Electronic Health Records, Electronic Prescribing and Medication Errors: A Systematic Review of Literature, 2000-2014

Background: The electronic prescribing system, either standalone or embedded in the electronic health record, is a powerful tool in the hands of healthcare providers, as it reduces half of medication errors caused by handwritten prescribing.
Objective: This article synthesizes the international literature on electronic health records (EHRs), e-prescribing (EP) and medication errors (MEs) and provides a platform to World Health Organization Eastern Mediterranean Region (WHO-EMR) countries for implementing EHRs and EP in healthcare system.
Methods: Computer searches of PubMed, MEDLINE, Quertle®, Google Scholar, Web Knowledge and International Pharmacy Abstract databases were conducted for the years 2000–2014 using several single- and combined-keyword strategies, with 184 articles retained for evaluation.
Results: Although e-prescribing integrated with EHR reduces medication errors at all healthcare levels, decreases morbidity and mortality, enhances patient and healthcare provider satisfaction by reducing costs and improving quality of life, it produces different types of medication errors at various stages of the prescription process. An EHR with EP that has a clinical decision support system (CDSS), dose-limit range, drug–drug interaction alert protocols, and formulary decision support helps to improve EP and ensures greater patient safety and other multiple applications.

Conclusion: EHRs with EP systems should be implemented in healthcare systems for the sake of better quality healthcare and patient safety throughout the WHO-EMR countries especially in the Kingdom of Saudi Arabia. Evidently there is limited data in these countries and hence further studies are needed to assess impact of EHRs and EP system (EPSs) on medication errors, quality of healthcare, patient safety and outcome, morbidity and mortality rates, patients’ and healthcare providers’ acceptance, and especially its cost-effectiveness.
