Improving Medication Reconciliation at Discharge: Tools From the Las Vegas Meeting

Medication reconciliation at discharge is a practical patient-safety task: creating the most accurate possible list of medicines, explaining every change, and ensuring that the list reaches the people who will act on it. The Hospital Medicine 2017 meeting in Las Vegas brought together hospitalists and other healthcare professionals to examine this process alongside broader issues in clinical practice, research, education and care transitions.

Although the meeting took place in 2017, its core lessons remain relevant in Australian hospitals. A patient leaving a ward in Sydney, Melbourne or a regional town may see a different general practitioner, collect medicines from a community pharmacy, rely on a family carer, or manage several prescriptions through the Pharmaceutical Benefits Scheme. A reliable discharge workflow must connect those everyday realities with prescribing systems, clinical judgement and clear communication.

What Reconciliation Must Achieve

Medication reconciliation is more than printing a discharge medicine list. It compares the medicines a patient was taking before admission with those prescribed during the hospital stay and those intended after discharge. Each difference should have a reason: a medicine may have been stopped, restarted, substituted, reduced, increased or temporarily withheld.

The process usually begins with the best possible medication history. Staff may need to consult the patient, family, carers, general practitioner, community pharmacist, previous records, dose administration aids and medicine containers. In Australia, the list may also be checked against My Health Record where information is available, while recognising that records can be incomplete, outdated or missing recent over-the-counter products.

The final list should answer three questions in plain language: what should the patient take, what should they stop, and what has changed? It should include medicine name, purpose, dose, route, timing, duration and monitoring requirements. “Resume usual medicines” is unsafe when the patient needs to know which medicines were deliberately withheld or altered.

Tools That Make The Process Reliable

A structured reconciliation form reduces dependence on memory. Useful fields include pre-admission medicine, inpatient order, discharge decision, reason for change, prescriber initials and follow-up action. Electronic systems can provide prompts for high-risk medicines, duplicate therapy, renal dosing and omitted long-term treatment, but an alert should support clinical reasoning rather than replace it.

A three-column format is especially useful at the point of discharge: medicines before admission, medicines during admission and medicines after discharge. A fourth field for “reason and action” helps expose unresolved discrepancies. For example, a patient taking warfarin before admission may leave hospital on a different anticoagulant, with a documented indication, intended duration, pathology plan and responsible clinician.

Teach-back is another low-cost tool. Rather than asking whether the patient understands, the clinician asks the patient or carer to describe how the medicines will be taken at home. This can reveal confusion about lunchtime doses, tapering instructions, inhaler technique or the difference between regular and “when required” treatment. Written instructions should use the patient’s preferred language and account for vision, dexterity, health literacy and cognitive impairment.

The educational resources associated with Hospital Medicine 2017 are useful for viewing reconciliation as a team activity rather than a task delegated to whichever clinician happens to complete the discharge paperwork. Doctors, pharmacists, nurses, allied health professionals and ward clerks each see different parts of the transition.

Assigning Responsibility Across The Transition

A process fails when every professional assumes someone else has checked the medicines. The admitting clinician should establish the initial history, inpatient teams should update it as treatment changes, and the discharging clinician should confirm the final regimen. A pharmacist can resolve discrepancies, assess interactions and provide counselling, but pharmacist involvement does not remove the prescriber’s responsibility for the discharge orders.

The handover must reach the next care setting promptly. The patient should leave with a reconciled list, a discharge summary and prescriptions that match. The general practitioner needs the clinical reasons for medication changes, pending tests and follow-up requirements. The community pharmacist needs enough detail to dispense safely, particularly where a brand switch, dose taper, staged supply or authority prescription is involved.

Australian hospitals should also consider the practical timing of discharge. A patient sent home late on a Friday in Brisbane or Adelaide may struggle to contact a GP or obtain a medicine before the weekend. Rural and remote patients may face long distances to a pharmacy. If a medicine is unavailable through the local market, the team may need to arrange supply, identify an equivalent option and document the plan rather than assuming the patient will solve the problem.

Privacy and information governance matter throughout. Sharing a discharge summary with a treating practitioner must comply with applicable Australian privacy requirements, including the Privacy Act 1988 and relevant state or territory rules. My Health Record processes should be used carefully, with attention to consent, access controls and the possibility that a patient’s record does not reflect the latest clinical decision.

Designing For Australian Patients And Services

Australian medication reconciliation should reflect the PBS, Therapeutic Goods Administration requirements and the way medicines are actually obtained. Patients may use a hospital pharmacy, a local community pharmacy, a dose administration aid or medicines supplied by an aged-care service. A discharge list should use generic names while recording brand information when it prevents confusion, especially for devices, combination products or medicines with narrow therapeutic margins.

Everyday habits can undermine otherwise accurate instructions. A person may call a medicine by its brand name, split tablets at breakfast, use a Webster-style pack, or take non-prescription products such as ibuprofen, vitamins or complementary medicines without considering them “medicines”. These products belong in the history because they can affect bleeding, renal function, blood pressure and sedation.

The Australian Commission on Safety and Quality in Health Care’s medication safety expectations provide a useful framework for standardising the work. Hospitals can audit whether medication histories were completed, discrepancies were resolved, discharge summaries were sent within the required local timeframe, and high-risk medicines received documented follow-up. A small sample review can identify whether the problem is a form design issue, a staffing issue, a training gap or poor communication between services.

Measurement should include patient outcomes rather than paperwork alone. Useful indicators include medication-related readmissions, emergency presentations, unintentional omissions, duplicate therapy, pharmacist interventions and patient recall of key changes. Reviewing cases from metropolitan hospitals such as Royal Melbourne or Westmead alongside regional services can reveal different barriers, including access to pathology, transport and after-hours pharmacy support.

Turning Meeting Lessons Into A Discharge Workflow

A practical workflow can begin 24 hours before planned discharge. The team confirms the medication history, reviews new inpatient medicines, checks allergies and adverse reactions, and identifies prescriptions requiring monitoring. Before the patient leaves, a clinician compares the orders with the reconciled list, explains changes using teach-back and sends the relevant documents to the GP and community pharmacy.

The electronic discharge module should make the safe action the easy action. It can pull through the current medication list, flag medicines without an indication, display recent pathology and require a reason for stopping a long-term treatment. It should still allow clinicians to record uncertainty and assign follow-up, because forcing a false sense of completeness is more dangerous than documenting an unresolved issue.

Training works best when it uses realistic cases: an older person with heart failure and renal impairment, a young adult discharged after surgery with opioid analgesia, or a patient whose diabetes medicines changed during an acute illness. Simulation can test whether staff recognise that a correct prescription can still produce harm if the patient receives contradictory verbal instructions.

The professional transition from hospital to community care also benefits from clear role definition. Career discussions at HM17 career advice reflect a wider truth about hospital medicine: safe systems depend on people having the authority, time and support to perform essential work. Medication reconciliation should therefore appear in job expectations, orientation, clinical governance reviews and quality-improvement plans.

A useful final check is simple: can the patient, carer, GP and pharmacist all describe the same post-discharge regimen? If they cannot, the reconciliation is unfinished. The lasting lesson from the Las Vegas meeting is that accurate medication lists are created through a repeated, shared process—history, comparison, explanation, documentation and follow-up—so that the patient leaves hospital with a treatment plan that remains clear beyond the ward.
