Background: Use of inpatient palliative care (IPC) in the treatment of advanced cancer represents a well-established guideline recommendation. A recent analysis showed that patients with genitourinary cancer benefit from IPC at the second lowest rate among 4 examined primary cancers, namely lung, breast, colorectal, and genitourinary. Based on this observation, temporal trends and predictors of IPC use were examined in patients with metastatic urothelial carcinoma of the bladder (mUCB) receiving critical care therapies (CCTs). Patients and Methods: Patients with mUCB receiving CCTs were identified within the Nationwide Inpatient Sample database (2004–2015). IPC use rates were evaluated in estimated annual percentage change (EAPC) analyses. Multivariable logistic regression models with adjustment for clustering at the hospital level were used. Results: Of 1,944 patients with mUCB receiving CCTs, 191 (9.8%) received IPC. From 2004 through 2015, IPC use increased from 0.7% to 25.0%, respectively (EAPC, +23.9%; P<.001). In analyses stratified according to regions, the highest increase in IPC use was recorded in the Northeast (EAPC, +44.0%), followed by the West (EAPC, +26.8%), South (EAPC, +22.9%), and Midwest (EAPC, +15.5%). Moreover, the lowest rate of IPC adoption in 2015 was recorded in the Midwest (14.3%). In multivariable logistic regression models, teaching status (odds ratio [OR], 1.97; P<.001), more recent diagnosis (2010–2015; OR, 3.89; P<.001), and presence of liver metastases (OR, 1.77; P=.02) were associated with higher IPC rates. Conversely, Hispanic race (OR, 0.42; P=.03) and being hospitalized in the Northeast (OR, 0.36; P=.01) were associated with lower rate of IPC adoption. Finally, patients with a primary admission diagnosis that consisted of infection (OR, 2.05; P=.002), cardiovascular disorders (OR, 2.10; P=.03), or pulmonary disorders (OR, 2.81; P=.005) were more likely to receive IPC. Conclusions: The rate of IPC use in patients with mUCB receiving CCTs sharply increased between 2004 and 2015. The presence of liver metastases, infections, or cardiopulmonary disorders as admission diagnoses represented independent predictors of higher IPC use. Conversely, Hispanic race, nonteaching hospital status, and hospitalization in the Midwest were identified as independent predictors of lower IPC use and represent targets for efforts to improve IPC delivery in patients with mUCB receiving CCT.

Background: The distribution of metastatic sites in upper tract urothelial carcinoma (UTUC) is not well-known. Consequently, the effects of sex and age on the location of metastases is also unknown. This study sought to investigate age- and sex-related differences in the distribution of metastases in patients with UTUC. Materials and Methods: Within the Nationwide Inpatient Sample database (2000–2015), we identified 1,340 patients with metastatic UTUC. Sites of metastasis were assessed according to age (≤63, 64–72, 73–79, and ≥80 years) and sex. Comparison was performed with trend and chi-square tests. Results: Of 1,340 patients with metastatic UTUC, 790 (59.0%) were men (median age, 71 years) and 550 (41.0%) were women (median age, 74 years). The lung was the most common site of metastases in men and women (28.2% and 26.4%, respectively), followed by bone in men (22.3% vs 18.0% of women) and liver in women (24.4% vs 20.5% of men). Increasing age was associated with decreasing rates of brain metastasis in men (from 6.5% to 2.9%; P=.03) and women (from 5.9% to 0.7%; P=.01). Moreover, increasing age in women, but not in men, was associated with decreasing rates of lung (from 33.3% to 24.3%; P=.02), lymph node (from 28.9% to 15.8%; P=.01), and bone metastases (from 22.2% to 10.5%; P=.02). Finally, rates of metastases in multiple organs did not vary with age or sex (65.2% in men vs 66.5% in women). Conclusions: Lung, bone, and liver metastases are the most common metastatic sites in both sexes. However, the distribution of metastases varies according to sex and age. These observations apply to everyday clinical practice and may be used, for example, to advocate for universal bone imaging in patients with UTUC. Moreover, our findings may also be used for design considerations of randomized trials.
