Estimating the Theoretical Cost Implications of Funding New Drugs Considered Not to Be Cost-Effective.

This study aims to estimate the theoretical excess expenditure that would be incurred by the Irish state-payer, should drugs be reimbursed at their original asking ("list") price rather than at a price at which the drug is considered cost-effective. In Ireland, all new drugs are evaluated by the National Centre for Pharmacoeconomics. For this study, drugs that were submitted by pharmaceutical companies from 2012 to 2017 and considered not cost-effective at list price were reviewed. A total of 43 such drugs met our inclusion criteria, and their pharmacoeconomic evaluations were further assessed. The price at which the drug could be considered cost-effective (cost-effective price) at the upper cost-effectiveness threshold used in Ireland (€ 45 000/quality adjusted life-year) was estimated for 18 drugs with an available cost-effectiveness model. Then, for each drug, the list price and cost-effective price (both per unit) were both individually applied to 1 year of national real-world drug utilization data. This allowed the estimation of the expected expenditures under the assumptions of list price paid and cost-effective price paid. The resulting theoretical excess expenditure, the expenditure at list price minus the expenditure at the cost-effective price, was estimated to be €108.2 million. This estimate is theoretical because of the confidentiality of actual drug prices. The estimation is calculated using the list price and likely overestimates the actual excess expenditure, which would reduce to zero if cost-effective prices are agreed. Nevertheless, this estimate illustrates the importance of a process to assess the value of new drugs so that potential excess drug expenditure is identified.

Coronavirus Disease 2019: Considerations for Health Technology Assessment From the National Centre for Pharmacoeconomics Review Group.

It is expected that the coronavirus disease 2019 (COVID-19) pandemic will leave large deficits in the budgets of many jurisdictions. Funding for other treatments, in particular new treatments, may become more constrained than previously expected. Therefore, a robust health technology assessment (HTA) system is vital. Many clinical trials carried out during the pandemic may have been temporarily halted, while others may have had to change their protocols. Even trials that continue as normal may experience external changes as other aspects of the healthcare service may not be available to the patients in the trial, or the patients themselves may contract COVID-19. Consequently, many limitations are likely to arise in the provision of robust HTAs, which could have profound consequences on the availability of new treatments. Therefore, the National Centre for Pharmacoeconomics Review Group wishes to discuss these issues and make recommendations for applicants submitting to HTA agencies, in ample time for these HTAs to be prepared and assessed. We discuss how the pandemic may affect the estimation of the treatment effect, costs, life-years, utilities, discontinuation rates, and methods of evidence synthesis and extrapolation. In particular, we note that trials conducted during the pandemic will be subject to a higher degree of uncertainty than before. It is vital that applicants clearly identify any parameters that may be affected by the pandemic. These parameters will require considerably more scenario and sensitivity analyses to account for this increase in uncertainty.

Acute herpes zoster and post herpetic neuralgia in primary care: a study of diagnosis, treatment and cost.

Acute herpes zoster and its complication post herpetic neuralgia represent a significant challenge to primary care physicians in their care of an ageing population of patients. This was a cross-sectional observational study by means of a quantitative survey of 1,000 general practitioners registered in Ireland exploring the frequency of diagnosis, methods of treatment and cost of AHZ and PHN in primary care. We recorded an 18% response rate (n = 184) with an 83% completion rate (n = 152/184). 80% of cases of AHZ occurred in patients aged 50 years or more with 81% of study participants encountering cases at a rate of 1-3 patients per month. Famciclovir (37%) and valaciclovir (36%) were the most commonly prescribed antiviral agents. Mild opioids (32%) were the most common analgesic agents used for first line AHZ pain, and pregabalin (37%) the most commonly prescribed analgesic agent for second line AHZ pain. Pregabalin was also the most commonly prescribed analgesic for both first and second line PHN pain (29% and 24%, respectively). The mean per-case direct cost (medication and GP visits) of treating AHZ and PHN in primary care was €195 (range €153-€236) and €201 (range €140-€313), respectively. Based on national sentinel data the estimated annual direct costs of treating AHZ and PHN in primary care is €2,278,196 (range €1,793,399-€2, 763,445). The treatment of AHZ and PHN represents both a significant care and cost burden on primary care resources in Ireland in keeping with other European based studies.

Initial therapy, persistence and regimen change in a cohort of newly treated type 2 diabetes patients.

AIMS: The aim was to describe the utilization of antidiabetic agents, in terms of persistence and regimen change, in the management of a cohort of newly treated type 2 diabetes patients and to investigate associated socio-demographic and treatment factors. METHODS: A population-based retrospective cohort study was conducted using the national pharmacy claims database in Ireland. Subjects were analyzed for persistence and regimen change. Cox proportional hazards regression examined associations of socio-demographic and treatment factors on treatment patterns. Hazard ratios (HR) and 95% CIs are presented. RESULTS: A total of 20947 subjects were identified in the study over a 2 year period. Most were initiated on metformin (76%) or sulphonylureas (22%) and 77% were persistent with therapy 12 months after initiation. The likelihood of non-persistence was significantly lower in the youngest (40-49 years) age groups (reference 60-69 years) (HR 1.62, 95% CI 1.42, 1.84) and those on sulphonylureas (HR 1.49, 95% CI 1.36, 1.64). The likelihood of receiving a regimen change was significantly lower in the older (80+ years) age groups (HR 0.63, 95% CI 0.56, 0.71), females (HR 0.91, 95% CI 0.86, 0.95), and those with pre-existing CVD (1 vs. 0 CVD medicines) (HR 0.82, 95% CI 0.74, 0.90), and higher in those on sulphonylureas (HR 1.83, 95% CI 1.73, 1.94). CONCLUSIONS: Type of treatment, pre-existing CVD and demographic factors are shown to be associated with the observed treatment patterns. Guideline recommended agents were widely used on treatment initiation though a substantial minority were not initiated on the recommended first line agent. Use of guideline recommended agents was not as evident during treatment progression. Further optimization of initial and subsequent antidiabetic agent prescribing may be possible.

Using resource modelling to inform decision making and service planning: the case of colorectal cancer screening in Ireland.

BACKGROUND: Organised colorectal cancer screening is likely to be cost-effective, but cost-effectiveness results alone may not help policy makers to make decisions about programme feasibility or service providers to plan programme delivery. For these purposes, estimates of the impact on the health services of actually introducing screening in the target population would be helpful. However, these types of analyses are rarely reported. As an illustration of such an approach, we estimated annual health service resource requirements and health outcomes over the first decade of a population-based colorectal cancer screening programme in Ireland. METHODS: A Markov state-transition model of colorectal neoplasia natural history was used. Three core screening scenarios were considered: (a) flexible sigmoidoscopy (FSIG) once at age 60, (b) biennial guaiac-based faecal occult blood tests (gFOBT) at 55-74 years, and (c) biennial faecal immunochemical tests (FIT) at 55-74 years. Three alternative FIT roll-out scenarios were also investigated relating to age-restricted screening (55-64 years) and staggered age-based roll-out across the 55-74 age group. Parameter estimates were derived from literature review, existing screening programmes, and expert opinion. Results were expressed in relation to the 2008 population (4.4 million people, of whom 700,800 were aged 55-74). RESULTS: FIT-based screening would deliver the greatest health benefits, averting 164 colorectal cancer cases and 272 deaths in year 10 of the programme. Capacity would be required for 11,095-14,820 diagnostic and surveillance colonoscopies annually, compared to 381-1,053 with FSIG-based, and 967-1,300 with gFOBT-based, screening. With FIT, in year 10, these colonoscopies would result in 62 hospital admissions for abdominal bleeding, 27 bowel perforations and one death. Resource requirements for pathology, diagnostic radiology, radiotherapy and colorectal resection were highest for FIT. Estimates depended on screening uptake. Alternative FIT roll-out scenarios had lower resource requirements. CONCLUSIONS: While FIT-based screening would quite quickly generate attractive health outcomes, it has heavy resource requirements. These could impact on the feasibility of a programme based on this screening modality. Staggered age-based roll-out would allow time to increase endoscopy capacity to meet programme requirements. Resource modelling of this type complements conventional cost-effectiveness analyses and can help inform policy making and service planning.

Proton pump inhibitors: potential cost reductions by applying prescribing guidelines.

BACKGROUND: There are concerns that proton pump inhibitors (PPI) are being over prescribed in both primary and secondary care. This study aims to establish potential cost savings in a community drug scheme for a one year period according to published clinical and cost-effective guidelines for PPI prescribing. METHODS: Retrospective population-based cohort study in the Republic of Ireland using the Health Services Executive (HSE) Primary Care Reimbursement Services (PCRS) pharmacy claims database. The HSE-PCRS scheme is means tested and provides free health care including medications to approximately 30% of the Irish population. Prescription items are WHO ATC coded and details of every drug dispensed and claimants' demographic data are available. Potential cost savings (net ingredient cost) were estimated according to UK NICE clinical guidelines for all HSE-PCRS claimants on PPI therapy for ≥3 consecutive months starting in 2007 with a one year follow up (n=167,747). Five scenarios were evaluated; (i) change to PPI initiation (cheapest brand); and after 3 months (ii) therapeutic switching (cheaper brand/generic equivalent); (iii) dose reduction (maintenance therapy); (iv) therapeutic switching and dose reduction and (v) therapeutic substitution (H2 antagonist). RESULTS: Total net ingredient cost was €88,153,174 for claimants on PPI therapy during 2007. The estimated costing savings for each of the five scenarios in a one year period were: (i) €36,943,348 (42% reduction); (ii) €29,568,475 (34%); (iii) €21,289,322 (24%); (iv) €40,505,013 (46%); (v) €34,991,569 (40%). CONCLUSION: There are opportunities for substantial cost savings in relation to PPI prescribing if implementation of clinical guidelines in terms of generic substitution and step-down therapy is implemented on a national basis.

The Utility of a Rapid Review Evaluation Process to a National HTA Agency.

BACKGROUND AND OBJECTIVE: In Ireland, similar to other jurisdictions, health technology assessment (HTA) is used to inform the health payer's drug reimbursement decisions. These HTAs are conducted by the National Centre for Pharmacoeconomics (NCPE). In 2009, the NCPE introduced the Rapid Review process to identify drugs that do not require further assessment in the form of the previously established full HTA process. METHODS: A retrospective analysis of all Rapid Reviews submitted to the NCPE from 2010 to 2019, inclusive, was conducted. Rapid Review recommendation was recorded (i.e. full HTA required or not required). For those submitted from 2012 to 2019, additional data relating to the drug, economic and clinical evidence-related factors were collected. Multivariable logistic regression methods were used to model the relationship between these factors and the likelihood of requiring a full HTA. An exploratory analysis estimated the additional NCPE appraisal time that would have been required to evaluate all drugs, had the Rapid Review process not been established. RESULTS: Of the 446 Rapid Reviews submitted, approximately half (49.6%) were deemed to require a full HTA. Drugs for cancer indications, drugs designated first-in-class status, and high-cost drugs were positively and significantly associated with the likelihood of requiring a full HTA. No significant association was found for drugs for orphan indications when factors relating to cost and clinical evidence were included in the model. Without the Rapid Review process, an estimated additional 15,631 NCPE appraisal days would have been required to evaluate all drugs submitted over the 10-year period. CONCLUSIONS: This is the first study to use data uniquely available to the NCPE to evaluate factors associated with the requirement for a full HTA following a Rapid Review. The process has reduced the NCPE appraisal time required to evaluate all submissions over the study period. The NCPE's Rapid Review process allows for appropriate resource prioritisation within a national HTA agency.

A retrospective analysis of budget impact models submitted to the National Centre for Pharmacoeconomics in Ireland.

BACKGROUND: The National Centre for Pharmacoeconomics (NCPE) is a National HTA Agency in Ireland responsible for assessment of comparative clinical effectiveness, cost-effectiveness and potential budget impact of drugs on behalf of the Health Service Executive. This research aims to assess if the budget impact models submitted to the NCPE have accurate predicted utilisation, assess if the models are consistent in the parameters included, and determine if probabilistic sensitivity analyses would aid the characterization of uncertainty. METHODS: A retrospective analysis of budget impact models that had been submitted (January 2010-December 2017 inclusive) to the NCPE was performed. The input parameters in the budget impact model were recorded. For each drug, annual realised utilisation was compared with what had been predicted by the respective budget impact model. A probabilistic sensitivity analysis was also performed on each model. RESULTS: A total of 12 models were included; each model pertained to one drug for one indication. Of the 12 models, six underpredicted and six overpredicted the annual realised utilisation. There were a range of different parameters included in each of the budget impact models. A probabilistic sensitivity analysis did not improve the characterization of uncertainty. CONCLUSION: This research has demonstrated that budget impact models submitted to a national HTA agency have limited accuracy in predicting realised utilisation, and there is inconsistency among the parameters included. An electronic budget impact template for applicants has been developed, as a more systematic approach, for their submissions to the NCPE.

Health Technology Assessment of Drugs in Ireland: An Analysis of Timelines.

BACKGROUND: The National Centre for Pharmacoeconomics (NCPE) is commissioned by the Corporate Pharmaceutical Unit of the Health Service Executive (HSE-CPU) to assess the evidence for the comparative effectiveness and cost effectiveness of drugs for use by patients in Ireland. All new drugs are required to undergo rapid review (RR) appraisal by the NCPE. Following this, high-cost drugs or those predicted to have a significant budget impact then undergo a full health technology assessment (HTA) appraisal by the NCPE. OBJECTIVE: The objective of this paper was to quantify each stage of the timeline from marketing authorisation (MA) to completion of HTA appraisal and explore the association between submission features and the time to appraise RRs and HTAs. METHODS: All RRs and HTAs submitted to the NCPE (2015-2017 inclusive) were included in the dataset. Several dates and features of each submission were also listed for the purpose of analysis. RESULTS: A total of 158 RR and 49 HTA appraisals were completed by the NCPE between 2015 and 2017. The median time from MA to submission of RR was 59 days; the median time to appraise RR was 31.5 days. Only 49% of RRs appraised (2015-2017 inclusive) were recommended for HTA. The median time from RR decision to submission of HTA was 115 days, and the median time taken by the NCPE to appraise an HTA was 131 days. CONCLUSION: This paper identifies which stages of the process make a substantial contribution to the HTA timeline. Time to submission of RR varied widely between submissions, with only a few companies choosing to submit prior to an MA being granted. The average RR appraisal time was in line with the 4-week timeframe set out in a 2016 agreement. The time to appraise an HTA was longer than the 90-day timeframe.

Cost-effectiveness of treatments reducing coronary heart disease mortality in Ireland, 2000 to 2010.

OBJECTIVE: Coronary heart disease (CHD) is associated with a large burden of disease in Ireland and is responsible for more than 6000 deaths annually. This study examined the cost-effectiveness of specific CHD treatments in Ireland. METHODS: Irish epidemiological data on patient numbers and median survival in specific groups, plus the uptake, effectiveness, and costs of specific interventions, all stratified by age and sex, were incorporated into a previously validated CHD mortality model, the IMPACT model. This model calculates the number of life-years gained (LYGs) by specific cardiology interventions to generate incremental cost-effectiveness ratios (ICERs) per LYG for each intervention. RESULTS: In 2000, medical and surgical treatments together prevented or postponed approximately 1885 CHD deaths in patients aged 25 to 84 years, and thus generated approximately 14,505 extra life-years (minimum 7270, maximum 22,475). In general, all the cardiac interventions investigated were highly cost-effective in the Irish setting. Aspirin, beta-blockers, ACE inhibitors, spironolactone, and warfarin for specific conditions were the most cost-effective interventions (< euro 3000/LYG), followed by the statins for secondary prevention (< euro 6500/LYG). Revascularization for chronic angina and primary angioplasty for myocardial infarction, although still cost-effective, had the highest ICER (between euro 12,000 and euro 20,000/LYG). CONCLUSIONS: Using a comprehensive standardized methodology, cost-effectiveness ratios in this study clearly favored simple medical treatments for myocardial infarction, secondary prevention, angina, and heart failure.

Estimating drug costs in economic evaluations in Ireland and the UK: an analysis of practice and research recommendations.

Cost estimates for the drug of interest, its comparator and concomitant drugs are an important component of pharmacoeconomic evaluations. However, whilst in general considerable efforts are made by analysts to ensure valid and accurate parameter inputs, the methods for estimating drug costs are often lacking. We reviewed recent pharmacoeconomic evaluations undertaken in Ireland and the UK and documented the sources of data for drug costs and the methods of cost estimation. Methods were often inadequately described and, where adequate information was available, there was considerable variation and limitations in the methods used, thereby reducing the comparability of studies. Data from a sample of studies from other Northern European countries suggested that the findings from Ireland and the UK were not atypical. In order to improve current practice we suggest a methodological checklist for use in future studies.

A cost-effectiveness model comparing rivaroxaban and dabigatran etexilate with enoxaparin sodium as thromboprophylaxis after total hip and total knee replacement in the irish healthcare setting.

BACKGROUND: It has been estimated that major orthopaedic surgery has the highest risk of venous thromboembolism (deep vein thrombosis and pulmonary embolism) when compared with other surgery. Two new orally active anticoagulants have recently become licensed in Ireland for the primary prevention of venous thromboembolism in adult patients undergoing elective total hip replacement (THR) or total knee replacement (TKR). Rivaroxaban (Xarelto) is a direct factor Xa inhibitor and dabigatran etexilate (Pradaxa) is a prodrug of the active compound dabigatran, which inhibits thrombin. OBJECTIVE: To evaluate the cost effectiveness of rivaroxaban and dabigatran etexilate compared with enoxaparin sodium for the prophylaxis of venous thromboembolism in patients undergoing elective THR and TKR in the Irish healthcare setting. METHODS: The evaluation was conducted from the Irish health-payer perspective. A static decision-tree model was developed with a 180-day post-surgery time horizon. Separate models for the disease states THR and TKR were run to accommodate the different venous thromboembolism risks associated with each procedure. Outcome measures were QALYs and life-years gained (LYG). Costs were valued in euro, year 2008 values. One-way sensitivity analysis of all probabilities in the model was performed. A probabilistic sensitivity analysis using second-order Monte Carlo simulation was performed to determine the probability of cost effectiveness at euro 45,000 per QALY threshold. RESULTS: In the THR base-case model, rivaroxaban dominated both dabigatran etexilate and enoxaparin sodium. The incremental cost-effectiveness ratios for dabigatran etexilate relative to enoxaparin were euro 23,934 per LYG and euro 17,835 per QALY. In the TKR base-case model, rivaroxaban dominated both dabigatran etexilate and enoxaparin sodium. Dabigatran etexilate also dominated enoxaparin sodium. In the one-way sensitivity analysis, the THR model was robust to all but four probability variations; the TKR model was robust to all variations. At a cost-effectiveness threshold of euro 45,000 per QALY, the probability that rivaroxaban was the most cost-effective strategy after THR was 39%, followed by dabigatran etexilate at 32% and enoxaparin sodium at 29%. The probability that rivaroxaban was the most cost-effective strategy after TKR was 46%, followed by dabigatran etexilate at 30% and enoxaparin sodium at 24%. CONCLUSION: Base-case analysis indicates that when both rivaroxaban and dabigatran etexilate are compared with enoxaparin sodium, rivaroxaban is the less costly and more effective option after THR and TKR. Probabilistic sensitivity analysis indicates that rivaroxaban is the most cost-effective strategy at a cost-effectiveness threshold of euro 45,000 per QALY; however, there is uncertainty regarding this strategy being more cost effective than dabigatran etexilate when both are compared with enoxaparin sodium.

Analysis of Health Technology Assessments of Orphan Drugs in Ireland from 2012 to 2017.

BACKGROUND: In Ireland, health technology assessment (HTA) submissions for orphan drugs or drugs for rare diseases have increased in recent years but have not been explicitly analysed. All evaluations are conducted by the National Centre for Pharmacoeconomics (NCPE). OBJECTIVES: The objectives of this study were to ascertain the number of orphan drug submissions to the NCPE and determine how these drugs proceeded through the NCPE critical evaluation process compared with non-orphan drug submissions. METHODS: This was a retrospective analysis of applicant rapid review submissions made to the NCPE from January 2012 to December 2017 inclusive. Drugs were categorised according to the following definitions: orphan (non-cancer) drug, orphan (cancer) drug and ultra-orphan drug. In each of the three categories, the outcome of rapid review appraisal, and where relevant, the outcome of the subsequent HTA was recorded. RESULTS: During the period of study, 280 rapid review submissions were made to the NCPE, of which 21 were for orphan (non-cancer) drugs, 24 were for orphan (cancer) and ten were for ultra-orphan drugs. After rapid review, 44%, 78% and 100% of orphan (non-cancer) drugs, orphan (cancer) drugs and ultra-orphan products, respectively, were recommended for full HTA. When the outcome of the rapid review process was compared between orphan drugs and non-orphan drugs, a statistically significant difference was detected in the proportion of rapid reviews for which the outcome was 'HTA recommended' (Pearson's Chi-squared test; p = 0.04). CONCLUSIONS: The number of submissions to the NCPE for orphan drugs has increased in recent years. The rapid review and HTA process in Ireland plays a role in supporting the reimbursement decision-making process for orphan drugs in a similar manner to the process established for non-orphan drugs. However, the outcome of the reimbursement process for orphan drugs versus non-orphan drugs (in terms of access for patients) has yet to be quantified.

Economic evaluation of a universal childhood pneumococcal conjugate vaccination strategy in Ireland.

OBJECTIVE: To evaluate the cost-effectiveness of implementing a universal infant 7-valent pneumococcal conjugate vaccine (PCV7) vaccination program in the Irish health-care setting from the health-care payers' perspective. METHODS: A model was constructed in MS Excel to follow a cohort of vaccinated and unvaccinated individuals from birth over a 5-year period. The reduction in events that would be associated with PCV7 vaccination and the mortality and cost resulting from these events were analyzed. In a separate submodel, the effect of herd immunity was investigated. RESULTS: Implementing a PCV7 vaccine program in Ireland in a birth cohort of 61,000 infants would be expected to prevent 7703 cases of pneumococcal-related infections over 5 years, resulting in costs avoided of 2.05 million euros increasing to 4.6 million euros if the effect of herd immunity was included. The baseline incremental cost-effectiveness ratio was 249,591 euros/life years gained (LYG), which reduced to 5997 euros/LYG when the effect of herd immunity was included. CONCLUSIONS: A universal infant pneumococcal conjugate vaccination could be considered highly cost-effective in the Irish health-care setting from a health-care payers' perspective, if viewed in terms of the herd immunity effect. The results of this study have positive ramifications for countries in the early stages of health technology assessment.

Cost effectiveness of hepatitis B vaccination strategies in Ireland: an economic evaluation.

BACKGROUND: In accordance with World Health Organization recommendations, many European countries have introduced universal hepatitis B vaccination policies. The UK and Ireland are exceptions. In this study, we conducted an economic evaluation of a universal infant hepatitis B vaccination programme, using a six-component vaccine, compared with the current selective strategy of vaccinating high-risk infants with a monovalent hepatitis B vaccine. METHODS: A cost effectiveness analysis was conducted using a Markov model. The perspective of the analysis was the Irish Health Service Executive. Unit cost and resource utilization data were derived from expert clinical opinion, published sources, diagnosis-related group costs for hospital admissions and local cost estimates for medical fees and laboratory investigations. A full probabilistic sensitivity analysis was undertaken. Both costs and outcomes were modelled over a period of 80 years and discounted at 3.5%. RESULTS: Assuming an incidence of acute hepatitis B virus (HBV) infection in Ireland of 8.4 per 100,000 population, the incremental cost effectiveness ratio ranged from euro10,992/life years gained (LYG) to euro67 200/LYG, at the lowest and highest price estimates for the six-component vaccine, respectively. The cost effectiveness of universal versus selective hepatitis B vaccination was sensitive to the risk of acute HBV infection, the cost of the universal infant vaccination programme and the discount rate. CONCLUSION: At a cost of euro29.00 per dose of the six-component vaccine, universal infant hepatitis B vaccination is cost effective at euro37 018/LYG. This compares favourably with other preventive programmes in Ireland.

The potential impact of implementing a system of generic substitution on the community drug schemes in Ireland.

This study estimated the potential savings in Ireland in 2003 if a system of generic substitution were introduced, under the two main Community Drug Schemes (General Medical Services, GMS, and Drugs Payment, DP). The GMS and DP schemes accounted for 82% of state expenditure on the Community Drug Schemes in 2003. Twenty one per cent of prescription items on the GMS scheme and 23% of items on the DP scheme were dispensed as a proprietary preparation when a generic equivalent was available. Substitution of the cheapest generic equivalent preparations of the top 30 drugs by expenditure in each scheme would result in estimated annual savings of 12.7 million on the GMS and 9.1 million on the DP scheme. Potential savings if the most expensive generic drugs were dispensed would be in the region of 9.0 million on the GMS and 6.4 million on the DP scheme. Comparison of these results with a similar analysis of 2001 data illustrates the potential for an increase in savings over time.

Cost-effectiveness of natriuretic peptide-based screening and collaborative care: a report from the STOP-HF (St Vincent's Screening TO Prevent Heart Failure) study.

AIMS: Prevention of cardiovascular disease and heart failure (HF) in a cost-effective manner is a public health goal. This work aims to assess the cost-effectiveness of the St Vincent's Screening TO Prevent Heart Failure (STOP-HF) intervention. METHODS AND RESULTS: This is a substudy of 1054 participants with cardiovascular risk factors [median age 65.8 years, interquartile range (IQR) 57.8:72.4, with 4.3 years, IQR 3.4:5.2, follow-up]. Annual natriuretic peptide-based screening was performed, with collaborative cardiovascular care between specialist physicians and general practitioners provided to patients with BNP levels >50 pg/mL. Analysis of cost per case prevented and cost-effectiveness per quality-adjusted life year (QALY) gained was performed. The primary clinical endpoint of LV dysfunction (LVD) with or without HF was reduced in intervention patients [odds ratio (OR) 0.60; 95% confidence interval (CI) 0.38-0.94; P = 0.026]. There were 157 deaths and/or emergency hospitalizations for major adverse cardiac events (MACE) in the control group vs. 102 in the intervention group (OR 0.68; 95% CI 0.49-0.93; P = 0.01). The cost per case of LVD/HF prevented was €9683 (sensitivity range -€843 to €20 210), whereas the cost per MACE prevented was €3471 (sensitivity range -€302 to €7245). Cardiovascular hospitalization savings offset increased outpatient and primary care costs. The cost per QALY gain was €1104 and the intervention has an 88% probability of being cost-effective at a willingness to pay threshold of €30 000. CONCLUSION: Among patients with cardiovascular risk factors, natriuretic peptide-based screening and collaborative care reduced LVD, HF, and MACE, and has a high probability of being cost-effective. TRIAL REGISTRATION: NCT00921960.

Pricing and reimbursement of drugs in Ireland.

Expenditure on healthcare in Ireland, which is mainly derived from taxation, has increased considerably in recent years to an estimated 9.2 billion euro in 2003. Pharmaceuticals account for approximately 10% of total healthcare expenditure. Approximately one-third of patients receive their medications free of charge whilst the remaining two-thirds are subject to a co-payment threshold of 78 euro per month, i.e. 936 euro per year. The price of medications in Ireland is linked to those of five other member states where the price to the wholesaler of any medication will not exceed the lesser of the currency-adjusted wholesale price in the United Kingdom or the average of wholesale prices in Denmark, France, Germany, The Netherlands and the United Kingdom. A price freeze at the introduction price has been in existence since 1993. Despite the price freeze, expenditure on medicines on the community drugs scheme has increased from 201 million euro in 1993 to 898 million euro in 2002. The two main factors contributing to the increased expenditure on medicines include "product mix", the prescribing of new and more expensive medication, and "volume effect" comprising growth in the number of prescription items. Changing demographics and the extension of the General Medical Services (GMS) Scheme to provide free medicines for all those over the age of 70 years have also contributed. Prior to reimbursement under the community drugs schemes, a medicine must be included in the GMS code book or positive list. A demonstration of cost-effectiveness is not a pre-requisite for reimbursement.

The high cost of medicines in Ireland. Is it time to change the pricing mechanism?

This study compared the prices of prescription medicines in Ireland to those in other countries to determine potential cost savings on the largest community drug scheme if an alternative pricing mechanism were adopted. The analysis covered a sample of 39 drugs (44.8% of the total ingredient cost) selected from the top 70 drugs in order of total ingredient cost. Potential cost savings ranged from Euro 20.73 million if a Danish price were adopted, to Euro 16.23 million for the average European price, to Euro 6.82 million for the UK price. The estimated savings were statistically significant for the Danish and average European price but not for the UK price. This study demonstrates the high ex-wholesale price of prescription medications in Ireland.
