Brief Summary

The research question is, does a multifaceted, multidisciplinary intervention including small groups, chart audits and point of care tools, increase the number of people receiving optimal vitamin D therapy in the long term care (LTC) setting? Secondary outcomes include the number of falls and fractures experienced by the residents in each LTC home and the number of residents receiving appropriate bisphosphonate therapy.

LTC Osteoporosis Toolkit Only

NO INTERVENTION

Homes will receive the LTC osteoporosis toolkit only and will be required to attend an online webinar to outline the toolkit contents.

Educ sessions & LTC Osteoporosis toolkit

ACTIVE COMPARATOR

LTC homes will receive the LTC osteoporosis toolkit, on line webinar. Three educational sessions lead by an osteoporosis expert will also take place, 1 on-site visit and 2 webinars.

Interventions

Educ sessions & LTC Osteoporosis toolkitOTHER

Three points of contact to be made. The first being a 1-hour personal visit at each intervention LTC home from an osteoporosis expert with the homes professional or health advisory committee (PAC or HAC). The second and third contact points will be made through webinars between the osteoporosis expert and the group from the first meeting.
