Meta-analysis of the Effect of Colchicine on Mortality and Mechanical Ventilation in COVID-19

Abstract: 170 The American Journal of Cardiology (www.ajconline.org) time frame analysis showed a significant drop in hospitalization rates just after PC encounters, and continued to decrease over time (Panel A). The annual trends for 90-day all-cause hospitalization rates before PC encounters showed a significant reduction over time (59.7% in 2010 to 53.3% in 2018, p <0.001), but hospitalization rates after PC remained stable over the study period (Panel B). In this observational nationwide analysis of over 25,000 acute on chronic HF admissions, PC encounters were associated with a significant reduction in all-cause, HF-specific, and non-HF 90-day hospitalization rates. This reduction was noted immediately after discharge from the index admission with a PC encounter. Hospitalization rates before PC utilization decreased over the study period perhaps due to the early recognition of value of PC among these sick patients. This study is limited by the nature of this administrative database which carries a risk of mis- or under-coding. Additionally, we could not identify patients who died after hospital discharge. Some of the reduction in readmission may be due to this factor. However, it is unlikely that death would account for the entire decrease in admission rates after a hospital PC consultation, since not all patients seen by PC physicians are appropriate for hospice or accept a palliative approach to care, and the previously reported post-HF discharge 30-day mortality rate »7% (1). Moreover, the philosophical change of care to a palliative approach encourages a decrease in low-value health care utilization such as repeat hospital admissions at the end of life. In summary, we found that patients who received a PC encounter during a hospitalization had a reduction in subsequent readmission rates. Further studies should assess the competing risk of death in this population. Disclosure: The authors have nothing to disclose, and no relationship with industry.
