What is the clinical evidence from this study?

Study design: Observational. Population: Obesity (n=2028). Intervention: Roux-en-Y gastric bypass (RYGB) surgery. Primary outcome: Availability of post-operative weight data at 4 years.

What does this research mean for the field?

Over 74% of patients undergoing Roux-en-Y gastric bypass surgery have post-operative weight data available in the electronic health record at 4 years of follow-up, demonstrating that EHR-derived data can be efficiently obtained to study long-term bariatric outcomes.

Implication

EHR data may support efficient long-term bariatric outcome research; leaves open generalizability and causal robustness.

Study Design

Type

Observational (n=2,028)

Multicenter

Structured PICO

Population

2028 patients who underwent Roux-en-Y gastric bypass (RYGB) surgery between 2004 and 2010 at an integrated health delivery system, median age 46, 81% female, 97% Caucasian.

Intervention

Roux-en-Y gastric bypass (RYGB) surgery and electronic health record (EHR) data extraction

Outcome

Length of post-operative follow-up (availability of post-operative weight data)

A variety of EHR-derived data related to obesity can be efficiently obtained and used to study long-term outcomes following Roux-en-Y gastric bypass.

Limitations

Clinical measurements recorded in the EHR may lack the stringent standardization of research protocols, potentially introducing systematic errors.
ICD-9 codes were used as surrogates for co-morbidities without independent validation of their accuracy.
Medication reconciliation was used, but not all filled prescriptions are necessarily taken by patients.
Missing laboratory data occurred when tests were not ordered or were performed at outside laboratories.
Survey data had lower response rates compared to other clinical data domains.
Clinical measurements in EHR may have systematic errors due to varying procedures and equipment
Medication usage based on reconciliation, not actual patient use
ICD-9 codes used as surrogates for co-morbidities without validation from supporting data
