Acute Pyelonephritis II: Diagnostic Studies and Management01:28

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
Bacterial Meningitis I: Introduction01:22

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
Endocarditis IV: Nursing Management01:29

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Summary

Indigenous patients with deep neck space infections (DNSIs) experienced significantly longer hospital stays and higher readmission rates. This highlights the need to consider Indigenous status in DNSI risk assessment and care models.

Area of Science:

  • Medical research
  • Infectious diseases
  • Surgical outcomes

Background:

  • Deep neck space infections (DNSIs) pose significant clinical challenges.
  • Existing research identifies risk factors for adverse DNSI outcomes, but Indigenous status has not been directly linked.
  • This study investigates the impact of Indigenous status on DNSI patient outcomes.

Purpose of the Study:

  • To analyze the association between Indigenous status and outcomes in patients with deep neck space infections (DNSIs).
  • To identify demographic and clinical factors influencing hospital length of stay (LOS) and readmission rates in DNSI patients.
  • To inform risk stratification and management strategies for DNSIs, particularly for Indigenous populations.

Main Methods:

  • Retrospective cohort analysis of 351 adult patients with DNSIs admitted to a South Australian quaternary ICU (2018-2024).
  • Outcomes assessed included hospital length of stay (LOS), 30-day readmission rates, and returns to surgery.
  • Multivariable linear regressions analyzed associations, considering Indigenous status and socioeconomic status (SEIFA deciles).

Main Results:

  • Aboriginal and Torres Strait Islander patients had significantly longer hospital stays (adjusted mean ratio 1.41) and over five times higher readmission rates (OR 5.59) compared to non-Indigenous patients.
  • Increased age (per 10 years) was associated with longer LOS (6% rise).
  • Elevated glucose levels correlated with increased LOS (3% rise per unit).

Conclusions:

  • Indigenous status is a critical factor influencing DNSI outcomes, necessitating its inclusion in risk stratification.
  • Limited literature exists on Indigenous status and surgical outcomes in DNSIs, indicating a need for further research.
  • Development of co-designed care models with Indigenous patients and healthcare professionals is crucial to address healthcare disparities.
