Patients were stratified into risk groups. The association between all-cause 1-year mortality and risk factors was screened by chi-squared test and manually reviewed by 2 clinicians. We calculated risk scores for individual patients using a gradient tree-based boost algorithm, which measured the probability of mortality within the next year based on the preceding 1-year clinical profile. Results: The development sample included 125,896 patients (72,572 women, 57.64{\%}; mean 74.2 [SD 7.7] years). The final validation cohort included 153,199 patients (88,177 women, 57.56{\%}; mean 74.3 [SD 7.8] years). The c-statistic for discrimination was 0.96 (95{\%} CI 0.93-0.98) in the development group and 0.91 (95{\%} CI 0.90-0.94) in the validation cohort. The mortality was 0.99{\%} in the low-risk group, 16.75{\%} in the intermediate-risk group, and 72.12{\%} in the high-risk group. A total of 99 independent risk factors (n=99) for mortality were identified (reported as odds ratios; 95{\%} CI). Age was on the top of list (1.41; 1.06-1.48); congestive heart failure (20.90; 15.41-28.08) and different tumor sites were also recognized as driving risk factors, such as cancer of the ovaries (14.42; 2.24-53.04), colon (14.07; 10.08-19.08), and stomach (13.64; 3.26-86.57). Disparities were also found in patients' social determinants like respiratory hazard index (1.24; 0.92-1.40) and unemployment rate (1.18; 0.98-1.24). Among high-risk patients who expired in our dataset, cerebrovascular accident, amputation, and type 1 diabetes were the top 3 diseases in terms of average cost in the last year of life. Conclusions: Our study prospectively validated an accurate 1-year risk prediction model and stratification for the elderly population (≥65 years) at risk of mortality with statewide electronic medical record datasets. It should be a valuable adjunct for helping patients to make better quality-of-life choices and alerting care givers to target high-risk elderly for appropriate care and discussions, thus cutting back on futile treatment.
