Supporting patients to self-monitor their oral anticoagulation therapy: recommendations based on a qualitative study of patients' experiences.

BACKGROUND: Clinical trials suggest that oral anticoagulation therapy (OAT) self-monitoring is safe and effective, however little is known about the patient experience of this process. There is a lack of understanding about how best to train and support patients embarking on OAT self-monitoring. AIM: To collect in-depth information about patients' experiences of OAT self-monitoring outside of clinical trial conditions and to produce a set of recommendations on how best to support such patients. DESIGN AND SETTING: Semi-structured qualitative interviews with patients who self-monitor and live in England. METHOD: In total, 26 of the 267 (9.7%) who participated in the Cohort study of Anticoagulation Self-Monitoring (CASM) and were still self-monitoring after 12 months' follow-up were interviewed. Topics discussed included experiences of OAT self-monitoring, healthcare support, training, and decision making. Framework analysis was used. RESULTS: Following initial problems using the monitoring device, interviewees described a mostly positive experience. Although less effort was expended attending monitoring appointments with health professionals, effort was required to conduct self-monitoring tests and to interpret and act on the results. Desire to self-manage was variable, especially when dosing advice systems worked promptly and reliably. Interviewees overcame patchy healthcare system knowledge and support of self-monitoring by educating themselves. Family and friends provided support with learning to use the monitor and managing OAT dosage adjustments. CONCLUSION: Better, more-consistent training and health-service support would have alleviated a number of problems encountered by these patients who were self-monitoring. This training and support will become even more important if self-monitoring becomes more accessible to the general population of people on OAT

Cohort study of Anticoagulation Self-Monitoring (CASM): a prospective study of its effectiveness in the community.

BACKGROUND: Trials show that oral anticoagulation therapy (OAT) substantially reduces thromboembolic events without an increase in major haemorrhagic events, but it is not known whether these results translate into routine practice. AIM: To estimate the current levels of control and adverse events in patients self-monitoring OAT, explore the factors that predict success, and determine whether the level of side effects reported from randomised controlled trials are translated to a non-selected population. DESIGN AND SETTING: Prospective cohort study in the UK. METHOD: Participants were aged ≥18 years and registered with a GP. Main outcomes were the proportion of participants, over 12 months, who were still self-monitoring, had not experienced adverse events, and had achieved >80% of time in therapeutic range (TTR). RESULTS: In total, 296 participants were recruited; their median age was 61 years and 55.1% were male. Participants were predominately professional or held a university qualification (82.7%). At 12 months, 267 (90.2%) were still self-monitoring. Mean TTR was 75.3% (standard deviation 16.9).Six serious and two minor adverse events were reported by GPs. Only 45.9% of participants received any in-person training at the outset. Increased age (P = 0.027), general wellbeing (EQ-5D visual score, P = 0.020), and lower target international normalised range (INR, P = 0.032) were all associated with high (>80% TTR) levels of control. CONCLUSION: The findings show that, even with little training, people on OAT can successfully self-monitor, and even self-manage, their INR. TTR was shown to improve with age. However, widespread use of self-monitoring of INR may be limited by the initial costs, as well as a lack of training and support at the outset

Impact of self-funding on patient experience of oral anticoagulation self-monitoring: a qualitative study.

OBJECTIVE: To explore the impact self-funding has on patient experience of oral anticoagulation therapy self-monitoring. DESIGN: Semistructured, qualitative interviews were conducted. Transcripts were analysed thematically using constant comparison. SETTING: England. PARTICIPANTS: Interviewees were participants of the Cohort Study of Anticoagulation Self-Monitoring (CASM). Cohort members were recruited as they bought a monitor from the major manufacturer in the UK. A purposive sample was invited to be interviewed on completion of the 12-month cohort follow-up. DATA: Patient narratives on their experiences of self-monitoring their oral anticoagulation therapy in non-trial conditions. RESULTS: 26 interviews were completed. Interviewees viewed purchasing the monitoring device as a long-term commitment balancing the limitations of clinic-based monitoring against the cost. They were unable to try out the monitor prior to purchase and therefore had to be confident in their own ability to use it. The variable provision of self-monitoring equipment caused resentment, and interviewees were uncomfortable negotiating with healthcare professionals. High test strip usage while learning how to use the monitor caused anxiety that was exacerbated by worries about their cost. However, self-funding did mean that interviewees felt a sense of ownership and were determined to persevere to overcome problems. CONCLUSIONS: Self-funding has negative implications in terms of equity of access; however, the money invested acts as a barrier to discontinuation. If oral anticoagulation therapy self-monitoring devices and consumables were provided free of charge in routine care, the training and support available in England may need to be reviewed to prevent discontinuation rates rising to those observed in clinical trials

Can physical assessment techniques aid diagnosis in people with chronic fatigue syndrome/myalgic encephalomyelitis? A diagnostic accuracy study

Objective: To assess 5 physical signs to see whether they can assist in the screening of patients with CFS/ME, and potentially lead to quicker treatment. Methods: This was a diagnostic accuracy study with inter-rater agreement assessment. Participants recruited from 2 NHS hospitals, local CFS/ME support groups and the community were examined by three practitioners on the same day in a randomized order. Two Allied Health Professionals (AHPs) performed independent examinations of physical signs including; postural/mechanical disturbances of the thoracic spine, breast varicosities, tender Perrin’s Point, tender coeliac plexus and dampened cranial flow. A physician conducted a standard clinical neurological and rheumatological assessment, whilst looking for patterns of illness behaviour. Each examination lasted approximately 20 minutes. Results: Ninety-four participants were assessed, 52 CFS/ME patients and 42 non-CFS/ME controls, aged 18-60. Cohen’s kappa revealed agreement between the AHPs was substantial for presence of the tender coeliac plexus (κ=0.65, p<0.001) and moderate for postural/mechanical disturbance of the thoracic spine (κ=0.57, p<0.001) and Perrin’s point (κ=0.56, p<0.001). A McNemar’s test found no statistically significant bias in the diagnosis by the experienced AHP relative to actual diagnosis, (p=1.0) and a marginally non-significant bias by the newly trained AHP, p=0.052. There was however, a significant bias in the diagnosis made by the physician relative to actual diagnosis, (p<0.001), indicating poor diagnostic utility of the clinical neurological and rheumatological assessment. Conclusions: Using the physical signs appears to improve the accuracy of identifying people with CFS/ME and shows agreement with current diagnostic techniques, however the present study concludes that only 2 of these may be needed. Examining for physical signs is both quick and simple for the AHP and may be used as an efficient screening tool for CFS/ME. This is a small single centre study and therefore further validation in other centres and larger populations is needed

Language control and parallel recovery of language in individuals with aphasia

Background: The causal basis of the different patterns of language recovery following stroke in bilingual speakers is not well understood. Our approach distinguishes the representation of language from the mechanisms involved in its control. Previous studies have suggested that difficulties in language control can explain selective aphasia in one language as well as pathological switching between languages. Here we test the hypothesis that difficulties in managing and resolving competition will also be observed in those who are equally impaired in both their languages even in the absence of pathological switching. Aims: To examine difficulties in language control in bilingual individuals with parallel recovery in aphasia and to compare their performance on different types of conflict task. Methods & procedures: Two right-handed, non-native English-speaking participants who showed parallel recovery of two languages after stroke and a group of non-native English-speaking, bilingual controls described a scene in English and in their first language and completed three explicit conflict tasks. Two of these were verbal conflict tasks: a lexical decision task in English, in which individuals distinguished English words from non-words, and a Stroop task, in English and in their first language. The third conflict task was a non-verbal flanker task. Outcomes & Results: Both participants with aphasia were impaired in the picture description task in English and in their first language but showed different patterns of impairment on the conflict tasks. For the participant with left subcortical damage, conflict was abnormally high during the verbal tasks (lexical decision and Stroop) but not during the non-verbal flanker task. In contrast, for the participant with extensive left parietal damage, conflict was less abnormal during the Stroop task than the flanker or lexical decision task. Conclusions: Our data reveal two distinct control impairments associated with parallel recovery. We stress the need to explore the precise nature of control problems and how control is implemented in order to develop fuller causal accounts of language recovery patterns in bilingual aphasia

Conference: Reparations in the Inter-American System: A Comparative Approach Conference

This publication will enhance the understanding of what we call the law of reparations, developed in the Inter-American Court and Commission of Human Rights. Reparations have a special meaning for the victims of human rights violations and, in particular, the victims of mass and gross violations that took place in this hemisphere during the twentieth century. For those victims and their family members, reestablishing the rights as if no violation had occurred is not possible. Accordingly, to them, avoiding the repetition of those violations in the future is of paramount importance. In achieving that goal, what the victims want is the investigation and punishment of those who appear guilty as an essential component of the law of compensation. Material and moral damages, symbolic measures of redress, as well as legislative changes when needed are also crucially important. The inter-American system’s supervisory organs, within the limits of their jurisdiction, and in particular through the interpretation of Article 63 of the American Convention, have creatively developed the law of reparations within the Americas. As a result of the decisions from the supervisory organs, what has emerged is perhaps the most comprehensive legal regime on reparations developed in the human rights field in international law.
