Challenges in Deprescribing among Older Adults in Post-Acute Care Transitions to Home.

OBJECTIVES: Medications with a higher risk of harm or that are unlikely to be beneficial are used by nearly all older patients in home health care (HHC). The objective of this study was to understand stakeholders' perspectives on challenges in deprescribing these medications for post-acute HHC patients. DESIGN: Qualitative individual interviews were conducted with stakeholders involved with post-acute deprescribing. SETTING AND PARTICIPANT: Older HHC patients, HHC nurses, pharmacists, and primary/acute care/post-acute prescribers from 9 US states participated in individual qualitative interviews. MEASURES: Interview questions were focused on the experience, processes, roles, training, workflow, and challenges of deprescribing in hospital-to-home transitions. We used the constant comparison approach to identify and compare findings among patient, prescriber, and pharmacist and HHC nurse stakeholders. RESULTS: We interviewed 9 older patients, 11 HHC nurses, 5 primary care physicians (PCP), 3 pharmacists, 1 hospitalist, and 1 post-acute nurse practitioner. Four challenges were described in post-acute deprescribing for HHC patients. First, PCPs' time constraints, the timing of patient encounters after hospital discharge, and the lack of prioritization of deprescribing make it difficult for PCPs to initiate post-acute deprescribing. Second, patients are often confused about their medications, despite the care team's efforts in educating the patients. Third, communication is challenging between HHC nurses, PCPs, specialists, and hospitalists. Fourth, the roles of HHC nurses and pharmacists are limited in care team collaboration and discussion about post-acute deprescribing. CONCLUSIONS AND IMPLICATIONS: Post-acute deprescribing relies on multiple parties in the care team yet it has challenges. Interventions to align the timing of deprescribing and that of post-acute care visits, prioritize deprescribing and allow clinicians more time to complete related tasks, improve medication education for patients, and ensure effective communication in the care team with synchronized electronic health record systems are needed to advance deprescribing during the transition from hospital to home.

How to Deprescribe Potentially Inappropriate Medications During the Hospital-to-Home Transition: Stakeholder Perspectives on Essential Tasks.

PURPOSE: Nearly all older patients receiving postacute home health care (HHC) use potentially inappropriate medications (PIMs) that carry a risk of harm. Deprescribing can reduce and optimize the use of PIMs, yet it is often not conducted among HHC patients. The objective of this study was to gather perspectives from patient, practitioner, and HHC clinician stakeholders on tasks that are essential to postacute deprescribing in HHC. METHODS: A total of 44 stakeholders, including 14 HHC patients, 15 practitioners (including 9 primary care physicians, 4 pharmacists, 1 hospitalist, and 1 nurse practitioner), and 15 HHC nurses, participated. The stakeholders were from 12 US states, including New York (n = 29), Colorado (n = 2), Connecticut (n = 1), Illinois (n = 2), Kansas (n = 2), Massachusetts (n = 1), Minnesota (n = 1), Mississippi (n = 1), Nebraska (n = 1), Ohio (n = 1), Tennessee (n = 1), and Texas (n = 2). First, individual interviews were conducted by experienced research staff via video conference or telephone. Second, the study team reviewed all interview transcripts and selected interview statements regarding stakeholders' suggestions for important tasks needed for postacute deprescribing in HHC. Third, concept mapping was conducted in which stakeholders sorted and rated selected interview statements regarding importance and feasibility. A content analysis was conducted of data collected in the individual interviews, and a mixed-method analysis was conducted of data collected in the concept mapping. FINDINGS: Four essential tasks were identified for postacute deprescribing in HHC: (1) ongoing review and assessment of medication use, (2) patent-centered and individualized plan of deprescribing, (3) timely and efficient communication among members of the care team, and (4) continuous and tailored medication education to meet patient needs. Among these tasks, developing patient-centered deprescribing considerations was considered the most important and feasible, followed by medication education, review and assessment of medication use, and communication. IMPLICATIONS: Deprescribing during the transition of care from hospital to home requires the following: continuous medication education for patients, families, and caregivers; ongoing review and assessment of medication use; patient-centered deprescribing considerations; and effective communication and collaboration among the primary care physician, HHC nurse, and pharmacist.

Procurement of patient medical records from multiple health care facilities for public health research: feasibility, challenges, and lessons learned.

Objectives: Studies that combine medical record and primary data are typically conducted in a small number of health care facilities (HCFs) covering a limited catchment area; however, depending on the study objectives, validity may be improved by recruiting a more expansive sample of patients receiving care across multiple HCFs. We evaluate the feasibility of a novel protocol to obtain patient medical records from multiple HCFs using a broad representative sampling frame. Materials and Methods: In a prospective cohort study on HIV pre-exposure prophylaxis utilization, primary data were collected from a representative sample of community-dwelling participants; voluntary authorization was obtained to access participants' medical records from the HCF at which they were receiving care. Medical record procurement procedures were documented for later analysis. Results: The cohort consisted of 460 participants receiving care from 122 HCFs; 81 participants were lost to follow-up resulting in 379 requests for medical records submitted to HCFs, and a total of 343 medical records were obtained (91% response rate). Less than 20% of the medical records received were in electronic form. On average, the cost of medical record acquisition was $120 USD per medical record. Conclusions: Obtaining medical record data on research participants receiving care across multiple HCFs was feasible, but time-consuming and resulted in appreciable missing data. Researchers combining primary data with medical record data should select a sampling and data collection approach that optimizes study validity while weighing the potential benefits (more representative sample; inclusion of HCF-level predictors) and drawbacks (cost, missing data) of obtaining medical records from multiple HCFs.

The Magnetic Couples Study: protocol for a mixed methods prospective cohort study of HIV-serodifferent heterosexual couples' perspectives and use of pre-exposure prophylaxis (PrEP).

INTRODUCTION: HIV transmission within serodifferent heterosexual couples plays a key role in sustaining the global HIV pandemic. In the USA, transmission within established mixed-status couples accounts for up to half of all new HIV infections among heterosexuals. Oral HIV pre-exposure prophylaxis (PrEP) is a highly effective prevention method, although underutilised among serodifferent couples. Moreover, there is a dearth of research on US HIV-serodifferent couples' perspectives and use of PrEP, alone or in combination with other prevention methods. In this paper, we describe the study protocol for the Magnetic Couples Study, designed to fill critical knowledge gaps regarding HIV-serodifferent heterosexual couples' perspectives, experiences and utilisation of PrEP. METHODS AND ANALYSIS: The Magnetic Couples Study is a mixed methods prospective cohort study designed to describe temporal patterns and identify determinants at multiple levels (individual, couple, HCF) of PrEP outcomes along the care continuum (PrEP awareness, linkage, uptake, retention and medication adherence) among HIV-serodifferent heterosexual couples residing in New York City. The study will also examine clinical management of PrEP, side effects and changes in sexual-related and substance use-related behaviour. A prospective cohort of 230 mixed-status couples already on oral PrEP was recruited, with quarterly assessments over 18 months; in addition, a cross-sectional sample of 150 mixed-status couples not currently on PrEP was recruited. In-depth semistructured qualitative interviews were conducted with a subsample of 25 couples. Actor-partner interdependence modelling using multilevel analysis will be employed for the analysis of longitudinal dyadic data. Framework analysis will be used to analyse qualitative data. A parallel convergent design will be used for mixed methods integration. ETHICS AND DISSEMINATION: The study was approved by the University of Rochester Institutional Review Board (RSRB00052766). Study findings will be disseminated to community members and providers and to researchers and policy makers.

Autonomy-Supportive Healthcare Climate and HIV-Related Stigma Predict Linkage to HIV Care in Men Who Have Sex With Men in Ghana, West Africa.

In Ghana, the HIV prevalence among MSM is more than 10 times greater than the general population of adults, and rates of engagement in HIV medical care are low among MSM diagnosed with HIV. Using structured surveys, we investigated the impact of HIV-related stigma, same-sex behavior stigma, and gender nonconformity stigma on linkage to HIV care (LTC) in MSM (N = 225) living with HIV in Ghana. Autonomy-supportive healthcare climate (OR = 1.63, p < .01), vicarious HIV stigma (OR = 2.73, p < .01), and age (OR = 1.06, p < .004) predicted LTC. Conversely, felt normative HIV stigma negatively predicted LTC (OR = 0.65, p < .05). Finally, we identified regional disparities, with MSM from Takoradi being 4 times and 5 times more likely to be LTC compared to Kumasi and Accra, respectively. Our findings highlight the nuanced roles of stigmas in shaping the HIV care continuum among MSM living with HIV, while revealing potential gaps in current measures of HIV-related stigma.

A pilot study of multifamily therapy group for young adults with anorexia nervosa: Reconnecting for recovery.

OBJECTIVE: We tested the feasibility, acceptability, and preliminary effect sizes on outcome measures of Reconnecting for Recovery (R4R) Multifamily Therapy Group for young adults with anorexia nervosa (AN). METHOD: Ten participants (mean age = 23 years, SD = 3.6) meeting Diagnostic and Statistical Manual of Mental Disorders 5th Edition criteria for a restrictive eating disorder (AN or other specified feeding and eating disorder) and 14 family members received 16 R4R outpatient sessions over 26 weeks. Feasibility and acceptability were evaluated by recruitment and retention rates and patient/family member suitability scores. Outcomes were determined utilizing the Eating Disorder Examination (EDE), weight (body mass index), and Difficulties in Emotion Regulation Scale. RESULTS: All participants and 12 family members were retained, and the majority found R4R acceptable. EDE global score and lack of emotional awareness improved significantly from baseline (BL) to end-of-treatment (EOT) and BL to 6-month follow-up (6MFU) with moderate to large effect sizes (0.47-1.41). Limited access to emotion regulation strategies (LAERS) improved significantly from BL to 6MFU (moderate effect size; 0.57). Improvements in LAERS from BL to EOT (0.32) and weight from BL to EOT and BL to 6MFU were not significant (effect sizes 0.16-0.22). DISCUSSION: Findings provide preliminary evidence that R4R is feasible, acceptable, and produces clinically significant changes in targeted outcomes.

Exploring relationships of catheter-associated urinary tract infection and blockage in people with long-term indwelling urinary catheters.

AIMS AND OBJECTIVES: To describe and explore relationships among catheter problems in long-term indwelling urinary catheter users, including excess healthcare use for treating catheter problems. BACKGROUND: Long-term urinary catheter users experience repeated problems with catheter-related urinary tract infection and blockage of the device, yet little has been reported of the patterns and relationships among relevant catheter variables. DESIGN: Secondary data analysis was conducted from a sample in a randomised clinical trial, using data from the entire sample of 202 persons over 12 months' participation. METHODS: Descriptive statistics were used to characterise the sample over time. Zero-inflated negative binomial models were employed for logistic regressions to evaluate predictor variables of the presence/absence and frequencies of catheter-related urinary tract infection and blockage. RESULTS: Catheter-related urinary tract infection was marginally associated with catheter blockage. Problems reported at least once per person in the 12 months were as follows: catheter-related urinary tract infection 57%, blockage 34%, accidental dislodgment 28%, sediment 87%, leakage (bypassing) 67%, bladder spasms 59%, kinks/twists 42% and catheter pain 49%. Regression analysis demonstrated that bladder spasms were significantly related to catheter-related urinary tract infection and sediment amount, and catheter leakages were marginally significantly and positively related to catheter-related urinary tract infection. Frequencies of higher levels of sediment and catheter leakage were significantly associated with higher levels of blockage, and being female was associated with fewer blockages. Persons who need help with eating (more disabled) were also more likely to have blockages. CONCLUSIONS: Catheter-related urinary tract infection and blockage appear to be related and both are associated with additional healthcare expenditures. More research is needed to better understand how to prevent adverse catheter outcomes and patterns of problems in subgroups. RELEVANCE TO CLINICAL PRACTICE: Nurses can develop care management strategies to identify catheter blockage prior to its occurrence by tracking the amount of sediment and frequency of leakage. Bladder spasms could be an early warning of catheter-related urinary tract infection.

Feasibility of a Web-Based Self-management Intervention for Intermittent Urinary Catheter Users With Spinal Cord Injury.

PURPOSE: The purpose of this study was to evaluate the feasibility of a new Web-based intermittent catheter self-management intervention. DESIGN: We tested the acceptability and usability of intervention components, which included multiple Web-based materials (an online urinary diary adapted for mobile phone use and an educational booklet), 3 phone calls with a nurse, and a peer-led discussion forum. SUBJECTS AND SETTING: Thirty adults with spinal cord injury using intermittent catheterization for bladder drainage were enrolled; 26 participants received the nurses' phone-based consultations. METHODS: Preliminary effectiveness of new self-efficacy and self-management scales were evaluated using baseline and 3-month online surveys. Participants' perceived value of the intervention components, self-management changes, and suggestions were assessed with data from the 3-month surveys, followed by brief tape-recorded interviews. RESULTS: Several catheter practices improved somewhat over 3 months. The frequency of catheterizations every 4 to 6 hours increased from 71% to 77%. Self-management of neurogenic bladder dysfunction increased significantly (P = .032); participant comments indicated that fluid intake was the biggest change. Catheter-related self-efficacy and quality-of-life scores increased but not significantly. The frequency of urinary tract infection and pain did not change significantly. For feasibility, intervention components, with the exception of the forum, were rated highly by the majority of participants for usefulness, satisfaction (desired information), and Web-based usability. CONCLUSION: Further testing of this intervention is recommended in a multisite randomized clinical trial.

Cognitive and Neural Effects of Vision-Based Speed-of-Processing Training in Older Adults with Amnestic Mild Cognitive Impairment: A Pilot Study.

OBJECTIVES: To examine the cognitive and neural effects of vision-based speed-of-processing (VSOP) training in older adults with amnestic mild cognitive impairment (aMCI) and contrast those effects with an active control (mental leisure activities (MLA)). DESIGN: Randomized single-blind controlled pilot trial. SETTING: Academic medical center. PARTICIPANTS: Individuals with aMCI (N = 21). INTERVENTION: Six-week computerized VSOP training. MEASUREMENTS: Multiple cognitive processing measures, instrumental activities of daily living (IADLs), and two resting state neural networks regulating cognitive processing: central executive network (CEN) and default mode network (DMN). RESULTS: VSOP training led to significantly greater improvements in trained (processing speed and attention: F1,19  = 6.61, partial η(2)  = 0.26, P = .02) and untrained (working memory: F1,19  = 7.33, partial η(2)  = 0.28, P = .01; IADLs: F1,19  = 5.16, partial η(2)  = 0.21, P = .03) cognitive domains than MLA and protective maintenance in DMN (F1, 9  = 14.63, partial η(2)  = 0.62, P = .004). VSOP training, but not MLA, resulted in a significant improvement in CEN connectivity (Z = -2.37, P = .02). CONCLUSION: Target and transfer effects of VSOP training were identified, and links between VSOP training and two neural networks associated with aMCI were found. These findings highlight the potential of VSOP training to slow cognitive decline in individuals with aMCI. Further delineation of mechanisms underlying VSOP-induced plasticity is necessary to understand in which populations and under what conditions such training may be most effective.

Testing a Model of Self-Management of Fluid Intake in Community-Residing Long-term Indwelling Urinary Catheter Users.

BACKGROUND: Urinary tract infection and blockage are serious and recurrent challenges for people with long-term indwelling catheters, and these catheter problems cause worry and anxiety when they disrupt normal daily activities. OBJECTIVE: The goal was to determine whether urinary catheter-related self-management behaviors focusing on fluid intake would mediate fluid intake-related self-efficacy toward decreasing catheter-associated urinary tract infection (CAUTI) and/or catheter blockage. METHODS: The sample involved data collected from 180 adult community-living, long-term indwelling urinary catheter users. The authors tested a model of fluid intake self-management related to fluid intake self-efficacy for key outcomes of CAUTI and blockage. To account for the large number of zeros in both outcomes, a zero-inflated negative binomial (ZINB) structural equation model was tested. RESULTS: Structurally, fluid intake self-efficacy was positively associated with fluid intake self-management, suggesting that higher fluid intake self-efficacy predicts more (higher) fluid intake self-management; however, fluid intake self-management was not associated with either the frequency of CAUTIs or the presence or absence of CAUTI. Fluid intake self-efficacy was positively related to fluid intake self-management, and fluid intake self-management predicted less frequency of catheter blockage, but neither fluid intake self-efficacy nor fluid intake self-management predicted the presence or absence of blockage. DISCUSSION: Further research is needed to better understand determinants of CAUTI in long-term catheter users and factors which might influence or prevent its occurrence. Increased confidence (self-efficacy) and self-management behaviors to promote fluid intake could be of value to long-term urinary catheter users to decrease catheter blockage.

Self-care management questionnaire for long-term indwelling urinary catheter users.

AIMS: Self-management is believed to be an important behavioral capacity in people with chronic illness, and self-efficacy is an important component contributing to self-management. Two new and related measures for urinary catheter self-efficacy (C-SE) and self-management (C-SMG) were developed based on existing tools and tested for psychometrics for use in a randomized clinical trial (RCT) teaching urinary catheter self-management. METHODS: The instruments were evaluated at baseline (intake face to face interview) with 202 persons and with 158 of the same individuals 6 months later by telephone interviews. Exploratory factor analysis was conducted in an iterative process related to items' theoretical and statistical appropriateness. To assess construct validity and goodness of fit for model testing, confirmatory factor analysis was conducted with the samples at intake and 6 months. Also, bivariate analyses were conducted of the measures in relation to each other. RESULTS: Both scales were modified reducing the items to 13 in each, with four factors in C-SE and three factors in C-SMG. Reliability testing (Cronbach's alpha) was viewed as satisfactory for both scales, though some of the subscale (factors) reliabilities were lower in the self-management measure. Confirmatory factor analysis was adequate. Correlation of the two instruments (r = 0.25, P < 001) suggests that they are related scales. CONCLUSION: With a change in the C-SMG scale from 3- to 5-level responses and subsequent testing, both new scales are appropriate for use separately or together as a questionnaire related to catheter self-care management in intervention research with long-term indwelling urinary catheter users.

Development of a Web-Based Self-management Intervention for Intermittent Urinary Catheter Users With Spinal Cord Injury.

While Web-based interventions have proliferated recently, information in the literature is often lacking about how the intervention was developed. In response to that gap, this is a report of the development of a Web-based self-management intervention for intermittent urinary catheter users and pretesting with four adults with spinal cord injury living in the community. Two Web sites were created, one for recruitment and the other for the intervention itself. The intervention involved developing new Web-based technology, including an interactive urinary diary (with fluid intake/urine output and a journal), extensive catheter products information, three intervention nurse phone call consultations, and user-community discussion forums. Study participants completed an online survey and were interviewed twice about the enrollment process and their perceptions of their involvement in the intervention. Suggestions from the pretesting participants were used to revise the Web site applications prior to the next stage of research (a feasibility study). Numerous recommendations and comments were received related to content, interactivity of components, and usability. This article provides a description of how the Web sites were developed (including the technology and software programs used), issues encountered and what was done to address them, and how the Web-based intervention was modified for improvements.

A Web-Based Self-Management Intervention for Intermittent Catheter Users.

A new Web-based self-management intervention was developed for persons with spinal cord injury who use intermittent urinary catheters. Included are a description of the components, examples from the educational book, and multiple screen shots of the online urinary diary.

A hybrid process fidelity assessment in a home-based randomized clinical trial.

A process fidelity assessment was conducted as a nested study within a home-based randomized clinical trial teaching self-management to 101 long-term indwelling urinary catheter users in the treatment group. Our hybrid model combined external assessments (outside observations and tape recordings) with internal evaluation methods (through study nurse forms and notes) for a comprehensive process fidelity assessment. Barriers, patient-related issues, and nurse perspectives were identified demonstrating the complexity in home care intervention research. The complementary and synergistic approaches provided in-depth information about the context of the delivery and the impact of the intervention on study outcomes.

Self-management intervention for long-term indwelling urinary catheter users: randomized clinical trial.

BACKGROUND: People using long-term indwelling urinary catheters experience multiple recurrent catheter problems. Self-management approaches are needed to avoid catheter-related problems. OBJECTIVES: The aim was to determine effectiveness of a self-management intervention in prevention of adverse outcomes (catheter-related urinary tract infection, blockage, and accidental dislodgement). Healthcare treatment associated with the adverse outcomes and catheter-related quality of life was also studied. METHODS: A randomized clinical trial was conducted. The intervention involved learning catheter-related self-monitoring and self-management skills during home visits by a study nurse (twice during the first month and at 4 months-with a phone call at 2 months). The control group received usual care. Data were collected during an initial face-to-face home interview followed by bimonthly phone interviews. A total of 202 adult long-term urinary catheter users participated. Participants were randomized to treatment or control groups following collection of baseline data. Generalized estimating equations were used for the analysis of treatment effect. RESULTS: In the intervention group, there was a significant decrease in reported blockage in the first 6 months (p = .02), but the effect did not persist. There were no significant effects for catheter-related urinary tract infection or dislodgment. Comparison of baseline rates of adverse outcomes with subsequent periods suggested that both groups improved over 12 months. DISCUSSION: A simple-to-use catheter problems calendar and the bimonthly interviews might have functioned as a modest self-monitoring intervention for persons in both groups. A simplified intervention using a self-monitoring calendar is suggested-with optimal and consistent fluid intake likely to add value.

Successful recruitment methods in the community for a two-site clinical trial.

Effective screening and recruitment are essential to the success of randomized clinical trials. This report is to describe key screening and recruitment strategies in a two site randomized clinical trial (RCT) conducted in community settings with a vulnerable chronically ill population and to suggest valuable approaches when planning trials. Differences between sites in a complex study with two considerably different environments (academic versus home care) and their participant pools presented challenges which required different screening and recruitment methods. A high level of communication between sites, creative problem solving and the ability to be flexible when problems were encountered were needed for successful screening and recruitment.

Fatigability disrupts cognitive processes' regulation of inflammatory reactivity in old age.

OBJECTIVE: High fatigability, a dysfunctional adaption to fatigue, may lead to difficulties performing otherwise regularly encountered cognitive activities and may be related to pro-inflammatory reactivity. The purpose of the study was to investigate the effect of fatigability on cognitive processes and inflammatory response after an acute cognitive stress task in older adults. METHODS: In an observational stress reactivity study conducted in a light- and temperature-controlled laboratory, we measured IL-6, self-reported acute fatigue, and frontally oriented cognitive processes in 55 community-dwelling individuals aged 75 years or older as part of a demanding set of cognitive tasks intended to induce stress. RESULTS: Subjects were classified into groups of low and high fatigability based on cluster analysis of their self-report acute fatigue before and after the cognitive tasks. The two clusters were comparable on levels of baseline IL-6 and cognitive processes; however, the high fatigability cluster had significantly higher levels of IL-6 response than the low fatigability cluster. After controlling for multiple covariates, fatigability moderated the relationship between speed of processing and IL-6 reactivity. Further exploratory analyses indicated significant adverse associations between speed of processing and attention and IL-6 reactivity in the group with low but not high fatigability. CONCLUSION: Although observational, these data are consistent with the notion that pro-inflammatory states in older adults might be reduced by improvements in cognitive processes. Because fatigability was associated with increased acute inflammatory response and disrupted the normal stress regulation provided by the cognitive processes, future randomized studies might examine whether fatigability alleviation reduces IL-6.

Perceived value of a urinary catheter self-management program in the home.

A long-term indwelling urinary catheter intervention was tested in a randomized trial that is described in this article. The perceived value of the intervention to the catheter users, one of the study's specific aims, was assessed at the end of their 12-month participation and is reported here. Study participants' responses, our findings, and implications for home healthcare are discussed.

Long-term urinary catheter users self-care practices and problems.

AIMS AND OBJECTIVES: To characterise a sample of 202 adult community-living long-term indwelling urinary catheter users, to describe self-care practices and catheter problems, and to explore relationships among demographics, catheter practices and problems. BACKGROUND: Long-term urinary catheter users have not been well studied, and persons using the device indefinitely for persistent urinary retention are likely to have different patterns of catheter practices and problems. DESIGN: The study was a cross-sectional descriptive and exploratory analysis. METHODS: Home interviews were conducted with catheter users who provided information by self-reported recall over the previous two months. Data were analysed by descriptive statistics and tests of association between demographics, catheter practices and catheter problems. RESULTS: The sample was widely diverse in age (19-96 years), race and medical diagnosis. Urethral catheters were used slightly more often (56%) than suprapubic (44%), for a mean of six years (SD 7 years). Many persons were highly disabled, with 60% having difficulty in bathing, dressing, toileting and getting out of the bed; 19% also required assistance in eating. A high percentage of catheter problems were reported with: 43% experiencing leakage (bypassing of urine), 31% having had a urinary tract infection, 24% blockage of the catheter, 23% catheter-associated pain and 12% accidental dislodgment of the catheter. Treatments of catheter-related problems contributed to additional health care utilisation, including extra nurse or clinic visits, trips to the emergency department or hospitalisation. Symptoms of catheter-associated urinary tract infections were most often related to changes in the colour or character of urine or generalised symptoms. CONCLUSIONS: Catheter-related problems contribute to excess morbidity and health care utilisation and costs. RELEVANCE TO CLINICAL PRACTICE: More research is needed in how to minimise catheter-associated problems in long-term catheter users. Information from this study could help inform the development of interventions in this population.

Internet recruitment and retention for a 6 months' longitudinal study.

PURPOSE: To examine factors influencing recruitment and retention of study participants in a longitudinal study. METHODS: After completion of a longitudinal (6 months) study of long-term indwelling urinary catheter users, three types of data were analyzed: number of problems with data entry into an online survey, number of reminders sent by study staff to participants, and number and nature of e-mail contacts between participants and study staff and among study staff regarding the study. CONCLUSIONS: The Internet can be used effectively for research, especially involving small, specialized populations. In order to retain study subjects and obtain complete and accurate data, study staff must be closely involved and responsive to participants' issues, and technical support staff must be readily available and invested in the research project. CLINICAL RELEVANCE: Using the Internet to reach small, special, marginalized, or geographically dispersed populations for research is becoming common. Researchers need to know how best to recruit, support, and retain participants in Internet-based studies.
