While most categories had minor updates, one major change was abandonment of the term \u201chealthcare-associated pneumonia\u201d (HCAP). The guidelines also recommended against use of procalcitonin for the decision to initiate antibiotics; recommended against use of corticosteroids in all cases but pneumonia with septic shock; and recommended obtaining blood and sputum cultures in patients with pneumonia at risk for methicillin-resistant Staphylococcus aureus (MRSA) or Pseudomonas aeruginosa. This review will cover studies published since the 2019 guidelines that help answer unaddressed questions and\/or add clarity to areas of uncertainty.<\/jats:p>","DOI":"10.56305\/001c.91180","type":"journal-article","created":{"date-parts":[[2024,1,3]],"date-time":"2024-01-03T07:26:44Z","timestamp":1704266804000},"source":"Crossref","is-referenced-by-count":0,"title":["Community-Acquired Pneumonia for the Hospitalist: Updates and Controversies"],"prefix":"10.56305","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4943-1197","authenticated-orcid":false,"given":"Joanna M","family":"Bonsall","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03czfpz43","id-type":"ROR","asserted-by":"publisher"}],"name":"Emory University","department":["Medicine"]},{"id":[{"id":"https:\/\/ror.org\/009hj8759","id-type":"ROR","asserted-by":"publisher"}],"name":"Grady Memorial Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"35509","published-online":{"date-parts":[[2024,1,1]]},"reference":[{"issue":"9","key":"ref1","doi-asserted-by":"publisher","DOI":"10.1128\/jcm.00505-23","article-title":"Diagnostic utility of oropharyngeal swabs as an alternative to lower respiratory tract samples for PCR-based syndromic testing in patients with community-acquired pneumonia","volume":"61","author":"Sondre Serigstad","year":"2023","journal-title":"Journal of Clinical Microbiology","ISSN":"https:\/\/id.crossref.org\/issn\/0095-1137","issn-type":"print"},{"issue":"1","key":"ref2","doi-asserted-by":"publisher","first-page":"e21716","DOI":"10.7759\/cureus.21716","article-title":"Evaluation of the Potential Impact of a Multiplex Rapid Diagnostic Panel in Critically Ill Patients With Hospital-Acquired Pneumonia","volume":"14","author":"Bradley J Erich","year":"2022","journal-title":"Cureus","ISSN":"https:\/\/id.crossref.org\/issn\/2168-8184","issn-type":"print"},{"issue":"8","key":"ref3","doi-asserted-by":"publisher","first-page":"e048187","DOI":"10.1136\/bmjopen-2020-048187","article-title":"Combined use of a broad-panel respiratory multiplex PCR and procalcitonin to reduce duration of antibiotics exposure in patients with severe community-acquired pneumonia (MULTI-CAP): a multicentre, parallel-group, open-label, individual randomised trial conducted in French intensive care units","volume":"11","author":"Guillaume Voiriot","year":"2021","journal-title":"BMJ Open","ISSN":"https:\/\/id.crossref.org\/issn\/2044-6055","issn-type":"print"},{"issue":"3","key":"ref4","doi-asserted-by":"publisher","first-page":"106905","DOI":"10.1016\/j.ijantimicag.2023.106905","article-title":"Respiratory fluoroquinolone monotherapy vs. \u03b2-lactam plus macrolide combination therapy for hospitalized adults with community-acquired pneumonia: A systematic review and meta-analysis of randomized controlled trials","volume":"62","author":"Sang-Ho Choi","year":"2023","journal-title":"International Journal of Antimicrobial Agents","ISSN":"https:\/\/id.crossref.org\/issn\/0924-8579","issn-type":"print"},{"key":"ref5","article-title":"U.S. Food and Drug Administration","journal-title":"Fluoroquinolone Antimicrobial Drugs Information"},{"key":"ref6","article-title":"U.S. Food and Drug Administration","journal-title":"Azithromycin Information"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajic.2023.09.007","article-title":"Impact of doxycycline on Clostridioides difficile infection in patients hospitalized with community-acquired pneumonia","author":"Ashley L.
