ACF campaign activities
ContentActive Case Finding (ACF) is a provider-initiated activity with the primary objective of detecting TB cases early by active case finding in targeted groups and to initiate treatment promptly.
- It can target people who anyway would have sought health care with or without symptoms or signs of TB and also people who do not seek care.
- Increased coverage can be achieved by focusing on clinically, socially and occupationally vulnerable populations.
- ACF activities in a campaign mode will create mass awareness about the signs and symptoms in general population
Objective of ACF campaign activities- Reaching the unreached in a campaign mode to enhance TB case finding

Figure 1: Objectives of active case finding
Beyond TB disease, screening can also identify individuals who are eligible for and would benefit from TB preventive treatment (TPT) once TB disease is ruled out, thus further averting future incident TB.
General process is as below:

Mapping the population for ACF
ContentMapping of vulnerable population is a pre-requisite for conducting an efficient ACF campaign. It involves understanding the population characteristics, identifying and enumerating and mapping the target population.
Guidelines for mapping
- Identify & map high risk/ vulnerable populations in the local area with the following guidance. If additional information is available locally, it can be used for the prioritisation of target groups.
Priority Urban area Rural area Tribal area
1 Slum Difficult to reach villages Difficult to reach villages & hamlets 2 Prisons inmates Mineworkers Villages with a known higher caseload 3 Old Age homes Stone crusher workers Tribal school hostels 4 Construction site workers Populations groups with known high malnutrition Areas with known high malnutrition 5 Refugee camps Populations known to drink raw milk Villages seeking care from traditional healers 6 Night shelters Populations known to eat uncooked meat Populations known to drink raw milk 7 NACO/SACS identified HRG for HIV NACO/ SACS identified HRG for HIV Populations known to eat uncooked meat 8 Homeless Weaving & Glass industrial workers Tribal areas with little ventilated huts 9 Street children Cotton mill workers 10 Orphanages Unorganised labour 11 Homes for destitute Tea garden workers 12 Asylums Villages largely seeking care from traditional healers

Yes Yes Microplanning and execution of ACF campaign
ContentMicroplanning for ACF Campaign
A microplan is a detailed plan of action in terms of human resources, materials, money and time. A good microplan ensures that the health intervention reaches each individual beneficiary and is crucial to the success of the activity. For Active Case Finding (ACF), microplanning is performed at the health facility level and collated at the block, district and state levels. Training for the same is given to concerned personnel during state, district and block level meetings prior to the campaign. Microplan at PHI, Block, District and State levels should be ready at least 15 days prior to the initiation of field activities.
Microplanning is done with respect to:
I. Advocacy, Communication and Social Mobilization (ACSM)
A comprehensive IEC plan should be made with communication material for mass media, mid-media and print media to reach out up to the remotest village in advance.
II. Logistics
- Microplan should include planning additional consumables required for the campaign
- It includes additional slides, laboratory reagents, sputum cups, falcon tubes, sample transport boxes, X-ray films, Cartridge-based Nucleic Acid Amplification Test (CBNAAT) cartridges, etc. Additional sputum containers (minimum 1000 per lakh population) will be procured and supplied to health staff for collecting sputum sample from the eligible symptomatic two weeks before the start of field activities
- Linkages of Peripheral Health Institute (PHI) areas with Designated Microscopy Centre (DMC), X-ray facilities, CBNAAT lab, Extra Pulmonary (EP) sample collection and EP testing should be included in the planning up-front.
- Laboratory technicians of the linked DMC and CBNAAT labs should be well informed about the increase in workload and recording of information during ACF activities.
III. Field activities including human resources
- Maps prepared for other campaigns like Pulse Polio, Leprosy Case Detection Campaign (LCDC), etc. must be used while planning. If maps are not available with local bodies, search team members and supervisors should be sent to the area before the ACF campaign, in order to become familiar with the area and develop maps.
- The number of houses to be covered each day should be mentioned in the microplan. This number may vary from day to day depending upon the geographical situation of the area planned to be covered by the team on a particular day.
- Teams of two persons each should go house-to-house. Out of the two members in each team, one should be a local volunteer (including Accredited Social Health Activist (ASHA)).
- Each team should be allocated clear-cut, well-demarcated areas clearly mentioning the starting and ending points, identifiable with landmarks; for each day of House to House (h-t-h) activity.
- In special areas, one additional person from the local community, where the team will be working, should accompany the team.
- Human resources required for covering the mapped vulnerable population during field activities should be calculated and recorded.
- For planning and implementation purposes, urban areas should be divided into smaller planning units based on municipal wards or assemblies, or by roads or prominent landmarks. Each such unit should be put under the charge of a medical officer or nodal officer.
- Involvement of the local community, leaders, health officials, municipal bodies and their staff is essential in planning.
- Local staff is familiar with the layout of the urban areas and their inputs are vital for planning and supervision of house-to-house activities.
Execution of Microplan
The ACF campaign is executed as per the microplan and supervision is done with reference to the microplan
The House to House (h-t-h) survey is done for 2 weeks
A survey team consisting of 2 persons - one NTEP staff/ partner organization staff/ General Health services staff and one local volunteer / ASHA worker. They go from house to house in the mapped vulnerable areas/ key population groups and screen individuals for symptoms of TB. After screening, the eligible population for sputum examination includes: Persistent cough for ≥2 weeks, Fever for ≥2 weeks, Significant weight loss (>5% weight loss over last 3 months), Presence of blood in sputum any time during the last 6 months, Chest pain in the last one month, History of Anti-TB Treatment (previous/ current). If any one of these is present, a sputum cup or falcon tube is given to them and a sputum sample is collected. Sputum samples thus collected are transported to a designated lab using the sample transport system existing in the area. testing using smear microscopy/CBNAAT will be done for all symptomatic persons as per the state policy. Those who are microbiologically confirmed to be positive should be initiated on treatment within 2 days. Additionally, the team will look for other symptoms/diseases also. If person is having any symptoms or other ill health, s/he will be referred for evaluation by a Medical Officer for further management, if needed. Field Activity Report will be submitted by each health staff on a daily basis to the Medical Officer of the Peripheral Health Institution

Recording formats under ACF campaign
ContentVulnerability mapping and Microplanning are 2 important activities of Active Case Finding which precede field activities. Vulnerable populations should be mapped and recorded in prescribed formats from health facility level onwards. Mapping data from PHI are consolidated at Block level, those at Block level are consolidated at district level and those at district level are consolidated at state level. Data from mapping formats is used for microplanning. Microplanning forms the basis of field activities. Microplans are also consolidated at subsequent levels. During supervision and monitoring, it is important to assess the activities with respect to the microplan.
The recording formats for ACF include:
1. Formats for mapping - Health Facility Level, Block Level, District Level and State Level
2. Formats for microplanning - Manpower, Logistics, Field Activity
FORMATS FOR MAPPING
Mapping details should also be entered in Ni-kshay under the section shown below:

Fig: Ni-kshay section for reporting various ACF activities
FORMATS FOR MICROPLANNING
Based on the requirement obtained from the mapping exercise, microplanning is done with respect to human resource, logistics and field activities
Human Resource Planning Form
Field activities are captured in Form 1 & 2 of the ACF. The data from field activities are compiled at the PHI level and submitted to the District and State using google sheets at present. Although there is no specific mechanism to demarcate the presumptive TB patients and the confirmed (clinical and microbiological) TB cases in Ni-kshay, States follow different mechanism including marking in the Laboratory register as ACF testing and sending a separate sheet to the district in paper format.
