NEW DELHI, November 14: The Delhi government has directed all government run hospitals in the national capital to establish dedicated chest clinics to address the growing number of patients suffering from respiratory and cardiovascular problems associated with air pollution.
The initiative is aimed at strengthening the public healthcare response during the months when pollution levels generally deteriorate, particularly between September and February. Hospitals have been instructed to make the facilities operational within seven days of the November 6 order issued by the Directorate General of Health Services (DGHS).
The decision comes as Delhi continues to experience deteriorating air quality during the winter season, raising concerns about the impact of polluted air on people with existing medical conditions and those exposed to hazardous environmental conditions for extended periods.
The dedicated clinics are expected to provide specialised screening, diagnosis and treatment for patients experiencing respiratory and cardiopulmonary complications aggravated by pollution. The arrangement will also help hospitals monitor the pattern of pollution-related illnesses and improve the organisation of medical services during periods of poor air quality.
Under the new directions, the clinics will operate daily throughout the September-February period every year. This arrangement is intended to ensure that patients can access dedicated medical services during the months when respiratory complaints generally increase.
The government has asked hospitals to make adequate arrangements for doctors, healthcare workers, diagnostic equipment and medicines. They must also establish appropriate systems for identifying patients, recording diagnoses and reporting information about pollution-related illnesses.
Each government hospital will be required to appoint a nodal officer responsible for supervising the functioning of its chest clinic and coordinating with the relevant health authorities.
Hospitals must also submit information about the location of the facility, operating hours, staff deployment and details of the designated officer to the State Programme Officer under the National Programme on Climate Change and Human Health (NPCCHH).
In addition, the order requires hospitals to submit daily facility-level reports to their respective district nodal officers by 5 pm. The reporting mechanism is expected to help authorities assess the number of patients accessing the facilities and monitor the implementation of the initiative.
The directive follows guidelines issued by the National Centre for Disease Control (NCDC), which have emphasised the need for dedicated facilities to improve the screening, management and monitoring of health conditions associated with air pollution.
Focus on vulnerable population
Children, elderly people and individuals suffering from pre-existing respiratory or cardiovascular conditions are among those considered particularly vulnerable to polluted air.
Exposure to particulate matter and other harmful pollutants can aggravate asthma, chronic obstructive pulmonary disease (COPD), bronchitis and other respiratory conditions. It can also increase the risk of cardiovascular complications, particularly among individuals who already have underlying health problems.
Fine particulate matter, especially PM2.5, is a major public health concern because its extremely small particles can penetrate deep into the respiratory system. Some particles can enter the bloodstream, contributing to inflammation and other health complications.
People exposed to polluted air may experience coughing, throat irritation, breathing difficulties, wheezing, chest discomfort and worsening of existing respiratory symptoms.
However, the effects are not limited to people who already have diagnosed illnesses. Prolonged exposure can also affect otherwise healthy individuals, particularly those who spend considerable time outdoors or work in environments with high pollution levels.
The establishment of specialised clinics is expected to help hospitals identify patients who require medical attention and provide appropriate treatment based on their symptoms and clinical condition.
For children, early assessment is particularly important because respiratory problems can interfere with normal activities, sleep and school attendance. Elderly patients may also require closer monitoring because age-related changes and existing medical conditions can make them more susceptible to complications.
Patients suffering from asthma or other chronic respiratory illnesses may need regular consultations and adjustments to their prescribed treatment during periods of severe pollution.
The clinics could provide a more organised point of access for such patients instead of requiring them to navigate general outpatient departments during the winter rush.
Separate facilities expected to improve patient management
Until now, people experiencing pollution-related health problems have generally approached regular outpatient departments or emergency services at government hospitals.
The dedicated chest clinics are expected to create a more focused system for examining patients whose symptoms are associated with poor air quality.
The separation of these services could help medical staff identify respiratory complaints more efficiently, maintain better records and understand how pollution affects different population groups.
It may also help health authorities identify periods when patient numbers increase and determine whether additional medical resources are required.
The initiative is particularly significant for large government hospitals, where doctors regularly manage patients with multiple health conditions and high outpatient volumes.
A dedicated arrangement could improve coordination between respiratory medicine specialists, general physicians, diagnostic departments and other healthcare professionals.
However, the effectiveness of the programme will depend on the availability of trained medical personnel, essential medicines and functioning diagnostic facilities.
Hospitals will also need to ensure that patients are informed about the clinics and understand how to access them.
Monitoring and reporting to strengthen the response
The reporting requirements form an important part of the government’s new approach.
By collecting daily information from hospitals, district authorities can obtain a clearer picture of the number of people seeking treatment for pollution-related conditions.
Such information may help identify areas experiencing a higher burden of respiratory illness and assist officials in planning healthcare resources.
The appointment of nodal officers is also intended to establish clear responsibility for implementation.
Each officer will supervise the clinic’s operations, ensure that necessary arrangements are available and coordinate the submission of information to the designated authorities.
The requirement to provide daily reports by 5 pm could also help the health department identify operational gaps and assess whether hospitals are following the prescribed directions.
The National Programme on Climate Change and Human Health provides the broader framework for addressing the health consequences of environmental and climate-related factors.
The NCDC has developed operational guidelines and reporting formats for air pollution-related chest clinics, including patient-level and facility-level information.
These measures are intended to improve the quality of public health surveillance and support evidence-based decisions.
Air pollution remains a major health challenge
Delhi’s recurring winter pollution problem has become a major public health concern, with emissions from vehicles, industrial activities, construction, road dust, waste burning and seasonal agricultural fires contributing to poor air quality.
Weather conditions also influence pollution levels. During winter, low temperatures, reduced wind speeds and atmospheric conditions can restrict the dispersal of pollutants, allowing harmful particles to accumulate near the ground.
The combination of these factors can lead to prolonged periods of unhealthy air quality.
For residents, exposure may occur during daily commuting, outdoor employment, school activities and other routine activities.
People living close to major roads, industrial areas and construction sites may face additional exposure depending on local conditions.
The health consequences can extend beyond the immediate winter period. Repeated or long-term exposure to air pollution has been associated with chronic respiratory diseases, cardiovascular problems and other serious health outcomes.
This makes the availability of specialised medical services important, particularly in a city where poor air quality returns regularly.
Public health experts have repeatedly stressed that medical treatment alone cannot resolve the wider problem. Reducing emissions and limiting exposure remain essential components of a comprehensive response.
Measures such as improving public transportation, controlling industrial emissions, preventing open waste burning, managing construction dust and strengthening clean-energy use are important for reducing pollution at its source.
Prevention and public awareness remain important
Alongside the new hospital facilities, public awareness will be necessary to reduce the health impact of polluted air.
Residents should pay attention to official air-quality advisories and follow medical advice when pollution levels become unhealthy.
People with existing respiratory or cardiovascular conditions should continue their prescribed treatment and consult healthcare professionals if symptoms worsen.
Children, older people and patients with chronic illnesses may need to limit strenuous outdoor activities during periods of severe pollution.
Individuals experiencing serious breathing difficulties, persistent chest pain or other alarming symptoms should seek prompt medical assessment rather than relying on home remedies.
Hospitals will also need to communicate the availability of the new facilities so that residents know where to obtain appropriate care.
The dedicated chest clinics represent an effort to strengthen Delhi’s healthcare infrastructure against a recurring environmental challenge. Their long-term value will depend on whether hospitals can maintain adequate staffing, medicines, diagnostic capacity and reliable reporting throughout the pollution season.
The government has sought to establish a more structured system for identifying and treating pollution-related illnesses rather than depending entirely on general outpatient and emergency services.
As Delhi enters another difficult winter, the implementation of these clinics will be closely watched by healthcare professionals and residents alike. The initiative could improve access to respiratory care, but lasting improvements in public health will also require sustained action to reduce the sources of air pollution.
