Participating site overheads were not measured, a "conservatively high" estimate of these was taken to double the cost of the Rx to $374.

Costs of the health visitor also included time spent recording data collection for the study.

Medicare Medical Claims

Cardiovascular related emergency room visits and hospitalisations

Comments

Expenditure was calculated from differences in % utilisation of hospital services. i.e. Hospital charges for participants were on average 49% lower and the average annual expenditure was $6500.

* There was a calculated saving of a hospital charge of $3200, the ratio of payments to charges was 0.56 therefore $1800 actual saving. 

There was a difference in the drug usage at baseline which is not accounted for in these figures although this would make minimal impact to the results. The intervention group were more costly for drugs, procedures and service use.

Claims quoted are per member per month.

*Expenditure/pt/month enrolled

 

Overall costs were increased by 11% when the care coordination fees were taken into account.
