ABSTRACT

Burn reconstruction outcomes are an area of growing investigation. Although there is evidence of measured physical improvements in scar characteristics after laser treatment, there is little information on patient reported outcomes. The purpose of this study is to compare patient reported outcomes between burn survivors with and without laser treatment. The study included participants in the Burn Model Systems National Database at a single center; participants that received outpatient laser treatment for burn scars were compared to a matched group of burn survivors that did not receive laser. The following outcomes were examined: Satisfaction With Life Scale, Mental and Physical Component Summary of the Veterans Rand Survey, and the PROMIS Pain Intensity Scale. Regression analyses examined the associations between laser treatment and each outcome at 12 and 24 months. The study population included 287 adult burn survivors (65 laser group, 222 control group). The significant differences found between the two groups included: burn size (laser: 14.9, 13.5 SD, control: 8.9, 11.1 SD; p<0.001), insurance type (p=0.036), inhalation injury (laser: 17.2%, control: 2.7%; p<0.001), and ventilator requirement (laser: 27.7%, control: 13.5%; p=0.013). Laser treatment was not associated with any of the outcomes at both follow-up time points. Further research is needed to develop patient reported outcome measures that are more sensitive to the clinical changes experienced by burn survivors receiving laser treatment.

ABSTRACT

Cerebral organoids (COs) are a valuable tool to study the intricate interplay between glial cells and neurons in brain development and disease, including HIV-associated neuroinflammation. We developed a novel approach to generate microglia containing COs (CO-iMs) by co-culturing hematopoietic progenitors and induced pluripotent stem cells. This approach allowed for the differentiation of microglia within the organoids concomitantly to the neuronal progenitors. CO- iMs exhibited higher efficiency in generation of CD45 + /CD11b + /Iba-1 + microglia cells compared to conventional COs with physiologically relevant proportion of microglia (∼7%). CO-iMs exhibited substantially higher expression of microglial homeostatic and sensome markers as well as markers for the complement cascade. CO-iMs showed susceptibility to HIV infection resulting in a significant increase in several pro-inflammatory cytokines/chemokines and compromised neuronal function, which were abrogated by addition of antiretrovirals. Thus, CO-iM is a robust model to decipher neuropathogenesis, neurological disorders, and viral infections of brain cells in a 3D culture system.

ABSTRACT

INTRODUCTION: An area of rehabilitation research in burns is the impact of co-morbidities on disease trajectory. Obesity is a comorbidity of increasing public health concern, but its role remains controversial regarding burn injury and physical recovery. Our aim was to evaluate the association between body mass index (BMI) categories as a measure of obesity at discharge and self-reported physical function (PF) during recovery of adult burn survivors. METHODS: This is a retrospective study on data collected by four major US burn centers, which contribute to the Burn Model System National Database. The data included BMI obtained at hospital discharge and self-reported PF-mobility, using the PROMIS measures assessed at 6, 12, and 24 months after burn. Subjects were classified into weight status categories based on BMI: underweight (BMI <18.5), normal weight (18.5 ≤ BMI <25), overweight (25 ≤ BMI <30), obesity class 1 (30 ≤ BMI <35), obesity class 2 (35 ≤ BMI <40), and obesity class 3 (BMI ≥40). Mixed-effects linear regression models were used to assess the association between BMI categories and PF scores over time, adjusted for patient and injury characteristics. RESULTS: A total of 496 adult burn patients aged 47 ± 16 years were included, with mean total body surface area (TBSA) burned of 18 ± 19 % and mean BMI at discharge of 28 ± 7 kg/m2. PROMIS PF scores significantly improved over time in the recovery phase after burn (time effect, p < 0.001). Compared to overweight burn patients, normal-underweights exhibited lower PF score by an average of 4.06 units (p = 0.001) but scores increased linearly by an estimated 0.17 units per month (p = 0.01) over the 24 months after discharge. Similarly, compared to overweight burn patients, class 1 obese reported lower PF score by a mean 2.67 units (p = 0.07) but PF increased linearly by 0.15 units per month (p = 0.07) over the 24 months after discharge. These findings were independent of the effects of age at discharge, sex, TBSA burned, and hand and leg burn. CONCLUSION: Being overweight was associated with improved and faster recovery of PF scores compared to normal, underweight, and obese burn patients during long-term recovery. Hence, our data suggests that long-term recovery and restoration of PF in adult burn survivors is not compromised by a small excess in body weight.

ABSTRACT

OBJECTIVE: Pain is common in inpatient rehabilitation patients; however, the prevalence of pain diagnoses in this population is not well-defined. This study examines comorbid pain diagnoses in inpatient rehabilitation patients across impairment groups. DESIGN: Adult inpatient rehabilitation patients discharged from January 2016 through December 2019 were identified in the Uniform Data System for Medical Rehabilitation® database using a literature-established framework containing ICD-10-CM pain diagnoses. Demographic data, clinical data, and pain diagnoses were compared across the 17 rehabilitation impairment groups. RESULTS: Of 1,925,002 patients identified, 1,347,239 (70.0%) had at least one ICD-10 pain diagnosis. Over half of all patients in each impairment group had at least one pain diagnosis. The most common pain diagnoses were limb/extremity and joint pain, with variation between impairment groups. Female sex and being in the arthritis, major multiple trauma, and pain syndrome impairment groups were associated with a greater odds of a pain diagnosis. CONCLUSION: Over half of all patients in each rehabilitation impairment group have a pain diagnosis, which varies between impairment groups. Due to the high prevalence of pain diagnoses, a new focus on pain management in inpatient rehabilitation patients is needed. Rehabilitation outcomes may also be affected by pain.

ABSTRACT

ABSTRACT: Trauma centers demonstrate an impressive ability to save lives, as reflected by inpatient survival rates of over 95% in the United States. Nevertheless, we fail to allocate sufficient effort and resources to ensure that survivors and their families receive the necessary care and support after leaving the trauma center. The objective of this scoping review is to systematically map the research on collaborative care models (CCM) that have been put forward to improve trauma survivorship. Of 833 articles screened, we included 16 studies evaluating eight collaborative care programs, predominantly in the U.S. The majority of the programs offered care coordination and averaged 9-months in duration. Three-fourths of the programs incorporated a mental health provider within their primary team. Observed outcomes were diverse: some models showed increased engagement (e.g., Center for Trauma Survivorship, trauma quality-of-life follow-up clinic), while others presented mixed mental health outcomes and varied results on pain and healthcare utilization. The findings of this study indicate that collaborative interventions may be effective in mental health screening, PTSD and depression management, effective referrals, and improving patient satisfaction with care. A consensus on core elements and cost-effectiveness of CCMs is necessary to set the standard for comprehensive care in post-trauma recovery.

ABSTRACT

The blood-brain barrier (BBB) is one of several barriers between the brain and the peripheral blood system to maintain homeostasis. Understanding the interactions between infectious agents such as human immunodeficiency virus type 1 (HIV-1), which are capable of traversing the BBB and causing neuroinflammation requires modeling an authentic BBB in vitro. Such an in vitro BBB model also helps develop means of targeting viruses that reside in the brain via natural immune effectors such as antibodies. The BBB consists of human brain microvascular endothelial cells (HBMECs), astrocytes, and pericytes. Here we report in vitro methods to establish a dual-cell BBB model consisting of primary HBMECs and primary astrocytes to measure the integrity of the BBB and antibody penetration of the BBB, as well as a method to establish a single cell BBB model to study the impact of HIV-1 infected medium on the integrity of such a BBB.

ABSTRACT

OBJECTIVE: To examine the moderation effects of daily behavior on the associations between symptoms and social participation outcomes after burn injury. DESIGN: A 6-month prospective cohort study. SETTING: Community. PARTICIPANTS: Twenty-four adult burn survivors. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Symptoms and social participation outcomes were assessed weekly using smartphone surveys, including symptoms of pain (Patient-Reported Outcomes Measurement Information System [PROMIS] Pain Intensity and Pain Interference), anxiety (PROMIS Anxiety), and depression (Patient Health Questionnaire), as well as outcomes of social interactions and social activities (Life Impact Burn Recovery Evaluation [LIBRE] Social Interactions and Social Activities). Daily behaviors were automatically recorded by a smartphone application and smartphone logs, including physical activity (steps, travel miles, and activity minutes), sleep (sleep hours), and social contact (number of phone calls and message contacts). RESULTS: Multilevel models controlling for demographic and burn injury variables examined the associations between symptoms and social participation outcomes and the moderation effects of daily behaviors. Lower (worse) LIBRE Social Interactions and LIBRE Social Activities scores were significantly associated with higher (worse) PROMIS Pain Intensity, PROMIS Pain Interference, PROMIS Anxiety, and Patient Health Questionnaire-8 scores (P<.05). Additionally, daily steps and activity minutes were associated with LIBRE Social Interactions and LIBRE Social Activities (P<.05), and significantly moderated the association between PROMIS Anxiety and LIBRE Social Activities (P<.001). CONCLUSIONS: Social participation outcomes are associated with pain, anxiety, and depression symptoms after burn injury, and are buffered by daily physical activity. Future intervention studies should examine physical activity promotion to improve social recovery after burns.

ABSTRACT

Gastric hyperplastic polyps (GHP) are one of the most common gastric epithelial polyps. They are generally asymptomatic and often discovered incidentally during endoscopic procedures. In this article, we present the case of a 36-year-old patient with dyspepsia attributed to the prolapse of a large gastric hyperplastic polyp with extensive xanthomatous change. The endoscopic findings revealed that the motion of the large polyp caused an intermittent pyloric obstruction. The large polyp was removed through a successful snare polypectomy, resolving the patient's symptoms. While dyspepsia is predominantly associated with functional causes, it is crucial to consider structural factors like GHP, particularly in the case of large polyps, as part of the differential diagnosis.

ABSTRACT

Patients with a history of blood clots are commonly placed on anticoagulation therapy, but a common adverse effect of this therapy is hemorrhage. Our patient with a history of left ventricle thrombus in a free-standing inpatient rehabilitation hospital had ecchymoses that expanded over a large portion of the posterior thigh in one day. The rapid expansion of the ecchymoses coupled with a decline in hemoglobin levels prompted an immediate evaluation that showed an intramuscular hematoma. With hemoglobin levels dropping significantly, the patient was then transferred to the emergency department for higher levels of care. A multidisciplinary team of vascular surgery and electrophysiology physicians decided to discontinue anticoagulation and monitor the hematoma with serial compartment checks. The hematoma had stabilized throughout the hospital stay without surgical intervention. This case will discuss the difficulty of managing a patient with a history of previous blood clots with an adductor magnus hematoma in the setting of concurrent iatrogenic anticoagulation. Furthermore, we will review the current management and evaluation of intramuscular hematomas.

ABSTRACT

OBJECTIVE: This study attempts to examine long-term pain medication usage after burn injury and its association with functional and psychosocial outcomes. DESIGN: This is a multi-center retrospective cohort study utilizing the Burn Model System National Longitudinal Database. Participants injured from 2015 to 2021 were divided into two groups, those taking and not taking prescription pain medication at 12 months after injury. Regression analyses examined associations between pain medication use and outcomes at 12 months, adjusting for demographics, burn size, length of hospital stay, and pre-injury pain medication use and employment status. Outcomes included VR-12 Physical and Mental Component Summary scores (PCS and MCS), Patient-Reported Outcomes Measurement Information System (PROMIS-29) Anxiety and Depression scores, Satisfaction with Life Scale (SWLS), and employment status. RESULTS: Of 358 participants analyzed, prescription pain medication use was associated with worse outcomes at 12 months: PCS (ß = -7.11, p < 0.001), MCS (ß = -6.01, p < 0.001), and PROMIS-29 Depression (ß = 4.88, p < 0.001) and Anxiety (ß = 6.16, p < 0.001). SWLS was not significantly associated with pain medication use (p = 0.069) and those taking pain medication were 52% less likely to be employed at 12 months (p = 0.035). CONCLUSION: There is a significant association between prescription pain medication use and worse physical, mental, and employment outcomes at 12 months after burn injury.

ABSTRACT

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. LEVEL OF EVIDENCE: 2b TYPE OF STUDY: Symptom Prevalence Study.

ABSTRACT

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 (ß=-0.27, P<.001) and 12 months (ß=-0.39, P<.001), and PROMIS-29 Pain Interference at 6 months (ß=-0.20, P<.01). For LIBRE Social Activities, significant predictors consisted of the PROMIS-29 Depression at 6 months (ß=-0.37, P<.001) and 12 months (ß=-0.37, P<.001), PROMIS-29 Pain Interference at 6 months (ß=-0.40, P<.001) and 12 months (ß=-0.37, P<.001), and Heat Intolerance at 12 months (ß=-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.

ABSTRACT

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.

ABSTRACT

Physical, social, and psychological outcomes have been identified as relevant to the rehabilitation process of children with burn injuries. Existing legacy measures are limited in item content and only cover a few constructs. Condition-specific outcomes are highly relevant to gauge early growth and development. Computerized adaptive tests (CATs) leveraging advanced psychometric technologies minimize respondent burden. This project developed PS-LIBRE1-5 Profile CAT (Preschool Life Impact Burn Recovery Evaluation) to measure relevant postburn outcomes in children aged one to five. Responses to the field-tested PS-LIBRE1-5 Profile (188 items) were measured on a scale of frequency or ability. Scores were coded from 0 to 4 where higher scores reflected better functioning. Factor analysis identified the items retained in the final item bank of each scale. CAT simulations were conducted to estimate the mean score of each scale. The simulated CAT score and full item bank scores were compared based upon the score range, ceiling and floor effects, and marginal reliabilities. The child mean age was 3.0 ± 1.5 years (n = 500). Average burn size and time since burn injury were 4.2% TBSA and 1.1 years, respectively. Psychometric analysis resulted in eight scales: Physical, Communication and Language, Emotional Wellbeing, Mood, Anxiety, Peer Acceptance, Play, and Peer Relations. Ceiling effects were acceptable at <13% for all scales. Marginal reliabilities of the CATs were credible. The PS-LIBRE1-5 Profile CAT contains 111 items, and is a comprehensive measure that captures physical, communication and language, psychological, and social functioning of preschool burn survivors.

ABSTRACT

OBJECTIVE: The aim of this study was to address the limited understanding of neuropathic pain (NP) among burn survivors by comprehensively examining its prevalence and related factors on a national scale using the Burn Model System (BMS) National Database. BACKGROUND: NP is a common but underexplored complaint among burn survivors, greatly affecting their quality of life and functionality well beyond the initial injury. Existing data on NP and its consequences in burn survivors are limited to select single-institution studies, lacking a comprehensive national perspective. METHODS: The BMS National Database was queried to identify burn patients responding to NP-related questions at enrollment, 6 months, 12 months, 2 years, and 5 years postinjury. Descriptive statistics and regression analyses were used to explore associations between demographic/clinical characteristics and self-reported NP at different time points. RESULTS: There were 915 patients included for analysis. At discharge, 66.5% of patients experienced NP in their burn scars. Those with NP had significantly higher Patient-Reported Outcomes Measurement Information System 29 (PROMIS-29) pain inference, itch, anxiety, depression, and sleep disturbance scores and were less able to partake in social roles. Multiple logistic regression revealed male sex, % total body surface area, and moderate-to-severe pain as predictors of NP at 6 months. At 12 months, % total body surface area and moderate-to-severe pain remained significant predictors, while ethnicity and employment status emerged as significant predictors at 24 months. CONCLUSIONS: This study highlights the significant prevalence of NP in burn patients and its adverse impacts on their physical, psychological, and social well-being. The findings underscore the necessity of a comprehensive approach to NP treatment, addressing both physical symptoms and psychosocial factors.

ABSTRACT

Burn injury commonly causes long-term physical impairments and psychosocial limitations that impact survivorship. This article uses the World Health Organization (WHO) International Classification of Functioning, Disability and Health (ICF) framework to summarize burn rehabilitation outcomes related to body functions and structures and how they relate to activities and participation within the social context. This article will contribute to a better understanding of burn recovery, facilitate the identification of specific and meaningful issues common to burn survivorship that may be under-reported in prior investigations and guide future rehabilitation to advance long-term burn outcomes.

ABSTRACT

Prostate cancers adapt to androgen receptor (AR) pathway inhibitors and progress to castration resistance due to ongoing AR expression and function. To counter this, we developed a new approach to modulate the AR and inhibit castration-resistant prostate cancer (CRPC) using multivalent peptoid conjugates (MPC) that contain multiple copies of the AR-targeting ligand ethisterone attached to a peptidomimetic scaffold. Here, we investigated the antitumor effects of compound MPC309, a trivalent display of ethisterone conjugated to a peptoid oligomer backbone that binds to the AR with nanomolar affinity. MPC309 exhibited potent antiproliferative effects on various enzalutamide-resistant prostate cancer models, including those with AR splice variants, ligand-binding mutations, and noncanonical AR gene expression programs, as well as mouse prostate organoids harboring defined genetic alterations that mimic lethal human prostate cancer subtypes. MPC309 is taken up by cells through macropinocytosis, an endocytic process more prevalent in cancer cells than in normal ones, thus providing an opportunity to target tumors selectively. MPC309 triggers a distinct AR transcriptome compared with DHT and enzalutamide, a clinically used antiandrogen. Specifically, MPC309 enhances the expression of differentiation genes while reducing the expression of genes needed for cell division and metabolism. Mechanistically, MPC309 increases AR chromatin occupancy and alters AR interactions with coregulatory proteins in a pattern distinct from DHT. In xenograft studies, MPC309 produced significantly greater tumor suppression than enzalutamide. Altogether, MPC309 represents a promising new AR modulator that can combat resistant disease by promoting an AR antiproliferative gene expression program.

ABSTRACT

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.

ABSTRACT

Social determinants of medical education are the most impactful aspects of recruiting, retaining, and producing the next generation of a diverse physician workforce. We can use the same framework well known to describe social determinants of health to identify social determinants that impact medical education learners and their ability to enter the workforce and succeed to completion. Efforts aimed at recruitment and retention should not exist in isolation and must be matched with those that continuously assess and evaluate the learning environment. The development of a climate where all can bring their full selves to learn, study, work, and care for patients is critically important in the creation of a learning environment where every participant can grow and thrive. If we are to address the need to diversify the workforce, we must be intentional with strategic plans, which includes addressing the social determinants that are prohibitive for some of our learners.

ABSTRACT

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.
