1 Völker MiS Activ. The active Micro-Stimulation-System for bedsore prophylaxis, mobilisation, pain reduction and the promotion of perception.
2 Meanwhile, Micro-Stimulation is a tried-and-tested concept for institutional nursing as well, with exceptional success in, for example, bedsore prophylaxis to boot. Now, Völker has developed its active Micro- Stimulation-System, Völker MiS Activ, as an ideal completion, for bedsore therapy too. Only at Völker: Hospital beds with Völker MiS and MiS Activ. Two years ago, at the ALTENPFLEGE 2003 in Nuremberg, Völker introduced the Micro- Stimulation-System as a new undersuspension. This made available a nursing aid directly integrated into Völker hospital beds which supports and completes basal stimulation in an appropriate manner and thus contributes to bedsore prophylaxis. There has been a compelling positive response and now 9 out of 10 beds are delivered with Völker MiS. The Micro-Stimulation-Systems principle is primarily based upon the theoretic foundations of basal stimulation, the Bobath concept and kinaesthetics. Micro-Stimulation-Systems promote and maintain the patients own movements and their perception through feedback between them and the system itself, which characteristically consists of the butterfly spring technology. This feedback supports the perception of one s own body and thus stimulates a patient s own movements. This, in turn, guarantees physiological blood circulation in the skin, which prevents the development of pressure ulcers (bedsores) or provides the right conditions for the healing of such wounds. At the same time, the Völker MiS Micro-Stimulation-System also meets mobilisation, promotion of perception and pain reduction requirements. MiS has thus become firmly established as a nursing aid which supports and completes basal stimulation in an appropriate manner. The classical Thevo-Adapt has been used for bedsore and pain patients with huge success, and for the past two years so has the Völker Micro-Stimulation-System in institutional healthcare (see page 12). After the results of a scientific long-term study have now been made available (see page 14 ff), Völker decided also to introduce active Micro-Stimulation in healthcare and hospital beds see page18). This brochure contains various articles which will give you general information about Micro- Stimulation in detail, especially about Thevo- Activ, the Völker Micro-Stimulation-System MiS and MiS Activ. The articles are taken from various publications. They may thus be a wee bit repetitive in terms of contents, but this makes the individual articles more intelligible. They are thus reprints of the originals.

4 4 Andreas Fröhlich konzipiert die Basale Stimulation Originally, basal > stimulation was a concept developed by Professor > Andreas Fröhlich in 1975 for the personality promotion and development of physically and mentally handicapped children. The term basal means that we want to use the most simple and elementary possibilities to reach out to people, to get in touch with them. It also means that we revert to the basis, i.e. the foundation of all human action. Stimulation means: A severely handicapped person is offered something positive, something that encourages him to get in touch with other people and his environment. Within the framework of the concept of basal stimulation, which is also based upon developmental physiology and psychology (cf. Piaget > Bobath in particular), Fröhlich offered the children perception experiences for which they didn t need to fulfil any requirements and which go back to very early, mostly prenatal experiences: Feeling one s own body, experiencing to be in motion, spatial position changes or discovering one s inside through vibrations (somatic, vestibular, vibratory experiences); listening closely, watching closely, oral and olfactory experiences, grasping one s environment (acoustic, visual, oral and olfactory plus tactile experiences). A. Fröhlich and his staff have successfully discovered that children responded within the bounds of their possibilities and have thus been able to develop a form of elementary communication which accompanies the children during their experiences and promotes their skills. Christel Bienstein implements basal stimulation in nursing Professor > Christel Bienstein and > Andreas Fröhlich have jointly transferred the afore-mentioned basic ideas of their concept to the nursing of adults and discovered that basal stimulation can just as well be applied to seriously ill adults. They found, for example, that apallic and comatose patients feel the same basic need for perception, movement and communication, while only having impaired faculties of experiencing them and running a risk of further damages if not stimulated in a targeted fashion. Basal stimulation in nursing tries to provide such people with the known, elementary experiences of perception in order to accompany them during such experiences and to promote their capabilities. The target group are all people with impaired capabilities of perception, movement and communication, e.g.: Unconscious, artificially respired, disorientated, somnolent, skull-brain traumatised people; dying people; patients with hypoxic brain damage, Morbus Alzheimer, hemiplegic, apallic or comatose syndrome; patients with a very limited mobility; the disabled and premature babies as well. All these people have in common that they need to be physically close to people in order to perceive them, that they need the one nursing them to let them feel their environment in the most simple way, to enable them to change their position or move and who will also nurse and feed them (cf. Fröhlich 1998). A. Fröhlich: Basale Stimulation. Das Konzept Düsseldorf 1998 A. Fröhlich: Wahrnehmungsstörungen und Wahrnehmungsförderung Universitätsverlag Winter, 2005 C. Bienstein, A.

6 Thomashilfen (fig. Gunnar Thomas) develops Thevo. Heinrich Völker implements MiS in institutional healthcare. 6 At the end of the 1990s, > Thomashilfen used the concepts developed by Fröhlich and Bienstein for a new technological system, a > Micro- Stimulation-System, and called it > Thevo. The Micro-Stimulation-Systems principle is primarily based upon the theoretic foundations of basal stimulation, the Bobath concept and kinaesthetics. Micro-Stimulation-Systems promote and maintain the patients own movements and their perception through feedback between them and the system itself, which characteristically consists of the butterfly spring technology. This feedback supports the perception of one s own body and thus stimulates a patient s own movements. This, in turn, guarantees physiological blood circulation in the skin, which prevents the development of pressure ulcers (bedsores) or provides the right conditions for the healing of such wounds. If a human being has only a limited capability to move or perceive, he is no longer able to adequately respond to environmental stimuli. This lack of a patient s own movement is the reason for the development of pressure ulcers. A targeted therapeutic stimulation will promote the patient s perception and he is then able to move by himself, e.g. by shifting his weight. Here, > Thevo-Activ supports the therapeutically important somatic (physical) and vestibular stimulation. Micro-Stimulation s various modes of movement promote the physiological blood circulation in the affected areas or areas of risk. This microcirculation thus ensured supports the healing of the wound(s). > Völker is a licensee of > Thevo. While retaining the operating mode of Thevo, Völker, in a first step, developed the technical prerequisites for the use of a > Micro-Stimulation-System in institutional healthcare. The result is > Völker MiS. Since 2003, Völker healthcare and hospital beds have been equipped with this undersuspension, first optionally then as a standard feature, which is meanwhile demanded by almost all Völker customers at any rate. After the positive findings in a long-term study of the active system > Thevo-Activ, > Heinrich Völker decided to develop an active Micro- Stimulations-System for institutional healthcare, too. After one-and-a half-years, this work has now been concluded. This time was necessary to convert Thevo-Activ s drive to ensure an easy handling and a long service life when continuously operated under consideration of standards and guidelines and an inexpensive large-scale production. All experts have meanwhile recognised that while the high incidence of pressure ulcers has to be put down to a lack of mobility among patients, this mobility cannot really be achieved, not only for a lack of knowledge but primarily for a lack of available bedsore-prophylactic and therapeutic means. Since costs play an important role here, this can now be changed by using Völker MiS for bedsore prophylaxis and by simply exchanging it for Völker MiS Activ for bedsore therapy.

8 Experts standard bedsore prophylaxis and the ongoing bedsore problem Preamble to the > experts standard 8 The bedsore issue has been one of the most important ones in nursing journals, nursing training, advanced vocational training, meetings and conferences for several years now. As a rule, these articles, however, focus on bedsore therapy and/or wound management of such a chronic wound. Bedsore prophylaxis as the preventive measure against the development of bedsores is rarely an issue in German specialist publications. National and international healthcare research has also dealt with this problem for quite some time. Its findings have led to the first national > experts standard for bedsore prophylaxis. This represents traditional measures like a risk assessment on the basis of standardised scales and appropriate skincare but also includes new concepts for skilled nursing. Shearing forcereducing positioning and transfer techniques, which are thus kind to the tissue, promotion of the patients self-mobilisation and instructions and training for the nursing staff are the main items in these concepts for medical care for this group of patients. But it is the prevention of this painful illness, so very expensive for the cost bearer, which should be paid much more attention to in times of tighter budgets. The prevention of pressure ulcers has to be objective of all efforts in nursing. After all, according to experts almost all pressure ulcers could indeed be prevented. Nursing experts in out-patient and long-term care facilities, in domestic care, among cost bearers and healthcare science institutes and manufacturers of nursing aids and dressing material try to tackle the bedsore problem and provide solutions. The strategies on offer have to be innovative and sound in terms of healthcare science. It is > Thomashilfen and > Völker s objective to meet these high standards and to improve such patients medical care. With innovative ideas, intensive research and interdisciplinary development, these two companies are the ones to contact when it comes to anti-bedsore systems. The experts standards make for changed requirements for anti-bedsore systems. Pressure reduction and shearing-force minimisation are still qualities not to be done without, but they do no longer suffice. Effective anti-bedsore systems have to be able to maintain and promote a patient s own movements. And they should have a positive impact on his "conception of his own body and its perception in order to avoid any negative influence on nursing measures and the patient s condition. Since people in danger of developing pressure ulcers are found in all facilities of the healthcare system, the (present) experts standard addresses geriatric nurses, nurses and paediatric nurses. (...) The experts standard is based upon a comprehensive analysis of the available national and international literature primarily a research of randomised controlled studies and the practice expertise of the members of the expert working group. The precept and result criterion define the prevention of bedsores as the central objective, since such a development can, as a rule, be counteracted. Nonetheless, this objective cannot be attained for all groups of people. There are limitations for those people whose medical condition does not allow a consistent application of prophylactic measures (e.g. in life-threatening situations), requires other priorities (e.g. people in their terminal stage) or precludes the prophylactic measures efficacy (e.g. serious blood circulation dysfunctions, perhaps when centralising drugs have been administered). The (present) standard s design in terms of contents and forms (a short and definite precept, measurable structure, process and result criteria) is based upon the tried-andtested international structure also used in the European network. The selected priorities focus on central aspects in order to avoid the standard being fraught with general statements(...). The general objective is an individual care, which also takes into account the patient s/relatives needs, if need be. The foundations for such an approach in nursing are, above all, a theory-based application of the nursing process method including an evaluation of the nursing success; an orientation along the patient s/the affected person s physical, social, emotional and spiritual needs; a meaningful documentation of the nursing process as an important data base for quality measurement; cooperation with other healthcare professions. The experts standard for bedsore prophylaxis presented in the following is the final version, drawn up by the expert working group in coordination with the DNQP s steering committee after the consensus conference.

9 The experts standard bedsore prophylaxis in nursing. Struktur The qualified nurse Process The qualified nurse Result Precept: Every patient in danger of developing a bedsore receives a prophylactic treatment which will prevent the development of a bedsore. Reasons: A bedsore is one of the serious health risks run by patients/affected people in need of care or outside assistance. In view of the available knowledge on the extensive possibilities to prevent bedsores, the objective is a reduction to the minimum. It is of primary importance that qualified nursing staff ensure a systematic risk assessment, training of patients and affected people, mobility promotion, pressure reduction and a continual use of prophylactic measures. S1 has up-to-date knowledge of the development of bedsores and a risk assessment competence. S2 has a command of mobilising, positioning and transfer techniques kind to the skin and tissue. S3a has the competence to select appropriate pressurereducing aids. S3b has access to pressure-reducing aids (e.g. soft cushions and mattresses), special beds (e.g. aircushion beds) within 12 hours. S4 knows further appropriate intervention methods for bedsore prophylaxis deriving from the risk assessment besides mobility and promotion and pressure reduction. S5 has the skill, information and training material to instruct and advise the patients/affected people and their relatives on the promotion of self-mobility. S6 is employed in a facility which ensures that all staff participating in the nursing of patients/affected people know of the link between continual intervention and a successful prophylaxis. Information on the bedsore risk is transferred to external parties at all times. S7 has the competence to evaluate the efficacy of the prophylactic measures. P1 P2 P3 assesses the bedsore risk of all patients/affected people for which a risk cannot be excluded right at the beginning of the nursing process and then at intervals to be individually determined and also forthwith should there be any changes in mobility, activity and pressure and on the basis of a standardised assessment scale, e.g. by Braden, Waterlow or Norton, among other things. on the basis of an individual mobilising plan ensures immediate pressure relief through regular micro-movement. A low friction and shearing-force transfer promotes the patient s self-mobility as far as possible. uses the appropriate pressure-reducing aids if the patient s/the affected person s condition does not allow a sufficient mobility promotion and/or pressure relief. P4 on the basis of the risk assessment initiates further intervention methods for all identifiable risk factors, which may, for example, affect the maintenance and promotion of tissue tolerance. P5 P6 P7 explains the bedsore risk and the necessity of prophylactic measures and plans such with the patient/the affected person and his relatives. informs those involved in the care of patients/affected persons in danger of developing bedsores about the necessity of the continuation of the interventions (e.g. staff in doctor s practices, operation theatre and X-ray departments or transport services).. assesses the patient s/the affected person s skin condition at regular, individually determined intervals. R1 There is an up-to-date and systematic assessment of the bedsore risk. R2 There is an individual mobility plan. R3 The patient is put on a pressure-reducing surface adapted to his requirements forthwith, pressurereducing aids are used forthwith. R4 The implemented risk factor interventions are documented. R5 The patient/the affected person and his relatives now the reasons for the bedsore risk and the planned measures and cooperate on their implementation within the bounds of their possibilities. R6 All those involved in the patient s/the affected person s care know about the bedsore risk and the necessary measures. R7 The patient/the affected person does not suffer from bedsores. 9
10 Völker MiS and MiS Activ. Why they are so important for nursing. Heiko Heine Head of ProScript!, Völker Wörld Editor-in Chief The > experts standard bedsore prophylaxis in nursing (see also pages 8,9) was published by the DNQP in August One would expect a lot to have happened since then. After all, a huge range of anti-bedsore mattresses and various prophylactic systems is available. And any lying surface of hospital or healthcare beds featuring a small and flexible part is advertised as an effective preventive measure. This statement on bedsore prophylaxis by a major manufacturer s expert at an exhibition stand is thus no real surprise: "We refer our customers asking about this problem to our anti-bedsore mattresses. After all, you don t feel plastic suspension elements anyway!" 10 Nursing staff, willing to prevent bedsore, often feel unsure of themselfes, because of the amount of informations. And, let s face it, he is not totally wrong. In fact, irritating developments in nursing are certainly on the increase. And the incidence of bedsores has not gone down. It is all still about nipping it in the buds. Thus, the precept of the experts standard reads: "Every patient in danger of developing a bedsore receives a prophylactic treatment which will prevent the development of a bedsore. Nursing staff are able to do that because they are up-to-date on the development of bedsores and able to assess the risk (see experts standard S1). And according to the experts standard, nursing staff have also mastered mobilising, positioning and transfer techniques gentle to the skin and tissue (see experts standard S2) and have the competence to select suitable pressure-reducing aids available within 12 hours, e.g. air cushion beds (see experts standard S3a, b). And there is the rub. After all, it is not all about knowledge and competence but about the availability of such means and considerable expenditure, too. The measures required by the experts standard often fail for a lack of suitable aids. For prophylactic treatment has to be provided in accordance with an individual exercise plan. This includes immediate pressure relief through regular mobilisation of the patient, e.g. 30 laying, micromovement, low-friction and gravity transfer and, as far as possible, the patient s self- mobilisation. If the patient s condition does not allow sufficient mobilisation or pressure relief, suitable pressure-reducing aids have to be used. The result according to the experts standard: The patient is put on a pressure-reducing surface adapted to his requirements forthwith, pressure-reducing aids are used forthwith. A 100 per cent prevention of bedsores would require appropriate aids for 450,000 healthcare beds. People in danger of developing bedsores need an immediate prophylactic treatment, mobilisation above all, once the danger has been recognised. Insiders estimate the risk of developing bedsores in hospitals at 30 per cent, in geriatric
11 nursing homes at 50 per cent or more. There are about 500,000 beds in hospitals, and about 600,000 in nursing homes. In plain language, this means the initiation of appropriate measures and an availability of appropriate aids for 150,000 plus 300,000 beds, if 100 per cent of bedsores are supposed to be prevented. And with regard to hospitals we only speak of their number of beds, not of the annual number of about 4.5 m patients, out of the total of 15 m, in danger of developing bedsores. People responsible for bedsore management point out that rendering medical care and funding medical care are two sides of the same coin. While experience teaches us that money does not equal quality, we can also see that there is no such thing as a free quality lunch (> Heike Lubatsch, Dekubitusmanagement, Schlütersche, Hannover 2004). Bedsore therapy costs about Euro 3.2 bn p.a. And the costs are huge. But the exact figures are as hard to come by as exact data on the bedsore risk and incidence and reliable estimates. Stiftung Pflege (a healthcare foundation) estimates the costs for the German healthcare system to come in at at least Euro 3.2 bn. Bedsore management in hospitals is thus often a continuous struggle with the financial department. These examples indicate insufficient medical care: demands for lower rents for bedsore mattresses, orders being placed without any consideration of nursing criteria, the procurement of 20 foam pads and 25 foam mattresses for bedsore prophylaxis and 10 for bedsore therapy, an additional 200 positioning cushions, and all this for a 550-bed facility. Bedsores develop unexpectedly. They are already there when you see them. Bedsores arrive by stealth. The human body s weight exerts pressure on the lying surface which in turn exerts counterpressure on the affected area of the skin. A bedsore will develop if a person moves only insufficiently and the pressure thus caused damages the blood circulation in the tissue for too long. A clamping of the venous capillaries is enough to bring about this reduced blood circulation and lack of oxygen. The body responds by a warning pressure pain, which in mobile persons will trigger a change of posture and thus a relief of the compressed areas of skin. Small movements will suffice. But if someone is no longer able to perceive the pressure pain or to move on his own in response to that pain, the skin will remain compressed and waste products will build up in the tissue, which will then lead to acidosis. This, in turn, causes an outflow of water from the capillaries into the tissue. The oedema thus formed will grow the longer the pressure is being exerted. The increasingly reduced blood circulation causes the skin cells to die and a bedsore is formed. Why there is such a bedsore incidence. Bedsores are an avoidable ailment because there is sufficient support and knowledge available. The causes are a lack of treatment or an inadequate treatment and insufficient information for the patients, says Professor > Christel Bienstein. The NPUAP (National Pressure Ulcer Advisory Panel) even calls bedsores a national tragedy because they make the affected patients suffer while at the same time being avoidable. And all this despite the fact that both in Germany and the USA various prophylactic and therapeutic means, some even state-of-the-art, are available. According to experts, the fact that the incidence of bedsores is not reduced despite the broad range of therapeutic systems available is due to their complicated, but also their frequently incorrect handling. On the other hand, the original problem, insufficient movement of the patient, is not, or only to a small extent, addressed, even when it comes to hightech beds. Nip it in the bud. With the Völker Micro-Stimulation-System. Inspired by the process of professionalisation in German nursing, some nursing concepts developed which allowed a holistic view and care of patients. basal > stimulation developed by Professor > Andreas Fröhlich in 1975 was one of them. During the 1980s, this principle was applied to nursing by Professor > Christel Bienstein. At the end of the 1990s, Thomashilfen developed under consideration of basal stimulation, by > Bobath and including > kinaesthetic principles a mattress undersuspension which was called > Micro- Stimulation-System (see also page 6). In 2002, > Heinrich Völker developed this undersuspension into a laying system for bedsore prophylaxis in institutional care (see also page 6). As with all microstimulation systems, the basic idea was that movement is only likely to occur when there is prior sensory perception. These stimuli are processed by the central nervous system and turned into movement in response to the stimuli. This physical activity makes for permanent pressure alterations also among those regions of the H. Lubatsch: Dekubitusmanagement auf der Basis des Nationalen Expertenstandards Schlütersche/
