Data collection
HD, TG, ®
To evaluate the effects of the interventions on treatment adherence among HD patients, the mean IDWG and the laboratory parameters were measured. One week before the intervention, the mean IDWG was recorded using the Seca 676 medical scale. To evaluate the reliability of the scale before recording the patients’ weight, the weight of five people in the same gown was measured twice at one-minute intervals, whose correlation coefficient was equal to 0.9. Weight measurement was also performed before undergoing HD and in hospital gowns. To prevent bias, it was practiced and supervised by a researcher and two trained nurse assistants unaware of patient groups. In the first training session, immediately after the patients were connected to the HD machines, 5 ml blood samples were taken from an arterial catheter to measure the serum K, P, total cholesterol (TC), triglyceride (TG), AL, and ferritin (FER) levels. In order to check K, Easy Electrolyte® kit and device were used. TG, AL, FER, and P level was measured by enzymatic method and Pars Azmoon® kit, bromocresol green test and Pars Azmoon® kit, ELISA method and Pishtaz Teb® kit, and UV test and Pars Azmoon® kit respectively. All biochemistry test was done by Hitachi® model 902. All the experiments were performed with laboratory devices and kits, and the same measurement methods in the study setting. All the tests were completed by a laboratory technician unaware of patient groups.
