                                What is Indoor Air Quality and Why is it Important to Preserve it?

                                Indoor Air Quality or IAQ refers to the air conditions within and around a building or structure that can affect the health and comfort of the occupants. 

                                With people spending almost 90% of their time indoors, maintaining IAQ becomes essential to mitigate adverse health impacts. 

                                As medical practitioners, para-medical staff, and patients spend long hours on the premises, they are more vulnerable to healthcare-associated infections. Unhealthy IAQ affects the staff’s productivity and the patient’s ability to heal. 

                                Since most of the occupants in a healthcare facility are patients, they are more likely to have compromised immune systems. This makes them even more vulnerable to various airborne infections. In such an environment, having robust IAQ monitoring and management becomes extremely significant. 

                                What are the Causes of Poor Indoor Air Quality in Healthcare Institutions?

                                Numerous sources can deteriorate the air quality within healthcare institutions, some of which are: 

                                • Old and outdated equipment, such as ventilators and HVAC systems. This results in poor air circulation and can introduce contaminated outdoor air.  
                                • Ongoing renovation projects within the premises can ruin the air quality as they can introduce dust particles and fungal spores. 
                                • Chemical particles are released from volatile organic compounds (VOC), disinfectants, chemicals stored in laboratories, and sterilizing substances. 
                                • Airborne bacteria, viruses, and mold can adversely impact air conditions. 
                                • Moisture and mold formation can also contaminate the air quality. 

                                Health Hazards due to Inadequate Indoor Air Quality

                                Though these facilities are cleaned and sterilized frequently, medical centers and laboratories are the biggest sources of pathogenic bacteria leading to hospital-acquired infections. 

                                According to the Centers for Disease Control and Prevention (CDC), around 98,000 people die due to hospital-acquired infections. Most of these infections and deaths have been attributed to bad indoor air quality. 

                                Apart from HAI (hospital-acquired infections), poor IAQ would cause health issues such as headaches, fatigue, and irritation of the eyes among healthcare professionals. 

                                Here are some of the common health problems that might affect professionals: 

                                • Respiratory illnesses such as asthma and allergic reactions 
                                • Complications related to lungs 
                                • Aggravated heart conditions
                                • Coughing
                                • Carbon monoxide poisoning
                                • Cancer
                                • Skin illnesses scratchy

                                Like other environmental health parameters, IAQ requires regular monitoring to determine the potential risks and to keep indoor air contamination in check. 

                                However, monitoring air quality parameters is complex and challenging. Let us see how below-par IAQ can affect the patient’s health, staff’s productivity, and medical equipment:

                                Increased Health Risks for Patients, Staff, and Visitors

                                The COVID-19 pandemic taught us the importance of maintaining and regulating IAQ to limit the spread of infections.  Inferior IAQ in healthcare facilities is a major contributor to hospital-acquired infections and presents serious hazards to the physical well-being of patients and staff.

                                Hospitals are closed spaces, hence fall in high-risk areas. This makes it very important to maintain proper IAQ to lower the health risks for staff members and patients. 

                                Challenges of unhealthy indoor air quality

                                Several studies have shown that an average of 10% of hospital-acquired infections are spread through airborne transmission due to unhealthy IAQ. 

                                Apart from hospital-acquired infections, extended exposure to substandard IAQ can lead to chronic health conditions such as allergic reactions or aggravated asthmatic episodes. 

                                Affects the Quality of Medicines, Vaccines, and Surgical Equipment 

                                Inappropriate temperature and humidity play a part in degenerating the IAQ. It can trigger various bacterial, fungal, and viral infections and pose serious health implications. 

                                Besides, high humidity can deteriorate the surgical equipment, medicines, and chemicals stored in the laboratories. 

                                Many sensitive medicines and surgical devices require protection against toxic gases. Long exposures cause corrosion and micro-corrosion-related damages. 

                                Moreover, hospitals have a large inventory of some temperature-sensitive drugs and vaccines. Storing medicines/vaccines in a clean and dry environment becomes crucial to prevent them from going bad. 

                                IAQ for Regulatory Compliance 

                                Right from bacterial growth to the potential leakage of bio radiation, hospitals or laboratories are susceptible to indoor air contamination. Therefore, preserving IAQ in a healthcare unit becomes the utmost priority. To address this, several agencies have issued regulatory compliance for monitoring IAQ. 

                                When a healthcare unit or laboratories have inadequate indoor air monitoring and management solutions, they fail to comply with these regulatory bodies. 

                                Such non-compliance can attract heavy fines and even legal suits (in case of any hospital-acquired infection-related deaths or complications). This creates a huge burden on the finances and thus extends cost overheads. 

                                Potential Outbreak of Diseases and Infections

                                Bad indoor air quality provides a breeding ground for various harmful bacteria and viruses to thrive. Not monitoring air quality can increase the potential risk of disease outbreaks. 

                                According to a report published in The Mirror, around 14,000 people died after contracting hospital-acquired airborne COVID infection.  

                                Such incidences make it absolutely necessary to install a smart air quality monitoring system to maintain IAQ and prevent disease outbreaks. 

                                Negatively Impacts Staff Productivity 

                                Hospital air quality isn’t just about posing health hazards; it can have an adverse impact on staff productivity. 

                                Various studies have shown that improved indoor air quality can significantly reduce the chances of acute respiratory illnesses.  With lesser cases of AIRs and other diseases, the incidences of absenteeism decrease considerably.  

                                Moreover, better indoor air quality improves the mental alertness of the staff, making them more productive.
