RESUMO
Background: Women continue to have worse Coronary Artery Disease (CAD) outcomes than men. The causes of this discrepancy have yet to be fully elucidated. The main objective of this study is to detect gender discrepancies in the diagnosis and treatment of CAD. Methods: We used data analytics to risk stratify ~32,000 patients with CAD of the total 960,129 patients treated at the UCSF Medical Center over an 8 year period. We implemented a multidimensional data analytics framework to trace patients from admission through treatment to create a path of events. Events are any medications or noninvasive and invasive procedures. The time between events for a similar set of paths was calculated. Then, the average waiting time for each step of the treatment was calculated. Finally, we applied statistical analysis to determine differences in time between diagnosis and treatment steps for men and women. Results: There is a significant time difference from the first time of admission to diagnostic Cardiac Catheterization between genders (p-value = 0.000119), while the time difference from diagnostic Cardiac Catheterization to CABG is not statistically significant. Conclusion: Women had a significantly longer interval between their first physician encounter indicative of CAD and their first diagnostic cardiac catheterization compared to men. Avoiding this delay in diagnosis may provide more timely treatment and a better outcome for patients at risk. Finally, we conclude by discussing the impact of the study on improving patient care with early detection and managing individual patients at risk of rapid progression of CAD.
RESUMO
BACKGROUND: Cervical cancer is one of the most prevalent cancers in women caused by the human papillomavirus (HPV) that leads to a substantial disease burden for health systems. Prevention through vaccination can significantly reduce the prevalence of cervical cancer. The objective of this study is to evaluate the potential health and economic impacts of introducing two-dose bivalent (Cervarix) and quadrivalent (Gardasil) HPV vaccines in Bangladesh. METHODS: The study uses the Papillomavirus Rapid Interface for Modelling and Economics (PRIME) model to assess the cost-effectiveness of introducing HPV vaccination. The incremental cost-effectiveness ratios (ICERs) were estimated per disability-adjusted life years (DALYs) averted using the cost-effectiveness threshold (CET). The analyses were done from a health system perspective in terms of vaccine delivery routes. RESULTS: Introduction of bi-valent HPV vaccination was found highly cost-effective (ICERâ¯=â¯US$488/DALY) at Gavi (The Vaccine Alliance for Vaccines and Immunizations) negotiated prices. The value of ICERs were US$710, US$356 and US$397 per DALY averted for school-based, health facility-based, and outreach-based programs, respectively, which is consistent with the CET range (US$67 to US$854). However, bivalent and quadrivalent vaccines at listed prices were not found cost-effective, with ICERs of US$1405 and US$3250 per DALY averted, respectively, that exceeds the CETs values. CONCLUSIONS: Introducing a two-dose bi-valent HPV vaccination program is cost-effective in Bangladesh at Gavi negotiated prices. Vaccine price is the dominating parameter for the cost-effectiveness of bivalent and quadrivalent vaccines. Both vaccines are not cost-effective at listed prices in Bangladesh. The evaluation highlights that introducing the two-dose bivalent HPV vaccine at Gavi negotiated prices into a national immunization program in Bangladesh is economically viable to reduce the burden of cervical cancer.
