Unfortunately, lack of a website I can use on my desktop browser makes this unusable for me. Also I am not sure any of the user generated content on this app would be discoverable by search engines. I fear it will be locked in forever.
You have to remember that you are not the only patient in the hospital. A Caesarean section requires a lot of setup including OR, anesthesiologist, ensuring adequate care for the newborn, etc. Any of these can cause a delay. Of course there is other cases triaged by urgency like crash sections. It would make no sense to show up to the OR 30 minutes before you can begin operating. An elective Caesarean section will always get bumped for emergencies.
