Effectiveness of Nurse Based Motivational Interviewing for smoking cessation in high risk cardiovascular outpatients: a randomized trial

Content Validity and Cognitive Testing in the Development of a Motivational Interviewing Self-Assessment Questionnaire

Aim

To develop and content validate a self-assessment questionnaire on motivational interviewing (MI) practice as the first stages in forming the questionnaire to be used in cross-sectional studies involving practitioners conducting the MI-based alcohol screening and brief intervention (ASBI).

Methods

A comprehensive mixed methods approach included a literature review, 3 rounds of expert panel (EP) opinions (n=10), cognitive testing (CT) with 10 MI-based ASBI practitioners, and questionnaire piloting with 31 MI-based ASBI practitioners. Based on the EP opinions in the second round, content validity indices (CVIs) and the modified kappa coefficient (k*) were calculated, focusing on the relevance and understandability of questions and comprehensiveness and meaningfulness of the response options. This analysis was performed in 2020, at the conclusion of the national "Together for a Responsible Attitude Towards Alcohol Consumption" ("Skupaj za odgovoren odnos do pitja alkohola", SOPA) project's pilot implementation.

Results

On a scale level, CVI values based on universal agreement for the entire questionnaire were high for 3/4 categories (S-CVI-UA>0.80), and CVI values based on average agreement were high across all categories (S-CVI-Ave>0.90). At the item level, CVI values (I-CVI) were never <0.50 (automatic item rejection), and the modified kappa value (k*) indicated poor validity for two items in the understandability category (k*=0.33). All problematic parts of the questionnaire were further tested and successfully modified based on the results of CT, and accepted in the third round of testing.

Conclusions

The final version of the questionnaire demonstrated appropriate content validity for use in studies among Slovenian MI-based ASBI practitioners and is now ready for further psychometric testing.

Using Behavior Change Interventions in Cardiac and Pulmonary Rehabilitation: Perspectives from Healthcare Professionals in the United Kingdom

This study explores healthcare professionals’ experiences of using behavior change interventions in clinical practice. Semi-structured qualitative interviews were conducted with 11 healthcare professionals working in a cardiac and pulmonary rehabilitation National Health Service Trust in the United Kingdom. Interviews were transcribed and analyzed using inductive thematic analysis. Four overarching themes representing healthcare practitioners’ perceptions of using behavior change interventions were identified: (1) reliance on experiential learning, (2) knowledge transition, (3) existing professional development programs, and (4) barriers and facilitators for continued professional development. The results are discussed in relation to the implications they may have for behavior change training in clinical healthcare practice. Healthcare professionals require bespoke and formalized training to optimize their delivery of behavior change interventions in cardiac and pulmonary rehabilitation. Doing so will enhance intervention fidelity and implementation that can potentially ameliorate patient rehabilitation outcomes.

Active Ingredients and Mechanisms of Change in Motivational Interviewing for Smoking Cessation in Patients With Coronary Artery Disease: A Mixed Methods Study

Background: For patients with coronary artery disease (CAD), smoking is an important risk factor for the recurrence of a cardiovascular event. Motivational interviewing (MI) may increase the motivation of the smokers to stop smoking. Data on MI for smoking cessation in patients with CAD are limited, and the active ingredients and working mechanisms of MI in smoking cessation are largely unknown. Therefore, this study was designed to explore active ingredients and working mechanisms of MI for smoking cessation in smokers with CAD, shortly after a cardiovascular event.

Methods: We conducted a qualitative multiple case study of 24 patients with CAD who participated in a randomized trial on lifestyle change. One hundred and nine audio-recorded MI sessions were coded with a combination of the sequential code for observing process exchanges (SCOPE) and the motivational interviewing skill code (MISC). The analysis of the cases consisted of three phases: single case analysis, cross-case analysis, and cross-case synthesis. In a quantitative sequential analysis, we calculated the transition probabilities between the use of MI techniques by the coaches and the subsequent patient statements concerning smoking cessation.

Results: In 12 cases, we observed ingredients that appeared to activate the mechanisms of change. Active ingredients were compositions of behaviors of the coaches (e.g., supporting self-efficacy and supporting autonomy) and patient reactions (e.g., in-depth self-exploration and change talk), interacting over large parts of an MI session. The composition of active ingredients differed among cases, as the patient process and the MI-coaching strategy differed. Particularly, change talk and self-efficacy appeared to stimulate the mechanisms of change “arguing oneself into change” and “increasing self-efficacy/confidence.”

Conclusion: Harnessing active ingredients that target the mechanisms of change “increasing self-efficacy” and “arguing oneself into change” is a good MI strategy for smoking cessation, because it addresses the ambivalence of a patient toward his/her ability to quit, while, after the actual cessation, maintaining the feeling of urgency to persist in not smoking in the patient.

Motivational Interviewing Produces Change Talk in Smokers with Serious Mental Illness

Change talk, or client language that is consistent with making a behavioral change, has been found to improve the efficacy of motivational interviewing (MI). It is not known, however, if change talk helps to explain MI's effect on instigating a quit attempt in smokers with serious mental illness. Methods: We measured change talk in smokers with a serious mental illness (SMI) randomized to receive either a single session adaptation of motivational interviewing or an interactive education intervention. We evaluated relationships between treatment condition, proportion of change talk, and study outcomes of quit attempts and willingness to follow up on treatment provider referrals. Results: Participants receiving the adaptation of motivational interviewing had higher proportions of change talk than participants in the interactive education condition. However, total proportion of change talk did not mediate the relationship between treatment and outcome, nor did it predict making a quit attempt or following up on a referral to contact a treatment provider. Conclusions: Our study found that motivational interviewing has the same change talk augmenting effect in individuals with SMI as those without SMI. Given that anhedonia, negative affect, and depressive symptoms are a major part of serious mental illnesses, it is encouraging that MI can generate change talk in this population. Future smoking cessation intervention trials with larger samples should investigate whether greater amounts of change talk lead to increased quit attempts in this population.

Self-management support in cardiovascular consultations by advanced practice nurses trained in motivational interviewing: An observational study

OBJECTIVE

This observational study explores advanced practice nurses' (APN) performance in secondary prevention and self-management support in patients with cardiovascular disease.

METHODS

Real-life consultations in three outpatient clinics were recorded on audio and analysed. First, discussed (sub)categories were determined using five categories of self-management: symptom management, treatment, biomedical cardiovascular risk factors, psychosocial consequences, and lifestyle changes. Second, the extent in which motivational interviewing aspects were applied was determined using the Behaviour Change Counselling Index (BECCI).

RESULTS

In total, 49 consultations performed by five female APNs were analysed. Physical topics were discussed in 98% and psychological subthemes in 41% of the consultations. Although not all components of motivational interviewing were applied, talking about current behaviour and behaviours that should change were discussed, and information was provided. Especially setting targets and exchanging ideas on how to reach behavioural goals were applied to a small extent.

CONCLUSION

Well-trained APNs in the current study do not carry out motivational interviewing in a structural and complete manner according to BECCI and do not discuss all self-management categories.

PRACTICE IMPLICATIONS

Psychological topics should be more integrated in providing self-management support by APNs and the application of motivational interviewing should be enhanced by regularly and repeated training.

A Nurse-led Approach to Improving Cardiac Lifestyle Modification in an Atrial Fibrillation Population

Atrial fibrillation (AF) is a major public health problem and the most common cardiac arrhythmia encountered in clinical practice at this time. AF is associated with numerous symptoms such as palpitations, shortness of breath, and fatigue, which can significantly reduce health-related quality of life and result in serious adverse cardiac outcomes. In light of this, the aim of the present pilot study was to test the feasibility of implementing a mobile health (mHealth) lifestyle intervention titled "Atrial Fibrillation and Cardiac Health: Targeting Improving Outcomes via a Nurse-Led Intervention (ACTION)," with the goal of improving cardiac health measures, AF symptom recognition, and self-management. As part of this study, participants self-identified cardiac health goals at enrollment. The nurse used web-based resources from the American Heart Association (Dallas, TX, USA), which included the Life's Simple 7® My Life Check® assessment, to quantify current lifestyle behavior change needs. Furthermore, on the My AFib Experience™ website (American Heart Association, Dallas, TX, USA), the patient used a symptom tracker tool to capture the date, time, frequency, and type of AF symptoms, and these data were subsequently reviewed by the cardiac nurse. Throughout the six-month intervention period, the cardiac nurse used a motivational interviewing approach to support participants' cardiac health goals. Ultimately, the ACTION intervention was tested in 53 individuals with AF (mean age: 59 ± 11 years; 76% male). Participants were predominantly overweight/obese (79%), had a history of hypertension (62%) or hyperlipidemia (61%), and reported being physically inactive/not preforming any type of regular exercise (52%). The majority (88%) of the participants had one or more Life's Simple 7® measures that could be improved. Most of the participants (98%) liked having a dedicated nurse to work with them on a biweekly basis via the mHealth portal. The most commonly self-reported symptoms were palpitations, fatigue/exercise intolerance, and dyspnea. Seventy percent of the participants had an improvement in their weight and blood pressure as documented within the electronic health record as well as a corresponding improvement in their Life's Simple 7® score at six months. On average, there was a three-pound (1.36-kg) decrease in weight and a 5-mmHg decrease in systolic blood pressure between baseline and at six months. In conclusion, this pilot work provides initial evidence regarding the feasibility of implementing the ACTION intervention and supports testing the ACTION intervention in a larger cohort of AF patients to inform existing AF guidelines and build an evidence base for reducing AF burden through lifestyle modification.

Developing nurses’ skills in motivational interviewing to promote a healthy lifestyle in patients with coronary artery disease

Background:

If nurses have the communication skills and the time, they can play an important role in increasing the intrinsic motivation of patients with coronary artery disease (CAD) to change their lifestyle. Motivational Interviewing (Mo-Int) can be used to further support this role. However, few nurses are sufficiently proficient in applying Mo-Int skills. Increasing these complex communication skills may contribute significantly to achieve lifestyle changes in CAD patients.

Aims:

The aim of this study was to evaluate the coaching of nurses to skilfully use Mo-Int in a secondary prevention programme for CAD patients.

Methods:

The design was a before–after study of a learning strategy as a follow-up on a short Mo-Int workshop. At (on average) four-monthly intervals, the nurses received, three times, feedback and coaching by telephone and email on their use of Mo-Int skills in audio-recorded conversations on lifestyle change with CAD patients. The Mo-Int consistency of the nurses’ communication skills was scored using the Motivational Interviewing Target Scheme 2.1 (range 0–32).

Results:

Of the 24 nurses, 13 completed all audio recordings. The mean change in Mo-Int consistency of these completers between the first and the last audio recording was 6.4 (95% confidence interval 3.2 to 9.5). This change indicates an improvement from ‘a small part of Motivational Interviewing practice’ to ‘a mainly sufficient degree of Motivational Interviewing practice’.

Conclusion:

A one-year follow-up on a Mo-Int workshop with feedback and coaching improves Mo-Int skills of nurses. Healthcare professionals should be aware of the importance of a follow-up on training in complex communication skills, to develop and preserve competency.

Nursing interventions for smoking cessation

BACKGROUND

Healthcare professionals, including nurses, frequently advise people to improve their health by stopping smoking. Such advice may be brief, or part of more intensive interventions.

OBJECTIVES

To determine the effectiveness of nursing-delivered smoking cessation interventions in adults. To establish whether nursing-delivered smoking cessation interventions are more effective than no intervention; are more effective if the intervention is more intensive; differ in effectiveness with health state and setting of the participants; are more effective if they include follow-ups; are more effective if they include aids that demonstrate the pathophysiological effect of smoking.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialized Register and CINAHL in January 2017.

SELECTION CRITERIA

Randomized trials of smoking cessation interventions delivered by nurses or health visitors with follow-up of at least six months.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data independently. The main outcome measure was abstinence from smoking after at least six months of follow-up. We used the most rigorous definition of abstinence for each trial, and biochemically-validated rates if available. Where statistically and clinically appropriate, we pooled studies using a Mantel-Haenszel fixed-effect model and reported the outcome as a risk ratio (RR) with a 95% confidence interval (CI).

MAIN RESULTS

Fifty-eight studies met the inclusion criteria, nine of which are new for this update. Pooling 44 studies (over 20,000 participants) comparing a nursing intervention to a control or to usual care, we found the intervention increased the likelihood of quitting (RR 1.29, 95% CI 1.21 to 1.38); however, statistical heterogeneity was moderate (I² = 50%) and not explained by subgroup analysis. Because of this, we judged the quality of evidence to be moderate. Despite most studies being at unclear risk of bias in at least one domain, we did not downgrade the quality of evidence further, as restricting the main analysis to only those studies at low risk of bias did not significantly alter the effect estimate. Subgroup analyses found no evidence that high-intensity interventions, interventions with additional follow-up or interventions including aids that demonstrate the pathophysiological effect of smoking are more effective than lower intensity interventions, or interventions without additional follow-up or aids. There was no evidence that the effect of support differed by patient group or across healthcare settings.

AUTHORS' CONCLUSIONS

There is moderate quality evidence that behavioural support to motivate and sustain smoking cessation delivered by nurses can lead to a modest increase in the number of people who achieve prolonged abstinence. There is insufficient evidence to assess whether more intensive interventions, those incorporating additional follow-up, or those incorporating pathophysiological feedback are more effective than one-off support. There was no evidence that the effect of support differed by patient group or across healthcare settings.

Effect of telling patients their "spirometric-lung-age" on smoking cessation in Japanese smokers

Background

Cigarette smoking remains a significant public health problem. However, current treatment programs have not yet succeeded in sufficiently reducing smoking rates. The study aimed to examine whether patients' recognition of "spirometric-lung-age (SLA)" estimated from spirometry data prompts smoking cessation.

Methods

From December 2010 to September 2011, participating smokers were prospectively enrolled into the standardized smoking cessation program (Visits 1-5 for 12 weeks) and assigned single-blindly to either SLA assessment or control groups. The SLA group was informed of the estimated age of their lungs from spirometry analysis and given an opportunity to recognize the difference from their actual chronological age, whereas the control group was not. The primary calculation of outcome was the smoking quit rate on Visit 5, whereas the secondary end-point was the proportion of patients who remained abstinent 1 year later.

Results

One hundred and twenty-six Japanese smokers (88 males) participated and were randomly assigned to the SLA group (n=52) or the control group (n=74). The smoking quit rate on Visit 5 was similar in the SLA assessment group and control group (59.6% vs. 41.9%; P=0.0700). However, the proportion of patients who remained abstinent 1 year later was similar in both groups (78.6% vs. 69.0%; P=0.5497). Multivariate logistic regression analysis after adjusting baseline characteristics demonstrated that telling patients their SLA, the use of varenicline, and age were significantly associated with smoking quit rate on Visit 5 whereas only age was associated with remaining abstinent 1 year later.

Conclusions

Telling patients their SLA can become a useful tool prompting smoking cessation among Japanese smokers although other factors such as pharmacotherapy and age also influence the cessation of smoking.

Effectiveness of motivational interviewing on lifestyle modification and health outcomes of clients at risk or diagnosed with cardiovascular diseases: A systematic review

BACKGROUND AND OBJECTIVE

Clinically, there is an increasing trend in using motivational interviewing as a counseling method to help clients with cardiovascular diseases to modify their unhealthy lifestyle in order to decrease the risk of disease occurrence. As motivational interviewing has gained increased attention, research has been conducted to examine its effectiveness. This review attempts to identify the best available evidence related to the effectiveness of motivational interviewing on lifestyle modification, physiological and psychological outcomes for clients at risk of developing or with established cardiovascular diseases.

DESIGN

Systematic review of studies incorporating motivational interviewing in modifying lifestyles, improving physiological and psychological outcomes for clients at risk of or diagnosed with cardiovascular diseases.

DATA SOURCES

Major English and Chinese electronic databases were searched to identify citations that reported the effectiveness of motivational interviewing. The searched databases included MEDLINE, British Nursing Index, CINAHL Plus, PsycINFO, SCOPUS, CJN, CBM, HyRead, WanFang Data, Digital Dissertation Consortium, and so on.

REVIEW METHOD

Two reviewers independently assessed the relevance of citations based on the inclusion criteria. Full texts of potential citations were retrieved for more detailed review. Critical appraisal was conducted by using the standardized critical appraisal checklist for randomized and quasi-randomized controlled studies from the Joanna Briggs Institute - Meta Analysis of Statistics Assessment and Review Instrument (JBI-MAStaRI).

RESULTS

After eligibility screening, 14 articles describing 9 studies satisfied the inclusion criteria and were included in the analysis. Only certain outcomes in certain studies were pooled for meta-analysis because of the large variability of the studies included, other findings were presented in narrative form. For lifestyle modification, the review showed that motivational interviewing could be more effective than usual care on altering smoking habits. For physiological outcomes, the review showed that motivational interviewing positively improved client's systolic and diastolic blood pressures but the result was not significant. For psychological outcomes, the review showed that motivational interviewing might have favorable effect on improving clients' depression. For other outcomes, the review showed that motivational interviewing did not differ from usual care or usual care was even more effective.

CONCLUSIONS

The review showed that motivational interviewing might have favorable effects on changing clients' smoking habits, depression, and three SF-36 domains. For the other outcomes, most of the results were inconclusive. Further studies should be performed to identify the optimal format and frequency of motivational interviewing. Primary research on the effectiveness of motivational interviewing on increasing clients' motivation and their actual changes in healthy behavior is also recommended.

Making the connection-factors influencing implementation of evidence supported and non-evaluated lifestyle interventions in healthcare: a multiple case study

Many implementation barriers relate to lifestyle interventions (LIs) being developed by scientists. Exploring whether implementation of non-evaluated LIs is less complicated, might offer insight how to improve the use of effective interventions. This study aimed to identify influencing factors for implementation and compare factors between evidence supported and non-evaluated LIs. Evidence-supported (n = 7) and non-evaluated LIs (n = 7) in hospitals, general practices and community care organizations were included as cases. Semi-structured interviews (n = 46) were conducted. Additionally, documents (n = 207) were collected describing intervention, implementation process, and policy. We used a stepwise approach to inductively identify factors, organize them by diffusion phase, and an existing framework. A total of 37 factors were identified. 'Dissemination' factors were mainly observed in evidence-supported LIs. 'Compatibility to existing structures' ('adoption'), 'funding' and 'connection to existing care processes' ('implementation') was factors identified in all cases. 'Quality control' and 'ongoing innovation' ('maintenance') were reported in evidence-supported interventions. In all domains of the framework factors were observed. Factors identified in this study are in line with the literature. The findings do not support the assumption that implementation of non-evaluated LIs is perceived as less complex.

Managing chronic pathologies with a stepped mHealth-based approach in clinical psychology and medicine

Chronic diseases and conditions typically require long-term monitoring and treatment protocols both in traditional settings and in out-patient frameworks. The economic burden of chronic conditions is a key challenge and new and mobile technologies could offer good solutions. mHealth could be considered an evolution of eHealth and could be defined as the practice of medicine and public health supported by mobile communication devices. mHealth approach could overcome limitations linked with the traditional, restricted, and highly expensive in-patient treatment of many chronic pathologies. Possible applications include stepped mHealth approach, where patients can be monitored and treated in their everyday contexts. Unfortunately, many barriers for the spread of mHealth are still present. Due the significant impact of psychosocial factors on disease evolution, psychotherapies have to be included into the chronic disease protocols. Existing psychological theories of health behavior change have to be adapted to the new technological contexts and requirements. In conclusion, clinical psychology and medicine have to face the "chronic care management" challenge in both traditional and mHealth settings.

An Adaptation of Motivational Interviewing Increases Quit Attempts in Smokers With Serious Mental Illness

INTRODUCTION

Smokers with serious mental illness (SMI) have a high smoking prevalence and a low quit rate. Motivational interviewing (MI) is an empirically supported approach for addressing substance use disorders and may motivate smokers with SMI to quit.

METHODS

We randomized smokers (N = 98) with SMI to receive a single 45-minute session of (1) MI with personalized feedback or (2) interactive education. We hypothesized that participants receiving the MI intervention would be more likely to follow-up on a referral for tobacco dependence treatment, to make a quit attempt, and to quit smoking than those receiving the interactive educational intervention.

RESULTS

Smokers receiving an MI intervention were significantly more likely to make a quit attempt by the 1-month follow-up (34.7% vs. 14.3%; OR = 4.39 [95% CI = 1.44 to 13.34], P = .009); however, these quit attempts did not translate into abstinence. In addition, 32.7% of those receiving MI followed-up on a referral for tobacco dependence treatment (vs. 20.4% receiving interactive education; OR = 2.02 [95% CI = 0.76 to 3.55], P = .157). MI Treatment Integrity Code ratings indicated that the interventions were easily distinguishable from each other and that MI was delivered with proficiency. Despite the intervention's brevity, participants reported high levels of therapeutic alliance with their therapist.

CONCLUSIONS

A brief adaptation of MI with personalized feedback appears to be a promising approach for increasing quit attempts in smokers with SMI, but future research is required to determine how to best help smokers with SMI to attain sustained abstinence.

Experiences of adult smokers from the concepts of smoking: A content analysis

BACKGROUND

Smoking cigarettes is a risk factor for many physical and mental diseases. About five million people die of smoking every year. Understanding the concept of cigarette smoking can help people develop their knowledge with regard to smoking. A qualitative research seems essential to detect these concepts. Therefore, the present study aims to take into account the experience of adult smokers with regard to the concept of smoking.

MATERIALS AND METHODS

This is a qualitative content analysis study conducted on 12 smokers in four selected cities in Iran. Data were collected by in-depth, semi-structured interviews, transcribed verbatim, and simultaneously coded. Subsequently, they were analyzed using the content analysis method.

RESULTS

In the present study, eight concepts (themes), 22 subcategories, and 81 codes have emerged. The obtained concepts are physics of a cigarette, addiction and dependency, habit, feel the need, pleasure, seeking peace, mental involvement, and self-induction.

CONCLUSIONS

The participants' experiences with regard to cigarette smoking can affect their understanding of the concepts of smoking. The understanding of these concepts by nurses and smokers can enhance their knowledge about the existing facts of smoking, which can act as a foundation for designing preventive methods and smoking cessation programs.

A Nurse-Led Multidisciplinary Intervention to Improve Cardiovascular Disease Profile of Patients

The aim of this study was to evaluate the impact of a structured screening and nurse-based intervention on cardiovascular risk factors. In patients with established cardiovascular disease, a cardiovascular risk profile was assessed, and lifestyle was evaluated by using an automated questionnaire. A multidisciplinary team proposed an integral individualized plan of care on the basis of these assessments. During follow-up, a nurse-led lifestyle intervention program and the best medical treatment were offered. A total of 328 outpatients were included. After screening, a follow-up term of at least 1 year was reached in 176 patients (59.9%). Low-density lipoprotein cholesterol and systolic blood pressure were significantly reduced. A reduction in the amount of smoking, alcohol consumption, and unhealthy eating habits was observed. However, the amount of physical activity was unaffected, and body mass was increased. A structural evaluation of cardiovascular risk factors and an integrated nurse-led approach can successfully reduce risk in cardiovascular patients.

Nursing interventions for smoking cessation

BACKGROUND

Healthcare professionals, including nurses, frequently advise people to improve their health by stopping smoking. Such advice may be brief, or part of more intensive interventions.

OBJECTIVES

To determine the effectiveness of nursing-delivered smoking cessation interventions.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group specialized Register and CINAHL in June 2013.

SELECTION CRITERIA

Randomized trials of smoking cessation interventions delivered by nurses or health visitors with follow-up of at least six months.

DATA COLLECTION AND ANALYSIS

Two authors extracted data independently. The main outcome measure was abstinence from smoking after at least six months of follow-up. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. Where statistically and clinically appropriate, we pooled studies using a Mantel-Haenszel fixed-effect model and reported the outcome as a risk ratio (RR) with a 95% confidence interval (CI).

MAIN RESULTS

Forty-nine studies met the inclusion criteria. Pooling 35 studies (over 17,000 participants) comparing a nursing intervention to a control or to usual care, we found the intervention to increase the likelihood of quitting (RR 1.29; 95% CI 1.20 to 1.39). In a subgroup analysis the estimated effect size was similar for the group of seven studies using a particularly low intensity intervention but the confidence interval was wider. There was limited indirect evidence that interventions were more effective for hospital inpatients with cardiovascular disease than for inpatients with other conditions. Interventions in non-hospitalized adults also showed evidence of benefit. Eleven studies comparing different nurse-delivered interventions failed to detect significant benefit from using additional components. Six studies of nurse counselling on smoking cessation during a screening health check or as part of multifactorial secondary prevention in general practice (not included in the main meta-analysis) found nursing intervention to have less effect under these conditions.

AUTHORS' CONCLUSIONS

The results indicate the potential benefits of smoking cessation advice and/or counselling given by nurses, with reasonable evidence that intervention is effective. The evidence for an effect is weaker when interventions are brief and are provided by nurses whose main role is not health promotion or smoking cessation. The challenge will be to incorporate smoking behaviour monitoring and smoking cessation interventions as part of standard practice so that all patients are given an opportunity to be asked about their tobacco use and to be given advice and/or counselling to quit along with reinforcement and follow-up.

Multifactorial intervention with nurse practitioners does not change cardiovascular outcomes in patients with chronic kidney disease

Strict implementation of guidelines directed at multiple targets reduces vascular risk in diabetic patients. Whether this also applies to patients with chronic kidney disease (CKD) is uncertain. To evaluate this, the MASTERPLAN Study randomized 788 patients with CKD (estimated GFR 20-70 ml/min) to receive additional intensive nurse practitioner support (the intervention group) or nephrologist care (the control group). The primary end point was a composite of myocardial infarction, stroke, or cardiovascular death. During a mean follow-up of 4.62 years, modest but significant decreases were found for blood pressure, LDL cholesterol, anemia, proteinuria along with the increased use of active vitamin D or analogs, aspirin and statins in the intervention group compared to the controls. No differences were found in the rate of smoking cessation, weight reduction, sodium excretion, physical activity, or glycemic control. Intensive control did not reduce the rate of the composite end point (21.3/1000 person-years in the intervention group compared to 23.8/1000 person-years in the controls (hazard ratio 0.90)). No differences were found in the secondary outcomes of vascular interventions, all-cause mortality or end-stage renal disease. Thus, the addition of intensive support by nurse practitioner care in patients with CKD improved some risk factor levels, but did not significantly reduce the rate of the primary or secondary end points.
