ABSTRACT

STUDY DESIGN: Psychometric study. OBJECTIVES: The objective of this study was to examine the reliability of the Spinal Cord Independence Measure III (SCIM III) by interview and compare the findings with those of assessment by observation. SETTING: This study was conducted at Loewenstein Rehabilitation Hospital, Israel. METHODS: Thirty-five spinal cord lesion (SCL) patients who underwent rehabilitation at Loewenstein Rehabilitation Hospital in Israel were assessed during the last week before discharge with SCIM III by observation and by interview. Nineteen of the patients were also assessed by interview by a third rater to examine inter-rater reliability. Total agreement, kappa, Bland-Altman plots and intraclass correlation (ICC) were used for comparison between interviewers and between interviews and observations. RESULTS: Total agreement between the interviewers' scores and between interviews and observations was low to moderate (kappa coefficient 0.11-0.80). Bland-Altman analysis revealed good agreement, with low mean difference for almost all SCIM III subscales and total scores, between pairs of interviewers (bias -4.15, limits of agreement -22.51 to 14.19, for total score) and between interviews and observations (bias 1.62, limits of agreement -20.55 to 23.81, for total score). ICC coefficients for the SCIM III subscales and total scores were high (0.637-0.916). CONCLUSION: The findings of this study support the reliability and validity of SCIM III by interview, which appears to be useful for research of SCL patient groups. Individual scoring of SCIM III by interview, however, varied prominently between raters. Therefore, SCIM III by interview should be used with caution for clinical purposes, probably by raters whose scoring deviation, in relation to observation scores, is known.

ABSTRACT

STUDY DESIGN: Retrospective observational comparative study. OBJECTIVES: The objectives of this study were to assess the atherosclerosis diseases and risk factors prevalence after spinal cored injury (SCI). SETTING: Loewenstein Rehabilitation Hospital, Israel. METHODS: Data of 154 traumatic and non-traumatic SCI patients were retrospectively collected. Coronary artery disease (CAD), myocardial infarction (MI), hypertension (HT) and risk factors for atherosclerotic diseases were examined after SCI for prevalence and effects, and compared with published corresponding data of the general population. RESULTS: CAD, MI and HT were found in 11.7, 6.7 and 29.2% of 120 patients, aged 53.4±11.1 years, 83.3% males, who survived until the end of the follow-up. Corresponding values for the general population, adjusted for age, gender and years of education, are 8.5, 6.6 and 24.9% in Israel, and 10.2% for CAD and 40.3% for HT, in US. Body mass index>30 increased the odds of acquiring CAD (P=0.016). Hypercholesterolemia and older age at injury increased the hazard for HT (P=0.044; P=0.019, respectively). A steady partner decreased the risk of CAD (P=0.029). HT was more prevalent at T4-T6 than above T4 (52 vs 23.3%, P=0.02). Patients with SCI below T6 had a higher rate of diabetes mellitus, hypercholesterolemia, and past smoking, and fewer years of education than those with SCI above T7 (P=0.016; P=0.032; P=0.034; P=0.014, respectively). CONCLUSION: The prevalence of CAD, HT and some of their risk factors after SCI is generally, but not consistently and not statistically significant, slightly higher than in the corresponding general population. The challenge is to reduce the prevalence of atherosclerotic morbidity after SCI below that in the general population.

ABSTRACT

STUDY DESIGN: The spinal cord injury ability realization measurement index (SCI-ARMI) assesses rehabilitation potential and efficacy based on the linear relationship between the Spinal Cord Independence Measure (SCIM) and the American Spinal Injury Association impairment scale (AIS) motor scores (AMS). OBJECTIVES: The objective of this study is to develop new SCI-ARMI formulas using a more flexible approach that is less sensitive to the distribution of the AMS score among spinal cord lesion (SCL) patients. SETTING: Loewenstein Rehabilitation Hospital, Raanana, and the Statistical Laboratory, School of Mathematics, Faculty of Exact Sciences, Tel-Aviv University, Israel. METHODS: SCIM III and AMS of 226 Israeli SCL patients were monitored. Linear formulas, quadratic formulas and non-parametric formulas were estimated to express the relationship between the 95th percentile of the SCIM III values for patients with given AMS at discharge from rehabilitation (SCIM95) and the corresponding AMS value. This relationship was used to calculate SCI-ARMI values, defined as the ratio of the observed SCIM score and the respective SCIM95 for a given patient's AMS score. RESULTS: The estimated quadratic formula for the relationship between the 95th percentile of the SCIM III and the AMS score was found to be most appropriate, and formulas are provided for SCIM95 calculation in the various areas of function. The use of these formulas to calculate SCI-ARMI values is presented. CONCLUSION: The new formulas improve the accuracy of calculated ability realization for any AMS. The new statistical procedure will be used for the upcoming data analysis of a larger-scale international SCI-ARMI study.

ABSTRACT

BACKGROUND: Disability scales do not enable the transmission of concise, meaningful and daily function description for clinical purposes. STUDY DESIGN: Cross-sectional statistical analysis of 328 patients' Spinal Cord Independence Measure (SCIM) III item scores (SIS). OBJECTIVE: To develop a concise and clinically interpretable data-based characterization of daily task accomplishment for patients with spinal cord lesions (SCLs). SETTING: Multi-center study at 13 spinal units in 6 countries. METHODS: Patients were grouped into clusters characterized by smaller differences between the patients' SIS within the clusters than between their centers, using the k-medoides algorithm. The number of clusters (k) was chosen according to the percent of SIS variation they explained and the clinical distinction between them. RESULTS: Analysis showed that k=8 SIS clusters offer a good description of the patient population. The eight functional clusters were designated as A-H, each cluster (grade) representing a combination of task accomplishments. Higher grades were usually (but not always) associated with patients implementing more difficult tasks. Throughout rehabilitation, the patients' functional grade improved and the distribution of patients with similar functional grades within the total SCIM III score deciles remained stable. CONCLUSIONS: A new classification based on SIS clusters enables a concise description of overall functioning and task accomplishment distribution in patients with SCL. A software tool is used to identify the patients' functional grade. Findings support the stability and utility of the grades for characterizing the patients' functional status.

ABSTRACT

STUDY DESIGN: Multicenter international cohort study. OBJECTIVE: The objective of this study was to establish target values for Spinal Cord Independence Measure (SCIM) III scoring in rehabilitation for clinically complete spinal cord lesion (SCL) neurological levels. SETTING: In total, 13 spinal cord units in six countries from North America, Europe and the Middle East were taken. METHODS: Total SCIM III scores and gain at discharge from rehabilitation were calculated for SCL levels in 128 patients with American Spinal Injury Association Impairment Scale (AIS) grade A on admission to rehabilitation. RESULTS: Median, quartiles, mean and s.d., values of discharge SCIM III scores and SCIM III gain for the various SCL levels are presented. Total SCIM III scores and gain were significantly correlated with the SCL level (r=0.730, r=0.579, P<0.001). CONCLUSIONS: Calculated discharge SCIM III scores can be used as target values for functional achievements at various neurological levels in patients after AIS A SCL. They are generally, but not always, inversely correlated with SCL level.

ABSTRACT

STUDY DESIGN: A multi-center international cohort study. OBJECTIVE: To evaluate the reliability and validity of the third version of the Spinal Cord Independence Measure (SCIM III), separately for patients with traumatic spinal cord lesions (SCLs). SETTING: A total of 13 spinal cord units in six countries from North America, Europe and the Middle-East. METHODS: SCIM III and Functional Independence Measure (FIM) were assessed for 261 patients with traumatic SCLs, on admission to rehabilitation and before discharge, by two raters. Conventional statistical measures were used to evaluate the SCIM III reliability and validity. RESULTS: In almost all SCIM III tasks, the total agreement between the paired raters was >80%. The κ coefficients were all >0.6 and statistically significant. Pearson's coefficients of the correlations between the paired raters were >0.9, the mean differences between raters were nonsignificant and the intraclass correlation coefficients (ICCs) were ≥ 0.95. Cronbach's α values for the entire SCIM III scale were 0.833-0.835. FIM and SCIM III total scores were correlated (r=0.84, P<0.001). SCIM III was more responsive to changes than FIM. In all subscales, SCIM III identified more changes in function than FIM, and in 3 of the 4 subscales, differences in responsiveness were statistically significant (P<0.02). CONCLUSION: The results confirm the reliability and validity of SCIM III for patients with traumatic SCLs in a number of countries.

ABSTRACT

DESIGN: A retrospective cohort study. OBJECTIVE: Assess outcomes in patients with spinal cord injuries (SCI) following road accidents, and factors that affect them. SETTING: Loewenstein Rehabilitation Hospital, Raanana, Israel. SUBJECTS: A total of 143 patients admitted for rehabilitation between 1962 and 2004. METHODS: Survival rates were estimated using the product limit (Kaplan-Meyer) method and their association with risk factors was analyzed with the Cox model. Neurological recovery was determined by comparing the Frankel grade at admission to rehabilitation and at discharge. The relation between recovery and various factors was tested with logistic regression. RESULTS: The risk of SCI in road accidents is higher among car drivers and motorcycle or bicycle riders. Median survival was 43 years. Survival was negatively associated with age at injury (P<0.0002) and with diagnosis of pressure sores (P=0.0065). Recovery of at least one Frankel grade occurred in 29.1% of patients. Useful recovery (upgrade to Frankel grade D or E) occurred in 23.1% of all patients. Neurological recovery was negatively associated with the severity of neurological deficit (P<0.001) and with thoracic injuries (P=0.046). The most common complications were pressure sores and those of the urinary and respiratory systems. CONCLUSIONS: In SCI following road accidents, survival rates were higher and recovery rates lower than in mixed types of trauma. This may be related to better compensation followed by better nursing for road accident victims in Israel, which may prevent life-shortening complications, and to more severe injuries caused by road accidents.
