Assessing the contribution of prescribing in primary care by nurses and professionals allied to medicine: a systematic review of literature

BackgroundSafe and timely access to effective and appropriate medication through primary care settings is a major concern for all countries addressing both acute and chronic disease burdens. Legislation for nurses and other professionals allied to medicine to prescribe exists in a minority of countries, with more considering introducing legislation. Although there is variation in the range of medicines permitted to be prescribed, questions remain as to the contribution prescribing by nurses and professionals allied to medicine makes to the care of patients in primary care and what is the evidence on which clinicians, commissioners of services and policy makers can consider this innovation.MethodsA integrative review of literature on non-medical prescribing in primary care was undertaken guided by dimensions of health care quality: effectiveness, acceptability, efficiency and access.Results19 papers of 17 empirical studies were identified which provided evidence of patient outcome of non medical prescribing in primary care settings. The majority were undertaken in the UK with only one each from the USA, Canada, Botswana and Zimbabwe. Only two studies investigated clinical outcomes of non-medical prescribing. Seven papers reported on qualitative designs and four of these had fewer than ten participants. Most studies reported that non medical prescribing was widely accepted and viewed positively by patients and professionals.ConclusionsPrimary health care is the setting where timely access to safe and appropriate medicines is most critical for the well-being of any population. The gradual growth over time of legislative authority and in the numbers of non-medical prescribers, particularly nurses, in some countries suggests that the acceptability of non-medical prescribing is based on the perceived value to the health care system as a whole. Our review suggests that there are substantial gaps in the knowledge base to help evidence based policy making in this arena. We suggest that future studies of non-medical prescribing in primary care focus on the broad range of patient and health service outcomes and include economic dimensions.

An argument against the focus on community resilience in public health

BackgroundIt has been suggested that Public Health professionals focus on community resilience in tackling chronic problems, such as poverty and deprivation; is this approach useful?DiscussionResilience is always i) of something ii) to something iii) to an endpoint, as in i) a rubber ball, ii) to a blunt force, iii) to its original shape. “Community resilience” might be: of a neighbourhood, to a flu pandemic, with the endpoint, to return to normality. In these two examples, the endpoint is as-you-were. This is unsuitable for some examples of resilience. A child that is resilient to an abusive upbringing has an endpoint of living a happy life despite that upbringing: this is an as-you-should-be endpoint. Similarly, a chronically deprived community cannot have the endpoint of returning to chronic deprivation: so what is its endpoint? Roughly, it is an as-you-should-be endpoint: to provide an environment for inhabitants to live well. Thus resilient communities will be those that do this in the face of challenges. How can they be identified?One method uses statistical outliers, neighbourhoods that do better than would be expected on a range of outcomes given a range of stressors. This method tells us that a neighbourhood is resilient but not why it is. In response, a number of researchers have attributed characteristics to resilient communities; however, these generally fail to distinguish characteristics of a good community from those of a resilient one. Making this distinction is difficult and we have not seen it successfully done; more importantly, it is arguably unnecessary.There already exist approaches in Public Health to assessing and developing communities faced with chronic problems, typically tied to notions such as Social Capital. Community resilience to chronic problems, if it makes sense at all, is likely to be a property that emerges from the various assets in a community such as human capital, built capital and natural capital.SummaryPublic Health professionals working with deprived neighbourhoods would be better to focus on what neighbourhoods have or could develop as social capital for living well, rather than on the vague and tangential notion of community resilience.

Quality and acceptability of measures of exercise adherence in musculoskeletal settings: a systematic review

Objective. To recommend robust and relevant measures of exercise adherence for application in the musculoskeletal field. Method. A systematic review of measures was conducted in two phases. Phase 1 sought to identify all reproducible measures used to assess exercise adherence in a musculoskeletal setting. Phase 2 identified published evidence of measurement and practical properties of identified measures. Eight databases were searched (from inception to February 2016). Study quality was assessed against the Consensus-based Standards for the Selection of Health Measurement Instruments guidelines. Measurement quality was assessed against accepted standards. Results. Phase 1: from 8511 records, 326 full-text articles were reviewed; 45 reproducible measures were identified. Phase 2: from 2977 records, 110 full-text articles were assessed for eligibility; 10 articles provided evidence of measurement/practical properties for just seven measures. Six were exercise adherence-specific measures; one was specific to physical activity but applied as a measure of exercise adherence. Evidence of essential measurement and practical properties was mostly limited or not available. Assessment of relevance and comprehensiveness was largely absent and there was no evidence of patient involvement during the development or evaluation of any measure. Conclusion. The significant methodological and quality issues encountered prevent the clear recommendation of any measure; future applications should be undertaken cautiously until greater clarity of the conceptual underpinning of each measure is provided and acceptable evidence of essential measurement properties is established. Future research should seek to engage collaboratively with relevant stakeholders to ensure that exercise adherence assessment is high quality, relevant and acceptable.

Recovery-based staff training intervention within mental health rehabilitation units: a two-stage analysis using realistic evaluation principles and framework approach.

BackgroundLong-term change in recovery-based practice in mental health rehabilitation is a research priority.MethodsWe used a qualitative case study analysis using a blend of traditional ‘framework’ analysis and ‘realist’ approaches to carry out an evaluation of a recovery-focused staff training intervention within three purposively selected mental health rehabilitation units. We maximised the validity of the data by triangulating multiple data sources.ResultsWe found that organisational culture and embedding of a change management programme in routine practice were reported as key influences in sustaining change in practice. The qualitative study generated 10 recommendations on how to achieve long-term change in practice including addressing pre-existing organisational issues and synergising concurrent change programmes.ConclusionsWe propose that a recovery-focused staff training intervention requires clear leadership and integration with any existing change management programmes to facilitate sustained improvements in routine practice.

Appointment reminder systems are effective but not optimal: results of a systematic review and evidence synthesis employing realist principles.

Missed appointments are an avoidable cost and resource inefficiency which impact upon the health of the patient and treatment outcomes. Health care services are increasingly utilizing reminder systems to manage these negative effects. This study explores the effectiveness of reminder systems for promoting attendance, cancellations, and rescheduling of appointments across all health care settings and for particular patient groups and the contextual factors which indicate that reminders are being employed sub-optimally. We used three inter-related reviews of quantitative and qualitative evidence. Firstly, using pre-existing models and theories, we developed a conceptual framework to inform our understanding of the contexts and mechanisms which influence reminder effectiveness. Secondly, we performed a review following Centre for Reviews and Dissemination guidelines to investigate the effectiveness of different methods of reminding patients to attend health service appointments. Finally, to supplement the effectiveness information, we completed a review informed by realist principles to identify factors likely to influence non-attendance behaviors and the effectiveness of reminders. We found consistent evidence that all types of reminder systems are effective at improving appointment attendance across a range of health care settings and patient populations. Reminder systems may also increase cancellation and rescheduling of unwanted appointments. “Reminder plus”, which provides additional information beyond the reminder function may be more effective than simple reminders (ie, date, time, place) at reducing non-attendance at appointments in particular circumstances. We identified six areas of inefficiency which indicate that reminder systems are being used sub-optimally. Unless otherwise indicated, all patients should receive a reminder to facilitate attendance at their health care appointment. The choice of reminder system should be tailored to the individual service. To optimize appointment and reminder systems, health care services need supportive administrative processes to enhance attendance, cancellation, rescheduling, and re-allocation of appointments to other patients.

Honour based violence as a global public health problem: a critical review of literature

Purpose “Honour”-based violence (HBV), a form of gender-based violence (GBV), has received increasing interest from media, human rights organisations, academics and the public. A significant increase in the occurrence and reporting of HBV in many parts of the world and its detrimental impact on the health and well-being of women, girls, communities and wider society; marks it as a major public health concern. However, awareness and recognition of HBV in the field of public health is low in many countries and there is little known about its nature, roots and distribution. The paper aims to discuss these issues. Design/methodology/approach The literature was searched using the Scopus database and a series of search terms related to HBV, GBV and health and well-being. Findings Definition of HBV and its forms is varied across cultures. There is a lack of consensus on how HBV can be identified over other forms of violence and no explicit theoretical perspectives have been sufficiently developed to deepen the understanding of HBV. Although the findings from the review suggest that HBV forms and patterns may be regionally distinct, causes emanate from gender-based and socio-economic inequalities. Research limitations/implications This review has limitations in that it included only English and Spanish language papers and those accessed through Scopus; it therefore may have excluded papers from other languages, countries and databases. Another major weakness in this review was a lack of papers specifically dedicated to HBV. Despite these weaknesses the paper is an attempt to raise awareness and recognition of HBV in public health research, policy and practice domain. Originality/value The findings from the review highlight the complexity of tackling HBV in a globalised world. They also provide insights on how a public health model can be used to analyse both the causes and prevention of HBV. Further, a non-culturalised, unprejudiced and inclusive definition is required to flag-up and record HBV cases.

Developing a framework for estimating the potential impact of obesity interventions in a European city

Obesity is a global challenge for healthy populations. It has given rise to a wide range of public health interventions, focusing on supportive environments and lifestyle change, including diet, physical activity and behavioural change initiatives. Impact is variable. However, more evidence is slowly becoming available and is being used to develop new interventions. In a period of austerity, momentum is building to review these initiatives and understand what they do, how they do it and how they fit together. Our project seeks to develop a relatively straight forward systematic framework using readily accessible data to map the complex web of initiatives at a policy, population, group and individual level aiming to promote healthy lifestyles, diet and physical activity levels or to reduce obesity through medical treatments in a city or municipality population. It produces a system for classifying different types of interventions into groupings which will enable commissioners to assess the scope and distribution of interventions and make a judgement about gaps in provision and the likely impact on mean body mass index (BMI) as a proxy measure for health. Estimated impact in each level or type of intervention is based upon a summary of the scientific evidence of clinical and/or cost effectiveness. Finally it seeks, where possible, to quantify the potential effects of different types of interventions on BMI and produce a cost per unit of BMI reduced. This approach is less sophisticated but identifies the areas where more sophisticated evaluation would add value.
