Pressure injuries present significant challenges in clinical care, leading to severe complications such as infection, pain and delayed wound healing. They are a common chronic wound that contribute to increased morbidity, prolonged hospital stays and substantial healthcare costs. Despite national efforts to enhance chronic wound management, development of optimal treatment strategies remains a priority. The Pressure Injury Treatment Advisory (PITA) Quick Guide was developed to provide an evidence-based guide to support clinicians in pressure injury management. A survey was conducted to evaluate clinician perspectives on the usability and practicality of the Guide in acute care, residential aged care and community settings. A post-test survey was conducted on a convenience sample of healthcare professionals from three healthcare settings across metropolitan, regional and rural Australia. The survey included 5-point Likert-scale items assessing ease of use, effectiveness and integration with workflows. Three hundred and two responses were received (66.7% response rate). Clinicians expressed overwhelmingly positive perceptions, with over 95% agreeing or strongly agreeing on the guide's utility and effectiveness. No respondents strongly disagreed with any item. Residential aged care and rural clinicians rated the tool slightly higher than acute care and medical clinicians. The PITA Quick Guide was well-received across all settings, demonstrating strong potential to enhance evidence-based pressure injury management.

Secondary care centre outpatient gynaecology clinic in Calgary, Alberta, Canada.
3951 electronic health records of women aged 18–45 years who presented to a gynaecology clinic in Calgary, Canada, between January 2014 and December 2019 were reviewed. We identified 180 patients with PCOS using the Rotterdam criteria. Participants were excluded if they were biologically male, pregnant at the time of the consultation, did not meet the date criteria or if their consultation note was missing. The chart data were connected to the Practitioner Claims and the Discharge Abstract Database by personal health number.
Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 68 case definitions for PCOS were estimated. Case definition performance was graded.
Of the 68 case definitions tested, none had high validity. The best performing case definitions were: (1) ≥3 instances of International Classification of Diseases-9 code 256.4 (polycystic ovaries) with exclusion codes (sensitivity 23.89%, specificity 99.59%, PPV 74.14%, NPV 96.35%) and (2) 626.X (irregular menstruation), 704.1 (hirsutism) and ≥3 instances of code 256.4 with exclusion codes (sensitivity 2.78%, specificity 99.97%, PPV 83.33%, NPV 95.40%).
We identified several case definitions for PCOS of moderate validity with high PPV (>70%) for case ascertainment in PCOS research in jurisdictions with similar administrative health data. These case definitions are limited by low sensitivity, which should be considered when interpreting research findings.
