Competency Assessment Tool for

Outbreak Investigations

TOOL INDICATORS

Is it an outbreak?

Timeliness of Response by Rapid Response

Team

(Verification of rumor / media alert done or not)

Was the outbreak informed/ identified by weekly data analysis?

Period between date of start of outbreak and date of response (first reported to a health worker at any health facility)

Composition of outbreak response team

Laboratory confirmation of outbreak

Type of clinical specimen

Transport media

Results

What working case definition was used?

Case definition

Active case finding Was active house to house case search done?

What population was covered?

Line listing to compile cases from health facility records and active case search

Use of epicurve, spot map, graphs?

Description of cases in time, place and person

Conclusion

Specific public health intervention measures undertaken

Is source of the outbreak determined?

Is mode of transmission established?

Case management

Control measures

Outcome (CFR)

Recommendations

Feedback given or not

What recommendations were proposed?

Were they implemented?

Written feedback

Post- outbreak review

Quality Assessment of Outbreaks reported by all States in 2011 (till 26 June) using 3 Essential Criteria

Essential criteria % of response to disease specific outbreaks

(n=699)

Investigation within 48 hours of first case information • 510 (73%)

Adequate samples sent for lab investigation within 4 days

• In 302 (43%) outbreaks, appropriate human samples sent for lab investigation

• 88 (13%) outbreaks etiologically confirmed

Availability of final outbreak report • 5 %

Quality Assessment of Outbreaks reported by 9 WB funded States in 2011 (till 26 June) using 3 Essential Criteria

Essential criteria % of response to disease specific outbreaks

(n= 516)

Investigation within 48 hours of first case information • 385 (75 %)

Adequate samples sent for lab investigation within 4 days

• In 242 (47 %) outbreaks, appropriate human samples sent for lab investigation

• 66 (13 %) outbreaks etiologically confirmed

Availability of final outbreak report • 4 %

Improving Outbreak detection and reporting

1.

2.

3.

Early detection and response to outbreaks by identifying

EWS from routine analysis of surveillance (S,P,L) data at

DSU/CHC/PHC levels (by identifying any unusual rise in no. of cases)

Ensure 100% reporting of EWS/outbreaks by all

States/Districts (even “NIL” reporting is mandated)

• every week

• on time in the prescribed format

Avoid incomplete/incorrect data entry in the EWS format

Date of start & reporting of outbreak to be mentioned for all outbreaks

“Population affected” is the “Population at risk”

Improving the quality of outbreak investigations, reporting and response

1.

2.

3.

4.

Lab confirmation of diagnosis needs appropriate clinical (human) samples to be sent for lab tests

Identification and Training of Epidemiologists,

Microbiologists, Entomologists and RRT members at

DSU / SSU levels

Existence of a written case management protocol for any epidemic should be made available by the State at each PHC/CHC/District level

Competency assessment tool to be utilized for improving the quality of outbreak investigations and reporting (by the Epidemiologists and Surveillance

Officers)
