AbstractBackground and purposePain is a common symptom associated with multiple sclerosis (MS), and has lasting effects on an individual’s functional capacity and quality of life. A wide range of prevalence rates of pain (between 23% and 90%)have been reported in MS and this is mainly due to the methodological differences amongst the studies such as variability in patient sources, method of sampling and the definition of pain used. Chronic pain in MS, defined as pain lasting for greater than 3–6 months, can have a significant impact on their biopsychosocial health, including negative impact on activities of daily living, relationships and social participation. The long-term course of MS-related pain and its impact in an Australian cohort over a 7-year period has been investigated earlier. The aim of this longitudinal study was to describe the impact of chronic pain, pain-related disability and carer burden in persons with MS over a 10-year period. The aim of this longitudinal study was to describe the impact of chronic pain, pain-related disability and carer burden in persons with MS over a 10-year period.MethodsThis was a prospective longitudinal study conducted at the Rehabilitation Department of Royal Melbourne Hospital (RMH), a tertiary referral hospital in Victoria and Australia. The source of participants was from the RMH MS database and contains detailed MS patient information including demographic data, diagnosis details (using McDonald’s criteria), pain characteristics. Structured face-face interviews and validated measures were used, which include the visual analogue scale (VAS); chronic pain grade (CPG); the assessment of quality of life (AQoL) and the carer strain index (CSI). The mean age of the participants (n = 70) was 55.3 years and majority (70%) were female.ResultsThe mean age of the participants (n = 70) was 55.3 years and majority (70%) were female. The findings show that over time (10 years), participants report having greater bilateral bodily pain and greater description of pain as ‘worse as it could be’. Pain types were similar to 7-years follow-up but remained higher than baseline. There was a significant deterioration in quality of life in those with more severe CPG over time. Almost half of the participants 31 (44%) required care either from a private carer, institution or from a family member. Although fear of taking medications and side effects were common barriers to treatment for pain, there was an increase in the use of pharmacological treatment over time and an increase in the use of healthcare services, mainly neurologists and general practitioners.ConclusionsThe pain measures reported by the participants were similar to those at the 7-year follow-up except there was a greater representation of bilateral pain locations (limb, trunk and facial pain) compared to baseline and 7-year follow-up. At 10-year follow-up, more participants used medications compared tc 7-year follow-up and there was an increase in the use of health professionals at the 10-year follow-up At the 10-year follow up QoL of the participants deteriorated significantly and more participants had progressed to higher CPGIII and CPGIV. This study demonstrates that chronic pain is a significant issue over time in MS, with clinical and health implications, impact on quality of life, disability and healthcare utilization.ImplicationsGreater awareness of chronic pain in pwMS, cognitive classifications and an interdisciplinary approach is required to improve long-term patient outcomes and well-being.Crown Copyright © 2017 Published by Elsevier B.V. on behalf of Scandinavian Association for the Study of Pain.

Abstract BACKGROUND PCV+RT substantially prolongs survival in AO patients, but long-term CF and QOL implications are unclear. We compared CF and QOL by treatment arm in RTOG 9402 participants and evaluated the impact that baseline characteristics had on CF, QOL, and survival. METHODS CF and QOL were evaluated using the Mini Mental State Exam (MMSE) and Brain-Quality of Life (B-QOL) scale at baseline and annually. Scores were analyzed between treatment arms at each time point for patients with ≥ 10 years of follow-up data. Shared parameter models evaluated MMSE and B-QOL scores and survival for all patients. RESULTS 42/148 (28.4%) participants in PCV+RT and 20/143 (14%) in RT alone arms survived ≥ 10 years. 35/42 and 39/42 (PCV+RT) and 18/20 and 17/20 (RT) participants completed baseline B-QOL and MMSE assessments, respectively. B-QOL scores did not differ between treatment groups at any time-point. Among 16 patients (10 PCV+RT, 6 RT) who completed year 10 MMSE evaluations, mean MMSE score at 10 years was higher in the RT arm (29.83 [95% CI 22.1, 30.0] vs. 26.50 [95% CI 29.4, 30.0], P= 0.04). Change in MMSE and B-QOL scores from baseline did not differ significantly between treatment groups at any time. In shared parameter models including all patients with baseline assessments, MMSE and B-QOL scores decreased over time (MMSE P= 0.0189, B-QOL P= 0.0005), but this did not differ by treatment group (MMSE P= 0.5727, B-QOL P= 0.3592). Younger age and higher KPS predicted better scores (MMSE P < 0.0001, P = 0.0002; B-QOL P = 0.0043, P = 0.0007). PCV+RT predicted better survival in both models. CONCLUSIONS PCV+RT improves survival in AO. Shared parameter models show decrease in MMSE and B-QOL over time. However, relative to RT alone, the addition of PCV did not impact change in CF and QOL over time.

Long-term health consequences in survivors of severe COVID-19 remain unclear. Eighteen COVID-19 patients admitted to the intensive care unit at the University Hospital Rechts der Isar, Munich, Germany, between 14 March and 23 June 2020, were prospectively followed-up at a median of 36, 75.5, 122 and 222 days after discharge. The health-related quality of life (HrQoL) (36-item Short Form Health Survey and St. George’s Respiratory Questionnaire, SGRQ), cardiopulmonary function, laboratory parameters and chest imaging were assessed longitudinally. The HrQoL assessment revealed a reduced physical functioning, as well as increased SGRQ impact and symptoms scores that all improved over time but remained markedly impaired compared to the reference groups. The median radiological severity scores significantly declined; persistent abnormalities were found in 33.3% of the patients on follow-up. A reduced diffusion capacity was the most common abnormal pulmonary function parameter. The length of hospitalization correlated with role limitations due to physical problems, the SGRQ symptom and the impact score. In conclusion, in survivors of severe COVID-19, the pulmonary function and symptoms improve over time, but impairments in their physical function and diffusion capacity can persist over months. Longer follow-up studies with larger cohorts will be necessary to comprehensively characterize long-term sequelae upon severe COVID-19 and to identify patients at risk.

Abstract Background/Aims  Axial spondyloarthritis (axSpA) is a chronic rheumatic condition, characterised by inflammatory back pain - often associated with impaired function and mobility, sleep disturbance, fatigue, and reduced quality of life. Despite the vast advances in pharmacological treatments for axSpA over the last few decades, physical activity and rehabilitation remain vital for effective disease management. At the Royal National Hospital for Rheumatic Diseases in Bath (RNHRD), the 2-week inpatient axSpA rehabilitation programme has been integral to axSpA care since the 1970’s. Prior research has demonstrated significant short-term improvements in spinal mobility (BASMI), function (BASFI) and disease activity (BASDAI) following course attendance. However, the long-term outcomes are yet to be evaluated in this unique cohort. Methods  Since the early 1990’s, clinical measures of spinal mobility, function and disease activity have been routinely collected at the RNHRD at all clinical appointments through administration of the BASMI, BASFI and BASDAI, respectively. Dates of attending the axSpA course and standard clinical and treatment follow-up data were also collected. Multiple linear regression models were used to investigate the impact of course attendance on final reported BASMI, BASDAI and BASFI scores (final score=most recent). Length of follow-up was defined as time between first and last recorded BASMI. Results  Of the 203 patients within the Bath SPARC200 cohort, 77.8% (158/203) had attended at least one rehabilitation course throughout follow-up. 70.0% (140/203) of patients were male. The mean duration of follow-up was 13.5 years (range 0-35 years); 28.1% (57/203) of individuals with 20+ years of follow-up. Course attendance (yes versus no) significantly reduced final BASMI score by 0.84 (p = 0.001, 95%CI -1.31 to -0.37) and final BASDAI score by 0.74 (p = 0.018, 95%CI -1.34 to -0.13). Although course attendance reduced final BASFI by 0.45 (95%CI -1.17 to 0.28), this relationship did not reach significance (p = 0.225). Whilst minimally clinically important difference (MCID) is, to our knowledge, yet to be defined for BASMI, MCIDs were achieved long-term for both BASDAI and BASFI - defined by van der Heijde and colleagues in 2016 as 0.7 and 0.4 for BASDAI and BASFI, respectively. Conclusion  These results provide novel evidence to support the integral role of education, physical activity and rehabilitation in the management of axSpA. Future work should investigate additional outcomes of critical importance to patients and clinicians, such as fatigue, quality of life and work productivity. Furthermore, a greater understanding of the factors that confound these outcomes may provide insights into those patients who may most benefit from attending a 2-week rehabilitation course. In addition to facilitating identification of those patients who may require additional clinical support. Disclosure  R. Barnett: None. A. McGrogan: None. M. Young: None. C. Cavill: None. M.

© The Author(s) 2019. Community grandparenting may promote the well-being of older adults. We examined the impact of non-kin and grandparental childcare on quality of life and loneliness using longitudinal data from 2653 older New Zealanders collected over 2 years. Providing both non-kin and grandparental childcare predicted greater self-realisation for women only and was associated with reduced levels of control and autonomy for men. Non-kin childcare was also associated with reduced social loneliness over time independent of gender. Findings suggest that non-kin grandparenting has psychosocial benefits for older adults. Surrogate grandparenting offers promising avenues for those without grandchildren to experience the benefits of grandparenting.

Abstract Background Forced migrants can be exposed to various stressors that can impact their health and wellbeing. How the different stages in the migration process impacts health is however poorly explored. The aim of this study was to examine changes in self-rated health (SRH) and quality of life (QoL) among a cohort of adult Syrian refugees before and after resettlement in Norway. Method We used a prospective longitudinal study design with two assessment points to examine changes in health among adult Syrian resettlement refugees in Lebanon accepted for resettlement in Norway. We gathered baseline data in 2017/2018 in Lebanon and subsequently at follow-up one year after arrival. The main outcomes were good SRH measured by a single validated item and QoL measured by WHOQOL-BREF. We used generalized estimating equations to investigate changes in outcomes over time and incorporated interaction terms in the models to evaluate effect modifications. Results In total, 353 subjects participated in the study. The percentage of participants reporting good SRH showed a non-significant increase from 58 to 63% RR, 95%CI: 1.1 (1.0, 1.2) from baseline to follow-up while mean values of all four QoL domains increased significantly from baseline to follow-up; the physical domain from 13.7 to 15.7 B, 95%CI: 1.9 (1.6, 2.3), the psychological domain from 12.8 to 14.5 B, 95%CI: 1.7 (1.3, 2.0), social relationships from 13.7 to 15.3 B, 95%CI: 1.6 (1.2, 2.0) and the environmental domain from 9.0 to 14.0 5.1 B, 95%CI: (4.7, 5.4). Positive effect modifiers for improvement in SRH and QoL over time include male gender, younger age, low level of social support and illegal status in transit country. Conclusion Our results show that good SRH remain stable while all four QoL domains improve, most pronounced in the environment domain. Understanding the dynamics of migration and health is a fundamental step in reaching health equity.

Object The management strategies and outcomes in pediatric patients with elevated intracranial pressure (ICP) following severe traumatic brain injury (TBI) are examined in this study. Methods This study was a retrospective review of a prospectively acquired pediatric trauma database. More than 750 pediatric patients with brain injury were seen over a 10-year period. Records were retrospectively reviewed to determine interventions for correcting ICP, and surviving patients were contacted prospectively to determine functional status and quality of life. Only patients with 2 years of follow-up were included in the study. Results Ninety-six pediatric patients (age range 3–18 years) were identified with a Glasgow Coma Scale score < 8 and elevated ICP > 20 mm Hg on presentation. The mean injury severity score was 65 (range 30–100). All patients were treated using a standardized head injury protocol. The mean time course until peak ICP was 69 hours postinjury (range 2–196 hours). Intracranial pressure control was achieved in 82 patients (85%). Methods employed to achieve ICP control included maximal medical therapy (sedation, hyperosmolar therapy, and paralysis) in 34 patients (35%), ventriculostomy in 23 patients (24%), and surgery in 39 patients (41%). Fourteen patients (15%) had refractory ICP despite all interventions, and all of these patients died. Seventy-two patients (75%) were discharged from the hospital, whereas 24 (25%) died during hospitalization. Univariate and multivariate analysis revealed that the presence of vascular injury, refractory ICP, and cisternal effacement at presentation had the highest correlation with subsequent death (p < 0.05). Mean follow-up was 53 months (range 11–126 months). Three patients died during the follow-up period (2 due to infections and 1 committed suicide). The mean 2-year Glasgow Outcome Scale score was 4 (median 4, range 1–5). The mean patient competency rating at follow-up was 4.13 out of 5 (median 4.5, range 1–4.8). Univariate analysis revealed that the extent of intracranial and systemic injuries had the highest correlation with long-term quality of life (p < 0.05). Conclusions Controlling elevated ICP is an important factor in patient survival following severe pediatric TBI. The modality used for ICP control appears to be less important. Long-term follow-up is essential to determine neurocognitive sequelae associated with TBI.

Purpose Little is known about change in quality of life (QOL) among long-term cancer survivors. We examined change over time in QOL among long-term survivors of non-Hodgkin lymphoma and identified demographic, clinical, and psychosocial risk factors for poor outcomes. Methods Surveys were mailed to 682 lymphoma survivors who participated in a study 5 years earlier, when on average they were 10.4 years postdiagnosis. Standardized measures of QOL, perceptions of the impact of cancer, symptoms, medical history, and demographic variables were reported at both time points and examined using linear regression modeling to identify predictors of QOL over time. Results A total of 566 individuals participated (83% response rate) who were a mean of 15.3 years postdiagnosis; 52% were women, and 87% were white. One third of participants (32%) reported persistently high or improved QOL, yet a notable proportion (42%) reported persistently low or worsening QOL since the earlier survey. Participants who received only biologic systemic therapy reported improvement in physical health despite the passage of time. Older age, more comorbidity, and more or increasing negative and decreasing positive perceptions of cancer's impact were independent predictors of poor QOL. Lymphoma symptom burden, less social support, and having received a transplantation were related to negative perceptions of cancer's impact. Conclusion Moderate to severe symptom burden, limited social support, or having received a transplantation should alert the clinician to potential need for supportive services. Perceptions of cancer's impact are associated with QOL cross-sectionally and longitudinally; modifying these perceptions may thus provide a strategy for improving QOL.

Structured Abstract Objectives: The long-term consequences of severe Covid-19 requiring hospital admission are not well characterised. The objective of this study was to establish the long-term effects of Covid-19 following hospitalisation and the impact these may have on patient reported outcome measures. Design: A multicentre, prospective cohort study with at least 3 months follow-up of participants admitted to hospital between 5th February 2020 and 5th October 2020. Setting: 31 hospitals in the United Kingdom. Participants: 327 hospitalised participants discharged alive from hospital with confirmed/high likelihood SARS-CoV-2 infection. Main outcome measures and comparisons: The primary outcome was self-reported recovery at least ninety days after initial Covid-19 symptom onset. Secondary outcomes included new symptoms, new or increased disability (Washington group short scale), breathlessness (MRC Dyspnoea scale) and quality of life (EQ5D-5L). We compared these outcome measures across age, comorbidity status and in-hospital Covid-19 severity to identify groups at highest risk of developing long-term difficulties. Multilevel logistic and linear regression models were built to adjust for the effects of patient and centre level risk factors on these outcomes. Results: In total 53.7% (443/824) contacted participants responded, yielding 73.8% (327/443) responses with follow-up of 90 days or more from symptom onset. The median time between symptom onset of initial illness and completing the participant questionnaire was 222 days (Interquartile range (IQR) 189 to 269 days). In total, 54.7% (179/327) of participants reported they did not feel fully recovered. Persistent symptoms were reported by 93.3% (305/325) of participants, with fatigue the most common (82.8%, 255/308), followed by breathlessness (53.5%, 175/327). 46.8% (153/327) reported an increase in MRC dyspnoea scale of at least one grade. New or worse disability was reported by 24.2% (79/327) of participants. Overall (EQ5D-5L) summary index was significantly worse at the time of follow-up (median difference 0.1 points on a scale of 0 to 1, IQR: -0.2 to 0.0). Females under the age of 50 years were five times less likely to report feeling recovered (adjusted OR 5.09, 95% CI 1.64 to 15.74), were more likely to have greater disability (adjusted OR 4.22, 95% CI 1.12 to 15.94), twice as likely to report worse fatigue (adjusted OR 2.06, 95% CI 0.81 to 3.31) and seven times more likely to become more breathless (adjusted OR 7.15, 95% CI 2.24 to 22.83) than men of the same age. Conclusions: Survivors of Covid-19 experienced long-term symptoms, new disability, increased breathlessness, and reduced quality of life. These findings were present even in young, previously healthy working age adults, and were most common in younger females. Policymakers should fund further research to identify effective treatments for long-Covid and ensure healthcare, social care and welfare support is available for individuals with long-Covid.

Background: The Atrial Fibrillation Effect on QualiTy-of-Life (AFEQT) survey has recently been validated to measure the impact of atrial fibrillation on patients’ quality of life, but a clinically important difference (CID) in AFEQT score has not been defined. Knowing the CID is needed to interpret the meaningfulness of differences between treatments in clinical trials; or patient populations for quality assessment. Objectives: To calculate CID values in AFEQT in the ORBIT registry. Methods: ORBIT-AF is a US-based outpatient AF registry that measured disease-specific QoL with the AFEQT tool (score range= 0 (worst) to 100) at baseline and at 1 year follow-up. Two anchor-based methods were used to relate changes in AFEQT to clinically important differences in the more established European Heart Rhythm Association (EHRA) measure of functional status. Ranging from 1 (no symptoms) to 4 (disabling), a change of 1 EHRA class was defined as an important change in the anchor. Both the mean change and receiver operating characteristics (ROC) methods were then used to identify CIDs in AFEQT at 1 year follow-up. This was done for both improvement and worsening on the anchor. The mean change method defines a CID as the mean change in AFEQT score among patients with a 1 EHRA class change. The ROC method identifies a CID as the point on the ROC curve that best discriminates patients who experienced an important change in the anchor (≥ 1 EHRA class change) from those who experienced no change. Results: AFEQT was assessed in 2008 AF patients at baseline and 1347 patients at 1 year from 99 US sites participating in ORBIT-AF. CIDs and 95% confidence intervals (CI) corresponding to an improvement in EHRA for the mean change method were 5.4 (3.6, 7.2) AFEQT points and 1.9 (0.4, 9.3) AFEQT points for the ROC method. CIDs corresponding to worsening in EHRA for the mean change method were -4.2 (-6.9,-1.5) AFEQT points and -7.4 (-13.9,-4.6) AFEQT points for the ROC method. Conclusions: Changes in AFEQT as small as 2 points may be clinically relevant, although CIDs vary depending on the method of calculation. The variability suggests identifying a single universal CID to assess improvement in quality of life in AF patients may not be ideal and improvement may relate to the nature of a patient’s symptoms and their baseline level of activity.
