Why a Closed Loop Solution?
We are all familiar with closed-loop systems, even if we do not call them by that name. In fact, we trust our lives with some of these systems. A shortlist of some common control systems includes:
- Cruise control on our cars
- Industrial process control
There are many benefits of closed-loop systems including safety, effectiveness and efficiency. Importantly, they are designed to manage complex, uncertain systems. Very relevant in clinical situations, closed-loop systems will become “force multipliers”: allowing time-constrained professionals to focus on the important aspects of care requiring human expertise and caring.
Closed-loop systems in healthcare will be integral components of autonomous care systems.
There are specific challenges for closed-loop control in critical care, which we are addressing in the CLIP solution. These are all soluble, and well worth solving to improve patient outcomes:
- Quality, reliability and information content of input signals
- Choice of target variables
- Selection of target variables and values
- Robust controller algorithms that cope with physiological nonlinearity and variability, and adjust to changing patient state
- “Although smart pumps have made IV infusions safer than the days of gravity drips and dial-a-flow, 23% of surveyed organizations still reported serious medication incidents in the past 24 months while using their smart pumps— 60% of those while compliant with drug libraries.”
