I don't have concrete metrics/sources to give right now, but my general perception from reading the news is that there's been staffing issues pushing healthcare systems in the US towards increasing workloads in individual providers, leading to less time/attention given to individual patients, lower availability of appointment slots, and offloading of patients onto alternative app-based telehealth platforms, which have been trending up alongside aquisition/consolidation of independent private practices.
Staffing problems are absolutely everywhere, regardless of the particular healthcare system or even political system. Czechia, the UK, China, Japan. It seems to be a global trend, much like falling birthrates.
