Prevalence of anxiety and its risk factors in burn patients: A systematic review and meta-analysis.

The primary objective of this systematic review and meta-analysis was to ascertain the prevalence of anxiety and identify associated risk factors among individuals who have suffered burn injuries. We conducted a thorough and systematic search across various international electronic databases, including Scopus, PubMed and Web of Science, as well as Persian electronic databases like Iranmedex and the scientific information database (SID). Our search encompassed the period from the earliest available records up to 8 August 2023. We employed keywords derived from Medical Subject Headings (MeSH) such as "Prevalence", "Anxiety" and "Burns". In total, 2586 burn patients participated in 13 cross-sectional studies. The mean age of the participants was 32.88 (SD = 2.51). In a compilation of 13 studies, the documented overall occurrence rate of anxiety among burn patients stood at 16.1% (95% CI: 10.0% to 24.7%; I2 = 93.138%; p < 0.001). The outcomes of a meta-regression analysis, which examined the association between anxiety in burn patients and the year of publication, did not uncover any significant correlation (p = 0.442). Furthermore, there was a notable association between anxiety in burn patients and factors such as gender, TBSA affected, educational level and the types of burn injuries. Therefore, healthcare providers need to recognize the substantial prevalence of anxiety in burn patients as a fundamental consideration. This recognition should prompt a proactive approach toward early detection and timely intervention. Developing personalized intervention strategies tailored to each patient's unique risk factors and needs is paramount. These strategies may encompass a range of therapeutic options such as counselling, psychotherapy or consultations with mental health specialists.

Prevalence of surgical site infection and risk factors in patients after knee surgery: A systematic review and meta-analysis.

The present systematic review and meta-analysis aimed to determine the prevalence of surgical site infection (SSI) and risk factors in patients after knee surgery. A comprehensive and systematic search was carried out across various international electronic databases, including Scopus, PubMed and Web of Science, as well as Persian electronic databases like Iranmedex and the Scientific Information Database (SID). This search involved the utilization of keywords derived from Medical Subject Headings, such as 'Prevalence', 'Surgical wound infection', 'Surgical site infection' and 'Orthopaedics', spanning from the earliest records up to 1 October 2023. To assess the quality of the included studies, the Appraisal tool for Cross-Sectional Studies (AXIS tool) was utilized. The study encompassed a combined participant pool of 11 028 individuals who underwent knee surgery across seven selected studies. The collective prevalence of SSI in patients who underwent knee surgery, as reported in the seven included studies, was determined to be 3.0% (95% CI: 1.2% to 7.5%; I2 = 96.612%; p < 0.001). The combined prevalence of SSI in patients with DM, as reported in six studies, was 5.1% (95% CI: 1.7% to 14.5%; I2 = 79.054%; p < 0.001). Similarly, the pooled prevalence of SSI in patients with HTN, drawn from four studies, was 1.8% (95% CI: 0.7% to 4.5%; I2 = 63.996%; p = 0.040). Additionally, the collective prevalence of SSI in patients with a history of tobacco use, based on findings from six studies, was 4.8% (95% CI: 1.4% to 15.2%; I2 = 93.358%; p < 0.001). Subgroup analysis was conducted within six studies, categorizing them by two countries, namely China and the USA. These analyses revealed that the prevalence of SSI following knee surgery was 3.0% in China and 2.0% in the USA. It is noteworthy that variations in SSI prevalence across different studies may be attributed to a multitude of factors, particularly varying risk factors among patient populations. To address this issue and mitigate the impact of SSI on knee surgery patients, it is advisable to develop tailored interventions.

Prevalence of Delirium and Its Related Factors in Burn Patients; a Systematic Review and Meta-Analysis.

Introduction: Considering the importance of delirium disorder in burn patients and its complications, the present systematic review and meta-analysis aimed to determine the prevalence of delirium and its related factors in burn patients. Methods: A comprehensive, systematic search was performed in different international electronic databases, such as Scopus, PubMed, and Web of Science, as well as Persian electronic databases such as Iranmedex, and Scientific Information Database (SID) using keywords extracted from Medical Subject Headings such as "Prevalence", "Delirium", and "Burns" from the earliest to the 17th of July, 2023. Results: In total, 2,710 burn patients participated in ten original studies. Among the participants, 64.6% were male. In the ten studies, the reported pooled prevalence of delirium among burn patients was 20.5% (95% CI: 10.9% to 35.0%; I2=96.889%; P<0.001). Also, factors such as total body surface area, duration of hospitalization, mortality, days on ventilator, alcoholism, benzodiazepine dose, methadone dose, age, male gender, ICU days, operation days, wound care under anesthesia, and opioid dose had a significant correlation with the prevalence of delirium in burn patients. Conclusion: Health managers and policymakers can reduce the prevalence of delirium in burn patients by eliminating or reducing factors associated with it.

Risk predictions of surgical wound complications based on a machine learning algorithm: A systematic review.

Surgical wounds may arise due to harm inflicted upon soft tissue during surgical intervention, and many complications and injuries may accompany them. These complications can lead to prolonged hospitalization and poorer clinical outcomes. Also, Machine learning (ML) is a Section of artificial intelligence (AI) that has emerged in medical care and is increasingly used for diagnosis, complications, prognosis and recurrence prediction. This study aims to investigate surgical wound risk predictions and management using a ML algorithm by R programming language analysis. The systematic review, following PRISMA guidelines, spanned electronic databases using search terms like 'machine learning', 'surgical' and 'wound'. Inclusion criteria covered experimental studies from 1990 to the present on ML's application in surgical wound evaluation. Exclusion criteria included studies lacking full text, focusing on ML in all surgeries, neglecting wound assessment and duplications. Two authors rigorously assessed titles, abstracts and full texts, excluding reviews and guidelines. Ultimately, relevant articles were then analysed. The present study identified nine articles employing ML for surgical wound management. The analysis encompassed various surgical procedures, including Cardiothoracic, Caesarean total abdominal colectomy, Burn plastic surgery, facial plastic surgery, laparotomy, minimal invasive surgery, hernia repair and unspecified surgeries. ML was skillful in evaluating surgical site infections (SSI) in seven studies, while two extended its use to burn-grade diagnosis and wound classification. Support Vector Machine (SVM) and Convolutional Neural Network (CNN) were the most utilized algorithms. ANN achieved a 96% accuracy in facial plastic surgery wound management. CNN demonstrated commendable accuracies in various surgeries, and SVM exhibited high accuracy in multiple surgeries and burn plastic surgery. In sum, these findings underscore ML's potential for significant improvements in postoperative management and the development of enhanced care techniques, particularly in surgical wound management.

Relationship between body mass index and mortality of burns patients: A systematic review and meta-analysis.

This systematic review and meta-analysis aimed to evaluate the relationship between body mass index (BMI) and mortality of burn patients. A comprehensive, systematic search was conducted in different international electronic databases, such as Scopus, PubMed, Web of Science and Persian electronic databases such as Iranmedex, and Scientific Information Database (SID) using keywords extracted from Medical Subject Headings such as "Body mass index", "Burns" and "Mortality" from the earliest to the April 1, 2023. The quality of the studies included in this systematic review was evaluated using the appraisal tool for cross-sectional studies (AXIS tool). Finally, six articles were included in this systematic review and meta-analysis. A total of 16 154 burn patients participated in six studies. Their mean age was 46.32 (SD = 1.99). Of the participants, 71.7% were males. The mean length of hospitalization was 18.80 (SD = 8.08) days, and the average TBSA in burn patients was 38.32 (SD = 2.79) %. Also, the average BMI in burn patients was 27.10 (SD = 1.75). Results found mortality in patients with abnormal BMI (overweight to morbidity BMI) was 0.19 more than normal BMI (ES: 1.19, 95%CI: 0.76-1.87, Z = 0.75, I2 : 71.8%, p = 0.45). Results of linear dose-response showed each 5 kg/m2 increase in BMI was associated with a 5% increase in mortality that was marginally significant (ES: 1.05, 95%CI: 1.00-1.11, Z = 1.99, I2 : 22.2%, p = 0.047). There was a non-linear relationship between levels of BMI and mortality (Prob > χ2 = 0.02). There was an increase in mortality from percentile 10 to 50, although it was not significant (Correlational coefficient: 0.01, p = 0.85). Also, there was an increase in mortality rate from percentile 50 to 90 that was statistically significant (correlational coefficient: 0.06, p = 0.047). Finally, the results of the study indicated BMI can increase the chance of mortality by 0.19, although it was not significant. As a result, more studies are needed to better judge the relationship between BMI and mortality in burn victims.

Prevalence of surgical site infection and risk factors in patients after foot and ankle surgery: A systematic review and meta-analysis.

The present systematic review and meta-analysis aimed to determine the prevalence of surgical site infection (SSI) and related factors in patients after foot and ankle surgery. A comprehensive, systematic search was conducted in different international electronic databases, such as Scopus, PubMed, Web of Science and Persian electronic databases such as Iranmedex and Scientific Information Database (SID) using keywords extracted from Medical Subject Headings such as 'Prevalence', 'Surgical wound infection', 'Surgical site infection' and 'Orthopaedics' from the earliest to 1 June 2023. The appraisal tool for cross-sectional studies (AXIS tool) evaluates the quality of the included studies. A total of 10 447 patients undergoing foot and ankle surgery participated in nine studies. The pooled prevalence of SSI in patients who underwent foot and ankle surgery was reported in nine studies was 4.2% (95% CI: 2.4%-7.2%; I2 = 96.793%; p < 0.001). The odds ratio of SSI prevalence in men was higher than that of women and was significant (OR: 1.335; 95% CI: 1.106-1.612; Z = 3.009; p = 0.003). The pooled prevalence of SSI in patients with hindfoot fracture sites reported in five studies was 4.9% (95% CI: 2.6%-8.9%; I2 = 90.768%; p < 0.001). The pooled prevalence of SSI in patients with diabetes mellitus (DM) reported in six studies was 9.1% (95% CI: 5.6%-14.6%; I2 = 73.957%; p = 0.002). The pooled prevalence of SSI in patients with hypertension (HTN) reported in five studies was 5.5% (95% CI: 2.5%-11.6%; I2 = 91.346%; p < 0.001). The pooled prevalence of SSI in patients with tobacco use reported in eight studies was 6.6% (95% CI: 4.1%-10.4%; I2 = 85.379%; p < 0.001). In general, the existing differences in the prevalence of SSI after foot and ankle surgery in different studies can be based on different risk factors such as comorbidities and gender. Therefore, it is suggested to design appropriate interventions to reduce SSI in these patients.

A systematic review of the exercise effects on burn wound healing.

The emerging evidence has indicated the role of microRNAs (miRNA) in various physiological or pathological processes. Also, documents have suggested that exercise, by affecting miRNA regulation, may enhance burn wound healing. The current study aims to systematically review the role of exercise in regulating miRNAs related to burn wound healing to provide potential therapeutic targets. A comprehensive, systematic search was performed in different international electronic databases, such as Embase, PubMed and Google Scholar search engine, Science Direct, ProQuest and Ovid using keywords extracted from Medical Subject Headings from 2010 to September 2023. The keywords, including 'exercise' AND 'burn wound' AND 'microRNA' and finally, six cases were achieved. Evidence has indicated that exercise may promote the healing of burn wounds by regulating certain miRNAs. Studies have found that exercise regulates the expression of miRNAs such as mir-155, miR-21, let-7a, miR-146a, miR-122 and mir-210 in burn wound tissue, which regulate inflammation and angiogenesis. These findings suggest that miRNAs may play a role in the positive effect of exercise on burn wound healing. However, further research is needed to understand the mechanisms involved fully.

Prevalence of surgical wound infection and related factors in patients after long bone surgery: A systematic review and meta-analysis.

The goal of this systematic review and meta-analysis is to provide an overview of the prevalence of surgical wound infection and related factors in patients after long bone surgery. A comprehensive, systematic search was conducted in different international electronic databases, such as Scopus, PubMed, Web of Science and Persian electronic databases such as Iranmedex and Scientific Information Database using keywords extracted from Medical Subject Headings such as "Prevalence", "Surgical wound infection", "Surgical site infection" and "Orthopedics" from the earliest to the May 1, 2023. The appraisal tool for cross-sectional studies (AXIS tool) evaluates the quality of the included studies. A total of 71 854 patients undergoing long bone surgery participated in 12 studies. The pooled prevalence of surgical wound infection in patients who underwent long bone surgery reported in the 12 studies was 3.3% (95% CI: 1.5%-7.2%; I2 = 99.39%; p < 0.001). The pooled prevalence of surgical wound infection in male and female patients who underwent long bone surgery was 4.6% (95% CI: 1.7%-11.7%; p < 0.001; I2 = 99.34%) and 2.6% (95% CI: 1.0%-6.3%; I2 = 98.84%; p < 0.001), respectively. The pooled prevalence of surgical wound infection in patients with femur surgery sites reported in nine studies was 3.7% (95% CI: 2.1-6.4%; I2 = 93.43%; p < 0.001). The pooled prevalence of surgical wound infection in open and close fractures was 16.4% (95% CI: 8.2%-30.2%; I2 = 95.83%; p < 0.001) and 2.9% (95% CI: 1.5%-5.5%; I2 = 96.40%; p < 0.001), respectively. The pooled prevalence of surgical wound infection in patients with diabetes mellitus (DM), hypertension (HTN) and cardiovascular disease (CVD) was 4.6% (95% CI: 2.3%-8.9%; I2 = 81.50%; p < 0.001), 2.7% (95% CI: 1.2%-6.0%; I2 = 83.82%; p < 0.001) and 3.0% (95% CI: 1.4%-6.4%; I2 = 69.12%; p = 0.006), respectively. In general, the different prevalence of surgical wound infection in patients undergoing surgical treatment after long bone fracture may be caused by underlying factors (gender and co-morbidity) and fracture-related factors (surgery site and type of fracture).

Risk predictions of hospital-acquired pressure injury in the intensive care unit based on a machine learning algorithm.

Pressure injury (PI), or local damage to soft tissues and skin caused by prolonged pressure, remains controversial in the medical world. Patients in intensive care units (ICUs) were frequently reported to suffer PIs, with a heavy burden on their life and expenditures. Machine learning (ML) is a Section of artificial intelligence (AI) that has emerged in nursing practice and is increasingly used for diagnosis, complications, prognosis, and recurrence prediction. This study aims to investigate hospital-acquired PI (HAPI) risk predictions in ICU based on a ML algorithm by R programming language analysis. The former evidence was gathered through PRISMA guidelines. The logical analysis was applied via an R programming language. ML algorithms based on usage rate included logistic regression (LR), Random Forest (RF), Distributed tree (DT), Artificial neural networks (ANN), SVM (Support Vector Machine), Batch normalisation (BN), GB (Gradient Boosting), expectation-maximisation (EM), Adaptive Boosting (AdaBoost), and Extreme Gradient Boosting (XGBoost). Six cases were related to risk predictions of HAPI in the ICU based on an ML algorithm from seven obtained studies, and one study was associated with the Detection of PI risk. Also, the most estimated risksSerum Albumin, Lack of Activity, mechanical ventilation (MV), partial pressure of oxygen (PaO2), Surgery, Cardiovascular adequacy, ICU stay, Vasopressor, Consciousness, Skin integrity, Recovery Unit, insulin and oral antidiabetic (INS&OAD), Complete blood count (CBC), acute physiology and chronic health evaluation (APACHE) II score, Spontaneous bacterial peritonitis (SBP), Steroid, Demineralized Bone Matrix (DBM), Braden score, Faecal incontinence, Serum Creatinine (SCr) and age. In sum, HAPI prediction and PI risk detection are two significant areas for using ML in PI analysis. Also, the current data showed that the ML algorithm, including LR and RF, could be regarded as the practical platform for developing AI tools for diagnosing, prognosis, and treating PI in hospital units, especially ICU.

Prevalence of non-accidental burns and related factors in children: A systematic review and meta-analysis.

Non-accidental burns (NABs) in children had some adverse effects, such as severe burns, requiring skin grafting, and mortality. Previous studies reported NABs in the form of neglect, suspected abuse, and child abuse. Also, different statistics were estimated for the prevalence of NABs in children. Therefore, the current study aimed to comprehensively review and summarise the literature on the prevalence of NABs in children. Also, factors related to NABs as a secondary aim were considered in this review. Keywords combined using Boolean operators and searches were performed in international electronic databases, such as Scopus, PubMed, and Web of Science. Only studies in English were considered from the earliest to 1 March 2023. The analysis was performed using STATA software version 14. Finally, 29 articles were retrieved for the quantitative analysis. Results found that the prevalence of child abuse, suspected abuse, neglect, 'child abuse or suspect abused', and 'abuse, suspect abused, or neglect' was 6% (ES: 0.06, 95% confidence interval [CI]: 0.05-0.07), 12% (ES: 0.12, 95% CI: 0.09-0.15), 21% (ES: 0.21, 95% CI: 0.07-0.35), 8% (ES: 0.08, 95% CI: 0.07-0.09), and 15% (ES: 0.15, 95% CI: 0.13-0.16) among burns victims, respectively. Also, factors related to NABs are categorised into age and gender, agent and area of burns, and family features. Considering the results of the current study, planning for rapid diagnosis and designing a process to manage NABs in children is necessary.

A systematic review of medical science students' knowledge and related factors towards burns first aids.

This systematic review aims to examine the knowledge of medical science students about burn first aid. A comprehensive, systematic search was performed in different international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database (SID) using keywords extracted from Medical Subject Headings such as "Knowledge", "First aid", "Medical science student" and "Burn" from the earliest to February 1, 2023. The quality of the studies included in this systematic review was evaluated by using the appraisal tool for cross-sectional studies (AXIS tool). Thirteen studies had a total of 5046 students studying medical sciences. Among them, 62.24% were female and 77.67% were medical students. The studies included in this systematic review were conducted in Saudi Arabia, Pakistan, Syria, Egypt, and Malaysia. Medical science students' average knowledge of first aid for burns is 56.92 out of 100, which is considered to be a moderate level of knowledge. Factors such as the experience of first aid training, academic year, clinical experience, and economic status had a significant positive relationship with the knowledge of medical science students about first aid for burns. Also, factors such as age, academic specialisation, academic year, information sources, and fathers' occupation had a significant relationship with the knowledge of medical students about first aid for burns. Therefore, it is suggested that healthcare managers and policymakers make the necessary plans to ensure that first aid training courses are implemented during medical science students' studies as a part of their curriculum.

Perceived stigmatisation and reliability of questionnaire in the survivors with burns wound: A systematic review and meta-analysis.

Perceived stigmatisation (PS) can cause different effects on burns survivors such as depression, low self-esteem, body image disturbance, and social anxiety. Current systematic review and meta-analysis aimed to determine the average PS among the burns survivor population and the average reliability of the PS questionnaire (PSQ). A comprehensive systematic search was conducted in various international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database (SID) using keywords extracted from Medical Subject Headings such as "Stigmatisation", "Burns", "Reliability", and "Questionnaire" from the earliest to February 1, 2023. The COSMIN and the Joanna Briggs Institute (JBI) checklists were applied to evaluate the risk of bias. Data analysis was performed in STATA V.14 and JAMOVI v 2.3.24 software. The analysis consisted of two sections. Firstly, the overall weighted average of PS was calculated based on mean and standard deviation. Then, the reliability average of PSQ was calculated with the reliability generalisation method based on the alpha coefficient, questionnaire items, and sample size of each study. Finally, eight articles were included in the quantitative analysis. The results showed the weighted average of PS was 2.14 (ES: 2.14, 95%CI: 1.77-2.51, Z = 11.40, I2 :97.8%, P < 0.001). The average of PS in the factors of confused/staring behaviour, absence of friendly behaviour, and hostile behaviour was 2.36 (ES: 2.36, 95%CI: 2.05-2.67, Z = 14.86, I2 :92.7%, P < 0.001), 2.13 (ES: 2.13, 95%CI: 1.87-2.39, Z = 16.22, I2 :93.8%, P < 0.001) and 2.07 (ES: 2.07, 95%CI: 1.67-2.47, Z = 10.05, I2 :96.5%, P < 0.001), respectively. The analysis showed that the overall coefficient alpha of the PSQ was 0.88 (ES: 0.88, 95%CI: 0.851-0.910, Z = 58.7, I2 : 95.04%, P < 0.001). Also, the alpha coefficient of factors including confused/staring behaviour, absence of friendly behaviour, and hostile behaviour were 0.847 (ES: 0.847, 95%CI: 0.770-0.924, Z = 21.6, I2 :99.13%, P < 0.001), 0.860 (ES: 0.860, 95%CI: 0.808-0.912, Z = 32.4, I2 :98.02%, P < 0.001) and 0.899 (ES: 0.899, 95%CI: 0.829-0.968, Z = 21.33, I2 : 0.0%, P < 0.001), respectively. In sum, the current study showed that the average PS was 2.14 out of 5 points. Most survivors and parents reported confused/starring behaviour as a common perceived behaviour from different individuals. Also, the average reliability of PSQ was 0.88, and it had acceptable reliability. More studies are required to better judge the level of PS among different age groups. Also, the psychometric properties of PSQ in different cultures are an essential issue.

A systematic review of health care workers' knowledge and related factors towards burn first aid.

The present systematic review was conducted to investigate the knowledge of health care workers (HCWs) regarding first aid in burns. A comprehensive, systematic search was performed in different international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Knowledge', 'First aid', 'Health personnel' and 'Burns' from the earliest to 1 February 2023. The appraisal tool for cross-sectional studies (AXIS tool) evaluates the quality of the included studies. A total of 3213 HCWs participated in seven cross-sectional studies. Of the HCWs, 44.50% were physicians. The studies included in this systematic review were conducted in Saudi Arabia, Australia, Turkey, the UK, Ukraine, and Vietnam. The knowledge rate of HCWs related to first aid for burns was 64.78 out of 100, which indicates their relatively desirable knowledge. The factors of first aid training experience, age, and experienced burn traumas had a significant positive effect on the knowledge of HCWs related to first aid for burns. Also, factors such as gender, nationality, marital status, and job position had a significant relationship with the knowledge of HCWs about first aid for burns. Therefore, it is suggested that health care managers and policymakers implement training programs and practical workshops related to first aid, especially first aid for burns.

A systematic review of social support and related factors among burns patients.

Burn injuries, as a major public health problem, can lead to high morbidity and mortality. Burns is considered as one of the most devastating injuries globally and the fourth most common injury after traffic accidents, falls and interpersonal violence. Burn injuries can affect human life, such as physical and mental health, functional skills, and performance. Changes in appearance, social isolation, stress, anxiety, depression, low self-esteem, unemployment, financial burden and family problems can occur in these patients. These burn complications can be exacerbated without adequate social support. This systematic review evaluated burn patients' social support and related factors. A systematic search was performed on the international electronic databases such as Scopus, PubMed, Web of Science and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Burns', 'Social support', 'Perceived social support' and 'Social care' from the earliest to 30 April 2022. The quality of the included studies in this review was assessed using the appraisal tool for cross-sectional studies (AXIS tool). A total of 1677 burn patients were included in this review from 12 studies. Mean score of social support in burn patients based on multidimensional scale of perceived social support, Phillips's social support questionnaire, social support questionnaire, social support scale and Norbeck social support questionnaire were 5.04 (SD = 1.59) of 7, 22.06 (SD = 3.05), 78.20 (SD = 15.00) of 95, 82.24 (SD = 13.70) and 4.14 (SD = 0.99), respectively. Factors such as income, educational attainment, burn surface area, reconstructive surgery, quality of life, self-esteem, socialisation, posttraumatic growth, spirituality, and ego resilience had a significant positive relationship with social support of burns patients. Social support in patients with burn had a significant negative relationship with factors such as psychological distress, having children, life satisfaction, neuroticism and post-traumatic stress disorder. Overall, patients with burns had moderate levels of social support. Therefore, it is recommended that health policymakers and managers make it easier for burn patients to adapt to burns by providing psychological intervention programs and the social support needed by burn patients.

A systematic review of caregivers' knowledge and related factors towards pressure ulcer prevention.

This systematic review aimed to examine the knowledge of caregivers regarding pressure ulcer (PU) prevention. A thorough, methodical search was conducted from the earliest date to February 1, 2023 using keywords extracted from Medical Subject Headings such as "Caregivers", "Knowledge", and "Pressure ulcer" in various international electronic databases such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex and Scientific Information Database. The quality of the studies included in this systematic review was evaluated using an appraisal tool for cross-sectional studies (AXIS tool). In total, 927 caregivers participated in the eight studies. The average age of the participants was 40.50 (SD = 12.67). Among the participants, 61.87% were women. The average caregiver's knowledge of PU prevention was 53.70 (SD = 14.09) out of 100, which suggests a moderate level of knowledge. Factors such as level of education, age, occupation, information about PUs, attitude, and practice had a significant positive relationship with caregivers' knowledge related to the prevention of PUs. Knowledge had a significantly negative relationship with age. In addition, marital status, type of relationship, age, gender, occupation, level of education, and inpatient wards had a significant relationship with caregivers' knowledge regarding PUs prevention. Therefore, managers and policymakers in the medical field can help increase caregivers' knowledge by providing an online or in-person educational platform relevant to PU prevention.

Caregivers' knowledge with burned children and related factors towards burn first aid: A systematic review.

This systematic review aimed to examine the caregivers' knowledge with burned children and related factors towards burn first aid. A comprehensive, systematic search was performed in different international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as "Knowledge", "First aid", "Caregiver", "Burn", and "Child" from the earliest to the December 1, 2022. The quality of the studies included in this systematic review was evaluated by using the appraisal tool for cross-sectional studies (AXIS tool). A total of 11 763 caregivers of children with burns were enrolled in 14 studies. Of the participants, 78.81% were female and 41.15% had a university education. The mean score of caregivers' knowledge with burned children towards burn first aid was 51.44 out of 100. The knowledge of caregivers of burned children towards burn first aid had a significant positive relationship with the level of education, first aid training, age of caregivers, history of burn, number of children, monthly income, social status, and attitude. In addition, caregivers' knowledge had a significant negative relationship with the number of children. Furthermore, there was a significant relationship between caregivers' knowledge and level of education, monthly income, smoking, and previous knowledge of first aid. The level of caregivers' knowledge with burned children towards burn first aid was moderate. Therefore, health managers and policymakers can improve the knowledge of caregivers of burned children towards burn first aid by creating suitable platforms for face-to-face training as well as online training using websites.
