case_images: Further case-mix profiles are seen in Figure 3. There is clear evidence that the mean Charlson index (Figure 3, top row) in RSH has seen a step increase and that at PRH it has been steadily declining with a clear dip in year 3. However the length of stay profiles (Figure 3, middle row) at RSH and PRH do not fit with this view.
