Vital signs monitoring on general wards: clinical staff perceptions of current practices and the planned introduction of continuous monitoring technology

OBJECTIVE Early detection of patient deterioration and prevention of adverse events are key challenges to patient safety. This study investigated clinical staff perceptions of current monitoring practices and the planned introduction of continuous monitoring devices on general wards. DESIGN Multi-method study comprising structured surveys, in-depth interviews and device trial with log book feedback. SETTING Two general wards in a large urban teaching hospital in Sydney, Australia. PARTICIPANTS Respiratory and neurosurgery nursing staff and two doctors. RESULTS Nurses were confident about their abilities to identify patients at risk of deterioration, using a combination of vital signs and visual assessment. There were concerns about the accuracy of current vital signs monitoring equipment and frequency of intermittent observation. Both the nurses and the doctors were enthusiastic about the prospect of continuous monitoring and perceived it would allow earlier identification of patient deterioration; provide reassurance to patients; and support interdisciplinary communication. There were also reservations about continuous monitoring, including potential decrease in bedside nurse-patient interactions; increase in inappropriate escalations of patient care; and discomfort to patients. CONCLUSIONS While continuous monitoring devices were seen as a potentially positive tool to support the identification of patient deterioration, drawbacks, such as the potential for reduced patient contact, revealed key areas that will require close surveillance following the implementation of devices. Training and improved interdisciplinary communication were identified as key requisites for successful implementation.

Stepped-wedge cluster randomised controlled trial to assess the effectiveness of an electronic medication management system to reduce medication errors, adverse drug events and average length of stay at two paediatric hospitals: a study protocol.

Introduction Medication errors are the most frequent cause of preventable harm in hospitals. Medication management in paediatric patients is particularly complex and consequently potential for harms are greater than in adults. Electronic medication management (eMM) systems are heralded as a highly effective intervention to reduce adverse drug events (ADEs), yet internationally evidence of their effectiveness in paediatric populations is limited. This study will assess the effectiveness of an eMM system to reduce medication errors, ADEs and length of stay (LOS). The study will also investigate system impact on clinical work processes. Methods and analysis A stepped-wedge cluster randomised controlled trial (SWCRCT) will measure changes pre-eMM and post-eMM system implementation in prescribing and medication administration error (MAE) rates, potential and actual ADEs, and average LOS. In stage 1, 8 wards within the first paediatric hospital will be randomised to receive the eMM system 1 week apart. In stage 2, the second paediatric hospital will randomise implementation of a modified eMM and outcomes will be assessed. Prescribing errors will be identified through record reviews, and MAEs through direct observation of nurses and record reviews. Actual and potential severity will be assigned. Outcomes will be assessed at the patient-level using mixed models, taking into account correlation of admissions within wards and multiple admissions for the same patient, with adjustment for potential confounders. Interviews and direct observation of clinicians will investigate the effects of the system on workflow. Data from site 1 will be used to develop improvements in the eMM and implemented at site 2, where the SWCRCT design will be repeated (stage 2). Ethics and dissemination The research has been approved by the Human Research Ethics Committee of the Sydney Childrens Hospitals Network and Macquarie University. Results will be reported through academic journals and seminar and conference presentations. Trial registration number Australian New Zealand Clinical Trials Registry (ANZCTR) 370325.

Longitudinal study of user experiences of a CPOE system in a pediatric hospital

OBJECTIVE To explore the views of nurses and doctors during the early stages of implementation of a computerized provider order entry (CPOE) system in a pediatric hospital and to examine changes in perceptions and reported behaviors as use of the CPOE system became routine. METHODS Semi-structured interviews were undertaken at four time points following CPOE implementation: during week one, week three, week six and then six months following implementation. In total, 122 users were interviewed. Interviews were audio-recorded and transcribed verbatim. Emergent themes were mapped to the Extended Technology Acceptance Model (e-TAM). RESULTS Initial perceptions were driven by unfamiliarity with the system. As users became more proficient and efficient in using the CPOE system, additional safety benefits become apparent. However, accompanying increased reports of benefits were reports of usability problems and new types of errors arising from CPOE use. Reports of workarounds appeared for the first time at 6-month interviews. These workarounds were adopted to allow routine work to continue and to attenuate some of the perceived negative consequences of CPOE, including delayed medications and reduced patient interaction. CONCLUSION This study is one of the first to examine changes in perceptions of CPOE at multiple points, demonstrating the trajectory of changes in views over time. It provides new information about the time point at which workarounds begin to be embedded in practice and are potentially most receptive to identification and remediation. It suggests an adaptive implementation and support program would be beneficial, as reported difficulties and concerns change during the first six months of use.

Making sense of a haemolysis monitoring and reporting system: a nationwide longitudinal multimethod study of 68 Australian laboratory participant organisations

Abstract Background: The key incident monitoring and management systems (KIMMS) quality assurance program monitors incidents in the pre- and postanalytical phases of testing in medical laboratories. Haemolysed specimens have been found to be the most frequent preanalytical error and have major implications for patient care. The aims of this study were to assess the suitability of KIMMS for quality reporting of haemolysis and to devise a meaningful method for reporting and monitoring haemolysis. Methods: A structured survey of 68 Australian KIMMS laboratory participant organisations was undertaken. Quarterly haemolysis reports (2011–2014) were analysed. Results: Among 110 million accessions reported, haemolysis rates varied according to the reporting methods that participants used for assigning accessions (16% of participants reported haemolysis by specimen and 83% reported by episode) and counting haemolysis rejections (61% by specimen, 35% by episode and 3% by test). More than half of the participants (56%) assigned accessions by episode and counted rejections by specimen. For this group, the average haemolysis rate per 100,000 episodes was 177 rejected specimens with the average rate varying from 100 to 233 over time. The majority of participants (91%) determined rejections using the haemolysis index. Two thirds of participants (66%) recorded the haemolysis manually in laboratory information systems. Conclusions: KIMMS maintains the largest longitudinal haemolysis database in the world. However, as a means of advancing improvements in the quality of the preanalytical laboratory process, there is a need to standardise reporting methods to enable robust comparison of haemolysis rejection rates across participant laboratories.

Key factors influencing the incidence of hemolysis: A critical appraisal of current evidence

Abstract Hemolysis is a leading cause of pre-analytical laboratory errors. The identification of contributing factors is an important step towards the development of effective practices to reduce and prevent hemolysis. We performed a review of PUBMED, Embase, Medline and CINAHL to identify articles published between January 2000 and August 2016 that identified factors influencing in vitro hemolysis rates. The 40 studies included in this review provide excellent evidence that hemolysis rates are higher in Emergency Departments (EDs), for non-antecubital draws, for specimens drawn using an intravenous catheter compared to venipuncture and for samples transported by pneumatic tube compared to by hand. There is also good evidence that hemolysis rates are higher when specimens are not collected by professional phlebotomists, larger volume specimen tubes are used, specimen tubes are filled less than halfway and tourniquet time is greater than one minute. The results of this review suggest that hospitals and clinical laboratories should consider deploying phlebotomists in EDs, drawing all blood through a venipuncture, using the antecubital region as the optimum blood collection site and transporting specimens by laboratory assistant/other personnel, or if this in not practical, ensuring that pneumatic transport systems are validated, maintained and monitored. Studies also recommend making hemolysis a hospital-wide issue and ensuring high-quality staff training and adherence to standard operating procedures to reduce hemolysis rates. Awareness of the factors that influence hemolysis rates, and adoption of strategies to mitigate these risk factors, is an important step towards creating quality practices to reduce hemolysis rates and improve the quality of patient care.

The quality, safety and governance of telephone triage and advice services – an overview of evidence from systematic reviews

BackgroundTelephone triage and advice services (TTAS) are increasingly being implemented around the world. These services allow people to speak to a nurse or general practitioner over the telephone and receive assessment and healthcare advice. There is an existing body of research on the topic of TTAS, however the diffuseness of the evidence base makes it difficult to identify key lessons that are consistent across the literature. Systematic reviews represent the highest level of evidence synthesis. We aimed to undertake an overview of such reviews to determine the scope, consistency and generalisability of findings in relation to the governance, safety and quality of TTAS.MethodsWe searched PubMed, MEDLINE, EMBASE, CINAHL, Web of Science and the Cochrane Library for English language systematic reviews focused on key governance, quality and safety findings related to telephone based triage and advice services, published since 1990. The search was undertaken by three researchers who reached consensus on all included systematic reviews. An appraisal of the methodological quality of the systematic reviews was independently undertaken by two researchers using A Measurement Tool to Assess Systematic Reviews.ResultsTen systematic reviews from a potential 291 results were selected for inclusion. TTAS was examined either alone, or as part of a primary care service model or intervention designed to improve primary care. Evidence of TTAS performance was reported across nine key indicators – access, appropriateness, compliance, patient satisfaction, cost, safety, health service utilisation, physician workload and clinical outcomes. Patient satisfaction with TTAS was generally high and there is some consistency of evidence of the ability of TTAS to reduce clinical workload. Measures of the safety of TTAS tended to show that there is no major difference between TTAS and traditional care.ConclusionsTaken as a whole, current evidence does not provide definitive answers to questions about the quality of care provided, access and equity of the service, its costs and outcomes. The available evidence also suggests that there are many interactional factors (e.g., relationship with other health service providers) which can impact on measures of performance, and also affect the external validity of the research findings.

User perceptions of the implementation of an electronic medication management system in a paediatric setting

The roll-out of a hospital-wide electronic medication management system (eMMS) is a challenging task, requiring planning, coordination, communication and change management. This research aimed to explore the views of doctors and nurses about the strategy used to implement an eMM system in a paediatric hospital. Semi-structured interviews were performed during the first week of the implementation on each ward, and were then followed up three and six weeks post implementation. In total, 90 users (60 nurses and 30 doctors) were asked about their impressions of the implementation, as well as their perceptions of training and IT support. Qualitative thematic analysis was performed by three researchers. Most users perceived the implementation of the eMM to be positive overall. Although perceptions of the implementation process remained largely consistent across the six weeks, users identified several areas where improvements were needed, especially early in implementation, including resources, planning, roll-out strategy and training. These findings are useful for future implementations of eMM systems in paediatric hospitals.

Capturing Accurate and Useful Information on Medication-Related Telenursing Triage Calls.

Registered nurses providing telenursing triage and advice services record information on the medication related calls they handle. However the quality and consistency of these data were rarely examined. Our aim was to examine medication related calls made to the healthdirect advice service in November 2014, to assess their basic characteristics and how the data entry format influenced information collected and data consistency. Registered nurses selected the patient question type from a range of categories, and entered the medications involved in a free text field. Medication names were manually extracted from the free text fields. We also compared the selected patient question type with the free text description of the call, in order to gauge data consistency. Results showed that nurses provided patients with advice on medication-related queries in a timely matter (the median call duration of 9 minutes). From 1835 calls, we were able to identify and classify 2156 medications into 384 generic names. However, in 204 cases (11.2% of calls) no medication name was entered. A further 308 (15.0%) of the medication names entered were not identifiable. When we compared the selected patient question with the free text description of calls, we found that these were consistent in 63.27% of cases. Telenursing and triage advice services provide a valuable resource to the public with quick and easily accessible advice. To support nurses provide quality services and record accurate information about the queries, appropriate data entry format and design would be beneficial.
