Evaluating the appropriateness of red blood cell transfusions: the limitations of retrospective medical record reviews.
Several studies have looked at the appropriateness of red blood cell transfusions, using retrospective chart reviews to assess compliance with guidelines. The goal of this study was to determine the quality of medical chart documentation, and assess the validity and the feasibility of using retrospective chart review data as part of a quality improvement (QI) program, to evaluate the appropriateness of peri-operative transfusions. ⋯ Only 68% of post-operative transfusion events on the day of surgery and 35% of transfusion events on days after surgery were accompanied by documentation of blood loss and/or change in vital signs. Symptoms were recorded in only 10% of post-operative transfusion events. The rationale for transfusion was recorded in only 16% of post-operative transfusion events on the day of surgery, in 27% on post-operative days and in 95% of intra-operative transfusions. The documentation of rationale was not different for transfusion events involving autologous blood (31%) or allogeneic blood (32%). This study provided information on transfusion practices. Single unit transfusions occurred in only 47 and 34% of patients receiving autologous and allogeneic blood, respectively. Only 19% of patients transfused with more than one allogeneic blood units, were clinically reassessed between blood units, compared to 34% of patients receiving more than one autologous blood unit. We conclude that retrospective chart reviews are limited by inadequate documentation and may not be the optimal source of information to determine the appropriateness of a transfusion. Improved methods (e.g. prospective reviews, or other system-level data collection methods) are needed for QI programs to influence practice. Despite its limitations, the information obtained suggests that current practice could be improved.

Factors associated with inappropriate emergency hospital admission in the UK.
This paper reports an attempt to assess the factors associated with inappropriate acute hospital admission using the technique of logistic regression. Data were obtained from two separate studies of acute hospital utilization in south-west England, conducted between 1992 and 1994. The appropriateness of admission was assessed using explicit standardized criteria in the form of the intensity-severity-discharge review system with adult criteria (ISD-A). ⋯ For one centre, the final model contained age/ specialty and use of community services. For the other, the final model contained two measures of health status on admission-coping failure and admission with stroke. It is concluded that the complex interplay between the characteristics of patients, referrers, alternative forms of care and the acute hospital may result in quite different types of inappropriate admissions in different locations.
