Utilization care plans and effective patient data management.

This article introduces the concept of a utilization care plan (UCP) for supporting the communication of data required for effective utilization review and utilization management. Utilization review is a process of measurement that compares the performance of a ward, department, or entire facility against accepted criteria to identify resource use shortfalls. Utilization management is the deliberate action by third party payers to ensure that shortfalls in resource utilization are minimized. Critical to the success of utilization management is effective data communication; utilization review data must be accurate, complete, accessible, timely, and coordinated. Computer-based UCP systems can remind caregivers when and what services should be provided to patients and also monitor the portion of those services that should be administered during each phase of a patient's therapy. Deviations from the UCP system template constitute variances that can be documented and highlighted in a friendly automated system that ensures highly accurate and extremely timely concurrent utilization information. Some implications of using UCP systems for future research and practice are also discussed.

Pharmacokinetics of ciprofloxacin in subjects with varying degrees of renal function and undergoing hemodialysis or CAPD.

The pharmacokinetics of a single, oral dose of 750 mg of ciprofloxacin were studied in 35 subjects with various degrees of renal function (Group 1, Clcr > or = 80 ml/min; Group II, Clcr 50-79 ml/min; Group III, Clcr 10-49 ml/min) and on hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD). Blood, urine and CAPD dialysate samples were collected over a period of 48 hours after dosing. Data were fitted using non-linear, least squares regression. The mean Cmax was 3.4 +/- 1.0 mg/l and tmax was 2.3 +/- 0.9 hours. The mean AUC in Group I was 14.7 mg.h/l, Group II was 33.7 (p < 0.001), Group III 63.8 (p < 0.001), HD 57.9 (p < 0.0001) and CAPD 44.3 (p < 0.001). Half-life in Group I was 4.6 h, and was shorter than Group III (11.1 h, p < 0.001), HD (13.4 h, p < 0.001) and CAPD (8.9 h, p < 0.001). Total body clearance and renal clearance demonstrated significant differences also. The dialysis clearance in CAPD patients was 0.53 +/- 0.39 l/h. Peritoneal effluent concentrations varied from 0.6 mg/l during the first exchange, to a peak of 2.2 mg/l during the second, to 0.13 mg/l in the 48 hour (9th) exchange. Dosage adjustments of ciprofloxacin in the presence of renal insufficiency are indicated for subjects with a Clcr < 20 ml/min/1.73m2.

Evaluation of impairment of the upper extremity.

Evaluation of impairment of the upper extremity is the product of a team effort by the physician, occupational therapist, physical therapist, and rehabilitation counselor. A careful recording of the anatomic impairment should be made because this is critical in determining the subsequent functional activities of the extremity. The measurement criteria for clinical and functional evaluation includes condition assessment instruments. Some assess the neurovascular system, others assess movements including the monitoring of articular motion and musculotendinous function. Sensibility assessment instruments measure sympathetic response and detect single joint stimulus, discrimination, quantification, and recognition abilities. A detailed description of each assessment is recorded and physical capacity evaluation is only one component of the entire vocational evaluation. This evaluation answers questions regarding the injured worker's ability to return to his previous job. The work simulator is a useful instrument that allows rehabilitation and testing of the injured upper extremity. Job site evaluation includes assessment criteria for work performance, work behavior, and work environment.
