NSW Admitted Patient Data and Admitted Patient, Emergency Department Attendance and Deaths Register (SAPHaRI). Centre for Epidemiology and Evidence, NSW Ministry of Health.
Only NSW residents are included. Rehabilitation episodes are excluded. Figures are based on where a person resides, rather than where they are treated. Hospital separations were classified using ICD-10-AM. Rates were age-adjusted using the Australian population as at 30 June 2001.
A recent policy change (PD2017_015) resulted in patients treated solely within the emergency department being excluded from this indicator report. Please note that a minority of patients being managed in short stay areas of emergency departments are still included. Further information is found in a paper in the HealthStatsPLUS Methods tab on this website.The figures for persons hospitalised were calculated from linked hospital records for the same individual for the same year. This allows for the calculation of the number of hospitalisations per person per year.
LL/UL 95%CI = lower and upper limits of the 95% confidence interval for the point estimate.
Records from the NSW Admitted Patient Data Collection were internally linked for the same patient to ascertain the number of persons hospitalised.
Record linkage was carried out by the Centre for Health Record Linkage (CHeReL) (www.cherel.org.au).
The CHeReL maintains a Master Linkage Key, which is a system of continuously updated links within and between core health-related datasets for NSW and the ACT, including the NSW Admitted Patient Data Collection, NSW Emergency Department Data Collection, NSW Perinatal Data Collection and NSW Notifiable Condition Information Management System .

This indicator uses principal diagnosis only.
• Circulatory diseases cause more than 15,000 deaths and 150,000 hospitalisations of NSW residents in each year. Coronary heart disease and atrial fibrillation and flutter contribute the most to these diseases' hospitalisation burden, followed by heart failure and strokes.
• Death rates, and numbers of deaths, from circulatory disease are consistently higher in males than in females. Death rates are higher in Inner regional, Outer regional and Remote areas of NSW than in Major cities.
• Death rates from all forms of circulatory disease have more than halved in the last twenty years after adjusting for population ageing. This is due to both:
• decreased incidence, associated with reductions in some risk factors, including smoking, saturated fats in the diet, and levels of blood pressure;
• increased survival, as a result of improvements in medical and surgical treatment and follow-up care.
• Coronary heart disease caused 5,928 deaths in 2017. Coronary heart disease was the principal reason for 46,602 hospitalisations in NSW in 2017-18.
• Stroke caused just over 2,803 deaths in NSW in 2017. Stroke was the principal reason for 13,093 hospitalisations in NSW in 2017-18.
• Heart failure was the underlying cause of 1,116 deaths in NSW in 2017 and was a contributing cause in many more. Heart failure was the principal reason for 17,543 hospitalisations in NSW in 2017-18.
• In the treatment of coronary heart disease, the number of percutaneous transluminal angioplasty (PCTA) procedures (with and without stents) first exceeded the number of the more invasive coronary artery bypass graft (CABG) procedures in 2000-01. More than 15,000 PCTAs were performed in 2017-18, more than three times as many as CABGs at around 4,000 procedures.
Cardiovascular (or circulatory) diseases comprise all diseases of the heart and blood vessels. Among these diseases, the four types responsible for the most deaths in NSW are: coronary heart disease (or ischaemic heart disease), stroke (or cerebrovascular disease), heart failure, and peripheral vascular disease. Other causes of death are cardiac arrhythmias (most notably atrial fibrillation), heart valve disorders, non-ischaemic cardiomyopathies, pulmonary embolism, and hypertensive renal and heart disease. Significant causes of morbidity include hypertension, deep vein thrombosis, haemorrhoids and varicose veins.
Cardiovascular diseases accounted for 14% of the total disease burden in Australia in 2015, second only to cancers. The burden from cardiovascular diseases was predominantly fatal (78.5%) with only 21.5% due to non-fatal burden. Coronary (ischaemic) heart disease ranked highest in total individual disease burden (6.9% of the total burden) and stroke ranked ninth highest (2.7% of the total disease burden).
Presently, cardiovascular diseases account for around 48,000 deaths in Australia (around 33-34% of all deaths), more than any other group of diseases. This proportion has been in decline since 1970, when nationally cardiovascular diseases were responsible for over half of all deaths.
The four major causes of death from cardiovascular disease share a number of behavioural risk factors (tobacco smoking, physical inactivity, poor diet, risky alcohol consumption) leading to physiological risk factors (high blood pressure, elevated blood lipids, diabetes mellitus, and overweight or obesity).

Circulatory diseases share many modifiable risk factors with other lifestyle-related chronic diseases such as type 2 diabetes. These include smoking, physical inactivity, poor diet, harmful alcohol consumption and being overweight. This means that strategies related to the prevention, early detection and optimal management of these risk factors will lead to better health outcomes for people with circulatory diseases and other lifestyle-related chronic diseases.
