Cost-utility of tofacitinib in the treatment of moderate-to-severe rheumatoid arthritis in France: a multi-state Markov model analysis.

OBJECTIVES: This study aimed to evaluate the cost-effectiveness of introducing tofacitinib in second-line therapies after methotrexate failure for rheumatoid arthritis in France. METHODS: Using a Markov model, we simulated a cohort of 10,000 patients based on literature data to compare various treatment strategies. The reference strategy included the four classes of biologics commonly used in France (TNFi, tocilizumab, abatacept, rituximab). The trial strategies additionally included tofacitinib at different introduction positions. The cycle duration was set at 6 months, and the time horizon was a lifetime. The data for severe adverse effects were sourced from the ORAL Surveillance study. RESULTS: Compared to the reference strategy, introducing tofacitinib is a dominant strategy, regardless of its introduction position. Introducing it as the first-line treatment results in the greatest cost savings (€1,679 per patient) while increasing quality-adjusted life years (QALYs) by 0.29. According to the one-way sensitivity analysis, the discount rate and the cost of TNFi were the two variables that most influenced costs, while the change in HAQ score and the discount rate were the two variables that most influenced QALYs. CONCLUSIONS: Our study represents the first assessment of the cost-effectiveness of tofacitinib in France and incorporates the latest adverse effects reported in the literature. It reinforces previously obtained results from other countries. Our study has some limitations, mainly related to the use of data from clinical trials. Our analysis is limited to severe adverse effects, and their cost is extrapolated from the average hospitalisation cost. The estimated costs are therefore underestimated for chronic diseases such as cancer.

The Optimal Sample Size for Usability Testing, From the Manufacturer's Perspective: A Value-of-Information Approach.

OBJECTIVES: For medical devices, a usability assessment is mandatory for market access; the objective is to detect potentially harmful use errors that stem from the device's design. The manufacturer assesses the final version of the device and determines the risk-benefit ratio for remaining errors. Nevertheless, the decision rule currently used to determine the sample size for this testing has statistical limitations and the lack of a clear decision-making perspective. METHODS: As an alternative, we developed a value-of-information analysis from the medical device manufacturer's perspective. The consequences of use errors not detected during usability testing and the errors' probability of occurrence were embedded in a loss function. The value of further testing was assessed as a reduction in the expected loss for the manufacturer. The optimal sample size was determined using the expected net benefit of sampling (ENBS) (the difference between the value provided by new participants and the cost of their inclusion). RESULTS: The value-of-information approach was applied to a real usability test of a needle-free adrenaline autoinjector. The initial estimate (performed on the first n = 20 participants) gave an optimal sample size of 100 participants and an ENBS of €255 453. This estimation was updated iteratively as new participants were included. After the inclusion of 90 participants, the ENBS was null for any sample size; hence, the cost of adding more participants outweighed the expected value of information, and therefore, the study could be stopped. CONCLUSIONS: On the basis of these results, our method seems to be highly suitable for sample size estimation in the usability testing of medical devices before market access.

Time trends in social contacts before and during the COVID-19 pandemic: the CONNECT study.

BACKGROUND: Since the beginning of the COVID-19 pandemic, many countries, including Canada, have adopted unprecedented physical distancing measures such as closure of schools and non-essential businesses, and restrictions on gatherings and household visits. We described time trends in social contacts for the pre-pandemic and pandemic periods in Quebec, Canada. METHODS: CONNECT is a population-based study of social contacts conducted shortly before (2018/2019) and during the COVID-19 pandemic (April 2020 - February 2021), using the same methodology for both periods. We recruited participants by random digit dialing and collected data by self-administered web-based questionnaires. Questionnaires documented socio-demographic characteristics and social contacts for two assigned days. A contact was defined as a two-way conversation at a distance ≤ 2 m or as a physical contact, irrespective of masking. We used weighted generalized linear models with a Poisson distribution and robust variance (taking possible overdispersion into account) to compare the mean number of social contacts over time and by socio-demographic characteristics. RESULTS: A total of 1291 and 5516 Quebecers completed the study before and during the pandemic, respectively. Contacts significantly decreased from a mean of 8 contacts/day prior to the pandemic to 3 contacts/day during the spring 2020 lockdown. Contacts remained lower than the pre-COVID period thereafter (lowest = 3 contacts/day during the Christmas 2020/2021 holidays, highest = 5 in September 2020). Contacts at work, during leisure activities/in other locations, and at home with visitors showed the greatest decreases since the beginning of the pandemic. All sociodemographic subgroups showed significant decreases of contacts since the beginning of the pandemic. The mixing matrices illustrated the impact of public health measures (e.g. school closure, gathering restrictions) with fewer contacts between children/teenagers and fewer contacts outside of the three main diagonals of contacts between same-age partners/siblings and between children and their parents. CONCLUSION: Physical distancing measures in Quebec significantly decreased social contacts, which most likely mitigated the spread of COVID-19.

Optical Coherence Tomography Contribution Assessment in the Revascularization of Long Femoropopliteal Occlusive Lesions (TASC C and D): A Randomized Trial.

BACKGROUND: Endovascular treatment has become the first-line revascularization technique for femoropopliteal lesions. This technique lacks reliable and accurate morphological control of the arterial segment treated. Intraoperative 2-dimensional angiogram consumes iodinated contrast media and increases X-ray exposure; this subsequently provides no 3-dimensional information on the quality of the revascularization completed, what could explain some of the early and late failures of the technique. We evaluated whether intraoperative optical coherence tomography (OCT) control in addition to standard angiogram could improve the primary patency rate at 12 months in comparison to standard angiogram alone in patients with occlusive femoropopliteal lesions. METHODS: The tomography by optical coherence in femoral artery trial is a multicentric, prospective, randomized, controlled, and single-blind study including patients with long de novo occlusive femoropopliteal lesions. The randomization will be achieved in 2 balanced groups of patients after crossing successfully the lesion: group 1 with intraoperative OCT control in addition to standard angiogram and group 2 with standard angiogram alone. The randomization will be stratified by center. The protocol has been submitted and approved by a French ethic's committee under reference number CPP2019-12-098. The study has been registered under the reference number NCT04434586 on the Web site of clinicaltrials.gov. RESULTS: The primary outcome of the study is the primary patency at 12 months. The number of patients who need to be treated is 166 (83 in each group) considering 5% of no workable data. Symptoms' improvement, target lesion revascularization, target vessel revascularization, quality-of-life questionnaires, cost utility, and cost effectiveness will be analyzed as secondary end-point variables at 12 months. CONCLUSIONS: The present study is to evaluate the potential benefit for patients on the result of endovascular revascularization of long occlusive femoropopliteal lesion at 12 months when using intraoperative OCT control.

Efficacy and Safety of the Duodeno-Jejunal Bypass Liner in Patients With Metabolic Syndrome: A Multicenter Randomized Controlled Trial (ENDOMETAB).

OBJECTIVE: The aim of this study was to compare the efficacy and safety of 12-month implantation of a duodeno-jejunal bypass liner (DJBL) with conventional medical care in patients with metabolic syndrome (MS). SUMMARY BACKGROUND DATA: DJBL is an endoscopic device for treating obesity and related disorders. The persistence of favorable results after 6 months has not been tested in a controlled study. METHODS: We conducted a multicenter randomized controlled trial, stratified by center and diabetes status. The primary endpoint was the remission of MS at 12 months. The secondary endpoints included body mass index (BMI), glucose control, blood pressure, and lipids, assessed at 12 months after implantation, and again, at 12 months after the removal of the DJBL. Up to 174 subjects were planned to be randomized into either the DJBL or the control arm at a 2:1 ratio, respectively. Study enrollment was discontinued by the Scientific Monitoring Committee due to the early termination of the ENDO trial (NCT01728116) by the US Food and Drug Administration. The study was terminated after withdrawal of the device's European Conformity marking by the European Medicines Agency, and an interim analysis was performed. RESULTS: A total of 82 patients were enrolled (67.5% female, 48.8% with diabetes). At 12 months after randomization, the primary endpoint was met in 6 (12%) DJBL patients and 3 (10%) controls (P = 0.72). Patients in the DJBL group experienced greater BMI loss [mean adjusted difference (95% confidence interval, CI) -3.1 kg/m (-4.4 to -1.9) kg/m, P < 0.001] and HbA1c change [mean adjusted difference -0.5% (95% CI -0.9 to -0.2); P < 0.001] than those in the control group. No difference remained statistically significant at 12 months after the removal of the DJBL. In the DJBL group, 39% of patients experienced at least one device-related serious adverse event, which was classified as Grade III Dindo-Clavien in 22%, and required premature device explantation in 16%. CONCLUSIONS: The present study showed a transient clinical benefit of DJBL, which was only apparent at 1 year, when the device was still in situ, and was obtained at the risk of serious device-related adverse events in 39% of patients. These results do not support the routine use of DJBL for weight loss and glucose control in patients with MS.

Estimating the number of usability problems affecting medical devices: modelling the discovery matrix.

BACKGROUND: Usability testing of medical devices are mandatory for market access. The testings' goal is to identify usability problems that could cause harm to the user or limit the device's effectiveness. In practice, human factor engineers study participants under actual conditions of use and list the problems encountered. This results in a binary discovery matrix in which each row corresponds to a participant, and each column corresponds to a usability problem. One of the main challenges in usability testing is estimating the total number of problems, in order to assess the completeness of the discovery process. Today's margin-based methods fit the column sums to a binomial model of problem detection. However, the discovery matrix actually observed is truncated because of undiscovered problems, which corresponds to fitting the marginal sums without the zeros. Margin-based methods fail to overcome the bias related to truncation of the matrix. The objective of the present study was to develop and test a matrix-based method for estimating the total number of usability problems. METHODS: The matrix-based model was based on the full discovery matrix (including unobserved columns) and not solely on a summary of the data (e.g. the margins). This model also circumvents a drawback of margin-based methods by simultaneously estimating the model's parameters and the total number of problems. Furthermore, the matrix-based method takes account of a heterogeneous probability of detection, which reflects a real-life setting. As suggested in the usability literature, we assumed that the probability of detection had a logit-normal distribution. RESULTS: We assessed the matrix-based method's performance in a range of settings reflecting real-life usability testing and with heterogeneous probabilities of problem detection. In our simulations, the matrix-based method improved the estimation of the number of problems (in terms of bias, consistency, and coverage probability) in a wide range of settings. We also applied our method to five real datasets from usability testing. CONCLUSIONS: Estimation models (and particularly matrix-based models) are of value in estimating and monitoring the detection process during usability testing. Matrix-based models have a solid mathematical grounding and, with a view to facilitating the decision-making process for both regulators and device manufacturers, should be incorporated into current standards.

Impact of Centralized Management of Bariatric Surgery Complications on 90-day Mortality.

BACKGROUND AND AIMS: The potential benefit of the centralization of Bariatric surgery (BS) remains debated. The aim of this study was to evaluate the impact on 90-day mortality of an innovative organization aiming at centralizing the care of severe postoperative complications of BS. STUDY DESIGN: The centralization of care for postoperative complication after BS was implemented by French Authorities in 2013 in the Nord-Pas-de-Calais Region, France. This unique formalized network (OSEAN), coordinated by 1 tertiary referral center, enrolled all regional institutions performing bariatric surgery. Data were extracted from the medico-administrative database providing information on all patients undergoing BS between 2009 and 2016 in OSEAN (n = 22,928) and in Rest of France (n = 288,942). The primary outcome was the evolution of 90-day mortality before and after the implementation of this policy. Rest of France was used as a control group to adjust the results to improvement with time of BS outcomes. RESULTS: The numbers of primary procedure and reoperations increased similarly before and after 2013 within OSEAN and in Rest of France. The 90-day mortality rate became significantly lower within OSEAN than in the rest of France after 2013 (0.03% vs 0.08%, P < 0.01). This difference was confirmed in multivariate analysis after adjustment to the procedure specific mortality (P < 0.04). The reduction of 90-day mortality was most visible for sleeve gastrectomy. CONCLUSION: The implementation of centralized care for early postoperative complications after BS in OSEAN was associated with reduced 90-day mortality. Our results indicate that this reduction was not due to a lower incidence of complications but to the improvement of their management.

Resurgence risk for measles, mumps and rubella in France in 2018 and 2020.

BackgroundLarge measles and mumps outbreaks recently occurred throughout Europe and the United States. Aim: Our aim was to estimate and map the risk of resurgence for measles, mumps and rubella in France. Methods: We used a multi-cohort model combining seroprevalence information, vaccine coverage and social contact data. Results: The overall outbreak risk for France in 2018 was highest for mumps, remained significant for measles despite a recent measles outbreak and was low for rubella. Outbreak risks were heterogeneous between departments, as the effective reproduction numbers for 2018 ranged from 1.08 to 3.66. The seroprevalence, and therefore the risk of measles and rubella infection, differed significantly between males and females. There was a lower seroprevalence, and therefore a higher risk, for males. Infants of less than 1 year would be seriously affected in a future outbreak of measles, mumps or rubella, but the highest overall caseload contribution would come from teenagers and young adults (10-25 years old). Conclusions: The high risk for teenagers and young adults is of concern in view of their vulnerability to more severe measles, mumps and rubella disease and complications.

Requests for post-registration studies (PRS), patients follow-up in actual practice: Changes in the role of databases.

Early market access of health products is associated with a larger number of requests for information by the health authorities. Compared with these expectations, the growing expansion of health databases represents an opportunity for responding to questions raised by the authorities. The computerised nature of the health system provides numerous sources of data, and first and foremost medical/administrative databases such as the French National Inter-Scheme Health Insurance Information System (SNIIRAM) database. These databases, although developed for other purposes, have already been used for many years with regard to post-registration studies (PRS). The use thereof will continue to increase with the recent creation of the French National Health Data System (SNDS [2016 health system reform law]). At the same time, other databases are available in France, offering an illustration of "product use under actual practice conditions" by patients and health professionals (cohorts, specific registries, data warehouses, etc.). Based on a preliminary analysis of requests for PRS, approximately two-thirds appeared to have found at least a partial response in existing databases. Using these databases has a number of disadvantages, but also numerous advantages, which are listed. In order to facilitate access and optimise their use, it seemed important to draw up recommendations aiming to facilitate these developments and guarantee the conditions for their technical validity. The recommendations drawn up notably include the need for measures aiming to promote the visibility of research conducted on databases in the field of PRS. Moreover, it seemed worthwhile to promote the interoperability of health data warehouses, to make it possible to match information originating from field studies with information originating from databases, and to develop and share algorithms aiming to identify criteria of interest (proxies). Methodological documents, such as the French National Authority for Health (HAS) recommendations on "Les études post-inscription sur les technologies de santé (médicaments, dispositifs médicaux et actes). Principes et méthodes" [Post-registration studies on health technologies (medicinal products, medical devices and procedures). Principles and methods] should be updated to incorporate these developments.

What is the budget impact of a new treatment or new health technology arriving on the market?

In France, market access for innovative drugs (level I, II & III improvement of medical service rendered having significant impact on health insurance expenditure) involves medico-economic evaluation. In addition to cost-effectiveness analysis (CEA), budget impact analysis (BIA) can be performed, especially since the sustainability of the health insurance system has become a growing concern for all stakeholders. The members of the Giens 2016 round table discussed the contribution of BIA based on a review of the literature on distribution models, the participants' experiences including experience related to the modalities of hospital assessments, and examples from other countries. The round table established recommendations on four elements of interest: 1: the use of BIA from a contractual point of view - between manufacturers and the French Economic Committee for Health Products - during the price negotiations process, and from a prospective point of view within the framework of the annual review of budget expenditures; the definition of the target population and the rhythm of a health product's distribution are also major elements; 2: the interpretation of BIA results in light of CEA results: for what products and at what moment in the life cycle of these products; 3: the integration of the rhythm of a health product's distribution into the BIA; 4: preoccupations about how the level of health product implementation is integrated into the BIA in terms of opportunity cost and organisational quality for the promoter.

Assessment and non-clinical impact of medical devices.

Medical devices (MDs) cover a wide variety of products. They accompany changes in medical practice in step with technology innovations. Innovations in the field of MDs can improve the conditions of use of health technology and/or modify the organisation of care beyond the strict diagnostic or therapeutic benefit for the patients. However, these non purely clinical criteria seem to be only rarely documented or taken into account in the assessment of MDs during reimbursement decisions at national level or for formulary listing by hospitals even though multidimensional models for the assessment of health technologies have been developed that take into account the views of all stakeholders in the healthcare system In this article, after summarising the background concerning the assessment of health technologies in France, a definition of non-clinical criteria for the assessment of MDs is proposed and a decision tree for the assessment of MDs is described. Future lines of approach are proposed as a conclusion.

Social participation in patients with multiple sclerosis: correlations between disability and economic burden.

BACKGROUND: Economic costs related to treatment of multiple sclerosis (MS) must be justified by health state, quality of life (QOL) and social participation improvement. This study aims to describe correlations between social participation, economic costs, utility and MS-specific QOL in a sample of patients with MS (pwMS). METHODS: We interviewed 42 pwMS receiving natalizumab and collected clinical data, direct medical costs, productivity loss, utility (EQ5D-VAS), MS-specific QOL (SEP-59), social participation with the Impact on Participation and Autonomy questionnaire (IPA). We performed descriptive and correlation analyses. RESULTS: 41 pwMS, with a mean Expanded Disability Status Scale (EDSS) score of 4.0, completed questionnaires. Mean annual global cost per patient was 68448 +/-33374 Euros and increased with EDSS (r = 0.644), utility (r = -0.456) and IPA (r = 0.519-0.671) worsening. Mean utility was 0.52 +/- 0.28. Correlations between IPA and QOL (EQ5D-VAS or SEP-59) were observed (r = -0.53 to -0.78). Association between QOL and EDSS was smaller (EQ5D-VAS) or absent. Productivity losses were poorly correlated to EDSS (r = 0.375). CONCLUSION: Moderate to strong correlations of social participation with clinical status (EDSS), QOL, utility and economic costs encourage exploring better these links in larger cohorts. The stronger correlation between social participation and QOL than between EDSS and QOL needs to be confirmed.

Medico-economic evaluation of healthcare products. Methodology for defining a significant impact on French health insurance costs and selection of benchmarks for interpreting results.

Decree No. 2012-1116 of 2 October 2012 on medico-economic assignments of the French National Authority for Health (Haute autorité de santé, HAS) significantly alters the conditions for accessing the health products market in France. This paper presents a theoretical framework for interpreting the results of the economic evaluation of health technologies and summarises the facts available in France for developing benchmarks that will be used to interpret incremental cost-effectiveness ratios. This literature review shows that it is difficult to determine a threshold value but it is also difficult to interpret then incremental cost effectiveness ratio (ICER) results without a threshold value. In this context, round table participants favour a pragmatic approach based on "benchmarks" as opposed to a threshold value, based on an interpretative and normative perspective, i.e. benchmarks that can change over time based on feedback.

Medico-economic evaluation of health products in the context of the Social Security Financing Act for 2012.

The participants in round table 6 of the Giens Workshops 2012 drafted recommendations based on the collective interpretation of important elements of the decree concerning the medico-economic evaluation of health products published a few days earlier (02 October 2012). The medico-economic evaluation (MEE), becomes an additional determinant for fixing the prices of health products by the Health products economic committee (Comité économique des produits de santé, CEPS) via the hierarchisation of treatment strategies, and thus modifies the market access conditions. Limiting the analysis to medicinal products and medical devices for which a major, important or moderate improvement in the medical service rendered (ASMR) or of the expected service (ASA) has been requested and presenting a significant budget impact on the Social Security expenses, excludes health products with ASMR or ASA with a lower level requested which often create complex price fixing problems and often have a major budget impact. This latter concept remains to be defined in detail. The MEE envisaged for the first registration must include the need to confirm or refute the initial hypotheses especially concerning the actual position in the therapeutic strategy at the time of renewal of the registration. For the first registration, the conventional reference to European prices guaranteeing a minimum price to innovative medicinal products, the medico-economic models submitted by the industry to the French Drug Authority (Haute autorité de santé, HAS) must be used to guide the compilation of new data to be requested at the time of the registration renewal and to negotiate the level of the discounts in the framework of a price-volume agreement, if applicable. The MEE will allow comparing the result of the analysis to the model hypothesis at the time of the renewal of the registration, which may contribute to the renegotiation (either up or down) of the price of health goods. The costs related to obtaining new data must be controlled. In order for the MEE to allow confirming the relationship between the price requested and the benefit expected, the group privileges the definition of reference values with an indicative and non-normative value, likely to evolve with time rather than a threshold. Concerning the evaluation procedure: the time to market access must not be lengthened; while the possibility of regular meetings between the industry and the HAS is recommended to avoid methodological divergences. A transitory period should allow the implementation of the entire evaluation procedure which must also take into account the specificities of health products registered before the 3 October 2013.

Impact of RSV test positivity, patient characteristics, and treatment characteristics on the cost of hospitalization for acute bronchiolitis in a French university medical center (2010-2015).

Background: In young children, respiratory syncytial virus (RSV)-related bronchiolitis is typically more severe than other respiratory tract infections, with a greater need for oxygen therapy and respiratory support. Few studies have compared the cost of hospitalization with regard to virological status. The objective of this study was to compare the costs of hospitalization for RSV-positive vs. RSV-negative bronchiolitis in a French university medical center between 2010 and 2015. Methods: The cost models were compared using conventional goodness-of-fit criteria. Covariates included the characteristics of the patients, pre-existing respiratory and non-respiratory comorbidities, superinfections, medical care provided, and the length of stay. Results: RSV was detected in 679 (58.3%) of the 1,164 hospital stays by children under 2 years with virological data. Oxygen therapy and respiratory support were twice as frequent for the RSV-positive cases. The median hospitalization cost was estimated at €3,248.4 (interquartile range: €2,572.1). The cost distribution was positively skewed with a variation coefficient (CV = standard deviation/mean) greater than one (mean = €4,212.9, standard deviation = €5,047, CV = 1.2). In univariate analyses, there was no significant cost difference between the RSV-positive and RSV-negative cases. In the best multivariate model, the significant positive effect of RSV positivity on cost waned after the introduction of medical care variables and the length of stay. The results were sensitive to the specification of the model. Conclusions: It was impossible to firmly conclude that hospitalization costs were higher for the RSV-positive cases.

Real-world data and evidence in health technology assessment: When are they complementary, substitutes, or the only sources of data compared to clinical trials?

Within the life-cycle assessment of health technologies, real-world data (RWD) have until now been of secondary importance to clinical trial data. The availability of massive, better quality RWD, particularly with the emergence of connected devices, the improvement of methods for characterizing populations, make it possible to have a better insight into the effects of treatment, sometimes on a national scale the importance of RWD is likely to progress in the eyes of health technology assessors, going from being traditionally complementary to possibly replacing clinical trial data. This is the fundamental question that the round table, involving experts from the academic and/or hospital, institutional, and industrial worlds, set out to answer. This work served first to establish the current role of RWD in health technology assessment, by distinguishing the main purposes of RWD, the timing of the evaluation in relation to the life cycle of the technology, and then according to the party commissioning or receiving the outcomes of RWD-based studies. Secondly, the round table proposed six general recommendations for more intensive and decisive use of RWD in the assessment and decision-making process.

Economic burden and health-related quality-of-life among infants with respiratory syncytial virus infection: A multi-country prospective cohort study in Europe.

BACKGROUND: Respiratory syncytial virus (RSV) causes a considerable disease burden in young children globally, but reliable estimates of RSV-related costs and health-related quality-of-life (HRQoL) are scarce. This study aimed to evaluate the RSV-associated costs and HRQoL effects in infants and their caregivers in four European countries. METHODS: Healthy term-born infants were recruited at birth and actively followed up in four European countries. Symptomatic infants were systematically tested for RSV. Caregivers recorded the daily HRQoL of their child and themselves, measured by a modified EQ-5D with Visual Analogue Scale, for 14 consecutive days or until symptoms resolved. At the end of each RSV episode, caregivers reported healthcare resource use and work absenteeism. Direct medical costs per RSV episode were estimated from a healthcare payer's perspective and indirect costs were estimated from a societal perspective. Means and 95% confidence intervals (CI) of direct medical costs, total costs (direct costs + productivity loss) and quality-adjusted life-day (QALD) loss per RSV episode were estimated per RSV episode, as well as per subgroup (medical attendance, country). RESULTS: Our cohort of 1041 infants experienced 265 RSV episodes with a mean symptom duration of 12.5 days. The mean (95% CI) cost per RSV episode was €399.5 (242.3, 584.2) and €494.3 (317.7, 696.1) from the healthcare payer's and societal perspective, respectively. The mean QALD loss per RSV episode of 1.9 (1.7, 2.1) was independent of medical attendance (in contrast to costs, which also differed by country). Caregiver and infant HRQoL evolved similarly. CONCLUSION: This study fills essential gaps for future economic evaluations by prospectively estimating direct and indirect costs and HRQoL effects on healthy term infants and caregivers separately, for both medically attended (MA) and non-MA laboratory-confirmed RSV episodes. We generally observed greater HRQoL losses than in previous studies which used non-community and/or non-prospective designs.

Outcome and cost analysis of sacral nerve modulation for treating urinary and/or fecal incontinence.

BACKGROUND: Sacral nerve modulation (SNM) is an established treatment for urinary and fecal incontinence in patients for whom conservative management has failed. OBJECTIVE: This study assessed the outcome and cost analysis of SNM compared to alternative medical and surgical treatments. METHODS: Clinical outcome and cost-effectiveness analyses were performed in parallel with a prospective, multicenter cohort study that included 369 consecutive patients with urge urinary and/or fecal incontinence. The duration of follow-up was 24 months, and costs were estimated from the national health perspective. Cost-effectiveness outcomes were expressed as incremental costs per 50% of improved severity scores (incremental cost-effectiveness ratio). RESULTS: The SNM significantly improved the continence status (P < 0.005) and quality of life (P < 0.05) of patients with urge urinary and/or fecal incontinence compared to alternative treatments. The average cost of SNM for urge urinary incontinence was ∈8525 (95% confidence interval, ∈6686-∈10,364; P = 0.001) more for the first 2 years compared to alternative treatments. The corresponding increase in cost for subjects with fecal incontinence was ∈6581 (95% confidence interval, ∈2077-∈11,084; P = 0.006). When an improvement of more than 50% in the continence severity score was used as the unit of effectiveness, the incremental cost-effectiveness ratio for SNM was ∈94,204 and ∈185,160 at 24 months of follow-up for urinary and fecal incontinence, respectively. CONCLUSIONS: The SNM is a cost-effective treatment for urge urinary and/or fecal incontinence.
