A blog post “PowerPivot Interest By Industry” noted that healthcare was the top industry. One of the key reasons is that while healthcare systems have a lot of patient transactional data, it’s often left to analyst using Excel to understand the meaning behind all of this information.
“A common question in hospitals is, once a patient discharged, how often are they readmitted to hospital. This type of re-admission analysis is very important because it ultimately allows analysts to determine why patients are coming back to hospital within a set number of days of being discharged.
Below is an example screenshot of obfuscated sample readmission data from a healthcare customer. As you can see, there’re some large disparities between department discharges (in blue) and re-admission rates (in red). For e.g., while the pulmonary department has relatively few discharge cases, they’ve highest re-admission rate near 35%. Meanwhile, internal medicine has largest number of discharges, yet one of the lower readmission rates.”
