An evaluation of anesthesia patient satisfaction instruments.

Author information

University of Tennessee, Knoxville, College of Nursing, USA.


The purpose of this study was to systematically review the instruments used to obtain anesthesia-specific patient satisfaction data and to determine the degree to which each instrument controlled for measurement error bias, such as poor survey design. By using an assessment and evaluation tool developed for the present study that held proven internal reliability and construct validity, we analyzed and scored each instrument according to the presence or absence of measurement error in survey design. We found that a paucity of anesthesia-specific patient satisfaction studies exists and that patient satisfaction studies dealing with anesthesia care were erratically defined, nonstandardized, and imprecise regarding intent and method. Moreover, the simple rating forms used in most of the reviewed studies were inadequate to achieve the goal of measuring the quality of anesthesia care. One instrument, the Iowa Satisfaction With Anesthesia Scale (ISAS), developed by Dexter et al (1997), was the first found to inculcate scientifically accepted psychometric item construction algorithms, an indicator of measurement reliability. Although the ISAS holds substantial potential for future application in this realm, we recommend that it be refined further and that the search for a superlative instrument to obtain anesthesia-specific patient satisfaction continue.
