Table 3 Adjusted incidence rate ratios and cost ratios according to knowledge score among 121 patients

From: Poor disease knowledge is associated with higher healthcare service use and costs among patients with cirrhosis: an exploratory study

Data source: Queensland hospital admitted patient data collection IRR (95%CI)* p value Adjusted-IRR (95%CI)* p value
All-cause admission 0.42 (0.35–0.49) < 0.001 0.24 (0.20–0.29) < 0.001
Cirrhosis admission 1.21 (0.82–1.79) 0.338 0.59 (0.35–0.99) 0.046
Planned one-day admission (cirrhosis admission) 4.59 (1.79–11.73) 0.001 3.96 (1.46–10.74) 0.007
Admitted via the emergency department (any admission) 0.70 (0.51–0.97) 0.034 0.51 (0.35–0.76) 0.001
Admitted via the emergency department (cirrhosis admission) 0.90 (0.57–1.41) 0.646 0.57 (0.32–1.00) 0.050
Data source: emergency data collection IRR (95%CI)* p value IRR (95%CI)* p value
Emergency presentation (any reason) 0.76 (0.58–1.00) 0.048 0.62 (0.44–0.85) 0.004
Cirrhosis-related emergency presentation 0.70 (0.40–1.25) 0.229 0.34 (0.16–0.72) 0.005
Data source: National hospital cost data collection Cost ratio (95%CI)** p value Cost ratio (95%CI)** p value
Total cost for any admission 0.25 (0.24–0.25) < 0.001 0.09 (0.08–0.09) < 0.001
Total cost for cirrhosis admissions 0.54 (0.53–0.54) < 0.001 0.30 (0.29–0.30) < 0.001
  1. Bold values indicates statistically significant (p < 0.05)
  2. Incidence rate ratio (IRR) and cost ratio with poor knowledge as reference group
  3. Two patients for whom we did not have hospital admission data were excluded from these analyses
  4. *Multivariable Poisson regression model included education level, socioeconomic status, presence of complications of cirrhosis and duration of cirrhosis
  5. **Multivariable Poisson regression model included education level, Charlson Comorbidity Index, and presence of complications of cirrhosis
