The purpose of the present study was focused on the relationship between change in cognition and the functional outcome during rehabilitation in demented and non-demented adult hip fracture patients. We studied seventy consecutive adult patients with hip fracture admitted to our rehabilitation wards. Functional outcome was assessed by the Functional Independence Measure (FIM). The gain in cognition during the rehabilitation process was measured by the difference in Mini Mental State Examination scores at admission and discharge. Data was analyzed by t-test, chi square-test and linear regression. Patients without dementia presented and discharged from the rehabilitation ward with statistically significant higher total, motor, and gain functional independence measure scores compared to patients with dementia. In a multiple regression analyses, gain in Mini Mental State scores examination were not independently associated with higher total and motor functional independence measure scores at discharge (beta = 0.086, p = 0.194; beta = 0.077, p = 0.309, respectively). Our findings suggest that there is no association between functional outcome and cognitive gain at the end of the rehabilitation process among adult hip fracture patients with and without dementia. However hip fracture adult patients with dementia should not be deprived of a post-acute rehabilitation., (Copyright © 2018 Elsevier B.V. All rights reserved.)

The aim of the study was to evaluate whether rehabilitation of patients with recurrent ischemic strokes is associated with functional gain. We studied a total of 919 consecutive post-acute ischemic stroke elderly patients admitted for rehabilitation. 22% out of the patients had recurrent stroke on index day. Functional outcomes of first-ever stroke patients and recurrent ischemic stroke patients were assessed by the Functional Independence Measurement scale (FIM™) at admission and discharge. Data was analyzed by t-test, Chi-square test and by multiple linear regression analysis. There were 716 patients with first ever stroke and 203 patients with recurrent stroke. Total and motor FIM scores at admission and total, motor, gain and Montebello Rehabilitation Factor (RFG) FIM scores at discharge were similar in the two groups. A multiple linear regression analysis showed that age (beta=-0.13, p=0.001) length of stay (beta=0.21, p<0.001), Mini-Mental State Examination score (MMSE) (beta=0.1, p=0.01), and admission total FIM (beta=-0.12, p=0.01) emerged as the only independent predictors of higher gain FIM scores at discharge. The finding suggests that elderly patients with recurrent ischemic stroke admitted to rehabilitation ward, showed similar FIM gain scores at discharge, compared with first-ever stroke patients. It is concluded that recurrent stroke should not be considered as adversely affecting the short-term functional outcomes of patients in a post-acute rehabilitation setting., (Copyright © 2014 Elsevier Ireland Ltd.

The purpose of this study was to evaluate whether atrial fibrillation affects the short-term functional outcome of elderly patients with ischemic stroke, undergoing post-acute in-hospital rehabilitation. We studied 919 consecutive patients admitted for ischemic stroke rehabilitation, out of whom 19.6% were diagnosed with atrial fibrillation. The Functional outcome of atrial fibrillation (AF) and non-atrial fibrillation (Non-AF) patients were assessed by the Functional Independence Measurement scale (FIM) at admission and discharge. Data were analyzed by t-test, Chi-square test and by multiple linear regression analysis. Compared with Non-AF, patients with AF were slightly older (p<0.001), and had lower Mini-Mental State Examination (MMSE) scores (p=0.001). Discharge total FIM scores were significantly higher in Non-AF compared with AF patients (84.34 ± 29.44 vs. 79.02 ± 30.68, p=0.031). However, total and motor FIM gains at discharge were similar in the two groups. A multiple linear regression analysis showed that age (p<0.001), admission total and motor FIM (p<0.001) and MMSE score (p<0.001) emerged as the only independent predictors of total, motor and gain FIM scores at discharge. AF was not predictive, whatsoever, of adverse FIM scores (total, motor, gain) at discharge (β=-0.024, p=0.303; β=-0.019, p=-0.455 and β=-0.04, p=0.303, respectively). The finding suggests that Non-AF ischemic stroke elderly show higher total discharge FIM scores, compared with AF patients. However, both groups achieve similar FIM gains during rehabilitation period. AF should not be considered as adversely affecting the short-term rehabilitation process of such patients., (Copyright © 2013. Published by Elsevier Ireland Ltd.)

The purpose of this study was to investigate the effect of gender on the functional outcome after ischemic stroke. In a retrospective chart review we studied 919 survivors of ischemic stroke admitted for rehabilitation at a geriatric rehabilitation ward of a university affiliated hospital. Functional outcome of female and male patients was assessed by Functional Independence Measurement (FIM) at admission and discharge. Data were analyzed by t test, Chi-square test and Linear Regression. A total number of 919 patients were admitted of whom 56% were males. A higher proportion of male patients reported ischemic heart disease (p<0.001), hypercholesterolemia (p=0.035), Parkinson's disease (p=0.044), and previous stroke (p<0.001). Males had also higher Mini-Mental State Examination (MMSE) scores (p<0.001). Total FIM at admission (62.54 ± 25.98 and 66.00 ± 25.49; p=0.043), and total FIM at discharge (80.39 ± 30.35 and 85.59 ± 29.08; p=0.008), motor FIM at admission (40.04 ± 18.89 and 42.51 ± 18.47; p=0.047) and motor FIM at discharge (56.41 ± 23.04 and 60.44 ± 21.84; p=0.007) were higher among male patients. However, a trend for a borderline statistical difference was observed for FIM gains upon discharge between men and women. A multiple linear regression analysis showed that total FIM at discharge was neither associated with male nor female gender (β=-0.009; p=0.69). The findings suggest that the functional outcome of male survivors presenting for rehabilitation after acute ischemic stroke is slightly better. After adjusting for possible covariates, gender did not emerge as an independent predictor for higher FIM at discharge, suggesting that gender should not be held as adversely affecting rehabilitation of such patients., (Copyright © 2011 Elsevier Ireland Ltd.

The purpose of this study was to investigate how bladder management, rather than urinary incontinence, may affect the functional outcome of ischemic stroke patients. We studied 919 consecutive patients admitted for ischemic stroke rehabilitation. Level of bladder management was determined by Functional Independence Measurement (FIM TM) sub-scale scores relevant to bladder control. FIM scores less than 5 points was determined as low-bladder management score (Low-BMS) while FIM scores greater than 5 was determined as high-bladder management score (High-BMS). Data were analyzed by t-test, Pearson correlation, and chi-square test as well as by multiple linear regression analysis. There were 594 low-bladder score patients (Low-BMS) and 325 high-bladder score patients (High-BMS), at admission. Compared with High-BMS, Low-BMS patients were slightly older (p = 0.002), 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-BMS, yet their total FIM gain upon discharge was higher, compared with High-BMS (19.5 ± 16.46 vs. 17.59 ± 12.55, p = 0.07). Multiple linear regression analyses showed that total FIM at discharge was inversely associated with Low-BMS at admission (beta = -0.407; p<0.001) and age (beta = -0.127; p < 0.001). A high MMSE score (beta = 0.334; p < 0.001) emerged as predicting higher total FIM scores upon discharge. Low-BMS was independently predictive for total FIM gain at discharge (beta = 0.166; p < 0.001). The findings suggest that Low-BMS should be held as adversely affecting the rehabilitation outcomes of elderly stroke patients. However, Low-BMS patients do obtain significant gains and should not be deprived of rehabilitation., (Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.)

Low serum albumin level is associated with poor functional outcome and predicting a greater functional decline in the elderly. The aim of this study is to determine the interrelation between change of serum albumin level during rehabilitation period and functional outcome in hip fracture patients. We studied 433 consecutive elderly hip fracture patients admitted for rehabilitation. Functional outcome was assessed by the Functional Independence Measure (FIM) at admission and discharge of patients with no albumin gain (<0 g/dl) or with positive albumin gain (>or=0 g/dl). Data were analyzed by t-test, Pearson correlation, chi(2)-test and linear regression. Of patients 66.7% showed no albumin gain. These patients had a higher prevalence of previous stroke (p=0.04), lower Mini Mental State Examination (MMSE) scores (p=0.05) and were less likely to have hyperlipidemia (p=0.008) compared with patients with albumin gains. Admission and discharge FIM parameters and total and motor FIM gain/day were statistically significantly lower among patients with no albumin gain. In a linear regression analysis total FIM at discharge was inversely associated with pre-fracture function (beta=-0.148; p<0.001), Albumin gain (beta=0.047; p=0.005), high MMSE score (beta=0.143; p<0.001), and higher admission total FIM score (beta=0.69; p<0.001) emerged as significant predictors of higher total FIM scores upon discharge. The results suggest that patients with albumin gain have better admission and discharge FIM scores. Albumin gain emerged as a significant predictor for higher discharge FIM scores. We conclude that greater attention and efforts should be made regarding the dietary intervention and protein supplementation, in order to improve the rehabilitation outcome.

The purpose of this study was to investigate whether diabetes mellitus may affect the functional outcome of hip fractured patients. We studied 759 consecutive patients admitted for hip fracture rehabilitation, out of whom 18.2% were diabetics. The functional outcomes of diabetics and nondiabetics were assessed by the functional independence measurement scale (FIM) at admission and discharge. Data were analyzed by t-tests, Pearson correlation, and chi-square test as well as by multiple logistic regression analysis. Compared with nondiabetics, diabetic patients were slightly younger (p=0.003) and more hyperlipidemic (p=0.01), had a higher prevalence of previous stroke (p=0.03) and lower cognitive Mini-Mental State Examination (MMSE) scores (p=0.007). Absolute and relative FIM parameters, at admission and discharge, were similar in both groups. A multiple logistic regression analysis showed that diabetes was independently, and inversely, associated with male gender [odds ratio (OR), 2.11 (95% CI, 1.41-3.18)] and higher admission motor-FIM [OR, 1.05 (95% CI, 1.03-1.07)], whereas higher cognitive scores upon admission emerged as being "protective" for being in the motor-FIM gain <20 [OR, 0.94 (95% CI, 0.91-0.97)]. However, diabetes was not associated with any of the parameters indicating unsuccessful rehabilitation. The findings suggest that there is no difference in the functional outcome of diabetic and nondiabetic patients, presenting for rehabilitation after surgery of hip fractures. Diabetes should not be considered as adversely affecting rehabilitation of such patients.

The purpose of this study was to investigate blood transfusion patterns in elderly hip fractured patients and to determine the clinical predictive criteria for blood utilization. This retrospective study involved data analysis of 302 patients, undergoing surgical repair of pertrochanteric and subcapital fractures. Patients of the transfused group had significantly lower admission hemoglobin (P < 0.0001) and significantly more pertrochanteric fractures. About 80% of patients of the lowermost quartile of admission hemoglobin were transfused, compared with < 20% of the uppermost group (P < 0.0001). Admission hemoglobin levels < 12 g% and pertrochanteric fractures were independently associated with transfusions (odds ratio (O.R.) 0.475, C.I. 0.377-0.598, P < 0.0001 and O.R. 1.885, C.I. 1.05-3.215, P = 0.02, respectively). The results support the adoption of a policy considering primarily these two factors. Other factors we studied had no predictive power. Cross-matching may be reserved only for patients presenting with hemoglobin < 12 g% and pertrochanteric fractures. This practice seems safe and should help in reducing the extent of unnecessary blood ordering.

The onset of delirium is frequent in elderly patients who sustain hip fractures. The purpose of this study was to characterize different patterns of preoperative and postoperative delirium, to study factors associated with preoperative delirium and to evaluate the possible different outcome of these patients. This retrospective study comprised 281 elderly patients with hip fractures undergoing surgical fixation. Data collection included age, sex, length of stay, type of fracture, cognitive status by mini mental state examination (MMSE), assessment of possible delirium by the confusion assessment method (CAM) and functional outcome assessed by functional independence measure (FIM). A database search was conducted to identify whether delirium onset occurred prior to or following surgery. About 31% of the total sample developed delirium. Delirious patients tended to be more disabled (P = 0.03) and cognitively impaired (P = 0.018), compared with non-delirious patients. Most delirious cases (53%) had their onset in the preoperative period. Patients with preoperative delirium were older (P = 0.03), had a lower prefracture mobility (P < 0.01), impaired cognition (P = 0.04) and showed an adverse functional outcome in terms of FIM score. Regression analysis showed that prefracture dementia, prefracture mobility and low MMSE scores were strongly associated with higher probability of having preoperative delirium, with no additional effect of other variables. It is concluded that preoperative delirium should be viewed as a separate entity with unfavorable nature and adverse outcome. Careful preventive measures and better treating strategies should be employed to avoid this clinical condition.

Delirium is quite frequent in elderly patients who sustain hip fractures. The use of Meperidine by physicians, unaware of the possible emergence of delirium in elderly patients, is very popular. We have retrospectively examined the incidence of delirium in 181 consecutive patients admitted to the orthogeriatric ward with hip fractures. We used the confusion assessment method to establish the presence of delirium in all patients. A database search was conducted to identify which patients were treated by Meperidine, or Morphine, prior to delirium onset. We identified 92 cases, 44 of whom were treated by Meperidine alone, and the other 48 treated by Morphine alone. Delirium was diagnosed in 13 (27.1%) Morphine treated patients as compared with 19 (43.2%) treated by Meperidine (P<0.001). Age, cognitive status and opiate use were associated with perioperative delirium. A subset regression analysis showed that exposure to Meperidine was significantly associated with delirium (odds ratio 2.5, P<0.01), in contrast with Morphine. Our results confirm the association between exposure to Meperidine and delirium, suggesting that this drug should be withdrawn in elderly hip fractured patients undergoing surgery, and substituted by low dose Morphine analgesia. Reducing the incidence of delirium, by adopting such an approach, may result in a significant potential of savings in direct costs, related to treatment of delirium in this population.

The objectives of this study were to characterize patterns of opioid analgesia in elderly hip fracture patients, to investigate the possible differences in the treatment of cognitively impaired, delirious, or cognitively intact patients, and to study the factors that may affect the doses received by such patients. This retrospective study comprised 184 elderly patients with hip fractures undergoing surgical fixation. Data collection included age, sex, length of stay, type of fracture, cognitive status by mini-mental state examination, assessment of possible delirium by the confusion assessment method, type and doses of opioid received by these patients. We found that the amount of morphine equianalgesic dose differed significantly between demented and non-demented patients (7.5 +/- 1.8 vs. 14.1 +/- 4.9, P<0.001). Patients with cognitive decline or with delirium received only 53 and 34%, respectively, of the amount of opioid that was administered to cognitively intact patients. A significant association was observed between cognitive status, or delirium, and amount of opioid analgesia (P<0.001 and P=0.003, respectively). Other parameters such as age, length of stay and type of fracture, had no effect on the use of opioid analgesia. It is concluded that the management of pain in older persons with hip fracture surgery is suboptimal with regards to insufficient administration of opioid analgesia in demented and delirious patients. The adoption of a standardized protocol for pain control may help in reducing the extent of this problem.
