The use of psychotropics in the medically ill

Psychiatric comorbidity among terminally ill patients in general practice in the Netherlands: a comparison between patients with cancer and heart failure

BACKGROUND

It is unclear whether psychiatric disorders are specifically related to the terminal phase of cancer, or independent of the underlying disease.

AIM

To investigate the rate of psychiatric comorbidity and psychotropic drugs prescription in terminally ill patients in the GP setting, comparing both patients with terminal cancer and heart failure.

DESIGN AND SETTING

Retrospective cohort study using the Utrecht General Practitioner Research Network.

METHOD

Equally-sized groups of patients with terminal cancer and heart failure were randomly selected from the database of four general practices over the years 2005-2009. Psychiatric comorbidities were determined using the International Classification for Primary Care (ICPC) codes and psychotropic drugs prescriptions using the Anatomical Therapeutic Chemical (ATC) Classification System codes.

RESULTS

A total of 191 terminally ill patients were included in the study (111 with cancer and 80 with heart failure). The mean age for patients with terminal cancer (70.8 years, standard deviation [SD] = 12.8) was 15 years younger than that of patients with heart failure (85.6 years, SD = 9.2). Half of the terminally ill patients (50.3 %) were prescribed psychotropics, but only 13.6% of them had obtained a psychiatric diagnosis. There were no significant differences in prevalence of psychiatric disease and psychotropic drug prescription between patients with terminal cancer and heart failure.

CONCLUSION

The results demonstrate a high use of psychotropic drugs in terminally ill patients, often in the absence of a formal diagnosis of a psychiatric disorder. The absence of differences between patients with cancer and heart failure suggests that psychiatric diagnoses and increased psychotropic prescriptions are primarily related to the terminal stage of the disease and not to the background of cancer or heart failure.

Factors influencing psychotropic prescription by non-psychiatrist physicians in a nursing home for the elderly in Brazil

CONTEXT AND OBJECTIVE

Although psychotropics are one of the classes of medications most prescribed in nursing homes for the elderly, studies examining prescribing patterns are limited in both number and scope. The present study was undertaken to investigate factors associated with general psychotropic use in a nursing home in Brazil.

DESIGN AND SETTING

Retrospective observational study at the Nursing Home for the Elderly, Institute of Biosciences, Universidade Estadual Paulista.

METHODS

Information on prescriptions was retrieved from the medical records of 108 elderly residents in a nursing home. Sixty-five of these patients, with mean age 74.5 years (+/-standard deviation 9.4 years), who were taking medications on a regular basis, comprised the sample. The effects of demographic and clinical variables on the psychotropic prescription pattern were examined.

RESULTS

Females were more likely to receive psychotropics (p = 0.038). Individuals on medicines for cardiovascular diseases received psychotropics less frequently (p = 0.001). The number of prescribed psychotropics correlated negatively with both age (p = 0.009) and number of non-psychotropic drugs (p = 0.009).

CONCLUSIONS

Although preliminary, the present results indicated that cardiovascular disease was the clinical variable that most influenced psychotropic prescription. Physicians' overconcern regarding drug interactions might at least partially explain this result. Further investigations involving larger sample sizes from different regions are warranted to confirm these findings.

Psychotic symptoms in patients with medical disorders

Psychotic symptoms frequently occur in patients with comorbid medical disorders and present a diagnostic and treatment challenge. They may be a part of an independent psychiatric illness associated with the underlying medical condition or induced by substance use or medications. The presence of psychotic symptoms can contribute to misdiagnosis or complicate the management of the comorbid medical illness. Psychiatrists must be familiar with the assessment and management of psychotic disorders in patients with comorbid medical disorders. Medications that may be used to treat psychosis include antipsychotic agents, benzodiazepines, or possibly certain anticonvulsants. Selecting the appropriate medication requires knowledge of the pharmacokinetics of different agents and their side effect profile. Understanding the neuropsychiatric effects of medications and drug-drug interactions may help in preventing psychotic symptoms.
