Rationale & Data Sources

This dashboard uses parameter values updated to reflect current real-world data for the ≥75 population in the HSE Mid-West (University Hospital Limerick region).

Parameter                 | Suggested Value | Rationale / Source
------------------------- | --------------- | ------------------------------------------------------------
Population ≥75            | ~30,000         | Census 2022 shows ~33,600 (65+) in Limerick alone; Midwest region (Clare, Limerick, N. Tipperary) likely has even more. (CSO, HSE.ie, Nenagh Guardian)
Annual net growth rate    | 5%              | Implemented as raw growth 10% minus mortality 5% (net +5%/yr).
Mortality/discharge rate  | 5% (3–10%)      | Typical annual attrition for ≥75 cohort; allows flexibility in modeling.
ED attendance rate        | 900 / 1,000/yr  | Nationally, ~15% of ED attendances are ≥75; Midwest likely higher than 600/1,000. (HSE, IHCA)
Admission rate from ED    | 55%             | National data show ~52% admitted; 55% used as realistic midpoint.
Mean Length of Stay (LOS) | 6.5 days        | National ALOS for emergency inpatients ~6.3 days pre-pandemic.
Unit cost per admission   | €5,800          | Approx. per diem €834 × 7 days.
