Understanding clinical risk decision making regarding development of depression during interferon-alpha treatment for hepatitis-C: a qualitative interview study

Nurse Decision Making in Acute Care

Effective nurse decision making is essential for best patient outcomes in the acute care nurse practice environment. The purpose of this study was to explore acute care RNs' perceptions of clinical decision making for a patient who experienced a clinical event. Clinical events include changes in patient condition and are manifested by fever, pain, bleeding, changes in output, changes in respiratory status, and changes in level of consciousness. Naturalistic decision making framework supported the exploration of important contextual factors associated with decision making, provided new information for nursing science, and served as the conceptual framework for this research. Data collected from interviews of 20 acute care nurses were analyzed using qualitative content analysis. The emergent categories included Awareness of Patient Status, Experience and Decision Making, Following Established Routine, Time Pressure, Teamwork/Support From Staff, Goals, Education, Resources, Patient Education, Consideration of Options to Meet Goals, and Nursing Roles. Acute care nurses incorporated a wide variety of complex factors when decision making. This study sought to improve understanding of the factors nurses found important to their decision making for the potential development of improved decision support in the electronic health record.

Deriving the Practice-Primed Decision Model from a naturalistic decision-making perspective for acute care nursing research

AIM

The purpose of this article is to present the derivation of the Practice Primed Decision Model from a naturalistic decision-making framework for use in guiding future nursing decision-making research.

BACKGROUND

Acute care nurses make decisions in demanding environments under the influence of many factors. The influence of these factors on nurse decision-making is not well understood leading to gaps in understanding how to best support acute care nurse decision-making.

METHODS

The strategy of theory derivation was used in the development of a new model for use in nursing research. This model incorporates important elements identified in naturalistic decision making, a Recognition Primed Decision Model and an integrative review of nurse decision-making literature.

CONCLUSION

The new model, Practice Primed Decision Model, provides a new perspective to guide nurse decision-making research. This model includes factors influential to the nurse decision-making process that is more realistic in time limited, high stakes decision-making situations.

Effects of oral hygiene programme and home phone counselling for hepatitis C patients receiving antiviral treatment

AIMS

To explore the effectiveness of an oral hygiene programme combined with home phone counselling on hepatitis C patients during antiviral treatment.

BACKGROUND

Hepatitis C virus infection is the leading cause of liver diseases. Evidence indicates that the antiviral treatment for hepatitis C virus infection has been successful, albeit its many side effects, such as discomfort symptoms of oral ulcers, which, in turn, leads to discontinued treatment. Inappropriate oral hygiene may worsen the side effects and increase the risk of dropping out of the treatment.

DESIGN

A quasi-experimental pre-post-test design was used.

METHODS

The oral hygiene programme was based on a standardized protocol of oral health care combined with home phone counselling. The participants were recruited from an outpatient clinic between August 2016 and July 2017. The generalized estimating equation was used for repeated measures of oral health behaviour, oral health status and discomfort symptoms.

FINDINGS

Thirty-four participants completed this study. The findings indicated that the oral hygiene programme significantly improved tooth brushing, use of dental floss and oral comfort. The result showed that the participants' oral health status significantly improved in 3 months.

CONCLUSIONS

This pilot study supports the finding that an oral hygiene programme can reduce oral discomfort, improve oral hygiene behaviour, and enhance the oral health status of hepatitis C patients receiving treatment. This is a simple and low-cost programme, which can be performed at home easily and boosts the completion of antiviral treatment.

Illness Experience of Patients with Chronic Hepatitis C Participating in Clinical Trials

Objectives

To understand the illness experience of patients with chronic hepatitis C participating in clinical trials in the sociocultural context of Korea in an in-depth and comprehensive manner.

Methods

A focused ethnography approach was used to discover the pattern of illness experience of patients with chronic hepatitis C in the cultural background of Korea. Interviews were conducted with 11 patients with chronic hepatitis C participating in clinical trials and the collected data were analyzed with the domain analysis, taxonomical analysis, componential analysis, and theme analysis proposed by Spradley.

Results

With the cultural theme of “less-known illness, less-familiar illness,” four categories were derived: “my illness discovered by accident,” “shaken life,” “scary but inevitable treatment method,” and “precious life that can't be wasted,” along with 12 properties.

Conclusion

Public campaigns or education programs are needed to meet the needs for information on the disease for patients with chronic hepatitis C participating in clinical trials and help the general public acquire knowledge or change view on this disease.

Designing for Risk Assessment Systems for Patient Triage in Primary Health Care: A Literature Review

Background

This literature review covers original journal papers published between 2011 and 2015. These papers review the current status of research on the application of human factors and ergonomics in risk assessment systems’ design to cope with the complexity, singularity, and danger in patient triage in primary health care.

Objective

This paper presents a systematic literature review that aims to identify, analyze, and interpret the application of available evidence from human factors and ergonomics to the design of tools, devices, and work processes to support risk assessment in the context of health care.

Methods

Electronic search was performed on 7 bibliographic databases of health sciences, engineering, and computer sciences disciplines. The quality and suitability of primary studies were evaluated, and selected papers were classified according to 4 classes of outcomes.

Results

A total of 1845 papers were retrieved by the initial search, culminating in 16 selected for data extraction after the application of inclusion and exclusion criteria and quality and suitability evaluation.

Conclusions

Results point out that the study of the implications of the lack of understanding about real work performance in designing for risk assessment in health care is very specific, little explored, and mostly focused on the development of tools.

Management of viral hepatitis in liver transplant recipients

Recurrence of viral hepatitis after liver transplantation (LT) can progress to graft failure and lead to a decrease in long-term survival. Recently, there have been remarkable improvement in the treatment of chronic hepatitis B (CHB) using potent antiviral agents. Combination of hepatitis B immunoglobulin and potent antiviral therapy has brought marked advances in the management of CHB for liver transplant recipients. Post-transplant antiviral therapy for hepatitis C virus infection is generally reserved for patients showing progressive disease. Acheiving a sustained virological response in patients with LT greatly ameliorates graft and overall survival, however this only occurs in 30% of transplant recipient using pegylated interferon and ribavirin (RBV). Direct acting antivirals such as protease inhibitors, polymerase or other non-structural proteins inhibitors are anticipated to establish the new standard of care for transplant recipients. In liver transplant recipients, hepatitis E virus infection is an uncommon disease. However, it can lead to chronic hepatitis and cirrhosis and may require retransplantation. Recently, 3-month course of RBV monotherapy has been reported as an effective treatment. This review focuses on the recent management and therapeutic approaches of viral hepatitis in liver transplant recipient.

N-acetyl-cysteine prevents toxic oxidative effects induced by IFN-α in human neurons

Currently IFN-α is widely used for effective treatment of viral infections and several malignancies. However, IFN-α can cause neuropsychiatric disturbances and mental impairments, including fatigue, insomnia, depression, irritability and cognitive deficits. Molecular and cellular mechanisms leading to such side-effects are still poorly understood. Neurons seem to be an important target in mediating cellular effects induced by exposure to this cytokine, but so far little is known about IFN-α-induced effects on these cells. We have investigated the ability of IFN-α (2-100 ng/ml) to induce damage and toxicity to the human neuroblastoma SH-SY5Y cell line, commonly used for studying such phenomena, and the mechanisms underlying these effects. After 24 h treatment, IFN-α increased mitochondrial activity, whereas cell density was reduced in a dose- and time-dependent manner. This effect did not depend on reduced cell proliferation, but rather the activation of apoptosis, as revealed by an increased Bax:Bcl-2 mRNA ratio after 72-h IFN-α exposure. At this time-point, IFN-α also reduced the expression of the brain-derived neurotrophic factor gene, and induced an increase in reactive oxygen species (ROS). A co-treatment with N-acetyl-cysteine (NAC; 5 mm), a potent antioxidant and mitochondrial modulator, was able to counteract all of these IFN-α-induced effects. These findings demonstrated that IFN-α induces neurotoxicity and apoptosis that is, in part, very likely due to mitochondrial damages and production of ROS. We suggest that NAC, already tested for the treatment of psychiatric disorders, may be useful to prevent IFN-α-induced central side-effects in a safe and effective way.
