The Non Radiological Imaging Phycisians Health And Social Care Essay

In 2011, the Southern Philippines Medical Center acquired a Picture archiving and communication system (PACS) in the hope to help facilitate fast, speedy and reliable, cost-effective radiological imaging portals. On its one year of operations, a number of issues were raised like needs of additional viewing stations, medical grade and non-medical grades alike, offering of seminars and workshops to help end-user learn how to use the viewing stations for better visualization of images, and problems on retrieving images and their storage.

These issues were raised time and again in the hospital’s ER, OPD, MEDMANCOM, EXECOM and Training Office meetings. But a detailed evaluation and assessment on the aforementioned issues were not validated.

This study is a timely assessment on SPMC-PACS one year operations as perceived by our client.

Review of Related Literature

Picture archiving and communication system (PACS) is a medical imaging technology which provides economical storage of, and convenient access to, images from multiple modalities. Electronic images and reports are transmitted digitally via PACS; this eliminates the need to manually file, retrieve, or transport film jackets.(1)

Electronic health information systems, such as picture archiving communication systems (PACS), are commonly believed to reduce the need for duplicate testing.(2) However, empirical data to support this belief in Southern Philippines Medical Center are not available.

PACS allows for a near filmless process, with all of the flexibility of digital systems. It also removes the costs associated with hard film processing and releases valuable space previously used for film storage. Most importantly, PACS is helping to transform patients' experience of the care they receive across the NHS. It does this by enabling a speedier diagnosis and by removing the risk of images being lost or misplaced.(3)

Picture Archive and Communication Systems (PACS) are comprehensive management systems for diagnostic imaging studies that are increasingly used in hospitals and health care systems. It is essential for PACS to be an integrated part of the total hospital electronic information system in order to be maximally effective. The main objective of any new information system in health care is to improve the effectiveness and efficiency of health care. Although the initial implementation of PACS is costly, the ability for care providers to have faster access to diagnostic imaging information allows care to be delivered more expediently, which improves the overall quality of care patients receive. (4)

Picture archiving and communication systems (PACS) present an opportunity to radically change film-based radiology services both inside and outside the hospital setting. In the past, the usual medium for capturing, storing, retrieving, and viewing radiology images was hard copy film.(5)

Conventional film and paper-based information systems are currently being replaced by information technology in many hospitals and imaging centers. Radiology information systems (RIS) typically support administrative functions, frequently also reporting of results, while picture archiving and communication systems (PACS) typically acquire, store, transmit, display, and process digital images.(6)

One of the main benefits that PACS provides is the ability to provide a timely delivered and efficient access to images, interpretations and related data throughout the organisation. This helps to ease consultations between physicians who can now simultaneously access the same images over networks, leading to a better diagnosis process.(7)

It is also beneficial to physicians in emergency situations, as they need not wait for long periods in order to view a patient’s radiological images as these are instantly available on the network when ready.(7)

Another feature of PACS is the ability to digitally enhance the images, providing more detailed and sharper images. This improves diagnostic capabilities at radiological examinations.(7)

The high costs of PACS has led to vendors offering mini-PACS, which is a cheap alternative for organisations that cannot afford the cost of a full PACS system or those seeking to implement some form of a digital image management system but would rather start off with something small.(7)

Advantages of PACS

Rapid access to critical information to decrease exam-to-diagnosis time. This is especially useful in emergency and operating rooms.(7)

Elimination of film, handling and storage costs.(7)

Images can be easily shared between reading radiologists, other physicians and medical records.(7)

Images can be archived at secure locations using database servers manages the transfer, retrieval and storage of images and relevant information; the archive provides permanent image storage.(7)

Radiologists can access soft-copy images instantly after acquisition to expedite diagnosis and reporting at the almost any available workstation.(7)

Web servers can be used to most cost-effectively share images with other departments, even referring physicians across town. They can access the images using the Internet or the local intranet.(7)

No similar studies done in this institution upon the advent of PACS system in November 2011 until this day. Published studies for national and regional levels are likewise not demonstrated on literature review. Thus, this serves as a pilot study.

Research Problem

The increasing number of patients in the emergency room (ER), in-patient and out-patient, department as well as in the operating room entails faster, efficient, safer, and larger storage space thus the need to avail of the PACS coupled with problems with regard to lost films, film packet, storage problems, immediate access to and availability of images and immediate access to radiology reports.

Significance of the Study

A picture archiving and communication system (PACS) is a computerised means of replacing the roles of conventional radiological film: images are acquired, stored, transmitted, and displayed digitally. When such a system is installed throughout the hospital, a filmless clinical environment results. The main purpose of building a complete filmless and paperless system for a hospital is to improve the quality of medical and patient service. At the same time, its cost-effectiveness is also important and we need to give due consideration in the benefit on hospital management.

This study aims assess how useful the PACS in service delivery for radiological imaging using x-ray, CT scan and MRI requests from non-radiological imaging physicians.

DEFINITION OF TERMS

Digital imaging and communications (DICOM) systems: A standard for the facilitation of electronic medical imaging, consisting of a standardized image format and a standardized communications protocol.(4)

Electronic health record (EHR): An electronic system that is used to capture, retrieve, store, transmit, manipulate, and link any information that relates to the past, present, and future health or conditions of any person for the primary purpose of providing health care or health-related services. EHRs are usually based on the Health Level Seven (HL7) standard.(4)
