Management decisions on unruptured intracranial aneurysms before and after implementation of the PHASES score

Knowledge, attitude, practice and illness perception toward subarachnoid hemorrhage prevention and management among intracranial aneurysm patients

OBJECTIVE

This study aims to explore the knowledge, attitude, practice and illness perception toward prevention and management of subarachnoid hemorrhages (SAH) among intracranial aneurysm (IA) patients.

METHODS

A cross-sectional study was conducted between March 2023 and June 2023; demographic characteristics and KAP scores were collected by a self-administered questionnaire and analyzed by linear regression and path analysis.

RESULTS

A total of 455 patients with IA were included, of them 26.37% experienced SAH before. Mean knowledge, attitude and practice scores were 16.60 ± 5.86, 16.39 ± 1.84, and 35.07 ± 3.51, respectively. The linear regression showed ethnic minority, married, education, family members in healthcare system, monthly per capita household income, experience ruptured intracranial aneurysms, smoking, hypertension, hyperlipidemia, diabetes, and aortic lesion were associated with knowledge scores. Age, ethnic minority, urban residence, education, family members in healthcare system, monthly per capita household income, duration of IA ≥6 months, experience ruptured intracranial aneurysms, smoking, diabetes, and aortic lesion were associated with attitude scores. Age, urban residence, monthly per capita household income, duration of IA ≥6 months, experience of ruptured intracranial aneurysms, smoking, diabetes, and aortic lesion were associated with practice scores. According to the path analysis, knowledge directly affected illness perception (β=0.156, P<0.001) and attitude (β=0.708, P<0.001), while attitude (β=0.909, P<0.001) and illness perception (β=0.039, P=0.027) affected practice.

CONCLUSIONS

Patients had positive attitudes towards SAH prevention and management, but a substantial knowledge gap was found along with notably delayed medical help-seeking behavior.

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.

Optimal PHASES Scoring for Risk Stratification of Surgically Treated Unruptured Aneurysms

OBJECTIVE

The PHASES (Population, Hypertension, Age, Size, Earlier subarachnoid hemorrhage, Site) score was developed to facilitate risk stratification for management of unruptured intracranial aneurysms (UIAs). This study aimed to identify the optimal PHASES score cutoff for predicting neurologic outcomes in patients with surgically treated aneurysms.

METHODS

All patients who underwent microneurosurgical treatment for UIA at a large quaternary center from January 1, 2014, to December 31, 2020, were retrospectively reviewed. Inclusion criteria included a modified Rankin Scale (mRS) score of ≤2 at admission. The primary outcome was 1-year mRS score, with a "poor" neurologic outcome defined as an mRS score >2.

RESULTS

In total, 375 patients were included in the analysis. The mean (SD) PHASES score for the entire study population was 4.47 (2.67). Of 375 patients, 116 (31%) had a PHASES score ≥6, which was found to maximize prediction of poor neurologic outcome. Patients with PHASES scores ≥6 had significantly higher rates of poor neurologic outcome than patients with PHASES scores <6 at discharge (58 [50%] vs. 90 [35%], P = 0.005) and follow-up (20 [17%] vs. 18 [6.9%], P = 0.002). After adjusting for age, Charlson Comorbidity Index score, nonsaccular aneurysm, and aneurysm size, PHASES score ≥6 remained a significant predictor of poor neurologic outcome at follow-up (odds ratio, 2.75; 95% confidence interval, 1.42-5.36, P = 0.003).

CONCLUSIONS

In this retrospective analysis, a PHASES score ≥6 was associated with significantly greater proportions of poor outcome, suggesting that awareness of this threshold in PHASES scoring could be useful in risk stratification and UIA management.

Retrospective Application of Risk Scores to Unruptured Anterior Communicating Artery Aneurysms

BACKGROUND

Treatment decisions for unruptured intracranial aneurysms (UIAs) pose a challenge for neurosurgeons, prompting the development of clinical scales assessing hemorrhage risk to provide management guidance. This study compares recommendations from the PHASES and UIA treatment scores (UIATS) applied to anterior communicating artery (AComA) UIAs against real-world management.

METHODS

While UIATS recommends management, for PHASES, an aneurysm with score of 10 or more was considered "high-risk". Analysis involved assessing the concordance in each group alongside comparison to real-word management.

RESULTS

Among 129 patients, 46.5% were observed and 53.5% were treated. PHASES scores were significantly higher in the treatment group (p = 0.00002), and UIATS recommendations correlated with real-world decisions (p < 0.001). We observed no difference in the frequencies of UIATS recommendations between high- and low-risk groups. When comparing the UIATS and PHASES, 33% of high-risk aneurysms received a UIATS conservative management recommendation. In 39% of high-risk aneurysms, the UIATS recommendation was not definitive. Conversely, 27% of low-risk aneurysms obtained a UIATS UIA repair recommendation. Overall, concordance between PHASES and UIATS was 32%.

CONCLUSIONS

Significant discordance in therapeutic suggestions underscores the predominant influence of center experience and individual assessments. Future studies should refine and validate decision-making strategies, potentially exploring alternative applications or developing tailored scales.

Comparison of the unruptured intracranial aneurysm treatment score recommendations with clinical treatment results - A series of 322 aneurysms

Intracranial aneurysms occur with a prevalence of 3-5 %. Subarachnoid hemorrhage (SAH) due to aneurysm rupture is a rare but possibly fatal complication, so that occlusion of unruptured intracranial aneurysms (UIA) must be considered. The Unruptured Intracranial Aneurysm Treatment Score (UIATS) offers support for clinical decision making and has been shown to correlate with real life decisions in clinical practice. However, there is no data concerning the correlation of patient outcome and UIATS. Patients presenting to our outpatient clinic between January 1st, 2014 and December 31st, 2017 were retrospectively analyzed. We recorded the Extended Glasgow Outcome Scale (GOS-E) for longest possible follow-up, the choice of treatment, complications and UIATS recommendation. We included 221 patients with 322 UIA. 124 (38.5 %) UIA were observed and 198 (61.5 %) were occluded, of which 62 (31.3 %) underwent open surgery and 136 (68.7 %) were treated endovascularly. Spearman's rank correlation between our treatment choice and conclusive UIATS recommendation was 0.362 (p < 0.001). If UIATS was inconclusive, there were significantly more treatment-associated deteriorations (10/66 versus 7/132, p = 0.020). Otherwise, UIATS was not significantly associated with outcome. Therefore, treatment choice for UIA remains an individual decision. However, inconclusive UIATS must trigger vigilance and may be a negative prognostic marker for complications.
