Mimic-code: Overview on MIMIC-III

There is no publicly available frequency chart for psychiatric ICD (-9) diagnoses in MIMIC, as far as I'm aware. You could explore the MIMIC-III demo to see whether you can find the information that you're interested in (https://physionet.org/content/mimiciii-demo/1.4/), but the small patient number might limit your insights. If you list some ICD-9 codes here, someone reading the issue may find the time to take a look.

The demo dataset contains only data for _"all intensive care unit (ICU) stays for 100 patients"_. So it is not useful in my case (i.e. get an overview about the number of psychiatric patients and their ICD-9 Codes: 290-319). For me, it would be very helpful to get an overview of ICD-diagnoses so that I can decide in advance if it makes sense for me to take the registration course.

For example, the signature databank offers such an overview.

As a start, here is a quick query to pull out patients with this range of ICD-9 codes (ordered by number of distinct patients):

SELECT a.icd9_code, b.long_title, count(distinct a.subject_id) as n_patient, 
FROM `physionet-data.mimiciii_clinical.diagnoses_icd` a
LEFT JOIN `physionet-data.mimiciii_clinical.d_icd_diagnoses` b
ON a.icd9_code = b.icd9_code
WHERE a.ICD9_CODE BETWEEN '290%' and '319%'
GROUP BY a.icd9_code, b.long_title
ORDER BY count(distinct a.subject_id) DESC
LIMIT 40;

Thanks, that's a good start and in exactly what I wanted. Of course, it would still be practical, if this overview could be implemented as a feature in the future.
