Development and pilot feasibility study of a health information technology tool to calculate mortality risk for patients with asymptomatic carotid stenosis: the Carotid Risk Assessment Tool (CARAT).

BACKGROUND: Patients with no history of stroke but with stenosis of the carotid arteries can reduce the risk of future stroke with surgery or stenting. At present, a physicians' ability to recommend optimal treatments based on an individual's risk profile requires estimating the likelihood that a patient will have a poor peri-operative outcomes and the likelihood that the patient will survive long enough to gain benefit from the procedure. We describe the development of the CArotid Risk Assessment Tool (CARAT) into a 2-year mortality risk calculator within the electronic medical record, integrating the tool into the clinical workflow, training the clinical team to use the tool, and assessing the feasibility and acceptability of the tool in one clinic setting. METHODS: We modified an existing clinical flowsheet with the local electronic medical record for the CARAT risk model. To understand how CARAT would fit into the existing clinical workflow, we observed the clinic and talked with the clinical staff to develop a process map for the existing clinical workflow. CARAT was completed by the clinic nurse for patients identified on the clinic schedule as having carotid narrowing. We analyzed post-implementation assessment in two ways: quantifying the proportion of eligible patients with whom CARAT was utilized, and surveying surgeons to understand the impact of CARAT on decision-making and clinical workflow. RESULTS: With minimum investment of institutional resources, we were able to produce a workable tool and pilot the tool in our clinic within a 6 month time period. Over 4 months, 287 patients were seen in the clinic with carotid narrowing, and clinic staff completed CARAT for 195 (68%). Per-surgeon completion rates ranged from 29 to 81%. Most patients (191 of 195, 98%) patients had a low 2-year calculated mortality risk. Most surgeons believed the risk assessment aligned with their expectations of patient predicted risk. CONCLUSIONS: We successfully integrated CARAT into the existing electronic medical record and have preliminary evidence that CARAT can be a valuable tool for evaluating mortality risk for patients with diseased carotid arteries. Accuracy of the risk calculations must be evaluated in larger, multi-center studies.

Delaying second births among adolescent mothers: a randomized, controlled trial of a home-based mentoring program.

CONTEXT: Rates of rapid second births among low-income black adolescent mothers range from 20% to 50%. Most efforts to prevent rapid second births have been unsuccessful. OBJECTIVES: There were 4 objectives: (1) to examine whether a home-based mentoring intervention was effective in preventing second births within 2 years of the adolescent mother's first delivery; (2) to examine whether greater intervention participation increased the likelihood of preventing a second birth; (3) to examine whether second births were better predicted from a risk practice perspective or a family formation perspective, based on information collected at delivery; and (4) to examine how risk practices or family formation over the first 2 years of parenthood were related to a second birth. DESIGN: We conducted a randomized, controlled trial of a home-based intervention curriculum, based on social cognitive theory, and focused on interpersonal negotiation skills, adolescent development, and parenting. The curriculum was delivered biweekly until the infant's first birthday by college-educated, black, single mothers who served as mentors, presenting themselves as "big sisters." The control group received usual care. Follow-up evaluations were conducted in the homes 6, 13, and 24 months after recruitment. METHODS: Participants were recruited from urban hospitals at delivery and were 181 first time, black adolescent mothers (< 18 years of age); 82% (149 of 181) completed the 24-month evaluation. RESULTS: Intent-to-treat analyses revealed that control mothers were more likely than intervention mothers to have a second infant. The complier average causal effect was used to account for variability in intervention participation. Having > or = 2 intervention visits increased the odds of not having a second infant more than threefold. Only 1 mother who completed > or = 6 visits had a second infant. At delivery of their first infant, mothers who had a second infant were slightly older (16.7 vs 16.2 years) and were more likely to have been arrested (30% vs 14%). There were no differences in baseline contraceptive use or other measures of risk or family formation. At 24 months, mothers who had a second infant reported high self-esteem, positive life events, and romantic involvement and residence with the first infant's father. At 24 months, there were no differences in marital rates (2%), risk practices, or contraceptive use between mothers who did and did not have a second infant. Mothers who did not have a second infant were marginally more likely to report no plans for contraception in their next sexual contact compared with mothers who had a second infant (22% vs 8%, respectively). CONCLUSIONS: A home-based intervention founded on a mentorship model and targeted toward adolescent development, including negotiation skills, was effective in preventing rapid repeat births among low-income, black adolescent mothers. The effectiveness of the intervention could be seen after only 2 visits and increased over time. There were no second births among mothers who attended > or = 8 sessions. There was no evidence that risk behavior or contraceptive use was related to rapid second births. There was some evidence that rapid second births among adolescent mothers were regarded as desirable and as part of a move toward increasing autonomy and family formation, thereby undermining intervention programs that focus on risk avoidance. Findings suggest the merits of a mentoring program for low-income, black adolescent mothers, based on a relatively brief (6-8 sessions) curriculum targeted toward adolescent development and interpersonal negotiation skills.

Parental perceptions of infant vulnerability in a preterm sample: prediction from maternal adaptation to parenthood during the neonatal period.

The present longitudinal study of African-American mothers of preterm infants tested the hypothesis that the quality of maternal adaptation to parenthood before infant discharge from the hospital is predictive of maternal perceptions of infant vulnerability later in the infant's first year. As hypothesized, perceptions of infant vulnerability at 3 to 4 months of infant corrected age were predicted by two theoretically relevant measures of maternal adaptation in the neonatal period: mothers' perceptions of their neonates as lethargic and unresponsive to mothers' bids and by low maternal self-efficacy beliefs about feeding the infant. Neonatally obtained maternal self-inefficacy beliefs about their ability to feed the infant in particular proved to be quite robust in predicting mothers' later perceptions of infant vulnerability. Findings collectively suggest that careful attention to the manner in which mothers of preterm infants adapt to parenthood, even before infant hospital discharge, can help clinicians identify mothers at particularly high risk of developing perceptions of infant vulnerability later in the infant's first year. Implications for intervention are discussed.
