ABSTRACT
OBJECTIVES: This study aimed to explore the eye drop instillation technique of patients with glaucoma and whether a pharmacist-led counselling session can improve their technique. Patients’ perceptions of pharmacists’ role in providing the counselling were also explored.
METHODS: This cross-sectional study was conducted between December 2020 and March 2021 at Sarawak General Hospital, Malaysia. Convenience sampling was used to recruit patients with glaucoma who self-administered their eye drops. Participants’ background information were obtained using an investigator-administered questionnaire before their eye drop instillation technique was assessed. Those with imperfect techniques were counselled by a pharmacist before being reassessed. Differences in eye drop instillation competency were determined using paired T-test.
KEY FINDINGS: A total of 138 participants were recruited. Participants were on a median of two eye drops (IQR 2-4) for a median of five years (IQR 2-8). Prior to being counselled, they demonstrated a mean total of 8.4/13 steps (SD 2.33) correctly. A statistically significant improvement in eye drop instillation technique was observed post-pharmacists’ counselling, with a mean increase of 4.3 steps demonstrated correctly (95% CI, 4.0 to 4.7, P < 0.001). The majority of participants agreed that pharmacists are knowledgeable in providing counselling on eye drop administration techniques.
CONCLUSIONS: Patients with glaucoma treated at Sarawak General Hospital had imperfect eye drop instillation techniques, despite most having used their eye drops for several years. Interventions by pharmacists to improve eye drop instillation are crucial to optimise the medical treatment of patients with glaucoma.
