Objective Burn Scar Assessment in Clinical Practice Using the Cutometer©: Introduction and Validation of a Standardized Measurement Protocol.

An objective burn scar assessment is essential to informed therapeutic decision-making and to monitor scar development over time. However, widely employed scar rating scales show poor inter-rater reliability. For this study we developed a standardized measurement protocol for the Cutometer© applicable for objective burn scar assessment in everyday clinical practice. We developed a measurement protocol for the Cutometer© MPA 580 including a scar site relocation technique based on anatomical landmarks. The protocol emerged through several steps: Identifying key factors for valid and reliable measurements, preliminary testing, specification of technical details, refining the protocol and final testing. Consecutively, the protocol was validated for inter-rater reliability by assessing 34 burn scars in 17 patients by four clinicians and computing an Intra-class Correlation Coefficient (ICC). Parameter R0, representing scar pliability, was identified as the best suited output parameter yielding excellent inter-rater reliability for average measures (ICC 0.92 [95% CI 0.86; 0.96]) and acceptable reliability for single measures (ICC: 0.74 [0.61; 0.84]). The pressure applied on the measuring probe was identified as an influential confounding factor for reliable measurements. Rater gender did not influence reliability of measurements. The introduced standardized measurement protocol for the Cutometer© MPA 580 enables an objective and reliable burn scar assessment for clinical as well as research purposes.

Evaluation of an International Classification of Functioning, Disability and Health-based rehabilitation for thermal burn injuries: a prospective non-randomized design.

BACKGROUND: Severe burn injuries result in relevant restrictions of physical capacity as well as psychological and social integrity and require a specialized rehabilitation. There is a common agreement, among national as well as international burn associations, that burn rehabilitation is a complex, dynamic process which needs an interdisciplinary and specialized treatment team. There is wide agreement that more research is needed in this field. METHODS/DESIGN: The aim of the study is to examine the effectiveness and efficiency of our new ICF (International Classification of Functioning, Disability and Health)-based rehabilitation for thermal injuries. Because of ethical reasons, we have chosen a prospective non-randomized design, which takes place at two different rehabilitation centers. At center A, a newly developed ICF-based rehabilitation program was established; at rehabilitation center B, a well-established rehabilitation program has existed for 20 years and is used as reference. The primary research question addresses the "Pre-post comparison of the physical and psychological outcome measurements," secondary question I looks at the "Examination of the non-inferiority of the new treatment concept with the established concept," and secondary question II is the "Analysis of the rehabilitation process based on the rehabilitation cycle." Only patients of the two burn rehabilitation centers who are insured by workers' compensation will be asked to participate in this study to avoid outcome bias by insurance status. A physical examination (physical working capacity testing, grip strength, range of motion, and scar evaluation by Cutometer and Vancouver Scar Scale) and a standardized questionnaire battery (Burn Specific Health Scale-Brief , Short Form 36, Impact of Event Scale-Revised, the German version of the Symptom Checklist, the Freiburg Social Support Questionnaire, Patient/Client Satisfaction Questionnaire, Disabilities of the Arm, Shoulder and Hand, and Lower Extremity Functional Scale ) measure physical and psychological conditions. Data will be taken on admission, during stay, and on discharge of the rehabilitation program and at follow-up 3 and 12 months after discharge. A minimum of 162 participants will be enrolled in this clinical longitudinal, prospective, observational study. DISCUSSION: The proof of the effectiveness of the ICF-based rehabilitation program for thermal injuries will give evidence in a comprehensive way for the first time in this field. As result, a standardized rehabilitation concept will be introduced, which can be provided to other rehabilitation institutions treating thermal injuries.

Validation of the Ludwigshafen German Version of the Burn Specific Health Scale-Brief.

The Burn Specific Health Scale-Brief (BSHS-B) is one of the most commonly used instruments to measure quality of life after burns. Our aim was to establish and to provide a German version of the BSHS-B for all German-speaking burn facilities. Translation and cross-cultural adaptation of the original English version into the German language was conducted. In a pilot study, 20 burn patients qualitatively validated the translated version concerning comprehensibility and content validity. The final version was then quantitatively validated by 364 patients who were treated in our burn center between 2011 and 2015. Internal consistency and test-retest reliability were assessed. Criterion validity was determined by correlating the subscales with relevant instruments (Short-Form Health Survey 36, Hospital Anxiety and Depression Scale, and Disabilities of the Arm, Shoulder and Hand Outcome Measure). The structure of the German version was investigated by principal component analysis. Confirmatory factor analysis was used to compare the structure with the original 9-factor structure and the second-order 3-factor structure. Qualitative testing revealed adequate comprehension and content validity. Cronbach's alphas ranged from α = 0.80 to α = 0.92. The test-retest reliability ranged from r = 0.72 to r = 0.97. The subscales correlated significantly with the measures of criterion validity (r = 0.30 to r = -0.77). The principal component analysis results showed a satisfactory overlap with the original data structure, except for the Affect and Sexuality domains, which were merged into 1 factor. The confirmatory factor analyses revealed the best model fit for the second-order 3-factor structure, excluding the Work domain. The Ludwigshafen German version of the BSHS-B shows good psychometric properties. It is well suited for clinical use, further research, and international comparison.

Efficacy of a burn-specific cognitive-behavioral group training.

OBJECTIVE: The aim of the present study was to evaluate the efficacy of a newly developed cognitive-behavioral group training, specifically designed for burn patients. METHOD: In a multicenter-study data pre- and post treatment and at 6-month follow-up were obtained from participants of the group program (Intervention group, IG; n=86) and a control group who received treatment as usual (TAU; n=128). Outcome variables of psychological distress, resources and health-related quality of life of both groups were compared using linear mixed models. RESULTS: Up to 6 months after group treatment, the IG reported a substantial decline of general symptom severity as well as posttraumatic stress, whereas the TAU group showed no significant change over time. Optimism increased in the IG after group treatment, but not in the TAU group. Regarding overall quality of life both groups showed a gradual improvement over the three assessment points. CONCLUSION: The newly developed burn-specific cognitive-behavioral group intervention had positive effects on psychological well-being and resources of burn participants. As a consequence, the group intervention has been implemented as inherent part of the regular burn treatment in two rehabilitation centers in Germany.

Quality of life and predictors of long-term outcome after severe burn injury.

The aim of this study was to identify the long-term quality of life after severe burn injury. In a prospective longitudinal design, N = 265 burn patients were examined 6, 12, 24, and 36 months after burn injury. A multilevel approach was used to measure stability and change in self-reported health status. Besides injury-related variables, self-report instruments included measures of quality of life, psychological distress, personality, and specific burn outcome measures. Fitting of unconditional growth models indicated that there was significant intra- and inter-individual variation in self-reported physical and mental health short form-12. Over the course of 3 years, participants reported on average a slight improvement of physical quality of life. Physical health was mainly predicted by mobility and level of burn severity. Variance in mental health status was mainly predicted by gender, mobility, neuroticism, level of depression and posttraumatic stress disorder (PTSD)-related avoidance. Thus mobility (i.e., simple abilities) seems a crucial variable for overall quality of life. An early identification and treatment of patients with high levels of depression and PTSD-related avoidance may contribute to better mental health.

Emotional distress and psychosocial resources in patients recovering from severe burn injury.

Emotional distress as well as psychosocial resources in 55 patients with burn injuries was assessed during acute and follow-up treatment. Results showed significantly greater values of emotional distress among patients when compared with norms of the general population. As well as higher levels of general psychopathology, particularly prevalent were anxiety, depression, and posttraumatic symptoms. However, patients also reported high levels of resources such as general optimism, self-efficacy, and perceived social support. Within the sample, no significant correlation between severity of emotional distress and severity of burn injury was found. By psychological assessments a subgroup of highly distressed patients was identified. These patients were highly emotionally distressed while having objective injury severity comparable with the other patients in the sample. Reactions to burn accidents vary individually. The results demonstrate the importance of routine screenings of psychological symptoms. An early identification of patients at-risk allows for tailored psychotherapeutic interventions and can thus help to improve quality of life and general well-being of burn patients on a long-term basis.
