Interventions to enhance medication adherence in pregnancy- a systematic review

Impact of early preeclampsia prediction on medication adherence and behavior change: a survey of pregnant and recently-delivered individuals

BACKGROUND

Behavior change and medication adherence represent potential barriers to optimal prevention of pregnancy complications including preeclampsia. We sought to evaluate baseline sentiments on pregnancy care and medication amenability, and how these measures would be impacted by early predictive testing for preeclampsia.

METHODS

We developed a digital survey to query participants' baseline sentiments on pregnancy care, knowledge about pregnancy complications, and views on a hypothetical test to predict preeclampsia. The survey was administered online to pregnant and recently-delivered individuals in the United States. Survey data were analyzed using pooled two-sample proportion z-tests with adjustment for multiple comparisons.

RESULTS

One thousand and twenty-two people completed the survey. 84% reported they were satisfied with their pregnancy care. Self-assessed knowledge about preeclampsia was high, with 75% of respondents reporting they have a "good understanding" of preeclampsia, but measured knowledge was low, with only 10% able to identify five common signs/symptoms of preeclampsia. Notably, 40% of participants with prior preeclampsia believed they were at average or below-average risk for recurrence. 91% of participants desired early pregnancy predictive testing for preeclampsia. If found to be at high risk for preeclampsia, 88% reported they would be more motivated to follow their provider's medication recommendations and 94% reported they would desire home blood pressure monitoring. Increased motivation to follow clinicians' medication and monitoring recommendations was observed across the full spectrum of medication amenability. Individuals who are more medication-hesitant still reported high rates of motivation to change behavior and adhere to medication recommendations if predictive testing showed a high risk of preeclampsia. Importantly, a high proportion of medication-hesitant individuals reported that if a predictive test demonstrated they were at high risk of preeclampsia, they would feel more motivated to take medications (83.0%) and aspirin (75.9%) if recommended.

CONCLUSION

While satisfaction with care is high, participants desire more information about their pregnancy health, would value predictive testing for preeclampsia, and report they would act on this information. Improved detection of at-risk individuals through objective testing combined with increased adherence to their recommended care plan may be an important step to remedy the growing gap in prevention.

Systematic Review of Outcomes for Assessment of Medication Adherence Enhancing Interventions: An ISPOR Special Interest Group Report

OBJECTIVES

The lack of universal guidance on outcome measures for evaluating medication adherence enhancing interventions (MAEIs) poses a challenge for assessing their effectiveness. This literature review aimed to provide a systematic overview of outcome measures currently used for the value assessment of MAEIs.

METHODS

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and searched MEDLINE, PsycINFO, Scopus, CINAHL, and Academic Search Complete for randomized and nonrandomized clinical trials, prospective cohort studies, model-based economic evaluations, and value frameworks published in English between January 2010 and September 2020. Two independent reviewers screened all titles and abstracts, followed by a full-text review. Due to the large number of relevant studies, data extraction was limited to articles published between January 2018 and September 2020. We collected data on the general characteristics of the study, the type of intervention, and the outcomes measured.

RESULTS

We screened 14 685 records and identified 308 articles for data extraction. Behavioral interventions were the most common (n = 143), followed by educational interventions (n = 110) and mixed-method interventions (n = 73). Outcomes were clustered into 7 categories with medication adherence (n = 286) being the most frequently measured, followed by clinical outcomes (n = 155), health-related quality of life (n = 57), resource use (n = 43), patient satisfaction (n = 31), economic outcomes (n = 18), and other outcomes (n = 76).

CONCLUSIONS

Various outcomes measures have been used to evaluate MAEIs, with only a small number of studies exploring economic and patient-reported outcomes. Future research is warranted to develop a consensus-based set of criteria for assessing MAEIs to facilitate the comparison of interventions and enable informed decision making.

Pharmacotherapy for Infertility in Ghana: A Prospective Study on Prescription Patterns and Treatment Outcomes among Women undergoing Fertility Treatment

Background

Pharmacotherapy remains a first-line and major treatment option for couples struggling with infertility, especially in sub-Saharan Africa, where other expensive alternatives are rarely available. Despite the reliance on pharmacotherapy for treating infertility in the subregion, especially for those diagnosed with unexplained infertility, little is known about the actual influence of drug therapies on conception.

Objectives

The study aimed to prospectively assess the prescription patterns and outcomes of pharmacotherapy for women undergoing fertility treatment in Ghana.

Methods

This prospective cohort study involved 482 infertile women presenting for fertility treatment in 4 fertility clinics in the Cape Coast Metropolis of Ghana between March 2019 and February 2021. A simple random sampling technique was used to recruit subjects for the study. The women were followed up for 12 months to assess the outcome of drug therapy on conception. Data analysis was done using Stata version 14. Logistic regression was used to assess the association between trends with dichotomous outcomes.

Results

The study identified that approximately 45.2% of the patients received monotherapy, whereas 24.1% received a combination of 2 drugs. Patients treated with a combination of 3 drugs were more likely to conceive (adjusted odds ratio = 4.10; 95% CI, 1.29-13.02; P = 0.02) than those without treatment.

Conclusions

Patients treated with combination therapies had higher chances of conception than those without medications. However, a combination of nutritional and herbal therapies were associated with improved outcomes compared with conventional and nutritional supplements. The study's outcome could provide fertility specialists and stakeholders insight into choosing appropriate treatment options for prospective couples seeking fertility care. Consequently, fertility patients can access specific treatment options to meet their desired needs.
