Quantifying Clinical Opportunities at the Navy Trauma Training Center.

INTRODUCTION: Military-Civilian partnerships (MCPs), such as the Navy Trauma Training Center, are an essential tool for training military trauma care providers. Despite Congressional and military leadership support, sparse data exist to quantify participants' clinical opportunities in MCPs. These preliminary data from an ongoing Navy Trauma Training Center outcomes study quantify clinical experiences and compare skill observation to skill performance. MATERIALS AND METHODS: Participants completed clinical logs after each patient encounter to quantify both patients and procedures they were involved with during clinical rotations; they self-reported demographic data. Data analyses included descriptive statistics and chi-square statistics to compare skills observed to skills performed between the first and second half of the 21-day course. RESULTS: A sample of 47 Navy personnel (30 corpsmen, 10 nurses, 3 physician assistants, 4 physicians) completed 551 clinical logs. Most logs (453/551) reflected experiences in the emergency department, where corpsmen and nurses each spent 102.0 hours, and physician assistants and physicians each spent 105.4 hours. Logs completed per participant ranged from 1 to 31, (mean = 8). No professional group was more likely than others to complete the clinical logs. Completion rates varied by cohort, both overall and by clinical role. Of emergency department logs, 39% reflected highest acuity patients, compared with 21% of intensive care unit logs, and 61% of operating room logs. Penetrating trauma was reported on 16.5% of logs. Primary and secondary trauma assessments were the most commonly reported clinical opportunities, followed by obtaining intravenous access and administration of analgesic medications. With few exceptions, logs reflected skill observation versus skill performance, a ratio that did not change over time. CONCLUSION: Prospective real-time data of actual clinical activity is a crucial measure of the success of MCPs. These preliminary data provide a beginning perspective on how these experiences contribute to maintaining a skilled military medical force.

Preliminary Data on Trauma Knowledge, Confidence, and Stress During Navy Trauma Training.

INTRODUCTION: The Navy Trauma Training Center (NTTC) is a military-civilian partnership that provides advanced trauma training for application across the range of military operations while exposing military medical personnel to high-volume and high-acuity trauma. Few published data evaluate the outcomes of military-civilian partnerships, including NTTC. The purpose of this study is to evaluate the knowledge, confidence, and stress of NTTC participants before, at mid-point, and after completion of the program. Participants include corpsmen (HM), nurses (RNs), physician assistants (PAs), and physicians (MDs). MATERIALS AND METHODS: These are preliminary data from an ongoing prospective, observational study with repeated measures. Included are participants that complete NTTC training. Pre-training measures include a demographic questionnaire, trauma knowledge test, Confidence survey, and the Perceived Stress Scale. These same instruments are completed at mid-training and at the conclusion of the NTTC curriculum. Data were analyzed using paired t-tests and linear mixed models. RESULTS: The sample was composed of 83 participants (49 HM, 18 RNs, 4 PAs, and 12 MDs. Knowledge and confidence increased from baseline to post-NTTC for each clinical role (P < .05). Stress for all roles was low and stable over time (P > .05). CONCLUSIONS: These preliminary data suggest that, as expected, trauma-related knowledge and confidence increase significantly with training at NTTC. Stress was low and stable over time. These data from a small sample of participants indicate NTTC training is increasing participants' trauma knowledge and confidence to care for trauma casualties. Continued collection of data in the ongoing study will allow us to determine whether these early findings persist in the overall study sample and may help inform the optimal length of training needed.

Clinical symptoms, signs and tests for identification of impending and current water-loss dehydration in older people.

BACKGROUND: There is evidence that water-loss dehydration is common in older people and associated with many causes of morbidity and mortality. However, it is unclear what clinical symptoms, signs and tests may be used to identify early dehydration in older people, so that support can be mobilised to improve hydration before health and well-being are compromised. OBJECTIVES: To determine the diagnostic accuracy of state (one time), minimally invasive clinical symptoms, signs and tests to be used as screening tests for detecting water-loss dehydration in older people by systematically reviewing studies that have measured a reference standard and at least one index test in people aged 65 years and over. Water-loss dehydration was defined primarily as including everyone with either impending or current water-loss dehydration (including all those with serum osmolality ≥ 295 mOsm/kg as being dehydrated). SEARCH METHODS: Structured search strategies were developed for MEDLINE (OvidSP), EMBASE (OvidSP), CINAHL, LILACS, DARE and HTA databases (The Cochrane Library), and the International Clinical Trials Registry Platform (ICTRP). Reference lists of included studies and identified relevant reviews were checked. Authors of included studies were contacted for details of further studies. SELECTION CRITERIA: Titles and abstracts were scanned and all potentially relevant studies obtained in full text. Inclusion of full text studies was assessed independently in duplicate, and disagreements resolved by a third author. We wrote to authors of all studies that appeared to have collected data on at least one reference standard and at least one index test, and in at least 10 people aged ≥ 65 years, even where no comparative analysis has been published, requesting original dataset so we could create 2 x 2 tables. DATA COLLECTION AND ANALYSIS: Diagnostic accuracy of each test was assessed against the best available reference standard for water-loss dehydration (serum or plasma osmolality cut-off ≥ 295 mOsm/kg, serum osmolarity or weight change) within each study. For each index test study data were presented in forest plots of sensitivity and specificity. The primary target condition was water-loss dehydration (including either impending or current water-loss dehydration). Secondary target conditions were intended as current (> 300 mOsm/kg) and impending (295 to 300 mOsm/kg) water-loss dehydration, but restricted to current dehydration in the final review.We conducted bivariate random-effects meta-analyses (Stata/IC, StataCorp) for index tests where there were at least four studies and study datasets could be pooled to construct sensitivity and specificity summary estimates. We assigned the same approach for index tests with continuous outcome data for each of three pre-specified cut-off points investigated.Pre-set minimum sensitivity of a useful test was 60%, minimum specificity 75%. As pre-specifying three cut-offs for each continuous test may have led to missing a cut-off with useful sensitivity and specificity, we conducted post-hoc exploratory analyses to create receiver operating characteristic (ROC) curves where there appeared some possibility of a useful cut-off missed by the original three. These analyses enabled assessment of which tests may be worth assessing in further research. A further exploratory analysis assessed the value of combining the best two index tests where each had some individual predictive ability. MAIN RESULTS: There were few published studies of the diagnostic accuracy of state (one time), minimally invasive clinical symptoms, signs or tests to be used as screening tests for detecting water-loss dehydration in older people. Therefore, to complete this review we sought, analysed and included raw datasets that included a reference standard and an index test in people aged ≥ 65 years.We included three studies with published diagnostic accuracy data and a further 21 studies provided datasets that we analysed. We assessed 67 tests (at three cut-offs for each continuous outcome) for diagnostic accuracy of water-loss dehydration (primary target condition) and of current dehydration (secondary target condition).Only three tests showed any ability to diagnose water-loss dehydration (including both impending and current water-loss dehydration) as stand-alone tests: expressing fatigue (sensitivity 0.71 (95% CI 0.29 to 0.96), specificity 0.75 (95% CI 0.63 to 0.85), in one study with 71 participants, but two additional studies had lower sensitivity); missing drinks between meals (sensitivity 1.00 (95% CI 0.59 to 1.00), specificity 0.77 (95% CI 0.64 to 0.86), in one study with 71 participants) and BIA resistance at 50 kHz (sensitivities 1.00 (95% CI 0.48 to 1.00) and 0.71 (95% CI 0.44 to 0.90) and specificities of 1.00 (95% CI 0.69 to 1.00) and 0.80 (95% CI 0.28 to 0.99) in 15 and 22 people respectively for two studies, but with sensitivities of 0.54 (95% CI 0.25 to 0.81) and 0.69 (95% CI 0.56 to 0.79) and specificities of 0.50 (95% CI 0.16 to 0.84) and 0.19 (95% CI 0.17 to 0.21) in 21 and 1947 people respectively in two other studies). In post-hoc ROC plots drinks intake, urine osmolality and axillial moisture also showed limited diagnostic accuracy. No test was consistently useful in more than one study.Combining two tests so that an individual both missed some drinks between meals and expressed fatigue was sensitive at 0.71 (95% CI 0.29 to 0.96) and specific at 0.92 (95% CI 0.83 to 0.97).There was sufficient evidence to suggest that several stand-alone tests often used to assess dehydration in older people (including fluid intake, urine specific gravity, urine colour, urine volume, heart rate, dry mouth, feeling thirsty and BIA assessment of intracellular water or extracellular water) are not useful, and should not be relied on individually as ways of assessing presence or absence of dehydration in older people.No tests were found consistently useful in diagnosing current water-loss dehydration. AUTHORS' CONCLUSIONS: There is limited evidence of the diagnostic utility of any individual clinical symptom, sign or test or combination of tests to indicate water-loss dehydration in older people. Individual tests should not be used in this population to indicate dehydration; they miss a high proportion of people with dehydration, and wrongly label those who are adequately hydrated.Promising tests identified by this review need to be further assessed, as do new methods in development. Combining several tests may improve diagnostic accuracy.

Modeling hospital-acquired pressure ulcer prevalence on medical-surgical units: nurse workload, expertise, and clinical processes of care.

OBJECTIVE: This study modeled the predictive power of unit/patient characteristics, nurse workload, nurse expertise, and hospital-acquired pressure ulcer (HAPU) preventive clinical processes of care on unit-level prevalence of HAPUs. DATA SOURCES: Seven hundred and eighty-nine medical-surgical units (215 hospitals) in 2009. STUDY DESIGN: Using unit-level data, HAPUs were modeled with Poisson regression with zero-inflation (due to low prevalence of HAPUs) with significant covariates as predictors. DATA COLLECTION/EXTRACTION METHODS: Hospitals submitted data on NQF endorsed ongoing performance measures to CALNOC registry. PRINCIPAL FINDINGS: Fewer HAPUs were predicted by a combination of unit/patient characteristics (shorter length of stay, fewer patients at-risk, fewer male patients), RN workload (more hours of care, greater patient [bed] turnover), RN expertise (more years of experience, fewer contract staff hours), and processes of care (more risk assessment completed). CONCLUSIONS: Unit/patient characteristics were potent HAPU predictors yet generally are not modifiable. RN workload, nurse expertise, and processes of care (risk assessment/interventions) are significant predictors that can be addressed to reduce HAPU. Support strategies may be needed for units where experienced full-time nurses are not available for HAPU prevention. Further research is warranted to test these finding in the context of higher HAPU prevalence.

Predictors of thirst in intensive care unit patients.

CONTEXT: Thirst is a pervasive, intense, and distressing symptom in intensive care unit (ICU) patients. Although thirst may be avoided and/or treated, scant data are available to help providers identify patients most in need. OBJECTIVES: This study was designed to identify predictors of the presence, intensity, and distress of thirst in ICU patients. METHODS: This descriptive cross-sectional study enrolled 353 patients from three ICUs (medical-surgical, cardiac, and neurological). To measure outcomes, patients were asked to report the presence of thirst (yes/no) and, if present, to rate its intensity and distress on zero to 10 numeric rating scales (10=worst). Predictor variables were demographic (e.g., age), treatment-related (e.g., opioids), and biological (e.g., total body water). Data were analyzed with logistic regression and truncated regression with alpha preset at 0.05. RESULTS: Thirst presence was predicted by high opioid doses (≥ 50 mg), high furosemide doses (>60 mg), selective serotonin reuptake inhibitors, and low ionized calcium. Thirst intensity was predicted by patients not receiving oral fluid and having a gastrointestinal (GI) diagnosis. Thirst distress was predicted by mechanical ventilation, negative fluid balance, antihypertensive medications, and a GI or "other" diagnosis. CONCLUSION: Thirst presence was predicted by selected medications (e.g., opioids). Thirst intensity and/or thirst distress were predicted by other treatments (e.g., mechanical ventilation) and medical diagnoses (e.g., GI). This is one of the first studies describing predictors of the multidimensional characteristics of thirst. Clinicians can use these data to target ICU patients whose thirst might warrant treatment.

Hospital staff registered nurses' perception of horizontal violence, peer relationships, and the quality and safety of patient care.

OBJECTIVE: To test hypotheses from a horizontal violence and quality and safety of patient care model: horizontal violence (negative behavior among peers) is inversely related to peer relations, quality of care and it is positively related to errors and adverse events. Additionally, the association between horizontal violence, peer relations, quality of care, errors and adverse events, and nurse and work characteristics were determined. PARTICIPANTS: A random sample (n= 175) of hospital staff Registered Nurses working in California. METHODS: Nurses participated via survey. Bivariate and multivariate analyses tested the study hypotheses. RESULTS: Hypotheses were supported. Horizontal violence was inversely related to peer relations and quality of care, and positively related to errors and adverse events. Including peer relations in the analyses altered the relationship between horizontal violence and quality of care but not between horizontal violence, errors and adverse events. Nurse and hospital characteristics were not related to other variables. Clinical area contributed significantly in predicting the quality of care, errors and adverse events but not peer relationships. CONCLUSIONS: Horizontal violence affects peer relationships and the quality and safety of patient care as perceived by participating nurses. Supportive peer relationships are important to mitigate the impact of horizontal violence on quality of care.

A randomized clinical trial of an intervention to relieve thirst and dry mouth in intensive care unit patients.

PURPOSE: To test an intervention bundle for thirst intensity, thirst distress, and dry mouth, which are among the most pervasive, intense, distressful, unrecognized, and undertreated symptoms in ICU patients, but for which data-based interventions are lacking. METHODS: This was a single-blinded randomized clinical trial in three ICUs in a tertiary medical center in urban California. A total of 252 cognitively intact patients reporting thirst intensity (TI) and/or thirst distress (TD) scores ≥3 on 0-10 numeric rating scales (NRS) were randomized to intervention or usual care groups. A research team nurse (RTN#1) obtained patients' pre-procedure TI and TD scores and reports of dry mouth. She then administered a thirst bundle to the intervention group: oral swab wipes, sterile ice-cold water sprays, and a lip moisturizer, or observed patients in the usual care group. RTN#2, blinded to group assignment, obtained post-procedure TI and TD scores. Up to six sessions per patient were conducted across 2 days. RESULTS: Multilevel linear regression determined that the average decreases in TI and TD scores from pre-procedure to post-procedure were significantly greater in the intervention group (2.3 and 1.8 NRS points, respectively) versus the usual care group (0.6 and 0.4 points, respectively) (p < 0.05). The usual care group was 1.9 times more likely than the intervention group to report dry mouth for each additional session on day 1. CONCLUSION: This simple, inexpensive thirst bundle significantly decreased ICU patients' thirst and dry mouth and can be considered a practice intervention for patients experiencing thirst.

A prospective window into medical device-related pressure ulcers in intensive care.

The aim of this study was to determine the prevalence, severity, location, aetiology, treatment and healing of medical device-related pressure ulcers (PUs) in intensive care patients for up to 7 days. A prospective repeated measures study design was used. Patients in six intensive care units of two major medical centres, one each in Australia and the USA, were screened 1 day per month for 6 months. Those with device-related ulcers were followed daily for up to 7 days. The outcome measures were device-related ulcer prevalence, pain, infection, treatment and healing. Fifteen of 483 patients had device-related ulcers and 9 of 15 with 11 ulcers were followed beyond screening. Their mean age was 60·5 years, and most were men, overweight and at increased risk of PU. Endotracheal (ET) and nasogastric (NG) tubes were the cause of most device-related ulcers. Repositioning was the most frequent treatment. Four of 11 ulcers healed within the 7-day observation period. In conclusion, device-related ulcer prevalence was 3·1%, similar to that reported in the limited literature available, indicating an ongoing problem. Systematic assessment and repositioning of devices are the mainstays of care. We recommend continued prevalence determination and that nurses remain vigilant to prevent device-related ulcers, especially in patients with NG and ET tubes.

Quench the thirst: lessons from clinical thirst trials.

Thirst, as a symptom, has long been considered the most prevalent clinical complaint patients voice in healthcare settings. Yet, rarely have researchers examined thirst by its correlation with physiologic factors. This review was undertaken to examine the relationships between thirst ratings and factors mediating its primary physiologic correlates: plasma osmolality (pOsm) and arginine vasopressin peptide (AVP). A literature search was undertaken to identify clinical studies in human subjects that investigated the relationship of thirst to specific physiologic thirst-related correlates and associated thirst mediators. Thirst was induced in 17 selected clinical studies by hyperosmolar infusion, through water deprivation or exercise weight-loss regimens. Positive linear relationships between the subjects' thirst ratings and rising serum pOsm levels confirmed the presence of intact osmotic thirst drives. However, there were significant variations in normal compensatory rises in AVP levels that followed the rises in plasma osmolality after the subjects were exposed to cold, physical pre-conditioning and water immersion tests. Notably, older adults in the studies reported diminished thirst ratings. Weak correlations suggest that angiotensin II may play only a minor role in thirst mediation. Atrial natriuretic hormone's inhibitory effect on thirst was inconsistent. Findings indicated that older adults are at higher risk for profound dehydration due to sensory deficits along with failure to correct volume losses. The thirst trials results support the close correlation between serum pOsm values and patients' thirst ratings, with the exception of the older adult.

Dyspnea coping strategies in Korean immigrants with asthma or chronic obstructive pulmonary disease.

PURPOSE: Patients with lung disease develop coping strategies to relieve dyspnea. The coping strategies of Korean immigrants, however, are poorly understood. The purpose of this study was to describe the strategies that Korean immigrants with asthma or chronic obstructive pulmonary disease (COPD) use to cope with dyspnea and to compare similarities and differences in coping strategies between the two conditions. DESIGN: Outpatients with asthma (n = 25) or COPD (n = 48) participated in a cross-sectional descriptive study. METHOD: Open-ended questions and a structured instrument were used to describe coping strategies for dyspnea. Descriptive and inferential statistics were used to analyze the data. RESULTS: The most prevalent strategy was "I keep still or rest." Korean immigrants also used traditional therapies to manage dyspnea. CONCLUSIONS: Although the coping strategies of Korean immigrants were similar to those of other ethnic groups, they incorporated elements of Asian medical practice and herbs. This finding enables health care providers to better understand Korean immigrants' efforts to overcome dyspnea and to guide their patients' approach to coping.

A biopsychosocial-spiritual model of chronic pain in adults with sickle cell disease.

Chronic pain in adults with sickle cell disease (SCD) is a complex multidimensional experience that includes biologic, psychologic, sociologic, and spiritual factors. To date, three models of pain associated with SCD (i.e., biomedical model, biopsychosocial model for SCD pain, and Health Beliefs Model) have been published. The biopsychosocial multidimensional approach to chronic pain developed by Turk and Gatchel is a widely used model of chronic pain. However, this model has not been applied to chronic pain associated with SCD. In addition, a spiritual/religious dimension is not included in this model. Because spirituality/religion is central to persons affected by SCD, that dimension needs to be added to any model of chronic pain in adults with SCD. In fact, data from one study suggest that spirituality/religiosity is associated with decreased pain intensity in adults with chronic pain from SCD. A biopsychosocial-spiritual model is proposed for adults with chronic pain from SCD, because it embraces the whole person. This model includes the biologic, psychologic, sociologic, and spiritual factors relevant to adults with SCD based on past and current research. The purpose of this paper is to describe an adaptation of Turk and Gatchel's model of chronic pain for adults with SCD and to summarize research findings that support each component of the revised model (i.e., biologic, psychologic, sociologic, spiritual). The paper concludes with a discussion of implications for the use of this model in research.

Enteral nutritional intake in adult korean intensive care patients.

BACKGROUND: Nutritional support is important for maximizing clinical outcomes in critically ill patients, but enteral nutritional intake is often inadequate. OBJECTIVE: To assess the nutritional intake of energy and protein during the first 4 days after initiation of enteral feeding and to examine the relationship between intake and interruptions of enteral feeding in Korean patients in intensive care. METHODS: A cohort of 34 critically ill adults who had a primary medical diagnosis and received bolus enteral feeding were studied prospectively. Energy and protein requirements were determined by using the Harris-Benedict equation and the American Dietetic Association equation. Energy and protein intake prescribed and received and the reasons for and lengths of feeding interruptions were recorded for 4 consecutive days immediately after enteral feeding began. RESULTS: Although the differences between requirements and intakes of energy and protein decreased significantly, patients did not receive required energy and protein intake during the 4 days of the study. Energy intake prescribed was consistently less than required on each of the 4 days. Enteral nutrition was withheld for a mean of 6 hours per patient for the 4 days. Prolonged feeding interruptions due to gastrointestinal intolerance (r= -0.874; P < .001) and procedures (r= -0.839; P = .005) were negatively associated with the percentage of prescribed energy received. CONCLUSIONS: Enteral nutritional intake was insufficient in bolus-fed Korean intensive care patients because of prolonged feeding interruptions and underprescription of enteral nutrition. Feeding interruptions due to gastrointestinal intolerance and procedures were the main contributors to inadequate energy intake.

Knowledge and beliefs about smoking and goals for smoking cessation in hospitalized men with cardiovascular disease.

OBJECTIVES: To describe perceptions of smoking in men hospitalized with cardiovascular disease (CVD). BACKGROUND: Smoking is a major risk factor and associated with the high prevalence of CVD in Jordan. METHODS: The study design was cross-sectional with a convenience sample. A structured interview was conducted in 112 men who were hospitalized with CVD. RESULTS: The study showed that 91% of men hospitalized with CVD smoked daily. The majority (83%) had attempted to quit smoking in the past without help from others, and intended to quit in the future using the same previously unsuccessful method. They were unaware of the hazards of smoking such as stroke; or the long term health benefits of quitting smoking. Logistic regressions showed that men were more confident in quitting smoking if they had a high income (OR: 7.7; 95% CI: 2.7, 22.3), longer hospitalizations (OR: 2.6; 95% CI: 1.3, 5.3), or were hospitalized in acute cardiac settings (OR: 3.9; 95% CI: 1.2, 12.7), and admitted with a diagnosis of MI or angina (OR: 3.0; 95% CI: 1.1, 8.3). CONCLUSION: Assessment of smoking status with smoking cessation counseling is paramount in hospitalized men with CVD who smoke.

Eliminating hospital-acquired pressure ulcers: within our reach.

Hospital-acquired pressure ulcers (HAPUs) are a serious nosocomial problem that has been viewed as a ubiquitous consequence of immobility. This article provides data from the Collaborative Alliance for Nursing Outcomes (CALNOC) that shows a significant reduction in HAPUs in adults from 78 acute care hospitals over 8 years (2003-2010).

Why patients in critical care do not receive adequate enteral nutrition? A review of the literature.

Enteral nutrition is frequently used to provide nutrients for critically ill patients. However, only about half of critically ill enterally fed patients receive their energy requirements. Underfeeding is associated with detrimental clinical outcomes including infection, pressure ulcers, impaired wound healing, prolonged hospital stays, and increased morbidity and mortality. This literature review was conducted to identify major barriers to adequate enteral nutrition intake in critically ill adults and to identify gaps in the research literature. Studies (n = 30) reviewed addressed adult patients in critical care, published since 1999, and written in English. Findings showed that factors that explain inadequate enteral nutritional intake include delayed initiation of enteral nutrition and slow advancement of infusion rate, underprescription, incomplete delivery of prescribed nutrition, and frequent interruption of enteral nutrition. Frequent interruption was caused by diagnostic tests, surgical procedures, gastrointestinal intolerance, feeding tube problems, and routine nursing procedures. There are no standardized protocols that address these barriers to receiving adequate enteral intake. Such protocols must be developed, implemented, and tested to address undernutrition and mitigate the negative consequences of inadequate enteral intake.

Horizontal violence among hospital staff nurses related to oppressed self or oppressed group.

Horizontal violence among nurses is recognized as a major problem in hospitals; however, the origins and effects on patient care have not been studied. This study described the incidence of horizontal violence among hospital staff RNs and tested 2 hypotheses about the social origins of this behavior. A random sample of 175 hospital staff RNs drawn from the California Board of Registered Nursing's mailing list was surveyed. Horizontal violence was reported by 21.1% (n = 37) of participating nurses. Hypotheses were supported. Findings suggested (a) a positive relationship between beliefs consistent with an oppressed self and horizontal violence (r = .434, P < .05) and (b) a positive relationship between beliefs consistent with those of an oppressed group and horizontal violence (r = .453, P < .05). A change in the oppressive social structure of hospitals may be needed to truly address horizontal violence in the best interest of the quality and safety of patient care.

Adequacy of early enteral nutrition in adult patients in the intensive care unit.

AIMS AND OBJECTIVES: To evaluate the adequacy of energy and protein intake of patients in a Korean intensive care unit in the first four days after initiation of enteral feeding and to investigate the factors that had impact on adequate intake. BACKGROUND: Underfeeding is a common problem for patients hospitalised in the intensive care unit and is associated with severe negative consequences, including increased morbidity and mortality. DESIGN: A prospective, cohort study was conducted in a medical intensive care unit of a university hospital in Korea. METHODS: A total of 34 adult patients who had a primary medical diagnosis and who had received bolus enteral nutrition for the first four days after initiation of enteral nutrition were enrolled in this study. The data on prescription and intake of energy and protein, feeding method and feeding interruption were recorded during the first four days after enteral feeding initiation. Underfeeding was defined as the intake <90% of required energy and protein. RESULTS: Most patients (62%) received insufficient energy, although some (29%) received adequate energy. More than half of patients (56%) had insufficient protein intake during the first four days after enteral feeding was initiated. Logistic regression analysis showed that the factors associated with underfeeding of energy were early initiation of enteral nutrition, under-prescription of energy and prolonged interruption of prescribed enteral nutrition. CONCLUSION: Underfeeding is frequent in Korean critically ill patients owing to early initiation, under-prescription and prolonged interruption of enteral feeding. RELEVANCE TO CLINICAL PRACTICE: Interventions need to be developed and tested that address early initiation, under-prescription and prolonged interruption of enteral nutrition. Findings from this study are important as they form the foundation for the development of evidence-based care that is badly needed to eliminate underfeeding in this large vulnerable Korean intensive care unit population.

Family caregiving in pulmonary arterial hypertension.

BACKGROUND: Pulmonary arterial hypertension (PAH) is a devastating disease that places a significant burden on patients and their families. However, family caregiving, to the best of our knowledge, has never been described in this population. This study sought to describe depressive symptoms, types of performed care tasks, social support, and the impact of caregiving among family caregivers of patients with PAH. METHODS AND RESULTS: Data were obtained from 35 dyads of patients with PAH (mean age, 51 years; 63% were female; 54% had World Health Organization functional class III symptoms) and their family caregivers (mean age, 52 years; 60% were female; 68% were spouses). Five caregivers (14%) were identified as manifesting moderate to severe depressive symptoms. The majority of caregivers reported that their daily activities were centered around caregiving responsibilities. More than 85% of caregivers were involved in managing care for the patient, and more than half helped the patient with self-management activities. The level of caregivers' perceived social support was low, especially for emotional and informational support. Lower levels of social support were significantly associated with more severe depressive symptoms in caregivers (r = -.50, P = .002). CONCLUSION: Caregivers of patients with PAH play a significant role in patients' medical care and self-management, yet they lack sufficient emotional support or information to meet the demands of caregiving. These findings underscore the importance of supporting family caregivers of patients with PAH.

Effect of culturally tailored diabetes education in ethnic minorities with type 2 diabetes: a meta-analysis.

BACKGROUND: Diabetes is a major cause of cardiovascular morbidity and mortality. Ethnic minorities experience a disproportionate burden of diabetes; however, few studies have critically analyzed the effectiveness of a culturally tailored diabetes intervention for these minorities. OBJECTIVE: The aim of this study was to evaluate the effectiveness of a culturally tailored diabetes educational intervention (CTDEI) on glycemic control in ethnic minorities with type 2 diabetes. METHOD: We searched databases within PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Education Resources Information Center (ERIC), PsycINFO, and ProQuest for randomized controlled trials (RCTs). We performed a meta-analysis for the effect of diabetes educational intervention on glycemic control using glycosylated hemoglobin (HbA(1c)) value in ethnic minority groups with type 2 diabetes. We calculated the effect size (ES) with HbA(1c) change from baseline to follow-up between control and treatment groups. RESULTS: The 12 studies yielded 1495 participants with a mean age of 63.6 years and a mean of 68% female participants. Most studies (84%) used either group education sessions or a combination of group sessions and individual patient counseling. The duration of interventions ranged from 1 session to 12 months. The pooled ES of glycemic control in RCTs with CTDEI was -0.29 (95% confidence interval, -0.46 to -0.13) at last follow-up, indicating that ethnic minorities benefit more from CTDEI when compared with the usual care. The effect of intervention was greatest and significant when HbA(1c) level was measured at 6 months (ES, -0.41; 95% confidence interval, -0.61 to -0.21). The ES also differed by each participant's baseline HbA1c level, with lower baseline levels associated with higher ESs. CONCLUSIONS: Based on this meta-analysis, CTDEI is effective for improving glycemic control among ethnic minorities. The magnitude of effect varies based on the settings of intervention, baseline HbA1c level, and time of HbA1c measurement. More rigorous RCTs that examine tailored diabetes education, ethnically matched educators, and more diverse ethnic minority groups are needed to reduce health disparities in diabetes care.

Symptoms and functional performance in Korean immigrants with asthma or chronic obstructive pulmonary disease.

OBJECTIVES: People with chronic obstructive lung diseases often experience a variety of symptoms. Few studies, however, have described these symptoms in detail. This study sought to examine concurrent symptoms, symptom clusters, and the effects of symptoms on functioning in Korean immigrants with asthma or chronic obstructive pulmonary disease (COPD). METHODS: Outpatients with asthma or COPD participated in this cross-sectional, correlational study. Symptoms, dyspnea, mood, and functional performance were assessed with questionnaires. Descriptive and inferential statistics were used to analyze the data. RESULTS: The most frequently reported symptom was shortness of breath. Three factors emerged from 16 symptoms. Age, mean severity score of 7 symptoms, working status, level of acculturation, and level of education explained significant variance in functional performance. CONCLUSION: The symptom cluster, consisting of 7 symptoms, showed the greatest effect on levels of functioning, which emphasizes the importance of assessment for coexisting symptoms in populations with these diseases.
