Self-reported vision and hallucinations in older adults: results from two longitudinal US health surveys

BACKGROUND

Vision loss may be a risk factor for hallucinations, but this has not been studied at the population level.

METHODS

To determine the association between self-reported vision loss and hallucinations in a large community-based sample of older adults, we performed a cross-sectional and longitudinal analysis of two large, nationally representative US health surveys: the National Health and Aging Trends Study (NHATS) and the Health and Retirement Study (HRS). Visual impairment and hallucinations were self- or proxy-reported. Multivariate single and mixed effects logistic regression models were built to examine whether visual impairment and history of cataract surgery were associated with hallucinations.

RESULTS

In NHATS (n = 1520), hallucinations were more prevalent in those who reported difficulty reading newspaper print (OR 1.77, 95% confidence interval (CI): 1.32-2.39) or recognising someone across the street (OR 2.48, 95% CI: 1.86-3.31) after adjusting for confounders. In HRS (n = 3682), a similar association was observed for overall (OR 1.32, 95% CI: 1.08-1.60), distance (OR 1.61, 95% CI: 1.32-1.96) and near eyesight difficulties (OR 1.52, 95% CI: 1.25-1.85). In neither sample was there a significant association between cataract surgery and hallucinations after adjusting for covariates.

CONCLUSIONS

Visual dysfunction is associated with increased odds of hallucinations in the older US adult population. This suggests that the prevention and treatment of vision loss may potentially reduce the prevalence of hallucinations in older adults.

Quality and Value of Health Care in the Veterans Health Administration: A Qualitative Study

Background

The attitudes of Department of Veterans Affairs (VA) cardiovascular clinicians toward the VA's quality‐of‐care processes, clinical outcomes measures, and healthcare value are not well understood.

Methods and Results

Semistructured telephone interviews were conducted with cardiovascular healthcare providers (n=31) at VA hospitals that were previously identified as high or low performers in terms of healthcare value. The interviews focused on VA providers’ experiences with measures of processes, outcomes, and value (ie, costs relative to outcomes) of cardiovascular care. Most providers were aware of process‐of‐care measurements, received regular feedback generated from those data, and used that feedback to change their practices. Fewer respondents reported clinical outcomes measures influencing their practice, and virtually no participants used value data to inform their practice, although several described administrative barriers limiting high‐cost care. Providers also expressed general enthusiasm for the VA's quality measurement/improvement efforts, with relatively few criticisms about the workload or opportunity costs inherent in clinical performance data collection. There were no material differences in the responses of employees of low‐performing versus high‐performing VA medical centers.

Conclusions

Regardless of their medical center's healthcare value performance, most VA cardiovascular providers used feedback from process‐of‐care data to inform their practice. However, clinical outcomes data were used more rarely, and value‐of‐care data were almost never used. The limited use of outcomes data to inform healthcare practice raises concern that healthcare outcomes may have insufficient influence, whereas the lack of value data influencing cardiovascular care practices may perpetuate inefficiencies in resource use.

The Abdominal Hernia-Q: Development, Psychometric Evaluation, and Prospective Testing

OBJECTIVE

Our study completes the development and estimates the psychometric properties of a novel, ventral hernia-specific patient reported outcomes (PRO) tool-the Abdominal Hernia-Q (AHQ).

SUMMARY BACKGROUND DATA

A standardized method for measuring hernia-related PRO has not been identified. There remains a need for a broadly applicable, hernia-specific tool that incorporates patient viewpoints and offers pre- and postoperative forms.

METHODS

Concept elicitation interviews, focus groups, and cognitive debriefing interviews were completed to define content. The preoperative AHQ was administered to patients scheduled to have a ventral hernia repair (VHR). The postoperative AHQ was administered to patients within 24 months post-VHR. The SF-12 and HerQLes were concurrently administered. Psychometric evaluation was performed. Subsequently, the AHQ (pre: 8 items; post: 16 items) underwent prospective testing.

RESULTS

Cross-sectional evaluations of patient responses to the AHQ (pre n = 104; post n = 261) demonstrated high internal consistency (Cronbach α pre = 0.86; post = 0.90) and moderate disattenuated correlations with the HerQLes (pre r = -0.71 and post r = -0.70) and the SF-12 domains (pre and post r ≥ 0.5 for 7 of 8 domains). Principal components analyses produced 2 factors preoperatively and 3 factors postoperatively. In prospective testing (n = 67), the AHQ scores replicated the cross-sectional psychometric results and suggested sensitivity to clinical outcomes.

CONCLUSIONS

Through patient involvement and rigorous, iterative psychometric evaluation, we have produced substantial data to suggest the validity and reliability of AHQ scores in measuring hernia-specific PRO. The AHQ advances the clinical management and treatment of patients with abdominal hernias by providing a more complete understanding of patient-defined outcomes.

0196 Differences in Sleep Duration and Alertness Among Internal Medicine Interns Comparing Intensive Care Unit to General Medicine Rotations: A Secondary Analysis of the ICOMPARE Trial

Introduction

Little is known about the impact of specific rotations on medical residents’ sleep. The purpose of this analysis was to examine the difference in sleep duration and alertness among internal-medicine resident interns during intensive care unit (ICU) compared to general medicine (GM) rotations.

Methods

This is a secondary report of a randomized non-inferiority trial of 63 United States internal-medicine residency programs. Programs were assigned to either standard duty-hour (80h workweek/16h shifts) or flexible (80h workweek/no shift-length limit) policies. Interns were followed for 2 weeks during either a GM or ICU rotation. The primary outcome was sleep duration/24h (actigraphy). Secondary outcomes were sleepiness (Karolinska Sleepiness Scale [KSS]) and alertness (number of Brief Psychomotor Vigilance Test [PVT-B] lapses). Data were averaged across days (thirteen 24-hour periods). Linear mixed-effect models with random program intercept were used to determine the association between each outcome by rotation, controlling for age, sex, and policy followed.

Results

N=386 interns were included (mean age 27.9±2.1y, 194 (50.3%) males), with n=261 (67.6%) in GM, and n=125 (32.4%) in ICU. Average sleep duration was 7.00±0.08h and 6.84±0.10h for GM and ICU respectively (p=.09; 95%CI -0.02;0.33h). Percent of days with self-reports of excessive sleepiness were significantly more likely for ICU vs GM from 12am-6am (ICU: 20.2%; GM: 12.5%) and 6am-12pm (ICU: 20.5%; GM: 14.3%). GM had significantly more days with no excessive sleepiness (GM: 40.5%; ICU: 28.1%). Average KSS was 4.8±0.1 for both GM and ICU (p=.60; 95%CI -0.18;0.32). Average number of PVT-B lapses were 5.5±0.5 and 5.7±0.7 for GM and ICU respectively (p=.83; 95%CI -1.48;1.18 lapses). There were no significant differences in PVT-B response speed or false starts between rotations.

Conclusion

Interns in ICU may experience more excessive sleepiness compared to GM interns, especially in early morning hours. However, sleep duration and alertness were not significantly different between rotations.

0261 A Randomized Trial on The Effects of Standard and Flexible Duty-Hour Rules on Intern Sleep and Alertness

Introduction

Duty hour regulations affect resident sleep, education, and patient care in complex ways. We performed a national cluster-randomized trial (iCOMPARE) in 63 internal medicine residency programs comparing the effects of the 2011 duty-hour standards to a more flexible set of duty hour rules characterized by maintaining an 80-hour workweek but without limits on shift length or mandatory time off between shifts, relative to patient mortality, intern educational outcomes, and intern sleep and alertness.

Methods

In the sleep and alertness sub-study, sleep duration and morning sleepiness and alertness were assessed with actigraphy, the Karolinska Sleepiness Scale, and a 3-minute Psychomotor Vigilance Test (PVT-B) for 14 days in 193 interns from 6 standard programs and 205 interns from 6 flexible programs.

Results

During the 14-day study periods, interns in standard and flexible programs averaged 7.03h sleep/24h (95% confidence interval [CI] 6.78h, 7.27h) and 6.85h sleep/24h (95% CI 6.61h, 7.10h), respectively. Sleep duration (difference between arms of -0.17h/24h; 1-sided lower 95% confidence limit -0.45h; NIM -0.5h; P=0.02 for noninferiority) and KSS sleepiness (difference 0.12 points; 1-sided upper 95% confidence limit 0.31 points; NIM 1 point; P<0.001) were noninferior in flexible versus standard programs. We could not establish noninferiority for PVT-B alertness (difference -0.3 lapses; 1-sided upper 95% confidence limit 1.6 lapses; NIM 1 lapse; P=0.10). Based on analyses by shift type, sleep duration was 1.77h shorter on days when interns in flexible programs finished an overnight shift relative to a regular day shift (p<.001), with significant decreases in subjective and objective alertness, and frequent reports of excessive sleepiness, especially between 12am and 6am.

Conclusion

There were no signs of relevant chronic sleep loss across shifts in interns in flexible programs relative to their standard program counterparts. Interns were able to compensate for the sleep lost during extended overnight shifts by increasing sleep duration on nights prior to day shifts, night shifts, and days off. Increased sleepiness and reduced alertness of interns following extended overnight shifts need to be mitigated and suggest a role for fatigue-risk management programs.

A pragmatic randomized trial of cardiopulmonary resuscitation training for families of cardiac patients before hospital discharge using a mobile application

AIM OF THE STUDY

Since over 80% of sudden cardiac arrests occur in the home, cardiopulmonary resuscitation (CPR) training for family members of high-risk cardiac patients represents a promising intervention. The use of mobile application-based (mApp) CPR training may facilitate this approach, but evidence regarding its efficacy is lacking.

METHODS

We conducted a multicenter, pragmatic, cluster-randomized trial assessing CPR training for family members of cardiac patients. The interventions were mApp (video, no manikin) and VSI (video + manikin). CPR skills were evaluated 6-months post-training. We hypothesized that chest compression (CC) rate from training with an mApp would be no worse than 5 compressions per minute (CPM) lower compared to VSI.

RESULTS

From 01/2016 to 01/2018, we enrolled 1325 eligible participants (mean age 51.6 years, 68.2% female and 59.4% white). CPR skills were evaluated 6-months post-training in 541 participants (275 VSI, 266 mApp). Mean rate was 84.6 CPM (95% CI: 80.4, 88.6) in VSI, compared to 82.7 CPM (95% CI: 76.2, 89.1) in the mApp, and mean depth was 42.1 mm (95% CI: 40.3, 43.8) in VSI, compared to 38.9 mm (95% CI: 36.2, 41.6) in the mApp. After adjustment, the mean difference in CC rate was -2.3 CPM (95% CI -9.4, 4.8, p = 0.25, non-inferiority) and CC depth was -3.2 mm (95% CI -5.9, 0.1, p = 0.056).

CONCLUSION

In this large prospective trial of CPR skill retention for family members of cardiac patients, mApp training was associated with lower CC quality. Future work is required to understand additional approaches to improve CPR skill retention.

Perceived value drives use of routine asymptomatic surveillance PET/CT by physicians who treat head and neck cancer

BACKGROUND

Why physicians use surveillance imaging for asymptomatic cancer survivors despite recommendations against this is not known.

METHODS

Physicians surveilling head and neck cancer survivors were surveyed to determine relationships among attitudes, beliefs, guideline familiarity, and self-reported surveillance positron-emission-tomography/computed-tomography use.

RESULTS

Among 459 responses, 79% reported using PET/CT on some asymptomatic patients; 39% reported using PET/CT on more than half of patients. Among attitudes/beliefs, perceived value of surveillance imaging (O.R. 3.57, C.I. 2.42-5.27, P = <.0001) was the strongest predictor of high imaging, including beliefs about outcome (improved survival) and psychological benefits (reassurance, better communication). Twenty-four percent of physicians were unfamiliar with guideline recommendations against routine surveillance imaging. Among physicians with high perceived-value scores, those less familiar with guidelines imaged more (O.R. 3.55, C.I. 1.08-11.67, P = .037).

CONCLUSIONS

Interventions to decrease routine surveillance PET/CT use for asymptomatic patients must overcome physicians' misperceptions of its value. Education about guidelines may modify the effect of perceived value.

Assessing the relationship between housing and health among medically complex, chronically homeless individuals experiencing frequent hospital use in the United States

In the United States and abroad, health systems have begun to address housing insecurity through programs that adhere to the Housing First model. The model provides permanent supportive housing without disqualification due to current mental health problems or substance use, along with optional case management services. This study used qualitative methods to explore how housing stability affected chronic disease management and social and community relationships among individuals with complex health and social needs and patterns of high hospital utilisation who were housed as part of a scattered-site Housing First program in a mid-size city in the northeastern United States. 26 individual, semi-structured interviews were conducted with Housing First clients in their homes or day program sites between March and July 2017. Interviews were digitally recorded and transcripts were analysed using a qualitative descriptive methodology until thematic saturation was reached. Findings suggest that housing provided the physical location to manage the logistical aspects of care for these clients, and an environment where they were better able to focus on their health and wellness. Study participants reported less frequent use of emergency services and more regular interaction with primary care providers. Additionally, case managers' role in connecting clients to behavioural health services removed barriers to care that clients had previously faced. Housing also facilitated reconnection with family and friends whose relationships with participants had become strained or distant. Changes to physical and social communities sometimes resulted in experiences of stigmatisation and exclusion, especially for clients who moved to areas with less racial and socioeconomic diversity, but participation in the program promoted an increased sense of safety and security for many clients.

Insights Into Veterans' Perspectives on a Peer Support Program for Glycemic Management

PURPOSE

The purpose of this study was to explore the mentor-mentee relationship in veterans with type 2 diabetes and gain insight into successful pairings.

METHODS

Qualitative semistructured interviews were conducted as part of a peer mentoring randomized controlled trial to understand participants' experiences, their relationship with their partner, and how the intervention affected self-care behaviors. Purposive sampling was done to ensure adequate representation of mentees who made large strides in reaching their glycemic targets, those who made marginal improvements toward their glycemic goals, and those who got worse. All interviews were audio-recorded, transcribed, and analyzed for salient themes.

RESULTS

The intervention was well received, with most participants describing it as valuable. Participants perceived the intervention to have a number of benefits, including accessible support, enhanced self-confidence, increased accountability, better self-efficacy, improved glycemic management, and a fulfilled sense of altruism. Participants did encounter barriers, including logistical, interpersonal, and individual obstacles. The more successful mentees tended to be more effusive in their description of their mentors, endorsed a stronger sense of connection to their mentor, described a more structured interaction with their mentor, and tended to be more complimentary of the intervention.

CONCLUSIONS

Large peer support programs are appealing and well received. These programs can be optimized by selecting naturally inclined mentors, providing additional training to introduce more structure into mentorship interactions, and targeting mentees who are not struggling with overwhelming comorbidities.

Physician Perspectives In Year 1 Of MACRA And Its Merit-Based Payment System: A National Survey

We surveyed a national sample of internal medicine physicians in March-May 2017 to explore their beliefs about the newly implemented Merit-based Incentive Payment System (MIPS). Respondents believed that their efforts in the four focus areas identified in the survey would ultimately improve the value of care. When informed that those areas represented the four MIPS domains, the majority remained positive about the likely impact on value. However, expectations varied by physicians' characteristics and sense of control over the desired outcomes, and many respondents believed that unintended consequences could occur. Moreover, respondents generally reported low familiarity with the policy and disagreed with program guidelines for weighting domains in the composite score. These findings indicate the need to educate physicians about MIPS and suggest potentially fruitful approaches. Moving forward, policy makers should monitor for unintended consequences and explore ways to better align program guidelines with physicians' perspectives.

Assessment of Inpatient Time Allocation Among First-Year Internal Medicine Residents Using Time-Motion Observations

IMPORTANCE

The United States spends more than $12 billion annually on graduate medical education. Understanding how residents balance patient care and educational activities may provide insights into how the modern physician workforce is being trained.

OBJECTIVE

To describe how first-year internal medicine residents (interns) allocate time while working on general medicine inpatient services.

DESIGN, SETTING, AND PARTICIPANTS

Direct observational secondary analysis, including 6 US university-affiliated and community-based internal medicine programs in the mid-Atlantic region, of the Comparative Effectiveness of Models Optimizing Patient Safety and Resident Education (iCOMPARE) trial, a cluster-randomized trial comparing different duty-hour policies. A total of 194 weekday shifts were observed and time motion data were collected, sampled by daytime, nighttime, and call shifts in proportion to the distribution of shifts within each program from March 10 through May 31, 2016. Data were analyzed from June 1, 2016, through January 5, 2019.

MAIN OUTCOMES AND MEASURES

Mean time spent in direct and indirect patient care, education, rounds, handoffs, and miscellaneous activities within a 24-hour period and in each of four 6-hour periods (morning, afternoon, evening, and night). Time spent multitasking, simultaneously engaged in combinations of direct patient care, indirect patient care, or education, and in subcategories of indirect patient care were tracked.

RESULTS

A total of 80 interns (55% men; mean [SD] age, 28.7 [2.3] years) were observed across 194 shifts, totaling 2173 hours. A mean (SD) of 15.9 (0.7) hours of a 24-hour period (66%) was spent in indirect patient care, mostly interactions with the patient's medical record or documentation (mean [SD], 10.3 [0.7] hours; 43%). A mean (SD) of 3.0 (0.1) hours was spent in direct patient care (13%) and 1.8 (0.3) hours in education (7%). This pattern was consistent across the 4 periods of the day. Direct patient care and education frequently occurred when interns were performing indirect patient care. Multitasking with 2 or more indirect patient care activities occurred for a mean (SD) of 3.8 (0.4) hours (16%) of the day.

CONCLUSIONS AND RELEVANCE

This study's findings suggest that within these US teaching programs, interns spend more time participating in indirect patient care than interacting with patients or in dedicated educational activities. These findings provide an essential baseline measure for future efforts designed to improve the workday structure and experience of internal medicine trainees, without making a judgment on the current allocation of time.

Hospitals Using Bundled Payment Report Reducing Skilled Nursing Facility Use And Improving Care Integration

A goal of Medicare's bundled payment models is to improve quality and control costs after hospital discharge. Little is known about how participating hospitals are focusing their efforts to achieve these objectives, particularly around the use of skilled nursing facilities (SNFs). To understand hospitals' approaches, we conducted semistructured interviews with an executive or administrator in each of twenty-two hospitals and health systems participating in Medicare's Comprehensive Care for Joint Replacement model or its Bundled Payments for Care Improvement initiative for lower extremity joint replacement episodes. We identified two major organizational responses. One principal strategy was to reduce SNF referrals, using risk-stratification tools, patient education, home care supports, and linkages with home health agencies to facilitate discharges to home. Another was to enhance integration with SNFs: fifteen hospitals or health systems in our sample had formed networks of preferred SNFs to exert influence over SNF quality and costs. Common coordination strategies included sharing access to electronic medical records, embedding providers across facilities, hiring dedicated care coordination staff, and creating platforms for data sharing. As hospitals presumably move toward home-based care and more selective SNF referrals, more evidence is needed to understand how these discharge practices affect the quality of care and patient outcomes.

The association of financial incentives for low density lipoprotein cholesterol reduction with patient activation and motivation

There is growing interest in using financial incentives for patients to improve medication adherence, but few studies have evaluated whether financial incentives are associated with patients' activation and motivation. We analyzed survey data collected as part of a randomized clinical trial conducted from 2011 to 2014 of four financial incentive interventions to reduce low density lipoprotein cholesterol (LDL-C) among patients at risk for atherosclerotic cardiovascular disease. The main trial included 1503 patients aged 18–80 and recruited from primary care practices affiliated with three health systems. Participants were randomized into four groups: patient financial incentives, primary care physicians (PCPs) incentives, patients and PCPs shared incentives, or no incentives for LDL-C control. Patient Activation Measure (PAM) and Treatment Self Regulation Questionnaire (TSRQ) surveys were administered at baseline and 12 months. Clinical outcomes were change in LDL-C at 12 and 15 months and average medication adherence as measured by electronic pill bottle opening. Mean changes in PAM and TSRQ scores were compared between patients eligible and not eligible for incentives. Clinical outcomes were tested against baseline and change in psychosocial measures using bivariate and multivariate regression. Change in PAM score and TSRQ autonomous subscore did not differ significantly between patients eligible and not eligible for incentives. Lower baseline and greater increase in TSRQ autonomous subscore were predictive of greater 15-month decrease in LDL-C. A financial incentive intervention to improve LDL-C control was not associated with changes in patients' activation or autonomous motivation. Increases in patient autonomous motivation are predictive of long-term LDL-C control.

•

Financial incentives for lipid control were not associated with changes in activation or motivation.

•

Participants had high activation and motivation levels at baseline.

•

Increases in autonomous motivation were associated with better lipid control at 15 months.

Sleep and Alertness in a Duty-Hour Flexibility Trial in Internal Medicine

BACKGROUND

A purpose of duty-hour regulations is to reduce sleep deprivation in medical trainees, but their effects on sleep, sleepiness, and alertness are largely unknown.

METHODS

We randomly assigned 63 internal-medicine residency programs in the United States to follow either standard 2011 duty-hour policies or flexible policies that maintained an 80-hour workweek without limits on shift length or mandatory time off between shifts. Sleep duration and morning sleepiness and alertness were compared between the two groups by means of a noninferiority design, with outcome measures including sleep duration measured with actigraphy, the Karolinska Sleepiness Scale (with scores ranging from 1 [extremely alert] to 9 [extremely sleepy, fighting sleep]), and a brief computerized Psychomotor Vigilance Test (PVT-B), with long response times (lapses) indicating reduced alertness.

RESULTS

Data were obtained over a period of 14 days for 205 interns at six flexible programs and 193 interns at six standard programs. The average sleep time per 24 hours was 6.85 hours (95% confidence interval [CI], 6.61 to 7.10) among those in flexible programs and 7.03 hours (95% CI, 6.78 to 7.27) among those in standard programs. Sleep duration in flexible programs was noninferior to that in standard programs (between-group difference, -0.17 hours per 24 hours; one-sided lower limit of the 95% confidence interval, -0.45 hours; noninferiority margin, -0.5 hours; P = 0.02 for noninferiority), as was the score on the Karolinska Sleepiness Scale (between-group difference, 0.12 points; one-sided upper limit of the 95% confidence interval, 0.31 points; noninferiority margin, 1 point; P<0.001). Noninferiority was not established for alertness according to the PVT-B (between-group difference, -0.3 lapses; one-sided upper limit of the 95% confidence interval, 1.6 lapses; noninferiority margin, 1 lapse; P = 0.10).

CONCLUSIONS

This noninferiority trial showed no more chronic sleep loss or sleepiness across trial days among interns in flexible programs than among those in standard programs. Noninferiority of the flexible group for alertness was not established.

Patient Safety Outcomes under Flexible and Standard Resident Duty-Hour Rules

BACKGROUND

Concern persists that extended shifts in medical residency programs may adversely affect patient safety.

METHODS

We conducted a cluster-randomized noninferiority trial in 63 internal-medicine residency programs during the 2015-2016 academic year. Programs underwent randomization to a group with standard duty hours, as adopted by the Accreditation Council for Graduate Medical Education (ACGME) in July 2011, or to a group with more flexible duty-hour rules that did not specify limits on shift length or mandatory time off between shifts. The primary outcome for each program was the change in unadjusted 30-day mortality from the pretrial year to the trial year, as ascertained from Medicare claims. We hypothesized that the change in 30-day mortality in the flexible programs would not be worse than the change in the standard programs (difference-in-difference analysis) by more than 1 percentage point (noninferiority margin). Secondary outcomes were changes in five other patient safety measures and risk-adjusted outcomes for all measures.

RESULTS

The change in 30-day mortality (primary outcome) among the patients in the flexible programs (12.5% in the trial year vs. 12.6% in the pretrial year) was noninferior to that in the standard programs (12.2% in the trial year vs. 12.7% in the pretrial year). The test for noninferiority was significant (P = 0.03), with an estimate of the upper limit of the one-sided 95% confidence interval (0.93%) for a between-group difference in the change in mortality that was less than the prespecified noninferiority margin of 1 percentage point. Differences in changes between the flexible programs and the standard programs in the unadjusted rate of readmission at 7 days, patient safety indicators, and Medicare payments were also below 1 percentage point; the noninferiority criterion was not met for 30-day readmissions or prolonged length of hospital stay. Risk-adjusted measures generally showed similar findings.

CONCLUSIONS

Allowing program directors flexibility in adjusting duty-hour schedules for trainees did not adversely affect 30-day mortality or several other measured outcomes of patient safety.

Feasibility and Construct Validation of the Patient Reported Outcomes Measurement Information System in Systemic Vasculitis

OBJECTIVE

The Patient Reported Outcome Measurement Information System (PROMIS) is a collection of item banks of self-reported health. This study assessed the feasibility and construct validity of using PROMIS instruments in vasculitis.

METHODS

Data from a multicenter longitudinal cohort of subjects with systemic vasculitis were used. Instruments from 10 PROMIS item banks were selected with direct involvement of patients. Subjects completed PROMIS instruments using computer adaptive testing (CAT). The Medical Outcomes Study Short Form-36 (SF-36) was also administered. Cross-sectional construct validity was assessed by calculating correlations of PROMIS scores with SF-36 measures and physician and patient global scores for disease activity. Longitudinal construct validity was assessed by correlations of between-visit differences in PROMIS scores with differences in other measures.

RESULTS

During the study period, 973 subjects came for 2306 study visits and the PROMIS collection was completed at 2276 (99%) of visits. The median time needed to complete each PROMIS instrument ranged from 40 to 55 s. PROMIS instruments correlated cross-sectionally with individual scales of the SF-36, most strongly with subscales of the SF-36 addressing the same domain as the PROMIS instrument. For example, PROMIS fatigue correlated with both the physical component score (PCS; r = -0.65) and with the mental component score (MCS; r = -0.54). PROMIS physical function correlated strongly with PCS (r = 0.81) but weakly with MCS (r = 0.29). Weaker correlations were observed longitudinally between change in PROMIS scores with change in PCS and MCS.

CONCLUSION

Collection of data using CAT PROMIS instruments is feasible among patients with vasculitis and has some cross-sectional and longitudinal construct validity.

Patients' Perspectives on Approaches to Facilitate Completion of Advance Directives

BACKGROUND

Little is understood about the different ways patients complete advance directives (ADs), which is most commonly through lawyers and increasingly using websites.

OBJECTIVE

To understand patients' perspectives on different approaches to facilitating AD completion, the value of legal regulation of ADs, and the use of a web-based platform to create an AD.

DESIGN

Semi-structured interviews with patients.

SETTING/PARTICIPANTS

We purposively sampled 25 patients at least 70 years of age or with a chronic disease from 2 internal medicine clinics.

MEASUREMENTS

Interviews focused on experiences and perspectives creating ADs, including facilitation by lawyers, health-care professionals, and websites. Feedback on a website prototype was also obtained. Responses were analyzed with modified grounded theory until thematic saturation was achieved.

RESULTS

Although a majority of participants with ADs had used lawyers, participants were ambivalent about the benefits of lawyer facilitation. Most valued both the medical perspective of a health-care professional and a lawyer's attention to legal requirements for AD validity. Participants had positive impressions of the web platform, but some were concerned about privacy with online storage. Trust emerged as an overarching theme, and participants valued legal regulation of ADs to ensure document authenticity and delivery of preference-concordant care.

CONCLUSION

Efforts to improve documentation of care planning need to address the disparate methods by which participants complete ADs. Creating options that combine the perceived benefits of a legal approach with greater health professional involvement could appeal to participants. Privacy concerns may limit web use by some patients.
