CONCLUDING REMARKS

Findings from this survey show that there is substantial variability in certain coagulation laboratory practices. Although in most cases the response patterns from the large and small hospital respondents were not significantly (P > 0.050) different, several questions solicited significantly different responses from these 2 groups.

To our knowledge, this is currently the only report of a broad and comprehensive survey of nationally based coagulation-specific and general laboratory practices. This survey used 2 different modes of data collection: paper-based and electronic. An inherent limitation of our survey instrument is that responses may not consistently reflect actual practices. Surveys are subject to framing biases which can be reduced (e.g., by pilot testing) but not totally avoided. We believe our results present a representative and accurate snapshot of reported hospital coagulation laboratory practices in 2001.

This report is a descriptive characterization of coagulation-specific and general laboratory practices and makes no attempt to relate specific laboratory practices we have observed to other laboratory- and hospital-specific variables or to clinical and health outcomes of patients and populations. Explorations of such inter-relationships using these survey results and those that have been or may be collected in specific outcome studies will be avenues for further investigation.

Acknowledgment
