Pyometra Management Practices in the High Quality, High Volume Spay-Neuter Environment

Abstract

Pyometra management in the high quality, high volume spay-neuter (HQHVSN) environment is not well documented. The goal of this study was to identify pyometra management practices and patient outcomes in the HQHVSN environment. An electronic survey was piloted and distributed to HQHVSN clinics using Survey Monkey via email lists and social media. A total of 118 responses were received from June to July 2020. Respondents were distributed across the United States with the majority of clinics associated with a shelter (75%). Clinics performed a median of 25 spays and neuters per day and 5000 per year. Most clinics (86%) were willing to treat nonincidental pyometras at least sometimes, and nearly all of these clinics (97%) were willing to accept pyometra referrals. Of these clinics, nearly all (95%) felt they had the necessary resources to treat most pyometras that presented and that a pyometra case was only modestly disruptive to their surgery flow. Most clinics (70%) charged a fee for treatment, charging a median of $200 for dogs and $125 for cats. This is much lower as compared to the estimated ranges for private practice ($600-$2500) and emergency hospitals ($1500-$3579). The majority of patients that HQHVSN clinics accepted for treatment were seen the same day (50%) or next day (42%). These clinics estimated that of the animals who presented, 76% were BAR or QAR, 20% were depressed or nonambulatory, and 4% were obtunded and lateral. Estimated survival for these treated groups were 98%, 80%, and 38%, respectively. HQHVSN clinics may represent a resource for treating pyometras when treatment is disruptive to the schedule of a private practice or clients present with financial limitations. There is an opportunity for HQHVSN and private practice to form a partnership to leverage the strengths of both models and improve access to care for pets.
