Healthcare Project (the coding)

Using SQL, I was able to determine which medical specialties are doing the greatest number of procedures on average.  When determining the top 5 procedures.  I omitted the procedures that only had one patient.  I filtered to only show specialties that had a count of 50 or more using the HAVING count feature.  Additionally, I used the same feature to filter on any specialty that has more than 2.5 average procedures.  This gave me a clean list of 10 specialties.


In order to determine if race played a factor in, I used the JOIN function of SQL to add the demographics to the table containing the treatment and health results.  Using the code below, I received the following results.  There does not appear to be any significant gaps between races.


Next, I wanted to determine if lab procedures correlated to days in hospital.  Did those who got more lab procedures stay in the hospital longer?  I used the CASE WHEN function to create a column to group our patients into having “few”, “average”, or “many” procedures.  Once that was done, I used the code below to determine if there was a correlation.  According to my findings, it appears there is a correlation between procedures and average time in the hospital.


Although when many think of data we think numbers.   SQL also has a function that will merge strings together in order to tell us a story.  In this case I used the CONCAT function to provide a written summary of the top 20 patients.
