Factor-implied scales of ward atmosphere.

Evaluation of environments in hospital settings with regard to their therapeutic qualities has been a problem for clinicians and evaluation specialists for sometime. The present project examined the Ward Atmosphere Scale (WAS) factor-analytically and derived second-order factors inconsistent with those proposed by the authors of the scale. Items of the WAS were arranged psychometrically into three scales as implied by the factor analysis. Results suggest that interpretation of the WAS can be simplified considerably if these three super-ordinate dimensions are used to organize item-level data.

Automated blood typing of patients.

The 15-channel Technicon blood typing machine is shown to be equally useful for patient and donor blood typing. It provides increased accuracy as well as increased speed and economy. Test capabilities are broadened by permitting additional simultaneous determinations such as the automated reagin test for syphilis or tests for additional erythrocyte antigens. Automated antibody screening, performed on the blood typing machine in conjunction with patient typing, was found to be of limited use because it failed to detect as much as 60 per cent of some clinically significant antibodies.
