Reducing the work hours of medical interns does not improve their work efficiency report two recently published studies.

The authors attribute the findings to the fact that the trainees are still required to do the same amount of work but in less time.
Dr. Sanjay Desai, director of the Osler Medicine Training Program at Johns Hopkins University and lead study author of one study remarks that there has been a dramatic increase in ‘handoffs’ of patients from one staff to another. Handoffs are known to increase medical mistakes.
This work hour regulation also reduced the interactions between trainee and the teaching staff, which in turn reduced the knowledge gained by the trainees.
Though the studies have highlighted serious issues, there are certain limitations as the studies involved only small number of participants. According to Dr.Desai further research and data are required to find solutions to the issue.
