Abstract
OBJECTIVE Tofacitinib is an oral Janus kinase inhibitor approved for the treatment of ulcerative colitis (UC). The objective of this study was to evaluate the long-term cost-effectiveness of tofacitinib versus current biologics, considering combinations of first-line (1L) and second-line (2L) therapies, from a Japanese payer's perspective in patients with moderate-to-severe active UC following an inadequate response to conventional therapy and in those who were naïve to biologics. METHODS A cost-effectiveness analysis was conducted during the time horizon specified in the Markov model, which considers a patient's lifetime as 60 years and an annual discount rate of 2% on costs and effects. The model compared tofacitinib with vedolizumab, infliximab, adalimumab, golimumab, and ustekinumab. The time of active treatment was divided into induction and maintenance phases. Patients not responding to their biologic treatment after induction or during the maintenance phase were switched to a subsequent line of therapy. Treatment response and remission probabilities (for induction and maintenance phases) were obtained through a systematic literature review and a network meta-analysis that employed a multinomial analysis with fixed effects. Patient characteristics were sourced from the OCTAVE Induction trials. Mean utilities associated with UC health states and adverse events (AEs) were obtained from published sources. Direct medical costs related to drug acquisition, administration, surgery, patient management, and AEs were derived from the JMDC database analysis, which corresponded with the medical procedure fees from 2021. The drug prices were adjusted to April 2021. Further validation through all processes by clinical experts in Japan was conducted to fit the costs to real-world practices. Scenario and sensitivity analyses were also performed to confirm the accuracy and robustness of the base-case results. RESULTS In the base-case, the treatment pattern including 1L tofacitinib was more cost-effective than vedolizumab, infliximab, golimumab, and ustekinumab for 1L therapies in terms of cost per quality-adjusted life year (QALY) gained (based on the Japanese threshold of 5,000,000 yen/QALY [38,023 United States dollars {USD}/QALY]). The base-case results demonstrated that the incremental costs would be reduced for all biologics, and decreases in incremental QALYs were observed for all biologics other than adalimumab. The incremental cost-effectiveness ratio (ICER) was found to be dominant for adalimumab; for the other biologics, it was found to be less costly and less efficacious. The efficiency frontier on the cost-effectiveness plane indicated that tofacitinib-infliximab and infliximab-tofacitinib were more cost-effective than the other treatment patterns. When infliximab-tofacitinib was compared with tofacitinib-infliximab, the ICER was 282,609,856 yen/QALY (2,149,157 USD/QALY) and the net monetary benefit (NMB) was -12,741,342 yen (-96,894 USD) with a threshold of 5,000,000 yen (38,023 USD) in Japan. Therefore, infliximab-tofacitinib was not acceptable by this threshold, and tofacitinib-infliximab was the cost-effective treatment pattern. CONCLUSION The current analysis suggests that the treatment pattern including 1L tofacitinib is a cost-effective alternative to the biologics for patients with moderate-to-severe UC from a Japanese payer's perspective.

MDM Policy Pract 2023; 8:23814683231156433. [PMID: 36860664 PMCID: PMC9969457 DOI: 10.1177/23814683231156433] [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: 02/10/2022] [Accepted: 01/17/2023] [Indexed: 03/03/2023] Open
Abstract
Background. Policies mandating the use of lower cost biosimilars in patients with inflammatory bowel disease (IBD) have created concerns for patients who prefer their original biologic. Purpose. To inform the cost-effectiveness of biosimilar infliximab treatment in IBD by systematically reviewing the effect of infliximab price variation on cost-effectiveness for jurisdictional decision making. Data Sources. MEDLINE, Embase, Healthstar, Allied and Complementary Medicine, Joanna Briggs Institute EBP Database, International Pharmaceutical Abstracts, Health and Psychosocial Instruments, Mental Measurements Yearbook citation databases, PEDE, CEA registry, HTA agencies. Study Selection. Economic evaluations of infliximab for adult or pediatric Crohn's disease and/or ulcerative colitis published from 1998 through 2019 in which drug price was varied in sensitivity analysis were included. Data Extraction. Study characteristics, main findings, and results of drug price sensitivity analyses were extracted. Studies were critically appraised. The cost-effective price of infliximab was determined based on the stated willingness-to-pay (WTP) thresholds for each jurisdiction. Data Synthesis. Infliximab price was examined in sensitivity analysis in 31 studies. Infliximab showed favorable cost-effectiveness at a price ranging from CAD $66 to $1,260 per vial, depending on jurisdiction. A total of 18 studies (58%) demonstrated cost-effectiveness ratios above the jurisdictional WTP threshold. Limitations. Drug prices were not always reported separately, WTP thresholds varied, and funding sources were not consistently reported. Conclusion. Despite the high cost of infliximab, few economic evaluations examined price variation, limiting the ability to infer the effects of biosimilar introduction. Alternative pricing strategies and access to treatment could be considered to enable IBD patients to maintain access to their current medications. Highlights In an effort to reduce public drug expenditures, Canadian and other jurisdictional drug plans have mandated the use of lower cost, but similarly effective, biosimilars in patients with newly diagnosed inflammatory bowel disease or require a nonmedical switch for established patients. This switch has created concerns for patients and clinicians who want to maintain the ability to make treatment decisions and remain with the original biologic.It is customary for economic evaluations to assess the robustness of results to variations in high-cost items such as medications. In the absence of economic evaluations of biosimilars, examining biologic drug price in sensitivity analysis provides insight into the cost-effectiveness of biosimilar alternatives. A total of 31 economic evaluations of infliximab for the treatment of inflammatory bowel disease varied the infliximab price in sensitivity analysis.The infliximab price deemed to be cost-effective within each study ranged from CAD $66 to CAD $1,260 per 100-mg vial. A total of 18 studies (58%) demonstrated an incremental cost-effectiveness ratio above the jurisdictional willingness-to-pay threshold. If policy decisions are based on price, then originator manufacturers could consider reducing the price or negotiating alternative pricing models to enable patients with inflammatory bowel disease to remain on their current medications.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of tofacitinib versus other treatment options currently available for the management of adult patients with moderate-to-severe ulcerative colitis, who have had an inadequate response, loss of response, or were intolerant to conventional therapy or a biologic agent, in Greece. METHODS A Markov model was adapted for projecting lifetime costs and outcomes, for a cohort of patients with moderate-to-severe ulcerative colitis from a Greek payer perspective. Patients entered the model in the active ulcerative colitis state and transitioned to a remission or response state or they underwent colectomy. Following an initial 8-week induction treatment period, patients received maintenance therapy until loss of response. Nonresponders could switch to up to two subsequent biologic lines. Clinical efficacy, adverse event rates and utilities derived from OCTAVE trials and a network-meta-analysis (NMA), while adverse event-related disutilities were obtained from the literature. Information on treatment pathways and resource use was provided by an advisory board due to a lack of local data. Unit costs derived from official national sources (€, 2018). RESULTS Over a life-time horizon, treating moderate-to-severe active ulcerative colitis with tofacitinib resulted in additional quality-adjusted life-years (QALYs) and lower total costs compared to vedolizumab (0.018; €6408), infliximab (biosimilar) (0.009; €3031), golimumab (0.042; €1988) and infliximab (originator) (0.009; €6724). Hence, tofacitinib was estimated to be dominant over all comparators. CONCLUSION The results of the analysis suggest that in the Greek setting, tofacitinib could be considered a cost-effective (dominant) treatment option for the treatment of patients with moderate-to-severe active ulcerative colitis.

Abstract
BACKGROUND AND AIMS Infliximab rescue therapy is effective in patients with corticosteroid refractory acute severe ulcerative colitis, but predictors of response remain poorly understood. We aimed to identify predictors of colectomy in this high-risk patient population. METHODS Patients hospitalized with acute severe ulcerative colitis who received infliximab after failing intravenous corticosteroid therapy between July 2012 and June 2017 were retrospectively identified. Stepwise regression with backward elimination was used to identify predictors of colectomy at 90 days and 1 year. Ninety-day and 1-year colectomy rates were compared between the patients who received 5 mg/kg and 10 mg/kg IFX rescue dose. RESULTS Sixty-three patients met the eligibility criteria. Twenty-nine patients received 5 mg/kg, and 34 received 10 mg/kg infliximab dose. Serum albumin on admission (OR 0.10; p = 0.04) and band neutrophil percentage at the time of infliximab administration (OR 1.21; p = 0.02) were independent predictors of 90-day colectomy. A combination of serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy. Unadjusted 90-day and 1-year colectomy rates were similar in the 5 mg/kg and 10 mg/kg infliximab groups. After adjusting for confounding factors, 10 mg/kg infliximab dose was potentially protective for 90-day (OR 0.07; p = 0.06) but not for 1-year colectomy (OR 0.19; p = 0.16). CONCLUSIONS Bandemia and low serum albumin are independent predictors of failure of infliximab rescue therapy in acute severe ulcerative colitis. Serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy.

Abstract
BACKGROUND AND AIM Inflammatory bowel disease (IBD) patients are at risk for recurrent Clostridium difficile infection (RCDI). We aimed to evaluate the potential health economic and clinical outcomes of four strategies for management of RCDI in IBD patients from the perspective of public health-care provider in Hong Kong. METHODS A decision-analytic model was designed to simulate outcomes of adult IBD patients with first RCDI treated with vancomycin, vancomycin plus bezlotoxumab, fidaxomicin and fecal microbiota transplantation (FMT). Model inputs were derived from literature and public data. Primary model outcomes were C. difficile infection (CDI)-related direct medical cost and quality-adjusted life-years (QALYs) loss. Base-case and sensitivity analysis were performed. RESULTS Comparing to vancomycin, fidaxomicin and vancomycin plus bezlotoxumab, FMT saved 0.00318, 0.00149 and 0.00306 QALYs and reduced cost by USD3180, USD3790 and USD5514, respectively, in base-case analysis. In probabilistic sensitivity analysis, FMT was cost-saving when comparing to vancomycin, fidaxomicin and vancomycin plus bezlotoxumab by USD3765 (95% confidence interval [CI] 3732-3798; P < 0.001), USD3854 (95%CI 3827-3883; P < 0.001) and USD6501 (95%CI 6465-6,536; P < 0.001), respectively. The QALYs saved by FMT (vs vancomycin) were 0.00386 QALYs (95%CI 0.00384-0.00388; P < 0.001), (vs fidaxomicin) 0.00179 QALYs (95%CI 0.00177-0.00180; P < 0.001) and (vs vancomycin plus bezlotoxumab) 0.00376 QALYs (95%CI 0.00374-0.00378; P < 0.001). FMT was found to save QALYs at lower cost in 99.3% (vs vancomycin), 99.7% (vs fidaxomicin) and 100.0% (vs vancomycin plus bezlotoxumab) of the 10 000 Monte Carlo simulations. CONCLUSIONS FMT for IBD patients with RCDI appeared to save both direct medical cost and QALYs when comparing to vancomycin (with or without bezlotoxumab) and fidaxomicin.

Abstract
BACKGROUND Ileal pouch-anal anastomosis (IPAA) is the mainstay of surgical treatment for patients with ulcerative colitis (UC) but is associated with an increased risk of infertility. We developed a simulation model examining the impact of initial surgical procedure on quality-adjusted life-years (QALYs) and fertility end points. METHODS A patient-level state transition model was used to analyze outcomes by surgical approach strategy for females of childbearing age. Initial surgical options included IPAA, rectal-sparing colectomy with end ileostomy (RCEI), and ileorectal anastomosis (IRA). The primary outcome examined was QALYs, whereas secondary outcomes included UC and fertility-associated end points. RESULTS IPAA resulted in higher QALYs for patients aged 20-30 years, as compared with RCEI. For patients aged 35 years, RCEI resulted in higher QALYs (7.54 RCEI vs 7.53 IPAA) and was associated with a 28% higher rate of childbirth, a 14-month decrease in time to childbirth, and a 77% reduction in in vitro fertilization utilization. When accounting for the decreased infertility risk associated with laparoscopic IPAA, IPAA resulted in higher QALYs (7.57) even for patients aged 35 years. CONCLUSIONS Despite an increased risk of infertility, our model results suggest that IPAA may be the optimal surgical strategy for female UC patients aged 20-30 years who desire children. For patients aged 35 years, RCEI should additionally be considered, as QALYs for RCEI and IPAA were similar. These quantitative data can be used by patients and providers to help develop an individualized approach to surgical management choice.

Abstract
Correlation between fecal calprotectin (FC) and endoscopic activity assessed by Ulcerative Colitis Endoscopic Index of Severity (UCEIS) in acute severe colitis (ASC) patients was explored to evaluate the predictive value of FC in clinical outcomes. Seventy-one ASC patients were retrospectively evaluated. FC level within 3 days of colonoscopy was measured with ELISA. Demographic and clinical data, laboratory parameters, and medical therapy were documented, and the endoscopic severity of disease was rated by UCEIS. The end points were the rate of failed corticosteroid therapy, colectomy, and mortality. There was significant correlation between UCEIS and FC level (r=0.729, P<0.001), which was superior to CRP, ESR, and hemoglobin. FC level between endoscopic mild activity (UCEIS, 3-4) and endoscopic moderate activity (UCEIS, 5-6), and endoscopic moderate activity (UCEIS, 5-6) and endoscopic severe activity (UCEIS, 7-8) were significantly different. FC levels were associated with different outcomes (failed corticosteroid therapy or surgery); when FC >1672 µg/g, sensitivity and specificity were 80.2 and 66.7%, respectively, in prediction for colectomy using receiver operating characteristics analysis. The results indicated that FC, as a non-invasive indicator, correlates positively with the UCEIS. Baseline FC level predicts clinical outcomes in ASC patients, which make a timely treatment strategy conversion possible after accurately forecasting the likelihood of failure of intravenous steroid therapy.

Abstract
Background Early intervention for acute severe ulcerative colitis (ASUC) improves outcomes. Outcomes and healthcare costs for an infliximab-first and colectomy-first approach were compared. Methods This single-center retrospective cohort study of inpatients with steroid-refractory ASUC who received infliximab 5 mg/kg (1-3 doses without maintenance) or initial colectomy between 2004 and 2014 assessed long-term healthcare utilization and direct costs following infliximab or colectomy, using admission coding data until 31 December 2016. Results A total of 118 patients received either infliximab (n = 85, 72%) or colectomy (n = 33, 28%) as initial therapy, with 35(41%) patients eventually requiring colectomy post-infliximab (median 213 days, range [6, 3739]). Median follow up was 7 years [0, 14]. Following infliximab for ASUC, 44% of patients then received antitumor necrosis factor maintenance. After ASUC therapy, length of stay and number of admissions did not significantly differ between groups but higher numbers of complications prompting readmission occurred in the colectomy group (median 4 versus 1, p < 0.001). There were no differences in admissions or total length of stay for patients who had received infliximab first then colectomy versus those treated with colectomy first (median 7.0 versus 4.0, 41.5 days versus 29 days, respectively, each p > 0.05). Total costs were lower at 6 months (mean AUD17,662 versus AUD24,852, p = 0.003), yet were similar at 7 years following an infliximab compared with colectomy approach (AUD72,834 versus AUD59,557, p = 0.23). After infliximab, costs were significantly higher at 7 years with biologic rather than immunomodulator-only maintenance therapy (AUD109,365 versus AUD47,842, p < 0.01). Conclusions In support of current practice, infliximab salvage in steroid-refractory ASUC achieved reduced short-term healthcare costs compared with initial colectomy, though long-term costs were not significantly different.

Abstract
BACKGROUND There is no general consensus regarding the ideal timing of surgery in patients with refractory ulcerative colitis (UC). Decision-making and timing of restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is influenced by treating physicians and patients themselves. The aim of this study was to determine whether or not patients would have preferred the operation to be performed earlier, at the same time, or at a later point of time and to determine the reasons for their preference. METHODS Clinical data of 193 patients with UC who have undergone IPAA were documented in a prospective database at our institution between 2004 and 2015. From this database, 190 patients were identified and a standardized custom-made questionnaire was mailed for follow-up survey. Patients who did not respond were called by telephone and encouraged to complete the questionnaire. RESULTS One hundred nine questionnaires were eligible for analysis (57.4%). Average time between diagnosis and surgery was 11.2 ± 10.8 years (mean ± SD). Indications for surgery were refractory disease (70.6%), colitis-associated colorectal cancer (11.0%), high-grade dysplasia or stenosis (11.9%), and septic complications of UC (6.4%); 39 of 77 patients (50.6%) with refractory UC reported to have preferred their operation to be carried out earlier as it was actually performed (16.8 ± 11.9 months). Refractory course of the disease was identified as a predictor for a retrospectively desired earlier surgical approach (p = 0.014). CONCLUSION A substantial proportion of patients felt that they should have undergone surgery earlier than actually performed. It appears that timing of the decision to undergo surgery is suboptimal. This situation may be improved by earlier surgical consultation in the course of the disease.

Risk of post-operative surgical site infections after vedolizumab vs anti-tumour necrosis factor therapy: a propensity score matching analysis in inflammatory bowel disease. Aliment Pharmacol Ther 2018; 48:340-346. [PMID: 29876995 PMCID: PMC6043399 DOI: 10.1111/apt.14842] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2018] [Revised: 04/27/2018] [Accepted: 05/20/2018] [Indexed: 12/21/2022]
Abstract
BACKGROUND Perioperative vedolizumab (VDZ) and anti-tumour necrosis factor (TNFi) therapies are implicated in causing post-operative complications in inflammatory bowel disease (IBD). AIM To compare the risk of surgical site infections (SSIs) between VDZ- and TNFi-treated IBD patients in propensity-matched cohorts. METHODS The Optum Research Database was used to identify IBD patients who received VDZ or TNFi within 30 days prior to abdominal surgery between January 2015 and December 2016. The date of IBD-related abdominal surgery was defined as the index date. SSIs were determined by ICD-9/10 and CPT codes related to superficial wound infections or deep organ space infections after surgery. Propensity score 1:1 matching established comparable cohorts based on VDZ or TNFi exposure before surgery based on evidence-based risk modifiers. RESULTS The propensity-matched sample included 186 patients who received pre-operative biologic therapy (VDZ, n = 94; TNFi, n = 92). VDZ and TNFi cohorts were similar based on age, gender, IBD type, concomitant immunomodulator exposure, chronic opioid or corticosteroid therapy, Charlson Comorbidity Index and malnutrition. VDZ patients were more likely to undergo an open bowel resection with ostomy. After propensity score matching, there was no significant difference in post-operative SSIs (TNFi 12.0% vs VDZ 14.9%, P = 0.56). Multivariable analysis indicated that malnutrition was the sole risk factor for developing SSI (OR 3.1, 95% CI 1.11-8.71) regardless of the type of biologic exposure. CONCLUSION In the largest, risk-adjusted cohort analysis to date, perioperative exposure to VDZ therapy was not associated with a significantly higher risk of developing an SSI compared to TNFi therapy.

Abstract
OBJECTIVE The objective of this literature review was to evaluate the existing evidence regarding the cost-effectiveness of treatment options in IBD. METHODS A systematic review of the literature was conducted to identify economic evaluations of IBD therapy. The literature search was performed using electronic databases MEDLINE and EMBASE. Searches were limited to full economic evaluations published in English or French between 2004 and 2016. RESULTS A total of 5,403 potentially relevant studies were identified. After screening titles and abstracts, 48 studies were included, according to the eligibility criteria. A total of 56% and 42% of the studies were assessing treatments of UC or CD, respectively. Treatment options under evaluation included biological agents, mesalamine, immunosuppressants, and surgery. The majority of studies evaluated the cost-effectiveness of biological treatments. Biological therapies were dominant in 23% of the analyses and were cost-effective according to a $CAD50,000/QALY and $CAD100,000/QALY threshold in 41% and 62% of the analyses, respectively. CONCLUSION This literature review provided a comprehensive overview of the economic evaluations for the different treatment options for IBD over the past 12 years and represents a helpful reference for future economic evaluations.

Abstract
BACKGROUND Ulcerative colitis (UC) is the most common form of inflammatory bowel disease in the UK. UC can have a considerable impact on patients' quality of life. The burden for the NHS is substantial. OBJECTIVES To evaluate the clinical effectiveness and safety of interventions, to evaluate the incremental cost-effectiveness of all interventions and comparators (including medical and surgical options), to estimate the expected net budget impact of each intervention, and to identify key research priorities. DATA SOURCES Peer-reviewed publications, European Public Assessment Reports and manufacturers' submissions. The following databases were searched from inception to December 2013 for clinical effectiveness searches and from inception to January 2014 for cost-effectiveness searches for published and unpublished research evidence: MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library including the Cochrane Systematic Reviews Database, Cochrane Controlled Trials Register, Database of Abstracts of Reviews of Effects, the Health Technology Assessment database and NHS Economic Evaluation Database; ISI Web of Science, including Science Citation Index, and the Conference Proceedings Citation Index-Science and Bioscience Information Service Previews. The US Food and Drug Administration website and the European Medicines Agency website were also searched, as were research registers, conference proceedings and key journals. REVIEW METHODS A systematic review [including network meta-analysis (NMA)] was conducted to evaluate the clinical effectiveness and safety of named interventions. The health economic analysis included a review of published economic evaluations and the development of a de novo model. RESULTS Ten randomised controlled trials were included in the systematic review. The trials suggest that adult patients receiving infliximab (IFX) [Remicade(®), Merck Sharp & Dohme Ltd (MSD)], adalimumab (ADA) (Humira(®), AbbVie) or golimumab (GOL) (Simponi(®), MSD) were more likely to achieve clinical response and remission than those receiving placebo (PBO). Hospitalisation data were limited, but suggested more favourable outcomes for ADA- and IFX-treated patients. Data on the use of surgical intervention were sparse, with a potential benefit for intervention-treated patients. Data were available from one trial to support the use of IFX in paediatric patients. Safety issues identified included serious infections, malignancies and administration site reactions. Based on the NMA, in the induction phase, all biological treatments were associated with statistically significant beneficial effects relative to PBO, with the greatest effect associated with IFX. For patients in response following induction, all treatments except ADA and GOL 100 mg at 32-52 weeks were associated with beneficial effects when compared with PBO, although these were not significant. The greatest effects at 8-32 and 32-52 weeks were associated with 100 mg of GOL and 5 mg/kg of IFX, respectively. For patients in remission following induction, all treatments except ADA at 8-32 weeks and GOL 50 mg at 32-52 weeks were associated with beneficial effects when compared with PBO, although only the effect of ADA at 32-52 weeks was significant. The greatest effects were associated with GOL (at 8-32 weeks) and ADA (at 32-52 weeks). The economic analysis suggests that colectomy is expected to dominate drug therapies, but for some patients, colectomy may not be considered acceptable. In circumstances in which only drug options are considered, IFX and GOL are expected to be ruled out because of dominance, while the incremental cost-effectiveness ratio for ADA versus conventional treatment is approximately £50,300 per QALY gained. LIMITATIONS The health economic model is subject to several limitations: uncertainty associated with extrapolating trial data over a lifetime horizon, the model does not consider explicit sequential pathways of non-biological treatments, and evidence relating to complications of colectomy was identified through consideration of approaches used within previous models rather than a full systematic review. CONCLUSIONS Adult patients receiving IFX, ADA or GOL were more likely to achieve clinical response and remission than those receiving PBO. Further data are required to conclusively demonstrate the effect of interventions on hospitalisation and surgical outcomes. The economic analysis indicates that colectomy is expected to dominate medical treatments for moderate to severe UC. STUDY REGISTRATION This study is registered as PROSPERO CRD42013006883.

Abstract
PURPOSE Up to a third of patients with acute severe ulcerative colitis (ASUC) fail to respond to intensive steroid therapy and eventually require a salvage colectomy. We have previously reported that the mortality of emergency colectomy can be decreased by offering it within the first week of intensive medical therapy. We implemented this policy and report the results of our experience. METHODS The clinical records of all patients with ASUC who underwent emergency colectomy after failure of medical therapy between January 2005 and July 2015 were extracted from a prospectively maintained database. The data were analysed with regard to duration of intensive medical therapy, timing of surgery, in-hospital mortality and post-operative complications. RESULTS Eighty-eight patients underwent emergency surgery for ASUC after failed medical therapy. Of these, 75 (85.2%) were operated within 7 days of initiation of intensive medical therapy [n = 51 (58%) were operated < 5 days]. One patient who was operated on day 8 following steroid therapy died postoperatively. The current post-operative mortality of 1.1% (1/88) was significantly lower than the mortality noted in the previously recorded retrospective case series [8/51 (15.6%); p = 0.001]. In addition, the incidence of overall (9/13 vs. 23/75; p = 0.012) and clinically significant (12/75 vs. 6/13; p = 0.022) complications was significantly higher in patients operated after 7 days as compared to those operated within 7 days. CONCLUSION The policy of early colectomy, within 7 days, in patients with ASUC who fail to respond to intensive steroid-based therapy improves perioperative outcomes with significantly low in-hospital mortality and morbidity.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic disease placing a large health and economic burden on health systems worldwide. The treatment landscape is complex with multiple strategies to induce and maintain remission while avoiding long-term complications. The extent to which rising treatment costs, due to expensive biologic agents, are offset by improved outcomes and fewer hospitalisations and surgeries needs to be evaluated. This systematic review aimed to assess the cost-effectiveness of treatment strategies for IBD. MATERIALS AND METHODS A systematic literature search was performed in March 2017 to identify economic evaluations of pharmacological and surgical interventions, for adults diagnosed with Crohn's disease (CD) or ulcerative colitis (UC). Costs and incremental cost-effectiveness ratios (ICERs) were adjusted to reflect 2015 purchasing power parity (PPP). Risk of bias assessments and a narrative synthesis of individual study findings are presented. RESULTS Forty-nine articles were included; 24 on CD and 25 on UC. Infliximab and adalimumab induction and maintenance treatments were cost-effective compared to standard care in patients with moderate or severe CD; however, in patients with conventional-drug refractory CD, fistulising CD and for maintenance of surgically-induced remission ICERs were above acceptable cost-effectiveness thresholds. In mild UC, induction of remission using high dose mesalazine was dominant compared to standard dose. In UC refractory to conventional treatments, infliximab and adalimumab induction and maintenance treatment were not cost-effective compared to standard care; however, ICERs for treatment with vedolizumab and surgery were favourable. CONCLUSIONS We found that, in general, while biologic agents helped improve outcomes, they incurred high costs and therefore were not cost-effective, particularly for use as maintenance therapy. The cost-effectiveness of biologic agents may improve as market prices fall and with the introduction of biosimilars. Future research should identify optimal treatment strategies reflecting routine clinical practice, incorporate indirect costs and evaluate lifetime costs and benefits.

Abstract
BACKGROUND Ulcerative colitis (UC) is associated with significant health care utilization and costs. We assessed UC direct medical costs in Quebec, Canada, in 2 time periods (1998-2004 and 2005-2011) and determined changes over time. METHODS Because the introduction of anti-tumor necrosis factor α may have influenced the UC cost, we used the Quebec health services administrative databases and the same inclusion criteria to create 2 separate UC cohorts, before (1998-2004) and after (2005-2011) anti-tumor necrosis factor α introduction. RESULTS The postcohort included 801 patients and the precohort 716 patients. Overall, cohorts were predominately women and were comparable in terms of patient's demographics and comorbidities. Corticosteroid use, emergency department visits and hospitalizations for colectomies, and other gastrointestinal disorders were fewer in the postcohort versus precohort. The median daily cost (interquartile range) was $16.96 ($6.80-$48.16) for the postcohort and $18.65 ($7.82-$53.31) for the precohort. In generalized linear models with log link and gamma distribution, the adjusted daily cost ratios (95% confidence interval) in the postcohort versus precohort was 0.75 (0.67-0.85). Older age at inclusion, low income, lower socioeconomic status, and previous use of gastroprotective agents, antidepressants, and sulfasalazine, methotrexate, or cyclosporine were associated with increased costs. Women and those who visited a gastroenterologist in the previous year incurred lower costs. CONCLUSIONS The mean UC daily cost decreased from 2005 to 2011 as compared to 1998 to 2004 because of a decrease in rates of colectomy and other gastrointestinal hospitalizations and emergency department visits. Further investigation is required to determine the reasons for these changes.

Abstract
Background Systematic reviews with meta-analyses and meta-regression suggest that timely probiotic use can prevent Clostridium difficile infection (CDI) in hospitalized adults receiving antibiotics, but the cost effectiveness is unknown. We sought to evaluate the cost effectiveness of probiotic use for prevention of CDI versus no probiotic use in the United States. Methods We programmed a decision analytic model using published literature and national databases with a 1-year time horizon. The base case was modeled as a hypothetical cohort of hospitalized adults (mean age 68) receiving antibiotics with and without concurrent probiotic administration. Projected outcomes included quality-adjusted life-years (QALYs), costs (2013 US dollars), incremental cost-effectiveness ratios (ICERs; $/QALY), and cost per infection avoided. One-way, two-way, and probabilistic sensitivity analyses were conducted, and scenarios of different age cohorts were considered. The ICERs less than $100000 per QALY were considered cost effective. Results Probiotic use dominated (more effective and less costly) no probiotic use. Results were sensitive to probiotic efficacy (relative risk <0.73), the baseline risk of CDI (>1.6%), the risk of probiotic-associated bactermia/fungemia (<0.26%), probiotic cost (<$130), and age (>65). In probabilistic sensitivity analysis, at a willingness-to-pay threshold of $100000/QALY, probiotics were the optimal strategy in 69.4% of simulations. Conclusions Our findings suggest that probiotic use may be a cost-effective strategy to prevent CDI in hospitalized adults receiving antibiotics age 65 or older or when the baseline risk of CDI exceeds 1.6%.

Abstract
BACKGROUND & AIMS The body composition of patients with ulcerative colitis (UC) remains unclear. This study evaluated body composition in adult patients with UC and the associations of body composition with disease activity and surgical intervention. METHODS This study included 99 patients with UC, 105 with Crohn's disease (CD) and 60 controls. Skeletal muscle area (SMA), visceral fat area (VFA) and subcutaneous fat area (SFA) of the third lumbar vertebrae were evaluated by abdominal computed tomography. The effects of medical therapy and surgery on body composition in UC patients were determined. RESULTS Sarcopenia was more frequent in UC patients (27.3%) than in controls (8.3%), but less frequent than in CD patients (59.0%). The prevalence of sarcopenia was significantly higher (33.8% vs. 4.5%, p < 0.001), and SMA (144.26 vs. 182.32 cm2, p < 0.001), skeletal muscle index (SMI) (52.22 vs. 65.52 cm2/m2, p < 0.001) significantly lower, in UC patients with high (≥6) than low (<6) Mayo score, but SFA and VFA were similar. The prevalence of sarcopenia and alterations in body composition were reversed, along with UC disease activity, following medical treatment or surgery. SMA and SMI correlated significantly with disease activity in UC patients. Multivariate analysis showed that sarcopenia (odds ratio, 8.49; 95% confidence interval, 1.80-40.10; p = 0.007) was a negative predictor of high Mayo score in UC patients. Sarcopenic patients with UC had high probability of need for colectomy in Kaplan-Meier survival curves. CONCLUSIONS Sarcopenia is associated with high disease activity and poor clinical outcome in UC patients. Medical treatment and colectomy have positive effects on sarcopenia and skeletal muscle depletion.

Abstract
Acute severe ulcerative colitis (UC) is a highly morbid condition that requires both medical and surgical management through the collaboration of gastroenterologists and colorectal surgeons. First line treatment for patients presenting with acute severe UC consists of intravenous steroids, but those who do not respond require escalation of therapy or emergent colectomy. The mortality of emergent colectomy has declined significantly in recent decades, but due to the morbidity of this procedure, second line agents such as cyclosporine and infliximab have been used as salvage therapy in an attempt to avoid emergent surgery. Unfortunately, protracted medical therapy has led to patients presenting for surgery in a poorer state of health leading to poorer post-operative outcomes. In this era of multiple medical modalities available in the treatment of acute severe UC, physicians must consider the advantages and disadvantages of prolonged medical therapy in an attempt to avoid surgery. Colectomy remains a mainstay in the treatment of severe ulcerative colitis not responsive to corticosteroids and rescue therapy, and timely referral for surgery allows for improved post-operative outcomes with lower risk of sepsis and improved patient survival. Options for reconstructive surgery include three-stage ileal pouch-anal anastomosis or a modified two-stage procedure that can be performed either open or laparoscopically. The numerous avenues of medical and surgical therapy have allowed for great advances in the treatment of patients with UC. In this era of options, it is important to maintain a global view, utilize biologic therapy when indicated, and then maintain an appropriate threshold for surgery. The purpose of this review is to summarize the growing number of medical and surgical options available in the treatment of acute, severe UC.

Colectomy with Permanent End Ileostomy Is More Cost-Effective than Ileal Pouch-Anal Anastomosis for Crohn's Colitis. Dig Dis Sci 2016; 61:550-9. [PMID: 26434930 DOI: 10.1007/s10620-015-3886-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2014] [Accepted: 09/13/2015] [Indexed: 12/18/2022]
Abstract
BACKGROUND Much of the economic burden of Crohn's disease (CD) is related to surgery. Twenty percent of patients with CD have isolated colonic disease. While permanent end ileostomy (EI) is generally the procedure of choice for patients with refractory CD colitis, single-center experiences suggest that restorative proctocolectomy (IPAA) is durable in select patients. AIMS We assessed the cost-effectiveness of total colectomy with permanent EI versus IPAA in medically refractory colonic CD. METHODS We used a lifetime Markov model with 6-month cycles to simulate quality-adjusted life years (QALYs) and cost. In each of the EI and IPAA strategies, patients could transition between multiple health states. One-way and multivariable sensitivity analysis and tornado analysis were performed to identify thresholds for factors influencing cost-effectiveness. RESULTS IPAA was more effective than EI surgery with an incremental cost-effectiveness ratio of $70,715 per QALY gained. We identified the following variables of importance in our model: (1) the cost of the EI surgery, (2) the cost of infliximab, and (3) the cost of gastroenterology ambulatory visit and labs. Threshold analysis revealed that if the costs associated with EI surgery exceeded $20,167 or if the utility of IPAA with CD remission without medical therapy exceeded 0.37, IPAA became the more cost-effective strategy. CONCLUSIONS In patients with medically refractory CD isolated to the colon, colectomy with permanent EI is more cost-effective than IPAA unless the costs associated with the EI surgery exceed $20,167 or if the utility associated with IPAA and CD remission exceeds 0.37.

Abstract
BACKGROUND Patients undergoing colectomy for ulcerative colitis (UC) may experience complications associated with reduced quality of life (QoL), and maybe a considerable economic burden to healthcare systems. Appreciation of these burdens is important to evaluate the cost effectiveness of newer interventions for UC vs. colectomy. AIM To identify data representing resource utilisation or costs of complications arising from colorectal procedures in patients with UC, and data representing patient QoL, as reported by health state utility values (HSUVs). METHODS Embase, MEDLINE and The Cochrane Library were searched for studies (1995-2014) reporting resource use/costs of surgical complications, and HSUVs data in adult patients with UC, undergoing colorectal procedures. Conference proceedings (January 2011-January 2014) were hand-searched. RESULTS Twelve studies reported resource use/costs, and three reported HSUVs data in patients with UC experiencing surgical complications. Additional mean costs of postoperative complications ranged from $18 650/patient with complications at a 6-month follow-up (46% incidence) to $34 714/patient with complications over a 5-year period (49% incidence). Pouchitis, pouch failure and small bowel obstruction carried the greatest burden. Marked reductions in HSUVs were observed for patients with UC experiencing surgical complications, vs. patients with UC in a remission state. CONCLUSIONS There is a paucity of well reported studies on resource use/cost, and QoL burden of surgical complications in patients with UC. However, surgical complications represent a substantial burden both in terms of cost and of quality of life, with reoperations, physician fees, additional in-patient hospital stays and infertility treatment being the main cost drivers.

Abstract
OBJECTIVE To determine the short-term costs per sustained remission and sustained response of three tumor necrosis factor inhibitors (infliximab, adalimumab, and golimumab) in comparison to conventional therapy for the treatment of moderately-to-severely active ulcerative colitis. METHODS A probabilistic Markov model was developed. This included an 8-week induction period, and 22 subsequent 2-week cycles (up to 1 year). The model included three disease states: remission, response, and relapse. Costs were from a Canadian public payer perspective. Estimates for the additional cost per 1 year of sustained remission and sustained response were obtained. RESULTS Golimumab 100 mg provided the lowest cost per additional remission ($935) and cost per additional response ($701) compared with conventional therapy. Golimumab 50 mg yielded slightly higher costs than golimumab 100 mg. Infliximab was associated with the largest additional number of estimated remissions and responses, but also higher cost at $1975 per remission and $1311 per response. Adalimumab was associated with the largest cost per remission ($7430) and cost per response ($2361). The cost per additional remission and cost per additional response associated with infliximab vs golimumab 100 mg was $14,659 and $4753, respectively. CONCLUSIONS The results suggest that the additional cost of 1 full year of remission and response are lowest with golimumab 100 mg, followed by golimumab 50 mg. Although infliximab has the highest efficacy, it did not exhibit the lowest cost per additional remission or response. Adalimumab produced the highest cost per additional remission and response.

Abstract
OBJECTIVE To assess the impact of surgical harm on quality of life (QoL) in general and gastrointestinal surgery. BACKGROUND Surgical adverse events (SAEs) are associated with poor outcome. Although SAEs are likely to affect QoL, this has not been demonstrated in surgery. METHODS Studies in general and gastrointestinal surgery measuring postoperative QoL in patients who suffered SAEs were identified. The overall impact of SAEs on QoL scores was determined by combining results from different studies. Component scores, adjustment for confounders, and time trends were evaluated. RESULTS Data from 57,058 patients in 31 studies were analyzed. Most studies assessed the combined effect of different SAEs. High-quality studies adjusted for preoperative QoL. When different QoL instruments were scaled down to a common 0 to 1 score, the mean difference in QoL between SAE and no-SAE patients was 0.140 in esophagectomy, 0.110 in the Crohn resection, 0.089 in colorectal resection, 0.085 in gastric bypass, 0.072 in cholecystectomy, and 0.060 in inguinal hernia repair. Studies evaluating ileal pouch formation and antireflux surgery showed conflicting results. SAEs did not significantly affect QoL in emergency laparotomy and pancreatectomy. The frequency of SAEs was 5% to 48%. Physical QoL was affected more than emotional QoL. CONCLUSIONS Significantly negative effects of SAEs on QoL were demonstrated in a range of procedures. Postoperative QoL seems to be a surrogate for the severity of impact of SAEs on patients. QoL may be an important utility to evaluate the economic and societal impact of SAEs thereby defining the threshold for safe practice.

Abstract
PURPOSE Proctocolectomy has been a curative option for patients with severe ulcerative colitis. In recent years, there has been a growing use of medical salvage therapy in the management of patients with moderate to severe ulcerative colitis. We aimed at reviewing the role of surgical management in a time of intensified medical management on the basis of published trial data. The aim was to determine the efficacy of aggressive medical versus surgical management in achieving multifaceted treatment goals. METHODS A comprehensive search of Pubmed, Medline, the Cochrane database was performed. Abstracts were evaluated for relevance. Selected articles were then reviewed in detail, including references. Recommendations were then drafted based on evidence and conclusions in the selected articles. RESULTS The majority of patients with UC will not need surgery. However, steroid-refractoriness and steroid-dependence signal a subset of patients with more challenging disease. Biological therapy has been shown to achieve short-term improvement and temporarily reduce the need for a colectomy. However, there is a substantial financial and medical price to pay because a high fraction of these salvaged patients will still need a curative colectomy but may be exposed to the negative impact of prolonged immunosuppression, chronic illness, and a higher probability to require 3 rather than 2 operations. Proctocolectomy with ileo-anal pouch anastomosis-performed in 1, 2, or 3 steps depending on the patient's condition-remains the surgical procedure of choice. Even though it has its share of possible complications, it has been associated with excellent long-term outcomes and high levels of satisfaction, such that in the majority of patients they become indistinguishable from unaffected normal individuals. CONCLUSIONS The current data demonstrate that use of medical salvage therapy in the treatment of UC will likely continue to grow and evolve. Consensus is being developed to better define and predict failure of medical therapy and clarify the role of the different treatment modalities. For many patients, sacrificing the nonresponsive diseased colon is an underused or unnecessarily delayed chance to normalize their health and life. Biologicals in many instances may have to be considered the bridge to that end.

Abstract
BACKGROUND AND AIMS We compared health-related quality of life (HRQL) and disability in ulcerative colitis (UC) patients in remission with anti-tumor necrosis factor agents (TNF) or after restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA). METHODS Two patient cohorts were studied. The first group consisted of patients in remission after RPC with IPAA (surgery group). The second group consisted of patients in remission with infliximab or adalimumab (medical group). For inclusion in the surgery group the pouch had to be functional for ≥1year and patients were excluded in case of postoperative complications. In the medical group, patients had to be on maintenance therapy with anti-TNF agents for ≥1year and in clinical remission. HRQL and disability outcomes were assessed using SF-36, COREFO, WPAI:UC and EORTC questionnaires. RESULTS 60 patients were included, 30 patients in both groups. 58 out of 60 patients (97%) returned the completed questionnaires: 29 patients in the surgery group (median age 42 years [22-67]; 48% female) and 29 patients in the medical group (median age 45 years [19-68]; 65% female). Patient characteristics were comparable between the two groups. There were no significant differences in SF-36, WPAI:UC and EORTC questionnaires between both groups, except for the medication and stool frequency scale (COREFO questionnaire) that was significantly higher in the surgery vs. the medical group (p=0.004 and p<0.001, respectively). CONCLUSION HRQL and disability were not different among the medical and surgical group, except for stool frequency and anti-diarrhea medication use that was significantly higher in surgically treated patients.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease affecting large bowel with variable clinical course. The history of disease has been modified by the introduction of biologic therapy, in particular Infliximab (IFX), that has demonstrated efficacy in inducing fast symptoms remission, promoting mucosal healing and maintaining long-term remission. However, surgery is still needed for UC patients: in case of failure of medical therapy and if acute complications or a malignancy occurred. Surgical treatment is associated with a short-term post-operative mortality and morbidity respectively of 0%-4% and 30%. In this study we systematically analyzed: the role of IFX in reducing the colectomy rate, the risk of post-operative morbidity in pre-operatively IFX-treated patients and the cost-effectiveness of IFX therapy. Four of 5 analyzed randomized controlled trials demonstrated that therapy with IFX significantly reduces the colectomy rate. Moreover, pre-operative treatment with IFX doesn’t seem to increase post-operative infectious complications. By an economic point of view, the cost-effectiveness of IFX-therapy was demonstrated for UC patients suffering from moderate to severe UC in a study based on a cost estimation of the National Health Service of England and Wales. However, the argument is debated.

Abstract
Cost-effectiveness research is a component of clinical outcomes that addresses both cost and outcomes simultaneously, providing an understanding of what incremental costs, if any, are required for better clinical outcomes. In the current health care climate, these analyses are increasingly performed, and critical, as practitioners must optimize patient care at lower costs. This review discusses cost effectiveness research, its utilization in surgical oncology, and future opportunities provided by its methodologies.

Abstract
PURPOSE Ulcerative colitis (UC) in children is frequently severe and treatment-refractory. While medical therapy is well standardized, little is known regarding factors that contribute to surgical indications. Our aim was to identify factors associated with progression to colectomy in a large cohort of pediatric UC patients. METHODS We conducted a retrospective cohort study using the Pediatric Health Information System database. We identified all patients under age 18 discharged between January 1, 2004 and September 30, 2011 with a primary diagnosis of UC. Primary outcome was odds of total colectomy. RESULTS Of 8,688 patients, 240 (2.8 %) underwent colectomy. Compared with non-operative patients, a greater proportion of colectomy patients received advanced therapies during admission, including corticosteroids (84.2 vs. 71.3 %) and biological therapy (25.4 vs. 13.6 %). Odds of colectomy were increased with malnutrition (OR 1.86), anemia (OR 2.17), electrolyte imbalance (OR 2.31), and Clostridium difficile infection (OR 1.69). TPN requirement also independently predicted colectomy (OR 3.86). Each successive UC admission significantly increased the odds of colectomy (OR 1.08). CONCLUSION These data identify factors associated with progression to colectomy in children hospitalized with UC. Our findings help to identify factors that should be incorporated into future studies aiming to reduce the variability in surgical treatment of childhood UC.

Abstract
PURPOSE OF REVIEW The field of colorectal surgery continues to move forward as technical innovations emerge and as surgeons ask critical questions. The results of subsequent investigations often lead to changes in practice. This review examines recent publications that describe these practice changes. RECENT FINDINGS We identified and reviewed recent publications in the areas of rectal cancer controversies, genetic risk profiling, practice improvements, diverticulitis, enhanced recovery protocols, fecal incontinence, and single incision laparoscopic surgery. SUMMARY New technologies and practice innovations will continue to enhance patient outcomes. Multiinstitutional studies, randomized when able, are necessary to further define the safety and efficacy of new surgical techniques and to further define best practices in colorectal surgery.
