Enabling the diagnosis of occult psychiatric illness in the emergency department: a randomized, controlled trial of the computerized, self-administered PRIME-MD diagnostic system.

STUDY OBJECTIVE: Undiagnosed mental illness is highly prevalent and produces needless morbidity. Emergency department patients with vague or longstanding complaints are at risk for occult mental illness, but are seldom diagnosed. We conducted this study to determine whether a previously validated, self-administered, computerized psychiatric interview (Primary Care Evaluation of Mental Disorders [PRIME-MD]) could increase the detection of occult psychiatric illness in the ED. METHODS: This was a randomized, controlled trial of consecutive patients enrolled during convenient times at a university teaching hospital ED with an annual census of 38,000. ED house staff and attending physicians participated. Patients were those with nonspecific complaints potentially associated with occult psychiatric illness (eg, long-standing headache, abdominal or back pain). Exclusion criteria were known psychiatric illness, complaint, or medication; and straightforward reason for the ED visit. Consenting subjects completed the PRIME-MD questionnaire in the waiting room, and were randomly assigned to either the "report" (report results given to physician) or "no-report" groups. PRIME-MD results were clipped to the front of the chart of report group patients. There was no other intervention. The main outcome measures were the percentage of all patients and percentage of patients with a PRIME-MD diagnosis who received a psychiatric diagnosis, consultation, or referral from the emergency physician. RESULTS: A total of 339 (5.1%) of all patients were approached; 230 consented to participate in the study, and 218 completed the PRIME-MD session and were randomly assigned to study groups. Ninety-two patients in the report group and 98 cases in the no-report group were analyzed. Patients were omitted for the following reasons: left without being seen (8), mistakenly enrolled (10), or unretrievable medical records (10). Seventy-nine (42%) patients received a psychiatric diagnosis from PRIME-MD and 9 (5%) from the physician. The frequencies of physician psychiatric diagnosis and referral did not differ between groups (diagnosis: report 9%, no report 9%, Delta 0%, 95% confidence interval [CI] -13, 14; referral: report 9%, no report 7%, Delta 2%, 95% CI -11, 16). CONCLUSION: ED patients willingly completed the PRIME-MD questionnaire (in a median time of 7 minutes), which frequently diagnosed psychiatric conditions. Despite this, physicians rarely diagnosed or treated these conditions regardless of whether they were provided with the PRIME-MD diagnoses.

Clinical care management and workflow by episodes.

This paper describes the implementation of clinically defined episodes of care and the introduction of an episode-based summary list of patient problems across Mayo Clinic Rochester in 1996 and 1997. Although Mayo's traditional paper-based system has always relied on a type of 'episode of care' (called the "registration") for patient and history management, a new, more clinically relevant definition of episode of care was put into practice in November 1996. This was done to improve care management and operational processes and to provide a basic construct for the electronic medical record. Also since November 1996, a computer-generated summary list of patient problems, the "Master Sheet Summary Report," organized by episode, has been placed in all patient histories. In the third quarter of 1997, the ability to view the episode-based problem summary online was made available to the 3000+ EMR-capable workstations deployed across the Mayo Rochester campus. In addition, the clinically oriented problem summarization process produces an improved basic "package" of clinical information expected to lead to improved analytic decision support, outcomes analysis and epidemiological research.

Development of a clinical data architecture.

This paper presents a methodology for developing a data architecture for clinical medicine. The methodology uses an object-oriented analysis approach that takes advantage of the domain expertise of practicing physicians. The resulting high-level data model combines a structured, event-based model of clinical information with the process-oriented structures usually associated with problem lists and practice protocols.

Coordinated delivery of clinical care: the "re-integration" of the medical group practice.

This paper suggests that for medical knowledge to be effective, it must be reliably translated into a series of synchronized activities, both clinical and operational. The goal of medical information science must be not only to identify the best course of care, but also through the use of systems for the ordering, scheduling, and deployment of staff and resources to assure that the planned course of care is reliably and efficiently delivered in actual practice settings. We present a brief history of several innovations in patient care coordination and logistics at Mayo Clinic to provide background for the main concepts presented. The principle of patient care coordination underlying this history of innovation is shown to have evolved into a new need for information systems capable of proactively effecting the delivery of care through patient, staff and resource deployment and monitoring.

A system for reporting gynecologic procedures. A linguistic-logical approach.

A system was developed for reporting gynecologic procedures at Chicago Lying-In Hospital. The system is designed to report procedures and treatments performed during both inpatient stays and outpatient visits. Key features of the system are (1) the automatic encoding of all gynecologic procedures in both the ICD (International Classification of Diseases) and CPT (Current Procedural Terminology) coding systems, (2) the use of an independent program to maintain and update a multiply referenced network of operative procedures and (3) the use of a cross-indexing system that allows each procedure to be accessed in several ways and according to several patterns of keys (billing code number, CPT category, common abbreviation and/or linguistic feature).
