Association of Patient Characteristics With Postoperative Mortality in Children Undergoing Tonsillectomy in 5 US States.

Importance: The rate of postoperative death in children undergoing tonsillectomy is uncertain. Mortality rates are not separately available for children at increased risk of complications, including young children (aged <3 y) and those with sleep-disordered breathing or complex chronic conditions. Objective: To estimate postoperative mortality following tonsillectomy in US children, both overall and in relation to recognized risk factors for complications. Design, Setting, and Participants: Retrospective cohort study based on longitudinal analysis of linked records in state ambulatory surgery, inpatient, and emergency department discharge data sets distributed by the Healthcare Cost and Utilization Project for 5 states covering 2005 to 2017. Participants included 504 262 persons younger than 21 years for whom discharge records were available to link outpatient or inpatient tonsillectomy with at least 90 days of follow-up. Exposures: Tonsillectomy with or without adenoidectomy. Main Outcome and Measures: Postoperative death within 30 days or during a surgical stay lasting more than 30 days. Modified Poisson regression with sample weighting was used to estimate postoperative mortality per 100 000 operations, both overall and in relation to age group, sleep-disordered breathing, and complex chronic conditions. Results: The 504 262 children in the cohort underwent a total of 505 182 tonsillectomies (median [IQR] patient age, 7 [4-12] years; 50.6% females), of which 10.1% were performed in young children, 28.9% in those with sleep-disordered breathing, and 2.8% in those with complex chronic conditions. There were 36 linked postoperative deaths, which occurred a median (IQR) of 4.5 (2-20.5) days after surgical admission, and most of which (19/36 [53%]) occurred after surgical discharge. The unadjusted mortality rate was 7.04 (95% CI, 4.97-9.98) deaths per 100 000 operations. In multivariable models, neither age younger than 3 years nor sleep-disordered breathing was significantly associated with mortality, but children with complex chronic conditions had significantly higher mortality (16 deaths/14 299 operations) than children without these conditions (20 deaths/490 883 operations) (117.22 vs 3.87 deaths per 100 000 operations; adjusted rate difference, 113.55 [95% CI, 51.45-175.64] deaths per 100 000 operations; adjusted rate ratio, 29.39 [95% CI, 13.37-64.62]). Children with complex chronic conditions accounted for 2.8% of tonsillectomies but 44% of postoperative deaths. Most deaths associated with complex chronic conditions occurred in children with neurologic/neuromuscular or congenital/genetic disorders. Conclusions and Relevance: Among children undergoing tonsillectomy, the rate of postoperative death was 7 per 100 000 operations overall and 117 per 100 000 operations among children with complex chronic conditions. These findings may inform decision-making for pediatric tonsillectomy.

Early Postoperative Outcomes of Super Morbid Obese Compared to Morbid Obese Patients After Ambulatory Surgery Under General Anesthesia: A Propensity-Matched Analysis of a National Database.

BACKGROUND: Patients with body mass index (BMI) ≥50 kg/m2, defined as super morbid obesity, represent the fastest growing segment of patients with obesity in the United States. It is currently unknown if super morbid obese patients are at greater odds than morbid obese patients for poor outcomes after outpatient surgery. The main objective of the current investigation is to assess if super morbid obese patients are at increased odds for postoperative complications after outpatient surgery when compared to morbid obese patients. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database from 2017 to 2018 was queried to extract and compare patients who underwent outpatient surgery and were defined as either morbidly obese (BMI >40 and <50 kg/m2) or super morbidly obese (BMI ≥50 kg/m2). The primary outcome was the occurrence of medical adverse events within 72 hours of discharge. In addition, we also examine death and readmissions as secondary outcomes. A propensity-matched analysis was used to evaluate the association of BMI ≥50 kg/m2 versus BMI between 40 and 50 kg/m2 and the outcomes. RESULTS: A total of 661,729 outpatient surgeries were included in the 2017-2018 NSQIP database. Of those, 7160 with a BMI ≥50 kg/m2 were successfully matched to 7160 with a BMI <50 and ≥40 kg/m2. After matching, 17 of 7160 (0.24%) super morbid obese patients had 3-day medical complications compared to 15 of 7160 (0.21%) morbid obese patients (odds ratio [OR; 95% confidence interval {CI}] = 1.13 [0.57-2.27], P = .72). The rate of 3-day surgical complications in super morbid obese patients was also not different from morbid obese patients. Thirty-five of 7160 (0.48%) super morbid obese patients were readmitted within 3 days, compared to 33 of 7160 (0.46%) morbid obese patients (OR [95% CI] = 1.06 [0.66-1.71], P = .80). When evaluated in a multivariable analysis as a continuous variable (1 unit increase in BMI) in all patients, BMI ≥40 kg/m2 was not significantly associated with overall medical complications (OR [95% CI] = 1.00 [0.98-1.04], P = .87), overall surgical complication (OR [95% CI] = 1.02 [0.98-1.06], P = .23), or readmissions (OR [95% CI] = 0.99 [0.97-1.02], P = .8). CONCLUSIONS: Super morbid obesity is not associated with higher rates of early postoperative complications when compared to morbid obese patients. Specifically, early pulmonary complications were very low after outpatient surgery. Super morbid obese patients should not be excluded from outpatient procedures based on a BMI cutoff alone.

Safety of emergency, elective and day case operating during the winter period at East Suffolk and North Essex NHS Foundation Trust: lessons from the outcomes of 4,254 surgical patients from the first COVID-19 wave.

BACKGROUND: There is limited evidence on perioperative outcomes of surgical patients during the COVID-19 pandemic to inform continued operating into the winter period. METHODS: We retrospectively analysed the rate of 30-day COVID-19 transmission and mortality of all surgical patients in the three hospitals in our trust in the East of England during the first lockdown in March 2020. All patients who underwent a swab were swabbed on or 24 hours prior to admission. RESULTS: There were 4,254 patients and an overall 30-day mortality of 0.99%. The excess surgical mortality in our region was 0.29%. There were 39 patients who were COVID-19 positive within 30 days of admission, 12 of whom died. All 12 were emergency admissions with a length of stay longer than 24 hours. There were three deaths among those who underwent day case surgery, one of whom was COVID-19 negative, and the other two were not swabbed but not suspected to have COVID-19. There were two COVID-19 positive elective cases and none in day case elective or emergency surgery. There were no COVID-19 positive deaths in elective or day case surgery. CONCLUSIONS: There was a low rate of COVID-19 transmission and mortality in elective and day case operations. Our data have allowed us to guide patients in the consent process and provided the evidence base to restart elective and day case operating with precautions and regular review. A number of regions will be similarly affected and should perform a review of their data for the winter period and beyond.

Repercusión durante la pandemia por COVID-19 en la presentación de los casos quirúrgicos: experiencia en el Hospital de Clínicas de Uruguay / Impact of the COVID-19 pandemic on the presentation of surgical conditions: experience of Hospital de Clínicas in Uruguay

Antecedentes: La COVID-19 fue declarada por la OMS, el 11 de marzo de 2020, una emergencia sanitaria mundial. Como resultado de la pandemia, la consulta de pacientes en el Servicio de Emergencia se ha visto afectada, hecho que se refleja en las complicaciones evolutivas propias de la enfermedad. Objetivos: Evaluar el estadio evolutivo de la patología quirúrgica de urgencia al momento de la consulta en el contexto de la pandemia. Analizar la morbimortalidad posoperatoria. Analizar si hubo cambios en la selección del abordaje quirúrgico. Material y métodos: Se realizó un estudio retrospectivo, observacional, de cohortes, unicéntrico, en el centro universitario, Hospital de Clínicas. Con el fin de comparar dos poblaciones en el mismo intervalo de tiempo (13 de marzo al 13 de diciembre), se generaron dos grupos de estudio, diferenciándose ambos por la presencia de la pandemia COVID-19 y su influencia. Resultados: De una población total de 765 pacientes, 371 corresponden al Grupo A y 394 al Grupo B. La presencia de complicaciones evolutivas fue superior en el grupo influenciado por la pandemia (p = 0,0001), así como también la morbimortalidad posoperatoria (p = 0,001). El abordaje quirúrgico fue laparoscópico de preferencia en el Grupo B (p = 0,006) Conclusiones: En líneas generales, en el Hospital de Clínicas de Uruguay, la patología de urgencia de resorte quirúrgico se presentó en porcentajes similares en ambos períodos. Sin embargo, la presencia de complicaciones evolutivas y posoperatorias fue superior bajo la influencia de la pandemia, hecho esperable dada la consulta tardía de los pacientes.

Background: COVID-19 was declared a global health emergency by WHO on March 11, 2020. As a result of the pandemic, patients' visits to the emergency department have been affected and are reflected in the presence of complications associated with the course of the disease. Objectives: To evaluate the stage of the conditions requiring emergency surgery at the moment of consultation in the context of the pandemic. To analyze postoperative morbidity and mortality. To analyze if there were changes in the selection of the surgical approach. Material and methods: We conducted a single-center, retrospective and observational cohort study at the university center Hospital de Clínicas. Two study groups were generated to compare two populations over the same time interval (from March 13 to December 13), but differentiated by the presence of the COVID-19 pandemic and its influence. Results: The cohort was made up of 765 patients, 371 in group A and 394 in Group B. The presence of complications associated with the course of the disease and postoperative morbidity and mortality was higher in the group influenced by the pandemic (p = 0.0001 and p = 0.001, respectively). The laparoscopic approach was more common in group B (p = 0.006). Conclusions: In general, the percentage of emergency surgical conditions in Hospital de Clínicas of Uruguay was similar in both periods. The presence of complications associated with the course of the disease and postoperative morbidity and mortality was higher in the group influenced by the pandemic, as expected due to delays in consultations.

Safety of vascular interventions performed in an office-based laboratory in patients with low/moderate procedural risk.

OBJECTIVE: An exponential increase in number of office-based laboratories (OBLs) has occurred in the United States, since the Center for Medicare and Medicaid Services increased reimbursement for outpatient vascular interventions in 2008. This dramatic shift to office-based procedures directed to the objective to assess safety of vascular procedures in OBLs. METHODS: A retrospective analysis was performed to include all procedures performed over a 4-year period at an accredited OBL. The procedures were categorized into groups for analysis; group I, venous procedures; group II, arterial; group III, arteriovenous; and group IV, inferior vena cava filter placement procedures. Local anesthesia, analgesics, and conscious sedation were used in all interventions, individualized to the patient and procedure performed. Arterial closures devices were used in all arterial interventions. Patient selection for procedure at OBL was highly selective to include only patients with low/moderate procedural risk. RESULTS: Nearly 6201 procedures were performed in 2779 patients from 2011 to 2015. The mean age of the study population was 66.5 ± 13.31 years. There were 1852 females (67%) and 928 males (33%). In group I, 5783 venous procedures were performed (3491 vein ablation, 2292 iliac vein stenting); with group II, 238 arterial procedures (125 femoral/popliteal, 71 infrapopliteal, iliac 42); group III, 129 arteriovenous accesses; and group IV, 51 inferior vena cava filter placements. The majority of procedures belonged to American Society of Anesthesiology class II with venous (61%) and arterial (74%) disease. A total of 5% patients were deemed American Society of Anesthesiology class IV (all on hemodialysis). There was no OBL mortality, major bleed, acute limb ischemia, myocardial infarction, stroke, or hospital transfer within 72 hours. Minor complications occurred in 14 patients (0.5%). Thirty-day mortality, unrelated to the procedure, was noted in 9 patients (0.32%). No statistically significant differences were noted in outcomes between the four groups. CONCLUSIONS: Our data suggest that it is safe to use OBL for minimally invasive, noncomplex vascular interventions in patients with a low to moderate cardiovascular procedural risk.

Same-day discharge among patients undergoing elective PCI: Insights from the VA CART Program.

BACKGROUND: Available data suggest that same-day discharge (SDD) after elective percutaneous coronary intervention (PCI) is safe in select patients. Yet, little is known about contemporary adoption rates, safety, and costs in a universal health care system like the Veterans Affairs Health System. METHODS: Using data from the Veterans Affairs Clinical Assessment Reporting and Tracking Program linked with Health Economics Resource Center data, patients undergoing elective PCI for stable angina between October 1, 2007 and Sepetember 30, 2016, were stratified by SDD versus overnight stay. We examined trends of SDD, and using 2:1 propensity matching, we assessed 30-day rates of readmission, mortality, and total costs at 30 days. RESULTS: Of 21,261 PCIs from 67 sites, 728 were SDDs (3.9% of overall cohort). The rate of SDD increased from 1.6% in 2008 to 9.7% in 2016 (P < .001). SDD patients had lower rates of atrial fibrillation, peripheral arterial disease, and prior coronary artery bypass grafting and were treated at higher-volume centers. Thirty-day readmission and mortality did not differ significantly between the groups (readmission: 6.7% SDD vs 5.6% for overnight stay, P = .24; mortality: 0% vs. 0.07%, P = .99). The mean (SD) 30-day cost accrued by patients undergoing SDD was $23,656 ($15,480) versus $25,878 ($17,480) for an overnight stay. The accumulated median cost savings for SDD was $1503 (95% CI $738-$2,250). CONCLUSIONS: Veterans Affairs Health System has increasingly adopted SDD for elective PCI procedures, and this is associated with cost savings without an increase in readmission or mortality. Greater adoption has the potential to reduce costs without increasing adverse outcomes.

Retrospective single-centre series of 1300 consecutive cases of outpatient cervical spine surgery: complications, hospital readmissions, and reoperations.

Background: Outpatient surgery is becoming more common and is more cost-effective than inpatient surgery. Nonetheless, many surgeons and health care administrators are still hesitant to accept outpatient surgery for cervical degenerative spinal disease (C-DSD). This study assesses the types and rates of complications, hospital admissions, and reoperations after outpatient surgery of C-DSD.Methods: Complications, hospital admissions within 90 days of surgery, and reoperations within one year of surgery were recorded retrospectively in 1300 outpatients undergoing microsurgical decompression for C-DSD at the Oslofjord Clinic from 2008 to 2017. The surgical procedures performed were anterior cervical decompression and fusion (ACDF) in 1083 patients and posterior cervical foraminotomy in 217 patients.Results: The surgical mortality rate was 0%. Sixteen major complications were recorded in 15/1300 (1.2%) patients. The complications were neurological deterioration in four patients, postoperative hematoma in two, dural lesions with cerebrospinal fluid leakage in one, deep surgical-site infection in one, persistent hoarseness in three, and persistent dysphagia in five. The two potentially life-threatening hematomas were detected within the planned six-hour observation period. Two (0.2%) patients were admitted to hospital within hours of surgery completion with stroke-like signs and symptoms, and four (0.3%) patients were admitted to hospital within 90 days due to surgery-related events. The rate of reoperations for cervical radiculopathy within 12 months was 25/1171 (2%); eight patients' reoperations were due to inadequate primary decompression, one was due to recurrent disc herniation at the same level and side, and 16 were due to new-onset radiculopathy from an adjacent level or other side.Conclusions: Outpatient microsurgical decompression of the degenerative cervical spine in carefully selected patients appears to be safe and carries a low major complication rate, low hospital admission rate, and low one-year reoperation rate.

Association Between Heart Failure and Postoperative Mortality Among Patients Undergoing Ambulatory Noncardiac Surgery.

Importance: Heart failure is an established risk factor for postoperative mortality, but how heart failure is associated with operative outcomes specifically in the ambulatory surgical setting is not well characterized. Objective: To assess the risk of postoperative mortality and complications in patients with vs without heart failure at various levels of echocardiographic (left ventricular systolic dysfunction) and clinical (symptoms) severity who were undergoing ambulatory surgery. Design, Setting, and Participants: In this US multisite retrospective cohort study of all adult patients undergoing ambulatory, elective, noncardiac surgery in the Veterans Affairs Surgical Quality Improvement Project database during fiscal years 2009 to 2016, a total of 355 121 patient records were identified and analyzed with 1 year of follow-up after surgery (final date of follow-up September 1, 2017). Exposures: Heart failure, left ventricular ejection fraction, and presence of signs or symptoms of heart failure within 30 days of surgery. Main Outcomes and Measures: The primary outcomes were postoperative mortality at 90 days and any postoperative complication at 30 days. Results: Among 355 121 total patients, outcome data from 19 353 patients with heart failure (5.5%; mean [SD] age, 67.9 [10.1] years; 18 841 [96.9%] male) and 334 768 patients without heart failure (94.5%; mean [SD] age, 57.2 [14.0] years; 301 198 [90.0%] male) were analyzed. Compared with patients without heart failure, patients with heart failure had a higher risk of 90-day postoperative mortality (crude mortality risk, 2.00% vs 0.39%; adjusted odds ratio [aOR], 1.95; 95% CI, 1.69-2.44), and risk of mortality progressively increased with decreasing systolic function. Compared with patients without heart failure, symptomatic patients with heart failure had a greater risk of mortality (crude mortality risk, 3.57%; aOR, 2.76; 95% CI, 2.07-3.70), as did asymptomatic patients with heart failure (crude mortality risk, 1.85%; aOR, 1.85; 95% CI, 1.60-2.15). Patients with heart failure had a higher risk of experiencing a 30-day postoperative complication than did patients without heart failure (crude risk, 5.65% vs 2.65%; aOR, 1.10; 95% CI, 1.02-1.19). Conclusions and Relevance: In this study, among patients undergoing elective, ambulatory surgery, heart failure with or without symptoms was significantly associated with 90-day mortality and 30-day postoperative complications. These data may be helpful in preoperative discussions with patients with heart failure undergoing ambulatory surgery.

Patient Safety in Outpatient Procedures.

The past 4 decades have seen a remarkable re-engineering of health care, particularly with respect to surgical services and the formalization of patient safety protocols. As various forces drove many surgical procedures to the ambulatory setting, many advantages, and perhaps several disadvantages, quickly became apparent. In some studies, adverse events were found to be more common in office settings for instance, and it was quickly recognized that the formal quality controls that had evolved in the hospital setting were not always transferred to the outpatient facility. This article traces the development of health care's response to this challenge.

Ambulatory Surgery Center Medical Director: Visionary Leader.

The ambulatory surgery center medical director is a physician leader who recognizes the need to develop a culture that encourages communication and empowerment of employees and professional staff, leading to engagement that optimize care through patient selection, safety and satisfaction requires vision and guidance from the medical director and is central to success of the ASC. Innovative thinking further improves patient care and long-term success by leveraging advances in technology and sustainable practices.

Safety and efficacy of outpatient sleeve gastrectomy: 2534 cases performed in a single free-standing ambulatory surgical center.

BACKGROUND: Sleeve gastrectomy (SG) is currently the most widely performed operation for treatment of morbid obesity. SG leads to significant weight loss and reduction in weight related comorbidities. Procedures performed in ambulatory surgical centers (ASC) can provide several advantages over hospital-based surgery. We present results of 2,534 consecutive patients who underwent SG in an ASC. OBJECTIVE: Assess the safety and efficacy of outpatient SG in a freestanding ASC. SETTING: Free-standing ASC, Eviva Bariatrics, Seattle WA. METHODS: Data was collected retrospectively for all patients undergoing SG from January 2008 - January 2018, n = 2,534. Revisional procedures were not excluded from this study. Patients were excluded from the ASC if they weighed >450 pounds, if anticipated surgery time was > 2 hours, if the patient had impaired mobility limiting early ambulation, or if there were medical problems requiring postoperative monitoring beyond 23 hours. RESULTS: Mean age was 45.9 years. Mean preoperative body mass index (BMI) was 41.9. Mean operative time was 70 minutes. 30-day complications included 3 mortalities (0.12%), 60 (2.53%) re-admissions, 35 (1.42%), re-operations, and 31 (1.22%) direct transfers from the ASC to a nearby hospital. There were 25 staple line leaks (0.99%). There were no open conversions. At 6 months average excess body weight loss (EWL) was 56.3% and total weight loss (TWL) was 20.9% (n = 1,758/2,303). At 1 year, EWL was 70.1% and TWL was 26.4% (n = 1,199/2,125). CONCLUSION: With experienced surgeons, appropriate protocols, and a consistent operative team, SG can be performed safely in a free-standing ASC.

Total Hip Arthroplasty and the Medicare Inpatient-Only List: An Analysis of Complications in Medicare-Aged Patients Undergoing Outpatient Surgery.

BACKGROUND: The Centers for Medicare and Medicaid Services has solicited public comments for the 2019 Proposed Rule to remove total hip arthroplasty (THA) from the inpatient-only list. Concerns exist regarding the safety of discharging higher risk Medicare patients as an outpatient and whether hospitals may still be reimbursed for an inpatient procedure. The purpose of this study is to determine whether Medicare-aged patients undergoing outpatient THA have higher complication rates than patients who underwent inpatient THA. We also sought to identify characteristics of Medicare-aged patients that are associated with increased risk of complications or longer stay following short-stay THA. METHODS: We queried the American College of Surgeons National Surgical Quality Improvement Program database for patients over age 65 who underwent primary THA between 2015 and 2016. We compared demographics, comorbidities, and 30-day complication, reoperation, and readmission rates among outpatient, short-stay, and inpatient groups. A multivariate regression analysis identified patients who are at an increased risk for complications and a longer inpatient stay following short-stay THA. RESULTS: Of the 34,416 Medicare-aged patients who underwent THA, 310 (1%) were discharged on postoperative day 0, 5698 (16.5%) on postoperative day 1, and 28,408 (82.5%) were inpatients. The outpatient and short-stay patients had lower 30-day complication and readmission rates than the inpatient group. Independent risk factors for developing a complication or requiring an inpatient stay included general anesthesia, body mass index >35 kg/m2, diabetes, chronic obstructive pulmonary disease, congestive heart failure, hypertension, malnutrition, female gender, age >75 years, minority ethnicity, and an American Society of Anesthesiologists score of 4 (all P < .05). CONCLUSION: Outpatient and short-stay THA appears to be safe in a small subset of Medicare-aged patients. Centers for Medicare and Medicaid Services should allow surgeons flexibility in determining admission status based on each patient's risk profile.

Short-term Outcomes of Ambulatory Colectomy for 157 Consecutive Patients.

OBJECTIVE: To evaluate short-term outcomes of laparoscopic colectomy for selected consecutive patients in an ambulatory setting at two institutions. BACKGROUND: Several studies showed that an enhanced recovery protocol for colorectal surgery reduces postoperative morbidity and mortality, and shortens the length of hospital stay. The development of such a program has allowed us to gradually reduce the length of stay for colorectal surgery, until ambulatory management. METHODS: Between February, 2013 and December, 2016, all patients scheduled for elective laparoscopic colectomy and meeting rigorous criteria for ambulatory surgery were included. Outcome was prospectively studied. RESULTS: One hundred fifty-seven patients (70 women) with a median age of 61 years (range 25-82 years) were included. The ambulatory rate for colectomy was 30.5%. Median operative time and length of in-hospital stay were 95 minutes (range 45-232 minutes) and 10.0 hours (range 7-14.7 hours), respectively. The admission rate was 7.0% due to operative difficulties (4 patients), medical reasons (4 patients), and social reasons (3 patients). Outcomes for these patients were uneventful and the median length of hospital stay was 3.1 days (range 1-14 days). An unscheduled consultation was necessary for 30 patients (20.5%). Nine patients required readmission (6.1%), of whom 6 required reoperation (3.8%). The overall 30-day morbidity rate was 24.8%. The mortality rate was 0%. CONCLUSIONS: This is the first case of consecutive patients undergoing ambulatory colectomy for malignant or benign disease. We demonstrated the feasibility, safety, and reproducibility of outpatient colectomy for selected patients. In our experience, 30% of patients scheduled for elective colectomy can be managed in an ambulatory setting.

Vascular access surgery can be safely performed in an ambulatory setting.

INTRODUCTION:: Ambulatory surgery is associated with lower costs, but there is lack of evidence of the safety for ambulatory vascular access surgery. The objective of this study is to substantiate the safety and effectiveness of performing vascular access surgery in an ambulatory setting. METHODS:: A review of our prospectively maintained database including all vascular access open surgeries (creations and repairs) performed by our Vascular Access Unit between 2013 and 2017 was compiled. Patient comorbidities, surgery details, hospital admission conditions, and 1-week and 1-month follow-up patency and complications (death, infection, bleeding, and readmission/reintervention) were scrutinized. RESULTS:: In the last 5 years, 1414 vascular access procedures were performed (67.8% access creations, 32.2% previous access repairs) in 1012 patients. Most surgeries were performed under local anesthesia (59.2%) or axillary plexus block (38.4%) and mainly in an ambulatory setting, without overnight hospital stays (90.9%). During the first postoperative week follow-up, 9 cases (0.6%) needed readmission or reintervention; significant infection materialized in 11 (0.8%) and 10 cases (0.7%) showed noteworthy hematoma or bleeding, only three (0.2%) requiring reintervention. The primary composite endpoint of 24-h death and 1 week readmission, reintervention, infection, or bleeding was 1.9% (27 cases); 1-month access failure was 6.2%. After univariate analysis, ambulatory settings were not related to higher rates of complications or readmissions. CONCLUSION:: Arteriovenous access surgery can be safely performed in an ambulatory setting, in spite of complex cases, comorbidities, or the increasing implementation of axillary plexus blocks. Surgical results and patency are good, and complications necessitating readmission remain very low.

National Mortality Rates after Outpatient Cosmetic Surgery and Low Rates of Perioperative Deep Vein Thrombosis Screening and Prophylaxis.

BACKGROUND: Concerns have arisen over reports of deaths occurring after certain outpatient plastic surgery procedures. Here, the authors present a national analysis, reporting on deaths occurring after outpatient cosmetic surgical procedures and venous thromboembolism screening. METHODS: A retrospective analysis of the American Association for Accreditation of Ambulatory Surgical Facilities database was performed for the years 2012 to 2017. The authors retrieved data for all deaths occurring in association with cosmetic plastic surgery procedures. Patient demographics, procedural data, venous thromboembolism risk factor assessment, and cause of death were analyzed. Deidentified medical records, including coroner's reports, were reviewed where available. RESULTS: Data for 42 deaths were retrieved. Of these, 90.5 percent (n=38) were female, and 61.9 percent were Caucasian (n=26). Mean age was 51.6 years, while mean body mass index was 29.5 kg/m(2). Overall, 54.8 percent of these deaths occurred after abdominoplasty: 42.9 percent in isolation, 9.5 percent in combination with breast surgery, and 2.4 percent with facial surgery. Of the causes of death, most (38.1 percent) were thromboembolic in origin. Notably, in 25 of 42 cases, venous thromboembolism risk factor assessment was incorrect or absent (59.5 percent). CONCLUSIONS: Accreditation agencies provide transparency and insight into outpatient surgical mortality on a national scale. Results suggest that adoption of venous thromboembolism screening techniques may not be universal despite an existing large body of published evidence. Optimization of thromboembolism prevention pathways remains vital, and consideration of anticoagulation in those undergoing abdominoplasty may be important in lowering outpatient mortality.

A ten-year analysis of the reasons for death following ambulatory surgery: Nine closed claims declared to the SHAM insurance.

INTRODUCTION: The constant development of ambulatory surgery (AS) raises the problem of monitoring patients after discharge and the risk of death in the case of delays in the management of a serious complication. PATIENTS AND METHODS: The aim of this retrospective study was to describe the deaths observed within the 30-day period following AS declared to the SHAM insurance (Société hospitalière d'assurance mutuelle) over the last 10 years. RESULTS: During the study period 33,962 claims were surgery-related and 11 were for deaths after AS. Two of the death claims were excluded from our study because they occurred after the first month. The surgeries concerned were tonsilectomy (3), cataract (2), inguinal hernia (2), varicose vein stripping (1) and laparoscopy (1). Death occurred on average 5.4 days after the AS, in intensive care (3), during hospitalisation (2), with emergency medical services (1), in an emergency department (1) or at home (2). Anaesthesia was directly implicated in 3 cases: anaphylactic shock (Diamox), pneumoperitoneum (gastric swelling) and hemoperitoneum (mismanagement of anticoagulants). 1 case was due to a pulmonary embolism and 5 to a surgical cause. DISCUSSION-CONCLUSION: There was only one case where the complication was aggravated due to the delay of care provision and this was because of a lack of information on the complications requiring an emergency return (abdominal pain after laparoscopy). In all the other cases, death would also probably have occurred during conventional hospitalisation, either because it was unavoidable or because the patient was too far from the surgery.

Temporal Trends, Determinants, and Outcomes of Inpatient versus Outpatient Arteriovenous Fistula Operations.

BACKGROUND: As high healthcare costs are increasing scrutinized, a movement toward reducing patient hospital admissions and lengths of stay has emerged, particularly for operations that may be performed safely in the outpatient setting. Our aim is to describe recent temporal trends in the proportion of dialysis access procedures performed on an inpatient versus outpatient basis and to determine the effects of these changes on perioperative morbidity and mortality. METHODS: The 2005-2008 American College of Surgeons National Surgical Quality Improvement Program database was queried for all primary arteriovenous fistula (AVF) procedures using current procedural terminology codes. Changes in the proportions of inpatient versus outpatient operations performed by year, as well as the associated 30-day postoperative morbidity and mortality, were analyzed using univariable statistics and multivariable logistic regression. RESULTS: Two thousand nine hundred fifty AVF procedures were performed over the study period. Overall, 71.7% (n = 2,114) were performed on an outpatient basis. Inpatient procedures were associated with higher 30-day morbidity (10.5% vs. 4.5%) and mortality (2.8% vs. 0.7%) than outpatient procedures (both, P < 0.001). There was a significant increase in the proportion of procedures performed on an outpatient basis over time (2005: 56% vs. 2008: 75%; P < 0.001). There were no changes in postoperative morbidity or mortality for inpatient or outpatient AVF over time (P ≥ 0.36). Independent determinants of having an inpatient procedure included younger age (OR 0.99), increasing ASA class (ASA IV OR 1.56), congestive heart failure (OR 3.32), recent ascites (OR 3.25), poor functional status (OR 3.22), the presence of an open wound (OR 1.91), and recent sepsis (OR 6.06) (all, P < 0.01). Acute renal failure (OR 2.60) and current dialysis (OR 1.44) were also predictive (P < 0.001). After correcting for baseline differences between groups, the adjusted OR for both morbidity (aOR 1.93, 95% CI 1.38-2.69) and mortality (aOR 2.85, 95% CI 1.36-5.95) remained significantly higher for inpatient versus outpatient AVF. CONCLUSIONS: Dialysis access operations are increasingly being performed on an outpatient basis, with stable perioperative outcomes. Inpatient procedures are associated with worse outcomes, likely because they are reserved for patients with acute illnesses, serious comorbidities, and poor functional status. Overall, for appropriately selected patients, the movement toward performing more elective dialysis access operations on an outpatient basis is associated with acceptable outcomes.
