The purpose of this study was to determine the extent of agreement between the prescription medications listed on a patient’s PIP profile and a BPMH obtained by a pharmacist. Of the 50 PIP profiles reviewed, 78% contained one or more identified discrepancies involving a prescription medication. In general, the PIP profile tended to underestimate the mean number of medications per patient (mean difference of 1.1 between numbers reported in the interview and the PIP profile; p < 0.001). These results are similar to those obtained in a recent study of the accuracy of British Columbia’s provincial drug database, PharmaNet, for medication profiles of patients with heart failure. Over 70% of the PharmaNet profiles reviewed in that study contained inaccurate or misleading information about the patient’s current medication consump­tion. The most common type of discrepancy involved medications that appeared in PharmaNet but were overdue for a refill (i.e., incorrectly appeared as inactive).

The most common prescription discrepancy identified in the study reported here was one or more of the patient’s current prescription medications incorrectly appearing inactive in the PIP profile. Sole reliance on the PIP to determine the prescrip­tion medications that a patient was taking before admission might therefore result in unintentional omissions of medica­tions. Numerous reasons for this discrepancy were identified, including recent changes to the patient’s medication or dosing regimen, whether initiated by the patient or by the physician. cialis canadian pharmacy

Often, the patient’s actual daily dose was less than the total daily dose calculated from the PIP profile. As a result, the medication dispensed would last the patient longer than the number of days’ supply suggested by the PIP profile. Therefore, a risk of prescribing too much medication exists if the PIP profile is used to calculate the dose on admission without confirming the information with the patient. Physicians must be encouraged to prescribe the dose and regimen they want the patient to follow, so that the prescription label and the PIP database are accurate. Attempts to save the patient money (by prescribing a larger dose of medication, with verbal instructions to take the medication differently from what is indicated on the prescription label) should be avoided.
