This is the justified realm of point-of-care ultrasound (POCUS) where a clinician answers a clinical question at the bedside allowing for fast triage into appropriate care. I am a fan of POCUS: I have seen instances where care was appropriately expedited. I am also a fan of the targeted scan performed by sonographers in situations where patients have had recent examinations and monitoring is all that is needed. But most patients still need a full study.</p><p>Complex protocols are efficacious and safe and the hallmark of sonography practice. Sonographer-led protocol-driven examinations, if performed completely, rule out other pathology, while confirming or excluding a differential diagnosis. In addition, while sometimes the differential is all that matters, its exclusion in an abbreviated scan may mean the true pathology is missed because it was not raised as a possibility by the referrer or recognised as a potential alternative diagnosis by the sonographer. When protocols are discarded, mistakes occur, pathology is missed, and additional (and potentially unnecessary) imaging may be performed. Protocol-driven studies are also a supportive approach for sonographers early in their career trajectory but take time to perform. In this issue of AJUM, Deslandes <i>et al</i><span>¹</span> show that to follow published guidelines for endometriosis diagnosis, a longer appointment time is needed. In essence, a one-slot booking system where every patient gets the same amount of time is not going to work. In the absence of a fee per service model, each sonographer would take as long as needed to get the images they required, but the fee per service model encourages practices to ‘squeeze’ more patients in and therefore does not adequately support full protocol-driven studies. Protocol-driven sonography is ideal. The question, though, is which protocol?</p><p>Many professional societies have guidelines for scanning but appropriately stop short of mandating their use. As health professionals, we should make individual decisions about how, and when, it is appropriate to offer an abbreviated scan. Yet, that takes a level of skill and expertise gained through years of experience, and therefore, the protocols and guidelines we use help to maintain quality care for all practitioners and patients. So who decides on these guidelines? Often, they are determined by international societies and are influenced by experts who typically work in well-resourced healthcare systems. Is it time we had local guidelines? Or are they too costly to develop for smaller countries? Also, in our region, should Australia and New Zealand have different guidelines from the rest of the world?

Hence, this study aims to: (i) determine whether there is a statistical significance in growth rates between solitary GBPs versus multi-polyps; (ii) determine, in a four-year period, the proportion of GBPs in this study’s total cohort that exhibit growth compared to previous studies.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>A retrospective, quantitative, cohort study was implemented utilising 100 consecutive patient records from three private radiology clinics. These were assessed against the eligibility criteria and allocated into the solitary or multi-polyp study group, depending on number of GBPs detected on initial and follow-up ultrasound examinations conducted 6–48 months later. Patient age, GBP sizes, time interval between initial and follow-up ultrasound examinations and GBP growth rates were compared between the study groups utilising Student’s <i>t</i> tests.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>No statistically significant difference was found between the study groups according to gender, age, GBP size and time between ultrasound examinations. Furthermore, there was no statistically significant difference between the growth rates of solitary and multi-polyp groups (P = 0.77). Most GBPs [92/100 (92%)] grew &lt;2 mm in maximal diameter, while 8/100 (8%) of GBPs grew ≥2 mm in maximal diameter at follow-up.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>The large majority of GBPs maintained size stability at follow-up. On average, solitary GBPs did not grow faster than multi-polyps, although further research is recommended to reinforce this.</p>\u0000 </section>\u0000 </div>","PeriodicalId":36517,"journal":{"name":"Australasian Journal of Ultrasound in Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajum.12284","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46564269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
