The Healthy Hearts program to improve primary care for hypertension in seven rural health units of Iloilo Province, Philippines: a comparative cost study.

Abstract

Background: In 2021, the Philippines launched the Healthy Hearts demonstration project for delivering hypertension (HTN) services in seven Rural Health Units (RHUs) in District 1 of Iloilo Province, West Visayas Region. This study evaluates the provider time cost and medication cost of delivering these services under three medication procurement scenarios, projecting them to the district and province levels to inform scaling-up efforts.

Methods: A mixed-methods design was used for cost data collection, including key informant interviews (KII), focus group discussions (FGD), and secondary data sources. The HEARTS costing tool was adapted to analyze program costs per patient from the health system perspective. Three scenarios were assessed, depending on the procurement scheme of HTN medications: baseline local government procurement, pooled procurement through the Philippine Pharma Procurement Inc. (PPPI) national pooling mechanism, and private pharmacy outsourcing. We assessed annual provider labor costs and medication costs per patient for each scenario.

Results: The average provider cost per patient was considerably lower for patients with controlled HTN than for patients with uncontrolled HTN: USD 5 (range USD 3.4-6.1 across RHUs) vs. USD 32.9 (range USD 28.8-38.4)) due to the need for more frequent follow-up visits for the latter. Average medication costs per patient were estimated at USD 9.1 (range USD 7.2-11.5) using local procurement prices, USD 2.9 (range USD 2.3-3.7) using PPPI pooled procurement prices, and USD 23 (range USD 17.9-30.5) using private pharmacy outsourced prices. The higher medicine costs in the pharmacy outsourcing scenario were partially offset by lower provider costs (an average reduction of USD 1.5 per patient per year) due to reduced on-site dispensing time in this scenario.

Conclusions: The findings from this study indicate two key opportunities for cost savings in HTN management in the Philippines' rural health units system: 1) enhancing the control of HTN, thereby reducing the need for follow-up visits and cutting down on provider time costs, and 2) utilizing pooled medication procurement mechanisms such as through the Philippine Pharma Procurement Inc. Provider time costs can also be partially reduced through outsourcing the dispensing of medications to private pharmacies, although doing so is currently associated with higher medication costs, further underscoring the utility of pooled procurement mechanisms for essential hypertension medicines.
