Exploring Life Experience and Lifestyle Intervention Program Among Patients With Chronic Kidney Disease: A Longitudinal Study

to compare the effectiveness of tailored TTM-based interventions (intervention group) compared to usual care (control group) on biomarkers of kidney function, physical indicators, adoption of health-promoting lifestyle behaviors, kidney disease knowledge, perceived self-efficacy, perceived benefits and barriers to physical activity changes, and quality of life among patients with early-stage CKD over a 30 month period.

Studieoversikt

Detaljert beskrivelse

A thirty-month clinical trial (ClinicalTrials.gov registration NCT01194518) was conducted from October 2010 through October 2013. The CONSORT checklist (Schulz et al., 2010) guided the study. Data were collected at baseline and at 6, 12, 18, 24, and 30 months post-intervention.

Participants and Setting After obtaining approval to conduct the study from the Institutional Review Board, the nephrology case managers from the outpatient clinics of two medical centers in southern Taiwan were contacted and asked to refer patients to the study. Participants were included if they were at least 20 years old, diagnosed with stages 1 to 3 CKD, spoke Mandarin, and could be followed up every 6 months when they returned for an outpatient visit. Patients who were unable to participate in moderate exercise, unable to verbalize that they understood the study, or were already enrolled in another program were excluded. Upon obtaining written informed consent subjects were randomly assigned to the control or intervention group at a ratio of 1 to 1 using paper ballots.

The Bureau of National Health Insurance (BNHI) in Taiwan launched the CKD care program for pre-ESRD care which suggested that CKD management and education depended on the stage of CKD (Chen et al., 2011). In addition, Taiwan established a medical system protocol to standardize and regulate pre-ESRD care with all medical expenditures covered by the National Health Insurance (NHI). Therefore, patients receive regular follow-ups as nephrology outpatients with the nephrology case managers providing usual care.

Eksperimentell: Intervention group
Intervention groups completed the stage-of-change and readiness-to-change assessments. Intervention groups were provided tailored interventions based on the premise that patient response to physical activity in stages for lifestyle counseling from baseline, 6, 12,18 24, and 30 months.
The tailored intervention made use of the 10 processes of change, important guides for developing intervention programs, which have received the most empirical support to date. The 10 processes include consciousness raising, dramatic relief, self-reevaluation, environmental reevaluation, self-liberation, social liberation, counterconditioning, stimulus control, reinforcement management, and helping relations. The different tailored interventions were based on the processes of change matched to the patient's stage of change, providing strategies that may be especially helpful to patients. According to the Lenio analysis of the TTM model of behavior change, the first five processes are used in the early stages, and the last five are used in the later stages.

The checklist consists of 20 items including three domains: renal function protection (11 items), knowledge of Chinese herbal medicine related to renal function (5 items), and diet with CKD (4 items). Item responses were "true" or "false." Each item is scored with 5 points for each correct answer. The total scores for the checklist range from 0-100. Higher scores indicate higher knowledge of renal function protection.

Using a 5-point Likert scale from 1 "not satisfied at all" to 5 "extremely satisfied", higher scores indicate a better QOL. Each domain's score ranged from 4 to 20, which was calculated by multiplying the average of the scores of all items in the domain by four.
