Table 1 Stratification of healthcare facilities
Number of transfers (during the sample period) | Representation of total number of transfers during entire study period | Ideal relative number of facilities to be sampled (out of 10) | Total number of facilities in sampling frame | Number of teaching facilities to be sampled | Number of community facilities to be sampled | Number of nursing homes/long term care facilities to be sampled |
|---|---|---|---|---|---|---|
Large volume senders (more than 1,000 patient transfers during the sample period) | 50% | 5 | 20 | 2 | 2 | 0* |
Medium volume senders (between 400 and 999 patient transfers during the sample period) | 21% | 2 | 11 | 1 | 1 | 1 |
Small volume senders (between 1 and 399 transfers during the sample period) | 29% | 3 | 152 | 1 | 1 | 1 |
