Frequency and age effects of secondary health conditions in individuals with spinal cord injury: a scoping review.

Study design:Scoping review.Objectives:To gain a better understanding of the prevalence, course and association with age of secondary health conditions in individuals with spinal cord injury (SCI).Setting:Seattle, Washington, USA.Methods:We performed searches of electronic databases for studies published from 1986–2011 that provided information regarding the prevalence, course or associations with age and duration of secondary health conditions in individuals with SCI.Results:Ninety-two studies were included. The findings indicate that: (1) individuals with SCI experience a number of secondary health conditions, many of which occur at a higher rate in those with SCI than the normative population; (2) the most common conditions or symptoms are pain, bowel and bladder regulation problems, muscle spasms, fatigue, esophageal symptom and osteoporosis; (3) a number of conditions, including cardiovascular disease, diabetes, bone mineral density loss, fatigue and respiratory complications or infections, occur with higher frequency in older individuals or those with longer SCI duration, relative to younger individuals or those with shorter SCI duration; and (4) there is a marked lack of longitudinal research examining the natural course of health conditions in individuals aging with SCI.Conclusions:The findings support the conclusion that individuals with SCI show signs of ‘premature aging’ in different organ systems. Longitudinal research is needed to understand when problems are most likely to emerge, and to develop and test the efficacy of interventions to prevent these health conditions and their negative impact.

Communication and Aging

People with communication disorders form a diverse group with some experiencing long-standing disorders and others the onset of new disorders in old age. Regardless of age at onset, the burden of communication disorders is cumulative and has important implications for health care providers. Communication serves many roles for older people, not only establishing and maintaining social affiliations but also providing access to health care services. Health care providers should be aware of potential communication disorders and make provision for quiet environments, reading materials at appropriate literacy levels, and longer appointments for people with communication difficulties.

Training healthcare providers in patient–provider communication: What speech-language pathology and medical education can learn from one another

Background: While the field of speech-language pathology and medical education both provide training to improve the abilities of their students to communicate with patients, these fields rarely interact or collaborate with one another to maximise the effectiveness of this training. With a recent emphasis on the communication needs of patients with aphasia and other communication disorders in healthcare, and barriers these patients often face in accessing healthcare services, it has become increasingly important to review current research regarding patient–provider communication training, as well as what speech-language pathology and medical education can learn from one another in this area. Aims: The purpose of this literature review was (1) to examine the impact of communication disorders on patient–provider communication, (2) to identify gaps in current patient–provider communication training in medical education that speech-language pathology can help fill, and (3) to highlight innovations in medical education that may enhance the clinical training of speech-language pathology students. Main Contributions: There is a significant body of research to demonstrate the effectiveness of patient–provider communication training in medical education. However, research and training in this area often neglects patients with aphasia and other communication disorders, who are more vulnerable to medical errors and poorer health outcomes than patients without communication disorders. Speech-language pathologists (SLPs) are uniquely qualified to train other healthcare providers in communication techniques to use with patients with communication disorders. The field of speech-language pathology can also benefit from using patient–provider communication frameworks and standardised patients to improve student training and service delivery for patients with communication disorders. Conclusions: Collaboration between speech-language pathology and medical education can help to ensure the highest-quality healthcare services are offered to the patients they serve.

Developing a scale of communicative participation: A cognitive interviewing study

Purpose. To revise and improve the instructions, candidate items and response format for a tool to measure communicative participation. Method. Cognitive interviewing techniques, designed to study the process that respondents use to answer survey questions, were used to test a bank of candidate items for a measure of communicative participation. Twelve participants with spasmodic dysphonia (SD), a neurologic condition characterized by voice and speech changes, were asked to complete a sample questionnaire and then were interviewed regarding the clarity of instructions, candidate items and response format. Analysis of the interviews was conducted using qualitative techniques and resulted in a series of modifications to the measurement tool. Results. Problems identified related to candidate items included inadequate context, double-barreled or ambiguous items, redundancy, unclear or generally confusing items, infrequent situations, and cultural sensitivity. Participants preferred response options that asked them to rate interference rather than other dimensions such as satisfaction. Conclusions. Subtle differences in items and response options make key differences in how participants interpret and make decisions about their responses. Rich contextual information is needed in order to respond to items that sample communicative participation. Participants preferred response options that capture the barriers that they experience when participating in everyday communication situations.

Review of secondary health conditions in postpolio syndrome: prevalence and effects of aging.

ObjectiveThis study sought to better understand the prevalence and the severity of secondary health conditions in individuals with postpolio syndrome (PPS) as well as the association between these conditions and aging. DesignA scoping literature review was conducted searching electronic databases for studies published from 1986 to 2011. The scoping review provided information regarding the prevalence and associations of secondary health conditions in PPS with age or other duration-related variables. ResultsThe findings indicate that (1) individuals with PPS experience a number of serious secondary health conditions; (2) the most common conditions or symptoms are fatigue, pain, respiratory and sleep complaints, and increased risk for falls; (3) reports of the associations between the frequency or the severity of conditions and age-related factors are variable, perhaps because of methodological inconsistencies between studies; and (4) there is a marked lack of longitudinal research examining the natural course of health conditions in people aging with PPS. ConclusionsLongitudinal research is needed to understand the course of health conditions and the impact of multiple secondary conditions in people aging with PPS. Efforts are also needed to develop and test the efficacy of interventions to prevent these secondary health conditions or reduce their negative impact.

Communicative Participation and Quality of Life in Head and Neck Cancer

Objective: The purpose of this study was to determine how a new self-report outcome measure of communicative participation, the Communicative Participation Item Bank (CPIB), related to disease- and discipline-specific quality of life (QOL) outcomes in a head and neck cancer (HNC) population. Methods: One hundred ninety-five individuals treated for HNC completed the CPIB, the University of Washington Quality of Life questionnaire (UW-QOL), and the Voice Handicap Index–10 (VHI-10). Results: Results revealed moderate QOL scores across the UW-QOL (mean scores: global QOL = 66; physical subscale = 70; social-emotional subscale = 73) and VHI-10 (mean = 16). Correlations between the CPIB and the UW-QOL scores were statistically significant (P < .001) but relatively weak (r = .37–.38). As hypothesized, a stronger correlation was found between the CPIB and the VHI-10 (r = −0.79; P < .001). Conclusion: Clinicians may consider adopting the CPIB to complement existing tools in assessing communication outcomes after HNC.

Variables associated with communicative participation in Parkinson’s disease and its relationship to measures of health-related quality-of-life

Abstract Purpose: Communication disorders associated with Parkinson’s disease (PD) often lead to restricted participation in life roles, yet there is a limited understanding of influencing factors and few quantitative measurement tools available. This study aimed to identify variables associated with communicative participation in PD and to examine the relationship between the Communicative Participation Item Bank (CPIB) and existing health-related quality-of-life (HRQoL) measures. Method: Self-report data from 378 participants with PD from the US and New Zealand were analysed. Data included responses to the CPIB, PD Questionnaire-8, sub-scales of the Global Health instrument from the Patient Reported Outcomes Measurement Information System (PROMIS) and additional self-report instruments. Result: Greater perceived speech disorder, lower levels of speech usage, fatigue, cognitive and emotional problems and swallowing difficulties were associated with lower levels of communicative participation. Participants’ age significantly influenced findings, interacting with country of residence, sex and speech usage. Scores on the CPIB were moderately correlated with HRQoL measures. Conclusion: Communicative participation in PD is complex and influenced by both demographic and disease-based variables, necessitating a broader view of the communicative experiences of those with PD. Measurement of communicative participation as a separate construct to existing HRQoL measures is recommended.

Endoscopic assessment of vocal fold movements during cough

Objectives: Little is known about the function of the true vocal folds (TVFs) during cough. The objective of this study was to determine the reliability of measuring TVF movements during cough and to obtain preliminary normative data for these measures. Methods: Sequential glottal angles associated with TVF adduction and abduction across the phases of cough were analyzed from laryngeal videoendoscopy records of 38 young healthy individuals. Results: The intraobserver and interobserver reliability of 3 experienced measurers was high (intraclass correlation of at least 0.97) for measuring sequential and maximum glottal angles. The TVF abduction velocity during expulsion was significantly higher than the precompression adduction velocity (p = 0.002), but there were no significant differences in maximum angle. No statistically significant differences were seen in maximum TVF angle and velocity when they were compared between the sexes and between the levels of cough strength. True vocal fold closure following expulsion occurred in 42% of soft coughs and in 57% of moderate to hard coughs. Conclusions: The TVF abduction angles during cough can be reliably measured from laryngeal videoendoscopy in young healthy individuals. The TVF movements are faster for expulsion abduction than for precompression adduction, but the extents of abduction are similar. To validly determine the cough phase duration, simultaneous measures of airflow are needed.

Variables Associated With Communicative Participation After Head and Neck Cancer

Importance For patients with head and neck cancer (HNC), communication difficulties often create substantial barriers in daily life, affecting a persons ability to return to work, establish or maintain relationships, or participate in everyday activities. Objective To examine variables significantly associated with communication in everyday activities, or communicative participation, in adult survivors of HNC. Design, Setting, and Participants In a cross-sectional study, from November 1, 2008, through March 18, 2011, participants completed questionnaires about specific experiences and symptoms associated with their health and communication. Seventeen variables were considered in association with communicative participation. Data were collected from adult survivors of HNC residing in a community. Participants completed questionnaires, in English, either online or using paper forms according to their preference. Participants were recruited through support groups, professional email lists, and professional contacts. Main Outcomes and Measures Communicative participation and predictor variables were measured using a variety of validated patient-report scales and demographic information. Multiple linear regression analysis was conducted with variables entered using a backward stepwise regression procedure. Variables with significant regression coefficients were retained in the model and reported as change in R2. Results One hundred ninety-seven adults (121 males and 76 females; mean age, 61.5 years) participated, all at least 6 months posttreatment of HNC with no additional medical conditions affecting speech. The final model contained 4 significant variables (R2 = 0.462): self-rated speech severity, cognitive function, laryngectomy status, and time since diagnosis. Better communicative participation was associated with less severe speech and cognitive problems; together, these 2 variables explained 42% of the variance in the model (self-rated speech severity, R2 = 0.227, and cognitive function, R2 = 0.193 [0.227 + 0.193 = 0.420 = 42%]). To a lesser extent, better communicative participation also was associated with not having undergone a total laryngectomy surgical procedure (R2 = 0.035) and longer time since diagnosis (R2 = 0.007); full model: R2 = 0.462, P < .001; regression coefficients [SE]: self-rated speech severity 0.551 [0.065], P < .001, R2 = 0.227; cognitive function 0.063 [0.011], P < .001, R2 = 0.193; laryngectomy status 0.285 [0.117], P = .02; and time since diagnosis 0.015 [0.006], P = .02. Conclusions and Relevance These results suggest that communicative participation in adults with HNC is associated with self-rated speech severity, cognitive function, whether or not a person has undergone total laryngectomy, and time since diagnosis. Clinicians can use these results to inform their practice in pretreatment counseling, patient education, and rehabilitation for survivors of HNC.

Communicative participation restrictions in multiple sclerosis: Associated variables and correlation with social functioning

UNLABELLED Individuals with multiple sclerosis (MS) are at risk for communication problems that may restrict their ability to take participation in important life roles such as maintenance of relationships, work, or household management. The aim of this project is to examine selected demographic and symptom-related variables that may contribute to participation restrictions. This examination is intended to aid clinicians in predicting who might be at risk for such restrictions and what variables may be targeted in interventions. Community-dwelling adults with MS (n=216) completed a survey either online or using paper forms. The survey included the 46-item version of the Communicative Participation Item Bank, demographics (age, sex, living situation, employment status, education, and time since onset of diagnosis of MS), and self-reported symptom-related variables (physical activity, emotional problems, fatigue, pain, speech severity, and cognitive/communication skills). In order to identify predictors of restrictions in communicative participation, these variables were entered into a backwards stepwise multiple linear regression analysis. Five variables (cognitive/communication skills, speech severity, speech usage, physical activity, and education) were statistically significant predictors of communication participation. In order to examine the relationship of communicative participation and social role variables, bivariate Spearman correlations were conducted. Results suggest only a fair to moderate relationship between communicative participation and measures of social roles. Communicative participation is a complex construct associated with a number of self-reported variables. Clinicians should be alert to risk factors for reduced communicative participation including reduced cognitive and speech skills, lower levels of speech usage, limitations in physical activities and higher levels of education. LEARNING OUTCOMES The reader will be able to: (a) describe the factors that may restrict participation in individuals with multiple sclerosis; (b) list measures of social functioning that may be pertinent in adults with multiple sclerosis; (c) discuss factors that can be used to predict communicative participation in multiple sclerosis.
