BackgroundData on the incidence and burden of Clostridium difficile infection (CDI) in Asia is limited.ObjectivesTo evaluate the incidence and burden of CDI in Thailand.MethodsWe used 2010 Nationwide Hospital Admission Data, which included the diagnosis of digestive disorders from various causes coded using the ICD-10. Patients with a diagnosis of Clostridium difficile (ICD10-A07) aged >18 years, were included. Their baseline characteristics, clinical outcomes, and risk factors for CDI were analyzed. Length of hospital stay (LOS), mortality rate, and hospital expenses were used as indicators to evaluate the burden of CDI in Thailand.ResultsOf 4,863,935 admissions in 2010, 554 patients in 570 admissions (0.01%) were diagnosed with CDI. Of these, 106 (19.1%) died during the index hospitalization, and 98.1% had at least one comorbidity. The mean LOS for patients with CDI was longer than with other colitis (P < 0.001) and was also significantly longer for those who died during the index admission, compared with those who survived during the index admission (P = 0.04). The hospital expense for those who died was significantly higher than for those who survived (P < 0.001). From a multivariate analysis, age ≥85 years old, comorbidity, and sepsis were risk factors for mortality during admission with adjusted odds ratios of 2.40, 7.4, and 5.14, respectively.ConclusionsThe calculated burden of CDI in Thais is high; although the incidence of CDI is lower in Thailand than in Western countries. The mortality relates to the elderly age-group and comorbidity, especially sepsis.


<div xmlns="http://www.w3.org/1999/xhtml"><p><italic>Clostridium difficile</italic> infection (CDI) is a well-known leading cause of hospital associated gastrointestinal disease [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_001_w2aab3b7b7b1b6b1ab1b8b1Aa">1</a>].

CDI is included among diseases with a high burden affecting people in Western countries. The annual cost of hospital care for patients was 3.2 billion dollars in the U.S. health-care system [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_008_w2aab3b7b7b1b6b1ab1b8b8Aa">8</a>, <a ref-type="bibr" href="#j_1905-7415.0906.451_ref_009_w2aab3b7b7b1b6b1ab1b8b9Aa">9</a>].

However, the previous data are inhomogeneous and do not represent the overall incidence and burden of CDI in Southeast Asia including Thailand. To address this, we sought to evaluate the incidence, burden, and risk factors for CDI in Thailand by using the nationwide database from 2010. Findings from this study will help to explore the importance of CDI in Thailand, representing Southeast Asia, and help to plan future health policies.</p><sec id="j_1905-7415.0906.451_s_006_w2aab3b7b7b1b6b1ab1b2Aa"><div>Methods</div><p>We retrieved in-patient medical data, including the expense of hospitalization, from the 2010 Thailand Nationwide Hospital Admission Database available from the National Health Security Office.

From 2004-2008, Korea reported a nationwide incidence of CDI infection in adults at approximately 0.2% among overall admissions [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_018_w2aab3b7b7b1b6b1ab1b8c18Aa">18</a>]. Although not covering the same period, the Korean incidence of CDI was higher than that reported for Thailand. From the present study, the incidence of CDI in Thailand in 2010 was estimated at only 0.01%. By contrast, the U.S. Center for Disease Control and Prevention surveyed across 10 U. S. geographical regions in 2011 and calculated that the estimated CDI prevalence was 0.14% (95%CI; 0.12%-0.16%) among overall population [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_019_w2aab3b7b7b1b6b1ab1b8c19Aa">19</a>]. Both studies in Asia (Korea and Thailand) retrieved the data from overall admissions (incidence), whereas the U.S. study calculated the results from the population overall (prevalence). Although the prevalence of CDI in the U.S. cannot be compared with the incidence in Korea and Thailand directly, it can be assumed that the incidence in the U.S. should be much higher than in either Asian country [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_018_w2aab3b7b7b1b6b1ab1b8c18Aa">18</a>, <a ref-type="bibr" href="#j_1905-7415.0906.451_ref_019_w2aab3b7b7b1b6b1ab1b8c19Aa">19</a>]. In 2014, an analysis of the U.S. Nationwide Inpatient Sample Healthcare Cost and Utilization Project database reported the epidemiology of CDI in patients after cardiac surgery, which had low risk of CDI, at 0.75% over 5 years [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_020_w2aab3b7b7b1b6b1ab1b8c20Aa">20</a>].

Diet is known as an important factor causing modification of gut microbiota, and a normal flora may be associated with CDI [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_021_w2aab3b7b7b1b6b1ab1b8c21Aa">21</a>]. Consequently, Asian populations may have different microbiota than populations in Western countries and this may account for the lower rate of CDI in Thai and Korean people. A study in China [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_022_w2aab3b7b7b1b6b1ab1b8c22Aa">22</a>] found that Chinese <italic>Fen-Daqu</italic> (a starter for liquor and vinegar fermentation) can alter the microbial species of its environment. In Chinese food, these microbial environments may not be compatible with the <italic>C. difficile</italic>, thus reducing the degree of <italic>C. difficile</italic> proliferation and contamination. Moreover, over production of <italic>Bacillus</italic> species may inhibit the growth rate of <italic>C. difficile</italic>. However, there has been no nationwide CDI study conducted in China to support these hypotheses. In the present study, one might presume that Southeast Asian food may offer protective factors against CDI; preserving healthy microbiota that can combat the <italic>C. difficile</italic> organism and reduce the CDI rate. Prospective studies need to be conducted to prove this hypothesis. Furthermore, Thais do not often take antibiotics, and even less so in rural areas, despite the availability of these medications as over-the-counter drugs. Traditions of rural people may help to protect them against CDI, despite other risk factors.</p><p>This study emphasized that old age is an important factor for CDI infection and can predict mortality because of CDI. Although much of the CDI occurred in young to middle-age patients (i.e., &lt;65 years old), the proportion varied within each age group. The highest incidence for CDI was found in the group ≥85 years-old, whereas the proportions in the 18-44, 45-64, and 65-84 year-old age groups were progressively less with age <bold>(<a ref-type="fig" href="#j_1905-7415.0906.451_fig_001_w2aab3b7b7b1b6b1ab1b3b3aAa">Figure 1</a>)</bold>. These results were consistent with the findings of an epidemiological study in the U.S. [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_004_w2aab3b7b7b1b6b1ab1b8b4Aa">4</a>].</p><p>Comorbidity is an important parameter in the mortality rate of CDI patients. Approximately 90% of CDI patients had comorbidity, and almost all of the patients who died during index admission had comorbidity (98.1%). Comorbidity has been suggested as the precipitating factor of CDI, but the evidence has not been clear [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_007_w2aab3b7b7b1b6b1ab1b8b7Aa">7</a>]. Here we show that comorbidity is an important mortality risk factor with an OR of 7.47 in multivariate analysis. In this study, the most important comorbidity associated with mortality was sepsis. Sepsis is a risk factor that predicts CDI because patients always require antibiotic treatment, which is a well-known risk factor for CDI [<a ref-type="bibr" href="#j_1905-7415.0906.451_ref_007_w2aab3b7b7b1b6b1ab1b8b7Aa">7</a>, <a ref-type="bibr" href="#j_1905-7415.0906.451_ref_023_w2aab3b7b7b1b6b1ab1b8c23Aa">23</a>]. LOS was not a predictor of death, because severe CDI was life-threatening, and these patients typically died within a few days after diagnosis.</p><p>Our retrospectively data collection is the main limitation of the present study. The authors obtained all information from summary discharge; therefore, the information was limited. This study could not retrieve the result of investigation, criteria for CDI diagnosis, history of antibiotic usage, history of previous admission from other causes, nor other possible associated risk factors, such as proton pump inhibitor prescription. Moreover, this study relied on ICD 10 coding for CDI diagnosis, which may be inaccurate. Nevertheless, this is the first large scale study in Thailand that can represent the actual situation and can thus guide future health policy decisions.</p></sec><sec id="j_1905-7415.0906.451_s_009_w2aab3b7b7b1b6b1ab1b5Aa"><div>Conclusion</div><p>From a first nationwide study in Thailand, the burden of CDI infection in Thailand is high, even though the prevalence of CDI is likely to be relatively low.
