• Rationale and Comments

    For many, preoperative tests are not necessary and add costs because eye surgeries are not lengthy and don’t pose serious risks. An electrocardiogram should be ordered if patients have heart disease. A blood glucose test should be ordered if patients have diabetes. A potassium test should be ordered if patients are on diuretics. In general, patients scheduled for surgery do not need medical tests unless the history or physical examination indicates the need for a test (e.g., like the existence of conditions noted above, heart disease, diabetes, use of diuretics, etc.). Institutional policies should consider these issues.
