Knowledge Item: CA-Summary of Maximum Patient Outcomes-06
 Psychosocial and Medical Outcomes by Housing Status: Maximum Change Estimates

Positive Outcomes: Maintained or Enhanced Functioning Over Time During Program
[By Housing Status]

Outcomes Difference Due to Housing Status Chi-Square
Quality of Life No c2(2) = 4.631, p = .099
Symptoms No c2(2) = 2.328, p = .312
Psychological Distress No c2(2) = 1.195, p = .550
Service Barriers No c2(2) = 1.211, p = .546
CD4 Count No c2(2) = .094, p = .954
Karnofsky Severity Rating Yes c2(2) = 7.527, p = .023
Viral Load No c2(2) = 3.512, p = .173

The number of patients in each group varies by outcome and may be quite small in some cases. See the final table in Results.

This Knowledge Item is a direct follow-up to a series of Knowledge Items that study the maximum degree of change patients (clients) experience during their treatment episodes. The following table shows the Knowledge Items to which this Knowledge Item is a follow-up.

Dependent Variable Knowledge Item
Quality of Life CA-Quality of Life and Health-42
Self-Perceived Symptom Severity CA-Quality of Life and Health-66
Psychological Distress CA-Psychological Distress-17
Self-Perceived Barriers to Services CA-Barriers and Facilitators-33
CD4 Counts CA-Medical Outcomes-17
Karnofsky Severity Rating CA-Medical Outcomes-21
Viral Load CA-Medical Outcomes-25

The maximum change results presented throughout this Knowledge Base permit an assessment of whether patients change over time on a variety of outcome measures where change is defined as the "best" possible score the patient achieves at any time during the treatment episode as compared to the baseline score. 

This Knowledge Item follows up on the prior results by examining whether groups of patients, disaggregated by their housing status have greater than chance levels of improvement. On most major indicators of outcomes, patients with differing degrees of housing stability had similar levels of positive outcomes, with the degree of positive outcomes significantly above chance levels. Note that this definition of program success means that a patient is either maintained at baseline level or that the scores have improved at some time during the entire course of the treatment episode. The parallel Knowledge Item: Summary of Patient Outcomes-06 uses an alternate definition of patient successful outcomes and suggests approximately the same result.

This chart shows the results for all projects using the item in common to both quality of service questionnaires.

The number of patients in each group varies by outcome and may be quite small in some cases. See the final table in Results.
