Adherence to Hepatitis B Antiviral Therapy: A Qualitative Study.

Hepatitis B virus (HBV) antiviral therapies potentially suppress HBV viral load to an undetectable level reducing the risk of progressive liver disease and the development of HBV-related hepatocellular carcinoma. Adherence to antiviral therapies is imperative to achieve and maintain viral suppression. To date, there has been limited research on adherence to HBV therapies. Our study aimed to explore factors influencing adherence to antiviral therapy. A total of 29 participants consented to in-depth qualitative interviews at three outpatient clinics in Sydney, New South Wales, Australia. Interviews were digitally recorded and transcribed. Transcripts were initially classified as adherent or nonadherent and thematic analysis was used to identify dominant themes. Adherent behavior was reported by 59% (n = 17) of participants. Several themes influenced adherence including routine, fear of HBV-related disease progression, clinician-patient communication, treatment knowledge, and forgetfulness. To our knowledge, this is the first qualitative study to explore adherence to HBV antiviral therapy. An interplay of several dominant themes emerged from our data including fear of chronic HBV disease progression, clinician-patient communication, treatment knowledge, routine, and forgetfulness. Study findings have the potential to change nursing clinical practice, especially the way nurses and other clinicians target key HBV treatment messages and education, while monitoring adherence.

Factors contributing to nursing team work in an acute care tertiary hospital.

Background: Effective nursing teamwork is an essential component of quality health care and patient safety. Understanding which factors foster team work ensures teamwork qualities are cultivated and sustained. Objective: This study aims to investigate which factors are associated with team work in an Australian acute care tertiary hospital across all inpatient and outpatient settings. Methods: All nurses and midwives rostered to inpatient and outpatient wards in an acute care 600 bed hospital in Sydney Australia were invited to participate in a cross sectional survey between September to October 2013. Data were collected, collated, checked and analysed using Statistical Package for the Social Sciences (SPSS) Version 21. Factors reporting a significant correlation with where p < 0.05 were analysed in a multiple regression model. Results: A total of 501 surveys were returned. Nursing teamwork scores ranged between 3.32 and 4.08. Teamwork subscale Shared Mental Model consistently rated the highest. Mean scores for overall communication between nurses and team leadership were 3.6 (S.D. 0.57) and 3.8 (SD 0.6) respectively. Leadership and communication between nurses were significant predictors of team work p < 0.001. Conclusion: Our findings describe factors predictive of teamwork in an acute care tertiary based hospital setting across inpatient and outpatient specialty units. Our findings are of particular relevance in identifying areas of nurse education and workforce planning to improve nursing team work.

Factors associated with medication adherence in patients living with cirrhosis.

AIMS AND OBJECTIVES: Medication adherence in people with cirrhosis is largely unknown. This study aims to determine adherence patterns and factors associated with adherence in patients with cirrhosis. BACKGROUND: Prescribed medications are a pivotal component in the clinical management of cirrhosis with potential to retard disease progression and reduce complication risks. Medication adherence is necessary to optimise health outcomes. Understanding why medications are missed may help to develop strategies and inform nursing practice. DESIGN: Prospective cohort study. METHODS: Participants (n = 29) diagnosed with cirrhosis attending a tertiary hospital consented to complete a self-reported survey. Demographic information, adherence to medications, patient knowledge and quality of life data were collected, collated, checked and analysed using SPSS version 21. RESULTS: Less than half of the 28 patients who completed the adherence questionnaire (n = 13, 46%) reported that they had never missed medication. Being forgetful, being away from home and falling asleep contributed to nonadherence. Having less abdominal symptoms, less fatigue and increased emotional well-being were significantly associated with patients never missing medications. CONCLUSIONS: To our knowledge this is the first published study to describe adherent behaviour and the reasons medications are missed in this population. The percentage of nonadherent participants is of concern considering the potential morbidity risk that is associated with missed medications and rebound symptoms of cirrhosis. Strategies to improve and sustain adherence levels are required including enhanced adherence counselling offered to patients who are deteriorating or experience periodic exacerbation of symptoms. RELEVANCE TO CLINICAL PRACTICE: Study findings have the potential to change clinical practice especially the way nurses target motivational adherence counselling, key treatment messages, education and adherence monitoring. The results presented here provide a basis for developing adherence strategies and nursing management plans to improve adherence and health outcomes in people with cirrhosis.

Childhood hepatitis C virus infection: An Australian national surveillance study of incident cases over five years.

AIM: An estimated 1.1% of Australian adults are infected with hepatitis C virus (HCV). Many develop chronic liver disease, and some develop liver failure or hepatocellular carcinoma. HCV infection in Australian children is poorly defined. We aimed to determine the reported incidence, clinical and epidemiological features of newly diagnosed HCV infection in Australian children presenting to paediatricians. METHODS: We undertook prospective active national surveillance, using the Australian Paediatric Surveillance Unit, of incident HCV cases in children aged <15 years between 1(st) January 2003, and 31(st) December 2007. RESULTS: There were 45 confirmed cases of newly diagnosed HCV infection over five years (<1 per 100,000 children aged <15 years per year). Median age at diagnosis was 2.9 years. Positive maternal HCV serostatus was the most frequent reported risk factor for HCV infection in children (40/45). Three children (all aged > 14), were exposed through their own IV drug use. No children were co-infected with HIV and only one child was co-infected with HBV. All children were asymptomatic at diagnosis, although many had minor elevations in liver transaminases. Many clinicians reported difficulties with follow-up. CONCLUSIONS: Childhood HCV infection is uncommon in Australia, although our data likely underestimate the incidence. Only a small number of children aged <18 months was identified, despite known perinatal exposure. Opportunistic investigation of children at risk for HCV, improved education regarding vertical transmission for health care providers, and increased coordination of childhood HCV services are required to improve recognition and management of children with HCV.

Similarities and Differences in Nurse-Reported Care Rationing Between Critical Care, Surgical, and Medical Specialties.

OBJECTIVE: The aim of this study was to determine the similarities and differences in elements of nursing care that are commonly rationed in the critical care, medical, and surgical specialties within an acute hospital environment. METHODS: Registered nurses who provide bedside nursing care within the medical, surgical, and critical specialties at a single center were invited to anonymously complete the self-administered MISSCARE questionnaire. The frequency of rationing for each individual care element within the 4 broader care groups (assessment, intervention-individual needs, intervention-basic care, and planning) of the MISSCARE questionnaire was determined. A mean score for each care group was also determined, and multiple regression analysis was undertaken to determine the demographic predictors of care rationing. RESULTS: Interventions related to basic care was the most frequently rationed care group in the critical care/emergency specialty (missed care mean of 50.1%), whereas planning was the most frequently rationed care group among both the medical (missed care mean of 43.6%) and surgical (missed care mean of 44.8%) specialties. Assessment was the least frequently rationed care group among all 3 specialties (missed care mean of 19.7%-26.7%). Length of time practicing as a registered nurse was an independent predictor of care rationing in the critical care/emergency specialty, and age older than 50 was an independent predictor in the medical specialty. CONCLUSIONS: There are numerous similarities and differences in care rationing between critical care, surgical, and medical nurses. The development and implementation of specialty-based strategies should be undertaken to reduce the incidence of nursing care rationing.

Risk factors and seroprevalence of markers for hepatitis A, B and C in persons subject to homelessness in inner Sydney.

OBJECTIVE: To determine the seroprevalence of hepatitis A, B and C and the prevalence of risk factors for blood-borne infections in persons subject to homelessness attending a medical clinic in inner Sydney. METHOD: During 2003-05, 201 clients were enrolled in a prospective study to determine the acceptance, completion rates and immunogenicity of the standard vaccination schedule for hepatitis A and B. On enrolment, clients completed a risk factor assessment questionnaire and undertook pre-vaccination serological screening for hepatitis A, B and C. RESULTS: Forty-five per cent (85/188) of clients were positive for anti-HCV antibodies; 32% (60/189) showed evidence of past infection with HBV (anti-HBc); and 48% (89/189) were positive for anti-HAV antibodies. It was not uncommon for clients to have multiple markers of hepatitis. A past history of injecting drug use was significantly associated with markers for hepatitis B and C; age predicted presence of anti-HAV. A verbal history of infection appeared more reliable for hepatitis C, but considerably less so for hepatitis A and B. CONCLUSION: Persons subject to homelessness are at risk of blood-borne infection. The seroprevalence of markers for hepatitis B and C are higher than in the general population. IMPLICATIONS: Despite the high proportion of clients with serological markers for hepatitis A and B, at least 69% of clients could potentially benefit from hepatitis A and/or B vaccination.

Impact of physical and psychological factors on health-related quality of life in adult patients with liver cirrhosis: a systematic review protocol.

REVIEW QUESTION/OBJECTIVE: What is the impact of physical and psychological factors on health-related quality of life in adult patients diagnosed with liver cirrhosis? BACKGROUND: All chronic liver diseases stimulate a degree of repetitive hepatocyte injury that alters the normal liver architecture and ends in cirrhosis.Liver cirrhosis and hepatocellular carcinoma secondary to livercirrhosis are a major public health burden, reporting increasing mortality and morbidity both in Australia and globally.The four leading causes of cirrhosis include harmful alcohol consumption, viral hepatitis B and C and metabolic syndromes related to non-alcoholic fatty liver disease and obesity.A cirrhotic liver is characterized by the presence of regenerative nodules surrounded by fibrous bands that inhibit the passing of molecules between blood and functional units of liver hepatocytes, leading to liver dysfunction.Additionally, the presence of fibrous bands disrupts the normal vascular architecture, increasing resistance within the liver sinusoids and contributing to increased portal vein pressure.The early stages of cirrhosis are referred to as compensated liver disease with no reported symptoms or evidence of impaired liver function.However, the signs and symptoms of liver failure, as well as the mortality rate, increase as the severity of cirrhosis increases.Transition from compensated to decompensated cirrhosis is marked by one or more physiological changes. The physiological changes include increased portal vein pressure, impaired synthetic function, electrolyte imbalance and malnourishment.These physiological changes trigger the development of physical signs and symptoms and impact on the psychological wellbeing of the individual living with cirrhosis. The physical signs and symptoms include esophageal varices, ascites, hepatic encephalopathy, jaundice, irregular sleep patterns, muscle cramps, pruritus, fatigue, impaired mobility, breathlessness, abdominal discomfort, gastrointestinal symptoms, change of body image and pitting edema.Psychological symptoms include stress, depression and anxiety.Living with liver cirrhosis has a marked impact on the quality of life of the individual. Health-related quality of life (HRQOL) is the individual's perception of their physical, cognitive, emotional and social functioning.Studies report that physical and psychological factors affect the quality of life of patients with cirrhosis which can be problematic and debilitating.There is strong evidence which indicates that disease severity is associated with an impairment of the patient's HRQOL.For example, gross ascites causes abdominal discomfort, breathlessness, increased stress and anxiety related to body image, immobility and an increased likelihood of falls. In addition, the management of ascites involves frequent invasive procedures, an increase in pill burden and implementation of dietary restrictions, all of which impact on HRQOL.Despite the clear relationship between HRQOL and severity of disease, there has been no systematic review undertaken to determine the physical, psychological and physiological factors that affect the HRQOL of patients with liver cirrhosis. This systematic review will therefore identify the best available evidence related to the impact of physical, psychological and physiological factors on the health-related quality of life of adult patients with liver cirrhosis. The results of the review will increase clinicians' knowledge and highlight areas of clinical management that may require additional strategies and treatment plans to improve symptom relief and HRQOL.

Spontaneous Clearance of Hepatitis C Virus during Pregnancy.

Spontaneous clearance of hepatitis C virus (HCV) is expected to be unlikely in pregnancy due to the relative immunosuppression and increase in viraemia that occurs. We report the first case of spontaneous clearance of hepatitis C virus (HCV) occurring in pregnancy.
