Quantification of critical care medicine: An ICU survey.

BACKGROUND: The shortage in intensivist workforce has been long recognized but no solution has been identified. Meanwhile, fellowships in pulmonary and critical care medicine (PCCM) are expanding, other critical care medicine (CCM) programs are contracting. No explanation exists for this contradictory trend, although understanding contributory factors may lead to a solution for the shortage. The fundamental difference between PCCM and other CCM programs lies in the residency training of trainees. We tested the hypothesis that the nature of CCM practice determines its attractiveness to potential candidates. METHODS: A questionnaire-based survey was administered recording all daily activities in four different kinds of ICUs at two teaching hospitals one was public, and one was private. Activities were categorized into conventional CCM, respiratory, medical, and surgical interventions. RESULTS: The average daily census was 17.6 ± 6.6. Across two MICU, one trauma/surgical and one cardiothoracic ICU the average daily activity ranged from 152 to 203 of these CCM formed 27%-36%, respiratory 10%-13%, medical 43%-59%, and surgical 1%-15%. The combination of medical and respiratory interventions represented >50% of daily activities among all the ICUs. CONCLUSIONS: Quantitative description of ICU activities indicates that the majority of the ICU daily practice relies on medical and respiratory interventions, which may explain why PCCM remains popular.
