Measuring outcomes in health care have become mandatory as regulatory agencies, institutional guidelines, employers, and consumer groups advocate for quality health care focusing on improving patient outcomes. System-level quality departments often provide a framework for performance improvement (PI) that supports the organizational PI plan. However, nurses must learn to lead and be actively involved in projects in the radiology department to ensure key performance indicators are developed with on-the-ground quality management to improve patient outcomes, system performance, and professional development. This article explores such efforts at a large women’s specialty hospital in the Southern United States. 相似文献

Background and ObjectiveVaccine uptake during pregnancy remains low. Our objectives were to describe 1) development and adaptation of a clinician communication training intervention for maternal immunizations and 2) obstetrics and gynecology (ob-gyn) clinician and staff perspectives on the intervention and fit for the prenatal care context.MethodsDesign of the Motivational Interviewing for Maternal Immunizations (MI4MI) intervention was based on similar communication training interventions for pediatric settings and included presumptive initiation of vaccine recommendations (“You’re due for two vaccines today”) combined with motivational interviewing (MI) for hesitant patients. Interviews and focus group discussions were conducted with ob-gyn clinicians and staff in five Colorado clinics including settings with obstetric physicians, certified nurse midwives (CNMs), and clinician-trainees. Participants were asked about adapting training to the ob-gyn setting and their implementation experiences. Feedback was incorporated through iterative changes to training components.ResultsInterview and focus group discussion results from participants before (n = 3), during (n = 11) and after (n = 25) implementation guided intervention development and adaptation. Three virtual, asynchronous training components were created: a video and two interactive modules. This virtual format was favored due to challenges attending group meetings; however, participants noted opportunities to practice skills through role-play were lacking. Training modules were adapted to include common challenging vaccine conversations and live-action videos. Participants liked interactive training components and use of adult learning strategies. Some participants initially resisted the presumptive approach but later found it useful after applying it in their practices. Overall, participants reported that MI4MI training fit well with the prenatal context and recommended more inclusion of non-clinician staff.ConclusionsMI4MI training was viewed as relevant and useful for ob-gyn clinicians and staff. Suggestions included making training more interactive, and including more complex scenarios and non-clinician staff. 相似文献

IntroductionA sexual assault nurse examiner role exemplifies the high-stress and highly emotional patient interactions that are often associated with burnout. The purpose of this study was to examine the frequency of burnout among sexual assault nurse examiners in North Carolina.MethodsThis cross-sectional study was an anonymous survey of practicing sexual assault nurse examiners within North Carolina using the Maslach Burnout Inventory and additional demographics. Results were analyzed with odds ratios, confidence intervals, Fisher exact, chi-square, and Kruskal Wallis tests as appropriate.ResultsAmong 95 respondents, burnout was more frequent in sexual assault nurse examiners who stopped both emergency and nurse examiner work (55.6%, odds ratio 4.41, 95% confidence interval 1.07-18.06) and in dual function nurses (both emergency and nurse examiner work, 35.7%, odds ratio 2.71, 95% confidence interval 1.04-7.06). Sexual assault nurse examiners who had a high percentage of pediatric cases (above the median of 40%) were more likely to meet burnout thresholds for emotional exhaustion scores > 26 (48.78% vs 25.93%, χ2 = 5.30, P = .02) and more likely to meet burnout thresholds for depersonalization scores > 9 (48.78% vs 24.07%, χ2 = 6.28, P = .01).DiscussionHigher frequency of burnout threshold criteria was found in those people who worked concurrently as a sexual assault nurse examiner and an emergency nurse and in those who had retired from both specialties. We also found that sexual assault nurse examiners with a higher case mix of pediatric cases had higher emotional exhaustion scores and higher depersonalization scores. 相似文献

The coronavirus disease 2019 pandemic disrupted health care, requiring organizational leaders to act quickly to manage the health-related concerns of individuals and communities. The ability to offer a variety of digitally enabled telehealth services with 24/7 access to nurse practitioners and physician assistants allowed us to care for patients in their homes. It reduced the spread of the virus, protected our employees from further disease spread, and provided early interventions to those in need. The roles of nurse practitioner leaders, the enacted strategies, and patient outcomes demonstrate the impact of an innovative digital care delivery model on care across the continuum. 相似文献

PurposeAromatase inhibitors (AIs) limit the synthesis of oestrogen in peripheral tissues thus lowering levels of oestrogen. The primary aim was to evaluate whether women treated with AIs have altered dry eye symptoms and signs. A sub-aim was to investigate whether symptoms of dry eye in postmenopausal women were associated with symptoms of non-eye pain, ocular pain and self-rated pain perception.MethodsThis cross-sectional, observational, single visit study recruited 56 postmenopausal women (mean age 64.1 + 7.9 years) and 52 undergoing AI treatment (mean age 66.6 + 9.0). Ocular symptoms (OSDI, MGD14) and pain questionnaires (PSQ, OPAS) were administered and signs of dry eye and meibomian gland dysfunction were evaluated.ResultsAlmost half of each group reported dry eye symptoms, defined as OSDI>12 (48% control, 46% AI). The PSQ score was significantly higher in the AI group (p = 0.04). Neither frequency or severity of dry eye (or MGD) symptoms scores were significantly different between groups. In the AI group, meibomian gland expressibility score was worse (p = 0.003); there were no differences in any other signs. Higher OSDI scores were associated with higher OPAS eye-pain scores (r = 0.49, p < 0.001), but not OPAS non-eye pain (r = 0.09, p = 0.35). Pain perception (PSQ) showed a moderate positive association with OPAS eye-pain (r = 0.30, p = 0.003).ConclusionsIn this study elevated ocular symptoms were observed in both the AI treated and the untreated groups, with no difference between the groups. Women undergoing AI treatment for early stage breast cancer had worse meibum expressibility score and increased pain perception compared to an untreated group of women. 相似文献

BackgroundKnowledge of the epidemiology of burn-related fatalities is limited, with most previous studies based on hospital and burn centre data only.AimsTo describe the epidemiological characteristics of all burn-related fatalities in Australia and New Zealand, and to identify any trends in burn-related fatality incidence over the study period.MethodsData from the National Coronial Information System, including data for pre-hospital and in-hospital burn-related fatality cases, was used to examine the characteristics of burn-related fatalities occurring in Australia and New Zealand from 2009 to 2015. Burn-related fatality rates per 100,000 population were estimated, and incidence trends assessed using Poisson regression analysis.ResultsOf the 310 burn-related fatalities that occurred in Australia and New Zealand, 2009–2015, 41% occurred in a pre-hospital setting. Overall, most burn-related fatality cases were fire related, occurred at home, and were of people aged 41–80 years. One quarter of all burn-related fatalities were a result of intentional self-harm. The population incidence of all burn-related fatalities combined, and for NSW, decreased over the study period.ConclusionsThis study has identified the importance of examining all burn-related fatalities. If this is not done, vulnerable population subgroups will be missed and prevention efforts poorly targeted. 相似文献
