The AHRQ PSNet Collection comprises an extensive selection of resources relevant to the patient safety community. These resources come in a variety of formats, including literature, research, tools, and Web sites. Resources are identified using the National Library of Medicine’s Medline database, various news and content aggregators, and the expertise of the AHRQ PSNet editorial and technical teams.
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.
Delays in diagnosis and treatment during after-hours care pose serious threats to patient safety. This case-control study compared missed acute coronary syndrome (ACS) cases to other cases with chest discomfort occurring during out-of-hours services in primary care. Predictors of missed ACS included the use of cardiovascular medication, non-retrosternal chest pain, and consultation of the supervising general practitioner.
This Primer provides an overview of the history and current status of the patient safety field and key definitions and concepts. It links to other Patient Safety Primers that discuss the concepts in more detail.

Care transitions and handoffs represent a vulnerable time for patients, as failure to communicate important clinical information may occur with the potential for harm. In this pre–post study, researchers found that implementation of an electronic health record tool designed to improve the handoff between oncology clinic and infusion nurses was associated with a reduction in medication errors, shorter average patient waiting time, and better communication between nurses.

Prior research has shown that when patients have access to clinicians' notes, they may identify relevant safety concerns. In this study, 9550 obstetrics and gynecology patients were provided with access to their outpatient visit documentation. Almost 70% of eligible patients read one or more notes during the study period, but only 3.2% shared feedback through 232 electronic reports. Of patients who provided feedback, 27% identified errors in the documentation; provider reviewers determined that 75% of these could impact care.

Failure to follow up abnormal test results can lead to a delayed or missed diagnosis. Using data from a single institution, researchers observed that while more than 99% of abnormal mammograms received appropriate follow-up, only 91% of abnormal Papanicolaou (Pap) smears did. They suggest that improving workflow processes and ensuring appropriate use of health information technology can help optimize test result follow-up.

Trigger tools facilitate identification of adverse events. In this retrospective medical record review study, investigators found that an automated trigger successfully identified delayed follow-up of laboratory thyroid testing among patients with hypothyroidism, with a positive predictive value of 60%. The authors suggest that this trigger approach could be used to detect and ameliorate follow-up delays in real time.

Failure to follow-up on test results in ambulatory practice is a common, serious safety concern. This study examined the use of a results manager tool by primary care physicians in Partners Healthcare in Boston. Although the vast majority of providers used the tool, many did not find that it was helpful for any specific purpose and only 64% were satisfied with the tool.
A teenager presented to an urgent care clinic with new bumps and white spots near her tongue. Although she was diagnosed with herpetic gingivostomatitis, the after-visit summary incorrectly populated the diagnosis of "thrush" from the triage information, which was not updated with the correct diagnosis. The mistake on the printout caused confusion for the patient's mother and necessitated several follow-up communications to clear up.

Although electronic test ordering resulted in fewer patient identification errors in a clinical laboratory, significant variability in error rates between centers remained, emphasizing the continued effect of human behavior on interventions.

Appropriate follow-up of abnormal test results remains a difficult issue. This local task force report recommends standardization of notification policies, clear identification of the care team, enhanced electronic result tracking, and quality reporting and metrics.
An elderly man presented to an emergency department (ED) with new onset chest pain. In reviewing the patient's electronic medical record (EMR), the ED physician noted a history of "PE," but the patient denied ever having a pulmonary embolus. Further investigation in the EMR revealed that, many years earlier, the abbreviation was intended to stand for "physical examination." Someone had mistakenly copied and pasted PE under past medical history, and the error was carried forward for years.
A healthy elderly man presented to his primary care doctor—a third-year internal medicine resident—for routine examination. A PSA test was markedly elevated, but the results came back after the resident had graduated, and the alert went unread. Months later, the patient presented with new onset low back pain and was diagnosed with metastatic prostate cancer.
Introduction of an electronic discharge summary was associated with more timely communication with outpatient physicians and improved communication of potential patient safety problems, such as test results that were pending at the time of discharge.
Most patient interactions with the health care system occur in the outpatient setting. Many potential and actual safety problems occur there as well.(1) Yet patient safety literature and practice do not seem to have reached deeply into ambulatory care.
Four months after surgery, a woman with osteosarcoma receiving outpatient chemotherapy was admitted for possible cellulitis. Discharged home on methotrexate and antibiotics, the patient developed methotrexate toxicity, partly due to a drug interaction.
An elderly, non–English-speaking man with diabetes was admitted to the hospital twice in 8 days due to hypoglycemia. At discharge, the patient was instructed not to take any antidiabetic medications. In between hospitalizations, he saw his primary care physician, who restarted an antidiabetic medication.
A patient presenting to the ED with chest pain was ruled out for MI, and discharged on an ACE inhibitor. Two weeks later, he returns with a critically elevated potassium level, has a cardiac arrest, and dies.
