Abstract

Background: Inappropriate antibiotic use contributes significantly to antibiotic resistance (ABR), particularly in low- and middle-income countries. Understanding community-level knowledge, attitudes, and practices is essential for designing effective interventions. This study assessed Knowledge, Attitudes and Practices (KAP) related to antibiotic use, with consideration of awareness of antibiotic resistance, in Montserrado County, Liberia. Methods: A community-based cross-sectional survey was conducted among 1160 adults in Montserrado County, Liberia, using a structured questionnaire to assess knowledge, attitudes, and practices (KAP) related to antibiotic use and antibiotic resistance. Composite KAP scores were calculated from Likert-scale items and subsequently categorized into ordered levels (poor, moderate, and good) based on percentile thresholds. Ordinal logistic regression was used to examine associations between sociodemographic characteristics and KAP outcomes. Results are presented as crude and adjusted odds ratios (COR, AOR) with 95% confidence intervals (CI), and statistical significance was set at p < 0.05. Results: Participants demonstrated moderate knowledge, with correct identification of antibiotic use for bacterial infections (skin infections: 78.8%; ear infections: 76.8%), but widespread misconceptions were observed, including use for colds and flu (73.6%) and diarrhea (80.7%). Attitudes were mixed, with many recognizing inappropriate use, yet expectation-driven demand remained common (62.7% dissatisfied when antibiotics were not prescribed; 80.9% willing to suggest antibiotics to clinicians). Practices were inconsistent, with both appropriate and inappropriate behaviors reported. While 46.2% of participants always completed antibiotic courses, inappropriate practices were frequent, including antibiotic use for common symptoms (38.6%), preventive use (37.2%), and self-medication without prescription (20.1% always). In multivariable analysis, older age was associated with higher knowledge (AOR = 3.82, 95% CI: 1.26–11.1), while lower education predicted poorer knowledge and practices (e.g., AOR = 0.25, 95% CI: 0.07–1.00). Urban residence was associated with poorer practices (AOR = 0.42, 95% CI: 0.29–0.61). Conclusions: While overall knowledge of antibiotic use in Montserrado County is moderate, critical misconceptions remain, and appropriate practices are inconsistent. Weak relationships between knowledge, attitudes, and practices highlight the limitations of knowledge-based interventions alone. Efforts to improve antibiotic use should address structural drivers, including access to antibiotics, healthcare-seeking behavior, and regulatory enforcement, through targeted and context-specific strategies.
