Chronic obstructive pulmonary disease (COPD) in Spain and the different aspects of its social impact: a multidisciplinary opinion document. REVISTA ESPANOLA DE QUIMIOTERAPIA : PUBLICACION OFICIAL DE LA SOCIEDAD ESPANOLA DE QUIMIOTERAPIA 2020; 33:49-67. [PMID: 31933347 PMCID: PMC6987629 DOI: 10.37201/req/2064.2019] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Revised: 10/24/2019] [Accepted: 12/02/2019] [Indexed: 12/21/2022]
Abstract
Chronic obstructive pulmonary disease (COPD) is one of the most prevalent diseases in the World, and one of the most important causes of mortality and morbidity. In adults 40 years and older, it affects more than 10% of the population and has enormous personal, family and social burden. Tobacco smoking is its main cause, but not the only one, and there is probably a genetic predisposition that increases the risk in some patients. The paradigm of this disease is changing in Spain, with an increase of women that has occurred in recent years. Many of the physio pathological mechanisms of this condition are well known, but the psychological alterations to which it leads, the impact of COPD on relatives and caregivers, the limitation of daily life observed in these patients, and the economic and societal burden that they represent for the health system, are not so well-known. A major problem is the high under-diagnosis, mainly due to difficulties for obtaining, in a systematic way, spirometries in hospitals and health-care centers. For this reason, the Fundación de Ciencias de la Salud and the Spanish National Network Center for Research in Respiratory Diseases (CIBERES) have brought together experts in COPD, patients and their organizations, clinical psychologists, experts in health economics, nurses and journalists to obtain their opinion about COPD in Spain. They also discussed the scientific bibliometrics on COPD that is being carried out from the CIBERES and speculated on the future of this condition. The format of the meeting consisted in the discussion of a series of questions that were addressed by different speakers and discussed until a consensus conclusion was reached.

Therapeutic enquiries about biological agents as a tool to identify safety aspects and patterns of use. Eur J Hosp Pharm 2015; 23:161-165. [PMID: 31156839 DOI: 10.1136/ejhpharm-2015-000770] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2015] [Revised: 09/22/2015] [Accepted: 10/12/2015] [Indexed: 12/12/2022] Open
Abstract
Background Biotechnological agents (BA) are increasingly being used in clinical practice. We aimed to determine, whether enquiries about them to a therapeutic consultation service have also become more frequent, and to describe the information requested in these consultations. Methods We retrospectively reviewed 14 104 therapeutic consultations collected in a computerised database between 2000 and 2014. Enquiries about BA (monoclonal antibodies, fusion proteins or cytokine antagonists) were chosen. Information on the type of BA, underlying condition, type of enquiry and affiliation of the enquirer was retrieved and compared with data from consultations about other agents. Results During the study period, 365 enquiries about 30 different BA were received. Only 4% of them were received before 2004, while 48.8% were received after 2010. Rituximab, infliximab, adalimumab and etanercept were most frequently enquired about. Agent selection (n=184) and/or adverse effects (n=174) were the most frequent reasons for making an enquiry. Most enquiries about an agent selection were made about an off-label use (n=164), mainly for systemic autoimmune diseases (n=61). Over half of the enquiries about adverse effects were about their teratogenic potential (n=96). Enquiries about BA more often requested an opinion (87.7% vs 77.7%) were made by physicians (89.9% vs 76.9%), from a hospital (81.6% vs 44.5%) and regarded a specific patient (87.4% vs 74.5%). Conclusions Therapeutic consultations about BA are increasing. Most of them are related to uncertainties of health professionals regarding any new medicine: their off-label use, actual adverse effects or the teratogenic potential of the involved agents.

Outcomes of off-label drug uses in hospitals: a multicentric prospective study. Eur J Clin Pharmacol 2014; 70:1385-93. [PMID: 25196202 PMCID: PMC4198805 DOI: 10.1007/s00228-014-1746-2] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2014] [Accepted: 08/26/2014] [Indexed: 01/05/2023]
Abstract
PURPOSE The study aims to assess the clinical evidence, outcome and cost of off-label use of medicines in the hospital setting. METHODS A multicentric prospective cohort study of patients treated with off-label medicines was carried out in five tertiary hospitals from May 2011 to May 2012. Information on clinical characteristics of patients, drugs, outcomes and costs was collected. Patients were followed up to 6 months, and information was assessed by reviewing clinical records and interviewing physicians. RESULTS A total of 226 patients were included. The median (interquartile range (IQR)) age of patients was 46 (33-62) years; 59 % were women. Patients had received a median of three previous treatments, and a lack of response (or suboptimal) was the main reason for off-label use (72.1 %). A total of 232 off-label medicines were administered for 102 different indications. The most frequent medicines were rituximab (49; 21.1 %), botulinum toxin (25; 10.7 %) and omalizumab (14; 6.0 %). In 117 (51.8 %) cases, the level of clinical evidence for their use was low. A partial clinical response was observed in 82 patients (36.3 %), complete response in 71 (31.4 %) and stabilization in 11 (4.9 %). A total of 58 (26.5 %) patients had adverse effects, which in 11 (4.9 %) were severe. The median (IQR) cost per patient was 2,943.07 (541.9-5,872.54). CONCLUSIONS There was a high variability of off-label medicines and indications. Although the clinical evidence of off-label medicines was often low, clinical response was observed in many patients with previous multiple treatment failure, but at the expense of some adverse effects and a high cost. Registers of patients would be helpful for clinical decisions, although clinical trials are needed.

Targeting striatal metabotropic glutamate receptor type 5 in Parkinson's disease: bridging molecular studies and clinical trials. CNS & NEUROLOGICAL DISORDERS DRUG TARGETS 2013; 12:1128-1142. [PMID: 24040811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 11/26/2012] [Revised: 01/25/2013] [Accepted: 01/30/2013] [Indexed: 06/02/2023]
Abstract
Metabotropic glutamate (mGlu) receptors are G protein-coupled receptors expressed primarily on neurons and glial cells modulating the effects of glutamatergic neurotransmission. The pharmacological manipulation of these receptors has been postulated to be valuable in the management of some neurological disorders. Accordingly, the targeting of mGlu5 receptors as a therapeutic approach for Parkinson's disease (PD) has been proposed, especially to manage the adverse symptoms associated to chronic treatment with classical PD drugs. Thus, the specific pharmacological blocking of mGlu5 receptors constitutes one of the most attractive non-dopaminergic-based strategies for PD management in general and for the L-DOPA-induced dyskinesia (LID) in particular. Overall, we provide here an update of the current state of the art of these mGlu5 receptor-based approaches that are under clinical study as agents devoted to alleviate PD symptoms.

Prevalence of pain in adults admitted to Catalonian hospitals: A cross-sectional study. Eur J Pain 2012; 10:721-31. [PMID: 16413801 DOI: 10.1016/j.ejpain.2005.11.003] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2005] [Revised: 11/07/2005] [Accepted: 11/24/2005] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To survey the prevalence of pain in patients admitted to different hospitals of Catalonia and to describe which factors are related to pain. METHODS A cross-sectional study was performed in 1675 patients from fifteen hospitals in Catalonia (Spain). Clinical and demographic data, as well as the existence of pain intensity evaluations and analgesic therapy, were obtained from medical charts. Characteristics of pain were given by patients after being interviewed by trained interviewers. The main-outcome measure was the existence of pain (at the interview, in the previous 24h, at the admission and at any time after admission) that was assessed by a visual analogue scale (VAS). The relationship of prevalence of pain to patients' characteristics was carried out by means of a multiple-logistic-regression model with pain presence as the dependent variable of interest. RESULTS A great variability in the prevalence and intensity of pain among different hospitals was observed. At the time of the interview, 48.5% (95% CI: 46.1-50.9%) of the patients had pain and the median VAS was 40mm (range: 10-100mm), and the prevalence of pain during the previous 24h was similar (47.6%; 95% CI: 45.2-50%). At admission, 26.7% (95% CI: 24.6-28.8%) of patients were in pain, whereas 62% (95% CI: 59.7-64.3%) reported having pain at some time during their stay. Pain intensity annotations were absent in 51.3% (95% CI: 47.9-54.7%) of the medical records of the patients with pain. The factors associated with pain were younger age, female gender, presence of surgery, orthopaedic surgery wards, large hospital and prescribed analgesics. CONCLUSION A high prevalence of clinically relevant pain in in-patients was found as well as a great variability according to type of patients, clinical wards and hospitals. This study gives clear evidence of the lack of adequate management of pain in the majority of the hospitals and calls for the implementation of organisational and educational measurements that may settle this epidemic problem.

Analgesic use and pain in the hospital settings. Eur J Clin Pharmacol 2007; 63:619-26. [PMID: 17447056 DOI: 10.1007/s00228-007-0303-7] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2006] [Accepted: 03/20/2007] [Indexed: 10/23/2022]
Abstract
AIM The aim of this study was to assess the analgesic treatment and the prevalence of pain in patients treated with analgesics in hospitals. METHODS Adult patients treated with analgesics were selected from a sample of 1,675 patients in a cross-sectional study carried out in 15 Catalonian hospitals (Spain). Patient characteristics, type of analgesics, treatment schedules, patients' pain intensity and clinical ward and hospital characteristics were assessed. Adherence to analgesic use guidelines was established according to the principles and recommendations of internationally recognised guidelines for pain management. Pain was determined by asking patients about pain intensity by means of a visual analogue scale (VAS). RESULTS Analgesics were prescribed for 1,173 patients (70%; 95% CI: 67.4-72.6), in whom 57% (95% CI: 54.2-59.8) had pain and in whom 30.5% (95% CI: 27.9-33.1) pain intensity was greater than 30 mm. Adherence to analgesic treatment guidelines was judged appropriate in only 26.9% (95% CI: 24.4-29.4%) of all patients. The administered analgesic dose was in the recommended dose range in 42% (95% CI: 54-58) of all analgesics and in 28% (95% CI: 24-32) of opioid analgesics. A minority of patients was treated with a rescue schedule or patient-controlled analgesia (2%; 95% CI: 1.4-2.6). Pain prevalence was higher in those with analgesic treatment that did not adhere to guidelines (63.6%; 95% CI: 60.4-66.8) than in those considered as having appropriate adherence to guidelines (39.3%; 95% CI: 33.8-44.6) (p < 0.001). Adherence to analgesic treatment guidelines was higher in the large hospitals (21%; 95% CI: 18-24) than in medium and small hospitals (13%; 95% CI: 9-16) (p < 0.001). CONCLUSIONS Although analgesic use is high in the hospital settings, adherence to the principles and recommendations of pain guidelines is low, and pain is usually common in patients treated with analgesics. These results once again emphasise the need to improve analgesic use and pain management in hospitals.

Abstract
OBJECTIVE To evaluate the recording of pain intensity in hospital charts. METHODS A cross-sectional study was carried out in 15 hospitals in a sample of admitted patients with pain. Clinical data, including pain intensity, were gathered from the hospital records. Multiple analysis of variance was used to identify factors related to the intensity of pain recorded in the patients' charts. RESULTS A total of 1038 patients with a mean (SD) age of 56.1 (18.9) years were included. Pain intensity was noted in the charts of 47.9% (95% confidence interval [CI], 44.9%-50.9%) of the patients. Pain intensity had been noted for 68.9% (95% CI, 61.4%-76.4%) of the patients with cancer, 43% (95% CI, 38.2%-47.8%) of postoperative patients, 38.2% (95% CI, 35%-41.4%) of trauma patients, and 26.6% (95% CI, 16.9%-36.3%) of postpartum women. There was great interhospital variability. Factors associated with the recording of pain intensity in medical charts were hospital characteristics (large hospitals, teaching hospitals, hospitals and internal medicine and surgical specialities) and type of patient (cancer and trauma cases and patients reporting pain to the staff). CONCLUSION There is inadequate written recording of intensity of pain in hospitals, even though there is considerable interhospital variation. Pain intensity assessment and recording is an indicator of quality of health care and should become a routine practice in hospital health care.

Abstract
OBJECTIVE To assess analgesic drugs in the treatment of postoperative pain after traumatic and orthopaedic surgery (TOS). DESIGN A systematic review of randomised clinical trials (RCTs). DATA SOURCES Electronic PubMed, EMBASE, The Cochrane Library, and hand searches. STUDY SELECTION RCTs of analgesics administered by oral, intramuscular, intravenous, subcutaneous or rectal route, were compared to other analgesics or placebo, in patients under TOS. Study design, characteristics of the study population, analgesic drugs tested, pain intensity and pain relief scores, and adverse effects were assessed. RESULTS Ninety-two RCTs (9,596 patients) met our inclusion criteria. Forty-two (46%) were placebo-controlled, and 50 (54%) were direct comparisons between non-opioid, opioid, and/or combinations of both. Patients' mean age (SD) was 49 years (18). In most trials, gastrointestinal ulcer, liver and renal diseases were exclusion criteria. Only 30 trials (33%) were double-blind and reported standardised outcomes of pain intensity and pain relief; 19 of these were single-dose, and follow up of analgesic effects lasted no more than 12 h in 23 (77%). Globally, only nine trials (10%) were double blind, described dropouts or withdrawals, performed analysis by intention to treat, and reported the effects magnitude. CONCLUSION Evidence from RCTs on the treatment of postoperative pain after TOS is inadequate for clinical decision making. Assessment of analgesics in pain after TOS should be based on agreed clinically relevant outcomes, in representative patients, and for longer observation periods. In addition, it should include direct comparisons between candidate drugs or their combinations and between various drug administration schedules.

Abstract
AIMS/HYPOTHESIS The aim of this study was to compare developments in the utilisation of antihyperglycaemic drugs (AHGDs) in ten European countries. SUBJECTS AND METHODS Data on the yearly utilisation of insulin and oral AHGDs were collected from public registers in Denmark, Finland, Norway, Sweden, Belgium, England, Germany, Italy, Portugal and Spain, and were expressed as defined daily doses per 1,000 inhabitants per day. RESULTS Total AGHD utilisation increased everywhere, but at different rates and levels. Insulin utilisation doubled in England and Germany, but hardly changed in Belgium, Portugal or Italy. Sulfonylurea utilisation doubled in Spain, England and Denmark but was reduced in Germany and Sweden. Metformin utilisation increased greatly everywhere. There were two- to three-fold differences in AHGD utilisation even between neighbouring countries. In Finland, there were more users of both insulin (+120%) and oral AHGDs (+80%) than in Denmark, and the daily oral AHGD doses were higher. In Denmark and Sweden, AHGD utilisation was equal in subjects aged <45 years, but in those >or=45 years of age, both insulin and oral AHGD utilisation were twice as high in Sweden. CONCLUSIONS/INTERPRETATION The ubiquitous increase in AHGD utilisation, particularly metformin, seems logical, considering the increasing prevalence of type 2 diabetes and the results of the UK Prospective Diabetes Study. However, the large differences even between neighbouring countries are more difficult to explain, and suggest different habits and attitudes in terms of screening and management of type 2 diabetes.

Abstract
AIM To describe the opinions of hospital physicians concerning problems regarding the spontaneous reporting of adverse drug reactions (ADRs) and ways to solve them. METHODS A qualitative study was carried out. Fifteen focus groups were conducted among physicians working in a tertiary teaching hospital. A total of 208 physicians from different medical specialities participated. The focus group discussions were recorded by three different observers and the transcripts of each session were analysed for issues and themes emerging from the text. RESULTS Four types of obstacles to spontaneous reporting were considered particularly important: (i) problems with the ADR(S) diagnosis; (ii) problems with the usual workload and lack of time; (iii) problems related to the organization and activities of the pharmacovigilance system; (iv) and problems related to potential conflicts. The potential solutions suggested for improving spontaneous reporting were to define the kind of ADR(S) which should be reported, to facilitate an easy contact and quick access to the hospital pharmacovigilance system, to facilitate information and support for reporting and feedback of pharmacovigilance activities. CONCLUSIONS The perception of the different obstacles by the hospital physicians is an important factor in determining the causes of the underreporting of ADRs and addressing these obstacles could lead to an improvement in spontaneous reporting. A closer relationship between the doctors and the pharmacovigilance centre is suggested as a means of solving these problems. More information is needed to improve the spontaneous reporting of ADR(S) in specialized healthcare.

OBJECTIVE To assess the efficacy of oral drugs in the treatment of spasticity in patients with nonprogressive neurologic disease (NPND). METHODS Systematic review of double-blind randomized controlled trials of antispastic oral drugs in the treatment of spasticity in NPND. DATA SOURCES Electronic MEDLINE, PubMed, Cochrane Library, and hand searches. RESULTS Twelve studies (469 patients) were included (6 on stroke, 3 on spinal cord diseases, and 3 on cerebral palsy). Tizanidine was assessed in four trials (276 patients, 142 exposed), dantrolene in four (103, 93), baclofen in three (70, 55), diazepam in two (127, 76), and gabapentin in one (28, all exposed). Most trials were of small size, of short duration, and their methodologic quality was inadequate. Ten trials were controlled with placebo and only two were direct comparisons between drugs. Efficacy outcome variables were heterogeneous. Only four reports described the magnitude of the antispastic effect. The incidence of adverse drug effects (drowsiness, sedation, and muscle weakness) was high. CONCLUSION Evidence on the efficacy of oral antispastic drugs in NPND is weak and does not include evaluation of patients' quality of life. If any, efficacy is marginal. Adverse drug reactions were common. Better methodologic instruments are needed for the evaluation of antispastic treatment.

Abstract
INTRODUCTION In recent years, new atypical antipsychotic drugs have been marketed. This study aims to analyze the evolution of the consumption pattern and pharmaceutical cost of the antipsychotic drugs during the last years and the impact that the new atypical antipsychotic drugs have had. METHODS Based on the ECOM database of the Ministry of Health and Consumer Affairs of Spain, the sales data of the antipsychotic drugs in Catalonia during the 1990-2001 period have been chosen. The drugs have been classified into typical or classical and atypical. Consumption data have been expressed in daily defined dose (DDD) per 1,000 inhabitants and per day of treatment (DID), and cost data in constant euros. RESULTS Antipsychotic consumption increased from 3.31 DID in 1990 to 6.04 DID in 2001. Typical drugs consumption decreased (from 100 % consumption in 1990 to 46 % in 2001) and that of the atypical ones increased (from 1% consumption in the year 1993 to 54% in the year 2001). A change in the use pattern of different drugs is verified. In the year 1990, the most consumed drugs were flupenthixol (0.86 DID) and haloperidol (0.67 DID), and in the year 2001 olanzapine (1.69 DID) and risperidone (1.30 DID). The drugs with a greater increase in consumption were olanzapine, which multiplied its consumption five fold from 1997 to 2001 and risperidone, which multiplied it by 20 from 1994 to 2001. During the study period, the cost increased 13 times, above all due to increase in cost of atypical antipsychotics (from less than 1 % of the total cost in 1993 to 92 % of the total cost in 2001). The DDD cost of antipsychotics increased (6.48 euros in 1990 and 20.31 euros in 2001). However, that of the typical antipsychotics decreased (6.48 euros in 1990 and 4.62 euros in 2001) and that of the atypical ones increased (2.06 euros in 1993 and 15.69 euros in 2001). CONCLUSION The marketing of the new atypical antipsychotic drugs has had an extraordinary impact on antipsychotic drug consumption and cost. The cost/effectiveness ratio of the new atypical antipsychotic drugs in the clinical practice should be evaluated to determine the economic resources aimed at costs of the different antipsychotic drugs.

Abstract
OBJECTIVE To describe the prescribing patterns and their quality in relation to the prescriber's medical specialty in a defined population. METHODS The study was done on a random sample of all primary care medical prescriptions made through the social security system during 1 year in Andorra, a small European country. Number and type of prescribed medicines, prescribers' medical speciality and patients' age and gender were recorded. Medical specialties considered were General Practice, Paediatrics, Cardiology, Pneumology, Gynaecology, Ophthalmology and Other. A set of various quality indicators [World Health Organisation (WHO)/International Network for Rational Use of Drugs (INRUD) indicators and others] was used. RESULTS The number of medicines prescribed per encounter varied depending on the prescriber's medical specialty and patient's age. Cardiologists and pneumologists tended to prescribe more medicines than other medical specialties. Patients older than 65 years received more prescriptions than younger adults, mostly at the expense of cardiovascular drugs. The contribution of the various groups and subgroups of medicines and the scores of various prescribing indicators showed wide variability across the medical specialties. CONCLUSION Prescribing patterns and indicators of prescription quality show wide variability depending on the prescriber's medical specialty. This has important implications for priority setting in information, continuous education and research.

Abstract
Levofloxacin is a new, recently commercialized fluoroquinolone. We aimed to assess the use of levofloxacin after its inclusion in the hospital drug guide. In a prospective observational study, patients treated with levofloxacin in a university hospital were selected from July 2000 to June 2001. Using a structured questionnaire, data were recorded on patients' demographic characteristics and comorbidities, indications for levofloxacin use and previous use of other antibiotics. In addition, the adherence to the instructions for use as recommended by the antibiotic subcommittee of the hospital, and the use of other alternative antibiotics were analyzed. Ninety-seven patients were treated [mean age 67 years; range 17-93; 64 men], of whom 83 (85.6%) had comorbidity and 51 (52.6%) a possible allergy to the betalactam antibiotics. The treatment began after the use of other antibiotics in 47 (48.5%) patients. The main clinical indications were pneumonia (54; 55.7%) and acute exacerbation of chronic bronchitis (25; 25.8%). The use of other antibiotics was possible in 56 (57.7%) patients, and levofloxacin was only used according to the recommended indications in 41 (42.3%). Levofloxacin is mainly used in the treatment of patients with respiratory infections, those who are allergic to the betalactam antibiotics and those previously treated with other antibiotics; however, in many cases, the use of other antibiotics may still be possible. As part of the antibiotic policy, it is necessary to define the indications of use for new antibiotics introduced in the hospital and surveillance studies need to be developed.

Abstract
OBJECTIVE Postoperative pain is inadequately treated in many surgical settings. The present study evaluates the impact of analgesic drug-use guidelines in the management of postoperative pain. PATIENTS AND METHODS A prospective drug utilization study was carried out in 3 stages in a traumatology, orthopedic and rehabilitation tertiary hospital. The first stage, aimed at describing the patterns of use of analgesic strategies in the management of postoperative pain, identified habits, practices and misconceptions regarding this therapeutic area. After this, an ad hoc representative institutional working group agreed on analgesic drug-use guidelines for the management of postoperative pain. These were then published, presented and discussed with surgeons and nurses. After the guidelines had been implemented, their impact was evaluated in terms of the analgesics used, their dosage and their administration schedule. RESULTS 101 patients were studied before the implementation of the guidelines and 108 patients after. Patients receiving opiate analgesics during the immediate postoperative period increased from 70-94% (p < 0.05). First-choice analgesics used according to the guidelines increased from 40-89% of choices after the implementation of the guidelines (p < 0.05). Administration of analgesics at regular predetermined intervals increased from 45-58% of medical orders, but this increase was not statistically significant (p = 0.07). Prescription of analgesics at adequate doses increased from 67-87% (p < 0.05). CONCLUSION Education on the treatment of postoperative pain is made up of several messages including the drug of choice and dose regimen. Prescribers seemed more receptive to a change in drug rather than issues related to the correct dose regimen. More research is needed to assess how educational activities can improve the management of postoperative pain.

Abstract
OBJECTIVE To describe the variability and appropriateness of antibiotic prescriptions in community-acquired acute respiratory infections (ARI) during childhood in Spain. METHODS A descriptive, multicenter study of variability in clinical practice was conducted by evaluating a prospective series of pediatric patients attending the emergency rooms of 11 Spanish hospitals and diagnosed with community-acquired ARI. The appropriateness of the antibiotic prescriptions was assessed by comparing our clinical practice with consensus guidelines developed for this study. RESULTS We collected data from 6,249 ARI emergencies studied on 30 separate days. Antibiotics were prescribed in 58.7% of the ARI (bronchiolitis, 11.5%; bronchitis, 40.2%; pharyngotonsillitis, 80.9%; nonspecified ARI, 34.8%; pneumonia, 92.4%; otitis, 93.4%; sinusitis, 92.6%). The most commonly used antibiotics were amoxicillin/clavulanate (33.2%), amoxicillin (30.2%), cefuroxime axetil (8.5%) and azithromycin (6%). According to the consensus guidelines developed for this study, therapy was considered to be appropriate in 63.1% of the ARI (first choice, 52.1%; alternative choice, 11.0%) and inappropriate in 36.9%. The percentages of inappropriate prescription according to ARI groups were: bronchiolitis, 11.5%; bronchitis, 31.5%; pharyngotonsillitis, 54.8%; nonspecified ARI, 34.7%; pneumonia, 13.9%; otitis, 25.6%; and sinusitis, 22.2%. CONCLUSIONS There is excessive use of antibiotics in acute respiratory infections that are presumably viral in origin. An important number of ARI of potentially bacterial origin are treated with antibiotics that are not sufficiently efficacious or that have a broader spectrum than necessary.

Abstract
OBJECTIVE This study aims to ascertain the variability in the use of antibiotics for the treatment of acute respiratoryinfections in several hospital emergency services in Spain, as well as the appropriateness of antibiotics prescription through evaluation by a panel of experts using available scientific evidence. METHOD A cross-sectional study was carried out in the emergency services of 10 hospitals in different Spanish regions. We chose patients diagnosed as having acute respiratory infection, aged over 14 years. Among the collected variables were: type of respiratory infection, antibiotic prescription, comorbidity, qualification of the prescribing doctor and hospital admission. The consensus conference held by a panel of experts established first choice treatment and the alternative and inappropriate use for each respiratory infection, based on the available scientific evidence. All the observed prescriptions in our study were classified according to this pattern. RESULTS A sample of 2899 acute respiratory infections was studied (5.5% of all emergencies). Antibacterial agent treatment was prescribed in 82.6% of these, varying according to the infection between 98.5% of pneumonias and 49% of croup-influenza-common cold. The most commonly used antibiotics were amoxicillin-clavulanate and cefuroxime. The global percentage of inappropriate prescription was 40.5% (95% CI; 35.4-45.5). The prescriptions were inappropriate in 16.9% of cases of pharyngotonsillitis, 17.8% of chronic bronchitis, 26.9% of acute bronchitis, 29.3% of pneumonias, 30.8% of otitis and sinusitis and in 70.8% of croup, flu, common cold and non-specified infections. Significant variability among participating centres was observed, both in choice of antibiotics and in their degree of appropriateness. CONCLUSIONS There is excessive use of antimicrobial drugs in acute respiratory infections, and the majority are used for viral infections. There is indiscriminate use of broad spectrum antibiotics, which are valid in some infections but clearly inappropriate in others. Similarly, there are important differences in the choice of antibiotics and their degree of appropriateness among hospitals.

Abstract
We performed a study to evaluate the variability and adequacy of prescribing antibiotics in community-acquired pneumonia (CAP) in 10 Spanish hospitals. We studied 452 patients with CAP. Initial empirical administration of antibiotics was prescribed in 90.7% of the cases, 82.5% as monotherapy. Macrolides and third and second generation cephalosporins were the most widely used groups of antibiotics. Penicillin and amoxicillin were only prescribed in 1. 7% of the patients. A significant variability between hospitals was observed. Reference patterns for the use of antibiotics in CAP were devised by a panel of experts. According to the recommendations of this panel, 29% of the total prescriptions were not adequate, with this percentage reaching 65% in outpatients older than 65 years or with comorbidity. This was mainly due to the fact that monotherapy with erythromycin, which was considered inadequate, was the most widely prescribed treatment.

Abstract
The aim of this study was to investigate the long-term effectiveness and safety of inhaled antibiotic treatment in non-cystic fibrosis patients with bronchiectasis and chronic infection by Pseudomonas aeruginosa, after standard endovenous and oral therapy for long-term control of the infection had failed. After completing a 2-week endovenous antibiotic treatment to stabilize respiratory status, 17 patients were randomly allocated to a 12-month treatment either with inhaled ceftazidime and tobramycin (group A) or a symptomatic treatment (group B). One patient from group A abandoned inhaled treatment because of bronchospasm and another from group B died before the end of the study. The remaining 15 patients, seven from group A and eight from group B, completed the study. Both groups had similar previous characteristics. The number of admissions and days of admission (mean +/- SEM) of group A [0.6 (1.5) and 13.1 (34.8)] were lower than those of group B [2.5 (2.1) and 57.9 (41.8)] (P < 0.05). Forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), PAO2 and PACO2 were similar in the two groups at the end of follow-up, showing a comparable decline in these parameters. There were no significant differences either in the use of oral antibiotics or in the frequency of emergence of antibiotic-resistant bacteria between groups. Microbiological studies suggested that several patients had different Pseudomonas aeruginosa strains. None of the patients presented impaired renal or auditory function at the end of the study. This study suggests that long-term inhaled antibiotic therapy may be safe and lessen disease severity in non-cystic fibrosis patients with bronchiectasis and chronic bronchial infection by Pseudomonas aeruginosa which do not respond satisfactorily to antibiotics administered via other routes.

Abstract
OBJECTIVE Infectious pharyngotonsillitis is usually managed with antibiotics by general practitioners and pediatricians both in primary care and the emergency services. In the present work we try to assess the antibiotic variability and appropriateness in the management of acute pharyngotonsillitis among several emergency services in our country related to scientific evidence based in an expert panel criteria. METHOD A transversal trial was carried on in ten emergency services of our country. We included patients older than fourteen years an analyzed the following variables: type of respiratory infection, antibiotic prescription, comorbidity, physician's status and hospital admission. The antibiotics were classified in three levels according to the expert panel criteria: first election, alternative use and inappropriate use. We compared the antibiotic treatments to these three levels. RESULTS 2,869 patients were diagnosed of acute respiratory infection, 356 (12.4%) with pharyngotonsillitis. Commonly the patients were prescribed antibiotics (315; 81%) and the most used were amoxicillin-clavulanate (33%), amoxicillin (16%), penicillin (7%), cefuroxime (6%), erythromicin (4%) and cefixime (3%). Among the 315 prescriptions, 98 (32%) were first election, 147 (50%) alternative use and 50 (17%) inappropriate use. CONCLUSIONS Most of the patients suffering of pharyngotonsillitis were empirically prescribed antibiotics probably many of these cases were non-bacterial pharyngotonsillitis. Alternative and inappropriate use of antibiotics was high.

Abstract
AIMS Postoperative pain is common in hospital-admitted patients. Its management is determined by different therapeutic traditions and by the attitudes of health professionals in each hospital. The aim of this study was to describe the patterns of prescription and administration of analgesic drugs used for postoperative pain after abdominal surgery in Spanish hospitals, to know the prevalence and the severity of postoperative pain, and to determine the extent of variability in the management of postoperative pain among the participating centres. METHODS The study was a multicentre descriptive cross-sectional drug utilization study in 12 Spanish hospitals. The subjects were an unselected sample of consecutive patients undergoing abdominal surgery, admitted between October 1994 and January 1995. For each patient, information about the surgical procedure and the use of analgesics was prospectively collected. The severity of postoperative pain was assessed during the first day after surgery by means of a six-category (none, mild, moderate, severe, very severe, and unbearable) rating scale and a visual analogue scale (VAS). RESULTS Nine hundred and ninety-three patients (547 men) were included. The most common surgical procedures were inguinal hernia repair (315, 32%), cholecystectomy (268, 27%), appendectomy (140, 14%), bowel resection (137, 14%), and gastric surgery (58, 6%). Fifty-nine percent of patients (587) received nonopioid analgesics only, 9% (89) received opioid analgesics only, and 27% (263) received both opioid and nonopioid analgesics. The most frequently administered drugs were metamizole (667 patients) and pethidine (213 patients). Although in the majority of medical orders the administration of analgesics was scheduled at regular time intervals, the majority of actual doses were given 'as-needed'. The average administered daily doses of all analgesics were lower than those prescribed. Thirty-eight percent (371/967) of patients rated their maximum pain on the first day as severe to unbearable. Wide interhospital variability was recorded in the surgical procedures which had been performed, in the analgesics used, and also in the pain scores referred by patients. The percentage of patients in each centre who suffered severe to unbearable pain varied from 22 to 67%. CONCLUSIONS In Spain many patients still suffer severe pain after abdominal surgery, and this seems to be due to an inadequate use of analgesics. Wide interhospital variability in the management of postoperative pain and in its prevalence was also recorded.

Abstract
BACKGROUND Analgesics can avoid postoperative pain. The aim of this study was to evaluate their prescription after abdominal surgery. PATIENTS AND METHODS Prospective study including patients who had undergone abdominal surgery in two hospitals in Barcelona, in 1993. Prescription and administration of analgesic drugs, and pain severity during the first 48 hours of the postoperative period were evaluated. RESULTS One hundred and sixty-four patients (83 men) were included. The most frequently prescribed drugs were metamizol (111; 68%), pethidine (83, 51%), and diclofenac (44; 27%). A high percentage of analgesic prescriptions on an "as needed" basis was recorded. Administered doses were lower than those recommended, and lower than those prescribed. Fifty-three percent of patients suffered significant pain during the first day. CONCLUSION A too low proportion of analgesic drugs is prescribed in a predetermined schedule, in contrast to "as needed" prescription. Opiate derivatives are underused. All analgesic drugs are prescribed at inadequate dosage. This prescription pattern is associated with a high prevalence of postoperative pain.

Abstract
1. Thromboembolic disease (TED) is an important cause of in-hospital morbidity and mortality. Although different prophylactic approaches have been shown to be effective and cost-effective, surveys have suggested that they are underused. The aim of this study was to estimate the prevalence of use of TED prophylaxis in our hospitals. 2. All patients admitted on a specified day to the Internal Medicine and General Surgery wards of seven Spanish university hospitals were included in the study. They were identified cross-sectionally and followed up until discharge or for 15 days. Information about the following variables was collected: risk factors for venous thromboembolism, prophylactic measures used (if any), contraindications to the use of each specific drug or other prophylactic measure, and dosage schedule of the drug used, if any. 3. Nine hundred and thirty-nine patients (53% men) were studied. The most common risk factors for venous thromboembolism were: age > or = 40 years (802; 85%), major surgery (298; 32%), immobilization > or = 6 days (285; 30%), obesity (241; 26%), and cancer (202; 22%). 4. Prophylactic measures were used in 320 patients (34%). Of these, 297 (93%) received heparin, mainly as low molecular weight heparins (248, 78%); physical measures were rarely used. 5. Five hundred and eighty-three patients (62%) fulfilled criteria for moderate or high risk of venous thromboembolism; only 275 (47%) of them received any form of prophylaxis.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In order to discover the present state of research into the use of medication (UM) in primary care, articles published in the "Original Articles" sections of Medicina Clínica (MC) (Clinical Medicine) and Atención Primaria (AP) (Primary Care) between 1983 and 1990, were studied. A total of 130 articles that meet the definition of the WHO for studies into the use of Medications (SUM) were identified. The instigator and organiser of the research, the drugs included, the kind of study, the source of the data, the main variables used and the qualitative analysis made, were all studied. In conclusion we were able to point out that the characteristics of UM were met in the majority of the studies; although they are the main objective of the study in only a minority of cases. The people who undertook most of the research were those who themselves prescribed the drugs or dealt with very common pathologies. In general, the studies are only descriptive and have a poor level of assessment of the results.

Abstract
BACKGROUND The evaluation of the determination of plasmatic concentrations of theophylline (PCT) in clinical practice is scarce. An observational study was carried out with the aim of discerning the reasons why PCT determinations are requested, the theophyllinemias obtained and the attitude of the medical staff in a hospital. METHODS PCT determinations obtained in 113 patients over a period of 3 months were analyzed. Information concerning treatment and daily doses of theophylline, reasons for theophylline determination, apart from those included in the request for theophyllinemia determination, clinical history and treatment sheets were collected. RESULTS Treatment with theophylline had been indicated in 78 patients (69%) with chronic bronchitis, and 30 (26%) with asthma. All the patients received medication in addition to theophylline. Daily dosage (SD) was 734 (260) mg and the daily doses as to body weight (SD) was 11 (4) mg/kg/day. 188 DNPT were performed, however 22 (12%) were inadequate; of the remaining 166 PCT determinations 117 (69%) had been requested with no indication of insufficient clinical response, suspicion of undesirable effects or modifying factors of the pharmacokinetics of theophylline. The mean plasmatic concentration (SD) was 11.3 (7) micrograms/ml. PCT was infratherapeutic in 74 PCT determinations (44%), therapeutic in 73 (44%) and toxic in 19 (11%). Therapeutic concentrations were obtained in only 16 (35%) of the 45 patients in whom a second PCT determination had been carried out. CONCLUSIONS In this study scarce individualization in the indication of treatment and the doses of theophylline administered are observed. The reason for soliciting determination of theophyllinemia and dosage adjustment in terms of plasmatic concentrations are also commented upon.
