This new edition of Ann Bowling's well-known and highly respected text has been thoroughly revised and updated to reflect key methodological developments in health research. It is a comprehensive, easy to read, guide to the range of methods used to study and evaluate health and health services. It describes the concepts and methods used by the main disciplines involved in health research, including: demography, epidemiology, health economics, psychology and sociology.The research methods described cover the assessment of health needs, morbidity and mortality trends and rates, costing health services, sampling for survey research, cross-sectional and longitudinal survey design, experimental methods and techniques of group assignment, questionnaire design, interviewing techniques, coding and analysis of quantitative data, methods and analysis of qualitative observational studies, and types of unstructured interviewing. With new material on topics such as cluster randomization, utility analyses, patients' preferences, and perception of risk, the text is aimed at students and researchers of health and health services. It has also been designed for health professionals and policy makers who have responsibility for applying research findings in practice, and who need to know how to judge the value of that research.

results Risk stratification can be used for both congenital and acquired coagulation disorders to assess the susceptibility to bleeding. This risk stratification and an appropriate therapeutic pathway allow for an adequate and individualised therapy for each patient. A central point is the close interdisciplinary cooperation with specialists. In addition to discontinuing or replacing existing treatment modalities, local hemostyptic measures are of primary importance. If local measures are insufficient, systemically administered substances such as desmopressin and blood products must be used.
