Containing antibiotic resistance: decreased antibiotic-resistant coliform urinary tract infections with reduction in antibiotic prescribing by general practices.

BACKGROUND: GPs are urged to prescribe antibiotics less frequently, despite lack of evidence linking reduced antibiotic prescribing with reductions in resistance at a local level. AIM: To investigate associations between changes in antibiotic dispensing and changes in antibiotic resistance at general-practice level. DESIGN OF STUDY: Seven-year study of dispensed antibiotics and antibiotic resistance in coliform isolates from urine samples routinely submitted from general practice. SETTING: General practices in Wales. METHOD: Multilevel modelling of trends in resistance to ampicillin and trimethoprim, and changes in practice total antibiotic dispensing and amoxicillin and trimethoprim dispensing. RESULTS: The primary analysis included data on 164 225 coliform isolates from urine samples submitted from 240 general practices over the 7-year study period. These practices served a population of 1.7 million patients. The quartile of practices that had the greatest decrease in total antibiotic dispensing demonstrated a 5.2% reduction in ampicillin resistance over the 7-year period with changes of 0.4%, 2.4%, and -0.3% in the other three quartiles. There was a statistically significant overall decrease in ampicillin resistance of 1.03% (95% confidence interval [CI] = 0.37 to 1.67%) per decrease of 50 amoxicillin items dispensed per 1000 patients per annum. There were also significant reductions in trimethoprim resistance in the two quartiles of practices that reduced total antibiotic dispensing most compared with those that reduced it least, with an overall decrease in trimethoprim resistance of 1.08% (95% CI = 0.065 to 2.10%) per decrease of 20 trimethoprim items dispensed per 1000 patients per annum. Main findings were confirmed by secondary analyses of 256 370 isolates from 527 practices that contributed data at some point during the study period. CONCLUSION: Reducing antibiotic dispensing at general-practice level is associated with reduced local antibiotic resistance. These findings should further encourage clinicians and patients to use antibiotics conservatively.     

Primary care quality indicators for children: measuring quality in UK general practice

Background

Child health care is an important part of the UK general practice workload; in 2009 children aged <15 years accounted for 10.9% of consultations. However, only 1.2% of the UK’s Quality and Outcomes Framework pay-for-performance incentive points relate specifically to children.

Aim

To improve the quality of care provided for children and adolescents by defining a set of quality indicators that reflect evidence-based national guidelines and are feasible to audit using routine computerised clinical records.

Design and setting

Multi-step consensus methodology in UK general practice.

Method

Four-step development process: selection of priority issues (applying nominal group methodology), systematic review of National Institute for Health and Care Excellence (NICE) and Scottish Intercollegiate Guidelines Network (SIGN) clinical guidelines, translation of guideline recommendations into quality indicators, and assessment of their validity and implementation feasibility (applying consensus methodology used in selecting QOF indicators).

Results

Of the 296 national guidelines published, 48 were potentially relevant to children in primary care, but only 123 of 1863 recommendations (6.6%) met selection criteria for translation into 56 potential quality indicators. A further 13 potential indicators were articulated after review of existing quality indicators and standards. Assessment of the validity and feasibility of implementation of these 69 candidate indicators by a clinical expert group identified 35 with median scores 8 on a 9-point Likert scale. However, only seven of the 35 achieved a GRADE rating >1 (were based on more than expert opinion).

Conclusion

Producing valid primary care quality indicators for children is feasible but difficult. These indicators require piloting before wide adoption but have the potential to raise the standard of primary care for all children.     

Results of a 12-month quality-circle prescribing improvement programme for GPs

BACKGROUND: The impact of a quality-circle GP prescribing improvement programme, implemented in France in 2001-2002, was assessed by a controlled study. The study involved all 27 GPs of three semi-rural areas of Brittany, France. Practice data (overall prescribing cost and markers of prescribing efficiency) were collated in an intention-to-treat analysis, using the Mann-Whitney U test. Twenty-four GPs attended the meetings regularly. The reduction in drug expenditure exceeded the cost of the programme, although variations in size effects were observed among the settings.     

GPs' approach to insulin prescribing in older patients: a qualitative study

BACKGROUND: Evidence suggests that insulin is under-prescribed in older people. Some reasons for this include physician's concerns about potential side-effects or patients' resistance to insulin. In general, however, little is known about how GPs make decisions related to insulin prescribing in older people. AIM: To explore the process and rationale for prescribing decisions of GPs when treating older patients with type 2 diabetes. DESIGN OF STUDY: Qualitative individual interviews using a grounded theory approach. SETTING: Primary care. METHOD: A thematic analysis was conducted to identify themes that reflected factors that influence the prescribing of insulin. RESULTS: Twenty-one GPs in active practice in Ontario completed interviews. Seven factors influencing the prescribing of insulin for older patients were identified: GPs' beliefs about older people; GPs' beliefs about diabetes and its management; gauging the intensity of therapy required; need for preparation for insulin therapy; presence of support from informal or formal healthcare provider; frustration with management complexity; and GPs' experience with insulin administration. Although GPs indicated that they would prescribe insulin allowing for the above factors, there was a mismatch in intended approach to prescribing and self-reported prescribing. CONCLUSION: GPs' rationale for prescribing (or not prescribing) insulin is mediated by both practitioner-related and patient-related factors. GPs intended and actual prescribing varied depending on their assessment of each patient's situation. In order to improve prescribing for increasing numbers of older people with type 2 diabetes, more education for GPs, specialist support, and use of allied health professionals is needed.     

Online data on opening hours of general practices in England: a comparison with telephone survey data

Background

The NHS Choices website (www.nhs.uk) provides data on the opening hours of general practices in England. If the data are accurate, they could be used to examine the benefits of extended hours.

Aim

To determine whether online data on the opening times of general practices in England are accurate regarding the number of hours in which GPs provide face-to-face consultations.

Design and setting

Cross-sectional comparison of data from NHS Choices and telephone survey data reported by general practice staff, for a nationally representative sample of 320 general practices (December 2013 to September 2014).

Method

GP face-to-face consultation times were collected by telephone for each sampled practice for each day of the week. NHS Choices data on surgery times were available online. Analysis was based on differences in the number of surgery hours (accounting for breaks) and the times of the first and last consultations of the day only between the two data sources.

Results

The NHS Choices data recorded 8.8 more hours per week than the survey data on average (40.1 versus 31.2; 95% confidence interval [CI] = 7.4 to 10.3). This was largely accounted for by differences in the recording of breaks between sessions. The data were more similar when only the first and last consultation times were considered (mean difference = 1.6 hours; 95% CI = 0.9 to 2.3).

Conclusion

NHS Choices data do not accurately measure the number of hours in which GPs provide face-to-face consultations. They better record the hours between the first and last consultations of the day.     

Achievement of cholesterol targets and prescribing of higher-cost statins: a cross-sectional study in general practice

Background

There is conflicting evidence as to whether achievement of cholesterol targets at the population level is dependent on the choice and cost of statin.

Aim

To investigate the practice-level relationship between cholesterol quality indicators in patients with heart disease, stroke, and diabetes and prescribing of low-cost statins.

Design and setting

Correlations and linear regression modelling of retrospective cross-sectional practice-level data with potential explanatory variables in 7909 (96.4%) general practices in England in 2008–2009.

Method

Quality indicator data were obtained from the Information Centre and prescribing data from the NHS Business Authority. A ‘cholesterol quality indicator’ score was constructed by dividing the numbers of patients achieving the target for cholesterol control of ≤5 mmol/l in stroke, diabetes, and heart disease by the numbers on each register. A ‘low-cost statin’ ratio score was constructed by dividing the numbers of defined daily doses of simvastatin and pravastatin by the total numbers of defined daily doses of statins.

Results

Simvastatin accounted for 83.3% (standard deviation [SD] = 15.7%) of low-cost statins prescribed and atorvastatin accounted for 85.7% (SD = 14.8%) of high-cost statins prescribed. The mean cholesterol score was 73.7% (SD = 6.0%). Practices using a higher proportion of the low-cost statins were less successful in achieving cholesterol targets. An increase of 10% in the prescribing of low-cost statins was associated with a decrease of 0.46% in the cholesterol quality indicator score (95% confidence interval = –0.54% to –0.38%, P<0.001).

Conclusion

Greater use of low-cost statins was associated with a small reduction in cholesterol control.     

The UK pay-for-performance programme in primary care: estimation of population mortality reduction

Background

General practices in the UK contract with the government to receive additional payments for high-quality primary care. Little is known about the resulting impact on population health.

Aim

To estimate the potential reduction in population mortality from implementation of the pay-for-performance contract in England.

Design of study

Cross-sectional and modelling study.

Setting

Primary care in England.

Method

Twenty-five clinical quality indicators in the contract had controlled trial evidence of mortality benefit. This was combined with condition prevalence, and the differences in performance before and after contract implementation, to estimate the potential mortality reduction per indicator. Improvement was adjusted for pre-existing trends where data were available.

Results

The 2004 contract potentially reduced mortality by 11 lives per 100 000 people (lower–upper estimates 7–16) over 1 year, as performance improved from baseline to the target for full incentive payment. If all eligible patients were treated, over and above the target, 56 (29–81) lives per 100 000 might have been saved. For the 2006 contract, mortality reduction was effectively zero, because new baseline performance for a typical practice had already exceeded the target performance for full payment.

Conclusion

The contract may have delivered substantial health gain, but potential health gain was limited by performance targets for full payment being set lower than typical baseline performance. Information on both baseline performance and population health gain should inform decisions about future selection of indicators for pay-for-performance schemes, and the level of performance at which full payment is triggered.     

Correlation between prescribing quality and pharmaceutical costs in English primary care: national cross-sectional analysis

Background

Both pharmaceutical costs and quality-indicator performance vary substantially between general practices, but little is known about the relationship between prescribing costs and quality

Aim

To measure the association between prescribing quality and pharmaceutical costs among English general practices

Design and setting

Cross-sectional observational study using data from the Quality and Outcomes Framework and the Prescribing Analysis and Cost database from all 8409 general practices in England in 2005-2006

Method

Correlation between practice achievement of 26 prescribing quality indicators in eight prescribing areas and related pharmaceutical costs was examined.

Results

There was no significant association between the overall achievement of quality indicators and related pharmaceutical costs (P= 0.399). Mean achievement of quality indicators across all eight prescribing areas was 79.0% (standard deviation 4.4%). There were small positive correlations in five prescribing areas: influenza vaccination, beta blockers, angiotensin converting enzyme inhibitors, lipid lowering, and antiplatelet treatment (all P<0.001). There were small negative correlations in two prescribing areas: hypertension (P<0.001) and smoking cessation (P = 0.018).

Conclusion

Correlations between prescribing quality and pharmaceutical costs were much smallerthan expected; possible explanations forthis include a substantial variation in rates of prescribing outside evidence-based protocols, and use of expensive pharmaceuticals instead of cheaper effective alternatives. There remains considerable scope for some practices to make pharmaceutical cost savings while improving quality performance. The ratio of quality scores to related pharmaceutical costs could be developed into a performance indicator     

Implementing the role of the primary care mental health worker: a qualitative study

BACKGROUND: Primary care mental health workers are a new role recently introduced into primary care in England to help manage patients with common mental health problems. AIM: To explore the views of GPs, primary care teams and patients on the value and development of the new role of primary care mental health workers in practice. DESIGN OF STUDY: Qualitative study. SETTING: The Heart of Birmingham Primary Care Teaching Trust in the West Midlands, UK. METHOD: Thirty-seven semi-structured interviews involving seven primary care mental health workers, 21 patients and 11 focus groups involving 38 members of primary care teams were held with six teams with a worker. Two teams asked for the worker to be removed. Six practice managers also took part in the study. RESULTS: A number of different approaches were used to implement this new role. Strategies that incorporated the views of primary care trust senior management, primary care teams and workers' views appeared most successful. Rapid access to a healthcare professional at times of stress and the befriending role of the worker were also highly valued. Workers felt that their role left them professionally isolated at times. A number of workers described tension around ownership of the role. CONCLUSION: Primary care mental health workers appear to provide a range of skills valued by patients and the primary care teams and can increase patient access and choice in this area of health care. Successful implementation strategies highlighted in this study may be generalisable to other new roles in primary care.     

Association between point-of-care CRP testing and antibiotic prescribing in respiratory tract infections: a systematic review and meta-analysis of primary care studies

Background

Most patients with respiratory tract infections (RTIs) are prescribed antibiotics in general practice. However, there is little evidence that antibiotics bring any value to the treatment of most RTIs. Point-of-care C-reactive protein testing may reduce antibiotic prescribing.

Aim

To systematically review studies that have examined the association between point-of-care (POC) C-reactive protein testing and antibiotic prescribing for RTIs in general practice.

Design and setting

Systematic review and meta-analysis of randomised controlled trials and observational studies.

Method

MEDLINE^® and Embase were systematically searched to identify relevant publications. All studies that examined the association between POC C-reactive protein testing and antibiotic prescribing for patients with RTIs were included. Two authors independently screened the search results and extracted data from eligible studies. Dichotomous measures of outcomes were combined using risk ratios (RRs) with 95% confidence intervals (CIs) either by fixed or random-effect models.

Results

Thirteen studies containing 10 005 patients met the inclusion criteria. POC C-reactive protein testing was associated with a significant reduction in antibiotic prescribing at the index consultation (RR 0.75, 95% CI = 0.67 to 0.83), but was not associated with antibiotic prescribing at any time during the 28-day follow-up period (RR 0.85, 95% CI = 0.70 to 1.01) or with patient satisfaction (RR 1.07, 95% CI = 0.98 to 1.17).

Conclusion

POC C-reactive protein testing significantly reduced antibiotic prescribing at the index consultation for patients with RTIs. Further studies are needed to analyse the confounders that lead to the heterogeneity.
