Medical errors: Experiences, attitudes and perspectives of incoming and outgoing final-year veterinary students in the USA.

BACKGROUND: Medical errors have an impact on veterinary patient safety. Studies in human medicine suggest that students can help prevent medical errors. However, there are no studies that address the role of veterinary students in patient safety. METHODS: An electronic survey was distributed to incoming final-year (IFY) and outgoing final-year (OFY) students at the Washington State University College of Veterinary Medicine. Response data were compared between class year groups with a Fisher's exact test and Mann-Whitney U test. RESULTS: The response rate was 26.8% (70/261). Most respondents (85.7%) reported being present during a medical error, and 60% reported causing a medical error. The OFY group indicated lower agreement with documenting an error in the patient record and whether all errors should be disclosed. The IFY group felt more distress surrounding potential errors and sequential career implications. Compared with the IFY group, the OFY group agreed more that errors occur frequently in veterinary medicine and disagreed more that hospital staffing is adequate to ensure patient safety. Open responses recognised a need for communication training and identified that the OFY group regarded errors more actionably, whereas the IFY group viewed errors more emotionally. CONCLUSION: Most veterinary students will experience medical errors prior to graduation, but some lack clarity around appropriate disclosure and documentation. Additional training on medical errors and error disclosure should be provided to veterinary students.

Type and impact of clinical incidents identified by a voluntary reporting system covering 130 small animal practices in mainland Europe.

BACKGROUND: Veterinary healthcare can be a complex process and may lead to unwanted, potentially harmful patient safety incidents as a consequence, negatively impacting both the practice team and client satisfaction. The aim of this study was to identify how such incidents impact cats and dogs by analysing reports gathered in a large-scale voluntary incident reporting system. METHODS: Descriptive statistical analysis was used to study a total of 2155 incident reports, submitted by 130 practices on mainland Europe. RESULTS: Incidents caused harm in more than 40% of reports. Medication-related incidents were the most frequent type of incident recorded (40%). Treatment-related incidents were the most common type of incident causing patient harm (55%). Anaesthesia-related incidents were the most severe type of incident, resulting in patient death in 18% of these reports. Most incidents were reported from hospital wards, and a significantly higher proportion of cats were harmed by incidents compared to dogs. CONCLUSION: This study demonstrates that patients are regularly harmed by incidents, with medication-related incidents being most common. In depth understanding of incident data can help develop interventions to reduce the risk of incident recurrence.

Inadvertent injection of medetomidine in the cerebromedullaris cisterna of a dog during myelographic exam.

INTRODUCTION: A mixed breed dog was anesthetized for diagnostic myelography to investigate acute onset neck pain. Instead of contrast medium, 444 µg/kg medetomidine were inadvertently injected into the cerebromedullaris cisterna owing to a human error. Severe bradycardia, undetectable peripheral pulse, respiratory arrest and loss of pupillary, palpebral and corneal reflexes were observed immediately after injection. Profound hypothermia developed and esophageal temperature, measured 20 minutes after medetomidine injection, was 33 °C. Atipamezole at 1 mg/kg im was administered, followed by a second dose of 0,5 mg/kg iv 20 minutes thereafter. In the meantime, cardiorespiratory parameters and body temperature were monitored, and supportive care that included manually assisted pulmonary ventilation, active warming, and administration of 5 µg/kg/min dopamine was initiated. The dog's clinical condition improved within one hour from the beginning of supportive care, at which time ocular reflexes and swallowing returned, spontaneous ventilation was deemed as adequate and the trachea could be extubated. The dog was discharged in good clinical conditions five days later. Human error and distraction led to a potentially life-threatening complication in the dog of this report and could have possibly been prevented with the use of checklists and with a clearer definition of roles and responsibilities of the personnel involved prior to commencing the clinical procedure. Profound cardiovascular, respiratory, and thermoregulatory depression caused by intracisternal injection of medetomidine responded to parenteral administration of its antagonist and supportive care.

INTRODUCTION: Un chien croisé a été anesthésié pour une myélographie diagnostique afin d'étudier une douleur aiguë au niveau du cou. Au lieu du produit de contraste, 444 µg/kg de médétomidine ont été injectés par inadvertance dans la citerne cérébello-médullaire en raison d'une erreur humaine. Une bradycardie sévère, un pouls périphérique indétectable, un arrêt respiratoire et une perte des réflexes pupillaire, palpébral et cornéen ont été observés immédiatement après l'injection. Une hypothermie profonde s'est développée et la température oesophagienne, mesurée 20 minutes après l'injection de médétomidine, était de 33 °C. De l'atipamézole à 1 mg/kg im a été administré, suivi d'une seconde dose de 0,5 mg / kg iv 20 minutes après. Dans l'intervalle, les paramètres cardiorespiratoires et la température corporelle ont été surveillés et des soins de soutien comprenant une ventilation assistée manuellement, un réchauffement actif et l'administration de 5 µg/kg/min de dopamine ont été initiés. L'état clinique du chien s'est amélioré dans l'heure qui a suivi le début des soins, moment où les réflexes oculaires et la déglutition sont réapparus, la ventilation spontanée a été jugée adéquate et où on a pu procéder à l'extubation. Le chien est sorti dans de bonnes conditions cliniques cinq jours plus tard. Une erreur humaine et de la distraction ont conduit à une complication potentiellement mortelle chez le chien décrit dans ce rapport et auraient pu être évitées grâce à l'utilisation de listes de contrôle et avec une définition plus claire des rôles et des responsabilités du personnel impliqué avant le début de la procédure clinique. Une profonde dépression cardiovasculaire, respiratoire et de la thermorégulation causée par l'injection intracisternale de médétomidine a répondu à l'administration parentérale de son antagoniste et à des soins de soutien.

Frequency and classification of errors in laboratory medicine at a veterinary teaching hospital in the United States.

BACKGROUND: The accuracy of laboratory data is of utmost importance. Data regarding laboratory error in human laboratories are often extrapolated into veterinary settings. One study investigated the rate and type of errors in a European commercial veterinary laboratory, but that data might not directly apply to an educational setting. OBJECTIVES: This study determined the frequency and type of errors in laboratory medicine at a veterinary teaching hospital. METHODS: Errors associated with clinical pathology samples were recorded over two 60-day periods. The first period included a time when new students and house officers started at the veterinary school. The second time period was 6 months later. The errors were assigned to categories, and the frequency of each was calculated. Sample hemolysis, icterus, and lipemia were evaluated separately using an automated index, as these conditions could be pathologic or the result of error. Frequencies of error and hemolysis, icterus, and lipemia were assessed between the groups. RESULTS: Total error rates were 4.7% and 3.5% for the first and second periods, respectively. The frequency of each error subclassification was similar to those observed in the veterinary and human literature, with preanalytic error predominating. Statistically significant differences in the overall error rate and percentage of preanalytic errors that occurred outside of and within the laboratory were observed comparing differences between the two periods. CONCLUSIONS: The overall error rate in this veterinary teaching hospital was slightly higher than that previously reported in other settings, although a proportion of errors was as expected. Areas needing improvement were identified, and strategies to reduce error could be developed.

Turning the wrongs into rights.

Mistakes in practice can really have a negative impact on wellbeing. An error can prey on the mind, turning supposed relaxation time into rumination time. Here, Catherine Oxtoby offers a method of dealing with errors in a more productive and healthier way.

Getting it right on mistakes.

Mistakes are an inevitable part of both life and veterinary practice. But Catherine Oxtoby says there are ways to reduce the risk both of an error occurring and of it impacting on your wellbeing.

Blame and shame in the veterinary profession: barriers and facilitators to reporting significant events.

Significant event reporting is an important concept for patient safety in human medicine, but substantial barriers to the discussion and reporting of adverse events have been identified. This study explored the factors that influence the discussion and reporting of significant events among veterinary surgeons and nurses. Purposive sampling was used to generate participants for six focus groups consisting of a range of veterinary professionals of different ages and roles (mean N per group=9). Thematic analysis of the discussions identified three main themes: the effect of culture, the influence of organisational systems and the emotional effect of error. Fear, lack of time or understanding and organisational concerns were identified as barriers, while the effect of feedback, opportunity for learning and structure of a reporting system facilitated error reporting. Professional attitudes and culture emerged as both a positive and negative influence on the discussion of error. The results were triangulated against the findings in the medical literature and highlight common themes in clinician's concerns regarding the discussion of professional error. The results of this study have been used to inform the development of the 'VetSafe' tool, a web-based central error reporting system.

Jejunocystoplasty and Bilateral Ureteral Reimplantation in a Dog Following Total Cystectomy.

A 6 yr old Boston terrier presented with acute onset of vomiting and anuria 4 days following a caesarian section and ovariohysterectomy for treatment of dystocia. A total cystectomy with ligation of both ureters was diagnosed via exploratory laparotomy surgery. A jejunocystoplasty was performed in addition to a bilateral reimplantation of the ureters into the reconstructed bladder and proximal urethra. Postoperative complications included a retained ureteral stent, persistent pyelectasia, persistent hydroureters, recurrent urinary tract infections, and intermittent urinary incontinence. Four years postoperation, the dog is doing clinically well with intermittent urinary incontinence and periodic urinary tract infections. Jejunocystoplasty with bilateral ureteral reimplantation should be considered as a treatment option for dogs following total cystectomy that occurred because of a surgical error. Owners should be informed of potential complications prior to surgery.

Critical incident technique analysis applied to perianesthetic cardiac arrests at a university teaching hospital.

OBJECTIVE: To apply the critical incident technique (CIT) methodology to a series of perianesthetic cardiac arrest events at a university teaching hospital to describe the factors that contributed to cardiac arrest. STUDY DESIGN: CIT qualitative analysis of a case series. ANIMALS: A group of 16 dogs and cats that suffered a perioperative cardiac arrest between November 2013 and November 2016. METHODS: If an arrest occurred, the event was discussed among the anesthesiologists. The discussion included a description of the case, a description of the sequence of events leading up to the arrest and a discussion of what could have been done to affect the outcome. A written description of the case and the event including animal signalment and a timeline of events was provided by the supervising anesthesiologist following discussion among the anesthesiologists. Only dogs or cats were included. After the data collection period, information from the medical record was collected. A qualitative document analysis was performed on the summaries provided about each case by the supervising anesthesiologist, the medical record and any supporting documents. Each case was then classified into one or more of the following: animal, human, equipment, drug and procedural factors for cardiac arrest. RESULTS: The most common factor was animal (n=14), followed by human (n=12), procedural (n=4), drugs (n=1) and equipment (n=1). The majority (n=11) of animals had multiple factors identified. CONCLUSIONS AND CLINICAL RELEVANCE: Cardiac arrests during anesthesia at a referral teaching hospital were primarily a result of animal and human factors. Arrests because of procedural, drug and equipment factors were uncommon. Most animals experienced more than one factor and two animals arrested after a change in recumbency. Future work should focus on root cause analysis and interventions designed to minimize all factors, particularly human ones.

Misadministration of radiation therapy in veterinary medicine: a case report and literature review.

Recent technical advancements in radiation therapy have allowed for improved targeting of tumours and sparing nearby normal tissues, while simultaneously decreasing the risk for medical errors by incorporating additional safety checks into electronic medical record keeping systems. The benefits of these new technologies, however, depends on their proper integration and use in the oncology clinic. Despite the advancement of technology for treatment delivery and medical record keeping, misadministration errors have a significant impact on patient care in veterinary oncology. The first part of this manuscript describes a medical incident that occurred at an academic veterinary referral hospital, in a dog receiving a combination of stereotactic radiation therapy and full-course intensity-modulated, image-guided radiation therapy. The second part of the report is a literature review, which explores misadministration errors and novel challenges which arise with the implementation of advancing technologies in veterinary radiation oncology.
