BackgroundOnline triage software is a new way to triage patients online that allows patients to describe their problem via an online form. A GP then contacts the patient to arrange either a face-to-face or telephone consultation.AimThis study aimed to explore use of online consultation software and gain insight into patients’ experiences of using online consultations, identifying potential barriers and facilitators to use.MethodThis is a mixed methods retrospective study analysing data about patient users and their associated feedback. Data from a sample of 5591 patients were quantitatively analysed to describe characteristics of users. 576 out of the 5591 users left free-text feedback comments on their experience of use. These were thematically analysed.ResultsThe highest levels of use were observed in 25–35-year olds and lowest from those aged >65. Key themes identified included convenience, consultation quality, appropriateness, resource-use and functionality. Within each, a range of subthemes were present representing both positive and negative perceptions, suggesting that experiences of using online triage varied and were often context-dependentConclusionThere are various advantages to online triage software, but these are context-dependent. Therefore, such applications should be offered as an additional way to contact the GP surgery, rather than a replacement for more established methods, to ensure appropriate and equal access for patients.

Reactive Flux

This chapter discusses a direct approach to the calculation of the rate constant k(T) that bypasses the detailed state-to-state reaction cross-sections. The method is based on the calculation of the reactive flux across a dividing surface on the potential energy surface. Versions based on classical as well as quantum mechanics are described. The classical version and its relation to Wigner’s variational theorem and recrossings of the dividing surface is discussed. Neglecting recrossings, an approximate result based on the calculation of the classical one-way flux from reactants to products is considered. Recrossings can subsequently be included via a transmission coefficient. An alternative exact expression is formulated based on a canonical average of the flux time-correlation function. It concludes with the quantum mechanical definition of the flux operator and the derivation of a relation between the rate constant and a flux correlation function.

Opening Up

Introduction: Little consideration is given to the referral and uptake of available supportive services after distress screening. However, identifying the reasons for accepting or refusing help is mandatory for implementing a screening policy. The present study explored the practical usefulness of and potential barriers to the application of distress management. Methods: 406 cancer patients were consecutively selected and asked to complete the Distress Thermometer (DT) and Problem Check List (PL). All patients with a DT score ≥6 were invited for a post-DT telephone interview with a trained psychologist. Results: The 112 patients who refused to take part were more often older, retired, at a more advanced stage of illness, and with no previous experience of psychological intervention with respect to those who accepted. Of the 78 patients with a score ≥6 who were referred to the Psycho-Oncology Service, 65.4% accepted the telephone interview. Twenty-two patients rejected the initial invitation immediately for various reasons including logistic difficulties, physical problems, and feeling embarrassed about opening up to a psychologist. Conclusions: Our study confirms that screening per sé is insufficient to deal with the problem of distress and that more emphasis should be placed on implementing referral and treatment.

COVID-19 has led to massive disruptions in societal, economic and healthcare systems globally. While COVID-19 has sparked a surge and expansion of new digital business models in different industries, healthcare has been slower to adapt to digital solutions. The majority of ophthalmology clinical practices are still operating through a traditional model of ‘brick-and-mortar’ facilities and ‘face-to-face’ patient–physician interaction. In the current climate of COVID-19, there is a need to fuel implementation of digital health models for ophthalmology. In this article, we highlight the current limitations in traditional clinical models as we confront COVID-19, review the current lack of digital initiatives in ophthalmology sphere despite the presence of COVID-19, propose new digital models of care for ophthalmology and discuss potential barriers that need to be considered for sustainable transformation to take place.

Parents Experiences

There is limited research into parents’ experiences of Intensive Interaction. Despite this, there are parents who use it and may hold unique experiences. Exploring this could provide insight into how to support parents using Intensive Interaction. Six mothers, who used Intensive Interaction with their children with intellectual disabilities and/or autism, were interviewed. Results were analysed using interpretative phenomenological analysis. The analysis yielded 10 subordinate themes which were organised into 4 superordinate themes: ‘The Connection’, ‘Bittersweet’, ‘Fighting for Support’ and ‘Challenging Underlying Low Expectations & Stigma’. Intensive Interaction was found to help some mothers feel connected with their child; they appeared to indicate that accessing timely support with Intensive Interaction was beneficial. Intensive Interaction was also perceived to challenge assumptions and stigma, but these factors were also perceived to be potential barriers to using the approach.

Potential Barriers

The European Society of Gastrointestinal Endoscopy (ESGE) has developed performance measures and established a framework for quality assessment for gastrointestinal endoscopy in Europe. Most national societies actively undertake initiatives to implement and explicitly endorse these quality indicators. Given this, the ESGE proposes that, at a national level, strong leadership should exist to disseminate and implement quality parameters. Thus, understanding the potential barriers that may vary locally is of paramount importance. The ESGE suggests that each national society should prioritise quality and standards of care in gastrointestinal endoscopy in their activities and should survey/understand which measures are a local priority to their members and make measuring quality intrinsic to daily endoscopy practice.

Background/aimsCancer burden is predicted to double by 2030 in sub-Saharan Africa; access to healthcare services for cancer management is a priority in the region. In Nigeria, National Cancer Control Plan aims to ensure >50% cancer screening of eligible populations by 2022 for all Nigerians. We describe healthcare utilisation, cancer screening activities and potential barriers to accessing cancer care within an understudied rural community-based adult population in South West Nigeria.MethodsIn April 2018, we conducted a cross-sectional study of community-based adults (>18 years) ~130 km east of Ibadan, 250 km from Lagos in Osun State, South West Nigeria. Participants completed a face-to-face survey in local dialect. We used a questionnaire to assess demographics, health status, income, medical expenditures, doctor visits and cancer screening history.ResultsWe enrolled 346 individuals: with median age of 52 years and 75% women. Of the entire cohort, 4% had medical insurance. 46% reported a major medical cost in the last year. Cancer screening activities were infrequent in eligible participants: 1.5% reported having had cervical cancer screening, 3.3% mammogram and 5% colonoscopy screening. Cancer screening assessment was less frequent in those with less income and lower education levels. Using a multivariable logistic regression model including personal income, insurance status and education, higher personal income was associated with more cancer screening activity (OR 2.7, 95% CI 1.3 to 5.7, p<0.01). Despite this, most individuals had contact with a primary healthcare doctor (52% in the last year), and over 70% access to radio and TV suggesting the opportunity to expand community-based screening interventions and awareness exists.ConclusionsDespite national increases in cancer cases, we highlight a deficiency in cancer screening and universal healthcare coverage within a community-based adult Nigerian population. Subject to availability of governmental resources, increasing financial risk protection, awareness and targeted resource allocation may help expand access in Nigeria.
