The pandora project: cost of hypertension from a general practitioner database.

Author information

  • 1PBE Consulting, Verona, Italy.



The Pandora Project is a longitudinal database--implemented by general practitioners since June 1997 in the Ravenna area (Italy)--providing information on patients with hypertension. Data from 1,651 patients were followed up for I year in order to investigate the cost of hypertension. Only direct medical costs were considered in the perspective of the National Healthcare System.


At enrollment, 552 patients were classified as normotensive, 1,099 as hypertensive. After 1 year, among normotensive group, 352 patients remained normotensive and 200 became hypertensive; among hypertensive group, 323 patients became normotensive and 776 remained hypertensive. The average total cost per patient at follow-up was 779.59 Euros. About 46% of total cost was due to anti-hypertensive therapy, irrespective of the evolution of blood pressure levels registered, whilst other direct costs represented 54% of total patient cost in all cohorts. It is possible that co-morbidities play a significant role in this situation. Patient aged 80-89 years generate higher costs. Even if further investigation is needed on the burden of comorbidity on a per-patient cost of hypertension, this work provides evidence that the average total cost per patient is likely to increase with age and co-morbidities. Key words: cost-of-illness, costs, economics, hypertension.
