BACKGROUND:This study reports the oncological and functional outcomes in men with localized prostate cancer (Pca) who were treated with primary whole gland cryoablation (WGC) of the prostate. METHODS:The authors retrospectively reviewed their prospectively collected cryosurgery database between January 2002 and September 2019 for men who were treated with WGC of the prostate at a tertiary referral center. Primary outcome includes biochemical recurrence-free survival (BRFS). Secondary outcomes include failure-free survival (FFS), metastasis-free survival (MFS) and adverse events. RESULTS:A total of 260 men were included in the study. Men having had prior treatment for Pca were excluded. Median follow-up was 107 months (interquartile range [IQR], 68.3-132.5 months). BRFS, FFS, and MFS at 10 years were 84%, 66%, and 96%, respectively. High risk D'Amico classification was associated with a lower BRFS and FFS on multivariable analysis. No patient had any Pca-related death during follow-up. American Urological Association symptoms score and bother index were unchanged following cryoablation. Median International Index of Erectile Function score precryoablation and post-cryoablation was 7 (IQR, 3-11) and 1 (IQR, 1-5), respectively. Stress urinary incontinence, defined as requiring any protective pads only occurred in five patients (2%). No patient developed a fistula. Grade > 2 Clavien-Dindo adverse events occurred in six (2.3%) patients. CONCLUSION/CONCLUSIONS:WGC of the prostate can achieve excellent oncological and functional outcomes in men with localized Pca at the 10-year mark. Primary WGC may be a good option for men who desire to preserve urinary continence and have an excellent oncologic outcome. LAY SUMMARY/BACKGROUND:Primary whole gland cryoablation is an alternative treatment option to radical prostatectomy and radiotherapy for men with organ-confined prostate cancer. Patients had excellent cancer outcomes 1 years after whole gland cryoablation, and patients with PSA nadir 0.1 ng/ml or lower after treatment were less likely to have disease recurrence.

BACKGROUND:Accurately identifying the number of practicing hospitalists across the United States continues to be a challenge. Characterizing the workforce is important in the context of healthcare reforms and public reporting. OBJECTIVE:We sought to estimate the number of adult hospitalists practicing in the United States over an 8-year period, to examine patterns in growth, and begin to explore billing patterns. DESIGN, SETTINGS, AND PARTICIPANTS/METHODS:Retrospective study using national Medicare Part B claims datasets. We applied a commonly used 90% threshold of billing hospital visit-associated Healthcare Common Procedure Coding System codes to identify adult hospitalists in publicly available Medicare Provider Utilization and Payment data for 2012-2019. We then analyzed billing patterns for those identified hospitalists. MAIN OUTCOMES AND MEASURES/METHODS:Identify trends in the number of identified adult hospitalists, including those self-identified. Compare hospitalists' billing to that of non-hospitalist Internal Medicine and Familiy Medicine physicians. RESULTS:We saw more than a 50% growth rate of practicing adult hospitalists between 2012 and 2019. In 2019, we identified 44,037 adult hospitalists. CONCLUSIONS:The number of adult hospitalists continued to grow at a consistent rate, such that hospitalists are in the top five largest physician specialties in the United States. In the absence of more formal identification and consistent use by hospitalists, a threshold continues to be a meaningful tool to characterize the workforce.
