Tuberculosis: a health education imperative returns

The effect of health education on knowledge and behavior toward respiratory infectious diseases among students in Gansu, China: a quasi-natural experiment

BACKGROUND

The respiratory infectious diseases (RID) threaten the health and life quality of school students. However, previous related studies were insufficient in research design and method applied. This study aimed to evaluate the effect of health education on the knowledge and behavior of students toward RID through difference-in-difference (DID) analysis in Gansu, China.

METHODS

In 2015-2016, a one-year health education program in Gansu, China was conducted. The intervention group contained 1064 students before and 1001 students after the health education (2015 and 2016, respectively). The control group contained 1018 and 1001 students, respectively. The health education, including playing promotional cartoons, developing lectures, giving out handbook copies and making hand copy and blackboard newspapers, and publicity columns on RID, were conducted monthly from 2015 to 2016 in intervention group. The data were collected before and after the health education program with a questionnaire on the students' knowledge and preventive behaviors regarding RID. The ×2 and t tests were performed to compare the accuracy rate and scores for RID knowledge and behavior of the two groups. DID estimation was conducted to evaluate the effect of health education on RID knowledge and behavior while controlling the non- equilibrium variables.

RESULTS

After the health education program, the accuracy rate and scores of most items in the intervention group were significantly higher than those in the control group (P < 0.05) except for item k9 "What methods can prevent flu?". The DID results wherein the demographics- age, nationality, and household register were controlled showed that health education significantly improved the accuracy rate of RID knowledge by 5.2-63.9% for most items, although the accuracy rates of items k2 "What's the transmission way of the mumps?" and k9 were significantly decreased by 36.8 and 12.0%. The health education significantly improved the score of knowledge by 155.2% (P < 0.001) and the accuracy rate of all items of RID behavior by 2.9-51.5% except for item b3 "If you have phlegm, how do you usually deal with it?". In addition, the health education also significantly improved the score of behavior toward RID of the sampled students by 138.2% (P < 0.001).

CONCLUSION

The results of this study show that health education seemed to increase the RID knowledge and behavior of students. It is recommended that the health education should be enhanced and popularized in schools of China, and RID transmission routes and prevention methods should attract more attention.

Critical reflections on evidence, ethics and effectiveness in the management of tuberculosis: public health and global perspectives

Background

Tuberculosis is a major cause of morbidity and mortality globally. Recent scholarly attention to public health ethics provides an opportunity to analyze several ethical issues raised by the global tuberculosis pandemic.

Discussion

Recently articulated frameworks for public health ethics emphasize the importance of effectiveness in the justification of public health action. This paper critically reviews the relationship between these frameworks and the published evidence of effectiveness of tuberculosis interventions, with a specific focus on the controversies engendered by the endorsement of programs of service delivery that emphasize direct observation of therapy. The role of global economic inequities in perpetuating the tuberculosis pandemic is also discussed.

Summary

Tuberculosis is a complex but well understood disease that raises important ethical challenges for emerging frameworks in public health ethics. The exact role of effectiveness as a criterion for judging the ethics of interventions needs greater discussion and analysis. Emerging frameworks are silent about the economic conditions contributing to the global burden of illness associated with tuberculosis and this requires remediation.

The effect of tuberculosis and tuberculosis contact tracing on school function: an exploratory focus group study

SETTING

Selected schools in East York, an ethnically diverse municipality of 110,000 people within Toronto.

OBJECTIVE

To explore school staff's attitudes and beliefs about the nature of tuberculosis and its possible effect on the function and culture of schools.

DESIGN

Four focus groups of 6-8 school staff, lasting from 1 to 1.5 hours, were held in the spring of 1997 at four different schools deemed to be at high risk for tuberculosis contact tracing.

RESULTS

The study identified the following dominant themes: fear of tuberculosis and its impact on school, lack of knowledge and the need for education concerning tuberculosis, and issues in multiculturalism.

CONCLUSION

Tuberculosis was perceived by staff of East York schools to be a source of fear. Lack of accurate and reliable information concerning tuberculosis contributes to this situation. Staff identified age-specific and culturally relevant, educational initiatives as means to reduce this fear.

Isolation and stigma: the experience of patients with active tuberculosis

Tuberculosis treatment is an important component of community health programs. Understanding how different groups of patients experience tuberculosis can influence the completion of drug therapy. This study explored how a sample of patients with active tuberculosis experienced their illness. Guided by questions from Kleinman's (1980) explanatory model, 28 semistructured interviews were conducted in public health clinics. The analysis suggested that patients understood tuberculosis through the medical model and perceived themselves as disease vectors. After their diagnosis became known, almost all patients felt that their family and friends avoided or shunned them. Patients responded to these attitudes by isolating themselves and becoming secretive about their illness. An awareness of patients' experiences can help nurses to understand behaviors that may be labeled as noncompliant and design interventions that address these behaviors. Modifying community attitudes and behaviors poses a longer term challenge to the elimination of tuberculosis.

Encompassing treatment with prevention: the path for a lasting control of tuberculosis

Tuberculosis is an important cause of death, mainly in the less developed countries. Thus far the strategy for its control had relied on the diagnosis of sick individuals and provision of chemotherapy. However, this strategy is problematic for several reasons: poor education about the disease and the low income of people with tuberculosis are important barriers for them to have access to early diagnosis and to keep adherence to treatment; provision of 'preventive therapy' to the enormous pool of people infected with tuberculosis is not feasible in less developed countries; and finally, long-term political commitment with the strategy is unlikely. Several facts indicate that tuberculosis patterns in different populations are shaped by biological, behavioral and socio-economic factors. This paper argues that a lasting control of tuberculosis requires a strategy based on a broader model of causality, which takes account of all these three causal factors.

Knowledge, Perceptions, and Practice of Nurses Toward HIV+/AIDS Patients Diagnosed With Tuberculosis

BACKGROUND

Tuberculosis (TB) continues to be a major health problem in the United States. Nurses may be exposed to TB and not realize their risks for becoming infected. The presentation of HIV-associated TB is somewhat different from "standard TB."

PURPOSE

The purpose of this study was to determine if an educational program could improve nurses' attitudes, level of knowledge, and compliance with infection control standards for HIV/AIDS patients diagnosed with TB.

METHOD

Participants included 50 staff nurses. The experimental group (35) and control group (15) completed a knowledge test and an attitude survey. Researchers observed participants for compliance with infection control standards pretest and posttest.

RESULTS

Following an educational program, the experimental group demonstrated a greater knowledge of TB than the control group who did not participate in the educational program (F [1.47] = 14.43, p = .000). In addition, the experimental group had a greater improvement in their Nursing Intervention Observation Tool adherence to respiratory isolation and universal precaution protocols scores as compared to the control group (F [1.47] = 8.95, p = .004). However, there was not a tangible increase in knowledge level of AIDS, attitudes or concerns about caring for these patients.

CONCLUSION

This nursing research study supports the need for an ongoing educational program with continual monitoring of infection control practices to positively affect client and caregiver outcomes.
