Mwayi’s research interests are mainly on economic evaluations of surgical interventions in low-and middle-income countries (LMICs). His most recent research has been focused model-based economic evaluations of perioperative interventions among patients undergoing elective and emergency abdominal surgery in LMICs. His next research output is on the cost-effectiveness of sterile glove and instrument change before closing the abdominal wound to reduce surgical site infections.

Mwayi has finalised two cost assessments. The first assessed the cost of abdominal tuberculosis in India and the second assessed the cost of laparotomy in Nigeria.   

Mwayi Kachapila joined the University of Birmingham in 2019. Prior to that, he worked for the Ministry of Health in Malawi as a Health Economist responsible monitoring and evaluation.

Since joining the University of Birmingham Mwayi has conducted economic evaluations surgical interventions in Low-and Middle-Income Countries (LMICs) and one was published by PLoS One.

Mwayi has developed decision analytic models for assessing the potential cost-effectiveness of perioperative interventions of reducing postoperative complications in LMICs. He assessed the economic burden of untreated appendicitis.

Currently Mwayi is giving health economics input on the planned PENGUIN trial and involved in a project aimed at estimating the economic burden of untreated surgical conditions focusing on LMICs.

Mwayi supports teaching of the Introduction to Health Economics module by delivering a lecture on economic evaluation in an international context.
