Factors Influencing Readiness for Hospital Discharge among Patients Undergoing Breast Cancer Surgery

Background: Breast cancer has become an important disease burden harmful to women’s health. The treatment of breast cancer is mainly surgical treatment. In the context of enhanced recovery after surgery, the average length of hospital stay has been reduced, so there is increasing concern about postoperative patient discharge readiness. Objective: To identify factors influencing readiness for hospital discharge among patients having undergone breast cancer surgery and to explore the relationship between discharge readiness and the quality of discharge teaching. Methods: A total of 99 patients after breast cancer surgery at a regional tertiary medical tumor center in Guangzhou between June 2021 and December 2021 were collected using the convenience sampling method. A general data questionnaire, readiness for hospital discharge scale, and quality of discharge teaching scale were used to conduct a questionnaire survey on the subjects. Results: 83.8% of the patients feel ready for discharge, and the score of discharge readiness was 155.98 ± 28.87. The patients’ content received and the skills in teaching delivery were the influencing factors of discharge readiness. Discharged with a drainage tube was an independent factor of discharge readiness. Conclusions: Readiness for hospital discharge among patients undergoing breast cancer surgery was above medium level, and perfect intervention measures should be formulated for the influencing factors of discharge readiness. Especially, specific executable safeguard measures should be formulated for patients who are discharged early after surgery to promote the safety of home care.


Introduction
Breast cancer is the malignant tumor with the highest incidence in women, and the number of new cases has been increasing in recent years, which has become an important disease burden harmful to women's health [1] [2]. The treatment of breast cancer is mainly surgical treatment. In the context of enhanced recovery after surgery [3] [4] [5], the average length of hospital stay for breast cancer patients undergoing surgery has been reduced to 6 -14 days, so there is increasing concern about postoperative patient discharge readiness. Discharge readiness refers to the ability to leave the hospital, return to society, and further recover [6], which significantly impacts patients' health and quality of life. The quality of discharge teaching is an important factor affecting discharge readiness [7] [8] [9] [10]. Currently, domestic studies on discharge readiness and quality of discharge guidance for breast cancer patients and their influencing factors are gradually being carried out. Discharge readiness is a key stage for patients to transition to home care after discharge and the quality of discharge teaching correlates positively with discharge readiness that was already known about the topic. We show that discharge with or without drainage tube and the quality of discharge teaching are the influencing factors of discharge readiness, and the patients' content received and the skills in teaching delivery were the influencing factors of discharge readiness. The purpose of this study was to evaluate patients' reported readiness for discharge and the quality of discharge teaching, to explore the influence factors of discharge readiness, to improve the implementation of the clinical path for patients discharged from hospital readiness, and provide a basis for intervention measures. To ensure breast cancer patients are ready to be discharged, improve the ability of home nursing. Ensure that postoperative breast cancer patients have access to lobbyists to protect their safety and quality and to improve patient satisfaction.

Methods
In this study, the convenience sampling method was used to select patients who underwent breast cancer surgery at a regional tertiary medical tumor center in Guangzhou between June 2021 and December 2021.

Participants
Inclusion criteria: 1) age 18 -70 years, 2) primary school education level and above, being able to read and write in the Chinese language and complete the survey questionnaires, 3) pathological diagnosis of breast cancer and surgical treatment, and 4) informed consent and voluntary participation in this investigation.
Exclusion criteria: 1) Patients who were readmitted due to disease recurrence or disease progression, 2) patients with mental disorders or cognitive disorders, and 3) patients with severe physical diseases. the perioperative period. Routine education included postoperative bed activity and out-of-bed activity guidance, patients eating high-protein light meals and avoiding eating foods that promote blood circulation and remove blood stasis and contain estrogen, postoperative limb protection, and functional exercise, and proper fixing of the drainage tube. Discharge teaching included cleaning, disinfection, and dressing change of surgical wound, observation and treatment of postoperative complications, out-of-hospital anti-tumor treatment process, etc.

Readiness for Hospital Discharge Scale (RHDS)
The RHDS, was developed by Weiss et al. [11] [12] and translated into Chinese by Liu et al. [13], which was used to evaluate the extent to which patients are fully prepared in terms of personal status, knowledge, coping ability, and expected support. The scale contains 23 items instruments of 4 parts. Item 1 is a general question about whether the patient is ready for discharge, which is not included in the total score. The other 22 items are all scored by 0 -10, and items 3 and 6 are reverse scoring items. The total score on the scale ranged from 0 to 220, and the higher the score, the better the discharge readiness. Cronbach's α coefficient and content validity were 0.933 and 0.910 respectively. In this study, the Cronbach's α coefficient of the scale was 0.929, indicating good internal consistency of the scale.

Quality of Discharge Teaching Scale (QDTS)
The QDTS developed by Weiss et al. [11] and translated into Chinese by Wang et al. [14], was used for measurement. It is an 18-item instrument of 3 parts and the patients reported the contents they thought needed before discharge, the contents they obtained, and the teaching skills and effects. The first two parts are paired items. By comparing the difference between the score of the content obtained and that needed, we can know whether the content of discharge guidance meets the needs of patients. The scale uses 0 -10 points-scoring method. The whole scale measured the quality of discharge teaching by calculating the total score of the two parts of actual content acquired before discharge, teaching skills, and effect. The higher the total score, the better the quality of discharge teaching.
The Cronbach's α coefficient and content validity of the scale were 0.977 and 0.900 respectively. In this study, the Cronbach's α coefficient of the scale was 0.898 -0.960, indicating good internal consistency of the scale.

Demographic Characteristics and Disease-Related Information
A questionnaire designed by the researcher, including demographic characteristics and disease-related information. The demographic characteristics included age, sex, marital status, education level, working status, mode of medical payment, per capita monthly income of the family, place of residence, and mode of residence. The disease-related information included tumor grade, length of stay, and discharge with a drainage tube.

Data Collection
According to the inclusion and exclusion criteria, patients were screened in the inpatient area of the department of breast, and the purpose and content of the study were introduced in detail to obtain the informed consent of patients. Study questionnaires were distributed to patients on the day of discharge, and patients were instructed to fill in the questionnaires using unified instructions. The questionnaires took 10 to 20 min to complete. The questionnaire was collected and checked the completeness on the spot.

Data Analysis
Means and standard deviations were used to describe continuous variables, and frequencies and percentages were used to describe categorical variables. The differences in general data and disease-related data between the two groups were analyzed by t-test or chi-square test. The T-test was used to analyze the differences in discharge readiness and quality of patient evaluation of discharge guidance between the two groups. The statistical test standard was 0.05.

Demographic Characteristics and Disease-Related Information
A total of 99 patients were enrolled, and all of them were female, with a mean age was 48.7 (10.9) years and the mean length of hospitalization stay was 9.9 (3.9) days.

Score for Readiness for Hospital Discharge
The results showed that 83 patients (83.8%) feel ready for discharge, and the score of the patients' discharge readiness was 155.98 (28.87). The mean scores for the four dimensions from high to low were: knowledge (57.75 ± 13.79), personal status (50.82 ± 9.72), expected support (25.10 ± 74.79), coping ability (22.23 ± 5.63) ( Table 1).

Single-Factor Analysis of Demographic Characteristics and Disease-Related Information and Discharge Readiness Scores of Patients after Breast Cancer Surgery
The total score of the patient's discharge readiness was taken as the dependent variable, and the patient's age, education level, marital status, working status, per capita income of the family, payment method of medical expenses, family residence, residence style, tumor grade, length of hospitalization, and discharge with drainage tube were taken as the independent variables. The results showed that the total score of discharge readiness was statistically different in patients discharged with or without drainage tubes (P < 0.05) ( Table 2).   we compared four modules. The results show that the total content coefficient is 1.47 (P < 0.001), the coefficient of teaching skill and quality in model 3 was 9.71 (P < 0.001), and the coefficient of total discharge guidance quality score in model 4 was 0.656 (P < 0.001), both had statistical significance ( Table 3, Table 4).

The Total Score of Discharge Readiness Was above Average
Discharge readiness is a key stage for patients to transition to home care after discharge [15]. Discharge readiness is a prediction of whether patients are safe during the transition period after discharge. A good discharge readiness can not    [19]. The results of this study showed that the total score of discharge readiness for breast cancer patients (155.98 ± 28.87) was lower than the total score of discharge readiness for breast cancer patients (160.74 ± 25.60) reported by Liu et al. [20] and even lower than the score of discharge readiness for lung cancer patients (170.07 ± 29.79) reported by Liu et al. [13]. In this study, patients' discharge readiness was above average. Results showed that 16 of the 99 patients chose "no" on the

Analysis of Influencing Factors of Patients' Discharge Readiness
In the analysis of influencing factors of readiness for hospital discharge among patients undergoing breast cancer surgery, we compared four modules. In the comparison of general data, age, education level, marital status, working status, family per capita income, living style, tumor stage, and length of stay, there was no statistical significance (P > 0.05). However, discharge with a drainage tube had an impact on discharge readiness (P < 0.01). This may be due to the self-perception of discharge readiness of patients, who are concerned about whether the replacement memory will fall off due to the carrying of a drainage tube. In models II, III, and IV, a single-factor analysis was conducted on the total content instruction skill and the quality of discharge instruction quality score on the discharge instruction quality scale had statistical significance (P < 0.01). This shows that it is of practical significance for patients to obtain discharge guidance from nurses during hospitalization. In QDTS, the content obtained by patients (48.26 ± 11.34) did not meet the content they thought needed (49.35 ± 12.11), indicating that the routine perioperative health education and discharge teaching for breast cancer patients during hospitalization did not meet the expectations of patients, which may also be the reason for the low discharge readiness. In the process of clinical nursing, it is necessary to constantly improve and perfect the content of propaganda and education, and improve the skills and quality of discharge guidance of nurses.

Limitation
The research sites selected in this study are relatively limited due to external conditions, including time and space constraints. Only one tertiary hospital was selected. In addition, we were not following non-random sampling methods. Therefore, future research should add the type of non-random sampling.

Conclusion
Discharge with or without a drainage tube and the quality of discharge teaching are the influencing factors of discharge readiness. The level of readiness for hospital discharge among patients undergoing breast cancer surgery was positively correlated with the discharge teaching ability of nurses. Moreover, discharge preparation has a positive impact on patients' transitional home care. This study suggested that the discharge readiness of patients was above medium level. In the process of clinical nursing, nurses should strengthen the discharge education of patients with drainage tubes, and strengthen the teaching tools and skills. So as to provide the basis for the development of evidence-based intervention paths for discharge readiness, to ensure the nursing level of patients outside the hospital, to improve the management efficacy of single breast disease, and to improve life satisfaction and quality of life.
