Analysis of the literature suggests a correlation between fusion and the development of ASDeg compared to arthroplasty, but this association is dampened by the influence of patient age. There is a stronger correlation between fusion and ASDis compared to arthroplasty. The data supports only a class C recommendation (lowest tier) for the use of arthroplasty to reduce ASDis and disc degeneration compared to arthrodesis.

OBJECTIVES: A randomized controlled trial evaluated the impact of feedback and financial incentives on physician compliance with cancer screening guidelines for women 50 years of age and older in a Medicaid health maintenance organization (HMO). METHODS: Half of 52 primary care sites received the intervention, which included written feedback and a financial bonus. Mammography, breast exam, colorectal screening, and Pap testing compliance rates were evaluated. RESULTS: From 1993 to 1995, screening rates doubled overall (from 24% to 50%), with no significant differences between intervention and control group sites. CONCLUSIONS: Financial incentives and feedback did not improve physician compliance with cancer screening guidelines in a Medicaid HMO.

Improving primary care access and scope of services may reduce ED use. Focusing on systems issues rather than patient characteristics may be a more productive strategy to improve appropriate use of emergency medical care.

Feedback to physicians, with or without financial incentives, did not improve pediatric preventive care in this Medicaid HMO during a time of rapid, secular improvements in care. Possible explanations include the context and timing of the intervention, the magnitude of the financial incentives, and lack of physician awareness of the intervention.

IBD disease severity is the most important predictor of both physical and mental health-related quality of life in patients with this condition despite the presence of other chronic conditions.
