Abstract
OBJECTIVES: The objective of this study was to explore medical practitioners' understanding of antimicrobial resistance (AMR) and its aspects, such as its causes, possible outcomes and how doctors can contribute to its prevention. DESIGN AND SETTING: This qualitative study was conducted in Sri Lankan healthcare settings. PARTICIPANTS: Using convenience sampling, the study included allopathic medical practitioners aged 18-60 years, excluding intern-medical officers, until data saturation. INTERVENTION: One-on-one interviews were conducted online or in person, depending on each participant's preference. A structured questionnaire was used to triangulate the information. RESULTS: Data were categorised into four: (1) understanding, awareness and identifying AMR as an issue among medical practitioners, (2) knowledge and understanding of factors that contribute to AMR development among medical practitioners, (3) knowledge and understanding of the outcome of AMR and (4) knowledge and understanding of preventive measures against AMR among medical officers. Interviewees showed an awareness of AMR; however, their knowledge was not up to date. Key reasons for inappropriate antibiotic use included unavailability and poor quality of antibiotics and unawareness of updated guidelines, especially in the government sector. In the private sector, patient pressure, the need to attract patients and the high cost of investigations contributed to misuse. Additionally, low patient literacy about AMR was a significant factor. CONCLUSION: This study revealed that although medical practitioners in Sri Lanka are aware of AMR, their knowledge remains limited in certain areas. Several challenges contributed to inappropriate antibiotic use, including the availability and quality of antibiotics, external pressures from patients and financial constraints. The findings of this study highlight the urgent need for continuous medical education and public awareness campaigns to improve both practitioner and patient understanding of AMR. Addressing these issues is essential for effectively preventing and managing AMR in healthcare settings in Sri Lanka.
