The social and medical implications intrinsic to patient zip codes with high opioid fatality may reveal residence in these locations to be a risk factor predicting chronic opioid use after anterior cervical discectomy and fusion (ACDF). The purpose of this study is to determine if residence in Pennsylvania zip codes with high incidence of opioid overdose deaths is a risk factor for chronic postoperative opioid use after ACDF. Preoperative opioid usage did not vary meaningfully between high- and low-risk zip code groups. Patients in high-risk opioid overdose zip codes were significantly more likely to exhibit chronic postoperative opioid use. The Kaplan-Meier curve demonstrated that opioid discontinuation was less probable at any postoperative time for patients residing in high opioid fatality zip codes. Logistic regression found opioid tolerance, smoking, and depression to predict extended opioid use.
