  • Medication safety in frail residents: what the GP can do

    Giving a resident someone else’s medicines is one of the most preventable ways to cause serious harm in aged care, and it is still happening.

    Recent coronial findings have called for a national medication safety standard covering prescribing, dispensing and administration in residential aged care.

    In October the Aged Care Quality and Safety Commission followed with a clinical alert [1]. In the same bulletin, its Chief Clinical Advisor, geriatrician Dr Mandy Callary, wrote about frailty [2]. The two pieces belong together. A frail resident is exactly the person in whom a wrong-patient dose turns catastrophic, and the GP is often the person who wrote the chart the error was made against.

    This post is for GPs who visit residential aged care, and for those who take the after-hours call when something goes wrong.

    What went wrong

    The failure points behind wrong-patient errors are ordinary, which is why they are preventable.

    The Commission lists the contributing factors it sees [1]. Staff:

    • did not complete the six-rights checks (resident, medicine, dose, time, route, documentation)
    • were unfamiliar with the facility and its residents
    • were distracted mid-round
    • did not recognise psychotropics as high-risk medicines
    • did not escalate urgently once the error was found.

    Slow communication with families after an error adds to their distress.

    The coroner also noted a regulatory gap. The Commission confirmed there is no national medication safety standard for residential aged care. The existing Guiding Principles for medication management are non-prescriptive, and the strengthened Quality Standards do not specify the systems required. Victoria has since moved on its own: from 1 July 2026, only registered nurses may administer prescribed and regulated medicines in Victorian aged care homes.

    Why the frail resident has no margin

    A wrong-patient dose that a robust 60-year-old would sleep off can kill a frail 90-year-old, because frailty is a loss of physiological reserve.

    The Commission puts it plainly: frail older people are highly sensitive to adverse drug effects, and the risk compounds with polypharmacy and high-risk medicines [1]. Its alert singles out the drug-naïve resident. A first-ever dose of an antipsychotic, opioid or benzodiazepine can become catastrophic very quickly. Dr Callary’s blog cites Department of Health data that 99% of Australian aged care residents are frail [2].

    The mechanisms are familiar from the ward:

    • Pharmacokinetics. Lower GFR, often overestimated by creatinine in sarcopenic patients. Lower serum albumin, so more free drug. A shift toward fat mass, so lipophilic drugs accumulate.
    • Pharmacodynamics. Heightened CNS sensitivity, blunted baroreflexes, and impaired thermoregulation and swallow.
    • No tolerance. The resident has never had the drug, so there is no adaptation to sedation, respiratory depression or postural hypotension.
    • Cascade. Sedation leads to aspiration, a fall, a fracture or a long lie. Each is a second insult the resident cannot absorb.

    A first dose of an antipsychotic or opioid in a naïve, frail patient can cause profound sedation, hypotension and aspiration. These are the same risks behind the slow titration we use when starting such drugs deliberately.

    Frailty is a diagnosis, not a description

    Dr Callary’s central point is that frailty should be named and measured as a clinical condition, not shrugged off as “just old”. Once it is named, it reorganises the care plan around the person rather than around each disease in turn.

    The evidence base for doing this is modest but consistent. The Asia-Pacific Clinical Practice Guidelines [3] make three strong recommendations:

    1. Identify frailty with a validated tool.
    2. Prescribe physical activity with a resistance-training component.
    3. Deprescribe inappropriate or superfluous medicines.

    Their conditional recommendations are to look for reversible causes of fatigue, to investigate unintentional weight loss and consider protein and energy supplementation, and to replace vitamin D where it is deficient. The RACGP Silver Book recommends assessing frailty annually [4].

    Two tools suit general practice:

    • FRAIL scale. Five questions: Fatigue, Resistance (climbing a flight of stairs), Ambulation (walking a block), Illnesses (five or more) and Loss of weight (over 5% in a year). Scoring is 0 robust, 1–2 pre-frail, 3–5 frail. It takes about a minute and slots into the 75+ health assessment [5].
    • Clinical Frailty Scale. A 9-point pictorial judgement scale. It is quick and widely used in hospitals, but it is less reliable at separating frailty from disability [5], and it is not validated in people under 65.

    In residential care almost everyone screens positive, so the value of naming frailty shifts. It stops being a screening exercise and becomes a lens for prescribing, transfer decisions and goals-of-care conversations.

    What the GP can do

    The administration error happens on the nurse’s round. But the GP shapes how dangerous the trolley is, and is usually the first doctor called when it goes wrong.

    Before the error: make the chart safer

    • Deprescribe deliberately. Every medicine removed is one fewer to give to the wrong person. Review psychotropics, opioids, benzodiazepines, sulfonylureas and antihypertensives first, and use the residential medication management review (RMMR) pharmacist.
    • Keep high-risk medicines visible. Ask that S8s be packed separately from the dose administration aid, as the Guiding Principles recommend [1]. Ask that psychotropics sit on the facility’s psychotropic register with an indication and a review date.
    • Treat psychotropics as restrictive practice where they are. Make sure there is informed consent and a behaviour support plan, not a standing PRN.
    • Check the eNRMC. Look for a current photo and correct identifiers on each resident’s chart. Duplicate or mismatched profiles have caused deaths before.
    • Name frailty in the notes. A line such as “frail, CFS 7, no reserve” tells the after-hours doctor what a small error could do.

    After the error: the phone call

    The Commission’s position is unambiguous. When medicine has been given to the wrong person, seek immediate medical review in every case [1]. For the GP or deputising doctor taking that call:

    1. Get the facts. Which medicines, what doses, what time, and which ones the resident already takes. A drug-naïve resident receiving a high-risk drug is the red flag.
    2. Call Poisons Information on 13 11 26 while you assess. They will advise on expected toxicity and the observation period.
    3. Set a low threshold for transfer. Transfer is reasonable for clozapine and other antipsychotics, opioids, benzodiazepines, sulfonylureas, insulin, beta-blockers, calcium-channel blockers, digoxin and anticoagulants, especially if the resident is frail or the facility cannot provide close observation overnight.
    4. If they stay, be specific. Write a time-bound observation plan: GCS, respiratory rate, BP and BGL, with defined call-back triggers. Remember that some toxicity is delayed, such as sulfonylurea hypoglycaemia and sustained-release preparations.
    5. Document and disclose. Record the event and your advice, and support the facility’s open disclosure to the resident and family. SIRS reporting is the provider’s obligation, but confirm it is happening.

    Telehealth makes step 1 harder. If the staff member cannot say clearly what was given, treat it as the worst plausible case.

    The point

    The system failures belong to providers, and national standards may follow. Our part is quieter: shorter charts, visible high-risk drugs, frailty written down, and a firm answer at 2 am when a nurse rings to say the wrong tablets went to the wrong room.
