RESUMO

Background and Objective: The coronavirus disease 2019 (COVID-19) public health emergency (PHE) resulted in rapid expansion and use of telehealth services. Regulatory and reimbursement flexibilities were put in place to ensure patients had continued access to care while the health system was overwhelmed by COVID-19 cases. These changes have allowed clinicians to use and researchers to evaluate telehealth in new ways. Methods: This narrative review focuses on highlighting telehealth research and evaluation that took place from March 2020 to February 2023 in the outpatient setting of the United States healthcare system. Key Content and Findings: The research conducted during the COVID-19 PHE shows that telehealth was primarily used as a substitute for in-person care, to maintain continuity of care for established patients, and has not had a negative impact on clinical outcomes or resulted in increasing healthcare costs. Conclusions: Studies show high patient and physician satisfaction, similar clinical outcomes and suggest that telehealth is used as a substitute for in-person care. The findings of this narrative review have direct implications for key stakeholders using telehealth now and beyond the COVID-19 pandemic. Patients, physicians and providers, healthcare leaders and administrators, as well as policymakers should consider how telehealth should continue to be reimbursed and regulated even as the COVID-19 PHE expired in May 2023.

RESUMO

Importance: As the field of medicine strives for equity in care, research showing the association of social determinants of health (SDOH) with poorer health care outcomes is needed to better inform quality improvement strategies. Objective: To evaluate the association of SDOH with prostate cancer-specific mortality (PCSM) and overall survival (OS) among Black and White patients with prostate cancer. Data Sources: A MEDLINE search was performed of prostate cancer comparative effectiveness research from January 1, 1960, to June 5, 2020. Study Selection: Two authors independently selected studies conducted among patients within the United States and performed comparative outcome analysis between Black and White patients. Studies were required to report time-to-event outcomes. A total of 251 studies were identified for review. Data Extraction and Synthesis: Three authors independently screened and extracted data. End point meta-analyses were performed using both fixed-effects and random-effects models. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed, and 2 authors independently reviewed all steps. All conflicts were resolved by consensus. Main Outcomes and Measures: The primary outcome was PCSM, and the secondary outcome was OS. With the US Department of Health and Human Services Healthy People 2030 initiative, an SDOH scoring system was incorporated to evaluate the association of SDOH with the predefined end points. The covariables included in the scoring system were age, comorbidities, insurance status, income status, extent of disease, geography, standardized treatment, and equitable and harmonized insurance benefits. The scoring system was discretized into 3 categories: high (≥10 points), intermediate (5-9 points), and low (<5 points). Results: The 47 studies identified comprised 1 019 908 patients (176 028 Black men and 843 880 White men; median age, 66.4 years [IQR, 64.8-69.0 years]). The median follow-up was 66.0 months (IQR, 41.5-91.4 months). Pooled estimates found no statistically significant difference in PCSM for Black patients compared with White patients (hazard ratio [HR], 1.08 [95% CI, 0.99-1.19]; P = .08); results were similar for OS (HR, 1.01 [95% CI, 0.95-1.07]; P = .68). There was a significant race-SDOH interaction for both PCSM (regression coefficient, -0.041 [95% CI, -0.059 to 0.023]; P < .001) and OS (meta-regression coefficient, -0.017 [95% CI, -0.033 to -0.002]; P = .03). In studies with minimal accounting for SDOH (<5-point score), Black patients had significantly higher PCSM compared with White patients (HR, 1.29; 95% CI, 1.17-1.41; P < .001). In studies with greater accounting for SDOH variables (≥10-point score), PCSM was significantly lower among Black patients compared with White patients (HR, 0.86; 95% CI, 0.77-0.96; P = .02). Conclusions and Relevance: The findings of this meta-analysis suggest that there is a significant interaction between race and SDOH with respect to PCSM and OS among men with prostate cancer. Incorporating SDOH variables into data collection and analyses are vital to developing strategies for achieving equity.

RESUMO

Ureteral injury may occur during abdominopelvic surgery given its anatomic path and proximity to surrounding organs. We present a case in which a patient required ureteral reimplantation following injury during a hysterectomy. The patient underwent a seemingly uncomplicated robotic ureteral reimplantation with ureteral stent placement. However, postoperative imaging demonstrated extension of the stent from the bladder to the right atrium. It appeared that the gonadal vein was reimplanted rather than the ureter. In a combined urology-vascular surgery case, gonadal vein implantation into the bladder was confirmed. Through-and-through access from the right internal jugular vein to the urethra was established. The ureteral stent was removed and the gonadal vein was embolized, with urology follow-up for planning and scheduling of ureteral reimplantation. Vascular involvement by ureteral stents has considerable risks and often requires further surgery. Ureteral injury can occur even in the hands of experienced surgeons and has a considerable impact on patients. Recognizing important anatomy and using operative techniques to differentiate from nearby structures, such as the gonadal vein, may help in preventing ureteral injury and assisting with repair of ureteral injury. Patient summary: We describe a case in which a patient had an injury to her ureter, the tube that transports urine from the kidney to the bladder. When trying to repair this, a blood vessel (the gonadal vein) instead of the ureter was accidentally connected to the bladder. We discuss the resulting complications and management, similar cases, and important anatomy concepts and surgical techniques to prevent this type of injury.

RESUMO

OBJECTIVE: To understand how the lack of a physical examination during new patient video visits can impact urological surgery planning during the COVID-19 pandemic. METHODS: We retrospectively reviewed 590 consecutive urology patients who underwent new patient video visits from March through May 2020 at a single academic center. Our primary outcome was procedural plan concordance, the proportion of video visit surgical plans that remained the same after the patient was seen in-person, either in clinic or on day of surgery. Median days between video and in-person visits were compared between concordant and discordant cases using the Mann-Whitney U test; P < .05 was significant. RESULTS: Overall, 195 (33%) were evaluated by new patient video visits and had a procedure scheduled, of which, 186 (95%) had concordant plans after in-person evaluation. Further, 99% of plans for in-office procedures and 91% for operating room procedures were unchanged. Four patients (2.1%) had surgical plans altered after changes in clinical course, two (1%) due to additional imaging, and three (1.5%) based on genitourinary examination findings. Days between video visit and in-person evaluation did not differ significantly in concordant cases (median 37.5 [IQR, 16 - 80.5]) as compared to discordant cases (median 58.0 [IQR, 20 - 224]; P = .12). CONCLUSIONS: Most surgical plans developed during new patient video visits remain unchanged after in-person examination. However, changes in clinical course or updated imaging can alter operative plans. Likewise, certain urologic conditions (eg, penile cancer) rely on the genitourinary examination to dictate surgical approach.

RESUMO

OBJECTIVE: To examine stakeholder perspectives regarding the lack of in-person externships and transition to a virtual urology residency interview format. The unprecedented disruption from the COVID-19 pandemic forced an abrupt pivot to a "virtual" Urology Match for the 2021 cycle. We aim for our study to inform ongoing deliberations on the future of the Urology Match. MATERIALS AND METHODS: Following Urology Match day in February 2021, two surveys were distributed by the Society of Academic Urologists to all applicants and program directors (PDs) who participated in the 2021 Urology Match. RESULTS: Overall, 192 of 481 applicants (40%) and 63 of 160 PDs (39%) responded. Most applicants (67%) were satisfied with their match outcomes, although unmatched applicants were significantly more likely to be unsatisfied than matched applicants (98% vs 9%, P <.0001). Most PDs were equally (79%) or more satisfied (13%) with their match outcomes compared with prior years. Nearly all applicants (93%) and PDs (94%) recommended retaining an in-person externship option. Most applicants (61%) and PDs (71%) felt their outcomes would not have changed with in-person interviews. Applicants and PDs were evenly split as to whether interviews should be conducted in-person or virtually in the future. CONCLUSION: The vast majority of applicants and PDs recommended retaining in-person externships for future match cycles despite high costs. In contrast, there was ambivalence amongst both groups of stakeholders regarding the format of interviews for future match cycles. We recommend virtual interviews moving forward to help alleviate the financial burden placed on applicants and increase equity.

RESUMO

BACKGROUND: Despite biomarker development advances, early detection of aggressive prostate cancer (PCa) remains challenging. We previously developed a clinical-grade urine test (Michigan Prostate Score [MiPS]) for individualized aggressive PCa risk prediction. MiPS combines serum prostate-specific antigen (PSA), the TMPRSS2:ERG (T2:ERG) gene fusion, and PCA3 lncRNA in whole urine after digital rectal examination (DRE). OBJECTIVE: To improve on MiPS with a novel next-generation sequencing (NGS) multibiomarker urine assay for early detection of aggressive PCa. DESIGN, SETTING, AND PARTICIPANTS: Preclinical development and validation of a post-DRE urine RNA NGS assay (Urine Prostate Seq [UPSeq]) assessing 84 PCa transcriptomic biomarkers, including T2:ERG, PCA3, additional PCa fusions/isoforms, mRNAs, lncRNAs, and expressed mutations. Our UPSeq model was trained on 73 patients and validated on a held-out set of 36 patients representing the spectrum of disease (benign to grade group [GG] 5 PCa). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The area under the receiver operating characteristic curve (AUC) of UPSeq was compared with PSA, MiPS, and other existing models/biomarkers for predicting GG ≥3 PCa. RESULTS AND LIMITATIONS: UPSeq demonstrated high analytical accuracy and concordance with MiPS, and was able to detect expressed germline HOXB13 and somatic SPOP mutations. In an extreme design cohort (n = 109; benign/GG 1 vs GG ≥3 PCa, stratified to exclude GG 2 cancer in order to capture signal difference between extreme ends of disease), UPSeq showed differential expression for T2:ERG.T1E4 (1.2 vs 78.8 median normalized reads, p < 0.00001) and PCA3 (1024 vs 2521, p = 0.02), additional T2:ERG splice isoforms, and other candidate biomarkers. Using machine learning, we developed a 15-transcript model on the training set (n = 73) that outperformed serum PSA and sequencing-derived MiPS in predicting GG ≥3 PCa in the held-out validation set (n = 36; AUC 0.82 vs 0.69 and 0.69, respectively). CONCLUSIONS: These results support the potential utility of our novel urine-based RNA NGS assay to supplement PSA for improved early detection of aggressive PCa. PATIENT SUMMARY: We have developed a new urine-based test for the detection of aggressive prostate cancer, which promises improvement upon current biomarker tests.

RESUMO

BACKGROUND: To evaluate the association between urinary MyProstateScore (MPS) and pathologic grade group (GG) at surgery in men diagnosed with GG1 prostate cancer (PCa) on biopsy. METHODS: Using an institutional biospecimen protocol, we identified men with GG1 PCa on biopsy and PSA ≤10 ng/ml who underwent radical prostatectomy (RP) at the University of Michigan. MPS was retrospectively calculated using prospectively collected, post-DRE urine samples. The primary outcome was upgrading on RP pathology, defined as GG ≥ 2. The associations of MPS, PSA, and PSA density (PSAD) with upgrading were assessed on univariable logistic regression, and the predictive accuracy of each marker was estimated by the area under the receiver operating characteristic curve (AUC). RESULTS: There were 52 men with urinary specimens available that met study criteria, based on biopsy Gleason Grade and specimen collection. At RP, 17 men (33%) had GG1 cancer and 35 (67%) had GG ≥ 2 cancer. Preoperative MPS was significantly higher in patients with GG ≥ 2 cancer at surgery (median 37.8 [IQR, 22.2-52.4]) as compared to GG1 (19.3 [IQR, 9.2-29.4]; P = 0.001). On univariable logistic regression, increasing MPS values were significantly associated with upgrading (odds ratio 1.07 per one-unit MPS increase, 95% confidence interval 1.02-1.12, P = 0.004), while PSA and PSAD were not significantly associated with upgrading. Similarly, the discriminative ability of the MPS model (AUC 0.78) for upgrading at RP was higher compared to models based on PSA (AUC 0.52) and PSAD (AUC 0.62). CONCLUSIONS: In men diagnosed with GG1 PCa who underwent surgery, MPS was significantly associated with RP cancer grade. In this limited cohort of men, these findings suggest that MPS could help identify patients with undetected high-grade cancer. Additional studies are needed to better characterize this association.

RESUMO

OBJECTIVE: To evaluate the complementary value of urinary MyProstateScore (MPS) testing and multiparametric MRI (mpMRI) and assess outcomes in patients with equivocal mpMRI. MATERIALS AND METHODS: Included patients underwent mpMRI followed by urine collection and prostate biopsy at the University of Michigan between 2015 -2019. MPS values were calculated from urine specimens using the validated model based on serum PSA, urinary PCA3, and urinary TMPRSS2:ERG. In the PI-RADS 3 population, the discriminative accuracy of PSA, PSAD, and MPS for GG≥2 cancer was quantified by the AUC curve. Decision curve analysis was used to assess net benefit of MPS relative to PSAD. RESULTS: There were 540 patients that underwent mpMRI and biopsy with MPS available. The prevalence of GG≥2 cancer was 13% for PI-RADS 3, 56% for PI-RADS 4, and 87% for PI-RADS 5. MPS was significantly higher in men with GG≥2 cancer [median 44.9, IQR (29.4 -57.5)] than those with negative or GG1 biopsy [median 29.2, IQR (14.8 -44.2); P <.001] in the overall population and when stratified by PI-RADS score. In the PI-RADS 3 population (n = 121), the AUC for predicting GG≥2 cancer was 0.55 for PSA, 0.62 for PSAD, and 0.73 for MPS. MPS provided the highest net clinical benefit across all pertinent threshold probabilities. CONCLUSION: In patients that underwent mpMRI and biopsy, MPS was significantly associated with GG≥2 cancer across all PI-RADS scores. In the PI-RADS 3 population, MPS significantly outperformed PSAD in ruling out GG≥2 cancer. These findings suggest a complementary role of MPS testing in patients that have undergone mpMRI.

RESUMO

Use of serum prostate-specific antigen (PSA) testing for early detection of prostate cancer appears to reduce cancer-specific mortality. Due to the limited specificity of PSA for clinically significant [Grade Group (GG) ≥2] cancer, however, screening carries substantial risks, including frequent unnecessary prostate biopsies and overdetection of non-aggressive cancers. To that end, serum and urine biomarkers with improved specificity for GG ≥2 cancer have been proposed for clinical use following PSA. In the current article, we present clinical validation data for five such biomarkers: PHI, 4Kscore, SelectMDx, ExoDx, and MPS. For all studies, we specify the study population (overall biopsy referral vs. pre-specified PSA ranges), previous biopsy status (biopsy-naïve vs. previous negative biopsy), and the proportion of subjects diagnosed with GG ≥2 cancer. Outcomes include test performance characteristics: sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV). Published data were used to compute the number of unnecessary biopsies avoided and number of GG ≥2 cancers missed if the biomarker had been used clinically to select for prostate biopsy. The evidence review is preceded by a primer on these and other clinically-relevant summary statistics.

RESUMO

BACKGROUND AND OBJECTIVES: Surgical oncology patients are vulnerable to persistent opioid use. As such, we aim to compare opioid prescribing to opioid consumption for common surgical oncology procedures. METHODS: We prospectively identified patients undergoing common surgical oncology procedures at a single academic institution (August 2017-March 2018). Patients were contacted by telephone within 6 months of surgery and asked to report their opioid consumption and describe their discharge instructions and opioid handling practices. RESULTS: Of the 439 patients who were approached via telephone, 270 completed at least one survey portion. The median quantity of opioid prescribed was significantly larger than consumed following breast biopsy (5 vs. 2 tablets of 5 mg oxycodone, p < .001), lumpectomy (10 vs. 2 tablets of 5 mg oxycodone, p < .001), and mastectomy or wide local excision (20 tablets vs. 2 tablets of 5 mg oxycodone, p < .001). The majority of patients reported receiving education on taking opioids, but only 27% received instructions on proper disposal; 82% of prescriptions filled resulted in unused opioids, and only 11% of these patients safely disposed of them. CONCLUSIONS: This study demonstrates that opioid prescribing exceeds consumption following common surgical oncology procedures, indicating the potential for reductions in prescribing.

RESUMO

PURPOSE: The MyProstateScore test was validated for improved detection of clinically significant (grade group ≥2) prostate cancer relative to prostate specific antigen based risk calculators. We sought to validate an optimal MyProstateScore threshold for clinical use in ruling out grade group ≥2 cancer in men referred for biopsy. MATERIALS AND METHODS: Biopsy naïve men provided post-digital rectal examination urine prior to biopsy. MyProstateScore was calculated using the validated, locked multivariable model including only serum prostate specific antigen, urinary prostate cancer antigen 3 and urinary TMPRSS2:ERG. The MyProstateScore threshold approximating 95% sensitivity for grade group ≥2 cancer was identified in a training cohort, and performance was measured in 2 external validation cohorts. We assessed the 1) overall biopsy referral population and 2) population meeting guideline based testing criteria (ie, prostate specific antigen 3-10, or <3 with suspicious digital rectal examination). RESULTS: Validation cohorts were prospectively enrolled from academic (977 patients, median prostate specific antigen 4.5, IQR 3.1-6.0) and community (548, median prostate specific antigen 4.9, IQR 3.7-6.8) settings. In the overall validation population (1,525 patients), 338 men (22%) had grade group ≥2 cancer on biopsy. The MyProstateScore threshold of 10 provided 97% sensitivity and 98% negative predictive value for grade group ≥2 cancer. MyProstateScore testing would have prevented 387 unnecessary biopsies (33%), while missing only 10 grade group ≥2 cancers (3.0%). In 1,242 patients meeting guideline based criteria, MyProstateScore ≤10 provided 96% sensitivity and 97% negative predictive value, and would have prevented 32% of unnecessary biopsies, missing 3.7% of grade group ≥2 cancers. CONCLUSIONS: In a large, clinically pertinent biopsy referral population, MyProstateScore ≤10 provided exceptional sensitivity and negative predictive value for ruling out grade group ≥2 cancer. This straightforward secondary testing approach would reduce the use of more costly and invasive procedures after screening with prostate specific antigen.

RESUMO

OBJECTIVE: To evaluate the association of the MyProstateScore (MPS) urine test on the decision to undergo biopsy in men referred for prostate biopsy in urology practice. METHODS: MPS testing was offered as an alternative to immediate biopsy in men referred to the University of Michigan for prostate biopsy from October 2013 through October 2016. The primary endpoint was the decision to perform biopsy. The proportion of patients undergoing biopsy was compared to predicted risk scores from the Prostate Cancer Prevention Trial risk calculator (PCPTrc). Analyses were stratified by the use of multiparametric magnetic resonance imaging (mpMRI). The associations of PCPTrc, MPS, and mpMRI with the decision to undergo biopsy were explored in a multivariable logistic regression model. RESULTS: Of 248 patients, 134 (54%) proceeded to prostate biopsy. MPS was significantly higher in biopsied patients (median 29 vs14, P < .001). The use of biopsy was strongly associated with MPS, with biopsy rates of 26%, 38%, 58%, 90%, and 85% in the first through fifth quintiles, respectively (P < .001). MPS association with biopsy persisted upon stratification by mpMRI. On multivariable analysis, MPS was strongly associated with the decision to undergo biopsy when modeled as both a continuous (odds ratio [OR] 1.05, 95%; confidence interval [CI] 1.04-1.08; <.001) and binary (OR 7.76, 95%; CI 4.14-14.5; P < .001) variable. CONCLUSION: Many patients (46%) undergoing clinical MPS testing as an alternative to immediate prostate biopsy were able to avoid biopsy. Increasing MPS was strongly associated with biopsy rates. These findings were robust to use of mpMRI.

RESUMO

OBJECTIVES: Prostate cancer (CaP) staging traditionally includes computed tomography (CT) and technetium-99m bone scintigraphy (BS) for assessment of lymph node (LN) and bone metastases, respectively. In recent years, multiparametric magnetic resonance imaging (mpMRI) has been used in diagnostic assessment of CaP. We sought to compare the accuracy of mpMRI to CT and BS for pretreatment staging. MATERIALS AND METHODS: Using the Michigan Urological Surgery Improvement Collaborative registry, we identified men undergoing pretreatment mpMRI in addition to CT and/or BS in 2012 to 2018. Imaging reports were classified as positive, negative, or equivocal for detection of LN and bone metastases. A best value comparator (BVC) was used to adjudicate metastatic status in the absence of pathologic data. mpMRI accuracy was calculated using pessimistic (equivocal=positive) and optimistic (equivocal = negative) interpretations. We compared the diagnostic performance of mpMRI, CT, and BS in detecting metastases. RESULTS: In total, 364 men underwent CT and mpMRI, and 646 underwent BS and mpMRI. Based on the BVC, 52 men (14%) harbored LN metastases and 38 (5.9%) harbored bone metastases. Sensitivity of mpMRI for LN metastases was significantly higher than CT (65-73% vs 38%, P < 0.005), and specificity of mpMRI and CT were 97% to 99% and 99% (P = 0.2-0.4), respectively. For bone metastases, BS sensitivity was 68% as compared to 42% to 71% (P = 0.02-0.83) for mpMRI. Specificity for bone metastases was 95% to 99% across all modalities. CONCLUSIONS: Using statewide data, mpMRI appears superior to CT and comparable to BS for detection of LN and bone metastases, respectively. Pretreatment mpMRI may obviate the need for additional staging imaging.

RESUMO

STUDY DESIGN: Systematic review. OBJECTIVE: We systematically reviewed the level of clinical evidence presented at Cervical Spine Research Society annual meetings from 2008 through 2017. SUMMARY OF BACKGROUND DATA: The Cervical Spine Research Society is dedicated to advancing knowledge of the cervical spine to promote evidence-based care. Research presented at these meetings impacts clinical practice. METHODS: A total of 774 paper abstracts presented at Cervical Spine Research Society (CSRS) annual meetings were independently assessed by two reviewers. Reviewers designated a clinical level of evidence (LOE) to each included abstract from level I to level IV based on criteria set forth by the Oxford Centre for Evidence-Based Medicine. Reviewer agreement was assessed using Cohens Kappa coefficient (k) and disagreements were discussed until a consensus was reached. Wilcoxon rank sum test was used to assess for differences in LOE grades. Chi-squared testing was used to assess nonrandom changes in level of evidence and in excluded studies. RESULTS: A total of 583 abstracts were included. Over the last 10 CSRS meetings, 5.15% of presentations were level I, 27.8% level II, 27.4% level III, and 39.6% level IV. The average LOE from 2008 to 2017 was 3.02 (median = 3). Additionally, 49.7% were therapeutic studies, 37.6% prognostic studies, and 12.7% diagnostic studies. When comparing the first 5 years (2008-2012) to the last 5 years (2013-2017), we observed a significant increase in Level II (P = 0.007) evidence and a corresponding decrease in level IV evidence (P < 0.001). The average LOE improved from 3.14 (2008-2012) to 2.91 (2013-2017); there was a significant improvement in LOE between the two periods (P = 0.001). CONCLUSION: Emphasis on evidence-based medicine within cervical spine research has positively influenced the clinical level of evidence disseminated at CSRS annual meetings between 2008 and 2017.
