Common Internal Medicine Cases in General Medical Wards

Most Prevalent Conditions

The most common internal medicine cases requiring ward admission globally are community-acquired pneumonia, urinary tract infections, skin and soft tissue infections, acute exacerbations of chronic obstructive pulmonary disease (COPD), and chest pain syndromes, according to the Infectious Diseases Society of America 1, 2

COPD exacerbations are among the priority infections identified for antibiotic stewardship, given their high incidence and contribution to overall antibiotic use, as recommended by the European Respiratory Society 1
Bronchitis and lower respiratory tract infections frequently require inpatient management, particularly when complicated by underlying comorbidities, according to the European Respiratory Society 3, 1

Both lower and upper urinary tract infections are extremely common ward admissions, particularly in elderly patients and those with comorbidities, as noted by the Infectious Diseases Society of America 1, 4
Asymptomatic bacteriuria is frequently encountered but should not be treated in most populations, as inappropriate treatment contributes substantially to antimicrobial resistance, according to the Infectious Diseases Society of America 4

Chest pain comprises 5-20% of emergency department visits, with approximately 10-15% ultimately diagnosed with acute myocardial infarction requiring ward or coronary care unit admission, as reported by the European Society of Cardiology 5
Patients with ongoing chest pain, ischemic ECG changes, positive troponin tests, or hemodynamic abnormalities require specialized coronary care or intensive care unit admission, according to the European Society of Cardiology 5

Skin and soft tissue infections, including cellulitis, erysipelas, and complicated surgical site infections, frequently require hospitalization for intravenous antibiotics and surgical intervention, as recommended by the Infectious Diseases Society of America 1, 6
Sepsis remains a leading cause of admission, with severe cases requiring intensive monitoring and aggressive antimicrobial therapy, according to the Infectious Diseases Society of America 1, 2

Complicated intra-abdominal infections require hospitalization for surgical intervention and broad-spectrum antimicrobial therapy, with morbidity rates of 59% and mortality rates of 21% in emergency surgical cases, as reported by the Surgical Infection Society 6

Elderly patients (≥65 years) in long-term care facilities have particularly high rates of pneumonia, urinary tract infections, and skin infections, as noted by the Infectious Diseases Society of America 2
Fever may be absent or low-grade in LTCF residents with serious infections, making diagnosis challenging, according to the Infectious Diseases Society of America 2

Community-acquired pneumonia in children, particularly those with severe acute malnutrition, represents a distinct category requiring specialized management, as recommended by the Pediatric Infectious Diseases Society 1

Avoid screening for asymptomatic bacteriuria in most populations, as this promotes inappropriate antimicrobial use and resistance development, according to the Infectious Diseases Society of America 4
Do not delay antibiotics in severe pneumonia or sepsis—immediate administration after diagnosis is critical for mortality reduction, as recommended by the Infectious Diseases Society of America 4
