Descriptive statistics for survival analysis, by outcome
| Outcome | A&E presentation | SMI admission | ACSC admission |
| N individuals | 4446 | 5158 | 5158 |
| Mean years observed | 1.50 | 2.47 | 2.56 |
| N with outcome (% of sample) | 2213 (50%) | 562 (11%) | 528 (10%) |
| Mean years observed to outcome* | 1.08 | 1.20 | 1.68 |
| N (% of events) with outcome occurring: | |||
| within 12 months of CP (current CP) | 756 (36%) | 200 (35%) | 171 (32%) |
| >12 months since CP (expired CP) | 250 (11%) | 77 (14%) | 109 (21%) |
| with no CP | 1207 (54%) | 285 (51%) | 248 (47%) |
| within 12 months of AR (current AR) | 1024 (46%) | 263 (47%) | 301 (57%) |
| with no current annual in last 12 months | 1189 (54%) | 299 (53%) | 227 (43%) |
The period of observation is shorter in the outcome-specific samples than the full study observation period because the patient exits observation once the first outcome event occurs.
A&E presentation: Presentation of any cause to the accident and emergency department.
SMI admission: Inpatient admission with a primary diagnosis of serious mental illness (ICD-10 codes F20-F31).
ACSC admission: Inpatient admission with a diagnosis of an ambulatory care-sensitive condition (see online supplementary table 1 for a list of conditions).
*Mean years observed from diagnosis to outcome for those who experienced the outcome.
AR, annual review of physical health; CP, care plan.
