An automated algorithm to preselect patients to be assessed individually in point prevalence surveys for hospital-acquired infections in surgery.

In this pilot study, we evaluate an algorithm that uses predictive clinical and laboratory parameters to differentiate between patients with hospital-acquired infection (HAI) and patients without HAI. Seventy-four percent of the studied population of surgical patients could be reliably (negative predictive value of 98%) excluded from detailed assessment by the infection control practitioner.

The evidence for pharmacologic treatment of neuropathic cancer pain: beneficial and adverse effects.

CONTEXT: The prevalence of neuropathic pain in patients with cancer pain has been estimated to be around 40%. Neuropathic pain may be caused by tumor invasion and is considered as mixed nociceptive-neuropathic pain, or caused by an anticancer treatment and considered as purely neuropathic pain. The use of adjuvant analgesics in patients with cancer is usually extrapolated from their efficacy in nononcological neuropathic pain syndromes. OBJECTIVES: In this systematic review, we sought to evaluate the evidence for the beneficial and adverse effects of pharmacologic treatment of neuropathic cancer pain. METHODS: A systematic review of the literature in PubMed and Embase was performed. Primary outcome measures were absolute risk benefit (ARB), defined as the number of patients with a defined degree of pain relief divided by the total number of patients in the treatment group, and absolute risk harm (ARH), defined as the fraction of patients who dropped out as a result of adverse effects. RESULTS: We identified 30 articles that fulfilled our inclusion criteria. Overall, ARB of antidepressants, anticonvulsants, other adjuvant analgesics, or opioids greatly outweighed ARH. There were no significant differences in ARB or ARH between the four groups of medication or between patients with mixed vs. purely neuropathic pain. Because of the low methodological quality of the studies, we could not draw conclusions about the true treatment effect size of the four groups of medications. CONCLUSION: Once a diagnosis of neuropathic pain has been established in patients with cancer, antidepressants, anticonvulsants, or other adjuvant analgesics should be considered in addition to or instead of opioids.

Electronic alerts versus on-demand decision support to improve dyslipidemia treatment: a cluster randomized controlled trial.

BACKGROUND: Indirect evidence shows that alerting users with clinical decision support systems seems to change behavior more than requiring users to actively initiate the system. However, randomized trials comparing these methods in a clinical setting are lacking. We studied the effect of both alerting and on-demand decision support with respect to screening and treatment of dyslipidemia based on the guidelines of the Dutch College of General Practitioners. METHODS AND RESULTS: In a clustered randomized trial design, 38 Dutch general practices (77 physicians) and 87,886 of their patients (39,433 men 18 to 70 years of age and 48,453 women 18 to 75 years of age) who used the ELIAS electronic health record participated. Each practice was assigned to receive alerts, on-demand support, or no intervention. We measured the percentage of patients screened and treated after 12 months of follow-up. In the alerting group, 65% of the patients requiring screening were screened (relative risk versus control=1.76; 95% confidence interval, 1.41 to 2.20) compared with 35% of patients in the on-demand group (relative risk versus control=1.28; 95% confidence interval, 0.98 to 1.68) and 25% of patients in the control group. In the alerting group, 66% of patients requiring treatment were treated (relative risk versus control=1.40; 95% confidence interval, 1.15 to 1.70) compared with 40% of patients (relative risk versus control=1.19; 95% confidence interval, 0.94 to 1.50) in the on-demand group and 36% of patients in the control group. CONCLUSIONS: The alerting version of the clinical decision support systems significantly improved screening and treatment performance for dyslipidemia by general practitioners.

Impact on quality of life of a telemedicine system supporting head and neck cancer patients: a controlled trial during the postoperative period at home.

OBJECTIVES: Telemedicine applications carry the potential to enhance the quality of life of patients, but studies evaluating telemedicine applications are still scarce. The evidence regarding the effectiveness of telemedicine is limited and not yet conclusive. This study investigated whether telemedicine could be beneficial to the quality of life of cancer patients. DESIGN AND MEASUREMENTS: Between 1999 and 2002, we conducted a prospective controlled trial evaluating the effects of a telemedicine application on the quality of life of patients with cancer involving the head and neck, using quality of life questionnaires that covered 22 quality of life parameters. All patients had undergone surgery for head and neck cancer at the Erasmus MC, a tertiary university hospital in The Netherlands. Patients in the intervention group were given access to an electronic health information support system for a period of six weeks, starting at discharge from the hospital. RESULTS: In total, we included 145 patients in the control group and 39 in the intervention group. At 6 weeks, the end of the intervention, the intervention group had significantly improved QoL in 5 of the 22 studied parameters. Only one of these five quality of life parameters remained significantly different at 12 weeks. CONCLUSIONS: This study adds to the sparse evidence that telemedicine may be beneficial for the quality of life of cancer patients.

Cross-sectional analysis of guidelines on cardiovascular disease risk factors: going to meet the inconsistencies.

OBJECTIVE: To identify the possible inconsistency of statements among the practice guidelines of the Dutch College of General Practitioners (DCGP) with respect to the management of risk factors for cardiovascular disease (CVD). METHODS: Cross-sectional analysis of all electronically available DCGP practice guidelines dealing with CVD risk factor management for statement inconsistencies and reference inconsistencies. RESULTS: Six DCGP guidelines out of 74 electronically available guidelines had either CVD or CVD risk factors as the subject of the guideline. Eight statement inconsistencies-were found, and for each statement inconsistency, a reference inconsistency was present. CONCLUSIONS: Given that inconsistencies were found, the authors recommend that organizations that maintain a set of guidelines update the guidelines using a cross-sectional analysis of guidelines. Inconsistencies between guidelines might lead to physicians being unintentionally noncompliant with guideline recommendations.

Quality of life during the first 3 months following discharge after surgery for head and neck cancer: prospective evaluation.

OBJECTIVE: To identify patient groups that are prone to poorer quality of life (QoL) during the first 3 months following discharge from the hospital after surgery for head and neck cancer. DESIGN: Prospective evaluation of the QoL of surgically treated head and neck cancer patients measured with questionnaires at discharge and at 6 weeks and 3 months after discharge. SETTING: Department of Otolaryngology and Head and Neck Surgery of the Erasmus University Medical Centre, a tertiary health care centre in Rotterdam, The Netherlands. PARTICIPANTS: Ninety head and neck cancer patients who had undergone a total laryngectomy, neck dissection, or the commando procedure. MAIN OUTCOME MEASURES: Patients' quality of life in 22 different dimensions. RESULTS: Three patient characteristics associated with poorer QoL during the first 3 months following discharge from the hospital after surgery for head and neck cancer: laryngectomy, lower levels of education, and being single. QoL already improved in eight QoL dimensions during the first 3 months after discharge, but QoL in the dimensions "loss of control" and "physical self-efficacy" worsened during this same period. CONCLUSIONS: It is possible to identify patient groups that are prone to poorer QoL during the first 3 months following discharge from the hospital after surgery for head and neck cancer. The results of this study may help care providers working with head and neck cancer patients to tailor their rehabilitation programs.

Identification of the four conventional cardiovascular disease risk factors by Dutch general practitioners.

BACKGROUND: Detecting and managing the four major conventional risk factors, smoking, hypertension, diabetes mellitus, and hypercholesterolemia, is pivotal in the primary and secondary prevention of cardiovascular disease (CVD). OBJECTIVE: To assess the preventive activities of general practitioners (GPs) regarding the four conventional risk factors and the associated measurements for cardiovascular risk factors by GPs in relation to the time of the first clinical presence of CVD. SETTING: Large longitudinal general practice research database (the Integrated Primary Care Information database) in the Netherlands from September 1999 to August 2003. PARTICIPANTS AND METHODS: Patients > 18 year of age with newly diagnosed CVD with a valid history of at least 1 year before and after the first clinical diagnosis of CVD. Details on conventional risk factors and associated measurements for the four cardiovascular risk factors were assessed in relation to the first clinical diagnosis of CVD. RESULTS: In total, 157,716 patients met the study inclusion criteria. Of the 2,594 patients with newly diagnosed CVD, at least one of the four investigated risk factors was observed in 76% of women and 73% of men. In 40% of cases, no risk factor was recorded before the date of the first CVD diagnosis. In 16% of cases, no associated measurements were present before the first CVD diagnosis. CONCLUSION: In daily practice, GPs seem to focus on the secondary prevention of CVD. Intervention strategies that aim to influence GPs' case finding behavior should focus on increasing the awareness of physicians in performing risk factor-associated measurements in patients who are eligible for the primary prevention of CVD. Further research will have to show the feasibility and effectiveness of such intervention strategies.

Involving the patient: a prospective study on use, appreciation and effectiveness of an information system in head and neck cancer care.

OBJECTIVE: To determine use, appreciation and effectiveness of an electronic health information support system in head and neck (H&N) cancer care. DESIGN: A prospective evaluation study. The evaluated system has four different functions: (1) communication amongst health care providers and between health care providers and patients, (2) information for health care providers and patients, (3) contact with fellow sufferers and (4) monitoring of discharged patients by means of electronic questionnaires. Evaluation of the system was done both objectively using automatically created log files and stored messages, and subjectively by using paper questionnaires from patients and general practitioners (GPs). SETTING: Department of Otorhinolaryngology and Head and Neck Surgery of a tertiary health care centre in the Netherlands. The system was put at patients' disposal for a period of 6 weeks following discharge from the hospital after surgery for H&N cancer, and was additional to standard care. PARTICIPANTS: Head and neck cancer patients, hospital physicians, members of a hospital-based support team, GPs, district nurses and speech therapists. MAIN OUTCOME MEASURES: Actual use of the system by patients and health care providers. Patients' appreciation for each of the system's four different functions. GPs' appreciation for the system. Capability to detect potential patient problems with the system. RESULTS: The system was used by 36 H&N cancer patients, 10 hospital physicians, 2 members of the support team, 8 GPs, 2 district nurses and 2 speech therapists. The total number of patient-sessions was 982: an average of 27.3 sessions per patient during the 6 weeks study period. In total, 456 monitoring questionnaires were completed. The support team in hospital responded with 231 actions. In 16 cases, an extra appointment was made for a patient with the hospital physician. Out of these cases, immediate action was considered necessary eight times. Patients appreciated the system highly, rating it with an average score of 8.0 on a 10-point scale. All patients used the monitoring function, and rated 'monitoring' with a mean score of 8.0 on a 10-point scale. Least used and appreciated was the 'contact with fellow sufferers' function. Only 8 out of possible 36 GPs used the system, rating it with an average of 5.6 on a 10-point scale. CONCLUSIONS: The electronic health information support system was used intensively and highly appreciated by H&N cancer patients. The system enabled the early detection of occurring health problems that required direct intervention. ICT can play an additional role in the management of patients, also in a relatively elderly and computer illiterate patient population.

Internet-administered adolescent health questionnaires compared with a paper version in a randomized study.

PURPOSE: To assess whether the scores of an Internet-administered adolescent health questionnaire (using two different interfaces) are equivalent to those obtained via paper and pencil (P&P). Furthermore, it compares adolescents' evaluations of modes of administration. METHODS: We randomly assigned 591 adolescents (aged 13-17 years) from five secondary schools within their classes to one of the two Internet interfaces (multiple items vs. one item per screen) or P&P. Adolescents completed questionnaires on psychosocial well-being (KIVPA), self-reported problems, health care utilization, and health-related behavior and supplementary evaluation surveys (on the given health questionnaire mode) in the computer classrooms. Differences in questionnaire scores among administration modes were analyzed by the Student's t-test and Wald test. RESULTS: Response rate was 96% (n = 565). Adolescents in the Internet one-item mode more frequently reported satisfaction with appearance compared with the Internet multiple-items mode (p

User requirements rating and knowledge-level of general practitioners at the start of CholGate - a lipid management decision support project.

In the CholGate project we performed a preliminary study evaluating user requirements and knowledge level on lipid management in 40 primary care practices in The Netherlands. Practitioners rated speed, usability and completeness as important. We hope to show that the knowledge level of physicians regarding lipid management can be passively increased from its current levels by an integrated decision support system.

An extra letter, care gets better? Informing general practitioners about planned surgery for head and neck cancer.

OBJECTIVE: To investigate how general practitioners (GPs) value an additional letter from the hospital. This so-called preadmission letter informs the GP about planned surgery for head and neck cancer in one of their patients. DESIGN: Prospective survey among GPs by means of a questionnaire attached to the preadmission letter. SETTING: Department of Otolaryngology and Head and Neck Surgery of a tertiary care centre in the Netherlands and 104 different GPs in primary care. PARTICIPANTS: All GPs of patients undergoing surgery for head and neck cancer received the preadmission letter during a 1-year study period. MAIN OUTCOME MEASURES: GPs' appreciation of the received preadmission letter, GPs' opinion on the content of the preadmission letter, and GPs' general opinion on information provided by our hospital. RESULTS: Of the 145 preadmission letters sent during the study year, 115 questionnaires were returned (response rate of 79%). All GPs positively appreciated receiving the preadmission letter and considered its content relevant. They valued the letter, with a mean mark of 8.3 on a 10-point scale. The majority of the GPs agreed that the preadmission letter allows them to provide better care. CONCLUSIONS: GPs highly appreciate an extra letter informing them about intended surgery for head and neck cancer in one of their patients. Despite the basic content of the preadmission letter (five items only), the majority of GPs consider the information sufficient. The results of this study have led to the implementation of the preadmission letter to GPs of head and neck cancer patients on a permanent basis in our institution.

An information system to support the care for head and neck cancer patients.

The potential of Information and communication technology (ICT) as a method to improve care is widely acknowledged. However, before ICT can be used in a specific patient population, the needs of that population must first be made explicit. In this paper we aim to explore the feasibility and functionality of an electronic information system to support head and neck (H&N) cancer care. We describe communication and information bottlenecks in supportive care for H&N cancer patients. These bottlenecks were used to determine the functionality of an electronic health information support system. We discern three perspectives of problems in H&N cancer care: lacking communication among professionals, lacking information about the disease and its treatment, and lacking supportive measures to reduce uncertainty and fear in patients. To support care, an information support system can facilitate (1). communication among all professionals involved and between professionals and patients, (2). professionals' and patients' access to information, (3). contact with fellow sufferers, and (4). early detection of patient problems by means of monitoring. Based on these analyses we subsequently built such a system and established a setting for evaluation. Information and communication technology can be tailored to address the communication and information bottlenecks in supportive H&N cancer care. As we aim to investigate whether care for H&N cancer patients may benefit from ICT, we are currently performing a clinical evaluation study.

Automated and on-demand decision support systems integrated into an electronic medical record have proven to be an effective implementation strategy for guidelines. Cholgate is a randomized controlled trial comparing the effect of automated and on-demand decision support on the management of cardiovascular disease factors in primary care.

Cirgen: sistema Automatizado para las Normas Quirúrgicas de Diagnóstico y Tratamiento / Cirgen: development of a Surgical Guidelines System

Hace más de 30 años fueron introducidas las Normas Cubanas para el Diagnóstico y Tratamiento en Cirugía como instrumento para mejorar la calidad de la atención médica. Con el transcurso de los años algunas dificultades se han presentado y han provocado su uso infrecuente en la práctica quirúrgica diaria, quedando solo para fines educativos. En este estudio proponemos un nuevo formato organizativo para las normas donde se aplica una estructura formal para el contenido de la edición vigente tomando como punto de partida para este prototipo, tres problemas médicos: Enfermedades quirúrgicas del tiroides, Litiasis vesicular y Hernia Inguinal. Se diseñó una base de datos relacional para almacenar la información y se construyó una interface en Hypertext Markup Language (HTML) para permitir una fácil interacción con los usuarios; se incluyeron aditamentos especiales para permitir un rápido acceso a los contenidos del programa y además se agregaron nuevas opciones para consulta de información técnica ampliada, imágenes didácticas y soporte bibliográfico. Con el propósito de lograr una mayor integración a la práctica quirúrgica diaria el sistema se complementa con una aplicación que permite la generación automática de informes quirúrgicos en el momento de la operación. Esta aplicación fue diseñada para un ambiente Windows; utiliza una interface de fácil manejo con un formato similar al informe tradicional que se basa en la información de las normas. Este nuevo instrumento permitirá contar con informes legibles, organizados, completos y almacenados en formato electrónico, a la vez que optimiza el tiempo en el salón y suministra información inmediata sobre el proceder. Para la evaluación clínica del prototipo se propone su aplicación de forma local y a pequeña escala(AU)
