Effect of a smartphone intervention as a secondary prevention for use among university students with unhealthy alcohol use: randomised controlled trial

OBJECTIVE

To estimate the effects of providing access to an alcohol intervention based on a smartphone.

DESIGN

Randomised controlled trial..

SETTING

Four higher education institutions in Switzerland.

PARTICIPANTS

1770 students (≥18 years) who screened positive for unhealthy alcohol use (ie, a score on the alcohol use disorders identification test-consumption (AUDIT-C) of ≥4 for men and ≥3 for women) were randomly assigned by 1:1 allocation ratio in blocks of 10.

INTERVENTION

Providing access to a brief, smartphone based alcohol intervention.

OUTCOME MEASURES

The primary outcome studied was number of standard drinks per week at six months and the secondary outcome was number of heavy drinking days (past 30 days). Additional outcomes were maximum number of drinks consumed on one occasion, alcohol related consequences, and academic performance. Follow-up assessments occurred at months three, six, and 12. Data were analysed by intention to treat and by using generalised linear mixed models with random intercepts for the recruitment site and participants nested within the recruitment site, and with intervention (v control), time (three months v six months; 12 months v six months), and baseline outcome values as fixed effects.

RESULTS

Between 26 April 26 2021 and 30 May 2022, 1770 participants (intervention group (n=884); control group (n=886)) were included. Mean age was 22.4 years (standard deviation 3.07); 958 (54.1%) were women; and 1169 (66.0%) were undergraduate students, 533 (30.1%) were studying for a master's degree, 43 (2.4%) were studying for a doctorate, and 25 (1.4%) were students of other higher education programme. The baseline mean number of standard drinks per week was 8.59 (standard deviation 8.18); the baseline number of heavy drinking days was 3.53 (4.02). Of 1770 participants, follow-up rates were 1706 (96.4%) at three months, 1697 (95.9%) at six months, and 1660 (93.8%) at 12 months. Of 884 students randomly assigned to the intervention group, 738 (83.5%) downloaded the smartphone application. The intervention had a significant overall effect on the number of standard drinks per week (incidence rate ratio 0.90 (95% confidence interval 0.85 to 0.96)), heavy drinking days (0.89 (0.83 to 0.96)), and the maximum number of drinks consumed on one occasion (0.96 (0.93 to 1.00), P=0.029), indicating significantly lower drinking outcomes in the intervention group than in the control group during the follow-up period. The intervention did not affect alcohol related consequences or academic performance.

CONCLUSIONS

Providing access to the smartphone application throughout the 12 month follow-up was effective at limiting the average drinking volume of university students who had self-reported unhealthy alcohol use at baseline.

Quality and Presence of Behaviour Change Techniques in Mobile Apps for the Mediterranean Diet: A Content Analysis of Android Google Play and Apple App Store Apps

Smartphone apps might represent an opportunity to promote adherence to the Mediterranean diet (MedDiet). This study aimed to evaluate the quality of commercially available apps for the MedDiet and the presence of behavioural change techniques (BCTs) used by these apps. A systematic search was conducted on the Apple App and Google Play stores in November 2021. Apps were included if they provided information on the MedDiet or if their objective was to promote a healthy lifestyle through adherence to the MedDiet. Eligible apps were independently evaluated by two reviewers with regard to their quality (engagement, functionality, aesthetics and information quality) using the 5-point Mobile App Rating Scale (MARS; with higher scores indicating higher quality), and the presence of BCTs using an established 26-item BCT taxonomy. Of the 55 analysed apps, 52 (94.5%) were free, 50 (90.9%) provided recipe ideas, 29 (52.7%) provided meal plans, and 22 (40%) provided information on the health benefits of the MedDiet. The overall quality mean MARS score was 2.84 (standard deviation (SD) = 0.42), with functionality being the highest scored MARS domain (mean = 3.58, SD = 0.44) and engagement the lowest (mean = 2.29, SD = 0.61). The average number of BCTs in the analysed apps was 2.3 (SD = 1.4; range: 0-6 per app). The number of BCTs was positively correlated with app information quality (rrho = 0.269, p = 0.047), overall MARS score (rrho = 0.267, p = 0.049), app subjective quality (rrho = 0.326, p = 0.015) and app-specific quality (rrho = 0.351, p = 0.009). These findings suggest that currently available apps might provide information on the MedDiet, but the incorporation of more BCTs is warranted to maximise the potential for behaviour change towards the MedDiet.

Smartphone-based secondary prevention intervention for university students with unhealthy alcohol use identified by screening: study protocol of a parallel group randomized controlled trial

BACKGROUND

Unhealthy alcohol use is a leading cause of morbidity and mortality among young people, including university students. Delivering secondary prevention interventions against unhealthy alcohol use is challenging. Information technology has the potential to reach large parts of the general population. The present study is proposed to test a proactive secondary prevention smartphone-based intervention against unhealthy alcohol use.

METHODS

This is a parallel-group, randomized controlled trial (1:1 allocation ratio) among 1696 university students with unhealthy alcohol use, identified by screening and followed up at 3, 6, and 12 months. Participants will be randomized to receive access to a smartphone-based intervention or to a no intervention control condition. The primary outcome will be self-reported volume of alcohol drunk over the past 30 days, reported as the mean number of standard drinks per week over the past 30 days, measured at 6 months. Secondary outcomes will be number of heavy drinking days over the past 30 days, at 6 months. Additional outcomes will be maximum number of drinks on any day over the past 30 days, alcohol-related consequences (measured using the Short Inventory of Problems (SIP-2R), and academic performance.

DISCUSSION

The aim of this trial is to close the evidence gap on the efficacy of smartphone-based secondary prevention interventions. If proven effective, smartphone-based interventions have the potential to reach a large portion of the population, completing what is available on the Internet.

Electronic screening and brief intervention for unhealthy alcohol use in primary care waiting rooms - A pilot project

Background: In primary care, electronic self-administered screening and brief interventions for unhealthy alcohol may overcome some of the implementation barriers of face-to-face intervention. We developed an anonymous electronic self-administered screening brief intervention device for unhealthy alcohol use and assessed its feasibility and acceptability in primary care practice waiting rooms. Two modes of delivery were compared: with or without the presence of a research assistant (RA) to make patients aware of the device's presence and help users. Using the device was optional. Methods: The devices were placed in 10 participating primary care practices waiting rooms for 6 weeks, and were accessible on a voluntary basis. Number of appointments by each practice during the course of the study was recorded. Access to the electronic brief intervention was voluntary among those who screened positive. Screening and brief intervention rates and characteristics of users were compared across the modes of delivery. Results: During the study, there were 7270 appointments and 1511 individuals used the device (20.8%). Mean age of users was 45.3 (19.5), and 57.9% screened positive for unhealthy alcohol use. Of them, 53.8% accessed the brief intervention content. The presence of the RA had a major impact on the device's usage (59.6% vs 17.4% when absent). When the RA was present, participants were less likely to screen positive (49.4% vs 60.7%, P = 0.0003) but more likely to access the intervention (62.7% vs 51.4%, P = 0.009). Results from the satisfaction survey indicated that users found the device easy to use (93.5%), questions useful (89-95%) and 77.2% reported that their friends would be willing to use it. Conclusions: This pilot project indicates that the implementation of an electronic screening and brief intervention device for unhealthy alcohol is feasible and acceptable in primary care practices but that, without human support, its use is rather limited.

Smartphone application for unhealthy alcohol use: Pilot randomized controlled trial in the general population

BACKGROUND

There is limited evidence of the efficacy of smartphone applications to reduce unhealthy alcohol use. We tested the efficacy of providing access to a smartphone-based brief intervention for unhealthy alcohol use.

METHODS

We conducted a two parallel-group randomized controlled trial with follow-up at 6 months, among 977 individuals with an Alcohol Use Disorder Identification Test ≥8 and drinking 15 or more drinks/week. Participants were randomized to receive (or not) access to a smartphone application consisting of personalized feedback, risk assessment and self-monitoring. The primary outcome was the mean number of drinks/week. An intention to treat analysis (ITT) and a per protocol analysis (PP) were conducted.

RESULTS

Mean age of participants was 34.2(9.8), 46% were female. The baseline mean number of drinks per week was 28.9(16.7). Results differed by type of analysis: ITT: all 977 participants were included in the analysis. Follow-up rate was 70.7% (n = 691). There was no significant intervention effect: the Incidence Rate Ratio (IRR) (95%CI) for number of drinks per week was 0.93(0.84; 1.03). PP: 702 participants were included in the analysis. Follow-up rate was 78.1% (n = 548). There was a significant intervention effect: the IRR for number of drinks per week was 0.88(0.78; 0.99).

CONCLUSIONS

Providing access to a smartphone-based brief intervention had no impact on drinking at 6 months and does not appear to be an effective intervention in reducing drinking. Those who downloaded the app appear to benefit from it, nevertheless downloads were limited and further development of similar apps should focus on increasing use.

Effectiveness of online interventions in preventing depression: a protocol for systematic review and meta-analysis of randomised controlled trials

INTRODUCTION

Although evidence exists for the efficacy of psychosocial interventions in preventing depression, little is known about its prevention through online interventions. The objective of this study is to conduct a systematic review and meta-analysis of randomised controlled trials assessing the effectiveness of online interventions in preventing depression in heterogeneous populations.

METHODS AND ANALYSIS

We will conduct a systematic review and meta-analysis of randomised controlled trials that will be identified through searches of PubMed, PsycINFO, WOS, Scopus, OpenGrey, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and Australia New Zealand Clinical Trials Register . We will also search the reference lists provided in relevant studies and reviews. Experts in the field will be contacted to obtain more references. Two independent reviewers will assess the eligibility criteria of all articles, extract data and determine their risk of bias (Cochrane Collaboration Tool). Baseline depression will be required to have been discarded through standardised interviews or validated self-reports with standard cut-off points. The outcomes will be the incidence of new cases of depression and/or the reduction of depressive symptoms as measured by validated instruments. Pooled standardised mean differences will be calculated using random-effect models. Heterogeneity and publication bias will be estimated. Predefined sensitivity and subgroup analyses will be performed. If heterogeneity is relevant, random-effect meta-regression will be performed.

ETHICS AND DISSEMINATION

The results will be disseminated through peer-reviewed publication and will be presented at a professional conference. Ethical assessment is not required as we will search and assess existing sources of literature.

A RCT to evaluate a totally automated, culturally-adapted telephone counselor for increasing physical activity among physically inactive individuals in China

BACKGROUND

The prevalence of diabetes in China has rapidly increased in recent years. Family history and physical inactivity are known risk factors for developing diabetes. As automated telephone-based communication is recognized as a cost-effective health promoting device, the present study aims at evaluating the efficacy of an automated telephone counselor (TLC-PA-China) for promoting physical activity to the WHO-recommended level among physically inactive family members of diabetes patients.

METHODS

This study employed a parallel, two-group, non-blinded, randomized controlled trial design with equal allocation to the intervention group (TLC-PA-China), and a control group. Voluntary participants with at least one first-degree relative diagnosed with diabetes mellitus were recruited through eight Community Health Centers in Shenzhen, China. The intervention group was requested to use the system once per week during a six-month period. The control group received an information pamphlet about the benefits of regular physical activity.

RESULTS

Two hundred ten eligible participants were randomized to TLC-PA-China (n = 109) or Control (n = 101) groups. Using intention-to-treat analysis, the TLC-PA-China group was significantly more likely to meet the WHO physical activity recommendation than the control (GEE: OR = 6.37, p < 0.001). The number of physically inactive people to intervene upon for one to become active was 2.84 at 3 months and 3.31 at 6 months.

CONCLUSIONS

TLC-PA-China increased physical activity levels among physically inactive adults in China who were at high risk of developing diabetes. This study lays the groundwork for application of behavioral informatics intervention in China.

Women's Heart Health: Knowledge, Beliefs, and Practices of Canadian Physicians

BACKGROUND

Heart disease is a leading cause of morbidity and mortality in women. To date, the majority of knowledge regarding heart disease is based on research conducted in men. As a result, a male-oriented model of heart disease constitutes the basis for diagnostic and therapeutic strategies for both sexes. This article reports findings from the first survey of Canadian physicians to examine their knowledge, beliefs, and practices regarding heart disease in women.

MATERIALS AND METHODS

This cross-sectional survey, adapted from an instrument used in the United States, was undertaken in the spring of 2015. A sample of 504 physicians from a randomly selected sample of online responses was produced.

RESULTS

Overall, physician responses demonstrate a general lack of awareness regarding the prevalence and approaches to the identification of, and treatments for, heart disease in women. In addition, physicians did not provide high ratings of their own effectiveness in supporting female patients to prevent or manage heart disease. The barriers that physicians face and the strategies to support them in improving women's heart health were explored.

CONCLUSIONS

There is a clear need to educate physicians about heart disease in women and its prevention and management. More female-specific research, prevention, and clinical programs will enhance our ability to significantly improve cardiovascular health in Canadian women.

Employees' Expectations of Internet-Based, Workplace Interventions Promoting the Mediterranean Diet: A Qualitative Study

OBJECTIVE

Explore employees' perceptions of ability to follow the Mediterranean diet (MedDiet), preferences for setting goals if asked to follow the MedDiet, and expectations of an Internet-based, workplace MedDiet intervention.

DESIGN

Seven focus groups to guide intervention development.

SETTING

Four workplaces (business/professional services, government branches) in Southwest England.

PARTICIPANTS

Employees (n = 29, 51.7% women), ages 24-58 years.

PHENOMENON OF INTEREST

Ability to follow the MedDiet; preferences for goal-setting if asked to follow the MedDiet; intervention content.

ANALYSIS

Data were analyzed with the use of thematic analysis.

RESULTS

Participants perceived that adhering to some MedDiet recommendations would be challenging and highlighted cost, taste, and cooking skills as adherence barriers. Behavior change preferences included a tailored approach to goal-setting, reviewing goal progress via a website/smartphone app, and receiving expert feedback via an app/website/text/face-to-face session. Desirable features of an Internet-based MedDiet application included recipes, interactivity, nutritional information, shopping tips, cost-saving information, and a companion smartphone app. Engaging in social support was deemed important to facilitate adherence.

CONCLUSIONS AND IMPLICATIONS

An Internet-based, workplace MedDiet intervention should address adherence barriers, utilize a tailored approach to setting and reviewing goals, and activate social support to facilitate adherence. These findings provide insights to planning to promote the MedDiet in non-Mediterranean regions.

An Interactive Multimedia Program to Train Professional Caregivers

An interactive multimedia computer training program on CD-ROM was compared with a videotaped lecture-based training program for professional caregivers of patients with dementia. Both programs promoted use of appropriate communication skills including speaking skills, reacting skills, redirection skills, and use of communication cards for redirection. Professional and paraprofessional caregivers (N = 88) were recruited as participants and randomly assigned to view one of the training programs. In a pretest-posttest design, participants rated caregiver responses in video vignettes of specific caregiving situations. At posttest, those who viewed the interactive program were significantly more likely to: (a) identify the correct responses, (b) intend to use correct strategies, and (c) have increased self-efficacy to use correct strategies, compared to participants who saw the videotaped lecture.

Difference in Effectiveness of Medication Adherence Intervention by Health Literacy Level

CONTEXT

There is little research investigating whether health information technologies, such as interactive voice recognition, are effective ways to deliver information to individuals with lower health literacy.

OBJECTIVE

Determine the extent to which the impact of an interactive voice recognition-based intervention to improve medication adherence appeared to vary by participants' health literacy level.

DESIGN

Promoting Adherence to Improve Effectiveness of Cardiovascular Disease Therapies (PATIENT) was a randomized clinical trial designed to test the impact, compared with usual care, of 2 technology-based interventions that leveraged interactive voice recognition to promote medication adherence. A 14% subset of participants was sent a survey that included questions on health literacy. This exploratory analysis was limited to the 833 individuals who responded to the survey and provided data on health literacy.

MAIN OUTCOME MEASURES

Adherence to statins and/or angiotensin-converting enzyme inhibitors and/or angiotensin II receptor blockers.

RESULTS

Although intervention effects did not differ significantly by level of health literacy, the data were suggestive of differential intervention effects by health literacy level.

CONCLUSIONS

The differences in intervention effects for high vs low health literacy in this exploratory analysis are consistent with the hypothesis that individuals with lower health literacy may derive greater benefit from this type of intervention compared with individuals with higher health literacy. Additional studies are needed to further explore this finding.

Perceptions of clinicians and staff about the use of digital technology in primary care: qualitative interviews prior to implementation of a computer-facilitated 5As intervention

BACKGROUND

Digital health interventions using hybrid delivery models may offer efficient alternatives to traditional behavioral counseling by addressing obstacles of time, resources, and knowledge. Using a computer-facilitated 5As (ask, advise, assess, assist, arrange) model as an example (CF5As), we aimed to identify factors from the perspectives of primary care providers and clinical staff that were likely to influence introduction of digital technology and a CF5As smoking cessation counseling intervention. In the CF5As model, patients self-administer a tablet intervention that provides 5As smoking cessation counseling, produces patient and provider handouts recommending next steps, and is followed by a patient-provider encounter to reinforce key cessation messages, provide assistance, and arrange follow-up.

METHODS

Semi-structured in-person interviews of administrative and clinical staff and primary care providers from three primary care clinics.

RESULTS

Thirty-five interviews were completed (12 administrative staff, ten clinical staff, and 13 primary care providers). Twelve were from an academic internal medicine practice, 12 from a public hospital academic general medicine clinic, and 11 from a public hospital HIV clinic. Most were women (91 %); mean age (SD) was 42 years (11.1). Perceived usefulness of the CF5As focused on its relevance for various health behavior counseling purposes, potential gains in counseling efficiency, confidentiality of data collection, occupying patients while waiting, and serving as a cue to action. Perceived ease of use was viewed to depend on the ability to accommodate: clinic workflow; heavy patient volumes; and patient characterisitics, e.g., low literacy. Social norms potentially affecting implementation included beliefs in the promise/burden of technology, priority of smoking cessation counseling relative to other patient needs, and perception of CF5As as just "one more thing to do" in an overburdened system. The most frequently cited facilitating conditions were staffing levels and smoking cessation resources and training; the most cited hindering factors were visit time constraints and patients' complex health care needs.

CONCLUSIONS

Integrating CF5As and other technology-enhanced behavioral counseling interventions in primary care requires flexibility to accommodate work flow and perceptions of overload in dynamic environments. Identifying factors that promote and hinder CF5As adoption could inform implementation of other CF behavioral health interventions in primary care.

Development and Implementation of an Interactive Text Messaging Campaign to Support Behavior Change in a Childhood Obesity Randomized Controlled Trial

Text messaging is a promising means of intervening on an array of health issues among varied populations, but little has been published about the development of such interventions. The authors describe the development and implementation of an interactive text messaging campaign for parents to support behavior change among children in a childhood obesity randomized controlled trial. The authors invited 160 parents to participate in a text messaging intervention that provided behavior change support in conjunction with health coaching phone calls and mailed materials on behavioral goals. Throughout the 1-year intervention, the authors sent 1-2 text messages per week. The first asked how the child did with a target behavior the day before; parents who replied received an immediate feedback message tailored to their response. The second included a tip about how to work toward a behavioral goal. Baseline surveys indicate that text messaging is a common means of communication for parents, and many are willing to use text messaging to support behavior change for their child. Results at 1 year indicate a high level of engagement with the text messaging intervention, with nearly two thirds responding to 75% or more of the questions they were sent by text.

Impact of gender on patient preferences for technology-based behavioral interventions

Introduction:

Technology-based interventions offer an opportunity to address high-risk behaviors in the emergency department (ED). Prior studies suggest behavioral health strategies are more effective when gender differences are considered. However, the role of gender in ED patient preferences for technology-based interventions has not been examined. The objective was to assess whether patient preferences for technology-based interventions varies by gender.

Methods:

This was a secondary analysis of data from a systematic survey of adult (≥18 years of age), English-speaking patients in a large urban academic ED. Subjects were randomly selected during a purposive sample of shifts. The iPad survey included questions on access to technology, preferences for receiving health information, and demographics. We defined “technology-based” as web, text message, e-mail, social networking, or DVD; “non-technology-based” was defined as in-person, written materials, or landline. We calculated descriptive statistics and used univariate tests to compare men and women. Gender-stratified multivariable logistic regression models were used to examine associations between other demographic factors (age, race, ethnicity, income) and technology-based preferences for information on specific risky behaviors.

Results:

Of 417 participants, 45.1% were male. There were no significant demographic differences between men and women. Women were more likely to use computers (90.8% versus 81.9%; p=0.03), Internet (66.8% versus 59.0%; p=0.03), and social networks (53.3% versus 42.6%; p=0.01). 89% of men and 90% of women preferred technology-based formats for at least type of health information; interest in technology-based for individual health topics did not vary by gender. Concern about confidentiality was the most common barrier to technology-based use for both genders. Multivariate analysis showed that for smoking, depression, drug/alcohol use, and injury prevention, gender modified the relationship between other demographic factors and preference for technology-based health information; e.g., older age decreases interest in technology-based information for smoking cessation in women but not in men (aOR 0.96, 95% CI 0.93-0.99 versus aOR 1.00, 95% CI 0.97-1.03).

Conclusion:

Our findings suggest ED patients' gender may affect technology preferences. Receptivity to technology-based interventions may be a complex interaction between gender and other demographic factors. Considering gender may help target ED patient populations most likely to be receptive to technology-based interventions.

A comparison of live counseling with a web-based lifestyle and medication intervention to reduce coronary heart disease risk: a randomized clinical trial

IMPORTANCE

Most primary care clinicians lack the skills and resources to offer effective lifestyle and medication (L&M) counseling to reduce coronary heart disease (CHD) risk. Thus, effective and feasible CHD prevention programs are needed for typical practice settings.

OBJECTIVE

To assess the effectiveness, acceptability, and cost-effectiveness of a combined L&M intervention to reduce CHD risk offered in counselor-delivered and web-based formats.

DESIGN, SETTING, AND PARTICIPANTS

A comparative effectiveness trial in 5 diverse family medicine practices in North Carolina. Participants were established patients, aged 35 to 79 years, with no known cardiovascular disease, and at moderate to high risk for CHD (10-year Framingham Risk Score [FRS], ≥10%).

INTERVENTIONS

Participants were randomized to counselor-delivered or web-based format, each including 4 intensive and 3 maintenance sessions. After randomization, both formats used a web-based decision aid showing potential CHD risk reduction associated with L&M risk-reducing strategies. Participants chose the risk-reducing strategies they wished to follow.

MAIN OUTCOMES AND MEASURES

The primary outcome was within-group change in FRS at 4-month follow-up. Other measures included standardized assessments of blood pressure, blood lipid levels, lifestyle behaviors, and medication adherence. Acceptability and cost-effectiveness were also assessed. Outcomes were assessed at 4 and 12 months.

RESULTS

Of 2274 screened patients, 385 were randomized (192 counselor; 193 web): mean age, 62 years; 24% African American; and mean FRS, 16.9%. Follow-up at 4 and 12 months included 91% and 87% of the randomized participants, respectively. There was a sustained reduction in FRS at both 4 months (primary outcome) and 12 months for both counselor-based (-2.3% [95% CI, -3.0% to -1.6%] and -1.9% [95% CI, -2.8% to -1.1%], respectively) and web-based groups (-1.5% [95% CI, -2.2% to -0.9%] and -1.7% [95% CI, -2.6% to -0.8%] respectively). At 4 months, the adjusted difference in FRS between groups was -1.0% (95% CI, -1.8% to -0.1%) (P = .03), and at 12 months, it was -0.6% (95% CI, -1.7% to 0.5%) (P = .30). The 12-month costs from the payer perspective were $207 and $110 per person for the counselor- and web-based interventions, respectively.

CONCLUSIONS AND RELEVANCE

Both intervention formats reduced CHD risk through 12-month follow-up. The web format was less expensive.

Designing and implementing a comparative effectiveness study of two strategies for delivering high quality CHD prevention: methods and participant characteristics for the Heart to Health study

BACKGROUND

Although lifestyle and medications are effective for coronary heart disease (CHD) risk reduction, few studies have examined the comparative effectiveness of various strategies for delivering high quality CHD risk reduction. In this paper, we report on the design and baseline characteristics of participants for just such a trial.

METHODS

We conducted a randomized trial of the same lifestyle and medication intervention delivered in two alternate formats: counselor-delivered or web-based. The trial was conducted at 5 diverse practices in a family medicine research network and included men and women age 35-79 who were at high risk of CHD events based on 10-year predicted Framingham risk of ≥10% or a known history of cardiovascular disease. After individual-level randomization, participants in both arms received a decision aid plus four intensive intervention visits and 3 maintenance visits over 12 months. The primary outcome was change in 10-year predicted CHD risk among patients without prior cardiovascular disease. Secondary outcomes, measured among all participants, included changes in CHD risk factors, cost-effectiveness, and acceptability at 4 and 12-month follow-up.

RESULTS

We randomized 489 eligible patients: 389 without and 100 with a known history of cardiovascular disease. Mean age was 62.3. 75% were white, 25% African-American. 45% had a college education. 88% had health insurance. Mean 10-year predicted CHD risk was 16.9%.

CONCLUSION

We have successfully recruited a diverse sample of practices and patients that will provide a rich sample in which to test the comparative effectiveness of two strategies to implement high quality CHD prevention.

The impact of electronic patient portals on patient care: a systematic review of controlled trials

Background

Modern information technology is changing and provides new challenges to health care. The emergence of the Internet and the electronic health record (EHR) has brought new opportunities for patients to play a more active role in his/her care. Although in many countries patients have the right to access their clinical information, access to clinical records electronically is not common. Patient portals consist of provider-tethered applications that allow patients to electronically access health information that are documented and managed by a health care institution. Although patient portals are already being implemented, it is still unclear in which ways these technologies can influence patient care.

Objective

To systematically review the available evidence on the impact of electronic patient portals on patient care.

Methods

A systematic search was conducted using PubMed and other sources to identify controlled experimental or quasi-experimental studies on the impact of patient portals that were published between 1990 and 2011. A total of 1,306 references from all the publication hits were screened, and 13 papers were retrieved for full text analysis.

Results

We identified 5 papers presenting 4 distinct studies. There were no statistically significant changes between intervention and control group in the 2 randomized controlled trials investigating the effect of patient portals on health outcomes. Significant changes in the patient portal group, compared to a control group, could be observed for the following parameters: quicker decrease in office visit rates and slower increase in telephone contacts; increase in number of messages sent; changes of the medication regimen; and better adherence to treatment.

Conclusions

The number of available controlled studies with regard to patient portals is low. Even when patient portals are often discussed as a way to empower patients and improve quality of care, there is insufficient evidence to support this assumption.

Effectiveness of a proactive mail-based alcohol Internet intervention for university students: dismantling the assessment and feedback components in a randomized controlled trial

Background

University students in Sweden routinely receive proactive mail-based alcohol Internet interventions sent from student health services. This intervention provides personalized normative feedback on alcohol consumption with suggestions on how to decrease drinking. Earlier feasibility trials by our group and others have examined effectiveness in simple parallel-groups designs.

Objective

To evaluate the effectiveness of electronic screening and brief intervention, using a randomized controlled trial design that takes account of baseline assessment reactivity (and other possible effects of the research process) due to the similarity between the intervention and assessment content. The design of the study allowed for exploration of the magnitude of the assessment effects per se.

Methods

This trial used a dismantling design and randomly assigned 5227 students to 3 groups: (1) routine practice assessment and feedback, (2) assessment-only without feedback, and (3) neither assessment nor feedback. At baseline all participants were blinded to study participation, with no contact being made with group 3. We approached students 2 months later to participate in a cross-sectional alcohol survey. All interventions were fully automated and did not have any human involvement. All data used in the analysis were based on self-assessment using questionnaires. The participants were unaware that they were participating in a trial and thus were also blinded to which group they were randomly assigned.

Results

Overall, 44.69% (n = 2336) of those targeted for study completed follow-up. Attrition was similar in groups 1 (697/1742, 40.01%) and 2 (737/1742, 42.31% retained) and lower in group 3 (902/1743, 51.75% retained). Intention-to-treat analyses among all participants regardless of their baseline drinking status revealed no differences between groups in all alcohol parameters at the 2-month follow-up. Per-protocol analyses of groups 1 and 2 among those who accepted the email intervention (36.2% of the students who were offered the intervention in group 1 and 37.3% of the students in group2 ) and who were risky drinkers at baseline (60.7% follow-up rate in group 1 and 63.5% in group 2) suggested possible small beneficial effects on weekly consumption attributable to feedback.

Conclusions

This approach to outcome evaluation is highly conservative, and small benefits may follow the actual uptake of feedback intervention in students who are risky drinkers, the precise target group.

Computer-facilitated rapid HIV testing in emergency care settings: provider and patient usability and acceptability

Providers in emergency care settings (ECSs) often face barriers to expanded HIV testing. We undertook formative research to understand the potential utility of a computer tool, "CARE," to facilitate rapid HIV testing in ECSs. Computer tool usability and acceptability were assessed among 35 adult patients, and provider focus groups were held, in two ECSs in Washington State and Maryland. The computer tool was usable by patients of varying computer literacy. Patients appreciated the tool's privacy and lack of judgment and their ability to reflect on HIV risks and create risk reduction plans. Staff voiced concerns regarding ECS-based HIV testing generally, including resources for follow-up of newly diagnosed people. Computer-delivered HIV testing support was acceptable and usable among low-literacy populations in two ECSs. Such tools may help circumvent some practical barriers associated with routine HIV testing in busy settings though linkages to care will still be needed.

Online training in sports concussion for youth sports coaches

The purpose of this study was to evaluate ACTive: Athletic Concussion Training using Interactive Video Education, an interactive e-learning program designed to train community coaches of youth ages 10-18 in effective sports concussion prevention and management practices. Seventy-five youth sports coaches from across the country completed the study over the Internet. Results of a randomized control trial demonstrated significant differences between treatment and control participants on measures of (a) knowledge about sports concussion, management, and prevention; (b) attitudes about the importance of preventing sports concussion; and (c) intention and self-efficacy in sports concussion management and prevention. The results suggest that ACTive is an effective method of training youth sports coaches who are in an important position to reduce risks associated with sports concussion.

Relationship-Relevant and Family-Friendly eHealth: Innovations in Interactive Health Communication Systems

As the reach of the Internet grows, eHealth is fast becoming a major adjunct to traditional delivery of health information and support worldwide. Existing Interactive health communication systems, however, typically target individual users, focus on individual rather than on relational health, and neglect the relational and familial context of individual health issues. Reviewing developments primarily in the United States, this article applies a "marriage and family lens" to examine web-based technologies for health and well-being and suggests innovations to make eHealth both relationship relevant and family friendly. Although recent innovations offer great promise for supporting the relational "fabric" of family life, specific cautions and the need for research on effectiveness are underscored.

A multimedia patient education program on colorectal cancer screening increases knowledge and willingness to consider screening among Hispanic/Latino patients

OBJECTIVE

To test a multimedia patient education program on colorectal cancer (CRC) screening that was designed specifically for the Hispanic/Latino community, and developed with input from community members.

METHODS

A total of 270 Hispanic/Latino adults, age 50-80 years, participated in Spanish for all phases of this pretest-posttest design. Patients were randomly assigned to a version of the multimedia program that opened with either a positive or negative introductory appeal. Structured interviews assessed screening relevant knowledge (anatomy and key terms, screening options, and risk information), past screening behavior, willingness to consider screening options, intention to discuss CRC screening with the doctor, and reactions to the multimedia patient education program.

RESULTS

The multimedia program significantly increased knowledge of anatomy and key terms (e.g., polyp), primary screening options (FOBT, flexible sigmoidoscopy, colonoscopy), and risk information as well as willingness to consider screening (p<.001 for all). No significant differences emerged between positive and negative introductory appeals on these measures, intention to discuss CRC screening with their doctor, or rating the multimedia program.

CONCLUSION

Multimedia tools developed with community input that are designed to present important health messages using graphics and audio can reach Hispanic/Latino adults across literacy levels and ethnic backgrounds. Additional research is needed to determine effects on actual screening behavior.

PRACTICE IMPLICATIONS

Despite promising results for engaging a difficult-to-reach audience, the multimedia program should not be considered a stand-alone intervention or a substitute for communication with physicians. Rather, it is a priming mechanism intended to prepare patients for productive discussions of CRC screening.

Computerized lifestyle intervention in routine primary health care: evaluation of usage on provider and responder levels

OBJECTIVE

The aim of this study was to evaluate the use of a computerized concept for lifestyle intervention in routine primary health care (PHC).

METHODS

Nine PHC units were equipped with computers providing a lifestyle test and tailored printed advice regarding alcohol consumption and physical activity. Patients were referred by staff, and performed the test anonymously. Data were collected over a period of 1 year.

RESULTS

During the study period 3,065 tests were completed, representing 5.7% of the individuals visiting the PHC units during the period. There were great differences between the units in the number of tests performed and in the proportion of patients referred. One-fifth of the respondents scored for hazardous alcohol consumption, and one-fourth reported low levels of physical activity. The majority of respondents found the test easy to perform, and a majority of those referred to the test found referral positive.

CONCLUSION

The computerized test can be used for screening and intervention regarding lifestyle behaviours in PHC. Responders are positive to the test and to referral.

PRACTICE IMPLICATIONS

A more widespread implementation of computerized lifestyle tests could be a beneficial complement to face-to-face interventions in PHC.

Implementation of a computerized alcohol advice concept in routine emergency care

BACKGROUND

There is a growing body of evidence for computer-generated advice for many health behaviours. This study evaluated the implementation of a computerized concept to provide tailored advice on alcohol in a Swedish emergency department (ED).

AIM

The aim was to evaluate the usage of the concept over 12 months: participation rate among the ED population; representativeness of the participants; and participation development over time.

METHODS

The target population was defined as all patients aged 18-69 years given a card from ED triage staff with a request to conduct a computerized test about their alcohol use. After completing the 5-10-min programme, the patient received a printout, containing personalised alcohol habit feedback, as calculated by the computer from the patient's answers. Data for this study were primarily obtained from the computer programme and ED logs.

RESULTS

Forty-one percent of the target population completed the computerized test and received tailored alcohol advice. The number of patients who used the concept showed a slight decreasing trend during the first half of the year, leveling off for the second half of the year.

CONCLUSION

A computerized concept for provision of alcohol advice can be implemented in an ED without unrealistic demands on staff and with limited external support to attain sustainability.

Investigating Hispanic/Latino perceptions about colorectal cancer screening: a community-based approach to effective message design

OBJECTIVE

The Hispanic/Latino population has been documented as having the lowest colorectal cancer (CRC) screening rates in the United States, putting this group at-risk for late-stage presentation of disease. We assessed knowledge, attitudes, and behavior regarding CRC screening to inform the development of messages that promote screening among Hispanic/Latino patients.

METHODS

In-person structured interviews with Spanish-speaking adults age 50-80 at two clinics and a senior center in a Hispanic/Latino community (N=234).

RESULTS

Most (67.1%) participants had no more than an eighth-grade education and 63.3% reported their reading ability as less than "very good." Only 18.4% of participants correctly identified the colon on a diagram; 19.2% correctly described at least one aspect of a polyp. Less than half of the participants perceived themselves as at-risk for CRC, and less than one-third knew about any of the standard screening tests. After hearing descriptions of the screening tests, participants perceived stool cards as easier, safer, less painful, less embarrassing, and less scary than endoscopy (p<.001). Approximately two-thirds of unscreened patients said that screening had never been mentioned or suggested to them; about one-quarter said they did not get screened because they felt fine or were not worried. Over 96% of participants said they would get screened if a doctor suggested it.

CONCLUSION

Assessing knowledge, attitudes, beliefs, and experiences in the community of interest is a promising approach for developing effective targeted health messages.

PRACTICE IMPLICATIONS

Messages to increase CRC screening knowledge and behavior in the Hispanic/Latino community should address risk factors, identify relevant anatomy, explain polyps and their asymptomatic presentation, and clearly describe options.

Who participates in a computer-tailored physical activity program delivered through the Internet? A comparison of participants' and non-participants' characteristics

BACKGROUND

Today, more and more health professionals use the Internet to deliver behavioral change interventions, because of its advantage to reach a wide variety of people at low costs. However, little is known about who is interested in and actually participates in such website-delivered programs. Therefore, the purpose of this manuscript was to examine the characteristics of participants and non-participants (parents recruited through schools) in a computer-tailored physical activity intervention delivered through the Internet.

METHODS

Data was collected in two ways. First, 5706 brochures with a call to participate in a physical activity program, with as key element a website-delivered tailored physical activity advice, were distributed indirectly (through their children) to parents of all pupils in 14 primary and secondary schools in Belgium. Parents were asked to return the reply card mentioning if they wanted to participate or not. Second, characteristics of participating and non-participating parents were collected by distributing 2000 short questionnaires to pupils between 10-18 years of age, in 12 of the 14 schools. Chi-square analysis and binary logistic regressions were used to compare characteristics of those parents who showed interest (i.e. positive response on reply card) or actually participated (completed online assessment) in a website-delivered physical activity intervention with the characteristics of those parents who showed no interest or did not participate.

RESULTS

In total 1730 pupils (87% respondents), completed the short questionnaire concerning their parents' age, occupation (to derive the socio-economic status) and physical activity habits. The results of the binary logistic regression showed that mothers were more likely to show interest (Odds Ratio (OR) = 1.68, p < 0.001) and participate (OR = 2.27, p < 0.005) in the program than fathers. High socioeconomic status (OR = 3.42, p < 0.001) and being employed (OR = 3.03, p < 0.001) were also significant predictors for showing interest but not for participation. Age and physical activity level did neither predict interest nor participation.

CONCLUSION

Both younger and older adults as well as physically active and inactive people participated in our online computer-tailored physical activity program when recruitment was done through schools. However, other health-education programs are still needed to reach all segments of the population equally.

The future of tobacco-control research

Recent epidemiologic data on the stabilization of adult and youth smoking rates underscore the need for vigorous research across the cancer control spectrum on tobacco use interventions. The steady decline in adult rates of smoking has stalled for the first time in 8 years, and certain race, ethnic, and population groups are disproportionately at risk to tobacco-related cancers because of disparities in tobacco use or access to effective interventions. Although substantial progress has been made across levels of basic through applied research, tobacco-control research across the discovery and delivery continuum must be accelerated to further reduce the cancer burden. Following a brief review of the prevalence and trends affecting tobacco use initiation and cessation, we identify and describe four domains of extraordinary research opportunities: genetics and gene-environment interactions, bioinformatics and health informatics, disparities and disproportionate risk, and prevention and treatment. Evolutionary scientific changes, like rapidly advancing technology and emphasis on the paradigm of team science research approaches, provide both a challenge as well as unparalleled opportunities for scientific advancement and public health progress.

Patient and staff perspectives on the use of a computer counseling tool for HIV and sexually transmitted infection risk reduction

PURPOSE

To explore use of an interactive health communication tool--"Computer Assessment and Risk Reduction Education (CARE) for STIs/HIV."

METHODS

This was a mixed method study utilizing participant observation and in-depth interviews with patients (n = 43), and focus groups with staff (5 focus groups, n = 41) from 5 clinics in 3 states (1 Planned Parenthood, 1 Teen, 2 STD, and 1 mobile van clinic). Data were managed using Atlas.ti. Inter-rater reliability of qualitative coding was .90.

RESULTS

Users were 58% nonwhite with mean age 24.7 years (74% < 25). Patients could use CARE with minimal to no assistance. Time for session completion averaged 29.6 minutes. CARE usefulness was rated an average of 8.2 on an ascending utility scale of 0 to 10. Patient themes raised as strengths were novelty, simplicity, confidentiality, personalization, and plan development, increased willingness to be honest, lack of judgment, and a unique opportunity for self-evaluation. Staff themes raised as strengths were enhanced data collection, handout customization, education standardization, behavioral priming, and expansion of services. Patient limitation themes included limited responses and lack of personal touch. Staff limitation themes were selecting users, cost, patient-provider role, privacy, and time for use.

CONCLUSIONS

CARE was well-received and easily usable by most (especially 18-25-year-olds). Patient and staff perceptions support the use of CARE as an adjunct to usual practice and as a method to expand services. Honesty, reduced time constraints, and lack of judgment associated with CARE appeared to enhance self-evaluation, which may prove an important component in moving patients forward in the behavior change process.

Step into Motion: a randomized trial examining the relative efficacy of Internet vs. print-based physical activity interventions

Over two-thirds of Americans access the Internet and therefore, the Internet may be an important channel for reaching the large population of sedentary individuals. The purpose of this paper is to describe the methods for a randomized controlled trial examining the efficacy of an Internet-based physical activity intervention relative to a print intervention that has been shown to be effective in previous trials. Specifically, 249 sedentary participants were randomized to receive one of three interventions: 1) Internet-based motivationally-tailored individualized feedback (Tailored Internet); 2) print-based motivationally-tailored individualized feedback (Tailored Print); or 3) physical activity websites currently available to the public (Standard Internet). Participants completed the 7-Day Physical Activity Recall interview, wore an objective physical activity monitor (i.e., ActiGraph), and participated in a treadmill fitness test at baseline, 6, and 12 months. The sample consisted of mostly women (84.2%) and Caucasian individuals (76.4%) who reported exercising an average of 21 min per week at baseline. This is the first study that we are aware of, that has examined the efficacy of a tailored Internet-based physical activity intervention. This study will have implications for the dissemination of Internet-based physical activity interventions.

Tailored program evaluation: Past, present, future

This paper discusses measurement issues related to the evaluation of computer-tailored health behavior change programs. As the first generation of commercially available tailored products is utilized in health promotion programming, programmers and researchers are becoming aware of the unique challenges that the evaluation of these programs presents. A project is presented that used an online tailored health behavior assessment (HBA) in a worksite setting. Process and outcome evaluation methods are described and include the challenges faced, and strategies proposed and implemented, for meeting them. Implications for future research in tailored program development, implementation, and evaluation are also discussed.

A pilot study of an interactive web site in the workplace for reducing alcohol consumption

An interactive web-site-based intervention for reducing alcohol consumption was pilot tested. Participants were 145 employees of a work site in the Silicon Valley region of California, categorized as low or moderate risk for alcohol problems. All participants were given access to a web site that provided feedback on their levels of stress and use of coping strategies. Participants randomized to the full individualized feedback condition also received individualized feedback about their risk for alcohol-related problems. Some evidence was found for greater alcohol reduction among participants who received full individualized feedback, although due to difficulties in recruiting participants, the sample size was inadequate for evaluating treatment effects on drinking. The results provide preliminary support for using an interactive web site to provide individualized feedback for persons at risk for alcohol problems. However, the low participation rate (2.7%) suggests that such an intervention must address the challenges of recruiting employees through their work site.

Beliefs and attitudes about influenza immunization among parents of children with chronic medical conditions over a two-year period

Influenza vaccination is recommended for children with chronic medical conditions yet is infrequently performed. The reasons for low influenza vaccination rates in this group have not been well studied. We assessed and compared parents of children with chronic medical conditions regarding their beliefs and attitudes about influenza vaccination in 2003 and 2004. Parents of 2- to 13-year-old children with chronic medical conditions from health centers in low-income urban neighborhoods completed a 19-question survey, mailed following the 2002-2003 and 2003-2004 influenza seasons. Parent-reported influenza vaccination rate declined from 2003 (44%) to 2004 (25%). The most important factors related to influenza vaccination status were perceived doctor's recommendation (odds ratio [OR] = 6.0, 95% confidence interval [CI] = 3.7-9.7), parents' belief that the child should be vaccinated (OR = 5.4, 95%CI = 3.3-8.8), relatives' belief that the child should be vaccinated (OR = 1.7, 95%CI = 1.1-2.7), easy access to the doctor's office for a flu shot (OR = 2.4, 95%CI = 1.4-4.2), and receipt of a reminder from the doctor's office (OR = 1.7, 95%CI = 1.1-2.6). In 2004 compared with 2003, fewer parents reported getting a reminder, and fewer believed that their child's doctor recommended flu vaccine. Doctors' recommendation that children with chronic medical conditions should receive an annual influenza vaccine and vaccine availability are important factors that resulted in a higher likelihood of influenza vaccination. Our findings that fewer parents reported receiving reminders and that fewer children were vaccinated in 2004 suggest that sustained improvements in vaccination rates may require continual changes in the format and delivery method of vaccination reminders from physicians.

eHealth promotion: the use of the Internet for health promotion

The use of the Internet for health promotion is explored in this edition including growth trends, general applicability, and evaluation strategies for online interventions. This article examines the range of preliminary studies of eHealth Promotion interventions and their summary results, and reviews potential evaluation tools and their use in online programming. Also assessed is their utility in population-based programming and review-selected implications for the field.

Improving dietary self-monitoring and adherence with hand-held computers: a pilot study

PURPOSE

Innovations in information technology offer new opportunities for creative application of personalized, tailored feedback strategies for improving dietary adherence. We developed and tested a real-time diet-monitoring and feedback system using hand-held computers. The goals were to increase diet self-monitoring, reduce the burden of monitoring food intake, and increase adherence to dietary goals within a clinical trial.

METHODS

Participants were 33 women in the Diet Modification arm of the Women's Health Initiative (WHI). After using focus groups to determine system features, women used the Personal Digital Assistant (PDA)-based system for 1 month and received immediate and weekly tailored feedback. The process and outcomes were evaluated using real-time food records collected through the PDAs; surveys; and self-reported food frequency questionnaires.

RESULTS

Participants significantly increased self-monitoring, improved their attitudes toward self-monitoring, and met their dietary goals more often. Reported total fat intake and percent energy from fat decreased significantly. There was a modest decrease in mean caloric intake.

DISCUSSION

The pilot study findings support the largely untapped potential of hand-held computers for improving diet monitoring and diet adherence, particularly within a clinical trial.

Health behaviors during and after a cancer diagnosis

With improvements in cancer survival rates, more patients with cancer are living longer, and hence, cancer is becoming viewed as a chronic illness requiring long-term management. An important aspect of patient care during and after cancer treatment is patient health behaviors. For example, sequelae from various cancer treatments, such as chemotherapy and radiotherapy (RT), can compromise health in a variety ways, including decreased immune functioning, cardiotoxic effects of chemotherapy and/or RT, and weight gain. In addition, the stress caused by a cancer diagnosis and its treatment can disrupt existing health behaviors or exacerbate unhealthy behaviors. Continued smoking or alcohol use can complicate treatment and increase risk for further malignancy. Furthermore, decreased physical activity and poor nutrition can cause weight gain, which may contribute to secondary health problems such as cardiovascular disease and diabetes. The authors reviewed the extant literature on four key health behaviors among patients with cancer and survivors: healthy diet, reduced tobacco use, reduced alcohol use, and increased physical activity. They described the prevalence of these behaviors, reviewed the effects of interventions designed to alter unhealthy behaviors, and discussed the implications and future directions for this emerging area of research.

A 10-year retrospective of research in new technologies for health communication

The use of new technologies is growing in virtually all areas of health communication, including consumer, patient, and provider education; decision and social support; health promotion; knowledge transfer; and the delivery of services. Many applications have the potential to make major contributions in meeting the needs of an unhealthy and aging population. Key questions confronting health communication research reflect long-standing concerns about effects of new technology on health knowledge, health behavior, health delivery, and health outcomes. A review of the literature provides useful insights about how technology has been used to communicate health messages and their associated outcomes. Focus is placed on effective health communication, lessons learned, and implications for the future. During the next 10 years, the application of new technologies in health communication will be enriched by a tradition that has evolved to reflect a more dynamic connection between health users and providers. Future applications have the potential to provide cost-effective communications tailored to large numbers of individuals and achieve positive health outcomes. Consequently, we should strive to answer research questions about tailoring communication content, the channel used to deliver the message, and evaluation models that are best suited for examining outcomes of multicomponent tailored, technology-based communication.

The information architecture of behavior change websites

The extraordinary growth in Internet use offers researchers important new opportunities to identify and test new ways to deliver effective behavior change programs. The information architecture (IA)—the structure of website information—is an important but often overlooked factor to consider when adapting behavioral strategies developed in office-based settings for Web delivery. Using examples and relevant perspectives from multiple disciplines, we describe a continuum of website IA designs ranging from a matrix design to the tunnel design. The free-form matrix IA design allows users free rein to use multiple hyperlinks to explore available content according to their idiosyncratic interests. The more directive tunnel IA design (commonly used in e-learning courses) guides users step-by-step through a series of Web pages that are arranged in a particular order to improve the chances of achieving a goal that is measurable and consistent. Other IA designs are also discussed, including hierarchical IA and hybrid IA designs. In the hierarchical IA design, program content is arranged in a top-down manner, which helps the user find content of interest. The more complex hybrid IA design incorporates some combination of components that use matrix, tunnel, and/or hierarchical IA designs. Each of these IA designs is discussed in terms of usability, participant engagement, and program tailoring, as well as how they might best be matched with different behavior change goals (using Web-based smoking cessation interventions as examples). Our presentation underscores the role of considering and clearly reporting the use of IA designs when creating effective Web-based interventions. We also encourage the adoption of a multidisciplinary perspective as we move towards a more mature view of Internet intervention research.

A framework for modeling health behavior protocols and their linkage to behavioral theory

With the rise in chronic, behavior-related disease, computerized behavioral protocols (CBPs) that help individuals improve behaviors have the potential to play an increasing role in the future health of society. To be effective and widely used CBPs should be based on accepted behavioral theory. However, designing CBPs while at the same time specifying their linkages to behavioral theory and developing reusable CBP components (interventions) are challenges to developers of CBPs. Having an ontology with which to describe CBPs could help with these issues. As a first step towards creating such an ontology, we modeled PACE-Adolescent, a theory-based behavioral protocol that uses the Stages of Change Model and Social Cognitive Theory, using PROTEGE-2000, an ontology editor and knowledge acquisition system. We created a three-part knowledge model. Two sub-ontologies described behavioral interventions and psychological theories. The third component, implemented using Guideline Interchange Format (GLIF3), provided a way to describe the structure of a protocol and to link intervention resources and groups of actions to elements of psychological theory. Using this framework, we formally described the PACE-Adolescent protocol. Creating knowledge models such as this may lead to improvements in the design and evaluation of computerized health behavior protocols.

Multiple behavioral risk factor interventions in primary care. Summary of research evidence

BACKGROUND

An important barrier to the delivery of health behavior change interventions in primary care settings is the lack of an integrated screening and intervention approach that can cut across multiple risk factors and help clinicians and patients to address these risks in an efficient and productive manner.

METHODS

We review the evidence for interventions that separately address lack of physical activity, an unhealthy diet, obesity, cigarette smoking, and risky/harmful alcohol use, and evidence for interventions that address multiple behavioral risks drawn primarily from the cardiovascular and diabetes literature.

RESULTS

There is evidence for the efficacy of interventions to reduce smoking and risky/harmful alcohol use in unselected patients, and evidence for the efficacy of medium- to high-intensity dietary counseling by specially trained clinicians in high-risk patients. There is fair to good evidence for moderate, sustained weight loss in obese patients receiving high-intensity counseling, but insufficient evidence regarding weight loss interventions in nonobese adults. Evidence for the efficacy of physical activity interventions is limited. Large gaps remain in our knowledge about the efficacy of interventions to address multiple behavioral risk factors in primary care.

CONCLUSIONS

We derive several principles and strategies for delivering behavioral risk factor interventions in primary care from the research literature. These principles can be linked to the "5A's" construct (assess, advise, agree, assist, and arrange-follow up) to provide a unifying conceptual framework for describing, delivering, and evaluating health behavioral counseling interventions in primary healthcare settings. We also provide recommendations for future research.

Interactive behavior change technology. A partial solution to the competing demands of primary care

BACKGROUND

Primary care practices are faced with the challenge of having too much to do in too little time. As a result, behavioral counseling is often overlooked, especially for patients with multiple health behaviors in need of change.

METHODS

This paper describes recent examples of the application of interactive behavior change technologies (IBCTs) to deliver health behavior change counseling before, during, and after the office visit to inform and enhance patient-clinician interactions around these issues. The 5A's framework (assess, advise, agree, assist, arrange follow-up) is used to consider how interactive technology can be used to implement behavior change counseling more consistently.

RESULTS

A variety of IBCTs, including the Internet, clinic-based CD-ROMs, and interactive voice-response telephone calls have been shown to be feasible and potentially valuable adjuncts to clinic-based behavioral counseling. These technologies can both increase the effectiveness of behavioral counseling and extend the reach of these services to patients with barriers to face-to-face interactions.

CONCLUSIONS

If appropriately developed with the context of primary care in mind and integrated as part of a systems approach to intervention, IBCT can be a feasible and appropriate aid for primary care. Recommendations are made for the types of IBCT aids and research that are needed to realize this potential.

Providing a web-based online medical record with electronic communication capabilities to patients with congestive heart failure: randomized trial

Background

It is possible to provide patients with secure access to their medical records using the Internet. Such access may assist patients in the self-management of chronic diseases such as heart failure.

Objective

To assess how a patient-accessible online medical record affects patient care and clinic operations. The SPPARO (System Providing Access to Records Online) software consisted of a web-based electronic medical record, an educational guide, and a messaging system enabling electronic communication between the patient and staff.

Methods

A randomized controlled trial was conducted in a specialty practice for patients with heart failure. Surveys assessing doctor-patient communication, adherence, and health status were conducted at baseline, 6 months, and 1 year. Use of the system, message volume, utilization of clinical services, and mortality were monitored.

Results

One hundred and seven patients were enrolled (54 intervention and 53 controls). At 12 months, the intervention group was not found to be superior in self-efficacy (KCCQ self-efficacy score 91 vs. 85, p=0.08), but was superior in general adherence (MOS compliance score 85 vs. 78, p=0.01). A trend was observed for better satisfaction with doctor-patient communication. The intervention group had more emergency department visits (20 vs. 8, p=0.03), but these visits were not temporally related to use of the online medical record. There were no adverse effects from use of the system.

Conclusions

Providing patients with congestive heart failure access to an online medical record was feasible and improved adherence. An effect on health status could not be demonstrated in this pilot study.

Dietary change, nutrition education and chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a prevalent and serious condition. Nutrition might play a role in COPD prevention and is definitely important in COPD management. There are some indications from epidemiological studies that dietary factors such as ample consumption of fruit and fish may decrease COPD risk. The available evidence is, however, not substantial enough to warrant dietary recommendations for primary prevention of COPD. Substantial evidence does point to the conclusion that, regardless of disease severity, weight loss is related to decreased exercise capacity, health status and mortality as well as to increased morbidity among patients with moderate to severe COPD. Current nutritional support strategies have primarily focussed on treatment of severely underweight and disabled patients. In an in-patient setting or when incorporated in a pulmonary rehabilitation programme, nutritional support has proved effective in inducing weight gain and related functional improvements. However, such interventions are only feasible for a selected group of patients and are very laborious. Therefore, opportunities for dietary and nutrition interventions in COPD management should be explored, aiming at early detection, prevention and early treatment of involuntary weight loss. This means expanding the target group to include COPD out-patients and primary care patients before they have become underweight, and putting more emphasis on dietary change than on medically prescribed supplementation. Successful intervention assumes (voluntary) adjustment of dietary behaviour, and health professionals may play an essential role in encouraging patients to make and maintain these changes. Achieving dietary change among COPD patients may require a combination of diet counselling and self-management. A model for such a combination is presented.

Eliminating disparities: empowering health promotion within preventive medicine

The estimated 800,000 U.S. deaths in 1990 related to behavioral decisions challenge physicians to better assist behavioral change through expanded health promotion activities. Based on the format guidelines of this special issue, this brief paper first examines the current and optimal roles of health promotion within Preventive Medicine, including five physician roles for improving modifiable public health-risk behavior burdens: (1) preventive services clinician, (2) health promotion researcher, (3) educator-communicator, (4) systems manager, and (5) health promotion advocate. After presenting a new vision statement, this paper proceeds to discuss the opportunities and barriers, including system, clinician-office, and patient factors, to attaining this new vision of empowering health promotion within Preventive Medicine. Finally, all physicians are invited to engage in a threefold strategic plan for change through at least one of five action items: (1) health promotion advocacy, (2) health promotion research, (3) public communication, (4) protocol dissemination and implementation, and (5) Preventive Medicine training.

Personal relationships with an intelligent interactive telephone health behavior advisor system: a multimethod study using surveys and ethnographic interviews

The burgeoning of consumer health informatics and virtual health care can help people improve their health. However, little is known about individuals' reactions to such systems. We conducted an evaluation of the telephone-linked care (TLC) system, a computer-based telecommunications system, that functions as an at home monitor, educator, and counselor for patients with chronic health conditions. Our multimethod assessment of individuals' reactions to using TLC included both quantitative and qualitative methods. Ethnographic in-depth open-ended interviews indicated more subtle and surprising reactions to TLC than the overall positive responses from surveys: individuals formed personal relationships with this technology. This relationship formation suggests that TLC designers may have been successful in their attempts to emulate a conversation with a human being. Our study adds to evidence that technology can serve as a projective device for peoples' values and psychological issues. Both designers and users project values and goals onto computer-based technologies and take on different identities through it. Different groups of users, therefore, may see the same technology differently. People also form relationships with technologies, as they did with TLC. These findings, as well as implications for system design and health outcomes, need to be explored in additional studies.

Participant reactions to a computerized telephone system for nutrition and exercise counseling

This paper reports on an evaluation of the reactions of participants in a computer-controlled telephone conversation system (telephone-linked care, TLC) designed to offer nutrition and exercise counseling. After 6 months in the study, subjects were asked a series of questions about their opinions of the TLC system, including overall satisfaction and the system's helpfulness. One hundred and ninety individuals completed the attitude survey. On a scale of 0-100, respondents rated the overall satisfaction and helpfulness of the system at 63.6 and 62.3. Subjects using the nutrition counseling version of TLC rated it significantly higher on satisfaction (73.0 versus 52.4) and helpfulness (70.3 versus 53.7) than did subjects using the exercise version. Satisfaction and helpfulness were correlated with perceived usability, amount of contact, realism, and credibility (P < 0.01). Multivariate analyses showed that treatment group and number of calls made accounted for the greatest amount of variance in ratings of satisfaction and helpfulness. The findings suggest that the amount of contact with this technology, reflected by the number of calls, and the treatment group, nutrition or exercise, were significant predictors of reported satisfaction and perceived helpfulness of the system.

Program participation and physical activity maintenance after cardiac rehabilitation

This study examined exercise maintenance among patients after completing cardiac rehabilitation. Subjects were men and women who had completed a Phase II Cardiac Rehabilitation Program approximately 12 months previously. Subjects were classified according to whether they had (a) never participated in a Phase III program (G-I) (N = 37), (b) enrolled and completed a Phase III program (G-II) (N = 30), or (c) were currently enrolled in a Phase III maintenance program (G-III) (N = 33). Subjects were significantly more likely to be participating in regular exercise if they had participated in a Phase III program (p < .05). Individuals in G-II and G-III engaged in more minutes of physical activity per week and were more likely to meet recommended levels of physical activity compared to G-1 subjects. G-1 individuals who had longer Phase II programs were more likely to maintain their exercise habits following graduation (p < .05). Results suggest that Phase III maintenance programs and longer Phase II participation improved exercise maintenance following rehabilitation.

The patient-computer interview: a neglected tool that can aid the clinician

In this article, I (1) review the process of interviewing patients by computer, (2) summarize computer-interviewing work done in 1968, (3) address the weaknesses of collecting information with the traditional history-taking methods or paper questionnaires, (4) discuss commercial software designed for computer interviewing, and (5) focus on the strengths and weaknesses of interviewing patients with a computer. The strengths of this process compared with traditional interviewing are that computer interviewing allows the physician to gather more data; gives the patient more time to complete an interview; uncovers more sensitive information; provides more adaptability to non-English-speaking patients, patients with hearing impairment, or patients who are illiterate; and provides structured information for research. The weaknesses of computer interviewing are that it generates false-positive responses, is not accepted by a minority of patients, is unable to detect nonverbal behavior, and requires changes in work flow. With the advent of an electronic medical record and the financial rewards for comprehensive history recording, the gathering of history and documentation from patients is increasingly important and favors adaptation to computer interviewing.
