Early ambulation after hip fracture: effects on function and mortality

BACKGROUND: Few studies have examined the relationship between inpatient bed rest and functional outcomes. We examined how immobility is associated with function and mortality in patients with hip fracture. METHODS: We conducted a prospective cohort study of 532 patients 50 years and older, who were treated with surgery after hip fracture in 4 hospitals in New York. We collected information from hospital visits, medical records, and interviews. "Days of immobility" was defined as days until the patient moved out of bed beyond a chair. Follow-up was obtained on function (using the Functional Independence Measure) at 2 and 6 months and on survival at 6 months. RESULTS: Patients with hip fracture experienced an average of 5.2 days of immobility. Compared with patients with a longer duration of immobility (ie, at the 90th percentile) in adjusted analyses, patients at the 10th percentile of immobility had lower 6-month mortality (-5.4%; 95% confidence interval [CI], -10.9% to -1.0%) and better Functional Independence Measure score for locomotion (0.99 points; 95% CI, 0.3 to 1.7 points, with higher values indicating better function), but there was no significant difference in locomotion by 6 months (0.58 points; 95% CI, -0.3 to 1.4 points). The adverse association of immobility was strongest in patients using personal assistance or supervision with locomotion at baseline (difference in 6-month mortality between the 90th and 10th percentile of immobility was -17.1% [P = .004] for this group and only 1.2% [P = .38] for patients independent in locomotion at baseline). CONCLUSION: In patients with hip fracture, delay in getting the patient out of bed is associated with poor function at 2 months and worsened 6-month survival.     

Heterogeneity in hip fracture patients: age, functional status, and comorbidity

OBJECTIVES: To examine unidentified heterogeneity in hip fracture patients that may predict variation in functional outcomes. DESIGN: Observational, longitudinal, multisite cohort study. SETTING: Three separate cohorts from five hospitals in the metropolitan New York area and eight hospitals in Baltimore. PARTICIPANTS: Two thousand six hundred ninety-two hip fracture patients treated at one of 13 hospitals and followed for 6 months postfracture. MEASUREMENTS: A mobility measure with three categories (independent (walks independently or with a device), limited independence (needs human assistance or supervision to walk 150 feet or one block or able only to walk indoors), and unable to walk) was developed for use with all three cohorts. A similar measure was developed for the other activities of daily living (ADLs): bathing, dressing, feeding, and using the toilet. Cluster analysis was used to form homogenous groups of patients based on baseline demographic characteristics, comorbid conditions, and baseline mobility and ADL independence. RESULTS: Seven homogeneous subgroups were identified based on prefracture age, health, and functional status, with measurably different 6-month functional outcomes. At least 90% of patients could be correctly classified into the seven groups using simple decision rules about age, ADLs, and dementia status at baseline. Dementia was the only comorbid condition that segmented the groups. CONCLUSION: The heterogeneous hip fracture population can be grouped into homogenous patient clusters based on prefracture characteristics. Differentially targeting services and interventions to these subgroups may improve functional status outcomes.     

Mortality following hip fracture before and after implementation of the prospective payment system

Recent studies of patients with hip fractures from two hospitals have suggested that the marked reduction in length of stay that occurred following implementation of the Medicare prospective payment system (PPS) resulted in decreased quality of care for these patients. To assess whether this change influenced mortality, we studied patients with hip fractures aged 65 years or older from a 20% sample of Michigan Medicare enrollees. There were 2130 such patients in the 2 years preceding (October 1981 through September 1983) and 2238 in the 2 years following (October 1984 through September 1986) implementation of PPS. Although the demographic characteristics of patients with hip fractures did not change after PPS, the mean length of stay (95% confidence interval) decreased by 4.4 (4.1 to 4.7) days. However, mortality in the year following the fracture did not change: 23.2% before PPS, 23.7% after PPS; rate difference of 0.5% (-2.0 to 3.0). This finding was consistently present within subgroups defined by patient demographic characteristics. Furthermore, when the analysis was restricted to patients treated in those hospitals with the greatest reduction in average length of stay following PPS (7.5 days, or 35%), there was no significant change in 1-year mortality. For those patients who were enrolled in Medicaid and not in a nursing home at the time of the fracture, there was no increase in the rate of nursing home residence 1 year after the fracture. Thus, the findings of this population-based study suggest that the key outcomes of postfracture mortality and nursing home residence were not affected by the implementation of PPS.     

Patient relocation in the 6 months after hip fracture: risk factors for fragmented care

OBJECTIVES: To describe the incidence and patterns of patient relocation after hip fracture, identify factors associated with relocation, and examine effect of relocation on outcomes. DESIGN: Prospective cohort study. SETTING: Four hospitals in the New York metropolitan area. PARTICIPANTS: A total of 562 patients hospitalized for hip fracture discharged alive in 1997 to 1998. MEASUREMENTS: Patient characteristics and hospital course were ascertained using patient or surrogate interview, research nurse assessment, and medical record review. Patient location was ascertained at five time points using patient or surrogate interview, and hospital readmissions were identified using New York state and hospital admission databases. Mobility was measured using patient or surrogate report using the Functional Independence Measure. RESULTS: During 6 months of follow-up, the mean number of relocations per patient+/-standard deviation was 3.5+/-1.5 (range 2-10). Forty-one percent of relocations were between home and hospital, 36% between rehabilitation or nursing facility and hospital, 17% between rehabilitation or nursing facility and home, and 4% between two rehabilitation/nursing facilities. In a Poisson regression model that controlled for patient characteristics, hospital course, and length of follow-up, factors associated with relocation (P<.05) were absence of dementia, in-hospital delirium, one or more new impairments at hospital discharge, hospital discharge other than to home, and not living at home alone prefracture. Relocation was not significantly associated with immobility or mortality at 6 months (odds ratio=1.14, 95% confidence interval=0.97-1.35). CONCLUSION: Subgroups of patients with elevated risk of relocation after hip fracture may be target groups for intensive care coordination and care planning interventions.     

Physical therapy and mobility 2 and 6 months after hip fracture

OBJECTIVES: To examine the relationship between early physical therapy (PT), later therapy, and mobility 2 and 6 months after hip fracture. DESIGN: Prospective, multisite observational study. SETTING: Four hospitals in the New York City area. PARTICIPANTS: Four hundred forty-three hospitalized older patients discharged after surgery for hip fracture in 1997-98. MEASUREMENTS: Patient demographics, fracture type, comorbidities, dementia, number of new impairments at discharge, amount of PT between day of surgery and postoperative day (POD) 3, amount of therapy between POD4 and 8 weeks later, and prefracture, 2-, and 6-month mobility measured using the Functional Independence Measure. RESULTS: More PT immediately after hip fracture surgery was associated with significantly better locomotion 2 months later. Each additional session from the day of surgery through POD3 was associated with an increase of 0.4 points (P=.032) on the 14-point locomotion scale, but the positive relationship between early PT and mobility was attenuated by 6 months postfracture. There was no association between later therapy and 2- or 6-month mobility. CONCLUSION: PT immediately after hip fracture surgery is beneficial. The effects of later therapy on mobility were difficult to assess because of limitations of the data. Well-designed randomized, controlled trials of the effect of varying schedules and amounts of therapy on functional status after hip fracture would be informative.     

Functional recovery after hip fracture: the combined effects of depressive symptoms, cognitive impairment, and delirium

OBJECTIVES: To measure the prevalence of depressive symptoms, cognitive impairment, and delirium in patients with hip fracture and to estimate their effect on functional recovery, institutionalization, and death after surgical repair.
DESIGN: Prospective cohort.
SETTING: Hospital, follow-up to community and nursing home.
PARTICIPANTS: One hundred twenty-six patients aged 65 and older admitted for hip fracture repair.
MEASUREMENTS: Baseline measurements: Mini-Mental State Examination, Blessed Dementia Rating Scale, Geriatric Depression Scale, prefracture activities of daily living (ADLs), ambulatory status. The Confusion Assessment Method was used to diagnose in-hospital delirium. One- and 6-month outcomes were ADL decline, loss of ambulation, and new nursing home placement or death.
RESULTS: Twenty-two percent of patients had one cognitive or mood disorder, 30% had two, and 7% had three. At 1 month, each cognitive or mood disorder was independently associated with one or more adverse outcome. Considered together, each additional cognitive or mood disorder was associated with greater odds of 1 month outcomes (ADL decline: odds ratio (OR)=1.8, 95% confidence interval (CI)=1.1–2.9; decline in ambulation: OR=1.8, 95% CI=1.1–3.0; nursing home placement or death: OR=3.9, 95% CI=1.9–8.1).
CONCLUSION: Cognitive and mood disorders were common in elderly hip fracture patients and were associated with greater risk of poor outcomes, both independently and in combination. Recognition and treatment of these conditions may reduce adverse outcomes in this vulnerable population.     

The course of delirium in older medical inpatients

OBJECTIVES: To describe the clinical course and outcomes of delirium up to 12 months after diagnosis, the relationship between the in-hospital clinical course and post-discharge outcomes, and the role of dementia in both the clinical course and outcomes of delirium. DESIGN: Prospective cohort study. SETTING: Medical wards of a 400-bed, university-affiliated, primary acute care hospital in Montreal. PATIENTS: Cohort of 193 medical inpatients aged 65 and over with delirium diagnosed at admission or during the first week in hospital, who were discharged alive from hospital. MEASUREMENTS AND MAIN RESULTS: Study outcomes included cognitive impairment and activities of daily living (standardized, face-to-face clinical instruments at 1-, 2-, 6-, and 12-month follow-up), and mortality. Dementia, severity of illness, comorbidity, and sociodemographic variables were measured at time of diagnosis. Several measures of the in-hospital course of delirium were constructed. The mean numbers of symptoms of delirium at diagnosis and 12-month follow-up, respectively, were 4.5 and 3.5 in the subgroup of patients with dementia and 3.4 and 2.2 among those without dementia. Inattention, disorientation, and impaired memory were the most persistent symptoms in both subgroups. In multivariate analyses, pre-morbid and admission level of function, nursing home residence, and slower recovery during the initial hospitalization were associated with worse cognitive and functional outcomes but not mortality. CONCLUSIONS: Among patients with and without dementia, symptoms of delirium persist up to 12 months after diagnosis. Quicker in-hospital recovery is associated with better outcomes.     

Die Kosten hüftgelenksnaher Frakturen in Deutschland: Eine prospektive Untersuchung

OBJECTIVE: To assess the direct and indirect costs of hip fracture in dependence of postoperative care setting. STUDY DESIGN: Prospective cohort study. METHODS: 227 consecutive patients in three hospitals (city, town, and small town) presenting with hip fracture. For 177 patients there was follow-up regarding post-operative care-setting. During follow-up the cost of the remaining patient at 1, 3, 6 month were recorded and afterwards adjusted to the distribution of the initial cohort. To obtain information on patient characteristics, assessment during hospital stay and follow up have been performed. RESULTS: There was a relevant difference in costs depending on the care setting after hip fracture. The nursing home - nursing home, community - community, and community - nursing home resulted in total costs at 6 month of 17,701 DM, 27,102 DM and 54, 503 DM, respectively (average: 24,508 DM). Nursing home costs contributed significantly to the differences between groups. Valid and predictive measures could not be established in first analysis of performed assessments. CONCLUSION: Due to the high incidence of hip fractures (100,000/y) indirect costs play a major role in the economic impact of this illness. The analysis of the effectiveness of interventions has to take into account these costs to achieve adequate conclusions.     

Delirium severity and psychomotor types: their relationship with outcomes after hip fracture repair

OBJECTIVES: To validate the Memorial Delirium Assessment Scale (MDAS) as a measure of delirium severity in a cohort of patients aged 65 and older; to examine the association between severity of delirium and patient outcomes; and to examine the association between psychomotor variants of delirium and each of those outcomes. DESIGN: Prospective assessment of sample. SETTING: Hospital. PARTICIPANTS: One hundred twenty-two older patients (mean age +/- standard deviation = 79 +/- 8) who had undergone acute hip fracture surgery. MEASUREMENTS: We used standardized instruments to assess prefracture activities of daily living (ADLs), ambulatory status, cognition, and living situation. Postoperatively, each patient was interviewed daily. Delirium was diagnosed using the Confusion Assessment Method (CAM), and delirium severity was measured using the MDAS. The MDAS was also used to categorize the psychomotor types of delirium into "purely hypoactive" or "any hyperactivity." Telephone or face-to-face interviews were conducted at 1 and 6 months to assess survival, ADL function, ambulatory status, and living situation. RESULTS: Of 122 patients, 40% developed CAM-defined delirium. Delirious patients had higher average MDAS scores than nondelirious patients (11.7 vs 2.4, P <.0001). We used the median of the average MDAS score to classify patients into mild or severe delirium. Severe delirium was generally associated with worse outcomes than was mild delirium, and the associations reached statistical significance for nursing home placement or death at 6 months (52% vs 17%, P =.009). Additionally, patients who did not meet full CAM criteria for delirium experienced worse outcomes if they had some symptoms of delirium than if they had no or few symptoms (nursing home placement or death at 6 months: 27% vs 0%, P =.001). Surprisingly, these patients with subsyndromal delirium who did not fulfill CAM criteria for delirium but demonstrated significant delirium symptoms, had outcomes similar to or worse than those with mild CAM-defined delirium. Pure hypoactive delirium accounted for 71% (34/48) of cases and was less severe than was delirium with any hyperactivity (average MDAS score 10.6 vs 14.8, P =.007). In our cohort, patients with pure hypoactive delirium had better outcomes than did those with any hyperactivity (nursing home placement or death at 1 month: 32% vs 79%, P =.003); this difference persisted after adjusting for severity. CONCLUSION: In this study of delirium in older hip fracture patients, the MDAS, a continuous severity measure, was a useful adjunct to the CAM, a dichotomous diagnostic measure. In patients with CAM-defined delirium, severe delirium was generally associated with worse outcomes than was mild delirium. In patients who did not fulfill CAM criteria, subsyndromal delirium was associated with worse outcomes than having few or no symptoms of delirium. Patients with subsyndromal delirium had outcomes similar to patients with mild delirium, suggesting that a dichotomous approach to diagnosis and management may be inappropriate. Pure hypoactive delirium was more common than delirium with any hyperactive features, tended to be milder, and was associated with better outcomes even after adjusting for severity. Future studies should confirm our preliminary associations and examine whether treatment to reduce the severity of delirium symptoms can improve outcomes after hip fracture repair.     

Delirium is independently associated with poor functional recovery after hip fracture

OBJECTIVE: To evaluate the role of delirium in the natural history of functional recovery after hip fracture surgery, independent of prefracture status. DESIGN: Prospective cohort study. SETTING: Orthopedic surgery service at a large academic tertiary hospital, with follow-up extending into rehabilitation hospitals, nursing homes, and the community. PARTICIPANTS: One hundred twenty-six consenting subjects older than 65 years (mean age 79 +/- 8 years, 79% women) admitted emergently for surgical repair of hip fracture. MEASUREMENTS: Detailed assessment at enrollment to ascertain prefracture status through interviews with the patient and designated proxy and review of the medical record. Interviews included administration of standardized instruments (Activities of Daily Living (ADL) Scale, Blessed Dementia Rating Scale, Delirium Symptom Interview) and assessment of ambulation, and prefracture living situation. Medical comorbidity, the nature of the hip fracture, and the surgical repair were obtained from the medical record. All subjects underwent daily interviews for the duration of the hospitalization, including the Mini-Mental State Examination and Delirium Symptom Interview, and delirium was diagnosed using the Confusion Assessment Methods algorithm. Patients and proxies were recontacted 1 and 6 months after fracture, and underwent interviews similar to those at enrollment to determine death, persistent delirium, decline in ADL function, decline in ambulation, or new nursing home placement. RESULTS: Delirium occurred in 52/126 (41%) of patients, and persisted in 20/52 (39%) at hospital discharge, 15/52 (32%) at 1 month, and 3/52 (6%) at 6 months. Patients aged 80 years or older, and those with prefracture cognitive impairment, ADL functional impairment, and high medical comorbidity were more likely to develop delirium. However, after adjusting for these factors, delirium was still significantly associated with outcomes indicative of poor functional recovery 1 month after hip fracture: ADL decline (odds ratio (OR) = 2.6; 95% confidence interval (95% CI), 1.1- 6.1), decline in ambulation (OR = 2.6; 95% CI, 1.03-6.5), and death or new nursing home placement (OR = 3.0; 95% CI, 1.1-8.4). Patients whose delirium persisted at 1 month had worse outcomes than those whose delirium had resolved. CONCLUSIONS: Delirium is common, persistent, and independently associated with poor functional recovery 1 month after hip fracture even after adjusting for prefracture frailty. Further research is necessary to identify the mechanisms by which delirium contributes to poor functional recovery, and to determine whether interventions designed to prevent or reduce delirium can improve recovery after hip fracture.     

Summarizing amount of difficulty in ADLs: a refined characterization of disability. Results from the women's health and aging study

Activities of Daily Living (ADLs) rating scales often classify older persons as independent or dependent in self-care activities. However, with this type of classification system little information is available on people who, while not dependent, do report some difficulty in performing self-care activities. This 3-year prospective cohort study presents an ADL summary scale that assesses a gradient of difficulty in ADLs for moderately to severely disabled women aged 65 and older living in the Baltimore, Maryland area. At baseline and for each of six interviews done at 6-month intervals, an ADL summary score measuring ADL difficulty was created. ADL summary score slopes were created for each woman who completed at least the baseline and first three follow-up interviews. The baseline ADL summary score and slope of the ADL summary score were used to predict risk of future hospitalization, nursing home admission and death. Additionally, 6-month ADL summary change scores were calculated in order to assess change in the ADL summary score for women who did and did not report an acute event (MI, stroke or hip fracture) at follow-up. The ADL summary scale showed excellent reliability. Intraclass correlation coefficients ranged from 0.83 to 0.93 for measures made one week apart. The 6-month average correlation coefficient was 0.77. The ADL summary scale also performed well in tests of validity. Poorer scores on the ADL summary scale were significantly and inversely related to an objective physical performance scale. The baseline ADL summary score and slope of the ADL summary score predicted future risk of hospitalization, nursing home admission and death. Each unit increase in the slope of the ADL summary score was associated with a 19% (95% CI 1.10, 1.29) increased risk of hospitalization, a 57% (95% CI 1.37, 1.81) increased risk of nursing home admission and a 41% (95% CI 1.22, 1.64) increased risk of death, adjusting for potential confounders. The mean 6-month ADL change score for women reporting an acute event (2.59) was significantly different from those not reporting an acute event (0.52). The strongest and most significant mean 6-month ADL change score was observed for women who reported a hip fracture (4.52) followed by stroke (2.40) and MI (1.00). These results demonstrate that the ADL summary scale presented has validity, reliability and is sensitive to change. This scale, therefore, offers the opportunity to classify functional problems in a larger proportion of the population than do ADL dependence scales. Additionally, it gives us a way to identify earlier functional changes, and a way to track the natural history of functional problems as well as a response to interventions.     

Impact of prospective payment and discharge location on the outcome of hip fracture

OBJECTIVE: To determine the impact of prospective payment by diagnosis-related groups (DRGs) on length of stay in the hospital, ambulatory status, and level of post-hospital care needed for patients hospitalized with hip fracture. DESIGN: Retrospective chart review of a consecutive series of cases before and after the reference date of implementation of the prospective payment system (PPS). SETTING: Academic, tertiary-care hospital. PATIENTS/PARTICIPANTS: 181 patients 69 years of age or older admitted with International Classification of Diseases (ICD) or DRG codes for hip fracture. RESULTS: Length of stay was shorter by 1.37 days in the post-PPS era (p = 0.05). Poorer discharge ambulation was found in the post-PPS group (p = 0.089). At one year, differences in ambulation and nursing home residence were found to be related not to the implementation of PPS, but rather to the nursing home to which the patient was discharged. Patients discharged to a facility with active physical rehabilitation were less likely to remain institutionalized (p = 0.0025) than those in "ordinary" nursing homes and ambulated more independently (p = 0.05). CONCLUSIONS: The PPS did not have a significant long-term impact on hip fracture outcome. Post-hospital care may be of crucial importance to the future quality of life of hip fracture patients.     

Effect of fracture on the health care use of nursing home residents

BACKGROUND: Osteoporotic fractures result in increased health care use. Care following fracture has been characterized for community dwellers but not for nursing home residents, whose fracture rates are as much as 11 times higher than those of age-matched community dwellers. Knowing the amount of care following fracture may help determine the effects of fracture prevention on use and costs in this population. METHODS: A prospective cohort study was conducted, with 18 months of follow-up, of 1427 randomly selected white, female nursing home residents 65 years and older from 47 randomly selected nursing homes in Maryland. RESULTS: After controlling for age, comorbidities, and mobility, nursing home residents who experienced a fracture were hospitalized more than 15 times as often as those who did not in the month following the fracture (relative rate, 15.35; 95% confidence interval, 12.27-19.21) and at a higher rate from 3 through 12 months postfracture. Rates in the first month were higher for persons with a hip fracture (relative rate, 31.01; 95% confidence interval, 26.52-36.24). Rates of emergency department use and contacts with physicians and therapists were increased, the latter two for 12 months following fracture. Also, before the fracture, patients who experienced a fracture visited the emergency department and had more physician contacts; for those with a hip fracture, there were fewer prefracture hospitalizations. CONCLUSIONS: Health care use remained elevated through 1 year postfracture. Comparisons with community patients suggest that this care may be less than what would be provided in other settings. For patients who fractured a hip, higher use decreased after 6 months, similar to community cohorts. Nursing home residents who visit the emergency department may warrant special screening for a fracture.     

Factors associated with short- versus long-term skilled nursing facility placement among community-living hip fracture patients

Characteristics associated with long-term placement among community-living patients admitted to a skilled nursing facility (SNF) after a hip fracture were identified. Subjects were 151 consecutive, elderly, community-living persons discharged from two acute hospitals to SNFs after surgery for a hip fracture. Medical, functional, psychological, social, and outcome data were collected from hospital and nursing home charts. Ninety-seven subjects (64%) were discharged home within 6 months; 50 (33%) became permanent SNF residents; and four died. Multiple logistic regression identified orientation, younger age, ability to bathe independently, family involvement, ability to ambulate or transfer independently, and greater number of available physical therapy hours as factors contributing independently to returning home. Likelihood of returning home increased from 7% among subjects with fewer than two of the patient characteristics to 82% among subjects with four or more characteristics (P less than .0005). These results suggest that hip fracture patients at high risk of permanent SNF placement can be identified at time of hospital discharge. Investigations are needed to determine whether more intensive rehabilitation and discharge planning may improve the chance of returning home for a large percent of hip fracture patients.     

Undernourished Patients With Hip Fracture: Poor Outcome is Not Due to Excess Infections

Background : Undernourished hip fracture patients have poorer outcomes for undetermined reasons. We postulated that an immune deficit from malnutrition could lead to excess infections in these patients. Objective : To document the nutritional status (body mass index, BMI), infection rates and outcome in a group of patients with hip fracture. Subjects : One hundred consecutive cases, after excluding nursing home residents and those with end-stage or malignant disease. Results : Low BMI was common and was associated with greater age, presence of dementia and falling indoors. Patients with low BMI had significantly poorer functional outcomes, greater mortality and nursing home admission rates. Infections were not more common in those with low BMI. An apparent association between poor outcome and the presence of infection in those with low BMI was not confirmed by multiple logistic regression analysis. Conclusions : Significant undernutrition was common and was associated with poorer outcomes in patients with hip fracture. This did not appear to be due to either an excess of infections or an adverse response to infection.     

The association of race, gender, and comorbidity with mortality and function after hip fracture

BACKGROUND: Few studies of hip fracture have large enough samples of men, minorities, and persons with specific comorbidities to examine differences in their mortality and functional outcomes. To address this problem, we combined three cohorts of hip fracture patients to produce a sample of 2692 patients followed for 6 months. Method. Data on mortality, mobility, and other activities of daily living (ADLs) were available from all three cohorts. We used multiple regression to examine the association of race, gender, and comorbidity with 6-month survival and function, controlling for prefracture mobility and ADLs, age, fracture type, cohort, and admission year. RESULTS: The mortality rate at 6 months was 12%: 9% for women and 19% for men. Whites and women were more likely than were nonwhites and men to survive to 6 months, after adjusting for age, comorbidities, and prefracture mobility and function. Whites were more likely than were nonwhites to walk independently or with help at 6 months compared to not walking, after adjusting for age, comorbidities, and prefracture mobility and function. Dementia had a negative impact on survival, mobility, and ADLs at 6 months. The odds of survival to 6 months were significantly lower for people with chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), and/or cancer. Parkinson's disease and stroke had negative impacts on mobility and ADLs, respectively, among survivors at 6 months. CONCLUSIONS: The finding of higher mortality and worse mobility for nonwhite patients with hip fractures highlights the need for more research on race/ethnicity disparities in hip fracture care.     

Subsequent fracture in nursing home residents with a hip fracture: a competing risks approach

OBJECTIVES: To determine the incidence and predictors of subsequent fracture in nursing home residents with a hip fracture, accounting for the competing risk of death. DESIGN: Dynamic cohort study. SETTING: Hebrew Rehabilitation Center, a 725‐bed, long‐term care facility in Boston, Massachusetts. PARTICIPANTS: Long‐term care residents with a surgically repaired hip fracture (1999–2006) followed through June 30, 2007, for the occurrence of subsequent fracture at any skeletal site. MEASUREMENTS: Information on age, sex, anatomic location, type of repair, body mass index (BMI), comorbidities, functional status, cognitive status, and medication use were evaluated as potential risk factors for subsequent fracture. RESULTS: The study included 184 residents with a baseline hip fracture. Thirty‐nine residents (7 men, 32 women) experienced a subsequent fracture over a median follow‐up of 1.1 years. After the baseline hip fracture, 6% of residents experienced a subsequent fracture within 6 months, 12% within 1 year, and 21% within 5 years. In addition, 23% of residents died within 6 months, 31% within 1 year, and 60% within 5 years. High functional status was associated with a five times greater risk of subsequent fracture (high vs low functional status, hazard ratio=5.10, P<.005). Age, sex, BMI, comorbidities, cognitive status, and medication use were not associated with subsequent fracture. CONCLUSION: Hip fractures are a sentinel event in nursing home residents, with a high incidence of subsequent fracture and death occurring within 1 year. Identification of prefracture characteristics and postfracture complications associated with mortality should help guide secondary prevention efforts in nursing home residents.     

Interdisciplinary intervention for hip fracture in older Taiwanese: benefits last for 1 year

BACKGROUND: Little is known about the effects of interventions for elderly patients with hip fracture in Asian countries, particularly beyond the short term. METHODS: Outcomes (service utilization, clinical outcomes, self-care ability, and depressive symptoms) were assessed at 1, 3, 6, and 12 months after discharge. Self-care ability (ability to perform activities of daily living [ADLs]), was measured by the Chinese Barthel Index. Depressive symptoms were measured by the Chinese Geriatric Depression Scale, short form. RESULTS: The experimental group (n = 80) had a significantly better ADL trajectory than the control group (n = 82) during the 1st year after discharge (p =.002). More participants in the experimental group than in the control group recovered their previous walking ability both at 6 months (81% vs 58%, respectively) and 12 months (84% vs 66%, respectively) after discharge. Overall, the odds ratio for the experimental group recovering their previous walking ability was 2.72 (p <.001) compared to the control group. The experimental group had significantly fewer depressive symptoms than the control group during the 1st year following discharge (p =.004). CONCLUSION: An interdisciplinary intervention for hip fracture with a discharge support component benefited elderly persons with hip fracture by improving both self-care ability and walking ability, and by decreasing depressive symptoms during the 1st year after hospital discharge.     

Effect of an inpatient geriatric consultation team on functional outcome, mortality, institutionalization, and readmission rate in older adults with hip fracture: a controlled trial

OBJECTIVES: To evaluate the effect of an inpatient geriatric consultation team (IGCT) on end points of interest in people with hip fracture: length of stay, functional status, mortality, new nursing home admission, and hospital readmission. DESIGN: Controlled trial based on assignment by convenience. SETTING: Trauma ward in a university hospital. PARTICIPANTS: One hundred seventy‐one people with hip fracture aged 65 and older. INTERVENTION: Participants were assigned to a multidisciplinary geriatric intervention (n=94) or usual care (n=77) during hospitalization after hip fracture. MEASUREMENTS: End points were functional status, length of stay, mortality, new nursing home admission, and hospital readmission 6 weeks, 4 months, and 12 months after surgery. RESULTS: Mean length of stay was 11.1 ± 5.1 days in the intervention group and 12.4 ± 8.5 days in the control groups (P=.24). Complete adherence to IGCT recommendations was 56.8%. A significant benefit of intervention on functional status in univariate analyses (P=.02) 8 days after surgery disappeared in a linear mixed model. Participants with dementia had better functional status in a linear mixed model than those without (P=.03), but this effect was no longer significant after Bonferroni correction for multiple testing. After 6 weeks, 4 months, and 12 months, no between‐group differences could be documented for mortality, new nursing home admission, or readmission rate. CONCLUSION: This trial could not document functional benefits of an IGCT intervention in people with hip fracture. More research is needed to investigate whether a more‐intensive approach with more‐direct control over patient management, more‐specific recommendations, and more‐intense education would be effective.     

A cost-benefit analysis of external hip protectors in the nursing home setting

OBJECTIVES: To estimate potential cost savings generated by a program of hip protectors in the nursing home from a Medicare perspective. DESIGN: A state-transition Markov model considering short-term and long-term outcomes of hip protectors for a hypothetical nursing home population, stratified by age, sex, and functional status. Costs, transition probabilities between health states, and estimates of hip protectors' effectiveness were derived from published secondary data. SETTING: Nursing home facilities in the United States. PARTICIPANTS: Hypothetical cohort of permanent nursing home residents aged 65 and older without a previous hip fracture. INTERVENTION: Program of hip protectors reimbursed by Medicare. MEASUREMENTS: Number of fractures, life years, and dollars saved. RESULTS: Three pairs of hip protectors replaced annually would result in a weighted average lifetime absolute risk reduction for hip fracture of 8.5%, with net lifetime savings to Medicare of 223 dollars per resident. When the annual cost of hip protectors is less than 151 dollars per person, relative risk of fracture is less than or equal to 0.65 with hip protectors, or adherence is greater than 42%, hip protectors are cost saving to Medicare over a wide range of assumptions. Extrapolating these results to the estimated population of U.S. nursing home residents without a previous hip fracture, Medicare could save 136 million dollars in the first year of a hip-protector reimbursement program. CONCLUSION: From a Medicare perspective, hip protectors are a cost-saving intervention in the nursing home setting when hip protector effectiveness is less than or equal to 0.65 over the remaining lifetime of subjects.
