Conditional information

How this model should be used:
The PREOP scoring system can easily be implemented into daily practice as a screening measure, to support the judgment of the clinician. The high negative predictive value indicates that the scoring system can exclude the fit elderly from further evaluation, whilst a positive score might indicate that a more comprehensive assessment by a geriatrician or by means of a multidisciplinary meeting is indicated.

Strenghts and weaknesses:
A strength of the PREOP-study is its prospective and comprehensive design. A large number of medical centers participated, which further enhances the generalisability of the results. Selection bias is a limitation of the underlying study as inclusion of a consecutive series of patients cannot be guaranteed. Furthermore, cultural differences could have influenced the reporting of results and answers to questionnaires.

Assessement of model performance:
The AUC for this individual risk score was 0.81 (95% CI: 0.75-0.86). Based on the ROC, a cut-off point was set at >8, with a sensitivity of 78.7% and a specificity of 73.4%. Positive and negatieve predictive values were 40.3% and 93.8%, respectively.
