This project focuses on analyzing healthcare data to uncover key insights into patient admissions, medical conditions, treatment outcomes, and hospital performance. By combining Python for data preparation and cleaning with Power BI for interactive dashboards, the project aims to support healthcare administrators in making data-driven operational and clinical decisions.
The Healthcare Data Analysis and Visualization Project involves working with a multi-sheet Excel dataset containing patient details, hospital information, doctor records, and patient visit data. The project workflow starts with merging and cleaning the data using Python libraries such as Pandas and NumPy in a Jupyter Notebook environment. Key data cleaning steps included handling missing values, standardizing text data, mapping admission type codes, calculating patient length of stay, and identifying high billing cases.
After preparing a clean and integrated dataset, exploratory data analysis (EDA) was performed in Python to validate data distributions and detect anomalies. The prepared dataset was then visualized in Power BI, where a series of interactive dashboards were built to deliver actionable insights.
The dashboards created include:
🔍 Overview Dashboard: Patient Admissions Summary: Visualizing patient admission counts, age distribution, gender splits, and admission trends.
🏥 Medical Condition & Outcome Analysis: Analyzing the frequency of medical conditions, treatment outcomes, and recovery rates.
💵 Billing & Insurance Analysis: Tracking billing amounts, insurance coverage patterns, and flagging high-cost cases.
🧑⚕ Doctor & Hospital Performance: Evaluating doctor-wise and hospital-wise patient outcomes, admissions, and billing performance.
📅 Time-Based Analysis: Examining trends over time including admissions, discharges, and length of stay patterns.
This project demonstrates how Python-based data engineering can seamlessly integrate with BI tools like Power BI to deliver healthcare insights that improve operational efficiency and patient care decisions.

This notebook begins with a descriptive exploration of the patient and hospital datasets using summary statistics and visual analysis. It then examines patterns in patient demographics, admission types, and medical conditions to understand what factors may influence hospital stay duration. Finally, relationships between variables such as department, billing, and severity of illness are analyzed further.
The data in the healthcare dataset includes information about patients admitted to hospitals across different medical conditions. It contains 55500 rows and 17 columns, with data spanning several years, starting from 2019. The dataset includes details such as patient ID (Pid), doctor ID (Did), hospital ID (Hid), medical condition, date of admission, insurance provider, billing amount, room number, admission type, discharge date, medication prescribed, test results, patient name, age, gender, blood type, doctor name, and hospital name.
Key variables in the dataset include medical condition (Cancer, Diabetes, Asthma, Hypertension), billing amount (non-negative real numbers), room number (integer), admission type (Elective, Emergency, Urgent), and medication (Lipitor, Aspirin, Paracetamol). The age and blood type variables are numerical, while gender and insurance provider are categorical variables. The test results vary, with categories like Inconclusive, Abnormal, Normal and NaN values.
Data Cleaning & Preparation is the process of identifying and fixing errors, inconsistencies, and missing values in raw data, transforming it into a structured, reliable, and analysis-ready format for further processing.
To perform a complete analysis, we merge all four datasets using their respective key columns (Pid, Hid, Did). This helps consolidate patient_details, hospital_details, doctor_details, and patients_data into a single unified DataFrame for further exploration and visualization.
After merging all datasets, we ensure the Name, Doctor, and Hospital columns are clean and consistently formatted. This helps eliminate redundancy, avoids mismatched values, and improves overall data quality for analysis and visualization.
Identifying Mismatches and Foreign Key Issues Between Pid, Did, and Hid in Merged Data and Master Tables.
Identify and appropriately handle missing values in the dataset to prevent incomplete analysis or errors during visualization.

Ensure columns like dates, amounts, ids & age have correct data types for analysis.
Creating useful new columns like Length of Stay & Billing Category
mapping or encode categorical values for better readability.
Creating charts and graphs to make sense of data patterns, trends, relationships, and anomalies visually.
Univariate Analysis is the simplest form of data analysis where only one variable is analyzed at a time to understand its distribution, central tendency, spread, and underlying patterns.
Bivariate Analysis is the analysis of two variables simultaneously to explore the relationship, association, or correlation between them and understand how one variable affects or relates to the other.
Multivariate Analysis is the analysis of more than two variables simultaneously to understand complex relationships, interactions, and combined effects among multiple variables within a dataset.
Understand data distribution patterns and proportions.
