Development and Validation of Person-Centered Cut-Points for the Figure-of-8-Walk Test of Mobility in Community-Dwelling Older Adults.

ABSTRACT:

Background

The Figure-of-8-Walk test (F8WT) is a performance measure of the motor skill of walking. Unlike walking speed over a straight path, it captures curved path walking, which is essential to real-world activity, but meaningful cut-points have yet to be developed for the F8WT.

Methods

A secondary analysis of 421 community-dwelling older adults (mean age 80.7 ± 7.8), who participated in a community-based exercise clinical trial, was performed. Area under receiver operating characteristic curves (AUROCC) were calculated using baseline data, with F8WT performance discriminating different self-reported global mobility and balance dichotomies. Cut-points for the F8WT were chosen to optimize sensitivity and specificity. For validation, F8WT cut-points were applied to postintervention F8WT data. Participants were called monthly for 12 months after intervention completion to record self-reported incident falls, emergency department visits, and hospitalizations; risks of the outcomes were compared between those who performed well and poorly on the F8WT.

Results

F8WT performance times of ≤9.09 seconds and ≤9.27 seconds can discriminate those with excellent (sensitivity = 0.647; specificity = 0.654) and excellent/very good global mobility (sensitivity = 0.649; specificity = 0.648), respectively. A total number of steps ≤17 on the F8WT can discriminate those with excellent/very good/good global balance (sensitivity = 0.646; specificity = 0.608). Compared to those who performed poorly, those who performed well had a lower incidence of negative outcomes: F8WT time ≤9.09 seconds = 46%-59% lower; F8WT time ≤9.27 seconds = 46%-56% lower; F8WT steps ≤17 = 44%-50% lower.

Conclusions

Clinicians may consider these preliminary cut-points to aid in their clinical decision making, but further study is needed for definitive recommendations.

Project description:BackgroundAt a time when the world's population is aging, one of the most important challenges for the healthcare field is to control the decline of the musculoskeletal system. This decline consists of a reduction in muscle mass and function, which is called sarcopenia and is associated with adverse health outcomes. Although there has been an increase in the number of publications on sarcopenia and its consequences, the reported prevalence varies widely, since these depend on the characteristics of the population studied, the definitions found in the literature and the cut-off points adopted. In this perspective, the heterogeneity in the classification and the different reference values has a critical impact on the epidemiology of sarcopenia, since neither the procedures, the components and the cut-off points are consistent.ObjectivesTo develop cut-off points for the screening of sarcopenia in community-dwelling older people residents in the northeast of Brazil and compare the prevalences between the values defined by the consensus and the values of the population studied.MethodsCommunity-dwelling older men and women living in three cities in the countryside of Rio Grande do Norte were evaluated. Cutoff points were defined for the variables used to screen for sarcopenia (handgrip strength, SMI, gait speed and SPPB) using the 20th percentile of their population distributions.ResultsThe sample was composed of 1,290 older people (62.5% female and 37.5% male), with an average of 69.5 (± 6.05) years of age. Regarding the cutoff points, the handgrip values were defined as 25.3 kg and 16 kg for men and women, respectively. Considering the SMM adjusted according to their height, the values of 7.88 kg/m2 were adopted for men and 5.52 kg/m2 for women. When adjusting by BMI we obtained 0.73 kg/BMI for men and 0.41 kg/BMI for women. For gait speed it was defined 0.71 m/s for men and 0.63 m/s for women. In the case of SPPB, the result was the same for both genders (≤8). When applying the values found in the studied population, a variation in prevalence was observed for both men and women, depending on the cut-off points and consensus used.ConclusionThe cutoff values found in our population were lower than those adopted by international consensus (EWGSOP2, IWGS and FNIH), except for HGS in woman and SMI/m2 for men. Therefore, using specific cutoff points for different populations can provide an accurate assessment of the presence of sarcopenia and better target health prevention strategies for the older people living in the community.

Project description:ObjectiveMedication abortions now make up the majority of abortions in the US, with new service delivery models such as telehealth; however, it is unclear how this may impact patient experiences. The objective of the study is to adapt and validate a person-centered abortion care (PCAC) scale for medication abortions that was developed in a global South context (Kenya) for use in the United States.Study designThis study includes medication abortion patients from a hospital-based clinic who had one of two modes of service delivery: (1) telemedicine with no physical exam or ultrasound; or (2) in-person with clinic-based exams and ultrasounds. We conducted a sequential approach to scale development including: (1) defining constructs and item generation; (2) expert reviews; (3) cognitive interviews (n = 12); (4) survey development and online survey data collection (N = 182, including 45 telemedicine patients and 137 in-person patients); and (5) psychometric analyses.ResultsExploratory factor analyses identified 29-items for the US-PCAC scale with three subscales: (1) Respect and Dignity (10 items), (2) Responsive and Supportive Care (nine items for the full scale, one additional mode-specific item each for in-person and telemedicine), and (3) Communication and Autonomy (10 items for the full scale, one additional item for telemedicine). The US-PCAC had high content, construct, and criterion validity. It also had high reliability, with a standardized alpha for the full 29-item US-PCAC scale of 0.95. The US-PCAC score was associated with overall satisfaction.ConclusionThis study found high validity and reliability of a newly-developed person-centered abortion care scale for use in the US. As medication abortion provision expands, this scale can be used in quality improvement efforts.ImplicationsThis study found high validity and reliability of a newly-developed person-centered care scale for use in the United States for in-person and telemedicine medication abortion.

Project description:BackgroundThe concept of quality in health care has evolved, placing greater importance on the patient's needs, culture, and social context, as well as their participation in clinical decision-making, as highlighted by Mead and Bower's Person-Centered Care Model. The aim of the present study was to design and validate an instrument to assess the extent to which healthcare services provided by PEMEX (Petróleos Mexicanos) offer person-centered care according to user perceptions.MethodsThe first phase comprised the development of 57 items based on the analysis of responses from an open-ended questionnaire administered to 30 users of Pemex healthcare services. This questionnaire was designed considering the four factors of the person-centered care model, however, the high correlation between the 4 factors (i.e., r ≥ .80) indicated an overfactoring effect and consequently an increase in the risk of overfitting. Therefore, an exhaustive analysis of the instrument was performed, starting with the review of the individual behavior of each item, and carrying out exploratory and confirmatory factor analysis. Using a sample of 330 individuals, an exploratory factor analysis was perfomed. Afterward, a confirmatory factorial analysis was carried out with 335 participants. Finally, a new confirmatory factorial analysis included 130 participants due to the refinements made in the previous phase. Internal consistency was assessed using Cronbach's α and McDonald's ω at every phase.ResultsThe exploratory factor analysis retained 35 items in a single factor that accounted for 49% of the variance with an internal consistency of Cronbach's α and McDonald's ω = 0.97. Because the factorial structure by confirmatory factorial analysis was unsatisfactory, the initial model was refined, leading to the retention of 11 items and a final model with adjustment index of χ2 = 127.53, χ2/gl = 2.89, RMSEA = 0.07, IC RMSEA 0.06 to 0.09, TLI = 0.95 and CFI = 0.96, with an internal consistency of Cronbach's α and McDonald's ω = 0.93. Due to the refinements, a new confirmatory factorial analysis was conducted with suitable goodness-of-fit criteria in most items (χ2 = 151.44, χ2/gl = 3.43, RMSEA = 0.13, IC RMSEA 0.11 to 0.16, TLI = 0.93 and CFI = 0.94), resulting in a Cronbach's α and McDonald's ω = 0.98.ConclusionsThe instrument exhibits suitable psychometric properties to be employed to measure the degree to which medical care is patient centered. This instrument represents a strategy for promoting an innovative healthcare model.

Project description:BackgroundWomen's childbirth experience of interpersonal care is a significant aspect of quality of care. Due to the lack of a reliable Cambodian version of a measurement tool to assess person-centered maternity care, the present study aimed to adapt the "Person-Centered Maternity Care (PCMC) scale" to the Cambodian context and further determine its psychometric properties.MethodsThe PCMC scale was translated into Khmer using the team translation approach. The Khmer version of PCMC (Kh-PCMC) scale was pretested among 20 Cambodian postpartum women using cognitive interviewing. Subsequently, the Kh-PCMC scale was administered in a survey with 300 Cambodian postpartum women at two governmental health facilities. According to the COnsensus-based Standards for the Selection of health status Measurement Instruments (COSMIN) standard, we performed psychometric analysis, including content validity, construct validity, criterion validity, cross-cultural validity, and internal consistency.ResultsThe preliminary processes of Kh-PCMC scale development including cognitive interviewing and expert review ensured appropriate levels of content validity and acceptable levels of cross-cultural validity of the Kh-PCMC scale with four-point frequency responses. The Scale-level Content Validity Index, Average (S-CVI/Avg) of 30-item Kh-PCMC scale was 0.96. Twenty items, however, performed optimally in the psychometric analysis from the data in Cambodia. The 20-item Kh-PCMC scale produced Cronbach's alpha of 0.86 for the full scale and 0.76-0.91 for the subscales, indicating adequately high internal consistency. Hypothesis testing found positive correlations between the 20-item Kh-PCMC scale and reference measures, which implies acceptable criterion validity.ConclusionsThe present study produced the Kh-PCMC scale that enables women's childbirth experiences to be quantitatively measured. The Kh-PCMC scale can identify intrapartum needs from women's perspectives for quality improvement in Cambodia. However, dynamic changes in and diverse differences of cultural context over time across provinces in Cambodia require the Kh-PCMC scale to be regularly reexamined and, when needed, to be further adjusted.

Project description:BackgroundMotoric cognitive risk (MCR) syndrome is a predementia syndrome characterized by subjective cognitive complaints and slow gait in the absence of dementia and mobility disability. Although past research has suggested that personality traits could play a significant role in the onset and progression of MCR among older adults, the exact relationships between specific personality profiles and MCR remain unclear. This study aimed to examine the relationship between personality profiles and MCR among community-dwelling older adults.MethodsA cross-sectional study was conducted from March 2021 to January 2022. Personality traits, including openness, extraversion, agreeableness, conscientiousness and neuroticism, were measured using the 40-item brief version of the Chinese Big Five Inventory. The Latent profile analysis was used to identify personality profiles among these older adults who shared similar patterns of personality traits. The Lanza, Tan, and Bray's approach was employed to investigate the personality profile-specific differences in MCR prevalence. Furthermore, a stepwise multinomial logistic regression revealed unique population characteristics for different personality profiles.ResultsA total of 538 eligible participants were included in this study. The mean age was 73.25 years (SD = 9.0) and 62.50% were females. This study identified four distinct personality profiles: the resilient, ordinary, reserved, and anti-resilient profiles. The resilient profile exhibited the lowest prevalence of MCR (mean = 6%, SE = 0.024), whereas the anti-resilient profile had the highest (mean = 20.3%, SE = 0.043). The prevalence of MCR differed among personality profiles (overall χ2 = 14.599, p = 0.002). Personality profile membership was characterized by different population characteristics. Notably, the anti-resilient profile was association with symptoms of depression (OR = 28.443, 95%CI = 11.095-72.912), while the reserved profile was linked with advanced age (OR = 1.031, 95%CI = 1.003-1.061). Overall, a low education level and poor sleep quality were the robust attribution factors.ConclusionsThis study revealed that personality profiles may assist in identifying older adults at greater risk of MCR. Increased awareness and management of personality profiles may contribute to the prevention of MCR.

Project description:BackgroundPerson-centered care (PCC) is an important concept in many countries' national guidelines and dementia plans. Key intervention categories, i.e., a taxonomy of person-centered (PC)-interventions, to provide person-centered dementia care, are difficult to identify from literature.ObjectiveThis systematic review aimed to identify and categorize published PC-interventions into key intervention categories to guide the provision of person-centered dementia care.MethodsConduct of this systematic review followed Cochrane guidelines. A search of the dimensions 'Dementia', 'Person-Centered Care', and 'Intervention' combined was performed in PubMed, EMBASE, and Web of Science. Study selection was based on 2-stage screening against eligibility criteria, limited to controlled study designs. Information about interventions and outcomes was extracted into an "Effects Table". The identified PC-interventions were categorized in intervention categories to provide person-centered dementia care.ResultsSearches identified 1,806 records. 19 studies were included. These covered a range of psychosocial interventions, oftentimes multi-component interventions, which followed heterogeneous approaches. Studies were conducted in long-term care/hospital settings. Nine key intervention categories were identified: social contact, physical activities, cognitive training, sensory enhancement, daily living assistance, life history oriented emotional support, training and support for professional caregivers, environmental adjustments, and care organization.ConclusionOur findings provide a current overview of published PC-interventions in dementia, which followed heterogeneous approaches under the PCC-concept. The heterogeneity made it challenging to identify a well-defined concept of PCC and common key intervention categories. An effectiveness-evaluation of "PC" - including "relationship-centered"-interventions may be valuable, to assess whether an explicit focus on relationships around PCC-interventions yields an added benefit.Prospero-idCRD42021225084.
