Breuker et al. (2021) demonstrate that these errors are not isolated events limited to unusual cases; instead, they occur routinely in hospitalized populations. The study shows that medication reconciliation is more than a documentation requirement. It is a fundamental patient safety intervention that depends on vigilant nursing involvement and strong interdisciplinary collaboration.

Supporting Evidence from the Literature

Jošt et al. (2024) performed a pragmatic clinical trial involving 414 adult medical patients to evaluate pharmacist-led medication reconciliation at discharge. Patients receiving the intervention experienced clinically important medication errors at a rate of only 9.3%, compared with 61.9% in the standard-care group. After statistical adjustment, the intervention reduced the odds of a clinically important error by a factor of 20. Although the study did not demonstrate a statistically significant decrease in 30-day healthcare utilization, the marked reduction in discharge errors reinforces the findings of Breuker et al. (2021) and confirms that transition-related medication errors are common yet highly responsive to systematic reconciliation.

Alghamdi et al. (2023) implemented a multicenter quality improvement project across 18 hospitals focused on standardized medication reconciliation at both admission and discharge. The initiative reduced the percentage of patients with at least one outstanding unintentional discrepancy at admission from 27% to 7% and at discharge from 17% to 5%. Documentation compliance within 24 hours also improved significantly. These findings extend Breuker et al. (2021) by showing that the problem is not confined to one setting; rather, medication discrepancies are a systems-level issue that can be meaningfully reduced through standardized workflows, measurable accountability, and interdisciplinary coordination.

Zheng et al. (2024) conducted a prospective quality improvement study of 31 high-risk internal medicine patients at discharge and identified 40 medication errors, with 68% of patients experiencing at least one error and a mean of 1.3 errors per patient. Seventy-five percent of the errors were classified as serious, and 2.5% were potentially life-threatening. Common issues included therapy duplications and medication access barriers, and pharmacist intervention was associated with an estimated cost avoidance of $24,784. This study adds an important economic and harm-prevention perspective to the problem identified by Breuker et al. (2021), demonstrating that discharge discrepancies affect both patient outcomes and organizational resources.

Taken together, the four studies reveal a consistent pattern: medication discrepancies at admission and discharge are prevalent, disproportionately affect patients with polypharmacy, and carry serious clinical and financial consequences. A further point of synthesis is that the studies align on both type and severity of risk: omissions, duplications, and other discrepancies occur most often when medication regimens are complex, and a substantial share of those discrepancies have the potential to cause meaningful harm. Importantly, the literature also shows that the problem is modifiable through structured, team-based reconciliation processes in which nurses remain essential for assessment, communication, patient education, and reinforcement of the discharge plan.

Conclusion

Medication errors and unintended discrepancies at hospital admission and discharge constitute a serious, persistent practice problem that compromises patient safety and healthcare efficiency. Breuker et al. (2021) establish the high prevalence and clinical severity of these errors, particularly omissions in patients with complex medication regimens. Supporting research by Jošt et al. (2024), Alghamdi et al. (2023), and Zheng et al. (2024) reinforces the widespread nature of the issue while showing that targeted reconciliation efforts can substantially reduce error rates. In my professional view, this problem holds particular significance for nursing because nurses maintain continuous proximity to patients and are uniquely positioned to identify discrepancies at the bedside, facilitate interdisciplinary clarification, deliver effective discharge teaching, and assess patient understanding and access to medications. This practice problem is also highly appropriate for the Knowledge-to-Action Framework because the knowledge gap is clear, the intervention is actionable, and the desired outcomes are meaningful for patients, clinicians, and healthcare organizations. Translating the evidence into a sustainable, context-specific medication reconciliation process would provide a strong basis for future implementation and evaluation work.
