Two thirds were randomized to active care(6 mo colonoscopy and drug intensification for endoscopic recurrence) and one third to drug therapy without early endoscopy. Colonoscopy at 18 mo and faecal calprotectin(FC) measurement were used to assess disease recurrence. Administrative data, chart review and patient questionnaires were collected prospectively over 18 mo.RESULTS: Sixty patients(active care n = 43, standardcare n = 17) were included from one health service. Median total health care cost was $6440 per patient. Active care cost $4824 more than standard care over 18 mo. Medication accounted for 78% of total cost, of which 90% was for adalimumab. Median health care cost was higher for those with endoscopic recurrence compared to those inremission [ $ 26347( IQR 25045-27485) vs $2729(IQR 1182-5215), P < 0.001]. FC to select patients for colonoscopy could reduce cost by $1010 per patient over 18 mo. Active care was associated with 18% decreased endoscopic recurrence, costing $861 for each recurrence prevented. CONCLUSION: Post-operative management strategies are associated with high cost, primarily medication related. Calprotectin use reduces costs. The long term cost-benefit of these strategies remains to be evaluated.展开更多

Prevalence of work disability was assessed in 2794 IBD patients and compared with the general Dutch population. Multivariate analyses were performed for work disability(sick leave, partial and full disability) and long-term full work disability(> 80% work disability for > 2 years).RESULTS Prevalence of work disability was higher in Crohn's disease(CD)(29%) and ulcerative colitis(UC)(19%) patients compared to the general Dutch population(7%). In all IBD patients, female sex, a lower education level, and extra-intestinal manifestations, were associated with work disability. In CD patients, an age > 40 years at diagnosis, disease duration > 15 years,smoking, surgical interventions, and anti-TNFα use were associated with work disability. In UC patients, an age > 55 years, and immunomodulator use were associated with work disability. In CD patients, a lower education level(OR = 1.62, 95%CI: 1.02-2.58), and in UC patients, disease complications(OR = 3.39, 95%CI: 1.09-10.58) were associated with long-term full work disability.CONCLUSION The prevalence of work disability in IBD patients is higher than in the general Dutch population. Early assessment of risk factors for work disability is necessary, as work disability is substantial among IBD patients.展开更多

Methods: Data were obtained from the Centers for Medicareand Medicaid Services (CMS). Individuals enrolled in Florida,New Jersey, and New York Medicaid programs on January 1, 2004, remained in that program for 1 year and exposed to an AD medication were included. AD diagnosis was based on the ICD-9-CM code 331.0. Outcomes of interest were hospitalization and institutionalization. Multivariate logistic regression models were used to test for the association between outcomes of interest and demographics, resource utilization factors, and type of AD pharmacotherapy exposure. Results: A total of 65,442 individuals qualified for the study. Age was positively and significantly associated with hospitalization (p likely to be hospitalized than Florida residents (OR = 1.30;99% CI: 1.17 - 1.44), where as New Jersey residents were significantly less likely to be hospitalized (OR = 0.75;99% CI: 0.66 - 0.85). Finally, compared toFloridaresidents, residents of New Jerseywere significantly more likely to be institutionalized (OR = 4.61;99% CI: 3.98 - 5.33). Conclusion: Demographics, state of residence and pharmacotherapy exposure weresignificant predictors of health care service utilization. Further pharmacoeconomic studies in AD medication therapy are warranted.展开更多

The disease is progressive and irreversible, with an average time course of 8 to 10 years. Regardless of catastrophic forecasts for the next decades, its actual prevalence has huge family and social costs.展开更多
