Mean Overall Benefit of Analgesia Score (OBAS).24 hours, 48 hours, 72 hours, Day 11Subjects were questioned about their overall benefit of analgesia. Overall benefit of analgesia score (OBAS) assesses current pain at rest, vomiting, itching, sweating, freezing, dizziness, and overall satisfaction with postoperative pain during the previous 24 hours. To calculate the OBAS score, each of the subscale scores (0=minimum; 4=maximum) are summed for a combined OBAS score. Possible scores could range from 0 to 28 with a lower score indicating greater benefit.
Mean Total TSQM-9 Score72 hours through Day 11The Treatment Satisfaction Questionnaire for Medication (TSQM-9) contains 9 items assessing Effectiveness, Convenience, and Global Satisfaction domains. Responses to items are rated on a 5-point or 7-point rating scale. Scores for each domain are computed by adding the TSQM items in each domain and then transforming the values in to a composite score ranging from 0 to 100, with higher scores representing higher satisfaction.

Mean Overall Benefit of Analgesia Score (OBAS).

Subjects were questioned about their overall benefit of analgesia. Overall benefit of analgesia score (OBAS) assesses current pain at rest, vomiting, itching, sweating, freezing, dizziness, and overall satisfaction with postoperative pain during the previous 24 hours. To calculate the OBAS score, each of the subscale scores (0=minimum; 4=maximum) are summed for a combined OBAS score. Possible scores could range from 0 to 28 with a lower score indicating greater benefit.

The Treatment Satisfaction Questionnaire for Medication (TSQM-9) contains 9 items assessing Effectiveness, Convenience, and Global Satisfaction domains. Responses to items are rated on a 5-point or 7-point rating scale. Scores for each domain are computed by adding the TSQM items in each domain and then transforming the values in to a composite score ranging from 0 to 100, with higher scores representing higher satisfaction.

Subjects with an MPADSS score of 9 or 10 were considered ready for discharge.
