Quality of Life Outcomes Over Time in Patients With Unruptured Intracranial Aneurysms With and Without Preventive Occlusion: A Prospective Cohort Study

Impact of Illness Uncertainty on Health-Related Quality of Life in Patients With Unruptured Intracranial Aneurysms After Coil Embolization

ABSTRACT

BACKGROUND: This study aimed to identify the impact of illness uncertainty on physical and mental health-related quality of life (HRQoL) in patients with unruptured intracranial aneurysms (UIAs) after coil embolization. METHODS: A cross-sectional study was conducted and HRQoL was evaluated using the Short Form-12 Health Survey Questionnaire, which assesses physical and mental HRQoL. RESULTS: The participants had a mean age of 56.4 years, and among them, 190 (71.2%) were women. Physical and mental HRQoL were negatively correlated with physical symptoms, anxiety, depression, and illness uncertainty. Mental HRQoL was positively correlated with social support. Physical HRQoL was significantly influenced by depression (β = -0.26, P = .004) and was not influenced by illness uncertainty (β = -0.10, P = .101). Mental HRQoL was significantly influenced by anxiety (β = -0.45, P < .001), depression (β = -0.19, P = .003), social support (β = 0.14, P = .004), and illness uncertainty (β = -0.14, P = .005). The finding that illness uncertainty influences HRQoL suggests a basis for interventions aimed at improving mental HRQoL by reducing illness uncertainty in patients with UIAs. CONCLUSION: The physical and mental HRQoL in patients with UIAs after coil embolization is negatively influenced by depression, whereas mental HRQoL is also affected by anxiety, illness uncertainty, and social support. These results may serve as reference data for the design and development of interventions to improve HRQoL in patients with UIAs after coil embolization.

Scanxiety and quality of life around follow-up imaging in patients with unruptured intracranial aneurysms: a prospective cohort study

OBJECTIVES

Patients with an unruptured intracranial aneurysm (UIA) may experience scanxiety around follow-up imaging. We studied the prevalence and temporal pattern of scanxiety, and compared quality of life (QoL) outcomes in patients with and without scanxiety.

METHODS

We performed a prospective cohort study in a tertiary referral center in the Netherlands between October 2021 and November 2022. We sent questionnaires to patients ≥ 18 years old undergoing UIA follow-up imaging 4 weeks before (T1), immediately after (T2), and 6 weeks after the scan (T3) to assess health-related QoL (HRQoL) and emotional functioning. At T3, we also assessed scanxiety with a purpose-designed questionnaire. We compared differences in QoL outcomes between respondents with and without scanxiety using mixed models.

RESULTS

Of 158 eligible patients, 106 (67%) participated (mean age 61 years ± 11 [standard deviation], 84 women). Sixty of the 91 respondents (66%) who completed the purpose-designed questionnaire experienced scanxiety. Of the 49 respondents who experienced scanxiety after the scan, it resolved in 22 (45%) within a day after receiving the radiology report. HRQoL did not differ between respondents with or without scanxiety. Emotional functioning was worse for respondents with scanxiety (mean Hospital Anxiety and Depression Scale sum score difference at T1, 3.6 [95% CI, 0.9-6.3]; T2, 4.1 [95% CI, 1.5-6.8]; and T3, 4.0 [95% CI, 1.5-6.5]).

CONCLUSIONS

Two-thirds of the respondents experienced scanxiety around follow-up imaging, which often resolved within a day after receiving results. Patients with scanxiety had similar HRQoL but worse emotional functioning compared to patients without scanxiety. The time between the scan and receiving the results should be minimized to decrease the duration of scanxiety.

CLINICAL RELEVANCE STATEMENT

We showed that scanxiety is common in UIA patients, and negatively associated with emotional functioning. Since scanxiety often disappears immediately after receiving the radiology report, it should be communicated to the patient as early as possible to alleviate patients' distress.

KEY POINTS

• Many patients with an unruptured intracranial aneurysm experience emotional distress around follow-up imaging, termed "scanxiety." • Patients with scanxiety had worse emotional functioning compared to patients without scanxiety. • Scanxiety often resolved within a day after receiving the radiology report.

Are diagnoses of unruptured intracranial aneurysms associated with quality of life, psychological distress, health anxiety, or use of healthcare services in untreated individuals? A longitudinal, nested case-control study

Introduction

Increasing imaging examination rates leads to a corresponding rise in the detection rates of unruptured intracranial aneurysms (UIAs). There is limited knowledge on how the detection of UIA affects health-related outcomes in untreated patients.

Research question

Is the diagnosis of UIA associated with psychosocial outcomes, healthcare services utilisation, or sick leave in untreated individuals?

Material and methods

Nested case-control study with 96 participants diagnosed with UIAs through magnetic resonance angiography (MRA) screening, not receiving preventive aneurysm obliteration. Comparisons were made with Control1 (192 participants with negative MRAs) and Control2 (192 individuals not MRA screened). Quality of life, psychological distress, and health anxiety were assessed using EQ-5D-5L including EQ VAS, Hopkins Symptom Checklist-10, and Whiteley Index-6, respectively. Healthcare service utilisation and sick leave was measured using registry data. Median follow-up was 32-55 months for the different outcomes.

Results

UIA were in general not associated with psychosocial outcomes, neither compared to pre-screening values nor to controls. The exemption was a lower mean EQ VAS score at follow-up for cases (76.7) versus Control1 (80.0), regression coefficient -3.87 (95% CI (-7.60, -0.14). Cases had significantly higher rates of radiology exams compared to controls, with 1.47 (95% CI 1.25, 1.74) exams per person-year versus 0.91 (C95% CI 0.75, 1.09) for Control1 and 0.95 (95% CI CI 0.79, 1.14) for Control2. No significant differences were observed in other psychosocial outcomes, healthcare services utilisation, or sick-leave.

Discussion and conclusions

The overall impact of untreated UIAs appears to be limited when assessed years after diagnosis.

Appraising the causal association among depression, anxiety and intracranial aneurysms: Evidence from genetic studies

BACKGROUND

The risk of intracranial aneurysms (IAs) is increased in individuals with depression and anxiety. This indicates that depression and anxiety may contribute to the development of physical disorders. Herein, to investigate the association between genetic variants related to depression and anxiety and the risk of IA, two-sample Mendelian randomization was performed.

METHODS

The genome-wide association study (GWAS) comprised genome-wide genotype data of 2248 clinically well-characterized patients with anxiety and 7992 ethnically matched controls from four European countries. Sex-specific summary-level outcome data were obtained from the GWAS of IA, including 23 cohorts with a total of 10,754 cases and 306,882 controls of European and East Asian ancestry. To improve validity, five varying Mendelian randomization techniques were used in the analysis, namely Mendelian randomization-Egger, weighted median, inverse variance weighted, simple mode, and weighted mode.

RESULTS

The inverse variance weighted results indicated the causal effect of depression on IA (P = 0.03, OR = 1.32 [95 % CI, 1.03-1.70]) and unruptured IA (UIA) (P = 0.02, OR = 1.68 [95 % CI, 1.08-2.61]). However, the causal relationship between depression and subarachnoid hemorrhage (SAH) was not found (P = 0.16). We identified 43 anxiety-associated single-nucleotide polymorphisms as genetic instruments and found no causal relationship between anxiety and IA, UIA, and SAH.

LIMITATIONS

Potential pleiotropy, possible weak instruments, and low statistical power limited our findings.

CONCLUSION

Our MR study suggested a possible causal effect of depression on the increased risk of UIAs. Future research is required to investigate whether rational intervention in depression treatment can help to decrease the societal burden of IAs.

Serial Quality of Life Assessment around Screening for Familial Intracranial Aneurysms: A Prospective Cohort Study

INTRODUCTION

Screening for intracranial aneurysms (IAs) is cost-effective in first-degree relatives of aneurysmal subarachnoid haemorrhage patients, but its psychosocial impact is largely unknown.

PATIENTS AND METHODS

A consecutive series of persons aged 20-70 years visiting the University Medical Centre Utrecht for first screening for familial IA was approached between 2017 and 2020. E-questionnaires were administered at six time points, consisting of the EQ-5D for health-related quality of life (QoL), HADS for emotional functioning, and USER-P for social participation. QoL outcomes were compared with the general population and between participants with a positive and negative screening for IA. Predictors of QoL outcomes were assessed with linear mixed effects models.

RESULTS

105 participants from 75 families were included; in 10 (10%), an IA was found. During the first year after screening, we found no negative effect on QoL, except for a temporary decrease in QoL 6 months after screening in participants with a positive screen (EQ-5D -11.3 [95% CI: -21.7 to -0.8]). Factors associated with worse QoL were psychiatric disease (EQ-5D -10.3 [95% CI: -15.1 to -5.6]), physical complaints affecting mood (EQ-5D -8.1 [95% CI: -11.7 to -4.4]), and a passive coping style (EQ-5D decrease per point increase on the Utrecht Coping List -1.1 [95% CI: -1.5 to -0.6]).

DISCUSSION AND CONCLUSION

We did not find a lasting negative effect on QoL during the first year after screening for familial IA. Predictors for a worse QoL were psychiatric disease, physical complaints affecting mood, and a passive coping style. This information can be used in counselling about familial IA screening.

Aneurysm Prevalence and Quality of Life During Screening in Relatives of Patients With Unruptured Intracranial Aneurysms: A Prospective Study

BACKGROUND AND OBJECTIVES

Screening for unruptured intracranial aneurysms (UIAs) is effective for first-degree relatives (FDRs) of patients with aneurysmal subarachnoid hemorrhage (aSAH). Whether screening is also effective for FDRs of patients with UIA is unknown. We determined the yield of screening in such FDRs, assessed rupture risk and treatment decisions of aneurysms that were found, identified potential high-risk subgroups, and studied the effects of screening on quality of life (QoL).

METHODS

In this prospective cohort study, we included FDRs, aged 20-70 years, of patients with UIA without a family history of aSAH who visited the Neurology outpatient clinic in 1 of 3 participating tertiary referral centers in the Netherlands. FDRs were screened for UIA with magnetic resonance angiography between 2017 and 2021. We determined UIA prevalence and developed a prediction model for UIA risk at screening using multivariable logistic regression. QoL was evaluated with questionnaires 6 times during the first year after screening and assessed with a linear mixed-effects model.

RESULTS

We detected 24 UIAs in 23 of 461 screened FDRs, resulting in a 5.0% prevalence (95% CI 3.2-7.4). The median aneurysm size was 3 mm (interquartile range [IQR] 2-4 mm), and the median 5-year rupture risk assessed with the PHASES score was 0.7% (IQR 0.4%-0.9%). All UIAs received follow-up imaging, and none were treated preventively. After a median follow-up of 24 months (IQR 13-38 months), no UIA had changed. Predicted UIA risk at screening ranged between 2.3% and 14.7% with the highest risk in FDRs who smoke and have excessive alcohol consumption (c-statistic: 0.76; 95% CI 0.65-0.88). At all survey moments, health-related QoL and emotional functioning were comparable with those in a reference group from the general population. One FDR with a positive screening result expressed regret about screening.

DISCUSSION

Based on the current data, we do not advise screening FDRs of patients with UIA because all identified UIAs had a low rupture risk. We observed no negative effect of screening on QoL. A longer follow-up should determine the risk of aneurysm growth requiring preventive treatment.
