title: Evaluation of covert video surveillance in the diagnosis of munchausen syndrome by proxy: lessons from 41 cases.
abstract: OBJECTIVE
  In 1993, Children's Healthcare of Atlanta at Scottish Rite (formery Scottish Rite Children's Medical Center, Atlanta, GA) added facilities to perform inpatient covert video surveillance (CVS) of suspected cases of Munchausen syndrome by proxy (MSBP). Forty-one patients were monitored from 1993 to 1997. This study was performed to review our experience with these cases. How useful was video surveillance in making the diagnosis? What were the characteristics of families with children who were victims of MSBP?
  
  
  METHODS
  Medical, social work, security, and administrative records of all children who underwent covert video monitoring at Children's Healthcare of Atlanta at Scottish Rite from 1993 through 1997 were reviewed retrospectively by a team of physicians, risk managers, and social workers.
  
  
  RESULTS
  A diagnosis of MSBP was made in 23 of 41 patients monitored. CVS was required to make the diagnosis in 13 (56.1%) of these 23, and supportive of the diagnosis in 5 (21.7%) cases. In 4 patients, this surveillance was instrumental in establishing innocence of the parents. MSBP was more common in Caucasian patients than in other ethnic groups seen at our hospital. Fifty-five percent of mothers gave a history of health care work or study, and another 25% had previously worked in day care. Although many of caretakers fit the profile of MSBP, such as excessive familiarity with medical staff, eagerness for invasive medical testing, and history of health care work, these characteristics were not sensitive indicators of MSBP in our study. Even when present, they were not sufficiently compelling to make the diagnosis.
  
  
  CONCLUSIONS
  CVS is required to make a definitive and timely diagnosis in most cases of MSBP. Without this medical diagnostic tool, many cases will go undetected, placing children at risk. All tertiary care children's hospitals should develop facilities to perform CVS in suspected cases.
