Calculation for weights by CRG core health status from model 2012

Core health status	Ln (C + 1) (a)	Expenditure C (b)	Standard weight (c)
1. Healthy	1.736	8.607	1
2. History of significant acute disease	3.552	58.068	6.75
3. Single minor chronic disease	4.176	109.242	12.69
4. Minor chronic disease in multiple organ systems	5.427	384.212	44.64
5. Single dominant or moderate chronic disease	5.535	427.851	49.71
6. Chronic disease in 2 or more Organ Systems	6.728	1413.267	164.21
7. Dominant Chronic Disease in 3 or more Organ Systems	7.496	3048.575	354.21
8. Dominant and Metastasic Malignances	6.606	1250.432	145.29
9. Catastrophic conditions	6.229	858.032	99.69

(a) = Ln (C + 1).

(b) = (1.693 e^a)-1.

(c) = b_i/b₁.
