Diagnostic yield of colonoscopy for melena after nondiagnostic upper endoscopy is lower than previously reported

A study found the diagnostic yield of colonoscopy for melena after a nondiagnostic upper endoscopy to be 4.8 percent, significantly lower than previously reported. The rate of therapeutic intervention was also very low at 1.7 percent, suggesting that most procedures are diagnostic-only and can be performed on an elective basis.

Hospital readmission rates misleading

A new study by UCSF doctors suggests that publicly available overall readmission rates may overestimate unplanned readmissions by up to 25 percent. The team found that 'all cause' readmission rates do not distinguish between planned and unplanned surgeries, potentially leading to misinformation about hospital quality.
