Patients admitted with VOEs are often initially resuscitated with normal saline (NS) to improve concurrent hypovolemia, despite preclinical evidence that NS may promote erythrocyte sickling. The comparative effectiveness of alternative volume-expanding fluids (eg, lactated Ringer [LR]) for resuscitation during VOEs is unclear.<\/p>\n\n\n\n<p><strong>Objective<\/strong>&nbsp;&nbsp;To compare the effectiveness of LR to NS fluid resuscitation in patients with SCD and VOEs.<\/p>\n\n\n\n<p><strong>Design, Setting, and Participants<\/strong>&nbsp;&nbsp;This multicenter cohort study and target trial emulation included inpatient adults with SCD VOEs who received either LR or NS on hospital day 1. The Premier PINC AI database (2016-2022), a multicenter clinical database including approximately 25% of US hospitalizations was used. The analysis took place between October 6, 2023, and June 20, 2024.<\/p>\n\n\n\n<p><strong>Exposure<\/strong>&nbsp;&nbsp;Receipt of LR (intervention) or NS (control) on hospital day 1.<\/p>\n\n\n\n<p><strong>Main Outcome and Measures<\/strong>&nbsp;&nbsp;The primary outcome was hospital-free days (HFDs) by day 30. Targeted maximum likelihood estimation was used to calculate marginal effect estimates. Heterogeneity of treatment effect was explored in subgroups.<\/p>\n\n\n\n<p><strong>Results<\/strong>\u00a0\u00a0A total of 55\u202f574 patient encounters where LR (n\u2009=\u20093495) or NS (n\u2009=\u200952\u202f079) was administered on hospital day 1 were included; the median (IQR) age was 30 (25-37) years. Patients who received LR had more HFDs compared with those who received NS (marginal mean difference, 0.4; 95% CI, 0.1-0.6 days). Patients who received LR also had shorter hospital lengths of stay (marginal mean difference, \u22120.4; 95% CI, \u22120.7 to \u22120.1 days) and lower risk of 30-day readmission (marginal risk difference, \u22125.8%; 95% CI, \u22129.8% to \u22121.8%). Differences in HFDs between LR and NS were heterogenous based on fluid volume received: among patients who received less than 2 L, there was no difference in LR vs NS; among those who received 2 or more L, LR was superior to NS.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/intemed\/0\/ioi240057f1_1725042501.03021.png?Expires=1733409745&amp;Signature=zq04hoj9l-mJOQQaDvRrbgvE-j5C7FlqnPkRjJvmpEye91RN3UAkObnS0WjOnBYc4ioIemBf6hugaK01En8Q3KrNDDLxLG00CRKcFeMGzBHyK~zZ3hMBq7eB55PDZbahayMgM6tSqETG4Ae~nyNh5S6VSV3DNbGYt~Ld-u5SyR8pKX3nPYGgDzHNELLbX~if4pu2v4X8WgGmfdRTZU6P-Sp-ECgxwF65iApEuZiVu4Bs2pyu3B7x6FLX8wMBKh0~4OX~zUxhFgXIOfQf6jc1k6ncIuXoOO1TB2AnHltjgLwV5NZG~NijCUNa~q6nb~6Hl~dgbHhfrNwJ1O1nHLs3GA__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/intemed\/0\/ioi240057f2_1725042501.09797.png?Expires=1733409745&amp;Signature=sgo22XKW-hzAXw8KtObsGQSL33mAsBFuno3MXlrhyOjDc13TFE-uwvMdA0qUk8TimzN~9M8R7UIU9BJHs~1yhI6AECRUbbs4QmDBVPgcQvMQt5zdCaqUqJGw1YBLRkbpdF5qOGPFARYjF0WQ81IHzTPuYfZWUDtbyWWBluJIZDL32BvpVE5zg8zAbalgfXiUPfaRYqYX2AC2B3DNPplp38-eRYRg8CXTqQa8nnc11xvQz7Is41X4dS3vAODU3~BiXpP2F5PdkgMgE-V1pDve-f-ImRvSjhbp75drQ-z6CwE~4gkXGwNkTBcGXn6sohE36mcRA4F~pfJklgNFWPUHuA__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/intemed\/0\/ioi240057t1_1725042501.06689.png?Expires=1733409745&amp;Signature=rKdCurpybXoBWegUOnF3lp4fooLjbCMLKECZCySoUdAap4~8uQV6Er0fyv7C3TeLTznPtH9rB-lqzQCEIGQPCm19P3kYorKlGrRmnFENvoQ04TY~0EFZBMeD7lHzW85TdgBod-Z88A6iwNqNSRYWVDn6TAuBG5D-ZAs67Jfc0Sbbgxh3mDdFZ4Pg8qEP04BPj6Nk6Fy4lO5swGftTNFwposwBUsIyU-TsU4WInHPqFC4akDj1o7o0LLzoW9d5OHAxe3leK3vzLSFjTumby6Qfd8y2FPR79eMAcqLFr0H274yasbJ0Srz1htYWp-Vqa4m3TzTeVhHeNNDCz0Dou0hVw__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/intemed\/0\/ioi240057t2_1725042501.12297.png?Expires=1733409745&amp;Signature=fr24RgQvUGR0SI2mgYDJOs~oEaJH~0-FpkPO2Y7PocyD7aDhGi43SkyWtB4kV6qJWx9XaHACUuToaw4TBl9t3Q4vi5ZirTyPzA0aXyEz5ESZbc-OFFixXfjwongJES9F~3U8FUbFvqgMSbWmodUdKhn1dU5mxpqfs1NqB5E~O~fZVoJ1HoJZNtdXDof8qCC~07zt27p2srBP4j8gHwMjeJWGC7IS5VCp5gW4f-7nPMBEkRahbRlWx0Hmgpj-Qp47fRliNthIq7Hkv2y6yzD8oR8Uf2OGPkif~NttQdP9uBa02sXZuDpiFNcxqL47eLuWL7VyrfVHg-iqr5GUcj2JGw__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<p><strong>Conclusion and Relevance<\/strong>&nbsp;&nbsp;This cohort study found that, compared with NS, LR had a small but significant improvement in HFDs and secondary outcomes including 30-day readmission.
