Ecological Momentary Assessment of Heavy Episodic Drinking in the Early Postpartum Period: A Feasibility Study

Background

Postpartum mothers are at heightened risk for heavy episodic drinking (HED). Research with this population is critical to developing acceptable and effective tailored interventions, but new mothers who use alcohol are often reluctant to engage in research due to stigma and fear of child removal. This study examined feasibility of recruitment and ecological momentary assessment (EMA) in early postpartum mothers with histories of HED.

Methods

Participants were recruited via Facebook and Reddit and completed 14 days of EMA surveys. Baseline characteristics, recruitment feasibility, and EMA feasibility and acceptability were examined. Participants attended focus groups to further inform quantitative data.

Results

Reddit yielded a larger proportion of eligible individuals than Facebook, and 86% of the final enroled sample was recruited via Reddit. The average compliance rate of 75% is in line with other studies of similar populations. Half the sample reported alcohol use, and 78% reported the urge to drink at least once, supporting feasibility of EMA for collecting alcohol use data. Participants reported low burden and high acceptability of the study on both quantitative and qualitative measures. Baseline low maternal self-efficacy was associated with greater EMA compliance, and first-time mothers reported lower EMA burden compared to veteran mothers. College graduates, and participants with lower drinking refusal self-efficacy and greater alcohol severity were more likely to report alcohol use on EMA.

Conclusions

Future studies should consider Reddit as a recruitment strategy. Findings generally support feasibility and acceptability of EMA to assess HED in postpartum mothers.

Patients With a Prolonged Intensive Care Unit Length of Stay Have Decreased Health-Related Quality of Life After Cardiac Surgery

Cardiac surgery patients with a prolonged ICU length of stay (prICULOS) have lower rates of functional survival following their procedure, however detailed information on their health related quality of life (HRQoL) is lacking. We sought to investigate the potential need for intervention in these high-risk patients through comprehensive HRQoL assessments in the months to year following their surgery. A prospective, observational pilot study was undertaken and cardiac surgery patients with a prICULOS (ICU length of stay of ≥5 days) were recruited. A control group was obtained through recruitment of cardiac surgery patients with an ICU length of stay of <5 days. In-person clinical or telephone survey HRQoL assessments were completed at 3-6 months and 1-year time points after their procedure. The standardized mean difference (SMD) was calculated for all study variable comparisons to quantify the standardized effect size observed between non-prICULOS and prICULOS patients. 789 cardiac procedures were performed during the study period and 89 patients experienced a prICULOS (10.7%). Of these 89 patients, 35 prICULOS patients were recruited along with 35 controls. 29 out of 35 prICULOS patients completed the study (83%). At the 3-6 month follow up the prICULOS patients had higher levels of weight loss, fear of falling, and driving deficits. At 1-year, prICULOS patients had persistent difficulties with activities of daily living and required more family and external support. This study demonstrates the need for closer follow up and intervention for cardiac surgery patients with a prICULOS who were found to have poorer mid and long-term HRQoL.
