Cost of "Ideal Minimum Integrated Care" for Type 2 Diabetes and Hypertension Patients in Cambodia Context: Provider Perspective

As in other countries worldwide, Diabetes mellitus type 2 (T2D) and hypertension (HTN) prevalence is increasing in Cambodia. The country is examining models to scale-up integrated T2D and HTN care. However, costs of integrated care in this setting are not yet well-understood. Thus, we modelled the cost of an "Ideal Minimum Integrated Care" (IMIC) package (detection, diagnosis, treatment + health education, self-management and follow-up) for T2D and HTN in Cambodia. We visualised a package - IMIC - of effective interventions for T2D and HTN inspired by SCUBY-ICP and PEN. WHO NCD and HEART Costing Tools were adapted to estimate annual total IMIC intervention cost per health centre, cost per case and cost per capita. Cost of the IMIC provides information on costs to aid decision-making on implementation. The Excel-based costing tool is easy to accomplish and can be replicated to provide more accurate results by using more precise actual input data, once these are available in the country. The projected costs of IMIC for T2D and HTN in Cambodia provides evidence to informed decision-making of relevant actors in implementing scale-up of IMIC for T2D and HTN. The model can be used in countries with similar context to calculate costs of integrated care.
