Introduction: An estimated 18% of Canadians have overactive bladder (OAB), with approximately 24% of those reporting difficulty adhering to pharmacotherapy. To date, there has been no investigation into barriers facing sacral neuromodulation (SNM) as treatment for OAB in Canada.

Methods: Current Canadian Urological Association members were invited to participate in an anonymous survey. Data collected included open-ended and Likert scale responses addressing barriers to referral for SNM. Qualitative analysis used a Theoretical Domains Framework (TDF), while quantitative responses are reported using descriptive statistics.

Results: A response rate of 20.4% (n=142) was obtained. Most respondents believed SNM was underused (n=82, 57.7%) compared to only 6.3% (n=9) who believed it was used adequately. The most commonly cited reasons for not offering SNM were lack of availability (n=85, 59.9%), expertise (n=49, 34.5%), and funding (n=26, 18.3%). Participants were neutral regarding confidence to appropriately recommend SNM to patients (median 3, interquartile range [IQR] 2-4) and were not confident to manage patient care and issues related to SNM devices (median 2, IQR 1-3). On thematic analysis using the TDF, the most prevalent barriers to SNM care were related to infrastructure and resources. A lack of trained experts and lack of knowledge related to SNM use were also commonly identified barriers.

Conclusions: In this first study exploring urologist-perceived barriers to SNM referral for medically refractory OAB in Canada, urologists acknowledge that SNM implantation is underused but did not feel confident in recommending SNM appropriately. A lack of trained experts and poor funding were also identified as major barriers to SNM referral.

Introduction: Computed tomography (CT) is associated with increased cost and exposure to radiation when compared to ultrasound (US) in patients with renal colic. Consequently, a 2014 Choosing Wisely recommendation states US should be used over CT in uncomplicated presentations in patients under age 50. The objective of this study was to describe imaging practice patterns in Ontario among patients presenting with renal colic and the relationship between initial imaging modality, subsequent imaging, and burden of care indicators.

Methods: This is a population-based study of patients who presented with renal colic in Ontario from 2003-2019 using administrative data. Patients were assessed according to their first imaging modality during their index visit. Descriptive statistics and Chi-squared test were used to examine differences between these groups. The primary outcome was the need for subsequent imaging. Secondary outcomes were length of renal colic episode, days to surgery, and number of emergency department (ED ) and primary care visits during the renal colic episode. Univariate and multivariable logistic regression models were used.

Results: A total of 429 060 patients were included in the final analysis. Of those, 50.5% (216 747) had CT as their initial imaging modality, 20% (84 672) had US, and 3% (13 643) had both on the same day. Subsequent imaging was obtained in 40.7% of those who had CT as the initial imaging, compared to 43% in those who had US and 43% who had both. Of those who initially had an US, 38% went on to have at least one CT during their renal colic episode, including those who had CT on the same day as initial US, while 62% were able to avoid CT altogether. In contrast, 17% had a repeat CT after an initial CT at the time of presentation. The overall use of US increased from 15% to 31% during the study period. The length of the renal colic episode was slightly longer in those who had a CT first compared to US in multivariable models (adjusted risk ratio [ARR ] 1.005, 95% confidence interval [CI] 1.000-1.009); however, the time to surgery was less in those who had a CT first (ARR 0.831, 95% CI 0.807-0.856). Fewer ED and family physician visits were seen in those who had an initial CT.

Conclusions: In patients with renal colic in Ontario, approximately half have CT as the initial imaging modality despite US being recommended in uncomplicated presentations. While US use remains low, its use doubled during this study period, demonstrating an encouraging trend. Those who have US first can often avoid subsequent CT.

Introduction: Individuals with spina bifida (SB) may experience negative health outcomes because of an informal transition from pediatric to adult care that results in using the emergency room (ER ) for non-acute health problems.

Methods: We conducted a retrospective, population-based cohort study of all people with SB in Ontario, Canada turning 18 years old between 2002 and 2011. These patients were followed for five years before and after age 18. Primary outcome was the annual rate of ER visits. Secondary outcomes included rates of hospitalization, surgery, primary care, and specialist outpatient care. We estimated the association between age and primary and secondary outcomes using negative binomial growth curve models, adjusting for patient-level baseline covariates.

Results: Among the 1215 individuals with SB, there was no trend of ER visits seen with increasing age (relative risk [RR ] 0.99, 95% confidence interval [CI] 0.98-1.02); however, there was a significant increase in the rate of ER visits associated with turning 18 years (RR 1.14, 95% CI 1.03-1.27). Turning 18 years old was also associated with a decreased rate of hospital admissions (RR 0.79, 95% CI 0.66-0.95) and no change in surgeries (RR 0.80, 95% CI 0.64-1.02). Visits to primary care physicians remained stable over the same period (RR 0.96, 95% CI 0.90-1.01), while visits to SB-focused specialists decreased after age 18 (RR 0.81, 95% CI 0.75-0.87).

Conclusions: In patients with SB, the rate of ER visits increased significantly at 18 years old, while hospital admissions and specialist physician visits decreased at the same time. Models of transitional care can aim to reduce non-urgent ER visits and facilitate regular specialist care.
