Systems Development Life Cycle (SDLC)
The SDLC is a process used to develop an information system, including requirements, validation, training, and user ownership through investigation/planning, analysis, design, implementation, and maintenance.
The SDLC phases include:
Planning: Identifying the need for a new system, defining the scope, and conducting feasibility studies.
Analysis: Gathering and analyzing requirements, understanding business needs, and creating a logical model of the new system.
Design: Creating detailed technical specifications, including system architecture, data models, and user interfaces.
Implementation: Developing, testing, and deploying the system, including data migration and user training.
Maintenance: Ongoing support, updates, and improvements to ensure the system continues to meet business needs.
Needs Analysis and Gap Analysis:
Conducting a needs analysis involves identifying the main challenges in the sector and specifically those needs that can be sufficiently met by the implementation of sustainable, secure, and cost-efficient IT practices1.
A gap analysis assesses the differences in performance between an organization’s systems to determine whether business requirements are being met and, if not, what steps should be taken to ensure they are met successfully
Process Improvement
Process improvement involves identifying, analyzing, and improving existing business processes to optimize performance, meet best practice standards, or simply improve quality and the user experience for customers and end users1.
Common methodologies include DMAIC (Define, Measure, Analyze, Improve, Control) and PDCA (Plan, Do, Check, Act)
Workflow and Process Mapping
Workflow and process mapping serve as mechanisms to understand current processes and how work is performed to begin the change management process1.
These methods help identify broken processes and provide an opportunity to address them before a system automates them
Requirements Analysis
The requirements analysis documents what the system actually does and keeps the project aligned with the identified scope1.
It includes functional and non-functional requirements, reporting/analysis capabilities, regulatory requirements, data/database, security, system performance, disaster recovery, platform compatibility, interface and interoperability, physical plant consideration, client devices, and network
Cost-Benefit Analysis
A cost-benefit analysis (CBA) evaluates both the costs (e.g., hardware, software, installation, training, maintenance) and the benefits (e.g., cost savings, improved efficiency, better patient care) of implementing a new system1.
The CBA helps determine the net impact of the project and the payback period

Alternate Processes for Healthcare Systems
Industry Standardization:
The Healthcare Information Technology Standards Panel (HITSP) and the Office of the National Coordinator (ONC) have made significant progress in IT integration over the past decades. Future initiatives might include developing an integrated architecture that meets a cross-section of market needs. This platform would link with all major existing software and hardware configurations in the market, such as electronic health records (EHRs), data management systems (DMSs), and imaging programs.
Reducing Prescription Errors:
Prescription errors can be addressed locally while awaiting market integration standards. Many software applications are dedicated to prescription information and decision-support systems. Avoidance of adverse drug events (ADEs) is a major key performance indicator (KPI) that can be addressed by IT implementation in healthcare. Clinical decision-support systems (CDSS) provide updated information regarding recommendations for prescriptions to nurses, physicians, and other qualified healthcare workers. This system is typically integrated with the EHR and computerized practitioner order entry (CPOE) systems to perform proper scenario analysis with appropriate patient backup before a provider writes a prescription1.
Revenue Generation:
Financial processes can be simulated in IT process integration due to their general nature and resemblance to other industries’ financial processes. Revenue generation draws primarily from workflow optimization, which seeks to reduce query time and queue time, reduce waiting time through the implementation of fast patient data retrieval and diagnostic support, and reduce laboratory scheduling and patient briefing time by enhancing fast decision-relay procedures and online client information alternatives. Online support may be an easy way for patients to obtain their lab results electronically signed by their care providers without having to wait in queue
Potential Solutions for New or Improved Applications
Electronic Health Records (EHRs):
EHRs involve standardizing the way in which patients’ records are entered, stored, and retrieved, not just within an organization, but across different hospitals, caregivers, government-controlled organizations, and other interested parties. The biggest challenge regarding EHRs has been the establishment of an industry standard to allow for seamless retrieval and use of records for patients, even when patients are moved to units or facilities other than where they were initially treated1.
Computerized Practitioner Order Entry (CPOE):
CPOE may replace conventional order cataloging and fulfillment in a manner that enhances tracking, logistic synchronization, and cost-effectiveness. It can also reduce medication errors by providing decision support to practitioners regarding medication and procedures, including warning systems relating to high-risk medications and processes1.
Clinical Decision-Support Systems (CDSS):
CDSS provides informative guidelines to practitioners regarding medication and procedures, including warning systems relating to high-risk medications and processes. This system is typically integrated with the EHR and CPOE systems to perform proper scenario analysis with appropriate patient backup before a provider writes a prescription1.
Picture Archiving and Communication System (PACS):
PACS integrates inputs from multiple radiological and diagnostic tools to allow easy, consistent, and accurate treatment of different conditions. It also helps in reducing the need for physical storage of images and films1.
Automated Dispensing Machines (ADMs):
ADMs aid in drug dispensing, while electronic materials management (EMM) systems operate like the resource planning systems used in other sectors to manage information processing regarding pharmaceuticals, new drug development, and coding.
By implementing these alternate processes and potential solutions, healthcare organizations can improve patient safety, enhance operational efficiency, and achieve better financial performance. If you have any specific areas or systems you would like to explore further, please let me know
