Review
AIMS AND OBJECTIVES
Evidence suggests that preparing patients for surgery using nonpharmacological strategies reduces their anxiety. However, there is no consensus on what the best practices are. This study aims to answer the question: Are interventions using nonpharmacological therapies effective in reducing preoperative anxiety?
BACKGROUND
Preoperative anxiety causes physiological and psychological adverse effects, with a negative effect on postoperative recovery.
INTRODUCTION
According to the World Health Organization, between 266 and 360 million surgical procedures are performed annually worldwide, and it is estimated that more than 50% of patients will experience some degree of preoperative anxiety.
DESIGN
Systematic review of systematic reviews with results of interventions aimed at mitigating preoperative anxiety.
METHODS
A search was conducted for systematic reviews with meta-analyses published between 2012 and 2021 in Medline, Scopus, Web of Science and Cochrane Library. Quality was assessed using the AMSTAR-2 scale. The protocol was registered in PROSPERO.
RESULTS
A total of 1016 studies were examined, of which 17 systematic reviews were selected, yielding 188 controlled trials with 16,884 participants. In adults, the most common intervention included music, followed by massage, in children virtual reality and clowns. Almost all controlled trials reported a reduction in preoperative anxiety after the intervention, of which almost half had statistically significant results.
CONCLUSION
Interventions that include music, massage and virtual reality reduce preoperative anxiety and have shown that they are cost-effective, minimally invasive and with a low risk of adverse effects. Preoperative anxiety can be reduced through a short-term intervention involving nursing professionals as an alternative or complement to drugs.
RELEVANCE TO CLINICAL PRACTICE
This review suggests that nursing professionals, in collaboration with other health professionals, should continue to conduct research on the reduction in preoperative anxiety. Further research in this area is needed, to reduce heterogeneity and consolidate the results.

Meta-Analysis
BACKGROUND
Both frailty and postoperative delirium (POD) are common in elective surgical patients 65 years of age and older. However, the association between preoperative frailty and POD remains difficult to characterize owing to the large number of frailty and POD assessment tools used in the literature, only a few of which are validated. Furthermore, some validated frailty tools fail to provide clear score cutoffs for distinguishing frail and nonfrail patients. We performed a meta-analysis to estimate the relationship between preoperative frailty and POD.
METHODS
We searched several major databases for articles that investigated the relationship between preoperative frailty and POD in patients with mean age ≥65 years who were undergoing elective, nonemergent inpatient surgery. Inclusion criteria included articles published in English no earlier than 1999. Both preoperative frailty and POD must have been measured with validated tools using clear cutoff scores for frailty and delirium. Articles were selected and data extracted independently by 2 researchers. Risk of bias (ROBINS-I) and presence of confounders were summarized. Odds ratios (ORs) for POD associated with frailty relative to nonfrailty were computed with adjusted ORs when available. Original estimates were pooled by random effects analysis. Statistical significance was set at 2-sided P < .05.
RESULTS
Nine studies qualified for meta-analysis. The Fried score or a modified version of it was used in 5 studies. Frailty prevalence ranged from 18.6% to 56%. Delirium was assessed with the Confusion Assessment Method (CAM) or Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) in 7 studies, Delirium Observation Scale in 1 study, and Intensive Care Delirium Screening Checklist in 1 study. The incidence of POD ranged from 7% to 56%. ROBINS-I risk of bias was low in 1 study, moderate in 4 studies, serious in 3 studies, and critical in 1 study. Random effects analysis (n = 794) of the OR for POD in frail versus nonfrail patients based on adjusted OR estimates was significant with an OR of 2.14 and a 95% confidence interval of 1.43-3.19. The I2 value was in the low range at 5.5, suggesting small variability from random effects. Funnel-plot analysis did not definitively support either the presence or absence of publication bias.
CONCLUSIONS
This meta-analysis provides evidence for a significant association between preoperative frailty and POD in elective surgical patients age 65 years or older.

Meta-Analysis Review
Determining the prevalence and risk factors related to sleep disturbance in surgical patients would be beneficial for risk stratification and perioperative care planning. The objectives of this systematic review and meta-analysis are to determine the prevalence and risk factors of sleep disturbances and their associated postoperative complications in surgical patients. The inclusion criteria were: (1) patients ≥18 years old undergoing a surgical procedure, (2) in-patient population, and (3) report of sleep disturbances using a validated sleep assessment tool. The systematic search resulted in 21,951 articles. Twelve patient cohorts involving 1497 patients were included. The pooled prevalence of sleep disturbances at preoperative assessment was 60% (95% Confidence Interval (CI): 50%, 69%) and the risk factors for postoperative sleep disturbances were a high preoperative Pittsburgh sleep quality index (PSQI) score indicating preexisting disturbed sleep and anxiety. Notably, patients with postoperative delirium had a higher prevalence of pre- and postoperative sleep disturbances and high preoperative wake after sleep onset percentage (WASO%). The high prevalence of preoperative sleep disturbances in surgical patients has a negative impact on postoperative outcomes and well-being. Further work in this area is warranted.

Review
PROBLEM
The role of play in the reduction of anxiety and pain and in the improvement of behaviours and overall wellbeing in children in the field of nursing care in hospital settings.
ELIGIBILITY CRITERIA
Studies published during the period 2014-2019 including original articles in English, Spanish and Portuguese. Databases consulted: SCOPUS, MEDLINE/PubMed, WoS, and CUIDEN (Nursing database in Spanish).
SAMPLE
Seventeen relevant records were selected. After critical reading using the CASPe (Critical Appraisal Skills Programme in Spanish) instrument, 7 articles were rejected and 10 were finally selected.
RESULTS
Each of eight studies showed significant evidence for the role of therapeutic play in the reduction of anxiety and pain and in the overall wellbeing of paediatric patients.
IMPLICATIONS
This review aimed to critically assess and synthesize the existing empirical evidence on the contributions of therapeutic play interventions for reducing anxiety, pain and improving the overall wellbeing of paediatric patients.
CONCLUSIONS
Based on these findings, it may be safe to say that therapeutic play interventions are effective in reducing the negative emotional manifestations of children, decreasing preoperative anxiety and pain, improving compliance with the induction of anaesthesia and reducing anxiety and postoperative pain. There is also evidence that dramatic puppetry is an effective preoperative care and preparation strategy for reducing anxiety in children undergoing surgery.

Meta-Analysis
INTRODUCTION
Preoperative anxiety and postoperative pain are common problems in patients undergoing surgery. The aim of this study is to analyse the effect of using guided imagery prior to surgery in adults and children to reduce preoperative anxiety and acute postoperative pain, compared with conventional preoperative nursing care.
METHODS
A systematic review and meta-analysis were conducted. We searched randomised clinical trials in databases and search engines.
RESULTS
A total of 1101 records were identified, of which 21 were included in the qualitative synthesis. Two random model meta-analysis were performed with eight trials. Guided imagery preoperatively was shown to be effective in relieving preoperative state anxiety in children (d = -3.71), preoperative trait anxiety in adults (d = -0.64) and postoperative pain in adults (d = -0.24). Postoperative pain in children and preoperative state anxiety in adults was reduced but without significant difference.
CONCLUSION
Guided imagery preoperatively is an effective, easy and low-cost intervention.

Meta-Analysis Review
BACKGROUND
Preoperative anxiety is prevalent amongst adults with elective surgery and is associated with multiple detrimental perioperative physiological effects. Increasing studies support the effectiveness of acupressure in managing preoperative anxiety. However, the magnitude of acupressure's positive association with preoperative anxiety is still unclear due to a lack of rigorous evidence synthesis.
OBJECTIVE
To estimate the efficacy of acupressure on preoperative anxiety and physiological parameters amongst adults scheduled for elective surgery.
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
Search terms were combined for acupressure and preoperative anxiety in PubMed, Cochrane Library, EMBASE, CINAHL, China National Knowledge Infrastructure, and WanFang Data Knowledge Service Platform to search for eligible randomised controlled trials from the inception of each database through September 2022.
METHODS
Pairs of researchers independently screened and extracted data from included studies. The risk of bias was assessed using the Cochrane risk of bias tool Version 2.0. Meanwhile, random-effects meta-analysis of overall effects and prespecified subgroup (i.e., surgery types, intervention providers, and acupressure stimulation tools) was conducted using Review Manager Software 5.4.1. Meta-regression was performed to explore study-level variables that may contribute to heterogeneity using STATA 16.
RESULTS
Of 24 eligible randomised controlled trials, there were a total of 2537 participants from 5 countries contributed to this synthesis. When comparing acupressure with usual care or placebo, acupressure showed a large effect size for preoperative anxiety (SMD = -1.30; 95%CI = -1.54 to -1.06; p < 0.001; I = 86%). The significant mean reduction of heart rate, and systolic and diastolic blood pressure was -4.58 BPM (95%CI = -6.70 to -2.46; I = 89%), -6.05 mmHg (95%CI = -8.73 to -3.37; p < 0.001; I = 88%), and -3.18 mmHg (95%CI = -5.09 to -1.27; p = 0.001; I = 78%), respectively. Exploratory subgroup analyses showed significant differences in surgery types and acupressure stimulation tools, whilst the intervention providers (i.e., healthcare professionals and self-administered) showed no statistically significant difference for acupressure therapy. None of the predefined participants and study-level characteristics moderated preoperative anxiety through meta-regression.
CONCLUSION
Acupressure appears efficacious as a therapy for improving preoperative anxiety and physiological parameters amongst adults with elective surgery. Self-administered acupressure, which is effective with a large effect, may be considered as an evidence-based approach to managing preoperative anxiety. Hence, this review aids in the development of acupressure in different types of elective surgeries and the improvement of the rigour of acupressure therapy.

Comparative Study Meta-Analysis
The Comparative Efficacy of Chlorhexidine Gluconate and Povidone-iodine Antiseptics for the Prevention of Infection in Clean Surgery: A Systematic Review and Network Meta-analysis.
OBJECTIVE
There is uncertainty around preoperative skin antisepsis in clean surgery. Network meta-analysis provides more precise estimates than standard pairwise meta-analysis and can rank interventions by efficacy, to better inform clinical decisions.
BACKGROUND
Infection is the most common and costly complication of surgery. The relative efficacy of CHG and PVI based skin antiseptics in clean surgery remains unclear.
METHODS
We searched for randomized or nonrandomized studies comparing the effect of different preparations of CHG and PVI on the dichotomous outcome of surgical site infection. We included studies of adults undergoing clean surgery. We excluded studies concerning indwelling vascular catheters, blood sampling, combination antiseptics or sequential applications of different antiseptics. We performed a network meta-analysis to estimate the relative efficacy of interventions using relative risks (RR).
RESULTS
We included 17 studies comparing 5 antiseptics in 14,593 individuals. The overall rate of surgical site infection was 3%. Alcoholic CHG 4%-5% was ranked as the most effective antiseptic as it halved the risk of surgical site infection when compared to aqueous PVI [RR 0.49 (95% confidence interval 0.24, 1.02)] and also to alcoholic PVI, although uncertainty was larger [RR 0.51 (95% confidence interval 0.21, 1.27)]. Adverse events related to antiseptic application were only observed with patients exposed to PVI.
CONCLUSIONS
Alcoholic formulations of 4%-5% CHG seem to be safe and twice as effective as PVI (alcoholic or aqueous solutions) in preventing infection after clean surgery in adults. Our findings concur with the literature on contaminated and clean-contaminated surgery, and endorse guidelines worldwide which advocate the use of alcoholic CHG for preoperative skin antisepsis.

Meta-Analysis Review
BACKGROUND
Preoperative anxiety is very common in adults awaiting all types of surgical procedures, which can interfere with the start and completion of surgery and increase the risk of postoperative complications. In this context, many researchers and clinical practitioners have attempted to use aromatherapy to help adults reduce preoperative anxiety.
OBJECTIVE
To investigate systematically the efficacy of aromatherapy on preoperative anxiety in adults.
DESIGN
A systematic review and meta-analysis of randomized controlled trials was undertaken.
DATA SOURCES
PubMed, Embase, Cochrane Library, Web of Science, PsycINFO and CINAHL were comprehensively searched from their inception to June 2020.
REVIEW METHODS
Studies on the use of aromatherapy for treating preoperative anxiety in adults were included. Two reviewers assessed the risk of bias of the included studies independently using the Cochrane Collaboration 'Risk of Bias' tool. Overall meta-analysis and five subgroup analyses regarding the type of control, the type of aroma preparations, delivery mode, session length and surgery type were performed using RevMan 5.3. The Higgins' I (%) statistic was used to measure heterogeneity. A funnel plot and Egger's test were used to evaluate publication bias.
RESULTS
Twenty studies comprising 1717 participants were included. The meta-analysis indicated that aromatherapy could significantly ameliorate preoperative anxiety (standard mean difference=-0.57, 95% confidence interval [-0.75, -0.39], p<0.00001) for adults awaiting surgical procedures, compared to placebo control, conventional care and no intervention. The subgroup analysis based on the surgery type showed that aromatherapy had a great improvement on preoperative anxiety for patients awaiting cardiac surgery and relatively low-risk surgery. Lavender oil, citrus species preparations and rose oil were the three most commonly used aroma preparations that could significantly improve preoperative anxiety. Most delivery modes of aromatherapy, including inhalation, massage, and oral administration, were effective. Moreover, short length (≤20 min per session) aromatherapy showed a better effect on preoperative anxiety (mean difference=-5.84, 95% confidence interval [-8.09, -3.59], p<0.00001) than aromatherapy lasting more than 20-minutes per session (mean difference=-2.15, 95% confidence interval [-3.81, -0.49], p = 0.01).
CONCLUSION
Aromatherapy is an effective intervention for reducing preoperative anxiety in adults. Short-length aromatherapy inhalation seems to be more worthy of being recommended in clinical settings. More well-designed randomized controlled trials containing a wider range of surgical types and participants from more countries are needed to verify our findings before we can make strong recommendations.

Meta-Analysis Review
PURPOSE
Functional capacity is an independent indicator of morbidity in colon and rectal cancer surgery. This systematic review describes the evaluated and synthesized effects of exercise prehabilitation depending on the duration of interventions on functional and postoperative outcomes in colon and rectal cancer surgery.
METHODS
Three electronic databases (MEDLINE Pubmed, Web of Sciences, and Cochrane Registry) were systematically searched (January 2022) for controlled trials that investigated the effects of prehabilitation prior to colo-rectal cancer resection.
RESULTS
Twenty-three studies were included in this systematic review and 14 in our meta-analyses assessing these outcomes: the 6 min walk distance (6MWD), postoperative overall complications, and length of stay (LOS). We observed a significant improvement in preoperative functional capacity as measured with 6MWD (mean difference: 30.8 m; 95% CI 13.3, 48.3; p = 0.0005) due to prehabilitation. No reductions in LOS (mean difference: - 0.27 days; 95% CI - 0.93, 0.40; p = 0.5) or postoperative overall complications (Odds ratio: 0.84; 95% CI 0.53, 1.31; p = 0.44) were observed. Prehabilitation lasting more than 3 weeks tended to lower overall complications (Odds ratio: 0.66; 95% CI 0.4, 1.1; p = 0.11). However, the prehabilitation time periods differed between colon and rectal carcinoma resections.
CONCLUSION
Prehabilitation while the patient is preparing to undergo surgery for colorectal carcinoma improves functional capacity; and might reduce postoperative overall complications, but does not shorten the LOS. The studies we reviewed differ in target variables, design, and the intervention's time period. Multicenter studies with sufficient statistical power and differentiating between colon and rectal carcinoma are needed to develop implementation strategies in the health care system.

Meta-Analysis Review
PURPOSE
To systematically review technical aspects and treatment regimens of botulinum toxin A (BTA) injections in the lateral abdominal wall musculature. We also investigated the effect of BTA on abdominal muscle- and hernia dimensions, and clinical outcome.
METHODS
PubMed, EMBASE, CENTRAL, and CINAHL were searched for studies that investigate the injection of BTA in the lateral abdominal wall muscles. Study characteristics, BTA treatment regimens, surgical procedures, and clinical outcomes are presented descriptively. The effect of BTA on muscle- and hernia dimensions is analyzed using random-effects meta-analyses, and exclusively for studies that investigate ventral incisional hernia patients.
RESULTS
We identified 23 studies, comprising 995 patients. Generally, either 500 units of Dysport or 200-300 units of Botox are injected at 3-5 locations bilaterally in all three muscles of the lateral abdominal wall, about 4 weeks prior to surgery. No major procedural complications are reported. Meta-analyses show that BTA provides significant elongation of the lateral abdominal wall of 3.2 cm per side (95% CI 2.0-4.3, I = 0%, p < 0.001); 6.3 cm total elongation, and a significant but heterogeneous decrease in transverse hernia width (95% CI 0.2-6.8, I = 94%, p = 0.04). Furthermore, meta-analysis shows that BTA pretreatment in ventral hernia patients significantly increases the fascial closure rate [RR 1.08 (95% CI 1.02-1.16, I = 0%, p = 0.02)].
CONCLUSION
The injection technique and treatment regimens of botulinum toxin A as well as patient selection require standardization. Bilateral pretreatment in hernia patients significantly elongates the lateral abdominal wall muscles, making fascial closure during surgical hernia repair more likely.
