  • Healthcare inequity among people with dementia in Gipuzkoa

    Open Access•Javier Mar, Mar J et al.•ARTICLE•Gaceta Sanitaria•2026

    To compare the use of healthcare resources among the Gipuzkoa population with and without dementia. A retrospective, cross-sectional cost study was conducted on the entire population over 60 years of age registered with the Basque Health Service. We measured the use of health services (hospital and primary care) and health needs as a function of the presence of dementia and neuropsychiatric symptoms, adjusting for age, sex and comorbidity. Genera…

  • El Exceso De Coste Social Directo De Los Síntomas Neuropsiquiátricos Relacionados Con La Demencia

    Open Access•Lore Zumeta-Olaskoaga, Javier Mar et al.•ARTICLE•Gaceta Sanitaria•2025

  • The impact of non-pharmaceutical interventions on Covid-19 transmission and its effect on life expectancy in two European regions

    Open Access•Carlo Delfin S Estadilla, Chiara Cicolani et al.•ARTICLE•BMC Public Health•2025

    Our model calibration approach provides a valuable tool for evaluating the effectiveness of interventions across multiple waves of an epidemic. By applying this method to COVID-19 dynamics, we have demonstrated the capacity to quantify the impact of non-pharmaceutical interventions (NPIs) on transmission rates. These findings offer practical insights into the effectiveness of NPIs in mitigating COVID-19 spread and contribute to the broader unders…

  • Stratified cost-utility analysis of total hip arthroplasty in displaced femoral neck fracture

    Open Access•Igor Larrañaga, Iñigo Etxebarria-Foronda et al.•ARTICLE•Gaceta Sanitaria•2022

    To conduct a stratified cost-utility analysis of total versus partial hip arthroplasty as a function of clinical subtype. All cases of this type of intervention were analysed between 2010 and 2016 in the Basque Health Service, gathering data on clinical outcomes and resource use to calculate the cost and utility in quality-adjusted life years (QALYs) at individual level. The statistical analysis included applying the propensity score to balance t…

  • Health care costs of breast, prostate, colorectal and lung cancer care by clinical stage and cost component

    Open Access•Oliver Ibarrondo, Garbiñe Lizeaga et al.•ARTICLE•Gaceta Sanitaria•2022

    To measure 3-year care costs of breast, prostate, colorectal and lung cancers disaggregated by site and clinical stage. A retrospective observational design was employed to investigate care costs of cases recorded in the Registry of the Basque Country between 2010 and 2015. Data gathered included TNM stage and demographic, clinical and resource use variables. Total costs per patient with stage IV disease were calculated by combining generalized l…

  • Changes in Social and Clinical Determinants of Covid-19 Outcomes Achieved by the Vaccination Program

    Open Access•Oliver Ibarrondo, Maíra Aguiar et al.•ARTICLE•International Journal of…•2022

    Despite the lifting of many control measures during the second half of 2021, restoring human mobility patterns, the situation could not be defined as syndemic, clinical determinants seeming to have more influence than social ones on COVID-19 outcomes, both before and after vaccination program implementation

  • Probabilistic cost-utility analysis and expected value of perfect information for the Oncotype multigenic test

    Open Access•Oliver Ibarrondo, Isabel Álvarez et al.•ARTICLE•Gaceta Sanitaria•2020

    To carry out a cost-utility analysis of the application of the Oncotype genomic test to inform the decision to use or not to use chemotherapy in the Basque Country (Spain). The cost-utility study was carried out using a discrete event simulation model representing the natural history of breast cancer. The decision of treatment with chemotherapy based on Oncotype was compared with the standard of treatment based on clinical-pathological criteria. …
