There's a similar phenomenon when you look at fetal heart monitoring for otherwise healthy pregnant women going into labour. The two options are continuous monitoring, where the monitor is left in place for the entire hospital stay, and periodic monitoring, where a nurse installs it, takes a reading, and removes it about once an hour.
Common sense would dictate that negative outcomes are reduced with continuous monitoring, but it's actually the opposite, because the odds of the monitor detecting something in the intervening time and the intervention being correct are lower than the odds of the intervention causing some other unwanted side effect.
