Support during pregnancy for women at increased risk of low birthweight babies.

Abstract: Background Studies consistently show a relationship between social disadvantage and low birthweight. Many countries have programs offering special assistance to women thought to be at risk for giving birth to a low birthweight infant. These programs may include advice and counseling (about nutrition, rest, stress management, alcohol, and recreational drug use), tangible assistance (e.g., transportation to clinic appointments, household help), and emotional support. The programs may be delivered by multidisciplinary teams of health professionals, specially trained lay workers, or combination of lay and professional workers. Objectives The primary objective was to assess effects of programs offering additional social support compared with routine care, for pregnant women believed at high risk for giving birth to babies that are either preterm or weigh less than 2500 gm, or both, at birth. Secondary objectives were to determine whether effectiveness of support was mediated by timing of onset (early versus later in pregnancy) or type of provider (healthcare professional or lay woman). Search methods We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (January 2010). Selection criteria Randomized trials of additional support during at-risk pregnancy by either a professional (social worker, midwife, or nurse) or specially trained lay person, compared to routine care. We defined additional support as some form of emotional support (e.g., counseling, reassurance, sympathetic listening) and information or advice or both, either in home visits or during clinic appointments, and could include tangible assistance (e.g., transportation to clinic appointments, assistance with care of other children at home). Data collection and analysis Two review authors evaluated methodological quality. We performed double data entry. Main results We included 17 trials (12,264 women). Programs offering additional social support for at-risk pregnant women were not associated with improvements in any perinatal outcomes, but there was a reduction in the likelihood of antenatal hospital admission (three trials; n = 737; RR 0.79, 95% CI 0.68 to 0.92) and caesarean birth (nine trials; n = 4522; RR 0.87, 95% CI 0.78 to 0.97). Authors' conclusions Pregnant women need the support of caring family members, friends, and health professionals. While programs which offer additional support during pregnancy are unlikely to prevent the pregnancy from resulting in a low birthweight or preterm baby, they may be helpful in reducing the likelihood of antenatal hospital admission and caesarean birth.

A multilevel model for measuring fit between a firm's competitive strategies and information systems capabilities

Abstract: To compete in a highly dynamic marketplace, firms must frequently adapt and align their competitive strategies and information systems. The dominant literature on the strategic fit of a firm's information systems focuses primarily on high-level measures of the strategic fit of a firm's overall IS portfolio and the impact of fit on business performance. This paper addresses the need for a more fine-grained approach for assessing the specific areas of misfit between a firm's competitive strategies and IS capabilities. We describe the design and evaluation of a multilevel strategic fit (MSF) measurement model that enables researchers and practitioners to measure the strategic fit of a firm's information systems at both an overall and a detailed level. The steps in the model include identifying the relevant IS capabilities according to the type of system; measuring the current level of support for each capability using a capabilities instrument; identifying the ideal level of support for each capability using an adaptation of Conant et al.'s (1990) instrument to assess strategic archetype; and comparing the ideal and realized level of support for each capability. Evidence from a multiple case study analysis indicates that the fine-grained assessment of strategic fit can strengthen the validity, utility, and ease of corroboration of the strategic fit measurement outputs. The paper also demonstrates how an iterative design science research approach, with its emphasis on evaluating the utility of prototype artifacts, is well suited to developing field-tested and theoretically grounded measurement models and instruments that are accessible to practitioners. This focus on practical utility in turn provides researchers with results that can be more readily corroborated, thus improving the quality and usefulness of the research findings.
