Epidemiological and clinical trends of visceral leishmaniasis in Portugal: retrospective analysis of cases diagnosed in public hospitals between 2010 and 2020

BackgroundLeishmania infantum is endemic in the Mediterranean region, presenting mostly as visceral leishmaniasis (VL). In Portugal, reporting of VL cases to public health authorities is mandatory, but significant underreporting is likely. This study aimed to describe the epidemiological and clinical aspects of the VL cases diagnosed in hospitals of the Portuguese National Health Service (NHS), between 2010 and 2020.MethodsCollaboration was requested to every hospital of the Portuguese NHS in Mainland Portugal. Cases were screened through a search of diagnostic discharge codes or, if not available, by a search of positive laboratory results for Leishmania infection. Sociodemographic and clinical data was retrieved from medical records. Simultaneously, the National Health authority was contacted to request access to data of notified cases of VL between 2010 and 2020. Descriptive, hypothesis testing and multiple binary logistic regression models were performed.ResultsA total of 221 VL cases were identified. A significant increase in estimated national incidence was seen in the years after 2016 (P = 0.030). VL was predominantly diagnosed in people living with HIV (PLWH) and in children (representing around 60% of the new cases), but the outcome was generally poorer in non-HIV patients with associated immunosuppression, with significantly lower rates of clinical improvement at 7 (P = 0.003) and 30 days (P = 0.008) after treatment. Atypical presentations, with gastrointestinal and/or respiratory involvement, were seen in 8.5% of VL cases. Hemophagocytic lymphohistiocytosis was diagnosed in 40.0% of children under 5 years of age. Only 49.7% of incident VL cases were reported. Simultaneous involvement of the skin was confirmed in 5.9% of patients.ConclusionsVL presents a continuing threat in Portugal, especially to PLWH and children, and an increasing threat to other immunosuppressed groups. Recent increases in incidence should be closely monitored to allow prompt interventions. Programs to control the disease should focus on providing tools for earlier diagnosis and on reducing underreporting and promoting an integrated surveillance of human and animal disease. These data should be combined with asymptomatic infection and vector information, following a One Health approach.Graphical

The Portuguese NHS 2024 reform: transformation through vertical integration

Vertical integration models aim for the integration of services from different levels of care (e.g., primary, and secondary care) with the objective of increasing coordination and continuity of care as well as improving efficiency, quality, and access outcomes. This paper provides a view of the Portuguese National Health Service (NHS) healthcare providers’ vertical integration, operationalized by the Portuguese NHS Executive Board during 2023 and 2024. This paper also aims to contribute to the discussion regarding the opportunities and constraints posed by public healthcare organizations vertical integration reforms. The Portuguese NHS operationalized the development and generalization of Local Health Units management model throughout the country. The same institutions are now responsible for both the primary care and the hospital care provided by public services in each geographic area, in an integrated manner. This 2024 reform also changed the NHS organic and organizational structures, opening paths to streamline the continuum of care. However, it will be important to ensure adequate monitoring and support, with the participation of healthcare services as well as community structures and other stakeholders, to promote an effective integration of care.

Cost-effectiveness of semaglutide 2.4 mg in chronic weight management in Portugal

BackgroundObesity and overweight are a significant public health concern. Subcutaneous semaglutide 2.4 mg injection is a glucagon-like peptide-1 (GLP-1) analogue approved by the European Medicines Agency as an adjunct to a reduced calorie diet and increased physical activity (diet and exercise, D&E) for the treatment obesity and overweight in the presence of at least one weight related comorbidity. This study aimed to assess the cost-effectiveness of semaglutide 2.4 mg in combination with D&E compared to D&E alone for the Portuguese setting.MethodsAnalysis were conducted using the Core Obesity Model (COM) version 18, a Markov state transition cohort model, to predict the health outcomes and costs of weight related complications based on changes in surrogate endpoints. Efficacy and safety data were sourced from the STEP trials (Body Mass Index, systolic blood pressure and glycemic status) from a cohort of adults aged on average 48 years with obesity (BMI ≥ 30 kg/m2) and ≥ 1 obesity-related comorbidities, over a time horizon of 40 years. Costs were estimated from the perspective of the Portuguese National Health Service. Sensitivity analyses were conducted to test the robustness of results across a range of assumptions.ResultsOn a patient level, Semaglutide 2.4 mg in addition to D&E compared to D&E alone, improved QALYs by 0.098 and yielded higher costs by 1,325 EUR over a 40-year time horizon, with an ICER of 13,459 EUR per QALY gained and 100% probability of cost-effectiveness at the given WTP. Semaglutide 2.4 mg remained cost-effective across all different scenarios and sensitivity analysis at a WTP of 20,000 EUR per QALY. Among the subpopulations examined, Semaglutide 2.4 mg yielded ICERs of 18,459 EUR for patients with BMI ≥ 30 kg/m2 and of 22,657 EUR for patients with BMI ≥ 35 kg/m2.ConclusionsSemaglutide 2.4 mg was cost-effective compared to D&E alone for patients with obesity (BMI ≥ 30 kg/m2) and weight related comorbidities in Portugal, over a 40-year time horizon.

Vertical Integration in Healthcare and Patient Satisfaction: An Exploratory Analysis of Portuguese Reforms

The performances of public corporate hospital units are being influenced by user behaviour, delayed service responses, and sustainability risks. Consequently, there is a need for these units to adopt a different approach to user care in order to attain overall success and mitigate discontent arising from delays and waiting lists. The faults within the public system are becoming increasingly apparent as a result of the growing emphasis on the transparency and authenticity of information. The reform of the Portuguese health system aims to enhance coordination among public, private, and social services. Additionally, it prioritises the integration of various levels of care within the Portuguese National Health Service, specifically by promoting the amalgamation of hospital business entities with primary care under single organisations known as Local Health Units. The objective of this study was to utilise the SWOT framework to examine the reform from the standpoint of citizens, as they are the focal point of the system and its long-term sustainability. The study revealed several benefits associated with the reform. However, it is crucial to address potential risks and opportunities in order to achieve the intended outcomes. If health managers and policy-makers effectively utilise the available opportunities, it can be inferred that there exists a favourable circumstance to implement a Local Health Unit model that seeks to integrate comprehensive care. This approach, by addressing the health issues of citizens, will create a larger scope for improvement and enhance citizen contentment. Moreover, it will ensure the long-term viability, ethical conduct, transparency, and genuineness of health outcomes.

Portuguese Global Medicines Access Index 2021: An Indicator to Measure Access to Hospital Medicines

ObjectivesAccess to innovative and effective medication is a citizen’s right. The main objectives of this study were to build an indicator to measure access to medicines within hospitals, the Global Medicines Access Index, and to identify the main existing barriers. MethodsCross-sectional study carried out in Portuguese National Health Service hospitals. A consensus methodology (expert panel of 7 members) was used to define which dimensions should be included in the index and the weighting that each should take. The panel identified 6 dimensions: access to innovative medicines, proximity distribution, shortages, access to medicines before financing decision, value-based healthcare, and access to medication depending on cost/funding. Data were collected through an electronic questionnaire (September 2021). ResultsThe response rate was 61.2%. Most hospitals used medicines with and without marketing authorization before the funding decision. Monitoring and generating evidence of new therapies results is still insufficient. The identified barriers were the administrative burden as the major barrier in purchasing medicines, with a relevant impact on shortages of medicines. Most respondents (87%) had a proximity distribution program, mainly implemented in the pandemic context, and the price/funding model was only identified by 10% as a barrier to access. The 2021 Global Medicines Access Index was 66%. Shortages and value-based use of medicines were the dimensions that had more influence in lowering the index value. ConclusionsThe new formula used to obtain a unique and multidimensional index for access to hospital medicines seems to be more sensitive and objective and will be used to monitor access.

Medical residency in Portugal: a cross-sectional study on the working conditions.

The current European crisis in human resources in health has opened the debate about working conditions and fair wages. This is the case with Resident doctors, which have faced challenges throughout Europe. In Portugal, they account for about a third of the doctors in the Portuguese National Health Service. No studies to date objectively demonstrate the working conditions and responsibilities undertaken. This study aims to quantify the residents' workload and working conditions. Observational, retrospective cross-sectional study which involved a survey on the clinical and training activity of Portuguese residents, actively working in September 2020. The survey was distributed through e-mail to residents' representatives and directly to those affiliated with the Independent Union of Portuguese Doctors. The descriptive analysis assessed current workload, and logistic regression models analyzed associations with geographical location and residency seniority. There were a total of 2,012 participants (19.6% of invited residents). Of the residents giving consultations, 85.3% do so with full autonomy. In the emergency department, 32.1% of the residents work 24 h shifts and 25.1% work shifts without a specialist doctor present. Regarding medical training, 40.8% invest over EUR 1,500 annually. Autonomy in consultations was associated with being a Family Medicine resident (OR 4.219, p < 0.001), being a senior resident (OR 5.143, p < 0.001), and working in the Center (OR 1.685, p = 0.009) and South regions (OR 2.172, p < 0.001). Seniority was also associated with investing over EUR 1,500 in training annually (OR 1.235, p = 0.021). Residents work far more than the contracted 40 h week, often on an unpaid basis. They present a high degree of autonomy in their practice, make a very significant personal and financial investment in medical training, with almost no time dedicated to studying during working hours. There is a need to provide better working conditions for health professionals, including residents, for the sake of the sustainability of health systems across Europe.

Prostate cancer treatment in Portugal: a nationwide analysis

Different treatment options exist for localized prostate cancer. Treatments performed in high-volume hospitals are associated with better results. Our objective was to describe time trends in prostate cancer treatments in Portugal and case volume per hospital. We used the national database of diagnosis-related group of the Portuguese Central Administration of the Health System to describe the number of radical prostatectomy (RP), brachytherapy (BT) and external radiotherapy (eRT) treatments performed in all National Health System hospitals. There was a rapid increase in the annual number of RP until 2006 and then a deceleration; BT treatments augmented significantly until 2011. The utilization of eRT also increased, surpassing RP after 2010. From the 46 hospitals performing RP, only eight had a case-volume > 50 treatments/year, and from the nine hospitals performing BT, only four accomplished > 15 treatments/year. In the 11 hospitals with eRT, nine performed > 50/year. Regarding RP, there was negative correlation between the hospital volume and length of stay (r = − 0.303; p = 0.041). In the Portuguese National Health Service there was a steep increase in the number of prostate cancer treatments, and there is an ample margin for concentration of RP and BT treatments, for improvement of the hospitals case volume.

O.4.4-3 Developing a bespoke undergraduate physical activity course for a Portuguese Medical School - the VANGUARD European Union Erasmus+ project

Abstract Purpose Embedding physical activity in the undergraduate curricula of frontline health professionals is one of the policies recommended by the World Health Organization and the European Commission to promote health-enhancing physical activity (HEPA). The VANGUARD project is supported by the European Union Erasmus+ Programme, and aims to embed physical activity in the undergraduate curricula of healthcare professionals in European countries. Within this project, this work aimed to describe the bespoke development of a physical activity and health course integrated into the undergraduate medical curriculum of a Portuguese Medical School. Project or policy description The School of Medicine and Biomedical Sciences of the University of Porto (ICBAS) was the invited Medical School to implement the VANGUARD project in Portugal - led by the Institute of Public Health of the University of Porto (ISPUP). An auscultation process with the undergraduate medical students was held to evaluate the importance of HEPA in their curriculum and assess the preferred operational characteristics of including a physical activity and health course in the Integrated Master’s degree in Medicine. A course proposal structure was then developed by the VANGUARD project Portuguese team from ISPUP, the Director of the Integrated Master’s degree in Medicine, and the Coordinator of the Medical Education Office of ICBAS, based on the students’ acceptability, the Medical School constraints, and VANGUARD project goals and resources. The course integrates 26 lessons, from physical activity technical terminology, epidemiology and guidelines, going through its relation with noncommunicable diseases (using #MovementForMovement resources), to Portuguese National Health Service brief intervention tools and community-based exercise programs - in a total of 20 hours of contact, including continuous evaluation and final case studies analysis. The course will be offered on an optional basis to 2nd-year medical students, on an online training platform, using a self-paced learning method. After embedding this course in ICBAS, it will be presented to the Council of Portuguese Medical Schools to be scaled up nationally. Conclusions Medical doctors and Medical Schools are key stakeholders in HEPA promotion, especially in the health sector. Successful implementation of HEPA policies requires tailored solutions to organizations and direct involvement of target groups in policy development.

Costs of incident non-hip osteoporosis-related fractures in postmenopausal women from a payer perspective

SummaryOsteoporosis-related fractures lead to high morbidity, mortality, and healthcare costs among post-menopausal women. This study showed that incident non-hip osteoporosis-related fractures are frequent among women aged 50 + in Portugal, leading to excessive healthcare costs of €74 million per year, in a conservative scenario.PurposeThis study aimed to estimate the costs of incident non-hip osteoporosis-related fractures among postmenopausal women living in Portugal from a payer perspective.MethodsThe study includes women ≥ 50 years old who participated in the baseline assessment (2011–2013) and the first follow-up wave (2013–2015) of the Epidemiology of Chronic Diseases cohort, a Portuguese community-based longitudinal prospective study (n = 2,762). Incident non-hip osteoporosis-related fractures were defined as any self-reported low impact non-hip fractures since baseline. Healthcare resource utilization during the year following fracture was obtained from an informal panel of experts. The amounts of resources used were multiplied by the national tariffs practiced in the National Health Service (NHS) to obtain the cost per patient in the year following a wrist, vertebral, or other site fracture, which was subsequently multiplied by the estimated annual number of incident fractures to obtain the total annual cost of incident non-hip osteoporosis-related fractures among postmenopausal women.ResultsEach year approximately 5,000 wrist, 3,500 vertebral, and 39,000 other-site osteoporosis-related fractures occur in women aged 50 + in Portugal. Healthcare costs per patient in the year following fracture vary from €2,709.52 for vertebral fractures to €3,096.35 for other fractures. Non-hip incident osteoporosis-related fractures among 50 + women cost approximately €74 million per year. Among all healthcare services, physiotherapy represents the bulk of costs.ConclusionsThis study pinpoints the relevance of preventing non-hip osteoporosis-related fractures, as these cost about €74 million per year in direct healthcare costs, a substantial impact on the budget of the Portuguese NHS.

Wilson's Disease: A Prevalence Study in a Portuguese Population.

Introduction Wilson's disease (WD) is a rare and underdiagnosed genetic disorder caused by anomalous tissue copper deposition, and for which epidemiological studies, specifically in Portugal, are scarce. Objectives This study aimed to evaluate the prevalence and incidence of WD and provide a description of its main clinical and laboratory features. Methods A retrospective study was carried out, with a search between 1995 and 2015, of all patients with a minimum follow-up of three months and birth confirmed in the northern region of Portugal, with an estimated population of 3,689,682 inhabitants. Database collection was based on the Portuguese National Health Service's clinical coding system, relying on clinical data from 13 northern Portuguese hospitals, liver biopsy histology results, and hospital prescription records. Clinical and biochemical correlations were statistically assessed using chi-square, Mann-Whitney U, Friedman, and Wilcoxon tests. Results Over the 20-year period, a prevalence of 1:37.000 and an incidence of one per million person-year was found. A total of 94 patients were analyzed, with a slight male predominance (53%), the majority with the onset of clinical manifestations in pediatric age (56%), with a median age at diagnosis of 16.6 years (interquartile range of 12.3-20,.8 years). Most patients presented with predominant liver disease (54.8%), with more than a third with cirrhosis; mixed hepatic and neurological manifestations in 17.9%; and mainly neurological symptoms in 10.7% of the patients. Neurological impairment was strongly associated with delayed development of the manifestations of the disease (p = 0.001) and also a higher detection of Kayser-Fleischer rings (p < 0.001), present in 27.0% of the patients. Regarding therapy, penicillamine has been the most widely used, with adverse reactions reported in 24.8%. At six and 12 months after initiation of therapy, a significant decrease in liver enzymes was found (ALT: p = 0.002; AST: p = 0.002, respectively), but no significant reduction was observed in urinary copper excretion. Conclusion This was one of the first studies regarding WD prevalence in a Portuguese population, contributing to a better understanding of the epidemiology, diagnosis, and management of WD in the northern region of Portugal. WD should be considered in any individual with unexplained hepatic or neurological manifestations, and initial symptoms may manifest at an early age, even in children less than five years old.A high percentage of patients were identified in the early stages of the disease by asymptomatic elevation of transaminases. Following copper chelation therapy, cytolysis markers appear to be more sensitive indicators of treatment response.

Implementation of the World Health Organization Age-Friendly Principles: A Case Study from Portugal.

Demographic ageing has emphasized the need to adapt current healthcare systems to the comorbidity profile of older adults. In 2004, the World Health Organization (WHO) developed the Age-Friendly Principles, but the approach to their implementation in the health systems still remains uncertain. This article intends to address this gap by assessing how the Principles are perceived and implemented in the Portuguese National Health Service (NHS), where this topic has recently been placed on the political agenda. A questionnaire survey was administered to primary care directors and hospital administrators, covering a total of 173 health units. Findings show that most respondents are unaware of the WHO Principles (71%) and do not identify the current organizational structure of care as a problem for the provision of care (80%). However, the implementation of the WHO Principles is lower than desired, especially regarding professional training and the management system (50% and 28% of the criteria are implemented, respectively). These criteria defined by the WHO are implemented in a reduced number of health units, as opposed to the physical environment where implementation is more widespread (64%). Accordingly, further dissemination and implementation support in the national territory are needed in order to improve the health outcomes of older adults and increase the performance of health units.

Coronary artery calcium score as a gatekeeper for further testing in patients with low probability of obstructive coronary artery disease: a cost-effectiveness analysis

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Current guidelines recommend not to routinely test patients with chest pain and low pretest probability (PTP &amp;lt;15%) of obstructive coronary artery disease (CAD) but envisage the use of risk modifiers such as coronary artery calcium score (CACS) to refine patient selection for testing. The aim of this study was to assess the cost-effectiveness (CE) of three different testing strategies in the approach to symptomatic patients with low PTP of obstructive CAD: A) not test; B) perform CACS, withholding testing if = 0 and proceeding to coronary CT angiography (CCTA) if &amp;gt; 0; and C) perform CCTA in all cases, without prior CACS. Methods We developed a CE model using data from a two-centre study of 1385 patients with non-acute chest pain and PTP &amp;lt;15% who underwent CACS immediately followed by CCTA. Key input data included the proportion of patients with obstructive CAD on CCTA (10.3%), the proportion with CACS=0 (57%), and the negative predictive value of CACS for obstructive CAD on CCTA (98.9%), which was considered the gold standard for this simulation. The CE of each strategy was defined as the cost per correct diagnosis. Direct costs were calculated using the price list from the Portuguese National Health Service. Indirect costs, including incidental findings, were estimated according to the literature. The cost attributable to a false-negative was set at 3 times the cost of a false-positive, as customary. Results Not testing would correctly classify 89.7% of cases, and would cost €121.433 per 1000 patients, due to the cost imputed to false negatives. Using CACS as a gatekeeper for CCTA would correctly diagnose 98.9% of cases, and cost €247.116 per 1000 patients. Employing CCTA as first-line test would correctly classify all patients, at a cost of €271.007 for 1000 diagnosed patients. Overall, the added cost for an additional correct diagnosis was €1.366 for CACS±CCTA strategy vs. no testing, and €2.172 for CCTA vs. CACS±CCTA. The corresponding cost-effectiveness thresholds (CET) were €943–€3.450 for men; and €1.527–€1.972 for women (Table 1). Conclusions Not testing patients with low PTP of obstructive CAD should be disfavoured unless the CET is below €1.366 per correct diagnosis. First-line CCTA yields the most correct diagnoses and is cost-effective above CET over €2.172 per additional correct diagnosis. Using CACS as a gatekeeper for further testing is cost-effective between these thresholds, which are wider for men than for women. These findings may inform decisions on testing, but the most suitable strategy will ultimately depend on the costs and amount of missed diagnoses stakeholders are willing to accept.

A Network-DEA model to evaluate the impact of quality and access on hospital performance.

The relationship between efficiency, quality, and access in healthcare is far from being well defined. In particular, there is no consensus on whether there is a trade-off between hospital performance and its social dimensions, such as the care appropriateness, safety, and access to proper health care. This study proposes a new approach based on the Network Data Envelopment Analysis (NDEA) to evaluate the existence of potential trade-offs between efficiency, quality, and access. The aim is to contribute for the heated debate around this topic with a novel approach. The suggested methodology combines a NDEA model with the weak disposability of outputs to handle with undesirable outputs related to the poor quality of care or the lack of access to appropriate and safe care. This combination results in a more realistic approach that has not yet been used to investigate this topic. We utilised data of the Portuguese National Health Service from 2016 to 2019, with four models and nineteen variables selected to quantify the efficiency, quality, and access to public hospital care in Portugal. A baseline efficiency score was calculated and compared with the performance scores obtained under two hypothetical scenarios to quantify the impact of each quality/access-related dimension on efficiency. The first scenario considers that each variable, individually, is at its best situation (for example, absence of septicaemia cases), and the second one, at its worst (e.g., all seen inpatients had a septicaemia case). The findings suggest that there might exist meaningful trade-offs between efficiency, quality, and access. Most variables exhibited a considerable and negative impact on the overall hospital efficiency. That is, we may expect a trade-off between efficiency and quality/access.

The Perception of quality and the performance in primary health Care of central Alentejo – Portugal

Quality and performance are current issues and a strategic priority for the Portuguese National Health Service. Currently, there is a lack of studies in primary health care (PHC) that assess the relationship between the quality and the level of performance of the Primary Health Care Teams. In Portugal, those teams are monitored through the Global Performance Index (GPI), which demonstrates, through a score, the procedures and results obtained by electronic records and the metrics defined for each indicator. This paper aims to analyze the relationship between the perception of the quality of health professionals (service culture; leadership; service strategy; infrastructure and external resources; information and knowledge; processes; service management; human resource planning and skills development, commitment; conditions, satisfaction, performance, and recognition; and results) in the different Primary Health Care teams of the PHC of Central Alentejo—Portugal, and the level of performance of the given teams (care performance; professional training; organizational quality; and services). Self-Perception of Quality Questionnaire for Primary Health Care (SPQQ4PHC) was used as an assessment tool. The population comprises 324 health professionals (Family Doctors, Nurses, and Medical Secretaries) distributed over 34 Primary Health Care Teams. When analyzing the global correlation of the variables in the SPQQ4PHC questionnaire with the GPI, it´s possible to confirm that twenty-one out of twenty-five correlates with the GPI. Thus, this study allowed us to conclude that, as health professionals perceive the quality of the variables increases, the GPI also increases, demonstrating that the dimensions of quality and performance are closely related.

Equity in the Access of Chinese Immigrants to Healthcare Services in Portugal.

International studies indicate that Chinese immigrants face barriers when trying to access healthcare in the host country. The aim of this study was to identify the barriers that Chinese immigrants face when accessing the Portuguese National Health Service. An observational, cross-sectional and quantitative study was carried out via a bilingual Portuguese/Mandarin self-completed paper questionnaire was applied. The study population consisted of individuals with Chinese nationality who were residing in mainland Portugal for at least one year and aged 18 years or over. A total of 304 individuals answered the questionnaire. The results show that 284 (93.4%) of the participants had already sought healthcare in Portugal. The participants identified language difficulties and health professionals' lack of knowledge of Chinese cultural habits as the most significant barriers to accessing healthcare in Portugal. Of a total of 165 participants who sought healthcare in China, confidence in treatment outcomes and health professionals' knowledge of Chinese cultural habits were the reasons given by 151 (91.5%) individuals. This study reveals the existence of linguistic and cultural barriers that can condition the access of the Chinese immigrant population to healthcare systems. Immigrants' access to healthcare can be promoted via policies that contribute to proficiency in the Portuguese language and medical literacy among the Chinese immigrant population. It can also be promoted by raising the awareness of health professionals to Chinese cultural habits.

Clinical Screening Prediction in the Portuguese National Health Service: Data Analysis, Machine Learning Models, Explainability and Meta-Evaluation

This paper presents an analysis of the calls made to the Portuguese National Health Contact Center (SNS24) during a three years period. The final goal was to develop a system to help nurse attendants select the appropriate clinical pathway (from 59 options) for each call. It examines several aspects of the calls distribution like age and gender of the user, date and time of the call and final referral, among others and presents comparative results for alternative classification models (SVM and CNN) and different data samples (three months, one and two years data models). For the task of selecting the appropriate pathway, the models, learned on the basis of the available data, achieved F1 values that range between 0.642 (3 months CNN model) and 0.783 (2 years CNN model), with SVM having a more stable performance (between 0.743 and 0.768 for the corresponding data samples). These results are discussed regarding error analysis and possibilities for explaining the system decisions. A final meta evaluation, based on a clinical expert overview, compares the different choices: the nurse attendants (reference ground truth), the expert and the automatic decisions (2 models), revealing a higher agreement between the ML models, followed by their agreement with the clinical expert, and minor agreement with the reference.

Integration of Refractive Services Provided by Optometrists into the Portuguese National Health Service

Introduction: Refractive error is a public health concern and even with relatively simple and cost-effective interventions it remains usually outside national health services (NHSs) not ensuring universal health coverage. This study aimed to generate evidence about the availability and accessibility of refractive services in Portugal and to present a plan for more efficient services. Methods: A situation analysis of the Portuguese existing refractive services within the NHS was conducted based on three health systems building blocks: service delivery access, service coverage, and workforce. A strengths, weaknesses, opportunities, and threats analysis was performed based on existent evidence to identify internal and external factors that can facilitate or hinder the integration of refractive services within the NHS. The number of eye care personnel to be integrated in the NHS was calculated considering the minimum ratios recommended by national and international technical reports. Results: Portugal has no specific services to address refractive errors within the NHS. Treatment of refractive error occurs at the level of eye care general services. There are 39 NHS eye care services, all hospital-centred and divided into three large groups, according to technical differentiation, the technology required, and workforce capacity. The workforce available is composed of ophthalmologists and orthoptists, together with nurses and other general paramedical assistants. 3 Portuguese municipalities have more than 1 NHS eye care service, 35 have 1 NHS eye care service, and 240 municipalities (in the mainland) have none. In 2021, 52% of the hospitals providing eye care services did not meet the recommended response times. Centralization of eye care services in urban areas, undifferentiated referral systems, and a shortage in the workforce per inhabitant was observed. Conclusions: Portuguese NHS has all the requirements to reorientate refractive care from the current hospital-based model to primary care. The country also has a trained and qualified workforce to address this condition. Evidence demonstrates that the provision of refractive services at primary care is efficient and effective and translates into an opportunity to identify other visual conditions.

C-sections and hospital characteristics: a long term analysis on low-risk deliveries

BackgroundPolicymakers aim to reduce C-section (CS) rates, due to well documented overtreatment. However, little is known about how hospital characteristics relate to their c-section rates on low-risk deliveries (CSR-LRD).MethodsCSR-LRD were computed using inpatient data from all Portuguese National Health Service hospitals (2002-2011). Linear and Fractional Response Models were estimated to quantify the relationship between CSR-LRD and a set of hospital characteristics: hospital size, type (exclusively obstetrics or not), Neonatal Intensive Care Unit (NICU) availability, obstetrician-to-obstetric bed ratio, and teaching status.ResultsCSR-LRD increased from 11.7% (2002) to 14.1% (2008), declining to 12.5% in 2011. While larger hospitals and hospitals with NICU had higher CSR-LRD rates, teaching status and obstetrician-to-obstetric bed ratio had no significant effect. Adjusted estimates, controlling for those four characteristics, indicate 91% of the variation in the CSR-LRD is left unexplained.ConclusionHospital characteristics do not explain variation in CSR-LRD rates. Further studies considering medical practice, financial incentives to hospitals and/or physicians, and patient education are needed.
