Outcomes in work-related upper extremity and low back injuries: results of a retrospective study.

BACKGROUND: The outcomes of treatment for work-related injuries and illnesses are multidimensional and complex, but have rarely been explored in detail. This study was intended to provide information on a sample of workers representing a range of jobs and employers typical of the workers compensation system. METHODS: A mailed, self-report survey measuring multiple dimensions was conducted. Identified through the New Hampshire Division of Workers' Compensation First Report of Injury database, a sample of workers with injuries to their lower back (60%) or upper extremities (40%) a year prior to the study were surveyed. Response rate was 80% (N=169; upper extremity cases=70; low back cases=99). RESULTS: Most (82.8%) were working one year post-injury. Over half reported residual effects of the injury on work or activities of daily living. Many working subjects reported persistent injury-related anxiety and pain at the end of the work day, worse in those with low back pain compared to those with upper extremity injuries. Almost 40% of those who returned to work suffered a reinjury. Forty-four percent of respondents suffered significant injury-related financial problems, which were worse in those who had been out of work for longer periods. CONCLUSIONS: Occupational musculoskeletal injuries do result in significant, long-term adverse physical, economic, and psychological consequences, as demonstrated in self-reported surveys.

Work-related upper-extremity disorders: prospective evaluation of clinical and functional outcomes.

The purpose of this study was to describe the demographic, vocational, medical, workplace, and psychosocial characteristics of patients treated for work-related upper-extremity disorders, to document treatment patterns in a community-practice setting, and to determine which of these factors predicts subsequent employment and functional status outcomes. A questionnaire was administered by mail or telephone to 112 patients seen at the University of Massachusetts Occupational Upper Extremities Disorders Clinic and included measures of disease-specific functional status, pain, reactions to pain, employer-employee relations, and number and type of interventions used to treat the disorder. Results were compared with baseline data obtained, on average, 16 months prior to follow-up. Of the original cohort (n = 124), 112 participated in the prospective study. Although most patients reported improvement in pain severity, fear of pain, life situation, and functional status, there was little change in employment status. Patients' self-reported intentions of return to work at baseline did not predict work status at follow-up. In general, those who were employed at baseline remained employed, had a greater reduction in symptom severity over time, and were significantly more likely to report improvement in their problem than those who were unemployed. The efficacy of various interventions was examined by type, mix, and intensity (number of different interventions undergone by the patient). No positive relationship was found between these measures and employment status, self-reported change in the problem, or self-reported improvement in functional status. Significant negative relationships were found between surgery, psychotherapeutic interventions, and outcomes. This was likely to have occurred because of a selection bias toward the more chronic and severely disabled patients for these treatments. However, the relative ineffectiveness of such intensive interventions as surgery in improving the work and health status of chronically symptomatic work-related upper-extremity patients cannot be overlooked. The findings suggest that more emphasis be placed on interventions aimed at resolving differences between employers and injured employees. More careful selection of patients for expensive and invasive procedures is recommended.

Outcome measures after standardized pain management strategies in postoperative patients in the neonatal intensive care unit.

Written guidelines based on current research on infant pain assessment and management were developed by an interdisciplinary team in a neonatal intensive care unit of a regional medical center. Charts for infants who had undergone abdominal surgery were reviewed to compare patient outcomes before and after use of this pain management protocol. With the standardization of pain management strategies, the following improvements were noted: decreased length of time to extubation, decreased length of stay, better fluid management, and reduced side effects of narcotics. Additional benefits included improved pain management documentation, decreased cost, and decreased nursing time.

Outcomes research and the allied health professional.

Outcomes research has become increasingly important in recent years in evaluating the quality of health care and in making policy and clinical decisions. There has been a growing awareness of the need to adapt outcomes research methods for the assessment of treatments provided by the allied health research and professional communities. This is imperative due to the growth of managed care plans and the need for professional legitimization and separate reimbursement of services. This article provides an overview of the history of the outcomes research movement, with specific reference to federal government involvement. Differences between efficacy and effectiveness research are delineated, the problems in undertaking outcomes studies to evaluate allied health-provided treatments are discussed, and strategy for increasing the use of outcomes research in the assessment of allied health treatments is given.

Synergistic inhibition of metabolic cooperation by oleic acid or 12-0-tetradecanoylphorbol-13-acetate and dichlorodiphenyltrichlorethane (DDT) in Chinese hamster V79 cells: implication of a role for protein kinase C in the regulation of gap junctional intercellular communication.

The effects of TPA and/or DDT and oleic acid and/or DDT on gap junction-mediated intercellular communication (i.e. metabolic cooperation) between Chinese hamster V79 cells was examined. Addition of TPA, DDT or oleic acid alone to cocultures of 6-thioguanine-resistant (6-TGR) and 6-thioguanine-sensitive (6-TGS) V79 cells significantly increased the recovery of 6-TGR cells indicating inhibition of metabolic cooperation. In the presence of TPA and DDT or oleic acid and DDT the observed recovery of 6-TGR cells was significantly greater than the expected (calculated) additive 6-TGR cell recovery. No synergistic increases in 6-TGR cell recovery were observed when co-cultures of V79 cells were exposed to dieldrin and DDT. These results indicate that TPA and DDT or oleic acid and DDT can act synergistically to inhibit metabolic cooperation. These data suggest a role for protein kinase C in the regulation of gap junction-mediated intercellular communication.
