Accuracy of self-reports of mental health care utilization and calculated costs compared to hospital records.
ABSTRACT Assessments of service utilization is often based on self-reports. Concerns regarding the accuracy of self-reports are raised especially in mental health care. The purpose of this study was to analyze the accuracy of self-reports and calculated costs of mental health services. In a prospective cohort study in Germany, self-reports regarding psychiatric inpatient and day-care use collected by telephone interviews based on the Client Socio-Demographic and Service Receipt Inventory (CSSRI) as well as calculated costs were compared to computerized hospital records. The sample consisted of patients with mental and behavioral disorders resulting from alcohol (ICD-10 F10, n=84), schizophrenia, schizophrenic and delusional disturbances (F2, n=122) and affective disorders (F3, n=124). Agreement was assessed using the concordance correlation coefficient (CCC), mean difference (95% confidence intervals (CI)) and the 95% limits of agreement. Predictors for disagreement were derived. Overall agreement of mean total costs was excellent (CCC=0.8432). Costs calculated based on self-reports were higher than costs calculated based on hospital records (15 EUR (95% CI -434 to 405)). Overall agreement of total costs for F2 patients was CCC=0.8651, for F3 CCC=0.7850 and for F10 CCC=0.6180. Depending on type of service, measure of service utilization and costs agreement ranged from excellent to poor and varied substantially between individuals. The number of admissions documented in hospital records was significantly associated with disagreement. Telephone interviews can be an accurate data collection method for calculating mean total costs in mental health care. In the future more standardization is needed.

ABSTRACT: Eccentric (ECC) exercise is classically used to improve muscle strength and power in healthy subjects and athletes. Due to its specific physiological and mechanical properties, there is an increasing interest in employing ECC muscle work for rehabilitation and clinical purposes. Nowadays, ECC muscle actions can be generated using various exercise modalities that target small or large muscle masses with minimal or no muscle damage or pain. The most interesting feature of ECC muscle actions is to combine high muscle force with a low energy cost (typically 4- to 5-times lower than concentric muscle work) when measured during leg cycle ergometry at a similar mechanical power output. Therefore, if caution is taken to minimize the occurrence of muscle damage, ECC muscle exercise can be proposed not only to athletes and healthy subjects, but also to individuals with moderately to severely limited exercise capacity, with the ultimate goal being to improve their functional capacity and quality of life. The first part of this review article describes the available exercise modalities to generate ECC muscle work, including strength and conditioning exercises using the body's weight and/or additional external loads, classical isotonic or isokinetic exercises and, in addition, the oldest and newest specifically designed ECC ergometers. The second part highlights the physiological and mechanical properties of ECC muscle actions, such as the well-known higher muscle force-generating capacity and also the often overlooked specific cardiovascular and metabolic responses. This point is particularly emphasized by comparing ECC and concentric muscle work performed at similar mechanical (i.e., cycling mechanical power) or metabolic power (i.e., oxygen uptake, [Formula: see text]). In particular, at a similar mechanical power, ECC muscle work induces lower metabolic and cardiovascular responses than concentric muscle work. However, when both exercise modes are performed at a similar level of [Formula: see text], a greater cardiovascular stress is observed during ECC muscle work. This observation underlines the need of cautious interpretation of the heart rate values for training load management because the same training heart rate actually elicits a lower [Formula: see text] in ECC muscle work than in concentric muscle work. The last part of this article reviews the documented applications of ECC exercise training and, when possible, presents information on single-joint movement training and cycling or running training programs, respectively. The available knowledge is then summarized according to the specific training objectives including performance improvement for healthy subjects and athletes, and prevention of and/or rehabilitation after injury. The final part of the article also details the current knowledge on the effects of ECC exercise training in elderly populations and in patients with chronic cardiac, respiratory, metabolic or neurological disease, as well as cancer. In conclusion, ECC exercise is a promising training modality with many different domains of application. However, more research work is needed to better understand how the neuromuscular system adapts to ECC exercise training in order to optimize and better individualize future ECC training strategies.Sports Medicine 05/2013; · 5.32 Impact Factor

ABSTRACT: The aim of this study was to assess the economic cost of chronic pain among adolescents receiving interdisciplinary pain treatment. Information was gathered from 149 adolescents (ages 10-17) presenting for evaluation and treatment at interdisciplinary pain clinics in the United States. Parents completed a validated measure of family economic attributes, the Client Service Receipt Inventory, to report on health service use and productivity losses due to their child's chronic pain retrospectively over 12 months. Health care costs were calculated by multiplying reported utilization estimates by unit visit costs from the 2010 Medical Expenditure Panel Survey. The estimated mean and median costs per participant were $11,787 and $6,770 respectively. Costs were concentrated in a small group of participants, the top 5 % of those patients incurring the highest costs accounted for 30 % of total costs while the lower 75 % of participants accounted for only 34 % of costs. Total costs to society for adolescents with moderate to severe chronic pain were extrapolated to $19.5 billion annually in the U.S. The cost of childhood chronic pain presents a substantial economic burden to families and society. Future research should focus on predictors of increased health services use and costs in adolescents with chronic pain.The journal of pain : official journal of the American Pain Society. 06/2014;

ABSTRACT: Background Despite considerable research on substance-abuse placement matching, evidence is still inconclusive. The aims of this exploratory trial are to evaluate (a) the effects of following matching guidelines on health-care costs and heavy drinking, and (b) factors affecting the implementation of matching guidelines in the treatment of alcohol-dependent patients.MethodsA total of 286 alcohol-dependent patients entering one of four participating detoxification units and having no arrangements for further treatment will be recruited. During the first week of treatment, all patients will be administered Measurements in the Addictions for Triage and Evaluation (MATE), European Quality of Life-Five Dimensions health status questionnaire (EQ-5D), and the Client Socio-Demographic and Service Receipt Inventory¿European Version (CSSRI-EU). Patients who are randomly allocated to the intervention group will receive feedback regarding their assessment results, including clear recommendations for subsequent treatment. Patients of the control group will receive treatment as usual and, if requested, global feedback regarding their assessment results, but no recommendations for subsequent treatment. At discharge, treatment outcome and referral decisions will be recorded. Six months after discharge, patients will be administered MATE-Outcome, EQ-5D, and CSSRI-EU during a telephone interview.DiscussionThis trial will provide evidence on the effects and costs of using placement-matching guidelines based on a standardized assessment with structured feedback in the treatment of alcohol-dependent patients. A process evaluation will be conducted to facilitate better understanding of the relationship between the use of guidelines, outcomes, and potential mediating variables.Trial registrationGerman Clinical Trials Register DRKS00005035.
