A computer-assisted health care cost management system.
To our knowledge, First Chicago has developed and implemented the first operational integrated health data computer system that includes the traditional occupational medicine data base together with medical claims and health risk appraisal data. OMNIS has combined medical claims, personnel, disability, employee assistance program, wellness program participation, administrative functions, laboratory, periodic health evaluation data, and health risk appraisal data in a single system. OMNIS provides data that are being used to more accurately predict health care and disability costs and design intervention strategies. Clearly, the integrated health data computer system provides information to manage increasingly complex issues of health care quality and cost. For companies concerned about the quality as well as the cost of health care, an integrated health data computer system (OMNIS) may be a valuable tool to objectively assess quality of care. For example, a company could evaluate how effectively various providers (eg, health maintenance organizations, preferred provider organizations, indemnity plan) control medical conditions such as hypertension. Integrated health data management systems have the potential to assist in the selection of the highest quality and most cost-effective health care plans.

Quality and cost-effective management of mental health care.
Corporations have reduced their mental health care benefits by limits on coverage for such services. We report on a comprehensive mental health care program, including prevention and early intervention, hospital utilization review, and consulting psychiatrist, which has improved the quality and has significantly reduced inpatient insurance psychiatric hospitalization costs. Mental health service coverage was actually enhanced. Inpatient psychiatric hospitalization costs 12 months before and after the implementation of a concurrent psychiatric hospital utilization review program were reviewed for a major corporation. Total hospital days and average length of stay decreased by 43% whereas total inpatient psychiatric hospital charges decreased by $309,518. Total inpatient days decreased by 1045. Quality and cost-effective comprehensive psychiatric health care services can be offered by major corporations providing that such benefits are carefully designed and managed.

Evidence that discrimination against ergocalciferol by the chick is the result of enhanced metabolic clearance rates for its mono- and dihydroxylated metabolites.
Studies on the discrimination between ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3) by chickens have led to conflicting conclusions. To investigate this problem in more detail, radiolabeled vitamin D and vitamin D metabolites were administered intravenously, which allowed determination of their relative plasma clearance rates. The study involved three groups of adult male chickens (five per group). Birds in group 1 were co-dosed with [3H]vitamin D2 and [3H]vitamin D3. Birds in group 2 were co-dosed with [3H]25-dihydroxyvitamin D2 and [3H]25-dihydroxyvitamin D3 and birds in group 3 were co-dosed with [3H]1,25-dihydroxyvitamin D3 and [3H]1,25-dihydroxyvitamin D2. The results indicated that the plasma turnover rate of [3H]vitamin D2 is 1.5 times faster than that of [3H]vitamin D3. Plasma turnover of the 25-hydroxylated metabolites differed, with [3H]25-dihydroxyvitamin D2 clearing faster (11 times) than [3H]25-dihydroxyvitamin D3. The largest difference appeared in the 1,25-dihydroxyvitamin D2 turnover rates with 1,25-dihydroxyvitamin D2 clearing approximately 33 times faster then [3H]1,25-dihydroxyvitamin D3. These data, therefore, indicate that discrimination against vitamin D2 sterols in the chick occurs primarily between steps in the metabolism of vitamin D and not at the point of metabolism or excretion of the parent vitamin.

Suppression of mitogenic response of bovine lymphocytes during experimental ketosis in calves.
Experimental ketosis was induced by feeding calves a diet containing 1,3 butanediol for 9 or 10 days. Blood beta-hydroxybutyrate was significantly (P less than 0.05) elevated during clinical ketosis. The mitogenic response of the lymphocytes collected during ketosis was significantly (P less than 0.01) suppressed, and the suppression persisted for 2 weeks. During ketosis, all calves fed a 1,3 butanediol diet had clinical signs of an upper respiratory tract infection. Possible relationships between the suppressed function of lymphocytes, the increased concentration of 1,3 butanediol, and the increased susceptibility of the calves to infections during ketosis were considered.
