Brief summary

The services table describes the service that a patient was admitted under. While a patient can be physicially located at a given ICU type (say MICU), they are not necessarily being cared for by the team which staffs the MICU. This can happen due to a number of reasons, including bed shortage. The SERVICES table should be used if interested in identifying the type of service a patient is receiving in the hospital. For example, if interested in identifying surgical patients, the recommended method is searching for patients admitted under a surgical service.

Each service is listed in the table as an abbreviation - this is exactly how the data is stored in the hospital database. For user convenience, we have provided a description of each service type.
