Time and predictors of time to treatment for aneurysmal subarachnoid haemorrhage (aSAH): a systematic review

Comfort nursing theory on the postoperative rehabilitation quality and nursing satisfaction of patients with intracranial aneurysm

To explore the influence of comfort nursing theory on the postoperative rehabilitation quality of patients with intracranial aneurysms. From October 2017 to December 2022, 315 patients with intracranial aneurysms underwent interventional surgery in our hospital were included in this retrospective study and divided into the routine group (n = 105) and comfort nursing group (n = 210) based on different nursing methods. The Glasgow Outcome Scale (GOS) was used to assess patient rehabilitation outcomes. Patients' anxiety, pain, quality of life, and their satisfaction with treatment were compared. Compared with the patients receiving routine nursing, the time for comfortable nursing patients to resume normal diet, get out of bed and exercise, and the total hospital stay were significantly shortened. And the GOS score of patients receiving comfort nursing was significantly higher than that of patients receiving routine nursing. After nursing, self-rating anxiety scale and visual analog scale scores of comfortable nursing patients were significantly lower than those of routine nursing, and Karnofsky performance status scores were significantly higher than those of routine nursing. This showed that receiving comfortable nursing was beneficial to improve perioperative anxiety and depression in patients with intracranial aneurysm, and significantly improve the quality of life of patients. The total satisfaction of comfortable nursing patients was 95.24%, while that of routine nursing patients was 76.19%. Complications occurred in 30 patients receiving routine nursing, while only 15 patients received comfort nursing. The immune indexes such as CD3+, CD4+, and CD23+ of comfortable nursing patients were significantly higher than the routine nursing patients within 1 and 5 days after operation, while the immune indexes of CD8+ were lower than the routine nursing patients 5 days after operation. Comfortable nursing from the perspective of quality nursing can significantly improve the physiological indicators of patients with intracranial aneurysms, accelerate the progress of postoperative rehabilitation, improve the anxiety, pain and quality of life of patients, and improve the satisfaction of patients with nursing. Comfort nursing from the perspective of quality nursing can reduce the occurrence of postoperative complications, which may be achieved by improving the patient's immune function.

Pre-treatment re-bleeding following aneurysmal subarachnoid hemorrhage: A systematic review of published prediction models with risk of bias and clinical applicability assessment

BACKGROUND

Pre-treatment rebleeding following aneurysmal subarachnoid hemorrhage (aSAH) increases the risk of death and a poor neurological outcome. Current guidelines recommend aneurysm treatment "as early as feasible after presentation, preferably within 24 h of onset" to mitigate this risk, a practice termed ultra-early treatment. However, ongoing debate regarding whether ultra-early treatment is independently associated with reduced re-bleeding risk, together with the recognition that re-bleeding occurs even in centres practicing ultra-early treatment due to the presence of other risk-factors has resulted in a renewed need for patient-specific re-bleed risk prediction. Here, we systematically review models which seek to provide patient specific predictions of pre-treatment rebleeding risk.

METHODS

Following registration on the International prospective register of systematic reviews (PROSPERO) CRD 42023421235; Ovid Medline (Pubmed), Embase and Googlescholar were searched for English language studies between 1st May 2002 and 1st June 2023 describing pre-treatment rebleed prediction models following aSAH in adults ≥18 years. Of 763 unique records, 17 full texts were scrutinised with 5 publications describing 4 models reviewed. We used the semi-automated template of Fernandez-Felix et al. incorporating the Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies (CHARMS) checklist and the Prediction model Risk Of Bias ASsessment Tool (PROBAST) for data extraction, risk of bias and clinical applicability assessment. To further standardize risk of bias and clinical applicability assessment, we also used the published explanatory notes for the PROBAST tool and compared the aneurysm treatment practices each prediction model's formulation cohort experienced to a prespecified benchmark representative of contemporary aneurysm treatment practices as outlined in recent evidence-based guidelines and published practice pattern reports from four developed countries.

RESULTS

Reported model discriminative performance varied between 0.77 and 0.939, however, no single model demonstrated a consistently low risk of bias and low concern for clinical applicability in all domains. Only the score of Darkwah Oppong et al. was formulated using a patient cohort in which the majority of patients were managed in accordance with contemporary, evidence-based aneurysm treatment practices defined by ultra-early and predominantly endovascular treatment. However, this model did not undergo calibration or clinical utility analysis and when applied to an external cohort, its discriminative performance was substantially lower that reported at formulation.

CONCLUSIONS

No existing prediction model can be recommended for clinical use in centers practicing contemporary, evidence-based aneurysm treatment. There is a pressing need for improved prediction models to estimate and minimize pre-treatment re-bleeding risk.

A case for preference-sensitive decision timelines to aid shared decision-making in intensive care: need and possible application

In the intensive care unit, it can be challenging to determine which interventions align with the patients' preferences since patients are often incapacitated and other sources, such as advance directives and surrogate input, are integral. Managing treatment decisions in this context requires a process of shared decision-making and a keen awareness of the preference-sensitive instances over the course of treatment. The present paper examines the need for the development of preference-sensitive decision timelines, and, taking aneurysmal subarachnoid hemorrhage as a use case, proposes a model of one such timeline to illustrate their potential form and value. First, the paper draws on an overview of relevant literature to demonstrate the need for better guidance to (a) aid clinicians in determining when to elicit patient preference, (b) support the drafting of advance directives, and (c) prepare surrogates for their role representing the will of an incapacitated patient in clinical decision-making. This first section emphasizes that highlighting when patient (or surrogate) input is necessary can contribute valuably to shared decision-making, especially in the context of intensive care, and can support advance care planning. As an illustration, the paper offers a model preference-sensitive decision timeline-whose generation was informed by existing guidelines and a series of interviews with patients, surrogates, and neuro-intensive care clinicians-for a use case of aneurysmal subarachnoid hemorrhage. In the last section, the paper offers reflections on how such timelines could be integrated into digital tools to aid shared decision-making.

2023 Guideline for the Management of Patients With Aneurysmal Subarachnoid Hemorrhage: A Guideline From the American Heart Association/American Stroke Association

AIM

The "2023 Guideline for the Management of Patients With Aneurysmal Subarachnoid Hemorrhage" replaces the 2012 "Guidelines for the Management of Aneurysmal Subarachnoid Hemorrhage." The 2023 guideline is intended to provide patient-centric recommendations for clinicians to prevent, diagnose, and manage patients with aneurysmal subarachnoid hemorrhage.

METHODS

A comprehensive search for literature published since the 2012 guideline, derived from research principally involving human subjects, published in English, and indexed in MEDLINE, PubMed, Cochrane Library, and other selected databases relevant to this guideline, was conducted between March 2022 and June 2022. In addition, the guideline writing group reviewed documents on related subject matter previously published by the American Heart Association. Newer studies published between July 2022 and November 2022 that affected recommendation content, Class of Recommendation, or Level of Evidence were included if appropriate. Structure: Aneurysmal subarachnoid hemorrhage is a significant global public health threat and a severely morbid and often deadly condition. The 2023 aneurysmal subarachnoid hemorrhage guideline provides recommendations based on current evidence for the treatment of these patients. The recommendations present an evidence-based approach to preventing, diagnosing, and managing patients with aneurysmal subarachnoid hemorrhage, with the intent to improve quality of care and align with patients' and their families' and caregivers' interests. Many recommendations from the previous aneurysmal subarachnoid hemorrhage guidelines have been updated with new evidence, and new recommendations have been created when supported by published data.

Impact of Off-Hour Admission with Subarachnoid Hemorrhage: A Meta-Analysis

OBJECTIVE

This meta-analysis assessed the impact of off-hour hospitalization (weekends, and evenings or nighttime on weekdays) on mortality and morbidity in patients with nontraumatic subarachnoid hemorrhage (SAH).

METHODS

Electronic databases were systematically searched for studies comparing outcomes between patients with nontraumatic SAH hospitalized during off-hour and on-hour periods (daytime on weekdays). The primary outcome was mortality (in-hospital and at different follow-up periods after hospitalization). Secondary outcomes included delays in treatment, and complications. Sensitivity analysis including only studies in which adjusted multivariate analyses were performed for any of the outcomes, and meta-regression controlling for clinically important patient factors, were also performed.

RESULTS

Sixteen studies were included. There was no significant difference in in-hospital mortality (adjusted odds ratio, 1.03; 95% confidence interval [CI], 0.97-1.09; P = 0.30) and at all follow-up periods (7/14 days and 1/3/6 months) after hospitalization between SAH patients who were admitted during off-hour compared with on-hour periods, despite adjusted multivariate meta-analysis being performed. However, patients who were admitted during off-hour periods experienced greater delays from their initial scan to treatment (mean difference, 42.7, 25.2-60.1 hours; P < 0.0001) and had higher rates of pneumonia (odds ratio, 1.65, 1.12-2.44; P = 0.011).

CONCLUSIONS

This meta-analysis has not shown an increased risk of mortality in the short-term and long-term among patients with nontraumatic SAH who were hospitalized during off-hour compared with on-hour periods, despite adjusting for potentially confounding patient factors. The delays to treatment and higher observed rates of pneumonia highlight areas in which hospital services and resources should be targeted during these off-hour periods in patients presenting with nontraumatic SAH.

Neurosurgical Admission Later Than 4 h After the Emergency Call Does Not Result in Worse Long-Term Outcome in Subarachnoid Haemorrhage

Background: Few studies have investigated the importance of the time interval between contact to the emergency medical service and neurosurgical admission in patients with spontaneous subarachnoid haemorrhage. We hypothesised that longer time to treatment would be associated with an increased risk of death or early retirement.

Methods: This was a retrospective observational study with 4 years follow-up. Those who reached a neurosurgical department in fewer than 4 h were compared with those who reached it in more than 4 h. Individual level data were merged from the Danish National Patient Register, medical records, the Copenhagen Emergency Medical Dispatch Centre, the Civil Registration System, and the Ministry of Employment and Statistics Denmark. Patients were ≥18 years and had a verified diagnosis of spontaneous subarachnoid haemorrhage. The primary outcome was death or early retirement after 4 years.

Results: Two hundred sixty-two patients admitted within a three-and-a-half-year time period were identified. Data were available in 124 patients, and 61 of them were in their working age. Four-year all-cause mortality was 25.8%. No significant association was found between time to neurosurgical admission and risk of death or early retirement (OR = 0.35, 95% confidence interval [CI]: 0.10–1.23, p = 0.10).

Conclusion: We did not find an association between the time from emergency telephone call to neurosurgical admission and the risk of death or early retirement.
