Older adults recently started on psychotropic medication: where are the symptoms?

OBJECTIVE: The objective of this study is to understand the characteristics of older adults on newly prescribed psychotropic medication with minimal psychiatric symptoms. METHODS: Naturalistic cohort study of non-institutionalized older adults in Pennsylvania participating in the Pharmaceutical Assistance Contract for the Elderly. Persons newly prescribed antidepressant or anxiolytic monotherapy or combination therapy were contacted for clinical assessment by a telephone-based behavioral health service. The initial assessment included standardized mental health screening instruments and scales including the Blessed Orientation-Memory-Concentration test, Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Medical Outcomes Survey (SF-12). In addition, patients were asked for their understanding of the prescription indication. RESULTS: Of the 254 participants who met minimal symptom criteria (Patient Health Questionnaire-9 < 5 and Generalized Anxiety Disorder-7 < 5), women comprised slightly more of the anxiolytic compared with antidepressant monotherapy group (88.9% vs. 76.7%, p = 0.04). The most common self-reported reason for prescription of an antidepressant or anxiolytic was depression or anxiety, respectively, despite near-absence of these symptoms on clinical assessment. Comparing monotherapy to combination therapy groups, those with combination therapy were more likely to report a history of depression (12.6% vs. 1.8%, p < 0.001) and also report depression as the reason for the prescription (40.2% vs. 21.0%, p < 0.01). CONCLUSIONS: In this sample of older adults on new psychotropic medication with minimal psychiatric symptoms, there are few patient characteristics that distinguish those on antidepressant versus anxiolytic monotherapy or those on monotherapy versus combination therapy. While quality of care in late-life mental health has focused on improving detection and treatment, there should be further attention to low-symptom patients potentially receiving inappropriate pharmacotherapy.

Telephone-based care management for older adults initiated on psychotropic medication.

OBJECTIVE: This study aimed to explore the longitudinal, 6-month symptom course of older adults newly started on an antidepressant or anxiolytic by non-psychiatrist physicians and enrolled in a care management program. METHOD: This is a naturalistic cohort study of older adults (age ≥65 years) receiving pharmacotherapy and telephone-based care management. Participants are non-institutionalized adults participating in Pennsylvania's Pharmaceutical Assistance Contract for the Elderly who completed telephone-based clinical assessments including demographic data, self-report on history of psychiatric treatment and adherence, and standardized symptom scales. RESULTS: A total of 162 participants with an average age of 77.2 years (SD 6.8) were followed and, for analysis, split into two groups by PHQ-9 score: 75 (46.3%) scoring 0-4 (minimally symptomatic group, MSG) and 87 (53.7%) scoring ≥5 (symptomatic group, SG). Over 6 months, the SG improved with PHQ-9 scores beginning on average at 10.0 (SD 4.6) and falling to 5.4 (SD 4.2) (F(1, 86) = 29.53, p < 0.0001). The MSG had no significant change in depressive symptoms. Emotional health as measured by SF-12 Mental Composite Score mirrored the PHQ-9 change and lack thereof in the SG and MSG, respectively. No clinical or demographic features were associated with symptom improvement in the SG although they were more likely to report medication adherence (66.7% vs. 44.0%, χ(2) (1) = 8.4, p = 0.0037) compared with the MSG. CONCLUSIONS: Participation of symptomatic older adults initiated on psychotropic medication in a telephone-based care management program was associated with improvement in depressive symptoms and overall emotional well-being, notable findings given participants' advanced age, state-wide distribution, and history of limited utilization of mental health care.

Telephone-based behavioral health assessment for older adults starting a new psychiatric medication.

OBJECTIVES: The purpose of this study is to explore behavioral health symptoms and characteristics of noninstitutionalized older adults newly started on an antidepressant, anxiolytic, or antipsychotic agent by nonpsychiatrist physicians. DESIGN: Naturalistic cohort study of older adults participating in the Pharmaceutical Assistance Contract for the Elderly (PACE) of the state of Pennsylvania. SETTING/PARTICIPANTS: Noninstitutionalized adults in Pennsylvania. MEASUREMENTS: Standardized scales including the Blessed Orientation-Memory-Concentration (BOMC) test, Mini International Neuropsychiatric Interview (including Psychosis, Mania, Generalized Anxiety Disorder [GAD], Panic Disorder, and Alcohol Abuse/Dependence modules), Patient Health Questionnaire-9 (PHQ-9), Paykel Scale for suicide ideation, and Medical Outcomes Survey (SF-12). RESULTS: Participants were mostly women (83.7%) with a mean age of 79.2 years (SD 7.1). The average PHQ-9 score for those on antidepressants was 5.8 (5.2), with no statistically significant difference between medication groups (F[2, 409] = 1.48, p = 0.23); just seven (4.9%) of those receiving anxiolytics met criteria for an anxiety disorder, which was not significantly different than other medication classes (χ (2) = 0.83, p = 0.66). Overall, 197 (47.8%) of the sample did not meet criteria for a mental health disorder. Just 69 (28.8%) of those on antidepressants reported depression as the self-reported reason for taking the medication, while 91 (22.8%) of the total reported poor sleep or stressful life events as the reason. CONCLUSIONS: In this sample, many older persons received psychotropic medications despite low symptomatology, increasing the costs of care and possible exposure to unnecessary side effects. It is important to understand perceived benefit to both patient and provider of such prescribing patterns and work towards minimizing unnecessary use.

Rationale and design of the Study Assessing the Effect of Cardiovascular Medications Provided as Low-cost, Evidence-based Generic Samples (SAMPLES) trial.

BACKGROUND: Highly effective generic cardiovascular medications are frequently underused, leading to greater overall drug costs and cost-related nonadherence. OBJECTIVE: We sought to assess an intervention to stimulate appropriate generic cardiovascular drug use without creating administrative or financial barriers that may impede essential medication use. TRIAL DESIGN: The SAMPLES (Study Assessing the Effect of Cardiovascular Medications Provided as Low-cost, Evidence-based Generic Samples) trial is a clustered, randomized controlled trial of the effect of providing physicians with free generic samples of hydrochlorothiazide for hypertensive patients and simvastatin for patients with hyperlipidemia. We will randomize 660 primary care physicians in Pennsylvania, clustered by physician practice, to receive free samples for both conditions or to receive no samples. We will use data on filled prescriptions obtained from a state-sponsored prescription drug assistance program to perform an intention-to-treat evaluation of the impact of the intervention on physician prescribing behavior (proportion of prescriptions that are generic) and patient adherence. Secondary outcomes will include physician adherence to established guidelines and overall prescription drug costs. CONCLUSION: This trial will define the potential role of an innovative approach to stimulate clinically appropriate cost-effective prescribing. We will determine whether free generic samples can reduce overall drug costs as well as out-of-pocket costs to the patient without sacrificing efficacy and whether this approach results in improved adherence to essential cardiovascular medications. This intervention may also improve adherence to practice guidelines and improve the quality of care received. If effective, this strategy could be used broadly by private insurers or government payers aiming to stimulate more cost-effective and higher-quality care.
