Implementing and evaluating the efficacy of an acute care urology model of care in a large community hospital.

INTRODUCTION: We implemented an acute care urology (ACU) model at a large Canadian community hospital to determine the impacts on safe and timely care of patients with renal colic. The model includes a dedicated ACU surgeon, a clinic for emergency department (ED) referrals, and additional daytime operating room (OR) blocks for urgent cases. METHODS: We conducted a chart review of 579 patients presenting to the ED with renal colic. Data was collected before (pre-intervention, September to November 2015) and after (post-intervention, September to November 2016) implementation of the ACU model. Secondary methods of evaluation included surveying patients and 20 ED physicians to capture subjective feedback. RESULTS: Of the 579 patients presenting with renal colic,194 were diagnosed with an obstructing kidney stone and were referred to urology for outpatient care. The ED-to-clinic time was significantly lower for those in the ACU model (p<0.001). Furthermore, the ACU clinic resulted in significantly more patients being referred for outpatient care (p=0.0004). There was also higher likelihood that patients would successfully obtain an appointment post-referral (p=0.0242). The number of after-hours and weekend surgeries decreased significantly after dedicated ACU daytime OR blocks were added in September 2015 (p<0.0001). All surveyed patients rated the care as either "excellent" or "very good," and all physicians believed the ACU model has improved patient care. CONCLUSIONS: The ACU model has shown benefit in ensuring timely followup for ED patients, reducing use of after-hour OR time, and improving patient and physician satisfaction.

THE USE OF CITALOPRAM HYDROBROMIDE TO MANAGE AGGRESSION IN A MALE CHIMPANZEE (PAN TROGLODYTES).

At times severe, and occasionally fatal, aggression plays an intrinsic role in chimpanzee behavior and social dynamics, particularly among male chimpanzees in both managed and free-ranging troops. At the Los Angeles Zoo, one adult male's natural aggressive behavior developed into unmanageable violence during a period of social and emotional instability consequent to the lack of an established alpha male in the colony. The severity and duration of resulting attacks on a subdominant member of the community, despite environmental and behavioral modification, indicated the need for psychopharmaceutical intervention. Prior treatment of this animal with haloperidol and gabapentin had produced undesirable side effects. Administration of citalopram hydrobromide, a selective serotonin reuptake inhibitor, successfully reduced both the intensity and duration of this male chimpanzee's attacks upon a conspecific animal with minimal observable side effects or adverse behavioral changes.
