Biosimilar infliximab introduction into the gastro-enterology care pathway in a large acute Irish teaching hospital: a story behind the evidence
Background and aim: Biosimilar medicines are not considered exact replicas of originator biological medicines. As a result, prescribers can be hesitant to introduce such medicines into the clinical setting until evidence surfaces confirming their safety and effectiveness. In Ireland, a national biosimilar medicines policy is currently in development but the decision to prescribe biosimilar medicines remains at the discretion of the physician. The aim of this descriptive review is to tell the story of the evidence used by a large acute Irish teaching hospital to introduce biosimilar infliximab CT-P13 for the treatment of inflammatory bowel disease (IBD) in a safe and timely manner into routine care. Methods: To explore the evidence supporting the effective introduction of biosimilar infliximab in a large acute Irish teaching hospital, a literature review was conducted. Evidence consisted of published studies, reviews, reports, position statements, articles, clinical guidelines, and recommendations from national bodies, regulatory authorities and professional organizations. All evidence was published in English. Results and discussion: In September 2014, the accumulated evidence base provided physicians with reassurance to prescribe biosimilar infliximab CT-P13 for new patients suffering from IBD in this large acute Irish teaching hospital. In September 2016, as the evidence base grew, physicians began to safely and confidently switch patients from the originator infliximab product to the biosimilar product. Conclusion: There was a significant time lag between regulatory approval and clinical acceptance given that the European Medicines Agency had granted market authorization for biosimilar infliximab CT-P13 three years prior to the initiation of this hospital's switching process. Although conservative in their execution, the authors conclude that with the existential concern and uncertainty still surrounding biosimilar medicines, a distinct and individualized approach for biosimilar medicine implementation is required. It is with hope that the Irish biosimilar medicines policy will improve upon biosimilar medicine clinical acceptance once published
Expanding health technology assessment towards broader value: Ireland as a case study
Healthcare innovations often represent important improvements in population welfare, but at what cost, and to whom? Health technology assessment (HTA) is a multidisciplinary process to inform resource allocation. HTA is conventionally anchored on health maximization as the only relevant output of health services. If we accept the proposition that health technologies can generate value outside the healthcare system, resource allocation decisions could be suboptimal from a societal perspective. Incorporating broader value in HTA as derived from social values and patient experience could provide a richer evaluative space for informing resource allocation decisions. This article considers how HTA is practiced and what its current context implies for adopting broader value to evaluating health technologies. Methodological challenges are highlighted, as is a future research agenda. Ireland serves as an example of a healthcare system that both has an explicit role for HTA and is evolving under a current program of reform to offer universal, single-tier access to public services. There are various ways in which HTA processes could move beyond health, including considering the processes of care delivery and/or expanding the evaluative space to some broader concept of well-being. Methods to facilitate the latter exist, but their adaptation to HTA is still emerging. We recommend a multi-stakeholder working group to develop and advance an international agenda for HTA that captures welfare/benefit beyond health.Health Research Board
Out of pocket or out of control: A qualitative analysis of healthcare professional stakeholder involvement in pharmaceutical policy change in Ireland
Background: Mandatory co-payments attached to prescription medicines on the Irish public health insurance [General Medical Services (GMS)] scheme have undergone multiple iterations since their introduction in October 2010. To date, whilst patientsâ opinions on said co-payments have been evaluated, the perspectives of community pharmacists and general practitioners (GPs) have not. Objective: To explore the involvement and perceptions of community pharmacists and GPs on this pharmaceutical policy change. Methods: A qualitative study using purposive sampling alongside snowballing recruitment was used. Nineteen interviews were conducted in a Southern region of Ireland. Data were analysed using the Framework Approach. Results: Three major themes emerged: 1) the withered tax-collecting pharmacist; 2) concerns and prescribing patterns of physicians; and 3) the co-payment system â impact and sustainability. Both community pharmacists and GPs accepted the theoretical concept of a co-payment on the GMS scheme as it prevents moral hazard. However, there were multiple references to the burden that the current method of co-payment collection places on community pharmacists in terms of direct financial loss and reductions in workplace productivity. GPs independently suggested that a co-payment system may inhibit moral hazard by GMS patients in the utilisation of GP services. It was unclear to participants what evidence is guiding the GMS co-payment fee changes. Conclusion: Interviewees accepted the rationale for the co-payment system, but reform is warranted
Cost minimization analysis of intravenous or subcutaneous trastuzumab treatment in patients with HER2-positive breast cancer in Ireland
Background: Two large acute Irish University teaching hospitals changed the manner in which they treated human epidermal growth factor receptor (HER)2-positive breast cancer patients by implementing the administration of trastuzumab via the subcutaneous (SC) route into their clinical practice. The study objective is to compare the trastuzumab SC and trastuzuamb intravenous (IV) treatment pathways in both hospitals and assess which route is more cost-effective and time saving in relation to active health care professional (HCP) time. Materials and Methods: A prospective observational study in the form of cost minimization analysis constituted the study design. Active HCP time for trastuzumab SC- and IV-related tasks were recorded. Staff costs were calculated using fully loaded salary costs. Loss of productivity costs for patients were calculated using the human capital method. Results: On average, the total HCP time saved per trastuzumab SC treatment cycle relative to trastuzumab IV treatment cycle was 59.21 minutes. Time savings in favor of trastuzumab SC resulted from quicker drug reconstitution, no IV catheter installation/removal, and less HCP monitoring. Over a full treatment course of 17 cycles, average HCP time saved accumulates to 16.78 hours, with an estimated direct cost saving of Ăą ÂŹ1609.99. Loss of productivity for patients receiving trastuzumab IV (2.15 days) was greater than that of trastuzumab SC (0.60 days) for a full treatment course. Conclusion: Trastuzumab SC treatment has proven to be a more cost-effective option than trastuzumab IV treatment that generated greater HCP time savings in both study sites. Healthcare policymakers should consider replacing trastuzumab IV with trastuzumab SC treatment in all eligible patients
Integrating In Silico and In Vitro Analysis of Peptide Binding Affinity to HLA-Cw*0102: A Bioinformatic Approach to the Prediction of New Epitopes
Background: Predictive models of peptide-Major Histocompatibility Complex (MHC) binding affinity are important components of modern computational immunovaccinology. Here, we describe the development and deployment of a reliable peptide-binding prediction method for a previously poorly-characterized human MHC class I allele, HLA-Cw*0102.
Methodology/Findings: Using an in-house, flow cytometry-based MHC stabilization assay we generated novel peptide binding data, from which we derived a precise two-dimensional quantitative structure-activity relationship (2D-QSAR) binding model. This allowed us to explore the peptide specificity of HLA-Cw*0102 molecule in detail. We used this model to design peptides optimized for HLA-Cw*0102-binding. Experimental analysis showed these peptides to have high binding affinities for the HLA-Cw*0102 molecule. As a functional validation of our approach, we also predicted HLA-Cw*0102-binding peptides within the HIV-1 genome, identifying a set of potent binding peptides. The most affine of these binding
peptides was subsequently determined to be an epitope recognized in a subset of HLA-Cw*0102-positive individuals
chronically infected with HIV-1.
Conclusions/Significance: A functionally-validated in silico-in vitro approach to the reliable and efficient prediction of peptide binding to a previously uncharacterized human MHC allele HLA-Cw*0102 was developed. This technique is generally applicable to all T cell epitope identification problems in immunology and vaccinology
Cost-effectiveness analysis of a physician-implemented medication screening tool in older hospitalised patients in Ireland
Background: A recent randomised controlled trial conducted in an Irish University teaching hospital that evaluated a physician-implemented medication screening tool, demonstrated positive outcomes in terms of a reduction in incident adverse drug reactions. Objective: The present study objective was to evaluate the cost effectiveness of physicians applying this screening tool to older hospitalised patients compared with usual hospital care in the context of the earlier randomised controlled trial. Method: We used a cost-effectiveness analysis alongside a conventional outcome analysis in a cluster randomised controlled trial. Patients in the intervention arm (nâ=â360) received a multifactorial intervention consisting of medicines reconciliation, communication with patientsâ senior medical team, and generation of a pharmaceutical care plan in addition to usual medical and pharmaceutical care. Control arm patients (nâ=â372) received usual medical and pharmaceutical care only. Incremental cost effectiveness was examined in terms of costs to the healthcare system and an outcome measure of adverse drug reactions during inpatient hospital stay. Uncertainty in the analysis was explored using a cost-effectiveness acceptability curve. Results: On average, the intervention arm was more costly but was also more effective. Compared with usual care (control), the intervention was associated with a non-statistically significant increase of âŹ877 (95% confidence interval â âŹ1807, âŹ3561) in the mean healthcare cost, and a statistically significant decrease of â 0.164 (95% confidence interval â 0.257, â 0.070) in the mean number of adverse drug reaction events per patient. The associated incremental cost-effectiveness ratio per adverse drug reaction averted was âŹ5358. The probability of the intervention being cost effective at threshold values of âŹ0, âŹ5000 and âŹ10,000 was 0.236, 0.455 and 0.680, respectively. Conclusion: Based on the evidence presented, this physician-led intervention is not likely to be cost effective compared with usual hospital care. To inform future healthcare policy decisions in this field, more economic analyses of structured medication reviews by other healthcare professionals and by computerised clinical decision support software need to be conducted
Effect of remote ischaemic conditioning on clinical outcomes in patients with acute myocardial infarction (CONDI-2/ERIC-PPCI): a single-blind randomised controlled trial.
BACKGROUND: Remote ischaemic conditioning with transient ischaemia and reperfusion applied to the arm has been shown to reduce myocardial infarct size in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). We investigated whether remote ischaemic conditioning could reduce the incidence of cardiac death and hospitalisation for heart failure at 12 months. METHODS: We did an international investigator-initiated, prospective, single-blind, randomised controlled trial (CONDI-2/ERIC-PPCI) at 33 centres across the UK, Denmark, Spain, and Serbia. Patients (age >18 years) with suspected STEMI and who were eligible for PPCI were randomly allocated (1:1, stratified by centre with a permuted block method) to receive standard treatment (including a sham simulated remote ischaemic conditioning intervention at UK sites only) or remote ischaemic conditioning treatment (intermittent ischaemia and reperfusion applied to the arm through four cycles of 5-min inflation and 5-min deflation of an automated cuff device) before PPCI. Investigators responsible for data collection and outcome assessment were masked to treatment allocation. The primary combined endpoint was cardiac death or hospitalisation for heart failure at 12 months in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT02342522) and is completed. FINDINGS: Between Nov 6, 2013, and March 31, 2018, 5401 patients were randomly allocated to either the control group (n=2701) or the remote ischaemic conditioning group (n=2700). After exclusion of patients upon hospital arrival or loss to follow-up, 2569 patients in the control group and 2546 in the intervention group were included in the intention-to-treat analysis. At 12 months post-PPCI, the Kaplan-Meier-estimated frequencies of cardiac death or hospitalisation for heart failure (the primary endpoint) were 220 (8·6%) patients in the control group and 239 (9·4%) in the remote ischaemic conditioning group (hazard ratio 1·10 [95% CI 0·91-1·32], p=0·32 for intervention versus control). No important unexpected adverse events or side effects of remote ischaemic conditioning were observed. INTERPRETATION: Remote ischaemic conditioning does not improve clinical outcomes (cardiac death or hospitalisation for heart failure) at 12 months in patients with STEMI undergoing PPCI.

Health economics in the Irish healthcare setting
THESIS 8586Economic analysis plays a key role in deciding which healthcare interventions should be made available in collectively funded healthcare systems. The aim of this thesis is to examine the application of health economics in the Irish healthcare setting. The contribution made by this thesis include the development of: - A cost-of-illness analysis to estimate cardiovascular disease costs from the Irish health service perspective; - A cost-effectiveness model for the eradication of Helicobacter pylori using proton pump inhibitor (PPI) triple therapy in the Irish community setting; - A cost-effectiveness and cost-utility model of statin therapy for the primary prevention of coronary heart disease (CHD) in Ireland; and, - Extensive sensitivity analysis to address uncertainty in the primary prevention statin therapy model
The views of patients with severe chronic obstructive pulmonary disease on advance care planning:a qualitative study
Background: Chronic obstructive pulmonary disease (COPD) is a major cause of death worldwide and there are concerns that end-of-life care for these patients is inadequate. Advance care planning is encouraged, with the hope that it will improve communication and avoid unwanted interventions, which have been particular concerns; in practice, these discussions rarely occur. We have little knowledge of the views of patients with COPD on advance care planning. Understanding this could help integrate advance care planning into the routine management of patients with COPD. Aim: To explore the views of people with severe COPD about advance care planning. Design: Qualitative design, with data collection incorporating audio recorded semi-structured interviews. Analysis followed a grounded theory approach. Setting/participants: Patients with severe COPD (n = 10, Gold Standards Framework criteria) were recruited from primary and secondary care settings. Results: Participants felt they had not been given enough information about their diagnosis and prognosis, and were keen for more discussion with healthcare professionals. They wanted more involvement in decisions about their treatment when those decisions were required. Participants were happy to discuss their general views about future care, but felt uncomfortable with the traditional model of binding 'advance directives'. Conclusions: Considering advance care planning as a repeated process of discussion of prognosis, concerns and probable preferences for care would be more useful than encouraging binding advance decisions. Further research should assess the effectiveness of this approach. Local coordination of who is responsible for information provision is needed, and greater involvement of patients with COPD in management decisions as they arise
