The public health dimension of disasters--health outcome assessment of disasters

Abstract

A broad range of health problems are related to disasters. Insight into these health problems is needed for targeted disaster management. Disaster health outcome assessment can provide insight into the health effects of disasters. During the 15th World Congress on Disaster and Emergency Medicine in Amsterdam (2007), experts in the field of disaster epidemiology discussed important aspects of disaster health outcome assessment, such as: (1) what is meant by disaster health outcome assessment?; (2) why should one conduct a disaster health outcome assessment, and what are the objectives?, and (3) who benefits from the information obtained by a disaster health outcome assessment? A disaster health outcome assessment can be defined as a systematic assessment of the current and potential health problems in a population affected by a disaster. Different methods can be used to examine these health problems such as: (1) rapid assessment of health needs; (2) (longitudinal) epidemiological studies using questionnaires; (3) continuous surveillance of health problems using existing registration systems; (4) assessment of the use and distribution of health services; and (5) research into the etiology of the health effects of disasters. The public health impact of a disaster may not be immediately evident. Disaster health outcome assessment provides insight into the health related consequences of disasters. The information that is obtained by performing a disaster health outcome assessment can be used to initiate and adapt the provision of health care. Besides information for policymakers, disaster health outcome assessments can contribute to the knowledge and evidence base of disaster health outcomes (scientific objective). Finally, disaster health outcome assessment might serve as a signal of recognition of the problems of the survivors. Several stakeholders may benefit from the information obtained from a disaster health outcome assessment. Disaster decision-makers and the public health community benefit from performing a disaster health outcome assessment, since it provides information that is useful for the different aspects of disaster management. Also, by providing information about the nature, prevalence, and course of health problems, (mental) health care workers can anticipate the health needs and requirements in the affected population. It is important to realize that the disaster is not over when the acute care has been provided. Instead, disasters will cause many other health problems and concerns such as infectious diseases and mental health problems. Disaster health outcome assessments provide insight into the public health impact of disasters.
