The 23 patients (28.8%) who died included 16 (69.6%) with gram-negative infections and 7 (30.4%) with gram-positive infections. There was no statistically significant association of bacterial BSI-related 30-day mortality with Gram stain (\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              =.32). Of 18 patients (22.5%) who were neutropenic, only one (5.6%) died. Sixty-two (77.5%) patients were non-neutropenic, of whom 22 (35.50%) died. We found a statistically significant association between the presence of neutropenia and bacterial BSI-related 30-day mortality (\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              =.016), with mortality being lower among neutropenic patients.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>Gram-negative bacteria are more prevalent in bacterial BSI than gram-positive bacteria. No statistically significant association of Gram stain result with mortality was found. However, the 30-day mortality rate was lower among neutropenic patients than among non-neutropenic patients. We recommend further investigation with a larger sample size in multiple regions to further unravel the association of neutropenia with bacterial bloodstream infection-related 30-day mortality.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>LIMITATIONS:<\/jats:title>\n            <jats:p>Lack of regional data and sample size.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONFLICT OF INTEREST:<\/jats:title>\n            <jats:p>None.<\/jats:p>\n          <\/jats:sec>","DOI":"10.5144\/0256-4947.2023.172","type":"journal-article","created":{"date-parts":[[2023,6,4]],"date-time":"2023-06-04T08:05:06Z","timestamp":1685865906000},"page":"172-178","source":"Crossref","is-referenced-by-count":6,"title":["Prevalence of bacterial bloodstream infections and association between neutropenia and 30-day mortality among oncology inpatients at a university hospital in Saudi Arabia"],"prefix":"10.5144","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5425-9531","authenticated-orcid":true,"given":"Khalifa","family":"Binkhamis","sequence":"first","affiliation":[{"name":"From the Department of Pathology, College of Medicine, King Saud University, Riyadh, Saudi Arabia"},{"name":"From the King Saud University Medical City, King Saud University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim","family":"Aldakhil","sequence":"additional","affiliation":[{"name":"From the College of Medicine, King Saud University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulrahman","family":"Alhawas","sequence":"additional","affiliation":[{"name":"From the College of Medicine, King Saud University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alwaleed","family":"Alsaleh","sequence":"additional","affiliation":[{"name":"From the College of Medicine, King Saud University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amjad","family":"Albaroudi","sequence":"additional","affiliation":[{"name":"From the College of Medicine, King Saud University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bader","family":"Almuhanna","sequence":"additional","affiliation":[{"name":"From the College of Medicine, King Saud University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohaned","family":"Makkawi","sequence":"additional","affiliation":[{"name":"From the College of Medicine, King Saud University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Musa","family":"Alzahrani","sequence":"additional","affiliation":[{"name":"From the King Saud University Medical City, King Saud University, Riyadh, Saudi Arabia"},{"name":"From the Department of Medicine, College of Medicine, King Saud University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3134","reference":[{"key":"e_1_3_2_2_2","first-page":"331","article-title":"Febrile neutropenia.
