An epidemiological study of the magnitude and consequences of work related violence: the Minnesota Nurses' Study

Aims: To identify the magnitude of and potential risk factors for violence within a major occupational population. Methods: Comprehensive surveys were sent to 6300 Minnesota licensed registered (RNs) and practical (LPNs) nurses to collect data on physical and non-physical violence for the prior 12 months. Re-weighting enabled adjustment for potential biases associated with non-response, accounting for unknown eligibility. Results: From the 78% responding, combined with non-response rate information, respective adjusted rates per 100 persons per year (95% CI) for physical and non-physical violence were 13.2 (12.2 to 14.3) and 38.8 (37.4 to 40.4); assault rates were increased, respectively, for LPNs versus RNs (16.4 and 12.0) and males versus females (19.4 and 12.9). Perpetrators of physical and non-physical events were patients/clients (97% and 67%, respectively). Consequences appeared greater for non-physical than physical violence. Multivariate modelling identified increased rates for both physical and non-physical violence for working: in a nursing home/long term care facility; in intensive care, psychiatric/behavioural or emergency departments; and with geriatric patients. Conclusions: Results show that non-fatal physical assault and non-physical forms of violence, and relevant consequences, are frequent among both RNs and LPNs; such violence is mostly perpetrated by patients or clients; and certain environmental factors appear to affect the risk of violence. This serves as the basis for further analytical studies that can enable the development of appropriate prevention and control efforts.

Postpartum depression screening at well-child visits: validity of a 2-question screen and the PHQ-9.

PURPOSE Postpartum depression affects up to 22% of women who have recently given birth. Most mothers are not screened for this condition, and an ideal screening tool has not been identified. This study investigated (1) the validity of a 2-question screen and the 9-item Patient Health Questionnaire (PHQ-9) for identifying postpartum depression and (2) the feasibility of screening for postpartum depression during well-child visits. METHODS Study participants were English-literate mothers registering their 0- to 1-month-old infants for well-child visits at 7 family medicine or pediatric clinics. They were asked to complete questionnaires during well-child visits at 0 to 1, 2, 4, 6, and 9 months postpartum. Each questionnaire included 2 depression screens: the 2-question screen and the PHQ-9. The mothers also completed the depression component of the Structured Clinical Interview for DSM-IV (SCID) initially, and again at a subsequent interval if either screening result was positive for depression. RESULTS The response rate was 33%. Of the 506 women who participated, 45 (8.9%) had major depression (ie, they had a positive result on the SCID). The screen sensitivities/specificities over the course of the study were 100%/44% with the 2-question screen, 82%/84% with the PHQ-9 using simple scoring, and 67%/92% with the PHQ-9 using complex scoring. In addition, the corresponding values for the first 2 items of the PHQ-9 (ie, the 2-item Patient Health Questionnaire or PHQ-2) were 84%/79%. Some 38% of women completed their 2- to 6-month questionnaires during well-child visits; the rest completed them by mail (29%) or telephone (33%). CONCLUSIONS The 2-question screen was highly sensitive and the PHQ-9 was highly specific for identifying postpartum depression. These results suggest the value of a 2-stage procedure for screening for postpartum depression, whereby a 2-question screen that is positive for depression is followed by a PHQ-9. These screens can be easily administered in primary care clinics; feasibility of screening during well-child visits was moderate but may be better in clinics using a mass-screening approach.

Women's work roles and their impact on health, well-being, and career: comparisons between the United States, Sweden, and The Netherlands.

ABSTRACT As women have become more assimilated into the workforce over recent decades, they have realized considerable changes in their work roles which may contribute to health problems and other negative outcomes such as marital strain and diminished job status. The purpose of this review was threefold: (1) to synthesize data on the distribution of womens work efforts in the areas of paid employment, household chores, and childcare; (2) to outline research which addresses the impact of womens workload on their well-being and careers; and (3) to make international and gender comparisons regarding womens work responsibilities. Our findings showed that women from each of the three countries examined–the United States, Sweden, and The Netherlands–contribute more effort to household chores and childcare and less to the workplace than men do. As a result, their total workloads appear to be somewhat greater and more diffusely distributed than those of men. Heavy workloads may adversely affect womens health, especially in the presence of certain role characteristics (e.g., having a clerical, managerial, professional, or executive position, or caring for young children). Heavy work responsibilities may also undermine marital happiness, particularly if there is perceived inequity in the way partners share household work. Finally, womens total work responsibilities often impact their careers due to compensatory reductions in work commitment and job status. These observations point to the need for further research on womens workload and work roles, on the relationship of work to well-being, and on methods of preventing or alleviating adverse effects on overburdened workers.

Association Between Lymph Node Evaluation for Colon Cancer and Node Positivity Over the Past 20 Years

CONTEXT Among patients surgically treated for colon cancer, better survival has been demonstrated in those with more lymph nodes evaluated. The presumed mechanism behind this association suggests that a more extensive lymph node evaluation reduces the risk of understaging, leading to improved survival. OBJECTIVE To further evaluate the mechanism behind lymph node evaluation and survival by examining the association between more extensive lymph node evaluation, identification of lymph node-positive cancers, and hazard of death. DESIGN Observational cohort study. SETTING Surveillance, Epidemiology, and End Results (SEER) program data from 1988 through 2008. PATIENTS 86,394 patients surgically treated for colon cancer. MAIN OUTCOME MEASURE We examined the relationship between lymph node evaluation and node positivity using Cochran-Armitage tests and multivariate logistic regression. The association between lymph node evaluation and hazard of death was evaluated using Cox proportional hazards modeling. RESULTS The number of lymph nodes evaluated increased from 1988 to 2008 but did not result in a significant overall increase in lymph node positivity. During 1988-1990, 34.6% of patients (3875/11,200) had 12 or more lymph nodes evaluated, increasing to 73.6% (9798/13,310) during 2006-2008 (P < .001); however, the proportion of node-positive cancers did not change with time (40% in 1988-1990, 42% in 2006-2008, P = .53). Although patients with high levels of lymph node evaluation were only slightly more likely to be node positive (adjusted odds ratio for 30-39 nodes vs 1-8 nodes, 1.11; 95% CI, 1.02-1.20), these patients experienced significantly lower hazard of death compared with those with fewer nodes evaluated (adjusted hazard ratio for 30-39 nodes vs 1-8 nodes, 0.66; 95% CI, 0.62-0.71; unadjusted 5-year mortality, 35.3%). CONCLUSION The number of lymph nodes evaluated for colon cancer has markedly increased in the past 2 decades but was not associated with an overall shift toward higher-staged cancers, questioning the upstaging mechanism as the primary basis for improved survival in patients with more lymph nodes evaluated.

Risk factors for work-related assaults on nurses

Background: Work-related homicides have been the subject of considerable study, but little is known about nonfatal violence and relevant risk factors. Methods: We surveyed 6300 Minnesota nurses who were selected randomly from the 1998 licensing database and determined their employment and occupational violence experience. In a nested case–control study, we examined environmental exposures and physical assault. Cases of assault in the previous 12 months and controls randomly selected from assault-free months were surveyed about prior-month exposures. Results: After adjustment by multiple logistic regression, incidence of physical assault was 13.2 per 100 persons per year (95% confidence interval = 12.2–14.3). Among 310 cases and 946 control subjects, odds ratios for assault were increased: in nursing homes or long-term care facilities (2.6; 1.9–3.6), emergency departments (4.2; 1.3–12.8), and psychiatric departments (2.0; 1.1–3.7); in environments not “bright as daylight” (2.2; 1.6–2.8); and for each additional hour of shift duration (1.05; 0.99–1.11). Risks were decreased when carrying cellular telephones or personal alarms (0.3; 0.2–0.7). Conclusions: These results may guide in-depth investigation of ways protective and risk factors can control violence against nurses.

Postpartum Health of Employed Mothers 5 Weeks After Childbirth

PURPOSE Most new mothers return to work soon after childbirth. A need exists to reexamine the definition of postpartum health and evaluate employed women’s recovery from childbirth in association with such factors as delivery type and breastfeeding. METHODS Using a prospective cohort design, we recruited Minnesota women into the study while they were hospitalized for childbirth in 2001. Telephone interviews were conducted 5 weeks postpartum. Eligible women were 18 years or older, employed, and spoke English. Multivariate models using 2-stage least squares were used to estimate factors associated with physical and mental health and postpartum symptoms. RESULTS A total of 817 women were enrolled (71% response) in the study; 716 women completed interviews at 5 weeks postpartum. On average, women reported 6 postpartum symptoms, most frequently fatigue (64%), breast discomfort (60%), and decreased desire for sex (52%). Findings showed that cesarean (vs vaginal) deliveries were associated with significantly worse physical function, role limitations, and vitality. Multivariate findings showed that the effect of delivery type on physical health was moderately large (β = −5.96; P = <.01), and breastfeeding was associated with an increased frequency of postpartum symptoms (β = 4.63; P = .01). CONCLUSIONS These mothers experienced several childbirth-related symptoms at 5 weeks postpartum, indicating a need for ongoing rest and recovery. Health concerns were greater for women who were breastfeeding and for those whose babies were delivered by cesarean section, suggesting a need for greater support for these women and a reassessment by the medical community of the progressively growing practice of cesarean deliveries.

Risk factors for work related violence in a health care organization

Objective: Identify the exposure effects of job family, patient contact, and supervisor support on physical and non-physical work related violence. Design: Cross sectional study of employees in a Midwest health care organization, utilizing a specially designed mailed questionnaire and employer secondary data. Subjects: Respondents included 1751 current and former employees (42% response rate). Results: Physical and non-physical violence was experienced by 127 (7.2%) and 536 (30.6%) of the respondents, respectively. Multivariate analyses of physical violence identified increased odds for patient care assistants (odds ratio (OR) 2.5, 95% confidence interval (CI) 1. 1 to 6.1) and decreased odds for clerical workers (OR 0.1, 95% CI 0.03 to 0.5). Adjusted for job family, increased odds of physical violence were identified for moderate (OR 5.9, 95% CI 2.1 to 16.0) and high (OR 7.8, 95% CI 2.9 to 20.8) patient contact. Similar trends were identified for non-physical violence (OR 1.4, 95% CI 1.1 to 2.0 and OR 1.7, 95% CI 1.3 to 2.3). Increased supervisor support decreased the odds of both physical (OR 0.7, 95% CI 0.6 to 0.95) and non-physical violence (OR 0.5, 95% CI 0.4 to 0.6), adjusting for job family and demographic characteristics. Conclusions: Increased odds of physical violence were identified for the job family of nurses, even when adjusted for patient contact. Increased patient contact resulted in increased physical and non-physical violence, independent of job family, while supervisor support resulted in decreased odds of physical and non-physical violence.

Mothers’ Health and Work-Related Factors at 11 Weeks Postpartum

PURPOSE Many new mothers return to work soon after childbirth. This study examines personal and work-related factors associated with the postpartum health of employed women 11 weeks after childbirth. METHODS Using a prospective cohort design, we recruited 817 Minnesota mothers into the study while they were hospitalized for childbirth in 2001. Telephone interviews were conducted at 5 and 11 weeks postpartum. Eligible women were 18 years or older, employed, and spoke English and gave birth to a singleton infant. Multivariate models using instrumental variables (2-stage least squares) were used to estimate personal and employment characteristics associated with women’s physical and mental health and postpartum symptoms. RESULTS At 11 weeks postpartum, 661 participants (81% of enrollees) completed a full interview, and 50% of participants had returned to work. On average, women reported 4.1 (SD 3.2) childbirth-related symptoms, most frequently fatigue (43%). Factors significantly associated with better health outcomes included better preconception health, the absence of prenatal mood problems, more control over work and home activities, more social support at work and home, and less job stress. CONCLUSIONS The findings suggest postpartum women need to be evaluated regarding their fatigue levels and mental and physical symptoms. Women whose fatigue or postpartum symptoms limit daily role function may find it helpful to have health care clinicians counsel them on strategies to decrease job stress, increase social support at work and home, and certify their use of intermittent family and medical leave to help them manage their symptoms.

Needlestick injuries among health care workers. A literature review.

Needlestick injuries among health care workers are a recognized health hazard, with 400,000 needlesticks occurring annually among the 4 million health care workers in the United States. Existing needlestick injury literature primarily focuses on hospital sites and may not be generalizable to other health care settings such as nursing homes, home health care sites, clinics, and emergency response units. Nurses were at high risk of needlestick injury from syringes and i.v. equipment relative to the other health care workers. Recapping, prohibited by the OSHA Bloodborne Pathogens Standard, continues to be an identified cause of injury. The literature supports comprehensive injury prevention and control strategies in conjunction with the use of safer needle devices. Health care organizations should assess their worksites to identify hazards and select products and strategies to correct the problem. Future research should clarify accurate needlestick injury rates (e.g., establish consistent denominators), address non-hospital setting risks, validate self reported data, and evaluate comprehensive interventions that employ engineering strategies to minimize the risk.

Work-related assault injuries among nurses.

Work-related violence is a major public health problem; however, there is a serious deficiency in the knowledge of risk factors for this problem. The purpose of this case-control study was to identify risk factors for work-related assault injuries among nurses. We used unconditional logistic regression to model the dependence of work-related assault injuries on each exposure of interest and the respective confounders. We found a decreased rate for the presence of security personnel (RR = 0.40; 95% CI = 0.19-0.82). We found increased rates for the following factors: the perception that administrators considered assault to be part of the job (RR = 8.14; 95% CI = 3.76-17.60); having received assault prevention training in the current workplace (RR = 4.64; 95% CI = 2.33-9.23); a high (>5) vs. low (<2) patient/personnel ratio (RR = 2.54; 95% CI = 1.13-5.70); working predominantly with patients with mental illness (RR = 3.5; 95% CI = 1.41-8.85); and working with patients who had more than 1- to 4-week and more than 4-week lengths of stay in the institution vs. <1 day (RR = 8.85; 95% CI = 1.58-49.52 and 4.25; 95% CI = 1.17-15.39, respectively).
