Evaluation of health-care providers' knowledge of childhood tuberculosis in Lima, Peru

Assessment of professional competencies of Peruvian physicians: A scoping review of published studies

INTRODUCTION

Evaluating the professional competencies of Peruvian doctors is crucial for proposing necessary improvements. However, there is a lack of knowledge regarding the specific characteristics and competencies that are assessed in these studies.

OBJECTIVE

The objective of this study is to characterize published studies focusing on the assessment of professional competencies among physicians in Peru.

METHODS

A comprehensive scoping review was conducted, encompassing scientific journal publications that evaluated the professional competencies of physicians in Peru. The search was performed in PubMed, Google Scholar, Scopus, and SciELO, with the review period extending until 2022. The identified competencies were classified using the Accreditation Council for Graduate Medical Education (ACGME) and the Ministry of Health of Peru (MINSA) frameworks. The findings were presented using absolute and relative frequency measures.

RESULTS

A total of forty-nine studies focused on the assessment of professional competencies among physicians were identified, indicating an upward trend over the years. The primary focus of these studies was on evaluating competencies related to medical knowledge (79.6% according to ACGME classification) and the treatment of health problems (57.1% according to MINSA classification). However, there was a noticeable lack of emphasis on assessing behavioral competencies such as ethics, professionalism, and communication. Most of the included studies (65.3%) were exclusively conducted in Lima. Among the studies that disclosed their funding sources, 61% were self-funded.

CONCLUSION

Most studies primarily concentrated on evaluating knowledge-based competencies, specifically in the areas of diagnosis and treatment. There is a scarcity of studies assessing other important competencies. Additionally, centralization and limited funding appear to be areas that require improvement in the evaluation of professional competencies among Peruvian physicians.

Epidemiology of tuberculosis among children in Beijing, China, 2012-2021

Data on epidemiology trends of paediatric tuberculosis (TB) are limited in China. So, we investigated the clinical and epidemiological profiles in diagnosed TB disease and TB infection patients at Beijing Children's Hospital. Of 3 193 patients, 51.05% had pulmonary TB (PTB) and 15.16% had extrapulmonary TB (EPTB). The most frequent forms of EPTB were TB meningitis (39.05%), pleural TB (29.75%), and disseminated TB (10.33%). PTB patients were significantly younger and associated with higher hospitalization frequency. Children aged 1-4 years exhibited higher risk of PTB and TB meningitis, and children aged 5-12 years had higher risk of EPTB. The proportion of PTB patients increased slightly from 40.9% in 2012 to 65% in 2019, and then decreased to 17.8% in 2021. The percentage of EPTB cases decreased from 18.3% in 2012 to 15.2% in 2019, but increased to 16.4% in 2021. Among EPTB cases, the largest increase was seen in TB meningitis. In conclusion, female and young children had higher risk of PTB in children. TB meningitis was the most frequent forms of EPTB among children, and young children were at high risk of TB meningitis. The distribution of different types of EPTB differed by age.

How can we improve latent tuberculosis infection management using behaviour change wheel: a systematic review

BACKGROUND

To ensure the effective delivery of latent tuberculosis infection (LTBI) care, it is vital to overcome potential challenges in LTBI management. This systematic review aims to identify the barriers and interventions to improve LTBI management using the Capability, Opportunity, and Motivation-Behaviour (COM-B) model and Behaviour Change Wheel (BCW).

METHODS

A systematic literature search was performed on five electronic databases from database inception to 3 November 2021. A two-step technique was used in the data synthesis process: (i) the barriers of LTBI management were identified using the COM-B model, followed by (ii) mapping of intervention functions from BCW to address the identified barriers.

RESULTS

Forty-seven eligible articles were included in this review. The findings highlighted the need for a multifaceted approach in tackling the barriers in LTBI management across the public, provider and system levels. The barriers were summarized into suboptimal knowledge and misperception of LTBI, as well as stigma and psychosocial burden, which could be overcome with a combination of intervention functions, targeting education, environment restructuring, persuasion, modelling, training, incentivization and enablement.

CONCLUSIONS

The remedial strategies using BCW to facilitate policy reforms in LTBI management could serve as a value-added initiative in the global tuberculosis control and prevention program.

Social Determinants of Adherence to Treatment for Tuberculosis Infection and Disease Among Children, Adolescents, and Young Adults: A Narrative Review

Global efforts to eliminate tuberculosis (TB) must address the unique barriers that children (ages 0 through 9 years) and adolescents/young adults (AYA; ages 10 through 24 years) face in adhering to treatment for TB infection and disease. We conducted a narrative review to summarize current knowledge on the social determinants of treatment adherence among these age groups to guide efforts and policy to address their unique needs. Our findings revealed that research on TB treatment adherence among children and AYA is still in its nascent stage. The current literature revealed structural/community-, health system-, household-, and individual-level factors that influence treatment adherence and varied with developmental stage. There is a need to develop multilevel interventions to address the unique challenges that children and AYA face in adhering to TB treatment.

"If I've got latent TB, I would like to get rid of it": Derivation of the CARD (Constraints, Actions, Risks, and Desires) Framework informed by South African healthcare worker perspectives on latent tuberculosis treatment

BACKGROUND

Healthcare workers (HWs) have at least twice the risk of tuberculosis (TB) compared to the general population. There is growing emphasis on latent TB infection (LTBI) in high-risk populations. Yet we know little about HWs' perspectives of LTBI testing and treatment to inform implementation in high-incidence settings. We developed a qualitative networked approach to analyze HWs' perspectives on LTBI testing and treatment.

METHODS

We conducted 22 in-depth interviews with nurse and physician stakeholders, who had been recruited as part of a larger study evaluating TB transmission risk in HWs at Tygerberg Hospital, Cape Town, South Africa. We performed open coding to identify emergent themes and selective coding to identify relevant text citations. We used thematic analysis to inductively derive the CARD (Constraints, Actions, Risks, Desires) framework.

RESULTS

All HWs desired to avoid developing TB but few felt this was actionable. Despite LTBI knowledge gaps, safety and cost concerns, most HWs reported hypothetical willingness to take LTBI treatment. The CARD framework showed that desire and action related to LTBI testing and treatment was clearly framed by the interactions between constraints, administrative action, and risk. The surprise HWs described on receiving a negative LTBI (Quantiferon-Plus) result suggests LTBI testing may recalibrate HWs' perceptions regarding the futility of actions to reduce their TB risk.

CONCLUSIONS

LTBI testing and treatment are acceptable to HWs and could counteract the perceived inevitability of occupational TB infection that currently may limit risk reduction action. This should be coupled with administrative leadership and infrastructural support. The CARD analytic framework is a helpful tool for implementation scientists to understand current practices within complex health systems. Application of CARD could facilitate the development of contextually-relevant interventions to address important public health problems such as occupational TB.

Poor adherence to TB diagnosis guidelines among under-five children with severe acute malnutrition in central India: A missed window of opportunity?

BACKGROUND

In India, under-five children with Severe Acute Malnutrition (SAM) are referred to Nutritional Rehabilitation Centers (NRCs). NRCs screen the causes of SAM including tuberculosis (TB). The national TB programme recommends upfront testing with a rapid molecular test if TB is suspected in children.

OBJECTIVE

We estimated the yield of and adherence to the TB diagnostic guidelines (clinical assessment and assessment for microbiological confirmation) among under-five children with SAM admitted at NRCs (six in district Sagar and four in district Sheopur) of Madhya Pradesh, India in 2017. We also explored the challenges in screening from the health care providers' perspective.

METHODS

It was an explanatory mixed method study. The NRC records were reviewed This was followed by three key informant interviews and three focus group discussions among staff of NRC and TB programme. Manual descriptive thematic analysis was performed.

RESULTS

Of 3230, a total of 2665(83%) children underwent Mantoux test, 2438(75%) underwent physical examination, 2277(70%) were asked about the symptoms suggestive of TB, 1220(38%) underwent chest radiograph and 485(15%) were asked for recent contact with TB. A total of 547(17%) underwent assessment for microbiological confirmation. Of 547, a total of 229 gastric aspirate specimens underwent rapid molecular test (24% positive) and 318 underwent sputum microscopy (44% positive). A total of 223 were diagnosed as TB (195 microbiologically and 28 clinically confirmed) and 209 were initiated on anti-TB treatment. The treatment outcome was favourable (cure or treatment completed) for 70(31%) and not recorded for 121(54%). The main perceived challenges in screening for TB were poor team skills, lack of diagnostic facilities and poor understanding of the guidelines due to inadequate training.

CONCLUSION

Though NRCs provided a unique window of opportunity for the screening and management of TB among under-five children with SAM, the utilization of this opportunity remained suboptimal.

Epidemiological Trends in the Form of Childhood Tuberculosis in a Referral Tuberculosis Hospital in Shandong, China

Background

In China, the prevalence of tuberculosis (TB) diseases and epidemiological trends in the TB forms among children are still unclear; a retrospective study was conducted aiming to assess it.

Methods

Between January 2007 and September 2020, 1577 consecutive childhood TB patients (aged ≤ 15 years) were included in the study. Data, including demographic information and underlying diseases, were collected from medical records. Then, patients were categorized and reported according to the anatomical site of TB disease. To analyze the epidemiological trends in the proportion of each form of TB disease, a linear-by-linear association was used, and a P value of <0.05 was considered to indicate that a significant change had occurred in the proportion of TB disease over the studied period.

Results

During the fourteen-year study period, a total of 1577 children patients were enrolled, including 954 boys (60.5%) and 623 girls (39.5%), with a mean age of 9.26 ± 5.18 years. Among the studied patients, 810 (51.4%) patients have pulmonary TB, 1137 (72.1%) have extrapulmonary TB, 372 (23.6%) have both conditions, and another 765 (48.5%) extrapulmonary cases presented in isolated form. Pleural TB (29.0%) and tuberculous lymphadenitis (23.7%) were the most frequent two forms of childhood TB. In addition, during the past decade, the proportions of pulmonary TB, pleural TB, and tuberculous lymphadenitis showed an increasing trend (all P < 0.05). However, no significant trends in the proportions of other forms of TB disease, such as extrapulmonary TB (P > 0.05), tuberculous meningitis (P > 0.05), endobronchial TB (P > 0.05), and disseminated TB (P > 0.05), were found.

Conclusion

Our findings suggest that childhood TB is facing new challenges, and the policy should be adjusted timely to fit the real situation.

In the eye of the multiple beholders: Qualitative research perspectives on studying and encouraging quality of TB care in India

This paper outlines insights qualitative research brings to the study of quality of care. It advocates understanding care as sequential, interpersonal action aimed at improving health and documenting the networks in which care occurs. It assesses the strengths and weakness of contemporary quantitative and qualitative approaches to examining quality of care for tuberculosis (TB) before outlining three qualitative research programs aimed at understanding quality of TB in India. Three case studies focus on the diagnosis level in the cascade of TB care and use qualitative research to examine the clinical use of pharmaceuticals as diagnostics, the development of diagnostic tests, and the role of care providers in the utilization of diagnostic services. They show that 1) care must be understood as part of relationships over time, 2) the presence or absence of technologies does not always imply their expected use in care, 3) physicians' provision of care is often inflected by their perceptions of patient desires, and 4) effective care is not always perfectly aligned with global health priorities. Qualitative methods with a networked perspective on care provide novel findings that can and have been used when developing quality of care improvement interventions for TB.

A Framework for Improving the Engagement of Medical Practitioners in an E-Training Platform for Tuberculosis Care and Prevention

We propose a new framework to improve the engagement of medical practitioners in a planned e-training platform for the successful identification and effective management of presumptive cases of tuberculosis (TB) in Pakistan. Our work is aligned with the World Health Organization’s TB-DOTS (Directly Observed Treatment Short-course) strategy for promoting the effective management of tuberculosis. We start by presenting previous work done at Mercy Corps Pakistan for training medical practitioners, then present the results of a recent survey we administered to a random sample of medical practitioners in Pakistan to learn about their requirements and readiness to embrace a new e-training platform and methodology. Informed by feedback from the survey, we formulated a detailed requirement analysis of the five key learning areas (or phases) that we believe are fundamental to the success of a TB e-training platform. Moreover, survey results revealed that an on-spot, on-demand, and competency-based learning tool can potentially improve the engagement of medical practitioners in the process. Building on the insights gained from the survey, we finally describe our initial UX (user experience) prototypes for phase 1, which corresponds to the identification of presumptive tuberculosis cases.

Baseline Predictors of Treatment Outcomes in Children With Multidrug-Resistant Tuberculosis: A Retrospective Cohort Study

BACKGROUND

Globally, >30 000 children fall sick with multidrug-resistant (MDR) tuberculosis every year. Without robust pediatric data, clinical management follows international guidelines that are based on studies in adults and expert opinion. We aimed to identify baseline predictors of death, treatment failure, and loss to follow-up among children with MDR tuberculosis disease treated with regimens tailored to their drug susceptibility test (DST) result or to the DST result of a source case.

METHODS

This retrospective cohort study included all children ≤15 years old with confirmed and probable MDR tuberculosis disease who began tailored regimens in Lima, Peru, between 2005 and 2009. Using logistic regression, we examined associations between baseline patient and treatment characteristics and (1) death or treatment failure and (2) loss to follow-up.

RESULTS

Two hundred eleven of 232 (90.9%) children had known treatment outcomes, of whom 163 (77.2%) achieved cure or probable cure, 29 (13.7%) were lost to follow-up, 10 (4.7%) experienced treatment failure, and 9 (4.3%) died. Independent baseline predictors of death or treatment failure were the presence of severe disease (adjusted odds ratio [aOR], 4.96; 95% confidence interval [CI], 1.61-15.26) and z score ≤-1 (aOR, 3.39; 95% CI, 1.20-9.54). We did not identify any independent predictors of loss to follow-up.

CONCLUSIONS

High cure rates can be achieved in children with MDR tuberculosis using tailored regimens containing second-line drugs. However, children faced significantly higher risk of death or treatment failure if they had severe disease or were underweight. These findings highlight the need for early interventions that can improve treatment outcomes for children with MDR tuberculosis.

New Diagnostics for Childhood Tuberculosis

The challenge of diagnosing childhood tuberculosis (TB) results from its paucibacillary nature and the difficulties of sputum collection in children. Mycobacterial culture, the diagnostic gold standard, provides microbiological confirmation in only 30% to 40% of childhood pulmonary TB cases and takes up to 6 weeks to result. Conventional drug susceptibility testing requires an additional 2 to 4 weeks after culture confirmation. In response to the low sensitivity and long wait time of the traditional diagnostic approach, many new assays have been developed. These new tools have shortened time to result; however, none of them offer greater sensitivity than culture.
