Introduction:
Precision medicine is an innovative approach to medical treatment
that considers individual differences in patients genes , environments
and lifestyles. It aims to tailor healthcare interventions to the specific
characteristics of each person, instead of one size fits all approach to
provide more effective and personalized treatments. This involves
utilizing genetic information, bio markers and advanced technologies
for better understanding of the unique aspects of a patient's condition
and improving diagnostic accuracy and treatment effectiveness.

Precision medicine promises to enhance patient outcomes and
minimise adverse effects buy customising healthcare strategies based
on individual variation.
Predictive analytics is the use of data, statistical algorithms and
machine learning techniques to identify the likelihood of future
outcomes based on historical data.

Background:
The key concept of Precision medicine is to develop
drug that focuses on employing biomarkers to stratify
patients in clinical trials with the goal of improving
efficacy and safety outcomes, ultimately increasing
the odds of clinical success and drug approval.

Machine learning in Precision medicine can be defined as
method to identify phenotypes of patients with less common
responses to treatment or unique healthcare needs. These
are meant for patients with presumed or diagnosed rare
genetic disorder. Here large data sets such as genomic,
clinical and other molecular information is analysed to
identify patterns and relationships.
Predictive analytics in patient specific treatment can
enhance healthcare by tailoring interventions to individual
needs, optimising resource allocation, reducting truakials
and error in treatments and improving overall patient
outcomes.

 Data Complexity : Precision medicine deals with diverse and complex data type,
posing challenges in integrating and analyzing such heterogeneous information.
 Small sample size: Limited patient datasets in case of rare disease hinder the
development of robust predictive models, leading to the lack of generalizability.
 Interpatient Variation: Every individual response differently to the treatment
hence creating universal applicable models is a challenging task.
CHALLENGES:

 Ethical and privacy Concerns : Handling sensitive patient data requires strict
privacy measures, creating barriers to accessing large datasets for model training.
 Regulatory compliance: Meeting regulatory standards for the deployment of
machine learning models in healthcare settings such as FDA approval makes the
development process more complex.
 Incompleteness: The accuracy of predictive analytics models is limited by the
completeness and accuracy of the data being used. As the analytical algorithms
build models based on the available data, deficiency in the data may lead to
deficiencies in the model.
