Ratio and Percentage of Burn Survivors Who Were Dissatisfied with Sleep Stratified by Burn Size
| Months Since Burn | All | TBSA Burned <20% | TBSA Burned ≥20% | P |
|---|---|---|---|---|
| 0 to ≤6 | 56/172 (33%) | 47/149 (32%) | 9/21 (43%) | .30 |
| >6 to ≤12 | 13/59 (22%) | 4/43 (9%) | 8/14 (57%) | <.0001 |
| >12 to ≤36 | 12/52 (23%) | 5/50 (10%) | 8/21 (38%) | .0148 |
| All | 82/302 (27%) | 56/242 (23%) | 25/56 (45%) | .0011 |
The unit of analysis was survey record, rather than unique patient.
In each cell, the ratio is the number of surveys that showed dissatisfaction with sleep divided by the total number of surveys for that cell.
Overall, 35 of 249 (14.1%) survey records by the age-matched nonburned reference group had sleep dissatisfaction, compared with 82 of 302 (27%) shown in the table for burned sample.
P values were derived from χ2 or Fisher’s exact test of two proportions, whichever was appropriate.
