Incidence and Economic Burden of Clostridium Difficile Infections (CDI) in the German Health Care System (IBIS) (IBIS)

March 14, 2018 updated by: Maria J.G.T. Vehreschild, University of Cologne

Incidence and Economic Burden of Community and Hospital- Acquired Clostridium Difficile Infections (CDI) in the German Health Care System (IBIS)

IBIS is a prospective, observational study, which aims to assess the cost of CDI per day, hospitalization and year including description of incremental costs in hospitalized patients, and recurrent episodes, in German hospitals. Exposure to CDI drugs will not be influenced and remains at the discretion of the treating physician.

In addition to treatment, Health-related quality of life (HRQL) will be analyzed using standardized questionnaires.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Documentation of patient is performed by using the web-based survey platform www.ClinicalSurveys.net which was set up by researchers of the University Hospital of Cologne. This survey platform enables an optimal performance in epidemiological, observational, and interventional trials and is characterized by layered access security and frequent data backup. It has been used for numerous registry and cohort studies with approval of competent authorities and ethics boards.

The following two differences of data documentation are observed:

  1. Retrospective data documentation:

    Data of patients that are too sick to provide informed consent, (up to 30% of all patients enrolled) will be obtained retrospectively, at least 90 days after diagnosis and will be documented in an anonymized fashion. For these patients, documentation of HRQL will not be feasible.

  2. Prospective data documentation:

Data of patients with an informed consent.

The following data items are retrospectively or prospectively documented into our database, depending on if a informed consent exists or not:

  • Demography: age (yrs), gender (m/f), comorbidities (as categories)
  • Charlson Comorbidity Index (CCI)
  • Karnofsky Score (0-100%)
  • APACHE Score for patients in ICU
  • Number of hospitalizations in the past 12 months prior to the CDI index episode
  • Type and duration of antibiotic treatment during the last 3 months
  • Diagnostic measures (microbiological tests, imaging, endoscopy) leading to diagnosis of CDI
  • Severe and/or complicated CDI (Severe: white blood cell count ≥15 × 10³/μL and/or an increase in creatinine ≥1.5 times the baseline level; complicated: at least 1 of the following: hypotension requiring vasopressors, ICU admission for a complication of CDI, ileus leading to installation of a nasogastric tube, toxic megacolon, colonic perforation, or colectomy)
  • Bowel movements: frequency and consistence according to Bristol stool scale (see appendix 1)
  • Treatment for CDI: substance, dosage, frequency, duration
  • Other antibiotic treatment: substance, dosage, frequency, duration
  • Diagnosis of CDI recurrence: time point, diagnostic measures
  • Treatment of CDI recurrence: substance, dosage, frequency, duration
  • Duration of hospitalization: overall, types (general, intermediate care, intensive care, bone marrow transplantation)
  • Mechanical ventilation (y/n)
  • Days with contact isolation
  • Days in single room
  • Adverse drug reactions
  • Health-related quality of life (HRQL) as determined by Garey et al. J Clin Gastroenterol 2016 (for prospective analysis only)

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Hospitalized patients with a CDI episode in German hospitals

Description

Inclusion Criteria:

  • Index episode of CDI based on

    • the presence of diarrhea (defined as ≥3 unformed bowel movements/24h) plus
    • an enzyme immunoassay (EIA) detecting Glutamate dehydrogenase (GDH) or polymerase chain reaction (PCR) for toxin B test plus
    • a positive EIA for toxin A and B
  • Ongoing or new hospitalization at inclusion into the study.
  • Written informed consent (IC) has been obtained from the study subject or a legal representative.

Exclusion Criteria:

  • Patient with any social or logistical condition which in the opinion of the investigator may interfere with the conduct of the study, such as incapacity to well understand, not willing to collaborate, or cannot easily be contacted after discharge.
  • CDI episode within the previous 84 days.

What is the study measuring?

Primary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
