Prerequisites

Healthcare professionals encounter a wide variety of data types in their daily work, each with unique characteristics and challenges. Understanding these data types is crucial for accurate analysis, efficient workflows, and better patient outcomes. Healthcare data can be broadly categorized as structured, semi-structured, and unstructured. Structured data includes information that fits neatly into tables or databases, such as electronic health records (EHRs), patient demographics, and lab results. Semi-structured data, like physician notes or discharge summaries, contains some organization but does not conform strictly to a table format. Unstructured data refers to formats like medical images (X-rays, MRIs) and free-text narratives, which are rich in information but require special techniques to analyze. Recognizing these distinctions helps you select the right tools and approaches for extracting insights and making data-driven decisions in medicine.

# Creating a dictionary to represent a patient record
patient_record = {
    "name": "John Doe",
    "age": 54,
    "diagnosis": "Type 2 Diabetes",
    "lab_results": {
        "glucose": 145,
        "cholesterol": 210
    }
}

print(patient_record)

In this example, the patient_record dictionary models a real-world patient record by mapping each field to a specific piece of healthcare data. The keys—such as "name", "age", and "diagnosis"—represent attributes commonly found in electronic health records. The "lab_results" key contains another dictionary, grouping related lab measurements together. This structure allows you to organize patient information in a way that mirrors actual clinical documentation, making it straightforward to retrieve, analyze, and update specific pieces of data. Using dictionaries in Python provides flexibility and clarity when handling complex medical information, supporting effective data analysis and patient care.

# Accessing and updating a patient's lab result
# Retrieve the current glucose level
current_glucose = patient_record["lab_results"]["glucose"]
print("Current glucose level:", current_glucose)

# Update the glucose level after a new test
patient_record["lab_results"]["glucose"] = 130
print("Updated patient record:", patient_record)
