BackgroundAssessing the quantity and quality of pharmacist-patient communication is important to create strategies for improving communication. Findings from studies on pharmacist-patient communication differ on the extent of communication by pharmacists. This disagreement could be because of different methods of data collection, samples, and concepts used to measure communication.ObjectivesThis research compared findings from 2 widely used methods of data collection (survey and observation) to identify: (1) the extent to which pharmacists ask questions to patients and provide information on directions, side effects, and adverse effect, (2) agreement between observation and patient report data on pharmacist information giving and question asking, and (3) how patient perceptions of question asking vary according to the structure of the question asked.MethodsA cross-sectional fieldwork design was used to collect data from a stratified random sample of 30 community pharmacies in Southeast and South-central Wisconsin. At each pharmacy, the dispensing pharmacist and 12 patients filling prescriptions were recruited. Each patient was observed for their interaction with the pharmacist and completed a survey while exiting the pharmacy. Both the survey and the observation tool consisted of items pertaining to recording of pharmacist information provision related to direction, side effects, and interactions, and pharmacist's question-asking behaviors. Descriptive analyses and correlations are reported.ResultsThere was good agreement between the 2 methods regarding pharmacist information provision behaviors (r=0.091, P<.001), this was less true of question asking (r=0.28, P=.034). Certain types of questions showed greater concordance with the observed pharmacist questions. Patients were less likely to report having been asked a question when it took the form of a nonspecific closed-ended questions, that is, "Do you have any questions?"ConclusionsOne of the most frequent questions pharmacists ask patients may not be either remembered or perceived by patients as a serious question, let alone an invitation to raise a concern. Secondly, during the selection of a specific method of data collection, researchers need to weigh strengths and weaknesses of various methods. Multimethod studies are encouraged.Copyright © 2011 Elsevier Inc. All rights reserved.
