Intensivist-to-patient ratios in ICUs: is there a number?

Area of Science:

• Critical Care Medicine
• Healthcare Management
• Physician Workforce Studies

Background:

• Increasing demand for critical care services has outpaced the supply of intensive care unit (ICU) physicians.
• Growing pressure exists to increase patient loads per intensivist due to physician shortages.
• Limited data and guidelines were available regarding appropriate intensivist-to-patient ratios.

Purpose of the Study:

• To review existing data to inform decisions on intensivist staffing levels.
• To summarize the recommendations from the Society of Critical Care Medicine (SCCM) Taskforce on intensivist staffing.

Main Methods:

• Review of published literature addressing intensivist staffing and patient ratios.
• Analysis of the SCCM Taskforce's published guidelines and recommendations.

Main Results:

• The SCCM formed a task force in 2013, publishing guidelines for hospital intensivist staffing.
• This review synthesizes data to support these staffing decisions.
• Specific maximum intensivist-to-patient ratios are challenging due to patient complexity.

Conclusions:

• Staffing levels significantly impact patient care, staff well-being, and workforce stability.
• Indicators of inappropriate staffing include worsening patient outcomes, compromised teaching, and workforce issues.
• Adjustments to intensivist staffing are necessary when predicted daily workload exceeds available work hours.
