Abstract
The objective of this study was to investigate the extent of non-adherence to prescribed antibiotics and the relationship of non-adherence to consultation and attitudinal factors. Self-completion postal questionnaires were sent to 202 consecutive adult attenders to an accident and emergency (A&E) department who had been given antibiotics to take home, within a week of the A&E attendance. The questionnaire included a detailed log of dosing, two sections of eight questions each on the patients’ perceptions of the consultation and of their attitudes to medicines in general, which were marked on Likert scales; and questions inviting free text answers. Efforts were made to maximize the response rate, and to contact a random sample of 10 non-responders to assess any non-response bias. The response rate was 56%. The non-responders sampled reported similar non-adherence to that of the responders. Of the 113 responders, 10 (9%) indicated that they had taken none of their prescribed medicines, and 25 (22%) that they had taken less than 80%. The most common pattern of non-adherence was early cessation. Two aspects of the consultation (expectations about a prescription, and that there were too many tablets) were related to adherence. In conclusion, this study suggests that the effectiveness of some A&E consultations is reduced by inadequate exploration of patients’ concerns and expectations.
