iCOMPARE is a randomized trial of two duty-hour regimens for Internal Medicine interns (PGY1 residents):


We are proposing to conduct a systematic, large-scale cluster randomized trial comparing the current duty-hour regimen (16 hour maximum) against a regimen with a longer shift length that includes a protected night sleep period (28 hour maximum). The goal of iCOMPARE is to provide evidence to help policy makers evaluate whether the duty hour standards that limit consecutive work hours for interns should be changed.

iCOMPARE is a two-year crossover study that will randomly assign approximately 40 ACGME-accredited Internal Medicine training programs to one of two duty-hour regimens:

16 is a duty-hour regimen that conforms to current ACGME requirements including a 16-hour maximum shift length
28PS is a new duty-hour regimen with a 28-hour maximum shift length that includes a mandated 4-hour period of protected sleep at night

Outcomes include measures of trainee sleep, trainee education, and patient safety. Planned substudies will include actigraphy and time-in-motion analyses conducted in a subset of the enrolled training programs.

The iCOMPARE team will recruit Internal Medicine training programs that meet certain pre-specified eligibility criteria for participation. Interested programs may check whether they appear to meet these eligibility criteria by visiting the iCOMPARE Request an Application page (link below). Interested programs that do not appear to meet those criteria may still complete the Request an Application form, providing as much information as possible, so that the iCOMPARE team can reassess eligibility. Eligiblity criteria are based on program size, hospital resident-to-bed ratio, and hospital patient volumes in diagnosis groups being measured.

Training programs that participate in the iCOMPARE study will agree to a number of important responsibilities, including:

Participating programs will be provided stipends to help offset iCOMPARE expenses. Trainees at participating programs will be provided small incentives for completion of surveys.

Programs that agree to participate in the Sleep Substudy or the Time-In-Motion Substudy will have additional responsibilities and will recieve additional financial support.


iCOMPARE is led by investigators from the University of Pennsylvania, Johns Hopkins University, and the Brigham and Women's Hospital/Harvard Medical School. The study is contingent upon receiving funding, with a decision expected during the summer of 2014.

The ACGME has approved waivers of the duty-hour standards for programs that participate in iCOMPARE.

iCOMPARE will select training programs to participate from a list of eligible programs that apply to join the study. Elgibility may be determined in two ways:

  1. Many programs have been pre-determined to be eligible based on data available from the ACGME and CMS
  2. Some programs that have not be pre-determined to be eligible may still request an eligibility assessment by providing more recent data to the iCOMPARE team

In both cases, interested programs should request an application by visiting the Request an Application page and supplying as much information as possible. Ideally, this request will be supplied by the Program Director.

The Request an Application page also contains information about which programs have been pre-determined to be eligible.
