Present day decision making in healthcare has become a data-intensive process leading to the rise of healthcareanalytics. These analytics involve the integration and analysis of data collected from multiple heterogenoussources including biomedical data (electronic health records), experimental (R&D) data, patient lifestyle andbehavior data (store records, social media, wearable electronic devices etc) and financial data. Healthcareanalytics is further being transformed by the application of current - omics technologies (genomics,epigenomics, transcriptomics, proteomics, metabolomics, pharmacogenomics etc), shifting healthcare to asystem that is “predictive, preventive, participatory, and personalized”, referred to as the P4 medicineparadigm. The omics revolution is generating a huge amount of data that needs to be collected, stored,transformed, analyzed and ultimately delivered in a format that is understandable to the clinicians. Properlyapplied, healthcare analytics provide actionable insights that can lead to improvement in healthcaremanagement and delivery, clinical outcomes, health policies and allocation of health resources to communitiesin need.
Medical institutions worldwide are facing many challenges. There is a shortage of trained human resource,patients are more demanding and regulators are becoming more stringent. The healthcare systems are underpressure to provide better and safer healthcare that is also more cost-effective. This is leading to thedevelopment of a whole new healthcare analytics industry to capture, store and analyze big data for healthcareproviders, health system leaders, and those in government health and human services to improve healthcaredelivery and outcomes. A report by McKinsey Global Institute published in 2011 estimated that if US healthcarewere to use big data creatively and effectively, the sector could create more than $300 billion in value everyyear.1
While innovative new technologies and platforms are making it possible to capture vast amounts ofinformation of individual patient over a large timescale, a large amount of data remains underutilized andwasted. It is estimated that healthcare providers discard around 90% of the data that they produce.1 One of thegreatest challenges in healthcare analytics is harvesting the data from multiple complex and heterogenoussources spread across different healthcare systems, health insurers, scientists, government bodies etc. andtransforming it to generate meaningful information. Moreover, the personal and financial data and medicalrecords of patients required to contribute to effective analytical platforms may be confidential and private andtherefore inaccessible. Hospitals are also reluctant to share their financial and clinical audits. There is the issuealso of ownership of the data and in many countries patient data is legally possessed by the patient. Even so thehealthcare industry, slow to transition towards data mining and IT solutions, has now begun to adapt to thedigital data age. Algorithms for collecting, compressing, anonymizing and sharing medical data are beingdeveloped by different groups in addition to various platforms specific to healthcare analytics.
The implementation of healthcare analytics, particularly in developing countries like Pakistan where mosthealthcare facilities lack even the most basic form of EHRs is a formidable challenge. Pakistan has a robust ITcommunity with a special interest and investment by the government sector in IT and Artificial Intelligenceplatforms. Pakistan government last year announced seed money of Rs 1.1 billion, to carry out a three-yearproject on AI, through the Higher Education Commission to be conducted by six universities. One of theseprojects, related to medical imaging and diagnostics, is a step in the right direction. However, we still have a long way to go if we are to reap the benefits of healthcare analytics in Pakistan. There is a need for the involvement and commitment of all stakeholders including healthcare facilities, academicians, researchers and industry etc to contribute to this endeavor. There is no shortage of qualified human resource in the country. All that is required is the will of the health sector to invest in this golden opportunity for healthcare analytics to play a role in improving the delivery of cost-effective care, save lives and define health policies in Pakistan.
