Abstract:
Objective To establish the demarcation norm of the patient-reported outcomes of hypertension, and provide evidence for clinical treatment. Methods Patients with hypertension diagnosed in 4 counties of 2 cities in Yunnan Province who were single-drug patients were randomly selected from April to June 2020. The questionnaire of hypertension patient-reported outcomes was completed, and the scores of the scale (PROISCD-HY) were calculated. After clustering analysis of the population, the clustering results were used as the basis for population division to establish a cut-off norm for the reported outcome scores of hypertension patients. Results The survey eventually collected 487 single-drug hypertension patients reported outcome questionnaires. The two-step cluster method was used to cluster analysis, and the respondents were divided into 4 categories by age and gender: 114 males aged ≥65, 89 males aged 18-64, 160 females aged ≥65, and 124 females aged 18-64. In the 4 groups, there were all statistical differences in other fields except the field of "Spirit/Belief" (P < 0.05), and the clustering was reasonable. A demarcation norm for patients reported outcomes of hypertension was construct with intervals of 0.5s and boundary points of (x±s) and (x± 0.5s), and determined as 5 states: [0, x-s) very poor, [x-s, x-0.5s) poor, [x-0.5s, x+0.5s) average, [x+0.5s, x+s) good, [x+s, 100) very good. The demarcation norm for the final total scores of the scale were: [0, 66.23), [66.23, 70.01), [70.01, 77.56), [77.56, 81.33), [81.33, 100). Among them, the scores of demarcation norm of the 18-64-year-old male were: [0, 70.08), [70.08, 73.50), [73.50, 80.34), [80.34, 83.76), [83.76, 100); the 18-64-year-old female were: [0, 68.19), [68.19, 72.08), [72.08, 79.85), [79.85, 83.73), [83.73, 100); the norm of ≥65-year-old male were: [0, 65.73), [65.73, 69.43), [69.43, 76.81), [76.81, 80.51), [80.51, 100); ≥65-year-old female were: [0, 64.15), [64.15, 67.49), [67.49, 74.17), [74.17, 77.51), [77.51, 100). Conclusion This study constructs a demarcation norm for patient reported outcomes and provides data support and evaluation reference standard for related hypertension research.
