Excerpts
1. Past pandemics and especially
present Covid -19 infection around the globe and in our country, have given us
opportunity to think about future protection from similar attacks and built
systems which are safer, resilient and adaptable.
2. A s Covid -19 infection is going to persist
for some time may be 2 years or so, even after the lockdown is lifted in phased
manner, we need to start afresh with new way of working in our workplace,
hospitals or homes to maintain social distance and hygiene measures for
personal protection as well of ours neighbors.
3. Discussion points: How to maintain
social distance in lifts, clinics, hospitals, factories, public transport
systems, airports etc.; Appropriate
ventilation systems at homes, workplace and hospitals, high risk areas which
are necessary to stop transmission of microorganisms including viruses and
consumer friendly.; Impact of NO TOUCH technology and its utility in cost
effective way; Use of infection resistant materials like wall paints, door
knobs, handles etc. and Decontamination ease
Following
infrastructure related concerns were highlighted by the experts after
deliberations
1. Most importantly, after an episode
is over, complacency sets in at all stakeholder’s levels and learnings are
forgotten to safeguard future calamities.
2. Ventliation is double edges sword,
if not appropriate is rather counterproductive and is den for colonization and
enhance transmission of disease agent.
3. Space management
4. Non utilization of technology and
poor design of the building like green building concepts, natural ventilation
and lighting
5. High cost of establishment and
operative costs
Broad
Solutions suggested are
1. Building designs should be Evidence
based designs (EBD) and meticulous planning to incorporate Green concepts, use
of nature resources like lighting and ventilation, resilient and adoptable for
expansion and contraction of services in time of crisis (need based) as makeshift
arrangement.
To cut down cost, in place of single rooms, Nightingale
wards having large windows for lighting and ventilation, maintaining distance
between beds minimum 1 meter and curtains for privacy. Common hygienic toilets.
For this purpose, provision to be made in
parking areas, lobbies and other space within or near premise to raise modular
structures in minimum time.
Use of auditoriums, conventions halls, sports
auditoriums etc. to turn them into
temporary isolation/quarantine/ triage facilities/primary care/monitoring areas
like Wuhan erected 13 temporary hospitals in such places in hours to a weeks’
time creating 18000 beds with zoning and ventilation. Minimum standards for
quality and safety were implemented in these makeshift arrangements also.
2. To reduce over crowing in OPDs
Provision for large area in OPD to maintain
physical distance
Appointment system
Teleconsultation/video consultation room
3. Triage /screening area for
prioritization of patients, less than 3 minutes for screening to minimize
chances of contact transmission.
4. Separate walkway for movement / transfer of
infected patients from non -infected patients
5. 2-4 patients per lift and separate
corridor and lift for Healthcare workers
6. To reduced transmission by contact: use of sensors for doors, washbasin taps,
flush systems in toilets/urinals.
7. Use of copper alloy (minimum 63%) cu
as bacterial resistance material in doorknobs/handles/railings etc.
8. Sufficient facilities for hand wash
/sanitizers in clinical areas
9. Sufficient AIIR rooms (isolation
rooms) with negative pressure [CDC suggest 1.7 rooms per 10,000 population in
mild epidemic; 6.56 rooms per 10,000 population in moderate epidemic severity
and 61.5 rooms per 10,000 population in
severe epidemic
Ventilation:
involves 4 steps
1. Pressurization
2. Air changes per hours
3. Filtration
4. Purification of exhaust air
Ventilation
systems should follow standards laid down by ASHRAE or other recognized
national standards for installation and operations and maintenance. First 3
processes result in trapping and colonization with microorganisms, purification
of these is most essential and generally this step is not taken care of
adequately resulting in transmission of infection through HVAC system.
Proper
Temperature and Relative Humidity as per need of clinical area is important for
comfort of staff /patient and well as deterrent for infecting agents
Various
methods for purification like HIPPA filtration, UVGI or ionization can be used
in combination
Direction
of air flow is also concern
Provision
for switching of type of pressure from positive to negative in rooms or ICU on
need base can be made
Preventive
and regular maintenance as per guidelines
In any type
of setting varying from a single room clinic to N Homes to tertiary hospitals,
system of adequate ventilation and safe disposal of exhaust air is must and is
feasible by using various technologies. The additional cost of installation is
going to add cost to establishment but is vital for safety of staff and
patients and communities.
Public
Transport
Decongestion
at airports, stations and bus stops is need of hour.
Sitting
norms in airplanes, trains or buses shall change
Bicycle or
two wheelers use to be encouraged
Minimum
Quality standards should be made mandatory for all types of health facilities
Standards
to include social distancing norms and infection prevention & control
measures
Meeting
ended with vote of thanks to chair and participants. It was decided to hold 2-3
more sessions to discuss technical details.
Copy of
guidelines issued by CPWD for ventilation and by IDA for Dental facilities are
