THE head of cancer treatment at Tweed Hospital is scathing over the hospital's exclusion from a recent NSW Health report into patient satisfaction of oncology treatment.

Tweed Cancer and Aged Care lead Dr Ehtesham Abdi slammed the Bureau of Health Information and Cancer Institute's report on 3700 people using cancer outpatient services, saying it failed to include the Tweed.

"I have discussed the omission of Tweed with the people who wrote the report and they have given me some cock and bull story about having to spend the Cancer Institute money before that financial year," Dr Abdi said.

Northern NSW Local Health District chief executive Wayne Jones said the reason for the exclusion was due to "inadequate data" for the sampling period from February to March 2015.

"The BHI state there was insufficient time to approach individual hospitals to request manual submission of data when it was not available in WebNAP," Mr Jones said.

"Due to ongoing issues in WebNAP, no patient level data was available for (Tweed Hospital)."

But Dr Abdi, who has previously criticised the Health District and its board for the Tweed cancer clinic repeatedly missing out on government funding, said he found the reason "hard to believe".

"It is another example of our not being on NSW Health or Cancer Institute's radar," Dr Abdi said.

Dr Abdi said the Tweed was "always left off the system" due to its location on the border of Queensland and NSW.

"Albury get their funding from (the Victorian Government) and they never get left behind," Dr Abdi said.

"They are in the process of getting a brand new cancer centre.

"Such is our lot - we lose out every way possible."

Mr Jones said the 2015 report for Tweed showed "favourable results from cancer patients surveyed".

"Our staff routinely receive positive feedback and compliments on the cancer care they have provided," Mr Jones said.

The report found 92% of Lismore Base Hospital patients rated their experience as "very good".

But overall, 12% of NSW patients said they experienced a complication and 15% of those said the impact of "the complication was very serious".
