ObjectiveTo analyze the impact of high-quality nursing care on adult patients with asthma and asthma control. MethodsWe randomly chose 100 patients with asthma from June 2012 to July 2013, and the patients were randomly divided into experimental group (n=50) and control group (n=50). Patients in both the two groups received treatments based on the characteristics of the patients' condition. The control group received conventional care, while the experimental group received high-quality nursing care aimed to help them establish the concept of Asthma Prevention on the basis of the conventional care. Then, we analyzed the effect of nursing intervention in both groups. ResultsBefore the treatment, the forced expiratory volume in 1 second (%) and peak expiratory flow were not significantly different between the two groups (P>0.05). After treatment, both groups had improvement in their lung function. However, improvement in lung function of the experimental group was significantly better than the control group (P<0.05). The disease remission level in the experiment group and the control group was respectively 86.0% (43/50) and 64.0% (32/50) (χ2=6.453, P=0.011). According to the Asthma Control Questionnare (5-item version), in the experimental group, 46 patients completed the assessment and the total control of asthma accounted for 34.8% (16/46), well-controlled asthma accounted for 50.0% (23/46), and uncontrolled asthma accounted for 15.2% (7/46); while in the control group, 48 patients completed the assessment and the total control of asthma accounted for 18.8% (9/48), well-controlled asthma accounted for 43.8% (21/48), and uncontrolled asthma accounted for 37.5% (18/48) (Z=-2.533, P=0.011). The average hospital stay for the experimental group and the control group was respectively 11.24 days and 12.16 days. ConclusionHigh-quality nursing care can improve the quality of life of adult asthma patients, improve the patients' lung function, and enhance the control of asthma.
