Evaluating a complex intervention addressing ability to perform activities of daily living among persons with chronic conditions: study protocol for a randomised controlled trial (ABLE)

Qualitative realist evaluation of an occupational therapy intervention programme (ABLE), addressing ability to perform activities of daily living among persons with chronic conditions

BACKGROUND

Chronic conditions are associated with problems related to performance of activities of daily living (ADL) stressing a need to develop and evaluate intervention programmes addressing such problems. Hence, the ABLE programme was developed, and its feasibility evaluated. Implementing intervention programmes in community-based rehabilitation settings requires understanding of how the programme works in various contexts. Applying a realist evaluation approach, the aim of this study was to identify and evaluate interactions between contexts, mechanisms, and outcomes in the ABLE 2.0, to confirm, refine, or reject aspects of the initial programme theory.

METHODS

Realist evaluation using qualitative data collected in the ABLE 2.0 randomised controlled trial (n = 78). Based on the ABLE 2.0 initial programme theory, qualitative realist interviews were conducted among receivers (n = 8) and deliverers (n = 3) of the ABLE 2.0 in a Danish municipality. Transcripts were coded, and context-mechanism-outcome configurations were extracted and grouped into contiguous themes. Results were then held up against the initial programme theory.

RESULTS

Four contiguous themes were identified including a total of n = 28 context-mechanism-outcome configurations: building a foundation for the entire intervention; establishing the focus for further intervention; identifying and implementing relevant compensatory solutions; and re-evaluating ADL ability to finalise intervention. Overall, the ABLE 2.0 initial programme theory was confirmed. The evaluation added information on core facilitating mechanisms including active involvement of the client in the problem-solving process, a collaborative working relationship, mutual confidence, and a consultative occupation-based process using compensatory solutions. Several contextual factors were required to activate the desired mechanisms in terms of supportive management, referral procedures encouraging the problem-solving process, delivery in the client's home, skilled occupational therapists, and clients feeling ready for making changes.

CONCLUSIONS

The ABLE 2.0 represents a coherent problem-solving occupational therapy process, applicable across sex, age, and diagnoses with the potential to enhance ADL ability among persons with chronic conditions, when delivered as part of community-based rehabilitation services. Knowledge about the interactions between contextual factors, mechanisms, and outcomes in the ABLE 2.0 is central in case of future implementation of the programme in community-based rehabilitation settings.

Changes in self-perceived performance and satisfaction with performance of daily activities following interdisciplinary rehabilitation in people with late effects of polio

BACKGROUND

People with late effects of polio (LEoP) may need rehabilitation to manage everyday life but knowledge of the benefits of interdisciplinary rehabilitation is limited.

OBJECTIVE

To evaluate changes in performance and satisfaction with performance of activities among people with LEoP following interdisciplinary rehabilitation.

METHODS

A pre-post retrospective study based on data on 102 participants with LEoP from a rehabilitation clinic. Changes in performance and satisfaction with performance of daily activities before and after interdisciplinary rehabilitation were assessed with the Canadian Occupational Performance Measure (COPM).

RESULTS

There were statistically significant increases in the mean performance and mean satisfaction with performance COPM scores from admission to discharge. Twenty-three percent and 19% of the participants, respectively, had improved their performance and satisfaction with performance, 25% and 26% of the participants had no changes, and 19% and 22% of the participants, respectively, rated their performance and satisfaction lower at discharge compared to admission.

CONCLUSION

Interdisciplinary rehabilitation can enhance self-rated performance and satisfaction with performance of daily activities among people with LEoP. Future studies of rehabilitation for people with LEoP should use a prospective design and capture the participants' process of change related to their rehabilitation period.

Perspectives on content and delivery of the ABLE 1.0 intervention programme

BACKGROUND

The occupational therapy intervention programme ABLE 1.0 was designed to enhance the ability to perform activities of daily living in persons living with chronic conditions. There is a need to determine if content and delivery of the ABLE 1.0 are acceptable among occupational therapists (OTs) and clients after having delivered or received the programme, respectively.

OBJECTIVES

The paper reports on evaluation of content and delivery of the ABLE 1.0 among OTs and clients. This, in terms of acceptability of intervention in principle, and perceived value, benefits, harms, or unintended consequences of the intervention.

MATERIAL AND METHODS

Qualitative semi-structured interviews were conducted with OTs having delivered and clients having received ABLE 1.0 in a Danish municipality. Content analysis was performed.

FINDINGS

Two OTs and three clients participated. Analyses revealed six categories related to content and delivery; 'Overall perception of the programme'; 'Potential for implementation'; 'Evaluation, goal setting and clarification of reasons for ADL task performance problems'; 'Intervention: compensatory solutions'; 'Format and duration' and 'Preconditions for delivery'.

CONCLUSIONS AND SIGNIFICANCE

The findings provided valuable information used for further development of the ABLE programme.

Effectiveness of an individualised occupational therapy intervention programme (ABLE) using adaptational strategies on activities of daily living among persons with chronic conditions: A randomised controlled trial (RCT)

OBJECTIVE

Compare the effectiveness of a problem-solving, individualised, home-based occupational therapy intervention (ABLE 2.0), to usual occupational therapy, on activities of daily living (ADL) ability in persons with chronic conditions.

DESIGN

A single-centre, double-blinded, randomised controlled trial with 10- and 26-week follow-up.

SETTING

A Danish municipality.

SUBJECTS

Persons with chronic conditions experiencing problems performing ADL tasks (n = 80).

INTERVENTIONS

ABLE 2.0 was compared with usual occupational therapy.

MAIN MEASURES

Coprimary outcomes were self-reported ADL ability (ADL-Interview Performance) and observed ADL motor ability (Assessment of Motor and Process Skills) at Week 10. Secondary outcomes were self-reported ADL ability (ADL-Interview Performance) and observed ADL motor ability (Assessment of Motor and Process Skills) at Week 26, and perceived satisfaction with ADL ability (ADL-Interview Satisfaction) and observed ADL process ability (Assessment of Motor and Process Skills) at Weeks 10 and 26.

RESULTS

In total, 78 persons were randomly assigned: 40 to usual occupational therapy and 38 to ABLE 2.0. No statistically significant nor clinically relevant difference between group mean changes in primary outcomes was identified from baseline to Week 10 (ADL-Interview Performance [-0.16; 95% CI: -0.38 to 0.06] and Assessment of Motor and Process Skills ADL motor ability [-0.1; 95% CI: -0.3 to 0.1]). At Week 26, a statistically significant and clinically relevant difference was found in Assessment of Motor and Process Skills ADL motor ability (LS mean change: -0.3; 95% CI: -0.5 to -0.1) between groups.

CONCLUSION

ABLE 2.0 was effective in improving observed ADL motor ability at 26 weeks.
