Health Indicators and Patient Reported Outcomes. Identification of Significative Items Aimed at Improving Health Care Procceses.

SCIENTIFIC JUSTIFICATION OF THE PROJECT Currently, the value-based (VBHC) approach to health promotes the incorporation of the patient's experience, environment, and characteristics into the clinical data used in decision-making, to improve the efficiency of treatments and improve patient satisfaction and adherence, putting them at the center of the intervention1. Healthcare must be driven by a constant effort to deliver results that truly matter to patients. However, this is hampered by the scarcity of transparent and standardized outcome data. In addition, the lack of clarity regarding the definition of value has led to divergent approaches, the term "value" coexists to convey the humanistic principles that underpin health systems2, and to refer to cost reduction and overall efficiency of the process3. Philosophical value and cost containment are important, however, improving health outcomes is essential for value creation4. One of the benchmarks in the incorporation of patient experience is the International consortium for health outcomes measurement (ICHOM), which has a set of standards ready for use5. The standards have been developed to allow doctors and scientists to document, report and compare the results related to different pathologies in a standardized way. Such international benchmarks improve understanding of the course of diseases and enable the identification of "best practices", producing better informed treatment decisions5. Patients' perceptions of their health and experiences are key to patient-centered care \[6\], these experiences are based on Patient Rated Outcomes Measures (PROM) which are questionnaires that measure patients' views of their health status; and Patient Rated Experiences Measures (PREM) which are questionnaires that measure patients' perception of their experience while receiving care. The questionnaires are based on generic scales of health, quality of life and others specific to pathologies6. The datasets can be used for: research, quality improvement projects, clinical performance evaluation, audit and economic valuation. When carrying out this type of studies, it is necessary to consider the limitations in the PROM and PREM questionnaires6, that sometimes are very focused on clinical and health issues, may have failures in interpretation when extrapolating variables of a social nature to the clinical environment, or refer to specific issues that do not influence or interest the person. Therefore, it is necessary to collect holistic information from different segments of the population according to different factors and individually (location, housing, family environment, occupation, medication status, emerging risks ...), to ensure that heterogeneous data are available from multiple sources7. To analyze the current limitations and detect the key indicators related to the patient's experience and environment, in a preliminary phase of the study, the Institute of Biomechanics of Valencia (IBV) has completed the ICHOM standard guidelines incorporating and expanding the issues related to the patient's environment. This has been done in several pathologies, including Parkinson's Disease (PD), Diabetes Mellitus type I and II (DM I/II), SARS Covid-19 Infection (COVID-19), Chronic obstructive pulmonary disease (COPD) and Stroke (ST). In this context, it should be added that the Institute of Biomechanics of Valencia has worked on a large number of projects, both national and European, having extensive experience in the treatment and analysis of data related to the quality of life of people, clinical data, as well as the conceptualization and development of data collection systems (http://www.activeageing.unito.it/; http://backup-project.eu/; http://www.with-me-project.eu/; https://valenciadata.ibv.org/home). PROJECT OBJECTIVES LONG-TERM GOAL The overall objective of the project is to analyze the incorporation of patient data (personal, work, family and social situation, as well as how they value the health process) to clinical information, and in this way, adapt interventions and treatments to the characteristics and needs of each patient. Thus, it is intended to check if the indicators based on the ICHOM standards provide valuable information to personalize and improve care processes and hospital management. In principle, this will be limited to the population resident in the national territory (Spain). The specific objectives are: * Implement a data collection system based on ICHOM standards. * Study the ICHOM standards to select those indicators that provide information of interest for hospital management. * Study the ICHOM standards to select those indicators that provide information of interest for the improvement of care processes. * To evaluate the usefulness of the indicators generated in specific populations: in this case, Parkinson's Disease (PD), Diabetes Mellitus type I and II (DM I/II), SARS Covid-19 Infection (COVID-19), Chronic obstructive pulmonary disease (COPD) and Stroke (ST) population. * Analyze and validate the proposed questionnaires and procedures (comprehension, ease of self-completion, clarity of the questions, convenience of the questions...) * Identify possible improvements, modifications and expansion of necessary questions, as well as improvements to the methodological process followed OBJECTIVES FOR THE FIRST (CURRENT)PHASE OF THE PROJECT: This document refers mainly to a first phase or preliminary phase of the study, whose main objective is to validate the questionnaires developed by the IBV from the ICHOM guidelines, specifically in relation to Parkinson's Disease (PD), Diabetes Mellitus type I and II (DM I/II), SARS Covid-19 Infection (COVID-19), Chronic obstructive pulmonary disease (COPD) and Stroke (ST) The specific objectives of this first phase are the following: * Unify questionnaires * Assess data quality * Identify key indicators, through a factor analysis * Design a second reduced version of the questionnaires collecting the key indicators and eliminating those items that are exclusive to each other. METHODOLOGY TYPE OF STUDY Cross-sectional study, based on the application of a series of self-administered questionnaires through a web platform. STUDY SAMPLE Sample size: At least 100 healthy subjects (HP) and 150 with the conditions considered (Ideally at least 30 per group: Parkinson's Disease (PD), Diabetes Mellitus type I and II (DM I/II), SARS Covid-19 Infection (COVID-19), Chronic obstructive pulmonary disease (COPD), Stroke (ST)). Specific characteristics described in section 10 (Eligibility) MEASUREMENT TOOLS The data collection will be carried out through the completion by the participants of a series of questionnaires designed by the IBV. These questionnaires collect information related to the characteristics, preferences or habits of life of the patient, as well as the impact of the disease in different areas. The first questionnaire has a general approach, and the second is specific to each of the diseases of the cohorts considered. Questionnaires described in section 9: Outcome Measures As it is a data collection study based on online questionnaires, it will not be necessary for the IBV research staff to use the facilities. MEASUREMENT PROTOCOL Potential participants will initially be contacted by the corresponding key entity or agent (collaborators specified in the corresponding section 3. Sponsor/Collaborators), including the IBV itself through the databases of previous trials. The IBV will contact those users interested in participating, who meet the inclusion criteria, and who give their consent to be contacted. The questionnaires will be answered by the patients themselves through an online platform. In case it is not possible to use this route, due to limitations of the disease, the questionnaires will be carried out by telephone call. These questionnaires will be filled out once by each participant. VARIABLES ANALYZED The variables analyzed correspond to the items collected in each of the questions of the questionnaires. Questionnaires described in section 9: Outcome Measures. STATISTICAL ANALYSIS A statistical analysis will be carried out that will serve to respond to the objectives of the study. The statistical analysis will treat the data provided by the variables related to the ICHOM indicators and how they are related to each other, testing differences according to the characteristics of the patient and clinical indicators. To do this, contrast tests or significance tests will be performed, applying non-parametric tests because the variables to be analyzed are nominal or ordinal, they do not follow a normal distribution. To do this, an alpha error of α\<0.05 will be taken, which means that, if there are differences between groups of patients, the probability that we are wrong is less than 5%. Below are different non-parametric analysis techniques that are planned to be applied, which are based on range tests: * χ² test. This test considered as a non-parametric test that measures the discrepancy between an observed distribution and a theoretical one, indicating to what extent the differences between the two, if any, are due to chance in the contrast of hypotheses. It is used to test the independence of two variables from each other, by presenting the data in contingency tables. * Kruskal Wallis test. It is a statistical test that allows to analyze if there are differences between two or more independent groups and quantitative variables, in this case between ordinal variables, based on rank test. The variable of interest must be orderable, such as the Visual Analog Scale (VAS) for pain. * Cluster analysis. It is a multivariate statistical technique that seeks to group elements (or variables) trying to achieve maximum homogeneity in each group and the greatest difference between groups. It will be used to identify patient profiles or patterns regarding experience in the health process. DATA MANAGEMENT AND PROCESSING A user code will be assigned to each participant, so that the questionnaires can be linked while maintaining the anonymity of the participants for the IBV. This code will be the one provided to identify yourself in the online questionnaire, or the one that will be added to the questionnaire that is completed by telephone, if applicable. All information will be anonymized for processing and analysis, and may be used under the terms and conditions dictated by the current legal framework. Once the project is finished, the data obtained will be stored, always in an anonymized form and under the legal custody of the IBV. The subsequent use and retention period of the data are governed as contemplated in the informed consent documents, with respect to current legislation. The acceptance of the written document of Informed Consent is made through checkboxes at the beginning of the online survey itself. In the case of patients who are surveyed by telephone, the document corresponding to Written Informed Consent will be sent before the interview, and subsequently they will be asked for consent verbally, after ensuring that they have reviewed and understood the conditions of their participation in the study.
