OBJECTIVES: To examine the prevalence, incidence, persistence, predictors, and outcomes of cognitive impairment after hip fracture. DESIGN: Longitudinal cohort study. SETTING: Eight hospitals in Baltimore, Maryland. PARTICIPANTS: Six hundred seventy-four hip fracture patients aged 65 and older living in the community before fracture. MEASUREMENT: Delirium at admission and postsurgery, Mini-Mental State Examination (MMSE) scores postsurgery, and prefracture proxy ratings of MMSE and dementia. Follow-up measures at 2 and 12 months postfracture included mortality, MMSE, physical activities of daily living (PADLs), instrumental activities of daily living (IADLs), social functioning, and the Center for Epidemiologic Studies-Depression Scale. RESULTS: Overall, 28% had prefracture dementia or MMSE impairment, 8% had cognitive impairment first detected presurgery, 14% had impairment first detected postsurgery, and 50% were not impaired before or during hospitalization. Incident cognitive impairment was more likely in patients who were older, male, and less educated and had more prefracture PADL impairment, intertrochanteric fractures, and higher anesthesia risk ratings. Presurgery incident cases did not differ significantly from those detected postsurgery in functional outcomes or in persistence of cognitive impairment. Cognitive impairment first noted in the hospital persisted through 2 and 12 months in more than 40% of patients. Those with cognitive impairment persisting through 2 months had poorer 12-month PADLs and social functioning. CONCLUSION: Prefracture cognitive impairment and incident cognitive impairment during hospitalization are risk factors for poor functional outcomes. Many incident cognitive problems persisted over 2 to 12 months, and per-sistence predicted later functional and social impairment.  相似文献

BACKGROUND: It is largely unknown whether functional recovery following hip fracture differs between long-term care (LTC) and community-dwelling residents. Our primary purpose was to compare recovery between these patients 6 months following hip fracture, controlling for known prognostic factors. Secondarily, we examined the contribution of residential status, in addition to patient characteristics, to functional recovery. METHODS: We studied a population-based inception cohort of 451 hip fracture patients >/= 65 years old admitted to one Canadian health region hospital between July 1999 and September 2000. Participants completed the Modified Barthel Functional Index (MBI) in hospital and again via telephone interviews 6 months postoperatively. Data were also collected on surgery and rehabilitation timing, length of hospital stay (LOS). and discharge destination. Relative change from prefracture function adjusting for known prognostic factors, and the proportion of participants returning to prefracture function were compared between the LTC and community-dwelling residents. RESULTS: LTC residents (n = 115) were older, with lower function prefracture, more comorbidities, and increased dementia than community-dwelling residents (n = 336). Six months postfracture, 17 (22%) LTC and 180 (71%) community-dwelling residents had regained prefracture function (p <.001). LTC residents had 33% lower (-40.6, -27.2) and community-dwelling residents 11.6% lower (-14.8, -8.4) 6-month MBI scores relative to prefracture scores after risk adjustment. Residential status was significantly associated with risk-adjusted functional recovery (p <.001). Median LOS was 4 days less for LTC than for community-dwelling residents (p <.001). Twelve (10%) LTC and 266 (79%) community-dwelling residents were discharged to inpatient rehabilitation (p <.001). CONCLUSION: Following hip fracture, most LTC residents do not regain prefracture function irrespective of known prognostic factors. Further investigation is needed as to the extent to which personal and environmental characteristics contribute to outcome after hip fracture.  相似文献

BACKGROUND: Hip fracture patients are at increased risk of confusion or delirium due to the trauma associated with the injury and the rapid progression to hospitalization and surgery, in addition to the pain and loss of function experienced. Hip fracture patients who develop delirium may require longer hospital stays, are more often discharged to long-term care, and have a generally poor prognosis for returning home or regaining function in activities of daily living (ADL). METHODS: The present study examines the impact of delirium present on hospital admission in a sample of 682 non-demented, aged hip fracture patients residing in the community at the time of their fracture. In-hospital assessments designed to assess both prefracture and postfracture functioning, as well as follow-up interviews at 2, 6, 12, 18, and 24 months postfracture, were obtained from participants. RESULTS: Analyses indicate that baseline or admission delirium is an important prognostic predictor of poor long-term outcomes in persons without known cognitive impairment, after controlling for age, gender, race, comorbidity, and functional status. Delirium at admission (i.e., prior to surgery) was associated with poorer functioning in physical, cognitive, and affective domains at 6 months postfracture and slower rates of recovery. Impairment and delays in recovery may be further exacerbated by increased depressive symptoms in confused patients over time. Delirium on hospital admission was not a significant predictor of mortality after adjustment for confounding factors. CONCLUSIONS: The present findings further emphasize the significance of immediate detection and treatment of delirium in hip fracture patients to ameliorate the short and long-term effects of acute confusion on functional outcomes.  相似文献

OBJECTIVES. Identify determinants of health decline associated with hip fracture with the goal of designing interventions. METHOD. Prefracture and postfracture information was obtained from participants aged 65-plus years fracturing a hip between July 1996 and August 1997. Health utilization data were linked to the cohort data and to an age-gender matched cohort of nonfracture seniors. RESULTS. Fracture patients were likely to have been hospitalized and have low continuity of care. Patients making frequent physician visits were at increased risk of both prefracture hospitalization and postfracture health decline. Prefracture hospitalization was less likely for patients with high physical function; patients of high mental status were less likely to experience postfracture health decline. DISCUSSION. Health appears to be in decline prefracture. Patients may benefit from continuous physician care to prevent further health deterioration. Some hip fractures can be prevented by identifying high-risk seniors at an early stage and intervening to prevent falls.  相似文献

OBJECTIVES: To assess 2-year excess mortality or institutionalization risk associated with hip fracture in community-dwelling people aged 60 and over. DESIGN: Cohort study. SETTING: Auckland, New Zealand, from July 1991 to February 1996. PARTICIPANTS: Five hundred sixty-five community-dwelling older people recently hospitalized with a hip fracture and 782 randomly selected controls, frequency matched for age and gender, living in the same catchment area as the cases. MEASUREMENTS: Two-year mortality or institutionalization status. RESULTS: Over half (52.1%) of male hip fracture cases and 12.4% of male controls were dead or institutionalized, compared with 39.2% of female hip fracture cases and 19.7% of female controls. The odds ratio, adjusted for baseline demographic characteristics, medical status, and physical function, for death or institutionalization was 6.89 (95% confidence interval (CI) = 2.75-17.27) for men and 1.48 (95% CI = 1.02-2.19) for women. CONCLUSIONS: For both men and women who incur a hip fracture, the risks of dying or being institutionalized within 2 years are higher than for their peers. The independent effect of hip fracture on this outcome was significantly greater for men than women. The marked influences of prefracture health status, physical limitations, and gender on outcome have important implications for preventative strategies.  相似文献

PurposeAlthough a second hip fracture is not uncommon in the older population, the extent to which such an event may affect health-related outcomes has not been fully clarified. We aimed to evaluate the risk of new falls, functional decline, rehospitalization, institutionalization and mortality in older patients admitted for a second vs. a first hip fracture.MethodsThe sample consisted of 288 older patients admitted to the Orthogeriatric Unit of Bolzano Hospital (northern Italy) and surgically treated for a hip fracture from June 2016 to June 2017. Socio-demographic data and hospitalization-related information were collected and a multidimensional assessment was made upon admission and during the hospital stay. Fifteen months after discharge, data on mobility level, functional status, institutionalization, and new falls were obtained from personal or structured phone interviews. Information on rehospitalization and mortality was obtained from local hospital registers.ResultsOne out of six patients (14.6 %) admitted was suffering a second hip fracture, of which only 16.7 % were on antiresorptive therapies. At the 15-month follow-up, individuals who had been treated for a second hip fracture were more likely than those treated for their first to have low mobility levels (OR = 4.13, 95 %CI:1.23−13.84), to be rehospitalized (OR = 2.57, 95 %CI:1.12−5.90), and to have a higher mortality (HR = 1.81, 95 %CI:1.05–3.12).ConclusionsThe occurrence of a second hip fracture may further affect the clinical vulnerability and mortality of older adults. These results highlight the need to implement preventive action to minimize the risk of re-fracture after the first event.  相似文献

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.  相似文献

BACKGROUND: More than 220,000 persons 65 years and older fracture a hip every year in the United States. Although hip fractures have been considered as a single, homogeneous condition, there are two major anatomic types of proximal femoral fractures: intertrochanteric and femoral neck. The present study's objective was to determine if the two types of hip fracture have different patient characteristics and sequelae. METHODS: A prospective study of 923 elderly patients admitted to seven Baltimore hospitals for a hip fracture between 1984 and 1986. RESULTS: Patients with intertrochanteric fractures were slightly older, sicker on hospital admission, had longer hospital stays, and were less likely at 2 months postfracture to have recovered activities of daily living than femoral neck fracture patients. Intertrochanteric fracture patients also had higher mortality rates at 2 and 6 months after fracturing. Long-term recovery (1 year) did not differ between fracture type. CONCLUSIONS: It appears that intertrochanteric fracture patients have intrinsic factors (older age, poor health) impacting upon their risk of fracture and ability to recover. Differences in patient characteristics and sequelae do exist between femoral neck and intertrochanteric hip fracture patients that impact upon recovery.  相似文献

OBJECTIVES: To assess whether the occurrence of a hip fracture is associated with an increased risk of mortality even after taking into account age and prefracture health status and whether this increased risk of mortality persists beyond the first 6 months after the fracture. DESIGN: A prospective study of risk factors for hip fracture. SETTING: Five French areas: Amiens, Lyon, Montpellier, Paris, and Toulouse. PARTICIPANTS: The cohort consisted of 7,512 volunteer ambulatory women aged 75 and older who were recruited from voter registration lists. Women who had a history of hip fracture or bilateral hip replacement were excluded. MEASUREMENTS: The baseline examination included a functional and clinical examination and a questionnaire on life style and treatments. Thereafter, women were followed every 4 months for 4 years to record the occurrence of fractures and deaths. A multivariable proportional hazards model was used to determine the association between hip fracture (treated as a time-dependent variable) and mortality, after adjustment for age and baseline health status. RESULTS: During a mean+/-standard deviation follow-up of 3.9+/-0.9 years, 338 women had a first hip fracture, and their postfracture mortality rate was 112.4 per 1,000 woman-years, compared with 27.3 per 1,000 woman-years for the 6,115 women who did not have any fracture (P<.001). After adjusting for age and baseline health status, women with hip fracture were more than twice as likely to die (95% confidence interval (CI)=1.6-2.8). This increased risk appeared more pronounced in the first 6 months (relative risk (RR)=3.0, 95% CI=1.9-4.7) than after (RR=1.9, 95% CI=1.6-2.2) (P=.09). CONCLUSION: In ambulatory elderly women, the occurrence of a hip fracture is associated with an increased risk of death, even after prefracture health status is taken into account. Although the effect of the fracture is stronger in the first 6 months, it persists for several years thereafter, which suggests that prevention of hip fracture and improved care after the fracture may contribute to increase life expectancy in addition to preserving quality of life.  相似文献

BACKGROUND: Hip fracture is a significant health problem for men and women; between 25 and 30 percent of all hip fractures are sustained by men. Relatively little is known about gender differences in functional outcomes after hip fracture. The purpose of the current study is to compare post-hip fracture functional recovery of men and women. METHODS: A sample of 674 patients age 65 or older were recruited as part of the Baltimore Hip Studies and were followed longitudinally for 1 year following fracture. Information on prefracture status and hospital course of treatment was collected as well as functional data at baseline, 2, 6, and 12 months postfracture. Data were analyzed longitudinally using Generalized Estimating Equations (GEEs). RESULTS: Men in the study were generally younger and suffered greater comorbidity at time of fracture. Men further suffered higher mortality in the year following fracture. Among survivors, little difference between men and women was seen in patterns of recovery of function following fracture. CONCLUSIONS: Hip fracture is not a problem affecting just women. Recovery following fracture for men is probably no better than that for women, even after mortality differentially eliminates the frailest male participants. However, psychosocial factors, greater comorbidity, and higher rates of certain complications among men may require adjustments to interventions designed to restore function. Further research into the consequences of hip fracture for men and women is needed.  相似文献

OBJECTIVES: To present several alternative approaches to describing the range and functional outcomes of patients with hip fracture. DESIGN: Prospective study with concurrent medical records data collection and patient and proxy interviews at the time of hospitalization and 6 months later. SETTING: Four hospitals in the New York metropolitan area. PARTICIPANTS: Five hundred seventy-one hospitalized adults aged 50 and older with hip fracture between July 1997 and August 1998. MEASUREMENTS: Rates of return to function in four physical domains, mortality, and nursing home residence at 6 months. Cluster analysis was used to describe the heterogeneity among the sample and identify variations in 6-month mortality, nursing home residence, and level of functioning and to develop a patient classification tree with associated patient outcomes at 6 months postfracture. RESULTS: In locomotion, transfers, and self-care, 33% to 37% of patients returned to their prior level of function by 6 months, including those needing assistance, but only 24% were independent in locomotion at 6 months. Cluster analysis identified eight patient subgroups that had distinct baseline features and variable outcomes at 6 months. The patient classification tree used four variables: atypical functional status (independent in locomotion but dependent in other domains); nursing home residence; independence/dependence in self-care; and age younger than 85 or 85 and older that identified five subgroups with variable 6-month outcomes that clinicians may use to predict likely outcomes for their patients. CONCLUSION: Patients with hip fracture are heterogeneous with respect to baseline and outcome characteristics. Clinicians may be better able to give patients and caregivers information on expected outcomes based on presenting characteristics used in the classification tree.  相似文献

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.  相似文献

BACKGROUND: Prefracture physical function must be accurately determined to set appropriate and attainable goals for rehabilitation following hip fracture. This is especially important for people who were living independently prior to their fracture. This study determines reliability and internal consistency of a prefracture physical function questionnaire (PFPFQ) completed by both patients and knowledgeable informants (KIs). METHODS: A 20-item PFPFQ, including ambulation, transfers, balance, and self-care domains, was developed using focus groups. Community-dwelling patients with a hip fracture (N = 40, 77.9 +/- 8 years) completed the PFPFQ on two occasions during postoperative acute care. Forty KIs were identified by the patients and also completed the PFPFQ on two occasions via telephone interview. Day-to-day reliability of the patients and KIs [intraclass correlation coefficients (ICC)], and internal consistency [Kuder-Richardson coefficient (KR)] of the PFPFQ were determined. RESULTS: Intrarater reliability was high with ICCs (95% confidence interval) of 0.94 (0.89, 0.96) for patients and 0.96 (0.93, 0.98) for KIs. Interrater reliability on occasion 1 had an ICC of 0.81 (0.69, 0.88). Internal consistency of the patient responses on the first occasion was high (KR coefficient = 0.896). CONCLUSIONS: The PFPFQ is a reliable and internally consistent instrument for determining prefracture physical function in community-dwelling people who fracture their hip. In situations where patients with a hip fracture are unable to provide this necessary information, KIs can provide reliable estimates of prefracture function to assist in setting appropriate rehabilitation goals.  相似文献

Aim: To compare clinical characteristics and outcome of nonagenarian hip fracture patients with younger patients aged 65–89 years. Methods: This was a cohort follow‐up study of admissions for a hip fracture between 2005–2010 (mean follow up of 3.5 years) in two teaching hospitals in the Netherlands; 230 nonagenarians and 1014 patients aged 65–89 years were included. Clinical characteristics, adverse events, mobility and mortality were compared. Results: Nonagenarians were more likely to be female and anemic (both P < 0.001), and had more trochanteric fractures (P = 0.005). The number of American Society of Anesthesiologists III/VI classified patients did not differ between the two groups. During the hospital stay, adverse events were more frequently observed in nonagenarians compared with younger patients (P < 0.001). The length of stay was significantly longer in nonagenarians (P < 0.001), and the 90‐day readmission rate was similar. Absolute mortality was higher in nonagenarians (P < 0.001), excess mortality, however, was comparable. Before admission, 40.0% of the nonagenarians lived in their own home, and 40.9% had returned 3 months postfracture. The rate of returning to their own home was lower compared with younger patients (P < 0.001). Prefracture mobility was worse in nonagenarians compared with the younger group, but 3 months after discharge, the number of patients that regained prefracture mobility was comparable in both age groups. Conclusions: Nonagenarian hip fracture patients differ significantly from younger patients aged 65–89 years with respect to clinical characteristics and long‐term outcome. However, almost half of the nonagenarians returned to their own home and more than half regained their prefracture level of mobility. Given these findings, prevention strategies for hip fracture and adverse events during hospital stay that focus particularly on frail nonagenarians are highly recommended.

The effects of persistent depressive symptoms on hip fracture recovery   总被引:4,自引:0,他引:4  
One hundred ninety-six older. White females were followed for 12 months after hip fracture. We examined the effects of persistently elevated depressive symptoms, measured by the Center for Epidemiological Studies Depression (CES-D) scale during a postsurgery interview and 2, 6, and 12 months later, on ambulation, overall physical function, and return to prefracture physical function 12 months after fracture. Age, prefracture physical function, and cognitive status were predictors of recovery. Controlling for these factors, persons consistently reporting few depressive symptoms were three times more likely than those with persistently elevated CES-D scores to achieve independence in walking, nine times more likely to return to prefracture levels in at least five of seven physical function measures, and nine times more likely to be in the highest quartile of overall physical function. These findings emphasize the importance of persistently elevated depressive symptoms for recovery. Routine screening, evaluation, and treatment of depression or depressed mood may be beneficial to the recovering hip fracture patient.  相似文献

Adjusted mortality after hip fracture: From the cardiovascular health study   总被引:1,自引:0,他引:1  
OBJECTIVES: To estimate the risk of death associated with hip fracture (HFx), stratifying by sex and time since fracture. DESIGN: Prospective cohort study compared participants with and without hip fracture, matched on sex, age, race, recruitment period, and time since enrollment. SETTING: The Cardiovascular Health Study, a more-than-15-year longitudinal study of 5,888 older individuals from four U.S. sites. PARTICIPANTS: Three hundred seventy-nine individuals with HFx were compared with 1,134 without HFx. MEASUREMENTS: Extended Cox models were used to estimate mortality hazard ratios (HRs) for different periods after fracture, adjusting for prefracture health. RESULTS: Age- and race-adjusted excess mortality was 9% in women and 24% in men 1 year after fracture, and 24% in women and 26% men 5 years postfracture. Multivariable-adjusted HRs of mortality associated with HFx in women were 7.1 (95% confidence interval (CI) = 2.3-21.5), 2.1 (95% CI = 1.0-4.1), 1.4 (95% CI = 1.1-2.0), and 1.0 (95% CI = 0.6-1.5) for 0 to 1 months, 2 to 6 months, 7 months to 4 years, and 5 to 8 years, respectively, after index date. In men, respective HRs for the same time periods were 39.9 (95% CI = 5.2-308.7), 3.8 (95% CI = 1.4-10.3), 1.1 (95% CI = 0.7-1.8), and 1.0 (95% CI = 0.3-2.7). HRs adjusted for age and race were 20% to 40% higher. CONCLUSION: The risk of mortality was highest in the first 6 months after HFx. In men, the risk of death approximated that of men without HFx after 6 months; in women, a moderately greater risk persisted through the fourth year. Although the mortality pattern was different in women and men, excess mortality 5 years postfracture was similar for both sexes.  相似文献

Aim: To measure functional recovery and determine risk factors for failure to return to the prefracture level of mobility of hip fracture patients 1 year postoperatively. Methods: A prospective cohort follow‐up study of 390 hip fracture patients aged 65 years and older was carried out. Patients were stratified in categories based on prefracture mobility: mobile without aid, with aid in‐ and outdoors, or only mobile indoors. Immobile patients were excluded. Risk factors for not regaining prefracture mobility were identified. Results: Nearly half of all patients regained their prefracture level of mobility after 1 year. Mobile patients without an aid were less likely to return to their prefracture mobility level compared with patients who were mobile with aid or mobile indoors. After 1 year, 18.7% of all patients had become immobile. Most important independent risk factors for failure to return to the prefracture level of mobility were a limited prefracture level of activities of daily living and a delirium during admission. Conclusions: The risk not to regain prefracture mobility is highest in mobile patients without an aid. The risk of becoming immobile is higher in those having a lower prefracture mobility. Activities of daily living dependence and delirium were the main risk factors for not regaining mobility. Geriatr Gerontol Int 2013; 13: 334–341 .  相似文献

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.  相似文献

OBJECTIVE: As part of a larger study to describe indices of recovery during the year after hip fracture, the current prospective study investigated longitudinal changes in serum and urine markers of bone metabolism for the year after hip fracture and related them to bone mineral density (BMD). DESIGN: A representative subset of participants provided serum and urine samples and had bone density measured at 3, 10, 60, 180, and 365 days postfracture. SETTING: Two Baltimore hospitals. PARTICIPANTS: The subjects were 205 community-dwelling, white women age 65 and older with fresh proximal femur fractures. MEASUREMENTS: Samples were assayed for specific bone-related proteins and bone turnover markers, including serum osteocalcin (OC), procollagen type 1 carboxy-terminal extension peptide (PICP), bone-specific alkaline phosphatase (BAP), and urinary deoxypyridinoline (DPD) cross-links. Selected hormonal regulators of bone metabolism, including parathyroid hormone (PTH), calcitonin (CT), 1,25-dihydroxy vitamin D(3) (1,25 (OH)(2)D), and estrone (E(1)) were measured from serum samples. Repeated measures analyses were used to evaluate postfracture changes in each of the markers. RESULTS: BAP, OC, and PICP were most active during the early postfracture period (3-60 days). BAP and OC remained elevated at 365 days compared with 3 days. DPD rose 48% from 3 days to 60 days, but this difference was not statistically significant. PTH and 1,25 (OH)(2)D increased steadily and significantly from 3 to 365 days. E(1) was highest at baseline and decreased at each time point, whereas CT showed no significant changes. When subjects were stratified into high-, medium-, and low-BMD groups based on their measurement at 3 days, both osteoclastic and osteoblastic markers in the low-BMD group displayed exaggerated and different patterns over time compared with the other groups. CONCLUSION: Currently, the standard treatment of care for hip fractures still results in high morbidity and mortality and failure to regain prefracture quality of life. Gaining an understanding of bone cell activity in these patients after hip fracture, derived by measuring markers longitudinally during recovery, provides a baseline by which to measure the effectiveness of new interventions to improve recovery from hip fracture.  相似文献

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.  相似文献
