Neutropenia, ICU admission, presentation with severe sepsis or shock, and BSI due to Pseudomonas aeruginosa were associated with significant increased 14- and 30-day mortality.
First admission or presentation is unlikely to equate to first episode because of duration of untreated illness.
The patients' age, sex, time of presentation (by day of week and time of day), diagnosis (at discharge from the ED and from hospital if admitted) and outcome of their time in the hospital system, including admission, re-presentations and mortality, were extracted.
In both the hospital and ambulatory clinics, care sought for the current illness episode prior to hospital admission or presentation to the ambulatory clinic was reported by the patient or caregiver, along with any medicines taken prior to admission or presentation.
Severe thrombotic thrombocytopenic purpura (TTP) is often diagnosed in the ICU or necessitates an ICU admission on presentation.
Attendances on weekdays or in the out-of-hours period were more likely to produce admissions than presentations at weekends, but the OR was less than 1.5.
If the likelihood of admission after presentation to hospital with self harm differs by age, sex, and diagnosis then this will bias our risk estimates.
Demographic data, neurological status at admission, clinical presentation, predisposing factors, anatomical location, number of lesions, surgical techniques, organisms cultured, and the neurological outcome were collected from the electronic hospital data (Table 1).
Such variables as age, gender, Glasgow Coma Scale (GCS) score at admission, clinical presentation, location, number of lesions, predisposing factors, mechanism of infection, aetiological agent, and therapy were analysed independently.
