    Introduction High hospital case volumes are associated with improved treatment outcomes for numerous diseases. We assessed the association between academic non-profit hospital case volume and survival of adult glioblastoma patients. Methods From the nationwide Finnish Cancer Registry, we identified all adult (>= 18 years) patients with histopathological diagnoses of glioblastoma from 2000 to 2013. Five university hospitals (treating all glioblastoma patients in Finland) were classified as high-volume (one hospital), middle-volume (one hospital), and low-volume (three hospitals) based on their annual numbers of cases. We estimated one-year survival rates, estimated median overall survival times, and compared relative excess risk (RER) of death between high, middle, and low-volume hospitals. Results A total of 2,045 patients were included. The mean numbers of annually treated patients were 54, 40, and 17 in the high, middle, and low-volume hospitals, respectively. One-year survival rates and median survival times were higher and longer in the high-volume (39%, 9.3 months) and medium-volume (38%, 8.9 months) hospitals than in the low-volume (32%, 7.8 months) hospitals. RER of death was higher in the low-volume hospitals than in the high-volume hospital (RER = 1.19, 95% CI 1.07-1.32, p = 0.002). There was no difference in RER of death between the high-volume and medium-volume hospitals (p = 0.690). Conclusion Higher glioblastoma case volumes were associated with improved survival. Future studies should assess whether this association is due to differences in patient-specific factors or treatment quality.

    Objective: As open abdominal aortic aneurysm (AAA) repair (OAR) rates decline in the endovascular era, the endorsement of minimum volume thresholds for OAR is increasingly controversial, as this may affect credentialing and training. The purpose of this analysis was to identify an optimal centre volume threshold that is associated with the most significant mortality reduction after OAR, and to determine how this reflects contemporary practice. Methods: This was an observational study of OARs performed in 11 countries (2010 - 2016) within the International Consortium of Vascular Registry database (n = 178 302). The primary endpoint was post-operative in hospital mortality. Two different methodologies (area under the receiving operating curve optimisation and Markov chain Monte Carlo procedure) were used to determine the optimal centre volume threshold associated with the most significant mortality improvement. Results: In total, 154 912 (86.9%) intact and 23 390 (13.1%) ruptured AAAs were analysed. The majority (63.1%; n = 112 557) underwent endovascular repair (EVAR) (OAR 36.9%; n = 65 745). A significant inverse relationship between increasing centre volume and lower peri-operative mortality after intact and ruptured OAR was evident (p < .001) but not with EVAR. An annual centre volume of between 13 and 16 procedures per year was associated with the most significant mortality reduction after intact OAR (adjusted predicted mortality < 13 procedures/year 4.6% [95% confidence interval 4.0% - 5.2%] vs. = 13 procedures/year 3.1% [95% CI 2.8% - 3.5%]). With the increasing adoption of EVAR, the mean number of OARs per centre (intact + ruptured) decreased significantly (2010 - 2013 = 35.7; 2014 - 2016 = 29.8; p < .001). Only 23% of centres (n = 240/1 065) met the >= 13 procedures/year volume threshold, with significant variation between nations (Germany 11%; Denmark 100%). Conclusion: An annual centre volume of 13 - 16 OARs per year is the optimal threshold associated with the greatest mortality risk reduction after treatment of intact AAA. However, in the current endovascular era, achieving this threshold requires significant re-organisation of OAR practice delivery in many countries, and would affect provision of non-elective aortic services. Low volume centres continuing to offer OAR should aim to achieve mortality results equivalent to the high volume institution benchmark, using validated data from quality registries to track outcomes.

    Background: Centralization of pancreatic surgery has proceeded in the last few years in many countries. However, information on the effect of hospital volume specifically on distal pancreatic resections (DP) is lacking. Aim: To investigate the effect of hospital volume on postoperative complications in DP patients in Finland. Methods: All DP performed in Finland during the period 2012-2014 were analyzed, information having been retrieved from the appropriate national registers. Hospital volumes, postoperative pancreatic fistulae (POPF) and overall complications were graded. High volume centre (HVC) was defined as performing > 10 DPs, median volume centre (MVC) 4-9 DPs and low volume centre (LVC) fewer than 4 DP annually. Results: A total of 194 DPs were performed at 18 different hospitals. Of these 42% (81) were performed in HVCs (2 hospitals), 43% (84) in MVCs (6 hospitals) and the remaining 15% (29) in LVCs (10 hospitals). Patient demographics did not differ between the hospital volume groups. The overall rate of clinically relevant POPF, Clavien-Dindo grade 3-5 complications, and 90-day mortality showed no significant differences between the different hospital volumes. Grade C POPF was found more often in LVCs, being 1.2% in HVCs, 0% in MCVs and 6.9% in LVCs, p = 0.030. More reoperations were performed in LVCs (10.3%) than in HVCs (1.2%) or MVCs (1.2%); p = 0.025. Conclusions: Even though the rate of postoperative complications after DP is not affected by hospital volume, reoperations were performed ten times more often in the low-volume centres. Optimal management of postoperative complications may favour centralization not only of PD, but also of DP. (C) 2018 IAP and EPC. Published by Elsevier B.V. All rights reserved.

    Abstract Abdominal aortic aneurysm (AAA) is a relatively common and potentially fatal disease. The management of AAA has undergone extensive changes in the last two decades. High quality vascular surgical registries were established early and have been found to be instrumental in the evaluation and monitoring of these changes, most notably the wide implementation of minimally invasive endovascular surgical technology. Trends over the years showed the increased use of endovascular aneurysm repair (EVAR) over open repair, the decreasing perioperative adverse outcomes and the early survival advantage of EVAR. Also, data from the early EVAR years changed the views on endoleak management and showed the importance of tracking the implementation of new techniques. Registry data complemented the randomized trials performed in aortic surgery by showing the high rate of laparotomy related reinterventions after open repair. Also, they are an essential tool for the understanding of outcomes in a broad patient population, evaluating the generalizability of findings from randomized trials and analyzing changes over time. By using large scale data over longer periods of time, the importance of centralization of care to high-volume centers was shown, particularly for open repair. Additionally, large-scale databases can offer an opportunity to assess practice and outcomes in patient subgroups (e.g. treatment of AAA in women and the elderly) as well as in rare aortic pathologies. In this review article, we point out the most important paradigm shifts in AAA management based on vascular registry data.

    Objectives: Our aim was to demonstrate the influence of increased number of low-risk deliveries on obstetric and neonatal outcome. Study design: The study hospital was Katiloopisto Maternity Hospital in Helsinki. Simultaneously, we studied all three delivery units in the Helsinki region in the population-based analysis. The study population was singleton hospital deliveries occurring between 2011 and 2012, and 2014-2015. The study hospital included 11 237 and 15 637 births and the population-based group included 28 950 and 27 979 births. We compared outcome measures in different periods by calculating adjusted odds ratios (AOR). Main outcome measures were induced delivery, mode of delivery, third or fourth degree perinea, tear, Apgar score at five minutes 7 days, and perinatal death. Results: In the study hospital, induction rate increased from 22.4% to 24.8% (AOR 1.06, 95% CI; 1.00-1.12) while in the population-based analysis the rate decreased from 22.2% to 21.5% (AOR 0.96, 95% CI; 0.92-1.00). Percentage of neonatal transfers, low Apgar scores, and severe perineal tears increased both in study hospital and in population-based group. Changes in operative delivery rate and other adverse perinatal outcomes were statistically insignificant. Conclusions: Increasing the volume of a delivery unit does not compromise maternal or neonatal outcome. Specific characteristics of a delivery unit affect the volume outcome association.

    Background and objectives: This study aims to clarify quality of breast cancer surgery in population-based setting. We aim to elucidate factors influencing waiting periods, and to evaluate the effect of hospital volume on surgical treatment policies. Special interest was given to diagnostic and surgical processes and their impact on waiting times. Methods: All 1307 patients having primary breast cancer surgery at the Helsinki and Uusimaa Hospital District during 2010 were included in this retrospective study. Results: Median waiting time for primary surgery was 24 days and significantly affected by additional imaging and diagnostic biopsies as well as hospital volume. Final rate of breast conserving surgery was surprisingly low, 51%, not affected by hospital volume, p = 0.781. Oncoplastic resection and immediate breast reconstruction (IBR) were performed more often in high volume units, p <0.001. Quality of axillary surgery varied with unit size. Multiple operations, IBR and high volume unit were factors prolonging initiation of adjuvant treatment. Conclusion: Quality of preoperative diagnostics play a crucial role in minimizing the need of repeated imaging and biopsies as well as multiple operations. Positive impact of high-volume hospitals becomes evident when analyzing procedures requiring advanced surgical techniques. High-volume hospitals achieved better quality in axillary surgery.

    Purpose of ReviewThe concept of value-based health care (VBHC) was articulated more than a decade ago. However, its clinical implementation remains an on-going process and a particularly demanding one for the domain of head and neck cancer (HNC). These cancers often present with fast growing tumors in functionally and cosmetically sensitive sites and afflict patients with differing circumstances and comorbidity. Moreover, the various treatment modalities and protocols have different effects on functional outcomes. Hence, the interpretation of what constitutes VBHC in head and neck oncology remains challenging.Recent FindingsThis monograph reviews developments in specific aspects of VBHC for HNC patients, including establishment of registries and quality indices (such as infrastructure, process, and outcome indicators). It emphasizes the importance of the multidisciplinary team, "time to treatment intervals," and adherence to guidelines. The discussion addresses major indicators including survival, quality of life and functional outcomes, and adverse events. Also, strengths and weaknesses of nomograms, prognostic and decision models, and variation of care warrant attention.SummaryHealth care professionals, together with patients, must properly define quality and relevant outcomes, both for the individual patient as well as the HNC population. It is essential to capture and organize the relevant data so that they can be analyzed and the results used to improve both outcomes and value.
