Objective: To evaluate the efficacy of an education program on the prevention of febrile neutropenia (FN) among breast cancer patients receiving AC regimen. Methods: Randomized controlled trial with the repeated-measures design was conducted in a Chemotherapy Day Centre of an acute hospital in Hong Kong. Twenty-five subjects in the intervention group received an individual education session followed by three follow-up sessions and routine care. Twenty-four subjects in the control group received routine care. Primary outcomes included the incidence of admission due to FN, the self-care behavior adherence, the knowledge level on prevention of FN and the self-efficacy in self-management, handwashing competence were assessed by self-designed questionnaires, Chinese version of patient activation measure, and handwashing competence checklist. Results: No statistically significant difference between the intervention group and the control group on the incidence of admission due to FN, the self-efficacy in self-management, and the knowledge on prevention of FN. The self-care behavior adherence was significant at cycle 4 of AC regimen in favor of the intervention group (P = 0.036). Handwashing competence improved more significantly among subjects in the intervention group than the control group (P = 0.009). Conclusions: The education program on the prevention of FN had significantly favorable effects on self-care behavior adherence and handwashing competence across time. However, the intervention did not lead to statistically significant improvement on the incidence of admission due to FN, the self-efficacy in self-management and the knowledge level on prevention of FN.

| Introduction|| |
According to World Health Organization,  cancer was a leading cause of death worldwide, accounting for 7.6 million deaths in 2008. Breast cancer is the most common cancer in women worldwide.  According to Hong Kong Cancer Registry,  breast cancer was ranked first in the new cases registered among female patients in 2010. Doxorubicin and cyclophosphamide (AC) is one of the anthracycline-based regimens widely used as an adjuvant treatment for breast cancer.  However, the regimen of AC is associated with severe myelosuppression, nausea and vomiting, stomatitis, alopecia, and anorexia. , Among these side effects, myelosuppression is a life-threatening side effect because it predisposes patients to febrile neutropenia (FN) for early-stage breast cancer undergoing chemotherapy with substantial morbidity, mortality, and healthcare resources.  With the shifting of oncology services to outpatient settings, enabling the patients who are receiving chemotherapy to take care of themselves at home is of high importance for success in treatment and reducing patients' sufferings. As FN is a frequently occurring and potentially life-threatening complication of chemotherapy, providing education program on the prevention of FN to cancer patients receiving AC regimen is regarded as an important role of nurses.
Education programs on pain, fatigue, and prechemotherapy for cancer patients were shown to decrease side effects of treatment, improve self-care abilities, and enhance the quality of life. ,,,, Although there is no previous study on the efficacy of patient education program for the prevention of FN, a monthlong FN related education campaign was launched in a cancer center in the United States.  Poster, teaching sheets, and T-shirts were used to increase patient understanding of the definition and consequences of FN. After the campaign was initiated, a survey of 100 patients showed 80% improvement on the understanding of absolute neutrophil count (ANC) and 54% improvement on the definition of fever.
A systematic review of the literature regarding the effectiveness of various methods of information given to patients with cancer receiving chemotherapy education, revealed no statistical improvement in information recall and the area of quantity of self-care activities for using multimedia devices.  However, Kinnane and Thompson  concluded that patients who viewed the video in conjunction with standard chemotherapy education improve retention of information regarding management of predictable chemotherapy side effects and reporting of treatment-related symptoms.
Empowerment Process Model is incorporated in this study as the framework. The model defined empowerment as an iterative process in which a person sets a personally meaningful goal oriented toward increasing power, takes action toward that goal, and observes and reflects on the impact of this action.  The empowerment approach is particularly appropriate to be applied on the management of some kind of disease in which the recommended behavior changes involved deeply rooted aspects of a patient's daily life.  The model is chosen for cancer patients receiving chemotherapy because they require behavior modification in their daily lives in order to prevent neutropenic related infection. Moreover, the feelings of powerlessness, loss of control, and deteriorated health are almost inevitably followed from being diagnosed and treated for breast cancer.  Buffum  stated empowerment improves individuals' initiative to take actions for their health with hope, confidence, and a feeling of self-worth. Empowerment intervention may be a powerful agent to help participants to regain control, to make necessary changes to improve their lives during recovery  and thus was incorporated in this study.
| Methods|| |
Patients who require chemotherapy administration in Chemotherapy Day Centre between September 2012 and March 2013 was screened for eligibility to participate in the study by the researcher. All patients who fulfil the following inclusion criteria were invited:
- Aged 18 or above;
- Being breast cancer patients;
- Able to speak and understand Cantonese;
- Not receiving any chemotherapy before, and
- Undergoing the first cycle of AC regimen.
Exclusive criteria of the study included patients who were/had:
- Visual or hearing impaired;
- Known cognitive impairment;
- Known psychiatric illness, and
- Eastern Cooperative Oncology Group (ECOG) performance status  score greater than two.
Thus, the subjects who are unable to carry out self-care activities were excluded.
A two-arm (routine care vs. experimental intervention) randomized controlled trial with the repeated-measures design was conducted. Subject who agreed to join the study was assigned randomly into the control or the intervention group by using a computer-generated allocation sequence.  Each patient allocation was marked, folded and then placed in a sealed envelope, and allocation was provided by an independent person working in the department without knowledge of the patient or their medical history. Results of the study were collected at three time points which were at cycle 1 (T 0 ), cycle 2 (T 1), and cycle 4 (T 3) of the chemotherapy.
Control: Routine care
Subjects in the control group received routine care which was the existing care provided to all cancer patients in the study cancer center. A booklet was distributed to them prior to their chemotherapy administration. It composed of 23 pages and covered introduction of chemotherapy, common side effects of chemotherapy and its care, dietary suggestions, drip site care, logistic of chemotherapy administration, introduction of the cancer center, in-patient ward, and resource center. During the first consultation, an information sheet about AC was distributed to the subjects by the physician. The content of information sheet included the schedule of the regimen, common side effects, and some special points to note. The administration of AC was arranged in the evening on the same day. A 13-min standardized video session which explained the mechanism of AC, the administration method, the expected side effects of AC, and their self-help measures, how and when to seek medical help was broadcasted to them prior to the chemotherapy administration. The routine care focused on providing standard information. No follow-up or reinforcement of the information was provided to the patients.
Intervention: Education program on prevention of febrile neutropenia
Individual education sessions
Apart from the information given in the control group, a 30-min individual education session was provided by the researcher in a room to the subjects in the intervention group after the video session and before chemotherapy administration. A neutropenia education program protocol [Appendix A [Additional file 1]] was designed to empower the subjects to identify goals and values, understand how their behavior influences their health, develop knowledge, skills and confidence to make decisions about their health that best enable them to achieve the goals, and stay committed.  It provided standardized guidelines by the integration of the six key concepts in the Empowerment Process Model (i.e., goal, action, impact, self-efficacy, knowledge, and competence) into the five-steps of behavior change protocol which was the primary behavioral strategy used in empowerment-based interventions. 
Apart from the information given in the control group, the nurse also focused on enhancing individual patients' competence and self-efficacy so as to enable them to have proper self-care behavior on the prevention of FN. The education program emphasize on empowering patients to adopt behaviors to prevent FN in their daily lives. Researcher valued the two-way communication during the education session and follow-up sessions. The goal of the education program was mutually agreeable. Subjects were motivated to have behavior changes. Problems were usually identified by the subjects and were solved by themselves. Depend on the subject's behavior adherence, self-efficacy, competence and knowledge level, different dose of encouragement, reassurance, reinforcement, and support were provided. A neutropenia education program protocol and teaching cards were developed to assist the interventions given in a consistent way. The education program on the prevention of FN consisted of an individual education session and three follow-up sessions.
Follow-up sessions were scheduled each time when the subjects came back for the medical follow-up consultation and AC injection (i.e., cycle 2, cycle 3, and cycle 4 of AC regimen). A room was used to conduct the follow-up sessions. Same as the individual education sessions, the behavior change protocol was conducted.
The program was validated by five oncology expert panel members (one nurse educator, one nurse consultant, one ward manager, and two advanced practice nurses).
Data were collected using a structured questionnaire. Consistent with the Empowerment Process Model, the outcomes for the study included impact, self-efficacy, knowledge, competence, and action. There are four instruments including demographic data sheet, medical information sheet, neutropenia questionnaire, and handwashing competence checklist.
Demographic data sheet
A demographic data sheet [Appendix B [Additional file 2]] was used to collect the demographic data of the subjects. Personal information including age, gender, marital status, job nature, education level, household numbers, type of residential property, and size of living area were collected. It was a self-administered questionnaire.
Medical information sheet
The impact was assessed by the incidence of admission which was documented in medical information sheet [Appendix C [Additional file 3]]. Besides, medical information including diagnosis, staging of disease, use of granulocyte colony-stimulating factor (G-CSF) and antibiotic or antifungal prophylaxis, hemoglobin level, ANC, serum albumin level, comorbidities including liver, renal and cardiovascular disease, presence of open wound, previous or concurrent radiation therapy, and ECOG performance status were collected. These are the patient-related risk factors for developing FN.
The neutropenia questionnaire [Appendix D [Additional file 4]] consisted of three sections. Patient activation measure (PAM) for assessing self-efficacy in self-management was developed by Hibbard et al., in 2004.  The other sections in the questionnaire for assessing knowledge level on the prevention of FN and self-care behavior adherence were developed by the researcher and had validity and reliability tested before adoption. The content validity index for item relevance in the neutropenia questionnaire was one which indicated good content validity.  The Pearson's correlation coefficient of different sections of the questionnaire ranged from 0.723 to 0.976 which indicated strong to very strong association. 
Knowledge level on the prevention of febrile neutropenia
The first section is composed of 13 multiple choices questions for assessing the subjects' knowledge level on the prevention of FN including information of white blood cells, prevention of infection in environmental factors, dietary factors, personal hygiene, and management of neutropenic infection. These questions are developed according to the content of the education program.
Self-care behavior adherence
The second section of the questionnaire composed of 23 questions under the category of behavior adherence on personal hygiene, hand hygiene, dietary habit, and oral hygiene. It assessed the subjects' self-care behavior in the past 3 weeks. The questionnaire used a four-point Likert scale ranging from "Never," "Seldom," "Sometimes," and "Always." The overall behavior would be calculated by adding up all of the response to 23 questions (i.e., "Never" = 1, "Seldom" = 2, "Sometimes" = 3, and "Always" = 4). Reversal of score would be given on diet habit (i.e., "Never" = 4, "Seldom" = 3, "Sometimes" = 2, and "Always" = 1).
Self-efficacy in self-management
The third section of the questionnaire is the Chinese version of PAM. PAM was developed by Hibbard et al., to assess the activation which described as a state on a continuum ranging from believing that an active role is important, via having confidence and knowledge to take action, then taking action, and finally staying on the way under stress.  PAM is one of the cancer specific and self-management self-efficacy outcome measures.  It comprises 22 items to assess the patient's knowledge, skills, and confidence for self-management. The subjects rated their responses on a four-point Likert scale from "Strongly Agree," "Agree," "Disagree," or "Strongly Disagree." Extensive evidence has been reported in support of its reliability and internal consistency.  The Chinese version of PAM developed by Hsu  which had high internal consistency (the coefficient of Cronbach's alpha = 0.882) was adopted in the study. The total score would be calculated by adding up all of the responses to the 22 questions (i.e., "Strongly Disagree" = 1, "Disagree" = 2, "Agree" = 3, and "Strongly Agree" = 4). Reversal of score would be given to question number 22 (i.e., "Strongly Disagree" = 4, "Disagree" = 3, "Agree" = 2, and "Strongly Agree" = 1).
Handwashing competence checklist
South Staffordshire Primary Care Trust provides a handwashing competence checklist [Appendix E [Additional file 5]] for assessing the handwashing competency for local communities. There are 14 criteria to be assessed during the handwashing which were consistent with the pamphlet produced by the Department of Health in Hong Kong.  For scoring of each item in this part, "1" mark was scored for those meetings the criteria and "0" mark for those not meeting the criteria. Subjects who obtained 14 marks were considered as competent according to the handwashing competence checklist.  Intra-rater reliability test for handwashing competence checklist was checked, and the result of intraclass correlation coefficient was 0.985.
Statistical Package for the Social Sciences (SPSS) version 17.0 for Windows developed by IBM Corporation was used in data analysis in this study. The level of statistical significance for this study was set at 95% (P ≤ 0.05). Independent sample t-test and Mann-Whitney U-test were used to compare the means of knowledge scores between the intervention group and the control group at three time points (T 0 , T 1 , and T 3). The data of self-care behavior action and the data of the Chinese version of PAM were analyzed by Mann-Whitney U-test to compare the data between the groups at three time points (T 0, T 1, and T 3). To evaluate the handwashing competence and incidence of admission due to FN between the groups, a Chi-squared test was used to compare the result at T 0 and T 3 and T 4 , respectively.
The study was reviewed and approved by the Research Ethics Committee of related hospital and the Human Subjects Research Ethics Committee of the Hong Kong Polytechnic University. The written informed consents were obtained from all subjects before commencing the study. In order to ensure confidentiality and anonymity, the participation and responses of the subjects in the study were kept confidential, and all the data were locked in a drawer. Anonymity was ensured on the instruments. The subjects had the right to withdraw from the study at any time without penalty. Moreover, permission for using the Chinese version of PAMs was obtained from the author.
| Results|| |
Fifty subjects were recruited in the study with 25 in the control group and 25 in the intervention group. The demographics of the subjects are listed in [Table 1]. There were no statistical differences between both groups in demographic characteristics. The age of subjects ranged from 37 to 68 years, with a mean age of 52.7 years (standard deviation = 7.4 years). Most of the subjects in the study were married. Most subjects were educated to primary and secondary school level and were housewife. Many of the them lived in a public housing estate. One subject in the control group dropped out after the first cycle of AC due to the discontinuity of chemotherapy. Regarding the use of G-CSF, a statistically significant difference was observed between the groups at cycle two and three (χ2 = 4.35; df = 1; P = 0.037). Four subjects (16%) in the control group were prescribed G-CSF on day 5 from the beginning of chemotherapy since cycle 2 while one subject in the intervention group was prescribed the G-CSF at cycle 4 [Table 1].

Incidence of admission due to febrile neutropeniath
There was no significant difference between two groups in term of admission due to FN. The result was checked at 3 weeks after chemotherapy completion (T 4 ). During the AC chemotherapy regimen, 6 out of 25 subjects (24%) in the control group were admitted due to FN while 3 out of 25 subjects (12%) in the intervention group were admitted because of FN [Table 2].

Self-care behavior adherence
The overall behaviors were divided into four categories including personal hygiene, hand hygiene, diet hygiene, and oral hygiene. Compared by using Mann-Whitney U-test, there was no significant difference on overall behavior between the groups at T 0 and T 1, but significant difference was found at T 3 . Subjects in the intervention group had higher scores comparing with those in the control group at T 3 [Table 3].

Self-efficacy in self-management
The result on self-efficacy in self-management showed that there was no significant difference between the intervention group and the control group at T 0 , T 1 , and T 3 by using Mann-Whitney U-test. [Table 4] demonstrated that the subjects in the control group showed an increase in self-efficacy at T 1, but the mean score dropped slightly at T 3. For the intervention group, the intervention increased the subjects' self-efficacy at T 1 with a further increase at T 3.

Knowledge level on prevention of febrile neutropenia
There was no significant difference between the groups at T 0 , T 1 , and T 3. The knowledge score in both the control group and the intervention group increased significantly across time [Table 5].

Handwashing competence was assessed at T 0 and T 3 only. Chi-squared test was performed to determine the between-group comparison at the two time points. All the subjects in both groups did not pass the handwashing competence test at baseline assessed by the handwashing checklist. There was a significant difference in handwashing competence at T 3 . Six subjects in the intervention passed the competent test while none of the subjects in the control group passed the test after the education program, as displayed in [Table 6].

| Discussion|| |
This study examined how an educational program could increase the self-care behavior adherence, handwashing competence, incidence of admission due to FN, knowledge level on prevention of FN, and self-efficacy in self-management among breast cancer patients receiving chemotherapy.
Initially, both the control group and intervention group were shown to result in improving the self-care behavior adherence. Yet, the number of subjects in the intervention group reporting self-care behaviors had increased, whereas the number of subjects in the control group reporting self-care behaviors had decreased at the cycle 4 of chemotherapy. This finding is consistent with previous studies that individualizing is a favorable technique for encouraging the greater performance of health-related behaviors.  Wilson  stated that matching instructional methods to individual readiness to learn, learning style, and learning speed are generally regarded as desirable and more likely to be effective in changing patient's behavior. In contrast, audio - or videotape patient education program even typically designed for delivery to individual patients is inflexible across individual differences.
Moreover, subjects in the intervention group experienced improvement in handwashing competence that did not occur in the control group. Demonstration and return demonstration of handwashing technique was performed to the subjects in the intervention group individually. This is consistent with Wilson's  study that individual instruction is an appropriate teaching method for technical skill training. Demonstrations served to enhance the memorial representation of the required sequence and movement. 
One of the most surprising findings in the study related to the admission rate due to FN. The admission rate of subjects in the intervention group was half of that for the control group. It might reflect the positive effect of the intervention on the admission rate due to FN. However, more studies on admission and preventive measures for FN among cancer patients receiving myelosuppressive chemotherapy should be conducted. In addition, one subject in the control group did not seek medical help even with high fever and waited until medical follow-up appointment. The importance of prompt reporting of fever should be emphasized for those subjects receiving myelosuppressive chemotherapy. According to Best et al.,  initiating antibiotic therapy in a timely manner is important to treat FN because the delay in treatment can increase the patient's risk for sepsis and death. In the study, 27% of the subjects did not know the temperature at which they should seek medical help. Patients should know the signs and symptoms of FN and how to prevent infection. , Lack of knowledge was one of the patient-related variables which can be eliminated through the education program. In this study, the mean score in the intervention group increase much more than the control group across time. This finding is consistent with previous studies that inclusion of video to standard chemotherapy education improves retention of information regarding management of predictable chemotherapy side effects and reporting of treatment-related symptoms. 
Lastly, the finding revealed that self-efficacy in self-management in the intervention group had increased across time, whereas the self-efficacy in the control group had increased initially then decreased slightly across time. Empowerment strategies have demonstrated their effectiveness in self-efficacy and patient activation. ,, Funnell et al.  developed a five-step behavior change protocol which is the primary behavioral strategy used in the empowerment-based interventions. This protocol resulted in significant improvement in self-efficacy in diabetes self-management behavior.  However, there was a lack of study investigating the effect of an empowerment-based education program on self-efficacy in self-management among cancer patients to prevent FN. This is an area that needs to be explored in the future study.
| Limitation|| |
The limitations in this study cannot be neglected. First, the small sample size increased the possibility of sampling error which would lead to a meaningless or misleading result.  Moreover, subjects were not blinded to the intervention they received. Hawthorne effect might happen in the study. Lastly, cross-contamination of the data between subjects in the different group cannot be absolutely excluded.
Implications to nursing practice
This study is the first study to apply Empowerment Process Model on neutropenia-related education program. It provide insight for guiding nurses in adopting the systematic education program and developing a protocol for neutropenia care education program into their daily clinical practice, so as to prevent chemotherapy-induced FN among patients receiving chemotherapy with high or intermediate risk of developing neutropenia.
Results of this study suggests the use of demonstration and return-demonstration for teaching practical skills such as handwashing and the use of individual education program on self-care behavioral adherence could be adopted in the future education program.
| Conclusion|| |
The education program on prevention of FN had significantly favorable effects on self-care behavior adherence and handwashing competence across time. The intervention might have positive effects on the incidence of admission due to FN, the knowledge level on prevention of FN and the self-efficacy in self-management but statistically significant differences were not demonstrated. FN has major negative impacts on patients. This study do provide insight for guiding nurses in adopting the systematic education program into their daily clinical practice, so as to prevent chemotherapy induced FN among patients receiving chemotherapy with high or intermediate risk of developing neutropenia.
