🚑Comparative Healthcare Systems Unit 8 – Health Tech Assessment & Innovation

What's HTA & Why Should I Care?

• Health Technology Assessment (HTA) systematically evaluates the properties, effects, and impacts of health technologies or interventions
• Aims to inform policy and decision-making in healthcare by providing evidence-based insights on the clinical, economic, organizational, social, and ethical implications of adopting new technologies
  • Helps prioritize resource allocation and ensure value for money in healthcare spending
• Considers a wide range of factors beyond clinical effectiveness, such as cost-effectiveness, patient preferences, and societal implications
• Plays a crucial role in ensuring patient access to safe, effective, and affordable healthcare technologies
• Helps healthcare systems keep pace with rapid technological advancements while maintaining sustainability and equity
• Facilitates evidence-based decision-making and supports the development of clinical guidelines and reimbursement policies
• Contributes to the optimization of health outcomes and the overall performance of healthcare systems

Key Players in Health Tech Assessment

• Professional societies and medical associations
  • Contribute to the development of clinical guidelines and provide input on the relevance and acceptability of new technologies
• Patient organizations and advocacy groups
  • Represent patient perspectives and ensure that patient values and preferences are considered in HTA processes
• Industry stakeholders (pharmaceutical companies, medical device manufacturers)
  • Submit evidence and engage in dialogue with HTA bodies to support the assessment of their products
• International HTA networks (International Network of Agencies for Health Technology Assessment, European Network for Health Technology Assessment)
  • Foster collaboration, knowledge sharing, and harmonization of HTA practices across countries

HTA Process Breakdown

• Scoping and prioritization
  • Identifying and selecting technologies for assessment based on their potential impact and relevance to healthcare systems
• Evidence gathering and synthesis
  • Systematic review of available evidence on the safety, effectiveness, and cost-effectiveness of the technology
  • Includes data from clinical trials, observational studies, economic evaluations, and real-world evidence
• Stakeholder engagement
  • Consultation with relevant stakeholders (clinicians, patients, industry) to gather input and perspectives on the technology
• Appraisal and deliberation
  • Critical evaluation of the evidence and consideration of broader factors (ethical, social, organizational) by a multidisciplinary committee
• Recommendations and dissemination
  • Formulation of evidence-based recommendations on the adoption, use, or reimbursement of the technology
  • Communication of findings and recommendations to decision-makers, healthcare professionals, and the public
• Monitoring and re-evaluation
  • Ongoing monitoring of the technology's performance and impact in real-world settings
  • Periodic re-assessment to account for new evidence and changes in the healthcare landscape

Evaluating Health Tech: Methods & Metrics

• Clinical effectiveness
  • Assesses the extent to which a technology improves health outcomes compared to existing alternatives
  • Considers measures such as mortality, morbidity, quality of life, and patient-reported outcomes
• Safety
  • Evaluates the potential risks and adverse events associated with the use of the technology
  • Includes short-term and long-term safety data from clinical trials and post-market surveillance
• Cost-effectiveness
  • Compares the costs and health outcomes of the technology to determine its value for money
  • Uses metrics such as incremental cost-effectiveness ratios (ICERs) and quality-adjusted life years (QALYs)
• Budget impact
  • Estimates the financial impact of adopting the technology on healthcare budgets and resource allocation
• Organizational implications
  • Assesses the impact of the technology on healthcare delivery, workforce, and infrastructure
  • Considers factors such as training requirements, workflow changes, and capacity constraints
• Patient and societal perspectives
  • Incorporates patient preferences, values, and experiences in the evaluation process
  • Considers broader societal implications, such as equity, access, and ethical concerns
