A Definitive Guide To Cloud Computing In Healthcare
Multifold increase in the amount of healthcare data generated and widespread digitization of healthcare records has resulted in the movement of healthcare data from the conventional paper based systems onto digital platforms. Healthcare industry is rapidly realizing the potential of cloud computing and the benefits it offers.
According to a report, the global healthcare cloud computing market is expected to register a CAGR of 18% during the forecast period, 2018 to 2023 and is projected to reach $14.8 billion by 2022. According to healthcare technology trends, this growth in adoption of cloud technology is fuelled by increasing demand for remote accessibility to data, increased patient awareness, easier access to advancements in technology and increasing adoption of IT in healthcare.
While it’s clearly established that cloud computing is being increasingly adopted in healthcare industry, let’s take a look at how it will benefit the patients as well as the healthcare providers.
Key Benefits of Cloud Computing in Healthcare
1. Financial Advantages
Lesser capital investments: Shifting to cloud platforms is instrumental for avoiding heavy capital infrastructure and allows for more flexibility in spending. Setting up a cloud network does not require upfront capital investment into infrastructure as the IT systems can be acquired on the basis of need when required.
Cost flexibility: Cloud computing includes the cost of staff resources required to deploy and maintain IT resources, thus negating the recruitment and training of skilled IT personnel. Additionally the cloud infrastructure is set up maintained externally. Healthcare organizations do not have to acquire the necessary hardware, software and personnel. They only need to pay for the services actually availed by them making it relatively cheaper.
2. Operational Advantages
Remote accessibility: The biggest advantage of storing data on cloud is the ability to access and retrieve the relevant data from any location. Healthcare experts can review the data even from remote locations using secure access logging making healthcare more accessible to the population.
Scalability: The cloud services have the inherent ability to adjust to fluctuations in demand. In case of a rapid increase in demand, the servers offer scalability and can accommodate rapid rise in demand that may arise due to situations like a disaster or an epidemic.
Enhanced security: Cloud hosting is a great way of protecting sensitive medical data. Sophisticated security measures such as data encryption, filtering of access and secure access login can easily be implemented by healthcare developers and service providers into the data cloud making it more secure than the conventional data storage techniques.
3. Functional Advantages
Interoperability: The cloud systems can easily be connected to other systems and applications via the internet, making interoperability and integration easy. It also makes sharing of vital information possible in a secure manner while complying with the data security regulations.
Analytics: Application of analytics on the vast amount of data stored in the cloud is vital for retrieval of clinically relevant health information. This is important for creating patient specific treatment plans for better health outcomes as well as for gaining population health trends and insights. Cloud and big data services can be employed for tracking of infectious diseases, mapping them geospatially and informing the population about the existing risks.
Important Considerations for Selecting the Cloud Service Provider
Before leveraging cloud technology in the field of healthcare, it has to be ensured that the service provider is able to overcome the set of challenges that could affect widespread adoption of cloud computing in healthcare.
- Privacy and Security: Healthcare data is extremely sensitive and is 200 percent more likely to encounter data theft. This makes ensuring privacy and security of data a really big challenge. Healthcare entities need to establish strong agreement with the cloud service providers with special provisions for privacy and security of data. The risks and liabilities in regards to patient health information must be fully understood and healthcare providers should always stay informed about the manner in which PHI is stored and managed. Use of third party authentication is highly recommended for accessing the medical data stored on cloud.
- Regulations and Compliance: Patient health information collection and storage is subject to a number of governmental regulations like HIPAA and GDPR. Compliance to these regulations is mandatory when storing data on the cloud platform. While selecting the cloud service provider, it is necessary to ensure that the data regulations by the government agencies are adhered to. The cloud service providers may have certifications from regulatory authorities but the responsibility of ensuring compliance remains with the healthcare providers. Signing of BAA (Business Associate Agreement) and SLA (Service Level Agreement) should be done with the cloud service providers before finalizing the cloud platform.
- Service Reliability and Management: The cloud service providers need to able to upgrade the system as and when the need arises. Scaling is another critical factor while selecting the service provider. The platform chosen should be able to process unexpectedly huge loads of data at any given time. The key performance indicators of performance and reliability need to be constantly monitored.
- Integration and Interoperability: The cloud platform should be an end to end system that fully integrates all patient data which also includes data from the connected medical devices. Standardization of data and integration of the cloud systems across the existing health IT systems is necessary to ensure maximum interoperability.
Future Trends in Cloud Computing
- Hybrid Clouds: Public clouds raise security concerns and private clouds are too expensive. Hybrid clouds offer the best of both worlds by giving a secure cloud environment at an affordable rate with a number of touch points between the two environments. The hybrid platform equips the users with the freedom to decide which apps and resources need to be kept exclusively in the data centre and which to place within the cloud.
- Big Data analytics: Use of analytics techniques on the data stored on the cloud using big data analytics and machine learning algorithms can considerably speed up the research process. Access to relevant medical information in a timely manner can help advance precision medicine and help predict population health trends.
- 5G technology: Launch of 5G technology by 2020 would result in access to greater bandwidths resulting in faster data transfer. It would greatly impact sharing of medical data in the form of images and/or videos at a faster rate.
