Study on the application effect of the family doctor contract service mode of ‘basic package+personalised package’ in elderly hypertension management in Chengdu, China: a retrospective observational study

Objectives We conducted this study to assess the application effect of the family doctor contract service mode of ‘basic package+personalised package’ in the management of hypertension patients. Design Observational study. Setting The study was conducted at a community health centre in Southwest China. Data were collected from 1 January 2018 to 31 December 2020. Participants From 1 January 2018 to 31 December 2020, hypertensive patients (age ≥65 years) who participated in the contract services of family doctors at a community health service centre in Chengdu, Southwest China, were selected as the study subjects. Main outcome measures The primary outcomes included mean blood pressure (systolic, diastolic) and the rate of blood pressure control, secondary outcomes included the level of cardiovascular disease risk and self-management ability. Assessments of baseline and 6 months after signing up were conducted on all outcomes. The major statistical analysis methods included two independent sample t-tests, paired t-tests, Pearson’s χ 2 test, McNemar’s test, two independent sample Mann-Whitney U tests and paired sample marginal homogeneity tests. Results Of the 10 970 patients screened for eligibility, 968 (8.8%) were separated into an observation group (receiving ‘basic package+personalised package (hypertension)’ service) (n=403) and a control group (receiving ‘basic package’ service) (n=565) according to the type of service package they received. In comparison to the control group, the observation group had lower mean systolic blood pressure (p=0.023), higher blood pressure control rate (p<0.001), lower cardiovascular disease risk level (p<0.001) and higher self-management ability level (p<0.001) at 6 months after signing up. The mean diastolic blood pressure of the two groups was not significantly different (p=0.735). Conclusions The family doctor contract service model of ‘basic package+personalised package (hypertension)’ has a good application effect in the management of elderly hypertension, which can improve the average blood pressure, the rate of blood pressure control, the level of cardiovascular disease risk and self-management ability of the elderly with hypertension.
