The relationship between physician cost and functional status in the elderly
1Department of General Practice, University of Sydney, Australia.
Summary
Functional status impacts healthcare costs in the elderly. Better physical and emotional health scores correlated with lower specialist costs, while GP costs were influenced by age and gender.
Area of Science:
- Gerontology
- Health Economics
- Medical Sociology
Background:
- Understanding healthcare expenditure drivers in aging populations is crucial.
- Functional status is a key determinant of health outcomes and resource utilization in older adults.
Purpose of the Study:
- To investigate the association between functional status and healthcare costs incurred by general practitioners and specialists in elderly individuals.
- To develop predictive cost models incorporating functional status measures.
Main Methods:
- A longitudinal study of 328 patients aged 65+ admitted to a Sydney hospital.
- Multiple linear regression analyses were used to develop two predictive cost models.
- The Short Form 36 (SF-36) health survey was utilized to assess functional status.
Main Results:
- For general practitioner costs, female gender and older age were positively associated, while post-discharge service mentions and higher SF-36 vitality/role emotional scores were negatively predictive.
- Specialist costs were positively associated with SF-36 physical functioning and mental health domains.
- Higher vitality, role emotional scores, and post-discharge service mentions were negatively associated with specialist costs.
Conclusions:
- Predictive cost models can differentiate between general practitioner and specialist costs in the elderly.
- These models can inform future physician care strategies for older adults.
- Cost modeling facilitates evidence-based decision-making in geriatric healthcare resource allocation.
