HOS Data Feedback
Individual member level data will not be provided to plans after baseline data collection.
However, organizations will receive the following from CMS:
1. HOS Baseline Report - This report will be made available to all plans participating
in the previous year's baseline cohort. This quality improvement tool, which
presents an aggregate overview of the baseline health status of each MAO's
Medicare enrollees, was developed and extensively tested to ensure that MAOs
would find the data useful and actionable. Each MAO’s QIO will also receive
electronic copies of the baseline reports and is available to collaborate with MAOs
on interpreting the data, identifying opportunities to improve care, assisting with
planning effective, measurable interventions, and evaluating and monitoring the
results of your interventions. Using data from the HOS to plan and conduct a
quality improvement project may fulfill one of the QI program requirements. All
report distribution occurs electronically through HPMS. MAOs are also alerted of
all HOS report and data availability through HPMS.
2. HOS Performance Measurement Report and Data - After the administration of
each follow up cohort, a cohort specific performance measurement report is
produced. Survey responses from baseline and follow up are merged to create a
performance measurement data set. The HOS performance measurement results
are computed using a rigorous case mix/risk adjustment model. The resulting
aggregation of these scores across beneficiaries within a plan yields the HOS plan
level performance measurement results. The performance measurement reports
and corresponding data results are designed to support MAO quality improvement
activities.
3. HOS-M Summary Reports - After each yearly administration of the Medicare
HOS-M, a plan specific report is produced and is available for each organization
participating in the survey. The HOS-M report focuses on PACE plans serving
frail and elderly beneficiaries, and provides a summary of demographic
information, physical and mental health status, and selected health status
measures. The corresponding beneficiary level data for a report are also made
available to participating PACE plans.
All distribution of HOS-M reports occurs electronically to participating PACE
organizations through HPMS. Plans are also alerted of report and data
availability through HPMS.
4. Survey Vendor Reports - The vendors administering the survey may provide you
with reports on the progress of mail and telephone survey administration. Each
report may consist of data on the number of surveys issued during the first and
second survey mailings, the number of surveys returned completed or partially
completed, the number of sampled members for whom a survey could not be
obtained (e.g., due to death, disenrollment, language barrier), and mail and
telephone response rate calculations.
MAOs should not ask their survey vendor for additional analyses or member specific
data. They are prohibited from providing this type of information. Requests for
interpretation of the data or more detailed analyses of the data should be directed to each
MAO’s State QIO.
