Telemedicine systems handle sensitive data that must operate on channels that can guarantee security and privacy of the information. In any system for the practice of telemedicine, the value of the information transmitted depends on its quality, representa- tion and reliability. In these critical systems, all data with questionable quality, representa- tion or reliability are worse than worthless because they could lead to medical errors and consequent risks. Communications among different systems can be ensured through standards for data storage and communication. Not only will this change the way medical knowledge is applied, it will also change the way that knowledge itself is pro- duced. Applying data-mining techniques to large databases of medical signals can generate huge amounts of information and lead to a new strategy for formulating hypotheses to be tested with the scienti¿c method. It is even reasonable to expect that these analyses might reveal systematic alterations in one or more signals before the onset of an event .

Our society requires changes – radical changes – that place the organisational apparatus of the health care system in a critical position. Public opinion, as well as the opinion of medical professionals, reÀects doubts concerning the ability of physicians to preserve their current role in serving patients. The term profes- sionalism is frequently found in the medical literature and in debates about how to obtain the best organisation of health care systems. Although there is no consensus regarding the de¿nition of professionalism, the term is closely related to the moral principles and stan- dards of care, handed down from generation to generation, that make up the foundations of the medical profession [1, 2]. Renewal of the medical profession entails improvements in the quality of professional attributes related to ethics and morality, to clinical practice based on evidence and to stan- dards for medical care and the use of new technologies. It also involves improvements in monitoring the quality of outcome, acquisition of knowledge and use of such knowledge through the observance of the Hippocratic Oath. Along the same line, it involves improve- ments in monitoring clinical research conducted for the sole purpose of helping patients. The correct application of all these elements and the presence of a solid and dynamic pro- cess of continuing medical education and specialisation represent the one way of renewing the medical profession. Lubahan de¿ned it, the term professionalism is “the image of the ethical and moral conduct of those who practice the medical profession” . In medicine, the term professionalism implies “good medical practice”, which derives from the long and demanding training process that the profession requires. The demand for a better de¿nition of professionalism in medicine is a result of signi¿cant changes within our society and a growing need to guarantee improved quality in community-based health care services. Thus, the term professionalism is being identi¿ed as the essence of humani- sation, competence and specialisation . Modi¿ed from  De¿nition That part of the system represented by healthcare professionals Role To pause; to allow for critical-thinking skills Goal To do the best for patients; patient safety; professional performance Bion and co-workers recently focused on the importance of human factors in managing critically ill patients . The analysis of human factors provides a useful framework in which to understand and rectify unreliability and causes of errors, in particular, in complex systems such as the critical care setting. Human factors inÀuence performance as concerns the task, the individual and the organisation or system. By de¿nition, professionalism indicates a crucial concept concern- ing the contract between medicine and society (Table 30. In this scenario we express our personal point of view on medical professionalism according to physicians’ specialty, practice set- ting and pay-for-performance trials . Professionalism, which is fundamental to medical practice, must be thought of explic- itly. It is the basis of the relationship between medicine and society, which most observers call a social contract. The social contract serves as the basis for society’s expectations of medicine and medicine’s expectations of society. It therefore directly inÀuences pro- fessionalism, considering that we live in the era of commercialism, consumerism, bu- reaucratisation and industrialisation . When we think of profes- sionalism, it should be related to different cultures and their social contracts, respecting local customs and values . A decreased public trust in all professions has brought increased attention to medical professionalism; it relates to those skills, attitudes and behaviours that people have come to expect from individuals during the practice of a profession and includes several concepts, such as maintenance of competence, ethical behaviour, integrity, honesty, relationships, responsibility, reliability, altruism, caring and compassion, service to others, adherence to professional codes, justice, respect for others, self-regulation, scienti¿c knowledge, excel- lence, scholarship and leadership. There are no codes in the physician charter of medical professionalism  concerning pay-for-performance service. Health care systems are regulated to support the health care needs to a target popula- tion. In some countries, health care system planning is delivered among market participants, whereas in others, planning is made more centrally among governments, trade unions, charities, religious or other coordinated bodies to delivery planned health care services targeted to the populations they serve. It seems a very dif¿cult task comparing different organisations of health care systems, resource allocation and the modality to assure a horizontal and extra salary to improve the quality of care and outcome while reducing costs at the same 30 Professionalism, Quality of Care and Pay-for-Performance Services 351 time. However, health care planning has often been evolutionary rather than revolution- ary. The goals set by health care systems, according to the World Health Organization , are good health responsiveness to the expectations of the population and fair ¿nancial contribution. Duckett proposed a two-dimensional approach to evaluation of health care systems: quality, effectiveness and acceptability on one dimension, and equity on the other . Health care providers are trained professionals, working as self-employed individuals or as employees within an organisation – either a for-pro¿t corporation, a nonpro¿t company, a government entity or a charitable organisation. Examples of health care providers are doctors and nurses, paramedics, dentists, medical laboratory personnel, specialist thera- pists, psychologists, pharmacists, chiropractors and optometrists. There are generally ¿ve primary methods of funding health care systems [10–12]: 1. Advances towards improving the standard of care represent a real challenge in health care system management.
These studies have used cognitive measures such as memory tests and reaction time tests to imply the attentional demands of postural con- trol discount levitra soft 20 mg line erectile dysfunction kegel. More specifically buy levitra soft 20 mg overnight delivery erectile dysfunction over 75, there is a progressive increase in the atten- tional demands when moving from sitting to standing to walking (80). Other studies have used more typical postural measures to assess the at- tentional demands of postural control. Results similarly suggest a decline in postural stability associated with demanding cognitive tasks (84, 85, 86). Dual task interference on postural control can be observed in Parkin- sonian patients during performance of cognitive as well as motor tasks (87); the balance deterioration during dual task performance was signifi- cantly enhanced in patients with history of prior falls. Simultaneously, the tensor fasciae latae is inhibit- ed on the stance limb and activated on the swing limb. This pattern would increase the swing hip abductor moment and decrease the stance hip ab- ductor moment, resulting in a momentary loading of the swing limb and unloading of the stance limb. After gait initiation and when walking in normal conditions (no actu- al constraints), adult subjects exhibit a particular stable gait pattern, which is very reproducible from stride to stride, trial to trial but also over days. This rhythmic pattern implies the alternative, out of phase movement of the two legs. The gait cycle is the walking unit defined as the time interval between two successive identical body configurations, in general heel con- tact or heel strike. The gait cycle is divided in two phases: a stance phase – simple or double stance – and a swing phase. Stance and swing durations last about 60% and 40% of the cycle duration, respectively. With increase in body velocity, the stance duration substantially decreases whereas the swing du- ration hardly changes. As a consequence, the duration of the double stance phase significantly decreases with speed increment and even vanishes when switching from walking to running. The stride length linearly increas- es with speed increment until the speed of 2 m/s. Contrary to most mammals, which walk on four legs with the trunk roughly parallel to the ground, humans walk erect on two legs. A pen- dulum-like movement results, which converts ki- netic energy (Ec) into gravitational potential en- ergy (Ep), and inversely, thereby increasing gait efficiency (95, 96) (Fig. Interestingly, model- based studies demonstrated that the human biomechanical system shows a natural propen- sity for locomoting on earth (97). Pendulum-like bipedal locomotor movements are naturally un- movement of the body during stable, in particular in the medio-lateral plane gait. Balance of the trunk and swing leg about the supporting hip is maintained by an active hip abduction moment, which recognises the contribution of the passive accelerational moment, and counters a large destabilizing gravitational moment. Furthermore, bipedal compared to quadrupedal walking implies a dramatic re-organization of patterns of muscle action in order to propel the two-legged body forward while ensuring equilibrium. The motor pat- tern for quadrupedal locomotion consists in a basic alternative activation of extensor (stance) and flexor (swing) muscles. In turn, during human walking, a mixture of extensor and flexor muscles is activated, in particu- lar around the time of heel contact to stiffen the leg and roll over the stance foot. Throughout the remaining stance phase, soleus and gastrocnemii muscles near-solely contribute to producing the necessary energetic flux for propelling the body forward while ensuring ground support (97). Human locomotion along a straight path thus requires a complex se- quence of muscle activation to displace the two legs and the body forward while maintaining balance. However, goal-directed locomotion, such as en- countered in everyday life, often requires steering along curved paths. The inherently unstable bipedal gait becomes critical during curve-walking, as shown by turning difficulties in aged or diseased people (102, 103). Left graph: the horizontal distance between the feet and the body centre of mass changes during curve-walking. The distance decreases for the inner foot (grey symbols) and increases for the outer foot (open symbols), as a function of the curve tightness (change in heading). Right graph: the more tight is the curved trajectory, the larger is the path cov- ered by the outer foot with respect to the inner one. In addition, many temporal and spatial features of the movement of the inner and outer legs become asymmetric. Turn-related adaptations of gait parameters include ever-increasing diver- gences in stance duration, stride length, and foot rotations between the in- ner and outer leg (106), and are mirrored in limb-dependent tuning of mus- cle activity patterns (107). Implementation of a curve trajectory in walking humans thus requires the central nervous system to substantially accom- modate gait characteristics to curve tightness in order to fulfil complex bal- ance and propulsion requirements. Curve-walking may thus provide the ap- propriate context for clinical assessment of gait disorders (108). Neural control of locomotion Neural organisation of the act of progression is based on an interac- tion between subtle supraspinal regulation and basic central and periph- eral elements. Pattern is used in a broad sense to indicate alternating activity in groups of flexors and extensors. After gait initiation, afferents deliver movement-related information to spinal and supraspinal levels. The second role is a tim- ing function (phase-dependent modu- lation) whereby the sensory feedback provides information to ensure that the motor output is appropriate for the biomechanical state of the moving body part in terms of position, direc- tion of movement, and force.

In particular, ing location, the Ib inhibition turns into the brainstem neural centres and cere- excitation, and the Ia excitation is being bellum activate the spinal locomotor depressed by presynaptic inhibition. Cortical structures control skilled locomotion when environmental constraints require subtle adaptation of lower limb trajectory (111). Despite this tripartite organisa- tion of the walking system has clearly been demonstrated in vertebrates, no conclusive demonstration of such a control scheme has been provided in humans so far (112). Nevertheless, rhythmic activity is very rare after complete transection of the spinal cord (115). Afferent stimulation or neurotransmitter injection has to be pro- vided to the spinal cord to elicit stepping. By varying the level of transection of the neural ax- is, it was shown that the region for initiation of locomotion is located in the brain stem, at supraspinal level (117). There are clinical studies sug- gesting the existence of similar areas in adult humans (118). Influence of sensory afferent input on locomotor activity Results of studies involving deafferentation and paralysis unequivo- cally demonstrate that the nervous system in mammals is capable of gen- erating rhythmic motor output in the absence of peripheral feedback (119). In humans, the question of the specific role of the various sensory modalities in the reflex control of locomotion is still open: for example, functional loss of leg afferent fibres due to peripheral neuropathy does not always lead to major alteration in the gait pattern. Vibratory tendon stimulation is known to selectively recruit spindle primary afferent fibres (see above): vibration of soleus muscle would therefore disturb organisa- tion and execution of walking, especially if spindles fire continuously and subjects are blindfolded. But vibration induces only minor changes in du- ration and length of stance and swing phase, and on speed of walking and kinematics of lower limb segments. This paucity of effects is at variance with the perception of the subjects, who report illusion of leg stiffness and gait imbalance, as well as with the disturbing effects of vibration on qui- et stance.
