Implementation and Feasibility of ‘Screening by Accredited Social Health Activist and diagnosis by Community Health Officers of Asthma and COPD at the primary health care System: A Novel strategy- SHVASAN’

Background

Given the substantial disease burden and Disability-Adjusted Life Years (DALYs) attributed to common chronic respiratory diseases, COPD and Asthma (CRDs) in India, there is an imperative to prioritize early intervention. Prompt attention to CRDs can mitigate the progression to advanced morbidity, avert premature recourse to tertiary care, and reduce economic losses due to decreased productivity and high out-of-pocket health expenditures. Early detection is contingent upon effective screening and diagnosis mechanisms. Despite the fact that CRDs predominantly affect individuals over the age of 40, current service delivery is inadequate: access to diagnostic tools such as spirometry remains largely limited to tertiary care facilities, both public and private. Furthermore, the use of spirometry is constrained by challenges related to technical training, participant cooperation, and financial barriers. Consequently, many individuals only seek care when symptoms such as a persistent cough and breathlessness become severe and unmanageable.

Rationale

The Peak Expiratory Flow Rate (PEFR) method has demonstrated effectiveness in diagnosing conditions such as COPD and asthma, particularly in resource-limited settings. Therefore, decentralizing screening and diagnostic services to locations more proximate to the patient population emerges as a logical strategy for facilitating early detection. The extant scientific literature provides substantial evidence to support the hypothesis that a structured implementation model integrating community-based screening by Accredited Social Health Activists (ASHAs) using peak flow meters, alongside diagnostic confirmation at Health and Wellness Centres (HWCs) via spirometry can enhance early detection and contribute to the strengthening of primary health care guidelines for COPD and asthma management. Although current CRD guidelines at the primary care level offer a supportive framework for such an intervention, the proposed model is poised to provide greater accessibility compared to existing approaches. With guidelines in place yet a lack of clear implementation strategies at the ground level, the present moment offers a timely and strategic opportunity to rigorously explore the feasibility of this model.

Accordingly, it is justified to undertake a study examining the feasibility, including both facilitators and operational challenges, of implementing such a screening and diagnostic pathway at the primary health care level. This research will generate critical evidence to inform the development of implementation strategies as public health services prepare for broader rollout in the near future. Evidence-based policy recommendations stemming from this work will be pivotal in ensuring high-quality care for CRD screening and diagnosis at the primary health care level, preceding full-scale implementation.

The development and application of a Feasibility Index in this context represents a novel scientific contribution, enabling the quantification of implementation feasibility and potentially informing future innovations in this area, particularly as implementation plans transition from design to practice.

Accordingly, I propose the introduction and real-world testing of a novel comprehensive implementation model, “SHVASAN,” to assess its feasibility through systematic identification of facilitators and operational challenges.
