Abstract
Pre-analytical deficiencies (PADs) are a major source of errors in anatomical pathology, accounting for about 70% of laboratory deficiencies. These can lead to incorrect diagnoses, delayed treatments, and increased healthcare costs. As part of a quality improvement initiative, we retrospectively identified and characterized 237 PADs documented over a 1-year period in a tertiary care academic center. The most common PADs were errors in specimen procurement (56%), handling of samples within the lab (16%), accessioning (10%), incomplete requisitions (9%), and transportation-related issues (7%). Strategies were then devised to mitigate these errors. Categorization of pre- and intra-laboratory PADs was refined into eight categories (collection, requisition, specimen container, transportation, receiving, accessioning, preparation, and communications) in the laboratory information system. Mandatory PAD documentation was implemented for accessioning staff. Post-implementation, prospective analysis identified that the most common PADs were related to surgical requisitions (75%). Among these, missing ordering physician's signature was the most common, accounting for 67.7% of requisition-related PADs and 50.8% of all PADs. Other common PADs included incomplete information of specimens, clinical information, patient information, physician information, source location, collection time, incorrect requisition forms, and illegible handwritten information. This study highlights the importance of identifying and addressing PADs in the anatomical pathology laboratory setting as well as the potential benefits of implementing standardized documentation and quality improvement processes to address these deficiencies.

J Cytol 2022; 39:116-120. [PMID: 36277805 PMCID: PMC9585814 DOI: 10.4103/joc.joc_160_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 06/01/2022] [Accepted: 08/01/2022] [Indexed: 11/20/2022] Open
Abstract
Background: A laboratory requisition form (LRF) is the main communication link between the laboratories and the clinicians. In a cytopathology laboratory, incomplete forms with inadequate information significantly impact the quality of the results and waste precious time of the lab. Aims: The aim of this study was to audit the LRFs for adequacy of demographic and clinical data and to analyze the reasons for the same. Settings and Design: A retrospective study was conducted in the cytopathology laboratory of a tertiary care center. Materials and Methods: All the original LRFs received for Pap smears and FNACs of 1-month duration were retrieved. The forms were scrutinized for the presence of specific parameters which were classified as patient information, clinician information and clinical information. In addition to the completeness of the form, clarity of the data was also noted. Statistical Analysis: The data were entered on excel worksheets and percentage of Pap smear and FNAC forms lacking information of various parameters was calculated. Results: A total of 431 LRFs were received in the month of January 2020. These included 274 Pap smear LRFs and 157 FNAC LRFs. Patient information was mentioned in predominantly all the forms, however, clinician and clinical information, which is indispensible for reporting, was missing in a significant proportion of the Pap smear and fine needle aspiration cytology (FNAC) forms. Conclusions: Receiving inadequately filled LRFs has been an age-old problem in all medical laboratories. Audit of inadequacy of LRFs helped in assessing the prevailing practices in the hospital and gave an insight into the quality of information available to the cytologists for reporting. Many clinicians withhold information out of ignorance about its importance or due to lack of time to fill up the details on the LRF. Also, filling out a LRF is a task usually delegated to the junior doctor in the OPD and the significance of filling the LRF correctly and comprehensively is often not emphasized upon adequately by the senior clinicians. This audit helped us taking preventive action by giving feedback to the clinicians and emphasizing to them the importance of clinical data on the LRF and in improvising the LRF using a more objective and user-friendly format.

Abstract
BACKGROUND Surveillance of antimicrobial resistance (AMR) in horses is important to aid empirical treatment decisions and highlight emerging AMR threats. OBJECTIVE To describe the AMR patterns of common groups of bacteria from clinical submissions from horses in the UK during 2018, and to determine how this varies by sample site and type of submitting veterinary practice. STUDY DESIGN Prospective observational study. METHODS All data on bacterial culture and subsequent antimicrobial susceptibility testing (AST) collected in 2018 from six large equine diagnostic laboratories were included. Resistance patterns were analysed including resistance to 1 or 2 antimicrobial classes, multidrug resistance (MDR), extensively drug resistant (XDR), resistance to highest priority critically important antimicrobials and isolates where there was no readily available treatment for adult horses in the UK. Submitting practices were classified according to whether they treated referral cases or not (first opinion). Comparisons between proportions and resistance for each bacterial group and sample site was performed using Chi-squared (or Fisher's exact test). RESULTS A total of 6,018 bacterial isolates from 4,038 diagnostic submissions were included from respiratory (n = 1555), urogenital (n = 1,010), skin/hair/wound/abscess (n = 753), surgical site infection (SSI) /catheter-related-infection (CRI) /orthopaedic infections (n = 347) and unknown/'other' submissions (n = 373). There were 2,711 Gram-negative isolates and 3,307 Gram-positive isolates. Prevalence of MDR for E. coli was 31.7%, Staphylococcus spp. 25.3% and > 25% for the majority of bacterial isolates from SSI/CRI/orthopaedic submissions. For Enterococcus spp. there was no readily available treatment for adult horses in the UK in 30.2% of positive submissions. MDR was significantly higher from referral hospital than first opinion submissions for the majority of pathogens (except Actinobacillus spp. and Pasteurella spp. and β-haemolytic Streptococcus spp.). MAIN LIMITATIONS Since culture and susceptibility results are not systematic analyses based on harmonised methods, selection bias could impact the findings. CONCLUSIONS Ongoing surveillance is essential to understand emerging patterns of resistance. MDR is high in SSI/CRI/orthopaedic infections, which is important for hospital biosecurity and guiding treatment decisions. Harmonisation of diagnostic procedures and interpretation of results amongst veterinary laboratories will improve AMR surveillance and data comparison among laboratories.

Abstract
OBJECTIVES The aim of this study was to analyse blood requisition forms sent by clinicians in a tertiary care hospital to the transfusion service to ascertain their completeness and correctness. A secondary objective was to study the effect of continuing medical education (CME) in a hospital setting on clinician's behaviour regarding the importance of details that ought to be mentioned on blood requisition forms. BACKGROUND Transfusion audits are useful tools in the evaluation and education of those requesting blood components. METHODS/MATERIALS This was a prospective, observational study conducted in the department of Transfusion Medicine at a tertiary-level healthcare centre from June 2019 to December 2019. The study was divided into two phases: pre-CME (P1) and post-CME (P2). In both phases, an audit for assessing completeness and correctness of blood requisition forms, which were divided into four sections, was performed. A scoring system was devised to compare both phases. RESULTS In the P1 phase, 45.77% of the blood requisition form entries were complete and correct; 23.45% of incomplete entries were generated by emergency and trauma. In the P2 phase, 76.75% of the blood requisition form entries were complete and correct; 35.09% of the incomplete entries were generated by obstetrics and gynaecology. Complete and correct entries increased from 45.7% (P1) to 76.75% (P2). Scores of P1 were found to be lower than scores of P2 for all four sections. Cumulative mean score for P1 (20687) was found to be significantly lower than the mean score for P2 (30870). CONCLUSION Audit and CME regarding different aspects of transfusion medicine practices play a major role in the improvement of transfusion practices in hospitals.

Abstract
BACKGROUND Thrombophilia-screen tests are specialised haemostasis tests that are affected by numerous unique patient variables including the presence of acute thrombosis, the concomitant use of medication and patient demographics. Complete information on the request form is therefore crucial for the haematological pathologist to make patient-specific interpretation of patients' results. OBJECTIVES To assess the completeness of thrombophilia-screen test request forms and determine the impact of provision of incomplete information, on the interpretive comments generated by reporting haematological pathologists. To assess the impact of an educational session given to clinicians on the importance of providing all the relevant information on the request forms. METHOD Two retrospective audits, each covering 3 months, were performed to evaluate the completeness of demographic and clinical information on thrombophilia-screen request forms and its impact on the quality of the interpretive comments before and after an educational intervention. RESULTS One hundred and seventy-one request forms were included in the first audit and 146 in the second audit. The first audit revealed that all 171 thrombophilia-screen request forms had complete patient demographic information but none had clinical information. Haematological pathologists only made generic comments which could not be applied to a specific patient. The second audit, conducted after a physician educational session, did not reveal any improvement in the clinical information provision by the test-ordering physicians. This was reportedly due to the lack of space on the request form. The interpretive comments therefore remained generic and not patient-specific. CONCLUSION Physicians' failure to provide relevant clinical information made it impossible for pathologists to make patient-specific interpretation of the results. A single physician education session did not change the practice, reportedly due to the inappropriate design of the test request form. Further studies are required to investigate the impact of an improved request form and the planned electronic test requesting.

Abstract
BACKGROUND Auditing and education are the tools for improvement in the transfusion practices. Clinicians are not providing patient's demographic data and medical history to the blood bank that required transfusion. This missing information in blood request forms can lead to transfusion reactions to the patient. So we planned to analyse the blood request forms received at our blood bank and the impact of educational program for the clinicians. METHODS A total of 6894 blood request forms were received from the month of July 2014 to December 2014 at a blood bank in Amritsar, India. We evaluated for completeness of the blood request form in parameter columns like second identification (CR No. or Father/Husband Name), diagnosis, pre transfusion hematological parameters, quality and quantity of blood component required, history of previous transfusion and adverse transfusion reaction, urgency of transfusion, medical officer name and signature, phlebotomist name and signature etc. A series of CMEs on "Safe Transfusion Practices" were organized for clinicians and hospital staff from 1st August 2014 and improvement in clinicians' behavior was analysed. RESULTS A total of 60.83% requests were not filled completely during the study period. Of these 91.42% were in the month of July, which decreased to 48.76% in the month of December 2014 with a total improvement of 42.66%. Incomplete second identification (91.03%) and history of previous transfusion and adverse transfusion reactions (80.21%) were the commonest incomplete fields in the month of July 2014. In the month of December 2014, an improvement in incomplete second identification was observed (12.8%) however phlebotomist signature was still a major incomplete field (45.19%). A statistically significant (p value = 0.004, paired 't' test) improvement in completeness of forms was observed. SUMMARY Results of medical audit and using those as a basis for developing a highly targeted educational program, can improve the clinicians' approch towards transfusion practices.

Abstract
The total testing process consists of various phases from the pre-preanalytical to the post-postanalytical phase, the so-called brain-to-brain loop. With improvements in analytical techniques and efficient quality control programmes, most laboratory errors now occur in the extra-analytical phases. There has been recent interest in these errors with numerous publications highlighting their effect on service delivery, patient care and cost. This interest has led to the formation of various working groups whose mission is to develop standardized quality indicators which can be used to measure the performance of service of these phases. This will eventually lead to the development of external quality assessment schemes to monitor these phases in agreement with ISO15189:2012 recommendations. This review focuses on potential errors in the extra-analytical phases of clinical chemistry laboratory testing, some of the studies performed to assess the severity and impact of these errors and processes that are in place to address these errors. The aim of this review is to highlight the importance of these errors for the requesting clinician.

Abstract
Preanalytical steps are the major sources of error in clinical laboratory. The analytical errors can be corrected by quality control procedures but there is a need for stringent quality checks in preanalytical area as these processes are done outside the laboratory. Sigma value depicts the performance of laboratory and its quality measures. Hence in the present study six sigma and Pareto principle was applied to preanalytical quality indicators to evaluate the clinical biochemistry laboratory performance. This observational study was carried out for a period of 1 year from November 2015-2016. A total of 1,44,208 samples and 54,265 test requisition forms were screened for preanalytical errors like missing patient information, sample collection details in forms and hemolysed, lipemic, inappropriate, insufficient samples and total number of errors were calculated and converted into defects per million and sigma scale. Pareto`s chart was drawn using total number of errors and cumulative percentage. In 75% test requisition forms diagnosis was not mentioned and sigma value of 0.9 was obtained and for other errors like sample receiving time, stat and type of sample sigma values were 2.9, 2.6, and 2.8 respectively. For insufficient sample and improper ratio of blood to anticoagulant sigma value was 4.3. Pareto`s chart depicts out of 80% of errors in requisition forms, 20% is contributed by missing information like diagnosis. The development of quality indicators, application of six sigma and Pareto`s principle are quality measures by which not only preanalytical, the total testing process can be improved.

Abstract
In recent decades, healthcare organizations have undergone a significant transformation with the integration of Information and Communication Technologies within healthcare operations to improve healthcare services. Various technologies such as Hospital Information Systems (HIS), Electronic Health Records (EHR) and Laboratory Information Systems (LIS) have been incorporated into healthcare services. The aim of this study is to evaluate the completeness of outpatients' laboratory paper based request forms in comparison with a electronic laboratory request system. This study was carried out in the laboratory department at King Abdulaziz Medical City (KAMC), National Guard Health Affairs, Riyadh, Saudi Arabia. We used a sample size calculator for comparing two proportions. We estimated the sample size to be 228 for each group. Any laboratory requests including paper and electronic forms were included. We categorized the clarity of the forms into understandable, readable, and unclear. A total of 57 incomplete paper forms or 25% were identified as being incomplete. For electronic forms, there were no incomplete fields, as all fields were mandatory, therefore, rendering them complete. The total of understandable paper-based laboratory forms was 11.4%. Additionally, it was found that the total of readable was 33.8% and the total for unclear was 54.8%, while for electronic-based forms, there were no unclear forms. Electronic based laboratory forms provide a more complete, accurate, clear, and understandable format than paper-based laboratory records. Based on these findings, KAMC should move toward the implementation of electronic-based laboratory request forms for the outpatient laboratory department.

Abstract
Background: Inadequately completed laboratory test request forms contribute to preanalytical errors and limit the advice of pathologists when interpreting laboratory test results. Educating clinicians about this has been proposed by several studies as a strategy to reduce the occurrence. Aim: We aimed to determine the effectiveness of such education on the prevalence of adequately completed laboratory test request forms. Subjects and Methods: This was a quasi-experimental study conducted at the chemical pathology laboratory of the Lagos University Teaching Hospital, Nigeria. Incoming laboratory request forms were audited for a period of 1 month looking out for eight data variables. Subsequently, intensive clinician education was undertaken via seminars, publications, and orientation programs on 670 clinicians for 6 weeks duration. After that, a repeat audit for the same data variables was conducted for another period of 1 month. A Z-test of significance for the comparison of independent proportions was conducted for form errors pre- and post-intervention. Results: Error rates for missing variables pre- and post-clinician education were: Name pre = 0 (0%), post = 0 (0%); age pre = 330 (21.6%), post = 28 (1.9%), P < 0.001; gender pre = 64 (4.2%), post = 53 (3.6%), P = 0.37; hospital number pre = 848 (55.6%), post = 524 (35.3%), P < 0.001; clinician name pre = 165 (10.8%), post = 64 (4.3%), P < 0.001; ward/clinic pre = 311 (20.4%), post = 235 (15.8%), P < 0.01; clinical diagnosis pre = 220 (14.4%), post = 33 (2.2%), P < 0.001; specimen type pre = 169 (11.1%), post = 116 (7.8%), P < 0.01, respectively. Conclusion: There was an improvement in the inadequate completion of laboratory request forms after clinicians were educated on proper completion using various interactive media, showing that it is an effective strategy. However, further studies are required to identify which educational strategy is most effective in reducing error rates in laboratory test request forms.

Abstract
Background The laboratory request form (LRF) is a communication link between laboratories, requesting physicians and users of laboratory services. Inadequate information or errors arising from the process of filling out LRFs can significantly impact the quality of laboratory results and, ultimately, patient outcomes. Objective We assessed routinely-submitted LRFs to determine the degree of correctness, completeness and consistency. Methods LRFs submitted to the Department of Haematology (DH) and Blood Transfusion Services (BTS) of Aminu Kano Teaching Hospital in Kano, Nigeria, between October 2014 and December 2014, were evaluated for completion of all items on the forms. Performance in four quality indicator domains, including patient identifiers, test request details, laboratory details and physician details, was derived as a composite percentage. Results Of the 2084 LRFs evaluated, 999 were from DH and 1085 from BTS. Overall, LRF completeness was 89.5% for DH and 81.2% for BTS. Information on patient name, patient location and laboratory number were 100% complete for DH, whereas only patient name was 100% complete for BTS. Incomplete information was mostly encountered on BTS forms for physician’s signature (60.8%) and signature of laboratory receiver (63.5%). None of the DH and only 9.4% of BTS LRFs met all quality indicator indices. Conclusion The level of completion of LRFs from these two departments was suboptimal. This underscores the need to review and redesign the LRF, improve on training and communication between laboratory and clinical staff and review specimen rejection practices.

Abstract
Communication is an essential element of good medical practice also in pathology. In contrast to technical or diagnostic skills, communication skills are not easy to define, teach, or assess. Rules almost do not exist. In this paper, which has a rather personal character and cannot be taken as a set of guidelines, important aspects of communication in pathology are explored. This includes what should be communicated to the pathologist on the pathology request form, communication between pathologists during internal (interpathologist) consultation, communication around frozen section diagnoses, modalities of communication of a final diagnosis, with whom and how critical and unexpected findings should be communicated, (in-)adequate routes of communication for pathology diagnoses, who will (or might) receive pathology reports, and what should be communicated and how in case of an error or a technical problem. An earlier more formal description of what the responsibilities are of a pathologist as communicator and as collaborator in a medical team is added in separate tables. The intention of the paper is to stimulate reflection and discussion rather than to formulate strict rules.

Abstract
Objective: Manual data-entry of handwritten laboratory test requests into electronic information systems has implications for data accuracy. This study sought to identify the types and number of errors occurring for handwritten serology test requests received from outpatient clinics. Methods: A 15-day audit at a serology laboratory in Sydney, Australia, compared the content of all transcribed serology outpatient test requests in the laboratory information system with the handwritten request form. Results: One or more errors were detected in 67/627 (10.7%) audited requests ( N=68 errors). Fifty-one of the errors (75.0%) were transcription errors: the wrong test was transcribed in 40/68 cases (58.8%) – ten of these occurred when the abbreviations ‘HBsAb’ and ‘HBsAg’ were confounded for one another – and transcribed requests were missing a test in 11/68 cases (16.2%). The remaining 17 non-transcription errors (25.0%) described request forms not signed by the ordering clinician, mislabelled specimens, and wrong tests due to computer algorithm errors. Conclusions: Manual data-entry of handwritten serology requests is an error-prone process. Electronic ordering has the potential to eliminate illegible handwriting and transcription errors, thus improving data accuracy in hospital information systems.

Abstract
OBJECTIVE The objective was to study radiologists' experiences of written and oral communication with referring clinicians, and its potential implications for decision making and patient care. METHODS Focus group discussions with 12 radiologists were carried out. Content analysis was used for interpretation of the data. RESULTS Radiologists reported many problems with the request forms: improper choice of imaging examinations and procedures, insufficient patient history/information, unclear clinical questions, lack of specific terms and unclear abbreviations on the request form. Radiologists also mentioned other difficulties: insufficient attention among participating clinicians during conferences, difficulties in reaching the referring clinicians by telephone, and communication difficulties in making priorities between patients. To overcome these problems, radiologists suggested increased contacts between radiologists and clinicians, and educational activities. CONCLUSION A number of difficulties in oral and written communication were highlighted. The use of medical imaging may be optimized by joint discussions on indications and methodology and educational activities, such as lectures, seminars and conferences, directed to the medical community at large. PRACTICE IMPLICATIONS Improved communication between radiologists and referring clinicians should be encouraged to ensure diagnostic quality, correct patient prioritization and patient safety, and to avoid unnecessary delays and costs.

Abstract
Introduction Request forms are important means of communication between physicians and diagnostic service providers. Pre-analytical errors account for over two thirds of errors encountered in diagnostic service provision. The importance of adequate completion of request forms is usually underestimated by physicians which may result in medical errors or delay in instituting appropriate treatment. The aim of this study was to audit the level of completion of request forms presented at a multidisciplinary diagnostic center. Methods A review of all requests forms for investigations which included radiologic, laboratory and cardiac investigations received between July and December 2011 was performed to assess their level of completeness. The data was entered into a spreadsheet and analyzed. Results Only 1.3% of the 7,841 request forms reviewed were fully completed. Patient's names, the referring physician's name and gender were the most completed information on the forms evaluated with 99.0%, 99.0% and 90.3% completion respectively. Patient's age was provided in 68.0%, request date in 88.2%, and clinical notes/ diagnosis in 65.9% of the requests. Patient's full address was provided in only 5.6% of requests evaluated. Conclusion This study shows that investigation request forms are inadequately filled by physicians in our environment. Continuous medical education of physicians on the need for adequate completion of request forms is needed.

Blood component use in a sub-Saharan African country: results of a 4-year evaluation of diagnoses associated with transfusion orders in Namibia. Transfus Med Rev 2014; 29:45-51. [PMID: 25573416 DOI: 10.1016/j.tmrv.2014.11.003] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2014] [Revised: 11/17/2014] [Accepted: 11/20/2014] [Indexed: 11/24/2022]
Abstract
National blood use patterns in sub-Saharan Africa are poorly described. Although malaria and maternal hemorrhage remain important drivers of blood demand across Africa, economic growth and changes in malaria, HIV/AIDS, and noncommunicable disease epidemiology may contribute to changes in blood demand. We evaluated indications for blood use in Namibia, a country in southern Africa, using a nationally representative sample and discuss implications for the region. Clinical and demographic data related to the issuance of blood component units in Namibia were reviewed for a 4-year period (August 1, 2007-July 31, 2011). Variables included blood component type, recipient age and sex, and diagnosis. Diagnoses reported by clinicians were reclassified into International Statistical Classification of Diseases, 10th Revision categories. Multiple imputation methods were used to complete a data set missing age, sex or diagnosis data. Descriptive analyses were conducted to describe indications for transfusions and use of red blood cells (RBCs), platelets, and plasma. A total of 39,313 records accounting for 91,207 blood component units were analyzed. The median age of Namibian transfusion recipients was 45 years (SD, ±19). A total of 78,660 RBC units were issued in Namibia during the study period. Red blood cells transfused for "unspecified anemia" accounted for the single largest category of blood issued (24,798 units). Of the overall total, 38.9% were for diseases of the blood and blood-forming organs (D50-D89). Infectious disease (A00-B99), pregnancy (O00-O99), and gastrointestinal (K20-K93) accounted for 14.8%, 11.1%, and 6.1% of RBC units issued, respectively. Although a specific diagnosis of malaria accounted for only 2.7% of pediatric transfusions, an unknown number of additional transfusions for malaria may have been categorized by requesting physicians as unspecified anemia and counted under diseases of blood forming organs. During the study period, 9751 units of fresh-frozen plasma were issued. Nearly one-quarter of these units (23.1%) were issued for gastrointestinal (K20-K93) diagnoses. Malignant neoplasms (C00-C97) accounted for 38.1% of 2978 platelet units issued. Blood use in Namibia reflects changes in the health care system due to economic development, improvement in HIV/AIDS and malaria epidemiology, high rates of health care facility-based childbirth, and access to noncommunicable disease treatment. However, better documentation of the indications for transfusion is needed to confirm these observations. Changing patterns of health care will result in changing demands for blood components. Improved methods to evaluate blood use patterns in sub-Saharan Africa may help set realistic national blood collection goals.

Abstract
Background It is common practice in most chemical pathology laboratories for reflective immunofixation electrophoresis (IFE) to occur following the detection or suspicion of a paraprotein on serum protein electrophoresis (SPEP). The chemical pathology laboratory at Inkosi Albert Luthuli Central Hospital (IALCH) in Durban, South Africa, is currently the only non-private laboratory in the KwaZulu Natal province that performs SPEP analysis, with current practice requiring that the clinician request IFE following suggestion by the laboratory after a suspicious SPEP result. Objectives To review the current process for IFE at IALCH in the context of reflective testing and to examine the use of the alpha-2-globulin/alpha-1-globulin ratio as a predictor of a positive IFE result. Methods Data for 1260 consecutive SPEP tests performed at the IALCH National Health Laboratory Service were collected between February and July 2011. SPEP and IFE were performed with a Sebia Hydrasys automated electrophoresis system. The alpha-2-globulin/alpha-1-globulin ratio was calculated using density of corresponding fractions on SPEP. Results Analysis revealed that of the 1260 SPEPs performed during the analysis period, 304 IFEs were suggested by the reviewing pathologist. A total of 45 (15%) of the suggested IFEs were subsequently requested by the attending clinicians. Almost half (46.5%) (n = 20) of the suggested IFEs that were performed revealed the presence of a paraprotein. There was no statistically-significant difference between the alpha-2-globulin/alpha-1-globulin ratio for patients with positive or negative IFEs (p-value = 0.2). Conclusions This study reveals the need for reflective addition of IFE testing by the laboratory following suspicious findings on SPEP.

Abstract
Background In recent years inappropriate and excessive use of clinical laboratory facilities has become a cause of concern and has led to concurrent rise in the laboratory errors and the health care costs. The aim of the study was to find out the frequency of incomplete laboratory request forms, inappropriate test requests at various professional levels and the financial impact of uncollected reports at Armed Forces Institute of Pathology (AFIP) and Combined Military Hospital (CMH) Laboratory Rawalpindi. Methods The cross-sectional descriptive study was conducted during a three month period from April to June 2012 at AFIP and CMH Laboratory Rawalpindi. A total of 1000 laboratory request forms were collected and scrutinized for completion from AFIP (n=500) and CMH Rawalpindi laboratory (n=500). 536 request forms of costly/specialized tests from different departments of AFIP were studied to find out the professional level of test request. The total number of tests performed at AFIP during the study period and number of uncollected reports were noted. The financial impact of these uncollected reports was also calculated. Collection of data and sorting were done manually. Patient confidentiality was maintained. Microsoft excel software and SPSS-17 were used for analysis. The study was approved by the Institutional Ethical Review Committee. Results Out of a total of 1000 forms studied none was completely filled with clinical notes being present in only 2.4% and 13% of forms sent to CMH and AFIP respectively. 62% of the expensive investigations were requested by specialists while 38% were ordered by residents and general practitioners but the percentage of avoidable expensive tests ordered by the general practitioners and residents was significantly higher than the specialists(p<0.001). A total of 9026 (40%) and 5046 (22%) diagnostic test reports were not collected from the Chemical pathology and Hematology departments respectively. Financial impact of uncollected reports from all the departments at AFIP collectively amounted to Pakistani Rupees (PKR) 3338201. Conclusion Processing incomplete laboratory request forms and injudicious use of laboratory facilities leads to incorrect interpretation of laboratory test results affecting outcome of the overall treatment.

Abstract
BACKGROUND Well-working health information systems are considered vital with the quality of health data ranked of highest importance for decision making at patient care and policy levels. In particular, health facilities play an important role, since they are not only the entry point for the national health information system but also use health data (and primarily) for patient care. DESIGN A multiple case study was carried out between March and August 2012 at the antenatal care (ANC) clinics of two private and one public Kenyan hospital to describe clinical information systems and assess the quality of information. The following methods were developed and employed in an iterative process: workplace walkthroughs, structured and in-depth interviews with staff members, and a quantitative assessment of data quality (completeness and accurate transmission of clinical information and reports in ANC). Views of staff and management on the quality of employed information systems, data quality, and influencing factors were captured qualitatively. RESULTS Staff rated the quality of information higher in the private hospitals employing computers than in the public hospital which relies on paper forms. Several potential threats to data quality were reported. Limitations in data quality were common at all study sites including wrong test results, missing registers, and inconsistencies in reports. Feedback was seldom on content or quality of reports and usage of data beyond individual patient care was low. CONCLUSIONS We argue that the limited data quality has to be seen in the broader perspective of the information systems in which it is produced and used. The combination of different methods has proven to be useful for this. To improve the effectiveness and capabilities of these systems, combined measures are needed which include technical and organizational aspects (e.g. regular feedback to health workers) and individual skills and motivation.

Abstract
Objective To model the financial effects of implementing a hospital-wide electronic medical record (EMR) system in a tertiary facility in Malawi. Materials and Methods We evaluated three areas of impact: length of stay, transcription time, and laboratory use. We collected data on expenditures in these categories under the paper-based (pre-EMR) system, and then estimated reductions in each category based on findings from EMR systems in the USA and backed by ambulatory data from low-income settings. We compared these potential savings accrued over a period of 5 years with the costs of implementing the touchscreen point-of-care EMR system at that site. Results Estimated cost savings in length of stay, transcription time, and laboratory use totaled US$284 395 annually. When compared with the costs of installing and sustaining the EMR system, there is a net financial gain by the third year of operation. Over 5 years the estimated net benefit was US$613 681. Discussion Despite considering only three categories of savings, this analysis demonstrates the potential financial benefits of EMR systems in low-income settings. The results are robust to higher discount rates, and a net benefit is realized even under more conservative assumptions. Conclusions This model demonstrates that financial benefits could be realized with an EMR system in a low-income setting. Further studies will examine these and other categories in greater detail, study the financial effects at different levels of organization, and benefit from post-implementation data. This model will be further improved by substituting its assumptions for evidence as we conduct more detailed studies.

Abstract
BACKGROUND Recent publications report that up to 70% of total laboratory errors occur in the pre-analytical phase. Identification of specific problems highlights pre-analytic processes susceptible to errors. The rejection of unsuitable samples can lead to delayed turnaround time and affect patient care. METHODS A retrospective audit was conducted investigating the rejection rate of routine blood specimens received at chemistry and haematology laboratories over a 2-week period. The reasons for rejection and potential clinical impact of these rejections were investigated. Thirty patient files were randomly selected and examined to assess the impact of these rejections on clinical care. RESULTS A total of 32,910 specimens were received during the study period, of which 481 were rejected, giving a rejection rate of 1.46%. The main reasons for rejection were inappropriate clotting (30%) and inadequate sample volume (22%). Only 51.7% of rejected samples were repeated and the average time for a repeat sample to reach the laboratory was about 5 days (121 h). Of the repeated samples, 5.1% had results within critical values. Examination of patient folders showed that in 40% of cases the rejection of samples had an impact on patient care. CONCLUSIONS The evaluation of pre-analytical processes in the laboratory, with regard to sample rejection, allowed one to identify problem areas where improvement is necessary. Rejected samples due to factors out of the laboratory's control had a definite impact on patient care and can thus affect customer satisfaction. Clinicians should be aware of these factors to prevent such rejections.

Abstract
PURPOSE The purpose of this study was to improve communication between the ophthalmology and histopathology departments at Royal Hallamshire Hospital, Sheffield, by effectively changing the structure and completion of the histopathology request form through the process of a successful audit. This aimed to ensure that comprehensive information was made available to the histopathologist. METHODS An audit was performed by review of 710 histopathology request forms, completed by the ophthalmology department, over a 1-year period, between July 2005 and June 2006 inclusive. Results were used to re-model the ophthalmic histopathology request form. New forms were circulated and all forms completed over a 3-month period, between January 2008 and March 2008, were reviewed, thus closing the audit loop. RESULTS On the basis of audit results of 710 histopathology request forms, a new histopathology request form was created, which was easier to complete. Review of the 224 new histopathology request forms showed improved percentages of completion of important sections of the form. CONCLUSIONS Through the audit process we have created a new ophthalmic histopathology request form that is more user-friendly for the ophthalmologist and more consistently provides the necessary information for the ophthalmic histopathologist. This has improved efficiency and effectiveness of communication between the specialities, which should contribute to minimise the chances of medical error and improved turnaround times for the planning and delivery of patient care.

Olayemi E, Asiamah-Broni R. Evaluation of request forms submitted to the haematology laboratory in a Ghanaian tertiary hospital. Pan Afr Med J 2011; 8:33. [PMID: 22121441 PMCID: PMC3201597 DOI: 10.4314/pamj.v8i1.71148] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2010] [Accepted: 03/29/2011] [Indexed: 01/12/2023] Open
Abstract
Background Laboratory request forms provide information about the laboratory test being requested for. They carry demographic data and other information such as location of patient, laboratory number, doctor’s name, signature of the doctor, telephone number of the requesting doctor. Omission of information on the forms may lead to laboratory errors. The aim of this study was to evaluate the level of completion of laboratory request forms at the haematology department of a Ghanaian tertiary hospital. Methods Three thousand request forms submitted to the haematology department between January and April 2010 were retrieved and studied. The information provided on each request form was recorded in a spread sheet and analyzed. Results The patient’s age and sex were missing in 25.6% and 32.7% of the forms respectively. About half of the request forms did not have the patient’s location. No clinical detail was provided on 22.7% of the forms. Doctors were more likely to sign their request forms and provide a name but they all failed to provide an address or a contact telephone number. Conclusion: This study demonstrates that, the standard of completion of request forms was poor. Essential information required on the forms was often missing. This can lead to limited advice given by laboratory physicians and may increase the potential for errors. Conversely, provision of all the information needed on the forms will aid laboratory diagnosis and enhance patient care and save time and resources. There should be closer interaction between clinicians and laboratory personnel to improve quality of services.

Effect of pre-analytical errors on quality of laboratory medicine at a neuropsychiatry institute in north India. Indian J Clin Biochem 2010; 26:46-9. [PMID: 22211013 DOI: 10.1007/s12291-010-0082-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2010] [Accepted: 09/24/2010] [Indexed: 10/18/2022]
Abstract
Advances in instrument technology and automation have simplified tasks in laboratory diagnostics reducing errors during analysis thereby improving the quality of test results. However studies show that most laboratory errors occur in the pre-analytical phase. In view of the paucity of studies examining pre-analytical errors, we examined a total of 1513 request forms received at our laboratory during a 3 month period. The forms were scrutinized for the presence of specific parameters to assess the pre-analytical errors affecting the laboratory results. No diagnosis was provided on 61.20% of forms. Type of specimen was not mentioned in 61.60% of the forms and 89.25% of all forms were illegible. Critical results were encountered in 17.30% of patients, and of these 76.60% were not communicated due to incomplete forms. Thus, by following standard operating procedures vigorously from patient preparation to sample processing the laboratory results can be significantly improved without any extra cost.

Abstract
BackgroundLaboratory errors made during the pre-analytical phase can have an impact on clinical care. Quality management tools such as Six Sigma may help improve error rates.AimTo use elements of a Six Sigma model to establish the error rate of test registration onto the laboratory information system (LIS), and to deduce the potential clinical impact of these errors.MethodsIn this retrospective study, test request forms were compared with the tests registered onto the LIS, and all errors were noted before being rectified. The error rate was calculated. The corresponding patient records were then examined to determine the actual outcome, and to deduce the potential clinical impact of the registration errors.ResultsOf the 47 543 tests requested, 72 errors were noted, resulting in an error rate of 0.151%, equating to a sigma score of 4.46. The patient records reviewed indicated that these errors could, in various ways, have impacted on clinical care.ConclusionThis study highlights the clinical effect of errors made during the pre-analytical phase of the laboratory testing process. Reduction of errors may be achieved through implementation of a Six Sigma programme.
