Data are presented as mean±sd, unless otherwise stated. In the 2006 National Health and Wellness Survey (NHWS), the hospitalisation question was: “What is the total number of days you were hospitalised for your own medical condition in the past 6 months?” In the 2008 and 2010 NHWS, the question was changed to: “How many times have you been hospitalised for your own medical condition in the past 6 months?” NWC: not well-controlled; ALWC: at least well-controlled; SF-12: short-form 12; PCS: physical component summary score; MCS: mental component summary score. ^#: during previous 6 months; ^¶: includes any form of contact, not just clinic visits.
