Predicting discharge location of hip fracture patients; the new discharge of hip fracture patients score

Predictors of returning home after hip fracture: a prospective cohort study using the UK National Hip Fracture Database (NHFD)

INTRODUCTION

our objective was to describe trends in returning home after hospitalisation for hip fracture and identify predictive factors of this important patient-focussed outcome.

METHODS

a cohort of hip fracture patients from England and Wales (2018-2019) resident in their own home pre-admission were analysed to identify patient and service factors associated with returning home after hospital discharge, and with living in their own home at 120 days. Geographical variation was also analysed.

RESULTS

analysis of returning home at discharge included 87,797 patients; 57,104 (65%) were discharged home. Patient factors associated with lower likelihood of discharge home included cognitive impairment (odds ratio (OR) 0.60 [95% CI: 0.57, 0.62]), malnutrition (OR 0.81 [0.76, 0.86]), being at risk of malnutrition (OR 0.81 [0.78, 0.85]) and experiencing delay to surgery due to reversal of anti-coagulant medication (OR 0.84 [0.77, 0.92]). Corresponding service factors included surgery delay due to hospital logistical reasons (OR 0.91 [0.87, 0.95]) and early morning admission between 4:00 and 7:59 am (OR 0.83 [0.78, 0.89]). Nerve block prior to arrival at the operating theatre was associated with higher likelihood of discharge home (OR 1.07 [1.03, 1.11]). Most of these associations were stronger when analysing the outcome 'living in their own home at 120 days', in which two out of 11 geographic regions were found to have significantly more patients returning home.

CONCLUSION

we identify numerous modifiable factors associated with short-term and medium-term return to own home after hip fracture, in addition to significant geographical variation. These findings should support improvements to care and inform future research.

Early Predictors for Discharge to Geriatric Rehabilitation after Hip Fracture Treatment of Older Patients

OBJECTIVE

To investigate early predictors for discharge to a geriatric rehabilitation department at a skilled nursing home in older patients after hospitalization for hip fracture surgery.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

Data from 21,176 patients with hip fracture aged ≥70 years, who were registered in the Dutch Hip Fracture Audit database between January 1, 2017, and December 31, 2019, were included.

METHODS

Patients were categorized into 3 discharge groups: home (n=7326), rehabilitation (n=11,738), and nursing home (n=2112). Age, gender, Pre-Fracture Mobility Score (PFMS), premorbid Katz index of independence in Activities of Daily Living (Katz-ADL), history of dementia, American Society of Anesthesiologists physical status classification (ASA score), type of anesthesia, fracture type, surgical treatment, and cotreatment by a geriatrician were gathered. Multinomial regression analysis was used to assess for early predictors.

RESULTS

Higher age, poor premorbid mobility, lower premorbid Katz-ADL, no history of dementia, ASA score 3-5, general anesthesia, intramedullary implant, and cotreatment by a geriatrician were independent predictors for discharge to geriatric rehabilitation vs discharge home. Identical predictors were found for discharge to a nursing home vs discharge home. History of dementia and premorbid Katz-ADL were distinguishing factors; a higher premorbid Katz-ADL and a history of dementia were associated with a higher risk of discharge to a nursing home vs discharge home. The multinomial regression model correctly predicted 86%, 38.6%, and 2.4% of the patients in the rehabilitation group, home group, and nursing home group, respectively.

CONCLUSIONS AND IMPLICATIONS

This study showed that age, PFMS, premorbid Katz-ADL, surgical treatment, ASA score, type of anesthesia, history of dementia, and cotreatment by a geriatrician were independent early predictors for discharge to geriatric rehabilitation vs discharge home in older patients after hip fracture surgery. Identical predictors were found as predictors for discharge to a nursing home vs discharge home, except for history of dementia and premorbid Katz-ADL.

Positive Beliefs and the Likelihood of Successful Community Discharge From Skilled Nursing Facilities

OBJECTIVES

To examine the association of patient and direct-care staff beliefs about patients' capability to increase independence with activities of daily living (ADL) and the probability of successful discharge to the community after a skilled nursing facility (SNF) stay.

DESIGN

Retrospective cohort study of SNF patients using 100% Medicare inpatient claims and Minimum Data Set resident assessment data. Linear probability models were used to estimate the probability of successful discharge based on patient and staff beliefs about the patient's ability to improve in function, as well as patient and staff beliefs together. Estimates were adjusted for demographics, health status, functional characteristics, and SNF fixed effects.

PARTICIPANTS

Fee-for-service Medicare beneficiaries (N=526,432) aged 66 years or older who were discharged to an SNF after hospitalization for stroke, hip fracture, or traumatic brain injury.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Successful community discharge (discharged alive within 90d of SNF admission and remaining in the community for ≥30d without dying or health care facility readmission).

RESULTS

Patients with positive beliefs about their capability to increase independence with ADLs had a higher adjusted probability of successful discharge than patients with negative beliefs (positive, 63.8%; negative, 57.8%; difference, 6.0%, 95% confidence interval [CI], 5.4-6.6). This remained true regardless of staff beliefs, but the difference in successful discharge probability between patients with positive and negative beliefs was larger when staff had positive beliefs. Conversely, the association between staff beliefs and successful discharge varied based on patient beliefs. If patients had positive beliefs, the difference in the probability of successful discharge between positive and negative staff beliefs was 2.5% (95% CI, 1.0-4.0). If patients had negative beliefs, the difference between positive and negative staff beliefs was -4.6% (95% CI, -6.0 to -3.2).

CONCLUSIONS

Patients' beliefs have a significant association with the probability of successful discharge. Understanding patients' beliefs is critical to appropriate goal-setting, discharge planning, and quality SNF care.

New scoring system at admission to predict walking ability at discharge for patients with hip fracture

INTRODUCTION

A reliable scoring system that predicts the walking ability of hip fracture patients would be useful for clinicians. Here we developed a scoring system for hip fracture patients and evaluated its predictive ability.

HYPOTHESIS

We hypothesized that age, sex, presence of dementia, walking ability before the injury, fracture type, serum hemoglobin level, serum albumin level and interval in days between admission and surgery would be the predictive factors of the walking ability at discharge.

MATERIAL AND METHODS

Data from 409 patients who underwent hip fracture surgery were included. We analyzed factors that affected walking ability and developed a scoring system that predicts the probability of walking unaided or with a cane at discharge.

RESULTS

The mean age of the patients was 81.3 years. A total of 164 (40%) patients could walk unaided or with a cane at discharge. Multivariate logistic regression analysis showed that the obstructive factors for the ability to walk unaided or with a cane at discharge were older age (odds ratio [OR]=0.962, p=0.002), dementia (OR=0.126, p<0.001), use of a cane before injury (OR=0.396, p<0.001), trochanteric fracture (OR=0.571, p=0.027) and low serum albumin level (OR=4.15, p<0.001) at admission. The scoring system used the following formula: Score=5-0.04×age+albumin-2(with dementia)- 1(with use of a cane before injury)-1(with trochanteric fracture). The C-statistics for the scoring system was 0.81 (95% confidence interval, 0.77-0.85).

DISCUSSION

This newly developed scoring system of information at admission predicted the discharge mobility of hip fracture patients. In addition to the previously known risk factors, serum albumin level at admission was detected as a new predictor for mobility at discharge.

LEVEL OF PROOF

IV, retrospective study.

Predicting patients requiring discharge to post-acute care facilities following primary total hip replacement: Does anesthesia type play a role?

STUDY OBJECTIVE

We sought to develop a predictive model for discharge to post-acute care facilities in patients undergoing unilateral total hip replacement (THR). Furthermore, we sought to determine if the use of neuraxial anesthesia was an important covariate for the predictive model.

DESIGN

Retrospective observational study.

SETTING

Preoperative care and operating room at a single institution.

PATIENTS

Patients (n = 960) who underwent an elective primary THR between 2014 and 2016.

INTERVENTIONS

No intervention was performed.

MEASUREMENTS

We collected variables that were known preoperatively including age, sex, body mass index (BMI), preoperative opioid use, functional status based on metabolic equivalents (METS), preoperative anemia, thrombocytopenia, osteoarthritis and contralateral osteoarthritis grade, anesthesia type, comorbidities and surgical approach. We then performed multivariable logistic regression to develop a predictive model.

MAIN RESULTS

Female sex, preoperative opioid use, older age, general anesthesia, anemia, hypertension, a psychiatric diagnosis, use of dialysis, metabolic equivalents <4 and obesity are all risk factors for a post-acute facility discharge. The use of general anesthesia compared to neuraxial anesthesia was associated with increased odds (odds ratio 1.98, 95% confidence interval 1.31-3.00, p = 0.001) for post-acute facility discharge. Model performance was assessed using ten-fold cross-validation - the average area under the receiver operating characteristic curve calculated was 0.794.

CONCLUSIONS

We developed a predictive model for post-acute care facility discharge following THR. The use of neuraxial anesthesia was associated with decreased odds for post-acute care facility discharge.

Surgical Technical Evidence Review of Hip Fracture Surgery Conducted for the AHRQ Safety Program for Improving Surgical Care and Recovery

Background:

Enhanced recovery pathways (ERPs) have been shown to improve patient outcomes in a variety of contexts. This review summarizes the evidence and defines a protocol for perioperative care of patients with hip fracture and was conducted for the Agency for Healthcare Research and Quality safety program for improving surgical care and recovery.

Study Design:

Perioperative care was divided into components or “bins.” For each bin, a semisystematic review of the literature was conducted using MEDLINE with priority given to systematic reviews, meta-analyses, and randomized controlled trials. Observational studies were included when higher levels of evidence were not available. Existing guidelines for perioperative care were also incorporated. For convenience, the components of care that are under the auspices of anesthesia providers will be reported separately. Recommendations for an evidence-based protocol were synthesized based on review of this evidence.

Results:

Eleven bins were identified. Preoperative risk factor bins included nutrition, diabetes mellitus, tobacco use, and anemia. Perioperative management bins included thromboprophylaxis, timing of surgery, fluid management, drain placement, early mobilization, early alimentation, and discharge criteria/planning.

Conclusions:

This review provides the evidence basis for an ERP for perioperative care of patients with hip fracture.

Predictors of direct home discharge following fractured neck of femur

INTRODUCTION Direct home discharge (DHD) following hip fracture surgery represents a challenging proposition. The aim of this study was to identify factors influencing the discharge destination (home vs alternative location) for patients admitted from their own home with a fractured neck of femur. METHODS A retrospective cohort study of prospectively collected major trauma centre data was performed, identifying 10,044 consecutive hip fracture admissions between 2000 and 2012. RESULTS Two-thirds of the patients (n=6,742, 67%) were admitted from their own home. Half of these (n=3,509, 52%) returned directly to their own home while two-fifths (n=2,640, 39%) were discharged to an alternative location; 593 (9%) died. The following were identified as independent variables associated with a higher likelihood of DHD: younger patients, female sex, an abbreviated mental test score of 10, absence of certain co-morbidities, cohabiting, walking independently outdoors, no use of walking aids, no assistance required with basic activities of daily living and intracapsular fracture. CONCLUSIONS Identifying those at risk of being discharged to an alternative location following admission from home on the basis of identified preoperative indices could assist in streamlining the postoperative care phase. Pre-emptive action may help increase the numbers of patients discharged directly home and reduce the number requiring additional rehabilitation prior to discharge home with its associated socioeconomic effect.

Prognostic Value of Braden Activity Subscale for Mobility Status in Hospitalized Older Adults

OBJECTIVE

To evaluate the predictive value of the Activity subscale of the Braden Scale for Predicting Pressure Sore Risk in assessing mobility impairment and recovery among hospitalized older adults.

DESIGN

Retrospective cohort study.

SETTING

UF Health Shands Hospital, University of Florida, Gainesville, Florida.

PATIENTS

19,769 older adults (≥65 years) hospitalized between January 2009 and April 2014.

MEASUREMENTS

Incident mobility impairment and recovery were assessed with the Braden Activity subscale (BAS) score that nurses use to grade patients at every shift change (~3 times/d). Posthospital mortality rate and discharge disposition were used to assess the prognostic value of the BAS.

RESULTS

Of the 10,717 study patients observed "walking frequently" at admission, 2218 (20.7%) developed incident mobility impairment. Of the other 9052 study patients, who were impaired at admission, 4734 (52.3%) recovered to a state of walking occasionally or frequently. Older adults who developed mobility impairment during hospitalization had an odds of death higher than that of those who remained mobile (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.08- 1.39). This effect predominately occurred within the first 6 follow-up months. Older adults who recovered from mobility impairment had an odds of death lower than that of those who did not recover mobility in the hospital (OR, 0.54; 95% CI, 0.49-0.59). This effect was slightly stronger within the first 6 months after hospitalization.

CONCLUSIONS

Nurses' BAS assessment of mobility status during hospitalization provides substantial prognostic value in hospitalized older adults. The BAS could be an efficient and valuable source of information about mobility status for targeting posthospital care of older adults. Journal of Hospital Medicine 2017;12:396-401.

A Comprehensive Analysis of the Causes and Predictors of 30-Day Mortality Following Hip Fracture Surgery

BACKGROUND

A fracture neck of femur is the leading cause of injury-related mortality in the elderly population. The 30-day mortality figure is a well utilised marker of clinical outcome following a fracture neck of femur. Current studies fail to analyse all patient demographic, biochemical and comorbid parameters associated with increased 30-day mortality. We aimed to assess medical risk factors for mortality, which are easily identifiable on admission for patients presenting with a fractured neck of femur.

METHODS

A retrospective review of a prospectively populated database was undertaken to identify all consecutive patients with a fracture neck of femur between October 2008 and March 2011. All factors related to the patient, injury and surgery were identified. The primary outcome of interest was 30-day mortality. Univariate and subsequent multivariate analyses using a backward stepwise likelihood ratio Cox regression model were performed in order to establish all parameters that significantly increased the risk of death.

RESULTS

A total of 1,356 patients were included in the study. The 30-day mortality was 8.7%. The most common causes of death included pneumonia, sepsis and acute myocardial infarction. Multiple regression analysis revealed male gender, increasing age, admission source other than the patient's own home, admission haemoglobin of less than 10 g/dL, a history of myocardial infarction, concomitant chest infection during admission, increasing Charlson comorbidity score and liver disease to be significant predictors of mortality.

CONCLUSIONS

This study has elucidated risk factors for mortality using clinical and biochemical information which are easily gathered at the point of hospitalization. These results allow for identification of vulnerable patients who may benefit from a prioritisation of resources.

Geriatric preinjury activities of daily living function is associated with glasgow coma score and discharge disposition: a retrospective, consecutive cohort study

The primary objective was to evaluate the associations of the Injury Severity Score (ISS), age, Glasgow Coma Score (GCS), preexisting medical conditions (PEMC), and preinjury activities of daily living (ADL) Katz score with discharge disposition in surviving geriatric trauma patients.Data were obtained from the trauma registry. The preinjury Katz ADL score was prospectively ascertained.Of 184 consecutive surviving geriatric trauma patients with an ISS of 4 to 30, age was 80 ± 8 years and 75% fell. A PEMC was present in 93%. Preinjury ADL limitation occurred in 33%. The Katz score had inverse associations with the number of PEMCs (P< .01) and dementia (P < .01). Preinjury residence was home in 93% and nursing home in 7%. Katz scores by discharge disposition were as follows: home (36%) 5.5 ± 1; nursing home (15%) 3.6 ± 2; rehabilitation (44%) 5.6 ± 1; long-term acute care (5%) 4.0 ± 3 (P < .01). Nursing home/long-term acute care discharge was independently associated (P< .01) withlower Katz score, higher age, and lower discharge GCS; dementia and the number of PEMCs had P > .05. The discharge GCS was associated with the Katz score (P < .01), head injury score (P < .01), dementia (P < .01), and admission GCS (P < .01). The discharge GCS was independently associated (P < .01) with the Katz score and admission GCS. The admission GCS was associated with the Katz score (P = .02), ISS (P < .01), head injury score (P < .01), and dementia (P < .01). The admission GCS was independently associated (P < .05) with the Katz score and ISS.The majority of geriatric trauma survivors with an ISS of 4 to 30 are not discharged home. Lower preinjury ADL function is associated with the lower admission and discharge GCS and greater care needs at discharge. Dementia and the number of PEMCs are not independent predictors of discharge disposition.

Complications and institutionalization are almost doubled after second hip fracture surgery in the elderly patient

PURPOSE

To determine patient and hip fracture characteristics, early postoperative complication rate, and need for institutionalization at the time of discharge from the hospital in patients treated for a second contralateral hip fracture.

METHODS

During a 6-year period (2003-2009), 71 patients (60 women and 11 men; age range, 54-94 years) underwent first hip fracture surgery and subsequent contralateral hip fracture surgery at our hospital. Variables, including age, gender, American Society of Anesthesiologists classification (ASA), AO fracture classification, time between both hip fractures, rate and severity of early postoperative complications, and destination of discharge were obtained from the electronic medical records. Data from both hospitalization periods were compared.

RESULTS

Forty-six percent of second hip fractures occurred within 2 years after the first hip fracture. After the first hip fracture surgery, 13 patients had 1 or multiple complications compared with 23 patients after a second hip fracture surgery (P = 0.02). The mean time (±SD) between the first and second hip fractures in patients without complications after the second injury was 4.3 (±4.2) years, compared with 2.6 (±2.1) years in patients with complications after the second injury (P = 0.03). The mean ASA classification of patients without complications after the second hip fracture surgery was 2.6 (±0.6) versus 3.0 (±0.6) in patients with complications (P = 0.04). After the first hip fracture surgery, 27 patients (38%) were discharged to an institutional care facility, whereas 72% of patients resided at an institutional care facility after a second hip fracture.

CONCLUSIONS

Early complication rate in patients sustaining a second contralateral hip fracture was almost twice that documented after the first hip fracture. After the second hip fracture surgery, most patients resided in an institutional care facility.

Predictors of not regaining basic mobility after hip fracture surgery

PURPOSE

Regaining basic mobility after hip fracture surgery is a milestone in the in-hospital rehabilitation. The aims were to investigate predictors for not regaining basic mobility at the fifth post-operative day and at discharge after undergoing hip fracture surgery.

METHOD

In a prospective cohort study 274 hip fracture patients were included. Patients with compromised ability to exercise were excluded leaving 167 patients for analysis. Patient demographics, functional level, method of operation, post-operative hemoglobin and the completion of physiotherapy was registered. Basic mobility was assessed by the Cumulated Ambulation Score. Multivariate logistic regression was performed.

RESULTS

Age >80 years (OR = 7.5), low prefracture functional level (OR = 3.0), not completed the physiotherapy on first post-operative day (OR = 4.6) and hemoglobin <6 mmol/L measured on first post-operative day (OR = 5.8) were significant predictors of not regaining basic mobility within the fifth post-operative day (p values: 0.04 - <0.0001). Predictors of not regaining basic mobility at discharge were: Age >80 years (OR = 4.3), prefracture functional level (OR = 7.0) and not completed the physiotherapy on first post-operative day (OR = 3.3) (p values: 0.009-<0.0001).

CONCLUSIONS

This study shows that patients undergoing hip fracture surgery, who are not able to complete physiotherapy on first post-operative day, are at a greater risk of not regaining basic mobility during hospitalization. This highlights the importance of physiotherapy as part of the interdisciplinary treatment.

IMPLICATIONS FOR REHABILITATION

Regaining abilities in basic mobility after hip fracture surgery is a primary goal of rehabilitation during hospitalization in the acute ward. The following factors are indentified to predict patients not regaining their previous level of basic mobility: Age >80 years, low prefracture functional level, patients not being able to complete the physiotherapy on the first post-operative day and hemoglobin value <6 mmol/l on the first post-operative day. In future strategies, the findings regarding both modifiable and unmodifiable factors, can be used to conduct early planning of discharge and to take actions in relation to patients who are at a risk of not regaining basic mobility.

Epidemiology of osteoporotic hip fractures in Western Romania

PURPOSE

Fragility hip fractures represent a major health and social burden. To date, there are no reports regarding mortality and factors that influence outcomes after osteoporotic hip fractures in Romania.

MATERIAL AND METHODS

The electronic database of the largest healthcare provider in the western part of the country was searched for hip fracture admissions between 2008 and 2012. Inclusion criteria were age over 55 and the diagnosis of intra or extracapsular fractures, corresponding to ICD-10 S72.0 and S72.1 codes, respectively.

RESULTS

A total of 1,866 patients met the criteria and were selected for data analysis. The gain in rates and crude numbers was caused mainly by a rise of fractures in males. The opposite is seen for the female-to-male ratio. Even though the mean age steadily increased for a total of 1.5 over a five-year period the patients are still younger than the European averages, which might explain the slightly better one-year survival. The age-gender adjusted hip fracture incidence increased dramatically with age, especially in women. The relative risk of dying in the first year is 1.359 times higher if the fracture is extracapsular (95% CI 1.12-1.65). In total, 21.1% of all patients die by one year after the fracture. This was drastically reduced for the following years. The survival function is significantly dependent on age group, level of fracture and time from hospital admission until surgery (p < 0.001).

CONCLUSIONS

Increased age, extracapsular fractures and delayed surgery have worse outcomes. Regarding gender, even if not significant at the 0.05 level, probability of survival for females is higher for all time intervals. Updated, regional studies could be used in patient management to improve outcomes whilst decreasing costs.

Predictors of early mortality after hip fracture surgery

PURPOSE

The aim of this study was to examine causes and potential risk factors for 30-day mortality after hip fracture surgery (HFS) at a high-volume tertiary-care hospital.

METHODS

We retrospectively reviewed 467 patients who underwent HFS at our institution. Multivariate analysis was undertaken to identify potential predictors of early mortality.

RESULTS

The 30-day mortality rate was 7.5% (35/467). The most common causes of death were pneumonia (37.1%, 13/35), acute coronary syndrome (31.4%, 11/35) and sepsis (14.3%, 5/35). Surgery after 48 hours of admission had a significantly higher 30-day mortality rate (11 % versus 4%, p = 0.006). There was a significant difference in age (p = 0.034), admission source (p < 0.001), preoperative haemoglobin (p < 0.001), walking ability (p = 0.004), number of comorbidities (p = 0.004) and pre-existing dementia (p = 0.01), cardiac disease (p < 0.001), chronic obstructive pulmonary disorder (COPD) (p = 0.036) and renal failure (p = 0.007) between the 30-day mortality group and the rest of the cohort. Surgical delay greater than 48 hours, admission source and pre-existing cardiac disease were identified as the strongest predictors of 30-day mortality.

CONCLUSION

Surgical delay is an important but avoidable determinant of early mortality after HFS. Respiratory and cardiac function needs to be optimised postoperatively with early intervention in patients with signs of cardiovascular compromise or infection.

External validation of the discharge of hip fracture patients score

PURPOSE

This paper reports the external validation of a recently developed instrument, the Discharge of Hip fracture Patients score (DHP) that predicts discharge location on admission in patients living in their own home prior to hip fracture surgery.

METHODS

The DHP (maximum score 100 points) was applied to 125 hip fracture patients aged 50 or more years admitted to an academic centre in the northern part of The Netherlands (Groningen cohort). The characteristics of this cohort, sensitivity, specificity and positive and negative predictive value (PPV, NPV) of the DHP for discharge to an alternative location (DAL) were calculated and compared with the original cohort of hip fracture patients from the western part of The Netherlands (Delft cohort). Scoring 30 points or higher indicated DAL.

RESULTS

The Groningen cohort was younger compared to the Delft cohort, (mean age 75.4 vs. 78.5 years, P = 0.005) but was more often classified ASA III/IV (46.4% vs. 25.2%, P < 0.001). Sensitivity of the DHP for DAL in the Groningen cohort was 75% (vs. 83.8%), specificity of 66.7% (vs. 64.7%) and a PPV of 86.3% (vs. 79.2%), compared to the Delft cohort.

CONCLUSION

External validation of the DHP was successful; it predicted discharge location of hip fracture patients accurately in another Dutch cohort, the sensitivity for DAL was somewhat lower but the PPV higher. Therefore, the DHP score is a useful valid and easily applied instrument for general hip fracture populations.
