Trajectory classes of depression in a randomized depression trial of heart failure patients: a reanalysis of the SADHART-CHF trial.

ABSTRACT: The objective of this article was to determine whether, in drug intervention trials, growth mixture modeling (GMM) is able to identify drug-responsive trajectory classes that are not evident in traditional growth modeling approaches.We reanalyzed acute phase (biweekly data up to 7 occasions) and longitudinal (12 months) data on the 469 patients in the SADHART-CHF study of the safety and efficacy of sertraline for depression in patients with heart failure. GMM was used to identify the trajectory classes present in the treatment and placebo groups, based on Hamilton Depression Rating Scale scores.Two distinct trajectory classes were identified in the treatment group: (1) chronic depressives (12%), who remained depressed through the treatment phase; and (2) responders (88%), who had scores indicating nondepression at the conclusion of the acute phase. At baseline, chronic depressives were distinguished by higher Hamilton Depression Rating Scale scores, the presence of implantable cardioverter defibrillators, and a history of anxiety. During follow-up, they were more likely to have unstable angina. Only responders remitted (70%). Three distinct trajectories were identified in the placebo group: (1) moderating depressives (19%), (2) temporary improvers (13%), and (3) responders (68%). At baseline, the classes differed in mean Hamilton Depression Rating Scale scores, responders' scores falling between the other 2 classes, and the proportion with renal disease. Only remission differed at follow-up: responders (76%), moderating depressives (21%), and temporary improvers (3%). Where the traditional analytic approach found improvement from moderate to mild depression but no significant treatment effect, GMM found response in 20% more people in the treatment group than in the placebo group.Unlike conventionally used, standard analytic approaches, which focus on intervention impact at study end or change from baseline to study end, GMM enables maximum use of repeated data to identify unique trajectories of latent classes that are responsive to the intervention.

Project description:The objective was to test the hypothesis that heart failure (HF) patients treated with sertraline will have lower depression scores and fewer cardiovascular events compared with placebo.Depression is common among HF patients. It is associated with increased hospitalization and mortality.The SADHART-CHF (Sertraline Against Depression and Heart Disease in Chronic Heart Failure) trial was a randomized, double-blind, placebo-controlled trial of sertraline 50 to 200 mg/day versus matching placebo for 12 weeks. All participants also received nurse-facilitated support. Eligible patients were age 45 years or older with HF (left ventricular ejection fraction < or =45%, New York Heart Association functional class II to IV) and clinical depression (Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition criteria for current major depressive disorder). Those with significant cognitive impairment, psychosis, recent alcohol or drug dependence, bipolar or severe personality disorder, active suicidal ideation, and current antipsychotic or antidepressant medications were excluded. Primary end points were change in depression severity (Hamilton Depression Rating Scale total score) and composite cardiovascular status at 12 weeks.A total of 469 patients were randomized (n = 234 sertraline, n = 235 placebo). The mean +/- SE change from baseline to 12 weeks in the Hamilton Depression Rating Scale total score was -7.1 +/- 0.5 (sertraline) and -6.8 +/- 0.5 (placebo) (p < 0.001 from baseline, p = 0.89 between groups, mean change between groups -0.4; 95% confidence interval: -1.7 to 0.92). The proportions whose composite cardiovascular score worsened, improved, or was unchanged were 29.9%, 40.6%, and 29.5%, respectively, in the sertraline group and 31.1%, 43.8%, and 25.1%, respectively, in the placebo group (p = 0.78).Sertraline was safe in patients with significant HF. However, treatment with sertraline compared with placebo did not provide greater reduction in depression or improved cardiovascular status among patients with HF and depression.

Project description:AimsPatients with heart failure (HF) have impaired quality of life (QoL). The randomized controlled trial PHARM-CHF investigated whether an interdisciplinary intervention consisting of regular contacts with the community pharmacy and weekly dosing aids improves medication adherence in patients with HF. It is unknown how an intervention involving frequent structured pharmacy visits affects QoL. Our aim was to explore adherence to the intervention and effects on QoL.Methods and resultsAmong 237 patients, n = 110 were randomized to pharmacy care and n = 127 to usual care. The pharmacy care group received a medication review followed by (bi-)weekly dose dispensing and counselling. The median follow-up was 2.0 years [inter-quartile range (IQR) 1.2-2.7]. Median interval between pharmacy visits was 8.4 days (IQR 8.0-10.3) and the visits lasted in median 14 min (IQR 10-15). Median adherence to the intervention was 96% (IQR 84-100). QoL at 365 days was predefined as a main secondary and at 730 days as another secondary endpoint in PHARM-CHF. QoL was measured by the Minnesota Living with Heart Failure Questionnaire; and for 111 patients (n = 47 in the pharmacy care group and n = 64 in the usual care group), data were available at baseline, and after 365 and 730 days (mean age 74 years; 41% female). Improvement in QoL was numerically higher in the pharmacy care group after 365 days and was significantly better after 730 days (difference in total scores -7.7 points [-14.5 to -1.0]; P = 0.026) compared to the usual care group. In all subgroups examined, this treatment effect was preserved. Improvements in the physical and emotional dimensions were numerically higher in the pharmacy care group after 365 days and were significantly better after 730 days: -4.0 points [-6.9 to -1.2]; P = 0.006, and -1.9 points [-3.7 to -0.1]; P = 0.039, respectively.ConclusionsA pharmacy-based interdisciplinary intervention was well received by the patients and suggests clinically important improvements in QoL.

Project description:ImportanceNational guidelines recommend early palliative care for patients with advanced heart failure, which disproportionately affects rural and minority populations.ObjectiveTo determine the effect of an early palliative care telehealth intervention over 16 weeks on the quality of life, mood, global health, pain, and resource use of patients with advanced heart failure.Design, setting, and participantsA single-blind, intervention vs usual care randomized clinical trial was conducted from October 1, 2015, to May 31, 2019, among 415 patients 50 years or older with New York Heart Association class III or IV heart failure or American College of Cardiology stage C or D heart failure at a large Southeastern US academic tertiary medical center and a Veterans Affairs medical center serving high proportions of rural dwellers and African American individuals.InterventionsThe ENABLE CHF-PC (Educate, Nurture, Advise, Before Life Ends Comprehensive Heartcare for Patients and Caregivers) intervention comprises an in-person palliative care consultation and 6 weekly nurse-coach telephonic sessions (20-40 minutes) and monthly follow-up for 48 weeks.Main outcomes and measuresPrimary outcomes were quality of life (as measured by the Kansas City Cardiomyopathy Questionnaire [KCCQ]: score range, 0-100; higher scores indicate better perceived health status and clinical summary scores ≥50 are considered "fairly good" quality of life; and the Functional Assessment of Chronic Illness Therapy-Palliative-14 [FACIT-Pal-14]: score range, 0-56; higher scores indicate better quality of life) and mood (as measured by the Hospital Anxiety and Depression Scale [HADS]) over 16 weeks. Secondary outcomes were global health (Patient Reported Outcome Measurement System Global Health), pain (Patient Reported Outcome Measurement System Pain Intensity and Interference), and resource use (hospital days and emergency department visits).ResultsOf 415 participants (221 men; baseline mean [SD] age, 63.8 [8.5] years) randomized to ENABLE CHF-PC (n = 208) or usual care (n = 207), 226 (54.5%) were African American, 108 (26.0%) lived in a rural area, and 190 (45.8%) had a high-school education or less, and a mean (SD) baseline KCCQ score of 52.6 (21.0). At week 16, the mean (SE) KCCQ score improved 3.9 (1.3) points in the intervention group vs 2.3 (1.2) in the usual care group (difference, 1.6; SE, 1.7; d = 0.07 [95% CI, -0.09 to 0.24]) and the mean (SE) FACIT-Pal-14 score improved 1.4 (0.6) points in the intervention group vs 0.2 (0.5) points in the usual care group (difference, 1.2; SE, 0.8; d = 0.12 [95% CI, -0.03 to 0.28]). There were no relevant between-group differences in mood (HADS-anxiety, d = -0.02 [95% CI, -0.20 to 0.16]; HADS-depression, d = -0.09 [95% CI, -0.24 to 0.06]).Conclusions and relevanceThis randomized clinical trial with a majority African American sample and baseline good quality of life did not demonstrate improved quality of life or mood with a 16-week early palliative care telehealth intervention. However, pain intensity and interference (secondary outcomes) demonstrated a clinically important improvement.Trial registrationClinicalTrials.gov Identifier: NCT02505425.

Project description:ImportanceDepression and inadequate self-care are common and interrelated problems that increase the risks of hospitalization and mortality in patients with heart failure (HF).ObjectiveTo determine the efficacy of an integrative cognitive behavior therapy (CBT) intervention for depression and HF self-care.Design, setting, and participantsRandomized clinical trial with single-blind outcome assessments. Eligible patients were enrolled at Washington University Medical Center in St Louis between January 4, 2010, and June 28, 2013. The primary data analyses were conducted in February 2015. The participants were 158 outpatients in New York Heart Association Class I, II, and III heart failure with comorbid major depression.InterventionsCognitive behavior therapy delivered by experienced therapists plus usual care (UC), or UC alone. Usual care was enhanced in both groups with a structured HF education program delivered by a cardiac nurse.Main outcomes and measuresThe primary outcome was severity of depression at 6 months as measured by the Beck Depression Inventory. The Self-Care of Heart Failure Index Confidence and Maintenance subscales were coprimary outcomes. Secondary outcomes included measures of anxiety, depression, physical functioning, fatigue, social roles and activities, and quality of life. Hospitalizations and deaths were exploratory outcomes.ResultsOne hundred fifty-eight patients were randomized to UC (n = 79) or CBT (n = 79). Within each arm, 26 (33%) of the patients were taking an antidepressant at baseline. One hundred thirty-two (84%) of the participants completed the 6-month posttreatment assessments; 60 (76%) of the UC and 58 (73%) of the CBT participants completed every follow-up assessment (P = .88). Six-month depression scores were lower in the CBT than the UC arm on the Beck Depression Inventory (BDI-II) (12.8 [10.6] vs 17.3 [10.7]; P = .008). Remission rates differed on the BDI-II (46% vs 19%; number needed to treat [NNT] = 3.76; 95% CI, 3.62-3.90; P < .001) and the Hamilton Depression Scale (51% vs 20%; NNT = 3.29; 95% CI, 3.15-3.43; P < .001). The groups did not differ on the Self-Care Maintenance or Confidence subscales. The mean (SD) Beck Depression Inventory scores 6 months after randomization were lower in the CBT (12.8 [10.6]) than the UC arm (17.3 [10.7]), P = .008. There were no statistically significant differences between the groups on the Self-Care Maintenance or Confidence subscale scores or on physical functioning measures. Anxiety and fatigue scores were lower and mental- and HF-related quality of life and social functioning scores were higher at 6 months in the CBT than the UC arm, and there were fewer hospitalizations in the intervention than the UC arm.Conclusions and relevanceA CBT intervention that targets both depression and heart failure self-care is effective for depression but not for HF self-care or physical functioning relative to enhanced UC. Additional benefits include reduced anxiety and fatigue, improved social functioning, and better health-related quality of life.Trial registrationclinicaltrials.gov Identifier: NCT01028625.

Project description:ImportanceDepression is often comorbid in patients with heart failure (HF) and is associated with worse clinical outcomes. However, depression generally goes unrecognized and untreated in this population.ObjectiveTo determine whether a blended collaborative care program for treating both HF and depression can improve clinical outcomes more than collaborative care for HF only and physicians' usual care (UC).Design, setting, and participantsThis 3-arm, single-blind, randomized effectiveness trial recruited 756 participants with HF with reduced left ventricular ejection fraction (<45%) from 8 university-based and community hospitals in southwestern Pennsylvania between March 2014 and October 2017 and observed them until November 2018. Participants included 629 who screened positive for depression during hospitalization and 2 weeks postdischarge and 127 randomly sampled participants without depression to facilitate further comparisons. Key analyses were performed November 2018 to March 2019.InterventionsSeparate physician-supervised nurse teams provided either 12 months of collaborative care for HF and depression ("blended" care) or collaborative care for HF only (enhanced UC [eUC]).Main outcomes and measuresThe primary outcome was mental health-related quality of life (mHRQOL) as measured by the Mental Component Summary of the 12-item Short Form Health Survey (MCS-12). Secondary outcomes included mood, physical function, HF pharmacotherapy use, rehospitalizations, and mortality.ResultsOf the 756 participants (mean [SD] age, 64.0 [13.0] years; 425 [56%] male), those with depression reported worse mHRQOL, mood, and physical function but were otherwise similar to those without depression (eg, mean left ventricular ejection fraction, 28%). At 12 months, blended care participants reported a 4.47-point improvement on the MCS-12 vs UC (95% CI, 1.65 to 7.28; P = .002), but similar scores as the eUC arm (1.12; 95% CI, -1.15 to 3.40; P = .33). Blended care participants also reported better mood than UC participants (Patient-Reported Outcomes Measurement Information System-Depression effect size, 0.47; 95% CI, 0.28 to 0.67) and eUC participants (0.24; 95% CI, 0.07 to 0.41), but physical function, HF pharmacotherapy use, rehospitalizations, and mortality were similar by both baseline depression and randomization status.Conclusions and relevanceIn this randomized clinical trial of patients with HF and depression, telephone-delivered blended collaborative care produced modest improvements in mHRQOL, the primary outcome, on the MCS-12 vs UC but not eUC. Although blended care did not differentially affect rehospitalization and mortality, it improved mood better than eUC and UC and thus may enable organized health care systems to provide effective first-line depression care to medically complex patients.Trial registrationClinicalTrials.gov Identifier: NCT02044211.
