Risk Factors of McLaughlin et al for 30-Day Morbidity After Urological Surgery from the National Surgical Quality Improvement Program

 

Adverse outcomes constituting morbidity: 46+ complications listed in the appendix (a slightly shorter list is given in Table 1)

 

Major risk factors for morbidity (odds ratio 12-14):

(1) diabetes with end-organ damage

(2) congestive heart failure

 

Additional risk factors (odds ratios 2-4):

(1) blood transfusion during surgery

(2) prolonged operative time

(3) low serum albumin (<= 3.5 g/dL)

(4) quadriplegia or quadriparesis

(5) history of angioplasty

(6) hydronephrosis

 

where:

• The impact of diabetes without end-organ damage is less.

• Some risk factors are known before surgery and some after surgery. A preoperative assessment can identify most patients at risk for morbidity.
