1. Finished in-year admissions
A finished in-year admission is the first period of in-patient care under one consultant within one healthcare provider, excluding admissions beginning before 1 April at the start of the data-year. Please note that admissions do not represent the number of in-patients, as a person may have more than one admission within the year.
PCT and SHA data were 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 are 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 GP practice and SHA of GP practice in 1997-98 and 1998-99 are 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.
2. All diagnoses count of episodes
These figures represent a count of all finished in year admission episodes where the diagnosis was mentioned in any of the 14 (7 prior to 2002-03) diagnosis fields in a HES record.
3. Data quality
Hospital Episode Statistics (HES) are compiled from data sent by over 300 NHS Trusts and Primary Care Trusts (PCTs) in England. The 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.
4. Ungrossed data
Figures have not been adjusted for shortfalls in data (i.e. the data are ungrossed).
Hospital Episode Statistics (HES), The Information Centre for health and social care
Anne Milton: To ask the Secretary of State for Health how many representations she has received on the human papilloma virus (HPV) vaccine Gardasil; whether her Department has conducted an assessment of the effectiveness of new vaccines to tackle HPV; and if she will make a statement. 
The Joint Committee on Vaccination and Immunisation (JCVI) is in the process of thoroughly examining the vaccine safety, efficacy and cost-effectiveness evidence concerning HPV vaccines. The work is being taken forward by a sub-group of JCVI, with further work ongoing to evaluate whether the vaccine is considered to be a cost-effective prevention of cervical cancer; and the impact that HPV vaccine may have on genital warts.
Mr. Baron: To ask the Secretary of State for Health (1) how many faecal occult blood testing kit samples have been (a) returned to and (b) analysed by each of the five national bowel cancer screening programme hubs; 
(2) how many people in England have been invited to participate in the national bowel cancer screening programme; and how many have been sent a home testing kit by each of the five national bowel cancer screening programme hubs; 
Ms Rosie Winterton: As at 16 March 2007, the national health service bowel cancer screening programme had sent out 128,993 invitations for screening. Invitations are sent out one week before the testing kits, and people can opt out of receiving a testing kit if they wish.
110,608 faecal occult blood testing kits had been sent out, and 57,280 had been returned and analysed at the five programme hubs. 1,003 positive results had been recorded, and 92 cancers diagnosed. 292 patients were diagnosed with polyps which may have developed into cancer over time. Treating these polyps has reduced their risk of bowel cancer.

Mr. Laws: To ask the Secretary of State for Health how many staff worked in dedicated complaints units in her Department and its executive agencies in (a) 1997-98, (b) 2001-02 and (c) 2005-06; and how many have there have been in 2006-07 to date. 
The Medicines and Healthcare products Regulatory Agency (MHRA) had no staff working in dedicated complaints units in the Department and executive agencies in 1997-98, 2001-02, 2005-06 and 2006-07 to date.
However the MHRA has had an independent complaints adviser for the whole period to date. This person has complaints referred to them where they cannot be resolved internally to the complainants satisfaction.
