This study aimed to investigate the intensity of needs for home health care services (HHCs) among elderly patients with chronic diseases and to identify the associated factors. A cross-sectional survey was conducted in Wuhou District, Chengdu, Sichuan Province, China, from April to November 2021. Convenient sampling was used to screen elderly patients with chronic diseases managed by Yulin Community Health Service Center. The questionnaires included general information and the Chinese version of the Community Healthy Intensity Rating Scale were completed according to patients' conditions. The data were analyzed using descriptive statistics and binary logistic regression. A total of 371 patients (10.40%) completed the survey. The mean age of the elderly patients was 84.04 years (SD=7.07); these patients suffered from 1 to 7 kinds of chronic diseases, and the most common were hypertension (78.98%) and diabetes (40.97%). The need intensity of patients for HHCs was moderate (41.51%) or severe (58.49%). For each additional chronic disease that patients suffered from, the need intensity increases by 1.289 times (OR=1.289; 95% CI: 1.055-1.575, p=.013); in additional, those aged more than 90 years, with a personal monthly income less than 2500 yuan ($387.00), with a poor health current status, and with only basic medical insurance presented greater need intensity (p<.05). Our data analysis revealed that economic status, insurance condition, poor health status, and multiple comorbidities may be the most common factors associated with the need intensity for HHCs. These characteristics may help medical staff to identify and help those with urgent health problems.
