Patient-clinician agreement on signs and symptoms of 'strep throat': a MetroNet study

BACKGROUND: Despite substantial use of the telephone in health care, only a few studies have formally evaluated the appropriateness of telephone-based management for acute medical problems. The accuracy of patients' report of signs and symptoms remains unknown. OBJECTIVE: We compared the agreement between patient self-assessment and clinician assessment on the typical signs and symptoms of group A beta-haemolytic Streptococcus (GABHS) to investigate the potential difficulties of using patient self-report to triage sore throat patients. METHODS: In this cross-sectional study, each of 200 adult pharyngitis patients was instructed to examine him/herself and to record the symptoms and physical findings. Two clinicians independently interviewed and examined each patient and recorded their findings. Each patient then had a rapid GABHS antigen test, the results of which were blinded to both clinicians and patients. Each patient self-assessment was compared with the findings of each clinician, and the agreement and disagreement between them computed. RESULTS: We found varying levels of agreement (kappa=-0.05 to 0.71) between patients and clinicians on sore throat history and physical assessments. Importantly, there was fair to substantial agreement (kappa=0.20-0.71) on the key signs and symptoms used in GABHS clinical prediction rules. As expected, history items had the highest agreement (kappa=0.52-0.71). Patients were more likely than clinicians to report rather than deny a specific physical sign. CONCLUSION: Adult sore throat patients may reliably report their symptoms, but may not be able to assess and report accurately on relevant physical signs of pharyngitis. Patients have a tendency to over-report physical signs. This study indicates the potential difficulties associated with telephone triage of sore throat patients, or other illnesses that require assessment of physical signs.     

Assessing family history of heart disease in primary care consultations: a qualitative study

BACKGROUND: Current primary prevention guidelines recommend the assessment of family history of coronary heart disease (CHD) to identify at-risk individuals. OBJECTIVE: To examine how clinicians and patients understand and communicate family history in the context of CHD risk assessment in primary care. METHODS: A qualitative study. Patients completed a validated family history questionnaire. Consultations with clinicians were video recorded, and semi-structured interviews conducted with patients after consultation. The participants were 21 primary care patients and seven primary care clinicians (two practice nurses, five GPs). Four practices in South West England. RESULTS: Patients and clinicians usually agreed about the patient's level of risk and how to reduce it. Patients were mostly satisfied with their consultations and having their family history assessed. However, three issues were identified from the consultations which contributed to concerns and unanswered questions for patients. Problems arose when there were few modifiable risk factors to address. Firstly, patients' explanations of their family history were not explored in the consultation. Secondly, the relationship between the patient's family history and their other risk factors, such as smoking or cholesterol, was rarely discussed. Thirdly, clinicians did not explain the integration of family history into the patient's overall cardiovascular disease risk. CONCLUSIONS: Clinicians appeared to lack a rhetoric to discuss family history, in terms of capturing both genetic and environmental factors and its relation to other risk factors. This created uncertainties for patients and carries potential clinical and social implications. There is a need for better guidance for primary care clinicians about family history assessment.     

Effect of antibiotics on vulvovaginal candidiasis: a MetroNet study

PURPOSE: Vulvovaginal candidiasis (VVC) is believed common after systemic antibiotic therapy, yet few studies demonstrate this association. In this pilot study, we evaluate the effect of short-course oral antibiotic use on VVC. METHODS: Nonpregnant women aged 18 to 64 years who required >or=3 days oral antibiotics for nongynecological diseases were recruited from a family medicine office. Age-matched (+/-5 years) women seen in the same clinic for noninfectious problems were recruited as controls. The main outcomes are incidence of symptomatic VVC and prevalence of positive vaginal Candida culture 4 to 6 weeks after antibiotics. RESULTS: Eighty (44 in antibiotic group) women were recruited; 14 of 79 (95% CI, 0.11-0.28) had asymptomatic vaginal Candida cultures positive at baseline. During follow-up, 10 of 27 (95% CI, 0.22-0.56) women in antibiotic group were Candida culture positive. In contrast, 3 of 27 (95% CI, 0.04-0.28) women in the control group were Candida culture positive (relative risk, 3.33; P = .03). Meanwhile, 6 of 27 (95% CI, 0.11-0.41) women in antibiotic group developed symptomatic VVC whereas none (95% CI, 0-0.12) of the women in the control group developed vaginal symptoms (relative risk, infinity; P = .02). Baseline Candida culture did not predict subsequent symptomatic VVC after antibiotics. CONCLUSION: In this pilot study, the use of short courses of oral antibiotics seems to increase prevalence of asymptomatic vaginal Candida colonization and incidence of symptomatic VVC. Larger cohort studies are needed to confirm these findings.     

Physical health care of patients with schizophrenia in primary care: a comparative study

BACKGROUND: Excess morbidity and mortality associated with schizophrenia is well established. Despite this, no previous multi-centre study has investigated whether patients with schizophrenia receive equitable physical healthcare within primary care. OBJECTIVE: To determine whether patients with a diagnosis of schizophrenia receive the same levels of physical health care from primary care practitioners as patients without schizophrenia. METHODS: Design: Case-matched retrospective case note review. Setting: Twenty-two general practices in the Birmingham area (UK). Subjects: 195 patients with a diagnosis of schizophrenia, 390 matched controls with a diagnosis of asthma and 390 general control patients. Main outcome measures: Proportions of patients within each group having received six pre-defined routine health checks in a 3 year period. Conditional logistic regression models were used to identify differences between groups. RESULTS: Patients with schizophrenia were half as likely as asthma controls to have blood pressure and cholesterol levels recorded (odds ratio 0.51; 95% confidence interval (CI) 1.35-0.73 and 0.50; 0.31-0.82, respectively) and were also less likely to have smoking status noted (0.60; 0.41-0.85). Similarly, patients with schizophrenia were significantly less likely than general population controls to have either blood pressure or cholesterol recorded (0.68; 0.47-0.97 and 0.58; 0.35-0.95). The significant differences observed were maintained after adjusting for potential confounders with the exception of cholesterol recording between the asthma and schizophrenia groups (0.57; 0.30-1.05). CONCLUSIONS: Patients with a diagnosis of schizophrenia are less likely to receive some important general health checks than patients without schizophrenia.     

Primary care of overweight children: the importance of parent weight and attitudes about overweight: a MetroNet study.

PURPOSE: The purpose of this study was to identify the association of parents' weight and attitude about their child's weight with the child's body mass index (BMI) status. DESIGN: Cross-sectional, clinic-based study in a practice-based research network. METHODS: One hundred seventy-one parents or adults accompanying children aged 5 to 17 years to a primary care visit in 4 family medicine centers completed a questionnaire. Parent/adult overweight status and attitudes were compared with child overweight status. RESULTS: Forty-eight percent of children were overweight or obese (BMI >or= the 85th percentile) as were 56% of mothers and 77% of fathers (BMI >or= 25 kg/m(2)). Child and parent overweight were significantly associated, as were mother overweight and beliefs about child overweight status. Children aged 5 to 13 years were more likely to be overweight than those aged >or=14 years. CONCLUSIONS: Parents of overweight children are often overweight and many do not recognize that their children are overweight. Suggestions are made for primary care physicians to engage parents of overweight children in family weight control efforts.     

Studies of symptoms in primary care

Publications on the frequency of defined symptoms in the practice setting, underlying conditions and prognosis have been rare in the past. Also, studies addressing these questions have suffered from several methodological problems. We therefore developed criteria to help investigators improve the quality of study design, implementation and publication. Studies evaluating symptoms in practice can make an important contribution to a more rational approach to diagnostic decision making especially in primary care.     

Investigation of a severity-based classification of mood and anxiety symptoms in primary care patients

BACKGROUND: Current Diagnostic and Statistical Manual of Mental Disorders (DSM) classifications describe spectrums of symptoms that define mood and anxiety disorders. These DSM classifications have been applied to primary care populations to establish the frequency of these disorders in primary care. DSM classifications, however, might not adequately describe the underlying or natural groupings of mood and anxiety symptoms in primary care. This study explores common clusters of mood and anxiety symptoms and their severity while exploring the degree of cluster congruency with current DSM classification schemes. We also evaluate how well the groupings derived from these different classifying methods explain differences in patients' health-related quality of life. METHODS: Study design was cross-sectional, using a sample of 1333 adult primary care patients attending a university-based family medicine clinic. We applied cluster analysis to responses on a 15-item instrument measuring symptoms of mood and anxiety and their severity. We used the PRIME-MD to determine the presence of DSM-III-R disorders. The SF-36 Health Survey was used to assess health-related quality of life. RESULTS: Cluster analysis produced four groups of patients different from groupings based on the DSM. These four groups differed from each other on sociodemographic indicators, health-related quality of life, and frequency of DSM disorders. Cluster membership was associated in three of four clusters with a clinically significant and progressive decrease in mental and physical health functioning as measured by the SF-36 Health Survey. This decline was independent of the presence of a DSM diagnosis. CONCLUSIONS: A primary care classification scheme for mood and anxiety symptoms that includes severity appears to provide more useful information than traditional DSM classifications of disorders.     

Medically unexplained symptoms and the problem of power in the primary care consultation: a qualitative study

BACKGROUND: Patients presenting in primary care frequently exhibit physical symptoms that may be unrelated to organic pathology. Such symptoms are commonly regarded as products of psychological or emotional problems, and their legitimacy as 'medical' matters is often called into question. OBJECTIVES: Our aim was to explore GPs' attitudes to the management of patients that present with medically unexplained symptoms in primary care. METHODS: Semi-structured interviews were conducted with 15 GPs in North-West England. Interviews were audio-taped and subsequently transcribed and analysed using a constant comparison technique. RESULTS: Subjects conceptualized patients presenting with medically unexplained symptoms as the presentation of psychological distress. They presented problems of control and authority in the consultation, and difficulties in managing this had a negative impact on the doctor-patient relationship. Such consultations were frustrating for the GP and potentially harmful to the patient. CONCLUSION: Patients with medically unexplained symptoms were seen to be presenting with inappropriate symptoms that were a manifestation of emotional or social distress. GPs felt ill-equipped to deal with the presentations and the frustrations they felt and may need help in actively and productively managing these patients.     

Feminist ethics and menopause: autonomy and decision-making in primary medical care

The construction of menopause as a long-term risk to health and the adoption of discourses of prevention has made necessary a decision by women about medical treatment; specifically regarding the use of hormone replacement therapy. In a study of general practitioners' accounts of menopause and treatment in Australia, women's 'choice', 'informed decision-making' and 'empowerment' were key themes through which primary medical care for women at menopause was presented. These accounts create a position for women defined by the concept of individual choice and an ethic of autonomy. These data are a basis for theorising more generally in this paper. We critically examine the construct of 'informed decision-making' in relation to several approaches to ethics including bioethics and a range of feminist ethics. We identify the intensification of power relations produced by an ethic of autonomy and discuss the ways these considerations inform a feminist ethics of decision-making by women. We argue that an 'ethic of autonomy' and an 'offer of choice' in relation to health care for women at menopause, far from being emancipatory, serves to intensify power relations. The dichotomy of choice, to take or not to take hormone replacement therapy, is required to be a choice and is embedded in relations of power and bioethical discourse that construct meanings about what constitutes decision-making at menopause. The deployment of the principle of autonomy in medical practice limits decision-making by women precisely because it is detached from the construction of meaning and the self and makes invisible the relations of power of which it is a part.     

Comparison of symptoms in Japanese and American depressed primary care patients.

BACKGROUND: Depression is a highly prevalent, worldwide problem with multiple social and health consequences. It often presents in primary care with physical symptoms. Little research has been done on cross-cultural expression of depression in primary care. This paper examines the hypothesis that depressed Japanese patients present with more and with more distinct somatic complaints than depressed American patients. METHODS: Data were collected by chart audit for patients with a diagnosis of depression at two sites: Minamikawachi Tochigi, Japan and Cleveland, Ohio, USA. Patient demographics and type and number of presenting symptoms in the two populations were compared. Logistic regression was used to determine whether there were differences between countries in physical symptoms and to adjust for relevant demographic characteristics. RESULTS: Japanese family physicians charted more somatic complaints from patients diagnosed as depressed than did American family physicians. Specific physical symptoms differed by country: Japanese patients had more abdominal distress, headaches, and neck pain. These symptoms have strong cultural significance for Japanese patients. CONCLUSIONS: This study clearly indicates the prominence and importance of physical symptoms in the presentation of depression in Japanese primary care patients. Their physicians must be alerted to the possibility of depression, especially when patient complaints include abdominal, neck or head pain.
