Thoughtful technology solutions for real-time disease surveillance – ET HealthWorld

Thoughtful technology solutions for real-time disease surveillanceby Akhil Malhotra

Disease surveillance — assortment, evaluation and interpretation of disease-related information — is vital to public well being. Depending on the disease being tracked, its influence and infectiousness, public well being departments repeatedly accumulate data similar to demographics, signs, publicity, contact historical past, progress made, care obtained and different epidemiological traits. This data is then used to design acceptable interventions and implement them at scale.

A strategic mixture of lively, passive and sentinel surveillance are the spine of the well being data system of any nation. The ongoing pandemic has proven how correct and real-time disease surveillance can act as early warning programs and play a foundational function in stopping transmission and administering well timed care.

However, whereas each governments and leaders perceive the significance of disease surveillance, the implementation of it leaves a lot to be desired.

To start with, a lot of the disease surveillance right now in India depends closely on human sources, carried out by Accredited Social Health Activists (ASHA). ASHA staff bear an amazing quantity of the workload. To get an concept, we solely want to have a look at the 24 registers or logbooks for numerous packages, along with the sector visits and citizen interplay they do repeatedly.

This clerical and administrative workload leaves room for errors like unreported/missed incidents, delayed reporting and even information manipulation. For occasion, Kumar et.al. in 2014 discovered that 93% of staff on the well being facilities weren’t conscious of the idea and the apply of zero reporting — the method of recording the absence of circumstances below surveillance to make sure that they haven’t merely forgotten to report. The researchers additionally discovered that not one of the facilities they surveyed was training zero reporting.

Moreover, this system-primarily based strategy to surveillance creates vertical silos, exacerbating the workload. For instance, the National TB Elimination Program and National AIDS Control Program run in parallel. There is little doubt that each the packages are mandatory and have demonstrated their worth in lowering disease transmission. However, each these packages command particular person infrastructure to operate, despite the fact that sufferers tracked largely overlap since HIV-constructive sufferers are extra inclined to TB.

In addition, there are manner too many organizations concerned in surveillance such because the Indian Council of Medical Research’s (ICMR) Virus Research and Diagnostic Laboratory (VRDL) Network, the National Vector Borne Disease Control Programme (NVBDCP) and the Integrated Disease Surveillance Programme (IDSP). All three of those organizations accumulate related information however would not have a mechanism of information sharing.

These challenges might be successfully addressed with technology solutions that sustainably assist lively, passive and sentinel surveillance.

Active surveillance requires the officers/group well being staff (CHWs) to actively search for data. It is a useful resource-intensive exercise and often entails discipline visits. Applications like DHIS2, CommCare, Avni have made a major influence by lowering the work concerned in information assortment and reporting.

These purposes might be run on cell phones and tablets. Health staff can carry these apps to the sector and accumulate information on the go. These apps can accumulate and save information even in areas with no connectivity and sync seamlessly when the connectivity is resumed. This cuts down the lag in reporting in addition to the margin of human error.

Passive surveillance requires well being professionals to report back to the authorities once they encounter sufferers with signs associated to the 34 notifiable ailments, 12 L-type and 22 P-type ailments. Electronic well being data (EHRs) might be the spine of such a passive surveillance system.

With the roll-out of the National Digital Health Mission (NDHM), EHR adoption is more likely to improve, with extra well being services taking part as nodes for sentinel surveillance. Linking it with Geographic Information System (GIS) and visualization programs will allow the researchers and choice-makers to establish correlations that aren’t obvious in tabular codecs.

As the pandemic continues and nationwide-stage public well being initiatives turn into extra crucial, technology solutions are elementary to constructing strong disease surveillance. Various digital well being purposes amassing information for particular functions can come collectively to supply clear and real-time visibility into the general public well being posture of a rustic.

With the National Digital Health Mission rolling out quickly in India, we’ve a major alternative to develop a complete and unified system for lively, passive and sentinel surveillance that may be leveraged by the federal government to construct a greater-knowledgeable and responsive public well being system.
