Changing practice

Using high-impact interventions to reduce infection risk by standardising good practice

  • Comment

Standardising care by implementing, monitoring and evaluating high-impact interventions can improve practice and reduce the risk of infection in hospital

 

Abstract

Coghill, E. (2009) Using high-impact interventions to reduce infection risk by standardising good practice.Nursing Times; 105: 28: early online publication.

This paper describes the implementation of three high-impact interventions across an NHS trust with the aim of reducing the number of healthcare-associated infections. The initiative was phase 1 of the trust’s implementation of seven interventions identified in the Department of Health’s Saving Lives programme as reducing infections in patients at increased risk. E-learning, reviews of documentation and policies and procedures were used to support the implementation process.

Keywords: Infection prevention, High-impact intervention, Risk assessment

Background

  • Healthcare-associated infection (HCAIs) are those acquired while in hospital or as a result of healthcare interventions.
  • Hospital-acquired infections develop at least 48 hours after a patient has been admitted to hospital, or up to 48 hours after discharge (Jamison, 2008). Outside this period, infections are considered to be community-acquired.
  • In 2004, there were an estimated 300,000 HCAIs each year (House of Commons Committee of Public Accounts, 2005).
  • The Saving Lives programme (DH, 2006) was introduced to support healthcare providers in reducing HCAIs. It identified seven high-impact interventions relating to areas of clinical practice where patients are at increased risk of infection, with the aim of reducing variations in care.

The effects of HCAIs vary from discomfort for the patient to prolonged or permanent disability or death. A small proportion of deaths each year are primarily attributable to hospital-acquired infections. In 2007, around 9,000 people died with MRSA bloodstream infections or had Clostridium difficile identified as the underlying cause or as a contributory factor (Office for National Statistics, 2008).

On average, an infection adds 3–10 days to a patient’s length of stay in hospital. It can cost £4,000–£10,000 more to treat a patient with an infection than one without an infection (DH, 2008).

It is not surprising that attention has been focused on tackling HCAIs and, in particular, MRSA and C. difficile, as these two present a number of challenges to healthcare professionals. Since the publication of the chief medical officer’s report Winning Ways (DH, 2003), action has been taken to reduce rates of infection in a number of ways. These include:

  • Setting challenging target to reduce MRSA bacteraemia;
  • Introducing statutory requirements on cleanliness and infection prevention and control to the NHS in the Health Act 2006 and, more recently, the Health and Social Care Act 2008;
  • Launching the DH’s national; Saving Lives programme with tools to help acute trusts to embed robust infection prevention across their organisations (DH, 2007);
  • Introducing a comprehensive surveillance system for HCAIs by the Health Protection Agency.

While there has been a focus on improving cleanliness in hospitals, this is not the only way in which health professionals can reduce their patients’ risk of infection. Sustainable reductions in HCAIs such as MRSA and C. difficile require the proactive involvement of every member of staff across all healthcare settings.

Implementing high-impact interventions in an NHS trust

The Newcastle upon Tyne Hospitals NHS Foundation Trust has six hospital sites with nearly 2,000 beds and over 11,000 employees, of whom 6,500 are clinical staff. In 2008, the trust implemented its local version of the national Saving Lives campaign.

Saving Lives: Reducing Infection, Delivering Clean Safe Care (DH, 2007) states that the risk of infection to patients can be reduced if healthcare staff consistently comply with evidence-based practice and guidelines every time they undertake a clinical procedure.

Seven high-impact interventions (HIIs), also named care bundles (Box 1), form part of the Saving Lives programme. The interventions relate to specific aspects of care in which clinical procedures can increase the risk of infection if they are not performed correctly. They highlight the essential elements of carrying out a particular procedure that must be applied every time to reduce risk to the patient. 

The purpose is to minimise variation in practice and help to provide ways of identifying where compliance needs to be increased and how often all elements are performed for a given procedure.

Box 1. Focus of the high-impact interventions

  1. Central venous catheter
  2. Peripheral intravenous cannula
  3. Renal catheter
  4. Prevention of surgical site infection
  5. Ventilated patients
  6. Urinary catheters
  7. Reduction in the risk from Clostridium difficile

We introduced Saving Lives in two phases - phase 1 in June 2008 and phase 2 in September 2008. Phase 1 focused on three HIIs:

  • Intravenous line care (peripheral and central);
  • Urinary catheter care;
  • Asepsis.

Phase 2 focused on the remaining HIIs. This article describes the implementation of phase 1.

Developing the programme

The director of nursing and patient services had overall responsibility to deliver the Saving Lives programme. A multiprofessional trust steering group was formed to take the lead on the overall progress and implementation of phase 1. Members included:

  • Director of infection prevention and control;
  • Members of the senior nursing team;
  • Senior members of the infection control team;
  • Assistant director of quality;
  • Antimicrobial pharmacist;
  • Practice improvement facilitators;
  • Hotel services.

Funding was secured from the strategic health authority to appoint a dedicated clinical practice team in April 2008 for a period of 12 months. This consisted of five practice improvement facilitators (PIFs) to assist with the implementation of the programme. All were nurses from various clinical backgrounds covering both paediatric and adult areas.

Subgroups of the steering group were formed for each HII. They undertook an initial analysis to determine existing standards and policies, education and training, and clinical practice. The subgroups were led by a senior nurse and a medical consultant from different clinical areas.

The nursing and patient services department and the clinical governance and audit department developed an audit pro forma that included an accreditation scheme that would measure compliance with the Saving Lives programme. This was known as the ward accreditation scheme.

Initiatives launched in phase I

Phase 1 of Saving Lives has resulted in a number of new initiatives across the trust.

Standards and policies

New standardised insertion and ongoing care documentation in the form of stickers were developed for peripheral, central line cannulas and urinary catheters. These were designed with assistance from our supplies department. The stickers are peeled off a roll and stuck onto patient documentation. Peripheral cannula stickers are placed in a patient’s drug chart and a central line and urinary catheter insertion sticker placed in the patient’s medical and nursing notes. New policies and guidelines for these clinical procedures were developed to include attaching the stickers.

Peripheral cannulas are inspected as part of the drug round and CVCs and catheters are checked when a patient’s systemic observations are recorded.

The PIFs worked closely with all clinical staff at the ward and department level to ensure that documentation was used and clinical practice conformed to new policies and standards. 

Education and training

When phase 1 was launched, 2,500 clinical staff attended a session informing them about Saving Lives and the trust’s response to it.

E-learning packages about the care bundles and asepsis were developed for clinical staff, with questions asked at the end of the training to reinforce learning. These highlighted the critical elements required for asepsis, and peripheral cannula, urinary catheter and central venous catheter care HIIs. All clinical staff are expected to undertake the learning packages if they care for patients with any of these medical devices.

One PIF managed the development and publication of the packages, which take approximately 5–10 minutes to complete. To date, nearly 5,000 clinical staff have completed them.

Competency assessment documents were also developed to complement the e-learning packages. The ward sisters and/or clinical educators are responsible for monitoring their clinical staff.

Laminated posters were designed to reinforce the critical elements required every time clinical care was undertaken. These were strategically placed in treatment rooms where the majority of procedures are undertaken.

Information for patients and visitors

The steering group worked with a design company to develop Saving Lives material for patients and visitors. A patient cannula card was designed to help empower patients to tell staff when their cannula site was painful or looked red. Visitor leaflets were produced, along with posters, to inform the public of the campaign.

Results

The ward accreditation scheme and additional audits have assisted with monitoring compliance of the Saving Lives programme. Ward accreditation results have shown continuous improvement with scores for asepsis, peripheral cannula, urinary catheter and central venous catheter care and taking of blood since the launch of Saving Lives (Fig 2).

One key element of the Saving Lives Programme is to stop unnecessarily peripheral cannulation. This is highlighted in the e-learning package, in which staff are asked to question the need for a cannula to be inserted.

Trust peripheral cannula audits have shown a continued reduction in the number of patients undergoing this procedure. In June 2008, the total number of patients with cannulas in place on one day was 469, compared with 322 in January 2009 (Fig 3).

A DH team visited the trust in December 2008 and found 100% compliance with Saving Lives documentation. They felt that incorporating the inspection of peripheral cannula sites with the drugs round was extremely effective and have recommended this practice and intend to share the examples of our documentation with other organisations.

Summary

So far, the implementation of Saving Lives across our organisation has been successful. In particular, we have reduced the number of cannulas inserted. We continue to work hard to maintain the momentum and provide the highest quality clinical care in our hospitals.

Practice points

  • Standardisation of practice in areas of care where patients are at increased risk of infection can help to reduce the risk of healthcare-associated infection in hospital patients.
  • If infection prevention is to be successful, all staff must be involved in implementing procedures that reduce the risk of infection and patients must be educated and empowered to alert staff to early signs of infection.
  • Using high-impact interventions such as those developed for the Saving Lives programme in areas where patients are at increased risk of infection produces measurable results.
