Delivery of a quality improvement program in team-based rehabilitation for patients with rheumatic and musculoskeletal diseases: a mixed methods study

PURPOSE

To investigate how a quality improvement program (BRIDGE), designed to promote coordination and continuity in rehabilitation services, was delivered and perceived by providers in routine practice for patients with rheumatic and musculoskeletal diseases.

METHODS

A convergent mixed methods approach was nested within a stepped-wedge, randomized controlled trial. The intervention program was developed to bridge gaps between secondary and primary healthcare, comprising the following elements: motivational interviewing; patient-specific goal setting; written rehabilitation-plans; personalized feedback on progress; and tailored follow-up. Data from health professionals who delivered the program were collected and analyzed separately, using two questionnaires and three focus groups. Results were integrated during the overall interpretation and discussion.

RESULTS

The program delivery depended on the providers' skills and competence, as well as on contextual factors in their teams and institutions. Suggested possibilities for improvements included follow-up with sufficient support from next of kin and external services, and the practicing of action and coping plans, standardized outcome measures, and feedback on progress.

CONCLUSIONS

Leaders and clinicians should discuss efforts to ensure confident and qualified rehabilitation delivery at the levels of individual providers, teams, and institutions, and pay equal attention to each component in the process from admission to follow-up.

Finalisation and validation of the rheumatoid arthritis impact of disease score, a patient-derived composite measure of impact of rheumatoid arthritis: a EULAR initiative

OBJECTIVE

A patient-derived composite measure of the impact of rheumatoid arthritis (RA), the rheumatoid arthritis impact of disease (RAID) score, takes into account pain, functional capacity, fatigue, physical and emotional wellbeing, quality of sleep and coping. The objectives were to finalise the RAID and examine its psychometric properties.

METHODS

An international multicentre cross-sectional and longitudinal study of consecutive RA patients from 12 European countries was conducted to examine the psychometric properties of the different combinations of instruments that might be included within the RAID combinations scale (numeric rating scales (NRS) or various questionnaires). Construct validity was assessed cross-sectionally by Spearman correlation, reliability by intraclass correlation coefficient (ICC) in 50 stable patients, and sensitivity to change by standardised response means (SRM) in 88 patients whose treatment was intensified.

RESULTS

570 patients (79% women, mean ± SD age 56 ± 13 years, disease duration 12.5 ± 10.3 years, disease activity score (DAS28) 4.1 ± 1.6) participated in the validation study. NRS questions performed as well as longer combinations of questionnaires: the final RAID score is composed of seven NRS questions. The final RAID correlated strongly with patient global (R=0.76) and significantly also with other outcomes (DAS28 R=0.69, short form 36 physical -0.59 and mental -0.55, p<0.0001 for all). Reliability was high (ICC 0.90; 95% CI 0.84 to 0.94) and sensitivity to change was good (SRM 0.98 (0.96 to 1.00) compared with DAS28 SRM 1.06 (1.01 to 1.11)).

CONCLUSION

The RAID score is a patient-derived composite score assessing the seven most important domains of impact of RA. This score is now validated; sensitivity to change should be further examined in larger studies.

Elaboration of the preliminary Rheumatoid Arthritis Impact of Disease (RAID) score: a EULAR initiative

BACKGROUND

Current response criteria in rheumatoid arthritis (RA) usually assess only three patient-reported outcomes (PROs): pain, functional disability and patient global assessment. Other important PROs such as fatigue are not included.

OBJECTIVE

To elaborate a patient-derived composite response index for use in clinical trials in RA, the RA Impact of Disease (RAID) score.

METHODS

Ten patients identified 17 domains or areas of health relevant for inclusion in the score, then 96 patients (10 per country in 10 European countries) ranked these domains in order of decreasing importance. The seven most important domains were selected. Instruments were chosen for each domain after extensive literature research of psychometric properties and expert opinion. The relative weight of each of the domains was obtained from 505 patients who were asked to "distribute 100 points" among the seven domains. The average ranks of importance of these domains were then computed.

RESULTS

The RAID score includes seven domains with the following relative weights: pain (21%), functional disability (16%), fatigue (15%), emotional well-being (12%), sleep (12%), coping (12%) and physical well-being (12%). Weights were similar across countries and across patient and disease characteristics. Proposed instruments include the Health Assessment Questionnaire and numerical ratings scales.

CONCLUSION

The preliminary RAID score is a patient-derived weighted score to assess the impact of RA. An ongoing study will allow the final choice of questionnaires and assessment of validity. This score can be used in clinical trials as a new composite index that captures information relevant to patients.

Performance of health status measures with a pen based personal digital assistant

BACKGROUND

Increasing use of self reported health status in clinical practice and research, as well as patient appreciation of monitoring fluctuations of health over time, suggest a need for more frequent collection of data. Electronic use of health status measures in the follow up of patients is a possible way to achieve this.

OBJECTIVE

To compare self reported health status measures in a personal digital assistant (PDA) version and a paper/pencil version for test-retest reliability, agreement between scores, and feasibility.

METHODS

30 patients with stable rheumatoid arthritis (mean age 61.6 years, range 49.8 to 70.0; mean disease duration, 16.7 years; 63% female; 67% rheumatoid factor positive; 46.6% on disease modifying antirheumatic drugs) completed self reported health status measures (pain, fatigue, and global health on visual analogue scales (VAS), rheumatoid arthritis disease activity index, modified health assessment questionnaire, SF-36) in a conventional paper based questionnaire version and on a PDA (HP iPAQ, model h5450). Completion was repeated after five to seven days.

RESULTS

Test-retest reliability was similar, as evaluated by the Bland-Altman approach, the coefficient of variation, and intraclass correlation coefficients. The scores showed acceptable agreement, but with a slight tendency to higher scores on VAS with the PDA than the paper/pencil version. No significant differences were seen for measures of feasibility (time to complete, satisfaction score), but 65.5% preferred PDA, 20.7% preferred paper, and 13.8% had no preference.

CONCLUSIONS

The clinimetric performance of paper/pencil versions of self reported health status measures was similar to an electronic version, using an inexpensive PDA.
