Assessing patient understanding of their antimicrobial treatment: How are we doing and how might we improve?

Background: The Antimicrobial Stewardship Clinical Care Standard states that patients should receive certain information about their antimicrobial therapy. How well the patient communication recommendations of the standard are followed in clinical practice is not well established. The aim of this pilot quality improvement study was to assess current practices around communication with hospitalised patients about their antimicrobial therapy, to determine compliance with current recommendations, and develop and implement quality improvement actions focused on patient communication for antimicrobial stewardship in Australia.

Methods: Adult inpatients receiving one or more antimicrobials for greater than 72 h were recruited. A survey was conducted to assess rates of compliance with requirements to inform patients about the indication, duration and potential side effects of current antimicrobial therapy; modes of delivery of information; and rates of patient satisfaction with the information provided. A paper-based survey was conducted on the general medical, infectious diseases, geriatric evaluation and management, and rehabilitation wards in a 500-bed tertiary Australian hospital. A sample size of 50 was determined as adequate for a baseline analysis of patient communication practices and the development of quality improvement resources and actions. Responses to categorical questions were analysed quantitatively, with additional feedback from patients was collated and analysed qualitatively.

Results: A total of 54 patients were surveyed. A majority (83%) of patients had been informed that they were taking antimicrobials, and, of these, 96% said they knew the indication, 18% were informed of potential side effects, and 36% knew the duration. Only 22% were informed of the review plan and 27% knew if antimicrobials would be continued on discharge. Written information was given to 11% of patients. Over half (62%) of patients either wanted more information or had concerns about their antimicrobial therapy. Patients reported difficulty in obtaining information. Fifty-eight percent of patients received antimicrobial information from doctors, 13% from nurses and 12% from pharmacists.

Conclusions: This study identified gaps in communication with patients regarding in-hospital antimicrobial therapy, and highlighted the need for development and delivery of local quality improvement activities to address this gap.
