Lifting and exertion injuries decrease after implementation of an integrated hospital-wide safe patient handling and mobilisation programme.

OBJECTIVE: With increasing emphasis on early and frequent mobilisation of patients in acute care, safe patient handling and mobilisation practices need to be integrated into these quality initiatives. We completed a programme evaluation of a safe patient handling and mobilisation programme within the context of a hospital-wide patient care improvement initiative that utilised a systems approach and integrated safe patient equipment and practices into patient care plans. METHODS: Baseline and 12-month follow-up surveys of 1832 direct patient care workers assessed work practices and self-reported pain while an integrated employee payroll and injury database provided recordable injury rates collected concurrently at 2 hospitals: the study hospital with the programme and a comparison hospital. RESULTS: Safe and unsafe patient handling practice scales at the study hospital improved significantly (p<0.0001 and p=0.0031, respectively), with no differences observed at the comparison hospital. We observed significant decreases in recordable neck and shoulder (Relative Risk (RR)=0.68, 95% CI 0.46 to 1.00), lifting and exertion (RR=0.73, 95% CI 0.60 to 0.89) and pain and inflammation (RR=0.78, 95% CI 0.62 to 1.00) injury rates at the study hospital. Changes in rates at the comparison hospital were not statistically significant. CONCLUSIONS: Within the context of a patient mobilisation initiative, a safe patient handling and mobilisation programme was associated with improved work practices and a reduction in recordable worker injuries. This study demonstrates the potential impact of utilising a systems approach based on recommended best practices, including integration of these practices into the patient's plan for care.

Impact of Spironolactone on Longitudinal Changes in Health-Related Quality of Life in the Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist Trial.

BACKGROUND: Heart failure (HF) with preserved ejection fraction patients have equally impaired health-related quality of life (HRQL) compared with those with HF with reduced ejection fraction, but limited studies have evaluated the impact of therapies on changes in HRQL. METHODS AND RESULTS: Patients ≥50 years of age, with symptomatic HF and left ventricular ejection fraction ≥45%, were enrolled in Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist (TOPCAT) and randomized to spironolactone or placebo. Patients completed the Kansas City Cardiomyopathy Questionnaire (KCCQ), which was the primary HRQL instrument, and EQ5D visual analog scale at baseline, 4 months, 12 months, and annually thereafter. McMaster Overall Treatment Evaluation was assessed at 4 and 12 months to assess global change scores. Change scores (+SD) were calculated to determine between-group differences, and multivariable repeated-measures models were created to identify other factors associated with change scores. Paired KCCQ data were available for 91.7% of 3445 TOPCAT patients. By 4 months, the mean change in KCCQ was 7.7±16 and mean change in EQ5D visual analog scale was 4.7±16. Adjusted mean changes in KCCQ for the spironolactone group were significantly better than those for the placebo group at 4-month (1.54 better; P=0.002), 12-month (1.35 better; P=0.02), and 36-month (1.86 better; P=0.02) visits. No between-group differences in EQ5D visual analog scale change scores or McMaster Overall Treatment Evaluation were noted. Older age, obesity, current smoking, New York Heart Association class III/IV, and comorbid illnesses were associated with declines in KCCQ scores. Use of spironolactone was an independent predictor of improved KCCQ scores. CONCLUSIONS: In symptomatic HF with preserved ejection fraction patients, use of spironolactone was associated with an improvement in HF-specific HRQL. Several modifiable risk factors were associated with HRQL deterioration. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT00094302.

Implementing an Integrated Health Protection/Health Promotion Intervention in the Hospital Setting: Lessons Learned From the Be Well, Work Well Study.

OBJECTIVE: This study reports findings from a proof-of-concept trial designed to examine the feasibility and estimates the efficacy of the "Be Well, Work Well" workplace intervention. METHODS: The intervention included consultation for nurse managers to implement changes on patient-care units and educational programming for patient-care staff to facilitate improvements in safety and health behaviors. We used a mixed-methods approach to evaluate feasibility and efficacy. RESULTS: Using findings from process tracking and qualitative research, we observed challenges to implementing the intervention due to the physical demands, time constraints, and psychological strains of patient care. Using survey data, we found no significant intervention effects. CONCLUSIONS: Beyond educating individual workers, systemwide initiatives that respond to conditions of work might be needed to transform the workplace culture and broader milieu in support of worker health and safety.

Contemporary results of carotid endarterectomy in "normal-risk" patients from the Society for Vascular Surgery Vascular Registry.

OBJECTIVE: Acceptable complication rates after carotid endarterectomy (CEA) are drawn from decades-old data. The recent Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) demonstrated improved stroke and mortality outcomes after CEA compared with carotid artery stenting, with 30-day periprocedural CEA stroke rates of 3.2% and 1.4% for symptomatic (SX) and asymptomatic (ASX) patients, respectively. It is unclear whether these target rates can be attained in "normal-risk" (NR) patients experienced outside of the trial. This study was done to determine the contemporary results of CEA from a broader selection of NR patients. METHODS: The Society for Vascular Surgery (SVS) Vascular Registry was examined to determine in-hospital and 30-day event rates for NR, SX, and ASX patients undergoing CEA. NR was defined as patients without anatomic or physiologic risk factors as defined by SVS Carotid Practice Guidelines. Raw data and risk-adjusted rates of death, stroke, and myocardial infarction (MI) were compared between the ASX and SX cohorts. RESULTS: There were 3977 patients (1456 SX, 2521 ASX) available for comparison. The SX group consisted of more men (61.7% vs 57.0%; P = .0045) but reflected a lower proportion of white patients (91.3% vs 94.4%; P = .0002), with lower prevalence of coronary artery disease (P < .0001), prior MI (P < .0001), peripheral vascular disease (P = .0017), and hypertension (P = .029), although New York Heart Association grade >3 congestive heart failure was equally present in both groups (P = .30). Baseline stenosis >80% on duplex imaging was less prevalent among SX patients (54.2% vs 67.8%; P < .0001). Perioperative stroke rates were higher for SX patients in the hospital (2.8% vs 0.8%; P < .0001) and at 30 days (3.4% vs 1.0%; P < .0001), which contributed to the higher composite death, stroke, and MI rates in the hospital (3.6% vs 1.8; P = .0003) and at 30 days (4.5% vs 2.2%; P < .0001) observed in SX patients. After risk adjustment, the rate of stroke/death was greater among SX patients in the hospital (odds ratio, 2.05; 95% confidence interval, 1.18-3.58) although not at 30 days (odds ratio, 1.36; 95% confidence interval, 0.85-2.17). No in-hospital or 30-day differences were observed for death or MI by symptom status. CONCLUSIONS: The SVS Vascular Registry results for CEA in NR patients are similar by symptom status to those reported for CREST and may serve as a benchmark for comparing results of alternative therapies for treatment of carotid stenosis in NR patients outside of monitored clinical trials. The contemporary perioperative risk of stroke after CEA in NR patients continues to be higher for SX than for ASX patients.

Baseline distribution of participants with depression and impaired quality of life in the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist Trial.

BACKGROUND: Previous studies have demonstrated the psychosocial effect of heart failure in patients with reduced ejection fraction. However, the effects on patients with preserved ejection fraction have not yet been elucidated. This study aimed to determine the baseline characteristics of participants with heart failure with preserved ejection fraction as it relates to impaired quality of life (QOL) and depression, identify predictors of poor QOL and depression, and determine the correlation between QOL and depression. METHODS AND RESULTS: Among patients enrolled in the Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist Trial (TOPCAT), 3400 patients completed the Kansas City Cardiomyopathy Questionnaire, 3395 patients completed European QOL 5D Visual Analog Scale, and 1431 patients in United States and Canada completed the Patient Health Questionnaire-9. The mean summary score on the Kansas City Cardiomyopathy Questionnaire was 54.8, and on European QOL 5D Visual Analog Scale, it was 60.3; 27% of patients had moderate to severe depression. Factors associated with better Kansas City Cardiomyopathy Questionnaire and European QOL 5D Visual Analog Scale via multiple logistic regression analysis were American region, older age, no history of angina pectoris or asthma, no use of hypoglycemic agent, more activity level, and lower New York Heart Association class. Factors associated with depression via multiple logistic regression analysis included younger age, female sex, comorbid angina, chronic obstructive pulmonary disease, use of a hypoglycemic agent, lower activity level, higher New York Heart Association class, and selective serotonin reuptake inhibitor use. There were significant correlations between each of the QOL scores and depression. CONCLUSIONS: Patients with heart failure with preserved ejection fraction, who were younger had higher New York Heart Association class or comorbid angina pectoris, had lower activity levels, lived in Eastern Europe or were taking hypoglycemic agents, were more likely to have impaired QOL and depression.

The influence of contralateral occlusion on results of carotid interventions from the Society for Vascular Surgery Vascular Registry.

OBJECTIVE: Data on the influence of contralateral carotid occlusion (CCO) on carotid endarterectomy (CEA) are conflicting and are absent for carotid artery stenting (CAS). This study evaluated the influence of CCO on CEA and CAS. METHODS: We evaluated patients with and without CCO in the Society for Vascular Surgery Vascular Registry. Primary outcome was a composite of periprocedural death, stroke, or myocardial infarction (MI) (major adverse cardiovascular events [MACE]) and its individual components. Further analysis was done to identify the influence, if any, of symptom status on outcomes. RESULTS: There were 1128 CAS and 666 CEA patients with CCO. CAS patients were more often symptomatic with a greater incidence of coronary artery disease, congestive heart failure, diabetes, chronic obstructive pulmonary disease, and New York Heart Association class >III. Absolute risk of periprocedural MACE (2.7% for CAS vs. 4.2% for CEA), death (1.1% for CAS vs. 0.7% for CEA), stroke (2.1% for CAS vs. 3.1% for CEA), and MI (0.3% for CAS vs. 0.6% for CEA) was statistically equivalent for both. This equivalence was maintained when patients with CCO were segregated according to symptom status and after adjusting for periprocedural risk. There were 16,646 patients without contralateral occlusion (5698 CAS; 10,948 CEA). Patients without contralateral occlusion with CEA have better outcomes in periprocedural MACE (1.8% for patients without contralateral occlusion vs 4.2% for patients with CCO), and stroke (1.1% for patients without contralateral occlusion vs. 3.1% for patients with CCO) (P < .0001 for both). In CAS patients, CCO did not significantly affect periprocedural MACE (3.2% for patients without contralateral occlusion vs. 2.7% for patients with CCO), death (0.8% for patients without contralateral occlusion vs. 1.0% for patients with CCO), stroke (2.3% for patients without contralateral occlusion vs. 2.1% for patients with CCO), or MI (0.6% for patients without contralateral occlusion vs. 0.3% for patients with CCO). In CEA patients, CCO increased MACE, primarily by increasing stroke rates in asymptomatic (0.7% vs. 2.0%; P = .0095) and symptomatic (1.7% vs. 4.9%; P = .0012) patients. CONCLUSIONS: Although CEA is preferred in patients without contralateral occlusion, regardless of symptom status, based on lower rates of periprocedural MACE, death, and stroke, the benefit of CEA is lost in patients with CCO because of increased stroke rates in CCO patients after CEA but not after CAS regardless of symptom status. The results of CAS and CEA in patients with CCO are equivalent and within acceptable American Heart Association guidelines.

Preoperative symptom type influences the 30-day perioperative outcomes of carotid endarterectomy and carotid stenting in the Society for Vascular Surgery Vascular Registry.

OBJECTIVE: The objective of this study was to determine the effect of presenting symptom types on 30-day periprocedural outcomes of carotid endarterectomy (CEA) and carotid artery stenting (CAS) in contemporary vascular practice. METHODS: Retrospective review was undertaken of the Society for Vascular Surgery Vascular Registry database subjects who underwent CEA or CAS from 2004 to 2011. Patients were grouped by discrete 12-month preprocedural ipsilateral symptom type: stroke, transient ischemic attack (TIA), transient monocular blindness (TMB), or asymptomatic (ASX). Risk-adjusted odds ratios (ORs) were used to compare the likelihood of the 30-day outcomes of death, stroke, and myocardial infarction (MI) and the composite outcomes of death + stroke and death + stroke + MI. RESULTS: Symptom type significantly influences risk-adjusted 30-day outcomes for carotid intervention. Presentation with stroke predicted the poorest outcomes (death + stroke + MI composite: OR, 1.3; 95% confidence interval [CI], 0.83-2.03 vs TIA; OR, 2.56; 95% CI, 1.18-5.57 vs TMB; OR, 2.12; 95% CI, 1.46-3.08 vs ASX), followed by TIA (death + stroke + MI composite: OR, 1.97; 95% CI, 0.91-4.25 vs TMB; OR, 1.63; 95% CI, 1.14-2.33 vs ASX). For both CAS and CEA patients, presentation with stroke or TIA predicted a higher risk of periprocedural stroke than in ASX patients. Presentation with stroke predicted higher 30-day risk of death with CAS but not with CEA. MI rates were not affected by presenting symptom type. The 30-day outcomes for the TMB and ASX patient groups were equivalent in both treatment arms. CONCLUSIONS: Presenting symptom type significantly affects the 30-day outcomes of both CAS and CEA in contemporary vascular surgical practice. Presentation with stroke and TIA predicts higher rates of periprocedural complications, whereas TMB presentation predicts a periprocedural risk profile similar to that of ASX disease.

Work-family conflict, psychological distress, and sleep deficiency among patient care workers.

This study examined whether work-family conflict was associated with sleep deficiencies, both cross-sectionally and longitudinally. In this two-phase study, a workplace health survey was completed by a cohort of patient care workers (n = 1,572). Additional data were collected 2 years later from a subsample of the original respondents (n = 102). Self-reported measures included work-family conflict, workplace factors, and sleep outcomes. The participants were 90% women, with a mean age of 41 ± 11.7 years. At baseline, after adjusting for covariates, higher levels of work-family conflict were significantly associated with sleep deficiency. Higher levels of work-family conflict also predicted sleep insufficiency nearly 2 years later. The first study to determine the predictive association between work-family conflict and sleep deficiency suggests that future sleep interventions should include a specific focus on work-family conflict.

Construction workers working in musculoskeletal pain and engaging in leisure-time physical activity: Findings from a mixed-methods pilot study.

BACKGROUND: While exercise has been shown to be beneficial for some musculoskeletal pain conditions, construction workers who are regularly burdened with musculoskeletal pain may engage less in leisure-time physical activity (LTPA) due to pain. In a small pilot study, we investigate how musculoskeletal pain may influence participation in LTPA among construction workers. METHODS: A sequential explanatory mixed-methods design was employed using a jobsite-based survey (n = 43) among workers at two commercial construction sites and one focus group (n = 5). RESULTS: Over 93% of these construction workers reported engaging in LTPA and 70% reported musculoskeletal pain. Fifty-seven percent of workers who met either moderate or vigorous LTPA guidelines reported lower extremity pain (i.e., ankle, knee) compared with 21% of those who did not engage in either LTPA (P = 0.04). Focus group analyses indicate that workers felt they already get significant physical activity out of their job because they are "moving all the time and not sitting behind a desk." Workers also felt they "have no choice but to work through pain and discomfort [as the worker] needs to do anything to get the job done." CONCLUSION: Pilot study findings suggest that construction workers not only engage in either moderate or vigorous LTPA despite musculoskeletal pain but workers in pain engage in more LTPA than construction workers without pain.

Spironolactone for heart failure with preserved ejection fraction.

BACKGROUND: Mineralocorticoid-receptor antagonists improve the prognosis for patients with heart failure and a reduced left ventricular ejection fraction. We evaluated the effects of spironolactone in patients with heart failure and a preserved left ventricular ejection fraction. METHODS: In this randomized, double-blind trial, we assigned 3445 patients with symptomatic heart failure and a left ventricular ejection fraction of 45% or more to receive either spironolactone (15 to 45 mg daily) or placebo. The primary outcome was a composite of death from cardiovascular causes, aborted cardiac arrest, or hospitalization for the management of heart failure. RESULTS: With a mean follow-up of 3.3 years, the primary outcome occurred in 320 of 1722 patients in the spironolactone group (18.6%) and 351 of 1723 patients in the placebo group (20.4%) (hazard ratio, 0.89; 95% confidence interval [CI], 0.77 to 1.04; P=0.14). Of the components of the primary outcome, only hospitalization for heart failure had a significantly lower incidence in the spironolactone group than in the placebo group (206 patients [12.0%] vs. 245 patients [14.2%]; hazard ratio, 0.83; 95% CI, 0.69 to 0.99, P=0.04). Neither total deaths nor hospitalizations for any reason were significantly reduced by spironolactone. Treatment with spironolactone was associated with increased serum creatinine levels and a doubling of the rate of hyperkalemia (18.7%, vs. 9.1% in the placebo group) but reduced hypokalemia. With frequent monitoring, there were no significant differences in the incidence of serious adverse events, a serum creatinine level of 3.0 mg per deciliter (265 µmol per liter) or higher, or dialysis. CONCLUSIONS: In patients with heart failure and a preserved ejection fraction, treatment with spironolactone did not significantly reduce the incidence of the primary composite outcome of death from cardiovascular causes, aborted cardiac arrest, or hospitalization for the management of heart failure.

Physical activity and body mass index: the contribution of age and workplace characteristics.

BACKGROUND: The workplace is an important domain for adults, and many effective interventions targeting physical activity and weight reduction have been implemented in the workplace. However, the U.S. workforce is aging, and few studies have examined the relationship of BMI, physical activity, and age as they relate to workplace characteristics. PURPOSE: This paper reports on the distribution of physical activity and BMI by age in a population of hospital-based healthcare workers and investigates the relationships among workplace characteristics, physical activity, and BMI. METHODS: Data from a survey of patient care workers in two large academic hospitals in the Boston area were collected in late 2009 and analyzed in early 2013. RESULTS: In multivariate models, workers reporting greater decision latitude (OR=1.02, 95% CI=1.01, 1.03) and job flexibility (OR=1.05, 95% CI=1.01, 1.10) reported greater physical activity. Overweight and obesity increased with age (p<0.01), even after adjusting for workplace characteristics. Sleep deficiency (OR=1.56, 95% CI=1.15, 2.12) and workplace harassment (OR=1.62, 95% CI=1.20, 2.18) were also associated with obesity. CONCLUSIONS: These findings underscore the persistent impact of the work environment for workers of all ages. Based on these results, programs or policies aimed at improving the work environment, especially decision latitude, job flexibility, and workplace harassment should be included in the design of worksite-based health promotion interventions targeting physical activity or obesity.

Gender-specific 30-day outcomes after carotid endarterectomy and carotid artery stenting in the Society for Vascular Surgery Vascular Registry.

OBJECTIVE: Although the optimal treatment of carotid stenosis remains unclear, available data suggest that women have higher risk of adverse events after carotid revascularization. We used data from the Society for Vascular Surgery Vascular Registry to determine the effect of gender on outcomes after carotid endarterectomy (CEA) and carotid artery stenting (CAS). METHODS: There were 9865 patients (40.6% women) who underwent CEA (n = 6492) and CAS (n = 3373). The primary end point was a composite of death, stroke, and myocardial infarction at 30 days. RESULTS: There was no difference in age and ethnicity between genders, but men were more likely to be symptomatic (41.6% vs 38.6%; P < .003). There was a higher prevalence of hypertension and chronic obstructive pulmonary disease in women, whereas men had a higher prevalence of coronary artery disease, history of myocardial infarction, and smoking history. For disease etiology in CAS, restenosis was more common in women (28.7% vs 19.7%; P < .0001), and radiation was higher in men (6.2% vs 2.6%; P < .0001). Comparing by gender, there were no statistically significant differences in the primary end point for CEA (women, 4.07%; men, 4.06%) or CAS (women, 6.69%; men, 6.80%). There remains no difference after stratification by symptomatology and multivariate risk adjustment. CONCLUSIONS: In this large, real-world analysis, women and men demonstrated similar results after CEA or CAS. These data suggest that, contrary to previous reports, women do not have a higher risk of adverse events after carotid revascularization.

Results of a pilot intervention to improve health and safety for health care workers.

OBJECTIVE: To test the feasibility of a multicomponent pilot intervention to improve worker safety and wellness in two Boston hospitals. METHODS: A 3-month intervention was conducted on seven hospital units. Pre- (374 workers) and postsurveys (303 workers) assessed changes in safety/ergonomic behaviors and practices, and social support. Wellness outcomes included self-reported pain/aching in specific body areas (musculoskeletal disorders or MSDs) and physical activity (PA). RESULTS: Pain was reported frequently (81%), and PA averaged 4 hours per week. There was a postintervention increase in safe patient handling (P < 0.0001), safety practices (P = 0.0004), ergonomics (P = 0.009), and supervisor support (P = 0.01), but no changes in MSDs or PA. CONCLUSIONS: Safe patient handling, ergonomics, and safety practices are good targets for worker safety and wellness interventions; longer intervention periods may reduce the risk of MSDs.

Psychosocial stress and multi-site musculoskeletal pain: a cross-sectional survey of patient care workers.

The aim of this study was to assess the relationship between psychosocial factors at work and multi-site musculoskeletal pain among patient care workers. In a survey of 1,572 workers from two hospitals, occupational psychosocial factors and health outcomes of workers with single and multi-site pain were evaluated using items from the Job Content Questionnaire that was designed to measure psychological demands, decision latitude, and social support. An adapted Nordic Questionnaire provided data on the musculoskeletal pain outcome. Covariates included body mass index, age, gender, and occupation. The analyses revealed statistically significant associations between psychosocial demands and multi-site musculoskeletal pain among patient care associates, nurses, and administrative personnel, both men and women. Supervisor support played a significant role for nurses and women. These results remained statistically significant after adjusting for covariates. These results highlight the associations between workplace psychosocial strain and multi-site musculoskeletal pain, setting the stage for future longitudinal explorations.

The impact of Centers for Medicare and Medicaid Services high-risk criteria on outcome after carotid endarterectomy and carotid artery stenting in the SVS Vascular Registry.

OBJECTIVE: The Centers for Medicare and Medicaid Services (CMS) require high-risk (HR) criteria for carotid artery stenting (CAS) reimbursement. The impact of these criteria on outcomes after carotid endarterectomy (CEA) and CAS remains uncertain. Additionally, if these HR criteria are associated with more adverse events after CAS, then existing comparative effectiveness analysis of CEA vs CAS may be biased. We sought to elucidate this using data from the SVS Vascular Registry. METHODS: We analyzed 10,107 patients undergoing CEA (6370) and CAS (3737), stratified by CMS HR criteria. The primary endpoint was composite death, stroke, and myocardial infarction (MI) (major adverse cardiovascular event [MACE]) at 30 days. We compared baseline characteristics and outcomes using univariate and multivariable analyses. RESULTS: CAS patients were more likely to have preoperative stroke (26% vs 21%) or transient ischemic attack (23% vs 19%) than CEA. Although age ≥ 80 years was similar, CAS patients were more likely to have all other HR criteria. For CEA, HR patients had higher MACEs than normal risk in both symptomatic (7.3% vs 4.6%; P < .01) and asymptomatic patients (5% vs 2.2%; P < .0001). For CAS, HR status was not associated with a significant increase in MACE for symptomatic (9.1% vs 6.2%; P = .24) or asymptomatic patients (5.4% vs 4.2%; P = .61). All CAS patients had MACE rates similar to HR CEA. After multivariable risk adjustment, CAS had higher rates than CEA for MACE (odds ratio [OR], 1.2; 95% confidence interval [CI], 1.0-1.5), death (OR, 1.5; 95% CI, 1.0-2.2), and stroke (OR, 1.3; 95% CI,1.0-1.7), whereas there was no difference in MI (OR, 0.8; 95% CI, 0.6-1.3). Among CEA patients, age ≥ 80 (OR, 1.4; 95% CI, 1.02-1.8), congestive heart failure (OR, 1.7; 95% CI, 1.03-2.8), EF <30% (OR, 3.5; 95% CI, 1.6-7.7), angina (OR, 3.9; 95% CI, 1.6-9.9), contralateral occlusion (OR, 3.2; 95% CI, 2.1-4.7), and high anatomic lesion (OR, 2.7; 95% CI, 1.33-5.6) predicted MACE. Among CAS patients, recent MI (OR, 3.2; 95% CI, 1.5-7.0) was predictive, and radiation (OR, 0.6; 95% CI, 0.4-0.8) and restenosis (OR, 0.5; 95% CI, 0.3-0.96) were protective for MACE. CONCLUSIONS: Although CMS HR criteria can successfully discriminate a group of patients at HR for adverse events after CEA, certain CMS HR criteria are more important than others. However, CEA appears safer for the majority of patients with carotid disease. Among patients undergoing CAS, non-HR status may be limited to restenosis and radiation.

Relationship of sleep deficiency to perceived pain and functional limitations in hospital patient care workers.

OBJECTIVE: Health care workers are at high risk of developing musculoskeletal symptoms and pain. This study tested the hypothesis that sleep deficiency is associated with pain, functional limitations, and physical limitations that interfere with work. METHODS: Hospital patient care workers completed a survey (79% response rate) including measures of health, sociodemographic, and workplace factors. Associations of sleep deficiency with pain, work interference due to this pain, and functional limitations were determined. RESULTS: Of 1572 respondents (90% women; mean age, 41 years), 57% reported sleep deficiency, 73% pain in last 3 months, 33% work interference, and 18% functional limitation. Sleep deficiency was associated with higher rates of pain, work interference, and functional limitation controlling for socioeconomic, individual, and workplace characteristics. CONCLUSIONS: Sleep deficiency is significantly associated with pain, functional limitation, and workplace interference, suggesting modifiable outcomes for workplace health and safety interventions.

Society for Vascular Surgery (SVS) Vascular Registry evaluation of comparative effectiveness of carotid revascularization procedures stratified by Medicare age.

OBJECTIVE: Recent randomized controlled trials have shown that age significantly affects the outcome of carotid revascularization procedures. This study used data from the Society for Vascular Surgery Vascular Registry (VR) to report the influence of age on the comparative effectiveness of carotid endarterectomy (CEA) and carotid artery stenting (CAS). METHODS: VR collects provider-reported data on patients using a Web-based database. Patients were stratified by age and symptoms. The primary end point was the composite outcome of death, stroke, or myocardial infarction (MI) at 30 days. RESULTS: As of December 7, 2010, there were 1347 CEA and 861 CAS patients aged < 65 years and 4169 CEA and 2536 CAS patients aged ≥ 65 years. CAS patients in both age groups were more likely to have a disease etiology of radiation or restenosis, be symptomatic, and have more cardiac comorbidities. In patients aged <65 years, the primary end point (5.23% CAS vs 3.56% CEA; P = .065) did not reach statistical significance. Subgroup analyses showed that CAS had a higher combined death/stroke/MI rate (4.44% vs 2.10%; P < .031) in asymptomatic patients but there was no difference in the symptomatic (6.00% vs 5.47%; P = .79) group. In patients aged ≥ 65 years, CEA had lower rates of death (0.91% vs 1.97%; P < .01), stroke (2.52% vs 4.89%; P < .01), and composite death/stroke/MI (4.27% vs 7.14%; P < .01). CEA in patients aged ≥ 65 years was associated with lower rates of the primary end point in symptomatic (5.27% vs 9.52%; P < .01) and asymptomatic (3.31% vs 5.27%; P < .01) subgroups. After risk adjustment, CAS patients aged ≥ 65 years were more likely to reach the primary end point. CONCLUSIONS: Compared with CEA, CAS resulted in inferior 30-day outcomes in symptomatic and asymptomatic patients aged ≥ 65 years. These findings do not support the widespread use of CAS in patients aged ≥ 65 years.

Ergonomic practices within patient care units are associated with musculoskeletal pain and limitations.

BACKGROUND: With the high prevalence of musculoskeletal disorders (MSDs) for patient care unit workers, prevention efforts through ergonomic practices within units may be related to symptoms associated with typical work-related MSDs. METHODS: We completed a cross-sectional survey of patient care workers (n = 1,572) in two large academic hospitals in order to evaluate relationships between self-reported musculoskeletal pain, work interference due to this pain, and limitations during activities of daily living (functional limitations) and with ergonomic practices and other organizational policy and practices metrics within the unit. Bivariate and multiple logistic regression analyses tested the significance of these associations. RESULTS: Prevalence of self-reported musculoskeletal symptoms in the past 3 months was 74% with 53% reporting pain in the low back. 32.8% reported that this pain interfered with their work duties and 17.7% reported functional limitations in the prior week. Decreased ergonomic practices were significantly associated with reporting pain in four body areas (low back, neck/shoulder, arms, and lower extremity) in the previous 3 months, interference with work caused by this pain, symptom severity, and limitations in completing activities of daily living in the past week. Except for low back pain and work interference, these associations remained significant when psychosocial covariates such as psychological demands were included in multiple logistic regressions. CONCLUSIONS: Ergonomic practices appear to be associated with many of the musculoskeletal symptoms denoting their importance for prevention efforts in acute health care settings.

Occupational injuries among nurses and aides in a hospital setting.

BACKGROUND: Patient care workers in acute care hospitals are at high risk of injury. Recent studies have quantified risks and demonstrated a higher risk for aides than for nurses. However, no detailed studies to date have used OSHA injury definitions to allow for better comparability across studies. METHODS: We linked records from human resources and occupational health services databases at two large academic hospitals for nurses (n = 5,991) and aides (n = 1,543) in patient care units. Crude rates, rate ratios, and confidence intervals were calculated for injuries involving no days away and those involving at least 1 day away from work. RESULTS: Aides have substantially higher injury rates per 100 full-time equivalent workers (FTEs) than nurses for both injuries involving days away from work (11.3 vs. 7.2) and those involving no days away (9.9 vs. 5.7). Back injuries were the most common days away (DA) injuries, while sharps injuries were the most common no days away (NDA) injuries. Pediatric/neonatal units and non-inpatient units had the lowest injury rates. Operating rooms and the float pool had high DA injury rates for both occupations, and stepdown units had high rates for nurses. NDA injuries were highest in the operating room for both nurses and aides. CONCLUSIONS: This study supports the importance of a continuing emphasis on preventing back and sharps injuries and reducing risks faced by aides in the hospital setting. Uniform injury definitions and work time measures can help benchmark safety performance and focus prevention efforts.

Society for Vascular Surgery Vascular Registry evaluation of stent cell design on carotid artery stenting outcomes.

OBJECTIVE: The Society for Vascular Surgery (SVS) Vascular Registry (VR) collects data on outcomes of carotid endarterectomy and carotid artery stenting (CAS). The purpose of this study was to evaluate the impact of open vs closed cell stent design on the in-hospital and 30-day outcome of CAS. METHODS: The VR collects provider-reported data on patients using a Web-based database. Data were analyzed both in-hospital and at 30 days postprocedure. The primary outcome is combined death/stroke/myocardial infarction (MI). RESULTS: As of October 14, 2009, there were 4337 CAS with discharge data and 2397 with 30-day data. Open cell stents (OPEN) were used in 3451 patients (79.6%), and closed cell stents (CLOSED) were used in 866 patients (20.4%). Baseline demographics showed no differences in age, gender, race, and ethnicity. However, the OPEN group had more patients with atherosclerosis (74.5% vs 67.4%; P = .0003) as the etiology of carotid artery disease. The OPEN group also had a higher prevalence of preprocedural stroke (25.8% vs 21.4%; P = .0079), chronic obstructive pulmonary disease (COPD; 21.0% vs 17.6%; P = .0277), cardiac arrhythmia (14.7% vs 11.4%; P = .0108), valvular heart disease (7.4% vs 3.7%; P < .0001), peripheral vascular disease (PVD; 40.0% vs 35.3%; P = .0109), and smoking history (59.0% vs 54.1%; P = .0085). There are no statistically significant differences in the in-hospital or 30-day outcomes between the OPEN and CLOSED patients. Further subgroup analyses demonstrated symptomatic patients had a higher event rate than the asymptomatic cohort in both the OPEN and CLOSED groups. Among symptomatic patients, the OPEN patients had a lower (0.43% vs 1.41%; P = .0349) rate of in-hospital mortality with no difference in stroke or transient ischemic attack (TIA). There were no differences in 30-day event rates. In asymptomatic patients, there were also no statistically significant differences between the OPEN and CLOSED groups. After risk adjustment, there remained no statistically significant differences between groups of the primary endpoint (death/stroke/MI) during in-hospital or 30 days. CONCLUSION: In-hospital and 30-day outcomes after CAS were not significantly influenced by stent cell design. Symptomatic patients had higher adverse event rates compared to the asymptomatic cohort. As there is no current evidence of differential outcome between the use of open and closed cell stents, physicians should continue to use approved stent platforms based on criteria other than stent cell design.
