Learn Visualizing Adverse Event Rates | Clinical Data Analysis and Visualization

Monitoring and analyzing adverse drug events is a critical aspect of pharmacy practice. Adverse events—unintended and harmful outcomes from medication use—can impact patient safety and treatment outcomes. By tracking these events and visualizing their frequency, you can quickly identify which medications are associated with higher risks. Visualization helps you communicate findings clearly to healthcare teams, supporting informed decisions and proactive risk management.

import pandas as pd

# Create a DataFrame with drugs and reported adverse event counts
data = {
    "Drug": ["Amlodipine", "Metformin", "Warfarin", "Atorvastatin"],
    "Adverse_Events": [15, 22, 8, 12]
}
df = pd.DataFrame(data)
print(df)

To understand the distribution of adverse events among different drugs, you can use a pie chart. This type of chart makes it easy to see the proportion of total events attributed to each medication, allowing you to focus on drugs with higher reported issues.

# Customizing the pie chart with percentages for clarity
plt.figure(figsize=(6, 6))
plt.pie(
    df["Adverse_Events"],
    labels=df["Drug"],
    autopct="%1.1f%%",
    startangle=90,
    shadow=True
)
plt.title("Proportion of Adverse Events by Drug")
plt.show()
