Table 5.
ED visit and hospitalization outcomes associated with eVisits and secure messages.
| Outcome count associated with secure message n=6430 (%) | Outcome count associated with eVisit* n=892 (%) | Fisher's exact p value | OR (95% CI) eVisit to secure message | |
|---|---|---|---|---|
| ED visit or hospitalization count | ||||
| Unique ED visits within 7 days after message | 56 (0.87) | 9 (1.0) | 0.70 | 1.2 (0.6 to 2.4) |
| Consensus unique ED visits actually related to any previous message | 28 (0.44) | 7 (0.78) | 0.19 | 1.8 (0.8 to 4.2) |
| Unique hospitalization within 7 days after message | 17 (0.26) | 3 (0.34) | 0.73 | 1.3 (0.4 to 4.4) |
| Consensus unique hospitalizations actually related to any previous message | 6 (0.09) | 2 (0.22) | 0.25 | 2.4 (0.5 to 12.0) |
| Message count† (multiple messages per outcome possible) | ||||
| Unique messages within 7 days before ED visit | 85 (1.3) | 11 (1.2) | 0.99 | 0.9 (0.5 to 1.7) |
| Consensus unique messages determined actually related to ED diagnosis | 37 (0.6) | 8 (0.9) | 0.25 | 1.6 (0.7 to 3.4) |
| Unique messages within 7 days before hospitalization | 31 (0.48) | 3 (0.34) | 0.79 | 0.70 (0.2 to 2.3) |
| Consensus unique messages determined actually related to hospitalization diagnosis | 6 (0.09) | 2 (0. 22) | 0.25 | 2.4 (0.5 to 12.0) |
Message counts for those outcomes (multiple messages for some hospitalization or ED visit outcomes).
*For multiple previous messages, outcome was attributed to eVisit column if at least one eVisit was generated regardless of additional number of associated secure messages.
†The 108 secure messages and eVisits we reviewed are fewer than the total messages in this table because several unique messages were counted both as associated with an ED visit and a hospitalization (eg, message from a patient who went to the ED and was subsequently hospitalized).
