Why fearing shortage in Europe? In the present time :
The trained ICU physicians are getting older There is a reduction in the working time
48 h a week No clinical activity after on night duty during a
11 h period In the future :
Reduction in the number of physicians Reluctance to choose CCM as a specialty :
To much work including nights duty Medico-legal issue

Critical care services and personnel : recommendations based on a system of categorization into two levels of careAmerican College of Critical Care Medicine of the SCCM. Crit Care Med 1999, 27 : 422
Medical staff organisation A distinct medical staff The team is organized and led by an intensivist Patient management is directed by an
attending physician who : Has clinical management responsibility Is board certified in CCM Sees the patients as often as required but at
least twice daily Participation in the institution’s bioethical
committee
![Page 28: How to match supply and demand?](https://reader036.fdocuments.in/reader036/viewer/2022081506/568130e5550346895d96fd27/html5/thumbnails/28.jpg)
Physician availability 24-hr in-house coverage
Non tertiary center : At least one physician who can manage emergencies. If this requirement is fulfilled by senior residents, an attending physician fully credentialed in CCM must be on call and available within 30 mins.
Tertiary center : Critical care physician is appropriately credentialed to provide dedicated care to the critical care unit patients: If this requirement is fulfilled by critical care fellows, a critical care staff physician must be on call and available within 30 mins.

The French model
Maximum working time per week : 48 h, including on nights duties.
Rest of at least 11 hours after on night duty Minimum requirements for a 10 beds unit :
3 physicians for morning 2 physicians for afternoon 1 physician for night
This requires 6.5 FTE per unit

Conclusion : unresolved issues
Impact of restructuration of the units Impact of creation of intermediate care units New organisation and management of the ICU Increase the attractiveness of this specialty Ethical issue – admission policy The expected shortage of ICU physicians will
increase the risk of lower quality of care No team building Lack of coherency in the clinical management of patients No involvement outside the unit No research and teaching

Recommendation for RN?
Stratification in three levels of care Level 1 : 1 RN for 1 patient Level 2 : 1 RN for 2 patients Level 3 : 1 RN for 4 patients
In France and at the bed side 1 RN for 2.5 patients 1 Helper for 4 patients

What happen if these recommendations are not fulfilled?
Reduction of the number of beds Impact for the non admitted patients? Regional regulation Number of ICU beds/100,000 inhabitants
Increase of work load for each individual RN Impact on quality of care Nosocomial infection Burn out and turn over Weaning procedures

MODELS FOR FORECASTING THE NUMBER OF EMERGENCY DEPARTMENT VISITS Wargon M, …. Guidet B. Emergency Med J (in press).
We reviewed articles retrieved by a Medline search for studies of models designed to predict patient attendance in EDs or walk-in clinics.
Only 9 studies were identified. Most of the models used to predict patient volume
were either linear regression models including calendar variables or time series models. These models explained 31% to 75% of patient-volume variability.
Although day of the week had the strongest effect on patient volume, this variable explained only part of the variability, whose causes remained largely unidentified. Adding meteorological data failed to improve model performance.
