Best Open Source Healthcare Datasets for Machine Learning Projects

• The global healthcare system produces vast amounts of medical data on a daily basis, which has the potential to be utilized for machine learning applications. Across all industries, data is regarded as a precious asset that enables companies to gain a competitive edge, and the healthcare sector is no different.

This article will concisely address the obstacles encountered when dealing with medical data and provide a summary of publicly accessible healthcare datasets.

Importance of Healthcare Datasets

Healthcare datasets are collections of patient information, such as medical records, diagnoses, treatments, genetic data, and lifestyle details. They are very important in today’s world, where AI is used more and more. Here’s why:

Understanding Patient Health:

Healthcare datasets give doctors a full picture of a patient’s health. For example, data about a patient’s medical history, medicines, and lifestyle can help predict if they might get a chronic disease. This lets doctors step in early and make a treatment plan just for that patient.

Helping Medical Research:

By studying healthcare datasets, medical researchers can look at how cancer patients are treated and how they recover. They can find the treatments that work best in the real world. For example, by looking at tumor samples in biobanks and patient treatment histories, researchers can learn how specific mutations and cancer proteins react to different treatments. This data-driven approach helps find trends that lead to better patient outcomes.

Better Diagnosis and Treatment:

Doctors use AI tools to look at healthcare datasets and find important patterns. This helps them diagnose and treat illnesses better. In radiology, AI can find problems in scans faster and more accurately than humans. This means doctors can find diseases sooner and start the right treatment earlier. Medical image annotation can lead to quicker and better diagnosis, which improves patient health.

Helping Public Health Initiatives:

Imagine a small town where healthcare experts used datasets to track a flu outbreak. They looked at patterns and found the areas that were affected. With this data, they started targeted vaccination drives and health education campaigns. This data-driven approach helped contain the flu. It shows how healthcare datasets can actively guide and improve public health initiatives.

Open Source Medical Datasets for Machine Learning

Open datasets are essential for any machine learning model to work well. Machine learning is already being used in life science, healthcare, and medicine, and it’s showing great results. It’s helping predict diseases and understand how they spread. Machine learning is also giving ideas on how we can properly take care of sick, elderly, and unwell people in a community. Without good datasets, these machine learning models wouldn’t be possible.

General and Public Health:

• data.gov: Focuses on US-oriented healthcare data that can be easily searched using multiple parameters. The datasets are designed to enhance the well-being of individuals residing in the US; however, the information could also prove beneficial for other training sets in research or additional public health domains.
• WHO: Offers datasets centered around global health priorities. The platform incorporates a user-friendly search function and provides valuable insights alongside the datasets for a comprehensive understanding of the topics at hand.
• Re3Data: Offers data spanning more than 2,000 research subjects categorized into several broad areas. While not all datasets are freely accessible, the platform clearly indicates the structure and allows for easy searching based on factors such as fees, membership requirements, and copyright restrictions.
• Human Mortality Database offers access to data on mortality rates, population figures, and various health and demographic statistics for 35 nations.
• CHDS: The Child Health and Development Studies datasets aim to investigate the intergenerational transmission of disease and health. It encompasses datasets for researching not only genomic expression but also the influence of social, environmental, and cultural factors on disease and health.
• Merck Molecular Activity Challenge: Presents datasets designed to promote the application of machine learning in drug discovery by simulating the potential interactions between various molecule combinations.
• 1000 Genomes Project: Contains sequencing data from 2,500 individuals across 26 different populations, making it one of the largest accessible genome repositories. This international collaboration can be accessed through AWS. (Note that grants are available for genome projects.)

Image Datasets for Life Sciences, Healthcare and Medicine:

• Open Neuro: As a free and open platform, OpenNeuro shares a wide array of medical images, including MRI, MEG, EEG, iEEG, ECoG, ASL, and PET data. With 563 medical datasets covering 19,187 participants, it serves as an invaluable resource for researchers and healthcare professionals.
• Oasis: Originating from the Open Access Series of Imaging Studies (OASIS), this dataset strives to provide neuroimaging data to the public free of charge for the benefit of the scientific community. It encompasses 1,098 subjects across 2,168 MR sessions and 1,608 PET sessions, offering a wealth of information for researchers.
• Alzheimer’s Disease Neuroimaging Initiative: The Alzheimer’s Disease Neuroimaging Initiative (ADNI) showcases data collected by researchers worldwide who are dedicated to defining the progression of Alzheimer’s disease. The dataset includes a comprehensive collection of MRI and PET images, genetic information, cognitive tests, and CSF and blood biomarkers, facilitating a multifaceted approach to understanding this complex condition.

Hospital Datasets:

• Provider Data Catalog: Access and download comprehensive provider datasets in areas including dialysis facilities, physician practices, home health services, hospice care, hospitals, inpatient rehabilitation, long-term care hospitals, nursing homes with rehabilitation services, physician office visit costs, and supplier directories.
• Healthcare Cost and Utilization Project (HCUP): This comprehensive, nationwide database was created to identify, track, and analyze national trends in healthcare utilization, access, charges, quality, and outcomes. Each medical dataset within HCUP contains encounter-level information on all patient stays, emergency department visits, and ambulatory surgeries in US hospitals, providing a wealth of data for researchers and policymakers.
• MIMIC Critical Care Database: Developed by MIT for the purposes of Computational Physiology, this openly available medical dataset comprises de-identified health data from over 40,000 critical care patients. The MIMIC dataset serves as a valuable resource for researchers studying critical care and developing new computational methods.

Cancer Datasets:

• CT Medical Images: Designed to facilitate alternative methods for examining trends in CT image data, this dataset features CT scans of cancer patients, focusing on factors such as contrast, modality, and patient age. Researchers can leverage this data to develop new imaging techniques and analyze patterns in cancer diagnosis and treatment.
• International Collaboration on Cancer Reporting (ICCR): The medical datasets within the ICCR have been developed and provided to promote an evidence-based approach to cancer reporting worldwide. By standardizing cancer reporting, the ICCR aims to improve the quality and comparability of cancer data across institutions and countries.
• SEER Cancer Incidence: Provided by the US government, this cancer data is segmented using basic demographic distinctions such as race, gender, and age. The SEER dataset allows researchers to investigate cancer incidence and survival rates across different population subgroups, informing public health initiatives and research priorities.
• Lung Cancer Data Set: This free dataset features information on lung cancer cases dating back to 1995. Researchers can use this data to study long-term trends in lung cancer incidence, treatment, and outcomes, as well as to develop new diagnostic and prognostic tools.
