1 Student Guide Module 2: Preventive Medicine in Humanitarian Emergencies Civil War Scenario Problem based learning exercise objectives Identify the key elements for the assessment of a population following a disaster. Determine the needs of the affected population. Use the surveillance cycle. Identify the main modes of disease transmission for the displaced. Establish the intervention priorities in a disaster situation. Develop intervention strategies according to the disaster situation Case Scenario: Relocation due to rebel violence and civil war Increasing fighting between rebel and government forces in a remote mountainous region has displaced many of the people living in the villages to camps at a lower elevation. As the fighting intensifies more families arrive at the camp, which now has over 10,000 people. Among the new arrivals are children and adults who have serious injuries from being trapped between the warring armies. Many of the women and girls have been raped by the soldiers. The government has declared a humanitarian emergency and a Health Emergency Operations Center (HEOC) has been established in the Ministry of Health (MoH), which is led by the Disaster Coordinator. You have been asked by the coordinator to organize a team to fly to the area by helicopter and carry out a rapid assessment to determine how best to respond to the situation. 1) What type of personnel need to be a part of this assessment team? (2 min) Scenario continued: On arrival at the camp you note several NGOs who have already been working in the country have responded by bringing in tents and food. However, the recent arrivals have overwhelmed the available resources. There are now over 10,000 people in the camp. There are several clinics that has been set up by the NGOs and 1 ambulance, which must drive 5 hours to reach the nearest hospital. Cases of malaria are being diagnosed at the clinic and there is concern because this population has no immunity because malaria is not a problem in their villages at a higher altitude. People are defecating in a nearby river, which most people are also using for

2 drinking water. There is almost no security in the camp and many families are frightened. You have a satellite phone and file your first report to the disaster coordinator even before beginning your structured assessment. 2) What are the most immediate needs? (3 min) Scenario continued: You assign members of your team to carry out a rapid population assessment and emergency need assessment. For each they need to complete a chart that has been developed as a tool for these assessments. The emergency (rapid) need assessment helps determine basic population needs and resources in order to meet those needs. It also helps identify gaps between needs and available resources, which are outlined below. 3) What are the major areas and their key elements that need to be included in the population assessment chart? (5 min) 4) What are the major areas and their key elements that need to be included in the emergency (rapid) needs assessment chart? (10 min) Scenario continued: (5 min) Scenario continued: 2 weeks after your rapid assessment report was filed you return to the area with a mobile health assessment team to conduct a rapid, two-hour assessment. You visit the camp and a clinic. The area of the camp is 200 square meters. In the camp families and friends seem to be arranged together and share cooking fires. The fuel source appears to be wood from a nearby jungle. The area is extremely smoky because of the large number of open fires. You first meet with an aid worker who is helping to organize the camp and the 2 doctors and 4 nurses who provide care at the medical clinic. You find that they have conducted a census and gathered the following demographic data: Total Population 0-4 years 5-15 years >15 years Total Male Fem Total Male Fem Total Male Fem Total Male Fem

3 There are 360 known pregnant women; an unknown number of unaccompanied children, and a total of 630 people older than 60 years 440 of these are women and 190 are men. Injured people are mostly children with burns or trauma. There is neither electricity nor running water. The nurses have a small stock of basic medications and clinic supplies as well as a centrifuge for measuring hemoglobin and a microscope. There is a small number of malaria rapid diagnostic test kits. The nurses report that they have primarily now been seeing children with diarrhea, fever, cough, and other respiratory symptoms. They still see new arrivals with serious injuries from the war. There have been a number of deaths reported: 20 victims from war injuries and 10 newborns and young infants with respiratory symptoms. All the clinics are recording patients and the presumed diagnosis or chief complaints on paper. The people in the camp were small farmers and herdsmen with almost no access to health care. Childhood malnutrition rates were quite high. Immunization rates were less than 30%. Water is supplied by carrying water from the river in buckets and other containers. Boiling is the only safe and available water treatment, but most people are not doing this because of the difficulty and fuel scarcity. Not enough latrines have been built and women complain that they do not feel safe going to the latrines. As a result many defecate in the river and streams near the tents. Garbage is either burned or dumped outside the tents. Food is mostly cassava or mush prepared from emergency stores that have arrived irregularly by truck. Food is supplemented by supplies families brought with them. There is no consistent food distribution system, with people grabbing whatever they can when a supply arrives. The nurses suspect that the elderly and single mothers are particularly at risk for not getting food from the emergency supplies. Food is prepared by individual family groups using available water and cooking over open fires. Some people do not have access to a fire or equipment to cook and are eating uncooked mush. There is little or no soap. Despite the smoke, flies and mosquitoes are present. Children going into the jungle to search for food risk snake bites. There is no particular order in the tent city with families and friends banding together to protect each other, but no security forces or organized leadership.

4 5) What modes of disease transmission are potentially the most important in this camp? Case progression: Conducting surveillance and making quick decisions After completing your assessment of the camp and health care center you suggest that the nurses and community health workers (CHW) establish a surveillance system by keeping a log of all patient encounters, births, deaths, arrivals and departures in the camp. You would like to review it after 1 week. During that week some additional bulk food supplies were delivered to the camp, but little else has changed. One week later you collect the log and use it to complete the Weekly Surveillance Reporting Form you intend to submit to the Ministry of Health (MoH) regional disaster coordinator. Divide into 2 groups and review either log A or B 6) Identify the 4-5 most significant public health concerns based on the information in the weekly surveillance reporting form (log A or B). (10 min + 5 min discussion) 7) Prioritize these concerns according to which are most likely to result in the greatest amount of preventable mortality if not immediately addressed. (10 min) 8) What are the most feasible intervention strategies to address the most significant health concerns you identified in the exercise? (10 min)

5 Handout 1 Based on the acquired knowledge, identify the key elements of the population assessment. Demographics - Total number of people in population - Population Structure: Age groups (0-4, 5-15, >15 years) and sex - Vulnerable Groups: Pregnant and Lactating Mothers, children <5years,unaccompanied children, elderly and injured Pre-disaster health conditions - Prevalence of chronic diseases, malnutrition rates, prevalence of infectious diseases, vaccination coverage and access to health care

6 Healthcare system evaluation - Physical condition of buildings and durable medical equipment - Numbers and types of health workers - Non-durable supplies and medications - Condition of electricity, clean water and sewerage at healthcare facilities - Is surgical or in-patient care possible? - Condition of cold chain and vaccines - Is a system of disease surveillance functioning? Condition of other community resources - Physical condition of buildings and durable medical equipment - Numbers and types of health workers - Non-durable supplies and medications - Condition of electricity, clean water and sewerage at healthcare facilities - Is surgical or in-patient care possible? - Condition of cold chain and vaccines - Is a system of disease surveillance functioning?
