Insights

Canadian subarachnoid hemorrhage (SAH) admission and mortality rates are lower than previously reported. This study found a declining trend in SAH hospitalizations and in-hospital deaths in Canada from 2004 to 2015.

Area of Science:

  • Neurology
  • Public Health
  • Epidemiology

Background:

  • Subarachnoid hemorrhage (SAH) is a critical neurological condition with significant mortality.
  • Understanding recent trends in SAH is crucial for public health planning and resource allocation.

Purpose of the Study:

  • To evaluate current trends in subarachnoid hemorrhage (SAH) admission and mortality rates in Canada.
  • To analyze hospitalization rates and in-hospital mortality for SAH patients.

Main Methods:

  • Retrospective cross-sectional study design.
  • Utilized data from the Canadian Institute for Health Information (CIHI) from 2004 to 2015.
  • Calculated adjusted admission rates, in-hospital mortality rates, and discharge dispositions for SAH patients.

Main Results:

  • A total of 19,765 patients with subarachnoid hemorrhage (SAH) were identified between 2004 and 2015.
  • The annual SAH hospitalization rate was 6.34 per 100,000 person-years, showing a decline of -0.67% annually.
  • The in-hospital mortality rate for SAH was 21.5%.

Conclusions:

  • Canadian subarachnoid hemorrhage (SAH) admission and mortality rates are lower than previously documented.
  • A significant declining trend in SAH hospitalization and mortality rates was observed in Canada.

Magnetic Declination01:19

Magnetic Declination

Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...

Reaction Rate02:53

Reaction Rate

The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that consume or produce gaseous substances, for example, are conveniently determined by measuring changes in volume or pressure.
The mathematical representation of the change in the concentration of reactants and products, over time, is the rate...

Related Rates

When two or more physical quantities are linked by a single relationship, a change in one variable necessarily affects the others. This interdependence forms the basis of related rates analysis, which examines how different quantities change with respect to time. A classic physical example is an expanding balloon, where the size of the balloon changes continuously as air is added.For a hot air balloon, the inflated envelope is commonly idealized as a perfect sphere to simplify mathematical...

Measuring Reaction Rates

Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a chemical reaction. Optically active substances have the capability of rotating the plane of polarization of linearly polarized light passing through them—a feature called optical rotation. Optical activity is attributed to the molecular structure of substances. Normal monochromatic light is unpolarized and possesses oscillations of the electrical...
