Table 4.
Patient crossover by diagnosis group: mean and median time between visits with similar diagnoses at Emory University Hospital (EUH) and Grady Memorial Hospital (GMH), based on direction of movement, and including the percentage of crossover patients receiving the same diagnosis at both hospitals.
| Time between visits | Crossover patients with diagnosis at both hospitals* | ||||||
| GMH→EUH | EUH→GMH | ||||||
| Mean time (days) | Median time (days) | Patients | Mean time (days) | Median time (days) | Patients | ||
| Non-traumatic subarachnoid hemorrhage (ntSAH) | 7 | 1 | 27 | 94 | 9 | 5 | 30/50 (60%) |
| Aneurysm (RYSM) | 34 | 3 | 11 | 86 | 9 | 5 | 15/43 (35%) |
| Pituitary related (PIT) | 255 | 92 | 11 | 247 | 36 | 3 | 12/30 (40%) |
| Arteriovenous malformation (AVM) | 35 | 5 | 6 | – | – | – | 6/12 (50%) |
| Shunt related (SH) | 334 | 309 | 4 | 520 | 231 | 4 | 7/23 (30%) |
| Cerebrospinal fluid leak (CSFlk) | 18 | 18 | 2 | – | – | – | 2/10 (20%) |
| Trauma (TR) | 20 | 7 | 5 | 660 | 702 | 5 | 9/52 (20%) |
| Traumatic subarachnoid hemorrhage (tSAH) | 269 | 269 | 2 | 702 | 702 | 1 | 1/21 (5%) |
*
Patient groups corresponding to movement patterns GMH→EUH and EUH→GMH are not disjoint due to bi-directional movement. The denominator corresponds to the count of crossover patients having the respective diagnosis at GMH, EUH, or both hospitals.
