Age-Related Patterns in Cancer Pain and Its Psychosocial Impact: Investigating the Role of Variability in Physical and Mental Health Quality of Life.

Age-related patterns in cancer pain remain equivocal. Most studies ignore heterogeneity across multiple domains of well-being, and the potential role of physical (PH) and mental health (MH) quality of life (QOL) in these age-related patterns is unknown. We investigated the relationships between age and cancer pain intensity, qualities, and interference, and physical and psychosocial adaptation and the interaction between age and PH and MH QOL on pain and adaptation to cancer pain. In this cross-sectional study, 244 patients with advanced cancer and pain completed measures of pain, QOL, physical function, and psychosocial well-being. Pearson's correlations and ANOVAs assessed relationships between age and demographic and clinical factors, pain, and physical and psychosocial measures. Regression models tested the role of age and its interaction with PH and MH QOL on pain and physical and psychosocial adaptation. Older age was associated with a lower likelihood of receiving an opioid prescription, greater likelihood of having comorbidities, and worse functional status. When we did not account for these factors, age was not associated with pain and most adaptation indices. When we did account for these factors and PH QOL, older age was associated with lower non-neuropathic and neuropathic pain and several indices of psychosocial adaptation. Most interestingly, older age was associated with lower non-neuropathic pain among those with high, but not low, MH QOL. This study addresses knowledge gaps about factors underlying age-related patterns in cancer pain. Impaired MH QOL may be a proxy for age-related patterns in cancer pain. This study investigated age-related patterns in the experience of cancer pain and the role of quality of life in resilience and vulnerability to pain and adaptation to pain. Older age is associated with lower non-neuropathic pain among those with high, but not low, mental health quality of life, suggesting that impaired mental health quality of life is an important indicator of vulnerability to multidimensional pain outcomes.

SA58. The First-Episode Psychosis Outcome Study: Preliminary Data on the Long-Term Follow-Up of First-Episode Psychosis Patients Who Were Treated at the Early Psychosis Prevention and Intervention Centre Between 1998 and 2000

Abstract Background: Specialist early intervention (SEI) service models are designed to treat symptoms, promote social and vocational recovery, prevent relapse, and resource and up skill patients and their families. While the immediate benefits of SEI are clear, and have been demonstrated, the long-term impact of SEI on illness course is less clear. The First Episode Outcome Study involves the long-term follow-up of a representative sample of first-episode psychosis patients who were treated at the Early Psychosis Prevention and Intervention Centre (EPPIC) between 1998 and 2000. The aim of this presentation is 3-fold: (1) to describe the methodology of FEPOS long-term follow-up; (2) to present preliminary mortality data; and (3) examine the preliminary characteristics of those who have been contacted and interviewed. Methods: Between January 1998 and December 2000, 661 patients between the ages of 15 and 29 years were treated at the Early Psychosis Prevention and Intervention Centre, Melbourne, Australia. The 18-month treatment characteristics of this cohort have been extensively examined in the FEPOS. The long-term outcomes of this cohort are now being examined in a new study (known as FEPOS15). Results: Characteristics of 46 individuals who are deceased will be described. The clinical, functional, physical health, and quality-of-life characteristics of the first 100 individuals who have been contacted will also be discussed. Conclusion: This follow-up study is one of the longest, largest, and most comprehensive studies of the multidimensional outcomes of an SEI service for psychosis.

Improvements in Health-Related Quality of Life, Cardio-Metabolic Health, and Fitness in Postmenopausal Women After an Exercise Plus Health Promotion Intervention: A Randomized Controlled Trial.

This study explored multidimensional outcomes that were derived from the adherence to regular exercise among previously sedentary postmenopausal 45 to 64 years old women who engaged in a ~20-week exercise program. A randomized controlled trial with between-group (intervention and control women) and within-subject measures (baseline, postintervention, and 3-month and 12-month follow-ups) was conducted. HRQoL and several indicators of cardio-metabolic status and fitness were assessed. After the intervention, the participants experienced a positive change in their short and long-term physical and mental health, with significant enhancements in several HRQoL dimensions, particularly mental well-being (23.3% of change) and menopause-related health and subdomains (17.0% of change) (P < .01). Improvements were maintained or continued (eg, mental well-being) overtime. These outcomes were accompanied by significant improvements in cardio-metabolic status and fitness, including weight, BMI, cardio-respiratory fitness and flexibility (up to 16.2% of change, P < .05). After the intervention, the intervention group exhibited better HRQoL than the control group at each of the measurement phases. Between-group differences were also observed for some indicators of cardiovascular health and flexibility. Our findings add evidence on the association of positive outcomes on HRQoL with improvements in cardio-metabolic health and fitness status after the adoption of an active lifestyle.

Outcome of L5 radiculopathy after reduction and instrumented transforaminal lumbar interbody fusion of high-grade L5-S1 isthmic spondylolisthesis and the role of intraoperative neurophysiological monitoring.

To evaluate the incidence and course of iatrogenic L5 radiculopathy after reduction and instrumented fusion of high-grade L5-S1 isthmic spondylolisthesis and the role of intraoperative neurophysiological monitoring (IONM). Consecutive patients treated for high-grade spondylolisthesis with IONM from 2005 to 2013 were screened for eligibility. Prospectively collected clinical and surgical data as well as radiographic outcomes were analyzed retrospectively. Patients completed the multidimensional Core Outcome Measures Index (COMI) before and at 3, 12, and 24months after surgery. Seventeen patients were included, with a mean age of 26.3 (±9.5) years. Mean preoperative L5-S1 slip was 72% (±21%) and was reduced to 19% (±13%) postoperatively. Mean loss of reduction at last follow-up [mean 19months (±14, range 3-48months)] was 3% (±4.3%). Rate of new L5 radiculopathy with motor deficit (L5MD) after surgery was 29% (five patients). Four patients fully recovered after 3months, one patient was lost to neurologic follow-up. IONM sensitivity and specificity for postoperative L5MD was 20 and 100%, respectively. COMI, back pain and leg pain scores showed significant (p<0.001) improvements at 3months postoperatively, which were retained up to 24months postoperatively. Transient L5 radiculopathy after reduction and instrumented fusion of high-grade spondylolisthesis is frequent. With IONM the risk of irreversible L5 radiculopathy is minimal. If IONM signal changes recover, full clinical recovery is expected within 3months. Overall, patient-reported outcome of reduction and instrumented fusion of high-grade spondylolisthesis showed clinically important improvement.

Development of the clinically adaptive multidimensional outcome survey

Objective: Routine outcome monitoring (ROM) has been strongly endorsed by psychotherapy researchers, but has yet to achieve widespread implementation in clinical settings. This article describes the development of the Clinically Adaptive Multidimensional Outcome Survey (CAMOS), an innovative ROM system that allows for local adaptation while providing high quality data. Method: Three-hundred and four clients at a university counseling center and 211 female patients at an eating disorder treatment facility were administered the CAMOS at intake, and 118 took the CAMOS at both intake and discharge. Two models were developed and compared. Both models were developed using exploratory and confirmatory factor analysis. Results: A five-factor model was found to have the best model fit, internal consistency, convergent validity, and discriminant validity. Conclusions: The CAMOS has evidence to support its reliability and validity as a measure of various dimensions of distress. Distinctive tailoring features of the CAMOS compared to other ROM measures are described.

On accommodating spatial interactions in a Generalized Heterogeneous Data Model (GHDM) of mixed types of dependent variables

We develop an econometric framework for incorporating spatial dependence in integrated model systems of latent variables and multidimensional mixed data outcomes. The framework combines Bhat's Generalized Heterogeneous Data Model (GHDM) with a spatial (social) formulation to parsimoniously introduce spatial (social) dependencies through latent constructs. The applicability of the spatial GHDM framework is demonstrated through an empirical analysis of spatial dependencies in a multidimensional mixed data bundle comprising a variety of household choices – household commute distance, residential location (density) choice, vehicle ownership, parents’ commute mode choice, and children's school mode choice – along with other measurement variables for two latent constructs – parent's safety concerns about children walking/biking to school and active lifestyle propensity. The GHDM framework identifies an intricate web of causal relationships and endogeneity among the endogenous variables. Furthermore, the spatial (social) version of the GHDM model reveals a high level of spatial (social) dependency in the latent active lifestyle propensity of different households and moderate level of spatial dependency in parents’ safety concerns. Ignoring spatial (social) dependencies in the empirical model results in inferior data fit, potential bias and statistical insignificance of the parameters corresponding to nominal variables, and underestimation of policy impacts.

Occipital nerve stimulation improves the quality of life in medically-intractable chronic cluster headache: Results of an observational prospective study.

Background Occipital nerve stimulation (ONS) has been proposed to treat chronic medically-intractable cluster headache (iCCH) in small series of cases without evaluation of its functional and emotional impacts. Methods We report the multidimensional outcome of a large observational study of iCCH patients, treated by ONS within a nationwide multidisciplinary network ( https://clinicaltrials.gov NCT01842763), with a one-year follow-up. Prospective evaluation was performed before surgery, then three and 12 months after. Results One year after ONS, the attack frequency per week was decreased >30% in 64% and >50% in 59% of the 44 patients. Mean (Standard Deviation) weekly attack frequency decreased from 21.5 (16.3) to 10.7 (13.8) ( p = 0.0002). About 70% of the patients responded to ONS, 47.8% being excellent responders. Prophylactic treatments could be decreased in 40% of patients. Functional (HIT-6 and MIDAS scales) and emotional (HAD scale) impacts were significantly improved, as well as the health-related quality of life (EQ-5D). The mean (SD) EQ-5D visual analogic scale score increased from 35.2 (23.6) to 51.9 (25.7) ( p = 0.0037). Surgical minor complications were observed in 33% of the patients. Conclusion ONS significantly reduced the attack frequency per week, as well as the functional and emotional headache impacts in iCCH patients, and dramatically improved the health-related quality of life of responders.

The utility of patient-reported outcome measures among patients with myalgic encephalomyelitis/chronic fatigue syndrome.

Debilitating fatigue is a core symptom of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS); however, the utility of patient-reported symptom outcome measures of fatigue for ME/CFS patients is problematic due to ceiling effects and issues with reliability and validity. We sought to evaluate the performance of three patient-reported symptom measures in a sample of ME/CFS patients and matched controls. Two hundred and forty ME/CFS patients and 88 age, sex, race, and zip code matched controls participated in the study. Participants completed the Multidimensional Fatigue Inventory-20, DePaul Symptom Questionnaire, and RAND SF-36. The general and physical fatigue subscales on Multidimensional Fatigue Inventory-20, as well as the role of physical health on the RAND SF-36, demonstrated questionable or unacceptable internal consistency and problematic ceiling effects. The DePaul Symptom Questionnaire demonstrated excellent internal reliability, and less than 5% of participants were at the ceiling on each subscale. The post-exertional malaise subscale on the DePaul Symptom Questionnaire demonstrated excellent clinical utility as it was able to differentiate between ME/CFS patients and controls (OR 1.23, p<.001) and predicted ceiling effects on other patient-reported outcome subscales. A score of 20 on the post-exertional malaise subscale of the DePaul Symptom Questionnaire optimally differentiated between patients and controls. Significant ceiling effects and concerns with reliability and validity were observed among Multidimensional Fatigue Inventory-20 and RAND SF-36 subscales for ME/CFS patients. The DePaul Symptom Questionnaire addresses a number of concerns typically identified when using patient-reported outcome measures with ME/CFS patients; however, an improved multidimensional patient-reported outcome tool for measuring ME/CFS-related symptoms is warranted.

Olympic Champion Sara Simeoni Talks about Gender Barriers in Sport and Medicine: Culture, Opportunities and Resources

An overview of the relationship between elite athletes’ sport activity and medicine was presented during a conference with guest speaker Mrs. Sara Simeoni, Italian Olympic Games high jump champion (one gold medal, in Moscow, and silver medals in Montreal and Los Angeles). She has had a particularly prolonged career for this type of sport activity, and her endorsement and support, since she is a recognized icon of sport excellence, is very important. This is particularly true in relevant and sensitive topics such as gender inequalities, physical exercise and sport ethics. During the conference, the relationship between nutrition, physical activity and health, in both medicine and social life, were also covered. In reality, we still find that the cultural, economic, societal and political barriers are present and, currently, in some regards, they are even stronger than in the past. The interplay between evidence-based medicine, elite athletes’ training, physical fitness practice and physical exercise intervention in health and disease is still being developed. Defining methods and clarifying multidimensional outcomes should, as much as possible, be pursued, and sustainable strategies and tools should be discussed.

Challenges of evaluating a computer-based educational programme for women diagnosed with early-stage breast cancer: a randomised controlled trial.

In a two-group, multi-centre, randomised controlled 9months trial, we (1) evaluated the impact of a computer-based educational programme compared to standard care and (2) examined whether different patterns of programme usage could be explained by demographic, medical and psychosocial factors. We involved 226 Swedish-speaking women diagnosed with early-stage breast cancer and scheduled for surgery. Primary outcomes were health self-efficacy and health care participation measured by the Comprehensive Health Enhancement Supportive System instrument. Secondary outcomes were anxiety and depression levels measured by the Hospital Anxiety and Depression scale. The Functional Assessment of Cancer Therapy-Breast and Sense of Coherence scales measured psychosocial factors for the study's secondary aim. Multi-level modelling revealed no statistically significant impact of the computer-based educational programme over time on the outcomes. Subsequent exploratory regression analysis revealed that older women with axillary dissection and increased physical well-being were more likely to use the programme. Furthermore, receiving post-operative chemotherapy and increased meaningfulness decreased the likelihood of use. Providing reliable and evidence-based medical and rehabilitation information via a computer-based programme might not be enough to influence multi-dimensional outcomes in women diagnosed with breast cancer. The use of these programmes should be further explored to promote adherence to e-Health supportive interventions.

Patient-Rated Outcomes of Lumbar Fusion in Patients With Degenerative Disease of the Lumbar Spine: Does Age Matter?

Single-center retrospective study of prospectively collected data, nested within the Eurospine Spine Tango data acquisition system. The aim of this study was to assess the patient-rated outcome and complication rates associated with lumbar fusion procedures in three different age groups. There is a general reluctance to consider spinal fusion procedures in elderly patients due to the increased likelihood of complications. Before and at 3, 12, and 24 months after surgery, patients completed the multidimensional Core Outcome Measures Index. At the 3-, 12-, and 24-month follow-ups, they also rated the Global Treatment Outcome and their satisfaction with care. Patients were divided into three age groups: younger (≥50 years <65 years; n = 317), older (≥65 years <80 years; n = 350), and geriatric (≥80 years; n = 40). A total of 707 consecutive patients were included. The preoperative comorbidity status differed significantly (P < 0.0001) between the age groups, with the highest scores in the geriatric group. Medical complications during surgery were lower in the younger age group (7%) than in the older (13.4%; P = 0.006) and geriatric groups (17.5%; P = 0.007); surgical complications tended to be higher in the elderly group (younger, 6.3%; older, 6.0%; geriatric, 15.0%; P = 0.09). There were no significant group differences (P > 0.05) for the scores on any of the Core Outcome Measures Index domains, Global Treatment Outcome, or patient-rated satisfaction at either 3-, 12-, and 24-months of follow-up. Despite greater comorbidity and complication rates in geriatric patients, the patient-rated outcome was as good in the elderly as it was in younger age groups up to 2 years after surgery. These data indicate that geriatric age needs careful consideration of associated risks but is not per se a contraindication for fusion for lumbar degenerative disease. 4.

Of apples and oranges: Lessons learned from the preparation of research protocols for systematic reviews exploring the effectiveness of Specialist Palliative Care.

BackgroundAgreed terminology used in systematic reviews of the effectiveness of specialist palliative care ((S)PC)) is required to ensure consistency and usability and to help guide future similar reviews and the design of clinical trials. During the preparation of protocols for two separate systematic reviews that aimed to assess the effectiveness of SPC, two international research groups collaborated to ensure a high degree of methodological consensus and clarity between reviews. During the collaboration, it became evident that close attention is needed to (i) avoid ambiguity in the definition of advanced illness, (ii) capture the specialist expertise and prerequisites for SPC interventions, and (iii) the multi-professional and multi-dimensional nature of PC. Also, (iv) the exclusion of relevant studies or (v) impracticality of meta-analyses of the obtained data must be avoided.The aim of this article is to present the core issues of the discussion to help future research groups to easily identify potential pitfalls and methodologic necessities.Core issue discussionCore issues that arose from the discussion are presented along the research questions according to the PICO process:Population (P): Authors should refer to existing definitions of PC to ensure that, even if the review aims to investigate specific patients (e.g. cancer patients), it is important to make clear that PC is applicable for all life-limiting diseases and not limited to end-of-life or cancer.Intervention (I): PC is a core responsibility of all disciplines (general PC). In contrast, SPC demands further training and expertise. Therefore, core tenets of SPC interventions are that they are (i) multi-professional and (ii) aim at the multi-dimensional nature of suffering.Outcome (O): The main goal of PC is multi-dimensional (quality of life, suffering or distress). Yet, meta-analysis may be complex to conduct due to the heterogeneity of the multi-dimensional outcomes. Therefore, the assessment of uni-dimensional measures such as pain can also provide clinically relevant information that is easier to obtain.Discussion and conclusionRecommendations for future systematic reviews and clinical trials include: (i) Appraise the experience of other research groups who have produced similar systematic reviews or clinical trials.(ii) Include studies that meet the multi-professional and multi-dimensional nature of PC and the specialization requirements for SPC.(iii) Thoroughly weigh relevance and practicability of the primary outcome. Multi-dimensional tools such as quality-of-life questionnaires assess the different dimensions of suffering (the true scope of PC), but uni-dimensional measures such as pain are easier to assess in meta-analyses.

A mixed methods study of knee confidence and self-efficacy: perceptions of knee osteoarthritis patients from the good life with osteoarthritis in Denmark initiative

Purpose: The Good Life with osteoArthritis in Denmark (GLA:D) Initiative is an evidence-based treatment programme for patients with knee and hip osteoarthritis (OA). It incorporates training physiotherapists to deliver care in accordance with the clinical guidelines by educating patients on their condition and by delivering supervised neuromuscular exercises to relieve pain and improve function. The importance of self-efficacy, and confidence in exercise, to exercise adherence has not been reported for the GLA:D population. In addition, worse knee confidence in people with knee OA is associated with higher pain and greater perceived knee instability. The aims of this study were to investigate the association between knee confidence and self-efficacy in patients with knee OA in the GLA:D registry; and to explore patients’ perception of their experiences with the GLA:D programme, and whether confidence and self-efficacy has a role to play in continuing with the GLA:D exercises in the long-term. Methods: This study used a mixed methods design. Patients with knee OA who were offered at least two educational sessions and six weeks of GLA:D exercise programme between January–March 2015 were identified from the GLA:D registry (n = 484) and sent an online survey. Ordinal regression analyses were performed. Knee confidence, assessed using the Knee injury and Osteoarthritis Outcomes Score (KOOS; quality of life subscale, question 3), was the dependent variable and self-reported measures for exercise self-efficacy; arthritis self-efficacy; multidimensional outcomes expectations for exercise; and KOOS pain and activities of daily living (ADL) were the independent variables. Knee confidence score ranged from 0–4 with 0 indicating higher knee confidence. The independent variables ranged from 0–10 or 0–100 with 0 indicating worse symptoms or confidence. Subsequently, semi-structured interviews (n = 4) were used to explore patients’ perceived confidence and adherence to the GLA:D exercises. Interviews were transcribed verbatim, and analysed using interpretative phenomenological analysis. Results: 200 patients (41.3%) responded to the survey. At 7–10 months following treatment initiation, 9.5% of patients were not at all troubled by lack of knee confidence; 39.5% were mildly troubled; 31.5% were moderately troubled; 15.5% were severely troubled; and 4% were extremely troubled. Patients with higher arthritis self-efficacy score were more likely to have higher knee confidence (odds ratio [OR] = 0.76; 95% confidence interval [CI] 0.63, 0.93; P = 0.007). Patients with higher KOOS ADL score were more likely to have higher knee confidence, although this association was small (OR = 0.96; 95% CI 0.93, 0.99; P = 0.006). No association was found between knee confidence and exercise self-efficacy (OR = 1.00; 95% CI 0.99, 1.01; P = 0.90). Patients reflected on seeing great improvements in their confidence, pain and mobility with the programme. They felt their symptoms got worse if they did not keep up with the exercises. Patients reflected on the importance of continued contact with their physiotherapist after the 6-week programme for further motivation and reassurance. One of the barriers that discouraged patients from continuing with the exercises in the long-term was the cost for additional GLA:D exercise classes with their physiotherapist. Conclusions: Patients are troubled by the lack of knee confidence after the GLA:D exercise programme; they reflected this was due to their negative experiences prior to entering the GLA:D programme. Arthritis self-efficacy and KOOS ADL were significantly associated with knee confidence, but no association was found with exercise self-efficacy. Patients from the interview reflected that maintaining contact with their physiotherapist was an important factor to motivate them to continue exercising.

Recovery Curves for Pediatric Burn Survivors: Advances in Patient-Oriented Outcomes.

Patient-reported outcomes serving as benchmarks for recovery of pediatric burn survivors are lacking, and new approaches using longitudinal cohorts for monitoring their expected recovery based on statistical models are needed for patient management during the early years following the burn. To describe multidimensional patient-reported outcomes among pediatric burn survivors younger than 5 years to establish benchmarks using recovery curve methods. Prospective cohort study of pediatric burn survivors younger than 5 years at 12 burn centers. Age-matched nonburned reference groups were studied to define expected results in normal growth and development. The Burn Outcomes Questionnaire for children aged 0 to 5 years (BOQ0-5) was administered to parents of children who had burns and were younger than 5 years. Mixed models were used to generate 48-month recovery curves for each of the 10 BOQ0-5 domains. The study was conducted between January 1999 and December 2008. The 10 BOQ0-5 domains including play, language, fine motor skills, gross motor skills, emotional behavior, family functioning, pain/itching, appearance, satisfaction with care, and worry/concern up to 48 months after burn injury. A total of 336 pediatric burn survivors younger than 5 years (mean [SD] age, 2.0 [1.2] years; 58.4% male; 60.2% white, 18.6% black, and 12.0% Hispanic) and 285 age-matched nonburned controls (mean [SD] age, 2.4 [1.3] years; 51.1% male; 67.1% white, 8.9% black, and 15.0% Hispanic) completed the study. Predicted scores improved exponentially over time for 5 of the BOQ0-5 domains (predicted scores at 1 month vs 24 months: play, 48.6 vs 52.1 [P = .03]; language, 49.2 vs 54.4 [P < .001]; gross motor skills, 48.7 vs 53.0 [P = .002]; pain/itching, 15.8 vs 33.5 [P < .001]; and worry/concern, 31.6 vs 44.9 [P < .001]). Pediatric burn survivors had higher scores in language, emotional behavior, and family functioning domains compared with healthy children in later months. This study demonstrates significant deficits in multiple functional domains across pediatric burn survivors compared with controls. Recovery curves can be used to recognize deviation from the expected course and tailor care to patient needs.

Neuro-QoL health-related quality of life measurement system: Validation in Parkinson's disease.

Neuro-QoL is a multidimensional patient-reported outcome measurement system assessing aspects of physical, mental, and social health identified by neurology patients and caregivers as important. One of the first neurology-specific patient-reported outcome measure systems created using modern test development methods, Neuro-Qol enables brief, yet precise, assessment and the ability to conduct both PD-specific and cross-disease comparisons. We present results of Neuro-QoL clinical validation using a sample of PD patients. A total of 120 PD patients recruited from academic medical centers were assessed at baseline, 1 week, and 6 months. Assessments included Neuro-QoL and general and PD-specific validity measures. Participants were 62% male and 95% white (average age = 66); H & Y stages were 1 (16%), 2 (61%), 3 (18%), and 4 (5%). Internal consistency and test-retest reliability of Neuro-QoL ranged from Cronbach's alphas = 0.81 to 0.94 with intraclass correlation coefficients = 0.66 to 0.80. Pearson's correlations between Neuro-QoL and legacy measures were generally moderate and in expected directions. UPDRS Part 2 was moderately correlated with Neuro-QoL Upper Extremity and Mobility, respectively (r's = -0.44; -0.59). Parkinson's Disease Questionnaire-39 and Neuro-QoL measures of similar constructs showed strong-to-moderate correlations (r's = 0.70-0.44). Neuro-QoL measures of fatigue, mobility, positive emotion, and emotional/behavioral control showed responsiveness to self-reported change. Neuro-QoL is valid for use in PD clinical research. Reliability for all but two measures is sufficient for group comparisons, with some evidence supporting responsiveness to change. Neuro-QoL possesses characteristics, such as brevity, flexibility in administration, and suitability, for cross-disease comparisons that may be advantageous to users in a variety of settings. © 2016 Movement Disorder Society.

Depressive, anxiety and posttraumatic stress disorders as long-term sequelae of intensive care treatment

Modern intensive care medicine has led to increased survival rates even after severe life-threatening medical conditions. In self-critical and multidimensional outcome research, however, it must be considered that beyond survival rates treatment on intensive care units (ICU) can also be associated with high long-term rates of depressive, anxiety and posttraumatic stress disorders. Significant correlations with increased somatic morbidity and mortality, persisting cognitive impairments and significant deficits in health-related quality of life must also be taken into consideration. Empirical analysis of the risk factors reveals that a history of premorbid depression, sociodemographic and socioeconomic variables, age, female sex, personality traits, the underlying pathophysiological condition requiring ICU treatment, mode of sedation and analgesia, life support measures, such as mechanical ventilation, manifold traumatic experiences and memories during the stay in the ICU are all of particular pathogenetic importance. In order to reduce principally modifiable risk factors several strategies are illustrated, including well-reflected intensive care sedation and analgesia, special prophylactic medication regarding the major risk of traumatic memories and posttraumatic stress disorder (PTSD), psychological and psychotherapeutic interventions in states of increased acute stress symptoms and aids for personal memories and reorientation.

Abstract WMP1: Factors Influencing Differential Outcomes in Stent Retriever Trials: Comparison to a new Outcome Model Based on Percent Utilization of rt-PA

Background: While stent-retriever randomized clinical trials (RCTs) were uniformly positive, their designs differed. Here, we assessed whether trials also differed in the magnitude of improvement and if factors could be identified that distinguished the best performers. Because % utilization of rt-PA in the control arms varied, we developed a multi-dimensional outcome model from the control arms of all IV tPA RCTs treating various % of subjects and their baseline stroke severity (NIHSS). This model was used to compare each trial’s functional outcome (mRS &lt; 2) and mortality at their own baseline without need for statistical manipulation. We assessed factors that potentially distinguished the best performers. Methods: The model was developed from 54 RCT control arms representing &gt;11,000 subjects treating between 0-100% with IV rt-PA. 3-D non-linear functions were fit to the 90-day mortality and mRS 0-2. This model includes ±95% statistical interval surfaces to assess whether a trial’s outcomes surpass the variability inherent in a sample of RCT subjects (Neurology 85:274-83, 2015). 6 stent retriever RCTs were compared. Results: The models showed excellent fit: mRS 0-2 (r 2 =0.83, p&lt;&lt;0.001) and mortality (r 2 =0.65, p&lt;&lt;0.001) Figs 1a, 1b. All stent retriever arms exceeded mRS 0-2 +95% surface indicating better than expected efficacy, but the degree of improvement varied: 30-40% absolute improvement over expected outcome was seen in EXTEND and SWIFT-PRIME, compared to 12% for SWIFT and REVASCAT. The 2 top performers had a 75 minute shorter treatment time. Both treated 100% with IV rt-PA compared to SWIFT (33%) and REVASCAT (68%). Conclusion: A new outcome model based on stroke severity and % IV rt-PA permitted analysis of stent-retriever therapy compared to a large population. Best outcomes were related to shorter treatment time and higher utilization of rt-PA, suggesting a treatment interaction between these modalities. Factors influencing mortality are being analyzed.

Influence of previous surgery on patient-rated outcome after surgery for degenerative disorders of the lumbar spine.

Few studies have used multivariate models to quantify the effect of multiple previous spine surgeries on patient-oriented outcome after spine surgery. This study sought to quantify the effect of prior spine surgery on 12-month postoperative outcomes in patients undergoing surgery for different degenerative disorders of the lumbar spine. The study included 4940 patients with lumbar degenerative disease documented in the Spine Tango Registry of EUROSPINE, the Spine Society of Europe, from 2004 to 2015. Preoperatively and 12months postoperatively, patients completed the multidimensional Core Outcome Measures Index (COMI; 0-10 scale). Patients' medical history and surgical details were recorded using the Spine Tango Surgery 2006 and 2011 forms. Multiple linear regression models were used to investigate the relationship between the number of previous surgeries and the 12-month postoperative COMI score, controlling for the baseline COMI score and other potential confounders. In the adjusted model including all cases, the 12-month COMI score showed a 0.37-point worse value [95% confidence intervals (95% CI) 0.29-0.45; p<0.001] for each additional prior spine surgery. In the subgroup of patients with lumbar disc herniation, the corresponding effect was 0.52 points (95% CI 0.27-0.77; p<0.001) and in lumbar degenerative spondylolisthesis, 0.40 points (95% CI 0.17-0.64; p=0.001). We were able to demonstrate a clear "dose-response" effect for previous surgery: the greater the number of prior spine surgeries, the systematically worse the outcome at 12months' follow-up. The results of this study can be used when considering or consenting a patient for further surgery, to better inform the patient of the likely outcome and to set realistic expectations.

Does international experience count in the cross-cultural management course effectiveness?

The rapid increase in globalisation processes in many aspects of social and work life has pushed educators to develop students with cross-cultural competence to work in culturally diverse settings. We extend the current understanding of the effectiveness of cross-cultural management courses by emphasising multidimensional learning outcomes. Furthermore, we investigate the influence of international experience on the effectiveness of cross-cultural management education. By studying 179 students at two universities, our results showed that students' international experience through international student status was positively associated with their cognitive cultural intelligence, and students' international experience through military affiliation was positively related to their motivational cultural intelligence and cross-cultural adjustment efficacy. We discuss ways to utilise experience for better learning and implications for management education.
