Finished in-year admissions
A finished in-year admission is the first period of in-patient care under one consultant within one health care 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.
Figures have not been adjusted for shortfalls in data (i.e. the data are ungrossed).
Time waited (days)
Time waited statistics from Hospital Episode Statistics (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. Where there is no recorded entry for decision to admit, or when decision to admit and admission date are the same this creates an invalid waiting time. Unlike published waiting list statistics, this is not adjusted for self-deferrals or periods of medical/social suspension. The time band one day to under six months includes those who waited one to 182 days, the six months to under 12 months includes those who waited 183 to 364 days, the 12 months and over includes those who waited 365 and over days.
Primary care trust (PCT) and 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 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.
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.

Mr. Kemp: To ask the Secretary of State for Health how many and what percentage of people in (a) Houghton and Washington East constituency and (b) Sunderland city council area were waiting more than (i) three months, (ii) six months and (iii) a year for an NHS treatment for (A) cancer and (B) heart problems in each year since 1997. 
Information is collected on performance against the cancer waiting times standards of a maximum wait of 31 days from diagnosis to first cancer treatment and a maximum wait of 62 days from urgent referral to first cancer treatment, which were introduced for all cancer patients from December 2005. Data giving performance against these standards for the period July to September 2006 shows that patients at the City Hospitals Sunderland National Health Service Foundation Trust achieved 99.4 per cent. and 96.7 per cent. respectively.
