Patient characteristics, ICU-specific supports, complications, and outcomes of persistent critical illness.

Objectives: The primary objective was to identify the proportion of patients on mechanical ventilation (MV) beyond day 10, the recently defined time of onset of Persistent Critical Illness (PerCI). The secondary objective was to identify underlying diagnoses, intensive care unit (ICU) based therapies, relevant complications, and outcomes of patients with PerCI.

Subjects: 100 PerCI patients and 100 age, sex, mechanical ventilation for >24 h, acute physiology and chronic health score (APACHE III) and co-morbidity score-matched controls.

Medical health care utilization cost of patients presenting with psychogenic nonepileptic seizures.

Objective: To investigate the health care utilization cost of patients presenting with psychogenic nonepileptic seizures (PNES) to a tertiary hospital in Australia.

Methods: This is a retrospective analysis of adult patients with PNES based on video-electroencephalographic confirmation over a 5-year period. We used an itemized list to collect detailed health care utilization data.

Optimal duration of video-electroencephalographic monitoring to capture seizures.

We aimed to find the optimal duration of long-term video-electroencephalographic monitoring (VEM) to capture seizures in patients with epileptic seizures (ES) and psychogenic non-epileptic seizures (PNES) by evaluating the time to first clinical event and the diagnostic yield of clinical events and positive cases in each day of VEM. Patients aged ⩾18years who underwent VEM from May 2009 to June 2014 were studied retrospectively. Demographic, clinical and VEM data (including total monitoring length, type and time to first event, total number of ES/PNES) were collected.
