In 2006, a policy reform restructured the maternal and perinatal healthcare system, including closing smaller maternity units, to further improve care in Portugal. This study aimed to investigate the effects of the 2006 National Program of Maternal and Neonatal Health policy on spatial inequalities in access to care and consequently avoidable infant mortality. A thematic analysis of qualitative data including interviews and surveys and a quantitative spatial analysis using Geographic Information Systems was applied. Spatial inequalities were found which may lead to avoidable infant mortality. Inequalities exist in freedom of choice and autonomy in care, within a medicalized system. Changes in approach to and organization of care would further enhance equitable spatial access to care in maternal health and reduce avoidable infant mortality.

Background: Contact tracing (CT), the process of identifying and managing contacts of infected cases, is one public health and social measure that may reduce the spread of infectious diseases. While previous systematic reviews of CT exist, a comprehensive review of both the effectiveness and potential unintended consequences has not been undertaken to our knowledge. Understanding effective CT strategies could help governments and health authorities prepare effectively for emergency epidemic or pandemic situations. Objective: This study aims to systematically review the evidence on the effectiveness of CT across infectious diseases with epidemic or pandemic potential. Effectiveness is measured in terms of impacts on disease transmission, health care use, mortality, or unintended consequences. Methods: We searched 6 bibliographic databases (MEDLINE, Embase, Global Health, CINAHL Ultimate, Cochrane, and Scopus) between November 29 and December 3, 2024, with supplementary citation searching. We sought human studies comparing CT with interventions with no CT or other forms of CT, delivered in the community, in prespecified diseases of epidemic or pandemic potential. We included studies with any measure of disease transmission, related health care use, or unintended consequences of CT and prioritized studies with concurrent comparators. Screening, data extraction, and critical appraisal were performed in duplicate. Due to substantial heterogeneity, a narrative synthesis was performed. This review was informed by meetings with a patient and public involvement and engagement group. Results: After deduplication, a total of 12,816 titles and abstracts were screened, with 198 records assessed for eligibility at full text. Five additional studies were found through supplementary searching. Finally, 88 reports (of 86 studies) were included, of which 57 reports (of 55 studies) were prioritized. Two main routes of transmission were represented: respiratory (tuberculosis [TB], 15 studies; COVID-19, 5 studies) and blood-borne or sexually transmitted infections (STIs; 35 studies, of which 13 were in HIV, and 22 were bacterial or parasitic infections). No evidence was found on vector-borne, direct contact, or food- or water-borne routes of transmission. Evidence was highly heterogeneous, and more than half of the studies had notable methodological limitations. While there was no difference between CT and comparator interventions for most outcomes, there was some evidence of reductions in disease prevalence in TB and for provider-initiated CT to be superior to patient-led approaches in STIs. Only 2 studies reported measures of unintended consequences. Conclusions: We found inconsistent evidence for the effectiveness of CT, focused primarily on TB and on contrasts between provider-initiated CT and patient-led referral in STIs and HIV. High heterogeneity in study design precluded clear assertions regarding optimal strategies for CT, including with respect to relevant subgroups. Future work should consider generalizability of CT mechanisms across contexts, including by route of transmission and from the Global South, and a more thorough account of unintended consequences.

Background: Osteoporosis is a systemic skeletal disorder characterised by bone tissue deterioration, leading to reduced bone density and increased susceptibility to fractures. Osteoporosis screening is the process of identifying people with an increased risk of osteoporosis by using risk assessment tools or medical imaging. The National Institute for Health and Care Excellence recommends opportunistic risk assessment in women over 65 years or under 65 years with risk factors, though this guideline was last updated in 2017. Regular surveillance of the available evidence is warranted to gauge the volume and type of evidence published on key issues relating to population-based and targeted screening for osteoporosis. Objectives: To identify and review the volume and type of evidence on effectiveness and cost-effectiveness of population-based and targeted osteoporosis screening in women and to explore the consideration of health equity in the evidence base. Design and methods: Two information specialists developed the search strategy in MEDLINE (via Ovid) and translated it to 10 other databases. The title and abstract then full text of each record were screened by two independent reviewers. Disagreements were resolved through discussion. Records found through supplementary searches were single-screened as were reference lists of relevant guidelines identified. One reviewer completed data extraction of included studies, with a second reviewer checking the accuracy. Setting and participants: Included studies were required to be experimental designs, systematic reviews or cost-effectiveness studies with a standard care comparator. Populations of interest were women over 65 years and women below 65 years with osteoporosis risk factors. Interventions: Any population or targeted screening intervention involving any combination of risk assessment and dual energy X-ray absorptiometry scan designed to identify women with, or at risk for, osteoporosis. Main outcome measures: Outcomes related to osteoporosis prevention (osteoporotic fractures, all-cause fractures and mortality), possible screening harms and cost-effectiveness. Data sources: Searches were conducted in 11 databases and were supplemented by forward and backward citation searching. Review methods: Study characteristics and equity considerations were tabulated and narratively described. Results: The 19 included studies consisted of 3 randomised controlled trials with 9 sibling papers, 1 non-concurrent cohort study and 6 reviews. The primary studies generally included women 65 years old and older, with interventions involving several risk assessment and screening methods. Most reviews investigated the general population and included either bone mineral density measurement or clinical risk assessment for screening. Studies mainly reported fracture outcomes, with some quality-of-life and cost-effectiveness measures. Equity-relevant features analysed by studies included education, relationships, income and age. Limitations: Our inclusion criteria may have excluded some evidence discussed by other related reviews. Conclusions: Evidence on the effectiveness and cost-effectiveness of osteoporosis screening is limited, with reviews mainly drawing conclusions from the same few primary studies currently available. The evidence base lacks consideration of equity-related characteristics. Future work: High-quality trial evidence is required, particularly for targeted screening. Equity characteristics should be addressed in future work. Anticipated impact and dissemination: The review aims to identify gaps in the current evidence base for targeted and population osteoporosis screening to inform future research and healthcare policy-makers’ decisions.
