Svedahl ER, Pape K, Austad B, et al. BMJ Qual Saf. 2022;Epub Dec 15.
Inappropriate referrals and unnecessary hospital admissions are ongoing patient safety problems. This cohort study set in Norway examined the impact of emergency physician referral thresholds from out-of-hours services on patient outcomes.  
Kaplan HM, Birnbaum JF, Kulkarni PA. Diagnosis (Berl). 2022;9:421-429.
Premature diagnostic closure, also called anchoring bias, relies on initial diagnostic impression without continuing to explore differential diagnoses. This commentary proposes a cognitive forcing strategy of “endpoint diagnosis,” or continuing to ask “why” until additional diagnostic evaluations have been exhausted. The authors describe four common contexts when endpoint diagnoses are not pursued or reached.

The CancelRx tool is designed to improve communication between electronic health record (EHR) systems and pharmacy dispensing software. However, interoperability issues can limit the tool’s usefulness and result in inadvertent dispensing of discontinued medications. This evaluation of discontinued medications at one health systems over a one-month period found that only one-third to one-half of discontinued medications were e-prescribed using the same EHR system and would result in a CancelRx message to the pharmacy; the remainder of discontinued medications were patient-reported or reconciled from outside sources.

Electronic health records (EHR) systems frequently interact with EHRs in other organizations, between clinical settings (e.g., in-patient and out-patient), or with devices (e.g., smart pumps). In this review, 12 studies were identified that examined the effect of EHR interoperability on patient safety. While EHR interoperability was shown to improve patient safety, outcome measure heterogeneity limits measuring true effects.

Patient safety algorithms developed through research must also be implemented into clinical practice. This article describes the process of translating an electronic health record-based algorithm for detecting missed follow-up of colorectal or lung cancer testing, from research into practice. All 12 test sites were able to successfully implement the trigger and identify appropriate cases.

Wrong blood in tube (WBIT) errors can result in serious diagnostic and treatment errors, but may go unrecognized by clinical staff. In this study, machine learning was used to identify potential WBIT errors which were then compared to manual review by laboratory staff. The machine learning models showed higher accuracy, sensitivity, and specificity compared to manual review. 
Webster KLW, Keebler JR, Lazzara EH, et al. Jt Comm Qual Patient Saf. 2022;48:343-353.
Effective handoff communication is a key indicator of safe patient care. These authors outline a new model for handoff communication, integrating three theoretical frameworks addressing relevant inputs (i.e., individual organizational, environmental factors), mediators (e.g., communication, leadership), outcomes (e.g., patient, provider, teamwork, and organizational outcomes), and adaptation loops.
Buitrago I, Seidl KL, Gingold DB, et al. J Healthc Qual. 2022;44:169-177.
Reducing hospital 30-day readmissions is seen as a way to improve safety and reduce costs. Baltimore City mobile integrated health and community paramedicine (MIH-CP) was designed to improve transitional care from hospital to home. After one year in operation, MIH-CP performed a chart review to determine causes of readmission among patients in the program. Root cause analysis indicated that at least one social determinant of health (e.g., health literacy) played a role in preventable readmissions; the program was modified to improve transitional care.
Frisch NK, Gibson PC, Stowman AM, et al. Am J Emerg Med. 2022;158:18-26.
Electronic health records (EHR) can improve patient care and safety but are not without potential risks. A cyberattack led to a 25-day shutdown of a hospital’s EHR that necessitated a rapid shift to manual processes. This article outlines the laboratory service’s processes during the shutdown, including patient safety and error reduction, billing, and maintaining compliance with regulatory policies.
Blijleven V, Hoxha F, Jaspers MWM. J Med Internet Res. 2022;24:e33046.
Electronic health record (EHR) workarounds arise when users bypass safety features to increase efficiency. This scoping review aimed to validate, refine, and enrich the Sociotechnical EHR Workaround Analysis (SEWA) framework. Multidisciplinary teams (e.g. leadership, providers, EHR developers) can now use the refined SEWA framework to identify, analyze and resolve unsafe workarounds, leading to improved quality and efficiency of care.

Failure to follow up on abnormal diagnostic test results can cause delays in patients receiving appropriate care. This hospital used an artificial intelligence natural language processing system to identify radiology reports requiring follow-up. The system triggered automated notifications to the patient and ordering provider, and tracked follow-ups to completion. System development, deployment and next steps are detailed.
Rajan SS, Baldwin JL, Giardina TD, et al. J Patient Saf. 2022;18:e262-e266.
Radiofrequency identification (RFID) technology has been most commonly used in perioperative settings to improve patient safety. This study explored whether RFID technology can improve process measures in laboratory settings, such as order tracking, specimen processing, and test result communication. Findings indicate that RFID-tracked orders were more likely to have completed testing process milestones and were completed more quickly.
Lafferty M, Harrod M, Krein SL, et al. J Am Med Inform Assoc. 2021;28:28(12).
Use of one-way communication technologies, such as pagers, in hospitals have led to workarounds to improve communication. Through observation, shadowing, interviews, and focus groups with nurses and physicians, this study describes antecedents, types, and effects of workarounds and their potential impact on patient safety.

Ensuring maternal safety is a patient safety priority. This library reflects a curated selection of PSNet content focused on improving maternal safety. Included resources explore strategies with the potential to improve maternal care delivery and outcomes, such as high reliability, collaborative initiatives, teamwork, and trigger tools.
McHugh MD, Aiken LH, Sloane DM, et al. The Lancet. 2021;397:1905-1913.
While research shows that better nurse staffing ratios are associated with improved patient outcomes, policies setting minimum nurse-to-patient ratios in hospitals are rarely implemented. In 2016, select Queensland (Australia) hospitals implemented minimum nurse staffing ratios. Compared to hospitals that did not implement minimum nurse staffing ratios, length of stay, mortality, and readmission rates were significantly lower in intervention hospitals, providing evidence, once again, that minimum staffing ratios can improve patient outcomes.

Electronic health record (EHR) downtime can disrupt patient care and increase risk for medical errors. Semi-structured interviews with healthcare staff and leadership at one large hospital in England illustrate the negative consequences of a three-week downtime of an electronic pathology system on patient experience and safety. The authors propose recommendations for hospitals to consider when preparing for potential technology downtimes.
Massa S, Wu J, Wang C, et al. Jt Comm J Qual Patient Saf. 2021;47:242-249.
The objective of this mixed methods study was to characterize training, practices, and preferences in interprofessional handoffs from the operating room to the intensive care unit (OR-to-ICU). Anesthesia residents, registered nurses, and advanced practice providers indicated that they had not received enough preparation for OR-to-ICU handoffs in their clinical education or on-the-job training. Clinicians from all professions noted a high value of interprofessional education in OR-to-ICU handoffs, especially during early degree programs would be beneficial.
Rich RK, Jimenez FE, Puumala SE, et al. HERD. 2020;14:65-82.
Design changes in health care settings can improve patient safety. In this single-site study, researchers found that new hospital design elements (single patient acuity-adaptable rooms, decentralized nursing stations, access to nature, etc.) improved patient satisfaction but did not impact patient outcomes such as length, falls, medication events, or healthcare-associated infections.  
Ihlebæk HM. Int J Nurs Stud. 2020;109:103636.
Using ethnographic methods, this study explored the impact of ‘silent report’ (computer-mediated handover) on nurses’ cognitive work and communication. The authors summarize four emerging themes, which highlight and characterize the importance of oral communication to ensure accurate and useful handovers.
