The Use of Social Media in Recruitment for Medical Research Studies
BACKGROUND: Recruiting an adequate number of participants into medical research studies is challenging for many researchers. Over the past 10 years, the use of social media websites has increased in the general population. Consequently, social media websites are a new, powerful method for recruiting participants into such studies. OBJECTIVE: The objective was to answer the following questions: (1) Is the use of social media more effective at rese…
Timeliness of Pediatric Influenza Vaccination Compared With Seasonal Influenza Activity in an Urban Community, 2004–2008
Objectives. We assessed pediatric influenza vaccination in relation to community influenza activity. Methods. We examined seasonal influenza vaccination in 34 012 children aged 6 months through 18 years from 5 academically affiliated clinics in northern Manhattan, New York (an urban low-income community) during the 2004–2008 seasons using hospital and city immunization registries. We calculated the cumulative number of administered influenza vacc…

Objectives. We conducted 2 studies to determine the impact of text message immunization reminder–recalls in an urban, low-income population. Methods. In 1 study, text message immunization reminders were sent to a random sample of parents (n = 195) whose children aged 11 to 18 years needed either or both meningococcal (MCV4) and tetanus–diphtheria–acellular pertussis (Tdap) immunizations. We compared receipt of MCV4 or Tdap at 4, 12, and 24 weeks …
Changes in Tdap and MCV4 Vaccine Coverage Following Enactment of a Statewide Requirement of Tdap Vaccination for Entry Into Sixth Grade
Objectives. We evaluated changes in tetanus toxoid, reduced diptheria toxoid, acellular pertussis (Tdap), and tetravalen meningococcal (MCV4) vaccine coverage following enactment of a New York State mandate requiring Tdap before entering sixth grade. Methods. Using data from a hospital-based immunization registry, we measured Tdap and MCV4 coverage among youths aged 11 to 14 years in New York City at 3 time points: premandate, mandate year 1, and…
