- Abstract
Objective: We sought to assess whether outcomes and reimbursement differ for Medicare beneficiaries with hip fracture when treated in an inpatient rehabilitation facility (IRF) compared with a skilled nursing facility (SNF) subacute rehabilitation program.Participants: Clinical data were linked with Medicare claims for 29,793 Medicare fee-for-service beneficiaries with a recent hip fracture who completed treatment in 1996 or 1997 in rehabilitation facilities that subscribed to the Uniform Data System for Medical Rehabilitation.Outcome Measures: We measured discharge destination, change in motor FIM rating, and Medicare Part A reimbursement.Results: For patients with moderate-to-severe and severe disabilities, case mix groups (CMGs) 704 and 705, the percentage of patients discharged to the community from IRFs was lower than for patients treated in subacute rehabilitation SNFs, after controlling for covariates. Adjusted odds ratios were 0.71 (95% confidence interval 0.55-0.92) for CMG 704 and 0.72 (95% confidence interval 0.63-0.83) for CMG 705. For patients in the 3 other CMGs, no significant differences were detected. Improvement in motor functional status was roughly equivalent for patients treated in IRFs and those treated in the subacute rehabilitation programs across all 5 CMGs, after controlling for covariates. Medicare Part A payments for IRFs were significantly higher than SNF payments across all CMGs.Conclusion: SNF-based subacute rehabilitation was less costly and outcomes were in most, but not all, instances similar or better than IRF-based rehabilitation for Medicare fee-for-service beneficiaries who had a recent hip fracture.

- Abstract
This is the third annual report describing patients discharged from subacute rehabilitation programs in the United States that subscribe to the Uniform Data System for Medical Rehabilitation (UDSmr). The analysis included 39,562 complete records of first admission cases discharged alive from 180 facilities in 1999. Sixty-five percent of the patients were women, and most patients (91%) were white. Sixty-two percent of the patients were 75 yr of age or older. Before the impairment onset, 55% lived with at least one other person. The average total FIM (motor and cognitive) score change for all patients was 21.1 points, and when stratified by rehabilitation impairment group, average scores ranged from 18.3 for patients with pulmonary conditions to 25.3 for patients with a joint replacement. The percentage of patients discharged to a community-based setting ranged from 67% for patients with stroke to 94% for patients with a joint replacement. These data show that patients receiving care in subacute rehabilitation programs show measurable functional improvement and that a high percentage of patients are discharged to community-based settings.

- Abstract
OBJECTIVES: Length of stay (LOS) and hospital readmission for persons receiving medical rehabilitation were examined. METHODS: A total of 96,473 patient records (1994-1998) were analyzed. Mean age of patients was 68.97 years; 61% were female and 83% were non-Hispanic White. RESULTS: A decrease in LOS of 6.07 days (SD = 3.23) and increase in hospital readmission were found across all impairment groups (P < .001). Readmission increases ranged from 6.7% for amputations to 1.4% for orthopedic conditions. LOS was longer (2.1 days) for readmitted patients (P < .01). Age was not a significant predictor of rehospitalization. CONCLUSIONS: Understanding variables associated with rehospitalization is important as prospective payment systems are introduced for postacute care. [ABSTRACT FROM AUTHOR]

- Abstract
Despite the passage of OBRA'87 for nursing home reform, concerns about care in facilities continue. The Centers for Medicare and Medicaid developed new regulations and the Traditional Survey (TS) process for annual nursing home survey. The survey is conducted by state regional offices to determine facility compliance with federal regulations. Despite the regulations and new survey process, the TS inconsistently identified problems. A computerized process called the Quality Indicator Survey (QIS) was subsequently developed. This study was designed to compare results from TS and QIS on overall deficiencies, select quality indicators, high-severity deficiencies, and severity differences of seven quality indicators in New York State over a 6-year period from 2010 through 2015. Results of t-tests determined a significant difference in the overall mean number of deficiencies (p < .001), and on four indicators: choices (p < .001), nursing staff (p < .001), dental (p < .001), and dignity (p < .05). Facilities using the TS showed a higher mean number of harm level or higher deficiencies (p < .001). Chi-square tests for severity levels showed significantly more higher severity deficiencies on two quality indicators: nutrition (p < 0.001) and hydration (p < 0.05). Thus, the QIS produced a greater mean number of deficiencies, while TS produced more higher severity deficiencies in New York State.

- Abstract
Purpose: This cross-sectional study explores the psychometric properties and dimensionality of the Fullerton Advanced Balance (FAB) Scale, a multi-item balance test for higher-functioning older adults., Methods: Participants (n=480) were community-dwelling adults able to ambulate independently. Data gathering consisted of survey and balance performance assessment. Psychometric properties were assessed using Rasch analysis., Results: Mean age of participants was 76.4 (SD=7.1) years. Mean FAB Scale scores were 24.7/40 (SD=7.5). Analyses for scale dimensionality showed that 9 of the 10 items fit a unidimensional measure of balance. Item 10 (Reactive Postural Control) did not fit the model. The reliability of the scale to separate persons was 0.81 out of 1.00; the reliability of the scale to separate items in terms of their difficulty was 0.99 out of 1.00. Cronbach's alpha for a 10-item model was 0.805. Items of differing difficulties formed a useful ordinal hierarchy for scaling patterns of expected balance ability scoring for a normative population., Conclusion: The FAB Scale appears to be a reliable and valid tool to assess balance function in higher-functioning older adults. The test was found to discriminate among participants of varying balance abilities. Further exploration of concurrent validity of Rasch-generated expected item scoring patterns should be undertaken to determine the test's diagnostic and prescriptive utility.

- Abstract
Objective: To identify demographic, medical, and functional factors associated with transfer of stroke patients to acute hospital services and/or mortality during stroke rehabilitation., Design: Two case-control studies in which logistic regression was used to control for clinical traits associated with differences in likelihood., Setting: A total of 542 US inpatient and rehabilitation units., Participants: A total of 64,471 patients discharged during 1995., Interventions: Not applicable., Main Outcome Measures: Transfer to an acute hospital service and death., Results: There were 5847 (9.1%) acute hospital transfers and 320 (0.5%) deaths. Greater disability at admission was associated with higher odds of both acute hospitalization and mortality. Cardiopulmonary arrest, chest pain, gastrointestinal problems, bleeding disorders, hypercoagulable states, and acute renal difficulties increased the relative odds of acute hospitalization from 3.1 (95% confidence interval [CI], 2.3-4.2) to 12.7 (95% CI, 9.2-17.6). The likelihood of mortality for patients 85 years of age or older was more than 2-fold (2.5; 95% CI, 1.7-3.6) that of patients 65 years of age or younger for blacks, it was nearly 2-fold (1.7; 95% CI, 1.3-2.3) compared with whites, after adjusting for clinical differences., Conclusion: Higher likelihoods of mortality among older patients versus younger, black patients versus white, and patients with more rather than less disability at admission suggest the need for greater vigilance in monitoring medical status.

- Abstract
Context: Rehospitalization following inpatient medical rehabilitation has important health and economic implications for patients who have experienced a stroke., Objective: Compare logistic regression and neural networks in predicting rehospitalization at 3-6-month follow-up for patients with stroke discharged from medical rehabilitation., Design: The study was retrospective using information from a national database representative of medical rehabilitation patients across the US., Setting: Information submitted to the Uniform Data System for Medical Rehabilitation from 1997 and 1998 by 167 hospital and rehabilitation facilities from 40 states was examined., Participants: 9584 patient records were included in the sample. The mean age was 70.74 years (SD = 12.87). The sample included 51.6% females and was 77.6% non-Hispanic White with an average length of stay of 21.47 days (SD = 15.47)., Main Outcome Measures: Hospital readmission from 80 to 180 days following discharge., Results: Statistically significant variables (P <.05) in the logistic model included sphincter control, self-care ability, age, marital status, ethnicity and length of stay. Area under the ROC curves were 0.68 and 0.74 for logistic regression and neural network analysis, respectively. The Hosmer-Lemeshow goodness-of-fit chi-square was 11.32 (df = 8, P = 0.22) for neural network analysis and 16.33 (df = 8, P = 0.11) for logistic regression. Calibration curves indicated a slightly better fit for the neural network model., Conclusion: There was no statistically significant or practical advantage in predicting hospital readmission using neural network analysis in comparison to logistic regression for persons who experienced a stroke and received medical rehabilitation during the period of the study.

- Abstract
Objective: To develop classification models for risk of hospital readmission 80 to 180 days after discharge based the demographic and functional characteristics of persons discharged from acute inpatient rehabilitation after stroke., Design: Retrospective, using information from US facilities subscribing to the Uniform Data System for Medical Rehabilitation (UDS(MR))., Setting: Information submitted to the UDS(MR) from 1994 through 1996 by 167 hospital and rehabilitation facilities from 40 states was examined., Participants: A total of 15,992 records of patients (mean age +/- standard deviation, 70.97 +/- 12.19yr) with a diagnosis of stroke were included in the final sample. The sample included 52.7% women and was 80% non-Hispanic white with an average length of stay (LOS) of 25.31 +/- 14.72 days., Interventions: Not applicable., Main Outcome Measures: Six subscales of the FIM instrument (self-care, sphincter control, transfers, locomotion, communication, social cognition), total FIM, and other predictor variables for regression analysis (gender, age, ethnicity, marital status, prehospital living setting, LOS, primary payer source, level of function-related group)., Results: A logistic regression model included the following statistically significant variables (p <.05): ethnicity, sphincter control, self-care ability, gender, and LOS. The greatest variability occurred among men. Exactly 18.1% of non-Hispanic white men and 17.9% of African-American men were rehospitalized. In contrast, only 10.1% of Hispanic men and 11.4% of Asian men were rehospitalized. The odds of rehospitalization were lowest for Hispanic men., Conclusion: As prospective payment systems are introduced for postacute care, it is important that the relationship among functional abilities, demographic characteristics, and incidence of hospital readmission following medical rehabilitation be examined., (Copyright 2001 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation)

- Abstract
Objective: This study evaluated the validity of the Functional Independence Measure (FIM instrument) in predicting (1) the number of minutes of daily assistance provided, (2) the cost of durable goods currently used, and (3) the number of paid helper hours provided daily to persons with spinal cord injury living in the community., Design: A cross-sectional study., Subjects: One hundred nine persons with spinal cord injury who were a median 6 years postdischarge from initial medical rehabilitation., Results: A significant inverse linear relationship was observed between FIM scores and the square root values of the three cost-related measures. The FIM-18 and the FIM motor scores were the best single predictors of the square root of minutes of assistance (paid and/or unpaid) per day, explaining 85% of variance. The FIM motor measure was the best single predictor of square root of cost of durable goods, explaining 29% of variance. The Self-Care, FIM motor, and FIM-18 scores equally predicted square root of hours of paid help per day, explaining 58% of variance., Conclusion: The findings indicate FIM-related scores predict the amount of assistance needed and certain costs for persons with spinal cord injury disability.

- Abstract
Objective: To determine typical outcome "benchmarks" for 18 functional tasks in patients undergoing stroke rehabilitation. The benchmarks are intended to serve as points of reference to which the outcomes of patients with similar impairments and degrees of disability can be compared., Subjects: Records from 26,339 stroke patients discharged from 252 inpatient facilities across the United States that submitted 1992 data to the Uniform Data System for Medical Rehabilitation., Methods: Stroke impairment was detailed as the presence or absence of hemiparesis resulting from stroke and the side(s) of involvement. Within each of five stroke impairment categories, patients were further classified by the Functional Independence Measure-Function-Related Groups (FIM-FRGs) into nine syndromes by degree of disability (admission motor and cognitive FIM scores) and by age. Outcomes were determined for each stroke syndrome at patients' discharge from medical rehabilitation., Main Outcome Measures: Patients' median performance levels on each of the 18 items making up the FIM, length of stay, and community discharge rates., Results: The majority of patients whose admission motor FIM scores were above 37 were able to eat, groom, dress the upper body, and manage bladder and bowel functions independently by discharge. In addition to these tasks, most of those whose motor FIM scores were above 55 were able to dress the lower body, bathe, and transfer onto a chair/bed or toilet. The majority of patients whose initial motor FIM scores were above 62 points and whose cognitive FIM scores were above 30 gained independence in most tasks, including stair climbing and tub transfers. Community discharge rates ranged from 51.6% for the group of patients with the most severe disabilities to 99.2% for the group with the least severe disabilities., Conclusion: The clinician can apply these benchmarks to guideline development and quality improvement, and in establishing patient goals.

- Abstract
Objective: The purpose of this study was to determine whether the 80 items on the Interest Checklist empirically cluster into the five categories of interests described by Matsutsuyu, the developer of the tool., Method: The Interest Checklist was administered to 367 subjects classified in three subgroups: students, working adults, and retired elderly persons. An 80-item correlation matrix was formed from the responses to the Interest Checklist for each subgroup and then used in a factor analysis model to identify the underlying structure or domains of interest., Results: Results indicated that the Social Recreation theoretical category was empirically independent for all three subgroups; the Physical Sports and Cultural/Educational theoretical categories were empirically independent for only the college students and working adults; and the Manual Skills theoretical category was empirically independent for only the working adults., Conclusion: Although therapists should continue to be cautious in their interpretation of patients' Interest Checklist scores, the tool is useful for identifying patients' interests in order to choose meaningful activities for therapy.

- Abstract
Objective: To present a new version (2.0) of the Functional Independence Measure-Function Related Group (FIM-FRG) case-mix measure., Data Source/study Setting: 85,447 patient discharges from 252 freestanding facilities and hospital units contained in the 1992 Uniform Data System for Medical Rehabilitation., Study Design: Patient impairment category, functional status at admission to rehabilitation, and patient age were used to develop groups that were homogeneous with respect to length of stay. Within each impairment category patients were randomly assigned to one data set to create the system (through recursive partitioning) or a second set for validation. Clinical and statistical criteria were used to increase the percentage of patients classified, expand the impairment categories of FIM-FRGs Version 1.1, and evaluate the incremental predictive ability of coexisting medical diagnoses. Predictive stability over time was evaluated using 1990 discharges., Principal Findings: In Version 2.0, the percentage of patients classified was increased to 92 percent. Version 2.0 includes two new impairment categories and separate groups for patients admitted to rehabilitation for evaluation only. Coexisting medical diagnoses did not improve LOS prediction. The system explains 31.7 percent of the variance in the logarithm of LOS in the 1992 validation sample, and 31.0 percent in 1990 discharges., Conclusions: FIM-FRGs Version 2.0 includes more specific impairment categories, classifies a higher percentage of patient discharges, and appears sufficiently stable over time to form the basis of a payment system for inpatient medical rehabilitation.

- Abstract
A new measure is presented, suitable for documenting severity and response to treatment in chronic low-back pain syndromes. It is self-administered and combines two pain and seven mobility items. These were selected from pre-existing validated instruments on the basis of their sensitivity to change after treatment. Their Italian validated translation was adopted. The measure was administered to 32 chronic low-back pain Italian patients, all refractory to previous conservative treatments. In most cases they presented with herniation or protrusion of 1-3 lumbar discs. Patients were treated with 3-6 sessions of autotraction over a 5- to 15-day period. Scores on the scale were recorded at admission, discharge and follow-up, 1-3 months after treatment. At discharge and at follow-up, patients were asked if, overall, they felt improved, the same or worse. At follow-up, 20 patients out of 32 reported overall improvement. Scalometric properties of the measure were tested using Rasch analysis. For admission and follow-up, items followed a consistent hierarchical relationship along a unidimensional pain/disability variable, which is being called back illness. The items were not redundant, in that they spread well along a wide range of difficulty/severity. The hierarchy matched well with the expected expression of the conditions of the patients. A study was conducted on 34 chronic back pain patients, showing satisfactory test-retest reliability. Depending on the various items, Cohen's unweighted K ranged from 0.27 to 0.78, with ten of the 11 items above the 0.45 level of acceptability, while intraclass correlation coefficients ranged from 0.42 to 0.89. At follow-up, changes in BACKILL of plus 15% or more, with respect to admission, were consistent with patients' reports of improvement in 19 out of 20 cases. Changes in BACKILL of less than 15% were consistent with patients reports of being the same or worse in 11 out of 12 cases.

- Abstract
Objective: The reliability of the Functional Independence Measure (FIMSM) for adults was examined using procedures of meta-analysis., Data Sources: Eleven published studies reporting estimates of reliability for the FIM were located using computer searches of Index Medicus, Psychological Abstracts, the Functional Assessment Information Service, and citation tracking., Study Selection: Studies were identified and coded based on type of reliability (interrater, test-retest, or equivalence), method of data analysis, size of sample, and training or experience of raters., Data Extraction: Information from the articles was coded by two independent raters. Interrater reliability for coding all elements included in the analysis ranged from .89 to 1.00., Data Synthesis: The 11 investigations included a total of 1,568 patients and produced 221 reliability coefficients. The majority of the reliability values (81%) were from interrater reliability studies, and the intraclass correlation coefficient (ICC) was the most commonly used statistical procedure to compute reliability. The reported reliability values were converted to a common correlation metric and aggregated across the 11 studies. The results revealed a median interrater reliability for the total FIM of .95 and median test-retest and equivalence reliability values of .95 and .92, respectively. The median reliability values for the six FIM subscales ranged from .95 for Self-Care to .78 for Social Cognition. For the individual FIM items, median reliability values varied from .90 for Toilet Transfer to .61 for Comprehension. Median and mean reliability coefficients for FIM motor items were generally higher than for items in the cognitive or communication subscales., Conclusions: Based on the 11 studies examined in this review the FIM demonstrated acceptable reliability across a wide variety of settings, raters, and patients.

- Abstract
Objective: To examine the intermodal agreement of Functional Independence Measure (FIM) ratings when obtained by two commonly used approaches: telephone interview and in-person assessment of functional performance., Design: A random sample of 40 persons with hemiparesis was tested by two registered nurses trained in FIM definitions and telephone interview techniques. The two assessments occurred within 5 days of each other. The raters were blind to previous assessments. The administration of assessments was alternated to minimize bias and order effects., Setting: All subjects were assessed at home, between 3 and 10 months after discharge from rehabilitation., Patients: The criteria for inclusion were: (1) diagnosis of cerebral vascular accident (CVA); (2) completion of a minimum of 2 weeks in an acute rehabilitation program; (3) currently living at home; (4) living within a 30-mile radius of the hospital; and (5) cognitive and verbal skills adequate to complete a telephone interview. From a population of 103 patients, 40 subjects were randomly selected, 18 women and 22 men ranging in age from 37 to 90 years., Main Outcome Measures: The intermodal agreement between FIM ratings obtained by telephone interview and in-person assessment was examined using the intraclass correlation (ICC). FIM item scores were analyzed for agreement using the Kappa coefficient. The stability of the responses was determined by computing the coefficient of variation and plotting the data to visually examine the relationship between the two methods of administration., Results: Data analysis revealed that there was no statistically significant difference (p > .05) between the two methods of administration for total FIM score. The total FIM ICC was .97. ICC values for FIM subscales ranged from .85 to .98, except for social cognition. Kappa scores for noncognitive items ranged from .49 (bowel movement) to .93 (grooming). The coefficient of variation computed to examine cognitive and communication items with reduced variability indicated good stability across all items., Conclusion: The results indicated good intermodal agreement for follow-up telephone assessment using the Functional Independence Measure. The findings were limited to persons with effective communication skills.

- Abstract
The Functional Independence Measure (FIM) is an 18-item, 7-level scale developed to uniformly assess severity of patient disability and medical rehabilitation functional outcome. FIM interrater reliability in the clinical setting is reported here. Clinicians from 89 US inpatient comprehensive medical rehabilitation facilities newly subscribing to the uniform Data System for Medical Rehabilitation from January 1988-June 1990 evaluated 1018 patients with the FIM. FIM total, domain and subscale score intraclass correlation coefficients (ICC) were calculated using ANOVA; FIM item score agreement was assessed with unweighted Kappa coefficient. Total FIM ICC was 0.96; motor domain 0.96 and cognitive domain 0.91; subscale score range: 0.89 (social cognition) to 0.94 (self-care). FIM item Kappa range: 0.53 (memory) to 0.66 (stair climbing). A subset of 24 facilities meeting UDSMR data aggregation reliability criteria had Intraclass and Kappa coefficients exceeding those for all facilities. It is concluded that the 7-level FIM is reliable when used by trained/tested inpatient medical rehabilitation clinicians.

- Abstract
Background: To evaluate the efficacy of warm versus cold and antegrade versus retrograde cardioplegia, 163 patients were randomized in sequence in three groups and underwent isolated coronary artery bypasses (mean, 4 grafts/patients) alternating in sequence., Methods and Results: The demographic profiles were identical. Cold crystalloid cardioplegia (group 1) was delivered through the aortic root intermittently. The warm retrograde (group 2) was started antegrade with high potassium solution until the heart stopped. It was continued with retrograde coronary sinus perfusion, 100 mL/min of warm blood. Cold retrograde blood cardioplegia (4:1) (group 3) was started antegrade and continued retrograde through the coronary sinus. The heart temperature was kept at 10 degrees to 15 degrees C. Patients were evaluated intraoperatively and postoperatively for (1) supraventricular tachycardia, (2) ECG changes, (3) lactate dehydrogenase and total CPK and isoenzyme (MB) studies, and (4) hemodynamic studies in the intensive care unit. Warm retrograde and cold retrograde patients had sampling of the ascending aorta (antegrade) and the coronary sinus (retrograde) measuring pH, A-VO2 differences, and CK enzyme leak., Results: The incidence of supraventricular tachycardia was 29% in group 2, 22% in group 1, 18% in group 3; not significant (NS). CPK isoenzyme MB fraction showed identical levels (NS). The warm heart consumed 1.3 to 1.6 mL O2/100 mL flow, while the cold group 3 showed 0.5 to 0.6 mL O2/100 mL flow (P < .001). Cold crystalloid cardioplegia (group 1) was similar to group 3 (0.3 mL O2/100 mL). All three groups were similar hemodynamically (cardiac output, cardiac index, left ventricular stroke work index). Two of 163 patients died in group 2. Four sustained stroke, three in group 2, one with a fatal outcome., Conclusions: Continuous warm cardioplegia (group 2) did not provide better myocardial protection despite that no CK-MB isoenzyme leak was demonstrated intraoperatively. Intermittent cold crystalloid cardioplegia and cold retrograde provided a clearer operative field and motionless heart. As long as O2 was adequately supplied, under 90 minutes' cross-clamp time, cold crystalloid cardioplegia and cold retrograde blood cardioplegia is safe under hypothermic conditions, whereas warm cardioplegia requires continuous uninterrupted technique with oxygen delivery.

- Abstract
The purpose of this study was to investigate disability in persons after stroke by using combinations of functional assessment item, subscale, domain, and full-scale scores, to predict (1) the burden of care measured in minutes of assistance provided per day by another person in the home, and (2) the subject's level of satisfaction with life in general. The Functional Independence Measure (FIM) and the Sickness Impact Profile (SIP) each contributed to prediction of the subject's physical care needs. A change in total FIM score of one point (range, 61 to 126) was equivalent to an average of 2.19 minutes of help from another person per day and a change in one point in the SIP physical dysfunction (SIPPHYS) score (range, 4.0% to 57.4%) was equivalent to an average of 3.32 minutes. Along with the Brief Symptom Inventory and a measure of visual ability, the FIM contributed to predicting the patient's general satisfaction as well. The burden of care and subjective satisfaction with life in general are important standards by which functional assessment instruments may be compared to reflect, in pragmatic terms, the impact of disability on the lives of individuals and on the human and economic resources of the community.

- Abstract
To determine whether previous sternotomy alters internal thoracic artery (ITA) anatomy and flow characteristics, a duplex scanner was used for noninvasive evaluation of the ITA in 59 patients who were scheduled for reoperative coronary artery bypass surgery. The left ITA was insonated through the third intercostal space by use of a duplex scanner (5.0 MHz probe). Measurements of the ITA diameter (mm) and peak systolic velocity (cm/sec) were obtained; ITA flow was calculated from velocity and cross-sectional area. These findings were compared with the values obtained from 105 patients who were scheduled to undergo first-time (primary) coronary artery surgery during the same time period. In the reoperative group, preoperative mean ITA diameter was 2.26 +/- 0.06 mm; this was not significantly different from the primary group's mean ITA diameter of 2.15 +/- 0.04 mm (p = 0.09). Mean peak systolic velocity was 79.9 +/- 2.4 cm/sec and calculated systolic blood flow was 204.6 +/- 13.1 ml/min in the reoperative patients, as compared with 83.3 +/- 2.1 cm/sec and 189.5 +/- 8.6 ml/min in the primary group, respectively. Values were similar in both groups for the peak systolic velocity (p = 0.31) and calculated systolic blood flow (p = 0.32). These results suggest that previous heart surgery or sternotomy does not adversely affect ITA anatomy and flow characteristics. We conclude that ultrasonic imaging is an easily applicable technique for preoperative assessment of ITA in patients who have undergone previous sternotomy.

- Abstract
Background and Purpose: The purpose of this study was to examine the relations between host characteristics (age and side of body affected) and program variables (lengths of stay in acute care and rehabilitation, levels of functional ability at admission and discharge, and rates of community discharge)., Methods: A sample of 7,905 patients was drawn from medical rehabilitation facilities enrolled in the Uniform Data System for Medical Rehabilitation who were admitted and discharged for the first time between January 1988 and June 1989. Data were analyzed using either chi 2 tests or z normal tests of proportions, and analyses of variance (ANOVA) and/or t tests. Significance was set at p less than 0.05, and statistically significant F ratios were examined using Student-Newman-Keuls tests., Results: The average age of patients was 70.7 years (24% less than 65 years, 53% 65-79 years, and 23% greater than 79 years). Lengths of stay in acute care and rehabilitation, admission and discharge functional independence ratings, and rates of community discharge were generally inversely related to patient age. Patients with bilateral paresis had lower rates of community discharge than those with unilateral paresis, although this distinction was not evident in the older group., Conclusions: Results showed that older age and bilateral paresis are negatively associated with levels of independence at admission and discharge and with rates of community discharge.

- Abstract
The internal mammary artery is the preferred conduit for coronary artery surgery. To determine the role, if any, of preoperative duplex imaging in assessing the suitability of this vessel, preoperative noninvasive measurements of internal mammary artery diameter and blood flow were performed in 243 patients. The left internal mammary artery was insonated through the third intercostal space by use of duplex scanner (5.0 MHz probe) before coronary artery surgery. Internal mammary artery diameter (millimeters), peak systolic velocity (centimeters/second), and mean velocity (centimeters/second) were measured, and internal mammary artery flow was calculated from velocity and cross-sectional area. In 45 of these patients the internal mammary artery diameter also was measured during surgery with a sterile caliper, and blood was collected for 30 seconds from the transected internal mammary artery to measure flow. These findings were compared to the preoperative values. In 243 patients the mean internal mammary artery diameter was 2.34 +/- 0.03 mm, and mean peak systolic blood flow was 226.7 +/- 6.3 ml/min. In the 45 patients in whom intraoperative measurements were obtained, preoperative mean internal mammary artery diameter was 2.39 +/- 0.05 mm and was not significantly different from the intraoperative mean internal mammary artery diameter of 2.36 +/- 0.04 mm. Preoperative peak systolic flow was 231.3 +/- 8.1 ml/min, and mean flow was 110.3 +/- 7.1 ml/min; intraoperative flow measured 136 +/- 3.6 ml/min. Noninvasive determinations correlated with operative findings for internal mammary artery diameter (r = 0.87) (p less than 0.05), peak systolic blood flow (r = 0.70) (p less than 0.05), and mean blood flow (r = 0.60) (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

- Abstract
The purpose of this study was to investigate disability in persons with multiple sclerosis (MS) by using combinations of functional assessment scales and subscales to predict (1) the burden of care measured in minutes of assistance provided per day by another person in the home, and (2) the subject's level of satisfaction with life in general. The Functional Independence Measure (FIM), Incapacity Status Scale, Environmental Status Scale, and the Barthel Index had high intercorrelations with each other. Although each was predictive of the MS subject's physical care needs, the FIM was the most useful. A change in total FIM score of one point was equivalent to an average of 3.38 minutes of help from another person per day. With the Brief Symptom Inventory and the Environmental Status Scale, the FIM contributed to predicting the patient's general satisfaction as well. We propose that burden of care and subjective satisfaction with life be the standards by which functional assessment instruments are compared to reflect, in pragmatic terms, the impact of disability on the lives of individuals and on the human and economic resources of the community.

- Abstract
Morbidity and mortality studies of fire fighters have produced varied and inconsistent findings regarding the potential chronic effects of fire fighting including respiratory disease, cardiovascular disease, and cancer. The mortality experience of 1,867 white male fire fighters who were employed for the City of Buffalo a minimum of five years with at least one year as a fire fighter was studied. Vital status was determined for 99% of the cohort, resulting in 470 observed deaths. The fire fighter cohort was characteristic of a healthy worker population. All-cause mortality was close to the expected standardized mortality ratio (SMR) = 95, and significantly lower than expected mortality was seen for all external causes (SMR = 67)--in particular, for suicide (SMR = 21) and respiratory diseases (SMR = 48). Significantly elevated SMRs were found for benign neoplasms (SMR = 417), cancer of the colon (SMR = 183), and cancer of the bladder (SMR = 286). Cause-specific mortality is presented by number of years employed, calendar year of death, year of hire, and latency. Cancer mortality was significantly higher in the long-term fire fighters, and risk of mortality from all malignant neoplasms tended to increase with increasing latency. Patterns in risk of mortality among fire fighters for cancers of the bladder, colon, and brain are intriguing. Additional follow-up of this cohort and initiation of cancer morbidity studies would be helpful in further clarifying the potential long-term effects of fire fighting on cancer risk.

- Abstract
A retrospective cohort mortality study was conducted on 11,499 full-time municipal employees of the City of Buffalo, New York, who were employed at least one day between January 1, 1950 and October 1, 1979 and worked a minimum of five years. This paper outlines the method of the study and presents the all cause and cause-specific mortality for the male cohort of 10,128. Statistically significant deficits in mortality are seen for infectious diseases, diseases of the circulatory system, diseases of the respiratory system, and all external causes. Statistically significant increased mortality is seen for both malignant and benign neoplasms. All cause mortality was significantly lower than expected for professional, manager, and clerical workers. White-collar workers exhibit a decreased risk of mortality from all diseases of the circulatory system, all diseases of the respiratory system, and all external causes of death. No statistically significant increased or decreased risk of mortality from specific cancer sites is seen for white-collar workers. Blue-collar workers show statistically significant deficits in mortality from infectious diseases, all diseases of the circulatory system, all respiratory diseases, and all external causes. Blue-collar workers exhibit statistically significant increases for benign and malignant neoplasms and in particular, malignant neoplasms of the esophagus, large intestine, and rectum. The meaning of these findings will be clarified through analyses of specific worker groups.

- Abstract
The three important sources of bias in retrospective cohort mortality studies are: the healthy worker confounding bias, the lost to follow-up bias, and bias due to methods of follow-up that result in underascertainment of deaths. This paper presents how the treatment of the lost to follow-up impacts ultimately on the apparent forces of mortality in a cohort. The findings are discussed in the context of the other sources of bias. The treatment of subjects lost to follow-up as lost at the time of loss offers the best estimate of expected mortality and should be the preferred approach.

- Abstract
Women have become an increasingly important segment of the total work force, yet there are very few published occupational mortality studies of female workers. This paper reports the findings of a retrospective cohort mortality study of 1,371 full-time female municipal employees of the City of Buffalo, New York, who were employed at least 1 day between January 1, 1950, and October 1, 1979, and who worked a minimum of 5 years. Vital status was ascertained for 88% of the female cohort, resulting in the identification of 214 observed deaths. This predominantly white-collar, service-oriented female cohort demonstrated significantly lower mortality than that expected based on U.S. mortality rates for white females. This strong "healthy-worker effect" was consistent across the time period of the study, across cause-specific mortality especially for all malignant neoplasms and all diseases of the circulatory system, and across different workers groups. Findings are discussed in light of the methodological issues involved in occupational studies of female workers.

- Abstract
Very little is known about the long-term health risks associated with the high stress police officer occupation. We report here on a retrospective cohort of 2,376 ever-employed white male police officers employed between January 1950 and October 1979. Vital status was obtained for 96%, the officers accumulating a total of 39,462 person-years. Six-hundred sixty-one deaths were observed. Total mortality from all causes was comparable to that of the overall U.S. white male population (standardized mortality ratio [SMR] = 106). Significantly increased mortality was seen for all malignant neoplasms combined (SMR = 127), cancer of the esophagus (SMR = 286), and cancer of the colon (SMR = 180). Significantly lower than expected mortality was seen for infectious diseases (SMR = 26), respiratory diseases (SMR = 64), and accidents (SMR = 60). Internal cohort comparisons revealed that policeman exhibited significantly higher mortality from suicide compared to all other municipal employees (rate ratio = 2.9). Analysis of mortality by length of service as a police officer showed that those employed 10-19 years were at significantly increased risk of digestive cancers and cancers of the colon and lymphatic and hematopoietic tissues and decreased risk for all diseases of the circulatory system. Policeman employed more than 40 years had significantly elevated SMRs for all causes, all malignant neoplasms combined, digestive cancers, cancers of the bladder and lymphatic and hematopoietic tissues, and arteriosclerotic heart disease. Risk of mortality from arteriosclerotic heart disease tended to increase with increasing years employed. These findings are discussed in light of the police stress literature. The hypotheses generated in this study must be tested through study of the role of important confounders including reactions to stress on the job.
