Hospitalization costs in Portugal among people with obesity: results from a nationwide population-based cohort 2011 to 2021.

Background: Obesity has been extensively studied over the years, primarily focusing on the physiological aspects of the disease. However, the general burden of obesity mainly the financial implications and its influence on hospitalization and length of stay have only recently garnered attention in the literature, particularly in the case of Portugal. Aim: This study aimed to investigate the association between obesity and hospitalizations in the Portuguese adult population and compare the average costs of hospitalization among participants with and without obesity. Methods: At baseline, the analytic sample consisted of 10,102 participants aged ≥18 years from the Portuguese population-based Epidemiology of Chronic Diseases Cohort (EpiDoC). Participants were then followed for up to 10 years from 2011 to 2021 in three more waves of data collection. Body mass index was derived from self-reported weight and height, and instances of hospitalization were self-reported by the participants. The associated costs for each hospitalization episode were categorized according to national legislation and valued according to the pricing for Diagnosis Related Groups. Results: Obesity was associated with more hospitalizations (for example, Obesity class I vs. normal weight: OR = 1.33 [1.14-1.55]). However, when the presence of multimorbidity was considered, this association diminished. While longer hospital length of stay was observed in individuals with higher obesity categories, this difference did not reach statistical significance. On average, the total hospitalization costs per patient with obesity amounted to €200.4 per year. Conclusion: Obesity is as a risk factor for hospitalizations and potentially with higher length of stay hospitalizations, with this effect being partially mediated by the concurrent presence of multimorbidity. Consequently, obesity constitutes an additional burden on healthcare systems. This underscores the imperative of implementing cost-effective prevention programs aimed at addressing and managing this significant public health concern.

Drug effectiveness of 2nd and 3rd TNF inhibitors in psoriatic arthritis - relationship with the reason for withdrawal from the previous treatment.

OBJECTIVE: To investigate real-world retention and remission rates in PsA patients initiating a 2nd or 3rd TNFi and the association with reason for discontinuation from the previous TNFi-treatment. METHODS: Prospectively collected routine care data from 12 European registries were pooled. Retention rates (Kaplan-Meier estimation) and crude/LUNDEX-adjusted rates of Disease Activity Score 28 and Disease Activity index for PSoriatic Arthritis (DAS28 and DAPSA28) remission were calculated and compared with adjusted Cox regression analyses and Chi-squared test, respectively). RESULTS: We included 5233 (2nd TNFi) and 1906 (3rd TNFi) patients. Twelve-month retention rates for the 2nd and 3rd TNFi were 68% (95%CI: 67-70%) and 66% (64-68%), respectively. Patients who stopped the previous TNFi due to AE/LOE had 12-month retention rates of 66%/65% (2nd TNFi), and 65%/63% (3rd TNFi), respectively. Patients who stopped the previous TNFi due to LOE after less vs more than 24 weeks had 12-month retention rates of 54%/69% (2nd TNFi), and 58%/65% (3rd TNFi). Six-month crude/LUNDEX-adjusted DAS28 remission rates were 48%/35% and 38%/27%, and DAPSA28 remission rates were 19%/14% and 14%/10%, for the 2nd and 3rd TNFi. CONCLUSION: Two-thirds of patients remained on TNFi at 12months for both the 2nd and 3rd TNFi, while one-third and one-quarter of patients were in DAS28 remission after 6months on the 2nd and 3rd TNFi. While drug effectiveness was similar in patients who stopped the previous TNFi due to AE compared to overall LOE, drug effectiveness was better in patients who had stopped the previous TNF due to secondary LOE compared to primary LOE.

Anti-SSA Ro52 and anti-Ro60 autoantibodies: association with clinical phenotypes.

OBJECTIVES: Anti-SSA autoantibodies can be differentiated according to their antigenic target proteins as anti-Ro60 (60 kDa) or anti-Ro52 (52 kDa). Anti-SSA(Ro60) antibodies are clearly associated with connective tissue diseases (CTD), but the clinical significance of anti-SSA(Ro52) antibodies remains unclear. The aim of the present study was to analyse the disease phenotype of patients with anti-Ro52 and/or anti-Ro60 antibodies. METHODS: A multicentre, cross-sectional study was carried out of positive anti-Ro52 and/or Ro60 antibodies patients followed at 10 Rheumatology centres from January 2018 until December 2021. Patients were categorised into 3 groups: group 1 (Ro52+/Ro60-); group 2 (Ro52-/Ro60+); group 3 (Ro52+/Ro60+). Antinuclear antibodies were evaluated by indirect immunofluorescence assay and further screened for anti-extractable nuclear antigen (ENA) antibodies. Demographicsand clinical data were compared between the 3 groups, by patients' medical chart review. Univariate analysis was performed and subsequently logistic regression was used to identify intergroup differences and calculate the odds ratio with a 95% confidence interval (95% CI). RESULTS: We included 776 patients [female: 83.1%; median age: 59 (46-71) years]. Groups 1, 2, and 3 comprised 31.1%, 32.6%, and 36.3% of the patients, respectively. Anti-Ro52 antibody alone was more frequently associated with non-rheumatic diseases, older age, and men (p<0.05). Among patients with CTD, the diagnosis of systemic lupus erythematosus is 3 and 2 times more prevalent in groups 2 and 3, respectively, than in group 1 [OR 2.8 (95% CI 1.60, 4.97), p<0.001; OR 2.2 (95% CI 1.28, 3.86), p<0.01]. In group 2, the diagnosis of undifferentiated CTD is more frequent than in the other groups. Group 1 was more frequently associated with inflammatory myositis than group 2 [OR 0.09 (95% CI 0.01, 0.33), p<0.001] or group 3 [OR 0.08 (95% CI 0.01, 0.29), p<0.001]. Group 1 was also more frequently associated with arthritis (p<0.01), interstitial lung disease (p<0.01), and myositis (p<0.01). CONCLUSIONS: Anti-Ro52+ antibody alone is frequently found in patients with non-rheumatic diseases. In addition, anti-Ro52+ antibody is also prevalent in patients with CTD and associated with clinical phenotypes that are different from anti-Ro60+ antibody.

The impact of a Fracture Liaison Service after 3 years on secondary fracture prevention and mortality in a Portuguese tertiary center.

Despite the establishment of Fracture Liaison Services (FLS) worldwide, no study has evaluated their impact on the Portuguese population. Our work has shown that the implementation of an FLS is associated with a significant increase in OP treatment and a lower risk of secondary fracture. PURPOSE: Fracture Liaison Services (FLS) have been established worldwide, with positive effects on treatment, secondary fracture, mortality, and economic burden. However, no study has evaluated their impact on the Portuguese population. Therefore, we purposed to evaluate the effect of an FLS model in a Portuguese center on osteoporosis (OP) treatment, secondary fracture, and mortality rates, 3 years after a fragility fracture. METHODS: Patients over 50 years old, admitted with a fragility fracture, between January 2017 and December 2020, were included in this retrospective study. Patients evaluated after FLS implementation (2019-2020) were compared with those evaluated before (2017-2018) and followed for 36 months. Predictors of secondary fracture and mortality were assessed using a multivariate Cox regression model, adjusted to potential confounders. RESULTS: A total of 551 patients were included (346 before and 205 after FLS). The FLS significantly increased the rate of OP treatment, when compared with standard clinical practice (8.1% vs 77.6%). During follow-up, the secondary fracture rate was 14.7% and 7.3%, before and after FLS, respectively. FLS was associated with a lower risk of secondary fracture (HR 0.39, C.I. 0.16-0.92). Although we observed a lower mortality rate (25.1% vs 13.7%), FLS was not a significant predictor of survival. CONCLUSION: Implementing the FLS model in a Portuguese center has increased OP treatment and reduced the risk of secondary fracture. We believe that our work supports adopting FLS models in national programs.

Validation of the Portuguese Version of the Scleroderma Health Assessment Questionnaire.

The Health Assessment Questionnaire Disability Index (HAQ-DI) was completed with five visual analog scales to assess systemic sclerosis (SSc) called Scleroderma HAQ (SHAQ). We performed a validation of the European Portuguese version of SHAQ for patients with SSc. Patients with different forms of SSc from five Hospital Centers were invited. The reliability of the Portuguese SHAQ was evaluated by internal consistency and by test-retest reliability. Content validity was checked by two rheumatologists and by a panel of patients. Construct validity was assessed by structural validity and by known-groups hypothesis tests. Criterion validity was addressed with selected dimensions from the UCLA GIT 2.0, the SF-36v2, and the EuroQoL EQ-5D-5L. A total of 102 SSc patients agreed to participate, 31 of which answered to the retest. HAQ-DI demonstrated high internal consistency reliability (α = 0.866) and SHAQ also showed high test-retest reliability (ICC 0.61-0.95). We evidenced the unidimensionality of all VASs. HAQ-DI scores were worse in males, patients older than 65 years, and individuals with a diffuse form of SSc. Criterion validity was mainly evidenced through the correlation between the HAQ-DI and SF-36v2 physical summary measure (r = -0.688) and EQ-5D-5L index score (r = -0.723). Likewise, the SHAQ overall disease severity VAS was also correlated with SF-36v2 physical summary measure (r = -0.628). Mental score correlations were smaller. With the exception of the Raynaud's VAS, all the other VASs correlated well with similar clinical variables. This paper provides evidence to demonstrate how reliable and valid the European Portuguese version of SHAQ is, to be used in SSc patients to assess the clinical severity under the perspective of patients.

Second and third TNF inhibitors in European patients with axial spondyloarthritis: Effectiveness and impact of the reason for switching.

OBJECTIVE: To investigate real-world effectiveness of tumor necrosis factor inhibitors (TNFi) in patients with axial spondyloarthritis (axSpA) and the association with 1) treatment line (second and third TNFi-series) and 2) reason for withdrawal from the preceding TNFi (lack of efficacy (LOE) versus adverse events (AE)). METHODS: Prospectively collected routine care data from 12 European registries were pooled. Rates for 12-month drug retention and 6-month remission (Ankylosing Spondylitis Disease Activity Score C-reactive protein inactive disease (ASDAS-ID)) were assessed in second and third TNFi-series and stratified by withdrawal reason. RESULTS: We included 8254 s and 2939 third TNFi-series; 12-month drug retention rates were similar (71%). Six-month ASDAS-ID rates were higher for the second (23%) than third TNFi (16%). Twelve-month drug retention rates for patients withdrawing from the preceding TNFi due to AE versus LOE were similar for the second (68% and 67%) and third TNFi (both 68%), while for the second TNFi, rates were lower in primary than secondary non-responders (LOE < 26 versus ≥26 weeks) (58% versus 71%, p< 0.001). Six-month ASDAS-ID rates for the second TNFi were higher if the withdrawal reason was AE (27%) versus LOE (17%), p< 0.001, while similar for the third TNFi (19% versus 13%, p= 0.20). CONCLUSION: A similar proportion of axSpA patients remained on a second and third TNFi after one year, but with low remission rates for the third TNFi. Remission rates on the second TNFi (but not the third) were higher if the withdrawal reason from the preceding TNFi was AE versus LOE.

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

Osteoporosis-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. PURPOSE: This study aimed to estimate the costs of incident non-hip osteoporosis-related fractures among postmenopausal women living in Portugal from a payer perspective. METHODS: The 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. RESULTS: Each 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. CONCLUSIONS: This 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.

Creation and Validation of the European Portuguese Version of the Systemic Lupus Erythematous Quality of Life Questionnaire.

(1) Background: Patients with systemic lupus erythematous (SLE) experience profound effects on health-related quality of life (HRQoL) that cannot be explained by objective indicators of mortality and morbidity. This study aimed to adapt the SLE Quality of Life (SLEQoL) questionnaire to the European Portuguese population and to assess its reliability and validity for patients with SLE. (2) Methods: Two independent translators translated the original version of the SLEQoL questionnaire into Portuguese. A back-translated version was produced. The Portuguese version of the questionnaire was reviewed and tested for validity and reliability. Cronbach's alpha and the internal validity index were calculated to verify the internal reliability and validity of the content. Rheumatologists filled out the SLE Disease Activity Score (SLE-DAS) and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index SLICC/ACR-DI questionnaires. (3) Results: This study involved 180 patients, of which 93.8% were females. The results indicated very high internal consistency reliability (α = 0.949), low correlations between the SLEQoL and the SLE-DAS, a correlation between all SLEQoL dimensions and all SF-36 dimensions (except for "response to treatment" and "self-image"), and good correlation scores with both the EQ-5D-5L index and VAS. (4) Conclusion: The Portuguese version of the SLEQoL questionnaire is valid and reliable for the measurement of HRQoL in SLE patients.

Creation and Validation of a Portuguese Version of the UCLA Scleroderma Clinical Trial Consortium Gastrointestinal Tract Instrument.

(1) Background: The UCLA GIT 2.0 questionnaire has been recognized as a feasible and reliable instrument to assess gastrointestinal (GI) symptoms in systemic sclerosis (SSc) patients and their impact on quality of life. The aim of this study was to create and validate UCLA GIT 2.0 for Portuguese patients with SSc. (2) Methods: A multi-center study was conducted enrolling SSc patients. UCLA GIT 2.0 was validated in Portuguese using reliability (internal consistency, item -total correlation, and reproducibility) and validity (content, construct, and criterion) tests. Criterion tests included EQ-5D and SF-36v2. Social-demographic and clinical data were collected. (3) Results: 102 SSc patients were included, 82.4% of them female, and with a mean sample age of 57.0 ± 12.5 years old. The limited form of SSc was present in 62% of the patients and 56.9% had fewer than five years of disease duration. Almost 60% presented with SSc-GI involvement with a negative impact on quality of life. The means for SF-36v2 were 39.3 ± 10.3 in the physical component summary and 47.5 ± 12.1 in the mental component summary. Total GI score, reported as mild in 57.8% of the patients, was highly reliable (ICC = 0.912) and the Cronbach's alpha was 0.954. There was a high correlation between the total GI score and EQ-5D-5L and SF-36v2 scores. (4) Conclusion: The Portuguese version of UCLA GIT 2.0 showed good psychometric properties and can be used in research and clinical practice.
