Table 3 Significant risk factors for time to death or hospital admission during 16-month study period

From: Risk of death or hospital admission among community-dwelling older adults living with dementia in Australia

Variables during three months before commencement Wald HR 95% CI of HR p
Hospital admissions 10.92 2.93 1.55–5.53 0.001
GDS score 4.84 0.65 0.45–0.96 0.028
ADL score 2.79 0.99 0.98–1.00 0.095
IADL score 1.96 1.16 0.94–1.44 0.162
Carer stress score 2.33 1.02 0.99–1.05 0.127
Carer relationships     
 Relatives/friends     
 Partner/spouse 0.24 0.75 0.23–2.45 0.628
 Son/daughter/in-law 0.04 1.13 0.35–3.60 0.838
BPSD frequency score 0.00 1.00 0.97–1.02 0.992
  1. Notes:
  2. 1. All variables were measured at baseline; commencement means being enrolled and commencing using services provided by EACHD program.
  3. 2. Having hospital admissions during the past three months = 1; having no admissions = 0. GDS score: 1–7; higher score, better cognitive status. ADL score: 0–100 (full score); higher score, better functional status. IADL score: 0–14 (full score); higher score, better instrumental functional status. BPSD frequency score: 0–228 (full score: 6*38); higher score, more frequent BPSD. Carer stress score: 0–152 (full score: 4*38); higher score, higher care stress level.
  4. 3. HR (hazard ratio) > 1 indicates increased risk of the occurrence of an event; HR < 1 means decreased risk of the occurrence of an event.
  5. 4. -2 Log Likelihoods in the final model and null model were respectively 374.235 and 379.595.
