Objectives: Estimate the frequency of erectile dysfunction in patients with essential hypertension and associated variables, degree of control, cardiovascular risk and the impact on quality of life. Material and methods: Type of study: Observational study of prevalence in men with essential hypertension. Measurements: Sociodemographic and comorbidity variables were collected from each patient (age, Charlson index, dyslipidaemia and prostatic hyperplasia), degree of control of essential hypertension and treatment, cardiovascular risk and metabolic syndrome. The erectile dysfunction was diagnosed by the International Index of Erectile Function (IIEF-15). Quality of life questionnaires were carried out in essential hypertension (MINICHAL), and the international scale of prostatic symptoms (IPSS). Results: The study included 262 hypertensive men with an average age of 65.84years. Erectile dysfunction was presented in 46.1%, being severe in 54.9%. The bivariate analysis shows an independent association between erectile dysfunction and the variables: age, Charlon index, dyslipidaemia, benign prostatic hypertrophy, diastolic blood pressure, years of diagnosis of hypertension, number of treatments, Regicor and Framingham-Wilson, glycaemia, creatinine and GPT, glomerular filtration through the MDRD formula, irritative symptomatology (IPSS) and somatic manifestations (MINICHAL). The final multivariate model found association with age, presentation of dyslipidaemia, prostatic hyperplasia and metabolic syndrome. Conclusions: Erectile dysfunction is significantly associated with age, dyslipidaemia, benign prostatic hypertrophy and metabolic syndrome

Effectiveness of an educational intervention to improve the safety culture in primary care: a randomized trial.

BACKGROUND: Fostering a culture of safety is an essential step in ensuring patient safety and quality in primary care. We aimed to evaluate the effectiveness of an educational intervention to improve the safety culture in the family and community medicine teaching units in an Atlantic European Region. METHODS: Randomized study conducted in family and community medicine teaching units in Galicia (Spain). Participants were all fourth-year residents and their tutors (N = 138). Those who agreed to participate were randomized into one of two groups (27 tutors/26 residents in the intervention group, 23 tutors/ 23 residents in the control one).All were sent the Survey on Patient Safety Culture. After that, the intervention group received specific training in safety; they also recorded incidents over 15 days, documented them following a structured approach, and had feedback on their performance. The control group did not receive any action. All participants completed the same survey four months later. Outcome measures were the changes in safety culture as quantified by the results variables of the Survey: Patient Safety Grade and Number of events reported. We conducted bivariate and adjusted analyses for the outcome measures. To explore the influence of participants' demographic characteristics and their evaluation of the 12 dimensions of the safety culture, we fitted a multivariate model for each outcome. RESULTS: Trial followed published protocol. There were 19 drop outs. The groups were comparable in outcome and independent variables at start. The experiment did not have any effect on Patient safety grade (- 0.040) in bivariate analysis. The odds of reporting one to two events increased by 1.14 (0.39-3.35), and by 13.75 (2.41-354.37) the odds of reporting 3 or more events. Different dimensions had significant independent effects on each outcome variable. CONCLUSION: A educational intervention in family and community medicine teaching units may improve the incidents reported. The associations observed among organizational dimensions and outcomes evidence the complexity of patient safety culture measurement and, also, show the paths for improvement. In the future, it would be worthwhile to replicate this study in teaching units from different settings and with different health professionals engaged. TRIAL REGISTRATION: It was retrospectively registered with ( ISRCTN41911128 , 31/12/2010).

Emergency presentation of colorectal patients in Spain.

BACKGROUND: Colorectal cancer (CRC) is the leading cause of cancer deaths in Europe. Survival is poorer in patients admitted to hospitals through the emergency department than in electively admitted patients. Knowledge of factors associated with a cancer diagnosis through presentation at an emergency department may reduce the likelihood of an emergency diagnosis. This study evaluated factors influencing the diagnosis of CRC in the emergency department. METHODS AND FINDINGS: This is a cross-sectional study in 5 Spanish regions; subjects were incident cases of CRC diagnosed in 9 public hospitals, between 2006 and 2008. Data were obtained from patient interviews and primary care and hospital clinical records. We found that approximately 40% of CRC patients first contacted a hospital for CRC through an emergency service. Women were more likely than men to be emergency presenters. The type of symptom associated with emergency presentation differed between patients with colon cancer and those with rectal cancer, in that the frequency of "alarm symptoms" was significantly lower in colon than in rectal cancer patients who initially presented to emergency services. Soon after symptom onset, some patients went to a hospital emergency service, whereas others contacted their GP. Lack of contact with a GP for CRC-related symptoms was consistently related to emergency presentation. Among patients who contacted a GP, a higher number of consultations for CRC symptoms and any referral to outpatient consultations reduced the likelihood of emergency presentation. All diagnostic time intervals were shorter in emergency presenters than in elective patients. CONCLUSIONS: Emergency presenters are not a uniform category and can be divided into categories according to their symptoms, help seeking behavior trajectory and interaction with their GPs. Time constraints for testing and delays in obtaining outpatient appointments led patients to visit a hospital service either on their own or after referral by their GP.

Nomogram and Validity of a Model for Predicting Malnutrition in Patients on Liver Transplant Lists.

BACKGROUND: Malnutrition is associated with increased morbimortality in liver transplant patients, and it is important to identify factors related to nutritional status in these patients. AIMS: Determine variables associated with malnutrition and create a nomogram in liver transplant candidates. METHODS: Cross-sectional study (n = 110). VARIABLES: demographic variables, imbalances due to the disease, transplant aetiology and analytical parameters. Physical examination was performed and degree of hepatic dysfunction calculated. Nutritional status was assessed: Controlling Nutritional Status, Spanish Society of Parenteral and Enteral Nutrition criteria, Nutritional Risk Index, Prognostic Nutritional Index or Onodera Index and The Subjective Global Assessment. Logistic regression analysis was performed. A predictive nomogram (discrimination and calibration analysis) was generated. RESULTS: Malnourishment was defined according to at least 4 or more of the methods studied. Patients with ascites, encephalopathy and portal hypertension presented malnourishment more frequently. Malnutrition was associated with greater liver dysfunction and lower grip strength. Variables independently associated with malnourishment were encephalopathy and lower albumin values. A nomogram was created to predict malnourishment, with good discriminatory power and calibration. CONCLUSIONS: A score was developed for evaluating malnutrition risk. This would provide a tool that makes it possible to quickly and easily identify the risk of malnutrition in liver transplant candidates.

Predictive factors of satisfaction and quality of life after immediate breast reconstruction using the BREAST-Q©.

AIMS AND OBJECTIVES: To analyse quality of life and satisfaction after immediate breast reconstruction due to cancer and its determining factors. BACKGROUND: Studying breast reconstruction is important because of its frequency and variability. In addition to the surgical results, it is necessary to analyse the quality of life and patient satisfaction using a specific tool. DESIGN METHODS: An ambispective design was used (n = 101; α = 0.05; precision = 10%), studying anthropometric, sociocultural data, Fagerström test and the BREAST-Q© questionnaire. A logistic regression analysis was performed to identify variables associated with quality of life and satisfaction. RESULTS: Mean age of the patients on diagnosis was 44.87 ± 8.5 years. Forty-one of the patients were carried out a skin-sparing mastectomy (42.7%). Immediate reconstruction was performed with implant in 73 (74.5%). The domains on the BREAST-Q© for quality of life with the lowest scores were physical well-being chest (74) and sexual well-being (61.5). The satisfaction domain with the lowest score was with the breast (59). The variables associated with the worst quality of life in the physical well-being chest domain were the skin-sparing mastectomy (OR, 4.2; 95% confidence interval (CI), 1.2-14.1) and lymphedema (OR, 12.9; 95% CI, 1.0-159.9). Antibody treatment was associated with a worse score on the psychosocial well-being domain (OR, 4.25; 95% CI, 1.0-18.0) and sexual well-being domain (OR, 7.34; 95% CI, 0.9-54.6). Satisfaction was associated with nicotine dependence on the breast and outcome scale. The higher the dependence on nicotine, the greater the dissatisfaction with the breasts (OR, 2.41; 95% CI, 1.1-5.3) and with the result (OR, 2.45; 95% CI, 1.0-5.9). CONCLUSIONS: The type of treatment and lymphedema modify the patients' quality of life. Nicotine dependence is associated with lower satisfaction with the breast and with the outcome. RELEVANCE TO CLINICAL PRACTICE: This study suggests the need for multidisciplinary attention during the first year of adjuvant treatment despite the benefits of immediate reconstruction. It shows the need for preoperative assessment of the level of nicotine dependence, anxiety and depression of smoking patients before preoperative counselling.

A complexity scale for clinical trials from the perspective of a pharmacy service.

OBJECTIVE: To establish a method for evaluating the complexity of clinical trials (CTs) from the perspective of a pharmacy service (PS) and to analyse the complexity of CTs carried out in a tertiary level hospital. METHODS: An observational, prevalence and retrospective study was carried out in a Spanish tertiary level hospital during the period 2008-2013. A scale of complexity was developed, whose internal consistency was determined by Cronbach's alpha. The study involved five steps: an analysis of the activities involved, score allocation to the activities, identification of CTs started in the study period, data collection and assessment of the complexity. Three complexity levels were determined: low, medium and high. The variables calculated were mean overall complexity, mean complexity per medical specialty, per pathology, per phase of CT, per initiation year and percentage of CTs by complexity level. RESULTS: Cronbach's alpha of the scale of complexity was 0.738. The two most influential items were dose preparation and number of professionals involved. 55.0% of CTs were in the medium level of complexity and 12.1% of CTs were in the high level. The mean complexity of CTs studied was 13.3±4.7 (median 12, range 6-32). Statistically significant differences were found in the complexity values between CTs of different medical specialties, pathologies, phase and dose preparation in the PS (p<0.001). CONCLUSIONS: The scale designed to evaluate the complexity of CTs had internal consistency. More than half of the CTs are in the medium level if complexity. The largest number of CTs with a high level of complexity were in rheumatology and oncology.

Lipid profile, cardiovascular disease and mortality in a Mediterranean high-risk population: The ESCARVAL-RISK study.

INTRODUCTION: The potential impact of targeting different components of an adverse lipid profile in populations with multiple cardiovascular risk factors is not completely clear. This study aims to assess the association between different components of the standard lipid profile with all-cause mortality and hospitalization due to cardiovascular events in a high-risk population. METHODS: This prospective registry included high risk adults over 30 years old free of cardiovascular disease (2008-2012). Diagnosis of hypertension, dyslipidemia or diabetes mellitus was inclusion criterion. Lipid biomarkers were evaluated. Primary endpoints were all-cause mortality and hospital admission due to coronary heart disease or stroke. We estimated adjusted rate ratios (aRR), absolute risk differences and population attributable risk associated with adverse lipid profiles. RESULTS: 51,462 subjects were included with a mean age of 62.6 years (47.6% men). During an average follow-up of 3.2 years, 919 deaths, 1666 hospitalizations for coronary heart disease and 1510 hospitalizations for stroke were recorded. The parameters that showed an increased rate for total mortality, coronary heart disease and stroke hospitalization were, respectively, low HDL-Cholesterol: aRR 1.25, 1.29 and 1.23; high Total/HDL-Cholesterol: aRR 1.22, 1.38 and 1.25; and high Triglycerides/HDL-Cholesterol: aRR 1.21, 1.30, 1.09. The parameters that showed highest population attributable risk (%) were, respectively, low HDL-Cholesterol: 7.70, 11.42, 8.40; high Total/HDL-Cholesterol: 6.55, 12.47, 8.73; and high Triglycerides/HDL-Cholesterol: 8.94, 15.09, 6.92. CONCLUSIONS: In a population with cardiovascular risk factors, HDL-cholesterol, Total/HDL-cholesterol and triglycerides/HDL-cholesterol ratios were associated with a higher population attributable risk for cardiovascular disease compared to other common biomarkers.

Hallux valgus in a random population in Spain and its impact on quality of life and functionality.

The aim of this study was to determine the prevalence of Hallux valgus (HV) and the association between the presence thereof and quality of life, dependence for basic and instrumental activities of daily living and foot function. Prevalence study was carried out in a random population sample (n = 1837) (α = 0.05; Precision = ±2.2%). Informed consent and ethical review board were obtained (code 2008/264). We studied anthropometric variables, Charlson Comorbidity Index, function and state of foot [Foot Function index (FFI), Foot Health Status Questionnaire (FHSQ)], quality of life (SF-36), and dependence for activities of daily living (Barthel and Lawton index). Degree of HV was determined using Manchester scale. Descriptive and multivariate logistic regression analyses were performed. Hence, the prevalence of HV is 39%. Patients with HV are significantly older (64.6 ± 11.7 vs 60.1 ± 12.6 years old). HV prevalence is greater in females (48.1 vs. 28.3%), subjects with flat foot (48.1 vs. 36.1%) or hammer toes (48.2 vs. 30.9%). Moreover, with regard to the presence or not of HV, statistically significant differences were neither noted in the SF-36 questionnaire nor in the Barthel and Lawton Index. For FHSQ and FFI questionnaires, significant differences were observed between patients who presented HV and those who did not. HV is associated with age, gender, flat foot and hammer toes. The SF-36 and Barthel and Lawton questionnaires remained unaltered by the presence of HV. The presence of Hallux valgus was associated with reduced quality of life and increases foot pain, disability and functional limitation.

Variability between Clarke's angle and Chippaux-Smirak index for the diagnosis of flat feet.

BACKGROUND: The measurements used in diagnosing biomechanical pathologies vary greatly. The aim of this study was to determine the concordance between Clarke's angle and Chippaux-Smirak index, and to determine the validity of Clarke's angle using the Chippaux-Smirak index as a reference. METHODS: Observational study in a random population sample (n= 1,002) in A Coruña (Spain). After informed patient consent and ethical review approval, a study was conducted of anthropometric variables, Charlson comorbidity score, and podiatric examination (Clarke's angle and Chippaux-Smirak index). Descriptive analysis and multivariate logistic regression were performed. RESULTS: The prevalence of flat feet, using a podoscope, was 19.0% for the left foot and 18.9% for the right foot, increasing with age. The prevalence of flat feet according to the Chippaux-Smirak index or Clarke's angle increases significantly, reaching 62.0% and 29.7% respectively. The concordance (kappa I) between the indices according to age groups varied between 0.25-0.33 (left foot) and 0.21-0.30 (right foot). The intraclass correlation coefficient (ICC) between the Chippaux-Smirak index and Clarke's angle was -0.445 (left foot) and -0.424 (right foot). After adjusting for age, body mass index (BMI), comorbidity score and gender, the only variable with an independent effect to predict discordance was the BMI (OR= 0.969; 95% CI: 0.940-0.998). CONCLUSION: There is little concordance between the indices studied for the purpose of diagnosing foot arch pathologies. In turn, Clarke's angle has a limited sensitivity in diagnosing flat feet, using the Chippaux-Smirak index as a reference. This discordance decreases with higher BMI values.

INTRODUCCIÓN: Existe una gran variabilidad en las mediciones para el diagnóstico de la patología biomecánica. El objetivo de este estudio fue determinar la concordancia entre el ángulo de Clarke y el índice de Chippaux-Smirak, para determinar la validez del ángulo de Clarke utilizando como referencia el índice de Chippaux-Smirak. MÉTODOS: Se realizó un estudio observacional en una muestra aleatoriamente seleccionada (n=1,002) en A Coruña (España). Tras el consentimiento informado del paciente y la aprobación del comité de ética, se estudiaron variables, antropométricas, índice de comorbilidad de Charlson y un examen podológico (ángulo de Clarke, índice de Chippaux-Smirak). Se realizó un estudio descriptivo y un análisis multivariado de regresión logística. RESULTADOS: La prevalencia de pie plano utilizando el podoscopio fue de 19.0% (pie izquierdo) y 18.9% (pie derecho), incrementándose con la edad.La prevalencia de pie plano según el índice Chippaux-Smirak o el ángulo de Clarke se incrementan considerablemente llegando a 62.0% y 29.7%.La concordancia (kappa I) entre los índices según grupos de edad oscila entre 0.25-0.33 (pie izquierdo) y 0.21-0.30 (pie derecho). El coeficiente de correlación intraclase (CCI) entre el índice de Chippaux-Smirak y el ángulo de Clarke es -0.445 (pie izquierdo) y 0.424 (pie derecho). Tras ajustar por edad, índice de masa corporal (IMC), score de comorbilidad y sexo la única variable con un efecto independiente para predecir discordancia es el IMC (OR= 0.969; IC 95%: 0.940-0.998). CONCLUSIONES: La concordancia entre los índices estudiados para el diagnóstico de la patología del arco plantar es reducida. Existe a su vez una reducida sensibilidad del ángulo de Clarke para el diagnóstico de pie plano, utilizando como referencia el índice de Chippaux-Smirak. Esta discordancia disminuye con valores más altos de IMC.

Flat Foot in a Random Population and its Impact on Quality of Life and Functionality.

INTRODUCTION: Flat foot is a common deformity in adults. It is characterized by medial rotation and plantar flexion of the talus, eversion of the calcaneus, collapsed medial arch and abduction of the forefoot. AIM: The aim of this study was to determine the prevalence of flat foot and its impact on quality of life, dependence, foot pain, disability and functional limitation among random population of 40-year-old and above. MATERIALS AND METHODS: A cross-sectional study in a random population sample from Cambre (A Coruña-Spain) (n=835) was performed (α =0.05; Precision=±3.4%). The diagnosis of flat foot was stablished by the study of the footprint obtained with a pedograph. Anthropometric variables were studied, Charlson's Comorbidity Index, function and state of foot (Foot Function Index (FFI), Foot Health Status Questionnaire (FHSQ)), quality of life (SF-36), and dependence for activities of daily living (Barthel and Lawton index). A logistic and linear multiple regression analysis was performed. RESULTS: The prevalence of flat foot was 26.62%. Patients with flat foot were significantly older (65.73±11.04 vs 61.03±11.45-year-old), showed a higher comorbidity index (0.92±1.49 vs 0.50±0.98), had a greater BMI (31.45±5.55 vs 28.40±4.17) and greater foot size (25.16±1.66 vs 24.82±1.65). The presence of flat foot diminishes the quality of life, as measured by the FHSQ, and foot function, measured by the FFI. The presence of flat foot does not alter the physical and mental dimension of the SF-36 or the degree of dependence. CONCLUSION: Flat foot was associated with age, Charlson's Comorbidity Index, BMI and foot size. The SF-36, Barthel and Lawton questionnaires remained unaltered by the presence of flat foot. The FHSQ and FFI questionnaires did prove to be sensitive to the presence of flat foot in a significant manner.

Negative Pressure Wound Therapy for a Complicated Abdominal Laparotomy in Neonatal Necrotizing Enterocolitis: A Case Report.

Necrotizing enterocolitis (NEC) is the most common surgical emergency in neonatal intensive care units, and patients who require surgery have high mortality and morbidity rates. The utility of negative pressure in the management of adults with complicated abdominal wounds has been documented, but there are few reports describing the use of negative pressure wound therapy (NPWT) in children or following neonatal surgery. The case of a 6 day old, 5-weeks premature neonate with NEC is presented. An exploratory midline laparotomy was performed on day 3 of life owing to rectal bleeding and abdominal distension that did not respond to gastric decompression, bowel rest, and intravenous antibiotics. Ten (10) cm of necrosis in the distal ileum were noted and resected; in addition, an ileostomy was performed, and a Penrose drain was left in the surgical site. On postoperative day 5, the laparotomy dehisced. Continuous NPWT (50 mm Hg) was initiated and changed owing to patient tolerance to intermittent therapy (5 minutes on, 30 seconds off) at 80 mm Hg. By postoperative day 11, granulation tissue formation was complete. No surgical procedures were required for the complete closure of the abdominal wall, and no adverse reactions were noted. The baby was discharged from the hospital on postop day 15. In this patient, the use of negative pressure was found to be safe and facilitated management of a complicated abdominal wound in the presence of a stoma and the formation of healthy granulation tissue. Additional research is needed to help clinicians provide optimal, evidence-based care for dehisced wounds in this vulnerable population.

Concordance among methods of nutritional assessment in patients included on the waiting list for liver transplantation.

BACKGROUND: The aim of the present study was to determine the extent of malnutrition in patients waiting for a liver transplant. The agreement among the methods of nutritional assessment and their diagnostic validity were evaluated. METHODS: Patients on the waiting list for liver transplantation (n = 110) were studied. The variables were: body mass index, analytical parameters, liver disease etiology, and complications. Liver dysfunction was evaluated using the Child-Pugh Scale. Nutritional state was studied using the Controlling Nutritional Status (CONUT), the Spanish Society of Parenteral and Enteral Nutrition (SENPE) criteria, the Nutritional Risk Index (NRI), the Prognostic Nutritional Index (PNI-O), and the Subjective Global Assessment (SGA). Agreement was determined using the Kappa index. Area under receiver operator characteristic curves (AUCs), the Youden index (J), and likelihood ratios were computed. RESULTS: Malnutrition varied depending on the method of evaluation. The highest value was detected using the CONUT (90.9%) and the lowest using the SGA (50.9%). The pairwise agreement among the methods ranged from K = 0.041 to K = 0.826, with an overall agreement of each criteria with the remaining methods between K = 0.093 and K = 0.364. PNI-O was the method with the highest overall agreement. Taking this level of agreement into account, we chose the PNI-O as a benchmark method of comparison. The highest positive likelihood ratio for the diagnosis of malnutrition was obtained from the Nutritional Risk Index (13.56). CONCLUSIONS: Malnutrition prevalence is high and prevalence estimates vary according the method used, with low concordance among methods. PNI-O and NRI are the most consistent methods to identify malnutrition in these patients.

Incidence of cardiovascular events and associated risk factors in kidney transplant patients: a competing risks survival analysis.

BACKGROUND: The high prevalence of cardiovascular risk factors among the renal transplant population accounts for increased mortality. The aim of this study is to determine the incidence of cardiovascular events and factors associated with cardiovascular events in these patients. METHODS: An observational ambispective follow-up study of renal transplant recipients (n = 2029) in the health district of A Coruña (Spain) during the period 1981-2011 was completed. Competing risk survival analysis methods were applied to estimate the cumulative incidence of developing cardiovascular events over time and to identify which characteristics were associated with the risk of these events. Post-transplant cardiovascular events are defined as the presence of myocardial infarction, invasive coronary artery therapy, cerebral vascular events, new-onset angina, congestive heart failure, rhythm disturbances, peripheral vascular disease and cardiovascular disease and death. The cause of death was identified through the medical history and death certificate using ICD9 (390-459, except: 427.5, 435, 446, 459.0). RESULTS: The mean age of patients at the time of transplantation was 47.0 ± 14.2 years; 62% were male. 16.5% had suffered some cardiovascular disease prior to transplantation and 9.7% had suffered a cardiovascular event. The mean follow-up period for the patients with cardiovascular event was 3.5 ± 4.3 years. Applying competing risk methodology, it was observed that the accumulated incidence of the event was 5.0% one year after transplantation, 8.1% after five years, and 11.9% after ten years. After applying multivariate models, the variables with an independent effect for predicting cardiovascular events are: male sex, age of recipient, previous cardiovascular disorders, pre-transplant smoking and post-transplant diabetes. CONCLUSIONS: This study makes it possible to determine in kidney transplant patients, taking into account competitive events, the incidence of post-transplant cardiovascular events and the risk factors of these events. Modifiable risk factors are identified, owing to which, changes in said factors would have a bearing of the incidence of events.

How in-office and ambulatory BP monitoring compare: A systematic review and meta-analysis.

Purpose: We performed a literature review and meta-analysis to ascertain the validity of office blood pressure (BP) measurement in a primary care setting, using ambulatory blood pressure measurement (ABPM) as a benchmark in the monitoring of hypertensive patients receiving treatment. Methods: We conducted a literature search for studies published up to December 2013 that included hypertensive patients receiving treatment in a primary care setting. We compared the mean office BP with readings obtained by ABPM. We summarized the diagnostic accuracy of office BP with respect to ABPM in terms of sensitivity, specificity, and positive and negative likelihood ratios (LR), with a 95% confidence interval (CI). Results: Only 12 studies met the inclusion criteria and contained data to calculate the differences between the means of office and ambulatory BP measurements. Five were suitable for calculating sensitivity, specificity, and likelihood ratios, and 4 contained sufficient extractable data for meta-analysis. Compared with ABPM (thresholds of 140/90 mm Hg for office BP; 130/80 mmHg for ABPM) in diagnosing uncontrolled BP, office BP measurement had a sensitivity of 81.9% (95% CI, 74.8%-87%) and specificity of 41.1% (95% CI, 35.1%-48.4%). Positive LR was 1.35 (95% CI, 1.32-1.38), and the negative LR was 0.44 (95% CI, 0.37-0.53). Conclusion: Likelihood ratios show that isolated BP measurement in the office does not confirm or rule out the presence of poor BP control. Likelihood of underestimating or overestimating BP control is high when relying on in-office BP measurement alone.

Time to diagnosis and stage of symptomatic colorectal cancer determined by three different sources of information: A population based retrospective study.

BACKGROUND: Survival rates from colorectal cancer (CRC) are highly variable in Europe. This variability could potentially be explained by differences in healthcare system delays in diagnosis. However, even when such delays are reduced, the relationship of the diagnostic interval (time from presentation with symptoms to diagnosis) with outcome is uncertain. METHODS: A total of 795 patients with CRC from 5 regions of Spain were retrospectively examined in this population-based multicenter study. Consecutive incident cases of CRC were identified from pathology services. The total diagnostic interval (TDI) was defined as the time from the first presentation with symptoms to diagnosis based on 3 different sources of information: (i) patient-recorded data (PR-TDI) by interview, (ii) hospital-recorded data (HR-TDI), and (iii) general practitioner-recorded data (GPR-TDI). Concordance correlation coefficients (CCCs) were used to estimate the agreement of 3 different TDIs. The TDIs of patients with different stages of CRC were also compared using the Kruskal-Wallis test. RESULTS: The median TDI was 131days based on patient interview data, 91days based on HR data, and 111days based on GPR data. Overall, the agreement of these TDIs was poor (CCCPRvsHR=0.399, CCCPRvsGPR=0.518, CCCHRvsGPR=0.383). Univariate analysis indicated that the TDI was greater in those with less advanced CRC for all 3 methods of calculation, but this association was only statistically significant for the HR-TDI (p=0.021). CONCLUSION: There is no evidence that patients with more advanced CRC have longer TDIs. In fact, we found an inverse relationship between the TDI and CRC stage, an example of the "waiting time paradox". This association may likely be due to the presence of unmeasured confounders as the stage when symptoms appear or the tumour aggressiveness.
