Background: It is important to know the decay of knowledge, skills, and confidence over time to provide evidence-based guidance on timing of follow-up training. Studies addressing retention of simulation-based education reveal mixed results. The aim of this study was to measure the level of knowledge, skills, and confidence before, immediately after, and nine months after simulation-based training in obstetric care in order to understand the impact of training on these components. Methods: An educational intervention study was carried out in 2012 in a rural referral hospital in Northern Tanzania. Eighty-nine healthcare workers of different cadres were trained in “Helping Mothers Survive Bleeding After Birth”, which addresses basic delivery skills including active management of third stage of labour and management of postpartum haemorrhage (PPH). Knowledge, skills, and confidence were tested before, immediately after, and nine months after training amongst 38 healthcare workers. Knowledge was tested by completing a written 26-item multiple-choice questionnaire. Skills were tested in two simulated scenarios “basic delivery” and “management of PPH”. Confidence in active management of third stage of labour, management of PPH, determination of completeness of the placenta, bimanual uterine compression, and accessing advanced care was self-assessed using a written 5-item questionnaire. Results: Mean knowledge scores increased immediately after training from 70 % to 77 %, but decreased close to pre-training levels (72 %) at nine-month follow-up (p = 0.386) (all p-levels are compared to pre-training). The mean score in basic delivery skills increased after training from 43 % to 51 %, and was 49 % after nine months (p = 0.165). Mean scores of management of PPH increased from 39 % to 51 % and were sustained at 50 % at nine months (p = 0.003). Bimanual uterine compression skills increased from 19 % before, to 43 % immediately after, to 48 % nine months after training (p = 0.000). Confidence increased immediately after training, and was largely retained at nine-month follow-up. Conclusions: Training resulted in an immediate increase in knowledge, skills, and confidence. While knowledge and simulated basic delivery skills decayed after nine months, confidence and simulated obstetric emergency skills were largely retained. These findings indicate a need for continuation of training. Future research should focus on the frequency and dosage of follow-up training.
An educational intervention study with pre-, post-, and nine-month follow-up assessments was performed from March to December 2012. The Helping Mothers Survive Bleeding After Birth simulation-based training programme was introduced in a rural referral hospital in Northern Tanzania in March 2012. A cross-sectional study that took place in this hospital from November 2009 until November 2011 showed that the maternal mortality ratio was 350 maternal deaths per 100,000 live births (95 % confidence interval: 243–488) [12]. PPH accounted for 27 % of all maternal morbidity and mortality, and the case fatality rate of PPH was as high as 9 % [12]. During the time of this study, the hospital had 420 beds and provided free reproductive services and comprehensive emergency obstetric care. The annual number of births in this period was approximately 4,700 [13]. Helping Mothers Survive Bleeding After Birth uses a train-the-trainer model in which training is cascaded down from master trainers to local facilitators to learners [14]. In two sessions, four master trainers trained eight local facilitators in a one-to-one ratio. Training of local facilitators lasted a full day and consisted of a half-day theory and a half-day skills and scenario teaching regarding basic delivery skills including active management of third stage of labour and management of PPH. Subsequently, these eight facilitators trained 89 local learners in half-day sessions under supervision of master trainers. The number of learners per facilitator ranged from three to six. Clinicians, nurse-midwives, medical attendants (nurse aides without formal medical education), ambulance drivers (without formal medical education), and other staff involved in maternity care (including nurse-midwives from the intensive care unit and operating theatre), were selected by the hospital management to attend training. Due to logistical reasons, only participants working on labour ward, ambulance drivers, and facilitators were enrolled for testing, thus rendering 38 out of the original 89 learners eligible for analysis. Checking competency (or validation) of local facilitators by means of knowledge and skills testing was done after teaching learners. Further details of the training are described elsewhere [3]. The study design was based on the four levels of Kirkpatrick’s model for evaluation of training programmes [15]. In this paper, we report on Kirkpatrick level 2 (learning), for which we have measured changes in knowledge, skills, and confidence due to training. The assessment tools and their validation have been described in detail previously [3]. In brief, knowledge, skills, and confidence were tested on three occasions; immediately before training, immediately after training, and nine months after training. Knowledge about basic delivery skills, active management of third stage of labour, and management of PPH was tested using a written 26-item multiple-choice questionnaire. The criterion-referenced pass score was ≥ 70 % correct answers. The test was developed and assessed for face, content, and construct validity by Jhpiego, of which the details are described elsewhere [3]. Skills performance was assessed in two simulated scenarios using a low-cost, low-tech birthing simulator (MamaNatalie, Laerdal Global Health): “basic delivery” and “management of PPH”. A checklist for the assessment of skills performance was developed and validated by the authors [3]. To pass the test, five essential items for basic delivery, and eight essential items for management of PPH were identified that needed to be performed. Each participant’s skills test was videotaped and subsequently assessed by two independent assessors, who were blinded for the time of testing. Confidence of participants to perform active management of third stage of labour, manage PPH, determine completeness of the placenta, perform bimanual uterine compression, and access advanced care was self-assessed using a questionnaire. Five answers were possible, ranging from 1 = I cannot perform this skill to 5 = extremely confident. At the nine-month assessment all facilitators and learners were interviewed about the number of deliveries performed since initial training, as well as the number of bimanual uterine compressions performed, the number of times MamaNatalie was used for practise, and the participation in any other practise or training regarding basic delivery and management of PPH. All assessment materials were available in two languages, English and Kiswahili (local language). Data was double entered in EpiData (The EpiData Association, Odense, Denmark), and analysed using IBM SPSS Statistics, version 20 (IBM, Armonk, NY, USA). Descriptive statistics were calculated for participant characteristics, exposure to clinical work and training during the follow-up time, knowledge, skills, and confidence. Results are reported as number (n), percentage (%), mean, standard deviation (SD), and range. Statistical analyses of the changes from pre-training assessment to nine-month follow-up and from post-training to nine-month follow-up included McNemar’s test for categorical values, and paired samples t-test for continuous values. Ethical approval was obtained from the Tanzanian National Institute for Medical Research (reference NIMR/HQ/R.8a/Vol.IX/1247), the Tanzania Commission for Science and Technology (reference 2013-41-ER-2011-201), and from the VU University Medical Centre, the Netherlands (reference 2011/389). Permission to conduct the study was obtained from the hospital management. Written informed consent was obtained from each participant before entering the study.
