Diagnostic uncertainty and decision-making in home-based primary care: A qualitative study of antibiotic prescribing.

BACKGROUND: Evaluating infection in home-based primary care is challenging, and these challenges may impact antibiotic prescribing. A refined understanding of antibiotic decision-making in this setting can inform strategies to promote antibiotic stewardship. This study investigated antibiotic decision-making by exploring the perspectives of clinicians in home-based primary care. METHODS: Clinicians from the Department of Veterans Affairs Home-Based Primary Care Program were recruited. Semi-structured interviews were conducted from June 2022 through September 2022 using a discussion guide. Transcripts were analyzed using grounded theory. The constant comparative method was used to develop a coding structure and to identify themes. RESULTS: Theoretical saturation was reached after 22 clinicians (physicians, n = 7; physician assistants, n = 2, advanced practice registered nurses, n = 13) from 19 programs were interviewed. Mean age was 48.5 ± 9.3 years, 91% were female, and 59% had ≥6 years of experience in home-based primary care. Participants reported uncertainty about the diagnosis of infection due to the characteristics of homebound patients (atypical presentations of disease, presence of multiple chronic conditions, presence of cognitive impairment) and the challenges of delivering medical care in the home (limited access to diagnostic testing, suboptimal quality of microbiological specimens, barriers to establishing remote access to the electronic health record). When faced with diagnostic uncertainty about infection, participants described many factors that influenced the decision to prescribe antibiotics, including those that promoted prescribing (desire to avoid hospitalization, pressure from caregivers, unreliable plans for follow-up) and those that inhibited prescribing (perceptions of antibiotic-associated harms, willingness to trial non-pharmacological interventions first, presence of caregivers who were trusted by clinicians to monitor symptoms). CONCLUSIONS: Clinicians face the difficult task of balancing diagnostic uncertainty with many competing considerations during the treatment of infection in home-based primary care. Recognizing these issues provides insight into strategies to promote antibiotic stewardship in home care settings.

Effect of Computer-Tailored Print Feedback, Motivational Interviewing, and Motivational Enhancement Therapy on Engagement in Advance Care Planning: A Randomized Clinical Trial.

Importance: There is a tension between clinician-led approaches to engagement in advance care planning (ACP), which are effective but resource-intensive, and self-administered tools, which are more easily disseminated but rely on ability and willingness to complete. Objective: To examine the efficacy of computer-tailored print feedback (CTPF), motivational interviewing (MI), and motivational enhancement therapy (MET) on completion of a set of ACP activities, each as compared with usual care. Design, Setting, and Participants: This randomized clinical trial was conducted from October 2017 to December 2020 via telephone contact with primary care patients at a single VA facility; 483 veterans aged 55 years or older were randomly selected from a list of patients with a primary care visit in the prior 12 months, with oversampling of women and people from minoritized racial and ethnic groups. Statistical analysis was performed from January to June 2022. Interventions: Mailed CTPF generated in response to a brief telephone assessment of readiness to engage in and attitudes toward ACP; MI, an interview exploring ambivalence to change and developing a change plan; and MET, MI plus print feedback, delivered by telephone at baseline, 2, and 4 months. Main Outcome and Measures: Self-reported completion of 4 ACP activities: communicating about views on quality vs quantity of life, assignment of a health care agent, completion of a living will, and submitting documents for inclusion in the electronic health record at 6 months. Results: The study included 483 persons, mean (SD) age 68.3 (8.0) years, 18.2% women and 31.1% who were people from minoritized racial and ethnic groups. Adjusting for age, education, race, gender, and baseline stage of change for each ACP, predicted probabilities for completing the ACP activities were: usual care 5.7% (95% CI, 2.8%-11.1%) for usual care, 17.7% (95% CI, 11.8%-25.9%; P = .003) for MET, 15.8% (95% CI, 10.2%-23.6%; P = .01) for MI, P = .01, and 10.0% (95% CI, 5.9%-16.7%; P = .18) for CTPF. Conclusions and Relevance: This randomized clinical trial found that a series of 3 MI and MET counseling sessions significantly increased the proportion of middle-aged and older veterans completing a set of ACP activities, while print feedback did not. These findings suggest the importance of clinical interaction for ACP engagement. Trial Registration: ClinicalTrials.gov Identifier: NCT03103828.

Effect of the STAMP (Sharing and Talking About My Preferences) Intervention on Completing Multiple Advance Care Planning Activities in Ambulatory Care : A Cluster Randomized Controlled Trial.

BACKGROUND: Interventions with the potential for broad reach in ambulatory settings are necessary to achieve a life course approach to advance care planning. OBJECTIVE: To examine the effect of a computer-tailored, behavioral health model-based intervention on the engagement of adults in advance care planning recruited from ambulatory care settings. DESIGN: Cluster randomized controlled trial with participant-level analysis. (ClinicalTrials.gov: NCT03137459). SETTING: 10 pairs of primary and selected specialty care practices matched on patient sociodemographic information. PARTICIPANTS: English-speaking adults aged 55 years or older; 454 adults at practices randomly assigned to usual care and 455 at practices randomly assigned to intervention. INTERVENTION: Brief telephone or web-based assessment generating a mailed, individually tailored feedback report with a stage-matched brochure at baseline, 2 months, and 4 months. MEASUREMENTS: The primary outcome was completion of the following 4 advance care planning activities at 6 months: identifying and communicating with a trusted person about views on quality versus quantity of life, assignment of a health care agent, completion of a living will, and ensuring that the documents are in the medical record-assessed by a blinded interviewer. Secondary outcomes were completion of individual advance care planning activities. RESULTS: Participants were 64% women and 76% White. The mean age was 68.3 years (SD, 8.3). The predicted probability of completing all advance care planning activities in usual care sites was 8.2% (95% CI, 4.9% to 11.4%) versus 14.1% (CI, 11.0% to 17.2%) in intervention sites (adjusted risk difference, 5.2 percentage points [CI, 1.6 to 8.8 percentage points]). Prespecified subgroup analysis found no statistically significant interactions between the intervention and age, education, or race. LIMITATIONS: The study was done in a single region and excluded non-English speaking participants. No information was collected about nonparticipants. CONCLUSION: A brief, easily delivered, tailored print intervention increased participation in advance care planning in ambulatory care settings.

Diffusing capacity in normal-for-age spirometry and spirometric impairments, using reference equations from the global lung function initiative.

BACKGROUND: Reference equations from the Global Lung Function Initiative (GLI) are now available for both spirometry and diffusion. However, respiratory phenotypes defined by GLI-based measures of diffusion have not yet been evaluated in GLI-based normal-for-age spirometry or spirometric impairments. METHODS: We evaluated cross-sectional data from 2100 Caucasians, aged 40-85 years. GLI-based spirometric categories included normal-for-age and the impairments of restrictive-pattern and three-level severity of airflow-obstruction (mild, moderate, severe). GLI-based diffusion included diffusing capacity of the lung for carbon monoxide (DLCO) and measured components of alveolar volume (VA) and transfer coefficient (KCO): DLCO = [VA]x[KCO]. Using multivariable regression models, adjusted odds ratios (adjORs) for DLCO, VA, and KCO < lower limit of normal (LLN) were calculated for spirometric impairments, relative to normal-for-age spirometry. RESULTS: Relative to normal-for-age spirometry, the restrictive-pattern increased the adjORs (95% confidence intervals) for DLCO and VA < LLN-4.61 (3.62, 5.85) and 15.53 (11.8, 20.4), respectively, but not for KCO < LLN-1.02 (0.79, 1.33). Also relative to normal-for-age spirometry, airflow-obstruction from mild to severe increased the adjORs for DLCO < LLN-from 1.22 (0.80, 1.86) to 6.63 (4.91, 8.95), for VA < LLN-from 1.37 (0.85, 2.18) to 7.01 (5.20, 9.43), and for KCO < LLN-from 2.04 (1.33, 3.14) to 3.03 (2.29, 3.99). Notably, in normal-for-age spirometry, 34.5%, 19.7%, and 25.3% of participants had DLCO, VA, or KCO < LLN, respectively. CONCLUSION: Abnormal diffusion is most prevalent in spirometric impairments but also occurs in normal-for-age spirometry. These results further inform the respiratory phenotypes of GLI-based spirometric categories and, in turn, the spirometric evaluation of respiratory disease.

Optimizing Clock Drawing Scoring Criteria: Development of the West Haven-Yale Clock Drawing Test.

BACKGROUND/OBJECTIVES: The Clock Drawing Test (CDT) is a widely used measure, which has been included as a recommended cognitive screen for driving evaluations. This study aimed to develop an optimized scoring method-the West Haven-Yale CDT (WHY-CDT)-based on the scoring methods of Freund and Royall's CLOX, the latter of which is significantly associated with executive control functions. DESIGN: Retrospective cohort study. SETTING: Greater New Haven, Connecticut, area. PARTICIPANTS: A total of 237 adults, aged 70 years and older, who had a current driver's license and drove at least once a month. MEASUREMENTS: Clock drawings were independently scored using both scoring systems, as well as a qualitative-based 5-point gestalt score. Interrater reliability was calculated using Light's κ for dichotomous variables and intraclass correlations for continuous variables. A categorical principal component analysis was conducted to determine which items from the Freund and Royall scoring systems should be retained in the modified system, with the Kuder-Richardson test used to assess internal consistency (reliability). RESULTS: The majority of the quantitative scoring items had moderate to almost perfect interrater reliability, with excellent interrater reliability for the qualitative gestalt score. The final scoring method retained seven items from the Freund and Royall versions, of which over 85% were from the latter. Internal consistency was fair to acceptable for the WHY-CDT's two dichotomously scored subscales, but poor for both the Freund and Royall scoring methods. CONCLUSIONS: The WHY-CDT is a simple scoring method that combines elements of the Freund and Royall methods, as well as an overall gestalt score, and has strong interrater reliability. Future directions for use of this modified system are discussed. J Am Geriatr Soc 67:2129-2133, 2019.

Feasibility of Delivering a Tailored Intervention for Advance Care Planning in Primary Care Practice.

BACKGROUND/OBJECTIVES: To determine the feasibility of conducting a cluster randomized controlled trial providing individualized feedback reports to increase advance care planning (ACP) engagement in the primary care setting. DESIGN: Pilot cluster randomized controlled trial. SETTING: Two primary care practices selected for geographic colocation. PARTICIPANTS: Adults aged 55 years and older. INTERVENTION: Brief assessment of readiness to engage in (stage of change for) three ACP behaviors (healthcare agent assignment, communication with agent about quality vs quantity of life, and living will completion) generating an individualized feedback report, plus a stage-matched brochure. MEASURES: Patient recruitment and retention, intervention delivery, baseline characteristics, and stage of change movement. RESULTS: Recruitment rates differed by practice. Several baseline sociodemographic characteristics differed between the 38 intervention and 41 control participants, including employment status, education, and communication with healthcare agent. Feedback was successfully delivered to all intervention participants, and over 90% of participants completed a 2-month follow-up. More intervention participants demonstrated progression in readiness than did control participants, without testing for statistical significance. CONCLUSIONS: This pilot demonstrates opportunities and challenges of performing a clustered randomized controlled trial in primary care practices. Differences in the two practice populations highlight the challenges of matching sites. There was a signal for behavior change in the intervention group. J Am Geriatr Soc 67:1917-1921, 2019.

Diagnosing and Treating Sleep Apnea in Patients With Acute Cerebrovascular Disease.

Background Obstructive sleep apnea ( OSA ) is common among patients with acute ischemic stroke and transient ischemic attack. We evaluated whether continuous positive airway pressure for OSA among patients with recent ischemic stroke or transient ischemic attack improved clinical outcomes. Methods and Results This randomized controlled trial among patients with ischemic stroke/transient ischemic attack compared 2 strategies (standard or enhanced) for the diagnosis and treatment of OSA versus usual care over 1 year. Primary outcomes were National Institutes of Health Stroke Scale and modified Rankin Scale scores. Among 252 patients (84, control; 86, standard; 82, enhanced), OSA prevalence was as follows: control, 69%; standard, 74%; and enhanced, 80%. Continuous positive airway pressure use occurred on average 50% of nights and was similar among standard (3.9±2.1 mean hours/nights used) and enhanced (4.3±2.4 hours/nights used; P=0.46) patients. In intention-to-treat analyses, changes in National Institutes of Health Stroke Scale and modified Rankin Scale scores were similar across groups. In as-treated analyses among patients with OSA, increasing continuous positive airway pressure use was associated with improved National Institutes of Health Stroke Scale score (no/poor, -0.6±2.9; some, -0.9±1.4; good, -0.3±1.0; P=0.0064) and improved modified Rankin Scale score (no/poor, -0.3±1.5; some, -0.4±1.0; good, -0.9±1.2; P=0.0237). In shift analyses among patients with OSA, 59% of intervention patients had best neurological symptom severity (National Institutes of Health Stroke Scale score, 0-1) versus 38% of controls ( P=0.038); absolute risk reduction was 21% (number needed to treat, 4.8). Conclusions Although changes in neurological functioning and functional status were similar across the groups in the intention-to-treat analyses, continuous positive airway pressure use was associated with improved neurological functioning among patients with acute ischemic stroke/transient ischemic attack with OSA .

Patient and Caregiver Perspectives on Managing Multiple Health Conditions.

OBJECTIVES: To explore patient and caregiver experiences, preferences, and attitudes toward the provision and receipt of caregiving assistance with medical tasks. DESIGN: Qualitative study consisting of in-depth interviews with 20 patient-caregiver dyads. SETTING: Community and academic-affiliated primary care clinics. PARTICIPANTS: Individuals aged 65 or older with 2 or more health conditions and their family caregivers (n=20 patient-caregiver dyads). MEASUREMENTS: Open-ended questions were asked about the tasks that the patient and caregiver performed to manage the patient's health conditions; questions were designed to elicit participant reactions and attitudes toward the help they provided or received. Transcripts were analyzed using the constant comparative method. RESULTS: Participant preferences and attitudes toward the receipt and provision of disease management tasks were highly personal. Participant responses clustered into 2 caregiving typologies: supportive caregiving relationships and conflicted caregiving relationships. Supportive relationships were characterized by patient-caregiver agreement about caregiver level of involvement, agreement about one another's competency to perform disease-related tasks, mutual understanding, collaborative decision-making and disease management, and use of family and formal caregiving. Conflicted relationships were characterized by disagreement about caregiver level of involvement, disagreement about one another's competency to perform disease management tasks, underappreciation of one another's experiences, disagreement over decision-making and disease management, and use of formal caregiving. CONCLUSIONS: The views that patient-caregiver dyads expressed in this study illustrate the varied preferences and attitudes toward caregiving assistance with multiple health conditions. These findings support a dyadic approach to evaluating and addressing patient and caregiver needs and attitudes toward provision of assistance.

Increasing engagement in advance care planning using a behaviour change model: study protocol for the STAMP randomised controlled trials.

INTRODUCTION: Advance care planning (ACP) is a key component of high-quality end-of-life care but is underused. Interventions based on models of behaviour change may fill an important gap in available programmes to increase ACP engagement. Such interventions are designed for broad outreach and flexibility in delivery. The purpose of the Sharing and Talking about My Preferences study is to examine the efficacy of three behaviour change approaches to increasing ACP engagement through two related randomised controlled trials being conducted in different settings (Veterans Affairs (VA) medical centre and community). METHODS AND ANALYSIS: Eligible participants are 55 years or older. Participants in the community are being recruited in person in primary care and specialty outpatient practices and senior living sites, and participants in the VA are recruited by telephone. In the community, randomisation is at the level of the practice or site, with all persons at a given practice/site receiving either computer-tailored feedback with a behaviour stage-matched brochure (computer-tailored intervention (CTI)) or usual care. At the VA, randomisation is at the level of the participant and is stratified by the number of ACP behaviours completed at baseline. Participants are randomised to one of four groups: CTI, motivational interviewing, motivational enhancement therapy or usual care. The primary outcome is completion of four key ACP behaviours: identification of a surrogate decision maker, communication about goals, completing advance directives and ensuring documents are in the medical record. Analysis will be conducted using mixed effects models, taking into account the clustered randomisation for the community study. ETHICS AND RANDOMISATION: The studies have been approved by the appropriate Institutional Review Boards and are being overseen by a Safety Monitoring Committee. The results of these studies will be disseminated to academic audiences and leadership in in the community and VA sites. TRIAL REGISTRATION NUMBERS: NCT03137459 and NCT03103828.

Spirometry, Static Lung Volumes, and Diffusing Capacity.

BACKGROUND: Spirometric Z-scores from the Global Lung Initiative (GLI) rigorously account for age-related changes in lung function and are thus age-appropriate when establishing spirometric impairments, including a restrictive pattern and air-flow obstruction. However, GLI-defined spirometric impairments have not yet been evaluated regarding associations with static lung volumes (total lung capacity [TLC], functional residual capacity [FRC], and residual volume [RV]) and gas exchange (diffusing capacity). METHODS: We performed a retrospective review of pulmonary function tests in subjects ≥40 y old (mean age 64.6 y), including pre-bronchodilator measures for: spirometry (n = 2,586), static lung volumes by helium dilution with inspiratory capacity maneuver (n = 2,586), and hemoglobin-adjusted single-breath diffusing capacity (n = 2,508). Using multivariable linear regression, adjusted least-squares means (adjLSMeans) were calculated for TLC, FRC, RV, and hemoglobin-adjusted single-breath diffusing capacity. The adjLSMeans were expressed with and without height-cubed standardization and stratified by GLI-defined spirometry, including normal (n = 1,251), restrictive pattern (n = 663), and air-flow obstruction (mild, [n = 128]; moderate, [n = 150]; and severe, [n = 394]). RESULTS: Relative to normal spirometry, restrictive-pattern had lower adjLSMeans for TLC, FRC, RV, and hemoglobin-adjusted single-breath diffusing capacity (P ≤ .001). Conversely, relative to normal spirometry, mild, moderate, and severe air-flow obstruction had higher adjLSMeans for FRC and RV (P < .001). However, only mild and moderate air-flow obstruction had higher adjLSMeans for TLC (P < .001), while only moderate and severe air-flow obstruction had higher adjLSMeans for RV/TLC (P < .001) and lower adjLSMeans for hemoglobin-adjusted single-breath diffusing capacity (P < .001). Notably, TLC (calculated as FRC + inspiratory capacity) was not increased in severe air-flow obstruction (P ≥ .11) because inspiratory capacity decreased with increasing air-flow obstruction (P < .001), thus opposing the increased FRC (P < .001). Finally, P values were similar whether adjLSMeans were height-cubed standardized. CONCLUSIONS: A GLI-defined spirometric restrictive pattern is strongly associated with a restrictive ventilatory defect (decreased TLC, FRC, and RV), while GLI-defined spirometric air-flow obstruction is strongly associated with hyperinflation (increased FRC) and air trapping (increased RV and RV/TLC). Both spirometric impairments were strongly associated with impaired gas exchange (decreased hemoglobin-adjusted single-breath diffusing capacity).

Engagement in Advance Care Planning and Surrogates' Knowledge of Patients' Treatment Goals.

OBJECTIVES: A key objective of advance care planning (ACP) is improving surrogates' knowledge of patients' treatment goals. Little is known about whether ACP outside of a trial accomplishes this. The objective was to examine patient and surrogate reports of ACP engagement and associations with surrogate knowledge of goals. DESIGN: Cohort study SETTING: Primary care in a Veterans Affairs Medical Center. PARTICIPANTS: 350 community-dwelling veterans age ≥55 years and the individual they would choose to make medical decisions on their behalf, interviewed separately. MEASUREMENTS: Treatment goals were assessed by veterans' ratings of 3 health states: severe physical disability, cognitive disability, and pain, as an acceptable or unacceptable result of treatment for severe illness. Surrogates had knowledge if they correctly predicted all 3 responses. Veterans and surrogates were asked about living will and health care proxy completion and communication about life-sustaining treatment and quality versus quantity of life (QOL). RESULTS: Over 40% of dyads agreed that the veteran had not completed a living will or health care proxy and that there was no QOL communication. For each activity, sizeable proportions (18-34%) disagreed about participation. In dyads who agreed QOL communication had occurred, 30% of surrogates had knowledge, compared to 21% in dyads who agreed communication had not occurred and 15% in dyads who disagreed (P = .01). This relationship persisted in multivariable analysis. Agreement about other ACP activities was not associated with knowledge. CONCLUSION: Disagreement about ACP participation was common. Agreement about communication regarding QOL was modestly associated with surrogate knowledge of treatment goals. Eliciting surrogates' perspectives is critical to ACP. Even dyads who agree about participation may need additional support for successful engagement.

A Dyadic Perspective on Engagement in Advance Care Planning.

OBJECTIVES: To understand the perspectives of both patients and the person who would make medical decisions for them if they were unable (surrogates) on their participation in advance care planning (ACP). DESIGN: Qualitative cross-sectional study. SETTING: Community. PARTICIPANTS: Thirty-one veterans age 55 years and older and their surrogates. MEASUREMENTS: In interviews conducted with both the veteran and surrogate, they were asked to discuss their participation in four ACP activities: communication about life-sustaining treatment, communication about views on quality of life, completion of a living will, and appointment of a healthcare proxy. They were asked about barriers to and facilitators of ACP engagement. When they did not agree about engagement, they each provided their perspective on what they believed had or had not occurred. RESULTS: Many of the same barriers to and facilitators of engagement were discussed by both patients and surrogates. These included difficulty thinking about dying, differences in values, and experiences with others that demonstrated the ability of ACP to decrease burden or avoid conflict. Reasons for disagreements in perceptions about whether communication had occurred included surrogates' need for more detailed information, surrogates' lack of readiness to hear what the patient was saying, and surrogates' reliance on what they know about the patient. For some dyads, participation in the study prompted additional communication, resulting in a better shared understanding of ACP engagement. CONCLUSION: Surrogates can both impede and facilitate engagement in ACP, and they can hold different perceptions from patients regarding this engagement. Efforts to promote ACP may be most successful if they assess and address both patients' and surrogates' attitudes and help to facilitate clear communication between them.

Development of Personalized Health Messages to Promote Engagement in Advance Care Planning.

OBJECTIVES: To develop and test the acceptability of personalized intervention materials to promote advance care planning (ACP) based on the Transtheoretical Model (TTM), in which readiness to change is a critical organizing construct. DESIGN: Development study creating an expert system delivering TTM-personalized feedback reports and stage-matched brochures with more-general information on ACP and modifications based on participant reviews. SETTING: Senior centers. PARTICIPANTS: Community-living persons aged 65 and older (N = 77). MEASUREMENTS: Participant ratings of length, attractiveness, and trustworthiness of and reactions to reports and brochures. RESULTS: The expert system assessed participants' readiness to engage in each of four ACP behaviors: completion of a living will, naming a health care proxy, communication with loved ones about quality vs quantity of life, and communication with clinicians about quality vs quantity of life. The system also assessed pros and cons of engagement and values and beliefs that influence engagement. The system provided individualized feedback based on the assessment, with brochures providing additional general information. Initial participant review indicating unacceptable length led to revision of feedback reports from full-sentence paragraph format to bulleted format. After review, the majority of participants rated the materials as easy to read, trustworthy, providing new information, making them more comfortable reading about ACP, and increasing interest in participating in ACP. CONCLUSION: Older adults found an expert system individualized feedback report and accompanying brochure to promote ACP engagement to highly acceptable and engaging. Additional research is necessary to examine the effects of these materials on behavior change.

Age-Related Differences in Sleep-Wake Symptoms of Adults Undergoing Polysomnography.

OBJECTIVES: To evaluate age-related differences in sleep-wake symptoms. DESIGN: Cross-sectional. SETTING: Technologist-attended, laboratory-based polysomnography (PSG). PARTICIPANTS: Community-dwelling adults aged 20 to 89 (N = 201): 52 aged 18 to 39, 72 aged 40 to 59, and 77 aged 60 and older. MEASUREMENTS: Medical burden (Charlson Comorbidity Index, medications, health status), PSG-defined sleep disorders (sleep-disordered breathing (SDB), sleep-associated hypoxemia, periodic limb movements in sleep (PLMS)), sleep-wake symptoms (Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), fatigue (Facit-F Scale)). RESULTS: Medical burden increased significantly with age (Charlson Comorbidity Index and number of medications, P < .001; health status, P = .005). Severity of sleep disorders also increased significantly with age (SDB and hypoxemia, P < .001; PLMS, P = .008). Conversely, sleep-wake symptoms decreased with age (daytime drowsiness (ESS ≥ 10), P = .02; insomnia (ISI ≥ 8), P = .04; fatigue, P < .001). In adjusted models, a 1-year increase in age was significantly associated with a 4% decrease in the odds of having daytime drowsiness (odds ratio (OR) = 0.96, 95% confidence interval (CI) = 0.93-0.98). Similarly, but only in those with mild SDB, a 1-year increase in age was significantly associated with a 5% decrease in the odds of having insomnia (OR = 0.95, 95% CI = 0.92-0.99). CONCLUSION: Older age was characterized by less-severe sleep-wake symptoms (daytime drowsiness, insomnia, fatigue), despite an age-related increase in disease severity (medical burden, sleep disorders). Because the increase in disease severity included well-established risk factors for having sleep-wake symptoms, the age-related decrease in sleep-wake symptoms may reflect a decrease in symptom awareness.

Sleep disturbances and driving practices of older drivers.

OBJECTIVES: To evaluate the associations between sleep disturbances and driving practices, including driving cessation and trajectories of daily driving mileage (change over time), in older drivers. DESIGN: Longitudinal. SETTING: New Haven, Connecticut. PARTICIPANTS: Four hundred thirty older drivers, mean age 78.5, recruited from clinic and community sites. MEASUREMENTS: Baseline measures included medical history, daily driving mileage, Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), and Sleep Apnea Clinical Score (SACS). Longitudinal outcomes included at least one episode of driving cessation and trajectories of miles driven per day, as recorded every 6 months over 2 years. RESULTS: At baseline, participants drove an average of 22.2 miles per day; 26.0% (112/430) had insomnia (ISI ≥ 8), 19.3% (83/430) had daytime drowsiness (ESS ≥ 10), and 19.9% (84/422) had high sleep apnea risk (SACS > 15). The sleep-based predictors of insomnia (risk ratio (RR) = 1.20, 95% confidence interval (CI) = 0.65-2.20), daytime drowsiness (RR = 0.94, 95% CI = 0.46-1.95), and high sleep apnea risk (RR = 0.62, 95% CI = 0.27-1.42) did not confer a significantly greater risk of driving cessation. Insomnia was the only sleep-based predictor that conferred a significant change in driving mileage, yielding an average decrease of 4.5 miles per day over 2 years (P = .01). In the insomnia model, covariates that were associated with less driving mileage were polypharmacy (≥ 4 medications) and each year of additional age, yielding an average decrease of 8.3 (P = .01) and 0.4 miles per day (P = .02), respectively, over 2 years. CONCLUSION: In a cohort of older drivers, insomnia and the covariates of polypharmacy and advancing age were longitudinally associated with less daily driving mileage. Because reductions in driving mileage in older persons often occur in response to reductions in driving capacity, these results support a clinical approach that considers insomnia-based cognitive-behavioral therapy and reduced polypharmacy as strategies for improving driving capacity in older persons.

A pilot randomized controlled trial of a decision support tool to improve the quality of communication and decision-making in individuals with atrial fibrillation.

OBJECTIVES: To design a tool for nonvalvular atrial fibrillation (NVAF) to inform individuals of their individual stroke and bleeding risks, assist in clarifying priorities, and promote communication. DESIGN: Clustered randomized controlled trial. SETTING: Primary care clinics. PARTICIPANTS: Individuals with NVAF (N = 135). INTERVENTION: Completion of tool before regularly scheduled visit. MEASUREMENTS: Primary outcomes included the 100-point informed and values clarity subscales of the decisional conflict scale (lower scores indicate individual is more informed and has greater clarity). Secondary outcomes included knowledge, patient-clinician communication, and change in treatment. RESULTS: Sixty-nine individuals were enrolled in the intervention group and 66 in the control group. After their visit, intervention participants had lower scores on the informed (mean difference = -11.9, 95% confidence interval (CI) = -21.1 to -2.7) and values clarity subscales (mean difference = -14.6, 95% CI = -22.6 to -6.6). Greater proportions of intervention participants knew medications for reducing stroke risk (61% vs 31%, P < .001) and side effects (49% vs 37%, P = .07). Stroke (71% vs 12%) and bleeding risk (69% vs 20%) were discussed more frequently in the intervention than control group (P < .001). Five intervention participants expressed a preference for medication that was not concordant with their current treatment plan. There was no change in treatment plan in either group. CONCLUSION: The tool was effective in improving perceived and actual knowledge and values clarity and in increasing physician-patient communication but did not change treatment.

Promoting advance care planning as health behavior change: development of scales to assess Decisional Balance, Medical and Religious Beliefs, and Processes of Change.

OBJECTIVE: To develop measures representing key constructs of the Transtheoretical Model (TTM) of behavior change as applied to advance care planning (ACP) and to examine whether associations between these measures replicate the relationships posited by the TTM. METHODS: Sequential scale development techniques were used to develop measures for Decisional Balance (Pros and Cons of behavior change), ACP Values/Beliefs (religious beliefs and medical misconceptions serving as barriers to participation), Processes of Change (behavioral and cognitive processes used to foster participation) based on responses of 304 persons age≥65 years. RESULTS: Items for each scale/subscale demonstrated high factor loading (>.5) and good to excellent internal consistency (Cronbach α .76-.93). Results of MANOVA examining scores on the Pros, Cons, ACP Values/Beliefs, and POC subscales by stage of change for each of the six behaviors were significant, Wilks'λ=.555-.809, η(2)=.068-.178, p≤.001 for all models. CONCLUSION: Core constructs of the TTM as applied to ACP can be measured with high reliability and validity. PRACTICE IMPLICATIONS: Cross-sectional relationships between these constructs and stage of behavior change support the use of TTM-tailored interventions to change perceptions of the Pros and Cons of participation in ACP and promote the use of certain Processes of Change in order to promote older persons' engagement in ACP.

A cognitive-behavioral plus exercise intervention for older adults with chronic back pain: race/ethnicity effect?

This pilot study examined the feasibility and potential efficacy of a self-management program for seniors with chronic back pain and assessed for possible race/ethnicity differences in program impact. Sixty-nine seniors (24 African Americans, 25 Hispanics, and 20 non-Hispanic Whites) enrolled in the 8-wk community-based program. Efficacy outcomes included pain-related disability as measured by the Roland Morris Disability Questionnaire (RMDQ), pain intensity, pain self-efficacy, depressive symptoms, social activity, and functional status. Eighty percent of enrollees completed the program. Clinically important decreases in RMDQ scores were found for non-Hispanic White (adjusted change score = -3.53), African American (-3.89), and Hispanic (-8.45) participants. Improvements in all other outcomes were observed, but only for Hispanic participants. Results confirm that implementation of the protocol in urban senior centers is feasible, and the program shows potential efficacy. The race/ethnicity differences observed in the current study merit further investigation.
