The patient was hospitalized for sepsis due to a gallbladder attack from 25Feb2021 to 03Mar2021. The events gallbladder attack and sepsis required also an ER visit. They did not require a physician office visit. Additional clinical course of the events included the following details. Gallbladder attack turned into infection/sepsis quickly. She previously had an emergency stent placed in her bile duct and now there was a stone in the bile duct and she was unsure if it was related; they will either remove her gallbladder or place a permanent stent. They removed stones and "goop" and placed a stent. Her gallbladder still needed to be operated on, but she was not sick with sepsis anymore. Regarding gallbladder attack the patient reported that it was controlled until further tests and surgery were performed. They couldn't do the surgery due to the infection which had cleared up but she did not want the surgery right now. A stent was placed in the duct until something was done and the stone will be crushed eventually. The patient passed out from the gallbladder attack. She never passed out, she had only ever passed out one other time in her 20's where she stood up too fast. The patient reported that she had to walk slower because she got dizzy and she was trying to adjust to getting home. She walked to the bathroom, used it, and her husband heard a thump while he was using the other bathroom. She was looking at the thermostat and fell in the den and she was surprised she didn't hit anything. Her head hurt from the fall. Sepsis: caller reported that as soon as she went to the ER, she was diagnosed with sepsis. Sepsis resolved the day she was discharged from hospital and when she was dismissed all tests were negative for sepsis. She went home on antibiotics for security for another week after discharge from hospital. Dizzy: it was just trying to get her strength up. She'll just be doing nothing and getting up too fast, it happened to any old person with blood pressure medicines. Dizziness began before she went into the hospital. She was experiencing weakness from being hospitalized and she was trying to gain her strength from being sick. Weakness began during her hospital admission and it was ongoing. On 03Mar2021 the patient underwent lab tests and procedures which included haematocrit: 30.4 %, haemoglobin: 10.4 g/dl (not in normal range yet), CMP: within normal limits (all results were within normal limits, including sodium and potassium), platelet count: 159, RBC count: 3.33 (supposed to be 3.9 or more but could have gotten better by now), WBC: 6.1 x10?/L, blood cultures: the results were not yet listed but sepsis was gone according to discharge blood work. She went to the doctor regularly. Her doctor knew how sensitive that was with her, but that her side effects were probably no more than anyone that experienced that. In some years she did not experience adverse events, specifically she did not with her flu vaccine in 2020. She has had side effects that had made her feel ill for 2-3 days and her niece was a nurse and thought she was making it up. The patient was advised to wait for the 2nd dose, she was unable to get it as scheduled on 08Mar2021. In meantime between receiving her first dose and her appointment for her second dose on 08Mar2021, she was hospitalized. The patient was just coming out of the hospital before 08Mar2021 and she still did not feel well so she cancelled the appointment. The hospital doctors, as well as the doctors approaching more tests with her gallbladder, recommended to not get the second dose as scheduled on 08Mar2021, but they could not recommend how or when to get it.
