Certified registered nurse anesthetist burnout related to moral distress: a replication study

Southern California CSU DNP Consortium California State University, Fullerton California State University, Long Beach California State University, Los Angeles POST BURN PRURITUS RELIEF PROTOCOL A DOCTORAL PROJECT Submitted in Partial Fulfillment of the Requirements For the degree of DOCTOR OF NURSING PRACTICE Doctoral Project Committee Approval: Gail Washington, DNS, RN, PHN, Project Chair Ayman Khalil Tailakh, PhD, RN, Committee Member Copyright Yeon Sook Kim 2015 Post burn pruritus is pervasive, occurring in over 90% of burn patients. Moreover, post burn pruritus continues in greater than 40% of patients for years even after burn wounds are healed. Post burn pruritus is a syndrome of stressful symptoms experienced by burn survivors that requires medical management with effective interventions. Unfortunately, many burn patients suffer from pruritus-related post burn injury regardless of current standard therapies. Therefore, in this Doctor of Nursing Practice project, published evidence including studies/reviews of post burn pruritus relief served as a basis for development of an advanced practice nurse (APN)-driven post burn pruritus relief protocol. A systematic review was conducted and relevant empiric articles from September 1, 2013 to November 17, 2014 were critically appraised. Initially, 79 articles were found; 38 articles were selected using pre-established inclusion criteria. Two frameworks were used to guide this project. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model was applied for the literature review and the Rosswurm and Larrabee's model for evidence-based practice change was used for clinical application. The newly developed APN driven post burn pruritus protocol is driven by burn healing phase (pre-healing, healing, post-healing), and emphasizes non-pharmacological interventions; it includes both non-pharmacological and pharmacological methods specifically intended for reducing burn associated pruritus.

In 1992, a Burn Nursing Delphi study classified pruritus as one of the highest priority areas in nursing research. However, there has been a lack of research examining the etiology and treatment of this highly distressing symptom (Goutos, 2010). Multiple studies (Carrougher et al., 2013; Goutos, Clarke, Upson, Richardson, & Ghosh, 2010; Goutos, Dziewulski, & Richardson, 2009) have examined post burn pruritus or itching and have varying findings. Each study, however, has consistently demonstrated a considerable level of pruritus in post burn populations. Casaer, Kums, Wouters, Van den Kerckhove and Van den Berghe (2008) reported that 49% of patients, even with small burn injury, experienced pruritus. Post burn pruritus can be defined as a severe itching sensation as a result of burn injury. Pruritus has been identified as one of the most general debilitating and stressful symptoms that post burn survivors experience (Bell & Gabriel, 2009; Goutos, 2010; Goutos, Dziewulski, & Richardson, 2009). The prevalence of post burn pruritus is seen in over 90% of burn patients and can persist in greater than 40% of those patients for 4 to 10 years after burn injury (Carrougher et al., 2013). According to Brooks et al. (2008), among patients with four years after burn injury, 79% reported intermittent problems with pruritus while 29% of patients reported persistent itching. However, twelve years after injury, these numbers decreased to 44% and 5%, respectively. According to Carrougher et al. (2013), itching prevalence is highly correlated with females, young age, large burn areas, more grafted areas, dry skin, and raised or thick scars. Casaer et al. (2008) more precisely reported that patients experienced more pruritus between the ages of 2 to 50 years old; if the burn area was large; and, the area of burn injury was on the trunk rather than the extremities. On the other hand, a study by Thompson et al. (2013) found no significant differences between age and gender regarding hypertrophic scars and pruritus. Thompson et al. (2013) reported burn size over 20% of total body surface area (TBSA) had increased risk of itching. Yang et al. (2014) found that patients with post burn pruritus had broader burned areas and more severe scars. According to Goutos et al. (2009), burn patients tend to have significant amount of itching within 1 month after burn injury with the highest at 6 months and a decline over the first year after the injury. They reported that the origin of a burn can affect associated pruritus. For example, scald injuries were most likely to provoke pruritus, followed by flame and contact injuries (Goutos et al., 2009). The reason for different findings from different studies was each study had different population characteristics regarding TBSA, ages, gender, and burn areas. However, larger size of burns are obviously more associated with post burn pruritus according to these studies (Carrougher et al., 2013; Casaer et al., 2008; Thompson et al., 2013). Post burn pruritus negatively impacts the quality of life in patients that included; sleep disturbances, decreased enjoyment with leisure activities, decreased ability to complete activities of daily living, and decreased school and work performance (Hettrick et al.,2004). In addition, about 60% of burn patients experienced difficulty falling asleep (Carrougher et al., 2013). According to Casaer et al. (2008), burn patients' daily life was impacted in 42% of those suffering from moderate pruritus and 92% of those suffering from severe pruritus. Parnell, Nedelec, Rachelska and LaSalle (2012) reported that pruritus was related to low concentration, agitation, anxiety, and flat mood. In general, researchers reported that pruritus triggered negative quality of life associated with dryness, heat, sweat, activity, stress, fatigue, physical effort, and special fabric. The problem of pruritus in post burn patients is well recognized. There are many potential treatments available for itching (Bell & Gabriel, 2009). However, none of the current standard therapies have been very effective (Otene & Onumaegbu, 2013). In addition, there is currently no accord on standardized treatment of post burn pruritus (Otene & Onumaegbu, 2013; Richardson, Upton & Rippon, 2014). Most often, therapies include pharmacological interventions that include a selective histamine receptor antagonist, but it is effective in only about 20% of patients (Brooks, Malic, & Judkins, 2008). This is because histamine is not the only element involved in the mechanism of itching, but also there are non-histamine dependent pathways involved in the pruritus mechanism according to the study by Schmelz (as cited in Brooks et al., 2008). Another treatment is emollients which also have limited usage. For example, a eutectic mixture of local anesthetic (EMLA) cream can be applied only to healed skin and the maximum zone treated is 600 cm2 for patients less than 19 kg and 2000 cm2 for patients greater than 20 kg (Brooks et al., 2008). This lack of effective care is further compounded by the absence of a standardized protocol. The Burn Nursing Delphi study (1992) identified the need for high impact potential antipruritic strategies to improve patient care (Goutos et Problem Statement
Post burn pruritus has been identified as one of the most general and stressful symptoms that burn survivors experience and should be aggressively managed (Bell & Gabriel, 2009; Goutos, 2010; Goutos, Dziewulski, & Richardson, 2009). Pruritus from post burn injury begins in the early stages of wound healing. Pruritus is usually prominent in patients who have second degree burns, but patients who experience third degree burns may also have partly second degree burns. Pruritus comes along with wound healing in the first two weeks after burn injury (Bell & Gabriel, 2009). Consistently research findings have strongly proposed that post burn pruritus management should be one of the top priorities for burn research (Bell & Gabriel, 2009; Brooks, Malic, & Judkins, 2008). Itching from associated burn injury that persists over a period of time leads to disabling symptoms such as sleep disturbance, anxiety, and interruption of daily activities (Goutos et al., 2009). Purpose Statement
The purpose of this project was to develop an advanced practice nurse (APN) driven post burn pruritus relief protocol that include pharmacological and non- pharmacological interventions in outpatient settings. This protocol would be used for patients experiencing post burn associated pruritus. Expected outcome of the protocol would be a reduction in post burn pruritus as determined by the 5 D Itch Scale and Visual Analogue Scale (VAS). This project has three objectives: 1) to conduct a systematic literature review; 2) identify non pharmacological and pharmacological relief interventions; and 3) identify an implementation change model for clinical practice. The target population for this project was all patients experiencing pruritus from second and third degree burns in various stages of wound healing. This project included post burn patients. The desired outcomes and benefits of this post burn pruritus protocol will improve the quality of life in patients with burn injuries (Casaer et al., 2008). Supporting Framework
This project used two supporting frameworks: the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model and the Rosswurm and Larrabee's model for evidence-based practice change. Further discussion of these models will be discussed in this paper. The purpose of this project was to construct a post burn pruritus relief protocol through a systemic literature review to develop a protocol in order to improve the quality of life in burn patients. The PRISMA model used to improve the reporting of systematic reviews and meta-analyses was used as the standard guideline for this systematic review (Liberati et al., 2009). The Rosswurm and Larrabee's model of evidence-based practice change was also used as an appropriate conceptual framework for evidence based practice in this project. The model incorporates principles of quality improvement, use of team work tools, and evidence-based translation strategies to support implementation of a new practice (Melnyk & Fineout-Overholt, 2011). In this project, developing a post burn pruritus protocol will promote quality care and improve patient outcomes. These frameworks were explained in the methods section of this project and is also integrated in reporting REVIEW OF LITERATURE
Overview
Bell and Gabriel (2009) reported the treatment of pruritus after burn injury by reviewing ten research articles that were clinical trials that included nine class II and one class III studies. Class II studies are reliable data that includes observational studies, cohort studies, prevalence studies, and case control studies. Class III studies, on the other hand, contain evidence provided by clinical series, comparative studies, case reviews, case reports, and expert opinion. According to their review, both pharmacologic and non-pharmacological methods significantly decreased post burn pruritus. Effective pharmacologic methods are selective antihistamine antagonists (cetirizine/cimetidine) in adult & pediatric population, Atarax and colloidal oatmeal (topical agent) in adult population, Gabapentin and EMLA (topical agent) in pediatric population. Effective non-pharmacologic methods contain pulsed dye laser and silicone gel sheeting in adult and pediatric patients, and massage and transcutaneous electrical nerve stimulation (TENS) in adult population. Bell and Gabriel (2009) suggested using moisturizing cream for all patients with post burn pruritus with different treatment plans based on the size of TBSA. According to the review by Goutos, Clarke, Upson, Richardson, and Ghosh (2010), a multidisciplinary approach is necessary in successful assessment and treatment. They recommended early use of centrally acting agents and peripherally acting agents as well as non-pharmacological interventions for the treatment of post burn pruritus in adult and pediatric populations. Rowley-Conwy (2014) also reported emollient cream, cool baths, pressure garments, and oral and topical antihistamines and analgesics were effective in decreasing burn associated pruritus. Rowley-Conwy (2014) also supported multidisciplinary team to manage burn patients' recovery for the best outcomes of physical, emotional, and psychological aspects. Goutos, Dziewulski, and Richardson (2009) suggested therapeutic strategies should be classified by interventions on peripheral & central aspects of the pruritic pathway. Interventions that focus on the peripheral aspects of burns are: cooling of the wound; antihistamines; topical Doxepin; local anesthetics; colloidal oatmeal; Capsaicin; Laser therapy; Aloe Vera; topical Dapsone; Unna boot; Compression garments; and, Ondansteron. Centralized interventions are Gabapentin; TENS; massage therapy; and, psychological support (Goutos et al., 2009; Zachariah et al., 2011). Findings for treatments to relieve post burn pruritus have been developed from several research studies and included diverse methods. However, there was only one suggested protocol found in the literature. This protocol focused on pharmacological methods and required physician orders. Therefore, this project has conducted a systemic review to develop a nurse driven post burn pruritus relief protocol. Pharmacological Topical Interventions
Pharmacological interventions are often used to relieve pruritus in burn patients. The first drug of choice for pruritus is antihistaminic drugs, especially, H1 antihistamines; approximately 90.91% of burn patients have had antihistamines prescribed for post burn pruritus (Goutos, 2010). According to Casaer et al. (2008), 23.3% of 258 adult and pediatric burn patients in clinical settings received antihistamines during their research study; and, those treated with antihistamines recalled that they felt reduced pruritus after the treatment. However, because participants also had ointments applied for pruritus, it was unclear how effective antihistamines alone were in decreasing pruritus. Ratcliff et al. (2005) evaluated the effectiveness of a pharmaco-therapeutic protocol for pain, anxiety, and itching among 286 acute pediatric burn patients in the hospital setting. They reported that 39.2% of participants received medication to control itching at the beginning, but eventually all the children took some type of oral itch medication because their burn wound itching intensity increased as the wound progressed. Ratcliff et al. (2005) accordingly recommended based on their research findings (1) moisturizing body shampoo, lotions, and topical ointments (not hydrocortisone creams); (2) Diphenhydramine 1.25mg/kg/dose orally every six hours; (3) if itch remains poorly controlled, subsequently add Hydroxyzine 0.6mg/kg/dose every 6hours, then Cyproheptadine 0.1mg/g/dose orally every six hours so that one of the medications could be given every two hours. Goutos (2010) stated that combination of H1 antihistamines and H2 antihistamines significantly decreased pruritus compared to using only H1 antihistamines. Goutos (2010) mentioned a combination of moisturization and three first generation H1 antihistamines was effective in 84% of acute burn inpatients. Second generation antihistamines are not used for pruritus because first generation antihistamines are commonly used for sedative effect as well as for pruritus relief. The study by Goutos (2010) demonstrated that 10 out of 22 burn units used additional pharmacological agent. Of the 10 units, 6 units used a second antihistamine, 1 used Ondansetron (serotonin receptor antagonist), and 3 used gabapentin with alone or combining with an antihistamine. Gabapentin has been more effective relieving pruritus in acutely burn patients than first generation antihistamines; especially, Chlorpheniramine Ahuja and Gupta (2012) compared the use of Pregabalin to other medicine in managing post burn pruritus for 80 adult patients in outpatient setting. They reported that the group using both antihistamine and Pregabalin and the group using Pregabalin only showed higher rates of remission of itching in post burn population compared to the group of using antihistamine only. However, in the population of mild itching, using both antihistamine and Pregabalin had a much higher rate (77.5%) than using only Pregabalin (23.3%) regarding reducing itching. Akhtar & Brooks (2012) explored the effect of botulinum toxin (Botox®) as a new agent in managing post burn pruritus and found that Botox® successfully decreased pruritus in 8 outpatient adult burn population who were resistant to conventional therapies. All eight post burn patients described itching as "0" out of 10 at 2weeks after Botox® injection. The average duration of no pruritus after the treatment was 9 months. The study of Baker et al. (2001) demonstrated the combination of histamine 1 (H1) receptor blocker and histamine 2 (H2) receptor blockers significantly reduced post burn pruritus than using H1 receptor blocker only during the first 4 days of treatment in 17 adult and pediatric patients. After 4days of treatment, there were no differences between two cases. Baker et al. (2001) also reported that programmed (scheduled) medication rather than medication on demand (PRN) contributed to the reduction of pruritus. The review by Goutos (2013) also reported that aggressive antihistamine was effective in the early phase, but in the later stages wounds appeared to be less effective to antihistamine therapy. Mendham's (2004) study was done to test the action of gabapentin on itching in healing wounds among 35 children admitted to the inpatient burn unit. The research sample was the population who had been treated with Chlorpheniramine and Trimeprazine, but still remained irritable and constantly itching wounds at the beginning of the research. Gabapentin was given starting as 5mg/kg three times a day and maximum dose increased up to 5mg/kg twice a day and 10mg/kg at night. Within 24 hours of gabapentin use, parents and nursing staff assessed the effects of the treatment and they stated that there was a remarkable reduction in itching and they had decreased or unused antihistamine intake. Ahuja, Gupta, Gupta, and Shrivastava (2010), studied the effectiveness of gabapentin in decreasing post burn pruritus comparing to using cetirizine alone and combination of gabapentin and cetirizine for 28days in 20 burn patients with ages of 12 to 70 years. The study showed that using gabapentin alone reduced itching in 95% of people in the group while cetirizine alone used group and combination of gabapentin and cetirizine used group reduced itching to 52% and 94%, respectively. In addition, the study demonstrated that the onset of action with gabapentin was significantly faster than the cetirizine. According to Ahuja et al. (2010), 74% in gabapentin group stated the relief of pruritus whereas 32% in the group with cetirizine alone stated pruritus relief on the third day after the treatment. Ahuja et al. (2010) suggested the need for pruritus relief protocol as well as the need for appropriate dosage of gabapentin treatment was needed to reduce post burn pruritus. Goutos, Eldardiri, Khan, Dziewulski, and Ricahrdson (2010) compared gabapentin treatment with antihistamine treatment in relieving acute post burn pruritus among 91 adult and pediatric burn population of inpatient setting. Gabapentin monotherapy was four times more effective than Chlorpheniramine monotherapy in acute burn pruritus (41.46% vs 10%). As an antipruritic polytherapy in acute burns, combination of gabapentin, cetirizine and Cyproheptadine was more effective than the combination of three antihistamines (Chlorpheniramine, Hydroxyzine, and Cyproheptadine) in relief rate of pruritus in post burn population. The outcome was 95.12% and 84%, respectively. Goutos et al. (2010) also suggested polytherapy in younger population and larger TBSA because monotherapy had higher failure rate in younger populations. Anand (2012) showed the effectiveness of gabapentin for pruritus in palliative care, too. According to the literature review by Anand (2012), gabapentin is safe and effective in uremic pruritus, cancer and hematologic causes, opioid-induced itch, brachioradial pruritus, burns pruritus, and pruritus of unknown origin. In the study by Goutos (2013), gabapentin had persistent therapeutic effect because of the ability to prevent central nervous system sensitization; Ondansetron was more effective in reducing pruritus than antihistamine; serotonin had pruritus relief effect; and TENS was more effective in reducing post burn pruritus during the remodeling phase. Warner, Coffee, and Yowler (2014) supported efficient outpatient burn management by using H-1 receptor blocking agent (cetirizine) during the early stage of pruritus as scheduled basis not as needed basis combined with frequent massage of moisturizers. In addition, neuro- inflammatory transmitter blockers (Gabapentin and Pregabalin) are effective because they prevent neuron transmitters from stimulating itch-specific neurons (Warner et al., The study by Otene and Onumaegbu (2013) revealed that 88.6% of 35 plastic surgeons had no assessment tool or method to evaluate post burn pruritus while only 11.4% believed they had a method of assessing the severity of post-burn pruritus. Otene and Onumaegbu (2013) also stated that "57.1% would use oral medications as first-line treatment, 22.9% would use injectables, 8.6% would use topical agents, 5.7% would only reassure the patients and another 5.7% would use a combination of oral and topical agents together. 85.7% of these plastic surgeons and burn care specialists did not have any form of anti-pruritic regimen, as only 14.3% indicated having this". Otene and Onumaegbu (2013) recommended Itch Man Scale as an assessment tool for pruritus and suggested rough guidelines as a pruritus relief management according to the score measured by Itch Man Scale. According to the review by Brooks et al. (2008), topical agents such as capsaicin and nanocrystalline silver ointment can be used to reduce pruritus. These drugs can also be used as part of a combination therapy. Topical steroid, Doxepin or Dothiepin cream (a tricyclic antidepressant), and EMLA can be used as part of a combination therapy in pharmacological interventions. One topical agent, Provase®, is a nonprescription moisturizer with a blend of protease enzymes. Nedelec, Rachelska, Parnell and LaSalle (2012) performed a prospective, double-blind, randomized, controlled, and pilot study to evaluate the effect of Provase® in reducing post burn pruritus in 18 burn patients. According to Nedelec et al. (2012), the application of Provase® to post burn population significantly reduced the duration and the frequency of pruritus, area of itch, and the presence of affective itch characteristics. For instance, treatment group reported the area of itch was decreased to half after four weeks of Provase® application. La Salle, Rachelska, and Nedelec (2007) evaluated the effect of naltrexone in managing post burn pruritus among 13 adult population in inpatient and outpatient settings. They reported research participants who had failed with H1 or H2 receptor antagonist and hydrating lotion demonstrated some satisfaction of naltrexone use in reducing post burn pruritus. Overall, 50% of research participants improved the frequency and duration of itching, 72% were satisfied with the itch relief provided by naltrexone, and 62% stated that quality of life improved by using naltrexone. Jung et al. (2009) did a study to determine the effects of naltrexone as a potential antipruritic medication for 19 adult burn population in the inpatient setting experiencing chronic refractory itching. All of the research subjects were population who had failed in reducing post burn pruritus with antihistamine, gabapentin, or both antihistamine and gabapentin before. However, researchers found out that 44.5% (9 patients) of research subjects reported decreased scratching activity two weeks after using naltrexone. Mugwort lotion seems to be effective in treating the itch associated with post burn pruritus who had hypertrophic scars (Ogawa & Hyakusoku, 2008). Mugwort lotion significantly decreased pruritus, sleep disturbance and redness after 2 months of treatment in 14 adult post burn patients of inpatient setting suffering from hypertrophic scars in the study by Ogawa & Hyakusoku (2008). Lewis et al. (2012) explored the efficacy of Medilixir (mixture of coconut, palm, castor, olive, hemp seed, wheat germ, and canola seed oil) compared to the standard treatment of aqueous cream (mixture of paraffin, heavy liquid, phenoxyethanol, and purified water) regarding relieving the post burn itch symptoms. Research findings indicate that Medilixir is more effective in minimizing post burn pruritus than aqueous cream in 52 adult burn population of inpatient setting. Campanati et al. (2013) evaluated the clinical effect of the topical application of Ozonated oil on second degree skin burns comparing to the treatment with hyaluronic acid gel. Thirty adult patients were applied Ozonated oil on half of the burn lesion and hyaluronic acid on the other half of the lesion once a day for 12weeks. Clinical features of each lesion (erythema, tension, height, itching, and burning sensation) were assessed at baseline, six, and twelve months after treatment. Ozonated oil had the same efficacy of hyaluronic acid in reducing symptoms related to burns (erythema, tension, height, itching, and burning sensation) after 12 weeks of topical application. Non-Pharmacological Interventions
Studies that have non-pharmacological interventions in relieving pruritus for burn population include: psychological interventions, massage therapy, silicone sheeting for burn wounds, hypnosis, TENS (transcutaneous electrical nerve stimulation), and Unna boot application (Brooks et al., 2008). Cold water, cold temperature, and rest also can relieve pruritus in some burn population (Parnell et al., 2012). The study by Goutos (2010) found that 2 out of 22 burn units utilized psychologists, 2 units used massage therapy, and 1 unit used silicone products for pruritic wounds and these methods were effective in reducing pruritus in burn patients. According to Upton, Penn, Richardson, and Rippon (2014), psychological approaches are effective in reducing wound itching. Upton et al. (2014) reviewed 12 published articles regarding psychological methods (habit reversal, suggestions, relaxation training, massage, and itch-coping programs) are used to treat wound associated pruritus. The study finding demonstrated psychological methods reduced itching but this approach was supported by only one article. Psychological interventions can be applied with consultation of a psychologist in conjunction with other therapies. Muscle relaxation methods decrease itching in burn populations. Farahanil, Hekmatpou, and Khani (2013) investigated the effect of muscle relaxation on pain, pruritus, and vital signs among 110 hospitalized adult and pediatric patients suffering from burns. They assessed pain, pruritus, and vital signs before and after the Benson relaxation method was applied. According to the study, muscle relaxation technique was effective in relieving the pain, pruritus, and vital signs of patients suffering from burns. Brooks, Phang, and Moazzam (2007) performed a case study with 5 cases including 7, 20, 40, 45, and 65% of TBSA having mixed-thickness burns from both inpatient and outpatient clinic and reported the effect of Acticoat® (Nanocrystalline silver) for itch relief in burn patients. Acticoat® was applied for 2 weeks and the intervals from original injury to application were 2, 3, 3, 6, and 8 months. Before and after 2 weeks of application, Visual Analog Scale (VAS) of itching was assessed and compared. VAS score was 7.4 before application and it decreased to 3.1 after application of Acticoat® (p = 0.002) which significantly reduced post burn pruritus. However, the study did not indicate the condition of wounds. For example, whether the burns were healed or unhealed was not stated. It is assumed they were unhealed or in the healing process because Acticoat® is used for unhealed wounds in current practice. Field et al. (2000) performed a randomized controlled trial (RCT) to evaluate the effect of massage therapy in reducing post burn itching, pain, and psychological symptoms of 20 adult burn patients in the outpatient setting suffering from pruritus. The research finding is massage therapy significantly decreases itching, pain, depression, and anxiety in post burn population with severe itching. According to Gurol, Polat, and Akcay (2010), massage therapy effectively alleviates pruritus in 63 burn adolescent inpatients even though this application is not commonly used. Pfab et al. (2013) reported in their review that 15 minute massage therapy twice a week over 5weeks reduced itching, pain, and anxiety levels in burn adolescents. The study by Cho et al. (2014) reported the effect of burn rehabilitation massage therapy on 146 adult inpatients with hypertrophic scars after acute burn care. Their findings indicated that burn massage therapy is effective in improving pain, pruritus, and scar characteristics in hypertrophic scars after burn (Cho et al, 2014). TENS is known as an ideal method of treating itching. The case study by Whitaker (2001) exhibited the effect of TENS in decreasing post burn pruritus. Whitaker (2001) applied TENS to a 19 year old patient at the inpatient setting who suffered from severe itching after being healed from 70% mixed thickness flame burns. After two weeks of using the TENS unit in the study, the patient did not need to continue the use of the TENS unit because post burn pruritus no longer existed. Hettrick (2004) evaluated the effect of TENS as the management of burn pruritus in a pilot study with RCT on 20 adult burn patients in the outpatient setting and reported TENS significantly reduced post burn pruritus in the population sampled. In the study, Hettrick applied one hours of TENS per day, 7 days a week for 3 weeks to the experimental group. It was suggested that TENS should be considered as a treatment option for burn survivors whose quality of life was negatively affected by itching (Hettrick, 2004). Silicone gel sheeting is considered effective in reducing scar pigmentation, pain, and itching as well as improving scar thickness and pliability (Li-Sang, Lau, Choi, Chan, & Jianan, 2006). The study by Li-Sang et al. (2006) demonstrated significant efficacy of silicone gel sheeting on severe post-traumatic hypertrophic scars among 45 Chinese adult outpatient burn population in their RCT. In a similar study, Li-Tsang, Zheng, and Lau (2010) investigated the effect of pressure therapy, silicone gel sheeting, and combined therapy on management of posttraumatic hypertrophic scar among 104 adult and pediatric burn population in the outpatient setting. All three methods significantly reduced itching but silicone gel sheeting had better results but was not statistically significant (Li-Sang et al., 2010). Laser therapy is one of ways to relieve pruritus. According to pretest and posttest designed study by Gaida et al. (2003), low level laser therapy (LLLT) was effectively decreased pain and pruritus in 19 adult post burn population of the outpatient setting. Likewise, Hultman, Edkins, Wu, Calvert, and Cairns (2013) reported that laser therapy on burn scars significantly improved pain, pruritus, pliability, and paresthesia among 147 outpatients (P < 0.0001). Waked, Nagib, and Ashm (2013) evaluated the effectiveness of triamcinolone acetonide phonophoresis (TAP) compared to TENS in the treatment of post burn pruritus for 40 adult inpatients. According to the researchers, there was a significant improvement in reducing pruritus in both group with TAP and the group with TENS (P<0.05). However, there was no significant difference between the two groups regarding the effect of pruritus reduction. Richardson, Upton and Rippon (2014) suggested an algorithm for the mechanism- based treatment of post burn pruritus based on the stages of healing. According to the algorithm by Richardson et al. (2014), there are four stages that include: inflammatory, inflammatory/proliferative, proliferative/remodeling, and remodeling. Each stage has different treatment methods. However, this algorithm is the only algorithm suggested and requires validation with further use in multiple studies. Summary of Literature Review
Summary of the literature review shows that Oral anti-pruritic medications are the first drug of choice and they can be given as a scheduled dose by combining with other anti-pruritic medications to be more effective in decreasing pruritus in post burn wounds regardless of wound healing stages. In addition, topical agents decrease post burn pruritus in healed wounds, especially, hypertrophic scars. These topical agents can be used with oral anti pruritic medications or after oral anti-pruritic medications have failed to relieve post burn pruritus. In addition, non-pharmacological interventions decreased post bun pruritus as effectively as pharmacological interventions. Effective non-pharmacological interventions were psychological intervention (habit reversal, suggestions, relaxation training, and itch-coping programs), pressure therapy, laser therapy, TAP, TENS, Massage, special dressing (silicone sheeting, Nanocrystallin [Acticoat®], and Unna boot), hypnosis, cold water, cold temperature, and rest. However, pharmacological interventions were suggested to augment non-pharmacological interventions to maximize This literature review analyzed 38 articles regarding post burn pruritus. 23 articles among them used VAS as a pruritus assessment tool, two articles used Itch man scale, two articles used both Itch man scale and VAS, and two articles used 5-D Itch scale. On the other hand, nine articles did not clearly state which pruritus assessment tool was used. Moreover, each treatment method was supported by less than five studies and most studies were relatively small sample size. Methods for this project included incorporating two models, the PRISMA model and the Rosswurm and Larrabee model of evidence-based practice change. Consistent with a systematic review, a table of evidence (TOE) was used for organization of the research studies (Appendix C). Methods contain: search strategy, eligibility criteria, study selection, data collection process, data extraction, quality assessment, and results. PRISMA Model
This project partly adopted the PRISMA flow diagram during the process of study selection and data collection. By using the PRISMA flow diagram, the selecting process of studies in this project was transparent. Steps for selecting research studies are identified in the PRISMA flow diagram (Figure 1), and includes: identification, screening, eligibility check, and inclusion of data. The PRISMA model for organizing and reporting systematic reviews includes an abstract, background, problem statement, purpose statement, methods, results, and discussion sections. These steps will be clearly delineated as headings throughout this paper. In the health sciences, 174 journals have used the PRISMA model for reporting systematic reviews and meta-analysis in their collections (Moher et al., 2009). The PRISMA model has also been considered as an assessment tool for research dissemination within the Enhancing the Quality and Transparency of Health Care Research (EQUATOR). The EQUATOR is an international initiative that seeks to improve reliability and value of health related research by promoting accurate and clear reporting of research studies (International Prospective Register of Systemic Reviews,


Figure 1. PRISMA 2009 flow diagram (Moher, Liberati, Tetzlaff, & Altman, 2009). The Model for Evidence-based Practice Change
Another framework for this project is the model for evidence-based practice change. This model, published by Rosswurm and Larrabee (1999), was a model used to change practice in an organization (Melnyk & Fineout-Overholt, 2011) and is closely related to the PRISMA model in that steps overlap. The Rosswurm and Larrabee model was based on theoretical and empirical literature related to evidence-based practice, research utilization, standardized language, and change theory. In this model, practitioners are guided through the entire process of developing and integrating an evidence-based practice change. The model supports evidence-based practice changes derived from a combination of quantitative and qualitative data, clinical expertise, and contextual evidence (Rosswurm & Larrabee, 1999). Because the purpose of this project was to develop a protocol to improve post burn pruritus and related symptoms, the model for evidence-based practice change was an appropriate framework for practice (Figure 2). In this model, step one included the background, problem statement, and literature review. In addition, step one assessed the need for change in practice by identifying the problem, inclusion of stakeholders, data collection of current practice, and development of a population-intervention-comparison-outcome- and time frame (PICOT). Step two was to locate the best evidence by identifying types and sources of evidence, reviewing research concepts, planning the search, and conducting the search (Table 1). Step three analyzed the evidence. This step included appraisal of the evidence, syntheses of the best evidence, and assessment of feasibility, benefits, and the risks of new practice. This project established incorporated step three under literature review and result. Step four was to design practice change and the development of a post burn pruritus relief protocol was the outcome of this step, and the protocol is contained in the results section. For the purposes of this time-limited DNP project steps five and six were not included and developing of a post burn pruritus relief protocol was sufficient, but this protocol will be tested in future research studies. Figure 2. A model of evidence-based practice change (Larrabee, 2009). Search Strategy
Four data bases: Cochrane Central Register of Controlled Trials, CINAHL the Cumulative Index of Nursing and Allied Health Literature, EBSCO, and PubMed were searched. In addition, The National Guideline Clearinghouse, and the following websites: Bandolier, The National Health Service (NHS) Center for Reviews and Dissemination, google scholar, and the American Burn Association (ABA) web site were used for searching data. Research articles were searched from September 1, 2013 to November 17, 2014. Key words linked with Boolean "AND" included burn(s), itch(ing), itch(es), pruritus, and pruritic. Data Extraction and Quality Assessment
In accordance with the PRISMA guidelines, articles were collected, studies reviewed for validity, potential bias, and threats. This review also included reviewing the articles for clarity of the clinical question, inclusion criteria, the relevance of the clinical question, study design, data collection, and analysis methods. Eligibility Criteria
According to the Iowa Model, systematic literature review was performed by formulating a focused clinical question about post burn pruritus (Holly, 2014). The question in the project is "In populations with burn injury, what measures are effective in minimizing post burn pruritus?" Initially, studies published within last five to seven years were inclusion criteria, but there were insufficient literature during the period. Therefore, the criteria for eligibility was expanded to all published studies written in English from 2000 to 2014 that performed on all second and third degree burn population suffering from burn related pruritus to collect sufficient data for the project. Study Selection and Data Collection Process
Purpose, design, sample, setting, findings of each study were recorded for the studies that were included in this review. Each paper was reviewed and analyzed descriptively. The systemic literature search of articles indicated that 38 studies met the inclusion criteria. A total of 79 articles were searched and 41 articles were excluded according to the flow diagram (Figure 3). First four articles were excluded; one was written in German, one was only response to the editor of the other article, and the other two articles were reviewed in other articles (duplication of research findings). Figure 3. Flow diagram for selection of studies. Next 22 studies were removed conforming to eligibility criteria: Seventeen articles were related only to scar, skin condition, and scar assessment; two studies were only regarding sleep quality in burn patients; and three articles stated general burns and their treatment only. Five articles were excluded because they were written about pruritus assessment tool development and evaluation only. Also, another study was not included because it stated general wound itching instead of writing specifically about post burn associated itching. Nine articles were excluded because they described only pruritus and did not write pruritus relief methods. Therefore, 38 articles were reviewed to develop a post burn pruritus relief protocol and significant findings of each study were shown in Table 1. Details of each publication was written in the Table of Evidence (TOE) under Appendix B. The TOE was constructed according to purpose, design, sample, setting, operational definition, findings, limitation of each study, and comments. A synthesis of each study was reported at the end of the review of literature.

PROJECT MANUSCRIPT
Thirty-eight articles were reviewed. Eighteen articles identified pharmacological effects on post burn pruritus that included single medicine use and two or three combined medicine. Effective pharmacological, both oral and topical, methods used in decreasing pruritus were antihistamines, Pregabalin, analgesics, corticosteroids, Gabapentin, Naltrexone, Botox, Provase, Capsaicin, colloidal oatmeal, Aloe Vera, topical Dapsone, Doxepin, Mugwort lotion, EMLA, Ozonated oil, and hyaluronic acid. Fifteen of the thirty eight articles stated positive non-pharmacological methods in relieving post burn pruritus. Examples of effective non-pharmacological methods included: cool bath, massage therapy, laser therapy, TENS, TAP, muscle relaxation, psychological approach, biofeedback therapy, silicone gel sheeting, Acticoat®, and pressure garment therapy. Of the studies, five supported combination of pharmacological and non-pharmacological methods to reduce post burn pruritus. The outcome of the systemic literature review regarding pruritus relief in post burn populations was synthesized and evaluated based on best outcomes which are pharmacological and non-pharmacological interventions. Accordingly, an advanced practice nurse (APN) driven post burn pruritus relief protocol was developed (Figure 4). This protocol was designed to apply to three different stages of wound healing such as: pre-healing (no granulation tissue); healing (partly granulated tissue); and healed stages (scar formation); and, recommended dosages per each intervention (Table2). Non- pharmacology interventions are recommended before pharmacological interventions based on established effectiveness. 1. Non-Pharmacological methods (Single or multiple options)

Non-pharmacological methods are less invasive interventions and are considered the primary intervention. On the other hand, Pharmacological methods are more invasive interventions and are most times used as a supplement to potentiate the effect of non-pharmacological interventions or to decrease possible adverse effects of combination medications. Non-pharmacological interventions are versatile and can be combined with any other non-pharmacological interventions as well as pharmacological interventions. Choice for non-pharmacological interventions will be considered by the facility's resources and patients' preferences. However, only one option from pharmacological interventions should be used with any non-pharmacological interventions only when non- pharmacological methods are not effective. Also, single medicine can be started when adding pharmacological methods. For example, in pre-healing stage, they can use all of non-pharmacological methods (both massage and Benson muscle relaxation therapy) and only one of pharmacological methods (either Pregabalin alone, Pregabalin & two antihistamines, Gabapentin alone, Gabapentin & H1 blocker, or Gabapentin & two H1 blockers, or Combination of H1 & H2 blockers). In this case, only Pregabalin needs to be initiated, but if Pregabalin alone does not effectively relieve pruritus two antihistamines can be added (Figure 4). Moreover, if pruritus persists regardless of interventions used, the following medications can be added to reduce symptoms: Zofran® (ondansetron), Serotonin, SSRI (selective serotonin reuptake inhibitor: Paroxetine), Doxepin® (tricyclic antidepressant), Gabapentin, Naltrexone, Topical Antihistamines, Topical Steroid, EMLA® Cream (lidocaine 2.5% & prilocaine 2.5%), Dothiepin (Tricyclic agent) cream, and Botox® (botulinum toxin). This post burn pruritus relief protocol was developed after a comprehensive systematic review of the literature with best practices identified. APNs can also use this evidence based protocol as standardized procedure for prescriptive authority. DISCUSSION
This protocol, the second of any post burn pruritus protocols is the first APN driven evidence based protocol that uses non-pharmacological interventions as a primary method of choice to reduce post burn pruritus. This protocol can be implemented in practice by APNs or RNs depending on the choice of interventions used. In addition, this protocol has recommended dosage and period for each intervention to clearly guide APNs and RNs. Using the Rosswurm and Larrabee model the nurse in clinical practice can assess the efficacy of this post burn pruritus protocol to ascertain if the protocol: 1) relieved discomfort from pruritus; 2) lessened disturbances on daily life that can include low concentration, agitation, anxiety, and a flat affect; 3) and increased quality of life. The 5-D Itch Scale (Appendix A) and/or the Visual Analogue Scale (Appendix B) are both valid and reliable and can be used before and then after the treatment method to quantify patient outcomes. The results from this systematic literature review and the model for implementing practice change, significantly contribute to the treatment of post burn pruritus. Non-pharmacological and Pharmacological interventions for post burn pruritus have been identified and presented in an easily identified protocol to improve patient outcomes and clinical practice. The findings of this systematic literature review and proposed protocol will help to advance the DNP role in research and translational inquiry. This protocol will be utilized in the future to develop interventional studies to enhance post burn pruritus management as well as to relieve patient suffering. REFERENCES
