The relationship between tissue loss and function: recent developments

Nutritional risk is a clinical predictor of postoperative mortality and morbidity in surgery for colorectal cancer

BACKGROUND

This study investigated whether nutritional risk scores applied at hospital admission predict mortality and complications after colorectal cancer surgery.

METHODS

Some 186 patients were studied prospectively. Clinical details, Reilly's Nutrition Risk Score (NRS) and Nutritional Risk Screening 2002 (NRS-2002) score, tumour stage and surgical procedure were recorded.

RESULTS

The prevalence of patients at nutritional risk was 31.7 per cent according to Reilly's NRS and 39.3 per cent based on the NRS-2002. Such patients had a higher mortality rate than those not at risk according to Reilly's NRS (8 versus 1.6 per cent; P = 0.033), but not the NRS-2002 (7 versus 1.8 per cent; P = 0.085). Based on the NRS-2002, there was a significant difference in postoperative complication rate between patients at nutritional risk and those not at risk (62 versus 39.8 per cent; P = 0.004) but not if Reilly's NRS was used (58 versus 44.1 per cent; P = 0.086). Nutritional risk was identified as an independent predictor of postoperative complications (odds ratio 2.79; P = 0.002).

CONCLUSION

Nutritional risk screening may be able to predict mortality and morbidity after surgery for colorectal cancer. However, the diverse results reflect either the imprecision of the tests or the small sample size.

Clinical review: Intensive care follow-up--what has it told us?

The majority of intensive care practitioners, until comparatively recently, was content to discharge surviving patients to the care of referring primary specialty colleagues who would undertake subsequent inpatient and outpatient care. With the exception of mortality statistics from clinical studies, the practitioners were thus denied the opportunity of understanding the full impact of critical illness on a patient and their family. The concept of the intensive care follow-up clinic has developed more recently, and is run commonly on multidisciplinary lines. These clinics serve a number of purposes, but importantly have drawn attention to broader patient-centred outcomes after intensive care. Investigators are just beginning to identify, and in some cases quantify, the postdischarge burden on patient and family; additional useful data have also come from follow-up of specific disease states. The purpose of the present review is to highlight some of the important issues that impact on recovery from critical illness towards an acceptable quality of postdischarge life. We have concentrated on the adult literature, and specifically on studies that inform us about the more general effects of critical illness. Head and spinal injury are thus largely ignored, as the effects of the primary injury overwhelm the effects of 'general' critical illness.
