Impact of malnutrition in surgically repaired hip fracture patients admitted for rehabilitation in a community hospital: A cohort prospective study

Etiological factors and clinical outcomes in extracapsular and intracapsular hip fractures among older adults: A gender-specific analysis

BACKGROUND

Compared to patients with intracapsular fractures (ICFs), those with extracapsular fractures (ECFs) had worse outcomes. However, most studies of risk factors for these fractures lacked relevant potential reasons, particularly nutritional status, and adjustment for confounding factors. Furthermore, less is known about their effects on clinical outcomes.

OBJECTIVE

To conduct a gender-specific analysis of community-dwelling individuals admitted with hip fractures to examine the association of clinical risk factors and health care measures.

DESIGN

Monocentric cross-sectional study.

SETTING

Orthopedic trauma department.

PARTICIPANTS

A total of 787 women and 318 men of similar mean age (±SD): 83.1 years (±8.6) and 82.5 years (±9.0), respectively.

MAIN OUTCOME MEASURES

Multivariable logistic regression analyzed risk factors including age, gender, dementia, stroke, ischemic heart disease, diabetes, prefracture mobility, alcohol consumption, American Society of Anesthesiologists grades, drug history, and nutrition status for assessing risk factors and outcomes associated with ECFs and ICFs.

RESULTS

Compared to ICFs, for each additional year of age, women had a 3% and men 4% greater association with ECFs. Among women only, ECFs were associated with risk of malnutrition: odds ratio [OR] = 1.70 (95% CI, 1.17-2.48) or malnourishment: OR = 1.93 (95% CI, 1.06-3.52), stroke: OR = 1.85 (95% CI, 1.16-2.97), and diabetes: OR = 1.92 (95% CI, 1.21-3.06). Women with ECFs were less likely to be discharged to their own homes: OR = 0.56 (95% CI, 0.38-0.83); but more likely to be discharged to a rehabilitation unit: OR = 1.81 (95% CI, 1.21-2.71) and readmitted to hospital within 30 days of discharge ≥1 time: OR: 2.39 (95% CI, 1.27-4.50) or ≥2 times: OR = 3.48 (95% CI, 1.05-11.57): they did not differ in discharge to residential or nursing care or in-hospital mortality. Among men, there were no differences in discharge destinations or readmissions between types of fractures.

CONCLUSIONS

Compared to ICFs, a greater number of risk factors associated with ECFs were identified more often in women than in men, and ECFs also have greater influences on clinical outcomes in women.

The Psychological, Cognitive, and Behavioural Effects of Starvation in Humans: A Scoping Review

BACKGROUND

Research has highlighted the physical complications of starvation, but there is less research examining the psychological effects of starvation in humans.

AIMS

This scoping review synthesises literature on the non-physical effects of starvation in humans.

METHOD

Following PRISMA-ScR guidelines, we searched MEDLINE, PsycINFO, and Global Health for studies published between 1946 and 2023 examining the non-physical effects of starvation in individuals aged 2-79 years, including those who were starved, malnourished, stunted, wasted, underweight, had a restrictive eating disorder, or were raised in famine conditions.

RESULTS

From 16,555 abstracts, 851 articles on the effects of malnutrition were reviewed, and 318 were included. Among these, 35% focused on children and adolescents, 25.5% on adults with comorbid illnesses, 17% on older adults, 13% on those with eating disorders, 6% on adults without comorbidities, and 3.5% on famine survivors. Cognitive impairments were the most frequently reported effects in children. In adults and older adults, depression and anxiety were common, along with reduced cognitive functioning, reduced quality of life, social withdrawal, impaired sleep and impaired sexual functioning. Individuals with eating disorders experienced depression, anxiety, obsessive-compulsive symptoms, emotion regulation difficulties, and cognitive impairment.

CONCLUSIONS

There is extensive evidence showing the detrimental non-physical consequences of starvation in children and adults. These findings should inform research, clinical interventions, and educational materials addressing the effects of insufficient nutrition, including in those with restrictive eating disorders.

Correlation Analysis Between the Geriatric Nutritional Risk Index Hip Fracture in Male: Based on the National Health and Nutrition Examination Survey Database

Hip fractures (HFs) are common in elderly patients and are associated with high mortality rates and functional impairment. Malnutrition has been shown to negatively impact postoperative survival rates in HF patients. However, the relationship between the Geriatric Nutrition Risk Index (GNRI) and the risk of HF remains unclear. This study aims to evaluate the association between GNRI and HF risk, with a particular focus on the elderly male population.We conducted a cross-sectional study using data from the National Health and Nutrition Examination Survey (NHANES) for the periods 2007-2010, 2013-2014, and 2017-2018. Through multivariate regression analysis, we assessed the association between GNRI and HF and performed stratified and subgroup analyses to further explore this relationship. Additionally, we utilized restricted cubic splines (RCSs) to investigate the potential nonlinear relationship between GNRI and HF risk.The study found that gender significantly influenced the relationship between GNRI and HF (p for interaction = 0.002). In males, GNRI was significantly negatively associated with the risk of HF (OR < 1, p < 0.05). RCS analysis showed that the relationship between GNRI and HF risk in elderly males might be linearly negative. The critical threshold for GNRI was identified as 104.14, beyond which the risk of HF significantly decreased.This study demonstrates a linear negative correlation between GNRI and the risk of HF in elderly males, with a GNRI of 104.14 identified as the critical threshold for predicting the risk of hip fractures.

Prevalence, incidence, and complications of malnutrition in severely injured patients

BACKGROUND

Severely injured patients may suffer from acute disease-related or injury-related malnutrition involving a marked inflammatory response. This study investigated the prevalence and incidence of malnutrition and its relation with complications in severely injured patients admitted to the intensive care unit (ICU).

METHODS

This observational prospective cohort study included severely injured patients (Injury Severity Score ≥ 16), admitted to the ICU of five level-1 trauma centers in the Netherlands and United States. Malnutrition was defined as a Subjective Global Assessment score ≤ 5. Complications included systemic-, surgery-, and fracture-related complications, pneumonia, urinary tract infection, deep venous thrombosis, and pulmonary embolism. In-ICU and in-hospital mortality were recorded separately. The complication rate was compared between patients who had or developed malnutrition and patients who remained well-nourished, using multivariable logistic regression analysis.

RESULTS

Of 100 included patients, twelve (12%) were malnourished at admission. Of the 88 well-nourished patients, 44 developed malnutrition during ICU admission, (ICU incidence 50%, 95% confidence interval [CI] 40-60%). Another 18 patients developed malnutrition at the ward (overall in-hospital incidence 70%, 95% CI 61-80%). The 62 patients who developed malnutrition and 12 patients who were malnourished upon admission had more complications than the 26 patients who remained well-nourished (58% vs. 50% vs. 27% respectively; p = 0.03; Odds Ratio 3.4, 95% CI 1.2-9.6).

CONCLUSIONS

50% of severely injured patients developed malnutrition during ICU admission, increasing to 70% during hospital admission. Malnutrition was related to an increased risk of complications. Recognition of sub-optimally nourished severely injured patients and assessment of nutritional needs could be valuable in optimizing their clinical outcomes.

Models of community hospitals and state of research in high-income countries: a scoping review

Introduction

Existing literature have not reviewed the growing spectrum of care models in Community Hospitals (CH) along with the scope of research. We fill this gap by reviewing CHs models in high-income countries.

Methods

We conducted a scoping review according to Arksey & O'Malley's framework. We searched for articles published between January 2016 to April 2024 in EMBASE, PubMed, and Scopus. Additional studies were identified through snowballing.

Results

470 studies were included in the review. CHs models in 22 countries were categorized based on healthcare services provided and target patient populations. CHs in 18 countries were found to provide COVID-19 services. CHs in eight countries primarily provide post-acute and rehabilitative services. 40 articles were extracted to synthesize research themes in CHs providing post-acute care. Majority focused on assessing the healthcare needs of patient populations. Other domains include program efficacy, research and educational needs of staff, clinical guidelines reviews, and the community's role in supporting CHs.

Conclusion

CHs evolve to meet changing healthcare needs and understanding the state of CHs research would inform potential research directions. Future studies could explore the relationship between post-acute settings and the community, and strategies to enhance staff capability and address barriers to conducting research in post-acute settings.

Nutritional care in older adults: are we doing everything? An expert opinion review

Malnutrition is a prevalent, yet often underdiagnosed and undertreated, condition in older adults. It is characterized by weight loss and/or reduced muscle mass due to diminished caloric intake, inflammation, and/or disease burden. In return, malnutrition can lead to diminished skeletal muscle functionality and disability, among others. Malnutrition plays a crucial role in the pathogenesis of two prevalent geriatric syndromes, namely sarcopenia and frailty. The complex interplay between malnutrition, sarcopenia, and frailty significantly impacts the older population, leading to increased morbidity, mortality, hospitalization rates, quality-of-life, and healthcare costs. Given the prognostic significance of malnutrition in geriatric care, recent guidelines emphasized the role of nutritional support in vulnerable populations. A group of vulnerable populations to malnutrition, sarcopenia, and frailty are older patients with hip fractures, cancer patients, and those with sarcopenic dysphagia. This article highlights the importance of individualized nutritional assessment and treatment in the management of vulnerable populations such as older patients with hip fractures, cancer, and those suffering from sarcopenic dysphagia. It presents practical protocols and guidelines that can be instrumental in enhancing the nutritional care of these groups, thereby improving their overall health outcomes.

Geriatric nutritional risk index predicts postoperative prognosis in older patients with hip fracture: A meta-analysis

BACKGROUND

Hip fracture is common in elderly individuals and is accompanied by a relatively high mortality rate. However, it is currently difficult to accurately predict postoperative prognosis for older patients with hip fractures. The aim of this meta-analysis was to further determine the prognostic value of the geriatric nutritional risk index (GNRI) for patients who underwent hip fracture surgery.

METHODS

The Medline, EMBASE, Web of Science, and CNKI databases were searched up to September 19, 2023, for available studies. The primary and secondary outcomes were the mortality and complication rates, respectively. Hazard ratios (HRs) and relative risks with corresponding 95% confidence intervals (CIs) were separately combined to assess the associations between the GNRI and mortality and complication rates. All the statistical analyses were performed with STATA 15.0 and SPSS 22.0 software.

RESULTS

A total of 9 studies with 3959 patients were included. The pooled results demonstrated that a lower GNRI was significantly related to an increased risk of postoperative mortality (HR = 0.82, 95% CI = 0.72-0.92, P = .001). In addition, the GNRI predicted the risk of overall postoperative complications (52% vs 35.5%, P = .04) and pneumonia (33.3% vs 13.6%, P = .010).

CONCLUSION

The GNRI might serve as a novel prognostic indicator for older patients with hip fractures, and a lower GNRI indicates an increased risk of postoperative mortality and complication rates.

Challenges in Delivering Effective Care for Older Persons with Fragility Fractures

Fragility fractures occur because of low-impact trauma or even spontaneously in individuals with osteoporosis. Caring for older persons with fragility fractures can present several challenges due to the unique needs and vulnerabilities of this population. Older individuals commonly have multiple medical conditions, such as osteoporosis, arthritis, cardiovascular diseases, and diabetes. These comorbidities can complicate fracture management and increase the risk of complications. Fracture repair through surgery may be more complex in older patients due to poor bone quality, decreased tissue elasticity, and higher chances of anesthesia complications. In addition, mobility and functional limitations post-fracture are highly prevalent in this population, affecting their independence and increasing their risk of institutionalization. Addressing these challenges requires a multidisciplinary approach involving orthopedic surgeons, geriatricians, physical and rehabilitation physicians, physiotherapists, occupational therapists, dieticians, social workers, and caregivers. Preventive measures, such as fall prevention strategies and osteoporosis management, can also play a vital role in reducing the incidence of fragility fractures in older persons.

Concurrent Negative Impact of Undernutrition and Heart Failure on Functional and Cognitive Recovery in Hip Fracture Patients

Evidence on the effects of frailty, undernutrition, and heart failure (HF) on patients with hip fractures is scarce. This retrospective cohort study aimed to examine the effects of undernutrition and HF on outcomes in patients who underwent convalescent rehabilitation after hip fracture. Undernutrition was defined as body mass index (BMI) < 20.0 (Low BMI). Heart failure (HF) was defined as a B-type natriuretic peptide (BNP) > 100 (High BNP). The study outcomes included the Functional Independence Measure motor domain (FIM-motor) and cognitive domain (FIM-cognition) at discharge. To consider the effects of low BMI, high BNP, and the simultaneous presence of both ("low BMI and high BNP"), we used multivariate linear regression analyses to examine whether these were associated with the outcomes. A total of 110 (mean age 87.4 years, 24.8% male) were analyzed. As a result, low BMI (β = -0.088, p = 0.027) and high BNP (β = -0.053, p = 0.015), each alone, were significantly associated with the FIM motor at discharge, whereas the simultaneous presence of "low BMI and high BNP" was significantly associated with the FIM motor at discharge, while the strength of the association was greater than each association alone (β = -0.152, p = 0.010). Further, the simultaneous presence of "low BMI and high BNP" was significantly associated with FIM cognition at discharge (β = -0.109, p = 0.014). Comprehensive multidisciplinary management is needed, including preoperative or early postoperative nutritional support and rehabilitation, followed by rehabilitation nutrition care management, in patients with hip fracture.

A multidisciplinary approach to post-operative fragility hip fracture care in Thailand - a narrative review

INTRODUCTION

Appropriate care and rehabilitation following surgery for fragility hip fractures in older adults is associated with better outcomes and a greater likelihood of achieving pre-injury functioning. Clinical guidelines specifically for the post-operative care and rehabilitation of patients with hip fractures are scarce; as such, country-specific protocols benchmarked against established guidelines are essential given the wide variation in cultures and beliefs, clinical practice and diverse healthcare systems in Asia. We aimed to provide clinically relevant recommendations for post-operative fragility hip fracture care and rehabilitation to improve patient outcomes and prevent subsequent fractures in Thailand.

METHODS

A targeted literature review was conducted to identify key evidence on various elements of post-hip fracture care and rehabilitation. Further discussions at a meeting and over email correspondence led to the development of the recommendations which amalgamate available evidence with the clinical experience of the multidisciplinary expert panel.

RESULTS

Our recommendations are categorized by one period domain - acute post-operative period, and five major domains during the post-operative period - rehabilitation, optimization of bone health, prevention of falls, nutritional supplementation, and prophylaxis for venous thromboembolism. A multidisciplinary approach should be central to the rehabilitation process with the involvement of orthopedists, geriatricians/internists, physiatrists, physical and occupational therapists, endocrinologists, pharmacists and nursing staff. Other key components of our recommendations which we believe contribute to better functional outcomes in older patients undergoing hip fracture surgery include comprehensive pre-operative assessments, early surgery, goal setting for recovery and rehabilitation, early mobilization, medication optimization, tailored exercise plans, adequate coverage with analgesia, assessment and appropriate management of osteoporosis with due consideration of the fracture risk, fall prevention plans, and nutritional assessment and support. Patients and their caregivers should be a part of the recovery process at every step, and they should be counseled and educated appropriately, particularly on the importance of adherence to their rehabilitation plan.

CONCLUSION

We have provided guidance on the critical domains of clinical care in the post-operative setting to optimize patient outcomes and prevent fracture recurrence. Our recommendations for post-operative care and rehabilitation of older adults with hip fracture can serve as a framework for hospitals across Thailand.

Effect of oral nutritional supplementation on outcomes in older adults with hip fractures and factors influencing compliance

Aims

Hip fractures are a major cause of morbidity and mortality, and malnutrition is a crucial determinant of these outcomes. This meta-analysis aims to determine whether oral nutritional supplementation (ONS) improves postoperative outcomes in older patients with a hip fracture.

Methods

A systematic literature search was conducted in August 2022. ONS was defined as high protein-based diet strategies containing (or not containing) carbohydrates, fat, vitamins, and minerals. Randomized trials documenting ONS in older patients with hip fracture (aged ≥ 50 years) were included. Two reviewers evaluated study eligibility, conducted data extraction, and assessed study quality.

Results

There were 812 studies identified, of which 18 studies involving 1,522 patients met the inclusion criteria. The overall meta-analysis demonstrated that ONS was associated with significantly elevated albumin levels (weighted mean difference (WMD) 1.24 (95% confidence interval (CI) 0.95 to 1.53)), as well as a significant risk reduction in infective complications (odds ratio (OR) 0.54 (95% CI 0.39 to 0.76)), pressure ulcers (OR 0.54 (95% CI 0.33 to 0.88)), and total complications (OR 0.57 (95% CI 0.42 to 0.79)). Length of hospital stay (LOS) was also significantly reduced (WMD -2.36 (95% CI -4.14 to -0.58)), particularly in rehabilitation LOS (WMD -4.17 (95% CI -7.08 to -1.26)). There was a tendency towards a lower mortality risk (OR 0.93 (95% CI 0.62 to 1.4)) and readmission (OR 0.52 (95% CI 0.16 to 1.73)), although statistical significance was not achieved (p = 0.741 and p = 0.285, respectively). The overall compliance with ONS ranged from 64.7% to 100%, but no factors influencing compliance were identified.

Conclusion

This meta-analysis is the first to quantitatively demonstrate that ONS could nearly halve the risk of infective complications, pressure ulcers, total complications, as well as improve serum albumin and reduce LOS. ONS should be a regular and integrated part of the perioperative care of these patients, especially given that the compliance with ONS is acceptable.

Post hip fracture orthogeriatric care-a Canadian position paper addressing challenges in care and strategies to meet quality indicators

INTRODUCTION

Osteoporosis is a major disease state associated with significant morbidity, mortality, and health care costs. Less than half of the individuals sustaining a low energy hip fracture are diagnosed and treated for the underlying osteoporosis.

OBJECTIVE

A multidisciplinary Canadian hip fracture working group has developed practical recommendations to meet Canadian quality indicators in post hip fracture care.

METHODS

A comprehensive narrative review was conducted to identify and synthesize key articles on post hip fracture orthogeriatric care for each of the individual sections and develop recommendations. These recommendations are based on the best evidence available today.

CONCLUSION

Recommendations are anticipated to reduce recurrent fractures, improve mobility and healthcare outcomes post hip fracture, and reduce healthcare costs. Key messages to enhance postoperative care are also provided.

Malnutrition is associated with six-month mortality in older patients admitted to the emergency department with hip fracture

Background

Hip fractures in older people are a common health problem often associated with malnutrition that might affect outcomes. Screening for malnutrition is not a routine examination in emergency departments (ED). This analysis of the EMAAge study, a prospective, multicenter cohort study, aimed to evaluate the nutritional status of older patients (≥ 50 years) with hip fracture, factors associated with malnutrition risk, and the association between malnutrition and the six-months mortality.

Methods

Risk of malnutrition was evaluated using the Short Nutritional Assessment Questionnaire. Clinical data as well as data on depression and physical activity were determined. Mortality was captured for the first six months after the event. To assess factors associated with malnutrition risk we used a binary logistic regression. A Cox proportional hazards model was used to assess the association of malnutrition risk with six-month survival adjusted for other relevant risk factors.

Results

The sample consisted of N = 318 hip fracture patients aged 50 to 98 (68% women). The prevalence of malnutrition risk was 25.3% (n = 76) at the time of injury. There were no differences in triage categories or routine parameters measured in the ED that could point to malnutrition. 89% of the patients (n = 267) survived for six months. The mean survival time was longer in those without malnutrition risk (171.9 (167.1-176.9) days vs. 153.1 (140.0-166.2) days). The Kaplan Meier curves and the unadjusted Cox regression (Hazard Ratio (HR) 3.08 (1.61-5.91)) showed differences between patients with and patients without malnutrition risk. In the adjusted Cox regression model, risk of death was associated with malnutrition risk (HR 2.61, 1.34-5.06), older age (70-76 years: HR 2.5 (0.52-11.99); 77-82 years: HR 4.25 (1.15-15.62); 83-99 years: HR 3.82 (1.05-13.88)) and a high burden of comorbidities (Charlson Comorbidity Index ≥3: HR 5.4 (1.53-19.12)).

Conclusion

Risk of malnutrition was associated with higher mortality after hip fracture. ED parameters did not differentiate between patients with nutritional deficiencies and those without. Therefore, it is particularly important to pay attention to malnutrition in EDs to detect patients at risk of adverse outcomes and to initiate early interventions.

Influence of Nutritional Status on a Family-Centered Care Intervention for Older Adults with Cognitive Impairment following Hip-Fracture Surgery: Secondary Data Analysis of a Randomized Controlled Trial

OBJECTIVES

In Taiwan, older adults with cognitive impairment who undergo hip-fracture surgery are routinely cared for by family members. This study aimed to determine if nutritional status influenced the effects of a family-centered intervention for older adults with cognitive impairment recovering from hip-fracture surgery.

DESIGN

Secondary data analysis of data from a randomized controlled trial was conducted to examine the influences of nutritional status 1 month after hospital discharge on the effects of a family-centered care intervention model, which was designed for older adults with hip fracture and cognitive impairment. Outcomes were compared among participants according to nutrition status (well-nourished/poorly-nourished) and treatment approach (control/intervention).

SETTING

The original study was conducted at a 3000-bed medical center from July 2015 to October 2019.

PARTICIPANTS

Participants were older adults with cognitive impairment who had undergone hip-fracture surgery. Participants were assessed as poorly-nourished or well-nourished with the Mini-Nutritional Assessment (MNA) 1-month post-discharge and were then randomly assigned to either the intervention group or control group.

INTERVENTION

A family-centered intervention model for family caregivers of older adults with cognitive impairment recovering from hip-fracture surgery was implemented. The intervention was delivered by geriatric nurses, which included instructions for family caregivers in overseeing exercises for strengthening the hip, understanding dietary requirements, and managing behavioral problems associated with cognitive impairment.

MEASUREMENTS

Outcome measures included activities of daily living (ADLs), instrumental ADLs, hip range of motion, hip muscle strength, depression, measured with the Geriatric Depressive Scale, and physical and mental health related quality of life, measured with the Short Form Survey (SF-36), Taiwanese version. Participants were assessed at 1-, 3-, 6-, and 12-months post-discharge.

RESULTS

Most of the 134 participants were assessed as poorly nourished (n = 122); 57 were the control group and 65 received the intervention. For the well-nourished participants (n = 12), four were in the intervention group and eight were controls. There were no significant differences in any outcome variables for poorly nourished participants who received the intervention compared with controls. For the sample of well-nourished participants, those who received the intervention performed significantly better in outcomes of IADLs (b = 1.74, p < .05), hip muscle strength (b = 9.64, p < .01), and physical health related quality of life (b = 10.47, p < .01).

CONCLUSION

The family-centered care intervention was only effective for older adults with cognitive impairment recovering from hip-fracture surgery who were well-nourished at 1 month following hospital discharge, but not for those at risk of malnutrition. Interventions should focus on enhancing nutritional status following hip surgery which could allow the family-centered in-home intervention to be beneficial for more older adults with cognitive impairment recovering from hip-fracture surgery.
