Predictive value of the Hemoglobin, Albumin, Lymphocyte and Platelet score for mortality in geriatric patients presenting to the emergency department.

Aim: The Hemoglobin, Albumin, Lymphocyte and Platelet (HALP) score, calculated as hemoglobin × albumin × lymphocytes / platelets, serves as a novel biomarker that can provide insights into a patient's nutritional status, anemia status and inflammatory processes. This study aimed to investigate the predictive value of the HALP score for mortality among geriatric patients presenting to the emergency department.

Methods: This retrospective study was carried out at the emergency department of a tertiary hospital. Patients aged ≥65 years who presented to the emergency department between 1 January 2018 and 1 January 2024 were included in the study. A total of 62 262 patients who visited our emergency department were enrolled. Patient data, including hemoglobin, albumin, lymphocyte and platelet values; age; sex, the reason for hospital presentation; and outcome (mortality or discharge) were obtained from electronic medical records. HALP scores were calculated for the patients, and statistical analyses were carried out.

Results: Of the patients, 32 410 were men, and the mean age was 73 years. Within this cohort, in-hospital mortality occurred in 3093 of the patients. The HALP score was significantly lower in patients who died compared with those who were discharged (P < 0.001).

Conclusion: Due to its cost-effectiveness and ease of calculation, the HALP score appears to be more feasible in predicting mortality in the emergency department compared with other scoring systems. Geriatr Gerontol Int 2025; ••: ••-••.
