What is the future of primary care research? Probably fairly bright, if we may believe the historical development

General practice-related MeSH terms in main journals: a bibliometric analysis from 2011 to 2021

BACKGROUND

There are various Medical Subject Headings (MeSH) terms used to index general practice research, without consistency.

AIM

To understand how general practice-related research is indexed in the main general practice journals between 2011 and 2021, and to analyse the factors that influenced the choice of the general practice-related MeSH.

DESIGN AND SETTING

This was a quantitative bibliometric study conducted on MEDLINE.

METHOD

MeSH were selected according to the international definition of General Practice/Family Medicine: 'General Practice', 'Primary Health Care', 'Family Practice', 'General Practitioners', 'Physicians, Primary Care', and 'Physicians, Family'. Their use was studied from 2011 to 2021 on MEDLINE, reviewing the 20 general practice journals with the highest impact factors. A descriptive and analytical approach was used; the association of the country, journal, and year with the choice of general practice-related MeSH terms was analysed.

RESULTS

A total of 8514 of 150 286 articles (5.7%) were using one of the general practice-related MeSH terms. The most used were 'Primary Health Care' (4648/9984, 46.6%) and 'General Practice' (2841/9984, 28.5%). A total of 80.0% (6172/7723) of the articles were related to the UK or US and 71.0% (6055/8514) of the articles came from four journals (BJGP, BMJ, Journal of General Internal Medicine, and Annals of Family Medicine). Two main country clusters emerged from the use of general practice-related MeSH: a British cluster mainly using 'General Practice' and an American cluster using 'Primary Health Care'. The journals also mainly differed in their used of these two MeSH terms.

CONCLUSION

Important variations in the indexation of general practice research were found. Researchers should consider combining 'Primary Health Care' and 'General Practice' in their PubMed searches to access all the general practice research, regardless of their country of origin.

Promoting the creation of R&D intentions in primary healthcare measured by a validated instrument

BACKGROUND

Primary healthcare has a long and successful patient care history in Sweden. Nevertheless, a research-oriented attitude has been more or less absent in this context. In society today, access to information has significantly influenced the nature of patients' demand for up-to-date healthcare. A prerequisite for this new demand is health professionals who are interested in novel ways of thinking and view a change of work practices as necessary. One way to achieve this goal is by means of strategic communication, which is a relatively new interdisciplinary field. The aim of this study was to analyse the role of strategic communication in the creation of intentions in Research and Development (R&D) among primary healthcare staff as measured by a validated instrument.

METHODS

An intervention study on staff was performed. A 15-item questionnaire was validated and implemented. All primary healthcare staff from the southwestern Swedish province of Halland were included. In total, 846 employees (70%) agreed to participate in the measurements. After 12 years, 352 individuals who had participated in the intervention and remained in the organisation were identified and followed up. The intervention comprised established communication channels. The measurements were performed after 7 and 12 years. A questionnaire was designed for this purpose. The questions were validated by a factor analysis, and the degree of reliability was measured with Cronbach's alpha coefficient. χ² and Fisher's exact tests were used as statistical tests in comparisons.

RESULTS

Factor analysis identified five pure factors (most Cronbach's alpha > 0.70). Strategic communication contributed to a significant improvement in the staff members' interest in R&D and willingness to change in both the short (P < 0.05) and long (P < 0.05) term. The positive attitude was stable over time.

CONCLUSIONS

Strategic communication seems to be a significant tool for creating a stable positive attitude towards R&D in the primary healthcare context. The creation of a positive attitude towards a scientific approach is a relevant finding that deserves special attention in a context as complex as healthcare. Using a validated instrument seems to contribute to pure results in this case.

Development of Primary Care Research in North America, Europe, and Australia From 1974 to 2017

Research is a necessity for high-quality medicine. We used the MEDLINE database to conduct a bibliometric analysis of research output with respect to primary care by 21 countries. For the period 1974 to 2017, the United States and the United Kingdom stood out in terms of publication volume, and the UK, Canada, and Australia had the greatest percentage of publications in primary care. As of 2017, publications in primary care represented a small proportion of total publications. The countries with the greatest publication productivity possess factors that should be considered with respect to strengthening research in primary care.

Creating research and development awareness among dental care professionals by use of strategic communication: a 12-year intervention study

Background

Despite the availability of contemporary research advances, only a limited fraction is implemented into dental practice. One possible way to facilitate this process is to stimulate the research and development (R&D) awareness and interest with aid of strategic communication.

Methods

The aim of the study was to analyse the role of a strategic communication in R&D awareness and interest among dental care professionals (DCP) over a 12-year period. A second aim was to compare the findings with those from primary care professionals (PCP). The project had a prospective design and the intervention was conducted through established oral, written and digital channels. The outcome was captured by two validated questionnaires submitted after 7 and 12 years, respectively. An additional Questionnaire file shows the details [see Additional file 1]. The material consisted of 599 health care professionals (205 DCP; 394 PCP) that responded to the first questionnaire and 526 individuals (195 DCP; 331 PCP) who responded to the second. All were employed by the primary care organization of Region Halland located in southwest of Sweden. The majority were women (≥ 85%) and the mean age at the first questionnaire was 49 years (SD 8.5). Longitudinal analyses were applied to those individuals that responded to both surveys after 7 and 12 years (n = 248). Comparisons between DCP’s and PCP’s were processed with Chi-square and Fischer’s exact tests.

Results

Strategic communication contributed to increase the R&D awareness and interest among the dental personnel. The created interest was reported stronger among the DCP when compared with PCP at both surveys (p < 0.05). The longitudinal findings confirmed a long-term interest among the DCP’s. Direct and indirect communication facilitated R&D interest in both groups. The most powerful channels were the written “Research bulletin” and peer inspiration.

Conclusion

Strategic communication can be employed as a scientific tool that may contribute to the creation of a long-term R&D awareness and interest among dental care professionals.

New Zealand needs a Practice Based Research Network

ABSTRACT Practice Based Research Networks (PBRNs) are groups of general practices collaborating to produce research. Contemporary New Zealand health information technology systems are ideal for electronic data extraction for PBRN research. Stakeholders have a valuable, but typically underutilised, part to play in research. Development of an e-participation platform will facilitate stakeholder engagement. New Zealand is in a unique position to create an innovative, low cost, stakeholder-engaged PBRN. This type of PBRN would offer unparalleled research opportunities, and would strengthen New Zealand’s general practice research capacity. The more research information we have based on our New Zealand population, the more appropriate care we can provide. Establishing a stakeholder-engaged PBRN in New Zealand will promote and support transformational change within our health system. In June 2015 I had the privilege of attending the annual Practice Based Research Network (PBRN) Conference held in Bethesda, near Washington D.C. The conference is hosted by the North American Primary Care Research Group and the United States (US) Agency for Healthcare Research and Quality. In this article I draw on the knowledge I gained at that conference and discuss its translation to New Zealand.

Prescription of antibiotics and anxiolytics/hypnotics to asthmatic patients in general practice: a cross-sectional study based on French and Italian prescribing data

Background

Asthma is often poorly controlled and guidelines are often inadequately followed in medical practice. In particular, the prescription of non-asthma-specific drugs can affect the quality of care. The goal of this study was to measure the frequency of the prescription of antibiotics and anxiolytics/hypnotics to asthmatic patients and to look for associations between sex or age and the prescription of these drugs.

Methods

A cross-sectional study was conducted using computerised medical records from French and Italian general practitioners’ networks. Patients were selected according to criteria adapted from the HEDIS (Healthcare Effectiveness Data and Information Set) criteria. The outcome measure was the number of antibiotics or anxiolytics/hypnotics prescriptions per patient in 1 year. Parallel multivariate models were developed.

Results

The final sample included 3,093 French patients (mean age 27.6 years, 49.7% women) and 3,872 Italian patients (mean age 29.1 years, 48.7% women). In the univariate analysis, the French patients were prescribed fewer antibiotics than the Italian patients (37.1% vs. 42.2%, p < 0.00001) but more anxiolytics/hypnotics (17.8% vs. 6.9%, p < 0.0001). In the multivariate models, the female patients were more likely to receive antibiotics (odds ratio: 1.5 [1.3–1.7]) and anxiolytics/hypnotics (odds ratio: 1.8 [1.5–2.1]).

Conclusions

The prescription of antibiotics and anxiolytics/hypnotics to asthmatic patients is frequent, especially in women. Asthma guidelines should address this issue by referring to other guidelines covering the prescription of non-asthma-specific drugs, and alternative non-pharmacological interventions should be considered.

Defining dimensions of research readiness: a conceptual model for primary care research networks

BACKGROUND

Recruitment to research studies in primary care is challenging despite widespread implementation of electronic patient record (EPR) systems which potentially make it easier to identify eligible cases.

METHODS

Literature review and applying the learning from a European research readiness assessment tool, the TRANSFoRm International Research Readiness instrument (TIRRE), to the context of the English NHS in order to develop a model to assess a practice's research readiness.

RESULTS

Seven dimensions of research readiness were identified: (1) Data readiness: Is there good data quality in EPR systems; (2) Record readiness: Are EPR data able to identify eligible cases and other study data; (3) Organisational readiness: Are the health system and socio-cultural environment supportive; (4) Governance readiness: Does the study meet legal and local health system regulatory compliance; (5) Study-specific readiness; (6) Business process readiness: Are business processes tilted in favour of participation: including capacity and capability to take on extra work, financial incentives as well as intangibles such as social and intellectual capital; (7) Patient readiness: Are systems in place to recruit patients and obtain informed consent?

CONCLUSIONS

The model might enable the development of interventions to increase participation in primary care-based research and become a tool to measure the progress of practice networks towards the most advanced state of readiness.

Creating an interest in research and development as a means of reducing the gap between theory and practice in primary care: an interventional study based on strategic communication

Today, healthcare professionals are faced with the challenge of implementing research results in an optimal way. It is therefore important to create a climate that is conducive to research and development (R&D). For this reason, new strategies are required to enhance healthcare professionals’ interest in innovative thinking and R&D. Strategic communication with roots in sociology, psychology and political science was employed as a means of achieving long-term behavioural change. The aim of this study was to describe, follow up and evaluate a primary care intervention based on strategic communication intended to increase healthcare professionals’ interest in R&D over time. An interventional cohort study comprising all staff members (N = 1276) in a Swedish primary care area was initiated in 1997 and continued for 12 years. The intention to engage in R&D was measured on two occasions; at 7 and 12 years. Both descriptive statistics and bivariate analyses were employed. The results demonstrated that the positive attitude to R&D increased over time, representing a first step towards new thinking and willingness to change work practices for the benefit of the patient. Strategic communication has not been previously employed as a scientific tool to create a long-term interest in R&D within primary care.

Towards efficient use of research resources: a nationwide database of ongoing primary care research projects in the Netherlands

PURPOSE. Although in the last decades primary care research has evolved with great success, there is a growing need to prioritize the topics given the limited resources available. Therefore, we constructed a nationwide database of ongoing primary care research projects in the Netherlands, and we assessed if the distribution of research topics matched with primary care practice.

METHODS

We conducted a survey among the main primary care research centres in the Netherlands and gathered details of all ongoing primary care research projects. We classified the projects according to research topic, relation to professional guidelines and knowledge deficits, collaborative partners and funding source. Subsequently, we compared the frequency distribution of clinical topics of research projects to the prevalence of problems in primary care practice.

RESULTS

We identified 296 ongoing primary care research projects from 11 research centres. Most projects were designed as randomized controlled trial (35%) or observational cohort (34%), and government funded mostly (60%). Thematically, most research projects addressed chronic diseases, mainly cardiovascular risk management (8%), depressive disorders (8%) and diabetes mellitus (7%). One-fifth of the projects was related to defined knowledge deficits in primary care guidelines. From a clinical primary care perspective, research projects on dermatological problems were significantly underrepresented (P = 0.01).

CONCLUSIONS

This survey of ongoing projects demonstrates that primary care research has a firm basis in the Netherlands, with a strong focus on chronic disease. The fit with primary care practice can improve, and future research should address knowledge deficits in professional guidelines more.

The contribution of Primary Health Care Research, Evaluation and Development-supported research to primary health care policy and practice

The importance of primary health care (PHC) research is well understood yet conducting this research can be challenging. Barriers include a lack of funding, support and opportunity. In 2000 the Australian government introduced the Primary Health Care Research, Evaluation and Development (PHCRED) Strategy to address the gap in high-quality research. One component of the strategy, the Research Capacity Building Initiative, provided funding to university departments of general practice and rural health, allowing them to expand their pool of researchers and produce more research relevant to policy and practice. This study investigates the impact of phase two of the PHCRED Strategy by analysing peer-reviewed publications from PHCRED-supported departments. Research output was recorded from 2006 to 2010 incorporating 661 publications in 212 journals. Rural departments often had fewer resources than urban departments yet demonstrated steady research contributions focusing on issues relevant to their community. Since its inception the PHCRED Strategy has enabled development of research capacity and contributed to the body of PHC knowledge. While PHC is a diverse field, reflected in the publications produced, the themes underlying much of this work were representative of current health reform and the priority areas and building blocks of the National PHC Strategy.

A bibliometric analysis of childhood immunization research productivity in Africa since the onset of the Expanded Program on Immunization in 1974

BACKGROUND

The implementation of strategic immunization plans whose development is informed by available locally-relevant research evidence should improve immunization coverage and prevent disease, disability and death in Africa. In general, health research helps to answer questions, generate the evidence required to guide policy and identify new tools. However, factors that influence the publication of immunization research in Africa are not known. We, therefore, undertook this study to fill this research gap by providing insights into factors associated with childhood immunization research productivity on the continent. We postulated that research productivity influences immunization coverage.

METHODS

We conducted a bibliometric analysis of childhood immunization research output from Africa, using research articles indexed in PubMed as a surrogate for total research productivity. We used zero-truncated negative binomial regression models to explore the factors associated with research productivity.

RESULTS

We identified 1,641 articles on childhood immunization indexed in PubMed between 1974 and 2010 with authors from Africa, which represent only 8.9% of the global output. Five countries (South Africa, Nigeria, The Gambia, Egypt and Kenya) contributed 48% of the articles. After controlling for population and gross domestic product, The Gambia, Guinea-Bissau and Sao Tome and Principe were the most productive countries. In univariable analyses, the country's gross domestic product, total health expenditure, private health expenditure, and research and development expenditure had a significant positive association with increased research productivity. Immunization coverage, adult literacy rate, human development index and physician density had no significant association. In the multivarable model, only private health expenditure maintained significant statistical association with the number of immunization articles.

CONCLUSIONS

Immunization research productivity in Africa is highly skewed, with private health expenditure having a significant positive association. However, the current contribution of authors from Africa to global childhood immunization research output is minimal. The lack of association between research productivity and immunization coverage may be an indication of lack of interactive communication between health decision-makers, program managers and researchers; to ensure that immunization policies and plans are always informed by the best available evidence.

General practice-based clinical trials in Germany - a problem analysis

BACKGROUND

In Germany, clinical trials and comparative effectiveness studies in primary care are still very rare, while their usefulness has been recognised in many other countries. A network of researchers from German academic general practice has explored the reasons for this discrepancy.

METHODS

Based on a comprehensive literature review and expert group discussions, problem analyses as well as structural and procedural prerequisites for a better implementation of clinical trials in German primary care are presented.

RESULTS

In Germany, basic biomedical science and technology is more reputed than clinical or health services research. Clinical trials are funded by industry or a single national programme, which is highly competitive, specialist-dominated, exclusive of pilot studies, and usually favours innovation rather than comparative effectiveness studies. Academic general practice is still not fully implemented, and existing departments are small. Most general practitioners (GPs) work in a market-based, competitive setting of small private practices, with a high case load. They have no protected time or funding for research, and mostly no research training or experience. Good Clinical Practice (GCP) training is compulsory for participation in clinical trials. The group defined three work packages to be addressed regarding clinical trials in German general practice: (1) problem analysis, and definition of (2) structural prerequisites and (3) procedural prerequisites. Structural prerequisites comprise specific support facilities for general practice-based research networks that could provide practices with a point of contact. Procedural prerequisites consist, for example, of a summary of specific relevant key measures, for example on a web platform. The platform should contain standard operating procedures (SOPs), templates, checklists and other supporting materials for researchers.

CONCLUSION

All in all, our problem analyses revealed that a substantial number of barriers contribute to the low implementation of clinical research in German general practice. Some issues are deeply rooted in Germany's market-based healthcare and academic systems and traditions. However, new developments may facilitate change: recent developments in the German research landscape are encouraging.

[Bibliometric analysis of International Scientific production on primary care]

OBJECTIVE

To present an international view of the scientific production in the field of primary care in the period 1985-2004.

DESIGN

Retrospective, observational study. Bibliometric analysis.

LOCATION

Medline database. WebSPIRS access through version 4.3. We analysed two periods: 2000-2004 (cross-sectional) and 1985-2004 (developmental). Search based on "MeSH Major" with descriptors: Primary Care or Primary Health Care, Family Practice, Family Physicians, Nurse Practitioners, and Entry Terms associated with these.

KEY MEASURES

We analysed the bibliometric indicators of production, circulation, dispersion, and visibility.

RESULTS

In 2000-2004, published 20911 articles were published, 0.73% of total production. There was a growth rate (1985-2004) of 221%, which was 2.4 times more than average. Transience rate was 83.17%. The English language is predominant (88.81%) over 34 languages, with Spanish being the next (2.6%). Sixteen countries produce 95.67% of the articles. Spain occupies the 7th place. Universities (52%) are the most productive institutions. There are 1074 different journals with the 10 most productive being: Br J Gen Pract, Adv Nurse Pract, Aust Fam Physician, Fam Pract, Fam Med, BMJ, Aten Primary Health Serv J, Can Fam Physician, J Fam Pract. The proportion of trials (5.43%) in PC is similar to other disciplines and has increased by 453% (1985-2004).

CONCLUSIONS

The production of Primary care is about 1% of the total scientific output, with a noticeable and higher than average growth over 20 years. The proportion of clinical trials is similar to other disciplines. Although Anglo-Saxon countries and journals are the highest producers, Spain and the journal Aten Primaria is among those highlighted.

Themes and methods of research presented at European General Practice Research Network conferences

BACKGROUND

The World Organization of Family Doctors (Wonca) defined core characteristics of general practice and general practitioners' competencies. It is unclear to which extent research has addressed these issues so far.

OBJECTIVE

To determine themes and research methods of general practice research as reflected by presentations at the European General Practice Research Network (EGPRN) meetings.

METHODS

Descriptive and retrospective study. All abstracts presented at each of the 14 EGPRN conferences between June 2001 and October 2007 were analysed for content and study design/methodology. Categories for content were developed inductively; a predefined hierarchical scheme was used for study designs.

RESULTS

A total of N=614 abstracts were classified. The main research topics were related to GP/health service issues (n=232), clinical (n=148) and patient-related themes (n=118). Original data (n=558) were mainly derived from cross-sectional designs (38.7%). Intervention studies (11.0%), longitudinal designs including case-control and cohort studies (13.3%) as well as instrumental research (2.2%) were less common. More than one-fourth of all original studies were qualitative studies (27.6%). Stratified analysis revealed that cross-sectional designs were less frequent in the second half of conferences. Analysis by country showed that, in contrast to different quantitative designs, the proportion of qualitative studies was comparable.

CONCLUSIONS

To test effectiveness of diagnostic and therapeutic interventions under primary care conditions, a higher proportion of experimental studies would be preferable. This could increase the acceptance of general practitioners' specific approaches and provide clear guidance on approaches and procedures, especially in health care systems not predominantly based on primary care.

Survey among 78 studies showed that Lasagna's law holds in Dutch primary care research

OBJECTIVE

Research in general practice has grown considerably over the past decades, but many projects face problems when recruiting patients. Lasagna's Law states that medical investigators overestimate the number of patients available for a research study. We aimed to assess factors related to success or failure of recruitment in general practice research.

STUDY DESIGN AND SETTING

Survey among investigators involved in primary care research in The Netherlands. Face-to-face interviews were held with investigators of 78 projects, assessing study design and fieldwork characteristics as well as success of patient recruitment.

RESULTS

Studies that focused on prevalent cases were more successful than studies that required incident cases. Studies in which the general practitioner (GP) had to be alert during consultations were less successful. When the GP or practice assistant was the first to inform the patient about the study, patient recruitment was less successful than when the patient received a letter by mail. There was a strong association among these three factors.

CONCLUSION

Lasagna's Law also holds in Dutch primary care research: many studies face recruitment problems. Awareness of study characteristics affecting participation of GPs and patients may help investigators to improve their study design.

Research methods courses as a means of developing academic general practice. Fifteen years' experience from Sweden and Denmark

Since 1989, the authors have given courses in research methodology, and these courses are now given at six venues in southern Sweden, as well as in Denmark. The course corresponds to half a year's full-time study, with half the time devoted to lectures and studies of literature, while the rest is spent on an individual project under supervision. To enable part-time study, the course extends over 1(1/2) years. In 15 years roughly 1000 people, mainly physicians, have been given training in basic research methods. The course model has been appreciated by clinically active colleagues, who have been able to attend a course and simultaneously work with patients. Among the GPs in the region, one in five has taken this course, and one in five has then gone on to start formal PhD studies. The authors have thus succeeded in their goal of giving basic scientific schooling to many physicians and recruiting some for further research.
