Randomized controlled trial of hands-and-knees positioning for occipitoposterior position in labor

BACKGROUND

Hands-and-knees positioning during labor has been recommended on the theory that gravity and buoyancy may promote fetal head rotation to the anterior position and reduce persistent back pain. A Cochrane review found insufficient evidence to support the effectiveness of this intervention during labor. The purpose of this study was to evaluate the effect of maternal hands-and-knees positioning on fetal head rotation from occipitoposterior to occipitoanterior position, persistent back pain, and other perinatal outcomes.

METHODS

Thirteen labor units in university-affiliated hospitals participated in this multicenter randomized, controlled trial. Study participants were 147 women laboring with a fetus at >or=37 weeks' gestation and confirmed by ultrasound to be in occipitoposterior position. Seventy women were randomized to the intervention group (hands-and-knees positioning for at least 30 minutes over a 1-hour period during labor) and 77 to the control group (no hands-and-knees positioning). The primary outcome was occipitoanterior position determined by ultrasound following the 1-hour study period and the secondary outcome was persistent back pain. Other outcomes included operative delivery, fetal head position at delivery, perineal trauma, Apgar scores, length of labor, and women's views with respect to positioning.

RESULTS

Women randomized to the intervention group had significant reductions in persistent back pain. Eleven women (16%) allocated to use hands-and-knees positioning had fetal heads in occipitoanterior position following the 1-hour study period compared with 5 (7%) in the control group (relative risk 2.4; 95% CI 0.88-6.62; number needed to treat 11). Trends toward benefit for the intervention group were seen for several other outcomes, including operative delivery, fetal head position at delivery, 1-minute Apgar scores, and time to delivery.

CONCLUSIONS

Maternal hands-and-knees positioning during labor with a fetus in occipitoposterior position reduces persistent back pain and is acceptable to laboring women. Given this evidence, hands-and-knees positioning should be offered to women laboring with a fetus in occipitoposterior position in the first stage of labor to reduce persistent back pain. Although this study demonstrates trends toward improved birth outcomes, further trials are needed to determine if hands-and-knees positioning promotes fetal head rotation to occipitoanterior and reduces operative delivery.

Consistent Management of Repeated Procedural Pain With Sucrose in Preterm Neonates: Is It Effective and Safe for Repeated Use Over Time?

OBJECTIVE

Preterm neonates undergo numerous painful procedures in the neonatal intensive care unit (NICU). Sucrose, with and without pacifiers, is effective and safe for relieving pain from single painful events. However, repeated use of sucrose for multiple painful procedures has not been adequately evaluated. The study objectives were to: 1) determine the efficacy and safety of consistent management of repeated procedural pain with sucrose; and 2) explore the impact of consistent pain management on clinical outcomes and neurobiological risk status.

METHODS

Sixty-six preterm infants were randomized to receive standard care (positioning and swaddling; n = 21), sterile water plus pacifier (n = 23), or 24% sucrose plus pacifier (n = 22) prior to all painful procedures in the NICU during the first 28 days of life. Also, at a routine heel lance at 7, 14, 21, and 28 days of life, data were collected to determine efficacy and immediate and long-term adverse events. Data on clinical outcomes and neurobiological risk status were collected at 28 days or NICU discharge.

RESULTS

There was no intervention by time interaction (P = 0.60). There was a significant main effect of intervention (P = 0.03) between the sucrose plus pacifier group, and the standard care group (P = 0.01), but there was no main effect of time (P = 0.72). No group differences existed for adverse events, clinical outcomes, or neurobiological risk status.

DISCUSSION

Consistent management of painful procedures with sucrose plus pacifier was effective and safe for preterm neonates during their stay in the NICU. Further exploration of consistent pain management with sucrose on clinical, developmental, and neurobiological outcomes is required.

Factors associated with the psychological impact of severe acute respiratory syndrome on nurses and other hospital workers in Toronto

OBJECTIVES

A survey was conducted to measure psychological stress in hospital workers and measure factors that may have mediated acute traumatic responses.

METHODS

A self-report survey was completed by 1557 healthcare workers at three Toronto hospitals in May and June 2003. Psychological stress was measured with the Impact of Event Scale. Scales representing attitudes to the outbreak were derived by factor analysis of 76 items probing attitudes to severe acute respiratory syndrome. The association of Impact of Event Scale scores to job role and contact with severe acute respiratory syndrome patients was tested by analysis of variance. Between-group differences in attitudinal scales were tested by multivariate analysis of variance. Attitudinal scales were tested as factors mediating the association of severe acute respiratory syndrome patient contact and job role with total Impact of Event Scale by linear regression.

RESULTS

Higher Impact of Event Scale scores are found in nurses and healthcare workers having contact with patients with severe acute respiratory syndrome. The relationship of these groups to the Impact of Event Scale score is mediated by three factors: health fear, social isolation, and job stress.

CONCLUSIONS

Although distress in response to the severe acute respiratory syndrome outbreak is greater in nurses and those who care for patients with severe acute respiratory syndrome, these relationships are explained by mediating variables that may be available for interventions to reduce stress in future outbreaks. In particular, the data suggest that the targets of intervention should include job stress, social isolation, and health fear.

Patient Satisfaction and Pain Management

The importance of assessing and managing pain has become paramount in today's hospital environment. Poor pain management is associated with impaired health, decreased patient satisfaction, and increased healthcare costs. This quality improvement project on an internal medicine unit at an urban teaching hospital examined the impact of pain education on patient satisfaction with pain management. Although pain scores did not improve, there were improvements made with respect to patient assessment, patient satisfaction, and nursing knowledge.

Retaining and transferring nursing knowledge through a hospital internship program

In healthcare, organizations recognize that human capital is their most valuable asset. The importance of investing in knowledge workers is imperative given the current and future shortage of health professionals. Knowledge acquisition occurs through continuous learning and the transfer of information from those who are highly experienced to those who are less qualified. At St. Michael's Hospital, two innovative and unique programs were created for the transfer of knowledge. The first was a nurse fellowship program that enabled experienced nurses to spend two to three months learning new skills to advance clinical practice. The second was a nurse internship program in which new graduates spend three to four months in their area of hire to enhance clinical practice through skill development and prioritization of patient care needs. This paper describes both programs and presents an evaluation of the new-graduate internship program as an opportunity for professional development and career enhancement For nurse interns, the program promotes self-esteem and professional confidence, improves job satisfaction and rewards nurses for their contribution. For nurse preceptors, the program provides job enrichment, experience in teaching and recognition by the organization and peers that they are knowledge experts. In healthcare, organizations have come to acknowledge that their most valuable asset is human capital, in particular, knowledge workers (Horibe 1999). Knowledge workers contribute a composite of information, intellectual property and experience (Horibe 1999), acquired by study, investigation, observation or practice (Webster's Dictionary 1989). Investing in knowledge workers is investing in the future. In this regard, organizations have implemented recruitment and retention strategies to attract, retain and advance the highest calibre of health professional. Knowledge workers contribute to an organization through their ideas, analyses of complex situations and sound judgment in decision-making (Horibe 1999). They further develop these skills over the course of their career through continuous learning. This paper will focus on the importance of investing in nurses as knowledge workers. In particular, given the shortage of nurses and the reality that 25% of today's nurses can retire over the next 10 years (CNA 2001), it is imperative that knowledge transfer occur from highly experienced to less experienced nurses.

Supply and demand for cardiac nurses in Ontario: perceptions of CNOs

This article presents the results of a nursing survey of cardiac care hospitals undertaken by a Cardiac Care Network of Ontario Consensus Panel on Cardiovascular Human Resources. The focus of the Panel was to identify areas of current or pending shortages in human resources and make recommendations to the Ministry of Health and Long-Term Care about human resource management in adult cardiac care in Ontario. The article presents the number and mix of full-time, part-time and casual nursing staff, the age distribution of RNs, and the number of vacant Registered Nurse (RN) positions for a sample of cardiac care hospitals in Ontario. Next a sample of Chief Nursing Officer opinions about factors contributing to current difficulties in recruiting RNs and the outlook for future shortages are presented. Implications for nurse managers are offered, including development of new recruitment and retention strategies, identification of further efficiencies in care provision, and a need for nurse manager involvement in debates about the future of how health care is provided in Canada.

Creating a hospital-community infrastructure: challenges and benefits

With rising public expectations and demands for increased accountability, hospitals will be even more challenged by their local communities to implement strategies such as those developed at SMH to enable community participation that assists the hospital in serving its local population into the future. In response to unique health needs of its local community, SMH created an Inner City Health (ICH) Program in the early 1990s to provide comprehensive inpatient, ambulatory, and community outreach services. To build on its philosophy to reduce barriers to health for disadvantaged populations, the ICH Research Program, the only one of its kind in Canada, was also established. This paper will describe and explore the formalised infrastructure between SMH and the community; its evolution, as well as SMH's involvement with its community in context of the hospital's relationships with its Board of Directors, the Toronto teaching hospital system, media and advocacy groups. The role of ICH research in influencing evidence-based clinical practice, innovations in health science education and government policy will also be discussed as part of the SMH's hospital-community infrastructure.

The efficacy of developmentally sensitive interventions and sucrose for relieving procedural pain in very low birth weight neonates

BACKGROUND

Procedural pain management for very low birth weight (VLBW) neonates has been minimal or nonexistent in most neonatal intensive care units (NICUs).

OBJECTIVES

To compare the efficacy of developmentally sensitive behavioral interventions (nonnutritive sucking via a pacifier, positioning) and sucrose for relieving procedural pain in VLBW infants and to determine the influence of contextual factors (gestational age, postnatal age, birth weight, severity of illness, frequency of painful procedures) on pain response.

METHOD

In a prospective randomized crossover trial, pain was assessed in 122 VLBW neonates using the Premature Infant Pain Profile following four randomly ordered interventions during consecutive routine heel lance procedures.

RESULTS

Significant differences in pain existed among treatment interventions (F = 16.20, p < .0001). The pacifier with sucrose (F = 24.09, p < .0001) and pacifier with sterile water (F = 9.00, p = .003) significantly reduced pain. Prone positioning did not decrease pain (F = 2.24, p = .137). Frequency of painful procedures approached significance in influencing pain response (F = 3.59, p = .01).

CONCLUSIONS

The most efficacious interventions for reducing pain from single painful events were the pacifier with sucrose and the pacifier with sterile water. Research on the efficacy and safety of implementing these interventions, alone and in combination, for repeated painful procedures is needed. In addition, research is needed on the influence of implementing these interventions on pain response and clinical outcomes (e.g., health status and neurodevelopmental status) in VLBW neonates in the NICU.

Comparing nursing costs for preterm infants receiving conventional vs. developmental care

The incremental costs incurred by VLBW (less than 1,500 grams) infants during the first year of life accounted for one-third of the $11.4 billion spent in the U.S. on health care. Developmental care for VLBW infants focuses on light and noise management, coordination of interventions to minimize sleep interruptions and positioning/bundling the infant to prevent disorganizaiton and promote self-regulation. When compared to 60 VLBW infants receiving conventional NICU care, improved physiologic stability measures and fewer days in the NICU were recorded for the 60 VLBW infants cared for by nurses and trained developmental care specialists. Because the move from the NICU to the transitional unit occurred earlier for the developmental group of VLBW infants, and their nursing intensity needs were lower, the average cost savings achieved for this group was $4,340 per infant during the first 35 days of life or less if discharged.

Premature Infant Pain Profile: development and initial validation

OBJECTIVE

Inadequate assessment of pain in premature infants is a persistent clinical problem. The objective of this research was to develop and validate a measure for assessing pain in premature infants that could be used by both clinicians and researchers.

DESIGN

The Premature Infant Pain Profile (PIPP) was developed and validated using a prospective and retrospective design. Indicators of pain were identified from clinical experts and the literature. Indicators were retrospectively tested using four existing data sets.

PATIENTS AND SETTINGS

Infants of varying gestational ages undergoing different painful procedures from three different settings were utilized to develop and validate the measure.

METHODS AND RESULTS

The largest data set (n = 124) was used to develop the PIPP. The development process included determining the factor structure of the data, developing indicators and indicator scales and establishing internal consistency. The remaining three data sets were utilized to establish beginning construct validity.

CONCLUSIONS

The PIPP is a newly developed pain assessment measure for premature infants with beginning content and construct validity. The practicality and feasibility for using the PIPP in clinical practice will be determined in prospective research in the clinical setting.

Developmental versus conventional care: a comparison of clinical outcomes for very low birth weight infants

The purpose of this research was to describe the clinical profile of very low birth weight (VLBW) infants receiving conventional versus developmental care during their hospitalization and to determine the appropriateness of developmental-care interventions. A phase-lag study with 124 preterm infants indicated that although there were no significant differences in individual clinical outcomes, developmental care had a significant effect on the physiologic stability of the infant over time. Developmental interventions were used for all infants receiving the developmental-care intervention, with varying frequency.

Outcomes management in neonatal nursing clinical practice

One approach for evaluating the quality and cost of patient care is through outcomes management. Outcomes management in a neonatal environment will be described within a structure-process-outcome framework. Outcomes will be presented from three perspectives: administrative, economic and clinical. The relevance and implications of outcomes management will be discussed.

Outcomes monitoring: adjusting for risk factors, severity of illness, and complexity of care

Adjusting for risk factors, severity of illness, and complexity of care is important when comparing and interpreting outcomes. Current and future approaches for examining risk factors, severity of illness, and complexity of care are described within the contexts of administrative, economic, and clinical outcomes. Reasons why the current standardized instruments, computerized severity systems, and workload/intensity measurements, when used alone, are inadequate for outcomes monitoring are proposed. A more comprehensive model for outcomes monitoring is required, one that adjusts outcomes for risk factors, severity of illness, and complexity of care.

Investigation of Newborn Hyperbilirubinemia: Helping family physicians indentify newborns at risk

The trend to early neonatal discharge underscores the need to detect and manage neonatal hyperbilirubinemia. In a retrospective study, 84 charts from newborns were audited for clinical hyperbilirubinemia. Jaundice was recorded for 29% of the newborns, 92% of cases appearing after the second day. Audits of additional 257 charts indicated that neonates delivered by cesarean section were twice as likely to develop jaundice.

The statistical analysis of matched data in psychiatric research

Clinical studies in psychiatry frequently involve the analysis of matched pairs, in which each patient is matched with his or her psychiatric clinician. If the response variable of interest is dichotomous, then McNemar's chi 2 test for correlated proportions may be applied to the resulting data. However, this test assumes that the set of matched pairs are statistically independent, an assumption that is violated if some clinicians are matched with more than one patient. In this article we present alternatives to McNemar's test for dealing with this problem.
