Predictive factors of adherence to frequency and duration components in home exercise programs for neck and low back pain: an observational study

BackgroundEvidence suggests that to facilitate physical activity sedentary people may adhere to one component of exercise prescriptions (intensity, duration or frequency) without adhering to other components. Some experts have provided evidence for determinants of adherence to different components among healthy people. However, our understanding remains scarce in this area for patients with neck or low back pain. The aims of this study are to determine whether patients with neck or low back pain have different rates of adherence to exercise components of frequency per week and duration per session when prescribed with a home exercise program, and to identify if adherence to both exercise components have distinct predictive factors.MethodsA cohort of one hundred eighty-four patients with chronic neck or low back pain who attended physiotherapy in eight primary care centers were studied prospectively one month after intervention. The study had three measurement periods: at baseline (measuring characteristics of patients and pain), at the end of physiotherapy intervention (measuring characteristics of the home exercise program) and a month later (measuring professional behaviors during clinical encounters, environmental factors and self-efficacy, and adherence behavior).ResultsAdherence to duration per session (70.9% ± 7.1) was more probable than adherence to frequency per week (60.7% ± 7.0). Self-efficacy was a relevant factor for both exercise components (p < 0.05). The total number of exercises prescribed was predictive of frequency adherence (p < 0.05). Professional behaviors have a distinct influence on exercise components. Frequency adherence is more probable if patients received clarification of their doubts (adjusted OR: 4.1; p < 0.05), and duration adherence is more probable if they are supervised during the learning of exercises (adjusted OR: 3.3; p < 0.05).ConclusionWe have shown in a clinic-based study that adherence to exercise prescription frequency and duration components have distinct levels and predictive factors. We recommend additional study, and advise that differential attention be given in clinical practice to each exercise component for improving adherence.

Self-Management of Chronic Neck and Low Back Pain and Relevance of Information Provided During Clinical Encounters: An Observational Study

UNLABELLED Escolar-Reina P, Medina-Mirapeix F, Gascón-Cánovas JJ, Montilla-Herrador J, Valera-Garrido JF, Collins SM. Self-management of chronic neck and low back pain and relevance of information provided during clinical encounters: an observational study. OBJECTIVE To assess the relative influence of information provided during physical therapy on a patients adherence to self-management strategies in relation to other predictors of adherence (patient and pain characteristics, use of self-management strategies before intervention). DESIGN A longitudinal observational study of the relationship between the information provided during physical therapy and adherence to self-management strategies. SETTING Data came from a clinical-based population in 8 primary health care centers. PARTICIPANTS Patients (N=184) with chronic neck or low back pain (77% under the age of 59y) were surveyed at the beginning and 1 month after completion of physical therapy. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Specific and overall adherence to 2 types of strategies: (1) nonpharmacologic pain management strategies, and (2) neck/back care in activities of daily life. RESULTS Adherence to strategies of nonpharmacologic self-management of pain was more probable when patients received information explaining the effectiveness of the self-management strategies (adjusted odds ratio [AOR]=10.1; P<.05) and information about their illness (AOR=3.4; P<.05) during clinical encounters. Information provided by the physical therapist did not have any influence on the adherence to neck/back care in activity of daily life (P>.05). CONCLUSIONS Information provided during clinical encounters is associated with adherence to different kinds of self-management strategies. While further study is required, it is suggested that more attention be given to clinical practice strategies for improving adherence to self-management of chronic pain.

Is patient satisfaction and perceived service quality with musculoskeletal rehabilitation determined by patient experiences

Objective: To assess the relationships between patient experiences and two overall evaluations – satisfaction and service quality – in outpatient rehabilitation settings. Design: A cross-sectional, self-reported survey carried out in the year 2009. Setting: Three outpatient rehabilitation units belonging to Spanish hospitals located in Barcelona, Madrid and Seville. Subjects: Four hundred and sixty-five outpatients (response rate 90%) mean age 39.4 (SD = 11.9) years. Main measures: Self-reported experiences on aspects of care, participants’ perception of service quality, satisfaction with care, socio-demographic and health characteristics. Results: Satisfaction and service quality were highly correlated (rho = 0.72, P< 0.001). Two multivariate logistic regression models using satisfaction and service quality (with adjusted R2 31.5% and 37.1%, respectively) indicated that patients’ experiences and global rating of health improvement have more effect on those evaluations than socio-demographic characteristics. Mean satisfaction was 8.9 (SD = 1.2), and 88% of respondents described high service quality. However, nearly 25% of the respondents who reported high-quality evaluations also indicated a problem score of more than 50% in almost all aspects of care studied. Conclusions: Satisfaction and service quality provide a poor indicator of patients’ experiences. Both are two proxies but distinct constructs in rehabilitation care. Besides, not all problems encountered by patients are equally important to them.

Mobility Activities Measurement for Outpatient Rehabilitation Settings

OBJECTIVE To investigate the factor structure and scale properties of items underlying the mobility activities subdomains of the International Classification of Functioning, Disability and Health (ICF). DESIGN A cross-sectional self-report-based psychometric study. SETTING Outpatient rehabilitation settings (N=3) in 3 urban areas of Spain. PARTICIPANTS Convenience sample of 615 patients with musculoskeletal conditions (mean age, 38.1y) participating in an active physiotherapy program. INTERVENTIONS Not applicable. MAIN OUTCOMES MEASURES A 22-item Mobility Activities Measure by using a self-report questionnaire that assessed whether patients had limitations on daily activities across major ICF categories of mobility subdomains. Factor analysis, tests of item scaling, internal consistency reliability analysis, Rasch item response theory modeling, and modified parallel analysis were used. RESULTS Initial exploratory factor analysis results for each ICF subdomain produced a total of 5 distinct and interpretable factors or dimensions: changing and maintaining body position involving sitting and/or lying; changing and maintaining body position involving standing up; carrying, moving, and handling objects using the hand and shoulder; carrying, moving, and handling objects using the hand and/or forearm; and walking and moving. Dimensionality of these 5 factors was verified by using confirmatory factor analyses and scaling assumptions were met for each dimension. Rasch scaling and modified parallel analysis supported the unidimensionality. CONCLUSIONS The Mobility Activities Measure is a promising new self-report measure of mobility activities as defined by the ICF. Information about Mobility Activities Measure items and dimensions from this study will be useful in the future operationalization and implementation of ICF.

RELIABILITY AND VALIDITY OF PATIENT REPORTS FOR PHYSICAL THERAPY QUALITY ASSESSMENT: AN EMPIRICAL ANALYSIS REGARDING THE USE OF EXERCISES FOR NECK PAIN IN SPAIN

OBJECTIVE To determine usefulness and reliability of patient reports as a data source on the use of exercises for neck pain in primary healthcare. DESIGN Survey research. SUBJECTS A total of 176 patients with mechanical neck pain, surveyed about their physical therapy experience. METHOD A questionnaire was constructed on the selection of exercises, instructions for carrying them out and follow-up provided by the physical therapist. The same items reported by the surveyed patients were also reviewed in the physical therapy record. We analysed the reliability and validity of the questionnaire, and used the valid information from the survey to estimate a total of 8 indicators on the quality of care provided. RESULTS Sensitivity of the items was high (>75%), suggesting that most of the recorded information could be provided by patients, and specificity was quite low, suggesting that they also provide relevant information that was not recorded. These results, particularly low specificity, were not homogeneous among items. Estimates for the indicators demonstrate room for improvement. CONCLUSION Patient reports could be useful as a complement to other sources of information for physical therapy quality assessment, and they can be reliable and valid substitutes for recorded data about specific aspects of the care provided.

Frailty is a predictive factor of readmission within 90 days of hospitalization for acute exacerbations of chronic obstructive pulmonary disease: a longitudinal study

Background: Readmission after hospital discharge is common in patients with acute exacerbations (AE) of chronic obstructive pulmonary disease (COPD). Although frailty predicts hospital readmission in patients with chronic nonpulmonary diseases, no multidimensional frailty measures have been validated to stratify the risk for patients with COPD. Aim: The aim of this study was to explore multidimensional frailty as a potential risk factor for readmission due to a new exacerbation episode during the 90 days after hospitalization for AE-COPD and to test whether frailty could improve the identification of patients at high risk of readmission. We hypothesized that patients with moderate-to-severe frailty would be at greater risk for readmission within that period of follow up. A secondary aim was to test whether frailty could improve the accuracy with which to discriminate patients with a high risk of readmission. Our investigation was part of a wider study protocol with additional aims on the same study population. Methods: Frailty, demographics, and disease-related factors were measured prospectively in 102 patients during hospitalization for AE-COPD. Some of the baseline data reported were collected as part of a previously study. Readmission data were obtained on the basis of the discharge summary from patients’ electronic files by a researcher blinded to the measurements made in the previous hospitalization. The association between frailty and readmission was assessed using bivariate analyses and multivariate logistic regression models. Whether frailty better identifies patients at high risk for readmission was evaluated by area under the receiver operator curve (AUC). Results: Severely frail patients were much more likely to be readmitted than nonfrail patients (45% versus 18%). After adjusting for age and relevant disease-related factors in a final multivariate model, severe frailty remained an independent risk factor for 90-day readmission (odds ratio = 5.19; 95% confidence interval: 1.26–21.50). Age, number of hospitalizations for exacerbations in the previous year and length of stay were also significant in this model. Additionally, frailty improved the predictive accuracy of readmission by improving the AUC. Conclusions: Multidimensional frailty predicts the risk of early hospital readmission in patients hospitalized for AE-COPD. Frailty improved the accuracy of discriminating patients at high risk for readmission. Identifying patients with frailty for targeted interventions may reduce early readmission rates.

Interobserver Reliability of Peripheral Muscle Strength Tests and Short Physical Performance Battery in Patients With Chronic Obstructive Pulmonary Disease: A Prospective Observational Study

OBJECTIVE To evaluate the interobserver reliability of the Short Physical Performance Battery (SPPB) and hand dynamometry when measuring isometric muscle strength in people with chronic obstructive pulmonary disease (COPD). DESIGN Reliability study. Each patient was assessed by a pulmonology physician and a physical therapist in 2 separate sessions 7 to 14 days apart (mean, 9.8±0.8d). Each rater was blinded to the others results. SETTING Pneumology unit of a public hospital. PARTICIPANTS Random sample of outpatients with stable COPD (N=30). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES SPPB and muscle strength (kg) using electronic handgrip and handheld dynamometers. Reliability was assessed with intraclass correlation coefficients (ICCs), standard error of measurement values, and Bland-Altman plots. ICCs were calculated for the SPPB summary score and for its 3 subscales. RESULTS The ICCs for the overall reliability of the SPPB summary score and for grip and quadriceps strength were .82 (95% confidence interval [CI], .62-.91), .97 (95% CI, .93-.98), and .76 (95% CI, .49-.88), respectively. The standard error of measurement values were .55 points, 1.30kg, and 1.22kg, respectively. The mean differences between the raters scores were near zero for grip strength and SPPB summary score measures. The ICCs for the SPPB subscales were .84 (95% CI, .66-.92) for the chair subscale, .75 (95% CI, .48-.88) for gait, and .33 (95% CI, -.42 to .68) for balance. CONCLUSIONS Interobserver reliability was good for quadriceps and handgrip dynamometry and for the SPPB summary score and its chair stand and gait speed subscales. Both pulmonary physicians and physical therapists can obtain and exchange the scores. Because the reliability of the balance subscale was questionable, it is better to use the SPPB summary score.

The accuracy with which the 5 times sit-to-stand test, versus gait speed, can identify poor exercise tolerance in patients with COPD: A cross-sectional study.

AbstractIdentifying those patients who underperform in the 6-minute walk test (6MWT <350 m), and the reasons for their poor performance, is a major concern in the management of chronic obstructive pulmonary disease.To explore the accuracy and relevance of the 4-m gait-speed (4MGS) test, and the 5-repetition sit-to-stand (5STS) test, as diagnostic markers, and clinical determinants, of poor performance in the 6MWT.We recruited 137 patients with stable chronic obstructive pulmonary disease to participate in our cross-sectional study. Patients completed the 4MGS and 5STS tests, with quantitative (in seconds) and qualitative ordinal data collected; the latter were categorized using a scale of 0 to 4. The following potential covariates and clinical determinants of poor 6MWT were collated: age, quadriceps muscle-strength (QMS), health status, dyspnea, depression, and airflow limitation. Area under the receiver-operating characteristic curve data (AUC) was used to assess accuracy, with logistic regression used to explore relevance as clinical determinants.The AUCs generated using the 4MGS and 5STS tests were comparable, at 0.719 (95% confidence interval [CI] 0.629–0.809) and 0.711 (95% CI 0.613–0.809), respectively. With ordinal data, the 5STS test was most accurate (AUC of 0.732; 95% CI 0.645–0.819); the 4MGS test showed poor discriminatory power (AUC <0.7), although accuracy improved (0.726, 95% CI 0.637–0.816) when covariates were included. Unlike the 4MGS test, the 5STS test provided a significant clinical determinant of a poor 6MWT (odds ratio 1.23, 95% CI 1.05–1.44).The 5STS test reliably predicts a poor 6MWT, especially when using ordinal data. Used alone, the 4MGS test is reliable when measured with continuous data.

Rates and predictors of depression status among caregivers of patients with COPD hospitalized for acute exacerbations: a prospective study

Background Hospitalization is common for acute exacerbation of COPD, but little is known about its impact on the mental health of caregivers. Objective The aim of this study was to determine the rates and predictors of depressive symptoms in caregivers at the time of hospitalization for acute exacerbation of COPD and to identify the probability and predictors of subsequent changes in depressive status 3 months after discharge. Materials and methods This was a prospective study. Depression symptoms were measured in 87 caregivers of patients hospitalized for exacerbation at hospitalization and 3 months after discharge. We measured factors from four domains: context of care, caregiving demands, caregiver resources, and patient characteristics. Univariate and multivariate multiple logistic regressions were used to determine the predictors of depression at hospitalization and subsequent changes at 3 months. Results A total of 45 caregivers reported depression at the time of hospitalization. After multiple adjustments, spousal relationship, dyspnea, and severe airflow limitation were the strongest independent predictors of depression at hospitalization. Of these 45 caregivers, 40% had a remission of their depression 3 months after discharge. In contrast, 16.7% of caregivers who were not depressive at hospitalization became depressive at 3 months. Caregivers caring >20 hours per week for patients with dependencies had decreased odds of remission, and patients having dependencies after discharge increased the odds of caregivers becoming depressed. Conclusion Depressive symptoms are common among caregivers when patients are hospitalized for exacerbation of COPD. Although illness factors are determinants of depression at hospitalization, patient dependence determines fluctuations in the depressive status of caregivers.

Mobility limitations related to reduced pulmonary function among aging people with chronic obstructive pulmonary disease

Background Chronic obstructive pulmonary disease (COPD) is a major cause of disability. We aimed to analyse the impact of reduced pulmonary function on non-respiratory impairments and mobility activity limitations in an elderly population with COPD and to elucidate which specific limitations on mobility are related to reduced pulmonary function Methods Cross-sectional study of 110 patients with COPD, recruited from public and university hospital. The effect of impaired pulmonary function on the risk of non-respiratory impairments and mobility limitations was analysed using validated measures, including: the 6-Minute Walk Test (6MWT), skeletal muscle strength, the Short Physical Performance Battery (SPPB), and self-reported mobility questionnaire. Multivariate analysis was used to control for confounders such as age, sex, height, education, and cigarette smoking. Results Greater impairment of pulmonary function was associated with less distance walked during the 6MWT, poorer SPPB scores, and greater risk of self-reported mobility limitations (p<0.05). Lower forced expiratory volume in 1 s was also associated with a greater risk of limitations in carrying items under 10 pounds (4.54 kg), walking alone up and down a flight of stairs, and walking two or three neighbourhood blocks. There was no clear statistical relationship between pulmonary function impairment and skeletal muscle strength. Conclusions Impaired pulmonary function was associated with the 6MWT score and limitations on performance-based and self-reported mobility activities, but not with skeletal muscle strength among elderly COPD patients.
