OP04 Lessons Learnt When Implementing A Health Technology Assessment Institution In Costa Rica
Data_Sheet_1_A systematic review of the early dialogue frameworks used within health technology assessment and their actual adoption from HTA agencies.docx
IntroductionEarly advice in the process of developing health technologies allows manufacturers to plan their production and transfer to health care systems more accurately. This review aims to describe frameworks used within HTA and their current use by HTA Agencies.Material and methodsWe carried out a systematic literature review in Pubmed, Embase, Scopus, and WoS, including all references published in Spanish and English. This was last updated in March 2022. We extracted all available information regarding the organizations involved, services offered, types of technology, collaborators involved, fees, output and impact. Websites of several HTA organizations and Google were also searched in order to update and complete the information obtained from this generic search.ResultsFive-hundred and forty one articles were identified and screened, of which 26 met the eligibility criteria and were selected. Seven of them were non-systematic reviews that described two or more HTA organizations. Ten studies were focused on the advice offered by individual organizations, and eight described the EMA and EUnetHTA parallel or joint advice. We found variations in the technology assessed, services offered, stage of development and costs for advisory services.ConclusionsEarly and scientific advice would help manufacturers focus their product development on what is needed for the management of specific diseases. Most of the examples or services found refer to drugs as well as to some medical devices and diagnostics. A common definition of the type of advice that could be offered for different health technologies by HTA bodies to ascertain health care systems and manufacturers' needs, in addition to the timeline in which that advice needs to be given, would help HTA bodies provide the right support at the right time.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020219401, PROSPERO CRD42020219401.</p
Computed tomography versus invasive coronary angiography: design and methods of the pragmatic randomised multicentre DISCHARGE trial
Objectives
More than 3.5 million invasive coronary angiographies (ICA) are performed in Europe annually. Approximately 2 million of these invasive procedures might be reduced by noninvasive tests because no coronary intervention is performed. Computed tomography (CT) is the most accurate noninvasive test for detection and exclusion of coronary artery disease (CAD). To investigate the comparative effectiveness of CT and ICA, we designed the European pragmatic multicentre DISCHARGE trial funded by the 7th Framework Programme of the European Union (EC-GA 603266).
Methods
In this trial, patients with a low-to-intermediate pretest probability (10–60 %) of suspected CAD and a clinical indication for ICA because of stable chest pain will be randomised in a 1-to-1 ratio to CT or ICA. CT and ICA findings guide subsequent management decisions by the local heart teams according to current evidence and European guidelines.
Results
Major adverse cardiovascular events (MACE) defined as cardiovascular death, myocardial infarction and stroke as a composite endpoint will be the primary outcome measure. Secondary and other outcomes include cost-effectiveness, radiation exposure, health-related quality of life (HRQoL), socioeconomic status, lifestyle, adverse events related to CT/ICA, and gender differences.
Conclusions
The DISCHARGE trial will assess the comparative effectiveness of CT and ICA
CT or Invasive Coronary Angiography in Stable Chest Pain.
Background: In the diagnosis of obstructive coronary artery disease (CAD), computed tomography (CT) is an accurate, noninvasive alternative to invasive coronary angiography (ICA). However, the comparative effectiveness of CT and ICA in the management of CAD to reduce the frequency of major adverse cardiovascular events is uncertain.
Methods: We conducted a pragmatic, randomized trial comparing CT with ICA as initial diagnostic imaging strategies for guiding the treatment of patients with stable chest pain who had an intermediate pretest probability of obstructive CAD and were referred for ICA at one of 26 European centers. The primary outcome was major adverse cardiovascular events (cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke) over 3.5 years. Key secondary outcomes were procedure-related complications and angina pectoris.
Results: Among 3561 patients (56.2% of whom were women), follow-up was complete for 3523 (98.9%). Major adverse cardiovascular events occurred in 38 of 1808 patients (2.1%) in the CT group and in 52 of 1753 (3.0%) in the ICA group (hazard ratio, 0.70; 95% confidence interval [CI], 0.46 to 1.07; P = 0.10). Major procedure-related complications occurred in 9 patients (0.5%) in the CT group and in 33 (1.9%) in the ICA group (hazard ratio, 0.26; 95% CI, 0.13 to 0.55). Angina during the final 4 weeks of follow-up was reported in 8.8% of the patients in the CT group and in 7.5% of those in the ICA group (odds ratio, 1.17; 95% CI, 0.92 to 1.48).
Conclusions: Among patients referred for ICA because of stable chest pain and intermediate pretest probability of CAD, the risk of major adverse cardiovascular events was similar in the CT group and the ICA group. The frequency of major procedure-related complications was lower with an initial CT strategy.
