Gastric acid suppression therapy and its association with peritoneal dialysis-associated peritonitis in the Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS).
This study’s goal was to determine whether gastric acid suppression (GAS) (proton pump inhibitor (PPI) or histamine-2 receptor antagonists (H2RA)) use was associated with all-cause and organism-specific peritonitis in peritoneal dialysis (PD) patients. The authors used data from the Peritoneal Dialysis Outcomes and Practice Patterns Study (595 facilities, 8 countries, years 2014-2022), and associations between GAS use and time to first episode of all-cause peritonitis was examined. Out of a total of 23,797 baseline study patients, 6020 (25.3%) used PPIs, and 1382 (5.8%) used H2RAs. Overall risks of GAS use and peritonitis risk [adjusted hazard ratio (AHR)=1.05), and use of PPI (AHR 1.06) or H2RA (AHR 1.02) did not reach statistical significance. In organism-specific analyses, GAS users displayed higher peritonitis risks for gram-negative (AHR 1.29), gram-positive (AHR 1.15), culture-negative (AHR 1.20), enteric (AHR 1.23), and particularly Streptococcal (AHR 1.47) peritonitis episodes. GAS was also associated with higher overall mortality (AHR 1.13).

Emergency department utilization for pediatric gastrostomy tubes across the United States.
This study investigated the number and nature of emergency department (ED) visits to community hospitals for pediatric gastrostomy tube complication. The authors used the 2019 Nationwide Emergency Department Sample to perform a retrospective cross-sectional analysis of pediatric patients (<18 y) with a primary diagnosis of gastrostomy tube complication. Their primary outcome was a potentially preventable ED visit, defined as an encounter that did not result in any imaging, procedures, or an inpatient admission. They observed 32,036 ED visits at 535 hospitals and 15,165 (47.3%) were potentially preventable. Median age was 2 years, and 17,707 (55%) were male. Compared to White patients, patients with higher odds of potentially preventable visits were Black and Hispanic. Patients with residential zip codes in the first, second, and third median household income quartiles had higher odds of potentially preventable visits compared to the highest.

Diagnostic errors in hospitalized adults who died or were transferred to intensive care.
The objective of this retrospective cohort study was to determine the prevalence, underlying causes, and harms of diagnostic errors in hospitalized adults who were transferred to an intensive care unit or who died. Data was taken from 29 academic medical centers in the U.S. in a random sample of adults hospitalized with general medical conditions. Errors were found to have contributed to temporary harm, permanent harm, or death in nearly 18% of patients; among patients who died, diagnostic error was judged to have contributed to death in 6.6% of cases. The researchers noted that problems with choosing and interpreting tests and the processes involved with clinician assessment were a high priority for improvement efforts.

Identifying and classifying diagnostic errors in acute care across hospitals: early lessons from the Utility of Predictive Systems in Diagnostic Errors (UPSIDE) study.
This paper describes the Utility of Predictive Systems in Diagnostic Errors (UPSIDE) study, whose aim was to define the prevalence and underlying causes of diagnostic errors (DEs) in patients who die in the hospital or are transferred to the intensive care unit (ICU) after the first 48 hours. This study was conducted at 31 hospitals with more than 2500 cases reviewed using electronic health records. The authors identified some insights into key requirements into building a robust DE surveillance program by developing these steps: 1) Develop a shared understanding of what constitutes a diagnostic error; 2) Use validated tools to identify diagnostic errors and classify process failures, but respect your context; 3) Develop a standard approach to using electronic health records for case reviews; 4) Ensure reliability and consistency of the case review process; and 5) Link diagnostic error case reviews to institutional safety programs. They also developed steps to establish a diagnosis error review process at the hospital level with six processes.

Ketamine use in the intubation of critically ill children with neurological indications: a multicenter retrospective analysis.
This study examined use of ketamine in children undergoing tubal intubation (TI) for a primary neurological indication. The authors conducted a retrospective observational cohort study of critically ill children undergoing TI for neurological indications in 53 international pediatric intensive care units and emergency departments. They screened all intubations from 2014 to 2020 entered into the multicenter National Emergency Airway Registry for Children (NEAR4KIDS) registry database. Of 21,562 TIs, 2,073 were performed for a primary neurological indication, including 190 for traumatic brain injury/trauma. Patients received ketamine in 495 TIs (23.9%), which increased from 10% in 2014 to 41% in 2020. Criteria for ketamine use includes a coindication of respiratory failure, difficult airway history, and use of vagolytic agents, apneic oxygenation, and video laryngoscopy. Composite adverse outcomes were reported in 289 (13.9%) TIs and were more common in the ketamine group (17.0% vs. 13.0%). After adjusting for location, patient age and co-diagnoses, the presence of respiratory failure and shock, difficult airway history, provider demographics, intubating device, and the use of apneic oxygenation, vagolytic agents, and neuromuscular blockade, ketamine use was not significantly associated with increased composite adverse outcomes. This paucity of association remained even when only neurotrauma intubations were considered (10.6% vs. 7.7%).

Validation of measures for perioperative urinary catheter use, urinary retention, and urinary catheter-related trauma in surgical patients.
This article described a retrospective cohort study to analyze the effects of non-infectious urinary catheter-related complications, such as measurements of indwelling urinary catheter overuse, catheter-related trauma, and urinary retention. Participants were 200 patients who were undergoing general surgery operations; 65% had an indwelling urinary catheter placed at the time of surgery, 16% had urinary retention, and 6% had urinary trauma. The authors concluded that this study suggests a persistent high rate of catheter use, significant rates of urinary retention and trauma, and variation in the management of retention.

Burden of serious harms from diagnostic error in the USA.
Americans who experience serious harm from misdiagnosis annually. Serious harm is defined as permanent morbidity or morality. This cross-sectional analysis used nationally representative observational data. The authors estimated annual incident vascular events and infections from 21.5 million (M) sampled US hospital discharges (2012-2014). US-based cancer registries were used to find annual new cancers. They derived diagnostic errors and serious harms by multiplying by literature-based rates for disease-specific incidences for 15 major vascular events, infections and cancers ('Big Three' categories). Extrapolating to all diseases (including non-'Big Three' dangerous disease categories), they estimated total serious harms annually in the USA to be 795,000 (plausible range 598,000-1,023,000). Using more conservative assumptions they estimated 549,000 serious harms. These results were compatible with setting-specific serious harm estimates from inpatient, emergency department and ambulatory care. Fifteen dangerous diseases accounted for 50.7% of total serious harms and the top 5 (stroke, sepsis, pneumonia, venous thromboembolism and lung cancer) accounted for 38.7%.

Health literacy-informed communication to reduce discharge medication errors in hospitalized children: a randomized clinical trial.
This study’s objective was to test a health literacy-informed communication intervention to decrease liquid medication dosing errors compared with standard counseling in hospitalized children. This parallel, randomized clinical trial was conducted from June 22, 2021, to August 20, 2022, at a tertiary care, US children's hospital. English- and Spanish-speaking caregivers of hospitalized children 6 years or younger prescribed a new, scheduled liquid medication at discharge were included in the analysis. Observed dosing errors were the main outcome measured, and secondary outcomes included caregiver-reported medication knowledge. Among 198 randomized caregivers (mean age 31.4 years; 186 women [93.9%]; 36 [18.2%] Hispanic or Latino and 158 [79.8%] White), the primary outcome was available for 151 (76.3%). The observed mean (SD) percentage dosing error was 1.0% (2.2 percentage points) among the intervention group and 3.3% (5.1 percentage points) among the standard counseling group (absolute difference, 2.3 percentage points). Twenty-four of 79 caregivers in the intervention group (30.4%) measured an incorrect dose compared with 39 of 72 (54.2%) in the standard counseling group. The intervention enhanced caregiver-reported medication knowledge compared with the standard counseling group for medication dose (71 of 76 [93.4%] vs 55 of 69 [79.7%]), duration of administration (65 of 76 [85.5%] vs 49 of 69 [71.0%], and correct reporting of 2 or more medication adverse effects (60 of 76 [78.9%] vs 13 of 69 [18.8%]).

Medication safety event reporting: Factors that contribute to safety events during times of organizational stress.
This study’s objective was to understand the insights conveyed in hospital incident reports about how work system factors affected medication safety during a coronavirus disease-2019 (COVID-19) surge. The authors randomly selected 100 medication safety incident reports from an academic medical center (December 2020 to January 2021), identified near misses and errors, and classified contributing work system factors using the Human Factors Analysis and Classification System-Healthcare. Results showed that among 35 near misses/errors, incident reports described contributing factors (mean 1.3/report) involving skill-based errors (n = 20), communication (n = 8), and tools/technology (n = 4). Seven of these events were linked to COVID-19.

Major drug-drug interaction exposure among Medicaid-insured children in the outpatient setting.
This study’s objective was to determine the prevalence of major drug-drug interactions (DDI) exposure and factors associated with higher DDI exposure rates among children in an outpatient setting. The authors performed a cross-sectional study of children aged 0 to 18 years with ≥1 ambulatory encounter, and ≥2 dispensed outpatient prescriptions using the 2019 Marketscan Medicaid database. Primary outcomes were the prevalence and rate of major DDI exposure. Out of 781,019 children with ≥2 medication exposures, 21.4% experienced ≥1 major DDI exposure. The odds of exposure increased with age and with medical and mental health complexity. Frequently mentioned drugs included Clonidine, psychiatric medications, and asthma medications. The highest adverse physiologic effect exposure rate per 100 children included: increased drug concentrations (14.6), central nervous system depression (13.6), and heart rate-corrected QT interval prolongation (9.9).

Drug-drug interaction between dexamethasone and direct-acting oral anticoagulants: a nested case-control study in the national COVID cohort collaborative (N3C).
This study examined whether there is an association between thromboembolotic events (TEEs) and concomitant use of dexamethasone with either apixaban or rivaroxaban (both direct oral anticoagulants or DOACs) during treatment for COVID-19. The authors used data from the National COVID Cohort Collaborative (N3C) to conduct a nested case-control study. Eligible participants were adults over 18 years who were exposed to a DOAC for 10 or more consecutive days and exposure to dexamethasone at least 5 or more consecutive days. The study did not find a discernible association of TEE in patients concomitantly exposed to dexamethasone and a DOAC.

Colchicine and macrolides: a cohort study of the risk of adverse outcomes associated with concomitant exposure.
The authors conducted a cohort study using electronic health records comparing encounters with colchicine plus a macrolide and colchicine with an antibiotic non-macrolide, then assessed the relationship between the two groups. They found that heart failure was more frequent in the colchicine plus a macrolide cohort and that there was also a higher mortality rate. As there is a significant increase in the risk of hepatic failure and mortality when colchicine is concomitantly administered with a macrolide, they concluded that colchicine should not be used concomitantly with these antibiotics or should be temporarily discontinued to avoid toxic levels of colchicine.

Defining diagnostic error: a scoping review to assess the impact of the National Academies' report improving diagnosis in Health Care.
This study looked at peer-reviewed published literature to explore how researchers operationalize the National Academies of Science, Engineering, and Medicine’s (NASEM) definition of diagnostic error that was defined in their 2015 publication “Improving Diagnosis in Health Care”. Published literature was identified from October 2015 to February 2021. The authors also conducted subject matter expert interviews. Of the 34 studies identified, 16 were analyzed and abstracted to determine how diagnostic error was operationalized and measured. Studies were grouped by four themes: epidemiology, patient focus, measurement/surveillance, and clinician focus. Nine studies identified used the NASM definition. Five of those studies also operationalized with existing definitions proposed before the NASEM report, four operationalized the components of the NASEM definition, and three studies operationalized error using existing definitions only. Subject matter experts concluded that the NASEM definition functions as a foundation for researchers to conceptualize diagnostic error.

The MI-PICC Score: a risk-Prediction Model for PICC-associated Complications in the ICU.
The authors examined predictive factors for adverse events in critically ill patients with peripherally inserted central catheters (PICCs). They found that PICC-related complications in the ICU were significantly associated with history of deep vein thrombosis, active diagnosis of cancer, presence of a second central venous catheter, blood transfusion through the PICC, and PICC dwell time.

Adverse maternal and delivery outcomes in children and very young (age ≤13 years) US adolescents compared with older adolescents and adults.
This study compared adverse maternal and delivery outcomes of pregnant 10- to 13-year-olds vs 14- to 17-year-olds and 18- to 19-year-olds. This cross-sectional study looked at all patients aged 10 to 19 years who delivered at hospitals in the Premier Healthcare Database from January 2019 through May 2021. The study included 90,876 deliveries across 655 US hospitals. Controlling for patient race and ethnicity, insurance type, and obesity status: 10- to 13-year-olds had significantly higher risks of preterm delivery and cesarean delivery compared with 14- to 17-year-olds. The risk of preeclampsia was not higher for 10- to 13-year-olds compared to 14- to 17-year-olds. There was a higher risk of preterm delivery for 10- to 13-year-olds compared to 18- to 19-year-olds, but not significantly different for cesarean delivery and preeclampsia.

Association between folic acid prescription fills and suicide attempts and intentional self-harm among privately insured US adults.
This paper describes a large-scale pharmacoepidemiologic study of folic acid prescription fills to determine if there is a decreased risk of suicide attempt. Data were collected from a pharmacoepidemiologic database of US medical claims (MarketScan) for 866,586 patients with private health insurance who filled a folic acid prescription from 2012 to 2017. In the cohort 81.3% were female, and 10.42% were 60 years and older. Overall, there were 261 suicidal events during covered by a folic acid prescription for a rate of 4.73 per 100,000 person-months, compared with 895 suicidal events during months without folic acid for a rate of 10.61 per 100,000 person-months. Adjusting for age and sex, diagnoses related to suicidal behavior, diagnoses related to folic acid deficiency, folate-reducing medications, history of folate-reducing medications, and history of suicidal events, the hazard ratio (HR) for folic acid for suicide events was 0.56, with similar results for the modal dosage of 1 mg of folic acid per day and women of childbearing age. The same association with the negative control cyanocobalamin found no association with suicide attempt.

Perspectives of emergency clinicians about medical errors resulting in patient harm or malpractice litigation.
This cross-sectional study examined survey responses about medical error outcomes completed by emergency department attending physicians and advanced practice clinicians regarding what might be considered excessive testing. The authors surveyed 1222 clinicians and the mean score was greater for fear of harm to patients than fear of a malpractice suit. This finding was true regardless of clinician subtype, experience, or sex.

The modifying effect of the serum-to-dialysate potassium gradient on the cardiovascular safety of SSRIs in the hemodialysis population: a pharmacoepidemiologic study.
This study’s objective was to examine if higher QT-prolonging selective serotonin reuptake inhibitors (SSRIs) causes more cardiac risks to hemodialysis (HD) patients than lower serum-to-dialysate potassium gradient medications. The authors compared 1-year sudden cardiac death (SCD) risk among HD patients newly treated with higher (citalopram, escitalopram) versus lower (fluoxetine, fluvoxamine, paroxetine, sertraline) QT-prolonging potential SSRIs, overall and stratified by baseline potassium gradient. The study included 25,099 patients, with 44.3% newly prescribed higher QT-prolonging potential SSRIs and 55.7% lower QT-prolonging potential SSRIs. Overall, higher versus lower QT-prolonging potential SSRI use was not associated with SCD. However, a greater risk of SCD was associated with higher versus lower QT-prolonging potential SSRI use among patients with baseline potassium gradients ≥4 mEq/l but not among those with gradients <4 mEq/l versus 0.95.

This study’s objective was to develop hospital-level metrics of major complications associated with mortality that allows for the identification of opportunities for improvement and to improve upon current metrics for failure to rescue (i.e., death from serious but treatable complications.). The authors used AHRQ metrics as the basis for identifying specific complications related to major organ system morbidity associated with death. Using component ICD, 10th Revision codes, complication-specific occurrence rates, observed mortality, and risk-adjusted mortality indices were calculated for the study institution and 182 peer organizations. Statistically significant differences in the study hospital occurrence rates and associated mortality rates compared with peer institutions were shown with the complication-specific method. Use of a monthly control-chart presentation of these metrics provides assessment of hospital-level interventions to prevent complications and/or reduce failure to rescue deaths.

Comprehensive evaluation of the trends in length of stay and post-discharge complications after colon surgery in the USA.
The purpose of this study focusing on colon surgery was to 1) describe temporal changes in length of stay (LOS) and post-discharge complications and 2) assess risk factors related with post-discharge complications. The study found that of the 98,136 patients who underwent colon resection between 2012 and 2018, the median LOS decreased from 5 days in 2012 to 4 days in 2018. Overall, the 30-day complication rate was 21.5%, which decreased during the study period. Of the 13 individual complications evaluated, 4 demonstrated a significant increase in the proportion of post-discharge events including overall SSI, superficial SSI, wound disruption, and UTI. Factors associated with the development of any post-discharge complication included female sex, ASA III/IV/V, dependent functional status, and higher BMI. Intraoperative factors included wound class, operation time, and approach. The study concluded that LOS and 30-day complications decreased over time, however the percentage of incidents taking place post-discharge increased for a number of complications.

Frequency of diagnostic errors in the neonatal intensive care unit: a retrospective cohort study.
The objective of this study was to determine the frequency and etiology of diagnostic errors during the first 7 days of admission for inborn neonatal intensive care unit (NICU) patients. The "Safer Dx NICU Instrument" was used to review electronic health records. The reviewers discovered that the frequency of diagnostic error in inborn NICU patients during the first 7 days of admission was 6.2%.

Improving safety in the operating room: medication icon labels increase visibility and discrimination.
The purpose of this study was to assess whether the addition of icons to medication labels in an operating room setting would improve visibility and reduce medication administration errors. The multi-disciplinary team of researchers added icons to medication labels applied to vasoactive medication infusions, and the study found that participants were 1.12 times more likely to correctly identify medications with icons from farther away. In addition, when icons were present on the labels, participants were 2.16 times more likely to be more confident in their identifications.

Tolerance to oral anticancer agent treatment in older adults with cancer: a secondary analysis of data from electronic health records and a pilot study of patient-reported outcomes.
The purpose of this study was to explore the tolerance of capecitabine oral chemotherapy among older adults with cancer and investigate factors associated with related side effects and treatment changes. The researchers combined data from electronic health records and a pilot study of patient-reported outcomes, and found that older adults were more likely to experience fatigue and experienced more severe fatigue and hand-foot syndrome (HFS) than younger adults. The severity of fatigue and HFS were associated with the number of outpatient medications and the duration of treatment respectively. Female sex, breast cancer diagnosis, capecitabine monotherapy, and severe HFS were found to be associated with subsequent dose reductions. The study concluded that older adults were less likely to tolerate capecitabine treatment and had different co-occurring side effects compared to younger adults.

Association of injury after prescription opioid initiation with risk for opioid-related adverse events among older Medicare beneficiaries in the United States: a nested case-control study.
This study’s objectives were to examine the association between incident injury after prescription opioid initiation and subsequent risk of opioid-related adverse events (ORAEs) and to assess whether the association differs by recency of injury among older patients. The researchers observed that incident diagnosis of injury following opioid initiation was associated with subsequent increased risk of ORAEs, and the risk was only significant among patients with injury in the month before the index date. They recommended regular monitoring for injury in order to identify older opioid users at high risk for ORAEs.
