Hypothesis
To validate and update a prediction rule for estimating the risk of leprosy-related nerve function impairment (NFI).
Conclusion
The adjusted prediction rule can better identify patients at risk of developing nerve function impairment in leprosy.
Supporting Evidence
- NFI occurred in 115 of 864 patients (13%).
- The adjusted prediction rule identified 80% of patients with NFI compared to 72% with the original rule.
- The c statistic for the adjusted prediction rule improved from 0.79 to 0.81.
Takeaway
Doctors can use a new method to find out which leprosy patients are likely to have nerve problems, helping them get treatment sooner.
Methodology
A prospective cohort study analyzed data from newly diagnosed leprosy patients to validate and adjust a prediction rule for nerve function impairment.
Limitations
The study could not validate the adjusted prediction rule on the original Bands cohort due to lack of serology data.
Participant Demographics
The study included 864 leprosy patients (538 males, 326 females; median age 34 years, range 5–84 years).
