Hospital length of stay was substantially reduced across all clinical pathways during a mixed Omicron-Delta epidemic compared to a prior Delta epidemic, contributing to a lessened health system burden despite a greatly increased infection burden. The former considers competing risk events as non-informative censoring, whereas the latter takes into account the informative censoring nature of the competing risk events [Zhang, 2017]. Nevertheless, working with cause-specific hazards allows you to obtain very punctual estimates of the impact different covariates have on your cause(s) of interest.

We estimated that the mean length of stay for patients hospitalised during the mixed Omicron and Delta epidemic period (15 December 20217 February 2022) was reduced by a factor of approximately half across most clinical pathways compared to the Delta-only period (1 July 202114 December 2021) (Fig. F_k(t) = \int_0^tS(u)h_k(u)du = \int_0^t S(u)dH_k(u), k = 1, \cdots, K f endobj Crit Care Resuscit. : Shortages of tocilizumab (Actemra) medicines.

The probabilities of admission to ward following ICU are similar across each age group, though note that these estimates are based on small numbers for the Omicron period. Note that y- and x-axis extents differ across both pathways and age groups. As we did not have access to information on each individuals vaccination status, previous SARS-CoV-2 infections, comorbidities, or treatments received, we were not able to investigate the potential effects of these factors in our analysis. Cumulative survival probability plots were produced across each pathway, comparing the parametric gamma distribution fits with non-parametric Aalen-Johansen estimates to visually assess goodness-of-fit (Additional file 1: Figs. In this setting, it would often be of interest to calculate the cumulative incidence of a specific event of Figure 6 shows the retrospective and naive estimates of the length of stay during the mixed Omicron-Delta period, compared to the real-time estimates.
