A cross-sectional observational study of high override rates of drug allergy alerts in inpatient and outpatient settings, and opportunities for improvement.
Slight SP, Beeler PE, Seger DL, et al. BMJ Qual Saf. 2017;26:217-225.
Clinical decision support systems are intended to improve safety by providing clinicians with information about potential harms—principally harmful drug interactions and allergies—at the point of care. Analyzing more than 150,000 drug allergy warnings in the inpatient and outpatient settings within a single health care system, this study examined how often the warnings were overridden and the appropriateness of prescribers' reasons for doing so. Clinicians overrode 81% of warnings in hospitalized patients and 77% of alerts in outpatients. More than 96% of the overrides were judged appropriate by independent clinical reviewers. These proportions are similar to prior studies. A common appropriate reason for overriding was that the patient had actually tolerated the drug in question, leading the authors to call for improving the accuracy of allergy documentation in electronic medical records. A few classes of drugs accounted for a large proportion of overridden alerts, suggesting that enhancing the accuracy of allergy warnings for these drugs could significantly reduce the overall burden of alerts. Given that alert fatigue is an increasingly recognized patient safety hazard, creating tailored alerts could help clinical decision support systems achieve their potential to improve safety.

From physician intent to the pharmacy label: prevalence and description of discrepancies from a cross-sectional evaluation of electronic prescriptions.

One major safety advantage of computerized provider order entry (CPOE) systems lies in their ability to prevent adverse drug events due to prescribing errors. In the outpatient setting, use of electronic prescriptions is growing thanks to studies demonstrating that e-prescribing reduces medication errors. However, as with CPOE in general, increasing use of e-prescribing is leading to greater recognition of new types of errors associated with this new technology. This study analyzed the frequency of unintended discrepancies in e-prescriptions from three primary care clinics by comparing the prescription information in the prescribing physician's note with the order entered into the e-prescribing system and the medication ultimately dispensed by the pharmacy. The investigators found that errors occurred at each stage of the process, with a small but significant rate of discrepancies between both physician notes and e-prescriptions and between e-prescriptions and the medication dispensed. These errors often occurred when providers entered free-text instructions into the e-prescribing system, as found in prior research. The potential safety benefits and hazards of e-prescribing are discussed in detail in an AHRQ WebM&M commentary.
Investigating the prevalence and causes of prescribing errors in general practice: The PRACtICe Study.
Avery T, Barber N, Ghaleb M, et al. London, UK: General Medical Council; May 2, 2012.
Examining prescription errors in general practices in England, this report suggests that information technology and incident reporting could address issues that persist since an earlier study.
