Aims-To compare the use of health care resources and associated costs between infants with chronic lung disease (CLD) who had or had not an admission with a proven respiratory syncytial virus (RSV) infection. Methods-Review of community care, outpatient attendances, and readmissions in the first two years after birth. Patients: 235 infants (median gestational age 27 weeks) evaluated in four groups: 45 infants with a proven RSV admission (RSV proven); 24 with a probable bronchiolitis admission; 60 with other respiratory admissions; and 106 with non-respiratory or no admissions. Results-The RSV proven compared to the other groups required more frequent and longer admissions to general paediatric wards and intensive care units, more outpatient attendances and GP consultations for respiratory related disorders, and had a higher total cost of care. Conclusion-RSV hospitalisation in patients with CLD is associated with increased health service utilisation and costs in the first two years after birth.

Background: In prematurely born infants with chronic lung disease (CLD), RSV hospitalisation is associated with increased health service utilisation and costs in the first two years after birth. Aims: To determine whether RSV hospitalisation in the first two years was associated with chronic respiratory morbidity during the preschool years in prematurely born children who had had CLD. Methods: Retrospective review of readmissions, outpatient attendances, and community care in years 2-4 and, at age 5 years, assessment of the children's respiratory status and their health related quality of life. Comparison was made of the results of children who had had at least one hospitalisation in the first two years after birth for RSV infection (RSV group) to those of the rest of the cohort. Participants were 190 of an original cohort of 235 infants with CLD and a median gestational age 27 (range 22-33) weeks. Results: The 33 children in the RSV group, compared to the rest of the cohort, had a greater duration of hospital stay and more outpatient appointments. The RSV group had required more prescriptions for all treatments and respiratory medications, and more had used an inhaler. The cost of care of the RSV group was higher (median £2630 [J4000, US$4800], range £124-18 091 versus £1360 [J2500, US$3000], range £5-18 929) and their health related quality of life was lower. Conclusion: In prematurely born children who had developed CLD, RSV hospitalisation in the first two years was associated with chronic respiratory morbidity and increased cost of care.

Background: Hospitalisation due to respiratory syncytial virus (RSV) infection in the first 2 years after birth has been associated with increased healthcare utilisation and associated costs up to 5 years of age in children born prematurely at less than 32 weeks of gestation who developed bronchopulmonary dysplasia (BPD). A study was undertaken to determine whether hospitalisation due to RSV infection in the first 2 years was associated with increased morbidity and lung function abnormalities in such children at school age, and if any effects were influenced by age. Methods: Healthcare utilisation and cost of care in years 5-7 were reviewed in 147 children and changes in healthcare utilisation between 0 and 8 years were assessed also using results from two previous studies. At age 8-10 years, 77 children had their lung function assessed and bronchial hyper-responsiveness determined. Results: Children hospitalised with RSV infection (n = 25) in the first 2 years had a greater cost of care related to outpatient attendance than those with a nonrespiratory or no admission (n = 72) when aged 5-7 years (p = 0.008). At 8-10 years of age, children hospitalised with RSV infection (n = 14) had lower forced expiratory volume in 0.75 s (FEV 0.75 ) (p = 0.015), FEV 0.75 /forced vital capacity (p = 0.027) and flows at 50% (p = 0.034) and 75% (p = 0.006) of vital capacity than children hospitalised for non-RSV causes (n = 63). Healthcare utilisation decreased with increasing age regardless of RSV hospitalisation status. Conclusions: In prematurely born children who had BPD, hospitalisation due to RSV infection in the first 2 years is associated with reduced airway calibre at school age.Respiratory syncytial virus (RSV) infection in previously healthy term-born infants is associated with increased respiratory problems at follow-up.
