Table 3. Comparison of the total tests performed in matched cohorts tested using Fisher’s exact test.
ASA - American Society of Anesthesiologists, NICE - National Institute for Health and Clinical Excellence, N - Total number, LFT - liver function tests, RFT - renal function tests, PT - prothrombin time, INR - international normalized ratio, APTT - activated partial thromboplastin time, HbA1c - glycosylated hemoglobin, TFT - thyroid function test, CXR - chest x-ray, ECG - electrocardiogram). Group A represents routine investigation, and group B represents surgery and patient specific investigation.
