Good and high-quality communication is a prerequisite for adequate health care. In the population of people with impaired hearing and sight, communication is the main obstacle in everyday life and also in the care of these people when they find themselves in the role of a patient in health institutions. Nurses and technicians are the ones who first establish contact with a patient upon admission to a health care institution, therefore basic knowledge in dealing with and approaching the aforementioned population is essential. In general, very few hearing people know Croatian sign language, and nurses and technicians who know it are exceptions in the health system. Communication problems are the most significant problems for people with deafness and deafblindness, which often leads to the isolation of these groups from society. Today, over 300 sign languages are known, which includes 70 million people worldwide who use them. All sign languages include hand, head and body movements and facial expressions. Communication is the tool that most shows respect for the patient's dignity, and nurses and technicians use it to show and make it known how interested they are in their needs and problems. The extensiveness and demandingness of the nursing work does not favor this. Working under pressure, high expectations and an ever-increasing volume of work leads to a lack of time for communication with all patients, which is precisely the key to good healthcare practice. For patients with sensory impairments, it is necessary to invest additional time to establish communication in order for the transfer of information to reach a satisfactory level, which is one of the pressing problems in a busy healthcare system. All of these are problems that healthcare workers encounter when working with the aforementioned groups of patients, and they could be eliminated with adequate education. The number of people with disabilities is increasing every day, and this increase is particularly visible in the last 40 years or so. On the other hand, according to estimates by the World Health Organization, by 2050, every tenth person will have hearing loss. Croatian sign language is the original language of the community of people with deafness and deafblindness in the Republic of Croatia, it has its own grammar and is independent of the spoken standard Croatian language, but it is not the only means of communication used by this group of people with disabilities. It is known that the prevalence of deafblindness increases with age, therefore it is increasingly becoming a problem of geriatric care. Unsatisfied needs and incorrect access to people with deafblindness in homes for the elderly and infirm are not only a big problem for the community of people with deafblindness, but also for the education system of health professionals.
