Introduction: e aim of the study was to evaluate the usefulness of Identification of Seniors at Risk (ISAR) scale among elderly patients admitted to the department of internal medicine.
Material and methods: The ISAR score was performed among patients aged >59 years a er admission to the hospital ward. Data from medical history about diseases, taken medicines, falls, length of hospital stay and mortality were compared in patients with ISAR score of 0-1 and over 1 and in subjects with and without history of falls. Regression analysis was used to detect predictors of the length of hospital stay or death.
Results: The sample consisted of 102 subjects aged 80.9 ± 7.9 years, 45.5% of men, 34.6% had history of falls. The number of diseases was 11.3 ± 3.9 and number of medicines - 8.9 ± 3.7. The score of ISAR ≥2 was found in 90.2% of patients, length of hospital stay was 10.3 ± 8.4 days, mortality rate was 9.9%. Patients with ISAR score <2 were younger, showed a smaller number of diseases, used less drugs and had less frequency of falls than those with score ≥2. Patients with history of falls had higher mean ISAR score, higher number of diseases and medicines than the others. The increased number of diseases and higher ISAR score significantly influenced the length of hospital stay. None of the analyzed factors had any impact on mortality.
Conclusion: The score of ISAR scale together with number of diseases have a positive impact on the length of hospital stay.
