Although this virus mutation resulted in milder symptoms, those on the vulnerable side of the population are still in danger of developing severe symptoms. Thus, this systematic review focused on identifying the clinical outcomes of older age patients (&gt;65) that are hospitalized with the SARS-CoV-2 Omicron variant. The research was conducted using four electronic databases (PubMed, Scopus, Web of Science, and ProQuest Central), with a search query in December 2022 that comprised the duration of the COVID-19 pandemic. The inclusion criteria comprised (1) a population of patients older than 65 years, (2) a history of hospitalization for SARS-CoV-2 infection, and (3) infection with Omicron B.1.1.529 variant. The initial search generated 295 articles, out of which six were included in the systematic review, and a total of 7398 patients. The main findings were that when looking at the elderly population, the mortality and hospitalization rates remained high. This is because older people are more vulnerable and have more comorbidities that interfere with the virus\u2019s progress. However, there is inconsistency in mortality rates, since the data reported by the included studies had different selection criteria based on the severity of the COVID-19 infection. Although no statistically significant differences were found between the unvaccinated and vaccinated groups, patients who got booster doses of vaccination had a lower likelihood of developing severe symptoms, serving as a protective factor for this population.<\/jats:p>","DOI":"10.3390\/ijerph20032150","type":"journal-article","created":{"date-parts":[[2023,1,25]],"date-time":"2023-01-25T04:54:41Z","timestamp":1674622481000},"page":"2150","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Outcomes of Elderly Patients Hospitalized with the SARS-CoV-2 Omicron B.1.1.529 Variant: A Systematic Review"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0776-0809","authenticated-orcid":false,"given":"Roxana Manuela","family":"Fericean","sequence":"first","affiliation":[{"name":"Department XIII, Discipline of Infectious Diseases, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"},{"name":"Doctoral School, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2083-0581","authenticated-orcid":false,"given":"Cristian","family":"Oancea","sequence":"additional","affiliation":[{"name":"Center for Research and Innovation in Precision Medicine of Respiratory Diseases, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7933-7591","authenticated-orcid":false,"given":"Akash Reddy","family":"Reddyreddy","sequence":"additional","affiliation":[{"name":"School of General Medicine, Bhaskar Medical College, Amdapur Road 156-162, Hyderabad 500075, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ovidiu","family":"Rosca","sequence":"additional","affiliation":[{"name":"Department XIII, Discipline of Infectious Diseases, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"Bratosin","sequence":"additional","affiliation":[{"name":"Department XIII, Discipline of Infectious Diseases, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"},{"name":"Doctoral School, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vlad","family":"Bloanca","sequence":"additional","affiliation":[{"name":"Department of Plastic Surgery, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3730-6527","authenticated-orcid":false,"given":"Cosmin","family":"Citu","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satish","family":"Alambaram","sequence":"additional","affiliation":[{"name":"School of General Medicine, Bhaskar Medical College, Amdapur Road 156-162, Hyderabad 500075, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neeharika Gayatri","family":"Vasamsetti","sequence":"additional","affiliation":[{"name":"Faculty of General Medicine, Kaloji Narayana Rao University of Health Sciences, Nizampura, Warangal 506007, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catalin","family":"Dumitru","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,25]]},"reference":[{"key":"ref_1","unstructured":"(2022, December 10).
