Association between hospital volume and failure-to-rescue for open repairs of juxtarenal aneurysms.

BACKGROUND: A nationwide variation in mortality stratified by hospital volume exists after open repair of complex abdominal aortic aneurysms (AAAs). In the present study, we assessed whether the rates of postoperative complications or failure-to-rescue (defined as death after a major postoperative complication) would better explain the lower mortality rates among higher volume hospitals. METHODS: Using the 2004 to 2018 Vascular Quality Initiative database, we identified all patients who had undergone open repair of elective or symptomatic AAAs, in which the proximal clamp sites were at least above one renal artery. We divided the patients into hospital quintiles according to the annual hospital volume and compared the risk-adjusted outcomes. Multivariable logistic regression, adjusted for patient characteristics, operative factors, and hospital volume, was used to evaluate three outcomes: 30-day mortality, overall complications, and failure-to-rescue. RESULTS: We identified 3566 patients who had undergone open repair of elective or symptomatic complex AAAs (median age, 71 years; 29% women; 4.1% black; 48% Medicare insurance). The unadjusted rates of 30-day postoperative mortality, overall complications, and failure-to-rescue were 5.0%, 44%, and 10%, respectively. Common complications included renal dysfunction (25%), cardiac dysrhythmia (14%), and pneumonia (14%), with the specific failure-to-rescue rate ranging from 12% to 22%. On adjusted analysis, the risk-adjusted mortality rate was 2.5 times greater for the lower volume hospitals relative to the higher volume hospitals (7.4% vs 3.0%; P < .01). Although the risk-adjusted complication rates were similar between these hospital groups (30% vs 27%; P = .06), the failure-to-rescue rate was 2.3 times greater for the lower volume hospitals relative to the higher volume hospitals (6.3% vs 2.7%; P = .02). CONCLUSIONS: Higher volume hospitals had lower mortality rates after open repair of complex AAAs because they were better at the "rescue" of patients after the occurrence of postoperative complications. Both an understanding of the clinical mechanisms underlying this association and the regionalization of open repair might improve patient outcomes.

Trauma complications and in-hospital mortality: failure-to-rescue.

BACKGROUND: Reducing medical errors and minimizing complications have become the focus of quality improvement in medicine. Failure-to-rescue (FTR) is defined as death after a surgical complication, which is an institution-level surgical safety and quality metric that is an important variable affecting mortality rates in hospitals. This study aims to examine whether complication and FTR are different across low- and high-mortality hospitals for trauma care. METHODS: This was a retrospective cohort study performed at trauma care hospitals registered at Japan Trauma Data Bank (JTDB) from 2004 to 2017. Trauma patients aged ≥ 15 years with injury severity score (ISS) of ≥ 3 and those who survived for > 48 h after hospital admission were included. The hospitals in JTDB were categorized into three groups by standardized mortality rate. We compared trauma complications, FTR, and in-hospital mortality by a standardized mortality rate (divided by the institute-level quartile). RESULTS: Among 184,214 patients that were enrolled, the rate of any complication was 12.7%. The overall mortality rate was 3.7%, and the mortality rate among trauma patients without complications was only 2.8% (non-precedented deaths). However, the mortality rate among trauma patients with any complications was 10.2% (FTR). Hospitals were categorized into high- (40 facilities with 44,773 patients), average- (72 facilities with 102,368 patients), and low- (39 facilities with 37,073 patients) mortality hospitals, using the hospital ranking of a standardized mortality rate. High-mortality hospitals showed lower ISS than low-mortality hospitals [10 (IQR, 9-18) vs. 11 (IQR, 9-20), P < 0.01]. Patients in high-mortality hospitals showed more complications (14.2% vs. 11.2%, P < 0.01), in-hospital mortality (5.1% vs. 2.5%, P < 0.01), FTR (13.6% vs. 7.4%, P < 0.01), and non-precedented deaths (3.6% vs. 1.9%, P < 0.01) than those in low-mortality hospitals. CONCLUSIONS: Unlike reports of elective surgery, complication rates and FTR are associated with in-hospital mortality rates at the center level in trauma care.

Postoperative Transcatheter Interventions in Children Undergoing Congenital Heart Surgery.

Background Postoperative transcatheter interventions (TCIs) are performed after congenital heart surgery to treat residual or recurrent anatomic lesions. We used the Society of Thoracic Surgeons Congenital Heart Surgery Database to evaluate rates of postoperative TCIs, center variability, and to determine whether center approaches to postoperative TCI might be associated with outcomes. Methods and Results Patients <18 years undergoing an index operation (2010-2016) were included. We determined predischarge postoperative TCI rates and used multivariable modeling, adjusting for patient factors and case complexity, to evaluate the association between center risk-adjusted postoperative TCI rates and risk-adjusted outcomes (operative mortality, post-TCI mortality, and failure-to-rescue). Postoperative TCI was performed after 2615/105 742 (2.5%) index operations and after 1443/25 416 (5.7%) highest complexity operations (STAT [Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery Mortality Score] Mortality Category 4 and 5). Median (interquartile range) age of patients undergoing TCI was 2.7 (0.2-8.0) months with 43% performed in neonates. There was a wide center variability across the 107 included centers with risk-adjusted rates of postoperative TCI ranging from 0.0% to 8.0% overall and 0.0% to 20.7% for STAT 4 and 5 cases. Postoperative TCI was associated with higher risk-adjusted odds of operative mortality (odds ratio, 4.06; 95% CI, 3.60-4.58). Centers with higher postoperative TCI rates had higher overall operative mortality ( R2=0.23; P=0.02) but did not have higher post-TCI mortality ( P=0.10). There was no correlation between center TCI rates and failure-to-rescue ( P=0.19). Conclusions Patients undergoing postoperative TCI represent a high-risk cohort. Wide center variability suggests the potential for improving outcomes, but further study is necessary to better understand optimal approaches.

Failure to Rescue, Communication, and Safety Culture.

Failure to rescue refers to the inability to prevent death from health care complications. The fact that more than half of severe maternal morbidity and maternal deaths are classified as preventable, and black women have 2 to 3 times the risk for adjusted severe morbidity and maternal mortality suggest there is a problem with failure to rescue in US maternity care. This article reviews national efforts to improve rescue capacity in maternity care and data on communication breakdowns and disrespect in maternity care, and outlines individual and organizational actions that can be taken to improve communication and rescue processes.

Impact of Approach and Hospital Volume on Cardiovascular Complications After Pulmonary Lobectomy.

BACKGROUND: Cardiovascular complications contribute significantly to the morbidity and resource utilization after pulmonary resections. Maturation of less-invasive technologies, such as video and robot-assisted thoracoscopic surgery, aims at improving postoperative outcomes by reducing the trauma of surgery. The present work aimed to evaluate changes in cardiovascular complications after open and minimally invasive lobectomies in the United States. METHODS: We performed a retrospective analysis of the Nationwide Inpatient Sample for patients having elective open, video-assisted, and robot-assisted thoracoscopic lobectomy during 2008-2014. Logistic regression was performed to determine predictors of in-hospital mortality, myocardial infarction (MI), cardiac arrest (CA), and postoperative pulmonary embolism (PE). RESULTS: A total of 201,226 patients underwent pulmonary lobectomy over the study period. Open thoracotomy (OPEN) approach has steadily decreased from 75%-52% (P < 0.0001), whereas minimally invasive surgery (MIS) utilization has increased from 25%-48% (P < 0.0001) of all lobectomies. MIS approach was independently associated with decreased odds of mortality (odds ratio [OR] 0.6, 95% confidence interval [CI] 0.50-0.73) and PE (OR 0.67, 95% CI 0.50-0.91). MIS patients at high volume institutions had the lowest odds of all-cause mortality (OR 0.27, 95% CI 0.26-0.53) and MI (OR 0.57, 95% CI 0.38-0.87). Operative approach and institutional lobectomy caseload reduced odds of mortality after MI, CA, or PE. Overall, the incidence of MI, CA, and PE increased. CONCLUSIONS: MIS lobectomies increased without a concurrent reduction in perioperative MI, CA, or PE incidence. High hospital lobectomy volume and MIS approach decrease odds of failure to rescue. Improved perioperative management of cardiovascular risk is warranted to reduce the morbidity, mortality, and resource utilization associated with these complications.

Impact of expanding indications on surgical and oncological outcome in 1434 consecutive pancreatoduodenectomies.

BACKGROUND: Over the years, high-volume pancreatic centers expanded their indications for pancreatoduodenectomy (PD) but with unknown impact on surgical and oncological outcome. METHODS: All consecutive PDs performed between 1992-2017 in a single pancreatic center were identified from a prospectively maintained database and analyzed according to three time periods. RESULTS: In total, 1434 patients underwent PD. Over time, more elderly patients underwent PD (P < 0.001) with increased use of vascular resection (10.4 to 16.0%, P < 0.001). In patients with cancer (n = 1049, 74.8%), the proportion pT3/T4 tumors increased from 54.3% to 70.6% over time (P < 0.001). The postoperative pancreatic fistula (16.0%), postpancreatectomy hemorrhage (8.0%) and delayed gastric emptying (31.0%) rate did not reduce over time, whereas median length of stay decreased from 16 to 12 days (P < 0.001). The overall failure-to-rescue rate (6.9%) and in-hospital mortality (2.2%) remained stable (P = 0.89 and P = 0.45). In 523 patients with pancreatic cancer (36.5%), the use of both adjuvant and neoadjuvant chemotherapy increased over time (both p<0.001), and the five-year overall survival improved from 11.0% to 17.4% (P < 0.001). CONCLUSIONS: In a period where indications for PD expanded, with more elderly patients, more advanced cancers and increased use of vascular resections, surgical outcome remained favorable and five-year survival for pancreatic cancer improved.

Variation in hospital mortality after pancreatoduodenectomy is related to failure to rescue rather than major complications: a nationwide audit.

BACKGROUND: In the mandatory nationwide Dutch Pancreatic Cancer Audit, rates of major complications and Failure to Rescue (FTR) after pancreatoduodenectomy between low- and high-mortality hospitals are compared, and independent predictors for FTR investigated. METHODS: Patients undergoing pancreatoduodenectomy in 2014 and 2015 in The Netherlands were included. Hospitals were divided into quartiles based on mortality rates. The rate of major complications (Clavien-Dindo ≥3) and death after a major complication (FTR) were compared between these quartiles. Independent predictors for FTR were identified by multivariable logistic regression analysis. RESULTS: Out of 1.342 patients, 391 (29%) developed a major complication and in-hospital mortality was 4.2%. FTR occurred in 56 (14.3%) patients. Mortality was 0.9% in the first hospital quartile (4 hospitals, 327 patients) and 8.1% in the fourth quartile (5 hospitals, 310 patients). The rate of major complications increased by 40% (25.7% vs 35.2%) between the first and fourth hospital quartile, whereas the FTR rate increased by 560% (3.6% vs 22.9%). Independent predictors of FTR were male sex (OR = 2.1, 95%CI 1.2-3.9), age >75 years (OR = 4.3, 1.8-10.2), BMI ≥30 (OR = 2.9, 1.3-6.6), histopathological diagnosis of periampullary cancer (OR = 2.0, 1.1-3.7), and hospital volume <30 (OR = 3.9, 1.6-9.6). CONCLUSIONS: Variations in mortality between hospitals after pancreatoduodenectomy were explained mainly by differences in FTR, rather than the incidence of major complications.

Mortalidad de las complicaciones postoperatorias (failure to rescue) tras cirugía cardiaca en un hospital universitario / Mortality from postoperative complications (failure to rescue) after cardiac surgery in a university hospital

Objetivo. Este estudio analiza la frecuencia de las complicaciones postoperatorias tras la cirugía cardiaca, la incidencia del fracaso en el rescate (FR) y su relación con la supervivencia. Métodos. Desde enero del 2003 hasta diciembre del 2009, se intervinieron 2.750 pacientes adultos de cirugía cardiaca. Se analizaron 9 complicaciones postoperatorias. Para conocer las variables asociadas con alguna de estas complicaciones, se realizó análisis de regresión logística múltiple. La supervivencia se estimó mediante curvas de Kaplan-Meier y las complicaciones asociadas con la mortalidad se estimaron mediante regresión de Cox. Resultados. La mortalidad hospitalaria fue 1,4% (IC del 95%, 1,01%-1,9%). La frecuencia de complicaciones postoperatorias fue del 38,5% (36,7%-40,4%) y el FR, 3,6% (2,5%-4,9%). La cirugía urgente (OR = 2,03, IC del 95%, 1,52-2,72), la insuficiencia renal crónica (OR = 1,50, IC del 95%, 1,25-1,80) y la edad ≥70 años (OR = 1,42, IC del 95%, 1,20-1,68) fueron las variables que se asociaron con más fuerza con las complicaciones seleccionadas. La supervivencia a los 5 años fue del 93% en los pacientes sin complicaciones y el 83% en los pacientes con alguna de las complicaciones (p < 0,0001). Las complicaciones asociadas con la supervivencia a medio plazo fueron la neumonía (HR 2,6, IC del 95%, 1,275,50), el infarto agudo de miocardio (HR 1,9, IC del 95%, 1,10-2,30) y la insuficiencia renal aguda (HR 1,7, IC del 95%, 1,30-2,26). Conclusiones. La incidencia de complicaciones postoperatorias en cirugía cardiaca oscila alrededor del 40% y aumenta la mortalidad hospitalaria aunque el FR fue muy bajo (3,6%; IC del 95%, 2,5-4,9) (AU)

Objective. This study analyses the rate of post-operative complications after cardiac surgery, the incidence of the failure to rescue (FR), and the relationship between complications and survival. Methods. The study included a total of 2,750 adult patients operated of cardiac surgery between January 2003 and December 2009. An analysis was made of 9 post-operative complications. Multiple logistic regression analysis was used to find independent variables associated with any of the selected complications. Survival was analysed with Kaplan-Meyer survival estimates. A risk-adjusted Cox proportional regression model was used to find out which complications were associated with mid-term survival. Results. Hospital mortality rate was 1.4% (95% CI: 1.0%-1.9%). Postoperative complications rate was 38.5% (36.7%-40.4%), and FR 3.6% (2.5%-4.9%). Urgent surgery (OR = 2.03; 1.52-2.72), chronic renal failure (OR = 1.50, 95%.CI: 1.25-1.80), and age ≥70 years (OR = 1.42; 1.20-1.68) were the variables that showed the highest strength of association with the selected complications. Survival at 5 years in the group of patients without complications was 93%, and in the group of patients with complications it was 83% (P<.0001). Postoperative complications associated with mid-term survival were pneumonia (HR = 2.6, 95% CI; 1.27-5.50), acute myocardial infarction (HR = 1.9; 1.10-2.30), and acute renal failure (HR = 1.7; 1.30-2.26). Conclusions. The incidence of complications after cardiac surgery is around 40%, and was associated with an increase in hospital mortality, although FR was very low (3.6%; 95% CI: 2.5-4.9) (AU)

Darunavir como tratamiento de rescate de la infección por virus de la inmunodeficiencia humana / Rescue therapy with darunavir for treatment-experienced HIV-infected patients

Darunavir es un inhibidor de la proteasa muy activo frente a cepas del virus de la inmunodeficiencia humana salvajes y multirresistentes, lo que ha permitido construir regímenes antirretrovirales eficaces en pacientes expuestos a numerosos antirretrovirales y que albergaban importantes resistencias farmacológicas. Además de su eficacia virológica, darunavir muestra otros aspectos relevantes como su tolerabilidad y su limitada toxicidad, lo que favorecería la adherencia al tratamiento. Estas observaciones son el resultado de numerosos ensayos clínicos (estudios POWER, DUET, BENCHMRK) llevados a cabo en combinación con diferentes antirretrovirales. Estos resultados se han confirmado en otros estudios llevados a cabo en el marco de la práctica clínica habitual, que han incluido el rescate tras fracaso a análogos no nucleósidos o como parte de terapias libres de análogos nucleósidos. Por estos motivos, en el momento actual, darunavir continúa siendo una opción terapéutica eficaz en los pacientes con fracasos terapéuticos previos que precisan un tratamiento antirretroviral optimizado

Darunavir (DRV) is a highly active protease inhibitor against wild-type and multidrug-resistant strains of human immunodeficiency virus that allows the design of effective antiretroviral regimens in patients previously exposed to antiretroviral agents and harboring many important drug resistances to the human immunodeficiency virus. In addition to its virological efficacy, DRV shows other important features, such as its tolerability and its limited toxicity, thereby encouraging adherence. These observations are the result of numerous clinical trials (POWER, DUET, BENCHMRK) carried out in combination with different antiretroviral drugs. These results have been confirmed in other studies conducted in the setting of routine clinical practice that included therapeutic rescue after failure to non-nucleoside analogues or as part of a nucleoside analogue-sparing regimen. For these reasons, DRV continues to be an effective treatment option in patients with previous treatment failures requiring an optimized antiretroviral régimen

Deconstructing the "July Effect" in Operative Outcomes: A National Study.

This study analyzes the relationship between hospital teaching status, failure to rescue, and time of year in select gastrointestinal operations. Procedure codes for laparoscopic cholecystectomy, colectomy, and pancreatectomy were queried from the Nationwide Inpatient Sample (2004-2011). Failure to rescue was defined as inpatient mortality when ≥1 complication. A total of 2,777,267 laparoscopic cholecystectomies, 2,519,903 colectomies, and 129,619 pancreatectomies were performed. Teaching hospitals had increased overall rates of failure to rescue compared to non-teaching hospitals, 10.0 vs. 9.5 % (p = 0.0187), particularly between May and August. There was greater inter-month variability in non-teaching hospitals amongst individual operations. On multivariable analysis, July was not predictive of increased odds of failure to rescue. Teaching status, hospital characteristics, and patient demographics were associated with increased odds of failure to rescue. Although teaching hospitals have a higher overall failure to rescue rate amongst the selected gastrointestinal operations, odds of failure to rescue are not increased in the month of July. Non-teaching hospitals tend to exhibit more monthly variation in failure to rescue rates, and hospital/patient demographics are predictive of failure to rescue. Further investigation targeted at identifying drivers of temporal variation is warranted to optimize patient outcomes.

Trends in Hospital Volume and Failure to Rescue for Pancreatic Surgery.

BACKGROUND: We sought to evaluate trends in selection of high volume (HV) hospitals for pancreatic surgery, as well as examine trends in preoperative complications, mortality, and failure to rescue (FTR). METHOD: Patients who underwent pancreatic resection between 2000 and 2011 were identified from the Nationwide Inpatient Sample (NIS). Preoperative morbidity, mortality, and FTR were examined over time. Hospital volume was stratified into tertiles based on the number of pancreatic resections per year for each time period. Logistic regression models were used to assess the effect of hospital volume on risk of complication, postoperative mortality, and FTR over time. RESULT: A total of 35,986 patients were identified. Median hospital volume increased from 13 in 2000-2003 to 55 procedures/year in 2008-2011 (P < 0.001). Morbidity remained relatively the same over time at low volume (LV), intermediate volume (IV), and HV hospitals (all P > 0.05). Overall postoperative mortality was 5%, and it decreased over time across all hospital volumes (P < 0.05). FTR was more common at LV (12.0%) and IV (8.5%) volume hospitals compared with HV hospitals (6.4%). The improvement in FTR over time was most pronounced at LV and IV hospitals versus HV hospitals (P = 0.001). CONCLUSION: Median hospital volume for pancreatic surgery has increased over the past decade. While the morbidity remained relatively stable over time, mortality improved especially in LV and IV hospitals. This improvement in mortality seems to be related to a decreased FTR.
