User perceptions of COVID-19 telemedicine testing services, disease risk, and pandemic preparedness: findings from a private clinic in Hong Kong.

INTRODUCTION: During the coronavirus disease 2019 (COVID-19) pandemic, telemedicine has been regarded as a method for providing safe access to healthcare. Here, we explored the experiences of individuals using telemedicine in Hong Kong during the COVID-19 pandemic to understand their risk perceptions and preparedness measures. METHODS: We conducted a cross-sectional online survey of telemedicine users of private clinic-based COVID-19 testing services from 6 April to 11 May 2020. All users were invited to complete an anonymous online survey regarding COVID-19 risk perception and preparedness measures. The results of the survey were compared with the findings of a previous territory-wide survey. RESULTS: In total, 141 of 187 telemedicine users agreed to participate; the response rate was 75.4%. Of the participants, 95.1% (116/122) believed that telemedicine consultations were useful. Nearly half of the participants (49.0%) agreed or strongly agreed that telemedicine consultations were appropriate during the COVID-19 pandemic. Most participants believed that telemedicine consultations could perform the functions of 'health protection, promotion and disease prevention' (73.6%) and 'diagnosis' (64.0%). Concerning the choice of telemedicine provider, almost all participants (99.2%) were willing to consult medical doctors; more than half of the participants (54.1%) were willing to consult registered nurses, but only 13.1% were willing to consult non-clinical staff who had been trained to provide telemedicine services. CONCLUSION: The use of telemedicine for screening and patient education can be encouraged during the COVID-19 pandemic in Hong Kong.

Managing loneliness: a qualitative study of older people's views.

Engaging with older people who self-identify as lonely may help professionals in mental health and other services understand how they deal with loneliness. The evidence-base for effective interventions to address loneliness is inconclusive. This study aimed to explore how community-dwelling lonely older people in England manage their experiences of loneliness. Twenty eight community-dwelling older people identifying as lonely, based on responses to two loneliness measures (self-report and a standardised instrument), participated in in-depth interviews between 2013 and 2014. Fifteen lived alone. Thematic analysis of transcribed interviews was conducted by a multidisciplinary team including older people.Participants drew on a range of strategies to ameliorate their distress which had been developed over their lives and shaped according to individual coping styles and contexts. Strategies included physical engagement with the world beyond their home, using technologies, planning, and engagement with purpose in an 'outside world', and acceptance, endurance, revealing and hiding, positive attitude and motivation, and distraction within an 'inside world'. Strategies of interests and hobbies, comparative thinking, religion and spirituality and use of alcohol straddled both the inside and outside worlds. Participants conveyed a personal responsibility for managing feelings of loneliness rather than relying on others. This study includes the experiences of those living with loneliness whilst also living with other people. When developing policy and practice responses to loneliness it is important to listen attentively to the views of those who may not be engaging with services designed for 'the lonely' and to consider their own strategies for managing it.

Evaluation of systemic vasoconstriction and prognosis using thermography: a systematic review.

PURPOSE: This systematic review investigates whether infrared thermography (IRT) can measure systemic vasoconstriction and addresses the value of IRT in assessing circulatory deficiency and prognoses. METHODS: Design was based on the PRISMA criteria and a systematic search of 6 databases was performed. RESULTS: Of 3,198 records, five articles were included. Three clinical studies were identified; two found significant correlations between IRT obtained temperatures and mortality. An experimental study found an association between peripheral temperature and stroke volume. An animal study found that central-peripheral temperature differences correlated with shock index, mean arterial pressure, and disease progression. CONCLUSIONS: Data from the most valid study suggests that central-peripheral temperature differences should be investigated further, both on its own, and integrated with other variables.

Thermographic visualization of facial vasoconstriction is associated with 30-day all-cause mortality in medical patients; prospective observational two-site cohort study.

INTRODUCTION: Quick and reliable assessment of acute patients is required for accurate triage. The temperature gradient between core and peripheral temperature could possibly instantly provide information on circulatory status. METHODS: Adult medical patients, who did not receive supplementary oxygen, attending two emergency departments, had a thermographic image taken on arrival. The association between 30-day mortality and gradients was tested using logistic regression. RESULTS: 726 patients were studied, median age was 64 years and 14 (1.9%) died within 30 days. There was a significant association between mortality and temperature gradient, comparable to vital signs, age, and clinical intuition. CONCLUSION: Temperature gradient between nose and eye had an acceptable discriminatory power for 30-day all-cause mortality.

Assessing the severity of Type 2 diabetes using clinical data-based measures: a systematic review.

AIMS: To identify and critically appraise measures that use clinical data to grade the severity of Type 2 diabetes. METHODS: We searched MEDLINE, Embase and PubMed between inception and June 2018. Studies reporting on clinical data-based diabetes-specific severity measures in adults with Type 2 diabetes were included. We excluded studies conducted solely in participants with other types of diabetes. After independent screening, the characteristics of the eligible measures including design and severity domains, the clinical utility of developed measures, and the relationship between severity levels and health-related outcomes were assessed. RESULTS: We identified 6798 studies, of which 17 studies reporting 18 different severity measures (32 314 participants in 17 countries) were included: a diabetes severity index (eight studies, 44%); severity categories (seven studies, 39%); complication count (two studies, 11%); and a severity checklist (one study, 6%). Nearly 89% of the measures included diabetes-related complications and/or glycaemic control indicators. Two of the severity measures were validated in a separate study population. More severe diabetes was associated with increased healthcare costs, poorer cognitive function and significantly greater risks of hospitalization and mortality. The identified measures differed greatly in terms of the included domains. One study reported on the use of a severity measure prospectively. CONCLUSIONS: Health records are suitable for assessment of diabetes severity; however, the clinical uptake of existing measures is limited. The need to advance this research area is fundamental as higher levels of diabetes severity are associated with greater risks of adverse outcomes. Diabetes severity assessment could help identify people requiring targeted and intensive therapies and provide a major benchmark for efficient healthcare services.

Cross-sectional study on emergency department management of sepsis.

INTRODUCTION: Emergency departments (EDs) play an important role in the early identification and management of sepsis. Little is known about local EDs' processes of care for sepsis, adoption of international recommendations, and the impact of the new Sepsis-3 definitions. METHODS: Structured telephone interviews based on the United Kingdom Sepsis Trust 'Exemplar Standards for the Emergency Management of Sepsis' were conducted from January to August 2017 with nominated representatives of all responding public hospital EDs in Hong Kong, followed by a review of hospital/departmental sepsis guidelines by the investigators. RESULTS: Sixteen of the 18 public EDs in Hong Kong participated in the study. Among various time-critical medical emergencies such as major trauma, sepsis was perceived by the interviewees to be the leading cause of in-hospital mortality and the second most important preventable cause of death. However, only seven EDs reported having departmental guidelines on sepsis care, with four adopting the Quick Sequential Organ Failure Assessment score or its modified versions. All responding EDs reported that antibiotics were stocked within their departments, and all EDs with sepsis guidelines mandated early intravenous antibiotic administration within 1 to 2 hours of detection. Reported major barriers to optimal sepsis care included lack of knowledge and experience, nursing human resources shortages, and difficulty identifying patients with sepsis in the ED setting. CONCLUSION: There are considerable variations in sepsis care among EDs in Hong Kong. More training, resources, and research efforts should be directed to early ED sepsis care, to improve patient outcomes.

Painful sex (dyspareunia) in women: prevalence and associated factors in a British population probability survey.

OBJECTIVE: To estimate the prevalence of painful sex among women in Britain, and to explore associated sexual, relationship and health factors that should be considered in assessment. DESIGN: Multi-stage, clustered and stratified population probability sample survey, using computer-assisted self-interview. Sample frame was the British Postcode Address File. SETTING: Participants interviewed at home between 2010 and 2012. SAMPLE: A total of 15 162 adults aged 16-74 years (8869 women). Data reported from 6669 sexually active women. METHODS: Age-adjusted logistic regressions to examine associations between painful sex and indicators of sexual, relational, mental and physical health. MAIN OUTCOME MEASURE: Physical pain as a result of sex for ≥3 months in the past year, plus measures of symptom severity. RESULTS: Painful sex was reported by 7.5% (95% CI 6.7-8.3) of sexually active women, of whom one-quarter experienced symptoms very often or always, for ≥6 months, and causing distress. Reporting painful sex was strongly associated with other sexual function problems, notably vaginal dryness (age adjusted odds ratio 7.9; 6.17-10.12), anxiety about sex (6.34; 4.76-8.46) and lacking enjoyment in sex (6.12; 4.81-7.79). It was associated with sexual relationship factors [such as not sharing same level of interest in sex (2.56; 1.97-3.33)], as well as with adverse experiences such as non-volitional sex (2.17; 1.68-2.80). Associations were also found with measures of psychological and physical health, including depressive symptoms (1.68; 1.28-2.21). CONCLUSION: Painful sex is reported by a sizeable minority of women in Britain. Health professionals should be supported to undertake holistic assessment and treatment which takes account of the sexual, relationship and health context of symptoms. TWEETABLE ABSTRACT: Painful sex-reported by 7.5% of women in Britain-is linked to poorer sexual, physical, relational and mental health.

'If it's a medical issue I would have covered it by now': learning about fibromyalgia through the hidden curriculum: a qualitative study.

BACKGROUND: Fibromyalgia syndrome (FMS) is a long-term condition that affects between 1 and 5% of the general population and lies within the spectrum of medically unexplained symptoms (MUS). FMS can be difficult to diagnose and is usually done so as a diagnosis of exclusion. There is continuing debate regarding its legitimacy excluding other causes of symptoms. It is known that the diagnosis and management of MUS, including FMS, receives little attention in medical curricula and attitudes towards patients with FMS amongst medical professionals and trainees can be negative. The purpose of this study was to investigate how attitudes and perspectives of undergraduate medical students towards FMS are acquired during their training. METHODS: Qualitative interviews with 21 medical students were conducted to explore their views on FMS, encounters with patients with FMS, and where learning about FMS occurs. Participants were recruited from two English medical schools and the study was approved by two University Ethics committees. Interviews were digitally recorded with consent and data analysed thematically, using principles of constant comparison. RESULTS: The data were organised within three themes: i) FMS is a complex, poorly understood condition; ii) multiple sources for learning about FMS; and iii) consequences of negative attitudes for patients with FMS. CONCLUSION: Undergraduate medical students have limited understanding of, and are sceptical over the existence of FMS. These attitudes are influenced by the 'hidden curriculum' and witnessing attitudes and actions of their clinical teachers. Students interpret a lack of formal curriculum teaching around FMS to mean that it is not serious and hence a low priority. Encountering a patient, friend or family member with FMS can increase knowledge and lead to altered perceptions of the condition. Teaching and learning about FMS needs to be consistent to improve knowledge and attitudes of clinicians. Undergraduate students should be exposed to patients with FMS so that they better understand patients with FMS.

Primary care-based screening for cardiovascular risk factors in patients with psoriasis.

BACKGROUND: Studies assessing cardiovascular disease (CVD) risk factors in patients with psoriasis have been limited by selection bias, inappropriate controls or a reliance on data collected for clinical reasons. OBJECTIVES: To investigate whether screening for CVD risk factors in patients with psoriasis in primary care augments the known prevalence of CVD risk factors in a cross-sectional study. METHODS: Patients listed as having psoriasis in primary care were recruited, screened and risk assessed by QRISK2. RESULTS: In total, 287 patients attended (mean age 53 years, 57% women, 94% white British, 22% severe disease, 33% self-reported psoriatic arthritis). The proportion with known and screen-detected (previously unknown) risk factors was as follows: hypertension 35% known and 13% screen-detected; hypercholesterolaemia 32% and 37%; diabetes 6·6% and 3·1% and chronic kidney disease 1·1% and 4·5%. At least one screen-detected risk factor was found in 48% and two or more risk factors were found in 21% of patients. One in three patients (37%) not previously known to be at high risk were found to have a high (> 10%) 10-year CVD risk. Among the participants receiving treatment for known CVD risk factors, nearly half had suboptimal levels for blood pressure (46%) and cholesterol (46%). CONCLUSIONS: Cardiovascular risk factor screening of primary care-based adults with psoriasis identified a high proportion of patients (i) at high CVD risk, (ii) with screen-detected risk factors and (iii) with suboptimally managed known risk factors. These findings need to be considered alongside reports that detected limited responses of clinicians to identified risk factors before universal CVD screening can be recommended.

THERM: the Resuscitation Management score. A prognostic tool to identify critically ill patients in the emergency department.

INTRODUCTION: Prognostic scores are widely used in the emergency department (ED) to stratify risk for critically ill patients. The Prince of Wales ED Score (PEDS) was derived specifically for patients in an ED resuscitation room to predict death or intensive care unit (ICU) admission. We aimed to validate and refine this score, in comparison with other scores including the National Early Warning Score (NEWS). METHODS: This was a single-centre prospective study of adult resuscitation-room patients over 3 months. Comparison of scores was made using receiver operating characteristic analysis. Physiological and blood test variables were compared according to the composite primary outcome: admission to ICU or death within 7 days of attendance. Multivariate logistic regression was used to derive a new prediction score, which was validated in comparison with NEWS using the historic dataset from which PEDS had been derived. RESULTS: 234 patients were included; 37 were admitted to ICU or died within 7 days. PEDS performed adequately but was not superior to other scores. A simple pragmatic score, The Resuscitation Management score (THERM) was derived which outperformed NEWS in derivation and validation sets. CONCLUSIONS: PEDS is at least as good as other scores, including NEWS. However, it is unwieldy and relies on results not immediately accessible in the ED. THERM is a new score, derived and validated in an ED setting, using variables readily available, and simple to calculate and stratify. THERM outperforms NEWS and could be used in preference in critically ill ED patients.

Too tall for the tape: the weight of schoolchildren who do not fit the Broselow tape.

BACKGROUND: In paediatric resuscitation, for a rapid and accurate estimate of children's weight, the Broselow tape can be used in children who are 46-144 cm tall. The Broselow tape has previously been found to provide the most accurate estimate of children's weight internationally, but it is not known how many fall outside the range of the tape, or whether such children can be assumed to be of adult weight, or how otherwise to estimate the weight of these children. OBJECTIVES: To determine what proportion of children in different age groups falls outside the limits of the Broselow tape, how their weight compares with that of the adults and what correlates most strongly with weight in these children. METHODS: This was a population-based prospective observational study of Chinese children up to 12 years old, from schools in Hong Kong. Weight was measured to the nearest 0.2 kg, and the height, foot-length and mid-arm circumference (MAC) were measured to the nearest 0.1 cm. RESULTS: 40% of 10-year olds and 70% of 11-year olds were too tall for the tape. Their median weight was 41.9 kg. This was significantly less than the median weight of 18-year olds (55 kg, p<0.0001) in Hong Kong. The strongest correlate with weight in these children was MAC. CONCLUSIONS: The Broselow tape is inappropriate for use in most children over 10 years old. Children too tall for the tape cannot be assumed to be of adult weight; to do so would imply an average overestimate of 30%. Weight estimates in older children could be based on MAC.

Women's experiences with tailored use of a combined oral contraceptive: a qualitative study.

STUDY QUESTION: What are women's experiences with tailored use of combined oral contraceptive pills (COCPs)? SUMMARY ANSWER: Some women reported very positive experiences with tailored use of COCPs, others did not like the unpredictability about when they would bleed and some women reported increased anxiety about possible pregnancy. WHAT IS KNOWN ALREADY: While many studies have investigated views toward extended use of COCPs, little research has examined women's actual experiences with these regimens. STUDY DESIGN, SIZE, DURATION: This was a semi-structured qualitative interview study that was part of a larger randomized trial of a standard (21 daily pills followed by a 7-day pill-free interval) versus a tailored regimen (daily pills until 3-consecutive-day bleeding triggers a 3-day pill-free interval) of Microgynon 30® mcg (Ethinyl estradiol 30 mcg, Levonorgestrel 150 mcg). PARTICIPANTS/MATERIALS, SETTINGS, METHODS: Interviews were conducted with 26 women (17 in the tailored group and 9 who switched their assigned treatment group) . Data were analyzed using thematic analysis. MAIN RESULTS AND THE ROLE OF CHANCE: Women discussed positive changes associated with tailored use of COCPs, as well as some negative consequences. The major themes identified in the interview data were: ease of tailored regimen; changes in cycle-related symptoms; adjustment to reduced/absent bleeding and unpredictability about bleeding. LIMITATIONS, REASONS FOR CAUTION: The sample comprised mainly young, nulliparous women. The majority of women were using COCPs at the start of the study. WIDER IMPLICATIONS OF THE FINDINGS: Clinicians discussing extended-use regimes with patients should mention that women may need time to adjust to an extended-use regime. Future research should attempt to identify predictors of response to extended use of COCPs.

Recognition of need in health care consultations: a qualitative study of people with psoriasis.

BACKGROUND: Psoriasis is a life-long inflammatory condition that can impact on quality of life, psychological and social functioning. Previous literature suggests patient dissatisfaction with psoriasis management; however, little is known about people's specific experiences of health care consultations. OBJECTIVES: The study aimed to explore in depth the perspectives of people living with psoriasis including coping responses, self-care strategies and how consultations with health care professionals in both primary and secondary care are experienced. METHODS: Qualitative semistructured interviews were carried out with a diverse sample of 29 people with psoriasis generated purposively and recruited from community sources in North West England. Interviews were coded using Framework Analysis to produce a thematic framework incorporating key emerging issues and concepts. RESULTS: Participants experienced psoriasis as a complex condition involving physical, psychological and social challenges, as well as issues of control, but perceived that these were largely unacknowledged by practitioners in health care consultations. Practitioners were perceived as lacking knowledge and expertise in the management of psoriasis, lacking empathy with the effects of psoriasis and failing to manage it as a long-term condition. This perceived lack of support resulted in some participants withdrawing from conventional health service providers and seeking alternative sources of help. CONCLUSIONS: Psoriasis needs to be recognized and managed as a complex long-term condition with emotional and social needs that are addressed alongside appropriate diagnosis and regular reviews of treatments which may involve referrals to specialist care.

Anthropometric and physiological measurements in healthy children.

1. Normal ranges for ultrasonic cardiac output monitor-derived cardiovascular indices are derived for Chinese children aged 1 to 12 years in Hong Kong. 2. A simple formula for calculating stroke volume is constructed, but the error varies from 8 to 40%. 3. Stroke volume index and, to a lesser extent, the cardiac index generally increase from ages 1 to 5 years, but plateau or fall slightly thereafter.
