[Veracity of smokers' reports of abstinence at smoking cessation clinics].

OBJECTIVE: To assess the reliability of smokers' response as criteria for measuring abstinence and the necessity or not of confirming abstinence with carbon monoxide (CO) measurement. PATIENTS AND METHODS: A multicenter, prospective, longitudinal study was carried out on patients over 18 years of age from 5 smoking cessation clinics who underwent treatment with nicotine or bupropion. When the patient attended the clinic at 15, 30, 60, 90, and 180 days, abstinence was checked by self-reporting and expired-air CO levels. Sensitivity, specificity, and positive, negative, and overall predictive value of patient reporting, measured CO levels, and the 2 procedures in combination were calculated. RESULTS: A total of 904 smokers (476 men and 428 women) with a mean (SD) age of 42.51 (10.09) years were enrolled in the study. Of the 904 patients that made up the study population, 820, 776, 687, 719, and 679, respectively, attended the scheduled visits to check abstinence. Self-reported point-prevalence abstinence at 15 days was 74.5% and at 180 days was 57.6% while abstinence determined by expired-air CO was 75.7% and 59.4% respectively. Results according to self-reporting, CO measurement, and the 2 methods in combination were not significantly different (P<.05) at any of the points in time. Neither sensitivity nor specificity showed significant differences in relation to patient variables. CONCLUSION: The reliability of self-reported abstinence from smoking is high. Measurement of CO is therefore not essential, although it could be advisable for motivating patients rather than as a way of confirming abstinence.

[Functional ability and social-care problems of the elderly in the Cáceres health area].

OBJECTIVE: To describe the social environment and to identify the health problems and the functional and mental ability of the elderly in the community. DESIGN: Cross-sectional, observational study by means of a questionnaire. PATIENTS: 228 people over 71 and not living in an institution. SETTING: Cáceres Health Area. MAIN MEASUREMENTS: Questionnaire on social and demographic details, main pathologies, social assessment (Gijón scale), functional assessment (Barthel and Lawton-Brody scales), mental assessment (Pfeiffer test), geriatric problems and visits from health professionals. RESULTS: 67% of the 228 people in the sample were women, with an average age of 79. Comorbidity, present in over 70% of the elderly, was significantly related to multi-medication, falls, hospital admission, depression and insomnia. The most common social and family situation was of a person living with his/her partner (38.3%; CI, 6.31) or children, in a dwelling with architectural barriers (43.0%; CI, 6.43), with a good relationship to his/her social surroundings (61.0%; CI, 6.33). The Barthel test showed a significant relationship with all the geriatric problems declared. The Pfeiffer test showed a relationship with falls (t=3.10; P=.00214), with hearing problems (t=1.98; P=.048), with incontinence (t=3.59; P=.0040) and constipation (t=2.64; P=.0086). The Lawton-Brody test was related, in women, with falls (t=4.27; P=.00034), admissions (t=2.02; P=.044), constipation and sight and hearing problems; and in men, with depression and incontinence. CONCLUSIONS: Elderly people in the Cáceres Health Area showed good functional ability in their basic daily tasks, less ability in instrumental activities and high comorbidity.

Diagnostic performance of arginase activity in colorectal cancer.

Arginase activity was measured in serum and biopsy from healthy individuals and colorectal cancer patients. Arginase activity in tumor samples (87 +/- 7.7 U/g tissue) was significantly higher than in controls (40.7 +/- 3.3 U/g tissue). However, serum arginase activity did not show any significant change in both groups. Finally, the micromethod used to quantify arginase activity in this study is superior to other methods because it has increased sensitivity, requires less sample, and is less time-consuming. Arginase differences are significant, according to the t-test (P<0.05)

[The debate on the organization, functions and efficiency of nursing in primary care: apropos of a qualitative study].

OBJECTIVE: To show the opinions that doctors and nurses express on the organisation and competences of primary care nursing, and on inter-professional relations. DESIGN: Qualitative research study based on the group discussion technique known as Philips 66. SETTING AND PARTICIPANTS: Three discussion groups, one of nurses, one of doctors and a third mixed, with 6 components each, half from Cáceres and the rest from other provinces, and all involved in primary care health delivery. MEASUREMENTS AND MAIN RESULTS: In the discussions, the three groups coincided in the importance given to nursing clinics and home visits, in the organisational advantages that the attachment as a norm of the population to a nursing clinic would bring, in the ability of nurses to perform the techniques they have habitually used, and in defence of one sole clinical record per patient. They blamed each other mutually for making few home visits. Doctors attributed to nurses under-use of records and nurses alleged doctors took no notice of their notes. On the question of their relations, doctors thought that nurses did not take on joint responsibility for the work-loads in health centres; and nurses thought that doctors did not wish to share tasks, but rather delegate or order them. CONCLUSIONS: The attachment of the population to nursing clinics would favour the extension of care, the commitment to the population and the real delivery of services, as well as professional autonomy and recognition.

[The mortality at 2 years in chronic patients confined to home].

OBJECTIVE: To analyse the relationship between the mortality of the chronically ill confined to their homes and the risk of death predicted by the doctor and other variables. DESIGN: Longitudinal descriptive study. PATIENTS: 223 patients were studied over 2 years. MEASUREMENTS AND MAIN RESULTS: Survival was related to the variables measured at the beginning of the follow-up: age, sex, social class, time of confinement, number of diagnoses, hours in bed, evaluation with the Katz index and the Nottingham health profile, number of medicines, family help available, and doctor's opinion on the risk of death. 67% of the patients considered at very serious risk of death died within 6 months, as against 6.91 who died in the same period but had a different prognosis. 40.6% at serious risk died within a year, against 12.4% with a different prognosis. The variables independently associated with higher mortality are: the doctor considering that the risk of death is serious/very serious, OR and 95% CI; 2.57 (1.64-4.03); remaining over 16 hours a day in bed, OR 2.39 (1.31-4.36); being over 80, OR 3.41 (1.74-6.66) and being male, OR 1.61 (1.11-2.33). CONCLUSIONS: The prognostic judgement of the general doctor behaved as a predictor of mortality, and may be an indirect indicator of his/her capacity to foresee the need for health services.

[The frequency of illnesses attended and its relationship with the maintenance of the family doctor's skill].

OBJECTIVE: To describe the incidence of health problems dealt with less often in primary care medical consultations, and to discuss its relationship with the maintenance of professional skill, with in-work training and case-load planning. DESIGN: A prospective observational study based on a year's recording. SETTING: The clinics of 44 primary care doctors from 10 autonomous communities. PATIENTS: 418,98 people were attended. INTERVENTIONS: The unit of analysis was the care episode. The incidence per 1000 people attended, in total and by demographic mean, of the less common health complaints (incidence less than 1/1000) was calculated. RESULTS: Primary care doctors attended at greater frequency than 1/1000 all diseases of eyes, ears, mastoids (except salpingitis) and menstrual disorders codifiable under the classification CIPSAP; almost all the respiratory, skin and locomotive diseases, and more than half of the circulatory, genito-urinary, digestive and endocrine-metabolic diseases. Incidence was less than 1/1000 in all the malignant tumours and contagious diseases, except viral hepatitis and tuberculosis in the urban setting. CONCLUSIONS: Primary care doctors do not often attend certain serious diseases, which are nevertheless present in many differential diagnoses (malignant tumours). This should be borne in mind in the training strategies aimed at maintaining doctor's diagnostic skills.

[Research and the recent evolution of primary health care].

Primary care in Spain has undergone a burgeoning phase in the 80's, followed by a decade of stagnation in the 90's, with little creativity, a routinisation of tasks, and the set up of service port-folios and program-contracts. On the other hand, the recent changes in the orientation of the research promoted by the health administration, in favor of basic research, at the expense of health services research and clinical epidemiology, are in contrast with the importance of primary care as a natural setting for the management of many causal agents and risk factors for health. Despite such limitations, the culture of research has become present in many primary care centres and pharmacies, and primary care research is increasingly present in scientific journals. Nevertheless, it is necessary, also for the case of primary care, to manage research, in differentiated and specific ways, favoring priorization, evaluation and responsibility through flexible organisational formulas and information systems. This should include contracting procedures allowing for at least part-time research, as well as professional career models acknowledging research and teaching activities. Scientific and professional associations in primary care face the challenge of maintaning research projects, of increasing their presence among professionals, of formulating opinions regarding the problems of their sector, as well as of reinforcing their organizational and communication capabilities.
