Multi-Virus Rapid Tests Cut Unneeded Antibiotics and Hospital Visits

New research shows that using multi-viral rapid antigen tests at doctor clinics can cut down on unneeded antibiotics and avoid some hospital referrals.

Study Details

Otago University professor and co-author Maria Stubbe said researchers tested the single-swab kits at five doctor practices, which included an after-hours clinic in Wellington, before the tests became available at pharmacies. The team carried out about 1700 swabs during this small-scale study. Doctors and nurses reported that having quick test results meant they were less likely to order extra tests or procedures like x-rays and blood tests.

Benefits and Costs

Stubbe noted that the tests lowered antibiotic prescriptions because antibiotics do not work on viruses, helping fight rising antibiotic resistance. Patients also liked knowing their illness so they could avoid spreading it to others. Influenza regularly kills between 400 and 600 people a year in New Zealand, making it a serious illness that people often underestimate. While the tests are now sold in pharmacies for about $10 each, costs can add up quickly for entire households, and doctors are not funded to provide them for free.

Context

Rapid diagnostic tools are increasingly used in primary care to give immediate answers during patient visits. Public health experts often look for ways to reduce unnecessary medication use, particularly as bacteria become more resistant to standard drugs. Winter illness surges also place a heavy burden on emergency departments, making early detection a key focus for health systems.
