In a statement the IOMMS said it recognised the “importance of developing a coherent and sustainable framework for private healthcare provision on the island”.
The society said it could reduce current pressures on public services and encourage experienced specialists to move to the island to practice.
But it raised concerns about the possibility of independent private facilities “inadvertently” increasing average healthcare costs per person “by leaving a disproportionate number of complex cases to an under-resourced and understaffed public sector”.
It also suggested the delayed reopening of the PPU had meant a “substantial loss of potential revenue” to Manx Care and the Treasury.
Calling for the Manx parliament to undertake a “comprehensive public review” into the future of private healthcare, the IOMMS said it should assess “clinical need and commercial intent”, with input from public and private stakeholders.
The role of the PPS should be “central to any review” as it offered a “viable means of returning locally generated revenues” to benefit all Manx residents “rather than external shareholders”, it added.
