ObjectiveTo estimate global surgical volume in 2012 and compare it with estimates from 2004.MethodsFor the 194 Member States of the World Health Organization, we searched PubMed for studies and contacted key informants for reports on surgical volumes between 2005 and 2012. We obtained data on population and total health expenditure per capita for 2012 and categorized Member States as very-low, low, middle and high expenditure. Data on caesarean delivery were obtained from validated statistical reports. For Member States without recorded surgical data, we estimated volumes by multiple imputation using data on total health expenditure. We estimated caesarean deliveries as a proportion of all surgery.FindingsWe identified 66 Member States reporting surgical data. We estimated that 312.9 million operations (95% confidence interval, CI: 266.2–359.5) took place in 2012, an increase from the 2004 estimate of 226.4 million operations. Only 6.3% (95% CI: 1.7–22.9) and 23.1% (95% CI: 14.8–36.7) of operations took place in very-low- and low-expenditure Member States representing 36.8% (2573 million people) and 34.2% (2393 million people) of the global population of 7001 million people, respectively. Caesarean deliveries comprised 29.6% (5.8/19.6 million operations; 95% CI: 9.7–91.7) of the total surgical volume in very-low-expenditure Member States, but only 2.7% (5.1/187.0 million operations; 95% CI: 2.2–3.4) in high-expenditure Member States.ConclusionSurgical volume is large and growing, with caesarean delivery comprising nearly a third of operations in most resource-poor settings. Nonetheless, there remains disparity in the provision of surgical services globally.
Key Points
Question
What are the differences in care and outcomes of patients with ST-segment elevation myocardial infarction among 3 vertical levels of hospitals in China?
Findings
In this cross-sectional study using data from the China Acute Myocardial Infarction Registry, which included 108 hospitals at the province, prefecture, and county levels, compared with patients in province-level hospitals, the rates of reperfusion therapy were lower among those in prefecture-level and county-level hospitals (69.4% vs 54.3% vs 45.8%). In-hospital mortality rates progressively increased among the 3 levels of hospitals, from 3.1% at the province level to 5.3% at the prefecture level to 10.2% at the county level.
Meaning
These findings suggest that more efforts should be made to address the gaps in care and outcomes of ST-segment elevation myocardial infarction for national quality improvement in China.
A concise one-pot three-component thioamination of 1,4-naphthoquinone with thiols and amines was developed to synthesize 2-amino-3-thio-1,4-naphthoquinones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
