Around 75% of Australians have experienced a bad reaction to a medication but only 36% of those reported it to a doctor or the Therapeutic Goods Administration (TGA), reveals a new .

polled 544 adults taking one or more medicines to see if those that had an adverse drug reaction (ADR) reported it via phone, email, in person or through the TGA website.

Most of those surveyed were unaware they could use digital tools to report the ADR, helping regulatory authorities to more closely assess specific medications to detect any negative patterns.

Now, a $1.7 million federal government NHMRC grant is helping UniSA researchers to develop new, consumer-focused digital tools to make it easier to report ADRs and cut health costs.

In Australia, up to 3% of all hospital admissions are due to medication-related harm, resulting in an estimated 250,000 admissions and costing the healthcare system $1.4 billion every year.

Lead researcher UniSA PhD candidate Mohammed Dedefo said international studies have shown that digital tools can double the incidence of ADR reporting, but lack of awareness about this option in Australia is contributing to under-reporting.

鈥淪trengthening the vigilance around medication-related harm is essential to monitor the safety of medicines in hospitals and other settings,鈥� he said.

鈥淭he main reason why most people don鈥檛 report adverse drug reactions is because they do not think it is serious enough. However, many don鈥檛 know how to report them either.鈥�

Integrating digital reporting options into widely used healthcare apps and patient portals would increase the reporting rates, researchers said.

Co-author Associate Professor Lisa Kalisch Ellett said leveraging social media and other online platforms would also help reach a broader audience and raise awareness about the need to report ADRs.

鈥淭his data would help the TGA to conduct more thorough assessments and issue warnings to health professionals and consumers if warranted,鈥� Ellett said.

鈥淢edication information could be updated, or the medication withdrawn in the most serious cases.鈥�

The current reporting system, developed by the TGA, is not well-known to most consumers, the researchers said, and is mainly used by pharmaceutical companies.

The findings have been published in the European Journal of Clinical Pharmacology.
