The association between Norton scale gain and functional outcome among older hip fracture patients.

AIM: This study examines interrelations between gains of Norton Scale Score (NSS) and functional outcome measured by Functional Independence Measurement (FIM) among older hip fracture patients. DESIGN: Retrospective study. METHODS: We examined 227 patients consecutively hospitalized in a geriatric postacute rehabilitation ward. The data were collected during 2012-2017. Data were analysed using Student's t test, chi-square test, Pearson's correlation coefficient and linear regression. RESULTS: Patients with positive NSS gains demonstrated statistically significant higher total FIM, motor FIM and total FIM gain scores at hospital discharge, compared with patients showing no NSS gains or negative NSS. Multiple regression analysis indicated that positive NSS gains were independently predictive for higher total FIM and motor FIM scores at hospital discharge and higher motor FIM gains at discharge. CONCLUSION: Our results suggest that positive NSS gains are associated with higher FIM scores at hospital discharge and may assist in predicting the functional outcome of hospitalized older hip fracture patients.

Prerehabilitation alanine aminotransferase blood levels and one-year mortality rates in older adults following hip fracture.

Low alanine aminotransferase (ALT) blood levels prior to rehabilitation are associated with poor function in older adults following hip fracture. We hypothesized that low ALT blood levels prior to rehabilitation were also associated with one-year mortality in this population. Included were 456 older adults (age ≥ 60 years, 82.5% women) admitted for rehabilitation following hip fracture. ALT blood levels were documented between one and six months prior to rehabilitation. Excluded were patients with ALT blood levels over 40 IU/L possibly consistent with liver injury. The main outcome was all-cause mortality one year following rehabilitation admission. The study group included 142 (31.1%) patients with low (≤10 IU/L) ALT blood levels and the control group included 314 (68.9%) patients with high-normal (11-40 IU/L) ALT blood levels. Overall, 52 (11.4%) patients died within one year following rehabilitation admission. Compared with the control group, patients with low ALT blood levels had significantly higher 1-year mortality rates [17.6 vs. 8.6%, odds ratio 2.27, 95% confidence interval (CI) 1.27-4.08]. Cox regression analysis showed that low ALT blood levels prior to rehabilitation were associated with one-year mortality (hazard ratio 1.88, 95% CI 1.08-3.28) together with age (hazard ratio 1.06, 95% CI 1.02-1.11), independent of gender. However, this association was no longer significant following adjustment also for peripheral vascular disease, admission and discharge functional independence measure scores, albumin serum levels, and length of rehabilitation. In conclusion, low ALT blood levels prior to rehabilitation are associated with one-year mortality in older adults following hip fracture. They may be used when only age and gender are known.

Statins and Selective Serotonin Reuptake Inhibitors are Associated with Longer Survival in Nursing Home Residents.

BACKGROUND: Statins and selective serotonin reuptake inhibitors (SSRIs) have beneficial effects on health outcomes in the general population. Their effect on survival in debilitated nursing home residents is unknown. OBJECTIVES: To assess the relationships between statins, SSRIs, and survival of nursing home residents. METHODS: Baseline patient characteristics, including chronic medications, were recorded. The association of 5-year survival with different variables was analyzed. A sub-group analysis of survival was performed according to baseline treatment with statins and/or SSRIs. RESULTS: The study comprised 993 residents from 6 nursing homes. Of them, 285 were males (29%), 750 (75%) were fully dependent, and 243 (25%) were mobile demented. Mean age was 85 ± 7.6 years (range 65-108). After 5 years follow-up, the mortality rate was 81%. Analysis by sub-groups showed longer survival among older adults treated with only statins (hazard ratio [HR] for death 0.68, 95% confidence intervals [95%CI] 0.49-0.94) or only SSRIs (HR 0.6, 95%CI 0.45-0.81), with the longest survival among those taking both statins and SSRIs (HR 0.41, 95%CI 0.25-0.67) and shortest among residents not taking statins or SSRIs (P < 0.001). The survival benefit remained significant after adjusting for age and after conducting a multivariate analysis adjusted for sex, functional status, body mass index, mini-mental state examination, feeding status, arrhythmia, diabetes mellitus, chronic kidney disease, and hemato-oncological diagnosis. CONCLUSIONS: Treatment with statins and/or SSRIs at baseline was associated with longer survival in debilitated nursing home residents and should not be deprived from these patients, if medically indicated.

Functional Outcome of Elderly Hip Fracture Patients Is Not Affected By Prefracture Dementia.

OBJECTIVE: The aim of the study was to examine whether a diagnosis of prefracture dementia (PFD) affects functional outcome at discharge from a geriatric rehabilitation setting. DESIGN: A total of 211 consecutive elderly hip fracture patients were evaluated retrospectively. We used the Functional Independence Measure (FIM) and analyzed data by t test, χ(2) test, and multiple linear regression analysis. RESULTS: Patients with PFD were older (P = 0.001), presented with lower Mini-Mental State Examination scores (P < 0.001) and lower prefracture function (P < 0.001). Total-FIM and motor-FIM scores at admission and discharge, as well as FIM gain scores at discharge, were lower among patients with PFD, compared with nonprefracture dementia (NPFD) patients (P < 0.001). The FIM daily gains (efficiency) (P < 0.001) and Montebello relative functional scores (P < 0.001) were also lower in PFD, compared with patients with NPFD. However, linear regression analysis showed that PFD did not predict total, motor, or FIM gain at discharge (ß = -0.11, P = 0.115; ß = -0.06, P = 0.412; ß = -0.099, P = 0.329, respectively). Upon discharge, patients with PFD achieved lower FIM scores yet maintained similar motor-FIM gains compared with patients with NPFD. CONCLUSIONS: Our study results supports the inclusion of patients with PFD in postfracture rehabilitation programs.

Alanine aminotransferase blood levels and rehabilitation outcome in older adults following hip fracture surgery.

Low alanine aminotransferase (ALT) blood levels are associated with frailty and poor outcome in older adults. Therefore, we studied the association between ALT blood levels before rehabilitation and rehabilitation outcome in older adults following hip fracture surgery. A total of 490 older adults (age>60 years, mean age: 82.9±6.7 years, 82.0% women) admitted to rehabilitation following hip fracture surgery were included. The rehabilitation outcome was assessed by Functional Independence Measure (FIM) scores. ALT blood levels were documented between 1 and 6 months before rehabilitation. Patients with ALT blood levels over 40 IU/l possibly consistent with liver injury were excluded. The cohort was divided into two groups: patients with ALT more than 10 IU/l and patients with ALT less than or equal to 10 IU/l. Upon rehabilitation discharge, the FIM outcome measures (motor, cognitive, gain, efficiency) were significantly higher in patients with ALT more than 10 IU/l relative to patients with ALT less than or equal to 10 IU/l (P<0.05). A logistic regression analysis adjusted for age and sex showed that patients with ALT more than 10 IU/l were more likely to have higher (second to fourth upper quartiles) total FIM scores (>50), cognitive FIM scores (>16), and FIM efficiency (>0.228) upon rehabilitation discharge (odds ratio=1.56-1.78). However, this association was no longer significant following adjustment also for admission total FIM score, cognitive impairment, cancer, and albumin serum levels. High-normal ALT blood levels before rehabilitation are associated with a better rehabilitation outcome in older adults following hip fracture surgery. It may be used when data on admission FIM score, cognitive impairment, cancer, and albumin serum levels are not available.

Does Polypharmacy in Nursing Homes Affect Long-Term Mortality?

OBJECTIVES: To investigate the association between polypharmacy and mortality in nursing home (NH) residents. DESIGN: Prospective observational cohort study. SETTINGS: Six NHs in central Israel. PARTICIPANTS: Mobile with dementia and fully dependent residents (N = 764; n = 558 (73%) fully dependent, n = 206 (27%) mobile residents with dementia requiring institutional care; mean age 82.2 ± 5.9). MEASUREMENTS: Two-year mortality and its association with number of drugs that individual residents were taking at baseline, controlled for multiple confounders. RESULTS: At baseline, 268 residents were taking five or fewer drugs per day, 202 were taking six or seven, and 294 were taking eight or more. In the multivariate analysis, the likelihood of dying within 2 years in the group taking six or seven drugs per day (odds ratio (OR = 0.95, 95% CI = 0.63-1.43) and in those taking eight or more (OR = 1.20, 95% CI = 0.78-1.84) was similar to that of those taking five or fewer. Variables at baseline independently associated with greater mortality were male sex (OR = 1.75, 95% CI = 1.24-2.46), older age (OR = 1.07, 95% CI = 1.04-1.10), higher Charlson Comorbidity Index (OR = 1.17, 95% CI = 1.04-1.30), and taking anticoagulant (OR = 1.78, 95% CI = 1.01-3.13) or antihyperglycemic medication (OR = 1.69, 95% CI = 1.12-2.53). Variables at baseline independently associated with lower mortality were higher body mass index (OR = 0.99, 95% CI = 0.93-0.99) and taking lipid-lowering medication (OR = 0.54, 95% CI = 0.36-0.80) and selective serotonin reuptake inhibitors or serotonin-norepinephrine reuptake inhibitors (OR = 0.52, 95% CI = 0.37-0.75). CONCLUSION: Polypharmacy, defined quantitatively according to number of drugs, was not associated with mortality in these NH residents.

Pre-stroke dementia does not affect the post-acute care functional outcome of old patients with ischemic stroke.

AIM: The purpose of the present study was to evaluate whether a diagnosis of dementia before stroke onset (pre-stroke dementia [PSD]) affects the short-term functional outcome of elderly ischemic stroke patients. METHODS: This was a retrospective case-control study comprising of consecutive elderly ischemic stroke patients. Functional outcome was assessed by the Functional Independence Measure scale (FIM) at admission and discharge. Data was analyzed by t-test, χ(2) -test, multiple linear regression analysis and logistic regression. RESULTS: There were 919 patients with acute ischemic stroke, out of whom 11.5% were diagnosed with PSD on index day. Compared with non-PSD patients, those with pre-stroke dementia had a shorter length of stay (P < 0.001), higher rate of female patients (P < 0.001) and lower Mini-Mental State Examination scores (P < 0.001). Both total and motor FIM scores at admission and discharge, and their respective FIM gain scores at discharge were higher in non-PSD compared with PSD patients (P < 0.001). In logistic regression analysis to identify factors predicting successful outcome (defined as total FIM at discharge ≥80), PSD remained as significantly associated with increased risk for adverse outcome on discharge (OR 2.449, CI 1.207-4.970, P = 0.013). CONCLUSIONS: The present findings suggest that a diagnosis of pre-stroke dementia is associated with lower FIM scores at admission and discharge in patients with ischemic stroke. Yet, daily motor FIM gains were similar in PSD and non-PSD patients, suggesting that these patients should not be deprived of a post-acute rehabilitation, based on a diagnosis of dementia before stroke onset.

Perioperative urinary retention, short-term functional outcome and mortality rates of elderly hip fracture patients.

AIM: Perioperative urinary retention (POUR) is common among hip fracture patients. The aim of the present study was to compare the prevalence, risk factors, functional outcomes and survival rates of patients with and without POUR. METHODS: This was a retrospective chart review study that was carried out in an orthogeriatric hip fracture unit. A total of 639 consecutive hip fracture patients who had hip surgery followed by a standard rehabilitation course participated in the study. Post-void residual volume (PVRV), Functional Independence Measure (FIM) scores (total and motor FIM, FIM gain) and mortality rates (90 and 365 days, end of follow up) were measured. RESULTS: A total of 328 patients (51.3%) suffered from POUR. Diabetes (OR 1.55, 95% CI 1.04-2.31), urinary infection (OR 3.25, 95% CI 2.16-4.90) and delirium (OR 1.66. 95% CI 1.09-2.52) emerged as the best predictors for POUR. Functional gains were slightly better in patients without POUR (P = 0.037 and P = 0.023, for discharge motor and total FIM gain, respectively). There were no differences in FIM gains at discharge in male patients, whether with or without POUR. However, female patients without POUR showed significantly better motor and total FIM gains on discharge (P = 0.003 and P = 0.003, respectively), compared with females with POUR. In multiple linear regression analyses, POUR in female (but not male) patients was predictive for adverse motor FIM gain (beta = -0.089, P = 0.046). In Cox regression analysis, urinary retention was not associated with mortality rates. CONCLUSIONS: POUR is highly prevalent in elderly hip fracture patients. It adversely affects the functional outcome of female patients, but is not associated with increased mortality rates.

Gender differences in functional outcome of elderly hip fracture patients.

AIM: The purpose of the present study was to investigate whether gender might affect functional outcome of hip fractured patients undergoing in-hospital rehabilitation. METHODS: This was a retrospective chart review study comprising of 759 consecutive elderly patients suffering traumatic hip fracture. All patients underwent a standard orthogeriatric care of surgical hip repair and post-acute rehabilitation care. Functional outcome (female vs male gender) was assessed by motor and total Functional Independence Measurement (FIM) scores on discharge. Data was analyzed by t-tests χ(2) -test and multiple linear regression analyses. RESULTS: A total of 574 (75.6%) out of all patients were females. There were no differences in admission FIM scores; however, male patients had a higher prevalence of comorbidities. FIM scores on discharge were higher in female patients (motor FIM, P=0.007; motor FIM gain, P=0.001; compared with males). A multiple linear regression analysis showed that female gender was independently associated with higher total FIM at discharge (ß coefficient=0.056, P=0.008), higher motor FIM at discharge (ß coefficient=0.071, P=0.007) and higher total FIM gain at discharge (ß coefficient=0.11, P=0.008). CONCLUSION: The findings suggest that absolute discharge FIM scores of females are higher, compared with male patients. After adjusting for possible covariates, female gender still emerged as an independent predictor for higher FIM at discharge, suggesting that male gender should be considered as adversely affecting rehabilitation outcome of hip fracture male patients.

Rates, variability, and associated factors of polypharmacy in nursing home patients.

OBJECTIVES: To determine the rate and variability of polypharmacy in nursing home (NH) residents and investigate its relationship to age, sex, functional status, length of stay, and comorbidities. METHODS: We conducted a cross sectional, multicenter study that included six nursing homes. Demographic, clinical characteristics, Charlson comorbidity index (CCI), the number and classes of chronic medications, rate of polypharmacy >5 drugs (per day) and polypharmacy >7 drugs (per day) were recorded. RESULTS: Nine hundred and ninety-three residents were included; 750 (75.5%) fully dependent residents and 243 (24.5%) mobile demented residents requiring institutional care. The mean age was 85.04±7.55 (65-108) years. The mean rates of polypharmacy >5 drugs and polypharmacy >7 drugs were 42.6% and 18.6%, respectively. Differences in polypharmacy >5 drugs and polypharmacy >7 drugs were observed in NHs 24.7%-56% and 4.9%-30.4%, respectively (P<0.001). Mean number of chronic drugs per resident was 5.14±2.60 from 3.81±2.24 to 5.95±2.73 (P<0.001). No differences in polypharmacy were found between sex and fully dependent versus mobile demented residents. The most common medications taken were for gastrointestinal, neurological, and cardiovascular disorders. Regression analysis revealed four independent variables for polypharmacy >5 drugs: groups aged 75-84 and >85 relative to 65-74, odds ratio (OR) 0.46 (95% confidence interval [CI] 0.27-0.78) P=0.004, OR 0.35 (95% confidence interval 0.19-0.53), respectively, P<0.001; length of stay >2 years, OR 0.51 (95% CI 0.36-0.73) P<0.001; CCI, OR 1.58 (95% CI 1.42-1.75) P<0.001; and feeding tube versus normal feeding, OR 0.27 (95% CI 0.12-0.60) P=0.001. CONCLUSION: Rates of polypharmacy in NHs are high with significant variability. Variability rates of polypharmacy, distinct residents' characteristics, and excessive use of certain drug groups may indicate that a decrease in medication is potentially feasible.

A cost-utility analysis of a comprehensive orthogeriatric care for hip fracture patients, compared with standard of care treatment.

BACKGROUND: The economic burden associated with hip fractures calls for the investigation of innovative new cost-utility forms of organisation and integration of services for these patients. OBJECTIVE: To carry out a cost-utility analysis integrating epidemiological and economic aspects for hip fracture patients treated within a comprehensive orthogeriatric model (COGM) of care, as compared with standard of care model (SOCM). DESIGN: A demonstration study conducted in a major tertiary medical centre, operating both a COGM ward and standard orthopaedic and rehabilitation wards. METHODS: Data was collected on the clinical outcomes and health care costs of the two different treatment modalities, in order to calculate the absolute cost and disability-adjusted life years (DALY) ratio. RESULTS: The COGM model used 23% fewer resources per patient ($14,919 vs. $19,363) than the SOCM model and to avert 0.226 additional DALY per patient, mainly as a result of lower 1-year mortality rates among COGM patients (14.8% vs. 17.3%). CONCLUSION: A comprehensive ortho-geriatric care modality is more cost-effective, providing additional quality-adjusted life years (QALY) while using fewer resources compared with standard of care approach. The results should assist health policy-makers in optimising healthcare use and healthcare planning.

Eating management and functional outcome of elderly patients with symptomatic ischemic stroke undergoing inpatient rehabilitation.

AIM: The purpose of this study was to investigate whether, and to what extent, post-stroke eating management (EM) at admission to a rehabilitation ward is associated with functional outcome. METHODS: This was a retrospective study comprising 716 consecutive elderly patients with first ever symptomatic ischemic stroke. Level of eating management was determined by Functional Independence Measurement (FIM) subscale scores relevant to eating management, where scores ≤ 5 points define low-eating management (Low-EM) ability and scores >5 indicate independent eating management. Data was analyzed by t-test, χ(2) -test, Pearson's correlation and by multiple linear regression analysis. RESULTS: A total of 418 and 298 Low-EM and High-EM patients, respectively, were eligible for final analysis. Compared with High-EM, Low-EM patients were slightly older (P=0.04), had longer rehabilitation stays (P<0.001) and lower Mini-Mental State Examination (MMSE) scores (P<0.001). Total FIM at admission and discharge were lower in Low-EMS, yet there was no statistically significant difference in total FIM gain on discharge between the two groups. Multiple linear regression analyses showed that total FIM at discharge was inversely associated with Low-EM at admission (ß-coefficient= -0.389, P<0.001). Low-EM scores were independently predictive for higher total FIM gain at discharge (ß-coefficient=0.125, P=0.005). CONCLUSION: The findings suggest that impaired eating management on admission is associated with adverse functional outcome. However, patients presenting to rehabilitation with impaired eating management do obtain significant functional gains and should not be deprived of rehabilitation.

Increased 1-year mortality rates among elderly hip fracture patients with atrial fibrillation.

BACKGROUND AND AIMS: Prediction of factors associated with survival following hip fracture is important. We studied crude and adjusted survival rates in elderly hip fracture patients with and without atrial fibrillation (AF) to assess possible risk of death associated with AF. METHODS: A historical prospective cohort study, comprising 1114 consecutive patients with hip fractures. Subjects were divided into three groups: patients with sinus rhythm (SR), paroxysmal atrial fibrillation (PAF) or chronic atrial fibrillation (CAF). The main outcome measures were crude and adjusted survival rates at 30, 90 and 365 days, and end of follow-up. RESULTS: AF patients differed from SR patients by gender (p=0.0018), age (p=0.008), heart failure (p<0.001), ischemic heart disease (p<0.001) and history of a stroke (p<0.001). The lowest death rates were observed among SR and PAF patients, whereas CAF patients had the highest rates at each follow-up time point. CAF (but not PAF or SR) patients were at a significantly higher risk of death at both 365 days and at the end of the study (HR 1.786, CI 1.011- 3.155 and HR 1.835, CI 1.302-2.585, respectively). Older age (HR 1.301, CI 1.135-1.491 and HR 1.321, CI 1.321-1.415) and male gender (HR 1.879, CI 1.271- 2.779 and HR 1.545, CI 1.251-1.909) also predicted higher risk of death at both 365 days and at the end of the study. CONCLUSIONS: Atrial fibrillation cannot be considered to adversely affect short-term survival of hip fracture patients. After 365 day, CAF was associated with a significantly higher risk of death.

Atrial fibrillation is not associated with rehabilitation outcomes of elderly hip fracture patients.

AIM: To study possible differences in rehabilitation outcomes of patients with hip fracture, with and without atrial fibrillation. METHODS: A retrospective cohort study comprising 1114 patients, divided into three groups: patients with sinus rhythm, paroxysmal atrial fibrillation or chronic atrial fibrillation. All patients underwent a standard orthogeriatric care comprising surgical hip repair and a rehabilitation course. Main outcome measures included functional status at discharge by the Functional Independence Measure, post-fracture functional status category and type of postdischarge living arrangement. RESULTS: Patients with atrial fibrillation differed from patients in sinus rhythm by female sex (P = 0.018), older age (P = 0.008) and higher rates of heart failure (P < 0.001), ischemic heart disease (P < 0.001), previous stroke (P < 0.001), and American Society of Anesthesiologists score (P < 0.001). No differences were observed among the three groups regarding Functional Independence Measure motor and total scores. In regression analysis, Mini-Mental State Examination (P < 0.001), prefracture status (P < 0.001), postsurgery motor Functional Independence Measure (P < 0.0001) and Parkinson's disease (P = 0.009) were predictive of higher motor Functional Independence Measure at discharge, whereas atrial fibrillation had no predictive value whatsoever. There were no differences among groups in magnitude of postfracture change of functional status category or type of postdischarge living arrangement. CONCLUSIONS: Discharge motor Functional Independence Measure scores, postfracture changes in functional status and in discharge placement are similar in hip fracture patients with sinus rhythm, compared with those with atrial fibrillation. Atrial fibrillation should not be considered to adversely affect the rehabilitation outcome of these patients.

Functional outcome of elderly survivors of ischemic stroke: a retrospective study comparing nonhypercholesterolemic and hypercholesterolemic patients.

BACKGROUND: Total cholesterol is significantly associated with increased risk of ischemic stroke. Patients with ischemic stroke and high cholesterol levels may show better functional outcome after rehabilitation. OBJECTIVES: To study the possible interrelations between hypercholesterolemia and functional outcome in elderly survivors of ischemic stroke. METHODS: We conducted a retrospective chart review study of consecutive patients (age > or = 60 years) with acute stroke admitted to a geriatric rehabilitation ward in a university-affiliated hospital. The presence or absence of hypercholesterolemia was based on registry data positive for hypercholesterolemia, defined as total cholesterol > or = 200 mg/dl (5.17 mmol/L). Functional outcome of patients with hypercholesterolemia (Hchol) and without (NHchol) was assessed by the Functional Independence Measurement scale (FIM) at admission and discharge. Data were analyzed by t-test and chi-square test, as well as linear regression analysis. RESULTS: The complete data for 551 patients (age range 60-96 years) were available for final analysis; 26.7% were diagnosed as having hypercholesterolemia. Admission total FIM scores were significantly higher in patients with Hchol (72.1 +/- 24.8) compared with NHchol patients (62.2 +/- 24.7) (P < 0.001). A similar difference was found at discharge (Hchol 90.8 +/- 27.9 vs. NHchol 79.7 +/- 29.2, P < 0.001). However, total FIM change upon discharge was similar in both groups (18.7 +/- 13.7 vs. 17.6 +/- 13.7, P = 0.4). Regression analyses showed that high Mini Mental State Examination scores (beta = 0.13, P = 0.01) and younger age (beta = -0.12, P = 0.02) were associated with higher total FIM change scores upon discharge. Total cholesterol was not associated with better total FIM change on discharge (beta = -0.012, P = 0.82). CONCLUSIONS: Elderly survivors of stroke with Hchol who were admitted for rehabilitation showed higher admission and discharge FIM scores but similar functional FIM gains as compared to NHchol patients. High cholesterol levels may be useful in identifying older individuals with a better rehabilitation potential.

Improved survival of hip fracture patients treated within a comprehensive geriatric hip fracture unit, compared with standard of care treatment.

OBJECTIVES: To compare survival rates of hip fracture patients treated within a comprehensive geriatric hip fracture unit (CGHFU) with those undergoing a standard of care treatment (SOCT) in general orthopedic wards. DESIGN: Retrospective chart review. SETTING: A geriatric hip fracture unit of a division of geriatric medicine and rehabilitation and departments of general orthopedic surgery of a tertiary hospital. PARTICIPANTS: Participants were 3114 consecutive hip fracture patients: 847 were admitted to CGHFU and 2267 to wards of general orthopedics. INTERVENTION: Surgical repair followed by standard rehabilitation course MEASUREMENT: Mortality rates at 30 days, 90 days, and 1 year. RESULTS: CGHFU population was older (P < .0001), comprised more women (P < .0001), and suffered a greater number of comorbidities (P < .0001). Crude 30-day mortality rates were 1.9% and 3.0% for CGHFU and SOCT, respectively. At 90 days, crude rates were 6.5% and 8.1%, respectively, and 14.8% and 17.3%, at 1 year, respectively. Cox proportional hazard models adjusted for sociodemographics, Comorbidity, and surgery characteristics showed borderline significant lower mortality hazard ratios for CGHFU in comparison with SOCT, for 1-month and 3-month intervals. The adjusted Cox model favored the CGHFU modality of care with regard to 1-year cumulative mortality (hazard ratios 0.78, 95% confidence interval 0.63-0.96, P = .016). Male gender, age, diabetes, and number of operations were predictive of increased 1-year mortality risk in the separate regression models by gender and age group (<85, 85+). CONCLUSION: Crude and adjusted mortality rates are lower in a geriatric hip fracture unit, as compared with the common standard of care model of general orthopedic wards. Combined with earlier data on improved functional outcomes of CGHFU, these findings further support the implementation of similar comprehensive orthogeriatric models of care.

Elevated blood urea, independent of glomerular filtration rate (GFR), confers increased risk of adverse functional outcome in elderly hip fracture patients.

This retrospective cohort study investigated the possible interrelations of GFR and functional outcome in elderly hip fracture patients. The final analyses comprised 499 consecutive patients undergoing standard medical, surgical and rehabilitation treatment in an orthogeriatric unit of a tertiary care hospital. Functional outcomes were assessed by Functional Independence Measurement (FIM™) scores. Kidney function was assessed by blood urea and creatinine, as well as by GFR according to the modification diet of renal disease study (MDRDS) formula. Mean age was 83.60 ± 5.14 and mean GFR 61.07 ± 17.22 ml/min. GFR was <60 ml/min in 91.8% out of all patients. FIM admission and discharge scores, and gains, were not associated with GFR values, except for discharge motor FIM which was significantly higher in patients with GFR greater than 30 ml/min (p = 0.043). In regression analysis, GFR was associated with motor FIM at discharge (ß = 0.028, p = 0.022). Neither GFR nor creatinine was associated with discharge total FIM. In contrast, lower admission urea levels were predictive of higher motor (correlation coefficient (CC) = 0.151, odds ratio (OR) 0.132, 95% confidence interval (CI) = 0.027-0.237, p = 0.013) and total FIM scores (CC = -0.022, OR = 0.978, 95%CI = 0.960-0.997, p = 0.022) at discharge. We suggest that GFR and creatinine are poorly associated with functional outcome. Instead, urea is more likely to predict functional outcome, and may serve as more reliable biomarker for the prognostication of functional outcome.

Atrial fibrillation predicts cognitive impairment in patients with ischemic stroke.

BACKGROUND: Atrial fibrillation (AF) is considered as a risk factor for cognitive impairment. METHODS: This retrospective chart review study was conducted in a patient stroke rehabilitation ward of a university-affiliated referral hospital. The participants were 707 patients admitted for a standard rehabilitation course after an ischemic stroke. Cognitive status was assessed by the Mini-Mental State Examination (MMSE), and scores lower than 24 points were considered as suggestive of cognitive impairment. RESULTS: Atrial fibrillation, age, gender, diabetes, and dementia emerged as the only statistically significant parameters differing between those with MMSE score lower than 24 or higher. In a multiple logistic regression analysis, AF (odds ratio 1.6, 95% confidence interval 1.03-2.47, P = .03) was associated with an increased risk of cognitive impairment. CONCLUSIONS: Our findings suggest that atrial fibrillation upon admission is independently associated with lower MMSE scores in patients with ischemic stroke.

MK-0677 (ibutamoren mesylate) for the treatment of patients recovering from hip fracture: a multicenter, randomized, placebo-controlled phase IIb study.

Most elderly patients admitted for hip fracture suffer functional decline. Previous studies with MK-0677 in hip fracture patients suggested possible benefits to functional recovery. This is a randomized, double-blind study of 123 elderly hip fracture patients assigned to receive 25mg/day of MK-0677 (n = 62) or placebo (n = 61). Primary outcomes were a rank analysis of change during the study in objective functional performance measurements and insulin-like growth factor-1 (IGF-1) levels in blood. At 24-weeks, the mean stair climbing power increased by 12.5 W in the MK-0677 group (95% confidence interval (CI) = -10.95-35.88; p = 0.292) compared with placebo. Gait speed increased by a 0.7-score difference in the means (95% CI = 0.17-1.28; p = 0.011). There was no improvement in MK-0677 treated patients in several other functional performance measures. The MK-0677 group experienced fewer falls during the study compared to placebo and smaller number of patients who had any falls (p = 0.096). Levels of IGF-1 in treated patients increased by 51.4 ng/ml (95% CI = 34.42-68.44; p < 0.001) compared to placebo. Trial was terminated early due to a safety signal of congestive heart failure in a limited number of patients. In hip fracture patients treated with 25mg/day MK-0677, the increase in plasma IGF-1 levels was not paralleled by improvement in most functional performance measures. MK-0677 has an unfavorable safety profile in this patient population.

[The bacteriological profile of bacteriuria in residents of a long-term geriatric facility].

BACKGROUND: Little is known on the bacteriological profile of consecutive urine samples in elderly patients institutionalized in nursing homes. AIM: This retrospective study aims to characterize urinary pathogens, rates of isolation of the same pathogen in subsequent urine samples and predicting factors associated with such repeated isolations. Data were retrospectively retrieved from medical charts of nursing home patients during a four-year period. The authors looked for changes in rates of positive cultures, changes in urine flora, in rates of repeated isolation of the same pathogens and the possible interrelations with the use of antibiotics. METHODS: A total number of 3229 urine cultures were studied, 1311 of which (43%) were positive and 493 out of these positive cultures (37.6%) were treated with antibiotics. The rates of positive cultures increased consistently during the study period (p=0.003). E. coli (68.1%), Klebsiella pneumoniae and Proteus mirabilis accounted for more than 90% of positive cultures. RESULTS: There was no difference with regard to pathogen types isolated from symptomatic or asymptomatic cases. The rates of recurrent bacteriuria, by the same pathogen isolated at baseline urine culture, were similar in treated and untreated cases. A regression analysis aiming to predict factors associated with subsequent positive cultures had negative results, except for cases of untreated bacteriuria with pseudomonas (CI 1.36-7.09, O.R. 3.11, p=0.006). CONCLUSION: Our data support earlier studies underscoring the need to carefully consider the role of antibiotics and for better clinical guidelines for the treatment of bacteriuria in this population.
