[Evaluation of the notification of dysphonia on the voice profesionals as a sentinel event in Navarra. Period 2013-2015.].

OBJECTIVE

Among the lesions produced by the professional use of the voice since 2007, the Vocal Nodules (VN) are recognized in Spain as an Occupational Disease. With the aim of promoting its notification in Navarre, the Sentinel Program was incorporated in 2013 and, with this study, we seek to verify its efficacy.

METHODS

The study population were voice professionals reported for dysphonia as sentinel events during the years 2013 to 2015 in Navarre. Its effectiveness was validated by the cumulative incidence of 100,000 workers for each of the years and Positive Predictive Value as an indicator of suspicion. The declaration was verified as an occupational disease.

RESULTS

In the period April 2013 to December, 110 cases were reported, 71 nominal and 39 non-nominal. The annual incidence increased from 9.0 cases per 100,000 to 13.4. Of the cases investigated, 63 were women and 8 men. The mean age was 40.8 years (38.5-43.1 95% CI). 58 cases (81.7%) corresponded to teachers. In 22 of the 71 nodules (31%) and 9 coincidences were notified as an occupational disease. We found a greater presence of nodules in professionals with extra work use of voice (OR 4.2 IC 1.3-14.3) and better evolution of pathologies other than VN (OR = 2.5 CI 1.1-5.8 ). The suspicion was confirmed as occupational in 54 cases (positive predictive value 76.1%).

CONCLUSIONS

The centinel program is effective in reporting dysphonia although it is important to highlight the low declaration as occupational disease of the cases detected.
