The dynamics of today's world requires every one of us to maintain, upgrade and refine our knowledge and skills lifelong. For the nurses whose profession is regulated in the EU member states, as well in Bulgaria, continuing education is a key element of their professional development. One of the main objectives of the continuing professional education (CPE) is to contribute to the acquisition of new knowledge and skills in a way, appropriate to meet the needs of а present-day medical practice. The institution that organizes, coordinates, provides and registers continuing professional education of the health care professionals is Bulgarian Association of health professionals in nursing (BAHPN). There are different forms of professional educations – courses, congresses, conferences, seminars, ets. For estimation of the various forms of the continuing education in 2006 have been applied United Credit System (UCS), according to which for participation in each provided form credit points were given. The instrument for registration was the National Electronic Professional Register (NEPR).The aim of this study was to analyze retrospectively the trends in the development of continuing education of nurses in Bulgaria for a period from 2006 until the end of 2017. A database from NEPR with 86866 registered participations was used. Inclusion criterion included that health professionals were nurses, with or without registered CPE participations. The study employed retrospective analysis, documentary and statistical methods.The system of continuing professional education of the nurses in our country is an actively developing system that provides equal access and variety of forms of CPE, credited by BAHPN’s United Credit System. The most preferred form of CPE for the nurses was a traditional course. Participation in other forms of continuing education was under the expected levels and occupied a share of only 14.35% in the total structure of continuing education.The registered number of CPE participations for the observed period is a reason to designate nurses as "learning professionals". Despite the existence of some barriers to participation in continuing education, nurses accomplish their professional ethical commitment by actively building their knowledge and skills. The results of the survey revealed the need of measures to motivate nurses to participate more actively in the different forms of continuing education. Motivation could be achieved through interventions to provide support from the employer and colleagues as well as providing opportunities for sponsoring training and regulating a financial incentive to achieve higher competency.
