Quality Assurance on Diagnosis and Therapy of Secondary Immunodeficiencies (SID) in Patients With Chronic Lymphocytic Leukemia (CLL) or Multiple Myeloma (MM) in Germany (QS-SID)

Retrospective, representative registry for quality assurance on diagnosis and therapy of secondary immunodeficiencies (SID) in patients with chronic lymphocytic leukemia (CLL) or multiple myeloma (MM)

Study Overview

Status

Status

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

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

Treatment structure analysis and recruitment (phase 1):

In a first step, data on care facilities, that treat patients with CLL or MM in Germany is obtained.

In phase 1 all centers in Germany that potentially treat patients with the CLL or MM are contacted and data of its facility care level and its number of treated patients is recorded using a one-sided pen-to-paper form. In addition, the willingness of care facilities to become involved in patients' documentation is elicited (phase 2).

Patient documentation (phase 2)

To achieve a reliable, representative sample of patients treated in Germany, the distribution of cases to be documented is specified in the individual indications amongst the facilities involved. This is done using the facilities' data on patient numbers and treatment structure obtained in phase I:

The participating centers are assigned to clusters based on key distinguishing features (facility type, care level and number of patients treated). This sample is modulated according to the previous treatment structure analysis. By taking this approach, the actual percentages of the various care facilities in an indication area can be reflected proportionally in the patient documentation sample.

In phase 2 a electronic case record form (eCRF) is completed in order to collect the original patient and treatment data, which are relevant to the purpose of the study. All data is gathered retrospectively and anonymously using the patient files. Patient and disease related variables (age, general condition according to the Eastern Cooperative Oncology Group (ECOG), relevant comorbidity, staging and relevant mutations), systemic antineoplastic treatment (chemotherapy, antibodies, kinase-inhibitors, relevant co-medication etc.) are recorded. Also, data on diagnosis of Ig-levels (IgG, IgA, IgM), therapy of secondary immunodeficiencies as well as the number and severity of occurred infections and their treatment is collected. Clusters for classification of infections will be developed (e.g. life-threatening, need for hospitalization).

In order to ensure data quality, the scientific project lead will provide training for two employees of the commissioned institute on matters regarding the content of the study. This knowledge will be incorporated into the programming of the user interface and the patient databases so that the program will check for completeness and, as far as possible, plausibility, on the basis of defined requirements and constraints. These checks accompany the process of entering data into the eCRF and allow for validating data instantly. If inconsistencies, mistakes or omissions are detected, data will be validated by an integrated query management system.

Physicians questionnaire (phase 3)

In an additional step and alongside the patient documentation, the attending physicians in participating centers will be surveyed (phase 3) on their competency profile, their assessment of guideline quality and their approach to avoid infections of CLL and MM patients.

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

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Guideline Adherence (GLAD)
Time Frame: Median study observation period of 18.2 months

For SID, immunoglobulin substitution (IgRT) is mandatory only for patients with an IgG level < 4g/l (or IgG subclass deficiency) and additionally more than 3 infections or a severe infection (≥ grade 3) and is optional (may be appropriate) if IgG level < 4g/l and/or 1-3 less severe infections (≤ grade 2). IgRT is not indicated if patients do not fulfil either condition.

Scoring system:

GLAD-Score 2: full guideline adherence GLAD-Score 1: deviations in dose or interval (+/- 10%) or a late start of IgRT (>28 days after a severe infection (≥ grade 3).

GLAD-Score 0: IgRT without indication (overuse) or omitted IgRT despite recommendation (underuse). Likewise, 0 points were awarded if both the dose and the interval deviated from the GL recommendations (e.g. underdosed single dose) or if IgRT was not started until more than 3 months after hypogammaglobulinemia and at least one severe infection.
Median study observation period of 18.2 months

Secondary Outcome Measures

Secondary 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.
Outcome Measure
Measure Description
Time Frame
Guideline Adherence and Susceptibility to Infection
Time Frame: Median study observation period of 18.2 months
For the analysis of susceptibility to infection, the time to next infection was examined using the Andersen-Gill model for recurrent events. For effect estimation, hazard ratios are reported with 95% confidence interval in each case. GLAD-Score 2 is Reference, a higher hazard ratio means a higher susceptibility to infection.
