Patient level cost of diabetes self-management education programmes: an international evaluation

Understanding the cost of care of type 2 diabetes mellitus - a value measurement perspective

OBJECTIVES

We explore the cost of care of type 2 diabetes mellitus (T2DM) using time-driven activity-based costing (TDABC) and connect that cost to resulting patient health outcomes.

DESIGN

We construct six care pathways varying from low-risk to high-risk patients over a 12-month cycle of care. We collect time, resource and cost data on activities in each care pathway and compute a time-driven estimate of cost. Use of patient outcome data highlights the health outcomes achieved.

SETTING

Primary, secondary and tertiary care.

PARTICIPANTS

Medical staff involved in the care of patients with T2DM.

PRIMARY AND SECONDARY MEASURES

Primary: resources consumed to provide T2DM care. Secondary: health outcomes for representative patient within each patient category.

RESULTS

By computing cost of T2DM care and associated complications of chronic kidney disease, active foot disease, moderate risk of active foot disease and myocardial infarction, we show that when patients develop acute complications, significant costs are incurred, as compared with the cost of maintaining a patient at low or moderate risk. Variance analysis further informs decision making by showing the need to have the right personnel doing the right tasks at the right time to control costs.

CONCLUSIONS

A TDABC approach facilitates an understanding of the drivers of cost in chronic illness care. Our paper highlights the stages in the care pathway where different settings, decision making and a more optimal use of resources could assist with achievement of better patient outcomes.

Scalable solution for delivery of diabetes self-management education in Thailand (DSME-T): a cluster randomised trial study protocol

INTRODUCTION

Type 2 diabetes mellitus is among the foremost health challenges facing policy makers in Thailand as its prevalence has more than tripled over the last two decades, accounting for considerable death, disability and healthcare expenditure. Diabetes self-management education (DSME) programmes show promise in improving diabetes outcomes, but this is not routinely used in Thailand. This study aims to test a culturally tailored DSME model in Thailand, using a three-arm cluster randomised controlled trial comparing a nurse-led model, a peer-assisted model and standard care. We will test which model is effective and cost effective to improve cardiovascular risk and control of blood glucose among people with diabetes.

METHODS AND ANALYSIS

21 primary care units in northern Thailand will be randomised to one of three interventions, enrolling a total of 693 patients. The primary care units will be randomised (1:1:1) to participate in a culturally-tailored DSME intervention for 12 months. The three-arm trial design will compare effectiveness of nurse-led, peer-assisted (Thai village health volunteers) and standard care. The primary trial outcomes are changes in haemoglobin A1c and cardiovascular risk score. A process evaluation and cost effectiveness evaluation will be conducted to produce policy relevant guidance for the Thai Ministry of Public Health. The planned trial period will start in January 2020 and finish October 2021.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from Thailand and the UK. We will share our study data with other researchers, advertising via our publications and web presence. In particular, we are committed to sharing our findings and data with academic audiences in Thailand and other low-income and middle-income countries.
