Effect of Whole-Course Continuous Nursing Intervention Combined with a Nursing Practice Teaching Method on Quality of Life of Children with Functional Dyspepsia and Parents' Satisfaction Based on Smart Health

With the development of information technology, it has become a part of people's lives. WeChat is not only a popular chatting tool in daily life but can also be used in the medical field. Functional dyspepsia is a common pediatric disease, with complex pathogenic factors, which are usually attributed to abnormal gastric acid secretion and gastrointestinal dysfunction. In our research, we aim to investigate the effects of whole-course continuous nursing intervention combined with a nursing practice teaching method on the quality of life (QOL) of children with functional dyspepsia and parents' satisfaction. One hundred and twenty children with functional dyspepsia admitted to our hospital (February 2019–February 2020) were retrospectively analyzed and equally divided into the experimental group (EG) and the control group (CG) according to the order of admission. The CG received whole-course continuous nursing intervention, and the EG received whole-course continuous nursing intervention combined with the nursing practice teaching method. Children's psychological states and QOL and parents' satisfaction of both groups were compared. After discharge, compared with the CG, the negative emotion scores in the EG were remarkably lower (P < 0.001). After discharge, compared with the CG, the QOL scores (P < 0.001), the proportion of children with good and excellent QOL (P < 0.05), and parents' satisfaction (P < 0.001) in the EG were remarkably higher. For children with functional dyspepsia, whole-course continuous nursing intervention combined with the nursing practice teaching method can improve their negative emotions, QOL, and parents' satisfaction, which should be popularized in practice.

unchanged lifestyle after discharge, the disease can still be triggered by bad diet structure and psychological problems [4,5]. In this way, the recurrence rate of functional dyspepsia in a clinic is high [6,7], which poses a threat to children's physical and mental health. In order to reduce the recurrence rate of children after discharge, it is very important to take effective nursing measures. In practice, some scholars have applied whole-course continuous nursing intervention in children with gastric cancer and found that their quality of life (QOL) has been conspicuously improved within one year after discharge [8], which shows that this nursing mode can enhance the management efficiency and play the dual management role of psychology and physiology by focusing on the potential health problems of children [9]. Suffering from functional dyspepsia, the children have more severe negative emotions, together with poor treatment enthusiasm and gradually decreasing compliance after discharge [10,11], which is not conducive to the recovery of the disease. Due to the poor compliance of children, giving them all-around quality nursing intervention during treatment has been a clinical consensus [12]. is kind of nursing mode coordinates with the intervention during hospitalization, which finally improves patients' QOL [13]. In this study, after the whole-course continuous nursing intervention, the psychological state of the two groups was improved. Previous studies show that the immune system and gastrointestinal system are controlled by the neuroendocrine system [14].
At present, as clinical experience is little, no application of whole-course continuous nursing intervention in children with functional dyspepsia has been found. erefore, it is vital to choose the appropriate teaching method as the foundation. With constructivism as its core, the practice teaching method aims to integrate the theoretical knowledge of the whole-course continuous nursing intervention into practice, through which the nursing staff can improve their competency [15,16]. In this paper, the actual effect of wholecourse continuous nursing intervention combined with a nursing practice teaching method on children with functional dyspepsia was explored.

General Data.
A retrospective analysis of the data of children with functional dyspepsia admitted to our hospital (February 2019-February 2020) was conducted. e inclusion criteria were as follows: (1) Children's parents fully understood the research process and signed the consent form. (2) Children were diagnosed with functional dyspepsia by examination in accordance with the Rome IV Criteria for the Diagnosis of Functional Gastrointestinal Disorders in Children [17]. (3) Children were under the age of 10. (4) Children were diagnosed for the first time. e exclusion criteria were as follows: (1) children who had mental problems or could not be communicated with [18]; (2) children who had other digestive diseases, diabetes mellitus, hyperthyroidism, hematological diseases, cardiovascular diseases, and organ dysfunction [19]; and (3) children who were with extremely poor treatment compliance [20].
A total of 120 children were included in this study and equally divided into the experimental group (EG) and the control group (CG) according to the order of admission.
ere was no statistical difference in the children's general data between the two groups (Table 1). e study was approved by the hospital's ethics committee.

Withdrawal Criteria.
e withdrawal criteria were as follows: (1) Children who experienced adverse or serious adverse events were considered inappropriate to continue the experiment. (2) If children's conditions deteriorated during the experiment, it was considered inappropriate to continue to receive the experiment according to the doctor's judgment. (3) Children who had severe complications and special physiological changes were considered inappropriate to continue the experiment according to the doctor's judgment. (4) Children's parents who were unwilling to continue during the follow-up and asked the research group for a withdrawal from the clinical trial. e medical record sheets of the withdrawn cases were kept, but the data were not analyzed.

Methods.
e CG was given whole-course continuous nursing intervention. e specific steps were as follows: (1) Nurses built the whole-course continuous nursing intervention group for parents of children with functional dyspepsia. e head nurse was set as the administrator, and then experts and nutrition professors acted as instructors to formulate the whole-course continuous nursing guiding strategies. Nursing staff ought to communicate with the parents at the children's admission to gain their trust and invite them into the WeChat group with the name "Department + Name + Bed Number" for better information collection and management. Nursing staff also popularized relevant knowledge in the group to help the parents master the right home nursing methods and to enrich their knowledge. e parents could communicate with each other in the group and ask about the children's condition. en, nursing staff should answer the questions in time to help parents with home nursing, encourage them to share their children's recovery conditions in the group, and collect the information that could not be accessed in telephone followup so as to enhance the utilization efficiency of the WeChat group. (2) When the children were admitted to the hospital, the nursing staff mastered the children's information in detail and mapped out the nursing plans according to their actual situation. When the children were discharged, the nursing staff recorded the relevant information (children's name, contact information, family address, family members, and main family nursing staff) again, gave discharge guidance according to their recovery condition, and provided home nursing instruction handbooks. Children's parents were reminded to let children take acid-suppressive drugs and gastric mucosal protective agents on time, to feed gastroprokinetic drugs if children had a sense of fullness, to prepare soft clothes for keeping the abdomen warm, and to help children do physical exercise. Furthermore, due to the negative emotions in children with functional dyspepsia, children's parents were also informed about the importance of mental nursing, which was in need of conciliation in time. (3) e first telephone follow-up was conducted 3 days after discharge to see whether the children complied with the doctor's medication and had symptoms like abdominal pain and inappetence. en, the telephone follow-up was once a week. One month after discharge, it was changed to once a month, which was for one year. (4) Children with severe symptoms should be hospitalized immediately. For children with special conditions, nursing staff should follow up for doorto-door diagnosis and treatment using the vehicles provided by the hospital, so as to solve problems for the children's parents. (5) Regular lectures on health education were organized, and billboards in communities were set up to improve family members' understanding of functional dyspepsia. e nursing staff updated the lecture information on the billboards, inviting the children and their families to join in for learning and improving the quality of home nursing.
e EG was given whole-course continuous nursing intervention combined with a nursing practice teaching method, that is, to add a nursing practice teaching method on the basis of the CG. e specific steps were as follows: (1) A workshop was set up, and the teaching plan was formulated by the teachers. e specific teaching plan was described as follows: Opening remarks (role play or actual case introduction) introduced the topic of continuous nursing. General information of nursing practice teaching was provided. Learning objectives were formulated to enable nurses to grasp the knowledge about continuous nursing. Problems related to continuous nursing, functional dyspepsia, and pediatric nursing were put forward. Each problem was analyzed by the teachers, and then new problems were put forward. e learning effects of nurses were investigated, and their ability to solve practical problems was evaluated. (2) Teachers should conduct role-play training for nurses before class to ensure that the scenario simulation can meet the expected requirements through which nurses can learn continuous nursing knowledge and apply it in practice. (3) Nurses should consult the relevant knowledge of continuous nursing and functional dyspepsia, analyze it combined with actual cases, put it into practice, and ask teachers about the problems in the next class, so as to improve their continuous nursing ability.

Observation Criteria
2.4.1. Psychological State. It was evaluated according to the self-rating anxiety (SAS) scale and self-rating depression (SDS) scale [21]. Each of the scales included 20 items, with a total score of 100 points. Higher scores indicated more severe negative emotions in children. e scale was completed by the children's parents before nursing (T 1 ), 3 months after discharge (T 2 ), and 1 year after discharge (T 3 ).

QOL.
It was evaluated according to the QOL scale for children and adolescents (QLSCA) [22]. e scale had 13 dimensions, such as self-satisfaction, teacher-student relationship, somatic feelings, peer relationship, parent-child relationship, exercise capacity, learning ability and attitude, self-concept, negative emotions, homework attitude, activity opportunistic, and life convenience, which formed 4 factors, namely, social psychological function, physical and mental health, living environment, and QOL satisfaction. e QLSCA score had 4 grades. 29 points and below indicated poor QOL, 30 to 59 points indicated medium QOL, 60 to 69 points indicated good QOL, and 70 points and above indicated excellent QOL. e scale was completed by the children's parents before nursing (T 1 ), 3 months after discharge (T 2 ), and 1 year after discharge (T 3 ).

Parents' Satisfaction.
e self-made scale of our hospital was used to evaluate the total satisfaction of nursing and the satisfaction of health education, follow-up, online communication, and children's rehabilitation, with the score of each part being between 0 and 10 points. Higher scores indicated a higher degree of parents' satisfaction.

Statistical Processing.
In this study, the data were processed by SPSS20.0 and graphed by GraphPad Prism7 (GraphPad Software, San Diego, USA). Including enumeration data and measurement data, the study used the X 2 test and t-test. e differences were statistically significant at P < 0.05.

Comparison of the Psychological State of Children.
After discharge, compared with the CG, the negative emotion scores of the EG were conspicuously lower (P < 0.001) (Figure 1).
Note. In Figure 1, the abscissa from left to right was T 1 , T 2 , and T 3 , respectively. In the figure, the line with dots was the EG, and the line with squares was the CG. # P < 0.001. Figure 1(a) was the SAS score. No obvious difference was found in the SAS scores at T 1 between both groups (60.12 ± 2.41 vs 60.23 ± 2.32, P > 0.05). e SAS scores at T 2 and T 3 in the EG were obviously lower than those in the CG (39.65 ± 2.52 vs 44.68 ± 3.20 and 19.10 ± 2.65 vs 25.65 ± 2.10, P < 0.001). Figure 1(b) was the SDS score. No obvious difference was found in the SDS scores at T 1 between both groups (62.65 ± 3.40 vs 62.54 ± 3.42, P > 0.05).
e SDS scores at T 2 and T 3 in the EG were obviously lower than those in the CG (38.24 ± 3.20 vs 49.65 ± 3.22 and 19.87 ± 1.22 vs 27.62 ± 2.01, P < 0.001).

Comparison of QOL.
After discharge, compared with the CG, the QOL scores (P < 0.001) and the proportion of children with good and excellent QOL (P < 0.05) in the EG were remarkably higher (Figures 2 and 3).
Note. In Figure 2, the abscissa from left to right was T 1 , T 2 , and T 3 , respectively, and the ordinate was QLSCA (points). In the figure, the black area was the EG, and the gray area was the CG. # P < 0.001. No obvious difference was found in QLSCA scores at T 1 between both groups (66.21 ± 5.65 vs 67.10 ± 5.47, P > 0.05). e QLSCA scores at T 2 and T 3 in the EG were obviously higher than those in the CG (88.65 ± 6.10 vs 70.68 ± 2.34 and 90.10 ± 6.41 vs 82.68 ± 6.15, P < 0.001).

Comparison of Parents' Satisfaction.
Compared with the CG, the satisfaction of parents in the EG was obviously higher (P < 0.001) ( Table 2).

Discussion
Functional dyspepsia is a common disease in the pediatric digestive outpatient department, which is featured with a high recurrence rate, a long course of disease, and long-term treatment. e disease is usually caused by the abnormal secretion of gastrointestinal hormones. Some children are complicated with psychological problems. As we know, nursing intervention after discharge is helpful to improve the nutritional awareness of children and their parents, increase their disease cognition, and then decrease the recurrence rate. Continuous nursing is a common clinical nursing mode in recent years, which emphasizes more patients' potential health problems and the intervention of both physical and mental state. e negative emotions of children will affect their gastrointestinal function and even greatly impair their immunity. On the contrary, the alleviation of negative emotions indicates that the pathogenic factors of functional dyspepsia are reduced, the immunity is improved, and the disease is not easy to relapse.
However, it is not clear whether continuous nursing should be carried out for children after discharge. Some studies show that, after discharge, children still have bad eating habits and psychological problems [23,24]. Longterm malnutrition seriously affects the physical and mental development of children. As the whole-course continuous     Journal of Healthcare Engineering nursing intervention has not been applied in children with functional dyspepsia before, this study especially took nursing practice teaching as the support, in which the nurses had a deeper cognition of functional dyspepsia. Scenario simulation teaching and case teaching enabled nurses to master the characteristics of the disease and children's mental activity. Furthermore, nurses' perception, memory, and application abilities were fully improved, and they could clearly express themselves in health education and online communication, which yielded good results. e study showed that after discharge, compared with the CG, the negative emotion scores of the EG were obviously lower (P < 0.001). e reason is that the nursing staff experienced the emotional expressions of the children in the process of scenario simulation. Nurses put themselves in the place of children's parents to communicate with them, provided family nursing guidance from the perspective of children, and made full use of the active role of home nursing. e study carried out by El-Nagger N S et al., showed that the application of a practical teaching method in the nursing of children with pneumonia could comfort them and reduce their anxiety [25], which is consistent with the results of this study.

Conclusion
In our study, after one year's follow-up, compared with the CG, the scores of QOL in the EG were obviously higher (P < 0.05), and the proportion of children with good and excellent QOL was obviously higher (P < 0.05). e reason lies in that the nursing staff had paid more attention to humanistic care and professionalism through nursing practice teaching; therefore, the children's parents trusted more in nurses. One year after discharge, the children and their parents still had nursing compliance, and the recurrence rate of the disease was reduced. erefore, compared with the CG, the satisfaction of children's parents in the EG was obviously higher (P < 0.001).
In conclusion, for children with functional dyspepsia, whole-course continuous nursing intervention combined with nursing practice teaching method can improve their negative emotions, QOL, and parents' satisfaction, which should be popularized in practice.
