Abstract

Introduction: The rising prevalence of chronic disease is leading to an increase in the demand for primary care services and a shortage of primary care physicians globally. Addressing these challenges calls for innovations in the healthcare delivery model with greater use of healthcare technology tools. We previously examined the feasibility of using an automated healthcare kiosk for the management of patients with stable chronic disease in the primary care setting. The aim of this follow-up study is to evaluate the health outcomes of patients with chronic disease who are on kiosk management compared with patients who are on routine management by nurse clinicians.

Methods and analysis: The pilot study will be a two-armed randomised controlled trial of 120 patients with well-controlled chronic disease on 4-monthly follow-up visits over a 12-month period. Patients with prior diagnoses of hypertension, hyperlipidaemia and/or diabetes will be included in the study and will be randomly assigned to intervention or control groups to receive kiosk or nurse management, respectively. The main primary outcome measure is the overall chronic disease control of the patients. Other primary outcome measures are the blood pressure and low-density lipoprotein cholesterol levels for patients without diabetes, and blood pressure, low-density lipoprotein cholesterol and haemoglobin A1c levels for patients with diabetes. Secondary outcome measures are visit duration, patient satisfaction with the management process, health-related quality of life and the occurrence of any adverse event. Data will be captured longitudinally at baseline, 4 months, 8 months and 12 months, and will be analysed using multiple regression models.

Ethics and dissemination: The study has been approved by the Singapore Health Services (SingHealth) Centralised Institutional Review Board (2017/2715). Findings of the study will be submitted for publication in peer-reviewed journals and presented at national and international conferences.
