Figure S3: Cumulative survival probabilities of individuals by each pathway, across different epidemic periods and age groups. In your setting with 3 competing events, the cumulative incidence of cause 1 can be defined as$\ F_1 (t)= _0^t[S(x)h_1 (x)dx] $, where$\ h_1 $ is the causes-specific hazard for cause 1 and $\ S $ is the overall survivor function. Analysis of the deidentified secondary dataset was performed under the guidelines and regulations of the dataset owner (NSW Ministry of Health). I don't think you can circumnavigate these problems with alternative methodological solutions, since they stem from fundamental limitations in survival analysis. Can state or city police officers enforce the FCC regulations? 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.

By default, subjects with a competing risk are treated as censored, which representing transfer between different wards), episodes were concatenated to produce a single stay, where an individual would be assumed to be in hospital from the time of their earliest episodes admission until the time of their latest episodes discharge.

If data on treatments at the individual-level were available, this could be included as an additional stratification alongside age-group and epidemic period, allowing for the effect of treatments at the population-level to be monitored in real-time. Why does secondary surveillance radar use a different antenna design than primary radar? In some settings, both types of regression models should be estimated for each of the competing risks to permit a full understanding of the effect of covariates on Figure S1: Mixed Omicron-Delta epidemic period length of stay parameter samples, demonstrating the correlation between log(shape) and log(scale).

This competing-risk approach produces time-to-event and transition probability results that are more straightforward to interpret and to utilise in further modelling work in comparison to the more typical cause-specific hazards approach to analysing multi-state survival data [12, 14]. <>

Classical survival analysis models in competing risks of multiple non-recurrent single events are possible to generalize to multiple recurrent events. Competing risks analysis considers time-to-first-event (survival time) and the event type (cause), possibly subject to right-censoring.

Is it possible to compare survival curves from different models (Cox and Fine-Gray)? The difference is that the new risk set includes subjects who have experienced a competing event before \(X_i\) and are therefore immortal. To learn more, see our tips on writing great answers. To evaluate the performance of the real-time estimation process, we performed two additional analyses: (1) retrospective length of stay estimates were produced using a later data extract (29 August 2022 compared to 7 February 2022), by which time all individuals admitted during the mixed Omicron-Delta and Omicron HNE epidemic periods had complete observations and (2) naive length of stay estimates were produced using data as at 7 February, removing any individuals with censored observations.
