3.1 Necessity of continuous nursing intervention for patients with anterior rectal resection with prophylactic terminal ileostomy
Prophylactic colostomy is generally performed approximately 3 months after surgery, and some patients face problems such as increased defecation frequency, poor defecation control ability, and incomplete defecation. Although colostomy complications affect the timely repayment of prophylactic colostomy, many complications can be effectively prevented through correct nursing with shortened hospitalization time. It is difficult for patients and their families to master professional colostomy nursing during hospitalization; therefore, continuous nursing is vital for preventive colostomy patients. Presently, there is a serious deficiency in the number and proportion of community nurses in our country, a lack of stoma specialist nurses, and patients with a high degree of trust in large hospitals. In addition, there is a certain demand for the continuation of previous therapeutic sexual relationships. Therefore, the continuous nursing model is based on the hospital-community-family ternary linkage model [15], which extends the hospitalization service to the family and community and is the concern and response to the patient’s health problems and needs during the transfer period. Paying attention to the problems related to the quality of life of patients with anterior rectal resection and preventive colostomy is the most feasible and necessary for patients with anterior rectal resection and preventive colostomy at the present stage.
3.2 Continuous nursing intervention under the guidance of the health belief model can improve the colostomy adaptability and self-efficacy of preventive colostomy patients
This study shows that through continuous nursing intervention under the health belief model, colostomy adaptability and self-efficacy scores in the observation group were higher than those in the control group after 3 months, which is consistent with the results of Yao et al. [16]. Self-efficacy refers to an individual’s expectation of the ability to accomplish specific tasks [17]. The self-efficacy of patients undergoing colostomy consists of two aspects: social function and colostomy management function. According to the health belief model, this study adopted a variety of follow-up models and multiple information channels to educate and strengthen the relevant knowledge of colostomy diet, activity, pocket replacement, prevention and management of complications, etc., make patients clear about the importance of correct nursing methods in preventing complications and improving the quality of life, promote patients to have health beliefs, and enhance their confidence in nursing colostomy. Thus, patients can better integrate themselves into their social lives. By enhancing patients’ sense of self-efficacy and improving their confidence in dealing with diseases, they can accelerate the self-adaptation process and reduce their psychological and social burden. Through continuous nursing education, patients can fully understand the disease, improve disease awareness, and make the patients adjust their ability to adapt to the environment, including physical, psychological, and social aspects. The results showed that although the adaptation score in the observation group was significantly higher than that in the control group, it was still low, which may be related to the temporary characteristics of preventive colostomy. Many patients believe that their stoma exists for a short time and depend too much on their families.
3.3 Continuous nursing intervention under the health belief model can improve patients' compliance with levator ani muscle training and improve defecation function
The results of this study showed that exercise compliance was higher in the observation group than in the control group after the intervention. Levator ani muscle training refers to the recovery of the muscle and its innervation nerve function through active contraction of the pelvic floor muscle to control voiding and defecation function. It usually takes 3–6 months after prophylactic colostomy. Long-term adherence to levator anus muscle training can effectively improve defecation function. The health belief model helps patients form correct cognitions and promotes the independent adoption of healthy behaviors. During this period, we mainly followed up and intervened by telephone to allow patients to fully understand the benefits of adhering to levator anus training and mastering correct training methods. The reasons for failure to adhere, such as physical and psychological factors, were analyzed according to different reasons for personalized guidance. Patients were urged to adhere to levator anus training to improve compliance.
3.4 Effect of continuous nursing intervention under the health belief model on the incidence of colostomy complications
The excretion of enterostomy is large, and the excreta contains a variety of digestive enzymes, which are more irritating to the skin; in addition, the position of the proximal opening of some double-lumen stomas is relatively low, close to the skin, making nursing more difficult. Improper nursing leads to fecal dermatitis after leakage, which affects pocket adhesion, forming a vicious circle [18]. As prophylactic colostomy is generally accepted approximately 3 months after surgery, many patients do not attach importance to the study of colostomy nursing methods and mostly rely on their family members for colostomy nursing. After colostomy, some patients also face problems such as increased defecation frequency, poor defecation control ability, and inexhaustible defecation. In the traditional nursing model, patients cut off contact with the hospital immediately after discharge. Once complications occur, the readmission rate is high, medical expenses increase, and even affect the timely repayment of preventive colostomies. Many complications can be effectively prevented through correct nursing; however, with the shortening of hospitalization time, it is difficult for patients and their families to master professional colostomy nursing during hospitalization. Therefore, continuous nursing care is essential for patients undergoing prophylactic colostomies. This study showed that the number of colostomy-related complications in the observation group was lower than that in the control group from post-colostomy to 3 months after discharge. Continuous nursing based on the health belief model adopts various forms of follow-up to solve the action obstacles of health behaviors and promote health beliefs, which can effectively reduce the occurrence of colostomy complications.
3.5 Effect of continuous nursing intervention on patients' quality of life under the health belief model
Even if preventive colostomy exists for a short time, it still impacts patients’ psychological, physiological, and social communication. Some patients in the survey said they were unwilling to go out for daily social activities before the colostomy was returned. After the intervention, the quality of life scores in the observation group were higher than those in the control group in terms of psychological burden, colostomy management, daily life, and social communication; the psychological burden and social communication scores in the observation group were significantly higher than those in the control group. The continuous nursing group built a good platform for colostomy patients through a network QQ group, and communication among the peers of patients who underwent colostomy, alleviating their feeling of loneliness. Faced with a colostomy, standardized telephone follow-up can provide timely psychological counseling for patients with psychological problems, make them more likely to accept themselves, form a good state of mental health, improve their self-care ability, and improve their quality of life.
