Community occupational therapy for older patients with dementia and their care givers: cost effectiveness study.

Objective To assess the cost effectiveness of community based occupational therapy compared with usual care in older patients with dementia and their care givers from a societal viewpoint. Design Cost effectiveness study alongside a single blind randomised controlled trial. Setting Memory clinic, day clinic of a geriatrics department, and participants’ homes. Patients 135 patients aged ≥65 with mild to moderate dementia living in the community and their primary care givers. Intervention 10 sessions of occupational therapy over five weeks, including cognitive and behavioural interventions, to train patients in the use of aids to compensate for cognitive decline and care givers in coping behaviours and supervision. Main outcome measures Incremental cost effectiveness ratio expressed as the difference in mean total care costs per successful treatment (that is, a combined patient and care giver outcome measure of clinically relevant improvement on process, performance, and competence scales) at three months after randomisation. Bootstrap methods used to determine confidence intervals for these measures. Results The intervention cost €1183 (£848,

The number needed to treat for successful treatment at three months was 2.8 (2.7 to 2.9). Conclusions Community occupational therapy intervention for patients with dementia and their care givers is successful and cost effective, especially in terms of informal care giving.

Barriers to and facilitators for the use of an evidence‐based occupational therapy guideline for older people with dementia and their carers

BACKGROUND There is insufficient evidence to support use of occupational therapy interventions for patients with Parkinsons disease. We aimed to assess the efficacy of occupational therapy in improving daily activities of patients with Parkinsons disease. METHODS We did a multicentre, assessor-masked, randomised controlled clinical trial in ten hospitals in nine Dutch regional networks of specialised health-care professionals (ParkinsonNet), with assessment at 3 months and 6 months. Patients with Parkinsons disease with self-reported difficulties in daily activities were included, along with their primary caregivers. Patients were randomly assigned (2:1) to the intervention or control group by a computer-generated minimisation algorithm. The intervention consisted of 10 weeks of home-based occupational therapy according to national practice guidelines; control individuals received usual care with no occupational therapy. The primary outcome was self-perceived performance in daily activities at 3 months, assessed with the Canadian Occupational Performance Measure (score 1-10). Data were analysed using linear mixed models for repeated measures (intention-to-treat principle). Assessors monitored safety by asking patients about any unusual health events during the preceding 3 months. This trial is registered with ClinicalTrials.gov, NCT01336127. FINDINGS Between April 14, 2011, and Nov 2, 2012, 191 patients were randomly assigned to the intervention group (n=124) or the control group (n=67). 117 (94%) of 124 patients in the intervention group and 63 (94%) of 67 in the control group had a participating caregiver. At baseline, the median score on the Canadian Occupational Performance Measure was 4·3 (IQR 3·5-5·0) in the intervention group and 4·4 (3·8-5·0) in the control group. At 3 months, these scores were 5·8 (5·0-6·4) and 4·6 (4·6-6·6), respectively. The adjusted mean difference in score between groups at 3 months was in favour of the intervention group (1·2; 95% CI 0·8-1·6; p<0·0001). There were no adverse events associated with the study. INTERPRETATION Home-based, individualised occupational therapy led to an improvement in self-perceived performance in daily activities in patients with Parkinsons disease. Further work should identify which factors related to the patient, environmental context, or therapist might predict which patients are most likely to benefit from occupational therapy.

The impact of occupational therapy in Parkinson’s disease: a randomized controlled feasibility study

Objective: To enhance insight into the process of occupational therapy (OT) and the changes after OT, in an older patient with mild dementia and his primary caregiver. Design and setting: Case study: content analysis of an OT patient record. Intervention: System-based OT at home using a guideline focusing on both patients performance in daily activities and caregivers cognition on patient behaviour and caregiver role and focusing on adaptation of the physical environment. Measures: Triangulation of results of qualitative content analysis and quantitative description using the following measures: Brief Cognitive Rating Scale (BCRS), Assessment of Motor and Process Skills (AMPS), Interview of Deterioration in Daily Activities in Dementia (IDDD), Canadian Occupational Performance Measurement (COPM), Dementia Quality of Life Instrument (DQOL), Sense of Competence Scale (SCQ) and the Mastery Scale. Results: The global categories derived from content analysis were: daily performance and communication. The specific categories were the patient with dementia, his or her caregiver and the occupational therapist. Important themes derived from content analysis were: patients capacity for pleasure, autonomy and appreciation in performing daily activities and caregivers competence. Patients changes reported after OT: more initiative, autonomy and pleasure in performing daily activities, increase of quality of life; caregivers changes reported after OT: improved communication and supervision skills, changed cognition on patient behaviour and caregiver role, improved sense of competence. The quantitative results showed an improved daily performance (e.g. initiative, motor and process skills, need for assistance) and quality of life of the patient and improved sense of competence, quality of life and mastery of the situation of the caregiver after OT intervention. Thus the results of the qualitative content analysis were supported by the quantitative results. Additionally, based on the results of the content analysis an exploratory and system-based model has been developed connecting OT diagnosis and OT treatment at home for patients with dementia and their primary caregivers. Conclusion: This case study provides information on how occupational therapy can improve the daily performance, communication, sense of competence and quality of life of an older patient with dementia and his or her primary caregiver. A combination of education, setting feasible goals, using adaptations in physical environment, training compensatory skills, training supervision skills, and changing dysfunctional cognitions on patient behaviour and caregiver role seemed to be successful. A randomized controlled trial must provide information on the effects of OT at home for older patients with dementia and their primary caregivers.

Economic evaluation of occupational therapy in Parkinson's disease: A randomized controlled trial

For cluster randomized trials with a continuous outcome, the sample size is often calculated as if an analysis of the outcomes at the end of the treatment period (follow-up scores) would be performed. However, often a baseline measurement of the outcome is available or feasible to obtain. An analysis of covariance (ANCOVA) using both the baseline and follow-up score of the outcome will then have more power. We calculate the efficiency of an ANCOVA analysis using the baseline scores compared with an analysis on follow-up scores only. The sample size for such an ANCOVA analysis is a factor r2 smaller, where r is the correlation of the cluster means between baseline and follow-up. This correlation can be expressed in clinically interpretable parameters: the correlation between baseline and follow-up of subjects (subject autocorrelation) and that of clusters (cluster autocorrelation). Because of this, subject matter knowledge can be used to provide (range of) plausible values for these correlations, when estimates from previous studies are lacking. Depending on how large the subject and cluster autocorrelations are, analysis of covariance can substantially reduce the number of clusters needed.

Systematic Care for Caregivers of Patients With Dementia: A Multicenter, Cluster-Randomized, Controlled Trial

BackgroundA multifaceted implementation (MFI) strategy was used to implement an evidence-based occupational therapy program for people with dementia (COTiD program). This strategy was successful in increasing the number of referrals, but not in improving occupational therapists’ (OTs) adherence. Therefore, a process evaluation was conducted to identify factors that influenced the effectiveness of the MFI strategy.MethodsA mixed-method approach of qualitative and quantitative research was used to evaluate the implementation process. The MFI strategy as planned and as executed were reported and evaluated based on the framework of Hulscher et al. (2003; 2006). Data on OTs attitudes and expected barriers were collected at baseline from 94 OTs using a 19-item questionnaire. Data on the experiences were collected after finishing the implementation using focus groups with OTs and telephone interviews with physicians and managers. For quantitative data, frequencies and correlations were calculated and qualitative data were analyzed using inductive content analysis.ResultsThe implementation strategy as executed had a stronger focus than planned on increasing OTs promotional skills due to an initial lack of referrals. This resulted in less attention for increasing OTs’ skills in using the COTiD program as initially intended. At baseline, OTs had a positive attitude toward the program, however, 75% did not feel experienced enough and only 14.3% felt competent in using the program. Focus groups and interviews revealed various determinants that influenced implementation. Most managers were positive about the program. However, the degree of operational support of managers for OTs regarding the implementation was not always adequate. Managers stated that a well-defined place for occupational therapy within the dementia care network was lacking although this was perceived necessary for successful implementation. Several physicians perceived psychosocial interventions not to be in their area of expertise or not their responsibility. All professionals perceived inter-professional collaboration to be a facilitator for effective implementation, and general practitioners were perceived as key partners in this collaboration. However, collaboration was not always optimal. OTs indicated that increasing the referral rate was most effective when promoting OT via other disciplines within a physician’s network.ConclusionOur data suggests that a first step in successful implementation should be to make sure that individual and organizational barriers are resolved. In addition, implementation should be network-based and encourage inter-professional collaboration. Initial promotion of COTiD should focus on physicians that have a positive attitude toward non-pharmacological interventions.
