Activity pacing is associated with better and worse symptoms for patients with long-term conditions

Background: Activity pacing has been associated with both improved and worsened symptoms, and its role in reducing disability among patients with long-term conditions has been questioned. However, existing studies have measured pacing according to unidimensional subscales, and therefore the empirical evidence for pacing as a multifaceted construct remains unclear. We have developed a 26-item Activity Pacing Questionnaire (APQ-26) for chronic pain/fatigue containing 5 themes of pacing: activity adjustment, activity consistency, activity progression, activity planning, and activity acceptance. Objective: To assess the associations between the 5 APQ-26 pacing themes and symptoms of pain, physical fatigue, depression, avoidance, and physical function. Methods: Cross-sectional questionnaire study design. Data analyzed using multiple regression. Participants: A total of 257 adult patients with diagnoses of chronic low back pain, chronic widespread pain, fibromyalgia, and chronic fatigue syndrome/myalgic encephalomyelitis. Results: Hierarchical multiple regression showed that activity adjustment was significantly associated with increased physical fatigue, depression, and avoidance, but decreased physical function (all Ps≤0.030). Activity consistency was associated with decreased pain, physical fatigue, depression, and avoidance, but increased physical function (all Ps≤0.003). Activity planning was associated with reduced physical fatigue (Ps=0.025) and activity acceptance was associated with increased avoidance (Ps=0.036). Conclusions: Some APQ-26 pacing themes were associated with worse symptoms and others with symptom improvement. Specifically, pacing themes involving adjusting/reducing activities were associated with worse symptoms, whereas pacing themes involving undertaking consistent activities were associated with improved symptoms. Future study will explore the causality of these associations to add clarification regarding the effects of pacing on patients’ symptoms

Exploring patients’ opinions of activity pacing and a new activity pacing questionnaire for chronic pain and/or fatigue:a qualitative study

Objective: Despite the frequent recommendation of activity pacing as a coping strategy for patients with chronic pain and/or fatigue, pacing is interpreted in different ways and there is an absence of a widely accepted pacing scale. We have developed a new Activity Pacing Questionnaire(APQ). The aims of this study were to explore patients’ views and beliefs about the concept of pacing, together with the acceptability of the APQ. Design: Qualitative pragmatic study using semi-structured telephone interviews. Data were analysed using Framework analysis. Participants 16 adult patients attending secondary care physiotherapy out-patient departments were recruited via purposive sampling. Diagnoses included chronic low back pain, chronic widespread pain, fibromyalgia and chronic fatigue syndrome/myalgic encephalomyelitis. Findings: Pacing emerged as a multifaceted concept from participants’ descriptions. The implementation of pacing was influenced by participants’ age, the presence of co-morbidities and participants’ emotions. The APQ was found to be generally acceptable in comparison to two existing pacing subscales. Participants undertook activities using quota/symptom-contingent approaches. Four behavioural typologies emerged: Task avoidance, Task persistence, Task fluctuation (boom-bust) and Task modification (activity pacing). Conclusions: The APQ appears to be easy to complete, and acceptable to patients who are attending physiotherapy for the management of long-term conditions. It emerged that individual patients implemented different pacing facets to varying degrees, and that different behavioural typologies were apparent. The relationships between behavioural typologies and facets of pacing warrant further investigation to facilitate the development of effective tailored pacing interventions

Psychosocial predictors of health-related quality of life and health service utilisation in people with chronic low back pain

Psychological and social factors have been shown, separately, to predict outcome in individuals with chronic low back pain. Few previous studies, however, have integrated both psychological and social factors, using prospective study of clinic populations of low back pain patients, to identify which are the most important targets for treatment. One hundred and eight patients with chronic low back pain, newly referred to an orthopaedic outpatient clinic, completed assessments of demographic characteristics, details of back pain, measures of anxiety and depression (Hospital Anxiety and Depression Scale, HADS), fearful beliefs about pain (Fear Avoidance Beliefs Questionnaire), social stresses (Life Events and Difficulties Schedule) and physical aspects of health‐related quality of life [SF‐36 Physical Component summary Score scale (PCS)]. Six months later subjects completed the SF‐36 PCS and the number of healthcare contacts during follow‐up was recorded. Independent predictors of SF‐36 PCS at 6‐month follow‐up were duration of pain [(standardised regression coefficient (β) = −0.18, p = 0.04), HADS score (β) = −0.27, p = 0.003] and back pain related social difficulties (β = −0.42, p < 0.0005). Number of healthcare contacts over the 6 months ranged from 1 to 29, and was independently predicted by perceived cause of pain [Incident Rate Ratio (IRR) = 1.46, p = 0.03], Fear Avoidance Beliefs about work (IRR = 1.02, p = 0.009) and back pain related social difficulties (IRR = 1.16, p = 0.03). To conclude, anxiety, depression, fear avoidance beliefs relating to work and back pain related stresses predict impairment in subsequent physical health‐related quality of life and number of healthcare contacts. Interventions targeting these psychosocial variables in clinic patients may lead to improved quality of life and healthcare costs

Receiving Preferred Treatment not Associated with Positive Outcome in a Randomized Trial

Background: In a randomized trial of treatments for chronic widespread pain (CWP), participants were asked their treatment preference just prior to randomisation (baseline). This analysis examined whether treatment preference was associated with baseline factors and whether receiving a preferred treatment affected outcomes. Methods: The MUSICIAN trial was a 2 × 2 randomized trial of cognitive behavioural therapy (CBT) or exercise for people with CWP. Participants were randomly allocated to one of three active treatments [CBT (n = 112), exercise (n = 109), both exercise and CBT (n = 112)] or usual care (n = 109). Before allocation participants were asked, if they had a choice, which active treatment they would choose. A positive outcome was self-reported improvement in health of much or very much better 6, 9 and 30 months after entering the study. Associations between preference and baseline characteristics were examined, including age, gender, chronic pain grade (CPG), passive and active coping, fatigue, psychological distress, sleep problems and kinesiophobia. Differences in gender and CPG between preferences were tested by chi-square tests. For continuous variables, comparison was by analysis of variance and, where a difference was observed, Tukey’s honest significant difference was used to identify which preferences differed and then the standardized mean difference (d) with 95% CIs were calculated. Among those allocated to active treatments, logistic regression was used to calculate odds ratios, adjusted for factors associated with preference, with 95% CIs of positive outcome in those receiving their preferred treatment and not receiving preferred treatment as the referent group. Results: Of 442 participants, 144 (33%) expressed preference for exercise, 20 (5%) for CBT, 199 (45%) for combined exercise and CBT and 79 (18%) expressed no preference. Compared with females, males were more likely to prefer exercise only (44 vs 28%) and less likely to prefer combined treatment (35 vs 50%). Those preferring CBT, compared with those preferring exercise, were higher in passive coping [d = 0.9 (95% CI 0.41, 1.37)], fatigue [0.8 (0.34, 1.31)], psychological distress [0.7 (0.26, 1.21)], sleep problems [0.7 (0.18, 1.12)] and kinesiophobia [0.6 (0.17, 1.12)]. Those preferring CBT also had greater scores on passive coping than those preferring combined treatment [0.6 (95% CI 0.11, 1.03)] or no preference [0.5 (−0.01, 0.98)] and greater kinesiophobia than those with no preference [0.5 (−0.05, 0.95)]. Of participants allocated to CBT, exercise or combined treatment, 7, 39 and 50%, respectively, had a preference for their allocated treatment. There was no clear association between achieving a positive outcome and whether or not someone received their preferred treatment (see Table 1). Conclusion: Exercise and exercise combined with CBT were the most preferred treatments. Participants with specific preferences differed from each other with respect to factors which might influence outcome. However, receiving preferred treatment did not appear to influence treatment response. Disclosure statement: M.B. has received funding for the MUSICIAN Study from Arthritis Research UK.

The impact of prior care experience on nursing students' compassionate values and behaviours: A mixed methods study

Background: Compassion is critical to the provision of high-quality healthcare and is foregrounded internationally as an issue of contemporary concern. Paid care experience prior to nurse training has been suggested as a potential means of improving compassion, which has been characterised by the values and behaviours of care, compassion, competence, communication, courage, and commitment. There is however a dearth of evidence to support the effectiveness of prior care experience as a means of improving compassion in nursing. Objective: To explore the impact of paid prior care experience on the values and behaviours of pre-registration nursing students indicated as characterising compassionate care. Design: Longitudinal mixed methods design employing a modified concurrent triangulation strategy, comprising two work packages. Work package 1 was qualitative, and work package 2 adopted a concurrent embedded strategy with a dominant quantitative component. Research is reported in accordance with the Good Reporting of a Mixed Methods Study framework. Setting(s): Three United Kingdom universities. Participants: Pre-registration nursing students attending one of three universities, and individuals who had previously participated in a Health Education England paid prior care experience pilot. Participant numbers at time point 1 were questionnaires n = 220, telephone interviews n = 10, and focus groups n = 8. Methods: Work package 1 consisted of longitudinal semi-structured telephone interviews. Work package 2 comprised validated online questionnaires measuring emotional intelligence, compassion satisfaction and fatigue, resilience, psychological empowerment, and career commitment (as proxies of compassionate values and behaviours), and focus groups. Qualitative data were thematically analysed. Quantitative data were analysed via Analysis of Variance in SPSS v 26. Results: Qualitative findings suggest that prior care experience has both positive and negative effects on students' compassionate values and behaviours, however positive effects do not extend to qualification. No statistically significant differences were found in any of the quantitative outcome measures between participants with and without paid prior care experience. A statistically significant increase in compassion fatigue was identified in both groups of participants post-qualification. Paid prior care experience did not prevent participants from experiencing reality shock on becoming a student or on qualification. Conclusions: There is insufficient evidence of longitudinal beneficial impact to recommend paid prior care experience as an effective intervention to foster nursing students' compassionate values and behaviours. These findings do not support mandating a period of paid care experience as a prerequisite for entry into nurse education. Registration: N/A.

Inflation and Dark Energy from spectroscopy at z > 2

The expansion of the Universe is understood to have accelerated during two epochs: in its very first moments during a period of Inflation and much more recently, at z < 1, when Dark Energy is hypothesized to drive cosmic acceleration. The undiscovered mechanisms behind these two epochs represent some of the most important open problems in fundamental physics. The large cosmological volume at 2 < z < 5, together with the ability to efficiently target high-$z$ galaxies with known techniques, enables large gains in the study of Inflation and Dark Energy. A future spectroscopic survey can test the Gaussianity of the initial conditions up to a factor of ~50 better than our current bounds, crossing the crucial theoretical threshold of $\sigma(f_{NL}^{\rm local})$ of order unity that separates single field and multi-field models. Simultaneously, it can measure the fraction of Dark Energy at the percent level up to $z = 5$, thus serving as an unprecedented test of the standard model and opening up a tremendous discovery space

International patient and physician consensus on a psoriatic arthritis core outcome set for clinical trials

© 2017 Published by the BMJ Publishing Group Limited. Objective To identify a core set of domains (outcomes) to be measured in psoriatic arthritis (PsA) clinical trials that represent both patients' and physicians' priorities. Methods We conducted (1) a systematic literature review (SLR) of domains assessed in PsA; (2) international focus groups to identify domains important to people with PsA; (3) two international surveys with patients and physicians to prioritise domains; (4) an international face-To-face meeting with patients and physicians using the nominal group technique method to agree on the most important domains; and (5) presentation and votes at the Outcome Measures in Rheumatology (OMERACT) conference in May 2016. All phases were performed in collaboration with patient research partners. Results We identified 39 unique domains through the SLR (24 domains) and international focus groups (34 domains). 50 patients and 75 physicians rated domain importance. During the March 2016 consensus meeting, 12 patients and 12 physicians agreed on 10 candidate domains. Then, 49 patients and 71 physicians rated these domains' importance. Five were important to >70% of both groups: musculoskeletal disease activity, skin disease activity, structural damage, pain and physical function. Fatigue and participation were important to >70% of patients. Patient global and systemic inflammation were important to >70% of physicians. The updated PsA core domain set endorsed by 90% of OMERACT 2016 participants includes musculoskeletal disease activity, skin disease activity, pain, patient global, physical function, health-related quality of life, fatigue and systemic inflammation. Conclusions The updated PsA core domain set incorporates patients' and physicians' priorities and evolving PsA research. Next steps include identifying outcome measures that adequately assess these domains

Lifestyle domains as determinants of wheeze prevalence in urban and rural schoolchildren in Ecuador: cross sectional analysis.

BACKGROUND: The acquisition of a modern lifestyle may explain variations in asthma prevalence between urban and rural areas in developing countries. However, the effects of lifestyle on asthma have been investigated as individual factors with little consideration given to the effects of lifestyle as a set of attributes. The aim of the present study was to identify modern lifestyle domains and assess how these domains might explain wheeze prevalence in urban and rural areas. METHODS: We analysed data from cross-sectional studies of urban and rural schoolchildren in Esmeraldas Province, Ecuador. Variables were grouped as indicators of socioeconomic factors, sedentarism, agricultural activities and household characteristics to represent the main lifestyle features of the study population. We used multiple correspondence analyses to identify common lifestyle domains and cluster analysis to allocate children to each domain. We evaluated associations between domains and recent wheeze by logistic regression. RESULTS: We identified 2-3 lifestyle domains for each variable group. Although wheeze prevalence was similar in urban (9.4%) and rural (10.3%) schoolchildren, lifestyle domains presented clear associations with wheeze prevalence. Domains relating to home infrastructure (termed transitional, rudimentary, and basic urban) had the strongest overall effect on wheeze prevalence in both urban (rudimentary vs. basic urban, OR = 2.38, 95% CI 1.12-5.05, p = 0.024) and rural areas (transitional vs. basic urban, OR = 2.02, 95% CI 1.1-3.73, p = 0.024; rudimentary vs. basic urban, OR = 1.88, 95% CI 1.02-3.47, p = 0.043). A high level of sedentarism was associated with wheeze in the rural areas only (OR = 1.64, 95% CI 1.23-2.18, p = 0.001). CONCLUSIONS: We identified lifestyle domains associated with wheeze prevalence, particularly living in substandard housing and a high level of sedentarism. Such factors could be modified through programmes of improved housing and education. The use of lifestyle domains provides an alternative methodology for the evaluation of variations in wheeze prevalence in populations with different levels of development
