Gürbüz M, Gencer G. Retrospective analysis of serologic test requests in the diagnosis of viral hepatitis: Inappropriate test requests and cost. Medicine (Baltimore) 2024; 103:e39332. [PMID: 39121251 PMCID: PMC11315476 DOI: 10.1097/md.0000000000039332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Accepted: 07/26/2024] [Indexed: 08/11/2024] Open
Abstract
The rational laboratory use and implementation of test ordering procedures aim to reduce unnecessary test requests. This study aimed to determine the financial burden caused by inappropriate serological test requests for viral hepatitis and to investigate physicians' reasons for making unnecessary test requests. We performed a retrospective evaluation of inappropriate requests for hepatitis serology testing and the financial burden they caused at a tertiary care hospital over a 1-year period. The study found 2183 (3.84%) inappropriate test requests, costing $3309.00. Of these, 357 were same-day repeat requests and 1826 were requests not following diagnostic algorithms. In the logistic regression analysis of the factors affecting unnecessary test requests, a statistically significant difference was found between whether the unit was internal or surgical, whether the request came from inpatient services or outpatient clinics, and the professional titles (P < .05). Both types of inappropriate requests were more common among male physicians (P < .05). The highest rates of inappropriate test requesting were in physical therapy and rehabilitation, pediatrics, and adult emergency units. To identify the reasons behind unnecessary test requests, 135 physicians from 23 different departments participated in the survey. The main reasons for requesting tests were identified as protecting against malpractice and fears of misdiagnosis or overlooking a diagnosis. It has been observed that physicians often order tests routinely, without being fully familiar with standard test ordering procedures based on diagnostic algorithms, and lacking knowledge about rational laboratory use. The cost of tests is mostly unknown to clinicians. The study concludes that there are laboratory tests that incur much higher costs. When this assessment is applied to the entire laboratory, it becomes clear how significant a financial burden, unnecessary workload, and loss of time this situation can cause. Identifying the presence of unnecessary test requests is the first step in preventing them. Appropriate measures include highlighting these issues, providing necessary information, and offering in-service training.

Overdiagnosis and overuse of diagnostic and screening tests in low-income and middle-income countries: a scoping review. BMJ Glob Health 2022; 7:bmjgh-2022-008696. [PMID: 36316027 PMCID: PMC9442491 DOI: 10.1136/bmjgh-2022-008696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 07/12/2022] [Indexed: 11/29/2022] Open
Abstract
Objective Overdiagnosis and overuse of healthcare services harm individuals, take resources that could be used to address underuse, and threaten the sustainability of health systems. These problems are attracting increasing attention in low-income and middle-income countries (LMICs). Unaware of any review of relevant evidence, we conducted a scoping review of the evidence around overdiagnosis and overuse of diagnostic and screening tests in LMICs. Design Scoping review. Methods We searched PubMed, Embase, PsycINFO, Global Index Medicus for relevant studies published until 24 May 2021, with no restrictions on date or language. We categorised included studies by major focus (overdiagnosis, overuse of tests, or both) and main themes (presence or estimates of extent; drivers; consequences and solutions). Results We identified 2763 unique records and included 162 articles reporting on 154 studies across 55 countries, involving over 2.8 million participants and/or requests for tests. Almost half the studies focused on overdiagnosis (70; 45.5%), one-third on overuse of tests (61; 39.6%) and one-fifth on both (23; 14.9%). Common overdiagnosed conditions included malaria (61; 39.6%) and thyroid cancer (25; 16.2%), estimated to be >70% in China. Overused tests included imaging (n=25 studies) such as CT and MRI; laboratory investigations (n=18) such as serological tests and tumour markers; and procedures (n=14) such as colonoscopy. Drivers included fear of conflict with patients and expanding disease definitions. Common consequences included unnecessary treatments such as antimalarials, and wasted resources, with costs of malaria overdiagnosis estimated at US$86 million in Sudan in 1 year alone. Only 9% of studies discussed solutions, which included addressing inappropriately lowered diagnostic thresholds and reforming test-ordering processes. Conclusions Overdiagnosis and overuse of tests are widespread in LMICs and generate significant harm and waste. Better understanding of the problems and robust evaluation of solutions is needed, informed by a new global alliance of researchers and policy-makers.

Abstract
BACKGROUND The negative impact of unnecessary diagnostic tests on healthcare systems and patients has been widely recognized. Medical researchers in various countries have been devoting effort to reduce unnecessary diagnostic tests by using different types of interventions, including information and communications technology-based (ICT-based) intervention, educational intervention, audit and feedback, the introduction of guidelines or protocols, and the reward and punishment of staff. We conducted a review of ICT based interventions and a comparative analysis of their relative effectiveness in reducing unnecessary tests. METHOD A systematic Boolean search in PubMed, EMBase and EBSCOhost research databases was performed. Keyword search and citation analysis were also conducted. Empirical studies reporting ICT based interventions, and their implications on relative effectiveness in reducing unnecessary diagnostic tests (pathology tests or medical imaging) were evaluated independently by two reviewers based on a rigorously developed coding protocol. RESULTS 92 research articles from peer-reviewed journals were identified as eligible. 47 studies involved a single-method intervention and 45 involved multi-method interventions. Regardless of the number of interventions involved in the studies, ICT-based interventions were utilized by 71 studies and 59 of them were shown to be effective in reducing unnecessary testing. A clinical decision support (CDS) tool appeared to be the most adopted ICT approach, with 46 out of 71 studies using CDS tools. The CDS tool showed effectiveness in reducing test volume in 38 studies and reducing cost in 24 studies. CONCLUSIONS This review investigated five frequently utilized intervention methods, ICT-based, education, introduction of guidelines or protocols, audit and feedback, and reward and punishment. It provides in-depth analysis of the efficacy of different types of interventions and sheds insights about the benefits of ICT based interventions, especially those utilising CDS tools, to reduce unnecessary diagnostic testing. The replicability of the studies is limited due to the heterogeneity of the studies in terms of context, study design, and targeted types of tests.

Abstract
To reduce unnecessary laboratory testing, a three-phase intervention was designed by students to decrease serum folate laboratory testing in the inpatient setting. These included an educational phase, a personalized feedback phase, and the uncoupling of orders in the electronic medical record. Average monthly serum folate ordering decreased by 87% over the course of the intervention, from 98.4 orders per month at baseline to 12.7 per month in the last phase of the intervention. In the segmented regression analysis, joint ordering of folate and vitamin B12 significantly decreased during the intervention ([INCREMENT]slope = -4.22 tests/month, p = .0089), whereas single ordering of vitamin B12 significantly increased ([INCREMENT]slope = +5.6 tests/month; p < .001). Our intervention was successful in modifying ordering patterns to decrease testing for a deficiency that is rare in the U.S. population.

Abstract
Scientific evidence showing the benefits of early initiation of antiretroviral therapy (ART) prompted World Health organization (WHO) to recommend that all persons diagnosed as HIV positive should commence ART irrespective of CD4 count and disease progression. Based on this recommendation, countries should adopt and implement the HIV "Treat All" policy to achieve the UNAIDS 90-90-90 targets and ultimately reach epidemic control. Attaining this goal along the HIV treatment cascade depends on the laboratory to monitor progress and measure impact. The laboratory plays an important role in HIV diagnosis to attain the first 90 and in viral load (VL) and HIV drug resistance testing to reinforce adherence, improve viral suppression, and measure the third 90. Countries in the Caribbean region have endorsed the WHO HIV "Treat all" recommendation; however, they are faced with diminishing financial resources to support laboratory testing, seen as a rate-limiting factor to achieving this goal. To improve laboratory coverage with fewer resources in the Caribbean there is the need to optimize laboratory operations to ensure the implementation of high quality, less expensive evidence-based approaches that will result in more efficient and effective service delivery. Suggested practical and innovative approaches to achieve this include: (1) targeted testing within HIV hotspots; (2) strengthening sample referral systems for VL; (3) better laboratory data collection systems; and (4) use of treatment cascade data for programmatic decision-making. Furthermore, strengthening quality improvement and procurement systems will minimize diagnostic errors and guarantee a continuum of uninterrupted testing which is critical for routine monitoring of patients to meet the stated goal.
