5 Technological Innovations for Those With Dementia


Holly Clark, Freelance Health Writer

Dementia can be terrifying and devastating to both caregivers as well as the loved ones affected by this disease. People with this disease can now feel some relief due to technological advancement which is meant to improve the quality of their lives. This technology can enhance autonomy as well as independence, manage possible risks in homes and get rid of stress.
In this article, we are going to look at the 5 technological innovations for those with Dementia

1. Communication Aids
Interacting with others is necessary for the quality of life in memory care. Individuals with dementia can remember how an event has made them feel, even if they are unable to recall the faces and names. Technology has simplified the interaction process with loved ones. Adapted telephones are now programmed with contacts that are frequently dialed and usually have bigger buttons which simplify their usage. It's now possible to stay connected with loved ones who are distant apart via the video chat services.
"Changes in the brain caused by dementia begin years before diagnosis. And throughout this timeframe, there are no clear signs that that person has dementia." comments Jane Byrne, Project Coordinator at FirstCare.1

2. Electrical appliance use monitoring

This innovation is meant for caregivers who do not stay together with their loved ones. It controls the use of electrical apparatuses through plugging into a power strip or wall outlet as it will notify caregivers when their appliances have been switched on or off. These technologies do not make the diagnosis of dementia easy. This disease is yet overwhelming. The dementia is now more manageable; this is due to the innovation in new technologies.

3. Reminder messages
Reminders play an important role as the caregiver does as they help to keep the loved ones safe and also retain their relationships. The recording of these messages is done on a device in the residential area and then played out loud at the most suitable time. Caregivers can record a message that when played reminds an individual to take medication at the appropriate time. Some gadgets are designed to play messages based on individuals activity. Some devices are meant to remind individuals with dementia to lock the front door when leaving home. There are other reminder messages designed to help people with dementia on when to close the door when to go to bed and provide reassurance at times when the caregiver is not present.

4. Home care robots Technological advancement has led to the invention of homecare robots which will help reduce the caregiver duty. They are not designed to replace human caregivers, but instead, they are meant to do overall housework and remind individuals who are suffering from dementia on when to take medication or notify medical experts when assistance is required. With further inventions, home care robots may replace caregivers and handle their responsibility fully.

5. In-home cameras
In-home cameras are another technological innovation that is meant to enhance the safety of your loved ones from a distance.2 By either positioning, the camera focusing on medication or in the entrance room can increase your confidence as you are sure your loved one is taking the necessary medication and also active. These cameras can monitor movements and also enable one to communicate with his or her loved one. It will also notify you if no movements have been detected for a particular period.

5 Ways Technology Is Leading The Revolution In Patient Care

Rahul Varshneya is the co-founder and President of Arkenea and Benchpoint. Rahul has been featured as a business technology thought leader in numerous media channels such as Bloomberg TV, Forbes, HuffPost, Inc, among others.

Technology is proving itself to be a driving force behind innovations in the healthcare industry. Advances in medical technology are empowering both patients and healthcare providers to take data driven decisions for better health outcomes and improved care efficiency.

Healthcare currently accounts for 17.8 percent of annual GDP spending in the US, which is projected to rise to 19.9 percent by 2025.1 Adoption of technology is slated to play a major role in this growth in healthcare and prove immensely beneficial for everyone within the chain of care.

Here are the ways technology is leading the revolution in patient care:

1. Rise in Electronic Health Records
Data is the backbone of technological developments and widespread adoption of EHRs across hospitals has made the collection and analysis of healthcare data an easy task. 86.9 percent of all physicians make use of EHRs to store patient data.2

Storage, maintenance and analysis of this data is important for efficient monitoring of the patients. Advances in computing methods, big data analytics and use of artificial intelligence to sift through medical data at revolutionary pace and obtain meaningful results is all contributing towards better patient outcomes.

Adoption of EHRs comes with it's own set of challenges, data security being the biggest threat of all. According to research, healthcare industry is subjected to 340 percent more security incidents than any other industry and is 200 percent more likely to encounter data theft.3 Storage of medical data thus has to be done ensuring the security measures are in place and sensitive patient data is always protected.

2. Increased Adoption of Telehealth
Telehealth is revolutionizing patient care by making healthcare services more accessible to all. CMS recently proposed it's 2019 Medicare Physician fee Schedule and Quality Payment Program that would result in increased adoption of telehealth services.4 The proposed changes would result in advancing virtual care for patients by leveraging technology, laying down norms for physician reimbursement for telehealth services, thus reducing physician burden.

The widespread use of smartphones and advances in mobile networks and connectivity has enabled the physicians to have virtual consultations with the patients. It negates the need for the patient to travel down to the physician's office for a routine health consultation which is extremely important in case of chronically ill and debilitated patients.

It also makes patient management more efficient by streamlining patient appointments and reducing wait times. Remote patient monitoring results in better health outcomes while reducing healthcare costs. Use of telemedicine to tackle ER triage recorded a 25 percent reduction in staffing costs in the hospital, while increasing the admission rate by 20 percent.5

The telehealth market is already growing fast and is projected to reach 52.89 billion by the end of 2025.6 It has already transformed patient care and further technological advancements like advent of 5G technology will give it a further boost in the days to come.

3. Wearable Tech and Internet of Medical Things
One of the most important technological revolutions in recent times has been the advent of wearable devices. The smartwatches sale is projected to reach 86 million units by 2021 which will be only 16 percent of all wearable devices.7

Equipped with state of the art sensors, these fitness and medical devices track the individual health stats empowering it's wearer to take conscious, data driven health decisions.

The healthcare data collected by these devices is also utilized by the healthcare providers in order to curate customized care plans on the basis of individual needs. The in-built sensors detect any abnormality in the readings resulting in an early diagnosis of the underlying conditions.

Use of Artificial intelligence tools to compute the data collected by these devices can help predict disease trends across populations and bring about a data driven revolution in the field of medical research.

4. Patient and Workflow Management
Leveraging technological tools like Artificial Intelligence8 to automate the routine tasks in patient management can ensure that the doctors and nurses9 can prioritize on the more important tasks on their hands. Use of technology to manage things like patient registration, filling in the notes in patient's medical records, processing discharge and payments not only results in saving time and resources within the hospital, but it also makes the workflow within the hospital more organized and optimized.

Use of self serving kiosks for patient registry, voice to text input of patient data into medical records, use of chatbots for routine conversations with patients to ensure patient compliance are some of the ways in which technology is transforming patient management.

Automation of the routine non-emergency tasks would result in better focus on the emergent cases and more time spent by both doctors and nurses at the patient's bedside, resulting in greater patient satisfaction and improved patient outcomes. An optimized hospital workflow also results in optimal usage of resources thus saving operational costs.

5. Mobility in Healthcare

Mobility in Healthcare10 is going to undergo a revolutionary growth of 28.3 percent by 2022 allowing the focus to shift from hospital based care to a more patient centric approach.11

Development of robust mobile apps12 empowers the physicians to provide the best possible treatments, resulting in more positive patient outcomes and overall decrease in treatment costs. Rise of mobility has made it possible for the patient data from the wearable devices to be integrated into the EHRs resulting in a more holistic care plans to be designed for specific patients.

Mobility in healthcare also results in better workflow optimization within the hospital by tracking the real time location of the healthcare providers resulting in better access and communication.

Summing up
The field of healthcare has historically been one of the last segments to adapt to rapidly changing technology. The scenario is now transforming with the gradual inflow of advancements which have resulted in a renovation of the healthcare sector. While the applications are plenty and the transformation has just begun, one thing is for sure, incorporation of technology in healthcare is leading us towards a brighter future.

Evidence in the Palm of Your Hand: Using PDAs to Implement Clinical Practice Guidelines in Primary Care

Evidence in the Palm of Your Hand: Using PDAs to Implement Clinical Practice Guidelines in Primary Care


D'Arcy Little, MD, CCFP, Lecturer and Academic Fellow, Department of Family and Community Medicine, University of Toronto, ON.

"The best predictor of successful guideline implementation is the provision of guideline-based recommendations that are patient specific at the time and place of the patient consultation."1

The need for relevant and timely information at the point of patient care is paramount in primary medicine. The routine care of patients necessitates having, at the clinician's fingertips, up to date information about the diagnosis, prognosis and treatment of many illnesses.2 In fact, it is estimated that two important clinical questions are generated for every three patients seen in the office.2,3 However, it is increasingly difficult to keep up to date; physicians who want to keep up with relevant journals in their field would need to review 19 articles per day, 365 days per year.2,4

The development and dissemination of clinical practice guidelines (CPGs) is one attempt to consolidate and make available information that clinicians can easily use in clinical decision-making.5 However, many guidelines may be in a format that is not user-friendly for busy daily practice.6,7 The purpose of this article is to review the role of Personal Digital Assistants (PDAs) in the implementation of CPGs, including a review of the available evidence for this practice.

PDAs and Evidence-Based Medicine
It is important to note that the use of PDAs does not replace any of the steps involved in practising evidence-based medicine (EBM), but it may make some of them easier. Table 1 reviews the steps devised by Straus and Sackett that are necessary to practice EBM.2 PDAs have the potential to make the best evidence available at the point of care in a fast and easily digestible format,6 thus facilitating steps 2, 3 and 4.

Barriers to Guideline Implementation
The four-stage Pathman Model has been used to delineate the barriers that exist in guideline implementation. The steps include awareness, agreement, adoption and adherence.8 For a guideline to be implemented, a physician must become aware of the guideline, then intellectually agree with it, decide to adopt it in the care he provides, and finally regularly adhere to it at appropriate times.9 Some physicians consider clinical guidelines to be akin to "cookbook medicine". As such, they balk at the idea of using decision support tools in their practice.10 PDAs may not leverage these physicians at the agreement stage; however, PDAs may have a role in the other three steps of guideline implementation.

Evidence for the Use of PDAs for Guideline Implementation
Approximately 30% of physicians now use PDAs, a number expected to increase to 50% by 2005.11 A recent systematic review of PDA use in medicine has acknowledged that despite the explosion in their use, there is a paucity of evidence-based information.12 The available evidence is discussed here.

Sackett and Straus have shown that the availability of a mobile "evidence cart"--consisting of EBM and medical reference material stored in laptops or paper inventories--in a busy inpatient medical service increased the extent to which evidence was sought and used in patient care decisions.13,14 However, the cart was found to be too bulky to take on bedside rounds. PDAs have the potential to serve as an optimally-mobile "evidence cart". Commonly used medical applications for PDAs include textbooks, rules and calculators, pharmacopoeias as well as scheduling and patient tracking programs. Recently, sites which have CPGs in PDA format also have become available ("A Brief Guide to Some Free Evidence-based Medicine Resources for the PDA" is available online at

Because many of the studies describing the use of PDAs in implementing guidelines are continuing, often only descriptive reports are available. There is, however, one randomized trail suggesting that the use of PDAs can enhance guideline implementation. A before-after trial with randomly selected pediatricians assessed the effect of the use of PDAs with respect to asthma guideline adherence.15

In the control and intervention phases, physicians collected data from 10 patient encounters for acute asthma. During the intervention phase, PDAs provided structured documentation and offered recommendations based on the asthma guidelines of the American Academy of Pediatrics. Patients were followed up by telephone in 7-14 days to assess outcomes. Nine physicians enrolled 91 patients in the control phase and 74 patients in the intervention phase.

The use of PDAs was found to increase physician guideline adherence. Specifically, there was more measurement of peak expiratory flows and oxygen saturation, as well as increased administration of nebulized B-2 agonists and inhaled corticosteroids.

Patients in the intervention group tended to have a greater immediate clinical improvement, but this was not the case with intermediate term outcomes, which were similar between the groups. There were no differences in patient outcomes with respect to emergency room visits, hospitalizations or missed days of school at seven days post-visit. This may have been a power issue, as the study was relatively small. In addition, the visits in the intervention group were found to be slightly longer and more costly.15

A prospective controlled pilot trial randomized family physicians to receive PDA software to help manage suspected angina or conventional care. The software consisted of an algorithm that converts the patient's demographics, risk factors and findings into the probability of having coronary artery disease, and hence directs the clinician to the appropriate investigations and treatment. The software was found to increase overall use of cardiac stress testing, with a trend toward more appropriate use of stress testing. The conclusion that PDA software may lead to improvement in the primary care management of suspected angina will be further examined in a larger trial.16,17

Handheld devices are gaining wide acceptance among physicians. Sites are available that literally put evidence-based medicine in the hands of physicians at the point of care. PDAs are a viable way to increase physician awareness of guidelines by allowing guideline programs to be easily downloaded and searched, and to increase physician adoption of and adherence to guidelines because the required information and reminders are close at hand and usable during patient encounters.

However, the actual guidelines that are chosen for implementation must be carefully selected. For example, several of the guideline steps in the Asthma study above, such as the administration of oxygen during an asthma exacerbation, are consensus statements without qualification of the evidence or the strength of the recommendations. All guidelines, particularly those that are to be implemented on PDAs, should be rigorously assessed with respect to their scope and purpose, stakeholder involvement, rigour of development, clarity and presentation, applicability and editorial independence.18,19 Finally, the current lack of randomized controlled evidence for guideline implementation via the PDA will likely be remedied with time, as more such studies are completed and reported.
