Applying a multiple screening program aided by a guideline-driven computerized decision support system - a pilot experience in Yun-Lin, Taiwan

Previously undiagnosed risk factors and medication nonadherence are prevalent in young adults with first-ever stroke

PURPOSE

The incidence of stroke and prevalence of traditional vascular risk factors (VRFs) in young adults (age < 55 y) are both increasing. Young patients tend to be unaware of their VRFs and to have lower medication adherence. We examined how age affects the prevalence of previously undiagnosed VRFs and the extent of medication nonadherence among stroke patients.

METHODS

Using Taiwan's National Health Insurance Research Database, we identified consecutive adult patients with first-ever stroke between 2000 and 2013. Diagnosis of hypertension, diabetes, and hyperlipidemia was ascertained using validated methods. We investigated (1) the proportion of patients who had undiagnosed VRFs within 3 years before stroke and (2) the proportion of nonadherence to medications among patients who had a previously diagnosed VRF.

RESULTS

Among stroke patients with hypertension (n = 9722), diabetes (n = 4751), and hyperlipidemia (n = 4486), 24.9%, 20.8%, and 55.0%, respectively, had not been diagnosed before stroke, whereas 56.0%, 66.7%, and 32.5%, respectively, had been diagnosed at least 1 year before stroke. The proportions of medication nonadherence were 71.5%, 64.3%, and 88.4% in patients with previously diagnosed hypertension, diabetes, and hyperlipidemia, respectively. In multivariate analysis, younger age was independently associated with undiagnosed hypertension before stroke as well as medication nonadherence in patients with previously diagnosed hypertension or diabetes.

CONCLUSIONS

Previously undiagnosed hypertension and nonadherence to treatment of hypertension and diabetes were more prevalent in young adult patients with first-ever stroke in Taiwan. Interventions targeting young people to promote early detection and adequate control of VRFs should be encouraged.

Use of patient decision aids increased younger women's reluctance to begin screening mammography: a systematic review and meta-analysis

BACKGROUND

As breast cancer screening guidelines have changed recently, additional investigation is needed to understand changes in women's behavior after using breast cancer screening patient decision aids (BCS-PtDAs) and the potential effect on mammography utilization. This systematic review and meta-analysis sought to evaluate the effect of BCS-PtDAs on changes in women's intentions to undergo screening mammography and whether women deciding to begin or discontinue screening mammography displayed similar changes in screening intentions after using a BCS-PtDA.

METHODS

We searched Medline, Scopus, PsycINFO, CENTRAL, Health and Psychosocial Instruments, Health Technology Assessment Database, PsycARTICLES, and cited references in eligible papers for randomized controlled trials (RCTs) and observational studies, published through August 24, 2016. The proportions of women who did and not intend to undergo screening and who were uncertain about undergoing screening mammography were pooled, using risk ratios (RR) and random effects. According to the protocol, RCTs or observational studies and any language were considered eligible for systematic review if they included data about women for which shared decision making is recommended.

RESULTS

We ultimately included six studies with screening intention data for 2040 women. Compared to usual care, the use of BCS-PtDAs in three RCTs resulted in significantly more women deciding not to undergo screening mammography (RR 1.48 [95% CI 1.04-2.13]; P = 0.03), particularly for younger (38-50 years) women (1.77 [1.34-2.34]; P < 0.001). The use of BCS-PtDAs had a non-significant effect on the intentions of older women (69-89 years) to discontinue screening.

CONCLUSIONS

The use of BCS-PtDAs increased younger women's reluctance to undergo screening for breast cancer. The implementation of such BCS-PtDAs in clinical practice would be expected to result in a 77% increase in the number of younger women (aged 38-50) who do not intend to be screened, and as a consequence, may reduce utilization of screening mammography.

The DSCP-CA: a decision support computer program--cancer pain management

The purpose of this study was to develop a decision support system using fuzzy logic that would support nurses' decisions about cancer pain management, especially for ethnic minority cancer patients. The study had two phases: (1) data collection and (2) development of the decision support computer program. In the data collection phase, an Internet survey of 428 cancer patients and four ethnic-specific online forums (about 30 participants per forum) were conducted to gather data on the cancer pain experience of the four major ethnic groups in the United States. The development phase included two components: (1) development of three modules, including a knowledge base module, a decision module, and a self-adaptation module; and (2) a 3-month evaluation of the decision support computer program by oncology nurses and subsequent incorporation of their feedback into the program. The Internet survey and online forum data were processed into fuzzy and crisp data sets, and ethnic-specific algorithms for the decision module were developed. Using the self-adaptation module, the decision support computer program was further refined as additional data were processed. Then, the decision support computer program was further developed by adding additional components suggested by the oncology nurses.

Expert recommendations on the challenges of hypertension in Asia

A consensus meeting of leading Asian hypertension experts was held in January 2007 in Seoul, Korea, to discuss how to address the growing challenge of hypertension management in the region. This report summarises key recommendations from the group, including: raising public awareness about the impact of hypertension; improving physician education and training; increasing early detection, for example through routine blood pressure measurement; and development and adoption of pan-Asian treatment guidelines, which would greatly facilitate research into hypertension and its management. The group conclude that these challenges can only be met through a collaborative effort of government, healthcare professionals, food and healthcare industries, and patients and the public. Food and healthcare industries need to develop healthy foods and support healthy living programmes, while increasing research into antihypertensive medications in Asia. Government officials and policy makers need to be made aware of the value of investing in hypertension awareness, prevention and management programmes.
