Costs of hospital care for hypertension in an insured population without an outpatient medicines benefit: an observational study in the Philippines

Abstract
Hypertension is the number one attributable risk factor for death throughout the world and a major contributor to morbidity, mortality, and increasing health care expenditures in the Philippines. Lack of access to outpatient antihypertensive medicines leads to avoidable disease progression and costly inpatient admissions. We estimated the cost to the Philippine Health Insurance Corporation (PhilHealth), which generally does not cover outpatient medicines, for inpatient care for hypertension and its sequelae.
