Tuberculosis infection control knowledge and attitudes among health workers in Uganda: a cross-sectional study

Valuation of knowledge, attitude, practices of tuberculosis among the health care workers from Islamabad Pakistan

BACKGROUND

Tuberculosis (TB) as a foremost infectious disease adds massive burden to morbidity and mortality rate, despite of well-structured TB control programs around the globe. Inappropriate health care management system and poor implementation on standard in relevance to TB, remain some reasons causative to TB prevalence and its rising antimicrobial resistance. Health Care Workers (HCWs) laboring as a part of TB control system, are the vital warriors in achieving the goals of TB End Strategy by 2035. Their performance is influenced by their knowledge, attitude, and practices (KAP) toward this infectious disease. This study aimed to signify the role of KAP score of health care Workers in the better control and prevention of TB in the Islamabad Capital Territory (ICT), Pakistan.

METHODS

A cross-sectional study on Knowledge, Attitude and Practice study of Tuberculosis (TB) among health care Workers, was done in ICT, which is the capital of Pakistan. The KAP of TB was collected for the 306 Health Care Workers from all the Islamabad TB referring health facilities which refer the TB patients for testing to the National Reference Laboratory, Islamabad Pakistan. Eligible health care workers were requested to respond on KAP questionnaire after informed consent. KAP questionnaire comprised of knowledge, attitude, and practices section including demographic information. All the data was analyzed using IBM SPSS statistics 21. One Way Analysis of Variance (ANOVA) was applied to calculate KAP mean score against different variables. On the significant data sets of ANOVA output, Tukey's Multiple Comparison Test was applied for pairwise comparison. Pearson correlation coefficient was utilized to explore the association between two qualitative variables. The non-parametric tests were applied to evaluate difference of KAP score in relation to demographic covariates individually.

RESULTS

From June to July 2023, we conducted TB KAP study among Health Care Workers of ICT, Pakistan. The average age was 33 years (range 26-30 years). Majority of the recruited subjects were not being trained for dealing with TB infection. The results demonstrated that Health Care Workers working were lacking their knowledge about mode of TB transmission, best diagnostic technique, and contraction of TB infections. The mean knowledge, attitude and practices mean scores were 15.05 (SD = 3.96), 83.68 (SD = 15.74) and 6.31 (SD = 2.21), respectively. Mean knowledge score of Health Care Workers were significantly related to their educational level and occupation while no significant association was declared with working experience as TB staff. Pearson coefficient of attitude score with knowledge of Health Care Workers was of weak level (0.28). Practice mean score was correlated to knowledge mean score at a moderate level (r = 0.40). On the other hand, practice score was r = 0.29 with attitude mean score had shown weak level correlation. A number of demographic factors were strongly linked to each of the mean score of knowledge, attitude, and practices.

CONCLUSION

These findings highlighted the significant involvement of education, profession, and professional trainings in the better knowledge, attitude, and practices of the TB related health care Workers. For a better management system of infectious diseases like TB, a well-trained and professionally competent staff of Health Care Workers is important so as to achieve the goal of TB-End strategy by 2035 from Pakistan, which is the 5th highest burden country for TB.

Evaluating tuberculosis knowledge and awareness of effective control practices among health care workers in primary- and secondary-level medical institutions in Beijing, China

OBJECTIVE

Inadequate tuberculosis (TB) knowledge and awareness of proper TB control practices among health care workers (HCWs) may increase the risk of nosocomial TB transmission. This study aimed to assess HCWs' TB-related knowledge and control practices to guide the development of more effective targeted TB health education and training programs.

METHODS

In January 2023 a cross-sectional survey was administered to 323 HCWs employed by five primary health care centers and three secondary comprehensive medical institutions in Beijing, China. Survey data were collected using a standard questionnaire.

RESULTS

Analysis of survey responses revealed TB knowledge and practices awareness rates of 60.4% and 90.6%, respectively. The overall average awareness rate across all 19 TB knowledge- and practice-related questions was 70.0%. Intermediate- and senior-level HCW's average TB knowledge score was respectively 2.225 and 8.175 times higher than that of primary-level HCWs, while the average TB knowledge score of HCWs in secondary comprehensive medical institutions was 3.052 times higher than that of HCWs in primary health care centers. Higher average TB knowledge score correlated with higher-level professional titles and higher level work units, but higher average TB control practices score correlated with employment at primary health care center rather than secondary comprehensive medical institution. Notably, 13.6% of HCWs had not received TB training during the past three years, while 86.1% expressed willingness to undergo online TB training.

CONCLUSION

These findings highlight inadequate TB knowledge and awareness of proper TB control practices among HCWs in primary health care centers and secondary comprehensive medical institutions in Beijing, underscoring the urgent need for targeted educational and training initiatives to improve TB awareness and control efforts.

Knowledge and Practices toward Tuberculosis Case Identification among Accredited Drug Dispensing Outlets Dispensers in Magu District, Northwestern Tanzania

Accredited Drug Dispensing Outlets dispensers (ADDO dispensers) have a crucial role in detecting and referring TB suspects. However, several studies highlight low knowledge of TB among ADDO dispensers. To facilitate this, the National TB and Leprosy Control Program trained ADDO dispensers on case identification and referral. Hence, this was a community-based cross-sectional study to determine the knowledge and practice of ADDO dispensers in the detection of active tuberculosis suspects in Magu Districts, Mwanza, Tanzania. This was a cross-sectional study that included 133 systematically selected ADDO dispensers. Out of 133 ADDO dispensers, 88 (66.9%) had attended TB training. About 108 (81%) participants had good knowledge of TB. The majority of ADDO dispensers 104 (78.4%) had poor practice toward the identification of TB cases. Attending training (AOR 4.49, CI 1.03-19.47), longer working experience (AOR 4.64, CI 1.99-10.81), and the presence of national TB guidelines (AOR 3.85, CI 1.11-13.34) was significantly associated with good self-reported TB case identification practices. Therefore, the study revealed adequate knowledge but with poor practice. Provisions to train ADDO dispensers in tuberculosis case detection and referral could yield great results.

Influencing Factors of Treatment Outcomes Among Patients with Pulmonary Tuberculosis: A Structural Equation Model Approach

BACKGROUND

Pulmonary tuberculosis (PTB) is a serious infectious disease, and the factors and pathways that influence final treatment outcomes are unclear. Here, we aimed to assess the factors that influence treatment outcomes in patients with PTB using a structural equation model.

METHODS

Participants completed a questionnaire covering demographics, understanding of PTB, psychological status, and history of medical treatment. Exploratory factor analysis and reliability testing were performed, and a structural equation model was constructed using the SPSS and Amos software.

RESULTS

A total of 251 participants were enrolled. Symptoms of depression were observed in 94.4% of participants, whereas 6% showed mild or greater anxiety. Through factor rotation, four common factors were extracted with a total variation of 66.15%. The structural equation model indicated that regular tuberculosis-related follow-up behaviour had a direct and positive effect on the final treatment outcome, with a path coefficient value of 0.20; the level of PTB understanding had a direct positive effect on the testing behaviour for PTB, with a path coefficient of 0.26; patients' psychological characteristics had a direct negative impact on regular testing behaviour, with a path coefficient of -0.13. The psychological characteristics and level of disease understanding of patients exerted indirect effects on the treatment outcome by affecting the way patients approached tuberculosis detection behaviour.

CONCLUSION

Interventions aimed at improving the treatment outcomes of patients with PTB should mainly focus on financial support and improvements in psychological status in addition to a greater understanding and knowledge of PTB. Furthermore, patients should be encouraged to undergo regular PTB testing during the follow up period, as this mediates the effect of other factors on treatment outcomes and also helps in achieving favourable treatment outcomes.

A machine learning approach to explore individual risk factors for tuberculosis treatment non-adherence in Mukono district

Despite the availability and implementation of well-known efficacious interventions for tuberculosis treatment by the Ministry of Health, Uganda (MoH), treatment non-adherence persists. Moreover, identifying a specific tuberculosis patient at risk of treatment non-adherence is still a challenge. Thus, this retrospective study, based on a record review of 838 tuberculosis patients enrolled in six health facilities, presents, and discusses a machine learning approach to explore the individual risk factors predictive of tuberculosis treatment non-adherence in the Mukono district, Uganda. Five classification machine learning algorithms, logistic regression (LR), artificial neural networks (ANN), support vector machines (SVM), random forest (RF), and AdaBoost were trained, and evaluated by computing their accuracy, F1 score, precision, recall, and the area under the receiver operating curve (AUC) through the aid of a confusion matrix. Of the five developed and evaluated algorithms, SVM (91.28%) had the highest accuracy (AdaBoost, 91.05% performed better than SVM when AUC is considered as evaluation parameter). Looking at all five evaluation parameters globally, AdaBoost is quite on par with SVM. Individual risk factors predictive of non-adherence included tuberculosis type, GeneXpert results, sub-country, antiretroviral status, contacts below 5 years, health facility ownership, sputum test results at 2 months, treatment supporter, cotrimoxazole preventive therapy (CPT) dapsone status, risk group, patient age, gender, middle and upper arm circumference, referral, positive sputum test at 5 and 6 months. Therefore, machine learning techniques, specifically classification types, can identify patient factors predictive of treatment non-adherence and accurately differentiate between adherent and non-adherent patients. Thus, tuberculosis program management should consider adopting the classification machine learning techniques evaluated in this study as a screening tool for identifying and targeting suited interventions to these patients.

Improving Nurses' Knowledge, Practice, and Self-Efficacy Regarding Caring Patients with Tuberculosis: A Quasi-Experimental Design

Background

Tuberculosis (TB) control depends on healthcare professionals 'knowledge, practice, and self-efficacy when managing high-risk groups. So the study aimed to evaluate the effectiveness of a structured educational program in improving nurses' knowledge, practice, and self-efficacy in caring for patients with TB.

Material and Methods

A pre-test post-test quasi-experimental design was conducted on 36 nurses at Chest hospital Al Masah al Bahri in port said city and the Chest Hospital in Damietta City, Egypt. Data were collected using three self-administered questionnaires to assess knowledge, practice, and self-efficacy by using convenience sampling from March to August 2019. Data analyses were done by using a paired t-test, a Student t-test, and an F-test analysis of variance.

Results

Based on data related to the two groups before and after the study in knowledge, practice (t = 8.27, p < 0.001), and self-efficacy (t = 28.91, p < 0.001), there was a significant difference between knowledge and overall knowledge scores (t=14, p < 0.001). Mean scores were significantly increased for practice items about the nursing role in medication, directed observed therapy, and the overall practice score; and for self-efficacy, which increased from 27.58 to 37.86 (p = <0.001). The results indicate that nurses' knowledge, practice, and self-efficacy were enhanced by the implementation of the educational program.

Conclusions

There is scope for development in knowledge, practice, and self-efficacy using the educational program among nurses. Training programs must be implemented in quality control to aid nurses in realizing the significance of information in reducing disease and death and enhancing the quality of care.

Non-tuberculous mycobacterial pulmonary disease: Awareness survey of front-desk healthcare workers in Northern Tanzania

Over the past decade, there have been increasing reports of non-tuberculous mycobacteria (NTM) species being implicated in tuberculosis (TB) treatment failure or misdiagnosed as TB. Inadequate awareness of NTM pulmonary disease among healthcare workers (HCWs) may contribute to a low index of suspicion for patients presenting to their hospitals. In this study, we assessed the awareness of NTM pulmonary disease (NTM-PD) among front desk HCWs in Northern Tanzania. A cross-sectional descriptive survey was carried out among front desk HCWs in four administrative regions of Northern Tanzania. A standardized questionnaire was administered to consented participants from four clusters; clinicians, laboratory scientists, nurses, and pharmacists serving TB patients from Regional and District Health Facilities. Each participant was asked a set of questions, scored and the total score for each participant was determined. An awareness score was used to measure the level of awareness. The average score for all participants was estimated including the 95% confidence interval (CI). The overall awareness score was 24.1%, 95% CI 22.0-26.2%. History of training, experience in TB care, level of health facilities, age group, and setting were found to be statistically associated with the level of awareness of study participants. More than two-thirds (67%) of participants believe that pulmonary NTM and TB are clinically similar and 60% are not aware that AFB Microscopy cannot distinguish between the two. Only 13% of participants could mention at least one risk factor for NTM pulmonary disease. The level of awareness of NTM pulmonary disease was poor among HCWs in the surveyed TB clinics. National TB Programs are advised to include a topic on NTM in various on-job TB training packages for HCWs.

Attitudes of Healthcare Workers about Prevention and Control of Nosocomial Multidrug-Resistant Tuberculosis Infection in Two Top-Ranked Tuberculosis Specialized Public Hospitals of Ethiopia

Background

Tuberculosis (TB) exists as a human curse since antiquity. Around 9.5 million cases and 1.5 million deaths were reported due to TB in 2021. Ethiopia is one of the high-burdenmultidrug-resistant (MDR) TB countries. MDR-TB is acquired either by poor adherence to treatment or by primary infection with a drug-resistant strain, which has a high transmission rate from patients to healthcare workers (HCWs). Hospital outbreaks of MDR-TB are common in Africa. Hence, this study aimed to score the attitude of HCWs working in the two nationally top-rankedTB-specialized hospitals in Ethiopia, Saint Peter's and ALERT TB-specialized public hospitals about the infection prevention and control (IPC) of nosocomial MDR-TB.

Methods

A cross-sectional study was conducted from December 1, 2020, to March 31, 2021. A simple random sampling method was applied to select 384 HCWs. The data collection tool was a self-administered interview structured questionnaire. The data were analyzed using SPSS software. Descriptive statistics were applied to score attitude. Bivariate and multivariable logistic regression models were performed to identify the independent determinants of attitude. The odds ratio was used to test the degree of association between variables at a 95% confidence interval (CI). The level of statistical significance was fixed at p value < 0.05.

Results

Among the respondents, 87% of the HCWs held favourable attitudes about the nosocomial MDR-TB-IPC. The favourable attitude score had a significant association with the monthly salary earned between 7001 and 9000 ETB (Ethiopian Birr) (AOR = 3.34, 95% CI: 1.11, 10.05) and the previous training obtained on TB/MDR-TB (AOR = 2.96, 95% CI: 1.32, 6.62).

Conclusions

Almost one in seven HCWs has an unfavourable attitude. Prior training received and earning monthly income above 7000 ETB are independent determinants of a favourable attitude score. Refreshment training and a reasonable increment in monthly income should be strengthened in TB-specialized hospitals in Ethiopia.

Knowledge and Practice on Prevention and Control of Tuberculosis Among Nurses Working in a Regional Hospital, Nepal

Introduction

Tuberculosis (TB) is a highly prevalent communicable disease in Nepal. All health personnel who care for such patients are at high risk of developing tuberculosis. It is very necessary for all healthcare providers, especially nurses, who spend a lot of time with such patients, to have adequate knowledge and correct practice on the occupational safety measures to maintain health and prevent transmission of the disease. This study was carried out to assess the knowledge and practice of nurses in the prevention and control of TB infection.

Method

This study was a cross-sectional study conducted on nurses working in all wards and Outpatient Departments (OPDs) of Western Regional Hospital, Pokhara, Nepal. A complete enumeration of the respondents was performed, and data were collected consecutively, using a semi-structured self-administered questionnaire, from all nurses working in all the wards and OPDs of the hospital. The predictors of knowledge of TB infection prevention and control (TBIPC) were assessed using binary logistic regression.

Results

The study findings showed that a majority of nurses had an inadequate level of knowledge and poor practice of prevention and control of TB. Regarding practice, none of the nurses reported the use of an N95 mask or a respirator during care of the patients with TB and all the nurses reported that they used chemical disinfectant (virex) to clean the room and the surfaces. However, none of them reported the use of fumigation or ultraviolet irradiation for disinfection. Nurses who were 40 years and older (p = 0.001, adjusted odds ratio (AOR) = 5.965, CI = 2.083–17.457) and who were currently working in the wards with isolation rooms demonstrated higher odds for knowledge on TBIPC (p = 0.010, AOR = 2.686, CI = 1.264–5.710).

Conclusions

This study showed that a majority of nurses had an inadequate level of knowledge and implemented poor safety measures for the prevention and control of tuberculosis. This increases their risk of being infected with TB infection and cross-transmission. It is recommended that the hospital plan and conduct the necessary education/training for nurses to update their knowledge, develop the organizational structure and policies, and establish a system to support and monitor the practice of health workers on the prevention and control of TB, and maintain the health and safety of nurses caring for patients with TB.

The relationship among social support, experienced stigma, psychological distress, and quality of life among tuberculosis patients in China

The complex relationships among social support, experienced stigma, psychological distress, and quality of life (QOL) among tuberculosis (TB) patients are insufficiently understood. The purpose of this study was to explore the interrelationships among social support, experienced stigma, psychological distress, and QOL and to examine whether experienced stigma and psychological distress play a mediating role. A cross-sectional survey was conducted between November 2020 and March 2021 in Dalian, Liaoning Province, Northeast China. Data were obtained from 473 TB patients using a structured questionnaire. Structural equation modelling was used to examine the hypothetical model. The research model provided a good fit to the measured data. All research hypotheses were supported: (1) social support, experienced stigma and psychological distress were associated with QOL; (2) experienced stigma fully mediated the effect of social support on psychological distress; (3) psychological distress fully mediated the effect of experienced stigma on QOL; and (4) experienced stigma and psychological distress were sequential mediators between social support and QOL. This study elucidated the pathways linking social support, experienced stigma, and psychological distress to QOL and provides an empirical basis for improving the QOL of TB patients.

Barriers and Motivators of private hospitals' engagement in Tuberculosis care in Uganda

INTRODUCTION

The involvement of private hospitals in Tuberculosis care in Uganda is still limited. There is a lack of literature about the barriers and motivators to private hospitals' engagement in Tuberculosis care in Uganda.

OBJECTIVE

To explore the barriers to and motivators of private hospitals' engagement in Tuberculosis care.

METHODS

The study employed a qualitative study design that utilized in-depth interviews with 13 private healthcare workers purposively selected in June 2020 due to their active involvement in Tuberculosis care from four urban private hospitals in Mbarara Municipality. An inductive, content analytic approach framed by the Consolidated Framework for Implementation Research, was used for analysis. The interviews were transcribed and coded to identify key themes using content analysis.

RESULTS

Focusing through the Consolidated Framework for Implementation Research, barriers to private hospitals' engagement were related to cost, external policies and incentives, structure characteristics, networks and communications, and knowledge and beliefs about the intervention. These include concerns regarding the payment of care by patients; indirect income-generating nature of Tuberculosis management; lack of drugs, registers, and diagnostic tools; lack of accreditation from the Ugandan Ministry of Health; limited space for keeping Tuberculosis patients; lack of proper follow-up mechanism; lack of training and qualified human resources; and delayed seeking of health care by the patients. Perceived high quality of care in the private hospitals; privacy and confidentiality concerns; proximity of private hospitals to patients; and formalization of partnerships between private hospitals and the government were the motivators that arose from the three constructs (relative advantage, patient needs, and resources, and engaging).

CONCLUSION

The engagement of private hospitals in Tuberculosis care requires commitment from key stakeholders supplemented with the organizational shared beliefs towards this change. There is a need for ensuring mechanisms for lessening these barriers to ensure full engagement of private hospitals in Tuberculosis care.

Knowledge, attitudes and practices regarding tuberculosis amongst healthcare workers in Moyen-Ogooué Province, Gabon

Background

In countries with a high tuberculosis incidence such as Gabon, healthcare workers are at enhanced risk to become infected with tuberculosis due to their occupational exposure. In addition, transmission can occur between patients and visitors, if a tuberculosis infection is not suspected in time. Knowledge about tuberculosis and correct infection control measures are therefore highly relevant in healthcare settings.

Methods

We conducted an interviewer-administered knowledge, attitude and practice survey amongst healthcare workers in 20 healthcare facilities at all levels in the Moyen-Ogooué province, Gabon. Correctly answered knowledge questions were scored and then categorised into four knowledge levels. Additionally, factors associated with high knowledge levels were identified. Fisher’s Exact test was used to identify factors associated with high knowledge levels.

Results

A total of 103 questionnaires were completed by various healthcare personnel. The most-frequently scored category was ‘intermediate knowledge’, which was scored by 40.8% (42/103), followed by ‘good knowledge’ with 28.2% (29/103) and ‘poor knowledge’ with 21.4% (22/103) of participating healthcare workers, respectively. ‘Excellent knowledge’ was achieved by 9.7% (10/103) of the interviewees. Apart from the profession, education level, type of employing healthcare facility, as well as former training on tuberculosis were significantly associated with high knowledge scores.

Attitudes were generally positive towards tuberculosis infection control efforts. Of note, healthcare workers reported that infection control measures were not consistently practiced; 72.8% (75/103) of the participants were scared of becoming infected with tuberculosis, and 98.1% saw a need for improvement of local tuberculosis control.

Conclusions

The survey results lead to the assumption that healthcare workers in the Moyen-Ogooué province are at high risk to become infected with tuberculosis. There is an urgent need for improvement of tuberculosis infection control training for local healthcare personnel, particularly for less trained staff such as assistant nurses. Furthermore, the lack of adequate infection control measures reported by staff could possibly be correlated with a lack of adequate facility structures and protective equipment and requires further investigation.

Health professionals' knowledge and attitude of tuberculosis infection control in Mizan Tepi University Teaching Hospital, Ethiopia

Background

Health professionals are the front-line agents to realize tuberculosis (TB) Infection Control (TBIC) in health facilities and in turn to achieve the targets of the End TB strategy. Despite this, evidence on their knowledge and attitude regarding TBIC is inadequate. As a result, this study aimed to investigate the knowledge and attitude of health professionals regarding TBIC, and associated factors in Mizan Tepi University Teaching hospital.

Methods

An institution-based cross-sectional study was conducted from September 1 to 30, 2019 by including eligible health professionals in the hospital. Knowledge and attitude of TBIC were the outcome variables. We have used 70% as a cut-off to categorize the knowledge and attitude statuses. Binary logistic regression was used to identify factors associated with the outcome variables. The odds ratio with its respective 95% confidence interval was used to measure the strength of association. The final significance was declared at a p-value of<0.05.

Results

The study found that 70.2% (95%CI: 63.8%, 76.6%) and 78.3% (95% CI: 72.3%, 84%) of the respondents had good knowledge and positive attitude regarding TBIC respectively. The current profession, job location, and history of TBIC training were significantly associated with the respondents' knowledge. Whereas, the knowledge status of the respondents was the only significant predictor of the attitude.

Conclusion

Although our study participants had satisfactory knowledge and attitude regarding TBIC to some extent, it needs due attention to achieve the target of End TB strategy. Thus, updating the health professionals through different skill-based TBIC training should be considered.

Service years of health professionals are associated with tuberculosis infection control practice in Ethiopian Teaching Hospital

Introduction

proper tuberculosis (TB) infection control (TBIC) practice of health professionals is one of the effective TB prevention approaches. Despite this reality, the TBIC practice of health care workers was not been well studied. This study assessed the TBIC practice of health professionals and associated factors in Mizan Tepi University Teaching Hospital, southwest Ethiopia.

Methods

an institution based quantitative cross-sectional study was conducted from September 1 to 30, 2019, by including all health professionals in the hospital. Participants who answered at least 50% of TBIC practice questions correctly were categorized as having good TBIC practice. Binary logistic regression was used to identify factors associated with the practice of the participants. The odds ratio with a 95% confidence interval and p-value was used to measure the strength of association; the significant association was declared at a p-value less than 0.05.

Results

the study found that 64.1% (95% CI: 56.6%, 70.7%) of the participants had good TBIC practice. More than half, 102(51.5 %) of study participants have service years of greater than or equal to five years. Only the service year of health professionals was significantly associated [95%CI (AOR= 2.43; 95%CI: 1.28, 4.6)] with the respondents´ TBIC practice.

Conclusion

only less than two-third of health professionals had good TBIC practice which is inadequate. And also experienced staff had significantly better TBIC practice. As a result, health professionals in MTUTH should be supported to practice TBIC as routine activity and opportunities should be made for senior staffs to share their TBIC experiences with others.

EFFECT OF TRAINING ON KNOWLEDGE AND ATTITUDE TO STANDARD PRECAUTION AMONG WORKERS EXPOSED TO BODY FLUIDS IN A TERTIARY INSTITUTION IN SOUTH-WEST NIGERIA

INTRODUCTION

Standard precaution in the workplace reduces the risk of occupational hazards among workers exposed to body fluids of humans and animals. Training on standard precaution has been recommended as a strategy to improve knowledge, attitude and compliance to these guidelines. This study therefore determine the effect of training on knowledge and attitude to standard precaution among workers exposed to body fluids of humans and animals in the University of Ibadan, South-west, Nigeria.

METHODS

This was an interventional study among workers exposed to body fluids of humans and animals. A total survey of all faculties where staff and student come in contact with human and animal body fluid was done. Selected staff were trained for two days on standard precaution. A self-administered questionnaire was used to obtain information on socio-demographic information, knowledge and perception of staff on standard precaution. The maximum obtainable knowledge and attitude scores were 27 and 6 points respectively. The mean knowledge and attitude score were determined at pre-test and post-test. Frequency, proportion, mean and standard deviation were used for summary statistics and an independent t-test was performed to test for association. Statistical significance was set at 5%.

RESULTS

A total of 136 and 123 responses were obtained at pre-test and posttest respectively. A little over half of the respondents were females (51.5%) and below 40 years (54.4%). The mean knowledge score among the workers increased from 22.59 ± 3.4 at pre-test to 22.83 ± 3.2 at post-test, but it was not statistically significant. However, the mean post-test attitude score (5.10 ± 1.4) was significantly different from the pre-test attitude score (4.49 ± 1.5).

CONCLUSION

Training improved the knowledge and attitude of workers exposed to body fluids of humans and animals working in the University of Ibadan on standard precaution. Periodic training on standard precaution is therefore recommended to sustain a proper attitude to standard precaution guidelines.

The effect of an educational intervention to improve tuberculosis infection control among nurses in Ibadan, south-west Nigeria: a quasi-experimental study

Background

Nurses are particularly vulnerable to acquiring tuberculosis (TB) because they are in the frontline of patient care. There is inadequate implementation of cost-effective TB infection control (TBIC) measures in most health facilities. Training has been shown to be effective in improving the knowledge and work practices of nurses. This study sought to utilize a multi-method educational intervention to improve the TBIC-related knowledge and practices of nurses in two secondary health facilities in Ibadan, South-West Nigeria.

Methods

This quasi-experimental study involved 200 nurses (100 each in the intervention and comparison groups). Baseline data were collected in May 2014. This was followed by training of the nurses in the intervention group. After 6 months, the second wave of data was collected and the nurses in the comparison group also received the training thereafter. The final wave of data collection took place 12 months after the commencement of the study. The mean scores of the nurses were determined and comparison was made between both groups at different time points using independent t-test.

Results

The nurses in both groups were statistically comparable in their socio-demographic characteristics, and baseline mean knowledge (68.6 and 67.7%) and practice scores (79.1 and 80.6%) respectively. After the intervention group received the intervention, there were appreciable improvements in the scores at 6 months (knowledge – 85.9%, practice – 98.5%), which were significantly different from those of the comparison group (knowledge – 69.5%, practice – 78.8%). A large effect size was demonstrated in the improvement in knowledge score in the intervention group at 6 months compared with the other group (Cohen’s d = 1.7). Similarly, there were improvements in the scores of the nurses in the comparison group at 12 months after the group had also received the intervention (knowledge – 88.2%, practice – 93.5%). At this point, the mean scores between both groups were no longer significantly different.

Conclusions

The improvement in post-intervention scores implies that the educational intervention adopted for this study was effective in improving TBIC among the nurses. It also underscores the importance of continuous training/retraining of nurses and other healthcare workers in improving and sustaining TBIC at health facilities.

Knowledge and practices regarding tuberculosis infection control among nurses in Ibadan, south-west Nigeria: a cross-sectional study

BACKGROUND

Nurses are particularly vulnerable to nosocomial tuberculosis (TB) infection because, being in the frontline of healthcare provision, they are frequently exposed to patients with infectious TB disease. Although cost-effective measures are available for TB infection control (TBIC), they are often poorly implemented. Knowledge of TBIC is known to positively influence the practice of the measures. There is, however, paucity of data on the knowledge and practices regarding TBIC among nurses in Nigeria. This study was aimed at determining the levels of TBIC-related knowledge and practices of nurses in Ibadan, and their associated socio-demographic factors.

METHODS

This cross-sectional study utilized a self-administered questionnaire to collect data from 200 nurses in two secondary health facilities, in May 2014. The mean knowledge and practice scores of the nurses were determined and logistic regression was utilized to explore the association between the scores and socio-demographic characteristics.

RESULTS

The respondents had mean knowledge and practice scores of 68.2 and 79.9% respectively. Using cut-off points of 80 and 100% for good knowledge and practice scores respectively, small proportions of the nurses had good scores - knowledge (10.5%) and practice (6%). Knowledge was not significantly associated with the socio-demographic characteristics of the nurses. Work experience was the only factor that was significantly associated with practices, with the more experienced nurses (> 18 years of work experience) having lower odds of obtaining good practice scores (OR 0.25, 95% CI 0.06-0.94). There was also no significant association between knowledge and practice scores (the nurses were yet to be trained on the newly-introduced TBIC package at the time of the study).

CONCLUSIONS

The study revealed that small proportions of the nurses had good knowledge and practice scores. Its findings will be useful for the designing of interventions to improve TBIC among nurses and other healthcare workers, and to benchmark evaluation of the interventions. It is recommended that nurses should be trained on TBIC to equip them with necessary knowledge and skills. This, together with appropriate policy directives, and adequate monitoring and supervision will contribute to optimal implementation of TB preventive measures.

The Global call for action on infection prevention and control

PURPOSE

Healthcare-associated infections (HAIs) constitute a major threat to patient safety and affect hundreds of millions of people worldwide. The World Health Organization in 2016 published guidelines on the core components for infection prevention and control (IPC) programme. This was in response to a global call for focused action. The purpose of this paper is to examine and promote understanding of the tenets of the IPC guidelines and highlight their implications for implementation in low-income countries.

DESIGN/METHODOLOGY/APPROACH

Drawing from personal experiences in leading the implementation of health programmes as well as a review of published and grey literature on IPC, authors discussed and proposed practical approaches to implement IPC priorities in low-income setting.

FINDINGS

Availability of locally generated evidence is paramount to guide strengthening leadership and institutionalisation of IPC programmes. Preventing infections is everybody's responsibility and should be viewed as such and accorded the required attention.

ORIGINALITY/VALUE

Drawing from recent experiences from disease outbreaks and given the heavy burden of HAIs especially in low-income settings, this paper highlights practical approaches to guide implementation of the major components of IPC.

Risk factors of tuberculosis infection among health care workers: A meta-analysis

BACKGROUNDS

Health care workers (HCWs) are globally known to have high risk of tuberculosis (TB) infection while risk factors of TB infections among HCWs are still inconclusive.

OBJECTIVES

To perform a meta-analysis in effort to identify risk factors of TB infection among HCWs.

METHODS

A meta-analysis was conducted between February and July 2019. Papers were searched in Pubmed, Embase, Cochrane, and Web of science and information of interest were extracted. The correlation and effect estimation were analyzed using random or fixed effect model.

RESULTS

A total of 12 studies consisting of 2871 cases and 15,673 controls were included and six risk factors were available for meta-analysis. Cumulative calculation found that age, working duration, and types of job were significant risk factor of TB infection while gender, active TB contact, and types of workplace were not associated significantly with TB infection among HCWs. Our pooled data revealed that decreased risk of TB infection was observed in age less than 30 years (age < 30 years vs. age ≥ 30 years) and working duration less than five years (working duration < 5 years vs. ≥5 years). Being more than 40 years, working more than 10 years, and being physicians increased the risk of TB infection significantly compared to age ≤40 years, working duration ≤10 years, and other job types, respectively.

CONCLUSIONS

Our meta-analysis has identified the significant risk factors of TB infection among HCWs. Our results may be useful for establishing future TB prevention program among HCWs.

The role of tuberculosis control institutes in delivering tuberculosis information to domestic migrants in China: A multi-level analysis of a nationwide cross-sectional survey

OBJECTIVES

The aim of this study was to understand how tuberculosis (TB) control institutes raise awareness of TB among domestic migrants in China, specifically whether migrants have received TB information and how they received it.

METHODS

This multi-level analysis included both county-level data and individual-level data covering 31 provinces in mainland China. Multi-level logistic models were used to explore the factors associated with receiving TB information.

RESULTS

This analysis included 205 990 migrants from 31 provinces and municipalities. Only 77 460 (37.60%) migrants reportedly received any TB information in mainland China. The center for disease control and prevention (CDC), the center for tuberculosis control (CTC), and the center for prevention and treatment of chronic diseases (CPTCD) were the most likely to provide TB information for migrants in comparison to other types of TB control institutes, such as general hospitals, specialized hospitals, and community healthcare centers. The odds ratios were calculated as: 1.563 (95% confidence interval (CI) 1.246-1.959) for CDCs, 1.385 (95% CI 1.063-1.804) for CTCs, and 1.723 (95% CI 1.424-2.085) for CPTCDs.

CONCLUSIONS

China has not achieved universal coverage of TB awareness. TB awareness levels are higher in regions with CDC, CTC, and CPTCD institutes. Domestic migrants who have moved to western areas are more likely to have received TB information.

Tuberculosis knowledge, attitude and practice among healthcare workers during the 2016 Hajj

BACKGROUND

Given the inherent characteristics of the Hajj pilgrimage, the event is a risk for tuberculosis (TB) infection. Early diagnosis and appropriate management of TB cases by knowledgeable and skilled healthcare workers (HCWs) are key in improving patients' outcome and preventing transmission during the Hajj mass gathering and globally.

METHOD

We conducted a cross-sectional study to assess knowledge, attitude and practice (KAP) of HCWs deployed during the 2016 Hajj regarding TB and its management using an anonymous self-administered questionnaire.

RESULTS

Data was collected from 540 HCWs from 13 hospitals. HCWs originated from 17 countries and included physicians, nurses and other non-administrative HCWs. Nearly half of HCWs declared having experience dealing with TB patients. In general, HCWs had average knowledge (mean knowledge score of 52%), above average attitude (mean attitude score of 73%) and good practice (mean practice score of 85%) regarding TB, based on our scoring system and cut-off points. Knowledge gaps were identified in relation to the definition of MDR-/XDR-TB and LTBI, smear microscopy results, length of standard TB treatment for drug-sensitive TB, 2nd line anti-TB drugs, BCG vaccination, and appropriate PPE to be used with active PTB patients. Poor attitudes were found in relation to willingness to work in TB clinic/ward and to the management and treatment of TB patients. Poor practices were reported for commencing anti-TB treatment on suspected TB cases before laboratory confirmation and not increasing natural ventilation in TB patients' rooms. Age, gender, nationality, occupation, length of work experience and experience dealing with TB patients were associated with knowledge scores. Age and occupation were associated with attitude scores while length of work experience and occupation were associated with practice scores. There was a weak but statistically significant positive correlation between score for knowledge and attitude (rs = 0.11, p = 0.009) and attitude and practice (rs = 0.13, p = 0.002).

CONCLUSIONS

While the results of the study are encouraging, important knowledge gaps and some poor attitudes and practices regarding TB were identified among HCWs during Hajj. This calls for multifaceted interventions to improve HCWs KAP regarding TB including tailored, periodic TB education and training aimed at boosting knowledge and improving behaviour.

The Mediating Effects of Stigma on Depressive Symptoms in Patients With Tuberculosis: A Structural Equation Modeling Approach

Objectives: To date, the complex interrelationships between family function, doctor-patient communication, knowledge about tuberculosis (TB), stigma, and depressive symptoms among patients with TB are insufficiently understood. We explored the interrelationships between family function, doctor-patient communication, knowledge about TB, TB-related stigma, and depressive symptoms and examined whether TB-related stigma played a mediating role. Methods: A cross-sectional survey was conducted between October 1, 2013 and March 31, 2014 in Hubei province, central China. Data were collected from 1,309 patients with TB using a structured questionnaire that measured family function, doctor-patient communication, knowledge about TB, stigma, and depressive symptoms. Structural equation modeling was used to examine the interrelationships among the study variables based on the hypothesized model. Results: The proposed model provided a good fit to the obtained data. There were indirect effects between family function, doctor-patient communication, knowledge about TB, and depressive symptoms through stigma (β = -0.048, P = 0.002; β = -0.028, P = 0.001; β = -0.021, P = 0.009, respectively). Stigma partially mediated the effect of family function and knowledge about TB on depressive symptoms and fully mediated the effect of doctor-patient communication on depressive symptoms. Conclusions: This study elucidated the pathways linking family function, doctor-patient communication, and knowledge about TB to depressive symptoms and confirmed that the effect of those variables on depressive symptoms can be mediated by stigma. Those findings provide direction and information for depression interventions among patients with TB.
