[Recognizing borderline intellectual functioning or mild intellectual disability in newly registered patients in a general psychiatric outpatient clinic].

It is unclear whether borderline intellectual functioning (bif) and/or a mild intellectual disability (mid) in patients receiving treatment in mental health care are being recognized by care providers.<br/> AIM: Exploratory study to register under-diagnosis of bif/mid in an outpatient clinic.<br/> METHOD: The number of patients diagnosed with bif/mid according to the electronic patient file (epd) was determined. From 11 August to 11 December 2015, all newly registered patients for outpatient treatment with an mbo-2 or lower educational level were screened for the possible presence of bif/mid applying the screener for intelligence and mild intellectual disability (scil). For all patients, their mental health care practitioner was asked if they suspected bif/mid. These percentages were compared. The sensitivity and specificity and the positive and negative predictive value (ppv and npv) of the opinion of the mental health care practitioners were determined.<br/> RESULTS: In the epd 2,8% of patients were diagnosed with bif, and 0,8% with mid. The percentage of suspected bif/mid of newly registered patients was 17,5%. The sensitivity of the assessors' opinion was 41%, the npv was 57%.<br/> CONCLUSION: In newly registered patients at an outpatient clinic bif and mid are important but frequently missed co-morbidities.
