The impact of comorbidities on referral to and outcomes of hip and knee replacement surgery

New CLAHRC research looks at how comorbidities – multiple conditions experienced by patients –  influence referrals to, and outcomes of hip and knee replacement surgery.

Taking a 360-degree view of the referral and treatment process our researchers, led by Bélène Podmore, investigated current evidence in this area for patients with multiple conditions undergoing surgery. We examined;

  • the short-term outcomes relating to the safety of the hip or knee replacement surgery
  • long-term outcomes relating to the benefits of undergoing hip and knee replacement surgery.

We found comorbidities predominantly impact the safety of hip and knee replacement surgery but have little impact on its effectiveness.

Bélène also interviewed a variety of health professionals and therapists for their take on referring and selecting patients with comorbidities for joint replacement surgery.  We found some disagreement among professionals – ranging from GPs to surgeons – on roles and responsibilities in the management of these patients.

The two pieces of research are presented in handy new “BITE-sized” summaries with links to full papers and further reading –

From theoretically informed to theoretically informative improvement research

A new BMJ Quality and Safety editorial by Dr Roman Kislov, Senior Research Fellow at the Alliance Manchester Business School, has highlighted CLAHRC work as an example of successful engagement with management theory by researchers.

Dr Kislov’s research focus is the processes and practices of knowledge mobilisation, and his editorial highlights our recent paper on how different NHS Boards implement a quality improvement intervention – the QUASER guide.

He cites the paper as “an example of successfully deployed theoretically informative approach, highlighting some practical tips for researchers who aspire to move from merely applying theory towards entering into dialogue with it and, through doing so, refining its assumptions.

Engaging with theory: from theoretically informed to theoretically informative improvement research

Repeated calls have been made for the increased use of theory in designing and evaluating improvement and implementation interventions.1-4 The benefits are argued to include identifying contextual influences on quality improvement (QI), supporting the generalisability of findings and anticipating how future phenomena might unfold.2 5 Most importantly, the ability of

Explaining organisational responses to a board-level quality improvement intervention: findings from an evaluation in six providers in the English National Health Service

Background Healthcare systems worldwide are concerned with strengthening board-level governance of quality. We applied Lozeau, Langley and Denis’ typology (transformation, customisation, loose coupling and corruption) to describe and explain the organisational response to an improvement intervention in six hospital boards in England.

Complications following hip or knee surgery are more likely for people with long-term illness, but benefits are still worthwhile

The work of CLAHRC researcher Dr Bélène Podmore has been highlighted as “high quality” by the National Institute for Health Research. Bélène’s work, recently published in BMJ Open investigated how having a long-term condition impacts access to and benefit from hip and knee surgery. The research was promoted by NIHR via their “Signals” service. NIHR Signals summarise the latest important research on health care, public health and social care, along with implications for practice.

Joint replacement benefits and harms for people with other illness

Why was this study needed? In the UK, over 210,000 hip and knee replacements were performed in 2017 at an average age of 68 for hips and 69 for knees. One in six of these people had an illness affecting their day to day life.

Capturing the views of patients in emergency care

CLAHRC researchers highlight potential to use patient-reported outcomes for emergency admissions.

Patient-reported outcome measures or PROMs are a well-established method of capturing the views of NHS patients, allowing the service to assess the quality of care delivered, from the patient perspective.

PROMs use pre- and post-operative surveys completed by patients to calculate their health gains after surgical treatment.

While there is an extensive PROM programme across the English NHS, they have yet to be used in emergency admissions. These account for nearly 40% of all hospital admissions and are an area of increasing demand. However, this is also an area where the NHS knows least about;

  • the quality of patient outcomes,
  • whether resources are being used effectively,
  • and whether there are unexpected variation between different providers

CLAHRC researcher and PhD Dr Esther Kwong investigated how to use PROMs to evaluate the quality of acute and emergency hospital care in the NHS. Esther developed and tested PROMS with patients who underwent emergency admissions, establishing that it is feasible to use PROMS in this clinical area.

They are presented in four new CLAHRC BITEs – postcard summaries of Esther’s published academic papers.
