Complete the worksheet in the database provided for this module's assignment, and submit the database as attachment. See the detailed instruction below. Assignment - Week 3.docx Assignment - Week 3 Database.accdb Instructions on the worksheet: Review the database provided for this week’s assignment. Please generate the following data reports using SQL. All reports should be generated inside the provided database as queries.

Name your queries with numbers 1 to 5 to match with the questions below. Grading will be based on correct SQL statement and the data sheet generated from each query. A list of all patients from outside of the State of Arizona, with their first name, last name, and state. A detailed report on patient visits that occurred before the year of 2009, with patient first name, patient last name, visit date, provider first name, and provider last name. Using nested queries to generate a report on healthcare providers who provided care to Jane Doe, with their first name and last name.

Using aggregate operators to generate a report on the total number of patient visits before the year of 2009. Using GROUP BY clause to generate a report on patients’ average account balance by ethnicity.

The purpose of this assignment is to generate specific data reports from a provided healthcare database using SQL queries. The database, titled 'Assignment - Week 3 Database.accdb', contains multiple related tables including patients, providers, visits, and accounts. The goal is to demonstrate proficiency in SQL by retrieving accurate, relevant data to fulfill five distinct reporting requirements, each representing a different aspect of healthcare data analysis.

Firstly, students are instructed to list all patients who reside outside the state of Arizona, including their first name, last name, and state. This requires a straightforward SELECT statement with a WHERE clause filtering out patients whose state is 'Arizona'. This report helps identify the patient population outside Arizona for demographic and administrative purposes.

Secondly, students are to generate a detailed report of all patient visits that occurred prior to 2009. This report should contain patient first and last names, visit dates, and the first and last names of healthcare providers involved. This involves JOIN operations between patients, visits, and providers tables, filtered by visit date with a condition specifying visits before January 1, 2009. This report offers insights into historical patient-provider interactions and visit patterns.

Third, the task involves using nested queries to identify healthcare providers who provided care to a specific patient, Jane Doe. The inner query should identify visits associated with Jane Doe, and the outer query should extract provider names who attended her. This demonstrates understanding of nested SELECT statements and subqueries in SQL.

Fourth, students should utilize aggregate functions like COUNT to determine the total number of patient visits that took place before 2009. This calculation involves filtering visit records by date and then aggregating the count, providing a summary of early healthcare activity volume.

Finally, the assignment asks for a report using the GROUP BY clause to compute the average account balance for patients grouped by ethnicity. This involves joining relevant account and patient tables, grouping data by ethnicity, and applying the AVG function to calculate mean balances. It offers a demographic financial analysis perspective.

Analysis and Implementation of SQL Data Reports for Healthcare Database

Effective management of healthcare data is crucial for operational efficiency, patient care, and strategic planning. The assignment focuses on employing SQL queries within a healthcare database to extract meaningful insights by generating specific reports. These reports involve filtering, joining, nested queries, aggregation, and grouping functions, each serving a distinct purpose in understanding patient demographics, visit history, provider relations, and financial metrics.

First, identifying patients from outside Arizona involves a simple SELECT statement with a WHERE clause filtering by the 'state' attribute. This task exemplifies basic data retrieval and filtering, essential skills in managing large datasets. The query ensures only patients with states other than 'Arizona' are included, assisting regional demographic analysis. A sample SQL code could be:

SELECT FirstName, LastName, State

FROM Patients


WHERE State  'Arizona';

Secondly, producing a report on visits before 2009 requires joining multiple tables—patients, visits, and providers—to gather comprehensive visit information. The query filters visits with a date earlier than January 1, 2009, highlighting historical healthcare activities. An example SQL query may look like:

SELECT p.FirstName AS PatientFirstName, p.LastName AS PatientLastName,

v.VisitDate, pr.FirstName AS ProviderFirstName, pr.LastName AS ProviderLastName


FROM Visits v


JOIN Patients p ON v.PatientID = p.PatientID


JOIN Providers pr ON v.ProviderID = pr.ProviderID


WHERE v.VisitDate

Next, identifying providers who treated Jane Doe utilizes nested queries. The inner query finds all visits associated with Jane Doe, and the outer query retrieves provider names from those visits. This demonstrates adeptness in subqueries, with a sample SQL outlined below:

SELECT DISTINCT pr.FirstName, pr.LastName

FROM Providers pr


WHERE pr.ProviderID IN (


SELECT v.ProviderID


FROM Visits v


JOIN Patients p ON v.PatientID = p.PatientID


WHERE p.FirstName = 'Jane' AND p.LastName = 'Doe'


);

Fourth, calculating the total number of visits before 2009 employs aggregate functions like COUNT, filtered by date criteria. This provides a summarized view of early healthcare activity volume and can be achieved via:

SELECT COUNT(*) AS TotalVisitsBefore2009

FROM Visits


WHERE VisitDate

Finally, grouping patients by ethnicity to compute average account balances involves joining patients and accounts, then applying GROUP BY and AVG functions. Such analysis reveals financial status across demographic groups. An example query might be:

SELECT p.Ethnicity, AVG(a.AccountBalance) AS AverageBalance

FROM Patients p


JOIN Accounts a ON p.PatientID = a.PatientID


GROUP BY p.Ethnicity;

These queries collectively demonstrate a comprehensive approach to extracting vital healthcare insights from a relational database. Accurate SQL syntax, correct table relationships, and proper filtering are essential for generating reliable reports. Mastery of these techniques supports data-driven decision-making, improves resource allocation, and enhances patient care strategies within healthcare organizations.
