In 1986, The Danish National Board of Health published guidelines for cervical cancer screening. These guidelines recommend organized screening with personal invitations every three years to women in the age group 23-59 years, and in the years to come also invitations to women aged 60-74 years. Five years have now elapsed since publication of these guidelines, and we have therefore studied the present organization of cervical cancer screening in Danish counties. Organized screening programmes are now, medio 1991, running in 11 out of the 16 "counties" (this includes the municipalities of Copenhagen and Frederiksberg). One county follows the national guidelines entirely. Six counties follow these guidelines in general, but they do not invite women over the age of 60 years. In all, 45% of women aged 25-74 years are at present invited for cervical cancer screening in Denmark. Two counties have decided to start organized screening programmes in 1992.
Data from the Danish National Health Service records on activities of each of 146 general practices in the county of North Jutland, Denmark, were studied to determine whether the use of proctoscopy influenced the stage at which cancer of the rectum was recognized. Information for all patients in the county who received the diagnosis of cancer of the rectum was obtained from the Danish Cancer Registry. Proctoscopy was performed significantly more often in partnership practices (96%) than in single practices (81%). The frequency with which the test was used varied from 1 to 107 proctoscopies per general practitioner per year. In the 95 patients with cancer of the rectum, no relationship was found between the stage (Dukes') at the time of diagnosis and work-load, size and activity of practice, or use of proctoscopy.
Based on obligatory notifications from pharmacies to the National Board of Health about prescription of strong analgesics as well as questionnaires to the prescribing doctors, the occurrence and causes of pain requiring strong analgesics outside hospitals were analysed over a period of one month in Denmark in a limited population (480,000), corresponding to nearly 10% of the Danish population. During one month, strong analgesics were prescribed to 0.2 per cent of the population. The commonest acute conditions were back pain (23%) and trauma (17%). The commonest recurrent acute conditions were headache (25%) and angina pectoris (17%). The commonest chronic non-malignant conditions were back pain (29%) and pancreatitis (7%). The commonest malignant conditions were lung cancer (20%) and colorectal cancer (14%). The commonest conditions indicated under the chronic pain syndrome were headache (33%) and back pain (13%). Conditions requiring strong analgesics reflect to some extent the distribution of painful conditions in the general population.

Do various General Practice factors influence the participation rate (PR) in the cytological investigation for preventing cancer of the cervix uteri in counties without systematized screening? This was studied in the county of Aarhus, Denmark, where there are no systematic cytological examinations (CE). We studied a random sample of 2023 women aged 27.5 years to 47.5 years. Essential differences in PR depended on various practice characteristics. Practices with the highest average use of CE services, as counted by the Regional Health Authorities, also had the best PR. The relative chance of being sufficiently examined was almost twice as great among patients in active practices compared with other practices. Furthermore, practices with at least one female practitioner and practices that wanted the introduction of systematic screening had a significantly higher PR. There was a slightly higher PR for patients in large practices. Type of practice, i.e. whether single or partnership, and the individual practitioner's attitude to the efficiency of the present opportunistic screening were not related to the PR. Finally, a slightly lower PR was found among patients in the city of Aarhus, whereas the PR in the major cities of the county as a whole did not differ from the coverage rate in the county in general. It is concluded that the Health Authorities' average figure for CE-use/1000 women in the individual practice is the most significant factor that determines the CE rate for any given patient. Variation in the PR in different practices is unacceptably large if all the women are to receive a uniform CE screening offer.

The two most frequent forms of epidemiological investigation are the cohort study and the case control study, which was reviewed in a previous article. This article examines the most commonly used methods of statistical analysis of these studies applied to the 2 x 2 table.
The informative content of summaries concerning 96 patients in whom the diagnosis of cancer of the breast was established in 1986 in local and regional hospitals in Denmark was investigated. The informative content of the summaries were illustrated by investigation of the extent to which the summaries contained information about the diagnosis, treatment, laboratory investigations, information to the patient and her relatives and information about contact with the general practitioner. In addition, summaries from the regional hospitals were investigated as regards information about the prognosis and the medical and sociomedical therapeutic plan. Information about the diagnosis, treatment, laboratory investigations and the medical therapeutic plans was, as a rule, provided in the summaries. Information about information to the relatives, prognosis and the sociomedical therapeutic plan for follow-up control by the general practitioner was scarcely ever provided in the summaries. Information to the patient was mentioned in less than half of the summaries from local hospitals and in less than 20% of the summaries from regional hospitals. This investigation reveals that the summaries lack valuable information.
In June 1988, a questionnaire was sent to 221 Danish general practitioners chosen at random and to 195 registrars who had applied for postgraduate courses in general medicine. The percentage replies were 83 and 73, respectively. Employing the questionnaire, information was obtained about the doctor's employment of CS on the basis of definite case reports and the doctor's assessment of the certainty of the examination. The investigation revealed that there was a general tendency to freer indications than those officially recommended, that younger women were examined more frequently than recommended, that elderly patients were examined less frequently than recommended and that considerable excessive employment of CS took place in women with condylomata and herpes genitalis. As a rule, the doctors overestimated the reduction in the risk of disease obtained by CS. It is concluded that information from the official authorities concerning employment of CS sent to general practitioners is not satisfactory and that this should be considered in extension of future guidelines about the employment of methods of examination. Precise and effectively distributed information about rationel employment of an examination must be considered to be an important way in which to obtain optimal utilization of resources.
Prescription of psychotropic drugs by general practitioners was registered by means of a multicenter-questionnaire investigation in the County of Arhus. A total of 227 doctors registered 4,180 prescriptions to 3,756 patients during one week. The sex ratio (m/f) was 0.5, calculated not only from the number of prescriptions but also from the defined daily doses (DDD). The frequencies of prescribing increased markedly with age so that for men and women in the age group 70+, these were 188 and 322 DDD/1,000 of the population per 24 hours, respectively. Benzodiazepines constituted 67.3% of all of the prescriptions and 76.9% of the prescribed DDD while neuroleptics constituted 13.6% and 3.9% and antidepressives 9.5% and 7.0%, respectively. Neuroleptics were prescribed in doses of about 1/5 DDD. About 50% of the first prescriptions but only 17% of the renewed prescriptions were undertaken by direct doctor-patient contact in connection with consultations or visits in the home. Prescription of psychotropic drug by general practitioners is estimated to constitute just under 90% of the psychotropic drug in the County of Arhus.
From a multicentre-questionnaire investigation in general practice, the prescription of psychotropic drugs to 3,756 patients is described as regards the object, psychiatric diagnosis and treatment and addiction. Twice as many women as men were prescribed psychotropic drugs but no sex differences of significance were present between the relative distributions of the various objects of prescription. 83-90% of the psychotropic drugs were prescribed as hypnotics or tranquilizers while 9-13% were prescribed for the treatment of psychoses. Two thirds of the psychotropic drugs were prescribed for patients who were considered mentally normal, including those suffering from environmental and psychosocial problems while only 1/3 of the patients had a real psychiatric diagnosis. Between 18 and 81% of the patients for whom psychotropic drugs were prescribed, depending upon the pharmacological group, did not have any real psychiatric illness. In over 50% of the patients, the psychotropic drugs prescribed was the only form of treatment, 17% had received interview treatment from the general practitioner and 17% had received treatment from a specialist in psychiatry or had been admitted to a psychiatric department. Approximately 20% of the patients for whom psychotropic drugs were prescribed were potential or genuine addicts.
