Cause of death
The Primary Care Mortality Database (PCMD) holds records of the underlying cause for each death. This is based on an international classification of diseases (the International Statistical Classification of Diseases and Related Health Problems 10th Revision, ICD-10, World Health Organization, 2016) which identifies the medical condition judged to be the underlying cause of death. Underlying cause of death can be defined as the disease or injury which initiated the train of morbid events leading directly to death or the circumstances of the accident or violence which produced the fatal injury.
The underlying cause may be a long-standing, chronic disease or disorder that predisposed the patient to later fatal complications. The diagram below shows the underlying cause of death for deaths registered in 2014 in the NHS Coastal West Sussex CCG area. The size of each bubble represents the relative number of deaths.
In 2014, the biggest underlying cause of death was disease of the circulatory system (1,670 deaths, 27.7% of all deaths in the CCG) which includes deaths caused by stroke (451 deaths, 7.5% of all deaths), chronic ischaemic heart disease (450 deaths, 7.5% of all deaths), and myocardial infarction (188 deaths, 3.1% of deaths).
