Hypothesis

The study aims to derive a weighted capitation model to account for demographic differences among general practices in Italy.

Conclusion

The ASSET model provides a useful framework for understanding and allocating prescribing resources, but it cannot fully explain the variations in individual prescribing costs.

Supporting Evidence

  • Subjects over 65 years of age accounted for 56% of total prescribing costs.
  • The ASSET model estimated 94% of total 2005 Italian prescribing costs.
  • On average, costs for a 75-year-old subject would be 12 times the costs for a 25–34 year-old subject if male.

Takeaway

This study looks at how much medicine people in Italy need based on their age and gender, helping to make sure everyone gets the right amount of medicine.

Methodology

Data on individual prescription costs and demographics were collected from three Regional Health Authorities over a 12-month period.

Potential Biases

Idiosyncratic prescribing by general practitioners may lead to unfair distribution of resources.

Limitations

The ASSET model only explains about 25% of the variation in prescribing costs among individuals.

Participant Demographics

The sample included 3,175,691 Italian subjects with a distribution across various age and sex groups.
