Relationships among prescription payment methods and interactions between community pharmacists and prescribers

This research was performed to examine community pharmacists' interactions with prescribers and to determine if these interactions are related to payment method.

Randomly selected pharmacists (47 in chain pharmacies and 26 in independent pharmacies) collected data concerning prescriber interactions for a 40-hour period. These interactions were analyzed in terms of payment methods, prescriber acceptance, and types of information discussed.

Information concerning 730 interactions by 72 pharmacists was obtained. Payment methods were related to the frequency of interactions per pharmacist (p less than 0.01). There were higher percentages of interactions for self-pay (median 2.2 percent) and Medicaid (median 1.8 percent) prescriptions than for third-party fee-for-service (mode 0 percent) or capitation prescriptions (mode 0 percent). Type of information discussed was related to payment method. The vast majority of information provided by pharmacists (91 percent) was accepted by prescribers. The rate of acceptance was 97 percent for prescriber-initiated interactions versus 88 percent for pharmacist- or patient-initiated interactions (p less than 0.01).

Relationships between payment method and interactions were identified. These findings may be attributable to prescribing policies and reimbursement policies. Prescribing policies that restrict prescribers to a formulary may help make them become more adept at using those products; thus, they will make fewer prescribing errors. Reimbursement policies that require patients to consistently use a specific pharmacy (i.e., capitation) may help pharmacists become more familiar with the patient's prescription history. Therefore, interactions with prescribers are needed less frequently for these patients' prescriptions.
