Patient satisfaction for carotid endarterectomy performed under local anaesthesia

To develop, validate and use a procedure specific questionnaire to evaluate patient experience and satisfaction following carotid endarterectomy (CEA) under either general (GA) or local anaesthesia (LA).

Twenty post-CEA patients were interviewed. Data were content analysed and recurrent themes used to generate the specific carotid endarterectomy experience questionnaire (CEA-EQ). The CEA-EQ consists of 15 pre-op and 13 postoperative questions. Validity was established by correlation with the FRS Patient Satisfaction with Surgical Services (SSSQ) and State form of the State Trait Anxiety Inventory (STAI-S) in 69 patients (35 LA, 34 GA). Subsequently 88 patients randomised to GA CEA and 88 to LA CEA received the CEA-EQ. A local anaesthetic intraoperative experience questionnaire (LA-EQ) was also developed and given to LA patients only.

Validity was confirmed through significant correlations with the STAI-S (r=0.67, p<0.001) and the SSSQ (r=0.44, p<0.001). In the randomised prospective study response rates were greater than 90%. Overall experience and satisfaction with CEA was high. There was no statistically significant difference in anxiety, satisfaction or overall experience between anaesthetic techniques. LA CEA was associated with a significantly better perception of recovery. The majority of LA patients found the procedure acceptable.

The CEA-EQ is a valid tool to assess qualitative aspects of CEA patient care. Overall satisfaction and experience with CEA is good and not related to anaesthetic technique. LA CEA is not associated with any increased anxiety, is tolerated by the majority of patients and is associated with a better perception of recovery.
