Each year, 3% of infants in the Unites States (US) are born with congenital anomalies, including 3000 with neural tube defects. Multivitamins (MVIs) including folic acid reduce the incidence of these birth defects. Most women do not take recommended levels of folic acid prior to conception or during the interconception period. The Interventions to Minimize Preterm and Low Birth Weight Infants through Continuous Improvement Techniques (IMPLICIT) ICC model was implemented to screen mothers who attend well child visits (WCVs) for their children aged 0–24 months. Mothers were queried for maternal behavioral risks known to affect pregnancy including multivitamin use and use of family planning methods to enhance birth spacing. When appropriate, interventions targeted at those at risk behaviors are offered. A mixed effects logistic regression model was used to calculate the odds ratio (OR) of behavior change in MVI use among mothers who reported not using MVIs. 37.7% of mothers reported not using MVIs at WCVs. 64.0% of mothers received an intervention to improve MVI use in this model. Mothers who received an intervention were more likely to report taking an MVI at the subsequent WCV if they received advice to take MVIs (OR 1.64) or directly received MVI samples (OR 3.09). Dedicated maternal counseling during pediatric WCVs is an opportunity to influence behavioral change in women at risk of becoming pregnant. Direct provision of MVIs increases the odds that women will report taking them at a higher rate than provider advice or no counseling at all.

Introduction: Adequate maternal nutrition before pregnancy is important to reduce the risk of poor birth outcomes. However, patients report suboptimal intake of multivitamins with folic acid (MVIs). Methods: We conducted a quality improvement study to identify predictors of insufficient multivitamin use in women of childbearing age at five University of Pittsburgh Medical Center (UPMC) family health centers that implemented the IMPLICIT interconception care (ICC) model of maternal health screenings during well-child visits (WCVs). We derived this analysis from a retrospective chart review of patient-reported demographic information and physician documented maternal behaviors of 758 women who accompanied their children to 2,706 total well-child visits. Insufficient multivitamin use was defined as having one or more visits where the mother reported that she was not taking multivitamins. Results: Insufficient multivitamin use at these health centers was associated with younger age (OR 0.96, 95% CI 0.92, 0.98), less than high school education (OR 3.3, 95% CI 1.56-6.80), public insurance (OR 1.56, 95% CI 1.05-2.34), and increased number of well-child visits attended (OR 1.46, 95% CI 1.31-1.61). Conclusion: Among women who received screening, younger, low-income, and less educated women are likely to benefit from targeted interventions to improve multivitamin use during the interconception period. Findings also suggest that WCVs are a viable access point to assess and address multivitamin use and other desired maternal health behaviors.

Background Preterm birth, birth defects, and unintended pregnancy are major sources of infant and maternal morbidity, mortality, and associated resource use in American health care. Interconception Care (ICC) is recommended as a strategy to improve birth outcomes by modifying maternal risks between pregnancies, but no established model currently exists. The Interventions to Minimize Preterm and Low Birth Weight Infants through Continuous Improvement Techniques (IMPLICIT) Network developed and implemented a unique approach to ICC by assessing mothers during their baby's well-child visits (WCVs) up to 24 months. Methods Mothers who accompanied their children to WCVs at eleven eastern US family medicine residency programs underwent screening for four risk factors (tobacco use, depression risk, contraception use to avoid unintended pregnancy and prolong interpregnancy interval, and use of a multivitamin with folic acid). Positive screens in women were addressed through brief interventions or referrals to treatment. Results Mothers accompanied their babies to 92.7% of WCVs. At more than half of WCVs (69.1%), mothers were screened for presence of ICC behavioral risks, although significant practice variation existed. Risk factors were identified at significant rates (tobacco use, 16.2%; depression risk, 8.1%; lack of contraception use, 28.2%; lack of multivitamin use, 45.4%). Women screened positive for 1 or more ICC risk factor at 64.6% of WCVs. Rates of documented interventions for women who screened positive were also substantial (tobacco use, 80.0%; depression risk, 92.8%; lack of contraception use, 76.0%; lack of multivitamin use, 58.2%). Conclusion WCVs provide a reliable point of contact with mothers and a unique opportunity to assess and address behavioral risks for future poor birth outcomes.

ContextDiagnosis of Parkinson disease (PD) remains challenging. An accurate diagnosis is important because effective symptomatic treatment for PD is available.ObjectiveTo systematically review the literature for information on the precision and accuracy of the clinical examination for diagnosing PD.Data SourcesMEDLINE database was searched for all English-language articles related to the diagnosis of PD published from January 1966 through April 2001. The reference lists of all articles retrieved were searched for additional relevant sources.Study SelectionStudies in which patients presented with 1 or more typical features of PD were included if the final diagnosis was confirmed by a suitable criterion standard and data could be extracted to determine the accuracy of 1 or more symptoms or signs. Variability in descriptions of symptoms and signs made it impossible to combine data across existing studies for most findings.Data SynthesisWe identified 6 studies that met our criteria. The positive (presence) likelihood ratios (LRs) for tremor as a symptom of PD ranged from 1.3 to 17 (range of negative [absence] LRs, 0.24 to 0.60). Tremor as a sign of PD produced a range of positive LRs from 1.3 to 1.5 (negative LRs, 0.47 to 0.61). Clinical features useful in the diagnosis of PD include a history of the combination of symptoms of rigidity and bradykinesia (positive LR, 4.5; negative LR, 0.12); a history of loss of balance (range of positive LRs, 1.6 to 6.6; range of negative LRs, 0.29 to 0.35), symptoms of micrographia (range of positive LRs, 2.8 to 5.9; range of negative LRs, 0.30 to 0.44), and a history of shuffling gait (range of positive LRs, 3.3 to 15; range of negative LRs, 0.32 to 0.50). Trouble with certain tasks such as turning in bed (positive LR, 13; negative LR, 0.56), opening jars (positive LR, 6.1; negative LR, 0.26), and rising from a chair (range of positive LRs, 1.9 to 5.2; range of negative LRs, 0.39 to 0.58). Useful signs include the glabella tap test (positive LR, 4.5; negative LR, 0.13), difficulty walking heel-to-toe (positive LR, 2.9; negative LR, 0.32), and rigidity (range of positive LRs, 0.53 to 2.8; range of negative LRs, 0.38 to 1.6). Significant selection bias was detected in all studies included for review.ConclusionsSymptoms of tremor, rigidity, bradykinesia, micrographia, shuffling gait, and difficulty with the tasks of turning in bed, opening jars, and rising from a chair should be carefully reviewed in all patients with suspected PD. The glabella tap and heel-to-toe tests also should be assessed.
