Are General Practitioners Good for Endogenous Supply and Health
We investigate the impact of area general practitioner (GP) supply on individual health in England. If no allowance is made for the endogeneity of GP supply, the effect is positive but not statistically significant. When GP supply is instrumented by age related capitation the effect is markedly greater and statistically significant. A 10% increase in GP supply leads to an increase in the proportion of the population reporting very good health by 6% from 36%. The estimated cost per quality adjusted life year gained from an additional GP is between £527 and £5740.

Reasons for non-adherence to cardiometabolic medications, and acceptability of an interactive voice response intervention in patients with hypertension and type 2 diabetes in primary care: a qualitative study.
OBJECTIVES: This study explored the reasons for patients' non-adherence to cardiometabolic medications, and tested the acceptability of the interactive voice response (IVR) as a way to address these reasons, and support patients, between primary care consultations. DESIGN, METHOD, PARTICIPANTS AND SETTING: The study included face-to-face interviews with 19 patients with hypertension and/or type 2 diabetes mellitus, selected from primary care databases, and presumed to be non-adherent. Thirteen of these patients pretested elements of the IVR intervention few months later, using a think-aloud protocol. Five practice nurses were interviewed. Data were analysed using multiperspective, and longitudinalthematic analysis. RESULTS: Negative beliefs about taking medications, the complexity of prescribed medication regimens, and the limited ability to cope with the underlying affective state, within challenging contexts, were mentioned as important reasons for non-adherence. Nurses reported time constraints to address each patient's different reasons for non-adherence, and limited efficacy to support patients, between primary care consultations. Patients gave positive experiential feedback about the IVR messages as a way to support them take their medicines, and provided recommendations for intervention content and delivery mode. Specifically, they liked the voice delivering the messages and the voice recognition software. For intervention content, they preferred messages that were tailored, and included messages with 'information about health consequences', 'action plans', or simple reminders for performing the behaviour. CONCLUSIONS: Patients with hypertension and/or type 2 diabetes, and practice nurses, suggested messages tailored to each patient's reasons for non-adherence. Participants recommended IVR as an acceptable platform to support adherence to cardiometabolic medications between primary care consultations. Future studies could usefully test the acceptability, and feasibility, of tailored IVR interventions to support medication adherence, as an adjunct to primary care
Automated telecommunication interventions to promote adherence to cardio-metabolic medications: meta-analysis of effectiveness and meta-regression of behaviour change techniques.
Automated telecommunication interventions, including short message service and interactive voice response, are increasingly being used to promote adherence to medications prescribed for cardio-metabolic conditions. This systematic review aimed to comprehensively assess the effectiveness of such interventions to support medication adherence, and to identify the behaviour change techniques (BCTs) and other intervention characteristics that are positively associated with greater intervention effectiveness. Meta-analysis of 17 randomised controlled trials showed a small but statistically significant effect on medication adherence, OR = 1.89, 95% CI [1.51, 2.36], I2 = 89%, N = 25,101. Multivariable meta-regression analysis including eight BCTs explained 88% of the observed variance in effect size (ES). The BCTs 'tailored' and 'information about health consequences' were positively and significantly associated with ES. Future studies could explore whether the inclusion of these and/or additional techniques (e.g., 'implementation intentions') would increase the effect of automated telecommunication interventions, using rigorous designs and objective outcome measures

Effectiveness of Acceptance and Commitment Therapy (ACT) interventions for promoting physical activity: a systematic review and meta-analysis.
Physical inactivity is a key risk factor for non-communicable diseases, and there is a need for interventions to increase the adoption and maintenance of regular physical activity. Interventions based on Acceptance and Commitment (ACT) have shown promise for promoting a range of health behaviours, including physical activity. The aims of this review were to (1) determine the effectiveness of ACT interventions for physical activity; and (2) identify the ACT processes, behaviour change techniques (BCTs) and intervention characteristics associated with ACT interventions. Eight electronic databases were searched for ACT interventions that aimed to increase physical activity. Seven eligible studies were included in the systematic review, and ACT processes, Behaviour Change Techniques and other intervention components and characteristics of the included interventions were coded. Six studies were randomised controlled trials that were included in a random-effects meta-analysis, which indicated small-to-moderate effects on physical activity (SMD = 0.32, 95% CI (0.07, 0.57), p = 0.01). ACT interventions show promise for increasing physical activity, but very few of the 'active ingredients' of ACT interventions could be characterised as BCTs. Future development of ACT interventions for physical activity should attempt to describe and name the ACT processes targeted by the intervention, and the BCTs used to target those processes
Determination of high temperature strains using a PC based vision system
With the widespread availability of video digitizers and cheap personal computers, the use of computer vision as an experimental tool is becoming common place. These systems are being used to make a wide variety of measurements that range from simple surface characterization to velocity profiles. The Sub-Pixel Digital Image Correlation technique has been developed to measure full field displacement and gradients of the surface of an object subjected to a driving force. The technique has shown its utility by measuring the deformation and movement of objects that range from simple translation to fluid velocity profiles to crack tip deformation of solid rocket fuel. This technique has recently been improved and used to measure the surface displacement field of an object at high temperature. The development of a PC based Sub-Pixel Digital Image Correlation system has yielded an accurate and easy to use system for measuring surface displacements and gradients. Experiments have been performed to show the system is viable for measuring thermal strain
Interactive voice response interventions targeting behaviour change: a systematic literature review with meta-analysis and meta-regression.
OBJECTIVE: A number of promising automated behaviour change interventions have been developed using advanced phone technology. This paper reviewed the effectiveness of interactive voice response (IVR)-based interventions designed to promote changes in specific health behaviours. METHODS: A systematic literature review of papers published between January 1990 and September 2017 in MEDLINE, CINAHL, Embase, PsycINFO, SCOPUS and the Cochrane Central Register of Controlled Trials (CENTRAL) was conducted. From the total of 2546 papers identified, 15 randomised control trials (RCTs) met the eligibility criteria and were included in a random effects meta-analysis. Meta-regression analysis was used to explore whether behaviour change techniques (BCTs) that were used in the interventions were associated with intervention effectiveness. RESULTS: Meta-analysis of 15 RCTs showed that IVR-based interventions had small but significant effects on promoting medication adherence (OR=1.527, 95% CI 1.207 to 1.932, k=9, p=0.000) and physical activity (Hedges' g=0.254, 95% CI 0.068 to 0.439, k=3, p=0.007). No effects were found for alcohol (Hedges' g=-0.077, 95% CI -0.162 to 0.007, k=4, p=0.073) or diet (Hedges' g=0.130, 95% CI -0.088 to 0.347, k=2, p=0.242). In the medication adherence studies, multivariable meta-regression including six BCTs explained 100% of the observed variance in effect size, but only the BCT 'information about health consequences' was significantly associated with effect size (β=0.690, SE=0.199, 95% CI 0.29 to 1.08, p=0.000). CONCLUSION: IVR-based interventions appear promising in changing specific health behaviours, such as medication adherence and physical activity. However, more studies are needed to elucidate further the combination of active components of IVR interventions that make them effective and test their feasibility and effectiveness using robust designs and objective outcome measures.This study was part of the first author’s dissertation in public health at University of Cambridge, funded by the Medical Research Council, UK

Computer-tailored smoking cessation advice matched to reading ability: Perceptions of participants from the ESCAPE trial.
OBJECTIVE: To explore perceptions of computer-tailored advice reports for smoking cessation matched to the recipient's reading level. METHODS: Current cigarette smokers in the UK aged 18-65 who completed a Smoking Behavior Questionnaire (n=6911) were randomized to receive standard generic materials or standard materials plus computer-tailored reports adapted to the recipient's reading level. Smoking status and perception of the reports was assessed at a 6-month follow-up. 4677 participants were included in the analysis. RESULTS: 53.3% were categorized into the easy reading group (ERG). The relative benefit of the intervention for prolonged 3-month abstinence was more marked in the ERG (2.6%/1.9%, OR=1.50) than in the standard reading group (SRG) (4.0%/3.8%, OR=1.05), although the interaction was not statistically significant. Participants in the Intervention group perceived the standard materials more positively than did those in the Control group, and participants in the ERG perceived both the generic material and the tailored report more positively. CONCLUSIONS: The easy reading version of this brief self-help intervention was better perceived than the standard version, and appeared to have a small, but promising effect in smokers with a lower literacy level. PRACTICE IMPLICATIONS: An association between reading level and deprivation emphasizes the need to adapt smoking cessation materials to address the needs of smokers with lower literacy
Opinions on the use of technology to improve tablet taking in >65-year-old patients on cardiovascular medications.
Objective This study was performed to evaluate the perceptions of the use of technology to improve cardiovascular medicine taking among patients aged >65 years. Methods This qualitative study used focus groups with people aged >65 years taking cardiovascular medications from two East London community centres. Thematic analysis was informed by the Perceptions and Practicalities Approach framework. Results Participants welcomed technologies they considered familiar, accessible, and easy to use. They valued the opportunity to receive alerts to help with forgetting and monitoring their treatment. More advanced technologies such as ingestible sensor systems were considered helpful for elderly people with significant cognitive impairments still living in the community because of improved monitoring by caregivers and clinicians and prolonging independence. Although generally adapting to the increase in technology in everyday life, participants raised a number of concerns that included potential reduction in face-to-face communication, data security, becoming dependent on technology, and worrying about the consequences of technological failure. Conclusions Participants raised a number of concerns and practical barriers that would need to be addressed for technologies to be accepted and adopted in this patient group
