Fifty-one diabetic patients with osteomyelitis of the foot were studied to determine potential prognostic factors and the role of antimicrobial therapy. Most of the patients were elderly, with diminished pulses, a sensory neuropathy, and a polymicrobial infection. Twenty-seven patients had a good outcome, defined as clinical resolution at the time of the last follow-up examination, without the need for amputation. ⋯ Fifteen patients had a below-knee amputation, and nine had a toe amputation. The absence of necrosis and/or gangrene, the presence of swelling, and the use of antimicrobial therapy active against the isolated pathogens for at least four weeks intravenously, or combined intravenously and orally for 10 weeks, predicted a good outcome. Diabetic foot osteomyelitis, in the absence of extensive necrosis or gangrene, usually responds to antimicrobial therapy without the need for an ablative surgical procedure.

In order to determine prognostic factors in noncardiac medical patients treated by mechanical ventilation in a Veterans Administration hospital, 78 patient records were reviewed. Disease severity was scored by the Acute Physiology and Chronic Health Evaluation (APACHE) II system. Physicians' prior impressions of prognostic factors were compared with the actual results of this study. ⋯ At the San Francisco Veterans Administration Medical Center, a low serum albumin level may aid in the decision whether to begin mechanical ventilation, and a high fractional inspired oxygen concentration at 24 hours may aid in the decision regarding further aggressive care. These findings need to be validated in other patients before being applied. Conversely, certain older patients, and those undergoing emergency intubation or intubation for a prolonged time, may have as good a prognosis as patients without these factors.
