Performance measures for alcohol and other drugs services: a commentary.

Alcohol and other drugs treatment includes a wide range of service and personal characteristics, along with expected and unexpected barriers to treatment. To capture the benefits and the gaps of a designed treatment, one needs to consider process-of-care and outcome measurements. Process-of-care measures are mainly developments of the rationale proposed by The Washington Circle and capture all variants in the process-of-care as proportions. Outcome measures are strongly related to different concepts of recovery and described as simple yes/no answers type to wide levels of response, such as in Likert-type scales. According to the studies collected here, more realistic periods of data-collection for process-of-care measures and a more reliable format to capture outcome particularities should be designed.
