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.

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.

This quarterly commentary explores a wide range of subjects associated with patient safety, such as the impact of disruptive behavior on teams, the value of apologies, and safety challenges due to COVID-19. Older materials are available online for free.

Air medical transport carries unique patient safety risks. In this study, researchers used simulation training and healthcare failure mode and effect analysis (HFMEA) to identify latent safety threats related to patient transport via helicopter. This approach identified 31 latent safety threats (18 were deemed critical) related to care coordination, facilities, equipment, and devices.

Incident reporting systems are used to detect patient safety concerns and determine potential causes and opportunities for improvements. In the perioperative setting of one hospital, insufficient handoffs were the most common event type in the “coordination of care” category. Use of structured handoffs is recommended to improve communication and patient safety.

Patient misidentification errors are common and potentially catastrophic. Patient identification incidents reported in one hospital were examined to identify errors and contributory factors. Of the 293 reported incidents, the most common errors were missing wristbands, wrong charts or notes in files, administrative issues, and wrong labeling. The most frequent contributory factors include absence of patient identity control, patient transfer, and emergency context.

Autopsies are an important tool for identifying diagnostic errors. This retrospective study of 821 pediatric cancer deaths found that 10% had a major diagnostic discrepancy between antemortem and postmortem diagnoses. These discrepancies primarily consisted of missed infections, missed cancer diagnoses, and organ complications.

High reliability organizations encourage staff to self-report errors and hazards for comprehensive review and improvement. Three hospitals in one health system implemented a voluntary error reporting system for clinicians to report their own and others’ clinical errors. Although only 5% of reported errors were physician self-reports, there were still benefits: it captured novel errors, provided a safe space to report those errors, and encouraged secondary insights into causes of the errors.

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.

Patients who have fallen in their homes and are found by a home healthcare worker are referred to as “found-on-floor” incidents. This study found that length of stay was a key theme in found-on-floor incidents and signaled underlying system-level issues, such as lack of informational continuity across the continuum of care (e.g., lack of standard documentation across settings, unclear messaging regarding clients’ home care needs), reliance on home healthcare workers instead of rehabilitation professionals, and lack of fall assessment follow-up. The authors recommend systems-level changes to improve fall prevention practices, such as use of electronic health records across the continuum of care and enhanced accountability in home safety.

Patient safety in primary care is an emerging focus. This cross-sectional study across primary care clinics in England explored the main factors contributing to patient-reported harm experiences. Factors included incidents related to communication, care coordination, and incorrect or delayed; diagnosis and/or treatment.

Providing patients access to their medical records can improve patient engagement and error identification. A survey of patients and families found that about half of adult patients and pediatric families who perceived a serious mistake in their ambulatory care notes reported it, but identified several barriers to reporting (e.g. no clear reporting mechanism, lack of perceived support).

This study surveyed 9,206 adults across the United States about their perceptions of medical errors occurring in ambulatory care settings. Thirty-six percent of respondents perceived that their doctor has ever made a mistake, provided an incorrect diagnosis, or given an incorrect (or delayed) treatment. According to these findings, patient-perceived medical errors and harms occurred most commonly in women and those in poor health with comorbid conditions.

Lack of timely follow-up of test results is a recognized patient safety problem in primary care and can lead to missed or delayed diagnoses. This study used human factors methods to understand lack of timely follow-up of abnormal test results in outpatient settings. Through interviews with the ordering physicians, the researchers identified several contributing factors, such as provider-patient communication channel mismatch and diffusion of responsibility.

The author defines ‘work debate spaces’ as organizational spaces that serve as a vehicle for organizational learning, practice changes, and performance improvement. This article discusses the role of formal and informal ‘work debate spaces’ in establishing a culture of safety in critical care settings. Examples of formal and informal spaces include mortality and morbidity (M&M) meetings (formal) and handoffs between shifts (informal).

This study used a trigger tool to retrospectively identify and characterize no-harm incidents affecting adult patients in home healthcare settings in Sweden. The most common incidents identified by the trigger tool were falls without injury, medication management incidents, and moderate pain. Common contributing factors included delayed, erroneous, or incomplete nursing care and treatment.

Diagnostic errors, including missed diagnoses of adolescent depression, elevated blood pressure, and delayed response to abnormal lab results, are common in pediatric primary care. Building upon previous work, this study used root cause analyses to identify the failure points and contributing factors to these errors. Omitted process steps included failure to screen for adolescent depression, failure to recognize and act on abnormal blood pressure values, and failure to notify families of abnormal lab results. Factors contributing most commonly to these errors were patient volume, inadequate staffing, clinic environment, electronic and written communication, and provider knowledge.

This scoping review assessed 44 studies to describe the scope of the evidence of the impact of missed, rationed and unfinished nursing care on patient-related outcomes; 9 of these studies focused on the impact on patient safety outcomes. The review concludes that medication errors as the biggest threat to patient safety resulting from missed, rationed or unfinished care, and that falls (with or without injury) and hospital-acquired infections are the most common resulting adverse events. These adverse events are attributed to the omission of preventive nursing care activities, such as handwashing, patient education and maintaining a safe environment.

Retained surgical items (RSI) are considered ‘never events’ but continue to occur. In this study, researchers compared the RSI rate in Veterans Health (VA) surgery programs with (n=46) and without (n=91) surgical count technology and analyzed the resulting root cause analyses (RCA) for these events. The RSI rate was significantly higher in for the programs with surgical count technology compared to the programs without (1/18,221 vs. 1/30,593). Analysis of RCAs found the majority of incidents (64%) involved human factors issues (e.g., staffing changes during shifts, staff fatigue), policy/procedure failures (e.g., failure to perform methodical wound sweep) or communication errors.
