The patient denominators used to calculate rates include those patients who were enrolled in VSP at any time during the calendar year. VSP enrollment data is based primarily on employer-provided enrollment data, and may not accurately reflect the actual number of patients enrolled in vSP over the course of the year. In addition, some patient enrollment data is incomplete. In particular, state of residence is not always reported, with 8% of enrollees not having a state of residence on file. For the purposes of this analysis, we distributed patients with missing state in the denominators to a state based on the distribution of patients with known state location. We will continue to investigate possible approaches to improve state location coverage, and mitigate any potential bias of this limitation

NORC I 2016 VSP Summary Data Report for the vision& Eye Health Surveillance System Stratification Factors We report the summary outcomes of each data indicator overall, and by the stratification factors ag group, sex, race/ethnicity, and state. This report includes outcomes estimated for single levels of stratification. The VEHSS data visualization application allows users to estimate prevalence rates specific to multi-variable stratification categories. For example, a user could query outcomes for 85+ year old Hispanic females in Florida. Age Group This report and the public dataset includes the VEHSS-defined major age groups(0-17, 18-39, 40-64, 65 84, 85+). Restricted data used for statistical integration will utilize the expanded WHO age groups(0-1 1-4,5-9,10-14,etc.) Sex Categories Beneficiaries are classified as Male and Female. Only a few beneficiaries had missing sex, and all were Racelethnicity Categories Race data is not routinely included in VSP enrollment data nor on VSP claims, and therefore race/ethnicity is not included in these analyses States and Territories VSP includes data for every state, but this data is incomplete. An important consideration for VsP data is the source of state data. VSP cannot link enrollment(denominator ) files to individual claims( the source for numerators). Enrollment data is primarily provided by employers reporting employee benefit listings approximately 8% of enrollees do not have a state of residence listed Exams and diagnoses( the source for numerators)are based on the provider's state. This coverage is universal as it is required for processing of the claims

Only a few beneficiaries had missing sex, and all were suppressed.

All data incorporated into the VEHSS system is de-identified summary data VEHSS does not report any patient-level data. To ensure maximum levels of data privacy and security, NORC worked with its internal data governance board, external experts and data providers and the Cms VRDC to design suppression algorithms to balance high level patient protection while maintaining the utility of publicly released data. Currently, VEHSS employs the following data suppression algorithm for 1. Suppress rates and denominator when denominator 11 2. Suppress rates if numerator <3 and denominator 30 3. Report rates to 4 digits, formatting as percentage with two decimal points 4. For public data on the vess data Visualization Application and cdc open Data Platform nominators are rounded to the nearest 100
