Current Trends in Nursing II

3.3K
Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Issues And Trends In Healthcare Delivery System

6.1K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Inflammatory Bowel Disease V: Surgical Management

395
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

401
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Introduction To Health Care Delivery System

3.6K
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...

Area of Science:

  • Critical care medicine
  • Anesthesiology
  • Surgical Intensive Care Unit (SICU)

Background:

  • The evolution of Intensive Care Units (ICUs) from Bjorn Ibsen's pioneering work in 1952 to modern SICUs highlights advancements in positive pressure ventilation and dedicated patient care.
  • The role of the intensivist has expanded to manage patient flow, optimize resource allocation, and arbitrate between surgical demands and patient interests, ensuring safety and efficacy.
  • Demographic shifts towards an older, sicker population necessitate a re-evaluation of critical care resource allocation and treatment strategies.

Discussion:

  • The increasing demand for advanced treatments, including organ support technologies like ECMO and CVVH, has made "technical care" a core expectation of critical care.
  • Standardized medical treatments, such as lung-protective ventilation and daily sedation vacations, have improved patient outcomes by reducing ventilator time and delirium.
  • The presence of a 24/7 on-site intensivist and a multidisciplinary critical care team (intensivist, nurse, pharmacist, respiratory therapist, physiotherapist) is associated with decreased mortality and improved patient outcomes.

Key Insights:

  • Patients with severe sepsis have significantly lower mortality rates when admitted to an ICU compared to those not admitted.
  • Rapid Response Teams (RRTs) or Medical Emergency Teams (METs) have shown success in reducing cardiac arrests and in-hospital mortality outside the ICU.
  • The effectiveness of RRTs depends not only on availability but also on the alertness and timely recognition of deteriorating patients by ward staff.

Outlook:

  • Future critical care models may involve extending ICU-level care to wards through RRTs, enhanced ward staff training, or remote patient monitoring systems.
  • The intensivist's role will become increasingly crucial in managing rising ICU demand amidst economic pressures, requiring strong leadership, communication, and collaborative skills.
  • Balancing advanced treatment options, patient expectations, and resource utilization remains a key challenge for the future of intensive care medicine.
