Antimicrobial stewardship and education in optometry.

CLINICAL RELEVANCE

Antimicrobial stewardship aims to improve how antibiotics are prescribed by clinicians and used by patients, to ensure safe appropriate use, and to prevent and contain antimicrobial resistance.

BACKGROUND

Australian optometrists can prescribe a range of antimicrobial agents, but to what extent they consider antimicrobial stewardship is not known. This study evaluated what final-year optometry students and optometrists understood about antimicrobial stewardship in eye care and considered relevance to oral prescribing and education.

METHODS

A knowledge, attitude, and practice (KAP) questionnaire was developed comprising four sections: i) demographic questions, ii) 10 multiple choice questions regarding Knowledge about antimicrobial agents and likely pathogens, diagnosis, treatment, and preventing resistance, iii) 10 Likert rating scale questions about thoughts and Attitudes, iv) mix of question types (5× MCQ: course of action, 16 Likert scale: confidence) related to Practice (diagnosis, management, and prescribing). Descriptive analyses were conducted (medians, mean±SD, and distributions).

RESULTS

Thirteen students and 36 optometrists completed the survey. Both groups had a good understanding of microbial resistance and antibiotic prescribing for ocular conditions; average knowledge scores were 9.2 ± 0.7 and 8.7 ± 1.1 for students and practitioners, respectively. Scores were neutral to agree for questions related to the need for more educational programs. The answers of practice-related MCQs had a dichotomy of answers indicating a diversity of opinion, as can be the case in practice. Average total practice confidence scores were approximately 57/80 for students and 68/80 for optometrists. Optometrists and students were very confident in their ability to conduct an appropriate case history and use their knowledge and clinical skills, including slit lamp anterior eye assessment. The lowest confidence scores were for conducting microbial testing, i.e. taking swabs for pathology.

CONCLUSION

Student and optometrist knowledge, attitudes, and practice around antimicrobial stewardship were high and in line with other health professions globally. There is scope for increased stewardship training.
