Hospitalisations were reduced by 84% in the medium primary care group and 86% in the high primary care group for renal disease; 78% and 80% respectively for diabetes; and 73% to 78% for hypertension. The reductions in hospitalisations for ischaemic heart disease and chronic obstructive pulmonary disease were the lowest among the five conditions, but still statistically significant, ranging from 61% to 75% and 62% to 71%, respectively. Death rates in the high and medium primary care groups were lower than in the control group for all conditions.
