Abstract: OBJECTIVES: The aim of this study was to determine both the clinical and cost-effectiveness of usual general practitioner (GP) care compared with two types of brief psychological therapy (non-directive counselling and cognitive-behaviour therapy) in the management of depression as well as mixed anxiety and depression in the primary care setting. DESIGN: The design was principally a pragmatic randomised controlled trial, but was accompanied by two additional allocation methods allowing patient preference: the option of a specific choice of treatment (preference allocation) and the option to be randomised between the psychological therapies only. Of the 464 patients allocated to the three treatments, 197 were randomised between the three treatments, 137 chose a specific treatment, and 130 were randomised between the psychological therapies only. The patients underwent follow-up assessments at 4 and 12 months. SETTING: The study was conducted in 24 general practices in Greater Manchester and London. SUBJECTS: A total of 464 eligible patients, aged 18 years and over, were referred by 73 GPs and allocated to one of the psychological therapies or usual GP care for depressive symptoms. INTERVENTIONS: The interventions consisted of brief psychological therapy (12 sessions maximum) or usual GP care. Non-directive counselling was provided by counsellors who were qualified for accreditation by the British Association for Counselling. Cognitive-behaviour therapy was provided by clinical psychologists who were qualified for accreditation by the British Association for Behavioural and Cognitive Psychotherapies. Usual GP care included discussions with patients and the prescription of medication, but GPs were asked to refrain from referring patients for psychological intervention for at least 4 months. Most therapy sessions took place on a weekly basis in the general practices. By the 12-month follow-up, GP care in some cases did include referral to mental healthcare specialists. MAIN OUTCOME MEASURES: The clinical outcomes included depressive symptoms, general psychiatric symptoms, social function and patient satisfaction. The economic outcomes included direct and indirect costs and quality of life. Assessments were carried out at baseline during face-to-face interviews as well as at 4 and 12 months in person or by post. RESULTS: At 4 months, both psychological therapies had reduced depressive symptoms to a significantly greater extent than usual GP care. Patients in the psychological therapy groups exhibited mean scores on the Beck Depression Inventory that were 4-5 points lower than the mean score of patients in the usual GP care group, a difference that was also clinically significant. These differences did not generalize to other measures of outcome. There was no significant difference in outcome between the two psychological therapies when they were compared directly using all 260 patients randomised to a psychological therapy by either randomised allocation method. At 12 months, the patients in all three groups had improved to the same extent. The lack of a significant difference between the treatment groups at this point resulted from greater improvement of the patients in the GP care group between the 4- and 12-month follow-ups. At 4 months, patients in both psychological therapy groups were more satisfied with their treatment than those in the usual GP care group. However, by 12 months, patients who had received non-directive counselling were more satisfied than those in either of the other two groups. There were few differences in the baseline characteristics of patients who were randomised or expressed a treatment preference, and no differences in outcome between these patients. Similar outcomes were found for patients who chose either psychological therapy. Again, there were no significant differences between the two groups at 4 or 12 months. Patients who chose counselling were more satisfied with treatment than those who chose c

Randomised controlled trial to determine the clinical effectiveness and cost-effectiveness of selective serotonin reuptake inhibitors plus supportive care, versus supportive care alone, for mild to moderate depression with somatic symptoms in primary care
Type: Journal Article

Abstract: OBJECTIVES: To determine (1) the effectiveness and cost-effectiveness of selective serotonin reuptake inhibitor (SSRI) treatment plus supportive care, versus supportive care alone, for mild to moderate depression in patients with somatic symptoms in primary care; and (2) the impact of the initial severity of depression on effectiveness and relative costs. To investigate the impact of demographic and social variables. DESIGN: The study was a parallel group, open-label, pragmatic randomised controlled trial. SETTING: The study took place in a UK primary care setting. Patients were referred by 177 GPs from 115 practices around three academic centres. PARTICIPANTS: Patients diagnosed with new episodes of depression and potentially in need of treatment. In total, 602 patients were referred to the study team, of whom 220 were randomised. INTERVENTIONS: GPs were asked to provide supportive care to all participants in follow-up consultations 2, 4, 8 and 12 weeks after the baseline assessment, to prescribe an SSRI of their choice to patients in the SSRI plus supportive care arm and to continue treatment for at least 4 months after recovery. They could switch antidepressants during treatment if necessary. They were asked to refrain from prescribing an antidepressant to those in the supportive care alone arm during the first 12 weeks but could prescribe to these patients if treatment became necessary. MAIN OUTCOME MEASURES: The primary outcome measure was Hamilton Depression Rating Scale (HDRS) score at 12-week follow-up. Secondary outcome measures were scores on HDRS at 26-week follow-up, Beck Depression Inventory, Medical Outcomes Study Short Form-36 (SF-36), Medical Interview Satisfaction Scale (MISS), modified Client Service Receipt Inventory and medical record data. RESULTS: SSRIs were received by 87% of patients in the SSRI plus supportive care arm and 20% in the supportive care alone arm. Longitudinal analyses demonstrated statistically significant differences in favour of the SSRI plus supportive care arm in terms of lower HDRS scores and higher scores on the SF-36 and MISS. Significant mean differences in HDRS score adjusted for baseline were found at both follow-up points when analysed separately but were relatively small. The numbers needed to treat for remission (to HDRS > 8) were 6 [95% confidence interval (CI) 4 to 26)] at 12 weeks and 6 (95% CI 3 to 31) at 26 weeks, and for significant improvement (HDRS reduction > or = 50%) were 7 (95% CI 4 to 83) and 5 (95% CI 3 to 13) respectively. Incremental cost-effectiveness ratios and cost-effectiveness planes suggested that adding an SSRI to supportive care was probably cost-effective. The cost-effectiveness acceptability curve for utility suggested that adding an SSRI to supportive care was cost-effective at the values of 20,000 pounds-30,000 pounds per quality-adjusted life-year. A poorer outcome on the HDRS was significantly related to greater severity at baseline, a higher physical symptom score and being unemployed. CONCLUSIONS: Treatment with an SSRI plus supportive care is more effective than supportive care alone for patients with mild to moderate depression, at least for those with symptoms persisting for 8 weeks and an HRDS score of > or = 12. The additional benefit is relatively small, and may be at least in part a placebo effect, but is probably cost-effective at the level used by the National Institute for Health and Clinical Excellence to make judgements about recommending treatments within the National Health Service. However, further research is required.

Randomised trial of monitoring, feedback, and management of care by telephone to improve treatment of depression in primary care
Type: Journal Article
Authors: G. E. Simon, M. Von Korff, C. Rutter, E. Wagner
Year: 2000
Publication Place: ENGLAND
Abstract: OBJECTIVE: To test the effectiveness of two programmes to improve the treatment of acute depression in primary care. DESIGN: Randomised trial. SETTING: Primary care clinics in Seattle. PATIENTS: 613 patients starting antidepressant treatment. INTERVENTION: Patients were randomly assigned to continued usual care or one of two interventions: feedback only and feedback plus care management. Feedback only comprised feedback and algorithm based recommendations to doctors on the basis of data from computerised records of pharmacy and visits. Feedback plus care management included systematic follow up by telephone, sophisticated treatment recommendations, and practice support by a care manager. MAIN OUTCOME MEASURES: Blinded interviews by telephone 3 and 6 months after the initial prescription included a 20 item depression scale from the Hopkins symptom checklist and the structured clinical interview for the current DSM-IV depression module. Visits, antidepressant prescriptions, and overall use of health care were assessed from computerised records. RESULTS: Compared with usual care, feedback only had no significant effect on treatment received or patient outcomes. Patients receiving feedback plus care management had a higher probability of both receiving at least moderate doses of antidepressants (odds ratio 1.99, 95% confidence interval 1.23 to 3.22) and a 50% improvement in depression scores on the symptom checklist (2.22, 1.31 to 3.75), lower mean depression scores on the symptom checklist at follow up, and a lower probability of major depression at follow up (0.46, 0.24 to 0.86). The incremental cost of feedback plus care management was about $80 ( pound50) per patient. CONCLUSIONS: Monitoring and feedback to doctors yielded no significant benefits for patients in primary care starting antidepressant treatment. A programme of systematic follow up and care management by telephone, however, significantly improved outcomes at modest cost.

Year: 2008
Abstract: Abstract. PURPOSE: To determine the effectiveness of the Alleviating Depression Among Patients With Cancer (ADAPt-C) collaborative care management for major depression or dysthymia. PATIENTS AND METHODS: Study patients included 472 low-income, predominantly female Hispanic patients with cancer age >or= 18 years with major depression (49%), dysthymia (5%), or both (46%). Patients were randomly assigned to intervention (n = 242) or enhanced usual care (EUC; n = 230). Intervention patients had access for up to 12 months to a depression clinical specialist (supervised by a psychiatrist) who offered education, structured psychotherapy, and maintenance/relapse prevention support. The psychiatrist prescribed antidepressant medications for patients preferring or assessed to require medication. RESULTS: At 12 months, 63% of intervention patients had a 50% or greater reduction in depressive symptoms from baseline as assessed by the Patient Health Questionnaire-9 (PHQ-9) depression scale compared with 50% of EUC patients (odds ratio [OR] = 1.98; 95% CI, 1.16 to 3.38; P = .01). Improvement was also found for 5-point decrease in PHQ-9 score among 72.2% of intervention patients compared with 59.7% of EUC patients (OR = 1.99; 95% CI, 1.14 to 3.50; P = .02). Intervention patients also experienced greater rates of depression treatment (72.3% v 10.4% of EUC patients; P < .0001) and significantly better quality-of-life outcomes, including social/family (adjusted mean difference between groups, 2.7; 95% CI, 1.22 to 4.17; P < .001), emotional (adjusted mean difference, 1.29; 95% CI, 0.26 to 2.22; P = .01), functional (adjusted mean difference, 1.34; 95% CI, 0.08 to 2.59; P = .04), and physical well-being (adjusted mean difference, 2.79; 95% CI, 0.49 to 5.1; P = .02). CONCLUSION: ADAPt-C collaborative care is feasible and results in significant reduction in depressive symptoms, improvement in quality of life, and lower pain levels compared with EUC for patients with depressive disorders in a low-income, predominantly Hispanic population in public sector oncology clinics.

Randomized trial of a telephone care management program for outpatients starting antidepressant treatment
Type: Journal Article
Authors: G. E. Simon, E. J. Ludman, B. H. Operskalski
Year: 2006
Publication Place: United States
Abstract: OBJECTIVE: This study evaluated the effectiveness of a structured telephone-based care management program for patients in a prepaid health plan receiving new antidepressant prescriptions from psychiatrists. METHODS: Potential participants were identified with computerized medical records and contacted by telephone. Eligible and consenting participants were randomly assigned to continued usual care (N=104) or to a three-session telephone care management program (N=103). Care management contacts included assessment of depressive symptoms, medication adherence, and medication side effects with structured feedback to treating psychiatrists. Effectiveness was assessed three and six months after randomization by blinded telephone assessments (depression scale on the Hopkins Symptom Checklist [SCL] and patient-rated global improvement). Computerized records were used to assess medication adherence and frequency of in-person follow-up visits. RESULTS: Compared with usual care, the care management intervention had no significant effect on the mean score of the SCL depression scale at six months, on the probability of 50 percent improvement in depressive symptoms (41 percent for care management and 37 percent for usual care), or on the probability of patient-rated improvement (57 percent for care management and 52 percent for usual care). Patients assigned to care management made significantly more medication management visits over six months (2.4 visits compared with 2.0 visits; p=.035), but there were no significant differences in rates of adequate medication treatment. CONCLUSIONS: This study found that a low-intensity telephone care management program did not appear to significantly improve clinical outcomes for patients starting antidepressant treatment. Compared with findings from earlier primary care studies, this study found that patients receiving care from a psychiatrist received more intensive treatment, although many still experienced poor outcomes.

Abstract: OBJECTIVE: Behavioral health homes provide primary care health services to patients with serious mental illness treated in community mental health settings. The objective of this study was to compare quality and outcomes of care between an integrated behavioral health home and usual care. METHOD: The study was a randomized trial of a behavioral health home developed as a partnership between a community mental health center and a Federally Qualified Health Center. A total of 447 patients with a serious mental illness and one or more cardiometabolic risk factors were randomly assigned to either the behavioral health home or usual care for 12 months. Participants in the behavioral health home received integrated medical care on-site from a nurse practitioner and a full-time nurse care manager subcontracted through the health center. RESULTS: Compared with usual care, the behavioral health home was associated with significant improvements in quality of cardiometabolic care, concordance of treatment with the chronic care model, and use of preventive services. For most cardiometabolic and general medical outcomes, both groups demonstrated improvement, although there were no statistically significant differences between the two groups over time. CONCLUSIONS: The results suggest that it is possible, even under challenging real-world conditions, to improve quality of care for patients with serious mental illness and cardiovascular risk factors. Improving quality of medical care may be necessary, but not sufficient, to improve the full range of medical outcomes in this vulnerable population.

Randomized trial of depression follow-up care by online messaging
Type: Journal Article
Authors: G. E. Simon, J. D. Ralston, J. Savarino, C. Pabiniak, C. Wentzel, B. H. Operskalski
Year: 2011
Publication Place: United States
Abstract: BACKGROUND: Quality of antidepressant treatment remains disturbingly poor. Rates of medication adherence and follow-up contact are especially low in primary care, where most depression treatment begins. Telephone care management programs can address these gaps, but reliance on live contact makes such programs less available, less timely, and more expensive. OBJECTIVE: Evaluate the feasibility, acceptability, and effectiveness of a depression care management program delivered by online messaging through an electronic medical record. DESIGN: Randomized controlled trial comparing usual primary care treatment to primary care supported by online care management SETTING: Nine primary care clinics of an integrated health system in Washington state PARTICIPANTS: Two hundred and eight patients starting antidepressant treatment for depression. INTERVENTION: Three online care management contacts with a trained psychiatric nurse. Each contact included a structured assessment (severity of depression, medication adherence, side effects), algorithm-based feedback to the patient and treating physician, and as-needed facilitation of follow-up care. All communication occurred through secure, asynchronous messages within an electronic medical record. MAIN MEASURES: An online survey approximately five months after randomization assessed the primary outcome (depression severity according to the Symptom Checklist scale) and satisfaction with care, a secondary outcome. Additional secondary outcomes (antidepressant adherence and use of health services) were assessed using computerized medical records. KEY RESULTS: Patients offered the program had higher rates of antidepressant adherence (81% continued treatment more than 3 months vs. 61%, p = 0.001), lower Symptom Checklist depression scores after 5 months (0.95 vs. 1.17, p = 0.043), and greater satisfaction with depression treatment (53% "very satisfied" vs. 33%, p = 0.004). LIMITATIONS: The trial was conducted in one integrated health care system with a single care management nurse. Results apply only to patients using online messaging. CONCLUSIONS: Our findings suggest that organized follow-up care for depression can be delivered effectively and efficiently through online messaging.

Randomized Trial of Reverse Colocated Integrated Care on Persons with Severe, Persistent Mental Illness in Southern Texas
Type: Journal Article
Authors: K. S. Errichetti, A. Flynn, E. Gaitan, M. M. Ramirez, M. Baker, Z. Xuan

Abstract: BACKGROUND: Persons with severe, persistent mental illness (SPMI) are at high risk for poor health and premature mortality. Integrating primary care in a mental health center may improve health outcomes in a population with SPMI in a socioeconomically distressed region of the USA. OBJECTIVE: To examine the effects of reverse colocated integrated care on persons with SPMI and co-morbid chronic disease receiving behavioral health services at a local mental health authority located at the US-Mexico border. DESIGN: Randomized trial evaluating the effect of a reverse colocated integrated care intervention among chronically ill adults. PARTICIPANTS: Participants were recruited at a clinic between November 24, 2015, and June 30, 2016. INTERVENTIONS: Receipt of at least two visits with a primary care provider and at least one visit with a chronic care nurse or dietician, compared with usual care (behavioral health only). MAIN MEASURES: The primary outcome was blood pressure. Secondary outcomes included HbA1c, BMI, total cholesterol, and depressive symptoms. Sociodemographic data were collected at baseline, and outcomes were measured at baseline and 6- and 12-month follow-ups. KEY RESULTS: A total of 416 participants were randomized to the intervention (n = 249) or usual care (n = 167). Groups were well balanced on almost all baseline characteristics. At 12 months, intent-to-treat analysis showed intervention participants improved their systolic blood pressure (β = - 3.86, p = 0.04) and HbA1c (β = - 0.36, p = 0.001) compared with usual care participants when controlling for age, sex, and other baseline characteristics. No participants withdrew from the study due to adverse effects. Per-protocol analyses yielded similar results to intent-to-treat analyses and found a significantly protective effect on diastolic blood pressure. Older and diabetic populations differentially benefited from this intervention. CONCLUSIONS: Colocation and integration of behavioral health and primary care improved blood pressure and HbA1c after 1-year follow-up for persons with SPMI and co-morbid chronic disease in a US-Mexico border community.

Abstract:

IMPORTANCE: New approaches are needed to provide care for individuals with problematic opioid use (POU). Rapid access addiction medicine (RAAM) clinics offer a flexible, low-barrier, rapid access care model for this population. OBJECTIVE: To assess the associations of RAAM clinics with emergency department (ED) visits, hospitalizations, and mortality for people with POU. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study involving a matched control group was performed using health administrative data from Ontario, Canada. Anonymized data from 4 Ontario RAAM clinics (cities of Ottawa, Toronto, Oshawa, and Sudbury) were linked with health administrative data. Analyses were performed on a cohort of individuals who received care at participating RAAM clinics and geographically matched controls who did not receive care at a RAAM clinic. All visits occurred between October 2, 2017, and October 30, 2019, and data analyses were completed in spring 2023. A propensity score-matching approach was used to balance confounding factors between groups, with adjustment for covariates that remained imbalanced after matching. EXPOSURES: Individuals who initiated care through the RAAM model (including assessment, pharmacotherapy, brief counseling, harm reduction, triage to appropriate level of care, navigation to community services and primary care, and related care) were compared with individuals who did not receive care through the RAAM model. MAIN OUTCOMES AND MEASURES: The primary outcome was a composite measure of ED visits for any reason, hospitalization for any reason, and all-cause mortality (all measured up to 30 days after index date). Outcomes up to 90 days after index date, as well as outcomes looking at opioid-related ED visits and hospitalizations, were also assessed. RESULTS: In analyses of the sample of 876 patients formed using propensity score matching, 440 in the RAAM group (mean [SD] age, 36.5 [12.6] years; 276 [62.7%] male) and 436 in the control group (mean [SD] age, 36.8 [13.8] years; 258 [59.2%] male), the pooled odds ratio (OR) for the primary, 30-day composite outcome of all-cause ED visit, hospitalization, or mortality favored the RAAM model (OR, 0.68; 95% CI, 0.50-0.92). Analysis of the same outcome for opioid-related reasons only also favored the RAAM intervention (OR, 0.47; 95% CI, 0.29-0.76). Findings for the individual events of hospitalization, ED visit, and mortality at both 30-day and 90-day follow-up also favored the RAAM model, with comparisons reaching statistical significance in most cases. CONCLUSIONS AND RELEVANCE: In this cohort study of individuals with POU, RAAM clinics were associated with reductions in ED visits, hospitalizations, and mortality. These findings provide valuable evidence toward a broadened adoption of the RAAM model in other regions of North America and beyond.
