Standardized Telephonic Case Management in a Hispanic Heart Failure Population: An Effective Intervention
Tomas E. Romero
Background: Heart failure (HF) is as common in Hispanic as it is in non-Hispanic populations. However, there do not appear to be any published reports of HF disease management programs which include Hispanic populations. Objective: To test the effectiveness of a standardized telephonic disease management intervention, Pfizer Inc.'s At Home With Heart Failure(TM), in decreasing acute care resource use and cost in Hispanic patients with HF. Participants and methods: A factorial design was used to analyze data obtained in a randomized controlled clinical trial. Patients with HF were enrolled in the trial when admitted to hospital, randomized to the intervention or usual care control groups, and followed for 6 months. Of the 358 participants, 93 (26%) were Hispanic (35 in the intervention group, 58 in the usual care group). Data were analyzed to determine if comparable decreases in acute care resource use were evident in Hispanic and non-Hispanic intervention group patients. Intervention: Registered nurses telephoned patients after hospital discharge to provide advice, solve problems, encourage adherence, and facilitate access to needed services. Results: Acute care resource use was lowered as effectively in the Hispanic patients as in the non-Hispanic patients, despite significant between-group differences in education, income, and living situations. When a fully crossed (language by group) analysis was conducted, no significant differences were found between the Hispanic and non-Hispanic intervention groups. However, in most categories there was a trend towards lower resource use in the Hispanic intervention group. The cost of inpatient care was more than $US1000 (2000 values) less in the Hispanic than the non-Hispanic intervention group. Conclusion: The results of this study suggest that Hispanic patients with HF are receptive of, and responsive to, a case management intervention provided in a culturally competent manner, despite differences in cultural views on chronic illness and self-care as discussed in the literature.
