To develop a common structure for reports on health crises and critical health events guidelines have recently been published (Kulling et al 2010). They try to capture the experiences gained and for promoting a standardized methodology for sharing results and lessons. If future reporting follows common standards, then the documented findings would be comparable and could be used to learn and apply lessons within an individual field of activity and to apply those lessons learned also to other related preparedness activities. It could also facilitate the implementation of joint activities and joint reports involving different sectors. The development of this proposed method for common reporting on health crises and critical health events has been derived mainly from the following processes: (i) Health Disaster Management: Guidelines for Evaluation and Research in the Utstein Style; (ii) the Swedish Disaster Medicine Study Organization (KAMEDO); (iii) the Swedish Emergency Management Agency network of observers; (iv) the WHO Regional Office for Europe project (supported by the EU Health Programme) ‘Support Health Security, Preparedness Planning and Crisis Management in the EU, EU accession and neighboring (ENP) countries’ including expert consultations. The guidelines include the following headlines: Title, Preface, Authors, Executive Summary, Introduction/Material/Methodology, Pre-Event Status (Background, Preparedness, Hazard(s)involved, Risks, Vulnerability, Resilience), Health Crises and Critical Health Events (Damage, Consequences of Damage (Changes in Functions/Disturbances), Responses (Relief Responses, Recovery Responses), Development, Discussion, Lessons Identified and Actions Recommended, Conclusions, References, Appendices, Keywords, Index, Abbreviations. Pilot testing is suggested followed by an extensive review process. The guidelines should be supplemented further with determinants and indicators when the guidelines are used for in depth reporting to evaluate crisis response operations.
