A national survey on current practice of preanaesthetic assessment in elective surgery patients in Spain.

Objective: To analyse the preanaesthetic assessment prior to elective surgery in hospitals of the Spanish National Health Care System.

Methods: A prospective cross-sectional descriptive observational survey was performed. Primary variables were patient characteristics, type of preanaesthetic evaluation and the evaluator, as well as type of support the evaluator received during patient assessment. Secondary variables included the number of operating rooms available for elective surgery, as well as preanaesthesia clinic facilities. Data were analysed by univariate and bivariate descriptive analysis.

Results: A total of 214 hospitals of the Spanish Health Care System were invited to participate, and 203 centres responded, with all of them having a preanaesthesia assessment clinic. In 183 of them (90%), elective surgerypatients were interviewed prior to their surgical intervention, and in 202 hospitals (99.5%) a anaesthesiologist physician performed the interview. In 128 hospitals (63%), anaesthesiologists were helped during preoperative assessment by nurses alone (49%) or together with auxillary nurses (14%). In 68 of hospitals (33%) they were supported only by auxillary nurses and in 7 hospitals (3%) they obtained no help at all. In 14 centres (7%) anaesthesia nurses assessed patients directly (under supervision of an anaesthesiologist physician). Hospitals with a higher volume of patients performed more preanaesthesia interviews. Hospitals with more running operating rooms received more nurse support in the preanaesthesia assessment clinic.

Conclusions: Some kind of preanaesthesia assessment clinic exists in all Anaesthesia Departments of public Spanish hospitals, although there are differences in design and organisation.
