A Comparison of Services Provided by Pharmacists and Nurses: RESULTS

19 Aug
2010

A total of 100 subjects were recruited, 50 of whom were counselled by pharmacists and 50 by nurses. All participants completed the initial interviews over a period of 1 month. The overall mean scores for the level of satisfaction with counselling were not significantly different between patients counselled by pharmacists and those counselled by nurses (4.2 ± 0.68 and 4.3 ± 0.73, respectively; p = 0.48) (Table 1). Satisfaction scores for pharmacists and nurses were similar with regard to giving instructions on medication dose and schedule, providing information about adverse reactions, and courtesy and respect. However, there was a trend toward greater satisfaction with advice provided by nurses regarding appropriate action to be taken by the patient should a side effect occur.

Pharmacists used the written pamphlet information as a counselling aid more than nurses, and patients counselled by pharmacists had significantly greater satisfaction with the written information given to them as a take-home reference (4.1 ± 0.90 and 3.7 ± 0.84, respectively; p = 0.03).

Table 2 presents the results in terms of logistic regression predicting the odds ratio of satisfaction with counselling items. Patients counselled by pharmacists were more likely to be very satisfied with information provided about adverse effects (1.66:1). As well, patients found the written information provided by pharmacists more meaningful when used in conjunction with the pharmacist’s counselling (2.28:1).

The mean scores for patients’ knowledge about TB medications were similar for patients counselled by pharmacists and those counselled by nurses (4.7 ± 0.56 and 4.8 ± 0.49, respectively; p = 0.48) (Table 3). Fisher’s exact test was used to detect differences between the 2 groups, but the results were insignificant because of the small sample size and the small number of failures (i.e., patients coded as response unknown).
