Monitoring Drug Poisoning Mortality Across States Using Control Charts: A Comparative Analysis

This study examines the impact of drug abuse on mortality rates in two US states: Minnesota, and Vermont. Control charts were utilized to analyze trends in drug-related deaths over time and assess the effectiveness of various policies and changes implemented to reduce drug abuse. The control chart for Minnesota showed in control data an increasing trend in drug poisoning mortality. On the other hand, the control chart for Vermont showed in-control data with cyclic behavior. The results conducted from the control charts suggest that Minnesota has a high rate of drug abuse and drug poisoning mortality that is increasing, while Vermont's drug poisoning mortality fluctuated due to different government policies implemented to prevent drug abuse.
