24 Hour Intensivist Coverage in the Medical Intensive Care Unit

Not Applicable

Completed

• Conditions: Critically Ill
• Interventions: Other: Nocturnal coverage

• Registration Number: NCT01434823
• Lead Sponsor: University of Pennsylvania

Brief Summary

The Hospital of the University of Pennsylvania's Medical ICU (MICU) is implementing a model of 24-hour intensivist staffing in September 2011. Funds and resources are not available to cover the entire year, only certain weeks will be covered. The investigators propose a randomized clinical trial to study the comparative effectiveness of nocturnal intensivist staffing in the HUP MICU on patient outcomes. The investigators will be collecting and analyzing patient data of all patients admitted to the MICU from September 12, 2011, to September 11, 2012.

Detailed Description

Available evidence suggests that intensivist management of critically ill patients improves patient outcome, suggesting that greater intensivist coverage might be better still. However, the effects of 24-hour intensivist coverage in ICUs are unknown. In FY11, leadership of the Hospital of the University of Pennsylvania (HUP) decided to roll-out a program for partial night-coverage of the Medical Intensive Care Unit (MICU). In light of this natural experiment, the investigators propose to study the comparative effectiveness of nocturnal intensivist staffing in the HUP Medical Intensive Care Unit. To do so, the investigators propose a randomized clinical trial comparing the presence of a nocturnal intensivist (in-hospital call) to a traditional model of nocturnal coverage with an intensivist available by phone (home call) in the HUP MICU, with respect to patient-centered outcomes and resource utilization. The investigators will randomly assign seven consecutive days (Monday through Sunday) at a time to in-hospital or home call, in two-week blocks. The investigators will conduct primary analyses of all patients admitted during night hours and secondary analyses of various subgroups of patients admitted during night hours as well as all patients admitted during any time of day during the study period from September, 2011, to June, 2011.

A sub-study designed to measure sleep and work duration, sleepiness, and attention in Daytime Intensivists (faculty and fellows) during their medical ICU rotation will be conducted. The variables measured will be compared between periods with and without in-house nocturnal intensivist staffing. All fellows and faculty who rotate through the medical ICU during this study period, Jan 2012 to Dec 2012 will be approached for possible recruitment.

Exclusion Criteria

• No patients who meet these inclusion criteria will be excluded from this study.
• For patients admitted more than once to the MICU during the same hospitalization, we will include only their first admission to the MICU for all analyses.
• Subjects under 18 are very rarely seen at the HUP MICU because they are generally treated at the Children's Hospital of Philadelphia.
• In the rare event that a subject under the age of 18 receives care in the MICU his or her data will be excluded from this study.

For the Intensivist Sleep and Work sub-study looking at sleep, work hours, and attention of Daytime Intensivists during their MICU rotations:

• All University of Pennsylvania faculty members and fellows from the Division of Pulmonary, Allergy and Critical Care will be eligible for inclusion in the study if they rotate through the MICU during the study period (January, 2012 through December, 2012).

Exclusion Criteria:

• There are no exclusion criteria for this sub-study.

Arm && Interventions

Group	Intervention	Description
Intervention - nocturnal coverage	Nocturnal coverage	Nocturnal coverage from intensivists will be randomized by week. The weeks that have intensivists in the MICU during the 7pm to 7am shift are the intervention weeks.

Primary Outcome Measures

Name	Time	Method
MICU Length of Stay	From time of admission in the MICU until time of discharge from the MICU - assessed up to 12 months	Time from ICU admission to discharge

Secondary Outcome Measures

Name	Time	Method
MICU Mortality	From time of admission to MICU until discharge from MICU - assessed up to 12 months	Mortality will be assessed during each patient's stay in the MICU from admission to discharge
Re-admission to the MICU Within 48 Hours	From time of discharge from MICU, to re-admission to the MICU - assessed up to 12 months	The investigators will measure, in hours, the time spent from discharge from the MICU until a patient is re-admitted to the MICU during the same hospital stay.
In-hospital Mortality	From time of admission to MICU to hospital discharge - assessed up to 12 months	Mortality will be assessed during each patient's stay in the hospital.
Discharge Home From Hospital	Assessed up to 12 months	Patients who were discharged from the hospital to their homes
Daytime Intensivist Daily Sleep Duration	Daily	This will be the primary outcome of the Intensivist Sleep and Work sub-study.
