    Hospitalization in the first year of renal replacement therapy for end-stage renal disease

    Background: The requirement for hospitalization of patients on dialysis is likely to be a surrogate marker of age and comorbid diseases. It may also reflect the level of care delivered, and substantially increases the cost of this expensive therapy.Aim: To identify the factors most strongly associated with hospitalization.Design: Prospective population study.Methods: Data were recorded for all patients starting RRT in Scotland over one year, including the reasons for and duration of, each hospital admission during the first year of RRT. Factors most strongly associated with hospitalization were determined by Poisson regression analysis.Results: Overall, 526 patients were admitted to hospital on 1668 occasions (median 3, IQR 1-4) for 13 384 days (median 13, IQR 4-35). Formation of vascular access for haemodialysis (HD) was the most frequent reason for admission, followed by infections. Age, comorbidity, mode of presentation for RRT and primary renal diagnosis were all significantly associated with prolonged hospitalization. Attainment of UK Renal Association standards for urea reduction ratio and serum albumin concentration, and vascular access in the form of arteriovenous fistulae were associated with less hospitalization in patients treated with HD by 90 days.Discussion: Patients in their first year of RRT have a high requirement for in-patient care, 8.6% of patient treatment days being spent in hospital. Vascular access formation, failure and complications account for a large proportion of this. Age and comorbidity prolong the time spent in hospital. As the RRT population continues to increase, with older patients and those with greater comorbidity, in-patient facilities must also expand.Background: The requirement for hospitalization of patients on dialysis is likely to be a surrogate marker of age and comorbid diseases.

    Acute renal failure requiring renal replacement therapy: incidence and outcome

    Background: Renal replacement therapy (RRT) for acute renal failure (ARF) may be provided in many settings within the hospital. Such patients require a high level of care and often have a poor prognosis. No prospective studies have accurately defined this population, making the prediction of necessary resources and the planning of services difficult. Aim: To ascertain the incidence, causes and outcomes of acute renal failure requiring renal replacement therapy in Scotland. Design: A prospective observational census of all clinical areas providing renal replacement therapy in three Scottish health boards (Grampian, Highland, Tayside). Methods: Patients were identified by liaison with each unit providing RRT. Factors precipitating renal failure and reasons for RRT were recorded at the time of initiation. Comorbid disease burden was scored using the Charlson index. Patient status at 90 days was assessed from case‐notes, contacting general practitioners where necessary. Results: 375 patients per million population per year received RRT; 203 per million per year for either ARF or acute‐on‐chronic renal failure. 73.5% of patients receiving RRT for ARF died within 90 days, 23.5% became independent of RRT. The median duration of hospital admission was 19 days. Discussion: The annual incidence of ARF requiring RRT is just over 200 per million population, almost twice that of end‐stage renal disease requiring RRT. Such treatment places high demands upon health care resources

    Comparison of patient survival in non-diabetic transplant-listed patients initially treated with haemodialysis or peritoneal dialysis

    Background. It is still not known whether patients survive longer on one modality of dialysis compared to the other. We have tried to answer this question using data from the Scottish Renal Registry. Methods. To avoid the confounding effects of co-morbidity, we limited our survival analysis to those patients listed for a renal transplant and excluded patients with a primary renal diagnosis (PRD) of diabetic nephropathy. We studied patients starting dialysis between 01 January 1982 and 31 December 2006. Results. Three thousand one hundred and ninety-seven patients fulfilled our criteria. A Kaplan-Meier plot showed no difference in survival between initial dialysis modality (log-rank P = 0.996). In the Cox regression model, initial dialysis modality was not a significant predictor of survival; hazard ratio = 0.97 (95% CI 0.80 to 1.18) after adjusting for age, sex and PRD. Age at the start of dialysis, hazard ratio = 1.05 (95% CI 1.04 to 1.06) and a PRD group of ‘multi-system disease’ or ‘unknown’ were found to significantly influence survival. When survival was also censored for change in modality, there was no difference in survival over the whole study period with the hazard of death for patients on haemodialysis compared to those on peritoneal dialysis being 1.04 (95% CI 0.78 to 1.38; P = 0.803). Age at the start of dialysis remained a significant predictor of death. Conclusions. This study shows that there was no survival advantage between initial dialysis modalities in non-diabetic patients who are deemed healthy enough for listing for a renal transplant
