Antimicrobial resistance has become increasingly dire as the rapid emergence of drug resistance, especially gram-negative pathogens, has outpaced the development of new antibiotics. At a recent virtual symposium, Dr Hsu Li Yang, Vice Dean (Global Health) and Programme Leader (Infectious Diseases), NUS Saw Swee Hock School of Public Health, presented epidemiological data on multidrug-resistant (MDR) gram-negative bacteria (GNB) in Asia, while Dr Tan Thuan Tong, Head and Senior Consultant, Department of Infectious Diseases, Singapore General Hospital (SGH), focused on the role of ceftazidime-avibactam in MDR GNB infections. Dr Andrea Kwa, Assistant Director of Research, Department of Pharmacy, SGH, joined the panel in an interactive fireside chat, to discuss challenges, practical considerations, and solutions in MDR gram-negative infections. This Pfizer-sponsored symposium was chaired by Dr Ng Shin Yi, Head and Senior Consultant of Surgical Intensive Care, SGH.

Poor eye drop technique highly prevalent

29 Jul 2020

In a real-world setting, patients often have trouble with using eye drop bottles, which may lead to suboptimal technique, a recent study has found.

Researchers conducted a cross-sectional analysis of 678 adult participants (mean age, 68.9±12.4 years) who had already been using eye drops for at least one month. Participants demonstrated their administration technique and accomplished a questionnaire afterwards.

More than a third (35.8 percent; n=243) of the participants reported never washing their hands prior to using the eye drops. Almost all (98.0 percent) of the participants were able to get at least one drop into the eye, though 14 percent (n=95) required several attempts in order to achieve this. A total of 189 enrolees were using multiple eye drops, of whom 24 percent did not wait 5 minutes in between administrations.

Only twenty participants (3 percent) were able to administer eye drops perfectly, performing each step correctly.

The most common error was failure to perform nasolacrimal occlusion for at least 1 minute, which almost everyone committed (94.7 percent; n=642). Other common deviations were failing to close the eye (67.8 percent; n=460) and touching the bottle to the eye or eyelid (40.7 percent; n=276).

Questionnaire responses revealed that while participants generally did not regard drop instillation as a difficult process (median difficulty score, 1), some had trouble with successfully getting a drop into their eyes (18.3 percent) and squeezing the bottle (12.2 percent; n=83), and some complained about too many drops coming out of the bottle (14.6 percent; n=99).
