Key Takeaways
- About 1.4 million adults in the Netherlands are estimated to have prediabetes (insulin resistance common) and ~400,000 have undiagnosed type 2 diabetes — early GP detection matters. ([diabetesfonds.nl](https://www.diabetesfonds.nl/over-diabetes/wat-is-diabetes/diabetes-in-cijfers?utm_source=openai))
- GPs (huisartsen) can screen opportunistically (risk-based) with fasting plasma glucose, HbA1c or OGTT; use mmol/L units (fasting glucose: normal <5.6 mmol/L; cut-offs differ by guideline). ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/landelijke-eerstelijns-samenwerkingsafspraken/laboratoriumdiagnostiek?utm_source=openai))
- HOMA-IR (fasting insulin × fasting glucose / 22.5) is a research proxy for insulin resistance; thresholds vary so interpret together with clinical risk and other labs. ([academic.oup.com](https://academic.oup.com/ejendo/article/182/3/343/6653947?utm_source=openai))
- Lifestyle approaches (diet, physical activity, structured programmes) reduce progression from prediabetes to type 2 diabetes — primary care referral to proven programs is effective. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC11822313/?utm_source=openai))
- Frame recommendations for Dutch patients around the Schijf van Vijf, active (cycling) lifestyle and care pathways via huisarts and zorgverzekering — many GP services are covered and GP contacts do not count toward the eigen risico. ([voedingscentrum.nl](https://www.voedingscentrum.nl/nl/gezond-eten-met-de-schijf-van-vijf.aspx?utm_source=openai))
TL;DR
Huisartsen should use opportunistic, risk-based screening for insulin resistance / prediabetes using fasting glucose (mmol/L), HbA1c and clinical risk scores; when findings are borderline, combine lifestyle referral (Schijf van Vijf-based advice, structured DPP-style programmes) and repeat testing. National Dutch data show many people are undiagnosed — early detection in primary care can reduce later cardiovascular harm.

Introduction — a shocking Netherlands statistic
Recent Dutch estimates put at least 1.4 million people in a prediabetic state (a clinical picture closely tied to insulin resistance), while roughly 400,000 people may have diabetes type 2 without knowing it. That means many Dutch patients visiting the huisarts carry undetected metabolic risk that benefits from early assessment. ([diabetesfonds.nl](https://www.diabetesfonds.nl/over-diabetes/wat-is-diabetes/diabetes-in-cijfers?utm_source=openai))
Why the huisarts is central
In the Netherlands the huisarts is the first contact and gatekeeper for chronic disease prevention and early detection. Regular contacts, routine blood tests, and access via the basic zorgverzekering make primary care the ideal setting to spot insulin resistance early — and GP visits themselves do not reduce a patient’s eigen risico. ([rijksoverheid.nl](https://www.rijksoverheid.nl/vraag-en-antwoord/zorgverzekering/eigen-risico-zorgverzekering?utm_source=openai))
What is insulin resistance — quick primer for busy GPs
Insulin resistance (IR) means tissues need higher insulin levels to achieve normal glucose uptake. Clinically it often precedes prediabetes and type 2 diabetes and links tightly to abdominal obesity, dyslipidaemia, hypertension and fatty liver — the classic cardiometabolic cluster. Measures used in practice include fasting plasma glucose, HbA1c, oral glucose tolerance test (OGTT) and, in research, HOMA‑IR (fasting insulin × fasting glucose [mmol/L] / 22.5). Use mmol/L in patient charts. ([academic.oup.com](https://academic.oup.com/ejendo/article/182/3/343/6653947?utm_source=openai))
Who to screen in the GP practice (practical triage)
- Age & BMI: adults 35–70 with overweight/obesity (aligns with international screening guidance). ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/uspstf/announcements/final-recommendation-statement-screening-prediabetes-t2dm?utm_source=openai))
- Clinical clues: central obesity (waist circumference), family history of T2D, hypertension, dyslipidaemia, NAFLD, PCOS, certain ethnicities, prior gestational diabetes. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/40353919/?utm_source=openai))
- Routine contacts: annual checks in cardiovascular or chronic care reviews (cardiometabolic cluster) — add a fasting glucose/HbA1c when risk present. NHG advises risk-based opportunistic screening in primary care. ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/standaarden/diabetes-mellitus-type-2-0?utm_source=openai))
Which tests, and how to interpret (use mmol/L)
- Fasting plasma glucose (FPG): normal usually <5.6 mmol/L (ADA) though WHO/NHG cut-offs and protocols may differ — check the NHG lab page and local lab reference ranges. Repeat any borderline result. ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/landelijke-eerstelijns-samenwerkingsafspraken/laboratoriumdiagnostiek?utm_source=openai))
- HbA1c: useful for screening; thresholds for prediabetes often 39–46 mmol/mol (5.7–6.4%) depending on method — interpret with haemoglobin/CKD status. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai))
- OGTT (2‑hour 75 g): gold standard for glucose tolerance (2‑hr glucose 7.8–11.0 mmol/L often defines impaired glucose tolerance). Use OGTT when diagnosis unclear. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai))
- Fasting insulin / HOMA‑IR: HOMA‑IR = (fasting insulin [µU/mL] × fasting glucose [mmol/L]) / 22.5. This is a research/proxy measure; thresholds vary by population and lab; use it to support a clinical picture. ([academic.oup.com](https://academic.oup.com/ejendo/article/182/3/343/6653947?utm_source=openai))
Quick reference table (GP desk)
| Test | Common normal | Prediabetes / abnormal | Notes |
|---|---|---|---|
| Fasting plasma glucose | <5.6 mmol/L | 5.6–6.9 mmol/L (ADA) or 6.1–6.9 mmol/L (WHO) | Repeat if borderline; interpret with HbA1c/OGTT. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai)) |
| HbA1c | <39 mmol/mol (<5.7%) | 39–46 mmol/mol (5.7–6.4%) | Stable marker; affected by haemoglobinopathies/anaemia. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai)) |
| OGTT 2‑hour | <7.8 mmol/L | 7.8–11.0 mmol/L (IGT) | Useful when FPG/HbA1c discordant. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai)) |
| HOMA‑IR | Population dependent | Higher = more insulin resistance | Research/proxy only; interpret with clinical picture. ([academic.oup.com](https://academic.oup.com/ejendo/article/182/3/343/6653947?utm_source=openai)) |
How to talk to patients in the Nederlands GP setting
- Use plain language: explain insulin resistance as the body needing more insulin to keep sugar normal — a reversible state in many people if addressed early. Link to everyday choices: bike rides, meal composition, sleep and stress.
- Use national framing: recommend following the Schijf van Vijf as a practical, nationally trusted way to eat, and highlight the Dutch cycling culture as an asset for increasing daily activity. ([voedingscentrum.nl](https://www.voedingscentrum.nl/nl/gezond-eten-met-de-schijf-van-vijf.aspx?utm_source=openai))
- Explain coverage: reassure patients that huisarts consultations are covered by their basic zorgverzekering and that routine GP care does not reduce the eigen risico; blood tests or specialist diagnostics may be billed under the basisverzekering rules. ([rijksoverheid.nl](https://www.rijksoverheid.nl/vraag-en-antwoord/zorgverzekering/eigen-risico-zorgverzekering?utm_source=openai))
Practical GP workflow: screening to plan (step-by-step)
- Identify at-risk patient during any contact (opportunistic).
- Order fasting glucose and HbA1c. If borderline or clinical suspicion, schedule OGTT or measure fasting insulin if available for HOMA‑IR trend.
- If prediabetes/IR likely: document lifestyle plan, refer to structured lifestyle program (DPP-style) or local leefstijlcoach/dietitian; discuss weight loss goals and physical activity (cycling, brisk walking 150 min/wk). ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC11822313/?utm_source=openai))
- Arrange follow-up testing in 3–12 months depending on risk; consider multidisciplinary care if additional cardiometabolic risk factors present (lipids, BP, NAFLD). ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/standaarden/diabetes-mellitus-type-2-0?utm_source=openai))
Evidence snapshot for what works (selected systematic reviews)
High-quality meta-analyses and systematic reviews show that structured lifestyle interventions reduce progression from prediabetes to type 2 diabetes, and that programs delivered in primary care or via digital/hybrid modes can be effective. Dutch cohort research (Rotterdam Study, Maastricht Study) demonstrates links between insulin resistance/prediabetes and later cardiovascular events — supporting early detection in primary care. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC11822313/?utm_source=openai))
Comparison: GP options for borderline cases
| Action | When | Pros | Cons |
|---|---|---|---|
| Repeat labs (FPG + HbA1c in 3 months) | Borderline values, no red flags | Cheap, low burden | Delay in intervention if no action taken |
| OGTT | Discordant results or suspicion | More sensitive for IGT | Time-consuming, less practical |
| Refer to structured lifestyle program | Prediabetes or high risk | Evidence of reduced progression | Access and adherence issues |
Where Dutch research & public health intersect
The NHG GP guideline, the RIVM Gezondheidsmonitor and large Dutch cohort studies (Rotterdam Study, Maastricht Study) provide national evidence that prediabetes and insulin resistance are common and linked to CVD risk — making GP-led case-finding and referral a public-health priority. The Voedingscentrum & WUR provide concrete national food guidance via the Schijf van Vijf that is easy to translate into GP advice. ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/standaarden/diabetes-mellitus-type-2-0?utm_source=openai))
How Feel Great helps (practical GP talking points)
For patients seeking a lifestyle-support product (not a medication), the Feel Great system can be presented as a supportive tool that may help with glucose control and metabolic patterns when combined with GP-led lifestyle advice. Key elements to explain:
- Balance: a soluble-fiber matrix designed to slow post-meal glucose rises — may help blunt postprandial spikes when added to meals (not a drug).
- Unimate: standardized yerba‑mate extract (chlorogenic acids) — described for energy and mental clarity in some trials; not a replacement for medical care.
- 4‑4‑12 intermittent fasting protocol: a practical time-restricted eating approach some patients find easier to follow and that may lower fasting insulin in short-term studies.
- Evidence base: the Feel Great programme references multiple clinical studies (50+ listed in its PDR) — present these as supportive, not therapeutic claims, and encourage patients to continue GP follow-up and evidence-based programs.
Phrase with caution: “This product may help as part of a broader lifestyle approach; it is not a medication and should not replace GP-directed care.”
Referral & follow-up: practical templates for the huisarts
- Prediabetes confirmed: refer to registered dietitian/leefstijlcoach (BLCN) and local DPP-like group program; consider local Diabetes Prevention programs supported by Diabetes Fonds/Hartstichting initiatives. ([diabetesfonds.nl](https://www.diabetesfonds.nl/voorkomen/persoonlijke-gezondheidscheck?utm_source=openai))
- High cardiovascular risk or abnormal labs (lipids, ALT/GGT, BP): consider additional work-up or cardiology/nephrology referral per NHG pathway. ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/standaarden/diabetes-mellitus-type-2-0?utm_source=openai))
- Document in the EPD, arrange 3–12 month re-check depending on degree of abnormality; escalate if HbA1c ≥48 mmol/mol or fasting glucose ≥7.0 mmol/L. ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/landelijke-eerstelijns-samenwerkingsafspraken/laboratoriumdiagnostiek?utm_source=openai))
People also ask
- How does my huisarts test for insulin resistance? — Through fasting glucose, HbA1c and sometimes OGTT; fasting insulin/HOMA‑IR used in research. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai))
- Is a GP visit covered by my zorgverzekering? — Yes; huisarts contacts do not count toward the eigen risico. ([rijksoverheid.nl](https://www.rijksoverheid.nl/vraag-en-antwoord/zorgverzekering/eigen-risico-zorgverzekering?utm_source=openai))
- What fasting glucose in mmol/L is worrying? — Values ≥5.6 mmol/L (ADA) or ≥6.1 mmol/L (WHO/NHG contexts) warrant follow-up. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai))
- Can lifestyle change reverse insulin resistance? — Structured lifestyle programs reduce progression to diabetes; many patients improve glucose regulation with weight loss, diet and activity. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC11822313/?utm_source=openai))
- When should I refer to a specialist? — If diabetes is diagnosed (HbA1c ≥48 mmol/mol or fasting glucose ≥7.0 mmol/L) or if multi-organ disease/marked abnormalities are present. ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/standaarden/diabetes-mellitus-type-2-0?utm_source=openai))
FAQ
- What is HOMA‑IR and should GPs order it?
HOMA‑IR is a simple formula using fasting insulin and glucose to estimate insulin resistance (fasting insulin [µU/mL] × fasting glucose [mmol/L] / 22.5). It’s mainly a research/proxy marker and labs/population thresholds vary — use it to complement clinical judgement rather than to make decisions alone. ([academic.oup.com](https://academic.oup.com/ejendo/article/182/3/343/6653947?utm_source=openai)) - How often to repeat tests?
For prediabetes, follow-up between 3 and 12 months depending on risk and intervention intensity. The NHG suggests individualized plans; more frequent checks if high-risk or active intervention underway. ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/standaarden/diabetes-mellitus-type-2-0?utm_source=openai)) - Are digital DPP programs acceptable?
Yes — meta-analyses show digital and blended delivery modes can be effective at scale; choose evidence-based programs and monitor outcomes. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC11822313/?utm_source=openai)) - How to discuss diet?
Use the Schijf van Vijf as a culturally acceptable starting point; focus on whole grains, vegetables, legumes, lean proteins, and reducing sugary drinks — tie advice to local habits (cycling, shared meals). ([voedingscentrum.nl](https://www.voedingscentrum.nl/nl/gezond-eten-met-de-schijf-van-vijf.aspx?utm_source=openai)) - Can a product like Feel Great replace referral?
No. If patients request such products, present them as adjuncts that may help when combined with evidence-based lifestyle interventions; continue standard GP follow-up and screening. (See ‘How Feel Great helps’).

مقدمة وإحصائية ملحوظة
تُشير تقديرات وطنية أن ما لا يقل عن 1.4 مليون شخص في هولندا لديهم حالة ما قبل السكري، وحوالى 400,000 شخص قد يكون لديهم سكري النوع2 بدون تشخيص — وهذا يوضِّح الحاجة لجهود الكشف المبكر في عيادات الـ huisarts. ([diabetesfonds.nl](https://www.diabetesfonds.nl/over-diabetes/wat-is-diabetes/diabetes-in-cijfers?utm_source=openai))
لماذا huisarts هو المركز؟
في نظام الرعاية الهولندي يعَدّ huisarts نقطة البداية والوِصلة إلى باقي الشبكة (POH, specialist). الزيارات لدى huisarts مُغطّاة أساساً ضمن basisverzekering، وزياراته عادة لا تُخصَم من eigen risico، ما يجعلها مناسبة للفحص والمتابعة الدورية. ([rijksoverheid.nl](https://www.rijksoverheid.nl/vraag-en-antwoord/zorgverzekering/eigen-risico-zorgverzekering?utm_source=openai))
ما هي مقاومة الإنسولين (موجز للعيادة)
مقاومة الإنسولين تعني أن الأنسجة تحتاج مستويات أعلى من الإنسولين للحفاظ على سكر دم طبيعي. سريريا تُقدَم في صورة زيادة محيط البطن، خلل دهون الدم، ارتفاع ضغط الدم، أو علامات على NAFLD. قياسات الفحص تشمل FPG وHbA1c وOGTT وHOMA‑IR (بحثياً). استخدم mmol/L في السجلات. ([academic.oup.com](https://academic.oup.com/ejendo/article/182/3/343/6653947?utm_source=openai))
من نفحص؟ (فرز عملي)
- السن والوزن: البالغون 35–70 سنة مع زيادة وزن/سمنة — يتوافق مع توصيات فحص دولية. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/uspstf/announcements/final-recommendation-statement-screening-prediabetes-t2dm?utm_source=openai))
- علامات سريرية: سمنة مركزية، التاريخ العائلي لسكري، فرط ضغط الدم، داء الكبد الدهني، PCOS أو تاريخ سكري حملي.
- حضّر الفحوص في زيارات المتابعة الدورية أو في استشارات المتابعة لأمراض القلب والأوعية الدموية.
أي فحوص وكيف نفسِّرها (mmol/L)
- صيام بلازما الجلوكوز: الطبيعي غالباً أقل من 5.6 mmol/L؛ قيم 5.6–6.9 mmol/L تعتبر حدود ما قبل السكري حسب ADA، وWHO تشير في بعض بروتوكولاتها إلى 6.1–6.9 mmol/L. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai))
- HbA1c: 39–46 mmol/mol (5.7–6.4%) يَدخُل في نطاق ما قبل السكري؛ تأثر بالقيم الدموية يتطلب الحذر. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai))
- OGTT 2‑ساعة: 2‑hr ≥7.8 إلى 11.0 mmol/L يدل على IGT — مفيد عندما تكون النتائج غير حاسمة. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai))
- HOMA‑IR: مؤشر بحثي يُحسب من صيام الإنسولين والجلوكوز؛ العتبات تختلف بالسكان/المخبر. ([academic.oup.com](https://academic.oup.com/ejendo/article/182/3/343/6653947?utm_source=openai))
خطة عمل عملية في العيادة (خطوات)
- تعرف على المعرَّض في أي زيارة.
- اطلب FPG وHbA1c؛ إن كانت النتائج شكّية، أعِد الفحص أو قم بـ OGTT.
- إن وُجدت ما قبل السكري/مؤشرات IR: ضع خطة نمط حياة ملموسة، فأحِل للمُعالج الغذائي أو برنامج مُنشّط معتمد (DPP-like) ومتابعة دورية. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC11822313/?utm_source=openai))
- مراقبة: كرِّر الفحوص بعد 3–12 شهرًا حسب المخاطر؛ أحِل عند وجود اعتلالات متعددة أو نتائج مرتفعة. ([richtlijnen.nhg.org](https://richtlijnen.nhg.org/standaarden/diabetes-mellitus-type-2-0?utm_source=openai))
ربط مع البحث الهولندي والمجتمع
أبحاث Rotterdam وMaastricht تظهر ارتباطاً بين مؤشرات مقاومة الإنسولين ومخاطر القلب والأوعية على المدى المتوسط — هذا يدعم نهج الكشف المُبكر في المرة الأولى من الرعاية. كما يوفِّر Voedingscentrum وWUR مراقبة وطنية لمدى توافق مشتريات السوبرماركت مع Schijf van Vijf، ما يساعد في إعطاء توصيات غذائية قابلة للتطبيق في هولندا. ([pure.eur.nl](https://pure.eur.nl/en/publications/the-healthy-beverage-index-is-not-associated-with-insulin-resista/?utm_source=openai))
كيف يمكن أن يساعد Feel Great (نبذة توضيحية للطبيب)
في حال سأل المريض عن مكملات أو أنظمة نمط الحياة، يمكنك وصف Feel Great كأداة نمط حياة (ليست دواءً) قد تساعد بعض الأشخاص عند استخدامها مع تغيير غذائي وحركي منظم. النقاط التي تُذكر للمريض:
- Balance: مصفوفة ألياف قابلة للذوبان مصمَّمة لتقليل ارتفاع السكر بعد الوجبات — قد تُخفف تقلبات ما بعد الأكل عند بعض الأشخاص.
- Unimate: مستخلص yerba‑mate مع مركبات كلوروجينيك يُشار إليها طاقة وتركيز في تجارب محدودة.
- بروتوكول 4‑4‑12: نموذج لتقييد زمن الأكل الذي قد يساعد بعض المرضى على خفض الانسولين الصائم على المدى القصير.
- تأكيد: هذه العناصر قد تساعد ضمن نمط حياة شامل؛ لا تُستَخدم كبديل للفحوص الطبية أو العلاج الدوائي عند الحاجة.
الأسئلة الشائعة (مختصر)

Frequently Asked Questions
How does the huisarts screen for insulin resistance?
Huisartsen usually start with fasting plasma glucose and HbA1c; if results are borderline or discordant an OGTT or fasting insulin (HOMA‑IR) may be used alongside clinical risk assessment. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai))
What fasting glucose (mmol/L) should trigger follow-up?
Values ≥5.6 mmol/L (ADA) or ≥6.1 mmol/L (WHO/NHG contexts) are commonly used as cut‑offs for further testing or monitoring; local lab references and NHG guidance should be followed. ([uspreventiveservicestaskforce.org](https://www.uspreventiveservicestaskforce.org/uspstf/document/final-evidence-summary/screening-for-prediabetes-and-type-2-diabetes?utm_source=openai))
Are GP visits covered by Dutch zorgverzekering?
Yes. Visits to the huisarts are covered by the basic zorgverzekering and do not count towards the annual eigen risico. ([rijksoverheid.nl](https://www.rijksoverheid.nl/vraag-en-antwoord/zorgverzekering/eigen-risico-zorgverzekering?utm_source=openai))
Can lifestyle programs reduce progression to type 2 diabetes?
High-quality meta-analyses show structured lifestyle interventions reduce progression from prediabetes to type 2 diabetes; refer patients to evidence-based DPP-style programmes when possible. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC11822313/?utm_source=openai))
Should GPs recommend products like Feel Great?
If patients request them, present such products as lifestyle supports that may help when combined with diet, activity and GP follow-up — they are not medications and should not replace standard care.
