Reducing cardiovascular risk through a nurse-led email reminder program

Efficacy of a nurse-led email reminder program for cardiovascular prevention risk reduction in hypertensive patients: A randomized controlled trial.

A Canadian nurse-led email reminder program to assist patients in managing their cardiovascular risk factors appeared to be effective in this RCT comprising 200 patients.

Abstract

BACKGROUND:

Many strategies have been evaluated to improve the prevention and control of cardiovascular (CVD) risk factors. Nursing telephonic and tele-counseling individualized lifestyle educational programs have been found to improve blood pressure control and adherence to lifestyle recommendation. This study tested the efficacy of a nurse-led reminder program through email (NRP-e) to improve CVD risk factors among hypertensive adults.

METHODS:

All participants received usual CVD prevention and a guideline-based educational program. Subjects in the NRP-e group also received weekly email alerts and phone calls from a nurse care manager for 6 months. Emails contained a reminder program on the need for adherence with a healthy lifestyle based upon current guidelines. Follow-up visits were scheduled at 1, 3 and 6 months after enrollment; randomization was made centrally and blood samples were evaluated into a single laboratory.

RESULTS:

The final sample consisted of 98 (control) and 100 (NRP-e) subjects (mean age 59.0±14.5 years; 51.0% males). After 6 months, the following CVD risk factors significantly improved in both groups: body mass index, alcohol and fruit consumption, cigarette smoking, adherence to therapy hours, systolic and diastolic blood pressure, fasting blood glucose, low-density lipoproteins (LDL) and total cholesterol, triglycerides, and physical activity. In the NRP-e group, however, the prevalence of several behaviors or conditions at risk decreased significantly more than in the control group: obesity (-16%), low fruit consumption (-24%), uncontrolled hypertension (-61%), LDL (-56%), and total cholesterol (-40%).

CONCLUSIONS:

The NRP-e improved a range of CVD risk factors. The program had low costs, required only an average of less than 20min per day in addition to normal practice, and may deserve further evaluation for the inclusion among existing care management approaches.
