Healthcare-associated infection (HAI) is an infection acquired in the hospital or other healthcare setting.
Examples include catheter-associated infections and HAP.
Hospital-acquired pneumonia (HAP) is an example of a nosocomial infection. HAP is a new pneumonia arising two or more days after admission to hospital.
Hospital-Based Complex Clinical Care (HBCCC) provides hospital care (nursing and medical input) for patients who cannot be looked after anywhere else due to their frailty and complexity. The medical input should involve consultant geriatrician input as well as day to day input which varies between facilities (some GP, some specialty or junior doctor).
Criterion for eligibility is "cannot be looked after anywhere else" as assessed by consultant geriatrician. Eligibility should be reviewed every three months, and patients who no longer meet the criterion should be moved on (usually nursing home).
The high-dependency unit (HDU) offers a level of care (Level 2) between ward-level (Level 1) and ICU-level (Level 3).
A HDU is for "patients needing single organ support (excluding mechanical ventilation) such as renal haemofiltration or ionotropes and invasive BP monitoring. They are staffed with one nurse to two patients." (reference).

HFpEF is heart failure with preserved ejection fraction.
Human immunodeficiency virus (HIV) damages cells in the immune system. Once acquired, HIV persists for life. There is no cure, but antiretroviral drugs can control infection and stop transmission to others. HIV can be transmitted in a number of ways, all of which are preventable.
HIV can lead to acquired immune deficiency syndrome (AIDS).
