Can nurses exclude middle-ear effusion without otoscopy in young asymptomatic children in primary care?

Laine MK, Tähtinen PA, Ruuskanen O, Löyttyniemi E, Ruohola A - Scand J Prim Health Care (2015)

Bottom Line: The negative predictive value of SG-AR level 1 result was 86% (79-91%).Tympanograms with tympanometric peak pressure > -200 daPa (types A and C1) obtained by nurses are reliable test results in excluding MEE.However, these test results were obtained at less than half of the asymptomatic visits and, thus, the usefulness of excluding MEE by nurses depends on the clinical setting.

ABSTRACT

Objective: Scandinavian guidelines recommend controlling middle-ear effusion (MEE) after acute otitis media. The study aim was to determine whether nurses without otoscopic experience can reliably exclude MEE with tympanometry or spectral gradient acoustic reflectometry (SG-AR) at asymptomatic visits.

Design: Three nurses were taught to perform examinations with tympanometry and SG-AR. Pneumatic otoscopy by the study physician served as the diagnostic standard.

Setting: Study clinic at primary health care level.

Patients: A total of 156 children aged 6-35 months.

Main outcome measures: Predictive values (with 95% confidence interval) for tympanometry and SG-AR, and the clinical usefulness, i.e. the proportion of visits where nurses obtained the exclusive test result from both ears of the child.

Results: At 196 visits, the negative predictive value of type A and C1 tympanograms (tympanometric peak pressure > -200 daPa) was 95% (91-97%). Based on type A and C1 tympanograms, the nurse could exclude MEE at 81/196 (41%) of visits. The negative predictive value of SG-AR level 1 result was 86% (79-91%). Based on SG-AR level 1 results, the nurse could exclude MEE at 29/196 (15%) of visits.

Conclusion: Tympanograms with tympanometric peak pressure > -200 daPa (types A and C1) obtained by nurses are reliable test results in excluding MEE. However, these test results were obtained at less than half of the asymptomatic visits and, thus, the usefulness of excluding MEE by nurses depends on the clinical setting.

Mentions: This study included 156 children who had 196 asymptomatic visits when a nurse performed tympanometry and/or SG-AR on one or both ears (Figure 1). The prevalence of MEE with pneumatic otoscopy by the study physician was 206/753 (27%) of all ears examined by the nurse.
