| Factors | Readiness assessed* (n=432) | Readiness not assessed* (n=294) | p Value† |
|---|---|---|---|
| LP outcomes | |||
| Success on first attempt (primary outcome) | 174 (40.0) | 103 (35.0) | NS |
| Success on any attempt | 203 (47.0) | 127 (43.2) | NS |
| Number of attempts, median (IQR) | 1 (1–2) | 1 (1–2) | NS |
| Process outcomes | |||
| Topical analgesia used | 83 (19.2) | 38 (12.9) | 0.03 |
| Early-stylet removal technique used | 243 (56.3) | 133 (45.2) | <0.001 |
| Family member presence | 112 (25.9) | 61 (20.7) | NS |
| Attending supervision‡ | 195 (45.1) | 86 (29.3) | <0.001 |
In all 726 patients who had an LP, we looked for additional factors associated with success including attending supervision, family member presence and analgesia use. No statistically significant associations were found.
