We conducted a cluster-randomized controlled trial where nursing homes were randomized to either use of a clinical pathway or usual care for management of nursing home acquired pneumonia. The clinical pathway included chest radiographs performed on-site in the nursing home by a mobile x-ray unit, use of hypodermocylysis (subcutaneous infusion) for re-hydration, administration of an oral antimicrobials, and use of pulse oximetry to assess oxygenation. The main outcomes were hospital admission rate and length of stay. Secondary outcomes included health related quality of life, rates of both infectious and non-infectious complications within four weeks of onset of symptoms; mortality rate of residents with pneumonia (death from all causes within 30 days of onset of symptoms. Time to stabilization of vital signs, as well as functional status at four weeks, were assessed.
