The absence of an accepted model for risk-adjustment of acute medical admissions leads to suboptimal clinical triage and serves as a disincentive to compare outcomes in different hospitals. The Simple Clinical Score (SCS) is a model based on 16 clinical parameters affecting hospital mortality.


We undertook a feasibility pilot in 21 hospitals in Europe and New Zealand each collecting data for 12 or more consecutive medical emergency admissions. Data from 281 patients was analysed.


Severity of illness as estimated by SCS was related to risk of admission to the Intensive Care Unit (p<0.001) but not to the Coronary Care Unit. Mortality increased from 0% in the Very Low Risk group to 22% in the Very High Risk Group (p<0.0001). Very low scores were associated with earlier discharge as opposed to very high scores (mean length of stay of 2.4 days vs 5.6 days, p<0.001). There were differences in the pattern of discharges in different hospitals with comparable SCS data. Clinicians reported no significant problems with the collection of data for the score in a number of different health care settings.


The SCS appears to be a feasible tool to assist clinical triage of medical emergency admissions. The ability to view the profile of the SCS for different clinical centres opens up the possibility of accurate comparison of outcomes across clinical centres without distortion by different regional standards of health care. This pilot study demonstrates that the adoption of the SCS is practical across an international range of hospitals.
