Effect of electronic prescription system modifications on reducing prescribing errors in a military hospital.

The implementation of electronic prescription systems has become a crucial advancement in healthcare, intending to enhance the precision, safety, and effectiveness of the prescription process. Electronic prescription systems provide many solutions to reduce prescribing errors by allowing system modifications that streamline the prescribing process to improve communication between healthcare practitioners. In this study, we aimed to explore the effect of electronic prescription system modification on minimising prescribing errors. This retrospective quantitative study assessed the effects of electronic prescribing system modification in a tertiary military centre in Saudi Arabia, specifically focusing on decreasing prescribing errors in different hospital departments. Collected data include all prescribing errors that occurred in the inpatient setting during the study period, while exclude prescribing errors for outpatient settings as they have different e-prescribing system. A total of 29,554 patient admissions were analysed to compare the frequency of prescribing errors before and after the introduction of electronic prescriptions modification. The findings from this study indicate a total reduction in prescribing errors after electronic prescription modifications from 1.43% to 0.51% (p-value < 0.001) across all departments, which is highly significant. Furthermore, there was a significant reduction of 49.8% in the overall prescribing error rate. The overall reduction in total errors occurrences after implementing e-prescription modifications suggests a systemic improvement, even if individual departments showed mixed results. This study emphasises the advantages of electronic prescribing system modification in improving patient safety and optimising healthcare operations. However, the variance in results across departments highlights the need for tailored modifications and continuous system optimisation. By addressing the specific needs of each department, hospitals can maximise the benefits of e-prescribing system and achieve more consistent reductions in prescribing errors in clinical practice.

The prevalence and etiology of infertility in a tertiary specialist hospital in the Gambia

Background: Infertility is a public health problem that has received little or no attention in most sub-Saharan Africa, especially in the Gambia. The prevalence of infertility in the Gambia is increasing from 9.0% in 1998 to 14.3% in 2017. Tubal factor was the predominant leading cause for decades, but recent reviews suggest that male factor is driving the epidermic of infertility worldwide. Therefore, the aim of this study was to determine the prevalence and etiological factors of infertility in our practice. Methodology: The design was a retrospective quantitative study. Data collection tool was developed and variables were retrieved from case notes between August 2022 to March 2023 at a specialist hospital in the Gambia. The data were entered into a computer database and analyzed using descriptive statistics. Results: Total number of women in the reproductive age of 15–49 years that attended gynecology clinic was 1475. Two hundred eighty-five couples (285) had infertility. The prevalence of infertility is 19.3% ~1:5 couples. The causes showed male factor 69 (45.4%), ovulation disorder 34 (22.4%), tubal factor 20 (13.2%), uterine factor 8 (5.3%), and unexplained 21(13.8%). Ovarian factors showed age-related poor ovarian reserve. Overall, male factor infertility was 53%, and female factor infertility was 47%. Conclusions: The prevalence of infertility is increasing and male factor is 3-folds and 2-folds higher than tubal and ovarian factors, respectively. The study observed increasing desire of fertility among female in advanced age. Universal access to assisted reproductive technology is essential.

Clinical audit of cases and outcomes of patients admitted to the intensive care unit at Kamuzu Central Hospital, Lilongwe, Malawi

In 2016, a new, improved and modern intensive care unit was constructed at Kamuzu Central Hospital in Lilongwe, Malawi. Having been operational for about 4 years, there has not been a systematic audit to gauge its performance. Therefore, this quantitative retrospective cohort study aimed at investigating the performance of the intensive care unit at Kamuzu Central Hospital in Lilongwe, Malawi. We analysed the patterns of admission through 250 clinical cases and their respective outcomes spanning from 1st January 2019 to 31st December 2019 using STATA. Descriptive and inferential statistics were computed. We also had a follow-up discussion with the Head of the unit to better understand the unit’s functioning. Out of the 250 admissions, we evaluated 249 case files. About 30.8% of all patients were referred from the main operating theatre, and 20.7% from the casualty (emergency medicine). Head injury (26.7%) and peritonitis (15.7%) were the commonest causes of admission. The overall mortality was 52.2% with more females (57.5%) dying than males (47.9%). Head injury and peritonitis had the highest contribution to the mortality accounting for 25.3% and 16.9% of all deaths respectively. In conclusion, despite the new unit registering an improved performance compared to the old unit’s 2012 mortality of 60.9%, the current mortality rate of 52.2% generally reflects a suboptimal performance. The intensive care unit is still grappling with a number of challenges that need immediate attention including few working beds, shortage of critical care specialists and nursing staff and lack of standard admission criteria.

Gender and child feeding practices in Belize- a trend analysis

The study aimed to determine the trend and gender differences in child feeding practices in Belize based on consecutive multiple indicator cluster surveys (MICS) using a retrospective quantitative study. The secondary analysis of the last consecutive MICS data from 2006, 2011 and 2015-16 was done using SPSS software version 23. Association between gender and feeding practices was determined by bivariate analysis using chi-square test and p value &lt; 0.05 was considered statistically significant. There was increased gender differentials in optimal feeding practices in children over the study period. The inequalities between male and female increased over the study period for most of the feeding practices except for exclusive breastfeeding where the gender inequality diminished. The exclusive breastfeeding rate among female children was higher than among male children in the three surveys but significant only in 2006 and 2011 surveys, p&lt;0.05. More female children were timely initiated on complementary feeding compared to male children in the three surveys and was found to be significant in 2006 and 2015 surveys, p&lt;0.05. Minimal meal frequency and minimal dietary diversity was higher among female than among male but there was no significant difference(p&gt;0.05). The study shows evidence of gender differential in feeding practices. There is need to improve gender sensitization in terms of feeding practices within the households; develop and implement culturally appropriate gender sensitive guidance and approaches on optimum infant and young child feeding practices in the country.

Demographic and Clinical Characteristics Predicting Missed Clinic Visits among Patients Living with HIV on Antiretroviral Treatment in Kinshasa and Haut-Katanga Provinces of the Democratic Republic of Congo.

Patients living with HIV (PLHIV) often face challenges that contribute to missed clinical care which can impact their health outcomes. This retrospective quantitative study comprised 5338 adults living with HIV who received antiretroviral treatment (ART) for 12 months, from July 2018 to June 2019 in Kinshasa and Haut-Katanga provinces of the Democratic Republic of Congo. Descriptive statistics were computed to show the level of missed appointments for ART. Multivariable associations of clinical and sociodemographic factors with a tendency to miss scheduled visits after adjusting for the covariates were examined using multivariable logistic regression analysis. Six percent of PLHIV experienced at least one missed visit while 94% did not miss any visits. A small proportion (20%) of PLHIV had a viral load ≥1000 copies/mL. PLHIV receiving ART from urban clinics showed significantly higher odds of missed visits compared to those from rural areas (AOR = 4.18, 95% CI [1.84-9.511]; p < 0.0001). Similarly, patients from semi-rural/semi-urban clinics showed significantly higher odds of missed visits compared to those from rural areas. (AOR = 2.57, 95% CI [1.08-6.141]; p = 0.03). Additionally, older PLHIV (18-34 years old) demonstrated increased odds of missed visits (AOR= 1.71, 95% CI [1.0078-2.697]; p = 0.02) compared to those under 18 years old. The findings from this study strongly suggest that there is a significant association between certain demographic factors, such as age and rurality-urbanicity, and missed visits. The study findings have implications for policy and interventions targeting PLHIV at higher risk of missed visits.

Radiographic Alignment Parameters for Lumbosacral Reconstruction in Patients With Altered S1 Morphology.

Retrospective quantitative analysis study. Pelvic incidence has been established as central radiographic marker which determines patient-specific correction goals during surgery for adult spinal deformity. In cases with sacral doming or sacral osteotomy where the PI cannot be calculated, reliable radiographic parameters need to be established to determine surgical goals. We aim to determine multiple radiographic parameters and formulas that can be utilized when the S1 superior endplate is obscured. Retrospective analysis was performed on 68 healthy volunteers without prior spine surgery with full-length radiographs. Pelvic incidence, sacral slope, and pelvic tilt were calculated for each patient. Additional measurements such as L4, L5, and S2 incidence, tilt, and slope were collected. A new radiographic parameter defined as the L4-Sciatic notch angle was measured. Regression analysis was performed on each value to determine its relationship with S1 based incidence, tilt, and slope. Mean values for L5 incidence, L4 incidence, and L4 sciatic notch angle were 21.8° ± 8.9, 4.4° ± 8.1, and 44.4° ± 12, respectively. The linear regression analysis produced the following formulas which can be utilized to determine deformity correction goals when pelvic incidence can be calculated pre-operatively: L5i = .65*S1i-11.4, L4i = .44*S1i-18.6, and L4SNA = -.34*S1i + 66.5. In settings where pelvic incidence cannot be calculated, the following formulas can be utilized: L5i = .66*S2i-32.3 and L4SNA = -.02*S2i2 + 1.1*S2i + 63.5. P-values for all regression analyses were <.001. This study provides target radiographic alignment values that can be utilized for patients with either pre-operative altered S1 endplates or in cases with intraoperative alteration of S1 (sacral osteotomy).

Self-reported health related quality of life in children and adolescents with an eating disorder

BackgroundEating disorders in children and adolescents can have serious medical and psychological consequences. The objective of this retrospective quantitative study is to gain insight in self-reported Health Related Quality of Life (HRQoL) of children and adolescents with a DSM-5 diagnosis of an eating disorder.MethodCollect and analyse data of patients aged 8–18 years, receiving treatment for an eating disorder. At the start and end of treatment patients completed the KIDSCREEN-52, a questionnaire measuring HRQoL.ResultsData of 140 patients were analysed. Children diagnosed with Anorexia Nervosa, Bulimia Nervosa, and Other Specified Feeding or Eating Disorder all had lower HRQoL on multiple dimensions at the start of treatment, there is no statistically significant difference between these groups. In contrast, patients with Avoidant Restrictive Food Intake Disorder only had lower HRQoL for the dimension Physical Well-Being. HRQoL showed a significant improvement in many dimensions between start and end of treatment, but did not normalize compared to normative reference values of Dutch children.ConclusionThe current study showed that self-reported HRQoL is low in children with eating disorders, both at the beginning but also at the end of treatment. This confirms the importance of continuing to invest in the various HRQoL domains.

Training physiotherapy students in basic wheelchair provision. Experiences at two universities in Colombia

Wheelchair provision training is essential to overcome barriers related to the lack of knowledge of health professionals on this topic. Appropriate knowledge of the service provision process may lead to higher quality service and products, and thus be more likely to help people with mobility impairments achieve the fundamental human right of personal mobility. This study aimed to describe a training intervention for two groups of future physiotherapists in Colombia, assess cohort differences in performance on a knowledge test, and explore their post-training perceptions. A quantitative retrospective study with a historical, descriptive-comparative design was conducted. 525 sixth-semester participants completed the International Society of Wheelchair Professionals Wheelchair Service Provision – Basic Test online in Spanish after curriculum modifications were implemented. The test assesses knowledge in seven domains: Assessment; Prescription; Products; Fitting; User training; Follow-up, maintenance, and repairs; and Process. The training intervention was successfully implemented with Physiotherapy students from two institutions, resulting in a 57% increase in test approval rates. Participants demonstrated increased knowledge, satisfaction with the course content, and application of learning to their current work. These results suggest implications for what pedagogical approach to employ, when curricular change may be warranted, and specific considerations for the Colombian context. Furthermore, identifying the minimal knowledge basis for undergraduate programs and facilitating its dissemination can support interprofessional education and enhance professionals’ capacity to support wheelchair provision services.

Sim-Based Home Tracheostomy Care: A Mixed Methods Study on Outcomes and Parental Preparedness.

To assess effects of a Simulation-Based Discharge Education Program (SDP) on long-term caregiver-reported satisfaction and to compare clinical outcomes for children with new tracheostomies whose caregivers completed SDP versus controls. The study employed a mixed methods approach: (1) a qualitative analysis of feedback from caregivers who previously completed SDP, and (2) a quantitative retrospective case-control study comparing outcomes between children with new tracheostomies whose caregivers completed SDP versus controls, matched on discharge disposition and age. The primary outcome was emergency department visits for tracheostomy-related issues within 1 year of discharge. Feedback from 18 interviews was coded into 5 themes: knowledge acquisition, active learning, comfort and preparedness, home application of skills, and overall assessment. Caregivers of 27 children (median age 26 months [interquartile range (IQR) 5.5 months-11 years]) underwent SDP training. Clinical outcomes of these children were compared with 27 matched children in the non-SDP group (median age 16 months [IQR 3.5 months-10 years]). There was no significant difference in ED visits for tracheostomy-related complications within 1 year of discharge between the SDP group and non-SDP group (2 [IQR 0-2] vs 1 [IQR 0-2], P = .2). Caregivers reported overwhelmingly positive experiences with SDP that persisted even 4 years after training. Caregiver participation in SDP did not yield a significant difference in ED visits within 1 year of discharge for tracheostomy-related complications compared with control counterparts. Future steps will identify more effective methods for comparing and analyzing clinical outcomes to further validate impacts of simulation-based programs.

Impact of the Covid-19 pandemic on Suicidal Behaviour in Copenhagen

IntroductionDuring the Covid-19 pandemic, multiple concerns were expressed about the inadequacy and unavailability of mental health services. This study aims to assess the impact of the Covid-19 pandemic on the prevalence of suicidal behaviour in Copenhagen. MethodsThis exploratory retrospective quantitative study was conducted based on annual register-based electronic health records of the Emergency Medical Services Copenhagen from 2015 to 2021. It focused on calls related to suicidal behaviour entering the Emergency Medical Dispatch Centre 112 and the medical helpline 1813. The calls were identified based on the search of the Danish and English words for suicide in the medical records. The primary outcome focused on the number of suicidal calls registered in the EMS records prior to the Covid-19 outbreak as compared to numbers during the pandemic. ResultsThe study analysed 8026 recorded suicide-related calls from March 2015 to December 2021. The number of suicidal behaviours increased by 9%. During the Covid-19 years, there was a decrease of 11% in suicidal behaviour. This pattern could be observed in all age groups. However, suicidal behaviour increased by 4% from 104 (2019) to 119 and 118 (2020 and 2021, respectively) among adolescents aged 11–18 years. The prevalence of suicidal behaviour was constantly higher among females compared to males. ConclusionWhile suicidal behaviour increased, the Covid-19 pandemic has been linked to a decline in suicidal behaviour. Adolescents and females seem to be more prone to suicidal behaviour during times of crisis compared to other age groups and males.

Evaluating aortomesenteric parameters in a tertiary center of Nepal for superior mesenteric artery syndrome diagnosis and risk factors: cross-sectional study.

This study examines aortomesenteric angle (AMA) and distance (AMD), which are critical in superior mesenteric artery (SMA) syndrome. Addressing the scarcity of SMA cases, the research explores potential links with lower BMI and aims to establish normative data for diagnostic and predictive purposes, using contrast-enhanced computed tomography (CT) scans across various BMI and sex categories. A retrospective quantitative cross-sectional study was conducted on 189 patients undergoing abdominal contrast-enhanced CT scans between December 2019 and December 2020. Ethical clearance was obtained, and participants provided informed consent. Exclusion criteria targeted specific medical histories. Patient demographics, BMI categories, and imaging data were recorded. Helical 128-slice CT scans were employed, with sagittal-oblique multiplanar reconstructions for parameter assessments. Statistical analysis utilized SPSS 26.0, including Pearson correlation coefficients and mean calculations. The study reveals a mean AMA of 54.07°±8.53° and a mean distance of 16.25±3.44 mm. Elevated BMI is found to positively correlate with AMA and distance, indicating that higher BMI values may augment these parameters, with an additional positive correlation observed between AMA and distance. No significant correlations are found with patient age or sex. The study concludes that decreased BMI may pose a potential risk for SMA syndrome, as evidenced by the observed correlations with aortomesenteric parameters. Understanding these normal values in the Nepalese population is critical for accurate diagnoses and predictions using CT scans. The research highlights the impact of demographic factors on these parameters and emphasizes their significance in clinical assessments related to SMA syndrome.

Survival rate of cervical cancer: a five year review at a Major Teaching Hospital in Ghana, West Africa.

Cervical cancer (CC) is one of the leading causes of cancer-related deaths among females in Ghana. Despite the magnitude of the public health challenge posed by CC in Ghana, survival data as well as reported incidence and mortality rates are primarily based on studies conducted in the capital city of the country. Even though age at diagnosis is known to affect the overall survival of CC patients, the role of this factor in the prognosis of CC patients in Ghana has not been sufficiently explored. The aim of this study was to determine the 5-year survival rate of Ghanaian woman treated for CC at a large tertiary healthcare facility in Ghana. This research was a single-institution-based quantitative retrospective cohort study conducted among patients with histopathologically confirmed CC. Clinical and socio-demographic data were retrieved from patients' medical records. Data analysis was done using the Statistical Package for the Social Sciences software version 23. Kaplan Meier curves were used to present the survival rates and median survival time. The peak age at diagnosis was between 45 and 80 years with the modal age group of patients between 75 and 80 years. The mean age at diagnosis was 63.3 ± 15.7 years ranging from 27 to 104 years. The overall survival rates at 1, 3 and 5 years were 76.5%, 51.5% and 32.4%, respectively. The median survival time was 65.8 months. Age < 50 years was associated with higher survival estimates than age >50 years. The 5-year overall survival rate of CC patients reported in this study (32.4%) is relatively low compared with countries in the developed world but like previous reports at other healthcare facilities in Ghana as well as in other underdeveloped countries.

Outcomes of traumatic brain injury patients in an adult intensive care unit of a South African regional hospital, without on-site neurosurgical service: A retrospective quantitative study on the neurological improvement at discharge.

Traumatic brain injury (TBI) is a major cause of mortality and disability. The South African (SA) province of Kwazulu-Natal faces challenges in providing appropriate care for TBI patients owing to limited resources and delayed access to healthcare services. We aimed to assess the outcomes of patients with TBI who were treated at a hospital without a neurosurgical unit (NSU). The primary objective was to compare the Glasgow Coma Scale (GCS) scores at admission and discharge from the intensive care unit (ICU) for patients with TBI receiving neuroprotection. Secondary objectives included analysing demographics and identifying predictive factors associated with GCS score improvement. This retrospective study analysed data from the already established ICU Integrated Critical Care Electronic Database. Data on patient demographics, mechanisms of injury and GCS scores were collected and analysed. The analysis included 95 TBI patients, most of whom were young males. Interpersonal violence and transport-related trauma were the main causes of injury among patients. Approximately 63% of patients had a GCS score improvement >1 upon discharge from the ICU. Patients who received >12 hours of neuroprotection in the emergency department had significantly lower rates of improvement. Sixty-three percent of TBI patients had improved GCS scores by >1 on discharge from the ICU, but outcomes varied. Delayed ICU admission from the emergency department of >12 hours might contribute to worse outcomes. Timely neuroprotection, improved access to neurosurgical care and better understanding of the factors affecting outcomes are needed. This study explores the outcomes of patients with TBI admitted to a non-neurosurgical ICU. Factors contributing to a worse outcome are identified, highlighting the need for adequate numbers of ICU beds and prompt admission from the emergency department.

Retrospective comparison between MRI examinations during radiographer-administered intranasal sedation or general anesthesia

IntroductionIn order for young children to be able to undergo a Magnetic Resonance Imaging (MRI) examination, general anesthesia is often required. The aim of this study was to compare the image quality, times, and costs of the examinations of infant brains performed with MRI either during sedation with dexmedetomidine administered by radiographers or anesthesia with propofol administered by anesthesia staff. MethodsThis study was a quantitative retrospective study of 27 consecutive standard brain examinations performed under sedation or anesthesia, involving 15 children under sedation and 12 under anesthesia. The age of the children was from 0.5 to five years old. The image quality was evaluated by three radiologists experienced in pediatric MRI examinations. Information such as examination time and the expense of the examination was also collected. ResultsThere was no statistically significant difference in the general image quality, but one image series was assessed to have significantly better image quality under sedation than under anesthesia, but all images had very high quality. However, it emerged that children under anesthesia were at the hospital on average 55 min longer and the scanner room was occupied 20 min longer on average. The anesthesia examinations were three times more expensive. ConclusionThis study demonstrated equivalent image quality between sedation and anesthesia. In addition, sedation was less time-consuming and had a lower price, partly because no extra anesthetic staff were required. The use of intranasal sedation offers a possibility to expand the competence area for radiographers. Implications for practiceIf radiographers learn to perform intranasal sedation, examinations can be performed in less time, at a third of the staff costs while maintaining image quality.

Factors that can affect students' wellbeing – A quantitative retrospective study

In Sweden, the role of the school nurse is to promote students' health and wellbeing and also to prevent illness. Wellbeing can involve creating good relationships but also includes feelings of participation and a meaningful existence. During a health dialogue the school nurse can discover students who experience mental illness, and factors that can affect students' wellbeing. The purpose of the study was to investigate factors that may affect students' wellbeing. A quantitative method with a retrospective longitudinal approach was applied. The study was conducted using collected data based on health questions posed to students in the first year of high school's health visit during the 2013/14–2018/19 school years. The results show differences between girls' and boys' wellbeing based on their answers to health issues. Factors that may affect students' wellbeing can pose a risk of mental illness. Mental illness is increasing in students and the increased demands at school may be the cause.

The use of the DOS and Delirium Prevalence: a quantitative longitudinal study at a Swiss-German central hospital

The use of the DOS and Delirium Prevalence: a quantitative longitudinal study at a Swiss-German central hospital Abstract: Background: With a prevalence of 12-64%, delirium is a common complication in acute care, associated with negative outcomes such as increased mortality and prolonged length of stay. Many hospitals have guidelines to improve the delirium management. The Delirium Observation Screening Scale (DOS) Score is collected in the study hospital from all patients ≥ 70 years at each shift for at least 3 days. Delirium is diagnosed by a physician and coded according to ICD-10. Purpose: Evaluation of the delirium screening with the DOS according to internal guideline in terms of number of DOS assessments performed, prevalence of delirium (DOS score ≥ 3 points, CD-10 code delirium). Method: This retrospective quantitative single-centre longitudinal study used 2017 and 2018 data of 10046 cases. Statistical analysis methods were used to analyse prevalence of delirium and subgroup comparisons. Results: At least one DOS score was documented in 92% of cases aged ≥ 70-years (n = 5038). DOS implementation varied between 60% in the early, 49% in the late and 38% in the night shift. The prevalence of delirium was 12% according to DOS score ≥ 3 and 4% according to physician diagnosis of a delirium. Cases with a DOS score ≥ 3 were significantly older, more often female, had more comorbidities and were depressed. Conclusions: DOS is performed in most patients when indicated. The DOS implementation frequency varied depending on the shift.
