Article Synopsis
  • This text talks about a study that looks at how well deep learning algorithms (fancy computer programs) can do medical imaging tasks compared to expert doctors.
  • Researchers checked if the studies used good methods and if they were fair when comparing the algorithms to the doctors.
  • They found only 10 studies that really focused on how well these deep learning systems worked in real-life medical situations.

Objectives: To examine the association between financial performance as measured by operating margin (surplus/deficit as a proportion of turnover) and clinical outcomes in English National Health Service (NHS) trusts.

Setting: Longitudinal, observational study in 149 acute NHS trusts in England between the financial years 2011 and 2016.

Participants: Our analysis focused on outcomes at individual NHS Trust-level (composed of one or more acute hospitals).

Background: Pneumonia is responsible for approximately 230,000 deaths in Europe, annually. Comprehensive and comparable reports on pneumonia mortality trends across the European Union (EU) are lacking.

Methods: A temporal analysis of national mortality statistics to compare trends in pneumonia age-standardised death rates (ASDR) of EU countries between 2001 and 2014 was performed.

Background: The aviation industry pioneered formalised crew training in order to improve safety and reduce consequences of non-technical error. This formalised training has been successfully adapted and used to in the field of surgery to improve post-operative patient outcomes. The need to implement teamwork training as an integral part of a surgical programme is increasingly being recognised.

Objective: Since 2010, England has experienced relative constraints in public expenditure on healthcare (PEH) and social care (PES). We sought to determine whether these constraints have affected mortality rates.

Methods: We collected data on health and social care resources and finances for England from 2001 to 2014.

Design: Multivariate regression analysis.

Participants: OECD member states.

Objectives: To analyse how economic downturns affect child mortality both globally and among subgroups of countries of variable income levels.

Design: Retrospective observational study using economic data from the World Bank's Development Indicators and Global Development Finance (2013 edition). Child mortality data were sourced from the Institute for Health Metrics and Evaluation.

Objectives: To systematically categorise cancer research investment awarded to United Kingdom (UK) institutions in the period 2000-2013 and to estimate research investment relative to disease burden as measured by mortality, disability-adjusted life years (DALYs) and years lived with disability (YLDs).

Design: Systematic analysis of all open-access data.

Setting And Participants: Public and philanthropic funding to all UK cancer research institutions, 2000-2013.

Objective:  To examine whether a very large effect (VLE; defined as a relative risk of ≤0.2 or ≥5) in a randomised trial could be an empirical marker that subsequent trials are unnecessary.

Design:  Meta-epidemiological assessment of existing published data on randomised trials.

Background: The global economic crisis has been associated with increased unemployment and reduced public-sector expenditure on health care (PEH). We estimated the effects of changes in unemployment and PEH on cancer mortality, and identified how universal health coverage (UHC) affected these relationships.

Methods: For this longitudinal analysis, we obtained data from the World Bank and WHO (1990-2010).
