The tomato Mi-1 gene confers resistance to both root-knot nematodes and potato aphids.

Mi-1, a Lycopersicon peruvianum gene conferring resistance to the agricultural pests, root-knot nematodes, and introgressed into tomato, has been cloned using a selective restriction fragment amplification based strategy. Complementation analysis of a susceptible tomato line with a 100 kb cosmid array yielded a single cosmid clone capable of conferring resistance both to the root-knot nematode Meloidogyne incognita and to an unrelated pathogen, the potato aphid Macrosiphum euphorbiae. This resistance was stable. The Mi-1 gene encodes a protein sharing structural features with the nucleotide-binding site leucine-rich repeat-containing type of plant resistance genes.

Performance reporting of health care delivery systems: will it make the grade?

Recently, federal governments, state governments, and private sector groups have begun initiatives that would report the performance of health plans in key areas. United HealthCare Corporation's experience in developing and publicly releasing "report cards" for 15 of its health plans may prove useful as other efforts go forward. There are both advantages and challenges to producing a report card in terms of resource investment, directing health plans toward performance improvement, and the ability for both purchasers and policy makers to understand and make use of results. These and other issues will be important to consider as other segments of the health care industry, particularly providers, focus on reporting performance measures.

Quality screening and management using claims data in a managed care setting.

Quality screening and management (QSM), developed by United HealthCare Corporation for its own health plans but applicable to other settings, analyzes health care provided to an enrolled population using claims and administrative data supplemented, when necessary, with medical record review. For selected topics/conditions, QSM compares the care received by patients to that recommended by established practice guidelines and also reports and describes quality through incidence rates, condition-specific process and outcome measures, occurrence of adverse events, and use of preventive services. Results of the analyses are linked to appropriate quality management actions and are used to identify strategies for improvement. Data permit health plans to make performance comparisons on individual indicators and longitudinal comparisons on the effectiveness of quality improvement initiatives.

Findings from the Medicaid Competition Demonstrations: a guide for states.

The Medicaid Competition Demonstrations were initiated in 1983-84 in six States (California, Florida, Minnesota, Missouri, New Jersey, and New York). State experiences in implementing the demonstrations are presented in this article. Although problems of enrolling Medicaid recipients in prepaid plans or with primary care case managers under these demonstrations proved challenging to States, lessons were learned in three key areas: program design and administration, health plan and provider relations, and beneficiary acceptance. Therefore, States considering similar programs in the future could benefit from these findings.
