Study Details

Study Description

Brief Summary

The smartNTx trial: Prospective, randomized controlled trial (RCT) to investigate additional interventional telemedical management versus standard aftercare in kidney transplant recipients (KTR).

STUDY PURPOSE: To demonstrate that additional interventional telemedical management will lead to a higher chance for long-term graft survival, increase adherence, quality of life (QoL), and reduce complications and healthcare costs after kidney transplantation.

Condition or Disease Intervention/Treatment Phase
  • Combination Product: Additional interventional telemedical management
N/A

Detailed Description

This is a 1-year, prospective, randomized, 2-armed, parallel group multicenter trial in 3 German Kidney Transplant Centers (KTCs) to demonstrate that additional and continuous interventional telemedical management will lead to a better composite endpoint of 7 key outcome variables (hospitalizations, length of hospitalization, development of a de-novo donor specific antibody (DSA), medication adherence, tacrolimus intra-patient variability, blood pressure control and renal function after kidney transplantation). All patients will receive the same routine posttransplant aftercare. Patients in the interventional arm will receive a predefined additional telemedical management including regular telemedicine visits and automatic data transfer (e.g. vital signs, well-being, medication plan laboratory data and chat) between the patient at home and KTC through a certified smartphone application (comjoo business solutions GmbH, Berlin, Germany). Furthermore, home nephrologists of patients in the interventional arm are invited to participate in automatic data transfer of key variables (such as vital signs, laboratory data) with KTC. A separate telemedicine team will constantly review the incoming data according to a predefined protocol and eventually contact the patient and/or the home nephrologist in order to start appropriate interventions.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Intervention group "Additional telemedical management"

Patients in the interventional arm will receive a predefined additional telemedical management including regular telemedicine visits and automatic data transfer (e.g. vital signs, well-being, medication plan laboratory data and chat) between the patient at home and KTC through a certified smartphone application.

Combination Product: Additional interventional telemedical management
Predefined additional telemedical management including regular telemedicine visits and automatic data transfer (e.g. vital signs, well-being, medication plan laboratory data and chat) between the patient at home and KTC through a certified smartphone application.

No Intervention: Control group "Routine posttransplant aftercare"

Patients in the control group will receive routine posttransplant aftercare.
