Patient Safety Dashboard 2: Cluster/Region

Today I'm releasing the second of my patient safety dashboards, created using data from the NPSA NRLS. You can find notes relating to the data, and the first dashboard which compares clusters, in my original blog post.  Dashboard number two lets you compare data for organisations within a single cluster or a single region / SHA, or a combination of the two. All the comments I originally made regarding the data still apply, and I'll update that post with any more information I find which is relevant.

You can access the dashboard by clicking the preview picture or the link below; if you've any questions please feel free to leave a comment below or email me at contact [at] haydnwilliams [dot] com

Patient Safety Dashboard 1 : Clusters

Over the next few weeks I'll be releasing some dashboards looking at patient safety data in the UK, specifically that gleaned from the National Patient Safety Agency's NRLS system. The information is made available to the public, and I've done some collation and basic further analysis to create the dashboards. The idea was inspired by a dashboard originally created by Carl Plant. The first board, below, lets you compare stats between 'clusters', i.e.groups of organisations within the NHS which fulfil a similar role. The second dashboard to be released will allow you to compare data between the organisations making up each individual cluster, and the third will concentrate on the performance of single organisations over time. There are a few important points to remember when viewing all the dashboards. They can be read below – please do take a look. Finally, the dashboards are definitely best viewed on a large screen rather than mobile devices.

I don't intend to give any great analysis of the data, but the comparisons between clusters do seem to back up what I suspect would be most people's intuition. The number of reports has remained broadly stable per cluster over time (I have no explanation for the PCO – No Inpatient cluster in 2010-03!). The Degree of Harm profiles don't hold any big surprises either. Average time taken to report is interesting, with Ambulance Services taking noticeably longer than other areas. I should point out that the measure of time taken to report is the median of all the medians presented by the NPSA over all time periods; statistically that might be shaky ground so if I find a better measure I'll update the dashboard accordingly. The fact that 'time taken to report' is calculated based on all data since 2009-09 means that it doesn't necessarily reveal any recent improvements or drops in performance, but I think is still an interesting indicator of general trends for the last couple of years.

 

Notes Regarding All Dashboards:

The Data
All the data used to make these dashboards is publicly available on the NPSA's NRLS website. They have some comments relating to treatment of the data on the front sheet of each workbook; I recommend having a read before drawing too many conclusions from the dashboard data. The information is released on a six-monthly basis, and I've consolidated those individual reports into one big spreadsheet. I then spent some time adding bits and working it up to get some of the extra stats that have been included. The file will be made available to download when the final dashboard is released (i.e. when I've finished altering it to add more analysis!).

 Dates
The dates given relate to the date of release of the data by the NPSA. For example, '2011-09' refers to the most recently published dataset (this month). Each release contains data for a six-month period.

Changes to Organisations
Over the time period that these data relate to, there have been some changes to the organisations concerned. For example: Welsh LHBs have appeared; some organisations have merged with others;  some organisations have moved from one cluster to another. I'm sure there are plenty of these spread around, and my apologies to the organisations concerned if it makes it harder / impossible to compare your figures with everyone else.

Disclosure / Disclaimer
I work in the NHS, as a manager of a risk management software system for a large acute teaching Trust. Data from this system feeds into the NRLS. This dashboard work has been carried out in my own time, and the work / opinions expressed in this blog post are entirely my own and not those of my employer. While I've made some general observations about the data, each organisation is different and there will be a large number of factors affecting any of the organisations listed here. The information presented is as released by the NPSA, and it should be borne in mind that a Trust may have perfectly valid reasons for reporting a very low or high rate of incidents, including IT or staffing issues. These analyses are provided for interest only and may contain errors and omissions.

Ubuntu Home Server (UHS)

I've recently set up a home server using Ubuntu. I thought it might be useful for me to record my experience and any problems / pitfalls / useful tidbits of information I found along the way. It's not been a particularly arduous process, but hopefully this might help someone out in the future.

The hardware I used was a semi-home build; I bought the Intel D525MW motherboard, which has an integrated dual-core Atom 1.66GHz processor, and fitted it into a case along with some RAM and a hard drive. The processing power on the motherboard should be more than enough for what we're asking it to do (see below), and it's low power so that means we can leave it on all the time, and it's passively cooled too. The other advantage is that it's mini-ITX, so nice and small to fit under the stairs where it's going to live. I fitted the board into a cheap no-name mini-ITX case which actually turned out to be decent quality, and added 2Gb Kingston RAM. The hard drive is a Western Digital Caviar Green (low power) 1Tb from a previous NAS setup. There's no DVD drive (what's the point nowadays, really?), and I'm using onboard video and sound.

The software I installed was obviously customised to fit our needs / requirements. I chose Ubuntu as the operating system, because a Mac was too expensive, a Hackintosh was too complicated in terms of finding 100% compatible hardware, and Windows Home Server was discounted for reasons I can't remember right now, but were definitely valid and unresolved. I have a little bit of experience with Linux, but never in an admin role and I've never used Ubuntu before. I have used the Terminal in Mac OS and Linux before, so have some basic competence in that area. I certainly wouldn't class myself as a 'guru' though, so if you're not a Linux whizz then don't worry – if I can manage it, I'm sure you can!

In terms of applications installed, we needed the server to carry out a number of roles:

  • File server (including Bonjour for Macs on the network)
  • DLNA server
  • NTP
  • Web server (including WordPress)
  • Repository / eventually CruiseControl
  • Time Machine backups

I've therefore split the software section up into a number of posts on this blog, all starting with the letters 'UHS':

  1. Installing and Updating Ubuntu
  2. Admin tools
  3. Hardware monitoring
  4. Samba file server
  5. Apache, MySQL, PHP (LAMP) web server + WordPress
  6. SSH and Subversion (SVN)
  7. DLNA media server
  8. Time Machine backups
  9. Network Time Protocol (NTP) server
  10. Calendar (iCal) server
