competing risk models in survival analysis

I'll check the first-order Markov models that Frank Harrell suggested above, I was also thinking along the lines of a 2-step model in which first a failure by any cause is modelled, and then subject that it happened, probability that it was a specific cause A or B. I think "cure" models do something like that in simpler way, but I did not dwell into those. Such events are known as competing risk events.

Since finegray applies a Fine-Gray model to competing risk (multi-state) data, giving as result a dataset with interval censoring time and weights <1 for observations with competing events, I'm not able to understand whether the assumption made by the rpart routine are still valid for this kind of data. Circulation. Austin PC, Lee DS, Fine JP. 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). Tobin, R.J., Wood, J.G., Jayasundara, D. et al. 2020;22(2):98102. If this censoring was not appropriately considered in the analysis, estimates would be biased down by an over-representation of individuals with a shorter length of stay [11]. J Am Stat Assoc.

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. Figure 5 shows the estimated length of stay distributions compared to the non-parametric Aalen-Johansen estimates. In contrast, the nave Kaplan-Meier approach assumes that these individuals would experience the same probability of event of interest in pure theory (non-informative censoring). There seems to be two main approaches for the competing risk, cause-specific and Fine-Gray (https://onlinelibrary.wiley.com/doi/10.1002/sim.2712).

Where the recorded duration in ICU was less than that indicated by the admission and discharge dates and times (which differed in only approximately 6% of admissions), we assumed that the additional time outside the ICU contributed to the post-ICU ward stay. 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. Track Life University . \], \[ Following review, the NSW Ministry of Health determined that this study met that threshold and therefore provided approval for the study to proceed. We also considered data on the stays of individuals within the Hunter New England Local Health District, where it was reported that Omicron was the only circulating variant, and found mean ward-to-discharge length of stays of 2.05 (95% CI: 1.802.30), 2.92 (95% CI: 2.503.67) and 6.02 days (95% CI: 4.917.01) for the same age groups. in the presence of competing risk), the one-to-one relationship does not exist between the cause-specific hazard function and the corresponding CIF.
