Couples diagnosed with unexplained subfertility are advised to start mild ovarian hyperstimulation and intrauterine insemination (MOH-IUI) as a primary treatment. Natural feedback mechanisms and hormone release are affected by artificially stimulated cycles and induced ovulation. Additional luteal support could positively affect progesterone patterns in the luteal phase. The LUMO study evaluates whether the addition of exogenous progesterone in the luteal phase following MOH-IUI treatment cycle will improve pregnancy and live birth rates.
A multicentre randomised, double-blind, controlled trial will be conducted in Dutch fertility clinics, academic and non-academic hospitals. There are two treatment arms: group A progesterone luteal phase support; group B placebo, without crossover. All initiated MOH-IUI cycles within 6 months after randomisation are included (study period). Participants will start study medication, applying a daily dosage of 2dd 300 mg progesterone (Utrogestan) or 2dd 300 mg placebo in vaginal capsules on the second day after the IUI procedure. Treatment is continued until the onset of menstruation, a negative pregnancy test (IUI+14 days), a miscarriage or until 7 weeks of gestation in case of a viable pregnancy. Follow-up ends at 12 months after the end of study period (18 months after study randomisation). The primary outcome is cumulative pregnancy rate, achieved within 6 months after randomisation, leading to live birth. A total of 1008 patients (504 patients in each group) will be included.
The study was approved by the Central Committee on Research Involving Human Subjects on 30 January 2023. All participating sites have the approval of the local Board of Directors to participate in the LUMO study. An informed consent form will be signed by all participants. Study results will be presented at (inter)national conferences and published in peer-reviewed journals. It is expected that the results of this trial will be used to draft national guidelines on this issue.
The study is registered in the EU CTIS trial register (2022-501534-33-00), the Dutch trial registry (registration number: LTR 24508), ClinicalTrials.gov (NCT05080569) and the WHO registry (universal trial number: U1111-1280-9461).
To investigate the effects of active involvement of family caregivers in adult in-hospital care on patients' readmissions, complications, mortality, length of hospital stay, quality of life, psychological distress and activities of daily living, as well as on the satisfaction of patients, HCPs and family caregivers.
Systematic review.
Ovid Medline, Ovid Embase, EBSCO CINAHL, Cochrane Library (from inception to February 2024).
The PRISMA 2020 statement was followed. Prospective controlled studies focusing on active involvement of family caregivers in adult in-hospital care were included. Two independent teams of authors conducted study selection, quality assessment and data extraction.
Thirteen studies were included, comprising 11 randomised controlled trials. The clinical and methodological heterogeneity precluded a meta-analysis. Six of these studies were performed in stroke patients. Some studies reported statistically significant benefits of active family involvement on readmission rates, hospital LOS, ADL, psychological distress for patients and family members, QoL and satisfaction of family caregivers. However, others did not observe differences in these outcomes. For complication rates, mortality and satisfaction of patients and HCPs, no studies demonstrated significant differences between groups.
Further research is needed to provide a conclusive answer as to whether active family caregiver involvement improves outcomes of adult hospitalised patients.
Despite the inconclusive findings of this review, advocating for active involvement of family caregivers in adult in-hospital care fits the perspective of patient- and family-centred care.
As the care of hospitalised adults is shifting to a more family-centric approach, investigating the effects of an active role of family caregivers in adult in-hospital care is necessary. However, the small number of studies available and heterogeneity between studies included in this review hamper firm conclusions. Further evaluations through well-designed studies are required.
