More-2-Eat implementation demonstrates that screening, assessment and treatment of malnourished patients can be spread and sustained in acute care; a multi-site, pretest post-test time series study.

BACKGROUND: Malnutrition in medical and surgical inpatients is an on-going problem. More-2-Eat (M2E) Phase 1 demonstrated that improved detection and treatment of hospital malnutrition could be embedded into routine practice using an intensive researcher-facilitated implementation process. Yet, spreading and sustaining new practices in diverse hospital cultures with minimal researcher support is unknown. AIMS: To demonstrate that a scalable model of implementation can increase three key nutrition practices (admission screening; Subjective Global Assessment (SGA); and medication pass (MedPass) of oral nutritional supplement) in diverse acute care hospitals to detect and treat malnutrition in medical and surgical patients. METHODS: Ten hospitals participated in this pretest post-test time series implementation study from across Canada, including 21 medical or surgical units (Phase 1 original units (n = 4), Phase 1 hospital new units (n = 9), Phase 2 new hospitals and units (n = 8)). The scalable implementation model included: training champions on implementation strategies and providing them with education resources for teams; creating a self-directed audit and feedback process; and providing mentorship. Standardized audits of all patients on the study unit on an audit day were completed bi-monthly to track nutrition care activities since admission. Bivariate comparisons were performed by time period (initial, mid-term and final audits). Run-charts depicted the trajectory of change and qualitatively compared to Phase 1. RESULTS: 5158 patient charts were audited over the course of 18-months. Admission nutrition screening rates increased from 50% to 84% (p < 0.0001). New Phase 1 units more readily implemented screening than Phase 2 sites, and the original Phase 1 units generally sustained screening practices from Phase 1. SGA was a sustained practice at Phase 1 hospitals including in new Phase 1 units. The new Phase 2 units improved completion of SGA but did not reach the levels of Phase 1 units (original or new). MedPass almost doubled over the time periods (7%-13% of all patients p < 0.007). Other care practices significantly increased (e.g. volunteer mealtime assistance). CONCLUSION: Nutrition-care activities significantly increased in diverse hospital units with this scalable model. This heralds the transition from implementation research to sustained changes in routine practice. Screening, SGA, and MedPass can all be implemented, improve nutrition care for all patients, spread within an organization, and for the most part, sustained (and in the case of original Phase 1 units, for over 3 years) with champion leadership.

Handgrip strength predicts length of stay and quality of life in and out of hospital.

BACKGROUND: Handgrip strength (HGS) is a practical measure of strength and physical function that can be used to identify frailty among hospitalized patients, but its utility in this setting is unclear. To be considered useful, any functional measure needs to provide pertinent information on the patient and predict relevant outcomes such as health-care utilization (e.g., length of stay (LOS)) and patient-reported quality of life (QOL). The purpose of this study was to determine if HGS predicted LOS and QOL. A second aim was to examine the best sensitivity (SE) and specificity (SP) for predicting length of stay (>7 or >13 days) using previously published cut-points for HGS. METHODOLOGY: HGS was measured on 1136 medical patients shortly after admission with a Lafayette dynamometer. QOL was assessed with the self-reported SF-12 completed with an interviewer during hospitalization and 30- days after discharge via telephone. Physical (PCS) and mental (MCS) component scores of SF-12 were calculated. A variety of covariates were assessed (e.g., nutritional status). Multivariate analyses stratified by sex were completed. RESULTS: The mean LOS was 12.71 days (median = 8.00; SD = 13.20), 12.88 days (SD = 13.82) for males, and 12.58 days (SD = 12.68) for females. Lower admission HGS scores were associated with longer LOS (male X2 = 7.85, p < 0.05; female X2 = 14.9, p < 0.0001). The average quality of life scores were as follows: in hospital PCS: 34.66, MCS: 46.49; post discharge PCS: 36.17; MCS: 51.22. HGS predicted PCS during hospitalization (male X2 = 36.22, p < 0.0001; female X2 = 19.87, p < 0.0001) and post hospitalization (male X2 = 6.98, p < 0.01; female X2 = 10.99, p < 0.01). Various reference cut-points for HGS were tested against LOS, with none being considered appropriate (e.g., SE and SP both < 70) when adjusting for age and sex. CONCLUSION: Admission HGS adds predictive value for both LOS and physical components of QOL and is worth pursuing in practice to identify potential frailty and the need for proactive steps to mitigate further functional decline during hospitalization. However, HGS cut-points for LOS specific to acute care patients need to be defined and tested.

Multi-site implementation of nutrition screening and diagnosis in medical care units: Success of the More-2-Eat project.

BACKGROUND: Improving the detection and treatment of malnourished patients in hospital is needed to promote recovery. AIM: To describe the change in rates of detection and triaging of care for malnourished patients in 5 hospitals that were implementing an evidence-based nutrition care algorithm. To demonstrate that following this algorithm leads to increased detection of malnutrition and increased treatment to mitigate this condition. METHODS: Sites worked towards implementing the Integrated Nutrition Pathway for Acute Care (INPAC), including screening (Canadian Nutrition Screening Tool) and triage (Subjective Global Assessment; SGA) to detect and diagnose malnourished patients. Implementation occurred over a 24-month period, including developmental (Period 1), implementation (Periods 2-5), and sustainability (Period 6) phases. Audits (n = 36) of patient health records (n = 5030) were conducted to identify nutrition care practices implemented with a variety of strategies and behaviour change techniques. RESULTS: All sites increased nutrition screening from Period 1, with three achieving the goal of 75% of admitted patients being screened by Period 3, and the remainder achieving a rate of 70% by end of implementation. No sites were conducting SGA at Period 1, and sites reached the goal of a 75% completion rate or referral for those identified to be at nutrition risk, by Period 3 or 4. By Period 2, 100% of patients identified as SGA C (severely malnourished) were receiving a comprehensive nutritional assessment. In Period 1, the nutrition diagnosis and documentation by the dietitian of 'malnutrition' was a modest 0.37%, increasing to over 5% of all audited health records. The overall use of any Advanced Nutrition Care practices increased from 31% during Period 1 to 63% during Period 6. CONCLUSION: The success of this multi-site study demonstrated that implementation of nutrition screening and diagnosis is feasible and leads to appropriate care. INPAC promotes efficiency in nutrition care while minimizing the risk of missing malnourished patients.

Handgrip Strength, but Not 5-Meter Walk, Adds Value to a Clinical Nutrition Assessment.

BACKGROUND: Decreased physical functioning is associated with malnutrition and common in acute care patients; determining loss of function is often considered part of a comprehensive nutrition assessment. Handgrip strength (HGS) and 5-meter timed walk (5m) are functional measures used in a variety of settings. This analysis sought to determine which functional measure could be added to a hospital nutrition assessment, based on its feasibility and capacity to discriminate patient subgroups. METHODS: Eligible medical patients (no delirium/dementia, admitted from community; n = 1250), recruited from 5 hospitals that participated in a previous multisite action research study, provided data on demographics, HGS, 5m, nutrition status, perceived disability, and other characteristics. RESULTS: Significantly more patients (z = 17.39, P < .00001) were able to complete HGS than 5m (92% versus 43%, respectively). Median HGS was 28.0 kg for men and 14.7 kg for women. Of patients who completed the 5m, mean completion time was 8.98 seconds (median, 6.79 seconds, SD = 6.59). 5m and HGS scores were significantly worse with patient-perceived disability (z = -9.56, t = 10.69, respectively; P < .0001; 95% confidence interval [CI], [7.33, 10.63]; [1.76, 3.18]). HGS was associated with nutrition status (t = 4.13, P < .001; 95% CI [2.02, 5.67]), although it showed poor validity as a single nutrition indicator. CONCLUSIONS: These data indicate that HGS is a more useful functional measure than 5m when added to a hospital nutrition assessment. Determination of HGS cutpoints to identify low strength in acute care patients will promote its use.

Improving the standard of nutrition care in hospital: Mealtime barriers reduced with implementation of the Integrated Nutrition Pathway for Acute Care.

BACKGROUND: Poor food intake is common in hospital patients and is associated with adverse patient and healthcare outcomes; diverse mealtime barriers to intake often undermine clinical nutrition care. AIM: This study determines whether implementation of locally adaptable nutrition care activities as part of uptake of the Integrated Nutrition Pathway for Acute Care (INPAC) reduced mealtime barriers and improved other patient outcomes (e.g. length of stay; LOS) when considering other covariates. METHODS: 1250 medical patients from 5 Canadian hospitals were recruited for this before-after time series design. Mealtime barriers were tallied with the Mealtime Audit Tool after a meal, while proportion of the meal consumed was assessed with the My Meal Intake Tool. Implementation of new standard care activities occurred over 12 months and three periods (pre-, early, and late) of implementation were compared. Regression analyses determined the effect of time period while adjusting for key covariates. RESULTS: Mealtime barriers were reduced over time periods (Period 1 = 2.5 S.D. 2.1; Period 3 = 1.8 S.D. 1.7) and site differences were noted. This decrease was statistically significant in regression analyses (-0.28 per time period; 95% CI -0.44, -0.11). Within and across site changes were also observed over time in meal intake and LOS; however, after adjusting for covariates, time period of implementation was not significantly associated with these outcomes. DISCUSSION: Mealtime barriers can be reduced and sustained by implementing improved standard care procedures for patients. The More-2-Eat study provides an example of how to implement changes in practice to support the prevention and treatment of malnutrition.

Low food intake in hospital: patient, institutional, and clinical factors.

In-hospital malnutrition and inadequate food intake have been associated with negative outcomes (e.g., prolonged length of stay, readmission, mortality, and increased hospital costs). Studies examining the factors associated with low food intake in hospital, commonly defined as the consumption of ≤50% of meals, have produced mixed results. We examined the correlates of food intake including patient socioeconomic, demographic, and health characteristics, institutional factors, and common clinical strategies in 1129 medical patients from 5 Canadian hospitals. Low food intake was found in 35% of patients (41% of females and 29% of males) (p < 0.001). In multivariate analyses, sex, socioeconomic status, demographics, and diagnoses were not significantly related to food intake. Patients assessed as malnourished (subjective global assessment (SGA) B/C) (odds ratio (OR), 2.41; p = 0.003) or as not at risk of malnutrition (OR, 1.67; p = 0.040) were more likely to have low intake when compared with those assessed as well nourished (SGA A). Patient reports of mealtime challenges (OR, 2.70; p < 0.001) and barriers to food intake (OR, 1.11; p = 0.008) were positively related to low intake throughout the study sample. Higher 12-Item Short Form Health Survey Mental Component Summary scores were related to better food intake (OR, 0.98; p < 0.001). Clinical strategies such as between-meal snacks lowered the likelihood of low food intake (OR, 0.55; p = 0.037), whereas a group of "other strategies" increased the odds (OR, 2.77; p = 0.001). These results offer a better understanding of the correlates of in-hospital low food intake. The conclusion discusses some avenues for improving food intake in the clinical setting, such as better mealtime monitoring and a reduction in barriers to food intake.

An economic perspective on the causal explanations for the socioeconomic inequalities in health

[ABSTRACT]. Socioeconomic inequality, or the socioeconomic status (SES) gradient, is arguably one of the most-studied phenomena in health. The gradient in health is apparent in objective and subjective measures, across virtually all countries, and is evident at individual and population levels. There is no longer much debate over the relationship between SES and health. However, exact causal pathways remain elusive. Advocating for strong policy to reduce or eliminate the SES-health gradient necessitates understanding the causal pathways, from intervention to outcome. While economists are not convinced that there is a clear enough understanding of the causal pathways of the SEShealth gradient, they have produced a substantial body of work from which to move forward. The article briefly discusses the theoretical underpinnings used by economists as a basis for the study of the causal pathways for the health gradient. That presentation is followed by a concise overview of some of the evidence that economists have produced. The paper concludes with a discussion of how current economic evidence may be used to help policymakers advocate for interventions to limit the SES gradient in noncommunicable diseases.

Nutrition Care after Discharge from Hospital: An Exploratory Analysis from the More-2-Eat Study.

Many patients leave hospital in poor nutritional states, yet little is known about the post-discharge nutrition care in which patients are engaged. This study describes the nutrition-care activities 30-days post-discharge reported by patients and what covariates are associated with these activities. Quasi-randomly selected patients recruited from 5 medical units across Canada (n = 513) consented to 30-days post-discharge data collection with 48.5% (n = 249) completing the telephone interview. Use of nutrition care post-discharge was reported and bivariate analysis completed with relevant covariates for the two most frequently reported activities, following recommendations post-discharge or use of oral nutritional supplements (ONS). A total of 42% (n = 110) received nutrition recommendations at hospital discharge, with 65% (n = 71/110) of these participants following those recommendations; 26.5% (n = 66) were taking ONS after hospitalization. Participants who followed recommendations were more likely to report following a special diet (p = 0.002), different from before their hospitalization (p = 0.008), compared to those who received recommendations, but reported not following them. Patients taking ONS were more likely to be at nutrition risk (p < 0.0001), malnourished (p = 0.0006), taking ONS in hospital (p = 0.01), had a lower HGS (p = 0.0013; males only), and less likely to believe they were eating enough to meet their body's needs (p = 0.005). This analysis provides new insights on nutrition-care post-discharge.

Comparing Hospital Staff Nutrition Knowledge, Attitudes, and Practices Before and 1 Year After Improving Nutrition Care: Results From the More-2-Eat Implementation Project.

BACKGROUND: Staff play key roles in the prevention, detection, and treatment of hospital malnutrition. Understanding staff knowledge, attitudes, and practices (KAP) is important for developing and evaluating change management strategies. METHODS: The More-2-Eat project improved nutrition care in 5 Canadian hospitals by implementing the Integrated Nutrition Pathway for Acute Care (INPAC). To understand staff views before (T1) and after 1 year of implementation (T2), a reliable KAP questionnaire, based on INPAC, was administered. T2 included questions about involvement in implementation. The mean difference between T2 and T1 responses was calculated, and t tests were used for comparisons. RESULTS: The questionnaire was completed at T1 (n = 189) and T2 (n = 147) (unpaired); 57 staff completed both questionnaires (paired). A significant increase in total score was seen in unpaired results at T2 (from 93.6/128 [range, 51-124] to 99.5/128 [range, 54-119]; t = 5.97, P < .0001), with an increase in knowledge/attitudes (KA) (t = 2.4, P = .016) and practice (t = 3.57, P < .0001) components. There were no statistically significant changes in paired responses. Seventy percent (n = 102/147) noticed positive changes in practices, 12% (n = 18) noticed positive/negative changes, 1% (n = 1) noticed negative change, and 17% (n = 25) noticed no change. Fifty-nine percent (n = 86) felt involved in the change, and these staff had higher KA and KAP scores than those who did not feel involved. CONCLUSION: Staff involvement is important in the implementation process for improving nutrition care.

Costs of hospital malnutrition.

BACKGROUND & AIMS: Hospital malnutrition has been established as a critical, prevalent, and costly problem in many countries. Many cost studies are limited due to study population or cost data used. The aims of this study were to determine: the relationship between malnutrition and hospital costs; the influence of confounders on, and the drivers (medical or surgical patients or degree of malnutrition) of the relationship; and whether hospital reported cost data provide similar information to administrative data. To our knowledge, the last two goals have not been studied elsewhere. METHODS: Univariate and multivariate analyses were performed on data from the Canadian Malnutrition Task Force prospective cohort study combined with administrative data from the Canadian Institute for Health Information. Subjective Global Assessment was used to assess the relationship between nutritional status and length of stay and hospital costs, controlling for health and demographic characteristics, for 956 patients admitted to medical and surgical wards in 18 hospitals across Canada. RESULTS: After controlling for patient and hospital characteristics, moderately malnourished patients' (34% of surveyed patients) hospital stays were 18% (p = 0.014) longer on average than well-nourished patients. Medical stays increased by 23% (p = 0.014), and surgical stays by 32% (p = 0.015). Costs were, on average, between 31% and 34% (p-values < 0.05) higher than for well-nourished patients with similar characteristics. Severely malnourished patients (11% of surveyed patients) stayed 34% (p = 0.000) longer and had 38% (p = 0.003) higher total costs than well-nourished patients. They stayed 53% (p = 0.001) longer in medical beds and had 55% (p = 0.003) higher medical costs, on average. Trends were similar no matter the type of costing data used. CONCLUSIONS: Over 40% of patients were found to be malnourished (1/3 moderately and 1/10 severely). Malnourished patients had longer hospital stays and as a result cost more than well-nourished patients.

The relationship between work hours and utilization of general practitioners in four Canadian provinces.

OBJECTIVE: To assess whether long work hours act as a barrier to accessing general practitioner (GP) services. DATA SOURCES: Secondary data from the 1996/1997 National Population Health Survey (NPHS) and administrative health services utilization data from four Canadian provinces. STUDY DESIGN: This study was cross-sectional, however, employment variables and GP utilization were reflective of the 12-month period preceding the NPHS interview date. Negative binomial regression was used to model the relationship between the number of GP visits in a 1-year period and employment-related variables while adjusting for other determinants of GP utilization including education, income, and health status. DATA EXTRACTION METHODS: NPHS and administrative data were linked to create an analysis file. PRINCIPAL FINDINGS: Subjects with long, standard work hours (>45 hours/week, with most hours during the day) had significantly lower GP utilization rates compared with full-time workers. White-collar workers with long work hours visited a GP significantly less often than white-collar workers with regular hours. CONCLUSIONS: Long work hours may act as a nonfinancial barrier to accessing GP services independent of health status.

Social assistance, lone parents and health: what do we know, where do we go?

BACKGROUND: A mounting body of evidence indicates that lone mothers and their children are at higher risk of a variety of health problems. The dynamics of the relationship between social assistance, poverty and health are not well understood, and the study of this population presents substantial challenges. The purpose of this paper is to present an analysis of the state of research on lone parents, social assistance and health in an effort to make recommendations that will move the research forward. METHODS: Reviews of the relevant literature and social policies were conducted to identify (1) trends in social assistance policy and the extent of interprovincial variation in policy, and (2) research gaps. A series of interviews were conducted with key informants in government, non-governmental organizations and academia to gather information regarding research obstacles, opportunities and priorities. Finally, a consensus-building workshop was held to form research recommendations. RESULTS: A substantial degree of variation exists among provinces and territories with regard to social assistance policies. The nature of the variation, however, is complex and does not fall into tightly defined categories. This variation creates the possibility for "natural experiments" to examine the health implications of policies and practices. The pace of policy change, however, creates problems with respect to evaluation of specific policy initiatives. Interviewees and workshop participants recognized substantial impediments to research in this area, particularly regarding the availability of appropriate data. CONCLUSION: A research agenda, data development and dissemination activities were proposed to increase the research activity; these would be based upon multi-disciplinary, multi-sectoral collaborations using multiple methodologies. The creation of a multi-disciplinary, multi-sectoral national consortium in social assistance and health, reflecting the appropriate mix of urban, rural, anglophone, francophone and First Nations communities, is proposed.

Mutual influences on maternal depression and child adjustment problems.

Often undetected and poorly managed, maternal depression and child adjustment problems are common health problems and impose significant burden to society. Studies show evidence of mutual influences on maternal and child functioning, whereby depression in mothers increases risk of emotional and behavioral problems in children and vice versa. Biological mechanisms (genetics, in utero environment) mediate influences from mother to child, while psychosocial (attachment, child discipline, modeling, family functioning) and social capital (social resources, social support) mechanisms mediate transactional influences on maternal depression and child adjustment problems. Mutual family influences in the etiology and maintenance of psychological problems advance our understanding of pathways of risk and resilience and their implications for clinical interventions. This article explores the dynamic interplay of maternal and child distress and provides evidence for a biopsychosocial model of mediating factors with the aim of stimulating further research and contributing to more inclusive therapies for families.

Temporal relations in daily-reported maternal mood and disruptive child behavior.

Examined temporal relations between maternal mood and disruptive child behaviour using daily assessments of 30 mother-child dyads carried out over 8 consecutive weeks (623 pooled observations). Pooled time-series analyses showed synchronous fluctuation in child behaviour and maternal distress. Time-lagged models showed temporal relations between maternal and child outcomes that changed according to the type of maternal mood and child behaviour being reported. Controlling for cross-sectional relations, maternal anger and fatigue were related to previous child inattentive/impulsive/overactive behaviour (IO) and maternal confusion related to previous child oppositional/defiant behaviour (OD). However, maternal depression, low vigour, anger, and anxiety each predicted subsequent child IO and maternal confusion and anxiety each predicted subsequent child OD. Mutual influences on maternal and child functioning were interpreted in the context of interpersonal mechanisms that mediate psychological problems within families and their implications for treatment.

Social transfers and the health status of mothers in Norway and Canada.

The unconditional health status of lone mothers is worse than that of married mothers in Canada but not in Norway. Even controlling for demographic characteristics and health behaviours in Canada, the health status of lone mothers is worse. Only after we control for income does the differential in health status between married and lone mothers in Canada disappear. An important difference between the countries is that lone mothers are much less likely to be poor in Norway because they receive more generous social transfers. A simulation which involves 'giving Canadian mothers Norwegian transfers,' illustrates the possibility of significant gains in socioeconomic status and health of poor mothers in Canada.

Antecedent-consequence conditions in maternal mood and child adjustment: a four-year cross-lagged study.

Examined the mutual influence on maternal depressive symptoms and child adjustment problems and their antecedent-consequence conditions across 3 cycles of panel data collected over a 4-year period in the National Longitudinal Survey of Children and Youth (NLSCY). Results indicated stability in, and relations between, maternal and child outcomes. Cross-lagged panel correlations showed that maternal depressive symptoms tended to precede child aggression and hyperactivity but tended to follow child emotional problems. Temporal relations were interpreted in the context of mechanisms that transmit risk between mothers and children. Logistic regression analysis showed bidirectional risk between maternal mood and child adjustment after earlier symptoms were statistically controlled. These findings indicate that maternal depression increases the risk of adjustment problems in children, and vice versa, underscoring the intergenerational transmission of psychopathology.

Association of socio-economic factors with health risk behaviours among high school students in rural Nova Scotia.

OBJECTIVE: To determine the association of socio-economic (SES) factors with risk behaviours among adolescents. METHODS: A cross-sectional survey was carried out on students in four high schools in northern Nova Scotia, Canada. Associations between SES variables and substance use behaviours, having early intercourse and suicide attempt in the past year were examined using multivariate analysis (logit regression). Negative binomial regression was performed for associations of SES with a total risk score summing risk behaviours. RESULTS: Participants included 2,198 students (48% males; 52% females) ranging in age from 14 to 20 years. Almost 25% of youth smoked regularly, 19% of males smoked marijuana > or = 10 times monthly, more than 40% of males regularly drank excessively, and 10% of students > 14 years old had had intercourse before age 15. Smoking was the behaviour most often associated with lower SES in both genders. Mother's not being employed was protective against all substance use variables except driving after drinking. Living both with lone mother and in any family arrangement other than with both parents was associated with smoking, using marijuana, and early sex. Higher risk score was associated with living with a lone mother or other family arrangement. Lower risk score was associated with father having more than high school education and mother not working. INTERPRETATION: Lower socio-economic status is associated with adolescent risk behaviours. These findings point to the importance of these factors to risk-taking in youth, their relevance to social policy, and also their importance as factors to consider in targeted interventions.
