Nurse-led interventions linked to reduced depression and improved quality of life after stroke
A meta-analysis of 18 studies (n=1,916) found that nursing interventions delivered across the stroke care continuum were associated with large reductions in post-stroke depression and meaningful gains in health-related quality of life, though effects on anxiety and neurological recovery remained uncertain.
Post-stroke depression and anxiety impede rehabilitation and long-term wellbeing. Researchers synthesized evidence from 18 randomized and comparative studies (1,916 patients total) to evaluate whether nurse-led interventions could improve psychological outcomes and recovery.
For depression, nursing interventions produced a large effect: a standardized mean difference of -1.17 (95% CI -1.65 to -0.70; p < 0.001) across 17 studies with 1,916 participants—substantially larger than typical antidepressant effects in some populations. Health-related quality of life also improved substantially (SMD 1.15, p < 0.001) across 6 studies with 951 patients. Sleep quality showed modest but reliable improvement (SMD -0.27, p = 0.025) in 3 studies with 349 participants. However, anxiety outcomes were uncertain: 5 studies (n=580) showed a non-significant pooled effect (SMD -1.06, p = 0.061), and neurological recovery showed no clear benefit (4 studies, n=419, p = 0.422). A key limitation was very high heterogeneity in depression outcomes (I² = 95%), suggesting substantial variation in intervention types and study quality; Egger's test also flagged possible small-study bias, meaning smaller, potentially positive studies may have been overrepresented.
The depression finding (SMD -1.17) represents a large effect size—roughly equivalent to or exceeding typical pharmacological interventions—but the very high heterogeneity (I² = 95%) masks important variation: some studies used cognitive-behavioral approaches, others integrated peer support or structured self-management, and intervention duration ranged from weeks to months. The quality-of-life improvement (SMD 1.15) was similarly robust and less heterogeneous (I² = 93.5%), suggesting that broader psychosocial support may have more consistent benefit than targeting a single symptom. The sleep finding is interesting but modest: a SMD of -0.27 is clinically small, yet statistically significant, and came from only 3 studies with low heterogeneity (I² = 16%), suggesting the effect is more consistent than the depression results but smaller in magnitude. The lack of effect on anxiety (p = 0.061, bordering non-significance) and neurological recovery (p = 0.422) is notable—this suggests nurse-led interventions may work primarily through psychological pathways (mood, quality of life perception) rather than neuromotor restoration. Trials were generally moderate-quality with some risk-of-bias concerns, so effect sizes may be inflated.
