OBJECTIVES: Approximately 10,000 people die from suicide annually in Bangladesh, many from pesticide poisoning. We aimed to estimate financial costs to patients and health services of treating patients with self-poisoning.

METHODS: Data on direct costs to families, sources of funds for treatment and family wealth were collected prospectively over a one-month period in 2016 at the tertiary Chittagong Medical College Hospital, Bangladesh. Aggregate operational costs to the government were calculated using annual budget, bed occupancy and length-of-stay data.

RESULTS: Agrochemicals were the most common substances ingested (58(.) 8%). Median durations of stay and of illness were 2 and 5 days, respectively. Median total cost to patients was conservatively estimated at US$ 98(.) 40, highest in agrochemical poisoning (US$ 179(.) 50), with the greatest cost due to medicines and equipment. Misdiagnosis as organophosphorus poisoning in 17(.) 0% of agrochemical cases resulted in increased cost to patients. Only 51(.) 9% of patients had indicators of wealth; 78(.) 1% borrowed money to cover costs. Conservatively estimated median healthcare costs (US$ 21(.) 30 per patient) were markedly lower than costs to patients.

CONCLUSIONS: Cost to patients of treating a case of agrochemical poisoning was approximately three times the cost of one month's essential items basket. Incorrect diagnosis at admission cost families substantial sums of money and increased length-of-stay; it cost the national government an estimated US$ 80,428(.) 80 annually. Widespread access to a list of pesticides used in self-poisoning plus greater focus on training doctors to better manage different forms of agrochemical poisoning should reduce the financial burden to patients and healthcare systems.
