Preoperative anxiety predicted the incidence of postoperative delirium in patients undergoing total hip arthroplasty: a prospective cohort study

Total shoulder arthroplasty in patients with dementia or mild cognitive impairment

Background

Anatomic total shoulder arthroplasty (ATSA) and reverse total shoulder arthroplasty (RTSA) reliably alleviate pain and restore shoulder function for a variety of indications. However, these procedures are not well-studied in patients with neurocognitive impairment. Therefore, the purpose of this study was to investigate whether patients with dementia or mild cognitive impairment (MCI) have increased odds of surgical or medical complications following arthroplasty.

Methods

The PearlDiver database was queried from 2010 through October 2021 to identify a cohort of patients who underwent either ATSA or RTSA and had a minimum 2-year follow-up. Current Procedural Terminology and International Classification of Diseases codes were used to stratify this cohort into three groups: (1) patients with dementia, (2) patients with MCI, and (3) patients with neither condition. Surgical and medical complication rates were compared among these three groups.

Results

The overall prevalence of neurocognitive impairment among patients undergoing total shoulder arthroplasty was 3.0% in a cohort of 92,022 patients. Patients with dementia had increased odds of sustaining a periprosthetic humerus fracture (odds ratio [OR] = 1.46, P < .001), developing prosthesis instability (OR = 1.72, P < .001), and undergoing revision arthroplasty (OR = 1.55, P = .003) after RTSA compared to patients with normal cognition. ATSA patients with dementia did not have an elevated risk of surgical complications or revision. Conversely, RTSA patients with MCI did not have an elevated risk of complications or revision, although ATSA patients with MCI had greater odds of prosthesis instability (OR = 2.51, P = .008). Additionally, patients with neurocognitive impairment had elevated odds of medical complications compared to patients with normal cognition, including acute myocardial infarction and cerebrovascular accident.

Conclusion

Compared to patients with normal cognition, RTSA patients with preoperative dementia and ATSA patients with preoperative MCI are at increased risk for surgical complications. Moreover, both ATSA and RTSA patients with either preoperative MCI or dementia are at increased risk for medical complications. As the mean age in the U.S. continues to rise, special attention should be directed towards patients with neurocognitive impairment to minimize postoperative complications aftertotal shoulder arthroplasty, and the risks of this surgery more carefully discussed with patients and their families and caretakers.

Cigarette smoking is linked to an increased risk of delirium following arthroplasty in patients suffering from osteoarthritic pain

AIMS

Postoperative delirium (POD) is a common postoperative complication, and the potential relationship between cigarette smoking and POD is still unclear. The current study evaluated the relationship between preoperative smoking status in patients suffering from osteoarthritic pain and POD after total knee arthroplasty (TKA).

METHODS

A total of 254 patients who had undergone unilateral TKA were enrolled between November 2021 and December 2022, with no gender limitation. Preoperatively, patients' visual analog scale (VAS) scores at rest and during movement, hospital anxiety and depression (HAD) scores, pain catastrophizing scale (PCS) scores and smoking status were collected. The primary outcome was the incidence of POD, which was evaluated by the confusion assessment method (CAM).

RESULTS

A total of 188 patients had complete datasets for final analysis. POD was diagnosed in 41 of 188 patients (21.8%) who had complete data for analysis. The incidence of smoking was significantly higher in Group POD than in Group Non-POD (22 of 41 patients [54%] vs. 47 of 147 patients [32%], p < 0.05). The postoperative hospital stays were also longer than those of Group Non-POD (p < 0.001). Multiple logistic regression analysis showed that preoperative smoking (OR: 4.018, 95% CI: 1.158-13.947, p = 0.028) was a risk factor for the occurrence of POD in patients with TKA. The length of hospital stay was correlated with the occurrence of POD.

CONCLUSIONS

Our findings suggest that patients who smoked preoperatively were at increased risk of developing POD following TKA.

The relationship between uncertainty and acute procedure anxiety among surgical patients in Chinese mainland: the mediating role of resilience

BACKGROUND

Surgery, as one of the main diagnostic and treatment methods, is a routine work in medical settings. Patients undergoing surgery often experience acute procedure anxiety due to uncertainty. There is ample evidence showing that uncertainty is a risk factor for the acute procedure anxiety in surgical patients. However, little is known about the psychological processes mediating this relationship. Therefore, this study aims to evaluate resilience as a mediator of the association between uncertainty and anxiety.

METHODS

A population-based cross-sectional survey with a convenience sampling method was conducted, involving 243 surgical patients in Jiaxing, Zhejiang province of China was carried out. Relevant data were collected by self-reporting questionnaires, including demographic characteristics questionnaire, Amsterdam Preoperative Anxiety and Information Scale (APAIS-C), Mishel's Illness Uncertainty Scale (MUIS), Connor-Davidson Resilience Scale (CD-RISC). Pearson correlation analysis was employed to examine correlations between various variables. A path model was used to assess the mediation effect of resilience with respect to uncertainty and acute procedure anxiety.

RESULTS

In the path model, uncertainty have an indirect effect on acute procedure anxiety through resilience. The results suggest that resilience has a mediating role in uncertainty and acute procedure anxiety among surgical patients.

CONCLUSIONS

These findings call for the development of interventions targeting the role of resilience in effectively predicting and preventing acute procedure anxiety and uncertainty among surgical patients.

Factors influencing the preoperative anxiety in lung cancer patients undergoing video-assisted thoracoscopic surgery: The role of information needs, illness perception and patient trust

OBJECTIVES

This study aimed to investigate preoperative anxiety in patients with lung cancer scheduled for video-assisted thoracoscopic surgery (VATS) and explore the influence of demographic factors, information needs, illness perception, and patient trust in preoperative anxiety.

METHODS

This cross-sectional study was conducted at a tertiary referral center in China from August 14 to December 1, 2022. Patients with lung cancer (N = 308) scheduled for VATS were evaluated using the Amsterdam Anxiety and Information Scale (APAIS), Brief Illness Perception Questionnaire (BIPQ), and Wake Forest Physician Trust Scale (WFPTS). Multivariate linear regression was employed to determine the independent predictors of preoperative anxiety.

RESULTS

The average total APAIS anxiety score was (10.6 ± 4.2). Of the sample, 48.4% reported high preoperative anxiety (APAIS-A: ≥10). Multivariate linear regression analysis showed that preoperative anxiety was higher in women (B = 0.860); and that preoperative length of stay ≥24 h (B = 0.016), more information needs (B = 0.988), more severe illness perceptions (B = 0.101) and more patient trust (B = -0.078) may lead to higher preoperative anxiety levels.

CONCLUSIONS

Preoperative anxiety is common in patients with lung cancer scheduled for VATS. Therefore, more attention should be paid to women and patients with a preoperative length of stay of ≥24 h. Meeting information needs, transforming positive disease perceptions, and strengthening the doctor-patient trusting relationship are key protective factors for preoperative anxiety.

Correlation and influencing factors of preoperative anxiety, postoperative pain, and delirium in elderly patients undergoing gastrointestinal cancer surgery

BACKGROUND

The correlation and influencing factors of preoperative anxiety, postoperative pain, and delirium in elderly patients undergoing gastrointestinal cancer surgery were explored with the Beck Anxiety Inventory (BAI) scale, 10-point Visual Analogue Scale (VAS), and Confusion Assessment Method Chinese Reversion (CAM-CR) scale.

METHODS

A total of 120 patients aged 65 years old who receiving gastrointestinal cancer surgery were enrolled in the study. Perioperative anxiety, pain, and delirium were assessed by the BAI scale, VAS scale, and CAM-CR scale, respectively. The correlation and influencing factors of preoperative high anxiety, postoperative high pain, and postoperative delirium were analyzed.

RESULTS

Preoperative high anxiety had a moderate positive correlation with postoperative high pain (P < 0.001, r = 0.410), and had a weak positive correlation with postoperative delirium (P = 0.005, r = 0.281). postoperative high pain had a weak positive correlation with postoperative delirium (P = 0.017, r = 0.236). Type of cancer and surgical approach were considered to be independent risk factors of preoperative high anxiety (P = 0.006 and P = 0.021). Preoperative high anxiety was considered to be an independent risk factor of postoperative high pain (P< 0.001). Age and preoperative high anxiety were considered to be independent risk factors of postoperative delirium (P< 0.001 and P = 0.010).

CONCLUSIONS

Elderly patients undergoing gastrointestinal cancer surgery had a higher incidence of preoperative anxiety, as well as first-day postoperative pain and first-day postoperative delirium. Factors such as type of cancer, surgical approach and preoperative anxiety had been identified as influencing preoperative anxiety levels; preoperative anxiety had been linked to postoperative pain; and age and preoperative anxiety have been identified as influencing factors of postoperative delirium.

Predisposing and Precipitating Factors Associated With Delirium: A Systematic Review

IMPORTANCE

Despite discrete etiologies leading to delirium, it is treated as a common end point in hospital and in clinical trials, and delirium research may be hampered by the attempt to treat all instances of delirium similarly, leaving delirium management as an unmet need. An individualized approach based on unique patterns of delirium pathophysiology, as reflected in predisposing factors and precipitants, may be necessary, but there exists no accepted method of grouping delirium into distinct etiologic subgroups.

OBJECTIVE

To conduct a systematic review to identify potential predisposing and precipitating factors associated with delirium in adult patients agnostic to setting.

EVIDENCE REVIEW

A literature search was performed of PubMed, Embase, Web of Science, and PsycINFO from database inception to December 2021 using search Medical Subject Headings (MeSH) terms consciousness disorders, confusion, causality, and disease susceptibility, with constraints of cohort or case-control studies. Two reviewers selected studies that met the following criteria for inclusion: published in English, prospective cohort or case-control study, at least 50 participants, delirium assessment in person by a physician or trained research personnel using a reference standard, and results including a multivariable model to identify independent factors associated with delirium.

FINDINGS

A total of 315 studies were included with a mean (SD) Newcastle-Ottawa Scale score of 8.3 (0.8) out of 9. Across 101 144 patients (50 006 [50.0%] male and 49 766 [49.1%] female patients) represented (24 015 with delirium), studies reported 33 predisposing and 112 precipitating factors associated with delirium. There was a diversity of factors associated with delirium, with substantial physiological heterogeneity.

CONCLUSIONS AND RELEVANCE

In this systematic review, a comprehensive list of potential predisposing and precipitating factors associated with delirium was found across all clinical settings. These findings may be used to inform more precise study of delirium's heterogeneous pathophysiology and treatment.

Psychotherapy: A tool to prevent postoperative delirium?

The value of psychotherapy in surgical patients suffering from postoperative delirium is unclear. Options for the treatment of established postoperative delirium are few; therapy largely relies on the avoidance of postoperative delirium facilitating factors, like specific drugs and environmental factors in the perioperative setting. Established medical therapies' efficacy in terms of decreasing incidence of postoperative delirium is very low. The aim of this project is to suggest new therapeutic options in the form of cognitive behavioural therapy as a possible preventive and psychotherapeutic treatment of postoperative delirium. Life expectancy in developed countries increases worldwide and both the need for surgical treatment and the probability of postoperative delirium occurrence increase with age. Due to the necessity of addressing the individual's negative consequences of postoperative delirium and to optimise socioeconomical needs, new therapeutic options for the treatment of postoperative delirium are desperately needed.

Preoperative anxiety as an independent predictor of postoperative delirium in older patients undergoing elective surgery for lumbar disc herniation

BACKGROUND

Anxiety is common in older patients suffering from lumbar disc herniation. Postoperative delirium is related to poor prognosis. But the relationship between preoperative anxiety and postoperative delirium among older patients undergoing elective surgery for lumbar disc herniation is not clear.

AIMS

The study aimed to investigate if preoperative anxiety is an independent risk factor of postoperative delirium among older patients undergoing elective surgery for lumbar disc herniation.

METHODS

The medical records of 1290 patients undergoing elective surgery for lumbar disc herniation at a single institution from 2016 through 2021 were reviewed. Of 863 eligible patients, 225 (26.1%) patients had been diagnosed with anxiety by a board-certified psychiatrist and constituted the Anxiety group; the remaining 638 patients constituted the no-anxiety group. The demographics, baseline, operative variable and postoperative complications were collected and compared between the two groups. The primary outcome of this study was the incidence of delirium, according to the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition, during a hospital stay after surgery for lumbar disc herniation. The relationship between anxiety and postoperative delirium was determined through multivariate logistic regression analysis.

RESULTS

The demographics and comorbidity were similar between the two groups, except for age, sex, alcohol use and cerebrovascular disease. The operative variables were different between the two groups. The incidence of postoperative complications other than postoperative delirium was also similar between the two groups. In total, 86 patients (9.97%) had an episode of postoperative delirium, with anxiety group patients experiencing approximately a twofold higher rate (15.6% vs 7.99%). In a multivariate logistic regression analysis, anxiety was an independent predictor of postoperative delirium in older patients undergoing elective surgery for lumbar disc herniation (OR 2.228, 95% CI 1.494-3.416, p = 0.009).

CONCLUSION

This study suggests that anxiety is an independent risk factor of postoperative delirium among older patients undergoing elective surgery for lumbar disc herniation. Preoperative anxiety assessment can help to identify older patients at high risk of postoperative delirium and facilitate perioperative management of older patients undergoing elective surgery for lumbar disc herniation.

Preoperative anxiety

PURPOSE OF REVIEW

With first research reports dating back to the 1970s, the important role of anxiety in the perioperative period has been recognized for a long time and remains in effect.

RECENT FINDINGS

The global pooled prevalence of preoperative anxiety among 14 000 surgical patients was reported to be 48%. The underlying fears among surgical patients include: fear of surgical complications, worry about the duration and degree of disability after the procedure, concerns about general anesthesia and the associated loss of control, as well as fear of waking up and experiencing discomfort and pain during or after surgery. The type and invasiveness of the planned procedure contribute to differences in preoperative anxiety levels. While preoperative anxiety is higher in younger, female patients as well as in those with a high need for information, prior exposure to anesthesia or surgery was associated with lower anxiety levels. High levels of preoperative anxiety may lead to poor postoperative pain control and increased morbidity. Due to adverse effects such as delirium, the use of benzodiazepines to manage preoperative anxiety has decreased.

SUMMARY

Preoperative anxiety remains a critical issue in the perioperative period. Further research is needed to develop effective management strategies, which may need to be tailored to the patient's individual need.

Delirium in elderly postoperative patients: A prospective cohort study

AIM

To describe the incidence, time in days and risk factors for postoperative delirium in elderly patients.

DESIGN

Prospective cohort study.

METHODS

Patients over 65 years were daily screened with the 4A's Test and the Delirium Observation Screening Scale for postoperative delirium. A psychiatrist assessed according to the DSM-V. We performed descriptive and logistic regression analyses.

RESULTS

From 202 patients, 7.5% (N = 15) had a diagnosed postoperative delirium, whereby 73.3% (N = 11) developed the delirium during the first 48 hr after surgery. The median duration was 1 day. Patients over 80 years suffering from heart failure with surgical drains, bladder catheter, central venous catheter had higher odds for developing a postoperative delirium. The incidence of postoperative delirium in our sample was lower compared with other surgical and ortho-geriatric populations. Despite age, several modifiable postoperative factors were associated with the occurrence of postoperative delirium.

Anxiety as a Risk Factor for Postoperative Delirium in Elective Spine Deformity Surgeries: A National Database Study

Introduction Generalized anxiety disorder has become one of the most prevalent mental health disorders in the United States. In addition, postoperative delirium has been shown to increase hospital stay, increase mortality, and increased healthcare costs. Few studies have looked at the prevalence of postoperative delirium in patients diagnosed with anxiety undergoing elective spinal deformity procedures. The purpose of this study was to determine if anxiety is a risk factor for postoperative delirium in elective spinal deformity surgeries. Methods The authors performed a retrospective analysis using the TriNetX Research Database. Patients diagnosed with kyphosis or lordosis who then underwent elective spinal correction surgeries were identified. This group was then separated based on the diagnosis of a generalized anxiety disorder before the operation versus no diagnosis. Propensity score adjustment, based on mental disorders and other risk factors, was then used to match cohorts on baseline demographics and characteristics. Analysis was performed on the primary outcome of postoperative delirium, with secondary outcomes of upper respiratory tract infections, surgical site infections, sepsis, ventilator dependence, convulsions, stroke, emergency department visits, myocardial infarction, pulmonary embolism, and urinary retention within 30 days after surgery. Results Our search included 1,211 patients with a diagnosis of anxiety and 8,055 patients without anxiety. After propensity score matching, 996 patients remained in each cohort. Statistical analysis showed significant outcomes between the matched cohorts in the anxiety group for postoperative delirium (OR 2.788; 1.587-4.899) and convulsions (OR 1.615; 1.006-2.592). All other outcomes were not significant after propensity score matching. Conclusion These results showed generalized anxiety disorder is a risk factor for postoperative delirium and convulsions after elective spine surgery. Further research is necessary on the effects of mental health disorders on postoperative delirium and other outcomes to better understand the risks in this population.

Preoperative Anxiety is Associated With Postoperative Complications in Vascular Surgery: A Cross-Sectional Study

BACKGROUND

Preoperative anxiety is associated with increased morbidity and/or mortality in surgical patients. This study investigated the incidence, predictors, and association of preoperative anxiety with postoperative complications in vascular surgery.

METHODS

Consecutive patients undergoing aortic, carotid, and peripheral artery surgery, under general and regional anesthesia, from February until October 2019 were included in a cross-sectional study. Anesthesiologists assessed preoperative anxiety using a validated Serbian version of the Amsterdam Preoperative Anxiety and Information Scale. Patients were divided into groups with low/high anxiety, both anesthesia- and surgery-related. Statistical analysis included multivariate linear logistic regression and point-biserial correlation.

RESULTS

Of 402 patients interviewed, 16 were excluded and one patient refused to participate (response rate 99.7%). Out of 385 patients included (age range 39-86 years), 62.3% had previous surgery. High-level anesthesia- and surgery-related anxieties were present in 31.2 and 43.4% of patients, respectively. Independent predictors of high-level anesthesia-related anxiety were having no children (OR = 0.443, 95% CI: 0.239-0.821, p = 0.01), personal bad experiences with anesthesia (OR = 2.294, 95% CI: 1.043-5.045, p = 0.039), and time since diagnosis for ≥ 4 months (OR = 1.634, 95% CI: 1.023-5.983, p = 0.04). The female sex independently predicted high-level surgery-related preoperative anxiety (OR = 2.387, 95% CI: 1.432-3.979, p = 0.001). High-level anesthesia-related anxiety correlated with postoperative mental disorders (r_pb = 0.193, p = 0.001) and pulmonary complications (r_pb = 0.104, p = 0.042). Postoperative nausea (r_pb = 0.111, p = 0.03) and postoperative mental disorders (r_pb = 0.160, p = 0.002) correlated with high-level surgery-related preoperative anxiety.

CONCLUSIONS

Since preoperative anxiety affects the postoperative course and almost every third patient experiences anxiety preoperatively, routine screening might be recommended in vascular surgery.

Post-Operative Cognitive Impairment: A Cognitive Epidemiology Perspective

Cognitive epidemiology investigates cognitive predictors of health and disease outcomes. Post-operative cognitive impairment is a common complication of surgery but has been neglected as a health outcome in cognitive epidemiology research. This is despite the fact that knowledge of cognitive predictors of post-operative cognitive impairment can be utilized for risk stratification, informed decision-making (in elective surgery), and personalized care of patients during the postoperative period. In this narrative review, the current literature on cognitive predictors of post-operative cognitive impairment and gaps therein are summarized.

Preoperative Anxiety in Chinese Adult Patients Undergoing Elective Surgeries: A Multicenter Cross-Sectional Study

BACKGROUND

Preoperative anxiety is associated with increased use of anesthetics and poorer postoperative outcomes. However, the prevalence of preoperative anxiety has not been characterized in Chinese patients. In this study, we aimed to estimate the overall prevalence of preoperative anxiety in Chinese adult patients and to explore the sociodemographic and clinical factors associated with preoperative anxiety in China.

METHODS

This study was a multicenter cross-sectional study conducted at 32 tertiary referral centers in China from September 1 to October 31, 2020. Adult patients scheduled for elective surgery were evaluated by the 7-item Perioperative Anxiety Scale (PAS-7) for preoperative anxiety after entrance to the operating zone.

RESULTS

A total of 5191 patients were recruited, and 5018 of them were analyzed. The prevalence of preoperative anxiety measured by PAS-7 was 15.8% (95% CI 14.8 to 16.9%). Multivariable analyses showed female sex, younger age, non-retired, first in a lifetime surgery, surgery of higher risk, and poorer preoperative sleep were associated with higher prevalence of preoperative anxiety.

CONCLUSIONS

Preoperative anxiety was relatively common (prevalence of 15.8%) among adult Chinese patients undergoing elective surgeries. Further studies are needed using suitable assessment tools to better characterize preoperative anxiety, and additional focus should be placed on perioperative education and intervention, especially in primary hospitals.

Influence of Anxiety/Depression, Age, Gender and ASA on 1-Year Follow-Up Outcomes Following Total Hip and Knee Arthroplasty in 5447 Patients

Introduction: There are many factors influencing the outcome after total joint arthroplasty (TJA). In particular, patient-related factors such as age, gender, ASA (American Society of Anesthesiologists), or preoperative anxiety/depression have become increasingly important. The aim of this study was to examine the association of these parameters with 1-year postoperative outcomes after total knee and total hip arthroplasty (TKA, THA). Methods: A retrospective cohort of 5447 TJA patients was evaluated by pre- and postoperative analysis of EQ-5D, EQ-VAS and WOMAC Score. Furthermore, major focus was put on the association between age, gender, ASA, preoperative anxiety/depression and outcome parameters. Results: 53.3% (2903/5447) of all patients were identified with anxiety/depression at time of surgery. In the analysis, patients without anxiety/depression showed statistically significantly (p < 0.05) better EQ-5D, EQ-VAS and WOMAC scores. In addition, patients with ASA 2 or 3 and age over 70 years showed statistically significantly (p < 0.01) worse EQ-5D and WOMAC scores. Gender did not influence the postoperative EQ-5D and WOMAC results, but men had significantly better EQ-VAS scores than women in this study. Conclusion: Preoperative anxiety/depression symptoms show worse clinical outcomes 1 year postoperatively after TJA. Other outcome-influencing factors are higher age and ASA 2 or 3. In the future, such patients should be identified, and as far as applicable, a treatment of anxiety/depression or comorbidities should be implemented preoperatively of the surgical procedure to improve clinical outcomes.
