Insights

Home-based primary care clinicians diagnosed 60 infections between 2023-2024, with 35% via telehealth. Most antibiotic prescriptions were for 7 days or longer, indicating a need for further home care infection research.

Area of Science:

  • Primary Care Medicine
  • Infectious Diseases
  • Telehealth

Background:

  • Home-based primary care is increasingly important for managing patient health.
  • Understanding the types and management of infections diagnosed in home care settings is crucial.

Purpose of the Study:

  • To analyze the incidence and characteristics of infections diagnosed by home-based primary care clinicians.
  • To assess the proportion of telehealth diagnoses and antibiotic prescription patterns.

Main Methods:

  • Retrospective analysis of 60 infection diagnoses from a single home-based primary care site (2023-2024).
  • Categorization of infections (urinary tract, skin/soft tissue, pneumonia, influenza-like illness).
  • Evaluation of telehealth utilization and antibiotic prescription durations.

Main Results:

  • A total of 60 infections were diagnosed, with urinary tract infections being most common (n=31).
  • 35% of diagnoses were made via telehealth.
  • 43% of cases met standardized surveillance definitions.
  • The majority of antibiotic prescriptions (27/48) were for durations of 7 days or longer.

Conclusions:

  • Home-based primary care encounters a variety of infections, with a significant portion diagnosed remotely.
  • Current antibiotic prescribing practices in home care often involve longer durations.
  • Further research into home care infections is warranted to optimize diagnosis and treatment.

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...

Urine Studies II: Urine Culture and Sensitivity Test

A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

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...

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Urinary Tract Infection IV: Nursing Management

In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs...
