Objective: Internet plays a huge role in providing information about health care problems. However, it is unknown how parents use and perceive the internet as a source of information and how this influences health care utilisation when it comes to common complaints in infants. The objective was to evaluate the perception parents have on the role of internet in providing health care information on common symptoms in infants and its effects on health care utilisation., Design: A qualitative design was chosen., Setting and Subjects: Parents were recruited from a population-based birth-cohort and selected purposefully., Main Outcome Measures: Semi-structured interviews were used to receive information of parents' ideas. Thematic coding and constant comparison were used for interview transcript analysis., Results: Ten parents were interviewed. Parents felt anxious and responsible when their child displayed common symptoms, and appeared to be in need of information. They tried to obtain information from relatives, but more so from the internet, because of its accessibility. Nevertheless, information found on the internet had several limitations, evoked new doubts and insecurity and although parents compared information from multiple sources, only the physician was able to take away the insecurity. The internet did not interfere in the decision to consult the physician., Conclusions: Parents need information about their children's symptoms and the internet is a major resource. However, only physicians could take away their symptom-related doubts and insecurities and internet information did not play a role in parental decision making. Information gathered online may complement the information from physicians, rather than replace it. Key points Internet plays an increasing role in providing health care information but it is unknown how this influences health care utilisation. Our study suggests that: Parents need information about their children's symptoms and the internet is a major resource. However, only physicians could take away their symptom-related doubts and insecurities. Internet information did not play a role in parental decision making.

Background: Most estimates of the incidence of acute otitis media (AOM) are based on general practitioner (GP) or pediatrician diagnoses. It is likely that these figures underestimate the community incidence of AOM since parents do not visit their doctor every time their child suffers from acute ear symptoms. The impact of these symptom episodes may be substantial since they affect the child's quality of life and parents' productivity., Methods: To determine AOM symptoms in the community, we measured parent-reported AOM symptoms daily for 12 consecutive months in 1,260 children participating in a prospective birth cohort in the Netherlands. The mean age of these children was at study enrollment 0.9 months (standard deviation 0.6). A parent-reported AOM symptom episode was defined as fever (temperature 38˚C or above) plus at least one of the following symptoms: ear pain and ear discharge. These febrile AOM symptom episodes were linked to GP-consultations and diagnoses in the GP electronic health records., Results: With an estimated 624 parent-reported symptom episodes per 1,000 child-years (95% CI: 577 to 674) incidence of febrile AOM symptoms during the child's first year is high. The GP was consulted in half of these symptom episodes and AOM was diagnosed in 49% of these consultations., Conclusions and Relevance: The incidence of febrile AOM symptoms in the first year of life is high in Dutch children and leads to a GP-consultation in only half of the cases. This suggests that AOM symptomatology in the community is underestimated when focusing on GP-diagnosed AOM episodes alone, since a considerable proportion of febrile AOM symptom episodes are treated symptomatically by parents at home and do not come to the attention of the GP. Having data on community AOM symptomatology available for each country is important when the potential impact of preventive and therapeutic interventions for AOM are studied.

Background: It is assumed that clear and complete information on the internet can reduce healthcare consumption., Aim: We assessed in a randomised clinical trial whether a personalised online parent information program on infant respiratory symptoms can reduce primary care utilisation., Design and Setting: Randomised clinical trial in primary healthcare centres in a new residential area in the Netherlands., Method: A web-based program (WHISTLER-online) was developed for parents that offered general information on childhood respiratory disease and personalised risk assessments. Parents of infants who enrolled from June 2009 to June 2012 in WHISTLER, an ongoing population-based birth cohort, were randomly allocated to 'WHISTLER-online' or 'usual care'. Information about, first, consultations and, second, associated prescriptions for respiratory symptoms during the first year of life was collected from the electronic patient files., Results: A total of 323 infants were randomly assigned to WHISTLER-online and 322 to usual care, and 314 and 305, respectively, were analysed. Of the parents, 70% used WHISTLER-online, and 99% of them judged it to be clear and useful information. There were differences neither in consultation rates for respiratory symptoms (incidence rate ratio 0.96 [95% CI = 0.85 to 1.09, P = 0.532]) nor in associated drug prescriptions., Conclusion: Although parents greatly appreciate the provided facilities, a personalised e-support program on respiratory illnesses in infants does not substantially reduce healthcare utilisation., (© British Journal of General Practice 2015.)

It is unknown why respiratory syncytial virus (RSV) causes mild disease in some children and severe disease, requiring hospitalisation, in others. We aimed to assess whether diminished premorbid lung function in healthy term infants predisposes to hospitalisation during RSV bronchiolitis, and to post-RSV wheeze. In a prospective birth cohort study of unselected term healthy children, neonatal lung function was measured before the age of 2 months (n=2133). From birth through the first year of life, respiratory symptoms were recorded in a diary, and general practitioner consultations and hospitalisations were documented. In a subgroup (n=417) repeated nose and throat swabs were collected for PCR to detect RSV infections. Median neonatal respiratory system compliance (Crs) was significantly lower (41.2 versus 47.4 mL · kPa(-1), p=0.03) and resistance (Rrs) was higher (8.2 versus 6.3 kPa · s · L(-1), p=0.10) in hospitalised RSV patients (n=18) compared with nonhospitalised RSV-positive infants (n=84). Every 10 mL · kPa(-1) increase in Crs was associated with 55% less post-RSV wheeze (OR 0.56, 95% CI 0.35-0.90), and each kPa · s · L(-1) increase in Rrs was associated with 42% more post-RSV wheeze, which was only marginally explained by pre-RSV wheeze or severity of the RSV disease. This unselected birth cohort study shows for the first time that decreased lung function at birth predisposes to severe RSV disease, and to post-RSV wheeze., (©ERS 2014.)

Studies of reduced neonatal lung function and wheezing illnesses during childhood show conflicting results. The aim of our study was to assess the association between resistance (Rrs) and compliance (Crs) of the respiratory system by using the single occlusion technique (SOT) and prospectively collected wheezing illnesses during the first 5 years of life in a large birth cohort. SOT was performed during natural sleep before the age of 2 months. Information about wheezing illnesses was collected from the electronic patient file. 549 infants had a successful SOT measurement and complete medical records. Every kPa·L(-1)·s(-1) increase in Rrs was associated with 10% more consultations in the first 3 years of life. Every 10 mL·kPa(-1) increase in Crs was associated with a 14% reduction in consultations in the first 3 years of life, 27% in the fourth to fifth years of life, and a lower probability of having asthma at the age of 5 years (OR 0.66). Children with late-onset or persistent wheezing had significant lower Crs values than their peers. An increased neonatal resistance is associated with more wheezing illnesses during infancy, while a reduced neonatal compliance is associated with more wheezing illnesses during the first 5 years of life, a late-onset or persistent wheezing phenotype, and asthma.

The aim of our study was to investigate the association between rapid weight gain in the first 3 months of life and the prevalence of wheeze in the first years of life and lung function at 5 yrs of age. The infants selected were participating in an ongoing birth cohort. Information on growth and respiratory symptoms was collected during the first year of life, and on primary care consultations during total follow-up. Forced expiratory volume in 1 s (FEV(1)) and forced expiratory flow at 25-75% of forced vital capacity (FEF(25-75%)) were measured at 5 yrs of age. Information on growth and respiratory symptoms was obtained for 1,431 infants, out of whom 235 children had already had 5 yrs of follow-up. Every one-point z-score increase in weight gain resulted in a 37% increase in days with wheeze (incidence rate ratio 1.37, 95% CI 1.27-1.47; p<0.001) and in associated consultations by 16% (incidence rate ratio 1.16, 95% CI 1.01-1.34; p=0.04). Children with rapid weight gain reported significantly more physician-diagnosed asthma. FEV(1) and FEF(25-75%) were reduced by 34 mL (adjusted regression coefficient -0.034, 95% CI -0.056- -0.013; p=0.002) and 82 mL (adjusted regression coefficient -0.082, 95% CI -0.140- -0.024; p=0.006) per every one-point z-score increase in weight gain, respectively. These associations were independent of birthweight. Rapid early weight gain is a risk factor for clinically relevant wheezing illnesses in the first years of life and lower lung function in childhood.
