Table 4.
Number of hypertension-related polyclinic visits.
| Time point | UC group (N = 115) | TI group (N = 103) | p value | Difference-in-differences |
|---|---|---|---|---|
| Hypertension-related visit: Tele-consultation (by nurses only) | ||||
| 6 months before intervention | 0 | 0 | 0.29† | |
| 6 months during intervention | 0.2 | 1.7 | 0.01* | |
| Difference | 0.2 | 1.7 | 1.5† | |
| p value | <0.01**† | <0.01**† | <0.01**† | |
| Hypertension-related visit: Face-to-face visit (with physician and/or nurse) | ||||
| 6 months before intervention | 2.5 | 2.5 | 0.95 | |
| 6 months during intervention | 3.2 | 3.6 | 0.11 | |
| Difference | 0.7 | 1.1 | 0.4 | |
| p value | <0.01** | <0.01** | 0.27 | |
| Hypertension-related visit: Both | ||||
| 6 months before intervention | 2.5 | 2.5 | 0.99 | |
| 6 months during intervention | 3.3 | 5.2 | <0.01** | |
| Difference | 0.8 | 2.7 | 1.9 | |
| p value | <0.01** | <0.01** | <0.01** | |
All p values were generated from Poisson regression, except for those labeled with the symbol “†” which were generated by transformed visit using log(visit + 1) with the standard t-test. TI: telemonitoring intervention; UC: usual care.
