Abstract
A method for adaptively scheduling non-invasive blood pressure measurement time intervals based on using a risk model to compute a risk of a patient suffering a pre-defined one or more adverse clinical events, for example within a pre-defined time window, and also based on a clinician risk assessment for a patient.
Claims15
A computer-implemented method comprising:
- receiving biological measurement data for a patient;
- applying a patient risk model to compute a risk parameter, p, indicative of a risk level of at least one pre-defined adverse clinical event, wherein at least one input to the model is the biological measurement data;
- obtaining a clinician-defined patient risk parameter, A, indicative of an assessment by a clinician of the risk level for the at least one pre-defined adverse clinical event;
- computing a measurement time interval, T, for successive non-invasive blood pressure measurements of the patient based on A, and p, and in accordance with the relationship
- T
- ∝
- A
- p
- α
- where α is pre-defined parameter;
- and
- controlling a non-invasive blood pressure measurement apparatus to acquire blood pressure measurements at a frequency defined by the determined time interval, T.

A processing unit, comprising:
- an input/output;
- and
- one or more processors adapted to:
- receive at the input/output biological measurement data for a patient;
- apply a patient risk model to compute a risk parameter, p, indicative of a risk level of at least one pre-defined adverse clinical event, wherein at least one input to the model is the biological measurement data;
- obtain a clinician-defined patient risk parameter, A, indicative of an assessment by a clinician of the risk level for the at least one pre-defined adverse clinical event;
- compute a measurement time interval, T, for successive non-invasive blood pressure measurements of the patient based on A, and p, and in accordance with the relationship
- T
- ∝
- A
- p
- α
- where α is pre-defined parameter;
- and
- control, via generating control signals for output at the input/output, a non-invasive blood pressure measurement apparatus to acquire blood pressure measurements at a frequency defined by the determined time interval, T.
