Figure 1. Mean observed change for Sovereign Health Residential patients (blue bars) relative to the mean expected change for 50 other mental health organizations (yellow bars), October through December 2016.
McLean Hospital determines an organization’s performance based on the Joint Commission’s performance guidelines:
- Undesirable or does not meet performance guidelines = Z score less than -2.576
- Expected performance = Z score between -2.576 and +2.576
- Desirable or excellent performance = Z score greater than +2.576
Based on these guidelines, Sovereign’s Residential Program met or exceeded the Joint Commission’s performance guidelines. For all categories [depression/functioning, relationship/interpersonal competence, psychosis, substance abuse, emotional lability (for example, mood swings) and self-harm] and overall, Sovereign’s average performance at the expected performance level; in most instances, Sovereign’s clinical effectiveness surpassed the national average performance.

McLean Hospital’s report substantiates Sovereign’s high quality of treatment provided to patients with mental health and substance use disorders. Compared to other Joint Commission-accredited organizations, Sovereign admitted much sicker patients over the same three-month period. Notably, Sovereign outperformed the national average of 50 other Joint Commission-accredited organizations for the following categories:
- Emotional lability (e.g., mood swings)
- Substance abuse
- BASIS-24 overall
Sovereign Health’s residential patients reported a decrease of nearly 58 percent in the area of depression and an overall reduction of 52.1 percent, compared to the national average of 37 percent. Sovereign also performed exceptionally well in reducing other self-reported symptoms and functional difficulty at discharge. For example, patients reported a decrease of 70.3 percent in the domain of substance abuse, a 60.8 percent reduction in self-harm and a 57.5 percent decrease in psychosis from admission to discharge.
Figure 3. Average symptom ratings for Sovereign Health’s Partial Hospitalization Program (PHP) patients (N = 40) relative to 50 non-Sovereign Health treatment facility patients (N = 29,638) at admission and discharge.
Sovereign Health’s PHP also met the Joint Commission performance guidelines for October through December 2016, with average clinical effectiveness well above the cut-off for acceptable performance. In addition to meeting the Joint Commission criteria across all domains, Sovereign’s PHP exceeded the performance guidelines for overall change (Z = 3.68) and depression (Z = 3.39). For these categories, Sovereign’s average clinical effectiveness surpassed the national average performance of 50 other Joint Commission-accredited organizations.
Sovereign’s PHP also admitted much sicker patients than other treatment centers did over the same three-month period. Per the report, Sovereign’s PHP patients achieved a 52.1 percent reduction in their overall symptom severity and functional difficulty, relative to the national average of 37 percent.
