This study is a multi-center study conducted across five sites in the United States to determine the efficacy of combining Osteopathic Manipulative Treatment(OMT)with antibiotics as a treatment regimen for elderly patients with pneumonia. The study is a prospective, randomized, controlled clinical trial, in which 360 subjects will be randomly assigned to three different groups to test the primary hypothesis that the combination of OMT and antibiotics will decrease the length of hospital stay for elderly patients with pneumonia. The first group (OMT Group) will receive a series of eight osteopathic manipulative techniques in combination with conventional antibiotic care. The second group (Light Touch Control Group) will receive a light touch mimic treatment in combination with conventional antibiotic care to control for the doctor-patient interaction. The third group (Conventional Care Only Group) will receive only the conventional antibiotic care normally given to elderly patients with pneumonia. The first two groups will receive two 15-20 minute treatments per day, at least six hours apart, for the duration of their stay in the acute care facility.
