OBJECTIVE To compare the outcome of canine pyometra surgeries performed at referral hospitals with those performed at community clinics (outpatient settings), and to evaluate factors that impact outcome. ANIMALS 133 client-owned dogs with pyometra treated with ovariohysterectomy (OHE) at 2 community clinics or 2 referral hospitals between July 1, 2017, and June 30, 2019. PROCEDURES A retrospective electronic medical record search was used to identify eligible cases. Data about patient demographics and clinical characteristics were collected and analyzed for factors that could have impacted outcome. RESULTS Eighty-three dogs were treated at referral hospitals; 50 dogs were treated at community clinics. Survival to hospital discharge for all dogs was 97% (129/133) and did not differ between treatment facility type. Dogs treated at both types of facilities were similar in age, body weight, and clinical signs. Median duration between diagnosis and OHE was significantly shorter for dogs treated at referral hospitals (0 day; range, 0 to 0.7 days) versus community clinics (1.0 day; range, 0 to 14.0 days); however, delay was not related to survival to hospital discharge. Duration of hospitalization did not impact survival to hospital discharge nor survival for at least 1 week after surgery. CLINICAL RELEVANCE Results indicated that OHE for pyometra in dogs has a good outcome and that, although prompt surgical treatment remains a goal, in cases where limitations to performing surgery exist, a delay until surgery or discharging patients the same day is still associated with a high degree of success. |
