Risk of tizanidine-induced adverse events after concomitant exposure to ciprofloxacin: a cohort study in the U.S.
This study’s aim was to assess the risk of hypotension with coadministration of tizanidine (a painkiller medicine) and ciprofloxacin (an antibiotic). An observational nested cohort study was conducted using patients 18 years or older on tizanidine using data from electronic health records from 2000 to 2018 in the US. The analysis included 70,110 encounters across 221 hospitals. Most encounters were female (65.7%), whites (82.4%) with an average age of 56 years and an Elixhauser comorbidity index of 1.6. Only 2487 encounters (3.6%) had a co-administration of ciprofloxacin. An increased likelihood of hypotension was associated with co-administration compared to patients who did not receive ciprofloxacin.

Development and validation of a model for prediction of end-stage liver disease in people with HIV.
The authors developed and validated a risk-prediction model for end-stage liver disease (ESLD) among people with HIV (PWH). They developed and validated a risk prediction model for ESLD among PWH who received care in 12 cohorts of the North American AIDS Cohort Collaboration on Research and Design and found that their model of readily accessible clinical parameters predicted ESLD in a large diverse population of PWH.

Collaborative design and implementation of a clinical decision support system for automated fall-risk identification and referrals in emergency departments.
The authors used a collaborative and iterative approach to design and implement an automated clinical decision support system (CDS) for Emergency Department (ED) providers to identify and refer older adult ED patients at high risk of future falls. The system was developed using collaborative input from an interdisciplinary design team and integrated seamlessly into existing ED workflows. A key feature of development was the unique combination of patient experience strategies, human-centered design, and implementation science, which allowed for the CDS tool and intervention implementation strategies to be designed simultaneously. Challenges included: usability problems, data inaccessibility, time constraints, low appointment availability, high volume of patients, and others. The study concluded that using the collaborative, iterative approach was successful in achieving all project goals, and could be applied to other cases.

Delivery characteristics and the risk of early-onset neonatal sepsis.
This retrospective cohort study identified term and preterm infants at lowest risk of culture-confirmed early-onset sepsis (EOS) using delivery characteristics and also determined antibiotic use among them. The study cohort included term and preterm infants born 2009 to 2014 with blood culture with or without cerebrospinal fluid culture obtained ≤72 hours after birth. Low EOS risk criteria included: cesarean delivery, without labor or membrane rupture before delivery, and no antepartum concern for intraamniotic infection or nonreassuring fetal status. Among 53,575 births, 7549 (14.1%) were evaluated and 41 (0.5%) of those infants had EOS. For 1121 evaluated infants there were low-risk delivery characteristics and none had EOS. Duration of antibiotics administered to infants born with and without low-risk characteristics was not different.

Early parental knowledge of late effect risks in children with cancer.
This study assessed early parental knowledge of late effect risks in children with cancer. The cohort included parents of children receiving cancer treatment at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center. The parents were surveyed about their knowledge of their child’s likelihood of eight late effects. Only 11 out of 96 parents correctly identified all their child’s risk for the eight late effects. Five of eight effects were the median number of correctly identified late effect risks. Among the 21 parents whose children were at risk for ototoxicity, 95% correctly identified this risk. Conversely, parents were less knowledgeable about risks of second malignancy, cardiac toxicity, neurocognitive impairment, and infertility.

Risk of opioid overdose associated with concomitant use of oxycodone and selective serotonin reuptake inhibitors.
Oxycodone is a potent prescription opioid. Some Selective Serotonin Reuptake Inhibitors (SSRIs) inhibit oxycodone metabolism in the body, but the clinical consequences of this interaction on overdose risk have not been adequately determined. The study researchers compared the rates of opioid overdoses in patients who had initiated oxycodone while taking enzyme-inhibiting SSRIs with the overdose rates of patents who had initiated oxycodone while taking non-enzyme inhibiting SSRIs. Data from 3 U.S. health insurance databases was used to analyze a cohort of adults who initiated oxycodone while receiving SSRI therapy between the years 2000 and 2020. Of the total of 2,037,490 who initiated oxycodone, 69.6% were receiving SSRIs at the time of the initiation of the oxycodone. One-thousand-thirty-five overdose events were observed during this time, and the resulting incidence rate in those initiating oxycodone while using enzyme-inhibiting SSRI’s was higher than in those using other SSRIs. The researchers concluded that in the study cohort of U.S. adults, there is a small increased risk of opioid overdose when initiating oxycodone in patients taking enzyme-inhibiting SSRIs.

Assessing the influence of patient language preference on 30 day hospital readmission risk from home health care: a retrospective analysis.
In home health care, language barriers are understudied. Language barriers between patients and providers are known to affect a variety of patient outcomes. How a patient's language preference influences hospital readmission risk from home health care has yet to be determined. The objective of this retrospective cross-sectional study was to determine if home care patients' language preference is associated with their risk for hospital readmission from home health care within 30 days of hospital discharge.

Association between race and perioperative outcomes after carotid endarterectomy for asymptomatic carotid artery stenosis in NSQIP.
This study investigated the association of race on carotid endarterectomy (CEA) outcomes. Perioperative outcomes (at 30 days) were compared for Black vs. White patients adjusting for age/sex, comorbidities and disease characteristics. Out of 16,764 patients from the ACS-NSQIP targeted vascular database (2011-2019), 95.2% were White and 4.8% were Black. Black patients were slightly younger and more frequently (79.5% vs 74.0%) had high-grade carotid artery stenosis compared to White patients. Comorbidities including hypertension, diabetes, kidney disease, congestive heart failure, and coronary artery disease were all more prevalent among Black patients. Crude perioperative stroke and stroke/death were higher for Black patients, but myocardial infarction leading to death were similar. After adjusting for baseline differences between groups, the risk of perioperative stroke and stroke/death remained significantly higher for Black patients than White patients.

Comparing health care system and physician practice influences on social risk screening.
This study examined the association of multilevel organizational capabilities and adoption of social risk screening among system-owned physician practices. A secondary analysis of the 2018 National Survey of Healthcare Organizations and Systems data was conducted. Five social risks were used as measures for physician and system screening: food insecurity, housing instability, utility needs, interpersonal violence, and transportation needs. System-owned practices screened an average of 1.7 of the 5 social risks assessed. The differences were 16% attributable to practice variation between their health system owners, and 84% attributable to differences between individual practices. Practices owned by hospital systems screened for an additional 0.44 social risks relative to practices of systems without hospitals. Characteristics associated with more social risk screening included health information technology capacity, innovation culture, and patient engagement strategies.

Readmission rates in stroke patients with and without infections: incidence and risk factors.
Investigators examined whether an infection acquired during the initial stroke admission contributed to increased risk of readmission and infection during readmission. Their a retrospective cohort study incorporated all adult ischemic stroke patients 2006-2016 from three New York City hospitals. They found that, among stroke patients, healthcare-associated infections and infections present on admission were predictors of readmission within 60 days and infection during readmission.

Risk factors for opioid-related adverse drug events among older adults after hospital discharge.
This study examined patient- and prescribing-related risk factors for opioid-related adverse drug events (ADEs) after hospital discharge among medical patients. Administrative billing codes and medication claims were used to define potential opioid-related ADEs within 30 days of hospital discharge. Findings showed that potential opioid-related ADEs occurred in 7% of older adults discharged from a medical hospitalization with an opioid prescription. Recommendations included using identified risk factors to inform physician decision-making, having conversations with older adults about risk, and increasing development and targeting of harm reduction strategies.

A risk prediction model to identify newborns at risk for missing early childhood vaccinations.
Approximately 30% of US children aged 24 months have not received all recommended vaccines. This retrospective cohort study aimed to develop a prediction model to identify newborns at high risk for missing early childhood vaccines. The investigators concluded that their prediction model using information readily available in birth hospitalization records consistently identified newborns at high risk for undervaccination.

Preeclampsia predicts risk of hospitalization for heart failure with preserved ejection fraction.
Preeclampsia is associated with increased risk of future heart failure (HF), but the relationship between preeclampsia and HF subtypes are not well-established. The objective of this analysis was to identify the risk of HF with preserved ejection fraction (HFpEF) following a delivery complicated by preeclampsia/eclampsia. The investigators concluded that preeclampsia/eclampsia was an independent risk factor for future hospitalizations for HFpEF.

A comparison of administrative claims-based risk predictors for pediatric asthma.
This retrospective cohort study used 2013-2014 MarketScan Medicaid data to compare administrative claims-based risk predictors of emergency department (ED) visits for pediatric asthma. The cohort included were children aged 2 to 17 years. Seven risk predictors were compared for 3-month subsequent ED visits/hospitalizations: 3-month rolling asthma medication ratio (AMR), Healthcare Effectiveness Data and Information Set (HEDIS) criteria, revised HEDIS criteria, quarterly short-acting β-agonist (SABA) claims, prior ED visit, prior hospitalization, and prior ED visit or hospitalization. Sensitivity, specificity, positive and negative predictive value (PPV and NPV), and percentage of population identified as high risk were compared for each risk predictor utilization the McNemar test. Cohort total population was 214,452 children with a mean age of 7.8 years. HEDIS and revised HEDIS identified prohibitively large cohorts as high-risk (67% and 48%). For the remaining measures, the NPV range was 97% to 99%, indicating high performance at identifying patients who would not benefit from intervention using AMR and SABA count. Superior sensitivities were found for ED visit and ED/hospitalization measures compared with pharmacy claims-based measures.

Modeling the impact of delaying surgery for early esophageal cancer in the era of COVID-19.
Surgical society guidelines have recommended changing the treatment strategy for early esophageal cancer during the novel coronavirus (COVID-19) pandemic. Delaying resection can allow for interim disease progression, but the impact of this delay on mortality is unknown. The COVID-19 infection rate at which immediate operative risk exceeds benefit is unknown. In this study, the investigators sought to model immediate versus delayed surgical resection in a T1b esophageal adenocarcinoma.

Outcomes of a presurgical optimization program for elective hernia repairs among high-risk patients.
The authors evaluated the feasibility of evidence-based patient optimization before surgery by implementing a low-cost preoperative optimization clinic. They found that a hernia optimization clinic safely improved management of high-risk patients and increased operative yield for the institution. They concluded that their results represented an opportunity to create sustainable and scalable models that provide longitudinal care and optimize patients to improve outcomes of hernia repair.

Predictors and outcomes of heart block during surgical stage I palliation of patients with a single ventricle: a report from the NPC-QIC.
This study investigated patient and surgical risks of heart block and its effect on 12-month transplant-free survival in children with a single ventricle. In total, 1423 patients were identified from the National Pediatric Cardiology Improvement Collaborative with and without heart block. One-year outcomes were analyzed. A very small percentage (2%) developed heart block during their surgical admission. Associated risk factors for block included heterotaxy syndrome and atrial flutter/fibrillation. Patients with complete heart block had lower 12-month survival, which wasn’t true for patients with second degree block. At 12 months of age, 43% of patients with heart block died and were more likely to experience mortality than patients without heart block.

Attitudes toward risk among emergency physicians and advanced practice clinicians in Massachusetts.
Risk aversion is a personality trait influential to decision making in medicine. Little is known about how emergency department (ED) clinicians differ in their attitudes toward risk taking. In this study, the investigators conducted a cross-sectional survey of practicing ED clinicians (physicians and advanced practice clinicians [APCs]) in Massachusetts using the following 4 existing validated scales: the Risk-Taking Scale (RTS), Stress from Uncertainty Scale (SUS), the Fear of Malpractice Scale (FMS), and the Need for (Cognitive) Closure Scale (NCC).

Perioperative risks of sleeve gastrectomy versus roux-en-Y gastric bypass among patients with chronic kidney disease: a review of the MBSAQIP database.
The purpose of this study was to determine whether patients with chronic kidney disease experienced higher rates of perioperative complications after roux-en-Y gastric bypass (RYGB) compared to sleeve gastrectomy. The investigators concluded that among well-matched cohorts of RYGB and sleeve gastrectomy patients, incidence of primary outcomes were similar. Among secondary outcomes, only acute kidney injury was statistically-significantly higher among RYGB patients; however, the E-value for this difference was small and relatively weak confounder(s) could abrogate the statistical difference.
