Generative AI for Health Technology Assessment: Opportunities, Challenges, and Policy Considerations - an ISPOR Working Group Report

ObjectiveTo provide an introduction to the uses of generative Artificial Intelligence (AI) and foundation models, including large language models (LLMs), in the field of health technology assessment (HTA). MethodsWe reviewed applications of generative AI in three areas: systematic literature reviews, real world evidence (RWE) and health economic modeling. Results(1) Literature reviews: generative AI has the potential to assist in automating aspects of systematic literature reviews by proposing search terms, screening abstracts, extracting data and generating code for meta-analyses; (2) Real World Evidence (RWE): generative AI can facilitate automating processes and analyze large collections of real-world data (RWD) including unstructured clinical notes and imaging; (3) Health economic modeling: generative AI can aid in the development of health economic models, from conceptualization to validation. Limitations in the use of foundation models and LLMs include challenges surrounding their scientific rigor and reliability, the potential for bias, implications for equity, as well as nontrivial concerns regarding adherence to regulatory and ethical standards, particularly in terms of data privacy and security. Additionally, we survey the current policy landscape and provide suggestions for HTA agencies on responsibly integrating generative AI into their workflows, emphasizing the importance of human oversight and the fast-evolving nature of these tools. ConclusionsWhile generative AI technology holds promise with respect to HTA applications, it is still undergoing rapid developments and improvements. Continued careful evaluation of their applications to HTA is required. Both developers and users of research incorporating these tools, should familiarize themselves with their current capabilities and limitations.

Ethical challenges for Health Technology Assessment (HTA) in the evolving evidence landscape.

Since its inception, Health Technology Assessment (HTA) has typically determined the value of a technology by collecting information derived from randomized clinical trials (RCTs), in line with the principles of evidence-based medicine (EBM). However, data from RCTs did not constitute the sole source of information, as other types of evidence (such as primary qualitative research) have often been utilized. Recent advances in both generating and collecting other types of evidence are broadening the landscape of evidence, adding complexity to the discussion of "robustness of evidence." What are the consequences of these recent developments for the methodology and conduct of HTA, the HTA community, and its ethical commitments? The aim of this article is to explore some ethical challenges that are emerging in the current evolving evidence landscape, particularly changes in evidence generation and collection (e.g., diversification of data sources), and shifting standards of evidence in the field of HTA (e.g., increasing acceptability of evidence that is thought of as lower quality). Our conclusion is that deciding how to best maintain trustworthiness is common to all these issues.

OP23 Early Detection Tools For Emotional Distress In Adult Cancer Patients In Spain: A Health Technology Assessment Report

IntroductionPatient-reported outcome measures are being increasingly considered both in clinical practice and in the field of health technology assessment. Although emotional distress is currently recognized as the sixth vital sign in cancer care, its early detection and screening is not yet included in routine clinical practice in Spain. The main objective of this study was to assess the psychometric properties and diagnostic accuracy of validated tools for the early detection of distress among adults with cancer in the Spanish context, at the request of the Spanish National Health System (NHS) Cancer Strategy.MethodsA systematic review was carried out to analyze development and validation studies. The Quality Assessment of Diagnostic Accuracy Studies tool (QUADAS-2) was used for the risk of bias assessment, and a multicriteria global assessment was used for the tests. Ethical and organizational aspects were also addressed.ResultsFifteen validation studies were included, corresponding to seven tests. The tools considered were the Distress Thermometer (DT), the Brief Symptom Inventory-18 (BSI-18), the Edmonton Symptom Assessment System-revised (ESAS-r), the Hospital Anxiety and Depression Scale (HADS), the Visual Analog Scale for Anxiety and Depression (VAS-AD), the Detection of Emotional Distress (DED) scale, and the Psychosocial and Spiritual Needs Evaluation (ENP-E) scale. Evidence of validity, reliability (internal consistency), and diagnostic accuracy (sensitivity, specificity, and area under the receiver operating characteristic curve) were summarized. Three scales were rated as poor (VAS-AD, BSI-18, and ESAS-r), the ENP-E scale was rated as acceptable, and three scales were rated as moderate (DT, DED, and HADS).ConclusionsThe DT (single-item measure) stands out as an appropriate tool for early detection of emotional distress in the Spanish NHS. The use of this scale could be considered a first stage, to be combined later with a longer scale to improve screening specificity. The HADS scale could be utilized for this purpose. The use of these tools should be framed within a structured screening program that ensures further evaluation and subsequent psychological care when needed.

PP14 The Role Of Health Technology Assessment In The Public Hospitals Of The National Health Service Of Catalonia

IntroductionHospitals play an essential role to facilitate the appropriate introduction of health technologies into the National Health System. We aimed to analyze if the decision-making at the hospital level is based on health technology assessment (HTA).MethodsWe developed a seventeen-question survey to assess the decision-making mechanisms for the introduction of health innovation into the public hospitals of the National Health Service (NHS) of Catalonia. All questions were related to the field of HTA and health innovation. We asked about the process of new health technology acquisition, the existence of HTA units, and the impact those units might have within the center. We invited the three main public healthcare providers (n= 68 centers). We performed a quantitative analysis grouping the results by type of healthcare provider.ResultsThirty-five different health providers (51.5%) remitted forty-two responses. We identified two differential mechanisms for the introduction of health innovation in those centers: 51.4 percent used a directive committee for decision-making, whereas 37.1 percent employed a technical commission. Some centers (8.6%) used both options. Both the directive committees and technical commissions predominantly considered the professional experience or scientific evidence provided by the healthcare professionals of the center (80%) or external HTA reports or clinical practice guidelines (65.7%) to guide their decision-making. Using HTA products developed within the center was less frequent (34.3%). Only 57.1 percent of the healthcare providers had an HTA unit, but 75 percent of them declared that HTA products had a direct and quantifiable impact on their decision-making regarding the introduction of innovation. Healthcare providers without HTA units manifested their willingness to adopt HTA practices into their decision-making processes.ConclusionsHTA at the hospital level is not a common practice when deciding to introduce innovative health technologies in the NHS of Catalonia. However, the main healthcare providers agreed that the introduction of HTA is necessary for improving their decision-making and that the HTA agency, Agency for Health Quality and Assessment of Catalonia (AQuAS) will play a key role (training, promoting, and assessing).

OP88 Drawing Lines In The Sand: How Do We Define The Scope Of Analysis In HTA And Economic Evaluation?

IntroductionWe explore how the scope of analysis is defined in health technology assessment (HTA) and economic evaluation and consider the potential implications of these decisions.MethodsThe scope of analysis, including decisions about which methods and domains of HTA to include in the assessment, which costs, and health outcomes are most meaningful, and which comparators are the most relevant are typically informed by the needs of the decision-maker. We undertook two systematic scoping reviews to assess: (i) to what extent systems thinking is considered in literature-based technology assessments; and (ii) how the scope of the analysis is defined in economic evaluation using Clostridioides difficile infection as an exemplar. We synthesized the findings from these reviews and offer three key observations for future research and exploration in the field of HTA.ResultsOur scoping reviews found that the scope of analysis in economic evaluations typically focus on single interventions, often ignoring upstream and downstream interventions. Similarly, published technology assessments have narrowly defined and inconsistent scopes of analysis, with limited consideration of indirect health and non-health impacts. Three key observations for the field of HTA include: (i) economic evaluations focus on the value of single heath interventions. A focus on a single health intervention may simplify the analysis; however, will this siloed decision-making lead to optimal health resource allocation? (ii) published assessments have inconsistently defined scopes of analysis. A decision problem that focuses on the needs of the decision-maker is practical; however, will inconsistencies in perspectives across assessments create unfair conceptualizations of value? (iii) HTA is technology-focused, not patient-focused. A technology-focused HTA system aligns with the technology diffusion process; however, does this move us away from the patient-centered mandate of HTA?ConclusionsThe dynamic nature of HTA leads to many conceptualizations of value. Considering the potential implications of narrowly defined, inconsistent, and technology-focused scopes of analyses may have consequences on achieving a patient-centered high-quality health system.

The Vital Role of Medical Librarians in a Time of Information Overload


 This October is Canadian Library Month, which underscores the value of libraries and medical librarians as trusted sources in a world of information overload.
 The changing information landscape has served to transform the role of medical libraries and librarians and to highlight their crucial role in supporting rigorous scientific research.
 Medical librarians who specialize in the field of health technology assessment have taken on the role of monitoring the evolving landscape of information sources and technological advancements.
 Building communities of practice among health technology assessment librarians offers opportunities to strengthen skill sets, discuss methodological standards in information retrieval, and nurture broad participation in these conversations.

Reimagining Pharmaceutical Market Exclusivities: Should the Duration of Guaranteed Monopoly Periods Be Value Based?

ObjectivesTo describe the main features of a pharmaceutical market in which the duration of guaranteed monopoly periods would correspond to a new pharmaceutical product’s value. MethodsAfter reviewing patent and regulatory exclusivity-based mechanisms for protecting prescription drug markets from competition to incentivize drug innovation in developed countries, we model market protection mechanisms within the current framework to give the longest-lasting market protections to drug developers that bring the most affordable products to market with highest public health and clinical value. ResultsAn approach tying pharmaceutical market exclusivity to value would have 3 main features. First, it would be based on regulatory exclusivity (ie, the drug regulator refrains from authorizing generic entry for a certain amount of time), rather than patents. Second, the duration of exclusivity period would be pegged to the magnitude of a product’s anticipated health impact and its proposed price by using modified methods from the field of health technology assessment. Third, the duration of the value-based exclusivity period would be reassessed routinely 3 years after the product’s launch to account for its real-world effectiveness. ConclusionsLinking a drug’s proposed price to the duration of its regulatory-based exclusivities would both incentivize the development of high impact, low-cost products and motivate drug developers to introduce these products at lower prices.

Cost-effectiveness of Growth Hormone and its Consumption Indications: A Systematic Review of Economic Evaluation Studies

Context: Growth hormone deficiency (GHD) is one of the main reasons for short stature in children, which can be treated by early diagnosis. Stature is an appropriate measure to assess a child’s overall growth and health, and one’s height can affect his psychosocial and social well-being. Human growth hormone (HGH) has extensive effects on biological processes as well as height. Due to the high cost of growth hormone (GH) drugs, in most countries GH is prescribed according to scientific indications. Methods: The present study was a systematic review, which examined PICOD- based case studies published from the beginning of 2002 to February 2019 on Web of Science, PubMed, Scopus, SID, Embase, and Magiran databases in the field of health technology assessment and the economic evaluation. According to the inclusion criteria, 11 relevant articles were selected in the present study. Results: The findings showed that GH therapy was effective in increasing patients’ quality of life, and that the growth rate of children treated with GH was more than 2.5 cm per year, in comparison to the control group. Furthermore, the results of the studies indicated the cost-effectiveness of GH since the cost of each centimeter height increase in children was on average US $20,000, and the incremental cost effectiveness ratio varies based on QALY’s criteria in studies for various indications (Turner syndrome, idiopathic short stature, growth hormone deficiency, Prader Willi syndrome, Infants small for gestational age (SGA), chronic renal failure (CRF) and (SHOX-D). The highest cost efficacy per QALY was for growth hormone deficiency (from £20,000 to £30,000), and the lowest cost efficacy is for Prader Willi (from £55,000 to £135,000). Conclusions: Studies showed that GH increases the height of the children treated with GHD, compared to the control children; hence, the use of growth hormone is recommended after doing the experiments for all children with GHD. This issue can be considered by health policy makers to implement in healthcare programs.

An institutional ethnographic analysis of public and patient engagement activities at a national health technology assessment agency.

The practice of public and patient engagement (PPE) in health technology assessment (HTA) has spread worldwide, yet gaps in knowledge remain. We carried out an institutional ethnography of the Canadian Agency for Drugs and Technologies in Health (CADTH) public and patient involvement in HTA. The research took place over 15 months and included observational work in the institutional settings, text review, and interviews with individuals working for or involved with the agency. We found that despite demonstrated commitment to PPE, organizational history, governance structure, and practices were impediments to a unified approach to PPE. Unclear role descriptions for committee members and differences in philosophy and priority given to PPE across the organization presented challenges to effective participation. The high degree of value given to evidence-based principles at times conflicted with meaningful integration of patient input. A lack of clear goals and processes, roles, and differential treatment of evidence in PPE served to minimize the importance of patient experiences and to displace their validity. An acknowledgment of conflicts between multiple epistemic traditions at work within HTA activities may strengthen organizational approaches to PPE. HTA organizations can learn from this study by reflecting on the challenges described and the recommendations offered to address them. We suggest solidifying CADTH's commitment to PPE with clear agency-wide roles and direction, values, and outcomes, a comprehensive framework, and policy and procedures. An acknowledgment of diverse epistemic traditions, as well as leadership and expertise in PPE, will strengthen CADTH's PPE activities and sustain its leadership position in the HTA field.

Development of a decisional flowchart for meaningful patient involvement in Health Technology Assessment.

This paper aims to describe the development of a flowchart to guide the decisions of researchers in the Spanish Network for Health Technology Assessment of the National Health System (RedETS) regarding patient involvement (PI) in Health Technology Assessment (HTA). By doing so, it reflects on current methodological challenges in PI in the HTA field: how best to combine PI methods and what is the role of patient-based evidence. A decisional flowchart for PI in HTA was developed between March and April 2019 following an iterative process, reviewed by the members of the PI Interest Group and other RedETS members and validated during an online deliberative meeting. The development of the flowchart was based on a previous methodological framework assessed in a pilot study. The guidelines on how to involve patients in HTA in the RedETS were graphically represented in a flowchart. PI must be included in all HTA reports, except those that assess technologies with no relevant impact on patients' experiences, values, and preferences. Patient organizations or expert patients related to the topic of the HTA report must be identified and invited. These patients can participate in protocol development, outcomes' identification, assessment process, and report review. When the technology assessed affects in a relevant way patient experiences, values, and preferences, patient-based evidence should be included through a systematic literature review or a primary study. The decisional flowchart for PI in HTA contributes to the current methodological challenges by proposing a combination of direct involvement and patient-based evidence.

Core competencies for ethics experts in health technology assessment.

There is no consensus on who might be qualified to conduct ethical analysis in the field of health technology assessment (HTA). Is there a specific expertise or skill set for doing this work? The aim of this article is to (i) clarify the concept of ethics expertise and, based on this, (ii) describe and specify the characteristics of ethics expertise in HTA. Based on the current literature and experiences in conducting ethical analysis in HTA, a group of members of the Health Technology Assessment International (HTAi) Interest Group on Ethical Issues in HTA critically analyzed the collected information during two face-to-face workshops. On the basis of the analysis, working definitions of "ethics expertise" and "core competencies" of ethics experts in HTA were developed. This paper reports the output of the workshop and subsequent revisions and discussions online among the authors. Expertise in a domain consists of both explicit and tacit knowledge and is acquired by formal training and social learning. There is a ubiquitous ethical expertise shared by most people in society; nevertheless, some people acquire specialist ethical expertise. To become an ethics expert in the field of HTA, one needs to acquire general knowledge about ethical issues as well as specific knowledge of the ethical domain in HTA. The core competencies of ethics experts in HTA consist of three fundamental elements: knowledge, skills, and attitudes. The competencies described here can be used by HTA agencies and others involved in HTA to call attention to and strengthen ethical analysis in HTA.

PP288 Health Technology Assessment In Universal Health System: A Network At The Brazilian Capital

IntroductionCollaborative networking is adopted to implement health technology assessment (HTA) in academic and research institutions and exchange knowledge with hospitals and health services. Since 2016, the District Network for Health Technology Assessment (ReDAPTS) has been dedicated to generating and promoting evidence that supports decision-making, promoting continuous qualification, supporting and guiding managers in priorities and demands, analysing the economic, ethical and social implications of problems and situations, and contributing to healthcare quality at the Unified Health System. The objective of this study is to present the construction process of ReDAPTS from 2016 to 2019.MethodsThis experience report about ReDAPTS considered three main actions: (i) situational diagnosis in 2016 and 2017, (ii) agreements of internal regulation and governance and (iii) HTA training strategies for professionals. The scientific events and executive group meetings were described to identify the strategies for the implementation of a collaborative network in the Federal District (FD), Brazil.ResultsIn total, fifteen institutions were identified with a potential to develop the HTA field at the district level. Between 2016 and 2019, three scientific events, eighteen technical meetings for network governance and two scientific meetings were carried out, organized by ReDAPTS and with 269 participants, highlighting assistance and university hospitals, FD Department of Health and academic and research institutions. Four HTA courses were offered and 319 professionals from the FD were trained.ConclusionsCollaborative networking provided strengthening capacity for study production and debates on institutional processes for public health policies at the FD. Networking encouraged collaboration between institutions and promoted sharing HTA experiences. The network faces challenges to operate with full capacity. Political and institutional commitment, physical infrastructure and trained personnel sustainability are key to maintaining the HTA process at the FD. Institutions can develop HTA-teams to promote continuous qualification, study production and the rational use of technologies.

Evaluating Public Health Interventions: A Neglected Area in Health Technology Assessment.

Introduction: Public health (PH) interventions are crucial for ensuring sustainable healthcare services. Nevertheless, they represent a neglected area in the field of health technology assessment (HTA) due to various methodological issues and their complex design that goes beyond clinical setting. The present study provides an environmental scan of HTA initiatives related to the assessment of PH technologies on a global level.Methods: We conducted a cross-sectional survey among 85 HTA-related European and international societies, health bodies, and networks from September 2018 to January 2019. The questionnaire contained four sections and 18 questions regarding activities related to the evaluation of PH technologies, information on existing PH technologies, and methodologies of assessment as well as barriers and facilitators to reaching a decision and implementing a PH technology.Results: Among 52 survey responses, the majority of the respondents came from European countries (35%), followed by North American (27%), and South American (19%) countries. The main type of organizations covered by our survey included HTA agencies, public administrations, and research institutes. Seventy-one % of the institutions reported engagement in any aspect of HTA in the area of PH (N = 37). Among those, 81% evaluated less than 5 PH technologies from 2013 to 2018. The most common barriers for reaching a decision on PH technologies were lack of data, conflicting stakeholder priorities, and methodological issues. A total of 76 PH interventions were reported, and most cited initiatives were related to chronic disease screening, prevention of infectious diseases, and maternal, prenatal, and neonatal screening.Conclusion: Our survey reported a rather limited involvement of HTA in the evaluation of PH technologies. In particular, an evaluation of behavioral and lifestyle interventions remains extremely rare. The implementation of collaborative HTA approaches in the setting of PH practice and policy needs to be prioritized and further strengthened. Moreover, ensuring reliable data structures and consolidation of HTA methods for the evaluation of PH technologies will be crucial for tackling the enormous burden of non-communicable diseases in societies.

Policy developments of health technology assessment in the European Union

The purpose of the note below is to familiarize readers with the current status and future initiatives of cooperation in the field of health technology assessment (HTA) in the European Union (EU). The European Commission is trying to create a framework for efficient collaboration between member states of EU in the field of HTA and is gradually working on strengthening it. The following initiatives, projects and programs have already been implemented: - Project on Coordination and Development of Health Care Technology Assessment in Europe - The European Collaboration for Assessment of Health Interventions and Technology - European Network for Health Technology Assessment - Beneluxa Initiative, The Valletta Declaration, FINOSE and Fair and Affordable Pricing - European Network for Health Technology Assessment Currently there is an ongoing proposal for an HTA Regulation of the European Parliament and the Council, which is the measurable result of this cooperation. A key element of the proposed regulation is a centralized joint clinical assessment (for HTA purposes) of the efficacy of the medicinal product/medical device.

Tackling the 3 Big Challenges Confronting Health Technology Assessment Development in Asia: A Commentary

There has been continuous development in the field of health technology assessment (HTA) owing to the added value of HTA in supporting healthcare reimbursement decisions. Collaboration and engagement among countries in Asia has been carried out to share experiences and learning on the barriers and factors facilitating the implementation and use of HTA in policy making. A symposium on the topic of Health Technology Assessment (HTA): Selecting the Highest Value Care was held on January 10, 2019 at the National University of Singapore, during which 3 major challenges confronting HTA development in Asia were identified. The symposium also offered possible ways to overcome the challenges.

Scientific methodology and practical use of managed entry agreements for innovative medicines in system of health technology assessment in Ukraine

In the Health Technology Assessment (HTA) system, it is advisable to use a mini-HTA to save budget funds at the hospital level, taking into account real world data on drug consumption for a rational use of resources at the local level. HTA include Managed Entry Agreements (MEA), which is being actively implemented in Europe to ensure the availability of innovative medicines for the treatment of oncological, hematological, rare diseases, assisted reproductive technologies (ART), and government funding programs.
 The aim of this study was to analyze the use of the mini-HTA approach for the evaluation of innovative drugs, in particular with ART. Theoretically and practically substantiate the «Managed Entry Agreement» methodology for innovative drugs for rapid availability to new medicines based on evidence-based medicine and pharmacoeconomics for implementation at the state (local) level and rational use of budget funds.
 Research methods – systematic analysis of data of reports, publications about the mini-HTA and the «Managed Entry Agreement» in the leading countries of Europe. The main objects were articles, reviews of pharmacoeconomists of ISPOR, LSE, which are leading in the HTA field in the world. The statistical data on innovative drugs, included in the legislatively regulated by the MEA in the EU, Central and Eastern Europe countries, using the methods of generalization, systematic analysis were studied.
 We summarized the HTA data include in mini-HTA reports in EU countries, which were legally regulated and included innovative drugs for the treatment of cancer, hematological and rare diseases. We established that using 6 main MEA methods, regulated by law in the EU countries. There is necessary to create a recommendation on mini-HTA and MEA to improve the regulatory framework and activities of the HTA Department of State Expert Centre, MoH of Ukraine in order to implementation of the State strategy for implementing the State policy of providing the population with medicines for the period up to 2025.
 We formulated the term «mini-HTA» as a systematic process of evaluating indicators of effectiveness, safety, quality of life, social and ethical aspects in relation to the costs for innovative drugs to save budget resources at the local level. There is advisable to use the MEA methods to estimate the cost for treatment regimens, including drugs for ART, which will ensure the rational use of funds for state programs, in particular, for the treatment of infertility, and public health resources.

Proposal for a regulation on health technology assessment in Europe – opinions of policy makers, payers and academics from the field of HTA

ABSTRACT Introduction: In January 2018 the European Commission published a Proposal for a Regulation on Health Technology Assessment (HTA): ‘Proposal for a Regulation on health technology assessment and amending Directive 2011/24/EU’. A number of stakeholders, including some Member States, welcomed this initiative as it was considered to improve collaboration, reduce duplication and improve efficiency. There were however a number of concerns including its legal basis, the establishment of a single managing authority, the preservation of national jurisdiction over HTA decision-making and the voluntary/mandatory uptake of joint assessments by Member States. Areas covered: This paper presents the consolidated views and considerations on the original Proposal as set by the European Commission of a number of policy makers, payers, experts from pricing and reimbursement authorities and academics from across Europe. Expert commentary: The Proposal has since been extensively discussed at Council and while good progress has been achieved, there are still divergent positions. The European Parliament gave a number of recommendations for amendments. If the Proposal is approved, it is important that a balanced, improved outcome is achieved for all stakeholders. If not approved, the extensive contribution and progress attained should be sustained and preserved, and the best alternative solutions found.

PP194 Intersectoral Costs And Benefits In The Societal Perspective

IntroductionMany health care interventions have costs and benefits that spill over to sectors outside the healthcare sector. Little is known about these inter-sectoral costs and benefits (ICBs). However, to achieve an efficient allocation of scarce resources, insights on ICBs are indispensable. The main objective of this study was to identify the ICBs related to health care and provide a sector-specific classification scheme for these ICBs. For this sector-specific classification scheme mental disorders were taken as an example, as we expect that this is the sector with the most ICBs.MethodsUsing PubMed, a literature search was conducted for ICBs of mental disorders and related (psycho)social effects. A policy perspective was used to build the scheme's structure, which was adapted to the outcomes of the literature search. In order to validate the scheme's international applicability inside and outside the mental health domain, semi-structured interviews were conducted with (inter)national experts in the broad fields of health care.ResultsThe searched-for items appeared in a total of fifty-two studies. The ICBs found were classified in one of four sectors: “Education”, “Labor and Social Security”, “Household and Leisure” or “Criminal Justice System”. Psycho(social) effects were placed in a separate section under “Individual and Family”. Based on interviews, the scheme remained unadjusted, apart from adding a population-based dimension.ConclusionsThis is the first study which offers a sector-specific classification of ICBs. Given the explorative nature of the study, no guidelines on sector-specific classification of ICBs were available. Nevertheless, the classification scheme was acknowledged by an international audience and could therefore provide added value to researchers and policymakers in the field of health technology assessment. The identification and classification of ICBs offers decision makers supporting information on how to optimally allocate scarce resources. By exploring a new area of research, which has remained largely unexplored until now, the current study has an added value as it may form the basis for the development of a tool which can be used to calculate the ICBs of health care interventions.

PP125 PhotoVoice: Promoting Knowledge Exchange About Patients’ Experiences

IntroductionIn the past decades the community-based participatory research method known as PhotoVoice has gained relevance, but there are few published studies on its application in the field of health technology assessment (HTA) and clinical practice guidelines (CPGs). The aim of this presentation was to describe a PhotoVoice project linked to a CPG on major depression in children and adolescents.MethodsThe design of the study was adapted to the main objective, which was to enhance the understanding of major depression and improve clinical practice with the contributions of clinicians, methodologists, and patients. Seven adolescents and ten of their family members participated in the study through PhotoVoice sessions and focus groups. The audio recordings of all sessions were transcribed verbatim and coded, and a thematic analysis was undertaken.ResultsSix themes emerged: (i) a lack of understanding and information about depression in childhood and adolescence; (ii) the importance of support groups; (iii) the need to favor early care and access to services; (iv) the adaptation of therapeutic strategies tailored to individual needs; (v) the sensitivity of professionals; and (vi) fostering interaction between the health and education systems. Photographic exhibitions were planned to share the main results. These exhibitions were promoted to increase public awareness and reduce stigmatization, and to reach clinicians and policy makers. From a methodological point of view, the use of PhotoVoice in this study helped to effectively incorporate the lived experiences, concerns, and preferences of patients and their relatives into the CPG. The study also confirmed the value of photographs and participatory methods. The main limitations and strengths of the study, as well as suggestions for future research, are also outlined.ConclusionsPhotoVoice is a flexible, effective, and innovative method of obtaining information about patients’ perspectives and experiences, and it offers the added value of being able to reach the main stakeholders, including policymakers and the public.

PP08 Evaluation Of The Brazilian Health Technology Assessment Network

IntroductionThe Brazilian Network for Health Technology Assessment (REBRATS) is a network of collaborating centers and teaching and research institutions, focused on the generation and synthesis of scientific evidence in the field of health technology assessment. Currently, the network is composed of 119 member institutions and mobilizes approximately 1,094 researchers and 4,998 relations. The objective of this study was to evaluate the member institutions of REBRATS.MethodsThe evaluation process was developed in seven stages, including the identification of the objectives of the Network; identification of evaluation criteria; selection of performance indicators for each criterion; identification of the measures appropriate to each indicator; data collection and analysis; classification of the institutions and production of the final report.ResultsThe evaluation of the member institutions of REBRATS mapped the capacity of these institutions to produce health technology assessment activities. The evaluation also provided information on the advances and challenges of health technology assessment in the country. In the long term, the initiative will contribute to the strengthening of the evaluation of health technology in Brazil, since the weaknesses of these institutions in the development of activities were mapped.ConclusionsThe production of this study will contribute to the dissemination of the evaluation methodology at the national and international level. This study is one of the few initiatives that exist in the world on the evaluation of networks and will contribute to the strengthening of the evaluation of health technology in Brazil.
