Cost-effectiveness of a multicomponent primary care program targeting frail elderly people.

BACKGROUND: Over the last 20 years, integrated care programs for frail elderly people aimed to prevent functional dependence and reduce hospitalization and institutionalization. However, results have been inconsistent and merely modest. To date, evidence on the cost-effectiveness of these programs is scarce. We evaluated the cost-effectiveness of the CareWell program, a multicomponent integrated care program for frail elderly people. METHODS: Economic evaluation from a healthcare perspective embedded in a cluster controlled trial of 12 months in 12 general practices in (the region of) Nijmegen. Two hundred and four frail elderly from 6 general practices in the intervention group received care according to the CareWell program, consisting of multidisciplinary team meetings, proactive care planning, case management, and medication reviews; 165 frail elderly from 6 general practices in the control group received usual care. In cost-effectiveness analyses, we related costs to daily functioning (Katz-15 change score i.e. follow up score minus baseline score) and quality adjusted life years (EQ-5D-3 L). RESULTS: Adjusted mean costs directly related to the intervention were €456 per person. Adjusted mean total costs, i.e. intervention costs plus healthcare utilization costs, were €1583 (95% CI -4647 to 1481) higher in the intervention group than in the control group. Incremental Net Monetary Benefits did not show significant differences between groups, but on average tended to favour usual care. CONCLUSIONS: The CareWell primary program was not cost-effective after 12 months. From a cost-effectiveness perspective, widespread implementation of the program in its current form cannot be recommended. TRIAL REGISTRATION: The study was registered in the ClinicalTrials.govProtocol Registration System: ( NCT01499797 ; December 26, 2011). Retrospectively registered.

Unravelling complex primary-care programs to maintain independent living in older people: a systematic overview.

OBJECTIVES: Complex interventions are criticized for being a "black box", which makes it difficult to determine why they succeed or fail. Recently, nine proactive primary-care programs aiming to prevent functional decline in older adults showed inconclusive effects. The aim of this study was to systematically unravel, compare, and synthesize the development and evaluation of nine primary-care programs within a controlled trial to further improve the development and evaluation of complex interventions. STUDY DESIGN AND SETTING: A systematic overview of all written data on the nine proactive primary-care programs was conducted using a validated item list. The nine proactive primary-care programs involved 214 general practices throughout the Netherlands. RESULTS: There was little or no focus on the (1) context surrounding the care program, (2) modeling of processes and outcomes, (3) intervention fidelity and adaptation, and (4) content and evaluation of training for interventionists. CONCLUSIONS: An in-depth analysis of the context, modeling of the processes and outcomes, measurement and reporting of intervention fidelity, and implementation of effective training for interventionists is needed to enhance the development and replication of future complex interventions.

The association between implementation and outcome of a complex care program for frail elderly people.

Background: Over the last 20 years, the effectiveness of complex care programs aiming to prevent adverse outcomes in frail elderly people has been disappointing. Recently, we found no effectiveness of the CareWell primary care program. It is largely unknown to what extent incomplete implementation of these complex interventions influences their outcomes. Objective: To examine the association between the degree of implementation of the CareWell program and the prevention of functional decline in frail elderly people. Methods: Quantitative process evaluation conducted alongside a cluster-controlled trial. Two hundred and four frail elderly participants from six general practitioner practices in the Netherlands received care according to the CareWell program, consisting of four key components: multidisciplinary team meetings, proactive care planning, case management and medication reviews. We measured time registrations of team meetings, case management and medication reviews and care plan data as stored in a digital information portal. These data were aggregated into a total implementation score (TIS) representing the program's overall implementation. We measured functional decline with the Katz-15 change score (follow-up score at 12 months minus the baseline score). The association between TIS and functional decline was analyzed with linear mixed model analyses. Results: We found no statistically significant differences in functional decline between TIS groups (F = 1.350, P = 0.245). In the groups with the highest TISs, we found more functional decline. Conclusion: A higher degree of implementation of the CareWell program did not lead to the prevention of functional decline in frail elderly people.

Multicomponent Program to Reduce Functional Decline in Frail Elderly People: A Cluster Controlled Trial.

BACKGROUND: The increasing number of community-dwelling frail elderly people poses a challenge to general practice. We evaluated the effectiveness of a general practitioner-led extensive, multicomponent program integrating cure, care, and welfare for the prevention of functional decline. METHODS: We performed a cluster controlled trial in 12 general practices in Nijmegen, the Netherlands. Community-dwelling frail elderly people aged ≥70 years were identified with the EASY-Care two-step older persons screening instrument. In 6 general practices, 287 frail elderly received care according to the CareWell primary care program. This consisted of proactive care planning, case management, medication reviews, and multidisciplinary team meetings with a general practitioner, practice and/or community nurse, elderly care physician, and social worker. In another 6 general practices, 249 participants received care as usual. The primary outcome was independence in functioning during (instrumental) activities of daily living (Katz-15 index). Secondary outcomes were quality of life [EuroQol (EQ5D+C) instrument], mental health and health-related social functioning (36-item RAND Short Form survey instrument), institutionalization, hospitalization, and mortality. Outcomes were assessed at baseline and at 12 months, and were analyzed with linear mixed-model analyses. RESULTS: A total of 204 participants (71.1%) in the intervention group and 165 participants (66.3%) in the control group completed the study. No differences between groups regarding independence in functioning and secondary outcomes were found. CONCLUSION: We found no evidence for the effectiveness of a multifaceted integrated care program in the prevention of adverse outcomes in community-dwelling frail elderly people. Large-scale implementation of this program is not advocated.

Development of an instrument for the identification of frail older people as a target population for integrated care.

BACKGROUND: Primary care is increasingly interested in the identification of frailty, as it selects the target population for integrated care. However, instruments for the identification of frailty specifically validated for use in primary care are scarce. This study developed the Easycare Two-step Older persons Screening (Easycare-TOS), which provides a valid, efficient, and pragmatic screening procedure to identify frail older people. AIM: This paper aims to describe the development of the Easycare-TOS and the data from the pilot studies. DESIGN AND SETTING: Observational pilot study in seven academic GP practices in and around Nijmegen, The Netherlands. METHOD: The Easycare-TOS was developed in a cyclic process with the input of stakeholders. In every cycle, the requirements were first defined, then translated into a prototype that was tested in a pilot study. The Easycare-TOS makes optimal use of prior knowledge of the GP, and the professionals' appraisal is decisive in the frailty decision, instead of a cut-off score. Further, it considers aspects of frailty, as well as aspects of the care context of the patient. RESULTS: The pilot data have shown that after step 1, two-thirds of the patients do not need further assessment, because they are judged as not frail, based on prior knowledge of the GP. The overall prevalence of frailty in this pilot study is 24%. Most professionals who participated in the pilot studies considered the time investment acceptable and the method to be of added value. CONCLUSION: The Easycare-TOS instrument meets the predefined efficiency, flexibility, and acceptability requirements for use as an identification instrument for frailty in primary care.

The CareWell-primary care program: design of a cluster controlled trial and process evaluation of a complex intervention targeting community-dwelling frail elderly.

BACKGROUND: With increasing age and longevity, the rising number of frail elders with complex and numerous health-related needs demands a coordinated health care delivery system integrating cure, care and welfare. Studies on the effectiveness of such comprehensive chronic care models targeting frail elders show inconclusive results. The CareWell-primary care program is a complex intervention targeting community-dwelling frail elderly people, that aims to prevent functional decline, improve quality of life, and reduce or postpone hospital and nursing home admissions of community dwelling frail elderly. METHODS/DESIGN: The CareWell-primary care study includes a (cost-) effectiveness study and a comprehensive process evaluation. In a one-year pragmatic, cluster controlled trial, six general practices are non-randomly recruited to adopt the CareWell-primary care program and six control practices will deliver 'care as usual'. Each practice includes a random sample of fifty frail elders aged 70 years or above in the cost-effectiveness study. A sample of patients and informal caregivers and all health care professionals participating in the CareWell-primary care program are included in the process evaluation. In the cost-effectiveness study, the primary outcome is the level of functional abilities as measured with the Katz-15 index. Hierarchical mixed-effects regression models/multilevel modeling approach will be used, since the study participants are nested within the general practices. Furthermore, incremental cost-effectiveness ratios will be calculated as costs per QALY gained and as costs weighed against functional abilities. In the process evaluation, mixed methods will be used to provide insight in the implementation degree of the program, patients' and professionals' approval of the program, and the barriers and facilitators to implementation. DISCUSSION: The CareWell-primary care study will provide new insights into the (cost-) effectiveness, feasibility, and barriers and facilitators for implementation of this complex intervention in primary care. TRIAL REGISTRATION: The CareWell-primary care study is registered in the ClinicalTrials.gov Protocol Registration System: NCT01499797.
