Acta Diabetol 2016; 53:543-50. [PMID: 26794497 DOI: 10.1007/s00592-015-0829-6] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2015] [Accepted: 12/11/2015] [Indexed: 12/12/2022]
Abstract
AIM To assess the performance of HbA1c and the 1-h plasma glucose (PG ≥ 155 mg/dl; 8.6 mmol/l) in identifying dysglycemia based on the oral glucose tolerance test (OGTT) from a real-world clinical care setting. METHODS This was a diagnostic test accuracy study. For this analysis, we tested the HbA1c diagnostic criteria advocated by the American Diabetes Association (ADA 5.7-6.4 %) and International Expert Committee (IEC 6.0-6.4 %) against conventional OGTT criteria. We also tested the utility of 1-h PG ≥ mg/dl; 8.6 mmol/l. Prediabetes was defined according to ADA-OGTT guidelines. Spearman correlation tests were used to determine the relationships between HbA1c, 1-h PG with fasting, 2-h PG and indices of insulin sensitivity and β-cell function. The levels of agreement between diagnostic methods were ascertained using Cohen's kappa coefficient (Κ). Receiver operating characteristic (ROC) curve was used to analyze the performance of the HbA1c and 1-h PG test in identifying prediabetes considering OGTT as reference diagnostic criteria. The diagnostic properties of different HbA1c thresholds were contrasted by determining sensitivity, specificity and likelihood ratios (LR). RESULTS Of the 212 high-risk individuals, 70 (33 %) were identified with prediabetes, and 1-h PG showed a stronger association with 2-h PG, insulin sensitivity index, and β-cell function than HbA1c (P < 0.05). Furthermore, the level of agreement between 1-h PG ≥ 155 mg/dl (8.6 mmol/l) and the OGTT (Κ[95 % CI]: 0.40[0.28-0.53]) diagnostic test was stronger than that of ADA-HbA1c criteria 0.1[0.03-0.16] and IEC criteria (0.17[0.04-0.30]). The ROC (AUC[95 % CI]) for HbA1c and 1-h PG were 0.65[0.57-0.73] and 0.79[0.72-0.85], respectively. Importantly, 1-h PG ≥ 155 mg/dl (8.6 mmol/l) showed good sensitivity (74.3 % [62.4-84.0]) and specificity 69.7 % [61.5-77.1]) with a LR of 2.45. The ability of 1-h PG to discriminate prediabetes was better than that of HbA1c (∆AUC: -0.14; Z value: 2.5683; P = 0.01022). CONCLUSION In a real-world clinical practice setting, the 1-h PG ≥ 155 mg/dl (8.6 mmol/l) is superior for detecting high-risk individuals compared with HbA1c. Furthermore, HbA1c is a less precise correlate of insulin sensitivity and β-cell function than the 1-h PG and correlates poorly with the 2-h PG during the OGTT.

[PMID: 27160107 PMCID: PMC4864730 DOI: 10.1186/s10194-016-0608-y] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Accepted: 02/17/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND There is increasing interest in using electronic behavioral interventions as well as mobile technologies such as smartphones for improving the care of chronic disabling diseases such as migraines. However, less is known about the current clinical evidence for the feasibility and effectiveness of such behavioral interventions. OBJECTIVE To review the published literature of behavioral interventions for primary headache disorders delivered by electronic means suitable for use outside of the clinician's office. METHODS An electronic database search of PubMed, PsycINFO, and Embase was conducted through December 11, 2015. All eligible studies were systematically reviewed to examine the modality in which treatment was delivered (computer, smartphone, watch and other), types of behavioral intervention delivered (cognitive behavioral therapy [CBT], biofeedback, relaxation, other), the headache type being treated, duration of treatment, adherence, and outcomes obtained by the trials to examine the overall feasibility of electronic behavioral interventions for headache. RESULTS Our search produced 291 results from which 23 eligible articles were identified. Fourteen studies used the internet via the computer, 2 used Personal Digital Assistants, 2 used CD ROM and 5 used other types of devices. None used smartphones or wearable devices. Four were pilot studies (N ≤ 10) which assessed feasibility. For the behavioral intervention, CBT was used in 11 (48 %) of the studies, relaxation was used in 8 (35 %) of the studies, and biofeedback was used in 5 (22 %) of the studies. The majority of studies (14/23, 61 %) used more than one type of behavioral modality. The duration of therapy ranged from 4-8 weeks for CBT with a mean of 5.9 weeks. The duration of other behavioral interventions ranged from 4 days to 60 months. Outcomes measured varied widely across the individual studies. CONCLUSIONS Despite the move toward individualized medicine and mHealth, the current literature shows that most studies using electronic behavioral intervention for the treatment of headache did not use mobile devices. The studies examining mobile devices showed that the behavioral interventions that employed them were acceptable to patients. Data are limited on the dose required, long term efficacy, and issues related to the security and privacy of this health data. This study was registered at the PROSPERO International Prospective Register of Systematic Reviews (CRD42015032284) (Prospero, 2015).

Abstract
Dietary phosphorus restriction is recommended to help control hyperphosphatemia in hemodialysis patients, but many high-phosphorus foods are important sources of protein. In this review, we examine whether restricting dietary phosphorus compromises protein status in hemodialysis patients. Although dietary phosphorus and protein are highly correlated, phosphorus intakes can range up to 600 mg/day for a given energy and protein intake level. Furthermore, the collinearity of phosphorus and protein may be biased because the phosphorus burden of food depends on: (1) the presence of phosphate additives, (2) food preparation method, and (3) bioavailability of phosphorus, which are often unaccounted for in nutrition assessments. Ultimately, we argue that clinically relevant reductions in phosphorus intake can be made without limiting protein intake by avoiding phosphate additives in processed foods, using wet cooking methods such as boiling, and if needed, substituting high-phosphorus foods for nutritionally equivalent foods that are lower in bioavailable phosphorus.

Abstract
OBJECTIVE To identify the problems experienced by hemodialysis (HD) patients in attempting to follow the HD diet and their relation to energy and nutrient intakes. DESIGN Cross-sectional analysis of baseline data from the BalanceWise Study. SUBJECTS Participants included community-dwelling adults recruited from outpatient HD centers. After excluding participants with incomplete dietary analyses (n = 50), 140 African American and white (40/60%) men and women (52/48%) on chronic intermittent HD for at least 3 months (median 3 years) were included. INTERVENTION Participant responses, on a 5-point Likert scale ranging from "not at all a problem" to "a very important problem for me," to 34 questions pertaining to potential barriers to following the HD diet in the previous 2 months were classified as either a problem (1) or not a problem (2-5). MAIN OUTCOME MEASURE Energy and nutrient intakes determined using the Nutrition Data System for Research® based on 3, non-consecutive, unscheduled, 2-pass 24-hour dietary recalls collected on 1 dialysis and 1 non-dialysis weekday, and 1 non-dialysis weekend day. RESULTS More than half of participants reported having problems related to specific behavioral factors (e.g., feeling deprived), technical difficulties (e.g., tracking nutrients), and physical condition (e.g., appetite), but issues of time and food preparation and behavioral factors tended to be most deterministic of reported dietary intakes. Longer duration of HD was associated with lower intakes of protein, potassium, and phosphorus (P < .05). CONCLUSION Registered dietitian nutritionists should consider issues of time and food preparation, and behavioral factors in their nutrition assessment of HD patients and should continually monitor HD patients for changes in protein intake that may occur over time.

Abstract
Hepatitis C virus (HCV) treatment has the potential to cure the leading cause of cirrhosis and hepatocellular carcinoma. However, only those deemed eligible for treatment have the possibility of this cure. Therefore, understanding the determinants of HCV treatment eligibility is critical. Given that effective communication with and trust in healthcare providers significantly influences treatment eligibility decisions in other diseases, we aimed to understand patient-provider interactions in the HCV treatment eligibility process. This prospective cohort study was conducted in the VA Pittsburgh Healthcare System. Patients were recruited after referral for gastroenterology consultation for HCV treatment with interferon and ribavirin. Consented patients completed semi-structured interviews and validated measures of depression, substance and alcohol use, and HCV knowledge. Two coders analyzed the semi-structured interviews. Factors associated with patient eligibility for interferon-based therapy were assessed using multivariate logistic regression. Of 339 subjects included in this analysis, only 56 (16.5%) were deemed eligible for HCV therapy by gastroenterology (GI) providers. In the multivariate logistic regression, patients who were older (OR = 0.96, 95%CI = 0.92-0.99, p = .049), reported concerns about the GI provider (OR = 0.40, 95%CI = 0.10-0.87, p = 0.02) and had depression symptoms (OR = 0.32, 95%CI = 0.17-0.63, p = 0.001) were less likely to be eligible. Patients described barriers that included feeling stigmatized and poor provider interpersonal or communication skills. In conclusion, we found that patients' perceptions of the relationship with their GI providers were associated with treatment eligibility. Establishing trust and effective communication channels between patients and providers may lower barriers to potential HCV cure.

Abstract
OBJECTIVE To evaluate the efficacy of behavioral counseling combined with technology-based self-monitoring for sodium restriction in hemodialysis (HD) patients. DESIGN Randomized clinical trial. SUBJECTS English literate adults undergoing outpatient, in-center intermittent HD for at least 3 months. INTERVENTIONS Over a 16-week period, both the intervention and the attention control groups were shown 6 educational modules on the HD diet. The intervention group also received social cognitive theory-based behavioral counseling and monitored their diets daily using handheld computers. MAIN OUTCOME MEASURES Average daily interdialytic weight gain (IDWGA) was calculated for every week of HD treatment over the observation period by subtracting the post-dialysis weight at the previous treatment time (t-1) from the pre-dialysis weight at the current treatment time (t), dividing by the number of days between treatments. Three 24-hour dietary recalls were obtained at baseline, 8 weeks, and 16 weeks and evaluated using the Nutrient Data System for Research. RESULTS A total of 179 participants were randomized, and 160 (89.4%) completed final measurements. IDWGA did not differ significantly by treatment group at any time point considered (P > .79 for each). A significant differential change in dietary sodium intake observed at 8 weeks (-372 mg/day; P = .05) was not sustained at 16 weeks (-191 mg/day; P = .32). CONCLUSION The BalanceWise Study intervention appeared to be feasible and acceptable to HD patients although IDWGA was unchanged and the desired behavioral changes observed at 8 weeks were not sustained. Unmeasured factors may have contributed to the mixed findings, and further research is needed to identify the appropriate patients for such interventions.

Abstract
BACKGROUND Metabolic syndrome poses an increased global burden of disease and causes immense financial burden, warranting heightened public health attention. The present study assessed the prevalence and severity of cardiometabolic risk among foreign-born versus US-born blacks, while exploring potential gender-based effects. METHODS A total of 1035 patients from the Metabolic Syndrome Outcome Study (Trial registration: NCT01946659) provided sociodemographic, medical history, and clinical data. General Linear Model (GLM) was used to assess the effects of birthplace and gender on cardiometabolic parameters, adjusting for age differences in the sample. RESULTS Of the sample, 61.6 % were foreign-born blacks (FBB) and 38.4 % were US-born blacks (USB). FBB had significantly lower BMI compared with USB (32.76 ± 0.35 vs. 35.41 ± 0.44, F = 22.57), but had significantly higher systolic blood pressure (136.70 ± 0.77 vs. 132.83 ± 0.98; F = 9.60) and fasting glucose levels than did USB (146.46 ± 3.37 vs. 135.02 ± 4.27; F = 4.40). Men had higher diastolic BP (76.67 ± 0.65 vs. 75.05 ± 0.45; F = 4.20), glucose (146.53 ± 4.48 vs. 134.95 ± 3.07; F = 4.55) and triglyceride levels (148.10 ± 4.51 vs. 130.60 ± 3.09; F = 10.25) compared with women, but women had higher LDL-cholesterol (109.24 ± 1.49 vs. 98.49 ± 2.18; F = 16.60) and HDL-cholesterol levels (50.71 ± 0.66 vs. 42.77 ± 0.97; F = 46.01) than did men. CONCLUSIONS Results showed that birthplace has a significant influence on cardiometabolic profiles of blacks with metabolic syndrome. Patients' gender also had an independent influence on cardiometabolic profile.

Abstract
BACKGROUND Various hospital accreditation and quality assurance entities in the United States have approved and endorsed performance measures promoting alcohol brief intervention (BI) for hospitalized individuals who screen positive for unhealthy alcohol use, the spectrum of use ranging from hazardous use to alcohol use disorders. These performance measures have been controversial due to the limited and equivocal evidence for the efficacy of BI among hospitalized individuals. The few BI trials conducted with hospital inpatients vary widely in methodological quality. While the majority of these studies indicate limited to no effects of BI in this population, none have been designed to account for the most pervasive methodological issue in BI studies presumed to drive study findings towards the null: assessment reactivity (AR). METHODS/DESIGN This is a three-arm, single-site, randomized controlled trial of BI for hospitalized patients at a large academic medical center affiliated with the U.S. Department of Veterans Affairs who use alcohol at hazardous levels but do not have an alcohol use disorder. Participants are randomized to one of three study conditions. Study Arm 1 receives a three-part alcohol BI. Study Arm 2 receives attention control. To account for potential AR, Study Arm 3 receives AC with limited assessment. Primary outcomes will include the number of standard drinks/week and binge drinking episodes reported in the 30-day period prior to a final measurement visit obtained 6 months after hospital discharge. Additional outcomes will include readiness to change drinking behavior and number of adverse consequences of alcohol use. To assess differences in primary outcomes across the three arms, we will use mixed-effects regression models that account for a patient's repeated measures over the timepoints and clustering within medical units. Intervention implementation will be assessed by: a) review of intervention audio recordings to characterize barriers to intervention fidelity; and b) feasibility of participant recruitment, enrollment, and follow-up. DISCUSSION The results of this methodologically rigorous trial will provide greater justification for or against the use of BI performance measures in the inpatient setting and inform organizational responses to BI-related hospital accreditation and performance measures. TRIAL REGISTRATION NCT01602172.

Abstract
INTRODUCTION The association between sleep disturbances and cardiometabolic diseases has been understudied in blacks with metabolic syndrome. METHODS This study is a cross-sectional analysis of the Metabolic Syndrome Outcome Study (MetSO) trial. We assessed insomnia symptoms, sleep duration, and risk for sleep apnea. Multivariate logistic regression models evaluated the association between sleep disturbances with diabetes mellitus (DM) and the combined outcomes of DM and hypertension as well as DM and dyslipidemia. RESULTS The sample consisted of 1,013 participants, mean age of 62 ± 14 years and 61% female. DM was diagnosed in 60% of the sample. Sleep apnea risk was observed in 48% of the sample, while 10% had insomnia symptoms and 65% reported short sleep duration (< 6 hours). Sleep apnea risk, but not insomnia or sleep duration, was associated with DM (OR 1.66; 95% CI 1.21-2.28), adjusting for age, sex, income, obesity (BMI ≥ 30 kg/m(2)), tobacco use, alcohol use, hypertension, dyslipidemia, and depression. In fully adjusted models, sleep apnea risk was associated with the combined outcome of DM-hypertension (OR 1.95; 95% CI 1.42-2.69), but not with diabetes-dyslipidemia. CONCLUSION We observed a strong association between sleep apnea risk and diabetes mellitus among blacks with metabolic syndrome.

Abstract
Depressive symptoms and pain are common in patients on chronic hemodialysis (HD), yet their associations with quality of life (QOL) are not fully understood. We sought to characterize the longitudinal associations of these symptoms with QOL. As part of a trial comparing two symptom management strategies in patients receiving chronic HD, we assessed depressive symptoms using the Patient Health Questionnaire-9 (PHQ-9), and pain using the Short Form McGill Pain Questionnaire (SF-MPQ) monthly over 24 months. We assessed health-related QOL (HR-QOL) quarterly using the Short Form 12 (SF-12) and global QOL (G-QOL) using a single-item survey. We used random effects linear regression to analyze the independent associations of depressive symptoms and pain, scaled based on 5-point increments in symptom scores, with HR-QOL and G-QOL. Overall, 286 patients completed 1417 PHQ-9 and SF-MPQ symptom assessments, 1361 SF-12 assessments, and 1416 G-QOL assessments. Depressive symptoms were independently and inversely associated with SF-12 physical HR-QOL scores (β = -1.09; 95% confidence interval [CI]: -1.69, -0.50, P < 0.001); SF-12 mental HR-QOL scores (β = -4.52; 95% CI: -5.15, -3.89, P < 0.001); and G-QOL scores (β = -0.64; 95%CI: -0.79, -0.49, P < 0.001). Pain was independently and inversely associated with SF-12 physical HR-QOL scores (β = -0.99; 95% CI: -1.30, -0.68, P < 0.001) and G-QOL scores (β = -0.12; 95%CI: -0.20, -0.05, P = 0.002); but not with SF-12 mental HR-QOL scores (β = -0.16; 95%CI: -0.050, 0.17, P = 0.34). In patients receiving chronic HD, depressive symptoms and to a lesser extent pain, are independently associated with reduced HR-QOL and G-QOL. Interventions to alleviate these symptoms could potentially improve patients' HR-QOL and G-QOL.

Abstract
BACKGROUND AND OBJECTIVES Depressive symptoms and pain are common in patients receiving chronic hemodialysis, yet their effect on dialysis adherence, health resource utilization, and mortality is not fully understood. This study sought to characterize the longitudinal associations of these symptoms with dialysis adherence, emergency department (ED) visits, hospitalizations, and mortality. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS As part of a trial comparing symptom management strategies in patients receiving chronic hemodialysis, this study prospectively assessed depressive symptoms using the Patient Health Questionnaire 9, and pain using the Short-Form McGill Pain Questionnaire, monthly between 2009 and 2011. This study used negative binomial, Poisson, and proportional hazards regression to analyze the longitudinal associations of depressive symptoms and pain, scaled based on 5-point increments in symptom scores, with missed and abbreviated hemodialysis treatments, ED visits, hospitalizations, and mortality, respectively. RESULTS Among 286 patients, moderate-to-severe depressive symptoms were identified on 788 of 4452 (18%) assessments and pain was reported on 3537 of 4459 (79%) assessments. Depressive symptoms were independently associated with missed (incident rate ratio [IRR], 1.21; 95% confidence interval [95% CI], 1.10 to 1.33) and abbreviated (IRR, 1.08; 95% CI, 1.03 to 1.14) hemodialysis treatments, ED visits (IRR, 1.24; 95% CI, 1.12 to 1.37), hospitalizations (IRR, 1.19; 95% CI, 1.10 to 1.30), and mortality (IRR, 1.40; 95% CI, 1.11 to 1.77). Pain was independently associated with abbreviated hemodialysis treatments (IRR, 1.03; 95% CI, 1.01 to 1.06) and hospitalizations (IRR, 1.05; 95% CI, 1.00 to 1.10). Severe pain was independently associated with abbreviated hemodialysis treatments (IRR, 1.16; 95% CI, 1.06 to 1.28), ED visits (IRR, 1.58; 95% CI, 1.28 to 1.94), and hospitalizations (IRR, 1.22; 95% CI, 1.03 to 1.45), but not mortality (hazard ratio, 1.71; 95% CI, 0.81 to 2.96). CONCLUSIONS Depressive symptoms and pain are independently associated with dialysis nonadherence and health services utilization. Depressive symptoms are also associated with mortality. Interventions to alleviate these symptoms have the potential to reduce costs and improve patient-centered outcomes.

Abstract
Patients with type 2 diabetes have an increased risk for cardiovascular and chronic kidney disease. Superimposed hypertension further increases the risk and is associated with increased dietary sodium intake. There are few data available on dietary sodium intake in type 2 diabetes. The aim of this study was to quantify dietary sodium intake in a cohort of self-referred patients with type 2 diabetes and to identify sociodemographic characteristics associated with it. Sodium intake in this cohort was far greater than current recommendations. Increased awareness of sodium intake in this population might lead to target interventions to reduce sodium intake and potentially improve long-term outcomes.

Abstract
OBJECTIVE To identify characteristics of hemodialysis patients most likely to experience difficulty adhering to sodium restrictions associated with their dietary regimen. DESIGN Secondary analysis using baseline data from an ongoing randomized clinical trial examining the effects of a technology-supported behavioral intervention on dietary sodium intake in hemodialysis patients. SETTING Thirteen dialysis centers in southwestern Pennsylvania. SUBJECTS We included 122 participants (61% women; 48% African American) aged 61 ± 14 years undergoing maintenance, intermittent hemodialysis for end-stage renal disease. MAIN OUTCOME MEASURES Normalized dietary sodium intake, adjusted interdialytic weight gain, perceived problems, and self-efficacy for restricting dietary sodium. RESULTS Younger participants were more likely to report problems managing their hemodialysis diet and low self-efficacy for restricting sodium intake. Consistent with these findings, younger participants had a higher median sodium intake and higher average adjusted interdialytic weight gain. Females reported more problems managing their diet. Race, time on dialysis, and perceived income adequacy did not seem to influence outcome measures. CONCLUSION Our findings suggest that patients who are younger and female encounter more difficulty adhering to the hemodialysis regimen. Hence, there may be a need to individualize counseling and interventions for these individuals. Further investigation is needed to understand the independent effects of age and gender on adherence to hemodialysis dietary recommendations and perceived self-efficacy.

Abstract
BACKGROUND AND OBJECTIVES Past studies that demonstrated that sexual dysfunction is common among women receiving chronic hemodialysis did not distinguish sexual dysfunction/difficulty from sexual inactivity. This study sought to differentiate these in order to elucidate the prevalence of true "sexual dysfunction" in this population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS As part of a clinical trial of symptom management strategies in patients receiving chronic hemodialysis, female sexual function was prospectively assessed monthly for 6 months and quarterly thereafter using the Female Sexual Function Index, to which questions were added differentiating sexual dysfunction/difficulty from sexual inactivity. Beginning in month 7, patients were asked three questions about sexual activity, difficulty, and satisfaction monthly. RESULTS Of the women enrolled in the clinical trial,125 participants completed 1721 assessments between 2009 and 2011. Scores on 574 of 643 (89%) quarterly Female Sexual Function Index assessments were consistent with sexual dysfunction, due largely to sexual inactivity, which was reported on 525 (82%) quarterly assessments. When reported (n=1663), the most frequently described reasons for sexual inactivity were lack of interest in sex (n=715; 43%) and lack of a partner (n=647; 39%), but rarely sexual difficulty (n=36; 2%). When reported (n=1582), women were moderately to very satisfied with their sexual life on 1020 (64%) assessments and on 513 of 671 (76%) assessments in which lack of interest was cited as a reason for sexual inactivity. Women indicated an interest in learning about the causes of and treatment for sexual dysfunction on just 5% of all assessments. CONCLUSIONS Although many women receiving chronic hemodialysis are sexually inactive, few describe sexual difficulty. Most, including those with a lack of interest in sex, are satisfied with their sexual life and few wish to learn about treatment options. These findings suggest that true sexual dysfunction is uncommon in this population and that treatment opportunities are rare.

Abstract
BACKGROUND Although limited health literacy is common in hemodialysis patients, its effects on clinical outcomes are not well understood. STUDY DESIGN Observational study. SETTING & PARTICIPANTS 260 maintenance hemodialysis patients enrolled in a randomized clinical trial of symptom management strategies from January 2009 through April 2011. PREDICTOR Limited health literacy. OUTCOMES Dialysis adherence (missed and abbreviated treatments) and health resource utilization (emergency department visits and end-stage renal disease [ESRD]-related hospitalizations). MEASUREMENTS We assessed health literacy using the Rapid Estimate of Adult Literacy in Medicine (REALM) and used negative binomial regression to analyze the independent associations of limited health literacy with dialysis adherence and health resource utilization over 12-24 months. RESULTS 41 of 260 (16%) patients showed limited health literacy (REALM score, ≤60). There were 1,152 missed treatments, 5,127 abbreviated treatments, 552 emergency department visits, and 463 ESRD-related hospitalizations. Limited health literacy was associated independently with an increased incidence of missed dialysis treatments (missed, 0.6% vs 0.3%; adjusted incidence rate ratio [IRR], 2.14; 95% CI, 1.10-4.17), emergency department visits (annual visits, 1.7 vs 1.0; adjusted IRR, 1.37; 95% CI, 1.01-1.86), and hospitalizations related to ESRD (annual hospitalizations, 0.9 vs 0.5; adjusted IRR, 1.55; 95% CI, 1.03-2.34). LIMITATIONS Generalizability and potential for residual confounding. CONCLUSIONS Patients receiving maintenance hemodialysis who have limited health literacy are more likely to miss dialysis treatments, use emergency care, and be hospitalized related to their kidney disease. These findings have important clinical practice and cost implications.

Abstract
BACKGROUND AND OBJECTIVES Pain, erectile dysfunction (ED), and depression are common yet frequently untreated in chronic hemodialysis patients. This study compared two management strategies for these symptoms in this patient population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Pain, ED, and depression were assessed monthly during an observation usual care phase. Patients were then randomized to 12-month participation in either a feedback arm in which these symptoms were assessed monthly, renal providers were informed of patients' symptoms, and treatment was left treatment at their discretion; or a nurse management arm in which symptoms were assessed monthly and trained nurses were used to evaluate patients and generate and facilitate the implementation of treatment recommendations. RESULTS Of 288 patients enrolled into observation between January 1, 2009 and March 30, 2010, 220 (76%) were randomized. Compared with the feedback approach, the results (shown as Δ symptom score [95% confidence interval]) indicated that nurse management was not associated with improved pain (0.49 [-0.56, 1.54]), ED (0.20 [-0.55, 0.95]), or depression (0.32 [-0.94, 1.58]). Relative to their symptoms during observation, feedback patients experienced small, statistically significant improvements in pain (-0.98 [-1.67, -0.28]), ED (-0.98 [-1.54, -0.41]), and depression (-1.36 [-2.19, -0.54]), whereas nurse management patients experienced small, statistically significant improvements in ED (-0.78 [-1.41, -0.15]) and depression (-1.04 [-2.04, -0.04]). CONCLUSIONS Compared with informing renal providers of their patients' pain, ED, and depression and leaving management at their discretion, a nurse-implemented management strategy does not improve these symptoms. Both approaches modestly reduced symptoms relative to usual care.

Abstract
BACKGROUND Behavioral research to improve lifestyle in broadly defined populations of patients with type 2 diabetes is limited. OBJECTIVE We evaluated a behavioral intervention featuring technology-based self-monitoring on biophysiologic outcomes of glycemic control and markers of cardiovascular risk. DESIGN In this single-site, randomized clinical trial, participants were stratified by good and poor glycemic control (glycated hemoglobin <8% or ≥8%) and absence or presence of kidney disease, (estimated glomerular filtration rate ≥60 or <60 mL/min) and randomized within strata. Measurements were obtained at 0, 3, and 6 months. PARTICIPANTS/SETTING Self-referred, community-dwelling adults with type 2 diabetes mellitus. INTERVENTION The intervention group received Social Cognitive Theory-based counseling paired with technology-based self-monitoring, and results were compared with an attention control group. MAIN OUTCOME MEASURES Glycated hemoglobin, fasting serum glucose, lipid levels, blood pressure, weight, body mass index, and waist circumference were evaluated. STATISTICAL ANALYSES PERFORMED Mean differences within and between randomization groups were compared over time. Intervention effects over time were estimated using random intercept models. RESULTS Two hundred ninety-six subjects were randomized, 256 (86.5%) completed 3-month and 246 (83.1%) completed 6-month assessments. Glycated hemoglobin was reduced in the intervention group by 0.5% at 3 months and 0.6% at 6 months (P<0.001 for each), and the control group by 0.3% (P<0.001) at 3 months and 0.2% (P<0.05) at 6 months; but between-group differences were not significant. In those with baseline glycated hemoglobin ≥8% and estimated glomerular filtration rate ≥60 mL/min, glycated hemoglobin was reduced in the intervention group by 1.5% at 3 months and 1.8% at 6 months (P<0.001 for each), and the control group by 0.9% (P<0.001) at 3 months and 0.8% (P<0.05) at 6 months; but between-group differences were not significant. In random intercept models, the estimated reduction in glycated hemoglobin of 0.29% was not significant. CONCLUSIONS Two behavioral approaches to improving general lifestyle management in individuals with type 2 diabetes mellitus were effective in improving glycemic control, but no significant between-group differences were observed.

Abstract
BACKGROUND Telemonitoring interventions featuring transmission of home glucose records to healthcare providers have resulted in improved glycemic control in patients with diabetes. No research has addressed the intensity or duration of telemonitoring required to sustain such improvements. PURPOSE The DiaTel study (10 January 2005 to 1 November 2007) compared active care management (ACM) with home telemonitoring (n=73) to monthly care coordination (CC) telephone calls (n=77) among veterans with diabetes and suboptimal glycemic control. The purpose of the DiaTel Extension was to assess whether initial improvements could be sustained with interventions of the same or lower intensity among participants who re-enrolled in a 6-month extension of DiaTel. METHODS DiaTel participants receiving ACM were re-assigned randomly to monthly CC calls with continued telemonitoring but no active medication management (ACM-to-CCHT, n=23) or monthly CC telephone calls (ACM-to-CC, n=21). DiaTel participants receiving CC were re-assigned randomly to continued CC (CC-to-CC, n=28) or usual care (UC, ie, CC-to-UC, n=29). Hemaglobin A1c (HbA1c) was assessed at 3 and 6 months following re-randomization. RESULTS Marked HbA1c improvements observed in DiaTel ACM participants were sustained 6 months after re-randomization in both ACM-to-CCHT and ACM-to-CC groups. Lesser HbA1c improvements observed in DiaTel CC participants were sustained in both CC-to-CC and CC-to-UC groups. No benefit was apparent for continued transmission of glucose data among DiaTel ACM participants or continued monthly telephone calls among DiaTel CC participants 6 months after re-randomization. CONCLUSION Significant improvements in HbA1c achieved using home telemonitoring and active medication management for 6 months were sustained 6 months later with interventions of decreased intensity in VA Health System-qualified veterans.

A qualitative study of anticipated barriers and facilitators to the implementation of nurse-delivered alcohol screening, brief intervention, and referral to treatment for hospitalized patients in a Veterans Affairs medical center. Addict Sci Clin Pract 2012; 7:7. [PMID: 23186245 PMCID: PMC3533719 DOI: 10.1186/1940-0640-7-7] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2011] [Accepted: 05/02/2012] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND Unhealthy alcohol use includes the spectrum of alcohol consumption from risky drinking to alcohol use disorders. Routine alcohol screening, brief intervention (BI) and referral to treatment (RT) are commonly endorsed for improving the identification and management of unhealthy alcohol use in outpatient settings. However, factors which might impact screening, BI, and RT implementation in inpatient settings, particularly if delivered by nurses, are unknown, and must be identified to effectively plan randomized controlled trials (RCTs) of nurse-delivered BI. The purpose of this study was to identify the potential barriers and facilitators associated with nurse-delivered alcohol screening, BI and RT for hospitalized patients. METHODS We conducted audio-recorded focus groups with nurses from three medical-surgical units at a large urban Veterans Affairs Medical Center. Transcripts were analyzed using modified grounded theory techniques to identify key themes regarding anticipated barriers and facilitators to nurse-delivered screening, BI and RT in the inpatient setting. RESULTS A total of 33 medical-surgical nurses (97% female, 83% white) participated in one of seven focus groups. Nurses consistently anticipated the following barriers to nurse-delivered screening, BI, and RT for hospitalized patients: (1) lack of alcohol-related knowledge and skills; (2) limited interdisciplinary collaboration and communication around alcohol-related care; (3) inadequate alcohol assessment protocols and poor integration with the electronic medical record; (4) concerns about negative patient reaction and limited patient motivation to address alcohol use; (5) questionable compatibility of screening, BI and RT with the acute care paradigm and nursing role; and (6) logistical issues (e.g., lack of time/privacy). Suggested facilitators of nurse-delivered screening, BI, and RT focused on provider- and system-level factors related to: (1) improved provider knowledge, skills, communication, and collaboration; (2) expanded processes of care and nursing roles; and (3) enhanced electronic medical record features. CONCLUSIONS RCTs of nurse-delivered alcohol BI for hospitalized patients should include consideration of the following elements: comprehensive provider education on alcohol screening, BI and RT; record-keeping systems which efficiently document and plan alcohol-related care; a hybrid model of implementation featuring active roles for interdisciplinary generalists and specialists; and ongoing partnerships to facilitate generation of additional evidence for BI efficacy in hospitalized patients.

Abstract
Adequate participant recruitment is critical for the successful execution of research studies involving human subjects. Participant recruitment can be particularly challenging when the intended study participants are health care providers as opposed to patients. Discussions of the challenges and successful strategies associated with provider recruitment are limited, particularly regarding providers other than physicians and settings outside of primary care. Using a case study format, we present our experiences recruiting inpatient nurses into a study which involved focus group methodology at a United States Veterans Health Administration facility. We describe the initial logistical and ethical issues involved, various challenges we encountered, and five successful action strategies used during a second recruitment wave addressing logistical issues; on-site recruitment; increased scheduling flexibility and peer-to-peer recruitment; attention to the sensitive nature of the research topic; and increased involvement of stakeholders. In conclusion, we advocate for multimodal recruitment strategies that facilitate ongoing investigator-clinician partnerships.

Abstract
INTRODUCTION Chronic kidney disease is a condition characterized by the deterioration of the kidney's ability to remove waste products from the body. Although treatments to slow the progression of the disease are available, chronic kidney disease may eventually lead to a complete loss of kidney function. Previous studies have shown that physical activities of moderate intensity may have renal benefits. Few studies have examined the effects of total movement on kidney function. The purpose of this study was to determine the association between time spent at all levels of physical activity intensity and sedentary behavior and kidney function. METHODS Data were obtained from the 2003-2004 and 2005-2006 National Health and Nutrition Examination Survey, a cross-sectional study of a complex, multistage probability sample of the US population. Physical activity was assessed using an accelerometer and questionnaire. Glomerular filtration rate (eGFR) was estimated using the Modification of Diet in Renal Disease study formula. To assess linear associations between levels of physical activity and sedentary behavior with log-transformed estimated GFR (eGFR), linear regression was used. RESULTS In general, physical activity (light and total) was related to log eGFR in females and males. For females, the association between light and total physical activity with log eGFR was consistent regardless of diabetes status. For males, the association between light and total physical activity and log eGFR was only significant in males without diabetes. CONCLUSIONS When examining the association between physical activity, measured objectively with an accelerometer, and kidney function, total and light physical activities were found to be positively associated with kidney function.

Abstract
OBJECTIVE The dialysis dietary regimen is complicated, and computer-based dietary self-monitoring may be useful for helping dialysis patients manage their dietary regimen. In this report, we describe dietary self-monitoring rates among study participants randomized to the intervention arms of 2 pilot studies. METHODS Both studies tested similar interventions involving dietary counseling paired with personal digital assistant-based self-monitoring. One study was performed in hemodialysis (HD) and one in peritoneal dialysis (PD) patients. RESULTS HD intervention participants entered an average of 244.9 meals (median = 288; interquartile range [IQR]: 186 to 342) over the 16-week intervention, 2.2 meals per day (median = 2.6; IQR: 1.7 to 3.1), and 73% of expected meals (median = 86; IQR: 55 to 102), assuming intake of 3 meals per day. At least some meals were entered in 87% of the observed weeks (median = 100%; IQR: 81 to 100). PD intervention participants entered an average of 212.1 meals (median = 203; IQR: 110 to 312) over the 16-week intervention, 1.9 meals per day (median = 1.8; IQR: 1 to 2.8), and 63% of expected meals (median = 60; IQR: 33 to 93), assuming 3 meals per day. At least some meals were entered in 80% of the observed weeks (median = 94; IQR: 50 to 100). CONCLUSION These HD and PD patients demonstrated excellent rates of self-monitoring. Additional research with a larger sample is required to confirm these findings.
