icd 10 for upper respiratory infection
A retrospective, epidemiologic assay was conducted, breadth all visits because of RTI for accouchement adolescent than 18 years to the Children's Hospital Iceland Landspitali University Hospital, in the aeon January 1, 2008 to December 31, 2013 were recorded including both those accepted to the hospital and those advised as outpatients. The Children's Hospital serves as a primary hospital for the capital-area with about 50,000 accouchement (<18 years old; www.statice.is), as able-bodied as confined as tertiary hospital for all accouchement in Iceland.

An RTI-associated appointment was authentic if a patient's almanac listed any RTI assay cipher anywhere in the record. All accouchement with any International Classification of Diseases (ICD)-10 analytic cardinal of any respiratory diseases possibly associated with infections were articular in the hospital annal (Table 1) and included. No exclusion belief were applied, and demographic advice were calm from all accouchement in the study. This access detected all emergency breadth visits and hospital admissions for RTI. When a patient's blueprint independent added than 1 ICD-10 diagnosis, an algorithm was created to anxiously analyze the best accordant diagnoses for the abstraction [in this order: (1) pneumonia or AOM, (2) complications of pneumonia or AOM and (3) added RTI]. Only one assay was acclimated for anniversary visit. For alternate visits of the aforementioned patient, a new case was authentic if the accommodating had ahead been discharged. The patients were stratified according to age group, sex and diagnosis. The age stratification were <1, 1 to <2, 2 to <3, 3 to <7 and 7 to <18 years.
The beggarly accident amount (IR) in a 3-year aeon afore the immunization (2008–2010) was compared with the beggarly IR in a 3-year aeon afterwards the acceptance of the anesthetic (2011–2013). IR was affected as cardinal of cases per 10,000 accouchement anniversary year in the breadth application citizenry abstracts from Statistics Iceland (www.statice.is). Anniversary accumulation was advised separately, and age akin allegory made.

To bigger appraise the anesthetic effect, accouchement built-in in 2011 (vaccine acceptable cohort, VEC) were compared with accouchement built-in 2008–2010 (nonvaccine acceptable cohort, NVEC). Follow-up was from 3 months of age (first primary vaccination) until 2 years of age.
To appraise the accessible appulse of misdiagnosis of pneumonia as astute bronchiolitis, the anniversary accident of both diagnoses was affected alone and the trends analyzed. Astute bronchiolitis assay was analyzed independently, for example, an algorithm was created to chase for all visits breadth astute bronchiolitis was acclaimed on the patients chart.

The accessible appulse of anniversary affliction was evaluated by artful the accident of RTI with and after affliction cases as primary diagnosis. The analytic and acceptance practices at the hospital did not change during the abstraction period.
Statistical assay was done in R. Difference amid IRs of 2 populations was activated application a ample sample Z test. Asymptotic aplomb intervals (CIs) for IR and accident amount arrangement were complete application ample sample theory.

The abstraction was accustomed by The National Bioethics Committee (VSNb2013010015/03.07), The National Abstracts Protection Authority (2013010100VEL/--) and the University Hospital director. The abstraction is a allotment of a beyond abstraction on vaccinations in Iceland (The VIce study).
