In Bangladesh, private healthcare is common and popular, regardless of income or area of residence, making the private sector an important player in health service provision.

We conducted research in Dhaka, between 2004 and 2008, to develop and evaluate a public–private partnership (PPP) model to involve private medical practitioners (PMPs) within the National TB Control Programme (NTP)’s activities. Since 2008, this PPP model has been scaled up in two other big cities, Chittagong and Sylhet. This paper reports the results of this development, evaluation and scale-up.
