Variability in penile duplex ultrasound international practice patterns, technique, and interpretation: an anonymous survey of ISSM members.

ABSTRACT: Penile duplex ultrasound (PDU), combined with pharmacologic stimulation of erection, is the gold standard for the evaluation of multiple penile conditions. A 30-question electronic survey was distributed to members of the International Society for Sexual Medicine (ISSM). The survey assessed the variability in current PDU practice patterns, technique, and interpretation. Chi-square test was used to determine the association between categorical variables. Approximately 9.5% of all 1996 current ISSM members completed the survey. Almost 80% of members surveyed reported using PDU, with more North American practitioners utilizing PDU than their European counterparts (94% vs 69%, p??5?cm/s. This is the first study to assess the variability in the PDU protocol and practice patterns, and to pinpoint areas of improvement. As in other surveys, recall bias, generalizability, and response rate (9.5%) are inherent limitations to this study. Although most respondents report utilizing a standardized PDU protocol, widespread variation exists among practitioners in terms of both technique and interpretation, limiting accurate diagnosis and appropriate treatment of penile conditions.

Project description:Penile shunting is the standard of care in management of ischemic priapism refractory (IPR) to non-surgical interventions. Due to high rates of impotence, corporal fibrosis, and loss of penile length, recent literature suggests these patients benefit from immediate penile prosthesis (PP) placement. An IRB-exempt anonymous electronic survey of the 2168 members of the International Society for Sexual Medicine (ISSM) was conducted. The survey included demographic information, confidence, and experience-related management of IPR. The aim was to evaluate current practice patterns in management of IPR and to investigate the role of immediate PP implantation in the management of prolonged (>36 h) IPR. The survey response rate was 11.6% (n = 251). Most respondents were urologists (173), from the USA (49.1%), and had completed a fellowship in male sexual medicine, men's health, reconstruction, or andrology (71.1%). The majority (91.3%) see at least one case of prolonged priapism (>36 h) that requires surgical management yearly. When looking at volume in training and after, our respondents had a significantly higher experience with penile prostheses (over 70%, > = 10) as compared with shunts (less than 40%, > = 10). Overall, 70.9% of respondents felt more comfortable with a malleable PP than a shunt. However, penile shunts are still preferred as the first line of surgical management by ~80% of respondents as compared with 12.7% who instead prefer a PP. We also found that under 40% of respondents currently use penile MRI or corporal biopsies in their management of prolonged assessment. This is the first study to assess current clinical practices in management of IPR globally. As in any anonymous self-reported survey-based research, recall and sampling bias are an inherent limitation. Penile shunting for IPR continues to be the preferred treatment despite emerging data. Respondents performed PP surgery routinely and feel more confident placing PP than performing penile shunting procedures.

Project description:BackgroundPoint-of-care (POC) ultrasound (POCUS) has become an essential tool in caring for critically ill patients in several specialties. Mastery in POCUS requires competency in image acquisition, image interpretation, and integration into clinical care. Deliberate practice is an effective method for performance improvement in many areas of medical education; however, it is not well described in the literature for POCUS training.ObjectiveTo analyze differences in the effect of deliberate practice in POCUS image interpretation on performance improvement in groups with varying skill levels.MethodsWe recruited attending physicians and trainees with varying degrees of expertise in POCUS to complete a 50-item educational instrument on the interpretation of right ventricle size and function. The instrument incorporated deliberate practice for the task of correctly identifying right ventricle size and function as either normal or abnormal. Pulmonary critical care trainees obtained and interpreted POCUS images of patients with diagnosed acute pulmonary embolism, which were compared with gold-standard, two-dimensional echocardiographic scans obtained by an expert technician and interpreted by a cardiologist board-certified in echocardiography. We mapped learners' cumulative accuracy on a learning curve to assess their performance. In addition, we compared groups on the basis of prior experience with using POC echocardiography.ResultsSeventy-nine of 81 participants completed the survey and examination and were included in the analysis. Of the participants, 69 (87.3%) were trainees. The overall cumulative accuracy for the group was 72.9%. All groups demonstrated improvement in accuracy with repetitive practice.ConclusionDeliberate practice in POC echocardiograph interpretation is effective for improving performance in a wide range of learners. Further study is needed to define accuracy cutoffs for competency to help guide learning plans and program requirements and for application into a model for global POC echocardiography competence.
