Regulatory authorities have long accepted a microbial threshold of 105 CFU/mL as the standard for diagnosing UTI based on standard urine cultures. However, microbial thresholds considered clinically relevant remain in dispute. The aim of this systematic scoping review is to assess the evidence supporting a threshold of 105 CFU/mL, to review microbial threshold guidelines, and highlight knowledge gaps in the diagnosis of UTI. A total of 36 guidelines containing 144 recommendations were identified with 64% of guidelines (n = 23) and 58% of recommendations (n = 83) published in the last six years (2016– 2023). Recommendations have changed over time and across variables including the geographical location of the guideline, urine specimen collection method, patient sex, and category of UTI. Guidelines uniformly agreed with suprapubic needle specimen collection; however, there was no consensus for midstream collected urine samples. Guideline microbial thresholds for clinical UTI diagnosis were higher for women at average risk (105 CFU/mL) than for men (102 to 105 CFU/mL) and high-risk patients (102 to 104 CFU/mL). Guidelines relied heavily on 48 research articles from 20 author teams published between 1956 and 2019 and recommendations frequently cited 23 research articles by 15 author teams published between 1956 and 2013. Evidence supporting 105 CFU/mL threshold originated in the mid-1950s from 4 research articles, whereas 18 frequently cited peer-reviewed publications focused their research on the clinical relevance of lower thresholds (101 to < 105 CFU/mL). This review demonstrates a lack of consensus for urine culture microbial threshold recommendations for the clinical diagnosis of UTI. Guidelines are primarily based upon sparse and dated evidence. Additional research is needed to inform clinically meaningful diagnostic microbial thresholds in the diagnosis of UTI.Keywords: urinary tract infection, guideline, microbial, diagnostic threshold, uropathogen, scoping systematic review

A rigorous learning needs assessment (LNA) is a crucial initial step in the Continuing Professional Development (CPD) process. This scoping review aimed to collate, summarize, and categorize the reported LNA approaches adopted to inform healthcare professional CPD and highlight the gaps for further research. In August 2020, nine bibliographic databases were searched for studies conducted with any health professional grouping, reporting the utilized LNA to inform CPD activities. Two reviewers independently screened the articles for eligibility and charted the data. A descriptive analytical approach was employed to collate, summarize, and categorize the literature. 151 studies were included in the review; the majority adopted quantitative methods in the form of self-assessment surveys. Mixed-methods approaches were reported in only 35 studies. Descriptions of LNA development lacked detail of measures taken to enhance their rigor or robustness. These findings do not reflect recommendations offered by the CPD literature. Further investigations are required to evaluate more recently advocated LNA approaches and add to their limited evidence-base. Similarly, the existing support afforded to CPD developers warrants further study in order to identify the necessary resource, infrastructure and expertise essential to design and deliver effective CPD programs.
