Applying the lessons of design thinking: a unique programme of care for acutely unwell, community-dwelling COVID-19 patients.

BACKGROUND: The COVID-19 pandemic limited access to primary care and in-person assessments requiring healthcare providers to re-envision care delivery for acutely unwell outpatients. Design thinking methodology has the potential to support the robust evolution of a new clinical model. AIM: To demonstrate how design thinking methodology can rapidly and rigorously create and evolve a safe, timely, equitable and patient-centred programme of care, and to share valuable lessons for effective implementation of design thinking solutions to address complex problems. METHOD: We describe how design thinking methodology was employed to create a new clinical model of care. Using the example of a novel telemedicine programme to support acutely unwell, community-dwelling COVID-19-positive patients called the London Urgent COVID-19 Care Clinic (LUC3), we show how continuous quality outcomes (safety, timeliness, equity and patient-centredness), as well as patient experience survey responses, can drive iterative changes in programme delivery. RESULTS: The inspiration phase identified four key needs for this patient population: monitoring COVID-19 signs and symptoms; self-managing COVID-19 symptoms; managing other comorbidities in the setting of COVID-19; and escalating care as needed. Guided by these needs, a cross-disciplinary stakeholder group was engaged in the ideation and implementation phases to create a unique and comprehensive telemedicine programme (LUC3). During the implementation phase, LUC3 assessed 2202 community-based patients diagnosed with acute COVID-19; the collected quality outcomes and end-user feedback led to evolution of programme delivery. CONCLUSION: Design thinking methodology provided an essential framework and valuable lessons for the development of a safe, equitable, timely and patient-centred telemedicine care programme. The lessons learnt here-the importance of inclusive collaboration, using empathy to guide equity-focused interventions, leveraging continuous metrics to drive iteration and aiming for good-if-not-perfect plans-can serve as a road map for using design thinking for targeted healthcare problems.

Evaluating the safety and effectiveness of a nurse-led outpatient virtual IV vancomycin monitoring clinic: a retrospective cohort study.

BACKGROUND: Outpatient parenteral antimicrobial therapy (OPAT) with vancomycin is a common treatment modality for certain Gram-positive infections. Data regarding the safety of various models of delivery are limited. OBJECTIVES: To review outcomes of a nurse-led OPAT vancomycin monitoring service. METHODS: This was a retrospective cohort study of consecutive patients referred to a nurse-led OPAT vancomycin clinic from December 2015 to March 2018. Patients were administered IV vancomycin in the home with active laboratory monitoring of vancomycin trough levels, renal function and complete blood count using an integrated electronic database linked with community laboratories (virtual vancomycin clinic, VVC). Monitoring was coordinated by nurses with physician approval of recommended dosing changes. Data were extracted from the electronic medical record. Demographics; clinical indication; microbial aetiology; culture source; antimicrobial regimen(s); serum creatinine and vancomycin trough values; initiation, discharge and completion dates; hospitalizations; adverse events; and outcomes were all evaluated. RESULTS: Two hundred and seventy-five patients underwent a total of 301 courses of OPAT with vancomycin; 285 courses were completed. The rate of treatment discontinuation due to adverse effects was 33/301 (11.0%), with 15/33 (45.5%) being due to renal adverse effects (15/301 [5.0%] of episodes). Two of 15 (18.2%) patients developed stage 2 acute kidney injury (AKI), and no patients had stage 3 AKI or required haemodialysis. Nine of 301 (3.0%) required readmission for treatment failure. Nursing costs associated with monitoring were $63.93 CAD/patient ($48.43 USD). CONCLUSIONS: A nurse-led VVC was a safe, effective and inexpensive modality for administering outpatient vancomycin.

The many faces of ocular syphilis: case-based update on recognition, diagnosis, and treatment.

In recent years, syphilis (Treponema pallidum) has become increasingly prevalent in Canada, and as a result, rates of ocular syphilis are also rising. Classically, syphilis was seen primarily in men who have sex with men; now, it is increasingly seen in people of all age groups, sexes, and sexual orientations. We present a series of 26 cases of ocular syphilis from London, Ontario, 5 of which are discussed in detail to illustrate the varied presentations and diagnostic challenges of ocular syphilis. The presentations include uveitis, iris granuloma (gumma), retinitis (acute syphilitic posterior placoid chorioretinitis), vasculitis, optic neuritis, and serous retinal detachment. The 5 cases are mostly middle-aged heterosexual men and women without the typical risk factors that would alert the examiner to suspect syphilis. We emphasize the importance of testing for syphilis when assessing and treating inflammatory eye disease, regardless of demographics and known risk factors, given the increasing prevalence of this disease. Diagnosis of syphilis relies on serologic testing, which is complex and has undergone significant changes from historical reliance on the Venereal Disease Research Laboratory test. We provide an overview of the strategy and rationale for modern serologic testing. The mainstay of treatment remains intravenous penicillin G, with alternative antibiotics (e.g., ceftriaxone) being less effective.

The first described case of Lodderomyces elongisporus meningitis.

We describe the first documented case of meningitis caused by Lodderomyces elongisporus. Identification of L. elongisporus was made on the basis of an arachnoid biopsy with pathology samples sent for fungal internal transcribed spacer sequencing after multiple central nervous system (CNS) fungal culture specimens were negative. After final diagnosis, treatment was transitioned from amphotericin to fluconazole, which, combined with insertion of lumbar drain followed by a permanent ventriculopleural shunt, resulted in significant clinical improvement. Our report reviews the literature of (1) cases of L. elongisporus, which almost exclusively describe fungemia or endocarditis; (2) CNS infections caused by Candida parapsilosis, an organism with which L. elongisporus was previously conflated; and (3) management of fungal meningitis-associated hydrocephalus.

Les chercheurs décrivent le premier cas répertorié de méningite causée par le Lodderomyces elongisporus. Ils ont dépisté le L. elongisporus après avoir effectué une biopsie de l'arachnoïde et envoyé les prélèvements pathologiques au séquençage de l'espaceur transcrit interne fongique après l'obtention de multiples cultures fongiques négatives. Après le diagnostic définitif, le traitement d'amphotéricine a été remplacé par du fluconazole qui, combiné à l'insertion d'un drain lombaire suivie par l'installation d'une dérivation ventriculopleurale permanente, a favorisé une amélioration clinique évidente. L'analyse bibliographique a permis d'extraire 1) des cas de L. elongisporus, qui ont été observés presque exclusivement dans des cas de fongémie auparavant, 2) des infections du système nerveux central causées par le Candida parapsilosis, un organisme avec lequel le L. elongisporus a déjà été confondu et 3) la prise en charge de l'hydrocéphalie associée à la méningite fongique.

Impact of Reported Beta-Lactam Allergy on Inpatient Outcomes: A Multicenter Prospective Cohort Study.

BACKGROUND: Reported allergy to beta-lactam antibiotics is common and often leads to unnecessary avoidance in patients who could tolerate these antibiotics. We prospectively evaluated the impact of these reported allergies on clinical outcomes. METHODS: We conducted a trainee-led prospective cohort study to determine the burden and clinical impact of reported beta-lactam allergy on patients seen by infectious diseases consultation services at 3 academic hospitals. The primary outcome was a composite measure of readmission for the same infection, acute kidney injury, Clostridium difficile infection, or drug-related adverse reactions requiring discontinuation. Predictors of interest were history of beta-lactam allergy and receipt of preferred beta-lactam therapy. RESULTS: Among 507 patients, 95 (19%) reported beta-lactam allergy; preferred therapy was a beta-lactam in 72 (76%). When beta-lactam therapy was preferred, 25 (35%) did not receive preferred therapy due to their report of allergy even though 13 (52%) reported non-severe prior reactions. After adjustment for confounders, patients who did not receive preferred beta-lactam therapy were at greater risk of adverse events (adjusted odds ratio [aOR], 3.1; 95% confidence interval [CI], 1.28-7.89) compared with those without reported allergy. In contrast, patients who received preferred beta-lactam therapy had a similar risk of adverse events compared with patients not reporting allergy (aOR, 1.33; 95% CI, .62-2.87). CONCLUSIONS: Avoidance of preferred beta-lactam therapy in patients who report allergy is associated with an increased risk of adverse events. Development of inpatient programs aimed at accurately identifying beta-lactam allergies to safely promote beta-lactam administration among these patients is warranted.

Morning handover of on-call issues: opportunities for improvement.

IMPORTANCE: Handover is the process of transferring pertinent patient information and clinical responsibility between health care practitioners. Few studies have examined morning handover from the overnight trainee to the daytime team. OBJECTIVE: To characterize current morning handover practices in 2 academic medical centers by assessing the frequency of omissions of clinically important overnight issues during morning handover and identifying factors that influence the occurrence of such omissions. DESIGN, SETTING, AND PARTICIPANTS: A prospective, point-prevalence study was conducted in the general internal medicine wards of 2 tertiary care academic medical centers in Toronto, Ontario, Canada, in 2012 and 2013. Participants included on-call third-year medical students and first- and second-year residents. MAIN OUTCOMES AND MEASURES: Completeness of morning handover of clinically important overnight issues identified using a targeted medical records review and processes of morning handover characterized by direct observation. RESULTS: We identified 141 clinically important overnight issues during 26 days of observation. The on-call trainee omitted 40.4% (95% CI, 32.3%-48.5%) of clinically important issues during morning handover and did not document any information in the patient's medical record for 85.8% (95% CI 80.1%-91.6%) of these issues. By univariate analysis, running the list patient-by-patient (ie, the entire team discusses each patient) (OR, 4.32; 95% CI, 1.94-9.60; P < .001) and using a dedicated handover location (OR, 2.61; 95% CI, 1.30-5.22; P = .007) positively correlated with handover of an issue taking place, whereas distractions in the meeting area inversely correlated with the likelihood of handover of an issue taking place (OR, 0.96 for every increase in 1 distraction; 95% CI, 0.93-0.98; P = .002). Using a multivariate mixed-effects model, only running the list remained as an independent predictor of the handover of an issue (OR, 3.80; 95% CI, 1.25-11.49; P = .02). CONCLUSIONS AND RELEVANCE: On-call trainees omit numerous clinically important issues when handing over to the daytime team. Training programs should introduce educational activities and workflow changes, and provide dedicated time and a distraction-free environment, to improve handover of on-call issues.
