Project description:BackgroundKnee replacement is a very effective and indispensable treatment option for end-stage knee arthritis, and the number of cases has been increasing worldwide. A replaced knee joint without patient joint awareness is thought to be the ultimate goal of artificial knees. Joint awareness reportedly correlates with patient satisfaction. Although numbness around a replaced knee is a minor but common problem, its effect on postoperative outcome is controversial. Joint awareness also is sensitive to subtle abnormalities of the joint, so it must be negatively affected by numbness. Although numbness is minor, it cannot be ignored to further improve knee replacement outcomes. This study investigated the relationship between patient-reported numbness and other patient-reported outcome measures (PROMs), including joint awareness, and kneeling. We developed a numbness score based on a 5-point Likert scale on frequency of numbness, with an intraclass correlation coefficient of 0.76 and higher scores indicating less numbness.MethodsThe numbness score, New Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS), Forgotten Joint Score-12 (FJS-12), and other clinical and radiological data from 311 patients (394 primary knee replacements) were analyzed. Kneeling ability was evaluated by using kneeling-specific items in the KSS (KSS-Kneeling).ResultsNo numbness was found in 170 knees (43.1%), and some degree of numbness was found in the remaining 224 knees (56.9%). The numbness score showed weak-to-moderate correlations with KSS-Symptoms (r = 0.44), KSS-Satisfaction (r = 0.41), KSS-Activities (r = 0.29), and all KOOS subscales (r = 0.23-0.44), and FJS-12 (r = 0.42). Multiple regression analyses suggested that midline incision positively affected the numbness score over the anteromedial incision (p = 0.04) and that a better numbness score (p = 0.001), male sex (p < 0.0001), and better postoperative knee flexion angle (0.04) positively affected kneeling.ConclusionsThe numbness score positively correlated with PROMs and positively affected kneeling. Knee replacements performed via an anteromedial incision may be at higher risk for numbness.

Project description:To design a hospital-standardised phlebotomy handover method to improve the communication between phlebotomists and doctors. To reduce delays in patient management and discharges which occur due to poor handover.Qualitative data was collected to gauge junior doctors' experiences of the current handover process. Quantitative data was collected over a two-week period across two medical wards to measure the proportion of requested bloods that could not be taken by phlebotomists that were successfully handed over to doctors. Brainstorming sessions were held with junior doctors, phlebotomists and ward staff in order to design a, cheap, effective, sustainable, hospital-wide method of handover. The chosen intervention was a red ward-based phlebotomy handover folder for phlebotomists to place stickers of unbled patients in. The folder was trialled on two medical wards. Feedback obtained helped improve the intervention before implementing it hospital-wide.Seventeen of 23 junior doctors (74%) felt that a formalised handover process would be very useful. Baseline measurement over two weeks revealed that 24/129 blood tests ordered for phlebotomists to take were not taken. Only three (13%) of these were handed over to doctors. Post-intervention, 18/106 blood tests requested were not taken. All 18 (100%) were successfully handed over to doctors.Implementation of a hospital-standardised phlebotomy handover folder dramatically improved the communication and handover between phlebotomists and doctors allowing for medical teams to take prompt action on unbled patients. This intervention will help improve patient safety, reduce delays in management/discharge and reduce the number of jobs handed over to evening on-call teams.

Project description:BackgroundMore personalized implant designs for total knee arthroplasty might optimize the clinical outcome after surgery. One of these personalized implant designs is the Persona knee implant system (Zimmer Biomet, Warsaw, Indiana, USA). The primary objective of this study was to determine patient reported outcomes and implant survivorship of the Persona Knee system used in primary total knee arthroplasty, up to two years after surgery.MethodsFrom November 2013 to July 2016 consecutive patients undergoing primary total knee arthroplasty were enrolled in a prospective observational cohort study at three centers. Preoperatively, at 6 weeks, 6 months, 1 and 2 years after surgery, patients completed the Knee Injury and Osteoarthritis Outcome Score (KOOS), the Oxford Knee Score (OKS), the Knee Society Score (KSS, 2011, modified version) and the EQ-5D. Adverse Events were captured, assessed for relationship to device, and recorded in the study database. Furthermore, physical functioning was assessed by the orthopedic surgeon. Repeated measures analyses were performed on PROM scores. Kaplan Meier was used to calculate survivorship of the Persona Knee Implant System.ResultsA total of 146 total knee arthroplasties were performed. 61% (89/146) of the patients were female and mean age was 64.7 (± 6.9) years. Two years after surgery, one patient had a revision of the polyethylene insert because of a periprosthetic joint infection. Therefore, the Kaplan-Meier survival estimate at 2 years was 0.99 (0.95-1.00 95% CI). OKS increased from 22.1 (95% CI 20.9-23.3) to 41.8 (95% CI 40.6-43.1) two years after surgery. Furthermore, all other PROMs also increased from before surgery to 2 year postoperatively.ConclusionThe Persona Knee implant is safe and effective and the clinical results up to two years after surgery are promising. PROMs results are very good; pain, function and quality of life all improved greatly after TKA. Further studies are needed to determine the long term clinical performance of the Persona prosthesis.Trial registrationClinicaltrials.gov ( NCT02337244 ). Registered June 1st, 2015. Retrospectively registered.

Project description:Blood tests are a seemingly basic investigation, but are often a vital part of directing patient management. Despite the importance of this everyday process, we indentified the potential for improvement of the current phlebotomy service in our hospital, as both junior doctors and phlebotomists reported a lack of communication and standardised practice across the wards. Resulting delays in obtaining blood test results can impact detrimentally on patient safety and management. We designed a survey which highlighted inefficient handovers and discrepancies between wards as driving factors behind this. We therefore aimed to improve communication between phlebotomists and doctors, as well as the overall organisation of the service. This took the form of the "Phlebotomy Box," a box file system offering a set location for blood stickers to be situated. The box concept was optimised on a series of medical and surgical wards, incorporating multidisciplinary feedback from relevant teams. We measured how many untaken bloods were handed over to medical staff continuously, both pre- and post implementation of the phlebotomy box. Our baseline ward demonstrated poor handover rates of untaken bloods, ranging from 0% to 40%. This increased to a consistent 100% following introduction of the Phlebotomy Box and ongoing staff education. Once optimised, the box was trialled on a further two medical wards and one surgical ward, achieving 100% handover from an initial 0% to 67%. Quantitative improvement was also reflected qualitatively in widespread staff surveys, with overwhelmingly positive support and acceptance. In summary, the Phlebotomy Box innovation has led to 100% of untaken bloods being effectively handed over. We have demonstrated a significant improvement in communication and efficiency within the phlebotomy service, with tangible benefits to patient care, as minimising time lags can prevent delays in clinical decisions. The phlebotomy box represents a simplistic, sustainable intervention that could be easily replicated in other Trusts.

Project description:In recent years medical handover has been identified as an increasingly important area for hospitals to improve upon, in light of the changes in shift patterns for doctors. Significant changes to weekday handover had recently been successfully introduced at Broomfield hospital. Weekend handover remained a concern, with an electronic and paper system being used simultaneously. Our objectives were to introduce a new electronic handover system for weekend handover at Broomfield Hospital and improve the organisation of the weekend handover meeting to promote patient safety. Doctors involved in weekend handover were surveyed using a questionnaire, to establish insufficiencies in the weekend handover process; where both the electronic ExtraMed system and paper were being used inconsistently. A new weekend handover system was introduced together with a new user-friendly electronic handover database, addressing the identified difficulties in the current system. These changes met the medical handover guidelines set by the Royal College of Physicians. Three months after the launch of the new system, doctors were re-surveyed using a modified questionnaire to assess the impact our changes had made. Before changes were implemented only 12% of doctors surveyed used the electronic system for weekend. Eighty-nine percent found sorting through jobs time consuming and 67% were handed jobs to them meant for a different grade of doctor. Only 41% were aware who to hand weekend discharges to. Subjective assessment of safety was 3.18 out of 5. The electronic system was felt to be time consuming and complicated. After execution of the new weekend handover process, 100% of doctors reported using the electronic system for weekend handover. Only 47% of doctors felt sorting through jobs was time consuming and 89% of doctors were aware who to handover weekend discharges to. Subjective assessment of the safety of weekend handover improved to 3.84 out of 5. Informal interviews on the ward revealed a high degree of satisfaction with the new weekend handover system. In conclusion we found that a structured, well organised weekend handover meeting together with an effective electronic handover system improves the quality of medical weekend handover.

Project description:ObjectivesTo identify: (1) patient-reported outcome measures (PROMs) used to evaluate symptoms, health status or quality of life following discretionary revision (or re-revision) knee joint replacement, and (2) validated joint-specific PROMs, their measurement properties and quality of evidence.Design(1) Scoping review; (2) systematic review following the COnsensus-based Standards for selection of health status Measurement INstruments (COSMIN) checklist.Data sourcesMEDLINE, Embase, AMED and PsycINFO were searched from inception to 1 July 2020 using the Oxford PROM filter unlimited by publication date or language.Eligibility criteria for selecting studiesStudies reporting on the development, validation or outcome of a joint-specific PROM for revision knee joint replacement were included.Results51 studies reported PROM outcomes using eight joint-specific PROMs. 27 out of 51 studies (52.9%) were published within the last 5 years. PROM development was rated 'inadequate' for each of the eight PROMs studied. Validation studies were available for only three joint-specific PROMs: Knee Injury and Osteoarthritis Outcome Score (KOOS), Lower Extremity Activity Scale (LEAS) and Western Ontario and McMaster Universities Arthritis Index (WOMAC). 25 out of 27 (92.6%) measurement properties were rated insufficient, indeterminate or not assessed. The quality of supporting evidence was mostly low or very low. Each of the validated PROMs was rated 'B' (potential for recommendation but require further evaluation).ConclusionJoint-specific PROMs are increasingly used to report outcomes following revision knee joint replacement, but these instruments have insufficient evidence for their validity. Future research should be directed toward understanding the measurement properties of these instruments in order to inform clinical trials and observational studies evaluating the outcomes from joint-specific PROMs.

Project description:With over 40% of children in the USA exposed to tobacco smoke, the AAP recommends tobacco smoke exposure (TSE) assessment during clinic visits. We aimed to increase the rates of TSE screening and provider counseling regarding TSE reduction using an evidence-based approach.MethodsWe conducted the project at a large pediatric pulmonology practice. Baseline caregiver surveys and medical record review of TSE documentation took place in July/August, 2019. From September 2019 to July 2021, PDSA cycles were conducted to increase TSE screening and reduce counseling.ResultsBefore starting the project, 18% of smoking caregivers acknowledged smoking in the home and 41% in the car. While caregivers strongly desired to decrease TSE (median 9.4/10 on Likert scale), physician counseling of TSE reduction was offered only to 44%. PDSA cycles led to refining our patient passport, a document used during patient intake, which increased screening of TSE from 46% to 85%. Creating an educational handout in our electronic record addressing TSE increased TSE reduction counseling from 44% to 80% of children with smokers in the home.ConclusionsIncorporating TSE screening into established nursing documentation of vital signs led to the sustained screening of TSE among children in a pediatric pulmonology practice. Embedding educational material in our electronic record and changes in clinic processes increased TSE reduction counseling. Similar changes could improve rates of counseling caregivers of other guidelines aimed to improve the children's health.

Project description:Around 110,000 people spend time in critical care units in England and Wales each year. The transition of care from the intensive care unit to the general ward exposes patients to potential harms from changes in healthcare providers and environment. Nurses working on general wards report anxiety and uncertainty when receiving patients from critical care. An innovative form of enhanced capability critical care outreach called 'iMobile' is being provided at King's College Hospital (KCH). Part of the remit of iMobile is to review patients who have been transferred from critical care to general wards. The iMobile team wished to improve the quality of critical care discharge summaries. A collaborative evidence-based quality improvement project was therefore undertaken by the iMobile team at KCH in conjunction with researchers from King's Improvement Science (KIS). Plan, Do, Study, Act (PDSA) methodology was used. Three PDSA cycles were undertaken. Methods adopted comprised: a scoping literature review to identify relevant guidelines and research evidence to inform all aspects of the quality improvement project; a process mapping exercise; informal focus groups / interviews with staff; patient story-telling work with people who had experienced critical care and subsequent discharge to a general ward; and regular audits of the quality of both medical and nursing critical care discharge summaries. The following behaviour change interventions were adopted, taking into account evidence of effectiveness from published systematic reviews and considering the local context: regular audit and feedback of the quality of discharge summaries, feedback of patient experience, and championing and education delivered by local opinion leaders. The audit results were mixed across the trajectory of the project, demonstrating the difficulty of sustaining positive change. This was particularly important as critical care bed occupancy and through-put fluctuates which then impacts on work-load, with new cohorts of staff regularly passing through critical care. In addition to presenting the results of this quality improvement project, we also reflect on the lessons learned and make suggestions for future projects.

Project description:There has been a proliferation in the development of indwelling neuromodulatory devices with varied safety recommendations, making it difficult for providers to remain up-to-date. This deficit presents an opportunity for significant improvement in patient safety.MethodsWe performed a search for monopolar electrocautery and magnetic resonance imaging safety recommendations for several indwelling neuromodulatory devices. We developed a questionnaire followed by an educational compendium and a posttest for 50 care providers.ResultsOverall, there was a poor performance on the pretest (mean 39%, SD 19%) but significant improvement on the posttest (mean 71%, SD 16%), P < 0.0001. We placed the educational compendium that included all manufacturer recommendations in the operating room for easy reference. A 2.4 times decrease in the case start times of vagus nerve stimulator cases is evidence of its effectiveness.ConclusionsThe authors highlight the lack of knowledge about manufacturer safety recommendations for indwelling neurosurgical devices, which led to the creation of operating room supplements and educational devices.

Project description:RATIONALE, AIMS, AND OBJECTIVES:The work is a part of a project about the application of the Lean Six Sigma to improve health care processes. A previously published work regarding the hip replacement surgery has shown promising results. Here, we propose an application of the DMAIC (Define, Measure, Analyse, Improve, and Control) cycle to improve quality and reduce costs related to the prosthetic knee replacement surgery by decreasing patients' length of hospital stay (LOS) METHODS: The DMAIC cycle has been adopted to decrease the patients' LOS. The University Hospital "Federico II" of Naples, one of the most important university hospitals in Southern Italy, participated in this study. Data on 148 patients who underwent prosthetic knee replacement between 2010 and 2013 were used. Process mapping, statistical measures, brainstorming activities, and comparative analysis were performed to identify factors influencing LOS and improvement strategies. RESULTS:The study allowed the identification of variables influencing the prolongation of the LOS and the implementation of corrective actions to improve the process of care. The adopted actions reduced the LOS by 42%, from a mean value of 14.2 to 8.3 days (standard deviation also decreased from 5.2 to 2.3 days). CONCLUSIONS:The DMAIC approach has proven to be a helpful strategy ensuring a significant decreasing of the LOS. Furthermore, through its implementation, a significant reduction of the average costs of hospital stay can be achieved. Such a versatile approach could be applied to improve a wide range of health care processes.
