Potential impact of a new sepsis prediction model for the primary care setting: early health economic evaluation using an observational cohort.

OBJECTIVES: To estimate the potential referral rate and cost impact at different cut-off points of a recently developed sepsis prediction model for general practitioners (GPs). DESIGN: Prospective observational study with decision tree modelling. SETTING: Four out-of-hours GP services in the Netherlands. PARTICIPANTS: 357 acutely ill adult patients assessed during home visits. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome is the cost per patient from a healthcare perspective in four scenarios based on different cut-off points for referral of the sepsis prediction model. Second, the number of hospital referrals for the different scenarios is estimated. The potential impact of referral of patients with sepsis on mortality and hospital admission was estimated by an expert panel. Using these study data, a decision tree with a time horizon of 1 month was built to estimate the referral rate and cost impact in case the model would be implemented. RESULTS: Referral rates at a low cut-off (score 2 or 3 on a scale from 0 to 6) of the prediction model were higher than observed for patients with sepsis (99% and 91%, respectively, compared with 88% observed). However, referral was also substantially higher for patients who did not need hospital assessment. As a consequence, cost-savings due to referral of patients with sepsis were offset by increased costs due to unnecessary referral for all cut-offs of the prediction model. CONCLUSIONS: Guidance for referral of adult patients with suspected sepsis in the primary care setting using any cut-off point of the sepsis prediction model is not likely to save costs. The model should only be incorporated in sepsis guidelines for GPs if improvement of care can be demonstrated in an implementation study. TRIAL REGISTRATION NUMBER: Dutch Trial Register (NTR 7026).

Predicting sepsis-related mortality and ICU admissions from telephone triage information of patients presenting to out-of-hours GP cooperatives with acute infections: A cohort study of linked routine care databases.

BACKGROUND: General practitioners (GPs) often assess patients with acute infections. It is challenging for GPs to recognize patients needing immediate hospital referral for sepsis while avoiding unnecessary referrals. This study aimed to predict adverse sepsis-related outcomes from telephone triage information of patients presenting to out-of-hours GP cooperatives. METHODS: A retrospective cohort study using linked routine care databases from out-of-hours GP cooperatives, general practices, hospitals and mortality registration. We included adult patients with complaints possibly related to an acute infection, who were assessed (clinic consultation or home visit) by a GP from a GP cooperative between 2017-2019. We used telephone triage information to derive a risk prediction model for sepsis-related adverse outcome (infection-related ICU admission within seven days or infection-related death within 30 days) using logistic regression, random forest, and neural network machine learning techniques. Data from 2017 and 2018 were used for derivation and from 2019 for validation. RESULTS: We included 155,486 patients (median age of 51 years; 59% females) in the analyses. The strongest predictors for sepsis-related adverse outcome were age, type of contact (home visit or clinic consultation), patients considered ABCD unstable during triage, and the entry complaints"general malaise", "shortness of breath" and "fever". The multivariable logistic regression model resulted in a C-statistic of 0.89 (95% CI 0.88-0.90) with good calibration. Machine learning models performed similarly to the logistic regression model. A "sepsis alert" based on a predicted probability >1% resulted in a sensitivity of 82% and a positive predictive value of 4.5%. However, most events occurred in patients receiving home visits, and model performance was substantially worse in this subgroup (C-statistic 0.70). CONCLUSION: Several patient characteristics identified during telephone triage of patients presenting to out-of-hours GP cooperatives were associated with sepsis-related adverse outcomes. Still, on a patient level, predictions were not sufficiently accurate for clinical purposes.

Pandemic preparedness and management in European out-of-hours primary care services - a descriptive study.

BACKGROUND: Primary care is the first point of contact for all acute health problems. As such, primary care was at the frontline in the COVID-19 pandemic, playing a significant role in clinical responses and information to the public. This study aimed to describe the variations in patient management strategies used in the out-of-hours services in different European countries during the first phase of the pandemic. METHOD: We conducted a cross-sectional web-based survey in August 2020, selecting key informants from European countries using European networks. The questionnaire was developed in collaboration with researchers in the field of out-of-hours primary care. We performed descriptive analyses per region, structuring results into themes. RESULTS: Key informants from 38 regions in 20 European countries responded. Seven regions reported that their out-of-hours services had a pandemic preparedness plan, three had trained on the plan, and two had stockpiles of personal protection equipment before the outbreak. Extension of telephone triage lines and establishment of local infection-control teams and clinics were the main patient management strategies. Other strategies for patient contacts were also used in the regions, such as video-consultations (13 regions), electronic consultations (21 regions), patient's car as alternative waiting room (19 regions), outside tents for testing (24 regions), "drive-through" testing (26 regions), and separate departments for infected patients (14 regions). CONCLUSION: Few out-of-hours services were well prepared for a pandemic, but all expanded and reorganized rapidly, adopting new strategies for patient management and treatment. The results could be useful for planning of organization preparedness of out-of-hours primary care service for future pandemics.

The accuracy and feasibility of respiratory rate measurements in acutely ill adult patients by GPs: a mixed-methods study.

BACKGROUND: Tachypnoea in acutely ill patients can be an early sign of a life-threatening condition such as sepsis. Routine measurement of the respiratory rate by GPs might improve the recognition of sepsis. AIM: To assess the accuracy and feasibility of respiratory rate measurements by GPs. DESIGN & SETTING: Observational cross-sectional mixed-methods study in the setting of out-of-hours (OOH) home visits at three GP cooperatives in The Netherlands. METHOD: GPs were observed during the assessment of acutely ill patients, and semi-structured interviews were performed. The GP-assessed respiratory rate was compared with a reference measurement. In the event that the respiratory rate was not counted, GPs were asked to estimate the rate (dichotomised as ≥22 breaths per minute or <22 breaths per minute). RESULTS: Observations of 130 acutely ill patients were included, and 14 GPs were interviewed. In 33 patients (25%), the GP counted the respiratory rate. A mean difference of 0.27 breaths per minute (95% confidence interval [CI] = -5.7 to 6.3) with the reference measurement was found. At a cut-off point of ≥22 breaths per minute, a sensitivity of 86% (95% CI = 57% to 98%) was found when the GP counted the rate, and a sensitivity of 43% (95% CI = 22% to 66%) when GPs estimated respiratory rates. GPs reported both medical and practical reasons for not routinely measuring the respiratory rate. CONCLUSION: GPs are aware of the importance of assessing the respiratory rate of acutely ill adult patients, and counted measurements are accurate. However, in most patients the respiratory rate was not counted, and the rate was often underestimated when estimated.

Early experiences with quality-assured HbA1c and professional glucose point-of-care testing in general practice: a cross-sectional observational study among patients, nurses and doctors.

BACKGROUND: Point-of-care testing (POCT) is increasingly used in primary care. The rapid availability of the test result during the patient encounter increases the potential for patients and care providers to make a direct and joint decision on disease management. Our aim was to get insight into the first experiences of patients and healthcare professionals after introducing quality-controlled HbA1c and professional glucose POCT in diabetes care in their own general practices. METHODS: A cross-sectional observational study using paper questionnaires for patients, nurses and general practitioners (GPs) in 13 general practices in the Netherlands. HbA1c and professional glucose POCT was introduced after training and under day-to-day quality control. Patients filled in the questionnaire immediately after the test; nurses and GPs after a minimum period of three months from the starting date. Descriptive data analyses were performed. RESULTS: A total of 1551 fingerstick blood POC tests were performed (1126 HbA1c; 425 Glucose). For HbA1c POCT, 84 patients, 29 nurses and 11 GPs filled in the questionnaires. For professional glucose POCT, 30 patients, 17 nurses and 8 GPs responded. Response rates varied between 24 and 56%. Patients, nurses and GPs were generally (very) satisfied with the novel POC tests. Patients were most positive about the location (in the GPs' office) and execution of the POC test (by their own nurse), and the speed of the test result. Almost all nurses indicated to have sufficient knowledge and skills to perform the test. Both nurses and GPs had confidence in the test results and indicated they experienced a higher patient satisfaction than with regular blood tests. Perceived disadvantages were the time required to regularly calibrate the devices and the extension of the consultation time because of the test. Patients, nurses and GPs generally expressed they wanted to continue performing these POC tests in routine diabetes care. CONCLUSIONS: Patients, nurses and GPs expressed (very) positive first experiences after introducing HbA1c and professional glucose testing on two high-quality POCT devices in their own general practices. Further research, with a random selection procedure of practices and patients and in other regions and countries, is recommended to confirm these findings.

Added Diagnostic Value of Biomarkers in Patients with Suspected Sepsis: A Prospective Cohort Study in Out-Of-Hours Primary Care.

BACKGROUND: Point-of-care testing (POCT) has shown promising results in the primary care setting to improve antibiotic therapy in respiratory tract infections and it might also aid general practitioners (GPs) to decide if patients should be referred to a hospital in cases of suspected sepsis. We aimed to assess whether biomarkers with possible POCT use can improve the recognition of sepsis in adults in the primary care setting. METHODS: We prospectively included adult patients with suspected severe infections during out-of-hours home visits. Relevant clinical signs and symptoms were recorded, as well as the biomarkers C-reactive protein, lactate, procalcitonin, high-sensitive troponin I, N-terminal pro b-type natriuretic peptide, creatinine, urea, and pancreatic stone protein. We used a POCT device for lactate only, and the remaining biomarkers were measured in a laboratory from stored blood samples. The primary outcome was sepsis within 72 h of inclusion. The potential of biomarkers to either rule in or rule out sepsis was tested for individual biomarkers combined with a model consisting of signs and symptoms. Net reclassification indices were also calculated. RESULTS: In total, 336 patients, with a median age of 80 years, were included. One hundred forty-one patients (42%) were diagnosed with sepsis. The C statistic for the model with clinical symptoms and signs was 0.84 (95% CI 0.79-0.88). Both lactate and procalcitonin increased the C statistic to 0.85, but none of the biomarkers significantly changed the net reclassification index. CONCLUSIONS: We do not advocate the routine use of POCT in general practice for any of the tested biomarkers of suspected sepsis.

New clinical prediction model for early recognition of sepsis in adult primary care patients: a prospective diagnostic cohort study of development and external validation.

BACKGROUND: Recognising patients who need immediate hospital treatment for sepsis while simultaneously limiting unnecessary referrals is challenging for GPs. AIM: To develop and validate a sepsis prediction model for adult patients in primary care. DESIGN AND SETTING: This was a prospective cohort study in four out-of-hours primary care services in the Netherlands, conducted between June 2018 and March 2020. METHOD: Adult patients who were acutely ill and received home visits were included. A total of nine clinical variables were selected as candidate predictors, next to the biomarkers C-reactive protein, procalcitonin, and lactate. The primary endpoint was sepsis within 72 hours of inclusion, as established by an expert panel. Multivariable logistic regression with backwards selection was used to design an optimal model with continuous clinical variables. The added value of the biomarkers was evaluated. Subsequently, a simple model using single cut-off points of continuous variables was developed and externally validated in two emergency department populations. RESULTS: A total of 357 patients were included with a median age of 80 years (interquartile range 71-86), of which 151 (42%) were diagnosed with sepsis. A model based on a simple count of one point for each of six variables (aged >65 years; temperature >38°C; systolic blood pressure ≤110 mmHg; heart rate >110/min; saturation ≤95%; and altered mental status) had good discrimination and calibration (C-statistic of 0.80 [95% confidence interval = 0.75 to 0.84]; Brier score 0.175). Biomarkers did not improve the performance of the model and were therefore not included. The model was robust during external validation. CONCLUSION: Based on this study's GP out-of-hours population, a simple model can accurately predict sepsis in acutely ill adult patients using readily available clinical parameters.

Reliability and validity of the Netherlands Triage Standard in emergency care settings: a case scenario study.

BACKGROUND: The Netherlands Triage Standard (NTS) is a triage system that can be used by different types of emergency care organisations. Our objective was to determine the interrater reliability and construct validity of the NTS when applied to self-presenting patients. METHODS: We performed a cross-sectional case scenario study consisting of two parts: (1) paediatric triage in January-February 2019 and (2) adult triage in October-November 2020. In each part, we invited nurse triagists from three general practitioner cooperatives, three ambulance dispatching centres and three hospital emergency departments in the Netherlands to participate. We used 40 case scenarios involving paediatric patients and 41 involving adult patients who could self-present to any emergency care organisation. In advance, an expert panel determined the urgency (six levels) of the case scenarios (reference standard). The main outcome for reliability was the intraclass correlation coefficient (ICC) for urgency level. The main outcomes for validity were degree of agreement with the reference standard, for urgency level, and sensitivity and specificity for high versus low urgency. We used descriptive statistics and logistic multilevel modelling with both case and triagist as random effects. RESULTS: 218 out of 240 invited triagists participated. The ICC among all triagists was 0.73 for paediatric cases and 0.88 for adult cases and was highest in general practitioner cooperatives. For paediatric cases, there was 62.3% agreement with the reference standard about urgency, 17.4% underestimation and 20.2% overestimation. The sensitivity of the NTS for identifying highly urgent paediatric cases was 85.2%; the specificity was 89.7%. For adult cases, there was 68.3% agreement, 13.7% underestimation and 18.0% overestimation. The sensitivity of triage for high urgency in adults was 94.5% and the specificity 83.3%. CONCLUSION: NTS appears to have good reliability and construct validity for estimating the urgency of health complaints of non-referred patients presenting themselves in emergency care.

Developing an Evidence-Based Nursing Culture in Nursing Homes: An Action Research Study.

Background: Nursing homes face challenges caused by increasing numbers of older adults with multimorbidity and the demand for quality of care. Developing an evidence-based nursing (EBN) culture is a promising strategy to face these challenges. Therefore, the aim of this study was to develop an EBN culture in nursing homes and gain insight into the influencing factors. Methods: An action research study was conducted with 12 nursing teams in 4 Dutch nursing homes, using the Practice Development approach to develop an EBN culture. The teams (mostly certified nurse assistants) were coached by internal facilitators (bachelor's or master's degree nurses) and external facilitators (nursing teachers). Data were gathered at baseline and after 15 months using questionnaires and individual and focus group interviews. Results: With varying degrees, most nursing teams implemented elements (related to values, attitudes, and behaviors) of an EBN culture with appropriate leadership, advocacy, and training. The team members became open to new insights and asked critical questions. During the project, participants learned how EBN could be incorporated into daily practice, for example, by keeping it small, discussing information from professional journals, and using creative methods such as quizzes. Influencing factors of an EBN culture were: (a) support of managers, (b) inspiring facilitators close to the team, and (c) stable teams with driving forces and student nurses. Conclusions: Integrating EBN into daily practice in creative and motivating ways contributes to the development of an EBN culture in nursing homes. To facilitate this, managers should support teams in the process and content of EBN, and internal facilitators should collaborate with driving forces on the teams.

Effects of access to radiology in out-of-hours primary care on patient satisfaction and length of stay.

BACKGROUND: Direct access to hospital radiology facilities by general practitioner (GP) cooperatives is known to decrease the number of emergency department referrals, but the effects on length of stay (LOS; time from patient arrival at GP cooperative till departure to home) and patient experiences are unclear. OBJECTIVES: To provide insight into the LOS and experiences of trauma patients with an indication for radiology at GP cooperatives with and without access to radiology. METHODS: A multi-methods observational study in April 2014-October 2015 at six GP cooperatives in The Netherlands, covering three organisational models for access to radiology: no direct access, limited access and unlimited access. Patient experiences were measured with a questionnaire. Patient records were analysed for background characteristics, radiology outcomes, referral and LOS. RESULTS: In total 657 patients were included, 232 no direct access model, 307 limited access model and 118 unlimited access model. The mean LOS was 99 minutes, with a significant difference between GP cooperatives without access to radiology (121 minutes), with limited access (86 minutes), and with unlimited access (90 minutes). The differences were larger for patients without radiological abnormalities. On a ten-point scale, patients rated GP cooperatives with unlimited access to radiology higher (8.62) than those without access (8.36) or with limited access (8.39). CONCLUSION: Access to radiology by GP cooperatives seems to reduce the length of stay and is slightly more appreciated by patients. GP cooperatives with unlimited access seem to provide the most efficient and best-valued care, contributing to more patient-centred care.

Vital signs of the systemic inflammatory response syndrome in adult patients with acute infections presenting in out-of-hours primary care: A cross-sectional study.

BACKGROUND: Signs of the systemic inflammatory response syndrome (SIRS) - fever (or hypothermia), tachycardia and tachypnoea - are used in the hospital setting to identify patients with possible sepsis. OBJECTIVES: To determine how frequently abnormalities in the vital signs of SIRS are present in adult out-of-hours (OOH) primary care patients with suspected infections and assess the association with acute hospital referral. METHODS: We conducted a cross-sectional study at the OOH GP cooperative in Nijmegen, the Netherlands, between August and October 2015. GPs were instructed to record the body temperature, heart rate and respiratory rate of all patients with suspected acute infections. Vital signs of SIRS, other relevant signs and symptoms, and referral state were extracted from the electronic registration system of the OOH GP cooperative retrospectively. Logistic regression analysis was used to evaluate the association between clinical signs and hospital referral. RESULTS: A total of 558 patients with suspected infections were included. At least two SIRS vital signs were abnormal in 35/409 (8.6%) of the clinic consultations and 60/149 (40.3%) of the home visits. Referral rate increased from 13% when no SIRS vital sign was abnormal to 68% when all three SIRS vital signs were abnormal. Independent associations for referral were found for decreased oxygen saturation, hypotension and rapid illness progression, but not for individual SIRS vital signs. CONCLUSION: Although patients with abnormal vital signs of SIRS were referred more often, decreased oxygen saturation, hypotension and rapid illness progression seem to be most important for GPs to guide further management.

Examining Causes and Prevention Strategies of Adverse Events in Deceased Hospital Patients: A Retrospective Patient Record Review Study in the Netherlands.

OBJECTIVE: To improve patient safety and possibly prevent mortality from adverse events (AEs) in hospitals, it is important to gain insight in their underlying causes. We aimed to examine root causes and potential prevention strategies of AEs in deceased hospital patients. METHODS: Data on 571 AEs were used from two retrospective patient record review studies of patients who died during hospitalization in the Netherlands. Trained reviewers assessed contributing factors and potential prevention strategies. The results were analyzed together with data on preventability of the AE and the relationship of the AE with the death of the patient. RESULTS: In 47% of the AEs, patient-related causes were identified, in 35% human causes, in 9% organizational causes, and in 3% technical causes. Preventable AEs were caused by technical, organizational, and human causes (78%, 74%, and 74%, respectively) more often than by patient-related causes (33%). In addition, technical factors caused AEs leading to preventable death (78%) relatively often. Recommended strategies to prevent AEs were quality assurance/peer review, evaluation of safety behavior, improving procedures, and improving information and communication structures. CONCLUSIONS: Human failures played an important role in the causation of AEs in Dutch hospitals, because they occurred frequently and they were frequently the cause of preventable AEs. To a lesser extent, latent organizational and technical factors were identified. Patient-related factors were often identified, but the preventability of the AEs with these causes was low. For future research into causes of AEs, we recommend combining record review with interviewing.

The Incidence and Nature of Adverse Medical Device Events in Dutch Hospitals: A Retrospective Patient Record Review Study.

OBJECTIVES: Despite widespread use of medical devices and their increasing complexity, their contribution to unintended injury caused by healthcare (adverse events, AEs) remains relatively understudied. The aim of this study was to gain insight in the incidence and types of AEs involving medical devices (AMDEs). METHODS: Data from two patient record studies for the identification of AEs were used. Identification of AMDEs was part of these studies. Patient records of 6894 admissions of a random sample of 20 hospitals in 2011/2012 and 19 hospitals in 2015/2016 were reviewed for AMDEs by trained nurses and physicians. RESULTS: In 98.7% of the admissions, a medical device was used. Adverse events involving medical devices were present in 2.8% of the admissions, with 24% of the AMDEs being potentially preventable. Of all AEs, in 40%, medical devices were involved. Of all potentially preventable AEs, in 44%, medical devices were involved. Implants were most often involved in potentially preventable AMDEs. CONCLUSIONS: Medical devices are substantially involved in potentially preventable AEs in hospitals. Research into AMDEs is of great importance because of the increasing use and complexity of medical devices. Based on patient records, most improvements could be made for placement of implants and prevention of infections related to medical devices. Safety and safe use of medical devices should be a subject of attention and further research.

[The Netherlands Triage Standard applied to paediatric patients in emergency medicine: is it reliable and valid?] / Toepassing van de Nederlandse Triage Standaard bij kinderen in de spoedzorg.

OBJECTIVE: To determine the inter-rater reliability and validity of the Netherlands Triage Standard (NTS) for paediatric triage. DESIGN: A cross-sectional study using fictional cases for telephone and physical triage. METHOD: An expert panel established in advance the urgency of 40 cases concerning emergency help requests from non-referred children (the reference standard). These requests were presented in an online survey to triagists from three general practitioner (GP) out-of-hours practices, three ambulance dispatching centres and three hospital emergency departments. Triagists assessed all cases, using the NTS. We determined the agreement on degrees of urgency between different triagists and compared them with the reference standard. The outcome measure for inter-rater reliability was the intraclass correlation coefficient (ICC). The outcome measures for validity were the degree of agreement with the reference standard, under-triage and over-triage, and sensitivity and specificity in identifying high-urgency (U0-U2) versus low-urgency cases (U30U5). RESULTS: In total, 116 triagists participated in the study (response: 86%). The ICC was 0.73 among all triagists, and was highest in the out-of-hours GP cooperatives. There was 62.3% agreement with the reference standard, 17.4% under-triage and 20.2% over-triage. Of the divergent urgencies, 77% differed by only one urgency category. The sensitivity was 85.2% and the specificity 89.7%. The sensitivity and specificity of triage by the GP out-of-hours practices (82.7% and 92.7%, respectively) were almost the same as that by the hospital emergency departments (79.6% and 92.5%, respectively). Triage by the ambulance dispatching centres had relatively high sensitivity (93%), but relatively low specificity (82.4%). CONCLUSION: The results of the study contribute to the evidence that the NTS is a reliable and valid triage standard for paediatric patients. The urgency assessments by triagists in the GP out-of-hours practices, ambulance dispatching centres and hospital emergency departments were broadly in agreement. Results were limited by cases being on paper and triage only on anamnestic characteristics.

Development of a clinical prediction rule for sepsis in primary care: protocol for the TeSD-IT study.

BACKGROUND: Early recognition and treatment of sepsis is crucial to prevent detrimental outcomes. General practitioners (GPs) are often the first healthcare providers to encounter seriously ill patients. The aim of this study is to assess the value of clinical information and additional tests to develop a clinical prediction rule to support early diagnosis and management of sepsis by GPs. METHODS: We will perform a diagnostic study in the setting of out-of-hours home visits in four GP cooperatives in the Netherlands. Acutely ill adult patients suspected of a serious infection will be screened for eligibility by the GP. The following candidate predictors will be prospectively recorded: (1) age, (2) body temperature, (3) systolic blood pressure, (4) heart rate, (5) respiratory rate, (6) peripheral oxygen saturation, (7) mental status, (8) history of rigors, and (9) rate of progression. After clinical assessment by the GP, blood samples will be collected in all patients to measure C-reactive protein, lactate, and procalcitonin. All patients will receive care as usual. The primary outcome is the presence or absence of sepsis within 72 h after inclusion, according to an expert panel. The need for hospital treatment for any indication will be assessed by the expert panel as a secondary outcome. Multivariable logistic regression will be used to design an optimal prediction model first and subsequently derive a simplified clinical prediction rule that enhances feasibility of using the model in daily clinical practice. Bootstrapping will be performed for internal validation of both the optimal model and simplified prediction rule. Performance of both models will be compared to existing clinical prediction rules for sepsis. DISCUSSION: This study will enable us to develop a clinical prediction rule for the recognition of sepsis in a high-risk primary care setting to aid in the decision which patients have to be immediately referred to a hospital and who can be safely treated at home. As clinical signs and blood samples will be obtained prospectively, near-complete data will be available for analyses. External validation will be needed before implementation in routine care and to determine in which pre-hospital settings care can be improved using the prediction rule. TRIAL REGISTRATION: The study is registered in the Netherlands Trial Registry (registration number NTR7026).

Out-of-hours primary care in 26 European countries: an overview of organizational models.

BACKGROUND: Various models exist to organize out-of-hours primary care (OOH-PC). We aimed to provide an up-to-date overview of prevailing organizational models in the European Union (EU), implemented changes over the last decade and future plans. This baseline overview may provide information for countries considering remodelling their OOH-PC system. METHODS: A cross-sectional web-based questionnaire among 93 key informants from EU countries, Norway and Switzerland. Key informants with expertise in the field of primary health care were invited to participate. Themes in the questionnaire were the existing organizational models for OOH-PC, model characteristics, major organizational changes implemented in the past decade and future plans. RESULTS: All 26 included countries had different coexisting OOH-PC models, varying from 3 to 10 models per country. 'GP cooperative was the dominant model in most countries followed by primary care centre and rota group'. There was a large variation in characteristics between the models, but also within the models, caused by differences between countries and regions. Almost all countries had implemented changes over the past 10 years, mostly concerning the implementation of telephone triage and a change of organizational model by means of upscaling and centralization of OOH-PC. Planned changes varied from fine-tuning the prevailing OOH-PC system to radical nationwide organizational transitions in OOH-PC. CONCLUSIONS: Different organizational models for OOH-PC exist on international and national level. Compared with a decade ago, more primary care-oriented organizational models are now dominant. There is a trend towards upscaling and centralization; it should be evaluated whether this improves the quality of health care.

Substitution of general practitioners by nurse practitioners in out-of-hours primary care home visits: A quasi-experimental study.

BACKGROUND: General practitioners experience a high workload during out-of-hours care. A possible solution is the shifting of care to nurse practitioners. OBJECTIVES: To provide insight into patient- and care characteristics, safety, efficiency, and patient satisfaction of substituting general practitioners with nurse practitioners for home visits by out-of-hours primary care services. DESIGN: Quasi-experimental non-randomised study comparing home visits by nurse practitioners (intervention group; one out-of-hours care service) with home visits by general practitioners (control group; two out-of-hours care services) for 24 protocolised health problems. SETTING: Three out-of-hours primary care services in the East of the Netherlands. PARTICIPANTS: 1601 patients who received a home visit by a nurse practitioner (N = 386) or a general practitioner (N = 1215). Of these patients, 639 gave informed consent to be included in the protocol adherence assessment and follow-up record review (nurse practitioner: N = 358; general practitioner: N = 281). METHODS: Five nurse practitioners with experience in ambulance care were recruited and trained. From September 2016 to March 2017 the nurse practitioners took over home visits under supervision of a general practitioners. This was evaluated using: (1) data-extraction from the patient registration system, (2) follow-up record review in the patients' general practices, and (3) patient satisfaction survey. Two general practitioners independently assessed protocol adherence based on the extracted registration data. RESULTS: Nurse practitioners prescribed medication significantly less often than general practitioners (19.9% versus 30.6%), and referred patients significantly more often to the hospital (24.1% versus 15.9%). The mean length of the home visit was significantly longer for nurse practitioners (34.1 versus 21.1 min). Nurse practitioners adhered to the protocol significantly more often than general practitioners (84.9% versus 76.2%) and their medication prescribing was significantly more often appropriate (93.7% versus 79.5%). There were no differences in the number of missed diagnoses and complications. The number of follow-up contacts was also similar in both groups. Patient satisfaction was generally high and significantly higher for nurse practitioners on several items. CONCLUSIONS: Nurse practitioners with experience in ambulance care can safely, efficiently, and satisfactorily perform low complex out-of-hours primary care home visits. It is recommended to study the safety and efficiency of nurse practitioners' home visits in other regions and with nurse practitioners with different educational levels and different specialisations. In addition, we recommend to evaluate the cost-effectiveness and if it leads increased quality of care.

Examining differences in out-of-hours primary care use in Belgium and the Netherlands: a cross-sectional study.

BACKGROUND: The organizational model of out-of-hours primary care is likely to affect healthcare use. We aimed to examine differences in the use of general practitioner cooperatives for out-of-hours care in the Netherlands and Belgium (Flanders) and explore if these are related to organizational differences. METHODS: A cross-sectional observational study using routine electronic health record data of the year 2016 from 77 general practitioner cooperatives in the Netherlands and 5 general practitioner cooperatives in Belgium (Flanders). Patient age, gender and health problem were analyzed using descriptive statistics. RESULTS: The number of consultations per 1000 residents was 2.3 times higher in the Netherlands than in Belgium. Excluding telephone consultations, which are not possible in Belgium, the number of consultations was 1.4 times higher. In Belgium, the top 10 of health problems was mainly related to infections, while in the Netherlands there were a larger variety of health problems. In addition, the health problem codes in the Dutch top 10 were more often symptoms, while the codes in the Belgian top 10 were more often diagnoses. In both countries, a relatively large percentage of GPC patients were young children and female patients. CONCLUSION: Differences in the use of general practitioner cooperatives seem to be related to the gatekeeping role of general practitioners in the Netherlands and to organizational differences such as telephone triage, medical advice by telephone, financial thresholds and number of years of experience with the system. The information can benefit policy decisions about the organization of out-of-hours primary care.

Factors related to out-of-hours help-seeking for acute health problems: a survey study using case scenarios.

BACKGROUND: The acute out-of-hours healthcare services are challenged by increasing demand in many countries. We aimed to examine factors influencing the intended help-seeking in out-of-hours care for acute health problems during evenings, nights, and weekends. METHODS: We conducted a survey study based on data from parents of children (aged 0-4 years) and adults (aged 30-39 and 50-59 years) in Denmark, the Netherlands and Switzerland. Intended help-seeking behaviour was measured by six hypothetical case scenarios. We used Andersen's Behavioural Model to categorise potentially influential factors and applied multiple binomial regression to assess the influence of selected factors. RESULTS: A total of 1015 parents and 2942 adults participated. We identified several significant influential factors. Parents holding a low education (OR 1.56), having migrant background (western: OR 1.23; non-western: OR 1.93), having one child (OR 1.24), perceiving few barriers to using out-of-hours primary care (OR 1.59), perceiving difficulties with organising childcare (OR 1.13), and having a history of frequent contacts with out-of-hours care (OR 1.55) were more inclined to contact out-of-hours care, whereas female (OR 0.85) and non-anxious parents (OR 0.77) were less inclined. Adults who were older (OR 1.01), holding a medical education (OR 1.13), having non-western background (OR 1.28), being unemployed (OR 1.17), perceiving few barriers to using out-of-hours primary care (OR 1.37), and having a history of frequent contacts with a GP (few: OR 1.15; more: OR 1.22) and/or with out-of-hours care (one: OR 1.20; more: OR 1.49) were more inclined to contact out-of-hours care, whereas adults with no or little social support (OR 0.84) and adults with high health literacy level on health information (OR 0.91) were less inclined. Dutch parents were less inclined than Danish parents to contact out-of-hours care (OR 0.62), whereas Swiss adults were more inclined than Danish adults to contact out-of-hours care (OR 1.16). CONCLUSION: We identified several factors related to intended help-seeking in out-of-hours care. These results could be used to develop targeted interventions, but more research is needed to examine the underlying explanations for the identified differences.
