Objective. To assess by simulation the cost-effectiveness of intrathecal baclofen (ITB) therapy compared with conventional medical treatments for patients with disabling spasticity and functional dependence caused by any neurological disease. Methods. Two models were created to simulate therapeutic strategies for managing severe spasticity, one with and one without the use of ITB, to assess various treatment sequences over 2 years based on current medical practices in France. Successful treatment at each evaluation was defined as a combination of: (1) the increased patient and caregiver satisfaction as assessed by goal attainment scaling (GAS), and (2) a decrease of at least 1 point on the Ashworth score. Probabilistic sensitivity analyses were performed using 5000 Monte-Carlo simulations taking into account specific distribution curves for direct costs and effectiveness parameters in each treatment option. Results. The model simulations suggest that including ITB as a first option strategy in the management of function of severely impaired patients with disabling spasticity results in a higher success rate (78.7% vs 59.3%; P < .001). In addition, the ITB therapy model revealed a lower cost (59 391 vs 88 272; P < .001) and an overall more favorable cost-effectiveness ratio (75 204/success vs 148 822/success; P < .001), compared with conventional medical management without ITB. Conclusion. Within the assumptions of our modeling, ITB therapy evaluated by a combination of treatment success criteria at 6-month intervals over a 2-year period may be a cost-effective strategy compared to conventional medical management alone.

Objectives The aim of this study was to investigate potential statistical relationships between black tea consumption and key health indicators in the world. The research question is: Does tea consumption is correlated with one or more epidemiological indicators? Design Ecological study using a systematic data-mining approach in which the unit of the analysis is a population of one country. Setting Six variables, black tea consumption data and prevalence data of respiratory diseases, infectious diseases, cancer, cardiovascular diseases and diabetes, have been studied at a global level. Participants Data from 50 participating countries in the World Health Survey were investigated. Primary and secondary outcomes measures Level of statistical relationships between variables. Results Principal component analysis established a very high contribution of the black tea consumption parameter on the third axis (81%). The correlation circle confirmed that the ‘black tea’ vector was negatively correlated with the diabetes vector and was not correlated with any of the other four health indicators. A linear correlation model then confirmed a significant statistical correlation between high black tea consumption and low diabetes prevalence. Conclusions This innovative study establishes a linear statistical correlation between high black tea consumption and low diabetes prevalence in the world. These results are consistent with biological and physiological studies conducted on the effect of black tea on diabetes and confirm the results of a previous ecological study in Europe. Further epidemiological research and randomised studies are necessary to investigate the causality.

Background: Data from clinical trials comparing Helicobacter pylori (H. pylori) management strategies in patients with dyspepsia are limited. Cost‐effectiveness simulation models might help to identify the optimal strategy.Objective: To assess the cost‐effectiveness of the H. pylori "Test and Treat" (T&T) strategy including the use of urea breath test (UBT) vs symptomatic treatment (ST) and vs upper gastrointestinal endoscopy (UGE) as a first procedure in patients with dyspepsia.Methods: Three main strategies: “T&T” strategy including the use of UBT, "UGE" and "ST" have been compared using cost‐effectiveness models developed in accordance with the Spanish medical practice. For the model simulations, a time horizon of 4 weeks was considered for the endpoint "Dyspepsia symptoms relief" and 10 years when using "Peptic ulcer avoided" and "Gastric cancer avoided" endpoints.Results: For the endpoint "Dyspepsia symptoms relief", T&T strategy appears to be the most cost‐effective (883€/success) compared to UGE strategy and to ST strategy (respectively 1628€ and 990€/success). For the endpoint "Probability of peptic ulcer", the T&T strategy appears to be the most cost‐effective (421€/peptic ulcer avoided/y) compared to UGE strategy and ST strategy (respectively 728€ and 632€/peptic ulcer avoided/y). For the endpoint "Gastric cancer avoided", the T&T strategy appears to be the most cost‐effective (524€/gastric cancer avoided/y) compared to UGE strategy and "ST" strategy (respectively 716€ and 696€/gastric cancer avoided/y).Conclusions: T&T strategy including the use of UBT is the most cost‐effective medical approach for management of dyspepsia and for the prevention of ulcer and gastric cancer.

Background. The objective of this simulation model was to assess the cost-effectiveness of different biological treatment strategies based on levels of disease activity in Spain, in patients with moderate to severe active RA and an insufficient response to at least one anti-TNF agent.Methods. Clinically meaningful effectiveness criteria were defined using DAS28 scores: remission and Low Disease Activity State (LDAS) thresholds. Monte-Carlo simulations were conducted to assess cost-effectiveness over 2 years of four biological sequential strategies composed of anti-TNF agents (adalimumab, infliximab), abatacept or rituximab, in patients with moderate to severe active RA and an insufficient response to etanercept as first biological agent.Results. The sequential strategy including etanercept, abatacept and adalimumab appeared more efficacious over 2 years (102 days in LDAS) compared to the same sequence including rituximab as second biological option (82 days in LDAS). Cost-effectiveness ratios showed lower costs per day in LDAS with abatacept (427 €) compared to rituximab as second biological option (508 €). All comparisons were confirmed when using remission criteria.Conclusion. Model results suggest that in patients with an insufficient response to anti-TNF agents, the biological sequences including abatacept appear more efficacious and cost-effective than similar sequences including rituximab or cycled anti-TNF agents.
