Objective. To explore the influence of PDCA cycle nursing based on network service on the quality of life and nutritional status of hypertension patients in home care. Methods. From January 2019 to December 2020, 116 hypertension patients in home care were selected as research objects. According to the random number method, the patients were divided into two groups: the control group (n = 58) and the observation group (n = 58). The control group was given routine home care service, while the observation group was given PDCA cycle nursing based on the network service. The effects of blood pressure control, quality of life, nutritional status, and emotional state of the two groups were analyzed. Results. The effective rate of blood pressure control in the observation group (93.10%) was higher than that in the control group (79.31%) ( P < 0.05 ). After intervention, the Generic Quality of Life Inventory-74 scores of the observation group were higher than those of the control group ( P < 0.05 ). After intervention, the malnutrition-inflammation score of the observation group was lower than that of the control group ( P < 0.05 ). After the intervention, the Self-Rating Anxiety Scale score and Self-Rating Depression Scale score of the observation group were lower than those of the control group ( P < 0.05 ). Conclusion. PDCA cycle nursing based on network service has a good blood pressure control effect on hypertension patients in home care, which can improve their quality of life and nutritional status and also relieve their bad emotions.
