Australasian Society for Infectious Diseases
The Australasian Society for Infectious Diseases (ASID) Inc. is an independent organisation, founded in Melbourne in 1976 by an eminent group of physicians, pathologists and scientists.
Membership encompasses infectious diseases physicians, clinical microbiologists, scientists, infection control practitioners, public health physicians, sexual health physicians, veterinarians and others eminent in the field of infectious diseases.
Top-5 recommendations on low-value practices
1. Do not use antibiotics in asymptomatic bacteriuria.
Rationale and evidence
Rationale
Antibiotic treatment of patients with asymptomatic bacteriuria is generally not indicated as it does not decrease the incidence of symptomatic urinary tract infection. This also includes patients with indwelling urinary catheters. Exceptions to this are pregnant women and those undergoing an urological procedure.

2. Do not take a swab or use antibiotics for the management of a leg ulcer with no indication of clinical infection.
Rationale and evidence
Rationale
Lower leg ulcers, most commonly venous ulcers, are often treated with oral antibiotics even in the absence of evidence of clinical infection. There is no evidence to support this use, except if screening for carriage of multi-resistant organisms.
Also a swab for microscopy and culture in the absence of signs of infection is not recommended. Unnecessary antibiotics and swabbing will lead to increased risk of antimicrobial resistance and patient allergy, and add to healthcare costs.

3. Avoid prescribing antibiotics for upper respiratory tract infections (with the exception of sore throat in populations at high risk for complication of group A strep infection, such as acute rheumatic fever or post-streptococcal glomerulonephritis).
Rationale and evidence
Rationale
Most uncomplicated upper respiratory tract infections are viral in aetiology and antibiotic therapy is not indicated. Oral antibiotic therapy of presumed URTI in febrile young infants is not only 'low value' but can be actively dangerous in delaying presentation to hospital which may inappropriately reassure parents and confound investigations of sepsis. This is a major issue for paediatric primary care and ED presentations. Patient education is an important component of management together with symptomatic treatment. However, infections with streptococcus pyogenes and bordetella pertussis do require antibiotic therapy.
Group A Streptococcal pharyngitis can be followed by 'nonsuppurative' complications such as acute rheumatic fever or post Streptococcal glomerulonephritis. These conditions are very rare in most populations but are more likely to occur in Aboriginal and Torres Strait Islander Australians, Maori and Pacific Islander people aged from 2 to 25 years, or those with known rheumatic heart disease.

4. Do not investigate or treat for faecal pathogens in the absence of diarrhoea or other gastrointestinal symptoms.
Rationale and evidence
Rationale
Testing of faeces for microscopy and culture or by PCR methods should not be performed in the absence of diarrhoea or other gastrointestinal symptoms. Similarly antimicrobial treatment for a gastrointestinal pathogen is not indicated in the absence of symptoms.
For immunocompetent non-traveller children with acute gastroenteritis, there are very few circumstances when a stool test for infection would alter clinical management. Possible exceptions include refugee screening and some neurological syndromes such as enteroviral testing for acute flaccid paralysis.

5. In a patient with fatigue, avoid performing multiple serological investigations without a clinical indication or relevant epidemiology.
Rationale and evidence
Rationale
Multiple serological testing as investigation for a patient with fatigue is not recommended. If such testing is not clinically indicated, there is a risk of false positive results leading to further unnecessary investigations and useless treatments.

How this list was developed
In 2015, an initial list of 10 low value interventions was compiled by the Lead Fellow of the Australasian Society for Infectious Diseases (ASID) Inc following an online discussion in ASID’s discussion forum, Ozbug. The RACP then facilitated a consultation across all ASID members via a survey distributed through the society’s e-newsletter. In the survey, members were asked to rank the 10 suggested interventions and recommend additional items for consideration.
A subsequent shortlist of items was created by selecting the top 7 interventions as ranked by the members from the initial list. The shortlist was sent to ASID’s special interest groups and selected members who had agreed to assist were asked to recommend the items that should comprise the top 5. This final list was endorsed by the ASID Council on 31 July 2015. The top 5 was circulated again to the ASID members for final comments before being approved by ASID’s Executive Committee.
In 2019 following a review by the Executive Committee in response to a comment by Choosing Wisely New Zealand, recommendation 3 was amended. The amended recommendation was then duly consulted with all internal and external stakeholders with an interest and expertise in the subject matter of the amended recommendation.
