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.

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.

Inclusion Criteria:

• Informed consent signed and dated by study patient and investigator/authorized physician
• Age of 18 -80 years
• Ability to understand the nature and requirements of the study
• Literacy in Turkish including the ability to read with regards to visual acuity and the ability to understand what is read
• General ability to use a tablet (the study nurse will instruct the patient how to use the study-tablet during the conduct of the study)
• To be on stable maintenance hemodialysis (HD) for over 3 months (prevalent patients)

Exclusion Criteria:

• Any conditions which could interfere with the patient's ability to comply with the study
• Previous participation in the same study
• Participation in an interventional clinical study during the preceding 30 days
• Serious life-limiting co-morbid situations, namely active malignancy, active infection, end-stage cardiac, pulmonary, or hepatic disease, which causes life-expectancy less than a year,
• Acute cardiovascular events including myocardial infarction, stroke and unstable angina pectoris requiring hospitalization within the last 6 months,
• To have cognitive or mental co-morbidities which prevent reliable answering of questions
