Mapping information regarding the work-related disability of depression and long-term musculoskeletal pain to the International Classification of Functioning, Disability and Health and ICF Core Sets.

Introduction: The International Classification of Functioning, Disability and Health is the WHO coding scheme for functioning-related data. Clear and unambiguous information regarding patients' work-related disabilities is important not only for the assessment of entitlement to paid sickness benefits but also for planning rehabilitation and return to work. The objective was to validate the content of ICF and ICF Core Sets for information on work-related disability in sick leave due to depression and long-term musculoskeletal pain. Specific aims: To describe to what extent (1) such data could be linked to ICF and (2) the result of the ICF linking in terms of ICF categories was represented in relevant ICF Core Sets. Methods: An ICF-linking study following the ICF-linking rules. A random sample of sick leave certificates issued in primary care for either depression (n = 25) or long-term musculoskeletal pain (n = 34) was collected from a community with 55,000 inhabitants in Stockholm County, Sweden. Results: The results of the ICF linking consisted of codings for (1) ICF categories and (2) other health information not possible to link to ICF. The ICF categories were compared to ICF Core Sets for coverage. The majority of the meaning units, 83% for depression and 75% for long-term musculoskeletal pain, were linked to ICF categories. The Comprehensive ICF Core Set for depression covered 14/16 (88%) of the ICF categories derived from the ICF linking. The corresponding figures were lower for both the Brief ICF Core Set for depression 7/16 (44%) and ICF Core Set for disability evaluation in social security 12/20 (60%). Conclusion: The results indicates that ICF is a feasible code scheme for categorising information on work-related disability in sick leave certificates for depression and long-term musculoskeletal pain. As expected, the Comprehensive ICF Core Set for depression covered the ICF categories derived from the certificates for depression to a high degree. However, the results indicate that (1) sleep- and memory functions should be added to the Brief ICF Core Set for depression, and (2) energy-, attention- and sleep functions should be added to the ICF Core Set for disability evaluation in social security when used in this context.

Monitoring independence in daily life activities after trauma in humanitarian settings: Item reduction and assessment of content validity of the Activity Independence Measure-Trauma (AIM-T).

A standardized set of measures to assess functioning after trauma in humanitarian settings has been called for. The Activity Independence Measure for Trauma (AIM-T) is a clinician-rated measure of independence in 20 daily activities among patients after trauma. Designed in Afghanistan, it has since been used in other contexts. Before recommending the AIM-T for wider use, its measurement properties required confirmation. This study aims at item reduction followed by content validity assessment of the AIM-T. Using a two-step revision process, first, routinely collected data from 635 patients at five facilities managing patients after trauma in Haiti, Burundi, Yemen, and Iraq were used for item reduction. This was performed by analyzing inter-item redundancy and distribution of the first version of the AIM-T (AIM-T1) item scores, resulting in a shortened version (AIM-T2). Second, content validity of the AIM-T2 was assessed by item content validity indices (I-CVI, 0-1) based on structured interviews with 23 health care professionals and 60 patients in Haiti, Burundi, and Iraq. Through the analyses, nine pairs of redundant items (r≥0.90) were identified in the AIM-T1, leading to the removal of nine items, and resulting in AIM-T2. All remaining items were judged highly relevant, appropriate, clear, feasible and representative by most of participants (I-CVI>0.5). Ten items with I-CVI 0.5-0.85 were revised to improve their cultural relevance or appropriateness and one item was added, resulting in the AIM-T3. In conclusion, the proposed 12-item AIM-T3 is overall relevant, clear, and representative of independence in daily activity after trauma and it includes items appropriate and feasible to be observed by clinicians across different humanitarian settings. While some additional measurement properties remain to be evaluated, the present version already has the potential to serve as a routine measure to assess patients after trauma in humanitarian settings.

Exploring the Perth Hamstring Assessment Tool and Lower Extremity Functional Scale in a Proximal Hamstring Avulsion Cohort: A Cross-sectional Study.

BACKGROUND: The goal of treatment for a proximal hamstring avulsion (PHA) is an objectively restored muscle and a subjectively satisfied, pain-free patient at follow-up. Different self-reported and performance-based outcome measures have been used to evaluate recovery, but their validity is poorly investigated. PURPOSE: To investigate (1) the correlation between the commonly used self-reported outcome measurements, the Perth Hamstring Assessment Tool (PHAT) and the Lower Extremity Functional Scale (LEFS); (2) to what extent these scores can be explained by physical dysfunction as measured by performance-based tests; (3) whether performance-based tests can discriminate between the injured and uninjured extremity; and (4) which activity limitations are perceived by patients several years after the injury. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 3. METHODS: We included a consecutive series of patients treated for or diagnosed with PHA in our department between 2007 and 2016 having at least 2 tendons avulsed from the ischial tuberosity. Participants attended 2 study visits, answered questionnaires (PHAT, LEFS, and Patient-Specific Functional Scale [PSFS]), and performed physical performance-based tests (single-leg hop tests, single-step down test, and isometric and isokinetic strength tests). RESULTS: A total of 50 patients were included (26 men [52%], 24 women [48%]; mean age, 50.9 years [SD, 9.8 years]). The mean follow-up time was 5.5 years (SD, 2.7 years), and 74% had been surgically treated. The correlation between PHAT and LEFS was strong (r = 0.832) and statistically significant (P < .001). Seven of the performance-based tests exhibited a statistically significant but weak correlation with LEFS (0.340-0.488) and 3 of the tests to PHAT (-0.304 to 0.406). However, only peak torque could significantly discriminate between the extremities. The activity limitation most commonly mentioned in PSFS was running (16 patients [32%]). CONCLUSION: Although PHAT and LEFS correlated strongly, the correlations between functional tests and the patient-reported outcome scores were weak, and most functional tests failed to discriminate between the injured and uninjured lower extremity in patients with PHA 5 years after injury. In general, patients alleged few activity limitations, but running difficulty was a common sequela after PHA.

Mapping a measure of physical ability for persons with long-term musculoskeletal pain to the ICF and ICF Core Sets.

BACKGROUND: Test Instrument for Profile of Physical Ability (TIPPA) is used in the Swedish sickness certification process for patients with long-term musculoskeletal pain. The aim was to explore the content of TIPPA in the context of work-ability assessments. METHODS: The full protocol of TIPPA was linked to the in relation to the International Classification of Functioning, Disability and Health (ICF) and evaluated in relation to the ICF Core Sets for Chronic Widespread Pain (CWP). RESULTS: Twenty-two unique meaningful concepts were identified in TIPPA. Eighteen of those could be linked to ICF, yielding 27 third-level ICF-categories. Ten of these categories fitted the domains of 'body function', 16 were 'activity and participation', while one was related to 'environmental factors'. Perspective and aim varied between the parts of the test. When assessed against Brief ICF Core Set for CWP, TIPPA covered three of nine 'body function' categories and 2 out of 10 'activity and participation' categories. The coverage of the subgroup 'activity' was two out of five. TIPPA did not cover three categories, i.e. 'd175 solving problems', 'd230 carrying out daily routine' and 'd240 handling stress and other psychological demands', in the subgroup of 'activity'. CONCLUSIONS: TIPPA could be a useful measure for the assessment of physical ability. However, additional condition-specific items/measures are required to obtain full coverage of core aspects of functioning and disability in a comprehensive work-ability assessment for patients with long-term musculoskeletal pain.

Cost-effectiveness of the HiBalance training program for elderly with Parkinson's disease: analysis of data from a randomized controlled trial.

OBJECTIVE:: To determine the cost-effectiveness of the HiBalance training program for managing Parkinson's disease (PD)-related balance and gait disorders. DESIGN:: Cost comparison design following the randomized controlled trial comparing a novel balance training intervention with care as usual. SUBJECTS:: A total of 100 participants with mild-moderate PD were randomized to either the intervention ( n = 51) or the control group ( n = 49). INTERVENTION:: A 10-week (three times per week), group-based, progressive balance training program, led by two physical therapists. MAIN OUTCOMES:: All program costs were collected for both groups. Cost-utility was evaluated using quality-adjusted life years (QALYs) and cost-effectiveness measures were the Mini Balance Evaluation Systems Test (Mini-BESTest; assessing balance performance) and gait velocity. Incremental cost-effectiveness ratios were calculated and a probabilistic sensitivity analysis was conducted. RESULTS:: The between-group difference in QALYs was 0.043 (95% confidence interval (CI): 0.011-0.075), favoring the intervention group. Between-group differences in balance performance and gait velocity were 2.16 points (95% CI: 1.19-3.13) and 8.2 cm/second (95% CI: 2.9-13.6), respectively, favoring the intervention group. The mean cost per participant in the intervention group was 16,222 SEK (€1649) compared to 2696 SEK (€274) for controls. The estimated incremental cost-effectiveness ratios were 314,558 SEK (€31,969) for an additional QALY, 6262 SEK (€631) for one point improvement in balance performance, and 1650 SEK (€166) for 1 cm/second increase in gait velocity. Sensitivity analyses indicated a high probability (85%) of program success. CONCLUSION:: In terms of QALYs, the HiBalance program demonstrated a high probability of cost-effectiveness in the short-term perspective when considering the willingness-to-pay thresholds used in Europe.

Cost-effectiveness of a one-year coaching program for healthy physical activity in early rheumatoid arthritis.

PURPOSE: To describe cost-effectiveness of the Physical Activity in Rheumatoid Arthritis (PARA) study intervention. METHOD: Costs were collected and estimated retrospectively. Cost-effectiveness was calculated based on the intervention cost per patient with respect to change in health status (EuroQol global visual analog scale--EQ-VAS and EuroQol--EQ-5D) and activity limitation (Health assessment questionnaire - HAQ) using cost-effectiveness- and cost-minimization analyses. RESULTS: Total cost of the one-year intervention program was estimated to be €67 317 or €716 per participant. Estimated difference in total societal cost between the intervention (IG) and control (CG) was €580 per participant. Incremental cost-effectiveness ratio (ICER) for one point (1/100) of improvement in EQ-VAS was estimated to be €116. By offering the intervention to more affected participants in the IG compared to less affected participants, 15.5 extra points of improvement in EQ-VAS and 0.13 points of improvement on HAQ were gained at the same cost. "Ordinary physiotherapy" was most cost-effective with regard to EQ-5D. CONCLUSIONS: The intervention resulted in improved effect in health status for the IG with a cost of €116 per extra point in VAS. The intervention was cost-effective if targeted towards a subgroup of more affected patients when evaluating the effect using VAS and HAQ. IMPLICATIONS FOR REHABILITATION: The physical activity coaching intervention resulted in an improved effect on VAS for the intervention group, to a higher cost. In order to maximize cost-effectiveness, this type of physical activity coaching intervention should be targeted towards patients largely affected by their RA. The intervention is cost-effective from the patients' point of view, but not from that of the general population.
