Physicians' knowledge and practice towards medical error reporting: a cross-sectional hospital-based study in Saudi Arabia.

Identifying reasons for under-reporting is crucial in reducing the incidence of medical errors. We studied physicians' knowledge of the occurrence, frequency and causes of medical errors and their actual practice toward reporting them. A cross-sectional, self-administered questionnaire was answered by 107 physicians at a tertiary-care hospital in Saudi Arabia. The questionnaire had 6 sections covering demographic data, knowledge, attitudes and practice towards reporting medical errors, perceived causes of and frequency of medical errors in their hospital and personal experiences of medical error reporting. Physicians tended not to report medical errors when no harm had occurred to patients. One-third of respondents feared punitive actions if they reported errors and only 56.4% felt that error reporting had led to positive changes in overall care. A majority of errors were related to late interventions and misdiagnosis. Under-reporting of medical errors was common in this hospital. Physicians did not appreciate attempts to improve the system of error reporting and a culture of blame still prevailed.

L'identification des raisons de la sous-notification est cruciale pour reduire l'incidence des erreurs medicales. Nous avons etudie les connaissances des medecins sur la survenue, la frequence et les causes des erreurs medicales ainsi que leur pratique reelle en termes de notification. Un autoquestionnaire transversal a ete rempli par 107 medecins dans un hopital de soins tertiaires en Arabie saoudite. Le questionnaire presentait six sections couvrant les donnees demographiques, les connaissances, les attitudes et les pratiques vis-a-vis de la notification des erreurs medicales, les causes percues et la frequence des erreurs medicales dans leur hopital ainsi que les experiences personnelles en matiere de notification. Les medecins avaient tendance a ne pas notifier les erreurs medicales lorsque les patients n'avaient souffert d'aucun dommage. Un tiers des repondants craignaient les actions punitives s'ils notifiaient des erreurs et seuls 56,4 % pensaient que la notification des erreurs entrainait des modifications positives pour l'ensemble des soins. Une majorite d'erreurs etait liee a des interventions tardives et des erreurs de diagnostic. La sous-notification des erreurs medicales etait frequente dans cet hopital. Les medecins ne percevaient pas positivement les tentatives d'amelioration du systeme de notification des erreurs et la culture du blame restait prevalente

Negative ethical behaviors in Saudi hospitals: How prevalent are they perceived to be? - Statement agreement study.

BACKGROUND: There is limited information about the prevalence of unethical behavior and how is perceived among health care providers. The aim of this study is to assess such behavior and how is perceived. MATERIALS AND METHODS: This is a cross-sectional study among three groups of professionals. Total participants were 370 and included medical staff, medical residents, and nurses in five medical specialties in four tertiary hospitals in Saudi Arabia (two Ministry of Health Hospitals and two military Hospitals). Participants were asked to rate their agreement with occurrence of 15 "negative" unethical behavior scenarios in their workplace. The scenarios covered areas of "respect for persons", "interprofessional relationships", and "empathy with patients". RESULTS: Majority of respondents agreed that "unethical" behavior occurred in their workplace, including confidentiality being compromised (36.3%), informed consent not taken properly (60.2%), and bad news not well-delivered (62.2%). Other significant area agreement included doctors lacking empathy (47.8%), patient autonomy not fully respected (42.5%), discrimination (41.2%), and being pressurized to write inaccurate reports (31.2%). Respondents in medicine had the lowest rate of agreement and those in psychiatry had the highest (mean of 49.8% and 82.3%, respectively). Respondents with length of employment of less than 6 years had significantly higher agreement that unethical behavior occurs compared to those with length of employment of more than 6 years. Males were more likely than females to agree that unethical behavior occurs. The biggest difference was seen in the behavior of "informed consent not properly taken" with a gender margin of 18.7% (P = 0.001). CONCLUSION: There is high prevalence of behavior that is considered unethical as perceived by various health care workers at Saudi hospitals.

Prevalence of hyponatremia among patients who used indapamide and hydrochlorothiazide: a single center retrospective study.

Hyponatremia is the most frequently encountered electrolyte abnormality among hospitalized patients and thiazide users. In this large single-center retrospective study, we aim to determine the prevalence and risk factors of hyponatremia among patients at the King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia.To the best of our knowledge, this is the first such study in Saudi Arabia. A chart review was done for the years 2011-2012 of all admitted Saudi patients at KAMC who were treated with indapamide and hydrochlorothiazide. A total of 2000 patients were included [1237 females (629 indapamide and 608 hydrochlorothiazide) and 762 males (371 indapamide and 391 hydrochlorothiazide)]. Majority of the patients had type-2 diabetes mellitus (T2DM) with an overall prevalence of 72.2%. The overall prevalence of hyponatremia, regardless of severity, in the indapamide group was 37.3% versus 38.7% in the hydrochlorothiazide group. Stratification for age revealed that older patients had relatively higher levels of sodium (Na) as compared with younger patients, and this inverse association was significant (R = - 0.123; P <0.001). Increasing age, female gender and presence of T2DM were the significant risk factors for hyponatremia, explaining the 4.7% of the variance perceived (P <0.001). Our study suggests that the prevalence of hyponatremia among Saudi thiazide users is relatively high, and more so for the elderly and for those with T2DM. Early identification of this condition is important and caution should be exercised while prescribing thiazide drugs, particularly to those who are most at risk of developing hyponatremia to prevent related complications.

Glomerulonephritis with crescents among adult Saudi patients outcome and its predictors.

The aim of this study is to investigate the clinical and pathological features and outcome of glomerulonephritis with crescents among adult patients. This is a retrospective study of all cases of crescentic GN seen over a 9-year period (2001-2010). Histological features were assessed, and renal function at baseline and end of follow-up period was recorded. Results among different etiological groups at baseline and end of follow-up period were compared. The mean age in the whole group was 35.6 years (16.2), with the lowest mean in the lupus nephritis (LN) group [27.7 years (9.9)] and the highest in the pauciimmune glomerulonephritis (PIGN) group (P = 0.001). There were 72 cases enrolled in the study. LN accounted for 49.3% of the cases, PIGN for 26.5%, other immune complex glomerulonephritis (ICGN) for 19% and post-infectious GN accounted for 6.3% The majority (85.7%) of the patients had renal impairment at presentation (mean serum creatinine levels were 247 (85) µmol/l, 412 (75) µmol/l and 230 (141) µmol/l in LN, PICN and ICGN, respectively (P = 0.05). Women accounted for 85.3, 76.5 and 36.2% of the patients in LN, PICN and ICGN, respectively (P = 0.025). By the end of the follow-up period of 26 (22.9) months, 25.8% of the patients were requiring dialysis (16.70% in the LN group, 50% in PIGN and 25% in ICGN (P = 0.05) and 21.7% had nephrotic range proteinuria (16.7, 1 and 33.3%, respectively (P = 0.4). Using logistic multivariate analysis, the only independent factors found to predict need for dialysis of prognosis were percent of sclerosed glomeruli (P = 0.05) and presence of ATN (P = 0.028). Baseline proteinuria or SCr, gender and number of glomeruli with crescents, on the other hand, did not impact prognosis. Using linear regression multivariate analysis, SCr, protein excretion and activity score at biopsy did not influence change in SCr or final SCr during the follow-up period. Using ANOVA to compare the groups of LN, PIGN and ICGN), we found significant differences only in gender between LN and ICGN (P = 0.035), in percent glomerular global sclerosis (between LN and PIGN (P = 0.007) and between LN and ICGN (P = 0.012) and in age (between LN and PIGN (P = 0.006). Almost half of our patients with CrGN were due to LN which is higher than that reported by others where PIGN was the more prevalent etiology. Patients with PICN were older and had worse prognosis. This could be explained by the higher number of globally sclerosed glomeruli in the PIGN group.

Predictors of mortality and end stage renal disease in Saudi patients with lupus nephritis.

The purpose of this study was to investigate the presentation and factors affecting outcome over a 9-year period in 99 consecutive Saudi patients with biopsy proven lupus nephritis (LN), 35.5% of whom had nephrotic range proteinuria, 46.8% had estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2) and 65.5% had histological class IV. The female:male ratio was 3.7:1. During the observation period, there were significant rises in eGFR (p = 0.005), C4 (p = 0.000) and significant decrease in 24-h urine protein (p = 0.028). No correlation was found between final eGFR and baseline 24-h protein, anti-DNA, C3 or C4. Female patients had a significantly higher rise in eGFR (p = 0.05).During follow-up (FU), 28.2% required dialysis. The survival rates at 5, 10 and 15 years were 92%, 77% and 77% respectively. Baseline C3 and C4 levels were significantly lower in the patients who died (p = 0.0001 and 0.02 respectively). Those who required dialysis were more likely to die (p < 0.000) (risk ratio = 4.46; 95% confidence interval 2.8-7.2). Hypertension at presentation was associated with lower baseline eGFR (p = 0.01) and final eGFR (p = 0.002) but did not affect the baseline proteinuria. Baseline eGFR of <60 ml/min/1.73 m(2) at presentation was associated with lower eGFR at end of FU (p = 0.000), higher activity score (p = 0.0001) and chronicity scores (p = 0.017).

Glomerulonephritis with crescents in children: etiology and predictors of renal outcome.

Objective. To investigate the clinicopathological features and outcome of glomerulonephritis with crescents among Saudi children. Method. This is a retrospective study of cases of crescentic glomerulonephritis (CrGN) seen over a 9-year period. Histological features and renal function were recorded. Results. Thirty-seven cases were enrolled. The mean percent of glomeruli with crescents was 39% (±19). Lupus nephritis (LN) was the commonest etiology (54.1%). At presentation, the serum creatinine (SCr) was 218.2 (±174.3) umol/l, and 57.1% of the cases had nephrotic range proteinuria. By the end of the observation period, SCr dropped to 81.0 (±67.7) umol/l (P = 0.001). Worsening renal function was associated with younger age (P = 0.002), non-LN etiology (P = 0.01), more crescents (P = 0.019), and ATN (P = 0.05). At the end of the followup, more patients in the LN group were dialysis-free (P = 0.017) and had improved renal function (0.01) than in the non-LN group. Using multivariate analysis, the only independent factor found to predict need for dialysis or change in SCr level was percent of globally sclerosed glomeruli (P = 0.034). Conclusion. LN is the main cause of CrGN in our cohort of children. The LN group had less globally sclerorsed glomeruli and better renal prognosis than the non-LN group.

Factors affecting hemodialysis patients' satisfaction with their dialysis therapy.

Aim. To assess the degree of satisfaction among hemodialysis patients and the factors influencing this satisfaction. Methods. Patients were recruited from 3 Saudi dialysis centers. Demographic data was collected. Using 1 to 10 Likert scale, the patients were asked to rate the overall satisfaction with, and the overall impact of, their dialysis therapy on their lives and to rate the effect of the dialysis therapy on 15 qualities of life domains. Results. 322 patients were recruited (72.6% of the total eligible patients). The mean age was 51.7 years (±15.4); 58% have been on dialysis for >3 years. The mean Charlson Comorbidity Index was 3.2 (±2), and Kt/V was 1.3 (±0.44). The mean satisfaction score was (7.41 ± 2.75) and the mean score of the impact of the dialysis on the patients' lives was 5.32 ± 2.55. Male patients reported worse effect of dialysis on family life, social life, energy, and appetite. Longer period since the commencement of dialysis was associated with adverse effect on finances and energy. Lower level of education was associated with worse dialysis effect on stress, overall health, sexual life, hobbies, and exercise ability. Conclusion. The level of satisfaction is affected by gender, duration on dialysis, educational level, and standard of care given.

Impact of recipient and donor nonimmunologic factors on the outcome of deceased donor kidney transplantation.

OBJECTIVE: To study the influence of nonimmunologic factors on the outcome of extended criteria deceased donor (DD) kidney transplants. METHOD: This is a retrospective study of DD transplantation carried out from January 1, 2003 to December 31, 2007, to investigate the impact on graft survival and function of donor renal function at retrieval, cold ischemia time (CIT), delayed graft function (DGF), acute rejection episodes (ARE), age, and weight of donors and recipients, transplant center activities, cause of donor death, donor-recipient gender pairing and size of the donating intensive care unit (ICU). RESULTS: At retrieval, the frequency of donors with a creatinine clearance <60 mL/min, using the Cockcroft-Gault formula, and age >40 years were 31.7% and 32%, respectively. CIT > 24 hours, DGF, and ARE occurred in 27.1%, 33.4%, and 16.5% of cases, respectively. The overall 1- and 5-year graft and patient survival rates were 88% and 79.8% and 96.6% and 92.3%, respectively. The graft function was inferior with occurrences of ARE (P = .0001), DGF (P = .0001), CIT > 20 hours (P = .005), nontraumatic the donor death (P = .022), and donor ICUs bed capacity <20 (P = .03). The odds ratio (OR) for graft loss with DGF, ARE, and donors right kidneys were 7.74 (95% confidence interval [CI] 6-13.4; P = .0001), 4.47 (95% CI, 2.6-7.6; P = .0001) and 1.7 (95% CI, 1-2.8; P = .045), respectively. Graft function was not influenced by donor renal function at retrieval, donor weight, or donor- recipient gender pairings. CONCLUSION: CIT and ARE had an impact on both graft survival and function. DGF and cerebrovascular accidents as the cause of donor death negatively affected graft function during follow-up. ICU center experience had a positive impact on graft survival. Patient survival was affected by recipient age >50 years and female to male donation versus other gender pairings. Neither donor age nor acute terminal rise in the donor serum creatinine affected graft function or survival, or patient mortality.

Distinguishing recurrent primary brain tumor from radiation injury: a preliminary study using a susceptibility-weighted MR imaging-guided apparent diffusion coefficient analysis strategy.

BACKGROUND AND PURPOSE: The accurate delineation of tumor recurrence presents a significant problem in neuro-oncology. Our aim was to improve the identification of brain tumor recurrence from chemoradiation injury by using CE-SWI, a technique that provides improved visualization of the heterogeneous patterns of brain tumor pathology, to guide the analysis of ADC measures within the peritumoral territory. MATERIALS AND METHODS: Seventeen patients who were being treated for high-grade glial neoplasms took part in the study. All patients presented with new enhancing lesions on follow-up CE-T1. Recurrence or chemoradiation injury was confirmed from either histologic analysis or extensive clinical follow-up. Regions of enhancement on registered CE-SWI and CE-T1 images were extracted in a semiautomated fashion and transferred to co-registered ADC maps. Significant differences in ADC measures defined within the enhancement volumes on serial MR images were analyzed by using a nonparametric Kolmogorov-Smirnov approach and correlated with clinical follow-up diagnoses. RESULTS: Analysis of the serial data revealed that patients with a diagnosis of tumor recurrence had significantly reduced ADC measures within the enhancement volume delineated on CE-SWI. In contrast, patients with SD had significantly elevated ADC within the CE-SWI enhancement volume. CONCLUSIONS: The findings of an increase in enhancement volume delineated on serial CE-SWI maps, along with a concomitant reduction in ADC within this volume for patients with recurrent tumor, provide support for such an approach to be used to assist in follow-up patient management strategies.

Usefulness of susceptibility-weighted imaging for voxel placement in MR spectroscopy.

MR spectroscopy is used to provide in vivo biochemical information about cerebral metabolites. Magnetic field homogeneity secondary to anatomic interfaces, hemorrhage, or necrosis may lead to suboptimal MR spectroscopy. Susceptibility-weighted imaging (SWI) can identify field inhomogeneity and could be used to guide MR spectroscopy voxel placement, leading to higher-quality MR spectroscopy examinations.
