Rapid implementation of virtual clinics due to COVID-19: report and early evaluation of a quality improvement initiative.

BACKGROUND: The COVID-19 outbreak has placed the National Health Service under significant strain. Social distancing measures were introduced in the UK in March 2020 and virtual consultations (via telephone or video call) were identified as a potential alternative to face-to-face consultations at this time. LOCAL PROBLEM: The Royal National Orthopaedic Hospital (RNOH) sees on average 11 200 face-to-face consultations a month. On average 7% of these are delivered virtually via telephone. In response to the COVID-19 crisis, the RNOH set a target of reducing face-to-face consultations to 20% of all outpatient attendances. This report outlines a quality improvement initiative to rapidly implement virtual consultations at the RNOH. METHODS: The COVID-19 Action Team, a multidisciplinary group of healthcare professionals, was assembled to support the implementation of virtual clinics. The Institute for Healthcare Improvement approach to quality improvement was followed using the Plan-Do-Study-Act (PDSA) cycle. A process of enablement, process redesign, delivery support and evaluation were carried out, underpinned by Improvement principles. RESULTS: Following the target of 80% virtual consultations being set, 87% of consultations were delivered virtually during the first 6 weeks. Satisfaction scores were high for virtual consultations (90/100 for patients and 78/100 for clinicians); however, outside of the COVID-19 pandemic, video consultations would be preferred less than 50% of the time. Information to support the future redesign of outpatient services was collected. CONCLUSIONS: This report demonstrates that virtual consultations can be rapidly implemented in response to COVID-19 and that they are largely acceptable. Further initiatives are required to support clinically appropriate and acceptable virtual consultations beyond COVID-19. REGISTRATION: This project was submitted to the RNOH's Project Evaluation Panel and was classified as a service evaluation on 12 March 2020 (ref: SE20.09).

Determination of reference intervals for umbilical cord arterial and venous blood gas analysis of healthy Thoroughbred foals.

Although umbilical cord blood gas analysis is considered the best way to assess in utero oxygenation in human neonates, there is limited evaluation of this method in equine neonatology. Our objectives were to assess the practicality of obtaining umbilical cord blood gas samples in the field and to determine umbilical cord arterial and venous blood gas reference intervals (RI) for healthy, newborn foals. Thoroughbred foals >320 days gestation from healthy mares with uneventful pregnancies at one stud farm were evaluated. All parturitions were observed, with paired umbilical arterial and venous whole-blood samples obtained immediately following parturition for blood gas and lactate concentrations measured in duplicate. Apgar scores were assigned immediately and 10 min after birth, with all foals subsequently examined on days 1-28 to monitor for development of perinatal asphyxia syndrome. Foals were excluded from analysis based on abnormalities of stage 2 labour, Apgar scores and gross and histological placental assessment. Data was analysed using a Student's t-test, Pearson's correlation and the Robust method with P ≤ 0.05 significant. Umbilical cord samples were simple to obtain with minimal disruption to the foaling environment. Of the n = 34 foals assessed, n = 7 were excluded based on premature placental separation deliveries. The mean time for stage 2 labour and blood gas analysis after parturition was 17.3 ±â€¯5.1 min and 5.0 ±â€¯2.3 min, respectively. RI were identified for umbilical arterial and venous pH (7.19-7.42 vs. 7.34-7.44), PO2 (15.5-48.39 mmHg vs. 16.6-52.7 mmHg), PCO2 (49.5-82.29 mmHg vs. 45.4-63.1 mmHg), SO2 (9.19-76.89% vs. 39.9-84.88%), bicarbonate (27.3-38.7 mmol/l vs. 27.7-37.8 mmol/l), base excess (0.36-12.9 mmol/l vs. 1.97-13.1 mmol/l), TCO2 (28.99-40.3 mmHg vs. 29.0-39.5 mmHg) and lactate (1.4-7.3 mmol/l vs. 1.3-4.9 mmol/l). Umbilical arterial samples had lower pH (P < 0.0001), PO2 (P = 0.002) and SO2 (P < 0.0001) and higher PCO2 (P < 0.0001) and lactate (P < 0.0001) than venous samples. The initial Apgar score was positively correlated to umbilical arterial SO2 (r = 0.4, P = 0.05) and negatively with umbilical arterial TCO2 (r = -0.6, P = 0.004). Overall, umbilical cord sampling was simple and minimally disruptive, with RI obtained for blood gas measurements. RI for umbilical blood gas measurements from a larger population of healthy and unhealthy foals is required to evaluate the accuracy of this method for assessing in utero oxygenation.

Perinatal asphyxia syndrome in the foal: review and a case report.

: This report presented a brief overview of the literature on the perinatal asphyxia syndrome (PAS) in foals as a prelude to a description of the investigation and treatment of acute onset seizures in a 24-hour-old Thoroughbred colt foal.PAS can cause a wide variety of clinical abnormalities, of which seizures due to encephalopathy are the most significant. The structural and biochemical components of CNS neurones are disrupted by the shift from oxidative to anaerobic metabolism, with a resultant deficit in cellular energy. The cells succumb to the combined effects of acidosis, neurotoxic activities of glutamate, nitric oxide and free radicals, lipid peroxidation, accumulation of intracellular calcium and destructive overactivity of intracellular enzymes. Concurrently, the hypoxia affects other organ systems and management of foals presenting with CNS signs requires the veterinarian to undertake a thorough clinical examination and to institute appropriate therapy for the various derangements induced by the hypoxic-ischaemic episode. Diazepam (0.1 to 0.2 mg/kg bwt) can be used for short-term control of seizures; phenobarbital (2 to 10 mg/kg bwt) may be required for more prolonged treatment of recurrent seizures. The needs of the affected foal for nutrients, fluids and electrolytes, antimicrobial therapy and ancillary therapies were discussed in the literature review and illustrated in the case report.

Right dorsal colitis in the horse: minireview and reports on three cases in Ireland.

: Right dorsal colitis (RDC) is an ulcerative inflammatory bowel disorder of the horse that has been associated with the administration of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in horses treated when dehydrated or toxaemic. The acute form of RDC may result in profuse diarrhoea, severe colic, dehydration, endotoxic shock and even death; the chronic form may be manifest by mild to moderate intermittent colic, ventral oedema and weight loss with or without diarrhoea. The most consistent laboratory findings are anaemia, hypoproteinaemia, hypoalbuminaemia and hypocalcaemia. Medical management of RDC requires avoidance of NSAIDs, of stressful experiences and of large-volume diets. Specific medications such as sucralfate and metronidazole have been used to treat RDC in the horse. The use of dietary additions such as psyllium and corn oil has been mentioned in the literature.RDC has not been reported previously in Ireland or Britain; here we report that the condition was diagnosed in three horses in Ireland on the bases of a history of phenylbutazone therapy, clinical signs, clinical pathology and ultrasonography. In two of the three horses the diagnosis was confirmed by direct inspection of the affected colon at celiotomy.
