BACKGROUND

Mastery learning assumes that given enough time and appropriate instructional strategies, most trainees will be able to achieve proficiency. Expert-level performance requires numerous hours of intensive and focus practice. We aimed to study whether it was possible for surgical trainees to achieve expert-derived proficiency level in laparoscopic suturing using the Advanced Training in Laparoscopic Suturing (ATLAS) curriculum over a short period of time.

STUDY DESIGN

A multicenter IRB approved prospective study included surgery residents and minimally invasive fellows. Participants underwent weekly supervised instruction and assessments of ATLAS skills and self-directed practice between sessions over 12 weeks. Participants were asked to practice until they achieved previously established proficiency benchmarks of expert laparoscopic surgeons.

RESULTS

Fifteen participants, PGY2 to PGY6, from 3 institutions practiced on the ATLAS curriculum. Three participants were able to achieve proficiency on the entire curriculum, with a cumulative practice time varying between 3.4 and 7.6 hours. Individual tasks had varying degrees of difficulty ranging from 85% proficiency on task 1 to 33.3% proficiency for task 6. Using a mixed-method model, the mean cumulative hours of practice to reach the benchmark threshold was estimated for each task and varied from 4.5 to 13.2 hours. The improved performance was associated with higher PGY level and proficiency in FLS.

CONCLUSIONS

This study demonstrates that it is possible for some senior surgical trainees to achieve proficiency in an expert-level laparoscopic suturing curriculum. This study establishes a learning curve for each ATLAS individual task. Some learners may not be able to achieve proficiency on the entire curriculum over a short period of practice. Additional studies are needed to assess how to shorten the learning curve with effective instructional methods such as expert-guided training with immediate feedback.

OBJECTIVES

Although cross-sectional studies have shown that ankylosing spondylitis-specific factors correlate with depressive symptom severity, the association of these factors over time is unresolved. We examined the demographic and clinical factors associated with longitudinal depressive symptom severity in AS patients.

METHODS

We analyzed sociodemographic, clinical, behavioral and medication data from 991 patients from the Prospective Study of Outcomes in Ankylosing spondylitis cohort, and measured depression severity with the Center for Epidemiological Studies Depression (CES-D) Scale administered at approximately 6-month visit intervals. Multivariable longitudinal negative binomial regression models were conducted using generalized estimating equation modeling to assess the demographic, clinical, and medication-related factors associated with depression severity by CES-D scores over time.

RESULTS

The median baseline CES-D score (possible range 0-60) was 10.0 (interquartile range = 5, 17). In longitudinal multivariable analyses, higher CES-D scores were associated with longitudinal smoking, greater functional impairment, greater disease activity, self-reported depression, and poor global health scores. Marital status (e.g., being married) was associated with lower CES-D. Adjusted mean CES-D scores in our model decreased over time, with a significant interaction between time and gender observed.

CONCLUSION

This study identified longitudinal clinical factors such as greater disease activity, greater functional impairment, and poor global health to be associated with longitudinal depression severity. These factors are potentially modifiable and may help manage depressive symptoms in AS.

Child obesity is understudied in Asian Americans, which include a growing population of recent immigrants. We examined the relationship between maternal nativity and time in the US, and obesity and obesogenic behaviors among Asian American children. We analyzed public-use data from the 2013-2016 California Health Interview Survey for Asian American children ages 2 to 11 years. We used logistic regression to determine the odds of obesity and obesogenic behaviors associated with maternal nativity and time in the US. This study included n = 609 children. Children of US-born mothers had lower odds of obesity (adjusted odds ratio, AOR, 0.12; 95% CI 0.02 to 0.91) and lower fruit intake (AOR 0.15, 95% CI 0.03 to 0.81) than children of recent immigrants ( 5 years in the US). Asian American children with recent immigrant mothers are more likely to be obese and eat less fruit than children with US-born mothers. Efforts to prevent obesity and increase fruit consumption are particularly important for this vulnerable population of children of recent immigrants.

BACKGROUND

Bicycle riding's impact on erectile function remains a topic of great interest given cycling's popularity as a mode of transportation and exercise.

AIM

We evaluated risk factors for sexual dysfunction in male cyclists with the primary intention of determining if genital/pelvic pain and numbness are associated with erectile dysfunction (ED).

METHODS

We surveyed male cyclists using an online anonymous questionnaire. Cyclists were queried on their demographics, cycling experience, and sexual function using the Sexual Health Inventory for Men (SHIM). ED was diagnosed when a completed SHIM score was 22. Regression analysis was used to evaluate the risk of ED in men with genital/pelvic pain or numbness after riding. The survey was designed in the United States.

OUTCOMES

Quantitative characterization of cycling habits, onset and timing of genital pain and numbness, and SHIM score.

RESULTS

A total of 1635 participants completed the survey. A majority of men were over the age of 50 (58%, 934/1,607), Caucasian (88%, 1,437/1,635), had been active cyclists for over 10 years (63%, 1,025/1,635) and used road bikes (97%, 1,578/1,635). Overall, 22%, 30%, and 57% of men reported ED, genital pain, and genital numbness, respectively. While controlling for cohort demographics, body mass index, cycling intensity and equipment, and medical comorbidities, no saddle characteristics were associated with the risk of developing genital numbness. However, men reporting penile numbness were at higher risk of reporting ED (odds ratio [OR] = 1.453, P = .048). In addition, quicker onset of numbness and resolution of numbness within a day was associated with impaired erectile function. For example, numbness occurring less than 1 hour after cycling had greater odds of leading to ED than numbness after 5 hours (OR = 2.002, P = .032). Similarly, genital pain occurring less than 1 hour (OR = 2.466, P = .031) after cycling was associated with higher ED risk.

STRENGTHS & LIMITATIONS

Strengths include a large sample size of high-intensity cyclists and validated questionnaire use. Limitations include reliance on anonymous self-reported survey data and minimal inquiry into the riding preferences and terrain traversed by cyclists.

CONCLUSIONS

Pelvic pain and numbness are common complaints among male riders in the United States. Men with such complaints are more likely to also report ED especially if it occurs earlier in the ride. Although direction of causality and temporality are uncertain, alleviation of factors resulting in pelvic discomfort may reduce cycling's impact on sexual function. Such interventions are critical given that cycling for both active travel and aerobic exercise confers numerous health benefits. Balasubramanian A, Yu J, Breyer BN, et al.

Surgical-site delivery of local anesthetics decreases pain and opioid consumption after total knee arthroplasty (TKA). The optimal route of administration is unknown. We compared local anesthetic delivery using periarticular soft-tissue infiltration to delivery using a combination of preimplantation immersion and intra-articular injection (combination treatment). The records of patients who underwent unilateral, cemented, primary TKA with spinal anesthesia and adductor canal blocks at a single Veterans Affairs Medical Center were retrospectively reviewed. Three subgroups were compared, including controls who did not receive additional local anesthetics, patients who received periarticular infiltration, and patients who received combination treatment. Mean daily pain scores and mean 24-hour opioid consumption on postoperative days (PODs) 0 and 1 were calculated, and analysis of variance was used to assess for significant differences. Factors that were associated with lower pain scores and opioid consumption were then identified using multivariate stepwise regression. There were 26 controls, 25 periarticular infiltration patients, and 39 combination patients. The periarticular infiltration cohort had significantly lower mean pain scores and opioid consumption than controls on POD 0, but not on POD 1. The combination cohort had significantly lower mean pain scores and opioid consumption than controls on PODs 0 and 1. There were no significant differences between the infiltration and combination groups on either day. Multivariate regression analysis showed that infiltration was associated with significantly decreased opioid consumption on both days and decreased pain on POD 0. Combination treatment was associated with significantly decreased pain and opioid consumption on both days. Both local anesthetic periarticular infiltration and combination treatment are associated with decreased pain and opioid consumption after TKA. The stronger effects of the combination treatment compared with periarticular infiltration on POD 1 suggests that combination delivery may have a longer duration of action.

: The diversity in pulmonary and critical care medicine (PCCM) training programs in the United States has not been systematically evaluated, despite emphasis on workforce diversity and its role in improving gender and racial healthcare disparities. : We analyzed the diversity of the PCCM pipeline by gender, race, and ethnicity over the last 10 years. : The PCCM pipeline was defined as internal medicine residents, fellowship applicants, and fellows in pulmonary-only, critical care medicine-only, and combined PCCM programs. Data on gender, race, and ethnicity were obtained from 2009 to 2018 graduate medical education census data and the Association of American Medical Colleges Electronic Resident Application Service. We used the Association of American Medical Colleges definition of "underrepresented in medicine" (UIM), which comprises African American/black, Hispanic/Latino, American Indian/Alaska Native, or Native Hawaiian/Pacific Islander physicians. : Over the last decade, the percentage of female fellows was unchanged in pulmonary (range, 19.4-37.1%), critical care medicine (range, 17.6-31.9%), and PCCM programs (range, 29.5-35.2%). To capture the current snapshot of data across residents, applicants, and fellows, we analyzed 2018 data and found that there was a drop-off from the percentage of female internal medicine residents (41.9%) to the percentage of female applicants and fellows (⩽33% in all three programs). The percentage of UIM fellows decreased in PCCM programs over the last decade to 10.3%. In 2018, there was a drop-off from the percentage of UIM residents (13.7%) to the percentage of UIM fellows in all three programs (12.9% in all three programs). : Striking disparities remain in gender, race, and ethnicity in the pipeline of trainees in PCCM programs; these have not improved (for gender) or have even worsened (for race and ethnicity) over the last decade.

OBJECTIVE

To describe the use of Lean in urology at Zuckerberg San Francisco General, a community safety-net and trauma hospital that serves as a major teaching site for the University of California San Francisco.

METHODS

We examined our process improvement activities from 2016 to 2018. Our Lean Daily Management System (DMS) includes a 15-minute team huddle ("urology Lean work") of service residents, faculty, clinic and operating room nursing staff, and anesthesia liaisons. Our DMS also includes a 5-minute preoperative huddle. Besides team-building, urology Lean work surfaces logistics, safety or equipment improvement ideas, and ensures progress and completion of initiated projects.

RESULTS

Over a 2-year period we developed and completed 67 projects. Projects impacted the outpatient setting (57%), followed by the operating room (22%), the Urology service (12%), and inpatient setting (9%). We completed projects in the following domains: safety (26%), quality (22%), care experience (21%), workforce care and development (13%), equity (11%), and financial stewardship (7%). Urology Lean work reduced new patient clinic access time (119-21 days) and Bacillus Calmette-Guérin in clinic treatment time (180-105 minutes). The average proportion of urology on-time surgeries was better than the overall surgery on-time surgeries (71% v 61%).

CONCLUSION

Urology Lean work successfully applied DMS in a service specific yet holistic approach. Urology Lean work improved resident engagement in quality and safety endeavors and served as a DMS model throughout perioperative and clinic areas.
