Abstract
Rigorous evidence generation with randomized controlled trials has lagged for aneurysmal subarachnoid hemorrhage (SAH) compared with other forms of acute stroke. Besides its lower incidence compared with other stroke subtypes, the presentation and outcome of patients with SAH also differ. This must be considered and adjusted for in designing pivotal randomized controlled trials of patients with SAH. Here, we show the effect of the unique expected distribution of the SAH severity at presentation (World Federation of Neurological Surgeons grade) on the outcome most used in pivotal stroke randomized controlled trials (modified Rankin Scale) and, consequently, on the sample size. Furthermore, we discuss the advantages and disadvantages of different options to analyze the outcome and control the expected distribution of the World Federation of Neurological Surgeons grades in addition to showing their effects on the sample size. Finally, we offer methods that investigators can adapt to more precisely understand the effect of common modified Rankin Scale analysis methods and trial eligibility pertaining to the World Federation of Neurological Surgeons grade in designing their large-scale SAH randomized controlled trials.

Abstract
PURPOSE The modified Rankin Scale (mRS), a clinician-reported outcome measure of global disability, has never been validated in patients with aneurysmal subarachnoid hemorrhage (aSAH). The aims of this study are to assess: (1) convergent validity of the mRS; (2) responsiveness of the mRS; and (3) the distribution of mRS scores across patient-reported outcome measures (PROMs). METHODS This is a prospective randomized multicenter study. The mRS was scored by a physician for all patients, and subsequently by structured interview for half of the patients and by self-assessment for the other half. All patients completed EuroQoL 5D-5L, RAND-36, Stroke Specific Quality of Life scale (SS-QoL) and Global Perceived Effect (GPE) questionnaires. Convergent validity and responsiveness were assessed by testing hypotheses. RESULTS In total, 149 patients with aSAH were included for analysis. The correlation of the mRS with EQ-5D-5L was r = - 0.546, while with RAND-36 physical and mental component scores the correlation was r = - 0.439and r = - 0.574 respectively, and with SS-QoL it was r = - 0.671. Three out of four hypotheses for convergent validity were met. The mRS assessed through structured interviews was more highly correlated with the mental component score than with the physical component score of RAND-36. Improvement in terms of GPE was indicated by 83% of patients; the mean change score of these patients on the mRS was - 0.08 (SD 0.915). None of the hypotheses for responsiveness were met. CONCLUSION The results show that the mRS generally correlates with other instruments, as expected, but it lacks responsiveness. A structured interview of the mRS is best for detecting disabling neuropsychological complaints.

The SOS-SAH questionnaire in clinical practice: a multi-method evaluation study. BMC Neurol 2023; 23:236.

Abstract
BACKGROUND In patients with mild disabilities after aneurysmal subarachnoid hemorrhage (aSAH), invisible symptoms might be easily overlooked during consultations in the outpatient clinic. We hypothesize that the Questionnaire for the Screening of Symptoms in aneurysmal Subarachnoid Hemorrhage (SOS-SAH), a disease-specific patient-reported outcome measure, might aid in screening for symptoms after aSAH. The objective of this explorative study is to evaluate the perceived impact of using the SOS-SAH in daily clinical practice for patients after aSAH, as well as to explore potential barriers to further implementation. METHODS This multi-method study consists of a quantitative and a qualitative component. To evaluate differences in quality of care, a patient experience survey was sent to patients receiving usual care and to patients who received the SOS-SAH. A multiple linear regression model was applied, with the intervention group and case mix adjusters as independent variables. We described differences in the number of symptoms discussed between patients receiving usual care and those receiving care post-implementation. Following implementation, 16 patients and 6 healthcare professionals were interviewed about their perceptions concerning the impact of and barriers to using the SOS-SAH. A thematic analysis was performed to identify the main themes. RESULTS The survey did not reveal any differences between the usual-care group and the post-implementation group on the scales of the patient experience survey. After implementation of the SOS-SAH, the number of symptoms discussed during consultation did not increase. The interviews suggest that the SOS-SAH may improve the preparation of patients by providing them with greater insight into their complaints and by raising issues for the consultation. It could also enhance the structure and efficiency of consultation, in addition to improving communication about issues that matter to patients. All patients and healthcare professionals recommended continuing the use of the SOS-SAH in daily practice. CONCLUSIONS Although no quantitative improvements were found in patient experience and symptoms discussed during consultation, implementation of the SOS-SAH could aid in screening for symptoms in patients after aSAH, and it might have a positive influence on patient preparation, while helping to structure consultations between patients and healthcare professionals.

Abstract
PURPOSE To describe patients' perceived and expected recovery 1 year after aneurysmal subarachnoid hemorrhage (aSAH). MATERIALS AND METHODS Semi-structured interviews were conducted with 16 persons 1 year after aSAH. Inductive manifest qualitative content analysis was used. RESULTS The analysis resulted in two categories and seven subcategories. The category "A spectrum of varying experiences of recovery" includes four subcategories describing physical recovery, mental recovery, alterations in social life, and perceived possibilities to return to normality. Some informants felt that life was almost as before, while others described a completely different life, including a new view of self, altered relationships, not being able to return to work, and effects on personal finances. The category "A spectrum of reflections and expectations of recovery" comprises three subcategories depicturing that expectations of recovery were influenced by existential thoughts, describing what they based own expectations of recovery on, and how expectations from others influenced them. CONCLUSIONS aSAH was perceived as a life-changing event. The changes impacted on informants' view of self and relationships, and they perceived new barriers in their living conditions. Lack of information on expected recovery was expressed and expectations of recovery were at times unrealistic.IMPLICATIONS FOR REHABILITATIONContracting an aneurysmal subarachnoid hemorrhage (aSAH) is a life-changing event with possible impact on a variety of areas in daily life.There is a need for improved information to aSAH survivors and their significant others on the course of the recovery and possible long-term consequences.aSAH survivors may need assistance to balance unrealistic expectations on recovery.

Abstract
Introduction Survivors of an acute subarachnoid hemorrhage (aSAH) may suffer from a long-term neurological disability, cognitive impairment, anxiety, and depression, which can also be related to post-intensive care syndrome (PICS). The aim of this study was to examine the prevalence of PICS symptoms in post-intensive care (ICU) aftercare aSAH patients. Methods We conducted an observational cohort study in aSAH patients from a post-ICU aftercare clinic (ICU-AC). PICS symptoms were evaluated using the Impact of Event Scale-Revised (IES-R), Hospital Anxiety and Depression Scale (HADS), and a medical questionnaire for physical and cognitive functioning. Results A total of 110 patients were included. The prevalence of anxiety and depressive symptoms was 23.6% and 19.1%, respectively. Post-traumatic stress disorder (PTSD) was seen in 26.4%. Cognitive complaints were lack of concentration (63.6%), short-term memory loss (45.8%), and reduced speed of thinking (60.9%). The most reported physical complaints were fatigue (73.6%), limitations in daily activity (72.7%), muscle weakness (41.8%), pain (36.4%), and weight loss (30.9%). PICS symptoms related to all three domains were present in 30% of patients. Conclusion The prevalence of PICS in patients after aSAH is high. Even in patients without aSAH-related neurological impairment who were discharged home, a high prevalence of PICS symptoms was reported. Early screening for PICS should comprise all three domains and is important to facilitate a better tailored rehabilitation of these patients.

Abstract
There has been limited new high-level evidence generated to guide aneurysmal subarachnoid hemorrhage (aSAH) management in the past decade. The choice of outcome measures used in aSAH clinical trials may be one of the factors hindering progress. In this narrative review we consider the current process for determining “what” to measure in aSAH and identify some of the shortcomings of these approaches. A consideration of the unique clinical course of aSAH is then discussed and how this impacts on selecting the best timepoints to assess change in the chosen constructs. We also review the how to critically appraise different measurement instruments and some of the issues with how these are applied in the context of aSAH. We conclude with current initiatives to improve outcome selection in aSAH and future directions in the research agenda.
