Stage of change, knowledge, and other factors by modality decision being made
| Parameter (n=55) | Modality Decision Made | P Value | |
|---|---|---|---|
| No (n=21) | Yes (n=34) | ||
| Age (yr) | 62 (10.8) | 56 (10.9) | 0.13 |
| Dialysis knowledge scorea | 0.2 (1.0) | 1.4 (1.2) | <0.01 |
| eGFR (ml/min per 1.73 m2) | 16.8 (3.5) | 13.9 (4.5) | 0.04 |
| Doctors explaining modality options | 42.9% | 75.8% | 0.02 |
| Visiting a dialysis center | 29.4% | 36.8% | 0.23 |
| Health literacy scorea | 15.0 (4.0) | 15.0 (3.0) | >0.99 |
| Lifestyle barrier scorea | 0.9 (0.5) | 1.1 (0.9) | 0.85 |
| Provider connection | −0.026 | 0.16 | 0.05 |
| Duration of nephrologist care (yr)a | 2.0 (4.5) | 2.3 (5.0) | 0.80 |
| Annual household income (US$)a | 17,500 (12,500) | 17,500 (12,500) | 0.48 |
| Travel time to home dialysis unita | 3.0 (1.0) | 3.0 (1.0) | 0.02 |
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. 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 two scores represent composite scores, whereas travel time is a score for that single factor, and all scores are from factor analyses. Health literacy score was derived using the scale reported by Wallace et al. (28). 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.
