Responsiveness of the patient-specific Canadian occupational performance measure and a fixed-items activity limitations measure in patients with dupuytren disease

BACKGROUND

Patients with Dupuytren disease experience various activity limitations. Treatment aims to reduce finger joint contractures to improve hand function and activity performance. For assessing improvement different patient-centered measures have been used. The Canadian Occupational Performance Measure (COPM) was developed as an interview-based outcome measure to detect changes over time in patients' perception of their performance and satisfaction in self-identified activity issues. The 11-item disabilities of the arm, shoulder and hand (QuickDASH) scale consists of fixed items that ask patients to rate the difficulty in performing specific daily activities. Few studies have compared the responsiveness of these two types of patient-reported measures in Dupuytren disease.

PATIENTS AND METHODS

We included 30 patients with Dupuytren disease enrolled in a prospective cohort study of collagenase injection. We used the COPM (score range 1-10), the QuickDASH (score range 0-100) and measurement of finger joint contracture before and 5 weeks after treatment.

RESULTS

Using the COPM the patients identified 107 activity problems (55 in self-care, 19 in productivity and 33 in leisure). The two most common activity problems were to wash self (21 patients) and to don gloves (19 patients). A clinically important improvement with 3 points or greater from baseline to 5 weeks was seen for performance in 77 activities (72%). The median COPM performance score improved from 4.4 at baseline to 9.0 at 5 weeks and the median QuickDASH score improved from 13.6 to 2.5. Responsiveness (Cohen's d) for the COPM performance was 2.6 (95% CI 1.9-3.3) and for the QuickDASH 0.6 (95% CI 0.1-1.1).

CONCLUSION

The COPM had about 6-fold larger responsiveness than the QuickDASH, which supports use of an individualized measure when assessing treatment effects in Dupuytren disease.

Mental Fatigue, Activities of Daily Living, Sick Leave and Functional Status among Patients with Long COVID: A Cross-Sectional Study

Studies suggest that persistent symptoms after COVID-19 (long COVID) influence functioning and activities of daily living (ADL). However, it is still uncertain how and to what extent. This study aimed to describe patient-reported mental fatigue, ADL problems, ADL ability, sick leave and functional status among patients with long COVID. In this cross-sectional study, 448 patients, ≥18 years old and referred to occupational therapy at a Danish Post-COVID-19 Clinic, were included. Mental fatigue was measured by the Mental Fatigue Scale, ADL problems and ability were measured by the Canadian Occupational Performance Measure, sick leave was self-reported and functional status was evaluated by the Post-COVID-19 Functional Status Scale. Mean age was 46.8 years, 73% of the patients were female, and 75% suffered from moderate to severe mental fatigue. The majority reported difficulties performing productive and leisure activities. The median performance and satisfaction scores were 4.8 and 3, respectively. In total, 56% of the patients were on sick leave, and 94% were referred to rehabilitation. A decrease in functional status was found between pre-COVID-19 and assessment. Conclusively, the patients were highly affected in their everyday life and had distinct rehabilitation needs. Future research is needed to address causalities and rehabilitation for this patient group.

Systematic review of measurement properties of the Canadian Occupational Performance Measure in geriatric rehabilitation

PURPOSE

The Canadian Occupational Performance Measure (COPM) is used to inventory problems experienced by the patient to set goals and evaluate treatment. We aimed to make a systematic overview of measurement properties for people in geriatric rehabilitation.

METHODS

Seven electronic databases were searched for psychometric studies investigating content validity, construct validity, responsiveness, or reliability of the COPM in geriatric rehabilitation populations aged ≥ 60 years. Two reviewers independently abstracted data and assessed methodological quality from included studies.

RESULTS

Of 292 identified articles, 13 studies were included. The COPM showed good test-retest reliability (two studies), moderate inter-rater reliability (one study), and good content validity (one study with some risk of bias). Four studies with minimal risk of bias showed good construct validity as their hypotheses were confirmed. Responsiveness was moderate in three studies with adequate methodological quality.

CONCLUSION

All measurement properties have been studied in geriatric rehabilitation populations, and indicate that the COPM gives relevant information for geriatric rehabilitation, and scores can be assessed reliably and are responsive to change. Although there were many studies on construct validity, authors had different opinions on what exactly COPM-scores tell us, as they used a variety of comparator instruments and different hypotheses. Consensus on exact interpretation of the scores is needed.
