The Needs of Parents of Preterm Infants in Iran and a Comparison With Those in Other Countries: A Systematic Review and Meta-Analysis

Headnote

Abstract

Context: Proper accountability to needs of preterm infants' parents requires recognition of these needs and how they change in different conditions. The aim of this study was to assess the needs of parents of preterm infants in Iran, as compared to those in other regions in the world.

Evidence Acquisition: A search of Iranian databases (Iran Medex, Magiran, and SID) and international resources (PubMed, Scopus, and Google Scholar) was conducted, with no time limitations, to 5 October 2014. Using standard tools, all quantitative studies that considering the parental needs of preterm infants and parental support were extracted. The STROBE checklist was used for the evaluation of the studies. Thirty-one studies were extracted in the qualitative evaluation, of which 17 were included in the metaanalysis. The variance between the studies was analyzed using tau-squared (Tau2) and review manager 5 software.

Results: The results obtained using the nurse-parent support tool (NPST) showed that mothers considered that all the fields of support were of great importance. The parental needs in Iran were similar to those of parents in other regions worldwide. However, the mean score for Iranian parents' assessment of the support they received was 2.20 ± 0.06, whereas it was 3.84 ± 0.72 for other countries. The mean scores for parents' assessment of the provision of emotional, informational appraisal, and instrumental support in Iran were 1.73 ± 0.06,2.1 ± 0.06,1.54 ± 0.6, and 3.44 ± 0.04, respectively, compared to 3.18 ± 1.34,4.11 ± 0.5,4.26 ± 0.18, and 4.51 ± 0.14, respectively, in other countries.

Conclusions: Parents always prefer the priorities of their babies to their individual needs. Given the lower scores for the parental assessment of received support in Iran, it is important to focus on these specific items in providing interventions to meet the needs of Iranian parents.

1.Context

Premature birth is an unexpected event, which can cause parental distress. Depending on the degree of prematurity and the severity of the disease, the infant may have to be hospitalized for a long time in a neonatal unit (1). Concerns about the health and survival of the baby, in addition to the complexity of medical care and technology employed in the neonatal ward, can deeply distress parents (2). In fact, the appearance and behavioral response of the infant causes stress in parents; besides, the experience of developmental challenges of parental role increase their stress because their baby is taken care by the medical staffs and in a strange environment. At the same time, it is expected that parents support not only their sick baby, but also other family members including other children (3). Feeling of stress and problems of role playing as a normal parent can continue long after the infant has been discharged from the hospital. Longitudinal studies of families with preterm infants have shown that long after the baby's discharge, families were faced with many problems in daily life and in compliance with the ongoing situation (4). Thus, from both medical and social perspectives, it is important to provide the best nursing and medical care, as well as social support for families in the neonatal ward, which should be continued even after discharge (5), and comprehensive care plans should be continued, which cover hospital care, information about baby care, and community-based care, including home visits by med- ical staff, and the development of supportive groups (6).

Despite numerous investigations, the insights gained from research were not sufficient for agents who have dedicated themselves to the establishment of family-centered care, and incompatibility and heterogeneity of understanding the needs of parents still exist (7).

Proper accountability of the needs of preterm infants' parents requires recognition of these needs and how they change in various conditions and regions. In this regard, the classification of needs is a useful tool for planning and providing appropriate interventions.

The aim of this study was to review studies that discussed the needs and supportive requirements in different stages from the perspective of parents of preterm infants in Iran and other regions of the world.

2.Evidence Acquisition

Using standard tools, all quantitative studies that considered the parental needs of preterm infants and parental supports were included in the study. Qualitative and interventional studies were excluded from the study. Two independent researchers selected English and Persian articles from Iranian databases (Iran Medex, Magiran, and SID) and international databases (PubMed, Scopus, and Google Scholar), without time limitations to 5 October 2014. As some of the Iranian databases showed no sensitivity to search operators (AND, OR, NOT), the search was done in the local database only through the keyword premature baby to achieve accurate results. In the search of the international databases, the researchers used the general keywords preterm ORpremature and family OR mother ORfather OR parent to ensure high sensitivity. Resources were investigated by two browsers independently. At the beginning of the study, to identify studies with the inclusion criteria, the researchers reviewed the title and abstracts of the obtained articles. Full-text articles were reviewed, and the required data were extracted. In addition, the reference lists of the selected articles were screened to identify relevant studies. Moreover, for access to certain additional information (exact standard deviation) communicated with some authors.

Figure 1 shows a summary of the selection process. Ten items of the STROBE (strengthening the reporting of observational studies in epidemiology) list were used for evaluating the studies (8). The items were: a precise definition of the need or support, an accurate explanation of the purpose of the study, an explanation of the key components of the study design, a detailed description of the time and location of the study, a detailed description of the inclusion criteria and methods for the selection of the study participants, an explanation of the validity and reliability of the instruments, attention to sources of bias and insufficient numbers of samples, attention to limitations of the study, and the possible generalization of the study.

Two independent researchers were responsible for all stages of the evaluation of the articles. In cases of disagreement between the two researchers, an article was judged by a third researcher. Table 1 presents a summary of the extracted data and properties of the studies, Figures 2 and 3 display the assessment related to the quality of studies.

Review Manager 5 software was used for the data analysis (9). Statistical heterogeneity was investigated using the chi-square test at a significance level of 5% (P < 0.05). Lack of consistency between studies was examined using I2 statistics (10). The variance between studies was estimated using tau-squared (Tau2) (11). A meta-analysis was done to capture summary of amount of support and needs. The data were reviewed, and the results were analyzed using a random-effect model and a 95% confidence interval (CI) (12).

3.Results

Thirty-one studies were included in the qualitative evaluation, among which 17 studies were selected for the meta-analysis according to the study's objectives and inclusion criteria. The nurse-parent support tool (NPST) (3) instrument was used in 11 studies, and the neonatal family needs inventory (NFNI) (13) tool was implemented in seven studies In the remainder, the postpartum support questionnaire (14), critical care maternal needs inventory (7), critical care family needs inventory (15), quality of care from the patient's perspective questionnaire (QPP) (5), five anonymous instruments (16-20), premature labor needs questionnaire (PLNQ) (21), preterm birth learning needs questionnaire (PBLNQ) (22), parenting needs questionnaire (6), and antenatal consultation questionnaire (ACQ) (23) were used. In 31 of the studies in this review, 15 studies included only mothers, 15 studies included both fathers and mothers, and one study focused specifically on the needs of fathers.

3.1.Meta-Analysis Results

Seventeen articles were included in the meta-analysis, and the results were arranged in two fields of support and need, separately. Figures 4-12 present the results that were obtained using the NPST. The NPST questionnaire consisted of 21 items. Answers were ranked based on a 5-point Likert scale, with a score of 1 and 5 indicating minimum and maximum support in different situations, respectively. With regard to ranking support, 1-2.59 denoted a low rate, 2.6-3.59 indicated an intermediate level, and 3.6 - 5 signified a high rate (24).

3.2.The Importance of Different Types of Support

Figures 4 - 7 illustrate the importance of support in different fields from the parents' point of view. As shown, all issues were ranked high (> 3.6), and instrumental, informational, emotional, and appraisal supports were considered important.

Figures 8 -12 show the parents' assessment of the support received. Parents generally evaluated received support to be high (< 3.6). However, regarding their assessment of the different types of support they received, only instrumental support was ranked high. In other areas, the informational, emotional, and appraisal supports were separately rated to be medium (2.6 - 3.59), and the lowest rate related to emotional support. The mean scores for the parents' assessments of the provision of emotional, information, appraisal, and instrumental support in Iran compared to those in other countries were 1.73 ± 0.06 vs. 3.18 ± 1.34, 2.1 ± 0.06 vs. 4.11 ± 0.5,1.54 ± 0.6 vs. 4.26 ± 0.18, and 3.44 ± 0.04 vs. 4.51 ± 0.14.

3.3.Parental Evaluation of Needs

Figures 13 -18 illustrate the parents' evaluation of needs using the NFNI tool (13). The total score for needs in Obeisat's study in Germany was significantly lower than that in the other countries (i.e., Iran, U.S. Brazil, and Lithuania). Thus, the results of Obeisat's study were disregarded when calculating the heterogeneity. When this study was excluded, the heterogeneity decreased from 98% to 88%.

4.Conclusions

4.1. NPST

This tool focuses on four areas of instrumental, emotional, appraisal, and informational-communicational support (3). In the present study, the NPST focused on the importance of the support provided and the actual received support from the perspectives of both the parents and medical staff. With regard to the mothers' perspective, the results showed that all fields of support were ranked as very important. In this regard, instrumental, informational, emotional, and ultimately appraisal supports achieved some degrees of importance, respectively. In Iran, compared with other regions (i.e., the U.S. and Hong Kong), all the fields of support, except information, received lower scores. This field was close to instrumental support and was located on the top. Despite the importance that parents considered for different aspects of support, they were not satisfied with various fields of support, except with instrumental support. The received supports in other aspects were assessed as intermediate, with emotional support being considered as the most neglected field. In Iran, other than instrumental support, which was evaluated as medium, the received supports in other parts got a low score. The scores for received support in Iran were much lower than those in other countries (i.e., Italy, the U.S., Australia, and the Netherlands). When the results of the Iranian studies were disregarded, and the heterogeneity was calculated, the I2 scale decreased from 100% to 82%.

4.2. Instrumental Support

This type of support refers to any action specifically associated with infant care (25,26). Interestingly, both in rating fields and in rating the amount of received supports, instrumental support was located in highest point of importance. In fact, parents' stress reduce when they feel their babies received skilled care (27). Although nurses and other health team members provided highly specialized care for premature infants, many mothers were engaged with their maternal role restrictions. Unfortunately, severe conflicts have been reported between parents and nurses that often were due to deterrent actions of nurses in order to marginalize parents and keep their role and authority as experts (28). Mothers were aware of the imbalance of power (29). Although they tended to be involved in their infant's care, they also accepted the nurses' role in facilitating and supporting the development of the parental role (7,13, 25, 26). The findings indicate that the health team should have knowledge of their duties and have positive, open, and reliable communication with parents, without any judgment. Practical standard should indicate the health team's commitment to support open communication with parents in an effort to help parents reduce their anxiety, and staff training should be based on establishing positive relationships and supporting family-centered care (30).

4.3.Informational-Communicational Support

This type of support focuses on providing information regarding the infant's disease, treatment, care, and development needs, in addition to emotional and behavioral responses and parental rights and responsibilities during hospitalization. In the current study, informationalcommunicational support was ranked as the second most important type of support. Research has shown that the provision of continuous and appropriate information to parents about the condition of their infant helps to ensure that the parents become more active partners in taking care of their infants (26).

4.4. Emotional Support

Emotional support includes listening to the feelings and concerns of parents, showing concern about the health of the parents, as well as that of the infant, and taking practical measures to protect them and help them cope with the impact of disease and other aspects of the infant's life (31-33). The third area of support that parents sought was emotional support, although it was located in the lowest step in terms of received supports, and from the parents' viewpoint, the highest gap between claimed and received support related to this field, especially in Iran.

4.5. Appraisal Support

This field is defined as reinforcement for parental role and is the next field of support that parents would have focused on. The identity-oriented performance of the medical team that leads to both empathy with parents and respect of their dignity, involves them in the process of caring for their baby, and promotes the medical-technical capabilities of caregivers, creates a socio-cultural atmosphere, which can strengthen the confidence of parents in taking parental roles (5). To fill the gap between the perceived and received support, the health team should be encouraged to consider whether the type and amount of support provided are in accordance with the needs and views of parents. Adopting various family-centered strategies, such as family centered rounds and facilitating the participation of parents in decision making, can be effective in reducing this gap (25,34).

4.6. NFNI

This tool focuses on the needs in five areas: assurance, proximity, awareness, support, and comfort (13). Average scores given for each field of needs, with scores higher than the average indicating the perceived importance of each area. In the present study, generally, the parents believed that needs within the field of assurance were the most important issues the fulfillment of which can persuade parents to continue their infant's admission in NICU. After this issue, awareness, proximity, support, and finally comfort were located, respectively.

4.7. Assurance

The assurance item was ranked as most important, as infants' parents are exposed to fear, anxiety, and uncertainty about the fate and future health of their infant in the NICU. It can be implied that the need for being heartened about the survival of the baby was the first priority. Hence, the expression of reciprocal empathy and concern by staff, as well as the use of inspiring and encouraging words along with care, can be very valuable (3 ).

4.8. Support

The parents ranked the need for support as low. This may be associated with the lack of parental support programs in the NICU where the included studies were conducted. Not having an opportunity to experience the potential benefits of participation in family support groups may affect the priority of needs from the parents' perspective (35).

4.9. Comfort

Parents ranked the importance of personal comfort as lowest, as their main concern was for their infant (7,15).

4.10. Proximity

The need to be close to the infant and have physical contact with him/her is important for parents. In Iran, the need for proximity was placed in the first priority. This may be due to the lack of open-door policies and unrestricted presence (36). Parents were so concerned about dangerous situations, such as incorrect care, inadequate attention to the baby, and unskilled care (29).

Special care of parents: There were correlations between maternal and neonatal characteristics and the needs of mothers (35,37). The results showed that the availability of support programs for parents in the NICU are increasingly being taken into consideration. A special nurse as an interface in neonatal ward and maternal and child health units has been evaluated positively by both fathers and mothers (38,39). Planning for the activation of outpatient resources at national and local levels, with a focus on creating environments that present the integrated medical care, upgrading the provision of comprehensive familycentered community-based services, and providing tips for parents to access these centers seem necessary (40).

4.11. Conclusion

In general, it can be concluded that the parents prioritized the needs of the infant over their individual needs. To improve services for parents, the needs of both parents and infants should be considered. Frequent and periodic health assessments should be undertaken to determine whether the type and level of support provided are in line with the needs and views of parents. Given the lower scores assigned by Iranian parents in their assessments of the received support, it is important to focus on these specific items in providing interventions to meet parental needs of preterm infants.
