Interpreting Life Impact Burn Recovery Evaluation Profile Scores for Use by Clinicians, Burn Survivors, and Researchers

Moderation Effects of Daily Behavior on Associations Between Symptoms and Social Participation Outcomes After Burn Injury: A 6-Month Digital Phenotyping Study

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.

Evaluation of patient-reported outcome measures in burn-specific tools: A systematic review

INTRODUCTION

Patient-reported outcome measures (PROMs) are now well-established tools to evaluate the quality of patient-centred care. Due to the multi-faceted and multi-disciplinary nature of the practice of burn care, as well as the range of significant potential sequelae, PROM's should form a fundamental component of burn quality improvement programs. We aim to 1. Explore biological, psychological, and social considerations that are currently listed in burn-specific PROM tools, as well as their efficacy, 2. Evaluate biological, psychological, and social factors that are considered in new burn-specific PROM tools or those under development, and 3. Identify any opportunities with respect to burn-specific PROM tools, in order to inform future investigation in this area.

METHODS

A search was performed of MEDLINE (Ovid), EMBASE, CINAHL, and the Cochrane Library databases. Two independent reviewers screened article titles/abstracts and then the full texts using Covidence. All studies were graded independently according to the Quality Rating Scheme for Studies and Other Evidences.

RESULTS

The initial search yielded 552 references. Based on ab initio inclusion and exclusion criteria, 133 full-text studies were assessed for eligibility, and 21 articles were ultimately included in the systematic review. Due to study heterogeneity, a qualitative synthesis was conducted. Existing burn-specific PROMs covered a range of biological, psychological, and social factors affecting adult and paediatric patients with burn injury, but several studies required additional PROMs for a thorough evaluation. Burn-specific PROM tools under development are poised to fill this deficit.

CONCLUSION

Major burn injuries are a unique form of trauma, requiring coordinated management that considers numerous factors not relevant to other patient populations. Further research is necessary to validate existing burn-specific PROM tools and to develop more comprehensive burn-specific PROM measures that more comprehensively incorporate the bio-psycho-social model of health.

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.

Trajectory Curves for Purposes of Benchmarking and Predicting Clinical Outcomes: A Scoping Review

Trajectory curves are valuable tools to benchmark patient health status and predict future outcomes. A longitudinal study is underway to examine social participation after burn injury using the Life Impact Burn Recovery Evaluation (LIBRE) Profile with the goal of developing trajectory curves for specific domains that focus on social reintegration. We conducted a scoping review to inform and understand trajectory curves applied in clinical settings to compare outcomes for an individual to a matched cohort of comparable patients or predicted expected outcomes over time. This scoping review utilized a PubMed search from January 2014 to August 2019 for the following terms: "trajectory curves" or "trajectory models" and "clinic" or "clinical." Only articles that specifically referenced longitudinal and clinical research designs were included in the scoping review. Articles were assessed using standard scoping review methods and categorized based on clinical application of trajectory curves for either benchmarking or prediction. The initial literature review identified 141 manuscripts and 34 met initial inclusion criteria. The reviewed articles support the clinical use of trajectory curves. Findings provide insight into several key determinants involved with the successful development and implementation of trajectory curves in clinical settings. These findings will inform efforts to use the LIBRE Profile to model social participation recovery and assist in developing effective strategies using trajectory curves to promote social reintegration after burn injury.

Development and initial validation of ability levels to interpret pediatric spinal cord injury activity measure and pediatric measure of participation scores

PURPOSE

To develop ability levels and descriptions to interpret Pediatric Spinal Cord Injury Activity Measure (PEDI-SCI AM) and Pediatric Measure of Participation (PMoP) scores.

METHODS

Mixed-methods approach to 1.) create item maps using PEDI-SCI AM and PMoP calibration data; 2.) employ bookmarking methods and an iterative consensus process including semi-structured interviews, focus groups and surveys to establish PEDI-SCI AM and PMoP level score cut-points and descriptions; 3.) use calibration sample data to examine mean score differences across levels [analyses of variance (ANOVAs)] and assess the sample distribution (%) across levels; 4.) repeat in a separate validation sample; 5.) develop level descriptions. Throughout the mixed methods approach, the sample participants include children with spinal cord injury (SCI), parents of children with SCI, and professionals who work with children with SCI.

RESULTS

Four or five ability levels were identified for each PEDI-SCI AM and PMoP domain along with descriptions for each level. ANOVA results revealed significant overall differences for level mean scores and pairwise comparisons (p < 0.05). Consensus (>80%) was achieved for all PEDI-SCI AM and some PMoP level descriptions.

CONCLUSION

PEDI-SCI AM and PMoP score cut-points identify different levels of activity and participation among children with SCI. These levels and descriptions provide clinical relevance for PEDI-SCI and PMoP numeric scores.
