Healthcare in India has changed dramatically over the last two decades.
Hospitals today are more advanced, medical equipment is more sophisticated, patients are more informed, and healthcare professionals are working with increasingly complex clinical systems. But alongside these visible changes, another transformation has been taking place quietly—the growing focus on quality, patient safety, standardisation and continuous improvement.
One organisation has played a particularly important role in this journey: the National Accreditation Board for Hospitals & Healthcare Providers (NABH), a constituent board of the Quality Council of India.
NABH began its journey in 2005 with the objective of establishing a structured accreditation system for healthcare organisations in India. Accreditation of healthcare organisations began in 2006.
Since then, NABH standards have continued to evolve with the healthcare sector.
The journey from the early standards to the NABH 6th Edition, released in January 2025, tells an important story—not simply about accreditation, but about how Indian hospitals are gradually moving from basic compliance towards a culture of continuous improvement.
From compliance to continuous improvement
When the early NABH standards were introduced, they brought much-needed structure to Indian hospitals.
Areas such as patient care, infection control, medication management, patient rights, documentation, facility management and safety began to be addressed through defined systems and processes.
That was an important first step.
But healthcare never stands still.
New technologies are introduced. Medical equipment becomes more sophisticated. Hospitals become larger and more complex. New risks emerge. Patient expectations change. Regulations and safety requirements evolve.
Therefore, hospital quality standards also need to evolve.
This is one of the most important aspects of the NABH journey.
Over the years, the emphasis has increasingly moved beyond simply having policies and procedures. Hospitals are expected to demonstrate that systems are actually implemented, monitored, measured and improved.
The current NABH Hospital Accreditation Programme focuses on quality and patient safety across clinical as well as administrative and infrastructure-related functions. NABH describes the accreditation framework as a structured approach to quality improvement, patient safety and continuous learning.
In other words:
Having a system is important. Making sure that the system works when it matters is even more important.
NABH 6th Edition: A broader approach to hospital quality
The NABH Hospital Accreditation Standards 6th Edition represents another step in this evolution.
The edition retains the familiar ten-chapter structure while introducing 639 Objective Elements, classified under Core, Commitment, Achievement and Excellence levels. The framework places greater emphasis on areas such as patient-centred care, outcomes, risk management, technology, clinical audit, quality improvement, healthcare-worker wellbeing and sustainability.
This is significant because modern hospital quality cannot be measured only by looking at clinical outcomes.
A hospital’s physical infrastructure also has a direct impact on patient safety.
Consider an operating theatre.
The clinical team may be highly skilled. The surgical equipment may be state-of-the-art. The hospital may have excellent infection-control systems.
But what happens if the electrical supply suddenly fails?
What happens if a poorly maintained electrical panel overheats?
What happens if an earthing system is inadequate?
What happens if a protective device fails to operate during a fault?
These are not merely engineering questions.
They can become patient-safety questions.
Why hospital electrical safety is part of patient safety
This is where the connection between NABH standards and hospital electrical safety audits becomes particularly important.
Hospitals depend on electricity for almost every critical activity.
Operating theatres, ICUs, NICUs, cath labs, diagnostic imaging, laboratories, medical gas systems, ventilation, lifts, water pumping systems, IT infrastructure, communication systems and emergency systems all depend on reliable electrical infrastructure.
An electrical failure can therefore have consequences far beyond equipment damage.
It can interrupt critical patient care.
It can damage expensive medical equipment.
It can create fire and electrical shock hazards.
It can affect emergency services.
It can compromise the continuity of healthcare operations.
The NABH 6th Edition explicitly includes electrical safety audits within its Facility Management & Safety requirements. Under FMS.3, the standard states that the organisation conducts electrical safety audits for the facility.
This is an important reminder that hospital electrical safety is not simply a maintenance department responsibility. It is part of the broader hospital safety system.
What our hospital electrical safety audit experience has taught us
At Sustenergy Foundation, our work in hospital electrical safety has given us an opportunity to see this issue from the ground level.
We have worked with hospitals in different parts of India and have supported more than 100 hospitals through electrical safety and energy-related assessments.
Our experience has shown us something very interesting.
A hospital can have excellent doctors, advanced medical equipment and impressive infrastructure—and still have electrical safety gaps that may not be immediately visible.
During electrical safety audits, issues can range from ageing electrical infrastructure and inadequate documentation to overloaded circuits, earthing concerns, protection-system deficiencies, poor housekeeping around electrical panels and gaps in preventive maintenance.
We have also seen hospitals where engineering teams have built excellent systems.
They conduct periodic inspections.
They maintain records.
They monitor electrical parameters.
They act on audit findings.
They carry out preventive maintenance.
Most importantly, they treat electrical safety as an ongoing responsibility rather than an activity performed only before an accreditation assessment.
That difference is extremely important.
Electrical safety is not something a hospital should prepare for only when an auditor arrives.
It should be part of everyday hospital operations.
From electrical maintenance to electrical safety audits
The evolution of NABH requirements also reflects the changing understanding of electrical safety.
Earlier hospital standards addressed areas such as electricity availability, alternate power sources, engineering services, maintenance and facility safety.
The 5th Edition went a step further by specifically requiring organisations to conduct electrical safety audits.
The 6th Edition continues this emphasis within Facility Management & Safety.
This is an important shift in thinking.
An electrical system cannot be considered safe simply because it is operating.
A panel may be energised and functioning today while still having:
- loose electrical connections;
- abnormal temperature rise;
- overloaded circuits;
- inadequate protection;
- poor earthing;
- high earth fault loop impedance;
- defective RCCBs/RCBOs;
- insulation deterioration;
- improper cable termination;
- inadequate segregation;
- poor housekeeping;
- or other hidden electrical risks.
This is why a professional hospital electrical safety audit should go beyond a visual inspection.
It should involve appropriate inspection, testing, measurement, thermal imaging, documentation, risk assessment and corrective-action planning.
The objective is not simply to identify problems.
It is to help the hospital understand which risks matter most, why they matter and what needs to be done about them.
Thermal imaging and condition monitoring
Modern hospital electrical safety audits can also use technology to identify problems that may not be visible during a conventional inspection.
Infrared thermography, for example, can help identify abnormal temperature patterns in electrical panels, busbars, cable terminations, breakers, transformers and other electrical components.
An electrical connection may look perfectly normal from the outside while developing excessive heat because of looseness, overloading, imbalance or deterioration.
Early identification provides the engineering team with an opportunity to investigate and correct the issue before it develops into a major failure.
For critical healthcare facilities, this type of condition monitoring can become an important part of preventive and predictive maintenance.
NABH has changed the conversation
Perhaps NABH’s biggest contribution is not any individual requirement.
It is the change in the way hospitals think about quality.
The conversation is gradually moving from:
“Do we have it?”
to:
“Is it safe?”
“Is it working?”
“Is it being maintained?”
“Has it been tested?”
“Do we have records?”
“What happens if it fails?”
“Have we identified the risk?”
“Has corrective action been completed?”
“Are we actually improving?”
That change in mindset is at the heart of quality improvement.
It also creates greater recognition for hospital engineering teams.
Engineers and facility-management professionals are not simply maintaining buildings and equipment.
They are helping maintain the infrastructure on which patient care depends.
NABH and the role of hospital engineering teams
A hospital’s engineering team often works behind the scenes.
Patients may never see the electrical room, transformer yard, HT panel, UPS room, DG room or central plant.
But these systems support almost everything that happens inside the hospital.
A reliable engineering team therefore plays a critical role in maintaining patient-care continuity.
This includes areas such as:
- HT and LT electrical systems
- Transformers
- LT panels and distribution boards
- UPS systems
- DG sets
- Earthing systems
- Lightning protection
- Emergency power systems
- Medical electrical systems
- Electrical protection devices
- HVAC systems
- Lifts
- Pumps
- Fire and life-safety systems
- Energy management
- Preventive maintenance
- Electrical documentation and records
The NABH framework helps bring these operational responsibilities into the larger conversation about hospital quality and safety.
The importance of a hospital electrical safety audit checklist
A structured hospital electrical safety audit checklist can help engineering and quality teams systematically review the condition of their electrical infrastructure.
Depending on the hospital, an audit may examine areas such as:
1. Electrical panels
Condition, loading, identification, protection, cable termination, housekeeping and thermal abnormalities.
2. Earthing systems
Earthing continuity, resistance, bonding and other relevant electrical safety measurements.
3. Protection systems
MCBs, MCCBs, RCCBs, RCBOs, overload protection and other protective devices.
4. Emergency power
DG systems, UPS systems, emergency supply arrangements and changeover systems.
5. Critical clinical areas
ICUs, OTs, NICUs, cath labs, diagnostic areas and other critical departments.
6. Electrical shock protection
Assessment of protective measures, socket outlets, leakage protection and associated risks.
7. Thermal imaging
Identification of abnormal heating in electrical equipment and connections.
8. Preventive maintenance
Review of inspection schedules, maintenance records and corrective actions.
9. Documentation
SLDs, electrical test reports, maintenance records, equipment details and other relevant documentation.
10. Risk assessment and corrective action
Prioritisation of findings and tracking of corrective actions to closure.
A checklist is useful—but the ultimate objective should always be risk reduction, not simply completing a checklist.
Why periodic hospital electrical safety audits matter
One common misconception is that an electrical safety audit is required only before NABH accreditation.
That should not be the approach.
Electrical systems change continuously.
Loads increase.
New equipment is installed.
Cables age.
Connections loosen.
Electrical panels are modified.
Temporary arrangements become permanent.
Equipment gets relocated.
Maintenance practices change.
Therefore, electrical safety should be treated as a continuous process.
A periodic electrical safety audit for hospitals provides an independent opportunity to identify emerging risks and verify whether previous corrective actions have actually been implemented.
For hospitals with critical operations, the frequency of assessment should be determined based on the hospital’s risk profile, electrical infrastructure, statutory requirements, equipment condition and operational needs.
From accreditation to everyday safety
There is a potential danger with any accreditation system.
Organisations may focus too heavily on preparing for assessment rather than building systems that work throughout the year.
But the real value of NABH lies elsewhere.
The objective should not be:
“How do we pass the assessment?”
The better question is:
“How do we build a hospital where safe practices continue even when nobody is checking?”
That is where accreditation becomes a culture rather than a certificate.
The hospital should continue monitoring its systems after the assessment.
Engineering teams should continue inspections.
Corrective actions should continue to be tracked.
Risks should continue to be reviewed.
Staff should continue to be trained.
And management should continue to invest in safety.
That is what continuous quality improvement really means.
Our experience at Sustenergy Foundation
At Sustenergy Foundation, we do not see a hospital electrical safety audit as simply an engineering inspection.
We see it as an opportunity to strengthen the reliability of the infrastructure supporting patient care.
Our hospital electrical safety audit services cover critical electrical systems and infrastructure, with an emphasis on identifying electrical hazards, reliability concerns, maintenance gaps and opportunities for improvement.
Our website currently highlights hospital electrical safety audits, energy audits, pre-commissioning electrical inspections and specialist engineering capabilities across healthcare facilities.
Our experience has reinforced one simple principle:
A hospital cannot provide dependable healthcare without dependable infrastructure.
Electrical safety, energy efficiency and infrastructure reliability are therefore closely connected to the larger objective of patient safety.
The NABH journey is far from over
From the first standards introduced in the mid-2000s to the current 6th Edition, the NABH journey demonstrates an important principle:
Healthcare standards must evolve because healthcare itself is constantly evolving.
The introduction of new technologies, changing patient expectations, emerging risks and increasingly complex healthcare facilities will continue to challenge hospitals.
Standards will therefore continue to evolve.
Hospital engineering practices will continue to evolve.
And electrical safety requirements will continue to become more important as hospitals become increasingly dependent on technology.
The NABH 6th Edition is another milestone in that journey, with a stronger focus on quality, safety, risk management, outcomes and continuous improvement.
At Sustenergy Foundation, our experience working with hospitals has shown us both the challenges that remain and the progress that Indian healthcare has already made.
We are proud to contribute to this journey through hospital electrical safety audits, energy audits, electrical inspections and engineering risk assessments.
Because ultimately, the objective is bigger than compliance.
It is about creating hospitals that are:
Safer.
More reliable.
More resilient.
More energy efficient.
And better prepared to protect patients, healthcare workers and critical medical infrastructure.
NABH has helped create a culture of quality.
The journey from the first standards to the 6th Edition represents a movement from basic compliance towards continual improvement.
And for Indian healthcare, that is a journey worth continuing.
