Background: Hospital readmissions are common, costly, and associated with poorer quality of care. Existing models have not performed adequately in assessing hospital readmission risk and do not always account for social variables that may be important predictors of readmission risk, including social support. Results: Models of readmission risk at 30, 90, and 180 days were constructed with social support network size (SSQN) and quality (SSQS) as the primary variables of interest. Although several of the constructed models achieved overall statistical significance, social support measures were not significant in any of the models. As expected, the Charlson Index score, a measure of comorbidity was significantly associated with readmission risk.
