Status of this report
This information pack has been produced to share summary information from analysis which has been used in determining the potential options for the acute reconfiguration of West Hertfordshire Hospital Trust (WHHT) estate. The options appraisal is to support the refresh of the acute reconfiguration Strategic Outline Case during 2018/19.
The analysis summarised in these packs is based on data and assumptions provided by WHHT, Hertfordshire and West Essex Sustainability and Transformation Partnership, and professional advisors. Publicly available data was also gathered from Office of National Statistics and Google Distance Matrix API. Hospital Episode Statistics data was provided by Dr Foster. These data and assumptions were gathered during or before December 2018, and analysis has been conducted over the period from December 2018 through to February 2019.
The analysis included in this document does not indicate a preferred option or pre-suppose the outcome of the current shortlisting process. No decisions have yet been made regarding any preferred solution(s).

Population Analysis
� Herts Valleys Clinical Commissioning Group (HVCCG) Population is expected to increase by around 12% over the next 20 years. The largest rate of population growth will be in the 65-85 and 85+ age cohorts.
� The greatest population growth is expected to occur in Watford and Three Rivers (13%), and Dacorum (13%). Lower population growth expected in St Albans (10%) and Hertsmere (10%).
� Each district has housing plans at various stages of development, most of these continue to develop housing in already populated areas, although there are new housing developments planned around the north and east of Hemel Hempstead and to the south of St Albans district.
� Housing plans are greater than expected population increase. Guidance from NHSI is to use ONS population projections for demand forecasting rather than local housing projections.
� Demographic growth for the demand modelling is calculated to be higher than population growth as it accounts for the fact that the elderly population are higher users of healthcare services.

Catchment Area Analysis
� The majority of hospital activity remains within respective CCG borders, i.e. the majority of patients appear to travel to a hospital within their CCG.
� Some patients do travel out from Dacorum to Stoke Mandeville Hospital, from St Albans to Lister Hospital and Luton & Dunstable Hospital, and from Hertsmere to Barnet Hospital and Chase Farm Hospital.
� If there was a central Emergency hospital in Herts Valley CCG then the catchment population could increase - depending on location of site. (as a central hospital would draw activity from Luton & Dunstable, Lister, and Barnet Hospitals). [NB: this assessment is based on travel times/distances only and not on the range of services delivered]
� If there was a single Planned Care site at Hemel Hempstead Hospital (HHH) St Albans City Hospital (SACH) then it would likely pick up a similar size population catchment to the current two sites combined. A single planned care site on the M1-J8 could attract an increased catchment population drawing from Barnet and Luton & Dunstable Hospitals. [NB: this assessment is based on travel times/distances only and not on the range of planned care services delivered]

Travel Time Analysis
� Average travel times from Dacorum and St Albans to Watford General Hospital are higher than from Watford, Three Rivers and Hertsmere.
� Average travel times from Dacorum and St Albans to Watford General Hospital are higher than to other (closer) Emergency hospitals.
� More people travel from St Albans and Dacorum to Watford General Hospital than would be expected given the travel times and distances.
� If patients travelled to their closest hospital by travel time for emergency activity – Watford General Hospital catchment would reduce and travel times for St Albans and Dacorum patients would significantly improve.
POPULATION ANALYSIS

Population Analysis – data sources and description
• Population estimate by Lower Super Output Area (LSOA), based on Office National Statistics mid-2017 estimates (released October 2018). Used to produce current maps.
• Population projection by district, based on Office National Statistics mid-2016 basis (released May 2018). Used to produce future maps.
• Population projection by CCG based on Office National Statistics mid-2016 basis (released May 2018). Used as basis for demand modelling.
• Note the methodology for estimating migration changed between the ONS-2014 population projections and ONS-2016 population projections, this produced a lower population projection from ONS-2016 vs ONS-2014.
• Latest housing plans reviewed from each district council and population growth adjusted for areas of expected new housing developments (but still using ONS population projections as forecast).
• Maps have been produced for 2018 and 2038 populations, along with an underlying LSOA level dataset.

Demographic Growth vs. Population Growth
Demographic Growth must account for not only population increase, but also the changing demographics of that population
• Population projections for demand modelling are based on Herts Valley CCG population recognising that most WHHT activity comes from HVCCG
• Population projections for demand modelling use five separate age cohorts (0-15, 16-39, 40-64, 65-84, 85+) recognising that older people use services most frequently
• This results in a 20 year demographic growth of around 20% as opposed to overall population growth of 12%.

CATCHMENT AREA ANALYSIS
14© PA Knowledge Limited | Not Confidential
Catchment Area Analysis – data sources and descripti on
• Activity data is shown for each point of delivery (POD), and maps are included for West Hertfordshire Hospitals.
• Activity data is taken from Hospital Episode Statistics (HES) and is the average of last 3 years (15/16-17/18) rounded to the nearest 100. From “MSOA_local_322” dataset (see Appendix).
• Activity data is provided by trust & site (not by CCG & district) so column totals will be 100% of trust activity, row totals will not be 100% of district activity (i.e. for some districts their activity will happen at hospitals outside of WHHT’s local neighbouring hospitals).
• Districts are grouped into Herts Valley CCG (HVCCG), South of HVCCG, North/East of HVCCG and West of HVCCG.
• Bold values show where activity is greater than 5% of a hospital’s activity.
• “Emergency department” activity is “Type 1” (i.e. A&E department) and includes both majors and minors.
• “Other A&E” activity is “Type 3” (i.e. Minor Injuries Units or Urgent Treatment Centres), This cant be broken down to site, so is shown as pairs of sites or unknown.

TRAVEL TIME ANALYSIS
35© PA Knowledge Limited | Not Confidential
Travel Time Analysis – data sources and description
• Travel times are taken from Google Distance Matrix (an API which allows the user to pull near real time travel information used by Google Maps).
• Travel times have been taken for different geographical areas (Lower Super Output Area [LSOA] and Middle Super Output Area [MSOA]) to all local hospitals and potential greenfield sites (see Appendix).
• Travel times are based upon three modes of transport (“busy road” = 90th percentile of road journey times, “average road” = median for road journey times and “public transport”).
• MSOA travel times are based upon three times of the week: Tuesday morning at 8am, Thursday midday at 12pm, and Saturday afternoon at 2pm. LSOA travel times are based upon a Tuesday morning at 8am.
• Travel times shown in this section are from two datasets:• The Herts Valley CCG analysis is based upon LSOAs within Herts Valley CCG (these are
shown in the HVCCG LSOAs dataset - see Appendix)• The local districts analysis is based upon MSOAs where activity travels to local hospitals
(these are show in the “MSOA_local_322” dataset – see Appendix).

• This analysis looks at the travel times and distances for Planned Care (Elective Inpatients, Day Case and Outpatients) for people living within the Herts Valley CCG border and travelling to St Albans City Hospital (SACH) or Hemel Hempstead Hospital (HHH).
• The travel times are based on median road times on a Tuesday morning at 8am taken from Google Distance API.
• J8 M1 is used as an indicative site between the two current sites with good road access, but other sites may be considered.
• The new two site scenarios (SACH only, HHH only and New Site (J8 M1)) assume catchment areas remain the same – i.e. people within Herts Valley who used to travel to either SACH or HHH, will continue to travel to the future Planned Care site, whether that be at SACH, HHH, or the New Site.
