Public Knowledge, Beliefs and Behavior on Antibiotic Use and Self-Medication in Lithuania.

Abstract

Irrational antibiotic use has led society to antibiotic resistance—a serious health problem worldwide. This study aimed to assess public knowledge, beliefs, and behavior concerning antibiotic use and self-medication in Lithuania. The cross-sectional survey method was processed using a validated questionnaire in different regions of Lithuania. In total, 1005 adults completed the questionnaire and were included in the study. More than half of the respondents (61.1%) had poor knowledge of antibiotics. Almost half of the respondents incorrectly identified antibiotics as being effective either against viral (26.0%) or mixed (bacterial and viral) infections (21.7%). The respondents with lower educational qualifications (OR = 2.515; 95% CI 1.464–4.319; p = 0.001) and those from rural areas (OR = 1.765; 95% CI 1.041–2.991; p = 0.035) were significantly less knowledgeable of antibiotics. There was no significant difference between genders, different age groups, or different parenthood status. The determined level of self–medication with antibiotics was 31.0%. The men (OR = 1.650; 95% CI 1.120–2.430; p = 0.011), the respondents from rural areas (OR = 2.002; 95% CI 1.343–2.985; p = 0.001), and those without children (OR = 2.428; 95% CI 1.477–3.991; p < 0.001) were more likely to use antibiotics in self-medication. Lithuanian residents’ knowledge of antibiotics is insufficient. More information about antibiotic use should be provided by physicians and pharmacists. Self-medication with antibiotics is a serious problem in Lithuania and requires considerable attention.
