Antibiotic guidelines are constantly evolving, and staying informed is crucial for effective patient care. The latest updates from Therapeutic Guidelines highlight significant changes in how we approach antibiotic use, impacting areas like perinatal infections, surgical procedures, and wound care. This is a critical issue because the rise of antibiotic resistance demands that we continuously refine our practices.
The not-for-profit healthcare publisher, Therapeutic Guidelines, has released its final antibiotic guidance update for 2025. This December release is the third update of the year, following previous versions in March and September. This shows how dynamic the field of medicine is.
Here's a breakdown of the key areas that have been updated:
- Perinatal infections: Changes in this area are designed to improve outcomes for both mothers and newborns.
- Surgical prophylaxis: These updates refine the use of antibiotics before surgery to prevent infections.
- Skin and soft tissue infections: New guidance helps in the treatment of common skin infections.
- Traumatic wounds: These changes address the best ways to manage infections from injuries.
Summary tables have also been updated, including information on antibiotic prescribing in primary care to reflect changes in guidance for lactational mastitis and bite wounds, including clenched-fist injuries.
Let's dive into some specific changes:
- Intra-amniotic infection: Metronidazole is now included in the first-line treatment to cover a wider range of bacteria.
- Surgical prophylaxis (for adults weighing 120 kg or more): A cefazolin dose of 3 g is now recommended for adults with a glomerular filtration rate above 40 mL/min.
- Aminoglycoside dosing: Updated dosage regimens for gentamicin (adults and children) and the recommendation of tobramycin as an alternative.
- Lactational mastitis: Expanded guidance with clearer diagnostic criteria and intravenous antibiotic regimens.
- Water-immersed traumatic wounds: Trimethoprim+sulfamethoxazole is the recommended oral antibiotic.
These guidelines were initially published over 40 years ago to combat antibiotic resistance. Professor Mark Morgan, Chair of the RACGP Expert Committee – Quality Care, notes that the number of conditions covered has grown from 59 to around 200.
Professor Morgan emphasizes that these updates reflect not only the increase in conditions covered but also the evolving landscape of antimicrobial resistance. The updates to the management of perinatal infections, surgical and endocarditis prophylaxis were ‘major’, and that other ‘significant’ updates include management of lactational mastitis and wound infections associated with water.
But here's where it gets controversial... Professor Morgan also points out that the Antibiotic Expert Group has identified areas where research is lacking. These include the optimal duration of antibiotic use and specific conditions like bronchiectasis exacerbations and infection-associated lung effusions. This highlights the ongoing need for research in this critical area.
Professor Morgan believes that guidelines will inevitably become more complex over time.
He recommends that GPs regularly refer to the Therapeutic Guidelines’ summary table.
And this is the part most people miss... The speed at which new evidence emerges means that all clinical practice guidelines should ideally be ‘living’ guidelines, with mechanisms to enable swift updates of key recommendations.
