Study summary

Development, feasibility testing and validation of a Survey Set to Measure Patient-Reported Outcomes among Hemodialysis Patients in Turkey: Creating and testing an electronic patient questionnaire that is suitable to measure health-related quality of life in Turkish dialysis patients in clinical as well as in home care settings.

Read the detailed description

Individuals with chronic kidney disease represent a growing population in adult and pediatric practices. This has resulted in a drive to optimize patient care and outcomes. Historically, healthcare outcomes focused on morbidity, mortality or complication rates, but failed to provide meaningful data on the value of medicine to patients and the quality of life gained or lost. Several studies have revealed that treatments aimed at minimizing morbidity and mortality in end-stage renal disease (ESRD) have very often been ineffective. Therefore, attention to HRQOL among ESRD patients is crucial.

The aim of this pilot study is creating and testing an electronic patient questionnaire that is suitable to measure health-related quality of life in Turkish dialysis patients. This questionnaire consists of the PROMIS Cognitive Function and Abilities Subset, the PROMIS-29, a new post-dialysis recovery time module, the MOS-Social Support Scale (MOS-SSS), Subscales of the KDQOL SF 1.3 (sexual function \& cognitive function), the General Self-Efficacy Scale and the Health Services Utilization And Productivity Loss Survey which are to be delivered together on a tablet computer.
