Decreasing influenza impact in lodges: 1997-2000 Calgary Regional Health Authority.
Influenza causes high morbidity and hospitalization rates in residents of seniors lodges, I causing increased pressure on emergency departments and hospital beds every winter. This quasi-experimental study assessed the prevention of influenza outbreaks and their consequences in Calgary lodges. A multidisciplinary team worked to improve communication between health professionals, increase resident and staff immunization coverage, obtain weights and creatinines prior to influenza season, and facilitate amantadine prophylaxis during influenza A outbreaks. We had an increase in standing orders for amantadine and up to 56% of residents from one lodge had documented creatinine levels. Amantadine was administered to residents within two days of outbreak notification. Influenza morbidity in lodge outbreaks decreased from a rate of 37% to 9% over the three years and hospitalization rates decreased from 9% to 1%. We recommend that other regions consider a similar approach to decreasing influenza morbidity and hospitalization in lodge residents.
