Early access to diagnosis and care is essential improve rates of survival from childhood cancer, particularly in low-income middle-income countries (LMICs). Composite indices are increasingly used compare country performance many health fields. We aimed develop a composite vulnerability index risk mortality associated with delays for cancer LMICs, the scores across countries.
The burden of congenital gastrointestinal (GI) anomalies is poorly understood. aim this systematic review to assess the global prevalence anomalies. We conducted a population-level birth gastroschisis, omphalocele, intestinal atresia, esophageal diaphragmatic hernia, Hirschsprung’s disease, and anorectal malformation. identified 103 studies from high middle-income countries. Gastroschisis was most reported condition. Studies geographic heterogeneity in malformation prevalence. disease have...
Objective . Birth prevalence estimates for major congenital gastrointestinal anomalies are sparse. This paper serves as an in-depth, a priori systematic review protocol our identifying and assessing studies reporting population-level birth anomalies. Methods We will use the Condition, Context, Population framework include of gastroschisis, omphalocele, intestinal esophageal atresia, Hirschsprung’s disease, diaphragmatic hernia, anorectal malformation in infants. assess bias using Joanna...
Neonatal deaths now account for more than two-thirds of all in the first year life and about half children under-five years. Sub-Saharan Africa accounts up to 41% total burden neonatal worldwide.

This retrospective was conducted TTH located Northern All neonates who died Intensive Care Unit (NICU) from 2013 2017 were included data obtained admission discharge books records....
Objective This study evaluates the priority given to surgical care for children within national health policies, strategies and plans (NHPSPs). Participants setting We reviewed NHPSPs available in WHO’s Country Planning Cycle Database. Countries with languages different from English, Spanish, French or Chinese were excluded.

The World Health Organization (WHO) recently launched the Global Initiative for Childhood Cancer (GICC), with goal of attaining at least 60% cancer survival children worldwide by year 2030. This study aims to describe global patterns childhood in 2019 help guide progress GICC target goal. In this ecological, cross-sectional study, we used 5-year net (2015-2019) data from a prior micro-modeling 197 countries and territories. Descriptive statistics were analyze overall each six tracer...

Lancet Commission on Global Surgery (LCoGS) proposed six indicators to guide the development national plans for improving monitoring access essential care. This study aimed characterise Somaliland health system according LCoGS provide recommendations next-step interventions. Methods In this cross-sectional nationwide study, WHO’s Surgical Assessment Tool–Hospital Walkthrough geographical mapping...

Sub-Saharan Africa experiences a disproportionate amount of pediatric surgical disease, with 80% children lacking access to timely, affordable, and safe care. This study aims characterize the burden disease outcomes conditions at Connaught Hospital, main referral hospital in Sierra Leone.
Over 1.7 billion children lack access to surgical care, mostly in low- and middle-income countries (LMICs), with substantial risks of catastrophic health expenditures (CHE) impoverishment. Increasing interest reducing out-of-pocket (OOP) as a tool reduce the rate poverty is growing. However, impact OOP on CHE remains poorly understood. The purpose this study was estimate global for pediatric care risk within between countries. Our goal 149 by modeling under various scale-up scenarios using...
