Proportional subdistribution hazards (PSH) model is a commonly used method for regression analysis of time-to-event data in the presence of competing risks. Association of LODDS, LNR, and pN stage with OS and CSS were explored using Cox proportional hazard model and Cox competing risk model, respectively, with results showing as hazard ratio (HR) and 95% confidence interval (CI). (See the Lecture Notes for a discussion of how this model may be generalized to allow for correlated risks.) Latouche et al. 2022;327(6):583. https://doi.org/10.1001/jama.2021.24868. Using data available as of 7 February 2022, we examined the length of stay distributions of hospitalised COVID-19 cases in NSW in two periods: the Delta only epidemic (1 July 202114 December 2021) and the mixed Omicron and Delta epidemic (15 December 20217 February 2022) to estimate the reduction in hospital length of stay during these periods.

Elbe S, Buckland-Merrett G. Data, disease and diplomacy: GISAIDs innovative contribution to global health. We considered each branching step in the clinical pathway model as a set of competing risks in a multi-state survival model to account for this censoring. The pitfall is that cumulative incidence may not depend on a covariate in the same way, i.e. DJ and GS had roles in data collection and processing. Conversely, the probability of admission to ICU from ward is substantially lower for all age groups in the Omicron-Delta and Omicron periods, compared to the Delta period.

The reduced length of stay estimates we have produced are consistent with reports of Omicron-dominated epidemics in other settings internationally, for example: An analysis of a private hospital network in South Africa across 2351 Omicron patients and 6,342 Delta patients showed a reduction in median total length of stay from approximately 78 days in the Delta epidemic wave to 3 days in the Omicron epidemic [19]; an analysis of patients within a Houston healthcare network showed a reduction in median total length of stay from 5.4 days for Delta patients to 3.0 days for Omicron patients [20], and; an analysis of a Portuguese cohort reported a 4 day reduction in the mean length of hospital stay between Delta and Omicron [21].

Recent decades have witnessed many applications of survival analysis in various disciplines. The distributions of lengths of stay were modelled as gamma distributions across all transitions, with shape and rate parameters varying by age group in the ward compartment, but with only the shape parameter varying by age group in the ICU and post-ICU-ward compartments (due to limited sample size). J Infect. Solid lines represent observed data via Aalen-Johansen non-parametric estimates.
