The High Direct Medical Costs of Prader-Willi Syndrome.

OBJECTIVE: To assess medical resource utilization associated with Prader-Willi syndrome (PWS) in the US, hypothesized to be greater relative to a matched control group without PWS. STUDY DESIGN: We used a retrospective case-matched control design and longitudinal US administrative claims data (MarketScan) during a 5-year enrollment period (2009-2014). Patients with PWS were identified by Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code 759.81. Controls were matched on age, sex, and payer type. Outcomes included total, outpatient, inpatient and prescription costs. RESULTS: After matching and application of inclusion/exclusion criteria, we identified 2030 patients with PWS (1161 commercial, 38 Medicare supplemental, and 831 Medicaid). Commercially insured patients with PWS (median age 10 years) had 8.8-times greater total annual direct medical costs than their counterparts without PWS (median age 10 years: median costs $14 907 vs $819; P < .0001; mean costs: $28 712 vs $3246). Outpatient care comprised the largest portion of medical resource utilization for enrollees with and without PWS (median $5605 vs $675; P < .0001; mean $11 032 vs $1804), followed by mean annual inpatient and medication costs, which were $10 879 vs $1015 (P < .001) and $6801 vs $428 (P < .001), respectively. Total annual direct medical costs were ∼42% greater for Medicaid-insured patients with PWS than their commercially insured counterparts, an increase partly explained by claims for Medicaid Waiver day and residential habilitation. CONCLUSION: Direct medical resource utilization was considerably greater among patients with PWS than members without the condition. This study provides a first step toward quantifying the financial burden of PWS posed to individuals, families, and society.

Mass Screening for Severe Problem Behavior among Infants and Toddlers In Peru.

INTRODUCTION: Severe behavior problems among people with intellectual and developmental disabilities (IDD) are a major barrier to integration in the community. Recent research suggests that these behaviors often begin very early in life and might be prevented by early identification and intervention (Rojahn, Schroeder, & Hoch, 2008). The current paper presents a method of mass screening for early signs of severe behavior problems among infants and toddlers in Peru. METHODS: A Parental Concerns Questionnaire (PCQ) which asks 15 questions, each related to a risk factor for severe behavior problems, based on past research on IDD, was used by veteran parents to interview 341 new parents who had been solicited by TV, radio, and public service announcements across the country. Of these, 262 were recruited and enrolled in a longitudinal study in which they will be followed for 12 months, to see if at-risk children actually will develop severe behavior problems. An extensive initial interdisciplinary evaluation was given to each child. Consumer satisfaction questionnaires were given to the parents as to their attitude toward the screening method. RESULTS: Data from the Interdisciplinary Evaluations of the sample suggest a very high hit rate (96%) by the screening instrument (PCQ). Consumer satisfaction was 98%, suggesting that the method was tolerated well by parents. DISCUSSION: The PCQ is a brief and efficient method to screen infants and toddlers at risk for severe behavior problems. The data also suggest that parents suspect these problems at a very early age. Early intervention thus seems a feasible strategy to intervene before these problems become deeply ingrained as children develop.
