The first Russian Consensus on the quantitative assessment of the adherence to treatment approved by the XII National Congress of physicians (Moscow, 22-24 November 2017). The Consensus on the quantitative evaluation of the adherence to treatment in clinical practice and working out the most effective strategies of therapy for the patients needing a long-term or permanent treatment has been developed for the first time. In medical practice, where questionnaires are preferable, allowing to investigate the adherence quantitatively and which are applied commonly for patients with different diseases, have the ability of automated input and data processing. Consequently, the Russian questionnaire of the quantitative assessment of the adherence to treatment QAA-25. The identified adherence is used to forecast the effectiveness of specific interventions. For this purpose, the obtained data of the respondent's adherence are compared to the ranges of values corresponding to the appropriate levels of adherence (high, medium, or low). If the value of the identified adherence indicator falls within the values range of the corresponding level, this indicates the forecast variant of the intervention effectiveness, which is the most likely for all values within such a scale. This does not exclude that in some cases the individual characteristics of a particular respondent or other unforeseen external influences may affect the actual effectiveness of interventions due to that they may be more or less effective than it is forecast.
Keywords: adherence to treatment, quantitative assessment, recommendations, Russian consensus
Первый Российский консенсус по количественной оценке приверженности к лечению разработан для пациентов, нуждающихся в длительном или постоянном лечении, и утвержден на XII Национальном конгрессе врачей (Москва, 22-24 ноября 2017 года). В медицинской практике предпочтительны опросники, позволяющие исследовать приверженность количественно, которые могут применяться для пациентов с различными заболеваниями, с возможностью автоматизированного ввода и обработки данных. Этим свойствам отвечает российский опросник количественной оценки приверженности к лечению КОП-25. Выявленная приверженность используется для прогнозирования эффективности конкретных мероприятий. Для этого полученные данные приверженности респондента сравнивают с диапазонами значений, соответствующими уровням приверженности (высокий, средний или низкий). Если значение выявленного показателя приверженности попадает в диапазон значений соответствующего уровня, то это указывает на прогнозируемый вариант эффективности вмешательства, который является наиболее вероятным для всех значений в рамках такой шкалы. Это не исключает, что в некоторых случаях индивидуальные особенности конкретного респондента или другие непредвиденные внешние воздействия могут повлиять на фактическую эффективность вмешательств в связи с тем, что они могут быть более или менее эффективными, чем это прогнозируется.
Ключевые слова: приверженность к лечению, количественная оценка, рекомендации, Российский консенсус

INTRODUCTION
The Consensus on the quantitative assessment of the adherence to treatment in clinical practice and working out the most effective strategies of therapy for the patients needing a long-term or permanent treatment has been developed for the first time. The Consensus creation has been preceded by the elaboration of the approximate practical recommendations for doctors (2016) and the Protocol of quantitative assessment of the adherence to treatment in clinical medicine (2016).
The preparation of the present document and its publishing motivated by the increasing role of adherence to treatment in the therapy of patients with chronic internal diseases and provided for the last ten years advent of accessible, and applicable in medical practice instruments which allow quantitative research of the adherence to treatment.
The essential factors shaping the demand for the quantitative assessment of the adherence to treatment are:
- stated by the Russian Ministry of Healthcare task to create a National patient-oriented system of health protection as a basis for the Strategy of healthcare development in Russia for the period up to 2025;
- implementation of the Unified state informational system in the sphere of healthcare which includes the
creation of the multi-functional automated workstation for doctors, allowing accessing modern highly effective methods and applications;
- formation of the cluster of the innovation-centered medical science development and healthcare for the creation and import of new medical technologies;
- steadily increasing demand of the national healthcare for automated systems supporting medical decisions in cases of a responsible choice, primarily, such necessities as the prescription of an expensive long-term treatment or medicines with a narrow therapeutic range, also, the need of the prescription of medicine with the high risk of dangerous interactions and medication with the «withdrawal syndrome».
The Consensus is based on the following principles:
(I) Justification of the Consensus provision based on adequately completed researches which were detected during the comprehensive analysis of the literature;
(II) The priority of the data of the randomized controlled trials (RCT), multilevel circular trials (CT) in the medical practice and meta-analysis of similar trials taking into account the results of observational and other trials if they are of a proper scientific quality;
(III) Indication of the grades of recommendations (GD) and the levels of scientific evidence (LE) on the mainly discussed issues (Tables 1 and 2), providing the interested
reader with a standardized basis for comparing the state of scientific knowledge in different medical spheres, and drawing doctors' attention to the provisions based on data with high evidentiary, not only on the experts' opinions;

Levels of evidence Criteria
Evidence Level A Data derived from multiple randomized clinical trails
Evidence Level B Data derived from a single randomized trial or nonrandomized studies
Evidence Level C Consensus opinion of experts
(IV) To facilitate the use of Consensus in everyday practice, the focus is mainly on the presentation of the material in the form of tables containing sets of statements and recommendations that doctors could easily and quickly.
The evidence base of the Consensus is based on the publications included in the Cochrane Library, EMBASE, MEDLINE, and ELIBRARY databases. The period of researching equals to at least 25 years. Meta-analysis, systematic reviews, recommendations, and consensuses of the medical societies, data of RCTs and CTs were included in the analyzed base. During the selection of publications as potential sources of evidence, the methodology used in each study was assessed, taking its validity into account.
Key definitions
Adherence to treatment is a comprehensive model of the patient's health behavior which is implemented as the matching rates of such evaluation regarding the recommendations received from the doctor, taking medicines, following the diet and other changes of lifestyle.
Adherence to drug therapy is the ability of a patient to follow medical recommendations regarding medication for an uncertain period.
Adherence to medical support is the ability of a patient to follow medical recommendations regarding
daily medical supervision and health self-monitoring for an uncertain period.
Adherence to lifestyle modification is an ability of a patient to follow medical recommendations regarding the diet and physical activity modification and the limitation or rejection of undesirable habits for an uncertain period.
Integrated adherence to treatment in an average (taking into account the ratio of each controlled parameter in the calculation formula) indicator characterizing a patient's ability to follow medical recommendations regarding drug therapy modification, medical support, and lifestyle modification.
Quantitative assessment of adherence is a way of study in which the adherence is quantified in the nominal scale and expressed as a percentage of the estimated maximum.
The level of adherence is a clustering a common feature based on given quantitative indicators of the adherence and, therefore, allows to include a patient in a group with a similar prognosis of medical interventions and to whom may be applied the treatment management model that is the same for all members of this group and which is the most effective in comparison to other groups.
Adherence sufficiency is the relevance between the identified level of adherence for a particular patient and anticipated effectiveness or safety of a particular medical intervention.

TECHNOLOGICAL MODULE Consolidated statements and toolkit
The adherence to the treatment is usually understood as a degree of the relevance between the patient's behavior and the recommendations received from the doctor, regarding taking drugs, following the diet and other measures of lifestyle changes.
Adherence to the treatment of patients suffering from chronic diseases is one of the most important factors ensuring the quality of therapy and directly influencing the prognosis. The most significant consolidated statements and agreements, which are characterized by the highest classes and evidentiary levels, are presented in Table 3.
One of the main methods of the assessment of the adherence (direct question; counting drugs; measurement of drug concentration or their metabolites in the human liquids; monitoring of visits and interventions, electronic monitoring; using of remote control systems, questionnaires)and the best on the ratio of labour effort to efficiency is questionnaire.
Inmedicalpractice,wherequestionnairesarepreferable, allowing to investigate the adherence quantitatively and which are applied commonly for patients with different diseases, have the ability of automated input and data processing. Consequently, the Russian questionnaire of

Questionnaires for the quantitative assessment of the adherence to treatment can be performed either in an automated or manual mode.
Questionnaire in manual mode
The questionnaire made on paper is filled by the respondents themselves or with the help of an interviewer. A questionnaire is a form that includes 25 questions with answer options. For each question included in the ques-
tionnaire the respondents choose the most appropriate answer in their view from a closed list of answers.
Two variants of the questionnaire are applied: to quantify the adherence to treatment of patients with chronic diseases and to quantify the potential adherence to treatment of patients without diseases and/or those who are unaware of them, or those who are without clinical signs and symptoms (Table 4). The questionnaires differ in the wording of some questions with an equal number of questions and answer options.

For the questions 1, 6, 7, 10, 11, 12 there are following answer options: «absolutely unimportant», «almost unimportant», «rather unimportant than important», «rather important than unimportant», «quite important», «very important».
For the questions 2, 3, 4, 5, 8, 9, 13, 14, 15 there are following answer options: «Very difficult», «quite difficult», «rather difficult than easy», «rather easy than difficult», «almost easy», «absolutely easy».
For the questions 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 there are following answer options: «I won't do it for sure», «I'd rather do», «More likely that I won't do than I will», «More likely that I will do than I won't», «Almost certainly I will», «I will certainly do it».
There is only one possible answer for each question of the questionnaire.
After filling in the questionnaire, the result is processed with calculation formulas in a manual mode or using an automated calculator disconnected from the Internet.
The questionnaire in automated mode
For automated questioning respondents (themselves or with the help of an interviewer) using a personal computer, a laptop, a smartphone, or any other electronic system providing access to the Internet, enters the site with the questionnaire (www.prognoz-med.ru) and activates the application «Adherence to treatment», where they fill in the questionnaire, sequentially entering the information into the working fields and answering the questions.
After filling in the electronic questionnaire, the result is processed automatically and issued as a report with recommendations in PDF format, which
can be saved by the user as an electronic document or printed out.
The questionnaire results processing
The questionnaire results can be processed either in an automated or manual mode. For each question, there are six options of answers which are evaluated in points. The number of points corresponding to each answer option is given in Table 5.

The results are processed in two stages. At the first stage, the technical indicators are calculated: «the importance of drug therapy», «the importance of medical support», «the importance of lifestyle modification» and «willingness for drug therapy», «willingness for medical support», «willingness for lifestyle modification».
Each technical indicator is a simple sum of points received after answering the corresponding questions (Table 6). Thus the minimum possible value for each technical indicator is 5 points, and the maximum possible value is 30 points.

In the second stage, the indicators of the adherence are calculated: «adherence to drug therapy», «adherence to medical support», «adherence to lifestyle modification» and their integral indicator: «adherence to treatment» (Table 7).
Each of the mentioned above indicators is a value calculated for the particular respondent and expressed as a percentage of the theoretically possible value and regarded as 100 %.
For all indicators of the adherence, a level of values in the range up to 50 % is interpreted as «low», from 51 % to 75 % as «medium», more than 75 % as «high». The interpretation of levels of adherence is presented in Table 8.

CLINICAL MODULE Medical strategies and interventions effectiveness
Managing the treatment, regarding the identified levels of adherence for a particular patient, is aimed to achieve the maximum possible result of therapeutic interventions for each level of adherence. The primary medical strategies elaborated in the studies which are of sufficient level of evidence on the criteria of this Consensus, and for which the full or predominant
agreement of the experts have been reached, are presented in Tables 9-11.

um Recommendations on correction of habitual diet, and also on kinds, frequency and amount of the physical activity should be presented in the form of specific brief information; these recommendations should first of all refer to the leading disease IIa, B
Low Recommendations on limitation of undesirable habits are reasonable to present as a limited list of solutions and actions which are the most important in reducing life-threatening risks; full or partial rejection of unwanted habits is unlikely or impossible IIa, B
Recommendations on diet correction and physical activity should be specific and very brief; general recommendations on correction of habitual diet and physical activity are ineffective IIa, B
The identified adherence is used to forecast the effectiveness of specific interventions. For this purpose, the obtained data of the respondent's adherence are compared to the ranges of values corresponding to the appropriate levels of adherence (high, medium, or low). if the value of the identified adherence indicator falls within the values range of the corresponding level, this indicates the forecast variant of the intervention effectiveness which is the most likely for all values within such a range. This does not exclude that in some cases the individual characteristics of a particular respondent or other unforeseen external influences may affect the actual effectiveness of interventions due to that they may be more or less effective than it is forecast.
For each level of adherence, the most probable forecast of the effectiveness of the specific intervention is presented as the following symbols:
«+» - intervention will be implemented completely or invasion is more likely to be performed entirely than implemented partially or not applied;
«+/-» - intervention is more likely to be implemented partially than wholly or invasion is more likely to be implemented partially than not implemented;
«-» - intervention is more likely not to be implemented wholly or partly, or invasion will not be implemented at all.
Based on the quantitative assessment of the adherence the most likely results of interventions are described in Tables 12-14, approximate recommendations are given in Tables 15-17.

Level Recommendations for patients
High In most cases of chronic diseases, taking medicines permanently is required. All drugs can be divided into preventive that do not let the disease worsen or prevent its complications (for example, aspirin doesn't allow blood clots form) and curative, which fight the disease (for example, insulin helps to assimilate sugar when having diabetes). For effective treatment, you need to take both kinds of medicines and you are ready for it. Following the recommendations of the doctors, you usually accurately follow their recommendations on taking drugs. If you have several diseases for which you receive treatment, inform each of the doctors whom you consult, because when having different diseases sometimes similar drugs are applied, and taking them simultaneously can worsen the state of health

In most cases of such diseases you need to have regular laboratory tests, instrumental examinations and visit doctors. However, the patients can take care of their health themselves, and you can do it. If necessary, you can control the level of blood sugar, cholesterol and other things yourself. Talk to your doctor what kinds of laboratory tests you need to do and how often, what indicators should be taken into account, and what changes should be a sign for you to consult the doctor. Coordinate with your doctor an approximate plan and timing of the necessary instrumental examinations. When visiting a doctor, take the results of the laboratory test and instrumental studies, including those which are made by recommendations of other specialists

Medium Chronic severe diseases require medical supervision and support, and you are more or less ready for it. When having such diseases, it is necessary to have regular laboratory tests, instrumental examinations, and visit doctors. However, if you are very busy, you can take care of your health yourself. To do this, talk to your doctor, what laboratory tests and instrumental examinations you should do and how often, and what changes should be a sign to consult the doctor immediately. Talk to the doctor which examinations (for example, blood pressure measurement, blood sugar test and others) you can do yourself - it will prevent you from additional visits to the doctor.

If you visit a doctor due to such a disease, talk to him/her what is essential for you to do to stop your disease from progressing. Highlight the most important things in organizing your daily routine. Find out which physical activities are the most harmful and dangerous for you and try to avoid them. If it is necessary to change your routine diet, first of all, specify what food and beverages you have to avoid, try to remember them and if possible avoid consumption of this food and drinks. If you have overweight, ask your doctor whether you can reduce it and specify what simple ways are the most effective for your disease. It is more likely to be very difficult for you to reject undesirable habits - smoking or excessive consumption of alcohol (if you have them). However, it is possible. In this case, talk to your doctor about which of these habits are the most dangerous for you and why highlight the main problem and try to cope with it. Although you do not believe in the importance of daily routine and diet, you can make little but significant changes in your lifestyle in such a way as to live long and well

METHODOLOGY FOR THE CONSENSUS PREPARATION
1. The experts from all the federal districts of the Russian Federation, including President and Vice-Presidents of RSMSP, plenipotentiary representatives of RSMSP in the federal districts, the leading specialists of the Ministry of Health of Russia and a number of federal districts, teaching staff and scientific employees of the institutions of the applied higher education, medical practitioners, also system analysts, specialists in programming and artificial intelligence were involved in the creation of the «The 1st Russian consensus on the quantitative assessment of the adherence to treatment».
2. The following objective was defined: the optimization of medical interventions basing on the quantitative assessment of the adherence to treatment.
3. Working group and Committee of experts established.
4. A draft Consensus, structured on a modular basis, has been established. The modules are formed based on provisions corresponding to the highest classes and evidentiary levels accepted for the present Consensus. Technological module: tools and technology for the quantitative assessment of the adherence to treatment. Clinical module: the optimization of medical interventions basing on the quantitative assessment of the adherence to treatment.
5. An Internet application «Adherence to treatment» has been created, which includes an online questionnaire for the quantitative evaluation of adherence to treatment with automated data processing and result formation.
6. The Consensus project and the Internet application are posted on the website: www.prognoz-med.ru
7. Method of Consensus validation: external expert assessment; internal expert assessment. In the preliminary versions, the Consensus was reviewed by the independent experts whose task was, first of all, to assess whether the interpretation of the evidence, underlying the document, was understandable. Also, there were given comments by medical specialists and general practitioners regarding the clarity of the Consensus recommendations and the appreciation of their importance as a working tool in daily practice. The preliminary version was also sent to reviewers who do not have medical education to receive comments regarding the prospects for understanding the Consensus recommendations by patients.
8. The questionnaires containing the basic Consensus aspects have been prepared to gather expert opinions.
Level Recommendations for patients
High You realize that in case of severe disease, you will have to change your routine lifestyle and you are ready for it. If you visit a doctor due to such a disease, ask him/her to give you detailed recommendations on how to organize the daily routine. Find out which physical activities are healthy in your condition and which are harmful. If your disease requires special exercises or other activities - ask your doctor to tell you about them, try to write them down, and do them in the future. If you need to change the routine diet, find out in detail what food and beverages should prevail in the diet, and which ones are better to avoid. If you have overweight, you can normalize or reduce it significantly by following the doctor's recommendations. You are also able to substantially limit or completely reject undesirable habits -smoking or excessive consumption of alcohol (if you have them). In general, it is much easier for you than for many others to regulate your lifestyle in such a way as to live long and well
Medium You understand that in case of severe disease, you will have to change the routine lifestyle, and you will have to make a significant effort to do this. If you visit a doctor due to such a disease, ask him/her to give you brief and specific recommendations on how to organize the daily routine. Find out which physical activities are healthy in your condition and which are harmful. If your disease requires special exercises or other activities - choose the most important ones to concentrate on them and do them in future. If it is necessary to change your routine diet, first of all, specify what food and beverages you have to avoid, try to remember them and if possible avoid consumption of this food and drink. If you have overweight, ask your doctor whether you can reduce it and specify which the most effective ways in your case are. It will be difficult for you to reject undesirable habits - smoking or excessive consumption of alcohol (if you have them), but it is quite possible. If you have such habits, ask your doctor which of them is the most dangerous for you and why to highlight the most crucial problem and try to cope with it. Even though you do not believe in the importance of daily routine and diet, you can adjust your lifestyle in such a way as to live long and well
