Evaluating the perceived impact and legacy of master's degree level research in the allied health professions: a UK-wide cross-sectional survey.

BACKGROUND: Post graduate master's degree qualifications are increasingly required to advance allied health profession careers in education, clinical practice, leadership, and research. Successful awards are dependent on completion of a research dissertation project. Despite the high volume of experience gained and research undertaken at this level, the benefits and impact are not well understood. Our study aimed to evaluate the perceived impact and legacy of master's degree training and research on allied health profession practice and research activity. METHODS: A cross-sectional online survey design was used to collect data from allied health professionals working in the United Kingdom who had completed a postgraduate master's degree. Participants were recruited voluntarily using social media and clinical interest group advertisement. Data was collected between October and December 2022 and was analysed using descriptive statistics and narrative content analysis. Informed consent was gained, and the study was approved by the university research ethics committee. RESULTS: Eighty-four responses were received from nine allied health professions with paramedics and physiotherapists forming the majority (57%) of respondents. Primary motivation for completion of the master's degree was for clinical career progression (n = 44, 52.4%) and formation of the research dissertation question was predominantly sourced from individual ideas (n = 58, 69%). Formal research output was low with 27.4% (n = 23) of projects published in peer reviewed journal and a third of projects reporting no output or dissemination at all. Perceived impact was rated highest in individual learning outcomes, such as improving confidence and capability in clinical practice and research skills. Ongoing research engagement and activity was high with over two thirds (n = 57, 67.9%) involved in formal research projects. CONCLUSION: The focus of master's degree level research was largely self-generated with the highest perceived impact on individual outcomes rather than broader clinical service and organisation influence. Formal output from master's research was low, but ongoing research engagement and activity was high suggesting master's degree training is an under-recognised source for AHP research capacity building. Future research should investigate the potential benefits of better coordinated and prioritised research at master's degree level on professional and organisational impact.

The effectiveness of prehabilitation interventions on biopsychosocial and service outcomes pre and post upper gastrointestinal surgery: a systematic review.

PURPOSE: This review synthesised the evidence for the effect of prehabilitation interventions on biopsychosocial and service outcomes. MATERIALS AND METHODS: A systematic review was conducted. 10 databases were searched to December 2023. Prospective experimental studies exploring prehabilitation interventions in adults undergoing upper gastrointestinal surgery were included. Prehabilitation was any preoperative intervention to improve physical or psychological outcomes. Included studies required a comparator group or alternative preoperative intervention as well as baseline, presurgical and postoperative assessment points. Study quality was assessed using the Cochrane risk of bias tool (v.2). Data synthesis was narrative (SWiM guidance). RESULTS: 6028 studies were screened, with 25 studies included. Prehabilitation interventions were: inspiratory muscle training (five studies n = 450); exercise (nine studies n = 683); psychological (one study n = 400); and nutritional (ten studies n = 487). High quality studies showed preoperative improvements in impairments directly targeted by the interventions. Generally, these did not translate into functional or postoperative improvements, but multimodal interventions were more promising. CONCLUSION: Current evidence supports prehabilitation as safe to preserve or improve preoperative function. Heterogeneity in outcomes and variable study quality means definitive conclusions regarding interventions are not yet possible, limiting implementation. Agreement of clinical outcomes and cost effectiveness evaluation is required.

Prehabilitation interventions are safe and when combined optimally may preserve or improve preoperative function in patients undergoing upper gastrointestinal surgery.Multimodal interventions (including exercise, nutritional, and psychological components) showed promise which supports the delivery of prehabilitation by multidisciplinary teams.Development of a core outcome set and agreed time points for both preoperative and postoperative outcomes is needed for effective evidence synthesis.Focus on long term outcomes is necessary to determine cost effectiveness and commissioning of resources.

Does the level of mobility on ICU discharge impact post-ICU outcomes? A retrospective analysis.

PURPOSE: Mobilisation is a common intervention in Intensive Care (ICU). However, few studies have explored the relationship between mobility levels and outcomes. This study assessed the association of the level of mobility on ICU discharge with discharge destination from the hospital and hospital length of stay. MATERIALS AND METHODS: A retrospective analysis of data from 522 patients admitted to a single UK general ICU who were ventilated for ≥5 days was performed. The level of mobility was assessed using the Manchester Mobility Score (MMS). Multivariable regression analysed demographic and clinical variables for the independence of association with discharge destination and hospital length of stay. RESULTS: MMS ≥5 on ICU discharge was independently associated with discharge destination and hospital LOS (p < 0.001). Patients achieving MMS ≥5 on ICU discharge were more likely to be discharged home (OR 3.86 95% CI 2.1 to 6.9, p < 0.001), and had an 11.8 day shorter hospital LOS (95% CI -17.6 to -6.1, p < 0.001). CONCLUSIONS: The ability to step transfer to a chair (MMS ≥5) before ICU discharge was independently associated with discharge to usual residence and hospital LOS, irrespective of preadmission morbidity. Increasing the level of patient mobility at ICU discharge should be a key focus of rehabilitation interventions.

Mobilisation in the Intensive Care Unit (ICU) is common practice, however studies to date have not evaluated the impact on acute hospital outcomes.Achieving the ability to step to a chair on ICU discharge is an important rehabilitation milestone, and is associated with a shorter hospital length of stay and being discharged home.Rehabilitation interventions in the ICU should be targeted at progressing patients towards this milestone.

Exploring individual character traits and behaviours of clinical academic allied health professionals: a qualitative study.

BACKGROUND: Clinical academic allied health professionals can positively impact patient care, organisational performance, and local research culture. Despite a previous national drive to increase these roles, they remain low in number with no clear strategy for growth. Reported barriers to this growth cite organisational and economic factors with little recognition of the challenges posed to individuals. There is a lack of research to help allied health professionals understand the personal challenges of clinical academic training and practice. The aim of this study is to explore the character traits and behaviours of clinical academic allied health professionals to understand the individual attributes and strategies taken to pursue a career in this field. METHODS: A semi-structured interview study design was used to collect data from aspiring and established clinical academic allied health professionals. Participants were recruited voluntarily through social media advertisement (aspiring) and purposively through direct email invitation (established). Participants were asked about their experience of pursuing a clinical academic career. The interviews were conducted virtually using Zoom and were audio recorded. The data were transcribed verbatim prior to reflexive thematic analysis. Informed consent was gained prior to data collection and the study was approved by the university's research ethics committee. RESULTS: Twenty participants from six allied health professions were interviewed. We developed five themes: risk and reward, don't wait to be invited, shifting motivations, research is a team sport, and staying the course. Clinical academic allied health professionals demonstrated traits including inquisitiveness, intuition, motivation, and resilience. The source of their motivation was rooted in improving clinical services, conducting research, and personal achievement. CONCLUSION: Clinical academic allied health professionals describe personal traits of high inquisitiveness, opportunism, motivation, and determination in pursuing their career ambitions. The tolerance of rejection, failure, and risk was considered important and viewed as an essential source for learning and professional development. Future research should concentrate on ways to reduce the over-reliance on individual strength of character to succeed in this field and explore programmes to increase the preparedness and support for clinical academics from these professions.

Musculoskeletal impairments after critical illness: A protocol for a qualitative study of the experiences of patients, family and health care professionals.

BACKGROUND: Survivors of critical care are at risk of long-term disability from musculoskeletal (MSK) impairments. These can have a biopsychosocial impact on the patient and their families with a reduction in health-related quality of life, increased health care utilization, caregiving roles and associated psychological distress. AIMS: To understand the experiences of patients living with MSK impairments following critical illness, and family and health care professionals supporting them, to inform the development of a future intervention to improve MSK health following critical illness. STUDY DESIGN: A four-site qualitative case study approach will be taken, with each of the four hospital sites and associated community services representing a case site. We will conduct semi-structured interviews with 10-15 patients/family members and 10-15 health care professionals about their experiences of MSK impairment following critical illness. Interviews will be audio recorded, transcribed verbatim and analysed using reflexive thematic analysis within a descriptive phenomenological approach. Alongside interview data, analysis of publicly available policy documentation, patient-facing materials and information from service leads at the four sites will be conducted. Discourse analysis will be used for this case study documentation. RESULTS: This protocol describes a qualitative study exploring the experiences of patients living with MSK impairments following critical illness, and the family and health care professionals supporting them. RELEVANCE TO CLINICAL PRACTICE: Data analysis will illuminate their experiences and enable data richness to contribute to the qualitative body of evidence of intensive care unit (ICU) survivors. These findings will inform the development of a complex intervention for MSK rehabilitation after critical illness.

Mobilisation in the EveNing to prevent and TreAt deLirium (MENTAL): a mixed-methods, randomised controlled feasibility trial.

Background: Delirium is common in critically ill patients and associated with longer hospital stays, increased morbidity and higher healthcare costs. Non-pharmacological interventions have been advocated for delirium management, however there is little evidence evaluating feasibility and acceptability of physical interventions administered in the evening. The aim of this study was to conduct a feasibility trial of evening mobilisation to prevent and treat delirium in patients admitted to intensive care. Methods: In this mixed-methods, randomised controlled feasibility trial we recruited participants from intensive care units at two university hospitals in the United Kingdom. Eligible participants who were able to respond to verbal stimulus (Richmond agitation and sedation scale ≥3) and expected to stay in intensive care for at least 24 h were randomly assigned (1:1) to receive usual care or usual care plus evening mobilisation. The evening mobilisation was delivered between 19:00 and 21:00, for up to seven consecutive evenings or ICU discharge, whichever was sooner. All outcome assessments were completed by a team member blinded to randomisation and group allocation. Primary objective was to assess feasibility and acceptability of evening mobilisation. Primary feasibility outcomes were recruitment, consent and retention rates, and intervention fidelity. Intervention acceptability was evaluated through semi-structured interviews of participants and staff. Secondary outcomes included prevalence in incidence and duration of delirium, measured using the Confusion Assessment Method for ICU. This trial is registered at ClinicalTrials.gov, NCT05401461. Findings: Between July 16th, 2022, and October 31st, 2022, 58 eligible patients (29 usual care; 29 usual care plus evening mobilisation) were enrolled. We demonstrated the feasibility and acceptability of both the trial design and evening mobilisation intervention. Consent and retention rates over three months were 88% (58/66) and 90% (52/58) respectively, with qualitative analysis demonstrating good acceptability reported by both participants and staff. Secondary outcomes for the evening intervention group compared with the control group were: delirium incidence 5/26 (19%; 95% CI: 6-39%) vs 8/28 (29%; 95% CI: 13-49%) and mean delirium duration 2 days (SD 0.7) vs 4.25 days (SD 2.0). Interpretation: Results of this trial will inform the development of a definitive full-scale randomised controlled trial investigating the effects of evening mobilisation to treat delirium and improve health-related outcomes. Funding: None.

Allied health professionals' research capacity: open to interpretation?

Allied health professional research capacity and culture has been the focus of growing research interest of late. The recent study by Comer et al. represents the largest survey of allied health research capacity and culture to date. We congratulate the authors on this work and would like to raise some discussion points in relation to their study.The authors have interpreted their research capacity and culture survey results using cut-off values to indicate a degree of adequacy in relation to perceived research success and/or skill level. To our knowledge, the constructs of the research capacity and culture tool have not been validated to an extent that would enable such an inference to be made.Comer et al. describe perceived individual research success and/or skill as adequate, but the rating of skills in areas necessary for the conduct of original research, such as writing research protocols, ethics submissions, securing funding, and writing for publication range from median scores one to three, which is considered 'less than adequate' on the interpretation scale used by the authors.The survey results for the individual and organisational domains reported in Comer et al. are comparable to other similar studies. However, they uniquely conclude research success and/or skill to be adequate in both domains, which is contrary to the interpretation of the other studies.The interpretation of allied health professional research success and skill offered by Cromer et al. differs from studies with similar results and is contrary to previous reports of insufficient research capacity in terms of research trained and active practitioners within these professions in the UK.

Building a Covid-19 secure intensive care unit: A human-centred design approach.

Background: The Covid-19 pandemic has highlighted weaknesses in the National Health Service critical care provision including both capacity and infrastructure. Traditionally, healthcare workspaces have failed to fully incorporate Human-Centred Design principles resulting in environments that negatively affect the efficacy of task completion, patient safety and staff wellbeing. In the summer of 2020, we received funds for the urgent construction of a Covid-19 secure critical care facility. The aim of this project was to design a pandemic resilient facility centred around both staff and patient requirements and safety, within the available footprint. Methods: We developed a simulation exercise, underpinned by Human-Centred Design principles, to evaluate intensive care designs through Build Mapping, Tasks Analysis and Qualitative data. Build Mapping involved taping out sections of the design and mocking up with equipment. Task Analysis and qualitative data were collected following task completion. Results: 56 participants completed the build simulation exercise generating 141 design suggestions (69 task related, 56 patient and relative related, 16 staff related). Suggestions translated to 18 multilevel design improvements; five significant structural changes (Macro level) including wall moves and lift size change. Minor improvements were made at a Meso and Micro design level. Critical care design drivers identified included functional drivers (visibility, Covid-19 secure environment, workflow, and task efficiency) and behavioural drivers (learning and development, light, humanising intensive care and design consistency). Conclusion: Success of clinical tasks, infection control, patient safety and staff/patient wellbeing are highly dependent on clinical environments. Primarily, we have improved clinical design by focusing on user requirements. Secondly, we developed a replicable approach to exploring healthcare build plans revealing significant design changes, that may have only been identified once built.

Investigating the impact of physical activity interventions on delirium outcomes in intensive care unit patients: A systematic review and meta-analysis.

Background: To investigate the impact of physical activity interventions, including early mobilisation, on delirium outcomes in critically ill patients. Methods: Electronic database literature searches were conducted, and studies were selected based on pre-specified eligibility criteria. Cochrane Risk of Bias-2 and Risk Of Bias In Non-randomised Studies-of Interventions quality assessment tools were utilised. Grading of Recommendations, Assessment, Development and Evaluations was used to assess levels of evidence for delirium outcomes. The study was prospectively registered on PROSPERO (CRD42020210872). Results: Twelve studies were included; ten randomised controlled trials one observational case-matched study and one before-after quality improvement study. Only five of the included randomised controlled trial studies were judged to be at low risk of bias, with all others, including both non-randomised controlled trials deemed to be at high or moderate risk. The pooled relative risk for incidence was 0.85 (0.62-1.17) which was not statistically significant in favour of physical activity interventions. Narrative synthesis for effect on duration of delirium found favour towards physical activity interventions reducing delirium duration with median differences ranging from 0 to 2 days in three comparative studies. Studies comparing varying intervention intensities showed positive outcomes in favour of greater intensity. Overall levels of evidence were low quality. Conclusions: Currently there is insufficient evidence to recommend physical activity as a stand-alone intervention to reduce delirium in Intensive Care Units. Physical activity intervention intensity may impact on delirium outcomes, but a lack of high-quality studies limits the current evidence base.

Mobilisation in the EveNing to TreAt deLirium (MENTAL): protocol for a mixed-methods feasibility randomised controlled trial.

INTRODUCTION: Delirium is common in critically ill patients and is associated with longer hospital stays, increased mortality and higher healthcare costs. A number of risk factors have been identified for the development of delirium in intensive care, two of which are sleep disturbance and immobilisation. Non-pharmacological interventions for the management of intensive care unit (ICU) delirium have been advocated, including sleep protocols and early mobilisation. However, there is a little published evidence evaluating the feasibility and acceptability of evening mobilisation. METHODS AND ANALYSIS: Mobilisation in the EveNing to TreAt deLirium (MENTAL) is a two-centre, mixed-methods feasibility randomised controlled trial (RCT). Sixty patients will be recruited from ICUs at two acute NHS trusts and randomised on a 1:1 basis to receive additional evening mobilisation, delivered between 19:00 and 21:00, or standard care. The underpinning hypothesis is that the physical exertion associated with evening mobilisation will promote better sleep, subsequently having the potential to reduce delirium incidence. The primary objective is to assess the feasibility and acceptability of a future, multicentre RCT. The primary outcome measures, which will determine feasibility, are recruitment and retention rates, and intervention fidelity. Acceptability of the intervention will be evaluated through semi-structured interviews of participants and staff. Secondary outcome measures include collecting baseline, clinical and outcome data to inform the power calculations of a future definitive trial. ETHICS AND DISSEMINATION: Ethical approval has been obtained through the Wales Research and Ethics Committee 6 (22/WA/0106). Participants are required to provide written informed consent. We aim to disseminate the findings through international conferences, international peer-reviewed journals and social media. TRIAL REGISTRATION NUMBER: NCT05401461.

Musculoskeletal health state and physical function of intensive care unit survivors: protocol for a UK multicentre prospective cohort study (the MSK-ICU study).

INTRODUCTION: Survivors of critical illness frequently experience long-term physical impairment, decreased health-related quality of life and low rates of return to employment. There has been limited investigation of the underlying problems affecting physical function post-intensive care unit (ICU) admission. Musculoskeletal (MSK) conditions may be complex in presentation, with ICU survivors potentially at greater risk of their development due to the rapid muscle mass loss seen in ICU. The MSK health state of ICU survivors and its impact on physical function remain largely unknown. The aim of the MSK-ICU study is to determine and characterise the MSK health state of ICU survivors 6 months following admission to ICU, in order to inform development of targeted rehabilitation interventions. METHODS AND ANALYSIS: The MSK-ICU study is a multicentre prospective longitudinal cohort study, evaluating the MSK health state of ICU survivors 6 months after admission to ICU. The study consists of a primary study and two substudies. The primary study will be a telephone follow-up of adults admitted to ICU for more than 48 hours, collecting data on MSK health state, quality of life, employment, anxiety and depression and symptoms of post-traumatic stress disorder. The planned sample size is 334 participants. Multivariable regression will be used to identify prognostic factors for a worse MSK health state, as measured by the MSK-Health Questionnaire. In substudy 1, participants who self-report any MSK problem will undergo a detailed, in-person MSK physical assessment of pain, peripheral joint range of movement and strength. In substudy 2, participants reporting a severe MSK problem will undergo a detailed physical assessment of mobility, function and muscle architecture. ETHICS AND DISSEMINATION: Ethical approval has been obtained through the North of Scotland Research Ethics Committee 2 (21/NS/0143). We aim to disseminate the findings through international conferences, international peer-reviewed journals and social media. TRIAL REGISTRATION NUMBER: ISRCTN24998809.

Multidisciplinary team perception of games-based therapy in critical care: A service evaluation.

BACKGROUND: As survivorship following critical illness improves, there is greater focus on maximizing recovery. As well as physical effects, critical illness often results in cognitive impairments such as delirium, anxiety, or disorientation. In other populations, such as delirium, non-pharmacological approaches to manage these conditions are preferred, including re-orientation and ensuring personal care needs are met. Cognitive rehabilitation is also well documented for patients with neuropsychological deficits. Treatments include memory aids, compensation strategies, and functional execution. In other hospital populations, games and activities have been utilized to optimize patient engagement, stimulation, and aid recovery, but it is considered an emerging therapy in intensive care. AIMS: This service evaluation aimed to gather multidisciplinary team members' perceptions of the use of games based therapy (GBT) in critical care, including patient engagement and acceptability in clinical practice. STUDY DESIGN: A UK-based single-centre qualitative service evaluation. Purposive sampling was used to identify interviewees within an adult intensive care who had experience of using a recently implemented GBT intervention. Qualitative data were collected through semi-structured interviews, which were recorded and transcribed verbatim. Data were analysed using thematic analysis. RESULTS: Eight staff members across the multidisciplinary team were interviewed. One overarching theme of humanizing health care was identified, with three sub-themes of enhancing recovery, non-physical components of care, and bespoke tailoring. In addition, further recommendations for development of the service were summarized. CONCLUSION: GBT was well received by staff in clinical practice. It was described as a supportive adjunct to traditional care and rehabilitation, enhancing staff-patient relationships. While it was recognized it may not suit all patients, GBT has the potential to enhance cognitive and physical recovery.

The effects of inspiratory muscle training on inspiratory muscle strength, lung function and quality of life in adults with spinal cord injuries: a systematic review and Meta-analysis.

PURPOSE: This systematic review and meta-analysis aimed to evaluate the effectiveness of inspiratory muscle training (IMT) on respiratory muscle strength, lung function and quality of life (QOL) in adults with spinal cord injuries (SCI). METHODS: Databases were searched up to June 2022; CENTRAL, CINAHL, MEDLINE, PEDRo, and PubMed. Following PRISMA reporting guidelines, two independent reviewers selected studies and extracted data. Study quality and levels of evidence were assessed. RESULTS: Following selection from 624 initial search results, six randomised controlled trials were identified, comprising 124 participants. Quality of Evidence was very low to moderate. Meta-analysis showed that post intervention, IMT significantly improved maximal inspiratory pressure (MD 15.72 cmH2O, 95% CI 5.02, 26.41, p = 0.004) when compared with a control intervention. There was no significant benefit for physical QOL (SMD 0.12, 95% CI -1.01, 1.25, p = 0.84), mental QOL (SMD -0.2, 95% CI -1.72, 1.33, p = 0.80), maximal expiratory pressure (MD 5.19 cmH2O, 95% CI -4.16, 14.55, p = 0.80), or FEV1 (MD 0.26 L, 95% CI -0.19, 0.7, p = 0.26). Sensitivity analyses found larger effects for studies with 8 week interventions (MD 17.5 cmH2O (95% CI 3.36 to 31.66)) and spring loaded devices alone (MD 21.18 cmH2O, 95% CI 9.65 to 32.72). CONCLUSION: Moderate quality evidence suggests IMT improves respiratory strength in adults with an SCI. The mental and physical QOL outcomes provided very low quality of evidence, with considerable heterogeneity between study results, leading to inconsistency. Further research is warranted to investigate medium and long-term impact of robust IMT protocols, accounting for patient motivation and adherence to IMT.IMPLICATIONS FOR REHABILITATIONInspiratory muscle training (IMT) significantly improves respiratory muscle strength in adults with spinal cord injuries-irrespective of time since injury, or degree of injury completeness.IMT is a feasible, safe, and worthwhile intervention to implement with adults with spinal cord injuries and can be utilized in a variety of settings.IMT interventions that are 8 weeks long and utilize a spring-loaded inspiratory threshold device may generate the largest improvements in respiratory strength.

Patient Harm and Institutional Avoidability of Out-of-Hours Discharge From Intensive Care: An Analysis Using Mixed Methods.

OBJECTIVES: Out-of-hours discharge from ICU to the ward is associated with increased in-hospital mortality and ICU readmission. Little is known about why this occurs. We map the discharge process and describe the consequences of out-of-hours discharge to inform practice changes to reduce the impact of discharge at night. DESIGN: This study was part of the REcovery FoLlowing intensive CarE Treatment mixed methods study. We defined out-of-hours discharge as 16:00 to 07:59 hours. We undertook 20 in-depth case record reviews where in-hospital death after ICU discharge had been judged "probably avoidable" in previous retrospective structured judgment reviews, and 20 where patients survived. We conducted semistructured interviews with 55 patients, family members, and staff with experience of ICU discharge processes. These, along with a stakeholder focus group, informed ICU discharge process mapping using the human factors-based functional analysis resonance method. SETTING: Three U.K. National Health Service hospitals, chosen to represent different hospital settings. SUBJECTS: Patients discharged from ICU, their families, and staff involved in their care. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Out-of-hours discharge was common. Patients and staff described out-of-hours discharge as unsafe due to a reduction in staffing and skill mix at night. Patients discharged out-of-hours were commonly discharged prematurely, had inadequate handover, were physiologically unstable, and did not have deterioration recognized or escalated appropriately. We identified five interdependent function keys to facilitating timely ICU discharge: multidisciplinary team decision for discharge, patient prepared for discharge, bed meeting, bed manager allocation of beds, and ward bed made available. CONCLUSIONS: We identified significant limitations in out-of-hours care provision following overnight discharge from ICU. Transfer to the ward before 16:00 should be facilitated where possible. Our work highlights changes to help make day time discharge more likely. Where discharge after 16:00 is unavoidable, support systems should be implemented to ensure the safety of patients discharged from ICU at night.

The Use of Wearable Pulse Oximeters in the Prompt Detection of Hypoxemia and During Movement: Diagnostic Accuracy Study.

BACKGROUND: Commercially available wearable (ambulatory) pulse oximeters have been recommended as a method for managing patients at risk of physiological deterioration, such as active patients with COVID-19 disease receiving care in hospital isolation rooms; however, their reliability in usual hospital settings is not known. OBJECTIVE: We report the performance of wearable pulse oximeters in a simulated clinical setting when challenged by motion and low levels of arterial blood oxygen saturation (SaO2). METHODS: The performance of 1 wrist-worn (Wavelet) and 3 finger-worn (CheckMe O2+, AP-20, and WristOx2 3150) wearable, wireless transmission-mode pulse oximeters was evaluated. For this, 7 motion tasks were performed: at rest, sit-to-stand, tapping, rubbing, drinking, turning pages, and using a tablet. Hypoxia exposure followed, in which inspired gases were adjusted to achieve decreasing SaO2 levels at 100%, 95%, 90%, 87%, 85%, 83%, and 80%. Peripheral oxygen saturation (SpO2) estimates were compared with simultaneous SaO2 samples to calculate the root-mean-square error (RMSE). The area under the receiver operating characteristic curve was used to analyze the detection of hypoxemia (ie, SaO2<90%). RESULTS: SpO2 estimates matching 215 SaO2 samples in both study phases, from 33 participants, were analyzed. Tapping, rubbing, turning pages, and using a tablet degraded SpO2 estimation (RMSE>4% for at least 1 device). All finger-worn pulse oximeters detected hypoxemia, with an overall sensitivity of ≥0.87 and specificity of ≥0.80, comparable to that of the Philips MX450 pulse oximeter. CONCLUSIONS: The SpO2 accuracy of wearable finger-worn pulse oximeters was within that required by the International Organization for Standardization guidelines. Performance was degraded by motion, but all pulse oximeters could detect hypoxemia. Our findings support the use of wearable, wireless transmission-mode pulse oximeters to detect the onset of clinical deterioration in hospital settings.

Exploring research capacity and culture of allied health professionals: a mixed methods evaluation.

BACKGROUND: Despite the myriad benefits of research to patients, professionals, and organisations, fewer than 0.1% of the Allied Health Professions workforce are employed in clinical academic roles. Identified barriers include a lack of role modelling, management support, funding, and availability of clinical academic roles. Research capacity building is critical to improving Allied Health Professional research capability. The aim of this evaluation was to explore the current research capacity and culture of Allied Health Professionals to inform future tailored research capacity building strategies at a local level. METHODS: A mixed methods evaluation of research capacity and culture was conducted within the Allied Health Professions department of a large National Health Service Foundation Trust using an online research capacity and culture questionnaire, followed by focus groups. Staff were recruited using a purposive method with the questionnaire and subsequent focus groups completed between July and September 2020. Data from the questionnaire was analysed using simple descriptive statistics and after inductive coding, focus group data was analysed thematically. RESULTS: 93 out of 278 staff completed the questionnaire and 60 staff members attended seven focus groups. The research capacity and culture survey reported the department's key strength as promoting clinical practice based on evidence (median=8, range=6-9). A key reported weakness of the department was insufficient resources to support staff research training (med=4, 3-6). Respondents considered themselves most skilled in finding relevant literature (med=6, 5-8) and least skilled at securing research funding (med=1, 1-2). Greater than half of the respondents (n=50) reported not currently being involved with research. Five themes were identified from the focus groups: empowerment; building research infrastructure; fostering research skills; access for all; and positive research culture. CONCLUSIONS: Allied Health Professionals recognise the benefits of research at teams and departmental level, but marginally at an individual level. Local research capacity building strategies should aim to address the role, responsibilities and barriers to Allied Health Profession research development at an individual level. To ensure all staff can engage, research infrastructure and empowerment are essential.

A Chest Patch for Continuous Vital Sign Monitoring: Clinical Validation Study During Movement and Controlled Hypoxia.

BACKGROUND: The standard of care in general wards includes periodic manual measurements, with the data entered into track-and-trigger charts, either on paper or electronically. Wearable devices may support health care staff, improve patient safety, and promote early deterioration detection in the interval between periodic measurements. However, regulatory standards for ambulatory cardiac monitors estimating heart rate (HR) and respiratory rate (RR) do not specify performance criteria during patient movement or clinical conditions in which the patient's oxygen saturation varies. Therefore, further validation is required before clinical implementation and deployment of any wearable system that provides continuous vital sign measurements. OBJECTIVE: The objective of this study is to determine the agreement between a chest-worn patch (VitalPatch) and a gold standard reference device for HR and RR measurements during movement and gradual desaturation (modeling a hypoxic episode) in a controlled environment. METHODS: After the VitalPatch and gold standard devices (Philips MX450) were applied, participants performed different movements in seven consecutive stages: at rest, sit-to-stand, tapping, rubbing, drinking, turning pages, and using a tablet. Hypoxia was then induced, and the participants' oxygen saturation gradually reduced to 80% in a controlled environment. The primary outcome measure was accuracy, defined as the mean absolute error (MAE) of the VitalPatch estimates when compared with HR and RR gold standards (3-lead electrocardiography and capnography, respectively). We defined these as clinically acceptable if the rates were within 5 beats per minute for HR and 3 respirations per minute (rpm) for RR. RESULTS: Complete data sets were acquired for 29 participants. In the movement phase, the HR estimates were within prespecified limits for all movements. For RR, estimates were also within the acceptable range, with the exception of the sit-to-stand and turning page movements, showing an MAE of 3.05 (95% CI 2.48-3.58) rpm and 3.45 (95% CI 2.71-4.11) rpm, respectively. For the hypoxia phase, both HR and RR estimates were within limits, with an overall MAE of 0.72 (95% CI 0.66-0.78) beats per minute and 1.89 (95% CI 1.75-2.03) rpm, respectively. There were no significant differences in the accuracy of HR and RR estimations between normoxia (≥90%), mild (89.9%-85%), and severe hypoxia (<85%). CONCLUSIONS: The VitalPatch was highly accurate throughout both the movement and hypoxia phases of the study, except for RR estimation during the two types of movements. This study demonstrated that VitalPatch can be safely tested in clinical environments to support earlier detection of cardiorespiratory deterioration.

Musculoskeletal complications following critical illness: A scoping review.

PURPOSE: To explore the extent to which musculoskeletal (MSK) complications have been reported following critical illness, identifying evidence gaps and providing recommendations for future research. MATERIALS AND METHODS: We searched five databases from January 1st 2000 to March 31st 2021. We included published original research reporting MSK complications in patients discharged from hospital following an admission to an intensive care unit (ICU). Two reviewers independently screened English language articles for eligibility. Data extracted included the MSK area of investigation and MSK outcome measures. The overall quality of study was evaluated against standardised reporting guidelines. RESULTS: 4512 titles were screened, and 32 met the inclusion criteria. Only one study included was interventional, with the majority being prospective cohort studies (n = 22). MSK complications identified included: muscle weakness or atrophy, chronic pain, neuromuscular dysfunction, peripheral joint impairment and fracture risk. The quality of the overall reporting in the studies was deemed adequate. CONCLUSIONS: We identified a heterogenous body of literature reporting a high prevalence of a variety of MSK complications extending beyond muscle weakness, therefore future investigation should include evaluations of more than one MSK area. Further investigation of MSK complications could inform the development of future post critical illness rehabilitation programs.
