ABSTRACT
BACKGROUND/AIMS: Radiocontrast nephropathy (RCN) is a common and costly form of acute renal failure. Current preventative strategies include the use of intravenous (IV) fluids and the discontinuation of nephrotoxic medications at the time of radiocontrast administration. We sought to determine whether providers employ these strategies in high-risk patients to limit the development of RCN. METHODS: High-risk patients undergoing procedures using radiocontrast media over a 12-month period were identified. Medical records were reviewed for all subjects who developed RCN and a randomly selected 25% of patients without RCN. Patients with a contraindication to IV volume expansion were excluded. Medical records of the remaining patients were reviewed to determine whether IV fluids were administered and whether NSAIDs or COX-2 inhibitors were prescribed at the time of contrast administration. RESULTS: RCN developed in 8% of patients overall. Of 144 patients eligible for IV volume expansion, 16% failed to receive any IV fluids. When IV fluids were employed, their dose and timing of administration varied significantly by treating specialty and procedure. NSAIDs and COX-2 inhibitors were prescribed to 8% of patients. CONCLUSIONS: Commonly accepted strategies for the prevention of RCN are underutilized. Quality improvement efforts are needed to increase the use of these two simple prophylactic measures.

BACKGROUND: There has been little research on the potential value of palliative care for dialysis patients. In this pilot study, we sought (i) to identify symptom burden, health-related quality of life (HRQoL) and advance directives in extremely ill haemodialysis patients to determine their suitability for palliative care and (ii) to determine the acceptability of palliative care to patients and nephrologists. METHODS: Nineteen haemodialysis patients with modified Charlson co-morbidity scores of > or =8 were recruited. Each completed surveys to assess symptom burden, HRQoL and prior advance care planning. Palliative care specialists then visited patients twice and generated recommendations. Patients again completed the surveys, and dialysis charts were reviewed to assess nephrologists' (i) compliance with recommendations and (ii) documentation of symptoms reported by patients on the symptom assessment survey. Patients and nephrologists then completed surveys assessing their satisfaction with palliative care. RESULTS: Patients reported 10.5 symptoms, 40% of which were noted by nephrologists in patients' charts. HRQoL was significantly impaired. Thirty-two percent of patients had living wills. No differences were observed in symptoms, HRQoL or number of patients establishing advance directives as a result of the intervention. Sixty-eight percent of patients and 76% of nephrologists rated the intervention worthwhile. CONCLUSIONS: Extremely ill dialysis patients have marked symptom burden, considerably impaired HRQoL and frequently lack advance directives, making them appropriate candidates for palliative care. Patients and nephrologists perceive palliative care favourably despite its lack of effect in this study. A more sustained palliative care intervention with a larger sample size should be attempted to determine its effect on the care of this population.

PURPOSE: Dialysis patients frequently have comorbid conditions. We examined the effects of age and comorbid conditions on technique failure (i.e., transfer to hemodialysis), death, hospital costs, and kidney transplantation in patients treated with peritoneal dialysis. METHODS: We studied 97 patients who began peritoneal dialysis from January 1, 1993, to December 31, 1998, at the University of Pittsburgh outpatient dialysis unit. Demographic characteristics, comorbid conditions, and outcomes were determined by reviewing the Medical Archival Retrieval System database and outpatient records. Because the comorbidity (Charlson) score was colinear with age, we used a modified version of the score without an age component. Low, moderate, and high comorbidity groups were defined based on the 33rd and 66th percentiles of the comorbidity score. RESULTS: In multivariate-adjusted models, each decade increase in age was associated with an increased risk of death (hazard ratio [HR] = 1.7; 95% confidence interval [CI]: 1.1 to 2.5) and technique failure (HR = 1.5; 95% CI: 1.0 to 2.3). High (versus low) comorbidity was associated with an increased risk of death or technique failure (HR = 3.5; 95% CI: 1.0 to 12) and significantly higher average inpatient costs. There were no differences in age or comorbidity score between patients who transferred to hemodialysis and those who died. CONCLUSION: Patients who are older and more ill have a greater risk of death and of transfer to hemodialysis from peritoneal dialysis.
