More prescription drugs are dispensed by pharmacists rather than doctors in response to government healthcare reform. However, the results of our preliminary survey suggested a hypothesis that patients were not always satisfied with explanations provided by pharmacists upon dispensing, and therefore patient satisfaction might be enhanced if pharmacists spent more time on consultation services. The survey was conducted in 1,800 people. 321 people (17.8%) answered that pharmacist explanations were not sufficient or that they expected further consultation with pharmacists. The most common reason why they did not ask for consultation was that other patients were waiting (41.7%). If up to 30-minute consultation service was available at a pharmacy where patient privacy was ensured, 898 people (49.9%) answered that they wanted to use the service. The average willingness-to-pay (WTP) for the service was 338 yen and the mean WTP was 400 yen. When those who answered 0 yen were excluded, the average was 386 yen and the mean was 400 yen. The online survey revealed that some patients were not satisfied with pharmacist explanations upon dispensing, and that there was a need for consultation services at pharmacies. Many of the reasons why patients did not ask for consultation although they wanted to were attributable to pharmacies, and the survey results suggested a need for improvement in their services. In view of the WTP for the service, it is considered worthwhile to discuss the introduction of such a system for consultation services into dispensing fee.
