Konquistador – the modern incarnation of cinematic dreams Nicolas Cage, Dominic Sena cheer for the continuation of his greatest hits. His pile of German tuners Felge, taking the original fifth-generation Ford Mustang, Cervini body kit for 8000 euros, loud exhaust system with caps to the front of the rear wheels, KW suspension with adjustable ride height HLS, Brembo brakes and Schmidt wheels with tires Dunlop, the presence of which almost imperceptibly. The result was both the worst and the most drop dead face had ever seen on the Mustang.
Oddly enough, but the appearance of the blood stirring the car – only the desire of the guys from Felge show us his trademark 20-inch wheels Hause Schmidt Revolution.
In calculating the coefficients of extensive we are only dealing with one set of statistics and its composition. Most extensive coefficient is usually expressed as a percentage, much less – in parts per million and in fractions of a unit. Extensive computation technique is simple factors:
For example, in 2001 the number of all diseases of children in kindergarten was 205 cases, including 72 cases of enteritis. If you take all the cases of 100 children, and cases of enteritis diseases for x (X), the share of enteritis among all diseases of children in kindergarten will be:
As examples of the extensive coefficients used in medicine and health care, you can call the structure of morbidity of the population, the distribution of patients hospitalized for individual nosological forms, differential blood count, etc.
Keep in mind that extensive performance characteristics should be used for the composition of the population (a phenomenon Wednesday) at a given location at a given time. For dynamic comparisons, these figures are not suitable. Comparison of specific weights can be judged only on their sequence number in the structure (morbidity, mortality, etc.), but makes it impossible to talk about the frequency, the prevalence of this phenomenon. For this purpose, always need to know the number of environments in which the phenomenon takes place and to calculate the intensity ratios.
Intense coefficients characterize frequency (intensity level prevalence) conditions in the medium in which it occurs, and which is directly integrally connected for a certain period of time, usually one year.
In calculating the coefficients necessary intensive statistical knowledge two sets, one of which is medium, and the other – a phenomenon. Wednesday produces this phenomenon.
In the demographic and health statistics in the medical environment is often seen as the population in the calculation referred to it or that phenomenon, for example, the number of cases per year, the number of births per year, the number of deaths per year, etc. In the calculation of the infant (infant) mortality among newborns is the amount attributed to it and the number of deaths of children under the age of 1 year.
If the calculated fatality rate for tuberculosis, the media will be all TB patients, and the phenomenon – who died of tuberculosis.
The coefficients are calculated on the basis of intensity 100, 1000, 10000, 100000, etc. depending on the extent of the phenomenon. However, in practice there are generally accepted health care provision. Thus, the overall incidence of the birth rate, death rate, infant mortality is expressed in parts per million (% o), and the incidence of temporary disability is calculated per 100 employees, mortality, complication rates are expressed in%.
Technique for computing intensive factors as follows:
For example, in the “H” in 2001, the population aged 70-79 years were 9845 people, of that number died in the year 784. To calculate the mortality rate of people aged 70-79 years to compile and solve the following proportion:
The ratio describes the numerical ratio of the two, unrelated populations, matched only logically, in their content. These include such factors as the number of doctors and hospital beds per 1000 population, the number of different laboratory tests or the number of blood transfusions on 100 patients, etc.
By the method of calculating the coefficients of correlation coefficients are similar to the intense, although different with them on the merits.
Common intensity ratios (fertility, mortality, infant mortality, morbidity, and etc.) reflect the correct frequency phenomena when they are compared only if the compared sets of homogeneous composition. If they have a non-uniform age-sex composition or a professional, the difference in the severity of the disease, according to nosology forms go on other grounds, then focusing on the overall performance, comparing them, you can make a wrong conclusion about the trends of the phenomena and the true reasons for the difference of the compared sets of common indicators .
For example, the hospital mortality rate in the medical ward number 1 in the year was 3%, and medical ward number 2 in the same year – 6%. If you assess the activities of these offices by general indicators, it can be concluded about trouble at 2 medical ward. And if it is assumed that the composition treated in these compartments of different nosological entities or severity of diseases hospitalized, the most appropriate method of analysis is a special mapping coefficients calculated separately. For each group of patients with the same nosological forms or severity of diseases, so-called “age-specific . ”
Often, however, in a comparable set of observed conflicting data. Furthermore, even if the same pattern in all compared groups are not always convenient to use a set of indicators, and preferably for a single total score. In all such cases resort to the method of standardization, ie the elimination (eliminating) the effect of composition (structure) of the general populations, the final index.
