Quality health care, information and education on health, and quality of life are part of the realization of basic human needs and rights and are altogether based on adequate communication. From an early age, when we rely on our own speech and when we are expected to be independent in performing our basic activities, we adopt a model to deal with various health and other difficulties. Making the right diagnosis and solving a health problem is difficult if the healthcare provider does not receive the necessary information from the patient. This problem also diminishes the trust in the patient - health care professional relationship, and it is well known that mutual trust is important while cooperating on a project called "health preservation". Deaf and deaf-blind people are also faced with the problem of communication barrier in achieving health care in Croatia. Language is the product of culture, and so the culture of the deaf and deaf-blind has introduced its own sign language. As there is no unique spoken language, deaf people of every nation have its own sign language. Inadequate education of health personnel on the subject of the Croatian sign language as the mother tongue of the deaf and deaf - blind in the Republic of Croatia, as well as on other appropriate ways of communication with persons with impaired audio - visual system, contributes to the superficial health treatment and consequently social isolation of this group of Croatian citizens. Although, by law (Health Care Act, Patient Rights Protection Act, United Nations Convention on the Rights of Persons with Disabilities), deaf and deaf-blind people are entitled to the same quality of care as hearing persons, the practice shows a different reality. Deaf and deaf-blind people remain those no one cares about because they do not know how. What appears to the hearing person to be progress and relief in the technical part of the hospital system - notifications, educational materials, infrastructure, lighting, communication channels (Internet, telephone ...), to the deaf and deafblind person can be a problem and a barrier. However, with some goodwill, effort and dedication, this barrier can be removed, and the quality of life of one, not so small group, greatly improved.
