Information Architecture of Estonian Personalised Medicine Pilot Project iii Executive summary Since completion of the first sequence of human genome in 2003, followed by a rapid decline in costs of sequencing technologies on one hand and acquisition of deeper knowledge about the genome function on the other, we are nearly there to embrace genomic data as a cost-effective component of routine health service. Several personalised medicine initiatives have been launched all around the world in recent years. Amongst them is an Estonian pilot project for implementing personalised medicine in health care on national scale, planned to start in autumn 2015. This document summarises the preliminary analysis about the current state and future needs for information architecture and data management aspects related to the gradual implementation of the national personalised medicine initiative in Estonia. In the overview section a comprehensive description is given about the current components of the existing IT infrastructure laying ground for executing the principles of personalised medicine in Estonia. Remarkable amount of health data is available in databases online that can be linked together thanks to Personal Identification Codes and technological stack of Estonian IT infrastructure (X- Road). Tissue samples of 5% of the population are collected and 2400 of them will be soon fully sequenced. Several research groups have been working on data acquisition, extraction and quality as well as developing new decision support algorithms. However, all these approaches can be handled as ad hoc solutions and do not form a full closed cycle from research to treatment to follow-up and research again. The automatic decision support, the vital part of personalised medicine, even without the genetic component, has not been used in practice in Estonia as of today. We describe some key components and issues of information system and data management in the context of personalised medicine: linking the data, managing the consents, security and privacy. The Pilot Project shall seek the right balance between the possible lack and excess of privacy, because any leakage of highly sensitive genomic information could raise opposition against the whole project, but on the other hand, an excess of privacy-related hurdles could radically slow down research. It seems reasonable to divide general personalised medicine process into five sub-processes based on their nature: the clinical activities and direct interaction with the patient, managing big personalised data, decision support, pseudonymisation and research. We enlist the functional requirements together with possible solution alternatives for each of them. We also describe four different specific use cases across all these sub-processes. We also propose a four-stage strategy for building necessary information architecture by expanding the system step by step. During each stage it is still possible to execute the full cycle of the personalised medicine process. One should start applying personalised medicine principles on gene donors of the Estonian Biobank (EGCUT), and then move step by step to the whole Estonian population. International experts agree that it is now the right time to start applying personalised medicine principles as the sequencing costs are dropping and there are already some existing evidence-based cost-effective use cases to work with. However, the full detailed execution of the information architecture, data sharing, research and development will be highly dependent of the involved organisations and structures. Expertise exists in Estonia due to strong research universities and teams close to these on one hand and the appropriate information management on the other hand. There must be appropriate organisational decisions to strengthen the current expertise and future continued long-term growth and commitments on the national level. The main question boils down to the team(s) that will develop and execute (in an appropriate R&D setting) the various decision support systems required for the automated data-driven personalised approaches in medicine. Information Architecture of Estonian Personalised Medicine Pilot Project iv Lühikokkuvõte Alates inimgenoomi esmakordsest sekveneerimisest 2003. aastal on sekveneerimistehnoloogiate hind tänaseks väga kiiresti lan- genud, jõudes 1000C täisgenoomi ning 50C üle miljoni SNP genotüpiseerimise eest. Samal ajal on oluliselt kasvanud teadmised genoomi funktsioonidest, geenide seostest haiguste põhjustega või kaudsete riskide hindamisega. Täisgenoomide sekveneerimi- se hind jätkab avatud turul langust, kuid meie teadmised ja kogemused kasvavad. Seetõttu oleme nüüdseks jõudnud punkti, kus genoomika andmeid võiks hakata käsitlema rutiinse tervishoiuteenuse kulu-efektiivse komponendina. Viimastel aastatel on maailmas alustatud mitmeid erinevaid personaalmeditsiini projekte. Nende hulka kuulub ka Eesti perso- naalmeditsiini pilootprojekt, millega on plaanis alustada tervishoiusüsteemi tasemel katsetusi 2015. a sügisel. Eesti jaoks loob unikaalse eelise juba praegu olemasolev Eesti Geenivaramu andmekogu 50 000 geenidoonori andmete ning 2300 täisgenoomiga ning teiseks Eesti tervishoiuandmete kõrge digitaliseerituse ja tsentraliseerituse aste. Käesolev raport võtab kokku Eesti personaalmeditsiini pilootprojekti rakendamiseks vajaliku infoarhitektuuri ja andmehalduse het- keolukorra ning täiendavate vajaduste eelanalüüsi tulemused. Hetkeolukorra kirjeldus annab ülevaate olemasolevatest IT infrastruktuuri komponentidest. Märkimisväärne osa Eesti rahva tervise- andmetest on reaalaja andmebaasidest kättesaadav ja iga isiku andmed eri andmekogudes ühendatavad tänu isikukoodidele ja X-tee andmevahetuskihile. Eestis on tänaseks kogutud koeproovid 5% rahvastiku kohta, 2400 neist saavad peagi ülegenoomselt sekve- neeritud. Mitmed teadusgrupid on juba tegelenud andmete kogumise, eraldamise ja kvaliteedi uurimisega, samuti uute otsusetoe algoritmide väljatöötamisega. Sellegipoolest tuleb nimetatud tegevusi käsitleda pigem ad hoc lahendustena, kuna need ei moodusta veel terviklikku tsüklit teadus- ravi-jälgimine-teadus ahelas. Automaatset otsusetuge, mis on personaalmeditsiini oluline osa, ei ole Eesti praktikas tänaseni kasu- tatud, isegi mitte ilma geneetika komponendita. Ka maailmas ei ole valmis rakendataval kujul olemas kõikehõlmavaid automaatse otsusetoe rakendusi ega geneetika baasil tehtavate kõikvõimalike riskiskooride ja ennustusalgoritmide andmebaasi. Sellise algorit- mide andmebaasi ja otsusetoe rakenduste arendamine oleks Eestile unikaalne eelis ja rahvusvahelise koostöö võimalus. Käesolevas raportis kirjeldatakse mõningaid olulisemaid komponente ja probleeme personaalmeditsiini infoarhitektuuri ja andme- halduse kontekstis: eri andmekogudest andmete ühendamine nii teadus- ja rakendusuuringute kui otsusetoe tarbeks, informeeritud nõusolekute haldamine, turvalisus ja privaatsus. Pilootprojektis tuleb leida leida õige tasakaal vähese ja liiase privaatsuse tagamise mehhanismide vahel. Ühelt poolt võib mistahes genoomi info leke tekitada suurt vastuseisu kogu projektile. Teiselt poolt või- vad aga privaatsuse liigse kaitsega seotud takistused drastiliselt pidurdada teadustegevust, mis on pilootprojekti ja tuleviku arengu võtmekomponent. Uuringud on vajalikud nii otsusetoe algoritmide väljatöötamiseks kui rahvusvaheliste ravijuhiste ja algoritmide valideerimiseks Eesti andmetel enne juurutamist. Oma töös jagame personaalmeditsiini tervikprotsessi olemuslikult viieks alamtegevuseks: kliiniline tegevus ja vahetu suhtlemine patsiendiga, isikustatud suurandmete haldus, otsusetoe rakendused, andmete pseudonümiseerimine ja teadus- ning arendustege- vus. Toome välja nende tegevuste jaoks funktsionaalsed nõuded koos võimalike lahendusalternatiividega. Samuti kirjeldame nelja konkreetset kasutuslugu mis katavad neid alamprotsesse. Information Architecture of Estonian Personalised Medicine Pilot Project v Pakume välja neljasammulise strateegia vajaliku infoarhitektuuri loomiseks, kus süsteemi üldist võimekust laiendatakse iga sam- muga. Igal etapil on võimalik läbida kogu personaalmeditsiini protsessi tsükkel. Personaalmeditsiini printsiipide rakendamist alus- tatakse Eesti Geenivaramu doonorite peal ja seejärel laiendatakse lähenemist samm-sammult kogu Eesti elanikkonnale. Rahvusvahelised eksperdid nõustuvad, et just nüüd on õige aeg alustada personaalmeditsiini põhimõtete riiklikul

    OSCE High Commissioner on National Minorities His Excellency Mr Toomas Hendrik Ilves Minister for Foreign Affairs of the Republic of Estonia Rävala 9 TALLINN EE 0100 Republic of Estonia The Hague Reference no.: 21 May 1997 359/97/L Dear Mr Minister, With great interest I read your statement in the Permanent Council of the OSCE on 10 April 1997 in which you commented on our conversation in Tallinn on 8 April 1997. I was glad to note your positive assessment of the efforts I have made since 1993 to be of assistance to Estonia in solving its inter-ethnic problems. I have also studied carefully the papers prepared by your Ministry and sent to the members of the Permanent Council regarding the issues raised during my visit to Tallinn on 8/9 April 1997 and regarding the recommendations I have made to the Government of Estonia during the period from April 1993 to October 1996. Please allow me to send you a detailed reaction which I will also send to the members of the Permanent Council two weeks after you have received this letter. First of all, I should like to make some general remarks about the situation of the over 200,000 persons in Estonia who have neither the Estonian nor any other citizenship. As I have remarked before, I have found no evidence that persons belonging to national minorities in Estonia are systematically persecuted, or that there are persistent violations of their human rights. The assurance I received in July 1993 from the then Prime Minister, Mr Laar, that Estonia does not intend to start a policy of expulsion from Estonia of Russian speakers has been repeated by subsequent Governments and I feel confident that this will continue to be the case in the future.

  • Reforms in the Hospital Healthcare System in Macedonia, Estonia and Hungary
    Reforms in the Hospital Healthcare System in Macedonia, Estonia and Hungary An overview of the implemented reforms, the reactions from stakeholders and evaluation of policies Introduction The aim of this study is to explore healthcare reforms of the public health system in Estonia, Hungary and Macedonia in terms of changes in the level of corporatization, autonomization and decentralization of the health care sector – commonly denominated as New Public Management (NPM), within the period of most recent and intensive reforms for each respective country. The study at hand consists of three individual country reports which reflect and assess the reforms which were implemented within their respective national contexts. Each of the reports, firstly provides an overview of the reforms implemented, while also assessing how these reforms fit within the NPM paradigm. Subsequently, each country report explores the effects of the reforms on health care employees and whether the changes had triggered some kind of collective responses by labor unions and the general public. Each country report concludes by highlighting the potential impact of employees and the public’s reaction in shaping the course of healthcare sector reforms and in the quality of health services in general. Finally, this study concludes with a comparative overview of the general trends in healthcare reforms in all three countries as representative of post-socialist transitioning states. Methodology Reforms in health care sectors were traced by sector-specific government programs and changes in the related legislation. Reaction of employees and the public were mapped through daily news and other media sources, surveys and opinion polls, as well as written declarations and petitions of labor unions and other related employee associations and patients’ representatives.

  • Local Self-Government Reforms in Europe: Legal Aspects of Considering the Communities' Social Identity
    Local self-government reforms in Europe: legal aspects of considering the communities' social identity Professor Tetyana SEMIGINA1 Professor Olena MAIDANNYK2 Professor Yuriy ONISCHYK3 Associate professor Yaroslav ZHURAVEL4 Abstract The implementation of local self-government reform is closely linked to the social identity, a concept that includes common territory of residence, history of origin and development, social interaction, moral standards, values, traditions, interests, habits and needs. In order to study the realm of different European countries in implementing of the decentralization policy and the current state of regulation of the local-self government issues with respect to the social identity the comparative-law, formal and legal, and system- structural methods were used. The cross-national comparative study reveals that in Austria, Spain, France, Poland, the formation of local communities’ associations was preceded with regard to the economic criterion and the permission of the executive branch, while the opinion of local communities’ members is only advisory. In Estonia, the legislation regulates the procedure on the formation of unions of townships or cities, as well as a list of issues to be discussed with local communities’ members. However, the decisive move is still left to the government. In Ukraine, it is statutory that a decision to form a united territorial community could be adopted only after positive discussions with members of the relevant local communities. Keywords. social identity, local community, local self-government, local self- government bodies, local government reform. JEL Classification: K23, K30 1. Introduction Society is viewed as a social environment of human existence; it determines the formation of local communities with their own subculture, history and development that reflects their identity.

Thomas Charles L. Taylor 2 May 2017 Blacksburg, Virginia Keywords: Estonia, post-Soviet, post-socialist, neoliberalism, nationalism, nationalist economy, soft nativism Copyright © 2017 by Thomas M. Denson IV De oeconomia ex natione: An Examination of the Role of Nationalism in Estonia’s Transition from Socialism to Capitalism Thomas Marvin Denson IV Abstract This thesis explores the role played by nationalism in Estonia’s transition to capitalism in the post-Soviet era and the way it continues to impact the Estonian economy. I hypothesize that nationalism was the key factor in this transition and that nationalism has placed a disproportionate economic burden on the resident ethnic Russians. First, I examine the history of Estonian nationalism. I examine the Estonian nationalist narrative from its beginning during the Livonian Crusade, the founding of Estonian nationalist thought in the late 1800s with a German model of nationalism, the conditions of the Soviet occupation, and the role of song festivals in Estonian nationalism. Second, I give a brief overview of the economic systems of Soviet and post-Soviet Estonia. Finally, I examine the impact of nationalism on the Estonian economy. To do this, I discuss the nature of nationalist economy, the presence of an ethno-national divide between the Estonians and Russians, and the impact of nationalist policies in citizenship, education, property rights, and geographical location.

  • The Russian Minority Issue in Estonia: Host State Policies and the Attitudes of the Population
    Polish Journal of Politica l Science Anna Tiido University of Warsaw The Russian minority issue in Estonia: host state policies and the attitudes of the population Abstract The article analyses the recent developments of the relationship between Russian minority in Estonia and its host state. It gives a theoretical background on the minority issue in the triangle of “kin -state/ minority/ host- state”. In Estonia, the principle of Restitution governed the emergence of the Estonian policies. By the end of the 1990s the elites realized that the course towards the integration of the non-Estonian minority should be taken. The mood in the society can be traced from the mostly exclusive citizenship and language policies towards more inclusive course on integration. The author states that after the events of 2014, the attitudes towards the Russian minority were mixed, with some signs of radicalization, but overall there were attempts to include the minority more in the life of the country. Keywords: Russian minority, minorities, Estonia, Russia Vol. 1, Issue 4, 2015 45 Polish Journal of Politica l Science In this article I will analyze the complex relationship between the Russian minority of Estonia and its host state - Estonia. This analysis will take into account the interconnection in the triangle of „kin -state – minority - host-state“, but concentrate on the host state policies and the attitudes of both minority and majority. It is clear that the state of Estonia does not exist in a vacuum, and its policies towards minorities are being largely influenced by the third factor, that of the „kin -st ate“ of Russia.

One of the biggest of these is the constantly increasing number of people suffering from non-communicable diseases. Average life expectancy is growing and modern science is now capable of offering new and efficient treatments. This, in turn, creates the preconditions for a person with one or more chronic diseases to have a greater chance of living longer life with higher quality than decades ago. This is, of course provided that the health system is able to adapt to the new challenges. The Estonian Health Insurance Fund is the biggest purchaser of health care services in Estonia.
