Economies of masses(scale) can work well in healthcare for private providers.
Five major reasons for the same are-
1. Poor economic background of patient.
2. Health is still considered as welfare project.
3. Privatization and corporate hospitals have got so called "loot/mahnaga" status in tier 3 districts and villages.
4. Absence of mediclaim coverage and awareness in medioker class, which is not covered by government schemes like Bhamashah yojna.
5. Poor show of government health structure.
In such scenarios trust hospitals and low cost providers are clear cut winners in the long run in tier 3 areas.
They get donations from trust for their infrastructure(machinery and building), which is the costliest part.
And "social initiatives" are doing extremely good, for example-Arvind eye care. Some of them are grown really big.
So if you are enthusiast to provide health to the masses,got passion,got connections in medical fraternity or belongs to medical field. This is one of the satisfaction giving & reputation earning welfare-cum-livelyhoodearning opportunity for you.
