5. Inpatient admission: A patient with type 1 diabetes was admitted with a right heel ulcer that had failed a number of outpatient therapies. Also, because the patient was hypoxic on admission with a history of COPD, he was given supplemental oxygen. He coughed up sputum, and a chest X-ray showed a mild increase in interstitial markings. Consequently, he was treated for acute bronchitis with erythromycin, which provided good results. Gradually, the foot ulcer healed. But the hypoxia persisted, and an increase in his oxygen therapy was helpful. He was to be followed by home health services. Discharge diagnoses: (1) Diabetic foot ulcer, right heel; (2) acute bronchitis; (3) diabetes mellitus; (4) history of COPD.
