Evaluating Systemized Nomenclature of Medicine Clinical Terms Coverage of Complementary and Integrative Health Therapy Approaches Used Within Integrative Nursing, Health, and Medicine.

The use of complementary and integrative health therapy strategies for a wide variety of health conditions is increasing and is rapidly becoming mainstream. However, little is known about how or if complementary and integrative health therapies are represented in the EHR. Standardized terminologies provide an organizing structure for health information that enable EHR representation and support shareable and comparable data; which may contribute to increased understanding of which therapies are being used for whom and for what purposes. Use of standardized terminologies is recommended for interoperable clinical data to support sharable, comparable data to enable the use of complementary and integrative health therapies and to enable research on outcomes. In this study, complementary and integrative health therapy terms were extracted from multiple sources and organized using the National Center for Complementary and Integrative Health and former National Center for Complementary and Alternative Medicine classification structures. A total of 1209 complementary and integrative health therapy terms were extracted. After removing duplicates, the final term list was generated via expert consensus. The final list included 578 terms, and these terms were mapped to Systemized Nomenclature of Medicine Clinical Terms. Of the 578, approximately half (48.1%) were found within Systemized Nomenclature of Medicine Clinical Terms. Levels of specificity of terms differed between National Center for Complementary and Integrative Health and National Center for Complementary and Alternative Medicine classification structures and Systemized Nomenclature of Medicine Clinical Terms. Future studies should focus on the terms not mapped to Systemized Nomenclature of Medicine Clinical Terms (51.9%), to formally submit terms for inclusion in Systemized Nomenclature of Medicine Clinical Terms, toward leveraging the data generated by use of these terms to determine associations among treatments and outcomes.

Factors predicting episodic memory changes in older adults with subjective cognitive decline: A longitudinal observational study.

Episodic memory is affected early in the neuropathological process of Alzheimer's dementia. This study was performed to identify longitudinal associations between baseline vascular/neuropsychiatric risk factors and episodic memory changes over 4.1 ± 2.4 years in 1,401 older adults with subjective cognitive decline (age 74.0 ± 8.2 years). Data were from the National Alzheimer's Coordinating Center-Uniform Data Set and linear mixed effects regression models were used. Reference was those without risk factors. Participants with hypercholesterolemia and with former cigarette smoking had higher episodic memory scores, but current smokers had fewer points than reference at their first and follow-up visits. Despite no difference at baseline, episodic memory scores decreased in those with depressive symptoms relative to reference over time. In older adults with subjective cognitive decline, interventions managing current smoking and depressive symptoms could preserve episodic memory, which may result in delaying the onset of Alzheimer's dementia. Further research is required for the role of cholesterol and smoking.

Influence of Changes in Sedentary Time on Outcomes of Supervised Exercise Therapy in Individuals with Comorbid Peripheral Artery Disease and Type 2 Diabetes.

BACKGROUND: Although supervised exercise therapy (SET) is effective in improving walking distance among adults with symptomatic peripheral artery disease (PAD), some research suggests that individuals with comorbid PAD and type 2 diabetes mellitus (T2DM) may experience a blunted response to SET. It is unknown whether free-living sedentary time changes during SET, and if increases in sedentary time could, in part, explain poor response to SET. The purposes of this pilot study were to (1) determine if older adults with PAD (with and without T2DM) engaging in SET change their sedentary behavior and (2) examine the relationship between changes in sedentary behavior and SET outcomes. We hypothesized that decreased sedentary time during SET would be associated with greater improvements in six-minute walk test (6MWT) total distance and other key SET outcomes. METHODS: Participants (n = 44) initiating a 12-week SET program completed the 6MWT, Short Physical Performance Battery, Walking Impairment Questionnaire, and accelerometer-assessed sedentary behavior at SET initiation, 6 weeks, and 12 weeks. RESULTS: Participants' mean age was 72.3 (7.1) years, mean ankle-brachial index was 0.71 (0.25), and 47.7% were female. On average, sedentary time did not change after SET, although there was substantial variability (-40% to +38% change in minutes of sedentary time/day). Participants with T2DM experienced greater improvements in claudication onset distance than participants without T2DM (mean = 35 m, P = 0.044, 95% confidence interval = 1.6 to 115.4 m). Neither changes in sedentary time from baseline to 6 weeks (P = 0.419) nor T2DM (P = 0.154) predicted changes in 6MWT total distance from baseline to 12 weeks. CONCLUSIONS: As SET availability increases, further examination of factors that may influence SET outcomes will help maximize benefits of this proven therapy.

Power of Peer Support to Change Health Behavior to Reduce Risks for Heart Disease and Stroke for African American Men in a Faith-Based Community.

INTRODUCTION: Peer support has powerful potential to improve outcomes in a program of health behavior change; yet, how peer support is perceived by participants, its role, and how it contributes to intervention efficacy is not known, especially among African Americans. The purpose of this study was to identify the subjectively perceived experience and potential contributions of peer support to the outcomes of a peer group behavioral intervention designed to change health behavior to reduce risks for heart disease and stroke in African American men in a faith-based community. METHODS: A peer support group intervention was implemented to increase health knowledge and to improve health behaviors in line with the American Heart Association's Life Simple 7 domains (get active, control cholesterol, eat better, manage blood pressure, lose weight, reduce blood sugar, and stop smoking). Fourteen peer group sessions and eight follow-up interviews with program participants were recorded, transcribed, and analyzed. RESULTS: Seven key themes emerged, including (1) enhancing access to health behavior information and resources, (2) practicing and applying problem-solving skills with group feedback and support, (3) discussing health behavior challenges and barriers, (4) sharing health behavior changes, (5) sharing perceived health outcome improvements and benefits, (6) feelings of belonging and being cared for, and (7) addressing health of family and community. CONCLUSION: Qualitative findings revealed a positive perception of peer support and greater understanding of potential reasons why it may be an effective strategy for African American men.

The Relationship Between Peripheral Artery Disease Symptomatology and Ischemia.

BACKGROUND: Fewer than half of individuals with peripheral artery disease (PAD) experience classic claudication, and the relationships between PAD typical or atypical symptom intensity, location, and description (classic or atypical) with ischemic changes have not previously been reported. OBJECTIVE: The primary purpose of this study was to evaluate the relationship between self-reported PAD symptom intensity and calf tissue ischemia measured using the tissue saturation index (TSI) during treadmill exercise. The location and descriptors of atypical PAD symptoms in the presence of calf tissue ischemia were also identified. METHODS: Adults with PAD with exercise-limiting ischemic symptoms were asked to (a) rate symptom intensity using a numerical rating scale (NRS) from 0 to 5 (0 = no pain, 1 = onset of pain, 5 = maximal pain), (b) provide symptom locations and descriptors, and (c) wear a near-infrared spectroscopy device to obtain calf TSI values during treadmill exercise. Multilevel models with TSI as the outcome variable were estimated during exercise and recovery. Covariates included were exercise time, recovery time, baseline TSI, exercise rating, recovery rating, ankle-brachial index (ABI), age, race, gender, body mass index, diabetes, neuropathy, and smoking. RESULTS: During three successive bouts of treadmill exercise for 40 participants (80% Caucasian men; average age = 68 years, SD = 9.2), the most rapid decline in TSI occurred between the start of exercise and symptom onset (when NRS = 1). The TSI nadir was often reached prior to report of maximum discomfort (when NRS = 5), and changes in TSI were related to exercise time (p < .001), baseline TSI (p < .001), exercise ratings (p < .001), and ABI (p < .05). During recovery, TSI increased steadily for most participants as pain eased. In the recovery model, changes in TSI were associated with recovery ratings (p < .001) and ABI (p < .03). Of 120 treadmill exercise tests, 69.2% were stopped due to discomfort in the calf with classic descriptors reported only half the time (55.4%). DISCUSSION: Exploratory analyses revealed ischemic symptoms extended beyond classic claudication locations and descriptors. Future research should evaluate changes in TSI relative to atypical locations and descriptors to improve understanding of the full range of ischemic symptoms experienced by individuals with PAD.

Preventing cardiovascular disease in women: how can we do better?

PURPOSE OF REVIEW: This review highlights advances in the primary and secondary prevention of cardiovascular disease (CVD) in women in the preceding 12 months. RECENT FINDINGS: The American Heart Association (AHA) has recently published guidelines on the prevention of CVD in women, which brought new attention to this important topic. Limited progress has been made regarding an awareness of CVD among women, and modest progress has been made on the creation of health behavior change programs that effectively reduce smoking, increase physical activity and improve nutrition. Preventive therapies have been demonstrated to improve outcomes in women with diagnosed disease, but more research that includes women is required to further assess the benefits of primary preventive strategies and therapies. SUMMARY: A review of the literature from the past year confirms the recommendations and direction set in the AHA's updated prevention guidelines. This review illuminates promising new directions for practice and the need for future research focused on strategies to advance early and lasting lifestyle changes to promote cardiovascular health and the prevention of CVD. Adoption of and adherence to the guidelines, continued evaluation and publication of effective practice strategies, and ongoing research are critical to improve efforts to prevent CVD in women.

Challenges of implementing a feasibility study of acupuncture in acute and critical care settings.

A majority of people in the United States use complementary and alternative therapies, and this use is increasing. With the increasing interest, providers must evaluate potential risks and benefits of these therapies. This article describes challenges of a feasibility study of acupuncture as a potential therapeutic adjunct to prevent atrial fibrillation following coronary artery bypass graft surgery. Institutional review board approval, consent logistics, implementation issues, and rapid changes in clinical practice were the primary challenges faced. Unique technological features of the institution helped address these challenges. The study protocol was acceptable to staff, patients, and family and was considered safe for these patients. However, the protocol was not feasible as designed; therefore, the efficacy of acupuncture could not be determined. Continued research is needed to evaluate the effectiveness of acupuncture to prevent atrial fibrillation following coronary artery bypass graft surgery. Recommendations for future studies of complementary and alternative therapies in acute and critical care settings are offered.

Health-related quality of life and subjective neurocognitive function three months after coronary artery bypass graft surgery.

PURPOSE: We compared health-related quality of life (HRQL), including patient-perceived neurocognitive function at preoperative baseline and 3 months after coronary artery bypass (CABG) surgery. DESIGN: The design was prospective and comparative. SETTING: The study took place in the cardiovascular units at two large metropolitan Midwestern hospitals. SAMPLE: The study included a consecutive convenience sample of 64 patients who underwent CABG. METHODS: Preoperative baseline and mailed survey at 3 months post-CABG included the Short-Form 12 (subjective health-status), State Trait Anxiety Inventory (state anxiety), Center for Epidemiological Studies of Depression (depressive symptoms), and Cantril Ladder of Life Satisfaction (global life satisfaction). Investigator-developed questions assessed satisfaction in life domains, cardiac symptoms, and frequency of symptoms related to neurocognitive function. RESULTS: Significant improvements were demonstrated 3 months postoperatively, including the Physical Component Summary, Mental Component Summary, depression, anxiety, satisfaction with social and mental life domains, and patient-perceived neurocognitive function related to memory and concentration. CONCLUSIONS: Patients reported improvements in HRQL measures, including two of three subjective neurocognitive measures. Health care providers facilitate preparation for the CABG recovery trajectory by discussing expected post-hospital experience and potential postoperative variations in emotions and neurocognitive function.

Exercise, quality of life, and symptoms in men and women five to six years after coronary artery bypass graft surgery.

BACKGROUND: Coronary artery bypass graft (CABG) surgery is commonly performed to treat symptoms of heart disease and improve function and quality of life (QL). Health-related behavior including exercise after surgery may promote optimal recovery; however, relationships among exercise behavior, functional status, symptoms, and QL 5 to 6 years after CABG have not been examined in a representative patient sample. METHODS: Telephone interviews and postal surveys were used to examine long-term (5-6 year) recovery after CABG of 163 men and women of the Minnesota participants enrolled in the Post-CABG Biobehavioral Study. RESULTS: Regular exercise and better functional status were related to reports of less shortness of breath and fatigue and better subjective health perception, satisfaction, and QL. RECOMMENDATIONS: Positive relationships between regular exercise and more favorable QL and symptom relief 5 to 6 years after CABG in this observational cohort study warrant prospective study trials to determine the potential long-term benefits of regular exercise after CABG.

Caregiver burden and outcomes of caregiving of spouses of patients who undergo coronary artery bypass graft surgery.

BACKGROUND: Patients who undergo coronary artery bypass graft surgery often rely on spouses for care during recovery. Although often meaningful, caregiving may be stressful and affect spouses' ability to provide care to the patient. OBJECTIVES: The purpose of this study was to compare burden and caregiving outcomes across three groups of spouses. Spouse groups varied by the interval of time between surgery and follow-up, which may have been 3, 6, or 12 months. METHODS: This cross-sectional comparative study recruited a convenience sample of 166 spouses on the basis of a power analysis. A total of 166 spouses completed caregiver surveys on burden and other caregiving outcomes. RESULTS: Total, objective, and subjective burden levels were low to moderate. Although no burden differences were found between groups, men had higher total burden but more positive caregiving outcomes. Future outlook and social activities were less positive in the 6-month group. Burden levels were not lower, nor were caregiving outcomes higher, in the 12-month group, suggesting a steady caregiving demand across the first year after coronary artery bypass graft surgery. CONCLUSION: Longitudinal investigations are needed to understand burden and caregiving outcomes over time and the impact of burden on spousal and patient recovery outcomes.

Correlates of caregiver burden after coronary artery bypass surgery.

BACKGROUND: Coronary artery bypass (CAB) patients often rely on spouses for care and assistance during recovery after surgery. Caregiving can be stressful and meaningful depending upon the interplay of many factors not completely understood. These factors may affect the spouse caregiver's health-related quality of life (HRQL), which may impact ability to care for the CAB patient. OBJECTIVE: To investigate patient-spouse caregiver relationship and role variables associated with caregiver burden during the first year after CAB surgery. METHODS: Using a cross-sectional design, a convenience sample of CAB spouses was recruited at 3, 6, or 12 months. Spouses (n = 166) completed a survey that included perceptions of patient health status, caregiver burden and other caregiving variables, and caregiver HRQL. RESULTS: Higher burden scores were associated with patient's gender (female), poorer patient health status, lower caregiver mental HRQL, increased personal gain, and increased caregiver competence. These correlates explained 38% of the variance in caregiver burden. DISCUSSION: Only poorer patient health status and lower caregiver mental HRQL were supported by previous research in this population. Positive relationships between burden and caregiver competence and personal gain may be a reflection that spouse caregivers were invested and working hard. They felt satisfied from enhancement of self but were burdened from their caregiving role, providing support for a previously described two-domain caregiving model. Caregiver screening is essential to identify spouses at high risk for negative outcomes. Longitudinal research is needed to identify the correlates and predictors most likely to influence burden and caregiver gain over time, and to more fully understand caregiving in the CAB population.

Coronary artery bypass graft surgery and cognitive performance.

BACKGROUND: Some studies have indicated a decline in patients' cognitive performance after coronary artery bypass graft surgery. OBJECTIVE: To evaluate cognitive performance before and after coronary artery bypass graft surgery. METHODS: Patients' cognitive performance before and after coronary artery bypass graft surgery was evaluated in a prospective observational multicenter study in 5 academic medical centers. A total of 242 men and 123 women were evaluated before surgery; 333 men and 216 women, 5 to 11 months after surgery (197 men and 99 women were evaluated both before and after surgery). Verbal ability, attention/concentration, logical/verbal and visual memory, and facial recognition were measured. Data on demographic, medical, and psychosocial characteristics also were collected. RESULTS: After surgery, patients' overall performance improved (P < .001) for attention/concentration, verbal fluency, and logical/verbal memory. Patients with more education (high school or greater) performed better on each test (P < .001) than did patients with less education. No strong effects of sex or age on cognitive performance were observed before or after surgery, and no important differences in sex, age, or education were associated with changes in scores from before to after surgery. CONCLUSION: On average, cognitive performance improved rather than declined after coronary artery bypass graft surgery. The improvements were consistent across sex, age, and education.

Correlates of neurocognitive function of patients after off-pump coronary artery bypass surgery.

BACKGROUND: Decreases in neurocognitive function have been reported in patients who have undergone off-pump coronary artery bypass surgery; however, few investigators have examined the correlates of the decreases. OBJECTIVES: To explore and determine the correlates of neurocognitive function at the time of discharge from the hospital in patients undergoing off-pump coronary artery bypass surgery. METHODS: Patients undergoing off-pump coronary artery bypass surgery at Abbott Northwestern Hospital, Minneapolis, Minn, were administered tests of neuro-cognition (cognition and motor function), anxiety, depression, and quality of life preoperatively (within 72 hours of surgery) and postoperatively (at least 72 hours after surgery but before discharge from the hospital). RESULTS: A total of 54 patients (79.6% men), mean age 64.5 years, completed tests both preoperatively and postoperatively. When baseline function was controlled for, increased age and new-onset atrial fibrillation (F(3,40)=42.97; P<.001) were associated with decreases in postoperative cognitive function; increased age and anxiety (F(3,35)=15.83; P<.001) were associated with decreases in postoperative motor function. CONCLUSION: Older patients, anxious patients, and patients with new-onset atrial fibrillation are at risk for neurocognitive changes after off-pump coronary artery bypass surgery. Further studies with larger sample sizes should be done to examine interventions to reduce preoperative anxiety in these patients. Interventions to prevent postoperative atrial fibrillation should be explored to determine whether the interventions prevent a decline in neurocognitive function.

Early neurocognitive function of patients after off-pump coronary artery bypass surgery.

DESIGN: This was a prospective, descriptive study. SETTING: The study took place in cardiovascular units at a large urban metropolitan, midwestern tertiary care hospital. SAMPLE: Fifty-four patients undergoing off-pump coronary artery bypass surgery were included. OUTCOME MEASURES: Outcome measures were neurocognition preoperatively at baseline (within 72 hours of surgery) and postoperatively (at least 72 hours after surgery but before discharge). RESULTS: In neurocognitive tests of cognition (memory, language, and attention) there was an improvement in the cognitive composite from the preoperative baseline to the postoperative follow-up (P < .001). However, in tests of motor function (motor speed and information processing speed) there was a decline in the motor composite (P = .006). CONCLUSIONS: After off-pump coronary artery bypass surgery, patients had an overall improvement in tests of memory, language, and attention (cognitive composite), but a decline in tests of motor speed and information processing speed (motor composite).

Functional recovery and exercise behavior in men and women 5 to 6 years following coronary artery bypass graft (CABG) surgery.

Improvement following coronary artery bypass graft (CABG) surgery has been reported to be less in women than men. Relationships between exercise behavior and functional status of men and women 5 to 6 years after CABG have not been examined in a representative patient sample. This study compared the 5- to 6-year recovery in a cohort of 184 patients at the Minnesota site of the Post CABG Biobehavioral Study. Data were collected by telephone interview and self-administered questionnaires. Results showed that women had lower physical ( p

Quality of life after coronary artery bypass graft: results from the POST CABG Trial.

OBJECTIVES: The POST CABG (Post Coronary Artery Bypass Graft) Trial showed that aggressive lowering of low-density lipoprotein (LDL) cholesterol levels reduced the progression of atherosclerosis in saphenous vein grafts. In the extended follow-up phase, aggressive lowering of LDL cholesterol levels was associated with reduced rates of clinical events. Low-dose anticoagulation therapy did not reduce the progression of atherosclerosis. We conducted this analysis to determine the effects of both lipid-lowering and low-dose anticoagulation therapy on health-related quality of life (HRQL). DESIGN: Randomized clinical trial, factorial design. SETTING: Outpatients in five tertiary care medical centers. PATIENTS: A cohort of 852 patients enrolled in the POST CABG Trial completed an HRQL questionnaire at baseline, and at the year 2 and year 4 follow-up visits. INTERVENTION: Aggressive LDL cholesterol lowering vs moderate LDL cholesterol lowering, and low-dose warfarin vs placebo. MEASUREMENTS: Domains included emotional status, basic physical and social functioning, perceived health status, symptoms of pain, a variety of physical symptoms, and global life satisfaction. RESULTS: Overall, there were no indications of systematic differences among treatment groups for any of the HRQL parameters at baseline, year 2, or year 4. CONCLUSIONS: These data indicate that patients did not experience detrimental or beneficial effects on HRQL parameters while receiving LDL cholesterol-lowering therapy that had demonstrable benefits for treatment of atherosclerosis.

Comparison of health-related quality-of-life outcomes of men and women after coronary artery bypass surgery through 1 year: findings from the POST CABG Biobehavioral Study.

BACKGROUND: Women undergoing coronary artery bypass graft (CABG) surgery have a worse medical condition and fewer social and financial resources than men. Some studies have found that women recover less well than men after CABG, whereas others have found women's outcomes comparable to those of men. Past studies of health-related quality of life after CABG have too few women for adequate comparison with men and have not included patients whose data are not available at baseline (eg, emergency CABG), limiting generalizability. METHODS: A longitudinal study of symptoms and health-related quality of life was conducted among patients from four clinical centers enrolling both men (n = 405) and women (n = 269) in the Post CABG Biobehavioral Study in the United States and Canada. RESULTS: After 6 weeks from CABG (average 81 days), both men and women had less anxiety and symptoms related to depression than before surgery (P <.001). After 6 months (average 294 days), both men and women improved in physical and social functioning (P <.001). Although changes in scale scores were similar for men and women at each time point, women scored lower than men on these domains (P <.001, adjusted for baseline medical and sociodemographic differences) and had more symptoms related to depression through 1 year after CABG (P =.003). CONCLUSIONS: Both male and female patients improve in physical, social, and emotional functioning after CABG, and recovery over time is similar in men and women. However, women's health-related quality-of-life scale scores remained less favorable than men's through 1 year after surgery.

Heart rate and blood pressure responses to mental stress and clinical cardiovascular events in men and women after coronary artery bypass grafting: the Post Coronary Artery Bypass Graft (Post-CABG) biobehavioral study.

BACKGROUND: The Post-Coronary Artery Bypass Graft (CABG) biobehavioral study measured the heart rate (HR) and blood pressure (BP) responses to mental stress testing (MST) after surgery and prospectively observed the clinical events in patients who had undergone recent CABG surgery. To the extent that CABG surgery restores myocardial blood flow and prevents myocardial ischemia, patients who have recently recovered from CABG surgery may have nearly normal HR and BP responses to MST. METHODS: A study population of 521 patients (351 men,170 women) from the cohort of 759 patients in the Post-CABG biobehavioral Study was monitored during a mirror tracing test (MTT) and a speech test task (STT) at the 6-month post-CABG surgery follow-up. Medical status for as long as 3 years after CABG surgery was ascertained from questionnaires and medical records. RESULTS: The HR and BP responses during MTT and STT were similar to those reported in other studies of healthy individuals and patients without myocardial ischemia during MST. In contrast to results from other studies of patients with coronary artery disease, the quartile of Post-CABG biobehavioral study patients with the greatest responses in HR, systolic BP (SBP) and diastolic BP (DBP) during MST had half the rate of clinical events (10% in 3 years) as the quartile (20%) with the lowest changes in HR and BP (HR, P =.01; SBP, P =.07; DBP, P =.01). CONCLUSIONS: Vigorous HR and BP responses to MST may be markers for a lower risk of incidence of clinical cardiovascular events among patients who have undergone recent CABG surgery.
