Direct outpatient cost per case of acute gastroenteritis in Trinidad and Tobago, 2021

The burdens associated with acute gastroenteritis involve billions of dollars in expenses, coupled with significant morbidity and mortality globally. To reduce these burdens, health officials and policymakers require up-to-date data (health and economic) to request and allocate resources in guiding the development and implementation of preventative strategies. In 2021, the estimate for one case of acute gastroenteritis was calculated using multiple sources of data: the 2009 national health burden survey on acute gastroenteritis; a 2021 telephone survey of five major private hospitals; a 2021 telephone survey of 30 private pharmacies; and the 2021 Minimum Wages Act of Trinidad and Tobago. For each case of illness, an average cost of $1614 TTD ($238 USD) was estimated. For residents who sought private health care, the average GP visit cost was $500-$700 TTD ($73-$103 USD), while costs for medication prescribed ranged between $327 and $1166 TTD ($48-$172 USD). Productivity losses amounted to almost $21.7 million TTD ($3.2 million USD) for residents who took time off from work or required caregiving services. The overall annual cost was estimated to be $204 million TTD ($30.1 million USD) and, therefore, warrants measures by health officials to reduce the economic and social burdens of acute gastroenteritis in Trinidad and Tobago.
