Medical practitioners fear a funding reduction for a rural allied health services will put more pressure on Tasmania's health system, with one mobile service expected to close in July.

Funding for Tasmanian rural health outreach programs will drop from $4 million to just $1.5 million next month.

Nursing practitioner Lisa Sproule runs one of the allied health services, providing occupational therapists, dieticians, nurses and speech pathologists to remote areas of the East Coast and Tasman Peninsula.

She said the cut to the funding will hit her organisation hard.

"At the end of the month those services will cease, which is going to mean a significant deficit and a lot more burden on the public sector," she said.

"My fear is that we are going to be seeing crisis, and not prevention."

Ms Sproule said the organisation was hoping for a lifeline, but has stopped taking on new patients.

Bob Dixon, 80, takes 19 different pills every day and said the help he gets from the service was crucial.

"Sometimes you're a bit down in the dumps and they have a talk to you and explain things to you and it gives you a better attitude, better feeling," he said.

More pressure on the public system

Bastian Seidel from the Royal Australian College of General Practitioners said discontinuing funding could cost the health system more.

"It's a false economy absolutely, we are not saving any money but even more importantly we are not improving any patient outcomes," he said.

"It's a complete disaster, I call it a double whammy on top of the Medicare rebate freeze, you will not be finding any private allied health practitioners who are more into rural areas."

Greens Senator Nick McKim wants both major political parties to commit to restoring the funding.

He is concerned the move could send even more patients into an already over-stretched system.

"I mean regional Tasmanians have been shafted here by the Liberals, and it's now up to all candidates in this Federal election to step up, back in local allied health services," he said.

"This is potentially a lose-lose situation, we risk putting extra pressure on already overloaded hospitals in places like Hobart and Launceston, but the further risk is because of the massive inconvenience people will actually not be able to access their health services."

A spokeswoman for the Federal Health Department said service plans for the coming financial year had not been finalised and the specific services to be delivered had not been confirmed.
