SP Notes

FANZCA Part II Notes

ANZCA Professional Document PS51 – 2009

Medication error = a medication given in mistake that may or may not have an adverse clinical outcome.

- drug error incidence = 1/135 anaesthesia

- can cause significant harm to patients

- need to recognise and adopt techniques to minimise such events

PREDISPOSING FACTORS

ICU factors

- complex environment: high stress, high turnover, high nursing turnover

- emergency admissions

- multiple care providers

- storage area

- mis-communication when patients transferred from wards/inter-hospital

Medication factors

- packaging: often many drugs have similar packaging (narcotics)

- often infusions based

- patient on multiple infusions

Patient factors

- severity of illness

- time critical drug administration

- extremes of age

- prolonged hospitalisation

- sedation

MANAGEMENT

General

- aim = give correct drug, to correct patient by correct route and record information accurately

- we should know physiology, pharmacology and how to manage complications

- take thorough drug history

- drugs administered by non-medical personnel should have medical supervision and a written order

- write legibly

- good communication

- minimise distraction when drawing up

- adequate light

- bar code technology

- medication reconciliation

- avoid fatigue and cumulative working hours

- minimise interruptions and distractions

- adequate staffing

- Pharmacist participation

- quality assurance as a part of education program

- decrease nurse to patient ratio

- AIMS ICU (Australasian Incident Monitoring Study in ICU)

Purchasing

- purchasing and inventory should minimise drug error

- avoidance of look-a-like packaging

- changes to packaging must be widely communicated

- stocking of different concentrations should be avoided

- avoid need for dilution (pre-diluted)

Storage (workspace)

- tidy

- organised

- standardised

- emergency drug drawer

- look-alike ampoules -> store apart

- store in original packaging prior to drawing up

- appropriate trays

Labels

- labels should have agreed and clear writing

- pre-printed labels should be colour coded by drug class

- if labels not available -> permanent marker pen

Drawing up and checking drugs prior to Administration

- read label (check name and dose)

- regular checking for expired drugs

- label syringes appropriately

- draw up one drug @ a time and label

- if interrupted when drawing up a drug -> discard

- before administering check drug and dose with a second person or an automated device

- any one ampoule should be administered to only one patient

Storage

- time interval from drawing up and administering should be short

- store logically and orderly

- drugs with different routes should not be stored together

- emergency drugs should only be drawn up where there is time critical response -> otherwise can be given inadvertently.

Maintenance of Accurate Records

- keep accurate records

- keep ampoules so drugs can be reconciled if problem develops

- discard ampoules once finished with

Infusion Drugs

- infusion pumps and syringe drivers should be standardised

- label patient end of the infusion

- caution of one way valves to avoid siphoning of infused drug
