Accurate Documentation Contributes to Guideline-concordant Surveillance of Nonmuscle Invasive Bladder Cancer: A Multisite Department of Veterans Affairs Study.

OBJECTIVE: To determine if accurate documentation of bladder cancer risk was associated with a clinician surveillance recommendation that is concordant with AUA guidelines among patients with nonmuscle invasive bladder cancer (NMIBC). METHODS: We prospectively collected data from cystoscopy encounter notes from four Department of Veterans Affairs (VA) sites to ascertain whether they included accurate documentation of bladder cancer risk and a recommendation for a guideline-concordant surveillance interval. Accurate documentation was a clinician-recorded risk classification matching a gold standard assigned by the research team. Clinician recommendations were guideline-concordant if the clinician recorded a surveillance interval that was in line with the AUA guideline. RESULTS: Among 296 encounters, 75 were for low-, 98 for intermediate-, and 123 for high-risk NMIBC. 52% of encounters had accurate documentation of NMIBC risk. Accurate documentation of risk was less common among encounters for low-risk bladder cancer (36% vs 52% for intermediate- and 62% for high-risk, P < .05). Guideline-concordant surveillance recommendations were also less common in patients with low-risk bladder cancer (67% vs 89% for intermediate- and 94% for high-risk, P < .05). Accurate documentation was associated with a 29% and 15% increase in guideline-concordant surveillance recommendations for low- and intermediate-risk disease, respectively (P < .05). CONCLUSION: Accurate risk documentation was associated with more guideline-concordant surveillance recommendations among low- and intermediate-risk patients. Implementation strategies facilitating assessment and documentation of risk may be useful to reduce overuse of surveillance in this group and to prevent unnecessary cost, anxiety, and procedural harms.

Perioperative Mobile Telehealth Program for Post-Prostatectomy Incontinence: A Randomized Clinical Trial.

PURPOSE: Perioperative pelvic floor muscle training can hasten recovery of bladder control and reduce severity of urinary incontinence following radical prostatectomy. Nevertheless, most men undergoing prostatectomy do not receive this training. The purpose of this trial was to test the effectiveness of interactive mobile telehealth (mHealth) to deliver an evidence-based perioperative behavioral training program for post-prostatectomy incontinence. MATERIALS AND METHODS: This was a 3-site, 2-arm, randomized trial (2014-2019). Men with prostate cancer scheduled to undergo radical prostatectomy were randomized to a perioperative behavioral program (education, pelvic floor muscle training, progressive exercises, bladder control techniques) or a general prostate cancer education control condition, both delivered by mHealth for 1-4 weeks preoperatively and 8 weeks postoperatively. The primary outcome was time to continence following surgery measured by the ICIQ (International Consultation on Incontinence Questionnaire) Short-Form. Secondary outcomes measured at 6, 9 and 12 months included Urinary Incontinence Subscale of Expanded Prostate Cancer Index Composite; pad use; International Prostate Symptom Score QoL Question and Global Perception of Improvement. RESULTS: A total of 245 men (ages 42-78 years; mean=61.7) were randomized. Survival analysis using the Kaplan-Meier estimate showed no statistically significant between-group differences in time to continence. Analyses at 6 months indicated no statistically significant between-group differences in ICIQ scores (mean=7.1 vs 7.0, p=0.7) or other secondary outcomes. CONCLUSIONS: mHealth delivery of a perioperative program to reduce post-prostatectomy incontinence was not more effective than an mHealth education program. More research is needed to assess whether perioperative mHealth programs can be a helpful addition to standard prostate cancer care.

Comparative Cost Analysis: Teleurology vs Conventional Face-to-Face Clinics.

OBJECTIVE: To compare costs associated with teleurology vs face-to-face clinic visits for initial outpatient hematuria evaluation. MATERIALS AND METHODS: The analysis included 3 cost domains: transportation, clinic operations, and patient time. Transportation cost was based on standard government travel reimbursement. Clinic staff cost was based on hourly salary plus fringe benefits. For a face-to-face clinic encounter, patient time included time spent for travel, parking, walking to and from clinic, checking in and checking out, nursing evaluation, urologic evaluation, laboratory, and waiting. Patient time cost was based on the Federal minimum wage. Provider and laboratory times were excluded from the cost analysis as these were similar for both encounters. RESULTS: We included 400 hematuria evaluations: 300 teleurology and 100 face-to-face. Both groups had similar median age (63 vs 64 years, P = .48) and median travel distance/time (58 vs 54 miles, P = .19; 94 vs 82 minutes, P = .09, respectively). Average patient time was greater for face-to-face encounters (266 vs 70 minutes teleurology, P < .001). Transportation was the primary driver of overall costs ($83.47 per encounter), followed by patient time ($32.87/encounter) and clinic staff cost ($18.68/encounter). The average cost per encounter was $135.02 for face-to-face clinic vs $10.95 for teleurology (P < .001) exclusive of provider and laboratory times. Cost savings associated with each telehematuria encounter totaled $124.07. CONCLUSION: Teleurology offers considerable cost savings of $124 per encounter for the initial evaluation of hematuria compared to face-to-face clinic. With 1.5 million annual hematuria encounters nationally, implementation of teleurology for hematuria evaluation offers cost savings approaching $200 million per year.

Patient Acceptance of Teleurology via Telephone vs Face-to-Face Clinic Visits for Hematuria Consultation at a Veterans Affairs Medical Center.

INTRODUCTION: We evaluated the experience and preferences of patients undergoing hematuria consultation via teleurology compared to a conventional face-to-face clinic visit. METHODS: Patients evaluated for hematuria with teleurology or face-to-face clinic visit were surveyed regarding their experience and preferences. The survey consisted of 27 questions evaluating overall acceptance and satisfaction (8 questions), impact factors (17) and preference (2). RESULTS: A total of 450 patients participated in the survey at a 2-to-1 ratio (300 via teleurology, 150 via face-to-face visits). Overall, patient satisfaction level was higher with teleurology compared to face-to-face clinic visits (mean score 9.2 vs 8.4, p <0.0001). This finding was observed in all 8 domains (acceptance, efficiency, convenience, friendliness, quality of interview, communication and care, provider professionalism and privacy protection, all p <0.001). Transportation related issues were the most common underlying reason that influenced patient opinion, with at least 1 transportation factor being reported by 280 of 300 teleurology patients (93.3%) and 133 of 150 patients seen face-to-face (88.7%). Clinic operation and provider interaction factors similarly impacted patient satisfaction and preference. Time to access was significantly better for teleurology (12 days) compared to face-to-face clinics (72 days, p <0.001). Overall incidence of bladder cancer was 5.6% (25 of 450 patients), which was observed in 6.3% of the teleurology group (19 of 300) and 4.0% of the face-to-face group (6 of 150, p = 0.386). CONCLUSIONS: Patients prefer teleurology to face-to-face clinic visits for the initial evaluation of hematuria. Teleurology positively impacts compliance and access by potentially eliminating common challenges facing patients, and by improving efficiency, convenience and flexibility.

Urologist Use of Cystoscopy for Patients Presenting With Hematuria in the United States.

OBJECTIVE: To evaluate the prevalence of cystoscopy and factors associated with use among hematuria patients presenting to urologists, based on results from a nationally representative survey. METHODS: Using the National Ambulatory Medical Care Survey (2006-2012), we identified outpatient visits to urologists for hematuria, and excluded visits associated with benign diagnoses (eg, urinary tract infection). Our primary outcome was performed or planned cystoscopy. We hypothesized that major risk factors (ie, gross hematuria, tobacco use, age >50, male gender) would be associated with increased cystoscopy use. We used multivariable logistic regression to evaluate the relationship between available patient, provider, and practice setting factors and use of cystoscopy. RESULTS: Among an estimated 10.8 million hematuria visits to urologists, cystoscopy was planned or performed after 34.7% of visits (95% confidence interval [CI] 30.7-39.0). Patients with gross hematuria (adjusted odds ratio 2.17, 95% CI 1.28-3.69) and current tobacco users (adjusted odds ratio 2.48, 95% CI 1.40-4.39) had over twice the odds of undergoing cystoscopy compared to patients without those risk factors. We estimated that there are over 20,000 missed cancer cases annually among moderate- and high-risk hematuria patients, and nearly 230,000 excess cystoscopy cases annually for patients with near-zero cancer risk. CONCLUSION: Despite guidelines emphasizing the importance of cystoscopy in hematuria evaluations, just over one-third of patients diagnosed with hematuria by urologists undergo this procedure. There also appears to be considerable misallocation of cystoscopy for hematuria patients, with excessive use among low-risk patients and significant potential for missed cancer cases among those at higher risk of malignancy.

Implementation of a Tele-urology Program for Outpatient Hematuria Referrals: Initial Results and Patient Satisfaction.

OBJECTIVE: To report on results from a new tele-urology pathway for managing hematuria consults, including a survey of patient attitudes and satisfaction with such a program. Recent guideline changes have relaxed the definition of microscopic hematuria and may have significantly increased the number of hematuria evaluations. MATERIALS AND METHODS: Patients referred to the Atlanta Veterans Administration Medical Center with hematuria were scheduled for a tele-urology clinic encounter utilizing a telephone call to obtain hematuria-related clinical information via a standardized algorithm. At subsequent cystoscopy, patients were evaluated with a 29-question survey regarding overall acceptance and satisfaction of the clinic (8 questions) and impact factors (21 questions). RESULTS: One hundred fifty veterans participated in the survey. Median time from consult request to appointment was 12 days and thereafter to cystoscopy was 16 days. Patients reported high acceptance and overall satisfaction with telephone evaluation; mean scores exceeded 9 out of 10 for overall satisfaction, efficiency, convenience, friendliness, care quality, understandability, privacy, and professionalism. When presented with a choice, nearly all patients (98%) preferred telephone-based encounters to face-to-face clinic visits. Underlying negative factors responsible for patients' preferences included transportation-related issues (97%) and logistical clinic issues (65%). Ninety-seven percent of patients reported high-quality evaluation. CONCLUSION: Patients report high acceptance and satisfaction with telephone clinics as a mechanism for expedited hematuria evaluation, primarily due to avoiding barriers related to transportation and clinical operations, as well as a perceived high quality of evaluation. Telephone appointments have potential to positively impact healthcare access and productivity.

Impact of remote monitoring and supervision on resident training using new ACGME milestone criteria.

INTRODUCTION: The study objective was to determine the impact of remote monitoring and supervision (RMS) in integrated endourology suites (IES) on residents achieving endoscopic training milestones. MATERIALS AND METHODS: Twenty-one urology residents evaluated RMS in IES using a 25-question survey. IES provided audio-visual communication for faculty to supervise residents remotely. Questionnaire used a linear visual scale of 1-10 to assess acceptability (8 questions), impact on training (10 questions), supervision level (1 question), and pre- and post-training milestone self-assessments (6 questions). Improvements in Patient Care Milestone #7 (upper/lower tract endoscopic procedures) and Patient Care Milestone #9 (office-based procedures) were analyzed. RESULTS: Twenty-one urology residents (out of potential 23) evaluated RMS in IES using a 25-question survey (91.3% response rate). Overall RMS acceptability and satisfaction was high (mean score = 9.1/10) with a majority (95.2%) feeling comfortable being alone with the patient. Residents reported positively on the following parameters: autonomy without compromising safety (8.7), supervision level (8.6), achieving independence (8.4), education quality (8.3), learning rate (8.1), clinical decision-making (8.0), and reducing case numbers to achieve proficiency (7.6). Residents perceived no issues with under- or over-supervision, and a majority (76.2%) expressed that RMS should be standard of training in residency programs. Residents reported mean level increases of 2.5 and 2.8 (out of 5) in Patient Care Milestones for endoscopic procedures and office-based procedures, respectively (p < 0.0001). CONCLUSIONS: RMS in integrated endourology suites may enhance resident education and endoscopic training. The study demonstrated an increase in competency levels reported by residents trained using RMS.

The Value of Pathological Examination of the Foreskin Following Circumcision.

INTRODUCTION: We determined the clinical impact and value of routine histopathological examination of the foreskin following circumcision. METHODS: We performed a retrospective study of 225 consecutive adult circumcisions. Indications for circumcision were categorized as benign or malignant based on preoperative clinical evaluation. Histopathological results were similarly classified as benign or malignant. Preoperative clinical impression and postoperative histological diagnosis were compared and reported as concordant (in agreement) or discordant (in disagreement). The cost impact of histopathology examination was analyzed with respect to study findings. RESULTS: Of the 225 patients 209 (92.9%) had clinically benign disease on preoperative evaluation and 16 (7.1%) had foreskin lesions suspicious for malignancy. Mean age was 57.0 years (range 23 to 92). Patients were younger in the benign group than in the malignant group (56.5 vs 62.8 years, p = 0.018). Black patients represented 65.8% of the study population and were similarly distributed between the 2 groups (p = 0.405). There was no statistical difference in patient height, weight, body mass index or comorbidities between the 2 groups. Preoperative clinical impression and postoperative histological diagnosis were concordant in all 209 patients in the benign group. Of the 16 patients suspected to have malignant disease preoperatively 9 (56.2%) had malignancy and 7 (43.8%) had benign disease on histopathological examination. CONCLUSIONS: Routine histological examination of a foreskin specimen in the absence of clinical suspicion for malignancy appears to have diminished benefit in the setting of benign preoperative indications. Omitting this traditional practice in patients with benign surgical indications may positively impact health care costs without compromising quality of care.

Incidence and clinical characteristics of lower urinary tract symptoms as a presenting symptom for patients with newly diagnosed bladder cancer.

PURPOSE: The incidence of lower urinary tract symptoms (LUTS) as the sole presenting symptom for bladder cancer has traditionally been reported to be low. The objective of this study was to evaluate the prevalence and clinical characteristics of newly diagnosed bladder cancer patients who presented with LUTS in the absence of gross or microscopic hematuria. MATERIALS AND METHODS: We queried our database of bladder cancer patients at the Atlanta Veteran's Affairs Medical Center (AVAMC) to identify patients who presented solely with LUTS and were subsequently diagnosed with bladder cancer. Demographic, clinical, and pathologic variables were examined. RESULTS: 4.1% (14/340) of bladder cancer patients in our series presented solely with LUTS. Mean age and Charlson Co-morbidity Index of these patients was 66.4 years (range = 52-83) and 3 (range = 0-7), respectively. Of the 14 patients in our cohort presenting with LUTS, 9 (64.3%), 4 (28.6%), and 1 (7.1%) patients presented with clinical stage Ta, carcinoma in Situ (CIS), and T2 disease. At a median follow-up of 3.79 years, recurrence occurred in 7 (50.0%) patients with progression occurring in 1 (7.1%) patient. 11 (78.6%) patients were alive and currently disease free, and 3 (21.4%) patients had died, with only one (7.1%) death attributable to bladder cancer. CONCLUSIONS: Our database shows a 4.1% incidence of LUTS as the sole presenting symptom in patients with newly diagnosed bladder cancer. This study suggests that urologists should have a low threshold for evaluating patients with unexplained LUTS for underlying bladder cancer.

Re-examination of the natural history of high-grade T1 bladder cancer using a large contemporary cohort.

INTRODUCTION: High-grade T1 (HGT1) bladder cancer represents a clinical challenge in that the urologist must balance the risk of disease progression against the morbidity and potential mortality of early radical cystectomy and urinary diversion. Using two non-muscle invasive bladder cancer (NMIBC) databases, we re-examined the rate of progression of HG T1 bladder cancer in our bladder cancer populations. MATERIALS AND METHODS: We queried the NMIBC databases that have been established independently at the Atlanta Veterans Affairs Medical Center (AVAMC) and the University of Pennsylvania to identify patients initially diagnosed with HGT1 bladder cancer. Demographic, clinical, and pathologic variables were examined as well as rates of recurrence and progression. RESULTS: A total of 222 patients were identified; 198 (89.1%) and 199 (89.6%) of whom were male and non-African American, respectively. Mean patient age was 66.5 years. 191 (86.0%) of the patients presented with isolated HG T1 disease while 31 (14.0%) patients presented with HGT1 disease and CIS. Induction BCG was utilized in 175 (78.8%) patients. Recurrence occurred in 112 (50.5%) patients with progression occurring in only 19 (8.6%) patients. At a mean follow-up of 51 months, overall survival was 76.6%. Fifty two patients died, of whom only 13 (25%) patient deaths were bladder cancer related. CONCLUSIONS: In our large cohort of patients, we found that the risk of progression at approximately four years was only 8.6%. While limited by its retrospective nature, this study could potentially serve as a starting point in re-examining the treatment algorithm for patients with HG T1 bladder cancer.

Scrotal abscess as initial presentation of squamous cell carcinoma.

We report a case of scrotal squamous cell carcinoma in a 67-year-old man that presented as a recurrent nonhealing scrotal abscess. Radical scrotectomy and bilateral simple orchiectomy were performed. A pudendal thigh flap was used for wound closure. To our knowledge, this is the first report of its use after radical surgery for scrotal cancer. The clinical features, staging, and treatment of scrotal squamous cell carcinoma are reviewed. In this report, we highlight the importance of including scrotal cancer in the differential diagnosis when evaluating a scrotal abscess.

Elective versus routine postoperative clinic appointments after circumcisions performed under local anesthesia.

OBJECTIVE: To evaluate a model of elective postoperative clinic appointments after a minor urological procedure and to compare it to the traditional practice of routine appointments. METHODS: A total of 104 consecutive patients undergoing adult circumcision under local anesthesia were divided into 2 groups; group A (n = 45) received routine postoperative clinic appointments and group B (n = 59) were given the option to make an appointment on an as-needed basis. Both groups received detailed postoperative instructions on the early signs of symptoms of potential adverse events. The 2 groups were compared regarding demographics, clinical profile, postoperative recovery, and outcome. RESULTS: Group A patients ("routine appointments") were younger (51 vs 60 years, P <.0001) and included fewer African Americans (57.8% vs 78.0%, P <.03) compared to group B patients ("elective appointments"). Postoperative clinic appointments were categorized as unnecessary in 84.4% (38/45) and 71.1% (42/59) of the patients in groups A and B, respectively. Of the remaining 17 patients in group B who elected to make an appointment, only 1 patient (1.7%) had a true procedure-related issue that justified the visit and required management. Overall, there was no statistical difference between the 2 groups with regard to the number of patients with perceived postoperative issues (P = .36). CONCLUSION: The traditional practice of routine clinic appointments after uncomplicated adult circumcision is medically unnecessary and provides little value in the majority of cases. The practice of open access elective postoperative evaluation based on clearly defined clinical criteria is efficacious, safe, convenient, and enhances resource utilization.

Formalin disinfection of biopsy needle minimizes the risk of sepsis following prostate biopsy.

PURPOSE: We describe a simple and effective method to reduce the risk of infection after prostate biopsy. MATERIALS AND METHODS: A total of 1,642 consecutive prostate biopsy procedures during a 4-year period (2008 to 2012) were included in the study. Inclusion criteria consisted of pre-biopsy negative urine culture, bisacodyl enema and fluoroquinolone antibiotics (3 days). Formalin (10%) was used to disinfect the needle tip after each biopsy core. All patients were monitored for post-biopsy infection. The rate of infection was compared to that of a historical series of 990 procedures. Two ex vivo experiments were conducted to test the disinfectant effectiveness of formalin against fluoroquinolone resistant Escherichia coli, and another experiment was performed to quantitate formalin exposure. RESULTS: Post-biopsy clinical sepsis with positive urine and blood cultures (quinolone resistant E. coli) developed in 2 patients (0.122%). Both patients were hospitalized, treated with intravenous antibiotics and had a full recovery without long-term sequelae. Mild uncomplicated urinary infection developed in 3 additional patients (0.183%). All were treated with outpatient oral antibiotics and had a complete recovery. The overall rate of urinary infection and sepsis using formalin disinfection was approximately a third of that of a prior series (0.30% vs 0.80%, p=0.13). Ex vivo experiments showed a complete lack of growth of fluoroquinolone resistant E. coli on blood and MacConkey agars after exposure to formalin. The amount of formalin exposure was negligible and well within the safe parameters of the Environmental Protection Agency. CONCLUSIONS: Formalin disinfection of the biopsy needle after each prostate biopsy core is associated with a low incidence of urinary infection and sepsis. This technique is simple, effective and cost neutral.

A +20% adjustment in the computed tomography measured ureteral length is an accurate predictor of true ureteral length before ureteral stent placement.

PURPOSE: The correct length of a ureteral stent is important in minimizing postplacement discomfort and stent migration. We describe and validate a method to accurately measure the ureteral length. MATERIALS AND METHODS: The ureteral length in 48 patients undergoing ureteral stent placement for urolithiasis was measured by computed tomography (CT) (total thickness of axial slices between the ureteropelvic junction and ureterovesical junction) and adjusted up by 20%. The adjusted CT measurement of ureteral length was compared with direct intraoperative measurement using scatter plot and Pearson correlation coefficient. Correlation coefficients were also calculated between intraoperative ureteral length and various body habitus measurements such as the height, weight, and waist circumference. RESULTS: Median patient age was 62 years. The median stone diameter was 7.5 mm (1-20). The ratio of left- to right-sided stones was 2:1. The stone location was in the proximal ureter in 45.8%, distal ureter in 37.5%, kidney in 10.4%, and midureter in 6.3%. Symptoms included adnominal/flank pain (93.8%) followed by nausea/vomiting (39.6%) and gross hematuria (16.7%). Median creatinine was 1.4 (0.8-3.6 mg/dl) and median WBC was 8.6 (2.8-17.6). The median ureteral length was 25.8 cm (19.2-29.4) on the CT scan and 25.5 cm (19.0-29.0) on the intraoperative measurement (p=0.57). The Pearson correlation coefficient between the two measurements was 0.979. In contrast, the height, weight, and waist circumference correlated poorly with intraoperative ureteral length measurements (r=0.34, 0.19, and 0.40, respectively). CONCLUSION: CT-measured ureteral length adjusted up by 20% is a reliable method to accurately measure the true ureteral length. This method is superior to traditional indirect methods that rely on body habitus measurements.

Evaluation of novel formula of PSA, age, prostate volume, and race in predicting positive prostate biopsy findings.

OBJECTIVE: To develop a formula that incorporates age, prostate volume, race, and prostate-specific antigen (PSA) level into a single score for prostate cancer detection. MATERIALS AND METHODS: We developed a PSA-age volume (AV) score by multiplying the patient age by the prostate volume and dividing it by the PSA level. The PSA-AV was developed using 1000 prostate biopsy specimens and was validated on 318 internal and 4406 external biopsy specimens. RESULTS: We analyzed 1000 biopsy specimens (mean age 63 ± 8 years, 63% white and 35% black, mean PSA 6.8 ± 4 ng/mL, mean prostate volume 41 ± 18 cm(3), mean PSA-AV 485 ± 304). Of the 1000 biopsy specimens, 556 (55.6%) had positive findings. A lower PSA-AV score correlated with a greater cancer risk (R(2) = 0.91). A PSA-AV score of 700 had a sensitivity and specificity of 87% and 35%, respectively. These values matched or exceeded the sensitivity and specificity for age-adjusted PSA level and a PSA cutoff of 4 ng/mL. Compared with using the age-adjusted PSA level, using a score of 700 increased the number of biopsies by 64 and detected 62 more cancers. Using a PSA-AV cutoff of 700, rather than a PSA cutoff of 4 ng/mL, led to 16 fewer biopsies with 7 additional cancers detected. Our data were internally and externally validated. CONCLUSION: According to our data, a PSA-AV score has shown to be a useful formula for predicting positive biopsy findings. A PSA-AV score of 700 is useful in ruling out cancer in younger patients and patients with small prostates, and in ruling in cancer in older patients and patients with a large prostate.

Remote monitoring and supervision of urology residents utilizing integrated endourology suites-a prospective study of patients' opinions.

PURPOSE: To report on integrated endourology suites (IES), remote monitoring and supervision (RMS) of urology residents and to evaluate patients' opinions, acceptance, and satisfaction level with IES and RMS. PATIENTS AND METHODS: Patients undergoing flexible cystoscopy in the IES with RMS were surveyed using a questionnaire. All procedures were performed by junior urology residents (UR-1 level) using RMS. Patients were studied using a nine-question survey to evaluate their comfort level, acceptance, and level of satisfaction with RMS. Six questions used a scale of 1 to 10 (1=strongly disagree; 10=strongly agree), and the remaining three questions solicited a "yes" or "no" response. RESULTS: 100 patients were studied (59% Caucasians, 40% African Americans, and 1% Hispanic). Median age was 63 years. The highest level of education was middle school in 2% of patients, high school in 55%, undergraduate in 33%, and postgraduate in 10%. Patients scored a mean of 9.50/10 (highly satisfactory) regarding their comfort with RMS; 96% scored ≥ 7, 4% scored 5 to 6, and none scored <5. Patients were satisfied having a urology resident perform the procedure (9.48/10), other residents and medical students watch the procedure (9.41/10), a video camera in the room (9.40/10), and two-way sound communication (9.40/10). None perceived compromise to their privacy or quality of care. CONCLUSIONS: RMS in IES is highly acceptable to patients undergoing endoscopic procedures. RMS has the potential to positively impact residency training, efficiency, regulatory compliance, safety, and productivity.
