tear given the time course of vomiting and then hematemesis, however, tears were not found. he did not ever require blood transfusion. in house anticoagulation was with pneumoboots instead of chemical prophylaxis in the setting of this gi bleed. he should continue the pantoprazole 40 mg daily for 4 weeks. . # viral gastroenteritis: the initial cause of his gi illness was probably norovirus, contracted from his granddaughter with similar symptoms. this is supported by the time course of illness and his symptoms. his c. diff and stool cultures were negative. his symptoms resolved and he had good po intake before discharge. . # leukocytosis: likely from gastroenteritis. resolved with conservative management. . # elevated inr: his inr on admission was 1.8 he received vitamin k 5 mg po with improvement in his inr before the . in the setting of decreased albumin, the elevated inr might represent decreased synthetic function of the liver in a cirrhotic patient. he does have a significant drinking history although he claims his outpatient gi doctor monitors liver function every 1-2 years and has always been normal. he underwent a ruq ultrasound which showed no evidence of cirrhosis. . chronic issues: # low back pain: he reported that his pain was at baseline. he was continued on oxycodone 5-10 mg q4 hours prn pain. his ibuprofen was stopped due to upper gi bleed. instead, he was given a prescription for acetaminophen 325-600 mg q6h prn pain. he was told that this would be better to take at least 3 times a day for chronic pain with oxycodone as breakthrough. . # communication: patient, wife # code: confirmed full . transitional issues: - there is a chart history of coronary artery disease and hyperlipidemia, however he was not taking medications as an outpatient for risk modification. the patient denies having a history although prior notes do list it as a problem. have this followed by pcp with lipid checks and consider starting statin and aspirin. asa was not started in-house given concern for gi bleed. -
