Prevalence of antibiotic self-medication and knowledge of antimicrobial resistance among community members in Neno District rural Malawi: A cross-sectional study

Objectives

Despite global efforts to address antibiotic self-medication, it is still significantly prevalent. This study aimed to investigate the prevalence of antibiotic self-medication and assess knowledge of antibiotic resistance among community members in Neno District, rural Malawi.

Methods

A cross-sectional, community-based study was conducted from September to November 2023, using simple random sampling across 169 villages. Participants from two households per village were surveyed using a “drug bag” method, focusing on those who had taken antibiotics within the preceding 6 months. In addition, drug retailers were selected via snowball sampling for interviews.

Results

Of the 531 participants and 39 drug retailers, 71.1% reported antibiotic use, with 69.5% self-medicating in the past 6 months, with convenience (31.5%) and confidence (26.7%) being the reasons. Common symptoms prompting self-medication included cough (29.9%), sore throat (28.6%), and aches and pain (28.6%). Amoxicillin (61.1%) and cotrimoxazole (29.6%) were the most used antibiotics. More than half (53.1%) reused leftover antibiotics from health facilities, with employed participants significantly more likely to self-medicate. Awareness of antibiotic resistance was low (16.1%), mainly learned from hospitals. Unlawful antibiotic sales by drug retailers (46.2%) were noted.

Conclusions

The study highlights the urgent need for government-led efforts to regulate antibiotic use and increase public awareness to mitigate the impact on public health.
