Standard Medication Reconciliation Protocol in the Primary Care Office-based Setting

This is a randomized clinical trial of the implementation and initial effectiveness of two interventions for improving medication reconciliation in primary care offices. The interventions we will test are 1) patients reviewing a printed paper copy of their EMR medication list just prior to seeing the physician and 2) medical assistants beginning the interview with an open-ended question. We will test the following two hypotheses:

1. Providing patients a paper copy of their EMR medication list upon check-in, to review for accuracy prior to their office visit, will improve the agreement between the EMR medication list and patient report during a phone interview within one week of the office visit.
2. The medical assistant practice of routinely using an open-ended question to introduce the medication review will improve the agreement between the EMR medication list and patient report during a phone interview within one week of the office visit.

The main outcome measure for this study is full agreement of prescription medications between the medication list in the electronic medical record at the conclusion of patient's office visit and the list generated by pharmacists during a phone interview performed within a week of the office visit.

The study will take place at 2-4 Cleveland Clinic Health Centers in primary care offices. A sample size of 400 patients will be enrolled: 20 pairs of physicians and medical assistants will be invited to volunteer for the study, and 20 patients per MD/MA pair will be recruited. Medical assistants will be trained in using scripted open-ended questions to begin reviewing medications with patients. The study coordinator will implement the printed list intervention by providing a paper list to patients.

Consenting patients will be randomized to one of four groups (A-D):

A: NO patient review of printed medication list \& NO open-ended question B: Patient review of printed medication list ONLY C: Open-ended question ONLY D: BOTH patient review of printed medication list \& open-ended question

To document the medications that patients report taking, a pharmacist will conduct a detailed phone interview with the patient and/or caretaker within a week of the office visit using a prepared script. The pharmacist will note any discrepancies between the EMR and the patient's/caretaker's self report. In order to be considered in full agreement, the medication list and patient report must agree on the five following elements: 1) name, 2) dose, 3) frequency, 4) route, and 5) PRN status.

Our goal is to statistically test whether the proportion of medication lists in agreement with patient report differs in the intervention group compared to the non-intervention group. First, an unadjusted analysis utilizing a difference of proportions test and linear contrasts as described in the above planned comparisons. Then, a multivariable mixed model will be used to determine the significance of the intervention with adjustment.

If the interventions are successful, they will be incorporated into a standard medication reconciliation protocol for Cleveland Clinic primary care office practice. If highly successful, this protocol could serve as a new standard for medication reconciliation in outpatient primary care practice in the United States.
