Summary
The number of patients on renal replacement therapy (RRT) in the UK increased by 4% in 2010, with more patients on haemodialysis and transplants, but fewer on peritoneal dialysis. The average age of RRT patients also rose.
Area of Science:
- Nephrology
- Public Health
- Epidemiology
Background:
- Adult patients on renal replacement therapy (RRT) in the UK in 2010 are described.
- Data were collected from all 72 UK renal centers.
Purpose of the Study:
- To describe the demographics of prevalent RRT patients in the UK in 2010.
- To analyze cross-sectional and longitudinal data at center and national levels.
- To calculate age and gender standardized prevalence rates per million population per year.
Main Methods:
- Electronic data collection from all 72 UK renal centers.
- Cross-sectional and longitudinal analyses of prevalent RRT patients in 2010.
- Calculation of age and gender standardized prevalence rates per million population per year.
Main Results:
- 50,965 adult patients received RRT in the UK in 2010, with an overall prevalence of 832 pmp.
- RRT prevalence increased by ~4% annually; haemodialysis (HD) and transplant numbers rose, while peritoneal dialysis (PD) numbers fell.
- The most common diagnoses were glomerulonephritis (16.0%) and diabetes (14.9%). Transplantation was the most common modality (48%), followed by HD (44%) and PD (8%).
Conclusions:
- The populations on HD and transplantation continued to grow, while the PD population declined.
- Significant variations in RRT prevalence rates were observed at national, regional, and dialysis center levels.
- The average age of prevalent RRT patients increased by 4 years compared to a decade prior, impacting service planning and care equity.

01:52Regression Toward the Mean
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:23Assessment of Respiration
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...

Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.

01:12Relative Risk
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
