TWEED paramedics have ramped up their fight for a staffing review after it was revealed an elderly Tyalgum woman waited on the floor with a broken arm for more than an hour last month before an ambulance arrived.

North Coast Health Services Union boss Ken McIntosh has blamed the NSW Ambulance Service for the extended response times and staff shortages, claiming it prioritised saving money over saving lives.

He said new on-call guidelines aiming to reduce fatigue and overtime meant patients with non-life-threatening injuries such as broken limbs were waiting too long.

His claims follow a seemingly endless of list of cases where patients have waited hours for an ambulance, including a case in Murwillumbah where a man suffering cardiac arrest died before help arrived 27 minutes later.

Non-life-threatening cases have included a kidney dialysis patient from Myocum who called triple-0 three times suffering leg pains. She waited two-and-a-half hours.

The NSW Ambulance Service also tasked NSW Fire and Rescue personnel to help an elderly woman who had fallen over in her Tweed Heads home.

Mr McIntosh said the union was demanding a complete review of staffing across the service.

A NSW Ambulance Service spokesman said paramedics who were paid to be on call would only respond to emergencies when and as required.

Tweed MP and Parliamentary Secretary for Police and Emergency Services Geoff Provest said he hoped a staffing review would be included in the Tweed Hospital Clinical Services Plan due to be released early next year.
