Why are data items selected?(What is HSE used for? ) • To inform Government on where to allocate their resources • Tobacco control campaigns • To increase fruit and vegetable consumption • To provide valuable information to help make people’s lives healthier, and encourage them to make healthier choices • To set out and monitor key health objectives • Obesity, CVD, respiratory disease
HSE special topics • Cardiovascular disease • 1991-1994, 1998, 2003, 2006 • Respiratory disease, accidents & disability • 1995, 1996, 2001, 2002, 2010 • Physical activity • 1997, 1998, 2003, 2006, 2008 • Young people • 1997, 2002 • Older people • 2000, 2005 • Minority ethnic groups • 1999, 2004 • Knowledge and attitudes • 2007 • Kidney disease • 2009
How modules & data items are selected now1. Funding • 1991 – 2004 • HSE funded by Department of Health (DH) • 2005 - 2009 • HSE funded by NHS Information Centre (IC) • HSE 2010 and HSCS 2011 onwards • Core funded by IC • Additional modules / Boost groups funded by relevant groups in DH
How modules & data items are selected now2. Core item selection HSE 2010 and HSCS 2011+ • Consultation process before HSCS tendered • Ascertain necessity and content for HSCS from stakeholders and data users • Discussions between IC and Joint Health Surveys Unit (NatCen + UCL) • Proposals costed by NatCen • Discussions by HSCS Steering Group • Balance between ‘wish list’ and costs • Increased length of core interview from 30’ to 50’ (concurrent interview with two people) • Reduced content of core nurse visit
Household questionnaire Individual interview Precise content under discussion with Steering group Height & weight (measured) Core content Stage 1: Interviewer visit
Interview visit: New from 2010 • New from 2010 • Self-care plans • New from HSCS 2011 • Social care
Proposed core content Stage 2: Nurse visit • Questionnaire • Measurements • Eg Blood pressure • Samples
How modules & data items are selected now3. Additional modules HSE 2010 and HSCS 2011+ • JHSU run workshops for DH staff • Discussions between IC & DH and IC & JHSU • Proposals costed by NatCen • Discussions by HSCS Steering Group • Major focus for next five years • Balance between ‘wish list’, costs, and duration • Limited options for additional interview questions • Self-completions in nurse visit • Additional analytes from blood samples
How were recent new modules selected?1. Physical activity HSE 2008 • Increasing levels of obesity • Population leading increasingly inactive lifestyles • Physical activity only an intermittent module (too time-consuming) • Revised questionnaire for adults and children (longer!) • Increased accuracy of estimates • Bring questionnaire in line with new government guidelines • Objective measurement • Actigraph TM1 • Objective measurement of fitness • Step test
The step test:Indicator of health risk independent of obesity • Measure of functional aerobic work capacity (Vo2max) • Stepping exercise to a set rhythm, getting faster • Heart rate recorded while stepping and afterwards • Validation study • Practicality (eg size of step) • Validity of data
How were recent new modules selected?2. Respiratory disease and function HSE 2010 • Why chosen? • New DH standards on identifying and treating chronic respiratory disease due 2010 • Need baseline data then monitoring progress • How chosen? • Proposed by JHSU • Funded by DH • How measured? • Revised questionnaire (previously conducted in 2001) • Objective measurement of lung function
How were recent new modules selected?2. Lung function measurement HSE 2010 • Research by JHSU • Cost • Practicalities • Support • Data quality • Decision from DH on equipment • Dress Rehearsal September 2009 • Feedback from nurses • Review data collected • Amend training • Launched January 2010
