Organizational climate and occupational health outcomes in hospital nurses.

OBJECTIVE: The objective of this study was to determine relationships between organizational climate (OC) factors and occupational health outcomes (lost workdays, musculoskeletal injury, blood and body fluid exposures, injuries, and burnout) among hospital-based nurses. METHODS: Measures were obtained through a self-administered, anonymous survey distributed in 13 New York City hospitals. Multivariate models appropriate for clustered data were developed. These analyses controlled for nurse and employment characteristics. Independent effects of OC factors were examined. RESULTS: Surveys from 2047 predominantly registered nurses were obtained (response rate 50%). More than 75% reported lost workdays due to illness in the previous 4-month period and over one third reported experiencing some type of injury. OC factors were independently associated with injuries and measures of burnout (P < or = 0.05). CONCLUSIONS: OC is significantly associated with the health and well-being of hospital nurses.

Reducing premature infants' length of stay and improving parents' mental health outcomes with the Creating Opportunities for Parent Empowerment (COPE) neonatal intensive care unit program: a randomized, controlled trial.

OBJECTIVE: Although low birth weight premature infants and parents are at high risk for adverse health outcomes, there is a paucity of studies that test early NICU interventions with parents to prevent the development of negative parent-infant interaction trajectories and to reduce hospital length of stay. Our objective was to evaluate the efficacy of an educational-behavioral intervention program (ie, Creating Opportunities for Parent Empowerment) that was designed to enhance parent-infant interactions and parent mental health outcomes for the ultimate purpose of improving child developmental and behavior outcomes. DESIGN, SETTING, AND PARTICIPANTS: A randomized, controlled trial was conducted with 260 families with preterm infants from 2001 to 2004 in 2 NICUs in the northeast United States. Parents completed self-administered instruments during hospitalization, within 7 days after infant discharge, and at 2 months' corrected age. Blinded observers rated parent-infant interactions in the NICU. INTERVENTION: All participants received 4 intervention sessions of audiotaped and written materials. Parents in the Creating Opportunities for Parent Empowerment program received information and behavioral activities about the appearance and behavioral characteristics of preterm infants and how best to parent them. The comparison intervention contained information regarding hospital services and policies. MAIN OUTCOME MEASURES: Parental stress, depression, anxiety, and beliefs; parent-infant interaction during the NICU stay; NICU length of stay; and total hospitalization were measured. RESULTS: Mothers in the Creating Opportunities for Parent Empowerment program reported significantly less stress in the NICU and less depression and anxiety at 2 months' corrected infant age than did comparison mothers. Blinded observers rated mothers and fathers in the Creating Opportunities for Parent Empowerment program as more positive in interactions with their infants. Mothers and fathers also reported stronger beliefs about their parental role and what behaviors and characteristics to expect of their infants during hospitalization. Infants in the Creating Opportunities for Parent Empowerment program had a 3.8-day shorter NICU length of stay (mean: 31.86 vs 35.63 days) and 3.9-day shorter total hospital length of stay (mean: 35.29 vs 39.19 days) than did comparison infants. CONCLUSIONS: A reproducible educational-behavioral intervention program for parents that commences early in the NICU can improve parent mental health outcomes, enhance parent-infant interaction, and reduce hospital length of stay.

Nurse turnover: a literature review.

Ongoing instability in the nursing workforce is raising questions globally about the issue of nurse turnover. A comprehensive literature review was undertaken to examine the current state of knowledge about the scope of the nurse turnover problem, definitions of turnover, factors considered to be determinants of nurse turnover, turnover costs and the impact of turnover on patient, and nurse and system outcomes. Much of the research to date has focused on turnover determinants, and recent studies have provided cost estimations at the organizational level. Further research is needed to examine the impact of turnover on health system cost, and how nurse turnover influences patient and nurse outcomes.

Organizational climate and intensive care unit nurses' intention to leave.

OBJECTIVE: The purposes of this study were to a) estimate the incidence of intensive care units nurses' intention to leave due to working conditions; and b) identify factors predicting this phenomenon. DESIGN: Cross-sectional design. SETTING: Hospitals and critical care units. SUBJECTS: Registered nurses (RNs) employed in adult intensive care units. INTERVENTIONS: Organizational climate, nurse demographics, intention to leave, and reason for intending to leave were collected using a self-report survey. MEASUREMENTS AND MAIN RESULTS: Nurses were categorized into two groups: a) those intending to leave due to working conditions; and b) others (e.g., those not leaving or retirees). The measure of organizational climate had seven subscales: professional practice, staffing/resource adequacy, nurse management, nursing process, nurse/physician collaboration, nurse competence, and positive scheduling climate. Setting characteristics came from American Hospital Association data and a survey of chief nursing officers. RESULTS: A total of 2,323 RNs from 66 hospitals and 110 critical care units were surveyed across the nation. On average, the RN was 39.5 yrs old (SD = 9.40), had 15.6 yrs (SD = 9.20) experience in health care, and had worked in his or her current position for 8.0 yrs (SD = 7.50). Seventeen percent (n = 391) of the respondents indicated intending to leave their position in the coming year. Of those, 52% (n = 202) reported that the reason was due to working conditions. Organizational climate factors that had an independent effect on intensive care unit nurse intention to leave due to working conditions were professional practice, nurse competence, and tenure (p < .05). CONCLUSIONS: Improving professional practice in the work environment and clinical competence of the nurses as well as supporting new hires may reduce turnover and help ensure a stable and qualified workforce.

When is critical care medicine cost-effective? A systematic review of the cost-effectiveness literature.

BACKGROUND: Receiving care in an intensive care unit can greatly influence patients' survival and quality of life. Such treatments can, however, be extremely resource intensive. Therefore, it is increasingly important to understand the costs and consequences associated with interventions aimed at reducing mortality and morbidity of critically ill patients. Cost-effectiveness analyses (CEAs) have become increasingly common to aid decisions about the allocation of scarce healthcare resources. OBJECTIVES: To identify published original CEAs presenting cost/quality-adjusted life year or cost/life-year ratios for treatments used in intensive care units, to summarize the results in an accessible format, and to identify areas in critical care medicine that merit further economic evaluation. METHODS: We conducted a systematic search of the English-language literature for original CEAs of critical care interventions published from 1993 through 2003. We collected data on the target population, therapy or program, study results, analytic methods employed, and the cost-effectiveness ratios presented. RESULTS: We identified 19 CEAs published through 2003 with 48 cost-effectiveness ratios pertaining to treatment of severe sepsis, acute respiratory failure, and general critical care interventions. These ratios ranged from cost saving to 958,423 US dollars/quality-adjusted life year and from 1,150 to 575,054 US dollars/life year gained. Many studies reported favorable cost-effectiveness profiles (i.e., below 50,000 US dollars/life year or quality-adjusted life year). CONCLUSIONS: Specific interventions such as activated protein C for patients with severe sepsis have been shown to provide good value for money. However, overall there is a paucity of CEA literature on the management of the critically ill, and further high-quality CEA is needed. In particular, research should focus on costly interventions such as 24-hr intensivist availability, early goal-directed therapy, and renal replacement therapy. Recent guidelines for the conduct of CEAs in critical care may increase the number and improve the quality of future CEAs.

Comparison of nurse, system and quality patient care outcomes in 8-hour and 12-hour shifts.

BACKGROUND: Many nurses desire 12-hour shifts. However, there are concerns about implementation. OBJECTIVE: We sought to compare the effects of 8- and 12-hour shifts on nurse, system, and quality patient care outcomes. METHODS: We used a cross-sectional design with data collected from multiple sources in 2003-2004, including a nurse survey and administrative and patient records. We studied hospital nurses and patients in general adult wards, with outcomes including burnout, job satisfaction, scheduling satisfaction, preferences, intention to stay, and employee safety. System outcomes included recruitment and turnover, staffing, absenteeism, and related costs. A variety of quality patient care outcomes were measured from the 3 different types of data. RESULTS: Thirteen New York City hospitals participated; 805 surveys were examined from 99 nursing units (response rate 42%). Compared with nurses working 8-hour shifts, those working 12-hour shifts were on average more satisfied with their jobs, experienced less emotional exhaustion, 10 times more likely to be satisfied with schedules, 2 times as likely to perceive 12-hour schedules as important, and 58% less likely to report missing shifts; units with 12-hour shifts had lower vacancy rates and weeks to fill the position (all P values < or =0.05). There were no differences in patient outcomes. CONCLUSIONS: Nurses working 12-hour shifts were more satisfied. There were no differences in quality outcomes. Flexibility and choice in shift length are important elements in a positive nurse work environment. This study represents an innovative attempt by a labor-management bargaining group to make an evidence-based decision. We encourage others to conduct similar studies.

The impact of nurse turnover on patient, nurse, and system outcomes: a pilot study and focus for a multicenter international study.

Research about the economic impact of nurse turnover has been compromised by a lack of consistent definitions and measurement. This article describes a study that was designed to refine a methodology to examine the costs associated with nurse turnover. Nursing unit managers responded to a survey that contained items relating to budgeted full-time equivalents, new hires, and turnover, as well as direct and indirect costs. The highest mean direct cost was incurred through temporary replacements, whereas the highest indirect cost was decreased initial productivity of the new hire. The study allowed the identification of the availability of data and where further refinement of data definition of variables is needed. The results provided significant evidence to justify increased emphasis on nurse retention strategies and the creation of healthy work environments for nurses.

Knowledge content of advance practice nurse and physician experts: A cognitive evaluation of clinical practice guideline comprehension.

Clinical practice guidelines (CPGs) are intended to provide evidence based knowledge for decision making for patient care. However, these guidelines have been poorly adopted by healthcare providers. One reason for this may be the static paper-based formats, isolated from the point of care. Biomedical informatics has provided a solution to this limitation through Computer Interpretable Guidelines (CIGs). An essential component of this process is CPG translation to a computer interpretable model. From the guideline modeling literature, the translators of CPGs typically are physicians. It is not known if other healthcare providers (i.e., Advance Practice Nurses [APNs]) comprehend CPGs similarly. This descriptive study utilized novice and expert APN and physician participants (varied by level of expertise) in a CPG comprehension task. Demographic data, verbal protocols, and recall model drawings were obtained and analyzed by description, protocol analysis, discourse analysis, and content analysis. The findings of this study indicate similar comprehension by the expert APNs and physicians suggesting that either type of expert may be utilized for modeling CPGs.

Systematic review of economic analyses of health care-associated infections.

BACKGROUND: Economic evidence is needed to assess the burden of health care-associated infections (HAIs) and cost-effectiveness of interventions aimed at reducing related morbidity and mortality. The objective of this study was conducted to assess the quality of economic evaluations related to HAI and synthesize the evidence. METHODS: A systematic review of research published between January 2001 and June 2004 was conducted. Quality of the publication was estimated using a Likert-type scale. All cost estimates were standardized into a common currency. Descriptive statistics and a logistic regression were conducted to identify predictors of high quality. RESULTS: 70 studies were audited. There was wide variation in these cost estimates. Publications estimating the cost attributable to an infection were almost 7 times more likely judged to be of higher quality than studies of the cost of interventions (P < .05). Papers in which the authors stated the perspective (hospital or societal) were twice as likely to be judged as being of high quality (P < .05). CONCLUSION: There are more publications and growing interest in estimating the costs of HAI. However, the methods employed vary. We recommend (1) the use of guidelines for authors and editors on conducting an economic analysis, (2) development of more sophisticated mathematical models, and (3) training of infection control professionals in economic methods.

A synthesis of cost-utility analysis literature in infectious disease.

The purpose of this review is to understand infectious disease-related cost-utility analyses by describing published analyses, examining growth and quality trends over time, examining factors related to quality, and summarising standardised results. 122 cost-utility analyses and 352 cost-utility ratios were identified. Pharmaceutical interventions were most common (47.5%); three author groups accounted for 42.8% of pharmaceutical ratios. High-volume journals (three or more published cost-utility analyses) published higher quality analyses than low-volume journals (p<0.001). Use of probabilistic sensitivity analysis and discounting at 3% were more frequently found in the years after the US Public Health Service Panel on Cost-Effectiveness in Health and Medicine recommendations (p<0.01). Median ratios varied from US13,500 dollars/quality-adjusted life year (QALY) for immunisations to US810,000 dollars/QALY for blood safety. Publication of infectious disease cost-utility analyses is increasing. The results of cost-utility analyses have important implications for the development of clinical guidelines and resource allocation decisions. More trained investigators and better peer-review processes are needed.

Measurement of organizational culture and climate in healthcare.

Although there is increasing interest in the relationship between organizational constructs and health services outcomes, information on the reliability and validity of the instruments measuring these constructs is sparse. Twelve instruments were identified that may have applicability in measuring organizational constructs in the healthcare setting. The authors describe and characterize these instruments and discuss the implications for nurse administrators.

How often do sensitivity analyses for economic parameters change cost-utility analysis conclusions?

BACKGROUND: There is limited evidence about the extent to which sensitivity analysis has been used in the cost-effectiveness literature. Sensitivity analyses for health-related QOL (HR-QOL), cost and discount rate economic parameters are of particular interest because they measure the effects of methodological and estimation uncertainties. AIM: To investigate the use of sensitivity analyses in the pharmaceutical cost-utility literature in order to test whether a change in economic parameters could result in a different conclusion regarding the cost effectiveness of the intervention analysed. METHODS: Cost-utility analyses of pharmaceuticals identified in a prior comprehensive audit (70 articles) were reviewed and further audited. For each base case for which sensitivity analyses were reported (n = 122), up to two sensitivity analyses for HR-QOL (n = 133), cost (n = 99), and discount rate (n = 128) were examined. Article mentions of thresholds for acceptable cost-utility ratios were recorded (total 36). Cost-utility ratios were denominated in US dollars for the year reported in each of the original articles in order to determine whether a different conclusion would have been indicated at the time the article was published. Quality ratings from the original audit for articles where sensitivity analysis results crossed the cost-utility ratio threshold above the base-case result were compared with those that did not. RESULTS: The most frequently mentioned cost-utility thresholds were $US20,000/QALY, $US50,000/QALY, and $US100,000/QALY. The proportions of sensitivity analyses reporting quantitative results that crossed the threshold above the base-case results (or where the sensitivity analysis result was dominated) were 31% for HR-QOL sensitivity analyses, 20% for cost-sensitivity analyses, and 15% for discount-rate sensitivity analyses. Almost half of the discount-rate sensitivity analyses did not report quantitative results. Articles that reported sensitivity analyses where results crossed the cost-utility threshold above the base-case results (n = 25) were of somewhat higher quality, and were more likely to justify their sensitivity analysis parameters, than those that did not (n = 45), but the overall quality rating was only moderate. CONCLUSIONS: Sensitivity analyses for economic parameters are widely reported and often identify whether choosing different assumptions leads to a different conclusion regarding cost effectiveness. Changes in HR-QOL and cost parameters should be used to test alternative guideline recommendations when there is uncertainty regarding these parameters. Changes in discount rates less frequently produce results that would change the conclusion about cost effectiveness. Improving the overall quality of published studies and describing the justifications for parameter ranges would allow more meaningful conclusions to be drawn from sensitivity analyses.
