Depression case finding in primary care: a method for the mandates.

The current mandates for depression screening in primary care create a dilemma for clinicians. How should screening be implemented in the face of limited evidence for sustainable strategies for effective depression monitoring and management in primary care. In this article we review the issues surrounding primary care depression screening, and develop the argument for a case-finding strategy that includes careful choice of a single instrument, focused identification of high-risk patients, and systematic monitoring of outcomes. We believe this is a sustainable method that primary care clinicians can implement to address the spirit of current depression screening mandates.

The relationship of guideline-concordant depression treatment and patient adherence to oral diabetes medications.

BACKGROUND: Many patients with diabetes experience depression, yet it is unclear if the treatment of depression in diabetic patients is concordant with national guidelines, and whether appropriate antidepressant use is associated with better diabetes self-care behaviors. OBJECTIVES: The purpose of this study was to (1) determine whether antidepressant medication use for managed care enrollees with type 2 diabetes was concordant with The Agency for Healthcare Research and Quality depression treatment guidelines; and (2) examine the relationship between guideline concordance and oral diabetes medication adherence. METHODS: Retrospective analyses were conducted using medical/pharmacy claims for 2001 from a managed care organization in the midwestern United States. Subjects were adults with type 2 diabetes treated with oral medications only. The subjects were divided into 3 groups: (1) guideline-concordant users of antidepressants; (2) those who received antidepressants not in concordance with the guidelines; and (3) nonusers of antidepressants. Antidepressant users were determined to be in concordance with the acute phase treatment guidelines if they filled at least 90 days supply of antidepressant drugs within 118 days of the first fill. Adherence to diabetes medications was measured by the medication possession ratio. A 1-way analysis of variance with Scheffe's test was used to compare the antihyperglycemic medication possession ratio across the three groups. RESULTS: One hundred eighty-two (12.5%) of the 1454 subjects initiated treatment with antidepressants. Eighty-nine (48.9%) of the 182 antidepressant users were in concordance with the acute phase treatment guidelines. Subjects with subconcordant antidepressant use had a lower mean diabetes medication possession ratio than those with either guideline-concordant use or no use (F=14.3, P<.01). CONCLUSION: Over half of the diabetic patients initiating treatment for depression did not receive therapy in concordance with the Agency for Healthcare Research and Quality guidelines. Patients whose antidepressant use was not concordant with the guidelines were also less adherent to diabetes medications.

The mediating role of health beliefs in the relationship between depressive symptoms and medication adherence in persons with diabetes.

BACKGROUND: Although bivariate relationships between depressive symptoms, health beliefs, and medication adherence have been identified, the complex relationship among these 3 constructs has not been explicated. OBJECTIVE: This study examines the mediating role of patients' beliefs about diabetes and diabetes medications in relation to depressive symptoms and diabetes medication adherence. METHODS: A survey was sent to 1700 persons with type 2 diabetes who were enrolled in a managed care organization in the United States. The bivariate relationships between depressive symptoms, diabetes-related health beliefs, and diabetes medication adherence were assessed. A structural equation model was developed to determine if health beliefs mediated the relationship between depressive symptoms and medication adherence. RESULTS: Usable responses were received from 445 subjects. Greater depressive symptoms were associated with lower adherence to diabetes medications. The structural equation model indicated that the effect of depressive symptoms on medication adherence was mediated through perceived side effect barriers, perceived general barriers, and self-efficacy. Patients with severe depressive symptoms perceived more barriers to treatment adherence and were less confident in their ability to adhere to medication. In turn, reduced self-efficacy and heightened perceived barriers had a negative association with patients' adherence to diabetes medication regimens. CONCLUSIONS: Decreased adherence to diabetes medications in patients with both diabetes and depressive symptoms may be partly explained by the association of depression with patients' beliefs about diabetes medications and their self-efficacy for medication use.

Severity and criteria based prompting for treatment of depressed patients.

PURPOSE: Primary care physicians (PCPs) often do not respond to prompts based upon criteria-based depression screens, perhaps because these prompts do not account for depression severity. We conducted this pilot study to determine the feasibility of prompting for both diagnostic criteria and severity and to assess whether depression would be more attended to with positive "dual prompts" than prompts based on either criteria or symptom severity alone. METHODS: Immediately prior to a routine care appointment, 87 adults from three primary care practices completed the PRIME-MD Clinician Evaluation Guide Mood Module (PRIME-MD; assesses depression criteria) and the Brief Depression Rating (BDR; assesses depressive symptom severity), and their results were issued in a salient PCP prompt on the chart. Immediately afterwards, patients reported the impact of the screening results upon treatment decisions during the encounter. Data were analyzed by X2, analysis of variance, and binomial regression. RESULTS: Compared to subjects screening positive on either depression criteria or severity alone (n = 10), those patients on both (n = 17) were more likely to report discussing depression, and agreement that the physician and patient decided treatment was needed and initiated or continued. There were no differences in patient satisfaction based on screening results. After accounting for PRIME-MD results, BDR scores predicted agreement with the physician and patient decided treatment was needed (OR = 22.03; 95% CI: 2.05-236.46). CONCLUSIONS: Supplementary severity-based depression screening is feasible, and might overcome the limitations of criteria-based screening alone. Future research could test this hypothesis in a large randomized trial.

Toward cost-effectiveness analysis in the diagnosis and treatment of insomnia.

Insomnia is believed to have high prevalence, cost, and impact. However, comprehensive cost-effectiveness analyses (CEAs) of different diagnostic and treatment strategies have not been performed. Part of the reason is that limited data are available on prevalence, costs, and outcomes, each of which is key elements of any CEA. The authors conducted a MEDLINE search to review available literature. Epidemiological surveys have yielded variable results, depending on operational definitions and populations studied. Cost estimates have varied widely depending on whether indirect costs are included and which costs are considered. Impact on health-related quality of life appears to be substantial, but effects on utility scores-necessary to compare cost-effectiveness of insomnia management to that of other health care interventions-have not been reported. Furthermore, much of the data on health-related quality of life is cross-sectional, and cannot be used to test whether the identified associations are causal. The authors conclude that effective insomnia management holds promise as a cost-effective health care intervention. However, the CEA models that eventually may support this hypothesis will require accurate measures of direct and indirect costs, health state utility in treated and untreated insomnia, and prevalence data based on widely-accepted case definitions.

The effects of sleep loss and fatigue on resident-physicians: a multi-institutional, mixed-method study.

PURPOSE: To identify and model the effects of sleep loss and fatigue on resident-physicians' professional lives and personal well-being. METHOD: In 2001-02, 149 residents at five U.S. academic health centers and from six specialties (obstetrics-gynecology, emergency medicine, family medicine, internal medicine, pediatrics, surgery) were recruited for the study. Residents were all in good standing in their programs. In a mixed-methods design, focus groups consisted of an average of seven (range, three to 14) individuals in the same year of training and residency program, for a total of 60 interns and 89 senior residents. Trained moderators conducted focus groups using a standardized, semistructured discussion guide. Participants also completed a 30-item quantitative questionnaire assessing sleepiness and workplace sleep attitudes that included the Epworth Sleepiness Scale (ESS). RESULTS: Residents described multiple adverse effects of sleep loss and fatigue on learning and cognition; job performance, including professionalism and task performance; and personal life, including personal well-being and relationships with spouse or significant other and family. Only 16% of the sample scored within the "normal" range on the ESS; 84% scored in the range for which clinical intervention is indicated. Sleepiness was consistent across institution, specialty, years of training, age, gender, marital status, and having children. CONCLUSIONS: More residents perceived that sleep loss and fatigue had major impact on their personal lives during residency, leaving many personal and social activities and meaningful personal pleasures deferred or postponed. Sleep loss and fatigue also had major impact on residents' abilities to perform their work. This finding further substantiates the growing concern about the potential impact on professional development. These observations should be taken into account in developing new training guidelines and educational interventions for housestaff.

The concordance of self-report with other measures of medication adherence: a summary of the literature.

OBJECTIVE: The objective of this study was to evaluate the concordance of self-report measures of medication adherence (interview, diary, or questionnaire) with nonself-report measures of adherence (administrative claims, pill count or canister weight, plasma drug concentration, electronic monitors, or clinical opinion). METHODS: A literature search was conducted to identify published reports in which self-report and nonself-report measures of adherence were used within the same study. The concordance of measures within each study was categorized as high, moderate, or low based on a comparison of the adherence estimates. RESULTS: Eight-six comparisons of self-report to nonself-report measures of adherence were identified. Thirty-seven of the 86 comparisons (43%) were categorized as highly concordant. However, concordance varied substantially by type of self-report measure and nonself-report measure. Self-report measures, in general, were highly concordant with electronic measures in only 17% of comparisons, whereas they were highly concordant with other types of nonself-report measures in 58% of comparisons (chi-square = 14.30, P <0.01). When comparing self-report measures, interviews had significantly lower concordance with nonself-report measures as compared with questionnaires or diaries (chi-square = 8.47, P = 0.01). In 15 comparisons of interviews with electronic measures, none of the comparisons were highly concordant, whereas questionnaires and diaries had moderate-to-high concordance with electronic measures in 12 of 16 comparisons (75%). CONCLUSIONS: The concordance of self-report and other measures of medication adherence varies widely based on the type of measures used. Questionnaires and diaries tend to have moderate-to-high concordance with other measures of medication adherence. However, interview-based self-reports are not concordant with electronic measures. Questionnaire and diary methods could be preferable to interviews for self-reported medication adherence.

Depressive symptoms among women with vulvar dysesthesia.

OBJECTIVE: The purpose of this study was to determine whether vulvar dysesthesia is associated with elevated depressive symptoms. STUDY DESIGN: This was a cross-sectional case-control study of women who underwent treatment of vulvar dysesthesia (n=32) or who were seen for a routine gynecologic examination (n=32). Subjects completed measures of depressive symptoms and pain and a sexual and medical history. Multivariate and univariate analyses were conducted. RESULTS: Analyses that were adjusted for age, education, and medical conditions indicated that vulvar dysesthesia was associated positively with depressive symptoms (P=.002). However, this was attributable to the somatic (P=.002) rather than cognitive-affective symptoms (P=.16) of depression, partially related to the endorsement of sexual disinterest, and mediated by pain reports. CONCLUSION: Vulvar dysesthesia is associated with elevated depressive symptom severity, although not to the extent that indicates probable depressive disorder. In this condition, depressive symptoms are likely to be a measurement artifact, rather than a depressive process. Certain depressive symptoms (eg, sexual disinterest) directly inflate depression estimates in this patient group.

Diabetes and driving mishaps: frequency and correlations from a multinational survey.

OBJECTIVE: The intensive treatment of diabetes to achieve strict glycemic control is a common clinical goal, but it is associated with an increased incidence of hypoglycemia. Becoming hypoglycemic while driving is a hazardous condition and may lead to a greater incidence of driving mishaps. This study investigated whether diabetes is associated with increased risk of driving mishaps and correlates of such a relationship. RESEARCH DESIGN AND METHODS: During routine visits to diabetes specialty clinics in seven U.S. and four European cities, consecutive adults with type 1 diabetes, type 2 diabetes, and nondiabetic spouse control subjects (n = 341, 332, and 363, respectively) completed an anonymous questionnaire concerning diabetes and driving. RESULTS: Type 1 diabetic drivers reported significantly more crashes, moving violations, episodes of hypoglycemic stupor, required assistance, and mild hypoglycemia while driving as compared with type 2 diabetic drivers or spouse control subjects (P < 0.01-0.001). Type 2 diabetic drivers had driving mishap rates similar to nondiabetic spouses, and the use of insulin or oral agents for treatment had no effect on the occurrence of driving mishaps. Crashes among type 1 diabetic drivers were associated with more frequent episodes of hypoglycemic stupor while driving, less frequent blood glucose monitoring before driving, and the use of insulin injection therapy as compared with pump therapy. One-half of the type 1 diabetic drivers and three-quarters of the type 2 diabetic drivers had never discussed hypoglycemia and driving with their physicians. CONCLUSIONS: Type 1 diabetic drivers are at increased risk for driving mishaps, but type 2 diabetic drivers, even on insulin, appear not to be at a higher risk than nondiabetic individuals. Clinical and treatment factors appear to increase risk, e.g., more frequent hypoglycemia while driving, method of insulin delivery, and infrequent self-testing before driving. Physicians are encouraged to talk to their type 1 diabetic patients about hypoglycemia and driving.

Nine-month predictors and outcomes of SSRI antidepressant continuation in primary care.

BACKGROUND: This study aimed to identify the predictors and outcomes of SSRI antidepressant continuation, discontinuation and switching over a 9-month period of naturalistic observation. METHODS: Primary care patients (n=573) with physician-diagnosed depression from 37 practices were randomized to an open-label trial of one of three selective serotonin reuptake inhibitors (SSRIs) managed in their primary care setting. Psychiatric characteristics and treatment course were assessed at baseline and at 1, 3, 6 and 9 months after medication initiation. RESULTS: Nineteen percent of patients switched SSRIs, which occurred significantly sooner than discontinuation (median: 41 vs.100 days). Time to discontinuation was primarily explained by baseline patient skepticism about taking an antidepressant (62% increase in discontinuation risk). In contrast, time to switch was associated with greater impairment at baseline and lesser improvement in impairment during the first month on medication. Patients who discontinued were significantly less likely to be depressed 9 months after starting medication than those who either continued or switched medication, and were less symptomatic and impaired than patients who switched. CONCLUSIONS: Baseline impairment may increase the risk for SSRI antidepressant switching. Additionally, patient skepticism about antidepressants predicts early SSRI discontinuation and may predict rapid recovery. Intent-to-treat analyses in nonrandomized clinical trials may paradoxically inflate antidepressant effect sizes.

Patient-provider communication and self-care behavior among type 2 diabetes patients.

PURPOSE: The purpose of this study was to determine whether diabetes self-care behaviors mediate the association between patient-provider communication (PPC) and diabetes outcomes. METHODS: An ethnically diverse sample of 752 patients with type 2 diabetes was recruited from 3 different health systems. Subjects were interviewed by telephone about their general and diabetes-specific PPC, diabetes self-care behaviors (medication use, glucose testing, eating, and physical activity), and functional status (physical and mental). Glycemic control was assessed with the HbA1c assay. Statistical tests of the hypothetical path model were adjusted for age, gender, marital status, income, ethnicity, medication regimen, and number of comorbid conditions. RESULTS: General PPC was associated with mental functioning and physical functioning, and diabetes-specific PPC was associated with glycemic control. However, these associations were not mediated by self-care behaviors, which were independently associated with diabetes outcomes. CONCLUSIONS: Although self-care and PPC are both important determinants of diabetes patients' health status, these effects are independent. Thus, attempts to improve diabetes outcomes must focus on both good communication and the direct enhancement of illness self-management behaviors.

Adherence to maintenance-phase antidepressant medication as a function of patient beliefs about medication.

PURPOSE: This study aimed to identify the demographic, psychiatric, and attitudinal predictors of treatment adherence during the maintenance phase of antidepressant treatment, ie, after symptoms and regimen are stabilized. METHODS: We surveyed 81 primary care patients given maintenance antidepressant medications regarding general adherence, recent missed doses, depression and treatment features, medication beliefs (necessity, concerns, harmfulness, and overprescription), and other variables. Additional data were collected from medical and payer records. RESULTS: Median treatment duration was 75 weeks. Adherence and beliefs were broadly dispersed and unrelated to treatment duration and type, physical functioning, and demographics. Multivariate analysis adjusting for social desirability, depression severity, and treatment duration indicated that an antidepressant-specific "necessity-minus-concerns" composite was strongly associated with both adherence outcomes. Specifically, adherence was highest when necessity exceeded concerns and lowest when concerns exceeded necessity. We crossed these 2 dimensions to characterize 4 patient attitudes toward antidepressants: skepticism, indifference, ambivalence, and acceptance. CONCLUSIONS: Patients given maintenance antidepressants vary widely in adherence. This variation is primarily explained by the balance between their perceptions of need and harmfulness of antidepressant medication, in that adherence is lowest when perceived harm exceeds perceived need, and highest when perceived need exceeds perceived harm. We speculate on ways to tailor adherence strategies to patient beliefs. Subsequent research should determine whether patients' perceptions about medication predict depression outcomes, can be used to improve clinical management, and respond to behavioral intervention.

Help-seeking for insomnia among adult patients in primary care.

OBJECTIVE: To clarify the patient characteristics associated with seeking medical help for insomnia. METHODS: A consecutive sample (n = 700) of adults attending a non-urgent primary care appointment was screened for sleep problems. A follow-up mailed survey then assessed insomnia symptoms, daytime impairment, beliefs about sleep, medication use, sleepiness and fatigue, and medical help-seeking. RESULTS: Fifty-two percent of patients with probable insomnia reported discussing this with a physician. Multivariate logistic regression analyses indicated that discussing one's probable insomnia with a physician was independently associated with having a greater number of medical conditions (OR, 2.19 [95% CI, 1.13 to 4.22]), being more highly educated (1.67 [95% CI, 1.11 to 2.51]), sleeping less per night (OR, 0.71 [95% CI, 0.52 to 0.96]), and greater perceived daytime impairment due to insomnia (OR, 2.07 [95% CI, 1.06 to 4.03]). CONCLUSIONS: Primary care patients often seek medical help when they experience insomnia. Clinical treatment ought to especially target poor sleepers presenting with significant insomnia-related impairment, medical morbidity, or both. Future research should further clarify the role of medical and psychiatric comorbidities and determine whether resolution of insomnia and its consequences improves the outcomes of common medical conditions.

Assessment of depressive symptoms in deaf persons.

BACKGROUND: Evidence suggests that Deaf people may have a greater prevalence of depressive symptoms. However, it is unclear whether commonly used written screening instruments are accurate with this population because of their unique cultural and linguistic factors. SETTING: Deaf persons (n = 71) residing in southeastern Michigan. METHODS: Subjects completed the Zung Self-Rated Depression Scale in both the written (ZSDS-W) and American Sign Language (ZSDS-S) formats and the Hamilton Depression Scale (HAM-D) in American Sign Language in counterbalanced order, followed by a Test Of Reading Comprehension (TORC). They also provided extensive data on demographic, hearing loss, language use, social and health care use variables. RESULTS: Mean subject age was 52 years, 63% of subjects were women, 95% were Caucasian, and 47% were married (87% to another deaf/hard of hearing person). Thirty percent had a college degree and 20% had less than a 10th grade education. The ZSDS-W and ZSDS-S scores were highly correlated (r = +0.79), although the mean ZSDS-W score was 2.8 points higher (P = .001). The ZSDS-S correlated more highly (r = 0.80) with the HAM-D than the ZSDS-W (r = 0.71). There was a significant interaction effect (P < .001) such that the ZSDS-W and HAM-D were significantly associated among higher literacy subjects (beta = 0.80, P < .001) but not lower literacy subjects (beta = 0.20, P = .183). There were no other significant associations between depression scores and numerous demographic, educational, hearing loss, social or language variables. CONCLUSIONS: Compared with the conventional ZSDS-W, the ZSDS-S more accurately assesses depression severity among deaf persons with lower English literacy. However, given the greater sensitivity of the ZSDS-W and the practical barriers to ZSDS-S in physician practices, further research should determine which modality is best for routine depression screening.
