RESUMO
Background and Objectives: The Investigation of Palpitations in the ED (IPED) study showed that a smartphone-based event recorder increased the number of patients in whom an electrocardiogram (ECG) was captured during symptoms over five-fold to more than 55% at 90 days compared to standard care and concluded that this safe, non-invasive and easy-to-use device should be considered part of on-going care to all patients presenting acutely with unexplained palpitations or pre-syncope. This study reports the process of establishing a smartphone palpitation and pre-syncope ambulatory care Clinic (SPACC) service. Materials and Methods: A clinical standard operating procedure (SOP) was devised, and funding was secured through a business case for the purchase of 40 AliveCor devices in the first instance. The clinic was launched on 22 July 2019. Results: Between 22 July 2019 and 31 October 2019, 68 patients seen in the emergency departments (EDs) with palpitations or pre-syncope were referred to SPACC. Of those, 30 were male and 38 were female, and the mean age was 45.8 years old (SD 15.1) with a range from 18 years old to 80 years old. A total of 50 (74%) patients underwent full investigation. On the first assessment, seven (10%) patients were deemed to have non-cardiac palpitations and were not fitted with the device. All patients who underwent full investigation achieved symptomatic rhythm correlation most with sinus rhythm, ventricular ectopics, or bigeminy. A symptomatic cardiac dysrhythmia was detected in six (8.8%) patients. Three patients had supraventricular tachycardia (4%), two had atrial fibrillation (3%), and one had atrial flutter (2%). Qualitative feedback from the SPACC team suggested several areas where improvement to the clinic could be made. Conclusion: We believe a smartphone palpitation service based on ambulatory care is simple to implement and is effective at detecting cardiac dysrhythmia in ED palpitation patients.

BACKGROUND: Delays in achievement of target mean arterial pressure (MAP) have been associated with increased mortality in patients with septic shock. Vasopressin may be added to norepinephrine to raise MAP or decrease norepinephrine dosage. The purpose of this study was to determine whether early initiation of vasopressin to norepinephrine resulted in a reduced time to target MAP compared to norepinephrine monotherapy. METHODS: This retrospective cohort study compared early addition of vasopressin within 4 hours of septic shock onset to norepinephrine versus initial norepinephrine monotherapy in medically, critically ill patients with septic shock admitted from May 2014 to October 2015. Time to goal MAP was compared using Student t test and examined with Kaplan-Meier curves. Changes in Sequential Organ Failure Assessment (SOFA) scores were evaluated with Wilcoxon rank sum test. RESULTS: Each group contained 48 patients. Mean arterial pressure (61.5 vs 58.6 mm Hg) and intravenous fluid volume received at vasopressor initiation (14.3 vs 25.2 hours, P = .014) were similar. Patients started on early vasopressin achieved and maintained goal MAP sooner (6.2 vs 9.9 hours, P = .023), experienced greater reductions in SOFA scores at 72 hours (-4 vs -1, P = .012), and had shorter hospital durations (343 vs 604 hours, P = .014). Not initiating early vasopressin trended toward an association with increased time to goal MAP (P = .067). CONCLUSION: Early initiation of vasopressin in patients with septic shock may achieve and maintain goal MAP sooner and resolve organ dysfunction at 72 hours more effectively than later or no initiation.

BACKGROUND: Guidance for the discontinuation of vasopressors in the recovery phase of septic shock is limited. Norepinephrine is more easily titrated; however, septic shock is a vasopressin deficient state, which exogenous vasopressin endeavors to resolve. Discontinuation of vasopressin before norepinephrine may result in clinically significant hypotension. METHODS: This retrospective, cohort study compared discontinuation of norepinephrine and vasopressin in medically, critically ill patients in the recovery phase of septic shock from May 2014 to June 2016. Difference in clinically significant hypotension after norepinephrine or vasopressin discontinuation was evaluated with χ2 test. Linear regression was performed, examining the effect of agent discontinuation on clinically significant hypotension. Baseline variables were examined for a bivariate relationship with clinically significant hypotension; those with P < .2 were included in the model. RESULTS: Vasopressin was discontinued first or last in 62 and 92 patients, respectively. Sequential Organ Failure Assessment scores at 72 hours (7.9 vs 7.6, P = .679) were similar. In unadjusted analysis, when vasopressin was discontinued first, more clinically significant hypotension developed (10.9% vs 67.8%, P < .001). There was no difference in intensive care unit (174 vs 216 hours, P = .178) or hospital duration (470 vs 473 hours, P = .977). In adjusted analyses, discontinuing vasopressin first was associated with increased clinically significant hypotension (odds ratio [OR]: 13.837, 95% confidence interval [CI]: 3.403-56.250, P < .001) but not in-hospital (OR: 0.659, 95% CI: 0.204-2.137, P = .488) or 28-day mortality (OR: 0.215, 95% CI: 0.037-1.246, P = .086). CONCLUSION: Adult patients receiving norepinephrine and vasopressin in the resolving phase of septic shock may be less likely to develop clinically significant hypotension if vasopressin is the final vasopressor discontinued.

BACKGROUND: The opioid epidemic in the United States is a problem that has developed over decades. While clinical, regulatory, and legislative changes have been implemented to combat this issue, changes will not be immediate. Moreover, the changes that have been carried out may have unintended negative consequences such as increased use of illicit opioids (e.g., heroin and synthetics) and challenges in effective and appropriate pain management. OBJECTIVES: This review focuses on the last three decades and presents key changes the United States has seen in the use of opioids. Conclusions/Importance: There have been numerous policy changes and programs aimed at decreasing opioid use and abuse in the United States; however, it will take a major shift in the mindset of clinicians, the general public, and policy makers to alleviate this epidemic.

A 30-year-old male with a past history of polysubstance use presents to a drug rehabilitation facility after cocaine and heroin use just prior to arrival. While drinking at a water fountain at the facility, he became unresponsive. He was discovered to have an oxygen saturation of 50% on room air with an improvement to 87% on non-rebreather masks. Arterial blood gas revealed a methemoglobin level of 45.8%. The patient was given methylene blue with a repeat methemoglobin level of 0.00% within six hours. We attribute this presentation to local anesthetic-adulterated cocaine, a well-documented cause of methemoglobinemia in the United Kingdom rarely described in the United States.
RESUMO
BACKGROUND: There is significant underutilisation of allocated health service resources when a scheduled flexible cystoscopy (FC) is cancelled because a pre-cystoscopy urinalysis (PCU) suggests "infection", despite patients being asymptomatic for urinary tract infection (UTI). OBJECTIVE: To evaluate the risk of UTI or urinary sepsis when FC is performed in asymptomatic patients with a PCU positive for leucocyte esterase and/or nitrites. DESIGN SETTING AND PARTICIPANTS: A prospective cohort study was conducted in a high-volume UK centre recruiting all patients undergoing outpatient FC. INTERVENTION: A protocol was developed to guide response to PCU performed prior to FC, which was performed regardless of the result, unless patients were symptomatic for UTI. All patients completed a questionnaire to identify risk factors and were followed up via a telephone survey and a review of electronic clinical records. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Post-FC UTI was defined as hospital admission with UTI/urinary sepsis or if patients were symptomatic for UTI with receipt of antibiotics or with positive urine culture and sensitivity. An analysis of the association was performed. RESULTS AND LIMITATIONS: An initial pilot study confirmed the safety and feasibility of our protocol. Of 1996 patients, 136 (6.8%) developed a UTI by our definition, with 51 (2.6%) having a culture-proven infection. The risk was higher in patients with a positive PCU (odds ratio [OR] 1.61, 95% confidence interval [CI] = 1.07-2.40, p = 0.02), history of UTI (OR 1.72, 95% CI = 1.09-2.73, p = 0.02), or a bladder tumour on FC (OR 2.22, 95% CI = 1.27-3.90, p = 0.005). No patient with a positive PCU developed urinary sepsis. The main limitation of this study was the lack of pre-protocol control. CONCLUSIONS: We observed a clinically low and acceptable risk of UTI, with no incidence of sepsis, when FC was performed in asymptomatic patients with a PCU suggesting "infection". Routine cancellation of these patients is unnecessary and may worsen the burden on health service resources. PATIENT SUMMARY: We evaluated the safety of performing flexible cystoscopy when the urine dipstick on the day suggested presence of an "infection" but the patient had no symptoms of urinary tract infection (UTI). Our study in over 2000 patients demonstrated a low incidence of UTI, and none of these patients developed sepsis. We therefore recommend that flexible cystoscopy should not be cancelled automatically on the basis of the dipstick result alone, as it might delay a time-sensitive crucial diagnosis.
RESUMO
BACKGROUND AND IMPORTANCE: Palpitation is one of the commonest presenting complaints to the emergency department (ED). Diagnosis depends on capturing an ECG during the episode. Unlike syncope, patients retain consciousness and therefore their ability to activate an ECG event recorder. The Investigation of Palpitation in the ED study demonstrated Food and Drug Administration approved AliveCor/Kardia device that links to a smartphone app was safe and effective. A Smartphone Palpitation and Pre-syncope Ambulatory Care Clinic was therefore established. OBJECTIVES: To review the first year of patients attending the service to determine the number and cost-effectiveness of cardiac dysrhythmias diagnoses. DESIGN: Single-center cohort study. SETTINGS AND PARTICIPANTS: Royal Infirmary of Edinburgh, UK. All patients (over 16 years) presenting consecutively to ED with palpitation or pre-syncope, whose ECG was normal, had a compatible device and where an underlying cardiac dysrhythmia was possible were enrolled. INTERVENTION: Ambulatory Care Clinic utilizing the AliveCor/Kardia device. OUTCOME MEASURES AND ANALYSIS: Number diagnosed with cardiac dysrhythmia and mean cost per diagnosis. MAIN RESULTS: Between 24 July 2019 and 23 July 2020, 290 consecutive patients were referred of age 16-80 years (mean 43.3, SD 15.0). One hundred twenty (41.4%) were male. Two hundred thirty-seven (81.7%) were fitted with the device and 220 (75.9%) underwent full investigation. Seventeen of 237 (7.2%) patients had a cardiac diagnosis (12 atrial fibrillation/flutter, 5 supraventricular tachycardia and 1 atrial tachycardia). CONCLUSIONS: There were 17 cardiac diagnoses (7.2%). The cost per symptomatic rhythm diagnosis was 358 GBP (~415 Euro) and the cost per cardiac dysrhythmia diagnosis was 4570 GBP (~5298 Euro). A smartphone-based event recorder clinic should be considered for ED palpitation patients.

PURPOSE: Delays in achieving target mean arterial pressure (MAP) are associated with increased morbidity and mortality in patients with septic shock. This trial was conducted to test the hypothesis that early concomitant treatment with vasopressin and norepinephrine reduces the time to achieve and maintain target MAP compared with initial norepinephrine monotherapy. METHODS: A single-center prospective open-label trial was conducted in patients with septic shock between November 2015 and June 2016 at a medical intensive care unit in an academic medical center. Initial norepinephrine monotherapy was initiated between November 2015 and February 2016. Between March and June 2016, vasopressin was initiated within 4 hours of norepinephrine. The primary outcome was time to achieving and maintaining MAP of 65 mm Hg for at least 4 hours that was compared between groups using the Student t test and examined using the Kaplan-Meier curve (Clinical Trials registration: NCT02454348). RESULTS: Eighty-two patients were included (41 in each group). Patients treated with early concomitant vasopressin and norepinephrine more frequently had a positive culture (59% vs 37%, p=0.05) and grew nonlactose fermenting gram-negative bacilli (34% vs 10%, p=0.01) compared with patients treated with norepinephrine monotherapy, respectively. The median time to achieve and maintain MAP occurred faster in the early concomitant vasopressin and norepinephrine group, at 5.7 hours (interquartile range [IQR] 1.7-10.3 hrs), compared with 7.6 hours (IQR 3.6-16.7 hrs, p=0.058) in the norepinephrine group. Durations of therapy for norepinephrine or vasopressin, amount of norepinephrine received in the first 24 hours, norepinephrine dosage when MAP was achieved and maintained, maximum norepinephrine dosage, and mortality were similar between groups. CONCLUSION: Patients treated with early concomitant vasopressin and norepinephrine achieved and maintained MAP of 65 mm Hg faster than those receiving initial norepinephrine monotherapy, suggesting that overcoming vasopressin deficiency sooner may reduce the time patients spend in the early phase of septic shock.
