Objective To analyze the application effect of hospital-community-family extended care service in children with cough variant asthma（CVA）.Methods Ninety patients with CVA admitted to a hospital in Henan from January 2018 to November 2018 were enrolled.The patients were divided into the control group and the study group according to the admission time

with 45 cases in each group.The control group received routine nursing intervention

and the study group gave hospital-community-family extended care services on the basis of the control group.Compare the incidence of illness

medical expenses

length of hospital stay

number of hospitalizations

days of parental leave

and pre-intervention

post-intervention 1 year post-children′s Asthma Quality of Life Questionnaire（PAQLQ）score

and lung function indicators before and after treatment[1 st forced expiratory volume（FEV1）

forced vital capacity（FVC）].Results Compared with the control group

the number of cases

medical expenses

and hospitalizations were lower in the study group

and the length of hospital stay and family members were shorter（P<0.05）.Before the intervention

FEV1 and FVC of the two groups had no significant difference（P>0.05）;after one year of intervention

FEV1 and FVC of the study group were higher than that of the control group

with significant difference（P<0.05）.Before the intervention

there was no significant difference in the scores of emotional dimension

activity dimension and symptom dimension in PAQLQ between the two groups（P>0.05）;one year after the intervention

the scores of emotional dimension

activity dimension and symptom dimension in the two groups were higher than that before the intervention

and the differences between the two groups were statistically significant（P<0.05）.Conclusion Hospital-community-family extended care services are used in children with CVA to control asthma attacks

reduce family burden

improve lung function

and improve the quality of life of children.
