Objectives

To identify and prioritise research uncertainties regarding the assessment, management and rehabilitation of patients with problematic hip replacements through a national Priority Setting Partnership (PSP).

Design

A national PSP using the James Lind Alliance (JLA) methodology.

Setting

UK.

Participants

Patients, carers and healthcare professionals (HCPs) involved in the care of patients with problematic hip replacements.

Methods

A steering group was established. The James Lind Alliance methodology was followed throughout. A nationwide survey was conducted to collect unanswered questions. These were refined, prioritised through an interim survey and ranked at a final consensus workshop.

Results

The initial survey yielded 201 questions, refined to 32. The interim survey had 191 respondents, leading to 19 questions at the final workshop. The top 10 research priorities were agreed on.

Conclusions

This PSP identified key research priorities for problematic hip replacements, focusing on diagnosis, pain management, perioperative optimisation and infection. These priorities can inform researchers and funders to improve outcomes for affected patients.

Association between hospital frailty risk score, risk of sepsis and adverse outcomes across all adult ages

by Huda Kutrani, Jim Briggs, David Prytherch, Claire Spice

Background

Hospital Frailty Risk Score (HFRS) is commonly used to identify frailty risk and predict poor outcomes. Frailty and sepsis are associated with poor outcomes. This study aimed to evaluate the association between HFRS, risk of sepsis and poor health outcomes across all adult ages.

Methods

A retrospective cohort study analysed data from Queen Alexandra Hospital, a major acute hospital in the UK, covering the period from January 1, 2010, to December 31, 2019. It included patients aged 16 and older. The Hospital Frailty Risk Score (HFRS) was used to identify patients at risk of frailty. The Suspicion of Sepsis (SOS) codes and the National Early Warning Score (NEWS) were used to identify patients at risk of sepsis. Logistic Regression with interaction models were developed to examine the associations between HFRS, risk of sepsis and poor outcomes (length of stay and in-hospital mortality) across all adult ages.

Results

Patients with higher frailty risk and sepsis-risk-positive groups had longer length of stay and higher risk of in-hospital mortality compared to the sepsis-risk-negative groups. Interaction between intermediate or high frailty risk and sepsis-risk-positive (SOS codes present, NEWS≥7, and SOS codes present with NEWS≥7 groups) was significant for all periods of length of stay and all periods of in-hospital mortality (P  Conclusion

This study concluded that there is a strong association between risk of frailty (identified with HFRS), risk of sepsis, and poor outcomes in urgently hospitalised adults of all ages.

Transcriptome profiling indicates varied gene responses to <i>Pasteurella multocida</i> mutant infections in cattle

by Hao Ma, Fred M. Tatum, Robert E. Briggs, Rohana P. Dassanayake, Tasia M. Kendrick, Eduardo Casas

Pasteurella multocida is a pathogen that causes bovine respiratory disease, and the development of an effective vaccine is important for improving animal health. Live-attenuated vaccines induce a long-lasting immune response with minimal side effects. The objective of this study was to evaluate potential live vaccine candidates from three P. multocida mutants produced by separately disrupting the genes of filamentous hemagglutinin 2 (fhaB2), hydrogenase-1 operon (hyaE), and n-acylneuraminate-9-phosphatase (nanP) of a serogroup 3 strain (P1062, WT) by clinical testing and transcriptome analysis. Challenge with WT and the three mutants conferred protection against P. multocida, with less lung lesions (4.7–6.2%) compared to 22.4% in the sham group. Transcriptome analysis identified 807 differentially expressed protein-coding transcripts (DETs) in the blood and 6473 DETs in the liver compared to the sham, WT, and each of the mutants. In total, 15 and 64 differentially expressed microRNAs (DEmiRNAs) and 12 and 74 differentially expressed long non-coding RNAs (DElncRNAs) were identified in blood and liver, respectively. The DEmiRNAs were not significantly associated with the DETs within each comparison. DElncRNAs were associated with 12 and 170 DETs in blood and liver respectively. The greatest number of unique DETs were found between hyaE and sham groups in the liver, which agreed with the low colonization rate in the nares and palatine tonsils. For the DETs between sham and WT the under-enriched gene ontology terms in blood were all included in the liver for the DETs identified by WT vs. sham, nanP vs. sham, and hyaE vs. sham, and were related to the signaling pathway, stimulus, and sensory perceptions in biological processes with the molecular function of olfactory receptor activity. The number of identified DETs, decreased percentage of lung lesions, and colonization rates indicate that fhaB2 could be a promising vaccine candidate.

Determining the burden of falls amongst community-dwelling older people in Ireland to inform falls care delivery: secondary data analysis from the Irish longitudinal study on ageing - the defined study

Por: Briggs · R. · Ward · M. · Scarlett · S. · van der Velde · N. · Hernandez · B. · Romero-Ortuno · R. · Tysinger · B. · May · P. · Ahern · E. · Kenny · R. A.
Objective

Falls represent the most frequent reason older people are admitted to hospital and significantly increase the likelihood of functional decline, healthcare utilisation and early mortality. The aim of this study is to comprehensively delineate the burden of falls amongst community-dwelling older people in Ireland.

Design

Population-representative analysis of Wave 6 of the Irish Longitudinal Study on Ageing (TILDA) estimating incidence of falls requiring medical attention and emergency department (ED) attendance, fractures and fear of falling over 12 months. Additional data detailing falls-risk increasing drugs (FRIDs) and prior falls were also analysed.

Using Central Statistics Office Census 2022, the population of older people in Ireland was multiplied by the proportion of TILDA participants with each outcome of interest to yield population-level estimates.

Participants/Setting

Population-representative sample of 2299 (55% female) community-dwelling people in Ireland aged ≥70 years.

Results

Almost 12% (proportion 0.12 (95% CI 0.10 to 0.13)) of participants, corresponding to almost 62 000 older people in Ireland, reported a fall requiring medical attention in 12 months, with 6% (proportion 0.06 (95% CI 0.05 to 0.07)), or over 32 000 people, attending ED due to a fall. Over 3% (proportion 0.03 (95% CI 0.03 to 0.04)) reported sustaining a fracture. Almost half of participants reporting a fall requiring medical attention were prescribed FRIDs, and over half had also reported a fall when assessed at the prior wave of the study (ie, 2 years ago).

Conclusions

The burden of falls amongst community-dwelling older people is considerable; 1 in 8 required medical attention for a fall and 1 in 16 attended the ED with falls over 12 months.

Currently, there is no national falls strategy in Ireland. These findings, alongside our ageing population, underscore the need for strengthened falls-prevention strategies to reduce avoidable morbidity and healthcare utilisation.

How prevalent are modifiable dementia risk factors in Ireland? A 12-year observational study in community-dwelling older adults

Por: McGarvey · C. · Kenny · R. A. · Kennelly · S. · Sexton · D. · Briggs · R.
Objectives

Dementia is potentially preventable and deferrable yet remains a major cause of disability, dependency and mortality worldwide. The 2024 Lancet Commission on dementia identified 14 modifiable dementia risk factors and estimated that addressing these could reduce dementia cases by up to 45%. The aim of this study is to assess dementia risk factor prevalence in adults ≥50 years participating in a nationally representative longitudinal study on ageing, providing crucial context for the delivery of dementia prevention.

Design and setting

The Irish Longitudinal Study on Ageing (TILDA) is a population-based prospective cohort study, representative of community-dwelling adults ≥50 years living in Ireland.

Participants

All participants from waves 1 (2009–2010): n=8171, 3 (2014–2015): n=6615 and 6 (2021–2023): n=4318 of TILDA were analysed over a 10.93 (±0.37) years of follow-up.

Results

70.6%, 61.1% and 54.2% of the population had ≥4 modifiable risk factors for dementia at consecutive waves, amounting to over 500 000 people with ≥4 modifiable risk factors for dementia on weighted population analysis at wave 6. 77% of those with severe decline in cognitive performance during follow-up had ≥4 risk factors at baseline. An estimated 32 480 cases of severe decline in cognitive performance during follow-up were potentially preventable if risk factors were addressed.

Conclusions

In a nationally representative sample of older European adults, there is a high prevalence of modifiable dementia risk factors. This highlights the need for greater attention on educating people on the concept of brain health through public health messaging as well as the development of a clinical framework focused on delivering on the opportunity of dementia prevention. Preventing and delaying dementia onset can have a significant impact on the compression of morbidity and increasing healthy lifespan in older age.

What is the experience of healthcare professionals managing Achilles tendon ruptures in the National Health Service (NHS)?--a qualitative interview study in the United Kingdom

Por: Briggs-Price · S. · Yates · T. · Mangwani · J. · Bhatia · M. · ONeill · S.
Objective

To explore National Health Service (NHS) healthcare professionals’ experiences of delivering rehabilitation for patients with Achilles tendon rupture (ATR).

Design

Qualitative study using semistructured interviews and reflexive thematic analysis.

Setting

NHS hospital sites in the United Kingdom, providing non-surgical ATR management using the Leicester Achilles Management Protocol (LAMP).

Participants

Twenty-one NHS healthcare professionals, including physiotherapists and orthopaedic consultants with a mean of 10.8 years of clinical experience, purposively sampled based on profession and experience managing ATR.

Results

Three main themes were identified: (1) clinical training on Achilles tendon ruptures, (2) rehabilitation following ATR and (3) the NHS service delivering rehabilitation. Participants reported limited training on ATR, leading to reduced confidence and slower rehabilitation progressions. Fear of re-injury influenced clinical decision-making, while discharge decisions were goal-oriented but constrained by service limitations.

Conclusions

This study highlights limited clinical training, inconsistent rehabilitation practices and NHS service constraints that collectively slow rehabilitation progress and affect return to sport following ATR. Enhanced training, service development and greater standardisation of ATR rehabilitation pathways are recommended to improve patient outcomes.

Clinical practice guidelines for the care of people experiencing chronic primary pain: protocol for a systematic review with interpretation against an established chronic pain care priority framework

Por: Briggs · A. M. · Siegfried · N. · Waller · R. · OConnell · N. E. · Romero · L. · Klem · N.-R. · Ampiah · P. K. · Belton · J. L. · Blyth · F. M. · De Morgan · S. · Lord · S. M. · Nicholas · M. · OSullivan · P. B. · Shakya · A. · Smith · A. J. · Slater · H.
Introduction

Most clinical practice guidelines (CPGs) for assessing and managing people’s chronic pain focus on specific pain conditions, body sites or life course stages. This creates complexity for clinicians making care choices in the absence of a diagnosis and/or where a person experiences more than one pain condition. Specific to this context is the ICD-11 classification of chronic primary pain where an experience of pain cannot be better accounted for by another condition. CPGs for chronic primary pain, agnostic to condition or body part, may support clinicians towards best pain care since many of the principles of person-centred chronic pain care are transdiagnostic. The two aims of this systematic review are to (1) identify and appraise CPGs for chronic primary pain, relevant across the life course and (2) map the CPG content against a pain care priority framework to evaluate the extent to which the CPG content aligns with the priorities of people with lived chronic pain experience.

Methods and analysis

We will systematically search nine scholarly databases, the Epistemonikos database and international and national guidelines clearinghouses. CPGs published within 2015–2025, in any language, that offer recommendations about assessment and/or management of chronic primary pain for people of any age, excluding hospitalised inpatients or institutionalised populations, will be included. Pairs of reviewers will independently screen citations for eligibility and appraise CPG quality and implementation potential using the Appraisal of Guidelines for Research and Evaluation (AGREE)-II and the AGREE-Recommendations Excellence tools, respectively. Data extraction will include the citation and scope characteristics of each CPG, methods used to develop recommendations, verbatim recommendations, guiding principles or practice information and narrative excerpts related to the GRADE Evidence-to-Decision (EtD) considerations (or equivalent). We will use the PROGRESS-PLUS framework as a checklist to identify whether determinants of health equity were considered by guideline developers. CPG recommendations will be organised according to common topics and categorised in a matrix according to strength and direction. Qualitative content analysis will be used to synthesise excerpts relating to GRADE EtD considerations (or equivalent), and we will map extracted data against an established chronic pain care priority framework to determine the extent to which the CPGs align with values and preferences of people with lived experience. Interpretation will be informed by an interdisciplinary Advisory Group, including lived experience partners.

Ethics and dissemination

Ethical approval is not required for this systematic review. Results will be disseminated through publication in an open-access peer-reviewed journal, through professional societies, and integrated into education curricula and public-facing resources. Reporting will be consistent with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement.
