Dr. Schnipper’s studies attest to the common occurrence of unintentional medical discrepancies, pointing to the need for accurate medication histories, identifying high-risk patients for intensive interventions, and careful med rec at time of discharge.4
Other factors might come into play, says Ted Tsomides, MD, PhD, an attending physician on the HM service at WakeMed Hospital and assistant professor of medicine at the University of North Carolina’s School of Medicine in Raleigh, N.C. For example, he surmises that a “fatigue factor” sets in for some providers. “After five years of working on any initiative, people get worn out and push it to the back burner, unless they are really incentivized to stay on it,” he says.
List Capture
Medication reconciliation is a multifaceted process, and the first step is to gather the history of medications the patient has been taking. Hospitalist Blake J. Lesselroth, MD, MBI, assistant professor of medicine and medical informatics and director of the Portland Patient Safety Center of Inquiry at the Portland VA Medical Center in Oregon, points out that “the initial exposure to the patient is like a pencil sketch. You start to realize that med rec involves iterative loops of communication between you, the patient, and other knowledge resources (see Figure 1). As you start to pull in more information, you begin to complete your narrative. At the end of hospitalization, you’ve got a vibrant portrait with much more nuance to it. So it can’t be a linear process.”

The list is dynamic, especially in the ICU setting, says Gleason, where it represents only one point in time.
In a closed system, such as the Veterans Administration or Kaiser Permanente, it’s often easier to establish a patient’s ongoing medications. With an integrated electronic health record (EHR), providers can call up the patient’s list of medications during admittance to the hospital. Verifying those medications remains critical: The health record lists patients’ prescriptions, but that doesn’t always mean they have actually filled or are taking those medications.
At the Kaiser Permanente Southern California site in Santa Clarita, Calif., where hospitalist David W. Wong, MD, works, pharmacists review their medications with patients when they are admitted, provide any needed consultation, then repeat the process at discharge. “So far,” Dr. Wong says, “this has resulted in the best medication reconciliation that we’ve seen.”
Pharmacy Is Key
In 2006, Kenneth Boockvar, MD, of the James J. Peters VA Medical Center in Bronx, N.Y., found in a pre- and post-intervention study that using pharmacists to ferret out and communicate prescribing discrepancies to physicians resulted in lower risk of adverse drug events (ADEs) for patients transferred between the hospital and the nursing home.5 Likewise, Dr. Schnipper and his colleagues found that using pharmacists to conduct medication reviews, counsel patients at discharge, and make follow-up telephone calls to patients was associated with a lower rate of preventable ADEs 30 days after hospital discharge.6
At United Hospital System’s (UHS) Kenosha Medical Center campus in Kenosha, Wis., pharmacists play a key role in generating medication lists for incoming patients. Hospitalist Corey Black, MD, regional medical director for Cogent HMG, says many patients do not recall their medications or the dosages, so UHS utilizes a team approach: If patients come in during evenings or weekends, pharmacists start calling local pharmacies to track down patients’ medication lists. “We also try to have family members bring in any medication containers they can find,” he adds. Due to a Wisconsin state law mandating nursing homes to send medication lists along with patients, generating a list is much easier.
