Simple, illustrated medicines information improves ARV knowledge and patient self-efficacy in limited literacy South African HIV patients:

Few studies have investigated antiretroviral (ARV) knowledge and self-efficacy in limited literacy patients. Using a randomized controlled study design, we investigated the influence of a simple pre-tested patient information leaflet (PIL) containing both text and illustrations on HIV- and ARV-related knowledge and on self-efficacy over six months in a limited literacy African population. The recruited patients were randomly allocated to either control (standard care) or intervention group (standard care plus illustrated PIL). HIV and medicines-related knowledge was evaluated with a 22-question test at baseline, one, three, and six months. Self-efficacy was assessed using a modified version of the HIV Treatment Adherence Self-Efficacy Scale

Improving the content, wording, structure and formatting of the NHS Injectable Medicines Guide (“Medusa”) with user testing

The NHS Injectable Medicines Guide (IMG) is used by nurses in >100 hospitals to guide the preparation & administration of IV medicines. Surveys suggest users find it too detailed & confusing. This may make it difficult to find relevant, unambiguous information & could lead to serious medication errors. We aimed to identify & resolve problems in two typical IMG guides via user testing

Epithelium-off corneal cross-linking surgery compared with standard care in 10- to 16-year-olds with progressive keratoconus: the KERALINK RCT

Background: Keratoconus is a disease of the cornea affecting vision that is usually first diagnosed in the first three decades. The abnormality of corneal shape and thickness tends to progress until the patient reaches approximately 30 years of age. Epithelium-off corneal cross-linking is a procedure that has been demonstrated to be effective in randomised trials in adults and observational studies in young patients. // Objectives: The KERALINK trial examined the efficacy and safety of epithelium-off corneal cross-linking, compared with standard care by spectacle or contact lens correction, for stabilisation of progressive keratoconus. // Design: In this observer-masked, randomised, controlled, parallel-group superiority trial, 60 participants aged 10–16 years with progressive keratoconus were randomised; 58 participants completed the study. Progression was defined as a 1.5 D increase in corneal power measured by maximum or mean power (K2) in the steepest corneal meridian in the study eye, measured by corneal tomography. // Setting: Referral clinics in four UK hospitals. // Interventions: Participants were randomised to corneal cross-linking plus standard care or standard care alone, with spectacle or contact lens correction as necessary for vision, and were monitored for 18 months. // Main outcome measures: The primary outcome was K2 in the study eye as a measure of the steepness of the cornea at 18 months post randomisation. Secondary outcomes included keratoconus progression, visual acuity, keratoconus apex corneal thickness and quality of life. // Results: Of 60 participants, 30 were randomised to the corneal cross-linking and standard-care groups. Of these, 30 patients in the corneal cross-linking group and 28 patients in the standard-care group were analysed. The mean (standard deviation) K2 in the study eye at 18 months post randomisation was 49.7 D (3.8 D) in the corneal cross-linking group and 53.4 D (5.8 D) in the standard-care group. The adjusted mean difference in K2 in the study eye was –3.0 D (95% confidence interval –4.93 D to –1.08 D; p = 0.002), favouring corneal cross-linking. Uncorrected and corrected differences in logMAR vision at 18 months were better in eyes receiving corneal cross-linking: –0.31 (95% confidence interval –0.50 to –0.11; p = 0.002) and –0.30 (95% confidence interval –0.48 to –0.11; p = 0.002). Keratoconus progression in the study eye occurred in two patients (7%) randomised to corneal cross-linking compared with 12 (43%) patients randomised to standard care. The unadjusted odds ratio suggests that, on average, patients in the corneal cross-linking group had 90% (odds ratio 0.1, 95% confidence interval 0.02 to 0.48; p = 0.004) lower odds of experiencing progression than those receiving standard care. Quality-of-life outcomes were similar in both groups. No adverse events were attributable to corneal cross-linking. // Limitations: Measurements of K2 in those eyes with the most significant progression were in some cases indicated as suspect by corneal topography device software. // Conclusions: Corneal cross-linking arrests progression of keratoconus in the great majority of young patients. These data support a consideration of a change in practice, such that corneal cross-linking could be considered as first-line treatment in progressive disease. If the arrest of keratoconus progression induced by corneal cross-linking is sustained in longer follow-up, there may be particular benefit in avoiding the later requirement for contact lens wear or corneal transplantation. However, keratoconus does not continue to progress in all patients receiving standard care. For future work, the most important questions to be answered are whether or not (1) the arrest of keratoconus progression induced by corneal cross-linking is maintained in the long term and (2) the proportion of those receiving standard care who show significant progression increases with time

The Debrisoft ® monofilament debridement pad for use in acute or chronic wounds: A NICE medical technology guidance

As part of its Medical Technology Evaluation Programme, the National Institute for Health and Care Excellence (NICE) invited a manufacturer to provide clinical and economic evidence for the evaluation of the Debrisoft ® monofilament debridement pad for use in acute or chronic wounds. The University of Birmingham and Brunel University, acting as a consortium, was commissioned to act as an External Assessment Centre (EAC) for NICE, independently appraising the submission. This article is an overview of the original evidence submitted, the EAC’s findings and the final NICE guidance issued. The sponsor submitted a simple cost analysis to estimate the costs of using Debrisoft® to debride wounds compared with saline and gauze, hydrogel and larvae. Separate analyses were conducted for applications in home and applications in a clinic setting. The analysis took an UK National Health Service (NHS) perspective. It incorporated the costs of the technologies and supplementary technologies (such as dressings) and the costs of their application by a district nurse. The sponsor concluded that Debrisoft® was cost saving relative to the comparators. The EAC made amendments to the sponsor analysis to correct for errors and to reflect alternative assumptions. Debrisoft® remained cost saving in most analyses and savings ranged from £77 to £222 per patient compared with hydrogel, from £97 to £347 compared with saline and gauze, and from £180 to £484 compared with larvae depending on the assumptions included in the analysis and whether debridement took place in a home or clinic setting. All analyses were severely limited by the available data on effectiveness, in particular a lack of comparative studies and that the effectiveness data for the comparators came from studies reporting different clinical endpoints compared with Debrisoft®. The Medical Technologies Advisory Committee made a positive recommendation for adoption of Debrisoft® and this has been published as a NICE medical technology guidance (MTG17).The Birmingham and Brunel Consortium is funded by NICE to act as an External Assessment Centre for the Medical Technologies Evaluation Programme

Improving recruitment to a study of telehealth management for long-term conditions in primary care: two embedded, randomised controlled trials of optimised patient information materials

Background: Patient understanding of study information is fundamental to gaining informed consent to take part in a randomised controlled trial. In order to meet the requirements of research ethics committees, patient information materials can be long and need to communicate complex messages. There is concern that standard approaches to providing patient information may deter potential participants from taking part in trials. The Systematic Techniques for Assisting Recruitment to Trials (MRC-START) research programme aims to test interventions to improve trial recruitment. The aim of this study was to investigate the effect on recruitment of optimised patient information materials (with improved readability and ease of comprehension) compared with standard materials. The study was embedded within two primary care trials involving patients with long-term conditions. Methods: The Healthlines Study involves two linked trials evaluating a telehealth intervention in patients with depression (Healthlines Depression) or raised cardiovascular disease risk (Healthlines CVD). We conducted two trials of a recruitment intervention, embedded within the Healthlines host trials. Patients identified as potentially eligible in each of the Healthlines trials were randomised to receive either the original patient information materials or optimised versions of these materials. Primary outcomes were the proportion of participants randomised (Healthlines Depression) and the proportion expressing interest in taking part (Healthlines CVD). Results: In Healthlines Depression (n = 1364), 6.3 % of patients receiving the optimised patient information materials were randomised into the study compared to 4.0 % in those receiving standard materials (OR = 1.63, 95 % CI = 1.00 to 2.67). In Healthlines CVD (n = 671) 24.0 % of those receiving optimised patient information materials responded positively to the invitation to participate, compared to 21.9 % in those receiving standard materials (OR = 1.12, 95 % CI = 0.78 to 1.61). Conclusions: Evidence from these two embedded trials suggests limited benefits of optimised patient information materials on recruitment rates, which may only be apparent in some patient populations, with no effects on other outcomes. Further embedded trials are needed to provide a more precise estimate of effect, and to explore further how effects vary by trial context, intervention, and patient population

Care homes’ use of medicines study: prevalence, causes and potential harm of medication errors in care homes for older people

Introduction: Care home residents are at particular risk from medication errors, and our objective was to determine the prevalence and potential harm of prescribing, monitoring, dispensing and administration errors in UK care homes, and to identify their causes. Methods: A prospective study of a random sample of residents within a purposive sample of homes in three areas. Errors were identified by patient interview, note review, observation of practice and examination of dispensed items. Causes were understood by observation and from theoretically framed interviews with home staff, doctors and pharmacists. Potential harm from errors was assessed by expert judgement. Results: The 256 residents recruited in 55 homes were taking a mean of 8.0 medicines. One hundred and seventy-eight (69.5%) of residents had one or more errors. The mean number per resident was 1.9 errors. The mean potential harm from prescribing, monitoring, administration and dispensing errors was 2.6, 3.7, 2.1 and 2.0 (0 = no harm, 10 = death), respectively. Contributing factors from the 89 interviews included doctors who were not accessible, did not know the residents and lacked information in homes when prescribing; home staff’s high workload, lack of medicines training and drug round interruptions; lack of team work among home, practice and pharmacy; inefficient ordering systems; inaccurate medicine records and prevalence of verbal communication; and difficult to fill (and check) medication administration systems. Conclusions: That two thirds of residents were exposed to one or more medication errors is of concern. The will to improve exists, but there is a lack of overall responsibility. Action is required from all concerned

The use of adherence aids by adults with diabetes: A cross-sectional survey

BACKGROUND: Adherence with medication taking is a major barrier to physiologic control in diabetes and many strategies for improving adherence are in use. We sought to describe the use of mnemonic devices and other adherence aids by adults with diabetes and to investigate their association with control of hyperglycemia, hyperlipidemia and hypertension. METHODS: Cross sectional survey of diabetic adults randomly selected from Primary Care practices in the Vermont Diabetes Information System. We used linear regression to examine the associations between the use of various aids and physiologic control among subjects who used oral agents for hyperglycemia, hypercholesterolemia, and hypertension. RESULTS: 289 subjects (mean age 65.4 years; 51% female) used medications for all three conditions. Adherence aids were reported by 80%. The most popular were day-of-the-week pill boxes (50%), putting the pills in a special place (41%), and associating pill taking with a daily event such as a meal, TV show, or bedtime (11%). After adjusting for age, sex, marital status, income, and education, those who used a special place had better glycemic control (A1C -0.36%; P = .04) and systolic blood pressure (-5.9 mm Hg; P = .05) than those who used no aids. Those who used a daily event had better A1C (-0.56%; P = .01) than patients who used no aids. CONCLUSION: Although adherence aids are in common use among adults with diabetes, there is little evidence that they are efficacious. In this study, we found a few statistically significant associations with adherence aids and better diabetes control. However, these findings could be attributed to multiple comparisons or unmeasured confounders. Until more rigorous evaluations are available, it seems reasonable to recommend keeping medicines in a special place for diabetic adults prescribed multiple medications

Contemporary midwifery practice: Art, science or both?

Current midwifery practice is regulated by the Nursing and Midwifery Council (NMC), whose primary role is to safeguard the public through setting standards for education and practice and regulating fitness to practise, conduct and performance through rules and codes (NMC, 2012; 2015a). Practice is informed by evidence-based guidelines developed and implemented by the National Institute for Health and Care Excellence based on hierarchies of evidence, with meta-analyses and systematic reviews being identified as the ‘gold standard’. This positivist epistemological approach as developed by Auguste Comte (1798–1857), with scientific evidence at the top of a knowledge hierarchy, fails to acknowledge the ‘art of midwifery’, where a constructivist paradigm of experiential, intuitive and tacit knowledge is used by reflective practitioners to provide high-quality care. As midwifery pre-registration education is now degree-level, is the essence of midwifery practice being ‘with woman’ providing holistic care under threat, as the drive for a systematic and analytical approach to decision-making gathers momentum
