Use of a perceived efficacy tool to evaluate the FallTIPS program.
The authors assessed nurses' opinions of the efficacy of using the FallTIPS (Tailoring Interventions for Patient Safety) fall prevention program. They found that the nurses who used FallTIPS perceived that efficiencies in patient care compensated for the time spent on FallTIPS. Nurses valued the program, and findings confirmed the importance of patient and family engagement with staff in the fall prevention process.

Use of patient complaints to identify diagnosis-related safety concerns: a mixed-method evaluation.
This retrospective cohort study evaluated the use of patient complaint data to identify patient safety concerns related to diagnosis as an initial step to using this information to facilitate learning and improvement. Patient complaints submitted to the Geisinger healthcare system were reviewed with 2 cohorts from August to December 2017 (cohort 1) and January to June 2018 (cohort 2). The authors selected complaints more likely to be associated with diagnostic concerns in Geisinger’s existing complaint taxonomy. In cohort 1, 1865 complaint summaries were reviewed and 177 (9.5%) were identified as concerning. The review identified 39 diagnostic errors. In cohort 2, 2423 patient complaints were reviewed and 310 (12.8%) concerning reports were identified. A 10% sample contained give diagnostic errors. Most errors were categorized as “Clinical Care” issues.

A shared decision-making tool for drug interactions between warfarin and nonsteroidal anti-inflammatory drugs: design and usability study.
Exposure to life-threatening drug-drug interactions (DDIs) occurs despite the widespread use of clinical decision support. The DDI between warfarin and nonsteroidal anti-inflammatory drugs is common and potentially life-threatening. Patients can play a substantial role in preventing harm from DDIs; however, the current model for DDI decision-making is clinician centric. This study aimed to design and examine the usability of DDInteract, a tool to support shared decision-making (SDM) between a patient and provider for the DDI between warfarin and nonsteroidal anti-inflammatory drugs.

Natural language processing for the surveillance of postoperative venous thromboembolism.
The objective of the study was to develop a portal natural language processing approach to aid in the identification of postoperative venous thromboembolism events from free-text clinical notes. The investigators concluded that accurate surveillance of postoperative venous thromboembolism may be achieved using natural language processing on clinical notes in 2 independent health care systems. They indicated that these findings suggest natural language processing may augment manual chart abstraction for large registries such as National Surgical Quality Improvement Program.

The association of nursing home characteristics and quality with adverse events after a hospitalization.
This prospective cohort analysis measured the association of long-stay nursing home residents returning to the facility after a hospitalization and adverse events (AEs). Thirty-two nursing homes in New England states participated with a total of 555 long-stay residents contributing 762 returns from hospitalizations. The authors measured the association between AEs developing in the 45 days following discharge back to long-term care and characteristics of the nursing homes including bed size, ownership, 5-star quality ratings, registered nurse and nursing assistant hours, and the individual Centers for Medicare & Medicaid Services (CMS) quality indicators. They found no association of AEs with most nursing home characteristics. Several individual quality indicators were associated with AEs. The highest tertile of residents with depression had a hazard ratio (HR) of 1.65 and the highest tertile of the percentage taking antipsychotic medications had an HR of 1.58. Residents needing increased assistance with activities of daily living was statistically significant, but not monotonic.

Time trends in patient characteristics and in-hospital adverse events for primary total knee arthroplasty in the United States: 2010-2017.
This study looked at trends in patient characteristics and in-hospital adverse events (AEs) for primary total knee arthroplasty (TKA) from 2010 to 2017. A total of 14,057 primary TKAs captured by the Medicare Patient Safety Monitoring System was retrospectively reviewed. Risk factors that increased included obesity prevalence, tobacco smoking, and renal disease. There were reductions in coronary artery disease and chronic warfarin use. Inpatient AEs decreased from 4.9% to 2.5%, primarily driven by reductions in anticoagulant-associated AEs, including major bleeding and hematomas, catheter-associated urinary tract infections, pressure ulcers, and venous thromboembolism.

Relative risks of adverse events among older adults receiving opioids versus NSAIDs after hospital discharge: a nationwide cohort study.
This retrospective cohort study’s objective was to determine the incidence and risk of post-discharge adverse events among opioid claims in the week after hospital discharge, compared to those with nonsteroidal anti-inflammatory drugs (NSAIDs) claims alone. A national sample of Medicare beneficiaries age 65 and older who were hospitalized in the United States in 2016 was used. Beneficiaries who were admitted from or discharged to a facility were excluded. The authors used 3:1 propensity matching to match beneficiaries with an opioid claim in the week after discharge (13,385) with beneficiaries with NSAID claim alone (4,677). Beneficiaries receiving opioids had a higher incidence of death, healthcare utilization, and any potential adverse effect compared to those with an NSAID claim only. Specific adverse effects included higher relative risk of fall/fracture, nausea/vomiting, and slowed colonic motility.

Validation of an electronic trigger to measure missed diagnosis of stroke in emergency departments.
Diagnostic errors are major contributors to preventable patient harm. In this study, the investigators validated the use of an electronic health record (EHR)-based trigger (e-trigger) to measure missed opportunities in stroke diagnosis in emergency departments (EDs). The investigators concluded that a symptom-disease pair-based e-trigger identified missed diagnoses of stroke with a modest positive predictive value, underscoring the need for chart review validation procedures to identify diagnostic errors in large data sets.

Risk of in-hospital falls among medications commonly used for insomnia in hospitalized patients.
This study investigated the risk of in-hospital falls among patients receiving medications commonly used for insomnia. This retrospective cohort study was conducted at a large academic medical center from January 2007 to July 2013. Adults admitted for a primary psychiatric disorder were excluded. Medications of interest included benzodiazepines, non-benzodiazepine benzodiazepine receptor agonists, trazodone, atypical antipsychotics, and diphenhydramine. Among 225,498 hospitalizations, 37.7% had exposure to at least one of the medication classes of interest with benzodiazepines being the most commonly prescribed. A fall occurred in 1.1% (2,427) of hospitalizations. The rate of falls per 1,000 hospital days was greater among patients with exposure to each of the medications of interest compared to unexposed patients.

Administrative data are unreliable for ranking hospital performance based on serious complications after spine fusion.
The authors evaluated the extent to which a metric of serious complications determined from administrative data can reliably profile hospital performance in spine fusion surgery. They found that a metric of serious complications was unreliable for benchmarking cervical fusion outcomes and only modestly reliable for thoracolumbar fusion. They concluded that, when assessed using administrative datasets, these measures appeared to be inappropriate for high-stakes applications, such as public reporting or pay-for-performance.

Prenatal exposure to general anesthesia and childhood behavioral deficit.
This study looked at the association of prenatal exposure to general anesthesia and childhood behavioral deficits. The Raine Study was an observational cohort study of children born in Perth, Western Australia with 2 generations of participations. The first generation (Gen1) were mothers enrolled during pregnancy, and the second generation (Gen2) were the children born from 1989 to 1992 with neuropsychological and behavioral tests evaluated at age 10. Six neuropsychological and behavioral tests were used with the Child Behavior Checklist (CBCL) as the main test. Among 2024 children with available outcome scores, 22 were prenatally exposed to general anesthesia. These children had higher CBCL Externalizing behavioral scores than unexposed children. Of the six tests used, only CBCL Externalizing behavioral scores remained significant after multiple comparisons adjustment.

Diagnostic errors in pediatric critical care: a systematic review.
This study is a systematic review on the prevalence, impact, and contributing factors related to diagnostic errors in the PICU. A database search was done for literature up through December 2019. Using specific criteria, 396 abstracts were screened, and 17 studies were included. Fifteen of 17 studies had an observational research design. Autopsy studies showed a 10-23% rate of missed major diagnosis with 5-16% of the errors having a potential adverse impact on survival and would have changed care management. Retrospective record review studies reported varying rates of diagnostic error from 8% in a general PICU population to 12% among unexpected critical admissions. About a quarter of those patients were discussed at PICU morbidity and mortality conferences. Most misdiagnosed conditions were cardiovascular, infectious, congenital, or neurologic. System, cognitive, and both system and cognitive factors were associated with diagnostic error but there is limited information on the impact of misdiagnosis.

DDIWAS: high-throughput electronic health record-based screening of drug-drug interactions.
In this study, the investigators developed and evaluated Drug-Drug Interaction Wide Association Study (DDIWAS). This novel method detected potential drug-drug interactions (DDIs) by leveraging data from the electronic health record (EHR) allergy list. The investigators concluded that they demonstrated the value of incorporating information mined from existing allergy lists to detect DDIs in a real-world clinical setting. They indicate that since allergy lists are routinely collected in EHRs, DDIWAS has the potential to detect and validate DDI signals across institutions.

Predicting self-intercepted medication ordering errors using machine learning.
Current approaches to understanding medication ordering errors rely on relatively small manually captured error samples. These approaches are resource-intensive, do not scale for computerized provider order entry (CPOE) systems, and are likely to miss important risk factors associated with medication ordering errors. Previously, the investigators described a dataset of CPOE-based medication voiding accompanied by univariable and multivariable regression analyses. In this paper, they updated the analysis using machine learning (ML) models to predict erroneous medication orders and identify its contributing factors.

Association between emergency department chief complaint and adverse hospitalization outcomes: a simple early warning system?
Researchers sought to examine the association between the emergency department chief complaint and specific adverse outcomes after admission to a general medicine floor. They found that chief complaint may be an early identifier of those patients uniquely at risk for adverse hospitalization outcomes. Patients presenting with seizure, leg swelling, and shortness of breath who were subsequently admitted to a general medical floor were more likely to suffer care escalations, Rapid Response Team activation, or mortality. Conversely, patients with chief complaints of loss of consciousness, headache, and chest pain were at low risk of adverse outcomes.
