Involvement of veterinary students in the placement of intravenous catheters in adult horses in a teaching hospital does not significantly increase the rate of catheter complications.

OBJECTIVE: To determine whether student involvement in intravenous catheter (IVC) placement increases the risk for complications and to report the rate and types of complications associated with IVCs in adult horses in a university teaching hospital. ANIMALS: 455 IVCs placed in 394 horses. METHODS: Data relevant to IVC placement and removal were retrieved from an electronic medical record search including records of adult horses from January 1 to December 31, 2022. Data retrieved from records included the role of the individual who prepared the site and placed the IVC, site of IVC placement, and type of IVC. The reason for removal of the IVC and presence or absence of detectable changes within the vein at the time of removal were documented in addition to clinical data, allowing for classification of each case. Data were reviewed retrospectively, and statistical analyses were performed using mixed-effects logistic regression models. Significance was set at P ≤ .05. RESULTS: The overall rate of complications was 15.6%, and the most common type of complication was swelling of the vein. Students were involved in 87 of 455 IVC site preparations and placements, and there were no statistically significant differences in complication rates between IVC sites prepared or placed by veterinary students versus nonstudent personnel. CLINICAL RELEVANCE: Veterinary personnel and clients may be hesitant to allow student involvement in IVC placement in horses, but these data suggest that student involvement does not increase the risk of IVC complications.

Error reporting in a large animal veterinary teaching hospital identifies medication errors occur most often in the prescribing phase of therapy.

OBJECTIVE: To identify the rate at which medication errors occurred over a 2-year period in a large animal veterinary teaching hospital and describe the types of errors that occurred. SAMPLE: 226 medication errors over 6,155 large animal visits occurred during the study period. Multiple errors may have affected the same patient. METHODS: Medication error reports from March 1, 2021, to March 31, 2023, were reviewed retrospectively and classified by species, type of drug, and month and day of the week the error occurred. Errors were categorized according to multiple previously developed systems to allow for comparison to other studies. RESULTS: 226 medication errors occurred over 6,155 patient visits in a 2-year period: 57.5% (130/226) were identified by a dedicated large animal pharmacist, and 64.2% (145/226) of errors were identified and corrected before reaching the patient. Prescription/medication order errors (58.4% [132/226]) occurred significantly more often than errors in medication preparation (21.7% [49/226]; P < .001) and administration (19.6%; P < .001). Antibiotics (48.7% [110/226]) and NSAIDs (17.7% [40/226]) were the drug classes most involved in errors. CLINICAL RELEVANCE: Most medication errors in this study occurred in the ordering/prescribing phase. This is similar to reports in human medicine, where standardized medication error reporting strategies exist. Developing and applying similar strategies in veterinary medicine may improve patient safety and outcome.

Utility of serum amyloid A in monitoring clinical response to antimicrobial treatment in horses with bacterial pneumonia.

BACKGROUND: Serum amyloid A (SAA) is a major acute phase protein in horses which could be a useful tool for assessing clinical response to treatment of bacterial pneumonia in adult horses. OBJECTIVES: To monitor SAA concentration in response to treatment and identify associations among SAA concentration, WBC and neutrophil counts, and fibrinogen in bacterial pneumonia in adult horses. ANIMALS: Eighteen adult horses with bacterial pneumonia. METHODS: Prospective clinical study. Horses hospitalized with bacterial pneumonia were enrolled and SAA concentration and vital signs were assessed daily. SAA concentration was measured by a handheld meter. CBC and plasma fibrinogen were assessed on days 0, 1, and 2, then every 3 days until discharge. Data were not normally distributed and therefore were log transformed. Log-transformed data were analyzed and comparisons were performed on LSMeans by the 2-sided Student's t-test at the 5% level of significance. RESULTS: Geometric mean SAA concentration on day 0 was 537 µg/mL (SE 383 µg/mL). Geometric mean SAA concentration decreased significantly over time (P = .0001), peaking at day 2 (geomean 1038 µg/mL, SE 261.7 µg/mL) and decreasing until discharge. Plasma concentration of fibrinogen (P = .06), neutrophil count (P = .48), and WBC count (P = .07) did not change significantly over time. CONCLUSIONS AND CLINICAL IMPORTANCE: SAA concentration decreased significantly over the course of treatment and correlated with clinical improvement of pneumonia whereas fibrinogen, neutrophil, and WBC counts did not.

Digital health and inpatient palliative care: a cohort-controlled study.

OBJECTIVES: End of life has unacceptable levels of hospital admission and death. We aimed to determine the association of a novel digital specific system (Proactive Risk-Based and Data-Driven Assessment of Patients at the End of Life, PRADA) to modify such events. METHODS: A cohort-controlled study of those discharged alive, who died within 90 days of discharge, comparing PRADA (n=114) with standard care (n=3730). RESULTS: At 90 days, the PRADA group were more likely to die (78.9% vs 46.2%, p<0.001), had a shorter time to death (58±90 vs 178±186 days, p<0.001) but readmission (20.2% vs 37.9%, p<0.001) or death in hospital (4.4% vs 28.9%, p<0.001) was lower with reduced risk for a combined 90-day outcome of postdischarge non-elective admission or hospital death (OR 0.45, 95% CI 0.27-0.74, p<0.001). Tightening criteria with 1:1 matching (n=83 vs 83) showed persistent significant findings in PRADA contact with markedly reduced adverse events (OR 0.15, 95% CI 0.02-0.96, p<0.05). CONCLUSIONS: Being seen in hospital by a specialist palliative care team using the PRADA tool was associated with significantly improved postdischarge outcomes pertaining to those destined to die after discharge.

GP assessment of unmet need in a complex multimorbid population using a data-driven and clinical triage system: a prospective cohort study.

BACKGROUND: Patients with unmet healthcare needs are more likely to access unscheduled care. Identifying these patients through data-driven and clinical risk stratification for active case management in primary care can help address patient need and reduce demand on acute services. AIM: To determine how a proactive digital healthcare system can be used to undertake comprehensive needs analysis of patients at risk of unplanned admission and mortality. DESIGN & SETTING: Prospective cohort study of six general practices in a deprived UK city. METHOD: To identify those with unmet needs, the study's population underwent digitally-driven risk stratification into Escalated and Non-escalated groups using seven risk factors. The Escalated group underwent further stratification using GP clinical assessment into Concern and No concern groups. The Concern group underwent Unmet Needs Analysis (UNA). RESULTS: From 24 746 patients, 516 (2.1%) were triaged into the Concern group and 164 (0.7%) underwent UNA. These patients were more likely to be older (t = 4.69, P<0.001), female (X2 = 4.46, P<0.05), have a Patients At Risk of Re-hospitalisation (PARR) score ≥80 (X2 = 4.31, P<0.05), be a nursing home resident (X2 = 6.75, P<0.01), or on an end-of-life (EOL) register (X2 = 14.55, P<0.001). Following UNA, 143 (87.2%) patients had further review planned or were referred for further input. The majority of patients had four domains of need. In those who GPs would not be surprised if they died within the next few months, n = 69 (42.1%) were not on an EOL register. CONCLUSION: This study showed how an integrated, patient-centred, digital care system working with GPs can highlight and implement resources to address the escalating care needs of complex individuals.

Ingesta-associated choledocholithiasis in horses: 2 cases and literature review.

Equine ingesta-associated choledocholithiasis is a rare cause of morbidity and mortality. We describe here the clinical, gross, histologic, and microbiologic features of this condition in 2 horses and compare the features to 2 previous cases. Case 1 was a 4-y-old Thoroughbred mare with colic. Case 2 was an 18-y-old American Paint Horse mare with colic, chronic weight loss, and inappropriate mentation. Both had elevated biochemical markers of hepatocellular injury and cholestasis and were euthanized given a poor prognosis. Case 1 had a well-formed 5-cm choledocholith surrounding a piece of hay, and had chronic neutrophilic cholangiohepatitis, bridging fibrosis, and extrahepatic obstruction. Case 2 had an ill-formed choledocholith with occasional hay fragments, wood stick, and twigs, and had regionally extensive hepatocellular necrosis with mild neutrophilic cholangiohepatitis and bridging fibrosis. Enterococcus casseliflavus and Escherichia coli were isolated in both cases; Clostridium spp. were also isolated from case 2. All 4 reported cases had increased activity of cholestatic enzymes, hyperbilirubinemia, portal inflammation, and bridging fibrosis. Colic, pyrexia, leukocytosis with neutrophilia, and elevated hepatocellular enzyme activity were documented in 3 cases. Foreign material in all 4 cases was plant origin (choledochophytolithiasis), including hay (n = 2), sticks/twigs (n = 2), and grass awns (n = 1). Ingesta-associated choledocholithiasis may be considered as a cause of colic, pyrexia, and elevated cholestatic biomarkers in horses.

Risk factors associated with an outbreak of equine coronavirus at a large farm in North Carolina.

Background: Equine coronavirus (ECoV) leads to outbreaks with variable morbidity and mortality. Few previous reports of risk factors for infection are available in the literature. Objectives: To describe unique clinical findings and risk factors for infection and development of clinical disease. Animals: 135 horses on a farm affected by ECoV outbreak. Methods: Retrospective cohort study. Data obtained included age, breed, gender, activity level, housing, and feed at the onset of the outbreak. Factors were evaluated for assessment of risk of infection using simple logistic regression or Fisher's exact test. Significance was set at p ≤ 0.05. Results and findings: Forty-three of 54 (79.6%) horses tested on the farm were positive on fecal PCR for ECoV, and 17 horses (12.6%) developed clinical signs consistent with ECoV. Out of 17 horses in which the presence or absence of signs of colic was noted, 6 of 17 (35.3%) showed signs of colic. Three of these horses had small colon impactions, 2 of which required surgical intervention. Significant risk factors for having positive PCR results included being primarily stalled (OR 167.1, 95% CI 26.4-1719), housing next to a positive horse (OR 7.5, 95% CI 3.1-19.0), being in work (OR 26.9, 95% CI 4.6-281.9), being fed rationed hay vs. ad libitum (OR 1,558, 95% CI 130.8-15,593), and being fed alfalfa hay (OR 1,558, 95% CI 130.8-15,593). Conclusions and clinical importance: This report describes risk factors for ECoV infection many of which were associated with intensive management of show horses. Clinicians should be aware that clinical signs vary and can include severe colic.

General anesthesia does not induce ultrasonographic changes in the pleura of healthy adult horses anesthetized for elective magnetic resonance imaging.

OBJECTIVE: To compare thoracic ultrasonographic findings in healthy horses before and after general anesthesia for elective MRI utilizing a recently developed ultrasonographic scoring system to aid clinicians in the early identification of pneumonia following anesthesia. ANIMALS: 13 adult horses > 3 years of age. PROCEDURES: Prior to anesthesia, horses underwent a thorough physical examination, CBC, thoracic radiography, and thoracic ultrasonography. Horses were then anesthetized for elective MRI, and thoracic ultrasonography was repeated within 3 hours after recovery. Thoracic ultrasonographic findings were scored utilizing a recently developed scoring system, and scores were compared before and after anesthesia. RESULTS: There was no significant difference identified in total thoracic ultrasonography score before and after anesthesia, and there was no correlation between thoracic ultrasonography score following anesthesia and the body weight of the horse, the time recumbent, and the dependent side. CLINICAL RELEVANCE: In healthy horses undergoing anesthesia for elective imaging, there was no significant change in thoracic ultrasonographic findings 3 hours after recovery from anesthesia. These data can aid clinicians in determining the clinical significance of ultrasonographic changes in the lung in the immediate postanesthetic period.

Observational cross-sectional study of the association of poor broadband provision with demographic and health outcomes: the Wolverhampton Digital ENablement (WODEN) programme.

OBJECTIVES: The association between impaired digital provision, access and health outcomes has not been systematically studied. The Wolverhampton Digital ENablement programme (WODEN) is a multiagency collaborative approach to determine and address digital factors that may impact on health and social care in a single deprived multiethnic health economy. The objective of this study is to determine the association between measurable broadband provision and demographic and health outcomes in a defined population. DESIGN: An observational cross-sectional whole local population-level study with cohorts defined according to broadband provision. SETTING/PARTICIPANTS: Data for all residents of the City of Wolverhampton, totalling 269 785 residents. PRIMARY OUTCOMES: Poor broadband provision is associated with variation in demographics and with increased comorbidity and urgent care needs. RESULTS: Broadband provision was measured using the Broadband Infrastructure Index (BII) in 158 City localities housing a total of 269 785 residents. Lower broadband provision as determined by BII was associated with younger age (p<0.001), white ethnic status (p<0.001), lesser deprivation as measured by Index of Multiple Deprivation (p<0.001), a higher number of health comorbidities (p<0.001) and more non-elective urgent events over 12 months (p<0.001). CONCLUSION: Local municipal and health authorities are advised to consider the variations in broadband provision within their locality and determine equal distribution both on a geographical basis but also against demographic, health and social data to determine equitable distribution as a platform for equitable access to digital resources for their residents.

Comparison of thoracic ultrasonography and thoracic radiography between healthy adult horses and horses with bacterial pneumonia using a novel, objective ultrasonographic scoring system.

Background: Thoracic ultrasonography (TUS) is widely used in equine practice but comparison to radiography is limited in horses. Objectives: To validate a novel, objective scoring system for TUS in adult horses and to compare ultrasonographic and radiographic findings. Animals: 13 healthy horses and 9 with confirmed bacterial pneumonia. Methods: Prospective study in which TUS and radiography were performed on healthy horses and those with bacterial pneumonia confirmed by clinical signs and results of transtracheal wash analysis. Ultrasonography was scored utilizing a novel scoring system evaluating number of comet tail lesions, the presence or absence of pleural effusion and/or pulmonary consolidation in each intercostal space. Eighteen horses had thoracic radiographs taken that were scored by a board-certified radiologist utilizing a previously described system. Total scores were recorded and compared between control and diseased patients. Results/Findings: Ultrasonographic scores were significantly higher in the diseased group (median= 126) than in the control group (median = 20, p = 0.01). Receiver operating characteristics (ROC) analysis identified a sensitivity of 66.7% (95% CI 0.417-1) and specificity of 92.3% (95% CI 0.462-1) for the ability of ultrasonography to identify bacterial pneumonia utilizing a TUS score cutoff of 37. Conclusions and clinical importance: TUS had moderate sensitivity and high specificity for identification of bacterial pneumonia in adult horses. TUS appears to be an acceptable stand-alone imaging modality for diagnosis of bacterial pneumonia in horses when radiography is not practical.

Comparison of Fluid Analysis and Cytologic Findings of Cerebrospinal Fluid Between Three Collection Sites in Adult Equids With Neurological Disease.

Cerebrospinal fluid (CSF) is routinely collected from three sites in the horse, the atlanto-occipital (AO), atlantoaxial (AA), and lumbosacral (LS) space. A comparison between fluid analysis parameters [total protein, total nucleated cell count (TNCC), red blood cell (RBC) count, and morphologic analysis] from samples obtained at each of the three sites has not previously been performed. A retrospective analysis was performed to evaluate the differences in fluid analysis of CSF between the AO, AA, and LS sites in equids presented to a referral service for evaluation of suspected neurological disease. A total of 113 equids aged ≥1 year that underwent CSF collection between 2008 and 2020 were included. Total nucleated cell count, RBC concentration, total protein (TP), and morphologic evaluation between CSF samples obtained from the three sites were compared. When comparing all samples, LS centesis was associated with higher RBC compared to other sites (p < 0.05); TP was lower in the AA group than in the LS group (p < 0.05). Within a subset of cytologically unremarkable samples, RBC concentration was highest in LS samples (p < 0.01); TP was higher in LS samples compared to AA samples (p < 0.05) and TNCC was higher (p < 0.01) in AA and LS groups compared to the AO. In cytologically abnormal samples, there were no significant differences between sites in any parameter. Abnormal cytology was correlated with non-survival (p = 0.0002). Non-survival was associated with higher TNCC (p < 0.01). The receiver operating characteristic (ROC) curve for TNCC had an area under the curve of 0.67 (95% CI, 0.55-0.79) and indicated that a cutoff value of 24 cells/µL maximized specificity (72%) and sensitivity (54%) to predict non-survival in all horses. Positive predictive value was 45%; negative predictive value was 78%. The concentration of RBC was higher in samples from the LS site. This has clinical implications due to the importance of comparative diagnostics and its potential impact on cytologic evaluation. There were minimal differences in multiple other parameters between sites, which are likely clinically insignificant.

Acute-onset Mania in a Patient with Non-small Cell Lung Cancer.

Mania is a mood disorder characteristic of certain psychiatric conditions and is exhibited by high energy, elevated mood, irritability, insomnia, and pressured speech. Though commonly attributed to bipolar and schizoaffective disorders, mania may be precipitated by other non-psychiatric conditions, including substance abuse, medications, metabolic disturbance, and organic brain pathology. Steroid-induced mania is not uncommon and may present with a number of psychiatric symptoms. Brain tumors presenting with predominantly psychiatric symptoms are a relatively uncommon cause of mania and may persist or recede with treatment. A case of mania in a cancer patient with brain metastasis and steroid use, with no prior history of mania, is discussed herein.

Human Papillomavirus and Oropharyngeal Cancer Among Indigenous Australians: Protocol for a Prevalence Study of Oral-Related Human Papillomavirus and Cost-Effectiveness of Prevention.

BACKGROUND: Oropharyngeal cancer is an important, understudied cancer affecting Aboriginal and Torres Strait Islander Australians. The human papillomavirus (HPV) is a significant risk factor for oropharyngeal cancer. Current generation HPV vaccines are effective against the 2 most common types of high-risk HPVs in cancer (hrHPVs 16/18). OBJECTIVES: This study aims (1) to yield population estimates of oncogenic genotypes of HPV in the mouth and oropharynx of defined Aboriginal and Torres Strait Islander populations; (2) to estimate the proportion of oropharyngeal cancer attributable to HPV among these Australian citizens; (3) to estimate the impact of HPV vaccination as currently implemented on rates of oropharyngeal cancer among Aboriginal and Torres Strait Islander Australians; and (4) taking into account impact on oropharyngeal as well as cervical cancer, to evaluate efficacy and cost-effectiveness of targeted extended HPV vaccination to older ages, among our study population. METHODS: Our study design and operation is straightforward, with minimal impost on participants. It involves testing for carriage of hrHPV in the mouth and oropharynx among 1000 Aboriginal South Australians by simple saliva collection and with follow-up at 12 and 24 months, collection of sexual history at baseline, collection of information for estimating health state (quality-of-life) utilities at baseline, genotyping of viruses, predictive outcome and cost-effectiveness modeling, data interpretation and development of vaccination, and follow-up management strategies driven by the Aboriginal community. RESULTS: Participant recruitment for this study commenced in February 2018 and enrollment is ongoing. The first results are expected to be submitted for publication in 2019. CONCLUSIONS: The project will have a number of important outcomes. Synthesis of evidence will enable generation of estimates of the burden of oropharyngeal cancer among Aboriginal and Torres Strait Islander Australians and indicate the likely effectiveness and cost-effectiveness of prevention. This will be important for health services planning, and for Aboriginal health worker and patient education. The results will also point to important areas where research efforts should be focused to improve outcomes in Aboriginal and Torres Strait Islander Australians with oropharyngeal cancer. There will be a strong focus on community engagement and accounting for the preferences of individuals and the community in control of HPV-related cancers. The project has international relevance in that it will be the first to systematically evaluate prevention of both cervical and oropharyngeal cancer in a high-risk Indigenous population taking into account all population, testing, and surveillance options. REGISTERED REPORT IDENTIFIER: RR1-10.2196/10503.

Evaluating the Utility of mHealth ECG Heart Monitoring for the Detection and Management of Atrial Fibrillation in Clinical Practice.

BACKGROUND: Little attention has focused on the integration of mobile health (mHealth) technology with self-management approaches to improve the detection and management of atrial fibrillation (AF) in clinical practice. OBJECTIVE: The objective of this study was to investigate the differences between mHealth and usual care over a 6-month follow-up period among patients with a known history of atrial fibrillation. METHODS: A pilot cohort from within the larger ongoing randomized trial, iPhone® Helping Evaluate Atrial fibrillation Rhythm through Technology (iHEART), was evaluated to determine differences in detection of AF and atrial flutter (AFL) recurrence rates (following treatment to restore normal rhythm) between patients undergoing daily smartphone ECG monitoring and age and gender matched control patients. SF-36v2TM QoL assessments were administered at baseline and 6 months to a subset of the patients undergoing daily ECG monitoring. Differences between groups were assessed by t-test, Fisher's exact test, and Cox proportional hazard models. RESULTS: Among the 23 patients with smartphone ECG monitors (16 males and 7 females, mean age 55 ± 10), 14 (61%) had detection of recurrent AF/AFL versus 30% of controls. During the follow-up period, patients given smartphone ECG monitors were more than twice as likely to have an episode of recurrent AF/AFL detected (hazard ratio: 2.55; 95% CI: 1.06 - 6.11; p = 0.04). Among the 13 patients with baseline and 6 month QoL assessments, significant improvements were observed in the physical functioning (p = 0.009), role physical (p = 0.007), vitality (p = 0.03), and mental health domains (p = 0.02). CONCLUSIONS: Cardiac mHealth self-monitoring is a feasible and effective mechanism for enhancing AF/AFL detection that improves quality of life.

Measured and calculated variables of global oxygenation in healthy neonatal foals.

OBJECTIVE To assess multiple central venous and arterial blood variables that alone or in conjunction with one another reflect global oxygenation status in healthy neonatal foals. ANIMALS 11 healthy neonatal foals. PROCEDURES Central venous and arterial blood samples were collected from healthy neonatal foals at 12, 24, 36, 48, 72, and 96 hours after birth. Variables measured from central venous and arterial blood samples included oxygen saturation of hemoglobin, partial pressure of oxygen, lactate concentration, partial pressure of carbon dioxide, and pH. Calculated variables included venous-to-arterial carbon dioxide gap, estimated oxygen extraction ratio, ratio of partial pressure of oxygen in arterial blood to the fraction of inspired oxygen, bicarbonate concentration, base excess, and blood oxygen content. RESULTS Significant differences between arterial and central venous blood obtained from neonatal foals were detected for several variables, particularly partial pressure of oxygen, oxygen saturation of hemoglobin, and oxygen content. In addition, the partial pressure of carbon dioxide in central venous blood samples was significantly higher than the value for corresponding arterial blood samples. Several temporal differences were detected for other variables. CONCLUSIONS AND CLINICAL RELEVANCE Results of this study provided information about several variables that reflect global oxygenation in healthy neonatal foals. Values for these variables in healthy foals can allow for comparison with values for critically ill foals in future studies. Comparison of these variables between healthy and ill foals may aid in treatment decisions and prognosis of clinical outcome for critically ill foals.

Effects of administration of a synthetic low molecular weight/low molar substitution hydroxyethyl starch solution in healthy neonatal foals.

This study compared the effects of IV administration of isotonic fluid therapy and colloidal fluid therapy in healthy neonatal foals. Fifteen healthy neonatal foals were used in a randomized blinded prospective clinical study. Foals were randomly assigned to receive a bolus of 20 mL/kg of tetrastarch (TES) or balanced crystalloid solution. Vital parameters, colloid osmotic pressure (COP), and various clinicopathologic variables were assessed prior to infusion and at various time points up to 120 h after infusion. The treatment group (TES) had a significant increase in both COP and percentage increase in COP at 1 and 3 h. The COP was significantly lower than baseline at 3 h in the control group. No significant changes were observed in coagulation parameters in either group. Tetrastarch was effective in increasing COP for 3 h after infusion and had no notable adverse clinical effects in this group of healthy foals. Further studies are warranted regarding optimal dosing and effects in clinically ill foals.

Effets de l'administration d'une solution de substitution synthétique d'amidon hydroxyéthylé de faible poids moléculaire/faible molarité chez des poulains néonataux en santé. Cette étude a comparé les effets de l'administration IV d'une fluidothérapie isotonique et d'une fluidothérapie colloïdale chez des poulains néonataux en santé. Quinze poulains néonataux ont été utilisés dans une étude clinique prospective randomisée. Les poulains ont été assignés au hasard pour recevoir un bolus de 20 mL/kg de tétra-amidon (TEA) ou d'une solution cristalloïde équilibrée. Les paramètres vitaux, la pression osmotique colloïdale (POC) et diverses variables clinicopathologiques ont été évalués avant l'infusion et à divers moments jusqu'à 120 heures après l'infusion. Le groupe de traitement (TEA) a subi une hausse importante de la POC et une augmentation du pourcentage de POC à 1 et 3 heures dans le groupe témoin. Aucun changement significatif n'a été observé dans les paramètres de coagulation des deux groupes. Le tétra-amidon a été efficace pour l'augmentation de la POC pendant 3 heures après l'infusion et il n'a pas eu d'effets cliniques négatifs notables dans ce groupe de poulains en santé. De nouvelles études sont justifiées concernant le dosage optimal et les effets chez les poulains cliniquement malades.(Traduit par Isabelle Vallières).

Bacterial isolates, antimicrobial susceptibility patterns, and factors associated with infection and outcome in foals with septic arthritis: 83 cases (1998-2013).

OBJECTIVE: To determine clinical characteristics, clinicopathologic data, and bacterial culture and antimicrobial susceptibility results associated with septic arthritis in foals ≤ 180 days old. DESIGN: Retrospective case series. ANIMALS: 83 foals with septic arthritis. PROCEDURES: Medical records at 2 teaching hospitals between 1998 and 2013 were searched to identify those for foals ≤ 180 days old with confirmed infection of ≥ 1 synovial structure. Data extracted from the records included signalment, clinicopathologic information, bacteriologic culture and antimicrobial susceptibility results, and outcome. Data were analyzed for all foals as a single population and for foals stratified into 3 age groups (≤ 7 days, 8 to 30 days, and 31 to 180 days). RESULTS: Mean ± SD age of all foals was 18.2 ± 25 days (range, 0 to 180 days). The median number of joints affected per foal was 2 (range, 1 to 10 joints). Forty-seven of 83 (56.6%) foals survived to discharge from the hospital. Seventy antemortem synovial fluid samples underwent bacteriologic culture, of which 60 (85.7%) yielded growth. Of the 72 bacterial isolates identified, 45 (62.5%) were gram negative and 27 (375%) were gram positive. Survival rate was positively associated with plasma fibrinogen concentration and negatively associated with number of affected joints. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated the frequency with which certain bacterial agents were isolated from septic joints, which may be beneficial for the empirical treatment of septic arthritis in foals. Also, the positive association between survival rate and plasma fibrinogen concentration may have prognostic value in a clinical setting.

The Cost-Effectiveness of Postal and Telephone Methodologies in Increasing Routine Outcome Measurement Response Rates in CAMHS.

BACKGROUND: This small evaluation compared the cost effectiveness of different methods of questionnaire administration (General system improvements, postal reminders and telephone reminders) sent as part of the CORC protocol employed by three community CAMHS teams. METHOD: Return rates and costs of these different methods were recorded and compared with a 3-month baseline (during which questionnaires were distributed using existing systems) and following 3-month intervention period. RESULTS: Comparison of return rates between baseline and intervention periods indicated that administrative improvements and a centralised mailing process increased the return rate of questionnaires by 11%. A further limited increase of 16% was achieved when a postal reminder was added, whilst an additional telephone reminder significantly increased the return rate by 34%. Telephone administration and telephone follow-up to initial postal administration is more expensive overall than postal methods alone; however, the cost per return is substantially less. An initial postal mailing plus telephone reminder is predicted to provide services with more representative data on service effectiveness and acceptability than postal methods alone. CONCLUSIONS: The findings of this small scale project are useful in informing the Routine Outcome Measurement (ROM) administration protocol and highlight the importance of resourcing ROM and increasing the quality of the data collected.
