Personalized Medicine: Tailoring Treatment for Individual Health Needs
3 min readPersonalized medicine is founded on the idea that each individual possesses unique genetic, environmental, and behavioral characteristics. Modern biomedical technologies such as DNA sequencing, proteomics and wireless monitoring devices have revealed substantial inter-individual variation in disease processes.
Recognizing these distinct disease characteristics may enable clinicians to design tailored medications that can effectively treat and even prevent diseases.
Personalized Medicine
Personalized medicine is an emerging medical model that places individuals into groups based on predicted responses or risks of disease, tailoring practices, interventions and/or products accordingly to each group based on its responses or risks of disease. It offers promising results while simultaneously decreasing costs.
Most current medical treatments are tailored towards an “average” person; however, each individual differs significantly in terms of genetics, environment and lifestyle factors that dictate treatment decisions. Therefore, personalized medicine offers such great promise as it caters specifically to each person.
For instance, if a mutation in your B-raf gene causes cells to grow unchecked, doctors can detect this mutation and recommend screening as well as monoclonal antibodies which inhibit it and prevent cancerous cell development – this approach increases efficacy of treatment as well as increases survival rates significantly.
However, personalized medicine faces several barriers which must be overcome in order to be implemented successfully – these include intellectual property rights, reimbursement policies, privacy issues and data biases.
Predictive Modeling
Predictive modeling is a powerful tool used by healthcare professionals to analyze complex patterns and anticipate future outcomes. It enables them to detect potential disease outbreaks more rapidly, improve efficiency, and provide superior patient care.
Predictive analytics can provide valuable assistance when patients of a certain age and medical history present with new conditions, by finding those in their population cohort who share similar profiles and suggesting treatment plans that physicians can then apply to individual patient care.
Health systems can use predictive models to identify patients at high risk for readmission and provide preventative interventions, which helps decrease hospital readmission rates that often have detrimental impacts on both their health and finances. Accuracy depends on data quality and consistency; improving data collection and standardization is therefore paramount, and interpretable predictive models must allow physicians to make informed decisions based on accurate results of predictive models.
Biomarkers
Biomarkers are indicators or signposts that help healthcare professionals determine the appropriate treatment strategy for an individual patient. Biomarkers could include proteins, genes, hormones, specific cellular structures or even general biological changes – with body temperature, cholesterol levels and blood pressure being common indicators used as biomarkers of health or disease states.
Biomarkers form the backbone of patient stratification. Biomarkers allow healthcare providers to create highly targeted interventions which can drastically improve outcomes for individuals suffering from various health conditions, without resorting to costly and ineffective trial and error methods.
Patient stratification is at the core of personalized medicine. But this new approach to healthcare requires robust yet flexible regulations that balance innovation with individual privacy concerns – otherwise personalized treatments will likely remain just a dream and/or their implementation may prove too expensive for many individuals.
Targeted Therapy
Personalized medicine utilizes targeted therapy to address specific groups of patients suffering from diseases, using knowledge of genes and proteins associated with said conditions to customize treatments to each group and reduce side effects while improving treatment efficacy and improving treatment effectiveness. This approach has proven highly successful over time.
Targeted therapies account for one third of new drug approvals over the past four years. These medicines target specific patient groups such as those living with cancer or genetic diseases.
Physicians typically employ an iterative trial-and-error process until they discover the ideal therapy regimen for each of their patients, but personalized medicine offers greater accuracy and efficacy in this regard.
Numerous respondents noted that the data collection required by personalized medicine could raise ethical concerns related to privacy and misuse, particularly for EHR systems where health-related data can easily be shared outside the medical community.
