In the affected countries, the respective governments and local and Tinternational non-governmental organizations have initiated numerous programs for the reconstruction and rehabilitation of the affected areas. Recovery activities remain ongoing and several are still being planned. Tsunami-affected Villages : Thailand Figure 1.

Monitoring oF Key health indicators (triaMs) at subdistrict health Facilities in tsunaMi-aFFected provinces in thailand Of major interest now is an evaluation of the recovery process in the affected areas. The Tsunami Recovery Impact Assessment and Monitoring Systems (TRIAMS) have been set up to initiate processes and strengthen regional and national mechanisms to facilitate planning for further recovery activities; hence, numerous core and country-specific impact assessment and monitoring indicators have been formulated under 4 major headings: ) vital needs, 2) basic social services, 3) infrastructure, and 4) livelihoods. But, in order to succeed in monitoring such indicators, the existence of a detailed and reliable database is critical. This need prompted the conduct of this survey. The contents of this report are based on a survey of health-related TRIAMS indicators carried out November 2006-January 2007 in the 6 tsunami-affected areas in southern Thailand (Fig ). SPECIFIC OBJECTIVES . To measure the impact of the tsunami on health, using key indicators derived from the TRIAMS. 2. To generate a baseline database of health-related indicators in the tsunami-affected villages. MATERIALS AND METHODS Study area and data collection he areas selected for this survey were confined to the tsunami-affected provinces of Phangnga, Krabi, Phuket, Ranong, Trang, and Satun, wherein 408 of the total ,946 Tvillages were affected. The proportions of the affected districts and subdistricts are listed in Table , below. Plates & 2 show the district and subdistrict boundaries of the tsunami- affected areas. Table 1.

As annexed in the TRIAMS workshop report2, data for country indicators vary in terms of their geographic scale (i.e. subdistrict or district levels). To address this, subdistrict data were collected from health centers, while district data were taken from each district’s respective health office and community hospital. Table 2 shows the list of identified indicators and their respective sources. Table 2.

Monitoring oF Key health indicators (triaMs) at subdistrict health Facilities in tsunaMi-aFFected provinces in thailand Data management and analysis he data collected were organized and processed using Microsoft® Access and Microsoft® Excel. Maps were created with ArcView® 3.3 using the ESRI shapefile Tspecification (*.shp). Spatial analysis was performed using GeoDa™ 0.95i. The results are presented through thematic maps and summary statistics. Spatial analyses of the various indicators were conducted, including identification of local clusters using Moran’s I for spatial autocorrelation at the subdistrict level. The analysis considers the attribute values of each subdistrict and compares it with the same attribute values of other adjacent areas considered as “neighbors”. A “neighbor” in this case is an affected subdistrict that shares a common border with one or more other affected subdistricts. This manner of identifying neighbors is called the rook contiguity. Evaluation of how each subdistrict is related to each other in terms of location and contiguity gives rise to numeric spatial weights essential for calculating the relevant statistics. The presence of global or overall clustering is given by Moran’s I with p-values calculated based on conditional permutation as implemented in GeoDa. The level of significance was set at 0.05 with 999 permutations. Moreover, significant local clustering was assessed using local Moran statistics calculated through randomization (using 999 permutations). Subdistricts were then classified into 5 cluster categories: not statistically significant, HIGH-HIGH, LOW-LOW, HIGH-LOW, and LOW-HIGH. In the analysis, a subdistrict with a high attribute value contiguous to one or more neighboring areas with similarly high values were classified as HIGH-HIGH clusters. Conversely, areas with low values in proximity to neighboring areas with similarly low values were classified as LOW-LOW clusters. HIGH-LOW clusters are areas with high values surrounded by areas with low values, while LOW-HIGH clusters are areas with low values surrounded by areas with high values. HIGH-LOW and LOW-HIGH clusters are also known as spatial outliers, since the neighboring values do not agree with the local values. HIGH-HIGH and LOW-LOW locations indicate positive local spatial autocorrelation (spatial clusters) while HIGH-LOW and LOW-HIGH locations indicate negative local spatial autocorrelation (spatial outliers)4. While spatial clusters may highlight areas where recovery activities need to be strengthened, spatial outliers may also provide insights where the levels of the specific indicators are not distributed homogeneously.

Crude death rates in the tsunami-affected Idistricts ranged from .8 per ,000 population in Nua Khlong, Krabi to 7 per ,000 in Muang Ranong, Ranong. On average, the crude death rate in the affected district was 4.63 ± 2.95 per ,000 (Table 3).
