In a previous study, a checklist and a schema for operationalized interventions have been described . In this study, these operationalized interventions have been used in clinical practice in 820 cases. In 287 cases (35%), recommendations focusing on the medical treatment, other than diagnostic action (41%) and medication (68%), were provided. This emphasis on the intensity of medical treatment is an unreported finding. The further distribution of recommendations over the different intervention domains was: obtaining additional psychosocial information, 30%; psychosocial management on the ward, 61%, specifically its organization; discharge planning, 41%; and aftercare management, 24%. Recommendations infrequently used included: monitoring of cognition and behavior, referrals to occupational therapy and alcohol- and drug-related facilities, and a detailed specification of postdischarge care. Since consultee concordance with the consultant's recommendations is important to treatment outcome, this method of a systematic recording of operationalized recommendations is a first step toward enhancing the evaluation of treatment recommended and provided by consultation/liaison (C/L) psychiatrists. Moreover, these operationalized recommendations help advance the specification of protocols for psychiatric intervention studies.
