One of the most relevant risk factors for suicide is the presence of previous attempts. The symptomatic profile of people who reattempt suicide deserves attention. Network analysis is a promising tool to study this field.

To analyze the symptomatic network of patients who have attempted suicide recently and compare networks of people with several attempts and people with just one at baseline.

1043 adult participants from the Spanish cohort “SURVIVE” were part of this study. Participants were classified into two groups: single attempt group (n = 390) and reattempt group (n = 653). Different network analyses were carried out to study the relationships between suicidal ideation, behavior, psychiatric symptoms, diagnoses, childhood trauma, and impulsivity. A general network and one for each subgroup were estimated.

People with several suicide attempts at baseline scored significantly higher across all clinical scales. The symptomatic networks were equivalent in both groups of patients (p > .05). Although there were no overall differences between the networks, some nodes were more relevant according to group belonging.

People with a history of previous attempts have greater psychiatric symptom severity but the relationships between risk factors show the same structure when compared with the single attempt group. All risk factors deserve attention regardless of the number of attempts, but assessments can be adjusted to better monitor the occurrence of reattempts.

Effective health intervention coverage decision-making hinges on understanding budget impact (BI). Despite progress in estimating cost-effectiveness thresholds, a standardized approach for defining BI, particularly high BI, remains elusive. Addressing this gap, our systematic review aims to identify existing BI thresholds and establish universally applicable BI categories, providing a much-needed framework for global health policy.

In our systematic review, we adhered to Cochrane methods and PRISMA reporting guidelines (PROSPERO protocol CRD42020221652). We included articles that detailed current BI or affordability thresholds used by national or regional healthcare systems, sourcing from PubMed, Embase, and International Network of Agencies for Health Technology Assessment (INAHTA) communications. To address variability across jurisdictions, we normalized BI/affordability thresholds to a fraction of each country’s total healthcare expenditure. This approach enabled us to categorize BI thresholds into four distinct levels (low, moderate, high, and very high) and apply these categories universally across countries.

We retrieved 1,592 records, identifying affordability thresholds and their underlying rationales in 12 countries: Argentina, Australia, England, Canada, Germany, France, Netherlands, USA, Taiwan, Ukraine, Scotland, and Singapore. Utilizing this data, we established four BI threshold levels relative to the total health budget: low (below 0.00005), moderate (0.00005 to <0.0001), high (0.0001 to <0.0002), and very high (>=0.0002). We then extrapolated these thresholds, along with their uncertainty ranges, to 174 countries, using 2022 World Bank data.

Our study provides a comprehensive overview of current global affordability thresholds and their implications for healthcare coverage and reimbursement. We found that explicit BI thresholds are predominantly established in high-income countries. Our findings offer critical, evidence-based guidance on affordability decision rules, applicable to health systems in 174 countries, thereby contributing significantly to the standardization and informed policymaking in global healthcare.

Environmental impact has been poorly addressed in health technology assessment (HTA) processes despite its potential role in promoting more sustainable health systems. Initiatives to incorporate this dimension into economic evaluations (EE) that support HTA are few and far between. We aim to identify the state of the art and challenges for incorporating environmental impact into the EE of HTA.

We conducted a scoping review to identify publications on the assessment of the environmental dimension of health technologies from different approaches: establishment of theoretical frameworks and methods; data search strategies; identification of parameters, designs, and indicators; as well as descriptions of practical applications in HTA (literature review, EE, or budget impact analysis). The literature search was conducted through PubMed. Selected studies should provide insights to incorporate environmental impact into the EE of HTA regardless of the technology or environmental aspect considered (carbon footprint, use of resources, waste generation, etc.).

From a total of 219 references initially identified, 22 publications meeting the selection criteria were found. The holistic approach is recognized as the most appropriate for incorporating the environmental dimension, through the evaluation of the entire life cycle of the technology, as well as the management of the disease and the use of resources throughout the care process. A large amount of information and accurate estimates about the impact of the technology are needed. Therefore, the first reported approaches have focused on particular aspects of the environmental impact of a health technology (mainly the carbon footprint).

The practical incorporation of the environmental dimension into the HTA is still very incipient. Foundations have begun to be established for its incorporation into economic evaluation. A consensus is required on the most appropriate methodologies and tools to collect the necessary data. It would also require a multidisciplinary approach and a framework for cooperation between all the stakeholders.

Suicide poses a severe public health challenge worldwide, impacting individuals, families, work, and society. The multifaceted nature of suicide demands a complex approach involving psychological, biological, social, cultural, and environmental factors. Recognizing suicide’s status as the leading external cause of death in Spain, prevention increasingly incorporates technology, specifically mobile and software applications.

A systematic review of the effectiveness and safety of mobile and software applications was conducted (MEDLINE, Embase, CINAHL, and PsycINFO databases). Outcome variables included: suicide; suicidal behavior; suicidal intent; suicidal ideation/thinking; self-perceived suicide risk; using/seeking mental health services; associated mental symptoms; mental health-related quality of life; satisfaction of the user and the health professional; adverse events related to the app, as defined in the included studies. Studies that do not include suicidal behavior, intention, or ideation were excluded. Where available data allowed, a meta-analysis was conducted for each outcome variable.

One systematic review and 13 randomized controlled trials (n=2,952) were analyzed. No significant differences were found in deaths by suicide or suicide attempts. At post-intervention, small but significant reductions were observed in suicidal ideation, hopelessness, depression, and worry, with anxiety reduction slightly above statistical significance. At follow-up (8 to 52 weeks), these variables also obtained significant results, except depression and suicidal ideation. Regarding safety, there was no significant difference in safety phone calls for participants with suicidal ideation.

The evidence on suicide prevention app effectiveness is of low quality, precluding conclusive findings. Attempt reduction is suggested at 21 percent, but the confidence interval includes a potential 60 percent increase. Evidence on suicide-related psychological variables (suicide ideation, depression, hopelessness, and anxiety) is of higher quality (low–moderate), but effects are small and clinically uncertain. Safety findings are uncertain, impacting risk/benefit balance.

Innovative public procurement (IPP) is a driver of innovation across sectors. IPP involves the strategic acquisition of cutting-edge technologies and solutions by public entities in collaboration with the private sector. This approach aims to leverage the potential of “omics” technologies, such as genomics and proteomics, within the public sector to advance healthcare solutions.

The IPP process comprises key phases such as needs identification, solicitation preparation, execution, evaluation and awarding, and impact and assessment. The methodology applied was based on the Rapid Assessment Tool for Omics Technologies developed by the Andalusian Agency for Health Technology Assessment, accompanied by clinical validity reports from the impact and evaluation phase of the Technical Office for IPP of Andalusia. The aim was to assess the clinical validation results of two omics technologies, that is, two diagnostic tests. A systematic review was performed to identify existing evidence. We also addressed the challenges associated with implementing the Rapid Assessment Tool in the IPP process.

Systematic reviews identifying evidence on the clinical validity and utility of omics technologies provided a foundation for the subsequent evaluation of two technologies in development, once the clinical trials had finished. An analysis of scientific evidence, together with the compilation of information provided by industry, was conducted through a questionnaire and clinical data derived from the company’s studies. The analysis of clinical and diagnostic validity was not conclusive. We delivered the final assessment report to support decision-making in the public health system of Andalusia.

Both assessed technologies presented a high degree of innovation, but different challenges and issues were identified during the application of the Rapid Assessment Tool for Omics Technologies. Further improvement in IPP procedures for innovative technologies in Andalusia, including integration of our methodological approach at the start the IPP process, could facilitate the acquisition of cutting-edge technologies in collaboration with public entities.

Preadoption assessments are the most frequent type of evaluation conducted by the Spanish Network of Agencies for Health Technology Assessment and Services of the National Health System (RedETS). RedETS aimed to develop a framework to utilize real-world data (RWD) to better adjust its assessments to the Spanish population’s context and provide live assessments throughout the lifecycle of health technologies.

A working group within RedETS was set up, which held several meetings to define the primary uses of RWD in the short term. Next, a manual review was conducted on national and international initiatives that provided guidance on the use of RWD in HTA. Common pathways for utilizing RWD in HTA were identified. The working group agreed to outline and explain the key overarching steps and provide general guidelines for working with RWD, developing as illustration a use case for an interventional technology. The Big Data project of Aragon (BIGAN) was chosen as the data source for the use case.

We formulated a case for leveraging RWD in the assessment of implantable cardiac defibrillators (ICDs) for the prevention of sudden cardiac death (SCD). Based on this scenario, we developed a methodological framework outlining a workflow consistent with RedETS practices. RWD complemented the usual process of systematic review of a technology. Crucial steps comprised the definition of data requirements through a data model specification, an exploratory data analysis, and the construction of a decision model. We presented solutions for dealing with unavailable data on essential variables and unstructured records. We discussed the main limitations to account for when working with RWD.

The task ahead holds great hope but requires overcoming some challenges to fully deploy RWD-driven methods. This entails fostering collaboration with health authorities and designated data holders to address data access challenges. In the short term, it is essential to include data scientists in assessment teams and provide appropriate capacity-building to encompass RWD tools and modeling techniques.

Health technology assessment (HTA) applications in low- and middle-income countries face limited technical capacities. The Institute for Clinical Effectiveness and Health Policy (IECS) is a key player in strengthening HTA expertise in the region and offers a variety of courses. Over 200 students from across Latin America have undertaken our introductory course on HTA and economic evaluation in the last four years.

The IECS provides a nine-week introductory online course focused on the fundamentals of HTA and economic evaluation. The course is designed for healthcare professionals (doctors, administrators, auditors, nurses, pharmacists, lawyers, etc.). The materials are available in Spanish and Portuguese on a virtual campus with asynchronous activities. Students are guided by instructors through an exchange forum. This study aimed to showcase the outcomes of this HTA course. Our analysis encompassed quantitative and qualitative data from a survey administered to nine student cohorts over the last four years. The surveys featured eight question categories covering materials, activities, quizzes, course dynamics, forum usage, tutoring, and satisfaction.

A total of 234 students from Latin America were enrolled in the course. More than half came from Argentina (68%). Of the initial enrollees, 212 (91%) started the course and 192 (91%) of them passed. The satisfaction survey was completed by 168 students. Ninety-six percent of students were satisfied or very satisfied with the course overall, and the same percentage would recommend it to a colleague. Eighty-six percent felt that they could adequately follow the course, and 40 percent of students dedicating an average of two to four hours per week to the course.

Having accessible and feasible training opportunities in the region is important. The IECS HTA and economic course enhances HTA expertise in Latin America, as evidenced by its high rates of enrolment, completion, and satisfaction, with over 90 percent of participants recommending it. This underscores its effectiveness in reinforcing health decision-making knowledge in Latin America and contributing to the advancement of health policy.

Cardiac rehabilitation (CR) with physical exercise is crucial for the secondary prevention of myocardial infarction and heart failure. However, according to published studies there are differences in access to hospital-based CR depending on sex, age, ethnicity, and geographical region. An alternative is CR in non-hospital settings such as primary care, the patient’s home, or another place by means of telerehabilitation.

We conducted a systematic review of full economic evaluations where non-hospital CR was compared with hospital CR in patients with ischemic heart disease or heart failure. Other eligibility criteria were model-based or clinical trial-based evaluations; studies reporting quality-adjusted life-years, years gained, or other clinical outcomes relevant to CR; and studies published in English or Spanish. Searches were conducted in June 2023 in various literature databases, including MEDLINE, Embase, CINAHL, Web of Science, INAHTA, PEDro, the Cost-Effectiveness Analysis Registry, and others. Study selection, data extraction, quality assessment, and evidence synthesis were conducted by one economist and checked by a second reviewer.

Nine studies were selected from the 673 references identified. Another study was identified through previous systematic reviews. Ten randomized clinical trials were included in the review. None of the studies found differences in effectiveness between hospital CR and non-hospital CR. Two studies found that non-hospital CR was less costly than hospital CR, whereas the remainder did not find any differences in costs between the two groups or were unable to demonstrate the statistical significance of any differences observed. The best conducted studies concluded that non-hospital CR was as effective as and less costly than hospital CR.

Non-hospital CR was as cost effective as hospital CR for low- to-moderate risk patients. Based on the evidence, CR can be recommended in non-hospital settings. However, any form of CR should be evaluated after implementation because its complexity limits the generalizability of results across regions.

Fibromyalgia, a musculoskeletal ailment of unknown origin, profoundly affects quality of life. Emerging bioelectrical stimulation techniques, including transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), and pulsed low-frequency magnetic field stimulation (PEMF), show promise in short-term pain alleviation. This study aimed to rigorously evaluate the effectiveness and safety of these techniques in treating fibromyalgia.

A systematic review (SR) of available literature on the effectiveness and safety of bioelectrical stimulation techniques was carried out according to the Cochrane Collaboration methodology and PRISMA reporting guideline. Evaluated studies included SRs (with or without meta-analyses) and randomized controlled trials (RCTs) published after the SRs. SRs were appraised with the AMSTAR-2 tool and RCTs were assessed with version two of the Cochrane Collaboration risk-of-bias tool for randomized trials. The findings were synthesized narratively. In the absence of SRs with meta-analyses for specific techniques, we conducted a meta-analysis for each available outcome measure, including pain, fatigue, symptom severity, quality of life, anxiety, and depression.

Seven SRs incorporating 35 RCTs were included. Two SRs evaluated TMS effectiveness, while five focused on tDCS. Additionally, 17 RCTs were included: two on repetitive TMS, six on tDCS, and eight on PEMF (three assessing targeted PEMF). General confidence in the SR results varied, with most having critically low confidence. Three additional RCTs were rated as low risk of bias, seven were rated as unclear risk of bias, and the remaining seven were rated as high risk of bias. A meta-analysis covered additional RCTs on PEMF and assessed pain intensity, symptom severity, general health-related quality of life, and fibromyalgia-related quality of life.

Overall, the results suggest that repetitive TMS, tDCS, and PEMF could improve pain and quality of life in patients with fibromyalgia. It is, however, necessary to conduct high quality studies to demonstrate the clinical relevance of these effects. While the techniques evaluated appear to be safe, mild adverse effects involving the area of stimulation may occur.

The evidence synthesis developed to inform decision-making on the use of cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) for pediatric peritoneal carcinomatosis showed that currently available evidence is of very low quality. As new evidence could arise within the following months, we adopted a rigorous living evidence synthesis (LES) approach to provide a timely update and favor decision-making based on actual evidence.

This LES started with a baseline synthesis about the effects of CRS and HIPEC on pediatric peritoneal carcinomatosis. On 31 August 2023, we set up the evidence monitoring for up to 12 months. Following the Living Evidence to Inform Health Decisions (LE-IHD) framework, we planned and developed the evidence monitoring, supported by technological enablers. We searched for ongoing studies in trial registries every three months. New eligible studies were assessed following a systematic and reproducible process to decide on their incorporation in the evidence summary. This process was periodically reviewed to determine the continuation/withdrawal of the living mode.

The baseline synthesis identified one systematic review suggesting that CRS and HIPEC could increase overall survival in pediatric peritoneal carcinomatosis (very low-quality evidence), but no comparative data could be obtained against usual care. To date, the evidence monitoring has not identified new relevant studies on the impact of CRS and HIPEC in overall and disease-free survival, morbidity, or quality of life in pediatric peritoneal carcinomatosis. At the time of the conference, we will report on nine months of monitoring and regular updates including key messages on any changes in the evidence synthesis conclusions.

For HTA reports based on very low-quality evidence (uncertain results), the LE approach allows for timely updating of conclusions, adding value in decision-making. The LE-IHD framework facilitates HTA developers’ tasks for planning and conducting LE synthesis to inform health decisions.

Epilepsy affects approximately 10.5 million individuals under the age of 15 years worldwide. In Spain, 3.7 per 1,000 inhabitants aged 6 to 14 years have epilepsy, making it the third most common neurological emergency. Drug resistance is observed in eight to 33 percent of cases. Responsive neurostimulation (RNS) systems could improve seizure control in pediatric patients who are not eligible for brain surgery.

We systematically searched for articles published up to September 2022 in the following bibliographic databases: MEDLINE, Embase, Web of Science, and CINAHL. We included primary experimental and observational studies as well as case series studies addressing the safety, efficacy, and cost effectiveness of RNS in the treatment of drug-resistant pediatric epilepsy.

Two systematic reviews of prospective and retrospective case series studies and four primary experimental studies were identified. The case series studies found that a large proportion of pediatric patients responded to RNS, with a reduction of between 50 and 75 percent in the frequency of seizures. The intensity and duration of seizures also decreased after using RNS. Adverse effects of the RNS implantation process were related to infections, erythema, and hematomas. Only one study (n=17) reported moderate adverse effects related to stimulation (dysesthetic pain in the upper and lower right limb), but there were no serious reactions leading to RNS discontinuation.

Randomized controlled trials in pediatric drug-resistant populations ineligible for brain surgery with adequate sample sizes are needed to determine the effectiveness of RNS in terms of seizure frequency, duration, and intensity. No cost-effectiveness studies have been conducted on RNS in this cohort.

In collaboration with a European Reference Network for rare diseases, we aimed to identify red flags for the diagnosis of rare and complex connective tissue and musculoskeletal diseases (rCTDs). Some indicators, presented as red flags, might raise clinicians’ awareness about the presence of rCTDs. Their identification is critical in primary care, where they are most likely to be first observed.

Firstly, we conducted a scoping review to identify red flags already published in the scientific literature. We included studies about people with rCTDs that described red flags, warning signs, alarm symptoms, and pathognomonic signs identifiable in a primary care setting. Then, we conducted a systematic review of evidence pointing out which signs and symptoms should arouse suspicion specifically for IgG4-related disease. We included studies providing estimates of diagnostic precision or prevalence of signs and symptoms, and we assessed their quality and applicability to the review question. We conducted systematic searches in major medical databases and manual searches in rare disease resources.

For the scoping review, 49 studies out of 1,656 records met the inclusion criteria. Two reported red flags for autoimmune diseases altogether, and 14 described red flags for systemic sclerosis. For the systematic review, seven studies out of 4,477 records met the criteria, comprising five diagnostic precision studies and two large case series. These were generally rated as having a high risk of bias and were included as indirect evidence. We identified 32 potential IgG4-related disease red flags, 10 related to clinical history findings and basic signs or symptoms, and eight belonging to common laboratory findings and basic imaging techniques.

Red flags for rCTDs have generally been established through expert consensus and lack valid indicators for diagnosis, such as sensitivity, specificity, or predictive values. They frequently overlap among different rCTDs. Potential red flags are prone to change as further evidence emerges. This shows the need to collaborate with reference networks to address rare diseases where the evidence is still scarce.
