Background: Medicaid-insured asthmatic children frequently use emergency rooms (ERs). The reasons are unclear and have predominantly been studied in inner-city populations.Methods: We used billing data and focus groups to clarify reasons for frequent ER use by Medicaidinsured children with asthma living in rural areas and 23 towns in Kansas.Results: High ER utilization was concentrated in a small percentage of provider practices and children with asthma. Parents expressed strong preference for primary care treatment, and identified real or perceived difficulties in using primary care as the principal reasons for ER use. Difficulties included trouble contacting primary care physicians or obtaining urgent appointments, limited continuity of care, practice systems poorly adapted to patient needs, a perception that physicians preferred patients to use emergency services, and difficulties in obtaining medications. Parents were not aware of preventive measures or case management but reported high interest in these. Parents did not recall provider discussion of asthma risk factors/preventive strategies during primary care visits, although all children with high ER utilization had multiple risk factors, including exposure to high levels of household smoking.Conclusions

Improving Medicaid program effectiveness for underserved populations is hampered by low survey response rates. This study determined how to maximize Medicaid consumer satisfaction survey response rates to the Consumer Assessment of Health Plans Study (CAHPS) survey. In a public immunization clinic, 8 focus groups and 15 extended interviews were used to assess consumer-preferred survey design features and incentives. To test hypotheses, we conducted the following trial. Out of 10,733 total participants in a Kansas Medicaid managed care plan, 3,685 eligible for CAHPS were unduplicated by household. After randomization of the 968 households with valid addresses to one of three groups, a controlled trial was conducted to assess response rates to CAHPS survey formats and incentives. Response rates were 35% for a standard mailing, 44% for a user-friendly low-literacy mailing, and 64% for a user-friendly low-literacy mailing with a $10 contingent incentive. Both experimental arms significantly improved response compared with the control; the response rate of the mailing group with the incentive was higher than the response rate of the group receiving that mailing without any incentive (p<0.0001). Using consumer-based preferences significantly increased response rates to this Medicaid satisfaction survey. Raising CAHPS response rates may increase validity of Medicaid consumer satisfaction information.

In this paper, key barriers to providing smoking cessation services for low income individuals are illustrated using epidemiologic data from a population which was enrolled in a Medicaid managed care plan in Kansas during 1998. The Plan served 623 pregnant women who could potentially benefit from assistance in avoiding tobacco exposure. The prevalence of smoking among adult clients was 44.8%. twice the national average. Only 52.3% of adult smokers were advised by a provider to quit in the previous year. Most individuals in the client population (81.7% of the 10,733 members) were children, suggesting the importance of targeting environmental tobacco smoke exposure in order to reduce morbidity from asthma. The adult household member who needed smoking cessation services, however, was unlikely to qualify for health care benefits through Medicaid. The median length of enrollment was only 1.9 months, providing very little client contact time for tobacco control initiatives. The literature suggests that some providers may lack skills in treating tobacco as an addiction. It would be a major task for the managed care organization to train the 2,000 physicians in 68 of the 105 counties of Kansas who cared for this population. Potential solutions include improving reimbursement for smoking prevention and treatment, and developing cheaper smoking cessation services which are effective and acceptable among low-income individuals. The managed care organization could provide patient education materials and staff training for physicians and other members of the office staff.
