Assessing the safety of minimally invasive partial nephrectomy in octogenarians.

As life expectancy continues to rise, there is a growing cohort of octogenarians that can have oncologic benefit from a partial nephrectomy. This study aims to analyze a large national dataset to compare the safety and outcomes in octogenarians receiving a nephrectomy. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was utilized. All subjects 80-89 years old who received a minimally invasive partial nephrectomy (CPT: 50543) or radical nephrectomy (CPT: 50545, 50546) from 2016 to 2020 were included. Baseline characteristics, comorbidities, and postoperative complications were compared. Chi-square analysis and student t-tests were used to analyze categorical and continuous variables, respectively. 1765 procedures were performed on octogenarians, of which 1299 (73.6%) received a radical nephrectomy and 466 (26.4%) received a partial nephrectomy. When comparing preoperative comorbidities, octogenarians undergoing partial nephrectomy had lower rates of dyspnea at exertion (7.3 vs. 10.6%, p = 0.04), COPD (2.8 vs. 5.9%, p = 0.01), and chronic steroid use (1.5 vs. 3.3%, p = 0.04). No statistically significant differences were seen in any minor (Clavien 1/2) or major post-operative complications (Clavien 3/4). Readmissions were higher in those who received a partial nephrectomy (10.5 vs. 6.5%, p = 0.01); however, there were no significant differences in reoperation (2.4 vs. 1.7%, p = 0.36) or mortality (1.3 vs. 1.8%, p = 0.48). Partial nephrectomy is a safe and feasible operation in octogenarians. Preoperative counseling and appropriate patient selection remain imperative.

National Utilization, Reimbursement, and Urban Versus Rural Trends of Extracorporeal Shockwave Lithotripsy and Ureteroscopic Laser Lithotripsy.

OBJECTIVE: To describe temporal utilization and reimbursement trends of extracorporeal shockwave lithotripsy (ESWL) and ureteroscopy (URS) with laser lithotripsy. METHODS: The Medicare Provider Utilization and Payment Database was queried for all ESWL and URS performed between 2013 and 2020 using Current Procedural Terminology codes: ESWL - 50590; URS - 52352, 52353, 52356. Cases that lacked rural or urban identification codes were excluded. A total of 347,174 ESWL and 401,899 URS cases were identified. Linear regression was performed with statistical significance set to 95% confidence intervals. RESULTS: There was a significant upward trend for URS utilization over the study period (R2 = 0.91, P <.001), but there was not a significant trend for ESWL utilization. In 2013, ESWL was used more frequently than URS, but by 2016, URS was used more frequently than ESWL. From 2013 to 2019, URS utilization increased by 241% and 168% by urban and rural urologists, respectively. URS was also associated with a slight increase in physician reimbursement over time (R2 = 0.87, P <.001), whereas there was no association between ESWL and physician reimbursement. For URS, rural and urban urologists were reimbursed an average of $312.07 (standard deviation [SD] $14.03) and $404.86 (SD $21.96), respectively. For ESWL, rural and urban urologists were reimbursed an average of $456.22 (SD $5.74) and $562.66 (SD $16.68), respectively. CONCLUSION: According to the Medicare database, URS has surpassed ESWL in utilization, especially by urban urologists. Physician reimbursement for ESWL remained higher than URS reimbursement, though URS reimbursement increased slightly in recent years.

Availability of Lactation Accommodation Information for Urology Residency Programs.

OBJECTIVE: To assess whether urology residency programs publish information about lactation accommodations online. Although residencies are required to provide lactation accommodations, there is limited data on whether programs disclose this information. MATERIALS AND METHODS: Webpages of U.S. urology residency programs were assessed for presence of information about lactation accommodations. Program characteristics were noted, as were mentions of resident wellness and diversity. Associations between program characteristics and published lactation accommodations were determined by univariate analysis and development of a multivariate logistic regression model. RESULTS: Of 145 urology residency programs, 72.4% included information about lactation accommodations anywhere on the institution's website There was great variability in ease of accessing information and of quality of information available. Information was most commonly on graduate medical education websites (28.3%) followed by human resources (24.1%), press releases (7.6%), or other sections (11.0%), and least likely to be found on urology residency websites (1.4%). Programs with lactation accommodations anywhere on the institution website were more likely to be larger (P < 0.001), university-based (P < 0.01), and to publish information about resident wellness (P < 0.001), or diversity and inclusion (P < 0.01). On multivariate analysis, only university-based setting and presence of wellness information were predictors of availability of lactation accommodation information. CONCLUSION: Lactation accommodation information is usually not available on urology residency websites and most online information is found elsewhere. Predictors of publishing lactation accommodation information were university-based setting and information about resident wellness. Efforts to recruit and retain female urologists should include making this information more easily accessible.

Transition readiness in pediatric patients with inflammatory bowel disease: patient survey of self-management skills.

OBJECTIVE: Transition may be associated with poor health outcomes, but limited data exist regarding inflammatory bowel disease (IBD). Acquisition of self-management skills is believed to be important to this process. IBD-specific checklists of such skills have been developed to aid in transition, but none has been well studied or validated. This study aimed to describe self-assessment ability to perform tasks on one of these checklists and to explore the relation between patient age and disease duration. METHODS: Patients ages 10 to 21 years with IBD were recruited. An iPad survey queried the patients for self-assessment of ability to perform specific self-management tasks. Task categories included basic knowledge of IBD, doctor visits, medications and other treatments, and disease management. Associations with age and disease duration were tested with Spearman rank correlation. RESULTS: A total of 67 patients (31 boys) with Crohn disease (n = 40), ulcerative colitis (n = 25), and indeterminate colitis (n = 2) participated in the study. Mean patient age was 15.8 ±â€Š2.5 years, with median disease duration of 5 years (2 months-14 years). The proportion of patients who self-reported ability to complete a task without help increased with age for most tasks, including "telling others my diagnosis" (ρ = 0.43, P = 0.003), "telling medical staff I do not like or am having trouble following a treatment" (ρ = 0.37, P = 0.003), and "naming my medications" (ρ = 0.28, P = 0.02). No task significantly improved with disease duration. CONCLUSIONS: Self-assessment of ability to perform some key tasks of transition appears to improve with age, but not with disease duration. More important, communication with the medical team did not improve with age, despite being of critical importance to functioning within an adult care model.

MRI diffusion-weighted imaging (DWI) in pediatric small bowel Crohn disease: correlation with MRI findings of active bowel wall inflammation.

BACKGROUND: Restricted diffusion on diffusion-weighted imaging (DWI) sequences during magnetic resonance enterography (MRE) has been shown in segments of bowel affected by Crohn disease. However, the exact meaning of this finding, particularly within the pediatric Crohn disease population, is poorly understood. OBJECTIVE: The purpose of this study was to determine the significance of bowel wall restricted diffusion in children with small bowel Crohn disease by correlating apparent diffusion coefficient (ADC) values with other MRI markers of disease activity. MATERIALS AND METHODS: A retrospective review of pediatric patients (≤ 18 years of age) with Crohn disease terminal ileitis who underwent MRE with DWI at our institution between May 1, 2009 and May 31, 2011 was undertaken. All of the children had either biopsy-proven Crohn disease terminal ileitis or clinically diagnosed Crohn disease, including terminal ileal involvement by imaging. The mean minimum ADC value within the wall of the terminal ileum was determined for each examination. ADC values were tested for correlation/association with other MRI findings to determine whether a relationship exists between bowel wall restricted diffusion and disease activity. RESULTS: Forty-six MRE examinations with DWI in children with terminal ileitis were identified (23 girls and 23 boys; mean age, 14.3 years). There was significant negative correlation or association between bowel wall minimum ADC value and established MRI markers of disease activity, including degree of bowel wall thickening (R = (-)0.43; P = 0.003), striated pattern of arterial enhancement (P = 0.01), degree of arterial enhancement (P = 0.01), degree of delayed enhancement (P = 0.045), amount of mesenteric inflammatory changes (P < 0.0001) and presence of a stricture (P = 0.02). ADC values were not significantly associated with bowel wall T2-weighted signal intensity, length of disease involvement or mesenteric fibrofatty proliferation. CONCLUSION: Increasing bowel wall restricted diffusion (lower ADC values) is associated with multiple MRI findings that are traditionally associated with active inflammation in pediatric small bowel Crohn disease.

Variation in infliximab administration practices in the treatment of pediatric inflammatory bowel disease.

OBJECTIVES: Infliximab is used increasingly to treat inflammatory bowel disease (IBD). Infliximab is supplied in 100-mg vials. Doses that are typically calculated as 5 mg · kg⁻¹ · dose⁻¹ are commonly rounded up or down to the nearest 100 mg. Variation in dosing practices is unknown. Underdosing based on weight may increase the risk for disease exacerbation, whereas overimmune suppression could increase the risk of infection. Children may be at greater risk from dosage rounding. We aimed to characterize infliximab dosing practices, the use of corticosteroid premedication, and duration of infusions among pediatric practitioners participating in the ImproveCareNow Network, a national collaboration to improve IBD care and outcomes. METHODS: A national survey of infliximab dosing practices was sent to 279 pediatric IBD practitioners from March to December 2011. Double data reconciliation, t test, and χ² analyses were performed. RESULTS: The response rate was 74% (N = 207). Thirty-eight percent (78/207) indicated that their practice has no uniform approach to the rounding of doses. Of 114 respondents indicating a uniform approach to rounding doses, 43% always round up to the nearest 100 mg, 33% always round up or down to the nearest 100 mg, and 14% never round doses. In addition, 28% of respondents always premedicate with corticosteroids and 12% never premedicate. Of respondents indicating "it depends," 95% premedicate if there has been a previous infusion reaction, 46% if there has been a prolonged lapse between treatment doses, 40% if antibodies to infliximab are present, and 11% if giving infliximab monotherapy. The duration of infusions is most often 2 hours, but varies between 1 and 4 hours. CONCLUSIONS: Wide variation exists in the practice of infliximab administration in pediatric IBD. The effect of these variations on outcomes is unknown.
