Key performance measures

Our hospitals’ performance on a wide range of measures is outlined in our annual Quality Report and monitored monthly in submissions to the Trust Board.

Our Quality Report is now included in the Trust’s Annual Report and Accounts, but here is a summary of our recent performance on some of the measures that are particularly important to the large majority of our patients.


Infection control

Western Sussex Hospitals NHS Foundation Trust participates in a number of mandatory and voluntary surveillance programmes to track and reduce the number of cases of hospital-acquired infection we see each year.

The best known of these types of infection are MRSA and C.difficile.

Hospital-acquired infections, 2014/15-2018/19

  2014/15    2015/16    2016/17    2017/18 2018/19
C.difficile    38 36 45 35 31
MRSA 1 0 1 3 0

 

Our target for hospital-acquired infection in 2018/19 was zero avoidable cases of MRSA bacteraemia and 35 hospital-acquired cases of C.difficile.

Performance against these measures is tracked monthly in reports to our Trust Board.


Mortality rates

Hospital death rates are an important indicator of quality of care (although they can also be influenced by many other factors, such as the complexity of the cases being treated) and tracking them over time allows clinicians to identify improvements that can be made to the treatment we provide.

At Western Sussex Hospitals, our performance on three separate measures is reported to the Trust Board each month. These are:

  • crude mortality (deaths per 1,000 discharges),
  • the Dr Foster Hospital Standardised Mortality Ratio (HSMR), and
  • the Health and Social Care Information Centre’s (HSCIC) Summary Hospital Level Mortality Indicator (SHMI).

 

Crude non-elective mortality

  2014/15   2015/16    2016/17    2017/18 2018/19
%    3.27 3.13 3.21 3.10 2.68

 

Our target crude mortality rate for non-elective patients in 2018/19 was 3.10%

Dr Foster Hospital Standardised Mortality Ratio (HSMR)

  2014/15   2015/16    2016/17    2017/18 2018/19
HSMR    95.4 89.6 91.1 88.1 92.0

 

Summary Hospital Mortality Indicator (SHMI)

  2014/15    2015/16    2016/17 2017/18 2018/19
SHMI    1.03 1.00 0.97 0.95 0.98

 

The average mortality rate index is 100 for HSMR and 1.00 for SHMI, so lower rates are better. Our ambition is to be in the 20% of NHS organisations with the lowest risk-adjusted mortality rates.


Pressure ulcers

Numbers of avoidable pressure ulcers are recognised as a key indicator of the quality of nursing care patients receive.

Since 2012, wards at Western Sussex Hospitals have been taking part in an internal award scheme to promote the standards of skin care needed to protect patients in this way.

Hospital-acquired pressure ulcers

  2014/15    2015/16    2016/17    2017/18 2018/19
Grade 2+   87 199 258 356 317

 

The increase in pressure ulcers seen in 2015/16 was due to a change in the way we report skin damage. Our target for 2018/19 was fewer than 220 Grade 2 pressure ulcers. We are continuing to promote good nursing practice to raise standards further in 2019/20.
