Kaltenbaugh, D.J., Klem, M.L., Hu, L., Turi, E., Haines, A.J., & Hagerty Lingler, J. (2015). Using web-based interventions to support caregivers of patients with cancer: A systematic review. Oncology Nursing Forum, 42, 156–164. 

STUDY PURPOSE: To survey literature focused on social, psychological, financial, technology, and nursing topics for evidence supporting web-based informational and supportive interventions to improve the health of the caregivers of patients with cancer

TYPE OF STUDY: Systematic review

• FINAL NUMBER STUDIES INCLUDED = 6 
• SAMPLE RANGE ACROSS STUDIES: 13–285 patients
• KEY SAMPLE CHARACTERISTICS: Greater than half were females caring for a family member with cancer; half of caregivers focused on family member with lung cancer; included studies that addressed diverse types of patient cancers (early stage to stage 4); the majority of caregivers attended some college and believed they possessed intermediate computer and Internet experience; unknown caregiver ethnicity in four of six studies 

PHASE OF CARE: Early-stage (breast cancer) to stage 4 (lung cancer)

Three of the five articles used in the systematic review showed that web-based interventions decreased caregiver negative mood. One of the three studies showed that a multifaceted CHESS intervention had a moderate effect size (d = 0.387) to decrease caregiver burden and negative mood (d = 0.436) at six months. Another study using CHESS with a clinical report showed small to moderate effect reducing caregiver negative mood at six months and at one year (d = -0.592). A third study describing an informational intervention showed a large effect size (d = 0.88) on this variable. Two multifaceted interventions and one single-faceted intervention supported lower levels of caregiver stress and perceptions of broad social support. Only two of six studies presented usability score outcomes, and only one study addressed the feasibility of the web-based intervention.

Although only six of 581 initial literacy citations met the systematic review study criteria, those six indicated the successful use of web-based cancer caregiver interventions to meet social and psychological needs. The effect sizes of the six studies compared favorably to traditional interventions focused on caregiver burden, self-efficacy, and quality of life. The limited numbers of articles on web-based interventions that positively affected diverse groups of caregivers’ social, financial, and psychological outcomes support future exploration of the usefulness and feasibility of such interventions for cancer caregiver health.

Studies showing significant effects of web-based cancer caregiver interventions may appear more often in the literature to affect article capturing for this systematic review. The lack of identification of caregiver ethnicity in 80% of the cited studies leaves a gap in understanding how non-Caucasian samples or male caregivers may respond to web-based interventions. Published studies after February 1, 2014 were absent from the review. Only six studies met the criteria for the review.

Increasing the use and success of technology to deliver health-related consumer interventions currently support initial evidence for web-based programs, aligned with traditional cancer care, to improve quality of life of patients with cancer and their caregivers. Additional research identify the dosing of Internet interventions and evidence of the efficacy of various forms of interventions is needed.
