Intervention(s)

After conducting four focus groups that include three nurses, a nephrologist and two administrative employees in four different regions of Colombia that asked about patient satisfaction, a scale for evaluating patients' satisfaction with the renal services ESUR-HD was created. The focus group defined certain dimensions with patient satisfaction that include overall satisfaction with the services, personnel at the unit, medications and supplies, facilities and processes, and phone contact. The ESUR-HD scale uses 44 items that are rated from one to five using a Likert scale. The final score is obtained by non-weighted sum of the score given to each item (higher scores reflect increased patient satisfaction). The survey takes 15 minutes to complete.

Participants who underwent hemodialysis at the clinics in 2013 are contacted by telephone to participate in the ESUR-HD scale. In order to measure convergent validity, the SDIALOR scale is simultaneously applied in a smaller subgroup of patients. The SDIALOR scale consists of seven domains (organisation of medical care, relationship between nephrologists and general practitioner, locational characteristics, accessibility, care provided by the health personnel, information provided by the doctor, problem solving, overall satisfaction). In order to test the reliability of the study a smaller sample of participants were re-surveyed two days after their initial assessment to consider the scale length. In order to establish the sensitivity to change, another smaller sample of participants are re-evaluated one month after using a new renal clinical within a hospital that includes remodelled spaces, waiting rooms, newer equipment, with more familiar, expert and dedicated healthcare staff.

Primary Outcome(s)

1. Convergent validity is assessed by comparing the correlation coefficients based on results of ESUR-HD and SDIALOR at baseline.
2. Test-retest reliability is measured using repeat surveys of ESUR-HD at baseline and day 2.
3. Sensitivity to change is assessed by comparing the ESUR- HD scale scores at baseline and one month after improved care conditions

Secondary Outcome(s)

No secondary outcome measures.
