Abstract Details

Purpose:

To study the relationship of the American Society of Anesthesiologists (ASA) Classification with Outcomes of Cataract Surgery

Setting:

Veterans Affairs Healthcare System, United States of America

Methods:

Our study analyzed the outcomes of cataract surgery. Corrected distance visual acuity (CDVA), unanticipated events, and vision-related quality of life (VROL) were assessed using the National Eye Institute Visual Function Questionaire (NEI-VFQ), comparing ASA classes I through IV. For some analyses, ASA classes I and II were assigned as Group A and ASA classes III and IV were assigned as Group B.

Results:

Of 4923 cases, 875 (17.8%) were Group A, 4032 (81.9%) Group B, 16 (0.3%) missing data. Mean CDVA and composite NEI-VFQ score improved after cataract surgery in both (P<.0001); Group A had better mean postoperative CDVA and postoperative VFQ scores than Group B (P<.0001). Higher ASA class was associated with increased risk for 2 unanticipated events: clinically significant macular edema (CSME) (Group A: 4 [0.47%] versus Group B: 50 [1.28%]; adjusted odds ratio [OR], 3.02; 95% confidence interval [CI], 1.02-13.05; P=0.04) and readmission within 30 days (2 [0.23%] versus 56 [1.41%]; OR, 8.26; 95% CI, 1.71-148.62; P = 0.004)

Conclusions:

Among Veterans of the United States of America, the ASA classification could be an important predictor of VRQL and visual outcomes. In this cohort, it was associated with an increased risk for 2 serious unanticipated events: CSME and readmission to the hospital, both costly and undesired outcomes.
