Need GPC data for your next project? GPC data is accessible to bona fide researchers. We make it easy: 📍Review available datasets 📍Submit a short concept note 📍Connect with our data access committee Get started here: lshtm.ac.uk/research/centres… #OpenScience #AfricaDataHub #PopulationHealth #MRCUganda #LongitudinalData

From HIV to non-communicable diseases, ageing, and social determinants of health, work at the GPC isn’t static. With robust data spanning health, behaviour, and environment, our work informs both science and policy. Curious about what we’re exploring now? Dive in: lshtm.ac.uk/research/centres… #PopulationHealth #MRCUganda #LongitudinalData

Ever heard of the General Population Cohort (GPC)? Based in rural southwestern Uganda, the GPC is one of Africa’s richest long-term population health resources, tracking data for over 35 years. More than just another dataset, it’s a window into how health, society, and systems evolve and adapt over time.

Introducing TIMER⌛️: a temporal instruction modeling and evaluation framework for longitudinal clinical records! 🏥📈 TIMER tackles challenges in processing longitudinal medical records—including temporal reasoning, multi-visit synthesis, and patient trajectory analysis. It introduces: 🔹 Time-aware benchmarks to evaluate temporal reasoning abilities 🔹 Temporal instruction tuning for enhanced longitudinal understanding 🔹 Distribution-aware training strategies for balanced temporal coverage Featured Highlights 💡 🔍 TIMER-Bench: First benchmark specifically designed to evaluate temporal reasoning across longitudinal EHRs with explicit datetime grounding for each instruction-response pair 🧩 TIMER-Instruct: Temporal instruction tuning methodology that improves models' ability to reason across patient timelines ⏱️ Multi-timepoint reasoning capabilities—enabling synthesis across different parts of long contexts in the patient records 📋 The "lost-in-the-middle" phenomenon of model-generated instruction response pairs given long-context input—models naturally focus on timeline edges while overlooking critical middle periods 🔬 Three temporal distribution strategies for comprehensive evaluation: recency-focused, edge-focused, and uniformly distributed 📊 Performance: TIMER achieves improvements on clinical benchmarks: 📈 7.3% improvement on physician-generated MedAlign benchmark 📈 9.2% improvement on temporal reasoning on TIMER-Bench 📊 Robust performance with uniformly distributed instruction tuning 🌟 Why TIMER matters: 1️⃣ Physicians routinely analyze EHRs spanning years and thousands of entries 2️⃣ Clinical decisions require understanding complex relationships across time periods 3️⃣ Existing medical LLM benchmarks focus on static QAs, leading to longitudinal evaluation gaps 4️⃣ TIMER bridges these gaps with temporal reasoning capabilities 📄 Read our paper: arxiv.org/abs/2503.04176 👥 Huge thanks to my many collaborators on this project, including @AlyssaUnell, @chenbowen118, @jasonafries, @Emily_Alsentzer, @sanmikoyejo, @drnigam, as well as feedback from the teams at @stai_research and the Shah Lab. #LLMs #TemporalReasoning #LongitudinalData #HealthcareAI

Participants on @OfficialUoM's Introduction to Longitudinal Data Analysis course will learn how to clean and analyse #LongitudinalData. Dr Alexandru Cernat (@cernat_a ) of @SocialStatsMan will lead the five-day course (13 March-11 April). Register: ncrm.ac.uk/training/show.php…

Mixed models are crucial for country-level research: they handle missing data, manage temporal correlations, address unbalanced datasets, and model heterogeneity. My latest article compares inequalities across OECD countries using this method: doi.org/10.1163/15691330-bja… #LongitudinalData

In my research on longitudinal data spanning two decades across 27 countries, the Mixed Model for Repeated Measures showed exceptional adaptability, robustness, and effectiveness in managing missing data. #LongitudinalData #MixedModel brill.com/view/journals/coso…
