AIIMS Delhi’s National Mental Health Survey-2 is examining how the city’s mental-health burden and access to care have changed over nine years, including how many people need treatment, how many receive it and how many remain outside the health system. The exercise matters not only as a health study but also as an assessment of how an urban service network responds to a largely invisible demand.
The survey is being conducted by AIIMS’s Centre for Community Medicine. According to Professor Harshal Ramesh Salve, its purpose includes measuring the prevalence of mental illness, assessing the treatment gap, examining the use of health services, documenting disability and reviewing the existing mental-health system. The findings are expected to provide a new picture of Delhi’s mental-health situation after the previous national survey conducted nine years ago.
That time gap gives the exercise its central importance. A prevalence estimate on its own can indicate how widespread mental-health conditions are, but it cannot show whether the city’s institutions have expanded services at the same pace, whether people are reaching care earlier or whether treatment remains inaccessible to large sections of the population. By combining disease prevalence with service use and system capacity, the survey is designed to connect the scale of need with the functioning of care delivery.
The source material does not provide the results of the new survey. It therefore cannot establish whether Delhi’s mental-health burden has increased, declined or remained stable. What it does establish is that AIIMS is collecting evidence on several dimensions of the problem, including treatment needs and the number of affected people who are not using formal health services. The eventual value of the exercise will depend on how these findings are reported and translated into planning decisions.
## The urban significance of a mental-health survey
Mental-health care is often discussed through individual experiences, but access to treatment is also shaped by the structure of a city’s public-health system. Residents need nearby facilities, trained personnel, essential medicines, referral pathways and information about where to seek help. They also need services that can respond to different age groups and levels of need. A survey that measures these conditions alongside illness prevalence can reveal whether the city’s service network is functioning as a connected system or as a collection of unevenly available facilities.
AIIMS is also assessing the mental-health system itself. A workshop held on 18 September brought together experts, health workers, government and institutional representatives and social organisations. The review covered human resources, infrastructure, availability of essential medicines, training, public awareness and coordination between departments.
These areas point to the administrative dimensions of mental-health care. A shortage of professionals is not addressed in the same way as a shortage of medicines. Weak public awareness creates a different barrier from poor coordination between departments. Similarly, infrastructure can exist on paper while remaining difficult to access if referral arrangements, staffing or follow-up care are inadequate. The workshop’s scope suggests that the assessment is looking beyond the number of facilities to the conditions that determine whether those facilities can provide usable care.
The inclusion of different institutions and social organisations is also significant. Mental-health services operate across multiple layers of the system, and people may encounter hospitals, primary-care facilities, community workers, educational institutions and social organisations at different points. The supplied report does not describe the exact administrative structure or recommendations emerging from the workshop, but its participant mix indicates that the assessment is intended to examine coordination as well as individual service components.
## Adults and adolescents in one city-wide picture
The national survey is assessing the mental-health status of adults aged above 18 as well as adolescents between 13 and 17. This widens the frame beyond adult treatment demand. It also recognises that mental-health needs may emerge across different stages of life and may require different points of contact with public services.
For adolescents, access and identification can involve institutions beyond hospitals. The source material does not specify the survey’s school or community methodology, so no conclusion can be drawn about how young people will be reached or how their findings will be separated by location or social group. However, the inclusion of the 13-to-17 age group means that the eventual results could show whether the city’s mental-health planning is equipped to identify needs before they become more difficult to treat.
For adults, the survey’s focus on treatment use and unmet need is equally important. The presence of a mental-health condition does not automatically translate into contact with a formal provider. Cost, distance, awareness, stigma, availability of specialists and the design of referral systems can all influence whether care is sought, although the supplied report does not quantify the contribution of any of these factors in Delhi.
The survey is therefore positioned to answer a series of linked questions rather than one headline question. How widespread are mental-health conditions? How many people require treatment? How many are receiving it? What proportion is outside the health system? And does the available system have the staff, infrastructure, medicines and training required to respond? The source confirms that these subjects are being examined, but it does not yet provide the numerical answers.
## What the evidence can and cannot show
The previous national mental-health survey provides the baseline for the nine-year comparison, but the report supplied for this story does not include its Delhi figures. It also does not state the sample size, survey locations, fieldwork period, methodology or the indicators that will be used to compare the two rounds. These details will be necessary before readers can assess the strength and limits of any change reported by AIIMS.
That limitation is important because a change in measured prevalence can reflect several factors, including genuine changes in mental-health conditions, differences in awareness, variations in reporting behaviour or changes in survey methods. The supplied material does not indicate whether the second survey uses an identical design to the first. It is therefore too early to interpret the nine-year comparison as a direct measure of improvement or deterioration.
The system assessment may provide a second layer of evidence. Human resources, infrastructure, essential medicines, training, awareness and inter-departmental coordination are all practical conditions of service delivery. Yet a review of these components will need to be connected to service-use data to show where the most consequential gaps lie. A facility count, for example, would not by itself establish that care is accessible or continuous.
The report also does not identify the survey’s expected publication date or explain how its findings will be incorporated into Delhi’s health planning. Those next steps will determine whether the survey functions only as a description of the problem or becomes a planning instrument for improving services.
## The larger governance question
Delhi’s mental-health challenge is being examined through a city-level lens, but the response depends on institutions that may have different responsibilities, resources and operating procedures. The workshop’s emphasis on coordination indicates that the survey is looking at this institutional interface. If different parts of the system do not share information or referral responsibility, residents can remain without care even when individual services are available.
The same applies to treatment gaps. Measuring how many people need care but are not receiving it is essential, but the policy response will require a clearer account of where people are lost: before seeking help, at the first point of contact, during referral, because of medicine shortages or after treatment begins. The supplied material does not yet identify these specific failure points. The survey’s findings may help distinguish them.
For urban policymakers, the significance of the exercise lies in this connection between population need and institutional capacity. Delhi’s mental-health system cannot be understood only through the number of people affected or only through the number of facilities available. The relevant question is whether the system can provide timely, affordable and continuous care to the groups identified by the survey.
AIIMS’s National Mental Health Survey-2 has not yet supplied that final answer. At this stage, it has established the scope of the investigation: adults and adolescents, prevalence, treatment needs, service use, disability and the capacity of the existing system. The key developments to monitor are the release of the survey findings, the Delhi-specific comparison with the earlier assessment and any formal response on staffing, infrastructure, medicines, training and coordination.
