The Effects of Motivational Interviewing Program with Health Coaching of Hypertension Patients with 3 Stage Chronic Kidney Disease on Sodium Consumption, Blood Pressure and Estimated Glomerular Filtration Rate

Abstract

The objective of this quasi-experimental research was to examine the effects of a motivational interviewing program with health coaching on sodium consumption, blood pressure and estimated glomerular filtration rate among hypertensive patients with stage 3 chronic kidney disease in Rongkwang Hospital and Banweing Health Promotion Hospital, Phrae province. This study was conducted between May and December 2022. Participants were 39 hypertensive patients with stage 3 chronic kidney disease who came for annual blood tests at Rong Kwang Hospital and further treatment at Ban Wiang Health Promoting Hospital and had an estimated glomerular filtration rate (eGFR) between 30 and 59 ml/min/1.73 m2. The research tool was a motivational interviewing program with health coaching techniques. This program provided individual consultations for 10-15 minutes each time and followed up at the participants' homes in the first week of the month, three times. A sodium consumption record form, a blood pressure level, an estimated glomerular filtration rate (eGFR), and the participant's identification book were used to collect data. Sodium consumption, level of blood pressure, and an estimated glomerular filtration rate (eGFR) were assessed six months after enrolling in the program. Data was analyzed using descriptive statistics and a paired t-test.

The results showed that after receiving a Motivational Interviewing program with Health Coaching, the participant's sodium consumption decreased from 1.22 to 0.77, the mean systolic blood pressure decreased from 133.69 to 127.28 mmHg, the mean diastolic pressure decreased from 82.44 to 78.18 mmHg, and the mean glomerular filtration rate increased from 51.59 to 53.14 ml/min/1.73m, which is significantly significant (p-value <0.05). This research indicates that a motivational interview program with health coaching helps patients change their appropriate health behaviors. Also, It can slow down the severity of chronic kidney disease and reduce the complications from the disease.
