Abstract
Introduction Proton pump inhibitors have been used in conjunction with dexamethasone to treat patients with COVID-19. This is given prophylactically to anticipate possible complications while on steroids, including abdominal pain, gastric ulcers, or gastrointestinal bleeding. Proton pump inhibitors have complications, including Clostridium difficile infection, pneumonia, osteoporosis, and vitamin deficiency. The goal of the following project is to assess if there are any subjective and objective benefits to be treated with this regimen instead of dexamethasone on its own. Another inquiry that will be investigated is if this combination results in more patients being prescribed a proton pump inhibitor on discharge. Materials and methods The following is a retrospective study involving two groups, the first group taking the aforementioned regimen and the second group on dexamethasone only. Objective findings that will be compared include the change in hemoglobin, blood urea nitrogen, and creatinine levels from admission to discharge between the two groups. Subjective findings include complaints of abdominal pain and reported bloody bowel movements. Medication reconciliation on discharge will also be assessed to observe if patients were discharged with a proton pump inhibitor and how long were they taking this medication as an outpatient. Results The difference between hemoglobin, blood urea nitrogen, and creatinine between the two groups was not significant as the p-values were .14, .43. and .10, respectively. Therefore, the null hypothesis was accepted that there was no difference in these objective findings between the two populations. In addition, neither set had complaints of abdominal pain. For the investigated population on a proton pump inhibitor, it was found that 53% of these patients were discharged with this medication. This subset was on this medication for an average of three months, with the maximum duration being seven months for one patient. The data supported the hypothesis that there was no subjective or objective benefit to being on this drug combination, and consequentially, most patients continue to take this medication for months after discharge. Conclusion The data affirms the hypothesis that most patients can tolerate dexamethasone without the need for a proton pump inhibitor. This study was limited to patients without any history of gastritis, peptic ulcer disease, or gastrointestinal bleeding; a separate study would need to be done to investigate the need for prophylaxis for patients with these comorbidities. The concerning finding was that patients are being discharged with a medication that they do not need, some patients are taking proton pump inhibitors for more than half the year. There should be further screening to determine if a patient needs to be on a proton pump inhibitor other than steroids.
