Depression among caregivers of cancer patients: Updated systematic review and meta-analysis.

BACKGROUND

It is imperative to provide care for patients with terminal illnesses such as cancer, though it demands time, financial resources and other unmet needs. Subsequently, caregivers might be exposed to psychological stress and other mental health problems. Previous meta-analysis finding shows caregivers of cancer patient suffer from depression. During the past 4 years, there has been a considerable increase in the number of newly studies, and we therefore intended to update this finding and provide current global prevalence of depression among caregivers of Cancer patients.

METHODS

We searched PubMed, SCOPUS, CINAHIL, Embase, and PsychINFO to identify peer-reviewed studies which reported the prevalence of depression among caregivers of cancer patients using pre-defined eligibility criteria. Studies were pooled to estimate the global prevalence of depression using a random-effect meta-analysis model. Heterogeneity was assessed using Cochran's Q and I statistics. Funnel plot asymmetry and Egger's regression tests were used to check for publication bias.

RESULT

Our search identified 4375 studies, of which 35 studies with 11,396 participants were included in the meta-analysis. In the current review, the pooled prevalence of depression among caregivers of Cancer patients was 42.08% (95% CI: 34.71-49.45). The pooled prevalence of depression was higher in the studies that used cross-sectional data (42%, 95% CI: 31-52) than longitudinal data (34%, 95% CI: 18-50). We also observed a higher rate of depression among female caregivers when compared to their male counterparts (57.6%) (95% CI: 29.5-81.5).

CONCLUSION

Globally, around two in five cancer patient caregivers screened positive for depression, which needs due attention. Routine screening of depressive symptoms and providing psychosocial support for caregivers is crucial.
