Parents’ ratings of post-discharge healthcare for their children born very preterm and their suggestions for improvement: a European cohort study

Follow-up of very preterm infants is essential for reducing risks of health and developmental problems and relies on parental engagement. We investigated parents’ perceptions of post-discharge healthcare for their children born very preterm in a European multi-country cohort study. Data come from a 5-year follow-up of an area-based cohort of births <32 weeks’ gestation in 19 regions from 11 European countries. Perinatal data were collected from medical records and 5-year data from parent-report questionnaires. Parents rated post-discharge care related to their children’s preterm birth (poor/fair/good/excellent) and provided free-text suggestions for improvements. We analyzed sociodemographic and medical factors associated with poor/fair ratings, using inverse probability weights to adjust for attrition bias, and assessed free-text responses using thematic analysis. Questionnaires were returned for 3635 children (53.8% response rate). Care was rated as poor/fair for 14.2% [from 6.1% (France) to 31.6% (Denmark)]; rates were higher when children had health or developmental problems (e.g. cerebral palsy (34.4%) or epilepsy (36.9%)). From 971 responses, 4 themes and 25 subthemes concerning care improvement were identified. Parents’ experiences provide guidance for improving very preterm children’s post-discharge care; this is a priority for children with health and developmental problems as parental dissatisfaction was high. In a European population-based very preterm birth cohort, parents rated post-discharge healthcare as poor or fair for 14.2% of children, with a wide variation (6.1–31.6%) between countries. Dissatisfaction was reported in over one-third of cases when children had health or developmental difficulties, such as epilepsy or cerebral palsy. Parents’ free-text suggestions for improving preterm-related post-discharge healthcare were similar across countries; these focused primarily on better communication with parents and better coordination of care. Parents’ lived experiences are a valuable resource for understanding where care improvements are needed and should be included in future research.

INTRODUCTION
Very preterm births (<32 weeks of gestation) represent up to 1.6% of births in high-income countries 1 or up to 2% of births worldwide. 2 Although survival for these infants has improved, they remain at increased risk of developing multiple health and developmental problems compared to infants born at term. 3,4 As the prognosis for each individual infant is unknown at discharge from hospital, follow-up is essential for the early identification of health needs, the coordination of health services from multiple providers, and for enabling timely intervention. 5 Parents' engagement is crucial for successful follow-up of preterm infants, 6 but few studies have reported on parents' own evaluations of the post-discharge care offered to their children. Parents may provide important insights for improving healthcare beyond aspects of medical, outcome-related quality, 7,8 and this knowledge may help to improve service adherence, care delivery, 8 and consequently health outcomes. Qualitative studies involving parents have suggested that there is room for improvement in the continuity of care for preterm infants 9 and that assistance with accessing services or providing comprehensive information to parents may impact on the use of post-discharge services in this population. 10 The use of early intervention services has been shown to improve outcomes in both children 11 and parents 12 and may be of most benefit to socially deprived families. 13 At the same time, unfavorable social factors such as poorer financial resources 14 or lower educational level 15 have been associated with multiple barriers for attending follow-up services 14 and follow-up discontinuation 15 for children at risk of developmental problems and morbidities.
Although parents are frequently involved in evaluating specific healthcare services or units, 16,17 pediatric specialties, 18 or aspects of care, 9 there have been no large-scale or international evaluations of post-discharge care involving parents of children born very preterm. The main aims of this study were to assess parents' ratings of their children's prematurity-related care from discharge from neonatal care until 5 years of age in a large cohort from 19 regions in 11 European countries by sociodemographic characteristics and child health outcomes. In addition, we aimed to provide a thematic synthesis of parents' suggestions on how healthcare can be improved.

Data sources
The data were collected for the Screening to improve Health In very Preterm infantS (SHIPS) study, which followed up the areabased EPICE cohort of infants born before 32 weeks' gestation over 12 months in 2011-2012, 19,20 in all maternity units of 19 regions in 11 European countries: Belgium (Flanders); Denmark (Eastern region); Estonia (entire country); France (Burgundy, Ile-de-France, and Northern regions, 6 months' data collection only); Germany (Hesse and Saarland); Italy (Emilia-Romagna, Lazio, and Marche); the Netherlands (Central and Eastern regions), Poland (Wielkopolska); Portugal (Lisbon and Northern regions); Sweden (greater Stockholm); and the United Kingdom (East Midlands, Northern, and Yorkshire and the Humber regions). Children were followed up at 2 and 5 years of age using parental questionnaires. At 5 years of age, a subset of all children born before 28 weeks' gestation were also invited to participate in clinical assessments. 19 Ethics Ethics approvals and parental consent were obtained according to national legislation in each country before data collection. The SHIPS project was approved by the French Advisory Committee on Use of Health Data in Medical Research and the French National Commission for Data Protection and Liberties.
Study population At baseline, the cohort included 7900 live births and 2429 stillbirths and terminations of pregnancies. Six thousand seven hundred and ninety-two infants were discharged alive from the neonatal unit ( Supplementary Fig. S1 (online)). At 5 years, 6759 children were alive, of whom parents of 3687 (54.5%) children participated in the followup and 3635 (53.8%) returned a questionnaire. 19 Data collection At inclusion, pregnancy and perinatal data were collected from obstetric and neonatal records. At 5 years of age, health, healthcare, and socioeconomic information was collected using parent-report questionnaires that had been pre-tested in all national languages. The questionnaires could be completed at home, in follow-up clinics, online, or using paper questionnaires, depending on local study protocols. Questionnaires could be filled in by mothers, fathers, or other primary caregivers. They were asked the following question: "How would you describe the healthcare your child has received related to his or her preterm birth after being discharged from the neonatal unit; excellent, good, fair, poor, or has not received any healthcare related to very preterm birth?" The parents were also asked to provide suggestions for how healthcare for very preterm children can be improved, as free-text responses.

Data analysis
Proportions of poor-to-fair ratings (considered to represent dissatisfaction) were described by country. The association between dissatisfaction and sociodemographic characteristics and child health was assessed using χ 2 tests. Sociodemographic characteristics included maternal educational level (lower: lower secondary [ISCED levels 0-2], intermediate: upper or postsecondary, non-tertiary or short cycle tertiary [levels [3][4][5], or higher: Bachelor degree or higher [levels [6][7][8]), 21 country of birth (native-born, born elsewhere in Europe, or born outside Europe), family situation (mother living with partner vs. single caregiver or other family situation), age at delivery (≤24, 25-34, or ≥35 years), parity at delivery (multiparous vs. nulliparous), and multiplicity (singleton vs. twins or more). As in previous analyses of this cohort, perinatal risk factors were used to create a variable representing overall risk of health and developmental problems at discharge from the neonatal hospitalization, classified as: lower (born over 29 weeks' gestation, not small for gestational age [SGA; birth weight <10th centile for intrauterine norms for gestational age and sex, using references developed for the cohort 22 ] and without severe neonatal morbidities [bronchopulmonary dysplasia (BPD), i.e., need for supplemental oxygen or ventilation at 36 weeks' postmenstrual age, stages III-V retinopathy of prematurity (ROP), levels III-IV intraventricular hemorrhage (IVH), cystic periventricular leukomalacia (cPVL), or necrotizing enterocolitis (NEC) needing surgery] or congenital anomalies [CA]), moderate (not classified as higher or lower risk), or higher risk (born below 28 weeks' gestation or at least one neonatal morbidity or a severe CA). 23 Data on the child's health at 5 years included a parental rating of their child's overall health status (good/excellent vs. poor/fair) and asthma diagnosis. Data on developmental and neurosensory difficulties included the parent's rating of their child's development (average/advanced vs. delayed/very delayed); clinical diagnosis of cerebral palsy, epilepsy, and autism; and reports of moderate or severe vision or hearing problems (defined as having difficulties seeing even with glasses, being blind or seeing light only, requiring hearing aids, or being deaf).
To obtain adjusted risk ratios for dissatisfaction with healthcare services, we used three multilevel generalized linear regression models with a log link, Poisson distribution, and a robust variance estimator, 24 with two levels to account for correlation between siblings: one including sociodemographic variables and country only, and two adding either parent-rated health and developmental problems or diagnosed developmental or neurosensory difficulties. We did not run a model with all variables due to collinearity between parent-reported health status and clinical diagnoses. The covariates were selected based on the scientific literature and bivariate analyses, including variables that were related to parental ratings with a p value <0.2. We used the sample average as the reference for presenting the country risk ratios for poor/fair ratings. In sensitivity analyses, regression models were (1) adjusted for all covariates without selection based on a p value cut-off and (2) restricted to cases where the questionnaire was answered by mothers only.
Non-response and missing data The response rate varied depending on the country (53.8% overall, range 29.3-96.4%); non-responders in the cohort were more likely to be younger, foreign-born mothers, and have a lower educational level, as detailed elsewhere. 19 To take into consideration potential attrition bias, we generated inverse probability weights based on characteristics of non-responders available at baseline and at the 2year follow-up, after multiple imputation of missing values, 25 following methods previously used in this cohort. 26 This approach gives a higher weight to children with characteristics that are underrepresented because of non-response. First, 20 imputations using multiple chained equations were performed to impute missing values for the variables used for predicting the inverse probability weights. Data were assumed to be missing at random. All variables associated with loss to follow-up were included in the regression: gestational age in completed weeks, Apgar score (<7), use of continuous positive airway pressure, use of mechanical ventilation, use of prophylactic surfactant within 2 h after birth, birth in level 3 unit, inborn status (no transfer within 48 h of birth), SGA, any CA (severe or non-severe vs. none), BPD, any severe morbidity at discharge (IVH, cPVL, ROP, or NEC), surgery (for patent ductus arteriosus, CA, NEC, or other reasons), infant received human milk at discharge, mode of delivery (vaginal/instrumental vs. cesarean), previous cesarean section, parity at delivery, antepartum hemorrhage after week 20, premature rupture of membranes (>12 h), multiplicity, mother's age at delivery, mother's country of birth, mother's educational level, gross motor impairment at 2 years corrected age, 27 cognitive delay at 2 years corrected age, 27 and study region. The weights were estimated on the total sample of infants eligible for follow-up at 5 years. All proportions in the tables are derived from the weighted sample and all models were run with weights. In sensitivity analyses, we ran models truncating weight values at the 95th percentile to assess whether the results were affected by the extremes of the weight distribution.
Missing data were not frequent among responders: 2.7% of healthcare ratings were missing and the proportion of missing data varied between 0.3% (maternal age) and 5.3% (country of origin) for co-variables.

Analysis of free-text responses
Free-text responses were explored using thematic analysis. We used an iterative process for the translation of responses and initial coding into keywords and subthemes. The approximately 1300 freetext responses were first automatically translated using Google Translate. Tables including the original juxtaposed with the automatically translated text were used for a first coding of keywords and preliminary themes by the first author. In this step, specific ambiguities in the translations or where multiple interpretations were possible were highlighted. These tables were then sent to the country teams who reviewed the translations and key words. The focus of this step was to ensure that the text was correctly translated and that these translations, as well as the keywords, reflected the original content. As it was not possible to return questionnaires to the responders for clarifications, responses that could not be interpreted after review, due to poor wording or lack of detail, were removed. After this step, keywords were coded into themes and subthemes by the first author, which were reviewed and validated by a qualitative researcher (P.S.); a random sample of the responses were double-coded by P.S. and divergences were discussed with the first author until consensus was reached. Responses that contained more than one suggestion were coded into several themes and duplicate responses for multiple siblings were removed. Themes and subthemes were summarized and described by country and healthcare ratings. Citations were extracted to illustrate the most common subthemes, while ensuring the confidentiality of the responder. The citations selected for presentation in the manuscript were reviewed again by country team members to ensure the precision of the translation.
All data analyses were carried out with STATA 14.0 (Stata Corp., College Station, TX, USA) and Excel 2013.

RESULTS
Questionnaires were returned for 3635 children; by mothers (83%), fathers (15%), and other caretakers, such as grandparents (1.4%), all hereafter referred to as parents. Parents reported that 92.8% of the children had received post-discharge care for their prematurity.
For 14.2% of these children, parents judged the care to be poor or fair, but this varied from 6.1% in France to 31.6% in Denmark. (Table 1). Parents expressed more dissatisfaction with postdischarge care when maternal educational level was higher and when mothers were native-born or born outside Europe compared to mothers born elsewhere in Europe ( Table 2). Proportions of poor/fair ratings were higher for children with parent-rated health or developmental problems, diagnosed cerebral palsy or epilepsy, or moderate-to-severe vision or hearing problem at 5 years of age. Table 1. Parents' ratings of preterm birth-related healthcare by country, ordered by weighted proportion of poor or fair ratings.
How would you describe the healthcare your child has received related to his or her preterm birth, after being discharged from the neonatal unit? Higher maternal educational level, being native-born, and child health and developmental difficulties remained associated with poor/fair ratings in the adjusted analyses (Table 3). Significant differences in risk ratios persisted across countries after adjustment, despite slight changes in point estimates. Incorporating remaining covariates (mother's age, parity, multiple birth, and asthma diagnosis, p value >0.2) in our sensitivity analysis did not change these associations (data not shown). Sensitivity analysis with only mothers as responders showed slightly higher rates of dissatisfaction (15.0% instead of 14.2%) but did not change the results from the main models (data not shown). Differences between weighted and unweighted proportions of poor and fair ratings were minimal: 13.5% [95% confidence interval (CI) 12.3-14.7] vs. 14.2% [95% CI 12.9-15.6] overall (see Supplementary  Table S1 (online) for unweighted proportions by country) and associations with other co-variables in unweighted and weighted models were similar (Supplementary Table S2 (online)) but slightly increased in the association between mother's educational level and dissatisfaction as well as perinatal health and dissatisfaction. Sensitivity analyses truncating weights at the 95th percentile (n = 52 at weight = 4.24) did not affect results. See Supplementary  Table S2 (online) for models (Model III) with and without truncated weights, compared to unweighted models.
Parents provided 1105 (30%) unique free-text responses, of which 85 stated "no comment" or "do not know" and 49 that the child had not received post-discharge care. The remaining 971 responses were analyzed thematically. Some themes did not relate to improvements in post-discharge healthcare but focused on positive experiences with healthcare (n = 232 suggestions) or care during the neonatal hospitalization (n = 137 suggestions) and were excluded. Four themes and 25 subthemes were related to healthcare improvements, as shown in Table 4. Among the parents who provided free-text responses, 956 also rated the postdischarge care; 25.7% (n = 246) rated the care as poor or fair and 74.3% (n = 710) as good or excellent (not shown).
The most frequent theme was (I) Coordination of follow-up and healthcare, with Improving care coordination as the most common subtheme. Parents reported a lack of coordination, having to take responsibility for the organization of healthcare and identification of the appropriate healthcare providers for their child, which was described as an exhausting, stressful, time consuming, or difficult task. Some parents experienced having numerous appointments with poor continuity of care and lack of communication between multiple healthcare providers or asked for a reference person to coordinate care or follow-up.
"Big disappointment that no one has overall responsibility for follow-up. Our daughter has many doctor visits at three different hospitals. Countless visits could have been avoided if someone had an overview of the situation." -Parent, Sweden (care rating: Poor) Other reoccurring subthemes in this category included the need for further training of generalists and nurses (especially health visitors and Child Healthcare Centre nurses) on preterm birth, having more equitable access to follow-up and services, and reducing waiting times on waiting lists, especially for visits to specialists, and queuing in the waiting rooms.
"After finishing the follow-up at the neonatal unit, we find that both the Child Healthcare Centre nurse and the preschool lack knowledge of premature babies and their needs. Thus, more knowledge/education to Child Health Centre and preschool staff." -Parent, Sweden (care rating: Excellent) "Unfortunately, help for premature babies is only available in larger cities. We live in the countryside and have limited access to all specialists. A visit to a specialist is associated with an additional trip, and I do not always have a transport and unfortunately there is still a very long waiting time for some specialists." -Parent, Poland (care rating: Good) The second most frequent theme was (II) Follow-up type and content. Two common suggestions included having more frequent or longer follow-up. The reasons included reassuring parents that the child was reaching important developmental milestones, to know whether the child was ready for school and/or needed school support. A few parents felt that follow-up was unnecessary when their child was doing well.
"There should be a follow-up when the children reach school age to see how they are developing and whether they are ready to go to school." -Parent, Denmark (care rating: Fair) Improving follow-up with additional examinations or therapies, especially before school start, and following up on other areas apart from physical health, such as emotional and mental health, were two frequent subthemes in this category.
"Preterm children could have a check every year, especially hearing, vision and psychologist. There should definitely be a check before school." -Parent, Estonia (care rating: Good) "Follow-up on physical health was fine. Follow-up on mental health and "invisible" late effects were non-existent. We were all alone with those things and ended up seeking help from a private consultant." -Parent, Denmark (care rating: Poor) Improving healthcare professionals' communication with parents, in category (III) Communication and parent support, was the most All risk ratios are derived from weighted, multilevel generalized linear regression models, accounting for correlation between siblings.
Parents' ratings of post-discharge healthcare for their children born. . . A.-V. Seppänen et al. frequent subtheme overall. Main issues were lack of communication from healthcare providers and lack of information sharing with parents regarding medical procedures, follow-up and medical services available, how to care for a child born very preterm, and what to expect regarding the child's long-term health or schooling. Some suggestions concerned interpersonal aspects, such as lack of empathy or listening, or requesting a more humane or positive attitude from healthcare providers.
"It was explained in the neonatal unit that in the future we may come across problems such as learning difficulties, vision, hearing, developmental delay. However, it was never explained if and what services would help overcome any of these problems." -Parent, UK (care rating: Poor) Parents also frequently suggested psychological or emotional support for the parents themselves as part of the long-term followup after discharge. They expressed a feeling of being left alone to cope with the trauma of very preterm birth and the burden of taking care of their child after discharge, without sufficient psychological support for both parents.
"I, as a mother, would have wished for better support after discharge. After the hospital stay, you are left alone with your worries and fears". -Parent, Germany (care rating: Excellent) "Making room for parents too, because also the motherhood was premature." -Parent, Italy (care rating: Fair) Subthemes were similar across countries (not shown) and similarly ranked for parents who rated the healthcare as poor or fair and those who rated healthcare as good or excellent.

DISCUSSION
Overall, 14.2% of the children in our study received healthcare that their parents rated as poor or fair, with variation between 6.1% and 31.6% by country. However, dissatisfaction was significantly higher for children with health or developmental problems; up to over one-third when children had a diagnosis of cerebral palsy or epilepsy or when parents rated their children's health as poor or fair. Dissatisfaction with post-discharge care was more frequent among mothers with higher educational status. Thematic analysis Table 4.

The strengths of this study include its population-based design, geographic diversity, large sample size, and the use of a standardized, pre-tested questionnaire. A strength, but also a limitation, of the study is the wide definition of post-discharge healthcare covering the period between neonatal intensive care unit (NICU) discharge and 5 years of age. As follow-up programs and health services vary across countries in terms of availability, content, and duration, our questionnaire intentionally referred to a large range of services over a long period of time. Thus we are able to measure overall perceptions with how very preterm birth is managed in the long term across countries, but we cannot know if parents referred to specific care aspects in their ratings (medical quality, screening, interventions etc.), unless parents specified the service or time period in the free-text answers. The free-text question intentionally leads parents toward more negative experiences, as it focused on aspects requiring improvement in care. However, the long time period may lead parents to refer care ratings either to more recent care or care related to more difficult and stressful experiences, which may have happened around NICU discharge and in early childhood when medical follow-up is more intense. In the latter case, the ratings may be more negative than if the question had covered a more proximate period. Unfortunately, we did not have data on the characteristics of services received nor objective measures of the quality of services, such as waiting times or service availability, to contrast with parental perceptions. Another potential limitation relates to the multilingual nature of our sample, in particular when interpreting the free-text responses. When translation is part of the research process, it inevitably involves a degree of interpretation 28 and may increase the risk of misinterpretation of answers. 29 To minimize this risk, we used an iterative process for the translation and interpretation using automatic translation, followed by coding of keywords and finally a review of translation accuracy and interpretation by researchers in each of the study countries. A final limitation was the potential for bias linked to non-response, which was 45.5% for the overall sample and higher in some countries. 19 Loss to follow-up is a challenge in longitudinal cohort studies, 30 especially those with population-based designs, and can be related to characteristics that may affect healthcare perceptions. We used inverse probability weights to adjust for attrition bias. Reassuringly, results based on the unweighted and weighted analyses were similar but slightly increased the association between mother's educational level and dissatisfaction as well as perinatal health and dissatisfaction. Previous studies in this cohort have shown that the association between sociodemographic or perinatal factors and health-related outcomes may be accentuated when using these weights, 21 as increased loss to follow-up in socially disadvantaged groups is taken into account.
The proportion of poor/fair ratings varied widely across countries. The study countries differ on several structural aspects that may have contributed to these differences but that we were not able to measure, such as the organization of primary care, 31 level of integrated care in the case of multi-morbidity, 31 patients' ability to pay for out of pocket costs, 32 and the state's involvement in the healthcare system. 33 Furthermore, follow-up and subsequent care are likely to have been organized very differently across the regions, including access to specialists, 23 as no international standards for follow-up existed at the time. Followup programs aim to facilitate care coordination and timely intervention and might in its absence have contributed to differences in overall satisfaction. Our study was not designed to link parental perceptions to specific health system features and this remains an area for further research. Differences in ratings could also be related to factors unrelated to the healthcare system. Research on adult patients has proposed that care satisfaction is to a large extent influenced by individual factors, such as personality, expectations about healthcare, and health status. 34 Patient expectations, in turn, have been associated with several characteristics, including patient age and educational level, 34,35 which could explain the association between parents' educational status and dissatisfaction in our study. Unknown broader societal factors 34 may explain the differences in ratings that remained across countries after adjusting for child health and parent sociodemographic factors. The subjectivity of the satisfaction measure in our study may accentuate the impact of individual and social factors, 36 which involve expectations and for which there is no common base level, 36 as well as different levels of "tolerance" toward service quality, which may depend on the general standard of living in the country. 36 This may partly explain the differences in ratings for native-, European-, and non-European-born mothers. Finally, the inclination to express dissatisfaction or complaints may also be cultural 37 and influence levels of dissatisfaction across countries, but there is, to our knowledge, little evidence on the impact of culture on care perceptions across Europe. The unexplained differences in parents' perceptions may partly mean that care satisfaction represents something different in each country. 38 The parents' suggestions concerning how healthcare could be improved were predominantly the same across countries. The suggestions were mainly organizational (follow-up coordination, provider training, access to services, and timeliness), but the most frequently mentioned subtheme concerned interpersonal aspects (healthcare-provider communication and relationship with parents). Similar themes have been found in other studies, 7,9,10,16,39,40 suggesting that healthcare providers may be subject to similar shortcomings regardless of follow-up content and healthcare context. Of note was that many parents had suggestions for improving healthcare despite rating their care as good or excellent, and these were largely similar to parents expressing dissatisfaction. This apparently paradoxical result suggests that even parents who are satisfied with their care in general experience difficulties with care coordination or have unsatisfactory interactions with providers.
Parents of children with health or developmental problems were less satisfied with healthcare, but few suggestions centered on health outcomes, medical quality, or technical aspects of care. Other studies have found that dissatisfaction with healthcare services does not necessarily reflect poor medical quality of care 7,22 but rather poor communication, especially when patients have major disabilities 41 or complex healthcare needs. 8 Additionally, poor organization of healthcare may become more apparent for parents whose children require complex multidisciplinary care compared to those with less complex health problems, not seeking healthcare to the same extent. It is also possible that dissatisfaction with health services has an impact on the further use of follow-up and health services, such as change of care provider, seeking care in the private sector, or discontinuing follow-up. We do not have data on unmet service need, which is particularly difficult to define in our European cohort because of differences in healthcare systems and this remains an area for further investigation. Our results are consistent with those from the Models of Child Health Appraised (MOCHA) study, which showed that European countries are failing to manage complex healthcare needs in the general pediatric population, with no policies for care coordination and care planning after discharge. 42 The lack of integrated healthcare systems for complex care manifests as a lack of multidisciplinary care and inconsistent healthcare provision depending on where care is sought and may ultimately negatively affect quality of care and health outcomes. 43 The parents' suggestions in our study coincide with policy improvements currently being recommended for the follow-up of preterm births, such as multidisciplinary follow-up, 44 follow-up until school age, 45 and parent support. 46 Further improvements based on parents' lived experiences should be considered in policy strategies.
Over one in ten children born very preterm received postdischarge care that their parents rated as poor or fair, with the highest rates for children who are most reliant on health services. Many parents provided suggestions for improving care, which centered on common themes, despite the wide geographic heterogeneity in ratings. Parents constitute a valuable resource for researchers and policy makers seeking to improve healthcare and for understanding failures in the healthcare system.
