Care Trajectories and Chronic Ambulatory Care Sensitive Conditions: Secondary Data analysis and patient-oriented research
Doctor Alain Vanasse's research is based on secondary data analysis of health care administrative data, medical records, populational and geographical data, with an ecological approach. His research interests include epidemiology, pharmacoepidemiology and health geomatics. He is interested in patients with chronic and mental conditions, and Ambulatory Care Sensitive Conditions, in terms of health services utilization, efficacy of treatments and health outcomes. Since 2013, Dr Vanasse performs a series of funded research on care trajectories analysis, a field of research in full emergence. His work aims to better understand the patterns of care use in ambulatory care settings (consultations, diagnoses, preventive care, pharmacological treatments), in Emergency departments (high-frequency users, complex patients), and in hospitals (medical and diagnostic tests, interventions), as well as patient outcomes ("preventable" hospitalizations, early readmissions, and health status - morbidity, disability, mortality). In collaboration with expertise in several disciplines (such as biostatistics, medical informatics, clinical research and health economics), he works on the development and application of predictive models and sequential measurement methods for care trajectories (typologies, clustering, stratification).
Since the beginning of the 2000s, Dr Vanasse is also dedicated to the improvement of health databases for research, in terms of access and quality. In particular, he worked on the implementation of electronic clinical records, social statistics and survey data, spatial data, and hospital clinical data. More recently, he led the development of a population-based cohort for the study of care trajectories, now available to researchers in the “Centre d’accès aux données de recherche de l’Institut de statistique du Québec” (CADRISQ). He is also collaborating on the development of an infrastructure to facilitate the access and exploitation of enriched data and electronic medical records for patient-oriented research and reflective practice.
The research activities of Dr Vanasse are focused on improving clinical and organizational practices, evidence-based decision-making in public health, with a learning healthcare system approach.
