Differences in program implementation between nurses and paraprofessionals providing home visits during pregnancy and infancy: a randomized trial

Does supplementary prenatal nursing and home visitation reduce healthcare costs in the year after childbirth?

AIM

This paper reports the costs of a programme of supplementary prenatal care, including healthcare costs, in the year following childbirth.

BACKGROUND

Publicly funded healthcare systems have provided pregnant women with adequate medical care, but access to resources to address their non-medical needs is still an issue. To improve women's access to pregnancy-related resources, a community-based, prenatal programme involving consultations with a specialist nurse, or nurse plus a home visitor was evaluated.

METHOD

A sample of 284 women who had participated in a randomized controlled trial of the prenatal care programme participated in this partial economic analysis. Women had been randomized to one of three trial arms: (1) standard care, (2) standard care plus consultations with a specialist prenatal care nurse, or (3) standard care plus nurse consultations and a home visitor. For the economic study, each woman was asked about her and her baby's use of healthcare services in the 12 months after the baby's birth. Health service utilization was multiplied by the unit cost of each service and summed to arrive at the total cost of services used. The study was undertaken in 2004.

RESULTS

Supplementary prenatal care neither increased the use of health services nor resulted in savings in health spending. Compared with standard care, women in the two intervention groups made more use of family physicians and less use of paediatricians, but no significant differences in the overall costs of health care were noted.

CONCLUSION

While supplementary prenatal care had no impact on costs, some benefits occurred for those at greatest risk of not accessing services. However, it would be premature to draw widespread recommendations for policy from the results of a single study. Further investment in prenatal care should continue to be accompanied by rigorous evaluation of its costs and the value that women place on the service provided.

Addressing Mental Health and Stress in Medicaid-Insured Pregnant Women Using a Nurse-Community Health Worker Home Visiting Team

OBJECTIVE

To describe the conceptual framework and program features of a nurse-community health worker (CHW) team home visiting intervention, the trial design to test the program, and the results of a comparative evaluation of prenatal program participation.

DESIGN

In the context of a community-based, randomized trial, we compared participation in a nurse-CHW team intervention with the standard community care that included a state Medicaid program (enhanced prenatal services) with nurse home visiting.

SAMPLE

Medicaid-eligible pregnant women (n=530), who maintained their pregnancies, had a live birth, retained custody of the child, completed more than an enrollment assessment, did not move out of the county, and were not lost to follow-up.

MEASUREMENTS

Provider reports of face-to-face prenatal contacts and demographic and psychosocial risk assessments obtained at study enrollment.

RESULTS

Significant differences in the number of women with prenatal program contact and the total amount of contact were found, favoring the nurse-CHW team approach. More women with risk characteristics were reached in the nurse-CHW team group, with the exception of women with alcohol and drug use risks.

CONCLUSIONS

A nurse-CHW team approach demonstrated advantage in reaching women who had barriers to participation and delivering more intensive services.

Programs for parents of infants and toddlers: recent evidence from randomized trials

Programs for parents of young children hold considerable promise for improving children's life-course trajectories and for reducing health and development problems and associated costs to government and society. To date, this promise has not been achieved. Fulfilling the potential of parenting interventions will require substantial improvements in current practice for developing and testing such programs. Intervention development will be improved if clinicians and investigators ground parenting interventions in theory and epidemiology; and carefully pilot them to ascertain program feasibility, participant engagement, and behavioral change prior to testing them in randomized trials. Studies of parenting interventions will be improved if they adhere to the highest standards for randomization; if they examine objectively measured outcomes with clear public health relevance; and if they minimize selection factors known to compromise the analysis of data. Policy and practice recommendations for parenting interventions will be improved if they are based upon replicated randomized controlled trials, if the interventions are tested with different populations living in different contexts, and if they are examined in dissemination studies before public investments are made in such programs. Procedures need to be developed to ensure that the essential elements of evidence-based parenting programs can be implemented reliably in a variety of practice settings so that they will produce their intended effects. To date, few programs have met these high programmatic and evidentiary standards, with the result that many large-scale policy initiatives for at-risk parents have failed. Evidence is accumulating, however, that some programs delivered by professionals, especially nurse home visiting programs for pregnant women and parents of young children, produce replicable effects on children's health and development, and that these programs can be reliably reproduced with different populations living in a variety of community settings.

Community empowerment: a partnership approach to public health program implementation

Public policy implementation models reflect who makes decisions, how success is defined, and whether learning is built into decision making. The extant implementation models capture many important features of public policy implementation, including the desire of large public bureaucracies to impose order and rationality on implementation structures that include many public and private organizations. Analysis of the three-decades-long process of implementation of the Special Supplemental Nutrition Program for Women, Infants, and Children suggests that a new public policy implementation model is needed. The new model builds on the iterative learning cycles and shared decision making of community participatory research and better addresses the transactional relationship between program targets and providers than do current implementation models.

Formative evaluation of home visitors' role in addressing poor mental health, domestic violence, and substance abuse among low-income pregnant and parenting women

OBJECTIVES

This research assessed home visitor effectiveness in communicating about and responding to poor mental health, domestic violence, and substance abuse among pregnant and parenting women home visited as part of a comprehensive family support strategy in seven urban communities.

METHODS

Cross-sectional studies were conducted with mothers (n = 189) actively engaged in home visitation programs and home visitors (n = 45). Maternal interviews assessed need for and receipt of mental health, domestic violence, and substance abuse services, and home visitor discussion of these risk areas. Home visitor surveys assessed perceived adequacy of training and personal effectiveness in addressing these risk areas.

RESULTS

Over half of mothers needed mental health, domestic violence, or substance abuse services; however, only 27% of mothers in need of service received services. Most mothers reported having communicated with their home visitor about the three risk areas, but there were no differences in communication frequency based on whether services were needed. Most home visitors perceived themselves as effective in communicating about and responding to these risk factors but rated the training they had received in these areas as less than adequate.

CONCLUSIONS

Home visitors could benefit from more intensive training in the formal assessment of risks and the protocols for communication about those risks with their clients. Home visitors could also receive support from and work in collaboration with professionals in addressing client risks. Further research on home visit content is needed to determine which strategies facilitate home visitors' ability to effectively communicate about and address client risks.

Translating a research intervention into community practice: the nurse family partnership

Public policy initiatives have begun to recommend that interventions have strong evidence of effectiveness before there is expenditure of restrained public funds. The Nurse Family Partnership (NFP), a home visiting program for low-income parents expecting their first child, has been identified as a preventive intervention program that meets high evidentiary standards based on results from three randomized trials. Strategies used to promote successful translation of the research intervention into clinical practice, findings from the evaluation of the replication of the NFP in 22 states, and challenges experienced in moving a research program to practice are discussed. EDITORS' STRATEGIC IMPLICATIONS: Policymakers, community public health officials, and researchers planning to disseminate their prevention programs will find many lessons in this example of bringing a model program (i.e., a prevention strategy that works) up to scale. Although results at replication sites are somewhat weaker than at model sites, the consistent positive outcomes are a testimony to the strength of the NFP model and the fidelity of its implementation across sites.

Home visits during pregnancy and after birth for women with an alcohol or drug problem

BACKGROUND

One potential method of improving outcome for pregnant or postpartum women with a drug or alcohol problem is with home visits.

OBJECTIVES

To determine the effects of home visits during pregnancy and/or after birth for pregnant women with a drug or alcohol problem.

SEARCH STRATEGY

We searched the Cochrane Pregnancy and Childbirth Trials Register (30 April 2004), CENTRAL (The Cochrane Library, Issue 2, 2004), MEDLINE (1966 to April 2004), EMBASE (1980 to week 16, 2004), CINAHL (1982 to April 2004), PsycINFO (1974 to April 2004), citations from previous reviews and trials, and contacted expert informants.

SELECTION CRITERIA

Studies using random or quasi-random allocation of pregnant or postpartum women with a drug or alcohol problem to home visits. Trials enrolling high-risk women of whom more than 50% were reported to use drugs or alcohol were also eligible.

DATA COLLECTION AND ANALYSIS

Assessments of trials were performed independently by all review authors. Statistical analyses were performed using fixed and random-effects models where appropriate.

MAIN RESULTS

Six studies (709 women) compared home visits after birth with no home visits. None provided a significant antenatal component of home visits. The visitors included community health nurses, pediatric nurses, trained counsellors, paraprofessional advocates, midwives and lay African-American women. Most studies had methodological limitations, particularly large losses to follow up. There were no significant differences in continued illicit drug use (2 studies, 248 women; relative risk (RR) 0.95, 95% confidence interval (CI) 0.75 to 1.20), continued alcohol use (RR 1.08, 95% CI 0.83 to 1.41) failure to enrol in a drug treatment program (2 studies, 211 women; RR 0.45 95% CI 0.10 to 1.94). There was no significant difference in the Bayley MDI (3 studies, 199 infants; weighted mean difference 2.89, 95% CI -1.17 to 6.95) or Psychomotor Index (WMD 3.14, 95% CI -0.03 to 6.32). Other outcomes reported by one study only included breastfeeding at six months (RR 1.00, 95% CI 0.81 to 1.23), incomplete six-month infant vaccination schedule (RR 1.07, 95% CI 0.58 to 1.96), non-accidental injury and non-voluntary foster care (RR 0.16, 95% CI 0.02 to 1.23), failure to use postpartum contraception (RR 0.41, 95% CI 0.20 to 0.82), child behavioural problems (RR 0.46, 95% CI 0.21 to 1.01), and involvement with child protective services (RR 0.38, 95% CI 0.20 to 0.74).

AUTHORS' CONCLUSIONS

There is insufficient evidence to recommend the routine use of home visits for women with a drug or alcohol problem. Further large, high-quality trials are needed, and women's views on home visiting need to be assessed.

Standards of Evidence: Criteria for Efficacy, Effectiveness and Dissemination

Ever increasing demands for accountability, together with the proliferation of lists of evidence-based prevention programs and policies, led the Society for Prevention Research to charge a committee with establishing standards for identifying effective prevention programs and policies. Recognizing that interventions that are effective and ready for dissemination are a subset of effective programs and policies, and that effective programs and policies are a subset of efficacious interventions, SPR's Standards Committee developed overlapping sets of standards. We designed these Standards to assist practitioners, policy makers, and administrators to determine which interventions are efficacious, which are effective, and which are ready for dissemination. Under these Standards, an efficacious intervention will have been tested in at least two rigorous trials that (1) involved defined samples from defined populations, (2) used psychometrically sound measures and data collection procedures; (3) analyzed their data with rigorous statistical approaches; (4) showed consistent positive effects (without serious iatrogenic effects); and (5) reported at least one significant long-term follow-up. An effective intervention under these Standards will not only meet all standards for efficacious interventions, but also will have (1) manuals, appropriate training, and technical support available to allow third parties to adopt and implement the intervention; (2) been evaluated under real-world conditions in studies that included sound measurement of the level of implementation and engagement of the target audience (in both the intervention and control conditions); (3) indicated the practical importance of intervention outcome effects; and (4) clearly demonstrated to whom intervention findings can be generalized. An intervention recognized as ready for broad dissemination under these Standards will not only meet all standards for efficacious and effective interventions, but will also provide (1) evidence of the ability to "go to scale"; (2) clear cost information; and (3) monitoring and evaluation tools so that adopting agencies can monitor or evaluate how well the intervention works in their settings. Finally, the Standards Committee identified possible standards desirable for current and future areas of prevention science as the field develops. If successful, these Standards will inform efforts in the field to find prevention programs and policies that are of proven efficacy, effectiveness, or readiness for adoption and will guide prevention scientists as they seek to discover, research, and bring to the field new prevention programs and policies.

Does participation in a nurse visitation programme reduce the frequency of adverse perinatal outcomes in first-time mothers?

Children First (C1), a nurse home visitation programme for first-time mothers, was implemented statewide in Oklahoma in mid-1997. The objective of this study was to compare the risks of low (< 2500 g) and very low birthweight (< 1500 g), preterm (< 37 weeks) and very preterm (< 30 weeks) deliveries and infant mortality between mothers participating and not participating in C1. All 239,466 Oklahoma birth certificates were reviewed. The C1 and birth certificate databases were matched to identify C1 participants. Mother's age at delivery, education level, race, marital status, prior pregnancy loss or pregnancy risk factors, birthweight and gestational age at delivery were measured from the birth certificates. Death certificates were matched to the birth certificates to identify infant deaths. A Bayesian multivariable logistic regression was used to analyse the data. Among single mothers without pregnancy risk factors, the risks of all study outcomes were lower for participants in C1: adjusted odds ratio (aOR) 0.89, [95% Bayesian Credible Interval (BCI) 0.79, 1.00] for preterm delivery; aOR 0.71, [95% BCI 0.50, 0.98] for very preterm delivery; aOR 0.86, [95% BCI 0.75, 0.98] for low birthweight; aOR 0.77, [95% BCI 0.56, 1.02] for very low birthweight and aOR 0.36, [95% BCI 0.17, 0.63] for infant mortality. These risk reductions were not observed among married mothers. In both single and married mothers, the presence of pregnancy risk factors reduced the impact of C1 on lowering the risk of low birthweight and preterm deliveries. The C1 programme targets young, pregnant women of low socio-economic level. We found that among single mothers, the risks of perinatal adverse outcomes are reduced or similar to those found in non-participating mothers. A reduced effect of C1 in the presence of pregnancy risk factors may be because mothers with pregnancy risk factors who did not participate in C1 received better prenatal care, or that C1 interventions do not impact these particular factors. C1 shows promise in reducing infant mortality in single mothers. Lower incidence of preterm and very preterm deliveries is especially interesting and future analyses should focus on isolating programme components specifically associated with influencing these outcomes.

Lay health workers in primary and community health care

BACKGROUND

Lay health workers (LHWs) are widely used to provide care for a broad range of health issues. However, little is known about the effectiveness of LHW interventions.

OBJECTIVES

To assess the effects of LHW interventions in primary and community health care on health care behaviours, patients' health and wellbeing, and patients' satisfaction with care.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care and Consumers and Communication specialised registers (to August 2001); the Cochrane Central Register of Controlled Trials (to August 2001); MEDLINE (1966- August 2001); EMBASE (1966-August 2001); Science Citations (to August 2001); CINAHL (1966-June 2001); Healthstar (1975-2000); AMED (1966-August 2001); the Leeds Health Education Effectiveness Database and the reference lists of articles.

SELECTION CRITERIA

Randomised controlled trials of any intervention delivered by LHWs (paid or voluntary) in primary or community health care and intended to promote health, manage illness or provide support to patients. A 'lay health worker' was defined as any health worker carrying out functions related to health care delivery; trained in some way in the context of the intervention; and having no formal professional or paraprofessional certificated or degreed tertiary education. There were no restrictions on the types of consumers.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data onto a standard form and assessed study quality. Studies that compared broadly similar types of interventions were grouped together. Where feasible, the results of included studies were combined and an estimate of effect obtained.

MAIN RESULTS

Forty three studies met the inclusion criteria, involving more than 210,110 consumers. These showed considerable diversity in the targeted health issue and the aims, content and outcomes of interventions. Most were conducted in high income countries (n=35), but nearly half of these focused on low income and minority populations (n=15). Study diversity limited meta-analysis to outcomes for five subgroups (n=15 studies) (LHW interventions to promote the uptake of breast cancer screening, immunisation and breastfeeding promotion [before two weeks and between two weeks and six months post partum] and to improve diagnosis and treatment for selected infectious diseases). Promising benefits in comparison with usual care were shown for LHW interventions to promote immunisation uptake in children and adults (RR=1.30 [95% CI 1.14, 1.48] p=0.0001) and LHW interventions to improve outcomes for selected infectious diseases (RR=0.74 [95% CI 0.58, 0.93) p=0.01). LHWs also appear promising for breastfeeding promotion. They appear to have a small effect in promoting breast cancer screening uptake when compared with usual care. For the remaining subgroups (n=29 studies), the outcomes were too diverse to allow statistical pooling. We can therefore draw no general conclusions on the effectiveness of these subgroups of interventions.

AUTHORS' CONCLUSIONS

LHWs show promising benefits in promoting immunisation uptake and improving outcomes for acute respiratory infections and malaria, when compared to usual care. For other health issues, evidence is insufficient to justify recommendations for policy and practice. There is also insufficient evidence to assess which LHW training or intervention strategies are likely to be most effective. Further research is needed in these areas.

Effects of home visits by paraprofessionals and by nurses: age 4 follow-up results of a randomized trial

OBJECTIVE

To examine the effects of prenatal and infancy home visiting by paraprofessionals and by nurses from child age 2 through age 4 years.

METHODS

We conducted, in public and private care settings in Denver, Colorado, a randomized, controlled trial with 3 arms, ie, control, paraprofessional visits, and nurse visits. Home visits were provided from pregnancy through child age 2 years. We invited 1178 consecutive, low-income, pregnant women with no previous live births to participate, and we randomized 735; 85% were unmarried, 47% Mexican American, 35% white non-Mexican American, 15% black, and 3% American Indian/Asian. Outcomes consisted of maternal reports of subsequent pregnancies, participation in education and work, use of welfare, marriage, cohabitation, experience of domestic violence, mental health, substance use, and sense of mastery; observations of mother-child interaction and the home environment; tests of children's language and executive functioning; and mothers' reports of children's externalizing behavior problems.

RESULTS

Two years after the program ended, women who were visited by paraprofessionals, compared with control subjects, were less likely to be married (32.2% vs 44.0%) and to live with the biological father of the child (32.7% vs 43.1%) but worked more (15.13 months vs 13.38 months) and reported a greater sense of mastery and better mental health (standardized scores [mean = 100, SD = 10] of 101.25 vs 99.31 and 101.21 vs 99.16, respectively). Paraprofessional-visited women had fewer subsequent miscarriages (6.6% vs 12.3%) and low birth weight newborns (2.8% vs 7.7%). Mothers and children who were visited by paraprofessionals, compared with control subjects, displayed greater sensitivity and responsiveness toward one another (standardized score [mean = 100, SD = 10] of 100.92 vs 98.66) and, in cases in which the mothers had low levels of psychologic resources at registration, had home environments that were more supportive of children's early learning (score of 24.63 vs 23.35). Nurse-visited women reported greater intervals between the births of their first and second children (24.51 months vs 20.39 months) and less domestic violence (6.9% vs 13.6%) and enrolled their children less frequently in preschool, Head Start, or licensed day care than did control subjects. Nurse-visited children whose mothers had low levels of psychologic resources at registration, compared with control group counterparts, demonstrated home environments that were more supportive of children's early learning (score of 24.61 vs 23.35), more advanced language (score of 91.39 vs 86.73), superior executive functioning (score of 100.16 vs 95.48), and better behavioral adaptation during testing (score of 100.41 vs 96.66). There were no statistically significant effects of either nurse or paraprofessional visits on the number of subsequent pregnancies, women's educational achievement, use of substances, use of welfare, or children's externalizing behavior problems.

CONCLUSIONS

Paraprofessional-visited mothers began to experience benefits from the program 2 years after the program ended at child age 2 years, but their first-born children were not statistically distinguishable from their control group counterparts. Nurse-visited mothers and children continued to benefit from the program 2 years after it ended. The impact of the nurse-delivered program on children was concentrated on children born to mothers with low levels of psychologic resources.

Randomized trial of a statewide home visiting program to prevent child abuse: impact in reducing parental risk factors

OBJECTIVES

To assess the impact of a home visiting program in reducing malleable parental risk factors for child abuse in families of newborns identified, through population-based screening, as at-risk of child abuse.

METHODS

This randomized trial focused on Healthy Start Program (HSP) sites operated by three community-based organizations on Oahu, HI, USA. From 11/94 to 12/95, 643 families were enrolled and randomly assigned to intervention and control groups. Mothers in both groups were interviewed annually for 3 years (88% follow-up each year) to measure mental health, substance use, and partner violence. HSP records were reviewed to measure home visiting services provided. Home visitors were surveyed annually to measure their perceived competence.

RESULTS

Malleable parental risks for child abuse were common at baseline. There was no significant overall program effect on any risk or on at-risk mothers' desire for and use of community services to address risks. There was a significant reduction in one measure of poor mental health at one agency and a significant reduction in maternal problem alcohol use and repeated incidents of physical partner violence for families receiving > or =75% of visits called for in the model. Home visitors often failed to recognize parental risks and seldom linked families with community resources. HSP training programs were under-developed in preparing staff to address risks and to link families with community resources.

CONCLUSIONS

Overall, the home visiting program did not reduce major risk factors for child abuse that made families eligible for service. Research is needed to develop and test strategies to improve home visiting effectiveness in reducing parental risks for child abuse.

The impact of parental problem drug use on children: what is the problem and what can be done to help?

AIM

To review the literature on the impact of parental problem drug use on children, and indicate the efficacy of key evaluated interventions to reduce the impact of parental drug use on children.

METHODS

Comprehensive narrative review of English language published research and intervention spanning the last three decades identified through searching library databases and citation.

FINDINGS

Problem drug use can impede parenting and the provision of a nurturing environment. Although small-scale, localized and resource-intensive these key evaluated interventions show cautious optimism that problem drug-using parents can reduce drug use and achieve better family management. Children have rarely been directly the focus of intervention.

CONCLUSIONS

Wider application and more rigorous evaluation of interventions in this area are needed. Given the scale of the problem it is important to establish how statutory services can apply the lessons of these more localized interventions.

Paraprofessional Support for Pregnant & Parenting Women

PURPOSE

To review evidence regarding the role of paraprofessional support in improving maternal and infant outcomes in pregnant and parenting women. Although support provided by significant others (social support), by professionals, and by paraprofessionals are frequently considered together in literature reviews, this is inappropriate because the components of the support in each case differ.

DATA SOURCES

Data were limited to published studies. Searches of computerized databases (CINAHL, Medline, PsychLit, Social sciences abstracts, Social sciences citation, and Social work abstracts), hand searches of journals, and backward searches from reference lists of studies were conducted. Nursing, medicine, psychology, public health, sociology, and social work literatures were searched.

STUDY SELECTION

The studies included had statistically significant outcomes of paraprofessional support to pregnant and parenting women. Studies were published in 1985 or later, were conducted in the United States or Canada, and included maternal and/or infant outcomes.

DATA EXTRACTION

Data were extracted from each study concerning the theoretical framework, design, sample, measuring instruments, interventions, and outcomes.

CONCLUSIONS

Programs providing paraprofessional support to childbearing women are clearly providing an important service, but empirical evidence is not adequate to determine which specific paraprofessional program works for a specific population of women to achieve the best long-term outcomes for both women and children. Although proponents of paraprofessional support programs for pregnant and parenting women have reported some successes, more data are needed. Researchers should continue to conduct well-designed and controlled studies to compare outcomes from the three types of support. Nurses in practice should build on services provided by paraprofessionals in order to meet women's need for support and to achieve desired outcomes.

Lay Home Visiting May Improve Pregnancy Outcomes

Home visiting may be a promising strategy to improve pregnancy outcomes, and home visiting by lay workers may be more accepted by pregnant women. Lay workers may impact on social and environmental risk factors as well as on health care utilization. As with any primary prevention strategy, these programs may be more successful if implemented with responsibility shared between the health care system and the community. This article reviews the state of the science related to lay home visiting during pregnancy in the United States. Using a variety of search terms, an exhaustive review of the literature was conducted using several large electronic databases. Studies of lay home visiting during pregnancy have documented mixed results. Many weaknesses exist in the studies available, including use of descriptive or quasi-experimental designs in most of the studies, absence of a clearly specified set of interventions, and lack of cost analysis. Gaps in our knowledge of the impact of lay home visitors on pregnancy outcomes persist.

Does public health nurse home visitation make a difference in the health outcomes of pregnant clients and their offspring?

Public health nurses (PHNs) at Lincoln-Lancaster County Health Department have used the Care Pathway tool to track client progress. Conceptually similar to critical pathways used in hospital settings, the Care Pathway is used by the PHN to document milestones of progress by trimester of pregnancy. Data for this research was gathered from chart review of 55 prenatal clients. Study results demonstrate that subjects who had from five to nine home visits by a PHN during pregnancy showed a higher average hemoglobin for the mothers and a higher average birthweight for the babies than those visited four or fewer times. None of the low birthweight babies was born to mothers in the "more visits" category. Furthermore, more breastfeeding was recorded for those who had received more PHN visits. This documentation enabled us to describe better the referent population and to begin to estimate the effect of PHN home visitation on the health outcomes of clients. In essence, we addressed the questions: (1) "Does PHN home visitation make a difference in health outcomes of clients and their families?" and (2) "If so, how can effects be measured?"

Multi-level determinants of retention in a home-visiting child abuse prevention program

OBJECTIVE

This exploratory study investigated how attributes from multiple domains influence retention in a voluntary home-visiting child abuse prevention program.

METHOD

A sample of 1093 "at-risk" families participated in a home-visiting child abuse prevention program. A total of 71 Family Support Workers (FSWs) provided home visitation services in 12 different communities. Hierarchical general linear modeling (HGLM) was used to examine the community, home visitor, and maternal attributes that predicted retention in the program beyond 1 year.

RESULTS

Multi-level analyses (HGLM) revealed significant community, home visitor, and maternal level effects. Families were less likely to remain in a home-visiting child abuse prevention program for at least 1 year if they lived in an area with high community violence. Families were more likely to remain when the home visitor received more hours of direct supervision. Older mothers were more likely to remain for at least 1 year than were younger mothers. Hispanic mothers were more likely to remain than were White non-Hispanic mothers.

CONCLUSIONS

These findings demonstrate the utility of looking across multiple levels of influence when examining retention in home-visiting child abuse prevention programs. To increase retention rates home visitors will need to be adaptable to fit the needs of families in violent communities. Supervisors can influence retention rates by providing more hours of direct supervision. Other strategies that may contribute to program retention include meeting the scheduling needs of younger mothers and involving the families of younger mothers more effectively.

Postnatal home visits in teenage mothers: a randomised controlled trial

BACKGROUND

Teenage pregnancies are associated with negative socioeconomic effects. Our aim was to ascertain whether a postnatal home-visiting service for teenage mothers younger than age 18 years could reduce the frequency of adverse neonatal outcomes and improve knowledge of contraception, breastfeeding, and infant vaccination schedules in this parent group.

METHODS

We enrolled 139 adolescents, attending a teenage pregnancy clinic, in a randomised controlled trial. After completing an antenatal questionnaire designed to assess their knowledge of contraception, infant vaccination, and breastfeeding, we assigned participants to either receive five structured postnatal home visits by nurse-midwives (n=65) or not (n=71). Assessment interviews were done 6 months postpartum. Our primary endpoint was unadjusted difference in knowledge between groups, and incidence of predefined adverse neonatal outcomes. Analysis was by intention to treat.

FINDINGS

Three women withdrew before randomisation because of late fetal loss, 11 mothers withdrew because of adverse neonatal outcomes (adverse neonatal outcome was a primary endpoint, but resulted in withdrawal from the study for knowledge outcomes), and one left voluntarily. Follow-up data were, therefore, available for 124 teenagers. Postnatal home visits were associated with a reduction in adverse neonatal outcomes (intervention: 2; control: 9; relative risk 0.24, 95% CI 0.05-1.08), and a significant increase in contraception knowledge (mean difference 0.92, 95% CI 0.32-1.52). However, there was no significant increase in knowledge with respect to breastfeeding or infant vaccination schedules associated with the home visits.

INTERPRETATION

Postnatal home-visiting services by nurse-midwives reduce adverse neonatal events and improve contraception outcomes, but do not affect breastfeeding or infant vaccination knowledge or compliance.

Personal attributes and job competencies needed by EFNEP paraprofessionals as perceived by EFNEP professionals

OBJECTIVE

To determine the personal attributes and job competencies that are necessary for the job success of Expanded Food and Nutrition Education Program (EFNEP) paraprofessionals as perceived by EFNEP professionals.

DESIGN

A qualitative descriptive design and a 3-round modified Delphi methodology was used.

PARTICIPANTS

A convenience sample of 14 state and 20 county EFNEP professionals participated in all 3 Delphi rounds. The response rates for state and county professionals for all 3 Delphi rounds were 70% and 91%, respectively.

VARIABLES MEASURED

Personal attributes and job competencies were generated and the level of importance was determined.

ANALYSIS

An independent t test was employed to determine differences between importance scores by professional position.

RESULTS

Thirty-seven personal attributes, 18 job competencies prior to hire, and 43 job competencies after training were generated and the majority were very important to important. County EFNEP professionals tended to score personal attributes and job competencies as more important than state EFNEP professionals.

IMPLICATIONS

These personal attributes and job competencies prior to hire can guide hiring decisions and initial training content. The job competencies after training can shape content for inservice training.

Home visiting by paraprofessionals and by nurses: a randomized, controlled trial

OBJECTIVE

To examine the effectiveness of home visiting by paraprofessionals and by nurses as separate means of improving maternal and child health when both types of visitors are trained in a program model that has demonstrated effectiveness when delivered by nurses.

METHODS

A randomized, controlled trial was conducted in public- and private-care settings in Denver, Colorado. One thousand one hundred seventy-eight consecutive pregnant women with no previous live births who were eligible for Medicaid or who had no private health insurance were invited to participate. Seven hundred thirty-five women were randomized to control, paraprofessional, or nurse conditions. Nurses completed an average of 6.5 home visits during pregnancy and 21 visits from birth to the children's second birthdays. Paraprofessionals completed an average of 6.3 home visits during pregnancy and 16 visits from birth to the children's second birthdays. The main outcomes consisted of changes in women's urine cotinine over the course of pregnancy; women's use of ancillary services during pregnancy; subsequent pregnancies and births, educational achievement, workforce participation, and use of welfare; mother-infant responsive interaction; families' home environments; infants' emotional vulnerability in response to fear stimuli and low emotional vitality in response to joy and anger stimuli; and children's language and mental development, temperament, and behavioral problems.

RESULTS

Paraprofessional-visited mother-child pairs in which the mother had low psychological resources interacted with one another more responsively than their control-group counterparts (99.45 vs 97.54 standard score points). There were no other statistically significant paraprofessional effects. In contrast to their control-group counterparts, nurse-visited smokers had greater reductions in cotinine levels from intake to the end of pregnancy (259.0 vs 12.32 ng/mL); by the study child's second birthday, women visited by nurses had fewer subsequent pregnancies (29% vs 41%) and births (12% vs 19%); they delayed subsequent pregnancies for longer intervals; and during the second year after the birth of their first child, they worked more than women in the control group (6.83 vs 5.65 months). Nurse-visited mother-child pairs interacted with one another more responsively than those in the control group (100.31 vs 98.99 standard score points). At 6 months of age, nurse-visited infants, in contrast to their control-group counterparts, were less likely to exhibit emotional vulnerability in response to fear stimuli (16% vs 25%) and nurse-visited infants born to women with low psychological resources were less likely to exhibit low emotional vitality in response to joy and anger stimuli (24% vs 40% and 13% vs 33%). At 21 months, nurse-visited children born to women with low psychological resources were less likely to exhibit language delays (7% vs 18%); and at 24 months, they exhibited superior mental development (90.18 vs 86.20 Mental Development Index scores) than their control-group counterparts. There were no statistically significant program effects for the nurses on women's use of ancillary prenatal services, educational achievement, use of welfare, or their children's temperament or behavior problems. For most outcomes on which either visitor produced significant effects, the paraprofessionals typically had effects that were about half the size of those produced by nurses.

CONCLUSIONS

When trained in a model program of prenatal and infancy home visiting, paraprofessionals produced small effects that rarely achieved statistical or clinical significance; the absence of statistical significance for some outcomes is probably attributable to limited statistical power to detect small effects. Nurses produced significant effects on a wide range of maternal and child outcomes.

Can paraprofessional home visitation enhance early intervention service delivery?

A 1-year randomized trial compared intensive case management (ICM) versus basic case management (BCM) in facilitating early intervention (EI) service use among children in an urban health system. Of 159 participating families with delayed or at-risk preschool-aged children, 88 received ICM from paraprofessionals versus 71 families who received less comprehensive BCM from a nurse. In the ICM versus BCM group, a shorter interval to assessment (98 vs 140 d, p =.05) but similar assessment rate (86% vs 80%, p =.29) was observed. The ICM group had more services recommended per child (1.64 vs 1.16, p < .004) and initiated (1.20 vs 0.85, p < .04). There was no difference in median time to EI program initiation for ICM versus BCM (228 vs 200 d, p = .88) or initiation and visit compliance rate for EI services. Specific efforts to improve outcomes (e.g., decrease initiation time and increase use of EI services) are still needed.

Home visitation programs for at-risk young families. A systematic literature review

BACKGROUND

This systematic literature review is stimulated by the perceived need of investigator, practice and policy stakeholders for a complete but parsimonious summary of key elements of programs that use home visitation for at-risk young families as the major delivery method.

OBJECTIVES

To describe the program components, practices, outcomes, and reliability of the evaluation approaches.

METHODS

Computer and hand searches of literature were carried out. Reports of established programs, from the last five years, that describe home visitation services to at-risk families were included. A comprehensive data collection tool was used in the analysis of the findings.

FINDINGS

Improvements over the previous five years were seen in the following areas: use of early intervention model, inclusion of comparison groups and adequate sampling.

DISCUSSION

Challenges remain in development, targeting and reporting of home visitation practice, overall lack of impact, differential effects by program site, retention of participants and appropriate measurement.

Dropping out of maternal and child home visits

The purpose of this study was to examine the relationship between nurse and client characteristics and the reason for client termination from public health nursing maternal and child home visits. The results indicate that clients who dropped out of services received more contacts from the nurses, missed more appointments with the nurses, and were given advice from the nurses on more topics. They also differed from clients who continued with services until the nursing care plan goals were met in reference to marital status, mental illness, source of payment for services, and use of WIC and food stamps. Nurses whose clients were more likely to continue until goals were met were higher in conscientiousness, learned more from experience, and learned less from coworkers or learning on their own. They also worked more hours per week. These findings have implications for practice and research.

Adolescents at risk for mistreating their children. Part II: A home- and clinic-based prevention program

OBJECTIVE

To determine if adding an intensive home visitation component to a comprehensive adolescent-oriented maternity program prevents child abuse and neglect.

METHODS

We studied 171 participants in a comprehensive, adolescent-oriented maternity program who were deemed to be at high risk for child abuse and neglect. Half were randomly assigned to receive in-home parenting instruction. Major disruptions of primary care-giving by the adolescent mother were classified hierarchically as abuse, neglect, and abandonment.

RESULTS

Compliance with home visits varied in relation to the support the teenage mothers received from their families and the fathers of their babies (p < .0001). There were no significant treatment group differences in the pattern of health care utilization, the rate of postpartum school return, repeat pregnancies, or child abuse and neglect. The incidence of maltreatment rose in tandem with the predicted risk status of the mother. Ultimately, 19% of the children were removed from their mother's custody.

CONCLUSIONS

Prediction efforts were effective in identifying at-risk infants, but this intensive home- and clinic-based intervention did not alter the incidence of child maltreatment or maternal life course development. A parenting program that was more inclusive of the support network might be more popular with teenagers and therefore more effective. Our findings also emphasize the importance of including counseling specifically designed to prevent teenagers from abandoning their children.
