A potentially preventable visit (PPV) is a visit to an emergency room for a condition that could have been treated elsewhere, or averted altogether through better access to preventative care. In 2013, 1.8 million visits to the emergency room in New York State were considered potentially preventable, accounting for 28% of all visits. The purpose of this study was to analyze rates of PPVs for a nine-county region centered upon Monroe County, New York State for the years 2011 through 2016. In order to predict PPV rates (i.e. PPVs per 100 people), I generated a multiple linear regression model using the following demographic variables as predictors, collected at the zip code level: percentage of individuals who are Medicaid beneficiaries, percentage of individuals who are black, percentage of individuals who are Hispanic, and percentage of individuals who are 18 years or older that attained a high school education or higher. This study found that PPV rates in the study area were most highly and positively correlated with rates of Medicaid beneficiaries. The results of the study produced a model with an R squared value of 0.89, and all variables were determined to be statistically significant. The results of this research are valuable because emergency room visits are much more costly than preventative care, meaning that health policy makers, hospital administrators, and health insurance companies all have a vested interest in understanding factors contributing to PPV rates.
