The burden of mental disorders and access to mental health and psychosocial support services in Syria and among Syrian refugees in neighboring countries: a systematic review.

BACKGROUND: Exposure to conflict, violence and forced displacement can increase poor mental health among affected populations. Our aim was to examine evidence on the burden of mental disorders and access to and effectiveness of mental health and psychosocial support (MHPSS) services in Syria and among Syrian refugees in neighboring countries. METHODS: A systematic review was done following systematic review criteria. Twelve bibliographic databases and additional gray literature sources were searched for quantitative and qualitative studies. Descriptive analysis and quality assessment were conducted. RESULTS: Twenty-eight eligible studies were identified, of which two were with conflict-affected populations within Syria. Levels of post-traumatic stress disorder ranged from 16 to 84%, depression from 11 to 49%, and anxiety disorder from 49 to 55%. Common risk factors were exposures to trauma and having a personal or family history of mental disorder. Financial and socio-cultural barriers were identified as the main obstacles to accessing MHPSS care. Evaluations of MHPSS services, albeit from predominantly nonrandomised designs, reported positive treatment outcomes. CONCLUSIONS: The MHPSS burden was high, but with considerable variation between studies. There are key evidence gaps on: MHPSS burden and interventions-particularly for those living within Syria; access and barriers to care; and implementation and evaluation of MHPSS interventions.

Treatment gap and mental health service use among Syrian refugees in Sultanbeyli, Istanbul: a cross-sectional survey.

AIMS: Syrian refugees may have increased mental health needs due to the frequent exposure to potentially traumatic events and violence experienced during the flight from their home country, breakdown of supportive social networks and daily life stressors related to refugee life. The aim of this study is to report evidence on mental health needs and access to mental health and psychosocial support (MHPSS) among Syrians refugees living in Sultanbeyli-Istanbul, Turkey. METHODS: A cross-sectional survey was conducted among Syrian refugees aged 18 years or over in Sultanbeyli between February and May 2018. We used random sampling to select respondents by using the registration system of the municipality. Data among 1678 Syrian refugees were collected on mental health outcomes using the Posttraumatic Stress Disorder (PTSD) Checklist (PCL-5) and the Hopkins Symptoms Checklist (HSCL-25) for depression and anxiety. We also collected data on health care utilisation, barriers to seeking and continuing care as well as knowledge and attitudes towards mental health. Descriptive analyses were used. RESULTS: The estimated prevalence of symptoms of PTSD, depression and anxiety was 19.6, 34.7 and 36.1%, respectively. In total, 249 respondents (15%) screened positive for either PTSD, depression or anxiety in our survey and self-reported emotional/behavioural problems since arriving in Sultanbeyli. The treatment gap (the proportion of these 249 people who did not seek care) was 89% for PTSD, 90% for anxiety and 88% for depression. Several structural and attitudinal barriers for not seeking care were reported, including the cost of mental health care, the belief that time would improve symptoms, fear of being stigmatised and lack of knowledge on where and how to get help. Some negative attitudes towards people with mental health problems were reported by respondents. CONCLUSIONS: Syrian refugees hardly access MHPSS services despite high mental health needs, and despite formally having access to the public mental health system in Turkey. To overcome the treatment gap, MHPSS programmes need to be implemented in the community and need to overcome the barriers to seeking care which were identified in this study. Mental health awareness raising activities should be provided in the community alongside the delivery of psychological interventions. This is to increase help-seeking and to tackle negative attitudes towards mental health and people with mental health problems.

Medical interventions following natural disasters: missing out on chronic medical needs.

Although natural disasters may cause massive loss of human life and destruction of resources, they also present affected populations with a rare opportunity to access external resources. Nevertheless, many post-disaster medical relief intervention programmes only focus on the provision of acute medical services and the control of communicable diseases. Currently, no specific study has examined why chronic medical needs seem to be insufficiently addressed in disaster relief interventions. This paper review current knowledge about how natural disasters affect people with chronic medical needs, assess possible factors in disaster preparedness and response that pre-empt addressing chronic medical needs and suggest possible ways to overcome these barriers. Unawareness and insensitivity of relief workers towards chronic medical conditions, the practice of risk rather than need-based assessments, a focus on acute needs, the lack of reliable indicators and baseline information, and the multidimensional characteristics of chronic medical problems all pose serious challenges and probably deter the government and post-disaster relief agencies to deal with diseases of a chronic nature. It is important to increase the awareness and sensitivity of the stakeholders towards chronic medical problems during all phases of planning and intervention. Relevant assessment tools should be developed to rapidly identify chronic medical needs in resource deficit settings. Community partnership and collaboration that promote local ownership and technical transfer of chronic disease management skills will be essential for the sustainability of services beyond the disaster relief period. Potential programmes might include the technical training of local staff, establishment of essential drug and supply lists, and the provision of a range of medical services that may address chronic health needs.

The epidemic of visceral leishmaniasis in western Upper Nile, southern Sudan: course and impact from 1984 to 1994.

BACKGROUND: Although endemic in parts of southern Sudan, visceral leishmaniasis (VL) had not been reported in Western Upper Nile (WUN) until an epidemic was confirmed in 1989. A combination of circumstances created conditions for transmission among a population of mainly Nuer and Dinka people who had no immunity. The civil war which restarted in 1983 has been a major contributing cause and continues to hinder provision of treatment, data collection and control measures. METHODS: Since the first of three clinics to treat VL was established in WUN in 1989, data on the epidemic and mortality have been collected in seven retrospective surveys of villages and among patients. Adults were interviewed about surviving family members and those who had died since the epidemic came. Survey death rates are used here to estimate mortality from VL and 'excess mortality' above expected levels. RESULTS: The surveys found high mortality at all ages and suggest an overall death rate of 38-57% since the epidemic started in 1984, and up to 70% in the most affected areas. Both methods of estimation suggest that around 100,000 deaths, among about 280,000 people in the epidemic area, might be attributable to VL. CONCLUSIONS: This continuing epidemic has shown that VL can cause high mortality in an outbreak with astonishingly high infection rates. Population movement has been a major factor in transmission and poor nutritional status has probably contributed to the risk of clinical infection. Although over 17,000 people have been successfully treated for VL at the clinics in WUN, the disease is likely to become endemic there.

PIP: The syndrome of fever, wasting, and enlarged spleen or lymph glands resulting from visceral leishmaniasis (VL) is usually fatal unless treated. While VL is endemic in parts of southern Sudan, it was first reported in Western Upper Nile (WUN) during a confirmed epidemic in 1989 among a population of mainly Nuer and Dinka people who had no immunity. Civil war has been a major contributing factor to the continuation and spread of the epidemic, and continues to impede the provision of treatment, data collection, and control measures. The first of three clinics to treat VL was established in WUN in 1989. Data have since been collected in seven retrospective surveys in villages and among patients. Survey death rates were used to estimate mortality from VL and excess mortality above expected levels. Mortality was high at all ages. The overall death rate is estimated at 38-57% since the epidemic started in 1984, and up to 70% in the most affected areas. Approximately 100,000 deaths, among approximately 280,000 people in the epidemic area, may be attributable to VL.

Visceral leishmaniasis in southern Sudan.

Reports made by Médecins Sans Frontières in Khartoum on an outbreak of visceral leishmaniasis among displaced people from the western Upper Nile prompted an investigation at Ler Hospital, the second largest in the region. In a 10 d period during April 1989, 100 persons with visceral leishmaniasis were identified. Of these, 82% were men; 67% were aged 20 to 39 years. Except for the absence of ulcerated skin lesions, the clinical features corresponded to those traditionally described in the Sudan. A cross-sectional serological survey was conducted in Kuernyang (400 inhabitants), 40 km north of Ler. The anti-Leishmania antibody prevalence was 18.2%, being higher among those older than 15 years, and higher among adult women (28%) than among men (18%). The overall prevalence of splenomegaly was 16.4%. 33% of seropositive cases presented with splenomegaly, compared with 11.6% of those who were seronegative. Three serological surveys conducted on the eastern side of the Nile showed no seropositive cases. However, 2 autochthonous cases were clinically diagnosed and confirmed by serological assays. The war conflicts and population movements appear to be the main cause of this large outbreak that may have killed thousands of tribespeople in southern Sudan. There is a risk of the disease spreading into other areas with devastating consequences for the population, should energetic measures not be immediately taken.

Pyrethroid-impregnated bed nets for personal protection against malaria for Afghan refugees.

A field trial of permethrin-impregnated bed nets (PIBs) was conducted in 2 Afghan refugee villages in Pakistan. Nets were issued to only 10% of families (= 1398 people); this simulated a situation in which bed nets are gradually adopted by villagers in Afghanistan. A further 10% lacking bed nets were selected as controls from the same villages. An initial survey showed that 86% of household heads were aware that malaria was transmitted by mosquito bites, but only 2% had used bed nets before. Trial families were encouraged to attend the village health centres if they fell ill. Microscopy records showed that, between July and December 1991, 22.4% of the control group became infected with Plasmodium vivax and 13.0% contracted P. falciparum while in the intervention group only 9.9% contracted P. vivax (relative risk 0.58, confidence interval [CI] 95% 0.49-0.68) and only 3.8% contracted P. falciparum (relative risk 0.39, 95% CI 0.29-0.53). A single treatment of the nets with permethrin at 0.5g/m2 remained protective throughout the 6 months' transmission season. 73% of families claimed to use their nets every night; members of families who claimed to use nets less regularly showed an incidence similar to that of the control group. There was no sex or age difference in net use or protective efficacy. Headlouse infestation rates were reduced in PIB users. Few nets were washed, given away or sold. The prospect for PIBs as personal protection appears good, despite people's lack of previous experience.

Kala-azar in displaced people from southern Sudan: epidemiological, clinical and therapeutic findings.

Six hundred and ninety-three patients with kala-azar were seen in Khartoum, Sudan, from January 1989 to February 1990. They were almost exclusively from the Nuer tribe, originating from the western Upper Nile province in southern Sudan, an area not known previously to be endemic for kala-azar. Because of the civil war in southern Sudan no treatment was available locally and massive migration to northern Sudan occurred; many died on the way. All age groups were affected; there was a slight male preponderance (56%). In the clinical presentation, marked generalized lymphadenopathy was prominent (84%). Splenomegaly was absent in 4% of cases. Patients usually showed anaemia, leucopenia and/or thrombocytopenia. 623 patients were treated with sodium stibogluconate, 10 mg/kg for 30 d; relapse occurred in 4% and death in 12%. Latterly, 70 patients were treated with sodium stibogluconate at 2 x 10 mg/kg for 15 d, with relapse in 6% and death in 6%. The difference between the 2 regimens in the number of relapses and deaths was not significant. The outbreak may have been caused by a combination of factors: the introduction of the parasite from an endemic area to a non-immune population, the presence of malnutrition caused by loss of cattle and unavailability of other food sources, and possibly an ecological change in favour of the sandfly vector.

Enhancing the quality of humanitarian assistance: taking stock and future initiatives.

During the last five years, the debate on the performance of humanitarian assistance has intensified. The motivation to "do better" has come both from within the humanitarian agencies as well as from pressure exerted by the donors and the media. Paradoxically, until now, the voice of those who are to benefit from this assistance has not been heard. This paper is an overview of the most important initiatives to increase the quality of humanitarian assistance. The introduction of the logical framework and the increasing body of knowledge made available through guidelines have improved project management by measuring process and outcomes. Increasingly, evaluations are used to give account and to learn from experiences. But, current evaluation practice must develop in a wider variety of approaches more appropriate to create change of the operations in the field. Some agencies oppose new developments like the Sphere and the Humanitarian Accountability Projects, arguing that standards and regulation would undermine necessary flexibility to adjust responses to the local context, or be a threat to their independence. Nonetheless, standards are considered to be a prerequisite as reference to assess performance. Furthermore, it is hoped that a new breakthrough will be achieved by improved accountability towards beneficiaries. An option to address some of the gaps in the current quality assessment tools was to widen the perspective on performance from projects to the organisations behind them. Quality management models may provide the required framework, and they also can be used to embed current initiatives by organisations. Humanitarian organisations may want to develop forms of self-regulation rather than waiting for accreditation by donors. Another area in which progress is needed is a system-wide approach to performance. At this level, the influence of political actors, donors, national governments, and other representatives of the parties in a conflict also should be assessed. It is their legal obligation to protect the basic right to assistance of persons affected by disasters, as enshrined in international law.

Factors associated with the health status of internally displaced persons in northern Uganda.

BACKGROUND: Globally, there are over 24 million internally displaced persons (IDPs) who have fled their homes due to violence and insecurity but who remain within their own country. There have been up to 2 million IDPs in northern Uganda alone. The objective of this study was to investigate factors associated with mental and physical health status of IDPs in northern Uganda. METHODS: A cross-sectional survey was conducted in November 2006 in IDP camps in the Gulu and Amuru districts of northern Uganda. The study outcome of physical and mental health was measured using the SF-8 instrument, which produces physical (PCS) and mental (MCS) component summary measures. Independent demographic, socio-economic, and trauma exposure (using the Harvard Trauma Questionnaire) variables were also measured. Multivariate regression linear regression analysis was conducted to investigate associations of the independent variables on the PCS and MCS outcomes. RESULTS: 1206 interviews were completed. The respective mean PCS and MCS scores were 42.2 (95% CI 41.32 to 43.10) and 39.3 (95% CI 38.42 to 40.13), well below the instrument norm of 50, indicating poor health. Variables with negative associations with physical or mental health included gender, age, marital status, income, distance of camp from home areas, food security, soap availability, and sense of safety in the camp. A number of individual trauma variables and the frequency of trauma exposure also had negative associations with physical and mental health. CONCLUSIONS: This study provides evidence on the impact on health of deprivation of basic goods and services, traumatic events, and fear and uncertainty amongst displaced and crisis affected populations.

Ethnic segregation in Kosovo's post-war health care system.

BACKGROUND: Seven years after the end of war in Kosovo, Final Status Negotiations have begun to determine the long-term political future of the province. This article provides an overview of the present situation regarding ethnic groups and their relations in Kosovo's health care system that might be helpful in preparing for the array of potential ramifications and repercussions that could arise at the conclusion of the negotiations. METHODS: A review of the literature (including grey) was performed, and 16 interviews and two focus groups with key informants were conducted in Kosovo during October and November 2004. In addition, six informal discussions were held in-person or by telephone in London. Information collected in 2004 was re-confirmed and partially updated in October and November 2005, when three additional interviews were conducted in Kosovo. RESULTS: Ongoing ethnic tensions in Kosovo, mainly between the Albanian and Serb populations, perpetuate a rigidly segregated health care system. Some other minority communities, such as the Roma, Ashkali and Egyptians, are afflicted by the double burden of getting caught up in the middle of these ethnic disputes and at the same time suffering from poverty and discrimination. CONCLUSION: While efforts have been put forward to promote peace-building within Kosovo's post-war health sector, very little progress has been achieved in fostering ethnic integration, reconciliation, cooperation or even co-existence. This failure reflects Kosovo's broader unresolved inter-ethnic problems. Final Status Negotiations are one of the last opportunities for the international community to address the problems of ethnic segregation in the province.

Cost-effectiveness analysis of humanitarian relief interventions: visceral leishmaniasis treatment in the Sudan.

Spending by aid agencies on emergencies has quadrupled over the last decade, to over US$6 billion. To date, cost-effectiveness has seldom been considered in the prioritization and evaluation of emergency interventions. The sheer volume of resources spent on humanitarian aid and the chronicity of many humanitarian interventions call for more attention to be paid to the issue of 'value for money'. In this paper we present data from a major humanitarian crisis, an epidemic of visceral leishmaniasis (VL) in war-torn Sudan. The special circumstances provided us, in retrospect, with unusually accurate data on excess mortality, costs of the intervention and its effects, thus allowing us to express cost-effectiveness as the cost per Disability Adjusted Life Year (DALY) averted. The cost-effectiveness ratio, of US$18.40 per DALY (uncertainty range between US$13.53 and US$27.63), places the treatment of VL in Sudan among health interventions considered 'very good value for money' (interventions of less than US$25 per DALY). We discuss the usefulness of this analysis to the internal management of the VL programme, the procurement of funds for the programme, and more generally, to priority setting in humanitarian relief interventions. We feel that in evaluations of emergency interventions attempts could be made more often to perform cost-effectiveness analyses, including the use of DALYs, provided that the outcomes of these analyses are seen in the broad context of the emergency situation and its consequences on the affected population. This paper provides a first contribution to what is hoped to become an international database of cost-effectiveness studies of health interventions during relief operations, which use a comparable measure of health outcome such as the DALY.

PIP: With spending by official aid agencies upon emergencies quadrupling over the past decade to more than US$6 billion, greater attention needs to be paid to the cost-effectiveness of the humanitarian interventions funded by such agencies. Data are presented from an epidemic of visceral leishmaniasis (VL) in civil war-torn Sudan, in a study of how such data could have been used in planning relevant health interventions. Data are available on the impact of a VL treatment program for 3067 patients between August 1990 and July 1991. Calculations made with the available data and relevant assumptions yielded a cost-effectiveness ratio of US$18.40 per Disability Adjusted Life Year (DALY), with an uncertainty range of US$13.53-27.63, a highly cost-effective health intervention. The applicability of the analysis to the internal management of the VL program, the procurement of funds for the program, and to priority setting in humanitarian relief interventions are discussed. When evaluating emergency interventions, efforts could be made more often to perform cost-effectiveness analyses, including the use of DALYs, provided that the outcomes of the analyses are seen in the broad context of the emergency situation and its consequences upon the affected population.

Resistance of falciparum malaria to chloroquine and sulfadoxine-pyrimethamine in Afghan refugee settlements in western Pakistan: surveys by the general health services using a simplified in vivo test.

Surveys of drug resistant falciparum malaria were conducted in several Afghan refugee settlements, distributed over a 700 km range in western Pakistan, during the transmission seasons of 1994 and 1995. Symptomatic malaria patients were recruited by a process of passive case detection at the refugees' basic health units. To facilitate follow-up by local health workers, a modified version of the WHO extended in vivo test was adopted in which blood smears were taken from each subject, and clinical symptoms recorded, at weekly intervals. Resistance to chloroquine and sulfadoxine-pyrimethamine was identified in every settlement. The frequency of chloroquine resistance ranged from 18% to 62%. Resistance occurred mostly as RI, with RII resistance never exceeding 11%. Resistance to sulfadoxine-pyrimethamine occurred at much lower frequencies, ranging from 4% to 25%. There was a resumption of clinical symptoms at the onset of parasite recrudescence in over 90% of cases. The policy of using chloroquine as first-line treatment might be changed in favour of sulfadoxine-pyrimethamine in most camps and areas of western Pakistan. The modified in vivo test was almost as accurate as the normal WHO in vivo test in identifying the grade of resistance, and should prove a useful tool for the monitoring of resistance to common antimalarials by district health services.

Sustainability of pyrethroid-impregnated bednets for malaria control in Afghan communities.

Between 1992 and 1995 a series of studies was undertaken to assess the long-term suitability of pyrethroid-impregnated bednets (PIBs) for malaria control in Afghan refugee communities in two villages in North-West Frontier Province, Pakistan. During 1992, 86% of bednet owners volunteered to have their bednets re-impregnated, and a further 15% of families purchased nets at two-thirds of cost price. From 1992 onwards, 27% of the villagers returned to Afghanistan, and annual house spraying campaigns were introduced to protect those still resident but sleeping without bednets. Within 3 years, these campaigns, together with PIBs, reduced the annual incidence of malaria by 87%, from 597 to 78 cases per 1000 population. Nevertheless, 65% of resident families continued to re-impregnate their nets annually with permethrin. To assess whether PIBs were still being used and were still protective, in view of these reduced transmission rates, we carried out a case--control study in 1994 on febrile or otherwise symptomatic patients presenting at village health centres. Comparison of the slide-positivity rates of PIB users and those without bednets showed that regular usage reduced the odds of contracting falciparum and vivax malaria to 0.22 (95% confidence interval (CI): 0.09-0.55) and 0.31 (95% CI: 0.19-0.51), respectively. There was no evidence of a sex- or age-bias in bednet use or in protective effect. The results indicate that a community-based PIB programme is an appropriate malaria control measure in areas where management or security problems make traditional house-spraying campaigns impossible. A relevant finding for those involved in the monitoring of bednet distribution projects is that the local coverage of bednets and the local impact on malaria, even when introduced to remote areas, can be estimated very cheaply by health centre microscopists who simply catalogue blood film diagnoses according to patients' bednet use practices.

A case-control study conducted in 1994 on febrile or otherwise symptomatic patients presenting at village health centers found that the regular use of bednets reduced the odds of contracting falciparum and vivax malaria to 0.22 and 0.31, respectively. No evidence was found of sex or age bias in bednet use or in protective effect.

Liposomal amphotericin B (AmBisome) in the treatment of complicated kala-azar under field conditions.

An open trial of liposomal amphotericin B (AmBisome [L-AmB]; Vestar, San Dimas, CA) for treatment of complicated visceral leishmaniasis was performed in Sudan. Forty-nine patients were treated, and there were six deaths (12% mortality); these were not attributed to therapy. Thirty-seven patients were selected for the trial because of (1) relapse after treatment with a combination of pentavalent antimony (Sbv) and aminosidine, (2) incomplete parasitological response to Sbv and aminosidine, or (3) severe illness. Drug regimen 1 (3 doses of 3-5 mg/kg, on days 0, 3, and 10) cured 8 (50%) of 16 patients; regimen 2 (6 doses of 3-5 mg/kg, on days 0, 3, 6, 8, 10, and 13) cured 14 (88%) of 16. For four of 10 partial responders, "rescue" therapy with L-AmB alone (3 mg/kg daily for 10 days) resulted in cure. Twelve less-unwell patients received regimen 3 (4 doses of 4-5 mg/kg, on days 0, 2, 5, and 7); seven of 11 patients evaluated (64%) were cured. The optimal regimen of L-AmB in these circumstances is administration of 4 mg/kg on days 0, 3, 6, 8, 10, and 13.

Leish-KIT, a stable direct agglutination test based on freeze-dried antigen for serodiagnosis of visceral leishmaniasis.

In order to increase the application potential of the direct agglutination test (DAT) for the detection of anti-Leishmania antibodies in human serum samples, we developed an antigen based on stained and freeze-dried Leishmania donovani promastigotes. We describe here the evaluation of the performance of the DAT based on this freeze-dried antigen. It was shown that the freeze-dried antigen remains fully active, even after storage at 56 degrees C for 18 months. With a cutoff value of 1:1,600, the sensitivity of the DAT was shown to be 92% and the specificity of the test was 99.7%, which were comparable with the results found for the DAT based on liquid antigen. The major advantages of the freeze-dried antigen are that the production of a large batch of this antigen allows reproducible results in the DAT over a long period of time and that the freeze-dried antigen can be stored at ambient temperature, which, as was shown, makes the test a valuable diagnostic tool for use in the field.
