Hypothesis
Can the Oral Health Impact Profile (OHIP) be mapped to the EuroQol to estimate health state values?
Conclusion
Health state values can be derived from OHIP-14 scores for populations where utility has not or cannot be measured directly.
Supporting Evidence
- The OHIP item 'painful aching in mouth' was significantly related to health state values.
- Mean forecast errors were lower for the continuous model compared to the categorical model.
- Data were collected from 375 patients with a response rate of 72%.
Takeaway
This study helps us understand how to turn oral health surveys into useful health scores, which can help in health studies and cost analyses.
Methodology
Data were collected from a random sample of patients treated by South Australian dentists using mailed self-complete questionnaires.
Potential Biases
Potential bias due to self-selection of patients and dentists participating in the study.
Limitations
The study may overestimate health states as it was conducted on dental patients who may have more oral disease than the general population.
Participant Demographics
Majority of patients were female (59.5%), born in Australia (75.5%), and had dental insurance (64.8%).
