Medical malpractice in Oman: A 12-year retrospective record review.

BACKGROUND: There is a paucity of studies documenting medical malpractice litigation in countries of the Arabian Gulf, such as Oman. OBJECTIVES: To describe the characteristics of malpractice claims, the outcomes decided by the medical liability committee, and predictors of medical errors. METHODS: This is a retrospective observational study that reviewed medical malpractice cases registered in Oman over a 12-year period (2010-2021) with the medical liability committee, known as the Higher Medical Committee (HMC). Descriptive and inferential statistical techniques, including multiple logistic regression techniques, were used for data analysis. RESULTS: Between 2010 and 2021, the HMC registered 1284 medical malpractice cases, out of which 1048 were fully investigated. The number of registered cases increased during this period. These cases included those raised by Omani nationals and expatriates, with a majority (86%) raised by Omani complainants. Two-thirds (67%) of the cases involved adult complainants aged 18-60 years. About 43% of the cases were from the urban Muscat region, and 68% were related to public hospitals. The most common specialties involved were obstetrics and gynecology (20.1%), internal medicine (19.7%), surgery (17.6%) and orthopedics (13.8%). Half (51%) of the appeals or grievances were dismissed because they were not preceded by medical negligence or malpractice. The average waiting time to initiate the investigation was 10 months. Errors were more common among non-Omani complainants and cases related to private hospitals. Significant predictors of errors included nationality (i.e. Omani vs. non-Omani), the referring institution, the medical specialty and the type of health institution involved, and the waiting time to initiate the investigation. CONCLUSION: To date, the number of cases of medical malpractice in Oman is lower compared to international trends, although there has been an upsurge in recent years. More research using a more robust methodology is warranted to contextualise the factors that contribute to this upward trend, as well as the preponderance in urban settings and among certain demographic populations.

Assessment of Total Cardiovascular Risk Using WHO/ISH Risk Prediction Chart Among Adults in Oman: A Nationally Representative Survey.

Objectives: Cardiovascular diseases (CVDs) are the major cause of morbidity and mortality globally and in Oman. Stratifying the population under different risk levels based on the total CVD risk approach using the World Health Organization/International Society of Hypertension (WHO/ISH) risk prediction chart would be more effective in primary prevention of CVD to prioritize and utilize valuable resources. Hence, this study aimed to assess the total 10-year CVD risk among adults in Oman and to ascertain the proportion of the population in need of pharmacotherapy. Methods: We used the data from the 2017 national community-based STEPS survey conducted among men and women in Oman aged 40-80 years. Ten-year total cardiovascular risk was measured using the WHO/ISH risk prediction chart for Eastern Mediterranean Sub-Region B. Independent t-test and Chi-square were used to test significance. Results: There were 2510 participants in the study. Their mean age was 51.5±10.1 years and 51.3% were male. The prevalence of low, moderate, and high CVD risk was 68.0%, 19.1%, and 12.9%, respectively, as benchmarked by the WHO/ISH chart. Immediate pharmacotherapy was needed by 30.3% of participants. Factors significantly associated with elevated CVD risk were the participant's age (p < 0.001), education level (p < 0.001), and employment status (p < 0.001). Conclusions: A substantial fraction of the population in Oman are at moderate or high CVD risk. Prompt pharmacological interventions are warranted for at least one in every five individuals in conjunction with lifestyle changes.

Prevalence of risk factors of non-communicable diseases in the Sultanate of Oman: STEPS survey 2017.

BACKGROUND: Non-communicable diseases (NCD) represent a major public health issue and currently cause 185.75 deaths per 100,000 population in Oman. Hence, there is a need for comprehensive, up-to-date and internationally comparable data on NCD risk factors in order to evaluate the effectiveness of ongoing public health policies and to develop further NCD prevention and control interventions. The aim of the study was to provide evidence-based, up-to-date, extensive, and reliable baseline data on the behavioural and biological risk factors of NCDs in the Sultanate of Oman. METHODS: A cross-sectional, prospective, observational community-based survey designed to be nationally representative of the Sultanate of Oman was conducted based on the WHO STEPwise approach to Surveillance (STEPS). Multi-stage stratified random sampling according to geographical distribution selected a total of 9053 households (Omani nationals and non-Omani residents). Cluster sampling was used to randomly select equal clusters from each governorate. 823 households were randomly selected from the list of all households in all selected clusters from each governorate and one eligible adult selected from each household randomly accounting for 6582 consenting participants. The survey used demographic and behavioural information questionnaires along with physical and biochemical measurements among adults aged 18 years and above. RESULTS: The prevalence of behavioural risk factors such as tobacco use was 9%, alcohol consumption was 2%, insufficient fruit or vegetable intake was 61%, and insufficient physical activity was 39%. The prevalence of biological risk factors such as overweight and obesity was 66%, raised blood pressure was 33%, raised blood glucose was 16%, and raised blood cholesterol was 36%. The prevalence of multiple risk factors was also determined and 95% of the population were found to have more than one risk factor. Three or more risk factors were found among 33% of population aged 18 years and above and 45% of the population aged 45 years and above. CONCLUSION: A high prevalence of various NCD risk factors was found which needs to be addressed through health promotion, education, and policy. The findings are important to support the formulation and implementation of NCD-related policies and action plans that improve health status and prevent mortality due to NCDs in Oman.

Prevalence and risk factors of diabetes in a large community-based study in the Sultanate of Oman: STEPS survey 2017.

BACKGROUND: Type 2 diabetes in the Gulf Cooperation Council countries, including Oman, is currently the fastest growing health crisis and is a significant cause of premature mortality and disability. There is currently insufficient up-to-date information available on prevalence of type 2 diabetes. This study aimed to assess the latest prevalence of type 2 diabetes mellitus and its associated demographic, behavioural, and clinical risk factors. METHODS: Using the WHO STEPwise approach to chronic disease surveillance, a nationally representative population-based survey was conducted from January to April 2017 of adults aged 18 years and above. A multi-stage, stratified, geographically clustered random sampling surveyed 9053 households including Omani nationals and non-Omani residents. Univariate and multiple logistic regression analysis was performed to determine the predictors of diabetes. RESULTS: Overall prevalence of diabetes among the population was 15.7% (95% CI: 14.0-17.5%) whereas prevalence of prediabetes was 11.8% (95% CI: 11.4-12.2%). Age, educational level, raised blood pressure, family history of diabetes, abnormal waist-to-hip ratio, and hypertriglyceridemia were found to be significantly associated with diabetes mellitus. Of the cases of diabetes mellitus, 17% were newly diagnosed and 13.2% were on medication and had an uncontrolled glucose level while 55.5% were not taking medication (although diagnosed) and had an uncontrolled blood glucose level. CONCLUSIONS: The present study provides reliable information regarding the high prevalence of diabetes mellitus among the adult population in Oman with urgent attention needed to address this significant burden on the health system. The high proportion of uncontrolled cases warrants further research, awareness programmes, and community interventions.

National survey to estimate sodium and potassium intake and knowledge attitudes and behaviours towards salt consumption of adults in the Sultanate of Oman.

OBJECTIVES: To estimate population sodium and potassium intakes and explore knowledge, attitudes and behaviour (KAB) towards the use of salt in adults in the Sultanate of Oman. DESIGN: National cross-sectional population-based survey. SETTING: Proportional random samples, representative of Omani adults (18 years or older), were obtained from all governorates of the Sultanate of Oman. PARTICIPANTS: Five hundred and sixty-nine (193 men, 376 women; 18 years or older) were included in the analysis (response rate 57%). Mean age was 39.4 years (SD 13.1). Participants attended a screening including demographic, anthropometric and physical measurements. PRIMARY AND SECONDARY OUTCOME MEASURES: We assessed dietary sodium, potassium and creatinine by 24-hour urinary sodium (UNa), potassium (UK) and creatinine (UCr) excretions. We collected KAB by a questionnaire on an electronic tablet. RESULTS: Mean UNa was 144.3 (78.8) mmol/day, equivalent to 9.0 g of salt/day and potassium excretion 52.6 (32.6) mmol/day, equivalent to 2.36 g/day, after adjusting for non-urinary losses. Men ate significantly more sodium and potassium than women. Only 22% of the sample had a salt intake below the WHO recommended target of 5 g/day and less than 10% met WHO targets for potassium excretion (>90 mmol/day). While 89.1% of those interviewed knew that consuming too much salt could cause serious health problems and only 6.9% felt they were using too much added salt, one in two participants used always or often salt, salty seasonings or salty sauces in cooking or when preparing food at home. CONCLUSIONS: In the Sultanate of Oman, salt consumption is higher and potassium consumption lower than recommended by WHO, both in men and in women. The present data provide, for the first time, evidence to support a national programme of population salt reduction to prevent the increasing burden of cardiovascular disease in the area.
