Kirsi Hipp MNSc RN Lauri Kuosmanen PhD RN FEANS Eila Repo‐Tiihonen MD PhD Minna Leinonen MSc Olavi Louheranta PhD ThM Mari Kangasniemi PhD RN 《International journal of mental health nursing》2018,27(2):536-554
Pro re nata (PRN) medication is widely used and studied in psychiatric care, but our knowledge about patient participation in its administration is fragmented. The aim of this integrative review was to describe and synthesize previous knowledge of patient participation in PRN in psychiatric inpatient settings. We conducted both electronic and manual searches, using the CINAHL, Scopus, PsycINFO, and PubMed databases, and eight scientific journals. Searches were limited to the English language, to the years 2006–2016, and to selected papers using inclusion, exclusion, and quality criteria. We identified 16 relevant papers, and these showed that patient participation included patient‐related starting points, including the patients’ willingness to participate and their knowledge of the medication. The patients’ participation in PRN practices was demonstrated by the opportunity to request PRN and to refuse any PRN that was offered. Patient participation was shown to be linked to certain situations where PRN was recommended. The role that the professionals played in patient participation included interacting with patients, providing counselling and alternatives for PRN. Our results also revealed that coercion was used administering PRN. The existing literature exposed challenges that need to be addressed if patient participation in the use of PRN medication is to be effectively achieved in psychiatric inpatient settings. Equal partnerships between patients, nurses, and physicians are an essential part of this process, and further research into PRN medication is urgently needed, particularly studies that focus on patients’ experiences. 相似文献

Background
Preoperative anemia and allogeneic blood transfusions (ABTs) may affect outcomes in cancer surgery. The prevalence of anemia, the use of ABTs, the risks of transfusions, lengths of stay and mortality of oncological patients undergoing radical cystectomy were investigated in three University Hospitals in Germany.Patients and Methods
Hospital records of 220 consecutive patients undergoing radical cystectomy from 2010 to 2012 were retrospectively analyzed for independent risk factors of ABT and unfavorable outcomes (readmission, increased length of stay (LOS) or death) using multivariate regression analysis.Results
Preoperative anemia was present in 40%. 70% of patients received blood transfusions. Low preoperative and intraoperative nadir hemoglobin levels were associated with receipt of ABT (OR 1.33, P?=?0.04 and OR 2.94, P?<?0.001 respectively). Transfusion of ten or more red blood cell units (RBCs) during the entire hospital stay was a predictor of an increased LOS (P?<?0.001) and death (OR 52, 95%CI [5.9, 461.3], P?<?0.001), compared to non-transfused patients. Preoperative ABT and ASA scores were associated with ≥10RBCs.Conclusion
Anemic patients undergoing radical cystectomy had a high risk to receive ABTs. Preoperative transfusions and transfusion of ≥10RBCs during the entire hospital stay may increase patient`s mortality.Prospective, randomized controlled studies have to follow this study. 相似文献994.

National agencies are calling for quality improvement in primary care health care services and across the United States health care system. Changes would be directed toward improving quality of life for the chronically ill and decreasing their financial burden and that placed on society. Nurse practitioners, based on their expertise and preparation in patient education, are ideal health care providers to establish partnerships with motivated, informed, chronically ill patients and to promote change in health care policy, guidelines, and meeting patient educational needs. Within worksite primary care, nurse practitioners can, through the Chronic Care Model framework, provide chronic disease management and affordable health care access. 相似文献

Background
Diabetic patients are commonly hyperglycaemic on presentation. Admission hyperglycaemia is associated with adverse outcomes, particularly prolonged hospitalisation. Improving inpatient glycaemia may reduce length of hospital stay (LOS) in diabetic patients.Aims
To determine whether in-hospital recognition and treatment of admission hyperglycaemia in diabetic patients is associated with reduced LOS.Methods
Medical records were reviewed from 1 November 2011 to 31 May 2012 for 162 diabetic patients admitted with a blood glucose level (BGL) ≥11.1mmol/L. In-hospital outcomes were compared. Stepwise multiple regression was used to evaluate factors contributing to LOS.Results
Compared to the untreated individuals (n=67), hyperglycaemia treatment (n=95) was associated with a longer LOS (median eight vs. four days, p<0.01), higher HbA1c (9.0 vs. 7.3 per cent, p<0.01), more infections (50 vs. 25 per cent, p<0.01), and more patients with follow-up plans (35 vs. 10 per cent, p<0.01). Higher HbA1c was significantly related to more follow-up (ρs=0.30, n=110, p<0.01) with a trend to lower re-admission in those with follow-up plans (ρs=-1.41, n=162, p=0.07).Conclusion
Recognition and treatment of admission hyperglycaemia in diabetic patients was associated with longer LOS than if untreated. Contributory factors to LOS include: illness severity, infections, and higher HbA1c. Although follow-up plans were few (27 per cent) for diabetic patients with hyperglycaemia, it was significantly more likely in those with higher HbA1c. Diabetic patients’ complexities require timely multidisciplinary team involvement. Improved follow-up care, particularly for hospitalised diabetic patients identified to have chronically poor glycaemic control, may help prevent future diabetic patient re-admissions. 相似文献996.

Intravenous (IV) fluid administration is one of the most common interventions in the hospital setting. The associated complication rate is higher than previously believed, with adverse effects impacting recovery, length of stay, cost, patient safety, and survival. Several patient populations are at increased risk, and there are substantial data implicating inappropriate fluid administration as a contributing factor to increased morbidity and mortality. Related complications are largely preventable, and unmet educational needs are well-documented. An increase in evidence-based management has the potential to improve outcomes related to a number of quality indicators. 相似文献

ObjectiveTo evaluate outcomes of a registered nurse–led care management intervention for disabled Medicaid beneficiaries with high health care costs.ConclusionsWe found no health care cost savings for disabled Medicaid beneficiaries randomized to intensive care management. Among participants, care management may have the potential to increase access to needed care, slow growth in the number and therefore cost of unplanned hospitalizations, and prevent homelessness. These findings apply to start-up care management programs targeted at high-cost, high-risk Medicaid populations. 相似文献

With the explosive economic growth and social development, China’s regulatory system of
occupational health and safety now faces more and more challenges. This article reviews
the history of regulatory system of occupational health and safety in China, as well as
the current reform of this regulatory system in the country. Comprehensive, a range of
laws, regulations and standards that promulgated by Chinese government, duties and
responsibilities of the regulatory departments are described. Problems of current
regulatory system, the ongoing adjustments and changes for modifying and improving
regulatory system are discussed. The aim of reform and the incentives to drive forward
more health and safety conditions in workplaces are also outlined. 相似文献

ObjectivesTo evaluate the utilization of a policy for strengthening general practitioner's case management and quality of care of diabetes patients in Denmark incentivized by a novel payment mode. We also want to elucidate any geographical variation or variation on the basis of practice features such as solo- or group practice, size of practice and age of the GP.MethodsOn the basis registers encompassing reimbursement data from GPs and practice specific information about geographical location (region), type of practice (solo- or group-practice), size of practice (number of patients listed) and age of the GP were are able to determine differences in use of the policy in relation to the practice-specific information.ResultsAt the end of the study period (2007–2012) approximately 30% of practices have enrolled extending services to approximately 10% of the diabetes population. There is regional – as well as organizational differences between GPs who have enrolled and the national averages with enrolees being younger, from larger practices and with more patients listed.ConclusionsOur study documents an organizationally and regionally varied and limited utilization with the overall incentive structure defined in the policy not strong enough to move the majority of GPs to change their way of delivering and financing care for patients with diabetes within a period of more than 5 years. 相似文献
