Centralization of Services and Reduction of Adverse Events in Pancreatic Cancer Surgery

The results of surgery for renal cell carcinoma metastases of the pancreas

BACKGROUND

Pancreatic metastases from renal cell carcinoma (RCC) are rare. This study evaluated the surgical pathology and outcomes after resection of RCC metastases to the pancreas.

MATERIAL AND METHODS

A retrospective review of from 1 January 2011 to 31 December 2021, of patients who underwent pancreatic surgery for metastases from RCC. Data were retrieved from a prospectively managed database and patient demographics, comorbidities, pathology, perioperative outcomes, and overall survival were analyzed. Median overall survival (OS) and disease-free survival (DFS) were estimated by the Kaplan-Meier method.

RESULTS

There were 25 patients (17 males, 8 females, median age 66 range 51 - 79 year), all with metachronous metastases. Median time from resection of the primary to operation for pancreatic RCC was 95.6 (12.0 - 309.7) months. Twenty-four patients were operated with intended cure (four pancreaticoduodenectomies, three total pancreatectomies, 17 distal pancreatectomies) and one patient had abortive surgery due to dissemination. Postoperative surgical complications occurred in nine patients (36%), and one patient died during hospital stay. Eight patients (33.3%) developed exocrine and/or endocrine insufficiency after pancreatic resection. Fifteen patients (60%) had recurrence 21.7 (4.9 - 61.6) months after pancreatic operation. Five patients (25%) died from RCC during follow-up 46.3 (25.6 - 134.8) months after pancreatic resection. Five-year OS and DFS were83.6% and 32.3%, respectively. Median OS after pancreatic surgery was 134.8 months, independent of resection of previous extrapancreatic metastases.

CONCLUSIONS

Pancreatic resection for metastases from RCC offers favorable prognosis with a curative potential and should be considered a valuable treatment option even in the era of novel targeted treatment.

Implications of the interaction between travel burden and area deprivation for patients with pancreatic cancer

INTRODUCTION

Fragmentation of care and distance traveled are classically surrogates for poor access to care, but little is known about how social determinants of health interact with travel burden to affect survival for patients with pancreatic cancer (PC). We sought to characterize the individual and composite impact of these factors.

METHODS

20769 patients treated for PC between 2005 and 2019 in the Texas Cancer Registry were included. The Area Deprivation Index and Poverty Index were used to quantify social determinants of health. Survival analyses were performed at 2 years as well as subgroup analysis on patients with the greatest travel burden.

RESULTS

Improved survival was associated with FC (HR 0.74, CI 0.71-0.77) and distance from an accredited cancer center (Quartile 4 HR 0.90, CI 0.81-1.00). High ADI led to worse outcomes while low ADI led to improved outcomes with increasing travel burden.

CONCLUSIONS

This data shows a complex relationship between travel burden and survival for patients with pancreatic cancer where stratifying by area deprivation reveals divergent outcomes and the potential to exacerbate disparities.

Incomplete patient information exchange and unnecessary repeat diagnostics during oncological referrals in the Netherlands: exploring the role of information exchange

Data management in transmural care is complex. Without digital innovations like Health Information Exchange (HIE), patient information is often dispersed and inaccessible across health information systems between hospitals. The extent of information loss and consequences remain unclear. We aimed to quantify patient information availability of referred oncological patients and to assess its impact on unnecessary repeat diagnostics by observing all oncological multidisciplinary team meetings (MDTs) in a tertiary hospital. During 84 multidisciplinary team meetings, 165 patients were included. Complete patient information was provided in 17.6% (29/165, CI = 12.3-24.4) of patients. Diagnostic imaging was shared completely in 52.5% (74/141, CI = 43.9-60.9), imaging reports in 77.5% (100/129, CI = 69.2-84.2), laboratory results in 55.2% (91/165, CI = 47.2-62.8), ancillary test reports in 58.0% (29/50, CI = 43.3-71.5), and pathology reports in 60.0% (57/95, CI = 49.4-69.8). A total of 266 tests were performed additionally, with the main motivation not previously performed followed by inconclusive or insufficient quality of previous tests. Diagnostics were repeated unnecessarily in 15.8% (26/165, CI = 10.7-22.4) of patients. In conclusion, patient information was provided incompletely in majority of referrals discussed in oncological multidisciplinary team meetings and led to unnecessary repeat diagnostics in a small number of patients. Additional research is needed to determine the benefit of Health Information Exchange to improve data transfer in oncological care.

Centralisation of surgery for complex cancer diseases: A scoping review of the evidence base on pancreatic cancer

BACKGROUND

Centralisation of cancer surgery is a commonly applied healthcare strategy worldwide. This study aimed to detail the design of centralisation policies, to shed light on the implications of such policies in real practice and to describe the different perspectives taken to deal with difficulties that emerged, taking pancreatic cancer as an example of a complex cancer disease requiring surgery.

METHODOLOGY

A scoping review was conducted using the MEDLINE database. We systematically searched for eligible studies published between January 2000 and December 2018.

RESULTS

In the 33 included studies, centralisation of pancreatic cancer surgery was implemented through three different models: designated hospitals, definition of minimum volumes per provider, and/or recommendations included in protocols and national guidelines. The presence of highly advanced technology and infrastructures, the availability of extensive service coverage and advanced care processes based on expert multidisciplinary teams, and higher caseloads were identified as key components of centralisation policy.

CONCLUSIONS

Centralisation models for pancreatic cancer surgery showed that having expert centres where the care process is comprehensively guided is a foundational policy approach. External quality assessment and the accreditation of centres and professionals performing complex surgical procedures are levers that may positively impact the effectiveness of the measure. POLICY SUMMARY: while we found different experiences and three models of centralisation, all of them were guided by the will to positively impact on pancreatic cancer patients' access to expert care. Clinical research might be able to make progress in the coming years and perhaps contribute to reversing a critical situation of high mortality and growing incidence. However, policymakers must optimise health system responses considering current resources, as suggested by the recommendations proposed in the framework of the EU initiative Bratislava Statement for pancreatic cancer care.

Trends in the Geospatial Distribution of Inpatient Adult Surgical Services across the United States

OBJECTIVE

The aim of this study was to define trends in the geographic distribution of surgical services in the United States to assess possible geographic barriers and disparities in access to surgical care.

SUMMARY BACKGROUND DATA

Despite the increased need and utilization of surgical procedures, Americans often face challenges in gaining access to health care that may be exacerbated by the closure and consolidation of hospitals. Although access to surgical care has been evaluated relative to the role of insurance, race, and health literacy/education, the relationship of geography and travel distance to access has not been well studied.

METHODS

The 2005 and 2015 American Hospital Association annual survey was used to identify hospitals with surgical capacity; the data were merged with 2010 Census Bureau data to identify the distribution of the US population relative to hospital location, and geospatial analysis tools were used to examine a service area of real driving time surrounding each hospital.

RESULTS

Although the number of hospitals that provided surgical services slightly decreased over the time periods examined (2005, n = 3791; 2015, n = 3391; P<0.001), the number of major surgery hospitals increased from 2005 (n = 539) to 2015 (n = 749) (P<0.001). The geographic location of hospitals that provided surgical services changed over time. Specifically, although in 2005 852 hospitals were located in a rural area, that number had decreased to 679 by 2015 (P<0.001). Of particular note, from 2005 to 2015 there was an 82% increase in the number of people who lived further than 60 minutes from any hospital (P<0.001). However, the number of people who lived further than 60 minutes from a major surgery hospital decreased (P<0.001).

CONCLUSIONS

Although the number of rural hospitals decreased over the last decade, the number of large, academic medical centers has increased; in turn, there has been an almost doubling in the number of people who live outside a 60-minute driving range to a hospital capable of performing surgery.

Traveling for Pancreatic Cancer Care Is Worth the Trip

BACKGROUND

Centralized care for patients with pancreatic cancer is associated with longer survival. We hypothesized that increased travel distance from home is associated with increased survival for pancreatic cancer patients.

METHODS

The National Cancer Database user file for all pancreatic cancer patients was investigated from 2004 through 2015. Distance from the patients' zip code to the treating facility was determined. Survival was investigated using the Kaplan-Meier method. Cox hazard ratios (CoxHRs) were determined based on stage of disease, distance traveled for care, and clinical factors.

RESULTS

340 780 patients were identified. In the average age of 68 ± 12 years, 51% were male and 83% were Caucasian. For all stages of cancer, longer survival was associated with traveling farther (P < .001). The survival advantage was longer for Caucasians than African Americans (3.7 months vs. 2.6 months, P < .001) Travel was associated with a 13% decrease in risk of death (P < .001). Even controlling for the pathologic stage, traveling farther was associated with decreased risk of death (CoxHR = .91, P < .001).

DISCUSSION

Traveling for care is associated with improved survival for pancreatic cancer patients. While a selection bias may exist, the fact that all stages of patients investigated benefited suggests that this is a real phenomenon.

Trends in the Geospatial Distribution of Adult Inpatient Surgical Cancer Care Across the United States

INTRODUCTION

The relationship and trends of geography and travel distance to access surgical cancer care has been poorly characterized. The objective of the study was to define the geographic distribution of access to hospital-based operative cancer care across the USA.

METHODS

A cohort analysis was performed using the 2005 and 2015 American Hospital Association Annual Survey, Census Bureau Data for 2010, and the American Community Survey 5-year estimates for 2011 to 2016.

RESULTS

The number of hospitals that provided surgical services with an approved American College of Surgeons (ACS) cancer program slightly increased over the time periods examined (2005, n = 1203 vs. 2015, n = 1284; p = 0.7210). Based on geospatial analysis, 18,214,994 (5.9%) people lived more than 60 min from a hospital with a cancer program in 2005 compared with 34,630,516 (11.2%) by 2015. Communities within a 60-min drive time were more likely to be composed of individuals who completed high school (85.9% vs. 84.2%), were employed (62.7% vs. 57.1%), had a higher median household income ($67.4 k vs. $53.2 k), and lived within states that had expanded Medicaid (62.5% vs. 48.9%) (all p < 0.0001). In contrast, communities outside of a 60-min drive time had a greater proportion of individuals below the federal poverty level (18.3% vs. 16.5%; p < 0.0001).

CONCLUSIONS

While the number of hospitals with ACS approved cancer program designation increased over the last decade, the number of people living greater than 60 min from an approved cancer programs nearly doubled. These data highlight worrisome geospatial trends that may make access to cancer care for certain patient populations increasingly challenging.

Accessing surgical care for pancreaticoduodenectomy: Patient variation in travel distance and choice to bypass hospitals to reach higher volume centers

BACKGROUND

While better outcomes at high-volume surgical centers have driven regionalization of complex surgical care, access to high-volume centers often requires travel over longer distances. We sought to evaluate travel patterns of patients undergoing pancreaticoduodenectomy (PD) for pancreatic cancer to assess willingness of patients to travel for surgical care.

METHODS

The California Office of Statewide Health Planning database was used to identify patients who underwent PD between 2005 and 2016. Total distance traveled, as well as whether a patient bypassed the nearest hospital that performed PD to get to a higher-volume center was assessed. Multivariate analyses were used to identify factors associated with bypassing a local hospital for a higher-volume center.

RESULTS

Among 23 014 patients who underwent PD, individuals traveled a median distance of 18.0 miles to get to a hospital that performed PD. The overwhelming majority (84%) of patients bypassed the nearest providing hospital and traveled a median additional 16.6 miles to their destination hospital. Among patients who bypassed the nearest hospital, 13,269 (68.6%) did so for a high-volume destination hospital. Specifically, average annual PD volume at the nearest "bypassed" vs final destination hospital was 29.6 vs 56 cases, respectively. Outcomes at bypassed vs destination hospitals varied (incidence of complications: 39.2% vs 32.4%; failure-to-rescue: 14.5% vs 9.1%). PD at a high-volume center was associated with lower mortality (OR = 0.46 95% CI, 0.22-0.95). High-volume PD ( > 20 cases) was predictive of hospital bypass (OR = 3.8 95% CI, 3.3-4.4). Among patients who had surgery at a low-volume center, nearly 20% bypassed a high-volume hospital in route. Furthermore, among patients who did not bypass a high-volume hospital, one-third would have needed to travel only an additional 30 miles or less to reach the nearest high-volume hospital.

CONCLUSION

Most patients undergoing PD bypassed the nearest providing hospital to seek care at a higher-volume hospital. While these data reflect increased regionalization of complex surgical care, nearly 1 in 5 patients still underwent PD at a low-volume center.

Centralization of Pancreatic Surgery in Europe

BACKGROUND

The objective of this article is a review and an analysis of the current state of centralization of pancreatic surgery in Europe. Numerous recent publications demonstrate higher postoperative in-hospital mortality rates in low-volume clinics after pancreatic resection than previously assumed due to their not publishing significantly worse outcomes when compared to high-volume centres. Although the benefits of centralization of pancreatic surgery in high-volume centres have been demonstrated in many studies, numerous countries have so far failed to establish centralization in their respective health care systems.

METHODS

A systematic literature search of the Medline database for studies concerning centralization of pancreatic surgery in Europe was conducted. The studies were reviewed independently for previously defined inclusion and exclusion criteria. We included 14 studies with a total of 117,634 patients. All data were extracted from or provided by health insurance company or governmental registry databases.

RESULTS

Thirteen out of the 14 studies demonstrate an improvement in their respective outcome related to volume. Twelve studies showed a significantly lower postoperative mortality rate in the highest annual volume group in comparison to overall postoperative mortality rate in the whole patient cohort.

CONCLUSION

As the available data indicate, most European countries have so far failed to establish centralization of pancreatic surgery to high-volume centres due to numerous reasons. Considering a plateau in survival rates of patients undergoing treatment for pancreatic cancer in Europe during the last 15 years, this review enforces the worldwide plea for centralization to lower post-operative mortality after pancreatic surgery.

Is Centralization Needed for Patients Undergoing Distal Pancreatectomy?: A Nationwide Study of 3314 Patients

OBJECTIVE

The centralization of complex surgical procedures is associated with better postoperative outcomes. However, little is known about the impact of hospital volume on the outcome after distal pancreatectomy.

METHODS

Using the French national hospital discharge database, we identified all patients having undergone distal pancreatectomy in France between 2012 and 2015. A spline model was applied to determine the caseload cut-off in annual distal pancreatectomy that influenced 90-day postoperative mortality.

RESULTS

A total of 3314 patients were identified. Use of a spline model did not reveal a cut-off in the annual distal pancreatectomy caseload. By taking the median number of distal pancreatectomy (n = 5) and the third quartile (n = 15), we stratified centers into low, intermediate, and high hospital volume groups. The overall postoperative mortality rate was 3.0% and did not differ significantly between these groups. In a multivariable analysis, age, Charlson comorbidity score, septic complications, hemorrhage, shock, and reoperation were independently associated with a greater overall risk of death. However, hospital volume had no impact on mortality after distal pancreatectomy (odds ratio, 0.954; 95% confidence interval, 0.552-1.651, P = 0.867).

CONCLUSIONS

Hospital volume does not seem to influence mortality after distal pancreatectomy in France, and centralization may not necessarily improve outcomes.

Geographic Distribution of Adult Inpatient Surgery Capability in the USA

INTRODUCTION

Access to timely, quality, and affordable surgical services is an important component of health care systems. A better understanding of the geographic distribution of surgical services in the USA may help identify disparities in access to surgery.

METHODS

Using the 2015 American Hospital Association Annual Survey, the 2010 Census Bureau Data, and the American Community Survey 5-year estimates from 2011 to 2016, all hospitals with surgical capabilities were geocoded with 30 straight-line mile service areas around each hospital using geospatial analysis. Major surgical hospitals were defined as meeting three of the four following criteria: bed size ≥ 45, ≥ 8600 operations per year, ≥ 12 operating rooms, and academic medical center. The distribution of the US population based on proximity to a hospital capable of performing adult inpatient surgery and a major surgical hospital was then analyzed and compared.

RESULTS

Overall, 3409 hospitals were identified that had the capacity to perform adult inpatient surgery of which 1373 were defined as major surgical hospitals. Based on geospatial analysis, 10% of the US population was found to reside outside of a linear 30-mile radius of a surgical hospital. Younger age (OR 0.97, CI 0.96-0.97), female sex (OR 4.6, CI 4.3-5), African-American race (OR = 5.4, CI 4.7-6.2), Hispanic/Latino race (OR 5.5, CI 4.8-6.3), having completed high school or greater (OR = 3.6, CI 3-4.2), being employed (OR 4.8, CI 4.6-4.9), and having any type of health insurance were significantly associated with living in a service area.

CONCLUSION

A significant proportion of the US population lives greater than 30 straight-line miles from a major surgical hospital. Common demographic and socioeconomic factors highlight disparities in access to surgical care.

Resection of pancreatic cancer in Europe and USA: an international large-scale study highlighting large variations

OBJECTIVE

Resection can potentially cure resectable pancreatic cancer (PaC) and significantly prolong survival in some patients. This large-scale international study aimed to investigate variations in resection for PaC in Europe and USA and determinants for its utilisation.

DESIGN

Data from six European population-based cancer registries and the US Surveillance, Epidemiology, and End Results Program database during 2003-2016 were analysed. Age-standardised resection rates for overall and stage I-II PaCs were computed. Associations between resection and demographic and clinical parameters were assessed using multivariable logistic regression models.

RESULTS

A total of 153 698 records were analysed. In population-based registries in 2012-2014, resection rates ranged from 13.2% (Estonia) to 21.2% (Slovenia) overall and from 34.8% (Norway) to 68.7% (Denmark) for stage I-II tumours, with great international variations. During 2003-2014, resection rates only increased in USA, the Netherlands and Denmark. Resection was significantly less frequently performed with more advanced tumour stage (ORs for stage III and IV versus stage I-II tumours: 0.05-0.18 and 0.01-0.06 across countries) and increasing age (ORs for patients 70-79 and ≥80 versus those <60 years: 0.37-0.63 and 0.03-0.16 across countries). Patients with advanced-stage tumours (stage III-IV: 63.8%-81.2%) and at older ages (≥70 years: 52.6%-59.5%) receiving less frequently resection comprised the majority of diagnosed cases. Patient performance status, tumour location and size were also associated with resection application.

CONCLUSION

Rates of PaC resection remain low in Europe and USA with great international variations. Further studies are warranted to explore reasons for these variations.

Emerging U.S. National Trends in the Treatment of Pediatric Supracondylar Humeral Fractures

BACKGROUND

Understanding national trends in the treatment of pediatric supracondylar humeral fractures will provide important insight into variations in regional treatment and identify areas for improving value and quality in care delivery in the U.S.

METHODS

U.S. national trends in the treatment of supracondylar humeral fractures were evaluated through query of the Humana (2007 to 2014) and ING (2007 to 2011) administrative claims databases. Geographic variation and changes in surgical and transfer rates over time were further explored through the Nationwide Emergency Department Sample (NEDS) database (2006 to 2011). Hospital characteristics impacting treatment decisions were identified.

RESULTS

A total of 29,642 pediatric patients with supracondylar humeral fractures were identified in the administrative claims databases and a projected 63,348 encounters for supracondylar humeral fracture were identified in the NEDS database. The majority of the patients (76.1%; 22,563 of 29,642) were treated definitively with cast immobilization. Operative treatment was performed in 23.9% of the patients (7,079 of 29,642), with no change observed in the operative rate over time (p = 0.055). Of patients undergoing operative treatment, closed reduction and percutaneous pinning (CRPP) was performed in 87.3%, with a significant increase noted in the rate of CRPP over time (p = 0.0001); open reduction was performed in 12.7%, with a significant decrease noted in the rate of open reduction over time (p < 0.0001). Regional surgical rates generally showed significant variation from 2006 to 2010, followed by a convergence in the surgical rate among all geographic regions in 2011. These trends occurred simultaneous to a significant increase in transfer rates nationwide, from 5.6% in 2006 to 9.1% in 2011 (p = 0.0011). Transfer rates were significantly higher (p < 0.0001) for nontrauma, nonteaching, and nonmetropolitan centers while surgical rates were significantly higher (p < 0.0001) for trauma, teaching, and metropolitan centers when rates were analyzed by hospital designation.

CONCLUSIONS

Operative treatment was performed in 24% of pediatric patients with supracondylar humeral fractures from 2007 to 2014. There was a convergence of surgical rates across geographic regions, suggesting that a "standard of care" in the treatment of supracondylar humeral fractures is being established nationally.

CLINICAL RELEVANCE

Cases of pediatric supracondylar humeral fracture are increasingly being transferred to and, when managed surgically, receiving care at metropolitan facilities designated as trauma centers or teaching hospitals, with a corresponding decrease observed in the rate of open reduction. The optimization of nationwide referral and treatment patterns may improve value in care delivery.

Variation in survival after surgery for peri-ampullary cancer in a regional cancer network

BACKGROUND

Centralisation of specialist surgical services requires that patients are referred to a regional centre for surgery. This process may disadvantage patients who live far from the regional centre or are referred from other hospitals by making referral less likely and by delaying treatment, thereby allowing tumour progression. The aim of this study is to explore the outcome of surgery for peri-ampullary cancer (PC) with respect to referring hospital and travel distance for treatment within a network served by five hospitals.

METHODS

Review of a unit database was undertaken of patients undergoing surgery for PC between January 2006 and May 2014.

RESULTS

394 patients were studied. Although both the median travel distance for patients from the five hospitals (10.8, 86, 78.8, 54.7 and 89.2 km) (p < 0.05), and the annual operation rate for PC (2.99, 3.29, 2.13, 3.32 and 3.07 per 100,000) (p = 0.044) were significantly different, no correlation was noted between patient travel distance and population operation rate at each hospital. No difference was noted between patients from each hospital in terms of resection completion rate or pathological stage of the resected tumours. The median survival after diagnosis for patients referred from different hospitals ranged from 1.2 to 1.7 years and regression analysis revealed that increased travel distance to the regional centre was associated with a small survival advantage.

CONCLUSION

Although variation in the provision and outcome of surgery for PC between regional hospitals is noted, this is not adversely affected by geographical isolation from the regional centre.

Pediatric distal humeral fractures and complications of treatment in Finland: a review of compensation claims from 1990 through 2010

BACKGROUND

The distal part of the humerus is the second most common fracture location in children. Complications are more common than with other pediatric fractures and are mostly related to inappropriate diagnosis and treatment.

METHODS

On the basis of data from 1990 through 2010 in the national registry of inpatient care treatment in Finland, we calculated the number of children less than seventeen years of age who were treated under anesthesia for a distal humeral fracture (reduction with or without internal fixation) and the number of treatment institutions. We analyzed compensation claims concerning the treatment of these fractures that were received by the Patient Insurance Centre. The risk of a complication of treatment and the number of avoidable complications of treatment were assessed.

RESULTS

A total of 7909 children underwent a procedure under anesthesia to treat a distal humeral fracture. Claims were filed for 117 patients (118 fractures, including seventy-four supracondylar, nineteen epicondylar, nineteen condylar, and six T-type), and compensation was granted for eighty-three (71%) of the patients. Deformity (forty-nine), delayed treatment (twenty), nerve injury (seventeen), and infection (seven) were the most common reasons for compensation. On reevaluation of the claims, ninety patients were assessed as having had complications of treatment. In our opinion, complications could have been avoided for eighty-six (96%) of these patients.

CONCLUSIONS

We believe that improving the quality of primary assessment and operative technique would decrease the number of complications in the treatment of pediatric distal humeral fractures. Centralizing operative treatment to tertiary hospitals should be considered.
