Pre Anaesthesia Assessment

A UK NHS-aligned, clinician-driven pre-operative assessment that records objective findings (history, examination, vitals, laboratory results, imaging) and computes an ASA Physical Status grade (I–VI), a composite perioperative risk level, and a set of safety-critical flags. The output is a signed clinician report with an anaesthesia plan suitable for the pre-operative record.

This form is the clinician counterpart to the patient self-report pre-operative questionnaire Pre Operative Assessment By Patient: completed by an anaesthetist, surgeon, pre-op assessment nurse, or perioperative physician rather than by the patient. It is aligned with CPOC's Preoperative Assessment and Optimization for Adult Surgery (2021) and the Geeky Medics Anaesthetic Pre-operative Assessment OSCE Guide, and supports shared decision-making under the Montgomery consent standard.

Scoring

Primary instrument: ASA Physical Status (I–VI), with clinician override + reason. Secondary instruments: Mallampati airway class (I–IV), RCRI (0–6), STOP-BANG (0–8), Clinical Frailty Scale (1–9), Duke Activity Status Index (DASI), ECOG performance status. Composite perioperative risk (Low/Moderate/High/Critical) is driven by the worst-band finding across instruments (max-grade algorithm).

Relationship to nearly-identical assessments in this collection

This assessment's description and scoring are effectively the same as Pre Operative Assessment By Clinician and overlap substantially with Anesthesiology Assessment — all three are clinician-completed, ASA-grade-driven, composite-risk pre-operative assessments in this source collection. Treat them as near-synonymous variants unless a specific context distinguishes them (e.g. a difference in which secondary instruments are included), and check the source repository directly if the exact distinction matters for a given task.

Common pitfalls

• Assuming this is meaningfully distinct from the other two similar pre-op assessments in this catalog — verify against the actual source content for the task at hand rather than guessing which specific variant a request means.
• Using a stale assessment for surgical clearance — physiological status can change between assessment and surgery date; reassess after a meaningful time gap or clinical change.
• Skipping senior review at the High/Critical composite-risk threshold — the banding exists specifically to trigger escalation.
