Clinical questions frequently form natural clusters – variations on a theme that together reveal a richer, more connected picture of evidence. For example, questions about TSH and lifestyle might include sleep, exercise, diet, stress, and psychosocial factors – each distinct, yet interrelated.

One approach we’re exploring to capture these connections is cluster reviews – analyses that group related clinical questions to uncover overarching patterns in evidence and practice. These reviews would take a bottom-up approach, grounded in real clinical questions asked by health professionals. Unlike traditional top-down reviews that begin with predefined topics or published frameworks, cluster reviews are shaped by the real-world information needs that emerge in clinical settings, offering a practice-driven view of the evidence landscape.

We’re experimenting with an interactive cluster review that brings these related Q&As together into a single, navigable experience. It allows clinicians, researchers, and learners to see how different lifestyle and psychosocial factors intersect, and to identify where evidence is thin or emerging.

The goal is to make evidence engagement interactive, modular, and cumulative – each review builds on previous answers, creating a living, evolving knowledge map rather than static summaries.

You can explore the first prototype, Lifestyle, Psychosocial, and Behavioral Influences on TSH Levels, through the interactive review – and we welcome your feedback on how this could best support your evidence needs. And, to be clear, this is a simple prototype, if we go ahead with this we would work hard to make the design wonderful 🙂

AskTrip has just reached a remarkable milestone – 5,000 clinical questions answered in under 20 weeks. On its own, that’s an impressive figure. But the real story lies in the contrast with our early work and what this achievement represents for evidence-based healthcare.

From Manual Q&A to the Digital Frontier

Back in 1997, we launched ATTRACT, one of the world’s first evidence-based Q&A services for clinicians. It was followed by the National Library for Health Q&A service – both pioneering efforts, the latter ran until around 2012.

Across those 15 years, our teams of information specialists and clinicians answered around 10,000 clinical questions. Each one required 4–6 hours of careful searching, appraisal, and synthesis – a manual, time-intensive process, but one that had a huge impact on clinical decision-making.

Those services were driven by a simple belief: that busy clinicians should have quick, trusted access to the best available evidence to inform patient care. That belief remains unchanged today.

Trip’s Core Mission: Connecting Clinicians with Evidence

The Trip Database was originally created to support the work of ATTRACT, providing rapid access to high-quality evidence for the team answering clinical questions. Over time, it became clear that Trip could serve a much wider audience – helping clinicians everywhere find reliable evidence efficiently.

From those early days, Trip has always been about one thing: connecting clinical decision-makers with the best available evidence.

Over the years, it has evolved from a focused evidence search tool into a comprehensive evidence ecosystem, helping millions of users around the world find trustworthy answers faster. AskTrip is the latest, and perhaps most exciting, chapter in that ongoing story.

AskTrip: A Natural Extension of Trip’s Mission

AskTrip builds directly on Trip’s foundations but uses a radically different interface – natural language. Clinicians can now simply type a question such as “What’s the best treatment for resistant hypertension in pregnancy?” and receive a clear, concise, evidence-based summary in seconds.

What previously took hours or days of searching can now be achieved almost instantly. Yet the principles that underpin AskTrip are the same as ever: reliability, transparency, and a commitment to evidence, not opinion.

AskTrip doesn’t replace human judgment or the careful reading of full studies – it amplifies access to trusted information when it’s needed most.

A Shift in Scale

The numbers tell the story:

• 10,000 Q&As in 15 years through manual services like ATTRACT and the NLH Q&A service.
• 5,000 Q&As in less than 20 weeks through AskTrip.

That’s not just efficiency – it’s accessibility at scale. Thousands of clinicians have been able to get quick, high-quality answers to their clinical questions, helping improve decision-making in real-world settings.

Looking Ahead

This milestone is more than a statistic; it’s a reflection of how far evidence-based medicine has come – and how technology can help accelerate it without compromising quality.

AskTrip represents the next step in a journey that began nearly three decades ago. The tools may have changed, but the mission remains constant: to connect clinical decision-makers with the best available evidence, as quickly and clearly as possible.

We’re incredibly proud of how far we’ve come – and even more excited about what lies ahead.

We’re excited to share an important update to AskTrip – not quite a version 2, but definitely a strong v1.5. This upgrade builds on what’s working well, while tackling some of the challenges we’ve seen since launch. The result: better answers, more trustworthy evidence, and less noise.

What’s New?

1. More Evidence, More Coverage

AskTrip now considers a wider pool of articles when building answers. This means you’ll benefit from a broader sweep of relevant studies, ensuring that useful evidence doesn’t get missed.

2. Smarter Evidence Extraction

We’ve upgraded both the prompts and the large language model behind AskTrip. These improvements sharpen how the system extracts evidence from research, cutting through complexity to surface the insights that matter.

The payoff? More accurate answers and fewer hallucinations.

3. Improved Quality Scoring

Our enhanced quality score system better balances study design, recency, and relevance. That means you’ll see more reliable evidence, ranked in a way that helps you judge its strength quickly and confidently.

4. Beyond Trip: Smarter Sourcing

Sometimes the evidence available in Trip isn’t enough. With this update, AskTrip automatically extends the search to Google Scholar and OpenAlex when needed – giving you access to a wider world of research without leaving the platform.

Why This Matters

Every improvement we make to AskTrip is guided by one principle: helping health professionals make faster, better-informed decisions. With v1.5, you’ll get answers that are broader in scope, more accurate, and underpinned by higher-quality evidence.

We’ll continue refining AskTrip in response to your feedback, so please keep letting us know what works and where we can improve.

En AskTrip, nuestro objetivo es hacer que la evidencia de alta calidad sea accesible para los profesionales de la salud en todo el mundo, sin importar el idioma. Para nuestros usuarios hispanohablantes, esto significa que traducimos su pregunta al inglés, la procesamos en el sistema de AskTrip y luego traducimos la respuesta nuevamente al español.

Recientemente descubrimos un problema en la forma en que se gestionaban las preguntas en español dentro de AskTrip. Esto ocasionaba dos situaciones principales:

1. La pregunta aparecía en español, pero la respuesta se mostraba en inglés.
2. Tanto la pregunta como la respuesta aparecían en español, pero los términos de búsqueda también se procesaban en español.

El segundo caso era especialmente problemático. Dado que la base de evidencia de Trip está en inglés, realizar búsquedas en español devolvía pocos resultados o, en muchos casos, resultados de muy baja calidad.

Durante el fin de semana implementamos una solución y, desde entonces, no hemos detectado más casos de este problema. Confiamos en que ha quedado resuelto.

Queremos disculparnos sinceramente con nuestros usuarios de habla hispana por esta incidencia. A partir de ahora, deberían notar una clara mejora en la calidad y coherencia de su experiencia en AskTrip.

English Translation: An Apology to Our Spanish-Language Users of AskTrip

At AskTrip, we aim to make high-quality evidence accessible to health professionals worldwide, regardless of language. For our Spanish-speaking users, this means we translate your question into English, process it through the AskTrip system, and then translate the answer back into Spanish.

Recently, we discovered an issue in how Spanish questions were handled within AskTrip. This led to two main problems:

1. The question appeared in Spanish, but the answer was displayed in English.
2. Both the question and the answer were in Spanish, but the search terms were also processed in Spanish.

The second issue was especially problematic. Since Trip’s evidence base is in English, running searches in Spanish returned little – or in many cases, poor – results.

We implemented a fix over the weekend, and since then we’ve seen no further cases of the problem. We’re confident it’s resolved.

We sincerely apologise to our Spanish-language users for this disruption. From now on, you should notice a clear improvement in the quality and consistency of your AskTrip experience.

Sometimes the best answer isn’t within Trip’s core collection. That’s why we’ve introduced Beyond Trip, a new feature designed to broaden the search and deliver stronger, more reliable answers when evidence is limited.

How It Works

Beyond Trip is automatically triggered when AskTrip produces an answer that’s judged to be poor:

• Limited answers, or
• Moderate answers with three or fewer references.

When this happens, AskTrip seamlessly expands the search to Google Scholar and OpenAlex, scanning the wider research landscape for additional evidence.

You don’t need to take any action – the process happens automatically. It adds about 20–30 seconds to generating the answer.

What You’ll See

New answers created through this process are clearly labelled as having used Beyond Trip.

Two outcomes are possible:

1. A stronger answer: If new evidence is found, the revised response will be presented with its expanded reference base. You’ll see a note confirming that the answer has utilised Beyond Trip.
2. A genuine evidence gap: If evidence remains poor, we’ll highlight that even after Beyond Trip, good-quality evidence could not be found. In these cases, we’ll offer five broader or related searches you can try, helping you explore areas where stronger evidence may exist.

Why It Matters

In testing, results have ranged from no change (confirming a genuine lack of evidence) to major improvements – for example, an answer going from zero references in the original output to six references after Beyond Trip.

By intelligently expanding the search only when needed, Beyond Trip ensures you’re not just getting an answer – you’re getting the best possible evidence available.

A nursing friend recently asked me about the types of questions we’re receiving from nurses via AskTrip. Since we don’t record the profession of everyone who submits a question, I can’t say exactly what nurses are asking. What I could do, however, was analyse the 40 questions that directly focused on nursing – a reasonable sample to identify patterns. And 4 themes emerged:

Clinical Practice & Patient Care
This theme captures the heart of nursing – the direct application of skill and evidence to improve patient outcomes. The questions reveal a profession dedicated to continuous quality improvement and safety, seeking out evidence-based practices (EBP) in everything from preventing infections like CLABSIs to the simple act of bathing in a nursing home. There is a strong focus on highly specialised areas (e.g., managing chest drains in neonates after cardiac surgery, providing palliative care education), and a push to empower patients, such as assessing the competence of diabetic patients to self-manage. Ultimately, this theme is about defining and standardising the best possible care across all clinical settings, from the Emergency Department (ED) to the community.

Example questions:

• What are some nurse-driven evidence-based projects by nurses?
• How can nurses care for and manage chest drains in babies following cardiac surgery?

Nursing Roles & Specialisation
Nursing is no longer a one-size-fits-all profession! These questions underscore the dramatic specialisation and diversification occurring within the field. From comparing the functions of a State Diploma Coordinator Nurse versus an Advanced Practice Nurse (APN) in oncology, to understanding the implementation experiences of APNs, nurses are constantly negotiating their scope of practice. The demand for specialist roles – like the Frailty Nurse Specialist who optimises patient flow, or the Head and Neck Cancer Nurse Specialist – shows that hospitals rely on nurses to manage complex patient pathways and drive efficient, coordinated care. This theme explores how nurses are elevating their professional role to meet sophisticated healthcare demands.

Example questions:

• What are the roles or functions of a State Diploma Coordinator Nurse versus an Advanced Practice Nurse in oncology?
• What is the role of a frailty nurse specialist in front-door assessment, admission avoidance, safe discharge planning, and the implementation of least restrictive options in acute care settings?

Education & Professional Development
This grouping dives into how the next generation of nurses is trained, supported, and nurtured. It’s not just about skills; there is a deep academic interest in how nurses acquire professional virtues – the ethical and moral compass – which is fundamental to the profession. Practically, the questions stress the importance of effective teaching and mentorship, focusing on tools like preceptor feedback instruments to improve communication on placement and the use of ePortfolios to support student learning. Whether it’s through innovative continuous professional development (CPD) methods like “Tea-Trolley Teaching” or formalised annual competencies, this theme highlights the commitment to ensuring all nurses remain highly skilled and ethically grounded throughout their careers.

Example questions:

• How do nurses acquire, develop, or learn virtues for practice?
• Are there preceptor feedback tools that facilitate communication between preceptors and preceptees to improve nursing academic outcomes?

Workforce, Organisation & Policy
The final theme addresses the crucial, high-level issues impacting the sustainability and health of the nursing workforce. Questions here center on policy and operational efficiency, including the search for safe staffing ratios and frameworks, particularly in high-demand areas like the ED. The profession is actively tackling burnout and retention by seeking organisational interventions to support new nurses. Furthermore, the interest in creating nursing float pools speaks to the need for flexible, effective staffing solutions. This theme encompasses the external factors that influence the profession, including the impact of social media portrayal on public perception and recruitment, making it a critical area for leadership and policy reform.

Example questions:

• What is the evidence base for safe nursing staffing in emergency departments internationally?
• What organisational interventions have been used to reduce burnout and increase retention in new nurses?

Taken together, these 40 questions paint a picture of a profession that is dynamic, diverse, and deeply committed to improvement. Nurses are seeking evidence not only to refine clinical practice at the bedside, but also to expand their roles, strengthen education and professional development, and influence the policies that shape their working lives. The themes suggest a workforce that is both responsive to today’s challenges and actively shaping the future of healthcare.

With nearly 3,700 questions answered, we’ve gained a wealth of learning. From the very beginning, we’ve closely tracked both the questions and the answers, giving us valuable insights into the system’s strengths and areas for improvement.

Behind the scenes, we’ve been working on a major upgrade (our “v2”), which is now in testing. The key enhancements include:

• Improved search: A new approach that strengthens the link between a user’s question and the articles we identify, ensuring more relevant candidates are surfaced.
• Greater coverage: A more sensitive system that draws on a wider range of articles identified through the improved search.
• Reduced hallucinations: Specific safeguards to minimise inaccurate or invented content.
• Beyond Trip: If evidence is scarce in Trip, the search will automatically expand into the broader academic literature [learn more here].
• Answer scoring: A more refined and nuanced way of rating responses.

Each of these features has been tested individually, and we’ll soon begin testing them together as an integrated system. We’re optimistic these changes will deliver a step change in performance.

And, a final comment, we’re already working on v2.1…

Every day, health professionals grapple with countless clinical questions. Some are straightforward, with clear answers found in guidelines or textbooks. Others spark debate, inspire curiosity, and feel worth sharing. But what makes one question stand out as more “interesting” than another?

At AskTrip, we’ve spent a lot of time thinking about this. For us, an “interesting” clinical question isn’t simply unusual — it’s one that resonates with professionals because it touches on the realities of care, challenges assumptions, or sheds light on evolving areas of medicine.

To bring some structure to this, we’ve developed a scoring system. It looks at elements such as:

• Clinical impact — will the answer meaningfully affect decisions or outcomes?
• Breadth — is it relevant across specialties or patient groups?
• Uncertainty or controversy — are there conflicting views or evolving evidence?
• Novelty and timeliness — does it involve new drugs, recent guidelines, or emerging issues?
• Complexity and nuance — does it require careful reasoning beyond the obvious?

Each question is scored across these dimensions (maximum score = 5). Here are some examples:

• What is the impact of homelessness on diabetes management and outcomes? → 4.1
  Broad relevance, strong evidence base, significant clinical and policy impact.
• Are there specific guidelines or recommendations for cannabis use during pregnancy from major health organizations? → 4.1
  Timely, controversial, and highly relevant to everyday practice.
• How can sarcopenia be prevented after treatment with semaglutide? → 4.0
  A novel question linked to one of the hottest areas in medicine.
• Best management for a first pregnancy at 26 weeks with cervical length of 1.2 cm? → 3.7
  High clinical impact, clear practical stakes, though narrower in breadth.
• Are two HbA1c tests diagnostic of diabetes even if conducted years apart? → 3.6
  Practical and relevant to many clinicians, with some guideline nuance.
• What are the current recommended treatments for Taenia saginata infection? → 2.6
  Important in context, but largely settled with little controversy or novelty.
• Can Zactin affect sleep? → 2.3
  Very narrow and duplicative of existing fluoxetine-related evidence.

As these results show, the most interesting questions tend to blend impact, breadth, and uncertainty, while also tapping into novelty or a strong curiosity hook. These are the ones that spark debate, inspire teaching moments, and make clinicians pause to think differently about care.

At AskTrip, we’re building this scoring into our platform, so health professionals can quickly discover the questions most likely to provoke insight, debate, and better decision-making. After all, the right question is often the first step toward the right answer.

One of the most fascinating aspects of running clinical Q&A services is seeing what questions clinicians actually ask. Looking back at questions submitted to the UK primary care Q&A services – ATTRACT in Wales and the NLH Q&A Service in England (both ended by early 2010s)- and comparing them with questions submitted to AskTrip (from 2025 onwards) gives us a rare opportunity to see how frontline clinical uncertainty has evolved over two decades.

There’s an important distinction: ATTRACT and NLH Q&A were exclusively used by primary care clinicians, while AskTrip has always had a broader, less clearly defined user base. This makes the comparison even more interesting: we’re contrasting the firmly primary care questions of the 2000s with a more mixed set of modern-day queries.

For this analysis, we focused on four common clinical areas: asthma, hypertension, depression, and diabetes. We identified relevant questions from AskTrip, then selected a matching set of questions from the historical ATTRACT/NLH archives. To give balance, we used the same number of questions for each condition across both sources. This approach doesn’t capture every question ever asked, but it provides a structured way to compare themes and see how the nature of clinical uncertainty has shifted over time.

---

Asthma: Same Worries, New Tools

• Then (ATTRACT & NLH Q&A): Questions often focused on inhalers and safety: Should LABAs always be combined with steroids? Does tiotropium help in asthma? Is chlorine in swimming pools a trigger for atopic kids? These were very patient-specific, case-driven questions.
• Now (AskTrip): Questions reflect newer therapies and broader patient groups: When should biologics be started? What’s the role of immunotherapy? How do you manage asthma in pregnancy or elite athletes?

The safety theme is consistent, but modern queries also ask about biologics, prevention, and life stages – reflecting advances in care and broader evidence.

---

Hypertension: From Protocols to Personalisation

• Then: Practical queries dominated: How often should hypertensives have bloods checked? Which drugs are safe in pregnancy? These questions often referenced NICE guidelines or practical case scenarios.
• Now: Broader and more diverse: What’s the best treatment for hypertension? Is renal denervation worth considering? What’s the malpractice risk of hypertension?

We’ve moved from nuts-and-bolts case management to personalised medicine (pharmacogenetics), lifestyle interventions, digital tools, and even system-level concerns.

---

Depression: Beyond Antidepressants

• Then: Most questions were about drugs and safety: long-term use of dosulepin, SSRI interactions, depression risk from antihypertensives, safe prescribing in pregnancy, and whether statins cause low mood.
• Now: The scope has widened: How effective is CBT vs medication? What about ketamine or esketamine for resistant depression? Does partner involvement help postnatal depression? Is St John’s Wort useful?

Clinicians still worry about safety, but there’s now far greater interest in therapy modalities, novel treatments, and patient-centred care.

---

Diabetes: Core Concerns, Expanding Horizons

• Then: Focused on early prevention debates and older drugs: Is aspirin useful for primary prevention? Metformin vs sulfonylurea first-line? How much does each drug lower HbA1c? When to stop metformin in renal impairment?
• Now: Questions reflect a complex therapeutic landscape: What’s the role of GLP-1s, SGLT2s, tirzepatide? How effective are lifestyle interventions in preventing diabetes? Is AI ready for diabetic retinopathy screening? Should podiatrists be embedded in primary care teams?

The fundamentals (glycaemic control, complication prevention) remain, but questions now incorporate new drug classes, technology, prevention strategies, and system-level solutions.

---

Cross-Cutting Themes

Looking across all four areas, some common threads emerge:

1. “What’s the best treatment?” never goes away. Whether in 2005 or 2025, clinicians want to know the most effective, safest option.
2. Safety is a constant. Every era has questions about drug harms, interactions, and risks in special populations.
3. Shifts in framing. The early services captured questions often phrased as case vignettes; AskTrip includes both detailed scenarios and broad, almost textbook-like questions.
4. Lifestyle and holistic care. Far more visible in modern questions – from mindfulness to diet, fasting, exercise, and patient communication.
5. Technology and innovation. Biologics, pharmacogenetics, AI, apps, and new drug classes appear only in the newer questions.
6. From patient to system. Modern queries also touch on malpractice, prevalence in specific countries, and team-based care.

---

Conclusion

Comparing two decades of clinical questions is like holding up a mirror to how medicine itself has changed. The essence of what clinicians want – safe, effective treatments backed by evidence – has never shifted. But the tools, therapies, and perspectives have expanded dramatically.

ATTRACT and the NLH Q&A Service captured the day-to-day dilemmas of UK primary care in the 2000s, while AskTrip reflects a wider, global audience with questions ranging from basic management to cutting-edge therapies and system-level challenges.

In 2005, a GP in Wales might have been asking whether to taper clonidine slowly; in 2025, someone on AskTrip is asking whether AI is ready to screen for diabetic retinopathy. The questions evolve, but the clinician’s need for trustworthy, evidence-based answers remains constant.
