How and where patients with advanced cancer facing limited survival spend their time is critical. Healthcare contact days (days with healthcare contact outside the home) offer a patient-centered and ...practical measure of how much of a person's life is consumed by healthcare. We retrospectively analyzed contact days among decedent veterans with stage IV gastrointestinal cancer at the Minneapolis Veterans Affairs Healthcare System from 2010 to 2021. Among 468 decedents, the median overall survival was 4 months. Patients spent 1 in 3 days with healthcare contact. Over the course of illness, the percentage of contact days followed a "U-shaped" pattern, with an initial post-diagnosis peak, a lower middle trough, and an eventual rise as patients neared the end-of-life. Contact days varied by clinical factors and by sociodemographics. These data have important implications for improving care delivery, such as through care coordination and communicating expected burdens to and supporting patients and care partners.
Situs inversus viscerum (SIV) is a congenital condition defined by left-to-right transposition of all visceral organs. This anatomical variant has caused technical challenges in endoscopic retrograde ...cholangiopancreatography (ERCP). Data on ERCP in patients with SIV are limited to case reports of unknown clinical and technical success rates. This study aimed to evaluate the clinical and technical success rates of ERCP in patients with SIV.
Data from patients with SIV who underwent ERCP were retrospectively reviewed. The data were collected by querying the nationwide Veterans Affairs Health System database for patients diagnosed with SIV who underwent ERCP. Patient demographics and procedural characteristics were collected.
Eight patients with SIV who underwent ERCP were included. Choledocholithiasis was the most common indication for ERCP (62.5%). The technical success rate was 63%. Subsequent ERCP with interventional radiology-assisted rendezvous has increased the technical success rate to 100%. Clinical success was achieved in 63% of cases. Among cases of subsequent rendezvous ERCP after conventional ERCP failure, clinical success was achieved in 100%.
The clinical and technical success rates of ERCP in patients with SIV were both 63%. In patients with SIV in whom ERCP fails, interventional radiology-assisted rendezvous ERCP can be considered.
ObjectivesPrior studies suggest that patients with age-related macular degeneration (AMD) have poorer COVID-19 outcomes. This study aims to evaluate whether AMD is associated with adverse COVID-19 ...outcomes in a large clinical database.DesignCase–control study.SettingWe obtained demographic and clinical data from a national US Veterans Affairs (VA) database for all Veterans aged 50 years or older with positive COVID-19 testing prior to 2 May 2021.Primary and secondary outcome measuresThe primary outcome measure was hospitalisation. Secondary outcome measures were intensive care unit admission, mechanical ventilation and death. Potential associations between AMD and outcome measures occurring within 60 days of COVID-19 diagnosis were evaluated using multiple logistic regression analyses.ResultsOf the 171 325 patients in the study cohort, 7913 (5%) had AMD and 2152 (1%) had severe AMD, defined as advanced atrophic or exudative AMD disease coding. Multiple logistic regression adjusting for age, Charlson Comorbidity Index, sex, race, ethnicity and COVID-19 timing showed that an AMD diagnosis did not significantly increase the odds of hospitalisation (p=0.11). Using a Bonferroni-adjusted significance level of 0.006, AMD and severe AMD also were not significant predictors for the secondary outcomes, except for AMD being modestly protective for death (p=0.002).ConclusionsAfter adjusting for other variables, neither AMD nor severe AMD was a risk factor for adverse COVID-19 outcomes in the VA healthcare system. These findings indicate that an AMD diagnosis alone should not alter recommended ophthalmic management based on COVID-19 adverse outcome risk.
Objective: New regimens to treat hepatitis C virus infection have expanded the eligible patient population to include more patients receiving concurrent warfarin. The primary objective of this study ...was to assess whether a drug interaction occurs when these regimens are added to warfarin therapy. Methods: This was a retrospective cohort design using a nationwide database of the Veterans Affairs Health System. Patients on warfarin therapy treated with sofosbuvir or ombitasvir, paritaprevir-ritonavir, and dasabuvir (OBV-PTV/r-DSV) from March 2014 through October 2015 were identified. The warfarin dose response was calculated using a warfarin sensitivity index (WSI) defined as the steady-state INR divided by the mean daily warfarin dose. The primary outcome was the change in WSI from hepatitis C treatment initiation to completion. Results: The final sample consisted of 271 patients. The WSI decreased 23% from a mean baseline value of 0.53 to 0.39 (decrease of 0.14; 95% CI = 0.11 to 0.16; P < 0.001). OBV-PTV/r-DSV produced a significantly greater decrease than any sofosbuvir regimen. Concurrent ribavirin accounted for an additional decrease in warfarin sensitivity of −0.09 (95% CI = −0.06 to −0.12; P < 0.001). The percentage of subtherapeutic INR results increased from 26% prior to hepatitis C treatment to 58% during treatment. Conclusions: Results indicate a clinically significant reduction in warfarin dose-response when hepatitis C treatment regimens were added to warfarin. They were most profound with OBV-PTV/r-DSV. Ribavirin was associated with an additive effect. Clinicians should be aware of this potential drug interaction to closely monitor and minimize subtherapeutic levels of anticoagulation.
