RESUMO
AIMS: This study aims to assess the impact that delivering an introductory interventional radiology (IR) lecture series has on the knowledge and perception of the specialty among medical students in a resource-limited setting with, until recently, no IR presence. MATERIALS AND METHODS: An introductory four-hour lecture series in IR was delivered to third-year medical students in Tanzania. Prior to and following the lecture series, participants completed a 27-item paper-based survey assessing their knowledge and perception of the specialty. RESULTS: Out of a class of 213, the pre- and post-lecture survey was returned by 148 (69.5%) and 151 (70.9%) respondents, respectively. 94.5% of respondents indicated that they were aware of IR as a specialty. Among respondents, 97.3% expressed interest in having IR lectures integrated into their curriculum, compared to 29.0% that reported having any prior IR training. 27.3% believed their knowledge in IR compared to other specialties was either "good" or "excellent", which improved to 43.3% (p<0.001). Identification that IR physicians consult patients directly, have outpatient clinics, have inpatient beds, and do rounds improved from 55.4% to 81.1% (p<0.001), 49.7% to 60.3% (p=0.066), 48.3% to 66.7% (p=0.001), and 52.0% to 66.2% (p=0.013), respectively. CONCLUSION: By introducing short lectures on IR-relevant topics, knowledge and perception of IR improved among Tanzanian medical students. Early education and exposure to IR should be prioritized to promote the continued growth of the specialty in this setting.

OBJECTIVE: Breast imaging services often experience a significant degree of variability in patient flow, leading to delay in time to diagnostic resolution, commonly referred to as time to resolution (TTR). This study applies Lean Six Sigma Methodology (LSSM) to reduce TTR and enhance patient outcomes. METHODS: This study was IRB-approved. A baseline audit was done using cases of mammographic recalls (BI-RADS 0) to measure baseline TTR. Multidisciplinary meetings with all members of the breast imaging service, alongside a study of patient complaint data, were utilized to identify issues that were causing prolonged TTR. Following that, possible solutions were proposed and implemented. A post-implementation audit was conducted, and the resulting TTRs were compared. Significant differences in TTR between the pre- and post-solution implementation were assessed using the Mann-Whitney U test. RESULTS: During the baseline audit of 8 months, 589 cases of mammographic recalls (BI-RADS 0) were identified, and the resulting average TTR was 86.3 days. During the post-implementation period of 3 months, 370 mammographic recalls (BI-RADS 0) occurred, with a resulting average TTR of 36.0 days. After applying LSSM, TTR was reduced by 58.3% (Pâ <â 0.01). Some changes implemented included training the coordinators, establishing a rapid diagnostic clinic using previously underutilized equipment, and having radiologists assigned full-time to the breast imaging service. CONCLUSION: Our team has successfully managed to identify various causes behind the prolonged TTR using LSSM. Team collaboration was essential to study and decide on a more achievable TTR.
