ABSTRACT: The feasibility of implementing current medication treatment guidelines
in a community mental health clinic was examined in this cross-sectional and retrospec-
tive study. Specifically, two issues were addressed: 1) could we identify a set of clinical
guidelines whose utilization could be monitored with a routine medical chart review;
and 2) were the requisite data for such a review available in the medical records. An
examination of three sets of published guidelines revealed 5 specific guidelines that
could be operationalized and monitored. Records were reviewed for a random sample
of two-thirds of all patients currently diagnosed with schizophrenia and schizoaffective
disorder (n = 309). Information was collected from the medical record on patient demo-
graphics, diagnosis, duration of illness, symptoms and side effects, and medication
information. Rates of conformance to the 5 guidelines ranged from a high of 97% to a
low of 43%. The use of current guidelines to improve treatment in community clinics
appears to be limited by the deficiencies in the medical record and the structure of
the guidelines themselves. Standardized progress notes and computerized prescribing

The introduction of the atypical antipsychotics ushered in a new era in
patient compliance (Jibson and Tandon, 1998). However, because the
cost of the newer antipsychotics is higher than that of the older conven-
the allocation of limited resources have to be raised (Doherty, 1999).
To ensure that treatment decisions are rational and evidence-based,
professional and government agencies have published clinical practice
guidelines and algorithms for the treatment of severe mental illnesses
(American Psychiatric Association, 1997; Lehman and Steinwachs,
1998a; The Expert Consensus Guideline Series, 1999; Chiles, Miller,
Crismon, Rush, Krasnoff, and Shon, 1999). We examined the feasibility
of operationalizing guidelines and monitoring the use of medication
treatment guidelines in a CMHC. Specifically, we reviewed three na-
tional guidelines and algorithms for schizophrenia (Lehman and Stein-
wachs, 1998a; The Expert Consensus Guideline Series, 1999; Chiles,
Miller, Crismon Rush, Krasnoff, and Shon, 1999) and identified a set of
maintenance treatment recommendations that could be assessed using
data available in a cross-sectional, retrospective chart review. We then
examined the extent to which current pharmacological treatment prac-
tice at the CMHC conformed to those recommendations.
The study was conducted in a small urban CMHC in the Midwest affiliated with a
large university academic medical center. Three hundred and nine patients aged 18
years of age and older and diagnosed with schizophrenia or schizoaffective disorder,
selected randomly from the center’s data bank, comprised the study sample. A trained
research assistant, using a data abstraction form designed for the study, conducted
medical record reviews. Data were collected on patient demographics, diagnosis, dura-
tion of illness, symptoms and side effects, and medication.
We reviewed the recommendations for maintenance pharmacological treatment of
schizophrenia in three sets of national guidelines: the Patient Outcomes Research

Algorithm Project (TMAP; Chiles, Miller, Crismon, Rush, Krasnoff, and Shon 1999),
and the Expert Consensus Guideline series (1999). We identified five recommendations
that could be evaluated using a cross-sectional medical chart review, and for which
the required information was available in at least 50% of the medical records. Each
recommendation was translated into a conformance criterion, which was then applied
to current practices to estimate a conformance rate (Agency for Health Care Policy and

prescribed for acute or maintenance treatment. However, since more than 80% of the
sample had been ill for at least 10 years, we assumed that most patients were on
maintenance doses and created a conformance criterion that assessed whether the
antipsychotic dosages prescribed for patients were between 300–600 mg CPZ equiva-
lents/day. Only those patients prescribed one oral antipsychotic medication were in-
cluded in the assessment.
The PORT study advises that patients with severe TD be offered a trial of clozapine,
while Consensus guidelines recommend that patients with mild TD be switched to
alize these recommendations, we defined severe TD as an AIMS score of ≥3, indicating
that the patient had minimal abnormal movements in at least three parts of the body
or mild to moderate movements in at least one. Mild TD was defined as an AIMS score
of one or two.
A fourth guideline recommends that persons who experience persistent, clinically
significant positive symptoms despite adequate antipsychotic therapy receive a trial of
two or more antipsychotics, adjunctive pharmacotherapy, or clozapine. Since our cross-
sectional methodology provided no information on the use, duration, or outcome of
previous medication trials, we drafted a conformance criterion that examined whether
patients with positive symptoms noted in their medical record were receiving one or
more of the above-recommended treatments.
The PORT guidelines recommend an “ongoing assessment" of the effectiveness/need
for maintenance antipsychotic therapy and anti-parkinsonian agents. The Consensus
guidelines specifically recommended monthly clinic visits for compliant, asymptomatic
we used was whether patients had a clinic visit within four weeks of the chart review,
and an AIMS test within three months (reflecting the CMHC’s own higher standard
for TD assessments).
Of the 309 subjects, 43% were female; 64% were Caucasian and 30%
were African-American. Mean (SD) age was 46.4 (11.9) years (range:

19% with schizoaffective disorder. Mean (SD) duration of illness was

Medical Record Review
Much ofthe clinicalinformation neededto assessguideline conformance
was not documented in the medical record. For example, while the
presence or absence of positive symptoms was noted in three-quarters
of the charts, the presence or absence of negative symptoms was docu-
mented in only 6% (18). This lack of information limited the number of
guidelines that could be evaluated.
Conformance to Guidelines
Conformance rates for the five criteria are listed below:
Criterion 1: 299 (96.8%) of this sample were being treated with an
Criterion 2: Of the 179 prescriptions for monotherapy antipsychotic
treatment, 43% were within the recommended dose range of 300–
600 mg CPZ equivalents/day; 26% were below, and 32% were above
Criterion 3: Of the forty-six patients identified with severe TD, 63.0%
were being treated with an atypical antipsychotic (23.9% with cloz-
apine). Just over one-third (36.4%) of those with mild TD received
either an atypical antipsychotic and/or vitamin E.
Criterion 4: Information regarding the presence or absence of positive
symptoms were present in 83 and absent in 141. Of those with
positive symptoms, 70 (84.3%) were receiving at least one of the
Criterion 5: Just over one-half (54.4%) of the subjects had a clinic
visit within four weeks of data collection; similarly just over half
(54.0%) had an AIMS test within the past three months.
