This shift schedule supports a combination of 14-hr day shift , 15.5-hr cross-cover shift , and a 14-hr night shift for medical interns. The day shift and the cross-cover shift have the same start time (7:00AM). The night shift starts at around 10:00PM and ends at 12:00PM on the next day. This combination allows a day intern and night intern to be present at the same time in the morning rounds so they can discuss with the attending physicians the treatments for patients in the next 24-hr period. This plan requires 4 teams with each team rotating through the following shift sequence over a 4 day period: 1 day shift, 1 cross-cover shift, 1 night shift, one day off. The day off is actually a recovery day since the night shift does not end until 12:00PM.
