Class of 2007 Abstract / Objectives: Medication reconciliation is a formal process of obtaining a complete and accurate list of each patient’s current home medications. This process is done to prevent errors of omission, therapeutic duplication, dosing/frequency errors, or drug-drug/drug-disease interactions. As of January 1, 2006, University Medical Center (UMC) implemented a new, comprehensive medication reconciliation form which was intended to prevent medication-related discrepancies upon admission. The purpose of this study was to compare the percent of missing required prescription information upon hospital admission before and after the implementation of the medication reconciliation form.
Methods: This study was an inferential retrospective chart review of patients admitted to UMC in Tucson, Arizona, between January 1, 2005 and August 1, 2006. While the overall goal was to measure the impact of a new medication reconciliation form on the completeness of a patient's medication history, the specific study objectives were to: (1) evaluate medication reconciliation form utilization and compliance and (2) compare the completeness of medication information upon hospital admission before and after the implementation of the comprehensive medication reconciliation form. Patients were included in the study if they were over 18 years of age and admitted to UMC at least once in 2005, and at least once between January 1, 2006 and August 1, 2006. The following patients were excluded: patients that were institutionalized in an assisted living facility or nursing home, admitted to the emergency room, intubated, transferred to the hospital from a nursing home or a long term care facility, and discharged from the hospital within 24 hours of admit. Two hundred and thirty-four patients, who met the inclusion criteria, were randomly selected from a UMC hospital census. The researchers reviewed each medical chart and recorded the physician-reported medication history, reason for admit, length of stay, and demographic information. Descriptive and inferential statistical analysis was completed using SPSS Version 11.0 (SPSS Inc., Chicago, IL). After collecting the data, counts were taken on missing prescription information, such as missing medication names, dose, route, and frequencies. If the collected data were normally distributed and were interval/ratio level data, a paired t- test was used for analysis. If the data were not normally distributed or were of nominal/ordinal level, a McNemar test was used. An a priori alpha level of 0.05 was used for all statistical tests.
Results: A total of 234 patients were included in both the pre and post analysis. Approximately 53.8% of the sample was male. Fifty-one percent of the population was categorized as white in the patient’s chart. The average age at time of first admit was 50.3 years. Fifty-three percent of the population had a past medical history that included cardiovascular disease. Over 28% of the patients in the sample had diabetes and over 18% had pulmonary disease. The most common admit diagnoses for the population included shortness of breath, chest pain, and abdominal pain. Medication reconciliation forms were found in the chart 71.4% of the time. Of the 71.4% of the forms present in the patient’s medical chart, the form was utilized 66.6% of the time. The percentage of allergies recorded in the patient’s chart decreased from 89.3% before implementation of the form to 65.9% after implementation. This movement repeated itself with the recording of social history, which fell from 92.3% recorded before the form to 52.6% after implementation. Introduction of the new medication reconciliation form at UMC resulted in significantly fewer drug names missing, incorrect, or illegible from the patient’s medication history between pre and post (p=0.034), as well as a greater amount of medications recorded in the patient’s medication history (p=0.006). However, the use of the form did not result in significant differences between pre and post in the route, frequency, and dosing information being recorded. It also did not result in a significantly greater amount of non- prescription drugs recorded.
Conclusions: The results of this study indicate the need for a systematic approach to ensure the process of obtaining accurate medication histories at the time of hospital admission. Utilization of a new comprehensive medication reconciliation form in this academic institution is far from optimal, and could have significant healthcare implications. Better methods of ensuring medication reconciliation at the time of hospital admission are needed.
