1. Can We Justify ICU Refusal for Cancer Patients ? Elie AZOULAY, MD Medical ICU, Saint Louis Teaching Hospital Paris, France 14th ESICM Annual Congress Geneva, Switzerland 30 Sept-3 Oct 2001

2. Triage decisions to ICU When evaluating a patient with a severe acute illness, the ICU physician must determine: (i) the diagnosis, prognosis, and treatment (ii) whether or not ICU admission is warranted (iii) and if it is, whether the patient, if competent, consents to ICU admission.

3. Triage decisions to ICU The answer to the second question is a daily dilemma for ICU physicians. Its determinants have been reported as related to: (i) the number of beds available in the ICU (ii) patient characteristics and comorbidities (iii) and the characteristics of the acute illness (severity, reversibility, and predicted residuals and quality of life after ICU discharge)

7. Cancer patients u ICU physicians are often reluctant to admit cancer patients because they require: –a large amount of work –costly resources –in-depth knowledge of hematology by the ICU staff for little gain, since their outcome is frequently unfavorable. for little gain, since their outcome is frequently unfavorable. u “Only cancer patients with a chance of being cured, who agree to undergo supportive therapy, and those with best chances of benefiting from intensive care should be admitted by priority”. Sculier Curr Opin Oncol 1991;3:656-662

29. Can We Justify ICU Refusal for Cancer Patients ? Yes … But,

30. Conclusion : Patient selection, not routine denial u Cancer patients are a heterogeneous group. u Improvements in both intensive care and oncohematological management have stripped classic predictors of ICU mortality of much of their value. u Allo-BMT patients remain poor candidates for ICU admission, above all when they need intensive management

31. The doctrine of ‘double effect’ in triage ? –Opening widely the filter for ICU admission may avoid depriving patients from a chance to recover, but may allow physicians to perform more end-of-life decisions Cuttini M, Lancet. 2000;355:2112-8 –Do we have (need) more beds to admit everyone for a selected period to better estimate the reversibility of the disease, or should we only take into account malignancy and comorbidities? We above all need to clear a double talk Sulmasy DP, Arch Intern Med 1999;159:545-50

32. Everything that should be done... u When patients, oncohematologists and ICU physicians feel that ICU admission is reasonable, all potentially effective treatment methods should be used in the ICU. u Triage to the ICU using a multiplidiscinary method should place CICPs on the same level of priority as any other patient with other comorbidities

33. Is ICU selection by intensivists still a dilemma for cancer patients ? Patients and family members Hematologists and oncologists ICUphysicians ICU ADMISSION? Multiple step selection … Are guidelines necessary? For whom? Studies are ongoing... Social context Social context

34. Need for Guidelines? u Guidelines are important because they offer a basis for discussion. u However, doctors need to know when they should transgress guidelines.
