Efficacy of serious games for chronic pain management in older adults: A systematic review and meta-analysis.

AIMS AND OBJECTIVES: To synthesise and appraise the evidence of the efficacy of serious games in reducing chronic pain among older adults. BACKGROUND: Chronic pain in older adults generally results in a substantial handicap due to decreased mobility, exercise avoidance and various concerns that affect their overall quality of life. While serious games have been widely used as a pain management approach, no reviews have thoroughly examined their efficacy for chronic pain management in older adult populations. DESIGN: A systematic review and meta-analysis. METHODS: The CINAHL, the Cochrane Library, Embase, Medline, PubMed and Web of Science databases were comprehensively searched to find articles published from their inception until 17 April 2023. RoB-2 was used to assess the risk of bias in the included studies. The efficacy of serious games for pain management in older individuals was investigated using pooled standardised mean differences (SMDs) in pain reduction using a random effect model. RESULTS: The meta-analysis comprised nine randomised controlled trials that included 350 older adult patients with pain. Serious games effectively alleviated pain in this group (pooled SMD = -0.62; 95% confidence interval: -1.15 to -0.10), although pain-related disability and fear require further investigation. CONCLUSIONS: Serious games tended to effectively reduce pain in this older adult group; however, due to a lack of randomised controlled trials, the analysis found lower effectiveness in reducing pain-related disability and fear. Further studies are accordingly required to confirm these findings. RELEVANCE TO CLINICAL PRACTICE: The findings of the study emphasise the importance of serious games to increase the motivation of older adults to exercise as one of the safe and extensively used pain management strategies. Serious games that effectively reduce chronic pain in older adults are characterised as consisting of diverse physical activities delivered through consoles, computer-based activities and other technologies. PATIENT OR PUBLIC CONTRIBUTIONS: Serious games are recommended as being potentially useful and practical for reducing pain in older adults.

Modified Vaginal Mesh Procedure with DynaMesh®-PR4 for the Treatment of Anterior/Apical Vaginal Prolapse.

(1) Background: Treating female pelvic organ prolapse (POP) is challenging. Surgical meshes have been used in transvaginal surgeries since the 1990s, but complications such as mesh exposure and infection have been reported. Polyvinylidene fluoride (PVDF) mesh, known for its stability and non-reactive properties, has shown promise in urogynecological surgeries. (2) Methods: A retrospective analysis was conducted on 27 patients who underwent a modified PVDF vaginal mesh repair procedure using DynaMesh®-PR4 and combined trans-obturator and sacrospinous fixation techniques. Additional surgeries were performed as needed. (3) Results: The mean operation time was 56.7 min, and the mean blood loss was 66.7 mL. The average hospitalization period was 4.2 days with Foley catheter removal after 2 days. Patients experienced lower pain scores from the day of the operation to the following day. Postoperative follow-up revealed that 85.2% of patients achieved anatomic success, with 14.8% experiencing recurrent stage II cystocele. No recurrence of apical prolapse was observed. Complications were rare, with one case (3.7%) of asymptomatic mesh protrusion. (4) Conclusions: The modified vaginal mesh procedure using DynaMesh®-PR4 showed favorable outcomes with a short operation time, low recurrence rate, rare complications, and improved functional outcomes. This surgical option could be considered for anterior and apical pelvic organ prolapse in women.

Parental Educational Intervention to Facilitate Informed Consent for Pediatric Procedural Sedation in the Emergency Department: A Parallel-Group Randomized Controlled Trial.

Obtaining valid parental informed consent for pediatric procedures in the emergency department (ED) is challenging. We compared a video-assisted informed consent intervention with conventional discussion to inform parents about pediatric procedural sedation in the ED. We conducted a prospective randomized controlled trial using a convenience sample including the parents of children in the ED in whom procedural sedation for facial laceration was recommended. The video group watched an informational video. Conventional group participants received information from physicians during conventional discussion. The primary outcome was knowledge improvement of the video intervention compared with conventional discussion. The secondary outcome was parental satisfaction. Video and conventional groups comprised 32 and 30 participants, respectively. Mean knowledge scores of parents after intervention [±standard deviation] were higher in the video group (91.67 ± 12.70) than in the conventional group (73.33 ± 19.86). Knowledge score differences were significantly bigger in the video group (coefficient: 18.931, 95% confidence interval: 11.146-26.716). Video group participants reported greater satisfaction than conventional group participants. Parents' comprehension of and satisfaction with the informed consent process for pediatric procedural sedation may be improved with the use of an educational video. Standardized approaches should be developed by healthcare institutions to better educate parents, facilitate treatment decisions, and boost satisfaction in the ED.

Changes in Cystoscopic Findings after Intravesical Hyaluronic Acid Instillation Therapy in Patients with Interstitial Cystitis.

(1) Background: Limited data showed changes in glomerulation in the bladder mucosa of patients with interstitial cystitis (IC) after intravesical hyaluronic acid (HA) bladder infusion. We aimed to investigate the above changes. (2) Methods: Medical records of IC patients were reviewed retrospectively, from January 2010 to October 2019. Patients who had received repeated cystoscopy after intravesical HA treatment were enrolled. The associations of multiple parameters, including the ages, symptoms, initial glomerulation stage, HA doses, and the interval period of repeated cystoscopy between the glomerulation change in the repeated cystoscopy were analyzed. (3) Results: Among the 35 patients, 9 cases (25.7%) showed better glomerulation grades in the repeated cystoscope (Group 1), 20 cases (57.1%) showed the same grades (Group 2), and 6 cases showed worse grades (Group 3). No difference was seen in the initial grades or treatment course among the three groups. The interval periods from the initial to the repeated cystoscopy of Group 1 were longer than Group 2 and Group 3 (p = 0.031). Group 3 presents an elder age trend than the other two groups. (4) Conclusion: Intravesical HA repaired bladder glomerulation in a small group of patients with IC. Prolonged treatment has potential benefits, while older age is possibly a negative factor. However, no strong correlation was found between the initial glomerulation grades or changes in glomerulation grades with clinical symptoms.

Global prevalence of stigmatization and violence against healthcare workers during the COVID-19 pandemic: a systematic review and meta-analysis.

PURPOSE: During COVID-19, stigmatization and violence against and between professional healthcare workers worldwide are increasing. Understanding the prevalence of such stigmatization and violence is needed for gaining a complete picture of this issue. Therefore, the purpose of this review was to update estimates of the prevalence of stigmatization and violence against healthcare workers during the pandemic. DESIGN: A systematic review and meta-analysis was conducted. METHODS: This review followed PRISMA guidelines and encompassed these databases: PubMed, Academic Search Complete, CINAHL, Web of Science, MEDLINE Complete, OVID (UpToDate), and Embase (from databases inception to September 15, 2021). We included observational studies and evaluated the quality of the study using the Joanna Briggs Institute methodology. Further, a random effects model was used to synthesis the pooled prevalence of stigmatization and violence in this study. FINDINGS: We identified 14 studies involving 3452 doctors, 5738 nurses, and 2744 allied health workers that reported stigmatization and violence during the pandemic. The pooled prevalence was, for stigmatization, 43% (95% confidence interval [CI]: 21% to 65%) and, for violence, 42% (95% CI: 30% to 54%). CONCLUSIONS: Stigmatization and violence during the COVID-19 pandemic were found to have affected almost half the studied healthcare workers. Healthcare professionals are more prone to be stigmatized by the community and to face workplace violence. CLINICAL RELEVANCE: Health administrators and policymakers should anticipate and promptly address stigmatization and violence against and between healthcare workers, while controlling the spread of COVID-19. Health care systems should give serious attention to the mental health of all health providers.

The moderating effect of personality traits on acute tinnitus sensation in idiopathic sudden sensorineural hearing loss.

BACKGROUND: People may experience tinnitus after sudden hearing impairment. The details of the relationship between tinnitus improvement and hearing recovery are still unclear. Personality traits may play a role in the modulation of tinnitus sensation. We investigated the moderating effect of personality traits on pretreatment and posttreatment tinnitus sensation in patients with idiopathic sudden sensorineural hearing loss (ISSHL). METHODS: This prospective longitudinal study enrolled 33 patients diagnosed with unilateral ISSHL and acute tinnitus in 2018-2019 at one institute. Clinical data were collected before and after treatment, including results of pure-tone audiometry (PTA), the Clinical Tinnitus Questionnaire (CTQ), the Tinnitus Handicap Inventory (THI), tinnitus loudness and annoyance (Visual Analog Scale; VAS), the Hospital Anxiety and Depression Scale (HADS), and the Big Five Inventory (BFI)-44. RESULTS: Eighteen men and 15 women with an average age of 48.3 ± 15.8 years were enrolled. The pretreatment hearing threshold and THI score were 58.0 ± 27.4 dB HL and 42.9 ± 26.2 (range: 0-88), respectively; the posttreatment values were 39.8 ± 22.4 dB HL and 20.7 ± 22.5 (range: 0-64), respectively. There were significant differences between pretreatment and posttreatment hearing thresholds as well as THI, VAS, and HADS scores (p < 0.001) but not BFI-44 results. Neuroticism and openness had significant positive and negative correlations, respectively, with acute tinnitus stress before treatment (r = 0.561, p = 0.001; r = -0.359, p = 0.040). After 3 months of follow-up, all patients were analyzed separately by dividing them into recovery (n = 16) and nonrecovery groups (n = 14) according to their hearing improvement status by Siegel's criteria. Neuroticism showed a significant moderating effect on acute tinnitus sensation in the ISSHL recovery group (p < 0.001) but not in the nonrecovery group (p = 0.106). CONCLUSION: Neuroticism and openness may affect acute tinnitus stress in ISSHL patients. Practitioners should consider personality traits when managing ISSHL patients with bothersome tinnitus.

Effects of resistance bands exercise for frail older adults: A systematic review and meta-analysis of randomised controlled studies.

AIMS AND OBJECTIVES: Research examining the effectiveness of resistance band exercises for improving physical and psychological dimensions among frail older adults has been inconsistent. We aimed to examine the effects of resistance band exercises for improving outcomes in frail older adults. BACKGROUND: To provide robust evidence regarding the effectiveness of resistance band exercises and explore other potential outcomes in frail older adults, a systematic review of RCTs remains necessary. DESIGN: Systematic literature review and meta-analysis were conducted in accordance with the PRISMA guidelines. METHODS: Four databases were searched. English language papers were retrieved from 2006 to 2020. Three reviewers reviewed the methodology of the selected studies using the Joanna Briggs Institute tool for randomised controlled trials. The pooled standardised mean difference was calculated using a random-effects model. Heterogeneity among pooled studies was assessed using the τ2 , Q and I2 statistics, and publication bias was evaluated using Egger's test and the visual inspection of funnel plots. RESULTS: A total of 15 studies met the eligibility criteria for this study. Overall, resistance band exercise reduced frailty after 24 weeks (SMD: -0.29; 95% CI: -0.55 to -0.03) and reduced depression after both 12 weeks (SMD: -0.19; 95% CI: -0.38 to -0.01) and 24 weeks (SMD: -0.30; 95% CI: -0.52 to -0.09). However, no significant effects were observed for frailty after 12 weeks, and no significant effects were observed for grip strength, leg strength, activities of daily living or quality of life at any time. CONCLUSION: Resistance band exercise might be considered a viable strategy for frail older adults in the community or in long-term care facilities. More research implementing a standardised protocol remains necessary to identify the effects of different training volumes and the dose-response relationship for the very old and frail population. RELEVANCE TO CLINICAL PRACTICE: As a safe complementary intervention for frail older adults, health providers should consider resistance band exercises when caring for frail older adults because this intervention has clinical benefits.

Adherence to Iron and Folic Acid Supplementation (IFAS) intake among pregnant women: A systematic review meta-analysis.

OBJECTIVE: Adherence to iron and folic acid supplementation represents a significant factor contributing to the prevention and treatment of anaemia in pregnancy. However, limited studies have systematically investigated iron and folic acid supplementation adherence among pregnant mothers using a global perspective. We aimed to systematically identify iron and folic acid supplementation adherence and associated factors among pregnant women. DESIGN: For this systematic review and meta-analysis, we did a systematic search of Academic Search Complete, CINAHL, MEDLINE, PubMed, and Web of Science from inception to October 20, 2020. We included all cohort, case-control, and cross-sectional studies and used the Joanna Briggs Institute tool to assess study quality. A meta-analysis was performed to synthesise the pooled odds ratio for iron and folic acid supplementation adherence using a random-effects model. Heterogeneity was measured using the I2 statistic, and Egger's test was used to assess publication bias. MEASUREMENTS AND FINDINGS: Eighteen studies were included in systematic review and meta-analysis, including a total of 5,537 pregnant women. The pooled odds ratio for iron and folic acid supplementation adherence in primipara vs multipara, anaemia vs non-anaemia, knowledgeable vs limited knowledge of anaemia, and knowledgeable vs limited knowledge of iron and folic acid supplementation were 3.91 (95% confidence interval: 1.75-8.75), 1.09 (95% confidence interval: 0.67-1.77), 0.32 (95% confidence interval: 0.15-0.69), and 2.48 (95% confidence interval: 1.13-5.47), respectively. KEY CONCLUSIONS: This review yielded evidence that having one pregnancy, having anaemia, and having satisfactory knowledge of both anaemia and iron and folic acid supplementation were positively associated with iron and folic acid supplementation adherence.

Effects of telehealth interventions on performing activities of daily living and maintaining balance in stroke survivors: A systematic review and meta-analysis of randomised controlled studies.

BACKGROUND: Stroke is one of the most common causes of disability worldwide. In recent years, diverse telehealth programmes for stroke survivors have suggested that this mode of rehabilitation could improve stroke survivors' abilities to perform activities of daily living (ADLs) and maintain balance. Although increasingly utilised in clinical and community settings, the effectiveness of telehealth interventions in stroke survivors remains inconclusive. This warrants investigation so that telehealth interventions are evidence-based and are not merely modalities of convenience. AIM: To identify the effects of telehealth interventions on the ability to perform ADLs and maintain balance in stroke survivors. DESIGN: A systematic literature review and meta-analysis were conducted in accordance with PRISMA guidelines. METHODS: A systematic literature search was performed using seven databases for literature dated up to April 25, 2021. The revised Cochrane risk of bias tool for randomised trials was used to assess the methodological quality of the included studies. A meta-analysis was performed using a random-effects model to calculate the pooled effects of telehealth interventions. Stata 16.0 was used for the statistical analyses. RESULTS: A total of 14 studies with 1,367 participants were included in the analysis. Overall, telehealth interventions were effective in improving stroke survivors' abilities to carry out their ADLs (standardised mean difference: .45; 95% confidence interval: .12 to .78); however, no significant effects were found on balance. CONCLUSION: Telehealth interventions are beneficial for improving stroke survivors' performance of their ADLs. Future telehealth intervention trials should focus on identifying essential intervention delivery components that facilitate intervention adoption by clinicians and stroke survivors and sustain the positive effects on stroke survivors' performance of their ADLs in different settings. RELEVANCE TO CLINICAL PRACTICE: It is essential to build flexibility in the telehealth-based intervention delivery protocol to meet individual stroke survivors' needs to motivate and enhance their ADL performance.

Global prevalence of mental health problems among healthcare workers during the Covid-19 pandemic: A systematic review and meta-analysis.

BACKGROUND: Healthcare workers are at high risk of developing mental health issues during the coronavirus disease 2019 (COVID-19) pandemic. However, there is a need for a full picture of mental health problems with comprehensive analysis among healthcare workers during the COVID-19 pandemic. OBJECTIVE: This review aimed to systematically identify the mental health problems among healthcare workers in various countries during the COVID-19 pandemic. DESIGN: Systematic review and meta-analysis. METHODS: A systematic literature search was performed of the following databases: PubMed, Academic Search Complete, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, MEDLINE Complete, and SocINDEX. The last date of our search was November 2, 2020. We included all cohort, case-control and cross-sectional studies and used the Joanna Briggs Institute tool to assess their quality. A meta-analysis was performed to synthesize the pooled prevalence of mental health problems using a random-effects model. Heterogeneity was measured using the I2 statistic and Egger's test was used to assess publication bias. RESULTS: A total of 38 studies were identified that reported the mental health problems of healthcare workers during the COVID-19 pandemic. The distribution of healthcare workers analyzed in this review included 27.9% doctors, 43.7% nurses, and 7.0% allied health workers. The pooled prevalence of mental health problems for post-traumatic stress disorder, anxiety, depression, and distress was 49% (95% confidence interval [CI]: 22-75%), 40% (95% CI: 29-52%), 37% (95% CI: 29-45%), and 37% (95% CI: 25-50%), respectively. CONCLUSION: This review yielded evidence that estimated the global prevalence of mental health problems among healthcare workers during the COVID-19 pandemic. Post-traumatic stress disorder was the most common mental health disorder reported by healthcare workers during the COVID-19 pandemic, followed by anxiety, depression, and distress. Additional studies remain necessary to assess the appropriate management strategies for treating and preventing mental health disorders among healthcare workers during the pandemic.

Frailty as a mortality predictor in older adults with COVID-19: A systematic review and meta-analysis of cohort studies.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has caused the coronavirus diseases 2019 (COVID-19) pandemic, continues to spread rapidly worldwide and is associated with high rates of mortality among older adults, those with comorbidities, and those in poor physiological states. This paper aimed to systematically identify the impact of frailty on overall mortality among older adults with COVID-19. We conducted a systematic review of the literature indexed in 4 databases. A random-effects model with inverse variance-weighted meta-analysis using the odds ratio was used to study the association of frailty levels with clinical outcomes among older adults with COVID-19. Heterogeneity was measured using the I2 statistic and Egger's test. We identified 22 studies that met our inclusion criteria, including 924,520 total patients. Overall, frailty among older adults was associated with high rates of COVID-19-related mortality compared with non-frail older adults (OR [odds ratio]:5.76; 95% confidence interval [95% CI]: 3.85-8.61, I2: 40.5%). Our results show that physical limitations, such as those associated with frailty among older adults, are associated with higher rates of COVID-19-related mortality.

Dementia as a mortality predictor among older adults with COVID-19: A systematic review and meta-analysis of observational study.

The purpose of this study was to systematically examine the association between dementia and mortality among older adults with COVID-19. To do so, we conducted a search of 7 databases for relevant full-text articles. A cohort study and case-control study were included. A meta-analysis was performed to synthesize the pooled odds ratio with a random-effects model. We identified studies that reported mortality among older adults with dementia and non-dementia who have COVID-19. The pooled mortality rates of dementia and non-dementia older adults infected with COVID-19 were 39% (95% CI: 0.23-0.54%, I2 = 83.48%) and 20% (95% CI: 0.16-0.25%, I2 = 83.48%), respectively. Overall, dementia was the main factor influencing poor health outcomes and high rates of mortality in older adults with COVID-19 infection (odds ratio 2.96; 95% CI 2.00-4.38, I2 = 29.7%), respectively. Our results show that older adults with dementia with COVID-19 infection have a higher risk of mortality compared with older adults without dementia. This current study further highlights the need to provide focused care to the older adults with dementia or cognitive impairment who have COVID-19.

An Intelligent Virtual-Reality System With Multi-Model Sensing for Cue-Elicited Craving in Patients With Methamphetamine Use Disorder.

Methamphetamine abuse is getting worse amongst the younger population. While there is methadone or buprenorphine harm-reduction treatment for heroin addicts, there is no drug treatment for addicts with methamphetamine use disorder (MUD). Recently, non-medication treatment, such as the cue-elicited craving method integrated with biofeedback, has been widely used. Further, virtual reality (VR) is proposed to simulate an immersive virtual environment for cue-elicited craving in therapy. In this study, we developed a VR system equipped with flavor simulation for the purpose of inducing cravings for MUD patients in therapy. The VR system was integrated with multi-model sensors, such as an electrocardiogram (ECG), galvanic skin response (GSR) and eye tracking to measure various physiological responses from MUD patients in the virtual environment. The goal of the study was to validate the effectiveness of the proposed VR system in inducing the craving of MUD patients via the physiological data. Clinical trials were performed with 20 MUD patients and 11 healthy subjects. VR stimulation was applied to each subject and the physiological data was measured at the time of pre-VR stimulation and post-VR stimulation. A variety of features were extracted from the raw data of heart rate variability (HRV), GSR and eye tracking. The results of statistical analysis found that quite a few features of HRV, GSR and eye tracking had significant differences between pre-VR stimulation and post-VR stimulation in MUD patients but not in healthy subjects. Also, the data of post-VR stimulation showed a significant difference between MUD patients and healthy subjects. Correlation analysis was made and several features between HRV and GSR were found to be correlated. Further, several machine learning methods were applied and showed that the classification accuracy between MUD and healthy subjects at post-VR stimulation attained to 89.8%. In conclusion, the proposed VR system was validated to effectively induce the drug craving in MUD patients.

How to effectively obtain informed consent in trauma patients: a systematic review.

BACKGROUND: Obtaining adequate informed consent from trauma patients is challenging and time-consuming. Healthcare providers must communicate complicated medical information to enable patients to make informed decisions. This study aimed to explore the challenges of obtaining valid consent and methods of improving the quality of the informed consent process for surgical procedures in trauma patients. METHODS: We conducted a systematic review of relevant English-language full-text original articles retrieved from PubMed (1961-August 2018) that had experimental or observational study design and involved adult trauma patients. Studies involving informed consent in clinical or research trials were excluded. Titles and abstracts of searched articles were reviewed and relevant data were extracted with a structured form. Results were synthesized with a narrative approach. RESULTS: A total of 2044 articles were identified in the initial search. Only eight studies were included in the review for narrative synthesis. Six studies involved orthopedic surgeries, one involved nasal bone surgeries, and one involved trauma-related limb debridement. Only one study was conducted in an emergency department. Information recall was poor for trauma patients. Risk recall and comprehension were greater when written or video information was provided than when information was provided only verbally. Patient satisfaction was also greater when both written and verbal information were provided than when verbal information alone was provided; patients who received video information were more satisfied than patients who received written or verbal information. CONCLUSIONS: Many articles have been published on the subject of informed consent, but very few of these have focused on trauma patients. More empirical evidence is needed to support the success of informed consent for trauma patients in the emergency department, especially within the necessarily very limited time frame. To improve the informed consent process for trauma patients, developing a structured and standardized informed consent process may be necessary and achievable; its effectiveness would require evaluation. Adequately educating and training healthcare providers to deliver structured, comprehensive information to trauma patients is crucial. Institutions should give top priority to ensuring patient-centered health care and improved quality of care for trauma patients.

The role of sentrin-specific protease 2 substrate recognition in TGF-ß-induced tumorigenesis.

Smad4, a common-mediator of Smads, plays a central role in forming complexes with receptor-phosphorylated Smads, and then transduces transforming growth factor (TGF)-ß signals into the nuclei. Although many cellular factors are involved in TGF-ß induced epithelial-to-mesenchymal transition (EMT) and cell migration, very little is known with the mechanism of Smad4 regulation on pro-oncogenes response by TGF-ß. Herein, we demonstrate the interaction of Sentrin-specific protease 2 (SENP2) with Smad4 through SENP2 residue 363~400. The same segment is also important for desumoylation of Smad4, and able to relieve sumoylation-mediated TGF-ß repression. The SENP2363~400 segment is critical for TGF-ß-induced cell migration, which is correlated with SENP2363~400 deletion mutant failed to increase matrix metalloproteinase (MMP)-9 and EMT marker gene expression. Moreover, our results suggest that the interaction and desumoylation between SENP2 and Smad4 promote cell migration in triple-negative breast cancer cells. Altogether, our data show how SENP2 regulates its substrate for desumoylation, and also the role of SENP2 in TGF-ß induced cancer cell migration.

Educational video-assisted versus conventional informed consent for trauma-related debridement surgery: a parallel group randomized controlled trial.

BACKGROUND: We investigated whether, in the emergency department (ED), educational video-assisted informed consent is superior to the conventional consent process, to inform trauma patients undergoing surgery about the procedure, benefits, risks, alternatives, and postoperative care. METHODS: We conducted a prospective randomized controlled trial, with superiority study design. All trauma patients scheduled to receive trauma-related debridement surgery in the ED of Kaohsiung Medical University Hospital were included. Patients were assigned to one of two education protocols. Participants in the intervention group watched an educational video illustrating informed consent information, whereas those in the control group read an informed consent document. The primary outcome was knowledge scores and the secondary outcome was assessment of patient satisfaction. A multivariable regression model, with predefined covariates, was used to analyze differences in knowledge scores and patient satisfaction levels between the groups. RESULTS: A total of 142 patients were enrolled, with 70 and 72 assigned to the intervention and control groups, respectively. Mean knowledge scores were higher in the intervention (72.57 ± 16.21 (SD)) than in the control (61.67 ± 18.39) group. By multivariate analysis, the intervention group had significantly greater differences in knowledge scores (coefficient: 7.646, 95% CI: 3.381-11.911). Age, injury severity score, and baseline knowledge score significantly affected the differences in knowledge scores. Significant improvements were observed in patients' perception of statements addressing comprehension of the information provided, helpfulness of the supplied information for decision making, and satisfaction with the informed consent process. Multivariate analysis showed significant correlations between video education and patient satisfaction. CONCLUSIONS: Both the educational approach and severity of injury may have an impact on patient understanding during the informed consent process in an emergency environment. Video-assisted informed consent may improve the understanding of surgery and satisfaction with the informed consent process for trauma patients in the ED. Institutions should develop structured methods and other strategies to better inform trauma patients, facilitate treatment decisions, and improve patient satisfaction. TRIAL REGISTRATION: The ClinicalTrials.gov Identifier is NCT01338480 . The date of registration was April 18, 2011 (retrospectively registered).

Development and pilot testing of an informed consent video for patients with limb trauma prior to debridement surgery using a modified Delphi technique.

BACKGROUND: Ensuring adequate informed consent for surgery in a trauma setting is challenging. We developed and pilot tested an educational video containing information regarding the informed consent process for surgery in trauma patients and a knowledge measure instrument and evaluated whether the audiovisual presentation improved the patients' knowledge regarding their procedure and aftercare and their satisfaction with the informed consent process. METHODS: A modified Delphi technique in which a panel of experts participated in successive rounds of shared scoring of items to forecast outcomes was applied to reach a consensus among the experts. The resulting consensus was used to develop the video content and questions for measuring the understanding of the informed consent for debridement surgery in limb trauma patients. The expert panel included experienced patients. The participants in this pilot study were enrolled as a convenience sample of adult trauma patients scheduled to receive surgery. RESULTS: The modified Delphi technique comprised three rounds over a 4-month period. The items given higher scores by the experts in several categories were chosen for the subsequent rounds until consensus was reached. The experts reached a consensus on each item after the three-round process. The final knowledge measure comprising 10 questions was developed and validated. Thirty eligible trauma patients presenting to the Emergency Department (ED) were approached and completed the questionnaires in this pilot study. The participants exhibited significantly higher mean knowledge and satisfaction scores after watching the educational video than before watching the video. CONCLUSIONS: Our process is promising for developing procedure-specific informed consent and audiovisual aids in medical and surgical specialties. The educational video was developed using a scientific method that integrated the opinions of different stakeholders, particularly patients. This video is a useful tool for improving the knowledge and satisfaction of trauma patients in the ED. The modified Delphi technique is an effective method for collecting experts' opinions and reaching a consensus on the content of educational materials for informed consent. Institutions should prioritize patient-centered health care and develop a structured informed consent process to improve the quality of care. TRIAL REGISTRATION: The ClinicalTrials.gov Identifier is NCT01338480 . The date of registration was April 18, 2011 (retrospectively registered).

The Chinese Version of the Brief Assessment of Cognition in Schizophrenia: Data of a Large-Scale Mandarin-Speaking Population.

OBJECTIVE: The Brief Assessment of Cognition in Schizophrenia (BACS) is a cognitive assessment tool used to measure the broad aspects of cognition that are most frequently impaired in patients with schizophrenia. This study aims to develop the normative data of the Chinese version of the BACS among the Mandarin-speaking population. METHOD: This cross-sectional study included 382 healthy participants (age range: 19-79 years; mean age: 48.0 ± 16.7 years, 47.6% men) in Taiwan, who were evaluated with the BACS. Means and standard deviations of subtests and composite scores were arranged by age group and gender. The Z-scores calculated based on the U.S. norms were compared to our scores based on the norms established in this study. RESULTS: The raw scores of all the BACS tests (verbal memory, digit sequencing, token motor test, verbal fluency, symbol coding, and Tower of London) were negatively correlated with participants' age. Women were superior to men in verbal memory, but inferior to them in executive function. Furthermore, applying the U.S. norms of the BACS to determine the performance of the Chinese BACS results in bias with regard to verbal memory, token motor test, verbal fluency, symbol coding, Tower of London and composite score. CONCLUSIONS: These findings demonstrate that directly applying western cognitive norms to a Mandarin-speaking population can cause biased interpretations. The results of this study can be an important reference for clinical settings and research related to cognitive assessments in Mandarin-speaking Chinese populations.

Surgeon commitment to trauma care decreases missed injuries.

STUDY OBJECTIVE: Missed injuries sustain an important issue concerning patient safety and quality of care. The purpose of this study is to examine the effect of surgeon commitment to trauma care on missed injuries. We hypothesised that surgeons committed to the trauma service has less missed injuries than surgeons not committed to the trauma service would have. METHODS: By retrospective analysis of 976 adult patients admitted to the trauma intensive care unit (ICU) at an urban, university-based trauma centre. Missed injuries were compared between two groups; in group 1 the patients were evaluated and treated by the surgeons who were committed to the trauma service and in group 2 the patients were evaluated and treated by surgeons practicing mainly in other specialties. RESULTS: Patients had significantly lower rates of missed major or life-threatening injuries when treated by group 1 surgeons. Logistic regression model revealed significant factors associated with missed major or life-threatening injuries including ISS and groups in which patients were treated by different group surgeons. CONCLUSIONS: Physicians will perform better when they are trained and interested in a specific area than those not trained, or even not having any particular interest in that specific area. Surgeons committed to the trauma service had less missed injuries in severely injured patients, and it is vital to improve patient safety and quality of care for trauma patients. Staff training and education for assessing severely injured patients and creating an open culture with detection and reduction of the potential for error are important and effective strategies in decreasing missed injuries and improving patient safety.
