ABSTRACT
OBJECTIVE: Limited health literacy (HL) is associated with worse clinical outcomes across medical specialties. The association between limited HL and neurosurgical outcomes remains largely unknown. In this systematic review, the authors synthesized the existing literature on the association between limited patient and/or caregiver HL and neurosurgical outcomes.
METHODS: A systematic search was conducted in PubMed, Embase, CINAHL, and JBI EBP from inception to February 12, 2025, following PRISMA guidelines. Study quality was assessed using the Newcastle-Ottawa Scale. The study design, sample size, population of interest, neurosurgical diagnoses/procedures, HL assessment used, pertinent findings, and related demographic factors were collected.
RESULTS: The search yielded 698 article titles and abstracts, of which 37 underwent full-text review and 6 met inclusion criteria for this systematic review. These 6 studies included 695 neurosurgical patients and/or caregivers and used various methods to assess HL. Neurosurgical outcomes were grouped into the following categories: 1) delivery and timing of neurosurgical care, 2) hospital admission and discharge, and 3) quality of life (QOL) and well-being. Study results were split evenly across these 3 categories, with 2 studies that explored the delivery and timing of neurosurgical care, 2 that examined hospital admission and discharge, and 2 that investigated QOL and well-being. Study designs included 2 prospective observational studies, 3 cross-sectional studies, and 1 qualitative study. Sample sizes ranged from 27 to 300 patients, including pediatric, adult, and mixed (pediatric and adult) populations, as well as caregivers of pediatric and adult patients. All 6 studies were conducted outside the United States. Limited HL was found to be associated with delays in neurosurgical care, increased rates of discharge against medical advice, decreased patient independence, and worse psychological well-being.
CONCLUSIONS: This systematic review highlights the paucity of studies on neurosurgical outcomes among patients and/or caregivers with limited HL, while suggesting that limited HL is associated with worse neurosurgical outcomes. In addition, the lack of studies conducted in the US indicates a geographic gap in the literature. The authors provide a call to action and concrete steps to address the critical need for further research on HL to achieve more equitable neurosurgical care.
