RESUMO

Background: Adrenalectomies are rare procedures especially in childhood. So far, no large cohort study on this topic has been published with data on to age distribution, operative procedures, hospital volume and operative outcome. Methods: This is a retrospective analysis of anonymized nationwide hospital billing data (DRG data, 2009-2017). All adrenal surgeries (defined by OPS codes) of patients between the age 0 and 21 years in Germany were included. Results: A total of 523 patient records were identified. The mean age was 8.6 ± 7.7 years and 262 patients were female (50.1%). The majority of patients were between 0 and 5 years old (52% overall), while 11.1% were between 6 and 11 and 38.8% older than 12 years. The most common diagnoses were malignant neoplasms of the adrenal gland (56%, mostly neuroblastoma) with the majority being younger than 5 years. Benign neoplasms in the adrenal gland (D350) account for 29% of all cases with the majority of affected patients being 12 years or older. 15% were not defined regarding tumor behavior. Overall complication rate was 27% with a clear higher complication rate in resection for malignant neoplasia of the adrenal gland. Bleeding occurrence and transfusions are the main complications, followed by the necessary of relaparotomy. There was an uneven patient distribution between hospital tertiles (low volume, medium and high volume tertile). While 164 patients received surgery in 85 different "low volume" hospitals (0.2 cases per hospital per year), 205 patients received surgery in 8 different "high volume" hospitals (2.8 cases per hospital per year; p<0.001). Patients in high volume centers were significant younger, had more extended resections and more often malignant neoplasia. In multivariable analysis younger age, extended resections and open procedures were independent predictors for occurrence of postoperative complications. Conclusion: Overall complication rate of adrenalectomies in the pediatric population in Germany is low, demonstrating good therapeutic quality. Our analysis revealed a very uneven distribution of patient volume among hospitals.

RESUMO

BACKGROUND: Validity of the laparoscopic approach in pancreatic head lesion remains debatable. This study aims to compare the safety and effectiveness of laparoscopic pancreatoduodenectomy (LPD) and open pancreatoduodenectomy (OPD) and investigate the source of heterogeneity from surgeons' and patients' perspectives. METHOD: We searched PubMed, Cochrane, Embase, and Web of Science for studies published before February 1, 2021. Of 6578 articles, 81 were full-text reviewed. The primary outcome was mortality. Three independent reviewers screened and extracted the data and resolved disagreements by consensus. Studies were evaluated for quality using ROB2.0 and ROBINS-I. According to different study designs, sensitivity and meta-regression analyses were conducted to explore the heterogeneity source. This meta-analyses was also conducted to explore the learning curve's heterogeneity. This study was registered with PROSPERO, CRD42021234579. RESULTS: We analyzed 34 studies involving 46,729 patients (4705 LPD and 42,024 OPD). LPD was associated with lower (P = 0.025) in unmatched studies (P = 0.017). No differences in mortality existed in randomized controlled trials (P = 0.854) and matched studies (P = 0.726). Sensitivity analysis found no significant difference in mortality in elderly patients, patients with pancreatic cancer, and in high- and low-volume hospitals (all P > 0.05). In studies at the early period of LPD (<40 cases), higher mortality (P < 0.001) was found (all P < 0.05).LPD showed non-inferiority in length of stay, complications, and survival outcomes in all analyses. CONCLUSION: In high-volume centers with adequate surgical experience, LPD in selected patients appears to be a valid alternative to LPD with comparable mortality, LOS, complications, and survival outcomes.

RESUMO

BACKGROUND: Centralization for complex cancer surgery may not always be feasible owing to socioeconomic disparities, geographic constraints, or patient preference. The present study investigates how the combined volume of complex cancer operations impacts postoperative outcomes at hospitals that are low-volume for a specific high-risk cancer operation. STUDY DESIGN: Patients who underwent pneumonectomy, esophagectomy, gastrectomy, hepatectomy, pancreatectomy, or proctectomy were identified from the National Cancer Database (2004-2017). For every operation, 3 separate cohorts were created: low-volume hospitals (LVH) for both the individual cancer operation and the total number of those complex operations, mixed-volume hospital (MVH) with low volume for the individual cancer operation but high volume for total number of complex operations, and high-volume hospitals (HVH) for each specific operation. RESULTS: LVH was significantly (all p ≤ 0.01) predictive for 30-day mortality compared with HVH across all operations: pneumonectomy (9.5% vs 7.9%), esophagectomy (5.6% vs 3.2%), gastrectomy (6.8% vs 3.6%), hepatectomy (5.9% vs 3.2%), pancreatectomy (4.7% vs 2.3%), and proctectomy (2.4% vs 1.3%). Patients who underwent surgery at MVH and HVH demonstrated similar 30-day mortality: esophagectomy (3.2 vs 3.2%; p = 0.993), gastrectomy (3.2% vs 3.6%; p = 0.637), hepatectomy (3.8% vs 3.2%; p = 0.233), pancreatectomy (2.8% vs 2.3%; p = 0.293), and proctectomy (1.2% vs 1.3%; p = 0.843). Patients who underwent pneumonectomy at MVH demonstrated lower 30-day mortality compared with HVH (5.4% vs 7.9%; p = 0.045). CONCLUSION: Patients who underwent complex operations at MVH had similar postoperative outcomes to those at HVH. MVH provide a model for the centralization of complex cancer surgery for patients who do not receive their care at HVH.

RESUMO

INTRODUCTION: Previous studies reported that increased hospital case volume improves outcomes after esophagectomy. Yet, the standard for high and low-volume hospitals varies in the literature. This study attempts to define the relationship between hospital operative volume and 30-day post-operative outcomes of esophagectomy in the Veterans Affairs (VA) system. METHODS: This is a retrospective review of patients that underwent esophagectomy from 2008 to 2019 utilizing the Veterans Affairs Surgical Quality Improvement Program Database. Receiver operating characteristic (ROC) analysis quantified an inflection point of optimal association between 30-day morbidity and mortality by facility volume. This point was used to separate cohorts for comparison of outcomes using 1:1 propensity score matching (PSM) to account for confounding covariates. RESULTS: Two thousand two hundred and twelve esophagectomies were performed from 2008 to 2019 and ROC analysis identified an inflection point at 43 cases (4 cases/y) where bidirectional operative volume significantly affected outcomes. Subsequent PSM resulted in 1718 cases utilized for analysis (n = 859 per cohort). Facility volume ≥4 cases/y was significantly associated with decreased odds of 30-day mortality (odds ratio(OR) = 0.57; P = 0.03), shorter length of stay (median 13 versus 14 d; P = 0.04) and longer operative times (6.5 versus 6.0 h; P < 0.001). CONCLUSIONS: VA hospitals that averaged ≥4 esophagectomies/y had significantly lower rates of mortality and length of stay. This volume threshold may serve as a benchmark to determine the optimal setting for esophageal resection. However, our findings also may reflect the benefits of cumulative operating room and multidisciplinary team experience at VA centers in conjunction with dedicated surgeons. Future studies should focus on long-term outcomes after esophagectomy in relation to hospital operative volume.

RESUMO

BACKGROUND: Low operator and institutional volume are associated with poorer procedural and long-term clinical outcomes in the general population of patients treated with percutaneous coronary interventions (PCI). AIM: To assess the relationship between operator experience and procedural outcomes of patients treated with PCI and rotational atherectomy (RA). METHODS: Data for conducting the current analysis were obtained from the national registry of percutaneous coronary interventions (ORPKI) maintained in cooperation with the Association of Cardiovascular Interventions (AISN) of the Polish Cardiac Society. The study covers data from January 2014 to December 2020. RESULTS: During the investigated period, there were 162 active CathLabs, at which 747,033 PCI procedures were performed by 851 operators (377 RA operators [44.3%]). Of those, 5188 were PCI with RA procedures; average 30 ± 61 per site/7 years (Me: 3; Q1-Q3: 0-31); 6 ± 18 per operator/7 years (Me: 0; Q1-Q3: 0-3). Considering the number of RA procedures annually performed by individual operators during the analyzed 7 years, the first quartile totaled (Q1: < =2.57), the second (Q2: < =5.57), and the third (Q3: < =11.57), while the fourth quartile was (Q4: > 11.57). The maximum number of procedures was 39.86 annually per operator. We demonstrated, through a nonlinear relationship with annualized operator volume and risk-adjusted, that operators performing more PCI with RA per year (fourth quartile) have a lower number of the overall periprocedural complications (p = 0.019). CONCLUSIONS: High-volume RA operators are related to lower overall periprocedural complication occurrence in patients treated with RA in comparison to low-volume operators.

RESUMO

BACKGROUND: Medical treatment quality has been shown to be better in high volume than in low volume hospitals. However, this relationship has not yet been confirmed in abdominal cancer in Switzerland and is relevant for referral of patients and healthcare planning. Thus, the present study investigates the association between hospital volumes for surgical resections of colon, gastric, rectal, and pancreatic carcinomas and outcomes. METHODS: This retrospective analysis is based on anonymized claims data of patients with mandatory health insurance at Helsana Group, a leading health insurance in Switzerland. Outcome parameters were length of hospital stay, mortality and cost during the inpatient stay as well as at 1-year follow-up. Hospital volume information was derived from the Quality Indicators dataset provided by the Swiss Federal Office of Public Health. The impact of hospital volume on the different treatment outcomes was statistically tested using generalized estimating equations (GEE) models, taking into account the non-independence of observations from the same hospital. RESULTS: The studies included 2'859 resections in patients aged 18 years and older who were hospitalized for abdominal cancer surgery between 2014 and 2018. Colon resections were the most common procedures (n = 1'690), followed by rectal resections (n = 709). For rectal, colon and pancreatic resections, an increase in the mean number of interventions per hospital and a reduction of low volume hospitals could be observed. For the relationship between hospital volume and outcomes, we did not observe a clear dose-response relationship, as no significantly better outcomes were observed in the higher-volume category than in the lower-volume category. Even though a positive "routine effect" cannot be excluded, our results suggest that even hospitals with low volumes are able to achieve comparable treatment outcomes to larger hospitals. CONCLUSION: In summary, this study increases transparency on the relationship between hospital volume and treatment success. It shows that simple measures such as defining a minimum number of procedures only might not lead to the intended effects if other factors such as infrastructure, the operating team or aggregation level of the available data are not taken into account.

RESUMO

BACKGROUND: Pancreatic cancer remains a highly fatal disease with a 5-year overall survival of less than 10%. In seeking to improve clinical outcomes, there is ongoing debate about the weight that should be given to patient volume in centralization models. The aim of this systematic review is to examine the relationship between patient volume and clinical outcome after pancreatic resection for cancer in the contemporary literature. METHODS: The Google Scholar, PubMed, and Cochrane Library databases were systematically searched from February 2015 until June 2021 for articles reporting patient volume and outcomes after pancreatic cancer resection. RESULTS: There were 46 eligible studies over a 6-year period comprising 526,344 patients. The median defined annual patient volume thresholds varied: low-volume 0 (range 0-9), medium-volume 9 (range 3-29), high-volume 19 (range 9-97), and very-high-volume 28 (range 17-60) patients. The latter 2 were associated with a significantly lower 30-day mortality (P < .001), 90-day mortality (P < .001), overall postoperative morbidity (P = .005), failure to rescue rate (P = .006), and R0 resection rate (P = .008) compared with very-low/low-volume hospitals. Centralization was associated with lower 30-day mortality in 3 out of 5 studies, while postoperative morbidity was similar in 4 out of 4 studies. Median survival was longer in patients traveling greater distance for pancreatic resection in 2 out of 3 studies. Median and 5-year survival did not differ between urban and rural settings. CONCLUSION: The contemporary literature confirms a strong relationship between patient volume and clinical outcome for pancreatic cancer resection despite expected bias toward more complex surgery in high-volume centers. These outcomes include lower mortality, morbidity, failure-to-rescue, and positive resection margin rates.

RESUMO

In Japan, cancer care hospitals designated by the national government have a surgical volume requirement of 400 annually, which is not necessarily defined based on patient outcomes. This study aimed to estimate surgical volume thresholds that ensure optimal 3-year survival for three periods. In total, 186 965 patients who had undergone surgery for solid cancers in 66 designated cancer care hospitals in Osaka between 2004 and 2012 were examined using data from a population-based cancer registry. These hospitals were categorized by the annual surgical volume of each 50 surgeries (eg, 0-49, 50-99, and so on). Using multivariable Cox proportional hazard regression, we estimated the adjusted 3-year survival probability per surgical volume category for 2004-2006, 2007-2009, and 2010-2012. Using the joinpoint regression model that computes inflection points in a linear relationship, we estimated the points at which the trend of the association between surgical volume and survival probability changes, defining them as surgical volume thresholds. The adjusted 3-year survival ranges were 71.7%-90.0%, 68.2%-90.0%, and 79.2%-90.3% in 2004-2006, 2007-2009, and 2010-2012, respectively. The surgical volume thresholds were identified at 100-149 in 2004-2006 and 2007-2009 and 200-249 in 2010-2012. The extents of change in the adjusted 3-year survival probability per increase of 50 surgical volumes were +4.00%, +6.88%, and +1.79% points until the threshold and +0.41%, +0.30%, and +0.11% points after the threshold in 2004-2006, 2007-2009, and 2010-2012, respectively. The existing surgical volume requirements met our estimated thresholds. Surgical volume thresholds based on the association with patient survival may be used as a reference to validate the surgical volume requirement.

RESUMO

BACKGROUND: Patient-centric measures of hospital performance for transcatheter aortic valve replacement (TAVR) are needed. OBJECTIVES: This study evaluated 30-day, risk-adjusted home time as a hospital performance metric for patients who underwent TAVR. METHODS: This study identified 160,792 Medicare beneficiaries who underwent elective TAVR from 2015 to 2019. Home time was calculated for each patient as the number of days alive and spent outside the hospital, skilled nursing facility (SNF), and long-term acute care facility for 30 days after the TAVR procedure date. Correlations between risk-adjusted, 30-day home time and other metrics (30-day, risk-adjusted readmission rate [RSRR], 30-day, risk-adjusted mortality rate [RSMR], and annual TAVR volume) were estimated using Pearson's correlation. Meaningful upward or downward reclassification (≥2 quartile ranks) in hospital performance based on quartiles of risk-adjusted, 30-day home time compared with quartiles of other measures were assessed. RESULTS: Median risk-adjusted, 30-day home time was 27.4 days (interquartile range [IQR]: 26.3-28.5 days). The largest proportion of days lost from 30-day home time was hospital stay after TAVR and SNF stay. An inverse correlation was observed between hospital-level, risk-adjusted, 30-day home time and 30-day RSRR (r = -0.465; P < 0.001) and 30-day RSMR (r = -0.3996; P < 0.001). The use of the 30-day, risk-adjusted home time was associated with reclassification in hospital performance rank hospitals compared with other metrics (9.1% up-classified, 11.2% down-classified vs RSRR; 9.1% up-classified, 10.3% down-classified vs RSMR; and 20.1% up-classified, 19.3% down-classified vs annual TAVR volume). CONCLUSIONS: Risk-adjusted, 30-day home time represents a novel patient-centered performance metric for TAVR hospitals that may provide a complimentary assessment to currently used metrics.

RESUMO

INTRODUCTION: In light of current discussions about centralisation and teaching in medicine, we wanted to investigate the differences in in-hospital outcomes after surgical treatment of isolated ankle fractures, taking into account high-volume centres (HVCs) and low-volume centres (LVCs) and teaching procedures. METHODS: A retrospective analysis of malleolar fractures recorded in a National Quality Assurance Database (AQC) from the period 01-01-1998 to 31-12-2018 was carried out. Inclusion criteria were isolated, and operatively treated lateral malleolar fractures (ICD-10 Code S82.6 and corresponding procedure codes). Variables were sought in bivariate and multivariate analyses. A total of 6760 cases were included. By dividing the total cases arbitrarily in half, 12 HVCs (n = 3327, 49%) and 56 LVCs (n = 3433, 51%) were identified. RESULTS: Patients in HVCs were younger (48 vs. 50 years old), had more comorbidities (26% vs. 19%) and had more open fractures (0.48% vs. 0.15%). Open reduction and internal fixation was the most common operative treatment at HVCs and LVCs (95% vs. 98%). A more frequent use of external fixation (2.5% vs. 0.55%) was reported at HVCs. There was no difference in mortality between treatment at HVCs and LVCs. A longer hospitalisation of 7.2 ± 5 days at HVCs vs. 6.3 ± 4.8 days at LVCs was observed. In addition, a higher rate of complications of 3.2% was found at HVCs compared to 1.9% at LVCs. The frequency of teaching operations was significantly higher at HVCs (30% vs. 26%). Teaching status had no influence on mortality or complications but was associated with a prolonged length of stay and operating time. CONCLUSION: We found significant differences between HVCs and LVCs in terms of in-hospital outcomes for ankle fractures. These differences could be explained due to a more severely ill patient population and more complex (also open) fracture patterns with resulting use of external fixation and longer duration of surgery. However, structural and organisational differences, such as an extended preoperative stays at HVCs and a higher teaching rate, were also apparent. No difference in mortality could be detected.

RESUMO

BACKGROUND: Despite minimum volume recommendations, the majority of esophagectomies are performed at centers with fewer than 20 annual cases. The present study examined the impact of institutional esophagectomy volume on in-hospital mortality, complications, and resource use after esophageal resection. METHODS: The 2010-2018 Nationwide Readmissions Database was queried to identify all adult patients undergoing esophagectomy for malignancy. Hospitals were categorized as a high-volume hospital (HVH) if performing at least 20 esophagectomies annually and as a low-volume hospital (LVH) if performing fewer than 20 esophagectomies annually. Multivariable models were developed to study the impact of volume on outcomes of interest, which included in-hospital mortality, complications, duration of hospitalization, inflation adjusted costs, readmissions, and nonhome discharge. RESULTS: Of an estimated 23,176 hospitalizations, 45.6% occurred at HVHs. Incidence of esophagectomy increased significantly along with median institutional caseload over the study period, while the proportion on hospitals considered HVHs remained steady at approximately 7.4%. After adjusting for relevant patient and hospital characteristics, HVH status was associated with decreased mortality (AOR, 0.65), length of stay (ß = -1.83), pneumonia (AOR, 0.69), prolonged ventilation (AOR, 0.50), sepsis (AOR, 0.80), and tracheostomy (AOR, 0.66) but increased odds of nonhome discharge (AOR, 1.56; all P < .01), with LVH status as reference. CONCLUSIONS: Many clinical outcomes of esophagectomy are improved with no increment in costs when performed at centers with an annual caseload of at least 20, as recommended by patient advocacy organizations. These findings suggest that centralization of esophageal resections to high-volume centers may be congruent with value-based care models.

RESUMO

In small hospitals, where the majority of colectomy surgery is performed in the United States, adopting more individual ERAS components improves outcomes. The accumulation of individual ERAS components influences outcome more than an "ERAS designation" and this can be used by small hospitals to improve outcomes.

RESUMO

BACKGROUND: Little level 1 evidence exists to guide multimodality treatment in retroperitoneal soft tissue sarcoma (RPS), which may lead to significant variation in therapeutic approaches. This analysis aimed to describe national RPS treatment trends and explore potential variability among low-/high-volume hospitals (LVH/HVHs). PATIENTS AND METHODS: In total, 5992 patients who underwent resection for primary RPS were retrospectively identified in the National Cancer Database (2004-2017). Time trend analyses examined rates of multivisceral resection (MVR), radiation, and chemotherapy use. LVHs were defined as those carrying out fewer than ten resections per year (N = 5433), whereas HVHs were defined as those carrying out ten or more (N = 559). Descriptive statistics and logistic regression models compared trends between groups. RESULTS: MVR was more frequent at HVHs (63.7% versus 43.5%, p < 0.001). Use of radiation varied widely by hospital volume. HVHs more frequently employed preoperative radiation as compared with LVHs (14.7% versus 8.1%, p < 0.001). Throughout the study period, LVHs increased utilization of preoperative radiation (2.6% to 12.0%, p < 0.001) whereas rates at HVHs remained stable. Overall, LVHs utilized postoperative radiation significantly more frequently as compared with HVHs (14.7% versus 2.7%, respectively, p < 0.001). Postoperative radiation at LVHs remained stable until 2013 and sharply declined thereafter (16.7% to 6.9%, p < 0.001). Rates of postoperative radiation use at HVHs remained lower than those at LVHs at all time points. CONCLUSIONS: Strategies for resection and radiation use at LVHs have trended towards those of HVHs. Current national implementation of preoperative radiation, MVR, and chemotherapy remains heterogeneous. These findings inform future trial design and support standardization of care.

RESUMO

OBJECTIVE: To characterize the relationship between surgical volume and postoperative outcomes in congenital heart surgery, we used a national cohort to assess the costs, readmissions, and complications in children undergoing cardiac operations. STUDY DESIGN: The Nationwide Readmissions Database was used to identify pediatric patients (≤18 years) undergoing congenital cardiac surgery from 2010 to 2017. Hospitals were categorized based on deciles and tertiles of annual caseload with high-volume categorized as the highest tertile of volume. Multivariable regression models adjusting for patient and hospital characteristics were used to study the impact of volume on 30-day nonelective readmission, mortality, home discharge, and resource use. RESULTS: Of an estimated 69 448 hospitalizations included for analysis, 56 672 (82%) occurred at high-volume centers. After adjustment for key clinical factors, each decile increase in volume was associated with a 25% relative decrease in the odds of mortality, a 14% decrease in the odds of nonhome discharge, and a 4% relative decrease in the likelihood of 30-day nonelective readmission. After risk adjustment, each incremental increase in volume decile was associated with a one-half-day decrease in the hospital length of stay, but did not alter costs of the index hospitalization. However, after including all readmissions within 30 days of the index discharge, high-volume centers were associated with significantly lower costs compared with low-volume hospitals. CONCLUSIONS: Increased congenital cardiac surgery volume is associated with improved mortality, reduced duration of hospitalization, 30-day readmissions, and resource use. These findings demonstrate the inverse relationship between hospital volume and resource use and may have implications for the centralization of care for congenital cardiac surgery.

RESUMO

BACKGROUND: Laparoscopic colectomy is considered the standard of care in colon cancer treatment when appropriate expertise is available. However, guidelines do not delineate what experience is required to implement this approach safely and effectively. This study aimed to establish a data-derived, hospital-level annual volume threshold for laparoscopic colectomy at which patient outcomes are optimized. METHODS: This evaluation included 44,157 stage I to III adenocarcinoma patients aged ≥40 years who underwent laparoscopic colon resection between 2010 and 2015 within the National Cancer Database. The primary outcome was overall survival, with 30- and 90-day mortality, duration of stay, days to receipt of chemotherapy, and number of lymph nodes examined as secondary. Segmented logistic and Cox regression models were used to identify volume thresholds which optimized these outcomes. RESULTS: In hospitals performing ≥30 laparoscopic colectomies per year there were incremental improvements in overall survival for each additional resection beyond 30. Hospitals performing ≥30 procedures/year demonstrated improved 30-day mortality (1.3% vs 1.7%, P < .001), 90-day mortality (2.3% vs 2.9%, P < .001), and overall survival (84.3% vs 82.3%, P < .001). Those hospitals performing <30 procedures/year had no significant benefit in overall survival. Thresholds were not identified for any other outcomes. Results were comparable in colon cancer patients with stage IV or multiple cancers. CONCLUSION: A high-volume hospital threshold of ≥30 cases/year for laparoscopic colectomies is associated with improved patient survival and outcomes. A minimum volume standard may help providers determine which approach is most suitable for their hospital's practice as open procedures may yield better oncologic results in low volume settings.

RESUMO

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has been increasingly used to treat complex thoracic aortic pathology. In the present study, we assessed the hospital volume's effects on the outcomes of patients who had undergone TEVAR. METHODS: Patients who had undergone TEVAR from January 2015 to December 2019 were identified from the Vascular Quality Initiative database. The participating centers were stratified by volume as low-volume hospitals (LVHs) and high-volume hospitals (HVHs). We assessed the effects of hospital volume on 30-day mortality and major postoperative complications using multivariable logistic regression analysis. RESULTS: A total of 3584 TEVAR patients (1720 asymptomatic and 1864 symptomatic or ruptured) were identified at 147 centers. The median average annual number of TEVAR cases at the LVHs and HVHs was 6 and 17 cases, respectively. No significant differences were found in 30-day mortality between the LVHs and HVHs (asymptomatic, 3.7% vs 3.7% [P = .98]; symptomatic or ruptured, 9.3% vs 7.3% [P = .13]). After adjusting for multiple clinical and anatomic factors, treatment at a LVH was not associated with increased 30-day mortality (asymptomatic: odds ratio, 0.98; 95% confidence interval, 0.52-1.87; P = .96; symptomatic or ruptured: odds ratio, 1.15; 95% confidence interval, 0.75-1.77; P = .53) nor an increased risk of major complications, including renal, neurologic, cardiac, pulmonary, and femoral artery access complications (P > .05 for all). CONCLUSIONS: Using a large national database, we have demonstrated that treatment at LVHs is not associated with inferior TEVAR outcomes compared with HVHs. The technical aspect of the procedure might play a role in the similarity of outcomes across the different institutional experiences.

RESUMO

Chronic kidney disease (CKD) increases the risk of death and other poor outcomes in patients with cardiovascular diseases. This study investigated the relation between the institutional CKD percutaneous coronary intervention (PCI) volume and in-hospital clinical outcomes in patients with CKD. Among 1,199,901 patients who underwent PCI in 2014 to 2018 from the Japanese nationwide registry, we analyzed 220,509 patients with CKD. Patients were classified into quartiles (Q) according to the mean annual institutional CKD-PCI volume (Q1 <42 PCIs/year, Q2 <74 PCIs/year, Q3 <124 PCIs/year, Q4 ≥125 PCIs/year). The primary outcome was a composite of in-hospital death and periprocedural complications. The mean age of patients was 73 ± 10 years, and 36% (n = 78,332) were on dialysis. PCI was more likely to be performed with rotational atherectomy devices in high-volume institutions. Contrast volume was lower, the rate of radial access PCI was higher, and door-to-balloon time (for ST-elevation myocardial infarction) was shorter in the highest quartile institutions. Primary outcomes were observed in 6,539 patients (3.0%). The crude rate of the primary outcome was lowest in institutions with the highest PCI volume (Q1 3.4%, Q2 3.0%, Q3 3.0%, Q4 2.4%, p <0.001); higher PCI volume was associated with reduced frequency of the primary outcome (odds ratio [95% confidence interval] relative to Q1:Q2, 0.89 [0.83 to 0.96]; Q3 0.90 [0.84 to 0.97]; and Q4 0.76 [0.84 to 0.97]). In conclusion, the procedural characteristics and outcomes of PCI differed significantly by institutional volume in patients with CKD. When considering revascularization among these patients, institutional CKD-PCI volume needs to be incorporated in decision-making.

RESUMO

OBJECTIVES: To investigate volume-outcome relationships in robot-assisted radical prostatectomy (RARP) for cancer using data from the Hospital Episodes Statistics (HES) database for England. MATERIALS AND METHODS: Data for all adult, elective RPs for cancer during the period January 2013-December 2018 (inclusive) were extracted from the HES database. The HES database records data on all National Health Service (NHS) hospital admissions in England. Data were extracted for the NHS trust and surgeon undertaking the procedure, the surgical technique used (laparoscopic, open or robot-assisted), hospital length of stay (LOS), emergency readmissions, and deaths. Multilevel modelling was used to adjust for hierarchy and covariates. RESULTS: Data were available for 35 629 RPs (27 945 RARPs). The proportion of procedures conducted as RARPs increased from 53.2% in 2013 to 92.6% in 2018. For RARP, there was a significant relationship between 90-day emergency hospital readmission (primary outcome) and trust volume (odds ratio [OR] for volume decrease of 10 procedures: 0.99, 95% confidence interval [CI] 0.99-1.00; P = 0.037) and surgeon volume (OR for volume decrease of 10 procedures: 0.99, 95% CI 0.99-1.00; P = 0.013) in the previous year. From lowest to highest volume category there was a decline in the adjusted proportion of patients readmitted as an emergency at 90 days from 10.6% (0-49 procedures) to 7.0% (≥300 procedures) for trusts and from 9.4% (0-9 procedures) to 8.3% (≥100 procedures) for surgeons. LOS was also significantly associated with surgeon and trust volume, although 1-year mortality was associated with neither. CONCLUSIONS: There is evidence of a volume-outcome relationship for RARP in England and minimising low-volume RARP will improve patient outcomes. Nevertheless, the observed effect size was relatively modest, and stakeholders should be realistic when evaluating the likely impact of further centralisation at a population level.
