Perioperative ischemic optic neuropathy (ION) causes visual loss in spinal fusion. Previous case-control studies are limited by study size and lack of a random sample. The purpose this was to trends ION incidence fusion risk factors large nationwide administrative hospital database.In the Nationwide Inpatient Sample for 1998 2012, procedure codes posterior thoracic, lumbar, or sacral spine diagnostic were identified. studied over five 3-yr periods (1998 2000, 2001 2003, 2004 2006, 2007 2009,...
Study Design. Retrospective cohort utilizing the National Inpatient Sample (NIS) 2003 to 2014. Objective. To investigate association of opioid dependence with prolonged length stay (LOS), costs, and surgical complications in elective one-to-two level lumbar fusion. Summary Background Data. Opioids are most commonly prescribed drug class treat back pain. Few studies have examined impact on spinal fusion outcomes. The data available show inconsistent conclusions regarding between LOS. Methods....
Abstract Background For older, frail adults, exercise before surgery through prehabilitation (prehab) may hasten return recovery and reduce postoperative complications. We developed a smartwatch-based prehab program (BeFitMe) for older adults that encourages tracks at-home exercise. The objective of this study was to assess patient perceptions about facilitators barriers generally using smartwatch among adult thoracic patients optimize future implementation. Methods recruited patients, aged...
ABSTRACT Background Perioperative myocardial infarction (PMI) after noncardiac surgery results in significant morbidity and mortality. While comprehensive management, including imaging guideline‐directed medical therapy (GDMT), improves outcomes, utilization of these strategies the impact physician evaluation on their are unknown. This study evaluates frequency cardiology PMI its association with guideline‐recommended care. Methods Using IBM MarketScan (2016–2021), we analyzed claims for...
Ischemic optic neuropathy is the most common form of perioperative visual loss, with highest incidence in cardiac and spinal fusion surgery. To date, potential risk factors have been identified surgery by only small, single-institution studies. determine preoperative for ischemic neuropathy, authors used National Inpatient Sample, a database inpatient discharges nonfederal hospitals United States.Adults aged 18 yr or older admitted coronary artery bypass grafting, heart valve repair...
<h3>Background</h3> Local anesthetic systemic toxicity (LAST) is a rare and potentially devastating complication of regional anesthesia. Single-institution registries have reported decreasing incidence, but these results limited broad applicability. A recent study using US database found relatively high incidence LAST. We used the National Inpatient Sample, inpatient admissions, to identify national associated risk factors for LAST in total joint arthroplasties. <h3>Methods</h3> In this...
Cardiac stress testing is often performed prior to noncardiac surgery, although trends in use of preoperative and the effect on cardiovascular outcomes are currently unknown.To describe temporal cardiac from 2004 2017.Cross-sectional study patients undergoing elective total hip or knee arthroplasty 2017. Trend analysis was conducted using Joinpoint generalized estimating equation regression. The searched IBM MarketScan Research Databases inpatient outpatient health care claims for private...
<b><i>Background:</i></b> Functional capacity assessment is a critical step in the preoperative evaluation to identify patients at increased risk of cardiac complications and disability after major noncardiac surgery. Smartphones offer potential objectively measure functional but are limited by inaccuracy with poor capacity. Open-source methods exist analyze accelerometer data estimate gait cadence (steps/min), which directly associated activity intensity. Here, we...
The U.S. population is aging and projected to undergo an increasing number of general surgical procedures. However, recent trends in the frequency major abdominal procedures older adults are currently unknown as improvements non-operative interventions may obviate need for surgery. Thus, we evaluated United States.
Background Perioperative β-blocker therapy has been associated with increased risk of stroke. However, the association between initiation before day surgery and stroke is unknown. The authors hypothesized there would be no preoperative within 60 days or chronic β-blockade (more than days) in patients undergoing major abdominal surgery. Methods Data on elective were obtained from IBM (USA) Truven Health MarketScan 2005 to 2015 Commercial Medicare Supplemental Databases. Patients stratified by...
Abstract Background Comprehensive geriatric assessment (CGA) involves a formal broad approach to assess frailty and creating plan for management. However, the impact of CGA its components on listing kidney transplant in older adults has not been investigated. Methods We performed single-center retrospective study patients with end-stage renal disease who underwent during candidacy evaluation between 2017 2021. All ≥ 65 years old those under any team member concern were referred CGA, which...
Older adults with burn injuries have a high risk of readmission after the initial admission. Frailty is associated poor outcomes from injury, however, it remains unknown if frailty impacts in older index Our study aims to examine patient, frailty, burn, surgical, and hospital factors that contribute 90-day readmissions an acute burn. Patients ≥ 50 years age diagnosis Nationwide Readmissions Database (2016-2018) were included. who died during admissions excluded analysis. Patient, stay,...
Physicians underutilize adverse event reporting systems. Web-based platforms have increased participation; thus, it was hypothesized that a mobile application would increase reporting. The authors developed for iOS and Android operating systems performed retrospective review on rates by clinicians in the Department of Anesthesia Critical Care. Monthly were calculated intervention year 2 prior years (2013-2016). Wilcoxon rank sum test χ used to evaluate significance. Overall monthly all 15.3...
BACKGROUND: Functional capacity assessment plays a core role in the preoperative evaluation. The Duke Activity Status Index (DASI) and 6-minute walk test (6MWT) are 2 methods that have demonstrated ability to evaluate functional predict perioperative outcomes. Smartphones offer novel method facilitate as they can easily administer survey accelerometers track patient activity during 6MWT. We developed smartphone application 6MWT DASI performed pilot study accuracy of smartphone-based tool our...
Retinal artery occlusion (RAO) is a rare but devastating complication of spinal fusion surgery. We aimed to determine its incidence and associated risk factors.Hospitalizations involving surgery were identified by searching the National Inpatient Sample, database hospital discharges, from 1998 2013. RAO cases using ICD-9-CM codes. Using STROBE guidelines, postulated factors chosen based on literature review Multivariate logistic models with as outcome, factors, race, age, admission, type...
Introduction: Patients with coronavirus disease 2019 (COVID-19) can develop rapidly progressive respiratory failure. Ventilation strategies during the COVID-19 pandemic seek to minimize patient mortality. In this study we examine associations between availability of emergency department (ED)-initiated high-flow nasal cannula (HFNC) for patients presenting distress and outcomes, including rates endotracheal intubation (ETT), mortality, hospital length stay. Methods: We performed a...
( Reg Anesth Pain Med . 2018;43:113–123) Local anesthetic systemic toxicity (LAST) is a rare, adverse event that can occur when local anesthetics are administered despite advances in technique. Patients experience mild prodromal symptoms to serious events such as seizure, cardiac arrest, and/or death. It important all professionals administering be educated and prepared for LAST. This article uses emerging research update the 2010 advisory from American Society of Regional Anesthesia...
Central line insertion is a core skill for anesthesiologists. Although recent technical advances have increased the safety of central and reduced risk line-associated infection, noninvasive hemodynamic monitoring improved intravenous access techniques also need perioperative venous access. We hypothesized that number lines inserted by anesthesiologists has decreased over past decade. To test our hypothesis, we reviewed Medicare Physician Supplier Procedure Summary (PSPS) database from 2007...
