In Nepal, the estimated incident cases are 0.07 million, of them, 0.03 million people are diagnosed and enrolled in the treatment annually, and numbers of undiagnosed people living with tuberculosis (TB) might be a threat to achieving END TB strategy targets. Understanding health-seeking behaviour and care pathways is crucial to reducing missed cases and decreasing TB transmission. The objective of the study was to identify the health-seeking behavior of TB patients and understand the reasons behind TB diagnostic and treatment delays in Nepal. This was a cross-sectional, population-based survey carried out in 99 clusters of 55 districts (total of 77) of Nepal. Primary Sampling Units were Village Development Committees or Municipalities and wards selected using systematic proportional to population size method. Of the total 54,200 people who attended in the survey, 1,825 had a history of TB and asked their health-seeking practice. 62% and 72% of the TB patients utilised the government health facilities for diagnosis and treatment. 18% of the TB patients said that they received diagnosis services, and 16% of patients took their treatment from outside of the country, especially India, due to fear of stigma and easy access to the services. The majority of the TB patients utilised government health facilities to receive diagnosis and treatment services. Some of the participants sought TB services from private health care providers, and a significant proportion of participants received them from India due to difficulty in accessing local services and fear of stigma and discrimination.
