Social media analytics of overactive bladder posts: what do patients know and want to know?

OBJECTIVE

To assess women's knowledge, patient experience, and treatment decision making regarding overactive bladder (OAB) using digital ethnography.

METHODS

Online posts were identified using a data mining service. Two hundred randomized posts were reviewed and coded using grounded theory. We then applied a latent Dirichlet allocation (LDA) probabilistic topic modeling process to review the entire collection of identified posts.

RESULTS

A total of 2618 posts by 1867 unique users from 203 different websites were identified. Our analysis yielded six themes: the impact of OAB on quality of life, patient-physician interactions, online engagement, symptom management, patient knowledge acquisition, and alternative therapies.

CONCLUSION

Overall, online communities are a source of support for women to self-manage the OAB symptom complex and help overcome treatment pathway challenges. Digital ethnography provides insight into patient knowledge and barriers to patient-centered care, which are important to improve patient outreach. Additionally, we identify similar findings to prior work, indicating the reliability of studying social media.

Comparison of deep phenotyping features of UCPPS with and without Hunner lesion: A MAPP-II Research Network Study

OBJECTIVE

To use the phenotyping data from the MAPP-II Symptom Patterns Study (SPS) to compare the systemic features between urologic chronic pelvic pain syndrome (UCPPS) with Hunner lesion (HL) versus those without HL.

METHODS

We performed chart review on 385 women and 193 men with UCPPS who enrolled in the MAPP-II SPS. 223 had cystoscopy and documentation of HL status. Among them, 12.5% had HL and 87.5% did not.

RESULTS

UCPPS participants with HL were older, had increased nocturia, higher Interstitial Cystitis Symptom and Problem Indexes, and were more likely to report "painful urgency" compared with those without HL. On the other hand, UCPPS without HL reported more intense nonurologic pain, greater distribution of pain outside the pelvis, greater numbers of comorbid chronic overlapping pain conditions, higher fibromyalgia-like symptoms, and greater pain centralization, and were more likely to have migraine headache than those with HL. UCPPS without HL also had higher anxiety, perceived stress, and pain catastrophizing than those with HL. There were no differences in sex distribution, UCPPS symptom duration, intensity of urologic pain, distribution of genital pain, pelvic floor tenderness on pelvic examination, quality of life, depression, pain characteristics (nociceptive pain vs. neuropathic pain), mechanical hypersensitivity in the suprapubic area during quantitative sensory testing, and 3-year longitudinal pain outcome and urinary outcome between the two groups.

CONCLUSIONS

UCPPS with HL displayed more bladder-centric symptom profiles, while UCPPS without HL displayed symptoms suggesting a more systemic pain syndrome. The MAPP-II SPS phenotyping data showed that Hunner lesion is a distinct phenotype from non-Hunner lesion.

Accuracy of Urologic Conditions Portrayed on Grey's Anatomy

Despite the common prevalence of urologic diseases, studies have demonstrated that the general public often has little knowledge or insight into the field of urology or the role of an urologist. In this study, we investigated the context, frequency, and accuracy of urologic conditions on the television series Grey's Anatomy. We reviewed episodes from the first 15 seasons. Episodes with urologic references were then screened and the urologic conditions, outcomes, and treatments were recorded. We identified a total of only 21 urologic events across 15 seasons and 342 episodes of Grey's Anatomy. A total of 52% (11/21) of the conditions were related to external male genitalia. The portrayal of these conditions and the associated treatments were considered to be medically accurate within reason 62% (13/21) of the time. There is significant room for improvement to increase the portrayal of common urologic conditions and malignancies to improve the public's awareness and perception of our specialty.

Using Flow Disruptions to Examine System Safety in Robotic-Assisted Surgery: Protocol for a Stepped Wedge Crossover Design

BACKGROUND

The integration of high technology into health care systems is intended to provide new treatment options and improve the quality, safety, and efficiency of care. Robotic-assisted surgery is an example of high technology integration in health care, which has become ubiquitous in many surgical disciplines.

OBJECTIVE

This study aims to understand and measure current robotic-assisted surgery processes in a systematic, quantitative, and replicable manner to identify latent systemic threats and opportunities for improvement based on our observations and to implement and evaluate interventions. This 5-year study will follow a human factors engineering approach to improve the safety and efficiency of robotic-assisted surgery across 4 US hospitals.

METHODS

The study uses a stepped wedge crossover design with 3 interventions, introduced in different sequences at each of the hospitals over four 8-month phases. Robotic-assisted surgery procedures will be observed in the following specialties: urogynecology, gynecology, urology, bariatrics, general, and colorectal. We will use the data collected from observations, surveys, and interviews to inform interventions focused on teamwork, task design, and workplace design. We intend to evaluate attitudes toward each intervention, safety culture, subjective workload for each case, effectiveness of each intervention (including through direct observation of a sample of surgeries in each observational phase), operating room duration, length of stay, and patient safety incident reports. Analytic methods will include statistical data analysis, point process analysis, and thematic content analysis.

RESULTS

The study was funded in September 2018 and approved by the institutional review board of each institution in May and June of 2019 (CSMC and MDRH: Pro00056245; VCMC: STUDY 270; MUSC: Pro00088741). After refining the 3 interventions in phase 1, data collection for phase 2 (baseline data) began in November 2019 and was scheduled to continue through June 2020. However, data collection was suspended in March 2020 due to the COVID-19 pandemic. We collected a total of 65 observations across the 4 sites before the pandemic. Data collection for phase 2 was resumed in October 2020 at 2 of the 4 sites.

CONCLUSIONS

This will be the largest direct observational study of surgery ever conducted with data collected on 680 robotic surgery procedures at 4 different institutions. The proposed interventions will be evaluated using individual-level (workload and attitude), process-level (perioperative duration and flow disruption), and organizational-level (safety culture and complications) measures. An implementation science framework is also used to investigate the causes of success or failure of each intervention at each site and understand the potential spread of the interventions.

Using Digital Ethnography to Understand the Experience of Women With Pelvic Organ Prolapse

OBJECTIVE

To characterize the decision-making process and illness experience of women with pelvic organ prolapse (POP) using large-scale social media analysis.

METHODS

Digital ethnographic analysis of online posts identified through data mining was performed. Grounded theory methodology was applied to 200 posts via traditional hand coding. To supplement our qualitative approach, we applied a Latent Dirichlet Allocation probabilistic topic modeling process to review the entire data set of identified posts to ensure thematic saturation.

RESULTS

There were 3451 posts by 2088 unique users from 117 websites worldwide that were identified via social media data mining. We found that the anonymity of online forums allowed for information and support exchange among women with POP. Our analysis revealed that the exchange of online information aids in the decision-making process and, in some instances, appears to be the primary source of information. There was confusion about the anatomical and surgical complexities of prolapse. Our study also identified misconceptions, perceived risk factors, prevention methods, and management recommendations that were discussed online.

CONCLUSIONS

This large-scale online community-based analysis demonstrated the utility of social media to better understand women's experiences with POP. Thematic findings highlighted essential concerns and challenges involved in the surgical decision-making process and the understating of the anatomical complexity of sector defects, specifically to cystocele, rectocele, State specific defects.

Economic evaluation of elective cesarean versus vaginal delivery on cost of future pelvic floor disorders in the United States

AIM

To analyze the cost impact of cesarean versus vaginal delivery in the United States on the development of stress urinary incontinence (SUI) and pelvic organ prolapse (POP).

METHODS

We compared average cost of delivery method to the lifetime risk and cost of pelvic floor disorders (PFDs) in women < 65 years. Costs of maternal care, obtained from the MarketScan® database, included those incurred at delivery and 3 months post-partum. Future costs of PFDs included those incurred after delivery up to 65 years. Previously reported data on the prevalence of POP and SUI following cesarean and vaginal delivery was used to calculate attributable risk. An incremental cost of illness model was used to estimate costs for SUI. Direct surgical and ambulatory care costs were used to determine cost of POP.

RESULTS

Average estimated cost was $7089 for vaginal delivery and $9905 for cesarean delivery. The absolute risks for SUI and POP were estimated as 7% and 5%, respectively, following cesarean delivery, and 13% and 14%, respectively, following vaginal delivery. For SUI, average direct cost was $5642, indirect cost was $4208, and personal cost was $750. Average direct cost of POP surgery was $4658, and nonsurgical cost was $2220. The potential savings for reduced prevalence of SUI and POP in women who underwent cesarean delivery is estimated at $1255, but they incur an additional $2816 maternal care cost over vaginal delivery.

CONCLUSIONS

Although elective cesarean is associated with reduced prevalence of PFDs, the increased initial cost of cesarean delivery does not offset future cost savings.

Risk Factors for Intraoperative Bladder Perforation at the Time of Midurethral Sling Placement

OBJECTIVE

To evaluate patient-specific and perioperative factors that may be predictive of bladder perforation during midurethral sling placement.

METHODS

A retrospective chart review of women who underwent a midurethral sling procedure at our institution between 2013 and 2017 was completed. All cases with bladder perforation were included. Patient demographics and perioperative factors were explored for associations with perforation. Bivariate analysis was used to compare baseline characteristics between those with and without perforation. Logistic regression modeling was used to identify predictors of perforation and associations between bladder perforation and postoperative sequelae.

RESULTS

Four hundred and ten women had a urethral sling procedure at our institution between 2013 and 2017. Of these, 35 (9%) had evidence of bladder perforation on cystoscopy. This rate was higher for retropubic slings (15%) compared to transobturator slings (2%). Those with a perforation were younger (54 vs 61 years, P= .004) and had a lower average BMI (24.1 kg/m² vs 26.3 kg/m², P = .022). Other risk factors included lack of pre-existing apical prolapse (11% vs 4%, P = .012) and concomitant urethrolysis (27% vs 8%, P = .024). In multivariable analysis, age, BMI, and sling type were significantly associated with perforation. In univariate analysis, perforation was associated with postoperative lower urinary tract symptoms (OR 2.3, P = .21) and urinary tract infection within 30 days of surgery (OR 2.2, P = .047).

CONCLUSIONS

Intraoperative bladder perforation was associated with younger patient age and lower BMI. Additionally, bladder perforation is a risk factor for postoperative urinary tract infection and lower urinary tract symptoms.

Risk Factors for Surgical Shunting in a Large Cohort With Ischemic Priapism

BACKGROUND

Ischemic priapism is treated with a stepwise algorithm, but some patients may benefit from immediate shunt placement.

AIM

To identify risk factors for surgical shunt placement in a large series of patients with ischemic priapism.

METHODS

We identified all patients presenting to our institution with ischemic priapism from January 2010 to December 2018. Multivariable was performed to assess risk factors for surgical shunting. Receiver operating characteristic curve analysis (Youden Index) was used to assess which cutoff time for the duration of priapism was most predictive requiring shunting.

OUTCOMES

We assess risk factors for surgical shunting and what duration of priapism was most predictive of requiring a shunt.

RESULTS

We identified a total of 169 ischemic priapism encounters from 143 unique patients, of which 26 (15%) encounters resulted in a surgical shunt. Patients treated with a shunt had longer priapism durations than those without (median 36 vs 10 hours, P < .001). Independent predictors of a surgical shunt on multivariate logistic regression were the duration of priapism in hours (odds ratio: 1.05, 95% confidence interval: 1.02-1.10; P < .001) and history of prior priapism (odds ratio: 3.15, 95% confidence interval: 1.03-9.60; P = .045). Receiver operating characteristic curve analysis using priapism duration to predict the need for shunt generated an area under curve of 0.83. A duration of 24 hours correlated to a sensitivity of 0.77 and specificity of 0.90.

CLINICAL IMPLICATIONS

These results can be used to counsel future patients and assist in the decision-making process for providers.

STRENGTHS & LIMITATIONS

This is one of the largest series of priapism in the literature. Most (74%) of the priapism were due to intracavernosal injections so the results may not be generalizable to populations with different priapism etiologies.

CONCLUSION

In this study of 169 priapism encounters, we found that the priapism duration and history of prior priapism were independent predictors of surgical shunt placement. These results can aid urologists in the counseling and decision-making process of these challenging cases. Zhao H, Dallas K, Masterson J, et al.

Prospective study of a single-incision sling versus a transobturator sling in women with stress urinary incontinence: 3-year results

BACKGROUND

Long-term safety and efficacy data on use of single-incision slings in stress urinary incontinence are limited.

OBJECTIVE

To determine whether the single-incision sling Solyx (Boston Scientific, Marlborough, MA) is noninferior to the transobturator sling Obtryx II (Boston Scientific) in efficacy and safety for treatment of stress urinary incontinence. This 522 post-market surveillance study has been designed in response to a Food and Drug Administration request to evaluate improvement in stress urinary incontinence at 36 months following single-incision sling compared with baseline, as well as provide an assessment of mesh-related complications and subject-reported outcomes, relative to the transobturator sling control.

STUDY DESIGN

This prospective, nonrandomized, parallel cohort, multicenter postapproval study enrolled subjects to receive single-incision sling or transobturator sling. Study sites were assigned to a cohort group based on documented competency with the cohort device. Patient follow-up was 36 months to compare efficacy and adverse events for noninferiority. Inclusion criteria included stress predominant urinary incontinence, a positive cough stress test, and post-void residual ≤150 cc. Participants were ineligible if they had undergone previous stress urinary incontinence surgery or had a previous mesh complication. Primary endpoint was treatment success defined by composite negative cough stress test and subjective improvement in stress urinary incontinence using Patient Global Impression of Improvement at 36 months. Secondary endpoints included adverse events and indications for retreatment. Noninferiority margins of 15% and 10% were prespecified for the primary efficacy and safety endpoints. Data analysis was performed using intent-to-treat and per-protocol methods. Due to the observational nature of the study, a propensity score methodology was applied to account for differences in patient and surgeon characteristics between treatment groups. The study design and variables to be included in the propensity score model were reviewed and approved by Food and Drug Administration reviewers before outcome analyses were performed.

RESULTS

No evidence of imbalance in baseline characteristics was observed between groups after propensity score stratification in the 281 subjects. EBL (72.3±92 vs 73.1±63.9 mL, P=.786), time to spontaneous void (1.1±2 vs 0.8±2.8 days, P=.998), and time to discharge (0.7±0.7 vs 0.6±0.6 days, P=.524) were similar between groups. At 36 months, treatment success was 90.4% in the single-incision sling group and 88.9% in the transobturator sling group (P=.93). At 36 months, mesh-related complications were similar between groups (mesh exposure: 2.8% vs 5.0%, P=.38). Serious adverse events including pain during intercourse (0.7% vs 0%, P=1.00), pelvic pain (0.7% vs 0%, P=1.00), and urinary retention (2.8% vs 4.3%, P=.54) were similar between groups.

CONCLUSION

Single-incision sling was not inferior to transobturator sling for long-term treatment success of stress urinary incontinence. The rates of serious adverse events were acceptably low and similar between groups.

Treatment of urethral stricture disease in women: A multi‐institutional collaborative project from the SUFU research network

AIM

Female urethral stricture disease is rare and has several surgical approaches including endoscopic dilations (ENDO), urethroplasty with local vaginal tissue flap (ULT) or urethroplasty with free graft (UFG). This study aims to describe the contemporary management of female urethral stricture disease and to evaluate the outcomes of these three surgical approaches.

METHODS

This is a multi-institutional, retrospective cohort study evaluating operative treatment for female urethral stricture. Surgeries were grouped into three categories: ENDO, ULT, and UFG. Time from surgery to stricture recurrence by surgery type was analyzed using a Kaplan-Meier time to event analysis. To adjust for confounders, a Cox proportional hazard model was fit for time to stricture recurrence.

RESULTS

Two-hundred and ten patients met the inclusion criteria across 23 sites. Overall, 64% (n = 115/180) of women remained recurrence free at median follow-up of 14.6 months (IQR, 3-37). In unadjusted analysis, recurrence-free rates differed between surgery categories with 68% ENDO, 77% UFG and 83% ULT patients being recurrence free at 12 months. In the Cox model, recurrence rates also differed between surgery categories; women undergoing ULT and UFG having had 66% and 49% less risk of recurrence, respectively, compared to those undergoing ENDO. When comparing ULT to UFG directly, there was no significant difference of recurrence.

CONCLUSION

This retrospective multi-institutional study of female urethral stricture demonstrates that patients undergoing endoscopic management have a higher risk of recurrence compared to those undergoing either urethroplasty with local flap or free graft.

Outcomes of Prophylactic Mid-Urethral Sling at the Time of Robotic Sacrocolpopexy

OBJECTIVE

To compare outcomes of patients who underwent robotic sacrocolpopexy (RSC) with and without concomitant mid-urethral sling (MUS) placement for prophylaxis or treatment of preoperative stress urinary incontinence (SUI) METHODS: We performed a retrospective review of all patients without prior incontinence procedures who underwent RSC with or without MUS placement by 3 surgeons (JA, LA, KE) at a single institution from 2012 to 2017 for treatment of pelvic organ prolapse. Patients had a MUS placed for either documented SUI or prophylaxis of SUI. We compared patient characteristics, operative details, postoperative outcomes, and complications between the groups.

RESULTS

A total of 134 patients were identified. 58 (43%) had a MUS placed for documented SUI, 43 (32%) had prophylactic MUS, and 33 (25%) did not have a MUS placed. There were no differences in baseline characteristics between the 3 groups. Patients who did not have a MUS placed had less estimated blood loss (76.4 vs 63.8 vs 36.9 mL, P = .018) but no difference in operative time (P = .408), length of stay (P = .427), or postoperative urinary retention (P = .988). A total of 4 (7%) patients who had a MUS placed for SUI had persistent SUI postoperatively. There were 2 (5%) patients who had a MUS placed prophylactically and 4 (12%) patients who did not have a MUS that developed de novo SUI.

CONCLUSION

In this series, we demonstrate the safety and efficacy of prophylactic MUS placement at the time of RSC. Randomized studies evaluating concomitant prophylactic sling at time of robotic sacrocolpopexy could further guide preoperative patient counseling and decision-making.

Re-evaluation of birth trends and pregnancy complications among female urologists: Have we made any progress?

AIMS

Females are becoming surgeons at ever-increasing rates and doing so while many have or wish to have children. This study follows up on a 2007 effort to study the problems and conditions such women faced. We ask here if these challenges are different after a decade that included changes in working rules.

METHODS

A survey was sent to all female American Board of Urology diplomates. Birth trends, pregnancy complications, infertility service requirements, and satisfaction were evaluated in respondents (n = 183) and compared to the previous survey of female urologists who completed residency before August 2007 as well as Center for Disease Control data.

RESULTS

Seventy-six physicians completed the survey who were residents before 2007, while 107 replied who experienced residency after. The first group's average age was 50.2 and the second's 38.3. Overall, these women gave birth 6 to 7 years later than the US mean. Complications did not decrease, infertility occurred at similar levels, and both were higher than US norms. Length of maternity leave correlated with respondents' level of overall satisfaction. The most positive responses came from those with more than 8 weeks off (P = .002).

CONCLUSIONS

Women practicing in urology gave birth later, had greater fertility issues, used assisted reproductive technology (ART) more and reported a higher level of at least one complication during pregnancy than American women overall. Changes in hours and awareness of this issue have not made giving birth a healthier event for these physicians. Further investigation into factors other than work hours is needed.

The Applicant's Perspective on Urology Residency Interviews: A Qualitative Analysis

OBJECTIVE

To better understand what urology applicants look for on interview day and what they care about in selecting a residency program through an analysis of anonymous online posts about the urology interview process.

METHODS

We collected 3 years (2016-2018) of comments and posts from the Interview Impressions tab of the Urology Match Google Sheet for 133 urology residencies. Qualitative data analysis was performed using grounded theory methodology.

RESULTS

We identified 6 categories of themes on (1) interview day structure, (2) diverse faculty, (3) program culture, (4) surgical training, (5) research, and (6) program benefits. These themes appeared in comments for 77%-86% of the residency programs except for research which was present for 44% of the programs. The efficiency and structure of interview day are very important. Applicants also care about young and diverse fellowship-trained faculty across a wide breadth of subspecialties. They believe they are able to discern the program culture and collegiality between residents and faculty. Applicants want a balance of surgical and clinical training with a focus on robotics and surgical autonomy. Not all applicants are interested in research but those that are appreciate a strong support system. Finally, additional program benefits and the positives and negatives of the program's location are frequently discussed.

CONCLUSION

Analysis of anonymous social media posts can help improve the interview process for applicants and programs alike. Programs can also identify areas of improvement for residency training. Our findings provide additional insight towards the ultimate goal of improving the match process.

Identifying Opportunities to Improve Patient Experience With Sacral Neuromodulation: A Human Factors Approach

OBJECTIVES

To use a human factors approach to conduct a needs assessment of patient preparedness, education, device usability, and satisfaction regarding all stages of sacral neuromodulation therapy and identify opportunities for improvement. Sacral neuromodulation, though minimally invasive, involves an initial testing phase that requires active patient participation. This process is relatively complex and, if a patient does not receive adequate preprocedure education, can be difficult to conceptualize.

MATERIALS AND METHODS

Candidates were recruited to participate before undergoing staged sacral neuromodulation. Ten patients were observed, and their experiences were evaluated at 4 phases: (1) date of test implant (Stage I), (2) 5 days following Stage I, (3) date of permanent implant (Stage II), and (4) 3 months following Stage II. Administered questionnaires focused on preoperative preparedness, postoperative satisfaction, and usability.

RESULTS

While every patient reported that their symptoms were at least "a little better" postoperatively, they generally had difficulty understanding the risks of the planned procedure, did not know what to expect postoperatively and were unsatisfied with the preoperative materials. Patients struggled with adjusting the settings for their implant devices and usability was considered "below average." Despite overall objective success, 30% of patients indicated that they would not recommend this treatment to friends/family.

CONCLUSION

This pilot needs analysis demonstrates several opportunities for improvement in the experience of patients undergoing sacral neuromodulation. These findings highlight the opportunities for a multifaceted intervention to improve patient understanding through the testing phase.

Women's Experience with Stress Urinary Incontinence: Insights from Social Media Analytics

PURPOSE

We conducted a large-scale digital ethnographic analysis of anonymous online posts to capture the complete patient experience, knowledge and perceptions among women with stress urinary incontinence.

MATERIALS AND METHODS

Online posts were identified through data mining. Overall, 200 randomized posts were analyzed using grounded theory qualitative methods. To ensure full thematic discovery we also applied a Latent Dirichlet Allocation probabilistic topic modeling approach to the entire data set of identified posts. Latent Dirichlet Allocation topics are represented as a distribution of words, similar to a word cloud, which were manually reviewed to identify themes.

RESULTS

A total of 985 online posts by 762 unique users were extracted from 98 websites. There was significant overlap between the grounded theory and Latent Dirichlet Allocation identified themes. Our analysis suggests that these online communities help women manage the quality of life impact of their stress urinary incontinence, navigate specialty care and reach a decision regarding surgical vs nonsurgical management. Additionally, we identified risk factors, prevention strategies and treatment recommendations discussed online.

CONCLUSIONS

Findings demonstrated patient values that may influence decision making when seeking care for stress urinary incontinence and choosing a treatment. Social media interactions provide insight into patient behaviors that are important in order to improve patient centered care and decision making.

Characteristics, Burden, and Necessity of Inpatient Consults for Academic and Private Practice Urologists

OBJECTIVE

To compare differences in the characteristics and outcomes of inpatient consults between academic and private practice urologists.

MATERIALS AND METHODS

We performed a retrospective review of urology consults at a large tertiary-care hospital from June 1st, 2017 to June 30th, 2018. Patient demographics, timing of consult, location of consult, reasons for consult, requesting physicians, and procedures performed were analyzed and compared.

RESULTS

A total of 613 consults were identified. The most common consults were for a Foley catheter/suprapubic tube (16%), urinary retention (15%), kidney/bladder stones (11%), and hematuria (11%). Seventy-seven percent of the consults were seen in the day time and 79% were seen on the weekdays. One hundred and ten (18%) consults resulted in an operative intervention during the same admission. The others required a Foley catheter placement or suprapubic exchange (17%), bedside procedure (9%), or interventional radiology procedure (4%). The remaining 319 consults (52%) required no intervention and were considered potentially unnecessary. There were no differences in the timing of the consults and the need for intervention between academic and private practice urologists (P = .20). Only 37% of patients followed up as an outpatient. These potentially unnecessary consults resulted an annual loss of 265.8 hours for the urologists and $44,376.09 in excess health care costs.

CONCLUSION

Over half of inpatient urologic consultations required no urologic intervention and therefore represented potential overuse of urgent inpatient specialty care. This may contribute towards the growing epidemic of burnout in urology. Further work needs to be done to educate other hospital services and nurses to minimize these unnecessary consults.

Urinary fungi associated with urinary symptom severity among women with interstitial cystitis/bladder pain syndrome (IC/BPS)

PURPOSE

To correlate the presence of fungi with symptom flares, pain and urinary severity in a prospective, longitudinal study of women with IC/BPS enrolled in the MAPP Research Network.

METHODS

Flare status, pelvic pain, urinary severity, and midstream urine were collected at baseline, 6 and 12 months from female IC/BPS participants with at least one flare and age-matched participants with no reported flares. Multilocus PCR coupled with electrospray ionization/mass spectrometry was used for identification of fungal species and genus. Associations between "mycobiome" (species/genus presence, relative abundance, Shannon's/Chao1 diversity indices) and current flare status, pain, urinary severity were evaluated using generalized linear mixed models, permutational multivariate analysis of variance, Wilcoxon's rank-sum test.

RESULTS

The most specific analysis detected 13 fungal species from 8 genera in 504 urine samples from 202 females. A more sensitive analysis detected 43 genera. No overall differences were observed in fungal species/genus composition or diversity by flare status or pain severity. Longitudinal analyses suggested greater fungal diversity (Chao1 Mean Ratio 3.8, 95% CI 1.3-11.2, p = 0.02) and a significantly greater likelihood of detecting any fungal species (OR = 5.26, 95% CI 1.1-25.8, p = 0.04) in high vs low urinary severity participants. Individual taxa analysis showed a trend toward increased presence and relative abundance of Candida (OR = 6.63, 95% CI 0.8-58.5, p = 0.088) and Malassezia (only identified in 'high' urinary severity phenotype) for high vs low urinary symptoms.

CONCLUSION

This analysis suggests the possibility that greater urinary symptom severity is associated with the urinary mycobiome urine in some females with IC/BPS.

Priapism from Recreational Intracavernosal Injections in a High-Risk Metropolitan Community

INTRODUCTION

Recreational use of intracavernosal injections (ICIs) is a high-risk behavior that involves sharing of these agents by men without physician regulation.

AIM

To characterize the etiologies and outcomes of priapism at a Los Angeles metropolitan medical center to better understand patterns of usage of recreational ICIs and the public health implications of such practices.

METHODS

With institutional review board approval, we retrospectively reviewed all cases of priapism presenting to the emergency room of a Los Angeles tertiary medical center from 2010 to 2018. We compared outcomes between patients who presented with priapism after recreational ICI and patients who presented with other etiologies.

MAIN OUTCOME MEASURE

We describe patient characteristics, etiologies, and treatments of priapism at our institution.

RESULTS

We identified 169 priapism encounters by 143 unique patients. Recreational ICIs accounted for 82 of the 169 priapism encounters (49%). Patients who used recreational injections were younger than those who presented with other etiologies (43.5 years vs 47.5 years; P = .048) and had delayed presentations (median, 12 hours vs 8 hours; P < .0001). There was no statistical difference across groups in the proportion of patients requiring operative intervention (14.6% of recreational ICI users vs 16.1% of all other patients; P = .23). A total of 36 out of 72 patients who used recreational ICIs (50%) were HIV+.

CLINICAL IMPLICATIONS

Our study adds to the relatively sparse literature on priapism outcomes. We identify and describe a high-risk population that uses recreational intracavernosal injections.

STRENGTHS & LIMITATIONS

To our knowledge, this is the largest series of priapism encounters. However, the data are retrospective from a single institution, and there is a lack of long-term follow up.

CONCLUSION

A large proportion of priapism visits at our institution were attributed to recreational use of ICIs. This is a high-risk patient population that may not be aware of the risks of recreational ICIs and the consequences of priapism. Further effort should be made to increase public and physician awareness of this harmful practice. Zhao H, Berdahl C, Bresee C, et al. Priapism from Recreational Intracavernosal Injections in a High-Risk Metropolitan Community. J Sex Med 2019;16:1650-1654.

The misdiagnosis of interstitial cystitis/bladder pain syndrome in a VA population

AIMS

The complexity of Interstitial Cystitis/bladder Pain Syndrome (IC/BPS) has led to a great deal of uncertainty around the diagnosis and prevalence of the condition. Under the hypothesis that IC/BPS is frequently misdiagnosed, we sought to assess the accuracy of the ICD-9/ICD-10 code for IC/BPS using a national data set.

METHODS

Using the Veterans Affairs Informatics and Computing Infrastructure, we identified a random sample of 100 patients with an ICD-9/ICD-10 diagnosis of IC/BPS (595.1/N30.10) by querying all living patients in the Veterans Affairs (VA) system. We purposely sampled men and women equally to better understand gender-specific practice patterns. Patients were considered a correct IC/BPS diagnosis if they had two visits complaining of bladder-centric pain in the absence of positive urine culture at least 6 weeks apart. Patients were considered not to have IC/BPS if they had a history of pelvic radiation, systemic chemotherapy, metastatic cancer, or bladder cancer.

RESULTS

Of the 100 patients, 48 were female and 52 were male. Five had prior radiation, one had active cancer, and 10 had bladder cancer (all male), and an additional fifteen had insufficient records. Of the remaining 69 patients, 43% did not have IC/BPS. Of these patients who did not have IC/BPS, 43% complained only of overactive bladder (OAB) symptoms, which was more common in women (63%) than men (21%), P = .003.

CONCLUSIONS

In our small sample from a nationwide VA system, results indicate that IC/BPS has a high misdiagnosis rate. These findings shed light on the gender-specific diagnostic complexity of IC/BPS.

Human factors in robotic assisted surgery: Lessons from studies 'in the Wild'

This article reviews studies conducted "in the wild" that explore the "ironies of automation" in Robotic Assisted Surgery (RAS). Workload may be reduced for the surgeon, but increased for other team members, with postural stress relocated rather than reduced, and the introduction of a range of new challenges, for example, in the need to control multiple arms, with multiple instruments; and the increased demands of being physically separated from the team. Workflow disruptions were not compared with other surgeries; however, the prevalence of equipment and training disruptions differs from other types of surgeries. A consistent observation is that communication and coordination problems are relatively frequent, suggesting that the surgical team may need to be trained to use specific verbal and non-verbal cues during surgery. RAS also changes the necessary size of the operating room instrument cleaning processes. These studies demonstrate the value of clinically-based human factors engineers working alongside surgical teams to improve the delivery of RAS.
