The Royal College of Pathologists of Australasia

Recommendations from The Royal College of Pathologists of Australasia about urinary tract infections, PSA testing, vitamin D deficiency screening, serum tumor marker tests and hyperlipidaemia. RCPA is the leading organisation representing pathologists and senior laboratory scientists in Australasia. Its mission is to train and support pathologists and to improve the use of pathology testing to achieve better healthcare.

Do not perform population based screening for Vitamin D deficiency.

The quality of the evidence for the health benefits of an adequate vitamin D status is highly variable. As the main source of vitamin D is UVB sunlight exposure, vitamin D status as assessed by the measurement of 25 hydroxyvitamin D (25OH-D) is correlated with time spent outdoors, exercise and other aspects of a healthy lifestyle including body weight. Vitamin D insufficiency is associated with low levels of exercise, obesity and/or reduced sun light exposure, such as occur more commonly in the elderly, the overweight, the frail and unwell or institutionalised and where there are occupational, racial or cultural reasons. In individuals at risk of vitamin D deficiency, measurement of 25OH-D is an appropriate, case-finding strategy. Routine screening of healthy infants, children and adults (including pregnant women) for vitamin D deficiency is currently not recommended.

How this list was made How this list was made

A list of ten items was compiled after reviewing international literature associated with the Choosing Wisely campaign in Northern America. The College’s advisory committees were canvassed for further relevant evidence based literature and their expert opinions were sought.

The ten items were then adopted as a College Position Statement titled ‘Inappropriate Pathology Requesting’. This list was then sent to RCPA Fellows and Trainees based in Australia to rank the top five tests to include in the Australian Choosing Wisely initiative. The five items selected were approved by both the RCPA's Board of Professional Practice and Quality and the RCPA Board of Directors.
