Real-time estimation of length of stay is challenging and the uncertainty resulting from the censoring of outcomes means that any real-time estimates will be imperfect. BMC Infectious Diseases Competing risks arise in studies when subjects are exposed to more than one cause of failure and failure due to one cause excludes failure due to other causes.

Casirivimab-imdevimab treatment is associated with reduced rates of hospitalization among high-risk patients with mild to moderate coronavirus disease-19.

INTRODUCTION. Bias by censoring for competing events in survival analysis In survival analysis, competing events preclude the occurrence of the event of interest. Article This is not the case when considering the cumulative incidence (which gives you the probability of occurrence of that cause, another quantity of interest). In Kaplan-Meier estimation, an individual is removed from the risk set when the individual experiences competing event, i.e. The real-time estimated mean lengths of stay for the Omicron-Delta epidemic period were estimated accurately (i.e., compared to the retrospective estimates), with only slight differences. Where an individual had been admitted to the intensive care unit (ICU), the initial and final known date and time were available in the data, alongside a total duration within ICU (which excluded any periods of ward stay between these initial and final known dates, and may be indicative of readmission to ICU). This solves the issue above, but makes results rather tricky to interpret (or introduces other limitations, as the one you reported). For each of these analyses, distribution fits were produced with the fitdistrplus R package [16]. Multivariable analysis were conducted by Cox regression models, and variables with P < 0.05 in Univariables analysis were eligible for the Cox regression models, and the independent risk factors in multivariate analysis were futher used to conduct subgroup analyses. 2020;22(2):98102. At this stage, individuals were excluded from analysis where any two of their consecutive episodes were separated by at least 48 hours outside of the hospital system (n = 619, 1442 and 85 for Delta, mixed Omicron-Delta and HNE Omicron epidemic periods respectively; Fig.2). There are other characteristics to be taken into account such as age, gender, etc. As with Cox models, Fine and Gray is also based on proportional hazards. It is therefore possible that the length of stay estimates for the mixed Omicron-Delta and Omicron Hunter New England epidemic periods are influenced by the inclusion of a small number of BA.2 lineage cases. Peralta-Santos A, Rodrigues EF, Moreno J, Ricoca V, Casaca P, Fernandes E, Gomes JP, Ferreira R, Isidro J, Pinto M, Borges V, Vieira L, Duarte S, Sousa C, Almeida JP, Menezes L, Ferreira BI, Matias, A, Pelerito A, Freire S, Grilo T, Borges CM, Moutinho V, Leite A, Kislaya I, Rodrigues AP, Leite PP, Nunes B. Omicron (BA.1) SARS-CoV-2 variant is associated with reduced risk of hospitalization and length of stay compared with delta (b.1.617.2). However, casirivimab-imdevimab has been noted to have substantially lower efficacy against the Omicron variant [32], and the use of tocilizumab was likely limited at the time due to supply constraints [33]. xV[oX~G?]_RJ.v@ZE'D"fPcC1!373| t;8)'9aw;&_0[C$,gs+Y=v~vz (((+m 4dVKCB*&,I=a @OAY` The alternative Grays test is a non-parametric test that does not rely on the proportional hazards assumption; however, it does not offer an effect size or the ability to adjust for confounders, analogous to the log-rank test. A Proportional Hazards Model for the Subdistribution of a Competing Risk. endobj Because competing risks are present, it is no longer appropriate to interpret the cause-specific hazard ratios in terms of a relative risk type of measure as regular hazard ratios. Track Life University . I guess my take was rather that either of the approaches is problematic in one way or another (cause-specific assumes independency and Fine-Gray does not have an in-built restriction to not dye more than once or from more than one cause and the overall prob may be >1). Estimates from the Hunter New England Omicron dataset are not displayed where sample size was insufficient to produce a model fit, Cumulative survival probabilities of individuals in the ward-to-discharge, ward-to-ICU and ICU-to-post-ICU pathways, across epidemic periods and age groups.
