Determining the influence of the primary and specialist network of care on patient and system outcomes among patients with a new diagnosis of chronic obstructive pulmonary disease (COPD).

INTRODUCTION: Care for patients with chronic obstructive pulmonary disease (COPD) is provided by both family physicians (FP) and specialists. Ideally, patients receive comprehensive and coordinated care from this provider team. The objectives for this study were: 1) to describe the family and specialist physician network of care for Ontario patients newly diagnosed with COPD and 2) to determine the associations between selected characteristics of the physician network and unplanned healthcare utilization. METHODS: We conducted a retrospective cohort study using Ontario health administrative data housed at ICES (formerly the Institute for Clinical Evaluative Sciences). Ontario patients, ≥ 35 years, newly diagnosed with COPD were identified between 2005 and 2013. The FP and specialist network of care characteristics were described, and the relationship between selected characteristics (i.e., continuity of care) with unplanned healthcare utilization during the first 5 years after COPD diagnosis were determined in multivariate models. RESULTS: Our cohort consisted of 450,837 patients, mean age 61.5 (SD 14.6) years. The FP was the predominant provider of care for 86.4% of the patients. Using the Bice-Boxerman's Continuity of Care Index (COCI), a measure reflecting care across different providers, 227,082 (50.4%) were categorized in a low COCI group based on a median cut-off. In adjusted analyses, patients in the low COCI group were more likely to have a hospital admission (OR = 2.27, 95% CI 2.20,2.22), 30-day readmission (OR = 2.44, 95% CI 2.39, 2.49) and ER visit (OR = 2.27, 95% CI 2.25, 2.29). CONCLUSION: Higher indices of continuity of care are associated with reduced unplanned hospital use for patients with COPD. Primary care-based practice models to enhance continuity through coordination and integration of both primary and specialist care have the potential to enhance the health experience for patients with COPD and should be a health service planning priority.

What do primary care providers think about implementing breast cancer survivorship care?

Purpose: As cancer centres move forward with earlier discharge of stable survivors of early-stage breast cancer (bca) to primary care follow-up, it is important to address known knowledge and practice gaps among primary care providers (pcps). In the present qualitative descriptive study, we examined the practice context that influences implementation of existing clinical practice guidelines for providing such care. The purpose was to determine the challenges, strengths, and opportunities related to implementing comprehensive evidence-based bca survivorship care guidelines by pcps in southeastern Ontario. Methods: Semi-structured interviews were conducted with 19 pcps: 10 physicians and 9 nurse practitioners. Results: Thematic analysis revealed 6 themes within the broad categories of knowledge, attitudes, and resources. Participants highlighted 3 major challenges related to providing bca survivorship care: inconsistent educational preparation, provider anxieties, and primary care burden. They also described 3 major strengths or opportunities to facilitate implementation of survivorship care guidelines: tools and technology, empowering survivors, and optimizing nursing roles. Conclusions: We identified several important challenges to implementation of comprehensive evidence-based survivorship care for bca survivors, as well as several strengths and opportunities that could be built upon to address those challenges. Findings from our research could inform targeted knowledge translation interventions to provide support and education for pcps and bca survivors.

Does oral carbohydrate supplementation improve labour outcome? A systematic review and individual patient data meta-analysis.

BACKGROUND: Labour is a period of significant physical activity. The importance of carbohydrate intake to improve outcome has been recognised in sports medicine and general surgery. OBJECTIVES: To assess the effect of oral carbohydrate supplementation on labour outcomes. SEARCH STRATEGY: MEDLINE (1966-2014), Embase, the Cochrane Library and clinical trial registries. SELECTION CRITERIA: Randomised controlled trials (RCT) of women randomised to receive oral carbohydrate in labour (<6 cm dilated), versus placebo or standard care. DATA COLLECTION AND ANALYSIS: Authors were contacted to provide data. Individual patient data meta-analyses were performed to calculate pooled risk ratios (RR) and 95% confidence intervals (CI). MAIN RESULTS: Eight RCTs met the inclusion criteria. Six authors responded, four supplied data (n = 691). Three studies used isotonic drinks (one placebo-controlled, two compared with standard care), and one an advice booklet regarding carbohydrate intake. The mean difference in energy intake between the intervention and control groups was small [three studies, 195 kilocalories (kcal), 95% CI 118-273]. There was no difference in the risk of caesarean section (RR 1.15, 95% CI 0.83- 1.61), instrumental birth (RR 1.26, 95% CI 0.96-1.66) or syntocinon augmentation (RR 0.99, 95% CI 0.86-1.13). Length of labour was similar (mean difference -3.15 minutes, 95% CI -35.14 to 41.95). Restricting the analysis to primigravid women did not affect the result. Oral carbohydrates did not increase the risk of vomiting (RR 1.09, 95% CI 0.78-1.52) or 1-minute Apgar score <7 (RR 1.23, 95% CI 0.82-1.83). AUTHORS' CONCLUSION: Oral carbohydrate supplements in small quantities did not alter labour outcome. TWEETABLE ABSTRACT: Oral carbohydrate does not affect labour. But the difference between intervention and control equals 10 teaspoons sugar.

A cross-sectional study of shift work, sleep quality and cardiometabolic risk in female hospital employees.

OBJECTIVES: Investigating the potential pathways linking shift work and cardiovascular diseases (CVD), this study aimed to identify whether sleep disturbances mediate the relationship between shift work and the metabolic syndrome, a cluster of CVD risk factors. DESIGN: Cross-sectional study. SETTING: A tertiary-level, acute care teaching hospital in Southeastern Ontario, Canada. PARTICIPANTS: Female hospital employees working a shift schedule of two 12 h days, two 12 h nights, followed by 5 days off (n=121) were compared with female day-only workers (n=150). PRIMARY AND SECONDARY OUTCOME MEASURES: Each of the seven components of the Pittsburgh Sleep Quality Index (PSQI) was measured. Of these, PSQI global score, sleep latency and sleep efficiency were examined as potential mediators in the relationship between shift work and the metabolic syndrome. RESULTS: Shift work status was associated with poor (>5) PSQI global score (OR=2.10, 95% CI 1.20 to 3.65), poor (≥2) sleep latency (OR=2.18, 95% CI 1.23 to 3.87) and poor (≥2) sleep efficiency (OR=2.11, 95% CI 1.16 to 3.84). Although shift work was associated with the metabolic syndrome (OR=2.29, 95% CI 1.12 to 4.70), the measured components of sleep quality did not mediate the relationship between shift work and the metabolic syndrome. CONCLUSIONS: Women working in a rapid forward rotating shift pattern have poorer sleep quality according to self-reported indicators of the validated PSQI and they have a higher prevalence of the metabolic syndrome compared with women who work during the day only. However, sleep quality did not mediate the relationship between shift work and the metabolic syndrome, suggesting that there are other psychophysiological pathways linking shift work to increased risk for CVD.

Further clinical validation of the walking impairment questionnaire for classification of walking performance in patients with peripheral artery disease.

The purpose of this study was to further validate the Walking Impairment Questionnaire (WIQ) as a self-report tool to aid in the clinical identification of walking ability of patients with peripheral artery disease (PAD). 132 patients with PAD and an ankle brachial index (ABI) ≤0.90 were enrolled; 123 provided complete data for the WIQ and standardized graded treadmill test. The WIQ scores were consistent with reported scores in other studies. The absolute claudication distance (ACD) ranged from 42.3 to 1589.2 meters; the peak walking time (PWT) ranged from 68 to 1800 seconds. Adjusted WIQ scores were positively and moderately associated with the log transformed ACD and PWT (r > .53, P < .001). Based on the area under the curve analysis, an overall WIQ score of 42.5 or less identified low performers (sensitivity 0.90, specificity 0.73); the combined subscale score of distance and stair of 75.5 or more identified high performers (sensitivity 0.41, specificity 0.90). We conclude that WIQ cut-offs appropriately classify walking performance in PAD patients, making this a potentially useful clinical tool. Consideration needs to be given to incorporating a standardized WIQ version into practice guidelines and the use of innovative strategies to facilitate clinical uptake.

The prevalence of chronic pain and pain-related interference in the Canadian population from 1994 to 2008.

INTRODUCTION: Estimates of the prevalence of chronic pain worldwide and in Canada are inconsistent. Our primary objectives were to determine the prevalence of chronic pain by sex and age and to determine the prevalence of pain-related interference for Canadian men and women between 1994 and 2008. METHODS: Using data from seven cross-sectional cycles in the National Population Health Survey and the Canadian Community Health Survey, we defined two categorical outcomes, chronic pain and pain-related interference with activities. RESULTS: Prevalence of chronic pain ranged from 15.1% in 1996/97 to 18.9% in 1994/95. Chronic pain was most prevalent among women (range: 16.5% to 21.5%), and in the oldest (65 years plus) age group (range: 23.9% to 31.3%). Women aged 65 years plus consistently reported the highest prevalence of chronic pain (range: 26.0% to 34.2%). The majority of adult Canadians who reported chronic pain also reported at least a few activities prevented due to this pain (range: 11.4% to 13.3% of the overall population). CONCLUSION: Similar to international estimates, this Canadian population-based study confirms that chronic pain persists and impacts daily activities. Further study with more detailed definitions of pain and pain-related interference is warranted.

Reproducibility of a task description questionnaire for working pregnant women.

The objective of this study was to evaluate the reproducibility of a Task Description Questionnaire that was designed to investigate exposures to, and influential factors for, problematic tasks experienced by working pregnant women. The questionnaire comprised questions concerning 22 task components (covering working posture, manual material handling, work pace, prolonged postures and others), eight influential factors contributing to problematic tasks, discomfort (measured using a body map) and level of effort to perform the tasks. Reproducibility of the questionnaire was assessed by interviewing participants on two occasions one week apart for interviews at both 20 and 34 weeks of pregnancy. Eleven and 13 problematic tasks were reported by 21 working pregnant women at 20 and 34 weeks of pregnancy, respectively. These tasks were surveyed using the Task Description Questionnaire. Kappa statistics and correlation coefficients (supplemented by paired t-tests) were used to examine the reproducibility of responses to the questionnaire. The results showed that most of the variables were measured with very good or satisfactory reproducibility. The reproducibility of exposure to work posture was higher than that of exposure to manual material handling. There was no significant difference between test and retest means for the discomfort scores measured on the body map, except for the maximum discomfort score for the whole body in the 34 weeks survey. The study suggests that the questionnaire can be reliably used in the study of problematic tasks experienced by pregnant women. But an initial preview of the questions by the subjects and explanation of the questions given to the subjects by the interviewer may help to produce more reliable results.

Analysis of self-reported problematic tasks for pregnant women.

The objective of this study was to identify major components of, and influential factors in, problematic tasks performed by pregnant women employed in education, health care and service areas. Seventy-two pregnant women were surveyed using specially designed questionnaires consisting of an Initial Survey, a Job Analysis Questionnaire and a Task Description Questionnaire. Forty-four subjects (60%) had difficulty performing at least one work task and reported 105 tasks that were problematic at work. Reaching above the head, bending forward, bending and twisting, pushing, repeating actions and working at a fast pace were identified as the task components requiring the greatest level of effort. Excessive effort, excessive time, getting tired, repetitive actions, stress and fear of injury were identified as factors that had strong associations with the six major task components. Findings of this study suggest that these task components and factors should be considered when designing, assigning or analysing tasks for working pregnant women.

The effect of staff nurse participation in a clinical nursing research project on attitude towards, access to, support of and use of research in the acute care setting.

The purpose of this study was to determine the effect of participation in research on staff nurses' attitude towards, access to, perceived support of and reported use of research in practice. Six medical surgical units in a southeastern Ontario teaching hospital were randomly assigned to receive 3 different levels of exposure to research: high, low and usual. On the high participation units, a clinical research group consisting of the investigator and interested nurses (n = 18) critiqued research literature related to an important clinical issue (i.e., patterns of sleep) and designed and implemented a clinical research study. On the low participation units, a similar clinical research group (n = 10) met once and were involved, solely, in the design and implementation of the clinical research protocol. On the control units, there were no formalized research groups or activities. All registered nurses (n = 235), including the research group participants, on the 6 units were surveyed with a research utilization questionnaire (RUQ) pre and post participant intervention. The RUQ scores were higher on the high participation units at baseline and post intervention in comparison to the low and control units. Nurses who participated directly in the clinical research groups (high and low) reported similar RUQ scores post intervention and higher scores in comparison to all nurses. All RUQ scores were higher post intervention. Nurses with clinical expertise but minimal research expertise participated meaningfully in clinical research. While participation had an individual effect there was no unit effect, suggesting other factors, such as organizational support and culture, are important determinants of research use.

The 2000 Helene Hudson Memorial Lecture. Decisional role in seriously ill hospitalized patients near the end of life: the patient's and provider's perspective.

Decisions about whether or not to implement life-sustaining therapies are complex and are becoming more so as the ability to prolong life with advanced technologies and care increases. The objectives of this study were: (1) to determine seriously ill hospitalized patients' preferences for decisional role with respect to decisions about life-sustaining treatments, and (2) to determine if providers were aware of patients' preferences. This prospective, descriptive pilot study was conducted at an Ontario teaching hospital. One hundred and seventeen seriously ill adult patients admitted with cancer and non-cancerous conditions participated in a structured interview. Fifty-three nurses and 63 physicians responsible for the care of the participating patients also participated. Patients and providers were asked similar questions about end-of-life discussions and preference for decisional responsibility for life-sustaining treatments. Most patients (n = 89, 77%) had thought about end-of-life issues and were willing to discuss these with their physicians and nurses, but few (n = 37, 37%) reported such discussions. Preferences for decisional role varied; most indicated a preference for a shared role (n = 80, 80%) and there were no differences in patients with or without cancer. Generally, both physicians and nurses were not aware of or did not determine accurately patient preferences for decisional role. The findings from this study show that seriously ill hospitalized patients have thought about and are willing to share in discussions about end-of-life care with their providers, yet many have not.

Measuring family satisfaction with care in the intensive care unit: the development of a questionnaire and preliminary results.

PURPOSE: To develop and test the feasibility of administering a questionnaire to measure family members' level of satisfaction with care provided to them and their critically ill relative. MATERIALS AND METHODS: To develop the questionnaire, existing conceptual frameworks of patient satisfaction, decision making, and quality of end-of-life care were used to identify important domains and items. We pretested the questionnaire for readability, clarity, and sensibility in 21 family members and 16 professionals. To assess validity, we measured the correlation between satisfaction with overall care and satisfaction with decision making. To assess the reliability of the questionnaire, we administered the questionnaire to next of kin of surviving patients on discharge and 7 to 10 days later. RESULTS: Questionnaires were mailed out to 33 family members of nonsurvivors; 24 were returned completed but only 22 (66%) were usable.Twenty-five family members of eligible surviving critically ill patients participated in the test-retest part of this study. Of the 47 respondents, 84% were very satisfied with overall care and 77% were very satisfied with their role in the decision making. There was good correlation between satisfaction with overall care and satisfaction with decision making (correlation coefficient =.64). The assessment of overall satisfaction with care was shown to be reliable (correlation coefficient =.85). CONCLUSIONS: This questionnaire has some measure of reliability and validity and is feasible to administer to next of kin of critically ill patients.

Long-term health-related quality of life in survivors of sepsis. Short Form 36: a valid and reliable measure of health-related quality of life.

OBJECTIVE: To describe the long-term health-related quality of life (HRQL) of survivors of sepsis and to evaluate the reliability and validity of the medical outcomes study Short Form-36 (SF-36) in this population. STUDY DESIGN: Cross-sectional survey. SETTING: University intensive care unit. PATIENTS: Surviving patients over the age of 17 yrs who met the criteria for the Society of Critical Care Medicine/American College of Chest Physicians definition of sepsis identified through a review of patients admitted to the intensive care unit from 1994 to 1998. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Baseline demographics and clinical characteristics were abstracted from the medical chart. After hospital discharge, the SF-36 and Patrick's Perceived Quality of Life scale were administered by telephone. The SF-36 was readministered 2 wks later. We screened the charts of 109 patients; 78 had a diagnosis of sepsis. Of these, 31 had died, 3 had severe communication problems, 9 refused to participate, and 5 patients could not be located. A total of 30 patients completed the first interview; 26 completed the second. Compared with established norms for the U.S. general population, survivors of sepsis scored significantly lower on the physical functioning, role physical, general health, vitality, and social functioning domains, as well as on the Physical Health Summary Scale. Mean scores on the Mental Health Summary Scale were very similar between the survivors of sepsis and U.S. norms. The SF-36 demonstrated high internal consistency (Cronbach's alpha ranged from 0.65 to 0.94) and excellent test-retest stability (intraclass correlation coefficient ranged from 0.75 to 0.97). Both the Physical Health Summary Scale and the Mental Health Summary Scale correlated well with overall Perceived Quality of Life scores (Pearson correlation coefficients 0.45 and 0.56, respectively). CONCLUSIONS: The long-term HRQL of survivors of sepsis is significantly lower than that of the general U.S. population. The SF-36 demonstrated good reliability and validity when used to measure HRQL in survivors of sepsis.

Dying in Canada: is it an institutionalized, technologically supported experience?

Although preliminary evidence shows that people generally prefer to die at home, very little is known about where Canadians die. Understanding the epidemiology of dying in Canada may illuminate opportunities to improve quality of end-of-life care and related health policy. We conducted a cross-sectional analysis of death records in Canada to determine the proportions of deaths occurring in hospitals and special care units. Our analysis found that deaths in Canada occur in hospitals with provincial and territorial proportions ranging from 87% in Quebec to 52% in the Northwest Territories. In hospitals recording deaths in special care units, 18.64% of all deaths occurred in special care units. The proportion of deaths in special care units ranged from 25% in Manitoba to 7% in the Northwest Territories. The proportion of deaths in special care units varied by size and nature (teaching vs. non-teaching) of hospitals. It increased with the size of the hospital from 8% in hospitals with 1-49 beds, to 23% for hospitals with 400 or more beds. In teaching hospitals, 27% of deaths occurred in special care units, and in non-teaching hospitals the proportion was 15%. In conclusion, the majority of deaths in Canada occur in hospitals and a substantial proportion occur in special care units, raising questions about the appropriateness and quality of current end-of-life care practices in Canada.

End-of-life decision making in the seriously ill hospitalized patient: an organizing framework and results of a preliminary study.

Recent studies of patient/family satisfaction with end-of-life care suggest that improvements in communication and decision making are likely to have the greatest impact on improving the quality of end-of-life care. The apparent failure of recent studies specifically designed to improve decision making strongly suggest that there are powerful determinants of the decision making process that are not completely understood. In this paper, we present an organizing framework that describes the decision making process and breaks it into three analytic steps: information exchange, deliberation, and making the decision. In addition, we report the results of a preliminary study of end-of-life decision making that incorporates aspects of this organizing framework. Thirty-seven seriously ill hospitalized patients were interviewed. The majority wanted to share decisional responsibility with physicians. We demonstrated the feasibility of measuring certain aspects of the decision making process in such patients. By providing and using a framework related to end-of-life decision making, we hope to better understand the complex interaction and processes between dying patients, caregivers, and physicians.

Who knows best: the patient or the provider? A nursing perspective.

Who knows best: the patient or the provider? My opinion, based on a review of the literature and practical experience, is that the patient, the provider and the system each offer a unique perspective that we can draw upon in ensuring quality care across the continuum. Nurses have a unique body of knowledge and skill that they bring to each interaction with the patient. They must have an awareness of the patient's and the system's expectations and interact and negotiate realistic expectations for each. The maintenance of balanced expectations and the measurement of effectiveness will continue to be a challenge. However, patients should be involved in and direct aspects of their care and feel satisfied with the process. Ultimately, nurses and the hospitals in which they work are responsible for providing effective and satisfying care. I would like to end by reinforcing the importance of the patient's voice in the provision of compassionate care. It is disheartening to read about patients' experiences of "discompassionate healthcare" (Holloway 1999). Yet I am reassured when I read or experience examples of compassionate and effective care such as that outlined by Valerie McDonald. (Hospital Quarterly Winter 1999/2000) Ms. McDonald, a former social worker and adult educator, is the mother of three daughters, one who had Burkitt's lymphoma diagnosed in 1994 and a second who had acute lymphostatic leukemia diagnosed in 1997 and who died recently in 1999. McDonald provided a wonderful perspective about her hospital experiences--the good and the bad. There would be no denying from this report that patients know the key qualities necessary for effective and compassionate care and that this mother recognized the energy and time it took to provide this care. "I hope," she states, "as the dust settles from restructuring and cutbacks that hospital staff will still have the time, energy and flexibility to practice the art of healing as they did with my children" (p. 24). I too reinforce that we must ensure nurses (and others) have the resources, the flexibility within their roles and the knowledge and skill to practise both the art and science of nursing.

Fetal responses to maternal strength conditioning exercises in late gestation.

Cardiovascular responses to strength conditioning exercises were examined in 12 healthy pregnant women and their unborn fetuses during the third trimester. A group of 12 healthy nonpregnant women of similar ages, parity, body height, and pre-pregnant body mass was also studied. Maternal heart rate and blood pressure and fetal heart rate (FHR) responses were measured in both the supine (30 degrees tilt) and seated postures during handgrip (HG), single-leg extension (SL), and double-leg extension (DL) exercise. Subjects performed 3 sets of 10 reps at 50, 70, and 90% of their 10-repetition maximum (10-RM) for each exercise in both postures. Pregnant subjects exhibited higher heart rates but similar blood pressure responses to control subjects under all experimental conditions. Significant increases were observed for the frequency of FHR accelerations (0.10 to 0.27/min) from rest to DL in the sitting posture at 90% RM. Moderate fetal bradycardia was observed occasionally in the tilted supine posture at rest and both during (SL, DL) and following (HG, SL, DL) exercise, suggesting that this posture should be avoided in late gestation. The results support the safety of moderate strength conditioning exercises in healthy pregnancy.

The emergence of a culture that promotes evidence based clinical decision making within an acute care setting.

Nursing research programs within acute care hospitals are essential to the development and integration of nursing knowledge, difficult to implement and rarely evaluated. The purpose of this paper is three fold: (1) to describe the development, structures, and processes of a nursing research program within an acute care teaching hospital and (2) to describe selected evaluation outcomes and (3) to discuss future directions.

A survey of variables related to research utilization in nursing practice in the acute care setting.

Support from the work environment, attitude of nurses and availability of research findings are variables that influence the use of research in clinical practice. Acknowledging the importance of these variables in obtaining the goal of evidence based nursing practice, a nursing department of an acute care hospital determined that exploring these variables in its own setting was important to the successful planning of research education and utilization initiatives. This study describes the extent of selected factors (research support and availability, and attitude towards research) in relation to research utilization within this nursing department and based on the findings, suggests a number of ways nurse administrators can support research utilization, promote positive attitudes towards research and enhance availability of research findings in practice.

Swaddling after heel lance: age-specific effects on behavioral recovery in preterm infants.

We examined responses of preterm infants to swaddling after a heel lance. Fifteen preterm infants from two postconceptional age (PCA) groups (Group 1: n = 7, PCA < 31 wk; Group 2: n = 8, PCA > or = 31 wk) were observed for 30 minutes during blood sampling followed by routine care; blood sampling followed by swaddling; and no blood sampling and routine care. In both groups, blood sampling resulted in concurrent increases in heart rate and state of arousal, in negative facial displays, and in reductions in blood oxygensaturation. After the blood was drawn, infants less than 31 weeks PCA exhibited an immediate and spontaneous return to behavioral patterns similar to those observed during the no-blood-sample condition, regardless of treatment condition. Infants 31 weeks PCA or older exhibited protracted behavioral disturbance that was significantly reduced by the use of swaddling. We discuss the significance of these findings.

A nursing research utilization strategy for staff nurses in the acute care setting.

The importance of research-based nursing practice is well recognized. However, typically, strategies to incorporate research findings into nursing practice have not been evaluated in terms of staff nurse outcomes. Thus, the purpose of this project was to evaluate the effectiveness of a research utilization strategy for staff nurses in the neonatal intensive care unit of a community teaching hospital. This project was intended to serve as a model for the incorporation of research findings into nursing practice on other nursing units in the acute care setting.
