A patient with an unknown allergy to suxamethonium gets booked for emergency laparotomy at 2am. The on-call anaesthesiologist has never met this patient. The paper chart is in another ward. The previous anaesthetic record from three months ago is filed somewhere in medical records.
When that information isn't retrievable at the moment of induction, the anaesthesiologist either makes a conservative drug choice and accepts the limitations, or takes a risk that doesn't need to be taken. The Anaesth History field in this template exists to break that specific information chain failure — a prior adverse reaction, a difficult intubation grade, a documented awareness event — making it searchable and available the moment the patient's name appears in the booking list.
The Gap Between Booking and Knife-to-Skin
A pre-operative assessment without retrievable documentation is an assessment that only lives in the anaesthesiologist's head. When they hand the case over to a colleague mid-list, when they're covering a colleague's list in a different hospital, when the case is postponed and returns six weeks later — the assessment starts from zero.
The structure here is an anaesthesiologist's working note, not an administrative form. Date, patient name, operation, surgeon, hospital — those are the identifiers. Medical History, Patient Medications, and Allergies are the clinical substrate. The Anaesthesia plan field is where the thought process is recorded: GA vs regional, airway plan, anticipated blood loss, specific intraoperative goals. Anaesthesia Follow is the intraoperative narrative. Outcome is the perioperative result — including any complications, unexpected events, or variations from plan.
What's critical is that the Labs and Reports field captures the actual investigation results — preoperative ECG, echo report, renal function, coagulation profile — as image attachments. Not a summary note about the labs. The actual results. Because the number a colleague mentions verbally and the number on a troponin report are two different levels of clinical certainty.
Where the System Earns Its Place
Three weeks after an uneventful Whipple procedure, the same patient returns for a complication drainage. The surgeon wants the same anaesthesiologist. The anaesthesiologist is in a different hospital. The covering consultant reviews the record: previous anaesthesia history — the RSI approach was noted due to impaired gastric emptying, total morphine consumption was high, the patient had significant postoperative nausea requiring ondansetron plus dexamethasone. That's not information available from the surgical notes.
The Outcome field is the one that gets ignored the most, and it's the one that matters most at six months. TIVA was chosen because of a documented malignant hyperthermia family history. The post-op pain score was 8 at four hours despite epidural analgesia. The patient was transferred to ITU for overnight monitoring. Those outcomes feed the anaesthesiologist's own quality audit, the departmental morbidity review, and the defence file if something later goes wrong.
Sorted by date, filtered by hospital, this becomes a longitudinal record of practice across institutions — the kind of data that a senior registrar preparing a fellowship portfolio can use directly, and that a consultant facing a GMC inquiry can present as evidence of consistent clinical documentation.
