The best approach remains to know the right people who can tell you about which doctors are good. Or as the kids call it,"networking". E.g. my dentist (an exceptionally good and professional woman) is someone I know because she's friends with the wife of a colleague of a girl I went to high school with. I hope that the new health platforms that are springing up will lead to knowledge of which doctors are worth their pay being easier to access and spread.
Its a business and you have 10m to do all paper work, check patient and prescript something.
Its horrible. Doesnt help that private doctors are super expensive, dont care about you and dont believe you.
Health became just another accommodity only super rich can pay for.
