The effectiveness of peer health coaching in improving glycemic control among low-income patients with diabetes: protocol for a randomized controlled trial

Background  

Although self-management support improves diabetes outcomes, it is not consistently provided in health care settings strained for time and resources. One proposed solution to personnel and funding shortages is to utilize peer coaches, patients trained to provide diabetes education and support to other patients. Coaches share similar experiences about living with diabetes and are able to reach patients within and beyond the health care setting. Given the limited body of evidence that demonstrates peer coaching significantly improves chronic disease care, this present study examines the impact of peer coaching delivered in a primary care setting on diabetes outcomes.     

The effectiveness of a life style modification and peer support home blood pressure monitoring in control of hypertension: protocol for a cluster randomized controlled trial

Background

Death rates due to hypertension in low and middle income countries are higher compared to high income countries. The present study is designed to combine life style modification and home blood pressure monitoring for control of hypertension in the context of low and middle income countries.

Methods

The study is a two armed, parallel group, un-blinded, cluster randomized controlled trial undertaken within lower income areas in Kuala Lumpur. Two housing complexes will be assigned to the intervention group and the other two housing complexes will be allocated in the control group. Based on power analysis, 320 participants will be recruited. The participants in the intervention group (n = 160) will undergo three main components in the intervention which are the peer support for home blood pressure monitoring, face to face health coaching on healthy diet and demonstration and training for indoor home based exercise activities while the control group will receive a pamphlet containing information on hypertension. The primary outcomes are systolic and diastolic blood pressure. Secondary outcome measures include practice of self-blood pressure monitoring, dietary intake, level of physical activity and physical fitness.

Discussion

The present study will evaluate the effect of lifestyle modification and peer support home blood pressure monitoring on blood pressure control, during a 6 month intervention period. Moreover, the study aims to assess whether these effects can be sustainable more than six months after the intervention has ended.

     

The effects of pseudoephedrine on blood pressure in patients with controlled, uncomplicated hypertension: a randomized, double-blind, placebo-controlled trial

Pseudoephedrine is frequently used as a decongestant. Because of concern about the safety of pseudoephedrine in hypertensive patients, a clinical trial was conducted to determine whether blood pressure control was actually affected by this drug in a selected group of patients with hypertension. Twenty-nine patients with controlled, uncomplicated hypertension, who received drug therapy and ranged in age from 25 to 50 years, were randomized to a treatment or a control group. Subjects took either 60 mg of pseudoephedrine or placebo capsules four times a day for 3 days. From 0800 hours until 2200 hours each day, the subjects obtained hourly blood pressure measurements using a portable sphygmomanometer. An analysis of variance with repeated measures was calculated to determine group differences for systolic and diastolic readings. No statistically or clinically significant differences were found. Therapeutic doses of pseudoephedrine did not adversely affect control of hypertension in these selected patients.     

Strategies for controlling blood pressure among low-income populations in Georgia

Background

In Georgia an estimated 32% of blacks and 28% of whites have high blood pressure. In 2004 the rate of death from stroke in Georgia was 12% higher than the national average, and blacks in the state have a 1.4 times greater rate of death from stroke than that of whites.

Context

The Georgia legislature funds the Stroke and Heart Attack Prevention Program (SHAPP) to provide treatment and medications for indigent Georgians. The median rate of blood pressure (BP) control among SHAPP enrollees is approximately 60%, compared with the national average of 35%.

Methods

SHAPP was evaluated through interviews with key health care and administrative staff and through focus groups of patients in two clinics.

Consequences

Outcomes for patients were increased knowledge of their BP and improved compliance with taking medication and keeping clinic appointments.

Interpretation

Successful components of SHAPP include an easy enrollment process; affordable medication; use of evidence-based, documented protocols and patient tracking systems; routine follow-up of patients; and effective communication between staff and patients. Challenges and recommendations for improvement are identified.     

Coffee, blood pressure and plasma lipids: a randomized controlled trial

A randomized controlled trial was conducted to examine the effects of coffee (as commonly drunk in Britain) on blood pressure and plasma lipids in healthy subjects. Fifty-four subjects followed three regimens successively, the order being randomized according to a Latin square design: five or more cups of coffee daily for 4 weeks; five or more cups of decaffeinated coffee daily for 4 weeks but no ordinary coffee; no coffee for 4 weeks. Coffee appeared to cause a small rise (of 3 mm Hg) in recumbent systolic blood pressure; this effect was less than, and obscured by, changes induced by posture and mild stress. No consistent changes attributable to coffee were found in diastolic blood pressure or pulse rate. Small changes in the expected directions occurred in plasma high density lipoprotein (HDL) cholesterol and apolipoprotein AI (decrease), and in total cholesterol, non-HDL cholesterol and apolipoprotein B (increase), but none of these were statistically significant. The effect of coffee on risk of heart disease in Britain is probably small.     

Nutrition education intervention for dependent patients: protocol of a randomized controlled trial

ABSTRACT: BACKGROUND: Malnutrition in dependent patients has a high prevalence and can influence the prognosis associated with diverse pathologic processes, decrease quality of life, and increase morbidity-mortality and hospital admissions. The aim of the study is to assess the effect of an educational intervention for caregivers on the nutritional status of dependent patients at risk of malnutrition. METHODS: Intervention study with control group, randomly allocated, of 200 patients of the Home Care Program carried out in 8 Primary Care Centers (Spain). These patients are dependent and at risk of malnutrition, older than 65, and have caregivers. The socioeconomic and educational characteristics of the patient and the caregiver are recorded. On a schedule of 0-6-12 months, patients are evaluated as follows: Mini Nutritional Assessment (MNA), food intake, dentures, degree of dependency (Barthel test), cognitive state (Pfeiffer test), mood status (Yesavage test), and anthropometric and serum parameters of nutritional status: albumin, prealbumin, transferrin, haemoglobin, lymphocyte count, iron, and ferritin. Prior to the intervention, the educational procedure and the design of educational material are standardized among nurses. The nurses conduct an initial session for caregivers and then monitor the education impact at home every month (4 visits) up to 6 months. The North American Nursing Diagnosis Association (NANDA) methodology will be used. The investigators will study the effect of the intervention with caregivers on the patient's nutritional status using the MNA test, diet, anthropometry, and biochemical parameters. Bivariate normal test statistics and multivariate models will be created to adjust the effect of the intervention. The SPSS/PC program will be used for statistical analysis. DISCUSSION: The nutritional status of dependent patients has been little studied. This study allows us to know nutritional risk from different points of view: diet, anthropometry and biochemistry in dependent patients at nutritional risk and to assess the effect of a nutritional education intervention. The design with random allocation, inclusion of all patients, validated methods, caregivers' education and standardization between nurses allows us to obtain valuable information about nutritional status and prevention.

The effectiveness of a training for patients with unexplained physical symptoms: protocol of a cognitive behavioral group training and randomized controlled trial

Background  

In primary care, up to 74% of physical symptoms is classified as unexplained. These symptoms can cause high levels of distress and healthcare utilization. Cognitive behavioral therapy has shown to be effective, but does not seem to be attractive to patients. An exception herein is a therapy based on the consequences model, which distinguishes itself by its labeling of psychosocial distress in terms of consequences rather than as causes of physical symptoms. In secondary care, 81% of the patients accepts this therapy, but in primary care the outcome is poor. We assume that positive outcome can also be reached in primary care, when the consequences model is modified and used bottom-up in an easily accessible group training, in which patients are relieved of being blamed for their symptoms. Our aim is to investigate the (cost-)effectiveness of this training.     

The cost of home air-fluidized therapy for pressure sores. A randomized controlled trial

BACKGROUND. Recurrent pressures sores are a serious problem that often cause chronically ill patients to be hospitalized. We hypothesized that home air-fluidized bed therapy may be a safe and effective way to treat these patients, thus avoiding the costs of hospitalization. METHODS. One hundred twelve patients with 3rd or 4th stage pressure sores were randomly assigned to 36 weeks of either (1) home air-fluidized bed therapy that included the services of a visiting nurse specialist as long as the patient had 3rd or 4th stage sores, or (2) conventional therapy. RESULTS. Compared with patients in the control group, patients receiving air-fluidized bed therapy spent fewer days in the hospital (11.4 days vs 25.5 days, P less than .01) and used fewer total inpatient resources, as reflected both in charges ($13,263 vs $25,736, P less than .05) and in Medicare DRG and physician payments ($6,646 vs $12,131, P less than .05). Total resources used (inpatient and outpatient) were lower for patients treated with air-fluidized bed therapy, but the difference was not statistically significant. Clinical outcomes were similar. CONCLUSIONS. Home air-fluidized bed therapy is safe, reduces hospitalizations, is no more costly than alternative therapy, and allows the patients to receive their needed care in a more desirable, nonhospital setting.

The effectiveness of brief personalized normative feedback in reducing alcohol-related problems amongst University students: protocol for a randomized controlled trial

Background  

Studies have shown that university/college students tend to have an exaggerated view of the quantities of alcohol being consumed by their peers. Making students aware of this misperception may help change behaviour and reduce problem drinking.     

Motivational Interviewing for encouraging quit attempts among unmotivated smokers: Study protocol of a randomized, controlled, efficacy trial

ABSTRACT: BACKGROUND: Although current clinical practice guidelines recommend Motivational Interviewing for use with smokers not ready to quit, the strength of evidence for its use is rated as not optimal. The purpose of the present study is to address key methodological limitations of previous studies by ensuring fidelity in the delivery of the Motivational Interviewing intervention, using an attention-matched control condition, and focusing on unmotivated smokers whom meta-analyses have indicated may benefit most from Motivational Interviewing. It is hypothesized that MI will be more effective at inducing quit attempts and smoking cessation at 6-month follow-up than brief advice to quit and an intensity-matched health education condition. METHODS: A sample of adult community resident smokers (N= 255) who report low motivation and readiness to quit are being randomized using a 2:2:1 treatment allocation to Motivational Interviewing, Health Education, or Brief Advice. Over 6 months, participants in Motivational Interviewing and Health Education receive 4 individual counseling sessions and participants in Brief Advice receive one brief in-person individual session at baseline. Rigorous monitoring and independent verification of fidelity will assure the counseling approaches are distinct and delivered as planned. Participants complete surveys at baseline, week 12 and 6-month follow-up to assess demographics, smoking characteristics, and smoking outcomes. Participants who decide to quit are provided with a self-help guide to quitting, help with a quit plan, and free pharmacotherapy. The primary outcome is self-report of one or more quit attempts lasting at least 24 hours between randomization and 6-month follow-up. The secondary outcome is biochemically confirmed 7-day point prevalence cessation at 6-month follow-up. Hypothesized mediators of the presumed treatment effect on quit attempts are greater perceived autonomy support and autonomous motivation. Use of pharmacotherapy is a hypothesized mediator of Motivational Interviewing's effect on cessation. DISCUSSION: This trial will provide the most rigorous evaluation to date of Motivational Interviewing's efficacy for encouraging unmotivated smokers to make a quit attempt. It will provide also provide effect-size estimates of MI's impact on smoking cessation to inform future clinical trials and inform the clinical practice guidelines.

Nurse-led adherence support in hypertension: a randomized controlled trial

BACKGROUND: Lack of medication adherence is a common reason for poor control of blood pressure in the community, increasing the risk of heart attacks and strokes. OBJECTIVE: To evaluate the effect of nurse-led adherence support for people with uncontrolled high blood pressure compared with usual care. METHODS: We recruited 245 women and men with uncontrolled hypertension (> or = 150/90 mmHg) from 21 general practices in Bristol, UK. Participants were randomized to receive nurse-led adherence support or usual care alone. Main outcome measures were adherence to medication ('timing compliance') and blood pressure. RESULTS: Mean baseline timing compliance (+/- SD) was high in both the intervention (90.8 +/- 15.6%) and the control group (94.5 +/- 7.6%). There was no evidence of an effect of the intervention on timing compliance at follow-up (adjusted difference in means -1.0%; 95% confidence interval (CI) -5.1 to 3.1). There was also no difference at follow-up between the groups with regard to systolic blood pressure (-2.7 mmHg; 95% CI -7.2 to 1.8) or diastolic blood pressure (0.2 mmHg; 95% CI -1.9 to 2.3). Projected costs for the primary care sector per consultation were 6.60 pound sterling for the intervention compared with 5.08 pound sterling for usual care. CONCLUSION: In this study, adherence to blood pressure medication was much higher than previously reported. There was no evidence of an effect of nurse-led adherence support on medication adherence or blood pressure compared with usual care. Nurse-led adherence support was also more expensive from a primary care perspective.     

Integration of depression and hypertension treatment: a pilot, randomized controlled trial

PURPOSE We wanted to examine whether integrating depression treatment into care for hypertension improved adherence to antidepressant and antihypertensive medications, depression outcomes, and blood pressure control among older primary care patients.METHODS Older adults prescribed pharmacotherapy for depression and hypertension from physicians at a large primary care practice in West Philadelphia were randomly assigned to an integrated care intervention or usual care. Outcomes were assessed at baseline, 2, 4, and 6 weeks using the Center for Epidemiologic Studies Depression Scale (CES-D) to assess depression, an electronic monitor to measure blood pressure, and the Medication Event Monitoring System to assess adherence.RESULTS In all, 64 participants aged 50 to 80 years participated. Participants in the integrated care intervention had fewer depressive symptoms (CES-D mean scores, intervention 9.9 vs usual care 19.3; P <.01), lower systolic blood pressure (intervention 127.3 mm Hg vs usual care 141.3 mm Hg; P <.01), and lower diastolic blood pressure (intervention 75.8 mm Hg vs usual care 85.0 mm Hg; P <.01) compared with participants in the usual care group at 6 weeks. Compared with the usual care group, the proportion of participants in the intervention group who had 80% or greater adherence to an antidepressant medication (intervention 71.9% vs usual care 31.3%; P <.01) and to an antihypertensive medication (intervention 78.1% vs usual care 31.3%; P <.001) was greater at 6 weeks.CONCLUSION A pilot, randomized controlled trial integrating depression and hypertension treatment was successful in improving patient outcomes. Integrated interventions may be more feasible and effective in real-world practices, where there are competing demands for limited resources.     

Infant health effects of a nurse–community health worker home visitation programme: a randomized controlled trial

Background Home visiting is supported as a way to improve child health and development. Home visiting has been usually provided by nurses or community health workers (CHWs). Few studies compared the child health advantages of a nurse–CHW team approach over nurse prenatal and postnatal home visiting. Methods A randomized trial was conducted with Medicaid‐insured pregnant women in Kent County, Michigan. Pregnant women were assigned to a team intervention including nurse–CHW home visitation, or standard community care (CC) including nurse home visitation. Morbidity was assessed in 530 infants over their first 12 months of life from medical claims and reported by the mother. Results There were no differences in overall child health between the nurse–CHW intervention and the CC arm over the first year of life. There were fewer mother‐reported asthma/wheezing/croup diagnostics in the team intervention group among infants whose mothers have low psychosocial resources (13% vs. 27%, P = 0.01; adjusted OR = 0.4, P = 0.01). There were no differences in diagnosed asthma/wheezing/croup documented by medical claims. There were no differences in immunizations, hospitalizations and ear infections. Conclusions There was no strong evidence that infant health was improved by the addition of CHWs to a programme of CC that included nurse home visitation. Targeting such interventions at common health problems of infancy and childhood or at diagnosed chronic conditions may prove more successful.     

Evaluating a selective prevention programme for binge drinking among young adolescents: study protocol of a randomized controlled trial

Background  

In comparison to other Europe countries, Dutch adolescents are at the top in drinking frequency and binge drinking. A total of 75% of the Dutch 12 to 16 year olds who drink alcohol also engage in binge drinking. A prevention programme called Preventure was developed in Canada to prevent adolescents from binge drinking. This article describes a study that aims to assess the effects of this selective school-based prevention programme in the Netherlands.     

Promoting uptake of influenza vaccination among health care workers: a randomized controlled trial

In a randomized controlled trial, an intensive promotional campaign failed to increase the uptake of vaccination against influenza among health care workers. The uptake of vaccination was low.     

Public health in managed care: a randomized controlled trial of the effectiveness of postcard reminders.

OBJECTIVES: This study evaluated the effectiveness of an annual public health intervention in a managed care setting. METHODS: Managed care organization members 65 years and older who received influenza immunization in 1996 were randomized to an intervention group (mailed a postcard reminder to receive an influenza vaccination in 1997) or a control group (no postcard). Vaccination rates for both groups were assessed monthly. RESULTS: Members receiving the intervention were no more likely to be immunized (78.6%) than members of the control group (77.2%, P = .222). Members were vaccinated at the same pace regardless of vaccination history and postcard intervention status. CONCLUSIONS: Postcard reminders were not an effective intervention among seniors who had been vaccinated the previous year.     

Small individual loans and mental health: a randomized controlled trial among South African adults

Background  

In the developing world, access to small, individual loans has been variously hailed as a poverty-alleviation tool – in the context of "microcredit" – but has also been criticized as "usury" and harmful to vulnerable borrowers. Prior studies have assessed effects of access to credit on traditional economic outcomes for poor borrowers, but effects on mental health have been largely ignored.     

The effectiveness of "Exercise on Prescription" in stimulating physical activity among women in ethnic minority groups in the Netherlands: protocol for a randomized controlled trial

Background  

Lack of physical activity is an important risk factor for overweight, diabetes, cardiovascular disease and other chronic conditions. In the Netherlands, ethnic minority groups are generally less physically active and rate their own health poorer compared to ethnic Dutch. This applies in particular to women. For this reason women from ethnic minority groups are an important target group for interventions to promote physical activity.
