Self-Study Modules for Effective TB Interviewing

The TB interview

The TB interview is initiated to identify contacts at risk of exposure to refer for medical evaluation for TB infection or disease.  Because of this goal, only certain patients need to be interviewed.  These include patients who

  • Have been diagnosed with verified TB (excluding most forms of extrapulmonary TB, but including pleural effusion or miliary TB with cough and laryngeal TB);
  • Are suspected of having pulmonary, laryngeal, or pleural TB;
  • Have been diagnosed with any form of verified TB, abnormal chest x-ray, positive tuberculin skin test which indicates recent TB transmission (for example, a documented converter who has developed disease or a young child).

The TB interview is conducted with individuals who may have put others at risk of contracting TB.  In addition, if there is evidence of recent TB transmission, a source case investigation may be initiated.  Like a contact investigation, this process attempts to locate a patient’s contacts, referred to as associates.  In this case, the associate is viewed as the “source,” or the person who transmitted TB infection and not the recipient of TB infection due to prolonged exposure to the index case.  For this reason, it is recommended that interviews be conducted with the following groups: parents or guardians of children 2 years of age and younger who have TB infection, and children 4 years of age and younger with TB disease or chest x-ray findings consistent with TB-related abnormalities.  Guidelines for interviews for source case investigations are covered in Module 4. 

Prioritizing Interviews

Once it has been determined who will be interviewed, priority must be assigned to the interviews.  All interviews should be initiated within 72 hours of TB suspect/case report.  Follow-up interviews may occur to obtain additional information.  A second complete interview or re-interview should be done within 2 weeks of initial interview to determine additional information that the patient may not have shared for various reasons and to confirm previously obtained information.  The infectiousness of a patient and his or her ability to transmit disease is the main consideration for prioritizing the interview.  Infectiousness is determined by

  • Site of disease (pulmonary, pleural effusion, miliary TB with cough, or laryngeal TB);
  • Presence of cavitary disease;
  • Positive acid-fast bacilli (AFB) sputum smear;
  • Positive TB culture;
  • Presence of cough or hoarseness;
  • No treatment, recently started treatment, or inadequate treatment; and
  • Length of time of symptoms.

Source case interviews take lower priority than interviews with infectious cases.  However, this may change if the number of skin test conversions or occurrence of new TB cases is high in a particular setting.  This will be covered in Module 4.  Other considerations, which may also influence priority of interviews, are location of the patient, ability to locate the patient in the field, the patient’s history of nonadherence, and number of interviewers available.

Infectious Period

In order to bring focus to the interview process, the infectious period must be determined.  This period is a time frame in which potential exposure to others may have occurred while the patient was infectious or able to transmit TB.  Often, the beginning of the infectious period is when the onset of symptoms occurs, especially coughing.  Local or state standards should be used to determine the beginning of the infectious period.  Some health department guidelines denote a specified period prior to the patient recollection of the onset of symptoms, particularly coughing. 

For the purpose of the contact investigation, the end of the infectious period is determined by the existence of all of the following criteria

  • Symptoms, such as frequency and intensity of cough, have improved
  • Patient has been receiving adequate treatment for at least 2 weeks
  • Patient has shown some evidence of a bacteriological response, such as the reduction of the grade of the AFB sputum smear or negative sputum smears
  • Exposure to contacts has ended

The infectious period should be stated in the form of start date to end date.  The infectious period provides a timeframe for the patient when identifying information on contacts.

The determination of the infectious period is based on several factors and should result from a collection of all relevant information from both the patient and the patient’s medical record.  The infectious period may exceed 6 months; however, the patient’s memory of details beyond that time frame may be unreliable.  Regardless, if review of the patient’s medical record or other source indicates that the patient has had signs and symptoms of pulmonary or laryngeal TB for more than 6 months, collection of contact and congregate setting information prior to that time should be done.  Using a retrospective timeline, the results of contact evaluations will help determine when to stop identifying more contacts. This timeline should start with the date of the interview and work its way back in time. 

A patient will most likely not be able to provide you with exact onset dates for symptoms.  Asking the patient to associate symptoms with events may assist.  For example, a patient can be asked if he or she remembers coughing around a major event or holiday (e.g., his or her birthday, Christmas).

In a source case investigation for a child, the infectious period generally begins 3 months prior to the date of the interview.  The infectious period end date is the interview date.  The factors regarding treatment and sputum conversion for ending the infectious period in source case investigations do not apply because most young children, as well as persons with latent TB infection, are not usually infectious.

Use of Respiratory Protection

The infectiousness or potential infectiousness of a patient should be taken into consideration by the interviewer, not only for the purpose of eliciting contacts, but also for assessing the need for respiratory protection.  Appropriate respiratory protection should be used when interviewing an infectious or potentially infectious patient. However, the use of respiratory protection may cause difficulty in establishing rapport with a patient, as some patients may be offended.  If respiratory protection is used, the interviewer should explain to the patient why its use is necessary.  For additional information regarding the infectiousness of patients, please consult the CDC resource, Self-Study Module on Tuberculosis #5:  Infectiousness and Infection Control.

There are two basic types of respiratory protection that may be utilized during contact investigation:

  • Personal Respirators – There are a variety of personal respirators available.  The most commonly used personal respirator in a healthcare setting is the disposable N-95 respirator.  Research has shown that use of a surgical mask is not adequate in capturing all TB bacteria.  Some surgical masks fit poorly and, therefore, provide very little protection from any airborne hazards.  Personal respirators should be used by the interviewer around an infectious patient.  Different varieties of personal respirators are available.  Staff should be trained on the appropriate method of wearing respirators and be fit tested according to their institutional policy.  A personal respirator should not be worn by a patient, since it may result in increased difficulty in breathing for the patient and is generally more expensive than a surgical mask.
  • Surgical Mask – These masks should be used by the infectious patient and may prevent
    M. tuberculosis bacteria from spreading.  However, surgical masks can be loose fitting and, depending on the proximity of an individual to the patient, may not be an adequate barrier for all M. tuberculosis bacilli.

In situations involving infectious or potentially infectious patients, personal respirators should always be worn by interviewers and surgical masks should only be worn by patients.  There are a number of different factors that affect the use of respiratory protection by the interviewer and patient.  Detailed below are several common contact investigation scenarios with infectious patients, and the correct use of respiratory protection for each scenario:

  • Interview in an infectious patient’s home – While many infectious patients are hospitalized, this is not always the case.  The patient should be wearing a surgical mask at home if he or she is living with others.  In this situation, after entering the home, the interviewer should wear a personal respirator.  The interviewer should not put on a respirator outside the patient’s home because it may draw attention from outsiders. Even though the patient’s mouth and nose are to be covered by a mask at all times, the interviewer cannot assume that the patient is always masked and should take adequate precautions.
  • Interview in an airborne infection isolation (negative pressure) room (AIIR) in a hospital – In this case, the patient is considered infectious.  The patient should not be asked to wear a mask in this situation, but should be instructed to cover his or her mouth with disposable tissue while coughing. Any person entering the room should wear a personal respirator (e.g., N-95).
  • Interview in a clinic setting in both AIIR and non-AIIR – A patient can arrive at a clinic setting and be deemed infectious or potentially infectious based on symptoms, particularly a productive cough.  In this case, the patient should be immediately triaged into an isolation room, that is, away from other patients.  A surgical mask should be given to the patient for use as he or she proceeds through the clinic, and the patient should be instructed to cover his or her mouth with disposable tissue while coughing.
    • In an AIIR – As above, the patient may remove the surgical mask, but the interviewer should wear a personal respirator.
    • In a non-AIIR – The patient should wear a surgical mask and the interviewer should wear a personal respirator.

As noted above, the use of a surgical mask or a personal respirator may affect the rapport between interviewer and patient.  Explaining the need for protection and acknowledging that surgical masks or respirators may be uncomfortable can help in re-establishing rapport.  Out of respect to the infectious patient at home, an interviewer should not put on a respirator prior to entering the home, in sight of neighbors or passers-by.  The respirator should be worn upon entering the home.  The interviewer can say to the patient, “I hope you don’t mind, but I need to wear my respirator while I am here visiting you today.”  If the patient questions the reasons, particularly if he or she is already wearing a surgical mask, the interviewer can explain, “I am glad that you are wearing your mask.  However, it may not prevent all TB germs from spreading.  That is why I need to take precautions.  If, in a few weeks, you are no longer spreading germs, I will not need to wear this respirator.” 

Structure of the Interview

The interview has five components, which are presented in detail in pages 8-17.  The components are as follows:

  1. Pre-Interview Activities
  2. Introduction
  3. Information and Education Exchange
  4. Contact Identification
  5. Conclusion

At the end of this module is a checklist that summarizes the elements of the interview (page 25).  This checklist can be used during the interview as a prompt and after the interview to evaluate whether the interview was complete.  Note that some interview elements may vary depending on what information is required by the local health department.  Information the interviewer provides to the patient may depend on the job responsibilities of the interviewer, including a combination of medical care, directly observed therapy, and congregate setting investigation. 

I. Pre-Interview Activities

Before conducting the interview, the interviewer should organize and prepare for it by obtaining background information on the patient.  This will assist the interviewer in forming a preliminary infectious period and developing an interview strategy.

  1. Review medical record – The record may contain information from hospital staff, infection control practitioners, or social workers.
    • Review and note medical record information related to the diagnosis (site of disease, symptom history, bacteriologic and chest x-ray results, treatment, and recent or past known exposure to TB, including skin test results)
    • Review and record social history, language and cultural barriers, and other medical conditions
    • Note previous hospital admissions and any history of previous treatment, substance abuse, mental illness, or inability or unwillingness to communicate with other healthcare staff who may have interacted with the patient
    • Assess the need for respiratory protection during the interview for both the interviewer and patient
    • Obtain and record index patient locating information:
      • Record name, address, telephone number, and additional locating information
      • Collect and record next of kin, emergency contact, employer
  2. Establish a preliminary infectious period based on medical record review and local health department guidelines.  This will be refined during the interview based on the patient’s verification of information.
  3. Develop a strategy for the interview process by analyzing information collected thus far.  This should include looking for any unusual factors about the patient that will need to be considered, such as any other medical conditions, mental status, housing or money, transport, and social support needs. 
  4. If possible, arrange an interview place and time convenient to the patient and satisfactory to the local health department time frame for the completion of interviews.
  5. Arrange and ensure privacy by seeking an interview time and place with minimal distractions and interruptions.  Note: When a patient is hospitalized, the initial interview should take place in this setting.

II. Introduction

As discussed later in Module 2, “Basics of Communication and Patient Education,” the very first interaction with the patient can influence the remainder of the interview.  It is important from the beginning for the interviewer to provide an explanation of who he or she is and present a clear picture of the importance of the TB interview.

  1. Begin by building trust and rapport, as well as demonstrating respect. Introduce yourself and provide a business card or identification.  If appropriate, shake the patient’s hand.  Greet the patient using Mr./Ms. and family name and then ask the patient what he or she would prefer to be called.  Explain your role in the tuberculosis control program. This includes your responsibility to protect the health of the public.
  2. Explain that the purposes of the interview are
    • To provide TB information and answer any patient questions, and
    • To identify people who have been exposed to TB so that they can be referred for medical evaluation.
  3. Emphasize confidentiality, yet inform the patient that relevant information may need to be shared with other health department staff or other people who may assist in congregate settings to most efficiently ascertain which contacts need to be evaluated. Also, note local laws regarding confidentiality when interviewing minors.

III. Information and Education Exchange

As the interview progresses, the interviewer should educate the patient on TB and the contact investigation process.  As this occurs, the interviewer should continuously assess whether the patient understands the information being exchanged and appears invested in the interview process.

  1. Throughout the interview, determine the extent of trust and rapport being developed while observing the patient and assessing responses.
  2. Observe the patient’s body language and speech for comfort level and comprehension of information provided.
    • Make note of any physical signs or behavior indicative of alcohol or substance abuse, nutritional status, lifestyle, and other conditions which may influence the patient’s level of cooperation
    • Assess the patient’s communication skills, attitudes, concerns, and needs.  As necessary, refine the interview strategy.  This may include accomplishing less during the initial interview session and scheduling a follow-up interview
  3. Personal information – Explain that it is important to obtain and confirm the patient’s personal information.  The following patient information should be collected and verified:1
    • Full name
    • Alias(es)/nickname(s)
    • Date of birth
    • Place of birth (city, state/province, country)
    • If born in a foreign country, date arrived in USA
    • Travel destinations (when last there and for how long)
    • Physical description (height, weight, race, other identifying characteristics)
    • Current address and post office (PO) box or place of residence, including directions, if necessary
    • Telephone number
    • Length of stay at current address
    • Marital status
    • Next of kin (name, address, telephone number, other locating information)
    • Emergency contact (name, address, telephone number, other locating information)
    • Employer or school (name, address, telephone number, other locating information)
  4. Medical information and problem indicators
    • Explain the importance of collecting accurate medical information
    • Obtain and document the following patient information:
      • Known exposure to TB (who, where, when) or knowledge of anyone with similar symptoms
      • Past hospitalization(s) for TB (name, admission and discharge date[s])
      • Other medical conditions, including HIV test results, if available
      • Substance abuse (including frequency, type, how long)
      • Medical provider for TB (private or clinic, name, address, telephone)
      • Transportation availability to/from medical provider
      • Directly observed therapy (DOT) plan, if known (where, when, by whom)
      • Barriers to adherence
    • Disease comprehension
      • Use open-ended questions to determine the patient’s TB knowledge
      • Reinforce the patient’s TB knowledge and correct any misconceptions.  Explain mode of transmission and how TB affects the body, using language the patient can understand.  Avoid using medical terms and recognize when to defer questions to appropriate personnel (see Module 2, “Basics of Communication and Patient Education”).  Provide appropriate patient education materials.
    • Symptom history – Review with the patient the following TB-related symptoms, including onset dates and duration:
      • Cough
      • Hemoptysis (coughing up blood)
      • Hoarseness or laryngitis
      • Unexplained weight loss
      • Night sweats
      • Chest pain
      • Loss of appetite
      • Fever
      • Chills
      • Fatigue

        Recall of symptom onset can generally be poor. Mentioning prominent dates and major holidays can help the patient recall symptom onset.  Cough, if present, is the most critical symptom in determining the infectious period.
    • Discuss the elements of patient’s current diagnosis, including
      • Tuberculin skin test results
      • Site of disease
      • Symptom history
      • Chest x-ray and bacteriologic results
  5. Disease intervention behaviors – Explain the importance of the following interventions: 
    • Treatment regimen
      • Explain that the patient’s medications kill TB germs when taken as prescribed.  Reinforce the personal and public health benefits of taking the medicine.
      • If trained to do so, identify and explain each prescribed drug and discuss potential side effects.
      • Establish a specific schedule or reinforce existing schedule for outpatient treatment, including DOT.
      • Review the local/state regulations mandating treatment adherence (if applicable).
    • Infection control measures
      • If the patient is infectious, review the importance of cough hygiene, e.g., using a mask or a tissue to cover the mouth and nose if coughing and sneezing.  Explain proper disposal technique.  Emphasize that covering the mouth and nose is an important measure the patient can take to protect others.
      • Discuss the importance of adequate ventilation to protect others.
      • Describe other measures as appropriate, i.e., home isolation, visitors to the home, and return to work or school.
    • Maintaining medical care – Discuss the importance of
      • Adherence to therapy while reemphasizing the significance of continuity of therapy;
      • Sputum collection, chest x-rays, and physician evaluations;
      • Adherence to all medical appointments and DOT, if ordered; and
      • Adherence-enhancing strategies, e.g., available incentives, pill boxes, and reminder notes.
  6. Infectious period
    • Based on the information collected thus far, refine previously established infectious period.
    • Review significance of infectious period with patient and discuss its role in contact identification.


IV. Contact Identification

While a brief explanation of a contact investigation should be provided at the beginning of the interview, a reemphasis prior to the elicitation of contacts is necessary.  This reassures the patient of the importance of providing contacts’ names.  It is also important at this time to reinforce confidentiality and to educate the patient on TB transmission.

  • Introduce the contact identification process by reviewing the patient’s understanding of TB transmission.  Stress the importance and urgency of the rapid and accurate identification of all priority contacts during the infectious period. Reinforce the importance of identifying contacts in order to protect family and friends from getting TB.
  • Explain the difference between priority and nonpriority contacts.  This should include a discussion of how TB is spread.  It should be emphasized that transmission increases with duration and frequency of exposure and with exposure in closed spaces.  These concepts should be explored with each named contact.
  • Inform the patient that a congregate-setting investigation may be done in any place in which the patient reveals having spent prolonged time during the infectious period.  The patient should be made aware that an appropriate site manager (e.g., supervisor, school principal) may be called in to assist in identifying persons in this setting, but that an emphasis on confidentiality will be maintained. With other medical conditions, the patient’s illness and identity are held in strict confidence. For an infectious disease such as TB, working with a third party in a congregate setting may be appropriate.  The patient should know that if he or she chooses to tell others about his or her illness, or if others already know about the diagnosis, the health department will continue to maintain confidentiality and not reveal or confirm any patient information. 
  • Collect information about the patient’s contacts in the household/residence, workplace/school, other congregate settings, and social/recreational environments.  If the patient’s responses contain conflicting information, ask about these inconsistencies in a nonconfrontational manner.  Be aware that patients are being asked to recall detailed information over an extended period of time and may not remember information very clearly.  Some patients, however, may intentionally provide vague or inconsistent information.  In this case, the interviewer should re-emphasize the importance of contact identification and confidentiality (see Module 4 for additional strategies).

Contact tracing information – Obtain the following information as relevant to the patient’s infectious period (some information will require a field visit for confirmation):

  • Type of housing (e.g., house, apartment, shelter, nursing home)
  • Description of housing, including size of rooms, ceiling height (low or high), number of rooms, method of ventilation, and source of heating and cooling
  • Additional addresses where patient spent time
  • If employed: employer name, address, telephone number, full or part-time, hours per day/week, how long employed, transportation type to/from work, length of commute, occupation/type of work, indoor or outdoor work space, and enclosed or open work space
  • If unemployed: source of income
  • If attending school: name of school, address, telephone number, grade/year, hours per day/week, transportation type to and from school, and length of commute
  • Social and recreational activities (e.g., hangouts, bars, team sports, community centers, band, choir, place of worship), including hours per day/week, and means of transportation
  • Other congregate settings (e.g., armed services, hospital, nursing home, drug treatment center, detoxification center, shelter, group-living home, hotel, prison or jail), including name and dates of attendance
  • Travel history (where, with whom, mode of transportation, person visited)

Eliciting Contacts

Contacts’ information should include locating and physical identifying details.  Explain to the patient that the reason for collecting detailed information on each contact is to be able to locate these individuals as easily and quickly as possible and not to mistake them for others. Information should be gathered in three spheres:

  • Household or living situation
  • Workplace or school
  • Social and recreational

The patient may not be able to provide full names or any names for some contacts, so the investigator who must locate the contacts in the field may need to rely on nicknames or physical descriptions, or both.  Note that the patient may not be able to supply all of the details listed below and that the interviewer should decide how much information is needed based on what has already been collected.

Obtain the following information for activities occurring within the patient’s infectious period about all persons in each sphere. Information should include name/alias(es)/nickname(s), relationship to patient, age, sex, physical description, employer/school, and other locating information (include current address if no longer living in the household).  Also, include hours of exposure per week and date(s) of first and last exposure.  Include, with identified contacts, persons regularly socialized with and social/recreational establishments, including

    • Close friends
    • Sex partners
    • Overnight guests and regular visitors to patient’s residence (e.g., neighbors,
      friends, and relatives)
    • Persons with whom drugs are used
    • Overnight visits to any other location(s) (obtain address[es])
    • Specifically ask about time spent with young children or immunocompromised individuals
  • Congregate setting assessment
    • Ask for a description of identified congregate settings, including size of rooms, ceiling height (low or high), number of rooms, method of ventilation, source of heating and cooling.
    • Inform the patient that it will be necessary to make site visits to the home, workplace or school, and leisure establishments to assess the shared air environment to accurately structure the contact investigation. 
    • Stress patient confidentiality as well as the necessity of sharing information on a need-to-know basis with appropriate site management.  Discuss the importance of a medical evaluation for each contact.
  • Methods of referral
    • Inform the patient that referrals and verified contacts’ medical evaluations should be carried out immediately 
    • Explain contact referral options (options may vary by state):
      Patient should be given a choice of whether to inform contacts of their risk of exposure prior to the health department referral process.  Discuss the referral options with the patient, deciding which contacts are appropriate for health department referral and for patient referral.  Review with the patient how and when contact referrals will be made and where the contacts will be referred.

      Health Department Referral: While protecting the patient’s right to privacy, the healthcare worker assumes full responsibility for locating and informing the contact about exposure and the need for a medical evaluation.

      Patient Referral: The patient agrees to inform the contacts about exposure and the importance of speaking with the healthcare worker regarding the need for a medical evaluation.  Remind the patient that this method will not protect his or her confidentiality.  If necessary, rehearse with the patient how to inform contacts and what instructions they should be given regarding their medical evaluations.  Inform the patient that the health department will follow up on anyone who does not respond within an agreed upon timeframe.

      Explain that the index patient’s identity will be held in confidence during the investigation, and the same is true for all contacts’ confidentiality.  The health department cannot reveal the results of medical evaluations (e.g., how many people are tuberculin positive, how many people have TB disease, who has been started on treatment) of contacts to the index patient, other contacts, or staff of congregate settings.
    • Discuss re-interview time frame:
      Explain that you will be visiting the patient again upon discharge from hospital, or within 10-14 days if the initial interview is at home, to obtain further information and answer additional questions. 

V. Conclusion

Conclude the interview in a positive manner.  Recognize the index patient’s participation in the interview, and make the patient feel that you are trustworthy and can be consulted with concerns as they arise, even after the interview. 

  • Request and answer the patient’s questions.
  • Review and reinforce all components of the treatment plan.
  • Evaluate the patient’s remaining needs or potential adherence problems.
  • Restate the date of the next medical appointment, if known.
  • Arrange for both a re-interview and home visit, if not already completed.
  • Reinforce the procedures for referral of each contact.
  • Provide information on how the patient can contact you.
  • If appropriate, shake the patient’s hand, express thanks and appreciation, and close the interview.

While it is important for the interviewer to follow a systematic process to achieve the interview objectives, it is also important for the interviewer to demonstrate flexibility and respond to the patient’s needs.  The patient may have questions, show signs of fatigue, or need assistance in some way, which may lead to a deviation from the interview agenda. Addressing these needs through recognition of concerns, problem solving, and referral to appropriate resources may be a minor set-back, but can eventually allow the interview to progress.  For strategies on dealing with patient needs, see Module 4, “Special Circumstances.”


It is possible that not all information will be collected in the first interview with the patient.  Even if the interviewer conducts a comprehensive first interview, a second interview should be completed.  A second interview will allow the patient to recall any further information that may assist in the contact investigation and may facilitate additional questions for the interviewer.  If the first interview was conducted in the hospital or health department, the second interview should be done in the patient’s living space, such as a home, apartment, shelter, or correctional facility.  Observations made in a patient’s living space can provide additional information about contacts, as well as identify or confirm any environmental information that can aid in decisions about transmission and testing.  The patient may also feel more comfortable participating in an interview in a familiar environment, and may provide information more readily.  In between interviews, the interviewer should ask the patient to make notes of questions, concerns, additional contacts, and other topics to be addressed at the time of the re-interview. In addition, the interviewer’s contact information should be provided to the patient so that the patient can contact the interviewer with any additional information or questions.

Before a re-interview, do the following:

  • Review original interview documentation
  • Identify gaps in first interview that need clarification
  • Review infectious period to ensure all time is accounted for in collected information from the patient
  • Formulate a strategy as was done for the first interview
  • Clarify known contact information to plan additional questions.

Assessing for Additional Contacts and Risk of Transmission

While conducting a re-interview, the interviewer can evaluate environmental characteristics of the place in which exposure occurred, and may be able to obtain additional information about identified contacts, as well as identify additional contacts. 

During a re-interview, the interviewer should

  • Continue building trust and rapport;
  • Provide additional TB education, as needed;
  • Observe environmental characteristics such as room size, crowding, and ventilation, to estimate the risk of TB transmission;
  • Identify additional contacts, especially children and immunocompromised persons; collect their locating and identifying information, such as phone numbers, addresses, and physical descriptions;
  • Look for evidence of other contacts who may not be present at the time of the visit.  Evidence may include photographs, toys, extra jackets, and shoes. In addition, take notice of trophies or plaques, as well as other items that may suggest outside leisure activities in which the index patient participates;
  • Verify previously identified contact information by observing characteristics of who is present;
  • Follow up on contact referrals already made; and
  • Discuss any problems with locating previously identified contacts.
