Arrogance in the Workplace: Implications for Mental Health Nurses

Cultures of performativity may contribute to organizational and individual arrogance. Workplace organizations have individuals who at various times will display arrogance, which may manifest in behaviours, such as an exaggerated sense of self-importance, dismissiveness of others, condescending behaviors and an impatient manner. Arrogance is not a flattering label and irrespective of the reason or the position of power, in the context of organizational behaviors, may not be useful and may even be detrimental to the work environment. Thus, it is timely to reflect on the implications of arrogance in the workplace. Advocacy and empowerment can be undermined and relationships adversely impacted, including the achievement of positive consumer outcomes. This paper provides an introduction to arrogance, and then discusses arrogance to promote awareness of the potential consequences of arrogance and its constituent behaviors.     

Do-not-resuscitate orders for critically ill patients in the hospital. How are they used and what is their impact?

We studied compliance with do-not-resuscitate (DNR) orders at a university hospital where a DNR protocol has existed since 1979. Documentation of DNR status in patient progress notes and chart orders increased through 1983. During a 12-month period (March 1983 through April 1984), we studied in detail the medical records of 521 patients who had a cardiopulmonary arrest in the hospital. Seventy-five percent (389 of 521) of these patients were designated DNR. Patients who were designated DNR were significantly more likely to be older, to have malignancy or an abnormal mental status, and to be less likely to have acute myocardial infarction, stroke, or chronic obstructive pulmonary disease than patients in whom resuscitation was attempted. Eighty-six percent of families, but only 22% of patients, were involved in the decision to designate a patient DNR. The decision to designate a patient DNR occurred late in the course of a patient's illness, often when the patient was in coma. For 28% of patients, some form of medical care was withdrawn or withheld after they were designated DNR. These data suggest that use of the DNR protocol requires changes if patients are to participate in the decision not to undergo cardiopulmonary resuscitation.     

Variations in length of stay and outcomes for six medical and surgical conditions in Massachusetts and California

OBJECTIVES.--To determine the extent to which interinstitutional variations in length of stay are explained by differences in patient characteristics and to determine whether patients in hospitals with shorter lengths of stay had worse outcomes. DESIGN.--We reviewed patients' medical records and surveyed patients between 3 and 12 months after hospital discharge using a questionnaire. SETTING.--Six teaching hospitals in California and Massachusetts. PATIENTS.--A cohort of 2484 selected patients who had been hospitalized for acute myocardial infarction or to rule out acute myocardial infarction, coronary artery bypass graft surgery, total hip replacement, cholecystectomy, or transurethral prostatectomy. Between 73% and 84% of the patients with each condition completed a follow-up questionnaire. OUTCOME MEASURES.--In-hospital complications, deaths, length of stay, functional status after hospital discharge, readmission, and patient satisfaction with hospital care were analyzed. RESULTS.--Significant interinstitutional differences in length of stay were noted for all conditions except rule-out acute myocardial infarction. Statistical adjustment for case-mix differences accounted for most of the interinstitutional differences in length of stay for total hip replacement but explained little of the differences in the other conditions. When we controlled statistically for other predictors, length of stay did not have a significant impact on deaths, functional status after hospital discharge, the probability of readmission, or patient satisfaction with hospital care. CONCLUSION.--More research is needed to determine the medical practices that are related to variations in lengths of stay. Routinely available outcome data may help preserve quality in the face of efforts to decrease costs by effecting more standardized practices of care.     

Effects of dehydroepiandrosterone treatment in rats with diet-induced obesity

Previous studies showed that administration of dehydroepiandrosterone (DHEA) to lean and genetically obese Zucker rats reduced body weight. In the present experiments, the effect of DHEA treatment in rats with diet-induced obesity was evaluated. In experiment 1, male Sprague-Dawley rats (300 g) were fed a nonpurified diet (reference group) or a condensed milk-corn oil nonpurified diet [diet-induced obese (DIO) rats] for 7 wk. Then, 0.6% DHEA was included in the food of one-half of the DIO rats (DIO + DHEA rats). After 6 wk, DIO rats weighed 23% more and had greater fat pad weights, cell size and cell number than reference and DIO + DHEA rats. Brown fat mitochondrial respiration was similar in all groups. DIO rats had higher serum cholesterol and triacylglycerol concentrations than reference and DIO + DHEA rats. DIO + DHEA rats had lower serum insulin levels than DIO and reference rats. In experiment 2, male Sprague-Dawley rats (460 g) were fed either the nonpurified diet or the condensed milk diet for 8 wk. Condensed milk-fed rats were then divided into DIO and diet-resistant groups. One-half of the rats in each group were fed 0.6% DHEA for 2 wk. Body weights and serum glucose, insulin, triacylglycerol and triiodothyronine levels were lowered by DHEA treatment in all groups. Liver mitochondrial state 3 respiration rates per gram and per liver and peroxisomal beta-oxidation were higher in DHEA-treated than in control rats. In DIO rats, DHEA treatment appears to interfere with hyperplastic adipose tissue growth. In this strain of rats, DHEA appears to have hypolipidemic and hypoinsulinemic effects.     

Naloxone administration following operant training of sucrose/water discrimination in the rat

 The suppression of food intake observed following naloxone administration has often been ascribed to palatability or taste. Unfortunately, many confounds become apparent when attempts are made to isolate such factors in the investigation of ingestive behaviors. In the present study, rats (two groups) were trained to discriminate either a 10% or 5% sucrose solution from water (0.1 ml). These mildly food deprived subjects (95% of free-feeding weight) were trained to press the appropriate lever in a two-lever operant chamber following sampling of sucrose or water; successful responding was reinforced by delivery of a 45 mg grain food pellet. Following random exposure to reduced sucrose concentrations tested under extinction, a sucrose concentration gradient (1.0, 0.5, 0.1, 0.05, 0.01 and 0.005% sucrose solution) was established for both training groups under IP saline administration. Data collected under IP saline were then compared to those collected following random IP naloxone administration (3.0, 1.0, 0.3 and 0.1 mg/kg). No significant differences were observed between the sucrose concentration gradients obtained under saline and those obtained under naloxone, suggesting that the anorectic effect of naloxone is not primarily determined by discrimination of sweet taste.

Effects of long-term moderate food restriction on growth, serum factors, lipogenic enzymes and adipocyte glucose metabolism in lean and obese Zucker rats

The effects of long-term moderate food restriction were assessed in lean and obese male Zucker rats. A 30% reduction in food intake from 5 to 68 wk of age resulted in parallel lowering of body weight in both lean and obese rats compared to their respective ad libitum-fed control groups. In lean rats, epididymal and retroperitoneal fat pad weights and cell size were lowered by food restriction. In obese rats there was an effect of food restriction on growth of the epididymal pad but not the retroperitoneal pad. Hyperinsulinemia, hyperlipidemia and elevated serum albumin levels, as well as higher activity of lipogenic enzymes, were also not affected by food restriction in the obese rat. In a second experiment, long-term food restriction resulted in greater glucose conversion to CO2 in response to insulin in adipocytes from lean rats but not obese rats compared to their respective control groups. These results indicate that food restriction throughout the first year of life in the obese Zucker rat does not alter the development of hyperplastic obesity and insulin resistance.
