Absence of combined effects of anemia and bilateral surgical status on inpatient rehabilitation outcomes following total knee arthroplasty

Purpose.?To examine the effects of anemia on inpatient rehabilitation outcomes following unilateral and bilateral total knee arthroplasty (TKA).

Method.?This was a multicenter, retrospective study from 15 inpatient rehabilitation facilities. Patients (N?=?5421) with very low hematocrit (Hct?<30%), low Hct (30–36% women, 30–41% men), or normal Hct (>36% women, 41% men) were included. Inpatient rehabilitation occurred following TKA. Functional independence measure (FIM) scores, length of stay (LOS), itemized hospital charges, discharge destination were main outcomes.

Results.?LOS was 13% longer and hospital charges were 12.5–18.0% higher in the very low Hct than remaining groups (p?=?0.0001). The FIM score and subscores for walking, stair climbing, bathing, transfers, and dressing changes were comparable for all Hct groups for the overall score. Hct?<30% did not correspond to worse outcomes in patients with bilateral surgeries compared with unilateral surgeries; total FIM scores improved 47–53% across all Hct groups, regardless of bilateral surgical status. Discharge to home ranged 92.6–94.7% across all Hct groups (p?>?0.05).

Conclusions.?Rehabilitation teams can expect comparable functional improvements and discharge to home in anemic and non-anemic patients with either unilateral or bilateral surgeries without hematologic correction in the rehabilitation setting, but might need an additional day to accomplish these outcomes.     

A preliminary examination of the CMS eligibility criteria in total-joint arthroplasty

OBJECTIVE: To analyze inpatient rehabilitation outcomes in total-knee arthroplasty (TKA) and total-hip arthroplasty (THA) patients using the 2004 Medicare 75% rule criteria. DESIGN: This retrospective study compared outcomes in unilateral TKA (UTKA), bilateral TKA (BTKA), and THA after interdisciplinary inpatient rehabilitation (n = 867). Patients were separated into three comparison pairs: 1) UTKA or BTKA, 2) age <85 yrs or > or =85 yrs, and 3) body mass index (BMI) <50 or > or =50 kg/m. Length of stay (LOS), functional independence measure (FIM) scores (total, motor, and cognitive), hospital charges, FIM efficiency, and discharge disposition were analyzed. RESULTS: BTKA improved total FIM score more than UTKA (43 vs. 38%; P = 0.039). TKA with BMI > or =50 kg/m had similar admission and discharge FIM motor scores compared with BMI <50 kg/m (P > 0.05). TKA patients > or =85 yrs had lower admission FIM scores, longer LOS (11.3 vs. 9.4 days), and 22% higher total charges than TKA patients younger than 85 yrs (P = 0.042). THA patients > or =85 yrs had 6-10% lower total FIM, FIM motor, and FIM cognition scores and were discharged to home less frequently than younger patients (P < 0.05). Total and daily charges were 21-162% higher in THA patients with BMIs > or =50 kg/m than in THA patients with BMIs <50 kg/m (P < 0.045). CONCLUSION: All patients made functional gains during rehabilitation. However, the most costly and lengthy rehabilitation occurred in TKA patients > or =85 yrs and THA patients with BMI > or =50 kg/m.     

Outcomes in total knee arthroplasty patients after inpatient rehabilitation: influence of age and gender

OBJECTIVES: To examine age and gender effects on outcomes after inpatient rehabilitation in primary total knee arthroplasty (TKA) and revision TKA patients. DESIGN: This retrospective, comparative study was conducted in a 50-bed, university-affiliated rehabilitation hospital. Patients included primary TKA patients (n = 286) and revision TKA patients (n = 138) placed into one of three age brackets: <60 yrs, 60-70 yrs, or >70 yrs. Measurements included length of stay (LOS), FIM scores, hospital charges, and discharge disposition location. RESULTS: FIM scores improved from admission to discharge in both primary and revision patients (P = 0.015). LOS was shorter in primary than revision patients (8.3 vs. 10.4 days, P = 0.001), and the LOS was longest in patients >70 yrs compared with those <60 or 60-70 yrs (10.6 vs. 8.7 and 8.8 days, respectively; P = 0.004). FIM efficiency was greater in primary than in revision TKA patients (3.68 vs. 2.77 points/day, P = 0.001), and greater for men than women in each age bracket regardless of TKA type (3.68 vs. 2.78 points/day, P = 0.001). Total hospital charges were lower for men than women for both TKA types ($9,656 +/- 823 vs. $11,544 +/- 1,359; P = 0.015), and were highest in patients >70 yrs of age (P = 0.015). CONCLUSIONS: Primary and revision TKA patients make improvements in functional independence during inpatient rehabilitation. Although FIM gains were similar among age and gender groupings, FIM efficiency is lowest in women. Despite similar daily hospital costs among the groups, slower progress with functional gains (decreased FIM efficiency) increases the LOS and total hospital charges, especially in older women.     

Sex and age effects on outcomes of total hip arthroplasty after inpatient rehabilitation

OBJECTIVE: To retrospectively examine the effects of sex and age on the inpatient rehabilitation outcomes of patients after total hip arthroplasty (THA). DESIGN: Exploratory, retrospective study. SETTING: A university-affiliated rehabilitation hospital. PARTICIPANTS: Male and female THA patients (N=332) were stratified into age brackets (<65y, 65-84y, >or=85y). All patients completed interdisciplinary inpatient rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Length of stay (LOS), FIM instrument scores, FIM efficiency (FIM/LOS), hospital costs, and discharge disposition location were collected by chart review. RESULTS: Regardless of age, women had lower FIM scores at admission and discharge than men (P<.05). FIM efficiency was 22% to 53% lower for women in primary THA and 16% to 85% lower in revision THA than men (P=.001). Women accrued higher total hospital charges than men (13,099 dollars vs 11,141 dollars; P<.05), and were discharged home less frequently than men (84.4% vs 90.9%; P<.05). Admission FIM scores were 10.6% and 8.9% lower and discharge FIM scores were 7.3% and 9.2% lower in patients 85 years or older than those less than 65 or 65 to 84 years (P<.01). FIM efficiency was 25% to 38% higher in patients less than 85 years than those 85 years and older (P=.015), and 37% higher in men than women (P=.001). Patients 85 years and older were discharged less frequently to home than patients less than 85 years (P<.05). CONCLUSIONS: All patients made functional improvement after inpatient rehabilitation, but women and patients 85 years and older had longer LOS and lower FIM efficiency, incurred greater hospital charges, and were less likely to be discharged to home than men and younger counterparts.     

Effect of obesity on inpatient rehabilitation outcomes following total knee arthroplasty

OBJECTIVES: To examine obesity effects on outcomes following inpatient rehabilitation in patients following primary total knee arthroplasty or revision total knee arthroplasty. DESIGN: Retrospective, comparative study. SETTING: Fifty-bed, university-affiliated rehabilitation hospital. PATIENTS: Obese (N = 139; body mass index >30 kg/m(2)) and non-obese (N = 146; body mass indexB <30 kg/m(2)) total knee arthroplasty patients. Participants were further stratified based on total knee arthroplasty type, primary and revision for a total of four groups. INTERVENTION: Interdisciplinary inpatient rehabilitation. MAIN MEASURES: Range of motion, length of stay, Functional Independence Measure (FIM) scores, FIM efficiency scores, total and daily hospital charges, and discharge disposition location. RESULTS: Range of motion and FIM scores improved from admission to discharge in both obese and non-obese patients regardless of total knee arthroplasty type. FIM efficiency was lower in revision than primary total knee arthroplasty (2.8 versus 3.6 patients/day; P < 0.005) but not different between obese and non-obese groups. Total hospital charges were lower for the primary than for the revision patients (P < 0.05), but were directly related with body mass index (r = 0.140, P < 0.05). Discharge disposition locations were not different among groups. CONCLUSION: Rehabilitation teams can expect comparable gains between obese and non-obese patients following total knee arthroplasty, but at a greater expense.     

Outcomes after inpatient rehabilitation of primary and revision total hip arthroplasty

OBJECTIVE: To compare the outcomes of patients who have gone to inpatient rehabilitation after primary total hip arthroplasty (THA) and revision THA. DESIGN: Retrospective, comparative study. SETTING: Fifty-bed freestanding, university-affiliated rehabilitation hospital. PARTICIPANTS: Two hundred fifty-five male and female primary THA patients and 147 male and female revision THA patients. INTERVENTION: Interdisciplinary inpatient rehabilitation. MAIN OUTCOME MEASURES: Length of stay (LOS), FIM instrument score and FIM motor score components, hospital charges, and discharge disposition location. RESULTS: FIM scores improved from admission to discharge by 29.7 and 27.9 points for the primary THA and revision THA groups, respectively (P<.05). LOS was shorter for primary THA patients compared with revision THA patients (10.0d vs 11.5d, P<.05). FIM efficiency (DeltaFIM/LOS) was greater for primary THA compared with revision THA (3.4 and 2.7 points/day, P<.05). Total rehabilitation hospital charges were 11,421 US dollars and 13,707 US dollars for the primary and revision THA groups, respectively, with the mechanical and infection revision THAs incurring the greatest charges (14,596 US dollars and 15,386 US dollars, respectively; P<.001). Compared with primary THA, revision THA patients were twice as likely to be discharged to locations other than home. CONCLUSIONS: FIM score improvement was lower and LOS and hospital charges were greater in revision THA than in primary THA after rehabilitation. Infection revision THA patients gained less functional independence and were discharged home less often than mechanical or pain revision THA patients; finally, infection and mechanical revision THA accrued the highest hospital charges.     

Venous thromboembolism in a rehabilitation setting after major lower-extremity amputation

OBJECTIVE: To determine the prevalence of venous thromboembolic disease (VTED) and impact on functional outcome in patients with major lower-extremity (LE) amputation admitted to an inpatient rehabilitation unit. DESIGN: Retrospective medical records review. SETTING: Acute inpatient rehabilitation unit in a tertiary, urban academic medical center. PARTICIPANTS: Fifty consecutive patients admitted to an acute inpatient rehabilitation unit after a major LE amputation. Participants were screened at rehabilitation admission for LE deep vein thrombosis using duplex ultrasonography. INTERVENTIONS: Not applicable.Main outcome measures VTED incidence, FIM instrument, total rehabilitation charges, and length of stay (LOS). RESULTS: Six of 50 patients (12%) had evidence of VTED. The VTED cohort had significantly lower admission and discharge FIM scores than the no-VTED cohort (admission FIM score, 57.2 vs 76.0; discharge FIM score, 66.0 vs 90.1, respectively; P< or =.02). Subjects with VTED had a longer rehabilitation LOS (22.8d vs 13.9d, respectively; P=.02) and higher total rehabilitation charges (28,314 US dollars vs 17,724 US dollars, respectively; P<.05). CONCLUSIONS: In this study, VTED prevalence after LE amputation in a rehabilitation setting was 12%. Subjects with VTED had lower admission and discharge functional status, longer LOS, and higher hospital charges. The utility of screening duplex ultrasound examinations at rehabilitation admission remains unclear.     

Poster 7: Impact of balance deficits after traumatic brain injury on inpatient rehabilitation functional outcome: a multicenter study

Objective: To evaluate how sitting and standing balance ratings of patients with traumatic brain injury (TBI) on admission to rehabilitation impacts functional outcome, rehabilitation charges, and rehabilitation length of stay (LOS). Design: Multicenter analysis of consecutive admissions to designated Traumatic Brain Injury Model Systems (TBIMS). Setting: TBIMS centers. Participants: 908 adults with TBI were included in the study. Interventions: Not applicable. Main Outcome Measure: FIM™ instrument admission and discharge scores, FIM change and efficiency; rehabilitation LOS and charges; and discharge disposition. Results: Persons with grossly impaired sitting balance on admission to rehabilitation had lower discharge FIM scores and greater rehabilitation charges than those with normal or mildly impaired sitting balance. Persons with mildly impaired sitting balance had lower discharge FIM scores and greater rehabilitation charges than those with normal sitting balance. Subjects with grossly impaired standing balance compared with normal or mildly impaired standing balance had greater rehabilitation charges and LOS and lower discharge FIM scores and FIM efficiency. Subjects with grossly impaired balance on admission to rehabilitation had significantly lower motor FIM items compared with those who had normal or mildly impaired balance. Subjects with grossly impaired sitting balance were discharged from rehabilitation to someplace other than their home more than twice as often as those with normal sitting balance (11.7% vs 23.3%). Subjects with grossly impaired standing balance were discharged from rehabilitation to someplace other than their home more than 3 times as often as subjects with normal standing balance (6.7% vs 21.5%). Conclusion: In patients with TBI, sitting and standing balance ratings on admission to rehabilitation are useful indicators of functional impairment and not returning home at discharge from rehabilitation.     

Vitamin D status of patients admitted to a hospital rehabilitation unit: relationship to function and progress

OBJECTIVE: The primary objective was to determine the association between vitamin D status, baseline function, and short-term inpatient rehabilitation progress. DESIGN: This was a prospective convenience sampling of 100 patients in a tertiary general hospital rehabilitation unit (RU). The cohort comprised men and women of mixed race with a variety of diagnoses (mean age 70 yrs). Patient histories and demographic information were obtained by patient interview and chart review. Serum 25-hydroxyvitamin D (25OHD) (nmol/L) was measured on or after the day of admission. The Functional Independence Measurement (FIM) instrument, a validated survey tool, was used to measure function at admission and discharge. RESULTS: Eleven percent of the patients were overtly vitamin D deficient, with serum 25OHD concentrations <20 nmol/L. Ninety-four percent of the patients had serum 25OHD concentrations below the recommended minimum optimal concentration of 80 nmol/L. Using the Spearman rank correlation test, low serum 25OHD was weakly but significantly associated with low total FIM scores: r = 0.25 (P < 0.012) and r = 0.23 (P < 0.021) for admission and discharge total FIM score, respectively. Patients with serum 25OHD concentrations greater than the median value of 41.3 nmol/L had significantly higher FIM efficiency scores (discharge total FIM score - admission total FIM score/length of stay [LOS]) than the subgroup of patients below the median (2.0 +/- 1.1 vs. 1.6 +/- 0.9, respectively; P < or = 0.026). Serum 25OHD was not significantly correlated with FIM efficiency or the unadjusted change in total FIM score (discharge total FIM score - admission total FIM score), but it was significantly correlated with LOS (the lower the serum 25OHD concentration, the longer the LOS, and vice versa; r = -0.235, P < 0.018). Thus, the difference in FIM efficiency between patients with serum 25OHD above and below the median was the result of the significant inverse correlation between serum 25OHD and LOS; as a group, patients with serum 25OHD above the median had a 19% shorter LOS than the group with serum 25OHD below the median value (11.4 +/- 4.9 vs. 14.1 +/- 5.6 days, respectively; P = 0.005). CONCLUSIONS: Most patients in a hospital RU had a suboptimal serum 25OHD concentration, reflecting what has previously been observed in hospitalized patients in general and also the population at large. Although no specific physical deficits or attributes could be directly attributed to low serum 25OHD, the baseline functional status of RU patients, LOS, and progress attributable to inpatient rehabilitation (FIM efficiency) were favorably affected by higher serum 25OHD concentrations.     

Analysis of FIM instrument scores for patients admitted to an inpatient cardiac rehabilitation program

OBJECTIVE: To evaluate in an inpatient cardiac rehabilitation program (a phase IB) whether length of stay (LOS), discharge to home, and improvement in physical function differed between patients with lower and higher degrees of functional independence on admission. DESIGN: A retrospective study. SETTING: A public acute long-term care hospital. PATIENTS: All cardiac rehabilitation patients (N = 143) admitted to the hospital from January 1998 through June 1999. Patients were divided into a higher- and a lower-functioning group by using the admission FIM instrument scores above and below the midpoint of 72. Comparisons in LOS, discharge disposition, and functional gains between these 2 groups were then performed. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: FIM scores, FIM change, FIM gains per week, LOS, and discharge disposition. RESULTS: Total FIM scores at discharge were significantly higher than those on admission (25%, P <.0001). The median value of total FIM gains per week was 7.78 with a stay of 17 days and a home discharge rate of 76%. The higher-functioning group (n = 106) differed from the lower group (n = 37) with shorter stay (15 vs 23d, P <.0001), greater FIM gains per week (8.6 vs 4.8, P =.002), and greater likelihood of discharge to home or community (84% vs 54%, P <.001). The average incremental FIM change in each group was the same. In multivariate analysis, both admission (P =.001) and discharge (P <.001) FIM scores were the best predictors of patients' discharge disposition to home. CONCLUSIONS: Admission FIM scores are important predictors for the clinical course and discharge outcomes of cardiac rehabilitation patients, with those with higher admission FIM scores having a shorter LOS and greater likelihood of discharge to home. The admission FIM scores can help to establish realistic goals.     

A follow-up study of older adults with traumatic brain injury: taking into account decreasing length of stay

OBJECTIVE: To examine age-related differences in rehabilitation outcomes following traumatic brain injury (TBI). DESIGN: Retrospective collaborative study. SETTING: Patients received acute neurotrauma and inpatient rehabilitation services at 1 of the 17 National Institute on Disability and Rehabilitation Research-designated Traumatic Brain Injury Model Systems (TBIMS) centers. PARTICIPANTS: A sample of 273 older patients (> or =55y) admitted for TBI were taken from the TBIMS National Database. Older patients were matched with subjects 44 years of age or younger, based on severity of injury (Glasgow Coma Scale score, length of coma, intracranial pressure elevations). Due to decreasing length of stay (LOS), only patients admitted from 1996 through 2002 were included. INTERVENTION: Inpatient interdisciplinary brain injury rehabilitation. MAIN OUTCOME MEASURES: Acute care LOS, inpatient rehabilitation LOS, admission and discharge FIM instrument and Disability Rating Scale (DRS) scores, FIM and DRS efficiency, acute and rehabilitative charges, and discharge disposition. RESULTS: One-way analyses of variance demonstrated a statistically significant difference between older and younger patients with respect to LOS in rehabilitation but not for acute care. Total rehabilitative charges, and admission and discharge DRS and FIM scores also showed statistically significant differences between groups. Older patients progressed with significantly less efficiency on both the DRS and FIM scales. Significantly more charges were generated per unit for older patients to improve on the DRS scale, but not the FIM scale. Using chi-square analysis, a statistically significant difference in rate of discharge to home was identified between older (80.5%) and younger (94.4%) patients. CONCLUSIONS: Results in this study are similar to those in earlier studies with smaller sample sizes. Major differences observed include significantly slower and more costly progress in inpatient rehabilitation for older patients with TBI, as well as a significantly lower rate of discharge to community for older patients. However, even with decreasing LOS in both settings, community discharge rate is still encouraging for older patients with TBI.     

Gender-related differences in acute rehabilitation lengths of stay, charges, and functional outcomes for a matched sample with spinal cord injury: a multicenter investigation

OBJECTIVE: To examine the effects of gender on length of stay (LOS), treatment costs, and outcomes by using a matched sample of patients with spinal cord injury (SCI). DESIGN: A 2 x (15 x 3) mixed, block design was used retrospectively to analyze the impact of gender on subjects matched for age, American Spinal Injury Association (ASIA) motor impairment classification, and level of neurologic injury. SETTING: Twenty medical centers in the federally sponsored Spinal Cord Injury Model Systems project. PARTICIPANTS: One thousand seventy-four adult patients with SCI admitted between 1988 and 1998 were assessed at acute-care admission, inpatient rehabilitation admission, and inpatient rehabilitation discharge. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: ASIA motor index and FIM instrument admission, discharge, and efficiency scores; rehabilitation LOS and medical care charges; and discharge disposition. RESULTS: Analysis revealed no gender-related differences in FIM motor scores on admission and discharge. No differences in FIM motor efficiencies or daily change were observed. No significant differences were found for ASIA motor scores on acute-care admission and rehabilitation discharge. No differences in acute rehabilitation LOS and charges were observed. No gender-related differences were seen in the likelihood of discharge to an institutional setting. CONCLUSION: Gender was not a significant factor in functional outcome of SCI patients after acute rehabilitation.     

Significance of poor patient participation in physical and occupational therapy for functional outcome and length of stay

OBJECTIVES: To determine the frequency of poor patient participation during inpatient physical (PT) and occupational therapy (OT) sessions and to examine the influence of poor participation on functional outcome and length of stay (LOS). DESIGN: Prospective observational study. SETTING: University-based, freestanding acute rehabilitation hospital. PARTICIPANTS: Two hundred forty-two inpatients, primarily elderly (age range, 20-96y), with a variety of impairment diagnoses (eg, stroke), who were admitted for inpatient rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Pittsburgh Rehabilitation Participation Scale, the 13 motor items from the FIM instrument (FIM motor), LOS, and discharge disposition. RESULTS: We categorized the sample into 3 groups: "good" participators were those for whom all inpatient PT and OT sessions were rated 4 or greater (n=139), "occasional poor" participators were those with less than 25% of scores rated below 4 (n=53), and "frequent poor" participators were those with 25% or more of scores rated below 4 (n=50). Change in FIM motor scores during the inpatient rehabilitation stay was significantly better for good and occasional poor participators, compared with frequent poor participators (mean FIM improvement: 23.2, 22.8, and 17.6, respectively; repeated-measures analysis of variance group by time interaction, P <.002). LOS was significantly longer for occasional poor participators, compared with good and frequent poor participators controlling for admission FIM differences (adjusted means: 13.9d, 11.0d, and 10.9d, respectively; analysis of covariance, P <.001). CONCLUSIONS: Poor participation in therapy is common during inpatient rehabilitation and has important clinical implications, in terms of lower improvement in FIM scores and longer LOS. These results suggest that poor inpatient rehabilitation participation and its antecedents deserve further attention.     

Association of hemoglobin levels, acute hemoglobin decrease, age, and co-morbidities with rehabilitation outcomes after total knee replacement

OBJECTIVE: A study was undertaken to assess the association of preoperative and postoperative hemoglobin levels with rehabilitation outcomes, age, and selected co-morbidities DESIGN: Charts of 49 patients admitted to rehabilitation after total knee arthroplasty due to degenerative joint disease were reviewed. Outcome measures included rehabilitation admission and discharge motor FIMtrade mark scores, motor FIM gain, and rehabilitation length of stay. RESULTS: Patients with higher preoperative hemoglobin levels had higher rehabilitation admission motor FIM scores (r=0.38, P<0.01) and lower motor FIM gains (r=-0.45, P<0.001). Patients who had higher hemoglobin levels at rehabilitation admission had higher admission motor FIM scores and shorter length of stay. Patients with diabetes had lower preoperative hemoglobin levels. Patients with hypertension had longer length of stay. Older patients had lower admission and discharge motor FIM scores and longer length of stay. CONCLUSIONS: Patients admitted to rehabilitation after total knee replacement have the potential to improve motor function, regardless of their preoperative and rehabilitation admission hemoglobin levels and the decrease in hemoglobin levels. However, those admitted to rehabilitation with lower hemoglobin levels, those with lower admission motor FIM scores, those who are older, and those who have hypertension may expect longer hospital stays to reach their functional goals.     

Outcomes of early surgical management versus late or no surgical intervention after acute spinal cord injury

OBJECTIVE: To compare neurologic, medical, and functional outcomes of patients with acute spinal cord injury (SCI) undergoing early (<24 h and 24-72 h) and late (>72 h) surgical spine intervention versus those treated nonsurgically. DESIGN: Retrospective case series comparing outcomes by surgical and nonsurgical groups during acute care, rehabilitation, and at 1-year follow-up. SETTING: Multicenter National Spinal Cord Injury Database. PARTICIPANTS: Consecutive patients with acute, nonpenetrating, traumatic SCI from 1995 to 2000, admitted in the first 24 hours after injury. Surgical spinal intervention was likely secondary to nature of injury and the need for spinal stabilization. Interventions Not applicable. MAIN OUTCOME MEASURES: Changes in neurologic outcomes (motor and sensory levels, motor index score, American Spinal Injury Association [ASIA] Impairment Scale [AIS]), medical complications (pneumonia and atelectasis, deep vein thrombosis and pulmonary embolism, pressure ulcers, autonomic dysreflexia, rehospitalization), and functional outcomes (acute and rehabilitation length of stay [LOS], hospital charges, FIM instrument score, FIM motor efficiency scores). RESULTS: Subjects in the early surgery group were more likely ( P <.05) to be women, have paraplegia, and have SCI caused by motor vehicle collisions. The nonsurgical group was more likely ( P <.05) to have an older mean age and more incomplete injuries. ASIA motor index improvements (from admission to 1-y follow-up) were more likely ( P <.05) in the nonsurgical groups, as compared with the surgical groups. Those with late surgery had significantly ( P <.05) increased acute care and total LOS and hospital charges along with higher incidence of pneumonia and atelectasis. No differences between groups were found for changes in neurologic levels, AIS grade, or FIM motor efficiency. CONCLUSIONS: ASIA motor index improvements were noted in the nonsurgery group, though likely related to increased incompleteness of injuries within this group. Early versus late spinal surgery was associated with shorter LOS and reduced pulmonary complications, however, no differences in neurologic or functional improvements were noted between early or late surgical groups.     

Neoplastic versus traumatic spinal cord injury: an outcome comparison after inpatient rehabilitation.

OBJECTIVE: To compare outcomes of patients with neoplastic spinal cord compression (SCC) to outcomes of patients with traumatic spinal cord injury (SCI) after inpatient rehabilitation. DESIGN: A comparison between patients with a diagnosis of neoplastic SCC admitted to an SCI rehabilitation unit and patients with a diagnosis of traumatic SCI admitted to the regional Model Spinal Cord Injury Centers over a 5-year period, controlling for age, neurologic level of injury, and American Spinal Injury Association impairment classification. SETTING: Tertiary university medical centers. PATIENTS: Twenty-nine patients with neoplastic SCC and 29 patients with SCI of traumatic etiology who met standard rehabilitation admission criteria. MAIN OUTCOME MEASURES: Acute and rehabilitation hospital length of stay (LOS), Functional Independence Measure (FIM) scores, FIM change, FIM efficiency, and discharge rates to home. RESULTS: Patients with neoplastic SCC had a significantly (p < .01) shorter rehabilitation LOS than those with traumatic SCI (25.17 vs 57.46 days). No statistical significance was found in acute care LOS. Motor FIM scores on admission were higher in the neoplastic group, but discharge FIM scores and FIM change were significantly lower. Both groups had similar FIM efficiencies and community discharges. CONCLUSIONS: Patients with neoplastic SCC can achieve rates of functional gain comparable to those of their counterparts with traumatic SCI. While patients with traumatic SCI achieve greater functional improvement, patients with neoplastic SCC have a shorter rehabilitation LOS and can achieve comparable success with discharge to the community.     

The impact of previous strokes on the rehabilitation of elderly patients sustaining a hip fracture

OBJECTIVE: To evaluate whether a previous stroke may affect the functional outcome gain of elderly patients undergoing rehabilitation for a hip fracture. DESIGN: A retrospective cohort study. SETTING: The division of geriatric medicine with rehabilitation wards at a university-affiliated referral hospital. PARTICIPANTS: Patients with hip fractures (N=460) undergoing a standard rehabilitation course. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The functional outcome of previous stroke- and nonprevious stroke (NPS)-affected patients assessed by the FIM instrument at admission and discharge from the rehabilitation facility. Data were analyzed by t tests, Pearson correlation, chi-square tests, and linear regression analysis. RESULTS: Both admission and discharge total FIM scores were significantly higher in NPS compared with previous stroke patients (63.53+/-19.89 vs 52.19+/-19.37, P<.001) and (84.23+/-24.93 vs 71.37+/-25.03, P=.001), respectively. However, changes in total FIM (20.70+/-11.68 vs 19.17+/-13.32, P=.38) and in motor FIM (19.84+/-10.63 vs 17.96+/-11.21, P=.23) at discharge were not statistically significant between the 2 groups. A linear regression analysis showed that a previous stroke was not predictive of a worse total FIM gain at discharge (P=.58). CONCLUSIONS: NPS hip fracture elderly patients show higher admission and discharge FIM scores compared with previous stroke patients. Nevertheless, both groups achieve similar FIM gains during rehabilitation period. A previous stroke should not be considered as adversely affecting the rehabilitation of such patients.

背景随着社会的发展和进步,生活质量越来越得到重视,在功能独立性评定的基础上,增加对生活质量的评定是必然的趋势.目的探讨功能独立性评定和生活质量评定在康复临床中的结合应用.设计病例分析.单位复旦大学中山医院.对象选择2003-01/12中山医院康复科病房住院患者83例,其中男45例,女38例.根据疾病分为以下4组[1]骨关节康复组42例.[2]脑卒中康复组17例.[3]内科康复组15例.[4]肿瘤康复组9例.患者均自愿参加本实验.方法每例患者在出入院24 h内进行功能独立性和生活质量的评定,功能独立性量表采用功能独立性问卷评定(包括13项运动方面内容,5项认知方面内容.运动类活动总分最低为13分,最高为91分;认识类活动总分最低为5分,最高为35分;功能独立性问卷总分最低为18分,最高为126分),生活质量采用功能活动问卷进行评定(包括打电话、自理经济、购物、使用交通工具、做家务、工作、参加娱乐性活动等,总分100分),每份问卷均由作者亲自填写.主要观察指标各组患者在出入院时功能独立性评分和功能活动问卷评分.结果83例患者均进入结果分析.[1]脑卒中组的平均年龄和住院时间明显高于其他组(P＜0.01).[2]脑卒中组出院时功能独立性运动分、认知分明显高于入院时(5.276,3.624分;6.200,5.941分,P＜0.01).功能活动问卷评分明显低于入院时(1.253,1.547分,P＜0.01).[3]骨关节组出入院功能独立性认知分基本一致,出院时运动分明显高于入院时(6.220,5.388分,P＜0.01).功能活动问卷评分明显低于入院时(0.610,0.912分,P＜0.01).[4]肿瘤组只有能活动问卷评分明显低于入院时(0.722,0.989分,P＜0.05).[5]内科组的所有项目出入院评分基本一致(P＞0.05).结论在康复临床中功能活动问卷评分比功能独立性评分更敏感,但并不能取代功能独立性评分,应该结合使用.     

FIM量表在外伤性颅脑损伤患者康复疗效评价中的应用

目的 :运用功能独立性评价量表 (FIM )评价外伤性颅脑损伤 (TBI)患者的康复治疗疗效 ,比较闭合性颅脑损伤 (CBI)和开放性颅脑损伤 (OBI)患者的临床特点和康复治疗的效果。方法 :79例TBI患者中 ,5 7例为CBI、2 2例为OBI。运用FIM量表评价两组患者康复治疗前后的功能情况 ,统计患者的入院天数 ,计算FIM效率。结果 :CBI和OBI患者入院时的FIM总评分分别为 81.5 1和 73.0 9;出院时FIM总评分分别为 115 .0 4和 117.77,两组平均增加 4 1%和 5 3%。两组患者康复治疗前后FIM各项评分自身相比有非常显著差异 (P <0 .0 0 1) ,但两组之间相比无显著差异。两组患者的FIM效率分别为 1.99分 /天和 1.71分 /天。结论 :康复治疗可有效改善TBI(无论是CBI还是OBI)患者的功能情况。康复治疗应强调早期和综合性治疗
