Hospital volume, calendar age, and short term outcomes in patients undergoing repair of abdominal aortic aneurysms: the Ontario experience, 1988-92.
To determine, for abdominal aortic aneurysm surgery, whether a previously reported relationship between hospital case volume and mortality rate was observed in Ontario hospitals and to assess the potential impact of age on the mortality rate for elective surgery. ⋯ The relationship between hospital volume and mortality or morbidity was very modest and observed only for elective surgery. Case fatality rates in patients with ruptured abdominal aortic aneurysms remained 10 times higher than for patients with unruptured abdominal aortic aneurysms, despite improvements in overall mortality in comparison to previously published data. More effective detection of aneurysms, including elective repair for those once considered "high risk" older patients, might further reduce the toll from ruptured aortic aneurysms.

Hand searching the Journal of Epidemiology and Community Health as part of th Cochrane Collaboration.
To identify randomised controlled trials (RCTs) published in the Journal of Epidemiology and Community Health and to explore the contribution of these to the evaluation of public health issues. ⋯ The journal has published many trials of importance to the development of evidence-based public health policy. Hand searching may need to be done independently by more than one person.
