Klein M, Wobbe-Ribinski S, Buchholz A, Nienhaus A, Schablon A. Nurse-work instability and incidence of sick leave - results of a prospective study of nurses aged over 40. J Occup Med Toxicol 2018; 13:31. [PMID: 30323855 PMCID: PMC6173869 DOI: 10.1186/s12995-018-0212-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2017] [Accepted: 09/17/2018] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND The Nurse Work Instability Scale (Nurse-WIS) is an occupation-specific instrument that ascertains "work instability," the interval before restricted work ability or prolonged sick leave occurs. The objective of the study was to assess if nurses with a high risk baseline-score in the Nurse-WIS take longer periods of sick leave due to musculoskeletal diseases and/or psychological impairments than other nurses. METHODS A total of 4500 nurses randomly selected from one of the largest health insurance funds in Germany (DAK-Gesundheit) were invited by letter to participate in the study. The participants answered a questionnaire at baseline and gave consent to a transfer of data concerning sick leave during the twelve months following completion of the questionnaire from the health insurance to the study centre. Sensitivity, specificity and positive and negative predictive values (PPV and NPV) for long-term sick leave were calculated. In order to analyze the association between the Nurse-WIS and sick leave during follow-up, a multiple ordinal logistic model (proportional odds model) was applied. RESULTS A total of 1592 nurses took part in the study (response 35.6%). No loss of follow-up occurred. The number of nurses with a high score (20-28 points) in the Nurse-WIS was 628 (39.4%), and 639 (40.1%) had taken sick leave due to musculoskeletal diseases or psychological impairment during the follow-up period. The odds ratio for sick leave in nurses with a high Nurse-WIS score was 3.42 (95%CI 2.54-4.60). Sensitivity for long-term sick leave (< 42 days) was 64.1%, specificity 63.4%, PPV 17.0% and NPP 93.8%. CONCLUSION The German version of the Nurse-WIS predicts long-term sick leave, but the PPV is rather low. Combining questionnaire data with secondary data from a health insurer was feasible. Therefore further studies employing this combination of data are advisable.

Seidler AL, Rethberg C, Schmitt J, Nienhaus A, Seidler A. Health utilities for chronic low back pain. J Occup Med Toxicol 2017; 12:28. [PMID: 28878813 PMCID: PMC5581438 DOI: 10.1186/s12995-017-0172-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2017] [Accepted: 08/22/2017] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Chronic low back pain (LBP) is a common health problem, with a large potential for primary prevention. Health utilities (HU) reflect which proportion of their expected remaining life time individuals would hypothetically trade to be alleviated of a health condition of interest. A value of 0 means "prefer to die immediately", a value of 1 means "not willing to trade any life time". The aim of this cross-sectional study was to assess HU for LBP patients and for healthy participants and to examine whether HU for LBP are useful indicators to substantiate preventive and therapeutic decision making. METHODS Healthy participants (n = 126) and LBP patients (n = 32) were recruited mainly among the employees of a tertiary care hospital in Germany. Standardized LBP scenarios were presented to all participants and HU values were assessed using the time-trade-off method. RESULTS Median HU for LBP were 0.90 (IQR 0.31) for participants and 0.93 (IQR 0.10) for LBP patients. Measurements were consistent across illness severity ratings with HU and with a visual analogue scale (VAS); in the healthy sample the intraclass correlation coefficient (ICC) was 0.61 (95% CI 0.23-1.00, F(1125) = 190, p < .001), in the patient sample the ICC was 0.66 (95% CI = 0.24-1.00, F(1,31) = 62, p < .001). 8% of participants reported HU of 1. There was no statistically significant relation between HU and age, income, or gender. CONCLUSION On average, participants chose a 7 to 10% shorter life expectancy to avoid LBP, but almost 1 in 10 participants were not willing to trade any life years. The results indicate a certain stability of HU due to the comparability of HU ratings across patients and healthy participants, the measurement consistency when comparing VAS and HU ratings, and the lack of association between demographic variables and HU. This underlines the usefulness of HU for measuring illness severity in comparative health economics evaluations of preventive and therapeutic measures that address chronic LBP or other pain-characterized diseases. Future studies should focus on different LBP intensities and derive stratified HU that reflect the distribution of pain intensity in the population.

Harling M, Schablon A, Peters C, Nienhaus A. Predictive values and other quality criteria of the German version of the Nurse-Work Instability Scale (Nurse-WIS) - follow-up survey findings of a prospective study of a cohort of geriatric care workers. J Occup Med Toxicol 2014; 9:30. [PMID: 25516765 PMCID: PMC4265889 DOI: 10.1186/s12995-014-0030-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2014] [Accepted: 08/20/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Until now there has been a lack of effective screening instruments for health care workers at risk. To counteract the forecast shortage for health care workers, the offer of early interventions to maintain their work ability will become a central concern. The Nurse-Work Instability Scale (Nurse-WIS) seems to be suitable as a screening instrument and therefore a prospective study of a cohort of nursing staff from nursing homes was undertaken to validate the Nurse-Work Instability Scale (Nurse-WIS). METHODS The follow-up data was used to test the sensitivity, specificity and the predictive values of the Nurse-WIS. The participants answered a questionnaire in the baseline investigation (T1) and in a follow-up 12 month after baseline. The hypothesis was that geriatric care workers with an increased risk according to the Nurse-WIS in T1 would be more likely to have taken long-term sick leave or drawn a pension for reduced work capacity in T2. RESULTS 396 persons took part in T1 (21.3% response), 225 in T2 (42.3% loss-to-follow-up). In T1, 28.4% indicated an increased risk according to the Nurse-WIS. In T2, 10.2% had taken long-term sick leave or had drawn a pension for reduced work capacity. The sensitivity is 73.9% (95%-CI 55.7%-92.3%), the specificity is 76.7% (95%-CI 71.2%-82.8%). The ROC AUC indicated a moderate precision for the scale, at 0.74 (95%-CI 0.64-0.84). The PPV of the Nurse-WIS is 26.6%, and the NPV is 96.3%. For those with an increased risk according to the Nurse-WIS, the probability in T2 of long-term sick leave or a pension for reduced work capacity is around eight times higher (OR 8.3, 95%-CI 2.90-23.07). Persons who had indicated a long-term sick leave or made an application for a pension for reduced work capacity in T1 had a 17 times higher risk (OR 17.4, 95%-CI 3.34-90.55). CONCLUSION The German version of the Nurse-WIS appears to be a valid instrument with satisfactory predictive capabilities for recording an impending long-term sick leave. Whether the Nurse-WIS can be used as a screening tool which helps to design risk adjusted prevention programs for the afflicted nurse should be studied.

The role of psychosocial working conditions on burnout and its core component emotional exhaustion - a systematic review. J Occup Med Toxicol 2014; 9:10. [PMID: 24628839 PMCID: PMC4233644 DOI: 10.1186/1745-6673-9-10] [Citation(s) in RCA: 106] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2014] [Accepted: 03/03/2014] [Indexed: 11/29/2022] Open
Abstract
Aims To analyze the association between psychosocial working conditions and burnout and its core component emotional exhaustion, a systematic literature review was undertaken including cohort studies, case–control studies, and randomized controlled trials. Methods The literature search in Medline and PsycInfo was based on a defined search string and strict exclusion and inclusion criteria. Evaluation of the 5,599 initially identified search hits by two independent reviewers and a detailed quality assessment resulted in six methodologically adequate cohort studies considering the relationship between psychosocial working conditions and burnout (one study) as well as the burnout core component emotional exhaustion (five studies). Results The results of our systematic review point to a relationship between psychosocial working conditions and the development of emotional exhaustion/burnout. Particularly high job demands seem to play a role in the development of emotional exhaustion. However, strong intercorrelations between workplace factors, as a matter of principle, make the identification of a single psychosocial workplace factor (being associated with an especially high or low risk of burnout) difficult. Conclusions Multidimensional approaches including reduction of work demands, enhancement of decision latitude and improving the social climate might be promising for preventing burnout and emotional exhaustion. However, methodologically adequate intervention studies are urgently needed to prove the effectiveness of workplace interventions.

J Occup Med Toxicol 2013; 8:33.

Abstract
Background A prospective study of a cohort of nursing staff from nursing homes was undertaken to validate the Nurse-Work Instability Scale (Nurse-WIS). Baseline investigation data was used to test reliability, construct validity and criterion validity. Method A survey of nursing staff from nursing homes was conducted using a questionnaire containing the Nurse-WIS along with other survey instruments (including SF-12, WAI, SPE). The self-reported number of days’ sick leave taken and if a pension for reduced work capacity was drawn were recorded. The reliability of the scale was checked by item difficulty (P), item discrimination (rjt) and by internal consistency according to Cronbach’s coefficient. The hypotheses for checking construct validity were tested on the basis of correlations. Pearson’s chi-square was used to test concurrent criterion validity; discriminant validity was tested by means of binary logistic regression. Results 396 persons answered the questionnaire (21.3% response rate). More than 80% were female and mostly work full-time in a rotating shift pattern. Following the test for item discrimination, two items were removed from the Nurse-WIS test. According to Cronbach’s (0.927) the scale provides a high degree of measuring accuracy. All hypotheses and assumptions used to test validity were confirmed: As the Nurse-WIS risk increases, health-related quality of life, work ability and job satisfaction decline. Depressive symptoms and a poor subjective prognosis of earning capacity are also more frequent. Musculoskeletal disorders and impairments of psychological well-being are more frequent. Age also influences the Nurse-WIS result. While 12.0% of those below the age of 35 had an increased risk, the figure for those aged over 55 was 50%. Conclusion This study is the first validation study of the Nurse-WIS to date. The Nurse-WIS shows good reliability, good validity and a good level of measuring accuracy. It appears to be suitable for recording prevention and rehabilitation needs among health care workers. If, in the follow-up, the Nurse-WIS likewise proves to be a reliable screening instrument with good predictive validity, it could ensure that suitable action is taken at an early stage, thereby helping to counteract early retirement and the anticipated shortage of health care workers.

Posadzki P, Ernst E. Yoga for low back pain: a systematic review of randomized clinical trials. Clin Rheumatol 2011; 30:1257-62. [PMID: 21590293 DOI: 10.1007/s10067-011-1764-8] [Citation(s) in RCA: 65] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2011] [Accepted: 04/21/2011] [Indexed: 12/15/2022]
Abstract
It has been suggested that yoga has a positive effect on low back pain and function. The objective of this systematic review was to assess the effectiveness of yoga as a treatment option for low back pain. Seven databases were searched from their inception to March 2011. Randomized clinical trials were considered if they investigated yoga in patients with low back pain and if they assessed pain as an outcome measure. The selection of studies, data extraction and validation were performed independently by two reviewers. Seven randomized controlled clinical trials (RCTs) met the inclusion criteria. Their methodological quality ranged between 2 and 4 on the Jadad scale. Five RCTs suggested that yoga leads to a significantly greater reduction in low back pain than usual care, education or conventional therapeutic exercises. Two RCTs showed no between-group differences. It is concluded that yoga has the potential to alleviate low back pain. However, any definitive claims should be treated with caution.

Abstract
The practice of hathayoga is based on the following assumptions: complexity and multidimensionality of various positive influences on an individual's wholeness through the mind, body and their conscious control. On the other hand, the practice of the qigong of 18 Luohan Hands is based on slow movements designed to mobilise qi within the body. This article presents a conceptual integration of yoga and qigong when considering the congruence of beneficial effects for various systems of the body and prevention of low back pain (LBP). The author emphasizes the usefulness of qigong and yoga practice in clinical units and explains how the essence of these practices relates to each other. The justification of this fusion as well as differences between these two modalities are also described and explained. Within the scope of this article the existence of several similarities between these two practices has been suggested for both practitioners and researchers. They can obtain valuable and additional arguments through cross-fertilization of ideas across presented studies united by shared, underlying biomechanical concepts and physiological effects. Such conceptual enrichment may be a useful source of inspiration for qigong and yoga practitioners who tend to prevent LBP and therapists (physiotherapists, occupational therapists, rehabilitants, nurses, bodywork and movement therapists or massage therapists) intended to manage their patients' back pains and overall health on a daily basis.

Abstract
OBJECTIVE The aim of this paper is to systematically review all controlled clinical trials of Pilates to treat low back pain. DATA SOURCES A systematic review of nine databases (Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, AMED, PsycINFO, Pedro, Rehadat, Rehab Trials) was conducted and the reference lists of all the papers were checked for further relevant publications until May 2010. STUDY SELECTION A first selection was performed by means of title and abstract. A second selection was made by means of predefined inclusion criteria: randomized controlled clinical trials testing Pilates in patients of any age or sex with low back pain. DATA EXTRACTION Data relating to changes in body function, quality of life and pain from the included studies were independently extracted by the reviewers on a standardized form. Study quality was assessed using the Oxford scale. DATA SYNTHESIS Four eligible randomized controlled clinical trials (n = 4) involving Pilates for the management of low back pain were included. The methodological quality of the RCTs was relatively low, varying from 1-4 on the Oxford scale. All studies were heterogeneous in terms of population of patients, control groups, inclusion and exclusion criteria, and outcome measures making a meta-analysis not feasible. Although there is some evidence supporting the effectiveness of Pilates in the management of low back pain, no definite conclusions can be drawn except that further research is needed with larger samples and using clearer definitions of the standard care and comparable outcome measures. CONCLUSIONS There is a wide diversity in research investigating the clinical and cost-effectiveness of Pilates in patients with low back pain.

Abstract
Background Back pain is one of the most frequent complaints in the nursing profession. Thus, the 12-month prevalence of pain in the lumbar spine in nursing staff is as high as 76%. Only a few representative studies have assessed the prevalence rates of back pain and its risk factors among nursing staff in nursing homes in comparison to staff in home-based care facilities. The present study accordingly investigates the prevalence in the lumbar and cervical spine and determines the physical workload to lifting and caring in geriatric care. Methods 1390 health care workers in nursing homes and home care participated in this cross sectional survey. The nursing staff members were examined by occupational physicians according to the principals of the multistep diagnosis of musculoskeletal disorders. Occupational exposure to daily care activities with patient transfers was measured by a standardised questionnaire. The lumbar load was calculated with the Mainz-Dortmund dose model. Information on ergonomic conditions were recorded from the management of the nursing homes. Comparisons of all outcome variables were made between both care settings. Results Complete documentation, including the findings from the occupational physicians and the questionnaire, was available for 41%. Staff in nursing homes had more often positive orthopaedic findings than staff in home care. At the same time the values calculated for lumbar load were found to be significant higher in staff in nursing homes than in home-based care: 45% vs. 6% were above the reference value. Nursing homes were well equipped with technical lifting aids, though their provision with assistive advices is unsatisfactory. Situation in home care seems worse, especially as the staff often has to get by without assistance. Conclusions Future interventions should focus on counteracting work-related lumbar load among staff in nursing homes. Equipment and training in handling of assistive devices should be improved especially for staff working in home care.
