Day-surgery in otology: Impact study of a dedicated organizational model.

AIM: Day surgery (DS) in otology in France is insufficiently implemented compared to other countries of comparable socio-economic level. The aim of the present study was to evaluate changes in surgical practice in "major otology" cases in a hospital center after launching a dedicated ENT DS unit.

MATERIAL AND METHODS: This new unit, designed in collaboration with the surgeons, was inaugurated in 2014. Number of procedures, patient demographics, surgery durations, and rates of crossover from DS to conventional management were recorded prospectively for the year before and the year after the launch. All otologic surgery procedures with at least tympanomeatal flap elevation were included; minor surgeries such as grommet insertion were excluded.

RESULTS: Between the two time periods, major otology day cases increased from 106 to 153 procedures (+43%). In 2013, the DS rate was 27%, versus 56% in 2015. Otosclerosis surgeries represented 7% in 2013 and 15% in 2015, and type II and III tympanoplasties 3% and 24% respectively. Difference in patient age between DS and conventional surgery was lower in 2015. Crossover rates were 10% in 2013 and 21% in 2015, mainly due to nausea/vertigo (56%) and surgery ending too late in the day (33%).

CONCLUSION: Major otologic cases are suitable for DS. Launching this dedicated unit with its specific organization enabled a very significant increase in DS rates, probably due to greater patient satisfaction and surgeons' growing confidence. The main pitfall was in scheduling, with surgery ending too late in the day for discharge home; this has since been corrected.
