In the design of long-term care systems, preferences can serve as an essential indication to better tailor services to the needs, wishes and expectations of its consumers. The aim of this systematic review was to summarize and synthesize available evidence on long-term care preferences that have been elicited by quantitative stated-preference methods. The databases PubMed and Web of Science were searched for the period 2000 to 2020 with an extensive set of search terms. Two independent researchers judged the eligibility of studies. The final number of included studies was 66, conducted in 19 different countries. Studies were systematized according to their content focus as well as the survey method used. Irrespective of the heterogeneity of studies with respect to research focus, study population, sample size and study design, some consistent findings emerged. When presented with a set of long-term care options, the majority of study participants preferred to "age in place" and make use of informal or home-based care. With increasing severity of physical and cognitive impairments, preferences shifted toward the exclusive use of formal care. Next to the severity of care needs, the influence on preferences of a range of other independent variables such as income, family status and education were tested; however, none showed consistent effects across all studies. The inclusion of choice-based elicitation techniques provides an impression of how studies operationalized long-term care and measured preferences. Future research should investigate how preferences might change over time and generations as well as people's willingness and realistic capabilities of providing care.
