Introduction To Health Care Delivery System01:18

Introduction To Health Care Delivery System

2.8K
The healthcare system is constantly changing and complex. Various services are available from different healthcare providers, but gaining access to these services has become challenging for people with limited healthcare insurance. Uninsured people present a challenge to healthcare because they frequently postpone or forego treatment.
The Institute of Medicine (IOM) advocates for a patient-centered, effective, safe, timely, equitable, and effective healthcare system. The National Priorities...

Specialized Care Centers and Settings-II

736
Rural Health Centers
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...

Secondary Healthcare System01:11

Secondary Healthcare System

1.5K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...

Preventive Healthcare Services

1.0K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Nursing Ethical Principles II01:27

Nursing Ethical Principles II

993
Ethical principles are essential in guiding nurses to fulfill their responsibilities, focusing on the quality of nursing care and decision-making. These principles, including autonomy, beneficence, non-maleficence, justice, and fidelity, shape the ethical framework within healthcare settings.
Consider the following scenario, which illustrates how these principles are applied in the care of Mr. John, a fifty-year-old teacher diagnosed with metastatic liver cancer.
Initially, Mr. John's...

Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

314
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Area of Science:

  • Public Health
  • Health Disparities Research
  • Oncology

Background:

  • Breast cancer screening (BCS) disparities disproportionately affect underserved populations, leading to poorer health outcomes.
  • Identifying specific patient and health system factors contributing to these disparities is crucial for targeted interventions.

Purpose of the Study:

  • To explore granular associations between breast cancer screening (BCS) and patient sociodemographic factors.
  • To investigate how patient characteristics and provider attributes influence BCS rates within an urban safety-net health system.

Main Methods:

  • Retrospective review of 11,962 female patients aged 50-74 in an urban safety-net health system (2019 data).
  • Analysis included patient sociodemographic data, health characteristics, and provider gender/specialty.
  • Bivariate analyses and multivariable logistic regression were employed.

Main Results:

  • The overall BCS rate was 69.7%.
  • Patients with White race, English proficiency, and Medicare insurance showed lower BCS rates.
  • Limited English proficiency, serious mental illness, and substance use disorder were associated with lower screening odds.
  • Most non-White racial groups and non-English language speakers had higher odds of screening compared to White, English-speaking counterparts.
  • Female providers and internal medicine-trained providers were linked to higher screening rates.

Conclusions:

  • Numerous patient and health system factors contribute to breast cancer screening disparities.
  • Understanding these complex interactions is vital for informing policy and improving BCS access for vulnerable populations.
