Effectiveness and Cost-Effectiveness of a People-Centred Care Model for Community-Living Older People Versus Usual Care: A Randomised Controlled Trial
Abstract
Background
There is a need for effective and cost-effective interprofessional care models that support older people to maintain their quality of life (QoL) and physical performance to live longer independently in their own homes.
Objectives
The objectives were to evaluate effectiveness, QoL and physical performance, and cost-utility of a people-centred care model (PCCM), including the contribution of clinically trained pharmacists, compared with that of usual care in primary care.
Methods
A randomised controlled trial (RCT) with a two-year follow-up was conducted. The participants were multimorbid community-living older people, aged ≥75 years. The intervention comprised an at-home patient interview, health review, pharmacist-led clinical medication review, an interprofessional team meeting, and nurse-led care coordination and health support. At the baseline and at the 1-year and 2-year follow-ups, QoL (SF-36, 36-Item Short-Form Health Survey) and physical performance (SPPB, Short Performance Physical Battery) were measured. Additionally, a physical dimension component summary in the SF-36 was calculated. The SF-36 data were transformed into SF-6D scores to calculate quality-adjusted life-years (QALYs). Healthcare resource use were collected and transformed into costs. A healthcare payer perspective was adopted. Incremental cost-effectiveness ratio (ICER) was calculated, and one-way sensitivity analysis was performed.
Results
No statistically or clinically significant differences were observed between the usual care (n = 126) and intervention group (n = 151) patients in their QoL; at the 2-year follow-up the mean difference was −0.02, (95 % CI -0.07; 0.04,p = 0.56). While the mean difference between the groups in physical performance at the 2-year follow-up was −1.02, (−1.94;-0.10,p = 0.03), between the physical component summary scores it was −7.3, (−15.2; 0.6,p = 0.07). The ICER was −73 638€/QALY, hence, the developed PCCM dominated usual care, since it was more effective and less costly.
Conclusions
The cost-utility analysis showed that the PCCM including pharmacist-led medication review dominated usual care. However, it had no effect on QoL and the effect towards physical performance remained unclear.
