Objectives. As a disease typified by early onset and chronic disease course, caring for a person with schizophrenia may have a significant impact on caregivers' lives. This study aimed to investigate the subjective experiences of caregivers of people with schizophrenia as a means of understanding “caregiver burden” in this population. Methods. Face-to-face qualitative interviews were conducted with a diverse sample of 19 US-English speaking caregivers of people with schizophrenia (who were at least moderately ill). Interview transcripts were analyzed using grounded theory methods and findings used to inform the development of a preliminary conceptual model outlining caregivers' experiences. Results. Findings support assertions that people with schizophrenia were largely dependent upon caregivers for the provision of care and caregivers subsequently reported lacking time for themselves and their other responsibilities (e.g., family and work). Caregiver burden frequently manifested as detriments in physical (e.g., fatigue, sickness) and emotional well-being (e.g., depression and anxiety). Conclusions. Caring for a person with schizophrenia has a significant impact on the lives of informal (unpaid) caregivers and alleviating caregiver burden is critical for managing individual and societal costs. Future research should concentrate on establishing reliable and valid means of assessing burden among caregivers of persons with schizophrenia to inform the development and evaluation of interventions for reducing this burden.

The transition from relapsing-remitting multiple sclerosis (RRMS) to secondary progressive multiple sclerosis (SPMS) evolves over time and it can be challenging for physicians to identify progression early. Typically, SPMS is diagnosed retrospectively with a significant delay, based on a history of gradual worsening, independent of relapses, following an initial relapsing-remitting disease course. As such, SPMS is often associated with a considerable period of diagnostic uncertainty. This study aimed to explore and characterize key symptoms and impacts associated with transitioning from RRMS to SPMS and inform the content for a tool to support evaluation of early subtle signs suggestive of progressive disease. Methods: The qualitative study involved 60-min, face-to-face, concept elicitation (CE) interviews with 32 patients with MS (US = 16 and Germany = 16); and 30-min, telephone, CE interviews with 16 neurologists (US = 8 and Germany = 8). Multivariate analysis on data from a real-world observational study of 3294 MS patients assessed the differences between early-RRMS and early-SPMS, and identified factors that were significant drivers of this difference. These studies informed selection of the key variables to be included in a pilot tool. Sixteen physicians used the pilot tool, presented as a paper questionnaire, with a sample of patients whom they suspected were progressing to SPMS (n ≥ 5). Following this, the physicians participated in a 30-min cognitive debriefing (CD) interview to evaluate the relevance and usefulness of the tool. Qualitative analysis of all anonymized, verbatim transcripts was performed using thematic analysis. Results: Patients and physicians reported signs that indicated progression to SPMS including gradual worsening of symptoms, lack of clear recovery, increased severity and presence of new symptoms. No specific symptoms definitively indicated progression to SPMS, however a number of potential symptoms associated with progression were identified by SPMS patients and physicians, including worsening ambulation, cognition, balance, muscle weakness, visual symptoms, bladder symptoms and fatigue. Quality of life domains reported to be more severely impacted in SPMS than MS in general included: physical activity, work, daily activities, emotional and social functioning. Multivariate analysis of the observational study data identified several variables strongly associated with progression to SPMS including, requirement of assistance in daily living, presence of motor symptoms, presence of ataxia/coordination symptoms, and unemployment. Physicians reported that items included in the tool were easy to understand and relevant. Physicians also reported that there is an unmet need for a tool to help identify signs of SPMS progression and so the tool would be useful in clinical practice. Conclusions: This was the first stage of development of a novel, validated, physician-completed tool to support

Background Defining the transition from relapsing-remitting multiple sclerosis (RRMS) to secondary progressive multiple sclerosis (SPMS) can be challenging and delayed. A digital tool (MSProDiscuss) was developed to facilitate physician-patient discussion in evaluating early, subtle signs of multiple sclerosis (MS) disease progression representing this transition. Objective This study aimed to determine cut-off values and corresponding sensitivity and specificity for predefined scoring algorithms, with or without including Expanded Disability Status Scale (EDSS) scores, to differentiate between RRMS and SPMS patients and to evaluate psychometric properties. Methods Experienced neurologists completed the tool for patients with confirmed RRMS or SPMS and those suspected to be transitioning to SPMS. In addition to age and EDSS score, each patient’s current disease status (disease activity, symptoms, and its impacts on daily life) was collected while completing the draft tool. Receiver operating characteristic (ROC) curves determined optimal cut-off values (sensitivity and specificity) for the classification of RRMS and SPMS. Results Twenty neurologists completed the draft tool for 198 patients. Mean scores for patients with RRMS (n=89), transitioning to SPMS (n=47), and SPMS (n=62) were 38.1 (SD 12.5), 55.2 (SD 11.1), and 69.6 (SD 12.0), respectively (P<.001, each between-groups comparison). Area under the ROC curve (AUC) including and excluding EDSS were for RRMS (including) AUC 0.91, 95% CI 0.87-0.95, RRMS (excluding) AUC 0.88, 95% CI 0.84-0.93, SPMS (including) AUC 0.91, 95% CI 0.86-0.95, and SPMS (excluding) AUC 0.86, 95% CI 0.81-0.91. In the algorithm with EDSS, the optimal cut-off values were ≤51.6 for RRMS patients (sensitivity=0.83; specificity=0.82) and ≥58.9 for SPMS patients (sensitivity=0.82; specificity=0.84). The optimal cut-offs without EDSS were ≤46.3 and ≥57.8 and resulted in similar high sensitivity and specificity (0.76-0.86). The draft tool showed excellent interrater reliability (intraclass correlation coefficient=.95). Conclusions The MSProDiscuss tool differentiated RRMS patients from SPMS patients with high sensitivity and specificity. In clinical practice, it may be a useful tool to evaluate early, subtle signs of MS disease progression indicating the evolution of RRMS to SPMS. MSProDiscuss will help assess the current level of progression in an individual patient and facilitate a more informed physician-patient discussion.

Background Presbyopia is defined as the age-related deterioration of near vision over time which is experienced in over 80% of people aged 40 years or older. Individuals with presbyopia have difficulty with tasks that rely on near vision. It is not currently possible to stop or reverse the aging process that causes presbyopia; generally, it is corrected with glasses, contact lenses, surgery, or the use of a magnifying glass. Objective This study aimed to explore how individuals used social media to describe their experience of presbyopia with regard to the symptoms experienced and the impacts of presbyopia on their quality of life. Methods Social media sources including Twitter, forums, blogs, and news outlets were searched using a predefined search string relating to symptoms and impacts of presbyopia. The data that were downloaded, based on the keywords, underwent manual review to identify relevant data points. Relevant posts were further manually analyzed through a process of data tagging, categorization, and clustering. Key themes relating to symptoms, impacts, treatment, and lived experiences were identified. Results A total of 4456 social media posts related to presbyopia were identified between May 2017 and August 2017. Using a random sampling methodology, we selected 2229 (50.0%) posts for manual review, with 1470 (65.9%) of these 2229 posts identified as relevant to the study objectives. Twitter was the most commonly used channel for discussions on presbyopia compared to forums and blogs. The majority of relevant posts originated in Spain (559/1470, 38.0%) and the United States (426/1470, 29.0%). Of the relevant posts, 270/1470 (18.4%) were categorized as posts written by individuals who have presbyopia, of which 37 of the 270 posts (13.7%) discussed symptoms. On social media, individuals with presbyopia most frequently reported experiencing difficulty reading small print (24/37, 64.9%), difficulty focusing on near objects (15/37, 40.5%), eye strain (12/37, 32.4%), headaches (9/37, 24.3%), and blurred vision (8/37, 21.6%). 81 of the 270 posts (30.0%) discussed impacts of presbyopia—emotional burden (57/81, 70.4%), functional or daily living impacts (46/81, 56.8%), such as difficulty reading (46/81, 56.8%) and using electronic devices (21/81, 25.9%), and impacts on work (3/81, 3.7%). Conclusions Findings from this social media listening study provided insight into how people with presbyopia discuss their condition online and highlight the impact of presbyopia on individuals’ quality of life. The social media listening methodology can be used to generate insights into the lived experience of a condition, but it is recommended that this research be combined with prospective qualitative research for added rigor and for confirmation of the relevance of the findings.

BackgroundThe responsibilities of caring for a person with schizophrenia may significantly impact informal caregivers’ lives. The Zarit Burden Interview (ZBI) was originally developed to assess burden among caregivers of people with Alzheimer’s disease.ObjectiveThis research was conducted to inform the development of a revised version of the ZBI, relevant to caregivers of people with schizophrenia.MethodsBased on published qualitative research, the questionnaire was reviewed and modified in accordance with industry-standard guidelines. The resulting questionnaire [the Schizophrenia Caregiver Questionnaire (SCQ)] was then completed by 19 caregivers during cognitive debriefing interviews to assess understanding, relevance and comprehensiveness.ResultsReview of the ZBI resulted in a number of operational changes to improve face validity and potential sensitivity. Further questions were added based on key concepts identified in existing literature and minor phrasing alterations were made to improve content validity. Findings from caregiver interviews supported the content validity of the SCQ.ConclusionThe SCQ provides a comprehensive view of caregivers’ subjective experiences of caregiving and demonstrated strong face and content validity. The questionnaire will be important in both clinical assessment and evaluating the efficacy of interventions designed to reduce or alleviate caregiver burden. Future research will seek to establish the psychometric validity of the questionnaire.

Background There is an unmet need for a tool that helps to evaluate patients who are at risk of progressing from relapsing-remitting multiple sclerosis to secondary progressive multiple sclerosis (SPMS). A new tool supporting the evaluation of early signs suggestive of progression in multiple sclerosis (MS) has been developed. In the initial stage, concepts relevant to progression were identified using a mixed method approach involving regression on data from a real-world observational study and qualitative research with patients and physicians. The tool was drafted in a questionnaire format to assess these variables. Objective This study aimed to develop the scoring algorithm for the tool, using both quantitative and qualitative research methods. Methods The draft scoring algorithm was developed using two approaches: quantitative analysis of real-world data and qualitative analysis based on physician interviews and ranking and weighting exercises. Variables that were included in the draft tool and regarded as most clinically relevant were selected for inclusion in a multiple logistic regression. The analyses were run using physician-reported data and patient-reported data. Subsequently, a ranking and weighting exercise was conducted with 8 experienced neurologists as part of semistructured interviews. Physicians were presented with the variables included in the draft tool and were asked to rank them in order of strength of contribution to progression and assign a weight by providing a percentage of the overall contribution. Physicians were also asked to explain their ranking and weighting choices. Concordance between physicians was explored. Results Multiple logistic regression identified age, MS disease activity, and Expanded Disability Status Scale score as the most significant physician-reported predictors of progression to SPMS. Patient age, mobility, and self-care were identified as the strongest patient-reported predictors of progression to SPMS. In physician interviews, the variables ranked and weighted as most important were stability or worsening of symptoms, intermittent or persistent symptoms, and presence of ambulatory and cognitive symptoms. Across all physicians, the level of concordance was 0.278 (P<.001), indicating a low to moderate, but statistically significant, level of agreement. Variables were categorized as high (n=8), moderate (n=8), or low (n=10) importance based on the findings from the different approaches described above. Accordingly, the respective questions in the tool were assigned a weight of “three,” “two,” or “one” to inform the draft scoring algorithm. Conclusions This study further confirms the need for a tool to provide a consistent, comprehensive approach across physicians to support the early evaluation of signs indicative of progression to SPMS. The novel and comprehensive approach to develop the draft scoring algorithm triangulates data obtained from ranking and weighting exercises, qualitative interviews, and a real-world observational study. Variables that go beyond the clinically most obvious impairment in lower limbs have been identified as relevant subtle/sensitive signs suggestive of progressive disease.

The findings suggest that patients using ReFacto AF with FuseNGo were satisfied with and adherent to their treatment. The HaemoPREF can identify important concepts relating to patient treatment experience in HA.
