CKD performance outcome measures for wave I and wave II practices
| Performance measure | Wave I | Wave II | ||||
|---|---|---|---|---|---|---|
| Pre-intervention period | Post-intervention period | p value* | Pre-intervention period | Post-intervention period | p value* | |
| If eGFR <60 | N = 374 | N = 660 | ||||
| ACE or ARB prescribed: n (%) | 232 (63%) | 255 (69%) | 0.002 | 354 (55%) | 407 (63%) | <0.001 |
| Taking NSAIDs: n (%) | 25 (7%) | 18 (5%) | 0.10 | 51 (8%) | 45 (7%) | 0.44 |
| A1c testing performed: n (%) | 288 (77%) | 297 (79%) | 0.25 | 492 (89%) | 487 (88%) | 0.65 |
| Urine microalbumin test performed: n (%) | 158 (42%) | 175 (47%) | 0.16 | NA | NA | NA |
| LDL test performed: n (%) | 309 (83%) | 305 (82%) | 0.75 | NA | NA | NA |
| A1c test results: Mean (SD) | 7.1% (1.4) | 7.2% (1.5) | 0.78 | 7.4% (1.6) | 7.3% (1.5) | 0.07 |
| Systolic BP measure (mmHg): mean (SD) | 132.5 (16.3) | 132.8 (16.0) | 0.72 | 132.0 (15.9) | 131.4 (14.9) | 0.39 |
| Diastolic BP measure (mmHg): mean (SD) | 72.8 (9.1) | 72.7 (9.0) | 0.93 | 72.0 (9.4) | 71.7 (8.5) | 0.48 |
| LDL test result (mg/dl): mean (SD) | 89.8 (36.6) | 90.2 (32.8) | 0.84 | 96.3 (38.1) | 92.0 (34.5) | 0.004 |
| If eGFR <45 | N = 138 | N = 233 | ||||
| Hemoglobin test performed: n (%) | 84 (61%) | 100 (72%) | 0.02 | NA | NA | NA |
| Vitamin D testing (or supplement): n (%) | 51 (37%) | 83 (60%) | <0.001 | 87 (37%) | 132 (57%) | <0.001 |
SD standard deviation, NA not applicable because it was an annual recommendation and in wave II, the post-intervention period was only 9 months.
*McNemar’s test was used to generate p values for categorical-scaled outcomes and the paired t test for continuous-scaled outcome measures.
