RESUMO
BACKGROUND: The cost effectiveness of childhood varicella vaccination is uncertain, as evidenced by variation in national health policies. Within the European Economic Area (EEA), only 10 of 30 countries offer universally funded childhood varicella vaccination. This study estimates the cost effectiveness of universal childhood varicella vaccination for one EEA country (Ireland), highlighting the difference in cost effectiveness between alternative vaccination strategies. METHODS: An age-structured dynamic transmission model, simulating varicella zoster virus transmission, was developed to analyse the impact of three vaccination strategies; one-dose at 12 months old, two-dose at 12 and 15 months old (short-interval), and two-dose at 12 months and five years old (long-interval). The analysis adopted an 80-year time horizon and considered payer and societal perspectives. Clinical effectiveness was based on cases of varicella and subsequently herpes zoster and post-herpetic neuralgia avoided, and outcomes were expressed in quality-adjusted life-years (QALYs). Costs were presented in 2022 Irish Euro and cost effectiveness was interpreted with reference to a willingness-to-pay threshold of 20,000 per QALY gained. RESULTS: From the payer perspective, the incremental cost-effectiveness ratio (ICER) for a one-dose strategy, compared with no vaccination, was estimated at 8,712 per QALY gained. The ICER for the next least expensive strategy, two-dose long-interval, compared with one-dose, was estimated at 45,090 per QALY gained. From a societal perspective, all three strategies were cost-saving compared with no vaccination; the two-dose short-interval strategy dominated, yielding the largest cost savings and health benefits. Results were stable across a range of sensitivity and scenario analyses. CONCLUSION: A one-dose strategy was highly cost effective from the payer perspective, driven by a reduction in hospitalisations. Two-dose strategies were cost saving from the societal perspective. These results should be considered alongside other factors such as acceptability of a new vaccine within the overall childhood immunisation schedule, programme objectives and budget impact.

AIM: To systematically identify and appraise the international literature on the cost-effectiveness of metabolic surgery for the treatment of comorbid type 2 diabetes (T2D) and obesity. METHODS: A systematic search was conducted in electronic databases and grey literature sources up to 20 January 2021. Economic evaluations in a T2D population or a subpopulation with T2D were eligible for inclusion. Screening, data extraction, critical appraisal of methodological quality (Consensus Health Economic Criteria list) and assessment of transferability (International Society for Pharmacoeconomics and Outcomes Research questionnaire) were undertaken in duplicate. The incremental cost-effectiveness ratio (ICER) was the main outcome. Costs were reported in 2020 Irish Euro. Cost-effectiveness was interpreted using willingness-to-pay (WTP) thresholds of 20,000 and 45,000/quality-adjusted life year (QALY). Due to heterogeneity arising from various sources, a narrative synthesis was undertaken. RESULTS: Thirty studies across seventeen jurisdictions met the inclusion criteria; 16 specifically in a T2D population and 14 in a subpopulation with T2D. Overall, metabolic surgery was found to be cost-effective or cost-saving. Where undertaken, the results were robust to sensitivity and scenario analyses. Of the 30 studies included, 15 were considered high quality. Identified limitations included limited long-term follow-up data and uncertainty regarding the utility associated with T2D remission. CONCLUSION: Published high-quality studies suggest metabolic surgery is a cost-effective or cost-saving intervention. As the prevalence of obesity and obesity-related diseases increases worldwide, significant investment and careful consideration of the resource requirements needed for metabolic surgery programmes will be necessary to ensure that service provision is adequate to meet demand.

All EU countries have introduced Human papilloma virus (HPV) vaccination for adolescent girls and many countries are expanding the strategy to include adolescent boys. There is uncertainty about the cost-effectiveness and epidemiological impact of a gender-neutral HPV vaccination strategy. Here we present the results of an economic model adapted for Spain. Five vaccination strategies were compared from the Spanish healthcare system perspective, combining two vaccines (4-valent and 9-valent) in a gender-neutral or girls-only programme in a dynamic population-based model with a discrete-time Markov approach. Costs and benefits were discounted at 3%. The benefits of immunization were measured with quality-adjusted life years (QALYs), which are achieved by reducing the incidence of diseases attributable to HPV. Incremental cost-effectiveness ratio (ICER) was compared with the willingness-to-pay threshold in Spain. The two most effective strategies were compared: gender-neutral 9-valent vaccination vs. girls-only 9-valent vaccination, resulting in an ICER of 34,040/QALY, and an important number of prevented cases of invasive cancers and anogenital warts. The sensitivity analysis revealed that gender-neutral 9-valent vaccination would become cost-effective if protection against oropharyngeal and penile cancers was included or if the price per dose decreased from 45 to 28. The gender-neutral 9-valent HPV vaccination in Spain offers more benefits than any other modeled strategy, although in the conservative base case it is not cost-effective. However, certain plausible assumptions would turn it into an efficient strategy, which should be borne in mind by the decision makers together with equity and justice arguments.
What is the context? Human papillomavirus (HPV) is a group of viruses that causes sexually transmitted diseases, including certain cancers. European countries offer HPV vaccination to adolescent girls.Many countries have also introduced the vaccination in adolescent boys.There are doubts about whether it is worth vaccinating adolescents of both genders.What this study adds? We estimated costs and benefits of the vaccination in Spain, comparing two types of vaccine, only in girls and in both genders. This analysis considered indirect protection of vaccinated people to unvaccinated ones.It seems that the benefits of HPV vaccination in all adolescents do not compensate the costs.However, when we included likely protection against additional cancers or we reduced the price per vaccine dose, it would be worth vaccinating all adolescents in Spain.We also stated ethical arguments in favor of HPV vaccination for both genders.What is the impact? HPV vaccination in adolescent boys and girls in Spain will prevent more HPV-related diseases.For certain scenarios, HPV vaccination in both genders would be worth in Spain.Ethically, vaccinating also boys would be fair, equitable and would not discriminate a part of the population.

Out-of-hospital cardiac arrest (OHCA) is a leading cause of death worldwide. Without appropriate early resuscitation interventions, the prospect of survival is limited. This means that an effective community response is a critical enabler of increasing the number of people who survive. However, while OHCA incidence is higher in more deprived areas, propensity to volunteer is, in general, associated with higher socioeconomic status. In this context, we consider whether there are socioeconomic disparities in geographic accessibility to volunteer community first responders (CFRs) in Ireland, where CFR groups have developed organically and communities self-select to participate. We use geographic information systems and propensity score matching to generate a set of control areas with which to compare established CFR catchment areas. Differences between CFRs and controls in terms of the distribution of catchment deprivation and social fragmentation scores are assessed using two-sided Kolmogorov-Smirnov tests. Overall we find that while CFR schemes are centred in more deprived and socially fragmented areas, beyond a catchment of 4 min there is no evidence of differences in area-level deprivation or social fragmentation. Our findings show that self-selection as a model of CFR recruitment does not lead to more deprived areas being disadvantaged in terms of access to CFR schemes. This means that community-led health interventions can develop to the benefit of community members across the socioeconomic spectrum and may be relevant for other countries and jurisdictions looking to support similar models within communities.
RESUMO
OBJECTIVES: We aimed to evaluate the cost-effectiveness of offering once-off birth cohort testing for hepatitis C virus (HCV) to people in Ireland born between 1965 and 1985, the cohort with the highest reported prevalence of undiagnosed chronic HCV infection. METHODS: Systematic and opportunistic HCV birth cohort testing programs, implemented over a 4-year timeframe, were compared with the current practice of population risk-based testing only in a closed-cohort decision tree and Markov model hybrid over a lifetime time horizon. Outcomes were expressed in quality-adjusted life-years (QALYs). Costs were presented from the health system's perspective in 2020 euro (). Uncertainty was assessed via deterministic, probabilistic, scenario, and threshold analyses. RESULTS: In the base case, systematic testing yielded the largest cost and health benefits, followed by opportunistic testing and risk-based testing. Compared with risk-based testing, the incremental cost-effectiveness ratio for opportunistic testing was 14 586 (95% confidence interval 4185-33 527) per QALY gained. Compared with opportunistic testing, the incremental cost-effectiveness ratio for systematic testing was 16 827 (95% confidence interval 5106-38 843) per QALY gained. These findings were robust across a range of sensitivity analyses. CONCLUSIONS: Both systematic and opportunistic birth cohort testing would be considered an efficient use of resources, but systematic testing was the optimal strategy at willingness-to-pay threshold values typically used in Ireland. Although cost-effective, any decision to introduce birth cohort testing for HCV (in Ireland or elsewhere) must be balanced with considerations regarding the feasibility and budget impact of implementing a national testing program given high initial costs and resource use.

Rapid antigen detection tests (RADTs) offer advantages over gold-standard reverse transcription polymerase chain reaction (RT-PCR) tests in that they are cheaper and provide faster results, thus enabling prompt isolation of positive SARS-CoV-2 cases and quarantine of close contacts. The aim of this study was to collate and synthesise empirical evidence on the effectiveness of rapid antigen testing for the screening (including serial testing) and surveillance of asymptomatic individuals to limit the transmission of SARS-CoV-2. A rapid review was undertaken in MEDLINE (EBSCO), EMBASE (OVID), Cochrane Library, Europe PMC and Google Scholar up until 19 July 2021, supplemented by a grey literature search. Of the identified 1222 records, 19 reports referring to 16 studies were included. Eight included studies examined the effectiveness of RADTs for population-level screening, four for pre-event screening and four for serial testing (schools, a prison, a university sports programme and in care homes). Overall, there is uncertainty regarding the effectiveness of rapid antigen testing for the screening of asymptomatic individuals to limit the transmission of SARS-CoV-2. This uncertainty is due to the inconsistent results, the relatively low number of studies identified, the predominantly observational and/or uncontrolled nature of the study designs used, and concerns regarding methodological quality. Given this uncertainty, more real-world research evidence in relevant settings, which is of good quality and timely, as well as economic evaluation, is required to inform public policy on the widespread use of RADTs in asymptomatic individuals.

BACKGROUND AND OBJECTIVES: Recognising the significant public health threat posed by hepatitis C, international targets have been established by the World Health Organization with the aim of eradicating the hepatitis C virus (HCV) by 2030. With the availability of safe and effective therapies, the greatest challenge to achieving elimination is the identification and treatment of those currently undiagnosed. This systematic review aimed to identify and appraise the international literature on the cost-effectiveness of birth cohort, universal, and age-based general population testing for identifying people with undiagnosed chronic HCV infection. METHODS: A comprehensive literature search was undertaken in Medline, Embase and grey literature sources to identify studies published between 1 January 2000 and 17 July 2020. Retrieved citations were independently reviewed by two reviewers according to pre-defined eligibility criteria. Data extraction and critical appraisal were completed in duplicate. Study quality, relevance and credibility were assessed using the Consensus for Health Economic Criteria and the ISPOR questionnaires. All costs were reported in 2019 Irish Euro following adjustment for inflation and purchasing power parity. Willingness-to-pay (WTP) thresholds of 20,000 and 45,000 were adopted as reference points for interpreting cost-effectiveness in the narrative synthesis. The systematic review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. RESULTS: Overall, 4622 citations were retrieved in the literature search. Of these, 27 studies met the inclusion criteria. Six (22%) of the 27 studies were rated as low quality, 17 (63%) were moderate quality and four (15%) were high quality. Compared with no testing or risk-based testing: 14 of 16 (88%) cost-utility analyses found that birth cohort testing was cost effective, eight of nine (89%) analyses found that universal testing was cost effective, and eight of eight (100%) analyses found that age-based general population testing was cost effective. Cost effectiveness was influenced by disease prevalence and progression, testing and treatment uptake, treatment eligibility of those identified by testing, the cost of treatment and the proportion of those treated that achieve sustained virological response. CONCLUSION: Overall, the international evidence supports the potential cost effectiveness of birth cohort, universal, and age-based general population testing, but is caveated by study generalisability, specifically the transferability of findings from one jurisdiction to another, and institutional variations in healthcare delivery systems and budgetary constraints. The cost effectiveness of each approach will vary according to population- and health system-specific characteristics such as epidemiological context, testing coverage, linkage to care and capacity to treat. Given issues regarding the transferability of economic evaluations (for example, model inputs and assumptions) and the significant resources required to implement these interventions, jurisdiction-specific economic evaluations and budget impact analyses will likely be required to inform investment and implementation decisions.

BACKGROUND: Approximately 60% of antibiotics issued in primary care are for acute respiratory tract infections (RTIs), which are largely self-limiting and do not require antibiotics. Point-of-care testing (POCT) devices that measure C-reactive protein (CRP)-a biomarker for infection-can be used to guide prescribing decisions. OBJECTIVE: We evaluated the cost-effectiveness and budget impact of a national CRP POCT program to guide antibiotic prescribing for acute RTIs in primary care in Ireland. METHODS: We compared CRP POCT with and without enhanced communication skills training of general practitioners against usual care. A probabilistic decision tree was used to investigate cost-effectiveness from the perspective of the healthcare system. The model considered outcomes for the Irish population over a 5-year time horizon. Inputs were synthesized from published studies. Cost-effectiveness was estimated using an incremental cost per prescription avoided. RESULTS: CRP POCT with and without communication training were more costly but more effective than usual care over 5 years. CRP POCT alone was dominated, while the combined intervention had a cost per prescription avoided of 111 (95% CI: 45-243) versus usual care. The budget impact was costly over 5 years, but potential budget savings were available depending on the implementation scenario. The findings were largely robust to sensitivity analyses. CONCLUSIONS: CRP POCT reduces antibiotic prescribing, but increases healthcare costs. The most cost-effective program of CRP POCT includes enhanced communication skills training. Further research on the impact of CRP POCT beyond 5 years is warranted, as well as the potential impact on antimicrobial resistance.

OBJECTIVES: To estimate the cost-effectiveness of introducing a publicly funded pre-exposure prophylaxis (PrEP) program in Ireland. METHODS: We constructed a state-transition Markov model. This was a cross-sectional population model that tracked all HIV-negative men who have sex with men (MSM) in Ireland over their lifetime. Access to a publicly funded PrEP program (medications + frequent monitoring) in high-risk MSM was compared with no PrEP. The primary outcome measure was the incremental cost-effectiveness ratio (ICER). RESULTS: In the base case, introducing a PrEP program was considered cost saving and provided significant health benefits to the population. Univariate sensitivity analysis demonstrated that PrEP efficacy and HIV incidence had the greatest impact on cost-effectiveness. Including an increase in sexually transmitted infections had a negligible impact on the results. Efficacy was a significant driver in the model. PrEP was cost saving at all efficacy values above 60%, and at the lowest reported efficacy in MSM (44% in the iPrEX trial), the ICER was 4711/QALY (highly cost-effective). Event-based dosing (administration during high-risk periods only) was associated with additional cost savings. We estimated that 1705 individuals (95% CI: 617-3452) would join the program in year 1. The incremental budget impact was 1.5m (95% CI: 0.5m to 3m) in the first year and 5.4m over 5 years (95% CI: 1.8m to 11.5m), with 173 cases of HIV averted over 5 years. CONCLUSION: We found that the introduction of a PrEP program would be considered cost saving in the first cost-effectiveness analysis of its kind in Ireland.

This commentary considers the positive and negative consequences of early economic modelling and explores potential future directions. Early economic modelling offers device manufacturers an opportunity to assess the potential value of an innovation at an early stage of development. Early modelling can direct resources into potentially viable technologies and reduce investment in technologies with limited prospect of value. However, it is unclear whether early modelling is sufficiently specific to identify innovations with low value. It may be that early modelling is more useful for directing data gathering to reduce decision uncertainty. Early modelling is of primary benefit to the manufacturer and may have both positive and negative consequences for reimbursement processes that should be considered.

PURPOSE: Although good evidence exists regarding the clinical effectiveness of mechanical thrombectomy for people with acute ischaemic stroke, cost-effectiveness should also be considered. The aim of this study was to systematically review the evidence of cost-effectiveness of emergency endovascular therapy using mechanical thrombectomy in the management of acute ischaemic stroke. METHODS: The search was carried out in PubMed, EMBASE, Cochrane Library, and a grey literature search. Studies were included if they compared the costs and consequences of mechanical thrombectomy added to usual medical care compared to usual care alone for people with acute ischaemic stroke in the anterior and/or posterior region. Study quality was assessed using two appraisal tools tailored to economic evaluations. FINDINGS: Thirteen studies were identified including twelve cost-utility analyses and one cost-benefit analysis. Studies could be dichotomised into those that evaluated first-generation (n = 4) and second-generation (n = 9) mechanical thrombectomy devices. Six studies had low applicability, six had moderate applicability, and one had high applicability to other settings. All cost-utility studies reported incremental cost-effectiveness ratios that would be considered cost-effective under typical willingness-to-pay thresholds. CONCLUSIONS: If the outcomes of the trials underpinning the evidence of clinical effectiveness can be replicated, then mechanical thrombectomy is likely to be cost-effective by typical willingness-to-pay thresholds. This finding holds under the assumption that no investment is required to develop stroke centres to the standard required to provide a safe emergency endovascular service and that additional expenditure on timely patient transport is not required.

Relatively little analysis has taken place internationally on the consumer-reported benefits and costs to switching insurer in multi-payer health insurance markets. Ideally, consumers should be willing to switch out of consideration for price and quality and switching should be able to take place without incurring significant switching costs. Costs to switching come in many forms and understanding the nature of these costs is necessary if policy interventions to improve market competition are to be successful. This study utilises data from consumer surveys of the Irish health insurance market collected between 2009 and 2013 (N [Formula: see text] 1703) to examine consumer-reported benefits and costs to switching insurer. Probit regression models are specified to examine the relationship between consumer characteristics and reported switching costs, and switching behaviour, respectively. Overall evidence suggests that switchers in the Irish market mainly did so out of consideration for price. Transaction cost was the most common switching cost identified, reported by just under 1 in 7 non-switchers. Psychological switching costs may also be impacting behaviour. Moreover, high-risk individuals were more likely to experience switching costs and this was reflected in actual switching behaviour. A recent information campaign launched by the market regulator may prove beneficial in reducing perceived transaction costs in the market, however, a more focused campaign aimed at high-risk consumers may be necessary to reduce inequalities. Policy-makers should also consider the impact insurer behaviour may have on decision-making.

BACKGROUND: Internationally, the majority of out-of-hospital cardiac arrests where resuscitation is attempted (OHCAs) occur in private residential locations i.e. at home. The prospect of survival for this patient group is universally dismal. Understanding of the area-level factors that affect the incidence of OHCA at home may help national health planners when implementing community resuscitation training and services. METHODS: We performed spatial smoothing using Bayesian conditional autoregression on case data from the Irish OHCA register. We further corrected for correlated findings using area level variables extracted and constructed for national census data. RESULTS: We found that increasing deprivation was associated with increased case incidence. The methodology used also enabled us to identify specific areas with higher than expected case incidence. CONCLUSIONS: Our study demonstrates novel use of Bayesian conditional autoregression in quantifying area level risk of a health event with high mortality across an entire country with a diverse settlement pattern. It adds to the evidence that the likelihood of OHCA resuscitation events is associated with greater deprivation and suggests that area deprivation should be considered when planning resuscitation services. Finally, our study demonstrates the utility of Bayesian conditional autoregression as a methodological approach that could be applied in any country using registry data and area level census data.

BACKGROUND: In Western Europe, currently only Ireland and Portugal continue to provide universal neonatal bacillus Calmette-Guérin (BCG) vaccination programs, despite not being considered as high tuberculosis (TB) incidence countries. Other European countries only vaccinate infants considered at high risk of contracting TB. We evaluated the cost-effectiveness of selective BCG vaccination compared with strategies of universal and no vaccination. METHODS: An economic model was used to simulate a cohort from birth to life expectancy, taking the perspective of the publicly funded healthcare system. BCG protection was modeled to last 15 years. International vaccine efficacy data were combined with Irish epidemiologic and cost data. The model took into account long-term sequelae associated with TB meningitis and severe adverse reactions relating to the BCG vaccine. A fully probabilistic model was used to incorporate uncertainty across all parameters. RESULTS: At &OV0556;139,557 per quality-adjusted life year, selective vaccination was not cost-effective relative to a program of no vaccination. The incremental cost-effectiveness of universal vaccination was &OV0556;2.55 million per quality-adjusted life year relative to selective vaccination. There was substantial uncertainty regarding the effectiveness of BCG vaccination. The cost-effectiveness of selective vaccination could be substantially improved by reducing the cost of administering the vaccine. CONCLUSIONS: In the absence of changes to other aspects of TB control, a switch to selective vaccination will result in increased cases of childhood TB. Although not considered cost-effective, selective vaccination may be preferable to no vaccination until other changes to TB control may be implemented to reduce the risk of TB in children.

OBJECTIVES: The aim of this study was to illustrate the contribution of stakeholder engagement to the impact of health technology assessment (HTA) using an Irish HTA of a national public access defibrillation (PAD) program. BACKGROUND: In response to draft legislation that proposed a PAD program, the Minister for Health requested that Health Information and Quality Authority undertake an HTA to inform the design and implementation of a national PAD program and the necessary underpinning legislation. The draft legislation outlined a program requiring widespread installation and maintenance of automatic external defibrillators in specified premises. METHODS: Stakeholder engagement to optimize the impact of the HTA included one-to-one interviews with politicians, engagement with an Expert Advisory Group, public and targeted consultation, and positive media management. RESULTS: The HTA quantified the clinical benefits of the proposed PAD program as modest, identified that substantial costs would fall on small/medium businesses at a time of economic recession, and that none of the programs modeled were cost-effective. The Senator who proposed the Bill actively publicized the HTA process and its findings and encouraged participation in the public consultation. Participation of key stakeholders was important for the quality and acceptability of the HTA findings and advice. Media management promoted public engagement and understanding. The Bill did not progress. CONCLUSIONS: The HTA informed the decision not to progress with legislation for a national PAD program. Engagement was tailored to ensure that key stakeholders including politicians and the public were informed of the HTA process, the findings, and the advice, thereby maximizing acceptance. Appropriate stakeholder engagement optimizes the impact of HTA.

A review of the Health Information and Quality Authority's (HIQA) assessment of breast cancer surveillance cancer criticized how the results were presented and interpreted. The health technology assessment (HTA) investigated surveillance options for women aged less than 50 years who were at elevated risk of breast cancer. Surveillance strategies using digital mammography, magnetic resonance imaging, or a combination of the two modalities were modeled on the basis of diagnostic test accuracy. The HTA faced a number of issues, including the use of diagnostic test accuracy as a surrogate for long-term outcomes; modeling interventions that were not considered acceptable to clinicians; and extrapolating for screening intervals and age ranges not directly supported by available evidence. The evaluation of screening programs gives rise to challenges in terms of balancing an adequate exploration of the possible options while also being cognizant of what is appropriately supported by evidence. In this article, the authors of the HIQA report discuss the challenges posed by this particular HTA.

OBJECTIVES: To evaluate the cost-effectiveness of a national atrial fibrillation screening program in Ireland involving annual opportunistic pulse palpation of all those older than 65 years during general practitioner consultations, with an electrocardiogram being performed if an irregular pulse is detected. METHODS: A probabilistic Markov model was used to simulate costs and clinical outcomes in a hypothetical cohort of men and women with and without screening over the course of 25 years, using a societal perspective. RESULTS: Screening was associated with an incremental cost-effectiveness ratio of 23,004/quality-adjusted life-year compared with routine care. Nevertheless, if the relative risk of stroke and systematic embolism in screen-detected patients is more than 12% lower than that in patients with atrial fibrillation identified through routine practice, then screening would not be considered cost-effective at a willingness-to-pay threshold of 45,000/quality-adjusted life-year. An analysis comparing alternative combinations of start age and screening interval found that less frequent screening with a later start age may be more cost-effective than an annual screening from age 65 years. CONCLUSIONS: Annual opportunistic screening of men and women aged 65 years and older in primary care in Ireland is likely to be cost-effective using conventional willingness-to-pay thresholds, assuming that those detected through screening have a comparable stroke risk profile as those detected through routine practice. Raising the start age of screening or increasing the screening interval may improve the cost-effectiveness of a prospective screening program.

BACKGROUND: The determinants of consumer mobility in voluntary health insurance markets providing duplicate cover are not well understood. Consumer mobility can have important implications for competition. Consumers should be price-responsive and be willing to switch insurer in search of the best-value products. Moreover, although theory suggests low-risk consumers are more likely to switch insurer, this process should not be driven by insurers looking to attract low risks. METHODS: This study utilizes data on 320,830 VHI healthcare policies due for renewal between August 2013 and June 2014. At the time of renewal, policyholders were categorized as either 'switchers' or 'stayers', and policy information was collected for the prior 12 months. Differences between these groups were assessed by means of logistic regression. The ability of Ireland's risk equalization scheme to account for the relative attractiveness of switchers was also examined. RESULTS: Policyholders were price sensitive (OR 1.052, p < 0.01), however, price-sensitivity declined with age. Age (OR 0.971; p < 0.01) and hospital utilization (OR 0.977; p < 0.01) were both negatively associated with switching. In line with these findings, switchers were less costly than stayers for the 12 months prior to the switch/renew decision for single person (difference in average cost = 540.64) and multiple-person policies (difference in average cost = 450.74). Some cost differences remain for single-person policies following risk equalization (difference in average cost = 88.12). CONCLUSIONS: Consumers appear price-responsive, which is important for competition provided it is based on correct incentives. Risk equalization payments largely eliminated the profitable status of switchers, although further refinements may be required.

Scan statistics have been used extensively to identify temporal clusters of health events. We describe the temporal cluster detection methodology adopted by the EUROCAT (European Surveillance of Congenital Anomalies) monitoring system. Since 2001, EUROCAT has implemented variable window width scan statistic for detecting unusual temporal aggregations of congenital anomaly cases. The scan windows are based on numbers of cases rather than being defined by time. The methodology is imbedded in the EUROCAT Central Database for annual application to centrally held registry data. The methodology was incrementally adapted to improve the utility and to address statistical issues. Simulation exercises were used to determine the power of the methodology to identify periods of raised risk (of 1-18 months). In order to operationalize the scan methodology, a number of adaptations were needed, including: estimating date of conception as unit of time; deciding the maximum length (in time) and recency of clusters of interest; reporting of multiple and overlapping significant clusters; replacing the Monte Carlo simulation with a lookup table to reduce computation time; and placing a threshold on underlying population change and estimating the false positive rate by simulation. Exploration of power found that raised risk periods lasting 1 month are unlikely to be detected except when the relative risk and case counts are high. The variable window width scan statistic is a useful tool for the surveillance of congenital anomalies. Numerous adaptations have improved the utility of the original methodology in the context of temporal cluster detection in congenital anomalies.

AIM: Proposed Irish legislation aimed at increasing survival from out-of-hospital-cardiac-arrest (OHCA) mandates the provision of automated external defibrillators (AEDs) in a comprehensive range of publicly accessible premises in urban and rural areas. This study estimated the clinical and cost effectiveness of the legislation, compared with alternative programme configurations involving more targeted AED placement. METHODS: We used a cost-utility analysis to estimate the costs and consequences of public access defibrillation (PAD) programmes from a societal perspective, based on AED deployment by building type. Comparator programmes ranged from those that only included building types with the highest incidence of OHCA, to the comprehensive programme outline in the proposed legislation. Data on OHCA incidence and outcomes were obtained from the Irish Out-of-Hospital-Cardiac-Arrest Register (OHCAR). Costs were obtained from the Irish health service, device suppliers and training providers. RESULTS: The incremental cost effectiveness ratio (ICER) for the most comprehensive PAD scheme was 928,450/QALY. The ICER for the most scaled-back programme involving AED placement in transport stations, medical practices, entertainment venues, schools (excluding primary) and fitness facilities was 95,640/QALY. A 40% increase in AED utilisation when OHCAs occur in a public area could potentially render this programme cost effective. CONCLUSION: National PAD programmes involving widespread deployment of static AEDs are unlikely to be cost-effective. To improve cost-effectiveness any prospective programmes should target locations with the highest incidence of OHCA and be supported by efforts to increase AED utilisation, such as improving public awareness, increasing CPR and AED training, and establishing an EMS-linked AED register.
