  1. aThe cut point for acute level LOS was ≤5.8 days. Women with a maximum LOS of ≤5.8 days in their last year of life were compared with women who add no hospitalisations. A total of 223 (56.3 %) of this sample experienced an acute level LOS
  2. bHosmer-Lemeshow goodness of fit p value for the original model was 0.78 and 0.48 for the final model
  3. cThe cut points for a medium level LOS was >5.8 days and ≤11.9 days. Women with a maximum LOS was >5.8 days and ≤11.9 days in their last year of life were compared with women included in the acute level LOS analysis (i.e. those who had a maximum stay of ≤5.8 days (acute) or no hospitalisation). A total of 248 (38.5 %) of women of this sample experienced a medium level LOS
  4. dHosmer-Lemeshow goodness of fit p value for the original model was 0.14 and 0.51 for the final model
  5. eThe cut point for a palliative level LOS was >11.9 days. Women with a maximum LOS in their final year of life of >11.9 days were compared with women included in the medium LOS analysis (i.e. those who had a maximum LOS of >5.8 days and ≤11.9 days (medium), >0 and ≤5.8 days (acute) and no hospitalisation). A total of 561 (46.6 %) of women of this sample experienced a palliative level LOS
  6. fHosmer-Lemshow goodness of fit p value for the original model was 0.08 and 0.07 for the final model
  7. gNo is the reference category
  8. hOnly included in the medium and palliative LOS models
  9. iOnly included in the palliative LOS model
