1. Over the course of time, the refinement of the HOS measure has resulted in changes to the definition of a "completed survey." The information in the table provides a presentation of how a completed survey and response rate were calculated at the time of reporting for each of the Baseline and Follow-Up cohorts. Given that the definition of a completed survey has evolved over time, this table should not be utilized for response rate comparisons across the cohorts.

2. For the Baseline cohorts, the reporting units represent the individual MAOs sampled for the survey. However, for the Follow-Up cohorts, the reporting units have been adjusted at the time of the performance measurement reporting to accommodate selected MAO consolidations and service area reductions which occur after the Baseline sampling and by December 31 of the Follow-Up survey measurement year.

3. For the Baseline cohorts, the ineligible beneficiaries met one of the following criteria: deceased; bad address and phone number; bad address and mail-only protocol (Russian only); not enrolled in the MAO; or a language barrier; or were removed from the sample due to age less than 18 years. For the Follow-Up cohorts, the ineligible beneficiaries met one of the following criteria: bad address and phone number; bad address and mail-only protocol (Russian only); not enrolled in the MAO; or a language barrier. ^iv A completed survey is defined as a survey that can be used to calculate physical or mental health summary scores. ^v Please note, ineligible beneficiaries were removed from the denominator in the response rate calculations. In other words, Response Rate = [Completed Surveys / (Sample Size – Ineligible Surveys)] x 100%.
