Tb Case Studies
CHAPTER TWO
2.0 LITERATURE REVIEW
2.1 Introduction
This section of the report will be used to discuss the findings of previous studies in the area of TB case detection especially among healthcare providers. For purposes of convenience, the section will be discussed under sub-thematic areas as Knowledge regarding TB case detection, Health worker practices regarding TB case detection, challenges to TB case detection, and factors influencing low TB case detection.
2.2 Healthcare providers Knowledge regarding TB case detection
Health worker knowledge has been identified to have a direct link with delays to TB case detection. Knowledge includes the ability to recognize symptoms, identify causes and transmission routes, and familiarity with the

In the study conducted among health care workers in Iraq on Knowledge, attitude and practices regarding TB, it was found that even though health staff had relatively higher knowledge with respect to what to do at any given time, it did not translate into their practice of TB control especially in the area of investigation of a TB suspect, a situation that fostered healthy grounds for poor case finding and inappropriate case-holding practices (Hashim et al., 2005).
Again, the study on knowledge attitude and practices of healthcare workers regarding TB control among thirty government hospitals in Thailand also arrived at the conclusion that high healthcare providers' knowledge does not necessarily translate into good practice. Knowledge level was found to be in correlation with the number of TB trainings attended as well as the profession of the respondent (Lertkanokkun and Okanurak, 2013).

2.4.0 Health worker challenges contributing to low TB case detection
2.4.1 Logistics and supply chain system.
Screening and diagnosis of TB cases in the various health facilities is to a large extent dependent on the availability of adequate logistic. Lack of screening tools has been cited as a major challenge contributing to missed opportunities with regards to TB care (Dimitrova, 2006; Ngadaya et al., 2009; Artawan Eka Putra et al., 2013).
Ngadaya et al ( 2009), further reported that there were occasions when guidelines for TB case detection were not existent and even places where they existed, staff did not know about them and hence contributed to low TB case detection.

APHA Code Of Ethics And The Pandemic Ethics Dashboard (2022)
702 Words | 3 PagesSome of the resources that can assist employees like Mimi Hall and Gail Newel in executing public health measures in the face of opposition include the APHA Code of Ethics and the Pandemics Ethics Dashboard (Murtagh & Erwin, 2022). The APHA Code of Ethics provides a framework that acts as a guideline for public health professionals in making sound and ethical decisions (Murtagh & Erwin, 2022). It also offers principles and standards that champion the protection and alleviation of public health, and it can be utilized to communicate the essence and the rationale behind specific measures to the public. When professionals reference the APHA Code of Ethics, they showcase commitment to the ethical practice of public health and justify their actions.
External Dissemination Plan
594 Words | 3 PagesDissemination Plan Internal. To best disseminate Braden screening internally, it is important to include all acute care staff nurses, charge nurses, nurse administrators, case managers, unlicensed assistive personnel and involved hospital administrators. It is also important to include the acute care physicians, so that they are aware of the problem and intervention on a collaborative basis. A series of lunch and learn sessions, where staff members from each acute care shift can be exposed to the problem (including the prevalence of HAPUs in the acute care setting), the Braden Scale Screening solution, as well as an overview of benefits, costs and savings. This would be an opportunity to gain rapport with staff, and gain traction with early-adopters who will be key to ensuring a culture of taking the intervention seriously, as well as following the protocols and reporting procedures.
The Joint Commission Survey
1017 Words | 5 PagesThe Joint Commission is involved in making sure the health care facilities are providing the patient and family members of patients the effective and safe care that the patient needs and deserves. There is a close relationship between the National Patient Safety Goals (NPSG) and the results of the Joint Commission survey. If the facility were following the NPSG’s then the facility would have more of likelihood that the organization will receive a good survey results from the Joint Commission. There are serious consequences for the health care organization if the organization does not meet the benchmarks set by the Joint Commission. Multiple tools out there will aid this author in determining if the organization that this author works in is

The government should also prioritize the restructuring, reorganizing and decentralization of the health facility systems which had been neglected for years (Hwang, 2007). Infectious diseases are direct; they can rapidly affect an entire region if not managed properly. With globalization the need to manage these diseases is more important than ever as these

Health Crisis In Texas
464 Words | 2 PagesFacing a health crisis that deals with many of the populace involves: “respect for society, coordination of organizations and an institution with scientific weight to the people and to the media, who acted as spokesman in situations of public health risk, to get confidence citizens” (Busko). The technical capacity of health professionals “is more proven than the public officials, which suggests a greater share of the former and better training of the second” (Selby). The state of Texas has never had a crisis like this or others experiences that were similar. Crises are challenges that must be learned from both their errors and successes since they serve to bring about to the devices and improve the response to other crises. It is important to perform analysis of previous responses, and research and testing, to prepare themselves for another health crisis.

Kalb Do No Harm Analysis
378 Words | 2 PagesIn the articles “ Do No Harm,” and “ How a Team of Doctors… Created a Culture of Safety”, Kalb presents a strong point on improving hospitals’ safety to reduce preventable medical errors including infections. The author seems like she’s very into this topic about healthcare and how medical system works. In “ Do No Harm,” Kalb tends to give the readers the general ideas on physicians’ malpractice issue, focusing on the details rather than on a specific solution. However, in “ How a team doctors,” she provides readers the introduction of the issue as well as presents some specific solutions to the problem. Both of the articles are very well researched and reliable since Kalb supports her work with a lot of statistics, including the numbers of

Quarantine Next Door Case Study
899 Words | 4 PagesIt is imperative that all people subjected to quarantine or isolation should be notified of pro and con associated with the interference. Interchangeably, it allows the public to have chances to fully understand those responses and to take active parts in quarantine. The medical experts should also advocate for transparency and inform the public of health issues. It is a win-win! On top of that, collaborations between medical professionals are significant in that their cooperation ensures those medical measures to achieve comparable goals; the effectuality of an intervention is guaranteed and the wellbeing of the society is warranted.
Multidrug Resistant Tuberculosis Research Paper
661 Words | 3 PagesMDR TB is difficult to screen for because the symptoms are the same as normal active TB except the now when they are being treated they are just not responding to the medicine, and that process of diagnostics takes too long to be efficient. A study was conducted on the rapid tested used of the diagnosis of DR TB they discovered that “... the World Health Institute (WHO) estimated that half of all drug-resistant tuberculosis (DR TB) cases were detected globally. Undetected resistance results in treatment failure and increase the risk of TB transmission, and patient mortality”(Cantanzo 2). This statistic alone demonstrates the shocking reality and dangers of how little the medical field knows about this strain of TB. Increasing funding could send up to a fifty percent increase of patients with MDR TB going home with answers and a treatment plan.
