Poor adherence with osteoporosis medications results in around a 50% reduction in the potential benefits observed in clinical trials and a doubling of the cost per QALY gained from these medications. Depending on their costs and outcomes, programs to improve adherence have the potential to be an efficient use of resources.

Investigating the pharmacoeconomic impact of any diagnostic or therapeutic intervention in the Irish healthcare setting is currently compromised by the lack of detailed cost data. Consequently, we conducted a number of microcosting studies in the areas of acute myocardial infarction, cardiac failure and HIV, from the hospital perspective. The results of these microcosting studies were compared with the costing estimates assigned to hospital admissions, based on the diagnosis-related group system. Differences ranged from 9 to 66%. It was concluded that the diagnosis related group system is a useful estimate of costs for patient admissions in the absence of detailed cost of illness data. However, supplementary costing studies should be performed for certain therapeutic areas, particularly those where investigation and/or treatment costs are high.

To identify adherence and persistence levels with urate-lowering therapies using the national administrative pharmacy claim database. This was a retrospective, pharmacy claims-based analysis of dispensed anti-gout medications on the Irish national HSE-PCRS scheme database between January 2008 and December 2012. Adherence is defined by the medication possession ratio (MPR), and patients were considered to be adherent if the MPR ≥80 % (good adherers) in any given time period. Persistence was defined as continued use of therapy with no periods exceeding a refill gap of >63 days (9 weeks). Logistic regression analysis was used to predict odd ratios (OR) and 95 % confidence interval (CI) for persistence and adherence in relation to age, gender and level of comorbidity. There was a 53 % increase in the number of patients prescribed anti-gout medications between 2008 and 2012 with an increase of 27 % in the associated ingredient cost of these medications. Allopurinol accounted for 87 % of the prescribing and febuxostat accounted for a further 9 %. In patients who started on 100 mg allopurinol, only 14.6 % were titrated to the 300 mg dose. For all those initiating urate-lowering therapies, 45.8 % of patients were persistent with treatment at 6 months decreasing to 22.6 % at 12 months. In multivariate analysis, females had poorer adherence (OR = 0.83 (0.77-0.90)), and increasing age was associated with increased adherence (OR = 4.19 (2.53-6.15)) Increasing comorbidity score was associated with increased adherence and persistence at 6 months (OR = 0.68 (0.59-0.79)). Adherence with anti-gout medications in this study cohort was relatively low. Sustained treatment for gouty arthritis is essential in the prevention of serious adverse outcomes.Significance and Innovations-Poor adherence to medications prescribed to patients for the management of chronic diseases such as gout is an ongoing problem which urgently needs to be addressed.-Some of the reasons identified for poor adherence to anti-gout medications include the risk of flare of acute gout with the initiation of urate-lowering therapy (ULT), poor response to ULT and persistence of attacks of acute gout, suboptimal dosing of allopurinol therapy and intolerance of allopurinol.-The results of this study identified adherence and persistence rates of approximately 50 % at 6 months which is in line if not lower than many of the other published studies to date which have measured adherence and persistence using pharmacy claims databases.-The results of poor adherence and persistence affect both the health of the patients with financial implications for the healthcare service.

We found statistically significant differences in patients' preferences for anti-osteoporosis medications between countries, especially for the mode of administration. Our findings emphasized that international treatment recommendations should allow for local adaptation, and that understanding individual preferences is important if we want to improve the quality of clinical care for patients with osteoporosis.

This economic evaluation suggests that the addition of spironolactone to standard therapy for patients with severe chronic heart failure is not only safe and effective, but is highly cost-effective in the Irish healthcare setting.

There has been a significant increase in the number of fracture admissions in Irish men and women over the past 15 years. This is projected to increase further over the next three decades which will place a significant burden on the Irish healthcare system.

Background: Glaucoma affects approximately 2% of the population in developed countries and is estimated to affect 67 million people worldwide. The authors investigated the effect of the introduction of new medications on the volume and cost of drugs for glaucoma in two countries, Northern Ireland (NI, population approximately 1.7 million) and the Republic of Ireland (ROI, population approximately 3.9 million) in the 8 years from 1996 to 2003. They also looked at the surgical rates for glaucoma within the same time period for the two countries. Methods: A retrospective analysis was performed of drug costs, prescribing data, and operation rates for glaucoma in Ireland from January 1996 to December 2003. Information regarding costs and volume were obtained for each type of glaucoma drug and these were then grouped into the glaucoma treatment subsections as found in the British National Formulary. The drug information was obtained from the Central Services Agency in NI and IMS Health in the ROI and included both public and private prescriptions. The information on surgical rates for glaucoma was obtained from the Department of Health and Social Services in NI and the Hospital In-patient Enquiry (HIPE) data national files in the ROI. Results: There was a 30% increase in prescription items for glaucoma in NI and a 59% increase in the ROI from 1996 to 2003. The costs increased more rapidly than the number of items: 227% in the ROI and 78% in NI from January 1996 to December 2003. In the ROI, there was an average 19% year on year increase in costs. In NI, new drugs accounted for 40% of the quantity of prescription items for glaucoma and 63% of the market cost in 2003. In the ROI new drugs accounted for 57% of the quantity and 77% of the market cost for glaucoma in 2003; prostaglandin analogue drugs alone accounted for 53% of the cost. The number of trabeculectomies performed decreased by more than 60% in both countries. Conclusion: Volume and cost of glaucoma drugs increased dramatically in both NI and the ROI from 1996 to 2003, probably the result of a combination of changing demographics and a changing approach towards the management of patients with glaucoma and ocular hypertension. In 2003 in the ROI, prostaglandin analogues were the most commonly prescribed class of drug for patients with glaucoma and/or ocular hypertension causing a profound rise in drug expenditure.

Hospitalisations for osteoporotic-type fractures continued to increase in Ireland. Hip fractures increased by 7 % in women and 20 % in men.
