Quality of life support in advanced cancer-web and technological interventions: systematic review and narrative synthesis.

BACKGROUND: As treatments continue to progress, patients with advanced cancer are living longer. However, ongoing physical side-effects and psychosocial concerns can compromise quality of life (QoL). Patients and physicians increasingly look to the internet and other technologies to address diverse supportive needs encountered across this evolving cancer trajectory. OBJECTIVES: 1. To examine the features and delivery of web and technological interventions supporting patients with advanced cancer. 2. To explore their efficacy relating to QoL and psychosocial well-being. METHODS: Relevant studies were identified through electronic database searches (MEDLINE, PsychINFO, Embase, CINAHL, CENTRAL, Web of Science and ProQuest) and handsearching. Findings were collated and explored through narrative synthesis. RESULTS: Of 5274 identified records, 37 articles were included. Interventions were evaluated within studies targeting advanced cancer (13) or encompassing all stages (24). Five subtypes emerged: Interactive Health Communication Applications (n=12), virtual programmes of support (n=11), symptom monitoring tools (n=8), communication conduits (n=3) and information websites (n=3). Modes of delivery ranged from self-management to clinically integrated. Support largely targeted psychosocial well-being, alongside symptom management and healthy living. Most studies (78%) evidenced varying degrees of efficacy through QoL and psychosocial measures. Intervention complexity made it challenging to distinguish the most effective components. Incomplete reporting limited risk of bias assessment. CONCLUSION: While complex and varied in their content, features and delivery, most interventions led to improvements in QoL or psychosocial well-being across the cancer trajectory. Ongoing development and evaluation of such innovations should specifically target patients requiring longer-term support for later-stage cancer. PROSPERO REGISTRATION NUMBER: CRD42018089153.

Clinical and microbiological investigation into mixed growth urine cultures.

Introduction. Urine samples submitted for investigation of urinary tract infection (UTI) may identify more than one bacterial isolate. These samples may be reported as 'mixed growth urine culture' (MGUC). The clinical significance of MGUC remains controversial.Hypothesis/Gap Statement. The impact of MGUC on patient management is not known and should be assessed. To describe MGUC and assess its impact on patient management.Methodology. Microbiology laboratory reports (Leeds, UK) were retrospectively analysed and urine cultures reported as MGUC from a 1 week period underwent detailed laboratory analysis. Semi-structured interviews of NHS clinicians' response to MGUC reports were explored for emergent themes.Results. In 2018, 12.4 % (14,323/115,664) of urine specimens processed to detect bacterial pathogens were reported as MGUC. Among a total of 200 MGUC samples identified within 1 week in 2019, detailed laboratory analysis identified 459 bacterial isolates. Enterococcus species (30.1 %) and Escherichia coli (27.5 %) were the most frequently isolated and the most frequent organism combination (24 %). In total, 65.5 % cultures contained two organisms and 82.5 % of all MGUC contained at least one Enterobacterales. Interviews found clinicians believed MGUC reports represented detection of many commensal bacteria. Clinicians indicated they were more likely to diagnose and treat a UTI when provided with urine culture reports derived from detailed microbial analysis of MGUC, including identity and antibiotic sensitivity of organisms.Conclusions. This study highlights the potential underuse of information derived from microbiological analysis of urine samples. Interpretive commentary on reports together with education for interpretation of enhanced reports should be explored further to improve outcomes in patients with UTI.

Development of a biotensegrity focused therapy for the treatment of pelvic organ prolapse: A retrospective case series.

INTRODUCTION: Pelvic organ prolapse (POP), the bulging of pelvic organs into the vagina, is a common condition thought to be caused by weak pelvic tissue. There is a paucity of evidence supporting current treatment approaches. This case series proposes a new biotensegrity-focused hypothesis that POP is caused by taut pelvic tissue and that releasing pelvic tension will improve POP. METHODS: Three retrospective patient cohorts are presented illustrating the development of the new biotensegrity-focused therapy (BFT) approach. All women received: postural assessment; pelvic tissue examination; and myofascial release of taut pelvic tissue, trigger points, and scar tissue. A standard assessment protocol (SOTAP) recorded patients' Subjective experience, the therapist's Objective assessment, the Treatment plan, Assessment of treatment outcomes, and subsequent treatment and self-care Plans. Cohort three additionally self-reported symptoms using the short-form PDFI-20 questionnaire at baseline and after final treatment. RESULTS: Twenty-three women participated (Cohort 1 n = 7; Cohort 2 n = 7; Cohort 3 n = 9). Fourteen (61%) presented with cystocele, 10 (44%) urethracele, 7 (30%), cervical descent, and 17 (74%) rectocele. Seven (30%) presented with single prolapse, 8 (35%) double, 6 (26%) triple, and 2 (9%) quadruple. Median treatments received was 5 (range 3-8). All women reported improved prolapse symptoms. Cohort 3 (n = 9) reported clinically meaningful reductions (mean 56%) in PFDI-20 total after final treatment. CONCLUSIONS: This case series offers preliminary evidence for the association between POP and pelvic tissue tension. Further research is needed to explore these findings and to determine the efficacy of BFT for treating POP in a wider sample.

Cancer as a chronic illness: support needs and experiences.

OBJECTIVES: Patients are living longer with active, advanced or metastatic disease that cannot be cured, but may be managed (ie, 'chronic cancer'). The experiences and needs within this growing group are likely to be different from those shortly after diagnosis, on active curative treatment, or in the palliative or end-of-life phase, yet are poorly defined. We described chronic cancer patient experiences and support needs in a quantitative, multicentre cross-sectional study. METHODS: Patients from five district general hospitals in England completed the 75-item Chronic Cancer Experiences Questionnaire (CCEQ). Responses were described and linear regression analysis was performed to explore the associations between poorer patient experiences and clinical/sociodemographic variables. RESULTS: In total, 416 patients with prostate cancer (28%), breast cancer (24%), gynaecological cancer (19%), colorectal/gastrointestinal cancer (17%) and renal cancer (12%) completed the CCEQ (response rate 90%). Younger patients, those who had a longer interval between primary and advanced diagnosis and those not in a relationship, had worse experiences (R2=0.098, p<0.05). Cancer-specific symptoms were common, with 80% of participants experiencing fatigue. Areas related to poorest experiences include the coordination of care, general practitioner involvement, coping with limitations, and worries and anxieties. CONCLUSIONS: Psychological burden remains high in the chronic phase of cancer, and patients experience ongoing difficulties in accessing support and services. Younger patients who have been ill for longer and those who have less social support may be particularly vulnerable, and future studies are needed to investigate the best way to meet the unique needs of this growing patient population.

'If you can't see a dilemma in this situation you should probably regard it as a warning': a metasynthesis and theoretical modelling of general practitioners' opioid prescription experiences in primary care.

INTRODUCTION: The prescribing of opioids has increased internationally in developed countries in recent decades within primary and secondary care. The majority of patients with chronic non-malignant pain (CNMP) are managed by their general practitioner (GP). Recent qualitative studies have examined the issue of opioid prescribing for CNMP from a GP viewpoint. The aim of this study is to identify and synthesise the qualitative literature describing the factors influencing the nature and extent of opioid prescribing by GPs for patients with CNMP in primary care. METHODS: MEDLINE, Embase, PsycINFO, Cochrane Database, International Pharmaceutical Abstracts, Database of Abstracts of Reviews of Effects, CINAHL and Web of Science were systematically searched from January 1986 to February 2018. The full text of included articles was reviewed using the Critical Appraisal Skills Programme (CASP) tool for qualitative research. The papers were coded by two researchers and themes organised using Thematic Network Analysis. Themes were constructed in a hierarchical manner, basic themes informed organising themes which informed global themes. A theoretical model was derived using global themes to explain the interplay between factors influencing opioid prescribing decisions. RESULTS: From 7020 records, 21 full text papers were assessed, and 13 studies included in the synthesis; 9 were from the United States, 3 from the United Kingdom and 1 from Canada. Four global themes emerged: suspicion, risk, agreement and encompassing systems level factors. These global themes are inter-related and capture the complex decision-making processes underlying opioid prescribing whereby the physician both consciously and unconsciously quantifies the risk-benefit relationship associated with initiating or continuing an opioid prescription. CONCLUSION: Recognising the inherent complexity of opioid prescribing and the limitations of healthcare systems is crucial to developing opioid stewardship strategies to combat the rise in opioid prescription morbidity and mortality.

Evaluating the experiences and support needs of people living with chronic cancer: development and initial validation of the Chronic Cancer Experiences Questionnaire (CCEQ).

BACKGROUND: Many advanced cancers are managed as chronic diseases, yet there are currently no international guidelines for the support of patients living with chronic cancer. It is important to understand whether care and service arrangements meet the needs of this rapidly growing patient group. This study aimed to develop and validate a questionnaire to capture patients' experiences of living with chronic cancer and their views of clinical and support services. METHODS: The research was carried out between 1 July 2010 and 21 February 2013. A conceptual framework and initial item bank were derived from prior interviews with 56 patients with chronic cancer. Items were reviewed by 4 oncologists and 1 clinical nurse specialist and during 2 focus groups with 9 patients. Pilot questionnaires were completed by 416 patients across 5 cancer units. Item selection and scale reliability was explored using descriptive data, exploratory factor analysis, internal consistency analyses, multitrait scaling analyses and known-groups comparisons. RESULTS: The final Chronic Cancer Experiences Questionnaire (CCEQ) includes 75 items. 62 items contribute to 14 subscales with internal consistency between α 0·68-0·88 and minimal scaling errors. Known-groups comparisons confirmed subscale utility in distinguishing between patient groups. Subscales were labelled: managing appointments, coordination of care, general practitioner involvement, clinical trials, information and questions, making treatment decisions, symptom non-reporting, key worker, limitations, sustaining normality, financial advice, worries and anxieties, sharing feelings with others, and accessing support. 13 items assessing symptom experiences were retained as single items. CONCLUSIONS: The CCEQ has the potential to be used as a clinical instrument to assess patient experiences of chronic cancer or to screen for patient needs. It may also be used as an outcome measure for evaluating programmes and models of care and may identify areas for service development that could ultimately improve the care and support received by patients with chronic cancer.

Systematic review and meta-analysis of pre-hospital diagnostic accuracy studies.

INTRODUCTION: Paramedics are involved in examining, treating and diagnosing patients. The accuracy of these diagnoses is evaluated using diagnostic accuracy studies. We undertook a systematic review of published literature to provide an overview of how accurately paramedics diagnose patients compared with hospital doctors. A bivariate meta-analysis was incorporated to examine the range of diagnostic sensitivity and specificity. METHODS: We searched MEDLINE, CINAHL, Embase, AMED and the Cochrane Database from 1946 to 7 May 2016 for studies where patients had been given a diagnosis by paramedics and hospital doctors. Keywords focused on study type ('diagnostic accuracy'), outcomes (sensitivity, specificity, likelihood ratio?, predictive value?) and setting (paramedic*, pre-hospital, ambulance, 'emergency service?', 'emergency medical service?', 'emergency technician?'). RESULTS: 2941 references were screened by title and/or abstract. Eleven studies encompassing 384 985 patients were included after full-text review. The types of diagnoses in one of the studies encompassed all possible diagnoses and in the other studies focused on sepsis, stroke and myocardial infarction. Sensitivity estimates ranged from 32% to 100% and specificity estimates from 14% to 100%. Eight of the studies were deemed to have a low risk of bias and were incorporated into a meta-analysis which showed a pooled sensitivity of 0.74 (0.62 to 0.82) and a pooled specificity of 0.94 (0.87 to 0.97). DISCUSSION: Current published research suggests that diagnoses made by paramedics have high sensitivity and even higher specificity. However, the paucity and varying quality of studies indicates that further prehospital diagnostic accuracy studies are warranted especially in the field of non-life-threatening conditions.

Asking the right questions to get the right answers: using cognitive interviews to review the acceptability, comprehension and clinical meaningfulness of patient self-report adverse event items in oncology patients.

BACKGROUND: Standardized reporting of treatment-related adverse events (AE) is essential in clinical trials, usually achieved by using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) reported by clinicians. Patient-reported adverse events (PRAE) may add value to clinician assessments, providing patient perspective on subjective toxicity. We developed an online patient symptom report and self-management system for real-time reporting and managing AE during cancer treatment integrated with electronic patient records (eRAPID). As part of this program we developed a patient version of the CTCAE (version 4.0), rephrasing terminology into a self-report format. We explored patient understanding of these items via cognitive interviews. MATERIAL AND METHOD: Sixty patients (33 female, 27 male) undergoing treatment were purposively sampled by age, gender and tumor group (median age 61.5, range 35-84, 12 breast, 12 gynecological, 13 colorectal, 12 lung and 11 renal). Twenty-one PRAE items were completed on a touch-screen computer. Subsequent audio-recorded cognitive interviews and thematic analysis explored patients' comprehension of items via verbal probing techniques during three interview rounds (n = 20 patients/round). RESULTS: In total 33 item amendments were made; 29% related to question comprehension, 68% response option and 3% order effects. These amendments to phrasing and language improved patient understanding but maintained CTCAE grading and key medical information. Changes were endorsed by members of a patient advisory group (N = 11). CONCLUSION: Item adaptations resulted in a bank of consistently interpreted self-report AE items for use in future research program. In-depth analysis of items through cognitive interviews is an important step towards developing an internationally valid system for PRAE, thus improving patient safety and experiences during cancer treatment.

The role of the intermediate care team in detecting and responding to loneliness in older clients.

The intermediate care team supports patients in their own homes to manage complex needs. They are ideally placed in the community to identify older adults at risk of loneliness. However, little is known about how intermediate care team professionals perceive, detect or respond to loneliness in their clients. This study explores intermediate care team professionals' attitudes to loneliness in the context of perceived service priorities and their experiences of managing loneliness in their clients. Eight professionals (n=2 physiotherapists, n=3 occupational therapists, n=3 nurses) took part in semi-structured interviews. Data were analysed thematically using framework analysis, applying the theory of planned behaviour as an interpretive framework. Intermediate care team professionals see loneliness as a significant issue for many of their older clients but a low priority for intermediate care team services. They believe that loneliness often goes undetected because it is difficult to measure objectively. Barriers to managing loneliness included high workloads, unsatisfactory referral systems and lack of close working with social care and independent sector services. Brief but reliable loneliness assessments into routine practice, receiving training on detecting and managing loneliness, and improving working relationships with social care and independent sector services were highlighted as strategies that could improve the detection and management of loneliness in intermediate care team clients.

Defining chronic cancer: patient experiences and self-management needs.

OBJECTIVE: Chronic cancer is poorly defined and strategies for supporting patients during this disease phase are lacking. This research defines chronic cancer, explores patient experiences and reviews patients' support needs against those described in the 2007 Department of Health Generic Choice Model for Long-term Conditions (DoH-GCM). DESIGN: Semistructured interviews were audio recorded, transcribed and data explored for emergent themes. The a priori themes from DoH-GCM were applied: clinical support; self-care and self-management; supporting independence; psychological support; and social and economic factors. RESULTS: 56 patients >12 months postdiagnosis of advanced cancer were recruited from five clinics at a Yorkshire cancer centre: breast (n=11); renal (n=11); colorectal/gastrointestinal (n=12); gynaecological (n=12); and prostate (n=10). Most patients aspired to living normal lives. Challenges included frequent and lengthy hospital appointments, long-term symptom control and uncertainty. Only renal and prostate patients reported routine access to specialist nursing. Uptake of support services was varied and there was generally poor understanding of support pathways for non-medical problems and issues occurring when patients were not receiving active treatment. There was variation in coping strategies and ability of patients to attain a positive outlook on life. CONCLUSIONS: For patients to do well in this cancer phase requires good self-management of symptoms plus taking an active role in accessing appropriate services as needed. Care planning at the point of transition to the chronic phase of cancer should focus on evaluating patients' needs, clarifying support pathways, increasing the profile and involvement of community services and organisations, and supporting patients and families develop effective self-management skills.

Levels of state and trait anxiety in patients referred to ophthalmology by primary care clinicians: a cross sectional study.

PURPOSE: There is a high level of over-referral from primary eye care leading to significant numbers of people without ocular pathology (false positives) being referred to secondary eye care. The present study used a psychometric instrument to determine whether there is a psychological burden on patients due to referral to secondary eye care, and used Rasch analysis to convert the data from an ordinal to an interval scale. DESIGN: Cross sectional study. PARTICIPANTS AND CONTROLS: 322 participants and 80 control participants. METHODS: State (i.e. current) and trait (i.e. propensity to) anxiety were measured in a group of patients referred to a hospital eye department in the UK and in a control group who have had a sight test but were not referred. Response category analysis plus infit and outfit Rasch statistics and person separation indices were used to determine the usefulness of individual items and the response categories. Principal components analysis was used to determine dimensionality. MAIN OUTCOME MEASURE: Levels of state and trait anxiety measured using the State-Trait Anxiety Inventory. RESULTS: State anxiety scores were significantly higher in the patients referred to secondary eye care than the controls (p<0.04), but similar for trait anxiety (p>0.1). Rasch analysis highlighted that the questionnaire results needed to be split into "anxiety-absent" and "anxiety-present" items for both state and trait anxiety, but both subscales showed the same profile of results between patients and controls. CONCLUSIONS: State anxiety was shown to be higher in patients referred to secondary eye care than the controls, and at similar levels to people with moderate to high perceived susceptibility to breast cancer. This suggests that referral from primary to secondary eye care can result in a significant psychological burden on some patients.

A mixed methods approach to adapting health-related quality of life measures for use in routine oncology clinical practice.

PURPOSE: The current study reviewed and adapted existing health-related quality of life (HRQoL) instruments for use in routine clinical practice delivering outpatient chemotherapy for colorectal, breast and gynaecological cancers. METHODS: 564 (288 gynaecological, 208 breast and 68 colorectal) outpatient consultations of 141 patients were audio-recorded and analysed to identify discussed issues. Issues were ranked from most to least commonly discussed within each disease group. Existing HRQoL instruments were evaluated against these lists and best fitting items entered into cancer-specific item banks. Item banks were evaluated during semi-structured interviews by twenty-one oncologists (13 consultants and 8 specialist registrars), four clinical nurse specialists and thirty patients, from breast, gynaecological and colorectal cancer practices. Pilot questionnaires were completed by 448 (145 breast, 148 gynaecological and 155 colorectal) patients attending outpatient clinics. Item selection and scale reliability was explored using descriptive data and psychometric methods alongside qualitative patient and clinician ratings. RESULTS: Each questionnaire includes five physical and three psychosocial function scales each with good internal consistency reliability (α > 0.70) plus disease-specific individual-symptom items identified as useful in clinical practice. CONCLUSIONS: Three cancer-specific health-related quality of life measures were developed for use in routine clinical practice. Initial analyses suggest good clinical utility and acceptable psychometric properties for the new instruments.

Interventions for sexual problems following treatment for breast cancer: a systematic review.

Sexual functioning is an important element of quality of life. Many women experience sexual problems as a result of a breast cancer diagnosis and its treatment. Little is known about the availability and the effectiveness of interventions for sexual problems in this patient population. Six electronic databases were searched using Medical Subject Headings and keywords. Additional hand searching of the references of relevant papers was also conducted. The searches were conducted between October 2010 and January 2011. Papers were included if they evaluated interventions for sexual problems caused as a result of breast cancer or its treatment. Studies were only included if sexual functioning was reported using a patient-reported outcome questionnaire. Studies were excluded if sexual functioning was measured but improving sexual problems was not one of the main aims of the intervention. 3514 papers were identified in the initial search. 21 papers were selected for inclusion. Studies were of mixed methodological quality; 15 randomised trials were identified, many included small sample sizes and the use of non-validated questionnaires. Three main types of interventions were identified: Exercise (2), medical (2) and psycho-educational (17). The psycho-educational interventions included skills-based training such as problem-solving and communication skills, counselling, hypnosis, education and specific sex-therapies. Interventions were delivered to individual patients, patients and their partners (couple-based) and groups of patients. The widespread methodological variability hinders the development of a coherent picture about which interventions work for whom. Tentative findings suggest the most effective interventions are couple-based psycho-educational interventions that include an element of sexual therapy. More methodologically strong research is needed before any intervention can be recommended for clinical practice. Improved screening and classification of sexual problems will ensure interventions can be more effectively targeted to suit individual patient needs.

Discussion of emotional and social impact of cancer during outpatient oncology consultations.

OBJECTIVE: Following publication of national guidelines on detection and management of psychosocial problems in oncology, this study explores frequency of discussion of emotional and social issues in outpatient oncology consultations. METHODS: Analysis of baseline data from 212 outpatients participating in a randomized controlled trial. Baseline data included content analysis of audio recordings of consultations, Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire subscale scores, and patient and clinician self-rated preferences and perceptions of communication. RESULTS: Fifty-nine percent patients and 75% clinicians expressed preferences to discuss emotional issues during consultations. Analysis of audio recordings showed that they were discussed in 27% of the consultations, regardless of severity of emotional problems reported by patients (FACT-G Emotional well-being subscale). Fifty percent of clinicians reported discussing emotional issues 'often' or 'almost always', compared with 18% of patients. Forty-four percent patients and 39% clinicians reported that they would discuss social activities, but they were actually discussed in 46% of consultations. Patients predominantly initiated discussion of emotional and social issues (85 and 60% consultations, respectively). CONCLUSIONS: Low prevalence of discussion of psychosocial issues cannot be accounted for by patient or clinician communication preferences. If clinicians rely on patients to initiate discussion of psychosocial issues, patients' problems may go unaddressed.

Patients report improvements in continuity of care when quality of life assessments are used routinely in oncology practice: secondary outcomes of a randomised controlled trial.

INTRODUCTION AND AIM: In a randomised trial investigating the effects of regular use of health-related quality of life (HRQOL) in oncology practice, we previously reported an improvement in communication (objective analysis of recorded encounters) and patient well-being. The secondary aims of the trial were to measure any impact on patient satisfaction and patients' perspectives on continuity and coordination of their care. METHODS: In a prospective trial involving 28 oncologists, 286 cancer patients were randomised to: (1) intervention arm: regular touch-screen completion of HRQOL with feedback to physicians; (2) attention-control arm: completion of HRQOL without feedback; and (3) control arm: no HRQOL assessment. Secondary outcomes were patients' experience of continuity of care (Medical Care Questionnaire, MCQ) including 'Communication', 'Coordination' and 'Preferences to see usual doctor' subscales, patients' satisfaction, and patients' and physicians' evaluation of the intervention. Analysis employed mixed-effects modelling, multiple regression and descriptive statistics. RESULTS: Patients in the intervention arm rated their continuity of care as better than the control group for 'Communication' subscale (p=0.03). No significant effects were found for 'Coordination' or 'Preferences to see usual doctor'. Patients' evaluation of the intervention was positive. More patients in the intervention group rated the HRQOL assessment as useful compared to the attention-control group (86% versus 29%), and reported their doctors considered daily activities, emotions and quality of life. CONCLUSION: Regular use of HRQOL measures in oncology practice brought changes to doctor-patient communication of sufficient magnitude and importance to be reported by patients. HRQOL data may improve care through facilitating rapport and building inter-personal relationships.

Patient experiences of continuity of cancer care: development of a new medical care questionnaire (MCQ) for oncology outpatients.

OBJECTIVES: To adapt the Components of Primary Care Index (CPCI) to be applicable to oncology outpatients and to assess the reliability and validity of the adapted instrument (renamed the Medical Care Questionnaire [MCQ]). METHODS: The development and validation of the MCQ took place in four phases. Phase 1 reviewed the literature and examined existing measures. In Phase 2, the selected instrument (CPCI) was reviewed by a panel of experts using a stepwise consensus procedure. In Phase 3, the adapted 21-item MCQ was administered to 200 outpatients attending oncology appointments. The instrument was refined to 15 items and in Phase 4, it was completed by 477 oncology outpatients. The psychometric properties of the new instrument were assessed using exploratory factor analysis (EFA), confirmatory factor analysis, multitrait scaling analysis, and by comparing MCQ scores between known groups. RESULTS: EFA of the 15-item MCQ suggested three subscales with acceptable to good reliability: "Communication"alpha = 0.69; "Coordination"alpha = 0.84; and "Preferences"alpha = 0.75. Comparing known groups showed that patients who saw fewer doctors during their clinic visits reported stronger "Preferences" to see their usual doctor and rated "Communication" with their doctors as better than patients who saw more doctors during their clinic visits. CONCLUSION: The MCQ demonstrates good psychometric properties in the target population. It is a brief and simple-to-use instrument, which provides a valid perspective on patients' experiences of communicating with doctors and their perceptions of the continuity and coordination of their cancer care.

Stepping over obstacles: attention demands and aging.

Older adults have been shown to trip on obstacles despite taking precautions to step carefully. It has been demonstrated in dual-task walking that age-related decline in cognitive and attentional mechanisms can compromise postural management. This is yet to be substantiated during obstacle negotiation when walking. Forty-six healthy volunteers (aged 20-79 years) stepped over obstacles in their path whilst walking and performing a verbal fluency task. Using 3D kinematic analysis we compared obstacle crossing during single-task (obstacle crossing only) and dual-task (obstacle crossing with verbal task) conditions. We grouped the participants into three age groups and examined age-related changes to cognitive interference on obstacle crossing. During dual-task trials, the 20-29 and 60-69 groups stepped closer to the obstacles prior to crossing, increased vertical toe-obstacle clearance, and had reduced gait variability. In these two groups there was a small dual-task decrease in verbal output. The 70-79 group applied similar dual-task stepping strategies during pre-crossing. However, during crossing they showed reduced vertical toe-to-obstacle clearance and increased variability of obstacle-to-heel distance. Additionally, this group did not show any significant change to verbal output across trials. These results suggest that with advanced age, increased cognitive demands are more likely to have a detrimental impact on motor performance, leading to compromised safety margins and increased variability in foot placement. We conclude that younger adults utilise a posture-preserving strategy during complex tasks but the likelihood of this strategy being used decreases with advanced age.
