A Simple Clinical Tool for Increasing Enrollment on a Kidney Transplant Waiting List for Patients Aged Over 70 and Initiating Dialysis

Study Overview
=================
Brief Summary
-----------------
The main objective of this study is to show that the systematic use of a prognostic score as early as possible after the initiation of dialysis in patients over 70 years of age and with a good prognosis at 3 years of dialysis results in an increase in the number of entries on a kidney transplant waiting list at 12 months after the initiation of dialysis. This prospective assessment is carried out as part of a historico-prospective before-after study in parallel with a survey of changes in national practices over the same time period via a here-elsewhere type study. Historical data (i.e the. before period) will include incident dialysis cases during the calendar years 2013, 2014 and 2015 before the start of the prospective phase (i.e. after period, which is represented by the current declaration); since a preliminary study demonstrated that the data are comparable from 2011 to 2013, we will use the average of data thus obtained. Historical data will be retrieved from the REIN (The French Renal Epidemiology and Information Network) registry data and will be validated by investigators at each center.

Detailed Description
-----------------
The secondary objectives are: A. To show that the systematic use of the score at the initiation of dialysis can shorten the registration delay on a kidney transplant waiting list; to evaluate the time between initiation of dialysis and registration on a national waiting list for kidney transplants, while assessing the duration of the pre-transplant assessment. B. To identify barriers to registration on the kidney transplant waiting list as well as the related time delay in this population (medical and non-medical factors), the rates and causes of patient refusal for registration and the possible evolution this refusal over time. C. To evaluate the economic impact of the introduction of the renal transplant clinical prognostic score.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Chronic dialysis patients<br>The study population consists of patients over 70 (≥) and under 85 years (<) of age with stage 5 chronic renal disease and initiating a first session of chronic dialysis in the Languedoc-Roussillon and Midi-Pyrénées regions. Eligible patients must have a 3 year prognostic mortality score less than (<) 7 points (Dusseux et al. 2015). Intervention: Systematic use of a prognostic score | Other: Systematic use of a prognostic score<br>* The prognostic score is given in Dusseux et al 2015. It will be used as soon as possible after the initiation of dialysis.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The % number of registrants on the kidney transplant waiting list |  | 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Delay between the initiation of dialysis and inclusion on the kidney transplant waiting list | This outcome integrates the the duration of initial assessment and is measured by the difference between the start and end dates of the pre-transplant assessment. | 12 months | 
| The number of refusals by patients for registration on the kidney transplant waiting list |  | 12 months | 
| In case of patient refusal for registration, the reasons why (qualitative approach) |  | 12 months | 
| The number of cases where there is a medical contra-indication for registration on the kidney transplant waiting list |  | 12 months | 
| In case of a medical contra-indication for registration on the kidney transplant waiting list, the cause (qualitative approach) |  | 12 months | 
| The cost of care associated with dialysis patients and dialysed-and-then-transplanted patients will be estimated from the point of view of the French health insurance system |  | 12 months |
