[Assessment of activity of care of a nutritional support multidisciplinary team in the follow-up of total parenteral nutrition].

INTRODUCTION: In total parenteral nutrition (TPN) nutritional support multidisciplinary teams (NSMT) must provide a high quality nutritional assistance based on evidence and daily follow-up of patients with TPN.

OBJECTIVES: To assess the degree of adherence to quality standards of care provided to patients on TPN by the NSMT in two consecutive annual periods, according to structure, procedure, and outcomes indicators, previously defined in the team working protocol.

PATIENTS AND METHODS: Prospective study of all patients that received TPN at our Center (421-bed general teaching hospital) during the years 2002 and 2003, using the data introduced in NUTRIDATA by daily follow-up of clinical and analytical conditions, and nutritional and non-nutritional complications, comparing both periods and considering an statistical significance level of p < 0.05.

RESULTS: One hundred and sixty-three patients and 145 patients received TPN during 2002 and 2003(65.9% male), respectively, with similar parameters of gender, age, indications for TPN, baseline nutritional status, mean nutritional supply, and non-nutritional complications. As to the different quality indicators established in the comparative study, we found a significant improvement in 2003 vs. 2002 in relation to initial anthropometrical assessment (71.03% vs 51.53%; p < 0.001), initial biochemical assessment (97.93% vs. 92.63%; p < 0.04), performance of systematic monitoring analysis (84.83% vs. 71.78%; p < 0.01), hypernatremia incidence (8.27% vs. 15.34%; p = 0.05) and moderate hyperphosphatemia (26.89% vs. 40.49%; p < 0.02), TPN ending for clinical improve- ment (76.60% vs. 64.40%; p = 0.04), and reduction of days on TPN (15.74 +/- 20.43 vs. 11.88 +/- 8.34; p < 0.02), the impaired electrolyte levels significantly improving as a whole. We also observed a non-significant trend towards an improvement of adequacy of TPN indications, hyperphosphatemia, severe hypophosphatemia, total stay, and post-surgical stay, in 2003 vs. 2002.

CONCLUSIONS: The NSMT experience shows that analysis of indicators based on quality standards, in two successive annual periods allows assessing the improvement of efficiency of nutritional intervention in hospital-admitted patients with TPN with regards to indication, assessment, follow-up, and course.
