Advanced Practice Providers, Urology Workforce Challenges, and Reviews in Urology

Kenneth A. Mitchell

In 2015, the American Urological Association published the Consensus Statement on Advanced Practice Providers (APPs) with the goal of providing up-to-date information on the training of APPs, the scope of practice legislation, and examples of APPs in urologic practices.1 This statement was co-written by an experienced team of physicians and APPs whose purpose was to provide a unique and collaborative perspective on urology APPs. The paper was inspired by a report from an American Urological Association ad hoc committee assembled in 2008, which concluded that there were substantial workforce shortages in urology and that physician assistants and advanced practice registered nurses would provide the “best solution” for the declining urology workforce.2 In 2009, reports estimated that there were 3.1 urologists per 100 000 people in the United States and that urology was the second-oldest surgical subspecialty, with a workforce median age of 52.5 years.2 A published update in 2021, which used data from 2018, revealed that there were 3.89 urologists per 100 000 people in the United States, with 65% of urologists reporting that they were “interested” in the integration and use of APPs; 72.5% of urologists reported already incorporating an APP into their practice, accounting for nearly 41% of a physician (ie, MD or DO) full-time equivalent.2 More recent data showed the use of APPs was lowest in practices with the youngest and oldest subgroups of urologists and was highest in urban urology practices, which represent groups most likely to be affected initially due to the disproportionate geographical urology patient population density.

The 4Kscore® Test Reduces Prostate Biopsy Rates in Community and Academic Urology Practices

There is significant concern regarding prostate cancer screening because of the potential for overdiagnosis and overtreatment of men who are discovered to have abnormal prostate specific antigen (PSA) levels and/or digital rectal examination (DRE) results. The 4Kscore® Test (OPKO Diagnostics, LLC) is a blood test that utilizes four kallikrein levels plus clinical information in an algorithm to calculate an individual’s percentage risk (< 1% to > 95%) for aggressive prostate cancer (Gleason score ≥ 7) on prostate biopsy. The 4Kscore Test, as a follow-up test after abnormal PSA and/or DRE test results, has been shown to improve the specificity for predicting the risk of aggressive prostate cancer and reduce unnecessary prostate biopsies. A clinical utility study was conducted to assess the influence of the 4Kscore Test on the decision to perform prostate biopsies in men referred to urologists for abnormal PSA and/or DRE results. The study population included 611 patients seen by 35 academic and community urologists in the United States. Urologists ordered the 4Kscore Test as part of their assessment of men referred for abnormal PSA and/or DRE test results. Results for the patients were stratified into low risk (< 7.5%), intermediate risk (7.5%-19.9%), and high risk (≥ 20%) for aggressive prostate cancer. The 4Kscore Test results influenced biopsy decisions in 88.7% of the men. Performing the 4Kscore Test resulted in a 64.6% reduction in prostate biopsies in patients; the actual percentage of cases not proceeding to biopsy were 94.0%, 52.9%, and 19.0% for men who had low-, intermediate-, and high-risk 4Kscore Test results, respectively. A higher 4Kscore Test was associated with greater likelihood of having a prostate biopsy (P < 0.001). Among the 171 patients who had a biopsy, the 4Kscore risk category is strongly associated with biopsy pathology. The 4Kscore Test, as a follow-up test for an abnormal PSA and/or DRE results, significantly influenced the physician and patient shared decision in clinical practice, which led to a reduction in prostate biopsies while increasing the probability of detecting aggressive cancer.

Venous Thromboembolism in Urologic Surgery: Prophylaxis, Diagnosis, and Treatment

Treatment Update

Kevin R RiceStephen A BrassellDavid G McLeod

Venous thromboembolism (VTE) represents one of the most common and potentially devastating complications of urologic surgery. With VTE’s rapid onset of symptoms, association with a precipitous clinical course, and high mortality rate, all urologists should be well versed in appropriate prophylaxis, prompt diagnosis, and expeditious treatment. A MEDLINE® search was performed for articles that examined the incidence, diagnosis, and treatment of VTE in urologic surgery. Additional articles were reviewed based on cited references. There is a paucity of prospective studies on VTE in the urologic literature with most recommendations for urologic surgery patients being extrapolated from other surgical disciplines. Retrospective studies place VTE incidence rates in major urologic surgeries among the highest reported—highlighting the importance of thromboprophylaxis. Conversely, VTE was rarely reported in association with endoscopic and laparoscopic procedures making mechanical thromboprophylaxis sufficient. Recent literature reveals delayed VTE occurring after hospital discharge to be a persistent threat despite inpatient preoperative prophylaxis. Computed tomographic angiography has emerged as the test of choice for diagnosing pulmonary embolism, whereas lower extremity duplex sonography is recommended for diagnosing deep venous thrombosis. Traditional angiography is rarely used. Treatment of VTE involves therapeutic anticoagulation for various lengths of time based on presence and reversibility of patient risk factors as well as number of events. Perioperative thromboprophylaxis should be considered in all major urologic surgeries. Urologists should be familiar with incidence rates, recommended prophylaxis, appropriate diagnosis, and treatment recommendations for VTE to minimize morbidity and mortality. The limited number of prospective, randomized, controlled trials evaluating the use of thromboprophylaxis in urologic surgery demonstrates the need for further research.
