Growing pains of East Timor: health of an infant nation

Opportunities to improve vaccination coverage in a country with a fledgling health system: Findings from an assessment of missed opportunities for vaccination among health center attendees-Timor Leste, 2016

INTRODUCTION

Since its independence in 2002, Timor Leste has made significant strides in improving childhood vaccination coverage. However, coverage is still below national targets, and children continue to have missed opportunities for vaccination (MOV), when eligible children have contact with the health system but are not vaccinated. Timor Leste implemented the updated World Health Organization methodology for assessing MOV in 2016.

METHODS

The MOV data collection included quantitative (caregiver exit interviews and health worker knowledge, attitudes, practices surveys (KAP)) and qualitative arms (focus group discussions (FGDs) with caregivers and health workers and in-depth interviews (IDIs) with health administrators). During a four-day period, health workers and caregivers with children <24 months of age attending the selected eight facilities in Dili Municipality were invited to participate. The researchers calculated the proportion of MOV and timeliness of vaccine doses among children with documented vaccination histories (i.e., from a home-based record or facility register) and thematically analyzed the qualitative data.

RESULTS

Researchers conducted 365 caregiver exit interviews, 169 health worker KAP surveys, 4 FGDs with caregivers, 2 FGDs with health workers, and 2 IDIs with health administrators. Among eligible children with documented vaccination histories (n = 199), 41% missed an opportunity for vaccination. One-third of health workers (33%) believed their knowledge of immunization practices to be insufficient. Qualitative results showed vaccines were not available at all selected health facilities, and some facilities reported problems with their cold chain equipment.

CONCLUSION

This study demonstrates that many children in Timor Leste miss opportunities for vaccination during health service encounters. Potential interventions to reduce MOV include training of health workers, improving availability of vaccines at more health facilities, and replacing unusable cold chain equipment. Timor Leste should continue to scale up successful MOV interventions beyond Dili Municipality to improve vaccination coverage nationally and strengthen the health system overall.

Public Health and Health Services Development in Postconflict Communities: A Case Study of a Safe Motherhood Project in East Timor

Armed conflict causes suffering in many countries; it contributes to poor health and hinders health services development. The effects of conflict are evidenced by weakened community structures and can make reconstruction efforts challenging. East Timor has a history of prolonged conflict and saw a resurgence of internal violence in 2006. This participant observation study discusses considerations for implementing public health and health systems development projects in postconflict settings using a case study of a maternal and child health project. It illustrates the importance of appreciating the historical context and community dynamics when implementing development projects. The sequelae of conflict are often characterized by reduced human resource development capacity, distrust of hierarchy, and limited capacity for resource mobilization. Working in such postconflict communities requires flexibility in program design, stronger efforts for community capacity building, and rebuilding trust between various stakeholders.

Explosive anger as a response to human rights violations in post-conflict Timor-Leste

Over several decades, clinicians have documented a pattern of explosive anger amongst survivors of gross human rights violations. Yet there is a dearth of epidemiological research investigating explosive anger in post-conflict countries. In the present study undertaken in Timor-Leste between March and November 2004, we identified an indigenous descriptor for explosive anger, including this index in the East Timor Mental Health Epidemiological Needs Study, a small area total population survey of 1544 adults living in an urban and a rural area. Other measures included indices of past trauma events, post-traumatic stress and general psychological distress, and socio-demographic variables. We found that 38% of the population reached the defined threshold of one attack of explosive anger a month (average=1 episode every 2-3 days). Only a minority of persons with explosive anger reached threshold scores for post-traumatic stress and general psychological distress. High levels of trauma exposure represented the strongest predictor of explosive anger. Latent class analysis identified three sub-groups with explosive anger: young trauma-affected adults living in the capital city who were unemployed; an older group, predominantly men, who had experienced extensive violence, including combat, assault and torture; and a less well characterized group of women. The findings offer support for a sequential model of explosive anger in which experiences of past persecution are compounded by frustrations in the post-conflict environment. The data provide a foundation for exploring further the role of trauma-induced anger in the cycles of violence that are prevalent in post-conflict countries.

Analysis of genetic mutations associated with anti-malarial drug resistance in Plasmodium falciparum from the Democratic Republic of East Timor

BACKGROUND

In response to chloroquine (CQ) resistance, the policy for the first-line treatment of uncomplicated malaria in the Democratic Republic of East Timor (DRET) was changed in early 2000. The combination of sulphadoxine-pyrimethamine (SP) was then introduced for the treatment of uncomplicated falciparum malaria.

METHODS

Blood samples were collected in two different periods (2003-2004 and 2004-2005) from individuals attending hospitals or clinics in six districts of the DRET and checked for Plasmodium falciparum infection. 112 PCR-positive samples were inspected for genetic polymorphisms in the pfcrt, pfmdr1, pfdhfr and pfdhps genes. Different alleles were interrogated for potential associations that could be indicative of non-random linkage.

RESULTS

Overall prevalence of mutations associated with resistance to CQ and SP was extremely high. The mutant form of Pfcrt (76T) was found to be fixed even after five years of alleged CQ removal. There was a significant increase in the prevalence of the pfdhps 437G mutation (X2 = 31.1; p = 0.001) from the first to second survey periods. A non-random association was observed between pfdhfr51/pfdhps437 (p = 0.001) and pfdhfr 59/pfdhps 437 (p = 0.013) alleles.

CONCLUSION

Persistence of CQ-resistant mutants even after supposed drug withdrawal suggests one or all of the following: local P. falciparum may still be inadvertently exposed to the drug, that mutant parasites are being "imported" into the country, and/or reduced genetic diversity and low parasite transmission help maintain mutant haplotypes. The association between pfdhfr51/pfdhps437 and pfdhfr 59/pfdhps 437 alleles indicates that these are undergoing concomitant positive selection in the DRET.

Survey of childhood malnutrition at Dili National Hospital, East Timor

OBJECTIVES

To describe the characteristics and short-term outcomes of children with malnutrition admitted to Dili National Hospital (DNH), East Timor.

METHODS

A prospective observational survey using caretaker interviews and medical record review was conducted on the paediatric ward at DNH for 12 months from March 2002. Patients were children aged 2 months to 12 years, admitted with moderate to severe malnutrition as either a primary or secondary diagnosis.

RESULTS

Malnutrition was present in 31.8% (280/880) of paediatric admissions during the study period. Sixty-one per cent of the malnutrition cases were severe malnutrition (weight-for-height below -3 Z-scores and/or oedema) and 53.7% were both wasted and stunted. The hospital case-fatality rate was 12.9% (36/280). Immunization coverage was low, with 39% of cases never immunized and 29% incompletely immunized according to the national immunization schedule.

CONCLUSIONS

There is a high rate of malnutrition among paediatric inpatients at DNH, consistent with results of anthropometric surveys in the newly independent East Timor. Despite the introduction of a standardized protocol following WHO guidelines and associated training on the management of severe malnutrition, the hospital case-fatality rate for severe malnutrition was still high (12.9%).

Australian Defence Force surgical support to peacekeeping operations in East Timor

BACKGROUND

The Australian Defence Force (ADF) has provided surgical support to peacekeeping operations in East Timor since September 1999. The aim of the present paper is to document the wide range of surgical procedures performed by the ADF in East Timor from September 1999 to December 2002 on peacekeeping force personnel and the civilian population.

METHODS

Records of all surgical procedures performed by the ADF in East Timor from their arrival in September 1999 to December 2002 were retrospectively reviewed. Details of the type of procedures performed and anaesthetic administered, the age and sex of the patients and whether they were a member of peacekeeping forces or East Timorese civilian were recorded.

RESULTS

There were 702 surgical procedures performed by the ADF in East Timor during this period, of which 401 (57%) were for peacekeeping force personnel and 301 (43%) were for East Timorese or other civilians. The most commonly performed procedures were for the management of non-battle wounds, accounting for 181 cases (26%). Battle-type wounds accounted for only 36 procedures (5%). Obstetric and gynaecology cases accounted for 30 procedures (4%). Fifty-six procedures (8%) were on children 12 years or younger.

CONCLUSIONS

The wide range of surgical procedures performed by the ADF during peacekeeping operations in East Timor highlights the requirement for deployed surgeons to possess a broad range of clinical skills and has implications for their preparation and training. Battle-type wounds accounted for only a small proportion of procedures.

Pathology in East Timor

East Timor is the newest nation in Southeast Asia and, with its recent turbulent history, also one of the poorest. Infectious and parasitic diseases such as tuberculosis and malaria are endemic, and the poor infrastructure in the wake of Indonesia's sudden withdrawal has left the country with enormous health challenges. Australia's key role in the emergence of East Timor as an independent country brings with it a long-term interest in the future development of its health services, including pathology.
