A Survey of Asthma Care in Managed Care Organizations: Statistical AnalysisStatistical Analysis
Descriptive statistics are presented. Because of the small number of actual responses, no inferential statistics were assessed. For the purpose of this report, the term “very few” is used to describe responses reported by < 20% of the respondents, “minority” refers to 20 to 49%, “majority” refers to 50 to 79%, and “nearly all” refers to 80 to 100% of the respondents. Although information on all three types of insurance products is presented, this report will primarily focus on responses for the two types of capitated care, staff model and nonstaff model plans. All analyses were conducted using computer software (SAS Version 6.12; SAS Institute; Cary, NC). my canadian pharmacy

The study was conducted under the approval of the Institutional Review Board serving Rush-Presbyterian-St. Luke’s Medical Center.
Selected General Health Plan Characteristics
Of the 19 eligible MCOs, 13 responded, for a response rate of 68.4%. It is estimated that these 13 MCOs accounted for 83.0% of the capitated care in the region (estimates based on 1997 Illinois state enrollment of the surveyed MCOs; data provided by the Illinois Medical Society). All but one of the respondents was the medical director of the organization. Regarding the differing plans within the overall organization, 3 of the responding MCOs (23.1%) had a staff model plan, 11 (84.6%) had a nonstaff model capitated plan, and 6 (46.2%) had some type of noncapitated plan.
Table 1 describes some of the characteristics of the plans within the MCOs. At the time of the survey, two of the three staff model plans had an enrollment of > 50,000 members, whereas nearly 64% of the nonstaff model capitated plans had < 50,000 members. Only one of the three staff model plans enrolled Medicaid recipients, vs 9.1% of the nonstaff model plans; in contrast, all three of the staff model plans enrolled Medicare recipients vs 27.3% of the nonstaff model plans.
