The main procedure is the first recorded procedure or intervention in the Hospital Episode Statistics (HES) data set and is usually the most resource intensive procedure or intervention performed during the episode. It is appropriate to use main procedure when looking at admission details, (e.g. time waited), but a more complete count of episodes with a particular procedure is obtained by looking at the main and the secondary procedure.

As well as the main operative procedure, there are up to 11 and 3 prior to 2002-03 secondary operative procedure fields in HES that show secondary or additional procedures performed on the patient during the episode of care.
HES are compiled from data sent by more than 300 NHS trusts and primary care trusts (PCTs) in England. Data is also received from a number of independent sector organisations for activity commissioned by the English NHS. The NHS Information Centre for health and social care liaises closely with these organisations to encourage submission of complete and valid data and seeks to minimise inaccuracies and the effect of missing and invalid data via HES processes. While this brings about improvement over time, some shortcomings remain.
Figures have not been adjusted for shortfalls in the data, i.e. the data are ungrossed.
Time waited (days)
Time waited statistics from HES are not the same as the published waiting list statistics. HES provides counts and time waited for all patients admitted to hospital within a given period, whereas the published waiting list statistics count those waiting for treatment on a specific date and how long they have been on the waiting list. Also, HES calculates the time waited as the difference between the admission and decision to admit dates. Unlike published waiting list statistics, this is not adjusted for self-deferrals or periods of medical/social suspension.
PCT/strategic health authority (SHA) data quality
PCT and SHA data was added to historic data years in the HES database using 2002-03 boundaries, as a one-off exercise in 2004. The quality of the data on PCT of treatment and SHA of treatment is poor in 1996-97, 1997-98 and 1998-99, with over a third of all finished episodes having missing values in these years. Data quality of PCT of general practitioner (GP) practice and SHA of GP practice in 1997-98 and 1998-99 is also poor, with a high proportion missing values where practices changed or ceased to exist. There is less change in completeness of the residence-based fields over time, where the majority of unknown values are due to missing postcodes on birth episodes. Users of time series analysis including these years need to be aware of these issues in their interpretation of the data.
The PCTs used are as follows:
5P3West Hertfordshire PCT
5P4East and North Hertfordshire PCT
Method of admission
The method of admission is how the patient was admitted to hospital. When calculating time waited, admissions are elective so the following methods are used:
11 Electivefrom waiting list
Code 13 Electiveplanned is not included as it has been the patients choice to defer.
Hospital Episode Statistics (HES), The NHS Information Centre for health and social care
Mark Pritchard: To ask the Secretary of State for Health what percentage of people who presented with tuberculosis in 2008 were subsequently diagnosed with acquired immune deficiency syndrome. 
1. This figure is based on the retrospective matching of the national Enhanced Tuberculosis Surveillance database (ETS) and the national HIV/AIDS reports database.
2. Matching is carried out retrospectively because there is often considerable delay in reporting of cases and data are, therefore, available for 2005 only at present.
3. This figure also includes HIV/AIDS patients with TB as an AIDS defining illness who were not identified in the national TB database.
4. The proportion provided is for all cases of co-infection with TB and HIV because we do not have information on which infection was acquired first.
5. This figure does not include cases of co-infection in children because HIV in children is reported separately.
Dawn Primarolo: A vaccine containing diphtheria, tetanus and pertussis (DTP) only, has not been distributed since October 2004 because DTP has been combined with other vaccines. The individual cost of vaccine and the total cost to Government, is commercial-in-confidence.
Bob Spink: To ask the Secretary of State for Energy and Climate Change to which (a) charities and (b) voluntary organisations his Department has provided funding since it was established; and how much funding was provided to each. 
Bob Spink: To ask the Secretary of State for Energy and Climate Change how much coal from what countries of origin was imported in the most recent 12 month period for which figures are available. 
Digest of UK Energy Statistics 2008
Mrs. McGuire: To ask the Secretary of State for Energy and Climate Change what steps the Government are taking to ensure that energy companies reduce diesel prices in line with both crude oil and petrol prices. 
Mr. Mike O'Brien: I recently met with the UK Petroleum Industry Association, which represents fuel retailers, to impress upon them the urgency in passing on any reductions in costs to consumers. Recent increases in the difference between petrol and diesel retail prices are due to a relative shortage of the availability of wholesale diesel due to constraints in refinery capacity.
Helen Southworth: To ask the Secretary of State for Energy and Climate Change what steps he is taking to encourage energy suppliers to (a) publicise the availability of and (b) maximise take-up of social tariffs by eligible customers. 
Mr. Mike O'Brien: Suppliers agreed at the fuel poverty summit organised by Ofgem in April 2008, to provide greater visibility of their offers. Following this Ofgem has worked with the suppliers to ensure that information about their social tariffs and programmes and a contact phone number for consumers to check their eligibility, is available on all the suppliers' websites.
Energy suppliers have committed to collectively spend £100 million this year, rising to £125 million next year and £150 million by 2011 on social assistance. In order to meet this commitment to Government the suppliers need to inform their customers about the assistance available to vulnerable groups through their social tariff scheme.
Expenditure on suppliers' social assistance is monitored by Ofgem and they estimated, in a report published in December 2008, that over 800,000 customer accounts are now benefiting from a social tariff. This is a significant increase, almost doubling, since March 2008 which is a good indication of the level of awareness of the assistance suppliers offer.
Dr. Kumar: To ask the Secretary of State for Energy and Climate Change what his most recent estimate is of the number of people (a) in Middlesbrough South and East Cleveland constituency, (b) the Tees Valley, (c) the North-East and (d) the UK who are living in fuel poverty; and what forecast he has made of the number of people in the North-East who will be living in fuel poverty in 10 years' time. 
Joan Ruddock: The most recent year for which sub-regional estimates of fuel poverty are available is 2003. The data for fuel poverty levels for 2003 come from the fuel poverty indicator dataset available online at:
In 2003, there were around (a) 2,400 fuel poor households in Middlesbrough South and East Cleveland; (b) 17,700 fuel poor households in the Tees Valley; (c) 95,000 fuel poor households in the North-East; and (d) two million fuel poor households in the UK.
John Robertson: To ask the Secretary of State for Energy and Climate Change what discussions he has had with the French Government on nuclear fuel recycling following the agreement between the UK and France to co-operate on nuclear energy. 
To ask the Minister of State, Department for Business, Enterprise and Regulatory Reform what information his Department holds on the number of F16 jets used by the Israeli air force in the
recent military operation over Gaza which contain British-made components; and what steps the Government have taken to ensure that none of the British-made heads up units were incorporated in Israeli F16 jets involved in bombing Gaza recently. 
The UK operates a licensing system built around pre-licensing assessment whereby it assesses the risk of misuse of UK supplied equipment before deciding whether or not to grant a licence. All export licence applications are carefully assessed on a case-by-case basis against the Consolidated EU and National Arms Export Licensing Criteria. Judgments on export licence applications take account of the information and circumstances at the time of application. HMG seeks advice from its advisors in its diplomatic posts overseas in relation to all export licence applications, including for Israel.
Mr. Roger Williams: To ask the Minister of State, Department for Business, Enterprise and Regulatory Reform if he will take steps to ensure that construction companies undertaking public sector infrastructure works are required to employ apprentices. 
To support apprenticeships in construction, Government Departments and agencies have now committed that when they let a new construction contract, they will consider making it a requirement that successful contractors employ apprentices as a proportion of the project work force. We estimate that this will support some 7,000 apprenticeships over the next three years.
