However, one should be careful when using CMS-HCC without removing diagnoses from index hospitalization particularly in studies evaluating inpatient processes of care.
However, caution should be exercised in studies evaluating inpatient processes of care and where data on pre-index admission diagnoses are unavailable.
However, it should be used cautiously in studies focused on evaluating inpatient processes of care when complications due to process of care cannot be identified and excluded based on available data.
However, these data also make it possible to exclude diagnoses codes related to complications due to inpatient processes of care by only including diagnoses from inpatient and outpatient claims identified before the index hospitalization date (i.e. exclude index hospitalization claim).
In this case, our results indicate that the CMS-HCC is more favorable than the other two methods because it captures more comprehensive diagnosis information than the Charlson and Elixhauser methods and complications due to inpatient processes of care are not an issue.
The implementation of the inpatient care process is equal for both versions of the model.
As psychoeducation on the indications was part of the inpatient treatment process, we could ensure that all patients received all relevant medical information till the end of the inpatient treatment.
Additionally every module consists of 2 blocks whereby the first one represents the patient's treatment outside the hospital (outpatient care) and the second one refers to the stationary treatment process (inpatient care).
We excluded admissions under these specialty codes because the focus of our study was on patients admitted to general adult psychiatry inpatient beds, where processes of care, diagnostic profiles, and, possibly, risk factors for self harm, differ from those admitted to these specialties.
The indoor light environment of hospital wards may affect functions and symptoms that are central to the process of inpatient recovery, including sleep, anxiety, well-being, and mood.
