Chronic peritoneal dialysis in octogenarians
Bibliographic record
Abstract
BACKGROUND: During the past few decades the pattern of end-stage renal failure disease has changed with increasing number of elderly patients admitted for dialysis. In spite of their increasing number, little is known about the optimal mode of therapy of the 'old old' (those >or=80 years) patients. METHODS: In this retrospective study, we analysed the results of treatment of 31 non-institutionalized 'old old' patients at Toronto Western Hospital (17) and Scarborough General Hospital (14) and seven institutionalized patients in chronic care, Riverdale Hospital. The patients were on CAPD with Twin-bag Baxter (28) or Home Choice, Baxter or Fresenius CCPD system (10). Patients were screened at the CAPD clinic when routine blood investigations were done. Patient and technique survival, initial and final laboratory data (last visit or before death) and complications related/unrelated to dialysis method are presented. RESULTS: Multiple comorbid conditions were present at the start of the treatment and new added during treatment; very few were dialysis-related. The majority of non-institutionalized patients required assistance of home-care nurse to perform dialysis. Peritonitis (1/28.6 patient months) and exit-site infection rate (1/75.1 patient months) were low and responded to treatment. Incidence of peritonitis was higher among institutionalized debilitated patients (1/5.3 patient months). Incidence of hospitalization was 1/14.7 patient months and patients spent in hospital 7.5 days/patient year. Forty-seven per cent of patients survived 24 months; 39% survived 30 months. Technique survival was 91.5% at 12 months and 81.4% at 30 months. Poor appetite and malnutrition were frequent among very old patients. Patients and their families were motivated for treatment and discontinuation of dialysis was not higher than described elsewhere in literature. CONCLUSIONS: This study has demonstrated that chronic peritoneal dialysis could be recommended as a safe and suitable modality of treatment of end-stage renal failure in old old patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
