Development of an evidence-based hepatitis C education program to enhance public health literacy in the Australian prison sector: The Hepatitis in Prisons Education program (HepPEd)

BACKGROUND

Australia's prisons have a high chronic hepatitis C (HCV) prevalence (8 %). Antiviral therapies and prison-based hepatitis services are available, but only a minority of those eligible are being treated. Improving the HCV public health literacy of the prison sector via targeted education may overcome key barriers to scale-up treatment. This paper describes the: i) HCV public health literacy of the prison setting; ii) barriers and solutions for HCV education and service engagement; iii) HCV education program co-design and development processes; and iv) HepPEd resources.

METHODS

A national needs assessment was conducted to analyse the HCV public health literacy of the target audience groups in the prisons (healthcare providers; custodial officers; people in prison) to inform development of a prison-specific HCV education program (HepPEd). Structured interviews were conducted with key informants (n = 40). Three National Steering Committees, one for each target group, were convened to co-design and develop HepPEd.

RESULTS

Only healthcare providers involved with hepatitis care were considered to have 'good' to 'very good' HCV health literacy (including knowledge, attitudes, and capabilities), with all other groups considered less favourably. Key barriers identified included being time poor (healthcare providers), poor motivation (custodial officers) and stigma (people in prison). Peer education delivery was considered a key facilitator for custodial officers and people in prison. A suite of multi-modal resources addressing the perceived gaps in HCV health literacy was developed, with a broad theme of 'Let's talk about hep C'. Delivery of HepPEd was designed to overcome key barriers and utilise facilitators for each group.

CONCLUSIONS

Significant gaps in HCV health literacy were perceived amongst the target audience groups. The comprehensive co-design and development processes utilised in HepPEd suggest the program will be well-placed to improve the HCV public health literacy of the prison sector and thereby enhance HCV testing and treatment rates amongst people in prison.

Knowledge, attitude and practice towards hepatitis B infection among high school students in Asante Mampong, Ghana

BACKGROUND

Hepatitis B virus (HBV) infection is a serious global public health problem, with significant morbidity and mortality from acute and chronic complications. Increasing awareness and improving knowledge of HBV helps reduce the risk of the disease. Although many studies have been conducted on HBV in Ghana, few have focused on examining knowledge, attitude and preventive practices among adolescents towards the disease.

OBJECTIVE

The objective of this study was to assess HBV knowledge, attitude and practice (KAP) among adolescents in high schools in the Asante Mampong Municipality in the Ashanti Region of Ghana.

METHODS

A descriptive cross-sectional study was conducted among 398 adolescents from six senior high schools within the Asante Mampong Municipality. Data was collected using a 30-item structured questionnaire. Each item had two response options: "Yes" and "No". A scoring system was generated and respondents were given a score on each item answered. A positive response to an item was scored 1 point and a negative response was scored 0. Scores were then summed up and averaged to give the mean knowledge, attitude and practice scores.

RESULTS

The majority of the respondents were male (60%), between 15 and 17 years (45%), Christian (93%) and in their first year of study. The adolescents had basic knowledge, positive attitude, and poor practices towards HBV. There was no significant relationship between the demographic variables of the respondents and KAP mean scores.

CONCLUSION

There is the need to introduce health education and awareness programs in schools within the Asante Mampong Municipality to improve students' level of knowledge of HBV. Countrywide studies examining KAP towards HBV infection among adolescents are also warranted.

A Patient-Centered Hepatitis B Virus (HBV) Educational Intervention Improves HBV Care Among Underserved Safety-Net Populations

GOALS

To evaluate the impact of a prospective patient-centered hepatitis B virus (HBV) educational intervention on improving HBV care.

BACKGROUND

Improving patients' HBV knowledge has the potential to improve adherence to HBV monitoring and management, particularly among underserved safety-net populations.

METHODS

Consecutive chronic HBV adults at a single-center safety-net liver clinic were recruited from July 2017 to July 2018 to evaluate the impact of an in-person, language concordant formal HBV educational intervention on improvements in HBV knowledge and HBV management: appropriate HBV clinic follow-up (≥1 visit/year), HBV laboratory monitoring (≥1 HBV viral load and alanine aminotransferase test/year), hepatocellular carcinoma surveillance (≥1 liver imaging test/year among eligible patients), and HBV treatment among treatment eligible patients. HBV knowledge and management were assessed before and after the intervention and compared with age-matched and sex-matched HBV controls who did not receive an education.

RESULTS

Among 102 patients with chronic HBV (54.9% men; mean age, 52.0±13.8), HBV education improved HBV knowledge scores by 25% (P<0.001), HBV clinic follow-up from 25.5% to 81.4% (P<0.001), HBV laboratory monitoring from 62.8% to 77.5% (P=0.02), and appropriate HBV treatment from 71.5% to 98.5% (P<0.001). Compared with 102 HBV controls, receiving HBV education was associated with higher rates of HBV clinic follow-up (81.4% vs. 39.2%; odds ratio, 7.02; 95% confidence interval, 3.64-13.56; P<0.001) and appropriate HBV laboratory monitoring (77.5% vs. 42.2%; odds ratio, 4.94, 95% confidence interval, 2.64-9.24; P<0.001).

CONCLUSION

A formal, in-person, language concordant educational intervention leads to significant improvements in HBV knowledge, resulting in improved HBV monitoring and appropriate HBV treatment.

Education provides significant benefits to patients with hepatitis B virus or hepatitis C virus infection: a systematic review

BACKGROUND & AIMS

Education of individuals who are at risk for, or have been diagnosed with, chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infections can improve their participation in disease management. We performed a systematic review to evaluate the effects of educational interventions for patients with HBV or HCV infections.

METHODS

We searched multiple databases for peer-reviewed studies of individuals with HBV or HCV infection, or those at risk for infection. Our final analysis included 14 studies that evaluated any educational intervention and reported the effectiveness or patient outcomes relevant to the intervention (7 patients with HCV infection, 4 patients with HBV infection, and 3 patients with either). Data extracted from studies included details on educational interventions, patient populations, comparison groups, and outcome measures. The quality of each study was appraised.

RESULTS

Types of educational interventions assessed ranged from information websites and nurse-led sessions to community-wide and institutional programs. The educational interventions showed significant (P < .05) improvements to patients' knowledge about their disease, behaviors (including testing and uptake of vaccination), willingness to commence and adhere to treatment, and other outcomes such as self-efficacy and vitality or energy scores. These significant benefits were shown in 5 of 7 studies of HBV infection and 8 of 10 studies of HCV infection. On a 20-point quality scale, study scores ranged from 6 to 19.

CONCLUSIONS

Simple educational interventions for patients with HBV or HCV infection significantly increase patients' knowledge about their disease. More complex, multimodal educational interventions seem to cause behavioral changes that increase rates of testing, vaccination (for HBV), and treatment.

Screening high risk individuals for hepatitis B: physician knowledge, attitudes, and beliefs

BACKGROUND

Although the overall incidence of hepatitis B virus (HBV) has declined since the introduction of universal vaccine guidelines, the incidence remains elevated in high risk groups. Recent guidelines from the Centers for Disease Control (CDC) have underscored the importance of vaccination against HBV in high risk individuals. However, the incidence of HBV in this group remains elevated, suggesting underuse of vaccinations by healthcare providers.

AIM

The purpose of this study was to measure practice patterns of HBV vaccination, and identify predictors of vaccination underuse.

METHODS

We created a survey with four vignettes describing patients at high risk for contracting HBV, followed by questions regarding knowledge, attitudes, and beliefs (KAB) of HBV screening and vaccination. A random sample of 1,000 physicians, including internists, family medicine, OB/GYN, gastroenterologists, and experts in HBV epidemiology were surveyed. Regression analysis on composite guideline adherence scores identified KAB profiles that predict scores.

RESULTS

On average, responders endorsed 71% of the CDC HBV vaccination guidelines. There were three predictors of diminished screening proclivity: (1) younger provider age (P = 0.028), (2) lower awareness that adult HBV is contracted primarily through heterosexual sex (P = 0.023), and (3) being a provider other than a gastroenterologist (P = 0.009).

CONCLUSIONS

Respondents endorsed most-but not all-CDC supported HBV screening practices. Lower adherence was predicted by specific and modifiable KAB profiles, and by younger age. Future efforts to improve adherence should target trainees, emphasize the importance of obtaining sexual histories in high risk patients, and inform that HBV is predominantly a heterosexually transmitted infection.

Hepatitis B risks and immunization coverage among American travelers

BACKGROUND

Hepatitis B is endemic in much of Asia, Africa, and parts of South America, regions that are increasingly popular destinations for American travelers. The frequency of hepatitis B risks during travel has been examined for Europeans but not Americans. Further, limited data are available to describe the domestic hepatitis B risk factors of American travelers, the proportion vaccinated, and whether immunization activities target travelers at highest risk. We conducted a survey of international travelers to address these issues.

METHODS

A survey was mailed to 884 American international travelers, of whom 618 (70%) responded. The survey covered demographic and travel characteristics, sources of pre-travel health advice, immunization status, and items needed to assess hepatitis B vaccination candidacy. Travel-specific items concerned the most recent trip to a hepatitis B endemic region. Hepatitis B risk during the most recent trip was classified as high, potential, or none based on potential exposure to blood or bodily fluids.

RESULTS

Only 31% of respondents visited any health practitioner to obtain pre-travel health advice; 13% visited a travel medicine specialist. Totally 45% of respondents reported (3)1 domestic or travel-related hepatitis B risk, and 8% were at high risk during travel. Risk factors were more common among younger travelers and those with longer travel durations. Travel medicine specialists were more likely than nonspecialists to provide hepatitis B vaccine (40% vs 21%, p= 0.01). Travelers with risk factors were no more likely to be vaccinated in specialist or nonspecialist settings. Upon departure, only 19% of all travelers and 30% of travelers with risk factors had received three or more hepatitis B vaccine doses.

CONCLUSIONS

Most US travelers to hepatitis B endemic regions do not secure pre-travel health advice, and most have not received three doses of hepatitis B vaccine. A substantial share are candidates for hepatitis B vaccination based on their domestic activities, and/or face hepatitis B risks during travel.

Review of Clinical Trials Testing the Effectiveness of Clinician Intervention Approaches to Prevent Sexually Transmitted Diseases in Adolescent Outpatients

OBJECTIVE

Identify approaches for improving clinician provision of sexually transmitted diseases (STDs) prevention services among outpatient adolescents.

METHODS

Reviewed all peer-reviewed, published clinical trials identified through computerized searches (MEDLINE, PsychINFO) evaluating STD prevention services to outpatient adolescents by clinicians.

RESULTS

Five trials were identified examining changes in clinician provision of STD prevention services. Two of these trials resulted in adolescent self-reported risk reduction but neither of these trials effectively demonstrated reductions in objectively measured STD incidence. Nine clinical trials were identified that compared clinician with non-clinician provision of STD prevention services. Four of these trials resulted in adolescent self-reported risk reduction, and one of these trials demonstrated a reduction in objectively measured STD incidence.

CONCLUSIONS

Trials indicate that improvement in outpatient adolescent STD incidence is possible with non-clinicians as interventionists, and perhaps clinicians as interventionists if clinicians are supported by other educational resources. Opportunities for personalized, interactive adolescent education appears key to intervention success. The clinician role that is tested in most trials is confined to a single brief encounter with little attention to: development of clinician skills, quality of psychosexual risk assessment and tailoring to meet individual adolescent need, systems-level resources and supports, the parental role, or the impact of incorporating prevention into an ongoing adolescent-clinician relationship.

Hepatitis C prevention with nurses

A state campaign to educate nurses about hepatitis C and encourage nurses to fight the epidemic provided an opportunity to assess the relationship between information and safety practices. Baseline and follow-up surveys were sent to random, representative samples (n = 6000) of licensed nurses in Massachusetts, USA. Responses received by 42% (n = 2443) at baseline and 37% (n = 2167) at follow-up were compared to explore the relationship between receiving information and propensity to counsel patients or use safety equipment. Only data from nurses in direct patient care were analyzed. Although few changes were observed, the assessment provided further evidence that more than a single intervention is needed to achieve health behavior change. The number of nurses who never used safety equipment did decrease slightly, from 13.3% (191) to 8.2% (132), and nurses who received information were more likely to talk to patients about the virus: 49% (414) compared to 21% (120). Hepatitis information aimed at nurses may help control this emerging epidemic.

Adolescents' knowledge, beliefs, and behaviors regarding hepatitis B: Insights and implications for programs targeting vaccine-preventable diseases

PURPOSE

To gain a better understanding of adolescents' knowledge, beliefs, and behaviors regarding hepatitis B.

METHOD

Three types of data were collected as part of this investigation: (a) 45 in-depth individual interviews with staff from 20 adolescent health, sexually transmitted disease (STD), and family planning clinics; (b) 96 individual interviews with adolescents and young adults; and (c) questionnaires completed by 17,063 adolescents and young adults. All instruments focused on one or more of the following five topics: (a) knowledge about vaccines; (b) knowledge about hepatitis B; (c) barriers to vaccine acceptance, and ways to overcome these barriers; (d) benefits of the vaccine acceptance, and ways to enhance these benefits; and (e) eight hepatitis B risk factors. Interview data was analyzed using qualitative thematic note-based analyses. Survey data was analyzed using descriptive statistics and Chi-square tests.

RESULTS

Adolescents and young adults seen in these clinics know very little about vaccinations in general, or hepatitis B, in particular. Adolescents exhibit low levels of perceived susceptibility, severity, response efficacy, and self-efficacy toward hepatitis B and the hepatitis B vaccine. On average, these adolescents engage in 2.36 high-risk behaviors (the most frequent of which include sexual activity, body piercing, and tattooing). Those who were sexually active, had a tattoo, had a STD, or worked with blood were significantly more likely to begin the vaccination series.

CONCLUSIONS

There is a clear need for additional educational efforts regarding both vaccinations in general, and hepatitis B in particular. Though adolescents are engaging in a variety of high-risk behaviors, most perceive their risk to be low, and therefore many are not taking the necessary precautions to protect themselves.

The cost effectiveness of hepatitis immunization for US college students

Hepatitis B immunization is recommended for all American children, and hepatitis A immunization is recommended for children who live in areas with elevated disease rates. Because hepatitis A and B occur most commonly in young adults, the authors examined the cost effectiveness of college-based vaccination. They developed epidemiologic models to consider infection risks and disease progression and then compared the cost of vaccination with economic, longevity, and quality of life benefits. Immunization of 100,000 students would prevent 1,403 acute cases of hepatitis A, 929 cases of hepatitis B, and 144 cases of chronic hepatitis B. Hepatitis B vaccination would cost the health system $7,600 per quality-adjusted life year (QALY) gained but would reduce societal costs by 6%. Hepatitis A/B vaccination would cost the health system dollar 8,500 per QALY but would reduce societal costs by 12%. Until childhood and adolescent vaccination can produce immune cohorts of young adults, college-based hepatitis immunization can reduce disease transmission in a cost-effective manner.

The cutaneous manifestations of viral hepatitis

Viral hepatitis is a common disease with significant morbidity and mortality that is found throughout the world. It is a known cause of acute and chronic liver disease. Because the disease can be asymptomatic in its acute stages, the diagnosis is often missed. This article reviews the extrahepatic manifestations of the disease, in particular the visible cutaneous lesions, which offer clues to the diagnosis of viral hepatitis. Familiarity with the most common skin lesions associated with each type of hepatitis virus will be useful in identifying previously undiagnosed individuals. This article serves as a review of the most widely published associations between skin diseases and specific subtypes of viral hepatitis.

Hepatitis B immunization in postpartum women

OBJECTIVE

To investigate the acceptance and efficacy of hepatitis B immunization in women during the postpartum period.

STUDY DESIGN

A group of 157 consecutive women who were delivered of neonates between 1994 and 1999 under the care of a private, full-time faculty-based practice of obstetrics and gynecology participated in the study. All patients were screened for hepatitis B surface antigen and antibody during their pregnancy. Susceptible patients eligible for hepatitis B immunization were offered the vaccine in the immediate postpartum period. The planned vaccine administration was a series of 3 intramuscular injections, with the second injection given 4 weeks later and the third given 6 months after the initial injection. Rescreening for hepatitis B surface antibody titers was performed at a visit after the last injection. Response to the immunization series was evaluated according to rate of acceptance, compliance, and achievement of seroprotection.

RESULTS

Thirteen (8%) patients had been immunized previously and had antibodies, whereas 8 (5%) patients had serologic evidence of a previous infection. Of the 136 patients eligible for the study, 113 (83%) agreed to participate, 16 (12%) declined, and 7 (5%) moved away from New York right after delivery. Of the 113 participants, 104 (92%) patients received at least 2 vaccine injections, with 80 (71%) completing 3 injections. Among patients who had postvaccinal antibody titers, 66 of 69 (96%) of the group that received 3 injections and 9 (75%) of 12 of the group that received 2 injections were found to have antibodies.

CONCLUSION

Hepatitis B immunization in the postpartum period is feasible and effective.
