How much stool can be transferred from a plastic diaper to a sterile container?

For patients requiring the use of diapers, first line the diaper with clean plastic to prevent absorption. Then transfer 5 grams or 5 mL of the stool specimen from the plastic lined diaper to the sterile container. Do not submit the diaper itself. Cap securely.

What is the ICD-10 code for C. difficile?

All patients with a positive laboratory result for C. difficile (Bact+) and/or the ICD-10 discharge code for C. difficile infection, A04.7, as principal or associated diagnosis (ICD10+), were identified. For patients with multiple laboratory results during the same hospitalization, we used only the initial result.

What is the sensitivity of Clostridium difficile?

The sensitivity and specificity of surveillance for Clostridium difficile infections according to International Classification of Diseases, 10th revision, codes were compared with laboratory results as standard. Sensitivity was 35.6%; specificity was 99.9%. Concordance between the 2 methods was moderate. Surveillance based on ICD-10 codes underestimated the rate based on laboratory results.

How long is the ICD-10 study?

This study covers an 11-year period and provides a large study population and more comprehensive analysis of the performance of ICD-10 codes. Our results indicate that surveillance for C. difficile infections based on ICD-10 codes underestimates the rate of C. difficile infections based on microbiological findings at Saint-Antoine Hospital. Even though trends in C. difficile infections incidence for the 2 methods correlated strongly, concordance was moderate.

How sensitive is the ICD-10 code?

The sensitivity of ICD-10 codes in this study is inferior to values previously reported in the United States (71%–78%) and in Singapore (49.6%) ( 8–11 ). Poor sensitivity and variability among wards could be attributed to differences in awareness by health care professionals of C. difficile infections and to differences in coding practices. At Saint-Antoine Hospital, coding is performed by physicians with limited training, not by trained medical coders. Therefore, the quality of coding can vary from 1 physician to another and among wards. In addition,, differences in sensitivity could be explained by changes in hospital financing. As of 2006, funding for hospitals in France has been connected to coding through Activity Based Payment ( 13 ). Comparison of average sensitivity before and after 2006 showed an overall increase, indicating that coding practices might improve with time as hospitals adapt to this system.

Is the ICd 10 code sensitivity variable?

The sensitivity of ICD-10 codes can be highly variable, and this method should be validated in different health care settings before being used for surveillance.

What is the ICD-10 code for C difficile?

The ICD-10 system does include a code for CDAD (A04.7, Enterocolitis due to C. difficile ), so the ICD-based system presented here could be modified to be used with the updated coding system.

What is the sensitivity of the ICD-9 code for Clostridium difficile?

The correlation between toxin assay results and ICD-9 codes was good (κ = 0.72, p<0.01). The sensitivity of the ICD-9 codes was 78% and the specificity was 99.7%.

How long does it take to get a stool sample from a positive toxin?

The first positive stool sample was collected within 48 hours of discharge for 68 (44%) of admissions with a positive toxin assay only (CDTA+/ICD9–) admissions, compared with 72 (14%) of concordant (CDTA+/ICD9+) admissions (p<0.01).

What is the ICD-9 code for a bacterial infection?

The International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9) code used in this study was 008.45, "intestinal infection due to Clostridium difficile ," and is the only ICD-9 code related to CDAD. To apply this code, medical coders must have documentation in a patient's medical record by the treating medical providers that a patient's gastroenteritis or colitis is due to C. difficile. Positive laboratory tests alone are not sufficient to warrant application of the code. At our institution, ICD-9 coding occurs, on average, 5–7 days after a patient is discharged from the hospital.

What is the ICD-9 code for discharge?

The ICD-9 system of classifying hospital discharge diagnoses is used throughout the United States. The definition for the code 008.45 is consistent between hospitals, although individual coding practices may vary. Although ICD-9 codes have limitations, they are readily available from administrative databases and have been used frequently to identify diagnoses and classify comorbidities (1).

Is there a correlation between C difficile and ICD-9?

Overall, there was good correlation between C. difficile –toxin assay results and ICD-9 codes. Initially, the CDAD rate by ICD-9 codes appeared higher than the rate by toxin assays. However, once the additional CDAD cases identified through chart review were added, this difference was not significant.

Can a CDAD be misclassified?

True CDAD cases may have been misclassified among the controls. A patient who did not have a positive C. difficile –toxin assay, who was not assigned the CDAD ICD-9 code, and whose diagnosis was made by colonoscopy would have been missed. However, misclassification is unlikely for two reasons. First, after charts were reviewed, only 2 additional patients were identified whose diagnosis was made by colonoscopy alone. Second, the detection of CDAD cases transferred from other institutions indicates that CDAD cases diagnosed by methods other than the toxin assays are being captured by ICD-9 codes.
