A recently published study evaluated patients admitted in hospitals in Canada and in the United States for their risk of death within a year of hospitalization.
A study published in the Canadian Medical Association Journal evaluated patients admitted in hospitals in Ontario and Alberta, and in Brigham and Women's Hospital in Boston for their risk of death within a year of hospitalization. The researchers derived a formula or tool, which they have named as the Hospital patient One-year Mortality Risk (HOMR) score. HOMR score considers patient demographics, health burden, and severity of acute illness tp predict the risk of mortality.
Following validation of their tool, the researchers found that observed and expected outcomes of risk were similar when they used the HOMR score. The authors indicate that the score was not influenced by geographical location or the diversity of the population.
