We have aimed at measuring the sensitivity and specificity of the

different adpkd administrative coding algorithms in a clinical population with non-adpkd cysic disease and renal adpkd. We used a dataset of all patients who participated in a clinic of hereditary kidney diseases in Toronto, Ontario, Canada between 1 January 2010 and 23 December 2014. This data set included patients who met our standard definition

of ADPKD or other kidney cystic diseases. We linked this dataset to the health databases in Ontario. We developed eight algorithms to identify ADPKD using the international disease classification, 10th Revision codes (ICD-10) and provincial diagnostic invoicing codes. A patient was considered a positive algorithm if any of the codes in the algorithm

appeared at least once between April 1, 2002 and March 31, 2015. The ICD-10 coding algorithm had a sensitivity of 33.7% [Confidence Interval of 95% (CI) 30.0 € "37.7] and a specificity of 86.2% (95% CI 75.7? 92.5) for the identification of ADPKD. The provincial diagnostic billing code had a sensitivity of 91.1% (95% CI 88.5 "93.1) and a specificity of

10.8% (95% CI 5.3" 20.6) .ICD-10 Encoding can be useful to identify patients with a high probability of having ADPKD but not identifying many patients with ADPKD. Invoicing codes of provincial diagnosis have identified most patients with ADPKD and also with other types of kidney cysic disease. The autosomal dominant policyistic kidney disease

(ADPKD) is characterized by a focal cyst development that leads to the enlargement of both kidneys [1]. It is a relatively uncommon condition with a prevalence of 1 from 1000 to 1 in 400 (0,1 "0,25%) [2]. For this reason, assembling a large cohort of patients with ADPKD for research poses a challenge. One possible way to overcome this challenge is

to use the existing databases and administrative health codes to assemble a group of patients with adpkd.Patients with ADPKD can be acquired by international classification of diseases, 10th review (ICD-10) Codes and Health Insurance of the Ontario PLAN CODICI DI Diagnosi. The International Classification of Diseases, the 9th Review (ICD-9) is an

alphanumeric encoding system developed by the World Health Organization in 1979 to allow the comparability of mortality and morbidity data between countries. In 2002, the ICD-9 codes were replaced by the most complete series of ICD-10 codes in Ontario, Canada. In Canada, the trained staff reviewed the medical charts of each patient with a

hospital meeting on a continuous basis and assigned ICD-9 or ICD-10 codes to each hospital meeting according to the rules and guidelines provided by the Canadian Institute for Health Information (CIHI). These codes include descriptors for ADPKD. Diagnosis codes of opening parts are sent by Ontario doctors to be refunded for the services they

provide. The ohip part diagnosis code for other cystic kidney disease (593) and congenital urinary system abnormalities (753) may also capture patients with ADPKD, but also patients without adpkd.to the main objective of the current study was to determine whether adpkd administrative coding algorithms identify patients with ADPKD and

distinguish them from patients with similar conditions. We must first ensure that adpkd administrative coding algorithms can identify sopatients with ADPKD and distinguish them from patients with similar conditions before using them. To date, two studies have evaluated the performance of ICD-9 and ICD-10 codes related to ADPKD [3]. Both studies

have shown that a high percentage of patients identified with a code for ADPKD had really adpkd (i.e. a high-positive predictive value) [3, 4]. However, these studies have not assessed the sensitivity and specificity of these codes or performanceOHIP diagnosis codes. Calculate sensitivity and specification using a cohort of patients with ADPKDs and

patients with similar conditions provide additional information on the performance of the code. We conducted this study to understand the sensitivity and the specification of different coding algorithms that contain the ICD-10 and OHIP diagnosis codes for ADPKD in a clinical population with different types of cystic renal disease to obtain information

on which percentage of patients with ADPKD They are captured by codes and if administrative codes in Ontario differentiate patients with ADPKD from patients with similar conditions. We have also described and compared the characteristics of patients identified with the different coding algorithms at the time of assigning the code. Materials and

methods Design of the study We conducted a validation study to evaluate the sensitivity and specification of ADPKD coding algorithms using the ICD-10 and OHIP diagnosis codes. We used potential data collected by a hereditary kidney disease clinic connected to health databases hosted at ICES, a non-profit research institute. We conducted and

reported this study in accordance with the standards for reporting precision diagnostic analysis [5]. The Institutional Revision Committee at the University Health Network, Toronto, Ontario, Canada approved this study. The Ethics Research Council at the University Health Network has renounced the need to obtain the consent for the use of data

from all other patients who have not subjected genetic tests. We have obtained the patient's consent for all the people who have undergone genetic tests to use their information for research in general. The use of ICES data for this project has been authorized pursuant to art. 45 of the information protection of information on personal health of

Ontario, which does not require review by a research ethics committee. Reference Standards Our study population included 674 adult patients (¡ë ? 18 years of age) with ADPKD and other types of cystic renal disease that have been seen at the hereditary clinic of kidney disease at the Toronto General Hospital, Toronto, Ontario, Canada between 1

January 2010 and 23 December 2014. The mix of cases seen at the hereditary clinic of kidney disease is patients referred to in the specialtious clinic from other nephrologists of the community. Patients were subjected to abdominal images before visiting the clinic. All patients included in the data set have been tested to renal function to their first

visit. A subset of patients (520 patients) has also undergone a complete mutation screen of PKD1 or PKD2 genes [6, 7]. Details on complete screening methods for mutations in the PKD1 and / or PKD2 gene are reported elsewhere [8]. A senior nephrologist with content experience in ADPKD (YP) judged the ADPKD status of each patient based on if a

PKD1 or PKD2 pathogenic mutation was detected after a complete mutation screen and / or if each patient satisfied or not Chasked diagnostic criteria accepted internationally for ADPKD. The current diagnostic criteria of ADPKD ultrasound are the family history of ADPKD and a specific minimum number of cysts in the kidneys (s) on a conventional

renal ultrasound: (i) three cysts in total when the number of cysts seen in both kidneys they are combined for patients ? ¡è39 years of age; (ii) at least two cysts in each kidney for patients aged between three and 59 years. This gave rise to the ADPKD state variable in the clinic database for hereditary diseases, which served as a reference standard for

this study. Those who have an ADPKD state based on a screen and / or ultrasound images have been categorized as having ADPKD and those with autosomal recessive polycytive renal disease or other cystic diseases have been classified as not having ADPKD. We have also collected and recorded demographic information, such as the name, date of

birth, postal code and sex, as well as the Ontario the Ontario number of paper and number of medical records of each patient to allow data connection. Data sources, patient selection and data collection In the kidneys' hereditary clinic database we have connected patients to five administrative databases held at ICES: (i) CIHI Discharge Abstract

Database (DAD), which contains information on hospital discharges of patients admitted to hospitals in Ontario; (iii) National Ambulatory Care Reporting System (NACRS), which contains information about patients who visited the emergency department; (iii) the OHIP status database, which contains demographic data and vital information. These

data sets have been linked using unique and encoded identifiers and analyzed to ICES. We used the clinic database for hereditary kidney disease to assemble our patient study population with ADPKD and other cystic kidney disease. As a data cleaning phase, we excluded patients who were non-Ontario residents or with missing or invalid identifiers.

We examined in the period from 1 April 2002 to 31 March 2015 to determine whether each patient had at least one ICD-10 code for ADPKD during a hospital meeting using CIHI-DAD and NACRS, or an OHIP Diagnosis Code for ADPKD turnover by a doctor. If a patient had more than one administrative code for ADPKD, we selected the first code and

used it as a date the first time the patient was recognized to have ADPKD using administrative data. We ranked a patient as a positive algorithm if one of the codes appeared at least once. The analyst was not blinded to the ADPKD state. However, the trained medical staff conducted a standardized review of each hospital medical card and assigned

administrative database codes; These staff were not aware of this study. Database algorithms We have identified three ICD-10 and two OHIP diagnostic codes that could be connected to ADPKD (Table 1) and evaluated the diagnostic performance of these codes individually, as well as three combinations of these codes, to identify patients with ADPKD.

Description . CIHI-DAD and NACRS Q611 Polycystic kidney disease, autosomal recessive CIHI-DAD and NACRS Q612 polycystic kidney disease, autosomal dominant CIHI-DAD and NACRS Q613 polycystic kidney disease, OHIP 753 congenital abnormalities, Other kidney disorders or urethra analysis We have calculated sensitivity and specificity for

each of the encoding algorithms and calculated their respective trust intervals of 95% (CI) using the Wilson scoring method [10]. A high sensitivity algorithm classifies a large percentage of patients who really have ADPKD as positive ADPKD. An algorithm with high specificity classifies a large percentage of patients without ADPKD as negative

ADPKD. We have not calculated positive and negative predictive values because these measures are influenced by the prevalence and prevalence of ADPKD in our study population is higher than in the general population. For patients we have identified as having ADPKD with algorithms we have also described the average [standard deformation (SD)]

age, sex, percentage of patients who had the kidney disease at the end of the stage, percentage of patients who were hypertensive and distribution of Johns Hopkins' aggregate diagnosis group (ADG) score at the time of the code assignment. Johns Hopkins' ADG score is a comorbidity score based on the use of the health system that ranges from 0 to

32, where a higher score indicates greater comorbidity (the Johns Hopkins ACG System 10.0) [11, 12]. Among patients with laboratory values, we also haveThe estimated glomerular filtration rate (EGFR) and the chronic phase of renal disease. We conducted all the analyzes using SAS 9.3 (SAS Institute, Institute, NC, USA). Results Data Linkage and

Study People The database of the hereditary clinic of the kidney disease initially contains 674 patients seen at the clinic between 1 January 2010 and 23 December 2014. We have determined the status of ADPKD only through imaging in 154 patients and either Renal imaging that genetic screening in 520 patients. After connection and exclusion, the

final study cohort consisted of 646 patients with cystic renal disease (581 patients with ADPKD and 65 patients with other cystic renal diseases; Figure 1). The average age of patients with ADPKD was 35 (SD 16) and 57% were feminine. The average age of patients with other cystic diseases was 37 (SD 18) and 46.2% were feminine. Open in the new

tab the slide Sensitivity and specifies of the different alternative coding algorithms The sensitivity and specification of each of the five individual administrative codes and the three different coding algorithms are presented in Table 2. In general, sensitivity was high for codes Diagnosis OHIP and relatively low for ICD-10 codes. On the contrary, the

specification was low for OHIP and high diagnosis codes for ICD-10 codes. Encoding algorithm (95% CI),%. Specificness (95% CI),%. ICD-10611 ? ¡ë ¡è0.9 (0.4? € "2.0) to ? ? ? 92.3 (83.2? €" 96.7) The characteristics of the patients identified with the different coding algorithms at the time of the code assignment are presented in Table 3. Patients

identified with any of the OHIP diagnosis codes tended to be more young on average than patients identified with ICD-10 codes related to ADPKD. There were about the same percentages of females in all three groups. Patients identified with ICD-10 codes on average had a greater number of comorbidities than patients identified with OHIP diagnosis

codes. Among those with available laboratory values, renal function (defined by the latest EGFR in 1 year before the code assignment) was also lower in the group identified with ICD-10 codes compared to the group with OHIP diagnosis codes. A higher percentage of patients identified with ICD-10 codes also had end-stage renal disease and were

more likely to be diagnosed with hypertension compared to patients identified with OHIP diagnosis codes. Table 3.
