Background: Factors affecting time to lung cancer care may occur at multiple levels of influence. Mixed-methods reviews provide an approach for collectively synthesizing both quantitative and qualitative data. Prior reviews on timeliness of lung cancer care have included only either quantitative or qualitative data, been agnostic of the multilevel nature of influencing factors, or focused on a single factor such as gender or socioeconomic inequalities.

Background: The cost of medically attended RSV LRI (lower respiratory infection) is critical in determining the economic value of new RSV immunoprophylaxes. However, most studies have focused on intermittent RSV encounters, not the episode of care that captures the entirety of RSV illness.

Methods: We created age- and condition-specific cohorts of children under 5 years of age using MarketScan® data (2015-2019).

Article Synopsis
  • The study investigates the accuracy of claims data in identifying Respiratory Syncytial Virus (RSV) as a cause of lower respiratory tract infections (LRTIs) in children, finding that not all cases are properly coded or tested.
  • Researchers used claims data from 2011-2019, along with RSV positivity data, to model the relationship between LRTI rates and RSV, estimating that about 42% of RSV cases were recorded in claims.
  • The findings reveal that a significant percentage of LRTIs are attributed to RSV, but coding inconsistencies exist, prompting recommendations for data adjustments to improve accuracy in estimating RSV incidence.

Introduction: In administrative data, accurate timing of exposure relative to gestation is critical for determining the effect of potential teratogen exposure on pregnancy outcomes.

Objective: To develop an algorithm for identifying stillbirth episodes in the ICD-9-CM era using national Medicaid claims data (1999-2014).

Methods: Unique stillbirth episodes were identified from clusters of medical claims using a hierarchy that identified the encounter with the highest potential of including the actual stillbirth delivery and that delineated subsequent pregnancy episodes.

Background: Although respiratory syncytial virus (RSV) immunoprophylaxis is recommended for high-risk infants, the American Academy of Pediatrics (AAP) recommends against immunoprophylaxis in the same season following a breakthrough hospitalization due to limited risk for a second hospitalization. Evidence in support of this recommendation is limited. We estimated population-based re-infection rates from 2011-2019 in children <5 years since RSV risk remains relatively high in this age group.

Article Synopsis
  • Prenatal exposure to magnetic resonance imaging (MRI) with gadolinium-based contrast agents has raised concerns due to possible retention of gadolinium in fetal tissue and links to adverse pregnancy outcomes.
  • This study analyzed over 11 million Medicaid-covered pregnancies from 1999 to 2014 to assess the impact of such MRI exposures on fetal and neonatal death as well as neonatal intensive care unit (NICU) admissions.
  • Results showed similar rates of fetal or neonatal deaths (1.4%) in both groups (gadolinium and non-gadolinium MRI), with no significant difference in adjusted risks for death or NICU admission.

Article Synopsis
  • - This study highlights the ongoing concern over preventing prenatal exposure to teratogenic drugs, especially following the FDA's new regulations requiring drug manufacturers to implement strategies aimed at mitigating these risks after 2007.
  • - The research focused on analyzing data from pregnancies between 2006 and 2017 to assess how many exposures to known teratogenic drugs occurred, utilizing national insurance claims alongside established medical databases.
  • - The findings indicate a limited number of teratogenic drugs are actively monitored under these new risk evaluation strategies, and there's still uncertainty regarding the overall effectiveness of these programs in preventing prenatal exposure.

Article Synopsis
  • The GBD 2019 study systematically estimated the global cancer burden, providing data on incidence, mortality, and disability to help address cancer worldwide.
  • In 2019, an estimated 23.6 million new cancer cases and 10 million cancer deaths occurred globally, marking significant increases in rates since 2010, with cancer becoming a leading cause of both death and disability-adjusted life years (DALYs).
  • The impact of cancer varied across sociodemographic index (SDI) quintiles, with higher SDI areas seeing more new cases, while middle SDI areas experienced more deaths and DALYs, highlighting disparities in cancer burden.

Background: While evidence-based recommendations for the management pneumonia in under-5-year-olds at the community level with amoxicillin dispersible tablets (DT) were made by the World Health Organisation, initiatives to promote the integrated community case management (iCCM) of pneumonia through the proprietary and patent medicine vendors (PPMVs) have been poorly utilized in Nigeria, possibly due to low financial support and perceived benefit. This study provides costs, benefits and cost-effectiveness estimates and implications of promoting the iCCM through the PPMVs' education and support. The outcome of this study will help inform healthcare decisions in Nigeria.
