Introduction

Strengthening Laboratory and Epidemiology Collaboration

May 2007


Learning objectives

At the end of this presentation, participants should know:

  • The goal of this course

  • The specific objectives of the course

  • The methods used during the course


Why this course?

Public health is multidisciplinary

  • Epidemiologists, clinicians, laboratory specialists, environmental specialists, entomologists, veterinarians, nurses

    Specialists may have different

  • Skills, knowledge, working habits, perspectives

    Specialists need to collaborate often on

  • Surveillance, outbreak investigations, studies

    Activities must be coordinated to reach common goals


Conditions for successful collaboration

Identify common goals

  • Applied public health (action)

  • Research

    Understand that there are different perspectives

    Recognize different skill sets

    Respect different working cultures

    Communicate effectively


Module Objectives

To facilitate communication and collaboration between epidemiologists and the laboratory by:

  • Providing epidemiologists with basic training in microbiology techniques and analysis

  • Providing epidemiologists with the laboratory perspectives of public health investigations


Specific objectives

  • Develop field epidemiologists’ knowledge of basic laboratory sciences

  • Identify ways to have better collaboration between the laboratory specialists and the epidemiologists

  • Prepare the epidemiologist to ask the right questions when collaborating with laboratory specialists


Field epidemiologists should be able to:

  • Engage in positive interactions with laboratory specialists

  • Identify appropriate samples to collect

  • Appropriately collect, label, package and transport specimens

  • Identify key laboratory investigations for selected syndromes and/or suspected pathogens

  • Identify when and which typing methods should be used


Field epidemiologists should be able to:

  • Identify the need for and use of antimicrobial susceptibility testing

  • Identify the role of the laboratory in public health surveillance

  • Understand the role of laboratory quality assurance

  • Interpret laboratory test results: sensitivity, specificity and causality criteria


1. Engage in positive interactions with the laboratory

  • Understand why and when to engage the laboratory

  • Learn how to communicate with the laboratory by learning their language

  • Take into account the needs, objectives and perspectives of the team:

    • Laboratory specialists, clinicians, veterinarians, environmental specialists, entomologists


2. Identify appropriate samples to collect

  • Think critically while working with laboratory specialists

  • Identify surveillance, clinical, laboratory needs

  • Estimate the number of samples needed to confirm the cause of the outbreak

  • Define sampling strategy - mode of transmission, syndrome

  • Seek external advice for atypical scenarios

  • Collect samples ethically


3. Appropriately collect, label, package and transport samples

Identify criteria to select an appropriate laboratory

  • virulence, type of testing, location, time, needs (diagnostic vs specialised testing)

    For each type of sample, know:

  • Collection protocol

  • Documentation, labeling requirements l

  • What to include (patient, outbreak information, tracking system)

  • Appropriate bio-safety packaging and transportation requirements (UN)


4. Identify key laboratory investigations for selected syndromes and/or suspected pathogens

  • Understand advantages and disadvantages of key microbiological methods

  • Understand basic immunology principles

  • Understand use of microbiological techniques as epidemiologic tools :

    • Time frame for antigen/pathogen detection

    • Windows for antibody detection

    • Time required to obtain results

    • Cost, sensitivity, specificity and limitations


5. Identify when and which typing methods should be used

  • Identify typing methods that can:

    • Confirm the existence of an outbreak (e.g. when epidemiological methods are insufficient)

    • Identify the cause of disease (e.g. environmental reservoir)

    • Describe the phylogeny of pathogen


6. Identify the need for, and use of, antimicrobial susceptibility testing

  • Understand anti-microbial resistance and implications for antibiotic use

  • Understand when to ask for antibiotic resistance patterns

  • Understand the need for laboratory-based surveillance for antibiotic resistance

  • Interpret antimicrobial resistance results in a public health context


7. Identify the role of the laboratory for public health surveillance

  • Understand the principles of laboratory-based surveillance

  • Understand how the laboratory contributes to surveillance


8. Understand the role of laboratory quality assurance

  • Think critically about laboratory quality assurance

  • Think critically about laboratory methods

    • Ensure that the corresponding laboratory has the highest possible level of quality assurance


9. Interpret laboratory test results: sensitivity, specificity and causality criteria

  • Understand sensitivity, specificity and causality criteria

  • Interpret laboratory results according to:

    • Sensitivity and specificity

    • Context

    • Incidence/prevalence of the disease

    • Host-pathogen relationship


Content of the Module

  • Lectures

  • Case studies

  • Communication exercise


Lectures

  • Sampling strategies

    • Communication

    • Sampling strategy

    • Specimen management

    • Interpretation of the results

  • Management of an outbreak where the pathogen may be unknown


Communication exercise

  • Johari windows technique

    • Understand each other’s perspective when epidemiologists work with laboratory specialists
