Management of hypertensive emergencies and urgencies: narrative review.

Hypertensive emergencies are distinguished from hypertensive urgencies by the presence of clinical or laboratory target organ damage. The most common forms of target organ damage in developed countries are pulmonary oedema/heart failure, acute coronary syndrome, ischaemic and haemorrhagic stroke. In the absence of randomised trials, it is inevitable that guideline writers differ slightly regarding the speed and extent to which blood pressure should be lowered acutely. An appreciation of cerebral autoregulation is key and should underpin treatment decisions. Hypertensive emergencies, with the notable exception of uncomplicated malignant hypertension, require intravenous antihypertensive medication which is most safely given in high dependency or intensive care settings. Patients with hypertensive urgency are often treated with medications that lower their blood pressure acutely, although there is no evidence to support this practice. This article aims to review current guidelines and recommendations, and to provide user friendly management strategies for the general physician.

Design and implementation of two medical escape rooms: An educational case study.

BACKGROUND: Escape rooms (ERs) have become increasingly popular as an interactive educational experience, especially in medical education. We present an educational case study covering the design, implementation and evaluation of two medical ERs. APPROACH: We created ERs for senior medical students from Glasgow University on rotation at Dumfries and Galloway Royal Infirmary. Students assessed and managed a patient presenting with either stroke or sepsis. The information gained during students' assessment 'unlocked' padlocks or generated codes providing further information or equipment. The ERs were evaluated following analysis of video recordings, debriefings and student and faculty feedback. EVALUATION: Evaluation was focused on students' perceptions of the teaching experience, with changes made to the scenario design following student feedback and faculty reflection. Feedback was positive; students enjoyed the 'fun' nature of the learning experience. They felt they gained knowledge covering the subject areas and that the ERs also highlighted the importance of non-technical skills. We discuss the aspects of ER design and implementation that we learnt during the evaluation process. IMPLICATIONS: We have shown that medical ERs provide an immersive and engaging learning experience for students. We recognise a need for a more objective review of knowledge gained. We hope that by sharing our design and assessment of two medical ERs, we may inform and inspire other educators to consider ERs as an innovative learning experience.

Unexplained chest pain in a patient with giant cell arteritis? Think aortic dissection.

Giant cell arteritis (GCA) is the commonest of the large-vessel vasculitides. Aortic inflammation in patients with GCA was first described over 80 years ago, but it has only been possible to study this systematically following the development of more sophisticated imaging techniques such as computed tomography angiography, magnetic resonance angiography and positron emission tomography. Both NICE and the European League Against Rheumatism (EULAR) recognise that aortic dissection may complicate GCA but stop short of recommending routine imaging. We report a case that highlights a possible need for large-vessel imaging at the time of diagnosis and during follow-up to enable earlier recognition of aortitis and associated complications including dissection.

Improving the annual monitoring rates of testosterone replacement therapy patients in primary care.

INTRODUCTION: Testosterone replacement therapy (TRT) is the treatment of choice for male hypogonadism. British Society for Sexual Medicine (BSSM) guidelines on adult testosterone deficiency recommend that TRT patients undergo annual monitoring of their testosterone levels and potential complications of treatment; though evidence suggests that substantial numbers of men on TRT are not monitored adequately. METHODS: Review of the electronic patient record from a single general practice in southwest Scotland revealed that only 1 of 26 (4%) TRT patients had been monitored as per BSSM guidelines in the previous 12 months. Additionally, when monitoring was undertaken there was inconsistency in the blood tests requested. The use of quality improvement (QI) tools including process mapping and cause-and-effect diagram identified staff and patient knowledge of monitoring requirements and the lack of an effective recall system as areas for improvement. We tested three change ideas: the utilisation of an existing recall system for long-term therapies; a TRT Ordercomms blood group template (OBGT) to standardise monitoring; and a patient information leaflet (PIL) to improve patient education. The aim of this project was to achieve 60% annual monitoring rate. RESULTS: The percentage of patients monitored for testosterone levels and potential TRT complications increased from 4% (1/26) to 65% (17/26) over a 7-week test period. The utilisation of the existing recall system was a particularly effective intervention, leading to an increase from 4% (1/26) to 31% (8/26) in the first 2 weeks. CONCLUSION: The use of QI tools was associated with over 60% of male TRT patients receiving comprehensive annual monitoring, as per BSSM guidelines. Our findings support the hypothesis that a patient recall system, combined with an OBGT and a PIL led to this increase.

Teledermatology to reduce face-to-face appointments in general practice during the COVID-19 pandemic: a quality improvement project.

Teledermatology is an important subspecialty of telemedicine that continues to evolve with advances in telecommunication and mobile phone technology. A 19-week primary care quality improvement project collected baseline data and tested three change ideas, using the Model for Improvement method, with primary and secondary aims: to increase the weekly percentage of remote dermatological consultations with supporting images that were successfully concluded remotely to greater than 80% and to reduce the weekly percentage of dermatological face-to-face consultations to less than 50%. We hypothesised that by improving the quality of patient images and the confidence of reception staff in triaging skin complaints, there would be a decrease in the weekly number of face-to-face dermatological appointments, thereby decreasing the risk of COVID-19 transmission within the practice and community. Two change ideas focused on supporting patients to improve image quality by introducing '4 Key Instructions' and a patient information leaflet (PIL). The third focused on increasing reception staff confidence in triaging skin complaints by introducing a triage pathway guidance tool. A total of 253 dermatological consultations were analysed: 170 of these were telephone consultations with 308 supporting images. Process measures showed clear improvements in the quality of images provided by patients which likely contributed to an increase in completed remote consultation. Our primary outcome measure was achieved. Our secondary outcome measure suggested that in the absence of high-quality images, it might not be possible to reduce dermatological face-to-face consultations much below 50% in primary care. Process measures showed clear improvements in the quality of images provided by patients which likely contributed to the increase in remote consultation. The implications of these findings for the theory of change are discussed.

Do we overtreat patients with presumed neutropenic sepsis?

PURPOSE: Many aspects of the management of neutropenic sepsis remain controversial. These include the choice of empiric antibiotic, the duration of antibiotic therapy and the possibility that very low-risk cases may be managed safely with oral rather than intravenous therapy. STUDY DESIGN: Retrospective cohort study conducted in a district general hospital serving a population of 148 000 in south west Scotland. RESULTS: Fifty one patients with cancer, whose neutrophil count was less than 1.0×109/L within 21 days of their last chemotherapy, were admitted as a medical emergency in 2019. All received antibiotic because of presumed neutropenic sepsis. A total of 4 patients had positive blood cultures (group 1), 12 patients had a clinical focus of infection but no clear pathogen (group 2), while 35 patients had neither (group 3). Group 3 patients were more likely to have a solid tumour, less likely to be febrile, had shorter time to neutrophil recovery and higher Multinational Association of Supportive Care in Cancer scores, though not all of these comparisons achieved statistical significance. Median intravenous plus oral antibiotic duration in group 3 patients was 9 days with median hospital stay of 7 days, raising the possibility of overtreatment. Retrospectively, 23 (66%) group 3 patients had MASSC Risk Index greater than 21 suggesting they were at low risk of complications. CONCLUSIONS: It seems likely that many low-risk neutropenic cancer patients with solid tumours could be managed as effectively and as safely with shorter courses of antibiotic, with oral rather than intravenous antibiotic, as outpatients rather than inpatients and with an overall positive impact on antimicrobial stewardship.

Regional variation in COVID-19 positive hospitalisation across Scotland during the first wave of the pandemic and its relation to population density: A cross-sectional observation study.

BACKGROUND: There have been large regional differences in COVID-19 virus activity across the UK with many commentators suggesting that these are related to age, ethnicity and social class. There has also been a focus on cases, hospitalisations and deaths rather than on hospitalisation rates expressed per 100,000 population. The purpose of our study was to examine regional variation in COVID-19 positive hospitalisation rates in Scotland during the first wave of the pandemic and the possibility that these might be related to population density. METHODS AND FINDINGS: This was a repeated point prevalence study. The number of COVID-19 positive patients hospitalised in the eleven Scottish mainland health boards peaked at 1517 on 19th April, then fell to a low of 243 on 16th August before rising slightly to 262 on 15th September. In July, August and September only four boards had more than 5 hospitalised patients. There was a statistically significant relationship between hospitalisation rates and population density on 97.7% of individual days during the first wave of the pandemic (Pearson's r 0.62-0.93, with 123 of a possible 174 days having p values <0.001). Multiple linear regression analyses performed on data from the 11 mainland boards across six time points suggest that population density accounted for 70.2% of the variation in hospitalisation rate in April, 72.3% in May, 81.2% in June, 91.0% in July, 91.0% in August, and 88.1% in September. Neither population median age nor median social deprivation score at health board level were statistically significant in the final model for hospitalisation. CONCLUSION: There were large differences in crude COVID-19 hospitalisation rates across the 11 mainland Scottish health boards, that were significantly related to population density. Given that lockdown was originally introduced to prevent the NHS from being overwhelmed, we believe our results support a regional rather than a national approach to lifting or reimposing more restrictive measures, and that hospitalisation rates should be part of the decision making process.

Patients with markedly elevated D-dimer who do not have pulmonary embolism.

OBJECTIVE: To determine the cause of a markedly raised D-dimer among patients in whom a diagnosis of pulmonary embolism (PE) has been excluded by CT pulmonary angiogram (CTPA) with particular reference to new cases of cancer and aortic dissection. METHODS: One thousand consecutive patients, suspected of PE, who had undergone CTPA and for whom a D-dimer had been requested, were seen between 2012 and 2016. Retrospectively we examined the case records of all those in the top quintile of the D-dimer distribution whose CTPA was negative for PE. D-dimer in the top quintile ranged from 7.5 to 260 times upper limit normal. RESULTS: Eighty-five patients fulfilled our inclusion criteria. The likely causes of their very high D-dimer were infection (n=35, 41.2%), cardiovascular disease (n=12, 14.1% including two patients with previously undiagnosed aortic dissection), surgery or trauma (n=12, 14.1%), new or active cancer (n=9, 10.6% comprising six new cancers and three patients with cancers diagnosed previously that were considered to be active) and miscellaneous causes (n=17, 20.0%). Thirty-five patients (43.5%) died over a 2-year follow-up. Kaplan-Meier survival analysis showed poorer outcomes for patients with new or active cancer, when compared with those with no known cancer (p<0.001). CONCLUSIONS: We have shown that a small proportion of patients suspected of PE whose D-dimers are markedly elevated have diagnoses we would not want to miss including previously unsuspected cancer and aortic dissection. Further studies will be required to define the optimal workup of patients with extremely high D-dimer who do not have venous thromboembolism.

Syncope in pulmonary embolism: a retrospective cohort study.

OBJECTIVE: To determine the prevalence of syncope or collapse in pulmonary embolism (PE). METHODS: A retrospective cohort study was conducted. We examined the frequency with which syncope or collapse (presyncope) occurred alone or with other symptoms and signs in an unselected series of 224 patients presenting to a district general hospital with PE between September 2012 and March 2016. Confirmation of PE was by CT pulmonary angiogram in each case. RESULTS: Our cohort of 224 patients comprised 97 men and 127 women, average age 66 years with age range of 21-94 years. Syncope or collapse was one of several symptoms and signs that led to a diagnosis of PE in 22 patients (9.8%) but was never the sole presenting feature. In descending order, these other clinical features were hypoxaemia (17 patients), dyspnoea (12), chest pain (9), tachycardia (7) and tachypnoea (7). ECG abnormalities reported to occur more commonly in PE were found in 13/17 patients for whom ECGs were available. Patients with PE presenting with syncope or collapse were judged to have a large clot load in 15/22 (68%) cases. CONCLUSION: Syncope was a frequent presenting symptom in our study of 224 consecutive patients with PE but was never the sole clinical feature. It would be difficult to justify routine testing for PE in patients presenting only with syncope or collapse.

Time to revisit the skills and competencies required to work in rural general hospitals.

OBJECTIVES: To determine the structure and demographic of medical teams working in Rural General Hospitals (RGHs) in Scotland, and to gain insight into their experiences and determine their opinions on a remote and rural medical training pathway. DESIGN: Structured face-to-face interviews. Interviews were partially anonymised, and underwent thematic analysis. SETTING: Medical departments of the six RGHs in Scotland 2018-2019. PARTICIPANTS: 14 medical consultants and 23 junior doctors working in RGHs in Scotland. Inclusion criteria: Present at time of site visit, medical consultant in an RGH or junior doctor working in an RGH who provides care for medical patients. Exclusion criteria: Doctors on leave or off shift. Medical consultants with less than one month of experience in post. Non-medical specialty consultants e.g. surgical or anaesthetic consultants. RESULTS: Of 21 consultant posts in the RGHs, only eight are filled with resident consultants, the remainder rely on locums. Consultants found working as generalists rewarding and challenging, and juniors found it to be a good training experience. Consultants feel little professional isolation due to modern connectivity. The majority of consultants (12/14) and all junior doctors favour a remote and rural medicine training pathway encompassing a mandatory paediatrics component, and feel this would help with consultant recruitment and retention. CONCLUSION: RGHs medical departments are reliant on locum consultants. The development of a remote and rural training medical training pathway is endorsed by the current medical teams of RGHs and has the potential to improve medical consultant staffing in RGHs.

Electrocardiographic recognition of life-threatening hyperkalaemia: the hyperkalaemic Brugada sign.

Consider life-threatening hyperkalaemia if the ECG shows high take-off with coved ST segment elevation and negative T wave in lead V1 superimposed on other ECG signs of hyperkalaemia and treat with calcium gluconate while waiting for blood chemistry results.

Cannabis hyperemesis syndrome: still under recognised after all these years.

Cannabis hyperemesis syndrome (CHS) is characterised by cyclical vomiting, relieved by hot water bathing, in the context of chronic cannabis consumption. Many cannabis users find this hard to accept given that cannabis is often promoted as a treatment for vomiting. Stopping cannabis is the best and only effective way to manage the condition. We report a case showing that CHS remains under recognised 15 years after it was first described.

ECG in suspected pulmonary embolism.

OBJECTIVE: To establish the diagnostic value of prespecified ECG changes in suspected pulmonary embolism (PE). METHODS: Retrospective case-control study in a district general hospital setting. We identified 189 consecutive patients with suspected PE whose CT pulmonary angiogram (CTPA) was positive for a first PE and for whom an ECG taken at the time of presentation was available. We matched these for age±3 years with 189 controls with suspected PE whose CTPA was negative. We considered those with large (n=76) and small (n=113) clot load separately. We scored each ECG for the presence or absence of eight features that have been reported to occur more commonly in PE. RESULTS: 20%-25% of patients with PE, including those with large clot load, had normal ECGs. The most common ECG abnormality in patients with PE was sinus tachycardia (28%). S1Q3T3 (3.7%), P pulmonale (0.5%) and right axis deviation (4.2%) were infrequent findings. Right bundle branch block (9.0%), atrial dysrhythmias (10.1%) and clockwise rotation (20.1%) occurred more frequently but were also common in controls. Right ventricular (RV) strain pattern was significantly more commonly in patients than controls, 11.1% vs 2.6% (sensitivity 11.1%, specificity 97.4%; OR 4.58, 95% CI 1.63 to 15.91; p=0.002), particularly in those with large clot load, 17.1% vs 2.6% (sensitivity 17.1%, specificity 97.4%; OR 7.55, 95% CI 1.62 to 71.58; p=0.005). CONCLUSION: An ECG showing RV strain in a breathless patient is highly suggestive of PE. Many of the other ECG changes that have been described in PE occur too infrequently to be of predictive value.

Death within 1 year among emergency medical admissions to Scottish hospitals: incident cohort study.

BACKGROUND: It is increasingly recognised that large numbers of hospital inpatients have entered the last year of their lives. AIM: To establish the likelihood of death within 12 months of admission to hospital; to examine the influence on survival of a cancer diagnosis made within the previous 5 years; to assess whether previous emergency admissions influenced mortality; and to compare mortality with that of the wider Scottish population. DESIGN: Incident cohort study. SETTING: 22 hospitals in Scotland. PARTICIPANTS: This study used routinely collected data from 10 477 inpatients admitted as an emergency to medicine in 22 Scottish hospitals between 18 and 31 March 2015. These data were linked to national death records and the Scottish Cancer Registry. PRIMARY OUTCOME MEASURES: 1 year cohort mortality compared with that of the general Scottish population. Patient factors correlating with higher risk of mortality were identified using Cox regression. RESULTS: There were 2346 (22.4%) deaths in the year following the census admission. Six hundred and ten patients died during that admission (5.8% of all admissions and 26% of all deaths) while 1736 died after the census admission (74% of all deaths). Malignant neoplasms (33.8%), circulatory diseases (22.5%) and respiratory disease (17.9%) accounted for almost three-quarters of all deaths. Mortality rose steeply with age and was five times higher at 1 year for patients aged 85 years and over compared with those who were under 60 years of age (41.9%vs7.9%) (p<0.001). Patients with cancer had a higher mortality rate than patients without a cancer diagnosis (55.6%vs16.6%) (p<0.001). Mortality was higher among patients with one or more emergency medical admissions in the previous year (30.1% v 15.1%) (p<0.001). Age/sex-standardised mortality was 110.4 (95% CI 104.4 to 116.5) for the cohort and 11.7 (95% CI 11.6 to 11.8) for the Scottish population, a 9.4-fold increase in risk. CONCLUSION: These data may help identify groups of patients admitted to hospital as medical emergencies who are at greatest risk of dying not only during admission but also in the following 12 months.
