Symptoms and signs of colorectal cancer, with differences between proximal and distal colon cancer: a prospective cohort study of diagnostic accuracy in primary care.

BACKGROUND: In an abdominal symptom study in primary care in six European countries, 511 cases of cancer were recorded prospectively among 61,802 patients 16 years and older in Norway, Denmark, Sweden, Netherlands, Belgium and Scotland. Colorectal cancer is one of the main types of cancer associated with abdominal symptoms; hence, an in-depth subgroup analysis of the 94 colorectal cancers was carried out in order to study variation in symptom presentation among cancers in different anatomical locations. METHOD: Initial data capture was by completion of standardised forms containing closed questions about symptoms recorded during the consultation. Follow-up data were provided by the GP after diagnosis, based on medical record data made after the consultation. GPs also provided free text comments about the diagnostic procedure for individual patients. Fisher's exact test was used to analyse differences between groups. RESULTS: Almost all symptoms recorded could indicate colorectal cancer. 'Rectal bleeding' had a specificity of 99.4% and a PPV of 4.0%. Faecal occult blood in stool (FOBT) or anaemia may indicate gastrointestinal bleeding: when these symptoms and signs were combined, sensitivity reached 57.5%, with 69.2% for cancer in the distal colon. For proximal colon cancers, none of 18 patients had 'Rectal bleeding' at the initial consultation, but three of the 18 did so at a later consultation. 'Abdominal pain, lower part', 'Constipation' and 'Distended abdomen, bloating' were less specific and also less sensitive than 'Rectal bleeding', and with PPV between 0.7% and 1.9%. CONCLUSIONS: Apart from rectal bleeding, single symptoms did not reach the PPV 3% NICE threshold. However, supplementary information such as a positive FOBT or persistent symptoms may revise the PPV upwards. If a colorectal cancer is suspected by the GP despite few symptoms, the total clinical picture may still reach the NICE PPV threshold of 3% and justify a specific referral.

Awareness of parental illness: a grounded theory of upholding family equilibrium in parents on long-term sick-leave in primary health care.

OBJECTIVE: To understand the main concern of chronically ill parents and how they resolve this concern in relation to their children. DESIGN: Grounded theory. SETTING: Three primary health care clinics in Sweden. SUBJECTS: Thirty-two interviewed parents and their children. MAIN OUTCOME MEASURES: Processes and typologies of upholding family relationships. RESULTS: A concern of chronically ill parents is sustaining family equilibrium, achieved through a process of upholding family relationships. How a parent upholds depends upon his/her comprehension of the illness and of their child's need for parenting. In response to the parent's upholding behaviours, children mirror the effect of the illness to the parent, the child's specific behaviour depending on his/her level of comprehension regarding the parent's illness. Their combined behaviours create an awareness context that may be closed, concealed, suspicious, conflicted, mutual pretence or open.When the parent drives and facilitates the evolution of comprehension, the context quickly evolves from closed to open. When the parent hinders the process by masking and resisting the child responds by probing and proving and they become locked into a suspicious or conflicted awareness context with high relational tension. To create family equilibrium the parent needs to reveal and facilitate the awareness process. CONCLUSION: Parents on long-term sick leave in primary health care can need assistance to facilitate the awareness context of themselves and their child.Implications: Clinicians can identify the current awareness context of their patient and help their patient towards increased understanding of their illness; their child's needs and the parental capacities needed to reveal the illness and its impacts.Key PointsChildren are affected when parents are ill; they wish for information on their parent's illness. Effective interventions are available in settings other than primary health care and possibilities seen by GPs and families in Scandinavian primary health care have been previously described. There is a knowledge gap in how parents view themselves and their parenting when ill in primary health care. An analysis grounded in interviews was needed to generate a hypothesis (theory) of parental concerns and behaviours.This theory proposes that an important concern of chronically ill parents is to sustain family equilibrium, which they attempt to do by upholding family relationships.Specific upholding behaviours include masking, resisting, colluding, and revealing. In response, children will engage in mirroring behaviours. Which paired behaviours are enacted will depend upon the respective levels of comprehension of parent and child regarding the illness and on the child's need for parenting. In their interactions, parent and child create one of six awareness contexts.Identifying the current awareness context in the family about chronic parental illness provides clinicians with a conceptual tool to better support those families locked in suspicious or conflicted awareness contexts.

Two-year weight, risk and health factor outcomes of a weight-reduction intervention programme: Primary prevention for overweight in a multicentre primary healthcare setting.

Objective: To study the long-term effects of weight reduction, quality of life and sense of coherence in a primary health care (PHC)-based programme with two different intensities.Design: Prospective two-armed randomised intervention.Setting: Three PHC centres in south west of Sweden.Subjects: In total, 289 women and men aged 40-65 years with a BMI of 28-35 were recruited for a two-year weight-reduction programme. Participants were randomized to high-intensity or low-intensity groups. Blood samples, physical measurements and questionnaires were analysed. Participants received cookbooks and dietary lectures. The high-intensity group also received Motivational interviewing (MI), dietary advice on prescription (DAP- advice), a grocery store lecture, a website and weekly e-mails.Main outcome measures: Weight, quality of life, risks and health factors.Results: In total, 182 (64%) participants completed the 2-year follow-up. The total sample reduced their weight by 1 kg (p = 0.006). No significant differences regarding weight were found between the groups. Anxiety/depression decreased in EQ5-D (p = 0.021), EQ5-D VAS (p = 0.002) and SOC (p = 0.042). Between the groups, there were significant differences in EQ5-D usual activities (p = 0.004), anxiety/depression (p = 0.013), pain/discomfort (p = 0.041), fruit and vegetables (p = 0.005), HLV anxiety (p = 0.005), and visits to nurses (p = 0.012).Conclusion: The total population lost weight, and the high-intensity and low-intensity programmes did not result in significant differences in terms of weight. The high-intensity programme reported health benefits linked to lower levels of anxiety and depression, increased activity and intake of greens and reduced visits to physicians and nurses.Key pointsBoth groups had a consisting weight- reduction after two years.High intensity did not lead to a significant difference in weight reduction between the groups.The high-intensity group reported more health effects, such as better quality of life, reduced anxiety, and increased greenery intake. It is unknown how much support patients in a weight- reduction programme in PHC require to succeed with weight loss and a healthy lifestyle.

Diagnostic profile characteristics of cancer patients with frequent consultations in primary care before diagnosis: a case-control study.

Background: Many patients with common cancers are late diagnosed. Objectives: Identify consultation profiles and clinical features in patients with the seven most common cancers, who had consulted a general practitioner (GP) frequently before their cancer diagnosis. Methods: A case-control study was conducted in Region Västra Götaland, Sweden. A total of 2570 patients, diagnosed in 2011 with prostate, breast, colorectal, lung, gynaecological and skin cancers including malignant melanoma, and 9424 controls were selected from the Swedish Cancer Register and a regional health care database. Diagnostic codes [International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10)] from primary care for patients with ≥4 GP consultations registered in the year before cancer diagnosis were collected. Likelihood ratios (LRs) were calculated for variables associated with the different cancers. Results: Fifty-six percent of the patients had consulted a GP four or more times in the year before cancer diagnosis. Alarm symptoms or signs represented 60% of the codes with the highest LR, but only 40% of the 10 most prevalent codes. Breast lump had the highest LR, 11.9 [95% confidence interval (CI) 8.0-17.8]; abnormalities of plasma proteins had an LR of 5.0 (95% CI 3.0-8.2) and abnormal serum enzyme levels had an LR of 4.6 (95% CI 3.6-5.9). Early clinical features associated with cancer had been registered already at the first two GP consultations. Conclusion: One out of six clinical features associated with cancer were presented by cancer patients with four or more pre-referral consultations already at the two first consultations. These early clinical features that were focal and had benign characteristics might have been missed diagnostic opportunities.

Dietary advice on prescription: experiences with a weight reduction programme.

AIMS AND OBJECTIVES: To describe overweight persons' experiences with weight reduction and participation in the dietary advice on prescription. BACKGROUND: Approximately 20% of overweight individuals are able to successfully lose weight. Experiences from earlier weight reduction programmes indicate that those who succeed typically manage to avoid overeating to handle stress and have high motivation to lose weight. Those who fail have low self-control and engage in negative health behaviours such as eating when experiencing negative emotions and stress. DESIGN: The study used a descriptive qualitative design and was conducted at a Primary Health Care Centre in south-west Sweden. METHODS: The first nineteen study participants who completed the weight reduction programme in two years responded in writing to five open questions about their experiences with the programme. Data were analysed using inductive content analysis. RESULTS: The participants appreciated the face-to-face meetings with the nurse because they felt seen and listened to during these sessions. They also felt their life situations and self-discipline had an impact on how well they were able to follow the programme. Dietary advice on prescription advice was considered to be helpful for achieving behavioural changes and losing weight. People who succeeded in sustainably losing weight described the importance of support from partners or close friends. CONCLUSIONS: To achieve sustainable weight reduction, it is important to individualise the programme in order to address each person's life situation and the unique difficulties they may encounter. RELEVANCE TO CLINICAL PRACTICE: Motivational interviewing appears to be a good technique for developing a successful relationship between the nurse and the patient. The dietary advice on prescription advice was perceived to be a good way to improve food habits and can easily be used at many Primary Health Care Centres. Patient's partners should also be offered the opportunity to participate in the programme.

Increased consultation frequency in primary care, a risk marker for cancer: a case-control study.

OBJECTIVE: To identify early diagnostic profiles such as diagnostic codes and consultation patterns of cancer patients in primary care one year prior to cancer diagnosis. DESIGN: Total population-based case-control study. SETTING AND SUBJECTS: 4562 cancer patients and 17,979 controls matched by age, sex, and primary care unit. Data were collected from the Swedish Cancer Register and the Regional Healthcare Database. METHOD: We identified cancer patients in the Västra Götaland Region of Sweden diagnosed in 2011 with prostate, breast, colorectal, lung, gynaecological, and skin cancers including malignant melanoma. We studied the symptoms and diagnoses identified by diagnostic codes during a diagnostic interval of 12 months before the cancer diagnosis. MAIN OUTCOME MEASURES: Consultation frequency, symptom density by cancer type, prevalence and odds ratios (OR) for the diagnostic codes in the cancer population as a whole. RESULTS: The diagnostic codes with the highest OR were unspecified lump in breast, neoplasm of uncertain behaviour, and abnormal serum enzyme levels. The codes with the highest prevalence were hyperplasia of prostate, other skin changes and abdominal and pelvic pain. The frequency of diagnostic codes and consultations in primary care rose in tandem 50 days before diagnosis for breast and gynaecological cancer, 60 days for malignant melanoma and skin cancer, 80 days for prostate cancer and 100 days for colorectal and lung cancer. CONCLUSION: Eighty-seven percent of patients with the most common cancers consulted a general practitioner (GP) a year before their diagnosis. An increase in consultation frequency and presentation of any symptom should raise the GP's suspicion of cancer. Key points Knowledge about the prevalence of early symptoms and other clinical signs in cancer patients in primary care remains insufficient. • Eighty-seven percent of the patients with the seven most common cancers consulted a general practitioner 12 months prior to cancer diagnosis. • Both the frequency of consultation and the number of symptoms and diseases expressed in diagnostic codes rose in tandem 50-100 days before the cancer diagnosis. • Unless it is caused by a previously known disease, an increased consultation rate for any symptom should result in a swift investigation or referral from primary care to confirm or exclude cancer.

Breathlessness in everyday life from a patient perspective: a qualitative study using diaries.

OBJECTIVE: Breathlessness is a subjective symptom, which makes it difficult to define and understand. The aim of the present study was to illuminate how patients suffering from breathlessness experience their everyday life. METHOD: The study was a qualitative study, and the focus of the analysis was the patients' descriptions of their experiences of breathlessness using a diary with two unstructured questions for a period of 7 consecutive days. Sixteen participants: 7 men, mean age 65 ± 7 (range 55-73 years old), and 9 women, mean age 65 ± 9 (range 50-72 years old) participated in the study. RESULTS: Two themes emerged from the analysis: 1) Impaired quality of life and 2) symptom tolerance and adaptation. The theme "impaired quality of life" included the categories limited physical ability, psychological burdens, and social life barriers. The theme "symptom tolerance and adaptation" included importance of health care, social support, hobbies and leisure activities, and coping strategies. SIGNIFICANCE OF RESULTS: The findings in our study showed that patients, in spite of considerable difficulties with shortness of breath, found relief in several types of activities, in addition to drug therapy. The result indicates that the "biopsychosocial model" is an appealing approach that should be discussed further to gain a better understanding of breathlessness.

Symptoms and signs of urogenital cancer in primary care.

BACKGROUND: Urogenital cancers are common, accounting for approximately 20% of cancer incidence globally. Cancers belonging to the same organ system often present with similar symptoms, making initial management challenging. In this study, 511 cases of cancer were recorded after the date of consultation among 61,802 randomly selected patients presenting in primary care in six European countries: a subgroup analysis of urogenital cancers was carried out in order to study variation in symptom presentation. METHODS: Initial data capture was by completion of standardised forms containing closed questions about symptoms recorded during the consultation. The general practitioner (GP) provided follow-up data after diagnosis, based on medical record data made after the consultation. GPs also provided free text comments about the diagnostic procedure for individual patients. RESULTS: The most common symptoms were mainly associated with one or two specific types of cancer: 'Macroscopic haematuria' with bladder or renal cancer (combined sensitivity 28.3%), 'Increased urinary frequency' with bladder (sensitivity 13.3%) or prostatic (sensitivity 32.1%) cancer, or to uterine body (sensitivity 14.3%) cancer, 'Unexpected genital bleeding' with uterine cancer (cervix, sensitivity 20.0%, uterine body, sensitivity 71.4%). 'Distended abdomen, bloating' had sensitivity 62.5% (based on eight cases of ovarian cancer). In ovarian cancer, increased abdominal circumference and a palpable tumour also were important diagnostic elements. Specificity for 'Macroscopic haematuria' was 99.8% (99.7-99.8). PPV > 3% was noted for 'Macroscopic haematuria' and bladder or renal cancer combined, for bladder cancer in male patients. In males aged 55-74, PPV = 7.1% for 'Macroscopic haematuria' and bladder cancer. Abdominal pain was an infrequent symptom in urogenital cancers. CONCLUSIONS: Most types of urogenital cancer present with rather specific symptoms. If the GP considers ovarian cancer, increased abdominal circumference should be actively determined. Several cases were clarified through the GP's clinical examination, or laboratory investigations.

Lateral epicondylalgia. A quantitative and qualitative analysis of interdisciplinary cooperation and treatment choice in the Swedish health care system.

OBJECTIVE AND AIM: Interdisciplinary cooperation is essential to develop a broad range of knowledge and skills. The aim of this study was to describe health care professionals' treatment choices, their cooperation with other professionals and their perceptions of potential risks regarding treatments of acute lateral epicondylalgia (LE). DESIGN: A quantitative descriptive study design with a summative approach to qualitative analysis. ETHICAL ISSUES: The ethical committee was asked verbally for approval but, as this study was performed to develop an organised way to treat LE, it did not require approval. The four ethical aspects information, consent, confidentiality and the use of the study materials were all addressed. SUBJECTS: All orthopaedic surgeons, general practitioners, physiotherapists and occupational therapists in a county. METHODS: Questionnaire with 18 dichotomous, multiple-response, multiple-choice questions and three open-ended questions were analysed using quantitative cross-tab and qualitative content analysis with summative approach. RESULTS: The most common treatment choices were Non Steroidal Anti Inflammatory Drugs (NSAID), corticosteroid injections, training programmes, braces and ergonomics. Advantages from interdisciplinary cooperation were higher rated than disadvantages. The qualitative findings dealt with perceptions of interdisciplinary cooperation and resulted in three categories; right level of care, increased quality of care and decreased quality of care. Almost half of the physicians felt potential risks associated with their treatment methods. The qualitative findings dealt with perceptions of the potential risks and resulted in two categories: side effects and inadequate treatment. STUDY LIMITATIONS: The number of responses varied because some of the respondents did not answered all of the questions. CONCLUSION: Interdisciplinary cooperation in the treatment of patients with acute LE benefits the patients by shortening the rehabilitation period and provides health care professionals the opportunity for an improved learning and exchanging experiences. These basic conditions must be met to improve health care quality.

Informing children of their parent's illness: A systematic review of intervention programs with child outcomes in all health care settings globally from inception to 2019.

INTRODUCTION: Children are impacted when parents are ill. This systematic review gives an overview of the current state of research and extracts what children and parents found helpful in the interventions aimed at informing children of their parent's illness. METHODS: This review was registered with PROSPERO and conducted in accordance with PRISMA guidelines. Five health and social science databases were searched from inception to November 2019 to identify original, peer-reviewed articles in English describing effective interventions. The authors selected and reviewed the studies independently, and any inconsistencies were resolved by discussion in face-to-face meetings and emails. A descriptive synthesis of evidence-based concepts from quantitative and qualitative studies was conducted. RESULTS: A total of 13 892 titles and 144 full-text articles were reviewed with 32 selected for final inclusion, 21 quantitative, 11 qualitative and no mixed-method studies published from 1993 to November 2019. Most of the research was conducted in mental health, including substance abuse (n = 22), but also in cancer care (n = 6) and HIV care (n = 4). Most studies using quantitative method showed a small to moderately positive statistically significant intervention effect on the child's level of internalized symptoms. Content analysis of the results of studies employing qualitative methodology resulted in four concepts important to both children and parents in interventions (increased knowledge, more open communication, new coping strategies and changed feelings) and three additional concepts important to parents (observed changes in their children's behavior, the parent's increased understanding of their own child and the relief of respite). CONCLUSIONS: In the literature there is evidence of mild to moderate positive effects on the child's level of internalized symptoms as well as concepts important to children and parent's worth noting when trying to bridge the still existing knowledge gaps. In further efforts the challenges of implementation as well as adaptation to differing clinical and personal situations appear key to address.

A feasible lifestyle program for early intervention in patients with chronic obstructive pulmonary disease (COPD): a pilot study in primary care.

AIM: To evaluate the feasibility of a lifestyle program for early intervention in patients with COPD in a primary care population. METHODS: The study was performed in a Primary Health Care Centre in Western Sweden. During a four-week period, all smokers between 40-70 years of age were invited to answer a questionnaire and to perform spirometry. The intervention program included a specially designed smoking cessation program and programs for physical activity and diet. RESULTS: 84 smokers were included. 42% fulfilled the criteria for COPD. All of the COPD patients were in GOLD stage I and II. Among the COPD subjects, 38% were underweight and 56% had a low fat-free mass - both together indicating malnutrition and the need for nutritional treatment. By the end of the intervention program, 47% of the COPD patients had stopped smoking. CONCLUSIONS: The intervention program was feasible and effective with a very high smoking cessation rate.

Predictive factors of sustained return to work for persons with musculoskeletal disorders who participated in rehabilitation.

Musculoskeletal disorders (MSD) account for the majority of total morbidity cases in the working-age Swedish population. These disorders are thought to be the reason given for one-third of total certified sick leave requests. In addition to the high cost to society, MSD involve both physical and emotional suffering, pain and financial and social problems for the injured persons. The aim of this study was to identify predictive multidimensional factors for sustainable return to work (RTW) in a long-term follow-up persons with MSD. During the period 1992-1999, 385 persons participated in a rehabilitation program. Ten years later, 354 of these took part in a prospective follow-up study. The average post-rehabilitation time was ten years (range=7-13 years) and 243 persons (69%) completed a questionnaire. The "working full-time" group (n=110) and the "sick-listed" group (n=73) were included in the study. The two groups were compared in terms of predictors for RTW. Multiple stepwise logistic regression and bivariate analysis, as well as parametric and non-parametric tests, were used to identify predictive factors. The number of sick-listed days before rehabilitation, age, self-rated pain, life events, gender, physical capacity, self-rated functional capacity, educational level and light physical labor were predictors of long-term RTW. Return to work an be facilitated by planning at an early stage of the certified sick leave period using instrument that take these predictors into account.

Characteristics of patients seeking a health promotion and weight reduction program in primary care.

PURPOSE: An important task in primary health care (PHC) is to address lifestyle-related diseases. Overweight (OW) individuals make up a large proportion of PHC patients, and they increasingly have lifestyle-related illnesses that influence their quality of life. Structured health promotion and weight reduction programs could help these patients. The objective of this study was to explore the characteristics, lifestyle habits, and health conditions of individuals seeking a health promotion and weight reduction program in PHC. PATIENTS AND METHODS: The study involved a comparative cross-sectional design performed in PHC in southwestern Sweden. The study population comprised 286 participants (231 women, aged 40-65 years, body mass index [BMI] 28-35 kg/m2) who were recruited between March 2011 and April 2014 to the 2-year program by adverts in local newspapers and recruitment from three PHC centers. Two reference populations were used: a general population group and an OW group. The study population data were collected using a questionnaire, with validated questions regarding health, lifestyle, illnesses, and health care utilization. RESULTS: People seeking a health promotion and weight reduction program were mostly women. They had a higher education level and experienced worse general health than the OW population, and they visited PHC more frequently than both reference groups. They also felt more stressed, humiliated, had more body pain, and smoked less compared to the general population. However, they did not exercise less or had a lower intake of fruits and vegetables than either reference population. CONCLUSION: Individuals seeking a weight reduction program were mostly women with a higher education level and a worse general health than the OW population. They used more health care services compared to the reference groups.

Cross-cultural adaptation and determination of the reliability and validity of PRTEE-S (Patientskattad Utvärdering av Tennisarmbåge), a questionnaire for patients with lateral epicondylalgia, in a Swedish population.

BACKGROUND: In Sweden, as well as in Scandinavia, there is no easy way to evaluate patients' difficulties when they suffer from lateral epicondylitis/epicondylalgia. However, there is a Canadian questionnaire, in English, that could make the evaluation of a patient's pain and functional loss both quick and inexpensive. Therefore, the aim of this study was to translate and cross-culturally adapt the questionnaire "Patient-rated Tennis Elbow Evaluation" into Swedish (PRTEE-S; "Patientskattad Utvärdering av Tennisarmbåge"), and to evaluate the reliability and validity of the test. METHODS: The Patient-rated Tennis Elbow Evaluation was cross-culturally adapted for the Swedish language according to well-established guidelines. Fifty-four patients with unilateral epicondylitis/epicondylalgia were assessed using the PRTEE-S (Patientskattad Utvärdering av Tennisarmbåge), the Disabilities of Arm, Shoulder, and Hand questionnaire, and the Roles & Maudsley score to establish the validity and reliability of the PRTEE-S. Reliability was determined via calculation of the intra-class correlation coefficient (ICC) the internal consistency was assessed by Cronbach's alpha, and validity was calculated using Spearman's correlation coefficient. RESULTS: The test-retest reliability, using the PRTEE-S (Patientskattad Utvärdering av Tennisarmbåge) intraclass correlation coefficient, was 0.95 and the internal consistency was 0.94. The PRTEE-S correlated well with the Disabilities of the Arm, Shoulder, and Hand questionnaire (r = 0.88) and the Roles & Maudsley score (r = 0.78). CONCLUSION: The PRTEE-S (Patientskattad Utvärdering av Tennisarmbåge) represents a reliable and valid instrument to evaluate the subjective outcome in Swedish speaking patients with lateral epicondylitis/epicondylalgia, and can be used in both research and clinical settings.

Clinical features of patients with non-metastatic lung cancer in primary care: a case-control study.

BACKGROUND: Lung cancer (LC) kills more people than any other cancer globally, mainly due to the late stage of diagnosis. AIM: To identify and quantify the prediagnostic features of non-metastatic lung cancer (nMLC) and to compare the clinical features in GPs' chest X-ray referral letters with the clinical features (expressed as diagnostic codes) in medical records. DESIGN & SETTING: A population-based case-control study was conducted using diagnostic codes from national and regional healthcare databases in Sweden. METHOD: In total, 373 patients diagnosed with LC in 2011 (of which 132 had nMLC) and 1472 controls were selected from the Swedish Cancer Register (SCR) and regional healthcare database, respectively. Diagnostic codes registered in medical records from primary care consultations in the year before LC diagnosis were collected from the regional healthcare database. Odds ratios (OR) were calculated for variables associated with nMLC. The GPs' referral letters for chest X- ray were retrieved from the regional repository for radiology. RESULTS: Clinical features with the highest OR were vitamin B12 deficiency anaemia (OR 6.7, 95% confidence interval [CI] = 1.6 to 27.9), dyspnoea (OR 5.0, 95% CI = 2.0 to 12.7), and chronic bronchitis (OR 5.0, 95% CI = 1.3 to 18.6). Clinical features that were GPs' reasons for requesting chest X-ray were almost three times more frequent in referral letters compared to the corresponding diagnostic codes in the medical records. CONCLUSION: Patients with nMLC could not be identified by symptoms. The clinical features in referral letters for X-ray were more frequent than corresponding diagnostic codes from medical records.

Abdominal symptoms and cancer in the abdomen: prospective cohort study in European primary care.

BACKGROUND: Different abdominal symptoms may signal cancer, but their role is unclear. AIM: To examine associations between abdominal symptoms and subsequent cancer diagnosed in the abdominal region. DESIGN AND SETTING: Prospective cohort study comprising 493 GPs from surgeries in Norway, Denmark, Sweden, Scotland, Belgium, and the Netherlands. METHOD: Over a 10-day period, the GPs recorded consecutive consultations and noted: patients who presented with abdominal symptoms pre-specified on the registration form; additional data on non-specific symptoms; and features of the consultation. Eight months later, data on all cancer diagnoses among all study patients in the participating general practices were requested from the GPs. RESULTS: Consultations with 61 802 patients were recorded and abdominal symptoms were documented in 6264 (10.1%) patients. Malignancy, both abdominal and non-abdominal, was subsequently diagnosed in 511 patients (0.8%). Among patients with a new cancer in the abdomen (n = 251), 175 (69.7%) were diagnosed within 180 days after consultation. In a multivariate model, the highest sex- and age-adjusted hazard ratio (HR) was for the single symptom of rectal bleeding (HR 19.1, 95% confidence interval = 8.7 to 41.7). Positive predictive values of >3% were found for macroscopic haematuria, rectal bleeding, and involuntary weight loss, with variations according to age and sex. The three symptoms relating to irregular bleeding had particularly high specificity in terms of colorectal, uterine, and bladder cancer. CONCLUSIONS: A patient with undiagnosed cancer may present with symptoms or no symptoms. Irregular bleeding must always be explained. Abdominal pain occurs with all types of abdominal cancer and several symptoms may signal colorectal cancer. The findings are important as they influence how GPs think and act, and how they can contribute to an earlier diagnosis of cancer.

Abdominal symptoms in general practice: Frequency, cancer suspicions raised, and actions taken by GPs in six European countries. Cohort study with prospective registration of cancer.

BACKGROUND: Abdominal symptoms are diagnostically challenging to general practitioners (GPs): although common, they may indicate cancer. In a prospective cohort of patients, we examined abdominal symptom frequency, initial diagnostic suspicion, and actions of GPs in response to abdominal symptoms. METHODS: Over a 10-day period, 493 GPs in Norway, Denmark, Sweden, Belgium, the Netherlands, and Scotland, recorded consecutive consultations: sex, date of birth and any specified abdominal symptoms. For patients with abdominal symptoms, additional data on non-specific symptoms, GPs' diagnostic suspicion, and features of the consultation were noted. Data on all cancer diagnoses among all included patients were requested from the GPs eight months later. FINDINGS: Consultations with 61802 patients were recorded. Abdominal symptoms were recorded in 6264 (10.1%) patients. A subsequent malignancy was reported in 511 patients (0.8%): 441 (86.3%) had a new cancer, 70 (13.7%) a recurrent cancer. Abdominal symptoms were noted in 129 (25.2%) of cancer patients (P < 0.001), rising to 34.5% for the 89 patients with cancer located in the abdominal region. PPV for any cancer given any abdominal symptom was 2.1%. In symptomatic patients diagnosed with cancer, GPs noted a suspicion of cancer for 85 (65.9%) versus 1895 (30.9%) when there was no subsequent cancer (P < 0.001). No suspicion was noted in 32 (24.8%) cancer patients. The GP's intuitive cancer suspicion was independently associated with a subsequent new cancer diagnosis (OR 2.11, 95% CI 1.15-3.89). Laboratory tests were ordered for 45.4% of symptomatic patients, imaging for 10.4%, referral or hospitalization for 20.0%: all were more frequent in subsequent cancer patients (P < 0.001). INTERPRETATION: Abdominal symptoms pointed to abdominal cancers rather than to other cancers. However, the finding of abdominal symptoms in only one third of patients with an abdominal cancer, and the lack of cancer suspicion in a quarter of symptomatic cancer patients, provide challenges for GPs' diagnostic thinking and referral practices.

Sleep disturbances in midlife unrelated to 32-year diabetes incidence: the prospective population study of women in Gothenburg.

OBJECTIVE: To study the relation between diabetes incidence and sleep problems in a population-based sample of women followed for 32 years. RESEARCH DESIGN AND METHODS: The researchers conducted a prospective population study initiated in 1968-1969, with follow-ups in 1974-1975, 1980-1981, 1992-1993, and 2000-2001 in Gothenburg, Sweden. A total of 1,462 women born in 1908, 1914, 1918, 1922, and 1930, representative of women of the same ages in the general population, initially participated (90% participation rate). Reported sleep duration, sleep problems, and use of sleeping medication were related to incident diabetes from 1968 to 2000. Associations between sleep problems and diabetes were corrected for waist-to-hip ratio (WHR), BMI, subscapular skinfold, fasting blood glucose and serum lipid concentrations, blood pressure, heart rate, smoking, physical activity, education, and socioeconomic status. Additionally, associations between BMI, WHR, and sleep problems were examined. RESULTS: Over 32 years, 126 women (8.7%) developed diabetes. Associations between diabetes and initial sleep problems were tested in a Cox regression analysis, taking into consideration factors associated (P < 0.1) with diabetes. Sleep problems in 1968 did not increase risk of developing diabetes during the following 32 years. Obesity, particularly centralized, was associated with sleep problems. CONCLUSIONS: No association between sleep problems and developing diabetes was seen in this 32-year follow-up of middle-aged women. Obesity, on the other hand, known to cause increased risk of diabetes, was associated with current sleep problems.

Identification of patients with non-metastatic colorectal cancer in primary care: a case-control study.

BACKGROUND: Colorectal cancer is the third most common cancer worldwide and second most common in Europe. Despite screening, it is often diagnosed at an unfavourable stage. AIM: To identify and quantify features of non-metastatic colorectal cancer in primary care to enable earlier diagnosis by GPs. DESIGN AND SETTING: A case-control study was conducted using diagnostic codes from national and regional healthcare databases in Sweden. METHOD: A total of 542 patients diagnosed with non-metastatic colorectal cancer in 2011 and 2139 matched controls were selected from the Swedish Cancer Register (SCR) and a regional healthcare database respectively. All diagnostic codes (according to ICD-10) from primary care consultations registered the year before the date of cancer diagnosis (according to the SCR) were collected from the regional database. Odds ratios were calculated for variables independently associated with non-metastatic colorectal cancer using multivariable conditional logistic regressions. Positive predictive values (PPVs) of these variables were calculated, both individually and in combination with each other. RESULTS: Five features were associated with colorectal cancer before diagnosis: bleeding, including rectal bleeding, melaena, and gastrointestinal bleeding (PPV 3.9%, 95% confidence interval [CI] = 2.3 to 6.3); anaemia (PPV 1.4%, 95% CI = 1.1 to 1.8); change in bowel habit (PPV 1.1%, 95% CI = 0.9 to 1.5; abdominal pain (PPV 0.9%, 95% CI = 0.7 to 1.1); and weight loss (PPV 1.0%, 95% CI = 0.3 to 3.0); all P-value <0.05. The combination of bleeding and change in bowel habit had a PPV of 13.7% (95% CI = 2.1 to 54.4); for bleeding combined with abdominal pain this was 12.2% (95% CI = 1.8 to 51.2). A risk assessment tool for non-metastatic colorectal cancer was designed. CONCLUSION: Bleeding combined with either diarrhoea, constipation, change in bowel habit, or abdominal pain are the most powerful predictors of non-metastatic colorectal cancer and should result in prompt referral for colorectal investigation.
