Adding my uneducated guess:<p>- there's some evidence that healthcare in general can benefit from deliberate less intervention by patients and medical staff [0]<p>- maternity intervention is notorious for intervention (historically for good reasons) yet, today, so much extra can be profited by just pre-planning interventions that are distorting incentives [1]<p>- pandemic has raised the stakes of leaving home, particularly visiting hospitals so people think twice before deciding to go for intervention - patients preserveer more. That includes expecting mothers.<p>[0] this an opinion <a href="https://www.theguardian.com/commentisfree/2014/jul/19/patients-hospital-care-over-intervention" rel="nofollow">https://www.theguardian.com/commentisfree/2014/jul/19/patien...</a><p>[1] <a href="https://www.wilsoncenter.org/event/too-much-too-soon-addressing-over-intervention-maternity-care" rel="nofollow">https://www.wilsoncenter.org/event/too-much-too-soon-address...</a>
