Objective
To evaluate the relationship between the preoperative assessment guide of the Catalan Society of Anesthesiology and Geriatrics (SCARTD and SCGiG) in the elderly patient with morbidity and mortality after surgery of moderate to high risk.

Methods and material
Prospective observational study in patients aged > 70 years or > 60 years with associated co-morbidity scheduled for elective surgery of moderate to high aggressiveness. Data were collected from 60 patients in the preoperative visit to whom the Katz questionnaires, Pfeiffer Test or Short Portable Mental Status Questionnaire (SPMSQ) and Mini-Nutritional Assessment Short Form (MNA-SF) were administered in order to assess respectively their functional, cognitive and nutrition status; with a follow-up 30 days after the intervention. 
The variables were: demographic data, post-operative cognitive dysfunction (POCD), respiratory complications, cardiovascular, local and systemic infection, renal failure, endocrine-metabolic complications, hospital stay, mortality and readmission at 30 days. 

Results 
The average age of the sample was 82 ± 8 years and 60% were women. Statistically a significant association between the MNA-SF and 30-day mortality was found, as well as a relationship between the Pfeiffer Test, Katz and POCD and between the Pfeiffer Test, the ASA grade, the MNA-SF and the rate of readmission at 30 days (p <0.05). 

Conclusion 
The scores included in the preoperative assessment guide in patients of advanced age of SCARTD and SCGiG seem to be related to the rate of postoperative complications, mortality and readmission rate within 30 days.
