Risk factors for opioid-related adverse drug events among older adults after hospitalization for major orthopedic procedures.
The purpose of this retrospective cohort study was to identify risk factors for opioid-related adverse drug events (ORADEs) after hospital discharge following orthopedic procedures. The participants of this study included a national sample of Medicare beneficiaries who underwent major orthopedic surgery during hospitalization in 2016 and had an opioid prescription filled within 2 days of discharge. The study found that among 30,514 hospitalizations with a major orthopedic procedure and an opioid claim, a potential ORADE requiring hospital revisit occurred in 2.5%. After adjustment for patient characteristics, prior opioid use, co-prescribed sedating medications, and opioid prescription characteristics were not related with ORADEs. Independent risk factors did include age of 80 years or older, female sex, and clinical conditions, including heart failure, respiratory illness, kidney disease, dementia/delirium, anxiety disorder, and musculoskeletal/nervous system injuries.

The additional cost of perioperative medication errors.
The aim of this study was to calculate the additional annual cost to the U.S. healthcare system attributable to preventable medication errors (MEs) in the operating room. The ME types were grouped into 13 categories by their related harm (or potential harm), and researchers calculated the incidence of operations involving each ME category: 1) delayed or missed required perioperative antibiotic; 2) prolonged hemodynamic swings; 3) untreated postoperative pain; 4) residual neuromuscular blockade; 5) oxygen saturation <90% due to ME; 6) delayed emergence; 7) untreated new onset intraoperative cardiac arrhythmia; 8) medication documentation errors; 9) syringe swaps; 10) presumed hypotension with inability to obtain a blood pressure reading; 11) potential for bacterial contamination due to expired medication syringes; 12) untreated bradycardia <40 beats/min; and 13) other. Through a PubMed search, the researchers established the possibility that the ME category would cause downstream patient harm such as surgical site infection or acute kidney injury, and the additional fully allocated cost of care for each potential downstream patient harm event. The cost of the MEs across the U.S. healthcare system was then calculated by scaling the number of MEs to the total number of annual operations in the United States. The total additional fully allocated annual cost of care due to perioperative MEs was estimated to be $5.33 billion U.S. dollars.

Effect of postoperative antithrombotic therapy on lower extremity outcomes after infrapopliteal bypass for chronic limb-threatening ischemia.
This study’s goal was to examine the effects of different postoperative antithrombotic regimens on 3-year clinical outcomes after infrapopliteal bypass for chronic limb-threatening ischemia (CLTI). The authors identified patients who had undergone infrapopliteal bypass for CLTI in the Vascular Quality Initiative (VQI) registry from 2003 to 2017 with linkage to Medicare claims for long-term outcomes. They divided the patients into three cohorts according to the discharge antithrombotic regimen: single-antiplatelet therapy (SAPT; aspirin or clopidogrel), dual antiplatelet therapy (DAPT; aspirin and clopidogrel), or anticoagulation (AC) plus any antiplatelet (AP) agent. To reduce selection bias, they restricted the analysis cohorts to patients treated by providers who discharged >50% of patients with each antithrombotic regimen. Their primary outcome was 3-year major adverse limb events (MALE; major amputation or reintervention). Among 1812 patients with a median follow-up time of >2 years, 693 (38%) were discharged with SAPT, 544 (30%) with DAPT, and 575 (32%) with AC+AP. At 3 years, MALE rates were 75% with DAPT, 74% with AC+AP, and 68% with SAPT. In adjusted analyses with SAPT as the reference group, no differences were found in 3-year MALE with DAPT or AC+AP. Across the treatment groups, we also found no differences in the individual end points of 3-year major amputation (DAPT: aHR, 0.98; AC+AP: aHR, 1.3), reintervention (DAPT: aHR, 1.0; AC+AP: aHR, 1.1), or mortality (DAPT: aHR, 1.1; AC+AP: aHR, 0.95).

Efficacy and safety of perioperative dual antiplatelet therapy with ticagrelor versus clopidogrel in carotid artery stenting.
This study’s objective was to compare the efficacy and safety of perioperative dual antiplatelet therapy with aspirin/ticagrelor vs aspirin/clopidogrel in patients undergoing transfemoral carotid artery stenting (tfCAS) or transcarotid artery revascularization (TCAR). The authors identified all patients who underwent tfCAS or TCAR in the Vascular Quality Initiative registry from January 2016 to March 2021. They stratified patients by procedure and assessed outcomes using 1:3 propensity score-matched cohorts of patients who received perioperative aspirin/ticagrelor vs aspirin/clopidogrel. Among the cohort of 17,731 tfCAS patients, 593 (3.3%) received aspirin/ticagrelor and 11,404 (64%) received aspirin/clopidogrel. For the 2065 matched patients, no significant differences were found in the composite endpoint of stroke/death (aspirin/ticagrelor, 4.1%; vs aspirin/clopidogrel, 2.6%) or in the individual endpoints of stroke (2.9% vs 1.8%) or death (1.7% vs 1.1%). However, aspirin/ticagrelor was associated with a higher risk of bleeding (5.8% vs 2.8%). In a subgroup analysis of 297 tfCAS patients (14%) who received intraoperative protamine, no differences remained in stroke/death (1.5% vs 3.9%), and there was no longer a difference in bleeding (3.0% vs 2.6%). Among 17,946 TCAR patients, 453 (2.5%) received aspirin/ticagrelor and 13,696 (76%) received aspirin/clopidogrel. With the 1618 matched patients, no differences were found in stroke/death (0.7% vs 1.4%), stroke (0.2% vs 1.2%), death (0.5% vs 0.2%), or bleeding (1.2% vs 1.6%). For the 1429 TCAR patients (88%) who received protamine, no differences were found in stroke/death (0.8% vs 1.2%) or bleeding (0.6% vs 1.4%).

Systematic review and meta-analysis of the association between non-steroidal anti-inflammatory drugs and operative bleeding in the perioperative period.
Investigators sought to understand the risk of bleeding caused by NSAIDs in the perioperative period. They performed a systematic review of articles on the use of NSAIDs and outcomes of interest such as surgical complications and bleeding, then conducted a meta-analysis of the data. They concluded that NSAIDs were unlikely to be the cause of postoperative bleeding complications. The literature studied covered a large number of patients and remained consistent across types of NSAIDs and operations.

Exposure to general anesthesia for cesarean delivery and odds of severe postpartum depression requiring hospitalization.
This retrospective cohort study evaluated the risk of general anesthesia use in cesarean delivery versus neuraxial anesthesia on maternal mental health. Cesarean deliveries performed in New York State hospitals between 2006 and 2013 were included. Exclusion criteria included having more than 1 cesarean delivery during the study period, residing outside of New York State, and having a general anesthetic for other surgery or delivery in the year before or after the index case. The primary outcome looked at was severe postpartum depression (PPD), and secondary outcomes were suicidal ideation, anxiety disorders, and posttraumatic stress disorder (PTSD). The majority of cesareans used neuraxial anesthesia and only 8% (34,356) had general anesthesia. Severe PPD requiring hospitalization occurred in 1158 women with 60% identified during readmission. General anesthesia was found to be associated with a 54% increased odds of PPD, and a 91% increased odds of suicidal ideation or self-inflicted injury. There was insufficient evidence for increased risk of anxiety orders.

Exposure to surgery and anesthesia in early childhood and subsequent use of attention deficit hyperactivity disorder medications.
This study examines the association between higher rates of attention deficit hyperactivity disorder (ADHD) diagnosis and exposure to surgery and anesthesia before the age of 5. Longitudinal pharmacy data for children enrolled in Texas and New York Medicaid from 1999 to 2010 were used. They examined the association between a single exposure to anesthesia before age 5 years for 1 of 4 common pediatric surgical procedures: pyloromytomy, inguinal hernia repair, circumcisions outside the perinatal period, and tonsillectomy and/or adenectomy; and persistent ADHD medication use. A total of 213,435 children were included in the study. Children with a single exposure to anesthesia were 37% more likely than unexposed children to persistently use ADHD medication.

A systems theoretic process analysis of the medication use process in the operating room.
While 4 to 10% of medications administered in the operating room may involve an error, few investigations have prospectively modeled how these errors might occur. Systems theoretic process analysis is a prospective risk analysis technique that uses systems theory to identify hazards. The purpose of this study was to demonstrate the use of systems theoretic process analysis in a healthcare organization to prospectively identify causal factors for medication errors in the operating room.

Incidence and classification of nonroutine events during anesthesia care.
A nonroutine event is any aspect of clinical care perceived by clinicians or trained observers as a deviation from optimal care based on the context of the clinical situation. The authors sought to delineate the incidence and nature of intraoperative nonroutine events during anesthesia care. The investigators concluded that nonroutine event-containing cases were commonly associated with patient impact and injury. They indicated that nonroutine event monitoring in conjunction with traditional error reporting may enhance understanding of potential intraoperative failure modes to guide prospective safety interventions.

Cost-benefit limitations of extended, outpatient venous thromboembolism prophylaxis following surgery for Crohn's disease.
This goal of this study was to assess the cost-effectiveness of extended prophylaxis in patients with Crohn's disease after abdominal surgery. A decision tree model was used to assess cost-effectiveness and cost-per-case averted with extended-duration venous thromboembolism prophylaxis following abdominal surgery. Results showed that extended prophylaxis in patients with Crohn's disease postoperatively is not cost-effective when the cumulative incidence of posthospital thrombosis remains less than 4.9%. These findings are driven by the low absolute risk of thrombosis in this population and the considerable cost of universal treatment.

Adverse events and factors associated with potentially avoidable use of general anesthesia in cesarean deliveries.
Compared with neuraxial anesthesia, general anesthesia for cesarean delivery is associated with increased risk of maternal adverse events. Reducing avoidable general anesthetics for cesarean delivery may improve safety of obstetric anesthesia care. This study examined adverse events, trends, and factors associated with potentially avoidable general anesthetics for cesarean delivery. The investigators concluded that compared with neuraxial anesthesia, avoidable general anesthetics are associated with increased risk of adverse maternal outcomes.

Perioperative timing of infliximab and the risk of serious infection after elective hip and knee arthroplasty.
The purpose of this retrospective cohort study was to evaluate the association between infliximab timing and serious infection after elective hip or knee arthroplasty. The investigators concluded that administering infliximab within 4 weeks of elective knee or hip arthroplasty was not associated with a higher risk of short- or long-term serious infection compared to withholding infliximab for longer time periods. They also concluded that glucocorticoid use, especially >10 mg/day, was associated with an increased infection risk.

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.
