PP151 VALIDATE Methodology On A Medication-Related Clinical Decision Support System: Holistic Assessment For Optimal Technology Adoption
Authors: Barcelo Carla Fernandez , Calvo-Cidoncha Elena , Sampietro-colom Laura 
Published: December 2022

IntroductionIn the past decade, health technology assessment (HTA) has narrowed its scope to analyses of mainly clinical and economic benefits. Technology challenges in the 21st century emphasize the need for holistic assessments to obtain accurate recommendations for decision-making, as in HTA’s foundations. Using the VALues In Doing Assessments of health TEchnologies (VALIDATE) methodology for complex technologies provides a deeper understanding of problems through analysis of stakeholders’ views, allowing for more comprehensive HTAs. This study aimed to assess a pharmaceutical clinical decision support system (CDSS) using VALIDATE.MethodsSemi-structured interviews with different stakeholders were conducted in the following domains: problem definition (medication error [ME] occurrence and prevention); judgement of solution (existing preventive methods and previous experiences of the CDSS); background theories (future impact and personal beliefs); and barriers to and facilitators of implementation. The following individuals were interviewed: medical informatic specialists (n=3), pharmacists (n=2), nurses (n=2), physicians (n=2), CDSS company representatives (n=1), electronic health record developer (n=1), and health consultancy firm representatives (n=1). Content analysis was used to integrate and analyze the data.ResultsThe multistakeholder interviews identified various barriers to the acceptance and implementation of a pharmaceutical CDSS that were different from those reported in the literature. These included: (i) occurrence of ME (no traceability of medication taken or poor patient medication empowerment); (ii) perception of current level of MEs (huge improvement from ten years ago); (iii) perception of technology as a tool to prevent ME (not enough if only implemented at one point of care); (iv) previous experiences with a CDSS (low rates of development of CDSSs are due to medication prescriptions being digitalized last in hospitals); (v) CDSS metrics (input data should be measured to control CDSS performance); and (vi) other barriers.ConclusionsIncluding facts and stakeholders’ values in problem definition and the scoping of health technologies is essential for the proper conduct of HTAs. Incorporating views from multiple stakeholders when scoping the assessment of health technologies brings additional values to literature findings, resulting in a more holistic evaluation. The lack of multistakeholder scoping can lead to inaccurate information and result in wrong decisions about if, when, and how to adopt a CDSS.

Published: December 2022

IntroductionThe use of Health Technology Assessment (HTA) in hospitals contributes to decision-making, professional training, greater interaction with technical to scientific knowledge, resource-saving, and partnerships. Hospitals are strategic for the field of clinical management and quality of care and are open to partnerships with national and international agencies and groups. Despite the hospital-based (HB)-HTA movement, the incipient application of HTA to the hospital decision-making process is related to incipient planning, and there is still much room for progress worldwide. The aim of this study was to analyze the uptake level of HB-HTA in diverse contexts.MethodsA scoping review was conducted according to the methodology of the Joanna Briggs Institute, whose data analysis model consisted of the combination of Donabedian’s structure, process, and outcome categories and the dimensions of the project Adopting Hospital Based Health Technology Assessment in European Union (AdHopHTA).ResultsWe identified 270 studies, and after removing duplicates and reading full texts, 36 references met the eligibility criteria. Thirty-six hospitals were identified, of which there were 24 largescale hospitals with extra bed capacity. Twenty-three hospitals were affiliated with universities. Canada stood out with five university hospitals, four of which with public funding. Half of the identified hospitals had HB-HTA units (18/36). Hospitals with full uptake level of HTA corresponded to 75 percent of the sample (27/36), and the remainder had partially uptake level of HTA, or 25 percent of the hospitals in the review (9/36). There were no hospitals with incipient uptake level of HTA.ConclusionsMeasuring the uptake level of HTA in hospitals contributed to understanding how their participation has occurred in the field of HB-HTA. This study revealed the importance of identifying factors such as sustainability, growth, and evolution of HB-HTA in countries with and without a tradition in this field.
PD09 Comparing Long-term Costs Associated With Intraocular Lens Selection And Nd:YAG Laser Capsulotomy In The UK: A Cost-Consequence Analysis
Authors: O’Boyle Derek , North James , Payton Emily 
Published: December 2022

IntroductionCataract surgery is the most frequently performed surgical procedure in the UK and posterior capsule opacification (PCO) is the most common complication post-surgery. Nd:YAG capsulotomy is the standard of care for treating PCO, although it bears a cost and is also associated with complications. The objective of this research was to estimate costs from a budget holders perspective associated with PCO related, post-cataract surgery resource use, comparing different single-piece intraocular lenses (IOLs) and utilizing results from a recently published audit of PCO incidence in the UK (n=601,084).MethodsThis research adapts the findings of the aforementioned audit to develop a cost-consequence analysis. The model is underpinned by the Nd:YAG rates of the included single-piece acrylic IOLs at 5 years. Nd:YAG related additional consultations and reported complications of the procedure were also included as variables of efficiency in the model. Estimates are presented from the perspective of a hospital setting in the UK, performing 3,000 cataract surgeries annually and extrapolated out to the broader cataract population (n=472,000). Costs were sourced from NHS Tariff documentation.ResultsAcrySof IQ was associated with lower Nd:YAG procedures and additional consultations at 5 years post-cataract surgery compared to all other single-piece monofocal acrylic lenses included in UK Audit Report. Assuming 3,000 cataract surgeries carried out annually, this translated into potential cost savings for the AcrySof IQ lens ranging from GBP 7,993 (EUR 9,379) (versus Eyecee One) to GBP 194,502 (EUR 228,243) (versus Akreos Adapt). Extrapolating to the broader population cataract patients in the UK would provide for a cost-saving estimates in the region of GBP 1.25 to GBP 30.6 million (EUR 1.47 to EUR 35.91 million).ConclusionsThis economic analysis highlights that the appropriate choice of IOL for cataract surgery, as a direct consequence of lower ND:YAG capsulotomy rates may translate into significant savings both for UK hospitals and the national healthcare system.

Published: December 2022

IntroductionWith the increasing use of health economic evaluation (HEE) in decision-making and health resource allocation and management policy design has seen an increase in HEE studies on screening programs in China l. In addition to the quantity of HEE, the quality may be of particular concern as it influences the reliability of HEE evidence adopted in policy formulation. This study sought to assess the reporting quality of HEE on screening programs over the last 20 years in China and identify potential predictors and relevant recommendations to improve the quality of study reporting.MethodsA search of HEE studies published in PubMed, Embase, CNKI and WANFANG from 2000 to 2021 was performed. Two reviewers independently extracted data and assessed the quality if reporting using the 24 item Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. The CHEERS score for each study was converted into standardized 0-1 point scale. General liner regression was used to identify predictors associated with the reporting quality.ResultsOne hundred and thirty-three studies met the inclusion criteria. The mean standardized score for the included studies was 0.56 (title), 0.64 (abstract), 0.74 (introduction), 0.58 (methods), 0.40 (results), 0.70 (discussion), and 0.54 (other section). The number and reporting quality of articles published each year showed an overall upward trend. A greater proportion of studies were published in Chinese journal (69.2%), modelling-based (54.9%), conducted by universities/research institutions (45.9%), focused on non-infectious disease (84.2%), using cost-effectiveness analysis method (50.4%), published in non-specialty journal (60.2%), and declaring the funding support (76.7%). Items related to study perspective, discount rate, measurement of effectiveness, currency and price, analytical methods, uncertainty, heterogeneity and conflicts were under-reported. Published year, journal type, first author affiliation and economic evaluation type predicted higher score in regression analyses (p<0.05).ConclusionsOverall, the quantity and quality of HEE on screening programs in China is improving, although there is a need to improve the use of on specific reporting items in the CHEERS criteria. The use of suitable evaluation guidelines will make the decision-making process more scientific.
PD13 Methodologies In Economic Evaluations Of Biomarkers – A Systematic Review
Authors: Neeser Kurt , Koller Linnea , Mueller Elvira 
Published: December 2022

IntroductionDiagnostic testing and patient monitoring are important to diagnose potential diseases and to evaluate treatment regimens. Since diagnosis and treatment monitoring have no intrinsic effects, an economic evaluation of biomarkers is inevitably linked to the resulting therapeutic interventions, which depend on both physicians’ decisions and diagnostic accuracy of the test (i.e., sensitivity, specificity). In this review we analyzed the methodology of economic studies evaluating the management of the five most relevant non-communicable diseases, that is, obesity, cancer, diabetes, cardiovascular and chronic respiratory diseases.MethodsA systematic search in Medline and the National Health Service Economic Evaluation Database (NHS EED) covering the last ten years served to identify health economic analyses of biomarkers used in diagnosing / monitoring. Findings were reviewed with respect to analytical method, reported outcomes and comparability.ResultsThe search yielded 680 abstracts in total out of which 280 full texts were reviewed and 77 sources included following predefined criteria. Most economic analyses (94%) evaluated the clinical outcome and costs of testing / monitoring in correlation to a corresponding intervention, 6 percent of the sources focused on the accuracy of the test or monitoring methods only. There were 61 studies that included an economic model; overall, 15 sources presented the outcome as cost per life year gained (CEA), 37 sources as cost per QALY gained (CUA), and 12 provided the outcome as both a CEA and CUA. In 16 analyses the outcome was presented in other economic terms as, for example, cost per additional case detected.ConclusionsDetermining the value of biomarkers requires consideration of the clinical consequences of a test result (incorrect treatment decisions, impact on morbidity, mortality, or quality of life) as well as the corresponding economic outcomes. Most of the identified studies considered at least one of these aspects. Results are presented in manifold ways but do not necessarily address decision makers’ needs. Thus, clear guidelines on economic evaluations of biomarkers are needed and should include broader health system views like affordability or the number of unnecessary interventions avoided.

Authors: Teixeira Leidy Anne , Toscas Fotini 
Published: December 2022

IntroductionThe Brazilian government has made efforts in systems to generate data from medical devices (MD). This work explores the main systems and data sources in the perspective of contributing as a source to generate real world data (RDW).MethodsDocument review of relevant national data sources for MD. In addition, a structured search was carried out in EMBASE using key descriptors for RWD applied to the regulatory context and to the management of health technologies, without date or language restrictions.ResultsEighteen primary federal government data sources for MD were identified. Not all sources are publicly accessible. Of the articles, the search returned 1,185 results, of which 29 titles were selected and 8 met the protocol’s objective. Included articles were from Europe, the United States and Canada. As in other countries, Brazil initially systematized DM administrative data to meet commercial and financial demands. With the evolution of health technology assessment methods, the use of RDW has become imperative to assess the value of MD to society. Common examples from these countries are implantable MD databases. Current challenges focus on data linkage and quality, in addition to standardized naming. The adoption of the Unique Device Identification (UDI) is one of the promising initiatives to facilitate traceability throughout the lifecycle proposed in the International Medical Device Regulators Forum (IMDRF) of which Brazil is a member. Among the systems, the following stand out: i) ConectSUS, which intends to provide access to health information centered on the patient, anywhere and at any time; ii) National implant registry that generates data on implanted prostheses and stents, surgical techniques used, the profile of patients and the health services involved.ConclusionsThis work showed the similarities between Brazil and other countries in the management of MD data throughout its life cycle, as well as mapped the national primary data sources for MD.

Authors: Pollock Richard F , Shergill Suki , Brennan Victoria K , Agirrezabal Ion 
Published: December 2022

IntroductionThere were an estimated 55,102 new cases of colorectal cancer (CRC) in Brazil in 2020, comprising 9.3 percent of all newly diagnosed cancers, and making it the third most common cancer in the Brazilian population. Up to half of all patients with CRC will develop liver metastases, and the prognosis for these patients is poor. The objective of the present analysis was to evaluate the cost-utility of selective internal radiation therapy (SIRT) using Y-90 resin microspheres versus best supportive care (BSC) in patients with unresectable, liver-dominant, chemotherapy-refractory metastatic CRC (mCRC).MethodsA three-state partitioned survival model was developed in Microsoft Excel to evaluate the cost-utility of SIRT using Y-90 resin microspheres versus BSC. Membership of the three model states of pre-progression, post-progression and death was governed by parametric models of Kaplan-Meier data from a retrospective, interventional study. Costs associated with SIRT using Y-90 resin microspheres, BSC, and adverse events were obtained from Brazilian sources and reported in 2021 United States dollars (USD). Future costs and effects were discounted at 5 percent. One-way and probabilistic sensitivity analyses (PSA) were performed. A willingness-to-pay threshold of USD 53,936 was used based on a 2017 review of Brazilian healthcare technology adoption.ResultsThe base case analysis showed that Y-90 resin microspheres would result in an increase of 0.76 QALYs versus BSC, increasing quality-adjusted life expectancy from 0.67 QALYs to 1.43 QALYs. The improvement in quality-adjusted life expectancy was accompanied by an increase in costs from USD 9,884 to USD 40,399 over the model time horizon, corresponding to an increase of USD 30,515, and yielding an incremental cost-utility ratio (ICUR) of USD 40,265 per QALY gained. PSA showed there was a 90.8 percent likelihood of cost-effectiveness at USD 53,936 per QALY gained.ConclusionsSIRT using Y-90 resin microspheres was cost-effective versus BSC in the treatment of unresectable, liver-dominant mCRC patients and should be considered for incorporation in the Brazilian Private Healthcare System.

Authors: Domingues Karime , Cobre Alexandre , Tonin Fernanda Stumpf , Pontarolo Roberto 
Published: December 2022

IntroductionWe aimed to map and synthesize the available evidence on neuron-specific biomarkers related to COVID-19.MethodsA systematic review and qualitative evidence mapping synthesis was performed (PROSPERO-CRD42021266995). Searches were conducted in PubMed and Scopus, and complemented by manual search (July 2021). We included observational studies of any design assessing neurological biomarkers in adult patients (>18 years; with or without neurological comorbidities) diagnosed with COVID-19. Methodological quality of nonrandomized studies (case-control, cohorts) was assessed using the Newcastle-Ottawa Scale.ResultsOverall, 14 studies (n=485 patients) conducted in Sweden (n=4 articles, 28.5%), Germany (n=3; 21.4%), USA (n=3; 21.4%), Canada, France, Italy and Norway (n=1 study each) were included. The most reported neurological symptoms (n=13 studies, 92.8%) were headache, confusion, general weakness, loss of smell/taste, cognitive impairments and behavioral changes. Prevalent neurological conditions included encephalopathies, neuropathies, myopathies, and delirium; most critical cases presented cerebrovascular events (n=4 studies, 28.5%). Hypertension, diabetes, obesity, dyslipidemia, and chronic lung disease were the most reported comorbidities. Eight different neuron-specific biomarkers were found in primary studies: neurofilament-light chain – NfL (n=10 studies; 71.4%), glial fibrillary acidic-protein – GFAp (n=5; 35.7%), tau protein (n=5; 35.7%), neurofilament-heavy chain – NfH, S100B protein, ubiquitin C-terminal hydrolase L1 - UCH-L1, neuron-specific enolase and beta protein-amyloid – Aβ (n=1 study each). These biomarkers were found both in cerebrospinal fluid and blood/plasma samples even without an evident cytokine storm. In patients with COVID-19, NfL and GFAp can act as sensitive indicators of neuroaxonal and astrocytic damages, respectively. Increased levels of NfL were significantly associated with severe COVID-19, unconsciousness and longer stay in the intensive care unit (p<0.05). Studies had an overall poor to moderate methodological quality.ConclusionsWe identified eight neuron-specific biomarkers that should be further studied as prognostic factors of COVID-19. These findings can also guide the development of targeted therapies against SARS-CoV-2. Additional well-designed clinical trials are needed to strengthen this evidence and help understand the mechanisms of neurological symptoms and sequelae after COVID-19 infection.

IntroductionPatients with chronic kidney disease (CKD) and COVID-19 are at high risk of adverse outcomes due to the presence of comorbidities. However, it is still unclear whether dialysis therapy is associated with a worse prognosis in patients infected with SARS-CoV-2. The objectives were to assess mortality and risk factors associated with a worse prognosis of these patients (e.g., age, sex, comorbidities, Intensive Care Admission [ICU] admission, and need for invasive mechanical ventilation [IMV]).MethodsAn observational, descriptive, retrospective study was conducted in the private healthcare maintenance organization (Unimed-BH) of Belo Horizonte and 33 surrounding cities in Brazil. We used data collected from the organization’s database. We included adult inpatients with CKD on previous dialysis therapy who tested positive for COVID-19, from February 2020 to June 2021.ResultsDuring the period, 16182 patients were admitted to Unimed-BH with a diagnosis of COVID-19. Of these, 333 (2%) had dialysis CKD. Male patients were 180 (54%), age ranged from 22.85 to 95.75 years and the mean was 60.91 years. Of the 333 patients, 109 (32.7%) were admitted to the ICU, and 56 (16.8%) required IMV. Among the 14 comorbidities analysed, the mean number of comorbidities was 6, with 93 (27.9%) dyslipidaemia, 74 (22%) diabetic, 270 (81%) hypertensive, 25 (7.5%) asthmatic, 42 (12.6%) with chronic pulmonary disease (CPD) and 122 (36.6%) with congestive heart failure (CHF). There were 66 (19.8%) deaths, 29 (43.9%) were male, the mean age was 60.8 years, and 23 patients (34.8%) were elderly (>60 years). Among the patients who died, 55 (83.3%) were in the ICU and 46 (69.7%) on IMV. The mean number of comorbidities was 9.27 being 16 (24.2%) dyslipidaemia, 44 (66.6%) diabetic, 60 (90.9%) hypertensive, 5 (7%) asthmatic, 10 (15%) with CPD and 32 (48.5%) with CHF.ConclusionsDialysis patients appear more susceptible to unfavourable outcomes than the general population. Our findings are similar to those reported in the world literature which is still scarce. It is important to conduct more studies on this population.
