There was a massive decline in the demand for most health services because individuals avoided elective care out of concern about exposure to Covid-19. This stresses the finances of hospitals since the profitability of elective services is much higher.
Hospitals have largely bounced back to a pre-Covid-19 baselines, but they face uncertainty this coming winter about the extent to which elective health care will decline again. In the meantime, many physicians have retired or otherwise exited patient care. A Physicians Foundation survey of 3,500 doctors in mid-July found that "In addition to the eight percent of physicians who indicated they had closed their practices within the previous four months, four percent of physicians surveyed said they plan to close their practices within the next 12 months." If elective care falls again, there could be another wave of exits.
