Social Medicine and Health Care Organization as a science

Social Medicine and Health Care Organization as a science

Friedrich Engels (1820-1895)Called attention to the health of the

working class

Rudolf Ludwig Karl Virchow (1821-1902)the “Father” of Social Medicine

Those measures can be divided into 2 groups:

• -measures against the diseases;

• -measures aimed at improving health.

“The physician is the natural attorney (advocate) for the poor.”

Before the beginning of the 20th century 3 ways of health protection

were formed:

• with help of state measures(the promulgation of different medical and social work);

• with help of social measures;

• with help of medical insurance.

Medicine is a social science,

and politics nothing but

medicine on a grand scale.

- R. Virchow, Die Medicinische Reform, 1848

“Social hygiene” studies interaction of social factors and human health including changing of need in medical aid with the purpose of making the rational economic system of civic health protection measures (K.Gargov, 1969).

Social medicine and organization of health protection

is a science about social conformity with human health and the ways of its improvement by rational organization of health protection.

The stages of development of statistical material are following:

• control /logical and technical/;

• enciphering /code/ of registered signs by numbers, letters of alphabet;

• lay-out of cards on groups for the subaccount or groupment;

• report of material;

• deduction of statistical criteria /indexes/, their graphic image.

There are two levels of medical service organizations in our independent state:

• a) Ukrainian Public Health Service;

• b) private doctors.

The fundamental task of modern system of health

protection in Ukraineis saving and strengthening of population

health, improvement of medicare qualities, and development of concrete medical and prophylactic measures, forms and methods of work of the specialized services.

WHO (World Health Organization) determines health as the state of complete social, biological and psychological prosperity, when functions of all organs and systems are balanced with an environment, absence of diseases, sick states or physical defects.

The most essential among indices:

• demographic (birth-rate, death rate, average life duration);

• physical development (functional and biological development, harmoniousness);

• morbidity (general, hospitalized, infectious); disability (primary and constant);

• state (immunity, resistance of the systems, activity of enzymes, etc.).

Risk factors are divided into 4 large groups:

• 1) way of live (smoking, wrong food. Abuse of alcohol, harmful work, stresses, hypodynamia, using of drugs, incomplete family or family with many children, hyperurbanization) - 51-52%;

• 2) environment (air, water, meal, radiation level, electromagnetic fields) - 20-21%;

• 3) biological factors (heredity, constitution, sex, age) - 19-20%;

• 4) medical factors (inoculation against infections, medical inspections, quality of medical treatment) - 8-9%.

Groups of health • 1 group - healthy (0-1 case of acute respiratory illness

per year);• 2 group - practically healthy (persons with the factors

of risk; no more than 2-3 cases of acute respirator illness per year);

• 3 group - patients with the compensated state (persons with chronic illnesses without complications; 4 and more cases of acute respirator illnesses per year);

• 4 group - patients with the subcompensated state (persons with complications of chronic illnesses during a year);

• 5 group - patients with the decompensated state (chronic patients in stage of decompensation).

Having worked out the general tendencies of main indices of population’s health the WHO defined the following criteria

which all countries are to aim at:

• 1. Availability of primary MSA;

• 2. The percentage of gross national product expended on the health protection, must be 7-8%; in our case it is 5% (more often 1-3%);

In total 1500 100.0

•3. Positive natural increase of population in all regions (now in many regions natural increase is negative);•4. Percent of children whose birth with weight 2500 grammas and less has to be no more than 3,5%;•5. The level of death rate of babies must not exceed 9 cases for 1000 born alive, and actually per year is within the limits of 12-15%;•6. Average life duration is not to be less than 75 years, and it actually is 67,8.

Data of demography is used in two basic directions:

• 1) Description of population for given time (quantity, composition, features) – this is statics of population;

• 2) Dynamics of population or its motion - it is description of population quantity change processes.
