Implementing Patient and Family Involvement Interventions for Promoting Patient Safety: A Systematic Review and...

The aims of the study were to evaluate and to quantify the effects of patient and family involvement (PFI) interventions on patient safety by synthesizing the available global data.

Four databases were searched to identify relevant studies that have assessed the impact of PFI on patient safety up to March 2019. Reference lists of potential selected articles were also used to identify additional relevant studies. Effect sizes (ESs) were calculated using random and fixed effects models. Statistical heterogeneity was measured using the I2 test.

Twenty-two studies met the review criteria. The meta-analysis showed that PFI were beneficial in significantly reducing adverse events (ES = -0.240, P < 0.001), decreasing the length of hospital stay (ES = -0.122, P < 0.001), increasing patient safety experiences (ES = 0.630, P = 0.007), and improving patient satisfaction (ES = 0.268, P = 0.004). However, the PFI interventions did not significantly enhance the perception of patient safety (ES = 0.205, P = 0.09) or the quality of life (ES = 0.057, P = 0.61). Moreover, moderate-to-high heterogeneity was found for all impacts except adverse events (I2 = 0%) and length of hospital stay (I2 = 35%). A funnel plot indicated a low degree of publication bias for the adverse event outcome.

The synthesized evidence in this review demonstrates the benefits of PFI for promoting patient safety. However, further studies should extend the research scope to fill the existing gaps for both the type of PFI interventions and the patient safety outcomes.
