TERMS AND CONDITIONS
FOR INSTALLATION AND OPERATION OF 3 TESLA M.R.I SERVICES
1. INTRODUCTION
This ‘public Private partenership’ represents the agreement
between Banaras Hindu University (hereby ‘first party’) and a private party, to be
selected from the bidders, on the basis of an open online tender as per Government of
India specified procedure (hereby ‘second party’) for the provision of services
concerning 24x7x365(/366) hours (hereby ‘round the clock’) Magnetic Resonance
Imaging facility (hereby ‘facility’) at the premises of the newly constructed BHU Trauma
Center. This arrangement is intended to provide a framework for establishing a
cooperative and productive working relationship between the First party and the second
party. In nutshell, the first party would provide the space for installation of the said
facility and high-level technical expertise (both as per pre-designated and mutually
agreed upon terms & conditions), in order to achieve the under-mentioned ‘goals’ and
‘objectives’ while the second party would be obliged to bear all other expenses and
damages, if any. This agreement defines the terms and conditions under which the first
party and the second party will interact with each other. It is anticipated that this
arrangement will result in more efficient operations and improved utilization of
resources.
2. STATEMENT OF PURPOSE
In view of the exponential expansion of services at the Sir Sunderlal
hospital (hereby ‘SSH’), due to the commissioning of the upcoming trauma center (in
Page 7 of 57
near future), provision of 24x7x365(/366) MRI facility seems to be an essential
component. The proposed 3 Tesla MRI unit at the trauma center under a Public-Private
Partnership Program (hereby ‘PPP’) will provide the first party and SSH with the much
needed MRI facility. The prime mandate of the facility would be twofold:
a) To provide un-interrupted services to patients presenting/being referred to
SSH/Trauma Center for treatment.
b) To provide facility for training and research in the field of ‘MR Imaging’, to the
Department of Radiodiagnosis & Imaging (hereby ‘department’) and to all other
relevant units/sections/departments of this first party, through the Department of
Radiodiagnosis & Imaging.
3. AGREEMENT OF TASKS, PERMISSIONS AND COMPETANCIES
The sole responsibility and right of the second party would be to
provide round the clock un-interrupted MRI services to patients presenting/being
referred to SSH/ Trauma center for treatment. The facility will include comprehensive
range of MRI based investigations, living up to the cause and quality of a level I trauma
center and a tertiary care teaching hospital. The academic aspect of MR Imaging (i.e.
teaching, training, research, organization of academic activities like conferences, CME,
symposia, seminar etc., academic publications in books, journals and conferences and,
collaboration with any other academic body/unit/department/section/faculty for the
purpose) and MRI would however be the sole prerogative of the department. Any
autonomy asserted by the second party of any sort in this regard would be considered
as a breach of agreement and liable to suitable action.
Page 8 of 57
The technical features and specifications of MRI System, to be
installed by the second party, shall NOT be anyway of lower configuration as mentioned
in the Tender document, otherwise the bid shall be rejected. Please be informed that if
any of the points in the technical specifications (provided as a part of this document in
Annexure) is manipulated/ over sighted or neglected in the technical bid and, the same
is proven after the installation of the facility, the second party shall be under a binding to
take suitable measures to rectify the challenged clause entirely at it’s own cost. The first
party shall bear no responsibility to this effect and the extra expenditure would show no
where against the first party liabilities. The First party reserves the right not to consider
unviable financial bids if the rates of MRI are quoted so low in conjunction to investment
which may make the project unviable in financial terms.
Approved bidder shall install a brand NEW MRI System (as per
Annexure VI) with all accessories and facilities necessary for optimum
functioning within 240 days from the date of signing of the agreement/MOU with the
First party. For delayed installation beyond the aforesaid period a penalty of Rs.25,000/-
per week shall be levied. If the facility is not made available to the first party within 60
days from the expiry of the scheduled time period of installation, the order would stand
automatically cancelled and security deposit shall stand forfeited.
The agreement shall be valid initially for a period of seven years
from the date of commissioning of the facility, and it could be revoked at any timeon
account of violation of rules, regulations, terms and condition of the contract by the
second party, after providing an opportunity of hearing. Periodical inspection for
performance and observance of terms & conditions including quality of MRI
Page 9 of 57
investigations shall be carried out every year by a committee appointed by the first
party. The second party shall arrange a 3rd party insurance policy to cover all the
patients, subjected to MRI investigations, against any mishap at MRI centre, conforming
to the provision of the ‘Consumer Protection Act (1986)’, entirely on it’s own absolute
responsibility. Privacy and other ethical values of investigated patients will have to be
maintained in individual case.
The second party shall abide by all the guidelines issued by the
Government of India and the first party from time to time during the lease period. Please
be informed that the second party status, as a whole or in part, is non-transferable and,
the awarded second party shall not sell or transfer by any mode whatsoever any
proprietary right or entrust any other party to run the MRI/facility.
In the best interest of patient management, as far as prompt
reporting of MRI scans is concerned, the second party would be free to share all MRI
scans done after the routine working hours (9 AM to 5 PM) of the first party and certain
other pending cases, with a third party (defined hereby as a person with such
reasonable level of experience and expertise so as to report MRI scans, either directly
or through mass communication modalities). In this case it would be the responsibility of
the second party to ensure patient privacy and protection of academic data by electronic
coding and encryption methods.
Please be informed further that the trauma center is likely to have
patients with medico-legal registration as well, hence privacy and protection of data
would be of prime importance. The ‘department’ would be obliged to co-operate to the
Page 10 of 57
best of it’s ability as far as clinico-radiological evaluation and subsequent documentation
of results of the MRI scans is concerned. It would however be the final responsibility of
the second party to manage the reporting of all MRI scans within a reasonable duration
(as decided by the patient triage protocol fixed in the trauma center).
4. INSTALLATION AND OPERATION OF THE FACILITY
The Turn-key execution will have to include standard architectural
programming and selection of interior materials having ease of replication &
maintainability. The space for installation of MRI, as specified by the equipment vendor,
would be provided by the first party in the premises of trauma center. The second party
shall be solely responsible for construction of the building as per specifications by the
vendor with no liability on the part of the first party. All the civil, electrical, air-
conditioning provisions (considered essential for installation of MRI) shall be the
responsibility of the second party. The first party will not be responsible for any loss /
damage to machine or property due to natural calamity or otherwise.
Please be advised that MRI is a highly specialized equipment with
peculiar and specific needs in terms of above mentioned as well as topographical
requirements, it is therefore the responsibility of the second party to inspect (in minute
details) and ensure the suitability of the site as provided by the first party. In case it is
brought to the notice of the first party, with documented justification, that the site
provided is not suitable in any respect, the first party would provide another space
suitable to the needs of the facility installation as well as the patient management. No
Page 11 of 57
representation of any sort whatsoever would be entertained by the first party, once the
site has been ear-marked.
The building constructed by the second party shall become the
property of the first party, after expiry of agreement/MOU period. All expenses on
account of electricity, water, maintenance of premises and the equipments or any other
expenses incurred in day to day running of MRI system shall be borne by the second
party. The security arrangement and cleanliness of the equipments & house-keeping of
the facility will be sole responsibility of the second party. The second party will have to
procure a stand-by source of power (Generator Set), capable of catering the power
requirement of MRI with all accessories and facility as such, so that services remain
available un-interrupted round the clock.
5.HUMAN RESOURCE
The technical staff, recruited by the second party, should have the
qualification specified by the first party (Annexure IV), any deviation from the same
would be taken as a breach in agreement and be liable for suitable actions. The second
party shall arrange for the services of an anesthetist and/or an emergency medical
officer who would be responsible for the smooth execution of the case/scans and
monitoring of patients while inside the premises of MRI unit. The said officer would have
the ‘right to refusal’ to be recorded in writing with supporting reason, for accepting a
patient for scan if he/she feels that a patient is too critical for him to monitor and there is
no attending clinician accompanying the patient. The staff of second party would ensure
Page 12 of 57
good medical practice and high ethical values towards patients under overall control of
the department.
The bad quality MRI scans will have to be repeated at no extra
cost. As regards to the doubtful observations or incomplete study, a repeat scan will
only be carried after review by the head of the Department of Radiodiagnosis and
Imaging (hereby ‘the head of the department’). The proposed MRI facility shall allow
members of all 3 faculties (i.e. Medicine, ayurveda and Dental sciences)of IMS to have
access to view MRI Scans of their respective patients for clinical management. If and
when the First party starts HIS and PACS, the patients’ data available on MRI would
have to be made accessible to these systems. The second party will have to do 20
(twenty) numbers of FREE cases (noncumulative) per month after prior sanction of the
head of the department, who would be the sole authority to decide the cases to be
performed in this category.
The MRI scans of bonafide BHU staff and their dependents, as well
as bonafide BHU students shall be done free of cost initially. There would be
arrangements made by the first party to re-imburse the collective charges borne per
month in this category by the second party.
6. ACCOUNTING PROCEDURE / REVENUE COMPUTATION
The MRI facility, as proposed within the frame work of PPP, is
being created will have to offer best clinical quality at an acceptable cost. The MRI
charges from all patients would be collected by the first party on AR-1. The scans to be
Page 13 of 57
performed under various sub-categories of MRI investigation (Annexure V), would have
to be executed at a pre-decided rate.
The rate list to be generated as per mutual agreement between
the first party and the second party as per the mentioned categories (Annexure V) and
would be decided on the basis the financial bid, for the ‘ordered primary region’ (Please
refer to the Table no. 1 and Case Illustration 1).
Single sequence screening (i.e. consisting on one MRI
sequence considered most suitable to answer a clinical question by the referring
clinician) of single anatomically contiguous region would be done at 1/5th the cost of
‘ordered primary region’ (and would be performed only along with another ‘ordered
primary region’). The question, as to whether adjacent contiguous regions be
considered as one or as two, would be addressed by the maximum area reasonably
coverable by the equipment (i.e. the relevant coil) without any loss of clinical quality.
Special investigations consisting of MRCP, non-contrast
MRA, MRS, CSF flow, MR Perfusion study, DTI, tractography would be done at 1/3rd the
cost of ‘ordered primary region’ (and would be performed only along with another
‘ordered primary region’) (Ref. Table 2). Procedure based MRI investigations like MR
arthrography, contrast enhanced MR Angiography, MR Enteroclysis would be
considered as an ‘ordered primary region’, but would attract an additional 1/10th cost as
procedure charges. In case the same are requested along with another ‘ordered primary
region’, an added cost of single region screening (i.e. 1/6th the cost) plus procedure
charges (i.e. 1/10th the cost) would be incurred (Ref. Table 3).
Page 14 of 57
A reasonable (between Rs. 1000 and Rs. 1200 only) cost of
MRI contrast medium would be charged on separate AR-1 receipts (the same would
have to be of the best quality, duely approved for human use) (Ref. Table 4). This would
include the disposables required for administration of contrast media. The second party
would be free to use the facility for patients being referred from physicians not engaged
with the first party, if any, at the same rates, charges of which will be collected by the
first party. However, priority shall always remain for patients referred from SSH/trauma
center.
