Table 3 Risk reduction on emergency department (ED) visits and hospital readmission (RA) visits due to scopolamine patch use among children with drooling
Emergency department visits (ED): | |
Rate of ED visits due to drooling before scopolamine patch use (CER) % | 33.0 |
Rate of ED visits due to drooling after scopolamine patch use (EER) % | 5.4 |
ARR on ED visits %= CER - EER = 33.0–5.4 | 27.6 (95%CI:9.4–45.6, p < 0.001)) |
RRR on ER visits % = (CER – EER)/CER = (33.0–5.4)/33.0 | 86.0 |
Relative risk (RR) = EER/CER = 5.4/33.0 | 0.16 |
Readmission visits (RA): | |
Rate of RA visits due to drooling before scopolamine patch use (CER) % | 44.4 |
Rate of RA visits due to drooling after scopolamine patch use (EER) % | 8.7 |
ARR on RA visits %= CER - EER = 44.4–8.7 | 35.7(95% CI: 15.7–55.7, p < 0.001) |
RRR on RA visits %= (CER – EER)/CER = (44.4–8.7)/44.4 | 67.1 |
Relative risk (RR) = EER/CER = 8.7/44.4 | 0.20 |
