Parental versus non-parental-directed donation: an 11-year experience of infectious disease testing at a pediatric tertiary care blood donor center.

BACKGROUND: Directed donation is associated with a higher prevalence of donations that are positive for infectious disease markers; however, little is known about the positive rates among parental-directed, non-parental-directed, and allogeneic donations. STUDY DESIGN AND METHODS: We reviewed blood-collection records from January 1997 through December 2008, including infectious disease results, among parental, non-parental, and community donations. Infectious disease rates were compared by Mann-Whitney U test. RESULTS: In total, 1532 parental, 4910 non-parental, and 17,423 community donations were examined. Among parental donors, the median rate of positive infectious disease testing was 8.66% (interquartile range (IQR), 4.49%) for first-time donors and 1.26% (IQR, 5.86%) for repeat donors; among non-parental donors, the rate was 1.09% (IQR, 0.98%) for first-time donors and 0% (IQR, 0.83%) for repeat donors; and, among community donors, the rate was 2.95% (IQR, 1.50%) for first-time donors and 0.45% (IQR, 0.82%) for repeat donors. The mean rate of positive infectious disease testing for first-time parental donors was significantly higher (7.63%), whereas all repeat donors had similar rates. However, the rate of positive infectious disease testing among first-time non-parental donors was significantly lower than that in the other groups, especially for the period from 2001 through 2008. CONCLUSION: First-time non-parental and community donors had significantly higher infectious disease risk than the respective repeat donors. First-time parental donors had the highest rates of positive infectious disease testing. We suggest that first-time parental blood donation should be discouraged. Repeat community donors or first-time non-parental donors provide a safer alternative. These findings can foster better patient education, donor selection, and possibly a reduced risk of infectious disease.

Blood Product Utilization Among Trauma and Nontrauma Massive Transfusion Protocols at an Urban Academic Medical Center.

BACKGROUND: Hospital-wide massive transfusion protocols (MTPs) primarily designed for trauma patients may lead to excess blood products being prepared for nontrauma patients. This study characterized blood product utilization among distinct trauma and nontrauma MTPs at a large, urban academic medical center. METHODS: A retrospective study of blood product utilization was conducted in patients who required an MTP activation between January 2011 and December 2015 at an urban academic medical center. Trauma MTP containers included 6 red blood cell (RBC) units, 5 plasma units, and 1 unit of apheresis platelets. Nontrauma MTP containers included 6 RBC and 3 plasma units. RESULTS: There were 334 trauma MTP activations, 233 nontrauma MTP activations, and 77 nontrauma MTP activations that subsequently switched to a trauma MTP ("switched activations"). All nontrauma MTP activations were among bleeding patients who did not have a traumatic injury (100% [233/233]). Few patients with a nontrauma activation required ad hoc transfusion of RBC units (1.3% [95% confidence interval {CI}, 0.3%-3.7%]) or plasma (3.4% [95% CI, 1.5%-6.7%]), and only 45.5% (95% CI, 39.0%-52.1%) required ad hoc transfusion of apheresis platelets. Compared to trauma and switched activations, nontrauma activations transfused a lower median number of RBC, plasma, and apheresis platelet units (P < .001 for all comparisons). There was also a lower median number of prepared but unused plasma units for nontrauma activations (3; [interquartile range {IQR}, 3-5]) compared to trauma (7; [IQR, 5-10]; P < .001) and switched activations (8; [IQR, 5-11]; P < .001). The median number of unused apheresis platelet units was 1 (IQR, 1-2) for trauma activations and 0 (IQR, 0-1) for switched activations. There was a high proportion of trauma and switched activations in which all of the prepared apheresis platelet units were unused (28.1% [95% CI, 23.4%-33.3%] and 9.1% [95% CI, 3.7%-17.8%], respectively). CONCLUSIONS: The majority of initial nontrauma MTP activations did not require a switch to a trauma MTP. Patients remaining under a nontrauma MTP activation were associated with a lower number of transfused and unused plasma and apheresis platelet units. Future studies evaluating the use of hospital-wide nontrauma MTPs are warranted since an MTP designed for nontrauma patient populations may yield a key strategy to optimize blood product utilization in comparison to a universal MTP for both trauma and nontrauma patients.

The potential utility of drinking motive questions to screen at-risk drinking in socially anxious patients.

BACKGROUND: Drinking motives are thought to be important mediators of the relationship between social anxiety and alcohol use. This project evaluates whether specific drinking motives accurately reflect alcohol dependence. If so, brief questions about drinking motives could serve as valuable alcohol screening tools with socially anxious patients. METHODS: This investigation was a secondary analysis of an existing data set of 83 subjects with social anxiety disorder and at-risk alcohol use. The relationship between Drinking Motives Questionnaire (DMQ-R-5) subscales and alcohol dependence was evaluated. RESULTS: Coping-Depression was the only subscale that contributed to the unique prediction of a diagnosis of alcohol dependence. Additionally, two items (i.e. "to cheer up when you're in a bad mood" and "to forget painful memories") predicted a diagnosis of alcohol dependence above and beyond their association with each other. CONCLUSIONS: Among patients with social anxiety, two specific questions on the DMQ-R-5 could provide a useful screen for health professionals to predict alcohol dependence. It may be fruitful to specifically target the motives of "to cheer up when you're in a bad mood" and "to forget painful memories" when providing advice during brief interventions.

Client attitudes toward alcohol use self-report.

Because psychiatric illnesses and problematic alcohol use frequently co-occur and heavy alcohol use can exacerbate depression and anxiety, mental health clinicians should perform alcohol-use screenings. The aim of this study was to determine if psychiatric patients would be accepting of their mental health clinician screening them for heavy alcohol use. Using a written survey, patients rated their levels of agreement with 9 statements regarding opinions about alcohol screening by their mental-health providers. They also completed the Alcohol Use Disorders Identification Test-C (AUDIT-C), a screening instrument for heavy alcohol use. One hundred fifty-four patients were surveyed in 2 psychiatric outpatient clinics. Nearly 40% screened positively for heavy alcohol use on the AUDIT-C. Nearly 8 out of 10 psychiatric patients were in favor of being screened for alcohol use by either self-report or biomarkers, independent of AUDIT-C status and gender. Thus, mental health clinicians should not be deterred from alcohol screening by perceived negative attitudes from patients.

Prevalence of problem drinking and characteristics of a single-question screen.

Hazardous drinking and alcohol use disorders (i.e, abuse and dependence) are common in Emergency Departments (EDs). This study examined 1) the prevalence of these conditions among ED patients and 2) characteristics of a single screening question (having consumed at least five drinks for males or four for females during a single day). Data from the National Epidemiologic Survey on Alcohol and Related Conditions were analyzed. Logistic regression for clustered data was used to estimate the relative risk for past-year ED use associated with hazardous drinking, abuse, and dependence. Contingency tables were analyzed to estimate the sensitivity and specificity of the single-question screen for detecting these conditions. Hazardous drinking was not associated with ED utilization. Alcohol abuse was associated with a relative risk of 1.3 (95% confidence interval [CI] 1.1-1.5) and alcohol dependence with a relative risk of 1.9 (95% CI 1.6-2.2). For current drinkers, the single question screen was 0.96, 0.85, and 0.90 sensitive for hazardous drinking, alcohol abuse, and alcohol dependence, respectively. Individuals with a positive screen in the past year were considered at least hazardous drinkers, and specificity was 0.80, 0.64, and 0.65 for hazardous drinking, abuse, and dependence, respectively. Specificity was modestly increased in women. Most problem drinkers were hazardous drinkers, but only severe alcohol use disorders were particularly prevalent in the ED. The single heavy-drinking-day item appears sensitive for problem drinking. Positive tests must be followed by additional assessment to differentiate hazardous drinking from alcohol use disorders.

Preliminary evaluation of phosphatidylethanol and alcohol consumption in patients with liver disease and hypertension.

AIMS: The goal of this preliminary study was to evaluate the relationship between blood phosphatidylethanol (PEth) and recent drinking in patients with liver disease and hypertension. METHODS: Twenty-one patients with liver disease and 21 patients with essential hypertension were recruited at an academic medical center. Alcohol consumption was estimated using validated self-report methods, and blood PEth was measured by HPLC-MS/MS at a contracted laboratory. Nonparametric comparisons were made between abstainers/light drinkers, moderate drinkers consuming between 1 and 3 drinks per day, and those drinking above this level. Regression methods were used to estimate the effects of liver disease, gender, and age on the relationship between PEth and alcohol use, and to estimate the strength of the linear relationship between PEth and drinking. RESULTS: PEth differed significantly between the three drinking groups (P < 0.001). The relationship between PEth and alcohol did not differ between hypertension and liver disease patients (P = 0.696), nor by gender and age. While there was substantial variability between subjects in the PEth concentration given a similar level of reported drinking, the amount of ethanol consumed was strongly associated with the PEth concentration (P < 0.001). CONCLUSION: Results support PEth measurement by HPLC-MS/MS as a promising marker of past 1- to 2-week moderate to heavy alcohol consumption in patients with and without liver disease. PEth appears useful for differentiating abstinence or light drinking from moderate to heavy consumption, but may have limited utility for differentiating moderate from heavy alcohol use.

Wire tethering or 'bowstringing' as a long-term hardware-related complication of deep brain stimulation.

BACKGROUND: Widely reported long-term complications following implantation of deep brain stimulation (DBS) hardware include breakage of electrode leads, internal pulse generator (IPG) failure, skin erosions and infection. Here we report on a rarely described problem that arises from formation of scar tissue adhesions around the DBS extension wire(s). Over time, this scar tissue can become tight and pronounced, protruding noticeably beneath the skin ('bowstringing' in reference to its tight bow-like appearance) and leading to significant limitation of movement and discomfort. We term this 'wire tethering'. RESULTS: We describe 6 patients with moderate to severe wire tethering. Review of our experience suggests an association of wire tethering with the passage of two extension wires on the same side as is done when using a dual-channel IPG. Five of the patients required surgical revision of the extension wires due to the magnitude of the discomfort, limitation of movement and appearance. Removing the wires was insufficient in the most severe case, necessitating transection of the scar in several places, which was done with the extension wires in situ in 2 patients. Two patients were treated with removal of the wires alone, and 1 patient did not opt for surgery and the tethering has persisted. CONCLUSION: Wire tethering, or 'bowstringing', is an underrecognized complication of DBS hardware implantation often necessitating surgical revision. The possible etiology of wire tethering is discussed as well as suggestions for its avoidance.

Alcohol screening and brief counseling in a primary care hypertensive population: a quality improvement intervention.

AIMS: To determine the effect of an intervention to improve alcohol screening and brief counseling for hypertensive patients in primary care. DESIGN: Two-year randomized, controlled trial. SETTING/PARTICIPANTS: Twenty-one primary care practices across the United States with a common electronic medical record. INTERVENTION: To promote alcohol screening and brief counseling. Intervention practices received site visits from study personnel and were invited to annual network meetings to review the progress of the project and share improvement strategies. MEASUREMENTS: Main outcome measures included rates of documented alcohol screening in hypertensive patients and brief counseling administered in those diagnosed with high-risk drinking, alcohol abuse or alcohol dependence. Secondary outcomes included change in blood pressure among patients with these diagnoses. FINDINGS: Hypertensive patients in intervention practices were significantly more likely to have been screened after 2 years than hypertensive patients in control practices [64.5% versus 23.5%; adjusted odds ratio (OR) = 8.1; 95% confidence interval (CI) 1.7-38.2; P < 0.0087]. Patients in intervention practices diagnosed with high-risk drinking, alcohol abuse or alcohol dependence were more likely than those in control practices to have had alcohol counseling documented (50.5% versus 29.6%; adjusted OR = 5.5, 95% CI 1.3-23.3). Systolic (adjusted mean decline = 4.2 mmHg, P = 0.036) and diastolic (adjusted mean decline = 3.3 mmHg, P = 0.006) blood pressure decreased significantly among hypertensive patients receiving alcohol counseling. CONCLUSIONS: Primary care practices receiving an alcohol-focused intervention over 2 years improved rates of alcohol screening for their hypertensive population. Implementation of alcohol counseling for high-risk drinking, alcohol abuse or alcohol dependence also improved and led to changes in patient blood pressures.

Febrile myoclonus: an underreported, benign condition in infancy often misinterpreted as febrile seizures.

Massive myoclonic jerks, often presenting in a dramatic fashion during a febrile illness, have rarely been reported and have usually been related to as febrile seizures. Febrile myoclonus is usually a benign phenomenon with no neurological sequelae. However, it may be impressive enough to provoke unnecessary diagnostic workup and treatment in these patients. Thus, its recognition by the emergency room or by the primary care physician is important to provide reassurance to the parents or caregivers and to prevent unwarranted hospitalizations and diagnostic procedures such as lumbar puncture and electroencephalogram. We describe 3 cases of febrile myoclonus and briefly review this subject.

Alcohol screening in dental patients: the prevalence of hazardous drinking and patients' attitudes about screening and advice.

BACKGROUND: Because heavy drinking is a risk factor for oral cancer, dentists should screen patients for alcohol use. The authors investigated heavy drinking in dental patients and patients' attitudes about alcohol screening. METHODS: A convenience sample of 408 patients attending an emergency walk-in dental clinic served as subjects. Patients completed the Alcohol Use Disorders Identification Test-C (AUDIT-C), a three-item alcohol screening test, and an opinion survey regarding attitudes about the acceptability of alcohol screening and counseling by dentists. RESULTS: One in four patients had positive screening results for heavy alcohol use. The majority of subjects (> 75 percent) were in support of dentists' inquiries and advice about alcohol use. Age, sex and drinking status were not predictive of patients' opinions about alcohol screening. CONCLUSIONS: One hundred three of the dental patients exhibited evidence of hazardous alcohol consumption, a risk factor for oropharyngeal cancer. The majority of patients reported that they would readily accept alcohol screening and alcohol counseling by dentists. CLINICAL IMPLICATIONS: Because studies have shown that some dentists hesitate to screen for alcohol use because of a belief that screening is unacceptable to patients, these results may encourage a change in practice.

Health-related quality of life in urban surgical emergency department patients: comparison with a representative German population sample.

BACKGROUND: Patients in emergency departments show a high prevalence of substance use. Quality of life is associated with substance use as well as socioeconomic status. Little is known about quality of life in substance-abusing young patients with minor trauma. METHODS: An investigation in an Emergency Department in an inner city university hospital was conducted during 8 months. Overall, 1,596 patients completed the SF-36 and an established SES-questionnaire and were screened for substance use (harmful alcohol consumption (>or= 8 points in men and >or= 5 points in women on the Alcohol Use Disorders Identification Test (AUDIT), smoking and illicit drug use). Results were compared with a representative German population sample (German Federal Health Survey 1998). RESULTS: Median age of participants was 32 years and 61.8% were male. Mean physical component summary score (PCS) of the Short Form-36 Health Survey (SF-36) was 53.4 +/- 8.3 points and significantly higher than the age and gender-stratified German Federal Health Survey-data. Mean mental component summary score (MCS) was 47.9 +/- 10.0 points and significantly lower than the age and gender-stratified German Federal Health Survey-data. In Emergency Department patients, prevalence of substance use was high and harmful alcohol consumption and illicit drug use were strongly associated with impaired mental health. Education and occupational status were strongly positively associated with physical health. CONCLUSION: We conclude that there is a high prevalence of substance use in young patients with minor trauma and mental quality of life is impaired. Screening and brief intervention strategies to reduce substance-use associated disorders should consider these findings.

Excessive alcohol consumption and hypertension: clinical implications of current research.

Substantial evidence demonstrates that: 1) heavy alcohol consumption (three or more standard drinks per day) is associated with and predictive of hypertension; 2) reduction in alcohol consumption is associated with a significant dose-dependent lowering of mean systolic and diastolic blood pressure; and 3) physician advice can reduce heavy drinking in hypertensive patients. These findings suggest that the routine evaluation of alcohol consumption in hypertensive patients is warranted. The Alcohol Use Disorders Identification Test-C (AUDIT-C), a brief, three-question screening test, is useful in this regard. Alcohol biomarkers can also play a role in detecting and monitoring heavy drinking in hypertensive patients whose self-reports on the AUDIT-C are suspect. Carbohydrate-deficient transferrin, a new alcohol biomarker with high specificity, can provide objective data for feedback and counseling. A routine search for excessive use of alcohol, along with brief interventions and monitoring, can have a major impact on reducing the prevalence of hypertension in the general population.

Do negative emotions predict alcohol consumption, saturated fat intake, and physical activity in older adults?

This study examined anger, depression, and stress as related to alcohol consumption, saturated fat intake, and physical activity. Participants were 23 older adults enrolled in either an outpatient or in-residence executive health program. Participants completed (a) a health-risk appraisal assessing medical history and current health habits, (b) the State-Trait Anger Expression Inventory (STAXI), and (c) the Center for Epidemiological Studies-Depression Questionnaire. Bivariate correlations revealed that anxiety was negatively correlated with alcohol consumption. High levels of depression, trait anger, and outward anger expression style were positively associated with saturated fat intake. Trait anger was also associated with less aerobic exercise. Inward anger expression was positively correlated with regular participation in strength training. Results suggest that anger, anger expression style, and depression interact with healthy and unhealthy behavior patterns and that these interactions may be complex.

Biochemical alcohol screening in primary health care.

Alcohol biomarkers such as carbohydrate-deficient transferrin (CDT) and gamma-glutamyltransferase (GGT) have significant potential for enhancing the quality of medical treatment in primary health care settings. Recent studies demonstrate that these laboratory tests can help the general practitioner in several ways. First, CDT and GGT can detect current heavy drinking in primary care patients with a fair degree of sensitivity (approximately 60% to 70%), with CDT being more specific (approximately 90%). When combined with self-report tests, they can provide a clinically useful alcohol screening battery. Second, elevated CDT and GGT levels have been correlated with specific alcohol-sensitive diseases (e.g., hypertension) and, as such, can serve as risk indicators for those diseases. Third, alcohol biomarkers have proven to be useful in monitoring the effectiveness of brief alcohol interventions with medical patients. Unfortunately, preliminary findings indicate that physicians have little knowledge of current biomarker research as applied to primary health care. Translational studies are needed on methods to facilitate knowledge and use of alcohol biomarkers by general practitioners.

Behavioral medicine in the prevention and treatment of cardiovascular disease.

Cardiac behavioral medicine is the application of behavioral and psychosocial principles to the prevention and treatment of heart disease. Most biomedical cardiovascular risk factors (e.g., high blood lipids, high blood pressure, diabetes) require behavioral and medical interventions. Other risks, including obesity, high-fat eating pattern, smoking, and inactivity, clearly require lifestyle change. Behavioral medicine screening and intervention have been applied to psychosocial risk factors such as depression, hostility, and social isolation. Appropriate assessment of risk factors is essential because research has demonstrated successful prevention of heart disease and reduction of morbidity and mortality in patients with existing disease. Behavioral interventions have been beneficial in improving cardiac outcomes by enhancing compliance with medication taking and dietary/exercise recommendations. Future needs include the study of psychosocial factors in women and ethnic minorities with heart disease and the integration of behavioral medicine with newer medical technologies designed to detect subclinical biomarkers of heart disease.

An online alcohol and oral health curriculum for dental students.

Regular heavy alcohol use can cause or worsen several oral health disorders and is associated with complications during and after dental procedures. Dental student education should provide detailed knowledge of these issues together with skills needed to detect and counsel patients with unhealthy drinking patterns. This project was designed to develop and evaluate a five-module, online program to teach dental students about alcohol and oral health, systemic and oral biological effects of heavy drinking, required changes to treatment protocols for heavy drinkers, reliable methods of alcohol screening, and ways to provide heavy drinkers with brief interventions. Results indicated that the online program resulted in significant changes in knowledge, attitudes, and behavior. This online format could easily be incorporated into an already crowded dental school curriculum, with students learning the material at their own pace and in their own available time.

Integration and sustainability of alcohol screening, brief intervention, and pharmacotherapy in primary care settings.

OBJECTIVE: At-risk drinking and alcohol use disorders are common in primary care and may adversely affect the treatment of patients with diabetes and/or hypertension. The purpose of this article is to report the impact of dissemination of a practice-based quality improvement approach (Practice Partner Research Network-Translating Research into Practice [PPRNet-TRIP]) on alcohol screening, brief intervention for at-risk drinking and alcohol use disorders, and medications for alcohol use disorders in primary care practices. METHOD: Nineteen primary care practices from 15 states representing 26,005 patients with diabetes and/or hypertension participated in a group-randomized trial (early intervention vs. delayed intervention). The 12-month intervention consisted of practice site visits for academic detailing and participatory planning and network meetings for "best practice" dissemination. RESULTS: At the end of Phase 1, eligible patients in early-intervention practices were significantly more likely than patients in delayed-intervention practices to have been screened (odds ratio [OR] = 3.30, 95% CI [1.15, 9.50]) and more likely to have been provided a brief intervention (OR = 6.58, 95% CI [1.69, 25.7]. At the end of Phase 2, patients in delayed-intervention practices were more likely than at the end of Phase 1 to have been screened (OR = 5.18, 95% CI [4.65, 5.76]) and provided a brief intervention (OR = 1.80, 95% CI [1.31, 2.47]). Early-intervention practices maintained their screening and brief intervention performance during Phase 2. Medication for alcohol use disorders was prescribed infrequently. CONCLUSIONS: PPRNet-TRIP is effective in improving and maintaining improvement in alcohol screening and brief intervention for patients with diabetes and/or hypertension in primary care settings.

Organizational attributes and screening and brief intervention in primary care.

Overconsumption of alcohol is well known to lead to numerous health and social problems. Prevalence studies of United States adults found that 20% of patients meet criteria for an alcohol use disorder. Routine screening for alcohol use is recommended in primary care settings, yet little is known about the organizational factors that are related to successful implementation of screening and brief intervention (SBI) and treatment in these settings. The purpose of this study was to evaluate organizational attributes in primary care practices that were included in a practice-based research network trial to implement alcohol SBI. The Survey of Organizational Attributes in Primary Care (SOAPC) has reliably measured four factors: communication, decision-making, stress/chaos and history of change. This 21-item instrument was administered to 178 practice members at the baseline of this trial, to evaluate for relationship of organizational attributes to the implementation of alcohol SBI and treatment. No significant relationships were found correlating alcohol screening, identification of high-risk drinkers and brief intervention, to the factors measured in the SOAPC instrument. These results highlight the challenges related to the use of organizational survey instruments in explaining or predicting variations in clinical improvement. Comprehensive mixed methods approaches may be more effective in evaluations of the implementation of SBI and treatment.

Treating individuals with social anxiety disorder and at-risk drinking: phasing in a brief alcohol intervention following paroxetine.

Paroxetine alone is not sufficient to decrease alcohol use in socially anxious alcoholics seeking anxiety treatment. We tested the hypothesis that adding a brief-alcohol-intervention (BI) to paroxetine would decrease alcohol use. All subjects (N=83) had a diagnosis of social anxiety disorder, endorsed drinking to cope with anxiety, were NIAAA-defined at-risk drinkers, and were randomized to either paroxetine alone, or paroxetine plus BI. Both groups showed significant improvement in both social anxiety severity (F(5,83)=61.5, p<0.0001) and drinking to cope (e.g. F(4,79)=23, p<0.0001) and these two constructs correlated with each other (B=3.39, SE=0.696, t(71)=4.88, p<0.001). BI was not effective at decreasing alcohol use (e.g. no main effect of group, all p values >0.3). Paroxetine decreased social anxiety severity in the face of heavy drinking and decreasing the anxiety was related to a concurrent decrease in coping related drinking. BI was not effective at decreasing drinking or drinking to cope.
