Connolly hospital has most heart deaths in Dublin
DUBLIN's Connolly Hospital at Blanchardstown has one of the highest death rates from heart attack in the country.
The data, compiled by the hospitals themselves, is contained in the first report of its kind released by the Department of Health showing death rates from heart attack and stroke.
The national death rate within 30 days of admission to hospital due to heart attack is 6.68 deaths per 100 cases - but Connolly's figure is at 9.87.
Tullamore's rate per 100 cases, tracked between 2011 and 2013, was a huge 11.96, followed by Cavan at 10.36.
Chief medical officer Dr Tony Holohan cautioned that while the rate was standardised by age and sex, it does constitute a "league table" and does not show if quality of care is at fault.
He pointed out that there are other factors - such whether the patient was transferred from another hospital or had other illnesses, which all need to be taken into account.
However, he said the figures are a signal that more investigation is needed and it is up to each hospital to now start measuring its performance and find where there are weaknesses.
Death rates from heart attack generally in Ireland have dramatically fallen in the last decade.
"There is no such thing as perfect data but the indicators presented in this report signal to us that certain services require further analysis and examination in order to identify if a problem exists," he added.
The best performing hospital for death rates for heart attack patients is Portlaoise which recorded a rate of 3.84 per 100 cases with the Mater in Dublin coming in second.
The report showed the death rate within 30 days of admission for the most common form of stroke - ischaemic stroke - was highest in Cavan, Cork University Hospital and Connolly and lowest in Tallaght, Portiuncula and Sligo General.
The death rate from another from of haemorrhagic stroke, affecting a minority of patients, was highest in Naas and lowest in Beaumont and Cavan.
The report does not look at death rates that occur outside of hospital within 30 days.
The report also looked at the rate of caesarean sections in hospitals across the country.
The hospitals with the highest rates of C-section are St Luke's in Kilkenny with 35.4 per 100 births, Mayo General and Galway University.
The lowest are at Sligo General at 21 per 100 births, Wexford General and the National Maternity Hospital Holles Street.
Dr Holohan said this cannot be explained by complications in pregnancy alone and is also likely to be linked to practice.
Cork University Hospital did 66pc of hip fracture operations within two days of admissions but it was at 95pc for St Vincent's in Dublin and Mayo General.
Patients with COPD, including emphysema, are most likely to be hospitalised in Offaly and least likely in Kerry.
Hospitalisation for asthma is highest in Longford and lowest in Monaghan.
