The Long-term Effects of an Intensive Lifestyle Intervention for Type 2 Diabetes on Medicare Outcomes

Type 2 Diabetes Mellitus Clinical Trial

Official title: The Long-term Effects of an Intensive Lifestyle Intervention for Type 2 Diabetes on Medicare Eligibility, Health Care Use, and Health Care Spending

Status Completed

Clinical Trial Summary

This study investigates whether an intensive lifestyle intervention for type 2 diabetes had long-term effects on Medicare enrollment, health care use, and health care spending.

Clinical Trial Description

The Look AHEAD study tested whether participants with type 2 diabetes assigned to an intensive lifestyle intervention (ILI) for weight loss exhibited reductions in cardiovascular morbidity and mortality, relative to a control group receiving usual care and diabetes support and education. During the 12-year intervention period, the ILI led to persistent reductions in weight, waist circumference, and hemoglobin A1c and improvements in physical fitness. In addition, the ILI led to reductions in hospitalizations, hospital days, and prescription drug spending during the intervention period (through 2012). However, the longer-term effects (2012 and later) on health care use and spending remain unknown.

In an ongoing ancillary study, the researchers are investigating the effects of the ILI on economic outcomes, during and after the study. As a part of this study, the study team is linking consenting Look AHEAD participants to Medicare databases. The researchers will investigate the long-term effects of ILI on health care use and health care spending.

By 2012 nearly all Look AHEAD participants were eligible for Medicare due to age (over 65). To the extent that Look AHEAD participants developed severe disabilities, the participants may have gained Medicare eligibility earlier through enrollment in Social Security Disability Insurance (SSDI). Thus, the researchers will also test for differences in the Medicare enrollment channel between ILI and control group participants, specifically whether the groups enrolled through SSDI at different rates. ;
