Background And Purpose:
The level of patient satisfaction is a result of a complex set of interactions between the patient and the health care provider. It is important to quantify satisfaction with care because it involves the patient in the care experience and decreases the potential gap between expected and actual care delivered.
Methods:
We tested a preliminary 23-item instrument to measure patient satisfaction with general anesthesia care. The rating scale Rasch model was chosen as the framework.
Results:
There were 10 items found to have sufficient evidence of stable fit statistics. Items included 2 questions related to information provided, 2 questions related to concern and kindness of the provider, and 1 question each for interpersonal skills of the provider, attention by the provider, feeling safe, well-being, privacy, and overall anesthesia satisfaction.
Conclusion:
Such actions as providing enough time to understand the anesthesia plan, answering questions related to the anesthetic, showing kindness and concern for the patient, displaying good interpersonal skills, providing adequate attention to the patient, providing a safe environment that maintains privacy and provides a sense of well-being are important actions that are well within the control of individual anesthesia providers and may lead to improved care from the perception of the patient.
