An evaluation of the physical and functional characteristics of resuscitators for use in pediatrics.

OBJECTIVE: To evaluate the physical and functional characteristics of pediatric self-inflating resuscitators. DESIGN: Tested under simulated clinical conditions. Results were analyzed by descriptive analysis. SETTING: A pulmonary laboratory in a university hospital. METHODS: Eight new pediatric self-inflating resuscitators were obtained from the manufacturers and evaluated for functional characteristics including: a) fraction of delivered oxygen at 10 L/min and a tidal volume of 300 mL; b) maximum stroke volume against no resistance; and c) maximum cycling frequency at -5 degrees C, 20 degrees C, and 48 degrees C. The resuscitators were also evaluated for physical characteristics, including potential for misassembly, pressure relief valves, expiratory valve leak, and inspiratory resistance. RESULTS: All resuscitators met the minimum standards of the Canadian Standards Association and American Standards for Testing of Materials. However, one bag cycled at only 32 breaths/min at -5 degrees C, marginally within accepted standards. Only five self-inflating resuscitators had pop-off valves. These valves malfunctioned, with valve activation occurring well above the accepted standards. Three of the self-inflating resuscitators could be misassembled for use. Four of the resuscitators were unable to deliver tidal volumes required for preoxygenation in a 20-kg child. CONCLUSIONS: While these self-inflating resuscitators met the minimum standards, they are all unable to deliver 100% oxygen. One unit is probably not appropriate in the out-of-hospital setting when ambient temperatures are less than 0 degrees C. Those resuscitators that can be misassembled are dangerous in unskilled hands. In addition, reliance on pop-off valve activation to limit airway pressure is dangerous.

Is avoidant coping independent of disease status and stable over time in patients with ankylosing spondylitis?

OBJECTIVE: To determine whether avoidant coping in ankylosing spondylitis (AS) is independent of disease status and whether it is stable over time. METHODS: 658 patients with AS completed a postal questionnaire on health status, including pain and stiffness (BASDAI), physical function (BASFI), and coping (CORS). In CORS, "decreasing activities to cope with pain" and "pacing to cope with limitations" reflect avoidant behavioural coping. Ninety patients continued in a longitudinal study and 70 completed the CORS after four years. The adjusted contribution of age, sex, disease duration, educational level, pain (BASDAI), and physical function (BASFI) to the two avoidant coping strategies at first assessment was determined by multiple linear regression. Agreement between coping at first assessment and four years later was determined by intraclass correlation, and the correlation between change in coping and change in disease status over time by Pearson's correlation. RESULTS: At first assessment, worse physical function (BASFI) and more pain (BASDAI) were associated with "decreasing activities to cope with pain". Worse physical function, but not pain, was associated with "pacing to cope with limitations". The contribution of physical function or pain to the total explained variance in each of the coping strategies was small. Disease duration was not a determinant of avoidant coping, but greater age was associated with "pacing to cope with limitations". Change in avoidant coping strategies over time could not be explained by change in function or pain. CONCLUSIONS: In AS, avoidant coping at a particular time is largely independent of disease duration or status. Variability in avoidant coping over a limited period of four years cannot be explained by change in disease status.

Cumulative failure rate of ileal pouch-anal anastomosis and quality of life after failure.

PURPOSE: The aim of the study was to calculate the cumulative occurrence of pouch failure among 486 patients who had undergone proctocolectomy and ileoanal anastomosis for ulcerative colitis or familial adenomatous polyposis. The other goal was to compare the quality of life in the failure group of 21 patients, the successful group, and the healthy population. METHODS: Data were collected from patient histories, with the probability of pouch failure being calculated by the Kaplan-Meier method. Patients with pouch failure and controls were sent a Short-Form 36-item quality-of-life questionnaire, and data were analyzed with paired -test. RESULTS: The overall failure rate was 5.3 percent (26), including 24 pouch excisions and 2 early deaths (0.4 percent). Cumulative probabilities of pouch failure were 1, 5, and 7 percent at 1, 5, and 10 years, respectively. Neither pouchitis, gender, nor diagnosis correlated with pouch failure, but fistula formation ( p< 0.001) did. Patients with failure had lower quality-of-life scores for physical function (p < 0.02), social function ( p< 0.04), energy ( p< 0.02), and physical role function ( < 0.03) than the healthy population. Scores for physical function ( p< 0.01), energy ( p< 0.01), and physical role function ( p< 0.05) were also lower than those of control patients. CONCLUSIONS: The most common cause of pouch failure is fistula, whereas pouch excision is rarely caused by pouchitis. The impaired quality of life of patients in the failure group was caused by impairment of physical function and restrictions in social life.

Modifiable lifestyle behaviors and functional health in the European Prospective Investigation into Cancer (EPIC)-Norfolk population study.

OBJECTIVE: To examine the association between modifiable lifestyle behaviors and functional health. METHOD: Population-based cross-sectional study in 16,678 men and women aged 40-79 years at baseline in 1993-1997 participating in the European Prospective Investigation into Cancer (EPIC)-Norfolk cohort. RESULTS: Smoking and physical inactivity were associated with poorer physical functional health, equivalent to being 7 years and 10-13 years older, respectively, and poorer mental functional health compared to non-smoking or being physically active. After adjusting for age, body mass index, social class, education, prevalent illness, and other lifestyles; men and women who currently smoke were more likely to report poor physical functional health compared to non-smokers {Odds Ratio (OR)=1.85 (95% confidence interval (CI): 1.49, 2.30) and 1.56 (1.30, 1.87)} and poor mental functional health {1.38 (1.12, 1.70); 1.77 (1.51, 2.07)}, respectively. The OR for good physical function in those who were physically active compared to inactive was 1.67 (1.41, 1.97) in men and 1.63 (1.39, 1.91) in women. Moderate alcohol consumption was positively associated with good physical and mental functional health. CONCLUSION: Modifiable behavioral factors are associated with substantial differences in the observed age-related decline in physical functional health and the prevalence of those in good and poor functional health in the community.

Skeletal muscle mass and muscle strength in relation to lower-extremity performance in older men and women.

OBJECTIVE: Low muscle strength is associated with poorer physical function, but limited empirical evidence is available to prove the relationship between muscle mass and physical function. We tested the hypothesis that persons with lower muscle mass or muscle strength have poorer lower-extremity performance (LEP). DESIGN: A cross-sectional, population-based study. PARTICIPANTS: A cohort of 449 men and women aged 65 years and older living in Amsterdam and its surroundings participating in the second examination (1995-1996) of the Longitudinal Aging Study Amsterdam. MEASUREMENTS: Leg skeletal muscle mass was measured using dual-energy X-ray absorptiometry (DXA). Grip strength was used as an indicator of muscle strength. Timed functional performance tests, including walking and repeated chair stands, were used to assess LEP. RESULTS: After adjustment for body height and age, leg muscle mass was positively associated with LEP in men (regression coefficient 0.178 [95% confidence interval 0.013-0.343], P = .035). In women an inverse association was observed, which became positive after additional adjustment for body mass index (BMI) (0.202 [-0.001-0.405], P = .052). Grip strength was positively associated with LEP in men and women. After additional adjustment for behavioral, physiological, and psychological variables, the associations between leg muscle mass and LEP disappeared, whereas grip strength remained to be independently associated with LEP in men (0.079 [0.042-0.116], P = .0001), with a tendency in women (0.046 [-0.009-0.101], P = .11). Results were similar when quartiles of leg muscle mass or grip strength were used. CONCLUSIONS: These results suggest that low muscle strength, but not low muscle mass, is associated with poor physical function in older men and women. However, prospective studies are needed to investigate the association between loss of muscle mass and physical function.

Patients with depressive symptoms have lower health status benefits after coronary artery bypass surgery.

BACKGROUND: Depression is an established independent prognostic factor for mortality, readmission, and cardiac events after CABG surgery. However, limited data exist on whether depression influences functional outcomes after CABG. METHODS AND RESULTS: We followed 963 patients who underwent first CABG between February 1999 and February 2001. At baseline and at 6 months after CABG, we interviewed patients to assess depressive symptoms using the Geriatric Depression Scale (GDS) and physical function using the Short Form-36 Physical Component Scale (PCS). The patient's physical function was considered improved if the PCS score increased > or =5 points at 6 months. Patients with high GDS scores were younger, were more often female, and had worse physical function and higher comorbidity than patients with low GDS scores. Rates of improvement in physical function were 60.1% for a GDS score <5 (below 75th percentile), 49.8% for a GDS score between 5 and 9 (75th to 90th percentile), and 39.7% for a GDS score > or =10 (> or =90th percentile; P=0.002 for the trend). Depressive symptoms remained a significant independent predictor of lack of functional improvement after adjustment for severity of coronary artery disease, angina class, baseline PCS score, and medical history. A GDS score > or =10 was a stronger inverse risk factor for functional improvement after CABG than such traditional measures of disease severity as previous myocardial infarction, heart failure on admission, history of diabetes, and left ventricular ejection fraction. CONCLUSIONS: Higher levels of depressive symptoms at the time of CABG are a strong risk factor for lack of functional benefits 6 months after CABG.

Long term outcomes from the IMPACT randomised trial for depressed elderly patients in primary care.

OBJECTIVE: To determine the long term effectiveness of collaborative care management for depression in late life. DESIGN: Two arm, randomised, clinical trial; intervention one year and follow-up two years. SETTING: 18 primary care clinics in eight US healthcare organisations. Patients 1801 primary care patients aged 60 and older with major depression, dysthymia, or both. INTERVENTION: Patients were randomly assigned to a 12 month collaborative care intervention (IMPACT) or usual care for depression. Teams including a depression care manager, primary care doctor, and psychiatrist offered education, behavioural activation, antidepressants, a brief, behaviour based psychotherapy (problem solving treatment), and relapse prevention geared to each patient's needs and preferences. MAIN OUTCOME MEASURES: Interviewers, blinded to treatment assignment, conducted interviews in person at baseline and by telephone at each subsequent follow up. They measured depression (SCL-20), overall functional impairment and quality of life (SF-12), physical functioning (PCS-12), depression treatment, and satisfaction with care. RESULTS: IMPACT patients fared significantly (P < 0.05) better than controls regarding continuation of antidepressant treatment, depressive symptoms, remission of depression, physical functioning, quality of life, self efficacy, and satisfaction with care at 18 and 24 months. One year after IMPACT resources were withdrawn, a significant difference in SCL-20 scores (0.23, P < 0.0001) favouring IMPACT patients remained. CONCLUSIONS: Tailored collaborative care actively engages older adults in treatment for depression and delivers substantial and persistent long term benefits. Benefits include less depression, better physical functioning, and an enhanced quality of life. The IMPACT model may show the way to less depression and healthier lives for older adults.

Outcomes of total hip and knee replacement: preoperative functional status predicts outcomes at six months after surgery.

OBJECTIVE: To determine whether patients with knee or hip osteoarthritis (OA) who have worse physical function preoperatively achieve a postoperative status that is similar to that of patients with better preoperative function. METHODS: This study surveyed an observational cohort of 379 consecutive patients with definite OA who were without other inflammatory joint diseases and were undergoing either total hip or knee replacement in a US (Boston) and a Canadian (Montreal) referral center. Questionnaires on health status (the Short Form 36 and Western Ontario and McMaster Universities Osteoarthritis Index) were administered preoperatively and at 3 and 6 months postoperatively. Physical function and pain due to OA were deemed the most significant outcomes to study. RESULTS: Two hundred twenty-two patients returned their questionnaires. Patients in the 2 centers were comparable in age, sex, time to surgery, and proportion of hip/knee surgery. The Boston group had more education, lower comorbidity, and more cemented knee prostheses. Patients undergoing hip or knee replacement in Montreal had lower preoperative physical function and more pain than their Boston counterparts. In patients with lower preoperative physical function, function and pain were not improved postoperatively to the level achieved by those with higher preoperative function. This was most striking in patients undergoing total knee replacement. CONCLUSION: Surgery performed later in the natural history of functional decline due to OA of the knee, and possibly of the hip, results in worse postoperative functional status.

Association between recovery outcomes for work-related low back disorders and personal, family, and work factors.

STUDY DESIGN: Incident cases of work-related low back disorders were identified in an automotive metal stamping plant. Individuals were asked to recall health and work habits at the time of diagnosis of the work-related disorder and to report their current low back pain and physical functioning. OBJECTIVES: To evaluate five measures of health outcomes for work-related low back disorders in an industrial population and to determine potentially modifiable correlates of recovery. SUMMARY OF BACKGROUND DATA: The factors that influence recovery in actively working adults and how to best measure recovery outcome in this population are not well known. METHODS: Eighty-eight hourly employees of a metal stamping plant who experienced a work-related low back disorder were interviewed. Health status, health habits, and family and work relations were assessed with a structured interview to determine their association with various recovery outcomes (low back pain, low back pain disability, physical functioning, general physical health, and lost workdays). Interview information was supplemented with data from the plant's Occupational Safety and Health Administration Form 200 log. RESULTS: The clinical measures of recovery from the work-related low back disorders examined had similar overall predictive ability. However, in multivariate analyses, different potentially modifiable prognostic variables emerged as significant among them. Poorer self-rated health status and high personal stress were correlated with low back pain disability. Higher levels of cigarette smoking were correlated with higher levels of low back pain disability, lower physical functioning, and more severe low back pain at follow-up. CONCLUSION: The choice of measure of recovery from work-related low back disorders should be made in the context of the rehabilitation intervention goal. Interventions designed to modify and promote healthful personal behavior should be given more emphasis in rehabilitation efforts for work-related low back disorders.

Costs of ankylosing spondylitis in three European countries: the patient's perspective.

OBJECTIVE: To assess a patient's out of pocket costs, income loss, time consumption, and quality of life (QoL) due to ankylosing spondylitis (AS) in three European countries and to assess variables predicting these outcomes. METHODS: 216 patients with AS from the Netherlands, France, and Belgium participated in a two year study. Health resource use, days absent from work, time lost, and quality of life (EuroQol) were assessed by bimonthly questionnaires. AS related healthcare and non-healthcare expenditure and income loss were calculated taking into account country-specific regulations. Predictors of costs, time consumption, and QoL were analysed by Cox's regression. RESULTS: 209 patients provided data for cost analysis. Average annual healthcare and non-healthcare expenditure was euro;431 per patient and average annual income loss was euro;1371 per patient. Healthcare costs were highest for Belgian and lowest for French patients, while non-healthcare costs were highest for Dutch patients. A patient's total costs were associated with higher age and worse physical function. On average, patients with AS needed 75 minutes additional time a day because of AS. Worse physical function and higher disease activity predicted time consumption. After adjusting for baseline confounders, QoL was worse in Belgian and French than in Dutch patients. Peripheral arthritis, worse physical function, higher disease activity, and loss of income contributed to worse QoL. CONCLUSION: AS is time consuming and associated with substantial out of pocket costs. Belgian patients incur the highest healthcare payments. Poor physical function increases patient's costs and time consumption. Loss of income is associated with lower QoL.

The impact of spinal problems on the health status of patients: have we underestimated the effect?

STUDY DESIGN: A prospective study of 17,774 patients who consulted spine centers in which the impact of spinal disorders and comorbidities on physical functional status were evaluated. OBJECTIVES: To quantify the effect spinal diagnoses have on patients' physical functional status (SF-36 Physical Component Summary [PCS] score) compared with other common conditions and to quantify the effects of comorbidities on physical functional status in spine patients. SUMMARY OF BACKGROUND DATA: The burden of spinal conditions on a patient's function and the role that comorbidities play in this affliction are poorly quantified in the literature. METHODS: Data from the Health Survey Questionnaire were prospectively gathered through the National Spine Network, a nonprofit consortium of spine-focused practices. Each patient's SF-36 score was summarized into a single PCS score. The correlation between diagnosis and comorbidity and PCS score was assessed using multivariate linear regression. RESULTS: The study patients were a mean of 47.5 years of age, 54.7% were female, 52.3% had lumbosacral diagnoses, and 82.0% had had 3 or more months of pain. The population had a mean PCS score of 30.4 +/- 9.95 (SD) compared with 50.0 +/- 10.00 for the general United States population. The more comorbidities in a patient, the lower the PCS score (Spearman rank correlation = -0.27). The five comorbid conditions that lowered the PCS the most included congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), renal failure, rheumatoid arthritis, and lupus (all P <0.001). In multiple linear regression analysis, age, gender, diagnosis, and comorbidity explained 12.1% of the variance in PCS score. CONCLUSIONS: The PCS score is greatly affected in patients with spinal problems. The study population's PCS (30.4) was lower or similar to the PCS for patients with other illnesses reported in the literature: CHF (31.0), COPD (33.9), SLE (37.1), cancer (38.4), primary total hip arthroplasty (29.0), primary total knee arthroplasty (32.6), and glenohumeral degenerative joint disease (35.2). Further, the presence of comorbidity in spine patients adds to the burden of spinal conditions on functional status.

Get up and go test in patients with knee osteoarthritis.

OBJECTIVE: To determine the reliability, minimum detectable change (MDC), and validity of the Get Up and Go (GUG) test. DESIGN: Repeated-measures test-retest for reliability. Correlational study for validity. SETTING: Institutional practice. PARTICIPANTS: Convenience sample of 130 people, 105 with knee osteoarthritis (OA) (80 women; mean age, 62+/-9 y) and 25 healthy controls (21 women; mean age, 57+/-8 y). INTERVENTIONS: Not applicable. Main outcome measures Western Ontario and McMaster Universities Osteoarthritis Index, the Activity of Daily Living Scale of the Knee Outcome Survey, and the 8 scales of the Medical Outcomes Study 36-Item Short-Form Health Survey. RESULTS: Intratester and intertester reliability was.95 (95% confidence interval [CI],.72-.98) and.98 (95% CI,.94-.99), respectively. The MDC, based on measurements by a single tester and between testers, was 1.5 and 1.2 seconds, respectively. Time to perform the GUG test was longer for persons with knee OA than it was for the controls (mean difference, 3.3s; 95% CI, 1.8-4.9). Correlations between the GUG test and measures of physical function did not differ significantly from correlations between the GUG test and measures that do not specifically evaluate physical function. CONCLUSIONS: The GUG test is reliable and has an MDC that is adequate for clinical use. Validity of the GUG test as a single measure of physical function was not supported. Further research should include testing a battery of performance-based measures of physical function.

Patient-based outcomes for the operative treatment of degenerative lumbar spinal stenosis.

STUDY DESIGN: A retrospective surgical case series was conducted using a condition-specific, patient-based outcomes assessment. OBJECTIVE: The goal of this study was to describe the outcome predictors of decompressive surgery for degenerative lumbar spinal stenosis (DLSS). SUMMARY OF BACKGROUND DATA: Surgical decompression is the recommended treatment for patients with moderate to severe DLSS. Previous studies have reported that factors such as the number of operated levels and patient health status are predictors of surgical outcomes. METHODS: This study analyzed the success rates of 58 DLSS patients treated with decompressive surgery. Outcomes were measured with the Zurich Claudication Questionnaire (ZCQ) completed pre-operatively and at least 12 months post-operatively (range 12-54 months). The ZCQ includes three distinct domains that involve symptom severity, physical function, and patient satisfaction. Variables such as age, sex, pre-operative symptom severity, and arthrodesis were analyzed as predictors of success. RESULTS: The study group included 21 males and 37 females, and the mean age of all patients was 66 years (range 41-80 years). Overall, 63.8% of the patients had significant clinical improvement in Symptom Severity, 55.2% had significant clinical improvement in Physical Function, and 58.6% of the patients were at least somewhat satisfied; 63.8% (37/58) of the patients were considered to be clinically successful. Patients with more severe pre-operative symptoms and more physical function restrictions had better success results than those patients with milder symptoms and less restrictive physical function. Also, patients who were followed for less than 24 months had better success than those followed for more than 24 months. There was no significant difference in the clinical success rates of (1) patients who were fused and those not fused, (2) males and females, (3) patients aged less than 65 years and those greater than 65 years, and (4) patients who were treated at one or two levels and those treated at three or four levels. CONCLUSION: The results of this retrospective study indicate that operative decompression of the lumbar spine offers significant improvement for patients with DLSS. Although not all comparisons were statistically significant, there was a trend for DLLS patients aged less than 65 years with more severe pre-operative symptoms and physical function disturbances treated at one or two levels with a laminectomy and fusion to have the best outcomes.

Influence of age on dynamic position sense: evidence using a sequential movement task.

Age related changes to the nervous system are well documented. The main objectives of this study were to examine age-associated changes in dynamic position sense and relate these changes to measures of balance and physical function. Two groups of individuals (young <30 years; elderly >60 years) performed an upper extremity movement sequence triggered by a pre-determined target angle during passive rotations of the ankle joint at ten random velocities (10-90 degrees s(-1)). Balance was assessed with a series of timed standing tests. Physical function was assessed with the SF 36 questionnaire. Muscle activity was recorded from the ankle dorsiflexors and plantarflexors during the dynamic position tests. Increased error in the elderly group suggested that dynamic position sense declines with age. Moreover, this decline in dynamic position sense was associated with decreased balance and an impaired perception of physical function. The elderly also co-contracted the ankle plantarflexors and dorsiflexors during the proprioceptive testing, perhaps as a strategy to "gain up" spindle sensitivity. These findings suggest that impaired dynamic position sense of the ankle contributes to alterations in the overall physical function and balance in the elderly. Rehabilitative training methods that improve dynamic position sense of the ankles may improve physical function and balance in the elderly.

Socioeconomic factors, perceived control and self-reported health in Russia. A cross-sectional survey.

Russia has the lowest life expectancy among industrialised countries, but little is known about other health outcomes and determinants of health in the Russian population. Here we report a cross-sectional study in a national sample of the Russian population of social and psychosocial determinants of two self-reported health indicators: self-rated health (shown to predict mortality in prospective studies) and physical functioning (validated against more objective health measures). A multi-stage sample of the Russian population aged 18 years and more was interviewed (n=1599, response rate 66%). The questionnaire included political attitudes, social and economic circumstances, psychosocial factors, smoking, alcohol consumption, self-rated health and physical functioning (from the SF36 instrument). Scores of perceived control over life and over one's health were calculated from 6 and 3 questions, respectively. Data were analysed in logistic regression for two dichotomised outcomes: poor self-rated health (worse than average) and low physical functioning (less than 60% of maximum). Overall, 25% of subjects rated their health as worse than average; this is substantially more than in western countries. Perceived control over life was strongly related to both outcomes; age- and sex-adjusted OR for 1 standard deviation increase in control were 0.60 (95% CI 0.52-0.69) for poor self-rated health and 0.67 (0.57-0.81) for low physical functioning. Adjustment for a battery of other factors reduced these estimates only slightly. Associations between control over one's health and both outcomes were also significant, but weaker and attenuated in multivariate models. Material deprivation was also strongly related to both outcomes. Education was inversely related to self-rated health, and unmarried men reported poor physical functioning substantially more often. Subjects not approving the economic changes reported poorer health but this association was removed by adjustment for socioeconomic factors and control. Subjects who could not rely on informal social structures when in problems reported worse health; this effect largely persisted in multivariate analyses. These results are consistent with the hypothesis that poor health status in Russia is related to dysfunction of social structures, socioeconomic deprivation, and lack of perceived control. The absence of informal social networks, vital for maintaining general welfare, seems to affect adversely self-rated health. Deprivation and low perceived control may be important mediators between the broad social environment and health in populations undergoing transition and can provide a useful framework for many biological and behavioural factors. Prospective studies are needed to address the issue of temporality and reporting bias, the major problems in interpreting these findings.

A self-report Thompson articular index: what does it measure?

The aim of this study was to investigate the reliability and validity of the self-report Thompson articular index (ThAI) in Dutch patients with rheumatoid arthritis (RA). A rheumatologist assessed the ThAI in 43 patients with RA. Patients completed the self-report ThAI and the AIMS-2 questionnaire to assess physical function, pain, mood and level of tension. Blood samples were taken to measure the erythrocyte sedimentation rate (ESR). After 4 weeks, patients were sent a questionnaire for a repeat assessment of the self-report AI. The test-retest reliability of the self-report ThAI was adequate (ICC=0.83). There was low agreement between ThAI scores from patients and AI scores assessed by the rheumatologist (ICC=0.44). Self-report ThAI scores (mean=230.5) were significantly higher than the rheumatologist's scores (mean=110.8). Levels of agreement between patients and rheumatologist for individual joints were disappointing, ranging from 49% to 74% (Cohen's kappa from -0.02 to 0.48). The rheumatologist's ThAI scores correlated significantly with ESR (r=0.55) and physical function (r=0.44), but not with pain, mood or level of tension. Patients' scores correlated significantly with physical function (r=0.51), pain (r=0.43), and mood (r=0.36) but not with ESR or level of tension. In regression analyses the only significant predictor of the rheumatologist's ThAI scores was ESR, and for patients' scores physical function, thus showing that patients' responses are not confounded by mood or level of tension. In conclusion, the self-report ThAI is a reliable measure, but the validity is questionable because of the non-significant correlation with ESR and the low level of agreement between patients and rheumatologist. The results indicate that self-reported joint involvement is more closely related to physical function than to arthritic activity.

Assessment of decline in health-related quality of life among angina-free patients undergoing coronary artery bypass graft surgery.

PURPOSE: Coronary artery bypass graft (CABG) surgery generally decreases symptoms and improves quality of life, but for those patients without angina, prolongation of life takes precedence. We used the SF-36 to assess changes in health-related quality of life (HRQOL) among patients who were angina free prior to CABG compared to those reporting angina. METHODS: We combined data from two randomized trials of hemodynamic management during surgery. Prior to CABG, demographic, clinical and SF-36 data were obtained. Patients were reevaluated at a 6-month follow-up. Patients with a decline of > or =15 points from baseline to follow-up for individual SF-36 domains and >5 points for summary components were classified as having a decline. We used logistic regression models that controlled for baseline SF-36 score and other baseline characteristics to assess HRQOL decline with respect to angina status. RESULTS: Of 590 patients, 28% were angina free at baseline. A third of the patients angina free at baseline had a postoperative decline in physical function. Patients who were angina free at baseline were three times more likely to suffer a decline in physical function than those with angina (odds ratio 3.29, 95% confidence interval 1.86-5.82). This finding remained after addition of adverse outcomes to the model. Baseline angina status was not related to any other SF-36 domain or to physical or mental summary component scores. Major adverse outcomes did not differ between angina-free patients and those with angina. CONCLUSIONS: The incidence of patients reporting a decline in physical function after CABG was greater in patients without angina preoperatively, even when adjusting for baseline score. Given the substantial risk of decreased physical functioning, employing interventions to maintain HRQOL in this population should be considered.

[Physical quality of life and social support in patients on the waiting list and after a lung transplantation].

BACKGROUND: The present study was carried out to assess quality of life, level of depression and perceived social support of patients on the waiting list and after a lung transplantation. METHODS: 19 patients on the waiting list for lung transplantation and 20 patients 5 - 47 months after transplantation were enrolled in the study. Quality of life was measured by the SF-36 Health Survey, the level of depression with Beck Depression Inventory (BDI) and the perceived social support with the questionnaire for social support (F-SOZU). RESULTS: Significant differences were observed in indicators regarding physical functioning, role-physical, vitality, health perception and social functioning. Both groups showed equal levels of depression and their number of perceived support persons. The perceived support correlates negatively with the level of depression. Transplanted women reported significant more burdensome relationships when compared to transplanted men. CONCLUSION: The effects of lung transplantation are shown best in all indexes of SF-36 associated with physical functioning. In both groups social support is positively correlated with the quality of life and negatively correlated with the level of depression. Perceived positive relationships reduces the risk of psychological disturbance. However, the results may also point to a different coping pattern for patients with a low level of depression.
