Importance of Medication Reconciliation in the Continuum of Care

Medication reconciliation represents a major challenge for organizations. Inaccurate admission medication histories can follow a patient throughout a hospitalization and contribute to medication errors and increased costs of care. Similarly, inaccurate discharge medication reconciliation can produce errors in medication therapy postdischarge, with an increased potential for readmission. Traditionally, organizations have utilized a variety of caregivers, including physicians and mid-level practitioners, to complete the medication reconciliation function, with the result being a fragmented process with suboptimal accuracy. Centralizing these functions with the pharmacy, using a small number of well-trained individuals, has the potential to improve the accuracy of this process while also reducing overall costs.

Poor admission medication reconciliation can follow a patient throughout his or her hospital stay and can be a major contributor to medication errors. Poor discharge planning and medication reconciliation can result in diminished quality of care, deficiencies in medication use, patient injury, and increased cost of care.

Consider the following: approximately 20% of patients experience adverse events (AEs) within 3 weeks of discharge1; nearly 1 in 3 heart failure patients is readmitted within 1 month after hospital discharge2; and 3 of every 4 postdischarge follow-up visits occur without the benefit of a discharge summary.3 A 2011 study revealed that among 564 patients discharged from a hospital to a subacute care facility, 181 (32%) had pending laboratory tests.4 Of these, only 20 (11%) of the discharge summaries provided documentation of these pending tests. Other studies have also reported relatively poor documentation of tests pending at discharge.5,6

The Impact of a Poor Discharge Process

The outcomes of poor transitions in care and discharge planning are shown in Table 1.7 Medicare patients readmitted to the hospital within 30 days of discharge (19.6%) cost the US healthcare system roughly $15 billion each year.8 The Agency for Healthcare Research and Quality (AHRQ) found a $412 per patient cost savings associated with patients who had a clear understanding of their hospital discharge instructions and medication use compared with patients who did not understand their instructions well.9

Reasons for Poor Discharge

The major reasons for poor discharge are system failures, inattention to the importance of medication reconciliation, lax standards, and poor information technology (IT).4 Direct communication between hospitalists and primary care physicians (PCPs) occurs in less than 20% of hospitalizations, and discharge summaries are available at less than 34% of first postdischarge visits.10 Inadequate communication between physicians, hospitalists, PCPs, and consultants also contributes to medication errors and potentially avoidable hospital readmissions.

In the past, a hospital receiving full payment despite its poor procedures for discharge had no incentive to improve. Even though The Joint Commission requires discharge summaries to be completed within 30 days, until now, no requirement existed to document pending tests. And IT vendors have had no incentive to create systems that can communicate with one another in this area. However, this scenario is changing rapidly, and hospitals will need to do what is right for patients and be prepared to comply with regulatory changes.

The Hospital’s Task

From the viewpoint of the hospital, the discharge medication process should be improved to: (1) assure that discharge prescriptions contain no errors by reconciling them with the inpatient medication orders and the patient’s prescriptions prior to admission; (2) capture all discharge prescriptions (if operating a hospital-owned ambulatory pharmacy) to improve revenue and improved outcomes; (3) educate patients on the importance of taking their medications on the schedule prescribed; and (4) reinforce with patients the importance of seeing their PCPs within 14 days of discharge. All of these actions have been shown to decrease hospital readmissions. This is a goal for which every institution is striving.

Since part of the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores are calculated based on a patient’s education on newly prescribed medication and the intensity of AEs from these medications, the hospital has added incentive to ensure its discharge process is optimal.

Medication Reconciliation

Medication reconciliation is the process of comparing a patient’s new medication orders with all the medications the patient had been taking prior to changing levels of care. These changes in levels of care occur as the patient moves through the healthcare system; from home to the emergency department (ED), from the ED to an inpatient bed, from a general medical-surgical unit to an intensive care unit (ICU) or vice versa, from the ICU to surgery, and from the hospital back to home or to an extended care facility. Care must be taken at each of these transitions to avoid drug-related errors (eg, through omission, commission, duplication).

At the time of admission to the hospital, the steps include: (1) determining precisely the medications the patient was taking at home (home meds) and how the patient was taking them (ie, dosages, frequency, compliance); (2) determining which of the previous home meds must be continued while in the hospital or at the next level of care; and (3) determining what new medications the patient needs to receive in the hospital or at the next level of care.

At discharge, the steps include: (1) determining the postdischarge medication regimen based upon previous home meds, new medications received in the hospital or next level of care, and the new going-home (discharge) medication regimen; (2) developing discharge instructions for the patient for home medications; (3) educating the patient; and (4) transmitting the medication list to the follow-up physician. Oftentimes, the problem is that this process is not standardized and there are 2 to 3 different disciplines involved in the process, resulting in inconsistency.11

A pharmacist’s input into the admission and discharge medication reconciliation process can yield substantial results. Verbal, written, or electronic contact between a hospital pharmacist and the patient’s community pharmacist is the ideal. One study discovered that medication discrepancies at discharge were disturbingly common without pharmacist reconciliation, identifi ed in 59.6% of patients.12

Implementation of a pharmacist-facilitated discharge process increased recognition and resolution of these errors. Follow-up telephone calls enabled pharmacists to reinforce discharge instructions and promoted early recognition and resolution of postdischarge medication-related problems in patients taking more than 5 medications with at least 1 high-risk medication.
