Unadjusted Comparison of Baseline and Follow-up Blood Pressure Readings and A1c Levels (Mean, SD)
| Baseline | Follow-up | Difference | ||||
|---|---|---|---|---|---|---|
| PCP only | PCP + PharmD | PCP only | PCP + PharmD | PCP only | PCP + PharmD | |
| (N = 835) | (N = 236) | (N = 835) | (N = 236) | |||
| Systolic blood pressure* | 156.6 (15.3) | 161.3 (18.7)† | 140.3 (19.5) | 145.2 (21.6)† | −16.2 (21.8) | −16.1 (24.2) |
| (N = 642) | (N = 186) | (N = 642) | (N = 186) | |||
| Diastolic blood pressure* | 96.5 (7.0) | 98.1 (8.6)† | 87.0 (10.7) | 87.0 (11.1) | −9.5 (11.2) | −11.1 (12.8) |
| (N = 160) | (N = 136) | (N = 160) | (N = 136) | |||
| Hemoglobin A1c* | 9.3 (1.7) | 10.2 (2.2)† | 8.4 (1.6) | 9.3 (2.3)† | −0.9 (1.9) | −0.9 (2.4) |
*
Systolic blood pressure ranges: PCP 140 to 241 vs. PCP + PharmD 140 to 231; diastolic blood pressure ranges PCP 90 to 142 vs PCP + PharmD 90 to 149; A1c 8 to 15 both study groups.
†
P < 0.05 comparing group differences at baseline and follow-up; however, the difference-in-difference analysis shows no significant group difference in change in blood pressure or A1c over time.
