Psychiatry as a branch of medicine greatly differs from other branches regarding the fact that this is the only branch that applies forced therapeutic methods. Aggression is the act directed towards the other person or towards oneself and it can be verbal, physical or sexual. Aggressive behaviour is related to any kind of threatening behaviour, no matter whether the aggression was expressed verbally, shown physically or if there is a clear aggressive intention or physical behaviour which currently injures or harms the aggressive person, other persons or belongings. Towards the patient whose psychological condition seems to be followed by extreme agitation and aggression and who, by his behaviour, causes danger for himself and the environment, we apply protocol measures of one’s control in the form of constraining bands, fixation by magnetic belts, or by separation into an isolation room. Taking into consideration that there is not a scientifically-based argument for choosing one forced method as more competent than the others, its choice depends on cultural and traditional constitution of the society in which it is applied. Usage of physical force as an intervention in psychiatry dates back from the very beginning, that is from the conception of care for the mentally ill persons. It is still one of basic methods in psychiatric work. By its work a nurse has to protect patients’ and their interests, as well as themselves. By conducting measures and elaborated protocols unwanted situations and incidents which could result in worsening health condition and sometimes even death, are being prevented. Forcing measures should be used only when de-escalation was not successful, apropos when it is the only way for preventing aggressive behaviour. During the period of conducting procedure, medical staff takes care about security and respecting the patients’ rights and uses force just enough that is necessary to neutralize threatening behaviour. After applying forcing measures, in a standard procedure and with the presence of a department chief, it is necessary to analyse samples and to reconstruct the beginning of a conflict, early escalation signs, taken measures, potential errors and all the other circumstances. Therapist-patient relationship appeared to be a risk factor and protective factor in both increasing and decreasing risk. Creating supportive environment on a workplace can reduce aggression and psychological trauma, reduce sick leaves and enable worker to feel safe at work.
