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.

Memory problems can be devastating as they limit independent functioning and disrupt social, family, and occupational roles. One form of remembering, prospective memory - remembering to attend to a task or event in the future—is particularly vulnerable to disruption. Fortunately memory is not a singular ability and patients can learn to compensate for memory difficulties by using preserved memory systems. Combining smartphone technology with appropriate training techniques has been shown to be effective in supporting prospective memory function even in individuals with amnesia. We have evidence that such technology may be used in a similar fashion to promote memory in mild cognitive impairment with the aim of delaying or preventing dementia onset. Even in dementia, memory training or support in forming new habits and routines which tap into preserved memory systems can be effectively used to help patients learn new names, reduce repetitive questions and remain oriented to the present. The best prevention is early intervention. Older adults presenting with memory complaints, no matter how mild, should be directed to maintain, reestablish, or institute habits of organization and written reminders, both to support current memory functioning and to preserve functional independence into the future should their concerns turn out to be the early manifestations of a neurodegenerative condition.

Infectious Disease Applications for Handheld Computers

Infectious Disease Applications for Handheld Computers


Philippe L. Bedard, MD, and Feisal A. Adatia, MD, MSc, First Year Ophthalmology Resident; University of Toronto, Toronto, ON.

Many health care professionals use handheld computers to access medical reference information and drug databases at the point of care.1 There are many specific infectious disease software applications for handheld computers, which combine information regarding specific microbial pathogens and sites of infections with antimicrobial databases and treatment guidelines. Infectious disease software may minimize medication prescription errors and promote more rational use of antimicrobials. This article briefly reviews the salient features of five popular infectious disease applications.

ePocrates ID
ePocrates ID is available with ePocrates Rx Pro, the purchase-based suite which includes the popular handheld drug database, ePocrates Rx. Users can search by location, bug or drug. ePocrates ID provides a numbered list of recommended antimicrobial regimens for both empiric and specific pathogen-based therapy. For each antimicrobial, users can tap on a hyperlink to be connected with ePocrates Rx for more detailed drug monographs. ePocrates ID offers the simplest and most intuitive interface of any available infectious disease handheld application. Busy clinicians can quickly find treatment recommendations and a wide range of well-organized antimicrobial information at the point of care. However, users should be aware that the manufacturer of ePocrates has the ability to track how information is accessed on ePocrates ID.2 Another drawback is that ePocrates cannot be run from an expansion memory card. ePocrates Rx Pro is expensive and users must renew their subscription annually. Unlike the core drug database in ePocrates Rx, ePocrates ID is not automatically updated with each hotsync operation, although users can download quarterly updates.

The Sanford 2003 Guide to Antimicrobial Therapy
The Sanford Guide is the handheld version of the popular paper-based infectious disease handbook. The opening screen of the handheld version is split into a "rapid reference" section of 17 commonly used tables and a searchable alphabetical index. The Sanford Guide provides the most detailed coverage of antimicrobial spectra, adverse medication effects and drug interactions and the most extensive literature references. However, unlike other applications, the information in the Sanford Guide is not organized by individual drug monographs, making it difficult to find information about a particular antimicrobial or clinical infection quickly. The search feature in the Sanford Guide is also cumbersome, as scroll bars must be used extensively to find information.

Johns Hopkins Division of Infectious Diseases Antibiotic Guide
Information in this guide may be searched through three side tabs entitled diagnosis, pathogen or antibiotic. Of the reviewed programs, this is the only one which is free and that automatically updates when a handheld syncs with a desktop computer. While being quite comprehensive and having undergone vigorous review for accuracy, this program does not provide any pediatric dosing. As well, drug monographs cannot be accessed through diagnosis or pathogen tabs, adding time required to search for drug details.

The 5-Minute Infectious Diseases Consult
This program is one of the extensive catalogues of medical reference books available from Skyscape. For users of other Skyscape references, the link feature allowing cross-referencing of databases is an attractive benefit. There are four indices that can be searched: Main Index, Microorganisms, Medication Index and Table of Contents. The Main Index is organized into basics, clinical manifestations, diagnosis, treatment, follow-up and selected readings. Perhaps the best feature of this program is its speed and ease of navigation. It is the most expensive of the reviewed databases and provides less drug monograph information than the other alternatives.

Infectious Diseases and Antimicrobials Notes
This program is formatted to run in iSilo, an e-book reader. It has the following sections: antimicrobial spectra index, prophylactic therapy, normal flora, organisms and treatment, infectious disease and treatment and antimicrobial treatment. This program has several attractive features. Its prophylactic therapy section provides details on prevention of infection with chemotherapy and provides surgical antibiotic prophylaxis notes. Its inclusion of a normal flora section is also quite educational. However, it requires extensive scrolling and lacks sidebar tabs seen in other applications. Furthermore, it does not disclose author information or provide references for its citations.

There is a variety of alternatives for users in search of an infectious disease reference for their handheld computers. ePocrates ID and Johns Hopkins Division of Infectious Diseases Antibiotic Guide provide the most concise and easily navigable treatment guidelines for particular clinical scenarios. The Sanford 2003 Guide to Antimicrobial Therapy may be most appropriate for specialists well acquainted with the paper-based version of the guide. The 5-Minute Infectious Diseases Consult offers the most extensive diagnostic information and can be linked with other Skyscape applications. Finally, the Infectious Diseases and Antimicrobials Notes may appeal to those in search of information regarding microbial flora and antimicrobial prophylaxis.

Internet Access: The Always On, Everywhere Phenomenon

Internet Access: The Always On, Everywhere Phenomenon



Feisal A. Adatia, MD, MSc, First Year Ophthalmology Resident, University of Toronto, Toronto, ON.

The Internet has become the world's greatest information resource. Physicians have come to depend on sites such as MD Consult ( and PubMed ( for their clinical queries, and family physicians have found Family Practice Notebook ( to be a valuable resource. As well, journals such as the Canadian Medical Association Journal ( and Geriatrics & Aging ( are available online to allow physicians to keep up with new developments in medicine.

With the SARS outbreak, the international community has used the Internet to share knowledge and information. The World Health Organization has responded to the threat of SARS by using its website to publish daily updates about the number of worldwide cases, thus allowing analysts to monitor the progress of this outbreak. In the U.S., the Centers for Disease Control and Prevention has posted dozens of fact sheets, travel advisories and a breakdown of domestic cases by state on its site.

Moreover, the Internet has become a trusted way to communicate, with e-mail having supplanted the use of the telephone in many regards. Given these changes, there is a great deal of excitement over new technologies that allow physicians to have the power of the Internet in a wireless device. Wireless systems also provide ways to share Internet connections and information between computers.

Bluetooth™ Wireless Technology
Bluetooth and Wireless Fidelity, or Wi-Fi, technologies are reshaping the way the Internet can be accessed. Bluetooth provides a means for devices to communicate with one another. This short-range technology allows for a wireless voice and data link between a broad range of devices, including desktops, notebooks, handheld computers, printers, mobile phones and digital cameras. Bluetooth creates a Wireless Personal Area Network (WPAN) consisting of all the Bluetooth-enabled electronic devices immediately surrounding a user, allowing these devices to communicate with one another. With this technology, desktop computers can send files to a printer, handhelds can synchronize with a notebook computer, one can surf the web via a mobile phone, and a wireless headset can be used to talk on a cell phone while driving. Physicians can use a Bluetooth-enabled notebook or handheld computer, such as the Palm Tungsten T, Sony TG50, iPAQ h5455 or Toshiba e740, to connect to the Internet via a Bluetooth-enabled cell phone, from companies such as Nokia, Motorola, Samsung and Sony Ericsson. However, to communicate, these devices need to be in close proximity, usually less than 10 metres.

Wireless Fidelity Technology
Wi-Fi technology allows one to develop a network, linking enabled devices through radio waves transmitted from a base station or access point. With this technology files can be shared between computers, and a single Internet connection can be shared by many computers. A larger range of approximately 100 metres allows this technology to become more feasible for broad access in public places.

It seems likely that many of us will adopt this technology, with mainstream pushes from suppliers such as Intel whose Pentium M chip, branded Centrino, includes Intel's Pro Wireless 2100 802.11b (Wi-Fi) module, expected to be included in 125 models of notebook computers by the end of this year. Palm's Tungsten C and certain HP iPAQ and Toshiba handhelds are currently Wi-Fi enabled. Intel is also teaming with Hilton Hotels and Resorts, Borders Group and McDonald's restaurants to offer wireless access to customers in certain areas. Mainstream Wi-Fi access is even available at Starbucks locations in the U.S., with 2,000 cafes expected to be wired for Wi-Fi by this year's end. AT&T and IBM have formed a company called Cometa Networks Inc. and plan to blanket the 50 largest U.S. metropolitan areas with public wireless access points, or "hot spots". Toshiba and Accenture also plan to have 10,000 hot spots across North America by the end of the year. In Canada, Toshiba has announced plans for a nationwide pay-per-use network of hot spots in more than 1,000 locations, including coffee chains, hotels and travel terminals. Bell Canada, Toronto-based Rogers Cable Inc. and Calgary's Shaw Cable Inc. also are expected to provide Wi-Fi access points, with Bell Canada having recently run a pilot project offering free wireless access at 19 public places in Montreal, Toronto, Kingston and Calgary.

In the health care setting, U.S. hospitals are using this technology to help provide working environments that will attract nursing staff. Internet Protocol (IP) wireless headset phones can use a Wi-Fi network to make and receive telephone calls. This allows nurses to answer doctors' pages on the spot, rather than having to hustle to a nursing station telephone. They can also use laptops or phones to update medical charts at bedsides. In fact, even north of Toronto at the Markham-Stouffville hospital, nurses use Wi-Fi-enabled laptops to feed information into the hospital's electronic documentation system from a patient's bedside. Although the employment of this technology is just beginning in the hospital environment, it is likely to become increasingly important in health care.

Technologies such as Wi-Fi are going mainstream and, perhaps more intriguingly, may revolutionize the accessibility of hospital staff and data access in our hospitals. In the future, wireless networks and everywhere access to the Internet may be a standard in clinical practice and in our homes.

A Guide to Choosing the Perfect Handheld Computer for Your Practice

A Guide to Choosing the Perfect Handheld Computer for Your Practice



Philippe L. Bedard, B.Arts, Sc, Fourth Year Medical Student.

Increasingly, physicians are turning to handheld computers for a variety of applications in their medical practices. For physicians interested in purchasing their first handheld computer or upgrading their existing model, this brief article introduces some important considerations.

Operating System
Although there are many different manufacturers of handheld computers, most handheld devices run on two operating systems (OS): Palm OS or Microsoft Pocket PC (formerly Windows CE). To determine which OS is most suitable, you should take into account which platform your colleagues are using to facilitate information exchange. The Palm OS is the current industry leader. Recently, Pocket PC has made significant market inroads with the release of more inexpensive models. In the medical arena, there are far more medical software titles designed for the Palm OS; however, many new medical programs are compatible with the Pocket PC as well.

The Pocket PC interfaces with MS Word and Excel out of the box. Files created in Microsoft applications on a desktop computer can easily be transferred back and forth with a Pocket PC. Most Palm OS devices come bundled with Documents to Go, a software program that allows you to work with Word and Excel files without the loss of fonts. Both platforms synchronise with Outlook for the popular functions of scheduling, contacts and to-do-lists.

Processor Speed, Memory and Expansion Support
The speed of the processor determines how quickly a handheld is able to retrieve information. Only recently have Palm OS handhelds started to use the faster processors that power Pocket PC devices. The fastest Palm OS devices run OS version 5.0. A handheld computer's internal RAM memory is akin to the hard drive of a personal computer. Palm OS handhelds offer either 8 or 16MB of internal RAM memory. Generally, this amount of memory is sufficient to support all of the personal information management programs on Palm OS devices, including calendar, to-do-list and datebook, along with one or two more space-intensive medical reference tools, such as pharmacopoeias and electronic textbooks. Newer models of Pocket PCs feature 32 or 64 MB of internal RAM. It is difficult to compare processor speeds and memory across these two platforms because the Pocket PC platform is more resource-hungry.

Many newer handheld models allow users to increase the storage capacity through expansion memory cards. Expandable Palm OS devices offer expansion slots that allow users to add an additional 8-256MB of expansion memory to their devices. However, of the current Palm OS devices, only select high-end Sony CLIE devices have dual expansion slots. There are several Pocket PC models that offer dual expandability, such as the inexpensive Dell Axim and various Toshiba models. Both Palm OS and Pocket PC handhelds are compatible with many peripheral add-on devices through their expansion slots, including digital cameras and full-size keyboards.

Size and Weight
Generally, Palm OS handhelds tend to be thinner and lighter than Pocket PCs. Some of the new and more popular Palm OS devices, such as the Sony T series and the Palm's Tungsten T, are small and light enough to fit comfortably into a shirt pocket. However, some multimedia Palm OS devices which also house built-in digital cameras, are larger. The new HP iPac H1910 is the smallest of the Pocket PC family.

Palm handhelds feature either a monochrome or colour screen. However, not all monochrome screens are identical; some offer much sharper resolution that makes for easier reading of text. Similarly, like digital cameras, colour handhelds differ in the number of colours that are supported and the screen resolution. Currently, Palm OS handheld screens range from 160X160 pixels to 320x480 pixels. All Pocket PC devices feature a colour screen with resolution of 320x240 pixels. If you plan to use your handheld to read a lot of text or to view graphics, it may be worthwhile to invest in a higher-end resolution model.

Input Methods and Convergence Features
Handspring's Treo and the Sony CLIE TG50 and N series are Palm OS devices with built-in thumb-boards which are an alternative to stylus-driven data input. High-end Palm handhelds offer MP3 playback and voice recording features that are standard on all Pocket PCs. Phone-hybrids, Internet and e-mail functions and digital cameras also are available on some models of Palm OS and Pocket PC devices.

In summary, a clear understanding of your handheld needs should guide your decision-making. If all that you require is quick and simple calendaring, reminders and contact management, then an inexpensive Palm OS handheld should suffice. If you foresee your handheld as a medical information resource at the point of care, look to an expandable Palm OS device or a low-end Pocket PC. Finally, if you have greater multimedia demands, desire a colour screen, and would like to play MP3s, watch video clips or edit digital pictures, then consider Palm OS 5 devices or a new Pocket PC.
