Demographic, and epidemiological transitions are taking place and tackling the rising burden of non-communicable diseases (NCDs) are challenges in achieving universal health coverage (UHC) in the country. Though the national health budget supports health care, 74% of total health expenditure is met by households out of pocket (OOP) which is the second highest in South-East Asia. The Government of Bangladesh (GOB) has consistently shown commitment in ensuring sustainable financing for health care. However, the high health care expenditure is on an increasing trend due to many nonfinancial reasons as well and a large proportion of OOP is spent on medicine and diagnostic tests. This study specifically focused on potential determinants of NCD services (HTN & DM) rather than wider health sectors and focused on PHC facilities only. The study also identified causes of hypertension (HTN) and Diabetes Miletus (DM) related household expenditure and recommended to overcome this extra expenditure.
