Managers reports of automated coding system adoption and effects on data quality.

OBJECTIVE: Assessment of the adoption of automated classification (encoder) systems in healthcare settings and related effects on perceived data quality. METHODS: Survey of all U.S. accredited medical records managers, summarizing their reports of automated encoding systems and data quality change following adoption of systems. RESULTS: Significant improvement in data was seen from adoption of automated encoding systems, though variation existed across regions and key demographic variables. CONCLUSION: At a national level, there is a need to minimize data quality variation and ensure some degree of nationwide uniformity in the performance of coding systems. If healthcare providers are expected to trust coded data for comparative purposes, there will be a like need for more uniform and standardized system-based performance benchmarks.

Evaluation of an indirect fluorescent antibody test (IFAT) for demonstration of antibodies to Toxoplasma gondii in the sea otter (Enhydra lutris).

An indirect fluorescent antibody test (IFAT) for detection of Toxoplasma gondii infection was validated using serum from 77 necropsied southern sea otters (Enhydra lutris nereis) whose T. gondii infection status was determined through immunohistochemistry and parasite isolation in cell culture. Twenty-eight otters (36%) were positive for T. gondii by immunohistochemistry or parasite isolation or both, whereas 49 (64%) were negative by both tests. At a cutoff of 1:320, combined values for IFAT sensitivity and specificity were maximized at 96.4 and 67.3%, respectively. The area under the receiver-operating characteristic curve for the IFAT was 0.84. A titer of 1:320 was used as cutoff when screening serum collected from live-sampled sea otters from California (n = 80), Washington (n = 21), and Alaska (n = 65) for T. gondii infection. Thirty-six percent (29 out of 80) of California sea otters (E. lutris nereis) and 38% (8 out of 21) of Washington sea otters (E. lutris kenyoni) were seropositive for T. gondii, compared with 0% (0 out of 65) of Alaskan sea otters (E. lutris kenyoni).

Unilateral pleural effusion complicating central venous catheterisation.

Acute respiratory distress developed in two preterm babies because of unilateral hydrothorax secondary to the migration of a central venous catheter into the pulmonary vasculature. Prompt recognition of the problem and rapid treatment are essential and life saving. This complication of intravenous alimentation catheters has not been previously reported in the neonatal age group.
