About

The overall goal of this study is to use the National Health and Aging Trends Study (NHATS) data to gain an understanding of how multiple chronic conditions impact the health outcomes of older adults with back pain.

Full description

This study seeks to gain knowledge regarding how multiple chronic conditions affect the health and function of older adults with back pain. The investigators will perform a retrospective cohort study using secondary analysis of the National Health and Aging Trends Study (NHATS) data. NHATS collected longitudinal data on Medicare beneficiaries over 65 for six years, from 2011-2017. This set of data is comprehensive and includes self-reported survey data as well as physical performance data, both of which this study will utilize.

The specific aims include to 1) Estimate the longitudinal associations of the number of chronic conditions, using a standard classification scheme, with long-term physical performance, function, and recurrent falls, 2) Identify specific combinations of chronic conditions that are most strongly associated with long-term physical performance, function, and recurrent falls, 3) Determine the association of the number and type of chronic conditions with rehabilitation service use. The investigator will test a corresponding hypothesis for each aim: 1) Medicare beneficiaries reporting back pain with a greater number of chronic conditions will have worse physical performance, lower functional status, and be more likely to experience recurrent falls over 6 years, 2) Medicare beneficiaries reporting back pain with common and potentially modifiable conditions of anxiety, depression, and arthritis (individually and combined as dyads or a triad) will have worse physical performance, lower functional capacity, and be more likely to experience recurrent falls over 6 years, 3) Medicare beneficiaries with back pain and multiple chronic conditions will report lower use of rehabilitation services in the past one year compared to those with back pain alone or one additional chronic condition.

Trial design

8,344 participants in 1 patient group

Bothersome back pain

Description:

The investigators will include community-dwelling older adults at Round 1 or 6 of the NHATS cohort, and will include those with bothersome back pain in the past month based on self-report questions at the respective baseline time point. The investigators will exclude participants who are non-ambulatory (requires wheelchair or scooter).
