TB Household Contacts - System Design Document¶

Background and Purpose¶

The TB Household Contacts (TB HH) digital data package was developed in response to an expressed need from countries to rapidly adapt a solution for managing the data originating from the planned/undertaken TB programs activities.The TB HH aggregate metadata package has therefore been designed as an installable solution for countries to update their DHIS2-based HMIS according to the updated version of the Consolidated guidance on tuberculosis data generation and use (the link will be provided upon publication on the WHO website).

Tento dokument TB HH Aggregate System Design poskytuje přehled principů návrhu a globálních technických pokynů používaných k vývoji standardního metadatového balíčku WHO pro monitorování preventivních aktivit pro kontakty v domácnostech s případy indexu TBC. Tento dokument je určen pro použití implementátory DHIS2 na národní a místní úrovni, aby mohli podporovat implementaci a lokalizaci balíčku. Balíček metadat TB HH lze přizpůsobit místním potřebám a národním směrnicím.

Tento dokument je určen k použití implementátory DHIS2 na úrovni země a regionu, aby bylo možné podporovat implementaci a lokalizaci konfiguračního balíčku při dodržení stanovených zásad návrhu.

Určení uživatelé¶

Zamýšlenými uživateli tohoto balíčku jsou:

Clinical and program management users at local level for data entry and monitoring of the identification and adherence activities.

Program managers at district and national levels for the monitoring and performance evaluation of the program.

Přehled návrhu systému¶

Případ použití¶

Modul TB HH sleduje logiku preventivních aktivit proti TB mezi kontakty v domácnosti:

Data flow¶

It is recommended that the TB HH module gets assigned to Organisation Units at the lowest level of the health system feasible for reporting data.

Digital data packages are optimized for Android data collection with the DHIS2 Capture App, free to download on the GooglePlay store.

Struktura programu¶

The data are collected quarterly to allow for the correct follow-up timeframe of the TPT course. The structure of the TB HH modules is very simple:

One quarterly aggregated dataset (TB-HH - Household Contacts) for the identification, screening, and TPT eligibility. The metadata captures a minimum number of data points that meet the current WHO reporting requirements.

One quarterly aggregated dataset (TB-HH - TPT outcomes) for the outcomes out of the HH contacts who started the TPT treatment.

One predefined dashboard (TB5. HH Contacts).The analytics and dashboards included in the package are designed to support the routine analysis and use of TPT data at national and sub-national levels.

Dataset Configuration - Household Contacts¶

NOTE

ALL the data elements are used to build indicators ALL data elements are linked to validation rules The zero value has been set as significant

TB Index Cases¶

Sekce uvádí počet případů indexu, které byly oznámeny v analyzovaném čtvrtletí.

Household Contacts of Index TB Cases¶

The section reports the ICs’ HH contacts who have been identified and screened. Please note that the updated version only disaggregates the data by age groups.

TB Preventive Treatment¶

Tato sekce poskytuje potřebné informace o způsobilosti a zahájení TT.

Dataset Configuration - TPT Outcomes¶

In this updated version, outcomes were segregated from screenings and eligibility reporting to accurately capture cohorts of HH contacts initiating TPT treatment within the same analysis time frame. Following WHO guidance, outcomes can be reported by 6 or 12-month periods. The dataset now aligns with reporting outcomes within 12 months after the identification of HH contacts (three quarters earlier).

Cohort of household contacts identified and started on TPT¶

The section reports the cohort of the HH contacts for which the dataset is reporting the outcomes. In this case, users should be reporting the cases who started the TPT treatment out of those identified 3 quarters ago.

TPT outcomes for Household Contacts¶

The section clearly outlines the criteria for the inclusion in the period of reporting.

• Identified 3 quarters ago: Refers to household contacts that were identified or registered in the system three quarters (or nine months) prior to the current time frame or reporting period.
• Started on TPT: This subset comprises those identified household contacts who began TPT within the aforementioned three-quarter period.
• Received an outcome within 12 months after the start of the period when they were identified: This specifies that among the identified household contacts who initiated TPT, the dataset focuses on those who have had an outcome recorded within 12 months after their initial identification. This outcome could be related to the completion of treatment, or the discontinuation of the treatment for any reason within this specified time frame.

Pravidla ověření¶

None of the VRs are set to block the data entry. Should any of the numbers not match the logic behind the rules, the description of the broken rule will simply highlight the gap and will nonetheless let the system save the data. The following validation rules have been created in order to ensure the logic and the quality of the collected data:

NOTE

The “TB-HH - Notified ICs vs Identified contacts” rule: In the VERY rare case that it is a low burden rural health facility, should we make an exception if there is 1 index case, with 0 household contacts. In this case the implementer should consider whether the rule would not be logical for the local context.

Analytics and Indicators¶

The indicators are organized in the TB - HH Indicators group. The numerators and denominators are using the abbreviations commonly used in TB programs.

TB Nomenclature¶

	ICs	Kontakty identifikovány	Kontakty prověřeny	Kontakty Vhodné	Kontakty zahájeny
Celkový počet	newinc_con	newinc_con_ident	newinc_con_screen	newinc_con_elig	newinc_con_prevtx
Počet dětí <5 let	x	newinc_con_04_ident	newinc_con_04_screen	newinc_con_04_elig	newinc_con_04_prevtx
Počet lidí žijících s HIV	x	newinc_con_plhiv_ident	newinc_con_plhiv_screen	newinc_con_plhiv_elig	newinc_con_plhiv_prevtx

Data Triangulation¶

In order to ensure consistency across programs and data, the TB-HH - TB index cases identified indicator can be checked against the TB - Notified TB cases (all cases, all forms) indicator belonging to the TB case notification dataset based on the “Definitions and reporting framework for tuberculosis – 2013 revision” document. The dataset is part of the TB Aggregate System Design.

To lze samozřejmě provést pouze v případě, že jsou ve stejné instanci staženy a použity jiné datové sady patřící do balíčku TB General.

Android Compatibility¶

Digital data packages are optimized for Android data collection with the DHIS2 Capture App, free to download on the GooglePlay store. Key considerations in design was to ensure that all forms are configured with sections that structure form layout for better display on the android devices. Also, with the requirement of minimal data disaggregation in this package, all the dataSet layout should provide a concise view for Android display.
