Development and validation of machine learning models to predict frailty risk for elderly

Abstract

Aims

Early identification and intervention of the frailty of the elderly will help lighten the burden of social medical care and improve the quality of life of the elderly. Therefore, we used machine learning (ML) algorithm to develop models to predict frailty risk in the elderly.

Design

A prospective cohort study.

Methods

We collected data on 6997 elderly people from Chinese Longitudinal Healthy Longevity Study wave 6–7 surveys (2011–2012, 2014). After the baseline survey in 1998 (wave 1), the project conducted follow-up surveys (wave 2–8) in 2000–2018. The osteoporotic fractures index was used to assess frailty. Four ML algorithms (random forest [RF], support vector machine, XGBoost and logistic regression [LR]) were used to develop models to identify the risk factors of frailty and predict the risk of frailty. Different ML models were used for the prediction of frailty risk in the elderly and frailty risk was trained on a cohort of 4385 elderly people with frailty (split into a training cohort [75%] and internal validation cohort [25%]). The best-performing model for each study outcome was tested in an external validation cohort of 6997 elderly people with frailty pooled from the surveys (wave 6–7). Model performance was assessed by receiver operating curve and F2-score.

Results

Among the four ML models, the F2-score values were similar (0.91 vs. 0.91 vs. 0.88 vs. 0.90), and the area under the curve (AUC) values of RF model was the highest (0.75), followed by LR model (0.74). In the final two models, the AUC values of RF and LR model were similar (0.77 vs. 0.76) and their accuracy was identical (87.4% vs. 87.4%).

Conclusion

Our study developed a preliminary prediction model based on two different ML approaches to help predict frailty risk in the elderly.

Impact

The presented models from this study can be used to inform healthcare providers to predict the frailty probability among older adults and maybe help guide the development of effective frailty risk management interventions.

Implications for the Profession and/or Patient Care

Detecting frailty at an early stage and implementing timely targeted interventions may help to improve the allocation of health care resources and to reduce frailty-related burden. Identifying risk factors for frailty could be beneficial to provide tailored and personalized care intervention for older adults to more accurately prevent or improve their frail conditions so as to improve their quality of life.

Reporting Method

The study has adhered to STROBE guidelines.

Effect of quality nursing care on wound pain and anxiety in burn patients: A meta‐analysis

Abstract

To systematically evaluate the effects of quality nursing care on wound pain and anxiety in burn patients. Computerised searches of PubMed, Google Scholar, Cochrane Library, Embase, Wanfang, China Biomedical Literature Database and China National Knowledge Infrastructure databases randomised controlled trials (RCTs) on the application of quality nursing care to burn patients were carried out from database inception to October 2023. Literature was screened and evaluated by two researchers based on inclusion and exclusion criteria, and data were extracted from the final included literature. Stata 17.0 software was employed for data analysis. Overall, 15 RCTs and 1115 burn patients were included, including 563 and 552 in the quality care and routine care groups. It was found that, compared with routine care, burn patients who implemented quality care had significantly less wound pain (SMD: −1.79, 95% CI: −2.22 to −1.36, p < 0.001), anxiety (SMD: −2.71. 95% CI: −3.49 to −1.92, p < 0.001) and depression (SMD: −1.74, 95% CI: −2.35 to −1.14, p < 0.001) levels were significantly reduced post-trauma.

Risk factors for amputation in diabetic foot ulcers: A retrospective analysis

Abstract

Diabetic foot ulcers (DFUs) are chronic, difficult-to-heal wounds with a very high incidence of amputation. For patients with DFUs, prevention of amputation is crucial. However, the risk factors associated with DFU amputation and the extent to which different risk factors increase the risk of amputation are still uncertain. This study intends to provide a clinical basis for early intervention in DFU by retrospectively analysing the risk factors for DFU amputation. A retrospective analysis of 200 patients with DFUs admitted between October 2019 and October 2023 was conducted. Sixty-eight of the 200 underwent amputations. The overall amputation rate was 34%. Multiple logistic regression model showed that neutrophil/lymphocyte ratio (OR = 1.943; 95% CI:1.826–2.139), white blood cell (OR = 1.143; 95% CI:1.034–1.267), C-reactive protein (OR = 1.307; 95% CI:1.113–2.194) and Wagner grading (OR = 2.783; 95% CI: 1.751–4.302) were independent risk factors for amputation, while haemoglobin (OR = 0.742; 95% CI:0.638–0.965) and high density lipoprotein were independent protective factors for amputation (OR = 0.168; 95% CI:0.037–0.716), and further Receiver Operating Characteristic Curve curves showed that they showed high accuracy and were good predictors of amputation of DFUs.

The impact of long‐term antihypertensive treatment on wound healing after major non‐cardiac surgery in patients with cardiovascular diseases: A meta‐analysis

Abstract

Hypertension is a prevalent condition that poses significant challenges in the perioperative management of patients undergoing major non-cardiac surgery, particularly concerning wound healing and scar formation. This meta-analysis assesses the impact of long-term antihypertensive treatment on postoperative wound healing, examining data from seven studies involving patients who received such treatments compared to untreated controls. Our findings reveal that long-term antihypertensive therapy is associated with significantly improved wound healing outcomes, as indicated by lower REEDA scores (I 2 = 96%, SMD = −25.71, 95% CI: [−33.71, −17.70], p < 0.01) 1 week post-surgery and reduced scar formation, demonstrated by lower Manchester Scar Scale scores (I 2 = 93%, SMD = −37.29, 95% CI: [−44.93, −29.64], p < 0.01) 2 months post-surgery. These results underscore the potential benefits of antihypertensive treatment in enhancing surgical recovery and offer insights into optimising perioperative care for hypertensive patients.

Early warning scores for sepsis identification and prediction of in‐hospital mortality in adults with sepsis: A systematic review and meta‐analysis

Abstract

Aim

The early warning scores (EWS), quick Sequential Organ Failure Assessment (qSOFA) and systemic inflammatory response syndrome (SIRS) criteria have been proposed as sepsis screening tools. This review aims to summarise and compare the performance of EWS with the qSOFA and SIRS criteria for predicting sepsis diagnosis and in-hospital mortality in patients with sepsis.

Design

A systematic review with meta-analysis.

Review Methods

Seven databases were searched from January 1, 2016 until March 10, 2022. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Sensitivity, specificity, likelihood ratios and diagnostic odd ratios were pooled by using the bivariate random effects model. Overall performance was summarised by using the hierarchical summary receiver–operating characteristics curve. This paper adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Diagnostic Test Accuracy Studies (PRISMA-DTA) guidelines.

Results

Ten studies involving 52,474 subjects were included in the review. For predicting sepsis diagnosis, the pooled sensitivity of EWS (65%, 95% CI: 55, 75) was similar to SIRS ≥2 (70%, 95% CI: 49, 85) and higher than qSOFA ≥2 (37%, 95% CI: 20, 59). The pooled specificity of EWS (77%, 95% CI: 64, 86) was higher than SIRS ≥2 (62%, 95% CI: 41, 80) but lower than qSOFA ≥2 (94%, 95% CI: 86, 98). Results were similar for the secondary outcome of in-hospital mortality.

Conclusions

Although no one scoring system had both high sensitivity and specificity, the EWS had at least equivalent values in most measures of diagnostic accuracy compared with SIRS or qSOFA.

Implications for the profession

Healthcare systems in which EWS is already in place should consider whether there is any clinical benefit in adopting qSOFA or SIRS.

Effects of loose combined cutting seton surgery on wound healing and pain in patients with high anal fistula: A meta‐analysis

Abstract

A meta-analysis was conducted to evaluate the effects of loose combined cutting seton surgery on wound healing and pain in patients with high anal fistula, aiming to provide evidence-based medical evidence for surgical method selection for these patients. A comprehensive computerized search of PubMed, Cochrane Library, EMBASE, Wanfang and China National Knowledge Infrastructure databases was conducted to collect all relevant studies published up to November 2023, evaluating the effects of loose combined cutting seton surgery in treating patients with high anal fistulas. Two researchers independently screened, extracted data, and assessed the quality of the identified studies. RevMan 5.4 software was employed for data analysis. Overall, 16 articles were included, comprising 1124 patients, with 567 undergoing loose combined cutting seton surgery and 557 undergoing simple cutting seton surgery. The analysis revealed patients undergoing loose combined cutting seton surgery had a higher rate of postoperative wound healing (97.44% vs. 81.69%, odds ratio [OR]: 7.49, 95% confidence interval [CI]: 4.29–13.10, p < 0.00001), shorter wound healing time (standardized mean differences [SMD]: −1.48, 95% CI: −1.89 to −1.08, p < 0.00001), lower postoperative wound pain scores (SMD: −2.51, 95% CI: −3.51 to −1.51, p < 0.00001), and a lower rate of postoperative complications (3.43% vs. 20.83%, OR: 0.13, 95% CI: 0.05–0.31, p < 0.00001). The current evidence suggests that compared to simple cutting seton surgery, loose combined cutting seton surgery in treating high anal fistulas can promote postoperative wound healing, shorten wound healing time, alleviate pain, and reduce the incidence of postoperative complications, making it a worthy clinical practice for widespread application.

Effects of enhanced recovery after surgery nursing program on the surgical site wound infection and postoperative complications in patients of gastric cancer: A meta‐analysis

Abstract

This meta-analysis systematically evaluates the impact of the enhanced recovery after surgery (ERAS) concept on surgical site wound infections and postoperative complications in gastric cancer patients. A comprehensive computerized search was conducted in PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases for randomized controlled trials (RCTs), from database inception to November 2023, exploring the application of the ERAS concept in the perioperative period of gastric cancer surgery. Two researchers independently screened the literature, extracted data, and conducted quality assessments based on inclusion and exclusion criteria. Data analysis was performed using Stata 17.0 software. A total of 24 RCTs involving 2050 gastric cancer patients were included. The analysis revealed a significantly lower incidence of wound infections (OR = 0.23, 95% CI: 0.14–0.40, p < 0.001) and postoperative complications (OR = 0.20, 95% CI: 0.15–0.27, p < 0.001) in the ERAS group compared to the standard care group. This study demonstrates that the application of the ERAS concept during the perioperative period in gastric cancer surgery can effectively reduce the occurrence of wound infections and complications, thereby facilitating postoperative recovery.

The influence of minimally invasive esophagectomy on wound infection in patients undergoing esophageal cancer surgery: A meta‐analysis

Abstract

The impacts of minimally invasive esophagectomy (MIE) in comparison with open esophagectomy (OE) on postoperative complications, wound infections and hospital length of stay in patients with esophageal carcinoma (ESCA) using meta-analysis to provide reliable evidence for clinical practice. A search strategy was developed and computer searches were performed on Embase, Web of Science, PubMed, Cochrane Library, Wanfang, China Biomedical Literature Database and China National Knowledge Infrastructure databases for clinical studies that reported the effects of MIE in comparison with OE in patients with ESCA. The retrieval time was from their inception to October 2023. Two authors independently performed literature screening, and data extraction and literature quality evaluation were performed separately for the included studies. Meta-analysis was performed using Stata 17.0 software. Overall, 26 studies with 2427 ESCA patients were included in this study, of which 1203 were in the MIE group and 1224 were in the OE group. The results showed that, compared with OE, ESCA patients who underwent MIE were less likely to develop postoperative wound infections (odds ratio [OR] = 0.31, 95% confidence intervals [CIs]: 0.20–0.49, p < 0.001) and complications (OR = 0.23, 95% CI: 0.18–0.30, p < 0.001) and have a shorter hospital stay (standardized mean difference = −1.93, 95% CI: −2.38 to −1.48, p < 0.001). MIE has advantages over OE in terms of shorter hospital stay and reduced incidence of postoperative wound infections and complications.

Are current wound classifications valid for predicting prognosis in people treated for limb‐threatening diabetic foot ulcers?

Abstract

This study aims to investigate whether the current wound classifications were valid for the treatment prognosis of subjects treated for limb-threatening diabetic foot ulcers (LTDFU). A total of 1548 patients with LTDFU and infection were studied, with wounds recorded using the Wagner, Texas, PEDIS and WIfI classifications while major lower extremity amputations (LEAs) or in-hospital mortality incidences were defined as poor outcomes. Among them, 153 (9.9%) patients received major LEAs and 38 (2.5%) patients died. After adjustments, the Wagner classification and Texas stage as well as clinical factors such as comorbidity with major adverse cardiac events (MACE), being under dialysis and having serum levels of C-reactive protein (CRP) and albumin were independent factors for prognosis. For patients without dialysis, Wagner and Texas stage stood out independently for prognosis. For patients on dialysis, only levels of CRP (odds ratio [OR] = 2.2 in Wagner, OR = 2.0 in WIfI, OR = 2.2 in Texas, OR = 2.3 in PEDIS) and albumin (OR = 0.4 in four classifications) were valid predictors. The Wagner system and Texas stage were valid for predicting prognosis in treatment for LTDFUs, suggesting a role of vascular perfusion. MACE history, levels of CRP and albumin level should assist in prediction; more significantly, only levels of CRP and albumin appeared valid for those subjects undergoing dialysis.

Por: Lu Wang · Wei Liu · Sitong Bi · Li Zhou · Lihua Li

by Lu Wang, Wei Liu, Sitong Bi, Li Zhou, Lihua Li

Background

The roles of minerals in obesity received increasing attention recently due to its oxidant or antioxidant functions and effects on insulin and glucose metabolism that may be associated with obesity. Herein, this study aims to explore the association between minerals and obesity and body mass index (BMI) in children with different ages, and hope to provide some references for prevention and management in children with high-risk of obesity.

Methods

Data of children aged 2–17 years old were extracted from the National Health and Nutrition Examination Survey (NHANES) database in 2007–2014 in this cross-sectional study. Weighted univariate and multivariate logistic regression and liner regression analyses were used to screen covariates, and explore the association between minerals [including calcium (Ca), phosphorus (P), magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu), sodium (Na), potassium (K) and selenium (Se)] and childhood obesity and BMI. The evaluation indexes were β, odds ratios (ORs) and 95% confidence intervals (CIs). These relationships were also investigated in age subgroups.

Results

Among 10,450 eligible children, 1,988 (19.02%) had obesity. After adjusting for covariates, we found the highest quartile of dietary Fe [OR = 0.74, 95%CI: (0.58, 0.95)] and Zn [OR = 0.70, 95%CI: (0.54, 0.92)] intakes were associated with low odds of childhood obesity, while that of dietary Na intake seemed to be positively linked to childhood obesity [OR = 1.35, 95%CI: (1.05, 1.74)]. High dietary intakes of Ca, Na and K were positively associated with children’s BMI, on the contrary, dietary Fe and Zn consumptions had a negative one (all PP Conclusion

Dietary Fe and Zn intakes played positive roles in reducing childhood obesity or BMI, while the intakes of Na should be controlled suitably.

Notoginsenoside R1 attenuates brain injury in rats with traumatic brain injury: Possible mediation of apoptosis via ERK1/2 signaling pathway

by Xiaoxian Pei, Ling Zhang, Dan Liu, Yajuan Wu, Xiaowei Li, Ying Cao, Xiangdong Du

Traumatic brain injury (TBI) occurs worldwide and is associated with high mortality and disability rate. Apoptosis induced by TBI is one of the important causes of secondary injury after TBI. Notoginsenoside R1 (NGR1) is the main phytoestrogen extracted from Panax notoginseng. Many studies have shown that NGR1 has potent neuroprotective, anti-inflammatory, and anti-apoptotic properties and is effective in ischemia-reperfusion injury. Therefore, we investigated the potential neuroprotective effects of NGR1 after TBI and explored its molecular mechanism of action. A rat model of TBI was established using the controlled cortical impact (CCI) method. The expression levels of Bcl-2, Bax, caspase 3, and ERK1/2-related molecules in the downstream pathway were also detected by western blotting. The expression levels of pro-inflammatory cytokines were detected by real-time quantitative PCR. Nissl staining was used to clarify the morphological changes around the injury foci in rats after TBI. Fluoro-Jade B (FJB) and terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling (TUNEL) fluorescence staining were used to detect the apoptosis of neural cells in each group of rats. The results showed that NGR1 administration reduced neurological deficits after TBI, as well as brain edema and brain tissue apoptosis. It also significantly inhibited the expression of pro-inflammatory cytokines. Furthermore, NGR1 decreased the expression levels of extracellular signal-regulated kinase (ERK) and p-RSK1, which are phosphorylated after trauma. This study suggests that NGR1 can improve neuronal apoptosis in brain injury by inhibiting the ERK signaling pathway. NGR1 is a potential novel neuroprotective agent for the treatment of secondary brain injury after TBI.

Effect of humanised care on the surgical site wound infection after caesarean: A meta‐analysis

Abstract

Herein, a meta-analysis was conducted to systematically evaluate the effect of humanised care on maternal postoperative wound infections in patients who underwent caesarean section. A computerised search of Embase, Cochrane Library, PubMed, Web of Science, China National Knowledge Infrastructure, Chinese Biomedical Literature Database and Wanfang database was performed, supplemented by a manual search from database inception to September 2023, to collate randomised controlled trials (RCTs) regarding the application of humanised care during the perioperative period of caesarean section. Two researchers screened and selected studies identified according to inclusion and exclusion criteria, and the included literature was evaluated for quality, extracted information and required data. Data analysis was performed using RevMan 5.4 software. Twenty RCTs comprising 2408 patients were included. The results revealed the humanised care group had a lower incidence of postoperative wound infections (0.83% vs. 4.32%, odds ratio [OR]: 0.26, 95% confidence interval [CI]: 0.15–0.46, p < 0.00001) and fewer postoperative complications than the conventional care group (4.32% vs. 16.35%, OR: 0.23, 95% CI: 0.16–0.31, p < 0.00001), with lower anxiety scores (standardised mean difference [SMD]: −3.15, 95% CI: −3.90 to −2.40, p < 0.00001) and depression scores (SMD: −3.68, 95% CI: −4.49 to −2.88, p < 0.00001). The application of humanised care during the perioperative period of caesarean section can prevent postoperative wound infection, reduce postoperative complications and help alleviate maternal anxiety and depression, which is worthy of clinical promotion and application.

Knowledge, attitudes and practices towards advance directives among clinical nurses: Multicenter cross‐sectional survey

Abstract

Aims and Objectives

This study aimed to describe the knowledge, attitudes and practices (KAP) of nurses in implementing advance directives (ADs) for older patients and analyze the influencing factors before the establishment of the first advance directives act in China.

Design

Multicenter cross-sectional survey. The standards for reporting the STROBE checklist are used.

Methods

This cross-sectional study developed a self-designed structured questionnaire to assess nurses' knowledge, attitudes and practices about ADs. Nurses were recruited by stratified random sampling through the Nursing Departments of 12 hospitals in southwest China and were asked to fill out the questionnaire face to face about knowledge, attitudes and practices. Data were analyzed following descriptive statistics, rank-sum test and multiple linear regression.

Results

This study included 950 nurses. The study found that nurses were extremely supportive of ADs. Unmarried nurses had better knowledge of ADs than married ones. Nevertheless, there was a discrepancy between the participants' knowledge, attitude and practice. The participants' practice was lower (4.3%) compared with their attitude (81.9%) and knowledge (42.2%). Knowledge on, attitudes towards and standardized procedures for ADs in the workplace affected nursing practice.

Conclusions

The study recommends that courses on ADs and appropriate support from medical institutions should be provided to nurses to increase their knowledge and confidence in implementing ADs. Healthcare professionals should be sufficiently equipped to implement ADs and handle their execution appropriately to provide adequate end-of-life care corresponding to patients' wishes.

Relevance to Clinical Practice

The study results inform rich insights as it discusses the numerous interrelating factors influencing these three fundamental aspects that affect the success of any AD policy by surveying the knowledge, attitudes and practices of clinical nurses. Furthermore, our results hint at distinct areas of improvement in the nursing practice to facilitate the wider implementation and acceptance of ADs in China.

A hybrid systematic narrative review of instruments measuring home‐based care nurses' competency

Abstract

Aim

The aim of the study was to identify and synthesize the contents and the psychometric properties of the existing instruments measuring home-based care (HBC) nurses' competencies.

Design

A hybrid systematic narrative review was performed.

Review Methods

The eligible studies were reviewed to identify the competencies measured by the instruments for HBC nurses. The psychometric properties of instruments in development and psychometric testing design studies were also examined. The methodological quality of the studies was evaluated using the Medical Education Research Study Quality Instrument and COSMIN checklist accordingly.

Data Sources

Relevant studies were searched on CINAHL, MEDLINE (via PubMed), EMBASE, PsychINFO and Scopus from 2000 to 2022. The search was limited to full-text items in the English language.

Results

A total of 23 studies reporting 24 instruments were included. 12 instruments were adopted or modified by the studies while the other 12 were developed and psychometrically tested by the studies. None of the instruments encompassed all of the 10 home-based nursing care competencies identified in an earlier study. The two most frequently measured competencies were the management of health conditions, and critical thinking and problem-solving skills, while the two least measured competencies were quality and safety, and technological literacy. The content and structural validity of most instruments were inadequate since the adopted instruments were not initially designed or tested among HBC nurses.

Conclusion

This review provides a consolidation of existing instruments that were used to assess HBC nurses' competencies. The instruments were generally not comprehensive, and the content and structural validity were limited. Nonetheless, the domains, items and approaches to instrument development could be adopted to develop and test a comprehensive competency instrument for home-based nursing care practice in the future.

Impact

This review consolidated instruments used to measure home-based care nurses' competency. The instruments were often designed for ward-based care nurses hence a comprehensive and validated home-based nursing care competency instrument is needed. Nurses, researchers and nursing leaders could consider the competency instruments identified in this review to measure nurses' competencies, while a home-based nursing care competency scale is being developed.

Patient or Public Contribution

No patient or public contribution was required in this review.

Interprofessional collaboration in telemedicine for long‐term care: An exploratory qualitative study

Abstract

Background

Widespread and sustained adoption of telemedicine in long-term residential care is emerging. Nursing home (NH) nurses play a key role in collaborating with remote physicians to manage residents' medical conditions through videoconferencing. Therefore, understanding of interprofessional collaboration and effective communication between nurses and physicians is critical to ensure quality of care and safety during teleconsultations.

Aims

To explore NH nurses' and physicians' experiences of interprofessional collaboration and communication during teleconsultations.

Methods

A qualitative descriptive design was adopted. Purposive sampling was conducted to recruit 22 physicians and nurses involved in NH teleconsultations. Semi-structured online interviews were conducted, and data were thematically analyzed.

Results

Three themes were identified: (1) Manner of communication in telemedicine, (2) sociocultural influences in collaborative practice, and (3) role expectations in telemedicine. Both nurses and physicians recognized the importance of building and maintaining trust as physicians heavily depended on nurses for provision of objective information for clinical decision-making. However, practice differences were observed between nurses and physicians during teleconsultations. Sociocultural influences such as power relations and language barriers also affected the nurse–physician relationship and interpersonal communication. Additionally, different performance expectations were identified between nurses and physicians.

Conclusion

Interprofessional collaboration in teleconsultations is challenging because of lack of in-person assessment and dependence on nurses for clinical information. In addition, expectations and communication styles differ among healthcare professionals. This study called for interprofessional telemedicine training with incorporation of shared mental models to improve role clarity and communication. Given the international-dominated healthcare workforce in long-term care, the development of cultural competency could also be considered in telemedicine training to enhance nurse–physician collaborative practice.

Clinical Relevance

Telemedicine is increasingly adopted in long-term care settings, where multidisciplinary healthcare professionals from different health institutions are involved in resident care. Interprofessional collaboration should be incorporated into telehealth education for enhanced clinical practice in this care delivery model.
