Introduction: The survivorship of peripheral intravenous catheters (PIVCs) placed in hospitalized patients is shockingly poor and leads to frequent reinsertions. We aimed to evaluate differences in failure rates and IV insertion practices for PIVCs that are placed in the emergency department (ED) compared to those placed in the inpatient (IP) setting. Methods: We conducted a retrospective electronic medical record review of PIVC survival at a single-site suburban, academic tertiary care referral center with 130,000 annual ED visits and 1100 inpatient beds. Adult patients admitted requiring at least one PIVC were included. The primary outcome was incidence of premature failure of PIVCs. Secondary outcomes included dwell time, completion of therapy, catheter diameter, and site of insertion as they relate to PIVC survival. Results: Between January 2018 and July 2019, 90,743 IV catheters were included from 47,272 unique patient encounters in which 35,798 and 54,945 catheters were placed in the ED and IP units, respectively. There was no significant difference in failure rate between the ED and IP PIVCs, with 53.1% of ED PIVCs failing and 53.4% of IP PIVCs failing ( p = 0.35). Mean dwell time for ED PIVCs was 3.4 days compared to a mean of 3.2 days for IP placed PIVCs ( p < 0.001). 48% of ED PIVCs achieved completion of therapy at the first insertion compared to 59% of IP PIVCs ( p < 0.001). The antecubital fossa and forearm had the lowest failure rate of 53% and 50%, respectively, and 22 gauge PIVCs had the highest failure rate of 60.5%. Conclusion: PIVCs have similar poor survival rates regardless of ED versus IP location of the insertion. The forearm and antecubital fossa sites should be preferentially used. Smaller diameter (22G) catheters have highest complications and poorest survival regardless of site of insertion. Larger diameter catheters (18 or 20 gauge) may offer improved outcomes.
IMPORTANCEThe monoclonal antibody combination of casirivimab and imdevimab reduced viral load, hospitalization, or death when administered as a 1200-mg or greater intravenous (IV) dose in a phase 3 COVID-19 outpatient study. Subcutaneous (SC) and/or lower IV doses should increase accessibility and/or drug supplies for patients. OBJECTIVE To assess the virologic efficacy of casirivimab and imdevimab across different IV and SC doses compared with placebo. DESIGN, SETTING, AND PARTICIPANTS This phase 2, randomized, double-blind, placebocontrolled, parallel-group, dose-ranging study included outpatients with SARS-CoV-2 infection at 47 sites across the United States. Participants could be symptomatic or asymptomatic; symptomatic patients with risk factors for severe COVID-19 were excluded. Data were collected from December 15, 2020, to March 4, 2021. INTERVENTIONS Patients were randomized to a single IV dose (523 patients) of casirivimab and imdevimab at 300, 600, 1200, or 2400 mg or placebo; or a single SC dose (292 patients) of casirivimab and imdevimab at 600 or 1200 mg or placebo. MAIN OUTCOMES AND MEASURES The primary end point was the time-weighted average daily change from baseline (TWACB) in viral load from day 1 (baseline) through day 7 in patients seronegative for SARS-CoV-2 at baseline. RESULTS Among 815 randomized participants, 507 (282 randomized to IV treatment, 148 randomized to SC treatment, and 77 randomized to placebo) were seronegative at baseline and included in the primary efficacy analysis. Participants randomized to IV had a mean (SD) age of 34.6 (9.6) years (160 [44.6%] men; 14 [3.9%] Black; 121 [33.7%] Hispanic or Latino; 309 [86.1%] White); those randomized to SC had a mean age of 34.1 (10.0) years (102 [45.3%] men; 75 [34.7%] Hispanicor Latino; 6 [2.7%] Black; 190 [84.4%] White). All casirivimab and imdevimab treatments showed significant virologic reduction through day 7. Least-squares mean differences in TWACB viral load for casirivimab and imdevimab vs placebo ranged from -0.56 (95% CI; -0.89 to -0.24) log 10 copies/mL for the 1200-mg IV dose to -0.71 (95% CI, -1.05 to -0.38) log 10 copies/mL for the 2400-mg IV dose. There were no adverse safety signals or dose-related safety findings, grade 2 or greater infusionrelated or hypersensitivity reactions, grade 3 or greater injection-site reactions, or fatalities. Two serious adverse events not related to COVID-19 or the study drug were reported.
Background Well-differentiated thyroid cancer has better outcomes compared to undifferentiated/anaplastic thyroid cancer. The incidence of well-differentiated thyroid cancer is known to be more in women whereas it is approximately the same in both genders for anaplastic thyroid cancer. The variability of incidence-based mortality across gender in the context of race has not been studied. This study analyzes the rates of incidence-based mortality from the years 2000 to 2016 amongst both the genders in four racial groups. Methods The Surveillance, Epidemiology, and End Results (SEER) database was utilized to conduct a nation-wide analysis for the years 2000 to 2016. Incidence-based mortality for all stages of well-differentiated and undifferentiated thyroid cancer was queried and the results were grouped by race (Caucasian/White, African American/Black, American Indian/Alaskan Native and Asian/Pacific Islander) and gender. All stages and ages were included in the analysis. Two sample t -test was used to determine statistically significant difference between various subgroups. Results Incidence-based mortality rates (per 100,000) for well-differentiated and undifferentiated thyroid cancer for all races and both the genders were calculated. The incidence-based mortality rates for both genders are approximately the same despite a 2–3:1 difference in incidence. Anaplastic thyroid cancer has a higher mortality rate in Caucasian and Asian/Pacific Islander women compared to men despite an equal ratio in incidence. As expected, the mortality rates of anaplastic thyroid cancer were significantly higher compared to well-differentiated cancer across all races and genders. Also, Asian/Pacific Islander women have a higher rate of mortality compared to both the genders of Caucasian and African American races. Conclusion Incidence-based mortality for anaplastic thyroid cancer is higher in women in all races whereas there is no difference in mortality between men and women for well-differentiated thyroid cancer. This is divergent from the incidence ratios noted in these malignancies. In the context of increasing incidence of thyroid cancer for the past few decades, this data suggests that additional resources may be devoted to decreasing the disparity of mortality in this gender.
