Abstract

Objectives

We assessed the impact of a recently reported nutritional quality improvement program (QIP) on healthcare resource utilization and costs for older, community-living adults in Bogotá, Colombia.

Methods

The study included 618 community-dwelling, older adults (> 60 years) who were at risk or malnourished and receiving outpatient clinical care. The intervention was a QIP that emphasized nutritional screening, dietary education, lifestyle counseling, 60-day consumption of oral nutritional supplements, and 90-day follow-up. For economic modeling, we performed 90-day budget impact and cost-effectiveness analyses from a Colombian third-party payer perspective. The base-case analysis quantified mean healthcare resource use in the QIP study population. Analysis was based on mean input values (deterministic) and distributions of input parameters (probabilistic). As the deterministic analysis provided a simple point estimate, the cost-effectiveness analysis focused on the probabilistic results informed by 1000 iterations of a Monte-Carlo simulation.

Results

Results showed that the total use of healthcare resources over 90 days was significantly reduced by > 40% (hospitalizations were reduced by approximately 80%, emergency department visits by > 60%, and outpatient clinical visits by nearly 40%; P that is, the per-dollar return on investment was $1.82.

Conclusions

For older adults living in the community in Colombia, the use of our nutritional QIP improved health outcomes while lowering costs of healthcare and was thus cost-effective.
