A Plain Language Summary of "Dostarlimab for primary advanced or recurrent endometrial cancer".

What is this summary about? Dostarlimab, also known by the brand name JEMPERLI, is a medicine that uses a patient's own immune system to treat endometrial cancer. Dostarlimab is a type of medicine called an immunotherapy. Immunotherapies help the immune system find and attack cancer cells. Dostarlimab stops cancer cells from being able to hide from the immune system, which allows the patient to have a boosted immune response against their cancer.The RUBY study is a phase 3 clinical study of primary advanced (cancer that has spread outside the uterus) or recurrent (cancer that has come back) endometrial cancer. A phase 3 clinical study looks at how well a new treatment works compared to the standard, or usual, treatment in a large patient population. The RUBY study is testing how well dostarlimab given with chemotherapy, followed by dostarlimab alone, works at delaying primary advanced or recurrent endometrial cancer from getting worse and preventing patients from dying, compared to chemotherapy given alone (the current standard treatment for primary advanced or recurrent endometrial cancer).What were the results? When dostarlimab was given with chemotherapy, this combination was found to delay primary advanced or recurrent endometrial cancer from getting worse and to prevent patients from dying, compared with chemotherapy given alone (without dostarlimab). Patients in the study who received dostarlimab with chemotherapy had a 36% lower risk of dying or having their cancer get worse.What do the results mean? The results from this study contributed to the approval of dostarlimab with chemotherapy as a new treatment option for patients with mismatch repair deficient/microsatellite instability-high primary advanced or recurrent endometrial cancer. As of the publication of this plain language summary of publication (PLSP), this combination of dostarlimab with chemotherapy has been approved in the United States of America, the United Kingdom, the European Union and Hong Kong.Clinical Trial Registration: NCT03981796 (RUBY).

Tumescent technique versus electrocautery mastectomy: A randomized controlled trial.

BACKGROUND: Breast cancer is the most common cancer in Danish women. In 2016 about 1450 (31%) Danish breast cancer patients had a mastectomy. The aim was to compare the frequency of postoperative complications in two methods of surgery, electrocautery dissection and tumescent technique, when performing a mastectomy. METHODS: Open randomized controlled trial of all consecutive primary breast cancer or DCIS female patients who underwent either a simple mastectomy or a modified radical mastectomy in Vejle Hospital, from January 2012 to October 2017. Primary outcomes were seroma production, bleeding, infection and necrosis. Secondary outcomes were duration of surgery and delay of adjuvant treatment caused by complications. Categorical outcome variables were compared between randomization groups using chi-square of Fisher exact test and continuous outcome variables by using Wilcoxon rank test. All analyses were performed at a 5% two-sided significance level. RESULTS: 357 patients met the inclusion criteria. 14 had bilateral mastectomy, i.e. 371 breasts. The two randomization groups consisted of 105 patients/107 breasts operated by tumescent technique and 98 patients/102 breasts operated by electrocautery technique. Tumescent technique produced more seroma though not significant (p = 0.631) (mean 605 vs. 630 ml). Bleeding in the tumescent group was 10.3% vs. 5.9% in the electrocautery group (p = 0.245). Infection (5.9% vs. 7.5% p = 0.645) and necrosis (4.9% vs. 4.7% p = 0.938) was uncommon with no difference between the intervention groups. Infection was most common cause of delay of adjuvant treatment; 3.9% in the electrocautery technique group. No significant difference in duration of surgery (p = 0.392). CONCLUSION: Both techniques are equally safe for simple and modified radical mastectomy.

Religious Values in Clinical Practice are Here to Stay.

Research to date has shown that health professionals often practice according to personal values, including values based on faith, and that these values impact medicine in multiple ways. While some influence of personal values are inevitable, awareness of values is important so as to sustain beneficial practice without conflicting with the values of the patient. Detecting when own personal values, whether based on a theistic or atheistic worldview, are at work, is a daily challenge in clinical practice. Simultaneously ethical guidelines of tone-setting medical associations like American Medical Association, the British General Medical Council and Australian Medical Association have been updated to encompass physicians' right to practice medicine in accord with deeply held beliefs. Framed by this context, we discuss the concept of value-neutrality and value-based medical practice of physicians from both a cultural and ethical perspective, and reach the conclusion that the concept of a completely value-neutral physician, free from influence of personal values and filtering out value-laden information when talking to patients, is simply an unrealistic ideal in light of existing evidence. Still we have no reason to suspect that personal values, whether religious, spiritual, atheistic or agnostic, should hinder physicians from delivering professional and patient-centered care.

A phase I study of the PARP inhibitor niraparib in combination with bevacizumab in platinum-sensitive epithelial ovarian cancer: NSGO AVANOVA1/ENGOT-OV24.

BACKGROUND: Combining poly(ADP-ribose) polymerase (PARP) inhibitors with antiangiogenic agents appeared to enhance activity vs PARP inhibitors alone in a randomized phase II trial. MATERIALS AND METHODS: In AVANOVA (NCT02354131) part 1, patients with measurable/evaluable high-grade serous/endometrioid platinum-sensitive ovarian cancer received bevacizumab 15 mg/kg every 21 days with escalating doses of niraparib capsules (100, 200, or 300 mg daily) in a 3 + 3 dose-escalation design. Primary objectives were to evaluate safety and tolerability and to determine the recommended phase II dose (RP2D). RESULTS: Three of 12 enrolled patients had germline BRCA2 mutations. In cycle 1, nine patients experienced grade 3 toxicities: five with hypertension, three with anemia, and one with thrombocytopenia. There was one dose-limiting toxicity (grade 4 thrombocytopenia with niraparib 300 mg), thus the RP2D was bevacizumab 15 mg/kg with niraparib 300 mg. The response rate was 50%; disease was stabilized in a further 42%. Median progression-free survival was 11.6 (95% confidence interval 8.4-20.1) months. Niraparib pharmacokinetics were consistent with historical single-agent data. Overlapping exposure was observed across the dose ranges tested on days 1 and 21. CONCLUSIONS: There was one dose-limiting toxicity; other adverse events were typical PARP inhibitor and antiangiogenic class effects. Niraparib-bevacizumab showed promising activity; Part 2 (vs bevacizumab) was recently reported and phase III comparison with standard-of-care therapy is planned.

The day of week of elective colorectal cancer surgery has no impact on mortality and morbidity.

INTRODUCTION: Recent studies have reported an asso-ciation between the day of week of surgery and post-operative mortality, meaning that patients undergoing surgery at the end of the week or during weekends may be at higher risk. The aim of this study was to investigate the influence of the day of week of surgery on mortality and morbidity rates in a national Danish cohort of patients undergoing major elective surgery for colorectal cancer. METHODS: In a register-based study design, all patients undergoing elective major surgery for colorectal cancer in Denmark during a ten-year period (2005-2014) were studied. Patients were identified in the National Colorectal Cancer Database. Any associations between short-time mortality and morbidity rates within 30 days after operation and the day of week of surgery, as well as patient characteristics, treatment data and socioeconomic data were analysed. RESULTS: We were unable to show that the day of week had a significant impact on short-term mortality or on surgical or medical complications. There was no evidence that patients undergoing surgery on Fridays had more risk factors or were more socioeconomically deprived than patients undergoing surgery from Monday to Thursday. CONCLUSIONS: The day of week of operation could not be shown to have any significant impact on the risk of post-operative surgical or medical complications or on short-term mortality in patients undergoing elective surgery for colorectal cancer in Denmark. FUNDING: none. TRIAL REGISTRATION: not relevant.

Predictive values of colorectal cancer alarm symptoms in the general population: a nationwide cohort study.

BACKGROUND: Alarm symptoms are used in many cancer referral guidelines. The objectives were to determine the 1-year predictive values (PVs) of colorectal cancer (CRC) alarm symptoms in the general population and to describe the proportion of alarm symptoms reported prior to diagnosis. METHODS: A nationwide prospective cohort of 69,060 individuals ≥40 years randomly selected from the Danish population was invited to complete a survey regarding symptoms and healthcare-seeking in 2012. Information on CRC diagnoses in a 12-month follow-up came from the Danish Cancer Registry. PVs and positive and negative likelihood ratios were calculated. RESULTS: A total of 37,455 individuals participated (response rate 54.2%). Sixty-four individuals were diagnosed with CRC. The single symptom with the highest positive PVs (PPV) and LR+ was rectal bleeding. PPVs were generally higher among individuals aged ≥75 years and highest among those reporting at least one specific alarm symptom that led to a GP contact. CONCLUSION: In general, the PPVs of CRC alarm symptoms are low and the NPVs high, especially in the youngest age groups. The LR + show a relative association with specific symptoms like rectal bleeding. Future campaigns on early diagnosis of CRC should focus on healthcare-seeking when experiencing rectal bleeding and target older people with the highest incidence.

Screening history and FIGO-stages among Danish women with cervical cancer in 2012-2014: a register-based study.

The objective was to examine whether attendance in the mass cervical screening programme has implications for the prognosis when cervical cancer is diagnosed. We performed a retrospective analysis of all cases of cervical cancer between 1st of January 2012 and 31st of December 2014 in the Region of Southern Denmark. The cases were retrieved from the Danish National Pathology Registry, PatoBank. Odds ratios (OR) with confidence intervals (95% CI) were calculated for attendees versus non-attendees of the screening programme by using χ2-test. 216 patients were included in the study. 61.6% of the study population had not attended the screening programme. Patients who had attended the programme were characterised by disease in low stage (OR = 3.14, 95% CI; 1.66 to 5.92), treatment with surgery alone (OR = 2.63, 95% CI; 1.49 to 4.64) and a lower risk of death (OR = 0.36, 95% CI; 0.15 to 0.87). Adenocarcinomas were more often detected among attendees of the programme compared to squamous cell carcinomas (OR = 4.06, 95% CI; 2.03 to 8.14). Statistically significant results regarding relapse of cancer (OR = 0.62, 95% CI; 0.23 to 1.68, p = 0.47) and lymph node metastases (OR = 0.62, 95% CI; 0.32 to 1.21, p = 0.19) were not found. Cervical cancer detected in women who had attended the mass cervical screening programme prior to the diagnosis, was shown to have a statistically significant lower FIGO stage (p = 0.0004) and was therefore linked to less extensive treatment options. Continued focus on increasing the participation rate of the programme is of importance, as the nonattendance rate continues to be high.

Second victims in the labor ward: Are Danish midwives and obstetricians getting the support they need?

OBJECTIVE: To describe midwives' and obstetricians' experiences on the level of support from colleagues and managers in Danish labor wards following adverse events. DESIGN, SETTING AND PARTICIPANTS: A 2012 National survey of Danish obstetricians and midwives was conducted to assess the level of support received in the workplace. MAIN OUTCOME MEASURES: Scales on social community at work, social support from colleagues and immediate superiors, and use of support mechanisms on labor wards after serious adverse events were assessed. RESULTS: 2098 midwives and obstetricians were invited to complete the survey (response rate 59%), and the analyses were carried out on the 593 respondents who had been involved in at least one traumatic childbirth at their current place of work. Respondents experienced high levels of social support from colleagues and social community at work, midwives significantly higher than obstetricians, and 95% of respondents had talked to colleagues about an adverse event. Respondents generally experienced low levels of social support and feedback from immediate superiors, and only 49% had talked to their immediate superior about an adverse event. Fifty% believed that the hospital had a clear process through which they could report adverse events, and 44% knew how to access the necessary confidential emotional support at work. CONCLUSIONS: Midwives and obstetricians experienced high levels of social support and feedback from colleagues who are the most frequent individuals to consult after adverse events. We strongly suggest developing second victim support programmes with a focus on offering peer support from qualified and trained peers.

The risk of fall accidents for home dwellers with dementia-A register- and population-based case-control study.

INTRODUCTION: Institutionalized people with dementia have an increased risk of fall accidents, but little is known about whether this increased risk holds for home dwellers. METHODS: This register- and population-based study comprised 115,584 cases and 394,679 controls. Cases were individuals with any fall between 2009 and 2014, and matched with up to six controls on age, sex, and geographic location. Individuals were excluded if they (1) had any fall in 2008, or (2) lived in a nursing home on the date of the fall. Dementia, other chronic diseases, and sedative medicines were assessed from Danish national registers. RESULTS: After adjusting for potential confounders, older people with dementia living at home had a 1.89-fold higher risk of fall (odds ratio = 1.89, 95% confidence interval [1.84-1.94], P < .001). DISCUSSION: Dementia almost doubles the risk of fall for older Danish people living at home. This highlights the need for effective fall preventions that target people with dementia.

Lifestyle, socioeconomic status and healthcare seeking among women with gynaecological cancer alarm symptoms: a combined questionnaire-based and register-based population study.

OBJECTIVES: To determine the proportion of contacts to general practitioner (GP) with recent onset gynaecological cancer alarm symptoms (pelvic pain, postmenopausal bleeding, bleeding during intercourse or pain during intercourse) and to analyse the associations between lifestyle factors, socioeconomic status and GP contact for these symptoms. DESIGN: Cross-sectional survey combined with data from national registers. SETTING: The general Danish population. PARTICIPANTS: A total of 25 866 non-pregnant women ≥20 years completed the survey. Women reporting at least one of four gynaecological alarm symptoms within the preceding 6 months form the study base (n=2957). RESULTS: The proportion of women reporting GP contact ranged from 21.1% (pain during intercourse) to 32.6% (postmenopausal bleeding). Women aged 60+ years had higher odds of reporting GP contact for at least one of the four gynaecological cancer alarm symptoms compared with those aged 20-39 years (OR 2.56, 95% CI 1.69 to 3.89), and immigrants had higher odds of reporting GP contact for at least one of the symptoms (OR 1.56, 95% CI 1.13 to 2.15) compared with ethnic Danish individuals. Among those reporting postmenopausal bleeding and/or bleeding during intercourse, women in the age group 60+ years had higher odds of reporting GP contact compared with those aged 20-39 years (OR 2.79, 95% CI 1.33 to 5.87). A high educational level (>12 years) was positively associated with reporting GP contact for postmenopausal bleeding and/or bleeding during intercourse compared with a low educational level (<10 years) (OR 2.23, 95% CI 1.19 to 4.19). No associations were found with lifestyle factors. CONCLUSIONS: Few women contacted their GP with recent onset gynaecological cancer alarm symptoms. Higher age, being immigrant and higher educational level increased the odds of GP contact. Future studies should explore the reasons for these findings as this may aid in prompting early diagnosis and thereby improve the prognosis of gynaecological cancer.

Predictive values of upper gastrointestinal cancer alarm symptoms in the general population: a nationwide cohort study.

BACKGROUND: Survival rates for upper gastrointestinal (GI) cancer are poor since many are diagnosed at advanced stages. Fast track endoscopy has been introduced to prompt diagnosis for patients with alarm symptoms that could be indicative of upper GI cancer. However, these symptoms may represent benign conditions and little is known about the predictive values of alarm symptoms of upper GI cancer in the general population. METHODS: The study is a nationwide cohort study of 60,562 individuals aged 45 years or above randomly selected from the Danish general population. Participants were invited to complete a survey comprising of questions on several symptom experiences, including alarm symptoms for upper GI cancer within the past four weeks. The participants were asked about specific symptoms (repeated vomiting, difficulty swallowing, signs of upper GI bleeding or persistent and recent-onset abdominal pain) and non-specific symptoms (nausea, weight loss, loss of appetite, feeling unwell and tiredness). We obtained information on upper GI cancer diagnosed in a 12-month period after completing the questionnaire from the Danish Cancer Registry. We calculated positive predictive values and positive likelihood ratios for the association between alarm symptom and subsequent upper GI cancer. RESULTS: A total of 33,040 individuals above 45 years completed the questionnaire, yielding a response rate of 54.6%. Respondents were fairly respresentative of the study sample. During the follow-up period, 18 people were diagnosed with upper GI cancer. The number of incident cancers was similar among eligible non-respondents. Two thirds of the respondents with an upper GI malignancy had experienced one or more alarm symptoms. The positive predictive value for being diagnosed with upper GI cancer after reporting a least one alarm symptom was 0.1% (95% CI:0.0-0.1%). The positive likelihood ratio was 4.4 for specific alarm symptoms and 1.1 for non-specific alarm symptoms. CONCLUSIONS: We found that positive predictive values of alarm symptoms of upper GI cancer experienced in the general population are low. It is important knowledge that despite denoted alarm symptoms even patients with specific alarm symptoms of upper GI cancer have a low risk of being diagnosed with upper GI cancer.

Impact of socioeconomic position and distance on mental health care utilization: a nationwide Danish follow-up study.

PURPOSE: To determine the impact of socioeconomic position (SEP) and distance to provider on outpatient mental health care utilization among incident users of antidepressants. METHOD: A nationwide register-based cohort study of 50,374 person-years. RESULTS: Persons in low SEP were more likely to have outpatient psychiatrist contacts [odds ratio (OR) 1.25; confidence interval (CI) 1.17-1.34], but less likely to consult a co-payed psychologist (OR 0.49; CI 0.46-0.53) and to get mental health service from a GP (MHS-GP) (OR 0.81; CI 0.77-0.86) compared to persons in high SEP after adjusting for socio-demographics, comorbidity and car ownership. Furthermore, persons in low SEP who had contact to any of these therapists tended to have lower rates of visits compared to those in high SEP. When distance to services increased by 5 km, the rate of visits to outpatient psychiatrist tended to decrease by 5% in the lowest income group (IRR 0.95; CI 0.94-0.95) and 1% in the highest (IRR 0.99; CI 0.99-1.00). Likewise, contact to psychologists decreased by 11% in the lowest income group (IRR 0.89; CI 0.85-0.94), whereas rate of visits did not interact. CONCLUSION: Patients in low SEP have relatively lower utilization of mental health services even when services are free at delivery; co-payment and distance to provider aggravate the disparities in utilization between patients in high SEP and patients in low SEP.

What triggers healthcare-seeking behaviour when experiencing a symptom? Results from a population-based survey.

BACKGROUND: The decision process of whether or not to contact the GP is influenced by different factors which have not all been well examined. AIM: The aim of this study was to analyse whether contact to the GP is associated with concern about the symptom, influence on daily activities and symptom burden, such as the total number of symptoms experienced by each person in a general population. DESIGN & SETTING: This Danish nationwide cross-sectional study comprises a random sample of 100 000 people, representative of the adult Danish population ≥20 years. METHOD: Baseline data were collected in a web-based survey conducted from June to December 2012. RESULTS: In total 49 706 (52.5%) individuals answered the questionnaire; 45 483 (91.5%) individuals experienced at least one of 44 predefined symptoms during the 4 weeks preceding the completion of the questionnaire. They reported 268 772 symptom experiences of which 58 370 symptoms (21.7%) resulted in contact with a GP. A high level of concern and influence on daily activities was associated with significantly higher odds for GP contact. A high burden of symptoms was associated with lower odds of contact with the GP. CONCLUSION: Approximately every fifth symptom reported by individuals from the general population leads to GP contact. Influence on daily activities, burden of symptoms, and concern about the symptom were significant factors associated with the decision of whether to contact the GP. No overall association between sex and GP contact was observed.

Identification of Associations Between Prescribed Medications and Cancer: A Nationwide Screening Study.

PURPOSE: We present a systematic screening for identifying associations between prescribed drugs and cancer risk using the high quality Danish nationwide health registries. METHODS: We identified all patients (cases) with incident cancer in Denmark during 2000-2012 (n=278,485) and matched each case to 10 controls. Complete prescription histories since 1995 were extracted. Applying a two-phased case-control approach, we first identified drug classes or single drugs associated with an increased or decreased risk of 99 different cancer types, and further evaluated potential associations by examining specificity and dose-response patterns. FINDINGS: 22,125 drug-cancer pairs underwent evaluation in the first phase. Of 4561 initial signals (i.e., drug-cancer associations), 3541 (78%) failed to meet requirements for dose-response patterns and specificity, leaving 1020 eligible signals. Of these, 510 signals involved the use of single drugs, and 33% (166 signals) and 67% (344 signals) suggested a reduced or an increased cancer risk, respectively. While a large proportion of the signals were attributable to the underlying conditions being treated, our algorithm successfully identified well-established associations, as well as several new signals that deserve further investigation. CONCLUSION: Our results provide the basis for future targeted studies of single associations to capture novel carcinogenic or chemopreventive effects of prescription drugs.

Association between sexually transmitted disease and church membership. A retrospective cohort study of two Danish religious minorities.

OBJECTIVES: Studies comprising Danish Seventh-day Adventists (SDAs) and Danish Baptists found that members have a lower risk of chronic diseases including cancer. Explanations have pointed to differences in lifestyle, but detailed aetiology has only been sparsely examined. Our objective was to investigate the incidence of sexually transmitted diseases (STDs) among Danish SDAs and Baptists as a proxy for cancers related to sexual behaviour. METHODS: We followed the Danish Cohort of Religious Societies from 1977 to 2009, and linked it with national registers of all inpatient and outpatient care contacts using the National Patient Register. We compared the incidence of syphilis, gonorrhoea and chlamydia among members of the cohort with the general population. RESULTS: The cohort comprised 3119 SDA females, 1856 SDA males, 2056 Baptist females and 1467 Baptist males. For the entire cohort, we expected a total of 32.4 events of STD, and observed only 9. Female SDAs and Baptists aged 20-39 years had significant lower incidence of chlamydia (both p<0.001). Male SDAs and Baptists aged 20-39 years also had significant lower incidence of chlamydia (p<0.01 and p<0.05, respectively). No SDA members were diagnosed with gonorrhoea, when 3.4 events were expected, which, according to Hanley's 'rule of three', is a significant difference. No SDA or Baptist was diagnosed with syphilis. CONCLUSIONS: The cohort shows significant lower incidence of STD, most likely including human papillomavirus, which may partly explain the lower incidence of cancers of the cervix, rectum, anus, head and neck.

Early intervention for childhood overweight: A randomized trial in general practice.

OBJECTIVE: To evaluate the effect of two intervention modalities concerning overweight and obesity among children in general practice. DESIGN: Prospective randomized controlled trial. SETTING: A total of 60 general practices in the former County of Funen, Denmark. SUBJECTS: Overweight children, identified by International Obesity Task Force criteria, aged 5-9 years. INTERVENTION: Model 1 with health consultations in general practice during a two-year period or Model 2, an educational programme for the children and their families in addition to the health consultations. MAIN OUTCOME MEASURES: Change in body mass index (BMI) z-score in order to compare the results, independent of gender- and age-related changes over time. RESULTS: A total of 80 children were recruited with 35 and 45 children allocated to Model 1 and Model 2, respectively. No significant differences were found in the change in BMI z-score (SDS) between the two groups. A decrease in the mean BMI z-score from baseline to study end of -0.20 (95%CI -0.38 to -0.01) in Model 1 and -0.26 (95%CI -0.44 to -0.09) in Model 2, respectively, was detected. The majority of the participants (2/3) continued in the study for more than one year in both models, with a mean of 12 consultations in general practice. CONCLUSION: In this particular setting the two intervention strategies against overweight and obesity did not differ significantly with regard to change in BMI z-scores.

Point-of-care ultrasonography in patients admitted with respiratory symptoms: a single-blind, randomised controlled trial.

BACKGROUND: When used with standard diagnostic testing, point-of-care ultrasonography might improve the proportion of patients admitted with respiratory symptoms who are correctly diagnosed 4 h after admission to the emergency department. We therefore assessed point-of-care ultrasonography of the heart, lungs, and deep veins in addition to the usual initial diagnostic testing in this patient population. METHODS: In a prospective, parallel-group trial in the emergency department at Odense University Hospital, Odense, Denmark, patients (≥18 years) with a respiratory rate of more than 20 per min, oxygen saturation of less than 95%, oxygen therapy, dyspnoea, cough, or chest pain were randomly assigned in a 1:1 ratio with a computer-generated list to a standard diagnostic strategy (control group) or to standard diagnostic tests supplemented with point-of-care ultrasonography of the heart, lungs, and deep veins (point-of-care ultrasonography group). The primary endpoint was the percentage of patients with a correct presumptive diagnosis 4 h after admission to the emergency department. Only the physicians doing the primary clinical assessment and the auditors were masked. Analyses were by intention to treat. The study is registered with ClinicalTrials.gov, number NCT01486394. FINDINGS: Between Dec 7, 2011, and March 15, 2013, 320 patients were randomly assigned to the control group (n=160) and point-of-care ultrasonography group (n=160). 158 patients in the point-of-care ultrasonography group and 157 in the control group were analysed. 4 h after admission to the emergency department, 139 patients (88·0%; 95% CI 82·8-93·1) in the point-of-care ultrasonography group versus 100 (63·7%; 56·1-71·3) in the control group had correct presumptive diagnoses (p<0·0001). The absolute and relative effects were 24·3% (95% CI 15·0-33·1) and 1·38 (1·01-1·31), respectively. No adverse events were reported. INTERPRETATION: Point-of-care ultrasonography is a feasible, radiation free, diagnostic test, which alongside standard diagnostic tests is superior to standard diagnostic tests alone for establishing a correct diagnosis within 4 h. It should therefore be considered for routine use as part of the standard diagnostic tests in the emergency department for patients admitted with respiratory symptoms.
