Grant et al reported the PROACCT score (Prediction of Acute Care Use During Cancer Treatment) for patients receiving systemic cancer therapy. The authors are from Princess Margaret Cancer Centre, University Health Network (Toronto), University of Toronto and ICES Toronto.
Patient selection: adult >= 18 years of age receiving systemic cancer therapy
Outcome: requiring acute care within 30 days of starting therapy
Parameters:
(1) age in years
(2) history of emergency room visit in the past 12 months
(3) treatment and tumor combination risk

where:
• The presence of a very low risk combination is inferred from Table 4.
total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 13
• The higher the score the greater the risk of requiring acute carte.
