I first searched in MEDLINE with the MeSH term “computers, handheld”. The National Library of Medicine (NLM) summarises the following entry terms under this MeSH: “computer, handheld”, “handheld computer”, “handheld computers”, “computers, palmtop”, “computer, palmtop”, “palmtop computer”, “palmtop computers”, “computers, palm-top”, “computer, palm-top”, “computers, palm top”, “palm-top computer”, “palm-top computers”, “personal digital assistant”, “digital assistant, personal”, “PDA

Platforms and operating systems
In the past, hand-held computing was restricted to sophisticated programmable calculators with or without a data storage option. By comparison, most PDAs currently run on the mobile operating systems of either Palm OS (PalmSource Inc, Sunnyvale, CA, USA) or Microsoft Windows (Microsoft Corp, Redmond, WA, USA) that, in addition to their intrinsic functionality, allow customisation by the installation of third-party software applications. Furthermore, some Palm OS or Windows mobile-based PDAs
Basic functionality
PDAs are shirt-pocket-sized devices with a touch-sensitive screen, a dedicated input area or keyboard, customisable application buttons, and a multiway (button or mini joystick) navigator to browse information on the screen. Depending on the brand and model, some devices feature an expansion slot for memory cards or accessories, a built-in camera, headphone jacks, speaker, microphone, ports for infrared, Bluetooth, or Wi-Fi (Wireless Fidelity), and even built-in GPS (global positioning system)
Applications for health-care professionals
Physicians, nurses, dieticians, medical students and trainees, and other health-care professionals must review an ever-increasing amount of constantly changing information about their patients several times a day and correlate the data with the most recent diagnostic and therapeutic recommendations and management options to make sound decisions. Traditionally, health-care professionals consulted meticulously collected personal notebooks and article cut-outs, white-coat-pocket manuals,
How and where to find medical software for hand-held computers
Several thousands of medical software applications and documents are available for health-care professionals to use. Medical software can be grouped into major categories: standard medical textbooks and manuals adapted for PDAs, PDA-designed medical references, medical dictionaries, drug reference and interaction check programmes, medical calculators, medical prediction rule applets (a Java software component), document readers, medical image viewers, software for medical evidence retrieval,
A personal perspective
As an internist and gastroenterologist, I face the same challenges that all academic physicians do: attending on the wards, clinics, critical care units, and emergency rooms; doing consultations for other specialties; dealing with numerous conferences, administrative work, lecturing, and bedside teaching; being an investigator in clinical trials; mentoring doctoral students; and running a basic science research laboratory, which often hardly fit into those 24 hours, unless one is very
PDA safety and security
Information recording and interchange always raise the question of security and privacy. Overall, PDA security hazards are probably similar to other computers used in hospitals and elsewhere. Catastrophic data loss can only be prevented with regular backups. PDA viruses have been reported for the mobile operating system from Microsoft Windows and also, to a lesser degree, for the Palm operating system. Major security firms are addressing this problem with the development of commercial antivirus
Challenges of current PDA technology and future outlook
Evidence of PDA use and dominance in medical education, clinical practice, and research is still evolving. Most studies available so far have not been randomised, controlled, or are multicentric in design. The fact that physicians can carry an entire shelf of medical reference textbooks on a hand-held computer's memory card does not automatically mean that physicians know their contents or can apply their knowledge appropriately in clinical practice. The increasing incidence of the so-called

Additionally, higher data processing capability of a PDA has a positive impact on healthcare as it offers stronger decision making support for experts in this area (Baumgart, 2005). Decision support capability of a mobile device will increase user satisfaction (Chatterjee et al., 2009).
