RESUMO

BACKGROUND: Research indicates that the effectiveness of coronavirus disease 2019 (COVID-19) physical distancing mandates is influenced by several individual factors, including health literacy; internal health locus of control (IHLOC), the belief that physical distancing can reduce COVID-19 risk; social norms; self-efficacy; and perceptions of the benefits and barriers associated with distancing. However, further investigation is needed to understand the links between these factors and compliance intentions. OBJECTIVE: This study investigates the mechanism linking these factors with the intentions to comply with physical distancing mandates. METHODS: A total of 759 participants (Mean age = 29.13, standard deviation [SD] = 8.33; 68.5% women) were surveyed online from September 2020 to October 2020. Data were analyzed using ANOVA (analysis of variance) and structural equation modeling. KEY RESULTS: Health literacy was associated with more perceived benefits (ß = .175, p = .001), greater self-efficacy (ß = .193, p < .001), and less perceived barriers (ß = -.391, p < .001). IHLOC was significantly associated with greater perceived benefits (ß = .156, p = .007) and self-efficacy (ß = .294, p < .001). Family descriptive norms were significantly associated with fewer perceived barriers (ß = -.276, p < .001), while injunctive norms were associated with more perceived benefits (ß = .202, p = .001) and higher self-efficacy (ß = .299, p < .001). Intentions to adhere to physical distancing mandates were significantly associated with past compliance (ß = .427, p < .001) and perceived barriers (ß = -.205, p < .001) and benefits (ß = .295, p < .001). Post-hoc mediation analyses revealed several small yet significant indirect effects, highlighting the complex pathways shaping adherence intentions. CONCLUSIONS: This study identifies how health literacy, IHLOC, social norms, perceived benefits and barriers, and self-efficacy intricately shape intentions to comply with physical distancing mandates. These findings offer valuable implications for public health policy and interventions. [HLRP: Health Literacy Research and Practice. 2024;8(2):e69-e78.].


PLAIN LANGUAGE SUMMARY: This study examined the factors associated with Omanis' intentions to comply with physical distancing mandates during COVID-19. Results revealed that individuals with higher health literacy perceived fewer barriers and more benefits to physical distancing, making them more willing to comply with mandates. Those who believed their actions could reduce the risk of contracting the virus also reported greater benefits and were more likely to comply.

RESUMO

BACKGROUND: Contagious caprine pleuropneumonia (CCPP) is a fatal WOAH-listed, respiratory disease in small ruminants with goats as primary hosts that is caused by Mycoplasma capricolum subspecies capripneumoniae (Mccp). Twelve CCPP outbreaks were investigated in 11 goat herds and a herd of captive Arabian sand gazelle (Gazella marica) in four Omani governorates by clinical pathological and molecular analysis to compare disease manifestation and Mccp genetic profiles in goats and wild ungulates. RESULTS: The CCPP forms in diseased and necropsied goats varied from peracute (5.8%), acute (79.2%) and chronic (4.5%) while all of the five necropsied gazelles showed the acute form based on the clinical picture, gross and histopathological evaluation. Colonies of Mccp were recovered from cultured pleural fluid, but not from lung tissue samples of one gazelle and nine goats and all the isolates were confirmed by Mccp-specific real time PCR. Whole genome-single nucleotide polymorphism (SNP) analysis was performed on the ten isolates sequenced in this study and twenty sequences retrieved from the Genbank database. The Mccp strains from Oman clustered all in phylogroup A together with strains from East Africa and one strain from Qatar. A low variability of around 125 SNPs was seen in the investigated Omani isolates from both goats and gazelles indicating mutual transmission of the pathogen between wildlife and goats. CONCLUSION: Recent outbreaks of CCPP in Northern Oman are caused by Mccp strains of the East African Phylogroup A which can infect goats and captive gazelles likewise. Therefore, wild and captive ungulates should be considered as reservoirs and included in CCPP surveillance measures.

RESUMO

BACKGROUND: Children and adolescents diagnosed with cancer often experience psychological distress, encompassing anxiety, depression, and post-traumatic stress disorder (PTSD). This study aimed to evaluate the prevalence of these conditions among Omani children and adolescents diagnosed with cancer, alongside identifying contributing factors. METHODS: A prospective cross-sectional study was conducted from October 2021 to June 2023 among a cohort of Omani children and adolescents (6-18 years old) diagnosed with cancer at three primary cancer referral centres in Oman. Validated Arabic-language versions of the Screen for Child Anxiety Related Disorders, the Center for Epidemiologic Studies Depression Scale for Children, and the Impact of Event Scale-Revised instruments were used to assess symptoms of anxiety, depression, and PTSD, respectively. An initial assessment (T1) was undertaken within the first 3 months of diagnosis, followed by a second assessment (T2) 3-6 months later. RESULTS: Of 113 eligible participants, 101 agreed to participate in the study (response rate: 95.6%), with 92 (91.0%) completing both assessments and included in the final analysis. Prevalence rates of anxiety, depression, and PTSD decreased from 43.5%, 56.5%, and 32.6%, respectively, at T1, to 38.0%, 35.9%, and 23.9% at T2. All average scores were below diagnostic cut-off points, except for the depression score at T1. Anxiety and depression scores decreased significantly (p = 0.043 and 0.001, respectively) between T1 and T2, as did the overall prevalence of depression (p = 0.004). At T1, linear regression analysis showed significant correlations between anxiety scores and the child's age and PTSD score (p < 0.05); these variables were also correlated with depression scores (p ≤ 0.001). At T2, significant correlations were observed between anxiety scores and the child's age and PTSD scores (p < 0.001). At both T1 and T2, anxiety, depression, and PTSD scores remained significantly correlated (p < 0.001). CONCLUSIONS: Omani children and adolescents recently diagnosed with cancer exhibit a high prevalence of anxiety, depression, and PTSD over time. Age-appropriate communication, ongoing support, and mental health services are recommended to help this patient group cope with their diagnosis and manage their emotional wellbeing. There is a need for future research to determine the effectiveness of specific psychological interventions in reducing the frequency of these disorders.

RESUMO

BACKGROUND: Cancer is widely considered as one of the most stigmatized diseases globally, despite scientific advances in the medicine. While most existing literatures focuses on cancer stigma as perceived by patients, there has been limited research on  stigma towards cancer among the non-cancer population. In 2014, Marlow et al developed and validated the "Cancer Stigma Scale" (CASS) specifically for the non-Cancer population. This study aims to quantitatively evaluate cancer stigma within the non-patient population in Oman. METHODS: This is a cross-sectional study conducted in Oman. The Cancer Stigma Scale (CASS) has been used to evaluate the cancer-related stigma among the non-cancer patient population in Oman. RESULTS: A total of 510 participants completed the survey of whom 57.6% were male. The personal responsibility section had the highest mean score, followed by the avoidance and financial discrimination. The lowest mean scores were observed in the danger and policy opposition sections. Female participants showed ore disagreement  with cancer stigma statements compared to males. Participants who knew someone with cancer expressed more disagreement with stigma statements than those  who did not know anyone with cancer. CONCLUSION: This study provides a baseline measurement of  cancer-related stigma among non-cancer patients in Oman, tilizing the CASS in a representative sample of the population. The results indicate generally low levels of stigma, though certain aspects are more pronounced, varying according to the participants' gender, age, and personal connections to someone with cancer.

RESUMO

OBJECTIVE: This study aimed to reduce the number of patients discharged without scheduled follow-up appointments by implementing lean management principles. METHODS: Conducted at the Sultan Qaboos Comprehensive Cancer Center in Muscat, Oman, the research utilized a one-group pretest-posttest quasi-experimental design to evaluate the impact of lean management interventions on the rate of patient discharges without follow-up appointments. Strategies such as the Kaizen principle, Gemba Walks, cross-functional collaboration, standard work procedures, and waste reduction were employed to enhance operational efficiency. RESULTS: Spanning from Quarter 3 of 2022 to Quarter 2 of 2023, the study demonstrated a significant decrease in the percentage of patients discharged without planned follow-up appointments. The rate dropped from 9% in September 2022 to 0% in March 2023, with statistically significant differences observed (X2= 65.05, p value=<.0001). CONCLUSION: By effectively implementing lean management principles, this research successfully enhanced care continuity for oncology patients after being discharged.

RESUMO

Type 2 diabetes mellitus (T2DM) has become a major public health concern, causing significant disability and death worldwide. Fuelled by a modern sedentary lifestyle and poor dietary practices, T2DM affects at least 10.5% of the world's population. This paper seeks to review the progress made by the Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates) in addressing T2DM, focusing on glycaemic control proportions and comparing it with the 2015 review. The results indicate no significant improvement in glycaemic control proportions since the last review, with only 9.2% to 56.9% of patients having good control (glycosylated haemoglobin < 7%). However, there are no significant differences in glycaemic control between the GCC countries and other places worldwide despite being considered hotbeds of T2DM. Many factors contribute to poor glycaemic control. Specifically, evidence shows that being overweight or obese is the most common modifiable risk factor for T2DM incidence and poor glycaemic control. The GCC countries have higher rates of obesity. Additionally, poor glycaemic control is mainly related to a lack of adherence to insulin and medication use. Poor diet, rich in calories and low in fruits and vegetables, and a sedentary lifestyle also significantly contribute to poor glycaemic control and obesity. Therefore, to reduce the incidence of disease and improve glycaemic control in diabetic patients, educational programs promoting lifestyle changes should be implemented. Ongoing research is also necessary to assess the trend of glycaemic control and its risk factors in our region.

RESUMO

Reports from different parts of the world suggest that the COVID-19 pandemic and the resultant lockdown and social distancing measures have heralded unprecedented mental health challenges among children and adolescents. To date, there is a dearth of studies emerging from the Arabian Gulf, where the majority of its population are children and adolescents. The study aims to examine the prevalence of anxiety-related symptoms and their covariates among children and adolescents in an Arabian Gulf country, Oman. This is a cross-sectional analytic study carried out over two weeks (1st to 15th of August 2020) during the COVID-19 pandemic across Oman. Parents were asked to complete the online survey, which consisted of the parent version of the Screen for Child Anxiety Related Emotional Disorders (SCARED) instrument and questions regarding basic socio-demographic information. Logistic regression was used to identify the contributing variables associated with anxiety-related symptoms. A total of 790 valid responses were received. Among the 790 children, 33.3% (n = 263) were diagnosed with anxiety-related symptoms by the SCARED instrument. Logistic regression analysis suggested that anxiety-related symptoms in children and adolescents were significantly associated with three demographic variables. The model shows that children with divorced or separated parents were 1.9 times more likely to have anxiety-related symptoms than children of married couples (OR = 1.93, p = 0.035). Children living in families with an income below USD 1000/month, were 1.8 times more likely to have anxiety-related symptoms than a family with an income of USD 4000/month (OR = 1.833, p = 0.018). Children in grades 3-6 were 1.8 times more likely to have anxiety-related symptoms than those in grades 1-2 (OR = 1.79, p = 0.024). Anxiety-related symptoms are common among Omani children and adolescents. They are more likely to be reported in middle scholastic grade levels and children from families with marital discord and low socioeconomic status. It is not clear whether the presently observed rates of anxiety exceed the prevalence that would have been observed prior to the COVID-19 pandemic. More studies are therefore warranted using children and adolescents' self-reported scales.

RESUMO

Objectives: This study aimed to evaluate the level of adherence to medication among patients with ischaemic heart disease (IHD) in Oman and assess the related factors. Methods: This cross-sectional questionnaire-based study among patients with IHD attending the outpatient clinic at Sultan Qaboos University Hospital, Muscat, Oman, was performed between January and December 2021. Results: A total of 105 patients (mean age = 49.9 ± 11.1 years, 78.1% male) were recruited. Most of the patients (80%) reported taking the medications by themselves; 77 (73.3%) patients said that over the preceding 2 weeks, they had missed at least 3 doses of their medication. The reasons for missing the medications included forgetting (100%), having to take too many tablets (57%), feeling that the tablets are not effective (48%) and having to take the tablets too often each day (23%). The factors responsible for patients failing to take medications could not be identified. Conclusion: Medication adherence was low among patients with IHD in Oman, with high pill burden being the most common reason for non-adherence. Physicians must bear this in mind when reviewing patients.

RESUMO

Objectives: This study aimed to determine the risk factors associated with the failure of arteriovenous fistulae (AVF) maturation. Methods: This retrospective cohort study was conducted from January 2014 to December 2018 in Sultan Qaboos University Hospital, Muscat, Oman. Patients were followed-up 3 months after surgery, and their electronic medical records were accessed for demographic and clinical data. Univariate analysis was used to determine the risk factors associated with early AVF maturation and multivariant analysis was used to determine the predictive factors for AVF failure. Results: A total of 269 patients were included. Female gender was a significant factor affecting AVF maturity (P = 0.049), while age (P = 0.626), diabetes (P = 0.954), hypertension (P = 0.378), dyslipidaemia (P = 0.907), coronary artery disease (P = 0.576), cerebrovascular accident (P = 0.864), congestive heart failure (P = 0.685), previous central venous catheterisation (P = 0.05), fistula type (P = 0.863) and fistula site (P = 0.861) did not affect AVF maturation. Binary logistic regression showed that all the risk factors were insignificant. Failure of early AVF maturation affected 11.5% in the cohort. Conclusion: This study found that the proportion of early AVF maturation at our hospital is at par with that in the international literature. Failure of AVF maturation was significantly associated with the female gender. These findings can help nephrologists and vascular surgeons prognosticate AVF maturation rates. However, a larger study is needed for definitive conclusions.

RESUMO

Objectives: This study aimed to review the blood stream infections of major burn patients in a tertiary care burn unit to determine the most prevalent infecting organisms in order to have a better empirical therapy protocol. Methods: This retrospective study analysed the blood stream infection of 155 major burn (>20% Total Body Surface Area [TBSA]) patients in Khoula Hospital, Muscat, Oman between January 2014 to December 2019. Results: The median age was 33 years and 57.42% of patients were male. The median TBSA was 38%, mortality was 25.16% and 50.9% of patients had positive blood cultures. The expired patients had higher TBSAs, Abbreviated Burns Severity Index scores and earlier first positive blood cultures. Candida was commonly grown in all the blood cultures, but the most prevalent organisms were Acinetobacter, Staphylococci, Klebsiella, Enterococcus and Pseudomonas. All Acinetobacter species are multidrug resistant. Of the 17 patients who had Kelbsiella grown in the blood culture, 8 grew multidrug-resistant Klebsiella. Only 4 patients' blood cultures grew methicillin-resistant Staphylococcus aureus. The number of blood culture samples taken ranged between 1-28 (median = 6). The first positive blood culture showed that Staphylococcus epidermidis and Acinetobacter were the most common infecting organisms. Conclusions: Multidrug-resistant Acinetobacter was the most predominant microorganism grown from the blood cultures of major burn patients in a tertiary care burn unit. Empirical therapy should include antibiotics that are effective against this organism to reduce the mortality.

RESUMO

Objectives: This study aimed to compare the high-flow nasal oxygen (HFNO) and supraglottic airway device (SAD) techniques in oncological patients undergoing endobronchial ultrasound (EBUS) and transbronchial needle aspiration (TBNA) to evaluate the efficacy of HFNO in them. Methods: This pilot study was conducted at Sultan Qaboos Comprehensive Cancer Care and Research Centre, Muscat, Oman, from May 2022 to March 2023. Patients undergoing EBUS TBNA under moderate sedation were quasi-randomised into the HFNO and SAD groups. The episodes and duration of hypoxia and the lowest level of oxygen saturation were the primary outcomes measured. Results: A total of 24 patients were included in the study (10 of them were in the HFNO group and 14 were in the SAD group), with an equal number of males and females. The duration of the procedure in both groups was similar (45 ± 20 and 44 ± 17 minutes in the HFNO and SAD groups, respectively). The mean lowest oxygen saturation in the HFNO group was 93.5 ± 4.5%, which was significantly higher than that of the SAD group (90 ± 3%; P <0.001). In both groups, maximum hypoxia occurred during the early phase of the procedure. However, the HFNO and SAD groups were similar in terms of the cumulative duration of hypotension (140 versus 95 seconds, respectively) and bradycardia (25 versus 40 seconds, respectively). Conclusion: HFNO is a good alternative to SAD and could be used safely and efficiently in patients undergoing EBUS TBNA.

RESUMO

OBJECTIVES: The utilisation of tele-mental health services has the potential to address challenges in mental health services within the Eastern Mediterranean Region. However, the adoption of tele-mental health in Oman remains limited. Therefore, this study aimed to explore the experiences of psychiatrists with telephone consultations, offering valuable insights to advance the field of telepsychiatry. DESIGN: This is a qualitative exploratory study. The analysis of the data involved the application of manifest content analysis. SETTING: The semi-structured interviews were conducted with the psychiatrists at Al Masarra Hospital. PARTICIPANTS: A total of 10 semi-structured interviews were conducted. RESULTS: The study reveals that psychiatrists encounter communication challenges in telephone consultations, such as the absence of visual cues, confirming patient identity, conducting comprehensive assessments and effectively communicating with younger patients who may lack developed social skills or patients with specific health conditions. Infrastructure limitations, such as outdated medical records, lack of electronic prescriptions and limited availability of child/adolescent psychiatric medications, further restrict the effectiveness of telepsychiatry consultations. In contrast, telephone appointments offer convenience and flexibility for psychiatrists, allowing them to manage non-clinical responsibilities and provide focused consultations tailored to individual needs. In addition, it benefits patients by improving appointment adherence, diminishing stigma and financial savings compared with in-person consultations. CONCLUSIONS: Tele-mental health has emerged as a promising avenue for enhancing mental healthcare services in Oman. Addressing psychiatrists' challenges is crucial to further developing and strengthening these services.

RESUMO

Economic growth has a potential impact on waste generation worldwide. Growing recognition for resources recovery from waste including production of a clean energy has led to the development of standards for, and the generation of, Solid Recovered Fuel (SRF). SRF, according to BS EN ISO 21640 is a fuel prepared from nonhazardous/treated waste to be utilized for energy recovery in incineration or co-incineration plants which meets the classification and specification. The amount of combustible fractions (i.e., plastic, textile and paper) that are present in Healthcare Waste (HCW) and Municipal Solid Waste (MSW) provides an opportunity for SRF production. HCW is defined as clinical waste generated from healthcare facilities. Limited efforts in utilizing treated HCW in production of SRF were noted, despite the fact that high content of combustible fractions, hence the novelty of this research. This research addresses the opportunities of utilizing autoclaved HCW as an alternate fuel; through a detailed chemical and physical analysis of autoclaved HCW collected from the Sultanate of Oman hospital and healthcare facilities. Furthermore, this study examines the possible uses of such materials instead of landfilling. The utilization of treated HCW as an alternative fuel is not only saving the land space, but also reduces the carbon emissions originating from landfilling. This in fact would also support the government in achieving its aspiring goal of the net zero carbon emissions by 2050 through better utilization of these materials in production of SRF as an alternative to fossil fuel combustion. The study revealed that autoclaved HCW appears to have a high quality SRF and is classified as (NCV 4, Cl 3); which complies with the potential end users' specifications. It is estimated that the combined energy output from MSW and HCW combustible fractions could cover about 12.75% of the energy requirements for Oman cement factories.Implications: The results confirm the viability of using autoclave (HCW) as an alternative fuel due to its high thermal energy content. Based on mean Net Calorific Value (NCV) of analyzed HCW that is found around 14 (MJ/Kg (ar)), and the mean Cl level (i.e., 0.814 ± 0.213% (d)); the SRF is classified as (NCV4, Cl 3). This grade is found to be well within the end users accepted range. This opens up the opportunity for creating a market demand for HCW that not only it could boost its recovery, but it could also unlock the value that can generates.

RESUMO

Marine litter and microplastic pollution in mangroves pose significant threats. This study of litter in Omani mangroves revealed an average density of 0.83 to 21.92 items/m2. Quriyat lagoon emerged as the most contaminated area, hosting 133 items/m2, while Qurum Natural Reserve lagoon showed the least contamination at 10 items/m2. Plastics constituted 73-96 % of the litter, with microplastic levels in sediment ranging from 6 to 256 pieces/kg. Al-Sawadi's lagoon had the highest microplastic abundance (27.52 ± 5.32 pieces/kg), in contrast to Al Qurum's Marine Protected Area with the lowest (0.60 ± 1.12 pieces/kg). Microplastics, categorized as fragments, pellets, and fibers, were distributed across zones 40.05 % landward, 30.97 % seaward, and 28.98 % in the middle mangrove zones. Primary plastic polymers identified were Polyethylene (PE) at 40 % and High-Density Polyethylene (HDPE) at 28 %, along with others found in specific areas. Our findings provide essential baseline data for future monitoring efforts and management strategies in Oman and other countries.

RESUMO

Anthropogenic activities lead to environmental contamination with foreign substances such as heavy metals. This work was aimed to monitor trace elements (total arsenic (As), cadmium (Cd), chrome (Cr), cobalt (Co), copper (Cu), lead (Pb), manganese (Mn), mercury (Hg), nickel (Ni), and zinc (Zn)) contamination levels (dry weight base) in three natural freshwater reservoirs of Oman including Al Khawd and Al Amarat (Muscat Governorate) and Surur area (Ad Dakhiliyah Governorate as control area) using a native benthic inland fish (Garra shamal; Cyprinidae) for the first time. The muscle and liver of a hundred and twenty G. shamal were collected to assess the degree of metal contamination. Atomic absorption spectrometry was used as an analytical technique. From the spectrum of analyzed elements, we found Zn as a major element in monitored areas. The statistically significant (P < 0.05) highest concentrations of Zn liver (0.275 ± 0.065 µg/g) were in Al Amarat compared to the other areas. The concentrations of monitored elements in the fish muscle were lower than the liver samples. Furthermore, the fish length was significantly correlated with the accumulation of Hg and Co in both muscle and liver samples. In all analyzed fish from Oman inland water, the concentrations of elements were below the permissible limits; however, additional research is needed.

RESUMO

BACKGROUND: Chronic hepatitis C (CHC) is a leading cause of cirrhosis and hepatocellular carcinoma (HCC) worldwide. This study aimed to determine rates and predictors of survival among Omani patients with CHC at a tertiary hospital in Muscat, Oman. METHODS: This ambidirectional cohort study included all CHC patients who presented to the Sultan Qaboos University Hospital between January 2009 and December 2017. Baseline demographic, clinical, laboratory, and radiological data were analyzed. Patients were followed-up until death or the endpoint of the study (April 2022) to determine survival and associations with other parameters. RESULTS: A total of 702 CHC patients were included, of which 398 (56.7%) were under 50 years of age and 477 (67.9%) were male. Overall, 180 patients (25.6%) died by the study endpoint. The mean duration of follow-up was 93.3 ± 48.0 months. The 5-year survival rate was estimated to be 80.5%, while the 10-year survival was 73%. Sustained virological response and the absence of diabetes mellitus, chronic kidney disease, HCC, or other malignancies were associated with significantly better overall survival. The 3- and 5-year survival rate of patients with hepatitis C virus (HCV)-related HCC was 46.5% and 27.6%, respectively, with a median survival of 29.5 months. Co-infection with hepatitis B was associated with poor survival among this subgroup; conversely, early HCV screening and the presence of a single HCC lesion were associated with better overall survival. CONCLUSIONS: National policies for early CHC screening and rapid treatment are needed to improve survival rates in this population.

RESUMO

Placenta accreta spectrum (PAS) comprising placenta accreta, increta, and percreta, is 1 of the leading causes of peripartum hemorrhage and accounts for up to 50% of all cesarean hysterectomies (CH). We analyzed the data of 216 parturients with PAS who underwent cesarean delivery (CD) and/or CH. Intraoperative surgical complications were noted in 215 (99.5%). The mean estimated blood loss was 2743 (1790) mL, and 105 parturients (48.6%) lost ≥2500 mL. The patients experienced high rates of severe acute maternal morbidity [162 (75%)], hysterectomy [82 (38%)], large volume blood loss, blood transfusion, peripartum anemia, and prolonged hospital stay.

RESUMO

BACKGROUND: There is increasing evidence that a companionship is an important tool for improving the quality of care provided to pregnant women during the labour and delivery process. The literature review shows very limited studies assessing the role of companions during childbirth from the companion's point of view. Many published papers studied the role and satisfaction of pregnant women but not their companions. Therefore, this study aimed to assess the role and effect of companions during childbirth in Oman. METHODS: This cross-sectional observational study was conducted at Sultan Qaboos University Hospital, Oman, between June 2022 and April 2023. Companions were interviewed face-to-face at a time convenient to them. A telephone interview was conducted with those who left the hospital early. The questionnaire comprised sociodemographic data and other sections, including the nature of the help provided by the supportive companion, their effects on the women who gave birth, and the timing of their presence during companionship. RESULTS: A total of 214 companions were included in this study with the mean age of 42.54 years. The most common relationship to the pregnant women was mothers (35.7%), followed by husbands (30.5%). The majority of companions provided support during admission (62.6%), in the immediate post-partum ward (56.5%) and during delivery (54.2%), while a minority helped from admission to discharge (22.4%). The most common type of support provided was encouraging words (89.7%) followed by transferring things (43.9%), massage (37.4%) and touch (33.6%). The majority of companions (96.7%) reported that their support helped very much, and the pregnant women felt better and calmer. CONCLUSIONS: Labouring women felt better and calmer because of the presence of companions. Companions preferred to be present in the postpartum and during labour and delivery. The majority of companions support their labouring women by encouraging wards. Companions love and encourage others to support their labouring women during their critical times.
