Functional Recovery After Hip Fracture: The Combined Effects of Depressive Symptoms, Cognitive Impairment, and Delirium

Microbiota-gut-brain axis in perioperative neurocognitive and depressive disorders: Pathogenesis to treatment

An increasing number of people undergo anesthesia and surgery. Perioperative neurocognitive and depressive disorders are common central nervous system complications with similar pathogeneses. These conditions pose a deleterious threat to human health and a significant societal burden. In recent years, numerous studies have focused on the role of the gut microbiota and its metabolites in the central nervous system via the gut-brain axis. Its involvement in perioperative neurocognitive and depressive disorders has attracted considerable attention. This review aimed to elucidate the role of the gut microbiota and its metabolites in the pathogenesis of perioperative neurocognitive and depressive disorders, as well as the value of targeted interventions and treatments.

Validation of the delirium diagnostic tool-provisional (DDT-Pro) in geriatric medical inpatients with diagnostic permutations of the 3Ds with and without delirium

OBJECTIVE

Validations of brief delirium tools have not included analysis of psychiatric disorders comorbidities or control groups. We validated the Delirium Diagnostic Tool-Provisional (DDT-Pro) in 422 geriatric inpatients with high incidence of depression and/or dementia.

METHODS

Cross-sectional study using two delirium reference standards, DSM-5-TR and Delirium Rating Scale-Revised-98 (DRS-R98). We assessed concurrent and construct DDT-Pro validity too.

RESULTS

There were 117 (27.7%) delirium cases using DDT-Pro, 104 (24.6%) per DSM-5-TR and 93 (22.0%) per DRS-R98; 133 patients (31.5%) had depression and 105 (24.9%) dementia, some comorbid with delirium. DDT-Pro accuracy (AUC under ROC curve) ranges were 88.3-95.9% vs DSM-5-TR and 92.7-95.0% vs DRS-R98 for whole sample and four diagnostic groups, without statistical differences. DDT-Pro ≤6 had the most balanced sensitivity-specificity for delirium diagnosis against both DSM-5-TR and DRS-R98 with similar specificity but higher sensitivity for DRS-R98 than DSM-5-TR delirium, with the highest values in patients with depression and dementia (≥92% sensitivity, ≥81% specificity). Positive and negative likelihood ratios support diagnostic strength. Concurrent validity was high reflected by significant correlations (p < 0.001) of DDT-Pro total and item scores with DRS-R98 and Delirium Frontal Index scores, highest in groups with comorbid depression and/or dementia. The DDT-Pro represented a single construct for delirium demonstrated by one factor with high item loadings and high internal consistency reliability of its items.

CONCLUSIONS

The DDT-Pro demonstrated strong performance metrics in general hospital elderly inpatients with preexisting depression and/or dementia, which is unique among brief delirium tools. Its optimized cutoff score was the same as in other populations.

Prevalence of preoperative depression and adverse outcomes in older patients undergoing elective surgery: A systematic review and meta-analysis

STUDY OBJECTIVE

Depression is a common cause of long-lasting disability and preoperative mental health state that has important implications for optimizing recovery in the perioperative period. In older elective surgical patients, the prevalence of preoperative depression and associated adverse pre- and postoperative outcomes are unknown. This systematic review and meta-analysis aimed to determine the prevalence of preoperative depression and the associated adverse outcomes in the older surgical population.

DESIGN

Systematic review and meta-analysis.

SETTING

MEDLINE, MEDLINE Epub Ahead of Print and In-Process, In-Data-Review & Other Non-Indexed Citations, Embase/Embase Classic, Cochrane CENTRAL, and Cochrane Database of Systematic Reviews, ClinicalTrials.Gov, the WHO ICTRP (International Clinical Trials Registry Platform) for relevant articles from 2000 to present.

PATIENTS

Patients aged ≥65 years old undergoing non-cardiac elective surgery with preoperative depression assessed by tools validated in older adults. These validated tools include the Geriatric Depression Scale (GDS), Hospital Depression and Anxiety Scale (HADS), Beck Depression Inventory-II (BDI), Patient Health Questionnaire-9 (PHQ-9), and the Centre for Epidemiological Studies Depression Scale (CESD).

INTERVENTIONS

Preoperative assessment.

MEASUREMENT

The primary outcome was the prevalence of preoperative depression. Additional outcomes included preoperative cognitive impairment, and postoperative outcomes such as delirium, functional decline, discharge disposition, readmission, length of stay, and postoperative complications.

MAIN RESULTS

Thirteen studies (n = 2824) were included. Preoperative depression was most assessed using the Geriatric Depression Scale-15 (GDS-15) (n = 12). The overall prevalence of preoperative depression was 23% (95% CI: 15%, 30%). Within non-cancer non-cardiac mixed surgery, the pooled prevalence was 19% (95% CI: 11%, 27%). The prevalence in orthopedic surgery was 17% (95% CI: 9%, 24%). In spine surgery, the prevalence was higher at 46% (95% CI: 28%, 64%). Meta-analysis showed that preoperative depression was associated with a two-fold increased risk of postoperative delirium than those without depression (32% vs 23%, OR: 2.25; 95% CI: 1.67, 3.03; I2: 0%; P ≤0.00001).

CONCLUSIONS

The overall prevalence of older surgical patients who suffered from depression was 23%. Preoperative depression was associated with a two-fold higher risk of postoperative delirium. Further work is needed to determine the need for depression screening and treatment preoperatively.

DRGKB: a knowledgebase of worldwide diagnosis-related groups' practices for comparison, evaluation and knowledge-guided application

As a prospective payment method, diagnosis-related groups (DRGs)'s implementation has varying effects on different regions and adopt different case classification systems. Our goal is to build a structured public online knowledgebase describing the worldwide practice of DRGs, which includes systematic indicators for DRGs' performance assessment. Therefore, we manually collected the qualified literature from PUBMED and constructed DRGKB website. We divided the evaluation indicators into four categories, including (i) medical service quality; (ii) medical service efficiency; (iii) profitability and sustainability; (iv) case grouping ability. Then we carried out descriptive analysis and comprehensive scoring on outcome measurements performance, improvement strategy and specialty performance. At last, the DRGKB finally contains 297 entries. It was found that DRGs generally have a considerable impact on hospital operations, including average length of stay, medical quality and use of medical resources. At the same time, the current DRGs also have many deficiencies, including insufficient reimbursement rates and the ability to classify complex cases. We analyzed these underperforming parts by domain. In conclusion, this research innovatively constructed a knowledgebase to quantify the practice effects of DRGs, analyzed and visualized the development trends and area performance from a comprehensive perspective. This study provides a data-driven research paradigm for following DRGs-related work along with a proposed DRGs evolution model.

The role of depression in the association between mobilisation timing and live discharge after hip fracture surgery: Secondary analysis of the UK National Hip Fracture Database

PURPOSE

The aim was to compare the probability of discharge after hip fracture surgery conditional on being alive and in hospital between patients mobilised within and beyond 36-hours of surgery across groups defined by depression.

METHODS

Data were taken from the National Hip Fracture Database and included patients 60 years of age or older who underwent hip fracture surgery in England and Wales between 2014 and 2016. The conditional probability of postsurgical live discharge was estimated for patients mobilised early and for patients mobilised late across groups with and without depression. The association between mobilisation timing and the conditional probability of live discharge were also estimated separately through adjusted generalized linear models.

RESULTS

Data were analysed for 116,274 patients. A diagnosis of depression was present in 8.31% patients. In those with depression, 7,412 (76.7%) patients mobilised early. In those without depression, 84,085 (78.9%) patients mobilised early. By day 30 after surgery, the adjusted odds ratio of discharge among those who mobilised early compared to late was 1.79 (95% CI: 1.56-2.05, p<0.001) and 1.92 (95% CI: 1.84-2.00, p<0.001) for those with and without depression, respectively.

CONCLUSION

A similar proportion of patients with depression mobilised early after hip fracture surgery when compared to those without a diagnosis of depression. The association between mobilisation timing and time to live discharge was observed for patients with and without depression.

Investigation of Factors Related to the Week 1 Cumulated Ambulation Score in Patients With Proximal Femoral Fractures Post-surgery Using Decision Tree Analysis

This study aimed to identify factors associated with the Cumulated Ambulation Score (CAS) in the first week post-surgery (Week 1 CAS) in patients with proximal femoral fractures. Proximal femoral fractures are prevalent in the elderly, with rising incidence rates and significant social and functional implications. The ability to walk postoperatively is a critical determinant of patient prognosis. The study included 53 patients out of 79 who underwent surgery for proximal femoral fractures at the orthopedics department of Oita Oka Hospital from January 2021 to December 2021. Exclusion criteria were pre-existing walking difficulties, inability to be evaluated in the first postoperative week, non-weight bearing post-surgery, and complications during hospitalization. The physical therapy program followed Oita Oka Hospital's clinical path, starting ambulation with a walker within the first week post-surgery. Data collected included patient background, surgical techniques, pre-injury ambulatory status, and pre-admission residential environment. Physical function assessments one week postoperatively included range of motion (ROM), manual muscle testing (MMT), pain evaluation (NRS), and CAS. Statistical analyses involved the Shapiro-Wilk test, independent t-test, Mann-Whitney U test, chi-square test, and decision tree analysis using classification and regression trees (CART). Patients were categorized into 'favorable' and 'poor' groups based on Week 1 CAS. Significant differences in dementia presence and pre-admission living environment were noted between groups. Knee extension MMT at Week 1 postoperatively showed a significant difference. The decision tree analysis identified knee extension MMT as the primary variable, with a threshold of 3.5. In patients with MMT below 3.5, dementia presence was a secondary factor, with 81% in the poor CAS group. In patients with MMT above 3.5, knee extension strength continued to be significant. The model's accuracy was 64%, with precision at 71%, recall at 63%, and an F1-score of 0.67. The study highlights knee extension MMT and dementia presence as significant factors influencing Week 1 CAS in patients with proximal femoral fractures. The poor CAS group had a higher proportion of dementia and weaker knee extension MMT. Dementia hinders rehabilitation effectiveness, impacting recovery in knee extension strength and CAS. The decision tree analysis provided an intuitive understanding of variable interrelationships, emphasizing knee extension strength as the primary factor, followed by dementia in cases with lower MMT scores. This study elucidated factors related to Week 1 CAS in postoperative patients with proximal femoral fractures. Knee extension MMT emerged as the initial factor, followed by the presence of dementia, influencing Week 1 CAS. These findings are crucial for rehabilitation planning and long-term prognostic predictions in this patient population. However, the study's limitations include potential selection bias and a small sample size, necessitating further research for enhanced predictive accuracy.

New onset postoperative depression after major surgery: an analysis from a national claims database

Background

Postoperative depression is not well characterised. We investigated the incidence of postoperative depression with the hypothesis that after controlling for confounders, new onset depression would vary significantly by surgical type.

Methods

We conducted a retrospective cohort study using the Optum Clinformatics Datamart. The primary outcome was new onset postoperative depression, defined by a new diagnosis of depression or new prescription for an antidepressant in the year after surgery using International Classification of Diseases (ICD) 9/10 codes and drug names. Adjustment for preoperative comorbidities and predictors of depression was with multivariable Cox regression and propensity score matching. Sensitivity analyses defining new onset depression as both a new diagnosis of depression and a new prescription for an antidepressant, or either outcome separately, were conducted.

Results

Data from 132 390 cardiac surgery, 12 538 thoracotomy, 32 630 video-assisted thoracoscopic surgery (VATS), 96 750 hip fracture surgery, 157 484 hip replacement, and 347 878 laparoscopic cholecystectomy patients from January 2004 to June 2021 were analysed. The incidence of new onset postoperative depression was 18.8% for hip fracture surgery, 16.1% for thoracotomy, 12.6% for cardiac surgery, 12.4% for VATS, 8.6% for laparoscopic cholecystectomy, and 6.8% for hip replacement. After multivariable adjustment, hip fracture surgery patients were most likely to develop new onset postoperative depression (hazard ratio [95% confidence interval]) 1.56 [1.45-1.68]), followed by thoracotomy (1.12 [1.03-1.22]), cardiac surgery (1.09 [1.04-1.12]), VATS (0.95 [0.90-1.00]), and hip replacement (0.55 [0.52-0.57]) compared with patients undergoing laparoscopic cholecystectomy (hazard ratio=1). Results from propensity score matched analyses and sensitivity analyses were similar.

Conclusions

The risk of postoperative depression differs by surgical type after controlling for preoperative characteristics.

Associations between depression symptom burden and delirium risk: a prospective cohort study

BACKGROUND AND OBJECTIVES

Delirium and depression are increasingly common in aging. There is considerable clinical overlap, including shared symptoms and comorbid conditions, including Alzheimer's disease (AD), functional decline, and mortality. Despite this, the long-term relationship between depression and delirium remains unclear. This study assessed the associations of depression symptom burden and its trajectory with delirium risk in a 12-year prospective study of older individuals during hospitalization.

RESEARCH DESIGN AND METHODS

319,141 UK biobank participants between 2006-2010 (mean 58y [range 37-74, SD=8], 54% female) reported frequency (0-3) of four depressive symptoms (mood, disinterest, tenseness, or lethargy) in the preceding 2 weeks, and aggregated into a depressive symptom burden score (0-12). New-onset delirium was obtained from hospitalization records during 12y median follow-up. 40,451 (mean age 57±8; range 40-74y) had repeat assessment on average 8y after their first. Cox proportional hazard models examined whether depression symptom burden and trajectory predicted incident delirium during hospitalization.

RESULTS

5,753 (15 per 1000) newly developed delirium during follow-up. Increased risk for delirium was seen for mild (aggregated scores 1-2, hazards ratio, HR=1.16, [95% confidence interval 1.08-1.25], p<0.001), modest (scores 3-5, 1.30 [1.19-1.43], p<0.001) and severe (scores ≥ 5, 1.38 [1.24-1.55], p<0.001) depressive symptoms, versus none in the fully adjusted model. These findings were independent of the number of hospitalizations and consistent across hospitalization settings (e.g., surgical, medical, or critical care) and specialty (e.g., neuropsychiatric, cardiorespiratory or other). Worsening depression symptoms (≥1 point increase), compared to no change/improved score, were associated with an additional 39% increased risk (1.39 [1.03-1.88], p=0.03) independent of baseline depression burden. The association was strongest in those over 65y at baseline (p for interaction <0.001).

DISCUSSION AND IMPLICATIONS

Depression symptom burden and worsening trajectory predicted delirium risk during hospitalization. Increased awareness of subclinical depression symptoms may be warranted for delirium prevention.

Practical Application of a Battery of Brief Tools to Evaluate Geriatric Medical Inpatients for the Three Ds

OBJECTIVE

The investigators aimed to identify the clinical characteristics of patients with or without delirium and preexisting depression, dementia, both, or neither by using validated tools easily administered in clinical practice.

METHODS

In this cross-sectional prospective observational study conducted in Medellín, Colombia, 200 geriatric inpatients were evaluated with the Delirium Diagnostic Tool-Provisional (DDT-Pro), Informant Questionnaire on Cognitive Decline in the Elderly, Hachinski Ischemic Scale, Cornell Scale for Depression in Dementia, and Charlson Comorbidity Index-short form. Delirium motor subtype, mortality, and length of hospital stay were assessed.

RESULTS

The study included 134 patients without delirium (67%), 14 with delirium only (7%), 16 with delirium and dementia (8%), 13 with delirium and depression (7%), and 23 with delirium, dementia, and depression (the three Ds) (12%). Prevalence rates of dementia (59%) and depression (55%) among 66 patients with delirium were higher than prevalence rates among patients without delirium (13% and 28%, respectively), suggesting that both conditions are risk factors. Main medical diagnoses, mortality, and dementia type did not differ among groups. Motor subtypes were similar among delirium groups. Patients in the delirium groups, except those in the delirium and depression group, were older than patients without delirium. Medical burden was highest among the patients with delirium and dementia and those with all three conditions. Delirium and dementia were more severe when comorbid with each other. Depression was most severe among patients with delirium and depression. Patients with all three conditions had a longer length of hospital stay than those without delirium.

CONCLUSIONS

Using brief tools to detect dementia and depression in conjunction with the DDT-Pro to assess delirium diagnosis and severity is feasible and enables a more in-depth evaluation of elderly hospitalized patients. Because previous longitudinal research suggests that these comorbid conditions influence prognosis following a delirium episode, better identification of the three Ds offers proactive interventional opportunities. Depression is an underrecognized risk factor for delirium.

Effects of depressive symptoms on osteoporotic bone metabolism and prognosis of joint replacement surgery in elderly male patients with femoral neck fracture

OBJECTIVE

To investigate the effect of depressive symptoms on osteoporotic bone metabolism and prognosis of joint replacement surgery in elderly male patients with femoral neck fractures.

METHOD

102 elderly male patients with femoral neck fractures hospitalized in the Beijing Hospital from January 2017 to January 2019 were included. The patients with femoral neck fractures were divided into the depression group and the control group. The observation indicators included: bone mineral density, serum alkaline phosphatase, serum calcium, serum phosphorus, 25-hydroxy-vitamin D, osteocalcin, Type I procollagen amino-terminal propeptide, serum β-isomer of C-terminal telopeptide of type I collagen, hip function scores, and pain visual analogue scale at pre- and post-operative examinations.

RESULTS

The BMD was significantly lower in the depressed group than in the control group [either for lumbar spine or hip, P < 0.05]. Serum 25-(OH)-D levels and serum OC levels were lower (both P < 0.05) in the depression group, while serum -CTX levels were higher in the depression group than in the control group (P < 0.05). Depression severity (GDS score) was negatively correlated with BMD (r = -0.456, P < 0.05), 25(OH)D (r = -0.546, P < 0.05), and OC (r = -0.215, P < 0.05), while positively correlated with β-CTX (r = 0.372, P < 0.05). The Harris scores of the depression group were lower than the control group (P < 0.001). In the control group, VAS scores decrease at 12 months postoperatively while in the depressed group, VAS scores increased (P < 0.001).

CONCLUSION

Depression is a risk factor for low bone mineral density and fracture, and adversely affects functional recovery and pain relief after artificial femoral head replacement. Special care should be taken for those patients with depressive symptoms in orthopedic practice.

Postoperative delirium is a risk factor of institutionalization after hip fracture: an observational cohort study

Introduction

Hip fracture is a common clinical problem in geriatric patients often associated with poor postoperative outcomes. Postoperative delirium (POD) and postoperative neurocognitive disorders (NCDs) are particularly frequent. The consequences of these disorders on postoperative recovery and autonomy are not fully described. The aim of this study was to determine the role of POD and NCDs on the need for institutionalization at 3 months after hip fracture surgery.

Method

A population-based prospective cohort study was conducted on hip fracture patients between March 2016 and March 2018. The baseline interview, which included a Mini-Mental State Examination (MMSE), was conducted in the hospital after admission for hip fracture. NCDs were appreciated by MMSE scoring evolution (difference between preoperative MMSE and MMSE at day 5 >2 points). POD was evaluated using the Confusion Assessment Method. The primary endpoint was the rate of new institutionalization at 3 months. We used a multivariate analysis to assess the risk of new institutionalization.

Results

A total of 63 patients were included. Thirteen patients (20.6%) were newly institutionalized at 3 months. Two factors were significantly associated with the risk of postoperative institutionalization at 3 months: POD (OR = 5.23; 95% CI 1.1-27.04; p = 0.04) and IADL evolution (OR = 1.8; 95% CI 1.23-2.74; p = 0.003).

Conclusion

Only POD but not NCDs was associated with the risk of dependency and institutionalization after hip fracture surgery. The prevention of POD appears to be essential for improving patient outcomes and optimizing the potential for returning home.

Factors predictive of functional outcomes and quality of life in patients with fragility hip fracture: A retrospective cohort study

To determine the predictors of functional outcomes and quality of life (QoL) of patients who were surgically treated for fragility hip fracture. This was a retrospective cohort study performed in the 3 tertiary rehabilitation facilities. A total of 165 patients who had undergone surgery for fragility hip fracture were followed up to 6 months postoperatively. The factors expected to be related to the functional outcomes and QoL at 6 months post-surgery were as follows: baseline demographics, fracture site, operation type, fall characteristics including fall location and fall direction, comorbidities, and initial functional status. The following were comorbidities: hypertension, diabetes mellitus, dementia, cerebrovascular accident, and osteoporosis. Functional outcome and QoL measures were represented using the Koval grade, functional ambulatory category (FAC), Berg balance scale, 4-m walking speed test, the Korean version of Mini-Mental State Examination, EuroQol 5-dimension (EQ-5D) questionnaire, the Korean version of Modified Barthel Index, and the Korean version of instrumental activities of daily living (K-IADL). For all tests, each patient was assessed immediately after transfer and at 6 months post-surgery. Multivariable regression analyses adjusting for factors mentioned above were as follows. Old age led to a significantly less favorable outcome on FAC and K-IADL at 6 months. Intertrochanteric fracture had a significantly positive impact on Koval at 6 months compared to femur neck and intertrochanteric fractures. Total hip replacement arthroplasty and bipolar hemiarthroplasty had a significantly positive impact on EQ-5D and FAC at 6 months respectively compared to other operation types. Fall characteristics didn't reveal any significant impact on functional outcomes and QoL. Patients with hypertension and diabetes mellitus had a significantly negative outcome on EQ-5D and K-IADL respectively. Among initial assessments of function and QoL, initial 4-m walking speed test, Korean version of Mini-Mental State Examination, K-IADL, and Korean version of Modified Barthel Index were independent predictors of function and QoL at 6 months. This study confirmed that age, fracture site, operation type, comorbidities, and initial physical and cognitive function significantly influenced recovery of function and QoL at 6 months in patients with fragility hip fractures.

Implementing an intervention to enhance care delivery and consistency for people with hip fracture and cognitive impairment in acute hospital wards: a mixed methods process evaluation of a randomised controlled feasibility trial (PERFECTED)

OBJECTIVES

To determine how, and under what circumstances, the PERFECT-ER intervention was implemented in five acute hospital wards and impacted on staff practices and perceptions.

DESIGN

Mixed methods process evaluation (undertaken between 2016 and 2018).

SETTING

Five acute hospital wards across three different UK regions.

PARTICIPANTS

Patients (n=3) admitted to acute wards with hip fracture and cognitive impairment, their relatives (n=29) and hospital staff (n=63).

INTERVENTIONS

PERFECT-ER, a multicomponent intervention designed to enhance the recovery of patients with hip fracture and cognitive impairment was implemented for 18 months. PERFECT-ER was implemented at ward level ensuring that multiple new and existing practices were undertaken consistently, on the assumption that collectively, small individual advances would improve care delivery for patients.

PRIMARY AND SECONDARY OUTCOME MEASURES

Implementation of the PERFECT-ER intervention examined through regular intervention scores, service improvement staff reports and action plans, and semi-structured interviews and focus groups.

RESULTS

The process evaluation identified points of implementation vulnerability and strength. All wards implemented some elements of PERFECT-ER. Implementation was fragile when ward pressures were high and when ward staff perceived the relative priority of intervention practices to be low. Adaptations to the implementation process may have reduced whole-ward staff engagement with implementation. However, strategical enlistment of senior ward influencers (such as ward managers, orthogeriatricians) combined with service improvement lead in-ward peer pressure tactics facilitated implementation processes.

CONCLUSIONS

Our study suggests that implementation was expediated when senior staff were on board as opinion leaders and formally appointed internal implementation leaders exerted their power. Within hierarchical settings such as acute wards, key individuals appeared to influence implementation through endorsement and sometimes enforcement. This indicates that whole-ward interventions may not always require cognitive engagement from all ward staff to implement changes. Future ward-level implementation studies could consider how best to engage staff and most importantly, which staff to best target.

Prevalence and prognostic significance of depressive symptoms in a geriatric post-hip fracture assessment

OBJECTIVES

To investigate the prevalence and prognostic significance of post-hip fracture depressive symptoms.

METHODS

A naturalistic clinical cohort study. Data were collected on admission to hospital, geriatric assessment 4-6 months post-fracture and by telephone interview one-year post fracture. Depressive symptoms were assessed at the geriatric assessment using the 15-item Geriatric Depression Scale (GDS-15). Logistic regression analyses with multivariable models were conducted to examine the association of depressive symptoms with changes in mobility and living arrangements and Cox proportional hazards models for mortality between the geriatric assessment and one-year follow-up.

RESULTS

Of the 1070 patients, 22% (n = 238) had mild and 6% (n = 67) moderate to severe depressive symptoms. Patients with depressive symptoms had poorer nutritional status at baseline, lower scores on the cognitive and physical performance tests and poorer functional abilities in the geriatric assessment than those without. No association was observed between depressive symptoms and any of the outcomes at one-year follow-up. Poor nutritional status and physical functioning remained significant prognostic indicators.

CONCLUSION

Post-hip fracture depressive symptoms are common and deserve attention during post-hip fracture recovery and rehabilitation. Nonetheless, depressive symptoms have no impact on the change in mobility or living arrangements or mortality. These latter outcomes are mainly explained by poor nutritional status and functioning.

Epidemiology of delirium in hospitalized patients in Latin America: A systematic review

BACKGROUND

Accurate epidemiological data are essential for the planning of policies aimed at the identification, prevention, and management of delirium. The reported occurrence of delirium in hospitalized patients varies widely among studies, ranging between 5% to more than 80% in the international literature. The exact occurrence in Latin America is not well described.

OBJECTIVE

The aim of this study is to conduct a systematic analysis of the published data on the epidemiology of delirium in hospitalized patients in Latin America.

METHODS

We conducted a systematic review following PRISMA guidelines. Both MEDLINE and LILACS databases were searched for original research articles reporting the occurrence of delirium among adult hospitalized patients in Latin American countries. Studies including pediatric populations were excluded from this analysis. Two authors independently applied eligibility criteria, assessed quality, and extracted data. The corresponding authors of the original articles were contacted to obtain relevant information about the study when this was not present in the published manuscripts.

RESULTS

Seven hundred and eighteen original articles were identified. After screening titles and abstracts, 149 studies were included in the final analysis. The occurrence of delirium varied depending on the clinical scenario: (1) in the general medico-surgical wards, it ranged from 2.1% to 60.4%, (2) in the Intensive Care Units (ICUs), from 9.6% to 94.8%, (3) in the post-operatory population, from 5.45% and 52.3%, and (4) it was found to be between 10.7% and 62% in the emergency department setting. The most used delirium assessment tools were the "Confusion Assessment Method" (CAM; in the general population), and the "Confusion Assessment Method for the ICU" (CAM-ICU). Fourteen out of 149 studies were conducted in clinical settings who actively implemented some form of non-pharmacological delirium prevention bundles, most of them as part of ICU sedation-analgesia protocols.

CONCLUSION

Delirium occurs frequently in hospitalized patients in Latin America throughout a variety of clinical scenarios, including ICU, general wards, post-operatory populations, and among the emergency department setting. The CAM and the CAM-ICU are the most used delirium assessment tools. Bundles of non-pharmacological interventions to prevent delirium are not universally implemented.

Low geriatric nutritional risk index is a risk factor for death within 1 year following hip fracture

PURPOSE

Hip fracture is common in older patients and is associated with high mortality and functional impairment. The Geriatric Nutritional Risk Index (GNRI) evaluates the risk of malnutrition-related complications, and the Barthel Index (BI) evaluates older patients' functional status. The study aim was to determine the risk factors for both death and decreased BI within 1 year after hip fracture.

METHODS

We retrospectively reviewed the records of 108 patients who were treated for hip fractures in 10 public or private hospitals from February to July 2007. Participating facilities comprised eight public or private hospitals with 200-499 beds, and two private or orthopedic hospitals with 20-199 beds. We evaluated several risk factors for death and lower BI within 1 year after hip fracture.

RESULTS

The mortality rate within 1 year postoperatively for patients who survived inpatient stay was 6.5% (7/108). The proportion of patients with decreased postoperative BI was 43.6% (44/101). Binomial logistic regression analysis showed that several factors, including low GNRI (odds ratio [OR]: 0.80; 95% confidence interval [CI: 0.68-0.93]), were risk factors for death within 1 year. Postoperative delirium (OR: 8.84 [1.52-51.6]), postinjury dementia (OR: 34.8 [3.01-402]), preinjury BI (OR: 1.05 [1.02-1.08]), and preinjury dementia (OR: 6.22 [1.73-22.4]) were risk factors for decreased postoperative BI.

CONCLUSIONS

Our findings indicated that lower GNRI was a risk factor for death within 1 year of hip surgery and that delirium and dementia were among the risk factors for decreased BI 1 year after hip fracture.

Predictors of Moderate or Severe Cognitive Impairment at Six Months of the Hip Fracture in the Surgical Patient over 65 Years of Age

Background: cognitive impairment is known to be very common in patients with hip fractures, but studies are needed to help understand the relationship between both events. Our goal was to determine the relationship between moderate or severe cognitive impairment and hip fractures during the six months following that episode. Methods: a retrospective longitudinal study was conducted on a sample of 665 people over 65 years of age. The main variable of the study was cognitive impairment at six months of fracture, assessed using the Pfeiffer scale (PS). Other data related to clinical features were also collected for further analysis. Results: binary logistic regression analyses showed that the main factors related to moderate or severe cognitive impairment at the sixth month of the fracture were age (OR = 1.078), initial cognitive impairment (OR = 535.762), and discharge (OR = 547.91), cognitive worsening at the sixth month with respect to the time of admission (OR = 7.024), moderate dependence on admission (OR = 15.474) and at six months (OR = 8.088), poor ambulation at discharge (OR = 5.071) and institutionalization prior to admission (OR = 5.349) or during the first semester after fracture (OR = 6.317). Conclusions: this research provides evidence about the clinical factors that predict moderate or severe cognitive decline at the sixth month in patients undergoing surgery for a hip fracture.

Impact of orthogeriatric care management by orthopedic surgeons and physicians on in-hospital clinical outcomes: A difference-in-difference analysis

AIM

The orthopedic surgery unit in our suburb serves a large elderly trauma population in addition to providing elective surgeries. As patients with hip fractures have become older and at higher risk of medical complications, our hospital has initiated integrated co-management of these patients by orthopedic surgeons and geriatricians from the point of hospital admission. The aim of this study was to evaluate the impact of the hospital policy change on hip fracture management and clinical outcome indicators.

METHODS

Using the difference-in-difference approach, in total, 288 consecutive patients with hip fractures treated during the 1 year before and 2 years after transition to orthogeriatric care from a geriatric consultation model to integrated orthogeriatric care model were compared with 576 patients from other local hospitals.

RESULTS

Despite a seasonal trend toward increased length of hospital stay in winter, the intervention significantly reduced the change in mean length of stay (mean difference [95% confidence interval], -12.9 days [-21.5 to -4.3]; P = 0.007) and discharge to home tended to change less frequently (-12.6%; P = 0.10). There was no significant reduction in mean time to surgery (-0.2 days; P = 0.83), mortality (-0.8%; P = 0.62), or complications (-1.0%; P = 0.85).

CONCLUSIONS

Changing our hip fracture service from a geriatric consultation model of care to an integrated orthogeriatric model significantly reduced length of hospital stay probably due to a lower chance of discharge to home. To our knowledge, this is the first study in Japan to compare two orthogeriatric care models considering the nationwide improvement in hip fracture management.

Discharge after hip fracture surgery in relation to mobilisation timing by patient characteristics: linked secondary analysis of the UK National Hip Fracture Database

Background

Early mobilisation leads to a two-fold increase in the adjusted odds of discharge by 30-days compared to late mobilisation. Whether this association varies by patient characteristics identified as reasons for delayed mobilisation is unknown.

Methods

Audit data was linked to hospitalisation records for 133,319 patients 60 years or older surgically treated for hip fracture in England or Wales between 2014 and 2016. Adjusted proportional odds regression models tested whether the cumulative incidences of discharge differed between those mobilised early and those mobilised late for subgroups defined by dementia, delirium, hypotension, prefracture ambulation, and prefracture residence, accounting for the competing risk of death.

Results

Overall, 34,253 patients presented with dementia, 9818 with delirium, and 10,123 with hypotension. Prefracture, 100,983 were ambulant outdoors, 30,834 were ambulant indoors only, 107,144 were admitted from home, and 23,588 from residential care. 1502 had incomplete data for ambulation and 2587 for prefracture residence. 10, 8, 8, 12, and 12% fewer patients with dementia, delirium, hypotension, ambulant indoors only prefracture, or admitted from residential care mobilised early when compared to those who presented without dementia, delirium, hypotension, with outdoor ambulation prefracture, or admitted from home. The adjusted odds ratios of discharge by 30-days postoperatively among those who mobilised early compared with those who mobilised late were 1.71 (95% CI 1.62–1.81) for those with dementia, 2.06 (95% CI 1.98–2.15) without dementia, 1.56 (95% CI 1.41–1.73) with delirium, 2.00 (95% CI 1.93–2.07) without delirium, 1.83 (95% CI, 1.66–2.02) with hypotension, 1.95 (95% CI, 1.89–2.02) without hypotension, 2.00 (95% CI 1.92–2.08) with outdoor ambulation prefracture, 1.80 (95% CI 1.70–1.91) with indoor ambulation only prefracture, 2.30 (95% CI 2.19–2.41) admitted from home, and 1.64 (95% CI 1.51–1.77) admitted from residential care, accounting for the competing risk of death.

Conclusion

Irrespective of dementia, delirium, hypotension, prefracture ambulation or residence, early compared to late mobilisation increased the likelihood of hospital discharge by 30-days postoperatively. However, fewer patients with dementia, delirium, or hypotension, poorer prefracture ambulation, or from residential care mobilised early. There is a need reduce this care gap by ensuring sufficient resource to enable all patients to benefit from early mobilisation.

Physical interventions for people with more advanced dementia - a scoping review

BACKGROUND

Dementia is a neuro-degenerative condition resulting in cognitive and physical decline over time. In the early stages of the condition, physical decline may be slow, but in the later stages, it may become more pronounced. Physical interventions may be employed to try and reduce the physical decline that people experience, yet it is unclear what interventions may be effective. The aim of this study was to explore the breadth and quantity of evidence that exists in relation to the delivery of physical interventions for people with advanced dementia.

METHODS

We undertook a scoping review in order to map the current literature. All types of study design were included in the search in order to gain a comprehensive scope of the literature. We searched a variety of databases from inception until March 2021, focusing on physical interventions. Double screening and data extraction were employed in order to increase the reliability of the results.

RESULTS

Our review found four studies which focused on physical interventions aimed at improving physical outcomes for people with more advanced dementia. The majority of studies were excluded as their interventions were not specific to people with advanced dementia. The studies that were included incorporated functional activities and, despite small sample sizes, suggested statistically significant improvements in outcomes for people with advanced dementia.

CONCLUSION

There is currently limited evidence relating to physical rehabilitation interventions for people with more advanced dementia, however, the evidence we presented suggests potential benefits for physical outcomes. Future research should focus on robust research to determine the most effective and cost-effective interventions that meet the needs of this population.

Early recovery of basic mobility under femoral nerve block after hip fracture surgery - A propensity score matched pilot study

BACKGROUND

Previous studies have shown better pain reduction utilizing femoral nerve block (FNB) in patients who underwent hip fracture surgery. However, few studies have focused on the recovery of physical function after FNB, and most studies excluded patients with dementia. We investigated the association between FNB performed in the operating room and the recovery of physical function after hip fracture surgery, including patients with dementia.

METHODS

A total of 103 patients with a mean age of 87.4 years who underwent hip fracture surgery under spinal anesthesia between July 2015 and December 2017 (46 patients receiving a single injection of FNB and 57 standard care) were enrolled. Patients with FNB versus standard care were matched by a propensity score to adjust for patient characteristics. An anesthesiologist performed FNB with 20ml of 0.2% ropivacaine, and the standard care group received intravenous 1000 mg acetaminophen or 50mg flurbiprofen once after surgery. After matching, 78 patients were analyzed. Our primary outcome was 3-day cumulated ambulation score (CAS, 0-18 points) and secondary outcomes were 1-day CAS on postoperative day 1-3 and length of hospital stay. We also stratified patient groups based on the presence of dementia and fracture type.

RESULTS

Patients undergoing FNB had significantly better 3-day CAS compared to standard care (mean [SD], 8.72 [3.42] vs 7.33 [2.62]; mean difference, 1.38 [95%CI; 0.03 - 2.74]; p = 0.048) and 1-day CAS on postoperative day two (mean [SD], 3.10 [1.39] vs 2.56 [0.94]; mean difference, 0.54 [0.01 - 1.07]; p = 0.049). Length of hospital stay did not significantly differ among the two groups (p = 0.65). Larger positive effect was likely to be seen for patients with a femoral neck fractures and for those without dementia.

CONCLUSIONS

Patients who underwent surgery with spinal anesthesia plus FNB had better ambulatory status early after hip fracture surgery compared to patients not offered FNB. The beneficial association between FNB and ambulatory status was likely to be observed especially in patients with femoral neck fracture and without dementia.

Sex Differences in Recovery Across Multiple Domains Among Older Adults With Hip Fracture

BACKGROUND

Hip fractures are a public health problem among older adults, but most research on recovery after hip fracture has been limited to females. With growing numbers of hip fractures among males, it is important to determine how recovery outcomes may differ between the sexes.

METHODS

168 males and 171 females were enrolled within 15 days of hospitalization with follow-up visits at 2, 6, and 12 months postadmission to assess changes in disability, physical performance, cognition, depressive symptoms, body composition, and strength, and all-cause mortality. Generalized estimating equations examined whether males and females followed identical outcome recovery assessed by the change in each outcome.

RESULTS

The mean age at fracture was similar for males (80.4) and females (81.4), and males had more comorbidities (2.5 vs 1.6) than females. Males were significantly more likely to die over 12 months (hazard ratio 2.89, 95% confidence interval: 1.56-5.34). Changes in outcomes were significantly different between males and females for disability, gait speed, and depressive symptoms (p < .05). Both sexes improved from baseline to 6 months for these measures, but only males continued to improve between 6 and 12 months. There were baseline differences for most body composition measures and strength; however, there were no significant differences in change by sex.

CONCLUSIONS

Findings confirm that males have higher mortality but suggest that male survivors have continued functional recovery over the 12 months compared to females. Research is needed to determine the underlying causes of these sex differences for developing future prognostic information and rehabilitative interventions.

Evaluation of a new screening instrument for psychological distress in postacute rehabilitation in older person

PURPOSE

Although psychological distress has a negative impact on functional recovery, institutionalisation and mortality rates, there is typically no established procedure to screen for psychological distress in geriatric rehabilitation. The aim of the study was to evaluate a brief single-item Verbal Numerical Rating Scale (VNRS-PD) as a screening tool for psychological distress in multimorbid geriatric rehabilitation patients.

METHODS

In this cross-sectional study, N = 132 geriatric rehabilitation in-patients (M = 82 years old; 70.5% female) completed a verbal numerical rating scale (VNRS-PD) on satisfaction with their mood as well as the Hospital Anxiety and Depression Scale (HADS) and the short-form of the Geriatric Depression Scale (GDS). Based on the questionnaire data, the rehabilitation patients were classified as high or low in psychopathology. Using receiver-operating characteristic (ROC) curve analysis, optimal cutoff scores of the VNRS-PD were calculated for each questionnaire to detect significant psychological distress.

RESULTS

Between 28.8% (HADS ≥ 18) and 43.9% (GDS ≥ 6) of the sample had above-cutoff questionnaire scores. The area under the curve (AUC) of the VNRS-PD varied from 0.785 (95%-CI 0.709-0.861) (GDS ≥ 6) and 0.790 (95%-CI 0.716-0.864) (HADS ≥ 18) to 0.807 (95%-CI 0.734-0.880) (GDS ≥ 7). A score of ≤ 5 in the VNRS-PD proved to be the cutoff with an optimal trade-off between sensitivity (0.776-0.867) and specificity (0.638-0.703).

CONCLUSION

The VNRS-PD may be a suitable screening instrument to detect patients with psychological distress in inpatient geriatric rehabilitation for and to initiate further diagnostics within a graduated psychodiagnostic scheme. This first step may help to identify older patients with psychological distress and mental disorders, to initiate targeted interventions. Further research is needed to replicate these findings in a larger sample.

Effect of Dementia on Outcomes After Surgically Treated Hip Fracture in Older Adults

BACKGROUND

Hip fractures are associated with increased mortality and functional limitations. However, the effect that dementia has on these outcomes in individuals in aged care settings after fracture is not well established. This study examined the association of dementia with post-hip fracture mortality, permanent residential aged care entry, transition care use, and change in activities of daily living (ADL) needs.

METHODS

A retrospective cohort study using data from the Registry of Senior Australians (2003-2015) was conducted. Individuals with a hip fracture while receiving aged care services were included. Associations of dementia with mortality, risks of transition and permanent care use, and ADL needs progression were estimated using multivariable Cox, Fine-Gray, and logistic regression methods, respectively.

RESULTS

Of 4771 individuals evaluated, 76% were women, the median age was 86 years (IQR 82-90), and 71% already lived in permanent residential aged care at the time of fracture. Within two years of their hip fracture, 50.4% (95% CI 48.9%-51.8%) of individuals died, 16.2% (95% CI 14.2%-18.2%) entered a transition care program, 59.1% (95% CI 56.5%-61.7%) entered permanent residential aged care, and 32% had greater ADL needs. Dementia was associated with higher risk of two-year mortality (HR = 1.19, 95% CI 1.09-1.30), 90-day entry into permanent care (sHR = 1.96, 95% CI 1.60-2.38), and increased likelihood of ADL limitations (OR = 1.36, 95% CI 1.00-1.85). Minor differences were seen in transition care use by dementia status.

CONCLUSION

Dementia is a strong risk factor for mortality after hip fractures in individuals in aged care settings and associated with a high risk of entry into permanent care.

Factors Associated with Recovered Functionality After Hip Fracture in Non-Institutionalized Older Adults: A Case-Control Study Nested in a Cohort

Purpose

To identify factors associated with recovered functionality after a hip fracture in a sample of older adult patients.

Patients and Methods

Nested case-control study in a cohort. Older adults (60 years or older) with a hip fracture were recruited between May 2017 and October 2018. The Barthel scale was used to measure performance in activities of daily living (ADL). A questionnaire was applied to collect information about demographic, clinic, psychological and social variables, and anthropometric measurements were taken. A logistic regression model was built to analyze various factors related to recovered functionality.

Results

A total of 346 older adults with a hip fracture were studied (n=173 cases and n=173 controls); 69.4% (n=240) women and 30.6% (n=140) men. Mean age was 79.4 years (±8.7) overall; for cases, 77.4 (±7.9) years and for controls, 81.4 (±9.0). Mean schooling was 6.3 (± 4.3) years. Recovered functionality was associated with normal nutritional status (OR 4.81, 95% CI = 2.54–9.12), absence of heart disease (OR 4.08, 95% CI = 1.48–11.20), self-efficacy for ADL (OR 4.07, 95% CI = 2.15–7.72), absence of depressive symptoms (OR 2.99, 95% CI = 1.69–5.28), prior functionality (OR 2.83, 95% CI = 1.51–5.31), high socioeconomic level (OR 2.41, 95% CI = 1.24–4.65) and transcervical fracture (OR 2.34, 95% CI = 1.05–5.22).

Conclusion

In older adults who have suffered a hip fracture, clinical, psychological, and demographic characteristics are associated with recovered functionality. These factors should be considered as a priority in the care of older adults who have experienced hip fractures.

Rehabilitation Concerns in the Geriatric Critically Ill and Injured - Part 2

As life expectancy increases and birth rates decline, the geriatric population continues to grow faster than any other age group. Aging is characterized by a progressive physiologic decline that promotes the onset of functional limitation and disability. With the increasing geriatric population, more elderly patients are presenting to emergency departments after trauma, and intensive care units are being met with increasing demand. Rehabilitation is critical in improving quality of life by maximizing physical, cognitive, and psychological recovery from injury or disease.

Prognostic factors related to ambulation deterioration after 1-year of geriatric hip fracture in a Chinese population

The objective of this study was to investigate the prognostic factors predicting the ambulation recovery of fragility hip fracture patients. 2286 fragility hip fracture patients were collected from the Fragility Fracture Registry in Hong Kong. Predictive factors of ambulation deterioration including age, gender, pre-operation American Society of Anesthesiologists grade, pre-fracture mobility, delay to surgery, length of stay, fracture type, type of surgery, discharge destination and complications were identified. Patients with outdoor unassisted and outdoor with aids ambulatory function before fracture had 3- and 1.5-times increased risk of mobility deterioration, respectively (Odds Ratio (OR) = 2.556 and 1.480, 95% Confidence Interval (CI) 2.101–3.111 and 1.246–1.757, both p < 0.001). Patients living in old age homes had almost 1.4 times increased risk of deterioration when compared to those that lived in their homes (OR = 1.363, 95% CI 1.147–1.619, p < 0.001). The risk also increased for every 10 years of age (OR = 1.831, 95% CI 1.607–2.086, p < 0.001). Patients in the higher risk ASA group shows a decreased risk of ambulation deterioration compared to those in lower risk ASA group (OR = 0.831, 95% CI 0.698–0.988, p = 0.038). Patients who suffered from complications after surgery did not increased risk of mobility decline at 1-year post-surgery. Delayed surgery over 48 h, delayed discharge (> 14 days), early discharge (less than 6 days), and length of stay also did not increased risk of mobility decline. Male patients performed worse in terms of their mobility function after surgery compared to female patients (OR = 1.195, 95% CI 1.070–1.335, p = 0.002). This study identified that better premorbid good function, discharge to old age homes especially newly institutionalized patients, increased age, lower ASA score, and male patients, correlate with mobility deterioration at 1-year post-surgery. With the aging population and development of FLS, prompt identification of at-risk patients should be performed for prevention of deterioration.

Pre-operative epidural analgesia in hip fracture patients - A systematic review and meta-analysis

BACKGROUND

Hip fracture is a common, painful injury with increasing global incidence. Patients require optimal acute pain management. Systematic reviews have investigated the postoperative use of epidural analgesia and found that it may have advantages over systemic analgesia. It is of interest to determine whether pre-operative use of epidural analgesia is also advantageous. We conducted a systematic review and meta-analyses on the effect of epidural analgesia on pre-operative pain management in hip fracture patients.

METHODS

We included randomized controlled trials comparing pre-operatively initiated epidural analgesia with any other method of analgesia, in adults aged ≥55 years scheduled for hip fracture surgery. The main outcome was pre-operative pain at rest. Electronic searches of four medical databases were performed. Two authors independently screened for eligibility, extracted data, and assessed risk of bias. We conducted meta-analyses and assessed the certainty of the evidence by Grading of Recommendations Assessment, Development and Evaluation (GRADE).

RESULTS

Three articles were included, with 179 randomized patients. All studies compared epidural analgesia with systemic analgesia, one additionally with 3-in-1-block. Meta-analyses of pre-operative pain measurements resulted in a mean difference of -5.85 95% CI [-14.90; 3.19] on a 0-100 Visual Analogue Scale with a p-value of 0.17 and a very low certainty of evidence according to the GRADE rating.

CONCLUSIONS

We did not find a difference in pre-operative pain at rest between epidural analgesia and any other method of pre-operatively initiated analgesia. The studies were few, of low quality and the difference between the two interventions remains unknown.

Resilience in the Orthopaedic Patient

➤

Resilience is a dynamic psychological construct that refers to the ability to adapt and improve when facing adversity or other stressors.

➤

Recent investigations in various orthopaedic subspecialties have demonstrated that resilience may contribute to favorable mental health and physical function after a surgical procedure.

➤

More research, using well-designed prospective studies, is necessary to better define the role that resilience and other factors play in the health and outcomes of patients with orthopaedic conditions.

➤

Orthopaedic surgeons can consider incorporating resilience assessments into their practices to aid in identifying patients who will do well with a surgical procedure and those who may benefit from specialized therapy to optimize their health and function.

What Factors Predict Adverse Discharge Disposition in Patients Older Than 60 Years Undergoing Lower-extremity Surgery? The Adverse Discharge in Older Patients after Lower-extremity Surgery (ADELES) Risk Score

BACKGROUND

Adverse discharge disposition, which is discharge to a long-term nursing home or skilled nursing facility is frequent and devastating in older patients after lower-extremity orthopaedic surgery. Predicting individual patient risk allows for preventive interventions to address modifiable risk factors and helps managing expectations. Despite a variety of risk prediction tools for perioperative morbidity in older patients, there is no tool available to predict successful recovery of a patient's ability to live independently in this highly vulnerable population.

QUESTIONS/PURPOSES

In this study, we asked: (1) What factors predict adverse discharge disposition in patients older than 60 years after lower-extremity surgery? (2) Can a prediction instrument incorporating these factors be applied to another patient population with reasonable accuracy? (3) How does the instrument compare with other predictions scores that account for frailty, comorbidities, or procedural risk alone?

METHODS

In this retrospective study at two competing New England university hospitals and Level 1 trauma centers with 673 and 1017 beds, respectively; 83% (19,961 of 24,095) of patients 60 years or older undergoing lower-extremity orthopaedic surgery were included. In all, 5% (1316 of 24,095) patients not living at home and 12% (2797 of 24,095) patients with missing data were excluded. All patients were living at home before surgery. The mean age was 72 ± 9 years, 60% (11,981 of 19,961) patients were female, 21% (4155 of 19,961) underwent fracture care, and 34% (6882 of 19,961) underwent elective joint replacements. Candidate predictors were tested in a multivariable logistic regression model for adverse discharge disposition in a development cohort of all 14,123 patients from the first hospital, and then included in a prediction instrument that was validated in all 5838 patients from the second hospital by calculating the area under the receiver operating characteristics curve (ROC-AUC).Thirty-eight percent (5360 of 14,262) of patients in the development cohort and 37% (2184 of 5910) of patients in the validation cohort had adverse discharge disposition. Score performance in predicting adverse discharge disposition was then compared with prediction scores considering frailty (modified Frailty Index-5 or mFI-5), comorbidities (Charlson Comorbidity Index or CCI), and procedural risks (Procedural Severity Scores for Morbidity and Mortality or PSS).

RESULTS

After controlling for potential confounders like BMI, cardiac, renal and pulmonary disease, we found that the most prominent factors were age older than 90 years (10 points), hip or knee surgery (7 or 8 points), fracture management (6 points), dementia (5 points), unmarried status (3 points), federally provided insurance (2 points), and low estimated household income based on ZIP code (1 point). Higher score values indicate a higher risk of adverse discharge disposition. The score comprised 19 variables, including socioeconomic characteristics, surgical management, and comorbidities with a cutoff value of ≥ 23 points. Score performance yielded an ROC-AUC of 0.85 (95% confidence interval 0.84 to 0.85) in the development and 0.72 (95% CI 0.71 to 0.73) in the independent validation cohort, indicating excellent and good discriminative ability. Performance of the instrument in predicting adverse discharge in the validation cohort was superior to the mFI-5, CCI, and PSS (ROC-AUC 0.72 versus 0.58, 0.57, and 0.57, respectively).

CONCLUSION

The Adverse Discharge in Older Patients after Lower Extremity Surgery (ADELES) score predicts adverse discharge disposition after lower-extremity surgery, reflecting loss of the ability to live independently. Its discriminative ability is better than instruments that consider frailty, comorbidities, or procedural risk alone. The ADELES score identifies modifiable risk factors, including general anesthesia and prolonged preoperative hospitalization, and should be used to streamline patient and family expectation management and improve shared decision making. Future studies need to evaluate the score in community hospitals and in institutions with different rates of adverse discharge disposition and lower income.

The Pronounced Impact of Hip Fractures on Psychosocial Well-being

BACKGROUND

There are little data on the psychosocial well-being of hip fracture patients. Previous studies lacked a control group to isolate the impact of hip fractures from general aging. We sought to overcome these limitations and quantify the impact of hip fractures on psychosocial well-being.

METHODS

We identified a cohort 65 years and older patients who were driving and mobile from the National Health and Aging Trends Study. Participants with exactly one hip fracture between 2011 and 2017 were isolated, and their outcomes an after hip fracture were compared with control subjects via multivariate logistic regression.

RESULTS

Hip fracture patients reported a notable decrease in driving frequency and mobility in the first year after fracture, along with an increase in depressive symptomatology and decreased participation in activities. Measures of mobility and activities among survivors returned to peer group levels within 2 years. A larger social network was associated with improved outcomes.

DISCUSSION

Hip fracture survivors experience notable declines in function and well-being in the first year after a hip fracture compared with peers. Although mortality is high, surviving patients experience measurable gains in function and well-being in the 3 years after the fracture. These data aid surgeons in counseling families and patients after hip fracture.

LEVEL OF EVIDENCE

Prevalence of depression in older people with hip fracture: A systematic review and meta-analysis

INTRODUCTION

Hip fracture disrupts general health and is one of the most common physical injuries in the elderly. Depression is the most common mood disorder in older people and one of the main complications of hip fractures.

AIM AND METHODS

We conducted a meta-analysis to estimate the prevalence of depression in older people with hip fractures. Relevant literature published until July 2019 was obtained and screened according to established inclusion criteria. Two researchers independently carried out quality assessment and data extraction before the meta-analysis. We calculated proportions with 95% confidence intervals (CI). To investigate the sources of heterogeneity, we performed subgroup analyses based on study design, follow-up duration, type of fracture, and gender.

RESULTS

Twenty-seven studies with a combined sample size of 11958 were included. The overall prevalence of depression in older people with hip fracture was 23% (95% CI: 0.18 to 0.29). The lowest and highest prevalence of depression was in Asia (0.19) and America (0.27) respectively.

CONCLUSION

In this systematic review and meta-analysis the estimated prevalence of depression among older hip fracture patients was 23%. Further research is needed to identify strategies for preventing and treating mood disorders in this population.

Preoperative Depressive Symptoms Associated with Poor Functional Recovery after Surgery

BACKGROUND/OBJECTIVES

Depression screening and treatment for older adults are recommended in Age-Friendly Health Systems. Few studies have evaluated the association between depressive symptoms and postoperative functioning. We aimed to determine the association between varying levels of depressive symptoms in the preoperative setting with postoperative functional recovery.

DESIGN

Prospective cohort study.

SETTING

Two academic hospitals in Boston, Massachusetts.

PARTICIPANTS

Surgical patients aged 70 and older (N = 560).

MEASUREMENTS

Participants were assessed preoperatively and 1 year postoperatively. Preoperative evaluation included the 15-item short-form Geriatric Depression Scale (GDS). Results were categorized as low (GDS = 0-1), moderate (2-5), or high (6-15) symptom burden. Primary outcome was 1-year instrumental activities of daily living functional decline. Secondary outcomes included hospital stay longer than 5 days, discharge to post-acute care (PAC) facility, and readmission within 30 days.

RESULTS

Mean participant age was 76.6 ± 5 years, 58% were women, 81% underwent an orthopedic operation, 13% gastrointestinal, 6% vascular; 13% had functional decline at 1 year after their operation (by symptom burden: low = 5.5%; moderate = 14.8%, and high = 38.6%). After adjusting for age, sex, and comorbidity, those with moderate or high depressive symptoms demonstrated greater odds of functional decline at 1 year compared with those with a low symptom burden (moderate: adjusted odds ratio [AOR] = 2.7; 95% confidence interval [CI] = 1.3-5.3; high: AOR = 9.3; 95% CI = 4.2-20.6), discharge to PAC facility (moderate: AOR = 1.7; 95%CI = 1.2-2.6; high: AOR = 2.7; 95% CI = 1.4-5.1) but demonstrated no significant association with 30-day readmission or hospital length of stay longer than 5 days.

CONCLUSION

Greater burden of preoperative depressive symptoms is associated with increased likelihood of functional decline at 1 year after surgery and of discharge to PAC facility. Preoperative assessment of the burden of depressive symptoms in older adults undergoing elective surgery may be helpful in identifying patients at high risk of poor outcomes.

Adverse effects of Z-drugs for sleep disturbance in people living with dementia: a population-based cohort study

BACKGROUND

Sleep disturbance is common in dementia and often treated with Z-drugs (zopiclone, zaleplon, and zolpidem). While some observational studies suggest that Z-drugs are associated with adverse events such as falls and fracture risks in older people, this has not been studied in dementia.

METHODS

We used data from 27,090 patients diagnosed with dementia between January 2000 and March 2016 from the Clinical Practice Research Datalink linked to Hospital Episodes Statistics data in England. We compared adverse events for 3532 patients newly prescribed Z-drugs by time-varying dosage to (1) 1833 non-sedative-users with sleep disturbance; (2) 10,214 non-sedative-users with proximal GP consultation matched on age, sex, and antipsychotic use; and (3) 5172 patients newly prescribed benzodiazepines. We defined higher dose Z-drugs and benzodiazepines as prescriptions equivalent to ≥ 7.5 mg zopiclone or > 5 mg diazepam daily. Cox regression was used to estimate hazard ratios (HRs) for incident fracture, hip fracture, fall, mortality, acute bacterial infection, ischaemic stroke/transient ischaemic attack, and venous thromboembolism over a 2-year follow-up, adjusted for demographic- and health-related covariates.

RESULTS

The mean (SD) age of patients was 83 (7.7) years, and 16,802 (62%) were women. Of 3532 patients prescribed Z-drugs, 584 (17%) were initiated at higher doses. For patients prescribed higher dose Z-drugs relative to non-users with sleep disturbance, the HRs (95% confidence interval) for fractures, hip fractures, falls, and ischaemic stroke were 1.67 (1.13-2.46), 1.96 (1.16-3.31), 1.33 (1.06-1.66), and 1.88 (1.14-3.10), respectively. We observed similar associations when compared to non-sedative-users with proximal GP consultation. Minimal or inconsistent excess risks were observed at ≤ 3.75 mg zopiclone or equivalent daily, and for mortality, infection, and venous thromboembolism. We observed no differences in adverse events for Z-drugs compared to benzodiazepines, except lower mortality rates with Z-drugs (HR [95% confidence interval] of 0.73 [0.64-0.83]).

CONCLUSIONS

Higher dose Z-drug use in dementia is associated with increased fracture and stroke risks, similar or greater to that for higher dose benzodiazepines. Higher dose Z-drugs should be avoided, if possible, in people living with dementia, and non-pharmacological alternatives preferentially considered. Prescriptions for higher dose Z-drugs in dementia should be regularly reviewed.

Subjective memory complaints predict poorer functional recovery during the first year following hip-fracture surgery among elderly adults

OBJECTIVES

Subjective memory complaints (SMCs) in the elderly are associated with poor recovery in performing activities of daily living. This study was designed to examine SMCs and their association with recovery and health outcomes of older persons within 1 year following hospital discharge after hip-fracture surgery.

METHODS

Data were collected between 2012 and 2015 from 194 hip-fractured elders in northern Taiwan. SMCs were assessed by the Prospective and Retrospective Memory Questionnaire. Recovery outcomes included self-care ability (activities of daily living [ADLs] and instrumental activities of daily living [IADLs]), physical function (range of motion and maximal muscle strength), cognitive function, delirium, depressive symptoms, and health-related quality of life (HRQoL). Outcomes were assessed before discharge and 1, 3, 6, and 12 months afterwards. Associations of SMCs with participants' recovery outcomes were examined by the generalized estimating equation approach.

RESULTS

Participants with SMCs had significantly poorer recovery outcomes than those without SMCs. Additionally, the interaction term for time-by-SMC was significant on ADLs, IADLs, maximal strength of quadriceps muscles, maximal strength of hip abductor muscles, ankle dorsiflexion, and HRQoL, suggesting that negative associations with SMCs increased over time. Participants with SMCs were at significantly higher risk for cognitive impairment and delirium than those without SMCs.

CONCLUSIONS

Participants with SMCs not only had worse recovery than those without SMCs, but their rate of recovery was also slower during the first year following hip-fracture surgery. Therefore, SMCs need to be assessed to identify patients at high risk for worse recovery outcomes following hip fracture.

Independent factors associated with long-term functional outcomes in patients with a proximal femoral fracture: A systematic review

INTRODUCTION

The current understanding of prognostic factors of functional recovery after a proximal femoral fracture is limited, and enhancements could improve the prognostic accuracy and target subgroups for additional care strategies. This systematic review aims to identify all studied factors with an independent prognostic value for the long-term functional recovery of patients with a proximal femoral fracture.

MATERIALS AND METHODS

Observational studies with multivariate analyses on prognostic factors of long-term functional outcome after proximal femoral fractures were obtained through an electronic search performed on November 9, 2018.

RESULTS

In the 31 included articles, thirteen prognostic factors were studied by at least two independent studies and an additional ten by only one study. Age, comorbidity, functionality and cognition were factors for which the majority of studies indicated a significant effect. The majority of studies which included sex as a factor found no significant effect. The level of evidence for the remaining factors was deemed too low to be conclusive on their relevance for long-term functional outcome.

CONCLUSION

The identified factors showed overlap with prognostic factors of short-term functional outcomes and mortality. The validity and applicability of prognostic models based on these factors may be of interest for future research.

Natural History of Cognitive Impairment in Critical Illness Survivors. A Systematic Review

Long-term cognitive impairment is common among ICU survivors, but its natural history remains unclear. In this systematic review, we report the frequency of cognitive impairment in ICU survivors across various time points after ICU discharge that were extracted from 46 of the 3,350 screened records. Prior studies used a range of cognitive instruments, including subjective assessments (10 studies), single or screening cognitive test such as Mini-Mental State Examination or Trail Making Tests A and B (23 studies), and comprehensive cognitive batteries (26 studies). The mean prevalence of cognitive impairment was higher with objective rather than subjective assessments (54% [95% confidence interval (CI), 51–57%] vs. 35% [95% CI, 29–41%] at 3 months after ICU discharge) and when comprehensive cognitive batteries rather than Mini-Mental State Examination were used (ICU discharge: 61% [95% CI, 38–100%] vs. 36% [95% CI, 15–63%]; 12 months after ICU discharge: 43% [95% CI, 10–78%] vs. 18% [95% CI, 10–20%]). Patients with acute respiratory distress syndrome had higher prevalence of cognitive impairment than mixed ICU patients at ICU discharge (82% [95% CI, 78–86%] vs. 48% [95% CI, 44–52%]). Although some studies repeated tests at more than one time point, the time intervals between tests were arbitrary and dictated by operational limitations of individual studies or chosen cognitive instruments. In summary, the prevalence and temporal trajectory of ICU-related cognitive impairment varies depending on the type of cognitive instrument used and the etiology of critical illness. Future studies should use modern comprehensive batteries to better delineate the natural history of cognitive recovery across ICU patient subgroups and determine which acute illness and treatment factors are associated with better recovery trajectories.

A two-year multicenter point prevalence study of older patients with hip fractures admitted to rehabilitation units in Italy

PURPOSE

To date in Italy we do not have sufficient information on the rehabilitation process of older patients with hip fractures especially in the context of dementia. The main aims of the study were to gather information on the characteristics of older patients with hip fracture admitted to rehabilitation units with a specific focus on geriatric syndromes and the rehabilitation process.

METHODS

A national multi-center "point prevalence study" was conducted in Italy over two index days in 2017 and 2018. All patients aged 70 years and older hospitalized on the index day in Rehabilitation Units after a hip fracture were eligible.

RESULTS

A total of 615 patients were included. Most of the hospitals involved were from northern Italy, to a lesser extent from central and from southern Italy. The mean age was 83.08 ± 7.9 years. Almost half of the patients lived alone before the hip fracture. Most of the falls happened at home and while walking. The prevalence of delirium, dementia and malnutrition was 9.1%, 36.6%, and 19.3%, respectively. Antidepressants were prescribed in 27% of the population. The multidisciplinary team was activated as follows: occupational therapist in 18.9% of the cases, psychologists in 14.5%, social workers in 15.3%, and speech therapists in 6.5%.

CONCLUSION

The study allowed the collection of data on a relatively large sample of older patients with hip fracture showing the possible current limitations in the correct management of geriatric syndromes in this frail population. Future multicenter longitudinal studies are required to further study this population.

Postacute Management of Older Adults Suffering an Osteoporotic Hip Fracture: A Consensus Statement From the International Geriatric Fracture Society

BACKGROUND

The majority of patients require postacute care (PAC) after a hip fracture. Despite its importance, there is no established consensus regarding the standards of care provided to hip fracture patients in PAC facilities.

METHODOLOGY

A writing group was created by professionals from the International Geriatric Fracture Society (IGFS) with representation from other organizations. The focus of the statements included in this article is toward PAC providers located in nursing facilities. Contributions were integrated in a single document that underwent several reviews by each author and then underwent a final review by the lead and senior authors. After this process was completed, the document was appraised by reviewers from IGFS.

RESULTS/CONCLUSION

A total of 15 statements were crafted. These statements summarize the best available evidence and is intended to help PAC facilities managing older adults with hip fractures more efficiently, aiming toward overall better outcomes in the areas of function, quality of life, and with less complications that could interfere with their optimal recovery.

Preoperative Depression and Plasma Cortisol Levels as Predictors of Delirium after Cardiac Surgery

BACKGROUND

Delirium is common in old patients who undergo cardiac surgery, and it is associated with adverse outcomes. The genesis of delirium is thought to be multi-factorial, but it is still not well understood. Symptoms of depression and elevated cortisol level have been described in some previous studies as factors associated with delirium, suggesting a shared pathophysiology.

AIMS

The objective of the present study was to determine whether preoperative depression symptoms and increased cortisol level represent risk factors for delirium after cardiac surgery.

METHODS

We performed a prospective cohort study in 183 patients aged >50 years undergoing elective cardiac surgery. The Geriatric Depression Scale (GDS) was used to assess patients for depressive symptoms before surgery. Preoperative plasma cortisol levels were available in 145 participants. Delirium was diagnosed using the Confusion Assessment Method for Intensive Care Unit (CAM-ICU) during the first 7 days after surgery. Spearman correlation was used for correlations between GDS, Mini-Mental State Examination (MMSE), Charlson comorbidity index, and age. Binary logistic regression was used to determine whether GDS and cortisol levels predict postoperative delirium.

RESULTS

Delirium occurred in 60 patients out of 183 (32.8%) included and lasted 2.3 days (SD 1.36). GDS was correlated with age (p = 0.001) and comorbidity index (p = 0.003) and inversely correlated with MMSE score (p < 0.001). Higher preoperative GDS scores were associated with incidence of delirium in the postoperative period (p = 0.002). The association was significant after controlling for age, MMSE score, history of stroke, and Charlson comorbidity index (p = 0.045). Preoperative cortisol level was not associated with the development of postoperative delirium.

CONCLUSION

Our results suggest that a higher preoperative depression score is associated with an increased risk of postoperative delirium. On the other hand, preoperative plasma cortisol level does not seem to be a predictor of delirium after surgery. Further studies are needed to determine the potential of preoperative depression treatment to prevent postoperative delirium.

Post-acute Use of Opioids and Psychotropics in Patients after Hip Fracture: Unintended Consequences of Implementing Diagnosis-Related Grouping Payment

OBJECTIVE

How implementing diagnostic-related grouping (DRG) payment affected the use of opioids and psychotropics by hip fracture patients following hospitalization remained unknown.

DESIGN

A retrospective, pre-post design, cohort study of data excerpted from Taiwan's National Health Insurance Research database (NHIRD).

SETTING AND PARTICIPANTS

Adults aged ≥ 65 years first admitted for hip fracture surgery from 2007 to 2012 were identified and divided into two 1:1 propensity-score matched groups: pre-DRG (2007-2009); DRG (2010-2012).

MEASUREMENTS

The outcome measures were use of opioid and/or psychotropic drugs within 30 days, 90 days, 180 days, and 365 days after discharge.

RESULTS

Data of 16,522 subjects were excerpted, and 8,261 propensity-score matched subjects each classified into the pre-DRG and DRG groups. After adjustment, the DRG group was significantly more likely than the pre-DRG group to have used antipsychotics after discharge from hip fracture surgery (≤30 days, ≤90 days, ≤180 days and ≤365 days). The DRG group also had significantly higher prescription rates of benzodiazepines and antipsychotics during the observation period. Moreover, the DRG group was less likely to use non-steroidal anti-inflammatory drugs (≤30 days, ≤90 days, ≤180 days and ≤365 days) and more likely to use acetaminophen (≤30 days, ≤180 days, and ≤365 days).

CONCLUSIONS

In conclusion, DRG implementation in Taiwan substantially increased post-acute prescription of antipsychotic and psychotropic agents for hip fracture patients, and changed use of analgesics, which may result in suboptimal quality and safety for these patients. Further research is needed to evaluate the long-term outcomes of DRG implementation, and the potential benefits of appropriate post-acute care bundled with DRG payment.

Is Occupational Therapy After Hip Fracture Surgery Effective in Improving Function?: A Systematic Review and Meta-Analysis of Randomized Controlled Studies

OBJECTIVE

The aim of the study was to evaluate whether occupational therapy (OT) improves activities of daily living and overall physical functioning of patients after hip fracture surgery.

DATA SOURCES

The data sources are PubMed-Medline, Embase, and Cochrane Library databases.

REVIEW METHODS

We searched for randomized controlled trials comparing occupational therapy with comprehensive postoperative care (without occupational therapy) after hip fracture surgery. A pairwise meta-analysis using fixed- and random-effects models was performed. The primary outcome of interest was performance of activities of daily living assessed in any manner. The secondary outcomes were other functional parameters: (1) physical function; (2) health perception and emotion; and (3) fall occurrence. Effect sizes were computed as standardized mean differences with 95% confidence intervals.

RESULTS

Five randomized controlled trials including a total of 524 participants were retrieved. There was a trend toward improvement in activities of daily living, physical function, and fall occurrence, and these changes were not significant. However, health perception and patient emotions improved significantly in the occupational therapy group (standardized mean difference = 0.391, 95% confidence interval = 0.104 to 0.678, P = 0.008).

CONCLUSIONS

Occupational therapy after hip fracture surgery seems to improve overall function. Indeed, the positive effects of occupational therapy on health perception and emotions were evident. Therefore, occupational therapy can be suggested in comprehensive rehabilitation programs after hip fracture surgery.

[Dementia-specific characteristics of patients with fall-related femur fractures : A case study based on routine hospital data of patients with unspecified dementia]

BACKGROUND

A fall-related femur fracture is one of the most frequent reasons for hospital admission of patients with dementia. The aim of the study was to identify dementia-specific characteristics of patients with fall-related femur fractures and additionally an unspecified dementia in order to gain further knowledge about this particular patient group.

METHODS

A descriptive explorative case study with a single case-embedded design based on routine hospital data from a university hospital was performed. A total number of 34 patient records from 2015 were analyzed. In the embedded unit of analysis I the data of selected items of the nursing assessment AcuteCare (ePA-AC©) were descriptively analyzed for the time of admission and discharge. In the embedded unit of analysis II a summarizing inductive content analysis was conducted.

RESULTS

The results of the embedded unit of analysis I showed that this patient group is characterized by a high need for care, changes of cognition and behavioral symptoms. The status of cognition, behavior and reciprocity as well as the self-care index stagnated or deteriorated in many patients from admission to discharge. The embedded unit of analysis II identified observable (social)behavior, (non)compliance and orientation as central dementia-specific characteristics.

CONCLUSION

The results reflect the complexity of the care situation of patients with unspecified dementia in acute care hospitals. The results showed that a higher awareness for this particular patient group is needed to improve outcomes.

Role of Wearable Accelerometer Devices in Delirium Studies: A Systematic Review

We sought to determine the feasibility of using wearable accelerometer devices for determining delirium effects on patients' physical activity patterns and detecting delirium and delirium subtype.

DATA SOURCES

PubMed, Embase, and Web of Science.

STUDY SELECTION

Screening was performed using predefined search terms to identify original research studies using accelerometer devices for studying physical activity in relation to delirium.

DATA EXTRACTION

Key data were extracted from the selected articles.

DATA SYNTHESIS

Among the 14 studies identified, there were a total of 315 patients who wore accelerometer devices to record movements related to delirium. Eight studies (57.1%) used accelerometer devices to compare the activity of delirious and nondelirious patients. Delirious patients had lower activity levels, lower restlessness index, higher number of daytime immobility minutes, lower mean activity levels during the day, and higher mean activity levels at night. Delirious patients also had lower actual sleep time, lower sleep efficiency, fewer nighttime minutes resting, fewer minutes resting over 24 hours, and smaller change in activity from day to night. Six studies (42.9%) evaluated the feasibility of using accelerometer devices for detection of delirium and its subtype. Variables including number of postural changes during daytime, frequency of ultrashort, short, and continuous movements were significantly different among the nondelirium and the three delirium subtypes.

CONCLUSIONS

The results from the studies using accelerometer devices in studying delirium demonstrate that accelerometer devices can potentially detect the differences between delirious and nondelirious patients, detect delirium, and determine delirium subtype. We suggest the following directions as the next steps for future studies using accelerometer devices for predicting delirium: benchmark studies with longer data collection, larger and more diverse population size, incorporating related factors (e.g., medications), and evaluating delirium subtype and severity.

Cognitive status following a hip fracture and its association with postoperative mortality and activities of daily living: A prospective comparative study of two prehospital emergency care procedures

INTRODUCTION

Early assessment of hip fracture patients' cognitive function is important for preventing pre- and postoperative complications. The aim of this study was twofold: (1) to assess prehospital cognitive function in hip fracture patients and establish whether cognitive status differs pre- and postoperatively between prehospital fast track care (PFTC) and the traditional emergency department (ED) pathway and (2) whether preoperative cognitive function is associated with postoperative mortality and activities of daily living (ADL) ability.

METHODS

Three hundred and ninety one hip fracture patients were prospectively included. The Short Portable Mental Status Questionnaire (SPMSQ) was used prehospital, at the orthopaedic ward and three days postoperatively. ADL was followed up after four months.

RESULTS

No difference in patients' cognitive function was observed between PFTC and ED. Four-month mortality was 37% for patients with dementia, 21% for those with cognitive impairment and 10% for patients without cognitive impariment. Only 26% of patients with dementia and 47% with cognitive impairment had full ADL ability, compared with 70% of patients with intact cognitive function (p < 0.001).

CONCLUSION

PFTC did not influence hip fracture patients' cognitive function. Patients with prehospital cognitive impairment had a poor outcome in terms of mortality and ADL, indicating the need for special care interventions.

Timeline of functional recovery after hip fracture in seniors aged 65 and older: a prospective observational analysis

We investigated the timeline of functional recovery after hip fracture over 12 months in adults age ≥ 65 years using objective lower extremity function tests and subjective physical functioning. Objective functional recovery was largely complete in the first 6 months, whereas subjective recovery improved up to 9 months after hip fracture.

INTRODUCTION

Hip fractures are a major cause of loss of function among seniors. We assessed the timeline of objective and subjective functional recovery after hip fracture.

METHODS

We conducted a prospective observational secondary analysis of a 1-year clinical trial on vitamin D and home exercise treatment and complications after hip fracture among 173 patients age ≥ 65 years (mean age 84 years; 79.2% women; 77.4% community-dwelling) conducted from January 2005 through December 2007. Lower extremity function (Timed Up and Go test (TUG), knee extensor and flexor strength) and grip strength was assessed at baseline and at 6 and 12 months follow-up. Subjective physical functioning was assessed using the SF-36 questionnaire also at 3 and 9 months follow-up. Multivariable-adjusted repeated-measures models were used to assess the timeline of functional recovery in the total population and in subgroups of patients.

RESULTS

Lower extremity function including TUG (- 61.1%), knee extensor (+ 17.6%), and knee flexor (+ 11.6%) strength improved significantly in the first 6 months (P < 0.001). However, between 6 and 12 months, there was no further significant improvement for any of the functional tests. Grip strength decreased from baseline to 6 months (- 7.9%; P < 0.001) and from 6 to 12 months (- 10.8%; P < 0.001). Subjective physical functioning improved from 3 to 9 months (+ 15.2%, P < 0.001), but no longer thereafter.

CONCLUSIONS

Functional recovery after hip fracture may be largely complete in the first 6 months for objective functional tests, whereas may extend up to 9 months for subjective recovery, with oldest-old, female, institutionalized, and cognitively impaired patients recovering most poorly.

Advanced prediction of functional outcomes in hip fracture patients using premorbid functional assessments

Purpose:

This historical cohort study aims to determine the relationship between premorbid functional status and functional decline in hip fracture patients.

Methods:

Eighty-two hip fracture patients were divided into Group A (good rehabilitation potential) and Group B (fair rehabilitation potential) based on four premorbid functional assessments: Modified Functional Ambulation Category (MFAC), Modified Barthel Index (MBI), Hong Kong Montreal Cognitive Assessment 5-Minute and functional prognosis predictive score. Declines in MFAC and MBI after rehabilitation were compared.

Results:

Sixty-seven percent of patients in Group A had up to one category decline in final MFAC, whereas 66% in Group B had more than one category decline. Similarly, median decline in final MBI was seven in Group A versus 22 in Group B.

Conclusion:

Hip fracture patients with good rehabilitation potential have significantly fewer functional declines. It is possible for them to be directly discharged from acute hospital for outpatient rehabilitation.

Multifactorial intervention for hip and pelvic fracture patients with mild to moderate cognitive impairment: study protocol of a dual-centre randomised controlled trial (OF-CARE)

Background

A hip or pelvic fracture is a major fall-related injury which often causes a decline in mobility performance and physical activity. Over 40% of patients with hip fracture have cognitive impairment or dementia and poorer rehabilitation outcomes than those without cognitive impairment. In this subgroup, there is a lack of evidence on the best practices supporting recovery. The main aim of this study is to investigate the effects of a transitional care intervention after inpatient rehabilitation on physical activity and functional performance in this group of cognitively impaired patients.

Methods/design

This dual-centre, randomised controlled trial compares a multifactorial intervention with usual care as control condition. Two hundred and forty community-dwellers (≥ 65 years) with a hip or pelvic fracture and mild to moderate cognitive impairment (MMSE 17–26) are recruited at the end of inpatient rehabilitation.

The four-month intervention consists of (a) an individually tailored, progressive home exercise program and physical activity promotion delivered by professional instructors and lay instructors (two home visits per week) and (b) a long-term care counselling approach addressing unmet care needs, pleasurable activities, and caregiver issues if needed. Primary outcome parameters are physical activity, measured as daily walking duration with an accelerometer-based activity monitor (activPAL™) over 72 h, and functional performance, assessed with Short Physical Performance Battery sum scores. Secondary outcome parameters are fear of falling, fall related self-efficacy, falls, quality of life, depression and activity of daily living. Data are collected at the end of rehabilitation, before the intervention at the patient’s home (baseline), after four months (post-intervention), and seven months (follow-up). In addition to completer and intent-to-treat analyses of outcomes, economic data and incremental cost-effectiveness are analysed.

Discussion

Existing service models of volunteer services and legal counselling provided by care counsellors were considered when developing the intervention protocol. Therefore, it should be feasible to translate and deliver the intervention into real-world practice if it has been demonstrated to be effective.
