With the aging of the population and changes in the disease spectrum, the incidence of multimorbidity among the elderly remained high, and have become the focus of the family doctor contracting service at the primary level. At present, there are many studies promoting the signing of family doctors from the perspective of increasing "quantity", but there is still a lack of studies on the factors affecting the effectiveness of family doctor contract services for elderly multimorbidity patients after signing from the perspective of improving "quality".

To explore the important influencing factors of satisfaction and usefulness evaluation of elderly multimorbidity patients with family doctor contract services in urban communities of guangdong province, and to provide a basis for future improvement of multimorbidity management services at the grassroots level.

From September to December 2022, elderly patients with multiple chronic conditions in the community of Guangdong Province (Shenzhen, Zhanjiang and Meizhou) were selected by multi-stage stratified whole cluster random sampling method and surveyed by self-administered questionnaire. Multifactorial Logistic regression analysis was used to explore the influencing factors of satisfaction and usefulness evaluation of family doctor contracting services for elderly multimorbidity patients.

A total of 636 valid questionnaires were collected, with effective recovery rate of 99.69% (636/638). There were 624 family doctors who were relatively satisfied/very satisfied, accounting for 98.11%; The service usefulness evaluation of family doctors was slightly helpful/greatly helpful to 625 people, accounting for 98.27%. The results of multivariate Logistic regression analysis showed that patients with general satisfaction of family doctor contract service were taken as reference. Patients with hyperlipidemia (OR=15.203), disease duration <3 years (OR=48 703 577.681), 4 chronic diseases (OR=135.131), and severe dependence on self-care ability (OR=668 738.913) were more likely to make satisfactory evaluations than patients with complete self-care. Patients with annual personal income of ≤ 30 000 yuan (OR<0.001), >30 000-50 000 yuan (OR<0.001), >50 000-100 000 yuan (OR<0.001) were less likely to make a satisfactory evaluation than patients with income >100 000-200 000 yuan (P<0.05). Patients aged 65-69 years (OR=12.573) were more likely to be very satisfied than those aged ≥70 years, and those with 4 chronic diseases (OR=135.131) were more likely to be very satisfied than those with 5 or more chronic diseases. The average annual income of individuals was ≤ 30 000 yuan (OR<0.001), >30 000-50 000 yuan (OR<0.001), and some understanding of the disease (OR=0.013) or more understanding (OR=0.035) patients were less likely to give a very satisfactory evaluation (P<0.05). Multivariate Logistic regression analysis of the evaluation of the effectiveness of family doctor contract services by elderly patients with comorbidity of chronic diseases showed that taking the family doctor contract service as not very useful as the dependent variable, patients aged 65-69 years old (OR=28.710) were more likely to make a slightly helpful evaluation than patients aged ≥70 years old. Working patients (OR=0.091) were less likely to give a slightly helpful evaluation than unemployed patients (P<0.05). Patients aged 65 to 69 years (OR=56.795) were more likely to make helpful evaluations than those aged ≥70 years, and patients with chronic heart failure (OR=0.023) were less likely to make helpful evaluations than those without the disease (P<0.05) .

The overall level of satisfaction and usefulness evaluation of family doctors contracted services of elderly multimorbidity patients in urban communities of Guangdong province is relatively high, both above 95%, which is influenced by a combination of factors, including changing the type of chronic disease, annual income, knowledge of the condition, and self-care ability. In the future, we should continue to standardize and improve the connotation of family doctor contracted services, optimize the management mode of key populations such as elderly multimorbidity, improve the satisfaction and sense of gain of patients, so as to ultimately enhance the effectiveness of family doctor contracted services.
