§ Tim Loughton
To ask the Secretary of State for Health (1) how many MASH type mobile operating theatres are(a)in use and (b)on order; 
(2) what the average cost is of the MASH-type mobile operating theatres being supplied to hospital trusts; 
(3) what guidance has been issued to hospital trusts looking to acquire MASH type mobile operating theatres; 
(4) which hospital trusts are negotiating to acquire MASH type mobile operating theatres. 
§ Mr. Hutton
The Department does not collect data on how many NHS Trusts are negotiating to acquire mobile operating theatres, or on how many trusts already have them in place. The purchase of mobile operating theatres is a matter for individual NHS trusts to make, in partnership with their commissioners.
Costs for the provision of mobile operating theatres vary according to the type of facility, the costs of securing plumbing and power, and the length of time the facility is likely to be in operation, as well as a range of site-specific conditions. However, the approximate costs are £3,600 a day or £12,000 per week for a "low loader" facility (which can he moved around from day to day) and for Modular kits, which provide a fixed-temporary service, the cost is £1,200 a day or £750,000 as an outright purchase.
Guidance on ventilation in health care premises and operating departments have been issued by NHS Estates. In 1991, NHS Estates issued "Health Building Note 26 on Operating Departments" which covers the planning and design, including space requirements, maintenance, cleaning, energy consumption, engineering and staffing requirements. While the guidance does not refer directly to mobile operating theatres, the standards set out in the guidance applies to all types of operating theatre. Health Technical Memorandum 2025 was issued in 1993 and sets out how the NHS can ensure facilities control and reduce hazards to patients and staff from airborne contaminants, dust and harmful micro-organisms.
