The Cohort Review Process The Cohort Review Process
Kim Field RN, MSNWA State DOH
Tuberculosis Program
Objectives
• Define the cohort review process• Outline the roles key TB control staff play• Identify how to adapt and implement the
cohort review method in your program area
What is Cohort Review
• Cohort review is a systematic review of patients with tuberculosis (TB) disease and their contacts.
• A “cohort” is a group of TB cases and contacts identified over a specific period of time, usually 3 months.
• The cases are reviewed approximately 12-15 months after they are reported, so that many of the cases and contacts have completed or are nearing the end of treatment.
“The fundamental concept of a cohort review is accountability.
Staff are accountable to supervisors and to the program for how well they are caring for patients...
and the program is accountable to patients and to the public for controlling TB.”
Thomas Frieden, MD, MPH
Director of CDC
Former New York City Commissioner of Health

Cohort Review Process
• Group process, using staff from every level of the organization
• Individual and group accountability • Proactive process • Closely tied to state and national TB goals
and indicators
During cohort review presentations• Listen carefully to all case
presentations• Review available support
documents– TB registry, case
management forms, medical records.
• Ensure that all aspects of case management adhere to department of health policies and procedures.
Presenter Medical Reviewer
Purpose
• Improves case management at the local level• Uses cohort review as a tool to conduct program
evaluation• Connects case discussions with performance
summary report• Helps program reflect on performance - think about
the big picture• Engages a wider audience (e.g., disease
investigators) in discussions surrounding program-wide issues
During cohort review presentations
• Review case, diagnosis and treatment:–Pulmonary or Extrapulmonary–Culture confirmed or Clinical case–AFB smear/culture result –Drug regimen is appropriate –Drug Susceptibility results are obtained –Drug regimens are adjusted if necessary–Sputum conversions are documented–Treatment completions are documented
Cohort Review Process Goals
• Evaluate process of public health intervention to:-ensure appropriate drug regimen used -ensure timely treatment completion -improve timeliness of interventions -shorten time of contact identification and screening -improve management of infected contacts -analyze outcome to develop appropriate
interventions
Cohort Review Process Strengths
• MD reviews every case • Public accountability for case management
and follow-up of contacts • National objectives are tracked • Can be modified to add/delete measurable
items• Consistent with global principles of TB control
During cohort review presentations• Assess outcomes• Use teachable moments to illustrate important lessons
in effective TB control
– use specific cases as examples of how certain problems should be handled.
– give feedback to staff and – update staff on policies,
protocols, and scientific changes.
Implementation of Cohort Review in Washington
34 Local Health Jurisdictions (LHJs) for 39 counties – all counties participated in training
Why Implement Cohort Review?
• Increase learning for staff • Improve case management at state, local levels • Improve documentation in clinic records • Use cohort review as a tool for program evaluation • Create systematic platform for case mangement
and data analyis • Decrease TB morbidity
Detailed Case Review
Facilitators ask questions to make sure that:
• Details are consistent
• Regimen is appropriate
• Treatment is completed
• Contact investigation is thorough

• TB cases identified• Treatment started• Contact investigation initiated
• Ongoing treatment of patients with TB disease• Contacts evaluated and started on treatment, as necessary
• TB disease treatment completed• Infected contacts continue on treatment for LTBI
1st quarter contacts complete treatment
• Begin follow up on issues identified•Cohort prep
COHORT REVIEW SESSION
• Continue follow up on issues identified during cohort review session
• Treatment completion rate presented for contacts of cases from previous 1st quarter
How do we go from raw data to the summary analyses?
• TB Morbidity data sources-Cases: TIMS and as of January 2009 PHIMS (Public Health Information Management System)-Contacts: WA State contact Database
• Cohort review forms adapted to collect additional measures (e.g. timeliness) stored in an excel file
• SAS software used to analyze all data • Enter the output into summary spreadsheets
Preparation of Cohort Sheets
TB programs basically collect the same information; our processes might be different but the information needed
should be available.
• Begin form completion as you begin working the case, it saves time
• Most of the case information will be complete or near completion at time of the review
• It allows for a final review of case• It should take approximately 10 minutes to complete a
review sheet
Analysis of Outcomes
• Analyze data on outcomes of interest
• Obtain missing or update incorrect data
• Discover challenges and opportunities as a
program •Focus on big picture:
– Could we have done things differently?– How can program better support the staff
• Record and summarize meeting
Cohort Practice: Mock Cohort
• Cases are called in the order listed in notification
• Supervisors act as medical reviewers• Staff are given 1 week to make changes and
return corrected sheets to supervisors• A 2nd practice session is held 2 weeks prior to
actual cohort (if needed)• 1 week prior to cohort review the sheets are
forwarded for data entry
Modifications:Timeliness Measures for Cases (1)
Average number of days: Sputum collected and received at lab Sputum smear + and cavitary CXR to TB
medications started For cases with MTD testing, sputum
collection to TB medications started
Modifications:Timeliness Measures for Cases (2)
Average number of days: Sputum smear + to case reporting from private
provider to LHJ Sputum smear + to reporting from lab to LHJ Sputum smear + to case reporting from LHJ to
DOH MTB culture + to reporting drug susceptibility
from lab to LHJ
Modifications:Timeliness Measures for Contacts
Average number of days: Sputum smear + and
cavitary CXR to date contacts identified
Of the 124 TB cases counted in Pierce County from 2003-2007:
• 71% were foreign-born from countries with high endemic rates of TB
• 73% had infectious pulmonary TB• 15.7% of the cases that had drug sensitivity
testing done were INH resistant
Cohort Review: A Local Health Department Perspective (2)
The TPCHD staff report that since participating in the the cohort review process they have:
• established the need to set priorities for program funding and activities
• improved program evaluation with documentation of meeting local and state objectives
• increased case management accountability for both patients and contacts
• identified gaps and barriers to care

Impact of Cohort Review: HIV Testing
• 2000 - 36% of all TB cases did not have an HIV test• 2008 – 11% of TB cases did not have an HIV test
Impact of Cohort Review: DOT
• 2000 - DOT done on 76.9% of all cases • 2007 – DOT done on 92% of all cases (100% smear+)

2009 Pilot Project: Enhancing the Cohort Review Process with NTIP Objectives
Aftermath of Cohort
• Post your data• Select indicators that need improvement• Select actions to initiate and plan
implementation of actions – what process will you use, how will you evaluate results?
• Document results of implementation – did you get the desired results?
• Begin again
Summary Measurable improvement in meeting local,
state and national TB objectives through the use of the cohort process
Successful cohort review
The medical reviewer assist in…
• Improving patient care• Improving TB control program • Improving Public Health
…first steps toward TB elimination
