Enhancing the Cardiovascular Safety of Hemodialysis Care (Dialysafe)

Overview

The purpose of this study is reduce episodes of intradialytic hypotension, low blood pressure during a hemodialysis session, in patients with End Stage Renal Disease (ESRD). Recruitment will take place on the clinic level rather than the patient level.

Detailed Description

When a person's kidneys stop working, he or she has end-stage renal disease (ESRD). Individuals with ESRD cannot live without either dialysis therapy-in which a machine performs the functions of the kidneys-or a kidney transplant. Dialysis must remove fluid as well as toxins in the blood. People with ESRD have a high risk for death, and the usual cause is cardiovascular disease. Most people in the United States who have ESRD get hemodialysis therapy in a clinic for four hours at a time, three times a week. The stability of hemodialysis sessions varies, and many sessions become unstable from low blood pressure and other complications. Unstable dialysis sessions can result in negative symptoms, like fatigue. Dialysis instability is an important problem. Session instability is linked to injury to the heart and other organs. Patients who have unstable dialysis sessions are more likely to end up in the hospital or die than are those who have stable sessions. Session instability is preventable. The main causes of instability are removal of fluid from a patient too fast or removal of too much fluid. Session instability results from many factors: decisions made by patients, and decisions by healthcare providers. Presently, the way to best improve the stability of dialysis is not clear. Dialysis clinics approach this problem differently, and there is variation among clinics in how often hemodialysis sessions become unstable. In partnership with the National Kidney Foundation and Fresenius Medical Care North America, the investigators will test two interventions designed to increase the stability of patient dialysis. One intervention, multimodal provider education, focuses on dialysis facility care teams. It includes team training, online education, and a checklist. Another intervention, patient activation, focuses on patients. It includes peer mentoring by trained ESRD patients. Mentors will hold with other patients multimedia-aided meetings that include skills instruction and role modeling. These interventions have been successful in hospital care and in chronic disease care, and the investigators will adapt them to dialysis safety. The investigators will then conduct a study in 20 dialysis facilities in different parts of the United States. Five facilities will get the provider education only; five will get the patient activation intervention only; five will get both interventions; and five will get no interventions. The investigators will test whether session stability improves in the facilities that get either intervention over the 48-week study period. This study is expected to clarify whether these interventions can make dialysis safer for ESRD patients. This will inform hemodialysis care providers on whether to pursue provider-focused or patient-focused safety interventions, or both. People on hemodialysis will also have information to help them decide whether to become engaged in their session stability, and the intervention will help them learn how to do so.

  • Experimental: Provider Education
    • This arm focuses on dialysis facility care teams. It includes team training, online education, and checklists.
  • No Intervention: No Intervention
    • Patients in clinic receive usual care.
  • Experimental: Patient and Provider
    • This arm includes both Patient Activation and Provider Education interventions

Clinical Trial Outcome Measures

Primary Measures

  • Dialysis Session Stability
    • Time Frame: 48 weeks
    • Binary variable whereby session is labeled unstable (=1) or stable (=0). Sessions will be labeled unstable (=1) if: (1) intradialytic hypotension occurs, which is defined as systolic blood pressure falling below 100.

Secondary Measures

  • Fluid Adherence
    • Time Frame: 48 weeks
    • Measured by interdialytic weight gain (in Kilograms), which is the weight gained between dialysis sessions.
  • Dialysis adherence – minutes missed
    • Time Frame: 48 weeks
    • Measured as the number of minutes of prescribed dialysis time missed per week (number of prescribed minutes-number of actual minutes).
  • Dialysis adherence – sessions missed
    • Time Frame: 48 weeks
    • Measured as the number of missed sessions per week (number of prescribed sessions-number of actual sessions).
  • Patient symptoms – post-dialysis recovery time
    • Time Frame: 48 weeks
    • Measured at each session as patient recovery time after dialysis, reported on a survey item on an ordinal scale from “within minutes” to “did not recover before the next scheduled dialysis session.”
  • Patient symptoms – symptom burden
    • Time Frame: 48 weeks
    • Measured as the total number symptoms reported by the patient at each session (each symptom treated as one, then added to create total symptoms).
  • Quality of Life-KDQOL
    • Time Frame: 52 weeks
    • Total score measured by adding responses on the Kidney Disease Quality of Life survey (KDQOLTM-36 Version 1).
  • Hospitalization
    • Time Frame: 48 weeks
    • Binary variable, measured as whether or not a patient was hospitalized for any reason, where hospitalization=1 and no hospitalization=0 (“all-cause hospitalizations”).
  • Mortality
    • Time Frame: 48 weeks
    • Binary variable, measured as whether or not a patient died of any cause, where mortality=1 and no mortality=0 (“all-cause mortality”).
