Objective: To estimate the incidence of adult patients diagnosed with acute cystitis and evaluate the assessment and treatment of acute cystitis in Nuuk, Greenland. Study design: Retrospective follow-up study including all adult patients diagnosed with acute cystitis at Queen Ingrid Primary Health Care Center within a fourteen-day long observation period. Methods: Patients diagnosed with acute cystitis were identified using the electronical medical record (EMR). From EMR information about age, gender, diagnose, examinations, treatment and medical history was obtained. Results: A total of 66 patients (7 males and 59 females) diagnosed with acute cystitis were identified. Out of the 66 patients, 34 patients were classified with uncomplicated acute cystitis, while the other 32 patients were classified with complicated acute cystitis. The overall incidence rate among female patients was 189/1,000 person-years (95 % CI 181-198) and 20/1,000 person-years (95% CI 17-23) among male patients. A urine dipstick was performed in 53.0 % of the cases while a urine culture was performed in 39.4 % of the cases. Escherichia coli was the most common uropathogen found in the urine cultures (42.3% of the cases). In 34.6 % of the cases, no bacteria were found in the urine cultures. The majority of patients (98.5%) were treated with antibiotics, almost exclusively Sulfamethizole or Pivmecillinam (92.3 % of patients treated with antibiotics). Conclusion: Acute cystitis is a common diagnosis among adult women in Nuuk, Greenland, with E. coli as the most common uropathogen. The majority of patients are treated with the recommended antibiotics.
