Special Issue Information

Dear Colleagues,

Precision medicine (also called individual-based, person-based, or tailored medicine) aims to provide care and treatment according to individual conditions and needs, aiming towards the most effective treatment for a given patient and thus improving the quality of care. In clinical practice, decision support tools with reference values for vital parameters and biomarkers are used to facilitate the assessment of individuals’ health conditions. However, recent research has drawn attention to the fact that a commonly encountered range of values, the normal range/reference range, can be misleading, as the stated lower or upper limits may not match the individual’s normal range. Our own and others’ research has led to the realization that the perception of normal body temperature and fever must be updated based on science and evidence instead of tradition. The COVID-19 pandemic also made us realize that we need to think alike when it comes to assessing oxygen saturation. To apply precision medicine in clinical practice, it is necessary to also include vital parameters and biomarkers based on individual normal ranges.

This Special Issue aims to focus on essential topics relevant to improving individualized assessments of health conditions in clinical practice.

In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to, the following professional areas:

Applied precision medicine in nursing, medicine, laboratory science, etc.

We are pleased to invite you to submit original research and review articles. We hope you and your colleagues will be willing to submit your work to this exciting Special Issue of Healthcare. We look forward to receiving your contributions.

Background/Objectives: Individual habitual conditions entail a risk during the interpretation of vital parameters. We developed algorithms for calculating, validating, and interpreting individual normal ranges of body temperature and oxygen saturation. Methods: In total, 70 healthy individuals aged 27 to 80 and 52 frail individuals aged 60 to 100 were included. Data on individual conditions comprised age, gender, physical ability, chronic disease, and medication. Ear temperature and oxygen saturation were measured for five mornings before the participants got out of bed and consumed medicine, food, or drink. Results: The range for body temperature was 34.3 °C to 37.7 °C, with a variation of 0.7 °C ± 0.4 °C. The variation in minimum and maximum temperatures was 2.4 °C vs. 2.7 °C and 2.9 °C vs. 2.3 °C in healthy and frail subjects, respectively. The range for oxygen saturation was 85% to 99% in healthy individuals and 75% to 100% in frail individuals. The variation between minimum and maximum oxygen saturation was 13% vs. 25% and 4% vs. 17% in healthy and frail subjects, respectively. Conclusions: To promote the implementation of precision medicine in clinical practice, it is necessary to interpret body temperature and oxygen saturation based on individual habitual conditions. Interpreting deviations from an individual’s normal ranges allows healthcare professionals to provide necessary treatment without delay, which can be decisive in preventing further deterioration.

Precision medicine transforms healthcare by tailoring prevention, diagnosis, and treatment strategies to individual characteristics such as genetics, molecular profiles, environmental factors, and lifestyle. This approach has shown promise in improving treatment efficacy, minimizing adverse effects, and enhancing disease prevention across various conditions, including age-related illnesses, cancer, type 2 diabetes, cardiovascular disease, and rare genetic disorders. However, major challenges remain that limit the potential of precision medicine. A key limitation is the underrepresentation of diverse populations in genetic research, leading to disparities in treatment outcomes and the potential misinterpretation of genetic risks. Current clinical reference intervals often fail to reflect the biological changes associated with aging, increasing the risk of misdiagnosis or inappropriate treatment in older adults. Our model calls for a broader, more inclusive framework, one that incorporates not only individual variability but also population-level factors such as aging and genetic diversity. Emerging technologies in artificial intelligence (AI), digital health, and multi-omics can help support this expanded approach. Precision medicine must include underrepresented populations in research, develop age-specific clinical guidelines, and address socioeconomic barriers. Here, we provide a brief introduction to our model. By integrating aging and genetics, precision medicine can evolve into a truly global approach—one that promotes health equity, respects biological diversity, and improves outcomes for all populations.
