Structured chronic primary care and health-related quality of life in chronic heart failure

Background: Structured care is proposed as a lever for improving care for patients with chronic conditions. The purpose of this study was to explore the associations of structured care characteristics, derived from the Chronic Care Model, with health-related quality of life (HRQOL) and optimal clinical management in chronic heart failure (CHF) patients in primary care, as well as the association between optimal management and HRQOL. Methods: Cross-sectional observational study using multi-level random-coefficient analyses of a representative sample of 357 patients diagnosed with CHF from 42 primary care practices in the Netherlands. We combined individual medical record data with patient and physician questionnaires. Results: There was large variation in the levels and presence of structured care elements. A 91% of physicians indicated that next appointments for CHF patients were made immediately after visits, while 11% indicated that reminders on CHF management were periodically received in their practice. Few associations were found between the organizational characteristics and optimal treatment or HRQOL. Optimal pharmacological treatment related to better quality of life (β = -11.5, P < .0001). Also, more lifestyle advice was given in practices with an appointment system allowing contact with more than one professional during the encounter (β = 1.0, P = .04). Conclusion: HRQOL and treatment quality in CHF patients were not consistently associated with characteristics of structured care in primary care practices

Assessing the Quality of Decision Support Technologies Using the International Patient Decision Aid Standards instrument (IPDASi)

Objectives To describe the development, validation and inter-rater reliability of an instrument to measure the quality of patient decision support technologies (decision aids). Design Scale development study, involving construct, item and scale development, validation and reliability testing. Setting There has been increasing use of decision support technologies – adjuncts to the discussions clinicians have with patients about difficult decisions. A global interest in developing these interventions exists among both for-profit and not-for-profit organisations. It is therefore essential to have internationally accepted standards to assess the quality of their development, process, content, potential bias and method of field testing and evaluation. Methods Scale development study, involving construct, item and scale development, validation and reliability testing. Participants Twenty-five researcher-members of the International Patient Decision Aid Standards Collaboration worked together to develop the instrument (IPDASi). In the fourth Stage (reliability study), eight raters assessed thirty randomly selected decision support technologies. Results IPDASi measures quality in 10 dimensions, using 47 items, and provides an overall quality score (scaled from 0 to 100) for each intervention. Overall IPDASi scores ranged from 33 to 82 across the decision support technologies sampled (n = 30), enabling discrimination. The inter-rater intraclass correlation for the overall quality score was 0.80. Correlations of dimension scores with the overall score were all positive (0.31 to 0.68). Cronbach's alpha values for the 8 raters ranged from 0.72 to 0.93. Cronbach's alphas based on the dimension means ranged from 0.50 to 0.81, indicating that the dimensions, although well correlated, measure different aspects of decision support technology quality. A short version (19 items) was also developed that had very similar mean scores to IPDASi and high correlation between short score and overall score 0.87 (CI 0.79 to 0.92). Conclusions This work demonstrates that IPDASi has the ability to assess the quality of decision support technologies. The existing IPDASi provides an assessment of the quality of a DST's components and will be used as a tool to provide formative advice to DSTs developers and summative assessments for those who want to compare their tools against an existing benchmark

Improving attendance for cardiovascular risk assessment in Australian general practice: an RCT of a monetary incentive for patients

Extent: 6p.Background: Preventive health care is an important part of general practice however uptake of activities by patients is variable. Monetary incentives for doctors have been used in the UK and Australia to improve rates of screening and immunisation. Few studies have focussed on incentives for patients to attend preventive health care examinations. Our objective was to investigate the use of a monetary incentive to increase patient attendance with their general practitioner for a cardiovascular risk assessment (CVRA). Methods: A pragmatic RCT was conducted in two Australian general practices. Participating GPs underwent academic detailing for cardiovascular risk assessment. 301 patients aged 40–74, who did not have cardiovascular disease, were independently randomised to receive a letter inviting them to a no cost cardiovascular risk assessment with their GP, or the same letter plus an offer of a $25 shopping voucher if they attended. An audit of patient medical records was also undertaken and a patient questionnaire administered to a sub sample of participants. Our main outcome measure was attendance for cardiovascular risk assessment. Results: In the RCT, 56/301(18.6%) patients attended for cardiovascular risk assessment, 29/182 (15.9%) in the control group and 27/119 (22.7%) in the intervention group. The estimated difference of 6.8% (95% CI: -2.5% to 16.0%) was not statistically significant, P = 0.15. The audit showed that GPs may underestimate patients’ absolute cardiovascular risk and the questionnaire that mailed invitations from GPs for a CVRA may encourage patients to attend. Conclusions: A small monetary incentive does not improve attendance for cardiovascular risk assessment. Further research should be undertaken to determine if there are other incentives that may increase attendance for preventive activities in the general practice setting.Nigel Stocks, James Allan, Oliver Frank, Sue Williams and Philip Rya

Brushing force of manual and sonic toothbrushes affects dental hard tissue abrasion

OBJECTIVES: This study aimed to determine the brushing forces applied during in vivo toothbrushing with manual and sonic toothbrushes and to analyse the effect of these brushing forces on abrasion of sound and eroded enamel and dentin in vitro. MATERIALS AND METHODS: Brushing forces of a manual and two sonic toothbrushes (low and high frequency mode) were measured in 27 adults before and after instruction of the respective brushing technique and statistically analysed by repeated measures analysis of variance (ANOVA). In the in vitro experiment, sound and eroded enamel and dentin specimens (each subgroup n = 12) were brushed in an automatic brushing machine with the respective brushing forces using a fluoridated toothpaste slurry. Abrasion was determined by profilometry and statistically analysed by one-way ANOVA. RESULTS: Average brushing force of the manual toothbrush (1.6 ± 0.3 N) was significantly higher than for the sonic toothbrushes (0.9 ± 0.2 N), which were not significantly different from each other. Brushing force prior and after instruction of the brushing technique was not significantly different. The manual toothbrush caused highest abrasion of sound and eroded dentin, but lowest on sound enamel. No significant differences were detected on eroded enamel. CONCLUSION: Brushing forces of manual and sonic toothbrushes are different and affect their abrasive capacity. CLINICAL SIGNIFICANCE: Patients with severe tooth wear and exposed and/or eroded dentin surfaces should use sonic toothbrushes to reduce abrasion, while patients without tooth wear or with erosive lesions confining only to enamel do not benefit from sonic toothbrushes with regard to abrasion

Dental plaque score reduction with an oscillating‐rotating power toothbrush and a high‐frequency sonic power toothbrush: a systematic review and meta‐analysis of single‐brushing exercises

Aim: To establish the effect of a single-brushing exercise on dental plaque removal using an oscillating-rotating power toothbrush (OR-PTB) as compared to a high-frequency sonic power toothbrush (HFS-PTB). Materials and Methods: The MEDLINE-PubMed and Cochrane-CENTRAL databases were searched up to September 2019. The inclusion criteria contained (randomized) controlled clinical trials involving healthy adult participants brushing with an OR-PTB as compared to an HFS-PTB. Plaque index (PI) scores were evaluated after a single-brushing exercise. Results: A total of 15 publications were included, representing 34 comparisons, of which 8 were professional brushing exercises and 26 participant brushing exercises. The potential risk of bias was estimated to be low. In the overall descriptive analysis of 34 comparisons, 19 comparisons showed a statistically significant difference in favour of the OR-PTB and 4 in favour of the HFS-PTB. The meta-analysis using the professional brushing study design showed a significant difference of means (DiffM) in favour of the OR-PTB (PI score) (DiffM 0.19; P <.0001) (95% CI [013; 0.25]). In those studies where the participants brushed themselves, the data were inconclusive. PI scores showed no difference between the two brushes (P =.15), while one plaque index (the Rustogi Modified Navy plaque index) indicated significant favour for the OR-PTB (DiffM 0.06; P =.002) (95% CI [0.02; 0.09]). Conclusion: Based on the estimated evidence profile, there is moderate certainty of evidence of a very small but significant beneficial effect on plaque removal after a single-brushing exercise with the OR-PTB over the HFS-PTB
