Knowledge score, stress, and modality decision made by stage of change
| Parameter (n=55) | Stage of Change | P Value | |
|---|---|---|---|
| Thinking (n=36) | Acting (n=19) | ||
| Dialysis knowledge scorea | 0.8 (1.0) | 1.4 (1.2) | 0.003 |
| eGFR (ml/min per 1.73 m2) | 15.5 (3.6) | 14.2 (5.5) | 0.41 |
| Doctors explaining modality options | 51.4% | 84.2% | 0.02 |
| Visiting a dialysis center | 29.4% | 36.8% | 0.76 |
| Took educational reading material | 72.7% | 77.8% | 0.75 |
| Effect of travel time to home dialysis unit on dialysis decision makinga | 3.0 (2.0) | 3.0 (1.0) | 0.08 |
| Dialysis modality decision made | 47.2% | 89.5% | 0.003 |
| Lifestyle barrier scorea | 1.14 (0.71) | 0.64 (0.57) | 0.001 |
| CKD self-efficacy score | 3.6 (0.5) | 3.7 (0.8) | 0.65 |
| Provider connection | −0.17 | 0.32 | 0.02 |
| Duration of nephrologist care (yr)a | 2.0 (5.0) | 4.0 (5.0) | 0.16 |
Dialysis knowledge score is the combined knowledge of all RRTs (higher score equates to more knowledge). Lifestyle barrier score is higher if more barriers are reported to making a dialysis decision. CKD self-efficacy is a set of questions designed to gauge a person’s confidence in making decisions about and managing their CKD (higher score means higher efficacy). Provider connection is the factor score from the factor analyses listed. Travel time refers to the time taken to travel between a patient’s home and the closest dialysis unit offering home dialysis being a factor in the modality decision. The first three scores represent composite scores, whereas travel time is a score for that single factor, and all scores are from factor analyses. Proportions were reported for categorical variables, means (SDs) were reported for normally distributed numerical variables, and medians (interquartile ranges) were reported for non-normally distributed numerical variables.
Variables for which medians (interquartile ranges) were calculated.
