Hydration and nutrition care practices in stroke: findings from the UK and Australia.

BACKGROUND: Dehydration and malnutrition are common in hospitalised patients following stroke leading to poor outcomes including increased mortality. Little is known about hydration and nutrition care practices in hospital to avoid dehydration or malnutrition, and how these practices vary in different countries. This study sought to capture how the hydration and nutrition needs of patients' post-stroke are assessed and managed in the United Kingdom (UK) and Australia (AUS). AIM: To examine and compare current in-hospital hydration and nutrition care practice for patients with stroke in the UK and Australia. METHODS: A cross-sectional survey was conducted between April and November 2019. Questionnaires were mailed to stroke specialist nurses in UK and Australian hospitals providing post-stroke inpatient acute care or rehabilitation. Non-respondents were contacted up to five times. RESULTS: We received 150/174 (86%) completed surveys from hospitals in the UK, and 120/162 (74%) in Australia. Of the 270 responding hospitals, 96% reported undertaking assessment of hydration status during an admission, with nurses most likely to complete assessments (85%). The most common methods of admission assessment were visual assessment of the patient (UK 62%; AUS 58%), weight (UK 52%; AUS 52%), and body mass index (UK 47%; AUS 42%). Almost all (99%) sites reported that nutrition status was assessed at some point during admission, and these were mainly completed by nurses (91%). Use of standardised nutrition screening tools were more common in the UK (91%) than Australia (60%). Similar proportions of hydration management decisions were made by physicians (UK 84%; AUS 83%), and nutrition management decisions by dietitians (UK 98%; AUS 97%). CONCLUSION: Despite broadly similar hydration and nutrition care practices after stroke in the UK and Australia, some variability was identified. Although nutrition assessment was more often informed by structured screening tools, the routine assessment of hydration was generally not. Nurses were responsible for assessment and monitoring, while dietitians and physicians undertook decision-making regarding management. Hydration care could be improved through the development of standardised assessment tools. This study highlights the need for increased implementation and use of evidence-based protocols in stroke hydration and nutrition care to improve patient outcomes.

Oral care practices in stroke: findings from the UK and Australia.

AIMS: To examine current practice, perceptions of healthcare professionals and factors affecting provision for oral care post-stroke in the UK and Australia. BACKGROUND: Poor oral care has negative health consequences for people post-stroke. Little is known about oral care practice in hospital for people post-stroke and factors affecting provision in different countries. DESIGN: A cross-sectional survey. METHODS: Questionnaires were mailed to stroke specialist nurses in UK and Australian hospitals providing inpatient acute or rehabilitation care post-stroke. The survey was conducted between April and November 2019. Non-respondents were contacted up to five times. RESULTS: Completed questionnaires were received from 150/174 (86%) hospitals in the UK, and 120/162 (74%) in Australia. A total of 52% of UK hospitals and 30% of Australian hospitals reported having a general oral care protocol, with 53% of UK and only 13% of Australian hospitals reporting using oral care assessment tools. Of those using oral care assessment tools, 50% of UK and 38% of Australian hospitals used local hospital-specific tools. Oral care assessments were undertaken on admission in 73% of UK and 57% of Australian hospitals. Staff had received oral care training in the last year in 55% of UK and 30% of Australian hospitals. Inadequate training and education on oral care for pre-registration nurses were reported by 63% of UK and 53% of Australian respondents. CONCLUSION: Unacceptable variability exists in oral care practices in hospital stroke care settings. Oral care could be improved by increasing training, performing individual assessments on admission, and using standardised assessment tools and protocols to guide high quality care. The study highlights the need for incorporating staff training and the use of oral care standardised assessments and protocols in stroke care in order to improve patient outcomes.

Implementation of a patient blood management program in an Australian private hospital orthopedic unit.

BACKGROUND: Preoperative anemia in surgical patients has been linked to increased rates of allogeneic blood transfusion (ABT) and associated adverse patient outcomes such as prolonged ventilation in intensive care, increased length of hospital stay, and infections. We conducted a multifaceted implementation for orthopedic surgeons to improve preoperative patient assessment of anemia and iron deficiency to reduce perioperative blood transfusions. MATERIALS AND METHODS: Using a before-and-after study design of independent samples, we recruited a convenience sample of surgeons who performed primary total hip arthroplasty at 1 Australian private hospital. Our implementation intervention consisted of: executive support, interactive education, and peer-to-peer support to encourage adherence to the National Blood Authority's Patient Blood Management Program (PBMP) guidelines. We also used monthly reminders, e-learning access, and posters. Pre and post medical record audits evaluated preoperative blood tests, preoperative anemia, and number of blood units transfused between day of surgery until discharge. The primary outcome was an increase in the proportion of patients with preoperative blood tests undertaken prior to total hip arthroplasty surgery as recommended by the PBMP guidelines. RESULTS: Audits from 239 pre- and 263 postimplementation patients from 3 surgeons were conducted. Our primary outcome showed a significantly increased proportion of patients who had all the required preoperative tests postimplementation (0% to 94.6%; P<0.0001). Administration of ABT significantly decreased (pre: 9.2%, n=22; post: 2.3%, n=6; P=0.001) as well as the standard 2 blood units transfused (pre: 73%, n=16; post: 17%, n=1; P=0.022). The time between preoperative tests and day of surgery increased from 16 to 20 days (P<0.0001), allowing more time for physician's review of test results. CONCLUSION: Our results demonstrated successful implementation of a targeted PBMP to improve preoperative assessment to diagnose and treat anemia and/or iron deficiency prior to orthopedic surgery. This avoided unnecessary ABT and therefore mitigated potential risk to the patient.

International Uptake of a Proven Intervention to Reduce Death and Dependency in Acute Stroke: A Cross-Sectional Survey Following the QASC Trial.

BACKGROUND: Uptake of proven interventions requires dedicated resources that may only result in local implementation, thus precluding international practice change. We explored international uptake through online dissemination of the fever, sugar, and swallow (FeSS) protocols from the Quality in Acute Stroke Care (QASC) trial, which showed decreased death and dependency by 15.7% 90-day poststroke. AIMS: To identify: (a) the clinical discipline of healthcare professionals who downloaded the QASC resources; (b) the purpose for downloading; (c) successful implementation of any or all the FeSS protocols; (d) barriers to implementation; and (e) associations with self-reported successful implementation. METHODS: A cross-sectional, online survey of those who downloaded the QASC resources between October 2011 and August 2013. Associations between implementation and participant characteristics were determined. RESULTS: One-hundred and fifty-nine people from 21 countries participated. Nurses were the largest group to download the resources (n = 54, 38%), with the primary purpose to inform clinical practice (n = 97, 64%). Less than half (n = 77, 48%) downloaded, and less than a quarter (n = 38, 24%) attempted to implement all three protocols. Of those personally involved in implementation (n = 50) half reported doing so successfully for one or more protocols (n = 27, 54%) with 10 (20%) reporting successful implementation of all three protocols. Only about half (n = 13, 48%) used the proven implementation strategy with about one-third (n = 10, 29%) confirming successful uptake via audit. Implementation barriers were potential increase in nursing workload (n = 28, 56%) and lack of medical staff engagement (n = 27, 53%). Higher autonomy was associated with greater likelihood of implementation of all three protocols (p = .038). LINKING EVIDENCE TO ACTION: The QASC intervention required use of all three protocols. However, less than half downloaded them all and implementation was not guided by the proven implementation strategy. While encouraging that these resources were being used to drive practice change, piecemeal implementation of a proven intervention is unlikely to improve patient outcomes.

Testing a systematic approach to identify and prioritise barriers to successful implementation of a complex healthcare intervention.

BACKGROUND: Multiple barriers may inhibit the adoption of clinical interventions and impede successful implementation. Use of standardised methods to prioritise barriers to target when selecting implementation interventions is an understudied area of implementation research. The aim of this study was to describe a method to identify and prioritise barriers to the implementation of clinical practice elements which were used to inform the development of the T3 trial implementation intervention (Triage, Treatment [thrombolysis administration; monitoring and management of temperature, blood glucose levels, and swallowing difficulties] and Transfer of stroke patients from Emergency Departments [ED]). METHODS: A survey was developed based on a literature review and data from a complementary trial to identify the commonly reported barriers for the nine T3 clinical care elements. This was administered via a web-based questionnaire to a purposive sample of Australian multidisciplinary clinicians and managers in acute stroke care. The questionnaire addressed barriers to each of the nine T3 trial clinical care elements. Participants produced two ranked lists: on their perception of: firstly, how influential each barrier was in preventing clinicians from performing the clinical care element (influence attribute); and secondly how difficult the barrier was to overcome (difficulty attribute). The rankings for both influence and difficulty were combined to classify the barriers according to three categories ('least desirable', desirable' or 'most desirable' to target) to assist interpretation. RESULTS: All invited participants completed the survey; (n = 17; 35% medical, 35% nursing, 18% speech pathology, 12% bed managers). The barriers classified as most desirable to target and overcome were a 'lack of protocols for the management of fever' and 'not enough blood glucose monitoring machines'. CONCLUSIONS: A structured decision-support procedure has been illustrated and successfully applied to identify and prioritise barriers to target within an implementation intervention. This approach may prove to be a useful in other studies and as an adjunct to undertaking barrier assessments within individual sites when planning implementation interventions.

Telomerase activity in response to mild oxidative stress.

We have analysed telomerase activity to determine whether it can be modified when BCL-2 is endogenously overexpressed in response to a mild oxidative stress treatment as part of a survival mechanism, in contrast with an exogenous bcl-2 overexpression due to a retroviral infection. Endogenous bcl-2 overexpression was induced after a low oxidative insult of H2O2 in mice primary lung fibroblasts and L929 cell, whereas bcl-2 exogenous overexpression was performed using a retroviral infection in L929 cells. Telomerase activity was quantified in Bcl-2 overexpressing cells by the TRAP assay. When the cells were treated with different H2O2 concentrations, only those exposed to 50 µM showed increased telomerase activity. This correlates with BCL-2 expression as part of the endogenous response to mild oxidative stress. Oxidative stress generated during the toxic mechanism of chemotherapeutic drugs might induce BCL-2 increment, enhancing telomerase activity and reactivating the oncogenic process. Clinical trials should take into consideration the possibility of telomerase activation following increased BCL-2 expression when treating patients with ROS (reactive oxygen species) generation by anti-cancer drugs.
