The who, what, and how of teamwork research in medical operating rooms: A scoping review.

Despite the importance of teamwork in the operating room (OR), teamwork can often be conflated with teamwork components (e.g., communication, cooperation). We reviewed the existing literature pertaining to OR teamwork to understand which teamwork components have been assessed. Following PRISMA guidelines for scoping reviews, 4,233 peer-reviewed studies were identified using MEDLINE and Embase. Eighty-seven studies were included for synthesis and analysis. Using the episodic model of teamwork as an organizing framework, studies were grouped into the following teamwork categories: (a) transition processes (e.g., goal specification), (b) action processes (e.g., coordination), (c) interpersonal processes (e.g., conflict management), (d) emergent states (e.g., psychological safety), or (e) omnibus topics (a combination of higher-order teamwork processes). Results demonstrated that action processes were most frequently explored, followed by transition processes, omnibus topics, emergent states, and interpersonal processes. Although all studies were framed as investigations of teamwork, it is important to highlight that most explored only one or a few constructs under the overarching umbrella of teamwork. We advocate for enhanced specificity with descriptions of OR teamwork, reporting practices pertaining to interprofessional demographics and outcomes, and increased diversity in study design and surgery type to advance understanding of teamwork and its implications.

Ambulatory percutaneous nephrolithotomy is safe and effective in patients with extended selection criteria.

INTRODUCTION: Ambulatory percutaneous nephrolithotomy (PCNL) has been limited to highly selected patients. The objective of our study was to compare complication and stone-free rates after ambulatory PCNL in standard selection criteria vs. extended criteria patients. METHODS: We conducted a retrospective review of prospective data on all patients who underwent ambulatory PCNL at one academic center from 2007-2018. Extended criteria patients were defined as one or more of: age >75 years, body mass index (BMI) >30 kg/m2, American Society of Anesthesiologists (ASA) score >2, bilateral stones, solitary kidney, transplant kidney, complete staghorn calculi, stone burden >40 mm, multiple tracts, or prior nephrostomy tubes/stents. Primary outcomes were complication rates (Clavien-Dindo classification) and stone-free rates. RESULTS: We identified 118 patients, of which 92 (78%) met extended criteria. Mean BMI was 31 kg/m2 and 45% were ASA 3 or higher. Mean sum maximum stone diameter was 24 mm. Multiple stones were present in 25%, bilateral stones in 7%, and complete staghorn stones in 4% of patients. There was no difference in complication (12% vs. 18%, p=0.56), emergency department visit (12% vs. 18%, p=0.56), or re-admission (4% vs. 5%, p=1) rates between standard and extended criteria patients, respectively. Of the complications, 85% were Clavien-Dindo grade 1. Stone-free rates were not different between standard (84%) and extended (83%) criteria patients (p=1). No extended criteria variables were associated with complications in multivariable analysis. CONCLUSIONS: Complication and stone-free rates were not different between standard and extended selection criteria patients undergoing ambulatory PCNL. This data indicates that many of the preoperative patient and stone factors that have previously been used as exclusion criteria for ambulatory PCNL are not strictly necessary.

The association of gender and persistent opioid use following an acute pain event: A retrospective population based study of renal colic.

INTRODUCTION: This study aims to explore gender-related differences in persistent opioid use following an acute pain episode and evaluate potential explanatory variables. METHODS: This retrospective population-based study using administrative databases included all opioid-naïve patients in Ontario with renal colic between 2013 and 2017. The primary outcome was to assess any association between persistent opioid use at 3-6 months by gender. Key confounding covariates and explanatory variables examined included both care- and patient-related factors, specifically past evidence of mental health diagnoses. RESULTS: The dataset of 64,240 males and 37,656 females demonstrated that 8.7% of males and 9.6% of females had evidence of persistent opioid use 3-6 months after presentation (OR 1.11, 95% CI 1.05, 1.17). Females had a higher incidence of mental health services utilization [44.5% vs 29.6% (p<0.001)] and were more likely to be on a provincial disability program [5.1% vs 3.8% (p<0.001)]. Age, income quintile, mental health diagnoses and dose of opioid prescribed were associated with the primary outcome in both genders. On adjusted analysis for multiple confounding and explanatory variables, females were still more likely than males to demonstrate persistent opioid use (OR 1.07, 95% CI 1.01, 1.13) with even more pronounced associations at 1-2 years. INTERPRETATION: After controlling for key covariates, females are at slightly higher risk of demonstrating long term opioid use following an episode of renal colic. Evidence of prior mental health service utilization and acute colic care did not appear to significantly explain these observations.

Increased risk of new persistent opioid use in pediatric and young adult patients with kidney stones.

INTRODUCTION: Adolescents and young adults are a vulnerable patient population for development of substance use disorder. However, the long-term impact of opioid prescribing in young adult patients with renal colic is not known. Our objective was to describe rates of opioid prescription and identify risk factors for persistent opioid use in patients age 25 years or younger with renal colic from kidney stones. METHODS: Using previously validated, linked administrative databases, we performed a population-based, retrospective cohort study of opioid-naive patients age 25 years or younger with renal colic between July 1, 2013 and September 30, 2017 in Ontario. All family practitioner, urgent care, and specialist visits in the province were captured. Our primary outcome was persistent opioid use, defined as filling a prescription for an opioid between 91 and 180 days after initial visit. Ontario uses a narcotic monitoring system, which captures all opioids dispensed in the province. RESULTS: Of the 6962 patients identified, 56% were prescribed an opioid at presentation and 34% of those were dispensed more than 200 oral morphine equivalents. There was persistent opioid use in 313 (8.1%) patients who filled an initial opioid prescription. In adjusted analysis, those prescribed an opioid initially had a significantly higher risk of persistent opioid use (odds ratio [OR] 1.85; 95% confidence interval [CI] 1.50-2.29) and opioid overdose (OR 3.45; 1.08-11.04). There was a dose-dependent increase in risk of persistent opioid use with escalating initial opioid dose. History of mental illness (OR 1.32; 1.02-1.71) and need for surgery (OR 1.71; 1.24-2.34) were also associated with persistent opioid use. CONCLUSIONS: Among patients with kidney stones age 25 years or younger, filling an opioid prescription after presentation is associated with an increased risk of persistent opioid use 3-6 months later and a higher risk of serious long-term complications, such as opioid overdose.

Celebrating 75 years.

INTRODUCTION: Following the introduction of shock wave lithotripsy (SWL), ureteroscopy (URS), and percutaneous nephrolithotomy (PCNL), the subspecialty of endourology was born in the late 1970s. The purpose of this study was to report milestones in Canadian endourology, highlighting Canada's contributions to the field. METHODS: A review of the literature was performed from the late 1970s to the present. The literature review included bibliographic and digital resources. Additionally, records and recollections by various individuals were used, including some who were directly involved. RESULTS: Endourology was born in Canada when SWL, URS, and PCNL emerged as minimally invasive treatment options for stones in the early to mid-1980s. According to our research, the first PCNL was performed at the University of Toronto in 1981. Dr. Joachim Burhenne, a Harvard-trained radiologist from Germany, first used extracorporeal SWL in Canada at the University of British Columbia (UBC) for the treatment of biliary stones. Treatment for urinary tract stones followed at UBC and Dalhousie University. The first worldwide use of the holmium laser for lithotripsy of urinary tract calculi took place at the University of Western Ontario. Other endourology milestones in Canada include the formation of the Canadian Endourology Group and the emergence of the Endourological Society-accredited fellowship programs at the University of Toronto and Western University in the 1990s. Canada hosted the 21st and 35th World Congress of Endourology and Shock Wave Lithotripsy annual meeting in Montreal and Vancouver, respectively. CONCLUSIONS: Canadian urologists have led many advances in SWL, URS, and PCNL over the past four decades and, for a relatively small community, have made significant contributions to the field. Through the training of the next generation of endourologists at Canadian institutions, the future of endourology in Canada is bright.

Persistent Opioid Use Among Patients with Urolithiasis: A Population based Study.

BACKGROUND: Urolithiasis can result in acute, short-lived pain for which opioids are often prescribed. The risk of persistent opioid use following an initial presentation for urolithiasis is unknown. OBJECTIVE: To describe rates of opioid prescription and identify risk factors for persistent opioid use among patients with urolithiasis. DESIGN, SETTING, AND PARTICIPANTS: This was a population-based study of all patients diagnosed with urolithiasis in Ontario between 2013 and 2017 using administrative databases. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was persistent opioid use, defined as dispensing of opioids between 91 and 180 d after presentation. Multivariable logistic regression and Cox proportional hazard models were used to identify factors associated with outcomes. RESULTS AND LIMITATIONS: Of 101 896 previously opioid-naïve patients, 66% were prescribed opioids at diagnosis and 41% of those were dispensed more than 200 oral morphine equivalents (OMEs). For those patients prescribed opioids, 9% had continued use. In adjusted analysis, the number of health care visits and having a stone intervention were associated with a higher risk of persistent opioid use (p< 0.0001). Total OME dispensed at presentation was highly associated with persistent use: for >300 OME the odds ratio (OR) was 1.59 (95% confidence interval [CI] 1.41-1.79). Among those who had an intervention, the number and type of procedure were also associated with persistent use: the OR for shockwave lithotripsy compared to ureteroscopy was 1.65 (95% CI 1.42-1.92). This study is limited by the accuracy of the diagnostic and procedural administrative codes available. CONCLUSIONS: The majority of urolithiasis patients were prescribed opioids and 9% of previously opioid-naïve patients exhibited persistent opioid use 91-180 d after their initial urolithiasis visit. PATIENT SUMMARY: In this study we found that 9% of patients prescribed opioids at presentation for kidney stones filled an additional prescription 3-6 mo later. Risk factors for this continued use included a higher dose of opioids prescribed in the initial period and the type of kidney stone surgery.

Techniques - Ultrasound-guided percutaneous nephrolithotomy: How we do it.

Ultrasonography has emerged as an alternative to fluoroscopy for image-guided percutaneous nephrolithotomy (PCNL) in many countries. Compared to fluoroscopy-guided PCNL (F-PCNL), ultrasound-guided PCNL (US-PCNL) is easier to learn and reduces radiation exposure to patients and providers. Despite these advantages, uptake of ultrasound-guided PCNL (US-PCNL) in Canada has been almost nonexistent, largely because it is not incorporated into urologists' training. In this article, we seek to familiarize Canadian urologists with this approach by describing our step-by-step technique for US-PCNL. Additionally, we provide keys to successful implementation of this technique.

Impact of a training program on the performance of graduating Canadian residents on a national urology exam: Results of the last 20 years.

INTRODUCTION: Many factors impact the performance of graduating residents on certification exams. It is thought that most factors are related to the individual candidate's ability, motivation, and work ethic. Less understood, however, is whether a training program has any impact on the preparation and performance of its graduates on certification exams. We present 20 years of results of a national preparatory exam that all graduating residents complete about three months before the Royal College of Physicians and Surgeons of Canada (RCPSC) qualifying urology exam. This exam, known colloquially as QUEST, aims to simulate the RCPSC exam with written and oral components. We aimed to analyze the impact of a training program on the performance of its residents. METHODS: A retrospective review of exam results from 1997-2016 was conducted. During that time, 495 candidates from all 12 Canadian urology training programs undertook the exam. The performance of graduating residents from each individual program was grouped together for any given year. The different programs were anonymized, as the aim of this study is to assess the impact of a training program and not to rate the different programs. Statistical analysis using one-way ANOVA was conducted. RESULTS: All training programs fall within one standard deviation of the mean for the written component, the oral component, and the overall score. The residents of four training programs had statistically better scores than the overall mean of the written component. The residents of three out of these four training programs also had statistically better scores than the overall mean of the oral component and the overall results of the exam. CONCLUSIONS: Most Canadian training programs prepare their residents adequately for this simulated certification exam in urology. However, there are some training programs that consistently prepare graduating residents to outperform their peers.

The impact of positive and negative intraoperative surgeons' leadership behaviors on surgical team performance.

BACKGROUND: The effects of surgeons' leadership on team performance are not well understood. The purpose of this study was to examine the simultaneous effects of transformational, passive, abusive supervision and over-controlling leadership behaviors by surgeons on surgical team performance. METHODS: Trained observers attended 150 randomly selected operations at a tertiary care teaching hospital. Observers recorded instances of the four leadership behaviors enacted by the surgeon. Postoperatively, team members completed validated questionnaires rating team cohesion and collective efficacy. Multiple regression analyses were computed. Data were analyzed using the complex modeling function in MPlus. RESULTS: Surgeons' abusive supervision was negatively associated with psychological safety (unstandardized B = -0.352, p < 0.01). Both surgeons' abusive supervision (unstandardized B = -0.237, p < 0.01), and over-controlling leadership (unstandardized B = -0.230, p < 0.05) were negatively associated with collective efficacy. CONCLUSIONS: This study is the first to assess the simultaneous effects of surgeons' positive and negative leadership behaviors on intraoperative team performance. Significant effects only surfaced for negative leadership behaviors; transformational leadership did not positively influence team performance.
