Barbados needs a sustainable healthcare financing plan, given the significant issues plaguing the sector, says Minister of Health, Senator The Most Honourable Dr Jerome Walcott.And that plan, he said on Tuesday, could potentially result in the Government broadening the tax system from which healthcare is partially funded.He made the disclosure on day one of the four-day International Review of Health Financing Reform Options in Barbados at the Hilton Hotel.During the event, hosted in collaboration with the World Health Organisation and the Pan American Health Organisation, Minister Walcott said the island’s healthcare system was under strain and there was a need for a sustainable reformative framework.
