Sanatorium

SANATORIUM, a type of therapeutic and preventive institution, differing from hospitals in the composition of patients and methods of therapeutic and preventive impact. The contingent of S. consists mainly of convalescents after severe diseases and operations, as well as patients with not too advanced forms of certain chronic diseases. In S., natural healing factors, diet therapy, physiotherapy, physical culture, work therapy, sanatorium regime, etc. are widely applied; drug treatment, unlike in hospitals, is applied on a limited scale. However, under Soviet conditions, there is no major fundamental difference between S. and other inpatient institutions. The boundaries between the hospital and S. are gradually blurring, as all methods of hospital treatment are applied in S. when necessary. Historical data. Sanatoriums arose in the first half of the 19th century in Western Europe as highly qualified institutions intended for serving the wealthy classes of society. Only with the development of social insurance and national associations for the fight against tuberculosis did S. begin to open for the poor as well. But even now, most S. in the West are expensive institutions serving mainly wealthy people. In pre-revolutionary Russia, there were few S. During the war, the Union of Cities opened S. for convalescents after wounds and severe diseases of participants in active armies. The October Revolution gave a powerful impetus to the broad development of sanatorium construction, primarily at state resorts. In addition, former palaces, villas, dachas, and estates of landowners in various corners of the Soviet Union were adapted for S. and rest homes. This network proved to be clearly insufficient and poorly suited for the purposes of sanatorium work, and at present new construction of S. (mainly by social insurance bodies) is being carried out taking into account the latest achievements of medicine and technology. Network of S. The largest number of S. is concentrated at state resorts of Crimea, Caucasian mineral waters, Black Sea coast, etc. [see separate tables (art. 551-552)]. In addition to resort S., the USSR has a significant network of so-called local S., managed by health authorities, the All-Union Central Council of Trade Unions, and other departments and organizations. Moscow and Leningrad regions possess especially large and highly qualified networks of local S. The number of sanatorium beds increased from 26,372 in 1928 to 66,339 beds in 1932, the network of local S. reached 20,000 beds. In 1933, the network of sanatoriums of social insurance bodies alone reached 9,410 beds. Types of sanatoriums. S. at resorts are built according to the specialization of the resort and in accordance with the contingent of patients by type of disease. Thus, at balneological resorts, S. function specifically for gastroenterological patients and patients with metabolic diseases (Essentuki), cardiological (Kislovodsk), gynecological (Pyatigorsk), renal (Zheleznovodsk); at climatic resorts - tuberculosis S., sanatoriums for neurotics, etc. Local S. are usually differentiated by the nature of the diseases to be treated - tuberculosis, bone-tuberculosis, therapeutic, neuropsychiatric, as well as by the contingent of patients - children and for adults. (For indications for sanatorium treatment of tuberculosis patients - see Tuberculosis of the lungs.) In therapeutic S. (for patients with cardiovascular diseases, respiratory organs of non-tuberculous nature, digestive organs, movement organs, blood diseases), patients with temporary impairment of general or professional working capacity are directed. A special type of physiodietetic S. sets as its task the treatment of patients suffering from metabolic disorders and endocrine system diseases, diseases of the gastrointestinal tract and blood diseases, by diet, hormone therapy, physiotherapy, mineral waters and drug therapy. - Open neuropsychiatric sanatoriums can only admit those patients who in a relatively short time can fully or to a large extent restore their neuropsychological balance and professional working capacity. Organization of medical services. Depending on the profile and medical indications, the entire organization of medical work in S. is built - treatment methods, medical services, personnel, regime, nutrition, etc. Sanatoriums at resorts use general resort balneo-physiotherapy installations (bathhouses, mud therapy facilities, mineral water drinking pavilions, air-solariums, medical beaches, physio-mechanotherapy cabinets, etc.) and diagnostic institutions (laboratories, X-ray, electrocardiograph, etc.) for carrying out the treatment plan. Local S. usually have air-solariums, verandas for lying in the open air (Liegehalle), swimming pools, physiotherapy cabinets, water treatment facilities, laboratory and X-ray. Recently, the use of mud therapy in non-resort conditions (mud and peat), as well as the use of artificial mineral baths outside the resort - carbonic and hydrogen sulfide - has been introduced into sanatorium practice. Night S. are urban S. of open type and their task is to combine the treatment of the patient with continuing professional activities with the aim of preventing loss of working capacity. The patient during his stay in the night S., without being separated from production, is in hygienic housing conditions, receives additional nutrition, follows the established regime, undergoes sanitary-educational processing, acquires necessary hygienic skills and receives necessary treatment. In night S., in addition to those in need of preventive treatment methods without being separated from production, patients discharged from closed S. or hospitals are also directed with the aim of consolidating the effectiveness of inpatient treatment. On the other hand, the first group of patients undergoes observation with the aim of clarifying the diagnosis and, if necessary, directing them to closed treatment institutions and for special treatment with the aim of establishing the need to change profession, etc. Night S. are usually organized at hospitals, prophylactoriums, dispensaries. In the latter cases, they use the physiotherapeutic, diagnostic and other installations available in these institutions. Usually, male and female night sanatoriums are organized separately, or male and female groups alternate at certain intervals. Night sanatoriums are attached to specific enterprises, and individual shifts of patients are usually composed of workers from specific shops. Therefore, the regime of the night S., first of all, the hours of arrival and morning rising, vary depending on the working hours and shift work of the workers of this shop and enterprise. Management of S. is entrusted to chief physicians, the household-administrative work is carried out by the manager of the S. household. At present, at a number of resorts, managers (directors) of S. are administrators, to whom managers of the medical part of S. are appointed, responsible for the organization of treatment work and being chairmen of the so-called sanatorium treatment consultation, which includes the physicians of the S. The staff of S. varies depending on specialization and capacity. The staffing norms in S. (the number of patients per 1 member of staff) are as follows: Positions In S. at resorts and therapeutic local S. In S. for tuberculosis and severe patients Physician 40-50 25-30 16-18 20-40 40-50 35-40 18-20 10-12 20-25 40-50 Junior care personnel Sanatorium regime covers the entire daily routine of the patient; it should be built in accordance with the profile of the S. (different at drinking, mud, climatic resorts and local S.) and be strictly individualized. For the convenience of organizing the regime and monitoring it in S., several regime schemes are established, containing different ratios of rest and load (see Resorts, resorts of the USSR). Nutrition of patients in sanatoriums is under the supervision of a physician specially designated for this purpose. The total caloricity of food varies from 3,000 to 4,000 calories per day. In special sanatoriums, depending on their purpose, diet tables have been introduced, and the general management of diet nutrition is entrusted to a dietitian. Physical culture and sanitary-educational work. Physical culture in S. is applied in the broad sense of the word, starting with body hygiene, morning cold rubdowns, douches and showers, physical culture exercises, exercises for individual systems and organs, teaching proper breathing, walking, rest, and ending with all kinds of games, excursions, etc. The task of the treating physician - together with the physical culture physician or instructor - is to dose it depending on the severity of cases, age composition, profession, etc., and to choose the most suitable complex, establishing a gradual increase in physical culture exercises. Cultural-sanitary-educational work should be dosed along with other treatment methods, for which schemes for the assignment of cultural-sanitary-educational work are established, providing for both quantity and duration. - A completely new and therefore very difficult, but also extremely important task is the introduction of the element of dosed therapeutic labor into the everyday life of S., which beneficially affects the mental state of patients.

Work therapy, by placing certain demands on the body's load, serves as a training and strengthening medium, helping the attending physician to precisely control the patient's work capacity, and facilitates the patient's transition to normal professional life. By instilling in the broad masses the concept of labor as a health-improving life factor, work therapy also has educational significance. Dispensary care of sanatorium patients. Referral of patients to S. is carried out by sanatorium selection commissions existing at large enterprises and medical-prophylactic institutions. Candidates to be sent to sanatoriums are identified by the attending physician at the place of residence or place of work of the patient during the course of daily observation and treatment. In the first instance, workers in the main branches of industry are directed to sanatoriums, with the allocation of places by factories and enterprises being determined by regional and provincial trade union councils in accordance with the directives of the All-Union Central Council of Trade Unions. The number of workers in S. averages around 70%, with the remaining places being provided to employees, students, disabled persons, family members of workers, etc. The sanatorium selection commission, in addition to medical indications, is also guided by the production value of the worker (shock work, Socialist competition), his living and domestic conditions, etc., when selecting candidates. Preparation of the patient for sanatorium-resort treatment (carrying out necessary analyses, sanitation of the oral cavity, removal of tonsils, etc.) is of very great importance, enhancing the effectiveness of treatment; no less important is consolidation of the achieved treatment results through examination of the patient by the attending physician of the outpatient clinic after the completion of sanatorium-resort treatment and, if necessary, the establishment of appropriate additional treatment (mainly physiotherapeutic), work and rest regimens, etc. (For the accounting of sanatorium treatment results - see Balneology.)

L. Goldfeid. The construction of sanatoriums in prerevolutionary Russia was a rare phenomenon. Even on the largest resorts, there were only a few adequately equipped sanatoriums, and most of them were organized during the imperialist war in connection with the need to treat sick and wounded officers. As the resort territories were liberated from White Guards and interventionists, extensive work was undertaken to adapt private property on the resorts for use as sanatoriums. Individual estates and palaces, hotels, mansions, and dachas were rebuilt into sanatoriums in accordance with a specific system of medical-sanitary and cultural-domestic service for the patient and vacationer. In the process and experience of this work, the basic requirements for the construction of Soviet sanatoriums, intended for the health improvement of the broad masses of workers of the Union, gradually took shape. The new sanatorium construction began somewhat later, as the old resources were developed, and received the greatest development in connection with the industrialization of the country and the collectivization of agriculture, which opened up the widest prospects for sanatorium-resort affairs as one of the links in the general system of cultural-domestic service for the working class. In this regard, the data on the development of new sanatorium construction in the Sochi-Matsesta resort area are characteristic. Here, during the 1932 construction season, about 3,500 sanatorium beds were under construction, which is more than 50% of the existing sanatorium fund. About 20 million rubles were allocated for the construction of new sanatoriums this year. The great development of sanatorium construction in the Caucasian Mineral Waters (especially in Kislovodsk) is also well known. - The rapid growth of industrial construction in various parts of our Union has led, along with the expansion of the sanatorium fund in resorts of all-Union importance, to the development of local sanatorium construction in the areas of new industrial centers and new construction sites. The new construction of sanatoriums in the USSR is characterized by a number of achievements. Already, examples of very successful resolution of the requirements for a Soviet sanatorium, both from the medical-organizational and architectural sides, can be cited. At the same time, the new sanatorium construction is often marred by a number of major shortcomings - until the very last time, there was still a great inconsistency in the principles and standards of design; the architectural design also often does not meet the constantly increasing cultural demands. In this regard, the work of the State Central Institute of Balneology in the field of planning, standardization, and typification of sanatorium construction (begun in 1931-32) is of great practical importance. The basic principles of organization and design standards are being scientifically investigated: 1) territory, 2) buildings and structures, 3) equipment. The territory of the sanatorium is of decisive importance in the organization of sanatorium service and should be the subject of special attention during the construction of the sanatorium. The selection of the site must ensure the unconditional fulfillment of a number of sanitary requirements, which are higher than in other populated areas, and must be in strict accordance with the purpose, volume, and type of the sanatorium to be built. One of the decisive factors in selecting the site are the climate and microclimate conditions (winds, temperature data, relative humidity, conditions of insolation and aeration). In a number of cases, the requirements for the most favorable microclimate conditions must be combined with the need to locate the sanatorium close to healing springs, the sea, or other healing factors. In any case, the sanatorium should be located in a healthy area on a well-drained site, favorable in terms of soil and orographic data for the implementation of the main elements of improvement, as well for the allocation of a special zone of mountain-sanitary protection (see). Special attention should be paid to the sufficient isolation of the sanatorium from populated areas, industrial enterprises, transport hubs, transit roads, as well as to the location of the territory on the windward side in relation to possible sources of air pollution. The organization of the territory is carried out by developing a general plan. On the general plan, the lands of the sanatorium and adjacent to it should be marked with the designation of the boundaries of the sanatorium and the mountain-sanitary protection zone, the topographical features of the area, lands of agricultural significance with the indication of the boundaries of individual plots. The plan should also show all artificial structures, road profiles, all residential and non-residential buildings (with subdivision by type of building materials), both existing and proposed for construction. The general plan of the sanatorium is a necessary and basic document in resolving issues related to the territory and is part of the planning project of this populated place and the area as a whole. The general plan is developed for a period of at least 15 years and provides not only for construction and expansion on this territory, but also for the sequence of work over time. The organization of the sanatorium territory must provide for a clear definition of individual districts (zones) and their functional connection with each other. The interdependence, size, and ratio of the sizes of individual zones must be determined in each specific case on the basis of special medical-organizational and technical-economic calculations, depending on the characteristics of this territory, the type, composition, and volume of the sanatorium, the accepted system of patient service organization, and on a resort - the connection of this sanatorium with the general resort economy, etc. In any case, the allocation of zones must be provided: 1) for the direct service of patients - medical and cultural-domestic, including special areas for physical culture, work processes, aero- and heliotherapy, passive rest (so-called 'quiet zone'), 2) economic-technical institutions, 3) housing for service personnel, 4) auxiliary agriculture, etc. At the same time, both proper isolation and the connection of individual zones with each other must be ensured. The size of the sanatorium territory, varying within wide limits depending on specific conditions, should nevertheless not be less than 250 m² per 1 bed for the zone of direct service to patients, so that the percentage of building development in this zone does not exceed 7-10% in two- or three-story construction. Green plantings are planned in close dependence on the general system of medical-prophylactic measures in the sanatorium. In addition to the tasks of prophylaxis and decorative design, green plantings should contribute to the replenishment of food supplies of the sanatorium (garden, vegetable garden, greenhouse, horticulture, etc.) and should also be adapted for the purposes of work therapy. The greening norm can be taken at 60-70% of the sanatorium territory. Green plantings should be developed as a unified system, connecting the sanatorium with the nearest green masses in order to ensure protection of the sanatorium from strong winds and other unfavorable climatic factors. Green areas should separate individual zones, without at the same time hindering the sufficient ventilation of the territory and proper insolation. - The optimal number of beds in a sanatorium for patients, as shown by research of the State Central Institute of Balneology, can be taken at 200-300. The construction of sanatoriums with more than 300 beds may be acceptable under special conditions, more than 500 beds usually does not find justification. The location of buildings on the site (with a correct system, see below) should ensure convenient communication between individual groups of premises, and the distances (so-called service radii) are established depending on the served contingents of patients and should not exceed 300 m. The orientation by cardinal points for the sleeping rooms of sanatoriums is most favorable to the southern half of the horizon, in particular to the southeast. Orientation to the southwest should be avoided (especially in the south), due to the significant overheating of rooms in the afternoon hours. For operating rooms, doctor's offices, kitchens, orientation to the northern half of the horizon is desirable. The gaps between buildings depend on their number of stories and should be set at no less than 40 m for long sides and no less than 10 m for ends; a setback of the building from the boundaries of the site should also be provided, guaranteeing the building from dust and noise. The kitchen and other domestic and technical premises in relation to the housing should be located on the leeward side, taking into account the prevailing winds in the summer. When designing the entire sanatorium in one building, the entrance to the dining room should be located mainly in the direction of the sleeping buildings with the calculation to avoid patients passing by the entrance to the kitchen and the adjacent territory of the domestic courtyard. The windows of the kitchen and kitchen entrances should not be located opposite the premises for cultural-domestic and medical-diagnostic service of patients and vacationers.

The paths for kitchen and courtyard communications must be coordinated with the system of roads for domestic purposes and are designed to allow for the delivery of products, removal of garbage, refuse, etc., bypassing the buildings directly serving patients. The composition and volume of rooms in a sanatorium can be characterized approximately by the following data (in m³) (p. 553):

the territory of the sanatorium. On average for approximate calculations, the number of service population with families can be taken as 1.3-1.5 residents per bed, which requires 80 to 100 m³ of premises (including premises for cultural and domestic service) per sanatorium bed. Premises intended for the domestic and technical service of the sanatorium constitute about 15-20 m³ per bed (this includes warehouses, bathhouse, laundry, transport premises). The complete finished sanatorium includes the following groups of premises: A. Administrative premises with reception and isolation ward (fig. 1 and 2). B. Sleeping premises (fig. 3). C. Treatment premises (fig. 4). D. Premises for cultural and domestic service of patients (fig. 5-7). E. Premises of a cultural and health-improving nature. F. Service-domestic premises and housing for personnel. The first 5 groups of premises (A, B, C, D, E) can be located either in one building (sometimes two or more buildings connected to each other by covered warm passages, i.e. in one block) or in separate buildings located on the site in a certain way (the so-called pavilion type). The first type, i.e. sanatorium in one block, can be recommended for small sanatoriums - not more than 150-200 beds, operating year-round and intended for patients with limited mobility. In all other cases, the pavilion type can be recommended. The choice between these two types of sanatoriums depends, of course, on a number of local conditions - size of the site, its relief, main building materials, etc. The advantages of the first type - greater compactness of the sanatorium, greater ease of serving patients, no need to duplicate auxiliary premises (e.g. vestibules, cloakrooms), accessibility of all sanatorium premises without the need for outer clothing, which is especially important in rainy and cold weather. The pavilion type lacks these advantages, but it allows for better placement of patients, eliminates their overcrowding and the associated noise in the sanatorium, and allows for better use of the territory. In the first type of sanatorium, usually one vestibule with cloakroom (in the north also with a boot dryer) is built, designed for all the beds in the sanatorium, service personnel and possible visitors. In the second, pavilion type, vestibules are provided in each building and are designed for the maximum possible simultaneous occupancy. The area of vestibules and cloakrooms in sleeping premises is determined by somewhat higher standards than usual (simultaneous use due to the regime). The composition and areas of individual sanatorium premises (all numbers, areas, etc. are given approximately in relation to a normal type sanatorium with 150-300 beds). Administrative premises with reception and isolation ward. The administrative part consists of an anteroom with cloakroom with a total area of 20-25 m², an office of 18-20 m², an accounting office and cash desk of 18-20 m², a post office and savings bank of 15 m²,

The width of corridors in these premises is provided at 1.8 m; the height of premises at 3.0-3.2 m. The total useful area of all premises (without auxiliary area - corridors) is between 2.3 and 3.2 m² per bed. Sleeping premises are built in 2, rarely in 3 and 4, floors (in the latter case an elevator is provided) and consist of bedroom wards, common use premises, auxiliary treatment, service and auxiliary premises. Bedroom-wards are built for 1, 2 and 4 beds. The ratio between the number of these wards varies for different sanatoriums. In some - general

type, for gastro-intestinal patients - four-bed wards may predominate, in others - for neurotics - on the contrary, one and two-bed wards. The number of patients placed in one-, two- and four-bed wards varies depending on the purpose of the sanatorium within the following limits: in one-bed wards - from 6 to 20%, in two-bed wards - from 30 to 80%, in four-bed wards - from 0 to 60%. The number of beds (patients) in one department averages 50 and varies depending on the purpose of the sanatorium and the workload of the doctor in it from 25-30 to 60. For greater convenience in patient placement, each department is divided into 2 groups (sections) with their own service premises, while all other premises are common for the entire department or even wing of the building. The area of a one-bed ward is provided at 9-10.5 m², of a two-bed ward at 13-15 m², of a four-bed ward at 24-26 m². Wards are oriented to the southern half of the horizon - the closer to the south, the more one should avoid orienting the wards to the southwest. Types of wards are shown in fig. 8. Common use premises serve for rest and daytime stay of patients. In each department, 2 rooms with a total area of 45-50 m² and one smoking room (where it is not contraindicated) of 15-20 m² are provided.-Auxiliary treatment premises. In each department pre

Toilets are provided at 2 per department at the rate of 1 toilet for every 8 beds; in men's toilets, in addition, urinals are provided, in women's toilets - bidets; next to one of the toilets, sometimes a room of 6-8 m² for enemas and for storing items for the sanitary-hygienic care of patients is placed. Washrooms are also provided at 2 per department at the rate of 1 faucet for every 5 beds and one foot bath for every 10-15 beds; next to each washroom, rooms for cleaning clothes and footwear in 8-10 m² are provided;

Figure 8. -I-IV-types of rooms: 1-bed; 2-bedside table; 3-table; I-chair; 5-closet. Balconies are desirable for these rooms. A bathroom is provided for one ward (depending on local conditions, 1 or 2 bathtubs). A doctor's duty room of 9-10 m² is provided in one of the wards for the entire S. A nurse's duty room of 9-10 m² is provided for each building or wing of a building (on average for every 100 patients). A nurse's aide duty room is provided in each ward and consists of 3 parts: 1) the duty room proper, 2) for heating water, food, etc., and 3) for storing cleaning items, small equipment, etc.; the total area of the entire room is 22-26 m² on the upper floors and 30-36 m² on the ground floor (in the latter, a room for collecting dirty linen from all floors and an exit from this room to the outside are also provided). In individual cases, with a large number of bedridden patients, a buffet of 8-10 m² is also provided for each building or wing of a building. Auxiliary rooms. Corridors, depending on local conditions, possible and desirable orientation of the building and its individual rooms, are built on one or both sides. With two-sided construction of corridors, the latter is allowed within up to 60% of their length. The width of corridors is taken as 2-2.5 m. The staircase is usually located between two wards or groups of rooms. In front of the doctor's office and treatment room, corridors are usually somewhat widened, forming small waiting rooms. Depending on the type of S. and the adopted heating and ventilation system, each building also provides rooms for a boiler room, fuel storage, ventilation chambers, etc. Terraces, verandas, and balconies for general use are provided near sleeping quarters, and depending on the purpose of the S. and local conditions, individual balconies or common verandas for therapeutic purposes (Liegehalle) are also provided; the latter are provided at a rate of 3.7-3.8 m² per bed. The total useful area of all rooms, depending on the type of S., its purpose, layout of rooms, and architectural solution, ranges from 17 to 21 m² per bed. The height of sleeping rooms is taken as 3.2-3.5 m; in auxiliary and some service rooms, this height can be reduced to 2.8 m. The total volume of a sleeping building, depending on its number of floors, height of rooms, and useful area, is about 80 m³ per bed. Treatment rooms constitute the medical center of the S., in which all treatment facilities, special doctor's offices, special diagnostic offices, laboratories, pharmacy, and conference hall are located. These rooms are usually located on 2 floors: on the lower floor - water and mud treatment room, X-ray, operating room, most frequently visited patient offices, on the second floor - electro-light therapy room, laboratories, pharmacy, conference hall. The nomenclature and number of treatment facilities here depend more than in any other rooms on the purpose of the S., the contingent, and the number of patients in it. The treatment rooms include: head office of 15 m², dental office of 15 m², eye, also laryngological, office of 18-20 m², 2-3 consultant offices of 15 m² each, medical office of 15-18 m², conference hall (and medical library) of 30-50 m². Water and mud treatment department consisting of waiting rooms, changing rooms, rooms for baths, showers, mud treatment, poliotherapy, wraps, rest after procedures, and a number of service rooms (doctor's office, staff room, linen rooms, drying rooms, restrooms, storerooms, etc.). The area of this department depends on its throughput and ranges in S. in one building from 0.5 m² (in tuberculous S.) to 1.1 m² (in S. for nervous patients); in pavilion-type S. - from 0.6 m² (in tuberculous S.) to 1.8 m² (in S. for cardiovascular patients) per bed of S. Electro-light therapy department consisting of waiting rooms, rooms for electrical equipment and service rooms (doctor's office, staff rooms, restrooms, workshop, service room, rectifier room, etc.).
