Measuring psychological insulin resistance: barriers to insulin use.

PURPOSE: The purpose of this study is to explore the attitudes that contribute to psychological insulin resistance (PIR) in insulin-naive patients with type 2 diabetes and to identify predictors of PIR. METHODS: A prospective study using 2 self-report surveys and incorporating demographic and health variables was conducted to determine the prevalence of PIR among a sample of 100 adult, insulin-naive patients with type 2 diabetes at an outpatient diabetes center in a university-affiliated teaching hospital. RESULTS: Thirty-three percent of patients with type 2 diabetes were unwilling to take insulin. The most commonly expressed negative attitudes were concern regarding hypoglycemia, permanent need for insulin therapy, less flexibility, and feelings of failure. Less than 40% expressed fear of self-injection or thought that injections were painful. However, compared with willing subjects, unwilling subjects were more likely to fear injections and thought injections would be painful, life would be less flexible, and taking insulin meant health would deteriorate (P< .005 for all comparisons). Poorer general health and higher depression scores also correlated with PIR. CONCLUSIONS: The results of the surveys, which were generally consistent, identified several remediable misconceptions regarding insulin therapy and suggest targets for educational interventions.

Peripheral arterial sheath removal program: a performance improvement initiative.

The increasing number of endovascular procedures by both cardiologists and vascular surgeons strain available resources, such as recovery space, creating delays in the throughput of patients. The use of alternative settings, personnel, and approaches to postprocedural care has been proposed to maximize the number of procedures that can be done with existing procedure rooms. However, a key question remains about whether this can be done safely and achieve good patient outcomes. A performance improvement project was conducted to evaluate the safety and effectiveness of shifting postprocedural care and removal of intraarterial sheaths by the staff in the cardiac catheterization laboratory to specially trained acute care nurses on an inpatient vascular surgical unit. The purpose of this project was to develop a performance improvement project that included administrative, educational, and clinical components and to evaluate effects on key patient outcomes, prospectively, over 15 months.

The cost and efficacy of two wound treatments.

Using the physiology of moist wound healing as the framework, this nonexperimental, retrospective chart review compared the rate of wound healing and cost of wound care associated with wet-to-dry normal saline gauze dressings to the rate of wound healing and cost of wound care associated with amorphous hydrogel dressings for patients with infrainguinal arterial disease and diabetes. These patients were discharged from the hospital to home care for management of perioperative arterial surgical wound dehiscence and nonhealing ulcerations. The sample included 25 patients who used wet-to-dry normal saline gauze dressings and 25 patients who used amorphous hydrogel dressings. Repeated measures of analysis of covariance revealed a similar rate of wound healing in the two groups. The overall cost of wound care was significantly higher (P = .006) for patients in the normal saline group, with a higher number and cost of home nursing visits. The cost of supplies was not significantly different between groups, although amorphous hydrogel dressings cost an average of dollar 50 more than wet-to-dry normal saline gauze dressings. The two treatments are equally efficacious in promoting wound healing, but amorphous hydrogel dressings are significantly more cost effective and, thus, a better value for the home care dollar.

Promoting research utilization using a conceptual framework.

Since the early 1990s, evidence-based practice has gained momentum, but barriers persist between knowledge development and application in practice. The Massachusetts General Hospital re-engineered the Nursing Research Committee as one vehicle for promoting research-based practice. Using the Promoting Action on Research Implementation in Health Services framework, the mission and methods (context) to advance research-based practice are explicated. Characteristics of the membership, leadership, and practice environment that facilitate research utilization are delineated.
