Do guidelines influence practice?

Applicability of European Society of Cardiology guidelines according to gross national income

AIMS

To assess the feasibility to comply with the recommended actions of ESC guidelines on general cardiology areas in 102 countries and assess how compliance relates to the country's income level.

METHODS AND RESULTS

All recommendations from seven ESC guidelines on general cardiology areas were extracted and labelled on recommended actions. A survey was sent to all 102 ESC national and affiliated cardiac societies (NCSs). Respondents were asked to score recommended actions on their availability in clinical practice on a four-point Likert scale (fully available, mostly/often available, mostly/often unavailable, fully unavailable), and select the top three barriers perceived as being responsible for limiting their national availability. Applicability was assessed overall, per World Bank gross national income (GNI) level, and per guideline.A total of 875 guideline recommendations on general cardiology was extracted. Responses were received from 64 of 102 (62.7%) NCSs. On average, 71·6% [95% confidence interval (CI): 68.6-74.6] of the actions were fully available, 9.9% (95% CI: 8.7-11.1) mostly/often available, 6.7% (95% CI: 5.4-8.0) mostly/often unavailable, and 11·8% (95% CI: 9.5-14.1) fully unavailable. In low-income countries (LICs), substantially more actions were fully unavailable [29·4% (95% CI: 22.6-36.3)] compared with high-income countries [HICs, countries 2.4% (95% CI: 1.2-3.7); P < 0.05]. Nevertheless, a proportion of actions with the lowest availability scores were often fully or mostly unavailable independent of GNIs. Actions were most often not available due to lack of reimbursement and other financial barriers.

CONCLUSION

Local implementation of ESC guidelines on general cardiology is high in HICs and low in LICs , being inversely correlated with country gross national incomes.

Structural quality of labor and delivery care in government hospitals of Ethiopia: a descriptive analysis

Background

Ethiopia has low skilled birth attendance rates coupled with low quality of care within health facilities contributing to one of the highest maternal mortality rates in Sub-Saharan Africa, at 412 deaths per 100,000 live births. There is lack of evidence on the readiness of health facilities to deliver quality labor and delivery (L&D) care. This paper describes the structural quality of routine L&D care in government hospitals of Ethiopia.

Methods

A facility-based cross-sectional study design, involving census of all government hospitals in Southern Nations Nationalities and People’s Region (SNNPR) (N = 20) was conducted in November 2016 through facility audit using a structured checklist. Data collectors verified the availability and functioning of the required items through observation and interview with the heads of labor and delivery case team. An overall mean score of structural quality was calculated considering domain scores such as general infrastructure, human resource and essential drugs, supplies, equipment and laboratory services. Summary statistics such as proportion, mean and standard deviation were computed to describe the degree of adherence of the hospitals to the standards related to structural quality of routine labor and delivery care.

Results

One third of hospitals had low readiness to provide quality routine L&D care, with only two approaching near fulfilment of all the standards. Hospitals had fulfilled 68.2% of the standards for the structural aspects of quality of L&D care. Of the facility audit criteria, the availability of essential equipment and supplies for infection prevention scored the highest (88.8%), followed by safety, comfort and woman friendliness of the environment (76.4%). Availability skilled health professionals and quality management practices scored 72.5% each, while availability of the required items of general infrastructure was 64.6%. The two critical domains with the lowest score were availability of essential drugs, supplies and equipment (52.2%); and laboratory services and safe blood supply (50%).

Conclusion

Substantial capacity gaps were observed in the hospitals challenging the provision of quality routine L&D care services, with only two thirds of required resources available. The largest gaps were in laboratory services and safe blood, and essential drugs, supplies and equipment. The results suggest the need to ensure that all public hospitals in SNNPR meet the required structure to enable the provision of quality routine L&D care with emphases on the identified gaps.

Socio-Ecological Systems Analysis and Health System Readiness in Responding to Dengue Epidemics in Ilala and Kinondoni Districts, Tanzania

Introduction

Since 2010, Tanzania has been experiencing frequent outbreaks of dengue. The objectives of this study were to carry out a socio-ecological systems (SES) analysis to identify risk factors and interventions and assess the readiness of the district in the prevention and control of dengue.

Methods

The study utilized a cross-sectional purposive selection of key stakeholders responsible for disease surveillance and response in human and animal sectors in Ilala and Kinondoni districts in Tanzania. A SES framework was used to identify drivers and construct perceived thematic causal explanations of the dengue outbreaks in the study districts. A mapping exercise was carried out to analyse the performance of the disease surveillance system at district and facility levels. A semi-structured questionnaire was used to assess the districts’ readiness in the response to dengue outbreak.

Results

The two districts were characterized by both urban and peri-urban ecosystems, with a mixture of planned and unplanned settlements which support breeding and proliferation of Aedes mosquitoes. The results indicate inadequate levels of readiness in the management and control of dengue outbreaks, in terms of clinical competence, diagnostic capacities, surveillance system and control/prevention measures. Mosquito breeding sites, especially discarded automobile tyres, were reported to be scattered in the districts. Constraining factors in implementing disease surveillance included both intrapersonal and interpersonal factors, lack of case management guidelines, difficult language used in standard case definitions, inadequate laboratory capacity, lack of appropriate rapid response teams, inadequate knowledge on outbreak investigation and inadequate capacities in data management.

Conclusion

The two districts had limited readiness in the management and control of dengue, in terms of clinical competence, diagnostic capacities, surveillance system and prevention and control measures. These challenges require the immediate attention by the authorities, as they compromise the effectiveness of the national strategy for community health support.

Understanding providers' attitudes and key concerns toward incorporating CVD risk prediction into clinical practice: a qualitative study

Background

Although risk prediction has become an integral part of clinical practice guidelines for cardiovascular disease (CVD) prevention, multiple studies have shown that patients’ risk still plays almost no role in clinical decision-making. Because little is known about why this is so, we sought to understand providers’ views on the opportunities, barriers, and facilitators of incorporating risk prediction to guide their use of cardiovascular preventive medicines.

Methods

We conducted semi-structured interviews with primary care providers (n = 33) at VA facilities in the Midwest. Facilities were chosen using a maximum variation approach according to their geography, size, proportion of MD to non-MD providers, and percentage of full-time providers. Providers included MD/DO physicians, physician assistants, nurse practitioners, and clinical pharmacists. Providers were asked about their reaction to a hypothetical situation in which the VA would introduce a risk prediction-based approach to CVD treatment. We conducted matrix and content analysis to identify providers’ reactions to risk prediction, reasons for their reaction, and exemplar quotes.

Results

Most providers were classified as Enthusiastic (n = 14) or Cautious Adopters (n = 15), with only a few Non-Adopters (n = 4). Providers described four key concerns toward adopting risk prediction. Their primary concern was that risk prediction is not always compatible with a “whole patient” approach to patient care. Other concerns included questions about the validity of the proposed risk prediction model, potential workflow burdens, and whether risk prediction adds value to existing clinical practice. Enthusiastic, Cautious, and Non-Adopters all expressed both doubts about and support for risk prediction categorizable in the above four key areas of concern.

Conclusions

Providers were generally supportive of adopting risk prediction into CVD prevention, but many had misgivings, which included concerns about impact on workflow, validity of predictive models, the value of making this change, and possible negative effects on providers’ ability to address the whole patient. These concerns have likely contributed to the slow introduction of risk prediction into clinical practice. These concerns will need to be addressed for risk prediction, and other approaches relying on “big data” including machine learning and artificial intelligence, to have a meaningful role in clinical practice.

Secondary prevention and cardiovascular care across Europe: A survey of European Society of Cardiology members’ views

Introduction:

Secondary prevention of cardiovascular disease is a significant clinical challenge and despite European Society of Cardiology (ESC) Guidelines, evidence confirms sub-optimal patient care.

Aim:

The aim of this study was to evaluate ESC members’ opinions on the current provision of cardiovascular prevention and rehabilitation services across Europe and explore barriers to guideline implementation.

Method:

Electronic surveys using a secure web link were sent to members of the ESC in eight purposively selected ESC affiliated countries.

Results:

A total of 479 professionals completed the survey, of whom 67% were cardiologists, 8.6% general physicians, 8.2% nurses and 16.2% other healthcare professionals. Respondents were predominantly (91%) practising clinicians, generally highly motivated regarding cardiovascular disease prevention, but most reported that secondary prevention in their country was sub-optimal. The main barriers to prevention were lack of available cardiac rehabilitation programmes and long-term follow-up, patients’ disease perception and professional attitudes towards prevention. While knowledge of the prevention guidelines was generally good, practices such as motivational counselling and better educational tools were called for to promote exercise, smoking cessation and for nutritional aspects.

Conclusions:

The provision of services focusing on the secondary prevention of cardiovascular disease varies greatly across Europe. Furthermore, despite ESC Guidelines and a strong evidence base supporting the efficacy of secondary prevention, the infrastructure and co-ordination of such care is lacking. In addition patient motivation is considered poor and some professionals remain unconvinced about the merits of prevention. The disappointing results outlined in this survey emphasise that improved tools are urgently required to educate both patients and professionals and confirm the priority of cardiovascular prevention internationally.

Choosing Wisely® in Preventive Medicine: The American College of Preventive Medicine's Top 5 List of Recommendations

The Choosing Wisely(®) initiative is a national campaign led by the American Board of Internal Medicine Foundation, focused on quality improvement and advancing a dialogue on avoiding wasteful or unnecessary medical tests, procedures, and treatments. The American College of Preventive Medicine (ACPM) Prevention Practice Committee is an active participant in the Choosing Wisely project. The committee created the ACPM Choosing Wisely Task Force to lead the development of ACPM's recommendations with the intention of facilitating wise decisions about the appropriate use of preventive care. After utilizing an iterative process that involved reviewing evidence-based literature, the ACPM Choosing Wisely Task Force developed five recommendations targeted toward overused services within the field of preventive medicine. These include: (1) don't take a multivitamin, vitamin E, or beta carotene to prevent cardiovascular disease or cancer; (2) don't routinely perform prostate-specific antigen-based screening for prostate cancer; (3) don't use whole-body scans for early tumor detection in asymptomatic patients; (4) don't use expensive medications when an equally effective and lower-cost medication is available; and (5) don't perform screening for cervical cancer in low-risk women aged 65 years or older and in women who have had a total hysterectomy for benign disease. The Task Force also reviewed some of the barriers to implementing these recommendations, taking into account the interplay between system and environmental characteristics, and identified specific strategies necessary for timely utilization of these recommendations.

Impact of drug policy on regional trends in ezetimibe use

BACKGROUND

Ezetimibe use has steadily increased in Canada during the past decade even in the absence of evidence demonstrating a beneficial effect on clinical outcomes. Among the 4 most populated provinces in Canada, there is a gradient in the restrictiveness of ezetimibe in public-funded formularies (most to least strict: British Columbia, Alberta, Quebec, and Ontario). The effect of formulary policy on the use of ezetimibe over time is unknown.

METHODS AND RESULTS

We conducted a population-level cohort study using Intercontinental Marketing Services Health Canada's data from June 2003 to December 2012 to examine ezetimibe use in these 4 provinces to better understand the association between use and formulary restrictiveness. We found regional variations in the patterns of ezetimibe use. From June 2003 to December 2012, British Columbia (most restrictive) had the lowest monthly increasing rate from $261 to $21 926 ($190/100 000 population/mo), whereas Ontario (least restrictive) had the most rapid monthly increase from $223 to $74 030 ($ 647/100 000 population/mo), and Quebec from $130 to $59 690 ($522/100 000 population/mo) and Alberta from $356 to $ 37 604 ($327/100 000 population/mo) were intermediate (P<0.001).

CONCLUSIONS

Ezetimibe use remains common, increasing during the past decade. Use steadily increased in provinces with the most lenient formularies. In contrast, use was lower, plateauing since 2008 in British Columbia and Alberta, which have more restrictive formularies. The gradient in ezetimibe use was related to variability in restrictiveness of the provincial formularies, illustrating the potential of a policy response gradient that may be used to more effectively manage medication use.

Do guidelines influence the implementation of health programs?--Uganda's experience

Background

A guideline contains processes and procedures intended to guide health service delivery. However, the presence of guidelines may not guarantee their implementation, which may be a result of weaknesses in the development process. This study was undertaken to describe the processes of developing health planning, services management, and clinical guidelines within the health sector in Uganda, with the goal of understanding how these processes facilitate or abate the utility of guidelines.

Methods

Qualitative and quantitative research methods were used to collect and analyze data. Data collection was undertaken at the levels of the central Ministry of Health, the district, and service delivery. Qualitative methods included review of documents, observations, and key informant interviews, as well as quantitative aspects included counting guidelines. Quantitative data were analyzed with Microsoft Excel, and qualitative data were analyzed using deductive content thematic analysis.

Results

There were 137 guidelines in the health sector, with programs related to Millennium Development Goals having the highest number (n = 83). The impetus for guideline development was stated in 78% of cases. Several guidelines duplicated content, and some conflicted with each other. The level of consultation varied, and some guidelines did not consider government-wide policies and circumstances at the service delivery level. Booklets were the main format of presentation, which was not tailored to the service delivery level. There was no framework for systematic dissemination, and target users were defined broadly in most cases. Over 60% of guidelines available at the central level were not available at the service delivery level, but there were good examples in isolated cases. There was no framework for systematic monitoring of use, evaluation, and review of guidelines. Suboptimal performance of the supervision framework that would encourage the use of guidelines, assess their utilization, and provide feedback was noted.

Conclusions

Guideline effectiveness is compromised by the development process. To ensure the production of high-quality guidelines, efforts must be employed at the country and regional levels. The regional level can facilitate pooling resources and expertise in knowledge generation, methodology development, guideline repositories, and capacity building. Countries should establish and enforce systems and guidance on guideline development.

Is blood thicker than water? Peer effects in stent utilization among Floridian cardiologists

Variations in physician practice are pervasive and costly, and may be harmful. The objective of much policy in the West is to increase the interconnectedness of physicians, furthering the transfer of information and thus reducing variation. This study tests whether physicians are influenced by the practice of peers, or if propensity, mere context or sorting of like-minded physicians better explain similarities and differences in practice. We study US cardiologists who place coronary stents into patients with blocked arteries around the heart. Organized in locally competing physician groups and also as solo practitioners, they see patients in offices, but insert the stents at a shared production facility - the cath lab. We examine their use of the popular drug-eluting coronary stents between their launch and rapid adoption in early 2003, and through the period of late 2006 in which private and public reports of serious late side-effects eventually led to reductions in use. Our analyses use administrative claims data on nearly 1000 cardiologists and their patients in Florida, USA, merged with Florida physician licensure data. Collectively these physicians used these stents nearly a quarter of a million times in the 4 year period reviewed. Pooled and panel linear regressions for device utilization by a physicians are estimated using measures of peer utilization, physician characteristics and controls for unobservable physician characteristics, common shocks and selection effects. We find strong evidence for intra-group but against inter-group practice spillovers. Even when sharing the same lab, competing cardiologists did not appear to correlate practices. Our results are consistent with a view that policies aimed at increasing the interconnectedness of physicians must first consider the organizational barriers and competitive forces that can stymie knowledge transfer even among physicians working closely together.

Nursing care practices following a percutaneous coronary intervention: results of a survey of Australian and New Zealand cardiovascular nurses

BACKGROUND

Although there is high-level evidence to guide optimal medical care for percutaneous coronary interventions, there are less explicit guidelines to support nurses in providing care.

AIM

This study describes the practice standards and priorities of care of cardiovascular nurses in Australia and New Zealand.

METHOD

Item generation for the survey was informed by an integrative literature review and existing clinical guidelines. A 116-item Web-based survey was administered to cardiovascular nurses, via electronic mail lists of professional cardiovascular nursing organizations, using a secure online data collection system.

RESULTS

Data were collected from March 2008 to March 2009. A total of 148 respondents attempted the survey, with 110 (74.3%) completing all items. All respondents were registered nurses with an average of 12.3 (SD, 7.61) years of clinical experience in the cardiovascular setting. A range of practice patterns was evident in ambulation time after percutaneous coronary intervention, methods of sheath removal, pain relief, and patient positioning. Respondents consistently rated psychosocial care a lower priority than other tasks and also identified a knowledge deficit in this area.

CONCLUSION

This survey identified diversity of practice patterns and a range of educational needs. Increasing evidence to support evidence-based practice and guideline development is necessary to promote high-quality care and improved patient outcomes.

Impact of restrictive prescription plans on heart failure medication use

BACKGROUND

Prescription plans frequently use restrictive strategies to control drug expenditures. Increased restrictions may reduce access to evidence-based therapy among patients with chronic disease. We sought to evaluate the impact of increased restrictions on medication use among heart failure (HF) patients.

METHODS AND RESULTS

We conducted a population-based cohort study of administrative data from 3 Canadian provinces. During 1998 to 2001, Quebec (QC) had a minimally restrictive plan, whereas Ontario (ON) and British Columbia (BC) had more restrictive prescription plans. We evaluated drug use at 30 days of discharge stratified by prescription plan. Provincial rates of filled prescriptions for HF drugs in QC, ON, and BC were 62%, 58%, and 47% for angiotensin-converting enzyme inhibitors; 34%, 22%, and 16% for beta-blockers; 9%, 5%, and 3% for angiotensin receptor blockers; and 79%, 76%, and 62% for loop diuretics, respectively. In multivariate analyses, patients residing in provinces with restrictive plans were less likely to be prescribed drugs that were restricted, such as beta-blockers (odds ratio, 0.53; 95% CI, 0.46 to 0.60; 0.36, 0.29 to 0.44, for ON and BC, respectively) and angiotensin receptor blockers (0.50, 0.45 to 0.56; 0.38, 0.32 to 0.46, for ON and BC, respectively), than drugs with no restrictions, such as loop diuretics (0.81, 0.74 to 0.88; 0.40, 0.36 to 0.45, for ON and BC, respectively) and angiotensin-converting enzyme inhibitors (0.80, 0.75 to 0.86; 0.47, 0.43 to 0.52, for ON and BC, respectively).

CONCLUSIONS

Among HF patients, residing in a province with a more restrictive prescription plan may be associated with lower use of restricted HF medications over and above the expected regional differences in HF drug use across provinces.

Comparison of presenting features, diagnostic tools, hospital outcomes, and quality of care indicators in older (>65 years) to younger, men to women, and diabetics to nondiabetics with acute chest pain triaged in the emergency department

In a total of 4,843 consecutive patients admitted to an emergency department (ED) with acute chest pain over a 1-year period, presenting features, diagnostic tools, hospital outcomes, and quality-of-care indicators were compared between older (n = 1,781) and younger (n = 3,062) patients, men (n = 3,095) and women (n = 1,748), and diabetics (n = 856) and nondiabetics (n = 3,987). The results showed that after critical pathway implementation, there was an increase in the use of evidence-based treatment strategies in the ED and improved outcomes in older patients, women, and diabetics, with no more differences in the length of ED stay, diagnostic accuracy for myocardial infarction in the ED, door-to-thrombolysis time, and door-to-balloon time compared with younger patients, men, and nondiabetics.
