Predictors of Discharge Disposition in Older Adults With Burns: A Study of the Burn Model Systems

A Narrative Review of Outcomes in Burn Rehabilitation Based on the International Classification of Functioning, Disability, and Health

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.

Inpatient Rehabilitation Following Burn Injury

Inpatient rehabilitation confers excellent benefit to burn survivors and should be considered as a potential destination during discharge planning. Consulting physiatrists identify and manage complications within the inpatient rehabilitation setting. Interventions can be taken to address medical sequelae of injury, including pain, itch, neuropathy, psychological coping and mood, and nutritional needs. Physiatrists also oversee and direct a rehabilitation program focusing on scar management, contracture prevention, dysphagia treatment, and evaluation and treatment of cognitive impairments. Aerobic and resistive exercise are key components of an inpatient rehabilitation program to reduce the systemic impact of a burn injury and improve quality of life.

Long-Term Outcomes in Burn Patients

Better understanding of long-term outcomes after burn injury is essential for the burn clinician. Contractures are present in almost half of patients at discharge. Although less common, neuropathy and heterotopic ossification may be missed or go unaddressed. Close attention to psychological distress and to challenges with community reentry is essential. Obviously long-term problems with skin issues occur but other issues must be attended to maximize health and quality of life after injury. Facilitating access to community resources and providing long-term medical follow-up should be the standard of care.

Short-term and long-term increased mortality in elderly patients with burn injury: a national longitudinal cohort study

BACKGROUND

The population of elderly patients with burn injuries is growing. Insight into long-term mortality rates of elderly after burn injury and predictors affecting outcome is limited. This study aimed to provide this information.

METHODS

A multicentre observational retrospective cohort study was conducted in all three Dutch burn centres. Patients aged ≥65 years, admitted with burn injuries between 2009 and 2018, were included. Data were retrieved from electronic patient records and the Dutch Burn Repository R3. Mortality rates and standardized mortality ratios (SMRs) were calculated. Multivariable logistic regression was used to assess predictors for in-hospital mortality and mortality after discharge at 1 year and five-year. Survival analysis was used to assess predictors of five-year mortality.

RESULTS

In total, 682/771 admitted patients were discharged. One-year and five-year mortality rates were 8.1 and 23.4%. The SMRs were 1.9(95%CI 1.5-2.5) and 1.4(95%CI 1.2-1.6), respectively. The SMRs were highest in patients aged 75-80 years at 1 year (SMRs 2.7, 95%CI 1.82-3.87) and five-year in patients aged 65-74 years (SMRs 10.1, 95%CI 7.7-13.0). Independent predictors for mortality at 1 year after discharge were higher age (OR 1.1, 95%CI 1.0-1.1), severe comorbidity, (ASA-score ≥ 3) (OR 4.8, 95%CI 2.3-9.7), and a non-home discharge location (OR 2.0, 95%CI 1.1-3.8). The relative risk of dying up to five-year was increased by age (HR 1.1, 95%CI 1.0-1.1), severe comorbidity (HR 2.3, 95%CI 1.6-3.5), and non-home discharge location (HR 2.1, 95%CI 1.4-3.2).

CONCLUSION

Long-term mortality until five-year after burn injury was higher than the age and sex-matched general Dutch population, and predicted by higher age, severe comorbidity, and a non-home discharge destination. Next to pre-injury characteristics, potential long-lasting systemic consequences on biological mechanisms following burn injuries probably play a role in increased mortality. Decreased health status makes patients more prone to burn injuries, leading to early death.

A National Analysis of Discharge Disposition in Older Adults with Burns-Estimating the Likelihood of Independence at Discharge

Whereas older age predicts higher burn mortality, the impact of age on discharge disposition is less well defined in older adults with burns. This investigation assesses the relationship between older age and discharge disposition after burns in a nationally representative sample. We queried the 2007 to 2015 National Trauma Data Bank for non-fatal burn hospitalizations in older adults. Pre-defined age categories were 55 to 64 years (working-age comparison group), 65 to 74 years (young-old), 75 to 84 years (middle-old), and 85+ years (old-old). Covariables included inhalation injury, comorbidities, burn total body surface area, injury mechanism, and race/ethnicity. Discharge to non-independent living (nursing home, rehabilitation, and other facilities) was the primary outcome. Logistic regression assessed the association between older age and discharge to non-independent living. There were 25,840 non-fatal burn hospitalizations in older adults during the study period. Working-age encounters comprised 53% of admissions, young-old accounted for 28%, middle-old comprised 15% and old-old comprised 4%. Discharge to non-independent living increased with burn TBSA and older age in survivors. Starting in young-old, the majority (65 %) of patients with burns ≥20% TBSA were discharged to non-independent living. Adjusted odd ratios for discharge to non-independent living were 2.0 for young-old, 3.3 for middle-old, and 5.6 for old-old patients, when compared with working-age patients (all P < .001). Older age strongly predicts non-independent discharge after acute burn hospitalization. Matrix analysis of discharge disposition indicates a stepwise rise in discharge to non-independent living with higher age and TBSA, providing a realistic discharge framework for treatment decisions and expectations about achieving independent living after burn hospitalization.

Self-reported health measures in burn survivors undergoing burn surgery following acute hospitalization: A burn model system national database investigation

INTRODUCTION

Health Related Quality of Life (HRQoL) surveys such as PROMIS-29 may facilitate shared decision-making regarding surgery after burn injury. We aimed to examine whether scar revision and contracture release surgery after index hospitalization was associated with differences in HRQoL.

METHODS

Patient and PROMIS-29 Profile v2.0 data were extracted from the Burn Model System (BMS) at 6-, 12-, and 24-months after burn. PROMIS-29 measures 7 health-related domains. Linear regression was performed to identify associations between independent burn patient variables (e.g. scar-related surgery) and PROMIS-29 scores. Socio-demographic and injury variables were analyzed using logistic regression to determine the likelihood of undergoing burn-related surgery.

RESULTS

Of 727 participants, 201 (27.6%) underwent ≥ 1 scar/contracture operation within 24 months of injury. Number of operations at index hospital admission and range of motion (ROM) deficit at discharge were correlated with an increased likelihood of undergoing subsequent scar/contracture surgery (p < 0.05). Participants undergoing scar/contracture surgery and those that were Medicaid insured reported significantly worse HRQoL for PROMIS domains: anxiety, depression, and fatigue (p < 0.05).

CONCLUSIONS

After adjusting for burn severity and available confounders, participants who underwent scar-related burn reconstructive surgery after index hospitalization reported overall worse Health-Related Quality of Life (HRQoL) in multiple domains.

Burn model system national longitudinal database representativeness by race, ethnicity, gender, and age

INTRODUCTION

Representativeness of research populations impacts the ability to extrapolate findings. The Burn Model System (BMS) National Database is one of the largest prospective, longitudinal, multi-center research repositories collecting patient-reported outcomes after burn injury.

OBJECTIVE

To assess if the BMS Database is representative of the population that is eligible to participate.

DESIGN

Data on adult burn survivors who were eligible for the BMS Database from 2015 to 2019 were analyzed.

SETTING

Not applicable.

PARTICIPANTS

Burn survivors treated at BMS centers meeting eligibility criteria for the BMS Database. Eligibility for the database is based on burn size and receipt of autografting surgery.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

Race, ethnicity, gender, and age were compared between individuals who did and did not enroll. Regression analysis examined the correlation between demographic characteristics and study enrollment. Additional regression analysis examined the association between enrollment and the intersection of race, ethnicity, and gender.

RESULTS

A total of 982 adult burn survivors were eligible for the BMS database during the study period. Of those who were eligible, 72.1% Enrolled and 27.9% were Not Enrolled. The Enrolled group included more female and more younger survivors compared to the Not Enrolled group. In regression analyses, Black/African American burn survivors were less likely and individuals identifying as female were more likely to enroll in the BMS Database. Furthermore, White men and women were more likely to enroll compared to Black/African American men and women, and non-Hispanic/Latino men were more likely to enroll compared to Hispanic/Latino men.

CONCLUSIONS

This study found differences in BMS Database enrollment by race, ethnicity, and gender. Further research is warranted to investigate causes for the disparities found in this study. In addition, strategies are needed to improve enrollment to ensure future representativeness.

The predictive validity of the Functional Assessment for Burns - Critical Care (FAB-CC) score for discharge outcomes in major burns

INTRODUCTION

Physical function scoring of burn ICU patients is recommended but currently validated scores are lacking.

OBJECTIVE

To evaluate the predictive validity of the FAB -CC for burn ICU patients' discharge outcome.

METHODS

All patients underwent daily exercise and FAB -CC screen if they were stable. Two FAB-CC scores were performed; FAB-CC1 on the first day the patient passed the FAB-CC screen, FAB-CC2 within 48 h before ICU discharge. Hospital discharge outcome was defined as transfer for further inpatient rehabilitation or home with social care versus home with no social care. 76 patients' data were entered into the analyses. We used multiple logistic regression analysis to identify variables that predict discharge outcome.

RESULTS

Increasing patient age (p = 0.001), duration of ventilation (p = 0.0003), ICU Length of stay (LOS) (p = 0.0001), total hospital LOS (p < 0.0001), presence of cardiopulmonary disease (p = 0.008), neurological disorder (p = 0.0003) and psychiatric illness (p = 0.003) are positively associated with transfer for inpatient rehabilitation or home with social care. Increasing FAB-CC1 (p < 0.0001) and FAB -CC2 (p = 0.0001) are negatively associated with transfer for inpatient rehabilitation or home with social care. The most predictive model for discharge outcome combined the variables patient age, FAB-CC1, FAB-CC2 and psychiatric illness. Patient age (p = 0.01), FAB-CC1 (p = 0.02) and psychiatric illness (p = 0.009) independently predict discharge outcome.

CONCLUSIONS

FAB-CC2 is associated with, and FAB-CC1 has predictive validity for, patient hospital discharge outcome. These findings, in conjunction with our earlier work, confirm clinical utility of the FAB-CC for burns ICU patients.

Burns in the elderly: a nationwide study on management and clinical outcomes

Background

In modern-day burn care, advanced age remains an important predictor for mortality among burn victims. In this study, we compared the complete treatment trajectory (including pre-hospital and surgical treatment) and the outcomes between an elderly burn population and a younger adult burn population.

Methods

In this nationwide study, data from the Dutch Burn Repository were used. This is a uniform national registration for Dutch specialized burn care. All adult patients that were admitted to one of the three Dutch burn centres from the period 2009 to 2015 were included in the analysis. Burn patients were considered as elderly when ≥65 years of age, and were then further subdivided into three age categories: 65-74, 75-85 and 85+ years. Younger adults in the age category 18-64 years were used as the reference group.Surgical management was studied comprehensively and included timing of surgery, the number of procedures and details on the surgical technique, especially the technique used for debridement and the grafting technique that was applied.For the comparison of clinical outcome, the following parameters were included: mortality, wound infections, length of stay/TBSA (total body surface area) burned, discharge disposition and secondary reconstructions.

Results

During the study period, 3155 adult patients were included (elderly, n = 505). Burn severity, reflected by the median TBSA, varied between 3.2-4.0% and was comparable, but aetiology and pre-hospital care were different between elderly and the younger adult reference group.Surgical treatment was initiated significantly faster in elderly burn patients (p < 0.001). Less selective techniques for surgical debridement were used in the elderly burns patients (hydrosurgery, 42.0% vs 23.5-22.6%), and on the other hand more avulsion (5.3% vs 7.3-17.6%) and primary wound closure (6.7% vs 24.5%). The most frequently used grafting technique was meshed skin grafts (79.2-88.6%); this was not related to age.Mortality increased rapidly with a higher age and showed a high peak in the 85+ category (23.8%). Furthermore, considerable differences were found in hospital discharge disposition between the elderly and the reference group.

Conclusions

In conclusion, elderly burn patients who require specialized burn care are vulnerable and medically challenging. Differences in aetiology, comorbidity, physiology and the management prior to admission possibly affect the initial surgical management and result in significantly worse outcomes in elderly. Elderly patients need optimal, timely and specialized burn care to enhance survival after burn injuries.

Amputation Following Burn Injury

Amputation following burn injury is rare. Previous studies describe the risk of amputation after electrical burn injuries. Therefore, we describe the distribution of amputations and evaluate risk factors for amputation following burn injury at a large regional burn center. We conducted a retrospective analysis of patients ≥17 years admitted from January 2002 to December 2015. Patients who did and did not undergo an amputation procedure were compared. A multivariate logistic regression model was used to determine the risk factors for amputation. Amputations were further categorized by extremity location and type (major, minor) for comparison. Of the 8313 patients included for analysis, 1.4% had at least one amputation (n = 119). Amputees were older (46.7 ± 17.4 years) than nonamputees (42.6 ± 16.8 years; P = .009). The majority of amputees were white (47.9%) followed by black (39.5%) when compared with nonamputees (white: 57.1%, black: 27.3%; P = .012). The most common burn etiology for amputees was flame (41.2%) followed by electrical (23.5%) and other (21.9%). Black race (odds ratio [OR]: 2.29; 95% confidence interval [CI]: 1.22-4.30; P = .010), electric (OR: 13.54; 95% CI: 6.23-29.45; P < .001) and increased %TBSA (OR: 1.03; 95% CI: 1.02-1.05; P < .001) were associated with amputation. Burn etiology, the presence of preexisting comorbidities, black race, and increased %TBSA increase the odds of post burn injury. The role of race on the risk of amputation requires further study.

Rehabilitation of the Complex Burn Patient with Multiple Injuries or Comorbidities

Patients with complex burn injuries require interdisciplinary rehabilitation to maximize their functional recovery. Successful rehabilitation from burn injuries starts with addressing the loss of the protective, mechanical, and cosmetic function of the skin and underlying structures. However, other injuries, particularly to the nervous and musculoskeletal systems, need to be identified and managed as part of the rehabilitation plan. Burn injuries can cause losses of functional mobility, self-care skills, psychological well-being, and community participation, which require comprehensive rehabilitation interventions throughout the recovery process.
