Improving the Quality of Upper Urinary Tract Stone Surgery: External Validation of a Statewide Collaborative's Efforts to Reduce Emergency Department Visits After Ureteroscopy.

PURPOSE: The ROCKS (Reducing Operative Complications from Kidney Stones) program in MUSIC (Michigan Urological Surgery Improvement Collaborative) was created to optimize ureteroscopy outcomes. Through data collection, distribution of reports, patient education, and standardization of medication, post-ureteroscopy emergency department visits in Michigan have declined. It is unclear whether this is because of statewide quality efforts or due to national trends. We therefore sought to understand emergency department visit rates in Michigan compared to a national data set. MATERIALS AND METHODS: We compared the MUSIC ROCKS clinical registry in Michigan against a national cohort, Optum's de-identified Clinformatics Data Mart, from 2016-2021 (excluding Michigan). We identified patients who underwent ureteroscopy and the proportion who had a postoperative emergency department visit within 30 days. Emergency department rates were modeled over time, adjusting for age, gender, comorbidity, and ureteral stenting. RESULTS: We identified 24,688 patients in MUSIC ROCKS and 99,340 in the Clinformatics Data Mart database who underwent ureteroscopy. The risk-adjusted emergency department visit rate in MUSIC ROCKS significantly declined over the study period (10.5% in 2016 to 6.9% in 2021, P < 0.001) while the mean emergency department visit rate in the Clinformatics Data Mart cohort was 9.9% and did not change over time (9.6% in 2016 to 10% in 2021). Comparing emergency department visits between the cohorts, the MUSIC ROCKS rate significantly declined relative to the Clinformatics Data Mart (P < 0.001) over the study period. CONCLUSIONS: Postoperative emergency department visit rates in Michigan have declined significantly after ureteroscopy since the establishment of MUSIC ROCKS. This decline outpaced national rates, providing evidence that systematic quality initiatives can improve urological care.

Comparing the Etiology of Viral Acute Respiratory Illnesses Between Children Who Do and Do Not Attend Childcare.

BACKGROUND AND OBJECTIVE: Childcare attendance is a common risk factor for acute respiratory illness (ARI) in young children. Our goal was to better understand the specific respiratory viruses that predominate in childcare, which may support the development of tailored illness prevention and intervention strategies in childcare settings. METHODS: Using data from a prospective household cohort of ARI surveillance, we assessed specimen from 1418 ARIs reported by 359 childcare-aged children over 6 study seasons (2012/2013 through 2017/2018). Respiratory swabs were tested by polymerase chain reaction for 9 respiratory viruses. A mixed-effect logistic regression model was used to compare odds of various viral detection outcomes. The Shannon's Diversity index was used to compare the richness (ie, number of species) and diversity (ie, relative species abundance) associated with respiratory viruses detected in both groups. RESULTS: At least 1 virus was detected in 75.5% of childcare-associated ARIs and in 80.1% of homecare ARIs. Compared with illnesses among homecare children, childcare illnesses were associated with significantly higher odds of detected adenovirus (odds ratio = 1.86, 95% confidence interval = 1.05-3.28) and human metapneumovirus (odds ratio = 1.76, 95% confidence interval = 1.03-3.0). The pool of viruses associated with childcare ARI was found to be significantly richer and more diverse than that of viruses associated with homecare ARI ( P < 0.0001). CONCLUSIONS: Children attending childcare experience a higher risk of adenovirus and human metapneumovirus infection and are regularly exposed to a rich and diverse pool of respiratory viruses in childcare environments. Our results underscore the necessity of thorough and multifaceted viral prevention strategies in childcare settings.

Comprehensive History and Physicals are Common Before Low-Risk Surgery and Associated With Preoperative Test Overuse.

INTRODUCTION: The Centers for Medicare and Medicaid Services (CMS) recently eliminated the requirement for preoperative history and physicals (H&Ps) prior to ambulatory surgery. We sought to assess variations in separately billed preoperative H&P utilization prior to low-risk ambulatory surgery, describe any relationship with preoperative testing, and identify independent predictors of these consultations prior to this policy change to help characterize the potential unnecessary utilization of these consultations and potential unnecessary preoperative testing prior to low-risk surgery. MATERIALS AND METHODS: A retrospective cohort study was performed using claims data from a hospital value collaborative in Michigan from January 2015 to June 2019 and included patients undergoing one of three ambulatory procedures: breast lumpectomy, laparoscopic cholecystectomy, and laparoscopic inguinal hernia repair. Rates of preoperative H&P visits within 30 d of surgical procedure were determined. H&P and preoperative testing associations were explored, and patient-level, practice-level, and hospital-level determinants of utilization were assessed with regression models. Risk and reliability-adjusted caterpillar plots were generated to demonstrate hospital-level variations in utilization. RESULTS: 50,775 patients were included with 50.5% having a preoperative H&P visit, with these visits being more common for patients with increased comorbidities (1.9 ± 2.2 vs 1.4 ± 1.9; P < 0.0001). Preoperative testing was associated with H&P visits (57.2% vs 41.4%; P < 0.0001). After adjusting for patient case-mix and interhospital and intrahospital variations in H&P visits, utilization remained with significant associations in patients with increased comorbidities. CONCLUSIONS: Preoperative H&P visits were common before three low-risk ambulatory surgical procedures across Michigan and were associated with higher rates of low-value preoperative testing, suggesting that preoperative H&P visits may create clinical momentum leading to unnecessary testing. These findings will inform strategies to tailor preoperative care before low-risk surgical procedures and may lead to reduced utilization of low-value preoperative testing.

Prevalence and determinants of oral and cervicogenital HPV infection: Baseline analysis of the Michigan HPV and Oropharyngeal Cancer (MHOC) cohort study.

We determined baseline oral and cervicogenital human papillomavirus (HPV) prevalence and determinants of infection in the Michigan HPV and Oropharyngeal Cancer (MHOC) study. We enrolled 394 college-age and older participants of both sexes in Ann Arbor, Michigan and the surrounding area. All participants provided an oral sample at baseline, and 130 females provided a cervicogenital sample. Samples were tested for 18 HPV genotypes using polymerase chain reaction (PCR) MassArray. Participants filled out sociodemographic and behavioral questionnaires. Prevalence ratios for HPV oral or cervicogenital prevalence by predictor variables were estimated in univariable log-binomial models. Analysis was conducted 2018-20. In the full cohort, baseline oral HPV prevalence was 10.0% for any detected genotype (among the 338 valid oral tests at baseline) and 6.5% for high-risk types, and cervicogenital prevalence was 20.0% and 10.8%, respectively (among the 130 first valid cervicogenital tests). Oral HPV prevalence did not vary by sex, with 10.5% of women and 9.0% of men having an infection. We found a high prevalence of oral and cervicogenital HPV infection in college-age participants reporting no lifetime sexual partners. Reporting a single recent partner was associated with a lower oral HPV prevalence (PR 0.39, 95% CI: 0.16, 0.96) than reporting no recent (but at least one ever) partner. No similar protective effect was seen for cervicogenital HPV. Both oral and cervicogenital prevalence increased with the number of recent partners for most sexual behaviors. We observed an ecological fallacy masking the direction of impact of vaccination on HPV prevalence in the full cohort compared to the college-aged and the age 23+ populations considered separately. Substance use was not significantly associated with oral or cervicogenital HPV infection. Many studies report substantially higher oral HPV infection prevalence in men than in women. That difference may not be uniform across populations in the US.

Accelerated hepatitis C virus kinetics but similar survival rates in recipients of liver grafts from living versus deceased donors.

This study tested the hypothesis that hepatitis C virus (HCV) RNA and core antigen levels rise more rapidly after liver transplantation (LT) in recipients of grafts from living donors (LD) versus deceased donors (DD). Eleven consecutive LD and 15 DD recipients were followed prospectively. Before LT, median HCV RNA levels were similar: 5.42 (LDLT) and 5.07 (DDLT) log(10) IU/mL (P = NS). During the first 7 hours after LT a trend toward a greater HCV RNA decrease in LDLT patients was seen, although they received fewer blood replacement products during surgery. HCV RNA levels rose more rapidly in LDLT patients between days 1 and 3 (P = .0059) and were higher in this group on days 2, 3, 4, and 5. Core antigen levels were significantly higher in LDLT patients on days 3 and 5, although they were similar before LT (P = NS). Alanine aminotransferase (ALT) values were higher among LDLT patients from 8 to 14 days and from 4 to 24 months. Two-year graft and patient survival were 73% for LDLT patients and 80% for DDLT patients (P = NS). In conclusion, viral load rose more rapidly in LD recipients and reached higher levels shortly after surgery. Greater ALT elevations were evident in the LDLT group, but survival rates were similar. The trend toward a greater initial viral load decrease in patients with LD grafts and the significantly sharper increase suggest that the liver plays a predominant role in both HCV clearance and replication.
