HIGHLIGHTS

  • For 36 of 44 quality measures calculated, performance did not differ between the statewide Medicaid managed care population and the population of individuals with developmental disabilities who were voluntarily enrolled in a Medicaid managed care plan during 2013.
  • Management of asthma medications among the adolescent population with developmental disabilities was 13 percentage points better than the statewide average for both the 50% and 75% "days covered" measures.
  • Chlamydia screening and nephropathy monitoring for diabetics among the population with developmental disabilities were at least 20 points worse than the statewide average.
  • Measures addressing testing for diabetes, monitoring specific medications in adults, appropriate treatment for upper respiratory infections in adults and pharyngitis in children, and compliance with annual dental visits among children, had a significant gap in performance and appear ripe for improvement as the DD population transitions into a capitated model.

Over 110,000 Medicaid recipients in New York State (NYS) are currently identified as living with developmental disabilities (DD), such as intellectual disabilities, cerebral palsy, Down syndrome, and autism spectrum disorders. Medicaid benefits for these individuals have traditionally been delivered under a Fee-for-Service (FFS) payment system through four distinct state agencies: the Office for People with Developmental Disabilities (OPWDD), the Department of Health (DOH), the Office of Mental Health (OMH), and the Office of Alcohol and Substance Abuse Services (OASAS). Upon approval of the People First Waiver through the Center for Medicare and Medicaid Services (CMS), OPWDD will begin to transition DD services into capitated managed care models known as Developmental Disabilities Individual Support and Care Coordination Organizations (DISCOs). Eventually, Medicaid recipients requiring DD services will be mandatorily enrolled in DISCOs statewide. The DISCO benefit package will initially include all waiver services currently provided by OPWDD, as well as long-term care, and behavioral health. Acute care services (including emergency room and physician visits, inpatient care, and pharmacy) will continue to be paid for through Medicaid FFS and added to the DISCO benefit package in the future. While the transition to capitated, managed care offers the potential for substantial cost savings through more efficient delivery of care, a critical question is whether the quality of and satisfaction with care will also improve.

The NYS DOH currently oversees capitated Medicaid managed care (MMC) plans including "mainstream" MMC, the comprehensive and traditional health plan model with a benefit package that covers acute, chronic, and preventive care services. Home and Community Based waiver Services (HCBS) provided by OPWDD, including habilitation services, respite care, service coordination, and adaptive technologies, are currently excluded from mainstream MMC. Enrollment of individuals living with DD into MMC is currently voluntary. While DISCOs will offer a benefit package very different than that provided by MMC plans, the quality of managed care performance will largely be evaluated following reporting requirements of MMC, with additional DD-specific measures incorporated as necessary.

As a way to measure the quality of care, the DOH has been collecting performance data from its MMC plans through its Quality Assurance Reporting Requirements (QARR) initiative since 1994. QARR is largely based on the National Committee on Quality Assurance (NCQA) measures, plus additional measures developed by the DOH to monitor the delivery of primary and chronic care services. At this time, NYS´s QARR publications do not present DD performance separately.

The purpose of this report is to present QARR performance data specific to the DD population voluntarily enrolled in MMC during 2013, to establish an understanding of MMC plan performance in delivering care to this population and identify variation in the quality of care received between the DD population and statewide MMC. For this analysis, the DD population was defined as those individuals eligible for ongoing residential, day, case management, or HCBS overseen by OPWDD. A small portion of the eligible population was not actively receiving OPWDD services in 2013 but would nevertheless be eligible to receive those services if they choose.

Data for this analysis were extracted from New York State´s Medicaid Data Warehouse (MDW), the Office of Health Insurance Programs (OHIP) Data Mart, and QARR member-level data files. The MDW is the data repository for all Medicaid claims, encounters, reimbursement, and member profile information. Data in the MDW are submitted by Medicaid providers and health plans throughout the year, per requirements set forth by the DOH. The OHIP Data Mart is a collection of data tables that have been compiled for use by DOH researchers and program administrators. Tables in the OHIP Data Mart are refreshed on a monthly basis with new data from the MDW. QARR member-level data are submitted annually by health plans and contain the Medicaid Client Identification Number (CIN) and numerator and denominator compliance for each QARR measure.

For this analysis, Medicaid enrollees qualifying for DD services were identified within the MDW using the Restriction Exemption Code. This code categorizes a Medicaid enrollee´s qualifying condition or situation allowing for exemption from mandatory enrollment into MMC. Member CINs with a Restriction Exemption Code equal to 95 (RE95), designating an individual's eligibility to receive ongoing residential, day, case management, or HCBS overseen by OPWDD, were extracted from the MDW. The list was then matched to Medicaid eligibility files contained in the OHIP Data Mart to analyze enrollment characteristics, such as payer, product, and duration of continuous enrollment. The CINs were then matched against the 2014 QARR member-level file to identify those individuals eligible for QARR measures during the 2013 measurement year. Demographic information on those eligible for at least one QARR measure was obtained from the Data Mart. Performance on specific QARR measures was calculated using the member- level files. Performance rates were not calculated for any measure with fewer than 30 individuals. The rates were compared to the statewide average (SWA) for each measure, as calculated based on MMC plan QARR data, inclusive of the DD population. All analyses were completed in SAS 9.3.

A total of 111,880 DD individuals were initially identified as eligible for Medicaid benefits during the 2013 calendar year, with 108,978 (97.4%) enrolled. Of those enrolled, 14,244 (13.1%) voluntarily had their care managed by a mainstream MMC plan at some point during the 2013. The member-level-file revealed that 7,998 (56.1%) of those individuals qualified for QARR measurement in 2013, based on measure denominator specifications. The vast majority of these individuals, 6,788 (84.9%), were eligible for Supplemental Security Income (SSI). Only 18 (0.2%) were dually eligible for Medicare and Medicaid.

As seen in Table 1, the enrolled population was 60.2% male, 48.9% white, 58.8% children between five- and 17 years of age, and primarily residents of Western Region (30.2%) or New York City (NYC) (28.0%). Performance for 44 QARR measures from the 2013 measurement year are presented in Table 2. The eligible DD population for most measures was relatively small, thus resulting in large confidence intervals around many rate calculations. Rates were not calculated for 23 additional measures found to have a sample size less than 30 (Table 3).

Few significant differences were seen between performance among the statewide population and the DD population. There were only four measures for which performance was observed to be better than the statewide average, and of those, two were addressing medical management of asthma in the child and adolescent population. There were eight measures for which performance was significantly worse than the statewide average, two of which are components of the Comprehensive Diabetes Care measure.

Variability in performance outcomes was notable for medication management. While the annual monitoring of patients on persistent anticonvulsants (75%) was eight points better than the statewide average (67%), the combined rate for monitoring persistent medications (anticonvulsants, ACE inhibitors/ARBs, Digoxin, and Diuretics- 84%) was seven points below average (91%). Adherence to antipsychotic medications for individuals with schizophrenia (72%) was significantly better than statewide (63%), but follow-up care for children prescribed ADHD medication in the initiation phase (49%) was significantly worse (statewide average 56%). Follow-up care in the continuation phase was not statistically different from statewide, but still represented a nine-percentage point performance gap (56% compared to 65% statewide). Management of asthma medications among the adolescent population with developmental disabilities was 13 percentage points better than the statewide average for both the 50% and 75% "days covered" measures, while differences on these measures across the adult populations were not statistically different.

While the annual dental visit measure for enrollees between 19 and 21 years of age (46%) was not significantly different from the statewide average (44%), this measure was worse for those between 2 and 18 years of age (58% in the DD population compared to 61% statewide). Appropriate testing for pharyngitis (81%) and appropriate treatment for upper respiratory infections (89%) were significantly worse than statewide averages (87% and 92%, respectively).

Both nephropathy monitoring (63%) and the composite diabetes testing (37%) measures were more than 10 points below the statewide population performance (83% and 51%, respectively), the former a full 20 points below.

Among the vast majority of measures, significant differences in performance between the statewide and DD populations were not observed. This observation is encouraging especially in light of the fact that NYS´s Medicaid managed care population consistently outperforms national averages. Assessment of plan performance for the DD population is currently difficult to reliably quantify in light of small sample sizes for many of the measures; the confidence intervals for most measures were large.

This first look at these performance data suggests potential shortfalls that may need to be discussed. It should be noted that compared to the overall MMC population, the DD MMC population tends to be more white, male, and with a higher percentage residing in the Western Region of NYS as compared to NYC. While it is the policy of the DOH not to risk adjust QARR process measures based on demographic characteristics when evaluating health plan performance, there are historical differences in performance within the subpopulations of MMC that may be impacting these results. In particular, Western NY performance has remained steady while NYC and other regions of NYS have continued to improve.

Continued monitoring of DD MMC performance will be of interest while the previously exempt DD population is slowly integrated into a managed care model. As the eligible population increases in number, evaluation of quality performance will become more reliable, and allow for targeted improvement efforts. DOH will continue to actively work with OPWDD and other stakeholders on quality improvement activities within the MMC subpopulations as part of the State´s Medicaid managed care Quality Strategy.

It is worth noting that a DD population voluntarily enrolled in MMC may be inherently different from those individuals who received services through Medicaid FFS. We do not have comparable data for those individuals in FFS. Small sample sizes existed for many of the measures.
