## 4 Discussion  
Some authors date the beginnings of telemedicine to the 19 th century [51]. A milestone is considered to be the establishment of the microwave video network that linked Massachusetts General Hospital and Boston's Logan Airport by [PERSON] and several other physicians in 1968. Terrestrial telephony in Poland (Warsaw) began operating on 13 July 1882 and was launched by the Bell International Telephone Company. A milestone in the development of telemedicine in Poland was the remote transmission of an electrocardiogram. It was carried out by Professors [PERSON] and [PERSON] over a distance of about 500 m in Lviv before World War II in 1935 [52]. A more comprehensive introduction of telemedicine solutions in Poland had to wait until the early 1990s [4]. In the 1990s, the first frequencies for mobile networks were launched in Poland [23]. Today, the number of telephones per capita has increased to approximately 1.36 per person. In addition to the telecommunications infrastructure, an important background factor for the development of telemedicine is the emergence of very influential organizations and initiatives focused on telemedicine, often with a global dimension, including the National Telemedicine Initiatives initiated by the National Medical Library (NLM) [53], the Telemedicine Information Exchange (TIE) [54], ATSP--Association of Telehealth Service Providers [55] and ATA--American Telemedicine Association [14; 56; 57]. The mechanism for financing projects and initiatives in telemedicine that was launched influenced the development of telemedicine in its current incarnation. In October 1996, NLM announced funding for 19 multi-year telemedicine projects to serve as models for assessing the impact of telemedicine on cost, quality and access to healthcare, evaluating dif \begin{table}

ferent approaches to ensuring the confidentiality of health data transmitted over electronic networks and testing emerging health data standards. The telemedicine projects awarded prioritized healthcare for the elderly, supported rural primary care physicians, supported newborn care facilities and provided health information to healthcare professionals in rural and urban areas. TIE is located in all countries that have adopted the principles of telemedicine and is a comprehensive, international, quality-filtered resource center for information on telemedicine, telehealth and related activities. It is supported and maintained by ATSP and provides a global e-health information exchange. ATSP is an international non-profit trade organization whose membership aims to improve healthcare through the development of the telehealth industry [56]. It was founded in 1996 by [PERSON], MD, in Portland, Oregon. The association strongly believes that telemedicine is a practical tool that can improve the distribution of healthcare services for the benefit of patients and service providers. ATA is an international leader in the promotion and advocacy of advanced remote medical technologies.
