<sec id="s1" sec-type="intro"><label>1.</label><title>Introduction</title>
<p>At present, about 70&#x0025; of perinatal diseases in neonatal wards worldwide occur in preterm infants (<xref ref-type="bibr" rid="B1">1</xref>). Preterm infants are at high risk of abnormal development, and effective intervention should be carried out as soon as possible to improve the quality of life of preterm infants (<xref ref-type="bibr" rid="B2">2</xref>).</p>
<p>Most preterm infants are admitted to the neonatal intensive care unit (NICU) after birth. After the child is admitted to the ICU, the whole family will go through a period of grief, especially the mother, who will show great pain and often develop post-traumatic stress disorder (<xref ref-type="bibr" rid="B3">3</xref>&#x2013;<xref ref-type="bibr" rid="B5">5</xref>). At the same time, the stress and uncertainty of neonatal admission to the NICU may persist after discharge and may contribute to the persistence of parental symptoms of depression and anxiety (<xref ref-type="bibr" rid="B6">6</xref>). Ensure that discharged preterm infants receive adequate care and stay healthy outside the hospital, how to improve the ability of family members to take care of their infants independently, distinguish and deal with abnormal conditions, and making them feel ready for discharge is a great challenge for all medical staff (<xref ref-type="bibr" rid="B7">7</xref>). Therefore, how to closely link doctors and nurses together to participate in the comprehensive nursing model is worthy of in-depth study.</p>
<p>Family-centered empowerment education models can enhance the family system, that is, empower the patient and other family members to improve the patient&#x0027;s health, and prevent diseases and complications (<xref ref-type="bibr" rid="B8">8</xref>, <xref ref-type="bibr" rid="B9">9</xref>). The implementation of the model was divided into perceived problem-solving, educational engagement, and assessment.</p>
<p>Based on the above, the purpose of our study was to explore the effects of the family-centered empowerment model on anxiety, care ability, and discharge readiness of family main caregivers by taking primary caregivers of premature infants as the research object.</p>
</sec>
<sec id="s2"><label>2.</label><title>Materials and methods</title>
<sec id="s2a"><label>2.1.</label><title>Subjects and inclusion and exclusion criteria</title>
<p>In this quasi-experimental study, the main caregivers of premature infants admitted to the NICU of our center from September 2021 to April 2022 were selected as the research objects. The inclusion criteria were: &#x2460; Gestational age of premature infants &#x003C;37 weeks; &#x2461; The weight of premature infants &#x003E;1,800&#x2005;g; &#x2462; The vital signs of premature infants were stable 24&#x2005;h; &#x2463; The primary caregivers of premature infants had clear consciousness and basic ability to care for premature infants and read and understand. Exclusion criteria: &#x2460; Premature infants were transferred to other hospitals for treatment during hospitalization; &#x2461; premature infants who were readmitted; &#x2462; Premature infants&#x0027; family members gave up treatment and asked for signature to be discharged; The study objectives and process were explained to the participants, and anonymity and confidentiality of the information were guaranteed. According to the wishes of the main caregivers of preterm infants, they were divided into group A (FECM group) and group B (non-FECM group) (<xref ref-type="fig" rid="F1">Figure&#x00A0;1</xref>).</p>

<sec id="s2b"><label>2.2.</label><title>Ethical considerations</title>
<p>Before the start of the study, the members of the FECM team explained the purpose, significance, and importance of the research process to the primary caregivers of preterm infants, obtained the support and cooperation of the primary caregivers, and signed the informed consent form.</p>
</sec>
<sec id="s2c"><label>2.3.</label><title>Research methods</title>
<sec id="s2c1"><label>2.3.1.</label><title>Before intervention</title>
<p>A FECM team was established with professional and trained FECM team members to distribute questionnaires to parents and a psychiatrist as a consultant during questionnaire collection. The FECM team consisted of three medical directors (including the psychiatrist), two attending physicians, one chief nurse, three head nurses, three specialist nurses, and three graduate students. Doctors were mainly responsible for explaining the current condition of premature infants and disease-related knowledge, and other personnel was responsible for the formulation, evaluation, and review of health education manuals and family-centered empowerment education programs for main caregivers of premature infants.</p>

<list list-type="">
<list-item>
<p>Step 1: The perceived threat of illness, to assess and improve caregivers&#x0027; knowledge of the severity of illness and the extent to which they felt threatened by the preterm infant&#x0027;s condition. After admission to the rooming-in room, &#x2460; &#x201C;Instructions for Admission to the Ward&#x201D; was distributed to the parents, and ward-related education was carried out. &#x2461; The head of the department and the bedside doctors explained to the main caregivers the current condition of the preterm infants, the problems that need attention, and the potential complications. &#x2462; The main caregivers of premature infants who were admitted to the maternal-infant rooming-in set up a guardian meeting group with 4&#x2013;8 people for 45&#x2013;60&#x2005;min, and the responsible nurses explained and distributed printed brothels, including the nature, etiology, and main clinical manifestations of the disease. &#x2463; The primary nurses accompanied the primary caregivers to fill in the relevant questionnaires and scales. &#x2464; Psychological counseling was given to the main caregivers.</p></list-item>
<list-item>
<p>Step 2: Solve the problem, solve the present, set up a baby refueling class to teach the primary caregivers basic skills to manage the disease and its symptoms, and collect feedback intensively after class. The class time was 45&#x2013;60&#x2005;min, and the feedback was concentrated for 20&#x2005;min after class. Classroom teaching mainly included basic care skills, feeding and nutrition, development support and interaction, observation of symptoms and signs, first aid knowledge, safety precautions, special care, and support outside the hospital. The focused feedback after class mainly included sharing, learning, and later care goals of the main caregivers. After-class focused feedback consisted of assessing the knowledge gained from the previous session by asking the patient 2&#x2013;3 questions. In this step, these issues are addressed through group studies aimed at improving the self-efficacy, self-esteem, and self-control of the students.</p></list-item>
<list-item>
<p>Step 3: Educational participation, through group discussions with 4&#x2013;8 people for 60&#x2013;80&#x2005;min under the guidance of the primary nurse, allows the primary caregiver to face their problems and the problem-solving process, discuss their current situation and what they have done to solve similar problems, At the same time, according to the care ability improvement plan of the main caregivers of premature infants and the feedback of the main caregivers after class, the care level was evaluated, and finally, a practical solution was reached.</p></list-item>
<list-item>
<p>Step 4: Assessment, formative assessment, and summative assessment. The formative assessment aimed to stimulate primary caregivers to internalize their sources of control by understanding their self-empowerment, which emphasizes self-responsibility for the premature infant&#x0027;s health. The effects of the intervention on the caregivers&#x0027; anxiety (GAD-7 scale), readiness for hospital discharge (RHDS-Parent Form), and parenting competence (Preterm Infant Primary Caregiver Assessment of Caregiving Competence Questionnaire) were assessed in a summative manner. The discharge support system was established on the day of discharge, the discharge follow-up group was established, and the WeChat of FECM team members was added to solve the problems of discharged patients in time. Telephone follow-up was conducted 3 days, 1 week, and 1 month after discharge to ask the main caregivers about the current parenting problems and informed the solutions.</p></list-item>

<sec id="s2c2b"><label>2.3.2.2.</label><title>Intervention methods of group B (non-FECM group)</title>
<p>The premature infants were treated and cared for by medical staff throughout the hospital. The main caregivers were discharged according to the routine after receiving the discharge notice, and the responsible nurses informed the relevant precautions of home care. On the day of discharge, they received routine discharge education, distributed education manuals, informed the precautions, and informed the main caregivers to conduct telephone follow-ups 3 days, 1 week, and 1 month after discharge.</p>

<sec id="s2d"><label>2.4.</label><title>Research tools</title>
<p>&#x2460; General information questionnaire: including information on children and main caregivers. The children&#x0027;s information included name, gender, etc., and the main caregivers&#x0027; general information included education level, age, etc. &#x2461; GAD-7: This scale was designed by Spitzer et al. (<xref ref-type="bibr" rid="B10">10</xref>) and other scholars according to the diagnostic criteria of the fourth edition of the American Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). It adopts the 4-level scoring method containing 7 items. The higher the score, the higher the degree of anxiety. &#x2462; RHDS-Parent Form: The RHDS-Parent Form was compiled by Wiess (<xref ref-type="bibr" rid="B11">11</xref>) according to the transition theory of Meleis in 2006, including 5 dimensions and 31 items, including 2 questions and 29 items. &#x2463; The primary caregivers of premature infants&#x0027; care ability assessment questionnaire: the questionnaire was self-designed, was divided into 8 parts, and had a total of 47 items. After the researchers&#x0027; test, Cronbach&#x0027;s <italic>&#x03B1;</italic> coefficient of the questionnaire was 0.97. Eight experts were invited to evaluate the content validity of the questionnaire, and the content validity was 0.95, which showed high reliability and validity, and could be used in clinical research.</p>
</sec>
<sec id="s2e"><label>2.5.</label><title>Statistical analysis</title>
<p>SPSS21.0 software was used for data analysis. The measurement data were described by <inline-formula><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="IM1"><mml:mrow><mml:mover><mml:mi>x</mml:mi><mml:mo stretchy="false">&#x00AF;</mml:mo></mml:mover></mml:mrow><mml:mo>&#x00B1;</mml:mo><mml:mi>S</mml:mi></mml:math></inline-formula> and compared by <italic>t</italic>-test. Enumeration data were described by examples and percentages and compared by the <italic>&#x03C7;</italic><sup>2</sup> test. Ordinal data were described by cases and percentages and compared by a non-parametric test (Kruskal-Wallis <italic>H</italic> test). The anxiety and depression Scale of the main caregivers at discharge from NICU, the discharge readiness scale of the main caregivers at 1 week after discharge from NICU, and the care ability of the main caregivers at 1 week after discharge from NICU were compared between different nursing models. Multivariate linear regression analysis was used for multivariate analysis, with <italic>&#x03B1;&#x2009;</italic>&#x003D;&#x2009;0.05 as the statistical test level. <italic>P</italic>&#x2009;&#x003C;&#x2009;0.05 was considered statistically significant.</p>

<p>In this study, we found that a family-centered empowerment model not only reduced the anxiety level of primary caregivers of preterm infants but also improved the readiness and caregiving capacity of primary caregivers of preterm infants. The overall results can be seen in <xref ref-type="fig" rid="F2">Figure&#x00A0;2</xref>.</p>

<p>FEMC intervention significantly reduced the anxiety of primary caregivers of premature infants: The results of this study showed that there was no significant difference in the scores of primary caregivers between the two groups at baseline (<italic>t</italic>&#x2009;&#x003D;&#x2009;1.660, <italic>P</italic>&#x2009;&#x003E;&#x2009;0.05). Before the intervention, the anxiety scores of primary caregivers in the two groups were higher, and there was no significant difference in the scores between the two groups (<italic>t</italic>&#x2009;&#x003D;&#x2009;0.551, <italic>P</italic>&#x2009;&#x003E;&#x2009;0.05). After the intervention, the score of group A (FECM group) was significantly lower than that of group B (non-FECM group) (<italic>t</italic>&#x2009;&#x003D;&#x2009;&#x2212;2.017, <italic>P</italic>&#x2009;&#x003C;&#x2009;0.05). This indicated that the FECM intervention significantly reduced the anxiety of the primary caregivers. The results of the present study are similar to those of Shahdadi et al. (<xref ref-type="bibr" rid="B12">12</xref>), but while Shahdadi focused on hemodialysis patients, the present study applied FECM to primary caregivers of preterm infants. Through the implementation of FECM, this study changed the traditional way of main caregivers caring for premature infants and encouraged the main caregivers to become the leaders of nursing premature infants. Under the guidance of the FECM group, the main caregivers actively expressed their care needs, and formulated personalized care plans through group discussion, to reduce the psychological burden of the main caregivers and lay the foundation for the smooth discharge of late premature infants. In the process of caring for premature infants, due to the lack of corresponding experience and training, most of the main caregivers are extremely nervous, anxious, and at a loss. FECM intervention can alleviate the anxiety level of most of the main caregivers.</p>
<p>FECM intervention can significantly improve the discharge readiness of primary caregivers of premature infants: The results of this study showed that after the intervention, the total score of discharge readiness in the FECM group was higher than that before the intervention, and the total score of discharge readiness in the control group was lower than that in the intervention group (<italic>t</italic>&#x2009;&#x003D;&#x2009;31.960, <italic>P</italic>&#x2009;&#x003C;&#x2009;0.01). The FECM intervention could significantly improve the discharge readiness of the primary caregivers, indicating that only routine discharge education was given to the primary caregivers at discharge. The personalized home care needs of preterm infants cannot be met, which is similar to the results of Hulya&#x0027;s study (<xref ref-type="bibr" rid="B13">13</xref>). In this study, the FECM group took the care problems of the main caregivers as the starting point, paid attention to the psychological status of the main caregivers and provided peer support through group meetings, informed the main caregivers of feedback on the problems in the care of premature infants in time, and put forward personalized solutions. To provide effective care services to calmly and efficiently deal with the emergency of premature infants, and to improve the coping ability of primary caregivers after discharge. The results of Chen et al. also show that evaluating parents before discharge and helping them to master caregiving skills can facilitate a successful transition from hospital to home care and improve outcomes of preterm infants after discharge (<xref ref-type="bibr" rid="B14">14</xref>).</p>
<p>FECM intervention can significantly improve the care ability of the main caregivers of premature infants: The results of this study showed that there was no significant difference in the care ability of the main caregivers between the two groups before the intervention (<italic>t</italic>&#x2009;&#x003D;&#x2009;&#x2212;0.424, <italic>P</italic>&#x2009;&#x003E;&#x2009;0.05). FECM intervention significantly improved the care ability of the main caregivers (<italic>t</italic>&#x2009;&#x003D;&#x2009;31.960, <italic>P</italic>&#x2009;&#x003C;&#x2009;0.05). This result is similar to that of Masoodi et al. (<xref ref-type="bibr" rid="B15">15</xref>). Unlike Masood&#x0027;s research object, this study applied FECM to primary caregivers of premature infants to improve their comprehensive care ability. Through the training of the FECM group, this study advocates the main caregivers to actively participate in the baby oil classroom, group meetings, bedside skills training, and other projects, to maximize the rights of the main caregivers, cultivate the care skills of the main caregivers, improve the care ability of the main caregivers, and provide a prerequisite for a smooth transition to home care after discharge and improve the quality of life of premature infants. The results are similar to those of Raei et al. (<xref ref-type="bibr" rid="B16">16</xref>). At the same time, primary caregivers are not only providers of care services but also excavators of the potential abilities of preterm infants, which can significantly optimize the health outcomes of preterm infants (<xref ref-type="bibr" rid="B17">17</xref>). Therefore, medical staff should follow the intervention process of FECM to mobilize the enthusiasm of the primary caregivers and encourage them to participate in it, to improve the caring ability of primary caregivers.</p>
<p>However, this study still has some limitations. First, long-term follow-up after the intervention was lacking in this study, and further long-term follow-up can be carried out in the future to verify the long-term effects of FECM. Second, as this study is a single-center study, further multi-center prospective clinical studies are needed to prove the clinical validity of this model. However, our study is also very important clinically. The group meeting has achieved a good response in the implementation process, and peer support by the main caregivers of NICU can be used as an integral part of NICU service in later research.</p>

<p>The application of FECM in premature infants and their main caregivers can significantly reduce the anxiety of the main caregivers, improve the readiness for discharge and care ability, lay a solid foundation for the smooth transition from hospital care to home care, and improve the quality of life of premature infants through the implementation of personalized training, care guidance, and peer support.</p>
