PaTH Clinical Data Research Network (CDRN) Study of Healthy Lifestyles and Health Care

The primary objective is to create the PaTH Clinical Data Research Network (CDRN) Study of
Healthy Lifestyles, Body Weight and Health Care, which will allow the conduct of
patient-centered observational studies on weight across the multiple institutions of the PaTH
network. Creating the PaTH Clinical Data Research Network (CDRN) Study of Healthy Lifestyles,
Body Weight and Health Care will involve:

1. Recruiting patients with longitudinal weight data in the EHR to participate in the PaTH
Clinical Data Research Network (CDRN) Study of Healthy Lifestyles, Body Weight and
Health Care

2. Administering surveys to the PaTH Clinical Data Research Network (CDRN) Study of Healthy
Lifestyles, Body Weight and Health Care approximately every 6 months to collect patient
reported outcomes (PROs)

3. Collecting individual patient health record data into the PaTH Clinical Data Research
Network (CDRN) Study of Healthy Lifestyles, Body Weight and Health Care database

4. Identifying potential participants for future research studies.

5. Tracking whether the patient participant has biospecimens in a PaTH site biorepository
and prepare for possible sharing of biospecimens in future studies.

The secondary objectives are to use the PaTH Clinical Data Research Network (CDRN) Study of
Healthy Lifestyles, Body Weight and Health Care to answer patient-centered research questions
including:

(1) How do survey response rates, sample demographics and survey responses differ by
recruitment technique? (2) What are patients' weight management strategies? How much are
health care providers contributing to their weight management approaches? Do these
relationships vary by weight status, region, age, sex, or race; (3) What are patients'
reasons for seeking bariatric surgery and expectations in terms of weight change?; (4) Among
patients seeking bariatric surgery, what proportion with high risk for sleep apnea by survey
responses have been evaluated for or diagnosed with this health problem? (5) How does
physical activity vary with patients co-morbidity status?
