Contractures in burn injury: defining the problem.

This study prospectively examined the incidence and severity of large joint contractures after burn injury and determined predictors of contracture development. Data were collected prospectively from 1993 to 2002 for consecutive adult burn survivors admitted to a regional burn center. Demographic and medical data were collected on each subject. The primary outcome measures included the presence of contractures, number of contractures per patient, and severity of contractures at each of four joints (shoulder, elbow, hip, knee) at time of hospital discharge. Logistic regression analysis was performed to determine predictors of the presence and severity of contractures and a negative binomial regression was performed to determine predictors of the number of contractures. Of the 985 study patients, 381 (38.7%) developed at least one contracture at hospital discharge. Among those with at least one contracture, the mean is three contractures per person. The shoulder was the most frequently contracted joint (38%), followed by the elbow (34%) and knee (22%). Most contractures were mild (60%) or moderate (32%) in severity. Statistically significant predictors of contracture development were length of stay (P < .005) and extent of burn (P = .033) and graft (P < .005). Predictors of the severity of contracture include graft size (P < .005), amputation (P = .034), and inhalation injury (P = .036). More than one third of the patients with a major burn injury developed a contracture at hospital discharge, which highlights the importance of therapeutic positioning and intensive therapy intervention during acute hospitalization. Furthermore, this challenges the burn care community to find new and better ways of preventing contractures after burn injury.

A descriptive review of neuropathic-like pain after burn injury

This study reviews the natural history of neuropathic-like pain after burn injury. We undertook a retrospective chart review during a 24-month period of patients treated at an outpatient burn center. The medical records of patients with neuropathic-like pain complaints, including the sensation of pins and needles, burning, stabbing, shooting, or “electric” sensations, were included for analysis. Medical and demographic data were collected. We identified 72 patients for inclusion in the study. The age was 44 ± 2 years (mean ± SEM), and TBSA burned was 18 ± 3%. The first complaint of neuropathic-like symptoms was at 4.3 ± 0.5 months after injury. Documentation of improvement in the symptoms occurred at 7.0 ± 0.8 months. Symptoms persisted for 13.1 ± 2.2 months after the injury. Patients were followed for 14.5 ± 2.2 months. Documented initial pain severity score was 7 ± 1 of 10. Typical exacerbating factors included temperature change, dependent position, light touch, and weight-bearing activities. Common alleviating factors included rest, massage, compression garment use, and elevation. Treatment regimens often included gabapentin (38%) and steroid injections (21%). Hypertrophic scarring (43%), pruritis (40%), and psychiatric diagnoses (36%) were common associated problems. There is a patterned natural history for neuropathic-like pain after burn injury. This clinical entity involves significant pain complaints and persists, on average, for greater than 1 year after injury, which underscores the importance of long-term outpatient care after burn injury. Furthermore, an understanding of the natural history will assist clinicians in prognosticating and caring for burn survivors with pain after wound closure.

Contractures in burn injury part II: investigating joints of the hand.

This study prospectively examines the incidence and severity of hand contractures after burn injury and determines predictors of contracture development. Data were collected prospectively from 1993 to 2002 for adult burn survivors admitted to a regional burn center. Demographic and medical data were collected on each subject. Primary outcome measures include presence of contractures, number of contractures, and the severity of contractures at each of the hand joints at hospital discharge. The metacarpal-phalangeal, proximal inter-phalangeal (PIP), and distal inter-phalangeal joints of all digits and the wrist joints are included in this study. Regression analysis was performed to determine predictors of the presence, severity, and number of contractures. Of the 985 study patients, 23% demonstrated at least one hand contracture at hospital discharge. Those with a contracture averaged ten contractures per person. Most contractures were mild (48%) or moderate (41%) in severity. The wrist was the most frequently affected joint (22%). Statistically significant predictors of contracture development include concomitant medical problems, total body surface area grafted and presence of hand burn and hand grafting (P < .05). Predictors of the number of contractures include length of stay, concomitant medical problems, burn size and presence of hand burn and grafting (P < .05). Contractures of the hand are a significant complication of burn injury. Clinicians can use the contracture predictors to help target interventions for those patients most at risk of developing hand contractures. Given the functional importance of the hand in daily living, the burn care community is challenged to find new ways of preventing and treating hand contractures.

Barriers Impacting Employment After Burn Injury

This study investigates the barriers to return to work after burn injury. The electronic records of burn survivors treated at a Regional Burn Center outpatient clinic from 2001 to 2007 were retrospectively reviewed. Inclusion criteria included employment at the time of burn injury and age 18 years or older. Documentation of barriers to return to work were reviewed and classified into eight categories. Logistic regression analysis was used to determine predictors of return to work at more than 1 year. Ordered logistic regression analysis was performed to determine barrier predictors of employment. The authors identified 197 patients for inclusion in the study. The age was 37 ± 0.8 (mean ± SEM) and total body surface area burned was 16 ± 1.3%. Two thirds (n = 132) of subjects returned to work by 1 year. The most common barriers included pain (n = 79), neurologic problems (n = 69), impaired mobility (n = 58), and psychiatric issues (n = 51). Pain was the most frequent barrier to return to work at all time intervals. Significant predictors of return to work at more than 12 months included length of hospital stay, inpatient rehabilitation, electric etiology, and burn at work (P < .05). Impaired mobility was a statistically significant (P < .05) barrier and other medical issues showed a trend toward statistical significance (P = .054) in predicting return to work at more than 12 months. There are many barriers that impede return to work in the burn population, including pain, neurologic problems, impaired mobility, and psychiatric issues. Early identification of those at risk for prolonged unemployment should prompt expeditious referral to comprehensive rehabilitation services that include work hardening and vocational training programs.

Effect of implementation of safety measures in tae kwon do competition

Background: Previous reviews of tae kwon do (TKD) tournaments have documented injury rates of 25/1000 to 12.7/100 athlete exposures. Most injuries have been reported to be to the head and the neck and are occasionally very serious. Many of these studies involved high level TKD competitions with minimal safety precautions. Recently, safety measures have been implemented in many TKD competitions. Objective: To evaluate retrospectively the incidence of injuries in TKD competitions involving a wide range of participants and featuring extensive safety precautions. Methods: A total of 2498 participants ranged in age from 18 to 66, included both men and women, and ranged in rank from yellow to black belt. Traumas, defined as any event requiring interaction with medical staff, were documented with respect to mechanism, diagnosis, treatment, and follow up recommendations. An injury was defined as a trauma that prevented a contestant from resuming competition on the day that the trauma occurred, according to National Collegiate Athletic Association criteria. Results: The injury rate was 0.4/1000 athlete exposures. This is lower than reported in previous studies of TKD tournaments and in many other sports. Conclusion: TKD tournaments that emphasise limited contact, protective equipment, and medical supervision are relatively safe and compare favourably with other sports.

Functional Status Outperforms Comorbidities in Predicting Acute Care Readmissions in Medically Complex Patients

ObjectiveTo examine functional status versus medical comorbidities as predictors of acute care readmissions in medically complex patients.DesignRetrospective database study.SettingU.S. inpatient rehabilitation facilities.ParticipantsSubjects included 120,957 patients in the Uniform Data System for Medical Rehabilitation admitted to inpatient rehabilitation facilities under the medically complex impairment group code between 2002 and 2011.InterventionsA Basic Model based on gender and functional status was developed using logistic regression to predict the odds of 3-, 7-, and 30-day readmission from inpatient rehabilitation facilities to acute care hospitals. Functional status was measured by the FIM® motor score. The Basic Model was compared to six other predictive models—three Basic Plus Models that added a comorbidity measure to the Basic Model and three Gender-Comorbidity Models that included only gender and a comorbidity measure. The three comorbidity measures used were the Elixhauser index, Deyo-Charlson index, and Medicare comorbidity tier system. The c-statistic was the primary measure of model performance.Main Outcome MeasuresWe investigated 3-, 7-, and 30-day readmission to acute care hospitals from inpatient rehabilitation facilities.ResultsBasic Model c-statistics predicting 3-, 7-, and 30-day readmissions were 0.69, 0.64, and 0.65, respectively. The best-performing Basic Plus Model (Basic+Elixhauser) c-statistics were only 0.02 better than the Basic Model, and the best-performing Gender-Comorbidity Model (Gender+Elixhauser) c-statistics were more than 0.07 worse than the Basic Model.ConclusionsReadmission models based on functional status consistently outperform models based on medical comorbidities. There is opportunity to improve current national readmission risk models to more accurately predict readmissions by incorporating functional data.

Benchmarks for multidimensional recovery after burn injury in young adults: The development, validation, and testing of the american burn association/shriners hospitals for children young adult burn outcome questionnaire

Although data exist on burn survival, there are little data on long-term burn recovery. Patient-centered health outcomes are useful in monitoring and predicting recovery and evaluating treatments. An outcome questionnaire for young adult burn survivors was developed and tested. This 5-year (2003–2008) prospective, controlled, multicenter study included burned and nonburned adults ages 19 to 30 years. The Young Adult Burn Outcome Questionnaires were completed at initial contact, 10 days, and 6 and 12 months. Factor analysis established construct validity. Reliability assessments used Cronbach &agr; and test-retest. Recovery patterns were investigated using generalized linear models, with generalized estimating equations using mixed models and random effects. Burned (n = 153) and nonburned subjects (n = 112) completed 620 questionnaires (47 items). Time from injury to first questionnaire administration was 157 ± 36 days (mean ± SEM). Factor analysis included 15 factors: Physical Function, Fine Motor Function, Pain, Itch, Social Function Limited by Physical Function, Perceived Appearance, Social Function Limited by Appearance, Sexual Function, Emotion, Family Function, Family Concern, Satisfaction With Symptom Relief, Satisfaction With Role, Work Reintegration, and Religion. Cronbach &agr; ranged from 0.72 to 0.92, with 11 scales >0.8. Test-retest reliability ranged from 0.29 to 0.94, suggesting changes in underlying health status after burns. Recovery curves in five domains, Itch, Perceived Appearance, Social Function Limited by Appearance, Family Concern, and Satisfaction with Symptom Relief, remained below the reference group at 24 months. The Young Adult Burn Outcome Questionnaire is a reliable and valid instrument for multidimensional functional outcomes assessment. Recovery in some domains was incomplete.

Predictors of transfer from rehabilitation to acute care in burn injuries.

BACKGROUND Transfer to acute care from rehabilitation represents an interruption in a patient’s recovery and a potential deficiency in quality of care. The objective of this study was to examine predictors of transfer to acute care in the inpatient burn rehabilitation population. METHODS Data are obtained from Uniform Data System for Medical Rehabilitation from 2002 to 2010 for patients with a primary diagnosis of burn injury. Predictor variables include demographic, medical, and facility data. Descriptive statistics are calculated for acute and nonacute transfer patients. Logistic regression analysis is used to determine significant predictors of acute transfer within the first 3 days. A scoring system is developed to determine the risk of acute transfer. RESULTS There were 78 acute transfers in the first 3 days of a total of 4,572 burn admissions. Functional level at admission, age, and admission classification are significant predictors of transfer to acute care (p < 0.05). Total body surface area burned and medical comorbidities were not significantly associated with acute transfer risk. A 12-point acute transfer risk scoring system was developed, which demonstrates validity. CONCLUSION Efforts to reduce readmissions to acute care should include greater scrutiny of older, lower-functioning patients with burn injury who are evaluated for admission to inpatient rehabilitation. This acute transfer scoring system may be useful to clinicians, health care institutions, and policymakers to help predict those patients at highest risk for early transfer to the acute hospital from rehabilitation. LEVEL OF EVIDENCE Prognostic/diagnostic study, level II.

Outcomes and predictors in burn rehabilitation.

Advances in burn care in recent decades have resulted in a growing population of burn survivors and an increased need for inpatient rehabilitation. Burn survivors who require inpatient rehabilitation typically experience severe and complicated injuries. The purpose of this study is to examine burn rehabilitation outcomes and their predictor variables. Data are obtained from the Uniform Data System for Medical Rehabilitation from 2002 to 2007. Inclusion criterion is primary diagnosis of burn injury. Predictor variables include demographic, medical, and facility data. Outcome measures are length of stay efficiency, FIM® gain, community discharge, and FIM® discharge of at least 78. Linear and logistic regression analyses are used to determine significant predictors of outcomes. There are 2920 patients who meet inclusion criteria. The mean age of the population is 51 years, 33% of the population is female, 73% is Caucasian, and 40% are married. The median TBSA decile is 20 to 29%. The population exhibits a mean FIM® gain of 28 and length of stay efficiency of 2.1. A majority of the population is discharged to the community (76%) and has a FIM® discharge of at least 78 (81%). Significant predictors of outcomes in burn rehabilitation include age, FIM® admission, onset days, employment status, and marital status. Inpatient rehabilitation is critical to community reintegration of burn survivors. Survivors who are young, married, employed, and higher functioning at the time of admission to rehabilitation demonstrate the best outcomes. This research will help assess the rehabilitation potential of burn survivors and inform resource allocation.

Risk factors for the development of heterotopic ossification in seriously burned adults: A National Institute on Disability, Independent Living and Rehabilitation Research burn model system database analysis

BACKGROUND Heterotopic ossification (HO) is a debilitating complication of burn injury; however, incidence and risk factors are poorly understood. In this study, we use a multicenter database of adults with burn injuries to identify and analyze clinical factors that predict HO formation. METHODS Data from six high-volume burn centers, in the Burn Injury Model System Database, were analyzed. Univariate logistic regression models were used for model selection. Cluster-adjusted multivariate logistic regression was then used to evaluate the relationship between clinical and demographic data and the development of HO. RESULTS Of 2,979 patients in the database with information on HO that addressed risk factors for development of HO, 98 (3.5%) developed HO. Of these 98 patients, 97 had arm burns, and 96 had arm grafts. When controlling for age and sex in a multivariate model, patients with greater than 30% total body surface area burn had 11.5 times higher odds of developing HO (p < 0.001), and those with arm burns that required skin grafting had 96.4 times higher odds of developing HO (p = 0.04). For each additional time a patient went to the operating room, odds of HO increased by 30% (odds ratio, 1.32; p < 0.001), and each additional ventilator day increased odds by 3.5% (odds ratio, 1.035; p < 0.001). Joint contracture, inhalation injury, and bone exposure did not significantly increase odds of HO. CONCLUSION Risk factors for HO development include greater than 30% total body surface area burn, arm burns, arm grafts, ventilator days, and number of trips to the operating room. Future studies can use these results to identify highest-risk patients to guide deployment of prophylactic and experimental treatments. LEVEL OF EVIDENCE Prognostic study, level III.Purpose Heterotopic ossification (HO) is a debilitating complication of burn injury; however, incidence and risk factors are poorly understood. In this study we utilize a multicenter database of adults with burn injuries to identify and analyze clinical factors that predict HO formation.
