BACKGROUND AND OBJECTIVE: Streptococcus pneumoniae is a major cause of pneumonia and sinusitis. Pneumonia kills >1 million children annually, and sinusitis is a potentially serious pediatric disease that increases the risk of orbital and intracranial complications. Although pneumococcal conjugate vaccine (PCV) is effective against invasive pneumococcal disease, its effectiveness against pneumonia is less consistent, and its effect on sinusitis is not known. We compared hospitalization rates due to sinusitis, pneumonia, and empyema before and after sequential introduction of PCV7 and PCV13. METHOD: All children 0 to <18 years old hospitalized for sinusitis, pneumonia, or empyema in Stockholm County, Sweden, from 2003 to 2012 were included in a population-based study of hospital registry data on hospitalizations due to sinusitis, pneumonia, or empyema. Trend analysis, incidence rates, and rate ratios (RRs) were calculated comparing July 2003 to June 2007 with July 2008 to June 2012, excluding the year of PCV7 introduction. RESULTS: Hospitalizations for sinusitis decreased significantly in children aged 0 to <2 years, from 70 to 24 cases per 100 000 population (RR = 0.34, P < .001). Hospitalizations for pneumonia decreased significantly in children aged 0 to <2 years, from 450 to 366 per 100 000 population (RR = 0.81, P < .001) and in those aged 2 to <5 years from 250 to 212 per 100 000 population (RR = 0.85, P = .002). Hospitalization for empyema increased nonsignificantly. Trend analyses showed increasing hospitalization for pneumonia in children 0 to <2 years before intervention and confirmed a decrease in hospitalizations for sinusitis and pneumonia in children aged 0 to <5 years after intervention. CONCLUSIONS: PCV7 and PCV13 vaccination led to a 66% lower risk of hospitalization for sinusitis and 19% lower risk of hospitalization for pneumonia in children aged 0 to <2 years, in a comparison of 4 years before and 4 years after vaccine introduction.
Aim This study evaluated the introduction of rotavirus vaccination in Jönköping County, Sweden, starting in 2014. This project explored the parental factors that influenced the decision to vaccinate and studied the obtained vaccination coverage and its potential influence on hospital admissions due to acute gastroenteritis. Methods This was a descriptive, cross‐sectional study based on a study‐specific questionnaire (n = 356) and regional statistical data on vaccination coverage and hospital admissions in Jönköping County, Sweden. Results Central aspects when deciding on vaccination were vaccine efficacy and safety, that the vaccine was offered to all children, and recommended by healthcare professionals. One in five parents expressed uncertainty about whether they had sufficient information to make a decision. However, the rotavirus vaccination coverage was elevated from 76.1% to 81.0% and the hospital admissions due to acute gastroenteritis decreased by approximately 60%. Conclusion The results highlight the necessity for Child Health Services to have solid knowledge regarding vaccinations, to understand individual parental issues and to support uncertain parents. The high vaccination coverage achieved is an indication of the trust in healthcare professionals and is considered to be a major contributing factor to the substantial reduction of hospital admissions due to acute gastroenteritis.
Early information, extra information for parents with less education and close positive relationships between parents and child health nurses were important factors in high rotavirus vaccination rates.
Results: Preseptal cellulitis was present in 171 of the 213 admissions, which equated to an incidence of orbital complications due to acute rhinosinusitis of 36 per 100 000 people per year (95% confidence interval 26-49). Postseptal complications occurred in seven cases. The incidence rate ratio for hospitalisation of children less than two years old with rhinosinusitis compared with children aged 2-5 years was 2.8 (95% confidence interval 1.8-4.4). The incidence among boys was 53 per 100 000 people per year and 36 per 100 000 people per year for girls, and the incidence rate ratio was 1.5 (95% confidence interval 1.0-2.3). The most common bacterial finding was Streptococcus pneumoniae.
Purpose Intussusception has been associated with rotavirus vaccine. The rotavirus vaccine will soon be introduced in the Swedish national immunization program. A validation of the diagnosis of intussusception among Swedish children in the Swedish National Patient Register is needed, as a basis for future vaccine safety surveillance by Swedish registers. Methods This diagnostic study reviewed the medical admission records of 392 Swedish children with intussusception from 1987 to 2013. The records were randomly selected by The National Board of Health and Welfare from all Sweden and from both pediatric and pediatric surgery care. Positive predictive values (PPV) were calculated to study the concordance between the diagnosis coded in the Swedish Patient Register and the accepted international criteria of case definitions. Results The PPV for a definitive diagnosis, based on certain radiology findings or surgery, was 84%. When clinically probable cases were added the PPV was 87%. When cases of possible intussusception were added the PPV was 89%. The PPV for the 240 children under 1 year was 88%. Conclusion Swedish health care registers can be used in the evaluation of incidences of intussusception when rotavirus vaccine will be introduced, due to a high validity of the diagnosis of intussusception in the registers.
Aim Routine immunisation programmes are at risk of disruption due to the COVID‐19 pandemic. This study aimed to investigate the resilience of the Swedish national immunisation programme for children up to the age of five years during the early stages of the pandemic. Methods This was a cross‐sectional, web‐based survey of regional child health offices in Sweden between 10 September and 9 October 2020. It explored the organisation of child health services during the early stages of the pandemic, focusing on routine child immunisation. Results All 21 Swedish regional child health offices responded. They stated that child immunisation had been prioritised, communication with families had been intensified and there was greater flexibility at all organisational levels of child health services. In addition, the vaccine supply was sustained and child health centres remained open. However, there were periodic staff shortages, increased numbers of health visits cancelled by parents and most parent education groups were paused. Conclusion The Swedish immunisation programme was resilient during the early COVID‐19 pandemic, thanks to sustainable organisation co‐ordinated by Sweden's network of regional child health offices.
Parental indicators associated with a lower level of health literacy increase the risk for hospital care due to gastroenteritis in young children. Information about oral rehydration should be provided in ways that are accessible to these parents.
In 2014, Stockholm became the first Swedish county to introduce the rotavirus vaccine, which is given from as early as six weeks of age. The aim of this study was to describe parental conceptions of rotavirus infection and vaccination during its implementation as part of the child immunization program, as their support is vital for any new vaccine. The study followed a descriptive, qualitative design with a phenomenographic approach. Ten in-depth interviews with parents were conducted in Stockholm County, transcribed and analyzed to describe qualitatively different conceptions of rotavirus infection and vaccination. Four main categories were identified: to vaccinate without doubt, hesitant to vaccinate, risky to vaccinate, and unnecessary to vaccinate. All the parents had in common the desire to protect their children from suffering, either by vaccinating their child in order to avoid rotavirus infection or by not vaccinating their child because of concerns about the side effects. It is important that child health-care professionals understand the variations of conceptions that influence the parents' decisions and that these conceptions may differ considerably. Individualized parental information about rotavirus infection and vaccination would help to achieve a successful implementation of the vaccination program.
