Abstract: The objective of this clinical trial was to determine the frequency of medical tests considered unnecessary in routine preoperative evaluation for cataract surgery. Unnecessary costs with these tests were also evaluated. For patients assigned to the selective testing group, it was requested that no preoperative testing be performed unless the patient presented a new or worsening medical problem warranting medical evaluation with testing. For patients assigned to the routine testing group, three tests were requ… Show more

“…If there was a new or changing problem identified on preoperative clinical examination that would have generated testing in the absence of the planned surgery, then specific tests were conducted in the “control” group as per the direction of the attending physician. A second study was conducted in Brazil at a single center where 1025 first-eye cataract surgeries were randomized to either routine or selective testing (Lira 2001). Finally, Cavallini et al in 2004 reported on a single center study in Italy where 1276 patients scheduled for ambulatory cataract surgery were randomly assigned to a group where results of routine preoperative tests were reviewed and a group where routine medical tests were completed but kept in a sealed envelope (Cavallini 2004).…”

“…There is evidence from at least three randomized clinical trials (Cavallini 2004; Lira 2001; Schein 2000) which suggest that preoperative medical testing for cataract surgery does not protect against medical adverse events. Further, there are substantial cost savings when redundant medical testing is avoided (Imasogie 2003).…”

“…The literature has shown that for the vast majority of elderly patients with stable diseases, routine laboratory tests are a waste of time and financial resources 1,[3][4][5]12,[14][15][16]40 . In this study, about ten tests was performed per patient, and only the determination of blood glucose can be considered important for the assessment of the patients.…”

“…Although these results have no significant impact on the perioperative period 5,14 , many are very important for the long-term overall health of the patient, often playing a role of primary care. The pre-anesthetic evaluation may provide an opportunity to trace diseases such as diabetes mellitus and thereby initiate treatment early, although there was no impact on the outcome perioperative 16 .…”
