The effect of a multilevel community health worker-led intervention on health-related quality of life, patient activation, acute care use, and total costs of care: A randomized controlled trial.

Abstract

6500 Background: Low-income and minority populations have less activation in their cancer care, lower health-related quality of life, greater acute care use and total costs of care than affluent and white populations. Community-based interventions are needed to improve patient experiences and quality of cancer care equitably among these populations. We used community-based participatory methods to refine a previously tested intervention for use in urban communities. The intervention, LEAPS, uses community health workers trained to activate patients in discussions with their cancer clinicians regarding advance care planning and symptom-burden and to connect patients with community-based resources to overcome social determinants of health. We conducted a randomized controlled trial of LEAPS in collaboration with an employer-union health plan in Atlantic City, NJ and Chicago, IL. Members of the employer-union health plan with newly diagnosed with hematologic and solid tumor cancers were randomized to the 6-month LEAPS intervention. The objective of the study was to determine whether LEAPS improved quality of life (primary). Secondarily, we evaluated the effect of LEAPS on patient activation, acute care use, and total costs of care. Methods: We used generalized linear regression models to evaluate differences in quality of life and patient activation scores between groups from baseline to 4- and 12-months post-enrollment and regression models offset for length of follow-up to compare emergency department use, hospitalizations, and total costs of care. Results: A total of 160 patients were consented and randomized into the study (80 intervention; 80 control). There were no differences in demographic or clinical factors across groups. The majority were non-White (74%), female (53%), mean age 57 years with breast (31%) or lung cancer (21%) and Stage 3 or 4 (63%) disease. At 4- and 12-months follow-up, the intervention group had greater improvements in quality of life overtime as compared to the control group (difference in difference: 11.5 p < 0.001) and greater change in patient activation overtime (difference in difference: 11.9 (p < 0.001)). At 12-months follow-up there were no differences in emergency department use (0.44 (0.71) versus 0.73 (0.22) p = 0.22) however intervention group participants had fewer hospitalizations (1.55 (0.86) vs. 2.29 (1.31), p = 0.002) and lower median total costs of care ($72,585 vs. $153,980, p = 0.04). Conclusions: Integrating community-based interventions into clinical cancer care delivery for low-income and minority populations can significantly improve patient activation, reduce hospitalizations and total costs of care. These interventions may represent a sustainable resource to facilitate equitable, value-based cancer care. Clinical trial information: NCT03699748.
