In the case of the anticipated deteriorations, the proposed AFTC system selects the controller parameters from the bank of control system parameters, according to the current health condition; while in the case of the unanticipated deteriorations, the controller parameters will be determined through the optimization process.
The proposed FDI system provides the possibility of dealing with the unanticipated or unknown deteriorations.
The first few days of hospitalisation is a period in which clinical deterioration (eg, unanticipated ICU admission, death) frequently occurs, either despite adequate care or due to inadequate clinical care.
We hypothesise that older patients with delirium during early hospitalisation are at an increased risk for clinical deterioration (ie, unanticipated ICU admission and/or in-hospital death) and decline in discharge status, defined as discharge to higher level of care, hospice or death.
In this paper, an Active Fault Tolerant Control AFTCC) system with self-enrichment capability is proposed to deal with both the anticipated and unanticipated gas-path performance deteriorations in the industrial gas turbine engines.
(1) Clinical deterioration, defined as unanticipated intensive care unit (ICU) admission or in-hospital death (primary outcome); (2) decline in discharge status, defined as discharge to higher level of care, hospice or in-hospital death.
After adjusting for age and REMS, delirium within the first 3 days of hospitalisation remained significantly associated with clinical deterioration, defined as unanticipated ICU admission or in-hospital death (adjusted OR 8.07 (95% CI 1.91 to 34.14); p=0.005; figure 2, see online supplementary table S1).
Fatigue cracks, as a structural deterioration mechanism, may lead to unanticipated out of service of naval ships.
Many hospitalised patients suffering adverse events (for example, in-hospital cardiac arrest, unanticipated ICU admission or death) exhibit physiological deterioration in the period before the event [ 48- 50].
