BJS Open 2022; 6:6758035. [PMID: 36218348 PMCID: PMC9552551 DOI: 10.1093/bjsopen/zrac109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 07/27/2022] [Accepted: 08/01/2022] [Indexed: 11/12/2022] Open
Abstract
Background The aim of this study was to evaluate the impact of all minor and major complications on treatment-related healthcare costs in patients who undergo cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of colorectal peritoneal metastases (PMs). Method Patients with histologically proven colorectal PMs who underwent CRS + HIPEC from March 2006 to October 2019 in a tertiary referral centre were retrospectively identified from a prospectively maintained database. Patients were divided into six subgroups according to the severity of the complications, which were scored using the comprehensive complication index (CCI) (CCI 0–9.9, CCI 10–19.9, CCI 20–29.9, CCI 30–39.9, CCI 40–49.9, and CCI 50 or higher). Treatment-related healthcare costs up to 1 year after CRS + HIPEC were obtained from the financial department. Differences in costs and survival outcomes were compared using the chi-squared test and Kruskal–Wallis H test. Results A total of 142 patients were included (CCI 0–9.9, 53 patients; CCI 10–19.9, 0 patients; CCI 20–29.9, 45 patients; CCI 30–39.9, 14 patients; CCI 40–49, 9 patients; and CCI 50 or higher, 21 patients). Median (interquartile range) treatment-related healthcare costs increased significantly and exponentially for the CCI 30–39, CCI 40–49, and CCI 50 or higher groups (€48 993 (€44 262–€84 805); €57 167 (€43 047–€67 591); and €82 219 (€55 487–€145 314) respectively) compared with those for the CCI 0–9.9 and CCI 20–29.9 groups (€33 856 (€24 433–€40 779) and €40 621 (€31 501–€58 761) respectively, P < 0.010). Conclusion Treatment-related healthcare costs increase exponentially as more complications develop among patients who undergo CRS + HIPEC for the treatment of colorectal PMs. Anastomotic leakages after CRS + HIPEC lead to an increase of 295 per cent of treatment-related healthcare costs.

The Costs of Complications and Unplanned Readmissions after Pancreatoduodenectomy for Pancreatic and Periampullary Tumors: Results from a Single Academic Center. Cancers (Basel) 2021; 13:cancers13246271. [PMID: 34944890 PMCID: PMC8699101 DOI: 10.3390/cancers13246271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 11/29/2021] [Accepted: 12/07/2021] [Indexed: 11/26/2022] Open
Abstract
Simple Summary Complications lead to unplanned readmissions (UR) and are reported to be associated with a two- to threefold increase in hospital admission costs. Since healthcare costs are increasing worldwide, cost containment is the major challenge for future healthcare. In the literature, there are only a few studies that analysed hospital costs after pancreatoduodenectomy (PD). In this study, we aimed to create an understanding of the costs of complications and UR in patients who underwent a PD. Abstract Background/Objectives: Complications after pancreatoduodenectomy (PD) lead to unplanned readmissions (UR), with a two- to threefold increase in admission costs. In this study, we aimed to create an understanding of the costs of complications and UR in this patient group. Furthermore, we aimed to generate a detailed cost overview that can be used to build a theoretical model to calculate the cost efficacy for prehabilitation. Methods: A retrospective cohort analysis was performed using the Dutch Pancreatic Cancer Audit (DPCA) database of patients who underwent a PD at our institute between 2013 and 2017. The total costs of the index hospital admission and UR related to the PD were collected. Results: Of the 160 patients; 35 patients (22%) had an uncomplicated course; 87 patients (54%) had minor complications, and 38 patients (24%) had severe complications. Median costs for an uncomplicated course were EUR 25.682, and for a complicated course, EUR 32.958 (p = 0.001). The median costs for minor complications were EUR 30.316, and for major complications, EUR 42.664 (p = 0.001). Costs were related to the Comprehensive Complication Index (CCI). The median costs of patients with one or more UR were EUR 41.199. Conclusions: Complications after PD led to a EUR 4.634–EUR 16.982 (18–66%) increase in hospital costs. A UR led to a cost increase of EUR 12.567 (44%). Since hospital costs are directly related to the CCI, reduction in complications will lead to cost-effectiveness.

Does the meld system provide equal access to liver transplantation for patients with different ABO blood groups? Transpl Int 2017; 29:883-9. [PMID: 26987934 DOI: 10.1111/tri.12774] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2015] [Revised: 12/01/2015] [Accepted: 02/29/2016] [Indexed: 12/31/2022]
Abstract
This study investigates the relationship between blood group and waiting time until transplantation or death on the waiting list. All patients listed for liver transplantation in the Netherlands between 15 December 2006 and 31 December 2012, were included. Study variables were gender, age, year of listing, diagnosis, previous transplantations, blood group, urgency, and MELD score. Using a competing risks analysis, separate cumulative incidence curves were constructed for death on the waiting list and transplantation and used to evaluate outcomes.In 517 listings, the mean death rate per 100 patient-years was 10.4. A total of 375 (72.5% of all listings) were transplanted. Of all transplantations, 352 (93.9%) were ABO-identical and 23 (6.1%) ABO-compatible. The 5-year cumulative incidence of death was 11.2% (SE 1.4%), and of transplantation 72.5% (SE 2.0%). Patient blood group had no multivariate significant impact on the hazard of dying on the waiting list nor on transplantation. Age, MELD score, and urgency status were significantly related to the death on the waiting list and transplantation. More recent listing had higher probability of being transplanted. In the MELD era, patient blood group status does not have a significant impact on liver transplant waiting list mortality nor on waiting time for transplantation.

Abstract
This study assesses the relation between the anhepatic phase duration and the outcome after liver transplantation. Of 645 patients who underwent transplantation between 1994 and 2006, 194 were recipients of consecutive adult primary piggyback liver transplants using heart-beating donors. The anhepatic phase was defined as the time from the physical removal of the liver from the recipient to recirculation of the graft. Other noted study variables were the cold and warm ischemia times, donor and recipient age, donor and recipient body mass index, perioperative red blood cell (RBC) transfusion, indication for transplantation, and Model for End-Stage Liver Disease score. The primary outcome parameter was graft dysfunction, which was defined as either primary nonfunction or initial poor function according to the Ploeg-Maring criteria. The median anhepatic phase was 71 minutes (37-321 minutes). Graft dysfunction occurred in 27 patients (14%). Logistic regression analysis showed an anhepatic phase over 100 minutes [odds ratio (OR), 4.28], a recipient body mass index over 25 kg/m(2) (OR, 3.21), and perioperative RBC transfusion (OR, 3.04) to be independently significant predictive factors for graft dysfunction. One-year patient survival in patients with graft dysfunction was 67% versus 92% in patients without graft dysfunction (P < 0.001). A direct relation between the anhepatic phase duration and patient survival could, however, not be established. In conclusion, this study shows that liver transplant patients with an anhepatic phase over 100 minutes have a higher incidence of graft dysfunction. Patients with graft dysfunction have significantly worse 1-year patient survival.

Is Roux-en-Y choledochojejunostomy an independent risk factor for nonanastomotic biliary strictures after liver transplantation? Liver Transpl 2009; 15:924-30.

Abstract
Biliary reconstruction using Roux-en-Y choledochojejunostomy has been suggested as a risk factor for the development of nonanastomotic biliary strictures (NAS) after liver transplantation. Roux-en-Y reconstruction, however, is preferentially used in patients transplanted for primary sclerosing cholangitis (PSC), and the disease itself is also associated with a higher incidence of NAS. The aim of this study was to determine whether Roux-en-Y reconstruction is really an independent risk factor for NAS. A series of 486 consecutive adult liver transplants were studied. Biliary reconstruction in patients transplanted for PSC was either by Roux-en-Y choledochojejunostomy or by duct-to-duct anastomosis, depending on the quality of the recipient's extrahepatic bile duct. Univariate and multivariate statistical analyses were used to identify risk factors for the development of NAS. The overall incidence of NAS was 16.5% (80/486). In univariate analyses, the following variables were significantly associated with NAS: PSC as the indication for transplantation, type of biliary reconstruction (Roux-en-Y versus duct-to-duct), and postoperative cytomegalovirus infection. After multivariate logistic regression analysis, PSC as the indication for transplantation (odds ratio, 2.813; 95% confidence interval, 1.624-4.875; P < 0.001) and postoperative cytomegalovirus infection (odds ratio, 2.098; 95% confidence interval, 1.266-3.477; P = 0.004) remained as independent risk factors for NAS. Biliary reconstruction using Roux-en-Y choledochojejunostomy was not identified as an independent risk factor for NAS. In conclusion, the association between Roux-en-Y choledochojejunostomy and NAS observed in previous studies can be explained by the more frequent use of Roux-en-Y reconstruction in patients with PSC. Roux-en-Y reconstruction itself is not an independent risk factor for NAS. Liver Transpl 15:924-930, 2009. (c) 2009 AASLD.

Abstract
OBJECTIVE The objective of this study is to assess the outcome of liver resections in the elderly in a matched control analysis. PATIENTS AND METHODS From a prospective single center database of 628 patients, 132 patients were aged 60 years or over and underwent a primary major liver resection. Of these patients, 93 could be matched one-to-one with a control patient, aged less than 60 years, with the same diagnosis and the same type of liver resection. The mean age difference was 16.7 years. RESULTS Patients over 60 years of age had a significantly higher American Society of Anaesthesiologists (ASA) grade. All other demographics and operative characteristics were not different. In-hospital mortality and morbidity were higher in the patients over 60 years of age (11% versus 2%, p = 0.017 and 47% versus 31%, p = 0.024). One-, 3-, and 5-year survival rates in the patients over 60 years of age were 81%, 58%, and 42%, respectively, compared to 90%, 59%, and 42% in the control patients (p = 0.558). Unified model Cox regression analysis showed that resection margin status (hazard ratio 2.51) and ASA grade (hazard ratio 2.26), and not age, were determining factors for survival. CONCLUSION This finding underlines the important fact that in patient selection for major liver resections, ASA grade is more important than patient age.

Abstract
Large cost variations of liver transplantation are reported. The aim of this study was to assess cost differences of liver transplantation and clinical follow-up between the United States and other Organization for Economic Cooperation and Development (OECD) countries. Eight electronic databases were searched, and 2,000 citations published after 1990 with more than 10 transplantations, and with original cost data, were identified. A total of 30 articles included 5,975 liver transplantations. Meta-analysis was used to derive a combined mean using a random-effects model to test for heterogeneity between studies. Estimated mean cost of a U.S. liver transplantation was US$163,438 (US$145,277-181,598) compared to US$103,548 (US$85,514-121,582) for other OECD countries. Patient characteristics, disease characteristics, quality of the health care provider, and methodology could not explain this cost difference. Health system characteristics differed between the U.S. and other OECD countries. Cost differences in liver transplantation between these two groups may be largely explained by health system characteristics.

Abstract
Nonanastomotic biliary strictures (NAS) are a serious complication after orthotopic liver transplantation (OLT). The exact pathogenesis is unclear. Purpose of this study was to identify risk factors for the development of NAS after OLT. A total of 487 adult liver transplants with a median follow-up of 7.9 years were studied. All imaging studies of the biliary tree were reviewed. Cholangiography was routinely performed between postoperative days 10-14 and later on demand. Localization of NAS at first presentation was categorized into 4 anatomical zones of the biliary tree. Severity of NAS was semiquantified as mild, moderate, or severe. Donor, recipient, and surgical characteristics and variables were analyzed to identify risk factors for NAS. NAS developed in 81 livers (16.6%). Thirty-seven (7.3%) were graded as moderate to severe. In 85% of the cases, anatomical localization of NAS was around or below the bifurcation of the common bile duct. A large variation was observed in the time interval between OLT and first presentation of NAS (median 4.1 months; range 0.3-155 months). NAS presenting early (< or =1 year) after OLT were associated with preservation-related risk factors. Cold and warm ischemia times were significantly longer in patients with early NAS compared with NAS presenting late (>1 year) after OLT (694 minutes vs. 490 minutes, P = 0.01, and 57 minutes vs. 53 minutes, P < 0.05, respectively), and early NAS were more frequently located in the central bile ducts. NAS presenting late (>1 year) after OLT were found more frequently in the periphery of the liver and were more frequently associated with immunological factors, such as primary sclerosing cholangitis, as the indication for OLT (24% vs. 45%, P < 0.05). By separating cases of NAS on the basis of the time of presentation after transplantation, we were able to identify differences in risk factors, indicating different pathogenic mechanisms depending on the time of initial presentation.

Abstract
OBJECTIVE To study the safe and unsafe duration of fasting in children with medium chain acyl-Coenzyme A dehydrogenase (MCAD) deficiency, the literature and the database on Dutch MCAD-deficient patients were searched for data on fasting studies in patients with MCAD deficiency. MATERIALS AND METHODS These data were extended with information on fasting studies performed on our patients with MCAD deficiency known in the Beatrix Children's Hospital, UMC Groningen, The Netherlands. The data reflect considerable inter-individual variation and overlap between safe and unsafe duration of fasting. RESULTS In six out of 35 fasting tests, symptoms were reported before hypoglycaemia was observed. Until 1 year of age, the median safe and unsafe duration of fasting was 12 hours (n=7, range 8-19 hours) and 18 hours (n=5, range 15-20 hours), respectively. After the first year of life, the median safe and unsafe duration of fasting was 18 hours (n=17, range 10-24 hours) and 20 hours (n=9, range 13-32 hours), respectively. CONCLUSION Therefore, to conclude, we recommend a maximum duration of fasting in children with MCAD deficiency of 8 hours between 6 months and 1 year of age, 10 hours in the second year of life and 12 hours thereafter. From this study, no conclusions can be drawn on the duration of fasting during situations of intercurrent illness, especially with fever.

Abstract
The exact frequency and clinical consequences of surgical hepatic injuries during organ procurement are unknown. We analyzed the incidence, risk factors, and clinical outcome of surgical injuries in 241 adult liver grafts. Hepatic injuries were categorized as parenchymal, vascular, or biliary. Outcome variables were bleeding complications, hepatic artery thrombosis (HAT), and graft survival. In 82 livers (34%), 96 injuries were detected. Most injuries were minor, but clinically relevant injuries were detected in 6.6% (16/241) of the livers. Fifty (21%) liver grafts had some degree of parenchymal or capsular injury, 40 (17%) had vascular injury, and 6 (2%) had an injury to the bile duct. Procurement region was the only risk factor significantly associated with surgical injury. The rate of hepatic artery injury was significantly higher in livers with aberrant arterial anatomy. Bleeding complications were found in 18% of patients who received livers with a parenchymal or capsular injury in contrast to 9% without parenchymal injury (P = 0.065). HAT was found in 23% of the patients who received a liver with arterial injury compared to 4% without arterial injury (P = 0.001). Overall graft survival rates were not significantly different for grafts with or without anatomical injury. In conclusion, surgical injuries of donor livers are an underestimated problem in liver transplantation and can be observed in about one-third of all cases. Clinically relevant injuries are detected in 6.6% of all liver grafts. Arterial injuries are associated with an increased risk of HAT.

Abstract
Objectives:In cost-minimization studies, it is important to establish noninferiority in the clinical effect of the treatments under investigation. The relationship between the proportion of patients reaching the end point in a study, equivalence limit (δ), and power is investigated in the context of cost-minimization studies with dichotomous clinical end points. Two formulations of the null-hypothesis, absolute and relative formulations of δ, will be explored.Methods:Sensitivity analysis was performed, in which the effect of the predicted proportions and δ on the power in a noninferiority setting was investigated. The patterns found are discussed in terms of the practical relevance within the cost-minimization framework.Results:Sensitivity analyses show different patterns of results for both null-hypotheses. The differences in these results originate from the way δ is expressed. By expressing δ as absolute difference, power grows quite fast when sample proportions are smaller than expected. In the case of a proportional δ at small sample proportions, the power to establish noninferiority remains low.Conclusions:To obtain valid results from a cost-minimization study, care has to be taken to adapt the correct methodology for noninferiority testing in clinical outcomes. Defining δ in terms of absolute differences between treatments can lead to obscured results. Although conservative, the expression of δ as a proportion of the effectiveness of the treatment as usual is found to be closer to clinical practice. The inflated δ, resulting from smaller clinical effects than expected when absolute formulation is applied, thus can be avoided.
