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 independent effect of cancer on outcomes: a potential limitation of surgical risk prediction.
This study aims to compare the use of common risk models for benign versus malignant gastrointestinal disease. It found that the National Surgical Quality Improvement Program (NSQIP) prediction models less effectively evaluate the risk of death in cancer patients as compared to patients with benign disease. A diagnosis of cancer is independently associated with an increased risk of surgical complications.

Postoperative hemorrhage and hospital revisit after transoral robotic surgery.
The researchers investigated the incidence and complications related to postoperative hemorrhage (POH) after transoral robotic surgery (TORS). Using HCUP data, they found that the incidence of POH after TORS was low, and few of these patients had a severe complication related to this event. Medical comorbidity and tonsillar subsite may be independent risk factors for POH.

Electronically available comorbidities should be used in surgical site infection risk adjustment.
A multicenter retrospective cohort study of patients undergoing surgical procedures at 28 US hospitals was performed. The authors developed a well-performing risk adjustment model for surgical site infections (SSI) using electronically available comorbidities. Healthcare-associated infections, such as SSIs, are used by the Centers for Medicare and Medicaid Services (CMS) as pay-for-performance metrics. The authors recommended that comorbidity-based risk adjustment should be strongly considered by the Centers for Disease Control and Prevention and CMS to adequately compare SSI rates across hospitals.

Prevalence and predictors of postdischarge antibiotic use following mastectomy.
This study determined utilization, predictors, and outcomes of postdischarge prophylactic antibiotics after mastectomy with or without immediate breast reconstruction. The study conclude that prophylactic postdischarge antibiotics are commonly prescribed after mastectomy; immediate reconstruction is the strongest predictor. The authors recommended stewardship efforts in this population to limit continuation of prophylactic antibiotics after discharge are needed to limit antimicrobial resistance.

A kidney graft survival calculator that accounts for mismatches in age, sex, HLA, and body size.
Models were adjusted for year of transplant and donor and recipient characteristics, with particular attention to mismatches in age, sex, human leukocyte antigens (HLA), body size, and weight. These models were used to create a calculator of estimated graft survival for living donors. This calculator provides useful information to donors, candidates, and physicians of estimated outcomes and potentially in allowing candidates to choose among several living donors.

A decision model to estimate a risk threshold for venous thromboembolism prophylaxis in hospitalized medical patients.
To determine a threshold for prophylaxis based on risk of venous thromboembolism, the researchers constructed a decision model with a decision-tree following patients for 3 months after hospitalization, and a lifetime Markov model with 3-month cycles. They found that the prophylaxis threshold was relatively insensitive to low-molecular-weight heparin cost and bleeding risk, but very sensitive to patient age and life expectancy.

Evaluating organizational factors associated with postoperative bariatric surgery readmissions.
This study evaluated the association between readmissions and several organizational factors, including compliance with best practices to reduce unplanned hospital visits, major complication rates, and the emergency department-sourced readmission rate. It concluded that bariatric centers with higher rates of major complications and sites with emergency departments that are less likely to treat and discharge patients are more likely to have higher readmission rates.

Estimating the risks of breast cancer radiotherapy: evidence from modern radiation doses to the lungs and heart and from previous randomized trials.
The researchers estimated the absolute long-term risks of modern breast cancer radiotherapy. They concluded that, for long-term smokers, the absolute risks of modern radiotherapy may outweigh the benefits, yet for most nonsmokers (and ex-smokers), the benefits of radiotherapy far outweigh the risks. Hence, smoking can determine the net effect of radiotherapy on mortality, but smoking cessation substantially reduces radiotherapy risk.

30-day hospital readmission following otolaryngology surgery: analysis of a state inpatient database.
Researchers sought to determine patient and hospital-level risk factors associated with 30-day readmission for patients undergoing inpatient otolaryngologic surgery. Approximately one out of 12 patients undergoing otolaryngologic surgery had a 30-day readmission. Readmissions occur across a variety of types of procedures and hospitals. Most of the variability was driven by patient-specific factors, not structural hospital characteristics.
