Assessment of the Impact of Headache on the Employee Population of Libbs Pharmaceutical Ltd

Migraine has a major impact on quality of life and work capacity . In Brazil, although there are many studies on the prevalence of primary headaches, studies on the impact of this condition on work activities are still scarce. Recently, a cross-sectional study evaluated a large Brazilian cohort, providing important data on the impact of headache on quality of life, work, and use of health resources . However, this study focuses on the general population, including both workers and non-workers. There are still few studies that evaluate the impact of headache on work activities, relating the occurrence and intensity of headache and its impact on productivity to different job positions and hierarchical levels of workers. Thus, given the high prevalence of migraine, its cost in terms of medical care, absenteeism, and impairment of social, family, and especially work activities, a more detailed study of this pathology in a population with high productive potential, such as employees of a national pharmaceutical industry, is urgently needed. Although the clinical manifestations of migraine are well known, the impact of this condition on daily activities, especially in the workplace, is still widely underestimated. In this context, seeking to understand how migraine interferes not only with physical well-being, but also with the emotional, social, and professional dimensions of its employees' lives, Libbs promoted a healthcare program to assess health conditions related to migraine. The assistance program used the Dr. Cefaleia para Médicos (Dr. Headache for Doctors) app with the following questionnaires: ID Migraine, in its validated Brazilian Portuguese version, the Headache Impact Test (HIT-6), also validated in Brazilian Portuguese, and the Brazilian migraine/headache impact questionnaire Work Productivity and Activity Impairment (WPAI). As previously mentioned, the WPAI is a tool that assesses the impact of health conditions, such as migraine, on work productivity and daily activities. The questionnaire included four main parameters: 1. Lost work time (absenteeism): Measures the time the individual was unable to work due to migraine. 2. Work impairment (presenteeism): Assesses the reduction in productivity while the individual is present at work but unable to perform their duties normally due to headache. 3. Overall productivity loss: Combines the effects of absenteeism and presenteeism. 4. Impairment of activities outside of work: Measures the impact of migraine on daily activities that are not related to work. The objective of this research project is to perform statistical analysis of data already collected, without the need for additional primary data collection. Therefore, it will be conducted at the Libbs Farmacêutica LTDA office or remotely, from home. To ensure the efficient and secure execution of the research, the team will have a private and reserved workspace, a stable and high-speed internet connection to facilitate communication between the team and remote access to the necessary database or storage system. Communication within the team will be carried out through platforms such as \[Zoom, Microsoft Teams, Google Meet\] for weekly meetings and discussions on the progress of the research. The team will have computers with appropriate configurations and programs, which will ensure the necessary performance for data processing and analysis. Data protection will be a priority throughout the process. All data transferred to the Libbs team will be anonymized, and unauthorized access will be prevented. To ensure data integrity, periodic backups will be performed on secure servers, and the entire analysis process will comply with the General Personal Data Protection Law, with an emphasis on anonymization and security of personal data. For this study, sociodemographic data (age, gender, education, position, sector, branch), presence of headache (yes or no), diagnosis, types of treatment, and scores from validated questionnaires, such as workLost, workCompromised, productivityLost, activityCompromised, and impact, collected during the assistance program carried out by Libbs with its employees, will be analyzed. The collection of primary data did not involve the collection of directly identifiable personal information, so there will be no data such as name, document number, or other contact information that could identify participants, other than the email address, which was optional. For data whose email or other information allows for the indirect identification of individuals, a data anonymization process will be adopted to ensure that the information processed cannot be associated with specific individuals. The anonymization technique adopted will be the removal or alteration of identifiable data through the following measures: * Replacement of direct identifiers: if the database generated by the Dr. Cefaleia application contains any direct identifiers, these variables will be removed or replaced by random codes. These codes will be generated automatically and will have no relation to the original data that would allow the individual to be re-identified. * Data grouping: Where possible, information will be grouped so that the individuality of each participant is not revealed. For example, variables related to age groups or job categories, department, or branch may be converted into ranges to avoid direct association with a specific individual. * Variable generalization: Some variables that could be used to indirectly identify a person (such as job title, sector, branch, or details of very specific contexts) will be generalized, using, for example, broad categories to preserve anonymity. These measures will ensure that the data used in the study cannot be associated with specific individuals, either directly or indirectly, in accordance with the principles of the General Personal Data Protection Law and the ethical standards applicable to research involving human subjects. Anonymization will be performed by the researcher in charge before any analysis or sharing of data with Libbs, so that any information that allows re-identification will be permanently removed or modified, ensuring that participants remain anonymous and protected throughout the research process.
