UltraCare/Evidence

Clinical evidence & method

How every number is produced.

UltraCare turns the values a team charts into scores, signals and estimates — transparently. Every figure is traceable to its inputs and to a published method. Nothing here is a black box, and nothing decides for the clinician. Decision support, not decision making.

The severity scores

Four established scores, computed deterministically from charted values — the same maths exposed in the free calculators, which are the interactive proof.

Deterioration signals

Today's deterioration signals are rule-based trend deltas on charted values — transparent thresholds applied to the direction and rate of change (for example, a rising lactate or a falling MAP over the last hours). They are not a predictive machine-learning model. A validated ML deterioration predictor is Phase 2, pending pilot data and ICMR ethics approval — it is labelled as roadmap, never implied to be live.

Outcome estimates

Mortality, length-of-stay and vent-free-day figures are shown as reference ranges from published cohorts — context to interpret a score, never a patient-specific prediction. Precise, individualised percentages (for example an APACHE II predicted mortality) require diagnosis-specific coefficients and are deliberately not fabricated.

Handover & safety frameworks

  • I-PASS — a structured sign-out (Illness severity · Patient summary · Action list · Situation awareness & contingency · Synthesis by receiver, with read-back). Origin: Starmer et al., NEJM 2014.
  • FAST HUGS BID — a daily ICU safety sweep (Feeding, Analgesia, Sedation, Thromboprophylaxis, Head-up, Ulcer prophylaxis, Glycaemic control, Spontaneous breathing, Bowel care, Indwelling lines, De-escalation). Origin of the mnemonic: Vincent, Crit Care Med 2005; "BID" is a later bedside extension.

Transparent by design, admission to discharge.

Every score, signal and estimate is shown with the inputs it came from. The intensivist stays in the loop and makes the call. Try the free calculators, or see it in the workspace.
