OBJECTIVES

To examine the effectiveness of a patient-family (carer) partnership intervention on the BP control, self-care and self-efficacy for hypertensive people, and dyadic-relationship quality, depressive and anxiety symptoms, and health-related quality of life for the family dyads (hypertensive people and family carers) in rural communities of mainland China.

DESIGN

A randomised controlled trial.

METHODS

A total of 110 family dyads were randomly recruited from village clinics and randomly allocated to the intervention group ( = 55) or control group ( = 55). Family dyads in the control group received usual care. In addition to the usual care, family dyads in the intervention group received the individual-based, five-session patient-family (carer) partnership intervention. The primary outcomes included SBP, DBP, and the proportion of people with normal controlled BP. EuroQol five-dimensional-five-level (EQ-5D-5L) was adopted to evaluate participants' health-related quality of life. Data were collected at the baseline (T0), one-month (T1), and three-month postintervention (T2). Generalised estimating equation model was adopted to test the study hypotheses on all study outcomes.

RESULTS

Compared with the control group, hypertensive people in the intervention group had a greater reduction in SBP by 10.10 mmHg and DBP by 4.66 mmHg and a larger proportion of people with normal BP at T2, as well as statistically significant improvements at T1 and T2 in dyadic relationship, self-care, antihypertensive drug-titration rate, anxiety symptoms, and health-related quality of life. The intervention also had statistically significant positive effects on family carer's dyadic relationship and health-related quality of life at T1 and T2.

CONCLUSION

The patient-family (carer) partnership intervention has the potential to improve hypertensive people's BP control and family dyad's dyadic-relationship quality and mental health at short-to-medium term follow-ups. . This study provided evidence and direction to support healthcare providers in developing and implementing patient-family (carer) partnership intervention for hypertension care in rural areas.
