Variations in health identified by indicators such as infant mortality rate, life expectancy which are associated with socio-economic status and other determinants.
Health Needs Assessment
A systematic process for determining and addressing health needs, or "gaps" between current conditions and desired conditions or "wants". The discrepancy between the current condition and wanted condition must be measured to appropriately identify the need. The need can be a desire to improve current performance or to correct a deficiency.
Health Overview and Scrutiny Committee
Committee that looks at the work of the clinical commissioning groups and National Health Service (NHS) trusts and the local area team of NHS England. It acts as a 'critical friend' by suggesting ways that health related services might be improved.
Health Protection Agency
National agency that provides health protection specialist advice and leadership.
Health Survey for England
A statistical survey which is conducted annually in order to collect information concerning health and health-related behaviour of people living in private households in England.
Healthcare Associated Infection
Infections that are associated with admission to hospital or as a result of healthcare interventions in other healthcare facilities, to a patient or healthcare professional.
Healthcare Resource Groups
A grouping consisting of patient events that have been judged to consume a similar level of resource. For example, there are a number of different knee-related procedures that all require similar levels of resource; they may all be assigned to one HRG.
Heatherwood and Wexham Park Hospitals
Is an infection of the liver caused by a virus. It can be transmitted by sexual contact, shared needles, or contaminated blood products and is much easier to get than HIV, and can cause permanent liver disease and cancer. Most people have no obvious symptoms, and there is no known cure.
Describes a form of immunity that occurs when the vaccination of a significant portion of a population (or herd) provides a measure of protection for individuals who have not developed immunity. Herd immunity theory proposes that, in contagious diseases that are transmitted from individual to individual, chains of infection are likely to be disrupted when large numbers of a population are immune or less susceptible to the disease. The greater the proportion of individuals who are resistant, the smaller the probability that a susceptible individual will come into contact with an infectious individual.
Hospital Episode Statistics
A data warehouse containing details of all admissions to, and treatments in NHS hospitals in England.
Hospital Standardised Mortality Ratio
The number of deaths occurring in hospital as a percentage of the expected number of deaths (based on national averages and patient characteristics).
The Health Survey for England (HSE) is a series of annual surveys about the health of people in England, beginning in 1991. Each year the Health Survey for England focuses on a different demographic group and looks at such health indicators as cardio-vascular disease, physical activity, eating habits, oral health, accidents and asthma.
Human Immunodeficiency Virus
A lentivirus (slowly replicating retrovirus) that causes acquired immunodeficiency syndrome (AIDS), a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.
The name for a group of related viruses, some of which occur on the cervix and are risk factors for cervical cancer.
