Health Technology Assessment: An In-Depth Analysis

Health Technology Assessments (HTA’s)

Health technology assessment (HTA) is a multidisciplinary process that evaluates the clinical effectiveness, safety, economic viability, and broader impact of health technologies. Health technologies refer to any intervention, such as medicines, vaccines, medical devices, procedures, and systems, used to prevent, diagnose, or treat a disease or condition that affects human health. HTAs are essential to ensure that technologies being considered for adoption are safe, effective, and can deliver the desired outcomes at a reasonable cost. By assessing the technological properties of health technologies, HTA also help healthcare systems identify promising innovations that can improve health outcomes and enhance patient care.

In a rapidly evolving healthcare landscape, HTA evaluation plays a crucial role in informing policy decision-makers, healthcare providers, and patients about the most effective and cost-efficient technologies to adopt. HTAs must be conducted in a structured and thorough manner. Therefore, the HTA process involves several steps, including systematic reviews, a review of the clinical evidence, economic evaluation, and budget impact estimation. This information should be unbiased and evidence based.

What is the basis for HTA in Ireland?

The Health Service Executive (HSE) has statutory responsibility for decisions on pricing and reimbursement of medicines in accordance with the 2013 Health Act. As part of this statutory assessment process the HSE must consider the affordability of each individual decision against overall resources as allocated. In line with the 2013 Health Act, if a Company would like a medicine to be reimbursed by the HSE the Company must first submit an application to the HSE.

In reaching its decision on the whether to include a new medicine on the reimbursement list, Part 3 of the 2013 Health Act requires the HSE to have regard to the following criteria:

• The health needs of the public
• The cost-effectiveness of meeting health needs by supplying the item concerned rather than providing other health services [2]
• The availability and suitability of items for supply or reimbursement
• The proposed costs, benefits and risks of the item or listed item relative to therapeutically similar items or listed items provided in other health service settings and the level of certainty in relation to the evidence of those costs, benefits, and risks [4]
• The potential or actual budget impact of the item or listed item [5]
• The clinical need for the item or listed item
• The appropriate level of clinical supervision required in relation to the item to ensure patient safety
• The efficacy (performance in trial), effectiveness (performance in real situations) and added therapeutic benefit against existing standards of treatment (how much better it treats a condition than existing therapies)
• The resources available to the HSE.

Three of the above criteria are included in a HTA: comparative clinical effectiveness (4), cost effectiveness (2) and budget impact (5).

In submitting an application for reimbursement, a Company will propose a price for reimbursement having regard, as applicable, to this Framework Agreement 2021 (an agreement between the Irish Pharmaceutical Healthcare Association (IPHA) and the HSE regarding the pricing and supply of medicines.

What qualifies as a health technology??

The term ‘health technology’ encompasses a wide range of health interventions. ‘Technology’ includes any intervention that may be used to promote health; to prevent, diagnose or treat a disease; or in rehabilitation or long-term care.

Technologies include, but are not limited to:

• Medicines, including vaccines
• Medical devices, including equipment such as surgical robots and implantable devices
• Diagnostic tests, for example, tests to detect colorectal cancer
• Surgical procedures, such as coronary artery bypass
• Public health interventions, for example, a colorectal cancer screening programme
• Support systems, such as electronic patient records
• Organisational features, for example, the establishment of centres of excellence.

A health technology does not have to be a medical intervention given directly to a patient. It may be as broad as a restructuring of how an aspect of the health service is organised and delivered, such as the transfer of a service from secondary to primary care settings. The technology does not need to be new, and a HTA can look at changing existing services through reallocation of resources or through standardising current services. A HTA can also be used to inform decisions about discontinuing ineffective technologies and, thereby, support the best use of available resources.

Who carries out HTAs in Ireland?

HTAs are carried out by a range of public bodies and research groups.

• The Health Information and Quality Authority (HIQA) is mandated under the Health Act to carry out HTAs and develop guidelines for HTA preparation across the Irish health system (this includes pharmaceuticals, devices, diagnostics, procedures, care pathways and public health activities). They also undertake HTAs to inform national-level policy decisions and national health service decisions.
• The National Centre for Pharmacoeconomics (NCPE) is commissioned by Corporate Pharmaceutical Unit of the Health Service Executive (HSE-CPU) to perform HTAs on pharmaceutical products, in particular on whether new treatments should be made available at the state’s expense. All new medicines are required to undergo a rapid review (RR) appraisal by the NCPE. Following this, high-cost medicines or those predicted to have a significant budget impact then undergo a full HTA appraisal by the NCPE. The NCPE also work with other HTA bodies such as HIQA as well as engaging in research with academic units.
• The HSE assesses the clinical and cost-effectiveness of medical devices being introduced to the market.
• The pharmaceutical industry undertakes HTAs in support of applications to have products reimbursed through the Community Medicines Schemes and hospitals. These are appraised by the NCPE.
• Academic groups undertake HTAs on behalf of the healthcare industry and for research purposes.

What is evaluated in a HTA??

The content of a HTA will vary depending on the decision being supported. For example, a full HTA to support a national decision will typically collect and summarise evidence under a number of headings. These headings include:

• Description of the technology – what it is used for and how it works.
• Burden of disease – who gets the disease and what are the typical outcomes.
• Clinical effectiveness and safety –this includes data form clinical trials, real-world studies and systematic reviews
• Cost-effectiveness and budget impact – the economic evaluation is a crucial component of the HTA. It analyses and evaluates the costs and benefits associated with the intervention and helps determine whether the intervention provides value for money in relation to its health outcomes. The financial impact is also assessed and involves the costs associated with the implementing and delivering the intervention and its potential impact on the overall healthcare budget.
• Organisational and social aspects – how does the technology impact on patients and the organisation of services.
• Ethical and legal issues – HTA considers ethical and societal considerations associated with the intervention. This may include evaluating issues such as equity of access, patient preferences, impact on vulnerable populations, and the broader societal implications of adopting the intervention.

There are recommended guidelines around the evidence required under these particular headings. Each of these areas is important. For ease of use, the national guidelines have been developed as stand-alone documents.

Guidelines for Economic Evaluation of Health Technologies in Ireland

Guidelines for Evaluating the Clinical Effectiveness of Health Technologies in Ireland

Guidelines for the Budget Impact Analysis of Health Technologies in Ireland

The guidelines are intended to be applicable to all healthcare technologies, including pharmaceuticals, procedures, medical devices, broader public health interventions and service delivery models. It is important to refer to the most up-to-date version of these guidelines.

The HTA Process

A summary of the HTA process from the NCPE website is outlined in Fig.?1?and the text below. The formal reimbursement process begins once the applicant company receives a positive decision from the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) and they have certainty around the reimbursement price for which they intend to apply.

The HTA process, following CHMP opinion, consists of several steps:

• The company makes a Rapid Review (RR) submission to the NCPE in accordance with NCPE requirements. Each submission pertains to one medicine for one indication.
• The NCPE review group appraises the RR submission within a 4-week timeframe. The decision criteria considered by the NCPE during the RR appraisal includes eligible patient population, robustness of clinical evidence, cost of the medicine relative to current standard of care and budget impact.
• The NCPE informs the HSE-CPU as to whether an HTA is required and notifies the applicant company when the RR is completed, and that the outcome will be posted on the NCPE website.
• Where an HTA has been deemed necessary, a pre-submission consultation is arranged between the NCPE and the applicant company. The pre-submission meeting provides an opportunity for the applicant company and the NCPE to discuss what will be included in the HTA submission.
• The applicant company produces an HTA submission in accordance with NCPE requirements and HIQA guidelines.
• The NCPE may seek clarification from the applicant company on any aspect of the submission. Preliminary questions are sent to the applicant company once the NCPE have conducted a thorough review of the submission. The applicant company is requested to respond to the questions within 1 month.
• The appraisal of the HTA should take a maximum of 90 days, excluding the time taken by the applicant company to prepare the submission and to make any required amendments. A draft appraisal report is sent back to the applicant company for a factual accuracy check, which should be carried out within 5 working days.
• The final appraisal report is produced. Where cost effectiveness has been demonstrated, a positive reimbursement recommendation is made. If the medicine is not considered cost effective at the submitted price, this is specified. If it is not considered cost effective because of unresolved concerns about the validity of any aspect of the submission, this is detailed. Further information on the updated NCPE recommendations can be found on the NCPE website.
• The final appraisal report is sent to the HSE-CPU. The HSE considers the appraisal report in conjunction with the additional criteria set out in the Health Act 2013.
• For certain medicines, a final decision can be reached, and the applicant company notified. In most cases, the medicine will be considered by the HSE Drugs Group, who will make a reimbursement recommendation to the HSE Leadership Team, who in turn make the reimbursement decision.

Salutem Insights have created a short video to summarise the reimbursement process here :?Understanding the Irish Reimbursement Process for Medicines

It is important to note that the HTA process in Ireland is continually evolving, and the specific steps and bodies involved may vary depending on the specific intervention and circumstances. However, the overall aim remains to ensure that healthcare technologies are evaluated in a rigorous, transparent, evidence-based and equitable manner to facilitate informed decision-making and optimise healthcare resource allocation in Ireland.

Timelines

From the Salutem Insights database the timeframe between RR submission and reimbursement has varied over time for new medicines that have undergone a HTA (see Fig. 2). For example, in 2010, the average time between RR submission and reimbursement was 290 days compared to 829 days in 2022. These timelines do not take into account the NCPE stop-clock process and the time it takes to submit a HTA to the NCPE following the outcome from the RR.
