Background: To improve the effectiveness of community-based care programs, especially those targeting the oldest-old population (80+), data are needed that elucidate those factors associated with a successful response to the intervention. Two comparable nurse-led care programs have been evaluated in two large randomized controlled trials (RCTs), one in Switzerland and one in the Netherlands. Aims: To identify common patient characteristics that are related to a successful response to proactive nurse-led care, we explored if and to what extent, identical factors were present in both study populations. Methods: A secondary data analysis using trial data from the intervention group of both RCTs was conducted. The study sample consisted 461 older adults, 230 from the U-PROFIT trial (the Netherlands) and 231 from the HPC trial (Switzerland). The mean age of the total sample was 85.1 years (SD 3.7). The UPROFIT intervention, delivered by registered nurses, included a frailty assessment and a comprehensive geriatric assessment (CGA) at home followed by an individualized evidence-based care plan, care coordination, and follow-up. The HCP intervention was delivered by advanced practice nurses consisting of four home visits and three phone calls, and was guided by the principles of health promotion, empowerment, partnership, and family-centeredness. A successful response was defined as “stable” or “no decline” in daily functioning at follow-up. Daily functioning was measured with 13 items of activities of daily living and instrumental activities of daily living. Multivariate logistic regression models were applied to calculate the association between individual characteristics and a successful response. Results: Almost half of the participants in the U-PROFIT trial (50.9%), and two-thirds (65.7%) of the participants in the HCP trial had a successful response at follow-up. Fewer comorbidities and a better self-rated health had the strongest predictive value for benefiting from the intervention (OR = 0.83 [95% CI 0.66–1.03], and OR = 1.5 [95% CI 0.92–2.45]), respectively. Linking Evidence to Action: Two large RCTs demonstrated that a preventive nurse-led care program can preserve daily functioning in the oldest-old population. Older people with few comorbidities and higher self-rated health had a higher likelihood of a positive outcome. Unraveling the characteristics associated with a successful response provides important information for further refining and targeting an intervention to obtain maximum effectiveness. More effort is needed to modify interventions for the oldest-old with multiple morbidities and low levels of education
