Primary care indicators for disease burden, monitoring and surveillance of COVID-19 in 31 European countries: Eurodata Study.

BACKGROUND: During the COVID-19 pandemic, the majority of patients received ambulatory treatment, highlighting the importance of primary health care (PHC). However, there is limited knowledge regarding PHC workload in Europe during this period. The utilization of COVID-19 PHC indicators could facilitate the efficient monitoring and coordination of the pandemic response. The objective of this study is to describe PHC indicators for disease surveillance and monitoring of COVID-19's impact in Europe. METHODS: Descriptive, cross-sectional study employing data obtained through a semi-structured ad hoc questionnaire, which was collectively agreed upon by all participants. The study encompasses PHC settings in 31 European countries from March 2020 to August 2021. Key-informants from each country answered the questionnaire. Main outcome: the identification of any indicator used to describe PHC COVID-19 activity. RESULTS: Out of the 31 countries surveyed, data on PHC information were obtained from 14. The principal indicators were: total number of cases within PHC (Belarus, Cyprus, Italy, Romania and Spain), number of follow-up cases (Croatia, Cyprus, Finland, Spain and Turkey), GP's COVID-19 tests referrals (Poland), proportion of COVID-19 cases among respiratory illnesses consultations (Norway and France), sick leaves issued by GPs (Romania and Spain) and examination and complementary tests (Cyprus). All COVID-19 cases were attended in PHC in Belarus and Italy. CONCLUSIONS: The COVID-19 pandemic exposes a crucial deficiency in preparedness for infectious diseases in European health systems highlighting the inconsistent recording of indicators within PHC organizations. PHC standardized indicators and public data accessibility are urgently needed, conforming the foundation for an effective European-level health services response framework against future pandemics.

The role of primary health care in long-term care facilities during the COVID-19 pandemic in 30 European countries: a retrospective descriptive study (Eurodata study).

BACKGROUND AND AIM: Primary health care (PHC) supported long-term care facilities (LTCFs) in attending COVID-19 patients. The aim of this study is to describe the role of PHC in LTCFs in Europe during the early phase of the pandemic. METHODS: Retrospective descriptive study from 30 European countries using data from September 2020 collected with an ad hoc semi-structured questionnaire. Related variables are SARS-CoV-2 testing, contact tracing, follow-up, additional testing, and patient care. RESULTS: Twenty-six out of the 30 European countries had PHC involvement in LTCFs during the COVID-19 pandemic. PHC participated in initial medical care in 22 countries, while, in 15, PHC was responsible for SARS-CoV-2 test along with other institutions. Supervision of individuals in isolation was carried out mostly by LTCF staff, but physical examination or symptom's follow-up was performed mainly by PHC. CONCLUSION: PHC has participated in COVID-19 pandemic assistance in LTCFs in coordination with LTCF staff, public health officers, and hospitals.

Clinical pathway of COVID-19 patients in primary health care in 30 European countries: Eurodata study.

BACKGROUND: Most COVID-19 patients were treated in primary health care (PHC) in Europe. OBJECTIVES: To demonstrate the scope of PHC workflow during the COVID-19 pandemic emphasising similarities and differences of patient's clinical pathways in Europe. METHODS: Descriptive, cross-sectional study with data acquired through a semi-structured questionnaire in PHC in 30 European countries, created ad hoc and agreed upon among all researchers who participated in the study. GPs from each country answered the approved questionnaire. Main variable: PHC COVID-19 acute clinical pathway. All variables were collected from each country as of September 2020. RESULTS: COVID-19 clinics in PHC facilities were organised in 8/30. Case detection and testing were performed in PHC in 27/30 countries. RT-PCR and lateral flow tests were performed in PHC in 23/30, free of charge with a medical prescription. Contact tracing was performed mainly by public health authorities. Mandatory isolation ranged from 5 to 14 days. Sick leave certification was given exclusively by GPs in 21/30 countries. Patient hotels or other resources to isolate patients were available in 12/30. Follow-up to monitor the symptoms and/or new complementary tests was made mainly by phone call (27/30). Chest X-ray and phlebotomy were performed in PHC in 18/30 and 23/30 countries, respectively. Oxygen and low-molecular-weight heparin were available in PHC (21/30). CONCLUSION: In Europe PHC participated in many steps to diagnose, treat and monitor COVID-19 patients. Differences among countries might be addressed at European level for the management of future pandemics.

Understanding older patients' willingness to have medications deprescribed in primary care: a protocol for a cross-sectional survey study in nine European countries.

INTRODUCTION: To reduce inappropriate polypharmacy, deprescribing should be part of patients' regular care. Yet deprescribing is difficult to implement, as shown in several studies. Understanding patients' attitudes towards deprescribing at the individual and country level may reveal effective ways to involve older adults in decisions about medications and help to implement deprescribing in primary care settings. In this study we aim to investigate older adults' perceptions and views on deprescribing in different European countries. Specific objectives are to investigate the patients' willingness to have medications deprescribed by medication type and to have herbal or dietary supplements reduced or stopped, the role of the Patient Typology (on medication perspectives), and the impact of the patient-GP relationship in these decisions. METHODS AND ANALYSIS: This cross-sectional survey study has two parts: Part A and Part B. Data collection for Part A will take place in nine countries, in which per country 10 GPs will recruit 10 older patients (≥65 years old) each (n = 900). Part B will be conducted in Switzerland only, in which an additional 35 GPs will recruit five patients each and respond to a questionnaire themselves, with questions about the patients' medications, their willingness to deprescribe those, and their patient-provider relationship. For both Part A and part B, a questionnaire will be used to assess the willingness of older patients with polypharmacy to have medications deprescribed and other relevant information. For Part B, this same questionnaire will have additional questions on the use of herbal and dietary supplements. DISCUSSION: The international study design will allow comparisons of patient perspectives on deprescribing from different countries. We will collect information about willingness to have medications deprescribed by medication type and regarding herbal and dietary supplements, which adds important information to the literature on patients' preferences. In addition, GPs in Switzerland will also be surveyed, allowing us to compare GPs' and patients' views and preferences on stopping or reducing specific medications. Our findings will help to understand patients' attitudes towards deprescribing, contributing to improvements in the design and implementation of deprescribing interventions that are better tailored to patients' preferences.

Primary Care System Factors and Clinical Decision-making in Patients that Could Have Lung Cancer: a Vignette Study in Five Balkan Region Countries.

INTRODUCTION: Lung cancer is the leading cause of cancer death, with wide variations in national survival rates. This study compares primary care system factors and primary care practitioners' (PCPs') clinical decision-making for a vignette of a patient that could have lung cancer in five Balkan region countries (Slovenia, Croatia, Bulgaria, Greece, Romania). METHODS: PCPs participated in an online questionnaire that asked for demographic data, practice characteristics, and information on health system factors. Participants were also asked to make clinical decisions in a vignette of a patient with possible lung cancer. RESULTS: The survey was completed by 475 PCPs. There were significant national differences in PCPs' direct access to investigations, particularly to advanced imaging. PCPs from Bulgaria, Greece, and Romania were more likely to organise relevant investigations. The highest specialist referral rates were in Bulgaria and Romania. PCPs in Bulgaria were less likely to have access to clinical guidelines, and PCPs from Slovenia and Croatia were more likely to have access to a cancer fast-track specialist appointment system. The PCPs' country had a significant effect on their likelihood of investigating or referring the patient. CONCLUSIONS: There are large differences between Balkan region countries in PCPs' levels of direct access to investigations. When faced with a vignette of a patient with the possibility of having lung cancer, their investigation and referral rates vary considerably. To reduce diagnostic delay in lung cancer, direct PCP access to advanced imaging, availability of relevant clinical guidelines, and fast-track referral systems are needed.

Risk stratification in heart failure decompensation in the community: HEFESTOS score.

AIMS: Because evidence regarding risk stratification predicting prognosis of patients with heart failure (HF) decompensation attended in primary care is lacking, we developed and externally validated a model to forecast death/hospitalization during the first 30 days after an episode of decompensation. The predictive model is based on variables easily obtained in primary care settings. METHODS AND RESULTS: HEFESTOS is a multinational study consisting of a derivation cohort of HF patients recruited in 14 primary healthcare centres in Barcelona and a validation cohort from primary healthcare in 9 other European countries. The derivation and validation cohorts included 561 and 250 patients, respectively. Percentages of women in the derivation and validation cohorts were 56.3% and 47.6% (P = 0.026), respectively. Mean age was 82.2 years (SD 8.03) in the derivation cohort, and 79.3 years (SD 10.3) in the validation one (P = 0.001). HF with preserved ejection fraction represented 72.1% in the derivation cohort and 58.8% in the validation one (P = 0.004). Mortality/hospitalization during the first 30 days after a decompensation episode was 30.5% and 26% (P = 0.225) for the derivation and validation cohorts, respectively. Multivariable logistic regression models were performed to develop a score of risk. The identified predictors were worsening of dyspnoea [odds ratio (OR): 2.5; P = 0.001], orthopnoea (OR: 2.16; P = 0.01), paroxysmal nocturnal dyspnoea (OR: 2.25; P = 0.01), crackles (OR: 2.35; P = 0.01), New York Heart Association functional class III/IV (OR: 2.11; P = 0.001), oxygen saturation ≤ 90% (OR: 4.98; P < 0.001), heart rate > 100 b.p.m. (OR: 2.72; P = 0.002), and previous hospitalization due to HF (OR: 2.45; P < 0.001). The model showed an area under the curve (AUC) of 0.807, 95% confidence interval (CI): [0.770; 0.845] in the derivation cohort and AUC 0.73, 95% CI: [0.660; 0.808] in the validation one. No significant differences between both cohorts were observed (P = 0.08). Regarding probability of hospitalization/death, three risk groups were defined: low <5%, medium 5-20%, and high >20%. Outcome incidence was 2.7% for the low-risk group, 12.8% for medium risk, and 46.2% for high risk in the derivation cohort, and 9.1%, 12.9%, and 39.6% in the validation one. CONCLUSIONS: The HEFESTOS score, based on variables easily accessible in a community setting and validated in an external European cohort, properly predicted the risk of death/hospitalization during the first 30 days after an HF decompensation episode.

Nine Forward-Backward Translations of the Hopkins Symptom Checklist-25 With Cultural Checks.

Introduction: The Hopkins Symptom Checklist-25 (HSCL-25) is an effective, reliable, and ergonomic tool that can be used for depression diagnosis and monitoring in daily practice. To allow its broad use by family practice physicians (FPs), it was translated from English into nine European languages (Greek, Polish, Bulgarian, Croatian, Catalan, Galician, Spanish, Italian, and French) and the translation homogeneity was confirmed. This study describes this process. Methods: First, two translators (an academic translator and an FP researcher) were recruited for the forward translation (FT). A panel of English-speaking FPs that included at least 15 experts (researchers, teachers, and practitioners) was organized in each country to finalize the FT using a Delphi procedure. Results: One or two Delphi procedure rounds were sufficient for each translation. Then, a different translator, who did not know the original version of the HSCL-25, performed a backward translation in English. An expert panel of linguists compared the two English versions. Differences were listed and a multicultural consensus group determined whether they were due to linguistic problems or to cultural differences. All versions underwent cultural check. Conclusion: All nine translations were finalized without altering the original meaning.

General practitioners' deprescribing decisions in older adults with polypharmacy: a case vignette study in 31 countries.

BACKGROUND: General practitioners (GPs) should regularly review patients' medications and, if necessary, deprescribe, as inappropriate polypharmacy may harm patients' health. However, deprescribing can be challenging for physicians. This study investigates GPs' deprescribing decisions in 31 countries. METHODS: In this case vignette study, GPs were invited to participate in an online survey containing three clinical cases of oldest-old multimorbid patients with potentially inappropriate polypharmacy. Patients differed in terms of dependency in activities of daily living (ADL) and were presented with and without history of cardiovascular disease (CVD). For each case, we asked GPs if they would deprescribe in their usual practice. We calculated proportions of GPs who reported they would deprescribe and performed a multilevel logistic regression to examine the association between history of CVD and level of dependency on GPs' deprescribing decisions. RESULTS: Of 3,175 invited GPs, 54% responded (N = 1,706). The mean age was 50 years and 60% of respondents were female. Despite differences across GP characteristics, such as age (with older GPs being more likely to take deprescribing decisions), and across countries, overall more than 80% of GPs reported they would deprescribe the dosage of at least one medication in oldest-old patients (> 80 years) with polypharmacy irrespective of history of CVD. The odds of deprescribing was higher in patients with a higher level of dependency in ADL (OR =1.5, 95%CI 1.25 to 1.80) and absence of CVD (OR =3.04, 95%CI 2.58 to 3.57). INTERPRETATION: The majority of GPs in this study were willing to deprescribe one or more medications in oldest-old multimorbid patients with polypharmacy. Willingness was higher in patients with increased dependency in ADL and lower in patients with CVD.

Precipitating factors of heart failure decompensation, short-term morbidity and mortality in patients attended in primary care.

OBJECTIVE: To evaluate the precipitating factors for heart failure decompensation in primary care and associations with short-term prognosis. Design Prospective cohort study with a 30-d follow-up from an index consultation. Regression models to determine independent factors associated with hospitalisation or death. SETTING: Primary care in ten European countries. Patients Patients with diagnosis of heart failure attended in primary care for a heart failure decompensation (increase of dyspnoea, unexplained weight gain or peripheral oedema). MAIN OUTCOME MEASURES: Potential precipitating factors for decompensation of heart failure and their association with the event of hospitalisation or mortality 30 d after a decompensation. RESULTS: Of 692 patients 54% were women, mean age 81 (standard deviation [SD] 8.9) years; mean left ventricular ejection fraction (LVEF) 55% (SD 12%). Most frequently identified heart failure precipitation factors were respiratory infections in 194 patients (28%), non-compliance of dietary recommendations in 184 (27%) and non-compliance with pharmacological treatment in 157 (23%). The two strongest precipitating factors to predict 30 d hospitalisation or death were respiratory infections (odds ratio [OR] 2.8, 95% confidence interval [CI] (2.4-3.4)) and atrial fibrillation (AF) > 110 beats/min (OR 2.2, CI 1.5-3.2). Multivariate analysis confirmed the association between the following variables and hospitalisation/death: In relation to precipitating factors: respiratory infection (OR 1.19, 95% CI 1.14-1.25) and AF with heart rate > 110 beats/min (OR 1.22, 95% CI 1.10-1.35); and regarding patient characteristics: New York Heart Association (NYHA) III or IV (OR 1.22, 95% CI 1.15-1.29); previous hospitalisation (OR 1.15, 95% CI 1.11-1.19); and LVEF < 40% (OR 1.14, 95% CI 1.09-1.19). CONCLUSIONS: In primary care, respiratory infections and rapid AF are the most important precipitating factors for hospitalisation and death within 30 d following an episode of heart failure decompensation. Key points Hospitalisation due to heart failure decompensation represents the highest share of healthcare costs for this disease. So far, no primary care studies have analysed the relationship between precipitating factors and short term prognosis of heart failure decompensation episodes. We found that in 692 patients with heart failure decompensation in primary care, the respiratory infection and rapid atrial fibrillation (AF) increased the risk of short-term hospital admission or death. Patients with a hospital admission the previous year and a decompensation episode caused by respiratory infection were even more likely to be hospitalized or die within 30 d.

External validation of multidimensional prognostic indices (ADO, BODEx and DOSE) in a primary care international cohort (PROEPOC/COPD cohort).

BACKGROUND: Due to the heterogeneous and systemic nature of the chronic obstructive pulmonary disease (COPD), the new guidelines are oriented toward individualized attention. Multidimensional scales could facilitate its proper clinical and prognostic assessment, but not all of them were validated in an international primary care cohort, different from the original ones used for model development. Therefore, our main aim is to assess the prognostic capacity of the ADO, BODEx and DOSE indices in primary care for predicting mortality in COPD patients and to validate the models obtained in subgroups of patients, classified by revised Global Initiative for Chronic Obstructive Lung Disease (2011) and updated Spanish Guideline (2014). Besides, we want to confirm that the prognostic capacity of all indices increases if the number of exacerbations is substituted by the interval between them and to assess the impact on health of the patient's lifestyle, social network and adherence to treatment. METHODS: Design: External validation of scales, open and prospective cohort study in primary care. SETTING: 36 health centres in 6 European high, medium and low income countries. SUBJECTS: 477 patients diagnosed with COPD, captured in clinical visit by their General Practitioner/Nurse. PREDICTORS: Detailed patient history, exacerbations, lung function test and questionnaires at baseline. OUTCOMES: Exacerbations, all-cause mortality and specific mortality, within 5 years of recruitment. ANALYSIS: Multivariate logistic regression and Cox regression will be used. Possible non-linear effect of the indices will be studied by using Structured Additive Regression models with penalised splines. Subsequently, we will assess different aspects of the regression models: discrimination, calibration and diagnostic precision. Clinical variables modulated in primary care and the interval between exacerbations will be considered and incorporated into the analysis. DISCUSSION: The Research Agenda for General Practice/Family Medicine highlights that the evidence on predictive values of prognostic indices in primary care is scarce. A prospective cohort like that of PROEPOC/COPD provides good opportunities for research into COPD and make communication easier between family practitioners, nursing staff, pneumologists and other professionals, supporting a multi-disciplinary approach to the treatment of these patients.

How do general practitioners recognize the definition of multimorbidity? A European qualitative study.

BACKGROUND: Multimorbidity is a challenging concept for general practice. An EGPRN working group has published a comprehensive definition of the concept of multimorbidity. As multimorbidity could be a way to explore complexity in general practice, it was of importance to explore whether European general practitioners (GPs) recognize this concept and whether they would change it. OBJECTIVES: To investigate whether European GPs recognize the EGPRN concept of multimorbidity and whether they would change it. METHODS: Focus group meetings and semi-structured interviews as data collection techniques with a purposive sample of practicing GPs from every country. Data collection continued until saturation was reached in every country. The analysis was undertaken using a grounded theory based method. In each national team, four independent researchers, working blind and pooling data, carried out the analysis. To ensure the internationalization of the data, an international team of 10 researchers pooled the axial and selective coding of all national teams to check the concept and highlight emerging themes. RESULTS: The maximal variation and saturation of the sample were reached in all countries with 211 selected GPs. The EGPRN definition was recognized in all countries. Two additional ideas emerged, the use of Wonca's core competencies of general practice, and the dynamics of the doctor-patient relationship for detecting and managing multimorbidity and patient's complexity. CONCLUSION: European GPs recognized and enhanced the EGPRN concept of multimorbidity. These results open new perspectives regarding the management of complexity using the concept of multimorbidity in general practice. [Box: see text].

The European general practice research network presents the translations of its comprehensive definition of multimorbidity in family medicine in ten European languages.

BACKGROUND: Multimorbidity, according to the World Health Organization, exists when there are two or more chronic conditions in one patient. This definition seems inaccurate for the holistic approach to Family Medicine (FM) and long-term care. To avoid this pitfall the European General Practitioners Research Network (EGPRN) designed a comprehensive definition of multimorbidity using a systematic literature review. OBJECTIVE: To translate that English definition into European languages and to validate the semantic, conceptual and cultural homogeneity of the translations for further research. METHOD: Forward translation of the EGPRN's definition of multimorbidity followed by a Delphi consensus procedure assessment, a backward translation and a cultural check with all teams to ensure the homogeneity of the translations in their national context. Consensus was defined as 70% of the scores being higher than 6. Delphi rounds were repeated in each country until a consensus was reached. RESULTS: 229 European medical expert FPs participated in the study. Ten consensual translations of the EGPRN comprehensive definition of multimorbidity were achieved. CONCLUSION: A comprehensive definition of multimorbidity is now available in English and ten European languages for further collaborative research in FM and long-term care.

The Effect of Educational Intervention on the Patient's Willingness to Carry out the Immunochemical Faecal Occult Blood Test for Colorectal Cancer.

BACKGROUND: There is now compelling evidence that screening for colorectal cancer may result in significantly reduced mortality. Screening tests for colorectal cancer are not systematically performed in Bulgaria. AIM: This article explores the effect of an educational intervention on the willingness of patients to participate in the screening for colorectal cancer with the immunochemical faecal occult blood test in the home setting. MATERIALS AND METHODS: A before-after design study of the effects of educational intervention comprising distribution of a brochure and one-to-one discussion with a GP. A self-administered, original questionnaire was administered before and after the intervention to 600 randomly selected patients in 40 general practices (15 patients per practice) in Plovdiv district. RESULTS: The intervention led to an increase with >20% of the patient's knowledge of the importance of the test and on how to carry out the test. Statistical analysis indicated that there was an increase in knowledge after the educational intervention about the usefulness of the test (24.8% in males, 18.3% in females) and its performance (22.7% in males, 25.4% in females). CONCLUSION: The educational intervention has significantly influenced the patient's awareness about the test's usefulness and its self-administration. It improved the awareness by providing an easy access to information, thus fostering the active involvement of the patients. A strength of the intervention was the patient-centered approach in providing additional information through one-to-one discussions, and it ensured a higher quality of the preventive screening in the general practice.

Cross-Cultural Validation of the Definition of Multimorbidity in the Bulgarian Language.

INTRODUCTION: Multimorbidity is a health issue with growing importance. During the last few decades the populations of most countries in the world have been ageing rapidly. Bulgaria is affected by the issue because of the high prevalence of ageing population in the country with multiple chronic conditions. The AIM of the present study was to validate the translated definition of multimorbidity from English into the Bulgarian language. MATERIALS AND METHODS: The present study is part of an international project involving 8 national groups. We performed a forward and backward translation of the original English definition of multimorbidity using a Delphi consensus procedure. RESULTS: The physicians involved accepted the definition with a high percentage of agreement in the first round. The backward translation was accepted by the scientific committee using the Nominal group technique. DISCUSSION: Some of the GPs provided comments on the linguistic expressions which arose in order to improve understanding in Bulgarian. The remarks were not relevant to the content. The conclusion of the discussion, using a meta-ethnographic approach, was that the differences were acceptable and no further changes were required. CONCLUSIONS: A native version of the published English multimorbidity definition has been finalized. This definition is a prerequisite for better management of multimorbidity by clinicians, researchers and policy makers.

Say it in Croatian--Croatian translation of the EGPRN definition of multimorbidity using a Delphi consensus technique.

Patients coming to their family physician (FP) usually have more than one condition or problem. Multimorbidity as well as dealing with it, is challenging for FPs even as a mere concept. The World Health Organization (WHO) has simply defined multimorbidity as two or more chronic conditions existing in one patient. However, this definition seems inadequate for a holistic approach to patient care within Family Medicine. Using systematic literature review the European General Practitioners Research Network (EGPRN) developed a comprehensive definition of multimorbidity. For practical and wider use, this definition had to be translated into other languages, including Croatian. Here presented is the Croatian translation of this comprehensive definition using a Delphi consensus procedure for forward/backward translation. 23 expert FPs fluent in English were asked to rank the translation from 1 (absolutely disagreeable) to 9 (fully agreeable) and to explain each score under 7. It was previously defined that consensus would be reached when 70% of the scores are above 6. Finally, a backward translation from Croatian into English was undertaken and approved by the authors of the English definition. Consensus was reached after the first Delphi round with 100% of the scores above 6; therefore the Croatian translation was immediately accepted. The authors of the English definition accepted the backward translation. A comprehensive definition of multimorbidity is now available in English and Croatian, as well as other European languages which will surely make further implications for clinicians, researchers or policy makers.

Hidden patients: the relatives of patients in need of palliative care.

BACKGROUND: When identifying patients for palliative care, medical specialists find it necessary to disclose "hidden" patients: the patient's relatives. The issue has been discussed sporadically in Bulgaria; the present study was part of a larger investigation that examined the opinion of medical specialists, patients, and their relatives. METHOD: The study protocol was explained to participants who gave written informed consent. Patients (n=211) were followed up on by their general practitioners (GPs) (n=42) during one year. All relatives were invited, and 173 (82%) agreed and participated. A questionnaire created by the authors was used. The data were analyzed by frequency distribution (descriptive statistics) and nonparametric tests (Pearson's χ(2)) and statistically processed using SPSS 17.0 (SPSS Inc., Chicago, IL). RESULTS: Relatives providing care were predominantly women, two-thirds over 60 years of age. There was a one-to-one ratio between caregivers for oncological and nononcological patients. The duration of care was more than one year in 53% of cases. Most relatives reported their loved ones found physical suffering "very hard to bear" (53%), while approximately 17% could not assess the extent of psychological suffering. The vast majority stated that they had difficulties in providing care, and 68% had financial problems in that respect. CONCLUSION: Including relatives as users and part of the palliative care team has been discussed in the literature. In Bulgaria, participation is solely due to the lack of organized services for palliative care. Relatives participate in activities that are performed by trained staff in countries with developed palliative care; these activities, along with negative emotional experiences and economic difficulties, overburden these caregiving relatives significantly.
