Description of intervention(s) / exposure
We sought to learn prospectively the likely survival of patients not planned for dialysis and whether or not they could be provided with reasonable quality of life and control of their symptoms.
This prospective observational study was over 4 years.
Intervention code [1] 288650 0
Not applicable
Comparator / control treatment
The comparator being studied are the outcomes of patients attending the Renal Supportive Care (RSC) clinic.
These outcomes will be compared to the patients attending standard renal clinics (Pre-Dialysis clinic).
Control group
Active

Outcomes
Primary outcome [1] 291325 0
Survival - time to death, or renal replacement therapy
Timepoint [1] 291325 0
Monitored over the 4 year study period
Primary outcome [2] 291326 0
Maintenance or improvement of symptoms. Symptoms were assessed using the Memorial Symptom Assessment Scale (MSAS-SF), a validated tool for assessing patients’ symptoms, as well as by using the POS-S (renal) survey for those patient in the Renal Supportive Care non-dialysis group. Symptoms were assessed as both the number of symptoms and the total symptom score.
Estimated glomerular filtration rate (eGFR) was repeated each 6 months along with repeat assessment of symptom burden by the MSAS-SF survey tool.
Timepoint [2] 291326 0
Monitored over the 4 year study period and recorded at 6 monthly intervals for each patient.
Primary outcome [3] 291327 0
Maintenance or improvement of quality of life.
Quality of life was assessed using the Short Form-36 (SF-36). Estimated glomerular filtration rate (eGFR) was repeated each 6 months along with repeat assessment of quality of life by the SF-36 survey tool.
Timepoint [3] 291327 0
Monitored over the 4 year study period and recorded at 6 monthly intervals for each patient.
Secondary outcome [1] 306531 0
Secondary outcomes included hospitalisations. This involves data linkage to patient medical records.
Timepoint [1] 306531 0
Monitored over the 4 year study period for each patient

Statistical methods / analysis
The number of participants needed to achieve the study objectives was based on patients attending the clinics within the 4 year study period. All patients, who consented, were included if they satisfied the inclusion criteria during this period.
Comparison of continuous variables between groups was done using Student's t-tests or Mann-Whitney tests as appropriate. Comparison of categorical variables between groups was done using Chi-square testing. Survival was estimated by the Kaplan-Meier technique from the initial visit to the relevant clinic and from the time eGFR fell below 15ml/min. Factors influencing survival were determined by multivariable logistic regression analysis. Factors tested in the univariable analysis included age, weight, eGFR at initial visit, BMI, Haemoglobin, serum albumin, Calcium, Phosphate, PTH, gender, diabetes, dementia, co-morbidities, smoking and nutritional status. All factors significant on univariable analysis were tested by step-wise multivariable analysis. Change in symptoms or QOL over time were categorized into "stable", "improved" or "worse". Chi-square testing was used to compare the change in symptoms and QOL between groups. Analysis was by intention to treat and level of significance was 0.05. Analyses were undertaken using SAS statistical software version 9.2.
