Cluster 1 (N=173) had no ICD codes for nervous system (NS) diseases and mental and behavioral disorders. Clusters 2 (N=564) and 3 (N=326) are quite similar except for gender distribution. Cluster 1 was 3.5 times more frequent among non-host cities than HER host cities. Dental treatment was mostly performed on males diagnosed with mental and behavioral disorders and diseases of the NS who were over the age of 25 years and were seen by general dentists. The clusters were distributed unevenly between EHR host and non-host cities.
Conclusion:
Non-host performed more frequently treatment for patients with no mental and behavioral disorders and diseases of the NS than EHR host cities.
