Introduction
Preterm infants refer to live babies born before 37 weeks of gestational age, which are born ahead of time due to internal and external factors (1). It has been documented that approximately 15 million infants are born preterm globally each year, with an estimated 1.2 million of these births occurring annually in China. This figure is noted to be on the rise, with an increasing trend observed year over year (2,3). The organs of preterm infants are not yet mature, and the incidence of complicated disease is higher than that of full-term infants (4). Most preterm infants are sent to neonatal intensive care unit (NICU) for treatment after birth. Due to incomplete development and limited thermogenic system, the body temperature of preterm infants is unstable and difficult to regulate, and the resistance to various infections is very weak, preterm infants are often accompanied by complications (5,6). With the substantial increase in the survival rate of preterm infants, how to improve the quality of life of preterm infants has become the focus of social attention (7). At present, NICU is still in closed management around the world, ignoring the positive role of the family, resulting in the separation of mother and baby, limiting the physical and emotional interaction between parents and infants, parents have only a little time to visit and accompany the infants, and some parents often find it difficult to fulfill reasonable parenting behavior after the infant being discharged from hospital, which can easily lead to negative emotions such as anxiety and depression (8,9).
Many previous studies (10-12) have shown that parental care plays an important role in the growth and development of preterm infants. Family-integrated care represents an innovative nursing paradigm that fosters parental involvement in the pediatric care process under the supervision of healthcare professionals. This model aims to cultivate a cohesive and supportive healthcare setting that is conducive to the well-being of children (13,14). Family integrated care model is a new nursing method, which emphasizes the important role of parents in the growth and development of preterm infants, and forms a treatment system among medical staff, parents and preterm infants (15). After professional education and training, the parents may participate in all kinds of non-medical nursing, which can help parents better understand and various physiological and psychological needs of preterm infants (16,17). Several studies have reported the effect of family integrated care model on preterm infants, and the results are different and inconsistent. Therefore, the purpose of this study is to systematically evaluate the effect of family integrated care model on preterm infants to provide scientific basis for improving the nursing quality of preterm infants. We present this article in accordance with the PRISMA reporting checklist (available at https://tp.amegroups.com/article/view/10.21037/tp-24-373/rc).
Methods
Literature inclusion and exclusion criteria
The inclusion criteria of this meta-analysis were as follows: the type of study was a randomized controlled trial (RCT); the study population were preterm infants whose gestational age was less than 37 weeks. The intervention group was treated with family integrated care on the basis of routine nursing of preterm infants, and the control group was treated with routine nursing of preterm infants without family participation. Outcome indicators: breastfeeding rate of preterm infants, weight gain of preterm infants, sleep time of preterm infants and the one-month readmission rate.
The literature exclusion criteria were as follows: repeatedly published literature, cases, reviews, conference papers, and literature reports in which the outcome index could not be extracted after contacting the corresponding authors.
Literature retrieval strategy
The authors searched for published RCTs about the effect of family integrated care pattern on preterm infants. The retrieval databases included PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Weipu and Wanfang databases. The search strategy of this meta-analysis was as follows: (“newborn” OR “infants” OR preterm “OR” preterm infants “OR” preterm “OR” preterm infants “OR” prematurity “OR” neonatal “or” neonatal prematurity”) AND (“family integrated care “OR” FIC “OR” family integrated nursing”) AND (“randomized controlled trial “OR” clinical trial “OR” RCT”). The time limit for retrieval was from the establishment of the database to August 25, 2024. The search languages were limited to Chinese and English.
Literature screen and data extraction
After browsing all the titles and abstracts of the literature retrieved by the two authors, the obviously irrelevant studies were excluded. Then we read the full text of the relevant literature and screened the literature according to the inclusion and exclusion criteria. In the event of a dispute, the third author would assist in evaluating the matter, and a consensus would be reached through discussion. After reading the full text, the research data including characteristics of study population, details of intervention measures and outcomes were extracted.
The quality evaluation of included RCTs
Two researchers used the Cochrane bias risk tool to assess the bias risk of included RCTs: whether it was RCT, randomized concealment, blind trial intervention and outcome evaluation, incomplete outcome data processing, selective reporting, risk of early termination of the trial, whether the baseline was balanced between the trial group and the control group, and whether there was bias from sponsors. Each evaluation content could be evaluated as low-risk, high-risk or unclear.
Statistical analysis
We used RevMan5.3 software for meta-analysis. For the results of binary variables, it was expressed by odds ratio (OR) and 95% confidence interval (95% CI), and for continuous variables, it was expressed by mean difference (MD) and 95% CI. The heterogeneity among the included studies were tested by I2 test. If I2>50% suggested a high degree of heterogeneity, a random effect model was used. If I2 was less than 50%, there was no significant heterogeneity between studies, and a fixed effect model was used. Funnel chart and Egger regression analysis were used to analyze the publication bias of the study. When P<0.05, the difference was statistically significant.
Results
Study selection
Initially, a comprehensive search yielded a total of 620 articles. After rigorous screening, 565 articles were excluded due to non-adherence to the inclusion criteria or duplication. This process left us with 55 full-text articles for further review. Upon closer examination, an additional 42 articles were deemed ineligible based on the predefined criteria. Finally, 13 RCTs (18-30) were included for meta-analysis (Figure 1).
Characteristics of included RCTs
As shown in Table 1, of the included 13 RCTs (18-30), a total of 3,005 preterm infants were involved, 1,390 preterm infants received family integrated care, and 1,615 preterm infants received routine nursing care. After training, the family members could take care of the preterm infants together with the medical staff, and the family members could participate in non-medical nursing operations.

Quality of included RCTs
As presented in Figures 2,3, the overall quality of the 13 RCTs was good. All the RCTs mentioned the method of generating random sequences, and only 4 RCTs introduced the allocation hiding method. The double-blind method was not introduced in detail in the included literature. All the included RCTs compared the baseline data of gestational age and birth weight between the intervention group and the control group, and the baseline data of the two groups were comparable.
Meta-analysis
Eight RCTs reported the effect of family integrated care on the breastfeeding rate of preterm infants. There was significant statistical heterogeneity among the studies (I2=92%, P<0.001). Random effect model analysis was selected for meta-analysis. The results showed that family integrated care could increase the breastfeeding rate of preterm infants (OR =5.92, 95% CI: 2.37, 14.82, P<0.001, Figure 4A).
Nine RCTs reported the effect of family integrated care on the weight gain of preterm infants. There was significant statistical heterogeneity among the studies (I2=80%, P<0.001). Random effect model analysis was selected for meta-analysis. The results showed that family integrated care could increase the weight gain of preterm infants (MD =3.16, 95% CI: 2.51, 3.80, P<0.001, Figure 4B).
Two RCTs reported the effect of family integrated care on the sleep time of preterm infants. There was no significant statistical heterogeneity among the studies (I2=0%, P=0.81). Fixed effect model analysis was selected for meta-analysis. The results showed that family integrated care could increase the sleep time of preterm infants (MD =3.25, 95% CI: 2.05, 4.44, P<0.001, Figure 5A).
Five RCTs reported the effect of family integrated care on the one-month readmission rates of preterm infants. There was no significant statistical heterogeneity among the studies (I2=0%, P=0.55). Fixed effect model analysis was selected for meta-analysis. The results showed that family integrated care could reduce the one-month readmission rates of preterm infants (OR =0.37, 95% CI: 0.22, 0.61, P<0.001, Figure 5B).
Sensitivity analysis
In order to test the source of heterogeneity and the reliability of the combined results, a new meta-analysis was carried out by removing a study one by one, and the new combined effect and its heterogeneity were not significantly different from those before removal, indicating that the results of this meta-analysis were reliable.
Publication bias
We used the funnel chart (Figure 6) to evaluate the publication bias of the literature, the dots in the funnel plots were basically symmetrical, suggesting that the publication bias was small. The results of Egger regression test indicated that there was no publication bias amongst the synthesized outcomes (all P>0.05).
Discussion
Family integrated care is based on the humanistic neonatal nursing model of Aishataria, which refers to a nursing mode that allows parents to participate in non-medical routine life care during hospitalization on the premise of education and guidance by neonatal specialist nurses (31). With the development of neonatal science, the original NICU closed management model can no longer meet the needs of preterm infants for the establishment of parent-child relationship during hospitalization and the requirements of parental care ability after the disease is cured and the infants return to the family (32,33). There is an urgent need for nurses to actively develop innovative consciousness and make reforms on the basis of the existing NICU closed management system to support parents of preterm infants to participate in the care of preterm infants directly at NICU (34). This model of involving family members in medical treatment and nursing decision-making of preterm infants is an important breakthrough and will be the development direction of neonatal nursing. The results of this meta-analysis have found that family integrated care is beneficial to improve the breastfeeding rate and weight gain of preterm infants, increase the sleep time of preterm infants and reduce the one-month readmission rates of preterm infants. With more RCTs included, our findings are consistent with previous report (35). Family integrated care should be promoted in clinical nursing care.
The traditional NICU implements closed management, and the separation of parents and infant makes the family relationship between parents and infant unsatisfied (36). On the one hand, it has a great impact on the parents’ psychology, increasing the mother’s negative emotions such as anxiety and depression, on the other hand, breastfeeding is difficult to be guaranteed (37). Previous studies (38,39) have shown that the breastfeeding rate of NICU preterm infants during hospitalization is less than 45%. Furthermore, the sleep patterns of preterm infants in the NICU are susceptible to disruption by factors such as lighting, noise, and medical interventions, which can potentially result in sleep disturbances (40,41). Family integrated care model emphasizes the role of family members to preterm infants, through a series of measures to make family members participate in the nursing of preterm infants in hospital, including feeding, touching, changing diapers, wiping bath and other life care, so as to promote the development of preterm infants to obtain professional care and sufficient emotional needs. Sleep is very important for newborns (42,43). During sleep, the secretion of growth hormone in preterm infants increases, their weight and height develop rapidly, and their meridian system continues to develop for a long time after birth, these processes are inseparable from good sleep (44). The findings of this study demonstrate that the implementation of a family-integrated care model significantly enhances the sleep duration of preterm infants, which is instrumental in promoting their developmental and growth trajectories. Within this model, parents of preterm infants are actively engaged in their children’s care, receiving professional guidance from healthcare providers. This enables them to acquire a deeper understanding of nursing knowledge and skills, facilitating the continuity of care post-discharge and potentially reducing the readmission rates of preterm infants (45).
It is a great challenge for medical staff to include parents in NICU to work with medical staff. Medical staff should focus on providing psychological support and help to parents and inform them of the significance, purpose and benefits of the family integrated care project (46,47). When the vital signs of preterm infants are stable, it is imperative to focus on the education and training of parents in care knowledge and skills. Concurrently, it is essential to address and refine the perceptions and awareness of medical and nursing staff. This involves bolstering the humanistic consciousness and literacy among healthcare providers and ensuring they offer robust psychological support to the parents of preterm infants. While prioritizing the treatment of preterm infants’ medical conditions, healthcare professionals must also be attentive to the emotional well-being and educational needs of the parents, to foster a comprehensive and supportive care environment (48). The cultivation of long-term care ability such as parental care and late rehabilitation of preterm infants after returning to home should also be considered and trained (49). Family integrated care model plays a positive role in promoting sleep and development of preterm infants, it is worth further popularizing and applying in clinical care.
There are some limitations in this meta-analysis. First of all, the number of included literatures is limited, and the research reports are mainly from China and Canada, which may have regional and demographic deviations. Secondly, the inclusion of RCTs has some deficiencies in the setting of blind method. Finally, the intervention methods and contents of the included studies are different, there are also some differences in the included sample size and specific evaluation indicators. In the future, large samples, multi-center, strict design and high-quality RCTs are needed to analyze the role of family integrated care.
Conclusions
In conclusion, with 13 RCTs included, this meta-analysis has found that family integrated care is helpful to improve the breastfeeding rate, weight gain of preterm infants, increase the sleep time of preterm infants and reduce the one-month readmission rates of preterm infants. At present, more and more nursing models emphasize parents’ participation in hospitalized care of preterm infants. The concept of family-centered care requires medical managers to actively develop innovative consciousness and change the traditional concept of closed management of NICU. On the foundation of ensuring thorough family training and effective supervision, the family-integrated care model should be integrated into the NICU to enhance the prognosis of preterm infants.
