| description | Introduction High-impact chronic pain (HICP) significantly affects the quality of life for millions of US adults, imposing substantial economic/healthcare burdens. Disproportionate effects are observed among racial/ethnic minorities and older adults.Methods We leveraged the National Health Interview Survey (NHIS) from 2016 (n=32 980), 2017 (n=26 700) and 2021 (n=28 740) to validate and develop analytical models for HICP. Initial models (2016 NHIS data) identified correlates associated with HICP, including hospital stays, diagnosis of specific diseases, psychological symptoms and employment status. We assessed the models’ generalisability and drew comparisons across time. We constructed five validation scenarios to account for variations in the availability of predictor variables across datasets and different time frames for pain assessment questions. We used logistic regression with Least Absolute Shrinkage and Selection Operator (LASSO) and random forest techniques. We assessed model discrimination, calibration and overall performance using metrics such as area under the curve (AUC), calibration slope and Brier score.Results Scenario 1, validating the NHIS 2016 model against 2017 data, demonstrated excellent discrimination with an AUC of 0.89 (95% CI 0.88 to 0.90) for both LASSO and random forest models. Subgroup-specific performance varied, with the lowest AUC among adults aged ≥65 years (0.81, 95% CI 0.78 to 0.82) and the highest among Hispanic respondents (0.91, 95% CI 0.88 to 0.94). Model calibration was generally robust, although underfitting was observed for Hispanic respondents (calibration slope: 1.31). Scenario 3, testing the NHIS 2016 model on 2021 data, showed reduced discrimination (AUC: 0.82, 95% CI 0.81 to 0.83) and overfitting (calibration slopes <1). De novo models based on 2021 data showed comparable discrimination (AUC: 0.86, 95% CI 0.85 to 0.87) but poorer calibration when validated against older datasets.Conclusion These findings underscore the potential of these models to guide personalised medicine strategies for HICP, aiming for more preventive rather than reactive healthcare. However, the model’s broader applicability requires further validation in varied settings and global populations. |
