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.

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.

Comparative effectiveness of machine learning approaches for predicting gastrointestinal bleeds in patients receiving antithrombotic treatment.
The purpose of this retrospective cross-sectional study was to compare the performance of 3 machine learning approaches with the commonly-used HAS-BLED (hypertension, abnormal kidney and liver function, stroke, bleeding, labile international normalized ratio, older age, and drug or alcohol use) risk score in predicting antithrombotic-related gastrointestinal bleeding (GIB). The machine-learning models were regularized Cox proportional hazards regression (RegCox), random survival forests, and extreme gradient boosting (XGBoost). Findings showed that the machine learning models revealed similar performance in identifying patients at high risk for GIB after being prescribed antithrombotic agents. Two models (RegCox and XGBoost) performed modestly better than the HAS-BLED score.

Racial/ethnic differences in the risk of surgical complications and posthysterectomy hospitalization among women undergoing hysterectomy for benign conditions.
The objective of this retrospective cohort study was to evaluate whether 30- and 90-day surgical complication and postoperative hospitalization rates after hysterectomy for benign conditions differed by race/ethnicity and whether the differences remained after controlling for patient, hospital, and surgical characteristics. The investigators concluded that Black and Asian/Pacific Islander women had higher risk of some 30- and 90-day surgical complications after hysterectomy than white women. Black and Hispanic women had higher risk of posthysterectomy hospitalization.

Renal failure among multiple myeloma patients utilizing carfilzomib and associated factors in the "real world."
Researchers investigated the rate of renal failure and associated risk factors in real-world populations of patients with multiple myeloma taking carfilzomib. Using Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data, they found that renal failure developed in 22% of patients during the study period. The median time to development of renal failure from first carfilzomib administration was 1.6 months. Increasing age, pre-existing heart failure, and pre-existing chronic kidney disease were associated with a higher risk of developing renal failure. As their study could not determine the exact cause and mechanism of renal failure, they recommended future studies to further understand this cause among patients on carfilzomib and to devise strategies to mitigate the risk.

Risk of systemic adverse events after intravitreal bevacizumab, ranibizumab, and aflibercept in routine clinical practice.
Intravitreal anti-vascular endothelial growth factor (VEGF) pharmacotherapy plays a central role in the management of neovascular age-related macular degeneration (nAMD), diabetic retinal disease (DRD), and retinal venous occlusive disease (RVO). The goal of this study was to compare the systemic safety of intravitreal bevacizumab, ranibizumab, and aflibercept in real-world practice. The investigators observed no differences in the risk of acute MI, CVD, major bleeding, or all-cause hospitalization after treatment initiation with intravitreal bevacizumab, ranibizumab, or aflibercept during routine clinical practice.

A postdischarge venous thromboembolism risk calculator for inflammatory bowel disease surgery.
Guidelines recommend extended chemoprophylaxis for venous thromboembolism in high-risk patients having operations for inflammatory bowel disease. Quantifying patients' risk of venous thromboembolism, however, remains challenging. In this study, the investigators sought (1) to identify factors associated with postdischarge venous thromboembolism in patients undergoing colorectal resection for inflammatory bowel disease and (2) to develop a postdischarge venous thromboembolism risk calculator to guide prescribing of extended chemoprophylaxis.

Oral glucocorticoids and incident treatment of diabetes mellitus, hypertension, and venous thromboembolism in children.
The purpose of this study was to quantify rates of incident treatment for diabetes mellitus, hypertension, and venous thromboembolism (VTE) associated with oral glucocorticoid exposure in children aged 1-18 years. Participants were identified using US Medicaid claims data and included more than 930,000 children diagnosed with autoimmune diseases or a nonimmune comparator condition. Findings showed strong dose-dependent relationships between current glucocorticoid exposure and all outcomes, suggesting strong relative risks, but low absolute risks, of newly-treated VTE, diabetes, and especially hypertension in children taking high-dose oral glucocorticoids.

Risk factors associated with 30-day hospital readmission after carotid endarterectomy.
This study looked at the risk factors associated with 30-day hospital readmission after carotid endarterectomy. Patients in the Cerner Health Facts® database were selected using ICD-9-CM procedure codes. A total of 5257 patients were identified who had undergone elective carotid endarterectomy. Readmission was associated with end-stage renal disease, hemorrhage or hematoma, procedural complications, use of bronchodilators, electrolyte abnormalities, and hypokalemia less than 3.7 mEq/L. Although protamine reduces the risk of bleeding complications, only 40% of patients received that medication.

Risk of kidney failure, death, and cardiovascular events after lower limb complications in patients with CKD.
Investigators sought to determine how interim lower limb complications modify the subsequent risk of progression to kidney failure, all-cause mortality before kidney failure, and cardiovascular events in a cohort of patients with chronic kidney disease (CKD) stages G3 to G5. Patient-level data obtained from several administrative databases from Manitoba, Canada, were analyzed. They found that interim lower limb complications were associated with an increased risk of kidney failure, all-cause mortality before kidney failure, and cardiovascular-related hospitalization. They stated that clinical trials of screening and treatment strategies for patients with CKD at risk for lower limb complications may help determine optimal strategies to manage this risk.

Risk factors associated with medication ordering errors.
This study’s goal was to collect data on “voided” orders in computerized order entry systems for medication to 1) identify the nature and characteristics of medication ordering errors; 2) investigate the risk factors associated with these errors and; 3) explore potential strategies to mitigate these risk factors. Data was collected using clinician interviews and surveys within 24 hours of the voided order and using chart reviews. During the 16-month study period 1074 medication orders were voided, with 842 being true medication errors. A total of 22% reached the patient, with at least a single administration, but without causing patient harm. Interviews were conducted on 355 voided orders (33%). Errors were associated with multiple factors not just a single risk factor. The causal contributors included a combination of technological-, cognitive-, environment-, social-, and organization-level factors.

The incremental risk of noncardiac surgery on adverse cardiac events following coronary stenting.
The investigators sought to determine the incremental risk of noncardiac surgery on myocardial infarction (MI) and coronary revascularization following coronary stenting. They found that the incremental risk of noncardiac surgery on adverse cardiac events among post-stent patients is highest in the initial 6 months following stent implantation and stabilizes at 1.0% after 6 months.

An evaluation of differences in risk factors for individual types of surgical site infections after colon surgery.
The authors developed four independent, multivariate, predictive models to assess the unique associations between risk factors and each surgical site infection (SSI) group: superficial, deep, organ space, and an aggregate of all 3 types of SSIs. They found that unique risks for superficial SSIs include diabetes, chronic obstructive pulmonary disease, and dyspnea; deep SSIs had the greatest magnitude of association with BMI and the greatest incidence of wound disruption; and organ space SSIs were often owing to anastomotic leaks and were uniquely associated with disseminated cancer, preoperative dialysis, preoperative radiation treatment, and a bleeding disorder. They concluded that more effective prevention strategies may be developed by reporting and examining each type of SSI separately.

A socio-technical, probabilistic risk assessment model for surgical site infections in ambulatory surgery centers.
The researchers sought to identify the risk factors associated with surgical site infections (SSIs) resulting from procedures performed at ambulatory surgery centers (ASCs) and to design an intervention to mitigate the likelihood of SSIs for the most common risk factors that were identified by the socio-technical probabilistic risk assessment (ST-PRA) tool for a particular surgical procedure. They found that failure to protect the patient effectively accounted for 51.9% of SSIs in the ambulatory care setting. Critical components of this event included skin preparation, antibiotic administration, staff training, proper response to glove punctures during surgery, and adherence to surgical preparation rules related to the wearing of jewelry, watches, and artificial nails. They determined that, assuming a 75% reduction in noncompliance on any combination of 2 of these 5 components, the risk for an SSI decreased.

Bisphosphonates and hip and nontraumatic subtrochanteric femoral fractures in the Veterans Health Administration.
This study examined associations between bisphosphonate use and nontraumatic subtrochanteric (NTST) femoral fractures and hip fractures in the Veterans Health Administration. It found that nontraumatic subtrochanteric femoral fractures were uncommon, and longer bisphosphonate use was associated with lower (not higher) risk. In men, risks of NTST femoral fractures associated with bisphosphonate treatment may be low in contrast to substantial protective benefits for hip fracture.

Predictors of early treatment discontinuation in a cohort of patients treated with boceprevir-based therapy for hepatitis C infection.
This study aimed to assess early treatment discontinuation rates and identify underlying risk factors for discontinuation in a real-world boceprevir-based treatment cohort. Nearly half of patients started on boceprevir-based hepatitis C triple therapy stopped treatment by 24 weeks, with more discontinuing because of treatment intolerance than virologic failure. Early discontinuation was significantly more common in patients with comorbidities.

Comparison of postoperative complication risk prediction approaches based on factors known preoperatively to surgeons versus patients.
The objective of this paper was to compare three estimation models: (1) the All Information Model; (2) the Surgeon Assessment Model; and (3) the Patient-Entered Model. The investigators observed a small decline in model performance that they suggest may not be clinically meaningful. They concluded that the Surgeon Assessment and Patient-Entered models with fewer predictors can be used with relative confidence to predict a patient's risk.

Association of Nurse-to-Patient Ratio with mortality and preventable complications following aortic valve replacement.
The purpose of this study was to examine hospital resources associated with patient outcomes for aortic valve replacement (AVR), including inpatient adverse events and mortality. The investigators found that the hospital volume-outcomes relationship was associated with mortality outcomes but not postoperative complications. They identified structural differences in hospital size, nurses-to-patient ratio, and nursing skill level indicative of high quality outcomes.
