Objective. The year 2010 is the first time that the Rhode Island hospital discharge database included present on admission (POA) indicators, which give us the opportunity to distinguish cases of hospital-onset Clostridium difficile infection (CDI) from cases of community-onset CDI and to assess the burden of hospital-onset CDI in patients discharged from Rhode Island hospitals during 2010 and 2011. Design. Observational study. Patients. Patients 18 years of age or older discharged from one of Rhode Island's 11 acute-care hospitals between January 1, 2010, and December 31, 2011. Methods. Using the newly available POA indicators in the Rhode Island 2010 and 2011 hospital discharge database, we identified patients with hospital-onset CDI and without CDI. Adjusting for patient demographic and clinical characteristics using propensity score matching, we measured between-group differences in mortality, length of stay, and cost for patients with hospital-onset CDI and without CDI. Results. In 2010 and 2011, the 11 acute-care hospitals in Rhode Island had 225,999 discharges. Of 4,531 discharged patients with CDI (2.0% of all discharges), 1,211 (26.7%) had hospital-onset CDI. After adjusting for patient demographic and clinical characteristics, discharged patients with hospital-onset CDI were found to have higher mortality rates, longer lengths of stay, and higher costs than those without CDI. Conclusions. Our results highlight the burden of hospital-onset CDI in Rhode Island. These findings emphasize the need to track longitudinal trends to tailor and target population-health and quality-improvement initiatives.

ABSTRACT: With Clostridium difficile infection (CDI) on the rise, knowledge of the current economic burden of CDI can inform decisions on interventions related to CDI. We systematically reviewed CDI cost-of-illness (COI) studies. We performed literature searches in six databases: MEDLINE, Embase, the Health Technology Assessment Database, the National Health Service Economic Evaluation Database, the Cost-Effectiveness Analysis Registry, and EconLit. We also searched gray literature and conducted reference list searches. Two reviewers screened articles independently. One reviewer abstracted data and assessed quality using a modified guideline for economic evaluations. The second reviewer validated the abstraction and assessment. We identified 45 COI studies between 1988 and June 2014. Most (84%) of the studies were from the United States, calculating costs of hospital stays (87%), and focusing on direct costs (100%). Attributable mean CDI costs ranged from $8,911 to $30,049 for hospitalized patients. Few studies stated resource quantification methods (0%), an epidemiological approach (0%), or a justified study perspective (16%) in their cost analyses. In addition, few studies conducted sensitivity analyses (7%). Forty-five COI studies quantified and confirmed the economic impact of CDI. Costing methods across studies were heterogeneous. Future studies should follow standard COI methodology, expand study perspectives (e.g., patient), and explore populations least studied (e.g., community-acquired CDI).Am J Gastroenterol advance online publication, 7 April 2015; doi:10.1038/ajg.2015.48.The 36th Annual Meeting of the Society for Medical Decision Making; 10/2014

ABSTRACT: Objective: To evaluate the prevalence of C. difficile infection (CDI) among hospitalized patients with toxin-positive stools. Methods: This study is a multicenter study held in Jordan and focused on the prevalence of in-patients with C. difficile toxin-positive diarrhea-stools. The study included three hospitals with approximately 750 beds. In-patients charts, laboratory logbooks for in-patients with diarrhea-stool specimens were reviewed. The participating hospitals used a rapid test, which detects fecal C. difficile toxins A and B. Results: 174 stool specimens were reviewed from March 2013 to October 2014, and 170 stool specimens from 168 patients were evaluated. The patients included 102 (60%) males, and 66 (40%) females including seven (10.6%) peripartum females. The patients were classified in the following age groups:neonates ≤ 28 days, infants 29 days - less than one year old (n = 4, 2.4%), 1 – 4 years (n = 3, 1.8%), and arbitrarily: 5 - 9 years (n = 3, 1.8%), 10 – 14 years (n = 3, 1.8%), 15 – 40 years (n = 33, 19.4%), 41- 64 years, (n = 53, 31.2%) and ≥ 65 years were (n = 71, 41.8%).Adults and older age groups make up the majority of all patients (92.4%). Comorbidities were highly prevalent among the patients: diabetic (n = 71, 41.8%), chronic lung diseases (n = 25, 14.7%), solid tumors other than colonic tumors (n = 12, 7.1%), immune-suppressive state (n = 15, 8.8%), and one patient had colonic tumor. The majority of the patients (n = 21) were on more than one class of broad-spectrum antimicrobials. The prevalence of C. difficile toxin-positive stools were 14.63/1000 discharged patients, 12.65% of patients (12.96% of stool specimens) and 5.0/1000 patient-day. The age-adjusted CDI distribution showed that the rates increased with age and were relatively low in the neonatal period. Conclusion: The hospital-associated C. difficile prevalence showed high rates, particularly in adults and older patients, in patients with a prolonged hospital stay, and comorbidities.
