Most parents can tell you the first time their baby smiled, or took his or her first step. But what about the first time a baby could adjust his or her gaze to look in the direction of a pointed finger, which an inability to do at a certain age indicates a possible risk of autism?
Paediatricians often ask parents to complete medical charts that record six categories of developmental milestones from birth to age five. Tracking this information may help with earlier diagnosis of conditions such as speech delays, autism and hearing or visual impairment.
"So much of the medical literature shows that the quality of decision making and diagnosis really depends on the amount of data that doctors have", stated Julie Kientz, whose research focuses on technology for medical and educational record-keeping.
In a perfect world, parents would record milestones as soon as they were observed. In the real world, busy parents often fill out records before each check-up - sometimes in the doctor's office parking lot. "Parents are busy, they have a lot going on in their life. Even though they have a lot of good intentions, the time between visits goes by very quickly", Julie Kientz stated.
Baby Steps encourages participation by adding social incentives. Researchers tested the system with eight families over three months. Four families were given a computer system designed strictly for medical record-keeping. The other four families used a more elaborate system with added features such as a keepsake album, pop-up reminders and e-mail alerts, tools to print or e-mail newsletters, as well as a button to create a report for the doctor's visit.
Adding sentimental functions caused parents to use the system three times more frequently, uploading three times as many pictures and videos and ultimately recording twice as many developmental milestones. Parents also reported enjoying the Baby Steps system more.
On top of the high-tech scrapbook tools, researchers built a wireless video camera with a time-lapse save function to help record events, similar to how a digital video recorder works. Parents set up the camera where their child plays, and if the child does something new, parents can press the camera's button and save footage of what just happened. Otherwise, the camera keeps rolling and footage older than 20 minutes is deleted. The videos can then be easily synchronized with a child's records.
"Kids do unpredictable things, and usually when they do these things you don't have a camera running. By the time you go and grab a camera they fall down, they're crying, or they've moved on to something else. We tried to find a way to help capture those moments", Julie Kientz stated.
Baby Steps lets parents share these videos with family and friends by e-mail or by posting to YouTube. Parents can also bring the video camera to the doctor's office. Doctors reported that parents using Baby Steps seemed much better prepared and more confident during their well-child visits.
Julie Kientz hopes to modify the tool so it requires less expensive electronics, perhaps running entirely on a cell phone, so families would not need a personal computer and high-speed Internet connection to use the system.
Baby Steps mimics some of the functions of popular baby-centred sites such as Tumblon.com, BabyAlbum.com and BabyCenter.com. Julie Kientz said parents would likely also benefit from those sites because they incorporate many of the same features, though the medical goals are not yet as closely integrated in the commercial ventures.
The research was funded by a grant from the National Science Foundation. Experts at the Centers for Disease Control were consulted about the design, and the researchers are looking for a partner to manufacture and distribute the system commercially.
