Medication Safety in Healthcare: How to Reduce Risks and Prevent Errors

Every day, healthcare professionals across Australia and around the world make thousands of medication-related decisions. Most go smoothly. But when they don't, the consequences can be serious — even life-threatening.

Medication errors are among the most common preventable causes of patient harm in healthcare settings. The Australian Commission on Safety and Quality in Health Care (ACSQHC) has long identified medication safety as a national priority, and for good reason. From hospitals in Sydney to community pharmacies in rural Queensland, the challenge is universal: how do we make sure the right patient gets the right drug, at the right dose, by the right route, at the right time?

This article explores where things go wrong, what the research and practice tell us, and — most importantly — what can be done about it.

Why Medication Errors Happen

Understanding the root causes is the first step toward prevention. Errors rarely happen because someone is careless. More often, they occur when systems fail to support safe practice.

Common Contributing Factors

• Similar drug names or packaging — Drugs like metformin and metronidazole, or insulin glargine and insulin detemir, can be confused at the point of prescribing, dispensing, or administration.

• Poor communication at handover — When patients move between wards, hospitals, or care settings, medication information can be lost or misinterpreted.

• High workload and fatigue — Studies in Australian hospital settings consistently flag understaffing and shift fatigue as contributing factors to clinical errors.

• Illegible or incomplete prescriptions — While electronic prescribing has reduced this significantly, verbal and handwritten orders still occur in some settings.

• Patient factors — Limited health literacy, polypharmacy (taking multiple medications), and poor medication adherence all increase risk on the patient's end.

A nurse working a double shift in a busy emergency department, interrupted mid-task while drawing up an IV medication, is in a situation where errors can slip through — not from negligence, but from system design.

The Australian Context

Australia's healthcare system has made meaningful strides in medication safety over the past decade. The National Medication Safety Program, overseen by the ACSQHC, guides hospitals and health services through a set of national safety standards — including Standard 4, which specifically addresses medication safety.

Electronic Medication Management (eMM) systems have been rolled out progressively across public hospitals in New South Wales, Victoria, Queensland, and other states. These systems flag drug interactions, allergy conflicts, and dose range violations automatically — acting as a critical safety net.

Australia also operates the Therapeutic Goods Administration (TGA), which monitors adverse drug reactions nationally and issues alerts when patterns emerge. Clinicians and consumers alike can report suspected adverse events through the TGA's reporting portal.

Globally, the World Health Organization (WHO) launched its third Global Patient Safety Challenge — "Medication Without Harm" — with a goal of reducing severe, avoidable medication-related harm worldwide. Australia is one of the participating member nations.

High-Risk Medications: Where Extra Vigilance Is Critical

Not all medications carry equal risk. Certain drug classes are responsible for a disproportionate share of serious harm when errors occur. The ACSQHC and clinical bodies like SHPA (Society of Hospital Pharmacists of Australia) highlight the following as high-alert medications:

These medications require double-checking protocols, independent verification, and in many cases, restricted access within healthcare facilities.

Practical Strategies to Prevent Medication Errors

Prevention is not a single intervention — it's a layered system of checks and practices. Here's what works at both the system and individual level.

For Healthcare Organisations

1. Implement and optimise electronic prescribing Digital systems with built-in clinical decision support reduce transcription errors and flag dangerous interactions before they reach the patient. Organisations should ensure these systems are kept up to date with current formulary data.

2. Standardise medication storage and labelling Look-alike and sound-alike drugs should never be stored adjacent to one another. Clear labelling using TALL MAN lettering (e.g., metFORMIN vs metroNIDAZOLE) is now an industry standard promoted by both Australian and international bodies.

3. Mandate structured medication reconciliation at transitions of care The greatest vulnerability is at the point of transition — admission, transfer, and discharge. A structured reconciliation process, ideally led by a pharmacist, dramatically reduces the chance of omission or duplication.

4. Create a reporting culture, not a blame culture When staff fear punishment for near-misses, they stay silent. Organisations that treat error reporting as a learning opportunity — not a disciplinary one — collect the data they need to prevent future harm.

For Clinicians and Pharmacists

• Always verify allergies before prescribing or dispensing

• Use weight-based dosing for children and elderly patients — never assume an adult dose is appropriate

• Counsel patients on their medications at every dispensing event, not just the first time

• Use teach-back techniques to confirm patient understanding

• Flag polypharmacy concerns proactively, especially in aged care settings

For Patients and Carers

Patients are the last line of defence — and an empowered patient catches errors that systems miss.

• Keep an up-to-date, written medication list at all times

• Tell every healthcare provider (including dentists and allied health) about all medications, including over-the-counter drugs and supplements

• Ask questions: "What is this medication for?" and "What should I watch out for?"

• Use a single pharmacy where possible so your pharmacist has a full medication history

• In Australia, the MedicineWise app (by NPS MedicineWise) is a free, evidence-based resource to help consumers manage their medications safely

The Role of Technology in Medication Safety

Beyond electronic prescribing, a range of technologies is actively reshaping medication safety.

Barcode medication administration (BCMA) systems require nurses to scan both the patient's wristband and the medication before administration — creating a digital checkpoint at the bedside. Hospitals in South Australia and Victoria have piloted these systems with promising results.

Automated dispensing cabinets (ADCs) in hospital wards control access to medications and create an audit trail, reducing both errors and diversion of controlled substances.

Artificial intelligence tools are also emerging — some capable of identifying patients at high risk of adverse drug reactions based on their clinical profile before an error ever occurs.

Aged Care: A Particularly Vulnerable Setting

Australia's aged care sector deserves special mention. Residents of residential aged care facilities often take 10 or more medications simultaneously — a situation that dramatically increases the risk of adverse drug reactions, interactions, and errors.

The Royal Commission into Aged Care Quality and Safety (2021) made medication safety a recurring theme in its findings, calling for better oversight, more consistent pharmacist involvement in medication reviews, and tighter governance around psychotropic medication prescribing.

The Australian Government's Quality Use of Medicines (QUM) framework provides guidance for this sector, and regular medication reviews by accredited pharmacists are both recommended and, in many cases, funded through Medicare.

Building a Culture of Safety

Rules, technology, and checklists all matter — but they only work within an organisational culture that genuinely values safety. Research from healthcare quality bodies consistently shows that facilities with strong safety cultures have lower rates of medication errors, better near-miss reporting, and faster learning loops.

Leadership matters here. When senior clinicians openly discuss errors and near-misses in clinical meetings — without shame or blame — they signal to the whole team that safety is a shared responsibility.

Medication safety is not a problem to be solved once. It is an ongoing commitment, one that requires continuous improvement, honest reflection, and collaboration between prescribers, pharmacists, nurses, patients, and the systems that support them all.
