Traffic Inj Prev 2019 20 (4) 1-7 OBJECTIVES: The objective of this study was to evaluate and injury surveillance (IS) system's ability to monitor road traffic deaths and the coverage of road traffic injury and death surveillance in Phuket, Thailand. METHODS: U.S. Centers for Disease Control and Prevention guidelines on surveillance system evaluation were used to qualitatively and quantitatively evaluate IS. Interviews with key stakeholders focused on IS's usefulness, simplicity, flexibility, acceptability, and stability. Active case finding of 2014 road traffic deaths in all paper and electronic hospital record systems was used to assess system sensitivity, positive predictive value, and data quality. Electronic data matching software was used to determine the implications of combining IS data with other provincial-level data sources (e.g., death certificates, electronic vehicle insurance claim system). RESULTS: Evaluation results indicated that IS was useful, flexible, acceptable, and stable, with a high positive predictive value (99%). Simplicity was limited due to the burden of collecting data on all injuries and use of paper-based data collection forms. Sensitivity was low, with IS only identifying 55% of hospital road traffic death cases identified during active case finding; however, IS cases were representative of cases identified. Data accuracy and completeness varied across data fields. Combining IS with active case finding, death certificates, and the electronic vehicle insurance claim system more than doubled the number of road traffic death cases identified in Phuket. CONCLUSION: An efficient and comprehensive road traffic injury and death surveillance system is critical for monitoring Phuket's road traffic burden. The hospital-based IS system is a useful system for monitoring road traffic deaths and assessing risk behaviors. However, the complexity of data collection and limited coverage hinders the ability of IS to fully represent road traffic deaths in Phuket Province. Combining data sources could improve coverage and should be considered. |
Estimation of the incidence of hepatocellular carcinoma and cholangiocarcinoma in Songkhla, Thailand, 1989-2013, using multiple imputation method
Yeesoonsang S , Bilheem S , McNeil E , Iamsirithaworn S , Jiraphongsa C , Sriplung H . Cancer Res Treat 2017 49 (1) 54-60 PURPOSE: Histological specimens are not required for diagnosis of liver and bile duct (LBD) cancer, resulting in a high percentage of unknown histologies. We compared estimates of hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) incidences by imputing these unknown histologies. MATERIALS AND METHODS: A retrospective study was conducted using data from the Songkhla Cancer Registry, southern Thailand, from 1989 to 2013. Multivariate imputation by chained equations (mice) was used in re-classification of the unknown histologies. Age-standardized rates (ASR) of HCC and CCA by sex were calculated and the trends were compared. RESULTS: Of 2,387 LBD cases, 61% had unknown histology. After imputation, the ASR of HCC in males during 1989 to 2007 increased from 4 to 10 per 100,000 and then decreased after 2007. The ASR of CCA increased from 2 to 5.5 per 100,000, and the ASR of HCC in females decreased from 1.5 in 2009 to 1.3 in 2013 and that of CCA increased from less than 1 to 1.9 per 100,000 by 2013. RESULTS: of complete case analysis showed somewhat similar, although less dramatic, trends. CONCLUSION: In Songkhla, the incidence of CCA appears to be stable after increasing for 20 years whereas the incidence of HCC is now declining. The decline in incidence of HCC among males since 2007 is probably due to implementation of the hepatitis B virus vaccine in the 1990s. The rise in incidence of CCA is a concern and highlights the need for case control studies to elucidate the risk factors. |
A population-based acute meningitis and encephalitis syndromes surveillance in Guangxi, China, May 2007- June 2012

PLoS One 2015 10 (12) e0144366 OBJECTIVES: Acute meningitis and encephalitis (AME) are common diseases with the main pathogens being viruses and bacteria. As specific treatments are different, it is important to develop clinical prediction rules to distinguish aseptic from bacterial or fungal infection. In this study we evaluated the incidence rates, seasonal variety and the main etiologic agents of AME, and identified factors that could be used to predict the etiologic agents. METHODS: A population-based AME syndrome surveillance system was set up in Guigang City, Guangxi, involving 12 hospitals serving the study communities. All patients meeting the case definition were investigated. Blood and/or cerebrospinal fluid were tested for bacterial pathogens using culture or RT-PCR and serological tests for viruses using enzyme-linked immunosorbent assays. Laboratory testing variables were grouped using factor analysis. Multinomial logistic regression was used to predict the etiology of AME. RESULTS: From May 2007 to June 2012, the annual incidence rate of AME syndrome, and disease specifically caused by Japanese encephalitis (JE), other viruses, bacteria and fungi were 12.55, 0.58, 4.57, 0.45 and 0.14 per 100,000 population, respectively. The top three identified viral etiologic agents were enterovirus, mumps virus, and JE virus, and for bacteria/fungi were Streptococcus sp., Cryptococcus neoformans and Staphylococcus sp. The incidence of JE and other viruses affected younger populations and peaked from April to August. Alteration of consciousness and leukocytosis were more likely to be caused by JE, bacteria and fungi whereas CSF inflammation was associated with bacterial/fungal infection. CONCLUSIONS: With limited predictive validity of symptoms and signs and routine laboratory tests, specific tests for JE virus, mumps virus and enteroviruses are required to evaluate the immunization impact and plan for further intervention. CSF bacterial culture cannot be omitted in guiding clinical decisions regarding patient treatment. |
Injuries and deaths at a pub fire in Bangkok, Thailand on New Year's Eve 2009
Jongcherdchootrakul K , Henderson AK , Jiraphongsa C . Burns 2011 37 (3) 499-502 This investigation describes the 67 people who died and the 153 who were hospitalized from a New Years' Eve fire in a Bangkok pub. We interviewed survivors and reviewed medical charts and forensic reports of decedents. Survivors were young (median age 27 years), single (84.7%) and lived in Thailand (93.6%). Most were on the concert floor when the fire started (74.0%), became aware of danger when they saw flames (61.5%) and escaped through the main entry door (42.9%). Common injuries were burns (75.6%), smoke inhalation (47.4%) and open wounds (32.1%). The decedents' median age was 27 years and 88.1% lived in Thailand. Most of the dead bodies were found at or near the main entrance. The main causes of death were asphyxia (88.1%) or burn (10.4%). Soot was present in the trachea of 95.5% of the decedents. Carboxyhemoglobin level in 37.5% was in the toxic range. The average percent of body surface burned was 75.0%. Loss of consciousness in the pub (RR 3.5, 95% CI 1.7-7.3) was a risk factor for severe injury and smoke inhalation (RR 9.3, 95% CI 3.1-28.0) was a risk factor for death. |
