Long-Term Follow-Up Shows Higher CPAP Compliance
So what’s different in the most recent study of educational videos and CPAP compliance? The follow-up. The big challenge with CPAP compliance is long-term compliance. CPAP usage tends to drop off over time, with significantly fewer people using their CPAP machines after a year or more. Researchers wanted to test whether educational videos could make their mark there, so they set up a study with patient recalls at two months and a year after their initial session.
At the two-month recall, researchers saw the same effect as the 2017 study: people who saw the videos used their CPAP for less time than people who got usual care: 3.45 hours per night for the video group vs. 3.75 hours per night for the usual care group. This difference was not statistically significant.
However, at the 12-month recall, the difference favored the videos group. At this recall, the usual care group used their CPAP machines for an average of 2.5 hours per night, but the video group used their CPAP for an average of 3.66 hours per night, which was a statistically significant difference.
The improvement was particularly significant for people who had a low educational background. These patients tended to use their CPAP for an average of 2.47 hours more per night after watching an educational video than they did after receiving the usual care.
