RESUMO

PURPOSE: Education and feedback on hypertension management has been associated with improved hypertension control. This study aimed to assess the effectiveness of such interventions to reduce the risk of stroke and cardiovascular events. MATERIALS AND METHODS: Individuals ≥18 years with a blood pressure (BP) recording in Västerbotten or Södermanland County during the study period 2001 to 2009 were included in 108 serial cohort studies, each with 24 months follow-up. The primary outcome was risk of first-ever stroke in Västerbotten County (intervention) compared with Södermanland County (control). Secondary outcomes were first-ever major adverse cardiovascular event (MACE), myocardial infarction, and heart failure, as well as all-cause and cardiovascular mortality. All outcomes were analysed using time-to-event data included in a Cox proportional hazards model adjusted for age, sex, hypertension, diabetes, coronary artery disease, atrial fibrillation, systolic BP at inclusion, marital status, and disposable income. RESULTS: A total of 121 365 individuals (mean [SD] age at inclusion 61.7 [16.3] years; 59.9% female; mean inclusion BP 142.3/82.6 mmHg) in the intervention county were compared to 131 924 individuals (63.6 [16.2] years; 61.2% female; 144.1/81.1 mmHg) in the control county. A first-ever stroke occurred in 2 823 (2.3%) individuals in the intervention county, and 3 584 (2.7%) individuals in the control county (adjusted hazard ratio 0.96, 95% CI 0.90 to 1.03). No differences were observed for MACE, myocardial infarction or heart failure, whereas all-cause mortality (HR 0.91, 95% CI 0.87 to 0.95) and cardiovascular mortality (HR 0.91, 95% CI 0.85 to 0.98) were lower in the intervention county. CONCLUSIONS: This study does not support an association between education and feedback on hypertension management to primary care physicians and the risk for stroke or cardiovascular outcomes. The observed differences for mortality outcomes should be interpreted with caution.

RESUMO

INTRODUCTION: The Attempted Suicide Short Intervention Program (ASSIP) is a brief psychotherapeutic intervention, and a pivotal study found it to be remarkably effective in reducing repeat suicide attempts. OBJECTIVE: To compare the effectiveness of ASSIP to crisis counseling (CC) in a randomized clinical trial (ISRCTN13464512). METHODS: Adult patients receiving treatment for a suicide attempt in a Helsinki City general hospital emergency room in 2016-2017 were eligible to participate. We excluded psychotic or likely non-adherent substance-abusing or substance-dependent patients. Eligible patients (n = 239) were randomly allocated to one of two interventions. (a) ASSIP comprised three visits, including a videotaped first visit, a case formulation, and an individualized safety plan, plus letters from the therapist every 3 months for 1 year, and then, every 6 months for the next year. (b) CC typically involved 2-5 (median 3) face-to-face individual sessions. In addition, all participants received their usual treatment. One and 2 years after baseline, information related to participants' suicidal thoughts and attempts, and psychiatric treatment received was collected via telephone and from medical and psychiatric records. RESULTS: Among randomized patients, two-thirds initiated either ASSIP (n = 89) or CC (n = 72), with 73 (82%) completing ASSIP and 58 (81%) CC. The proportion of patients who attempted suicide during the 2-year follow-up did not differ significantly between ASSIP and CC (29.2% [26/89] vs. 35.2% [25/71], OR 0.755 [95% Cl 0.379-1.504]). CONCLUSIONS: We found no difference in the effectiveness of the two brief interventions to prevent repeat suicide attempts.

RESUMO

Background and Aim: In psychiatric clinical practice, comorbidity of depression and alcohol use disorder (AUD) is common. Both disorders have a negative impact on health-related quality of life (HRQoL) in general population. However, research on the impact of comorbid AUD on HRQoL among clinically depressed patients is limited. The purpose of this study was to explore the impact of a psychosocial treatment intervention on HRQoL for depressive patients in specialized psychiatric care with a special focus on the impact of AUD on HRQoL. Material and Methods: Subjects were 242 patients of the Ostrobothnia Depression Study (ClinicalTrials.gov Identifier NCT02520271). Patients referred to specialized psychiatric care who scored at least 17 points on the Beck Depression Inventory at baseline and who had no psychotic disorders were included in the ODS. The treatment intervention in ODS comprised behavioral activation for all but began with motivational interviewing for those with AUD. HRQoL was assessed regularly during 24-month follow-up by the 15D instrument. In the present study, HRQoL of ODS patients with or without AUD was compared and the factors explaining 15D score analyzed with a linear mixed model. In order to specify the impact of clinical depression on HRQoL during the early phase of treatment intervention, a general population sample of the Finnish Health 2011 Survey was used as an additional reference group. Results: HRQoL improved among all ODS study sample patients regardless of comorbid AUD during the first year of follow-up. During 12-24 months of follow-up the difference between groups was seen as HRQoL continued to improve only among the non-AUD patients. A combination of male gender, anxiety disorder, and AUD was associated with the poorest HRQoL in this sample. In combined sample analyses with the reference group, clinical depression had an impact on HRQoL in short-term follow-up regardless of the treatment intervention. Conclusions: This study suggests that, in terms of improvement in HRQoL, the heterogenous group of depressive patients in specialized psychiatric care can be successfully treated with behavioral activation in combination with motivational interviewing for those with AUD.

RESUMO

BACKGROUND: The Ostrobothnia Depression Programme (ODP) in Finland was intended to implement two evidence-based brief psychotherapy interventions, namely motivational interview and behavioural activation, in several regional psychiatric teams. A simultaneous effectiveness study was conducted. Considerable tension was encountered between these two arms, causing resistance to change. We conducted a qualitative case study to better understand this tension and to discuss how managerial and executive practices may ensure the successful running of a hybrid design programme. METHODS: We conducted focus group interviews to evaluate the phases of preparation and practical execution of the ODP from the perspectives of management and the programme executives. To gather the data, we applied the revised Socratic approach for health technology assessment and focus group interviews. We analysed the data deductively according to the Normalization Process Theory. RESULTS: We identified two main critical issues: (1) The ODP programme plan ignored the team leaders' crucial role in influencing the implementation climate and mobilizing organizational strategies. The ODP had a simplistic top-down design with minimal and delayed collaboration with its target groups in the preparation phase. (2) Incongruence occurred between what the project group had explicitly communicated about being the spearhead of the ODP and what they then actually enacted. These two issues caused tension between the implementation efforts and the effectiveness study as well as resistance to change among the staff. CONCLUSION: Early, open collaboration with all prospective stakeholders towards a shared understanding about the programme is the first action the programme administrators should take. Agreement on goals and the means to achieve them would lower tension between the two arms of a hybrid design programme, thereby reducing resistance to change. Congruence between the goals communicated and the actual managerial and executive actions is of paramount importance in getting the programme recipients on board.

RESUMO

Importance: Elevated systolic blood pressure (SBP) is the most important risk factor for premature death worldwide. However, hypertension detection and control rates continue to be suboptimal. Objective: To assess the association of education and feedback to primary care physicians with population-level SBP and hypertension control rates. Design, Setting, and Participants: This pooled series of 108 population-based cohort studies involving 283 079 patients used data from primary care centers in 2 counties (Västerbotten and Södermanland) in Sweden from 2001 to 2009. Participants were individuals aged 18 years or older who had their blood pressure (BP) measured and recorded in either county during the intervention period. All analyses were performed in February 2019. Exposures: An intervention comprising education and feedback for primary care physicians in Västerbotten County (intervention group) compared with usual care in Södermanland County (control group). Main Outcomes and Measures: Difference in mean SBP levels between counties and likelihood of hypertension control in the intervention county compared with the control county during 24 months of follow-up. Results: A total of 136 541 unique individuals (mean [SD] age at inclusion, 64.6 [16.1] years; 57.0% female; mean inclusion BP, 142/82 mm Hg) in the intervention county were compared with 146 538 individuals (mean [SD] age at inclusion, 65.7 [15.9] years; 58.3% female; mean inclusion BP, 144/80 mm Hg) in the control county. Mean SBP difference between counties during follow-up, adjusted for inclusion BP and other covariates, was 1.1 mm Hg (95% CI, 1.0-1.1 mm Hg). Hypertension control improved by 8.4 percentage points, and control was achieved in 37.8% of participants in the intervention county compared with 29.4% in the control county (adjusted odds ratio, 1.30; 95% CI, 1.29-1.31). Differences between counties increased during the intervention period and were more pronounced in participants with higher SBP at inclusion. Results were consistent across all subgroups. Conclusions and Relevance: This study suggests that SBP levels and hypertension control rates in a county population may be improved by educational approaches directed at physicians and other health care workers. Similar strategies may be adopted to reinforce the implementation of clinical practice guidelines for hypertension management.

RESUMO

PURPOSE: Behavioural activation and motivational interviewing, both evidence-based treatments (EBTs), were implemented in secondary psychiatric care. This longitudinal evaluation of a real-world programme focused on the penetration of EBT adoption and its associations with therapist-related and perceived intervention-related variables. The implementation plan was also compared to sub-processes of Normalization Process Theory. MATERIAL AND METHODS: Six participating units employed 72 therapists regularly and they comprise the target group. Due to staff turnover, a total of 84 therapists were trained stepwise. Three survey points (q1, q2, q3) were set for a four-year cycle beginning a year after the initial training and completed 4-5 months after closing patient recruitment. The implementation plan included two workshop days, one for each EBT, and subsequent case consultation groups and other more general strategies. RESULTS: Fifty-seven (68%) of programme-trained therapists responded to one or more of three questionnaires. The self-reported penetration covers about a third of the target group a few months after the completion of the programme. Therapists' favourable perceptions of the EBTs regarding relative advantage, compatibility and complexity were associated with their sustained adoption. Therapists' background factors (e.g. work experience) and positive adoption intention at q1 did not predict the actual adoption of the EBTs at q3. No specific sustainment strategies were included in the implementation plan. CONCLUSION: Brief but multi-faceted training with subsequent case consultations promoted the adoption of EBTs in a real-world setting. Adding specific sustainment strategies to the implementation plan is proposed to ensure the long-term survival of the implementation outcomes.

RESUMO

BACKGROUND: More systematic use of evidence-based brief therapies is needed in the treatment of depression within psychiatric care. The aim of this study was to explore the impact of behavioral activation therapy (BA) for patients with depressive symptoms in a routine clinical setting of secondary psychiatric care. METHODS: The BA-treated intervention group (n = 242) comprised patients with depressive symptoms (Beck Depression Inventory (BDI) score ≥ 17 at baseline). The control group (n = 205) patients received treatment as usual in the same catchment area. The groups were matched at baseline using BDI and Alcohol Use Disorders Identification Test scores and inpatient/outpatient status. The groups were compared at 6-, 12- and 24-month follow-up points on functional outcome (Global Assessment of Functioning scale), service use, dropout and deaths. The Montgomery-Åsberg Depression Rating Scale was used to assess depressive symptoms in the intervention group. RESULTS: The estimated difference in GAF score between intervention and control group patients was significant at 12- and 24-months follow-up points in favor of intervention group (GAF score difference 4.85 points, p = 0.006 and 5.71 points, p = 0.005, respectively; estimate for patient group 2.26, p = 0.036). The rates of dropout, mortality and service use were similar between the groups. Among the intervention group patients, the estimated improvement in MADRS score compared to baseline was statistically significant throughout the follow-up (p < 0.001 at all follow-up points). CONCLUSIONS: The systematic use of BA among secondary psychiatric care depressive patients provides encouraging results despite the patients had various comorbid non-psychotic disorders.

RESUMO

BACKGROUND: Assessment of antihypertensive treatment is normally based on the mean value of a number of blood pressure (BP) measurements. However, it is uncertain whether high in-treatment visit-to-visit BP variability may be harmful in hypertensive patients with left ventricular hypertrophy (LVH). METHODS: In 8505 patients randomized to losartan vs. atenolol-based treatment in the LIFE study, we tested whether BP variability assessed as SD and range for BP6-24 months measured at 6, 12, 18 and 24 months of treatment was associated with target organ damage (TOD) defined by LVH on ECG and urine albumin/creatinine ratio at 24 months, and predicted the composite endpoint (CEP) of cardiovascular death, nonfatal myocardial infarction (MI) or stroke occurring after 24 months (CEP = 630 events). RESULTS: In multiple regression models adjusted for mean BP6-24 months and treatment allocation, neither high BP6-24 months SD nor wide range were related to TOD at 24 months, except for a weak association between Sokolow-Lyon voltage and DBP6-24 months SD and range (both ß = 0.04, P < 0.01). Independently of mean BP6-24 months, treatment allocation, TOD and baseline characteristics in Cox regression models, CEP after 24 months was associated with DBP6-24 months SD [hazard ratio per 1 mmHg increase1.04, 95% confidence interval (95% CI) 1.01-1.06, P = 0.005], range (hazard ratio 1.02, 95% CI 1.01-1.03, P = 0.004), SBP6-24 months SD (hazard ratio 1.01, 95% CI 0.99-1.02, P = 0.07) and range (hazard ratio 1.006, 95% CI 1.001-1.01, P = 0.04). Adjusted for the same factors, stroke was associated with DBP6-24 months SD (hazard ratio 1.06, 95% CI 1.02-1.10, P = 0.001), range (hazard ratio 1.03, 95% CI 1.01-1.04, P = 0.001), SBP6-24 months SD (hazard ratio 1.02, 95% CI 1.002-1.04, P = 0.04) and range (hazard ratio 1.008, 95% CI 1.001-1.02, P = 0.05), but MI was not. CONCLUSION: In LIFE patients, higher in-treatment BP6-24 months variability was independently of mean BP6-24 months associated with later CEP and stroke, but not with MI or TOD after 24 months.

RESUMO

This implementation study was part of the Ostrobothnia Depression Study, in Finland, which covered implementation of motivational interviewing (MI) and behavioral activation (BA) within regional public psychiatric secondary care. It aimed to evaluate the mid-term progress of implementation and related factors. Altogether, 80 therapists had been educated through the implementation program by the point of the mid-term evaluation. Eligible information for evaluation was gathered using two questionnaires (q1, q2) with a one-year interval. A total of 45 of the 80 therapists completed q1, 30 completed q2, and 24 completed both questionnaires. Professional education was the only background factor associated with adopting the interventions (q1: p=0.059, q2: p=0.023), with higher education indicating greater activity. On the basis of trends such as changes in overall usefulness score from q1 to q2, the most involved therapists were slightly more likely to adopt MI/BA. Our experience so far suggests that encouraging staff to begin using new interventions during education is very important. The Consolidated Framework for Implementation Research was found to be a useful tool for constructing the evaluation.

RESUMO

BACKGROUND: The Losartan Intervention For Endpoint reduction in hypertension (LIFE) study has previously demonstrated a beneficial effect of losartan compared to atenolol-based antihypertensive treatment in patients with essential hypertension and left-ventricular hypertrophy (LVH). However, patient age often influences the choice of antihypertensive drugs. Therefore, we investigated the influence of age on the effects of losartan versus atenolol-based antihypertensive treatment. METHODS: A total of 9193 hypertensive patients with LVH aged 45-83 years were followed for a mean of 4.8 years. Blood pressure, high-density lipoprotein cholesterol (HDL-C), Sokolow-Lyon voltage, Cornell voltage-duration product and urine albumin-creatinine ratio (UACR) were measured yearly throughout the study. Patients were divided into two age groups according to the median age of 67 years and the effects of losartan versus atenolol-based antihypertensive treatment on the primary composite endpoint (CEP) consisting of cardiovascular death, nonfatal stroke or nonfatal myocardial infarction were investigated. RESULTS: The beneficial effect of losartan versus atenolol-based treatment was greater in the group of patients older than 67 years [hazard ratio 0.79 (0.69-0.91), P = 0.001] compared to the group of patients younger than 67 years [hazard ratio 1.03 (0.82-1.28), P = 0809], P = 0.045 for interaction. The beneficial effects of losartan versus atenolol-based antihypertensive treatment on pulse pressure, HDL-C, UACR, and Cornell and Sokolow-Lyon voltage were not more pronounced in patients older than 67 years compared to patients younger than 67 years. All five risk factors considered as time-varying covariates predicted CEP independently (P < 0.01) with the exception of pulse pressure (P = 0.37) and the interaction between age and treatment on outcome remained significant (P = 0.042). CONCLUSIONS: We showed a greater beneficial effect of losartan versus atenolol-based antihypertensive treatment in the group of patients older than 67 years compared to the group of patients younger than 67 years. This difference was not explained by a more pronounced effect of losartan-based treatment on any of the cardiovascular risk factors demonstrated to have independent prognostic importance.

RESUMO

BACKGROUND: Low serum potassium (K) is associated with increased blood pressure, impaired cardiac function and renal dysfunction. Although lower serum K is associated with cardiac hypertrophy in animal models, the relationship of low serum K to the presence and severity of electrocardiographic left ventricular hypertrophy (LVH) is unclear. METHODS: Baseline and yearly Cornell product LVH levels were examined in relation to low serum K (serum K ≤ 3.90 mEq/l, the lowest quartile of baseline K levels) in 8586 patients with baseline K levels. Patients were randomized to losartan-vs atenolol-based treatment and additional hydrochlorothiazide (HCTZ) therapy as needed. RESULTS: After adjusting for age, sex, race, prior antihypertensive treatment, losartan vs atenolol therapy, HCTZ use, baseline diastolic and systolic pressure, body mass index, serum creatinine and urine albumin/creatinine ratio, baseline serum K ≤ 3.90 was associated with significantly higher mean baseline Cornell product LVH (2898 vs 2801 mm•ms, p = 0.001) and a 24% higher risk of Cornell product LVH > 2440 mm•ms at baseline (OR 1.24, 95% CI 1.11-1.38, p < 0.001). After also adjusting for baseline Cornell product and changes in diastolic and systolic pressure between baseline and each year of measurement, in-treatment serum K ≤ 3.90 determined yearly was associated with significantly higher mean Cornell product LVH at years 1-3 and with statistically significant 16-32% increased risks of LVH by Cornell product at years 1-4. CONCLUSIONS: A low serum K is independently associated with a greater likelihood and severity of Cornell product LVH during antihypertensive therapy.

RESUMO

OBJECTIVES: To determine the population distribution of cardiovascular risk in eight low- and middle-income countries and compare the cost of drug treatment based on cardiovascular risk (cardiovascular risk thresholds ≥ 30%/≥ 40%) with single risk factor cutoff levels. STUDY DESIGN AND SETTING: Using World Health Organization (WHO) and the International Society of Hypertension risk prediction charts, cardiovascular risk was categorized in a cross-sectional study of 8,625 randomly selected people aged 40-80 years (mean age, 54.6 years) from defined geographic regions of Nigeria, Iran, China, Pakistan, Georgia, Nepal, Cuba, and Sri Lanka. Cost estimates for drug therapy were calculated for three countries. RESULTS: A large fraction (90.0-98.9%) of the study population has a 10-year cardiovascular risk <20%. Only 0.2-4.8% are in the high-risk categories (≥ 30%). Adopting a total risk approach and WHO guidelines recommendations would restrict unnecessary drug treatment and reduce the drug costs significantly. CONCLUSION: Adopting a total cardiovascular risk approach instead of a single risk factor approach reduces health care expenditure by reducing drug costs. Therefore, limited resources can be more efficiently used to target high-risk people who will benefit the most. This strategy needs to be complemented with population-wide measures to shift the cardiovascular risk distribution of the whole population.

RESUMO

Patients with resistant hypertension are at increased risk for cardiovascular events. The addition of new treatments to existing therapies will help achieve blood pressure (BP) goals in more resistant hypertension patients. In the current trial, 849 patients with resistant hypertension receiving ≥3 antihypertensive drugs, including a diuretic, at optimized doses were randomized to the selective endothelin A receptor antagonist darusentan, placebo, or the central α-2 agonist guanfacine. The coprimary end points of the study were changes from baseline to week 14 in trough, sitting systolic BP, and diastolic BP measured in the clinic. Decreases from baseline to week 14 in systolic BP for darusentan (-15±14 mm Hg) were greater than for guanfacine (-12±13 mm Hg; P<0.05) but not greater than placebo (-14±14 mm Hg). Darusentan, however, reduced mean 24-hour systolic BP (-9±12 mm Hg) more than placebo (-2±12 mm Hg) or guanfacine (-4±12 mm Hg) after 14 weeks of treatment (P<0.001 for each comparison). The most frequent adverse event associated with darusentan was fluid retention/edema at 28% versus 12% in each of the other groups. More patients withdrew because of adverse events on darusentan as compared with placebo or guanfacine. We conclude that darusentan provided greater reduction in systolic BP in resistant hypertension patients as assessed by ambulatory BP monitoring, in spite of not meeting its coprimary end points. The results of this trial highlight the importance of ambulatory BP monitoring in the design of hypertension clinical studies.

RESUMO

BACKGROUND: Results of randomized controlled trials are consistent in showing reduced rates of stroke, heart failure and cardiovascular events in very old patients treated with antihypertensive drugs. However, inconsistencies exist with regard to the effect of these drugs on total mortality. METHODS: We performed a meta-analysis of available data on hypertensive patients 80 years and older by selecting total mortality as the main outcome. Secondary outcomes were coronary events, stroke, cardiovascular events, heart failure and cause-specific mortality. The common relative risk (RR) of active treatment versus placebo or no treatment was assessed using a random-effect model. Linear meta-regression was performed to explore the relationship between intensity of antihypertensive therapy and blood pressure (BP) reduction and the log-transformed value of total mortality odds ratios (ORs). RESULTS: The overall RR for total mortality was 1.06 (95% confidence interval 0.89-1.25), with significant heterogeneity between hypertension in the very elderly trial (HYVET) and the other trials. This heterogeneity was not explained by differences in the follow-up duration between trials. The meta-regression suggested that a reduction in mortality was achieved in trials with the least BP reductions and the lowest intensity of therapy. Antihypertensive therapy significantly reduced (P < 0.001) the risk of stroke (35%), cardiovascular events (27%) and heart failure (50%). Cause-specific mortality was not different between treated and untreated patients. CONCLUSION: Treating hypertension in very old patients reduces stroke and heart failure with no effect on total mortality. The most reasonable strategy is the one associated with significant mortality reduction; thiazides as first-line drugs with a maximum of two drugs.
