Reducing Hydration-Linked Events in Nursing Home Residents

The authors used a quasi-experimental treatment and control group design with 49 participants from four nursing homes to test the effectiveness of an 8-week hydration intervention in reducing hydration-linked events (HLEs). A Kaplan Meier survival curve with log rank test was calculated to determine incidence and time to occurrence of a HLE. Incidence of and time to a HLE did not differ between the treatment and control groups over an 8-week period (p >.05). However, treatment group participants were found to be more frail, more cognitively impaired, and more at risk for acute confusion than the control group participants. Although there were no statistically significant differences between the groups, it is clinically significant that the frailer, more at-risk participants in the treatment group had a lower incidence of HLEs.

Violence Against Women: The Phenomenon of Workplace Violence Against Nurses

Registered nurses have been the recipients of an alarming increase in workplace violence (WPV). Emergency and psychiatric nurses have been found to be the most vulnerable and yet few solid reporting procedures exist to fully account for a true number of incidents. Further compounding the problem is the lack of a standard definition of violence to guide reporting procedures, interventions, legislation, and research. While there are certain risk factors that not only predispose the nurse and the patient to WPV, research continues to attempt to parse out which risk factors are the key determinants of WPV and also which interventions prove to be significant in reducing WPV. The nursing shortage is expected only to increase; recruitment and retention of qualified staff members may be deterred by WPV. This necessitates focused research on the phenomenon of workplace violence in health care.

Use of a urine color chart to monitor hydration status in nursing home residents

To determine whether urine color, as measured by a color chart, might be a valid indicator of hydration status in frail nursing home residents, this study tested the associations between urine color and urine specific gravity. This is a descriptive correlational study set in seven nursing homes in eastern Iowa. Ninety-eight nursing home residents 65 years of age participated. Exclusion criteria for the study included: unstable congestive heart failure or diabetes, documented renal disease, hyponatremia (serum sodium < 135 meq/L), terminal illness, acutely confused/delirious or urinary tract infection at baseline, and gastrostomy-tube dependence. Weekly urine specimens were collected. Ucol was measured first, using a urine color chart. Usg was determined using the Chemstrip Mini UA Urine Analyzer. Week-by-week Spearman rank order correlations between urine color and specific gravity for the total sample (n = 98) ranged from rs = 0.3 - 0.7, p < .01; the PROC mixed model was significant, p < .01. In subgroup analyses (n = 78), all females (rs = 0.67, p = .01) and both males (rs = 0.53, p = .01) and females (rs = 0.72, p = .01) with adequate renal function (Cockcroft-Gault estimated creatinine clearance [CrCl] values of 50 ml/min) had significant associations between average urine color and average Usg. Females with mild renal impairment (CrCl between 30 and 50 ml/min) also had significant associations between Ucol and Usg (rs = .64, p < .01). Ucol averaged over several individual readings offers another tool in assessing hydration status in Caucasian nursing home residents with ade quate renal function measures by estimated CrCl values.

Barriers and facilitators in nursing home intervention research

Conducting intervention research in nursing home (NH) settings is particularly challenging because of the advanced age and frailty of the participants and the characteristics of the setting itself. The purpose of this project was to better understand the barriers and facilitators to the research process in NHs. Three primary data sources were used: investigator field notes, guided interviews with the research team and NH staff members, and research assistant (RA) e-mail communications. Data were analyzed using qualitative content and matrix analytic techniques. Barriers to the research process were largely congruent with previously identified NH staff characteristics, such as lack of communication between NH staff and the research team, ineffective nursing leadership, decreased staff-to-resident ratios, and high turnover of NH staff. Research facilitators emerged in two overlapping areas, intraresearch team issues such as the flexibility and compatibility of the RAs, effective NH staff-to-research team communication, and the presence of an effective nurse leader in the NH.

Calming aggressive reactions--a preventive program

1. Aggressive behavior of nursing home residents towards caregivers, specifically nurse aides, is increasingly a problem in nursing homes. 2. The C.A.R.E. Program was developed to educate nursing personnel about prevention of aggressive incidents through early identification of residents most likely to become abusive. 3. The C.A.R.E. Program utilizes didactic presentation, role playing, sharing experiences, and group support as teaching strategies. 4. A major implication for professional nurses is to assume responsibility for identifying elders at risk for aggression and to provide the nursing team with the training to best care for these residents.

Monitoring Hydration Status in Elderly Veterans

Dehydration is a common water and electrolyte disorder in long-term care residents. Practical methods to detect and monitor dehydration are needed. This study determined whether urine color measured by a urine color chart reflects hydration status. The study employed a repeated measures design with two observations during a 10-hour period. Urine color was compared to the criterion standard of urine specific gravity and osmolality. The sample included 89 participants from two Veterans’ Affairs facilities. Urine color was graded on an eight-level color chart. Urine specific gravity and osmolality, serum sodium and osmolality, hematocrit, blood urea nitrogen (BUN), and creatinine were measured using standard laboratory procedures. Significant positive associations existed between urine color and both urine specific gravity and urine osmolality and between urine osmolality and serum sodium and the blood urea nitrogen to creatinine ratio. Although further testing is needed, the color chart has potential as a low-cost technology to monitor dehydration.

Acute confusion/delirium protocol

This abbreviated version of the Acute Confusion/Delirium Research-Based protocol provides clinical guidelines for the assessment and management of acute confusion/delirium in the elderly individual. A screening and ongoing surveillance program that is based on identified risk factors is recommended to prevent or minimize episodes of acute confusion in this age group. This protocol is part of a series of protocols developed to help clinicians use the best evidence available in the care of older adults.

Hypertension prevalence, awareness, and control in Arab countries: a systematic review.

One billion of the worlds population has hypertension, resulting in four million deaths per year. Data on the prevalence of hypertension in the Arab world are very limited. This review summarizes existing knowledge regarding prevalence, awareness, and control of hypertension in Arab countries. The PubMed, Cochrane Library, Scopus, and CINAHL databases were searched for publications on HTN among Arab people from 1980 to January 2011. Only 13 studies were identified in the literature from 10 Arab countries. The overall estimated prevalence of hypertension was 29.5% (n = 45 379), which indicates a higher prevalence of hypertension among Arabs compared to people from the USA (28%) and sub-Saharan African (27.6%). Awareness of hypertension was reported for 46% of the studies and varied from 18% (Jordan) to 79.8% (Syria). The control rate varied from 56% (Tunisia) to 92% (Egypt and Syria). The prevalence of hypertension was found to increase with age, occurring more frequently in Arab women.

Hydration and Acute Confusion in Long-Term Care Residents

Although it is generally appropriate for a healthy adult to consume 2000 to 2500 ml per day, the literature does not address evaluating any standard. The objective here was to develop a weight-based hydration management intervention and evaluate the impact of this on the incidence of acute confusion (AC) using an N = 98. The intervention consisted of a fluid intake goal based on 100 ml per kg for the first 10 kg, 50ml/kg for the next 10 kg, and 15 ml for the remaining body weight. The treatment group received instruction and assistance on the fluid goal and the control group received routine care. Measurements included serum electrolytes, bioimpedance analysis, urinalysis, Mini-Mental State Exam, and the NEECHAM. There was no difference in the incidence of AC between treatment and controls, but those individuals with ≥ 90% compliance demonstrated higher ECF volumes and also lower urine leukocyte counts.

Development and evaluation of a safe and effective sugar-free herbal lollipop that kills cavity-causing bacteria.

Dental caries (tooth decay) is caused by a specific group of cariogenic bacteria, like Streptococcus mutans, which convert dietary sugars into acids that dissolve the mineral in tooth structure. Killing cariogenic bacteria is an effective way to control or prevent tooth decay. In a previous study, we discovered a novel compound (Glycyrrhizol A), from the extraction of licorice roots, with strong antimicrobial activity against cariogenic bacteria. In the current study, we developed a method to produce these specific herbal extracts in large quantities, and then used these extracts to develop a sugar‐free lollipop that effectively kills cariogenic bacteria like Streptococcus mutans. Further studies showed that these sugar‐free lollipops are safe and their antimicrobial activity is stable. Two pilot human studies indicate that a brief application of these lollipops (twice a day for ten days) led to a marked reduction of cariogenic bacteria in oral cavity among most human subjects tested. This herbal lollipop could be a novel tool to promote oral health through functional foods.
