Building a cloud-based data sharing model for the Saudi national registry for implantable medical devices: Results of a readiness assessment

BACKGROUND

Implantable medical device registries are used as a medium to conduct post-marketing surveillance. Little information is available on the development and implementation of implantable biomedical device registries in general and specifically in Saudi Arabia and the Middle East.

OBJECTIVES

This study presents the experiences of building an implantable medical device registry in the Kingdom of Saudi Arabia. The work specifically addresses the early experiences of the Saudi Food and Drug Authority in the planning and development of a data sharing model for the implementation of a medical device registry at different hospital sites within the country.

METHODS

A two-year case study in which 60 health professionals from 5 hospitals in Saudi Arabia participated in a readiness assessment survey. The readiness assessment examined system-level capacity, hospital workflow and operations, clinical staff-level engagement, and technological assessment as they relate to the implementation of the Implantable Medical Device Registry (IMDR). Both subjective and objective data were collected as part of the readiness assessment survey at each hospital site. Data was collected from participants either individually or as part of a group at each hospital site. Using Microsoft Excel, Microsoft Word, flip charts, and back-and-forth discussion, the data was descriptively summarized and synthesized to provide an overview of hospital readiness for IMDR implementation.

RESULTS

Results show that there are large differences among Saudi hospitals in terms of their readiness for IMDR implementation due to a variety of factors relating to differences in hospital-wide organizational systems, clinical practice, technological infrastructure, and data sharing capabilities. Each of the hospitals surveyed in this study had differences in how clinical biomedical implantation policies and procedures were utilized. Manual entry into the cloud-based IMDR was recommended as the most optimal data sharing model that would mitigate the differences between hospital readiness for IMDR implementation.

CONCLUSION

Registries play a major role in monitoring the effectiveness of implantable biomedical devices. National standardized policies, enforced regulations, and information technology infrastructure are needed to achieve this goal. Furthermore, due to differences in hospital readiness, building a cloud-based registry system through manual data entry into the IMDR was found to be the most appropriate data sharing model that can be implemented at the national level.

In-home controls of pacemakers in debilitated elderly patients

AIM

We assessed the efficacy, reliability and cost of an in-home control service, devoted to debilitated patients with pacemakers, during long-term follow up.

METHODS

We admitted 802 patients (mean age 87.8 ± 6.9 years) with pacemakers into our program, which were monitored periodically during in-home visits by nurses. During these controls, patients underwent a standard electrocardiogram with and without magnet, during which stimulation intervals were measured. In-home pacemaker assessments were performed by a portable programmer only for patients with Biotronik pacemakers. Electrocardiograms and technical data were evaluated at hospital, and a report was sent by mail to the patient. Moreover, we compared the costs for the hospital, patients and society between in-home and ambulatory assessments.

RESULTS

During 80 months of follow up, 2418 controls were performed. The monthly average of patients who were followed at home was 283.9 ± 23.9. The mean number of controls per month was 30.2 ± 10 (range 4-51). One hundred and twenty-three pacemakers were replaced due to battery exhaustion, after a mean device longevity of 7.4 years (range 4.9-12.4 years). Four hundred and sixty-eight patients died (8.7% annual mortality). Fifteen patients (annual incidence 0.3%) were invited to in-hospital visits for reprogramming. The cumulative cost for in-home assessment were 20.5% lower than conventional in-hospital controls and 66.5% lower if patients are transported by ambulance.

CONCLUSION

Elderly debilitated patients can be monitored by effective and reliable pacemaker assessments at home, alleviating them and their families from the issues that are associated with their transfer from the home to the hospital and concurrently reducing overall costs.

[Progress in cardiac pacing]

This review discusses the utility and current status of remote monitoring in patients with cardiac devices in Spain, the different anticoagulation strategies used during device implantation, the surgical replacement and maintenance of pacemakers and defibrillators, and the present and future importance of impedance sensors in cardiac pacing and heart failure management. Finally, there is a summary of the most relevant scientific articles published in the last year.
