Abstract
BackgroundThe incidence of acute otitis media (AOM) vary from country to country. Geographical variations together with differences in study designs, reporting and settings play a role. We assessed the incidence of AOM in Italian children seen by primary care paediatricians (PCPs), and described the methods used to diagnose the disease.MethodsThis secondary data analysis from the Pedianet database considered children aged 0 – 6 years between 01/2003 and 12/2007. The AOM episodes were identified and validated by means of patient diaries. Incidence rates/100 person-years (PY) were calculated for total AOM and for single or recurrent AOM.ResultsThe 92,373 children (52.1% males) were followed up for a total of 227,361 PY: 23,039 (24.9%) presented 38,241 episodes of AOM (94.6% single episodes and 5.4% recurrent episodes). The total incidence rate of AOM in the 5-year period was 16.8 episodes per 100 PY (95% CI: 16.7-16.9), including single AOM (15.9 episodes per 100 PY; 95% CI: 15.7-16.1) and recurrent AOM (0.9 episodes per 100 PY; 95% CI: 0.9-0.9). There was a slight and continuously negative trend decrease over time (annual percent change −4.6%; 95%CI: -5.3, -3.9%). The AOM incidence rate varied with age, peaking in children aged 3 to 4 years (22.2 episodes per 100 PY; 95% CI 21.8-22.7). The vast majority of the AOM episodes (36,842/38,241, 96.3%) were diagnosed using a static otoscope; a pneumatic otoscope was used in only 3.7%.ConclusionsOur data fill a gap in our knowledge of the incidence of AOM in Italy, and indicate that AOM represents a considerable burden for the Italian PCP system. Educational programmes concerning the diagnosis of AOM are needed, as are further studies to monitor the incidence in relation to the introduction of wider pneumococcal conjugate vaccines.

Study design and setting This secondary data analysis was based on data coming from the Pedianet database, a pediatric general practice research database that contains the clinical, demographic, prescription and outcome data of the children routinely seen by about 130 primary care paediatricians (PCPs) distributed throughout Italy, and which has been used for various epidemiological and pharmacovigilance studies [26,27,28,29]
Summary
Geographical variations together with differences in study designs, reporting and settings play a role. The incidence of AOM varies from country to country both because of geographical variations and of different study designs, reporting and settings [10,11,12,13,14,15]. In the last decade the introduction of pneumococcal conjugate vaccines has dramatically reduced invasive pneumococcal diseases [21]. In light of the potential impact against non-invasive diseases such as middle ear infections, there has been a continuing interest in defining the incidence and burden of AOM in different populations, including those in which the offer and coverage of heptavalent pneumococcal conjugate vaccine has been considerably heterogeneous [22,23,24,25]
