Epidemiological characteristics and hospitalization cost of lymphoma patients: an analysis of a single center / 白血病·淋巴瘤

ABSTRACT

Objective:To analyze the data of clinical characteristics, hospitalization actual cost and hospital stay of inpatients with lymphoma, and to provide references for local epidemiological research, hospital optimization management, and appropriate resource allocation.Methods:The quadratic programming was performed based on hospital information management system and case system, as well as the information from inpatients with lymphoma in Shandong Tai'an Central Hospital between January 1, 2004 and November 30, 2019, and then they were derived and collected into the SQL server database. The gender, onset age, age distribution, and hospital stay of all inpatients with lymphoma were retrospectively analyzed. The patients were divided into the young group (< 45 years old), middle-aged group (≥45 years old and < 60 years old) and elderly group (≥ 60 years old) according to the age. The hospitalization cost and hospital stay of these inpatients in different age groups were collected and compared.Results:The number of admissions for inpatients with lymphoma between January 1, 2004 and November 30, 2019 was 3 866, accounting for 0.38% (3 866/1 011 627) of the total inpatient admissions. There were 817 newly-diagnosed lymphoma inpatients, including 499 males and 318 females (male to female ratio was 1.571). The median onset age of the newly-diagnosed lymphoma inpatients was 58 years old (7 months to 86 years old). Among the newly-diagnosed lymphoma patients, the proportion of them with age ≥ 45 years old was increased, and peaked at 60-65 years old, and decreased after 75 years old. There were 180, 270 and 367 cases in the young group, middle-aged group and elderly group respectively; the median hospital stay was 13.5 d, 13.0 d and 14.0 d, respectively (χ 2 = 0.419, P = 0.811). The median total cost of hospitalization was 9 846.39 yuan, 12 232.16 yuan and 14 022.36 yuan, respectively (χ 2 = 9.443, P = 0.009); and the median drug cost was 3 423.37 yuan, 3 523.62 yuan and 3 654.54 yuan, respectively (χ 2 = 2.202, P = 0.333); the ratio of median drug cost to the total cost was 44.80%, 40.49% and 34.58%, respectively (χ 2 = 6.512, P = 0.039). Conclusions:The number of lymphoma inpatients in Shandong Tai'an Central Hospital is on the rise. The incidence of inpatients with lymphoma is increased annually with older onset age. The total cost of inpatients was increased with the aging, but it has no obvious relevance with hospital stay. Middle-aged and elderly people are the target populations for disease control and prevention. Measures including screening, early diagnosis and early treatment should be enhanced.
