Abstract Background Globally, mobile learning (mLearning) tools have attracted considerable attention as a means of continuous training for healthcare workers. Rwanda like other low-resource settings with scarce in-service training opportunities requires innovative approaches that adapt technology to context to improve healthcare workers’ knowledge and skills. One such innovation is the safe delivery application (SDA), a smartphone mLearning application for Basic Emergency Obstetric and Neonatal Care (BEmONC) content. This study assessed the effect of the SDA intervention on nurses’ and midwives’ knowledge and skills for the management of postpartum hemorrhage (PPH) and neonatal resuscitation (NR). Methods The study used a pre–post test design to compare knowledge and skills of nurses and midwives in the management of PPH and NR at two measurement points: immediately prior to SDA intervention and after 6 months of SDA intervention. The intervention took place in two district hospitals in Rwanda and included 54 participants. A paired-sample t-test was used to measure the pre–post intervention, mean knowledge and skills scores differences. Confidence intervals (CIs) and effect size were calculated. A t-test and a one-way Anova were used to test for potential confounders. Results The analysis included 54 participants. Knowledge scores and skills scores on PPH management and NR increased significantly from baseline to endline measurements. The mean difference for PPH knowledge is 17.1 out of 100; 95% CI 14.69 to 19.49 and 2.6% for PPH skills; 95% CI 1.01 to 4.25. The mean difference for NR knowledge is 19.1 out of 100; 95% CI 16.31 to 21.76 and 5.5% for NR skills; 95% CI 3.66 to 7.41. Increases were unaffected by participants’ attendance to in-service training 6 months prior and during SDA intervention and previous smartphone use. However, pre- and post-intervention skills scores were significantly different by years of experience in obstetric care. Conclusion The SDA intervention improved the knowledge and skills of nurses and midwives on the management of PPH and NR as long as 6 months after SDA introduction. The results are highly relevant in low-income countries like Rwanda, where quality of delivery care is challenged by a lack of in-service continuous training for healthcare providers.

Background: Hypertension is an important health problem that can be controlled by self-care. Objectives: The present study aimed to determine the impact of an educational program based (BASNEF) model on knowledge and self-care behaviors for hypertensive patients in Bastak, Iran. Methods: This quasi-experimental study was performed on 180 patients with hypertension who were admitted to health centers of the Bastak city. The participants were randomly assigned to intervention (n = 90) and control (n = 90) groups. Data were collected using a questionnaire that had three sections of demographic information, knowledge, and BASNEF constructs. The questionnaires were completed before the intervention and two months after providing the intervention. After the pre-test, an appropriate educational intervention was designed and implemented only among the intervention group. To analyze the data, paired t-test, independent t-test, and Chi-square tests were run by SPSS version 19. Results: The mean age of the participants was 50.62 ± 7.549 years. The results showed a statistically significant difference in the mean scores of attitudes, subjective norms, enabling factors, and self-care behaviors in the intervention group pre- and post-intervention (P = 0.001). Besides, it was found that enabling factors (0.311) play a significant role in predicting self-care behaviors. Conclusions: The results of this study support the effectiveness of educational interventions in raising awareness and improving self-care behaviors in patients with hypertension using the BASNEF model. Therefore, with an emphasis on enabling factors, the BASNEF model can be used as a framework to develop educational interventions for self-care.

Abstract Background: Uganda has a high neonatal mortality rate (27 per 1,000 live births), with birth asphyxia being the major contributor. Helping babies breathe (HBB) is an evidence-based program that aims to reduce neonatal mortality in resource-limited settings. Successful resuscitation depends on nurses’ and midwives’ knowledge and skills in neonatal resuscitation, and the state of neonatal resuscitation equipment. This study aimed to evaluate knowledge and skills retention in neonatal resuscitation after HBB training among nurses and midwives, and the state/availability of neonatal resuscitation equipment. Methods: This study used a cross sectional design. Participants were 75 nurses and midwives from two hospitals in Central Uganda. Data were collected using questionnaires and observation checklists. Ethics approval was obtained from the Uganda Christian University and the research and ethics committees of the participating hospitals. Results: Nurses and midwives showed a high level of knowledge (92%). However, neonatal resuscitation skills among 44 observed participants were poor, as 68.2% failed to check equipment and select the correct mask and 45.5% did not make a firm seal when applying the mask. In addition, about 72% of participants did not ventilate at a rate of 40 breaths per minute, and 18.2% failed to assess chest movement. Observation of 44 resuscitations to evaluate the state/availability of neonatal resuscitation equipment showed that 27.3% did not have a suction device, 59.1% did not have a heat source/pre-warmed towels to warm the babies, 50% did not have appropriate self-inflating bags and masks for normal and preterm babies, 72.7% had no clock/watch to count heart rate and determine the length of time ventilation was required, and 36.4% did not document that resuscitation was performed. Conclusions: To address Uganda’s neonatal mortality rate, it is necessary to develop regulatory policies for neonatal resuscitation and build nurses’ and midwives’ skills for active interventions during neonatal resuscitation.

Helping babies breathe (HBB) is an evidence-based program that aims to reduce neonatal mortality in resource-limited settings. Successful resuscitation depends on nurses’ and midwives’ knowledge and skills in neonatal resuscitation, and access to functional neonatal resuscitation equipment. This study aimed to evaluate knowledge and skills retention in neonatal resuscitation after HBB training among nurses and midwives, and the state/availability of neonatal resuscitation equipment. Methods: This study used a cross sectional design. Participants were 75 nurses and midwives from two hospitals in Central Uganda. Data were collected using questionnaires and observation checklists.

Abstract Background Previous cross-sectional studies have reported limited knowledge and practices among nurses regarding controlling nosocomial infections (NIs). Even though health institutions offer many irregular in-service training courses to solve such issues, a three year-nursing educational programme at institutions is not adequate to enable nurses to handle NIs. Therefore, this study aims to evaluate the implementation of an educational module on NIs control measures among Yemeni nurses. Methods A single-blinded randomised hospital-based trial was undertaken involving 540 nurses assigned to two intervention groups and a waitlist group. Intervention group-1 received a face-to-face training course comprising 20 h spread over six weeks and a hard copy of the module, while intervention group-2 only received the hard copy of the module “without training”. In contrast, the waitlist group did not receive anything during the period of collecting data. A self-administered NI control measures-evaluation questionnaire was utilised in collecting the data from the participants; before the intervention, at six weeks and 3 months after the end of the intervention. The period of data collection was between 1st May and 30th October 2016. Results The results from collecting and analysing the data showed a statistically significant difference in the mean knowledge scores between the intervention groups that were detectable immediately post-intervention with a mean difference (MD) of 4.31 (P < 0.001) and 3 months after the end of the intervention (MD = 4.48, P < 0.001) as compared to the waitlist group. Similarly, the results showed a statistically significant difference in the mean practice scores between the intervention groups immediately post-intervention (MD = 2.74, P < 0.001) and 3 months after the intervention (MD = 2.46, P < 0.001) as compared to the waitlist group. Intervention-1 (face-to-face training + module) was more effective than intervention-2 (module only) in improving Yemeni nurses’ knowledge and practices regarding NI control measures compared to the waitlist group. Conclusion The findings of this study found that intervention-1 could be offered to nurses in the form of an in-service training course every six months. The NI course should also be included in nursing curricula, particularly for the three-year-nursing diploma in Yemen. Trial registration Nosocomial infection educational module for nurses ISRCTN19992640, 20/6/2017. The study protocol was retrospectively registered.

Abstract Objectives To estimate the proportion of children aged 6 to 9 months who met the minimum dietary diversity and minimum meal frequency between children in CCFLS group versus children in GMP and compare their anthropometric indices 6 months post-intervention in Thyolo district. Methods Children age 6 to 9 months from Thyolo district, Nchiramwera area were individually randomised into intervention or control arm of the study. Caregivers of children in the intervention arm received CCFLS sessions while those in control arm attended standard growth monitoring promotion sessions (GMP) at their nearest facility. Data on feeding practices were collected at baseline and after six months. Furthermore, data on anthropometric indices were collected monthly for six months. CCFLS vs control group comparisons of baseline-end-line change in proportions of achieving minimum dietary diversity (MDD) and frequency (MDF) were done. Additionally, both bivariate and multivariate logistic regression analyses were done to determine the effect of CCFLS on improving MDD and MDF at six months follow up. Student's t-test was used to compare the mean six months change in anthropometric indices in the CCFLS group to the control group. Results A cohort of 168 children were randomised; 84 in the CCFLS arm and 84 in the GMP arm. There was strong evidence of an association between receiving the CCFLS intervention and achieving MDD. Adjusting for the baseline MMD proportion the children that had CCFLS had a nearly 12 times higher odds of achieving MDD compared to controls, AOR (95% C.I.) 12.43 (5.39 –28.67 p value &lt; 0.001). After 6 months follow up, the mean (95% C.I.) change in weight in the CCFLS group was + 1.45 kg (1.30–1.59) and + 1.22 kg (1.02 –1.42) in the GMP group and this was statistically significantly different (p-value 0.04 t-test). Analysis showed there was no association between receiving CCFLS intervention and achieving a change in MMF and MUAC. Conclusions Impact of CCFLS in improving MDD and weight gain is sustained post intervention, at least in the short term of 6 months follow up.

Logoterapi merupakan terapi untuk menemukan makna positif dibalik sebuah kejadian yang tidak diharapkan. Logoterapi dilaksanakan secara individu maupun berkelompok dalam bentuk konseling dan berorientasi pada pencarian makna hidup individu. Tujuan logoterapi meningkatkan makna pengalaman hidup individu yang diarahkan kepada pengambilan keputusan yang bertanggung jawab. Penelitian ini dilakukan dengan menggunakan rancangan pre-experiment dengan metode pre and post test group, artinya pengumpulan data dilakukan terhadap responden untuk membandingkan kualitas hidup sebelum dan sesudah dilakukan intervensi. Teknik pengambilan sampel dilakukan dengan metode total sampling yaitu pengambilan seluruh sampel dengan tetap memperhatikan kriteria yang telah ditetapkan. Jumlah pasien yang menjalani hemodialisis di RSUD Ungaran sebanyak 21 orang dan di RSUD Ambarawa sebanyak 25 pasien. Analisis data dilakukan dengan menggunakan uji t test dependent. Hasil penelitian didapatkan bahwa dari 46 responden didapatkan rata-rata skor kualitas hidup pasien yang mejalani hemodialisis sebesar 60.22 dengan skor terrendah 55 dan skor tertinggi 69. Bahwa dari 46 responden didapatkan rata-rata skor kualitas hidup pasien yang mejalani hemodialisis sebesar 88.72 dengan skor terrendah 79 dan skor tertinggi 103. Hasil uji statistik dengan uji t test dependent diketahui ada pengaruh logoterapi terhadap kemampuan memaknai hidup pada klien yang menjalani hemodialisis di RSUD Kabupaten Semarang (p value: 0,0001). Saran perlunya peningkatan kemampuan perawat dalam memberikan layanan kesehatan termasuk pemberian atau pemanduan penemuan makna hidup bagi pasien hemodialysis, agar selain dengan hemodialysis, ada faktor internal dari pasien yang dapat dijadikan sebagai motivasi untuk sembuh dari penyakit.   Kata Kunci: Logoterapi, kualitas hidup   IMPROVE THE QUALITY OF LIFE OF PATIENTS WITH RENAL FAILURE WHO UNDERWENT HEMODIALYSIS   ABSTRACT Logotherapy is a therapy to discover the positive meaning behind an unexpected event. Logotherapy is carried out individually or in groups in the form of counseling and oriented to the search for the meaning of individual life. This study aims to improve the quality of life of patients with renal failure who underwent hemodialysis. This research was conducted by using pre-experiment with pre-post test study. The sampling technique was done by the convenience sampling. The number of patients undergoing hemodialysis as many as 46 respondents. Data analysis was done by using test t test dependent. The result showed that from 46 respondents got the mean of quality of life of patients who had hemodialysis 60.22 with lowest score 55 and highest score 69. Whereas from 46 respondents got the mean score of life quality of patients who had hemodialysis 88.72 with score the lowest score 79 and the highest score 103. The result of statistical test with t test dependent is known there is influence of logoterapi to the ability of meaningful life on client who undergo hemodialysis at Semarang Regency hospitals (p value: 0.0001). Advice on the need to improve the nurse's ability to provide health services, including the provision or guidance of the discovery of the meaning of life for hemodialysis patients, in addition to hemodialysis, there are internal factors of the patient that can be used as a motivation to recover from illness.   Keywords: Logotherapy, quality of life, kidney failure.

BACKGROUND Exact quantification of volumetric changes of the extremities is difficult. There are several direct and indirect methods to assess extremity volume. As water displacement volumetry is rarely viable in a clinical setting and circumference measurements are prone to errors due to poor reproducibility and high inter- and intra-observer variability, an objective and easily reproducible method is indispensable. OBJECTIVE The aim of this study was to establish a standardized method based on 3D scans with defined caudal and cranial landmarks of the lower leg which allows for measurements of exactly the same body area. Furthermore, this study tests the method in terms of reproducibility and evaluates volume changes after surgical therapy in patients suffering from lymphedema. METHODS 3D-scans of the lower limb were performed with a mobile 3D-scanner. Volumetric calculation was done digitally. “Repeatability“ and “Inter-observer reliability” of digital volumetry were tested. Furthermore, the method was applied on 31 patients suffering from chronic lymphedema. ANOVA (analyses of variance) was conducted to compare the digital volumetric measurements. To assess the sensitivity to changes in digital volumetry, the mean volume of 31 patients before and 3 months after therapy were compared by a paired t-Test. RESULTS Calculations of repeatability of the volume based on 20 3D-scans of the same lower leg showed a mean volume of 2,488 ± 0,011 liters (range: 2,470 – 2,510). The mean volume of the 7 measurements of the 3 examiners did not differ significantly (F(2,18) = 1,579, p = .233). The paired t-Test showed a significant mean volume decrease of 375ml (95% CI = 245/505ml) between pre and post treatment (t (30) =5,892, p < .001). CONCLUSIONS 3D-Volumetry is a noninvasive, easy and quick method to assess volume changes of the lower leg. Other than the costs, it is reproducible and precise and therefore ideal for evolution of therapy in lymphedema.
