Bayesian continuous-time hidden Markov models with covariate selection for intensive longitudinal data with measurement error.
Liang M, Koslovsky MD, Hébert ET, Kendzor DE, Businelle MS, Vannucci M. Liang M, et al. Psychol Methods. 2023 Aug;28(4):880-894. doi: 10.1037/met0000433. Epub 2021 Dec 20. Psychol Methods. 2023. PMID: 34928674 Clinical Trial.
To accommodate potential biases, we develop a Bayesian hidden Markov model to simultaneously identify risk factors for subjects transitioning between discrete latent states as well as risk factors potentially associated with them misreporting their true behaviors. ...

Assessments of Heart Failure and Frailty-Related Health Instability Provide Complementary and Useful Information for Home-Care Planning and Prognosis.
Heckman GA, Hirdes JP, Hébert P, Costa A, Onder G, Declercq A, Nova A, Chen J, McKelvie RS. Heckman GA, et al. Can J Cardiol. 2021 Nov;37(11):1767-1774. doi: 10.1016/j.cjca.2021.07.009. Epub 2021 Jul 22. Can J Cardiol. 2021. PMID: 34303783
METHODS: We undertook a retrospective cohort study of home-care clients, aged 65 years and older, between January 1, 2010, and March 31, 2015 from Alberta, British Columbia, Ontario, and the Yukon, Canada. We used multistate Markov models to derive adjusted odds ratios (OR …

Predicting Future Health Transitions Among Newly Admitted Nursing Home Residents With Heart Failure.
Heckman GA, Hirdes JP, Hébert PC, Morinville A, Amaral ACKB, Costa A, McKelvie RS. Heckman GA, et al. J Am Med Dir Assoc. 2019 Apr;20(4):438-443. doi: 10.1016/j.jamda.2018.10.031. Epub 2018 Dec 17. J Am Med Dir Assoc. 2019. PMID: 30573437
MEASURES: Mortality and hospitalization were plotted over 1 year. Multistate Markov models were used to estimate adjusted odds ratios (ORs) for transitions to different states of health in stability, hospitalization, and death, stratified by heart failure diagnosis and by …

A decision-theoretic approach in the design of an adaptive upper-limb stroke rehabilitation robot.
Huq R, Kan P, Goetschalckx R, Hébert D, Hoey J, Mihailidis A. Huq R, et al. IEEE Int Conf Rehabil Robot. 2011;2011:5975418. doi: 10.1109/ICORR.2011.5975418. IEEE Int Conf Rehabil Robot. 2011. PMID: 22275621
This paper presents an automated system for a rehabilitation robotic device that guides stroke patients through an upper-limb reaching task. The system uses a partially observable Markov decision process (POMDP) as its primary engine for decision-making. ...
