Case ReportsAcute Uncomplicated UTIs in Adults: Rapid Evidence Review.
An acute uncomplicated urinary tract infection (UTI) is a bacterial infection of the lower urinary tract with no sign of systemic illness or pyelonephritis in a noncatheterized, nonpregnant adult with no urologic abnormalities or immunocompromise. In women, a self-diagnosis of a UTI with the presence of typical symptoms (e.g., frequency, urgency, dysuria/burning sensation, nocturia, suprapubic pain), without vaginal discharge, is accurate enough to diagnose an uncomplicated UTI without further testing. Urine culture and susceptibility testing should be reserved for women with recurrent infection, treatment failure, history of resistant isolates, or atypical presentation to make a definitive diagnosis and guide antibiotic selection. ⋯ Clinicians should also consider the possibility of urethritis and prostatitis in men with UTI symptoms. First-line antibiotics for men with uncomplicated UTI include trimethoprim, trimethoprim/sulfamethoxazole, and nitrofurantoin for seven days. Uncomplicated UTIs in nonfrail women and men 65 years and older with no relevant comorbidities also necessitate a urine culture with susceptibility testing to adjust the antibiotic choice after initial empiric treatment; first-line antibiotics and treatment durations do not differ from those recommended for younger adults.

The management of chronic illnesses should continue during hospitalization. Some chronic conditions require immediate intervention, whereas intensification of therapy for other conditions may be delayed until after discharge. Factors such as pain, anxiety, poor sleep hygiene, and concurrent illness can result in a transient elevation of blood pressure. ⋯ The risk of venous thromboembolic disease is significantly increased for hospitalized patients. Venous thromboprophylaxis is recommended for all but low-risk patients. Pharmacologic prophylaxis with subcutaneous low-molecular-weight heparin is preferred; mechanical prophylaxis is an alternative for patients who are at high risk of bleeding or have contraindications to anticoagulation.
