Inefficient Patient Data Sharing:

The use of outdated, paper-based record-keeping systems in many healthcare facilities still results in a laborious and inefficient process. Patient data must be manually recorded, stored, and retrieved by medical personnel, which causes needless treatment delays. Healthcare workers’ workloads are increased by this inefficiency, which takes them away from providing patient care. Paper documents are also more likely to be lost, damaged, or duplicated, which makes data administration much more difficult. Higher administrative expenses and longer patient wait times are the results of inefficient digital sharing.

Using digital solutions to update these antiquated processes can greatly increase productivity, decrease paperwork, and foster better teamwork among medical practitioners. Healthcare organizations may increase operational effectiveness and give patients faster, more accurate care by switching to digital data-sharing techniques.

Lack of Transparency in Medical Records Access:

Patients lacked control over their medical records and sometimes didn’t know who could access them or why. Concerns about data misuse, unauthorized sharing, and privacy issues were brought up by this lack of openness. Healthcare practitioners relied on antiquated, manual record-keeping methods that were based on paper. These inefficiencies caused the healthcare industry’s operational expenses to rise, administrative workloads to increase, and medical treatments to be delayed.

Rising Healthcare Fraud and Financial Losses

Healthcare fraud is a rising issue that costs the sector billions of dollars every year as a result of identity theft, inconsistent billing, and false claims. False insurance claims, overcharging for services, and prescribing needless therapies in an effort to boost profits are examples of fraudulent activity. The National Health Care Anti-Fraud Association reported in 2024 that the annual cost of healthcare fraud to the American healthcare system exceeds $68 billion.

These practices put a burden on insurance companies, increase patient healthcare expenses, and deplete resources for necessary medical care. When needless procedures are performed for financial gain, fraud jeopardizes patient safety in addition to financial considerations. These risks can be reduced by tightening rules and bolstering fraud detection systems.
