Using telemedicine to improve access, cost and quality of secondary care for people in prison in England: a hybrid type 2 implementation effectiveness study.

INTRODUCTION: People in prison tend to experience poorer health, access to healthcare services and health outcomes than the general population. Use of video consultations (telemedicine) has been proven effective at improving the access, cost and quality of secondary care for prisoners in the USA and Australia. Implementation and use in English prison settings has been limited to date despite political drivers for change. We plan to research the implementation of a new prison-hospital telemedicine model in an English county to understand what factors drive or hinder implementation and whether the model can improve healthcare outcomes as demonstrated in other contextual settings. METHODS AND ANALYSIS: We will undertake a hybrid type 2 implementation effectiveness study to gather evidence on both clinical and implementation outcomes. Data collection will be guided by the theoretical constructs of Normalisation Process Theory. We will prospectively collect data through: (1) prisoner/patient focus groups, interviews and questionnaires, (2) prison healthcare, hospital and wider prison staff interviews and questionnaires, (3) routine quality improvement and service evaluation data. Up to four prisons and three hospital settings in Surrey (England) will be included in the telemedicine research, dependent on their telemedicine readiness during the study period. Prisons proposed include male and female prisoners, remand (not yet sentenced) and sentenced individuals and different security categorisations. In addition, focus groups in five telemedicine naïve prisons will provide information on patient preconceptions and concerns surrounding telemedicine. ETHICS AND DISSEMINATION: This study has received National Health Service Research Ethics Committee, Her Majesty's Prison and Probation Service National Research Committee and Health Research Authority approval. Dissemination of results will take place through peer-reviewed journals, conferences and existing health and justice networks.

A framework to determine the effectiveness of dietary exposure mitigation to chemical contaminants.

In order to ensure the food safety, risk managers may implement measures to reduce human exposure to contaminants via food consumption. The evaluation of the effect of a measure is often an overlooked step in risk analysis process. The aim of this study was to develop a systematic approach for determining the effectiveness of mitigation measures to reduce dietary exposure to chemical contaminants. Based on expert opinion, a general framework for evaluation of the effectiveness of measures to reduce human exposure to food contaminants was developed. The general outline was refined by application to three different cases: 1) methyl mercury in fish and fish products, 2) deoxynivalenol in cereal grains, and 3) furan in heated products. It was found that many uncertainties and natural variations exist, which make it difficult to assess the impact of the mitigation measure. Whenever possible, quantitative methods should be used to describe the current variation and uncertainty. Additional data should be collected to cover natural variability and reduce uncertainty. For the time being, it is always better for the risk manager to have access to all available information, including an assessment of uncertainty; however, the proposed methodology provides a conceptual framework for addressing these systematically.

Acceptability and feasibility of universal offer of rapid point of care testing for HIV in an acute admissions unit: results of the RAPID project.

BACKGROUND: UK guidance recommend all acute medical admissions be offered an HIV test. Our aim was to determine whether a dedicated staff member using a multimedia tool, a model found to be effective in the USA, is an acceptable, feasible, and cost-effective model when translated to a UK setting. DESIGN: Between 14(th) Jan to 12(th) May 2010, a Health advisor (HA) approached 19-65 year olds at a central London acute medical admissions unit (AAU) and offered a rapid HIV point of care test (POCT) with the aid of an educational video. Patients with negative results had the option to watch a post-test video providing risk-reduction information. For reactive results the HA arranged a confirmatory test, and ensured linkage into HIV specialist care. Feasibility and acceptability were assessed through surveys and uptake rates. Costs per case of HIV identified were established. RESULTS: Of the 606 eligible people admitted during the pilot period, 324 (53.5%) could not be approached or testing was deemed inappropriate. In total 23.0% of eligible admissions had an HIV POCT. Of the patients who watched the video and had not recently tested for HIV, 93.6% (131/140) agreed to an HIV test; four further patients had an HIV test but did not watch the video. Three tests (2.2%, 3/135) were reactive and all were confirmed HIV positive on laboratory testing. 97.5% felt HIV testing in this setting was appropriate, and 90.1% liked receiving the information via video. The cost per patient of the intervention was £21. DISCUSSION: Universal POCT HIV testing in an acute medical setting, facilitated by an educational video and dedicated staff appears to be acceptable, feasible, effective, and low cost. These findings support the recommendation of HIV testing all admissions to AAU in high prevalence settings, although with the model used a significant proportion remained untested.

Clinical and behavioural aspects of aging with HIV infection.

Scant attention has been paid to the effects of ageing and HIV. This study examined age distribution and explored the impact of age on the experience of illness. One thousand and seven consecutive attenders at five UK HIV clinics were approached, 904 met inclusion criteria and 778 agreed to participate (86% response rate). They provided detailed information on demographics, experience of illness, physical and psychological symptoms, quality of life, treatment experience and doctor-patient communications. Twelve percent were aged over 50. There were significantly more males in the over 50s (86% vs. 75%), more gay males x(2) = 7, p = 0.04 and fewer females (14% vs. 25%) x(2) = 5; p = 0.03. No significant differences were found on measures of education, employment or migration status or physical symptom experience. The older group had significantly lower psychological and global burden scores and were more likely to take antiretrovirals (88% vs. 79%; p = 0.04). Triggers for treatment switching showed older participants significantly less burdened by food restrictions, pill burden, taste, nausea, diarrhoea, sleep disturbance, concentration problems, anxiety depression, skin rashes, liver complaints or a need for a simpler regimen. The older group were similar in employment, education and disclosure, but complained less and reported much higher tolerance.
