Self-medication with ophthalmic drugs and its associated factors among ophthalmic patients attending three hospitals in Asmara, Eritrea: a cross-sectional study

Abstract

Objective

To assess the prevalence and practice of self-medication and its associated factors among ophthalmic patients.

Design

An analytical cross-sectional study design was employed.

Setting

Three hospitals inAsmara, Eritrea.

Participants

Samples of ophthalmic outpatients aged >18 years who visited the three hospitals in Asmara, Eritrea. Systematic random sampling was used to select the study participants.

Data collection and analysis

Data were collected from September 2021 to October 2021 in a face-to-face interview using a structured questionnaire. The collected data were double entered and analysed using CSPro (V.7.2) and SPSS (V.26), respectively. Descriptive statistics and logistic regression were performed. P values less than 0.05 were considered as significant.

Primary and secondary outcome measures

Main outcome variable was practice of self-medication with ophthalmic drugs (SMOD). Secondary outcome measure was the determinants of self-medication practice.

Results

A total of 351 participants were recruited with a response rate of 97.7%. The prevalence of SMOD was found to be 14.9% (95% CI (11.1% to 18.7%)). The most frequently preferred ophthalmic drug groups were antibiotics (63.6%), followed by corticosteroids (22.7%). The main reasons for SMOD were easy accessibility (52.9%) and previous familiarity of the eye medication (27.5%). Eye redness (n=19/51) and foreign body sensation (n=18/51) were the most self-recognised complaints that required self-medication. The most common source of information for SMOD was pharmacy professionals (41.1%). Only attitude score (Crude odds ratio (COR)= 1.25, 95% CI 1.12, 1.39) was significantly associated with the practice of SMOD at bivariate logistic regression.

Conclusion

Though the majority of respondents considered self-medication with ophthalmic drugs as inappropriate, a significant number of them practising it. This mandates relevant bodies to take stricter measures to protect the public from the misuse of eye medications.
