Consumer focus group testing with stakeholders to generate an enteral resuscitation training flipbook for primary health center and first-level hospital providers in Nepal

INTRODUCTION

Enteral resuscitation (EResus) is operationally advantageous to intravenous resuscitation for burn-injured patients in some low-resource settings. However, there is minimal guidance and no training materials for EResus tailored to non-burn care providers. We aimed to develop and consumer-test a training flipbook with doctors and nurses in Nepal to aid broader dissemination of this life-saving technique.

MATERIALS AND METHODS

We used individual cognitive interviews with Nepali (n = 12) and international (n = 4) burn care experts to define key elements of EResus and specific concepts for its operationalization at primary health centers and first-level hospitals in Nepal. Content, prototype illustrations, and wireframe layouts were developed and revised with the burn care experts. Subsequently, eight consumer testing focus groups with Nepali stakeholders (5-10 people each) were facilitated. Prompts were generated using the Questionnaire Appraisal System (QAS) framework. The flipbook was iteratively revised and tested based on consumer feedback organized according to the domains of clarity, assumptions, knowledge/memory, and sensitivity/bias.

RESULTS AND DISCUSSION

The flipbook elements were iterated until consumers made no additional requests for changes. Examples of consumer inputs included: clarity-minimize medical jargon, add shrunken organs and wilted plants to represent burn shock; assumptions-use locally representative figures, depict oral rehydration salts sachet instead of a graduated bottle; knowledge/memory-clarify complex topics, use Rule-of-9 s and depict approximately 20% total body surface area to indicate the threshold for resuscitation; sensitivity/bias-reduce anatomic illustration details (e.g. urinary catheter placement, body contours).

CONCLUSION

Stakeholder engagement, consumer testing, and iterative revision can generate knowledge translation products that reflect contextually appropriate education materials for inexperienced burn providers. The EResus Training Flipbook can be used in Nepal and adapted to other contexts to facilitate the implementation of EResus globally.

Physical and psychosocial outcomes among burn-injured people with heterotopic ossification: A burn model system study

INTRODUCTION

Heterotopic ossification (HO), or ectopic bone formation in soft tissue, is a not so rare and poorly understood debilitating sequela of burn injury. Individuals developing HO following burn injuries to their hands often experience reductions in mobility, significant contractures, and joint pain. This study identifies demographic characteristics of individuals who develop HO and compares their physical and psychosocial outcomes to the general burn population.

METHODS

Participant demographics, injury characteristics, and PROMIS-29 scores across three time points (discharge, six- and 12- months after injury) were extracted from the Burn Model System National Longitudinal Database representing participants from 2015-2022. Mixed-effects linear regression models were used to compare PROMIS scores across all three longitudinal measurements. Models were adjusted for age, sex, race/ethnicity, HO status, and burn size.

RESULTS

Of the 861 participants with data concerning HO, 33 were diagnosed with HO (3.8% of participants). Most participants with HO were male (n = 24, 73%) and had an average age of 40 + /- 13 years. Participants with HO had significantly larger burn size (49 +/-23% Total Body Surface Area (TBSA)) than those without HO (16 +/-17%). Participants with HO reported significantly worse physical function, depression, pain interference and social integration scores than those without HO. After adjusting for covariables, participants with HO continued to report statistically significantly worse physical function than those without HO. Although physical functioning was consistently lower, the two populations did not differ significantly among psychosocial outcome measures.

CONCLUSIONS

While HO can result in physical limitations, the translation to psychosocial impairments was not evident. Targeted treatment of HO with the goal of maximizing physical function should be a focus of their rehabilitation.

Implementation of a geriatric care bundle for older adults with acute burns

BACKGROUND

Frailty and comorbidities are important outcome determinants in older patients (age ≥65) with burns. A Geriatric Burn Bundle (Geri-B) was implemented in 2019 at a regional burn center to standardize care for older adults. Components included frailty screening and protocolized geriatric co-management, malnutrition screening with nutritional support, and geriatric-centered pain regimens.

METHODS

This study aimed to qualitatively evaluate the implementation of Geri-B using the Proctor Framework. From June-August 2022, older burn-injured patients, burn nurses, and medical staff providers (attending physicians and advanced practice providers) were surveyed and interviewed. Transcribed interviews were coded and thematically analyzed. From May 2022 to August 2023, the number of inpatient visits aged 65 + with a documented frailty screening was monitored.

RESULTS

The study included 23 participants (10 providers, 13 patients). Participants highly rated Geri-B in all implementation domains. Most providers rated geriatric care effectiveness as 'good' or 'excellent' after Geri-B implementation. Providers viewed it as a reminder to tailor geriatric care and a safeguard against substandard geriatric care. Staffing shortages, insufficient protocol training, and learning resources were reported as implementation barriers. Many providers advocated for better bundle integration into the hospital electronic health record (EHR) (e.g., frailty screening tool, automatic admission order sets). Most patients felt comfortable being asked about their functional status with strong patient support for therapy services. The average frailty screening completion rate from May 2022 to August 2023 was 86%.

CONCLUSIONS

Geri-B was perceived as valuable for the care of older burn patients and may serve as a framework for other burn centers.

Implementation evaluation of tiered tele-triage pathways for burn center consultations and transfers

BACKGROUND

Early transfer to specialized centers improves trauma and burn outcomes; however, overtriage can result in unnecessary burdens to patients, providers, and health systems. Our institution developed novel burn triage pathways in 2016 to improve resource allocation. We evaluated the implementation of these pathways, analyzing trends in adoption, resource optimization, and pathway reliability after implementation.

METHODS

Triage pathways consist of transfer nurses (RNs) triaging calls based on review of burn images and clinical history: green pathway for direct outpatient referral, blue pathway for discussion with the on-call provider, red pathway for confirmation of transfer as requested by referring provider, and black pathway for the rapid transfer of severe burns. We used the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework to evaluate implementation. These pathways affected all acute burn referrals to our center from January 2017 to December 2019 (reach). Outcomes of interest were pathway assignment over time (adoption), changes to burn provider call volume (effectiveness), and the concordance of pathway assignment with final disposition (implementation reliability).

RESULTS

Transfer RNs triaged 5,272 burn referrals between 2017 and 2019. By January 2018, >98% of referrals were assigned a pathway. In 2018-2019, green pathway calls triaged by RNs reduced calls to burn providers by a mean of 40 (SD, 11) per month. Patients in green/blue pathways were less likely to be transferred, with >85% receiving only outpatient follow-up ( p < 0.001). Use of the lower acuity pathways increased over time, with a concordant decrease in use of the higher acuity pathways. Younger adults, patients referred from Level III to Level V trauma centers and nontrauma hospitals, and patients referred by APPs were less likely to be triaged to higher acuity pathways.

CONCLUSION

Implementation of highly adopted, reliable triage pathways can optimize existing clinical resources by task-shifting triage of lower acuity burns to nursing teams.

Examining the association between military service history and outcomes after burn injury

INTRODUCTION

The association between military service history and long-term outcomes after burn injury is unknown. This study uses data from the Burn Model System National Database to compare outcomes of individuals with and without self-reported military service history.

METHODS

Outcome measures were assessed at 12 months after injury including the Veterans Rand-12 Item Health Survey/Short Form-12, Satisfaction With Life Scale, Patient Reported Outcomes Measure Information System 29, 4-D Itch scale, Post Traumatic Stress Disorder Check List - Civilian Version, self-reported Post Traumatic Stress Disorder, and employment status. This study included 675 people with burns of whom 108 reported a history of military service.

RESULTS

The military service history group was more likely to be older, and male. Those with military service were most likely to be on Medicare insurance and those without military service history were most likely to be on Private Insurance/HMP/PPO. No significant differences were found between those with and without military service history in the outcome measures.

CONCLUSIONS

Further research should examine differences in outcomes between civilians and those with military service history, including elements of resilience and post traumatic growth.

Predictors at 6 and 12 Months for Social Participation Outcome at 24 Months in the Adult Burn Injury Population: A Burn Model System National Database Study

OBJECTIVE

To identify clinical factors (physical and psychological symptoms and post-traumatic growth) that predict social participation outcome at 24-month after burn injury.

DESIGN

A prospective cohort study based on Burn Model System National Database.

SETTING

Burn Model System centers.

PARTICIPANTS

181 adult participants less than 2 years after burn injury (N=181).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Demographic and injury variables were collected at discharge. Predictor variables were assessed at 6 and 12 months: Post-Traumatic Growth Inventory Short Form (PTGI-SF), Post-Traumatic Stress Disorder Checklist Civilian Version (PCL-C), Patient-Reported Outcomes Measurement Information System (PROMIS-29) Depression, Anxiety, Sleep Disturbance, Fatigue, and Pain Interference short forms, and self-reported Heat Intolerance. Social participation was measured at 24 months using the Life Impact Burn Recovery Evaluation (LIBRE) Social Interactions and Social Activities short forms.

RESULTS

Linear and multivariable regression models were used to examine predictor variables for social participation outcomes, controlling for demographic and injury variables. For LIBRE Social Interactions, significant predictors included the PCL-C total score at 6 months (β=-0.27, P<.001) and 12 months (β=-0.39, P<.001), and PROMIS-29 Pain Interference at 6 months (β=-0.20, P<.01). For LIBRE Social Activities, significant predictors consisted of the PROMIS-29 Depression at 6 months (β=-0.37, P<.001) and 12 months (β=-0.37, P<.001), PROMIS-29 Pain Interference at 6 months (β=-0.40, P<.001) and 12 months (β=-0.37, P<.001), and Heat Intolerance at 12 months (β=-4.55, P<.01).

CONCLUSIONS

Post-traumatic stress and pain predicted social interactions outcomes, while depression, pain and heat intolerance predicted social activities outcomes in people with burn injury.

Impact of Tele-Triage Pathways on Short-Stay Admission after Transfer to a Regional Burn Center for Acute Burn Injury

BACKGROUND

Regionalized care for burn-injured patients requires accurate triage. In 2016, we implemented a tele-triage system for acute burn consultations. We evaluated resource utilization following implementation, hypothesizing that this system would reduce short-stay admissions and prioritize inpatient care for those with higher burn severity.

STUDY DESIGN

We conducted a retrospective study of all transferred patients with acute burn injuries from January 1, 2010 to December 31, 2015, and January 1, 2017 to December 31, 2019. We evaluated the proportions of short-stay admissions (discharges less than 24 hours without operative intervention, ICU admission, or concern for nonaccidental trauma) among patients transferred before (2010 to 2015) and after (2017 to 2019) triage system implementation. Multivariable Poisson regression was used to evaluate factors associated with short-stay admissions. Interrupted time series analysis was used to evaluate the effect of the triage system.

RESULTS

There were 4,688 burn transfers (3,244 preimplementation and 1,444 postimplementation) in the study periods. Mean age was higher postimplementation (32 vs 29 years, p < 0.001). Median hospital length of stay (LOS) and ICU LOS were both 1 day higher, more patients underwent operative intervention (19% vs 16%), and median time to first operation was 1 day lower postimplementation. Short-stay admissions decreased from 50% (n = 1,624) to 39% (n = 561), and patients were 17% less likely to have a short-stay admission after implementation (adjusted relative risk [aRR], 0.83; 95% CI, 0.8 to 0.9). Pediatric patients younger than 15 years old composed 43% of all short-stay admissions and were much more likely than adult patients to have a short-stay admission independent of transfer timing (aRR, 2.36; 95% CI, 1.84 to 3.03).

CONCLUSIONS

Tele-triage burn transfer center protocols reduced short-stay admissions and prioritized inpatient care for patients with more severe injuries. Pediatric patients remain more likely to have short-stay admission after transfer.

Experiences of Alaska Native people living with burn injury and opportunities for health system strengthening

BACKGROUND

Injuries are a leading cause of death and disability for Alaska Native (AN) people. Alaska Native Tribal Health Consortium (ANTHC) is supporting the development of a burn care system that includes a partnership between Alaska Native Medical Center (ANMC) in Anchorage, AK and UW Medicine Regional Burn Center at Harborview Medical Center (HMC) in Seattle, WA. We aimed to better understand the experiences of AN people with burn injuries across the care continuum to aid development of culturally appropriate care regionalization.

METHODS

We performed focus groups with twelve AN people with burn injury and their caregivers. A multidisciplinary team of burn care providers, qualitative research experts, AN care coordinator, and AN cultural liaison led focus groups to elicit experiences across the burn care continuum. Transcripts were analyzed using a phenomenological approach and inductive coding to understand how AN people and families navigated the medical and community systems for burn care and areas for improvement.

RESULTS

Three themes were identified: 1-Challenges with local burn care in remote communities including limited first aid, triage, pain management, and wound care, as well as long-distance transport to definitive care; 2-Divergence between cultural values and medical practices that generated mistrust in the medical system, isolation from their support systems, and recovery goals that were not aligned with their needs; 3-Difficulty accessing emotional health support and a survivor community that could empower their resilience.

CONCLUSION

Participants reported modifiable barriers to culturally competent treatment for burn injuries among AN people. The findings can inform initiatives that leverage existing resources, including expansion of the Extension for Community Healthcare Outcomes (ECHO) telementoring program, promulgation of the Phoenix Society Survivors Offering Assistance in Recovery (SOAR) to AK, coordination of regionalized care to reduce time away from AK and provide more comfortable community reintegration, and define rehabilitation goals in terms that align with personal goals and subsistence lifestyle skills. Long-distance transport times are non-modifiable, but better pre-hospital care could be achieved by harnessing existing telehealth services and adapting principles of prolonged field care to allow for triage, initial care, and resuscitation in remote environments.

Higher Out-of-pocket Expenses are Associated with Worse Health-related Quality of Life in Burn Survivors: A Northwest Regional Burn Model System Investigation

The care required to recover serious burn injuries is costly. In the United States, these costs are often borne by patients. Examining the relationship between out-of-pocket (OOP) costs and health-related quality of life (HRQL) is important to support burn survivors. Financial data from a regional burn center were merged with data in the Burn Model System (BMS) National Database. HRQL outcomes included VA-Rand 12 (VR-12) physical component summary (PCS) and mental component summary (MCS) scores. Participant surveys were conducted at 6-, 12-, and 24-months post-injury. VR-12 scores were evaluated using generalized linear models and adjusted for potential confounders (age, sex, insurance/payer, self-identified race/ethnicity, measures of burn injury severity). 644 participants were included, of which 13% (84) had OOP costs. The percentage of participants with OOP costs was 34% for commercial/private, 22% for Medicare, 8% for other, 4% for self-pay, and 0% for workers' compensation and Medicaid. For participants with OOP expenses, median payments were $875 with an IQR of $368-1728. In addition to markers of burn injury severity, OOP costs were negatively associated with PCS scores at 6-months (coefficient -0.002, P < .001) and 12-months post-injury (coefficient -0.001, P = .004). There were no significant associations with PCS scores at 24 months post-injury or MCS scores at any interval. Participants with commercial/private or Medicare payer had higher financial liability than other payers. Higher OOP expenses were negatively associated with physical HRQL for at least 12 months after injury. Financial toxicity occurs after burn injury and providers should target resources accordingly.

Worse Itch and Fatigue in Racial and Ethnic Minorities: A Burn Model System Study

Racial and ethnic minority patients experience worse hypertrophic scars after burn injury than White patients. Subsequently, minority patients encounter differences in scar-related recovery domains such as itch and fatigue. This study examines disparities regarding postburn injury itch and fatigue in minority patients to better inform counseling and treatment considerations. From the multicenter National Institute of Disability, Independent Living and Rehabilitation Research Burn Model System Database (2015-2019), outcomes were analyzed at three time-points (discharge from index hospitalization, 6- and 12-months post-injury) using the 5D Itch and PROMIS-29 Fatigue measures. Multilevel linear mixed effects regression modeling analyzed associations between race/ethnicities and outcomes over time. Of 893 total patients, minority patients reported higher/worse itch scores at all time points compared to White patients. Itch scores were significantly higher for Black patients at 6 months (β = 1.42, P = .03) and 12 months (β = 3.36, P < .001) when compared to White patients. Black patients reported higher fatigue scores than White patients at all time points. Fatigue scores were significantly higher for Hispanic/Latino patients at discharge (β = 6.17, P < .001), 6 months (β = 4.49, P < .001), and 12 months (β = 6.27, P < .001) than White patients. This study supports investigation of potential factors leading to increased itch and fatigue such as sociocultural factors, disparities in healthcare access, and psychosocial impacts of these symptoms. In the short-term, minority patients may benefit from additional counseling and focused treatments addressing itch and fatigue after burn injury.

PROMIS-25 Reliability and Validity Among Children Living with Burn Injury: A Burn Model System National Database Study

This study examined the reliability and validity of the Patient Reported Outcomes Measurement System (PROMIS)-25, a profile instrument consisting of four-item fixed short forms for six health domains, in children living with burn injury. Data were provided by children participating in a multi-center longitudinal study of outcomes after burn injury. Floor and ceiling effects, unidimensionality, internal consistency, reliability, and differential item functioning (DIF) of the PROMIS-25 Profile v.2.0 were examined. Correlations with other established measures were calculated to assess concurrent validity. Children (n = 256) between the ages of 8-18 years with moderate to severe injury provided responses on PROMIS-25 domains. All PROMIS-25 domains showed high internal consistency. Substantial portions of the sample reported no symptoms (anxiety [58.2%], depressive symptoms [54.6%], fatigue [50.8%], pain [60.1%]). There was a large ceiling effect on peer relationships (46.8%) and physical function mobility (57.5%). One-factor confirmatory factor analyses supported unidimensionality for all domains. Reliability was sufficient for group mean comparisons (>0.8) across at least some trait levels for most domains except fatigue and anxiety. No DIF with respect to burn status was detected when comparing the burn sample to the PROMIS pediatric general U.S. population testing sample. These results provide evidence of reliability and validity of PROMIS-25 scores among children living with burn injury. Reliability of domains was low to moderate and would likely be improved, and ceiling effects reduced for some domains, by administering the PROMIS-37, which includes six items per domain.

Holistic Approach to Burn Reconstruction and Scar Rehabilitation

More than 11 million burn injuries occur each year across the world. Many people with burn injuries, regardless of injury size, develop hypertrophic scar, contracture, unstable scar, heterotopic ossification, and disability resulting from these sequelae. Advances in trauma systems, critical care, safe surgery, and multidisciplinary burn care have markedly improved the survival of people who have experienced extensive burn injuries. Burn scar reconstruction aims to improve or restore physical function, confidence, and body image. Like acute burn care, burn scar reconstruction requires thoughtful, coordinated approaches along the continuum of burn injury, recovery, and rehabilitation.

Preliminary Exploration of Long-Term Patient Outcomes After Tracheostomy in Burns: A Burn Model System Study

INTRODUCTION

Upper airway management is crucial to burn care. Endotracheal intubation is often performed in the setting of inhalation injury, burns of the face and neck, or large burns requiring significant resuscitation. Tracheostomy may be necessary in patients requiring prolonged ventilatory support. This study compares long-term, patient-reported outcomes in burn patients with and without tracheostomy.

MATERIALS AND METHODS

Data from the Burn Model System Database, collected from 2013 to 2020, were analyzed. Demographic and clinical data were compared between those with and without tracheostomy. The following patient-reported outcomes, collected at 6-, 12-, and 24-mo follow-up, were analyzed: Veterans RAND 12-Item Health Survey (VR-12), Satisfaction with Life, Community Integration Questionnaire, Patient-Reported Outcomes Measurement Information System 29-Item Profile Measure, employment status, and days to return to work. Regression models and propensity-matched analyses were used to assess the associations between tracheostomy and each outcome.

RESULTS

Of 714 patients included in this study, 5.5% received a tracheostomy. Mixed model regression analyses demonstrated that only VR-12 Physical Component Summary scores at 24-mo follow-up were significantly worse among those requiring tracheostomy. Tracheostomy was not associated with VR-12 Mental Component Summary, Satisfaction with Life, Community Integration Questionnaire, or Patient-Reported Outcomes Measurement Information System 29-Item Profile Measure scores. Likewise, tracheostomy was not found to be independently associated with employment status or days to return to work.

CONCLUSIONS

This preliminary exploration suggests that physical and psychosocial recovery, as well as the ability to regain employment, are no worse in burn patients requiring tracheostomy. Future investigations of larger scale are still needed to assess center- and provider-level influences, as well as the influences of various hallmarks of injury severity. Nonetheless, this work should better inform goals of care discussions with patients and families regarding the use of tracheostomy in burn injury.

Standardized trauma intake form with clinical decision support prompts improves care and reduces mortality for seriously injured patients in non-tertiary hospitals in Ghana: stepped-wedge cluster randomized trial

BACKGROUND

The WHO Trauma Care Checklist improved key performance indicators (KPIs) of trauma care at tertiary hospitals. A standardized trauma intake form (TIF) with real-time clinical decision support prompts was developed by adapting the WHO Trauma Care Checklist for use in smaller low- and middle-income country hospitals, where care is delivered by non-specialized providers and without trauma teams. This study aimed to determine the effectiveness of the TIF for improving KPIs in initial trauma care and reducing mortality at non-tertiary hospitals in Ghana.

METHODS

A stepped-wedge cluster randomized trial was conducted by stationing research assistants at emergency units of eight non-tertiary hospitals for 17.5 months to observe management of injured patients before and after introduction of the TIF. Differences in performance of KPIs in trauma care (primary outcomes) and mortality (secondary outcome) were estimated using generalized linear mixed regression models.

RESULTS

Management of 4077 injured patients was observed (2067 before TIF introduction, 2010 after). There was improvement in 14 of 16 primary survey and initial care KPIs after TIF introduction. Airway assessment increased from 72.9 to 98.4 per cent (adjusted OR 25.27, 95 per cent c.i. 2.47 to 258.94; P = 0.006) and breathing assessment from 62.1 to 96.8 per cent (adjusted OR 38.38, 4.84 to 304.69; P = 0.001). Documentation of important clinical data improved from 52.4 to 76.7 per cent (adjusted OR 2.14, 1.17 to 3.89; P = 0.013). The mortality rate decreased from 17.7 to 12.1 per cent among 302 patients (186 before, 116 after) with impaired physiology on arrival (hypotension or decreased level of consciousness) (adjusted OR 0.10, 0.02 to 0.56; P = 0.009).

CONCLUSION

The TIF improved overall initial trauma care and reduced mortality for more seriously injured patients.

Trajectories of physical health-related quality of life among adults living with burn injuries: A burn model system national database investigation to improve early intervention and rehabilitation service delivery

INTRODUCTION

Understanding trajectories of recovery in key domains can be used to guide patients, families, and caregivers. The purpose of this study was to describe common trajectories of physical health over time and to examine predictors of these trajectories.

METHOD

Adults with burn injuries completed self-reported assessments of their health-related quality of life (HRQOL) as measured by the SF-12® Physical Component Summary (PCS) score at distinct time points (preinjury via recall, index hospital discharge, and at 6-, 12-, and 24 months after injury). Growth mixture modeling (GMM) was used to model PCS scores over time. Covariables included burn size, participant characteristics, and scores from the Community Integration Questionnaire (CIQ)/Social Integration portion, Satisfaction With Life Scale (SWLS), and Satisfaction With Appearance Scale (SWAP).

RESULTS

Data from 939 participants were used for complete-case analysis. Participants were 72% male, 64% non-Hispanic White, with an average age of 44 years and an average burn size of 20% of total body surface area (TBSA). The best fitting model suggested three distinct trajectories (Class 1 through 3) for HRQOL. We titled each Class according to the characteristics of their trajectory. Class 1 (recovering; n = 632), Class 2 (static; n = 77), and Class 3 (weakened; n = 205) reported near average HRQOL preinjury, then reported lower scores at discharge, with Class 1 subsequently improving to preinjury levels and Class 3 improving but not reaching their preinjury quality of life. Class 3 experienced the largest decrease in HRQOL. Class 2 reported the lowest preinjury HRQOL and remained low for the next 2 years, showing minimal change in their HRQOL.

CONCLUSIONS

These findings emphasize the importance of early universal screening and sustained intervention for those most at risk for low HRQOL following injury. For Class 2 (static), lower than average HRQOL before their injury is a warning. For Class 3 (weakened), if the scores at 6 months show a large decline, then the person is at risk for not regaining their HRQOL by 24 months and thus needs all available interventions to optimize their outcomes. Results of this study provide guidance for how to identify people with burn injury who would benefit from more intensive rehabilitation to help them achieve or regain better HRQOL.

Systematic review of global hepatitis E outbreaks to inform response and coordination initiatives

INTRODUCTION

Hepatitis E virus (HEV) is the most common cause of acute hepatitis. While symptoms are generally mild and resolve within weeks, some populations (e.g., pregnant women, immunocompromised adults) are at high-risk of severe HEV-related morbidity and mortality. There has not been a recent comprehensive review of contemporary HEV outbreaks, which limits the validity of current disease burden estimates. Therefore, we aimed to characterize global HEV outbreaks and describe data gaps to inform HEV outbreak prevention and response initiatives.

METHODS

We performed a systematic review of peer-reviewed (PubMed, Embase) and gray literature (ProMED) to identify reports of outbreaks published between 2011 and 2022. We included (1) reports with ≥ 5 cases of HEV, and/or (2) reports with 1.5 times the baseline incidence of HEV in a specific population, and (3) all reports with suspected (e.g., clinical case definition) or confirmed (e.g., ELISA or PCR test) cases if they met criterium 1 and/or 2. We describe key outbreak epidemiological, prevention and response characteristics and major data gaps.

RESULTS

We identified 907 records from PubMed, 468 from Embase, and 247 from ProMED. We screened 1,362 potentially relevant records after deduplication. Seventy-one reports were synthesized, representing 44 HEV outbreaks in 19 countries. The populations at risk, case fatalities, and outbreak durations were not reported in 66% of outbreak reports. No reports described using HEV vaccines. Reported intervention efforts included improving sanitation and hygiene, contact tracing/case surveillance, chlorinating boreholes, and advising residents to boil water. Commonly missing data elements included specific case definitions used, testing strategy and methods, seroprevalence, impacts of interventions, and outbreak response costs. Approximately 20% of HEV outbreaks we found were not published in the peer-reviewed literature.

CONCLUSION

HEV represents a significant public health problem. Unfortunately, extensive data shortages and a lack of standardized reporting make it difficult to estimate the HEV disease burden accurately and to implement effective prevention and response activities. Our study has identified major gaps to guide future studies and outbreak reporting systems. Our results support the development of standardized reporting procedures/platforms for HEV outbreaks to ensure accurate and timely data distribution, including active and passive coordinated surveillance systems, particularly among high-risk populations.

Burn Care in Low-Resource and Austere Settings

More than 95% of the 11 million burns that occur annually happen in low-resource settings, and 70% of those occur among children. Although some low- and middle-income countries have well-organized emergency care systems, many have not prioritized care for the injured and experience unsatisfactory outcomes after burn injury. This chapter outlines key considerations for burn care in low-resource settings.

The Effect of Distance to Treatment Center on Long-Term Outcomes of Burn Patients

Geospatial proximity to American Burn Association (ABA)-verified burn centers or self-designated burn care facilities varies across the country. This study evaluates the effect of distance to treatment center on long-term, patient-reported outcomes. Data from the Burn Model System (BMS) National Longitudinal Database were analyzed. Demographic and clinical data were compared between three cohorts stratified by distance to BMS center (<20, 20-49.9, ≥50 miles). Distance to BMS center was calculated as driving distance between discharge and BMS center ZIP code centroids. The following patient-reported outcomes, collected at 12-months follow-up, were examined: Veterans RAND 12-Item Health Survey (VR-12), Satisfaction with Life (SWL) scale, employment status, and days to return to work. Mixed model regression analyses were used to examine the associations between distance to BMS center and each outcome, controlling for demographic and clinical variables. Of 726 patients included in this study, 26.3% and 28.1% were <20 and between 20 and 49.9 miles to a BMS center, respectively; 46.6% were ≥50 miles to a BMS center. Greater distance was associated with white/non-Hispanic race/ethnicity, preinjury employment, flame injury, and larger burn size (P < .001). Regression analyses did not identify significant associations between distance to BMS center and any patient-reported outcomes. This study suggests that patients treated at BMS centers have similar long-term, patient-reported outcomes of physical and psychosocial function, as well as employment, despite centralization of burn care and rehabilitation services. Given a steady decline in the incidence of burn injury, continued concentration of key resources is logical and safe.

Impacts of Financial Assistance on Quality of Life Among People Living With Burn Injury: Matched Cohort Analysis of the National Institute on Disability, Independent Living and Rehabilitation Research Burn Model System Database

Disparities in socioeconomic status and minority status affect the risk of burn injury and the severity of that injury, thus affecting the subsequent cost of care. We aimed to characterize the demographic details surrounding receipt of financial assistance due to burn injury and its relationship with health-related quality of life scores. Participants ≥18 from Burn Model System National Longitudinal Database (BMS) with complete demographic data were included (n = 4330). Nonresponders to financial assistance questions were analyzed separately. The remaining sample (n = 1255) was divided into participants who received financial assistance because of burn injury, those who received no financial assistance, and those who received financial assistance before injury and as a result of injury. A demographic and injury-characteristic comparison was conducted. Health-related quality of life metrics (Satisfaction with Life, Short Form-12/Veterans RAND 12-Item Health Survey, Community Integration Questionnaire Social Component, and the Post-Traumatic Growth Inventory) were analyzed preinjury, then 6-months, 1-year, and 2-years postinjury. A matched cohort analysis compared these scores. When compared to their no financial assistance counterparts, participants receiving financial assistance due to burns were more likely to be minorities (19% vs 14%), have more severe injuries (%TBSA burn 21% vs 10%), and receive workers' compensation (24% vs 9%). They also had lower health-related quality of life scores on all metrics except the post-traumatic growth inventory. Financial assistance may aid in combating disparities in posttraumatic growth scores for participants at the greatest risk of financial toxicity but does not improve other health-related quality of life metrics.

Veno-venous Extracorporeal Membrane Oxygenation for COVID-19: A Call For System-Wide Checks to Ensure Equitable Delivery For All

Extracorporeal membrane oxygenation (ECMO) has emerged in the COVID-19 pandemic as a potentially beneficial yet scare resource for treating critically ill patients, with variable allocation across the United States. The existing literature has not addressed barriers patients may face in access to ECMO as a result of healthcare inequity. We present a novel patient-centered framework of ECMO access, providing evidence for potential bias and opportunities to mitigate this bias at every stage between a marginalized patient's initial presentation to treatment with ECMO. While equitable access to ECMO support is a global challenge, this piece focuses primarily on patients in the United States with severe COVID-19-associated ARDS to draw from current literature on VV-ECMO for ARDS and does not address issues that affect ECMO access on a more international scale.

Defining numerical cut points for mild, moderate, and severe pain in adult burn survivors: A northwest regional burn model system investigation

INTRODUCTION

Pain is a common and often debilitating sequela of burn injury. Burn pain develops following damage to peripheral sensory nerves and the release of inflammatory mediators from injury. Burn pain is complex and can include background and procedural pain that result from the injury itself, wound care, stretching, and surgery. Clinicians and researchers need valid and reliable pain measures to guide screening, treatment, and research protocols. Unlike other conditions, visual analog, or numeric pain rating scale (VAS/NRS) scores that represent mild, moderate, and severe pain among people with burn injury have not been established. The aim of this study was to identify the most suitable average pain intensity rating scores for mild, moderate, and severe pain in adult burn survivors using a PROMIS Pain Interference (PROMIS-PI) short form.

METHODS

An average pain intensity VAS/NRS score (0-10) and customized PROMIS-PI short form were administered to adults with burn injury treated at a regional burn center at hospital discharge (baseline) and at 6, 12, and 24-months after injury. To identify pain intensity scores that represent mild, moderate, and severe pain, we computed F values and Bayesian Information Criterion (BIC) statistics associated with multiple ANOVA comparisons for mean pain interference scores by various pain intensity cut points. Six possible cut points (CP) were compared: CP 3,6; 3,7; 4,6; 4,7; 2,5; and 3,5. Optimal cut points were considered those with the highest ANOVA F statistics. Models with similar F statistics were also compared with BIC.

RESULTS

Data from a sample of 253 participants (83% white, 66% male, mean age 47 years) with VAS/NRS pain intensity and PROMIS-PI scores at one or more timepoints were analyzed. The optimal classification for mild, moderate, and severe pain was CP 2,5 at baseline and 12-months. Although CP 3,6 had the highest F value at 6-months, there was not strong evidence to support CP 3,6 over CP 2,5 (BIC difference: 2.9); similarly, CP 3,7 had the highest value at 24-months, but the BIC difference over CP 2,5 was only 2.2.

CONCLUSIONS

VAS/NRS scores for pain among adults with burn injury can be categorized as mild (0-2), moderate (3-5), and severe (6-10). These findings advance our understanding regarding the meaning of pain intensity ratings after burn injury, and provide an objective definition for clinical management, quality improvement, and pain research.

Perioperative Risk Assessment in Humanitarian Settings: A Scoping Review

BACKGROUND

No validated perioperative risk assessment models currently exist for use in humanitarian settings. To inform the development of a perioperative mortality risk assessment model applicable to humanitarian settings, we conducted a scoping review of the literature to identify reports that described perioperative risk assessment in surgical care in humanitarian settings and LMICs.

METHODS

We conducted a scoping review of the literature to identify records that described perioperative risk assessment in low-resource or humanitarian settings. Searches were conducted in databases including: PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature, Web of Science, World Health Organization Catalog, and Google Scholar.

RESULTS

Our search identified 1582 records. After title/abstract and full text screening, 50 reports remained eligible for analysis in quantitative and qualitative synthesis. These reports presented data from over 37 countries from public, NGO, and military facilities. Data reporting was highly inconsistent: fewer than half of reports presented the indication for surgery; less than 25% of reports presented data on injury severity or prehospital data. Most elements of perioperative risk models designed for high-resource settings (e.g., vital signs, laboratory data, and medical comorbidities) were unavailable.

CONCLUSION

At present, no perioperative mortality risk assessment model exists for use in humanitarian settings. Limitations in consistency and quality of data reporting are a primary barrier, however, can be addressed through data-driven identification of several key variables encompassed by a minimum dataset. The development of such a score is a critical step toward improving the quality of care provided to populations affected by conflict and protracted humanitarian crises.

Environmental impact of telehealth use for pediatric surgery

BACKGROUND

The healthcare sector is responsible for 10% of US greenhouse gas emissions. Telehealth use may decrease healthcare's carbon footprint. Our institution introduced telehealth to support SARS-CoV-2 social distancing. We aimed to evaluate the environmental impact of telehealth rollout.

METHODS

We conducted a retrospective cohort study of pediatric patients seen by a surgical or pre anesthesia provider between March 1, 2020 and March 1, 2021. We measured patient-miles saved and CO₂ emissions prevented to quantify the environmental impact of telehealth. Miles saved were calculated by geodesic distance between patient home address and our institution. Emissions prevented were calculated assuming 25 miles per gallon fuel efficiency and 19.4 pounds of CO₂ produced per gallon of gasoline consumed. Unadjusted Poisson regression was used to assess relationships between patient demographics, geography, and telehealth use.

RESULTS

60,773 in-person and 10,626 telehealth encounters were included. This represented an 8,755% increase in telehealth use compared to the year prior. Telehealth resulted in 887,006 patient-miles saved and 688,317 fewer pounds of CO₂ emitted. Demographics significantly associated with decreased telehealth use included Asian and Black/African American racial identity, Hispanic ethnic identity, and primary language other than English. Further distance from the hospital and higher area deprivation index were associated with increased telehealth use (IRR 1.0006 and 1.0077, respectively).

CONCLUSION

Incorporating telehealth into pediatric surgical and pre anesthesia clinics resulted in significant CO₂ emission reductions. Expanded telehealth use could mitigate surgical and anesthesia service contributions to climate change. Racial and linguistic minority status were associated with significantly lower rates of telehealth utilization, necessitating additional inquiry into equitable telemedicine use for minoritized populations.

Preferences for Oral Rehydration Drinks among Healthy Individuals in Ghana: A Single-Blind, Cross-Sectional Survey to Inform Implementation of an Enterally Based Resuscitation Protocol for Burn Injury

BACKGROUND

Enterally based resuscitation for major burn injuries has been suggested as a simple, operationally superior, and effective resuscitation strategy for use in austere contexts. However, key information to support its implementation is lacking, including palatability and acceptability of widely available rehydration drinks.

METHODS

We performed a single-blinded, cross-sectional survey of 60 healthy children (5-14 years), adults (15-54 years) and older adults (≥55 years) to determine palatability and overall acceptability of five oral rehydration solutions (ORS) and a positive control drink (Sprite Zero®) in Ghana. Quantitative data were described and differences between our control drink and the others across age groups were visually examined with Likert plots. Qualitative responses were analyzed using a content analysis framework.

RESULTS

Twenty participants in each age group completed the study. Participants were as young as 5 years and as old as 84 years. Nearly two thirds of the sample identified as male (n = 38, 63% of all participants). The positive control was reported to taste 'good or 'very good' by the majority of participants (89%) followed by lemon-flavored ORS (78%) and orange-flavored ORS (78%). Conversely, homemade and low-osmolarity ORS were reported to taste 'good' or 'very good' by only 20% and 15% of participants, respectively. There were no major taste differences across the age groups. However, children more frequently reported positively (i.e., tastes 'good' or 'very good') about flavored and sweet drinks than did adults and older adults. When faced with the hypothetical situation of being critically injured and needing resuscitation, participants tended to be more agreeable to consuming all the drinks, even low-osmolarity and homemade ORS.

CONCLUSIONS

These findings can be used to support the development of protocols that may be more acceptable among patients undergoing enterally based resuscitation, thus improving the effectiveness of the treatment. Specifically, enterally based resuscitation should likely include citrus-flavored ORS when available, given superior palatability and the fact that different flavor additives for patients of different ages do not seem necessary.

27 Pain Medication Use at Follow up Is Associated with Long-term Outcomes

Introduction

Use of prescription pain medication after burn injury is commonly required. However, little is known about long-term pain medication use and its association with outcomes. Therefore, the purpose of this study is to assess patterns of prescription pain medication use after discharge and the association between these medications and quality of life outcomes.

Methods

Data from the Burn Model System National Longitudinal Database (2015-2021) were analyzed. Pain medication use was assessed at pre-injury (recall at discharge), discharge (medical record) and follow-up (self-report at 6, 12, and 24 months after injury). Outcome measures included: VR-12 Physical and Mental Component Summary scores (PCS and MCS), Community Integration Questionnaire (CIQ), Posttraumatic Stress Disorder Checklist (PCL), Satisfaction with Life Scale (SWLS), and NeuroQOL Stigma. The population was divided into two groups, those taking and not taking prescription pain medications at one year. Regression analyses examined associations between prescription pain medication use and outcomes at 12 months, controlling for age, gender, race, ethnicity and burn size.

Results

Of the 645 participants, 15% reported prescription pain medication use prior to their burn. At discharge, 81% reported use of an opioid and 46% reported use of a neuropathic pain medication. At 12 months, 32% of individuals indicated prescription pain medication use. The pain medication group exhibited larger burn size (24.0% vs 15.2%) and longer hospital stays (40.4 vs 25.0 days) than the non-pain medication group (p< 0.0001 for all). Additionally, 25% of individuals who reported pre-injury pain medication use also reported use at 12 months. Regression analyses demonstrated that pain medication use was associated with worse physical health (PCS: coefficient 8.69, p< 0.0001) mental health (MCS: 6.31, p< 0.0001), stigma (NeuroQOL Stigma: 3.91, p< 0.0001), and satisfaction with life (SWLS: -3.66, p< 0.0001) at one year. Additionally, pain medication use was associated with 45% decreased odds of being employed (coefficient 0.55, p=0.029) and approximately 3 times greater odds of having post-traumatic stress disorder at 12 months (coefficient 3.25, p< 0.0001).

Conclusions

There are significant associations between prescription pain medication use and worse physical, mental and employment outcomes at twelve months. This information may be used to trigger screening and manage long-term recovery outcomes.

64 Community Level Disadvantage Negatively Impacts Return to Work After Burn Injury

Introduction

The loss of income from injury, additional health care expenses, and inability to return work can lead to unsatisfactory outcomes. Community level disadvantage (e.g., low high school completion, low home ownership, low income) are more common among minority groups. We hypothesized community level disadvantage would negatively impact the ability to return to work after burn injury. This could serve to identify patients who need focused social, vocational, and financial support during rehabilitation.

Methods

Data from adult participants in a large multicenter database from 1998-2021 were linked by zip-code to three multi-domain community level-indices: i) Distressed Communities Index, ii) Social Vulnerabilities Index (SVI), iii) Social Deprivation Index (SDI). Cohort characteristics, the distribution of each index within cohort, and days to return to work were described. Fit and strength of association between the indices and return to work was assessed with multi-level logistic regression models. A non-responder analysis examining demographic and clinical differences between was performed using Chi-square tests and Wilcoxon rank sum tests to understand potential bias in the findings.

Results

A total of 1960 participants provided both zip code and employment data 6 months after injury. 75% of participants were male. Mean age was 39. Race/Ethnicity Data: 81.4% identified as White, 11% Black, and 7% as “other” race; 84% of the participants as non-Hispanic or Latino. Median burn size was 20% TBSA (IQR 0.1-95.0), and length of hospitalization was 30 days (IQR 0-379). Of the community indices tested, both DCI and SVI were associated with return to work with DCI having the strongest association with return to work after injury, irrespective of indices. However, when DCI and SVI were included in the model to represent community disadvantage, the impact of race on return to work was less. Participants who did not provide employment information were younger, sustained larger burn sizes, and had longer LOS compared to those who did.

Conclusions

DCI and SVI are associated with return to work after burn injury and can be used to focus limited social, vocational, and financial services. Minoritized participants were less likely to return to work but they live in communities with greater disadvantage (e.g. fewer employment opportunities), which highlights the public health impacts of structural racism.

80 Validation of PROMIS-25 Among Children Living with Burn Injuries

Introduction

Patient-reported outcomes are important for burn injury research and clinical practice. The NIH-funded Patient Reported Outcomes Measurement System (PROMIS)-25 profile has been validated for use in diverse populations of children with many conditions, though not among children living with burn injuries. The purpose of this study was to examine the reliability and validity of PROMIS-25 scores in children living with burn injury.

Methods

Data were provided by children who were participating in a multi-center longitudinal study of outcomes after burn injury. The PROMIS-25 Profile, which includes 4 items for each domain of physical function mobility, anxiety, depression, fatigue, peer relationships, and pain interference, was evaluated for reliability and validity. Floor and ceiling effects, unidimensionality, internal consistency, and reliability were examined. Correlations with other measures (Post-Traumatic Growth Inventory-Child (PTGI-C), Child PTSD Symptom Scale (CPSS) and Burn Outcome Questionnaire Body Image Scale (BOQBI)) were calculated to assess concurrent validity.

Results

256 children living with burn injury who sustained a moderate to severe injury provided responses on PROMIS-25 domains 6 months-10 years post burn. Participants’ age ranged from 8-18 years at time of assessment; mean years since injury was 4.3 (SD 4.1). All PROMIS-25 domains showed high internal consistency (Cronbach’s α=0.90–0.95). Substantial portions of the sample reported no symptoms (anxiety [58.2%], depressive symptoms [54.6%], fatigue [50.8%], pain [60.1%]). There was a large ceiling effect on peer relationships (46.8%) and physical function mobility (57.5%). One-factor confirmatory factor analyses supported unidimensionality for all domains (all CFI >0.98). Reliability was credible for group mean comparisons ( >0.8) across at least some trait levels for all domains except fatigue and anxiety which had low reliability (< 0.8) across the entire trait range. The magnitude and direction of correlations were as anticipated (0.32 for peer relationships and body image; 0.51 for depressive symptoms and PTSD) with the exception of weak negative correlations between PTGI-C and the anxiety and depression domains.

Conclusions

The results provide some evidence of reliability and validity of PROMIS-25 scores among children living with burn injury. Reliability of all domains was low to moderate and would likely be improved, and ceiling effects reduced, by administering the PROMIS-37, which includes 6 items per domain.

122 PTSD Symptom Clusters as Predictors of Pain Interference in Burn Survivors

Introduction

Individuals who experience burns are at higher risk of developing post-traumatic stress disorder (PTSD) and chronic pain. There exists a synergistic relationship between PTSD and chronic pain in burn survivors. Theories exist about how aspects of each condition may perpetuate one another, or share underlying mechanisms. Both of these conditions are of relevance to pain-related disability. We sought to examine the role of individual PTSD symptom clusters as predictors of pain interference. We hypothesized that the hyperarousal and emotional numbing symptom clusters would be predictive of pain interference, even when accounting for the other two PTSD symptom clusters, pain intensity, and other covariates (burn size, hospital length of stay, age and gender).

Methods

Data were analyzed from the Burn Model System National Database. Inclusion criteria required participants to have a moderate to severe burn injury that required surgery for wound closure. Patient-reported outcome data: PTSD Checklist - Civilian, PROMIS-Pain Interference Short Form 4a, and a 0-10 average Pain Intensity item were analyzed at 6-months after injury. Hierarchical linear regression models were fit to examine the impact of PTSD symptom clusters on pain interference over and above that of pain intensity, and standardized betas were calculated (B).

Results

A total of 439 adult participants had complete responses on the measures of interest (e.g. PTSD symptoms, PROMIS-Pain Interference, and Pain Intensity) and were included in the analysis. Mean age, percent total body surface area burned, and hospital length of stay were 47 years, 18%, and 27 days, respectively. 69% were male and 82% were Caucasian. Results of a linear regression found that hyperarousal (B = .10, p = .03) and emotional numbing (B = .13, p = .01) PTSD symptom clusters were each significant predictors of pain-related disability, even when accounting for pain intensity (B = .64, p < .001). The covariates age, gender, days until discharge, and TBSA were all nonsignificant. The model accounted for 61% of the variance associated with pain-related disability.

Conclusions

Results highlight the importance of the emotional numbing and hyperarousal PTSD symptom clusters in explaining pain interference. Future evaluations parsing out the longitudinal relationships (i.e., beyond 6-months postburn) between PTSD symptom clusters, pain intensity, and pain interference, as well as evaluating other underlying mechanisms, are warranted.

73 Associations Between Pre-burn Occupation Type and Employment Outcomes at One Year

Introduction

Reintegration into the workforce after burn injury is an important issue for survivors. In a 2012 systematic review, 28% of burn survivors never returned to any form of employment. Although pre-burn employment status is strongly associated with post-burn employment, there are little data on the role of pre-injury occupation type on workplace reintegration. The aim of this project was to assess the impact of occupation type on employment outcomes after burn injury.

Methods

Data from the National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System National Longitudinal Database from 2015 to 2021 were used to investigate the association between occupation type and employment outcomes. Occupation type was classified into two groups, Labor and Non-labor, using the U.S. Bureau of Labor Statistics Standard Occupational Classification System. Demographic and clinical data were compared between groups. Mixed regression analyses examined associations between pre-burn occupation type and post-burn employment outcomes (employment at 1 year, days to return to work), controlling for age, gender, race, ethnicity, pre-injury employment, and burn size.

Results

Of the 600 patients who were employed pre-injury, 247 (41%) identified with a non-labor occupation and 353 (59%) with labor occupations. The Labor group was more male (82% vs. 61%) and Hispanic (23% vs. 6%), younger (mean age 42.1 vs. 48.3 years), less educated (high school or less, 25% vs. 11%) and more likely to have been injured at work (28% vs. 14%) compared to the Non-labor group (p< 0.001 for all comparisons). Changes in occupation were seen from pre-injury to post-injury; 16% of working survivors changed from Non-labor to Labor and 13% from Labor to Non-labor occupation types. For those who did return to work after injury, the average time to return to work was greater for Labor compared to the Non-labor group (150 vs 100 days; p=0.003). Additionally, those in the pre-injury Labor group were less likely to be employed at 12 months compared to the Non-labor group (odds ratio = 0.41; p=0.009).

Conclusions

Pre-injury occupation type is associated with employment outcomes after injury. Therefore, occupation type can be used to inform vocational reintegration resources, such as vocational rehabilitation programs, to optimize survivor outcomes.

10 The Impact of Insurance Disparities on Long-term Burn Outcomes: A Burn Model System Investigation

Introduction

Access to healthcare and insurance coverage are associated with quality of life, morbidity, and mortality outcomes. However, most studies have only focused on same-admission and short-term outcomes due to the lack of national longitudinal data and there is limited data on this topic in the burn literature. Our aim was to determine the effect of insurance status on long-term outcomes in a national sample of burn patients.

Methods

This is a retrospective study using the longitudinal Burn Model System National Database from January 2015 to April 2021. The inclusion criteria were all adult patients admitted for burn injury from participating sites. Main outcomes were the physical (PCS) and mental (MCS) health component summary scores of the Veterans RAND 12 (VR-12) score at 6, 12, and 24 months after injury. Multivariable regression was used to examine the association between insurance status and the outcomes, adjusting for demographics (i.e., age, gender, race/ethnicity) and burn injury severity.

Results

A total of 3,698 burn patients were included. Mean age was 43.39 (SD 15.84) years, 72% were male and 76% were white. Most patients had private/commercial insurance (56.37%), followed by Medicare (14.42%) and Medicaid (13.18%). The remaining 16% were uninsured patients (self-pay or philanthropy). Mean PCS scores were 43.64 (SD 10.87), 45.31 (SD 11.04) and 46.45 (SD 10.65) and Mean MCS scores were 47.80 (SD 12.35), 48.18 (SD 12.30) and 48.44 (SD 12.18) at 6, 12 and 24 months, respectively. In adjusted analyses, Medicaid insurance was associated with worse MCS at 6 months (Coefficient -3.90, p=0.001), and worse PCS at 12 and 24 months (Coefficient -3.09, p=0.004 and Coefficient -4.18, p< 0.001, respectively), compared to uninsured status. Medicare insurance was associated with worse PCS scores at 24 months (Coefficient -3.07, p=0.013).

Conclusions

Having Medicaid and Medicare insurance was significantly associated with a lower health-related quality of life at long-term follow up, even after adjusting for demographics and burn injury severity. Further studies need to focus on analyzing the reasons for these disparities and developing strategies to improve the quality of life of this subpopulation.

109 The Impact of Distance to Treatment Center on Long-term Outcomes of Burn Patients

Introduction

Geospatial access to American Burn Association (ABA)-verified burn centers or self-designated burn care facilities varies across the country. It is often necessary to transport patients hundreds of miles to provide definitive burn care and rehabilitation services. This study evaluates the impact of distance to treatment center on long-term outcomes of burn patients.

Methods

Data from the National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System (BMS) National Database, collected from 2015 to 2019, were analyzed to investigate the impact of distance to BMS center on long-term, patient-reported outcomes. Distance was calculated as driving distance between home zip code centroid and BMS center. Demographic and clinical data were compared between groups by distance from BMS center (< 20, 20-49.9, >50 miles). The following patient-reported outcome measures, collected 12 months after injury, were examined: Veterans Rand 12 Physical Component Summary Score (VR-12 PCS), Veterans Rand 12 Mental Component Summary Score (VR-12 MCS), Satisfaction with Life (SWL), employment status, and days to return to work. Mixed regression model analyses were used to examine the associations between distance to BMS center and each outcome measure, controlling for demographic and clinical variables.

Results

Of the 726 participants included in this study, 191 (26.3%) and 204 (28.1%) were < 20 and between 20-49.9 miles from a BMS center, respectively; 331 (46.6%) were >50 miles from a BMS center. Greater distance to BMS center was associated with white race/ethnicity (p< 0.001) and employment at time of injury (p=0.001). Greater distance to BMS center was also associated with flame injury (p< 0.001) and larger burn size (p< 0.001). There were no significant differences in length of stay or number of operations between groups. Regression analyses did not identify significant associations between distance to BMS center and VR-12 PCS, VR-12 MCS, SWL, employment at 12 months, or days to return to work.

Conclusions

After burn injury, patient-reported outcome measures of physical and psychosocial function, as well as employment, do not differ based on distance to BMS center.

125 Community Socioeconomic Status Is Associated with Social Participation Outcomes

Introduction

Socioeconomic factors are recognized as important social determinants of health. Data however are sparse describing the relationship between socioeconomic status and long term burn outcomes. This study aims to examine associations between community-level socioeconomic status and social participation outcomes in burn survivors.

Methods

Data was obtained from the Life Impact Burn Recovery Evaluation (LIBRE) Journey study that assesses longitudinal social participation outcomes of community dwelling burn survivors. Subjects were linked to the Distressed Communities Index (DCI), which combines seven indicators into a metric that depicts community economic well-being. Participants were categorized by time since burn (< 5, 5-15, ≥15 years). Linear regression models examined associations between DCI (zip code and county levels) and LIBRE domain scores (Family & Friends, Social Interactions, Social Activities, Work & Employment).

Results

The study included 314 burn survivors, (mean age 44.1 years; 61.0% female; 48.6% married; 82.8% white). The population was distributed among the time since injury categories (< 5: 35.8%, 5-15: 27.5%, ≥15: 36.7%). Approximately 18% of subjects were categorized in the “at risk” or “distressed” DCI categories. For survivors less than five years from burn, a DCI score increase of 1 standard deviation (worse socioeconomic status) at the zip code level was associated with decreased Family & Friends and Social Activity scores of 2.6 (p=.01) and 2.0 points (p=0.04), respectively (small effect sizes). This relationship was even stronger when controlling for sociodemographic factors. In regression analysis, survivors within the first five years from injury living in “at risk” or “distressed” communities showed worse Family & Friend scores by 6.5 points compared to those living in “prosperous” communities, even after adjusting for age, gender, race, ethnicity, education, and marital status (p=0.04; moderate effect size). There were no significant associations between DCI and LIBRE domain scores for survivors assessed beyond 5 years from injury.

Conclusions

Social participation outcomes were worse in burn survivors who lived in socioeconomically disadvantaged neighborhoods. Burn survivors who face socioeconomic challenges may need additional support to address social disparities to improve outcomes.

114 Long Term Impact of Hospital Acquired Multi-drug Resistant Organisms on Health-related Quality of Life

Introduction

MDROs colonize wounds and cause infections for hospitalized burn patients, which may lead to increased infection risk, wound complications, longer (LOS) and more cost. Little is known about the long-term impacts of MDRO colonization and infection on burn survivors. We aimed to describe the impacts of colonization on long-term health-related quality of life (HRQoL), itch, and pain.

Methods

Data from adult participants in a multicenter longitudinal outcome study were used. Data was described and χ ² and Kruskal-Wallis testing was applied to determine differences between the two groups. Outcomes included Veterans RAND 12 (VR-12) physical component summary score (PCS), and PROMIS 29 domains for pain intensity, fatigue, pain interference, physical function, and sleep disturbance. Pruritus was assessed using the 4-D Itch scale for total itch. Multilevel, multiple linear regressions were used for outcome measures at 6 m post-injury. Random effects regression with robust standard errors (SE) were used to evaluate the impacts over time.

Results

The study included 704 individuals and 92 were MDRO colonized (13%). Colonized patients had larger burns (25% TBSA, IQR 9-45 vs. 8% TBSA, IQR 3–20; p < .001), more operations (4, IQR 2-7 vs. 1, IQR 1-3; p < .001), more grafting (17% TBSA, IQR 3-46 vs. 3% TBSA, IQR 1- 9; p < .001), more ventilator days (2, IQR 0–8 vs. 0 IQR 0-0; p < .001), and longer LOS (34 days, IQR 17 – 64 vs. 16, IQR 9 - 27; p < .001). Adjusting for confounding covariables, such as demographics, colonization was associated with a lower PCS score (OR -0.33, 95% CI -0.68, -0.06; p=.018); a higher fatigue score (OR 0.46, 95% CI 0.13, 0.79; p = .007) and worse itch (OR 0.4, 95% CI -0.01, 0.75; p = .036). There was no association with pain intensity, pain interference, or sleep disturbance. Random effects regression indicated that colonization was associated with lower PCS (OR -5.0, 95% CI -8.60, -1.39; p = .007).

Conclusions

Impact of colonization extends beyond the immediate hospitalization and likely has long-term effects on HRQoL. Given our observation of lower physical function after MDRO, more granular research on taxa-specific effects, timing of colonization, and interventions are indicated to elucidate the impact on HRQoL.

717 Critically injured patients receiving kefir may have lower rates of Clostridium difficile

Introduction

Kefir is an easy to administer per feeding tube probiotic yogurt that does not contain the risk of powdered probiotics, which may contaminate patient wounds or intravenous lines. Previous studies show patients taking probiotics may decrease hospital-acquired infections (HAI) although kefir has not been well studied. We hypothesized that kefir would be well tolerated and prevent infections among critically injured patients including patients with burn injury on enteral nutrition (EN).

Methods

We performed a retrospective review of adult critically injured patients at a level 1 trauma and burn center from January 2018 to March 2021 who received EN. Patients with a history of clostridium difficile (C. diff) were excluded. Patients who received kefir were given 120ml twice daily. The kefir protocol was improved with input from clinical stakeholders. The rate of C. diff, catheter-associated urinary tract infection (CAUTI), and central line-associated blood stream infection (CLABSI) were compared between patients who received kefir and those who did not. Incidence rate ratios (IRR) and corresponding 95% confidence intervals were calculated to assess differences in these rates.

Results

3,814 patients met criteria, 545 of whom received kefir (14%). Suggested improvements to the kefir protocol by stakeholders were changing flavored to plain kefir to decrease the amount of carbohydrate, change to lactose-free kefir to improve usage in lactose intolerant patients, and educate nurses on flushing feeding tubes to avoid clogs.

None of the incidence rates of HAI were significantly different between patients who received kefir and those who did not (Table 1). Crude IRRs suggest that C. diff infections may have occurred less frequently among patients who received kefir while the reverse occurred for CLABSI infections, though these results are not significant.

Conclusions

The kefir implementation was refined by stakeholder feedback. Although no clear benefit of kefir was observed with HAI reduction, future research should investigate the potential association between kefir use and C. diff.

68 The Association Between Body Mass Index and Physical Function in Adult Burn Survivors

Introduction

An area of rehabilitation research in burns is the impact of co-morbidities. Obesity is one of these, is an increasing public health concern, and its role remains controversial regarding burn injury and physical recovery. Our aim was to evaluate associations between body mass index (BMI) as a measure of obesity, at discharge and self-reported physical function (PF) during recovery of adult burn survivors.

Methods

This study included data that was collected by four American Burn Association-verified burn centers, which contribute to the Burn Model System National Database project. The data included BMI obtained at hospital discharge and self-reported Patient-Reported Outcomes Measurement Information System (PROMIS)-29 PF-mobility and upper extremity scores assessed at 6-, 12-, and 24-months after burn. Mixed linear models for repeated measures and regression models were used to assess associations between BMI and PROMIS-29 PF scores over time. Values are expressed as means ± SD. Significance was set at p&lt; 0.05.

Results

A total of 502 adult patients aged 47 ± 16 years were included, with mean total body surface area burned (TBSA) of 17 ± 18 % (range; 1.0-88%) and mean BMI of 23.1 ± 5.4 kg*m-2 (range; 14.0-64.7 kg*m-2). We found no significant effect at 6 months (beta=-0.045, p= 0.54) nor at 12 months after injury (beta=-0.063, p= 0.44) when adjusted for age, burn size, and sex, however, BMI at discharge had a significant negative effect on self-reported mobility scores 24 months after injury (beta=0.218, p=&lt; 0.05).

Conclusions

Increased weight (i.e. BMI) at discharge was negatively associated with PF during recovery. Benefiting from a large sample size, our analysis suggests that long term recovery and restoration of PF in adult burn survivors is compromized by excess body weight.

38 Utilizing an Implementation Science Framework to Design a Burn Resuscitation Bundle in a Resource-limited Setting

Introduction

Protocolized burn resuscitation algorithms with hourly, closed loop feedback, have reduced instances of over- and under-resuscitation and improved outcomes in high income countries. However, a “know-do” gap exists as this practice has yet to be adopted in many low- and middle-income countries (LMIC). We aimed to describe the change management process of the development and implementation of a contextually driven protocolized burn resuscitation bundle at a tertiary burn center in an LMIC using an implementation science framework.

Methods

We applied strategies from the Expert Recommendations for Implementing Change (ERIC) for the design and implementation of a burn resuscitation bundle at a major burn center in an LMIC, over a 9-month period. Semi-structured focus group discussions (FGD) were conducted with stakeholders to understand facilitators and barriers to developing and using the protocol, with iterative feedback used to inform and adjust the protocol and documentation tools. Responses were analyzed using content analysis and particularly unique and useful responses were highlighted.

Results

Stakeholders identified resource constraint-related concerns about the feasibility of an hourly IV resuscitation protocol and reached consensus on performing 2-hourly assessments and fluid adjustments. Corresponding documentation tools were developed and iteratively adjusted. Several initial barriers to adoption and institutionalization were encountered. ERIC strategies used to promote intervention uptake included simplification and visualization of the protocol, identification of a project champion, development of educational materials for multiple cadres (e.g., nurses, physicians, health assistants), use of chain of command to enable change and accountability, utilizing institutional branding and ultimately obtaining endorsement by the center’s leadership (Table 1). Post-implementation FGD with stakeholders revealed high levels of acceptance, utilization and adherence of the protocol bundle, with occasional opportunities for improvement identified in protocol completeness and accuracy.

Conclusions

Adoption of change in clinical resuscitation practice in a resource-constrained setting required a contextually driven, multi-faceted approach led by a team of change champions and leaders. The ERIC framework allowed for an iterative approach to prioritize stakeholder engagement and feedback, in order to implement a protocolized IV resuscitation bundle in a LMIC.

78 Classification and Regression Tree Model for Predicting Satisfaction with Life Scale Scores After Burn Injury

Introduction

Current early burn care prognostication models predict in-hospital mortality (e.g., revised Baux Score). However, patients, families and clinicians need more holistic tools in the hours and days after injury to identify specific factors that might affect their quality of life and indicate a need for more intensive services. This project aims to predict Satisfaction with Life (SWL) in survivors of burn injury using patient, injury, and care factors available within 24 hours of admission.

Methods

Two hundred and fourteen participants were identified from a multicenter national longitudinal database and merged with clinical data from a single institution's trauma registry. Patients were randomized into a training dataset (80%) and a testing dataset (20%). A CART algorithm was used to examine the relative contributions of individual predictor variables in classifying low SWL at six-month follow up (SWL ≤ 20). Seventeen covariables obtained within 24 hours of index hospital admission were analyzed from five domains: demographics, comorbidities, injury, care, and host response to injury. Lab values were those closest to but not greater than 24 hours after index hospital admission.

Results

Multiple covariables contributed to the SWL score. CART analysis selected a pre-injury SWL score < 31 as the first node and strongest indicator of low SWL. CART then selected the following subgroups at risk for SWL ≤ 20 at 6 months: (1) hematocrit >55%; (2) lactate >4 mmol/L, age > 59; (3) total body surface area (TBSA) burned >30%, presence of a hand, neck, and/or face burn. The cross-validated predictive accuracy of the CART model was 69.4% with a cross-validated relative error of 0.379. In the validation data set, sensitivity and specificity were 62.5% and 72.0%, respectively.

Conclusions

The findings demonstrate the potential feasibility of creating a model that can predict a clinically meaningful quality of life outcome using covariables gathered within hours of hospital admission after burn injury. Predictive measures suggest that while some of the included covariables may be associated with SWL, they are not consistently and reliably predictive of low SWL alone. With more data and additional refined inputs, a similar model could be used to identify those in need of more intensive services earlier on in the hospitalization.

83 The Impact of Tracheostomy on Long-term Patient Outcomes: A Burn Model System National Database Study

Introduction

Management of the upper airway is crucial to burn care, especially in the setting of inhalation injury or burns to the face or neck. Endotracheal intubation is often performed to secure the airway; however, tracheostomy may be necessary in patients requiring prolonged ventilatory support. This study compares long-term outcomes of burn patients with and without tracheostomy.

Methods

Data from the Burn Model System National Database, collected from 2013 to 2020, were analyzed. Demographic and clinical data were compared between those with and without tracheostomy. The following patient-reported outcome measures, collected at 6-, 12-, and 24-months, were analyzed: Veterans Rand 12 Physical Component Summary Score (VR-12 PCS), Veterans Rand 12 Mental Component Summary Score (VR-12 MCS), Satisfaction with Life (SWL), Community Integration Questionnaire (CIQ), Patient-Reported Outcomes Measurement Information System (PROMIS-29), employment status, and number of days to return to work. Regression models were used to assess the impact of tracheostomy status on long-term outcome measures, controlling for demographic and clinical variables.

Results

Of the 714 patients included in this study, 39 (5.46%) received a tracheostomy and 675 (94.54%) did not. The two groups were similar across all demographic data collected. Tracheostomy patients were more likely to have flame injury, inhalation injury, larger burn size, more trips to the operating room, longer hospital stay, and greater number of days on a ventilator (p< 0.001). Regression model analyses demonstrated that tracheostomy was associated with worse VR-12 PCS scores at 6-, 12-, and 24-months (6.6 [95% CI 1.5, 11.8], p=0.012; 11.5 [6.2, 16.8], p< 0.001; 10.8 [4.2, 17.5], p=0.001). Tracheostomy was also associated with worse scores in two PROMIS-29 domains, physical function and pain interference. For physical function, the association was seen at 6-, 12-, and 24-months (7.4 [3.0, 11.8], p=0.001; 9.6 [5.2, 14.0], p< 0.001; 11.3 [5.8, 16.9], p< 0.001). For pain interference, the association was only seen at 12-months (-5.3 [-10.0, -0.55], p=0.029).

Conclusions

After burn injury, patient-reported outcome measures of physical function and pain interference were significantly worse with tracheostomy.

The Impact of Burn Survivor Preinjury Income and Payer Status on Health-Related Quality of Life

The costs required to provide acute care for patients with serious burn injuries are significant. In the United States, these costs are often shared by patients. However, the impacts of preinjury finances on health-related quality of life (HRQL) have been poorly characterized. We hypothesized that lower income and public payers would be associated with poorer HRQL. Burn survivors with complete data for preinjury personal income and payer status were extracted from the longitudinal Burn Model System National Database. HRQL outcomes were measured with VR-12 scores at 6, 12, and 24 months postinjury. VR-12 scores were evaluated using generalized linear models, adjusting for potential confounders (eg, age, sex, self-identified race, burn injury severity). About 453 participants had complete data for income and payer status. More than one third of BMS participants earned less than $25,000/year (36%), 24% earned $25,000 to 49,000/year, 23% earned $50,000 to 99,000/year, 11% earned $100,000 to 149,000/year, 3% earned $150,000 to 199,000/year, and 4% earned more than $200,000/year. VR-12 mental component summary (MCS) and physical component summary (PCS) scores were highest for those who earned $150,000 to 199,000/year (55.8 and 55.8) and lowest for those who earned less than $25,000/year (49.0 and 46.4). After adjusting for demographics, payer, and burn severity, 12-month MCS and PCS and 24-month PCS scores were negatively associated with Medicare payer (P < .05). Low income was not significantly associated with lower VR-12 scores. There was a peaking relationship between HRQL and middle-class income, but this trend was not significant after adjusting for covariates. Public payers, particularly Medicare, were independently associated with poorer HRQL. The findings might be used to identify those at risk of financial toxicity for targeting assistance during rehabilitation.

77 Impacts of Financial Assistance on Quality of Life Among People Living with Burn Injury

Introduction

Financial toxicity negatively impacts recovery after injury. Financial assistance (FA; e.g., disability income, food stamps, low-income housing voucher) may mitigate the impacts of financial toxicity. We aimed to describe FA after burn injury and its association with health-related quality of life (HRQL) and return to work.

Methods

Data from adult participants participating in a multicenter longitudinal database from 2015 to 2021 were used for complete-case analysis. Participants were separated into two groups: those who received any form of financial assistance due to their burn injury, and those who did not. The cohort and FA were described. Multi-level, mixed-effects, linear regression was performed to assess the associations of FA with VR-12 Physical and Mental Health Component Summary scores (PCS, MCS) and return to work. Lastly, a propensity score analysis matched 3:1 on age, gender, pre-injury PCS and MCS, burn size, length of hospital stay, and the number of operations as a result of burn injury was used to maximally reduce potential confounding.

Results

The analysis included 1,237 participants [725 who received FA, 512 who did not receive FA (NFA)]. Participants who received FA due to their burn injury were more likely to be younger (median 42 FA vs 48 NFA, p-value < 0.001), racially minoritized (19.2% FA vs 14.3% NFA, p-value < 0.001), have larger injuries (21% FA vs. 10% TBSA NFA, p-value < 0.001), longer hospital stays (median 29.5 days FA vs. 17 days NFA, p-value < 0.001), more days before returning to work (median 220 days FA vs 79 days NFA, p-value < 0.001), and have a workers compensation insurance payer (23.6% FA vs. 9.38% NFA, p-value < 0.001) compared to peers who did not receive FA. The number of participants who received new FA decreased after the 6-month time point: 11% at discharge, 33% at 6 months, and 15% at 12 months. Propensity score analysis demonstrated that receiving FA was associated with lower PCS and MCS scores at all time points and longer time to return to work (Table 1).

Conclusions

Given that financial toxicity is associated with unsatisfactory recovery after injury, efforts to reduce financial stressors are needed. FA seems somewhat matched to patients with greater recovery challenges (e.g., larger injuries, more complex hospitalizations). Additionally, most patients do not receive FA for a prolonged period (e.g., >6 months). While FA is associated with lower HRQL and longer return to work, these data may represent improvement compared to what people living with burn injury might have experienced without FA and represent unmeasured confounding.

Burn Outcomes at Extremes of Body Mass Index- Underweight is as problematic as Morbid Obesity

Limited evidence suggests that obesity adversely affects burn outcomes. However, the impacts of body mass index (BMI) across the continuum has not been fully characterized. Therefore, we aimed to characterize outcomes after burn injury across the BMI continuum. We hypothesized that 'normal' BMI (18.5-24.9) would have the lowest mortality and complication rates. The US National Trauma Data Bank (NTDB) was queried for adult burn-injured patients from 2007-2015. Admission BMI was calculated and grouped according to World Health Organization (WHO) classification. The primary outcome was in-hospital mortality. Secondary outcomes of time to wound closure, length of stay (LOS), and inpatient complications were similarly assessed. Of the 116,008 burn patient encounters that were identified, 7,243 underwent at least one operation for wound closure. Mortality was lowest in the overweight (p=0.039) and obese I cohorts (BMI 25-29.9, 30.0-34.9) at 2.9% and increased in both directions of the BMI continuum to 4.1% in the underweight (p=0.032) and 5.1% in the morbidly obese (class III) group (p=0.042). Time to final wound closure was longest in the two BMI extremes. BMI >40 was associated with increased ICU days, ventilator days, renal and cardiac complications. BMI <18.5 had increased hospital days and rates of sepsis. Aberrations in metabolism associated with both increases and decreases of body weight may cause pathophysiologic changes that lead to worsened outcomes in burn-injured patients. In addition to morbidly obese patients, underweight patients also experience increased burn-related death and complications. In contrast, overweight BMI patients may have greater physiologic reserves without the burden of obesity or sarcopenia.

Global trends in pediatric burn injuries and care capacity from the World Health Organization Global Burn Registry

BACKGROUND

Burn injuries are a major cause of death and disability globally. The World Health Organization (WHO) launched the Global Burn Registry (GBR) to improve understanding of burn injuries worldwide, identify prevention targets, and benchmark acute care. We aimed to describe the epidemiology, risk factors, and outcomes of children with burns to demonstrate the GBR's utility and inform needs for pediatric burn prevention and treatment.

METHODS

We performed descriptive analyses of children age ≤ 18 years in the WHO GBR. We also described facility-level capacity. Data were extracted in September of 2021.

RESULTS

There were 8,640 pediatric and adult entries from 20 countries. Of these, 3,649 (42%) were children (0-18 years old) from predominantly middle-income countries. The mean age was 5.3 years and 60% were boys. Children aged 1-5 years comprised 62% (n = 2,279) of the cohort and mainly presented with scald burns (80%), followed by flame burns (14%). Children >5 years (n = 1,219) more frequently sustained flame burns (52%) followed by scald burns (29%). More than half of pediatric patients (52%) sustained a major burn (≥15% total body surface area) and 48% received surgery for wound closure during the index hospitalization. Older children had more severe injuries and required more surgery. Despite the frequency of severe injuries, critical care capacity was reported as "limited" for 23% of pediatric patients.

CONCLUSIONS

Children represent a large proportion of people with burn injuries globally and often sustain major injuries that require critical and surgical intervention. However, critical care capacity is limited at contributing centers and should be a priority for healthcare system development to avert preventable death and disability. This analysis demonstrates that the GBR has the potential to highlight key epidemiological characteristics and hospital capacity for pediatric burn patients. To improve global burn care, addressing barriers to GBR participation in low- and low-middle-income countries would allow for greater representation from a diversity of countries, regions, and burn care facilities.

Validation of PROMIS-29 domain scores among adult burn survivors: A National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System Study

BACKGROUND

Patient-reported outcomes are important for understanding recovery after burn injury, benchmarking service delivery and measuring the impact of interventions. Patient-Reported Outcomes Measurement Information System (PROMIS)-29 domains have been validated for use among diverse populations though not among burn survivors. The purpose of this study was to examine validity and reliability of PROMIS-29 scores in this population.

METHODS

The PROMIS-29 scores of physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social roles, and pain interference were evaluated for validity and reliability in adult burn survivors. Unidimensionality, floor and ceiling effects, internal consistency, and reliability were examined. Differential item functioning was used to examine bias with respect to demographic and injury characteristics. Correlations with measures of related constructs (Community Integration Questionnaire, Satisfaction with Life Scale, Post-Traumatic Stress Checklist-Civilian, and Veteran's Rand-12) and known-group differences were examined.

RESULTS

Eight hundred and seventy-six burn survivors with moderate to severe injury from 6 months to 20 years postburn provided responses on PROMIS-29 domains. Participants' ages ranged from 18 years to 93 years at time of assessment; mean years since injury was 3.4. All PROMIS domain scores showed high internal consistency (Cronbach's α = 0.87-0.97). There was a large ceiling effect on ability to participate in social roles (39.7%) and physical function (43.3%). One-factor confirmatory factor analyses supported unidimensionality (all comparative fit indices >0.95). We found no statistically significant bias (differential item functioning). Reliability was high (>0.9) across trait levels for all domains except sleep, which reached moderate reliability (>0.85). All known-group differences by demographic and clinical characteristics were in the hypothesized direction and magnitude except burn size categories.

CONCLUSION

The results provide strong evidence for reliability and validity of PROMIS-29 domain scores among adult burn survivors. Reliability of the extreme scores could be increased and the ceiling effects reduced by administering PROMIS-43, which includes six items per domain, or by administering by computerized adaptive testing.

Nationwide enumeration of emergency operations performed in Ghana

PURPOSE

To determine the population-based rate of emergency surgery performed in Ghana, categorized by hospital level.

METHODS

Data on operations performed from June 2014 to May 2015 were obtained from a nationally representative sample of hospitals and scaled up to nationwide estimates. Operations were categorized as to: "emergency" or "elective" and as to "essential" (most cost-effective, highest population impact) or "other" according to the World Bank's Disease Control Priorities project.

RESULTS

Of 232,776 (95% UI 178,004-287,549) total operations performed nationally, 48% were emergencies. 112,036 emergency operations (95% UI 92,105-131,967) were performed and the annual national rate was 416 per 100,000 population (95% UI 342-489). Most emergency operations (87%) were in the essential category. Of essential emergency procedures, 47% were obstetric and gynecologic, 22% were general surgery, and 31% were trauma. District (first-level) hospitals performed 54%, regional hospitals 10%, and tertiary hospitals 36% of all emergency operations. About half (54%) of district hospitals did not have a fully trained surgeon, however, these hospitals performed 36% of district hospital emergency operations and 20% of all emergency operations.

CONCLUSIONS

Emergency operations make up nearly half of all operations performed in Ghana. Most are performed at district hospitals, many of which do not have fully trained surgeons. Obstetric procedures make up a large portion of emergency operations, indicating a need for improved provision of non-obstetric emergency surgical care. These data are useful for future benchmarking efforts to improve availability of emergency surgical care in Ghana and other low- and middle-income countries.
