Inappropriate laboratory test utilization in outpatient tertiary care: Implications for value-based healthcare.

OBJECTIVES: To assess the rate of inappropriate repetition of laboratory testing and estimate the cost of such testing for thyroid stimulating hormone (TSH), total cholesterol, vitamin D, and vitamin B12 tests. METHODS: A retrospective cohort study was carried out in the Family Medicine and Polyclinic Department at King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia. Clinical and laboratory data were collected between 2018-2021 for the 4 laboratory tests. The inappropriate repetition of tests was defined according to international guidelines and the costs were calculated using the hospital prices. RESULTS: A total of 109,929 laboratory tests carried out on 23,280 patients were included in this study. The percentage of inappropriate tests, as per the study criteria, was estimated to be 6.1% of all repeated tests. Additionally, the estimated total cost wasted amounted to 2,364,410 Saudi Riyals. Age exhibited a weak positive correlation with the total number of inappropriate tests (r=0.196, p=0.001). Furthermore, significant differences were observed in the medians of the total number of inappropriate tests among genders and nationalities (p<0.001). CONCLUSION: The study identified significantly high rates of inadequate repetitions of frequently requested laboratory tests. Urgent action is therefore crucial to overcoming such an issue.

The Impact of Continuity of Care on Health Indicators in Patients With Type 2 Diabetes Mellitus in Family Medicine Clinics in Riyadh.

BACKGROUND: Diabetes Mellitus Type 2 (DM2) is highly prevalent in Saudi Arabia, with many experiencing complications due to the disease. Family medicine physicians are usually the primary care providers responsible for the medical management of type 2 diabetes mellitus patients. Microvascular and macrovascular complications can occur if type 2 diabetes mellitus is poorly managed. Effective management of health indicators in patients with DM2 relating to glycated hemoglobin (HbA1c), low density lipoprotein cholesterol, blood pressure, and tobacco use is an essential part of medical care to prevent complications. Due to the projected increase in the number of patients with DM2, there is huge concern surrounding the management of this chronic illness that requires review. This study aims to evaluate the impact of continuity of care on health indicators among family medicine patients diagnosed with diabetes mellitus type 2 and to analyze the effect of continuity of care regarding the completion of age-appropriate preventive health screenings. METHODS:  This is a retrospective cohort study. Data collected from electronic medical records of patients 40-75 years of age that received care at the Family Medicine clinics that were diagnosed with type 2 diabetes mellitus with ≥4 clinic visits from January 1, 2017, to June 30, 2020, at King Faisal Specialist Hospital & Research Centre in Riyadh, Saudi Arabia. Data collected included demographic data, body mass index, smoking status, blood pressure, past medical history, preventive health screening completed, and laboratory results, including HbA1c and lipid profile. The continuity of care index and usual provider continuity score indices were calculated for the analysis to measure continuity of care. RESULTS:  Three hundred and fifty-two patients were included in the study. Most of the patients were Saudi (74.15%), female (51.99%), and married (82.67%). In addition, 90.34% accounted for a high usual provider continuity of care score (UPCS), and 64.20% of the patients had a high continuity of care index (COCi). Younger age groups were significantly more prevalent in the high UPCS group (p=0.037). Additionally, patients of non-Saudi nationalities constituted a significantly larger proportion of the high UPCS group. Single patients showed high UPCS. Comorbidities were not different between the groups, except inflammatory joint disease, which was more common in the low COCi group. Preventative screening measures were also not different between the groups; however, the type of colon cancer screening differed, where patients with high COCi more frequently underwent colonoscopies (13.3% vs. 4.4%, p=0.015) instead of fecal occult blood tests. CONCLUSION:  For the first time, we report the implications of the continuity of care for DM2 patients in Saudi Arabia and the Middle East. Continuity of care did not result in the improvement of health indicators or in the completion of preventive health screenings in diabetic patients. Further studies are needed in the region to confirm our findings and assess the association between continuity of care and patient health indicators impact.

Risk factors for carpal tunnel syndrome in patients attending the primary care center of a tertiary hospital in Riyadh, Saudi Arabia: A case-control study.

BACKGROUND: Carpal tunnel syndrome (CTS), the most common entrapment neuropathy in the upper extremity, is known to be a multi-factorial disease that raises medical and nonmedical risk factors. The aim of the current study was to determine the risk factors of CTS in patients attending the primary care center at a tertiary hospital. MATERIALS AND METHODS: A case-control study was conducted by reviewing all medical records of patients above the age of 18 years old diagnosed with CTS from 2015 to 2021. The selected cases were evaluated by physical examination and confirmed by a nerve conduction study. Cases and controls were matched by age, gender, and nationality, with a case-to-control ratio of 1:2. Odds ratios were calculated for association between carpel tunnel syndrome and various factors and Chi-sqauare test determined statistical significance. Multiple logistic regression was performed to adjust for confounding. RESULTS: The study recruited 144 cases with a mean age of 53.38 ± 12.20 years and 288 controls with a mean age of 53.80 ± 12.27 years. The majority of subjects were female (84.7%) and of Saudi nationality (68.3%). There was a significant difference in body mass index, employment status, number of years of employment, occupation, mean systolic blood pressure, mean low-density lipoprotein cholesterol level, and mean blood urea level between cases and controls (P < 0.05). Laboratory tests that were found to be significantly associated with CTS in univariate analysis were thyroid-stimulating hormone (crude odds ratio [COR] = 0.828) and urea level (COR = 0.802). In fully adjusted analyses, obesity (adjusted odds ratio [AOR] =3.080), chronic kidney disease (AOR = 3.629), and the use of corticosteroid (AOR = 0.470) were also significantly associated with CTS. CONCLUSION: Similar to the findings of other studies, this study identified several potential risk factors for CTS. More large-scale longitudinal studies are required to establish a precise causal association.

Assessment of the Effective Management of Patients With Severe Primary Hypercholesterolemia Under Care in Family Medicine Clinics at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia.

Background Atherosclerotic cardiovascular disease (ASCVD) is the primary cause of death in Saudi Arabia. Hypercholesterolemia is a prevalent risk factor that can lead to ASCVD. The American College of Cardiology/American Heart Association (ACC/AHA) guidelines have provided recommendations for managing severe primary hypercholesterolemia, defined as medically well adults 21-75 years of age with low-density lipoprotein cholesterol (LDL-C) ≥190 mg/dL (≥4.9 mmol/L). Underutilization of the guideline recommendations has led to concern and the need for further review. This study aims to review the management of severe primary hypercholesterolemia in the Family Medicine and Polyclinics at King Faisal Specialist Hospital and Research Centre (KFSH&RC) in Riyadh, Saudi Arabia. Methodology In this retrospective cohort study, data were obtained from electronic medical records of patients aged 21-75 years who received care in the Family Medicine and Polyclinics at KFSH&RC in Riyadh with LDL-C ≥190 (≥4.9 mmol/L). The data collected included demographics, body mass index (BMI), LDL-C blood level, and lipid-lowering medications prescribed. We measured the prevalence of hypercholesterolemia, reviewed if appropriate statin therapy was prescribed as per the ACC/AHA guidelines, and determined if treated patients with severe primary hypercholesterolemia achieved LDL-C ≤100 mg/dL (≤2.6 mmol/L) from January 1, 2015, until June 30, 2020. Results The prevalence of hypercholesterolemia was 7.4%. The sample size studied included 195 patients. The majority of patients were aged 40-59 years and were either overweight or obese. Treatment with a moderate-intensity statin was observed in 46.4% of patients, and 45.4% of patients were not prescribed a statin. The LDL-C ≤100 mg/dL (≤2.6 mmol/L) was not achieved in 88.3% of patients. Conclusions Despite guidelines, the majority of patients with severe primary hypercholesterolemia are inadequately managed. High-risk patients need to be diagnosed appropriately so that they receive proper treatment to prevent ASCVD. We encourage adherence to established guidelines in the management of severe primary hypercholesterolemia to prevent premature ASCVD.

Association Between Vitamin D Levels and Glycemic Control Among Adult Diabetic Patients in Riyadh, Saudi Arabia.

Background: Diabetes is one of the most common diseases worldwide. It can cause serious complications, such as cardiovascular events, end-stage renal disease, and blindness if not controlled. Vitamin D is believed to play an essential role in glucose metabolism and insulin resistance. However, few studies have been conducted in Saudi Arabia to confirm or reject this hypothesis. Thus, this study explored the relationship between vitamin D levels and glycemic control in a Saudi diabetic population. MATERIALS AND METHODS: This is a retrospective cohort study including all adults 18 years of age or older diagnosed with diabetes who underwent at least five years of regular follow-up at the family medicine clinic at the King Faisal Specialist Hospital (KFSH) from January 2015 to January 2021. Data were obtained from the patients' medical records and included detailed histories, physical examination records, and laboratory findings. Participants were divided into vitamin D deficiency and vitamin D sufficiency groups based on vitamin D levels. RESULTS: A total of 370 patients with type 2 diabetes mellitus were enrolled in the study. The majority of the patients (60%) were over 65 years of age. The mean serum 25(OH) vitamin D level of the participants was 62.75 ± 22.79 nmol/L. There was a significant association between glycemic control and vitamin D levels (p < 0.001). The mean level of vitamin D was higher in the good glycemic control group (70.96 ±22.66) than in the poor glycemic control group (54.81 ±19.98). A total of 13.74% (25) of the good glycemic control group had vitamin D levels < 50 nmol/L, while 52.13% (98) of the poor glycemic control had vitamin D levels < 50 nmol/L. Patients with poor glycemic control were 2.4 times more likely to have low vitamin D levels than patients in the well-controlled glycemic group. CONCLUSION: Based on the study results, serum vitamin D has a significant inverse relationship with HbA1c levels among diabetics. This finding highlights the need for routine screening of vitamin D status in all patients with diabetes and early treatment for those found to be deficient.

Clinical and epidemiological aspects of herpes zoster disease in a primary care setting in Riyadh, Saudi Arabia: A retrospective cohort study.

Context: Herpes zoster (HZ), or shingles, is one of the most common infectious diseases. HZ can be associated with other diseases, such as cancer and immunocompromised conditions. Thus, early recognition of the disease characteristics and clinical manifestations is critical to decrease the disease burden and to avoid further complications. Aim: To assess the epidemiology of HZ disease, its clinical manifestations, coexisting and post-existing conditions, complications, and management among patients in a primary care setting. Subjects and Methods: This was a retrospective, single-armed, cohort study. Data of all patients diagnosed with HZ, aged 18 years and older, who visited the Family Medicine Department at King Faisal Specialist Hospital and Research Center from January 2014 to August 2021 were reviewed from their medical records. All data analyses were performed using IBM Statistical Package for the Social Sciences (SPSS) statistical software, version 20.0. Results: A total of 330 cases were included over the study period. The male-to-female ratio was 1:2, with a higher occurrence of HZ (44.5%) in those aged ≥ 50 years. Only 4.5% of the patients were recipients of zoster vaccines. Thoracic dermatome was the most affected dermatome (38%). The most common coexisting disease was diabetes (21.5%). The most common post-existing disease was cardiovascular disease (3%), and the most common complication was postherpetic neuralgia (15.2%). Suboptimal dosage of acyclovir was the most commonly used treatment for HZ infections (69.7%). Conclusions: Zoster vaccination uptake was low. A national program for adult vaccination, including zoster vaccination, should be developed, and a guideline to direct primary health-care professionals in the management of HZ infections should be implemented.
