Statistical analysis of monitoring examinations in chronic peritoneal dialysis program.

In dialysis centres the major part of laboratory tests is indicated by the routine monitoring strategy of the centre and not by the evidence of a new complication to be diagnosed. The aim of our study was to define an improved strategy, minimizing financial costs without loss of information. Findings of routine laboratory check-up of eleven patients undergoing chronic intermittent peritoneal dialysis were analysed. Using univariate and multivariate functions a considerable part of the laboratory test results can be estimated or predicted. From pre-dialysis measurements on serum the post-dialysis serum creatinine urea and uric acid levels can be predicted. The serum level of protein and hemoglobin can be estimated using the results of previous tests (performed maximum 7 weeks earlier) and current measurements on dialysate.
