A new bid to combat hospital infections is launched.

A senior medical officer said health care-associated infections could prolong a patient's stay or, in some cases, cause death.

The MRSA "super bug" played a part in 116 deaths in Northern Ireland in the past seven years.

Dr Lorraine Doherty said the strategy would tackle such infections "head-on".

More than 300 cases of MRSA were discovered among patients last year, compared to just under 500 cases reported between 2001 and 2003.

Nearly three-quarters of deaths associated with infections picked up in hospitals occurred in the over-75 age group.

The MRSA (methicillin resistant Staphylococcus aureus) infection is a strain of skin and nose bacterium which has become resistant to commonly prescribed antibiotics.

Speaking at the launch of the strategy document in Belfast's Mater Hospital, Dr Doherty said the fight against infections such as MRSA was one of the health service's highest priorities.

"The strategy includes plans for an annual infection reduction plan, a hand hygiene campaign and mandatory training for all health care staff," she said.

Dr Doherty said the strategy correctly identified areas where improvements needed to be made.

Protecting patients

She said recommendations included a stronger accountability framework, ongoing professional training for health care workers, enhanced surveillance systems and the sharing of information and best practice.

"The document also stresses the crucial fact that protecting patients and staff from infection is everyone's responsibility," Dr Doherty said.

"This principle is central to the success of this strategy and will require a major change in how we, as health care professionals, do our business."

She said the strategy would also require hospital patients and visitors to be better informed and aware of the risks of infection and how to prevent it.

The strategy has been put forward for a three-month public consultation period.

At the end of this process, the Department of Health and Social Services will assess responses and work with the Health Personnel and Public Safety department to develop an action plan for implementation.
